guidelines (utilizing the prices utilized in such year end reserve report), in

       latest audited financial statements; minus

               (b) the sum of:

               (i) Minority Interests;

               (ii) to the extent included in (a)(i) above, any net gas

definition of Permitted Business Investments by which the Company maintains an
interest in oil and gas reserves, reflected in the Company's latest audited
financial statements;

               (iii) to the extent included in (a) (i) above, the discounted
future net revenues, calculated in accordance with SEC guidelines (utilizing the
prices utilized in the Company's year end reserve report), attributable to
reserves which are required to be delivered to third parties to fully satisfy
the obligations of the Company, its Restricted Subsidiaries, Triton
International Oil Corporation, and any other vehicle permitted pursuant to the
definition of Permitted Business Investments by which the Company maintains an

assumptions included in determining the discounted future net revenues specified
(a) (i) above, would be necessary to fully satisfy the payment obligations of

determination, with respect to any Person, the ratio of (x) the aggregate amount
of Consolidated EBITDA of such Person for the period of the most recent four
consecutive fiscal quarters ending prior to the date of such determination for
which financial statements are in existence to (y) Consolidated Interest Expense
for such four fiscal quarters, provided, however, that:

       (1)     if the Company or any Restricted Subsidiary:

               (a)    has Incurred any Indebtedness since the beginning of such
                      period that remains outstanding on such date of
                      determination or if the transaction giving rise to the
                      need to calculate the Consolidated Coverage Ratio is an
                      Incurrence of Indebtedness, or both, Consolidated EBITDA
                      and Consolidated Interest Expense for such period will be
                      calculated after giving effect on a pro forma basis to
                      such Indebtedness as if such Indebtedness had been
                      Incurred on the first day of such period (except that in
                      making such computation, the amount of Indebtedness under
                      any revolving credit facility outstanding on the date of
                      such calculation will be computed based on (i) the average
                      daily balance of such Indebtedness during such four fiscal
                      quarters or such shorter period for which such facility
                      was outstanding or (ii) if such facility was created after
                      the end of such four fiscal quarters, the average daily
                      balance of such Indebtedness during the period from the
                      date of creation of such facility to the date of such
                      calculation) and the discharge of any other Indebtedness
                      repaid, repurchased,

                                                                               9


                 defeased or otherwise discharged with the proceeds of such new
                 Indebtedness as if such discharge had occurred on the first day
                 of such period; or

          (b)    has repaid, repurchased, defeased or otherwise discharged any
                 Indebtedness since the beginning of the period that is no
                 longer outstanding on such date of determination or if the
                 transaction giving rise to the need to calculate the
                 Consolidated Coverage Ratio involves a discharge of
                 Indebtedness (in each case other than Indebtedness incurred
                 under any revolving credit facility unless such Indebtedness
                 has been permanently repaid and the related commitment
                 terminated), Consolidated EBITDA and Consolidated Interest
                 Expense for such period will be calculated after giving effect
                 on a pro forma basis to such discharge of such Indebtedness,
                 including with the proceeds of such new Indebtedness, as if
                 such discharge had occurred on the first day of such period;

(2)       if since the beginning of such period the Company or any Restricted
          Subsidiary will have made any Asset Disposition or if the transaction
          giving rise to the need to calculate the Consolidated Coverage Ratio
          is an Asset Disposition:

          (a)    the Consolidated EBITDA for such period will be reduced by an
                 amount equal to the Consolidated EBITDA (if positive) directly
                 attributable to the assets which are the subject of such Asset
                 Disposition for such period or increased by an amount equal to
                 the Consolidated EBITDA (if negative) directly attributable
                 thereto for such period; and

          (b)    Consolidated Interest Expense for such period will be reduced
                 by an amount equal to the Consolidated Interest Expense
                 directly attributable to any Indebtedness of the Company or any
                 Restricted Subsidiary repaid, repurchased, defeased or
                 otherwise discharged with respect to the Company and its
                 continuing Restricted Subsidiaries in connection with such
                 Asset Disposition for such period (or, if the Capital Stock of
                 any Restricted Subsidiary is sold, the Consolidated Interest
                 Expense for such period directly attributable to the
                 Indebtedness of such Restricted Subsidiary to the extent the
                 Company and its continuing Restricted Subsidiaries are no
                 longer liable for such Indebtedness after such sale);

(3)       if since the beginning of such period the Company or any Restricted
          Subsidiary (by merger or otherwise) will have made an Investment in
          any Restricted Subsidiary (or any Person which becomes a Restricted
          Subsidiary or is merged with or into the Company) or an acquisition of
          assets, including any acquisition of assets occurring in connection
          with a transaction causing a calculation to be made hereunder, which
          constitutes all or substantially all of an operating unit, division or
          line of business, Consolidated EBITDA and Consolidated Interest
          Expense for such period will be calculated after giving pro


<PAGE>   16

                                                                              10


               forma effect thereto (including the Incurrence of any
               Indebtedness) as if such Investment or acquisition occurred on
               the first day of such period; and

       (4)     if since the beginning of such period any Person (that
               subsequently became a Restricted Subsidiary or was merged with or
               into the Company or any Restricted Subsidiary since the beginning
               of such period) will have made any Asset Disposition or any
               Investment or acquisition of assets that would have required an
               adjustment pursuant to clause (2) or (3) above if made by the
               Company or a Restricted Subsidiary during such period,
               Consolidated EBITDA and Consolidated Interest Expense for such
               period will be calculated after giving pro forma effect thereto
               as if such Asset Disposition or Investment or acquisition of
               assets occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to any
calculation under this definition, the pro forma calculations will be determined
in good faith by a responsible financial or accounting officer of the Company
(including pro forma expense and cost savings following an acquisition resulting
from employee termination, facilities consolidations and closings,
standardization of employee benefits and compensation practices, consolidation
of property, casualty and other insurance coverage and policies, standardization
of sales representation commissions and other contract rates, and reductions in
taxes other than income taxes (collectively, "Cost Savings Measures"), which
cost savings the Company reasonably believes in good faith could have been
achieved during such four quarter period as a result of any such acquisition
(regardless of whether such cost savings could then be reflected in pro forma
financial statements under GAAP, Regulation S-X promulgated by the SEC or any
other regulation or policy of the SEC), less the amount of any additional
expenses that the Company reasonably estimates would result from anticipated
replacement of any items constituting Cost Savings Measures in connection with
such acquisitions; provided, however, that both (A) such cost savings and Cost
Savings Measures were identified and such cost savings were quantified in an
Officers' Certificate delivered to the Trustee at the time of the consummation
of such acquisition and (B) with respect to each such acquisition completed
prior to the 90th day preceding such date of determination, actions were
commenced or initiated by the Company within 90 days of such acquisition to
effect the Cost Savings Measures identified in such Officers' Certificate
(regardless, however, of whether the corresponding cost savings have been
achieved). If any Indebtedness bears a floating rate of interest and is being
given pro forma effect, the interest expense on such Indebtedness will be
calculated as if the rate in effect on the date of determination had been the
applicable rate for the entire period (taking into account any Interest Rate
Agreement applicable to such Indebtedness if such Interest Rate Agreement has a
remaining term in excess of 12 months).

               "Consolidated EBITDA" for any period means, without duplication,
the Consolidated Net Income for such period, plus the following to the extent
deducted in calculating such Consolidated Net Income:

       (1)     Consolidated Interest Expense;

<PAGE>   17

                                                                              11


       (2)     Consolidated Income Taxes;

       (3)     consolidated depreciation expense;

       (4)     consolidated amortization of intangibles;

       (5)     exploration and abandonment expense (if applicable); and

       (6)     other non-cash charges reducing Consolidated Net Income
               (excluding any such non-cash charge to the extent it represents
               an accrual of or reserve for cash charges in any future period or
               amortization of a prepaid cash expense that was paid in a prior
               period not included in the calculation)

and less, to the extent included in calculating such Consolidated Net Income and
in excess of any costs or expenses attributable thereto and deducted in
calculating such Consolidated Net Income, the sum of (x) the amount of deferred
revenues that are amortized during such period and are attributable to reserves
that are subject to Volumetric Production Payments, and (y) amounts recorded in
accordance with GAAP as repayments of principal and interest pursuant to
Dollar-Denominated Production Payments. Notwithstanding the preceding sentence,
clauses (2) through (6) relating to amounts of a Restricted Subsidiary of a
Person will be added to Consolidated Net Income to compute Consolidated EBITDA
of such Person only to the extent (and in the same proportion) that the net
income (loss) of such Restricted Subsidiary was included in calculating the
Consolidated Net Income of such Person and only if a corresponding amount would

               (d) Book-Entry Provisions. (i) This Section 2.1(d) shall apply

               (ii) Each Global Security initially shall (x) be registered in

their behalf by DTC or by the Trustee as the custodian of DTC or under such
Global Security, and DTC may be treated by the Company, the Trustee and any
agent of the Company or the Trustee as the absolute owner 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

beneficial interest in a Global Security pursuant to subsection (e) of this
Section to beneficial owners who are required to hold Definitive Securities, the
Securities Custodian shall reflect on its books and records the date and a

Registrar's procedures. In addition, Definitive Securities shall be transferred
to all beneficial owners in exchange for their beneficial interests in a Global
Security if (a) DTC notifies the Company that it is unwilling or unable to
continue as depositary for such Global Security or DTC ceases to be a clearing
agency registered under the Exchange Act, at a time when DTC is required to be
so registered in order to act as depositary, and in each case a successor
depositary is not appointed by the Company within 90 days of such notice or, (b)
the Company executes and delivers to the Trustee and Registrar an Officers'
Certificate stating that such Global Security shall be so exchangeable or (c) an
Event of Default has occurred and is continuing and the Registrar has received a
request from DTC or the Trustee.

regarding transfer restrictions applicable to the Definitive Security set forth
in Section 2.1(c).

Definitive Security for a beneficial interest in a Global Security, the Trustee
shall cancel such Definitive Security, and the Company shall execute, and the
Trustee shall authenticate and deliver, to the transferring Holder a new
Definitive Security representing the principal amount not so transferred.

               SECTION 2.2. Execution and Authentication. One Officer shall sign
the Securities for the Company by manual or facsimile signature. If an Officer
whose signature is on a Security no longer holds that office at the time the
Trustee authenticates the Security, the Security shall be valid nevertheless,
after giving effect to any exchange of Initial Securities (and any Subsequent
Series Securities) for Exchange Securities.

               A Security shall not be valid until an authorized signatory of
the Trustee manually authenticates the Security. The signature of the Trustee on
a Security shall be conclusive evidence that such Security has been duly and
validly authenticated and issued under this Indenture. A Security shall be dated
the date of its authentication.

               At any time and from time to time after the execution and
delivery of this Indenture, the Trustee shall authenticate and make available
for delivery: (1) Original Securities for original issue on the Issue Date in an
aggregate principal amount of $300.0 million and (2) Exchange Securities for
issue only in a Registered Exchange Offer pursuant to the Exchange and
Registration Rights Agreement, and only in exchange for Initial Securities (and
any Subsequent Series Securities) of an equal principal amount, in each case
upon a written order of the Company signed by two Officers or by an Officer and
either an Assistant Treasurer or an Assistant Secretary of the Company (the
"Company Order"). Such Company Order shall specify the amount of the Securities
to be authenticated and the date on which the original issue of Securities is to
be authenticated and whether the Securities are to be Initial Securities,
Subsequent Series Securities or Exchange Securities. The aggregate principal
amount of securities which may be authenticated and delivered under this
Indenture is limited to $500.0 million

outstanding, including (a) $300.0 million in aggregate principal amount of
Securities being offered on the Issue Date and (b) additional series of
securities which may be offered subsequent to the Issue Date (the "Subsequent
Series Securities") in aggregate principal amount not to exceed $200.0 million,
in each case upon receipt of a Company Order, Officer's Certificate and Opinion
of Counsel, except for Securities authenticated and delivered upon registration
of transfer of, or in exchange for, or in lieu of, other Securities of the same
class pursuant to Section 2.6, Section 2.9, Section 2.11, Section 3.6, Section
3.8, Section 5.8 and Section 9.5, and except for transactions similar to the
Registered Exchange Offer; provided, however, that no Subsequent Series
Securities may be authenticated and delivered in an aggregate principal amount
of less than $10,000,000. All Securities issued on the Issue Date and all
Subsequent Series Securities shall be identical in all respects other than issue
dates, the date from which interest accrues and any changes relating thereto.
Notwithstanding anything to the contrary contained in this Indenture, all notes
issued under this Indenture shall vote and consent together on all matters as
one class and no series of notes will have the right to vote or consent as a
separate class on any matter.

               The Trustee may appoint an agent (the "Authenticating Agent")
reasonably acceptable to the Company to authenticate the Securities. Unless
limited by the terms of such appointment, any such Authenticating Agent may
authenticate Securities whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by the
Authenticating Agent.

               In case the Company, pursuant to Article IV, shall be
consolidated or merged with or into any other Person or shall convey, transfer,
lease or otherwise dispose of its properties and assets substantially as an
entirety to any Person, and the successor Person resulting from such
consolidation, or surviving such merger, or into which the Company shall have
been merged, or the Person which shall have received a conveyance, transfer,
lease or other disposition as aforesaid, shall have executed an indenture
supplemental hereto with the Trustee pursuant to Article IV, any of the
Securities authenticated or delivered prior to such 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
Securities as specified in such order for the purpose of such exchange. If
Securities shall at any time be authenticated and delivered in any new name of a
successor Person pursuant to this Section 2.2 in exchange or substitution for or
upon registration of transfer of any Securities, such successor Person, at the
option of the Holders but without expense to them, shall provide for the
exchange of all Securities at the time outstanding for Securities authenticated
and delivered in such new name.

               SECTION 2.3. Registrar and Paying Agent. The Company shall
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The

                                                                              45


Company shall cause each of the Registrar and the Paying Agent to maintain an
office or agency in the Borough of Manhattan, The City of New York. The
Registrar shall keep a register of the Securities and of their transfer and
exchange (the "Note Register"). The Company may have one or more co- registrars
and one or more additional paying agents. The term "Paying Agent" includes any
additional paying agent.

               The Company shall enter into an appropriate agency agreement with
any Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of each such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.7. The
Company or any of its Restricted Subsidiaries may act as Paying Agent,
Registrar, co-registrar or transfer agent.

               The Company initially appoints the Trustee as Registrar and
Paying Agent for the Securities.

               SECTION 2.4. Paying Agent To Hold Money in Trust. By at least
10:00 a.m. (New York City time) on the date on which any principal of or
interest on any Security is due and payable, the Company shall deposit with the
Paying Agent a sum sufficient to pay such principal or interest when due. The
Company shall require each Paying Agent (other than the Trustee) to agree in
writing that such Paying Agent shall hold in trust for the benefit of Holders or
the Trustee all money held by such Paying Agent for the payment of principal of
or interest on the Securities and shall notify the Trustee in writing of any
default by the Company in making any such payment. If the Company or a
Subsidiary acts as Paying Agent, it shall segregate the money held by it as
Paying Agent and hold it as a separate trust fund. The Company at any time may
require a Paying Agent (other than the Trustee) to pay all money held by it to
the Trustee and to account for any funds disbursed by such Paying Agent. Upon
complying with this Section, the Paying Agent (if other than the Company or a
Subsidiary) shall have no further liability for the money delivered to the
Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect
to the Company, the Trustee shall serve as Paying Agent for the Securities.

               SECTION 2.5. Holder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Holders. If the Trustee is not the Registrar, or
to the extent otherwise required under the TIA, the Company shall furnish to the
Trustee, in writing at least seven Business Days before each interest payment
date and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Holders.

               (c) Restricted Securities Legend. Upon the transfer, exchange or
replacement of Securities not bearing a Restricted Securities Legend, the

the related restrictions on transfer are required in order to maintain

               (d) The Registrar shall retain copies of all letters, notices and

       II, execute and the Trustee shall authenticate Definitive Securities and

                     (ii) No service charge shall be made to a Holder for any
       registration of transfer or exchange, but the Company may require payment
       of a sum sufficient to cover any transfer tax, assessments, or similar
       governmental charge payable in connection therewith (other than any such
       transfer taxes, assessments or similar governmental charges payable upon
       exchange or transfer pursuant to Sections 3.6, 3.8 or 9.5).

       business on the day of such mailing or (2) 15 days before an interest
       payment date and ending on such interest payment date.

                     (iv) Prior to the due presentation for registration of
       transfer of any Security, the Company, the Trustee, the Paying Agent, the
       Registrar or any co-registrar may deem and treat the Person in whose name
       a Security is registered as the absolute owner of such Security for the
       purpose of receiving payment of principal of and interest on such
       Security and for all other purposes whatsoever, whether or not such
       Security is overdue, and none of the Company, the Trustee, the Paying
       Agent, the Registrar or any co-registrar shall be affected by notice to
       the contrary.

                     (v) Any Definitive Security delivered in exchange for an
       interest in a Global Security pursuant to Section 2.1(d) shall, except as
       otherwise provided by Section 2.6(c), bear the applicable legend
       regarding transfer restrictions applicable to the Definitive Security set
       forth in Section 2.1(c).

                     (vi) All Securities issued upon any transfer or exchange
       pursuant to the terms of this Indenture shall evidence the same debt and

       Securities surrendered upon such registration of transfer or exchange.

               (f) No Obligation of the Trustee. (i) The Trustee shall have no
responsibility or obligation to any beneficial owner of a Global Security, a
member of, or a participant in, DTC or other Person with respect to the accuracy
of the records of DTC or its nominee or of any participant or member thereof,
with respect to any ownership interest in the Securities or with respect to the
delivery to any participant, member, beneficial owner or other Person (other
than DTC) of any notice (including any notice of redemption) or the payment of
any amount or delivery of any Securities (or other security or property) under

to the Holders and all payments to be made to Holders in respect of the
Securities shall be given or made only to or upon the order of the registered
Holders (which shall be DTC or its nominee in the case of a Global Security).
The rights of beneficial owners in any Global Security shall be exercised only
through DTC subject to the applicable rules and procedures of DTC. The Trustee
may rely and shall be fully protected in relying upon information furnished by
DTC with respect to its members, participants and any beneficial owners.

               (ii) The Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restrictions on transfer imposed
under this Indenture or under applicable law with respect to any transfer of any
interest in any Security (including any transfers between or among DTC
participants, members or beneficial owners in any Global Security) other than to
require delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by, the terms
of this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

Attention:  Capital Markets Fiduciary Services

Dear Sirs:

               This certificate is delivered to request a registration of
transfer of $      principal amount of the 8 7/8% Senior Notes due 2007 (the
"Securities") of Triton Energy Limited (the "Company").

               Upon registration of transfer, the Securities would be registered
in the name of the new record owner as follows:

               Name:
                    ---------------------------------------------

               Address:

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

               The undersigned represents and warrants to you that:

               1. We are an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended
(the "Securities Act")) purchasing for our own account or for the account of
such an institutional "accredited investor" at least $250,000 principal amount
of the Securities, and we are acquiring the Securities not with a view to, or
for offer or sale in connection with, any distribution in violation of the
Securities Act. We have such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risk of our investment in
the Securities and we invest in or purchase securities similar to the Securities
in the normal course of our business. We and any accounts for which we are
acting are each able to bear the economic risk of our or its investment.

               2. We understand that the Securities have not been registered
under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of
any investor account for which we are purchasing Securities to

                                                                              50


offer, sell or otherwise transfer such Securities prior to the date that is two
years after the later of the date of original issue and the last date on which
the Company or any Affiliate of the Company was the owner of such Securities (or
any predecessor thereto) (the "Resale Restriction Termination Date") only (a) to
the Company, (b) pursuant to a registration statement which has been declared
effective under the Securities Act, (c) in a transaction complying with the
requirements of Rule 144A under the Securities Act, to a Person we reasonably
believe is a qualified institutional buyer under Rule 144A (a "QIB") that
purchases for its own account or for the account of a QIB and to whom notice is
given that the transfer is being made in reliance on Rule 144A, (d) pursuant to
offers and sales that occur outside the United States within the meaning of
Regulation S under the Securities Act, (e) to an institutional "accredited
investor" within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
Securities Act that is purchasing for its own account or for the account of such
an institutional "accredited investor," in each case in a minimum principal
amount of Securities of $250,000 or (f) pursuant to any other available
exemption from the registration requirements of the Securities Act, subject in
each of the foregoing cases to any requirement of law that the disposition of
our property or the property of such investor account or accounts be at all
times within our or their control and in compliance with any applicable state
securities laws. The foregoing restrictions on resale will not apply subsequent
to the Resale Restriction Termination Date. If any resale or other transfer of
the Securities is proposed to be made pursuant to clause (e) above prior to the
Resale Restriction Termination Date, the transferor shall deliver a letter from
the transferee substantially in the form of this letter to the Company and the
Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" (within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act) and that it is acquiring such Securities
for investment purposes and not for distribution in violation of the Securities
Act. Each purchaser acknowledges that the Company and the Trustee reserve the
right prior to any offer, sale or other transfer prior to the Resale Termination
Date of the Securities pursuant to clauses (d), (e) or (f) above to require the
delivery of an opinion of counsel, certifications and/or other information
satisfactory to the Company and the Trustee.

amount of the Securities, we confirm that such sale has been effected pursuant
to and in accordance with Regulation S under the United States Securities Act of

               (a) the offer of the Securities was not made to a Person in the
       United States;

               (b) either (i) at the time the buy order was originated, the
       transferee was outside the United States or we and any Person acting on
       our behalf reasonably believed that the transferee was outside the United
       States or (ii) the transaction was executed in, on or through the
       facilities of a designated off-shore securities market and neither we nor
       any Person acting on our behalf knows that the transaction has been
       pre-arranged with a buyer in the United States;

               (c) no directed selling efforts have been made in the United
       States in contravention of the requirements of Rule 903(b) or Rule 904(b)
       of Regulation S, as applicable; and

               (d) the transaction is not part of a plan or scheme to evade the
       registration requirements of the Securities Act.

               In addition, if the sale is made during a restricted period and
the provisions of Rule 903(c)(3) or Rule 904(c)(1) of Regulation S are
applicable thereto, we confirm that such sale has been made in accordance with

a mutilated Security is surrendered to the Registrar or if the Holder of a
Security claims that the Security has been lost, destroyed or wrongfully taken,
the Company shall issue and the Trustee shall authenticate a replacement
Security if the requirements of Section 8-405 of the Uniform Commercial Code are
met and the Holder satisfies any other reasonable requirements of the Trustee.
If required by the Trustee or the Company, such Holder shall furnish an
indemnity bond sufficient in the judgment of the Company and the Trustee to
protect the Company, the Trustee, the Paying Agent, the Registrar and any co-
registrar from any loss which any of them may suffer if a Security is replaced,
and, in the absence of notice to the Company or the Trustee that such Security
has been acquired by a protected purchaser, the Company shall execute and upon
Company Order the Trustee shall authenticate and make available for delivery, in
exchange for any such mutilated Security or in lieu of any such destroyed, lost
or stolen Security, a new Security of like tenor and principal amount, bearing a
number not contemporaneously outstanding.

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

               Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
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 and any other obligor upon the
Securities, whether or not the mutilated, destroyed, lost or stolen Security
shall be at any time enforceable by anyone, and shall be entitled to all
benefits of this Indenture equally and proportionately with any and all other
Securities duly issued hereunder.

                                                                              53


               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 2.10. Outstanding Securities. Securities outstanding at
any time are all Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation and those described in
this Section as not outstanding. A Security ceases to be outstanding in the
event the Company or a Subsidiary of the Company holds the Security, provided,
however, that (i) for purposes of determining which are outstanding for consent
or voting purposes hereunder, Securities shall cease to be outstanding in the
event the Company or an Affiliate of the Company holds the Security and (ii) in
determining whether the Trustee shall be protected in making a determination
whether the Holders of the requisite principal amount of outstanding Securities
are present at a meeting of Holders of Securities for quorum purposes or have
consented to or voted in favor of any request, demand, authorization, direction,
notice, consent, waiver, amendment or modification hereunder, or relying upon
any such quorum, consent or vote, only Securities which a Trust Officer of the
Trustee actually knows to be held by the Company or an Affiliate of the Company
shall not be considered outstanding.

               If a Security is replaced pursuant to Section 2.9, it ceases to
be outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a protected purchaser.

               If the Paying Agent segregates and holds in trust, in accordance
with this Indenture, on a redemption date or maturity date money sufficient to
pay all principal and interest payable on that date with respect to the
Securities (or portions thereof) to be redeemed or maturing, as the case may be,
and the Paying Agent is not prohibited from paying such money to the Holders on
that date pursuant to the terms of this Indenture, then on and after that date
such Securities (or portions thereof) cease to be outstanding and interest on
them ceases to accrue.

               SECTION 2.11. Temporary Securities. Until definitive Securities
are ready for delivery, the Company may prepare and the Trustee shall
authenticate temporary Securities. Temporary Securities shall be substantially
in the form of Definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate Definitive Securities.
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 maintained by the Company for that purpose
and such exchange shall be 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 make available for delivery in exchange
therefor, one or more Definitive Securities representing an equal principal
amount of Securities. Until so exchanged, the Holder of temporary Securities
shall in all respects be entitled to the same benefits under this Indenture as a
holder of Definitive Securities.

                                                                              54


               SECTION 2.12. Cancellation. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment or
cancellation and dispose of such Securities in accordance with its internal
policies including, if requested in writing by the Company, delivery of a
certificate of destruction describing such Securities. The Company may not issue
new Securities to replace Securities it has paid or delivered to the Trustee for
cancellation for any reason other than in connection with a registration of
transfer or exchange.

               SECTION 2.13. Payment of Interest; Defaulted Interest. 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 such
Security (or one or more predecessor Securities) is registered at the close of
business on the regular record date for such interest at the office or agency of
the Company maintained for such purpose pursuant to Section 2.3.

               Any interest on any Security which is payable, but is not paid
when the same becomes due and payable and such nonpayment continues for a period
of 30 days shall forthwith cease to be payable to the Holder on the regular
record date by virtue of having been such Holder, and such defaulted interest
and (to the extent lawful) interest on such defaulted interest at the rate borne
by the Securities (such defaulted interest and interest thereon herein
collectively called "Defaulted Interest") shall be paid by the Company, at its
election in each case, as provided in clause (a) or (b) below:

               (a) 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 (as defined below) 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 (not
       less than 30 days after such notice) of the proposed payment (the
       "Special Interest Payment Date"), 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 record date
       (the "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 Special Interest Payment Date 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
       and Special Interest Payment Date therefor to be given in the manner
       provided for in Section 13.2, 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 and Special Interest Payment Date therefor


<PAGE>   61

                                                                              55


       having been so given, such Defaulted Interest shall be paid on the
       Special Interest Payment Date 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 (b).

               (b) 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.

               SECTION 2.14. Computation of Interest. Interest on the Securities
shall be computed on the basis of a 360-day year of twelve 30-day months.

               SECTION 2.15. CUSIP Numbers. The Company in issuing the
Securities may use "CUSIP" numbers (if then generally in use) and, if so, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such CUSIP numbers. The Company shall promptly notify the Trustee of
any change in the CUSIP numbers.

               In the event that the Company shall issue and the Trustee shall
authenticate any Subsequent Series Securities pursuant to the third paragraph of
Section 2.2, the Company shall use its best efforts to obtain the same CUSIP
number for such Subsequent Series Securities as is printed on the Securities
outstanding at such time; provided, however, that if any series of Subsequent
Series Securities is determined, pursuant to an Opinion of Counsel, to be a
different class of security than the Securities outstanding at such time for
federal income tax purposes, the Company may obtain a CUSIP number for such
series of Subsequent Series Securities that is different from the CUSIP number
printed on the Securities then outstanding.

                                   ARTICLE III

                                    Covenants

               SECTION 3.1. Payment of Securities. The Company shall promptly
pay the principal of and interest on the Securities on the dates and in the
manner provided in the Securities and in this


<PAGE>   62

                                                                              56


Indenture. Principal and interest shall be considered paid on the date due if on
such date the Trustee or the Paying Agent holds in accordance with this
Indenture money sufficient to pay all principal and interest then due and the
Trustee or the Paying Agent, as the case may be, is not prohibited from paying
such money to the Holders on that date pursuant to the terms of this Indenture.

               The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

               Notwithstanding anything to the contrary contained in this
Indenture, the Company may, to the extent it is required to do so by law, deduct
or withhold income or other similar taxes imposed by the United States of
America from principal or interest payments hereunder.

               SECTION 3.2. SEC Reports and Available Information.
Notwithstanding that the Company may not be subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, to the extent permitted
by the Exchange Act, the Company will file with the SEC, and provide the Trustee
and the Holders of the Securities with, the annual reports and the information,
documents and other reports (or copies of such portions of any of the foregoing
as the SEC may by rules and regulations prescribe) that are specified in
Sections 13 and 15(d) of the Exchange Act within the time periods specified
therein. In the event that the Company is not permitted to file such reports,
documents and information with the SEC pursuant to the Exchange Act, the Company
will nevertheless provide such Exchange Act information to the Trustee and the
Holders of the Securities as if the Company were subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act within the time periods
specified therein. The Company shall also comply with the other provisions of
TIA Section 314(a). Delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee's receipt of such
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

               SECTION 3.3. Limitation on Indebtedness (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, Incur any
Indebtedness; provided, however, that the Company may Incur Indebtedness if on
the date thereof the Consolidated Coverage Ratio for the Company and its
Restricted Subsidiaries is at least 2.50 to 1.00.

               (b) Section 3.3(a) will not prohibit the incurrence of the
following Indebtedness: (1) Indebtedness Incurred pursuant to the Senior Credit
Agreement, including any amendment, modification, supplement, extension,
restatement, replacement (including replacement after the termination of such
Senior Credit Agreement), restructuring, increase, renewal, or refinancing
thereof from time to time in one or more agreements or instruments; provided,
however, that, after giving effect to any such Incurrence, the aggregate
principal amount of such Indebtedness then outstanding does not exceed the
greater of (i) $250 million and (ii) an amount equal to the sum of (A) $100.0
million and (B)


<PAGE>   63

                                                                              57


20% of Adjusted Consolidated Net Tangible Assets determined as of the date of
the Incurrence of such Indebtedness; (2) Indebtedness owed to and held by the
Company or a Restricted Subsidiary; provided, however, that any subsequent
issuance or transfer of any Capital Stock which results in any such Restricted
Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of
such Indebtedness (other than to the Company or a Restricted Subsidiary) shall
be deemed, in each case, to constitute the Incurrence of such Indebtedness by
the obligor thereon; (3) the Original Securities and any Exchange Securities or
Private Exchange Securities exchanged for such Original Securities; (4)
Indebtedness of the Company and any Restricted Subsidiary outstanding on the
Issue Date; (5) Indebtedness of a Restricted Subsidiary Incurred and outstanding
on or prior to the date on which such Subsidiary was acquired by the Company
(other than Indebtedness Incurred in connection with, or to provide all or any
portion of the funds or credit support utilized to consummate, the transaction
or series of related transactions pursuant to which such Subsidiary became a
Subsidiary or was acquired by the Company); provided, however, that at the time
such Restricted Subsidiary is acquired by the Company, the Company would have
been able to Incur $1.00 of additional Indebtedness pursuant to Section 3.3(a)
after giving effect to the Incurrence of such Indebtedness pursuant to this
clause (5); (6) Refinancing Indebtedness in respect of Indebtedness Incurred
pursuant to Section 3.3(a) or pursuant to clauses (3), (4), (5) of this Section
3.3(b) or this clause (6); (7) Hedging Obligations of the Company or any
Restricted Subsidiary consisting of Interest Rate Agreements directly related to
Indebtedness permitted to be Incurred pursuant to this Indenture; (8)
Non-Recourse Debt of any Unrestricted Subsidiary; (9) Indebtedness in respect of
bid, performance, reimbursement or surety obligations issued by or for the
account of the Company or any Restricted Subsidiary in the ordinary course of
business, including Guarantees and letters of credit functioning as or
supporting such bid, performance, reimbursement or surety obligations (in each
case other than for an obligation for money borrowed); (10) Indebtedness of the
Company or any Restricted Subsidiary consisting of obligations in respect of
purchase price adjustments, indemnities or Guarantees of the same or similar
matters in connection with the acquisition or disposition of Property; (11)
Indebtedness of the Company or any Restricted Subsidiary under Commodity
Agreements and Currency Agreements entered into in the ordinary course of
business for the purpose of limiting risks that arise in the ordinary course of
business of the Company and its Restricted Subsidiaries; (12) Any Guarantee by
the Company or a Subsidiary of the Company of Indebtedness Incurred pursuant to
Section 3.3(a) or pursuant to clause (1), (2), (3), (4), (7), (9), (10), (11) or
(13) of this Section 3.3(b) or pursuant to clause (6) of this Section 3.3(b) to
the extent the Refinancing Indebtedness Incurred thereunder directly or
indirectly Refinances Indebtedness Incurred pursuant to Section 3.3(a) or
pursuant to clauses (3) or (4) of this Section 3.3(b); (13) Indebtedness in an
aggregate principal amount which, when taken together with all other
Indebtedness of the Company outstanding on the date of such Incurrence (other
than Indebtedness permitted by clauses (1) through (12) above and (14) below or
Section 3.3(a)) does not exceed $50 million (which amount may, but need not, be
incurred under the Senior Credit Agreement); and (14) Indebtedness incurred by a
Restricted Subsidiary in an aggregate principal amount which, taken together
with all other Indebtedness of Restricted Subsidiaries outstanding on the date
of such Incurrence, does not exceed $50 million (which amount may, but need not,
be Incurred under the Senior Credit Agreement).

                                                                              58


               (c) For purposes of determining compliance with this covenant, in
the event that an item of proposed Indebtedness meets the criteria of more than
one of the categories of Indebtedness described in Sections 3.3(a) and (b), the
Company may, in its sole discretion, (1) at the time the proposed Indebtedness
is incurred, classify all or a portion of that item of Indebtedness on the date
of its Incurrence under either Section 3.3(a) or under any category in Section
3.3(b), (2) reclassify at a later date all or a portion of that or any other
item of Indebtedness as being or having been Incurred in any manner that
complies with this covenant, and (3) elect to comply with this Section 3.3 and
the applicable definitions in any order.

               (d) The amount of Indebtedness of any Person at any date will be:
(1) the lesser of (A) the outstanding principal amount of all unconditional
obligations described above, as such amount would be reflected on a balance
sheet prepared in accordance with GAAP, and (B) the actual outstanding principal
amount of all such obligations; (2) the accreted value of that Indebtedness, in
the case of any Indebtedness issued with original issue discount; and (3)the
principal amount of that Indebtedness, together with any interest on that
Indebtedness that is more than 30 days past due, in the case of any other
Indebtedness.

               (e) Accrual of interest, accrual of dividends, the accretion of
accreted value, the payment of interest in the form of additional Indebtedness
and the payment of dividends in the form of additional shares of Preferred Stock
will not be deemed to be an incurrence of Indebtedness for purposes of this
Section 3.3.

               (f) In addition, the Company will not permit any of its
Unrestricted Subsidiaries to Incur any Indebtedness or issue any shares of
Disqualified Stock, other than Non-Recourse Debt. If at any time an Unrestricted
Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary
shall be deemed to be Incurred by a Restricted Subsidiary of the Company as of
such date (and, if such Indebtedness is not permitted to be Incurred as of such
date under this Section 3.3, the Company shall be in Default of this Section
3.3).

               (g) For purposes of determining compliance with any U.S.
dollar-denominated restriction on the Incurrence of Indebtedness, the U.S.
dollar-equivalent principal amount of Indebtedness denominated in a foreign
currency shall be calculated based on the relevant currency exchange rate in
effect on the date such Indebtedness was Incurred, in the case of term
Indebtedness, or first committed, in the case of revolving credit Indebtedness;
provided that if such Indebtedness is Incurred to refinance other Indebtedness
denominated in a foreign currency, and such refinancing would cause the
applicable U.S. dollar-dominated restriction to be exceeded if calculated at the
relevant currency exchange rate in effect on the date of such refinancing, such
U.S. dollar-dominated restriction shall be deemed not to have been exceeded so
long as the principal amount of such refinancing Indebtedness does not exceed
the principal amount of such Indebtedness being refinanced. Notwithstanding any
other provision of this Section 3.3, the maximum amount of Indebtedness that the
Company may Incur pursuant to this Section 3.3 shall not be deemed to be
exceeded solely as a result of fluctuations in the exchange rate of currencies.
The principal amount of any Indebtedness incurred to


<PAGE>   65

                                                                              59

refinance other Indebtedness, if Incurred in a different currency from the
Indebtedness being refinanced, shall be calculated based on the currency
exchange rate applicable to the currencies in which such Refinancing
Indebtedness is denominated that is in effect on the date of such refinancing.

               SECTION 3.4. Limitation on Restricted Payments.

               (a) The Company will not, and will not permit any of its
Restricted Subsidiaries, directly or indirectly, to: (1) declare or pay any
dividend or make any distribution on or in respect of its Capital Stock
(including any payment in connection with any merger or consolidation involving
the Company or any of its Restricted Subsidiaries) except: (i) dividends or
distributions payable in Capital Stock of the Company (other than Disqualified
Stock) or in options, warrants or other rights to purchase such Capital Stock of
the Company; and (ii) dividends or distributions payable to the Company or a
Restricted Subsidiary of the Company (and if such Restricted Subsidiary is not a
Wholly-Owned Subsidiary, to its other holders of common Capital Stock on a pro
rata basis); (2) purchase, redeem, retire or otherwise acquire or retire for
value any Capital Stock of the Company or any direct or indirect parent of the
Company held by Persons other than the Company or a Restricted Subsidiary of the
Company (other than in exchange for Capital Stock of the Company (other than
Disqualified Stock)); (3) purchase, repurchase, redeem, defease or otherwise
acquire or retire for value, prior to scheduled maturity, scheduled repayment or
scheduled sinking fund payment, any Subordinated Obligations (other than the
purchase, repurchase or other acquisition of Subordinated Obligations purchased
in anticipation of satisfying a sinking fund obligation, principal installment
or final maturity, in each case due within one year of the date of purchase,
repurchase or acquisition); or (4) make any Restricted Investment in any Person;
(any such dividend, distribution, purchase, redemption, repurchase, defeasance,
other acquisition, retirement or Restricted Investment referred to in clauses
(1) through (4) shall be referred to herein as a "Restricted Payment"), if at
the time the Company or such Restricted Subsidiary makes such Restricted
Payment:

               (A) a Default shall have occurred and be continuing (or would
       result therefrom); or

               (B) the Company is not able to incur an additional $1.00 of
       Indebtedness pursuant to Section 3.3(a) after giving effect to such
       Restricted Payment; or

               (C) the aggregate amount of such Restricted Payment and all other
       Restricted Payments declared or made subsequent to the Issue Date would
       exceed the sum of (without duplication): (i) 50% of Consolidated Net
       Income for the period (treated as one accounting period) from the
       beginning of the first fiscal quarter commencing after the date of this
       Indenture to the end of the most recent fiscal quarter ending prior to
       the date of such Restricted Payment for which financial statements are in
       existence (or, in case such Consolidated Net Income is a deficit, minus
       100% of such deficit); (ii) 100% of the aggregate Net Cash Proceeds, plus
       the fair market value of the assets less any related liabilities as
       determined by the Board of Directors of the Company in good faith (such
       determination to be accompanied by a fairness opinion or appraisal issued
       by an accounting, appraisal or investment banking firm of national

                                                                              60


       standing if such fair market value is estimated to exceed $50 million)
       received by the Company from the issue or sale of its Capital Stock
       (other than Disqualified Stock) (including, without limitation, in a
       merger, consolidation, acquisition of Property or any other form of
       transaction involving the issue or sale of its Capital Stock (other than
       Disqualified Stock)) or other capital contributions (including, without
       limitation, through the merger or consolidation of a Person with and into
       the Company not involving the issuance or delivery of securities or other
       consideration by the Company to the holders of such Person's Capital
       Stock) subsequent to the Issue Date (other than Net Cash Proceeds
       received from an issuance or sale of such Capital Stock to a Subsidiary
       of the Company or an employee stock ownership plan, option plan or
       similar trust to the extent such sale to an employee stock ownership
       plan, option plan or similar trust is financed by loans from or
       guaranteed by the Company or any Restricted Subsidiary unless such loans
       have been repaid with cash on or prior to the date of determination);
       (iii) the amount by which Indebtedness of the Company is reduced on the
       Company's balance sheet upon the conversion or exchange (other than by a
       Subsidiary of the Company) subsequent to the Issue Date of any
       Indebtedness of the Company for Capital Stock (other than Disqualified
       Stock) of the Company (less the amount of any cash, or the fair market

       Company or any Restricted Subsidiary in such Unrestricted Subsidiary,
       which amount in each case under this clause (iv) was included in the
       calculation of the amount of Restricted Payments; provided, however, that
       no amount will be included under this clause (iv) to the extent it is
       already included in Consolidated Net Income.

shall be delivered to the Trustee, such determination to be accompanied by a

an agreement referred to in clause (1) of this paragraph or this clause (2);
provided, however, that the encumbrances and restrictions with respect to such
Restricted Subsidiary contained in any such agreement or amendment are no less
favorable in any material respect to the Holders of the Securities than the
encumbrances and restrictions contained in such agreements referred to in clause
(1) of this paragraph on the Issue Date; (3) in the case of Section 3.5(a)(3),
any encumbrance or restriction: (A) that restricts in a customary manner the
subletting, assignment or transfer of any Property that is subject to a lease,
license, joint operating agreement, area of mutual interest agreement,

provisions restricting dispositions of real property interests set forth in any
reciprocal easement agreements of the Company or any Restricted Subsidiary; or
(D) arising or agreed to in the ordinary course of business and that does not,

the Board of Directors of the Company than the provisions relating to such
encumbrance or restriction contained in this Indenture.

               SECTION 3.6. Limitation on Sales of Assets and Subsidiary Stock.
(a) The Company will not, and will not permit any of its Restricted Subsidiaries
to, make any Asset Disposition unless: (1) the Company or such Restricted
Subsidiary receives consideration at the time of such Asset Disposition at least
equal to the fair market value, as determined in good faith by the Board of
Directors (including as to the value of all non-cash consideration), of the
shares and assets subject to such Asset Disposition; (2) at least 75% of the
consideration thereof received by the Company or such Restricted Subsidiary, as
the case may be, is in the form of cash or Cash Equivalents, Additional Assets

Directors acting in good faith, such determination to be accompanied by a
fairness opinion or appraisal issued by an accounting, appraisal or investment
banking firm of national standing if such fair market value is estimated to
exceed $50 million) other than Permitted Consideration, so long as the aggregate

                                                                              64


Consolidated Net Tangible Assets; and (3) an amount equal to 100% of the Net
Available Cash from such Asset Disposition is applied by the Company or such
Restricted Subsidiary, as the case may be: (A) first, to the extent the Company
or any Restricted Subsidiary, as the case may be, elects (or is required by the
terms of any Senior Indebtedness), to prepay, repay or purchase Senior
Indebtedness or Indebtedness (other than any Preferred Stock) of a Restricted
Subsidiary (in each case other than Indebtedness owed to the Company or an
Affiliate of the Company) within 360 days from the later of the date of such
Asset Disposition or the receipt of such Net Available Cash; provided, however,
that, in connection with any prepayment, repayment or purchase of Indebtedness
pursuant to this clause (a), the Company or such Restricted Subsidiary will
retire such Indebtedness and will cause the related commitment (if any) to be
permanently reduced in an amount equal to the principal amount so prepaid,
repaid or purchased; provided that, prior to such retirement, the Company or its
Restricted Subsidiaries may temporarily repay Senior Indebtedness with the Net
Available Cash; and (B) second, to the extent of the balance of such Net
Available Cash after application in accordance with clause (a), to the extent
the Company or such Restricted Subsidiary elects, to invest in Additional Assets
within 360 days from the later of the date of such Asset Disposition or the
receipt of such Net Available Cash; provided that, prior to such investment, the
Company or its Restricted Subsidiaries may temporarily repay Senior Indebtedness
with the Net Available Cash.

               (b) Any Net Available Cash from Asset Sales that are not applied
or invested as provided in Section 3.6(a) will be deemed to constitute "Excess
Proceeds." On the 361st day after the later of the Asset Disposition or the
receipt of the Net Available Cash, if the aggregate amount of Excess Proceeds
exceeds $10.0 million, the Company will be required to make an offer ("Asset
Sale Offer") to all holders of Securities and to the extent required by the
terms thereof, to all holders of other Senior Indebtedness outstanding with
similar provisions requiring the Company to make an offer to purchase such
Senior Indebtedness with the proceeds from any Asset Disposition ("Pari Passu
Securities"), to purchase the maximum principal amount of Securities and any
such Pari Passu Securities to which the Asset Sale Offer applies that may be
purchased out of the Excess Proceeds, at an offer price in cash in an amount
equal to 100% of the principal amount thereof (or the accreted value of any such
Pari Passu Securities, if they were issued at a discount) plus accrued and
unpaid interest to the date of purchase, in accordance with the procedures set
forth in this Indenture or the agreements governing the Pari Passu Securities,
as applicable. To the extent that the aggregate amount of Securities and Pari
Passu Securities so validly tendered and not properly withdrawn pursuant to an
Asset Sale Offer is less than the Excess Proceeds, the Company may use any
remaining Excess Proceeds for general corporate purposes, subject to the other
covenants contained in this Indenture. If the aggregate principal amount of
Securities surrendered by Holders thereof and other Pari Passu Securities (or
the accreted value of any such Pari Passu Securities, if they were issued at a
discount) surrendered by holders or lenders thereof, collectively, exceeds the
amount of Excess Proceeds, the Company shall select the Securities and Pari
Passu Securities to be purchased on a pro rata basis on the basis of the
aggregate principal amount of tendered Securities and Pari Passu Securities (or
the accreted value of any such Pari Passu Securities, if they were issued at a
discount). Upon completion of such Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero.

                                                                              65


               (c) (1) The Asset Sale Offer will remain open for a period of 20
Business Days following its commencement, except to the extent that a longer
period is required by applicable law (the "Asset Sale Offer Period"). No later
than five Business Days after the termination of the Asset Sale Offer Period
(the "Asset Sale Purchase Date"), the Company will purchase the principal amount
of Securities and Pari Passu Securities required to be purchased pursuant to
this covenant (the "Asset Sale Offer Amount") or, if less than the Asset Sale
Offer Amount has been so validly tendered, all Securities and Pari Passu
Securities validly tendered in response to the Asset Sale Offer.

               (2) If the Asset Sale Purchase Date is on or after an interest
record date and on or before the related interest payment date, any accrued and
unpaid interest will be paid to the Person in whose name a Security is
registered at the close of business on such record date, and no additional
interest will be payable to Holders who tender Securities pursuant to the Asset
Sale Offer.

               (3) On or before the Asset Sale Purchase Date, the Company will,
to the extent lawful, accept for payment, on a pro rata basis to the extent
necessary, the Asset Sale Offer Amount of Securities and Pari Passu Securities
or portions thereof so validly tendered and not properly withdrawn pursuant to
the Asset Sale Offer, or if less than the Asset Sale Offer Amount has been
validly tendered and not properly withdrawn, all Securities and Pari Passu
Securities so validly tendered and not properly withdrawn. The Company will
deliver to the Trustee an Officers' Certificate stating that such Securities or
portions thereof were accepted for payment by the Company in accordance with the
terms of this Section 3.6 and, in addition, the Company will deliver all
certificates and Securities required, if any, by the agreements governing the
Pari Passu Securities. The Company or the Paying Agent, as the case may be, will
promptly (but in any case not later than five Business Days after the
termination of the Asset Sale Offer Period) mail or deliver to each tendering
Holder of Securities or holder or lender of Pari Passu Securities, as the case
may be, an amount equal to the purchase price of the Securities or Pari Passu
Securities so validly tendered and not properly withdrawn by such Holder or
lender, as the case may be, and accepted by the Company for purchase, and the
Company will promptly issue a new Security, and the Trustee, upon delivery of an
Officers' Certificate from the Company will authenticate and mail or deliver
such new Security to such Holder, in a principal amount equal to any unpurchased
portion of the Security surrendered. In addition, the Company will take any and
all other actions required by the agreements governing the Pari Passu
Securities. Any Security not so accepted will be promptly mailed or delivered by
the Company to the Holder thereof. The Company will publicly announce the
results of the Asset Sale Offer on the Asset Sale Purchase Date.

               For the purposes of Section 3.6, the following will be deemed to
be cash:

       (1)     the assumption by the transferee of Indebtedness (other than
               Subordinated Obligations or Disqualified Stock) of the Company or
               Indebtedness (other than Preferred Stock) of any Restricted
               Subsidiary of the Company and the release of the Company or such
               Restricted Subsidiary from all liability on such Indebtedness in
               connection with such Asset Disposition (in which case the Company
               will, without further action, be deemed

                                                                              66

               to have applied such deemed cash to Indebtedness in accordance
               with Section 3.6(a)(3)(A) above); and

       (2)     securities, notes or other obligations received by the Company or
               any Restricted Subsidiary of the Company from the transferee that
               are promptly converted by the Company or such Restricted
               Subsidiary into cash.

               (d) The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Indenture. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 3.6, the Company will
comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Indenture by virtue thereof.

               SECTION 3.7. Limitation on Affiliate Transactions. (a) The
Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, enter into or conduct any transaction (including the
purchase, sale, lease or exchange of any property or the rendering of any
service) with any Affiliate of the Company (an "Affiliate Transaction") unless:
(1) the terms of such Affiliate Transaction are no less favorable to the Company
or such Restricted Subsidiary, as the case may be, in any material respect than
those that could be obtained in a comparable transaction at the time of such
transaction in arm's-length dealings with a Person who is not such an Affiliate;
(2) in the event such Affiliate Transaction involves an aggregate amount in
excess of $5.0 million, the terms of such transaction have been approved by a
majority of the members of the Board of Directors of the Company and by a
majority of the members of such Board having no personal stake in such
transaction, if any (and such majority or majorities, as the case may be,
determines that such Affiliate Transaction satisfies the criteria in Section
3.7(a)(1)); and (3) in the event such Affiliate Transaction involves an
aggregate amount in excess of $15.0 million, the Company has received a written
opinion from an independent investment banking firm of nationally recognized
standing that such Affiliate Transaction is not materially less favorable than
those that might reasonably have been obtained in a comparable transaction at
such time on an arms-length basis from a Person that is not an Affiliate.

               (b) Section 3.7(a) will not apply to: (1) any Restricted Payment
(other than a Restricted Investment) permitted to be made pursuant to Section
3.4; (2) any issuance of securities, or other payments, awards or grants in
cash, securities or otherwise pursuant to, or the funding of, employment
arrangements, stock options and stock ownership plans and other reasonable fees,
compensation, benefits and indemnities paid or entered into by the Company or
its Restricted Subsidiaries in the ordinary course of business to or with
officers, directors or employees of the Company and its Restricted Subsidiaries;
(3) loans or advances to officers, directors and employees in the ordinary
course of business of the Company or any of its Restricted Subsidiaries; (4) any
transaction (i) between the Company and a Restricted Subsidiary, (ii) between
the Company and a joint venture or similar entity which would constitute an
Affiliate Transaction solely because the Company or Restricted Subsidiary owns
an equity interest in or otherwise controls such Restricted

                                                                              67


Subsidiary, joint venture or similar entity or (iii) between Restricted
Subsidiaries or a Restricted Subsidiary and a joint venture or similar entity
described in this clause (4); (5) the payment of reasonable and customary fees
paid to, and indemnity provided on behalf of, officers, directors or employees
of the Company or any Restricted Subsidiary of the Company; (6) the performance
of obligations of the Company or any of its Restricted Subsidiaries under the
terms of any agreement to which the Company or any of its Restricted
Subsidiaries is a party on the Issue Date, as these agreements may be amended,
modified or supplemented from time to time; provided, however that any future
amendment, modification or supplement entered into after the Issue Date will be
permitted to the extent that its terms are not more disadvantageous to the
Holders of the Securities than the terms of the agreements in effect on the
Issue Date; (7) transactions with suppliers or purchasers or sellers of goods or
services, in each case in the ordinary course of business and otherwise in
compliance with the terms of this Indenture, which are fair to the Company or
its Restricted Subsidiaries, in the good faith determination of the Board of
Directors of the Company or the senior management thereof and are on terms
(taken as a whole) at least as favorable as might reasonably have been obtained
at such time from an unaffiliated party; and (8) commercially reasonable
payments by the Company or any of its Restricted Subsidiaries to Hicks, Muse &
Co. Partners, L.P. or its Affiliates made for any financial advisory, financing,
underwriting or placement services or in respect of other investment banking
activities, including, without limitation, in connection with acquisitions or
divestitures which payments are approved by a majority of the Board of Directors
of the Company in good faith.

Change of Control, each Holder will have the right to require the Company to

such Holder's Securities at a purchase price in cash equal to 101% of the
principal amount of the Securities plus accrued and unpaid interest, if any, to

record date to receive interest due on the relevant interest payment date).

               (b) Within 90 days following the date on which the Company

purchased by the Company. The Paying Agent shall promptly mail to each Holder of
Securities so tendered the Change of Control Payment for such Securities, and
the Trustee shall promptly authenticate and mail (or cause to be transferred by
book-entry) to each Holder a new Security equal in principal amount to any
unpurchased portion of the Securities surrendered, if any; provided that each
such new Security shall be in a principal amount of $1,000 or an integral
multiple thereof. The Company shall publicly announce the results of the Change
of Control Offer on, or as soon as practicable after, the Change of Control
Payment Date.

               (d) If the Change of Control Payment Date is on or after an
interest record date and on or before the related interest payment date, any
accrued and unpaid interest, if any, will be paid to the Person in whose name a
Security is registered, at the close on business or such record date, and no
additional interest will be payable to Holders who tender pursuant to the Change
of Control Offer.

               (e) The Company will not be required to make a Change of Control
Offer upon a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in this Section 3.8 applicable to a Change of Control
Offer made by the Company and purchases all Securities validly tendered and not
withdrawn under such Change of Control Offer.

               (f) The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section 3.8. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Indenture, the Company will comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations described in this Indenture by virtue thereof.

               SECTION 3.9. Limitation on Sale of Capital Stock of Restricted
Subsidiaries. The Company will not, and will not permit any Restricted
Subsidiary of the Company to, transfer, convey, sell, lease or otherwise dispose
of any Voting Stock of any Restricted Subsidiary or to issue any of the Voting
Stock of a Restricted Subsidiary (other than, if necessary, shares of its Voting
Stock constituting directors' qualifying shares) to any Person except: (1) to
the Company or a Wholly- Owned Subsidiary; or (2) in compliance with Section 3.6
and immediately after giving effect to such transfer, conveyance, sale, lease,
other disposition or issuance, such Restricted Subsidiary continues to be a
Restricted Subsidiary, or if such Restricted Subsidiary would no longer be a
Restricted Subsidiary, then the Investment would have been permitted to be made
under Section 3.4 as if made on the date of such transfer, conveyance, sale,
lease, other disposition or issuance.

               Notwithstanding the preceding paragraph, the Company may sell all
the Voting Stock of a Restricted Subsidiary as long as the Company complies with
the terms of Section 3.6.

               SECTION 3.10. Limitation on Liens. The Company will not, and will
not permit any of its Restricted Subsidiaries to, create or permit to exist any
Liens upon any Principal Property or any shares of stock or Indebtedness of any
Restricted Subsidiary that owns or leases any Principal Property (whether such
Principal Property, shares of stock or Indebtedness are now owned or hereafter
acquired) unless all payments due under this Indenture with respect to the
Securities are secured on an equal and ratable basis with the obligations so
secured until such time as such obligations are no longer secured by a Lien. The
preceding sentence will not require the Company to secure the Securities if the
Liens consist of either (1) Permitted Liens or (2) Liens securing indebtedness
described in Section 3.11(b) below.

               SECTION 3.11. Limitation on Sale/Leaseback Transactions. (a)
Neither the Company nor any of its Restricted Subsidiaries will enter into any
Sale/Leaseback Transaction with respect to any Principal Property unless either
(1) the Company or such Restricted Subsidiary would be entitled, pursuant to the
provisions of this Indenture, to incur Indebtedness secured by a Lien on the
property to be leased without equally and ratably securing the Securities
pursuant to Section 3.10 or (2) the Company, within six months after the
effective date of such transaction, applies to the voluntary defeasance or
retirement of its funded debt an amount equal to the Attributable Indebtedness
of such transaction.

               (b) Notwithstanding the foregoing limitations in Sections 3.10
and 3.11(a), the Company and its Restricted Subsidiaries may issue, assume, or
guarantee Indebtedness secured by a Lien without securing the Securities, or may
enter into Sale/Leaseback Transactions without defeasing or retiring funded
debt, or enter into a combination of such transactions, if the sum of the
principal amount of all such Indebtedness and the Attributable Indebtedness of
all such Sale/Leaseback Transactions does not at any time exceed 15% of Adjusted
Consolidated Net Tangible Assets.

               SECTION 3.12. Limitation on Lines of Business. The Company will
not, and will not permit any Restricted Subsidiary to, engage in any business
other than a Related Business.

                                                                              70


               SECTION 3.13. Maintenance of Office or Agency. The Company will
maintain in The City of New York, an office or agency where the Securities may
be presented or surrendered for payment, where, if applicable, the Securities
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The principal corporate trust office of the Trustee, or
if the Trustee's principal corporate trust office is not located in The City of
New York, any other office or agency maintained by the Trustee in The City of
New York (the "Corporate Trust Office"), shall be such office or agency of the
Company, unless the Company shall designate and maintain some other office or
agency for one or more of such purposes. The Company will give prompt written
notice to the Trustee of any change in the location of any 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 of 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 any such designation; 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 City of New York for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and any change in the location of any such other
office or agency.

               SECTION 3.14. Corporate Existence. Subject to Article IV, the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence and that of each Restricted
Subsidiary and the corporate rights (charter and statutory), licenses and
franchises of the Company and each Restricted Subsidiary; provided, however,
that the Company shall not be required to preserve any such existence (except
the Company), right, license or franchise if the Board of Directors of the
Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Company and each of its Restricted
Subsidiaries, taken as a whole, and that the loss thereof is not, and will not
be, disadvantageous in any material respect to the Holders, and provided,
further, the Company may merge in accordance with Section 4.1.

               SECTION 3.15. 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, (i) all material taxes, assessments and governmental charges levied
or imposed upon the Company or any Restricted Subsidiary or upon the income,
profits or Property of the Company or any Restricted Subsidiary and (ii) all
lawful claims for labor, materials and supplies, which, if unpaid, might by law
become a material liability or Lien upon the Property of the Company or any
Restricted Subsidiary; provided, however, that the Company shall not be required
to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith


<PAGE>   77

                                                                              71


by appropriate proceedings and for which appropriate reserves, if necessary (in
the good faith judgment of management of the Company), are being maintained in
accordance with GAAP or where the failure to effect such payment will not be
disadvantageous to the Holders.

               SECTION 3.16. Additional Amounts. All payments made by the
Company under or with respect to the Securities shall be made free and clear of
and without withholding or deduction for or on account of any present or future
tax, duty, levy, impost, assessment or other governmental charge (including
penalties, interest and other liabilities related thereto) (hereinafter "Taxes")
imposed or levied by or on behalf of the government of the Cayman Islands or any
political subdivision or any authority or agency therein or thereof having power
to tax, or within any other jurisdiction in which the Company is organized or is
otherwise resident for tax purposes or any jurisdiction from or through which
payment is made (each a "Relevant Taxing Jurisdiction"), unless the Company is
required to withhold or deduct Taxes by law or by the interpretation or
administration thereof.

       If any deduction or withholding for or on account of Taxes imposed by a
Relevant Taxing Jurisdiction shall at any time be required on any payment made
under or with respect to the Securities, the Company shall pay such additional
amounts ("Additional Amounts") as may be necessary to ensure that the net amount
received by each Holder or the Trustee, as the case may be, after such
withholding or deduction will equal the amount such Holder or the Trustee, as
the case may be, would have received if such Taxes had not been withheld or
deducted; provided, however, that no such Additional Amounts will be payable in
respect of (1) any Taxes that would not have been so imposed but for the
existence of any present or former connection between the relevant Holder (or
between a fiduciary, settlor, beneficiary, member or shareholder of, or
possessor of power over the relevant Holder, if the relevant Holder is an
estate, nominee, trust or corporation) and the Relevant Taxing Jurisdiction
(other than the mere receipt of such payment or the ownership or holding outside
of the Cayman Islands of such Security but including, without limitation, such
relevant Holder (or such fiduciary, settlor, beneficiary, member or shareholder
or possessor) being or having been a citizen or resident thereof or being or
having been present or engaged in a trade or business therein or having or
having had a permanent establishment therein); (2) any estate, inheritance,
gift, sales, excise, transfer, personal property tax or similar tax, assessment
or governmental charge; (3) any tax, assessment or other governmental charge
that is imposed or withheld by reason of the failure by the Holder or the
beneficial owner of the Security to comply with a request (x) to provide
information, documents or other evidence concerning the nationality, residence
or identity of the Holder or such beneficial owner or (y) to make and deliver
any declaration or other similar claim (other than a claim for refund of a tax,
assessment or other governmental charge withheld by the Company) or satisfy any
information or reporting requirements, which, in the case of (x) or (y), is
required or imposed by a statute, treaty, regulation or administrative practice
of the taxing jurisdiction as a precondition to exemption from all or part of
such tax, assessment or other governmental charge; (4) any tax, assessment or
other governmental charge that is payable otherwise than by withholding from
payment of principal of, premium, if any, or interest on such Security; or (5)
any tax, assessment or governmental charge that would not have been imposed but
for the presentation of a Security for payment in the Cayman Islands or any
political subdivision thereof or therein, unless such Security could not have
been presented elsewhere, nor will such


<PAGE>   78

                                                                              72


Additional Amounts be payable (x) if the payment could have been made without
such deduction or withholding if the beneficiary of the payment had presented
the Security for payment within 30 days after the date on which such payment or
such Security became due and payable or the date on which payment thereof is
duly provided for, whichever is later (except to the extent that the holder
would have been entitled to Additional Amounts had the Security been presented
on the last day of such 30-day period), (y) if, at the election of the relevant
Holder, the payment of principal of (or premium, if any, on) or interest on such
Security could have been made through another paying agent without such
deduction or withholding, or (z) with respect to any payment of principal of (or
premium, if any, on) or interest on such Security to any Holder who is a
fiduciary or partnership or limited liability company that is treated as a
partnership for U.S. federal income tax purposes or any Person other than the
sole beneficial owner of such payment, to the extent that a beneficiary or
settlor with respect to such fiduciary, a member of such a partnership or
limited liability company that is treated as a partnership for U.S. federal
income tax purposes or the beneficial owner of such payment would not have been
entitled to the Additional Amounts had such beneficiary, settlor, member or
beneficial owner been the actual holder of such Security.

       Upon request, the Company will provide the Trustee with official receipts
or other documentation satisfactory to the Trustee evidencing the payment of the
Taxes with respect to which Additional Amounts are paid.

       Whenever in this Indenture there is mentioned, in any context:

       (1)     the payment of principal;

       (2)     purchase prices in connection with a purchase of Securities;

       (3)     interest; or

       (4)     any other amount payable on or with respect to any of the
               Securities,

such reference shall be deemed to include payment of Additional Amounts as
described under this Section 3.16 to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof.

       The Company shall pay any present or future stamp, court or documentary
taxes or any other excise or property taxes, charges or similar levies and other
duties (including interest and penalties) that arise in any jurisdiction from
the execution, delivery, enforcement or registration of the Securities, this
Indenture or any other document or instrument in relation thereof, or the
receipt of any payments with respect to the Securities, excluding such taxes,
charges or similar levies imposed by any jurisdiction outside of the Cayman
Islands or the United States (or any political subdivision or taxing authority
of either jurisdiction), the jurisdiction of incorporation of any successor of
the Company, any jurisdiction through which payment is made or in which a paying
agent is located or any jurisdiction in which the


<PAGE>   79

                                                                              73


Company is organized or engaged in business for tax purposes, and the Company
will agree to indemnify the Holders for any such taxes paid by such Holders.

       The obligations described under this Section 3.16 will survive any
termination, defeasance or discharge of this Indenture and will apply mutatis
mutandis to any jurisdiction in which any successor Person to the Company is
organized or any political subdivision or taxing authority or agency thereof or
therein.

               SECTION 3.17. Payments for Consent. Neither the Company nor any
of its Restricted Subsidiaries will, directly or indirectly, pay or cause to be
paid any consideration, whether by way of interest, fees or otherwise, to any
Holder of any Securities for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Securities
unless such consideration is offered to be paid or is paid to all Holders of the
Securities that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or agreement.

               SECTION 3.18. Compliance Certificate. The Company shall deliver
to the Trustee within 120 days after the end of each Fiscal Year of the Company
an Officers' Certificate signed by the Company's chief executive officer, chief
financial officer or chief accounting officer stating that in the course of the
performance by the signers of their duties as Officers of the Company they would
normally have knowledge of any Default or Event of Default and whether or not
the signers know of any Default or Event of Default that occurred during such
period. If they do, the certificate shall describe the Default or Event of
Default, its status and what action the Company is taking or proposes to take
with respect thereto. The Company also shall comply with TIA Section 314(a)(4).

               SECTION 3.19. Further Instruments and Acts. Upon request of the
Trustee, the Company will execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

               SECTION 3.20. Statement by Officers as to Default. The Company
shall deliver to the Trustee, as soon as possible and in any event within 30
days after the Company becomes aware of the occurrence of any Default of 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.

               SECTION 3.21. Effectiveness of Covenants. The Company and the
Restricted Subsidiaries will not be subject to the provisions of Sections 3.2,
3.3, 3.4, 3.5, 3.6, 3.7, 3.9, 3.12, 3.17 and 4.1(3) (together, the "Suspended
Covenants") during any period in which the Securities have an Investment Grade
Rating; provided, however, that if, at the time the Securities receive such an
Investment Grade Rating, a Default or Event of Default has occurred and is
continuing under this Indenture, the Suspended Covenants will continue to apply
to the Company and the Restricted Subsidiaries until such time that no Default
or Event of Default is continuing. In the event an Investment

                                                                              74


Grade Rating assigned to the Securities is withdrawn by either or both of the
Rating Agencies, such that the Securities do not have an Investment Grade Rating
from either Rating Agency, the Company and the Restricted Subsidiaries will
immediately upon such an occurrence be subject to the provisions of the
Suspended Covenants and any Restricted Payments made after such an Investment
Grade Rating is withdrawn will be calculated in accordance with Section 3.4 as
though such covenant had been in effect at all times since the Issue Date.

                                   ARTICLE IV

                                Successor Company

               SECTION 4.1. Merger and Consolidation. The Company shall not
consolidate with or merge with or into, or convey, transfer or lease all or
substantially all its assets to, any Person, unless:

               (1) the resulting, surviving or transferee Person, if other than
       the Company (the "Successor Company"), will be a corporation,
       partnership, trust or limited liability company organized and existing
       under the laws of the United States of America, any State thereof or the
       District of Columbia or the Cayman Islands and the Successor Company (if
       not the Company) will expressly assume, by supplemental indenture,
       executed and delivered to the Trustee, in form reasonably satisfactory to
       the Trustee, all the obligations of the Company under the Securities and
       this Indenture;

               (2) immediately after giving effect to such transaction (and
       treating any Indebtedness that becomes an obligation of the Successor
       Company or any Subsidiary of the Successor Company as a result of such
       transaction as having been Incurred by the Successor Company or such
       Subsidiary at the time of such transaction), no Default or Event of
       Default shall have occurred and be continuing;

               (3) immediately after giving effect to such transaction, either
       (a) the Successor Company would be able to Incur at least an additional
       $1.00 of Indebtedness pursuant to Section 3.3(a) or (b) the Consolidated
       Coverage Ratio for the Successor Company would not be less than the
       Consolidated Coverage Ratio of the Company immediately prior to the
       transaction; and

               (4) the Company shall have delivered to the Trustee an Officers'
       Certificate and an Opinion of Counsel, each stating that such
       consolidation, merger or transfer and such supplemental indenture (if
       any) comply with this Indenture.

               For purposes of this Section 4.1, the sale, lease, conveyance,
assignment, transfer, or other disposition of all or substantially all of the
properties and assets of one or more Restricted Subsidiaries of the Company,
which properties and assets, if held by the Company instead of such


<PAGE>   81

                                                                              75

Restricted Subsidiaries, would constitute all or substantially all of the
properties and assets of the Company and its Restricted Subsidiaries on a
consolidated basis, shall be deemed to be the transfer of all or substantially
all of the properties and assets of the Company.

               The Successor Company will succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Indenture,
but, in the case of a lease of all or substantially all its assets, the Company
will not be released from the obligation to pay the principal of and interest on
the Securities.

               Notwithstanding the preceding clause (3), (x) any Restricted
Subsidiary of the Company may consolidate with, merge into or transfer all or
part of its properties and assets to the Company and the Company may consolidate
with, merge into or transfer all or part of its properties and assets to any
Restricted Subsidiary and (y) the Company may merge with an Affiliate
incorporated solely for the purpose of reincorporating the Company in another
jurisdiction to realize tax or other benefits.

                                    ARTICLE V

                            Redemption of Securities

               SECTION 5.1. Optional Redemption. The Securities may be redeemed,
as a whole or from time to time in part, subject to the conditions and at the
redemption prices specified in the form of Securities set forth in Exhibits A
and B hereto, which are hereby incorporated by reference and made a part of this
Indenture, together with accrued and unpaid interest to the Redemption Date.

               SECTION 5.2. Applicability of Article. Redemption of Securities
at the election of the Company or otherwise, as permitted or required by any
provision of this Indenture, shall be made in accordance with such provision and
this Article.

               SECTION 5.3. Election to Redeem; Notice to Trustee. The election
of the Company to redeem any Securities pursuant to Section 5.1 shall be
evidenced by a resolution of the Company's Board of Directors. In case of any
redemption at the election of the Company, the Company shall, upon not later
than the earlier of the date that is 30 days prior to the Redemption Date fixed
by the Company or the date on which notice is given to the Holders (except as
provided in Section 5.5 or unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and of the principal amount
of Securities to be redeemed and shall deliver to the Trustee such documentation
and records as shall enable the Trustee to select the Securities to be redeemed
pursuant to Section 5.4.

               SECTION 5.4. Selection by Trustee of Securities to Be Redeemed.
If less than all the Securities are to be redeemed at any time pursuant to an
optional redemption, the particular Securities


<PAGE>   82

                                                                              76


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, in compliance with the requirements of the principal securities
exchange, if any, on which such Securities are listed, or, if such Securities
are not so listed, on a pro rata basis, by lot or by such other method as the
Trustee shall deem fair and appropriate (and in such manner as complies with
applicable legal requirements) and which may provide for the selection for
redemption of portions of the principal of the Securities; provided, however,
that no such partial redemption shall reduce the portion of the principal amount
of a Security not redeemed to less than $1,000.

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

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

               SECTION 5.5. Notice of Redemption. Notice of redemption shall be
given in the manner provided for in Section 10.2 not less than 30 nor more than
60 days prior to the Redemption Date, to each Holder of Securities to be
redeemed. The Trustee shall give notice of redemption in the Company's name and
at the Company's expense; provided, however, that the Company shall deliver to
the Trustee, at least 45 days prior to the Redemption Date, an Officers'
Certificate requesting that the Trustee give such notice and setting forth the
information to be stated in such notice as provided in the following items.

               All notices of redemption shall state:

               (1) the Redemption Date,

               (2) the redemption price and the amount of accrued interest to
       the Redemption Date payable as provided in Section 5.7, if any,

               (3) if less than all outstanding Securities are to be redeemed,
       the identification of the particular Securities (or portion thereof) to
       be redeemed, as well as the aggregate principal amount of Securities to
       be redeemed and the aggregate principal amount of Securities to be
       outstanding after such partial redemption,

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


<PAGE>   83

                                                                              77

               (5) that on the Redemption Date the redemption price (and accrued
       interest, if any, to the Redemption Date payable as provided in Section
       5.7) will become due and payable upon each such Security, or the portion
       thereof, to be redeemed, and, unless the Company defaults in making the
       redemption payment, that interest on Securities called for redemption (or
       the portion thereof) will cease to accrue on and after said date,

               (6) the place or places where such Securities are to be
       surrendered for payment of the redemption price and accrued interest, if
       any,

               (7) the name and address of the Paying Agent,

               (8) that Securities called for redemption must be surrendered to
       the Paying Agent to collect the redemption price,

               (9) the CUSIP number, and that no representation is made as to
       the accuracy or correctness of the CUSIP number, if any, listed in such
       notice or printed on the Securities, and

               (10) the paragraph of the Securities pursuant to which the
       Securities are to be redeemed.

               SECTION 5.6. Deposit of Redemption Price. Prior to 10:00 am (New
York City time) on 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 2.4) an amount of
money sufficient to pay the redemption price of, and accrued interest on, all
the Securities which are to be redeemed on that date.

               SECTION 5.7. 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 (together with accrued interest, if any, to the Redemption
Date), 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, if any, to the Redemption Date
(subject to the rights of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date).

               If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Securities.

               SECTION 5.8. Securities Redeemed in Part.

               Any Security which is to be redeemed only in part (pursuant to
the provisions of this Article) shall be surrendered at the office or agency of
the Company maintained for such purpose pursuant to Section 3.13 (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 such Holder's attorney duly authorized in writing),
and the Company shall execute, and the Trustee shall authenticate and make
available for delivery to the Holder of such Security at the expense of the
Company, a new Security or Securities, of any authorized denomination as
requested by such Holder, in an aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered, provided, that each such new Security will be in a principal amount
of $1,000 or integral multiple thereof.

                                   ARTICLE VI

                              Defaults and Remedies

               SECTION 6.1. Events of Default. An "Event of Default" occurs if:

               (1) the Company defaults in any payment of interest or additional
       interest (as required by the Exchange and Registration Rights Agreement)
       on any Security when the same becomes due and payable, and such default
       continues for a period of 30 days;

               (2) the Company defaults in the payment of the principal or
       premium, if any, of any Security when the same becomes due and payable at
       its Stated Maturity, upon optional redemption, upon required repurchase,
       upon declaration or otherwise;

               (3) the Company fails to comply with Article IV of this
       Indenture;

               (4) the Company fails to comply with any of Sections 3.2 through
       3.17 inclusive (in each case other than a failure to repurchase
       Securities when required pursuant to Section 3.6 or 3.8, which failure
       shall constitute an Event of Default under Section 6.1(2) and other than
       a failure to comply with Article IV, which failure shall constitute an
       Event of Default under Section 6.1(3)) and such failure continues for 30
       days after the notice specified below (with such notice only given after
       the expiry of the periods permitted to perform an obligation);

               (5) the Company defaults in the performance of or a breach by the
       Company of any other covenant or agreement in this Indenture or under the
       Securities (other than those referred to in (1), (2), (3) or (4) above)
       and such default continues for 60 days after the notice specified below
       (with such notice only given after the expiry of the periods permitted to
       perform an obligation);


<PAGE>   85

                                                                              79


       (6) there is a default under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries), other than Indebtedness owed to the Company or a
Restricted Subsidiary, whether such Indebtedness or guarantee now exists, or is
created after the date of this Indenture, which default (a) is caused by a
failure to pay principal of, or interest or premium, if any, on such
Indebtedness before the expiration of the grace period provided in such
Indebtedness ("Payment Default") or (b) results in the acceleration of such
Indebtedness prior to its maturity (the "cross acceleration provision") and, in
each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$15.0 million or more or its foreign currency equivalent at the time;

       (7) the Company or any Significant Subsidiary or a group of Restricted
Subsidiaries that, taken together (as of the latest audited consolidated
financial statements for the Company and its Restricted Subsidiaries), would
constitute a Significant Subsidiary, pursuant to or within the meaning of any
Bankruptcy Law (as defined below):

               (A) commences a voluntary case;

               (B) consents to the entry of an order for relief against it in an
       involuntary case;

               (C) consents to the appointment of a Custodian (as defined below)
       of it or for any substantial part of its Property; or

               (D) makes a general assignment for the benefit of its creditors;

or takes any comparable action under any foreign laws relating to insolvency;

       (8) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that:

               (A) is for relief against the Company or any Significant
       Subsidiary or any group of Restricted Subsidiaries that, taken together
       (as of the latest audited consolidated financial statements for the
       Company and its Restricted Subsidiaries) would constitute a Significant
       Subsidiary in an involuntary case;

               (B) appoints a Custodian of the Company or any Significant
       Subsidiary or any group of Restricted Subsidiaries that, taken together
       (as of the latest audited consolidated financial statements for the
       Company and its Restricted Subsidiaries) would constitute a Significant
       Subsidiary or for any substantial part of their property; or


<PAGE>   86

                                                                              80


                      (C) orders the winding up or liquidation of the Company or
               any Significant Subsidiary or any group of Restricted
               Subsidiaries that, taken together (as of the latest audited
               consolidated financial statements for the Company and its
               Restricted Subsidiaries) would constitute a Significant
               Subsidiary;

       or any similar relief is granted under any foreign laws and the order,
       decree or relief remains unstayed and in effect for 60 days; or

               (9) the Company or any Significant Subsidiary or group of
       Restricted Subsidiaries that, taken together (as of the latest audited
       consolidated financial statements for the Company and its Restricted
       Subsidiaries) would constitute a Significant Subsidiary, fails to pay
       final and non-appealable judgments in an aggregate principal amount in
       excess of $15.0 million or its foreign currency equivalent at the time
       (net of any amounts with respect to which a reputable and creditworthy
       insurance company has acknowledged liability in writing), which judgments
       are not paid, discharged or stayed for a period of 60 days after becoming
       final and non-appealable.

               The foregoing will constitute Events of Default whatever the
reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body.

               The term "Bankruptcy Law" means Title 11, United States Code, or
any similar Federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

               Notwithstanding the foregoing, a Default under clause (4) or (5)
of this Section 6.1 will not constitute an Event of Default until the Trustee or
the Holders of at least 25% in principal amount of the outstanding Securities
notify the Company of the Default and the Company does not cure such Default
within the time specified in said clause (4) or (5) after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default".

               SECTION 6.2. Acceleration. If an Event of Default (other than an
Event of Default specified in Section 6.1(7) or (8)) occurs and is continuing,
the Trustee by notice to the Company, or the Holders of at least 25% in
outstanding principal amount of the Securities by notice to the Company and the
Trustee, may, and the Trustee at the request of such Holders shall, declare the
principal of, premium, if any, and accrued and unpaid interest, on all the
Securities to be due and payable. Upon such a declaration, such principal,
premium, if any, and accrued and unpaid interest shall be immediately due and
payable. In the event of a declaration of acceleration because an Event of
Default set forth in Section 6.1(6) above has occurred and is continuing, such
declaration of acceleration shall be automatically rescinded and annulled if the
event of default or payment default triggering such Event of Default pursuant to
Section 6.1(6) shall be remedied or cured by the Company and/or the relevant
Restricted Subsidiary or the holders of the relevant Indebtedness have rescinded
the declaration of


<PAGE>   87

                                                                              81


acceleration in respect of such Indebtedness within 20 days after the
declaration of acceleration with respect thereto and if (1) the annulment of the
acceleration of the Securities would not conflict with any judgment or decree of
a court of competent jurisdiction, (2) all existing Events of Default, other
than the nonpayment of principal, premium or interest on the Securities that has
become due solely because of such acceleration, have been cured or waived and
(3) the Company has paid the Trustee all amounts due pursuant to Section 7.7. If
an Event of Default specified in Section 6.1(7) or (8) occurs and is continuing,
the principal of, premium, if any, and accrued and unpaid interest on all the
Securities will become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. No such
rescission shall affect any subsequent Default or Event of Default or impair any
right consequent thereto.

               SECTION 6.3. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of (or premium, if any) or interest on the Securities or to enforce
the performance of any provision of the Securities or this Indenture.

               The Trustee may maintain a proceeding even if it does not possess
any of the Securities or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Holder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

               SECTION 6.4. Waiver of Past Defaults. Subject to Section 6.2, the
Holders of a majority in principal amount of the outstanding Securities by
notice to the Trustee may (a) waive, by their consent (including, without
limitation consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Securities), an existing Default or Event of Default and
its consequences except (i) a Default or Event of Default in the payment of the
principal of, or premium, if any, or interest on a Security or (ii) a Default or
Event of Default in respect of a provision that under Section 9.2 cannot be
amended without the consent of each Holder affected and (b) rescind any such
acceleration with respect to the Securities and its consequences if (1)
rescission would not conflict with any judgment or decree of a court of
competent jurisdiction, (2) all existing Events of Default, other than the
nonpayment of the principal of, premium, if any, and interest on the Securities
that have become due solely by such declaration of acceleration, have been cured
or waived and (3) the Company has paid the Trustee all amounts due pursuant to
Section 7.7. When a Default or Event of Default is waived, it is deemed cured,
but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any consequent right.

               SECTION 6.5. Control by Majority. The Holders of a majority in
principal amount of the outstanding Securities may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Sections 7.1 and 7.2, that the Trustee determines is unduly
prejudicial to the rights of other


<PAGE>   88

                                                                              82


Holders or would involve the Trustee in personal liability; provided, however,
that the Trustee may take any other action deemed proper by the Trustee that is
not inconsistent with such direction. Prior to taking any action hereunder, the
Trustee shall be entitled to indemnification or security satisfactory to it in
its sole discretion against all losses and expenses caused by taking or not
taking such action.

               SECTION 6.6. Limitation on Suits. Subject to Section 6.7, a
Holder may not pursue any remedy with respect to this Indenture or the
Securities unless:

               (1) such Holder gives to the Trustee written notice stating that
       an Event of Default is continuing;

               (2) the Holder(s) of at least 25% in outstanding principal amount
       of the Securities make a request to the Trustee to pursue the remedy;

               (3) such Holder or Holders offer to the Trustee reasonable
       security or indemnity against any loss, liability or expense;

               (4) the Trustee does not comply with the request within 60 days
       after receipt of the request and the offer of security or indemnity; and

               (5) the Holders of a majority in principal amount of the
       Securities do not give the Trustee a direction that, in the opinion of
       the Trustee, is inconsistent with such request during such 60-day period.

               A Holder may not use this Indenture to prejudice the rights of
another Holder or to obtain a preference or priority over another Holder.

               SECTION 6.7. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture (including, without
limitation, Section 6.6), the right of any Holder to receive payment of
principal of, premium (if any) or interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Securities, or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

               SECTION 6.8. Collection Suit by Trustee. If an Event of Default
specified in Section 6.1(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.7.

               SECTION 6.9. Trustee May File Proofs of Claim. The Trustee may
file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders allowed in
any judicial proceedings relative to the Company, its


<PAGE>   89

                                                                              83


Subsidiaries or its or their respective creditors or properties and, unless
prohibited by law or applicable regulations, may vote on behalf of the Holders
in any election of a trustee in bankruptcy or other Person performing similar
functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make 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 its counsel, and any other amounts due the Trustee under Section 7.7.

               SECTION 6.10. Priorities. If the Trustee collects any money or
property pursuant to this Article VI, it shall pay out the money or property in
the following order:

               FIRST: to the Trustee for amounts due under Section 7.7;

               SECOND: to Holders for amounts due and unpaid on the Securities
       for principal, premium, if any, and interest, ratably, without preference
       or priority of any kind, according to the amounts due and payable on the
       Securities for principal and interest, respectively; and

               THIRD: to the Company.

               The Trustee may fix a record date and payment date for any
payment to Holders pursuant to this Section. At least 15 days before such record
date, the Company shall mail to each Holder and the Trustee a notice that states
the record date, the payment date and amount to be paid.

               SECTION 6.11. 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 or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by the Company, a suit by a Holder pursuant to
Section 6.7 or a suit by Holders of more than 10% in outstanding principal
amount of the Securities.

                                   ARTICLE VII

                                     Trustee

               SECTION 7.1. Duties of Trustee. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs; provided that if an Event of
Default occurs and is continuing, the Trustee will be under no obligation to
exercise any of the rights or powers under


<PAGE>   90

                                                                              84

this Indenture at the request or direction of any of the Holders unless such
Holders have offered to the Trustee reasonable indemnity or security against
loss, liability or expense.

               (b) Except during the continuance of an Event of Default:

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

               (2) in the absence of bad faith on its part, the Trustee may
       conclusively rely, as to the truth of the statements and the correctness
       of the opinions expressed therein, upon certificates or opinions
       furnished to the Trustee and conforming to the requirements of this
       Indenture. However, in the case of any such certificates or opinions
       which by any provisions hereof are specifically required to be furnished
       to the Trustee, the Trustee shall examine such certificates and opinions
       to determine whether or not they conform on their face to the
       requirements of this Indenture (but need not confirm or investigate the
       accuracy of mathematical calculations or other facts stated therein).

               (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own wilful misconduct,
except that:

               (1) this paragraph does not limit the effect of paragraph (b) of
       this Section;

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

               (3) the Trustee shall not be liable with respect to any action it
       takes or omits to take in good faith in accordance with a direction
       received by it pursuant to Section 6.5.

               (d) Every provision of this Indenture that in any way relates to
the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.1.

               (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

               (f) Money held in trust by the Trustee need not be segregated
from other funds except to the extent required by law.

               (g) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the


<PAGE>   91

                                                                              85


exercise of any of its rights or powers, if it shall have reasonable grounds to
believe that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it.

               (h) 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 7.1 and to the provisions of the TIA.

               (i) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

               (j) 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 unless such Holders shall have offered to the Trustee
reasonable security or indemnity satisfactory to it against the costs, expenses
(including reasonable attorneys' fees and expenses) and liabilities that might
be incurred by it in compliance with such request or direction.

               (k) The Trustee shall not be charged with the knowledge of any
Default or Event of Default with respect to the Securities unless either (1) a
Trust Officer shall have actual knowledge of such Default or Event of Default or
(2) written notice of such Default or Event of Default shall have been given to
the Trustee by the Company or by any Holder of the Securities.

               SECTION 7.2. Rights of Trustee. Subject to Section 7.1, (a) The
Trustee may conclusively rely on any document (whether in its original or
facsimile form) reasonably believed by it to be genuine and to have been signed
or presented by the proper person. The Trustee need not investigate any fact or
matter stated in the document.

               (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate and/or an Opinion of Counsel. The Trustee shall
not be liable for any action it takes or omits to take in good faith in reliance
on an Officers' Certificate or Opinion of Counsel.

               (c) The Trustee may act through its attorneys and agents and
shall not be responsible for the misconduct or negligence of any agent appointed
with due care.

               (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers, unless the Trustee's conduct constitutes wilful misconduct or
negligence.

               (e) The Trustee may consult with counsel of its selection, and
the advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Securities shall be full and complete authorization and
protection from liability in respect to any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

               SECTION 7.3. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar
or co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

               SECTION 7.4. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Company's
use of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the sale of the Securities or in the Securities other than the
Trustee's certificate of authentication.

               SECTION 7.5. Notice of Defaults. If a Default or Event of Default
occurs and is continuing and if a Trust Officer has actual knowledge thereof,
the Trustee shall mail to each Holder notice of the Default or Event of Default
within 90 days after it occurs. Except in the case of a Default or Event of
Default in payment of principal of, premium (if any), or interest on any
Security (including payments pursuant to the optional redemption or required
repurchase provisions of such Security, if any), the Trustee may withhold the
notice if and so long as its board of directors, a committee of its board of
directors or a committee of its trust officers in good faith determines that
withholding the notice is in the interests of the Holders.

               SECTION 7.6. Reports by Trustee to Holders. As promptly as
practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 15 in each year, the Trustee
shall mail to each Holder a brief report dated as of such May 15 that complies
with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b).
The Trustee shall also transmit by mail all reports required by TIA Section
313(c).

               A copy of each report at the time of its mailing to Holders shall
be filed with the SEC and each stock exchange (if any) on which the Securities
are listed. The Company agrees to notify promptly the Trustee whenever the
Securities become listed on any stock exchange and of any delisting thereof.

               SECTION 7.7. Compensation and Indemnity. The Company shall pay to
the Trustee from time to time reasonable compensation for its acceptance of this
Indenture and services hereunder as the Company and the Trustee shall from time
to time agree in writing. The Trustee's compensation shall not be limited by any
law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred or made by it, including costs of collection, costs of preparing and
reviewing reports, certificates and other documents, costs of preparation and
mailing of notices to Holders and reasonable costs of counsel retained by the
Trustee in connection with the delivery of an Opinion of Counsel or otherwise,
in addition to the compensation for its services. Such expenses shall include
the reasonable compensation and expenses, disbursements and advances of the
Trustee's agents, counsel, accountants and experts. The Company

                                                                              87

shall indemnify the Trustee against any and all loss, liability, damages, claims
or expense (including reasonable attorneys' fees and expenses) incurred by it
without negligence or wilful misconduct on its part in connection with the
administration of this trust and the performance of its duties hereunder,
including the costs and expenses of enforcing this Indenture (including this
Section 7.7) and of defending itself against any claims (whether asserted by any
Holder, the Company or otherwise). The Trustee shall notify the Company promptly
of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder.
The Company shall defend the claim and the Trustee may have separate counsel and
the Company shall pay the fees and expenses of such counsel provided that the
Company shall not be required to pay such fees and expenses if it assumes the
Trustee's defense, and, in the reasonable judgment of outside counsel to the
Trustee, there is no conflict of interest between the Company and the Trustee in
connection with such defense. The Company need not reimburse any expense or
indemnify against any loss, liability or expense incurred by the Trustee through
the Trustee's own wilful misconduct or negligence.

               To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities. The Trustee's right to
receive payment of any amounts due under this Section 7.7 shall not be
subordinate to any other liability or Indebtedness of the Company.

               The Company's payment obligations pursuant to this Section shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.1(7) or (8) with respect to
the Company, the expenses are intended to constitute expenses of administration
under any Bankruptcy Law.

               The provisions of this Section 7.7 shall survive the resignation
or removal of the Trustee and the termination of this Indenture.

               SECTION 7.8. Replacement of Trustee. The Trustee may resign at
any time by so notifying the Company. The Holders of a majority in principal
amount of the Securities may remove the Trustee by so notifying the Trustee and
may appoint a successor Trustee. The Company shall remove the Trustee if:

               (1) the Trustee fails to comply with Section 7.10;

               (2) the Trustee is adjudged bankrupt or insolvent;

               (3) a receiver or other public officer takes charge of the
       Trustee or its property; or

               (4) the Trustee otherwise becomes incapable of acting.

                                                                              88


               If the Trustee resigns or is removed by the Company or by the
Holders of a majority in principal amount of the Securities and such Holders do
not reasonably promptly appoint a successor Trustee, or if a vacancy exists in
the office of the Trustee for any reason (the Trustee in such event being
referred to herein as the retiring Trustee), the Company shall promptly appoint
a successor Trustee.

               A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, subject to the lien provided for
in Section 7.7.

               If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee or the Holders
of 10% in principal amount of the Securities may petition, at the Company's
expense, any court of competent jurisdiction for the appointment of a successor
Trustee.

               If the Trustee fails to comply with Section 7.10, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

               Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.7 shall continue for the
benefit of the retiring Trustee.

               SECTION 7.9. Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

               In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture, any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

               SECTION 7.10. Eligibility; Disqualification. The Trustee shall at
all times satisfy the requirements of TIA Section 310(a). The Trustee shall have
a combined capital and surplus of at least $100 million as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
Section 310(b); provided, however, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or


<PAGE>   95

                                                                              89


participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in TIA Section 310(b)(1) are met.

               SECTION 7.11. Preferential Collection of Claims Against Company.
The Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated.

               SECTION 7.12. Trustee's Application for Instruction from the
Company. Any application by the Trustee for written instructions from the
Company may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or after which such action shall be taken or such omission shall be
effective. The Trustee shall not be liable for any action taken by, or omission
of, the Trustee in accordance with a proposal included in such application on or
after the date specified in such application (which date shall not be less than
three Business Days after the date any officer of the Company actually receives
such application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

                                  ARTICLE VIII

                       Discharge of Indenture; Defeasance

               SECTION 8.1. Discharge of Liability on Securities; Defeasance.
(a) Subject to Section 8.1(c), when (i)(x) the Company delivers to the Trustee
all outstanding Securities (other than Securities replaced pursuant to Section
2.9) for cancellation or (y) all outstanding Securities not theretofore
delivered for cancellation have become due and payable, whether at maturity or
upon redemption or will become due and payable within one year or 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 irrevocably deposits or causes to be
deposited with the Trustee as trust funds in trust solely for the benefit of the
Holders money in U.S. dollars, U.S. Government Obligations, or a combination
thereof, in such amounts (including principal and any interest payable on such
U.S. Government Obligations) as will be sufficient without consideration of any
reinvestment of interest to pay and discharge the entire indebtedness on such
Securities not theretofore delivered to the Trustee for cancellation for
principal, premium, if any, and accrued interest to the date of maturity or
redemption, (ii) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit or shall occur as a result of such
deposit and such deposit will not result in a breach or violation of, or
constitute a default under, any other instrument to which the Company is a party
or by which the Company is bound; (iii) the Company has paid or caused to be
paid all sums payable by it under this Indenture and the Securities; and (iv)
the Company has delivered irrevocable instructions to the Trustee under this
Indenture to apply the deposited money toward the payment of such Securities at
maturity or the Redemption Date, as the case may be, then


<PAGE>   96

                                                                              90


the Trustee shall acknowledge satisfaction and discharge of this Indenture on
demand of the Company (accompanied by an Officers' Certificate and an Opinion of
Counsel stating that all conditions precedent specified herein relating to the
satisfaction and discharge of this Indenture have been complied with) and at the
cost and expense of the Company.

               (b) Subject to Sections 8.1(c) and 8.2, the Company at any time
may terminate (i) all its obligations under the Securities and this Indenture
("legal defeasance option"), and after giving effect to such legal defeasance,
any omission to comply with such obligations shall no longer constitute a
Default or Event of Default or (ii) its obligations under Sections 3.2, 3.3,
3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.17, and 4.1(3) and the Company
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply with such covenants shall no
longer constitute a Default or an Event of Default under Section 6.1(3) and
6.1(4) and the operation of Sections 6.1(6), 6.1(7) (but only with respect to a
Significant Subsidiary), 6.1(8) (but only with respect to a Significant
Subsidiary) and 6.1(9), and the events specified in such Sections shall no
longer constitute an Event of Default (clauses (ii) being referred to as the
"covenant defeasance option"), but except as specified above, the remainder of
this Indenture and the Securities shall be unaffected thereby. The Company may
exercise its legal defeasance option notwithstanding its prior exercise of its
covenant defeasance option.

               If the Company exercises its legal defeasance option, payment of
the Securities may not be accelerated because of an Event of Default. If the
Company exercises its covenant defeasance option, payment of the Securities may
not be accelerated because of an Event of Default specified in Section 6.1(4)
(as such Section relates to 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11,
3.12, and 3.17), 6.1(6), 6.1(7) (but only with respect to a Significant
Subsidiary), 6.1(8) (but only with respect to a Significant Subsidiary), or
6.1(9) or because of the failure of the Company to comply with Section 4.1(3).

               Upon satisfaction of the conditions set forth herein and upon
request of the Company, the Trustee shall acknowledge in writing the discharge
of those obligations that the Company terminates.

               (c) Notwithstanding the provisions of Sections 8.1(a) and (b),
the Company's obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.9, 2.10, 2.11,
3.1, 3.13, 3.15, 3.16, 6.7, 7.7, 7.8 and in this Article 8 shall survive until
the Securities have been paid in full. Thereafter, the Company's obligations in
Sections 7.7, 8.4 and 8.5 shall survive.

                                                                              91


               SECTION 8.2. Conditions to Defeasance. The Company may exercise
its legal defeasance option or its covenant defeasance option only if:

               (1) the Company irrevocably deposits in trust with the Trustee
       for the benefit of the Holders money in U.S. dollars or U.S. Government
       Obligations or a combination thereof for the payment of principal,
       premium, if any, and interest on the Securities to maturity or
       redemption, as the case may be;

               (2) the Company delivers to the Trustee a certificate from a
       nationally recognized firm of independent accountants expressing their
       opinion that the payments of principal and interest when due and without
       reinvestment on the deposited U.S. Government Obligations plus any
       deposited money without investment will provide cash at such times and in
       such amounts as will be sufficient to pay principal and interest when due
       on all the Securities to maturity;

               (3) no Default or Event of Default shall have occurred and be
       continuing on the date of such deposit or, with respect to certain
       bankruptcy or insolvency Events of Default, on the 91st day after such
       date of deposit;

               (4) such legal defeasance or covenant defeasance shall not result
       in a breach or violation of, or constitute a Default under, this
       Indenture or any other material agreement or instrument to which the
       Company or any of its Restricted Subsidiaries is a party or by which the
       Company or any of its Subsidiaries is bound;

               (5) the Company shall have delivered to the Trustee an Opinion of
       Counsel (subject to customary assumptions and exclusions) to the effect
       that (A) the Securities and (B) assuming no intervening bankruptcy of the
       Company between the date of deposit and the 91st day following the
       deposit and that no Holder of the Securities is an insider of the
       Company, after the 91st day following the deposit, the trust funds will
       not be subject to the effect of any applicable bankruptcy, insolvency,
       reorganization or similar laws affecting creditors' right generally;

               (6) the deposit does not constitute a default under any other
       agreement binding on the Company;

               (7) the Company delivers to the Trustee an Opinion of Counsel
       (subject to customary assumptions and exclusions) to the effect that the
       trust resulting from the deposit does not constitute, or is qualified as,
       a regulated investment company under the Investment Company Act of 1940;

               (8) in the case of the legal defeasance option, the Company shall
       have delivered to the Trustee an Opinion of Counsel (subject to customary
       assumptions and exclusions) in the United States stating that (i) the
       Company has received from, or there has been published by, the Internal
       Revenue Service a ruling, or (ii) since the date of this Indenture there
       has been a change


<PAGE>   98

                                                                              92


       in the applicable federal income tax law, in either case to the effect
       that, and based thereon such Opinion of Counsel shall confirm that, the
       Holders will not recognize income, gain or loss for federal income tax
       purposes as a result of such defeasance and will be subject to federal
       income tax on the same amounts, in the same manner and at the same times
       as would have been the case if such legal defeasance had not occurred;

               (9) in the case of the covenant defeasance option, the Company
       shall have delivered to the Trustee an Opinion of Counsel (subject to
       customary assumptions and exclusions) in the United States to the effect
       that the Holders will not recognize income, gain or loss for federal
       income tax purposes as a result of such deposit and covenant defeasance
       and will be subject to federal income tax on the same amount, in the same
       manner and at the same times as would have been the case if such deposit
       and covenant defeasance had not occurred; and

               (10) the Company delivers to the Trustee an Officers' Certificate
       and an Opinion of Counsel, each stating that all conditions precedent to
       the defeasance and discharge of the Securities and this Indenture as
       contemplated by this Article VIII have been complied with.

               SECTION 8.3. Application of Trust Money. The Trustee shall hold
in trust money or U.S. Government Obligations deposited with it pursuant to this
Article VIII. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities.

               SECTION 8.4. Repayment to Company. The Trustee and the Paying
Agent shall promptly turn over to the Company upon request any excess money or
securities held by them upon payment of all the obligations under this
Indenture.

               Subject to any applicable abandoned property law, the Trustee and
the Paying Agent shall pay to the Company upon request any money held by them
for the payment of principal of or interest on the Securities that remains
unclaimed for two years, and, thereafter, Holders entitled to the money must
look to the Company for payment as general creditors.

               SECTION 8.5. Indemnity for U.S. Government Obligations. The
Company shall pay and shall indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against deposited U.S. Government Obligations or
the principal and interest received on such U.S. Government Obligations.

               SECTION 8.6. Reinstatement. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article VIII by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the obligations of the Company under
this Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article VIII until such time as the
Trustee or Paying Agent is permitted to apply all such money


<PAGE>   99

                                                                              93


or U.S. Government Obligations in accordance with this Article VIII; provided,
however, that, if the Company has made any payment of interest on or principal
of any Securities because of the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders of such Securities to receive
such payment from the money or U.S. Government Obligations held by the Trustee
or Paying Agent.

                                   ARTICLE IX

                                   Amendments

               SECTION 9.1. Without Consent of Holders. The Company and the
Trustee may amend this Indenture or the Securities without notice to or consent
of any Holder:

               (1) to cure any ambiguity, omission, defect or inconsistency;

               (2) to comply with Article IV in respect of the assumption by a
       Successor Company of an obligation of the Company under this Indenture;

               (3) to provide for uncertificated Securities in addition to or in
       place of certificated Securities; provided, however, that the
       uncertificated Securities are issued in registered form for purposes of
       Section 163(f) of the Code or in a manner such that the uncertificated
       Securities are described in Section 163(f)(2)(B) of the Code;

               (4) to add Guarantees with respect to the Securities or to secure
       the Securities;

               (5) to add to the covenants of the Company for the benefit of the
       Holders or to surrender any right or power herein conferred upon the
       Company;

               (6) to comply with any requirements of the SEC in connection with
       qualifying this Indenture under the TIA;

               (7) to make any change that does not adversely affect the rights
       of any Holder in any material respect; or

               (8) to provide for the issuance of the Exchange Securities, which
       will have terms substantially identical in all material respects to the
       Initial Securities (except that the transfer restrictions contained in
       the Initial Securities will be modified or eliminated, as appropriate),
       and which will be treated, together with any outstanding Initial
       Securities, as a single issue of securities.

                                                                              94


               After an amendment under this Section becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section.

               SECTION 9.2. With Consent of Holders. The Company and the Trustee
may amend this Indenture or the Securities without notice to any Holder but with
the written consent of the Holders of at least a majority in principal amount of
the Securities then outstanding (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer
for, Securities). However, without the consent of each Holder of an outstanding
security affected, an amendment may not:

               (1) reduce the amount of Securities whose Holders must consent to
       an amendment;

               (2) reduce the stated rate of or extend the stated time for
       payment of interest on any Security;

               (3) reduce the principal of or extend the Stated Maturity of any
       Security;

               (4) reduce the premium payable upon the redemption or repurchase
       of any Security or, after the Company's obligation to purchase the
       Securities arises under this Indenture, change the time at which any
       Security may or shall be redeemed or repurchased as described above under
       Section 3.6, Section 3.8 (including an amendment to the definition of
       "Change of Control") or Article V or any similar provision, whether
       through an amendment to or waiver of Section 3.6, Section 3.8 or Article
       V, a definition or otherwise;

               (5) make any Security payable in money other than that stated in
       the Security;

               (6) impair the right of any Holder to receive payment of
       principal of, premium, if any, and interest on such Holder's Securities
       on or after the due dates therefor or to institute suit for the
       enforcement of any payment on or with respect to such Holder's
       Securities; or

               (7) make any change to the amendment provisions which require
       each Holder's consent or to the waiver provisions.

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

               After an amendment under this Section becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section.

               SECTION 9.3. Compliance with Trust Indenture Act. Every amendment
to this Indenture or the Securities shall comply with the TIA as then in effect.

               SECTION 9.4. Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Holder. An amendment
or waiver shall become effective upon receipt by the Trustee of the requisite
number of written consents under Section 9.1 or 9.2 as applicable.

               The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall become valid or effective more than 120
days after such record date.

               SECTION 9.5. Notation on or Exchange of Securities. If an
amendment changes the terms of a Security, the Trustee may require the Holder of
the Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

               SECTION 9.6. Trustee To Sign Amendments. The Trustee shall sign
any amendment authorized pursuant to this Article IX if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Sections 7.1 and 7.2) shall be fully protected in
relying upon an Officers' Certificate and an Opinion of Counsel stating that
such amendment is authorized or permitted by this Indenture.

               (1) a statement that the individual making such certificate or
       opinion has read such covenant or condition;

               (2) a brief statement as to the nature and scope of the
       examination or investigation upon which the statements or opinions
       contained in such certificate or opinion are based;

               (3) a statement that, in the opinion of such individual, he has
       made such examination or investigation as is necessary to enable him to
       express an informed opinion as to whether or not such covenant or
       condition has been complied with; and

               (4) a statement as to whether or not, in the opinion of such

direction, waiver or consent, Securities owned by the Company or by any Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company shall be disregarded and deemed not to be
outstanding, except that, for the purpose of determining whether the Trustee

Registrar and the Paying Agent may make reasonable rules for their functions.

               SECTION 10.8. Legal Holidays. A "Legal Holiday" is a Saturday, a
Sunday or other day on which commercial banking institutions are authorized or

and no interest shall accrue for the intervening period. If a regular record
date is a Legal Holiday, the record date shall not be affected.

               SECTION 10.9. (a) GOVERNING LAW. THIS INDENTURE AND THE

Borough of Manhattan, New York City, New York, U.S.A., and any appellate court
from any thereof for the purpose of any legal action or proceeding in any such
court with respect to, or arising out of, this Agreement. The Company waives any
objection to proceedings in such courts whether on the grounds of venue,
residence or domicile or on the ground that the proceedings have been brought in
an inconvenient forum. The Company agrees that a final non-appealable judgment
in any such proceeding shall be conclusive and binding upon it and may be
enforced in any court referred to above or in any other courts to the
jurisdiction of which the Company is or may be subject, by a suit upon such
judgment.

               (c) The Company designates and appoints Triton Energy
Corporation, 6688 North Central Expressway, Suite 1400, Dallas, Texas
75206-9926, Attention: General Counsel, and its successors and assigns as the
Company's lawful agent in the United States upon which may be served, and which
may accept and acknowledge, for and on behalf of the Company all process in any
action, suit or proceedings that may be brought against the Company in any of
the courts referred to in this Section, and agrees that such service of process,
or the acceptance or acknowledgment thereof by said agent, shall be valid,
effective and binding in every respect; provided, however, that if said agency
shall cease for any reason whatsoever, the Company hereby designates and
appoints, without power of revocation, the Secretary of State of the State of
New York to serve as its agent for service of process.

               SECTION 10.10. No Recourse Against Others. An incorporator,
director, officer, employee, shareholder or controlling person, as such, of the
Company shall not have any liability for any obligations of the Company under
the Securities or this Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
Holder shall waive and release all such liability. The waiver and release shall
be part of the consideration for the issue of the Securities.

of Counsel or other documentation as it may reasonably request in connection

                   [FORM OF REVERSE SIDE OF INITIAL SECURITY]

                          8 7/8% Senior Notes due 2007

1.  Interest

               Triton Energy Limited, a Cayman Islands company (such company,
and its successors and assigns under the Indenture hereinafter referred to,
being herein called the "Company"), promises to pay interest on the principal
amount of this Security at the rate per annum shown above.

               The Company will pay interest semiannually on April 1 and October
1 of each year commencing April 1, 2001. Interest on the Securities will accrue
from the most recent date to which interest has been paid on the Securities or,
if no interest has been paid, from October 4, 2000. The Company shall pay
interest on overdue principal or premium, if any (plus interest on such interest
to the extent lawful), at the rate borne by the Securities to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

2.  Method of Payment

               By at least 10:00 a.m. (New York City time) on the date on which
any principal of or interest on any Security is due and payable, the Company
shall irrevocably deposit with the Trustee or the Paying Agent money sufficient
to pay such principal, premium, if any, and/or interest. The Company will pay
interest (except Defaulted Interest) to the Persons who are registered Holders
of Securities at the close of business on the March 15 and September 15
immediately next preceding the interest payment date even if Securities are
cancelled, repurchased or redeemed after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. Payments in respect of Securities represented by a
Global Security (including principal, premium, if any, and interest) will be
made by the transfer of immediately available funds to the accounts specified by
The Depository Trust Company. The Company will make all payments in respect of a
Definitive Security (including principal, premium, if any, and interest) by
mailing a check to the registered address of each Holder thereof; provided,
however, that payments on the Securities may also be made, in the case of a
Holder of a least $1,000,000 aggregate principal amount of Securities, by wire
transfer to a U.S. dollar account maintained by the payee with a bank in the
United States if such Holder elects payment by wire transfer by giving written
notice to the Trustee or the Paying Agent to such effect designating such
account no later than 15 days immediately preceding the relevant due date for
payment (or such other date as the Trustee may accept in its discretion).



                                      A-2
<PAGE>   109


3.  Paying Agent and Registrar

               Initially, The Chase Manhattan Bank (the "Trustee"), will act as
Trustee, Paying Agent and Registrar. The Company may appoint and change any
Paying Agent, Registrar or co-registrar without notice to any Holder. The
Company or any of its Restricted Subsidiaries may act as Paying Agent, Registrar
or co-registrar.

4.  Indenture

               The Company issued the Securities under an Indenture dated as of
October 4, 2000 (as it may be amended or supplemented from time to time in
accordance with the terms thereof, the "Indenture"), among the Company and the
Trustee. The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S.C. Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the
"Act"). Capitalized terms used herein and not defined herein have the meanings
ascribed thereto in the Indenture. The Securities are subject to all such terms,
and Holders are referred to the Indenture and the Act for a statement of those
terms.

               The Securities are general unsecured senior obligations of the
Company limited to $500.0 million aggregate principal amount (subject to Section
2.9 of the Indenture) which may be issued from time to time under the Indenture.
This Security is one of the Original Securities (also referred to as Initial
Securities) referred to in the Indenture. The Initial Securities, Private
Exchange Securities and the Exchange Securities will be treated as a single
class of securities under the Indenture. The Indenture imposes certain
limitations on, among other things: the Incurrence of Indebtedness by the
Company and its Restricted Subsidiaries, the purchase or redemption of Capital
Stock of the Company, certain purchases or redemptions of Subordinated
Obligations, the Incurrence of Liens by the Company or its Restricted
Subsidiaries, the sale or transfer of assets and Capital Stock of Restricted
Subsidiaries, the issuance or sale of Capital Stock of Restricted Subsidiaries,
the business activities and investments of the Company and its Restricted
Subsidiaries, mergers and consolidation, and transactions with Affiliates. In
addition, the Indenture limits the ability of the Company and its Restricted
Subsidiaries to restrict distributions and dividends from Restricted
Subsidiaries.

5.  Redemption

               Except as set forth below, the Securities will not be redeemable
until October 1, 2004. On and after such date, the Securities will be
redeemable, at the Company's option, in whole or in part, at any time upon not
less than 30 nor more than 60 days prior notice mailed by first-class mail to
each Holder's registered address, at the following redemption prices (expressed
in percentages of principal amount), plus accrued and unpaid interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date), if
redeemed during the 12-month period commencing on October 1 of the years set
forth below:

 2006 and thereafter                                                    100.000%
</TABLE>

               Prior to October 1, 2003, the Company may redeem in the aggregate
up to 35% of the original principal amount of the Securities with the Net Cash
Proceeds of one or more Equity Offerings received by the Company at a redemption
price (expressed as a percentage of principal amount) of 108.875% plus accrued
and unpaid interest, if any, to the redemption date (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date); provided, however, that (1) at least 65% of the
original principal amount of the Securities must remain outstanding after each
such redemption; and (2) that each such redemption occurs within 120 days of the
date of closing of such Equity Offering. Pending the application of the Net Cash
Proceeds of any Equity Offering to redeem Securities in accordance with the
provisions of this paragraph, the Company or its Restricted Subsidiaries may
temporarily repay Senior Indebtedness with those Net Cash Proceeds.

               In the case of any partial redemption, selection of the
Securities for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities are listed or, if the Securities are not listed, then on a pro rata
basis, by lot or by such other method as the Trustee in its sole discretion
shall deem to be fair and appropriate, although no Securities of $1,000 in
original principal amount or less will be redeemed in part. If any Security is
to be redeemed in part only, the notice of redemption relating to such Security
shall state the portion of the principal amount thereof to be redeemed. A new
Security in principal amount equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original
Security. On and after the redemption date, interest will cease to accrue on
Securities or portions thereof called for redemption as long as the Company has
deposited with the Paying Agent funds in satisfaction of the applicable
redemption price pursuant to the Indenture.

               In addition, the Company is entitled to redeem the Securities, at
its option, at any time as a whole but not in part, upon not less than 30 nor
more than 60 days' notice, at 100% of the principal amount thereof, plus accrued
and unpaid interest (if any) to the date of redemption (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date), in the event the Company has become or would
become obligated to pay, on the next date on which any amount would be payable
with respect to the Securities, any Additional Amounts as a result of (1) a
change in or an amendment to the laws (including any regulations or ruling
promulgated thereunder) of the Cayman Islands (or any political subdivision or
taxing authority thereof or therein) which change or amendment is announced or
becomes effective on or after September 27, 2000; or (2) any change in or
amendment to any official position regarding the application or interpretation
of such laws, regulations or rulings, or any execution of or amendment to, any
treaty or treaties affecting taxation to which such jurisdiction (or such
political subdivision or taxing authority) is a party, which change or amendment
is announced or becomes effective on or after September 27, 2000, and the
Company cannot avoid such obligation by taking reasonable measures available to
it.

<PAGE>   111

               Before the Company publishes or mails notice of redemption of the
Securities as described in the preceding paragraph, the Company shall deliver to
the Trustee an Officers' Certificate to the effect that the Company cannot avoid
its obligation to pay Additional Amounts by taking reasonable measures available
to it. The Company shall also deliver an Opinion of Counsel stating that the
Company would be obligated to pay Additional Amounts as a result of a change in
tax laws or regulations or the application or interpretation of such laws or
regulations.

6.      Repurchase Provisions

               (a) Upon a Change of Control any Holder of Securities will have
the right to cause the Company to repurchase all or any part of the Securities
of such Holder at a purchase price in cash equal to 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date) as provided in, and
subject to the terms of, the Indenture.

               (b) In the event of an Asset Disposition that requires the
purchase of Securities pursuant to Section 3.6(b) of the Indenture, the Company
will be required to apply such Excess Proceeds to the repayment of the
Securities and any Pari Passu Securities in accordance with the procedures set
forth in Section 3.6 of the Indenture.

7.      Denominations; Transfer; Exchange

               The Securities are in registered form without coupons in
denominations of principal amount of $1,000 and whole multiples of $1,000. A
Holder may transfer or exchange Securities in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of
or exchange (i) any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
for a period beginning 15 days before the mailing of a notice of Securities to
be redeemed and ending on the date of such mailing or (ii) any Securities for a
period beginning 15 days before an interest payment date and ending on such
interest payment date.

8.      Persons Deemed Owners

               The registered Holder of this Security may be treated as the
owner of it for all purposes.

9.      Unclaimed Money

               If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.



                                      A-5
<PAGE>   112

10.    Defeasance

               Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of its obligations under the
Securities and the Indenture if the Company deposits with the Trustee money or
U.S. Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

11.    Amendment, Waiver

               Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the then outstanding
Securities and (ii) any default (other than with respect to nonpayment or in
respect of a provision that cannot be amended without the written consent of
each Holder affected) or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in principal amount of the then
outstanding Securities. Subject to certain exceptions set forth in the
Indenture, without the consent of any Holder, the Company and the Trustee may
amend the Indenture or the Securities to cure any ambiguity, omission, defect or
inconsistency, or to comply with Article IV of the Indenture, or to provide for
uncertificated Securities in addition to or in place of certificated Securities,
or to add guarantees with respect to the Securities or to secure the Securities,
or to add additional covenants of the Company, or surrender rights and powers
conferred on the Company, or to comply with any request of the SEC in connection
with qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Holder, or to provide for the issuance of
Exchange Securities.

12.    Defaults and Remedies

               Under the Indenture, Events of Default include (i) default for 30
days in payment of interest when due on the Securities; (ii) default in payment
of principal or premium, if any, on the Securities at Stated Maturity, upon
required repurchase or upon optional redemption pursuant to paragraphs 5 and 6
of the Securities, upon declaration or otherwise; (iii) the failure by the
Company to comply with its obligations under Article IV of the Indenture; (iv)
failure by the Company to comply for 30 days after notice with any of its
obligations under the covenants described under Sections 3.2 through 3.17
inclusive of the Indenture (in each case, other than a failure to purchase
Securities when required pursuant to Section 3.6 or 3.8, which failure shall
constitute an Event of Default under clause (ii) above and other than a failure
to comply with Article IV or which failure shall constitute an Event of Default
under clause (iii) above); (v) the failure by the Company to comply for 60 days
after notice with its other agreements contained in the Indenture or under the
Securities (other than those referred to in (i), (ii), (iii) or (iv) above);
(vi) default under any mortgage, indenture or instrument under which there may
be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Company or any of its Restricted Subsidiaries (or the
payment of which is guaranteed by the Company or any of its Restricted
Subsidiaries), other than Indebtedness owed to the Company or a Restricted
Subsidiary, whether such Indebtedness or guarantee now exists, or is created
after the date of the Indenture, which default (a) is caused by a failure to pay
principal of, or interest or premium, if any, on such Indebtedness before the
expiration of the grace period provided in such



                                      A-6
<PAGE>   113

Indebtedness ("Payment Default") or (b) results in the acceleration of such
Indebtedness prior to its maturity (the "cross acceleration provision") and, in
each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$15.0 million or more; (vii) certain events of bankruptcy, insolvency or
reorganization of the Company or a Significant Subsidiary or group of Restricted
Subsidiaries that, taken together (as of the latest audited consolidated
financial statements for the Company and its Restricted Subsidiaries), would
constitute a Significant Subsidiary (the "bankruptcy provisions"); or (viii)
failure by the Company or any Significant Subsidiary or group of Restricted
Subsidiaries that, taken together (as of the latest audited consolidated
financial statements for the Company and its Restricted Subsidiaries) would
constitute a Significant Subsidiary to pay final judgments aggregating in excess
of $15.0 million or its foreign currency equivalent at the time (net of any
amounts with respect to which a reputable and creditworthy insurance company has
acknowledged liability in writing), which judgments are not paid, discharged or
stayed for a period of 60 days (the "judgment default provision"). However, a
default under clauses (iv) and (v) will not constitute an Event of Default until
the Trustee or the Holders of at least 25% in principal amount of the
outstanding Securities notify the Company of the default and the Company does
not cure such default within the time specified in clauses (iv) and (v) hereof
after receipt of such notice.

               If an Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the Securities may declare
all the Securities to be due and payable immediately. Certain events of
bankruptcy or insolvency are Events of Default which will result in the
Securities being due and payable immediately upon the occurrence of such Events
of Default.

               Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders notice of any continuing Default or Event of Default
(except a Default or Event of Default in payment of principal or interest) if it
determines that withholding notice is in their interest.

13.    Trustee Dealings with the Company

               Subject to certain limitations set forth in the Indenture, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.

14.    No Recourse Against Others

               An incorporator, director, officer, employee, shareholder or
controlling person, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities, the Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. By



                                      A-7
<PAGE>   114

accepting a Security, each Holder waives and releases all such liability. The
waiver and release are part of the consideration for the issue of the
Securities.

15.    Authentication

               This Security shall not be valid until an authorized signatory of
the Trustee (or an authenticating agent acting on its behalf) manually signs the
certificate of authentication on the other side of this Security.

16.    Abbreviations

               Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants
in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

17.    CUSIP Numbers

               Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures the Company has caused CUSIP numbers
to be printed on the Securities and has directed the Trustee to use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Securities
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

18.    Governing Law

               (a) This Security shall be governed by, and construed in
accordance with, the laws of the State of New York.

               (b) The Company hereby irrevocably submits to the non-exclusive
jurisdiction of any New York State or United States federal court sitting in the
Borough of Manhattan, New York City, New York, U.S.A., and any appellate court
from any thereof for the purpose of any legal action or proceeding in any such
court with respect to, or arising out of, this Agreement. The Company waives any
objection to proceedings in such courts whether on the grounds of venue,
residence or domicile or on the ground that the proceedings have been brought in
an inconvenient forum. The company agrees that a final non-appealable judgment
in any such proceeding shall be conclusive and binding upon it and may be
enforced in any court referred to above or in any other courts to the
jurisdiction of which the Company is or may be subject, by a suit upon such
judgment.

               (c) The Company designates and appoints Triton Energy
Corporation, 6688 North Central Expressway, Suite 1400, Dallas, Texas
75206-9926, Attention: General Counsel, and its successors and assigns as the
Company's lawful agent in the United States upon which may be served, and which
may accept and acknowledge, for and on behalf of the Company all process in any
action,



                                      A-8
<PAGE>   115

suit or proceedings that may be brought against the Company in any of the courts
referred to in this Section, and agrees that such service of process, or the
acceptance or acknowledgment thereof by said agent, shall be valid, effective
and binding in every respect; provided, however, that if said agency shall cease
for any reason whatsoever, the Company hereby designates and appoints, without
power of revocation, the Secretary of State of the State of New York to serve as
its agent for service of process.

               The Company will furnish to any Holder upon written request and
without charge to the Holder a copy of the Indenture which has in it the text of
this Security in larger type. Requests may be made to Triton Energy Corporation
at the above-mentioned address.

                   [FORM OF REVERSE SIDE OF EXCHANGE SECURITY]

                          8 7/8% Senior Notes due 2007

1.      Interest

               Triton Energy Limited, a Cayman Islands company (such company,
and its successors and assigns under the Indenture hereinafter referred to,
being herein called the "Company"), promises to pay interest on the principal
amount of this Security at the rate per annum shown above.

               The Company will pay interest semiannually on April 1 and October
1 of each year commencing April 1, 2001. Interest on the Securities will accrue
from the most recent date to which interest has been paid on the Securities or,
if no interest has been paid, from October 4, 2000. The Company shall pay
interest on overdue principal or premium, if any (plus interest on such interest
to the extent lawful), at the rate borne by the Securities to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

2.      Method of Payment

               By at least 10:00 a.m. (New York City time) on the date on which
any principal of or interest on any Security is due and payable, the Company
shall irrevocably deposit with the Trustee or the Paying Agent money sufficient
to pay such principal, premium, if any, and/or interest. The Company will pay
interest (except Defaulted Interest) to the Persons who are registered Holders
of Securities at the close of business on the March 15 and September 15
immediately preceding the interest payment date even if Securities are
cancelled, repurchased or redeemed after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. Payments in respect of Securities represented by a
Global Security (including principal, premium, if any, and interest) will be
made by the transfer of immediately available funds to the accounts specified by
The Depository Trust Company. The Company will make all payments in respect of a
Definitive Security (including principal, premium, if any, and interest) by
mailing a check to the registered address of each Holder thereof; provided,
however, that payments on the Securities may also be made, in the case of a
Holder of a least $1,000,000 aggregate principal amount of Securities, by wire
transfer to a U.S. dollar account maintained by the payee with a bank in the
United States if such Holder elects payment by wire transfer by giving written
notice to the Trustee or the Paying Agent to such effect designating such
account no later than 15 days immediately preceding the relevant due date for
payment (or such other date as the Trustee may accept in its discretion).

3.      Paying Agent and Registrar

               Initially, The Chase Manhattan Bank (the "Trustee"), will act as
Trustee, Paying Agent and Registrar. The Company may appoint and change any
Paying Agent, Registrar or co-registrar



                                      B-2
<PAGE>   123

without notice to any Holder. The Company or any of its Restricted Subsidiaries
may act as Paying Agent, Registrar or co-registrar.

4.      Indenture

               The Company issued the Securities under an Indenture dated as of
October 4, 2000 (as it may be amended or supplemented from time to time in
accordance with the terms thereof, the "Indenture"), among the Company and the
Trustee. The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S.C. Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the
"Act"). Capitalized terms used herein and not defined herein have the meanings
ascribed thereto in the Indenture. The Securities are subject to all such terms,
and Holders are referred to the Indenture and the Act for a statement of those
terms.

               The Securities are general unsecured senior subordinated
obligations of the Company limited to $500.0 million aggregate principal amount
(subject to Section 2.9 of the Indenture) which may be issued from time to time
under the Indenture. The Initial Securities, Private Exchange Securities and the
Exchange Securities will be treated as a single class of securities under the
Indenture. The Indenture imposes certain limitations on, among other things: the
Incurrence of Indebtedness by the Company and its Restricted Subsidiaries, the
purchase or redemption of Capital Stock of the Company, certain purchases or
redemptions of Subordinated Obligations, the Incurrence of Liens by the Company
or its Restricted Subsidiaries, the sale or transfer of assets and Capital Stock
of Restricted Subsidiaries, the issuance or sale of Capital Stock of Restricted
Subsidiaries, the business activities and investments of the Company and its
Restricted Subsidiaries, mergers and consolidation, and transactions with
Affiliates. In addition, the Indenture limits the ability of the Company and its
Restricted Subsidiaries to restrict distributions and dividends from Restricted
Subsidiaries.

5.      Redemption

               Except as set forth below, the Securities will not be redeemable
until October 1, 2004. On and after such date, the Securities will be
redeemable, at the Company's option, in whole or in part, at any time upon not
less than 30 nor more than 60 days prior notice mailed by first-class mail to
each Holder's registered address, at the following redemption prices (expressed
in percentages of principal amount), plus accrued and unpaid interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date), if
redeemed during the 12-month period commencing on October 1 of the years set
forth below:

 2006 and thereafter                                                    100.000%
</TABLE>



                                      B-3
<PAGE>   124

               In addition, at any time and from time to time prior to October
1, 2003, the Company may redeem in the aggregate up to 35% of the original
principal amount of the Securities with the Net Cash Proceeds of one or more
Equity Offerings received by the Company at a redemption price (expressed as a
percentage of principal amount) of 108.875% plus accrued and unpaid interest, if
any, to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date); provided, however, that (1) at least 65% of the original principal amount
of the Securities must remain outstanding after each such redemption; and (2)
that each such redemption occurs within 120 days of the date of closing of such
Equity Offering. Pending the application of the Net Cash Proceeds of any Equity
Offering to redeem Securities in accordance with the provisions of this
paragraph, the Company or its Restricted Subsidiaries may temporarily repay
Senior Indebtedness until those Net Cash Proceeds.

               In the case of any partial redemption, selection of the
Securities for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities are listed or, if the Securities are not listed, then on a pro rata
basis, by lot or by such other method as the Trustee in its sole discretion
shall deem to be fair and appropriate, although no Securities of $1,000 in
original principal amount or less will be redeemed in part. If any Security is
to be redeemed in part only, the notice of redemption relating to such Security
shall state the portion of the principal amount thereof to be redeemed. A new
Security in principal amount equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original
Security. On and after the redemption date, interest will cease to accrue on
Securities or portions thereof called for redemption as long as the Company has
deposited with the Paying Agent funds in satisfaction of the applicable
redemption price pursuant to the Indenture.

               In addition, the Company is entitled to redeem the Securities, at
its option, at any time as a whole but not in part, upon not less than 30 nor
more than 60 days' notice, at 100% of the principal amount thereof, plus accrued
and unpaid interest (if any) to the date of redemption (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date), in the event the Company has become or would
become obligated to pay, on the next date on which any amount would be payable
with respect to the Securities, any Additional Amounts as a result of (1) a
change in or an amendment to the laws (including any regulations or ruling
promulgated thereunder) of the Cayman Islands (or any political subdivision or
taxing authority thereof or therein) which change or amendment is announced or
becomes effective on or after September 27, 2000; or (2) any change in or
amendment to any official position regarding the application or interpretation
of such laws, regulations or rulings, or any execution of or amendment to, any
treaty or treaties affecting taxation to which such jurisdiction (or such
political subdivision or taxing authority) is a party, which change or amendment
is announced or becomes effective on or after September 27, 2000, and the
Company cannot avoid such obligation by taking reasonable measures available to
it.

               Before the Company publishes or mails notice of redemption of the
Securities as described in the preceding paragraph, the Company shall deliver to
the Trustee an Officers' Certificate to the effect that the Company cannot avoid
its obligation to pay Additional Amounts by taking reasonable measures available
to it. The Company shall also deliver an Opinion of Counsel stating that



                                      B-4
<PAGE>   125

the Company would be obligated to pay Additional Amounts as a result of a change
in tax laws or regulations or the application or interpretation of such laws or
regulations.

6.      Repurchase Provisions

               (a) Upon a Change of Control any Holder of Securities will have
the right to cause the Company to repurchase all or any part of the Securities
of such Holder at a purchase price in cash equal to 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date) as provided in, and
subject to the terms of, the Indenture.

               (b) In the event of an Asset Disposition that requires the
purchase of Securities pursuant to Section 3.6(b) of the Indenture, the Company
will be required to apply such Excess Proceeds to the repayment of the
Securities and any Pari Passu Securities in accordance with the procedures set
forth in Section 3.6 of the Indenture.

7.      Denominations; Transfer; Exchange

               The Securities are in registered form without coupons in
denominations of principal amount of $1,000 and whole multiples of $1,000. A
Holder may transfer or exchange Securities in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of
or exchange (i) any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
for a period beginning 15 days before the mailing of a notice of Securities to
be redeemed and ending on the date of such mailing or (ii) any Securities for a
period beginning 15 days before an interest payment date and ending on such
interest payment date.

8.      Persons Deemed Owners

               The registered Holder of this Security may be treated as the
owner of it for all purposes.

9.      Unclaimed Money

               If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.



                                      B-5
<PAGE>   126

10.    Defeasance

               Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of its obligations under the
Securities and the Indenture if the Company deposits with the Trustee money or
U.S. Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

11.    Amendment, Waiver

               Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the then outstanding
Securities and (ii) any default (other than with respect to nonpayment or in
respect of a provision that cannot be amended without the written consent of
each Holder affected) or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in principal amount of the then
outstanding Securities. Subject to certain exceptions set forth in the
Indenture, without the consent of any Holder, the Company and the Trustee may
amend the Indenture or the Securities to cure any ambiguity, omission, defect or
inconsistency, or to comply with Article IV of the Indenture, or to provide for
uncertificated Securities in addition to or in place of certificated Securities,
or to add guarantees with respect to the Securities or to secure the Securities,
or to add additional covenants of the Company, or surrender rights and powers
conferred on the Company, or to comply with any request of the SEC in connection
with qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Holder, or to provide for the issuance of
Exchange Securities.

12.    Defaults and Remedies

               Under the Indenture, Events of Default include (i) default for 30
days in payment of interest when due on the Securities; (ii) default in payment
of principal or premium, if any, on the Securities at Stated Maturity, upon
required repurchase or upon optional redemption pursuant to paragraphs 5 and 6
of the Securities, upon declaration or otherwise; (iii) the failure by the
Company to comply with its obligations under Article IV or Section 11.2 of the
Indenture; (iv) failure by the Company to comply for 30 days after notice with
any of its obligations under the covenants described under Sections 3.2 through
3.17 inclusive of the Indenture (in each case, other than a failure to purchase
Securities when required pursuant to Section 3.6 or 3.8, which failure shall
constitute an Event of Default under clause (ii) above and other than a failure
to comply with Article IV which failure shall constitute an Event of Default
under clause (iii) above); (v) the failure by the Company to comply for 60 days
after notice with its other agreements contained in the Indenture or under the
Securities (other than those referred to in (i), (ii), (iii) or (iv) above);
(vi) default under any mortgage, indenture or instrument under which there may
be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Company or any of its Restricted Subsidiaries (or the
payment of which is guaranteed by the Company or any of its Restricted
Subsidiaries), other than Indebtedness owed to the Company or a Restricted
Subsidiary, whether such Indebtedness or guarantee now exists, or is created
after the date of the Indenture, which default (a) is caused by a failure to pay
principal of, or interest or premium, if any, on such Indebtedness before the
expiration of



                                      B-6
<PAGE>   127

the grace period provided in such Indebtedness ("Payment Default") or (b)
results in the acceleration of such Indebtedness prior to its maturity (the
"cross acceleration provision") and, in each case, the principal amount of any
such Indebtedness, together with the principal amount of any other such
Indebtedness under which there has been a Payment Default or the maturity of
which has been so accelerated, aggregates $15.0 million or more; (vii) certain
events of bankruptcy, insolvency or reorganization of the Company or a
Significant Subsidiary or group of Restricted Subsidiaries that, taken together
(as of the latest audited consolidated financial statements for the Company and
its Restricted Subsidiaries), would constitute a Significant Subsidiary (the
"bankruptcy provisions"); or (viii) failure by the Company or any Significant
Subsidiary or group of Restricted Subsidiaries that, taken together (as of the
latest audited consolidated financial statements for the Company and its
Restricted Subsidiaries) would constitute a Significant Subsidiary to pay final
judgments aggregating in excess of $15.0 million or its foreign currency
equivalent at the time (net of any amounts with respect to which a reputable and
creditworthy insurance company has acknowledged liability in writing), which
judgments are not paid, discharged or stayed for a period of 60 days (the
"judgment default provision"). However, a default under clauses (iv) and (v)
will not constitute an Event of Default until the Trustee or the Holders of at
least 25% in principal amount of the outstanding Securities notify the Company
of the default and the Company does not cure such default within the time
specified in clauses (iv) and (v) hereof after receipt of such notice.

               If an Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the Securities may declare
all the Securities to be due and payable immediately. Certain events of
bankruptcy or insolvency are Events of Default which will result in the
Securities being due and payable immediately upon the occurrence of such Events
of Default.

               Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders notice of any continuing Default or Event of Default
(except a Default or Event of Default in payment of principal or interest) if it
determines that withholding notice is in their interest.

13.    Trustee Dealings with the Company

               Subject to certain limitations set forth in the Indenture, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.

14.    No Recourse Against Others

               An incorporator, director, officer, employee, shareholder or
controlling person, as such, of the Company, shall not have any liability for
any obligations of the Company under the Securities, the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. By



                                      B-7
<PAGE>   128

accepting a Security, each Holder waives and releases all such liability. The
waiver and release are part of the consideration for the issue of the
Securities.

15.    Authentication

               This Security shall not be valid until an authorized signatory of
the Trustee (or an authenticating agent acting on its behalf) manually signs the
certificate of authentication on the other side of this Security.

16.    Abbreviations

               Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants
in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

17.    CUSIP Numbers

               Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures the Company has caused CUSIP numbers
to be printed on the Securities and has directed the Trustee to use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Securities
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

18.    Governing Law

               (a) This Security shall be governed by, and construed in
accordance with, the laws of the State of New York.

               (b) The Company hereby irrevocably submits to the non-exclusive
jurisdiction of any New York State or United States federal court sitting in the
Borough of Manhattan, New York City, New York, U.S.A., and any appellate court
from any thereof for the purpose of any legal action or proceeding in any such
court with respect to, or arising out of, this Agreement. The Company waives any
objection to proceedings in such courts whether on the grounds of venue,
residence or domicile or on the ground that the proceedings have been brought in
an inconvenient forum. The company agrees that a final non-appealable judgment
in any such proceeding shall be conclusive and binding upon it and may be
enforced in any court referred to above or in any other courts to the
jurisdiction of which the Company is or may be subject, by a suit upon such
judgment.

               (c) The Company designates and appoints Triton Energy
Corporation, 6688 North Central Expressway, Suite 1400, Dallas, Texas
75206-9926, Attention: General Counsel, and its successors and assigns as the
Company's lawful agent in the United States upon which may be served, and which
may accept and acknowledge, for and on behalf of the Company all process in any
action,



                                      B-8
<PAGE>   129

suit or proceedings that may be brought against the Company in any of the courts
referred to in this Section, and agrees that such service of process, or the
acceptance or acknowledgment thereof by said agent, shall be valid, effective
and binding in every respect; provided, however, that if said agency shall cease
for any reason whatsoever, the Company hereby designates and appoints, without
power of revocation, the Secretary of State of the State of New York to serve as
its agent for service of process.

               The Company will furnish to any Holder upon written request and
without charge to the Holder a copy of the Indenture which has in it the text of
this Security in larger type. Requests may be made to Triton Energy Corporation
at the above mentioned address.
