                                       12
<Page>

          (n)  whether the Securities of the series shall be issued in whole or
               in part in the form of a Global Security or Securities; the terms
               and conditions, if any, upon which such Global Security or
               Securities may be exchanged in whole or in part for other
               individual Securities, and the Depositary for such Global
               Security and Securities;

          (o)  any addition to or change in the provisions set forth in Article
               10 that applies to Securities of that series;

          (p)  any addition to or change in the provisions set forth in Article
               11 that applies to Securities of that series;

          (q)  any other terms of the series (which terms shall not be
               inconsistent with the provisions of this Indenture, but which may
               modify or delete any provision of this Indenture with respect to
               such series; PROVIDED, HOWEVER, that no such term may modify or
               delete any provision hereof if imposed by the TIA; AND PROVIDED,
               FURTHER, that any modification or deletion of the rights, duties
               or immunities of the Trustee hereunder shall have been consented
               to in writing by the Trustee).

               All Securities of any series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to such Board Resolution or Officers' Certificate or in any such indenture
supplemental hereto.

               The Company may issue additional Securities of a particular
series after Securities of that series have been issued ("ADDITIONAL
SECURITIES"). The Securities of a particular series together with any Additional
Securities of that series would be treated as a single series for all purposes
under the Indenture, including without limitation, waivers, amendments,
redemptions and offers to the purchase.

               The Principal of and any interest on the Securities of a series
shall be payable at the office or agency of the Company designated in the form
of Security for the series (each such place herein called the "PLACE OF
PAYMENT"); PROVIDED, however, that payment of interest may be made at the option
of the Company by check mailed to the address of the Person entitled thereto as
such address shall appear in the register of Securities referred to in Section
2.03.

               GLOBAL AND DEFINITIVE SECURITIES. Securities of a series may be
issued as Global Securities or as Definitive Securities and shall be in such
form from time to time established by or pursuant to a Board Resolution or
Officers' Certificate, or established by one or more indentures supplemental
hereto. Each Global Security shall represent such of the outstanding Securities
of a series as shall be specified therein and each shall provide that it shall
represent the aggregate principal amount of such outstanding Securities of that
series from time to time endorsed thereon and that the aggregate principal
amount of outstanding Securities represented thereby may from time to time be
reduced or increased, as appropriate, to reflect exchanges and redemptions. Any
endorsement of a Global Security to reflect the amount of any increase or
decrease in the aggregate principal amount of outstanding Securities represented
thereby shall be made by the Trustee or the Custodian, at the direction of the
Trustee, in accordance with instructions given by the Holder thereof as required
by Section 2.06.

               TEMPORARY GLOBAL SECURITIES. Securities of a series offered and
sold in reliance on Regulation S shall be issued initially in the form of the
Regulation S Temporary Global Security, which shall be deposited on behalf of
the purchasers of the Securities represented thereby with the Trustee, at its
Corporate Trust Office, as custodian for the Depositary, and registered in the
name of the Depositary or the nominee of the Depositary for the accounts of
designated agents holding on behalf of Euroclear or Clearstream, duly executed
by the Company and authenticated by the Trustee as hereinafter provided. The
Restricted Period shall terminate upon the receipt by the Trustee of (i) a
written certificate from the Depositary, together with copies of certificates
from Euroclear and Clearstream certifying that they have received certification
of non-United States beneficial ownership of 100% of the aggregate principal
amount of the Regulation S Temporary Global Security (except to the extent of
any beneficial owners thereof who acquired an interest therein during the
Restricted Period pursuant to another exemption from registration under the
Securities Act and who will take delivery of a beneficial ownership interest in
a 144A Global Security bearing a Private Placement Legend, all as contemplated
by Section 2.06(a)(ii)), and (ii) an Officers' Certificate from the Company.
Following the termination of the Restricted Period, beneficial interests in the
Regulation S Temporary Global Security shall be exchanged for beneficial
interests in Regulation S Permanent Global Securities pursuant to the Applicable
Procedures. Simultaneously with the authentication of Regulation S Permanent
Global Securities, the Trustee shall cancel the Regulation S Temporary Global
Security. The aggregate principal amount of the Regulation S Temporary Global
Security and the Regulation S Permanent Global Securities may from time to time
be increased or decreased by adjustments made on the records of the Trustee and
the Depositary or its nominee, as the case may be, in connection with transfers
of interest as hereinafter provided.

               EUROCLEAR AND CLEARSTREAM PROCEDURES APPLICABLE. The provisions
of the "Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of
Clearstream" and "Customer Handbook" of Clearstream shall be applicable to
transfers of beneficial interests in the Regulation S Temporary Global Security
and the Regulation S Permanent Global Securities that are held by Participants
through Euroclear or Clearstream.

               Prior to the delivery of a Security to the Trustee for
authentication in any form approved by or pursuant to a Board Resolution or
Officers' Certificate, the Company shall deliver to the Trustee the Board
Resolution or Officers' Certificate by or pursuant to which such form of
Security has been approved, which Board Resolution or Officers' Certificate
shall have attached thereto a true and correct copy of the form of Security that
has been approved by or pursuant thereto.

               The Securities may have notations, legends or endorsements
required by law, stock exchange rule or usage. Each Security shall be dated the
date of its authentication.

SECTION 2.02.  EXECUTION AND AUTHENTICATION.

               Two Officers shall sign the Securities for the Company by manual
or facsimile signature.

                                       14
<Page>

               If an Officer whose signature is on a Security no longer holds
that office at the time the Security is authenticated, the Security shall
nevertheless be valid.

               A Security shall not be valid until authenticated by the manual
signature of the Trustee. The signature shall be conclusive evidence that the
Security has been authenticated under this Indenture.

               The Trustee shall authenticate Securities for original issue upon
a Company Order.

               The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Securities. An authenticating agent may authenticate
Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company.

SECTION 2.03.  REGISTRAR AND PAYING AGENT.

               The Company shall maintain an office or agency where Securities
of a particular series may be presented for registration of transfer or for
exchange (the "REGISTRAR") and an office or agency where Securities of that
series may be presented for payment (a "PAYING AGENT"). The Registrar for a
particular series of Securities shall keep a register of the Securities of that
series and of their transfer and exchange. The Company may appoint one or more
co-Registrars and one or more additional paying agents for each series of
Securities. The term "PAYING AGENT" includes any additional paying agent. The
Company may change any Paying Agent, Registrar or co-Registrar without prior
notice to any Holder. The Company shall notify the Trustee in writing of the
name and address of any Agent not a party to this Indenture.

               If the Company fails to maintain a Registrar or Paying Agent for
any series of Securities, the Trustee shall act as such. The Company or any of
its Affiliates may act as Paying Agent, Registrar or co-Registrar.

               The Company hereby appoints the Trustee as the initial Registrar
and Paying Agent for each series of Securities unless another Registrar or
Paying Agent, as the case may be, is appointed prior to the time Securities of
that series are first issued.

SECTION 2.04.  PAYING AGENT TO HOLD MONEY IN TRUST.

               Whenever the Company has one or more Paying Agents it shall,
prior to each due date of the Principal of or interest on, any Securities,
deposit with a Paying Agent a sum sufficient to pay the Principal or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such Principal or interest, and (unless such Paying Agent is the
Trustee) the Company shall promptly notify the Trustee of its action or failure
so to act.

               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 the Holders of the particular series for which it is acting, or the
Trustee, all money held by the Paying Agent for the payment of Principal or
interest on the Securities of such series, and that such Paying Agent shall
notify

                                       15
<Page>

the Trustee of any Default by the Company or any other obligor of the series of
Securities in making any such payment and at any time during the continuance of
any such Default, upon the written request of the Trustee, forthwith pay to the
Trustee all sums so held in trust by such Paying Agent. If the Company or an
Affiliate acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders of the particular series for which it is
acting all money held by it as Paying Agent. The Company at any time may require
a Paying Agent to pay all money held by it to the Trustee. Upon so doing, the
Paying Agent (if other than the Company or an Affiliate of the Company) shall
have no further liability for such money. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Paying Agent for
the Securities.

SECTION 2.05.  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, separately by series, and shall otherwise comply with TIA Section
312(a). If the Trustee is not the Registrar, the Company shall furnish to the
Trustee 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, separately by series, relating to such interest payment date or
request, as the case may be.

SECTION 2.06.  TRANSFER AND EXCHANGE.

        (a)    TRANSFER AND EXCHANGE OF GLOBAL SECURITIES. A Global Security may
               not be transferred as a whole except by the Depositary to a
               nominee of the Depositary, by a nominee of the Depositary to the
               Depositary or to another nominee of the Depositary, or by the
               Depositary or any such nominee to a successor Depositary or a
               nominee of such successor Depositary. Global Securities of any
               series will not be exchanged by the Company for Definitive
               Securities unless (i) the Company delivers to the Trustee notice
               from the Depositary that it is unwilling or unable to continue to
               act as Depositary or that it is no longer a clearing agency
               registered under the Exchange Act and, in either case, a
               successor Depositary is not appointed by the Company within 120
               days after the date of such notice from the Depositary; (ii) the
               Company in its sole discretion determines that the Global
               Securities of such series (in whole but not in part) should be
               exchanged for Definitive Securities and delivers a written notice
               to such effect to the Trustee (PROVIDED that in no event shall
               the Regulation S Temporary Global Security be exchanged by the
               Company for Definitive Securities prior to (x) the expiration of
               the Restricted Period and (y) the receipt by the Registrar of any
               certificates required pursuant to Rule 903(b)(3)(ii)(B) under the
               Securities Act; or (iii) an Event of Default shall have occurred
               and be continuing with respect to the Securities and the Trustee
               has received a request from DTC or any Holder to issue Definitive
               Securities. Upon the occurrence of any of the preceding events in
               (i), (ii) or (iii) above, Definitive Securities shall be issued
               in such names as the Depositary shall instruct the Trustee.
               Global Securities also may be exchanged or replaced, in whole or
               in part, as PROVIDED in Sections 2.07 and 2.09. Every Security
               authenticated and delivered in exchange for, or in lieu of, a
               Global

                                       16
<Page>

               Security or any portion thereof, pursuant to this Section 2.06 or
               Section 2.07 or 2.09, shall be authenticated and delivered in the
               form of, and shall be, a Global Security. A Global Security may
               not be exchanged for another Security other than as PROVIDED in
               this Section 2.06(a), however, beneficial interests in a Global
               Security may be transferred and exchanged as provided in Section
               2.06(b), (c) or (f).

        (b)    TRANSFER AND EXCHANGE OF BENEFICIAL INTERESTS IN GLOBAL
               SECURITIES. The transfer and exchange of beneficial interests in
               the Global Securities shall be effected through the Depositary,
               in accordance with the provisions of this Indenture and the
               Applicable Procedures. Beneficial interests in the Restricted
               Global Securities shall be subject to restrictions on transfer
               comparable to those set forth herein to the extent required by
               the Securities Act. Transfers of beneficial interests in the
               Global Securities also shall require compliance with either
               subparagraph (i) or (ii) below, as applicable, as well as one or
               more of the other following subparagraphs, as applicable:

                    (i)    TRANSFER OF BENEFICIAL INTERESTS IN THE SAME GLOBAL
               SECURITY. Beneficial interests in any Restricted Global Security
               may be transferred to Persons who take delivery thereof in the
               form of a beneficial interest in the same Restricted Global
               Security in accordance with the transfer restrictions set forth
               in the Private Placement Legend; PROVIDED, however, that prior to
               the expiration of the Restricted Period, transfers of beneficial
               interests in the Temporary Regulation S Global Security may not
               be made to a U.S. Person or for the account or benefit of a U.S.
               Person (other than an initial purchaser). Beneficial interests in
               any Unrestricted Global Security may be transferred to Persons
               who take delivery thereof in the form of a beneficial interest in
               an Unrestricted Global Security. No written orders or
               instructions shall be required to be delivered to the Registrar
               to effect the transfers described in this Section 2.06(b)(i).

                    (ii)   ALL OTHER TRANSFERS AND EXCHANGES OF BENEFICIAL
               INTERESTS IN GLOBAL SECURITIES. In connection with all transfers
               and exchanges of beneficial interests in any Global Security that
               is not subject to Section 2.06(b)(i) above, the transferor of
               such beneficial interest must deliver to the Registrar (1) a
               written order from a Participant or an Indirect Participant given
               to the Depositary in accordance with the Applicable Procedures
               directing the Depositary to credit or cause to be credited a
               beneficial interest in another Global Security in an amount equal
               to the beneficial interest to be transferred or exchanged and (2)
               instructions given in accordance with the Applicable Procedures
               containing information regarding the Participant account to be
               credited with such increase. Upon consummation of an Exchange
               Offer for a series of Global Securities in accordance with
               Section 2.06(f), the requirements of this Section 2.06(b)(ii)
               shall be deemed to have been satisfied upon receipt by the
               Registrar of the instructions contained in the Letter of
               Transmittal delivered by the holder of such beneficial interests
               in the Restricted Global Securities. Upon satisfaction of all of
               the requirements for transfer or exchange of beneficial interests
               in Global Securities contained in this Indenture and the
               Securities of a series or otherwise applicable

                                       17
<Page>

               under the Securities Act, the Trustee shall adjust the Principal
               amount of the relevant Global Security(s) pursuant to Section
               2.06(h).

                    (iii)  TRANSFER OF BENEFICIAL INTERESTS TO ANOTHER
               RESTRICTED GLOBAL SECURITY. A beneficial interest in any
               Restricted Global Security may be transferred to a Person who
               takes delivery thereof in the form of a beneficial interest in
               another Restricted Global Security if the transfer complies with
               the requirements of Section 2.06(b)(ii) above and the Registrar
               receives the following:

                         (A)  if the transferee will take delivery in the form
                    of a beneficial interest in a 144A Global Security, then the
                    transferor must deliver a certificate in the form of Exhibit
                    A hereto, including the certifications in item (1) thereof;
                    and

                         (B)  if the transferee will take delivery in the form
                    of a beneficial interest in a Regulation S Temporary Global
                    Security or a Regulation S Global Security, then the
                    transferor must deliver a certificate in the form of Exhibit
                    A hereto, including the certifications in item (2) thereof.

                    (iv)   TRANSFER AND EXCHANGE OF BENEFICIAL INTERESTS IN A
               RESTRICTED GLOBAL SECURITY FOR BENEFICIAL INTERESTS IN AN
               UNRESTRICTED GLOBAL SECURITY. A beneficial interest in any
               Restricted Global Security may be exchanged by any holder thereof
               for a beneficial interest in an Unrestricted Global Security or
               transferred to a Person who takes delivery thereof in the form of
               a beneficial interest in an Unrestricted Global Security if the
               exchange or transfer complies with the requirements of Section
               2.06(b)(ii) above and:

                         (A)  such exchange or transfer is effected pursuant to
                    the Exchange Offer in accordance with the Registration
                    Rights Agreement and the holder of the beneficial interest
                    to be transferred, in the case of an exchange, or the
                    transferee, in the case of a transfer, certifies in the
                    applicable Letter of Transmittal that it is not (1) a
                    broker-dealer, (2) a Person participating in the
                    distribution of the Exchange Securities or (3) a Person who
                    is an affiliate (as defined in Rule 144) of the Company;

                         (B)  such transfer is effected pursuant to the Shelf
                    Registration Statement in accordance with the Registration
                    Rights Agreement;

                         (C)  such transfer is effected by a Broker-Dealer
                    pursuant to the Exchange Offer Registration Statement in
                    accordance with the Registration Rights Agreement; or

                         (D)  the Registrar receives the following:

                              (1)  if the holder of such beneficial interest in
                         a Restricted Global Security proposes to exchange such
                         beneficial

                                       18
<Page>

                         interest for a beneficial interest in an Unrestricted
                         Global Security, a certificate from such holder in the
                         form of Exhibit B hereto, including the certifications
                         in item (1)(a) thereof; or

                              (2)  if the holder of such beneficial interest in
                         a Restricted Global Security proposes to transfer such
                         beneficial interest to a Person who shall take delivery
                         thereof in the form of a beneficial interest in an
                         Unrestricted Global Security, a certificate from such
                         holder in the form of Exhibit A hereto, including the
                         certifications in item (4) thereof;

               and, in each such case set forth in this subparagraph (D), if the
               Registrar so requests or if the Applicable Procedures so require,
               an Opinion of Counsel in form reasonably acceptable to the
               Registrar to the effect that such exchange or transfer is in
               compliance with the Securities Act and that the restrictions on
               transfer contained herein and in the Private Placement Legend are
               no longer required in order to maintain compliance with the
               Securities Act.

               If any such transfer is effected pursuant to subparagraph (B) or
(D) above at a time when an Unrestricted Global Security has not yet been
issued, the Company shall issue and, upon receipt of a Company Order in
accordance with Section 2.02, the Trustee shall authenticate one or more
Unrestricted Global Securities in an aggregate principal amount equal to the
aggregate principal amount of beneficial interests transferred pursuant to
subparagraph (B) or (D) above.

               Beneficial interests in an Unrestricted Global Security cannot be
exchanged for, or transferred to Persons who take delivery thereof in the form
of, a beneficial interest in a Restricted Global Security.

          (c)  TRANSFER AND EXCHANGE OF BENEFICIAL INTERESTS IN GLOBAL
               SECURITIES FOR DEFINITIVE SECURITIES. A beneficial interest in a

                         hereto, including the certifications in item (4)
                         thereof;

               and, in each such case set forth in this subparagraph (D), if the
               Registrar so requests or if the Applicable Procedures so require,

               delivery thereof in the form of a beneficial interest in an
               Unrestricted Global Security at any time. Upon receipt of a
               request for such an exchange or transfer, the Trustee shall

        APPLICABLE SIMILAR LAWS.

        (2)    Notwithstanding the foregoing, any Global Security or Definitive
               Security issued pursuant to subparagraph (b)(iv), (d)(ii),
               (d)(iii), (e)(ii), (e)(iii) or (f) of this Section 2.06 or any
               Global Security or Definitive Security initially issued by the
               Company pursuant to an effective registration statement under the
               Securities Act (and all Securities issued in exchange therefor or
               substitution thereof) shall not bear the Private Placement
               Legend.

                    (ii) GLOBAL SECURITY LEGEND. Each Global Security shall bear
               a legend in substantially the following form:

               "THIS GLOBAL SECURITY IS HELD BY THE DEPOSITARY (AS DEFINED IN
        THE INDENTURE GOVERNING THIS SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE
        BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY
        PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH
        NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO THE INDENTURE, (II) THIS
        GLOBAL SECURITY MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO
        SECTION 2.06(a)

                                       25
<Page>

        OF THE INDENTURE, (III) THIS GLOBAL SECURITY MAY BE DELIVERED TO THE
        TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.10 OF THE INDENTURE AND
        (IV) THIS GLOBAL SECURITY MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY
        WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.

               UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR
        SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED
        EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY
        A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE
        DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR
        DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS
        CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
        DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK) ("DTC")
        TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
        PAYMENT AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE &
        CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED
        REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH
        OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
        DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY
        OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF,
        CEDE & CO., HAS AN INTEREST HEREIN."

                    (iii)  REGULATION S TEMPORARY GLOBAL SECURITY LEGEND. The
               Regulation S Temporary Global Security shall bear a legend in
               substantially the following form:

               "THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL
        SECURITY, AND THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR
        CERTIFICATED SECURITIES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED
        HEREIN). NEITHER THE HOLDER NOR THE BENEFICIAL OWNERS OF THIS REGULATION
        S TEMPORARY GLOBAL SECURITY SHALL BE ENTITLED TO RECEIVE PAYMENT OF
        INTEREST HEREON."

        (h)    CANCELLATION AND/OR ADJUSTMENT OF GLOBAL SECURITIES. At such time
               as all beneficial interests in a particular Global Security have
               been exchanged for Definitive Securities or a particular Global
               Security has been redeemed, repurchased or canceled in whole and
               not in part, each such Global Security shall be returned to or
               retained and canceled by the Trustee in accordance with Section
               2.10. At any time prior to such cancellation, if any beneficial
               interest in a Global Security is exchanged for or transferred to
               a Person who will take delivery thereof in the form of a
               beneficial interest in another Global Security or for Definitive
               Securities, the principal amount of Securities represented by
               such Global Security shall be reduced accordingly and an
               endorsement shall be made on such Global Security by the Trustee
               or by the Depositary at the direction of the Trustee to

                                       26
<Page>

               reflect such reduction; and if the beneficial interest is being
               exchanged for or transferred to a Person who will take delivery
               thereof in the form of a beneficial interest in another Global
               Security, such other Global Security shall be increased
               accordingly and an endorsement shall be made on such Global
               Security by the Trustee or by the Depositary at the direction of
               the Trustee to reflect such increase.

        (i)    GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES.

                    (i)    Where Securities of a series are presented to the
               Registrar or a co-Registrar with a request to register a transfer
               or to exchange them for an equal principal amount of Securities
               of the same series of other authorized denominations, the
               Registrar shall register the transfer or make the exchange if its
               requirements for such transactions are met. To permit
               registrations of transfers and exchanges, the Company shall issue
               and the Trustee shall authenticate Global Securities and
               Definitive Securities at the Registrar's request.

                    (ii)   No service charge shall be made for any registration
               of transfer or exchange, but the Company may require payment of a
               sum sufficient to cover any transfer tax or similar governmental
               charge payable in connection therewith (other than any such
               transfer tax or similar governmental charge payable upon
               exchanges pursuant to Sections 2.09, 3.06 or 9.04).

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

                    (iv)   The Company and the Registrar shall not be required
               (A) to issue, to register the transfer of or to exchange any
               Securities during a period beginning at the opening of business
               15 days before the day of any selection of Securities of that
               series for redemption under Section 3.02 and ending at the close
               of business on the day of selection, (B) to register the transfer
               of or to exchange any Security so selected for redemption in
               whole or in part, except the unredeemed portion of any Security
               being redeemed in part or (c) to register the transfer of or to
               exchange a Security between a record date and the next succeeding
               Interest Payment Date.

                    (v)    Prior to due presentment for the registration of a
               transfer of any Security, the Trustee, any Agent and the Company
               may deem and treat the Person in whose name any Security is
               registered as the absolute owner of such Security for the purpose
               of receiving payment of Principal of and interest on such
               Securities and for all other purposes, and none of the Trustee,
               any Agent or the Company shall be affected by notice to the
               contrary.

                                       27
<Page>

                    (vi)   The Trustee shall authenticate Global Securities and
               Definitive Securities in accordance with the provisions of
               Section 2.02.

                    (vii)  All certifications, certificates and Opinions of
               Counsel required to be submitted to the Registrar pursuant to
               this Section 2.06 to effect a registration of transfer or
               exchange may be submitted by facsimile.

                    (viii) Each Holder of a Security agrees to indemnify the
               Company and the Trustee against any liability that may result
               from the transfer, exchange or assignment of such Holder's
               Security in violation of any provision of this Indenture and/or
               applicable United States federal or state securities law.

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 Depositary Participants or
beneficial owners of interests 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.

SECTION 2.07.  REPLACEMENT SECURITIES.

               If a mutilated Security is surrendered to the Trustee 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 of the same series if the Company's and the Trustee's
requirements are met. The Trustee or the Company may require an indemnity bond
to be furnished which is sufficient in the judgment of both to protect the
Company, the Trustee, and any Agent from any loss which any of them may suffer
if a Security is replaced. The Company may charge such Holder for its expenses
in replacing a Security.

               Every replacement Security is an obligation of the Company and
shall be entitled to all the benefit of this Indenture equally and
proportionately with any and all other Securities of the same series.

SECTION 2.08.  OUTSTANDING SECURITIES.

               The Securities of any series outstanding at any time are all the
Securities of that series authenticated by the Trustee, except for those
cancelled by it, those delivered to it for cancellation, and those described in
this Section 2.08 as not outstanding. Except as set forth in the final paragraph
of this Section 2.08, a Security does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Security.

               If a Security is replaced pursuant to Section 2.07, it ceases to
be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

                                       28
<Page>

               If Securities are considered paid under Section 4.01, they cease
to be outstanding and interest on them ceases to accrue.

               For each series of Original Issue Discount Securities, the
principal amount of such Securities that shall be deemed to be outstanding and
used to determine whether the necessary Holders have given any request, demand,
authorization, direction, notice, consent or waiver shall be the principal
amount of such Securities that could be declared to be due and payable upon
acceleration upon an Event of Default as of the date of such determination. When
requested by the Trustee, the Company shall advise the Trustee of such amount,
showing its computations in reasonable detail.

               In determining whether the Holders of the required principal
amount of Securities of any series have concurred in any 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 considered as though not outstanding, except
that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Securities as to which a
Trust Officer of the Trustee has actual knowledge are so owned shall be so
disregarded.

SECTION 2.09.  TEMPORARY SECURITIES.

               Until definitive Securities are ready for delivery, the Company
may prepare and the Trustee shall authenticate temporary Securities upon a
written order of the Company signed by two Officers of the Company. 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 in exchange for temporary Securities.

               Holders of temporary securities shall be entitled to all of the
benefits of this Indenture.

 SECTION 2.10.  CANCELLATION.

               The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee shall cancel all Securities surrendered for registration of
transfer, exchange, payment, replacement or cancellation and the Trustee shall
destroy cancelled securities and provide a certificate of destruction to the
Company. The Company may not issue new Securities to replace Securities that it
has paid or that have been delivered to the Trustee for cancellation.

SECTION 2.11.  DEFAULTED INTEREST.

               If the Company fails to make a payment of interest on any series
of Securities, it shall pay such defaulted interest plus (to the extent lawful)
any interest payable on the defaulted interest, in any lawful manner. It may
elect to pay such defaulted interest, plus any such interest payable on it, to
the Persons who are Holders of such Securities on which the interest is due on a
subsequent special record date, which special record date shall be fixed in the
following manner.

                                       29
<Page>

The Company shall notify the Trustee in writing of the amount of defaulted
interest proposed to be paid on each Security of such series and the date of the
proposed payment, and at the same time the Company shall deposit with the
Trustee an amount of money in the currency or currency unit in which the
Securities of such series are payable, 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. Thereupon the Company shall fix a
special record date for the payment of such defaulted interest which shall be
not more than 15 days and not less than 10 days prior to the date of the
proposed payment. The Company shall cause notice of the proposed payment of such
defaulted interest and the special record date therefor to be mailed,
first-class postage prepaid, to each Holder of Securities of such series at the
address as it appears in the register of Securities referred to in Section 2.03,
not less than 10 days prior to such special record date. Notice of the proposed
payment of such defaulted interest and the special record date therefor having
been so mailed, defaulted interest shall be paid to the Persons in whose names
the Securities of such series are registered at the close of business on such
special record date.

SECTION 2.12.  SPECIAL RECORD DATES.

        (a)    The Company may, but shall not be obligated to, set a record date
               for the purpose of determining the identity of Holders entitled
               to consent to any supplement, amendment or waiver permitted by
               this Indenture. If a record date is fixed, the Holders of
               Securities of that series outstanding on such record date, and no
               other Holders, shall be entitled to consent to such supplement,
               amendment or waiver or revoke any consent previously given,
               whether or not such Holders remain Holders after such record
               date. No consent shall be valid or effective for more than 90
               days after such record date unless consents from Holders of the
               principal amount of Securities of that series required hereunder
               for such amendment or waiver to be effective shall have also been
               given and not revoked within such 90-day period.

        (b)    The Company may, but shall not be obligated to, fix any day as a
               record date for the purpose of determining the Holders of any
               series of Securities entitled to join in the giving or making of
               any notice of Default, any declaration of acceleration, any
               request to institute proceedings or any other similar direction.
               If a record date is fixed, the Holders of Securities of that
               series outstanding on such record date, and no other Holders,
               shall be entitled to join in such notice, declaration, request or
               direction, whether or not such Holders remain Holders after such
               record date; PROVIDED, HOWEVER, that no such action shall be
               effective hereunder unless taken on or prior to the date 90 days
               after such record date.

        (c)    The Company, in the event of defaulted interest, shall set a
               special record date in accordance with Section 2.11.

SECTION 2.13.  CUSIP AND ISIN NUMBERS.

               The Company in issuing any series of Securities may use "CUSIP"
or "ISIN" numbers or both numbers, and, if so used, the Trustee shall use such
"CUSIP" or "ISIN"

                                       30
<Page>

numbers or both numbers in notices as a convenience to Holders; PROVIDED that
any such notice may state that no representation is made as to the correctness
of such numbers either as printed on such Securities or as contained in any
notice and that reliance may be placed only on the other identification numbers
printed on such Securities, and any such action relating to such notice shall
not be affected by any defect in or omission of such numbers in such notice. The
Company shall promptly notify the Trustee of any change in the "CUSIP" or "ISIN"
numbers.

                                   ARTICLE 3.

                                   REDEMPTION

SECTION 3.01.  NOTICES TO TRUSTEE.

               If the Company elects to redeem Securities of any series pursuant
to any optional redemption or change of control provisions thereof, it shall
notify the Trustee of the redemption date and the principal amount of Securities
of that series to be redeemed.

               The Company shall give the notice provided for in this Section at
least 45 days before the redemption date (unless a shorter notice period shall
be satisfactory to the Trustee), which notice shall specify the provisions of
such Security pursuant to which the Company elects to redeem such Securities.

               If the Company elects to reduce the principal amount of
Securities of any series to be redeemed pursuant to mandatory redemption
provisions thereof, it shall notify the Trustee of the amount of, and the basis
for, any such reduction. If the Company elects to credit against any such
mandatory redemption Securities it has not previously delivered to the Trustee
for cancellation, it shall deliver such Securities with such notice.

SECTION 3.02.  SELECTION OF SECURITIES TO BE REDEEMED.

               If less than all of any series of Securities are to be redeemed
at any time, the Trustee shall select Securities for redemption as follows:

               (1)  if the Securities are listed, in compliance with the
                    requirements of the principal national securities exchange
                    on which the Securities are listed; or

               (2)  if the Securities are not so listed, on a pro rata basis, by
                    lot or by such method as the Trustee shall deem fair and
                    appropriate.

               Except as otherwise provided as to any particular series of
Securities, Securities and portions thereof that the Trustee selects shall be in
amounts of more than $1,000. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Company promptly in writing of the
Securities or portions of Securities to be called for redemption.

                                       31
<Page>

SECTION 3.03.  NOTICE OF REDEMPTION.

               Except as otherwise provided as to any particular series of
Securities, at least 30 days but not more than 60 days before a redemption date,
the Company shall mail a notice of redemption to each Holder whose Securities
are to be redeemed at the address of such Holder as it appears in the Register
of Securities referred to in Section 2.03. Notices of redemption shall not be
conditional.

               If any Security is to be redeemed in part only, the notice of
redemption that relates to that Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion of the original Security shall be issued in the
name of the Holder thereof upon cancellation of the original Security.

               The notice shall identify the Securities of the series to be
redeemed and shall state:

        (1)    the redemption date;

        (2)    the redemption price fixed in accordance with the terms of the
               Securities of the series to be redeemed, plus accrued interest,
               if any, to the date fixed for redemption (the "REDEMPTION
               PRICE");

        (3)    if any Security is being redeemed in part, the portion of the
               principal amount of such Security to be redeemed and that, after
               the redemption date, upon surrender of such Security, a new
               Security or Securities in principal amount equal to the
               unredeemed portion shall be issued;

        (4)    the name and address of the Paying Agent;

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

        (6)    that, unless the Company defaults in payment of the redemption
               price, interest on Securities called for redemption ceases to
               accrue on and after the redemption date; and

        (7)    the CUSIP number or ISIN number, if any, of the Securities to be
               redeemed.

               At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense. The notice mailed in the
manner herein provided shall be conclusively presumed to have been duly given
whether or not the Holder receives such notice. In any case, failure to give
such notice by mail or any defect in the notice of the Holder of any Security
shall not affect the validity of the proceeding for the redemption of any other
Security.

SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.

               Once notice of redemption is mailed in accordance with Section
3.03, Securities called for redemption become due on the date fixed for
redemption. Upon surrender to the

                                       32
<Page>

Paying Agent, such Securities shall be paid at the redemption price. On and
after the redemption date, interest ceases to accrue on the Securities or
portions of them called for redemption.

SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.

               On or before 10:00 a.m. New York City time on the redemption
date, the Company shall deposit with the Paying Agent (or, if the Company or any
Affiliate is the Paying Agent, shall segregate and hold in trust) money
sufficient to pay the redemption price of all Securities called for redemption
on that date other than Securities that have previously been delivered by the
Company to the Trustee for cancellation. The Paying Agent shall return to the
Company any money not required for that purpose.

SECTION 3.06.  SECURITIES REDEEMED IN PART.

               Upon surrender of a Security that is redeemed in part, the
Company shall issue and the Trustee shall authenticate for the Holder at the
expense of the Company a new Security of same series equal in principal amount
to the unredeemed portion of the Security surrendered.

PROVIDED,

                                       33

HOWEVER, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of

written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency. The Company hereby

other provisions of TIA Section 314(a).

SECTION 4.08.  CALCULATION OF ORIGINAL ISSUE DISCOUNT.

(other than by lease) of all or substantially all of the assets of the Company
in accordance with Section 5.01 hereof, the successor corporation formed by such
consolidation or into which the Company is merged or to which such transfer is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Company under this Indenture with the same effect as if such
successor corporation had been named as the Company herein. In the event of any
such

                                       36

the predecessor Company may be dissolved, wound up or liquidated at any time
thereafter.

                              DEFAULTS AND REMEDIES

SECTION 6.01.  EVENTS OF DEFAULT.

               An "EVENT OF DEFAULT" occurs with respect to Securities of any
particular series if, unless in the establishing Board Resolution, Officers'
Certificate or supplemental indenture hereto, it is provided that such series
shall not have the benefit of said Event of Default:

        (1)    the Company defaults in the payment of interest on, or Liquidated
               Damages, if any, with respect to, any Security of that series
               when the same becomes due and payable and the default continues
               for a period of 30 days;

        (2)    the Company defaults in the payment of the Principal of
               Securities of that series when the same becomes due and payable
               at maturity, upon redemption or otherwise;

        (3)    failure by OI Group or any of its Restricted Subsidiaries for 60
               days after notice to comply with any of the other agreements in

               Securities of that series (with respect to any Guarantor) and the
               Collateral Documents (with respect to any Restricted Subsidiary
               which has pledged assets or property to secure its obligations
               under this Indenture and any series of Securities);

        (4)    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 OI Group or any Restricted
               Subsidiary (or the payment of which is guaranteed by OI Group or
               any of its Restricted Subsidiaries) whether such Indebtedness or
               Guarantee now exists, or is created after the date of this
               Indenture, if that default:

               (a)  is caused by a failure to pay principal of, or interest on
                    such Indebtedness prior to the expiration of the grace
                    period provided in such Indebtedness on the date of such
                    default (a "PAYMENT DEFAULT"); or

               (b)  results in the acceleration of such Indebtedness prior to
                    its express maturity; PROVIDED, that an Event of Default
                    shall not be deemed to occur with respect to any such
                    accelerated Indebtedness which is repaid or prepaid within
                    20 Business Days after such declaration;

               and, in any individual case, the principal amount of any such
               Indebtedness is equal to or in excess of $50.0 million, or such
               Indebtedness together with the principal amount of any other such
               Indebtedness under which there has been a

               aggregates $100.0 million or more;

        (5)    any final judgment or order for payment of money in excess of
               $50.0 million in any individual case and $100.0 million in the
               aggregate at any time shall be rendered against OI Group or any
               of its Restricted Subsidiaries and such judgment shall not have
               been paid, discharged or stayed for a period of 60 days;

        (6)    except as permitted by this Indenture or the Collateral
               Documents, any Guarantee of any Security of that series shall be
               held in any judicial proceeding to be unenforceable or invalid or
               shall cease for any reason to be in full force and effect or any
               Guarantor, or any Person acting on behalf of any Guarantor, shall
               deny or disaffirm its obligations under its Guarantee of any
               Security of that series;

        (7)    the Company, OI Group or any Significant Subsidiary of OI Group
               pursuant to or within the meaning of any Bankruptcy Law:

               (a)  commences a voluntary case;

               (b)  consents to the entry of an order for relief against it in

               (c)  consents to the appointment of a Custodian of it or for all
                    or substantially all of its property;

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

               (e)  admits in writing its inability generally to pay its debts
                    as the same become due;

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

               (a)  is for relief against the Company, OI Group or any
                    Significant Subsidiary of OI Group in an involuntary case;

               (b)  appoints a Custodian of the Company, OI Group or any
                    Significant Subsidiary of OI Group or for all or

               (c)  orders the liquidation of the Company, OI Group or any

               and the order or decree remains unstayed and in effect for 60
               days;

        (9)    except as permitted by the Collateral Documents, any amendments
               thereto and the provisions of this Indenture, any of the
               Collateral Documents ceases to be in full force and effect or
               ceases to be effective, in all material respects, to create the
               Lien

                                       38
<Page>

               purported to be created in the Collateral in favor of the holders
               of any Securities of that series for 60 days after notice; and

        (10)   any other Event of Default provided with respect to Securities of
               that series which is specified in a Board Resolution, Officers'
               Certificate or supplemental indenture establishing that series of
               Securities;

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

               Pursuant to Section 4.04, forthwith upon becoming aware of any
Default or Event of Default, the Company shall deliver to the Trustee an
Officers' Certificate specifying such Default or Event of Default and what
action the Company is taking or proposes to take with respect thereto

SECTION 6.02.  ACCELERATION.

               If an Event of Default with respect to Securities of any series
other than an Event of Default specified in clauses (7) and (8) of Section 6.01,
occurs and is continuing, the Trustee by notice to the Company, or the Holders
of at least 25% in principal amount of the then outstanding Securities of that
series by notice to the Company and the Trustee, may declare the unpaid
Principal (or, in the case of Original Issue Discount Securities, such lesser
amount as may be provided for in such Securities) of and any accrued and unpaid
interest on all the Securities of that series to be due and payable immediately.
Upon such declaration the Principal (or such lesser amount) and interest shall
be due and payable immediately. If an Event of Default specified in clause (7)
or (8) of Section 6.01 occurs, all outstanding Securities shall become and be
due and payable immediately without any declaration, act or notice. The Holders
of a majority in principal amount of the then outstanding Securities of that
series by notice to the Trustee may, on behalf of the Holders of all of the
Securities of that series, rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default with respect to that series have been cured or waived except
nonpayment of Principal (or such lesser amount) or interest that has become due
solely because of the acceleration.

SECTION 6.03.  OTHER REMEDIES.

               If an Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may pursue any available remedy to collect
the payment of Principal or interest on the Securities of that series or to
enforce the performance of any provision of the Securities of that series 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. All remedies are
cumulative to the extent permitted by law.

                                       39
<Page>

SECTION 6.04.  WAIVER OF PAST DEFAULTS.

               Subject to Section 9.02, the Holders of a majority in principal
amount of the then outstanding Securities of any series, by notice to the
Trustee, may waive an existing Default or Event of Default with respect to that
series and its consequences under this Indenture except a continuing Default or
Event of Default in the payment of interest or Liquidated Damages on, or the
Principal of any Security of that series (PROVIDED, HOWEVER, that the Holders of
a majority in principal amount of the outstanding Securities of any series may
rescind an acceleration and its consequences, including any related payment
default that resulted from such acceleration).

SECTION 6.05.  CONTROL BY MAJORITY.

               The Holders of a majority in principal amount of the then
outstanding Securities of any series may direct the time, method and place of
conducting any proceeding for any remedy with respect to that series available
to the Trustee or exercising any trust or power conferred on it. However, the
Trustee may refuse to follow any direction that conflicts with law or this
Indenture, that is unduly prejudicial to the rights of another Holder of
Securities of that series, or that may involve the Trustee in personal
liability. The Trustee may take any other action which it deems proper that is
not inconsistent with any such direction.

SECTION 6.06.  LIMITATION ON SUITS.

               A Holder of Securities of any series may not pursue a remedy with
respect to this Indenture, the Securities of any series, any Guarantee of
Securities or any Collateral Documents, if any, unless:

        (a)    the Holder gives to the Trustee written notice of a continuing
               Event of Default with respect to that series;

        (b)    the Holders of at least 25% in principal amount of the then
               outstanding Securities of that series make a written request to
               the Trustee to pursue the remedy;

        (c)    such Holder or Holders offer to the Trustee indemnity
               satisfactory to the Trustee against any loss, liability or
               expense;

        (d)    the Trustee does not comply with the request within 30 days after
               receipt of the request and the offer and, if requested, the
               provision of indemnity; and

        (e)    during such 30-day period the Holders of a majority in principal
               amount of the then outstanding Securities of that series do not
               give the Trustee a direction inconsistent with the request.

               The Trustee may withhold from Holders notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of Principal or interest or Liquidated Damages) if it determines
that withholding notice is in the interest of such Holders.

                                       40
<Page>

               No Holder of any series of Securities may use this Indenture to
prejudice the rights of another Holder of Securities of that series or to obtain
a preference or priority over another Holder of Securities of that series.

SECTION 6.07.  RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

               Notwithstanding any other provision of this Indenture, the right
of any Holder of a Security to receive payment of Principal of and interest, if
any, on the Security, on or after the respective due dates expressed in the
Security, 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
the Holder; PROVIDED that a Holder shall not have the right to institute any
such suit for the enforcement of payment if and to the extent that the
institution or prosecution thereof or the entry of judgment therein would, under
applicable law, result in the surrender, impairment, waiver or loss of the Lien
of this Indenture upon any property subject to such Lien.

SECTION 6.08.  COLLECTION SUIT BY TRUSTEE.

               If an Event of Default specified in Section 6.01(1) or (2) occurs
and is continuing with respect to Securities of any series, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount of Principal (or such portion of the Principal as
may be specified as due upon acceleration at that time in the terms of that
series of Securities) and interest, if any, remaining unpaid on the Securities
of that series then outstanding, together with (to the extent lawful) interest
on overdue Principal and interest, and such further amount as shall be
sufficient to cover the costs and, to the extent lawful, expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel and any other amounts due the Trustee under
Section 7.07.

SECTION 6.09.  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 (or any other obligor on the Securities), its creditors or its property
and shall be entitled to and empowered to collect and receive any money or other
property payable or deliverable on any such claims and to distribute the same,
and any custodian in any such judicial proceedings is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agent and counsel, and any other
amounts due the Trustee under Section 7.07. Nothing contained herein shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 6.10.  PRIORITIES.

               If the Trustee collects any money with respect to Securities of
any series pursuant to this Article (including without limitation any amounts
received in accordance with the terms of the Intercreditor Agreement), it shall
pay out the money in the following order:

               First:    to the Trustee, its agents and attorneys for amounts
                         due under Section 7.07, including payment of all
                         compensation, expense and liabilities incurred, and all
                         advances made, by the Trustee and the costs and
                         expenses of collection;

               Second:   to Holders for amounts due and unpaid on the Securities
                         of such series for Principal and interest, ratably,
                         without preference or priority of any kind, according
                         to the amounts due and payable on the Securities of
                         such series for Principal and interest, respectively;
                         and

               Third:    to the Company or to such party as a court of competent
                         jurisdiction shall direct; PROVIDED, however, that in
                         the case of amounts received from the distribution of
                         payments pursuant to the Intercreditor Agreement or any
                         other proceeds of Collateral securing any series of
                         Securities, such amounts shall not be distributed to
                         the Company but shall rather be held by the Trustee, in
                         trust, for subsequent application in accordance with
                         the Securities of such series and this Indenture to the
                         payment of Principal of and interest on the Securities
                         upon the earlier to occur of (i) any scheduled or
                         mandatory payment of Principal, optional redemption or
                         payment of accrued interest on the Securities of such
                         series, in any such case as directed in writing by the
                         Company, and (ii) the acceleration of the maturity of
                         the Securities of that series pursuant to Section 6.02
                         (including an acceleration by reason of an Event of
                         Default specified in Section 6.01 (7) or (8)). Until so
                         applied, such payments shall be held in a separate
                         account, in trust, by the Trustee or invested by the
                         Trustee at the written direction of the Company. At
                         such time as no Securities of any series remain
                         outstanding, any excess money held by the Trustee shall
                         be paid to the Company.

               The Trustee may fix a record date and payment date for any
payment to Holders of Securities of any series pursuant to this Section. The
Trustee shall notify the Company in writing reasonably in advance of any such
record date and payment date.

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 a 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

                                       42
<Page>

faith of the claims or defense made by the party litigant. This Section does not
apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a
suit by Holders of more than 10% in principal amount of the then outstanding
Securities of any series.

                                   ARTICLE 7.

                                     TRUSTEE

SECTION 7.01.  DUTIES OF TRUSTEE.

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

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

               (i)   the duties of the Trustee shall be determined solely by the
                     express provisions of this Indenture or the TIA and the
                     Trustee need perform only those duties that are
                     specifically set forth in this Indenture or the TIA and no
                     others, and no implied covenants or obligations shall be
                     read into this Indenture against the Trustee; and

               (ii)  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,
                     the Trustee shall examine the certificates and opinions to
                     determine whether or not they conform 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 liabilities for its own
               negligent action, its own negligent failure to act, or its own
               willful misconduct, except that:

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

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

               (iii) 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 6.05.

        (d)    Whether or not therein expressly so provided, every provision of
               this Indenture that in any way relates to the Trustee is subject
               to paragraphs (a), (b) and (c) of this Section.

                                       43
<Page>

        (e)    No provision of this Indenture shall require the Trustee to
               expend or risk its own funds or incur any liability. The Trustee
               may refuse to perform any duty or exercise any right or power
               unless it receives security and indemnity satisfactory to it
               against any loss, liability or expense.

        (f)    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. Absent written instruction from the Company, the
               Trustee shall not be required to invest any such money. Money
               held in trust by the Trustee need not be segregated from other
               funds except to the extent required by law.

SECTION 7.02.  RIGHTS OF TRUSTEE.

               Subject to TIA Section 315(a) through (d):

        (a)    The Trustee may rely on any document believed by it to be genuine
               and to have been signed or presented by the proper person. The
               Trustee shall not be bound to make any investigation into the
               facts or matters stated in any resolution, certificate,
               statement, instrument, opinion, report, notice, request,
               direction, consent, order, bond, debenture, note, other evidence
               of indebtedness or other paper or document, but the Trustee, in
               its discretion, may make such further inquiry or investigation
               into such facts or matters as it may see fit.

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

        (c)    The Trustee may act through 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 under this Indenture, unless the
               Trustee's conduct constitutes negligence.

        (e)    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.

        (f)    The Trustee may consult with counsel of its selection and may
               rely upon the advice of such counsel or any Opinion of Counsel.

        (g)    The Trustee shall not be deemed to have notice of any Default or
               Event of Default unless a Trust Officer of the Trustee has actual
               knowledge thereof or unless written notice of any event that is
               in fact such a default is received by the Trustee at the
               Corporate Trust Office of the Trustee, and such notice references
               the Securities generally or the Securities of a particular
               series, as the case may be, and this Indenture.

                                       44
<Page>

        (h)    Except with respect to Sections 4.03 and 4.04, the Trustee shall
               have no duty to inquire as to the performance of the Company with
               respect to the covenants contained in Article Four.

        (i)    Delivery of reports, information and documents to the Trustee
               under Article 4 (other than the delivery of Officers'
               Certificates pursuant to Section 4.04) is for informational
               purposes only and the Trustees' receipt of the foregoing shall
               not constitute constructive notice of any information contained
               therein or determinable from information contained therein,
               including the Company's compliance with any of their covenants
               hereunder (as to which the Trustee is entitled to rely
               conclusively on Officers' Certificates).

SECTION 7.03.  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 an
Affiliate with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. However, the Trustee is subject to TIA
Sections 310(b) and 311.

SECTION 7.04.  TRUSTEE'S DISCLAIMER.

               The Trustee 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 in the Securities other than its certificate of
authentication.

SECTION 7.05.  NOTICE OF DEFAULTS.

               If a Default or Event of Default with respect to the Securities
of any series occurs and is continuing and if it is known to the Trustee, the
Trustee shall mail to all Holders of Securities of that series a notice of the
Default or Event of Default within 60 days after it occurs. Except in the case
of a Default or Event of Default in payment on any such Security, the Trustee
may withhold the notice if and so long as a committee of its Trust Officers in
good faith determines that withholding the notice is in the interests of such
Holders.

SECTION 7.06.  REPORTS BY TRUSTEE TO HOLDERS.

               Within 60 days after May 15 in each year, the Trustee with
respect to any series of Securities shall mail to Holders of Securities of that
series as provided in TIA Section 313(c) a brief report dated as of such May 15
that complies with TIA Section 313(a) (if such report is required by TIA Section
313(a)). The Trustee shall also comply with TIA Section 313(b).

               A copy of each report at the time of its mailing to Holders shall
be mailed to the Company and filed with the Commission and each stock exchange
on which any of the Securities are listed, as required by TIA Section 313(d).
The Company shall notify the Trustee when the Securities are listed on any stock
exchange.

                                       45
<Page>

SECTION 7.07.  COMPENSATION AND INDEMNITY.

               The Company shall pay to the Trustee from time to time such
compensation as shall be agreed upon in writing for its services hereunder. The
Company shall reimburse the Trustee upon written request for all reasonable
out-of-pocket expenses incurred by it. Such expenses shall include the
reasonable compensation and out-of-pocket expenses of the Trustee's agents and
counsel.

               The Company shall indemnify each of the Trustee or any
predecessor Trustee for any loss, liability, damage, claims or expenses,
including taxes (other than taxes based upon, measured by or determined by the
income of the Trustee) incurred by it, without negligence or bad faith on its
part, in connection with the administration of this Indenture and its duties
hereunder. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. The Company shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not
pay for any settlement made without its consent.

               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 in its capacity as Trustee, except money or property
held in trust to pay Principal and interest on particular Securities. Such lien
shall survive the satisfaction and discharge of this Indenture.

               If the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(4) or (5) occurs, the expenses and the
compensation for the services shall be intended to constitute expenses of
administration under any applicable Bankruptcy Law.

               This Section 7.07 shall survive the termination of this
Indenture.

SECTION 7.08.  REPLACEMENT OF TRUSTEE.

               A resignation or removal of the Trustee with respect to one or
more or all series of Securities and appointment of a successor Trustee shall
become effective only upon the successor Trustee's acceptance of appointment as
provided in this Section.

               The Trustee may resign with respect to one or more or all series
of Securities by 30 days notice to the Company in writing. The Holders of a
majority in principal amount of the then outstanding Securities of any series
may remove the Trustee as to that series by so notifying the Trustee in writing
and may appoint a successor Trustee with the Company's consent. The Company may
remove the Trustee with respect to one or more or all series of Securities if:

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

               (2)  the Trustee is adjudged a bankrupt or an insolvent;

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

                                       46
<Page>

               (4)  the Trustee becomes incapable of acting.

               If, as to any series of Securities, the Trustee resigns or is
removed or if a vacancy exists in the office of Trustee for any reason, the
Company shall promptly appoint a successor Trustee for that series. Within one
year after the successor Trustee with respect to any series takes office, the
Holders of a majority in principal amount of the then outstanding Securities of
that series may appoint a successor Trustee to replace the successor Trustee
appointed by the Company. If a successor Trustee as to a particular series does
not take office within 60 days after the retiring Trustee resigns or is removed,
the retiring Trustee, the Company or the Holders of at least 10% in principal
amount of the then outstanding Securities of that series may petition any court
of competent jurisdiction for the appointment of a successor Trustee.

               If the Trustee fails to comply with Section 7.10 with respect to
any series, any Holder of Securities of that series who satisfies the
requirements of TIA Section 310(b) may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee for that series.

               A successor Trustee as to any series of Securities shall deliver
a written acceptance of its appointment to the retiring Trustee and to the
Company. Immediately after that, 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 7.07), 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 as to that series.
The successor Trustee shall mail a notice of its succession to the Holders of
Securities of that series.

               Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring trustee.

               In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and that (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
shall contain such provisions as shall be necessary or desirable to confirm that
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series as to which the retiring Trustee is
not retiring shall continue to be vested in the retiring Trustee, and (3) shall
add to or change any of the provisions of this Indenture as shall be necessary
or desirable to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee; PROVIDED, HOWEVER, that nothing herein or in
such supplemental Indenture shall constitute such Trustee co-trustees of the
same trust and that each such Trustee shall be trustee of a trust hereunder
separate and apart from any trust hereunder administered by any other such
Trustee.

               Upon the execution and delivery of such supplemental Indenture
the resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each

                                       47
<Page>

such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates.

SECTION 7.09.  SUCCESSOR TRUSTEE BY MERGER, ETC.

               If the Trustee as to any series of Securities consolidates,
merges or converts into, or transfers all or substantially all of its corporate
trust business to, another corporation, the successor corporation without any
further act shall be the successor Trustee as to that series; PROVIDED that such
corporation shall be eligible under this Article 7 and TIA Section 310(a).

SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.

               Each series of Securities shall always have a Trustee who
satisfies the requirements of TIA Section 310(a)(1), (2) and (5). The Trustee as
to any series of Securities shall always have a combined capital and surplus of
at least $25,000,000 as set forth in its most recent published annual report of
condition. The Trustee is subject to TIA Section 310(b).

SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

               The Trustee is subject to 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
therein. If the Trustee acquires any conflicting interest as defined in the TIA
it shall eliminate such conflict within 90 days, apply to the Commission for
permission to continue or resign.

                                   ARTICLE 8.

                     SATISFACTION AND DISCHARGE; DEFEASANCE

SECTION 8.01.  SATISFACTION AND DISCHARGE OF INDENTURE.

               The provisions of this Indenture shall upon Company Order cease
to be of further effect (except as to any surviving rights of registration of
transfer or exchange of Securities herein expressly provided for), and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture with respect to a
particular series of Securities; when

        (a)    either:

               (i)  all Securities of that series that have been authenticated
                    and delivered (except lost, stolen or destroyed Securities

               Counsel reasonably acceptable to the Trustee confirming that (a)
               the Company has received from, or there has been published by,
               the Internal Revenue Service a ruling, or (b) since the date of

               applicable Federal income tax law, in either case to the effect
               that, and based thereon such Opinion of Counsel shall confirm
               that, the Holders of the Securities of such series shall not
               recognize income, gain or loss for Federal income tax purposes as

               to be applied to such deposit); or (b) insofar as Events of
               Default from bankruptcy or insolvency events are concerned, at
               any time in the period ending on the 91st day after the date of
               deposit;

        (4)    such defeasance pursuant to this Section 8.03 shall not result in
               a breach or violation of, or constitute a default under any
               material agreement or instrument to which OI Group or the Company
               or any of their Restricted Subsidiaries are a party or by which
               OI Group or the Company or any of such Restricted Subsidiaries

               "insider" of the Company under applicable bankruptcy law, after
               the 91st day following the deposit, the trust funds shall not be

               reorganization or similar laws affecting creditors' rights
               generally;

               Certificate stating that the deposit was not made by the Company
               with the intent of preferring the Holders of any series of
               Securities over the other creditors of the Company with the
               intent of defeating, hindering, delaying or defrauding creditors
               of the Company or others; and

indenture hereto for a particular series of Securities or a Board Resolution or
an Officers' Certificate delivered pursuant to Section 2.01 (and the failure to

        (10)   amend or modify any of the provisions of the Collateral Documents
               except (a) in accordance with the terms of such documents or (b)
               as permitted by Section 9.01;

        (11)   make any change to this Section 9.02; or

        (12)   reduce the principal amount of Original Issue Discount Securities
               payable upon acceleration of the maturity thereof;

               An amendment or waiver under this Section 9.02 that waives,
changes or eliminates any covenant or other provision of this Indenture that has
expressly been included solely for the benefit of one or more particular series
of Securities, or that modifies the rights of the Holders of Securities of such
series with respect to such covenant or other provision, shall be deemed not to
affect the rights under this Indenture of the Holders of Securities of any other
series.

               It shall not be necessary for the consent of the Holders under
this Section 9.02 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

               After any amendment under this Indenture becomes effective, the
Company shall mail to the Holders a notice briefly describing such any
amendment. Any failure of the Company to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture or waiver. The Company shall mail supplemental
indentures to Holders upon request.

                                       55
<Page>

               Amendments to the Collateral Documents shall be made in
accordance with their terms.

SECTION 9.03.  REVOCATION AND EFFECT OF CONSENTS.

               Until an amendment or waiver becomes effective, a consent to it
by a Holder of a Security is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security, even if notation of the consent is not
made on any Security; PROVIDED, HOWEVER, that unless a record date shall have
been established pursuant to Section 2.12(a), any such Holder or subsequent
Holder may revoke the consent as to his Security or portion of a Security if the
Trustee receives the notice of revocation before the date on which the amendment
or waiver becomes effective. An amendment or waiver shall become effective on
receipt by the Trustee of consents from the Holders of the requisite percentage
principal amount of the outstanding Securities of any series, and thereafter
shall bind every Holder of Securities of that series.

SECTION 9.04.  NOTATION ON OR EXCHANGE OF SECURITIES.

               If an amendment or waiver changes the terms of a Security: (a)
the Trustee may require the Holder of the Security to deliver it to the Trustee,
the Trustee may, at the written direction of the Company and at the Company's
expense, place an appropriate notation on the Security about the changed terms
and return it to the Holder and the Trustee may place an appropriate notation on
any Security thereafter authenticated; or (b) 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.

SECTION 9.05.  TRUSTEE TO SIGN AMENDMENTS, ETC.

               The Trustee shall receive an Opinion of Counsel stating that the
execution of any amendment or waiver proposed pursuant to this Article is
authorized or permitted by this Indenture. Subject to the preceding sentence,
the Trustee shall sign such amendment or waiver. The Trustee may, but shall not
be obligated to, execute any such amendment, supplement or waiver that affects
the Trustee's own rights, duties, liabilities or immunities under this
Indenture.

                                   ARTICLE 10.

                                    GUARANTEE

SECTION 10.01. GUARANTEE.

               Subject to the provisions of this Article 10, the Guarantors
hereby, jointly and severally, unconditionally and irrevocably, guarantee to
each Holder and to the Trustee and its successors and assigns (a) the due and
punctual payment of Principal of, interest on and Liquidated Damages, if any,
with respect to the Securities of any series to which this Article 10 is
applicable when due, whether at Stated Maturity, by acceleration, by redemption
or otherwise, and all other monetary obligations of the Company under this
Indenture (including obligations to the Trustee) with respect to such Securities
and (b) the due and punctual performance within applicable grace periods of all
other obligations of the Company under this Indenture with

                                       56
<Page>

respect to such Securities (all the foregoing being hereinafter collectively
called the "OBLIGATIONS"). The Guarantors further agree that the Obligations may
be extended or renewed, in whole or in part, without notice or further assent
from the Guarantors, and that the Guarantors will remain bound under this
Article 10 notwithstanding any extension or renewal of any Obligation.

               The Guarantors waive presentation to, demand of, payment from and
protest to the Company of any of the Obligations and also waive notice of
protest for nonpayment. The Guarantors waive notice of any default under the
Securities of such series to which this Article 10 is applicable or the
Obligations with respect thereto. The obligations of the Guarantors under this
Section 10.01 shall not be affected by (a) the failure of any Holder or the
Trustee to assert any claim or demand or to enforce any right or remedy against
the Company or any other Person under this Indenture, the Securities of such
series or any other agreement or otherwise; (b) any extension or renewal of any
Obligation; (c) any rescission, waiver, amendment, modification or supplement of
any of the terms or provisions of this Indenture (other than this Article 10),
the Securities of such series or any other agreement, unless such rescission,
waiver, amendment, modification or supplement expressly affects the obligations
of any Guarantor under this Section 10.01; (d) the release of any security held
by any Holder or the Trustee for the Obligations or any of them; (e) the failure
of any Holder or Trustee to exercise any right or remedy against any other
guarantor of the Obligations; or (f) any change in the ownership of the Company.

               The Guarantors further agree that their Guarantees herein
constitute a guarantee of payment, performance and compliance when due (and not
a guarantee of collection) and waive any right to require that any resort be had
by any Holder or the Trustee to any security held for payment of the
Obligations.

               Except as set forth in this Indenture, the obligations of the
Guarantors hereunder shall not be subject to any reduction, limitation,
impairment or termination for any reason, including any claim of waiver,
release, surrender, alteration or compromise, and shall not be subject to any
defense, setoff, counterclaim, recoupment or termination whatsoever or by reason
of the invalidity, illegality or unenforceability of the Obligations or
otherwise. Without limiting the generality of the foregoing, except as set forth
in this Indenture, the obligations of the Guarantors herein shall not be
discharged or impaired or otherwise affected by the failure of any Holder or the
Trustee to assert any claim or demand or to enforce any remedy under this
Indenture, the Securities of any applicable series or any other agreement, by
any waiver or modification of any thereof, by any default, failure or delay,
willful or otherwise, in the performance of the Obligations with respect to such
Securities, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of
the Guarantors or would otherwise operate as a discharge of the Guarantors as a
matter of law or equity.

               The Guarantors further agree that their Guarantees herein shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any Obligation with respect to such Securities
is rescinded or must otherwise be restored by any Holder or the Trustee upon the
bankruptcy or reorganization of the Company or otherwise, unless such Guarantee
has been released in accordance with Section 10.10.

                                       57
<Page>

               In furtherance of the foregoing and not in limitation of any
other right which any Holder or the Trustee has or may have at law or in equity
against the Guarantors by virtue hereof, upon the failure of the Company to pay
any Obligation with respect to such Securities when and as the same shall become
due, whether at Stated Maturity, by acceleration, by redemption or otherwise, or
to perform or comply with any other Obligation with respect to such Securities,
the Guarantors hereby promise to and will, upon receipt of written demand by the
Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the
Trustee an amount equal to the sum of (i) the unpaid Principal amount of such
Obligations, (ii) accrued and unpaid interest on such Obligations (but only to
the extent not prohibited by law) and (iii) all other monetary Obligations of
the Company to the Holders of such Securities and the Trustee.

               The Guarantors agree that, as between the Guarantors, on the one
hand, and the Holders and the Trustee, on the other hand, (x) the maturity of
the Obligations guaranteed hereby may be accelerated as provided in Article 6
for the purposes of the Guarantee herein, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the Obligations
guaranteed hereby, and (y) in the event of any declaration of acceleration of
such Obligations as provided in Article 6, such Obligations (whether or not due
and payable) shall forthwith become due and payable by the Guarantors for the
purposes of this Section.

               The Guarantors also agree to pay any and all costs and expenses
(including reasonable attorneys' fees and expenses) incurred by the Trustee or
any Holder in enforcing any rights under this Section.

SECTION 10.02. LIMITATION ON LIABILITY.

               Any term or provision of this Indenture to the contrary
notwithstanding, the obligations of each Guarantor are limited to the maximum
amount as will result in the Obligations of such Guarantor under the Guarantee
not constituting a fraudulent conveyance or fraudulent transfer under federal or
state law.

SECTION 10.03. EXECUTION AND DELIVERY OF GUARANTEE.

               To evidence its Guarantee set forth in Section 10.01, each
Guarantor hereby agrees that a notation of such Guarantee substantially in the
form included in Exhibit C shall be endorsed by an Officer of such Guarantor on
each Security authenticated and delivered by the Trustee to which this Article
10 is applicable and that this Indenture shall be executed on behalf of such
Guarantor by its President, any Executive or Senior Vice President, Treasurer,
Assistant Treasurer or one of its Vice Presidents. Further, the Company shall
cause all future Guarantors to execute a supplemental indenture.

               Each Guarantor hereby agrees that its Guarantee set forth in
Section 10.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Security to which this Article 10 is applicable a notation of
such Guarantee.

               If an Officer whose signature is on this Indenture or on the
Guarantee no longer holds that office at the time the Trustee authenticates the
Security on which a Guarantee is endorsed, the Guarantee shall be valid
nevertheless.

                                       58
<Page>

               The delivery of any Security to which this Article 10 is
applicable by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Guarantee set forth in this Indenture on behalf
of the Guarantors.

SECTION 10.04. SUCCESSORS AND ASSIGNS.

               This Article 10 shall inure to the benefit of the successors and
assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges
conferred upon that party in this Indenture and in the Securities shall
automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions of this Indenture.

SECTION 10.05. NO WAIVER.

               Neither a failure nor a delay on the part of either the Trustee
or the Holders in exercising any right, power or privilege under this Article 10
shall operate as a waiver thereof, nor shall a single or partial exercise
thereof preclude any other or further exercise of any right, power or privilege.
The rights, remedies and benefits of the Trustee and the Holders herein
expressly specified are cumulative and not exclusive of any other rights,
remedies or benefits which either may have under this Article 10 at law, in
equity, by statute or otherwise.

SECTION 10.06. RIGHT OF CONTRIBUTION.

               Each Guarantor hereby agrees that to the extent that a Guarantor
shall have paid more than its proportionate share of any payment made hereunder,
such Guarantor shall be entitled to seek and receive contribution from and
against any other Guarantor hereunder who has not paid its proportionate share
of such payment. Each Guarantor's right of contribution shall be subject to the
terms and conditions of Section 10.07. The provisions of this Section shall in
no respect limit the obligations and liabilities of any Guarantor to the Trustee
and the Holders and each Guarantor shall remain liable to the Trustee and the
Holders for the full amount guaranteed by such Guarantor hereunder.

SECTION 10.07. NO SUBROGATION.

               Notwithstanding any payment or payments made by any of the
Guarantors hereunder, no Guarantor shall be entitled to be subrogated to any of
the rights of the Trustee or any Holder against the Company or any other
Guarantor or any collateral security or guarantee or right of offset held by the
Trustee or any Holder for the payment of the Obligations, nor shall any
Guarantor seek or be entitled to seek any contribution or reimbursement from the
Company or any other Guarantor in respect of payments made by such Guarantor
hereunder, until all amounts owing to the Trustee and the Holders by the Company
on account of the Obligations are paid in full. If any amount shall be paid to
any Guarantor on account of such subrogation rights at any time when all of the
Obligations shall not have been paid in full, such amount shall be held by such
Guarantor in trust for the Trustee and the Holders, segregated from other funds
of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be
turned over to the Trustee in the exact form received by such Guarantor (duly
indorsed by such Guarantor to the Trustee, if required), to be applied against
the Obligations.

                                       59

SECTION 10.08. ADDITIONAL GUARANTORS; REINSTATEMENT OF GUARANTEES.

               Until such time as all Guarantees by the Guarantors under this
Indenture shall have been released in accordance with Section 10.10, OI Group
shall cause each Domestic Subsidiary of OI Group or any of its Domestic
Subsidiaries that guarantees the Company's Indebtedness under the Credit
Agreement, including the reinstatement or renewal of a Guarantee of Indebtedness
under the Credit Agreement previously released under the Credit Agreement, to
execute and deliver a supplement to this Indenture providing that such Domestic
Subsidiary will be a Guarantor hereunder within 10 Business Days of the date on
which it executes a guarantee under the Credit Agreement; PROVIDED that all
Subsidiaries that have properly been designated as Unrestricted Subsidiaries in
accordance with this Indenture (i) shall not be required to execute or maintain
a Guarantee and (ii) shall be released from all Obligations under any Guarantee,
in each case for so long as they continue to constitute Unrestricted
Subsidiaries. Domestic Subsidiaries that are Guarantors on the date any such
supplement is executed by an additional Domestic Subsidiary shall not be
required to become parties to such supplement and hereby agree to the execution
and delivery by any additional Domestic Subsidiary of any such supplement.

SECTION 10.09. MODIFICATION.

               No modification, amendment or waiver of any provision of this
Article 10, nor the consent to any departure by the Guarantors therefrom, shall
in any event be effective unless the same shall be in writing and signed by the
Trustee, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given; it being understood that the
release of the Guarantees of Guarantors pursuant to Section 10.10 shall not be
an amendment or waiver of any provision of this Article 10 and shall not require
any action on the part of the Trustee. No notice to or demand on the Guarantors
in any case shall entitle the Guarantors to any other or further notice or
demand in the same, similar or other circumstances.

SECTION 10.10. RELEASE OF GUARANTOR.

        (a)    A Guarantor shall be automatically released without any action on
               the part of the Trustee of the Holders from its obligations under
               this Indenture and Guarantee if OI Group properly designates any
               Restricted Subsidiary that is a Guarantor as an Unrestricted
               Subsidiary.

        (b)    Upon the release of a Guarantee by a Domestic Subsidiary under
               the Credit Agreement, the Guarantee of such Domestic Subsidiary
               under this Indenture will be released and discharged at such time
               and the Trustee shall execute an appropriate instrument
               evidencing such release. If any such Domestic Subsidiary
               thereafter guarantees obligations under the Credit Agreement (or
               any released Guarantee under the Credit Agreement is reinstated
               or renewed), then such Domestic Subsidiary will guarantee the
               Securities in accordance with this Article 10.

SECTION 10.11. MERGER, CONSOLIDATION AND SALE OF ASSETS OF A GUARANTOR.

               A Guarantor may not sell or otherwise dispose of all or
substantially of its assets to, or consolidate with or merge with or into
(whether or not such Guarantor is the surviving Person), another Person, other
than the Company or another Guarantor, unless:

        (1)    immediately after giving effect to that transaction, no Event of
               Default shall have occurred and be continuing; and

        (2)    the Person acquiring the property in any such sale or disposition
               or the Person formed by or surviving any such consolidation or
               merger is organized or existing under the laws of the United
               States, any state thereof or the District of Columbia and assumes
               all the obligations of that Guarantor under this Indenture, its
               Guarantee, the Collateral Documents and the Registration Rights
               Agreement pursuant to a supplemental indenture satisfactory to
               the Trustee; and

        (3)    the Company shall have delivered to the Trustee an Officers'
               Certificate and an Opinion of Counsel, each stating that such
               consolidation, sale, lease or merger complies with the foregoing
               clauses (1) and (2).

               Notwithstanding the foregoing, each Guarantor may consolidate
with or merge into or sell its assets to the Company or another Guarantor.

                                   ARTICLE 11.

                             COLLATERAL AND SECURITY

SECTION 11.01. COLLATERAL DOCUMENTS.

               The due and punctual payment of the Principal of, and interest
and Liquidated Damages, if any, on the Securities of a series and the Guarantees
thereof when and as the same shall be due and payable, whether on an interest
payment date, at maturity, by acceleration, repurchase, redemption or otherwise,
interest on the overdue Principal of and interest (to the extent permitted by
law), if any, on the Securities of such series and the Guarantees thereof and
performance of all other obligations under this Indenture, including, without
limitation, the obligations of the Company set forth in Section 7.07 herein, and
the Securities of such series and the Guarantees thereof, shall be secured as
provided in the Collateral Documents. The Trustee, the Company and each
Guarantor hereby agree that the Collateral Agent shall hold the Collateral in
trust on a PARI PASSU basis with the Indebtedness of the Company under the
Credit Agreement, related documents and liabilities owing to lenders or
affiliates of lenders party to the Credit Agreement and in connection with
interest rate and currency agreements and certain other Indebtedness permitted
by the Credit Agreement, in each case subject and pursuant to the terms of the
Collateral Documents.

               Each Holder, by its acceptance of any Security and the Guarantees
thereof to which this Article is applicable, consents and agrees to the terms of
the Collateral Documents (including, without limitation, the provisions
providing for foreclosure and release of Collateral) as the same may be in
effect or may be amended from time to time in accordance with their

                                       61
<Page>

terms and authorizes and directs (i) the Collateral Agent, with respect to each
of the Collateral Documents to which it is a party and (ii) the Trustee, with
respect to the Collateral Documents and the Intercreditor Acknowledgment, to
perform their respective obligations and exercise their respective rights
thereunder in accordance therewith.

               The Trustee and each Holder, by accepting the Securities and the
Guarantees thereof, acknowledges that, as more fully set forth in the Collateral
Documents, the Collateral as now or hereafter constituted shall be held on a
PARI PASSU basis for the benefit of all the senior secured creditors under the
Collateral Documents, including, without limitation, the lenders under the
Credit Agreement and that the lien of this Indenture and the Collateral
Documents in respect of the Trustee and the Holders is subject to and qualified
and limited in all respects by the Collateral Documents and actions that may be
taken thereunder.

               As amongst the Holders of any Security and the Guarantees thereof
to which this Article is applicable, the Collateral as now or hereafter
constituted shall be held on a PARI PASSU basis for the benefit of the Holders
without preference, priority or distinction of any thereof over any other by
reason of difference in time of issuance, sale or otherwise, as security for the
Securities and the Guarantees thereof.

SECTION 11.02. OPINIONS.

               Promptly after the qualification of this Indenture under the TIA,
the Company shall deliver the opinion(s) required by Section 314(b)(1) of the
TIA. Subsequent to the execution and delivery of this Indenture, to the extent
required by the TIA, the Company shall furnish to the Trustee on or before each
anniversary of the date of qualification of this Indenture under the TIA, an
Opinion of Counsel, dated as of such date, stating either that (i) in the
opinion of such counsel, all action has been taken with respect to any filing,
re-filing, recording or re-recording with respect to the Collateral as is
necessary to maintain the Lien on the Collateral in favor of the Holders or (ii)
in the opinion of such counsel, that no such action is necessary to maintain
such Lien.

SECTION 11.03. RELEASE AND SUBSTITUTION OF COLLATERAL; AMENDMENT OF COLLATERAL
               DOCUMENTS.

               The parties hereto hereby agree and acknowledge that the
Collateral may be released by the Collateral Agent at any time in accordance
with the provisions of the Collateral Documents and, if applicable, the Credit
Agreement or upon the termination of the Credit Agreement and, in any such case,
the Collateral so released shall automatically be released as Collateral for the
Securities and the Guarantees thereof without any action on the part of the
Trustee or the Holders. When the obligations under the Credit Agreement have
been paid in full, when the collateral under the Collateral Documents no longer
secures the obligations under the Credit Agreement and upon election of the
applicable grantors or pledgors, or when OI Inc. and OI Group achieve the
investment grade ratings specified in the Credit Agreement and the Collateral
Agent acknowledges such ratings, each of the Collateral Documents may be
terminated and the Collateral securing the Securities and the Guarantees
thereunder, released. The Collateral Documents provide that upon release of a
Guarantee under this Indenture, the security interest in the assets of that
Guarantor securing the Securities and the Guarantees of the Securities will be
released simultaneously. Under the indemnification provisions contained in

                                       62
<Page>

the Intercreditor Agreement, any pro rata payments due to the Collateral Agent
from the Holders of the Securities will be deducted from their portion of the
proceeds from the Collateral prior to the distribution of such proceeds. The
amount of indebtedness secured under the Collateral Documents may be increased
without the consent of the Trustee or the Holders of the Securities.

               For purposes of the TIA, the release of any Collateral from the
terms of the Collateral Documents will not be deemed to impair the security
under this Indenture in contravention of the provisions hereof or affect the
Lien of this Indenture or the Collateral Documents if and to the extent the
Collateral is released pursuant to the terms of the Collateral Documents and, if
applicable, the Credit Agreement or upon the termination of the Credit
Agreement. The Trustee and each Holder of Securities and the Guarantees thereof
to which this Article 11 is applicable acknowledge that a release of Collateral
in accordance with the terms of the Collateral Documents and, if applicable, the
Credit Agreement or upon the termination of the Credit Agreement, as the case
may be, will not be deemed for any purpose to be an impairment of the security
under this Indenture. To the extent applicable, the Company shall cause TIA
Section 314(d) relating to the release of property or securities from the Lien
of the Collateral Documents and relating to the substitution therefor of any
property or securities to be subjected to the Lien of the Collateral Documents
to be complied with.

               The fair value of Collateral released from the Liens of the
Collateral Documents pursuant to the preceding paragraph shall not be considered
in determining whether the aggregate fair value of Collateral released from the
Liens of the Collateral Documents in any calendar year exceeds the 10% threshold
specified in Section 314(d)(l) of the TIA. It is expressly understood that
Section 11.04 and this Section 11.03 relate only to the Company's obligations
under the TIA and shall not restrict or otherwise affect the Company's and its
Subsidiaries' rights or abilities to release Collateral pursuant to the terms of
the Credit Agreement and the Collateral Documents or as otherwise permitted by
the lenders under the Credit Agreement.

SECTION 11.04. CERTIFICATES OF THE COMPANY.

               The Company shall furnish to the Trustee prior to each proposed
release of Collateral all documents required by TIA Section 314(d), if any. The
Trustee may, to the extent permitted by Sections 7.01 and 7.02, accept as
conclusive evidence of compliance with the foregoing provisions the appropriate
statements contained in such documents. Promptly after the receipt of any such
documents, the Trustee shall execute an appropriate instrument evidencing such
release. Any certificate or opinion required by TIA Section 314(d), if
applicable, may be made by an Officer of the Company except in cases where TIA
Section 314(d) requires that such certificate or opinion be made by an
independent engineer, appraiser or other expert within the meaning of TIA
Section 314(d).

SECTION 11.05. AUTHORIZATION OF ACTIONS TO BE TAKEN BY THE TRUSTEE UNDER THE
               COLLATERAL DOCUMENTS.

               The Trustee shall be the Representative (as such term is defined
in the Collateral Documents) on behalf of the Holders and shall act upon the
written direction of the Holders with regard to all voting, consent and other
rights granted to the Holders under the Collateral

                                       63
<Page>

Documents, if any. Subject to the provisions of the Collateral Documents and the
Intercreditor Acknowledgment, the Trustee may, in its sole discretion and
without the consent of the Holders, on behalf of the Holders, take all actions
it deems necessary or appropriate in order to (a) enforce any of its rights or
any of the rights of the Holders under the Collateral Documents and (b) receive
any and all amounts payable from the Collateral in respect of the obligations of
the Company and the Guarantors hereunder. Subject to the provisions of the
Collateral Documents and the Intercreditor Acknowledgment, the Trustee shall
have the power to institute and to maintain such suits and proceedings as it may
deem expedient to prevent any impairment of the Collateral by any acts that may
be unlawful or in violation of the Collateral Documents or this Indenture, and
such suits and proceedings as the Trustee may deem expedient to preserve or
protect its interest and the interests of the Holders in the Collateral
