                                   ARTICLE 1.

                                   DEFINITIONS

               Section 1.1. Definitions. The terms defined in this Section 1.1

hereto shall have the respective meanings specified in this Section 1.1. All
other terms used in this Indenture that are defined in the Trust Indenture Act
or which are by reference therein defined in the Securities Act (except as

in said Securities Act as in force at the date of the execution of this
Indenture. The words "herein", "hereof", "hereunder", and words of similar

import refer to this Indenture as a whole and not to any particular Article,
Section or other Subdivision. The terms defined in this Article include the
plural as well as the singular.

               "Affiliate" of any specified Person means any other Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with such specified Person. For the purposes of this definition,
"control", when used with respect to any specified Person means the power to
direct or cause the direction of the management and policies of such Person,
directly or indirectly, whether through the ownership of voting securities, by
contract or otherwise, and the terms "controlling" and "controlled" have
meanings correlative to the foregoing.

               "Board of Directors" means the Board of Directors of the Company
or a committee of such Board duly authorized to act for it hereunder.

               "Business Day" means each Monday, Tuesday, Wednesday, Thursday
and Friday which is not a day on which the banking institutions in New York City
or the city in which the Corporate Trust Office is located are authorized or
obligated by law or executive order to close or be closed.

               "Closing Price" has the meaning specified in Section 15.5(h)(1).

               "Commission" means the Securities and Exchange Commission, as
from time to time constituted, created under the Exchange Act, or, if at any
time after the execution of this Indenture such Commission is not existing and

               "Common Stock" means any stock of any class of the Company which

reclassifications thereof and which have no preference in respect of dividends
or of amounts payable in the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Company and which are not subject to redemption
by the Company; provided, however, that if at any time there shall be more than
one such resulting class, the shares of each such class then so issuable shall
be substantially in the proportion which the total number of shares of such
class resulting from all such reclassifications bears to the total number of
shares of all such classes resulting from all such reclassifications.

               "Company" means the corporation named as the "Company" in the
first paragraph of this Indenture, and, subject to the provisions of Article

Company shall execute, and the Trustee shall authenticate and deliver, the Notes
which the Noteholder making the exchange is entitled to receive bearing
registration numbers not contemporaneously outstanding.

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

               All Notes presented or surrendered for registration of transfer
or for exchange, redemption or conversion shall (if so required by the Company
or the Note registrar) be duly endorsed, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company, and
the Notes shall be duly executed by the Noteholder thereof or his attorney duly
authorized in writing.

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

               Neither the Company nor the Trustee nor any Note registrar shall
be required to exchange or register a transfer of (a) any Notes for a period of
fifteen (15) days next preceding the mailing of a notice of redemption of Notes
to be redeemed, (b) any Notes or portions thereof



                                       11
<PAGE>   18
called for redemption pursuant to Section 3.2, (c) any Notes or portions thereof
surrendered for conversion pursuant to Article Fifteen or (d) any Notes or
portions thereof tendered for redemption (and not withdrawn) pursuant to Section
3.5.

               (b) So long as the Notes are eligible for book-entry
settlement with the Depositary, or unless otherwise required by law, all Notes
that, upon initial issuance are beneficially owned by QIBs or as a result of a
sale or transfer after initial issuance are beneficially owned by QIBs, will be
represented by one or more Notes in global form registered in the name of the
Depositary or the nominee of the Depositary (the "Global Note"), except as
otherwise specified below. The transfer and exchange of beneficial interests in
any such Global Note shall be effected through the Depositary in accordance with
this Indenture and the procedures of the Depositary therefor. The Trustee shall
make appropriate endorsements to reflect increases or decreases in the principal
amounts of any such Global Note as set forth on the face of the Note ("Principal
Amount") to reflect any such transfers. Except as provided below, beneficial
owners of a Global Note shall not be entitled to have certificates registered in
their names, will not receive or be entitled to receive physical delivery of
certificates in definitive form and will not be considered holders of such
Global Note.

               (c) So long as the Notes are eligible for book-entry
settlement with the Depositary, or unless otherwise required by law, upon any
transfer of a definitive Note to a QIB in accordance with Rule 144A, and upon
receipt of the definitive Note or Notes being so transferred, together with a
certification, substantially in the form on the reverse of the Note, from the
transferor that the transfer is being made in compliance with Rule 144A (or
other evidence satisfactory to the Trustee), the Trustee shall make an
endorsement on the Global Note to reflect an increase in the aggregate Principal
Amount of the Notes represented by such Global Note, and the Trustee shall
cancel such definitive Note or Notes in accordance with the standing
instructions and procedures of the Depositary, the aggregate Principal Amount of
the Notes represented by such Global Note to be increased accordingly; provided,
however, that no definitive Note, or portion thereof, in respect of which the
Company or an Affiliate of the Company held any beneficial interest shall be
included in such Global Note until such definitive Note is freely tradable in
accordance with Rule 144(k) under the Securities Act, provided further that the
Trustee shall issue Notes in definitive form upon any transfer of a beneficial
interest in the Global Note to the Company or any Affiliate of the Company.

               Upon any sale or transfer of a Note to an Institutional
Accredited Investor (other than pursuant to a registration statement that has
been declared effective under the Securities Act), such Institutional Accredited
Investor shall, prior to such sale or transfer, furnish to the Company and/or
the Trustee a signed letter containing representations and agreements relating
to restrictions on transfer substantially in the form set forth in Exhibit B to
this Indenture. Upon any transfer of a beneficial interest in the Global Note to
an Institutional Accredited Investor, the Trustee shall make an endorsement on
the Global Note to reflect a decrease in the aggregate Principal Amount of the
Notes represented by such Global Note, and the Company shall execute a
definitive Note or Notes in exchange therefor, and the Trustee, upon receipt of
such definitive Note or Notes and the written order of the Company, shall
authenticate and deliver such, definitive Note or Notes.

               Any Global Note may be endorsed with or have incorporated in the
text thereof such legends or recitals or changes not inconsistent with the
provisions of this Indenture as may be required by the Custodian, the Depositary
or by the National Association of Securities Dealers, Inc. in order for the
Notes to be tradeable on the Portal Market or as may be required for the Notes
to be tradeable on any other market developed for trading of securities pursuant
to Rule 144A or required to comply with any applicable law or any regulation
thereunder or with the rules and regulations of any securities exchange or
automated quotation system upon which the Notes may be listed or traded or to
conform with any usage with respect thereto, or to indicate any special
limitations or restrictions to which any particular Notes are subject.

               (d) Every Note that bears or is required under this Section
2.5(d) to bear the legend set forth in this Section 2.5(d) (together with any
Common Stock issued upon conversion of the Notes and required to bear the legend
set forth in Section 2.5(e), collectively, the "Restricted Securities") shall be
subject to the restrictions on transfer set forth in this Section 2.5(d)
(including those set forth in the legend set forth below) unless such
restrictions on transfer shall be waived by written consent of the Company, and
the holder of each such Restricted Security, by such Noteholder's acceptance
thereof, agrees to be bound by all such restrictions on transfer. As used in
Sections 2.5(d) and 2.5(e), the term "transfer" encompasses any sale, pledge,
loan, transfer or other disposition whatsoever of any Restricted Security.

               Until the expiration of the holding period applicable to sales
thereof under Rule 144(k) under the Securities Act (or any successor provision),
any certificate evidencing such Note (and all securities issued in exchange
therefor or substitution thereof, other than Common Stock, if any, issued upon
conversion thereof, which shall bear the legend set forth in Section 2.5(e), if
applicable) shall bear a legend in substantially the following form, unless such
Note has been sold pursuant to a registration statement that has been declared
effective under the Securities Act (and which continues to be effective at the
time of such transfer), or unless otherwise agreed by the Company in writing,
with written notice thereof to the Trustee:

        THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED
        STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
        STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD
        WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, UNITED
        STATES PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS
        ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A
        "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE
        SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS
        DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT)
        ("INSTITUTIONAL ACCREDITED INVESTOR"); (2) AGREES THAT IT WILL NOT,
        PRIOR TO EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE
        NOTE EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY
        SUCCESSOR PROVISION), RESELL OR OTHERWISE TRANSFER THE NOTE EVIDENCED
        HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH NOTE EXCEPT
        (A) TO GETTY IMAGES, INC. OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED
        INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES
        ACT, (C) TO AN



                                       13

        INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER,
        FURNISHES TO THE BANK OF NEW YORK, AS TRUSTEE (OR A SUCCESSOR TRUSTEE,
        AS APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
        AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE NOTE
        EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH
        TRUSTEE OR A SUCCESSOR TRUSTEE, AS APPLICABLE), (D) PURSUANT TO THE
        EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
        ACT (IF AVAILABLE) OR (E) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS
        BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO
        BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (3) PRIOR TO SUCH TRANSFER
        (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (2)(E) ABOVE), IT WILL FURNISH
        TO THE BANK OF NEW YORK, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS
        APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS
        THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS
        BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT
        SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (4)
        AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE NOTE EVIDENCED
        HEREBY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS
        LEGEND. IN CONNECTION WITH ANY TRANSFER OF THE NOTE EVIDENCED HEREBY
        PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE
        NOTE EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY
        SUCCESSOR PROVISION), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET
        FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND
        SUBMIT THIS CERTIFICATE TO THE BANK OF NEW YORK, AS TRUSTEE (OR A
        SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFEREE IS AN
        INSTITUTIONAL ACCREDITED INVESTOR OR IS A PURCHASER WHO IS NOT A UNITED
        STATES PERSON, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE
        BANK OF NEW YORK, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE),
        SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS SUCH TRUSTEE
        MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE
        PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
        REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE
        REMOVED UPON THE EARLIER OF THE TRANSFER OF THE NOTE EVIDENCED HEREBY
        PURSUANT TO CLAUSE (2)(E) ABOVE OR UPON ANY TRANSFER OF THE NOTE
        EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY
        SUCCESSOR PROVISION). AS USED HEREIN, THE TERMS "UNITED STATES" AND
        "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE
        SECURITIES ACT.

               Any Note (or security issued in exchange or substitution
therefor) as to which such restrictions on transfer shall have expired in
accordance with their terms or as to conditions for removal of the foregoing
legend set forth therein have been satisfied may, upon surrender of



                                       14
<PAGE>   21

such Note for exchange to the Note registrar in accordance with the provisions
of this Section 2.5, be exchanged for a new Note or Notes, of like tenor and
aggregate principal amount, which shall not bear the restrictive legend required
by this Section 2.5(d).

               Notwithstanding any other provisions of this Indenture (other
than the provisions set forth in the second paragraph of Section 2.5(c) and in
this Section 2.5(d)), a Global Note may not be transferred as a whole or in part
except 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.

               The Depositary shall be a clearing agency registered under the
Exchange Act. The Company initially appoints The Depository Trust Company to act
as Depositary with respect to the Notes in global form. Initially, the Global
Note shall be issued to the Depositary, registered in the name of Cede & Co., as
the nominee of the Depositary, and deposited with the Custodian for Cede & Co.

               If at any time the Depositary for a Global Note notifies the
Company that it is unwilling or unable to continue as Depositary for such Note,
the Company may appoint a successor Depositary with respect to such Note. If a
successor Depositary is not appointed by the Company within ninety (90) days
after the Company receives such notice, the Company will execute, and the
Trustee, upon receipt of an Officers' Certificate for the authentication and
delivery of Notes, will authenticate and deliver, Notes in certificated form, in
aggregate principal amount equal to the principal amount of such Global Note, in
exchange for such Global Note.

               If a Note in certificated form is issued in exchange for any
portion of a Global Note after the close of business at the office or agency
where such exchange occurs on any record date and before the opening of business
at such office or agency on the next succeeding interest payment date, interest
will not be payable on such interest payment date in respect of such
certificated Note, but will be payable on such interest payment date, subject to
the provisions of Section 2.3, only to the Person to whom interest in respect of
such portion of such Global Note is payable in accordance with the provisions of
this Indenture.

               Notes in certificated form issued in exchange for all or a part
of a Global Note pursuant to this Section 2.5 shall be registered in such names
and in such authorized denominations as the Depositary, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee. Upon execution and authentication, the Trustee shall deliver such Notes
in certificated form to the Persons in whose names such Notes in certificated
form are so registered.

               At such time as all interests in a Global Note have been
redeemed, converted, canceled, exchanged for Notes in certificated form, or
transferred to a transferee who receives Notes in certificated form thereof,
such Global Note shall, upon receipt thereof, be canceled by the Trustee in
accordance with standing procedures and instructions existing between the
Depositary and the Custodian. At any time prior to such cancellation, if any
interest in a Global Note is exchanged for Notes in certificated form, redeemed,
converted, repurchased or canceled, or transferred to a transferee who receives
Notes in certificated form therefor or any Note in



                                       15
<PAGE>   22

certificated form is exchanged or transferred for part of a Global Note, the
principal amount of such Global Note shall, in accordance with the standing
procedures and instructions existing between the Depositary and the Custodian,
be appropriately reduced or increased, as the case may be, and an endorsement
shall be made on such Global Note, by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase.

               (e) Until the expiration of the holding period applicable to
sales thereof under Rule 144(k) under the Securities Act (or any successor
provision), any stock certificate representing Common Stock issued upon
conversion of any Note shall bear a legend in substantially the following form,
unless such Common Stock has been sold pursuant to a registration statement that
has been declared effective under the Securities Act (and which continues to be
effective at the time of such transfer) or such Common Stock has been issued
upon conversion of Notes that have been transferred pursuant to a registration
statement that has been declared effective under the Securities Act, or unless
otherwise agreed by the Company in writing with written notice thereof to the
transfer agent:

        THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE
        UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
        OR ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR
        SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF,
        UNITED STATES PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. THE
        HOLDER HEREOF AGREES THAT UNTIL THE EXPIRATION OF THE HOLDING PERIOD
        APPLICABLE TO SALES OF THE SECURITY EVIDENCED HEREBY UNDER RULE 144(K)
        UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), (1) IT WILL NOT
        RESELL OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT
        (A) TO GETTY IMAGES, INC. OR TO ANY SUBSIDIARY THEREOF, (B) TO A
        "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE
        SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C) TO AN INSTITUTIONAL
        "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7)
        UNDER THE SECURITIES ACT) THAT PRIOR TO SUCH TRANSFER, FURNISHES TO THE
        BANK OF NEW YORK, AS TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT, AS
        APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
        AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE COMMON STOCK
        EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH
        TRANSFER AGENT OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), (D)
        PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER
        THE SECURITIES ACT (IF AVAILABLE), OR (E) PURSUANT TO A REGISTRATION
        STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
        (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (2)
        PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (1)(E)
        ABOVE), IT WILL FURNISH TO THE BANK OF NEW YORK, AS TRANSFER AGENT (OR
        SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL
        OPINIONS OR OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY




                                       16
<PAGE>   23

        REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
        EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
        REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT WILL DELIVER TO EACH
        PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER
        THAN A TRANSFER PURSUANT TO CLAUSE 1(E) ABOVE) A NOTICE SUBSTANTIALLY TO
        THE EFFECT OF THIS LEGEND. IF THE PROPOSED TRANSFEREE IS AN
        INSTITUTIONAL ACCREDITED INVESTOR OR IS A PURCHASER WHO IS NOT A UNITED
        STATES PERSON, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE
        BANK OF NEW YORK (OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH
        CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS IT MAY REASONABLY
        REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
        EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
        REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE
        EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY PURSUANT TO
        CLAUSE (1)(E) ABOVE OR UPON ANY TRANSFER OF THE COMMON STOCK EVIDENCED
        HEREBY AFTER THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF
        THE SECURITY EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT
        (OR ANY SUCCESSOR PROVISION). AS USED HEREIN, THE TERMS "UNITED STATES"
        AND "UNITED STATES PERSON" HAVE THE MEANING GIVEN TO THEM BY REGULATION
        S UNDER THE SECURITIES ACT.

               Any such Common Stock as to which such restrictions on transfer
shall have expired in accordance with their terms or as to which the conditions
for removal of the foregoing legend set forth therein have been satisfied may,
upon surrender of the certificates representing such shares of Common Stock for
exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like number of
shares of Common Stock, which shall not bear the restrictive legend required by
this Section 2.5(e).

               (f) Any Note or Common Stock issued upon the conversion or
exchange of a Note that, prior to the expiration of the holding period
applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), is purchased or owned by the Company or any Affiliate
thereof may not be resold by the Company or such Affiliate unless registered
under the Securities Act or resold pursuant to an exemption from the
registration requirements of the Securities Act in a transaction which results
in such Notes or Common Stock, as the case may be, no longer being "restricted
securities" (as defined under Rule 144).

               The Trustee shall have no additional obligation or duty to
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 Note (including any transfers between or among Depositary
participants or beneficial owners of interests in any Global Note), 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



                                       17
<PAGE>   24

examine the same to determine substantial compliance as to form with the express
requirements hereof.

        Section 2.6. Mutilated, Destroyed, Lost Or Stolen Notes. In case any
Note shall become mutilated or be destroyed, lost or stolen, the Company in its
discretion may execute, and upon its written request the Trustee or an
authenticating agent appointed by the Trustee shall authenticate and make
available for delivery, a new Note, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of
and in substitution for the Note so destroyed, lost or stolen. In every case the
applicant for a substituted Note shall furnish to the Company, to the Trustee
and, if applicable, to such authenticating agent such security or indemnity as
may be required by them to save each of them harmless for any loss, liability,
cost or expense caused by or connected with such substitution, and, in every
case of destruction, loss or theft, the applicant shall also furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent
evidence to their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof.

               Following receipt by the Trustee or such authenticating agent, as
the case may be, of satisfactory security or indemnity and evidence, as
described in the preceding paragraph, the Trustee or such authenticating agent
may authenticate any such substituted Note and make available for delivery such
Note. Upon the issuance of any substituted Note, the Company may require the
payment by the holder of a sum sufficient to cover any tax, assessment or other
governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. In case any Note which has matured or is about to
mature or has been called for redemption or has been tendered for redemption
(and not withdrawn) or is to be converted into Common Stock shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Note, pay or authorize the payment of or convert or authorize the
conversion of the same (without surrender thereof except in the case of a
mutilated Note), as the case may be, if the applicant for such payment or
conversion shall furnish to the Company, to the Trustee and, if applicable, to
such authenticating agent such security or indemnity as may be required by them
to save each of them harmless for any loss, liability, cost or expense caused by
or connected with such substitution, and, in every case of destruction, loss or
theft, the applicant shall also furnish to the Company, the Trustee and, if
applicable, any paying agent or conversion agent evidence to their satisfaction
of the destruction, loss or theft of such Note and of the ownership thereof.

               Every substitute Note issued pursuant to the provisions of this
Section 2.6 by virtue of the fact that any Note is destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not the destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other
Notes duly issued hereunder. To the extent permitted by law, all Notes shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment or conversion of mutilated,
destroyed, lost or stolen Notes and shall preclude any and all other rights or
remedies notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the replacement or payment or conversion of negotiable
instruments or other securities without their surrender.

        Section 2.7. Temporary Notes. Pending the preparation of Notes in
certificated form, the Company may execute and the Trustee or an authenticating
agent appointed by the Trustee shall, upon the written request of the Company,
authenticate and deliver temporary Notes (printed or lithographed). Temporary
Notes shall be issuable in any authorized denomination, and substantially in the
form of the Notes in certificated form, but with such omissions, insertions and
variations as may be appropriate for temporary Notes, all as may be determined
by the Company. Every such temporary Note shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as
the Notes in certificated form. Without unreasonable delay the Company will
execute and deliver to the Trustee or such authenticating agent Notes in
certificated form (other than in the case of Notes in global form) and thereupon
any or all temporary Notes (other than any such Global Note) may be surrendered
in exchange therefor, at each office or agency maintained by the Company
pursuant to Section 5.2 and the Trustee or such authenticating agent shall
authenticate and make available for delivery in exchange for such temporary
Notes an equal aggregate principal amount of Notes in certificated form. Such
exchange shall be made by the Company at its own expense and without any charge
therefor. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits and subject to the same limitations under this
Indenture as Notes in certificated form authenticated and delivered hereunder.

        Section 2.8. Cancellation Of Notes Paid, Etc. All Notes surrendered for
the purpose of payment, redemption, conversion, exchange or registration of
transfer shall, if surrendered to the Company or any paying agent or any Note
registrar or any conversion agent, be surrendered to the Trustee and promptly
canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by
it, and no Notes shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Indenture. The Trustee shall dispose of such
canceled Notes in accordance with its customary procedures. If the Company shall
acquire any of the Notes, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Notes unless and until the
same are delivered to the Trustee for cancellation.

        Section 2.9. CUSIP Numbers. The Company in issuing the Notes may use
"CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Noteholders;
provided, however, that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Notes or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Notes, and any such redemption
shall not be affected by any defect in or omission of such numbers. The Company
will promptly notify the Trustee of any change in the "CUSIP" numbers.

                               REDEMPTION OF NOTES

               (a) Except as otherwise provided in Section 3.5, the Notes may
not be redeemed by the Company, in whole or in part, at any time prior to March

               (b) Optional Redemption By The Company. At any time on or
after March 20, 2003, and prior to maturity, the Notes may be redeemed at the
option of the Company, in whole or in part, upon notice as set forth in Section

principal amount), together in each case with accrued and unpaid interest, if
any (including Liquidated Damages, if any) to, but excluding, the date fixed for
redemption:

</TABLE>

and 100% on March 15, 2007; provided, however, that if the date fixed for
redemption is on a March 15 or September 15, then the interest payable on such
date shall be paid to the holder of record on the preceding March 1 or September
1, respectively.

        Section 3.2. Notice Of Redemptions; Selection Of Notes. In case the
Company shall desire to exercise the right to redeem all or, as the case may be,
any part of the Notes pursuant to Section 3.1, it shall fix a date for
redemption and it or, at its written request received by the Trustee not fewer
than forty-five (45) days prior (or such shorter period of time as may be
acceptable to the Trustee) to the date fixed for redemption, the Trustee in the
name of and at the expense of the Company, shall mail or cause to be mailed a
notice of such redemption not fewer than thirty (30) nor more than sixty (60)
days prior to the date fixed for redemption to the holders of Notes so to be
redeemed as a whole or in part at their last addresses as the same appear on the
Note register; provided, however, that if the Company shall give such notice, it
shall also give written notice, and written notice of the Notes to be redeemed,
to the Trustee. Such mailing shall be by first class mail. The notice if 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 to the holder of any Note
designated for redemption as a whole or in part shall not affect the validity of
the proceedings for the redemption of any other Note. Concurrently with the
mailing of any such notice of redemption, the Company shall issue a press
release announcing such redemption, the form and content of which press release
shall be determined by the Company in its sole discretion. The failure to issue
any such press release or any defect therein shall not affect the validity of
the redemption notice or any of the proceedings for the redemption of any Note
called for redemption.

               Each such notice of redemption shall specify the aggregate
principal amount of Notes to be redeemed, the CUSIP number or numbers of the
Notes being redeemed, the date fixed for redemption (which shall be a Business
Day), the redemption price at which Notes are to be redeemed, the place or
places of payment, that payment will be made upon presentation and surrender of
such Notes, that interest accrued to the date fixed for redemption will be paid
as specified in said notice, and that on and after said date interest thereon or
on the portion thereof to be redeemed will cease to accrue. Such notice shall
also state the current Conversion Price and the date on which the right to
convert such Notes or portions thereof into Common Stock



                                       20
<PAGE>   27

will expire. If fewer than all the Notes are to be redeemed, the notice of
redemption shall identify the Notes to be redeemed (including CUSIP numbers, if
any). In case any Note is to be redeemed in part only, the notice of redemption
shall state the portion of the principal amount thereof to be redeemed and shall
state that, on and after the date fixed for redemption, upon surrender of such
Note, a new Note or Notes in principal amount equal to the unredeemed portion
thereof will be issued.

               On or prior to the redemption date specified in the notice of
redemption given as provided in this Section 3.2, the Company will deposit with
the Trustee or with one or more paying agents (or, if the Company is acting as
its own paying agent, set aside, segregate and hold in trust as provided in
Section 5.4) an amount of money in immediately available funds sufficient to
redeem on the redemption date all the Notes (or portions thereof) so called for
redemption (other than those theretofore surrendered for conversion into Common
Stock) at the appropriate redemption price, together with accrued interest to,
but excluding, the date fixed for redemption; provided, however, that if such
payment is made on the redemption date it must be received by the Trustee or
paying agent, as the case may be, by 10:00 a.m., New York City time, on such
date. The Company shall be entitled to retain any interest, yield or gain on
amounts deposited with the Trustee or any paying agent pursuant to this Section
3.2 in excess of amounts required hereunder to pay the redemption price together
with accrued interest to, but excluding, the date fixed for redemption. If any
Note called for redemption is converted pursuant hereto prior to such
redemption, any money deposited with the Trustee or any paying agent or so
segregated and held in trust for the redemption of such Note shall be paid to
the Company upon its written request, or, if then held by the Company, shall be
discharged from such trust. Whenever any Notes are to be redeemed, the Company
will give the Trustee written notice in the form of an Officers' Certificate not
fewer than forty-five (45) days (or such shorter period of time as may be
acceptable to the Trustee) prior to the redemption date as to the aggregate
principal amount of Notes to be redeemed.

               If less than all of the outstanding Notes are to be redeemed, the
Trustee shall select the Notes or portions thereof of the Global Note or the
Notes in certificated form to be redeemed (in principal amounts of $1,000 or
integral multiples thereof) by lot, on a pro rata basis or by another method the
Trustee deems fair and appropriate. If any Note selected for partial redemption
is submitted for conversion in part after such selection, the portion of such
Note submitted for conversion shall be deemed (so far as may be) to be the
portion to be selected for redemption. The Notes (or portions thereof) so
selected shall be deemed duly selected for redemption for all purposes hereof,
notwithstanding that any such Note is submitted for conversion in part before
the mailing of the notice of redemption.

               Upon any redemption of less than all of the outstanding Notes,
the Company and the Trustee may (but need not), solely for purposes of
determining the pro rata allocation among such Notes as are unconverted and
outstanding at the time of redemption, treat as outstanding any Notes
surrendered for conversion during the period of fifteen (15) days next preceding
the mailing of a notice of redemption and may (but need not) treat as
outstanding any Note authenticated and delivered during such period in exchange
for the unconverted portion of any Note converted in part during such period.

        Section 3.3. Payment Of Notes Called For Redemption. If notice of
redemption has been given as above provided, the Notes or portion of Notes with
respect to which such notice has been given shall, unless converted into Common
Stock pursuant to the terms hereof, become due and payable on the date fixed for
redemption and at the place or places stated in such notice at the applicable
redemption price, together with interest accrued to (but excluding) the date
fixed for redemption, and on and after said date (unless the Company shall
default in the payment of such Notes at the redemption price, together with
interest accrued to said date) interest on the Notes or portion of Notes so
called for redemption shall cease to accrue and, after the close of business on
the Business Day next preceding the date fixed for redemption, such Notes shall
cease to be convertible into Common Stock and, except as provided in Sections
8.5 and 13.4, to be entitled to any benefit or security under this Indenture,
and the holders thereof shall have no right in respect of such Notes except the
right to receive the redemption price thereof and unpaid interest to (but
excluding) the date fixed for redemption. On presentation and surrender of such
Notes at a place of payment in said notice specified, the said Notes or the
specified portions thereof shall be paid and redeemed by the Company at the
applicable redemption price, together with interest accrued thereon to (but
excluding) the date fixed for redemption; provided, however, that if the
applicable redemption date is an interest payment date, the semi-annual payment
of interest becoming due on such date shall be payable to the holders of such
Notes registered as such on the relevant record date instead of the holders
surrendering such Notes for redemption on such date.

               Upon presentation of any Note redeemed in part only, the Company
shall execute and the Trustee shall authenticate and make available for delivery
to the holder thereof, at the expense of the Company, a new Note or Notes, of
authorized denominations, in principal amount equal to the unredeemed portion of
the Notes so presented.

               Notwithstanding the foregoing, the Trustee shall not redeem any
Notes or mail any notice of redemption during the continuance of a default in
payment of interest or premium, if any, on the Notes. If any Note called for
redemption shall not be so paid upon surrender thereof for redemption, the
principal and premium, if any, shall, until paid or duly provided for, bear
interest from the date fixed for redemption at the rate borne by the Note and
such Note shall remain convertible into Common Stock until the principal and
premium, if any, and interest shall have been paid or duly provided for.

        Section 3.4. Conversion Arrangement On Call For Redemption. In
connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes by an agreement with one or more investment
bankers or other purchasers to purchase such Notes by paying to the Trustee in
trust for the Noteholders, on or before the date fixed for redemption, an amount
not less than the applicable redemption price, together with interest accrued to
(but excluding) the date fixed for redemption, of such Notes. Notwithstanding
anything to the contrary contained in this Article Three, the obligation of the
Company to pay the redemption price of such Notes, together with interest
accrued to (but excluding) the date fixed for redemption, shall be deemed to be
satisfied and discharged to the extent such amount is so paid by such
purchasers. If such an agreement is entered into, a copy of which will be filed
with the Trustee prior to the date fixed for redemption, any Notes not duly
surrendered for conversion by the holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such holders and (notwithstanding anything



                                       22
<PAGE>   29

to the contrary contained in Article Fifteen) surrendered by such purchasers for
conversion, all as of immediately prior to the close of business on the date
fixed for redemption (and the right to convert any such Notes shall be extended
through such time), subject to payment of the above amount as aforesaid. At the
direction of the Company, the Trustee shall hold and dispose of any such amount
paid to it in the same manner as it would monies deposited with it by the
Company for the redemption of Notes. Without the Trustee's prior written
consent, no arrangement between the Company and such purchasers for the purchase
and conversion of any Notes shall increase or otherwise affect any of the
powers, duties, responsibilities or obligations of the Trustee as set forth in
this Indenture.

        Section 3.5. Redemption At Option Of Holders.

               (a) If there shall occur a Fundamental Change at any time prior
to maturity of the Notes, then each Noteholder shall have the right, at such
holder's option, to require the Company to redeem all of such holder's Notes, or
any portion thereof that is an integral multiple of $1,000 principal amount, on
the date (the "Repurchase Date") that is thirty (30) days after the date of the
Company Notice (as defined in Section 3.5(b) below) of such Fundamental Change
(or, if such 30th day is not a Business Day, the next succeeding Business Day)
at a redemption price equal to 100% of the principal amount thereof, together
with accrued interest to (but excluding) the Repurchase Date; provided, however,
that, if such Repurchase Date is a March 15 or September 15, then the interest
payable on such date shall be paid to the holders of record of the Notes on the
next preceding March 1 or September 1, respectively.

               Upon presentation of any Note redeemed in part only, the Company
shall execute and, upon the Company's written direction to the Trustee, the
Trustee shall authenticate and deliver to the holder thereof, at the expense of
the Company, a new Note or Notes, of authorized denominations, in principal
amount equal to the unredeemed portion of the Notes so presented.

               (b) On or before the tenth day after the occurrence of a
Fundamental Change, the Company or at its written request (which must be
received by the Trustee at least five (5) Business Days prior to the date the
Trustee is requested to give notice as described below, unless the Trustee shall
agree in writing to a shorter period), the Trustee, in the name of and at the
expense of the Company, shall mail or cause to be mailed to all holders of
record on the date of the Fundamental Change a notice (the "Company Notice") of
the occurrence of such Fundamental Change and of the redemption right at the
option of the holders arising as a result thereof. Such notice shall be mailed
in the manner and with the effect set forth in the first paragraph of Section
3.2 (without regard for the time limits set forth therein). If the Company shall
give such notice, the Company shall also deliver a copy of the Company Notice to
the Trustee at such time as it is mailed to Noteholders. Concurrently with the
mailing of any Company Notice, the Company shall issue a press release
announcing such Fundamental Change referred to in the Company Notice, the form
and content of which press release shall be determined by the Company in its
sole discretion. The failure to issue any such press release or any defect
therein shall not affect the validity of the Company Notice or any proceedings
for the redemption of any Note which any Noteholder may elect to have the
Company redeem as provided in this Section 3.5.




                                       23
<PAGE>   30

               Each Company Notice shall specify the circumstances constituting
the Fundamental Change, the Repurchase Date, the price at which the Company
shall be obligated to redeem Notes, that the holder must exercise the redemption
right on or prior to the close of business on the Repurchase Date (the
"Fundamental Change Expiration Time"), that the holder shall have the right to
withdraw any Notes surrendered prior to the Fundamental Change Expiration Time,
a description of the procedure which a Noteholder must follow to exercise such
redemption right and to withdraw any surrendered Notes, the place or places
where the holder is to surrender such holder's Notes, the amount of interest
accrued on each Note to the Repurchase Date and the "CUSIP" number or numbers of
the Notes (if then generally in use).

               No failure of the Company to give the foregoing notices and no
defect therein shall limit the Noteholders' redemption rights or affect the
validity of the proceedings for the redemption of the Notes pursuant to this
Section 3.5.

               (c) For a Note to be so redeemed at the option of the holder, the
Company must receive at the office or agency of the Company maintained for that
purpose or, at the option of such holder, the Corporate Trust Office, such Note
with the form entitled "Option to Elect Repayment Upon A Fundamental Change" on
the reverse thereof duly completed, together with such Notes duly endorsed for
transfer, on or before the Fundamental Change Expiration Time. All questions as
to the validity, eligibility (including time of receipt) and acceptance of any
Note for repayment shall be determined by the Company, whose determination shall
be final and binding absent manifest error.

               (d) On or prior to the Repurchase Date, the Company will deposit
with the Trustee or with one or more paying agents (or, if the Company is acting
as its own paying agent, set aside, segregate and hold in trust as provided in
Section 5.4) an amount of money sufficient to redeem on the Repurchase Date all
the Notes to be redeemed on such date at the appropriate redemption price,
together with accrued interest to (but excluding) the Repurchase Date; provided,
however, that if such payment is made on the Repurchase Date it must be received
by the Trustee or paying agent, as the case may be, by 10:00 a.m., New York City
time, on such date. Payment for Notes surrendered for redemption (and not
withdrawn) prior to the Fundamental Change Expiration Time will be made promptly
(but in no event more than five (5) Business Days) following the Repurchase Date
by mailing checks for the amount payable to the holders of such Notes entitled
thereto as they shall appear on the registry books of the Company.

               (e) In the case of a reclassification, change, consolidation,
merger, combination, sale or conveyance to which Section 15.6 applies, in which
the Common Stock of the Company is changed or exchanged as a result into the
right to receive stock, securities or other property or assets (including cash),
which includes shares of Common Stock of the Company or shares of common stock
of another Person that are, or upon issuance will be, traded on a United States
national securities exchange or approved for trading on an established automated
over-the-counter trading market in the United States and such shares constitute
at the time such change or exchange becomes effective in excess of 50% of the
aggregate fair market value of such stock, securities or other property or
assets (including cash) (as determined by the Company, which determination shall
be conclusive and binding), then the Person formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture (accompanied
by an Opinion of



                                       24
<PAGE>   31

Counsel that such supplemental indenture complies with the Trust Indenture Act
as in force at the date of execution of such supplemental indenture) modifying
the provisions of this Indenture relating to the right of holders of the Notes
to cause the Company to repurchase the Notes following a Fundamental Change,
including without limitation the applicable provisions of this Section 3.5 and
the definitions of Common Stock and Fundamental Change, as appropriate, as
determined in good faith by the Company (which determination shall be conclusive
and binding), to make such provisions apply to such other Person if different
from the Company and the common stock issued by such Person (in lieu of the
Company and the Common Stock of the Company).

               (f) The Company will comply with the provisions of Rule 13e-4 and
any other tender offer rules under the Exchange Act to the extent then
applicable in connection with the redemption rights of the holders of Notes in
the event of a Fundamental Change.

                                   ARTICLE 4.

                             SUBORDINATION OF NOTES

        Section 4.1. Agreement Of Subordination. The Company covenants and
agrees, and each holder of Notes issued hereunder by its acceptance thereof
likewise covenants and agrees, that all Notes shall be issued subject to the
provisions of this Article Four, and each Person holding any Note, whether upon
original issue or upon registration of transfer, assignment or exchange thereof,
accepts and agrees to be bound by such provisions.

               The payment of the principal of, premium, if any, and interest
(including Liquidated Damages, if any) on all Notes (including, but not limited
to, the redemption price with respect to the Notes called for redemption in
accordance with Section 3.2 or submitted for redemption in accordance with
Section 3.5, as the case may be, as provided in this Indenture) issued hereunder
shall, to the extent and in the manner hereinafter set forth, be subordinated
and subject in right of payment to the prior payment in full of all Senior
Indebtedness, whether outstanding at the date of this Indenture or thereafter
incurred.

               No provision of this Article Four shall prevent the occurrence of
any default or Event of Default hereunder.

        Section 4.2. Payments To Noteholders. No payment shall be made with
respect to the principal of, premium, if any, or interest (including Liquidated
Damages, if any) on the Notes (including, but not limited to, the redemption
price with respect to the Notes to be called for redemption in accordance with
Section 3.2 or submitted for redemption in accordance with Section 3.5, as the
case may be, as provided in this Indenture), except payments and distributions
made by the Trustee as permitted by the first or second paragraph of Section
4.5, if:

               (i) a default in the payment of principal, premium, if any,
interest, rent or other obligations in respect of Designated Senior Indebtedness
occurs and is continuing (or, in the case of Designated Senior Indebtedness for
which there is a period of grace, in the event of such a default that continues
beyond the period of grace, if any, specified in the instrument or



                                       25
<PAGE>   32

lease evidencing such Designated Senior Indebtedness) (a "Payment Default"),
unless and until such Payment Default shall have been cured or waived or shall
have ceased to exist; or

               (ii) a default, other than a Payment Default, on any Designated
Senior Indebtedness occurs and is continuing that then permits holders of such
Designated Senior Indebtedness to accelerate its maturity (or in the case of any
lease, a default occurs and is continuing that permits the lessor to either
terminate the lease or require the Company to make an irrevocable offer to
terminate the lease following an event of default thereunder) and the Trustee
receives a notice of the default (a "Payment Blockage Notice") from a holder of
Designated Senior Indebtedness, a Representative of Designated Senior
Indebtedness or the Company (a "Non-Payment Default").

               If the Trustee receives any Payment Blockage Notice pursuant to
clause (ii) above, no subsequent Payment Blockage Notice shall be effective for
purposes of this Section 4.2 unless and until at least 365 days shall have
elapsed since the initial effectiveness of the immediately prior Payment
Blockage Notice. No Non-Payment Default that existed or was continuing on the
date of delivery of any Payment Blockage Notice to the Trustee shall be, or be
made, the basis for a subsequent Payment Blockage Notice.

               The Company may and shall resume payments on and distributions in
respect of the Notes upon the earlier of:

                      (1) the date upon which any such Payment Default is cured
or waived or ceases to exist, or

                      (2) in the case of a Non-Payment Default, the earlier of
(a) the date upon which such default is cured or waived or ceases to exist or
(b) 179 days after the applicable Payment Blockage Notice is received by the
Trustee if the maturity of such Designated Senior Indebtedness has not been
accelerated (or in the case of any lease, 179 days after notice is received if
the Company has not received notice that the lessor under such lease has
exercised its right to terminate the lease or require the Company to make an
irrevocable offer to terminate the lease following an event of default
thereunder), unless this Article Four otherwise prohibits the payment or
distribution at the time of such payment or distribution.

               Upon any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding up or liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness shall first be paid in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness (and satisfactory to the
holders of Senior Indebtedness in the case such Senior Indebtedness includes
Designated Senior Indebtedness), or payment thereof in accordance with its terms
provided for in cash or other payment satisfactory to the holders of such Senior
Indebtedness (and satisfactory to the holders of Senior Indebtedness in the case
such Senior Indebtedness includes Designated Senior Indebtedness) before any
payment is made on account of the principal of, premium, if any, or interest
(including Liquidated Damages, if any) on the Notes (except payments made
pursuant to Article Thirteen from monies deposited with the Trustee pursuant
thereto prior to commencement of proceedings for such dissolution,



                                       26
<PAGE>   33

winding up, liquidation or reorganization), and upon any such dissolution or
winding up or liquidation or reorganization of the Company or bankruptcy,
insolvency, receivership or other similar proceeding, any payment by the
Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the holders of the Notes or
the Trustee would be entitled, except for the provisions of this Article Four,
shall (except as aforesaid) be paid by the Company or by any receiver, trustee
in bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the holders of the Notes or by the Trustee under this
Indenture if received by them or it, directly to the holders of Senior
Indebtedness (pro rata to such holders on the basis of the respective amounts of
Senior Indebtedness held by such holders, or as otherwise required by law or a
court order) or their Representative or Representatives, as their respective
interests may appear, to the extent necessary to pay all Senior Indebtedness in
full, in cash or other payment satisfactory to the holders of such Senior
Indebtedness (and satisfactory to the holders of Senior Indebtedness in the case
such Senior Indebtedness includes Designated Senior Indebtedness), after giving
effect to any concurrent payment or distribution to or for the holders of Senior
Indebtedness, before any payment or distribution is made to the holders of the
Notes or to the Trustee.

               For purposes of this Article Four, the words, "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Four with
respect to the Notes to the payment of all Senior Indebtedness which may at the
time be outstanding, provided that (i) the Senior Indebtedness is assumed by the
new corporation, if any, resulting from any reorganization or readjustment, and
(ii) the rights of the holders of Senior Indebtedness (other than leases which
are not assumed by the Company or the new corporation, as the case may be) are
not, without the consent of such holders, altered by such reorganization as the
case may be) are not, without the consent of such holders, altered by such
reorganization or readjustment. The consolidation of the Company with, or the
merger of the Company into, another corporation or the liquidation or
dissolution of the Company following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another Person upon the
terms and conditions provided for in Article Twelve shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 4.2 if such other Person shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions stated in Article Twelve.

               In the event of the acceleration of the Notes because of an Event
of Default, no payment or distribution shall be made to the Trustee or any
holder of Notes in respect of the principal of, premium, if any, or interest
(including Liquidated Damages, if any) on the Notes (including, but not limited
to, the redemption price with respect to the Notes called for redemption in
accordance with Section 3.2 or submitted for redemption in accordance with
Section 3.5, as the case may be, as provided in this Indenture), except payments
and distributions made by the Trustee as permitted by the first or second
paragraph of Section 4.5, until all Senior Indebtedness has been paid in full in
cash or other payment satisfactory to the holders of Senior Indebtedness (and
satisfactory to the holders of Designated Senior Indebtedness in the case such
Senior Indebtedness includes Designated Senior Indebtedness) or such
acceleration is rescinded in accordance with the terms of this Indenture. If
payment of the Notes is accelerated because of

an Event of Default, the Company or the Trustee shall promptly notify holders of
Senior Indebtedness (including the agent under the Credit Agreement) of the
acceleration.

               In the event that, notwithstanding the foregoing provisions, any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (including, without limitation, by way
of setoff or otherwise), prohibited by the foregoing provisions in this Section
4.2, shall be received by the Trustee or the holders of the Notes before all
Senior Indebtedness is paid in full in cash or other payment satisfactory to the
holders of such Senior Indebtedness (and satisfactory to the holders of Senior
Indebtedness in the case such Senior Indebtedness includes Designated Senior
Indebtedness), or provision is made for such payment thereof in accordance with
its terms in cash or other payment satisfactory to the holders of such Senior
Indebtedness (and satisfactory to the holders of Senior Indebtedness in the case
such Senior Indebtedness includes Designated Senior Indebtedness), such payment
or distribution shall be held in trust for the benefit of and shall be paid over
or delivered to the holders of Senior Indebtedness or their Representative or
Representatives, as their respective interests may appear, as calculated by the
Company, for application to the payment of any Senior Indebtedness remaining
unpaid to the extent necessary to pay all Senior Indebtedness in full in cash or
other payment satisfactory to the holders of such Senior Indebtedness (and
satisfactory to the holders of Senior Indebtedness in the case such Senior
Indebtedness includes Designated Senior Indebtedness), after giving effect to
any concurrent payment or distribution to or for the holders of such Senior
Indebtedness.

               Nothing in this Section 4.2 shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 8.6. This Section 4.2 shall be
subject to the further provisions of Section 4.5.

        Section 4.3. Subrogation Of Notes. Subject to the payment in full of all
Senior Indebtedness, the rights of the holders of the Notes shall be subrogated
to the extent of the payments or distributions made to the holders of such
Senior Indebtedness pursuant to the provisions of this Article Four (equally and
ratably with the holders of all indebtedness of the Company which by its express
terms is subordinated to other indebtedness of the Company to substantially the
same extent as the Notes are subordinated and is entitled to like rights of
subrogation) to the rights of the holders of Senior Indebtedness to receive
payments or distributions of cash, property or securities of the Company
applicable to the Senior Indebtedness until the principal, premium, if any, and
interest (including Liquidated Damages, if any) on the Notes shall be paid in
full, and, for the purposes of such subrogation, no payments or distributions to
the holders of the Senior Indebtedness of any cash, property or securities to
which the holders of the Notes or the Trustee would be entitled except for the
provisions of this Article Four, and no payment pursuant to the provisions of
this Article Four, to or for the benefit of the holders of Senior Indebtedness
by holders of the Notes or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness, and the holders of the
Notes, be deemed to be a payment by the Company to or on account of the Senior
Indebtedness, and no payments or distributions of cash, property or securities
to or for the benefit of the holders of the Notes pursuant to the subrogation
provisions of this Article Four, which would otherwise have been paid to the
holders of Senior Indebtedness, shall be deemed to be a payment by the Company
to or for the account of the Notes. It is understood that the provisions of this
Article



                                       28
<PAGE>   35

Four are intended solely for the purposes of defining the relative
rights of the holders of the Notes, on the one hand, and the holders of the
Senior Indebtedness, on the other hand.

               Nothing contained in this Article Four or elsewhere in this
Indenture or in the Notes is intended to or shall impair, as among the Company,
its creditors other than the holders of Senior Indebtedness, and the holders of
the Notes, the obligation of the Company, which is absolute and unconditional,
to pay to the holders of the Notes the principal of, premium, if any, and
interest (including Liquidated Damages, if any) on the Notes as and when the
same shall become due and payable in accordance with their terms, or is intended
to or shall affect the relative rights of the holders of the Notes and creditors
of the Company other than the holders of the Senior Indebtedness, nor shall
anything herein or therein prevent the Trustee or the holder of any Note from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article Four of the
holders of Senior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy.

               Upon any payment or distribution of assets of the Company
referred to in this Article Four, the Trustee, subject to the provisions of
Section 8.1, and the holders of the Notes shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which such
bankruptcy, dissolution, winding up, liquidation or reorganization proceedings
are pending, or a certificate of the receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
delivered to the Trustee or to the holders of the Notes, for the purpose of
ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, the
amount thereof or payable thereon and all other facts pertinent thereto or to
this Article Four.

        Section 4.4. Authorization To Effect Subordination. Each holder of a
Note by the holder's acceptance thereof authorizes and directs the Trustee on
the holder's behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article Four and appoints the
Trustee to act as the holder's attorney-in-fact for any and all such purposes.
If the Trustee does not file a proper proof of claim or proof of debt in the
form required in any proceeding referred to in the third paragraph of Section
7.2 hereof at least thirty (30) days before the expiration of the time to file
such claim, the holders of any Senior Indebtedness or their Representatives are
hereby authorized to file an appropriate claim for and on behalf of the holders
of the Notes.

        Section 4.5. Notice To Trustee. The Company shall give prompt written
notice in the form of an Officers' Certificate to a Responsible Officer of the
Trustee and to any paying agent of any fact known to the Company that would
prohibit the making of any payment of monies to or by the Trustee or any paying
agent in respect of the Notes pursuant to the provisions of this Article Four.
Notwithstanding the provisions of this Article Four or any other provision of
this Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts that would prohibit the making of any payment of monies to or by
the Trustee in respect of the Notes pursuant to the provisions of this Article
Four, unless and until a Responsible Officer of the Trustee shall have received
written notice thereof at the Corporate Trust Office from the Company (in the
form of an Officers' Certificate) or a Representative or a holder or holders of
Senior Indebtedness, and before the receipt of any such written notice, the
Trustee, subject to the



                                       29
<PAGE>   36

provisions of Section 8.1, shall be entitled in all respects to assume that no
such facts exist; provided, however, that if on a date not less than one
Business Day prior to the date upon which by the terms hereof any such monies
may become payable for any purpose (including, without limitation, the payment
of the principal of, or premium, if any, or interest (including Liquidated
Damages, if any) on any Note) the Trustee shall not have received, with respect
to such monies, the notice provided for in this Section 4.5, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to apply monies received to the purpose for which they were
received, and shall not be affected by any notice to the contrary that may be
received by it on or after such prior date.

               Notwithstanding anything in this Article Four to the contrary,
nothing shall prevent any payment by the Trustee to the Noteholders of monies
deposited with it pursuant to Section 13.1, if a Responsible Officer of the
Trustee shall not have received written notice at the Corporate Trust Office on
or before one Business Day prior to the date such payment is due that such
payment is not permitted under Section 4.1 or 4.2.

               The Trustee, subject to the provisions of Section 8.1, shall be
entitled to rely on the delivery to it of a written notice by a Representative
or a person representing himself to be a holder of Senior Indebtedness (or a
trustee on behalf of such holder) to establish that such notice has been given
by a Representative or a holder of Senior Indebtedness or a trustee on behalf of
any such holder or holders. The Trustee shall not be required to make any
payment or distribution to or on behalf of a holder of Senior Indebtedness
pursuant to this Article Four unless it has received satisfactory evidence as to
the amount of Senior Indebtedness held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such Person under this Article Four.

        Section 4.6. Trustee's Relation To Senior Indebtedness. The Trustee, in
its individual capacity, shall be entitled to all the rights set forth in this
Article Four in respect of any Senior Indebtedness at any time held by it, to
the same extent as any other holder of Senior Indebtedness, and nothing in
Section 8.13 or elsewhere in this Indenture shall deprive the Trustee of any of
its rights as such holder.

               With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Four, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and, subject to the
provisions of Section 8.1, the Trustee shall not be liable to any holder of
Senior Indebtedness (i) for any failure to make any payments or distributions to
such holder or (ii) if it shall pay over or deliver to holders of Notes, the
Company or any other Person money in compliance with this Article Four.

        Section 4.7. No Impairment Of Subordination. No right of any present or
future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof



                                       30

which any such holder may have or otherwise be charged with. Senior Indebtedness
may be created, renewed or extended and holders of Senior Indebtedness may
exercise any rights under any instrument creating or evidencing such Senior
Indebtedness, including, without limitation, any waiver of default thereunder,
without any notice to or consent from the holders of the Notes or the Trustee.
No compromise, alteration, amendment, modification, extension, renewal or other
change of, or waiver, consent or other action in respect of, any liability or
obligation under or in respect of the Senior Indebtedness or any terms or
conditions of any instrument creating or evidencing such Senior Indebtedness
shall in any way alter or affect
