the Common Stock is traded or, if the Common Stock is not listed on a United
States national or regional securities exchange, as reported by the Nasdaq

by the Company; provided 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 to 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.

and Conversion Agent in connection with the Securities.

written request of the Trustee, forthwith pay to the Trustee all sums so held in

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

SECTION 2.5. SECURITYHOLDER 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
Securityholders. If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least five Business Days prior to each semi-annual 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 Securityholders.

                                       12

SECTION 2.6. TRANSFER AND EXCHANGE.

         (a) The Securities shall be issued in registered form and shall be
transferable only upon surrender for registration of transfer of any Security to
the Registrar or any co-registrar at the office or agency of the Company
designated as Registrar or co-registrar pursuant to Section 2.3, and
satisfaction of the requirements for such transfer set forth in this Section
2.6, the Company shall execute, and the Trustee shall authenticate and deliver,
in the name of the designated transferee or transferees, one or more new
Securities of any authorized denominations and of a like aggregate principal
amount and bearing such restrictive legends as may be required by this
Indenture.

         Securities may be exchanged for other Securities of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at any such office or agency maintained by the
Company pursuant to Section 6.10. Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Securityholder making the exchange is entitled
to receive bearing numbers not contemporaneously outstanding.

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

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

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

         Neither the Company nor the Trustee nor any Registrar or any Company
registrar shall be required to exchange or register a transfer of (a) any
Securities for a period of fifteen (15) days next preceding any selection of
Securities to be redeemed or (b) any Securities or portions thereof selected for
redemption pursuant to Section 3.3 or (c) any Securities or portion thereof
surrendered for conversion pursuant to Article 4.

         So long as the Securities are eligible for book-entry settlement with
the Depositary, or unless otherwise required by law, all Securities that upon
initial issuance are beneficially owned by QIBs will be represented by a
Security in global form registered in the name of the Depositary or the nominee
of the Depositary (the "Global Note"). The transfer and exchange of beneficial
interests in the 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 the Global Note as set forth on the face
of the Security to reflect any such transfers. Except as provided

                                       13
<PAGE>

below, beneficial owners of the 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 Securities in global form.

         (b) Any Security in global form 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 Securities to be tradable on The PORTAL Market or as may
be required for the Securities to be tradable 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 Securities
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
Securities are subject.

         (c) Every Security that bears or is required under this Section 2.6(c)
to bear the legend set forth in this Section 2.6(c) (together with any Common
Stock issued upon conversion of the Securities and required to bear the legend
set forth in Section 2.6(d), collectively, the "Restricted Securities") shall be
subject to the restrictions on transfer set forth in this Section 2.6(c)
(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 Transfer Restricted Security, by such Holder's
acceptance thereof, agrees to be bound by all such restrictions on transfer. As
used in Sections 2.6(c) and 2.6(d), the term "transfer" encompasses any sale,
pledge, 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 Security (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 2.6(d), if
applicable) shall bear a legend in substantially the following form, unless such
Security 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:

                  THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
         TRANSACTION EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF
         1933 (THE "SECURITIES ACT"), AND THIS SECURITY MAY NOT BE OFFERED, SOLD
         OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
         APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS
         HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE
         EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT
         PROVIDED BY RULE 144A THEREUNDER.

                  THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE
         COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR
         OTHERWISE TRANSFERRED, ONLY (I) TO GENCORP INC., ITS

                                       14
<PAGE>

         SUBSIDIARIES, ITS AFFILIATES OR THE AFFILIATES OF ITS SUBSIDIARIES,
         (II) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED
         INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT)
         IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (III) PURSUANT
         TO RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), (IV) PURSUANT TO
         ANOTHER APPLICABLE EXEMPTION FROM REGISTRATION OR (V) PURSUANT TO AN
         EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH CASE
         IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE
         UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS
         REQUIRED TO, NOTIFY ANY SUBSEQUENT PURCHASER OF THIS SECURITY FROM IT
         OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. PRIOR TO A
         TRANSFER OF THIS SECURITY PURSUANT TO CLAUSE (III) OR (IV) ABOVE, THE
         HOLDER OF THIS SECURITY MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE
         COMPANY AND THE TRUSTEE OR THE TRANSFER AGENT, AS APPLICABLE, SUCH
         CERTIFICATES AND OTHER INFORMATION, INCLUDING A LEGAL OPINION, AS THEY
         MAY REASONABLY REQUIRE TO CONFIRM THAT ANY TRANSFER BY IT OF THIS
         SECURITY COMPLIES WITH THE FOREGOING RESTRICTIONS. THE HOLDER HEREOF,
         BY PURCHASING THIS SECURITY, REPRESENTS AND AGREES FOR THE BENEFIT OF
         THE COMPANY THAT IT WILL NOT, DIRECTLY OR INDIRECTLY, ENGAGE IN ANY
         HEDGING TRANSACTION WITH REGARD TO THIS SECURITY EXCEPT AS PERMITTED BY
         THE SECURITIES ACT.

                  THE FOREGOING LEGEND MAY BE REMOVED FROM THE SECURITY ON
         SATISFACTION OF THE CONDITIONS SPECIFIED IN THE INDENTURE.

         Any Security (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 which the conditions for removal of the foregoing legend
set forth therein have been satisfied may, upon surrender of such Security for
exchange to the Registrar in accordance with the provisions of this Section 2.6,
be exchanged for a new Security or Securities, of like tenor and aggregate
principal amount, which shall not bear the restrictive legend required by this
Section 2.6(c).

         Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in Section 2.6(b) and in this Section 2.6(c)), the 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 Global Note. 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.
Securityholders may hold their interests in the Global Note directly through DTC
if they are DTC participants, or indirectly through DTC participants.

                                       15
<PAGE>

         Securities in certificated form shall be transferred to all beneficial
owners in exchange for their beneficial interests in Global Notes only if (i)
the Depositary (x) notifies the Company that it is unwilling or unable to
continue as Depositary for any Global Note or (y) has ceased to be a clearing
agency registered under the Exchange Act and, in each case, a successor
depositary is not appointed by the Company within 90 days of such notice, (ii)
the Company, in its discretion, decides to discontinue use of the system of
book-entry transfer through the Depositary or (iii) a Default or an Event of
Default has occurred and is continuing. In any such case, the Company will
execute, and the Trustee, upon receipt of an Officers' Certificate for the
authentication and delivery of Securities, will authenticate and deliver,
Securities in certificated form, in aggregate principal amount equal to the
principal amount of the Global Note, in exchange for such Global Note.

         If a Security in certificated form is issued in exchange for any
portion of the 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 Security,
but will be payable on such interest Payment Date, subject to the provisions of
paragraphs 1 and 2 of the Security, only to the person to whom interest in
respect of such portion of the Global Note is payable in accordance with the
provisions of this Indenture and the Securities.

         Securities in certificated form issued in exchange for all or a part of
the Global Note pursuant to this Section 2.6 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
Securities in certificated form to the persons in whose names such Securities in
certificated form are so registered.

         At such time as all interests in the Global Note have been redeemed,
converted, canceled, exchanged for Securities in certificated form, or
transferred to a transferee who receives Securities 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 the Global Note is redeemed, converted, repurchased or canceled, the
principal amount of the Global Note shall, in accordance with the standing
procedures and instructions existing between the Depositary and the Custodian,
be appropriately reduced 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.

         (d) 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 such
Security 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 Securities that have been transferred pursuant to a registration
statement that has been declared effective

                                       16

under the Securities Act, or unless otherwise agreed by the Company in writing
with written notice thereof to the transfer agent:

                  THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
         TRANSACTION EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF
         1933 (THE "SECURITIES ACT"), AND THIS SECURITY MAY NOT BE OFFERED, SOLD
         OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
         APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS
         HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE
         EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT
         PROVIDED BY RULE 144A THEREUNDER.

                  THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE
         COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR
         OTHERWISE TRANSFERRED, ONLY (I) TO GENCORP INC., ITS SUBSIDIARIES, ITS
         AFFILIATES OR THE AFFILIATES OF ITS SUBSIDIARIES, (II) TO A PERSON WHOM
         THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING
         THE REQUIREMENTS OF RULE 144A, (III) PURSUANT TO RULE 144 UNDER THE
         SECURITIES ACT (IF AVAILABLE), (IV) PURSUANT TO ANOTHER APPLICABLE
         EXEMPTION FROM REGISTRATION OR (V) PURSUANT TO AN EFFECTIVE
         REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH CASE IN
         ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE
         UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS
         REQUIRED TO, NOTIFY ANY SUBSEQUENT PURCHASER OF THIS SECURITY FROM IT
         OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. PRIOR TO A
         TRANSFER OF THIS SECURITY PURSUANT TO CLAUSE (III) OR (IV) ABOVE, THE
         HOLDER OF THIS SECURITY MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE
         COMPANY AND THE TRUSTEE OR THE TRANSFER AGENT, AS APPLICABLE, SUCH
         CERTIFICATES AND OTHER INFORMATION, INCLUDING A LEGAL OPINION, AS THEY
         MAY REASONABLY REQUIRE TO CONFIRM THAT ANY TRANSFER BY IT OF THIS
         SECURITY COMPLIES WITH THE FOREGOING RESTRICTIONS. THE HOLDER HEREOF,
         BY PURCHASING THIS SECURITY, REPRESENTS AND AGREES FOR THE BENEFIT OF
         THE COMPANY THAT IT WILL NOT, DIRECTLY OR INDIRECTLY, ENGAGE IN ANY
         HEDGING TRANSACTION WITH REGARD TO THIS SECURITY EXCEPT AS PERMITTED BY
         THE SECURITIES ACT.

                  THE FOREGOING LEGEND MAY BE REMOVED FROM THE SECURITY ON
         SATISFACTION OF THE CONDITIONS SPECIFIED IN THE INDENTURE.

         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

                                       17
<PAGE>

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 2.6(d).

         (e) Any Security or Common Stock issued upon the conversion or exchange
of a Security 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
Securities or Common Stock, as the case may be, no longer being "restricted
securities" (as defined under Rule 144).

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

SECTION 2.7. REPLACEMENT SECURITIES.

         If any mutilated Security is surrendered to the Company or the Trustee,
or the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company and the Trustee such Security or indemnity as may be required by them to
save each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute, and upon its written request the Trustee shall
authenticate and deliver, in exchange for any such mutilated Security or in lieu
of any such destroyed, lost or stolen Security, a new Security of like tenor and
principal amount, bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, or is about to be redeemed by the
Company pursuant to Article 3, the Company in its discretion may, instead of
issuing a new Security, pay or redeem such Security, as the case may be.

         Upon the issuance of any new Securities under this Section 2.7, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

                                       18
<PAGE>

         Every new Security issued pursuant to this Section 2.7 in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all benefits of this Indenture equally and proportionately with any
and all other Securities duly issued hereunder.

         The provisions of this Section 2.7 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 2.8. OUTSTANDING SECURITIES.

         Securities outstanding at any time are all Securities authenticated by
the Trustee, except for those canceled by it, those delivered to it for
cancellation and those described in this Section 2.8 as not outstanding.

         If a Security is replaced pursuant to Section 2.7, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

         If the Paying Agent (other than the Company or an Affiliate of the
Company) holds on a redemption date, repurchase date or maturity date money
sufficient to pay the principal of, premium, if any, and accrued interest on
Securities payable on that date, then on and after that date such Securities
cease to be outstanding and interest (including Contingent Interest and
Liquidated Damages, if any) on them ceases to accrue; provided that if such
Securities are to be redeemed, notice of such redemption has been duly given
pursuant to this Indenture.

         Subject to the restrictions contained in Section 2.9, a Security does
not cease to be outstanding because the Company or an Affiliate of the Company
holds the Security.

SECTION 2.9. TREASURY SECURITIES.

         In determining whether the Holders of the required principal amount of
Securities have concurred in any notice, direction, waiver or consent,
Securities owned by the Company or any other obligor on the Securities or by any
Affiliate of the Company or of such other obligor shall be disregarded, except
that for purposes of determining whether the Trustee shall be protected in
relying on any such notice, direction, waiver or consent, only Securities which
a Trust Officer of the Trustee actually knows are so owned shall be so
disregarded. Securities so owned which have been pledged in good faith shall not
be disregarded if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to the Securities and that the pledgee is
not the Company or any other obligor upon the Securities or any Affiliate of the
Company or of such other obligor.

SECTION 2.10. TEMPORARY SECURITIES.

         Until definitive Securities are ready for delivery, the Company may
prepare and execute, and, upon the order of the Company, the Trustee shall
authenticate and deliver temporary Securities. Temporary Securities shall be
substantially in the form of definitive Securities but

                                       19
<PAGE>

may have variations that the Company with the consent of the Trustee considers
appropriate for temporary Securities. Every such temporary Security shall be
executed by the Company and authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Securities. Without unreasonable delay the Company will execute
and deliver to the Trustee definitive Securities and thereupon any or all
temporary Securities may be surrendered in exchange therefor, at each office or
agency maintained by the Company pursuant to Section 6.10 and the Trustee shall
authenticate and deliver in exchange for such temporary Securities an equal
aggregate principal amount of definitive Securities. Such exchange shall be made
by the Company at its own expense and without any charge therefor. Until so
exchanged, the temporary Securities shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities authenticated and
delivered hereunder.

SECTION 2.11. CANCELLATION.

         The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar, the Paying Agent and the Conversion Agent shall
forward to the Trustee any Securities surrendered to them for transfer,
exchange, payment or conversion. The Trustee and no one else shall cancel all
Securities surrendered for transfer, exchange, payment (including redemption or
repurchase), conversion or cancellation and shall dispose of cancelled
Securities in accordance with its procedures for the disposition of cancelled
Securities in effect as of the date of such disposition and thereupon deliver a
certificate of cancellation to the Company. The Company may not issue new
Securities to replace Securities it has paid or delivered to the Trustee for
cancellation or which have been converted.

SECTION 2.12. CUSIP NUMBERS.

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

                                   ARTICLE 3.

                            REDEMPTION AND REPURCHASE

SECTION 3.1. OPTIONAL REDEMPTION BY THE COMPANY.

         Beginning on January 19, 2010, the Company may redeem the Securities,
in whole at any time, or in part from time to time, for cash at a price equal to
100% of the principal amount of the Securities plus accrued but unpaid interest
(including Contingent Interest and Liquidated Damages, if any) up to but not
including the date of redemption payable in cash.

         In addition, on or after January 19, 2008, the Company may redeem the
Securities, in whole or in part, for cash at a price equal to 100% of the
principal amount of the Securities plus

                                       20
<PAGE>

accrued but unpaid interest (including Contingent Interest and Liquidated
Damages, if any) up to but not including the date of redemption, in the event
that the Closing Price of the Company's Common Stock for at least 20 Trading
Days in the period of 30 consecutive Trading Days ending on the last trading day
of the calendar month preceding the calendar month in which the notice of
redemption is properly mailed to Holders is more than 125% of the Conversion
Price on that 30th Trading Day.

SECTION 3.2. SELECTION TO REDEEM; NOTICE TO TRUSTEE.

         If the Company elects to redeem Securities pursuant to Section 3.1, it
shall notify the Trustee at least 30 days but not more than 60 days prior to the
redemption date as fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee) of the redemption date and the principal amount of
Securities to be redeemed. If fewer than all of the Securities are to be
redeemed, the record date relating to such redemption shall be selected by the
Company and given to the Trustee, which record date shall not be less than 10
days after the date of notice to the Trustee.

SECTION 3.3. SELECTION OF SECURITIES TO BE REDEEMED.

         If less than all of the Securities are to be redeemed, the Trustee
shall, not more than 60 days prior to the redemption date, select the Securities
to be redeemed by lot, pro rata or by another method the Trustee considers fair
and appropriate; provided that such method is not prohibited by any stock
exchange or market on which the Securities are then listed. The Trustee shall
make the selection from the Securities outstanding and not previously called for
redemption. Securities in denominations of $1,000 may only be redeemed in whole.
The Trustee may select for redemption portions (equal to $1,000 or any multiple
thereof) of the principal of Securities that have denominations larger than
$1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. If a
portion of a Holder's Securities is selected for redemption and that Holder
converts a portion of its Securities, the converted portion will be deemed to be
the portion first selected for redemption.

SECTION 3.4. NOTICE OF REDEMPTION.

         (7) that Holders who wish to convert Securities must satisfy the
requirements in paragraph 8 of the Securities;

         (8) that, unless the Company defaults in making the redemption payment,
interest on Securities called for redemption ceases to accrue on and after the
redemption date and the only remaining right of the Holder is to receive payment
of the redemption price upon presentation and surrender to the Paying Agent of
the Securities;

         (9) 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

SECTION 3.5. DEPOSIT OF REDEMPTION PRICE.

         On or prior to 10:00 a.m. (New York City time) on the Redemption Date,
the Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company or a Subsidiary or an Affiliate of either of them is acting as its own
Paying Agent, segregate and hold in trust) an amount of money sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an interest
Payment Date) accrued interest (including Contingent Interest and Liquidated
Damages, if any) on, all the Securities which are to be redeemed on that date
other than any Securities or portions of Securities called for redemption which
on or prior thereto which have been delivered by the Company to the Trustee for
cancellation or which have been converted.

         If any Security called for redemption is converted, any money deposited
with the Trustee or with any Paying Agent or segregated and held in trust for
the redemption of such Security shall (subject to any right of the Holder of
such Security or any predecessor Security to receive interest) be paid to the
Company as soon as practicable or, if then held by the Company, shall be
released from such trust.

                                       22
<PAGE>

SECTION 3.6. SECURITIES PAYABLE ON REDEMPTION DATE.

Once a notice of redemption has been given as aforesaid, the Securities called
for redemption shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, except for Securities which are converted in
accordance with this Indenture, and from and after such date (unless the Company
shall default in the payment of the Redemption Price and accrued interest,
including Contingent Interest and Liquidated Damages, if any) such Securities
shall cease to bear or accrue any interest (including Contingent Interest and
Liquidated Damages, if any). Upon surrender of any such Security for redemption
in accordance with said notice, such Security shall be paid by the Company at
the Redemption Price, together with accrued interest (including Contingent
Interest and Liquidated Damages, if any) to (but not including) the Redemption
Date; provided, however, that installments of interest whose stated maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities registered as such at the close of business on the relevant Record
Dates according to their terms.

SECTION 3.7. SECURITIES REDEEMED IN PART.

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

SECTION 3.8. CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION.

         In connection with any redemption of Securities, the Company may
arrange for the purchase and conversion of any Securities by an agreement with
one or more investment bankers or other purchasers (the "Purchase Party") to
purchase such Securities by paying to the Trustee in trust for the Holders, on
or before the Redemption Date, an amount not less than the applicable Redemption
Price of such Securities, together with interest (including Contingent Interest
and Liquidated Damages, if any) accrued to the Redemption Date. Notwithstanding
anything to the contrary contained in this Article 3, the obligation of the
Company to pay the Redemption Price of such Securities, together with interest
accrued to, but excluding, the Redemption Date shall be deemed to be satisfied
and discharged to the extent such amount is so paid by such Purchase Party. If
such an agreement is entered into, a copy of which shall be filed with the
Trustee prior to or on the Redemption Date, any Securities 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 to the contrary contained in Article
4) surrendered by such purchasers for conversion, all as of immediately prior to
the close of business on the Business Day prior to the Redemption Date (and the
right to convert any such Securities shall be deemed to have been 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

                                       23
<PAGE>

as it would monies deposited with it by the Company for the redemption of
Securities. Without the Trustee's prior written consent, no arrangement between
the Company and such purchasers for the purchase and conversion of any
Securities shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee as set forth in this Indenture,
and the Company agrees to indemnify the Trustee from, and hold it harmless
against, any loss, liability or expense arising out of or in connection with any
such arrangement for the purchase and conversion of any Securities between the
Company and such purchasers, including the costs and expenses incurred by the
Trustee in the defense of any claim or liability arising out of or in connection
with the exercise or performance of any of its powers, duties, responsibilities
or obligations under this Indenture. Nothing in the preceding sentence shall be
deemed to limit the rights and protections afforded to the Trustee in Article 9,
including, but not limited to, the right to the indemnification pursuant to
Section 9.7.

SECTION 3.9. REPURCHASE OF SECURITIES AT OPTION OF THE HOLDER.

         Securities shall be repurchased by the Company or by a Purchase Party,
if applicable, at the option of the Holder thereof, in accordance with the
provisions of paragraph 7 of the Securities on January 16, 2010, January 16,
2014 and January 16, 2019 (each, a "Repurchase Date") at a purchase price in
cash per Security equal to 100% of the aggregate principal amount thereof (the
"Repurchase Price"), together with accrued but unpaid interest (including
Contingent Interest and Liquidated Damages, if any), up to but not including the
Repurchase Date, subject to satisfaction by or on behalf of the Holder of the
requirements set forth in Section 3.11(b).

         Whenever in this Indenture there is a reference to the principal of any
Security as of any time, such reference shall be deemed to include reference to
the Repurchase Price payable in respect of such Security to the extent that such
Repurchase Price is, was or would be so payable at such time, and express
mention of the Repurchase Price in any provision of this Indenture shall not be
construed as excluding the Repurchase Price in those provisions of this
Indenture when such express mention is not made.

         Any rights of Holders, contractual or otherwise, arising under or
pursuant to any offer to repurchase Securities made by the Company under this
Section 3.9 shall be subordinated in right of payment to all Senior Indebtedness
to the same extent as the Securities are subordinated to Senior Indebtedness
under the provisions of Article 5 and such offer to repurchase shall provide
that, if at the time the Securities are required to be repurchased pursuant to
such offer, payment of the Securities is not permitted pursuant to the
provisions of Article 5, the Company shall use its best efforts to obtain all
necessary waivers from, or to repay in full, the holders of Senior Indebtedness
in order to permit such repurchase. Notwithstanding the foregoing, any failure
by the Company to comply with this Section 3.9 to offer to repurchase, or to
repurchase, the Securities shall be a default in the performance by the Company
hereunder.

SECTION 3.10. REPURCHASE OF SECURITIES AT OPTION OF THE HOLDER UPON CHANGE OF
              CONTROL.

         If at any time that Securities remain outstanding there shall have
occurred a Change of Control (as hereinafter defined), Securities shall be
repurchased by the Company or by a Purchase Party, if applicable, at the option
of the Holder thereof, at a purchase price in cash

                                       24
<PAGE>

equal to 100% of the principal amount thereof (the "Change of Control Repurchase
Price") plus accrued but unpaid interest (including Contingent Interest and
Liquidated Damages, if any), up to and including the Change of Control
Repurchase Date (as hereinafter defined), on the date (the "Change of Control
Repurchase Date") fixed by the Company that is not less than 45 days nor more
than 60 days after the date of the Company Notice (as hereinafter defined),
subject to satisfaction by or on behalf of the Holder of the requirements set
forth in Section 3.11(b); provided that if the Change in Control Purchase Date
is on or after a record date with respect to any interest payments, but on or
prior to the related interest payment date, Contingent Interest and Liquidated
Damages, if any, will be payable to the Holders in whose names the Securities
are registered at the close of business on the relevant record date.

         Whenever in this Indenture there is a reference to the principal of any
Security as of any time, such reference shall be deemed to include reference to
the Change in Control Repurchase Price payable in respect of such Security to
the extent that such Change of Control Repurchase Price is, was or would be so
payable at such time, and express mention of the Change in Control Repurchase
Price in any provision of this Indenture shall not be construed as excluding the
Change in Control Repurchase Price in those provisions of this Indenture when
such express mention is not made.

         Any rights of Holders, contractual or otherwise, arising under or
pursuant to any offer to repurchase Securities made by the Company under this
Section 3.10 shall be subordinated in right of payment to all Senior
Indebtedness to the same extent as the Securities are subordinated to Senior
Indebtedness under the provisions of Article 5 and such offer to repurchase
shall provide that, if at the time the Securities are required to be repurchased
pursuant to such offer, payment of the Securities is not permitted pursuant to
the provisions of Article 5, the Company shall use its best efforts to obtain
all necessary waivers from, or to repay in full, the holders of Senior
Indebtedness in order to permit such repurchase. Notwithstanding the foregoing,
any failure by the Company to comply with this Section 3.10 to offer to
repurchase, or to repurchase, the Securities shall be a default in the
performance by the Company hereunder.

         Notwithstanding the foregoing, the Company will not be required to make
a Change of Control offer upon a Change of Control if a third party makes the
Change of Control offer in the manner, at the times and otherwise in compliance
with the requirements set forth in this Section 3.10 applicable to a Change of
Control offer made by the Company, including any requirements to repay in full
all indebtedness under any Senior Indebtedness, or obtains the consents of the
lenders under such Senior Indebtedness to such Change of Control offer as
described in the next paragraph and purchases all Securities validly tendered
and not withdrawn under such Change of Control offer.

         Prior to the commencement of a Change of Control offer, but in any
event within 30 days following any Change of Control, the Company will:

          (1) (a) repay in full and terminate all commitments under the Credit
     Agreement and all other Senior Indebtedness the terms of which require
     repayment upon a Change of Control or (b) offer to repay in full and
     terminate all commitments under the Credit Agreement and all such other
     Senior Indebtedness and repay such indebtedness to each lender who has
     accepted such offer in full, or

                                       25
<PAGE>

          (2) obtain the requisite consents under the Credit Agreement and all
     such other Senior Indebtedness to permit the repurchase of the Securities
     as required under this Section 3.10.

         A "Change of Control" shall be deemed to have occurred at such time
after the original issuance of the Securities as any of the following occur:

         (1) any sale, lease, exchange or other transfer (in one transaction or
a series of related transactions) of all or substantially all of the assets of
the Company and its Subsidiaries, taken as a whole, to any Person or group of
related Persons, as defined in Section 13(d) of the Exchange Act (a "Group");

         (2) the approval by the holders of capital stock of the Company of any
plan or proposal for the liquidation or dissolution of the Company (whether or
not otherwise in compliance with the provisions of this Indenture);

         (3) any Person or Group shall become the owner, directly or indirectly,
beneficially or of record, of shares representing more than 45% of the Voting
Stock of the Company or any successor to all or substantially all of the
Company's assets; or

         (4) the first day on which a majority of the members of the Company's
Board of Directors are not Continuing Directors.

SECTION 3.11. NOTICE; METHOD OF EXERCISING REPURCHASE OR CHANGE OF CONTROL
REPURCHASE RIGHT.

         (a) In connection with any repurchase of Securities pursuant to Section
3.9 or 3.10, the Company shall give written notice of the Repurchase Date or
Change in Control Repurchase Date, as applicable, to the Holders (the "Company
Notice"). The Company Notice shall be sent by first-class mail to the Trustee
and to each Holder not less than 20 Business Days prior to any Repurchase Date
(the "Company Notice Date") or not more than 30 days after the occurrence of a
Change in Control, as the case may be. The notice shall include the form of a
Repurchase Notice (as defined below) to be completed by the Holder and shall
state:

         (1) the date of such Change of Control and, briefly, the events causing
such Change of Control;

         (2) the date by which the Repurchase Notice pursuant to this Section
3.11 must be given;

         (3) the Repurchase Date or Change in Control Repurchase Date, as the
case may be;

         (4) the Repurchase Price, Change in Control Repurchase Price or
Conversion Price and, to the extent known at the time of such notice, the amount
of Contingent Interest and Liquidated Damages, if any, that will be payable with
respect to the Securities on the Repurchase Date; and

         (5) the procedures that the Holder must follow to exercise rights under
Section 3.9 or Section 3.10, as the case may be.

                                       26
<PAGE>

         (b) A Holder may exercise its rights specified in Section 3.9 upon
delivery of a written notice of the exercise of such rights (a "Repurchase
Notice") to the Paying Agent at any time from the opening of business on the
date that is 20 Business Days prior to the Repurchase Date until the close of
business on the Repurchase Date, and a Holder may exercise its rights specified
in Section 3.10 upon delivery of a written notice of the exercise of such rights
(a "Change of Control Repurchase Notice") to the Paying Agent, which written
notice the Paying Agent shall promptly forward to the Company, at any time prior
to the close of business on the third Business Day prior to the Change of
Control Repurchase Date. Any Repurchase Notice or Change of Control Repurchase
Notice shall state:

         (1) the certificate number of each Security that the Holder will
deliver to be repurchased; and

         (2) the portion of the principal amount of each Security that the
Holder will deliver to be repurchased which portion must be $1,000 or an
integral multiple thereof; and that such Security shall be repurchased pursuant
to the terms and conditions specified in this Indenture. If the Security is held
in book-entry form, in lieu of the procedure set forth above, the Holder must
complete and deliver to the Depositary appropriate instructions pursuant to the
Depositary's repurchase conversion programs.

         In the case of a repurchase of a Security pursuant to Section 3.9
hereof, the delivery of such Security to the Paying Agent together with the
Repurchase Notice at any time prior to or on the Repurchase Date (together with
all necessary endorsements) at the office of the Paying Agent, shall be a
condition to the receipt by the Holder of the Repurchase Price therefor,
together with accrued but unpaid interest (including Contingent Interest and
Liquidated Damages, if any); provided, however, that such Repurchase Price,
together with accrued but unpaid interest (including Contingent Interest and
Liquidated Damages, if any), shall be so paid pursuant to Section 3.9 only if
the Security so delivered to the Paying Agent shall conform in all respects to
the description thereof set forth in the related Repurchase Notice, as
determined by the Company.

         In the case of a repurchase of a Security pursuant to Section 3.10
hereof, the delivery of such Security to the Paying Agent together with the
Change of Control Repurchase Notice at any time prior to the third Business Day
prior to the Change of Control Repurchase Date (together with all necessary
endorsements) at the office of the Paying Agent shall be a condition to the
receipt by the Holder of the Repurchase Price therefor; provided, however, that
such Repurchase Price shall be so paid pursuant to Section 3.10 only if the
Security so delivered to the Paying Agent shall conform in all respects to the
description thereof set forth in the related Change of Control Repurchase Notice
as determined by the Company.

         The Company or the Purchase Party shall repurchase from the Holder
thereof, pursuant to Section 3.9 or Section 3.10, a portion of a Security if the
principal amount of such portion is $1,000 or an integral multiple of $1,000.
Provisions of this Indenture that apply to the repurchase of all of a Security
pursuant to Sections 3.9 through 3.16 also apply to the repurchase of such
portion of such Security.

                                       27
<PAGE>

         Notwithstanding anything herein to the contrary, any Holder delivering
to the Paying Agent the Repurchase Notice or Change in Control Repurchase
Notice, shall have the right to withdraw such Repurchase Notice in whole or in a
portion thereof that is $1,000 or an integral multiple thereof at any time prior
to the close of business on the Business Day prior to the Repurchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 3.12.

         The Paying Agent shall promptly notify the Company and any Purchase
Party of the receipt by it of any Repurchase Notice or Change in Control
Repurchase Notice, as the case may be, or written withdrawal thereof.

SECTION 3.12. EFFECT OF REPURCHASE NOTICE OR CHANGE IN CONTROL REPURCHASE
NOTICE.

         Upon receipt by the Paying Agent of the Repurchase Notice or Change in
Control Purchase Notice specified in Section 3.11(b), the Holder of the Security
in respect of which such Repurchase Notice or Change in Control Repurchase
Notice was given shall (unless such Repurchase Notice or Change in Control
Repurchase Notice is withdrawn as specified below) thereafter be entitled to
receive solely the Repurchase Price or Change in Control Repurchase Price,
together with accrued but unpaid interest (including Contingent Interest and
Liquidated Damages, if any) with respect to such Security. Such Repurchase Price
or Change in Control Repurchase Price, as applicable, together with accrued but
unpaid interest (including Contingent Interest and Liquidated Damages, if any)
thereon, to but not including the Repurchase Date or Change in Control
Repurchase Date, as the case may be, shall be paid to such Holder promptly
following the later of (i) the Repurchase Date or Change in Control Repurchase
Date with respect to such Security (provided the conditions in Sections 3.11(b)
have been satisfied) and (ii) the time of delivery of such Security to the
Paying Agent by the Holder thereof in the manner required by Section 3.11(b).
Securities in respect of which a Repurchase Notice or Change in Control
Repurchase Notice, as the case may be, has been given by the Holder thereof may
not be converted into shares of Common Stock on or after the date of the
delivery of such Repurchase Notice or Change in Control Repurchase Notice, as
the case may be, unless such Repurchase Notice or Change in Control Repurchase
Notice, as the case may be, has first been validly withdrawn.

         A Repurchase Notice or Change in Control Repurchase Notice, as the case
may be, may be withdrawn by means of a written notice of withdrawal delivered by
the Holder, with such Holder's signature guaranteed in a manner satisfactory to
the Paying Agent, to the office of the Paying Agent at any time prior to the
close of business on the Business Day prior to the Repurchase Date or Change in
Control Repurchase Date, as the case may be, to which it relates, specifying:

         (1) the certificate number of each Security in respect of which such
notice of withdrawal is being submitted;

         (2) the principal amount of the Security or portion thereof with
respect to which such notice of withdrawal is being submitted; and

                                       28
<PAGE>

         (3) the principal amount, if any, of such Security that remains subject
to the original Repurchase Notice or Change in Control Repurchase Notice and
that has been or will be delivered for repurchase by the Company.

         There shall be no purchase of any Securities pursuant to Section 3.9 or
Section 3.10 or redemption pursuant to Section 3.1 if there has occurred prior
to, on or after, as the case may be, the giving, by the Holders of such
Securities, of the required Repurchase Notice (or Change in Control Repurchase
Notice, as the case may be) and is continuing an Event of Default (other than a
default in the payment of the Repurchase Price or Change in Control Repurchase
Price, as the case may be). The Paying Agent will promptly return to the
respective Holders thereof any Securities (x) with respect to which a Repurchase
Notice or Change in Control Repurchase Notice, as the case may be, has been
withdrawn in compliance with this Indenture, or (y) held by it during the
continuance of an Event of Default (other than a default in the payment of the
Repurchase Price or Change in Control Repurchase Price, as the case may be) in
which case, upon such return, the Repurchase Notice or Change in Control
Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

SECTION 3.13. DEPOSIT OF REPURCHASE PRICE OR CHANGE IN CONTROL REPURCHASE PRICE.

         If the Security is held in book-entry form, in lieu of the procedure
set forth above, the Holder must complete and deliver to the Depositary
appropriate instructions pursuant to the Depositary's repurchase conversion
programs.

         On or before the Repurchase Date or Change in Control Repurchase Date,
as the case may be, the Company shall deposit with the Trustee or with the
Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of
them is acting as the Paying Agent, shall segregate and hold in trust as
provided in Section 2.4) an amount of money sufficient to pay the aggregate
Repurchase Price or Change in Control Repurchase Price, as the case may be,
including accrued but unpaid interest (including Contingent Interest and
Liquidated Damages, if any) thereon to but not including the Repurchase Date or
Change in Control Repurchase Date, as the case may be, of all the Securities or
portions thereof that are to be repurchased as of such Repurchase Date or Change
in Control Repurchase Date, as the case may be. The manner in which the deposit
required by this Section 3.13 is made by the Company shall be at the option of
the Company; provided that such deposit shall be made in a manner such that the
Trustee or the Paying Agent shall have immediately available funds on the
Repurchase Date or Change in Control Repurchase Date, as the case may be;
provided further, that if such payment is made on the Repurchase Date or Change
in Control Repurchase Date, as the case may be, 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.

         If the Paying Agent holds, in accordance with the terms hereof, money
sufficient to pay the Repurchase Price or Change in Control Repurchase Price of
any Security tendered for repurchase on the Business Day prior to the Repurchase
Date or Change in Control Repurchase Date, as the case may be, then, on and
after the Repurchase Date or Change in Control Repurchase Date, as the case may
be, such Security will cease to be outstanding and interest on such Security
will cease to accrue and will be deemed paid, whether or not such Security is

                                       29
<PAGE>

delivered to the Paying Agent, and all other rights of the Holder in respect
thereof shall terminate (other than the right to receive the Repurchase Price or
Change in Control Repurchase Price, as the case may be, upon delivery of such
Security).

SECTION 3.14. SECURITIES REPURCHASED IN PART.

         Any Security that is to be repurchased only in part shall be
surrendered at the office of the Paying Agent (with due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing), and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security, without service charge,
a new Security or Securities, or such authorized denomination or denominations
as may be requested by such Holder, in aggregate principal amount equal to, and
in exchange for, the portion of the principal amount of the Security so
surrendered that is not repurchased.

SECTION 3.15. COMPLIANCE WITH SECURITIES LAWS UPON REPURCHASE OF SECURITIES.

         In connection with any offer to repurchase or repurchase of Securities
under Section 3.9 or Section 3.10 hereof (provided that such offer or repurchase
constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as
used herein, includes any successor provision thereto) at the time of such offer
or repurchase), the Company shall (i) comply with Rule 13e-4 and Rule 14e-1
under the Exchange Act, if applicable, (ii) file the related Schedule TO (or any
successor schedule, form or report) under the Exchange Act, and (iii) otherwise
comply with all federal and state securities laws so as to permit the rights of
the Holders and obligations of the Company under Sections 3.9 through 3.15 to be
exercised at the time and in the manner specified therein.

SECTION 3.16. REPAYMENT TO THE COMPANY.

         Subject to the provisions of Section 5.7, to the extent that the
aggregate amount of cash deposited by the Company pursuant to Section 3.13
exceeds the aggregate Repurchase Price or Change in Control Repurchase Price, as
the case may be, of the Securities or portions thereof to be repurchased, then,
promptly after the Business Day following the Repurchase Date or Change in
Control Repurchase Date, as the case may be, the Trustee or the Paying Agent, as
the case may be, shall return any such excess to the Company.

                                       30
<PAGE>

consecutive Trading Days ending on the last Trading Day of the Quarter
immediately preceding such Quarter (appropriately adjusted to take into account
the occurrence, during such 20 Trading Day period, of any event requiring
adjustment of the Conversion Price under this Indenture) is more than 120% of
the Conversion Price on such 30th Trading Day;

         (b) the Security has been called for redemption by the Company pursuant
to Section 3.1 and the redemption has not yet occurred;

         (c) during the five Trading Day period immediately after any period of
five consecutive Trading Days in which the Trading Price for each Trading Day in
such period was less than 95% of the product of the Closing Price per share of
Common Stock on such Trading Day multiplied by the number of shares of Common
Stock issuable (assuming satisfaction of conditions to conversion) upon
conversion of $1,000 in principal amount of the Securities (the "Trading Price
Condition"); provided, that if on the date of any conversion pursuant to the
Trading Price Condition, the Closing Price is greater than the effective
Conversion Price but less than 120% of the then effective Conversion Price, then
such Holder shall receive, in lieu of shares of Common Stock based on the
Conversion Rate, shares of Common Stock with a value equal to the principal
amount of such Holder's Securities plus accrued but unpaid interest (including
Contingent Interest and Liquidated Damages, if any) as of the Conversion Date (a
"Principal Value Conversion"). Shares of Common Stock delivered upon a Principal
Value Conversion will be valued at the greater of the Effective Conversion Price
on the Conversion Date and the applicable Closing Price as of the third day
after the Conversion Date. The Company shall deliver such shares of Common Stock
no later than the third Business Day following the determination of the
applicable Closing Price. The "Effective Conversion Price" is, as of any date of
determination, a dollar amount (initially $15.43) derived by dividing $1,000 by
the Conversion Rate then in effect (assuming a Conversion Date eight Trading
Days prior to the date of determination);

         (d) (i) an issuance of rights, warrants or options referred to in
Section 4.6(b) occurs; or (ii) a distribution referred to in Section 4.6(c)
occurs where the fair market value of such distribution per share of Common
Stock (as determined by the Board of Directors of the Company, which
determination shall be conclusive evidence of such fair market value) exceeds
10% of the Closing Price per share of Common Stock on the Trading Day
immediately preceding the date of declaration of such distribution; or

         (e) (i) the Company is party to a consolidation, merger, share
exchange, sale of all or substantially all of its assets or other similar
transaction pursuant to which the Common Stock is subject to conversion into
shares of stock (other than Common Stock of the Company), other securities or
property (including cash) subject to Section 4.12 and (ii) the conversion of
such Security occurs at any time from and after the date that is 15 days prior
to the date of the anticipated effective time of such transaction until and
including the date that is 15 days after the actual effective date of such
transaction; provided, however, that if such conversion occurs after the
effective date of such transaction, the Holder will receive on conversion the
consideration determined in accordance with Section 4.12.

         In the case of the foregoing clause (c), the Trustee (or other
Conversion Agent appointed by the Company) shall have no obligation to determine
the Trading Price unless the Company

                                       31
<PAGE>

has requested such a determination; and the Company shall have no obligation to
make such request unless a Holder provides it with reasonable evidence that the
Trading Price per $1,000 principal amount of such series of Securities would be
less than 95% of the product of the Closing Price per share of Common Stock on
such Trading Date multiplied by the number of shares of Common Stock issuable
(assuming satisfaction of conditions to conversion) upon conversion of $1,000 in
principal amount of the Securities. If such evidence is provided, the Company
shall instruct the Trustee (or other Conversion Agent) to determine the Trading
Price of the Securities beginning on the next Trading Day and on each successive
Trading Day until the Trading Price per $1,000 principal amount of such
Securities is greater than or equal to 95% of the product of the Closing Price
per share of Common Stock on such Trading Date multiplied by the number of
shares of Common Stock issuable (assuming satisfaction of conditions to
conversion) upon conversion of $1,000 in principal amount of the Securities;
provided that the Trustee shall be under no duty or obligation to make the
calculations described in the foregoing clause (c) or to determine whether the
Securities are convertible pursuant to such section. The Company shall make the
calculations described in the foregoing clause (c), using the Trading Price
provided by the Trustee or a member of the New York Stock Exchange.

         The Trustee shall be entitled at its sole discretion to consult with
the Company and to request the assistance of and rely upon the Company in
connection with the Trustee's duties and obligations pursuant to the foregoing
clause (c) (including without limitation the calculation or determination of the
Trading Price), and the Company agrees, if requested by the Trustee, to
cooperate with, and provide assistance to, the Trustee in carrying out its
duties under the foregoing clause (c); provided, however, that nothing herein
shall be construed to relieve the Trustee of its duties pursuant to the
foregoing clause (c).

         In the case of the foregoing clauses (d)(i) and (ii), the Company shall
cause a notice of such issuance or distribution to be filed with the Trustee and
the Conversion Agent and to be mailed to each Holder of Securities at its
address appearing on the list provided for in Section 2.5, at least 20 days
prior to the Ex-Dividend Date for such issuance or distribution. Once the
Company has given such notice, Holders may surrender their Securities for
conversion at any time thereafter until the earlier of the close of business on
the Business Day prior to the Ex-Dividend Date or the Company's announcement
that such issuance or distribution will not take place. This provision shall not
apply if the Holder of a Security is otherwise entitled to participate in the
distribution without conversion.

         The "Ex-Dividend Date" for any such issuance or distribution means the
date immediately prior to the commencement of "ex-dividend" trading for such
issuance or distribution on The New York Stock Exchange or such other national
securities exchange or The Nasdaq Stock Market or similar system of automated
dissemination of quotations of securities prices on which the Common Stock is
then listed or quoted.

         The number of shares of Common Stock issuable upon conversion of a
Security shall be determined by dividing the principal amount of the Security or
portion thereof surrendered for conversion by the Conversion Price in effect on
the Conversion Date. The initial Conversion Price is set forth in paragraph 8 of
the Securities and is subject to adjustment as provided in this Article 4.

                                       32
<PAGE>

         A Holder may convert a portion of a Security equal to $1,000 or any
integral multiple thereof. Provisions of this Indenture that apply to conversion
of all of a Security also apply to conversion of a portion of a Security.

         If a Security is called for redemption pursuant to Article 3, the right
to convert such Security shall terminate at the close of business on the third
Business Day before the redemption date for such Security (unless the Company
shall default in making the redemption payment then due, in which case the
conversion right shall terminate on the date such Default is cured and such
Security is redeemed). A Security in respect of which a Holder has delivered a
Repurchase Notice or a Change in Control Repurchase Notice pursuant to Section
3.11 exercising the option of such Holder to require the Company to repurchase
such Security may be converted only if such Repurchase Notice or Change in
Control Repurchase Notice, as the case may be, is withdrawn by a written notice
of withdrawal delivered to the Paying Agent prior to the close of business on
the Repurchase Date or prior to the close of business on the Change in Control
Repurchase Date, as the case may be, in accordance with Section 3.11.

         A Holder of Securities is not entitled to any rights of a holder of
Common Stock until such Holder has converted its Securities into Common Stock
and, upon such conversion, only to the extent such Securities are deemed to have
been converted into Common Stock pursuant to this Article 4.

SECTION 4.2. CONVERSION PROCEDURE.

         To convert a Security, a Holder must (i) complete and manually sign the
conversion notice on the back of the Security and deliver such notice to the
Conversion Agent, (ii) surrender the Security to the Conversion Agent, (iii)
furnish appropriate endorsements and transfer documents to the Registrar or the
Conversion Agent, (iv) pay any transfer or other tax, if required by Section 4.4
and (v) if the Security is held in book-entry form, complete and deliver to the
Depositary appropriate instructions pursuant to the Depositary's book-entry
conversion programs. The date on which the Holder satisfies all of the foregoing
requirements is the conversion date. As soon as practicable after the conversion
date, the Company shall deliver to the Holder through the Conversion Agent a
certificate for the number of whole shares of Common Stock issuable upon the
conversion and cash in lieu of any fractional shares pursuant to Section 4.5.

         The person in whose name the certificate is registered shall be deemed
to be a stockholder of record on the conversion date; provided, however, that no
surrender of a Security on any date when the stock transfer books of the Company
shall be closed shall be effective to constitute the person or persons entitled
to receive the shares of Common Stock upon such conversion as the record holder
or holders of such shares of Common Stock on such date, but such surrender shall
be effective to constitute the person or persons entitled to receive such shares
of Common Stock as the record holder or holders thereof for all purposes at the
close of business on the next succeeding day on which such stock transfer books
are open; provided, further, that such conversion shall be at the Conversion
Price in effect on the date that such Security shall have been surrendered for
conversion, as if the stock transfer books of the Company had not been closed.
Upon conversion of a Security, such person shall no longer be a Holder of such
Security.

                                       33
<PAGE>

         No payment or adjustment will be made for accrued interest (including
Contingent Interest and Liquidated Damages, if any) on converted Security or for
dividends or distributions on shares of Common Stock issued upon conversion of a
Security, but if any Holder surrenders a Security for conversion between the
record date for the payment of an installment of interest (including Contingent
Interest and Liquidated Damages, if any) and the next interest Payment Date,
then, notwithstanding such conversion, the interest (including Contingent
Interest and Liquidated Damages, if any) payable on such interest Payment Date
shall be paid to the Holder of such Security on such record date. In such event,
such Security, when surrendered for conversion, must be accompanied by delivery
of a check payable to the Conversion Agent in an amount equal to the interest
(including Contingent Interest and Liquidated Damages, if any) payable on such
interest Payment Date on the portion so converted. If such payment does not
accompany such Security, the Security shall not be converted; provided, however,
that no such check shall be required if such Security has been called for
redemption on a redemption date within the period between and including such
record date and such interest Payment Date. If the Company defaults in the
payment of interest (including Contingent Interest and Liquidated Damages, if
any) payable on the interest Payment Date, the Conversion Agent shall repay such
funds to the Holder.

         Upon surrender of a Security that is converted in part, the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder, a
new Security equal in principal amount to the unconverted portion of the
Security surrendered.

SECTION 4.3. ADJUSTMENTS BELOW PAR VALUE.

         Before taking any action which would cause an adjustment decreasing the
Conversion Price so that the shares of Common Stock issuable upon conversion of
the Securities would be issued for less than the par value of such Common Stock,
the Company will take all corporate action which may be necessary in order that
the Company may validly and legally issue fully paid and nonassessable shares of
such Common Stock at such adjusted Conversion Price.

SECTION 4.4. TAXES ON CONVERSION.

         If a Holder converts a Security, the Company shall pay any documentary,
stamp or similar issue or transfer tax due on the issue of shares of Common
Stock upon such conversion. However, the Holder shall pay any such tax which is
due because the Holder requests the shares to be issued in a name other than the
Holder's name. The Conversion Agent may refuse to deliver the certificates
representing the Common Stock being issued in a name other than the Holder's
name until the Conversion Agent receives a sum sufficient to pay any tax which
will be due because the shares are to be issued in a name other than the
Holder's name. Nothing herein shall preclude any tax withholding required by law
or regulations.

SECTION 4.5. COMPANY TO PROVIDE STOCK.

         The Company shall, prior to issuance of any Securities hereunder, and
from time to time as may be necessary, reserve, out of its authorized but
unissued Common Stock a sufficient number of shares of Common Stock to permit
the conversion of all outstanding Securities for

                                       34
<PAGE>
shares of Common Stock. The shares of Common Stock or other securities issued
upon conversion of the Securities shall bear any legend required in accordance
with Section 2.6(d).

         No fractional shares of Common Stock or scrip representing fractional
shares shall be issued upon conversion of Securities. If more than one Security
shall be surrendered for conversion at one time by the same holder, the number
of full shares which shall be issuable upon conversion shall be computed on the
basis of the aggregate principal amount of the Securities (or specified portions
thereof to the extent permitted hereby) so surrendered. If any fractional share
of Common Stock would be issuable upon the conversion of any Security or
Securities, the Company shall make an adjustment thereof in cash at the current
market value thereof. For these purposes, the current market value of a share of
Common Stock shall be the Closing Price on the first day (which is not a Legal
Holiday) immediately preceding the day on which the Securities (or specified
portions thereof) are deemed to have been converted.

         The Company covenants that all shares of Common Stock delivered upon
conversion of the Securities shall be newly issued shares or treasury shares,
shall be duly authorized, validly issued, fully paid and non-assessable and
shall be free from preemptive rights and free of any lien or adverse claim.

         The Company will endeavor promptly to comply with all federal and state
securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Securities, if any, and will list or cause to have quoted such
shares of Common Stock on each national securities exchange or in the
over-the-counter market or such other market on which the Common Stock is then
listed or quoted.

SECTION 4.6. ADJUSTMENT OF CONVERSION PRICE.

         The conversion price (the "Conversion Price") shall be that price set
forth in paragraph 8 of the form of Security attached hereto as Exhibit A and
shall be adjusted from time to time by the Company as follows:

         (a) In case the Company shall (i) pay a dividend or other distribution
in shares of Common Stock to holders of Common Stock, (ii) subdivide its
outstanding Common Stock into a greater number of shares, (iii) combine its
outstanding Common Stock into a smaller number of shares or (iv) reclassify its
outstanding Common Stock, the Conversion Price in effect immediately prior
thereto shall be adjusted so that the Holder of any Security thereafter
surrendered for conversion shall be entitled to receive the number of shares of
Common Stock which it would have owned or have been entitled to receive had such
Security been converted immediately prior to the happening of such event. An
adjustment made pursuant to this subsection (a) shall become effective
immediately after the record date in the case of a dividend or distribution and
shall become effective immediately after the effective date in the case of
subdivision, combination or reclassification.

         (b) In case the Company shall issue to all holders of its Common Stock,
rights, warrants or options entitling such holders (for a period commencing no
earlier than the record date described below and expiring not more than 60 days
after such record date) to subscribe for or purchase shares of Common Stock (or
securities convertible into Common Stock) at a price per share less than the
current market price

                                       35
<PAGE>

per share of Common Stock (as determined in accordance with subsection (g)
below) at the record date for the determination of stockholders entitled to
receive such rights, warrants or options, the Conversion Price in effect
immediately prior thereto shall be adjusted so that the Conversion Price shall
equal the price determined by multiplying the Conversion Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the number of shares of Common Stock outstanding on such record date,
plus the number of shares which the aggregate subscription or purchase price for
the total number of shares of Common Stock offered by the rights, warrants or
options so issued (or the aggregate conversion price of the convertible
securities offered by such rights, warrants or options) would purchase at such
current market price, and the denominator of which shall be the number of shares
of Common Stock outstanding on such record date plus the number of additional
shares of Common Stock offered by such rights, warrants or options (or into
which the convertible securities so offered by such rights, warrants or options
are convertible). Such adjustment shall be made successively whenever any such
rights, warrants or options are issued, and shall become effective immediately
after such record date. If at the end of the period during which such rights,
warrants or options are exercisable not all rights, warrants or options shall
have been exercised, the adjusted Conversion Price shall be immediately
readjusted to what it would have been upon application of the foregoing
adjustment substituting the number of additional shares of Common Stock actually
issued (or the number of shares of Common Stock issuable upon conversion of
convertible securities actually issued) for the total number of shares of Common
Stock offered (or the convertible securities offered).

         (c) In case the Company shall distribute to all holders of its Common
Stock any shares of capital stock of the Company (other than Common Stock) or
evidences of its indebtedness, cash, other securities or other assets, or shall
distribute to all holders of its Common Stock, rights, warrants or options to
subscribe for or purchase any of its securities (excluding: (i) rights, options,
warrants and other securities referred to in subsections (b) above or (d), (e)
or (h) below; and (ii) those dividends, distributions, subdivisions and
combinations referred to in subsection (a) above); then in each such case the
Conversion Price shall be adjusted so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the date of such distribution or purchase by a fraction, the numerator of which
shall be the current market price per share (as defined in subsection (g) below)
of the Common Stock on the record date mentioned below less the fair market
value on such record date (as determined by the Board of Directors of the
Company, whose determination shall be conclusive evidence of such fair market
value) of the portion of the capital stock or evidences of indebtedness,
securities or assets so distributed or of such rights, warrants or options, in
each case as applicable to one share of Common Stock, and the denominator of
which shall be the current market price per share (as defined in subsection (g)
below) of the Common Stock on such record date. Such adjustment shall become
effective immediately after the record date for the determination of
stockholders entitled to receive such distribution.

         (d) In the event the Company pays a dividend or makes a distribution to
all holders of its Common Stock consisting of publicly-traded capital stock of
any class or series, or similar equity interests, of or relating to a Subsidiary
or other business unit of the Company, the Conversion Price shall be adjusted,
if at all, in accordance with the formula:

                           CP' =         CP
                                    -------------

                                       36
<PAGE>

                                     (1+    F     )
                                        ----------
                                            M
where:

                  CP' = the adjusted Conversion Price

                  CP  = the current Conversion Price

                  M = the average of the Closing Prices of the Common Stock for
the 10 trading days commencing on and including the fifth trading day after the
date on which "ex-dividend trading" commences for such dividend or distribution
on The New York Stock Exchange or such other national or regional exchange or
market which such securities are then listed or quoted.

                  F = the average of the Closing Prices of the securities
distributed in respect of each share of Common Stock for which this Section
4.6(e) applies for the 10 trading days commencing on and including the fifth
trading day after the date on which "ex-dividend trading" commences for such
dividend or distribution on The New York Stock Exchange or such other national
or regional exchange or market which such securities are then listed or quoted.

         (e) In case the Company shall declare a cash dividend or distribution
greater than $0.03 per quarter to all the holders of Common Stock, the
Conversion Price shall be decreased so that the Conversion Price shall equal the
price determined by multiplying the Conversion Price in effect immediately prior
to the record date for such dividend or distribution by a fraction,

         (i) the numerator of which shall be the average Closing Price of the
         Company's Common Stock for the three consecutive Trading Days ending on
         the date immediately preceding the record date for such dividend or
         distribution (the "Pre-Dividend Sale Price"), minus the aggregate of
         the full amount of such cash dividend or distribution applicable to one
         share of Common Stock less $0.03 per fiscal quarter, and

         (ii) the denominator of which shall be the Pre-Dividend Sale Price;

such adjustment to become effective immediately after the record date for such
dividend or distribution; provided that no adjustment to the Conversion Price or
the ability of a Holder of a Security to convert will be made pursuant to this
Section 4.6(e) if the Company provides that Holders of Securities will
participate in such cash dividend or distribution on an as-converted basis
without conversion.

         (f) In case the Company or any of its Subsidiaries shall repurchase
(including by way of tender or exchange offer, other than an odd lot tender
offer) shares of Common Stock, and the fair market value of the sum of (i) the
aggregate consideration paid for such Common Stock, (ii) the aggregate fair
market value of cash dividends and distributions paid within the twelve (12)
months preceding the date of purchase of such shares of Common Stock in respect
of which no adjustment pursuant to this Section 4.6 previously has been made,
and (iii) the aggregate fair market value of any amounts previously paid for the
repurchase of Common Stock of a type described in this paragraph (f) within the
twelve (12) months preceding the date of purchase of such shares of Common Stock
in respect of which no adjustment pursuant to this Section 4.6 previously has
been made, exceeds 10% of aggregate Market Capitalization on the date of, and
after giving effect to, such repurchase, then the Conversion Price shall be
adjusted so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately

                                       37
<PAGE>

prior to the date of such distribution or purchase by a fraction, the numerator
of which shall be the current market price per share (as defined in subsection
(g) below) of the Common Stock on the date of such repurchase, less the quotient
obtained by dividing the Aggregate Market Premium involved in such repurchase
(as defined hereinafter) by the difference between the number of shares of
Common Stock outstanding before such repurchase and the number of shares of
Common Stock the subject of such repurchase, and the denominator of which shall
be the current market price per share (as defined in subsection (g) below) of
the Common Stock on the date of such repurchase. Such adjustment shall become
effective immediately after the date of such repurchase. For purposes of this
subsection (f), the "Aggregate Market Premium" is the excess, if any, of the
aggregate repurchase price paid for all such Common Stock over the aggregate
current market value per share (as defined in subsection (g) below) of all such
repurchased stock, determined with respect to each share involved in each such
repurchase as of the date of repurchase with respect to such share.

         (g) For the purpose of any computation under subsections (b), (c) and
(f) above, the current market price per share of Common Stock on any date shall
be deemed to be the average of the Closing Prices for 20 consecutive Trading
Days commencing 30 Trading Days before the record date with respect to any
distribution, issuance or other event requiring such computation. As used
herein, the term "Trading Days" with respect to Common Stock means (i) if the
Common Stock is listed or admitted for trading on any national securities
exchange, days on which such national securities exchange is open for business
or (ii) if the Common Stock is quoted on a system of automated dissemination of
quotations of securities prices, days on which trades may be made on such
system.

         (h) If the Company has implemented or implements a Stockholder Rights
Plan (as defined below), the Company agrees that such Stockholder Rights Plan
will provide that upon any conversion of the Securities by any Holder prior to a
Trigger Event (as defined below), the Holders shall receive the rights, warrants
or options issued under such plan. Rights, warrants or options distributed by
the Company to all holders of Common Stock entitling the holders thereof to
subscribe for or purchase shares of the Company's capital stock (either
initially or under certain circumstances), which rights, warrants or options,
until the occurrence of a specified event or events (a "Trigger Event"):

                  (i)      are deemed to be transferred with such shares of
                           Common Stock,

                  (ii)     are not exercisable, and

                  (iii)    are also issued in respect of future issuances of
                           Common Stock,

(a "Stockholder Rights Plan") shall not be deemed distributed for purposes of
this Section 4.6 and no adjustment to the Conversion Price shall be required to
be made until the occurrence of the earliest Trigger Event. In addition, in the
event of any Trigger Event with respect thereto, that shall have resulted in an
adjustment to the Conversion Price under this Section 4.6, (1) in the case of
any such rights, warrants or options which shall all have been redeemed or
repurchased without exercise by any holders thereof, the Conversion Price shall
be readjusted upon such final redemption or repurchase to give effect to such
distribution or Trigger Event, as the case may be, as though it were a cash
distribution, equal to the per share redemption or repurchase price

                                       38
<PAGE>

received by a holder of Common Stock with respect to such rights, warrants or
options (assuming such holder had retained such rights, warrants or options),
made to all holders of Common Stock as of the date of such redemption or
repurchase, and (2) in the case of any such rights, warrants or options all of
which shall have expired without exercise by any holder thereof, the Conversion
Price shall be readjusted as if such issuance had not occurred.

         In any case in which this Section 4.6 shall require that an adjustment
be made immediately following a record date established for purposes of this
Section 4.6, the Company may elect to defer (but only until five Business Days
following the filing by the Company with the Trustee of the certificate
described in Section 4.10) issuing to the holder of any Security converted after
such record date the shares of Common Stock and other capital stock of the
Company issuable upon such conversion over and above the shares of Common Stock
and other capital stock of the Company issuable upon such conversion only on the
basis of the Conversion Price prior to adjustment; and, in lieu of the shares
the issuance of which is so deferred, the Company shall issue or cause its
transfer agents to issue due bills or other appropriate evidence of the right to
receive such shares.

SECTION 4.7. NO ADJUSTMENT.

         No adjustment in the Conversion Price shall be required unless the
adjustment would require an increase or decrease of at least 1% in the
Conversion Price as last adjusted; provided, however, that any adjustments which
by reason of this Section 4.7 are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Article 4 shall be made to the nearest cent or to the nearest
one-hundredth of a share, as the case may be.

         No adjustment need be made for rights to purchase Common Stock or
issuances of Common Stock pursuant to a Company plan for reinvestment of
dividends or interest.

         No adjustment need be made for a change in the par value or a change to
no par value of the Common Stock.

         To the extent that the Securities become convertible into cash, no
adjustment need be made thereafter as to the cash. Interest will not accrue on
the cash.

SECTION 4.8. EQUIVALENT ADJUSTMENTS.

         In the event that, as a result of an adjustment made pursuant to
Section 4.6 above, the holder of any Security thereafter surrendered for
conversion shall become entitled to receive any shares of capital stock of the
Company other than shares of its Common Stock, thereafter the Conversion Price
of such other shares so receivable upon conversion of any Securities shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to Common Stock
contained in this Article 4.

SECTION 4.9. ADJUSTMENT FOR TAX PURPOSES.

         The Company shall be entitled to make such reductions in the Conversion
Price, in addition to those required by Section 4.6, as it in its discretion
shall determine to be advisable in

                                       39

order that any stock dividends, subdivision of shares, distribution of rights to
purchase stock or securities, or a distribution or securities convertible into
or exchangeable for stock hereafter made by the Company to its stockholders
shall not be taxable.

SECTION 4.10. NOTICE OF ADJUSTMENT.

         Whenever the Conversion Price is adjusted, or Securityholders become
entitled to other securities or due bills, the Company shall promptly mail to
Securityholders a notice of the adjustment and file with the Trustee an
Officers' Certificate briefly stating the facts requiring the adjustment and the
manner of computing it. The certificate shall be conclusive evidence of the
correctness of such adjustment and the Trustee may conclusively assume that,
unless and until such certificate is received by it, no such adjustment is
required.

SECTION 4.11. NOTICE OF CERTAIN TRANSACTIONS.

         In case:

         (a) the Company shall declare a dividend (or any other distribution) on
its Common Stock (other than in cash out of retained earnings); or

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

         (c) of any reclassification of the Common Stock of the Company (other
than a subdivision or combination of its outstanding Common Stock, or a change
in par value, or from par value to no par value, or from no par value to par
value), or of any consolidation or merger to which the Company is a party and
for which approval of any stockholders of the Company is required, or of the
sale or transfer of all or substantially all of the assets of the Company; or

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

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of Securities at its address appearing on the list provided for in
Section 2.5, as promptly as possible but in any event at least ten days prior to
the applicable date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution or
rights, warrants or options, or, if a record is not to be taken, the date as of
which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up is expected to become effective or occur, and the date
as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up. Failure to give such notice, or any
defect therein, shall not affect the legality or validity of such dividend,
distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

SECTION 4.12. EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE ON
              CONVERSION PRIVILEGE.

         If any of the following shall occur, namely: (i) any reclassification
or change of outstanding shares of Common Stock (other than a change in par
value, or from par value to no par value, or from no par value to par value, or
as a result of a subdivision or combination); (ii) any consolidation,
combination or merger to which the Company is a party other than a merger in
which the Company is the continuing corporation and which does not result in any
reclassification of, or change (other than a change in name, or par value, or
from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination) in, outstanding shares of Common Stock;
or (iii) any sale or conveyance of all or substantially all of the assets of the
Company, then the Company, or such successor or purchasing corporation, as the
case may be, shall, as a condition precedent to such reclassification, change,
consolidation, merger, sale or conveyance, execute and deliver to the Trustee a
supplemental indenture providing that the Holder of each Security then
outstanding shall have the right to convert such Security into the kind and
amount of shares of stock and other securities and property (including cash)
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance by a holder of the number of shares of Common Stock deliverable upon
conversion of such Security immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance. Such supplemental indenture shall
provide for adjustments of the Conversion Price which shall be as nearly
equivalent as maybe practicable to the adjustments of the Conversion Price
provided for in this Article 4. If, in the case of any such consolidation,
merger, sale or conveyance, the stock or other securities and property
(including cash) receivable thereupon by a holder of Common Stock includes
shares of stock or other securities and property of a corporation other than the
successor or purchasing corporation, as the case may be, in such consolidation,
merger, sale or conveyance, then such supplemental indenture shall also be
executed by such other corporation and shall contain such additional provisions
to protect the interests of the Holders of the Securities as the Board of
Directors of the Company shall reasonably consider necessary by reason of the
foregoing. The provision of this Section 4.12 shall similarly apply to
successive consolidations, mergers, sales or conveyances. Notwithstanding the
foregoing, a distribution by the Company to all or substantially all holders of
its Common Stock for which an adjustment to the Conversion Price or provision
for conversion of the Securities may be made pursuant to Section 4.6 shall not
be deemed to be a sale or conveyance of all or substantially all of the assets
of the Company for purposes of this Section 4.12.

         In the event the Company shall execute a supplemental indenture
pursuant to this Section 4.12, the Company shall promptly file with the Trustee
an Opinion of Counsel stating that such supplemental indenture is authorized or
permitted by this Indenture and an Officers' Certificate briefly stating the
reasons therefor, the kind or amount of shares of stock or securities or
property (including cash) receivable by Holders of the Securities upon the
conversion of their Securities after any such reclassification, change,
consolidation, merger, sale or conveyance, any adjustment to be made with
respect thereto and that all conditions precedent have been complied with.

SECTION 4.13. TRUSTEE'S DISCLAIMER.

         The Trustee has no duty to determine when an adjustment under this
Article 4 should be made, how it should be made or what such adjustment should
be, but may accept as conclusive evidence of the correctness of any such
adjustment, and shall be protected in relying upon, the Officers' Certificate
with respect thereto which the Company is obligated to file with the Trustee
pursuant to Section 4.10. The Trustee shall not be accountable for and makes no
representation as to the validity or value of any securities or assets issued
upon conversion of Securities, and the Trustee shall not be responsible for the
Company's failure to comply with any provisions of this Article 4. Each
Conversion Agent (other than the Company or an Affiliate of the Company) shall
have the same protection under this Section 4.13 as the Trustee.

         The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 4.12, but may accept as conclusive evidence of the
correctness thereof, and shall be protected in relying upon, the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 4.12.

SECTION 4.14. VOLUNTARY REDUCTION.

         The Company from time to time may reduce the Conversion Price by any
amount for any period of time if the period is at least 20 Trading Days or such
longer period as may be required by law and if the reduction is irrevocable
during the period; provided that the Board of Directors of the Company
determines that such reduction is in the best interests of the Company; and
provided further, that in no event may the Conversion Price be less than the par
value of a share of Common Stock.

                                   ARTICLE 5.

                                  SUBORDINATION

SECTION 5.1. SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS.

         The Company covenants and agrees, and each Holder of Securities by his
acceptance thereof likewise covenants and agrees, that all Securities are
subject to the provisions of this Article 5; and each Person holding any
Security, whether upon original issue or upon transfer or assignment thereof,
accepts and agrees to be bound by such provisions and acknowledges that such
provisions are for the benefit of, and shall be enforceable directly by, the
holders of Senior Indebtedness.

         Each Holder of Securities authorizes and directs the Trustee on such
Holder's behalf to take such action as may be necessary or appropriate, in the
sole discretion of the Trustee, to acknowledge or effectuate the subordination
between the Holders of Securities and the holders of Senior Indebtedness as
provided in this Article and appoints the Trustee as such Holder's
attorney-in-fact for any and all such purposes.

         The payment of the principal of, premium, if any, and interest
(including Contingent Interest and Liquidated Damages, if any) on and any other
payment due pursuant to this

                                       42
<PAGE>

Indenture or any Securities issued hereunder (including, without limitation, the
payment or deposit of the Redemption Price or Repurchase Price pursuant to
Article 3 and any deposit pursuant to Section 6.3) 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 created, incurred,
assumed or guaranteed.

         Each Holder by accepting a Security acknowledges and agrees that the
subordination provision set forth in this Article 5 are, and are intended to be,
an inducement and consideration to each holder of any Senior Indebtedness of the
Company, whether such Senior Indebtedness was created before or after the
issuance of the Securities, to acquire and continue to hold, or to continue to
hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall be
deemed conclusively to have relied upon such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Senior
Indebtedness, and such holder is made an obligee hereunder and may enforce
directly such subordination provisions.

SECTION 5.2. SECURITIES SUBORDINATED TO PRIOR PAYMENT OF ALL SENIOR INDEBTEDNESS
             ON DISSOLUTION, LIQUIDATION, REORGANIZATION, ETC., OF THE COMPANY.

         Upon any payment or distribution of the assets of the Company of any
kind or character, whether in cash, property or securities (including any
collateral at any time securing the Securities), to creditors upon any
dissolution, winding-up, total or partial liquidation, or reorganization of the
Company (whether voluntary or involuntary, or in bankruptcy, insolvency,
reorganization, liquidation, or receivership proceedings, or upon an assignment
for the benefit of creditors, or any marshalling of the assets of the Company,
or upon any similar proceedings), then in such event:

         (a) all Senior Indebtedness (including principal thereof and interest
thereon) shall first be paid in full before any Payment of the Securities (as
defined in Section 5.5) is made;

         (b) any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities (including any collateral at
any time securing the Securities), to which the Holders or the Trustee on behalf
of the Holders would be entitled except for the provisions of this Article 5,
including any such payment or distribution which may be payable or deliverable
by reason of the payment of another debt of the Company being subordinated to
the payment of the Securities, shall be paid or delivered by any debtor,
Custodian or other person making such payment or distribution, directly to the
holders of the Senior Indebtedness or their Representative or Representatives,
or to the trustee or trustees under any indenture pursuant to which any
instruments evidencing any of such Senior Indebtedness may have been issued,
ratably according to the aggregate amounts remaining unpaid on account of the
principal of and interest on the Senior Indebtedness held or represented by
each, for application to payment of all Senior Indebtedness remaining unpaid, to
the extent necessary to pay all Senior Indebtedness in full after giving effect
to any concurrent payment or distribution, or provision therefor, to the holders
of such Senior Indebtedness; and

                                       43
<PAGE>

         (c) in the event that, notwithstanding the foregoing provisions of this
Section 5.2, any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, shall be received by the
Trustee or the Holders before all Senior Indebtedness is paid in full, such
payment or distribution (subject to the provisions of Sections 5.6 and 5.7)
shall be held in trust for the benefit of, and shall be immediately paid or
delivered by the Trustee or such Holders, as the case may be, to the holders of
Senior Indebtedness remaining unpaid, or their Representative or
Representatives, ratably according to the aggregate amounts remaining unpaid on
account of the principal of and interest on the Senior Indebtedness held or
represented by each, for application to the payment of all Senior Indebtedness
remaining unpaid, to the extent necessary to pay all Senior Indebtedness in full
after giving effect to any concurrent payment or distribution, or provision
therefor, to or for the holders of such Senior Indebtedness.

         The Company shall give prompt notice to the Trustee of any dissolution,
winding-up, liquidation or reorganization of the Company.

         Upon any prepayment, payment or distribution of assets of the Company
referred to in this Article 5, the Trustee, subject to the provisions of
Sections 9.1 and 9.2, and the Holders shall be entitled to conclusively rely
upon any order or decree by any court of competent jurisdiction in which such
dissolution, winding-up, liquidation or reorganization proceeding is pending, or
a certificate of the liquidating trustee or agent or other person making any
distribution to the Trustee or to the Holders, for the purpose of ascertaining
the persons entitled to participate in such distribution, the holders of the
Senior Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article 5; provided that the foregoing shall
apply only if such court, trustee, liquidating trustee or other person has been
fully apprised of the provisions of this Article.

SECTION 5.3. SECURITYHOLDERS TO BE SUBROGATED TO RIGHT OF HOLDERS OF SENIOR
             INDEBTEDNESS.

         Subject to the prior payment in full of all Senior Indebtedness, the
Holders shall be subrogated (equally and ratably with the holders of all
indebtedness of the Company which by its express terms is subordinated to
indebtedness of the Company to substantially the same extent as the Securities
are subordinated and is entitled to like rights of subrogation including but not
limited to holders of the Existing Convertible Notes) to the rights of the
holders of Senior Indebtedness to receive payments or distributions of assets of
the Company applicable to the Senior Indebtedness until the principal of and
interest on the Securities shall be paid in full, and for purposes of such
subrogation, no payments or distributions to the holders of Senior Indebtedness
of assets, whether in cash, property or securities, distributable to the holders
of Senior Indebtedness under the provisions hereof to which the Holders would be
entitled except for the provisions of this Article 5, and no payment pursuant to
the provisions of this Article 5 to the holders of Senior Indebtedness by the
Holders shall, as among the Company, its creditors other than the holders of
Senior Indebtedness, and the Holders, be deemed to be a payment by the Company
to or on account of Senior Indebtedness, it being understood that the provisions
of this Article 5 are, and are intended, solely for the purpose of defining the
relative rights of the Holders, on the one hand, and the holders of Senior
Indebtedness, on the other hand.

SECTION 5.4. OBLIGATIONS OF THE COMPANY UNCONDITIONAL.

         Nothing contained in this Article 5 or elsewhere in this Indenture or
in any Security is intended to or shall impair the obligation of the Company,
which is absolute and unconditional, to pay to the Holders the principal of and
interest on the Securities, as and when the same shall become due and payable in
accordance with the terms of the Securities, or to affect the relative rights of
the Holders and other creditors of the Company other than the holders of Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or any
Holder from exercising all remedies otherwise permitted by applicable law upon
the happening of an Event of Default under this Indenture, subject to the
provisions of Article 8, and the rights, if any, under this Article 5 of the
holders of Senior Indebtedness in respect of assets, whether in cash, property
or securities, of the Company received upon the exercise of any such remedy.

SECTION 5.5. COMPANY NOT TO MAKE PAYMENT WITH RESPECT TO SECURITIES IN CERTAIN
             CIRCUMSTANCES.

         Upon the occurrence of a Payment Default, unless and until the amount
of Senior Indebtedness affected by such Payment Default then due shall have been
paid in full, or such default shall have been cured or waived or shall have
ceased to exist, the Company shall not pay principal of, premium, if any, or
interest on the Securities or any other amount due pursuant to this Indenture or
any Securities or make any deposit pursuant to Article 3 or Section 6.3 or 10.1
and shall not repurchase, redeem or otherwise retire any Securities
(collectively, "Payment of the Securities").

         Unless Section 5.2 shall be applicable, upon (1) the occurrence of a
default on Designated Senior Indebtedness (other than a Payment Default) that
occurs and is continuing that permits the holders of such Designated Senior
Indebtedness (or their Representative or Representatives) to accelerate its
maturity and (2) receipt by the Company and the Trustee from the Senior Agent of
written notice of such occurrence and the imposition of a Payment Blockage
Period hereunder, then the Company shall not make any Payment of the Securities
for a period (the "Payment Blockage Period") commencing on the earlier of the
date of receipt by the Company or the Trustee of such notice from the Senior
Agent and ending on the earlier of (subject to any blockage of payments that may
then be in effect under this Section 5.5) (x) the date 179 days after such date,
(y) the date such default shall have been cured or waived in writing or shall
have ceased to exist or such Senior Indebtedness shall have been discharged, or
(z) the date such Payment Blockage Period shall have been terminated by written
notice to the Company or the Trustee from the Senior Agent, after which, in case
of clause (x), (y) or (z), as the case may be, the Company shall resume making
any and all required payments. Notwithstanding any other provision of this
Indenture, only one Payment Blockage Period may be commenced within any
consecutive 365-day period, and no event of default with respect to any
Designated Senior Indebtedness which existed or was continuing on the date of
the commencement of any Payment Blockage Period with respect to such Designated
Senior Indebtedness shall be, or can be made, the basis for the commencement of
a second Payment Blockage Period whether or not within a period of 365
consecutive days unless such event of default shall have been cured or waived
for a period of not less than 90 consecutive days. In no event will a Payment
Blockage Period extend beyond 179 days.

                                       45
<PAGE>

         In the event that, notwithstanding the foregoing provisions of this
Section 5.5, any Payment of the Securities shall be made by or on behalf of the
Company and received by the Trustee, any Holder or any Paying Agent (or, if the
Company is acting as its own Paying Agent, money for any such payment shall be
segregated and held in trust), which payment was prohibited by this Section 5.5,
then, unless and until the amount of Senior Indebtedness then due, as to which a
default shall have occurred, shall have been paid in full, or such default shall
have been cured or waived, such payment (subject, in each case, to the
provisions of Sections 5.6 and 5.7) shall be held in trust for the benefit of,
and shall be immediately paid over to, the holders of Senior Indebtedness or
their Representative or Representatives, ratably according to the aggregate
amounts remaining unpaid on account of the principal of and interest on the
Senior Indebtedness held or represented by each, for application to the payment
of all Senior Indebtedness remaining unpaid to the extent necessary to pay all
Senior Indebtedness in accordance with its terms, after giving effect to any
concurrent payment or distribution to or for the benefit of the holders of
Senior Indebtedness. The Company shall give prompt written notice to the Trustee
of any default under any Senior Indebtedness or under any agreement pursuant to
which Senior Indebtedness may have been issued.

SECTION 5.6. NOTICE TO TRUSTEE.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities, but failure to give such notice shall not
affect the subordination provided in this Article 5 of the Securities to Senior
Indebtedness. Notwithstanding the provisions of this Article 5 or any other
provision of this Indenture, the Trustee shall not at any time be charged with
knowledge of the existence of any facts which would prohibit the making of any
payment to or by the Trustee, unless and until the Trustee shall have received
written notice thereof from the Company or from the holder or holders of Senior
Indebtedness or from their Representative or Representatives; and, prior to the
receipt of any such notice, the Trustee, subject to the provisions of Sections
9.1 and 9.2, shall be entitled to assume conclusively that no such facts exist.

         The Trustee shall be entitled to conclusively rely on the delivery to
it of a written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a Representative of such holder) to establish that such notice
has been given by a holder of Senior Indebtedness or a Representative of any
such holder. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article 5, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
each Person under this Article 5, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

SECTION 5.7. APPLICATION BY TRUSTEE OF MONIES DEPOSITED WITH IT.

         Money or U.S. Government Obligations deposited in trust with the
Trustee pursuant to Sections 6.3 and 10.1 and not in violation of this Article 5
shall be for the sole benefit of

                                       46
<PAGE>

Securityholders and shall thereafter not be subject to the subordination
provisions of this Article 5. Otherwise, any deposit of monies by the Company
with the Trustee or any Paying Agent (whether or not in trust) for the payment
of the principal of or interest on any Securities shall be subject to the
provisions of Sections 5.1, 5.2, 5.3 and 5.5; except that, if at least three
Business Days prior to the date on which by the terms of this Indenture any such
monies may become payable for any purpose (including, without limitation, the
payment of either the principal of or interest on any Security), a Trust Officer
of the Trustee shall not have received with respect to such monies the notice
provided for in Section 5.6, then the Trustee or any Paying Agent shall have
full power and authority to receive such monies and to apply such monies to the
purpose for which they were received, and shall not be affected by any notice to
the contrary which may be received by it within three Business Days prior to or
after such date. This Section 5.7 shall be construed solely for the benefit of
the Trustee and the Paying Agent and shall not otherwise affect the rights that
holders of Senior Indebtedness may have to recover any such payments from the
Holders in accordance with the provisions of this Article 5.

SECTION 5.8. SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS OF THE
             COMPANY OR HOLDERS OF SENIOR INDEBTEDNESS.

         No right of any present or future holders 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 which any such holder may have or
be otherwise charged with. The holders of any Senior Indebtedness may extend,
renew, modify or amend the terms of such Senior Indebtedness or any security
therefor and release, sell or exchange such security and otherwise deal freely
with the Company, all without affecting the liabilities and obligations of the
parties to this Indenture or the Holders. No amendment of this Article 5 or any
defined terms used herein or any other Sections referred to in this Article 5
which adversely affects the rights hereunder of holders of Senior Indebtedness,
shall be effective unless the holders of such Senior Indebtedness (required
pursuant to the terms of such Senior Indebtedness to give such consent) have
consented thereto.

SECTION 5.9. TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each Holder of a Security by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to acknowledge and effectuate the subordination provided in this
Article 5 and appoints the Trustee his attorney-in-fact for any and all such
purposes.

SECTION 5.10. RIGHT OF TRUSTEE TO HOLD SENIOR INDEBTEDNESS.

         The Trustee, in its individual capacity, shall be entitled to all of
the rights set forth in this Article 5 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 this Indenture shall be construed to deprive the
Trustee of any of its rights as such holder. Nothing in this Article 5 shall
apply to claims of, or payments to, the Trustee under or pursuant to Section
9.7.

                                       47
<PAGE>

SECTION 5.11. ARTICLE 5 NOT TO PREVENT EVENTS OF DEFAULT.

         The failure to make a Payment of the Securities by reason of any
provision in this Article 5 shall not be construed as preventing the occurrence
of an Event of Default under Section 8.1.

SECTION 5.12. NO FIDUCIARY DUTY CREATED TO HOLDERS OF SENIOR INDEBTEDNESS.

         Notwithstanding any other provision in this Article 5, the Trustee
shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness by virtue of the provisions of this Article 5 or otherwise. With
respect to the holders of Senior Indebtedness, the Trustee undertakes to perform
or to observe only such of its covenants or obligations as are specifically set
forth in this Article 5 and no implied covenants or obligations with respect to
holders of Senior Indebtedness shall be read into this Indenture against the
Trustee.

SECTION 5.13. ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article 5 shall in such case (unless the context shall otherwise
require) be construed as extending to and including such Paying Agent within its
meaning as fully for all intents and purposes as if such Paying Agent were named
in this Article 5 in addition to or in place of the Trustee; provided, however,
that Sections 5.6, 5.10 and 5.12 shall not apply to the Company if it acts as
Paying Agent.

SECTION 5.14. CERTAIN CONVERSION DEEMED PAYMENT.

         For the purposes of this Article 5 only, (1) the issuance and delivery
of junior securities upon conversion of Securities in accordance with Article 4
shall not be deemed to constitute a payment or distribution on account of the
principal of or premium or interest on Securities or on account of the purchase
or other acquisition of Securities, and (2) the payment, issuance or delivery of
cash, property or securities (other than junior securities) upon conversion of a
Security shall be deemed to constitute payment on account of principal of such
Security. For the purposes of this Section, the term "junior securities" means
(a) shares of any stock of any class of the Company and (b) securities of the
Company which are subordinated in right of payment to all Senior Indebtedness
which may be outstanding at the time of issuance or delivery of such securities
to substantially the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall impair, as among the Company, its creditors other than holders of Senior
Indebtedness and the Holders of the Securities, the right, which is absolute and
unconditional, of the Holder of any Security to convert such Security in
accordance with Article 4.

SECTION 5.15. CONTRACTUAL SUBORDINATION.

         This Article 5 represents a bona fide agreement of contractual
subordination pursuant to Section 510(b) of the Title 11, U.S. Code.

         The Company covenants and agrees that it will duly and punctually pay
or cause to be paid the principal amount at maturity, Redemption Price,
Repurchase Price, Change in Control Repurchase Price, and interest (including
Contingent Interest and Liquidated Damages, if any), in respect of each of the
Securities at the places, at the respective times and in the manner provided
herein and in the Securities. Each installment of interest on the Securities may
be paid by mailing checks for the interest payable to or upon the written order
of the Holders of Securities entitled thereto as they shall appear on the
registry books of the Company; provided that with respect to any Holder of
Securities with an aggregate principal amount equal to or in excess of $5
million, at the request of such Holder in writing the Company shall pay interest
on such Holder's Securities by wire transfer in immediately available funds to
an account in the continental United States.

SECTION 6.2. SEC REPORTS; 144A INFORMATION.

         The Company shall file all reports and other information and documents
which it is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act, and within 15 days after it files them with the SEC, the Company
shall file copies of all such reports, information and other documents with the
Trustee. The Company will cause any quarterly and annual reports which it mails
to its stockholders to be mailed to the Holders of the Securities.

         In the event the Company is at any time no longer subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company
will prepare, for the first three quarters of each fiscal year, quarterly
financial statements substantially equivalent to the financial statements
required to be included in a report on Form 10-Q under the Exchange Act and the
Company will also prepare, on an annual basis, complete audited consolidated
financial statements including, but not limited to, a balance sheet, a statement
of income and retained earnings, a statement of cash flows and all appropriate
notes. All such financial statements will be prepared in accordance with
generally accepted accounting principles consistently applied, except for
changes with which the Company's independent accountants concur, and except that
quarterly statements may be subject to year-end adjustments. The Company will
cause a copy of such financial statements to be filed with the Trustee and
mailed to the Holders of the Securities within 60 days after the close for each
of the first three quarters of each fiscal year and within 105 days after the
close of each fiscal year. The Company will also comply with the other
provisions of TIA 314(a).

         Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

                                       49
<PAGE>

         At any time when the Company is not subject to Section 13 or 15(d) of
the Exchange Act, nor exempt from reporting pursuant to 12g3-2(b) under the
Exchange Act, upon the request of a Holder or beneficial owner of a Security,
the Company will promptly furnish or cause to be furnished Rule 144A Information
(as defined below) to such Holder, to such beneficial owner or to prospective
purchaser designated by such Securityholder or beneficial owner, as the case may
be, in order to permit compliance by such Securityholder or beneficial owner
with Rule 144A under the Securities Act in connection with the resale of such
Security by such Securityholder or beneficial owner; provided, however, the
Company shall not be required to furnish such information in connection with any
request made on or after the date which is two years from the later of (i) the
date such Security (or any predecessor Security) was acquired from the Company
or (ii) the date such Security (or any predecessor Security) was last acquired
from an "affiliate" of the Company within the meaning of Rule 144 under the
Securities Act. "Rule 144A Information" shall be such information as is
specified pursuant to Rule 144A(d)(4) under the Securities Act (or any successor
provision thereto).

SECTION 6.3. LIQUIDATION.

         Subject to the provisions of Article 5, insofar as they may be
applicable hereto, the Board of Directors or the stockholders of the Company may
not adopt a plan of liquidation which plan provides for, contemplates, or the
effectuation of which is preceded by (a) the sale, lease, conveyance or other
disposition of all or substantially all of the assets of the Company otherwise
than substantially as an entirety (Article 7 being the Article which governs any
such sale, lease, conveyance or other disposition substantially as an entirety),
and (b) the distribution of all or substantially all of the proceeds of such
sale, lease, conveyance or other disposition and of the remaining assets of the
Company to the holders of the capital stock of the Company, unless the Company
shall in connection with the adoption of such plan make provision for, or agree
that prior to making any liquidating distributions to the holders of capital
stock of the Company it will make provision for, the satisfaction of the
Company's obligations hereunder and under the Securities as to the payment of
principal and interest. The Company shall be deemed to have made provision for
such payments only if (1) the Company irrevocably deposits in trust with the
Trustee money or U.S. Government Obligations maturing as to principal and
interest in such amounts and at such times as are sufficient, without
consideration of any reinvestment of such interest, to pay the principal of and
interest on the Securities then outstanding to maturity and to pay all other
sums payable by it hereunder, or (2) there is an express assumption of the due
and punctual payment of the Company's obligations hereunder and under the
Securities and the performance and observance of all covenants and conditions to
be performed by the Company hereunder, by the execution and delivery of a
supplemental indenture in form reasonably satisfactory to the Trustee by a
person who acquires, or will acquire (otherwise than pursuant to a lease) a
portion of the assets of the Company, and which person will have Consolidated
Net Worth (immediately after the acquisition) equal to not less than the
Consolidated Net Worth of the Company (immediately preceding such acquisition),
and which is a corporation organized under the laws of the United States, any
State thereof or the District of Columbia; provided, however, that the Company
shall not make any liquidating distribution to the holders of capital stock of
the Company described in the first sentence of this Section 6.3 until after the
Company shall have certified to the Trustee with an Officers' Certificate at
least five days prior to the making of any liquidating distribution that it has
complied with the provisions of this Section 6.3.

                                       50
<PAGE>
SECTION 6.4. COMPLIANCE CERTIFICATES.

         The Company shall deliver to the Trustee within 120 days after the end
of each fiscal year of the Company, an Officers' Certificate as to the signer's
knowledge of the Company's compliance with all conditions and covenants on its
part contained in this Indenture and stating whether or not the signer knows of
any default or Event of Default. If such signer knows of such a default or Event
of Default, the Certificate shall describe the default or Event of Default and
the efforts to remedy the same. For the purposes of this Section 6.4, compliance
shall be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture. The Certificate need not
comply with Section 12.4.

SECTION 6.5. NOTICE OF DEFAULTS.

         The Company will give notice to the Trustee, promptly, and in any event
within five days, upon becoming aware thereof, of the existence of any Event of
Default or an event which, with notice or the lapse of time or both would
constitute an Event of Default hereunder.

SECTION 6.6. PAYMENT OF TAXES AND OTHER CLAIMS.

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

SECTION 6.7. CORPORATE EXISTENCE.

         Subject to Section 6.3 and Article 7, the Company will do or cause to
be done all things necessary to preserve and keep in full force and effect its
corporate existence and rights (charter and statutory); provided, however, that
the Company shall not be required to preserve any right if the Company shall
determine that the preservation is no longer desirable in the conduct of the
Company's business and that the loss thereof is not, and will not be, adverse in
any material respect to the Holders.

SECTION 6.8. MAINTENANCE OF PROPERTIES.

         Subject to Section 6.3, the Company will cause all material properties
owned, leased or licensed in the conduct of its business to be maintained and
kept in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof and thereto, all as in the
judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times
while any Securities are outstanding; provided, however, that nothing in this
Section 6.8 shall prevent the Company from

                                       51
<PAGE>

doing otherwise if, in the judgment of the Company, the same is desirable in the
conduct of the Company's business and is not, and will not be, adverse in any
material respect to the Holders.

SECTION 6.9. FURTHER INSTRUMENTS AND ACTS.

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

SECTION 6.10. MAINTENANCE OF OFFICE OR AGENCY.

         The Company will maintain in The City of New York an office or agency
where Securities may be presented or surrendered for payment or repurchase,
where Securities may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served. The office of the agent of the Trustee in The
City of New York shall be such office or agency of the Company, unless the
Company shall designate and maintain some other office or agency for one or more
of such purposes. The Company will give prompt written notice to the Trustee of
any change in the location of any such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

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

SECTION 6.11. RESALE OF CERTAIN SECURITIES; REPORTING ISSUER.

         During the period beginning on the last date of original issuance of
the Securities and ending on the date that is two years from such date, the
Company will not, and will use all reasonable efforts not to permit any of its
"affiliates" (as defined under Rule 144 under the Securities Act or any
successor provision thereto) to, resell (x) any Securities which constitute
"restricted securities" under Rule 144 or (y) any securities into which the
Securities have been converted under this Indenture which constitute "restricted
securities" under Rule 144, that in either case have been reacquired by any of
them, except pursuant to an effective registration statement under the
Securities Act. The Trustee shall have no responsibility in respect of the
Company's performance of its agreement in the preceding sentence.

SECTION 6.12. REGISTRATION RIGHTS.

         (a) The Company agrees that the Holders (and any Person that has
beneficial interest of a Security) from time to time of Registrable Securities
(as such term is defined in the

                                       52
<PAGE>

Registration Rights Agreement) are entitled to the benefits of the Registration
Rights Agreement. Pursuant to the Registration Rights Agreement, the Company has
agreed for the benefit of the Holders from time to time of Registrable
Securities, at the Company's expense, (i) to file within 90 days after the last
date of original issuance of the Securities, a registration statement (the
"Registration Statement") with the Commission with respect to resales of the
Restricted Securities, (ii) to use all reasonable best efforts to cause such
Registration Statement to be declared effective by the Commission not later than
180 days after the last date of original issuance of the Securities, and (iii)
to use all reasonable best efforts to maintain such Registration Statement
continuously effective under the Securities Act subject to and in accordance
with the terms of the Registration Rights Agreement.

         Liquidated Damages (the "Liquidated Damages") with respect to the
Securities shall be assessed if a Registration Default (as defined in the
Registration Rights Agreement) occurs. Liquidated Damages shall accrue on the
Securities over and above the interest set forth in the title of the Securities
from and including the date on which any such Registration Default shall occur,
to but excluding the date on which such Registration Default has been cured (in
the manner described in the Registration Rights Agreement), at a rate of 0.50%
per annum.

         (b) Any amounts of Liquidated Damages due pursuant to clause (a) of
this Section 6.12 shall be payable in cash on the regular interest Payment
Dates. The amount of Liquidated Damages shall be determined by multiplying the
applicable Liquidated Damages rate by the principal amount of the Securities,
multiplied by a fraction, the numerator of such period (determined on the basis
of a 360-day year comprised of twelve 30-day months), and the denominator of
which is 360.

         Whenever in this Indenture there is mentioned, in any context, the
payment of the principal of, premium, if any, or interest on, or in respect of,
any Security, such mention shall be deemed to include mention of the payment of
Liquidated Damages provided for in this Section to the extent that, in such
context, Liquidated Damages are, were or would be payable in respect thereof
pursuant to the provisions of this Section 6.12 and express mention of the
payment of Liquidated Damages (if applicable) in any provisions hereof shall not
be construed as excluding Liquidated Damages in those provisions hereof where
such express mention is not made. A default by the Company under the
Registration Rights Agreement, other than a default in the payment of Liquidated
Damages, shall not be treated as a Default under this Indenture.

SECTION 6.13. LIQUIDATED DAMAGES.

         If Liquidated Damages is payable pursuant to the Registration Rights
Agreement, the Company shall deliver to the Trustee a certificate to that effect
stating (i) the amount of such Liquidated Damages that is payable and (ii) the
date on which such Liquidated Damages is payable. Unless and until a Trust
Officer receives at the Corporate Trust Office such a certificate, the Trustee
may assume without inquiry that no such Liquidated Damages is payable. If the
Company has paid Liquidated Damages directly to the Persons entitled to it, the
Company shall deliver to the Trustee a certificate setting forth the particulars
of such payment.

                                       53
<PAGE>

SECTION 6.14. STAY, EXTENSION AND USURY LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not, by resort to any such law, hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law had been
enacted.

SECTION 6.15. TAX TREATMENT OF SECURITIES

         The Company and the Holders, by purchasing the Securities, agree that
(i) the Securities are contingent payment debt instruments as defined in
Treasury Regulations Section 1.1275-4(b), (ii) each Holder shall be bound by the
Company's application of the Treasury Regulations to the Securities, including
the Company's determination that the rate at which interest will be deemed to
accrue on the Securities for United States federal income tax purposes will be
9.12% per annum compounded semi-annually, which is the rate comparable to the
rate at which the Company would borrow on a noncontingent, nonconvertible basis
with terms and conditions otherwise comparable to the Securities, (iii) each
Holder shall use the projected payment schedule with respect to the Securities
determined by the Company, as required by Treasury Regulations Section
1.1275-4(b)(4)(iv), to determine its interest accruals and adjustments as
provided in Treasury Regulations Section 1.1275-4(b), and (iv) the Company and
each Holder will not take any position on a tax return inconsistent with (i),
(ii), or (iii), unless required by applicable law.

                              SUCCESSOR CORPORATION

SECTION 7.1. WHEN COMPANY MAY MERGE, ETC.

         The Company shall not consolidate with or merge into any other Person,
or convey, transfer or lease its properties and assets substantially as an
entirety to any Person, and shall not permit any Person (other than a Subsidiary
wholly-owned by the Company) to consolidate with or merge into the Company or
convey, transfer or lease its properties and assets substantially as an entirety
to the Company, unless:

         (a) in case the Company shall consolidate with or merge into another
Person or convey, or transfer or lease its properties and assets substantially
as an entirety to any Person, the Person formed by such consolidation or into
which the Company is merged or the Person which acquires by conveyance or
transfer, or which leases, the properties and assets of the Company
substantially as an entirety shall be a corporation, partnership or trust, shall
be organized and validly existing under the laws of the United States of
America, any State thereof or the District of Columbia and shall expressly
assume, by an indenture supplemental thereto, executed and delivered to the
Trustee, in form satisfactory to the Trustee, the due and punctual payment of
the

                                       54
<PAGE>

principal of (and premium, if any) and interest on all the Securities and the
performance or observance of every covenant of this Indenture on the part of the
Company to be performed or observed and shall have provided for conversion
rights in accordance with Section 4.12;

         (b) immediately after giving effect to such transaction, no Event of
Default, and no event which, after notice or lapse of time or both, would become
an Event of Default, shall have occurred and be continuing; and

         (c) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that such consolidation, merger,
conveyance, transfer or lease and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture comply with this
Article and that all conditions precedent herein provided for relating to such
transaction have been complied with.

SECTION 7.2. SUCCESSOR CORPORATION SUBSTITUTED.

         Upon any consolidation of the Company with, or merger of the Company
into, any other Person or any conveyance, transfer or lease of the properties
and assets of the Company substantially as an entirety in accordance with
Section 7.1, the successor Person formed by such consolidation or into which the
Company is merged or to which such conveyance, transfer or lease 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
Person had been named as the Company herein, and thereafter, except in the case
of a lease, the predecessor Person shall be relieved of all obligations and
covenants under this Indenture and the Securities.

                                   ARTICLE 8.

                              DEFAULT AND REMEDIES

SECTION 8.1. EVENTS OF DEFAULT.

         An "Event of Default" occurs if:

         (1) the Company defaults in the payment of any interest (including
Contingent Interest and Liquidated Damages, if any) upon any of the Securities
when due and payable and the default continues for a period of 30 days whether
or not such payment is prevented by Article 5;

         (2) the Company defaults in the payment of the principal of and
premium, if any, on any of the Securities when due, including on a redemption
date, whether or not such payment is prevented by Article 5;

         (3) the Company fails to pay when due the principal of or interest on
indebtedness for money borrowed by the Company or its Subsidiaries in excess of
$10 million, beyond the grace period, if any, provided in the instrument or
agreement under which the indebtedness was created, or the acceleration of that
indebtedness that is not withdrawn within 30 days after the date of written
notice to the Company by the Trustee or to the Company and the Trustee by the
Holders of at least 25% in principal amount of the outstanding Securities;

                                       55
<PAGE>

         (4) the Company fails to deliver shares of Common Stock within 15 days
after such Common Stock is required to be delivered upon conversion of a
Security as provided in this Indenture;

         (5) a default by the Company in the performance, or breach, of any of
the Company's other covenants in this Indenture which are not remedied by the
end of a period of 60 days after written notice to the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
outstanding Securities;

         (6) the Company or any Significant Subsidiary pursuant to or within the
meaning of any Bankruptcy Law:

                  A. commences a voluntary case or proceeding;

                  B. consents to the entry of an order for relief against it in
         an involuntary case or proceeding;

                  C. consents to the appointment of a Custodian of it or for all
         or substantially all of its assets;

                  D. makes a general assignment for the benefit of its
         creditors; or

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

                  A. is for relief against the Company or any Significant
         Subsidiary in an involuntary case or proceeding;

                  B. appoints a Custodian of the Company or any Significant
         Subsidiary or for all or substantially all of the assets of any of
         them; or

                  C. orders the liquidation of the Company or any Significant
         Subsidiary;

         and in each case the order or decree remains unstated and in effect for
         60 days.

         The term "Bankruptcy Law" means Title 11, U.S. Code or any similar
foreign, Federal or state law for the relief of debtors. For purposes of this
Section 8.1, the term "Custodian" means any receiver, trustee, assignee,
liquidator, sequestrator or similar official under any Bankruptcy Law.

         A default under clause (5) is not an Event of Default until the Trustee
notifies the Company or the Holders of at least 25% in principal amount of the
Securities then outstanding notify the Company and the Trustee, of the default,
and the Company does not cure the default within 30 days after receipt of such
notice. The notice given pursuant to this Section 8.1 must specify the default,
demand that it be remedied and state that the notice is a "Notice of Default."
When a default is cured, it ceases.

                                       56
<PAGE>

         Subject to the provisions of Sections 9.1 and 9.2, the Trustee shall
not be charged with knowledge of any Event of Default unless written notice
thereof shall have been given to a Trust Officer at the Corporate Trust Office
of the Trustee by the Company, the Paying Agent, any Holder or an agent of any
Holder. Within 90 days after a default, the Trustee must give to the registered
Holders of Securities notice of all uncured defaults known to it.

SECTION 8.2. ACCELERATION.

         If an Event of Default (other than an Event of Default specified in
Section 8.1(6) or (7)) occurs and is continuing, the Trustee may, by notice to
the Company, or the Holders of at least 25% in principal amount of the
Securities then outstanding may, by notice to the Company and the Trustee, and
the Trustee shall, upon the request of such Holders, declare all unpaid
principal of and accrued interest (including Contingent Interest and Liquidated
Damages, if any) to the date of acceleration on the Securities then outstanding
(if not then due and payable) to be due and payable upon any such declaration,
and the same shall become and be immediately due and payable. If an Event of
Default specified in Section 8.1(6) or (7) occurs, all unpaid principal of and
accrued interest (including Contingent Interest and Liquidated Damages, if any)
on the Securities then outstanding shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Securityholder.

         The Holders of a majority in aggregate principal amount of the
Securities then outstanding by notice to the Trustee may, on behalf of all
Holders, rescind an acceleration and its consequences if (i) all existing Events
of Default, other than the nonpayment of the principal of and accrued interest
(including Contingent Interest and Liquidated Damages, if any) on the Securities
which has become due solely by such declaration of acceleration, have been cured
or waived; (ii) the Company has paid or deposited with the Trustee a sum
sufficient to pay (a) all overdue interest on the Securities, (b) the principal
of any Security which has become due otherwise then by such declaration of
acceleration, and (c) to the extent the payment of such interest is lawful,
interest on overdue installments of interest and overdue principal, which has
become due otherwise than by such declaration of acceleration; (iii) the
rescission would not conflict with any judgment or decree of a court of
competent jurisdiction; and (iv) all payments due to the Trustee and any
predecessor Trustee under Section 9.7 have been made. No such rescission shall
affect any subsequent default or impair any right consequent thereon. Anything
herein contained to the contrary notwithstanding, in the event of any
acceleration pursuant to this Section 8.2, the Company shall not be obligated to
pay any premium which it would have had to pay if it had then elected to redeem
the Securities pursuant to paragraph 5 of the Securities, except in the case of
any Event of Default occurring by reason of any willful action (or inaction)
taken (or not taken) by or on behalf of the Company with the intention of
avoiding payment of the premium which it would have had to pay if it had then
elected to redeem the Securities pursuant to paragraph 5 of the form of Security
attached hereto as Exhibit A, in which case an equivalent premium shall also
become and be immediately due and payable to the extent permitted by law.

SECTION 8.3. OTHER REMEDIES.

         In case of an Event of Default hereunder, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial

                                       57
<PAGE>

proceedings as the Trustee shall deem most effectual to protect and enforce any
of such rights, either by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

         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 Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.

SECTION 8.4. WAIVER OF DEFAULTS AND EVENTS OF DEFAULT.

         Subject to Section 8.7, the Holders of a majority in aggregate
principal amount of the Securities then outstanding by notice to the Trustee
may, on behalf of all Holders, waive an existing default or Event of Default and
its consequences, except a default in the payment of the principal of (or
premium, if any) or interest (including Contingent Interest and Liquidated
Damages, if any) on any Security as specified in clauses (1) and (2) of Section
8.1, or a default in respect of a covenant or provision hereof which cannot be
modified or amended pursuant to Section 11.2 without the consent of the Holder
of each Security affected thereby. When a default or Event of Default is waived,
it is cured and ceases.

SECTION 8.5. CONTROL BY MAJORITY.

         The Holders of a majority in principal amount of the Securities then
outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture; provided that the Trustee may take any
other action deemed proper by the Trustee which is not inconsistent with such
direction.

SECTION 8.6. LIMITATION ON SUITS.

         A Securityholder may not pursue any remedy with respect to this
Indenture or the Securities (except actions for payment of overdue principal or
interest (including Contingent Interest and Liquidated Damages, if any) or for
the conversion of the Securities pursuant to Article 4) unless:

         (1) the Holder gives to the Trustee written notice of a continuing
Event of Default;

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

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

                                       58
<PAGE>

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

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

         A Securityholder may not use any provision of this Indenture to
prejudice the rights of another Securityholder or to obtain a preference or
priority over such other Securityholder, or to enforce any rights under this
Indenture other than in the manner herein provided and for the equal and ratable
benefit of all the Securityholders.

SECTION 8.7. RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture (but subject to
Article 5), the right of any Holder of a Security to receive payment of
principal of (and premium, if any) and interest on the Security, on or after the
respective dates on which such payments are due as expressed in the Security, or
to convert the Security, or to bring suit for the enforcement of any such
payment on or after such respective dates, is absolute and unconditional and
shall not be impaired or affected without the consent of the Holder.

SECTION 8.8. COLLECTION SUIT BY TRUSTEE.

         If an Event of Default in the payment of principal or interest
specified in Section 8.1(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or another obligor on the Securities for the whole amount of principal
and accrued interest remaining unpaid, together with interest on overdue
principal and, to the extent that payment of such interest is lawful, interest
on overdue installments of interest, in each case at the rate per annum borne by
the Securities and such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

SECTION 8.9. TRUSTEE MAY FILE PROOFS OF CLAIM.

         The Trustee may file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel) and the Securityholders
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
and empowered to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same, and any Custodian in
any such judicial proceeding is hereby authorized by each Securityholder 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 Securityholders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 9.7, and to the extent that such payment
of the reasonable compensation, expenses, disbursements and advances in any such
proceedings shall be denied

                                       59
<PAGE>

for any reason, payment of the same shall be secured by a lien on, and shall be
paid out of, any and all distributions, dividends, monies, securities and other
property which the Securityholders may be entitled to receive in such
proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or the Trustee to authorize or accept or
adopt on behalf of any Securityholder 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
Securityholder in any such proceeding.

SECTION 8.10. PRIORITIES.

         Subject to Article 5, if the Trustee collects any money pursuant to
this Article 8, it shall pay out the money in the following order:

         First, to the Trustee for amounts due under Section 9.7;

         Second, to Securityholders for amounts due and unpaid on the Securities
for principal and interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Securities for principal and
interest, respectively; and

         Third, to the Company.

         The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 8.10. At least 15 days before such
record date, the Trustee shall mail to each Securityholder and the Company a
notice that states the Record Date, the Payment Date and the amount to be paid.

SECTION 8.11. UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 8.11 does not apply to a suit made by the Trustee, a suit by a
Holder pursuant to Section 8.7, or a suit by any Holder, or group of Holders, of
more than 10% in principal amount of the Securities then outstanding. This
Section 8.11 shall be in lieu of Section 315(c) of the TIA and such Section
315(c) is hereby expressly excluded from this Indenture as permitted by the TIA.

SECTION 8.12. RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Securityholder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Securityholder, then and in every such case, subject to
any determination in such proceeding, the Company, the Trustee and the
Securityholders shall be restored severally and respectively to their former
positions

                                       60
<PAGE>

hereunder and thereafter all rights and remedies of the Trustee and the
Securityholders shall continue as though no such proceeding had been instituted.

SECTION 8.13. RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 2.7, no right or remedy herein conferred upon or reserved to the Trustee
or to the Securityholders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 8.14. DELAY OR OMISSION NOT WAIVER.

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

                                   ARTICLE 9.

                                     TRUSTEE

SECTION 9.1. 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 person
would exercise or use under the circumstances in the conduct of his own affairs.

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

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

         (2) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture. The Trustee,
however, 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).

                                       61
<PAGE>

         (c) The Trustee may not be relieved, and no provision of this Indenture
shall be construed to relieve the Trustee, from liability for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except
that:

         (1) this paragraph does not limit the effect of paragraph (b) of this
Section 9.1;

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

         (3) the Trustee shall not be liable with respect to any action it takes
or omits to take in good faith in accordance with a direction received by it
pursuant to Section 8.5; and

         (4) no provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

         (d) The Trustee may refuse to perform any duty or exercise any right or
power unless it receives indemnity reasonably satisfactory to it against any
loss, liability, expense or fee.

         (e) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 9.1.

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

SECTION 9.2. RIGHTS OF TRUSTEE.

         Subject to Section 9.1:

         (a) The Trustee may conclusively rely on any document believed by it to
be genuine and to have been signed or presented by the proper person. The
Trustee need not investigate any fact or matter stated in the document.

         (b) Whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, it may require an Officers'
Certificate or an Opinion of Counsel, which shall conform to Section 12.4 (b).
The Trustee shall not be liable for any action it takes or omits to take in good
faith in reliance on such Certificate or Opinion.

         (c) The Trustee may act through its agents and shall not be responsible

<PAGE>

respect of any action taken, omitted or suffered by it hereunder in good faith
and in accordance with the advice or opinion of such counsel.

         (e) Any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a written Company request or Officers' Certificate and
any resolution of the Board of Directors may be sufficiently evidenced by a
Board Resolution.

         (f) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney
at the sole cost of the Company and shall incur no liability or additional
liability of any kind by reason of such inquiry or investigation.

         (g) The Trustee shall not be liable for any action taken, suffered, or
omitted to be taken by it in good faith and reasonably believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Indenture.

         (h) 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 which 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 and this Indenture.

         (i) The rights, privileges, protections, immunities and benefits given
to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and to each agent, custodian and other Person employed to act
hereunder.

         (j) The Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of Officers of
the Company authorized at such time to take specified actions pursuant to this
Indenture, which Officers' Certificate may be signed by any person authorized to
sign an Officers' Certificate, including any person specified as so authorized
in any such certificate previously delivered and not superseded.

SECTION 9.3. INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or an
Affiliate of the Company 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 Sections 9.10 and 9.11.

SECTION 9.4. 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

                                       63
<PAGE>

Securities, and it shall not be responsible for the recitals contained herein or
any statement in the Securities other than its certificate of authentication.

SECTION 9.5. NOTICE OF DEFAULT OR EVENTS OF DEFAULT.

         If a default or an Event of Default occurs and is continuing and if it
is actually known to the Trustee, the Trustee shall mail to each Securityholder
notice of the default or Event of Default within 90 days after it occurs. Except
in the case of a default or an Event of Default in payment of the principal of
or interest (including Contingent Interest and Liquidated Damages, if any) on
any 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 interest of Securityholders.

SECTION 9.6. REPORTS BY TRUSTEE TO HOLDERS.

         If such report is required by TIA 313, within 60 days after each May
15, beginning with the May 15 following the date of this Indenture, the Trustee
shall mail to each Securityholder a brief report dated as of such May 15 that
complies with TIA 313(a). The Trustee also shall comply with TIA 313(b)(2) and
(c).

         A copy of each report at the time of its mailing to Securityholders
shall be mailed to the Company and filed with the SEC and each stock exchange,
if any, on which the Securities are listed. The Company shall notify the Trustee
whenever the Securities become listed on or delisted from any stock exchange and
any changes in the stock exchanges on which the Securities are listed.

SECTION 9.7. COMPENSATION AND INDEMNITY.

         The Company shall pay to the Trustee from time to time such
compensation for its services hereunder as the Company and the Trustee shall
from time to time agree in writing (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust). The Company shall reimburse the Trustee upon request for all reasonable
disbursements, expenses and advances incurred or made by it. Such expenses may
include the reasonable compensation, disbursements and expenses of Trustee's
agents and counsel.

         The Company shall indemnify the Trustee or any predecessor Trustee and
their agents for, and hold them harmless against, any loss, liability or expense
incurred by it in connection with its duties under this Indenture or any action
or failure to act as authorized or within the discretion or rights or powers
conferred upon the Trustee hereunder, including the costs and expenses of
defending itself against any claim (whether asserted by the Company, or any
Holder or any other Person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder. The Trustee shall notify
the Company promptly of any claim asserted against the Trustee for which it may
seek indemnity. The Trustee shall have the option of undertaking the defense of
such claims at the Company's expense and may have separate counsel. The
reasonable fees and expenses of such counsel shall be paid by the Company. The
Company need not pay for any settlement without its written consent, which
consent shall not be unreasonably withheld or delayed.

                                       64
<PAGE>

         The Company need not reimburse the Trustee for any expense or indemnify
it against any loss or liability incurred by it through its own negligent
action, negligent failure to act or willful misconduct.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 8.1(6) or (7) occurs, such expenses and the
compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Law.

         The Trustee shall have a lien prior to the Securities as to all
property and funds held by it hereunder for any amount owing it or any
predecessor Trustee pursuant to this Section 9.7, except with respect to funds
held in trust for the benefit of the Holders of particular Securities.

         The provisions of this Section 9.7 shall survive the termination of
this Indenture.

SECTION 9.8. REPLACEMENT OF TRUSTEE.

         The Trustee may resign by so notifying the Company; provided, however,
no such resignation shall be effective until a successor Trustee has accepted
its appointment pursuant to this Section 9.8. The Holders of a majority in
principal amount of the Securities then outstanding may remove the Trustee by so
notifying the Trustee and may appoint a successor Trustee with the Company's
written consent. The Company may remove the Trustee if:

         (1)      the Trustee fails to comply with Section 9.10;

         (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

         (4)      the Trustee becomes incapable of acting as trustee.

         If 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.

         If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee (at the Company's
expense), the Company or the Holders of 10% in principal amount of the
Securities then outstanding may petition any court of competent jurisdiction for
the appointment of a successor Trustee.

         If the Trustee fails to comply with Section 9.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee and be released from its obligations (exclusive of any
liabilities Trustee may have incurred while acting as Trustee) hereunder, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee

                                       65
<PAGE>

shall have all the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each
Securityholder.

         Notwithstanding replacement of the Trustee pursuant to this Section
9.8, the Company's obligations under Section 9.7 shall continue for the benefit
of the retiring Trustee.

SECTION 9.9. SUCCESSOR TRUSTEE BY MERGER, ETC.

         If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all of its corporate trust assets (including the
administration of this Indenture) to, another corporation, the resulting,
surviving or transferee corporation without any further act shall be the
successor Trustee; provided such transferee corporation shall qualify and be
eligible under Section 9.10.

SECTION 9.10. ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust process, having (together with any Person
directly or indirectly controlling the Trustee) a combined capital and surplus
of at least $25,000,000, subject to supervision or examination by federal or
state authority. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section 9.10, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 9.10, it shall resign immediately in the
manner and with the effect specified above in this Article 9.

SECTION 9.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         The Trustee shall comply with TIA 311(a), excluding any creditor
relationship listed in TIA 311(b). A trustee who has resigned or been removed
shall be subject to TIA 311(a) to the Government Obligations in accordance with
Section 10.1; provided, however, that if the Company has made any payment of the
principal of or premium, if any, or interest on any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive any such payment from the money or
U.S. Government Obligations held by the Trustee or the Paying Agent.

                                  ARTICLE 10.

SECTION 10.1. TERMINATION OF COMPANY'S OBLIGATIONS.

         The Company may terminate all of its obligations under the Securities
and this Indenture (except those obligations referred to in the immediately
succeeding paragraph) if all Securities previously authenticated and delivered
(other than destroyed, lost or stolen Securities which have been replaced or
paid or Securities for whose payment money has theretofore been held in trust

                                       66
<PAGE>

and thereafter repaid to the Company, as provided in Section 10.3) have been
delivered to the Trustee for cancellation and the Company has paid all sums
payable by it hereunder, or if the Company irrevocably deposits in trust with
the Trustee money or U.S. Government Obligations maturing as to principal and
interest in such amounts and at such times as are sufficient, without
consideration of any reinvestment of such interest, to pay the principal of and
premium, if any, and interest on the Securities then outstanding to maturity or
to the date fixed for redemption and to pay all other sums payable by it
hereunder. The Company may make an irrevocable deposit pursuant to this Section
10.1 only if at such time it is not prohibited from doing so under the
provisions of Article 5 and the Company shall have delivered to the Trustee and
any such Paying Agent an Officers' Certificate and Opinion of Counsel to that
effect and that all other conditions to such deposit have been complied with.

         The Company's obligations in paragraphs 8 and 12 of the Securities, in
Sections 6.1, 6.2, 9.7, 9.8 and 10.4, and in Articles 2 and 4 shall survive
until the Securities are no longer outstanding. Thereafter, the Company's
obligations in such paragraph 12 and in Section 9.7 shall survive.

         After such irrevocable deposit, the Trustee upon request shall
acknowledge in writing the discharge of the Company's obligations under the
Securities and this Indenture, except for those surviving obligations specified
above.

         "U.S. Government Obligations" means direct non-callable obligations of,
or non-callable obligations guaranteed by, the United States of America for the
payment of which guarantee or obligation the full faith and credit of the United
States is pledged.

SECTION 10.2. APPLICATION OF TRUST MONEY.

         The Trustee or the Paying Agent shall hold in trust, for the benefit of
the Holders, money or U.S. Government Obligations deposited with it pursuant to
Section 10.1, and shall apply the deposited money and the money from U.S.
Government Obligations in accordance with this Indenture to the payment of the
principal of, premium, if any, and interest on the Securities. Money and U.S.
Government Obligations so held in trust and deposited in compliance with Section
10.1 and Article 5 shall not be subject to the subordination provisions of
Article 5.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 10.1 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of outstanding Securities.

SECTION 10.3. REPAYMENT TO COMPANY.

         Subject to Section 10.1, the Trustee and the Paying Agent shall
promptly pay to the Company upon request any excess money or U.S. Government
Obligations held by them at any time.

         The Trustee and the Paying Agent shall pay, subject to applicable
escheatment laws, to the Company upon request any money held by them for the
payment of principal, premium, if any, or interest that remains unclaimed for
two years after a right to such money has matured.

                                       67
<PAGE>

After that, Holders entitled to money must look to the Company for payment
unless an abandoned property law designates another person.

SECTION 10.4. REINSTATEMENT.

         If the Trustee or the Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 10.1 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture and the Securities shall be revived
and reinstated as though no deposit had occurred pursuant to Section 10.1 until
such time as the Trustee or Paying Agent is permitted to apply all such money or
U.S. Government Obligations in accordance with Section 10.1; provided, however,
that if the Company has made any payment of the principal of or premium or
interest on any Securities because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Securities to
receive any such payment from the money or U.S. Government Obligations held by

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 11.1. WITHOUT CONSENT OF HOLDERS.

         The Company and the Trustee may amend or supplement this Indenture or
the Securities without notice to or consent of any Securityholder:

         (a) to comply with Sections 4.12, 6.3 and 7.1;

         (b) to cure any ambiguity, omission, defect or inconsistency, or to
make any other change that does not adversely affect the rights of any
Securityholder or would provide additional rights or benefits to the holders of
the Securities;

         (c) to make provisions with respect to the conversion right of the
Holders pursuant to Section 4.6;

         (d) to evidence and provide for the acceptance of appointment hereunder

of certificated Securities.

SECTION 11.2. WITH CONSENT OF HOLDERS.

         The Company and the Trustee may amend or supplement this Indenture or
the Securities without notice to any Securityholder but with the written consent
of the Holders of a majority in

                                       68

aggregate principal amount of the Securities then outstanding. The Holders of a
majority in aggregate principal amount of the Securities then outstanding may
waive: (i) compliance by the Company with restrictive provisions of this
Indenture or amend, modify or supplement this Indenture, other than as set forth
in this Section 11.2 below; and (ii) any past default under this Indenture and
its consequences, except a default in the payment of the principal of or any
premium or interest (including Contingent Interest, if any) on any Security or
in respect of a provision which under this Indenture cannot be modified or
amended without the consent of the Holder of each outstanding Security affected.

         Subject to Section 11.4, without the written consent of each
Securityholder affected, however, an amendment, supplement or waiver, including
a waiver pursuant to Section 8.4, may not:

         (a) change the stated maturity date of the principal of, or any
installment of interest (including Contingent Interest and Liquidated Damages,
if any) on, any Security;

         (b) reduce the principal amount of, or the rate of interest (including
Contingent Interest and Liquidated Damages, if any) or any premium payable on,
any Security, whether upon acceleration, redemption or otherwise;

         (c) change the currency for payment of principal of, or premium or
interest (including Contingent Interest and Liquidated Damages, if any) on any
Security;

         (d) impair the right to institute suit for the enforcement of any
payment of principal of, or premium or interest on any Security when due;

         (e) adversely affect the conversion rights provided in Article 4;

         (f) change the number of shares of Common Stock issuable upon

         (g) change the redemption provisions of this Indenture in a manner
adverse to the Holders of Securities;

         (h) modify the provisions of Article 5 with respect to the
subordination of the Securities in a manner adverse to the Holders of the
Securities;

         (i) modify the provisions of this Indenture requiring the Company to
make an offer to repurchase Securities upon a Change of Control or on January
16, 2010, January 16, 2014, or January 16, 2019 in a manner adverse to the
Holders of the Securities;

         (j) reduce the percentage of principal amount of the outstanding
Securities necessary to modify or amend this Indenture or to consent to any
waiver provided for in this Indenture; or

         (k) waive a default in the payment of the principal of or premium or
interest (including Contingent Interest or Liquidated Damages, if any) on any
Security.

                                       69
<PAGE>

         It shall not be necessary for the consent of the Holders under this
Section 11.2 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

         An amendment under this Section 11.2 may not make any change that
adversely affects the rights under Article 5 of any holder of an issue of Senior
Indebtedness unless the holders of that issue, pursuant to its terms, consent to
the change.

SECTION 11.3. COMPLIANCE WITH TRUST INDENTURE ACT.

         Every amendment to or supplement of this Indenture or the Securities
shall comply with TIA as in effect at the date of such amendment or supplement.

SECTION 11.4. REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder 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. However, 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 the amendment, supplement or waiver becomes
effective.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder, unless it makes a change described in any of clauses
(a) through (k) of Section 11.2. In that case the amendment, supplement or
waiver shall bind each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security.

SECTION 11.5. NOTATION ON OR EXCHANGE OF SECURITIES.

         If an amendment, supplement or waiver changes the terms of a Security,
the Trustee may require the Holder of the Security to deliver it to the Trustee.
The Trustee may place an appropriate notation on the Security about the changed
terms and return it to the Holder. Alternatively, if the Company or the Trustees
determines, the Company in exchange for the Security shall issue and the Trustee
shall authenticate a new Security that reflects the changed terms.

SECTION 11.6. TRUSTEE TO SIGN AMENDMENTS, ETC.; NOTICES.

         The Trustee shall sign any amendment or supplement authorized pursuant
to this Article 11 if the amendment or supplement does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may but need not sign it. In signing or refusing to sign such amendment
or supplement, the Trustee shall be entitled to receive and, subject to Section
9.1, shall be fully protected in relying upon, an Opinion of Counsel stating
that such amendment or supplement is authorized or permitted by this Indenture.
The Company may not sign an amendment or supplement until the Board of Directors
approves it.

                                       70
<PAGE>

         After an amendment, supplement or waiver under this Article 11 becomes
effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment, supplement or waiver. Any failure of the
Company to mail such notice, or any defect therein, shall not, however, in
anyway impair or affect the validity of any such amendment, supplement or
waiver.

                                  ARTICLE 12.

                                  MISCELLANEOUS

from January 16, 2004. Interest will be computed on the basis of a 360-day year
of twelve 30-day months.

         The Company shall pay additional interest ("Contingent Interest") to
the Holders during any six-month period (a "Contingent Interest Period") from
January 16 to, but excluding, July 16 and from July 16 to, but excluding,
January 16, with the initial six-month period commencing January 16, 2008, if
the average of the Trading Price for the five Trading Days ending on the third
Trading Day immediately preceding the first day of the applicable Contingent
Interest Period (the "Contingent Interest Average Trading Price") equals $1,200
or more. The amount of Contingent Interest payable per $1,000 principal amount
of Notes in respect of any Contingent Interest Period shall equal 0.50% per
annum of the Contingent Interest Average Trading Price. The Company will pay
Contingent Interest, if any, in the same manner as it will pay interest as
described above.

         Upon determination that Holders will be entitled to receive Contingent
Interest for a Contingent Interest Period, on or prior to the first day of such
Contingent Interest Period, the Company shall issue a press release and notify
the Trustee.

         The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated as of January 16, 2004, among the Company, Deutsche Bank
Securities Inc. ("DBSI"), Wachovia Capital Markets, LLC, Scotia Capital (USA)
Inc., BNY Capital Markets, Inc., NatCity Investments, Inc., and Wells Fargo
Securities, LLC.

2.       Method of Payment.

         The Company will pay interest on this Note (except defaulted interest)
to the person who is the registered Holder of this Note at the close of business
on January 1 and July 1 immediately preceding the interest payment date, or if
such day is not a Business Day, on the next succeeding Business Day. The Holder
must surrender this Note to the Paying Agent to collect payment of principal.
The Company will pay principal and interest in money of the United States that
at the time of payment is legal tender for payment of public and private debts.
The Company, however, may pay principal and interest by its check payable in
such money. It may mail an interest check to the Holder's registered address.

3.       Paying Agent, Registrar and Conversion Agent.

         Initially, The Bank of New York (the "Trustee") will act as Paying
Agent, Registrar and Conversion Agent. The Company may change any Paying Agent,
Registrar or Conversion Agent without notice to the holder. The Company or any
of its Subsidiaries may act as Paying Agent, Registrar or Conversion Agent.

4.       Indenture; Limitations.

         This Note is one of a duly authorized issue of Notes of the Company
designated as its 4% Contingent Convertible Subordinated Notes Due 2024 (the
"Notes"), issued under an Indenture dated as of January 16, 2004 (the
"Indenture"), between the Company and the Trustee. The terms of this Note
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb),
as amended by the Trust Indenture Reform Act of 1990, as in effect on the date
hereof or, from and after the date that the Indenture shall be qualified
thereunder, as in effect on such date. This Note is subject to all such terms,
and the holder of this Note is referred to the Indenture and said Act for a
statement of them.

         The Notes are subordinated unsecured obligations of the Company limited
to up to $100,000,000 aggregate principal amount plus an additional principal
amount not exceeding $25,000,000 in the aggregate as may be issued upon the
exercise by DBSI, in whole or in part, of the Purchase Option.

5.       Optional Redemption

         Beginning on January 19, 2010, the Company may redeem the Notes, in
whole at any time, or in part from time to time, for cash at a price equal to
100% of the principal amount of the Notes plus accrued but unpaid interest
(including Contingent Interest and Liquidated Damages, if any) up to but not
including the date of redemption payable in cash.

         In addition, on or after January 19, 2008, the Company may redeem the
Notes, in whole or in part, for cash at a price equal to 100% of the principal
amount of the Notes plus accrued but unpaid interest (including Contingent
Interest and Liquidated Damages, if any) up to but not including the date of
redemption, in the event that the Closing Price of the Company's Common Stock
for at least 20 Trading Days in the period of 30 consecutive Trading Days ending
on the last trading day of the calendar month preceding the calendar month in
which the notice of redemption is properly mailed to Holders is more than 125%
of the Conversion Price on that 30th Trading Day.

6.       Notice of Redemption.

         Notice of redemption will be mailed by first class mail at least 30
days but no more than 60 days prior to the redemption date in the case of a
Optional Redemption, and at least 20 days but not more than 60 days before the
redemption date in the case of an Optional Redemption, to each Holder of Notes
to be redeemed at his registered address. Notes in denominations larger than
$1,000 may be redeemed in part, but only in whole multiples of $1,000. On and
after

                                       81
<PAGE>

the redemption date, subject to the deposit with the Paying Agent of funds
sufficient to pay the redemption price, interest ceases to accrue on Notes or
portions of them called for redemption.

7.       Repurchase by the Company at the Option of the Holder; Repurchase at
         the Option of the Holder Upon a Change in Control.

         Subject to the terms and conditions of the Indenture, the Company shall
become obligated to purchase, at the option of the Holder, all or any portion of
the Notes held by such Holder, in any integral multiple of $1,000, on January
16, 2010, January 16, 2014 and January 16, 2019 (each, a "Repurchase Date") at a
purchase price per Security equal to 100% of the aggregate principal amount of
the Security (the "Repurchase Price"), together with accrued but unpaid interest
(including Contingent Interest and Liquidated Damages, if any) thereon, up to
but not including the Repurchase Date upon delivery of a Repurchase Notice
containing the information set forth in the Indenture, together with the Notes
subject thereto, at any time from the opening of business on the date that is 20
Business Days prior to such Repurchase Date until the close of business on such
Repurchase Date, and upon delivery of the Notes to the Paying Agent by the
Holder as set forth in the Indenture.

         At the option of the Holder and subject to the terms and conditions of
the Indenture, the Company shall become obligated to purchase the Notes held by
such Holder after the occurrence of a Change in Control of the Company for a
Change in Control Repurchase Price equal to 100% of the principal amount thereof
plus accrued but unpaid interest (including Contingent Interest and Liquidated
Damages, if any) thereon, up to but not including the Change in Control
Repurchase Date which Change in Control Repurchase Price shall be paid in cash
(provided that, if the Change in Control Repurchase Date is on or after an
interest record date but on or prior to the related interest payment date,
accrued but unpaid interest will be payable to the Holders in whose names the
Notes are registered at the close of business on the relevant record date).

         Holders have the right to withdraw any Repurchase Notice or Change in
Control Repurchase Notice, as the case may be, by delivering to the Paying Agent
a written notice of withdrawal in accordance with the provisions of the
Indenture.

         Subject to the terms and conditions of the Indenture, the Company will
make payments in respect of the Redemption Price, Repurchase Price, Change in
Control Repurchase Price and the principal amount of the Notes, as the case may
be, to the Holder who surrenders a Note to a Paying Agent to collect such
payments in respect of the Note. The Company will pay cash amounts in money of
the United States that at the time of payment is legal tender for payment of
public and private debts. However, the Company may pay interest (including
Contingent Interest and Liquidated Damages, if any), the Redemption Price,
Repurchase Price, Change in Control Repurchase Price and the principal amount,
as the case may be, by check or wire payable in such money; provided, however,
that a Holder holding Notes with an aggregate principal amount in excess of
$5,000,000 may request payment by wire transfer in immediately available funds
to an account in North America at the election of such Holder. The Company may
mail an interest check to the Holder's registered address. Notwithstanding the
foregoing, so long as this Note is registered in the name of a Depositary or its
nominee, all payments hereon shall be made by wire transfer of immediately
available funds to the account of the Depositary or its nominee.

                                       82

8.       Conversion.

         Subject to the provisions of Article 4 of the Indenture, a Holder of a
Note may convert such Note into shares of Common Stock of the Company if any of
the conditions specified in paragraphs (a) through (e) of Section 4.1 of the
Indenture is satisfied; provided, however, that if such Note is called for
redemption, the conversion right will terminate at the close of business on the
third Business Day immediately preceding the Redemption Date of such Note
(unless the Company shall default in making the redemption payment when due, in
which case the conversion right shall terminate at the close of business on the
date such Default is cured and such Note is redeemed). The initial conversion
price is $15.43 per share, subject to adjustment under certain circumstances as
described in the Indenture (the "Conversion Price"). The number of shares
issuable upon conversion of a Note is determined by dividing the principal
amount of Notes converted by the Conversion Price in effect on the Conversion
Date. Upon conversion, no adjustment for interest (including Contingent Interest
and Liquidated Damages, if any) or dividends will be made. No fractional shares
will be issued upon conversion; in lieu thereof, an amount will be paid in cash
based upon the Closing Price of the Common Stock on the last Trading Day prior
to the date of conversion.

         To convert a Note, a Holder must (a) complete and sign the conversion
notice set forth below and deliver such notice to the Conversion Agent, (b)
surrender the Note to the Conversion Agent, (c) furnish appropriate endorsements
and transfer documents if required by the Registrar or the Conversion Agent, (d)
pay any transfer or similar tax, if required and (e) if the Note is held in
book-entry form, complete and deliver to the Depositary appropriate instructions
pursuant to the Depositary's book-entry conversion programs. If a Holder
surrenders a Note for conversion between the record date for the payment of an
installment of interest and the related interest payment date, the Note must be
accompanied by payment of an amount equal to the interest (including Contingent
Interest and Liquidated Damages, if any) payable on such interest payment date
on the principal amount of the Note or portion thereof then converted; provided,
however, that no such payment shall be required if such Note has been called for
redemption on a Redemption Date within the period between and including such
record date and such interest payment date, or if such Note is surrendered for
conversion on the interest payment date. A Holder may convert a portion of a
Note equal to $1,000 or any integral multiple thereof.

         A Note in respect of which a Holder has delivered a Repurchase Notice
or a Change of Control Repurchase Notice exercising the option of such Holder to
require the Company to repurchase such Note as provided in Section 3.9 or
Section 3.10, respectively, of the Indenture may be converted only if such
notice of exercise is withdrawn in accordance with the terms of the Indenture.

9.       Subordination.

         The indebtedness evidenced by the Notes is, to the extent and in the
manner provided in the Indenture, subordinate and junior in right of payment to
the prior payment in full of all Senior Indebtedness of the Company, as defined
in the Indenture. Any Holder by accepting this Note agrees to and shall be bound
by such subordination provisions and authorizes the Trustee to give them effect.

                                       83
<PAGE>

         In addition to all other rights of Senior Indebtedness described in the
Indenture, the Senior Indebtedness shall continue to be Senior Indebtedness and
entitled to the benefits of the subordination provisions irrespective of any
amendment, modification or waiver of any terms of any instrument relating to the
Senior Indebtedness or any extension or renewal of the Senior Indebtedness.

10.      Denominations, Transfer, Exchange.

         The Notes are in registered form without coupons in denominations of
$1,000 and integral multiples thereof. A Holder may register the transfer of or
exchange Notes in accordance with the Indenture. The Registrar may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes or other governmental charges that may be imposed
by law or permitted by the Indenture.

         The aggregate principal amount of the Note in global form represented
hereby may from time to time be reduced to reflect conversions or redemptions of
a part of this Note in global form or cancellations of apart of this Note in
global form, in each case, and in any such case, by means of notations on the
Global Note Transfer Schedule on the last page hereof. Notwithstanding any
provision of this Note to the contrary, conversions or redemptions of a part of
this Note in global form and cancellations of a part of this Note in global
form, may be effected without the surrendering of this Note in global form,
provided that appropriate notations on the Schedule of Exchanges, Conversions,
Redemptions, Cancellations and Transfers are made by the Trustee, or the
Custodian at the direction of the Trustee, to reflect the appropriate reduction
or increase, as the case may be, in the aggregate principal amount of this Note
in a global form resulting therefrom or as a consequence thereof.

11.      Persons Deemed Owners.

         The registered holder of a Note may be treated as the owner of it for
all purposes.

12.   Unclaimed Money.

         If money for the payment of principal, premium, if any, or interest
remains unclaimed for two years, the Trustee or Paying Agent will pay, subject
to applicable escheatment laws, the money back to the Company at its request.
After that, Holders entitled to money must look to the Company for payment
unless an abandoned property law designates another person.

13.  Amendment, Supplement, Waiver.

         Subject to certain exceptions, the Indenture or the Notes may be
amended or supplemented with the consent of the Holders of a majority in
aggregate principal amount of the Notes then outstanding and any past default or
compliance with any provision may be waived in a particular instance with the
consent of the Holders of a majority in aggregate principal amount of the Notes
then outstanding. Without the consent of or notice to any Holder, the Company
and the Trustee may amend or supplement the Indenture or the Notes to, among
other things, cure any ambiguity, omission, defect or inconsistency or make any
other change that does not adversely affect the rights of any Holder.

                                       84
<PAGE>

14.  Successor Corporation.

         When a successor corporation assumes all the obligations of its
predecessor under the Notes and the Indenture, the predecessor corporation will
be released from those obligations.

15.  Defaults and Remedies.

         An Event of Default is: default for 30 days in payment of interest
(including Contingent Interest and Liquidated Damages, if any) on the Notes;
default in payment of principal on the Notes when due; failure by the Company
for 60 days after appropriate notice to it to comply with any of its other
agreements contained in the Indenture or the Notes; default by the Company or
any Subsidiary with respect to its obligation to pay principal of or interest on
indebtedness for borrowed money aggregating more than $10 million, beyond the
grace period, if any, provided in the instrument or agreement under which the
indebtedness was created, or the acceleration of such indebtedness if not
withdrawn within 30 days from the date of such acceleration; failure by the
Company to deliver shares of Common Stock within 15 days after such Common Stock
is required to be delivered upon conversion of a Note; and certain events of
bankruptcy, insolvency or reorganization of the Company or any of its
Significant Subsidiaries. If an Event of Default (other than as a result of
certain events of bankruptcy, insolvency or reorganization) occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the Notes then outstanding may declare all unpaid principal of and accrued
interest (including Contingent Interest and Liquidated Damages, if any) to the
date of acceleration on the Notes then outstanding to be immediately due and
payable, all as and to the extent provided in the Indenture. If an Event of
Default occurs as a result of certain events of bankruptcy, insolvency or
reorganization, all unpaid principal of and accrued interest (including
Contingent Interest and Liquidated Damages, if any) on the Notes then
outstanding shall become immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder, all as and to the extent
provided in the Indenture. Holders may not enforce the Indenture or the Notes
except as provided in the Indenture. The Trustee may require indemnity
satisfactory to it before it enforces the Indenture or the Notes. Subject to
certain limitations, Holders of a majority in principal amount of the Notes then
outstanding may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders notice of any continuing default (except a
default in payment of principal or interest) if it determines that withholding
notice is in their interests. The Company is required to file periodic reports
with the Trustee as to the absence of default.

16.  Trustee Dealings with the Company.

         The Bank of New York, the Trustee under the Indenture, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or an Affiliate of the Company, and may
otherwise deal with the Company or an Affiliate of the Company, as if it were
not the Trustee.

17.  No Recourse Against Others.

         A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the Notes
or the Indenture or for any claim

                                       85
<PAGE>

based on, in respect or by reason of, such obligations or their creation. The
Holder of this Note by accepting this Note waives and releases all such
liability. The waiver and release are part of the consideration for the issue of
this Note.

18.  Discharge Prior to Maturity.

         If the Company deposits with the Trustee or the Paying Agent money or
U.S. Government Obligations sufficient to pay the principal of and interest on
the Notes to maturity as provided in the Indenture, the Company will be
discharged from the Indenture except for certain Sections thereof.

19.  Authentication.

         This Note shall not be valid until the Trustee or an authenticating
agent signs the certificate of authentication on the other side of this Note.

20.  Abbreviations and Definitions.

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

         All capitalized terms used in this Note and not specifically defined
herein are defined in the Indenture and are used herein as so defined.

         In the case of any conflict between the provisions of this Note and the
Indenture, the provisions of the Indenture shall control.

         The Company will furnish to any Holder, upon written request and
without charge, a copy of the Indenture. Requests may be made to: GenCorp Inc.,

         This Registration Rights Agreement (this "Agreement") is dated as of
January 16, 2004, by and among GENCORP INC., an Ohio corporation (the

Markets, LLC ("BNY"), NatCity Investments, Inc. ("NatCity"), and Wells Fargo
Securities, LLC ("Wells Fargo") (DBSI, Wachovia, Scotia Capital, BNY, NatCity
and Wells Fargo, individually, an "Initial Purchaser" and together, the "Initial
Purchasers").

         This Agreement is entered into in connection with the Purchase
Agreement, dated as of January 12, 2004 (the "Purchase Agreement"), by and
between the Company and DBSI, as Representative of the Initial Purchasers (in
such capacity, the "Representative"), which provides for the sale by the Company
to the Initial Purchasers of $100,000,000 aggregate principal amount of the
Company's 4% Contingent Convertible Subordinated Notes Due 2024 (the "Firm
Notes"), which are convertible into Common Stock of the Company, par value $0.10
per share (the "Underlying Shares"), plus up to an additional $25,000,000
aggregate principal amount of the same which DBSI may subsequently elect to
purchase pursuant to the terms of the Purchase Agreement (the "Additional Notes"
and, together with the Firm Notes, the "Convertible Notes"). The Convertible
Notes are being issued pursuant to an Indenture dated as of January 16, 2004
(the "Indenture"), between the Company and The Bank of New York, as trustee (as
amended or supplemented from time to time, the "Indenture").

Notes or Underlying Shares as provided herein. The execution and delivery of

2.       Shelf Registration.

or applicable interpretation of the staff of the SEC, a Registration Statement
for an offering to be made on a continuous basis pursuant to Rule 415 covering
all of the Registrable Securities (the "Initial Shelf Registration") on or prior
to the Filing Date.

         The Initial Shelf Registration shall be on Form S-3 or another
appropriate form permitting registration of such Registrable Securities for
resale by Holders in the manner or manners set forth in such Registration
Statement and in Rule 415. The Company shall not permit any securities other
than the Registrable Securities to be included in the Initial Shelf Registration
or any Subsequent Shelf Registration (as defined below).

         The Company shall use its reasonable best efforts to cause the Initial
Shelf Registration to be declared effective under the Securities Act on or prior
to the Effectiveness Date and to keep such Initial Shelf Registration
continuously effective under the Securities Act until the date that is two years
from the later of the Closing Date and the last Option Closing Date (as it may
be shortened pursuant to clause (i), (ii) or (iii) immediately following, the
"Effectiveness Period"), or such shorter period ending when (i) all the
Registrable Securities covered by the Initial Shelf Registration have been sold
in the manner set forth and as contemplated in the Initial Shelf Registration,
(ii) the date on which all the Registrable Securities (x) held by Persons who
are not affiliates of the Company may be resold pursuant to Rule 144(k) under
the Securities Act or (y) cease to be outstanding, or (iii) a Subsequent Shelf
Registration covering all of the Registrable Securities has been declared
effective under the Securities Act.

                                     - 4 -
<PAGE>

         Each Holder wishing to include its Registrable Securities in the
Initial Shelf Registration Statement prior to the time it is declared effective
agrees to deliver a written notice, substantially in the form of Annex A to the
Final Memorandum dated January 12, 2004 used in connection with the offer of the
Convertible Notes (a "Notice and Questionnaire"), to the Company not later than
15 days after the last date of original issuance of the Convertible Notes or, if
later, five Business Days prior to the effective date of the Shelf Registration
Statement (each Holder delivering a Notice and Questionnaire, a "Notice
Holder"). From and after the date the Shelf Registration Statement is declared
effective, the Company shall, as promptly as reasonably practicable after the
date of receipt of a Notice and Questionnaire (and, in any event, within 15
Business Days), (i) if required by applicable law, file with the SEC a
post-effective amendment to the Shelf Registration Statement or prepare and, if
required by applicable law, file a supplement to the related Prospectus or a
supplement or amendment to any document incorporated therein by reference or
file any other document required under the Securities Act so that the Holder
delivering such Notice and Questionnaire is named as a selling securityholder in
the Shelf Registration Statement and the related Prospectus in such a manner as
to permit such Holder to deliver such Prospectus to purchasers of the
Registrable Securities in accordance with applicable law and, if the Company
shall file a post-effective amendment to the Shelf Registration Statement, use
reasonable best efforts to cause such post-effective amendment to be declared
effective under the Securities Act as promptly as is practicable, but in any
event not later than 60 Business Days after the date such post-effective
amendment is required by this clause to be filed; (ii) provide such Holder
copies of any documents filed pursuant to subheading (i) of this paragraph; and
(iii) notify such Holder as promptly as practicable after the effectiveness
under the Securities Act of any post-effective amendment filed pursuant to
subheading (i) of this paragraph; provided that if such Notice and Questionnaire
is delivered during a period pursuant to Section 3(b), the Company shall so
inform the Holder delivering such Notice and Questionnaire and shall take the
actions set forth in clauses (i), (ii) and (iii) above upon expiration of any
period referenced in Section 3(b) of this Agreement. Any Holder who, subsequent
to the date the Registration Statement is declared effective, provides a Notice
and Questionnaire required by this paragraph pursuant to the provisions of this
Section (whether or not such Holder has supplied the Notice and Questionnaire at
the time the Shelf Registration Statement was declared effective) shall be named
as a selling securityholder in the Shelf Registration Statement and related
Prospectus in accordance with the requirements of this paragraph.

         No Holder of Registrable Securities may include any of its Registrable
Securities in any Shelf Registration pursuant to this Agreement unless and until
such Holder furnishes to the Company a completed and executed Notice and
Questionnaire. Each Holder of Registrable Securities as to which any Shelf
Registration Statement is being effected agrees to furnish, in accordance with
the previous paragraph, to the Company all information required to be disclosed
so that the information previously furnished to the Company by such Holder is
not materially misleading and does not omit to state a material fact required to
be stated therein or necessary in order to make the statements therein not
misleading in the light of the circumstances under which they were made and, if
such Holder fails to do so, the Company shall be under no obligation to include
such Holder's Registrable Securities in any Shelf Registration Statement.

         (b) Withdrawal of Stop Orders. If the Initial Shelf Registration or any
Subsequent Shelf Registration ceases to be effective for any reason at any time
during the

                                     - 5 -
<PAGE>

Effectiveness Period (other than because of the sale of all of the securities
registered thereunder), the Company shall use its reasonable best efforts to
obtain the prompt withdrawal of any order suspending the effectiveness thereof,
and in any event shall within 30 days of such cessation of effectiveness amend
the Initial Shelf Registration or Subsequent Shelf Registration, as the case may
be, in a manner to obtain the withdrawal of the order suspending the
effectiveness thereof.

         (c) Supplements and Amendments. The Company shall promptly supplement
and amend the Shelf Registration (as defined below) if required by the rules,
regulations, or instructions applicable to the registration form used for such
Shelf Registration or if required by the Securities Act and will use its
reasonable best efforts to reflect in such supplement or amendment such comments
as Holders of the majority in Amount of Registrable Securities covered by such
Registration Statement or any underwriter of such Registrable Securities may
reasonably propose with respect to the information included therein that relates
to one or more of such Holders or underwriters. As used herein, the term "Shelf
Registration" means the Initial Shelf Registration and any Subsequent Shelf
Registration and the term "Shelf Registration Statement" means any Registration
Statement filed in connection with a Shelf Registration.

3.       Liquidated Damages.

         (a) The Company and the Initial Purchasers agree that the Holders of
Registrable Securities will suffer damages if the Company fails to fulfill its
obligations under Section 2 hereof and that it would not be feasible to
ascertain the extent of such damages with precision. Accordingly, the Company
agrees to pay liquidated damages on the Registrable Securities ("Liquidated
Damages") under the circumstances and to the extent set forth below, each of
which shall be given independent effect (each a "Registration Default"):

                  (i) if the Initial Shelf Registration is not filed with the
SEC on or prior to the Filing Date, then commencing on the day after the Filing
Date, Liquidated Damages shall accrue on the Registrable Securities at a rate of
0.50% per annum on the Amount of Registrable Securities;

                  (ii) if the Initial Shelf Registration or a Subsequent Shelf
Registration is not declared effective by the SEC on or prior to the
Effectiveness Date, then commencing one day after the Effectiveness Date,
Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.50%
per annum on the Amount of Registrable Securities;

                  (iii) if a Shelf Registration has been declared effective and
such Shelf Registration ceases to be effective or the Prospectus therein fails
to be available for use at any time during the Effectiveness Period (other than
as permitted under Section 3(b)), then Liquidated Damages shall accrue on the
Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable
Securities; and

                  (iv) if the Company fails with respect to a Notice Holder to
amend or supplement the Shelf Registration Statement in a timely manner in
accordance with Section 2 in order to name such Notice Holder as a selling
securityholder, then Liquidated Damages shall accrue on the Registrable
Securities held by such Notice Holder at a rate of 0.50% per annum on the Amount
of Registrable Securities held by such Notice Holder;

                                     - 6 -
<PAGE>

provided, however, that Liquidated Damages on Registrable Securities held by any
Holder may not accrue under more than one of the foregoing clauses (i), (ii),
(iii) or (iv) at any one time; provided, further, however, that (1) upon the
filing of the Shelf Registration as required hereunder (in the case of clause
(a)(i) of this Section 3), (2) upon the effectiveness of the Shelf Registration
as required hereunder (in the case of clause (a)(ii) of this Section 3), (3)
upon the effectiveness or availability of a Shelf Registration or Prospectus
which had ceased to remain effective or available (in the case of clause
(a)(iii) of this Section 3) or (4) upon inclusion of such Notice Holder in a
Shelf Registration Statement (in the case of clause (a)(iv) of this Section 3),
Liquidated Damages on the Registrable Securities as a result of such clause (or
the relevant subclause thereof) shall cease to accrue. It is understood and
agreed that, notwithstanding any provision to the contrary, so long as any
Registrable Security is then covered by an effective Shelf Registration
Statement containing a usable Prospectus, no Liquidated Damages shall accrue on
such Registrable Security.

         (b) Notwithstanding paragraph (a) of this Section 3, if the Board of
Directors of the Company determines that it is in the best interest of the
Company not to disclose the existence of or facts surrounding any proposed or
pending material corporate transaction or development involving the Company or
its subsidiaries, the Company may suspend the filing or effectiveness of a Shelf
Registration or the use of any related Prospectus for up to 30 consecutive days
in any 90-day period for a total of not more than 90 days in any calendar year,
without paying Liquidated Damages, and, upon notice thereof to each Holder, such
Holder shall suspend the use of the Shelf Registration Statement and the related
Prospectus until such time as the Company shall have notified such Holder that
the Shelf Registration Statement and the related Prospectus are again available
for use.

         (c) So long as Convertible Notes remain outstanding, the Company shall
notify the Trustee within three Business Days after each and every date on which
an event occurs in respect of which Liquidated Damages is required to be paid.
Any amounts of Liquidated Damages due pursuant to clause (a)(i), (a)(ii),
(a)(iii) or (a)(iv) of this Section 3 will be payable in cash semi-annually on
each January 16 and July 16 (each a "Damages Payment Date"), commencing with the
first such date occurring after any such Liquidated Damages commences to accrue,
to Holders to whom regular interest is payable on such Damages Payment Date with
respect to Convertible Notes that are Registrable Securities and to Persons that
are registered Holders 15 days prior to such Damages Payment Date with respect
to Underlying Shares that are Registrable Securities. The amount of Liquidated
Damages for Registrable Securities will be determined by multiplying the
applicable rate of Liquidated Damages by the Amount of Registrable Securities
outstanding on the Damages Payment Date following such Registration Default in
the case of the first such payment of Liquidated Damages with respect to a
Registration Default (and thereafter at the next succeeding Damages Payment Date
until the cure of such Registration Default), multiplied by a fraction, the
numerator of which is the number of days such Liquidated Damages rate was
applicable during such period (determined on the basis of a 360-day year
comprised of twelve 30-day months and, in the case of a partial month, the
actual number of days elapsed), and the denominator of which is 360. No
Liquidated Damages shall accrue with respect to securities that are not
Registrable Securities.

4.       Registration Procedures.In connection with the filing of any
Registration Statement pursuant to Section 2 hereof, the Company shall effect
such registrations to permit the sale of the

                                     - 7 -
<PAGE>

securities covered thereby in accordance with the intended method or methods
of disposition thereof, and pursuant thereto and in connection with any
Registration Statement filed by the Company hereunder the Company shall:

         (a) Use its reasonable best efforts to prepare and file with the SEC on
or prior to the Filing Date, a Registration Statement or Registration Statements
as prescribed by Section 2 hereof, and use its reasonable best efforts to cause
each such Registration Statement to become effective and remain effective as
provided herein; provided, however, that before filing any Registration
Statement or Prospectus or any amendments or supplements thereto, the Company
shall furnish to and afford the Holders of the Registrable Securities covered by
such Registration Statement and their counsel if requested by the Holders and
the managing underwriters, if any, upon their request, a reasonable opportunity
to review copies of all such documents proposed to be filed, other than
documents filed with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of
the Exchange Act that are deemed incorporated by reference in such Registration
Statement or Prospectus (in each case, where possible, at least three Business
Days prior to such filing, or such later date as is reasonable under the
circumstances). The Company shall not file any Registration Statement or
Prospectus or any amendments or supplements thereto if the Holders of a majority
in Amount of Registrable Securities covered by such Registration Statement shall
reasonably object on a timely basis.

         (b) Use its reasonable best efforts to prepare and file with the SEC
such amendments and post-effective amendments to each Shelf Registration as may
be necessary to keep such Registration Statement continuously effective for the
Effectiveness Period; cause the related Prospectus to be supplemented by any
Prospectus supplement required by applicable law, and as so supplemented to be
filed pursuant to Rule 424 (or any similar provisions then in force) promulgated
under the Securities Act; and comply in all material respects with the
provisions of the Securities Act and the Exchange Act applicable to it with
respect to the disposition of all securities covered by such Registration
Statement as so amended or in such Prospectus as so supplemented. Subject to
Section 3(b), the Company shall be deemed not to have used its reasonable best
efforts to keep a Registration Statement effective during the Effectiveness
Period if it voluntarily takes any action that would result in selling Holders
of the Registrable Securities covered thereby not being able to sell such
Registrable Securities during that period unless such action is required by
applicable law or unless the Company complies with this Agreement, including
without limitation the provisions of Section 4(k) hereof.

         (c) Use its reasonable best efforts to notify the selling Holders of
Registrable Securities, their counsel and the managing underwriters, if any,
promptly (but in any event within five Business Days) (i) when a Prospectus or
any prospectus supplement or post-effective amendment has been filed, and, with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective under the Securities Act (including in such notice a
written statement that any Holder may, upon written request, obtain, at the sole
expense of the Company, one conformed copy of such Registration Statement or
post-effective amendment including financial statements and schedules, documents
incorporated or deemed to be incorporated by reference and exhibits), (ii) of
the issuance by the SEC of any stop order suspending the effectiveness of a
Registration Statement or of any order preventing or suspending the use of any
Prospectus or the initiation of any proceedings for that purpose, (iii) of the
happening of any event, the existence of any condition or any information
becoming known

                                     - 8 -
<PAGE>

that makes any statement made in such Registration Statement or related
Prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue in any material respect or that requires the making of any
material changes in or amendments or supplements to such Registration Statement,
Prospectus or documents so that, in each case, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading and (iv) of the
Company's determination that a post-effective amendment to a Registration
Statement would be appropriate.

         (d) Use its reasonable best efforts to prevent the issuance of any
order suspending the effectiveness of a Registration Statement or of any order
preventing or suspending the use of a Prospectus and, if any such order is
issued, to use its reasonable best efforts to obtain the withdrawal of any such
order at the earliest possible moment.

         (e) If requested by the managing underwriter or underwriters (if any)
or the Holders of the majority in Amount of Registrable Securities being sold in
connection with an underwritten offering, (i) as promptly as practicable
incorporate in a prospectus supplement or post-effective amendment such
information as the managing underwriter or underwriters (if any) or such Holders
reasonably determine is necessary to be included therein, (ii) make all required
filings of such prospectus supplement or such post-effective amendment as soon
as reasonably practicable after the Company has received notification of the
matters to be incorporated in such prospectus supplement or post-effective
amendment and (iii) supplement or make amendments to such Registration
Statement, provided, however, that the Company shall not be required to take any
action pursuant to this Section 4(e) that would, in the good faith judgment of
the Company, violate applicable law.

         (f) Use its reasonable best efforts to furnish to each selling Holder
of Registrable Securities and a single counsel to all such Holders (chosen in
accordance with Section 5(b)) and each managing underwriter, if any, at the sole
expense of the Company, one conformed copy of the Registration Statement or
Registration Statements and, if requested, each post-effective amendment
thereto, including financial statements and schedules, and all documents
incorporated or deemed to be incorporated therein by reference and all exhibits.

         (g) Use its reasonable best efforts to furnish to each selling Holder
of Registrable Securities and a single counsel to all such Holders (chosen in
accordance with Section 5(b)) and the underwriters, if any, at the sole expense
of the Company, as many copies of the Prospectus (including each form of
preliminary prospectus) and each amendment or supplement thereto and any
documents incorporated by reference therein as such Persons may reasonably
request in writing; and, subject to the last paragraph of this Section 4, the
Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the selling Holders of Registrable Securities and
the underwriters or agents, if any, and dealers (if any), in connection with the
offering and sale of the Registrable Securities covered by such Prospectus and
any amendment or supplement thereto in the manner contemplated by such
Prospectus.

         (h) Prior to any public offering of Registrable Securities, to use its
reasonable best efforts to register or qualify, to the extent required by
applicable law, and to cooperate with

                                     - 9 -
<PAGE>

the selling Holders of Registrable Securities and the managing underwriter or
underwriters, if any, in connection with the registration or qualification (or
exemption from such registration or qualification) of, such Registrable
Securities or offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any selling Holder, or the managing
underwriter or underwriters, if any, reasonably requests in writing; and use its
reasonable best efforts to keep each such registration or qualification (or
exemption therefrom) effective during the period such Registration Statement is
required to be kept effective and do any and all other acts or things reasonably
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by the applicable Registration Statement;
provided, however, that the Company shall not be required to (A) qualify
generally to do business in any jurisdiction where it is not then so qualified,
(B) take any action that would subject it to general service of process in any
such jurisdiction where it is not then so subject or (C) subject itself to
taxation in any such jurisdiction where it is not then so subject.

         (i) Cooperate with the selling Holders of Registrable Securities and
the managing underwriter or underwriters, if any, to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold, which certificates shall not bear any restrictive legends and shall be
in a form eligible for deposit with Depositary; and enable such shares of
Registrable Securities to be in such denominations subject to applicable
requirements contained in the Indenture and registered in such names as the
Holders may reasonably request.

         (j) Use its reasonable best efforts to cause the Registrable Securities
covered by any Shelf Registration Statement to be registered with or approved by
such other governmental agencies or authorities as may be reasonably necessary
to enable the seller or sellers thereof or the underwriter or underwriters, if
any, to consummate the disposition of such Registrable Securities, except as may
be required solely as a consequence of the nature of such selling Holder's
business, in which case the Company will cooperate in all reasonable respects
with the filing of such Registration Statement and the granting of such
approvals.

         (k) Upon the occurrence of any event contemplated by paragraph
4(c)(ii), 4(c)(iii) or 4(c)(iv) hereof, subject to Section 3(b), to use its
reasonable best efforts to prepare and (subject to Section 4(a) hereof) file
with the SEC, at the sole expense of the Company, a supplement or post-effective
amendment to the Registration Statement or a supplement to the related
Prospectus or any document incorporated or deemed to be incorporated therein by
reference, or file any other required document, so that, as thereafter delivered
to the purchasers of the Registrable Securities being sold thereunder, any such
Prospectus will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

         (l) In connection with any underwritten offering of Registrable
Securities pursuant to a Shelf Registration, enter into an underwriting
agreement on customary terms and conditions for underwritten offerings of
securities similar to the Registrable Securities and take all such other actions
as are reasonably requested by the managing underwriter in order to expedite or
facilitate the registration or the disposition of such Registrable Securities
and, in such connection, (i) make such representations and warranties to, and
covenants with, the underwriters with respect to the business of the Company and
its subsidiaries (including any

                                     - 10 -
<PAGE>

acquired business, properties or entity, if applicable) and the Registration
Statement, Prospectus and documents, if any, incorporated or deemed to be
incorporated by reference therein, in each case, as are customarily made by
issuers to underwriters in underwritten offerings of securities similar to the
Registrable Securities and confirm the same in writing if and when requested;
(ii) upon the request of the managing underwriter, use all reasonable efforts to
obtain the written opinion of counsel to the Company and written updates thereof
in form, scope and substance reasonably satisfactory to the managing underwriter
or underwriters, addressed to the underwriters covering the matters customarily
covered in opinions requested in underwritten offerings of securities similar to
the Registrable Securities and such other matters as may be reasonably requested
by the managing underwriter or underwriters; (iii) upon the request of the
managing underwriter, use all reasonable efforts to obtain "cold comfort"
letters and updates thereof in form, scope and substance reasonably satisfactory
to the managing underwriter or underwriters from the independent certified
public accountants of the Company (and, if necessary, any other independent
certified public accountants of any subsidiary of the Company or of any business
acquired by the Company for which financia1 statements and financial data are,
or are required to be, included or incorporated by reference in the Registration
Statement), addressed to each of the underwriters, such letters to be in
customary form and covering matters of the type customarily covered in "cold
comfort" letters in connection with underwritten offerings of securities similar
to the Registrable Securities and such other matters as are reasonably requested
by the managing underwriter or underwriters as permitted by the Statement on
Auditing Standards No. 72, provided that each such Holder and underwriter makes
such reasonable representations as may be customarily required for such
independent certified public accountants in similar transactions to deliver such
letters; and (iv) if an underwriting agreement is entered into, cause the same
to contain indemnification provisions and procedures no less favorable to the
sellers and underwriters, if any, than those set forth in Section 7 hereof (or
such other provisions and procedures reasonably acceptable to Holders of a
majority in Amount of Registrable Securities covered by such Registration
Statement and the managing underwriter or underwriters or agents, if any) with
respect to all parties to be indemnified pursuant to said Section. The above
shall be done as and to the extent required by such underwriting agreement.

         (m) Use its reasonable best efforts to make available for inspection by
any selling Holder of Registrable Securities being sold, any underwriter
participating in any such disposition of Registrable Securities, if any, and any
attorney, accountant or other agent retained by any such selling Holder, or
underwriter (collectively, the "Inspectors"), upon written request, at the
offices where normally kept, during reasonable business hours without
interfering in the orderly business of the Company at such time or times as
shall be mutually convenient for the Company and the Inspectors as a group, all
pertinent financial and other records, pertinent corporate documents and
instruments of the Company and its subsidiaries (collectively, the "Records") as
shall be reasonably necessary to enable the Inspectors to exercise any
applicable due diligence responsibilities, and cause the officers, directors and
employees of the Company and its subsidiaries to supply all information that has
been reasonably requested by any such Inspector in connection with such due
diligence responsibilities; provided, however, that the foregoing inspection and
information gathering shall be coordinated on behalf of such Holders by one firm
of counsel, which firm shall be Winston & Strawn LLP until another firm shall be
designated pursuant to Section 5(b). Any such access granted to the Inspectors
under this Section 4(m) shall be subject to the prior receipt by the Company of
written undertakings, in form and substance reasonably satisfactory to the
Company and its counsel, to preserve the

                                     - 11 -
<PAGE>

confidentiality of any Records deemed by the Company to be confidential. Records
that the Company determines, in good faith, to be confidential and any Records
that it notifies the Inspectors are confidential shall not be disclosed by any
Inspector unless (i) the release of such Records is ordered pursuant to a
subpoena or other order from a court of competent jurisdiction, (ii) after
giving reasonable prior notice to the Company, disclosure of such information
is, in the opinion of counsel for any Inspector, necessary in connection with
any action, claim, suit or proceeding, directly involving or potentially
involving such Inspector and arising out of, based upon, relating to, or
involving this Agreement or any transactions contemplated hereby or arising
hereunder or (iii) the information in such Records has been made generally
available to the public other than through the acts of such Inspector or an
"affiliate" (as defined in Rule 405) of any Inspector; provided, however, that
prior notice shall be provided as soon as practicable to the Company of the
potential disclosure of any information by such Inspector pursuant to clauses
(i) or (ii) of this sentence to permit the Company to undertake appropriate
action to prevent the disclosure of such Records (or waive the provisions of
this paragraph (m)). Each selling Holder of such Registrable Securities will be
required to agree that information obtained by it as a result of such
inspections shall be deemed confidential and shall not be used by it as the
basis for any market transactions in the securities of the Company, unless and
until such information in such Records has been made generally available to the
public other than as the result of a breach of this Agreement. Each Inspector
shall take such actions as are reasonably necessary to protect the
confidentiality of such information to the extent such actions are otherwise not
inconsistent with, an impairment of or in derogation of the rights and interests
of the Holder or any Inspector, unless and until such information in such
Records has been made generally available to the public other than as a result
of a breach of this Agreement.

         (n) Provide (i) the Holders of the Registrable Securities to be
included in such Registration Statement and not more than one counsel for all
the Holders of such Registrable Securities chosen in accordance with Section
5(b), (ii) the underwriters (which term, for purposes of this Agreement, shall
include a Person deemed to be an underwriter within the meaning of Section 2(11)
of the Securities Act), if any, thereof, (iii) the sales or placement agent, if
any, thereof, and (iv) one counsel for such underwriters or agents, reasonable
opportunity to participate in the preparation of such Registration Statement,
each Prospectus included therein or filed with the SEC, and each amendment or
supplement thereto.

         (o) Comply in all material respects with all applicable rules and
regulations of the SEC and make generally available to its securityholders
earnings statements satisfying the provisions of Section 11(a) of the Securities
Act and Rule 158 thereunder (or any similar rule promulgated under the
Securities Act) no later than 45 days after the end of any 12-month period (or
90 days after the end of any 12-month period if such period is a fiscal year)
(i) commencing at the end of any fiscal quarter in which Registrable Securities
are sold to underwriters in a firm commitment or best efforts underwritten
offering and (ii) if not sold to underwriters in such an offering, commencing on
the first day of the first fiscal quarter of the Company after the effective
date of a Registration Statement, which statements shall cover said 12-month
periods.

         (p) Use its reasonable best efforts to cooperate with each seller of
Registrable Securities covered by any Registration Statement and each
underwriter, if any, participating in the disposition of such Registrable
Securities and their respective counsel in connection with any filings required
to be made with the National Association of Securities Dealers, Inc. (the

                                     - 12 -
<PAGE>

"NASD"), including, if the Conduct Rules of the NASD or any successor thereto as
amended from time to time so require, engaging, at the underwriters' (or
Holders') expense, a "qualified independent underwriter" ("QIU") as contemplated
therein and making Records available to such QIU as though it were a
participating underwriter for the purposes of Section 4(m) and otherwise
applying the provisions of this Agreement to such QIU (including
indemnification) as though it were a participating underwriter.

         (q) Cause the Indenture to be qualified under the TIA not later than
the effective date of the first Registration Statement relating to the
Registrable Securities; and in connection therewith, cooperate with the Trustee
and the Holders of the Registrable Securities to effect such changes to the
Indenture as may be required for the Indenture to be so qualified in accordance
with the terms of the TIA; and execute, and use its reasonable best efforts to
cause the Trustee to execute, all documents as may be required to effect such
changes and all other forms and documents required to be filed with the SEC to
enable the Indenture to be so qualified in a timely manner.

         (r) Use its reasonable best efforts to take all other steps reasonably
necessary or advisable to effect the registration of the Registrable Securities
covered by a Registration Statement contemplated hereby.

         The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Company the Notice
and Questionnaire attached to the Final Memorandum dated January 12, 2004 used
in connection with the offer of the Convertible Notes and such other information
regarding such seller and the distribution of such Registrable Securities as the
Company may, from time to time, reasonably request to the extent necessary or
advisable to comply with the Securities Act. The Company may exclude from such
registration for the Registrable Securities any Seller who unreasonably fails to
furnish such information within a reasonable time after receiving such request
and, in such event, shall have no further obligation under this Agreement
(including, without limitation, under Section 3 hereof) with respect to such
Seller or any subsequent Holder of Registrable Securities. Each seller as to
which any Shelf Registration is being effected agrees to furnish promptly to the
Company all information required to be disclosed so that the information
previously furnished to the Company by such seller is not materially misleading
and does not omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances under which they were made.

         Each Holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon actual receipt of any notice from the Company
of the happening of any event of the kind described in Section 4(c)(ii),
4(c)(iii) or 4(c)(iv) hereof, or upon the suspension of the availability of the
Registration Statement or any Prospectus pursuant to Section 3(b), such Holder
will forthwith discontinue disposition of such Registrable Securities covered by
such Registration Statement or Prospectus until such Holder's receipt of the
copies of the supplemented or amended Prospectus contemplated by Section 4(k)
hereof, or until it is advised in writing by the Company that the use of the
applicable Prospectus may be resumed and has received copies of any amendments
or supplements thereto.

5.       Registration Expenses.

counsel retained by or on behalf of the underwriters and transfer taxes, if any,
related to the sale or disposition of such Holder's securities.

         (b) The Company shall reimburse the Holders of the Registrable
Securities being registered in a Shelf Registration for the reasonable fees and

be designated pursuant to this Section 5(b).

6. Indemnification. The Company agrees to indemnify and hold harmless (i) each
Initial Purchaser, (ii) each Holder, (iii) each Person, if any, who controls

Registrable Securities is registered (or any amendment thereto) or any related
Prospectus or any amendment or supplement thereto or any related preliminary
Prospectus, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein in the light of the circumstances under which they were made not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with information relating to
any Holder furnished to the Company in writing by or on behalf of such Holder
expressly for use in therein; provided, however, that the Company shall not be
liable to any Indemnified Holder under the indemnity agreement of this paragraph
with respect to any preliminary Prospectus to the extent that any such loss,
claim, damage, liability, judgment or expense of such Indemnified Holder results
from the fact that such Indemnified Holder sold Registrable Securities under a
Registration Statement to a Person as to whom it shall be established that there
was not sent or given, at or prior to the written confirmation of such sale, a
copy of the Prospectus (or of the preliminary Prospectus as then amended or
supplemented if the Company shall have furnished such Indemnified Holder with
such amendment or supplement thereto on a timely basis), and the loss, claim,
damage, liability or expense of such Indemnified Holder results from an untrue
statement or omission of a material fact contained in the preliminary Prospectus
which was corrected in the Prospectus (or in the preliminary Prospectus as then
amended or supplemented if the Company shall have furnished such Indemnified
Holder with such amendment or supplement thereto, as the case may be, on a
timely basis).

                  Each Holder agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, officers and each Person who
controls the Company within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act to the same extent as the foregoing
indemnity from the Company to each Holder, but only (i) with reference to
information relating to a Holder furnished to the Company in writing by or on
behalf of such Holder expressly for use in any Registration Statement or
Prospectus, any amendment or supplement thereto or any related preliminary
Prospectus or (ii) with respect to any untrue statement or representation made
by such Holder in writing to the Company.

                  If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such Person (the "Indemnified Person") shall promptly
notify the Person or Persons against whom such indemnity may be sought (each an
"Indemnifying Person") in writing of the commencement thereof. However, the
failure so to notify the Indemnifying Person (i) will not relieve it from
liability hereunder unless and to the extent it did not otherwise learn of such
action and such failure results in the forfeiture by the Indemnifying Person of
substantial rights and defenses and (ii) will not, in any event, relieve the
Indemnifying Person from any obligations to any Indemnified Person other than
the indemnification obligation provided hereunder. The Indemnifying Person shall
be entitled to participate in such action and, to the extent that it shall wish,
jointly with any other Indemnifying Person similarly notified, to assume the
defense thereof, with counsel reasonably satisfactory to the Indemnified Person
(in which case the Indemnifying Person shall not thereafter be responsible for
the fees and expenses of any separate counsel retained by the Indemnified Person
or Persons except as set forth below).

                                     - 15 -
<PAGE>

Notwithstanding the Indemnifying Person's election to assume the defense and
employ counsel in an action, an Indemnified Person shall have the right to
employ separate counsel (including local counsel) and the Indemnifying Person
shall bear the reasonable fees, costs and expenses of such separate counsel if
(i) the use of counsel chosen by the Indemnifying Person to represent the
Indemnified Person would present such counsel with a conflict of interest, (ii)
the actual or potential defendants in, or targets of, any such action include
both the Indemnified Person and the Indemnifying Person and the Indemnified
Person shall have reasonably concluded that there may be legal defenses
available to it and/or other Indemnified Persons which are different from or
additional to those available to the Indemnifying Person, (iii) the Indemnifying
Person shall have failed to assume the defense and employ counsel reasonably
satisfactory to the Indemnified Person within a reasonable time after notice of
the institution of such action or (iv) the Indemnifying Person shall authorize
the Indemnified Person to employ separate counsel at the expense of the
Indemnifying Person. The Indemnifying Person shall not be liable for any
settlement of any proceeding effected without its prior written consent, but if
settled with such consent or if there be a final judgment for the plaintiff for
which the Indemnified Person is entitled to indemnification pursuant to this
Agreement, such Indemnifying Person agrees to indemnify and hold harmless any
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment. No Indemnifying Person shall, without the prior written
consent of the Indemnified Person, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnity could have been sought hereunder by such
Indemnified Person, unless such settlement (A) includes an unconditional written
release of such Indemnified Person from all liability on claims that are the
subject matter of such proceeding and (B) does not include any statement as to
an admission of fault, culpability or failure to act by or on behalf of any
Indemnified Person.

                  If the indemnification provided for in the first and second
paragraphs of this Section 6 is unavailable to an Indemnified Person or
insufficient in respect of any losses, claims, damages or liabilities referred
to therein, then each Indemnifying Person under such paragraph, in lieu of
indemnifying such Indemnified Person thereunder, shall contribute to the amount
paid or payable by such Indemnified Person as a result of such losses, claims,
damages or liabilities (i) in such proportion as is appropriate to reflect the
relative benefits received by the Indemnifying Person on the one hand and the
Indemnified Person on the other hand pursuant to the Purchase Agreement or from
the offering of Convertible Notes or (ii) if the allocation provided by clause
(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Indemnifying Person on the one hand and
the Indemnified Person on the other in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations. The relative benefits received
by the Company on the one hand and any Indemnified Holder on the other shall be
deemed to be in the same proportion as the total net proceeds from the initial
offering and sale of Convertible Notes (before deducting expenses) received by
the Company bear to the total net proceeds received by such Indemnified Holder
from sales of Registrable Securities giving rise to such obligations. The
relative fault of the parties shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or such Indemnified Holder and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

<PAGE>

                  Each of the Company and the Initial Purchasers agrees that it
would not be just and equitable if contribution pursuant to this Section 6 were
determined by pro rata allocation or by any other method of allocation that does
not take account of the equitable considerations referred to in the immediately
preceding paragraph. The amount paid or payable by an Indemnified Person as a
result of the losses, claims, damages and liabilities referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any reasonable legal or other expenses actually
incurred by such Indemnified Person in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this
Section 6, in no event shall any Holder be required to contribute any amount in
excess of the amount by which proceeds received by such Holder from the sale of
the Registrable Securities pursuant to a Shelf Registration Statement exceeds
the amount of damages which such Holder would have otherwise been required to
pay or has paid by reason of such untrue or alleged untrue statement or omission
or alleged omission. No Person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

                  The remedies provided for in this Section 6 are not exclusive
and shall not limit any rights or remedies that may otherwise be available to
any indemnified party at law or in equity.

                  The indemnity and contribution agreements contained in this
Section 6 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Holder or any Person controlling any Holder or by or on behalf of the
Company, its officers or directors or any other Person controlling any of the
Company and (iii) acceptance of and payment for any of the Registrable
Securities.

7. Rules 144 and 144A. The Company covenants that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations adopted by the SEC thereunder in a timely manner in
accordance with the requirements of the Securities Act and the Exchange Act and,
for so long as any Registrable Securities remain outstanding, if at any time the
Company is not required to file such reports, it will, upon the request of any
Holder or beneficial owner of Registrable Securities, make available such
information necessary to permit sales pursuant to Rule 144A under the Securities
Act. The Company further covenants that, for so long as any Registrable
Securities remain outstanding, it will use its reasonable best efforts to take
such further action as any Holder of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such holder to
sell Registrable Securities without registration under the Securities Act within
the limitation of the exemptions provided by (a) Rule 144(k) and Rule 144A under
the Securities Act, as such rules may be amended from time to time, or (b) any
similar rule or regulation hereafter adopted by the SEC. Notwithstanding the
foregoing, nothing in this Section 7 shall be deemed to require the Company to
register any of its securities pursuant to the Exchange Act.

8.       Underwritten Registrations.

         If any of the Registrable Securities covered by any Shelf Registration
are to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will manage the offering will be selected
by the Holders of the majority in Amount of

                                     - 17 -
<PAGE>

Registrable Securities to be included in such offering and be reasonably
acceptable to the Company.

         No Holder of Registrable Securities may participate in any underwritten
registration hereunder unless such Holder (a) agrees to sell such Holder's
Registrable Securities on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

9.       Miscellaneous.

         (a) No Inconsistent Agreements. The Company has not, as of the date
hereof, and the Company shall not, after the date of this Agreement, enter into
any agreement with respect to any of its securities that is inconsistent with
the rights granted to the Holders of Registrable Securities in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Company's other issued and outstanding
securities under any such agreements. The Company has not entered and will not
enter into any agreement with respect to any of its securities that will grant
to any Person piggy-back registration rights with respect to a Registration
Statement.

         (b) Adjustments Affecting Registrable Securities. Except in compliance
with Section 9(c), the Company shall not knowingly, directly or indirectly, take
any action with respect to the Registrable Securities as a class that would
adversely affect the ability of the Holders of Registrable Securities to include
such Registrable Securities in a Shelf Registration undertaken pursuant to this
Agreement.

         (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, otherwise than with the prior written
consent of the Company and the Holders of not less than a majority in Amount of
Registrable Securities. Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders of Registrable Securities whose securities
are being sold pursuant to a Registration Statement and that does not directly
or indirectly affect, impair, limit or compromise the rights of other Holders of
Registrable Securities may be given by Holders of at least a majority in Amount
of Registrable Securities being sold by such Holders pursuant to such
Registration Statement. Each Holder of Registrable Securities outstanding at the
time of any such amendment, modification, supplement, waiver or consent or
thereafter shall be bound by any such amendment, modification, supplement,
waiver or consent effected pursuant to this Section 9(c), whether or not any
notice, writing or marking indicating such amendment, modification, supplement,
waiver or consent appears on the Registrable Securities or is delivered to such
Holder. Each Holder may waive compliance with respect to any obligation of the
Company under this Agreement as it may apply or be enforced by such particular
Holder.

         (e) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties hereto,
including the Holders; provided, however, that this Agreement shall not inure to
the benefit of or be binding upon a successor or assign of a Holder unless and
except to the extent such successor or assign holds Registrable Securities.

         (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken

this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and

hereto shall use their reasonable best efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
