         SECTION 1.03. COMPLIANCE CERTIFICATES AND OPINIONS. Upon any
application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee an
Officers' Certificate stating that all conditions precedent, if any, provided
for in this Indenture relating to the proposed action have been complied with
and an Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

                  (a) a statement that each individual signing such certificate
or opinion has read such condition or covenant and the definitions herein
relating thereto;

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

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

                  (d) a statement as to whether, in the opinion of each such
individual, such condition or covenant has been complied with.

         SECTION 1.04. FORM OF DOCUMENTS DELIVERED TO TRUSTEE. In any case where
several matters are required to be certified by, or covered by an opinion of,
any specified Person, it is not necessary that all such matters be certified by,
or covered by the opinion of, only one such Person, or that they be so certified
or covered by only one document, but one such Person may certify or give an
opinion as to some matters and one or more other such Persons as to other
matters, and any such Person may certify or give an opinion as to such matters
in one or several documents.

                                     -9-
<PAGE>

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon an Opinion of Counsel, or a
certificate or representations by counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the opinion, certificate or
representations with respect to the matters upon which such certificate or
opinion is based are erroneous. Any such Opinion of Counsel or certificate or
representations may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Company stating that the information as to such factual matters is in the
possession of the Company, unless such counsel knows that the certificate or
opinion or representations as to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         SECTION 1.05. ACTS OF HOLDERS.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of the Outstanding Securities, may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such Holders in
person or by agents duly appointed in writing. Except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"ACT" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent, or of the
holding by any Person of a Security, shall be sufficient for any purpose of this
Indenture and conclusive in favor of the Trustee and the Company and any agent
of the Trustee or the Company, if made in the manner provided in this Section
1.05.

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

                  (c) The ownership of the Securities shall be proved by the
Security Register.

                  (d) (i) If the Company shall solicit from the Holders any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at its option, in or pursuant to a Board Resolution, fix in
advance a record date for the determination of Holders entitled to effect such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so; provided that the Company
shall not be entitled to set a

                                 -10-
<PAGE>

record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or
direction referred to in clause 1.05(d)(iii) below. Notwithstanding TIA
Section 316(c), such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not earlier than the
date 30 days prior to the first solicitation of Holders generally in
connection therewith and not later than the date such solicitation is
completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be
effected before or after such record date, but only the Holders of record at
the close of business on such record date shall be deemed to be Holders for
the purposes of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; provided that no such authorization, agreement or consent
by the Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than
eleven months after the record date.

                           (ii)  Subject to clause 1.05(d)(iii) below, in the
absence of any such record date fixed by the Company, regardless as to whether
any solicitation of the Holders is occurring on behalf of the Company or any
Holder, the Trustee may, at its option, fix in advance a record date for the
determination of such Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Trustee
shall have no obligation to do so. Any such record date shall be a date not more
than 30 days prior to the first solicitation of Holders generally in connection
therewith and no later than the date of such solicitation.

                           (iii) The Trustee may set any day as a record date
for the purpose of determining the Holders of Outstanding Securities entitled
to join in the giving or making of (A) any notice of default, (B) any
declaration of acceleration referred to in Section 4.02, (C) any request to
institute proceedings referred to in Section 4.07(b), or (D) any direction
referred to in Section 4.12 and may also set an expiration date by which the
relevant Act must be taken. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Securities on such record date, and no
other Holders, shall be entitled to join in such notice, declaration, request
or direction, whether or not such Holders remain Holders after such record
date; provided that no such Act shall be effective hereunder unless taken on
or prior to any applicable expiration date by Holders of the requisite
principal amount of Outstanding Securities on such record date. Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action (whereupon the record date previously set shall
automatically and without any action by any Person be canceled and of no
effect), nor shall anything in this paragraph be construed to render
ineffective any Act taken by Holders of the requisite principal amount of
Outstanding Securities on the date such Act is taken. Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company's
expense, shall cause notice of such record date, the proposed Act by Holders
and the applicable expiration date to be given to the Company in writing and
to each Holder of Outstanding Securities in the manner set forth in Section
1.07.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder

                                 -11-
<PAGE>

of every Security issued upon the registration of transfer thereof or in
exchange therefor or in lieu thereof in respect of anything done, omitted or
suffered to be done by the Trustee, any Security Registrar, any Paying Agent,
any Conversion Agent or the Company in reliance thereon, whether or not
notation of such action is made upon such Security.

         SECTION 1.06. NOTICES, ETC. to Trustee and Company. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other notice or communication provided or permitted by this Indenture to be made
upon, given or furnished to, or filed with:

                  (a) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee, delivered in person, mailed by first class mail,
postage prepaid, or sent by facsimile (and receipt confirmed by a Responsible
Officer over the telephone) or overnight courier, at its Corporate Trust Office,
Attention: Corporate Trust Administration (TriQuint Semiconductor, Inc. 4%
Convertible Subordinated Notes due 2007); PROVIDED that notices or other
communications to the Trustee shall only be deemed given when actually received
by the Trustee,

                  (b) the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and delivered in person, mailed by first class mail,
postage prepaid, or sent by facsimile or overnight courier, to the Company
addressed to it at the address of its principal office specified in the first
paragraph of this Indenture; provided that the Company may, by notice furnished
in writing to the Trustee, designate additional or different addresses for
subsequent notices or communications by the Company.

         SECTION 1.07. NOTICE TO HOLDERS; WAIVER. Where this Indenture provides
for notice of any event to Holders by the Company or the Trustee, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to each such Holder affected by
such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders given as provided herein. Any notice mailed to a Holder
in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

         If by reason of the suspension of or irregularities in regular mail
service or by reason of any other cause it shall be impracticable to give such
notice by mail, then such notification to Holders as shall be made with the
approval of the Trustee shall constitute a sufficient notification to such
Holders for every purpose hereunder.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

                                    -12-
<PAGE>

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

         SECTION 1.08. EFFECT OF HEADINGS AND TABLE OF CONTENTS. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

         SECTION 1.09. SUCCESSORS AND ASSIGNS. All covenants and agreements in
this Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

         SECTION 1.10. SEPARABILITY CLAUSE. In case any provision in this
Indenture or in any Security shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

         SECTION 1.11. BENEFITS OF INDENTURE. Nothing in this Indenture or in
the Securities, express or implied, shall give to any Person, other than the
parties hereto, any Security Registrar, any Paying Agent, any Conversion Agent
and their successors hereunder and the Holders any benefit or any legal or
equitable right, remedy or claim under this Indenture.

         SECTION 1.12. GOVERNING LAW. This Indenture and the Securities shall be
governed by and construed in accordance with the law of the State of New York
without regard to conflicts of laws principles.

         SECTION 1.13. LEGAL HOLIDAYS. In any case where any Interest Payment
Date, Redemption Date, Repurchase Date, Stated Maturity or Maturity of any
Security or the last date on which a Holder has the right to convert his
Securities shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or any Security), payment
of Redemption Price, Repurchase Price, interest (including Liquidated Damages,
if any) or principal (and premium, if any), or conversion of the Securities,
need not be made at such Place of Payment on such date, but may be made on the
next succeeding Business Day at such Place of Payment with the same force and
effect as if made on the Interest Payment Date, Redemption Date, Repurchase Date
or at the Stated Maturity or Maturity or on such last day for conversion;
provided that no interest shall accrue on the amount so payable for the period
from and after such Interest Payment Date, Redemption Date, Repurchase Date,
Stated Maturity or Maturity or on such last day for conversion, as the case may
be.

         SECTION 1.14. PERSONAL IMMUNITY FROM LIABILITY FOR INCORPORATORS,
STOCKHOLDERS, ETC. No recourse shall be had for the payment of the principal of
or premium, if any, or interest (including Liquidated Damages), if any, on any
Security, or for any claim based thereon, or otherwise in respect of any
Security, or based on or in respect of this Indenture or any indenture
supplemental hereto, against any incorporator, or against any past, present or
future stockholder, director or officer, as such, of the Company or of any
successor corporation, whether by virtue of

                                  -13-
<PAGE>

any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being expressly waived
and released as a condition of, and as consideration for, the execution of
this Indenture and the issue of Securities.

         SECTION 1.15. CONFLICT WITH TRUST INDENTURE ACT. If any provision
hereof limits, qualifies or conflicts with a provision of the TIA that is
required under such Act to be a part of and govern this Indenture, the latter
provision shall control. If any provision of this Indenture modifies or excludes
any provision of the TIA that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be. To the extent that any provision of a Security
conflicts with a provision in this Indenture, the provision of this Indenture
shall control.

                                SECURITIES FORMS

         SECTION 2.01. FORMS OF SECURITIES. The Securities shall be in
substantially the form of Exhibit A hereto, and shall have notations, legends or
endorsements required by law, stock exchange rule or usage or as otherwise
indicated in Exhibit A hereto.

         SECTION 2.02.     FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION.

         The Trustee's certificate of authentication shall be in substantially
the following form:

         This is one of the Securities described in the within-mentioned
Indenture.

DATED:                                   STATE STREET BANK AND TRUST COMPANY OF
                                         CALIFORNIA, N.A.
                                           as Trustee

                                         By:
                                            ------------------------------------

         SECTION 2.03. SECURITIES ISSUABLE IN GLOBAL FORM. Except as otherwise
provided in this Section 2.03 or in Section 3.04, the Securities shall be
issuable only in global form and deposited with the Trustee, at its Corporate
Trust Office, as custodian for DTC or the nominees thereof, and any such
Security shall represent such of the Outstanding Securities as shall be set
forth in the books and records of the Trustee and may provide that it shall
represent the aggregate amount of Outstanding Securities from time to time as
adjusted in the books and records of the Trustee, and that the aggregate amount
of Outstanding Securities represented thereby may from time to time be increased
or decreased to reflect exchanges. Any adjustment of the aggregate amount of
Outstanding Securities represented by a Security in global form shall be made by
the Trustee in such manner and upon instructions given by such Person or Persons
as shall be specified therein or in the Company Order to be delivered to the
Trustee pursuant to Section 3.03. Subject to the provisions of Section 3.03, the
Trustee shall deliver and redeliver any Security in global form in the manner
and

                                    -14-
<PAGE>

upon instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 3.03 has been,
or simultaneously is, delivered, any instructions by the Company with respect to
endorsement or delivery or redelivery of a Security in global form shall be in
writing but need not comply with Section 1.03 and need not be accompanied by an
Opinion of Counsel.

         The provisions of the last sentence of Section 3.03 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 1.03 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 3.03.

         Notwithstanding the provisions of Section 3.07, payment of principal of
and any premium and interest (including Liquidated Damages, if any) on any
Security in global form shall be made to the Person or Persons specified in such
Security.

         All Securities issued in global form shall bear the following legend:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), NEW YORK, NEW
YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR
IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC, AND
ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF DTC, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL BECAUSE THE REGISTERED OWNER
HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

         TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN
WHOLE, BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR
SUCH SUCCESSOR'S NOMINEE.

                                 The Securities

         SECTION 3.01. TITLE AND TERM. The Securities shall be and are hereby
authorized to be designated as "4% Convertible Subordinated Notes due 2007",
limited in aggregate principal amount to $300,000,000 (up to $345,000,000 if the
option set forth in Section 2(b) of the Purchase Agreement dated February 17,
2000 among the Company and the Initial Purchasers, is exercised in full). The
Securities shall mature and the principal thereof shall be due and payable,
together with

                                       -15-
<PAGE>

all accrued and unpaid interest thereon, on March 1, 2007. The Securities
shall be convertible into shares of Common Stock.

         SECTION 3.02. DENOMINATIONS. The Securities shall be issuable in
denominations of $1,000 and any integral multiple thereof.

         SECTION 3.03. EXECUTION, AUTHENTICATION, DELIVERY AND DATING. The
Securities shall be executed on behalf of the Company by the Chief Executive
Officer, Chief Financial Officer, the President or a Vice President of the
Company. The signature of any of these individuals on the Securities may be a
manual or facsimile signature of such authorized officer and may be imprinted or
otherwise reproduced on the Securities.

         Securities bearing the manual or facsimile signatures of an individual
who was at any time the proper officer of the Company shall bind the Company,
notwithstanding that such individual shall have ceased to hold such office prior
to the authentication and delivery of such Securities or did not hold such
office at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities, executed by the Company, to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for in Section
2.02, duly executed by the Trustee by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 3.08 together with a written statement (which need not comply with
Section 1.03 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of
this Indenture, such Security shall be deemed not to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this
Indenture.

         SECTION 3.04. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE. The
Company shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency of the Company in a Place of Payment a register for the
Securities (the "SECURITY REGISTER") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of the Securities and of transfers of the Securities. The Security Register
shall be in written form or any other form capable of being converted into
written form within a reasonable time. The Trustee, at its Corporate Trust
Office, is hereby appointed "SECURITY REGISTRAR" for the purpose of registering
the Securities and transfers of the Securities on such Security Register as

                                    -16-
<PAGE>

herein provided. In the event that the Trustee shall cease to be Security
Registrar, it shall have the right to examine the Security Register at all
reasonable times.

         Subject to the provisions of this Section 3.04 and except as otherwise
provided in any Security, including any legend thereon, upon surrender for
registration of transfer of any Security at any office or agency of the Company
in a Place of Payment, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities, of any authorized denominations and of
a like aggregate principal amount, bearing a number not contemporaneously
outstanding, and containing identical terms and provisions.

         Subject to the provisions of this Section 3.04, at the option of the
Holder, the Securities may be exchanged for other Securities, of any authorized
denomination or denominations and of a like aggregate principal amount,
containing identical terms and provisions, upon surrender of the Securities to
be exchanged at any such office or agency. Whenever any such Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities that the Holder making the exchange is
entitled to receive.

         Notwithstanding the foregoing, any global Security shall be
exchangeable only as provided in this paragraph. The depositary for the global
Securities shall be DTC, and the global Securities may be transferred, in whole
but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to
a successor to DTC for such global Security selected or approved by the Company
or to a nominee of such successor to DTC. If at any time DTC notifies the
Company that it is unwilling or unable to continue as depositary for the
applicable global Security or Securities or if at any time DTC ceases to be a
clearing agency registered under the Securities Exchange Act of 1934 if so
required by applicable law or regulation, the Company shall appoint a successor
depositary with respect to such global Security or Securities. If (x) a
successor depositary for such global Security or Securities is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such unwillingness, inability or ineligibility, or (y) an Event of
Default has occurred and is continuing and the beneficial owners representing a
majority in principal amount of the applicable Securities represented by such
global Security or Securities advise DTC to cease acting as depositary for such
global Security or Securities, or (z) the Company, in its sole discretion,
executes and delivers to the Trustee and the Security Registrar an Officers'
Certificate stating that definitive Securities may be issued in exchange for
interests in a global Security or Securities, then the Company shall execute,
and the Trustee shall authenticate and deliver, definitive Securities of like
rank, tenor and terms in definitive form, registered in such names as DTC shall
direct and bearing such legends as the Company shall specify, in an aggregate
principal amount equal to the principal amount of such global Security or
Securities. If a Security is issued in exchange for any portion of a global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such Security,
but will be payable on such Interest Payment Date or proposed date for payment,
as the case may be, only to the Person to

                                     -17-
<PAGE>

whom interest in respect of such portion of such global Security is payable
in accordance with the provisions of this Indenture.

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

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

         No service charge shall be made to a Holder for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 8.06, 10.07, 11.03(e), or 12.02 not involving
any transfer.

         The Company or the Trustee, as applicable, shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security is
among those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
10.03 and ending at the close of business on the day of the mailing of the
relevant notice of redemption, or (ii) to register the transfer of or exchange
any Security so selected for redemption in whole or in part, except, in the case
of any Security to be redeemed in part, the portion thereof not to be redeemed,
or (iii) to issue, register the transfer of or exchange any Security that has
been surrendered for repayment at the option of the Holder, except the portion,
if any, of such Security not to be so repaid.

                  (a) Every Security that bears or is required under this
Section 3.04(a) to bear the legend set forth in this Section 3.04(a) (together
with any Common Stock issued upon conversion or exchange of the Securities
(including any exchange constituting payment of the Repurchase Price for
Securities pursuant to Article 11) and required to bear the legend set forth in
Section 3.04(b), collectively, the "RESTRICTED SECURITIES") shall be subject to
the restrictions on transfer set forth in this Section 3.04(a) (including one of
the legends set forth below), unless such restrictions on transfer shall be
waived by written consent of the Company, and the holder of each such Restricted
Security, by such holder's acceptance thereof, agrees to be bound by all such
restrictions on transfer. As used in Sections 3.04(a) and 3.04(b), the term
"transfer" encompasses any sale, pledge, transfer or other disposition
whatsoever of any Restricted Security.

         Until two years after the original issuance date of any Security, any
certificate evidencing such Security (and all securities issued in exchange
therefor or upon payment of the Repurchase Price therefor pursuant to Article
11, or substitution thereof, other than Common Stock, if any, issued upon
conversion thereof which shall bear the legend set forth in SECTION 3.04(b), if
applicable) shall bear a legend in substantially the following form (unless such
Securities have been transferred pursuant to a registration statement that has
been declared effective under the Securities

                                  -18-
<PAGE>

Act (and which continues to be effective at the time of such transfer),
pursuant to the exemption from registration provided by Rule 144 under the
Securities Act, or unless otherwise agreed by the Company in writing, with
notice thereof to the Trustee):

         THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE
FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT IT
IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE
SECURITIES ACT); (2) AGREES THAT IT WILL NOT WITHIN TWO YEARS AFTER THE ORIGINAL
ISSUANCE OF THE SECURITY EVIDENCED HEREBY RESELL OR OTHERWISE TRANSFER THE
SECURITY EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH
SECURITY EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED
INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C)
PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT (IF AVAILABLE) OR (D) 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); AND (3) AGREES THAT IT WILL DELIVER TO
EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A
TRANSFER PURSUANT TO CLAUSE 2(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF
THIS LEGEND. IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 2(C) ABOVE, THE
HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO STATE STREET BANK AND TRUST
COMPANY OF CALIFORNIA, N.A., AS TRUSTEE, SUCH CERTIFICATIONS, LEGAL OPINIONS OR
OTHER INFORMATION AS THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH
TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT
SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND
WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE SECURITY EVIDENCED
HEREBY PURSUANT TO CLAUSE 2(C) OR 2(D) ABOVE OR THE EXPIRATION OF TWO YEARS FROM
THE ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY.

         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 may, upon surrender of such Security for exchange to the Security
Registrar in accordance with the provisions of this Section 3.04, 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 3.04(a).

         Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in this Section 3.04(a)), the global Security 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.

                                   -19-
<PAGE>

         At such time as all interests in the global Security have been
redeemed, converted, canceled, repurchased or transferred, the global Security
shall be, upon receipt thereof, canceled by the Trustee in accordance with
standing procedures and instructions existing between the depositary and the
Custodian.

                  (b) Until two years after the original issuance date of any
Security, any stock certificate representing Common Stock issued upon conversion
or exchange of such Security (including any exchange constituting payment of the
Repurchase Price for any Securities pursuant to Article 11) of such Security
shall bear a legend in substantially the following form (unless such Common
Stock has been sold pursuant to the exemption from registration provided by Rule
144 under the Securities Act or 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 or exchange of Securities that have been transferred pursuant to
a registration statement that has been declared effective under the Securities
Act, or unless otherwise agreed by the Company with written notice thereof to
the Trustee (in the form of an Officers' Certificate) and any transfer agent for
the Common Stock):

         THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE
U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE
FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES THAT UNTIL THE EXPIRATION OF TWO
YEARS AFTER THE ORIGINAL ISSUANCE OF THE NOTE UPON THE CONVERSION OR EXCHANGE OF
WHICH THE COMMON STOCK EVIDENCED HEREBY WAS ISSUED, (1) IT WILL NOT RESELL OR
OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT (A) TO THE COMPANY
OR ANY SUBSIDIARY THEREOF, (B) TO A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED
IN RULE 144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C) IN
ACCORDANCE WITH THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT (IF AVAILABLE), OR (D) IN ACCORDANCE WITH A REGISTRATION
STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH
CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (2) PRIOR TO ANY SUCH
TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 1(D) ABOVE), IT WILL FURNISH
TO CHASEMELLON SHAREHOLDER SERVICES L.L.C., AS TRANSFER AGENT, SUCH
CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY MAY
REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT WILL DELIVER TO EACH PERSON TO
WHOM THE COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER
PURSUANT TO CLAUSE 1(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS
LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE
COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE 1(C) OR 1(D) ABOVE OR THE
EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE SECURITY

<PAGE>

UPON THE CONVERSION OR EXCHANGE OF WHICH THE COMMON STOCK EVIDENCED HEREBY
WAS ISSUED.

         Any such Common Stock as to which such restrictions on transfer shall
have expired in accordance with their terms may, upon surrender of the
certificates representing such shares of Common Stock for exchange in accordance
with the procedures of the transfer agent for the Common Stock, be exchanged for
a new certificate or certificates for a like aggregate number of shares of
Common Stock, which shall not bear the restrictive legend required by this
SECTION 3.04(b).

                  (c) 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 that results in
such Securities or Common Stock, as the case may be, no longer being "restricted
securities" (as defined under Rule 144).

                  (d) Notwithstanding any provision of Section 3.04 to the
contrary, in the event Rule 144(k) as promulgated under the Securities Act (or
any successor rule) is amended to change the two-year period under Rule 144(k)
(or the corresponding period under any successor rule), from and after receipt
by the Trustee of the Officers' Certificate and Opinion of Counsel provided for
in this Section 3.04(d), (i) each reference in Section 3.04(a) to "two years"
and in the restrictive legend set forth in such paragraph to "TWO YEARS" shall
be deemed for all purposes hereof to be references to such changed period, (ii)
each reference in Section 3.04(b) to "two years" and in the restrictive legend
set forth in such paragraph to "TWO YEARS" shall be deemed for all purposes
hereof to be references to such changed period and (iii) all corresponding
references in the Securities and the restrictive legends thereon shall be deemed
for all purposes hereof to be references to such changed period, provided that
such changes shall not become effective if they are otherwise prohibited by, or
would otherwise cause a violation of, the then-applicable federal securities
laws. As soon as practicable after the Company has knowledge of the
effectiveness of any such amendment to change the two-year period under Rule
144(k) (or the corresponding period under any successor rule), unless such
changes would otherwise be prohibited by, or would otherwise cause a violation
of, the then-applicable securities law, the Company shall provide to the Trustee
an Officers' Certificate and Opinion of Counsel informing the Trustee of the
effectiveness of such amendment and the effectiveness of the foregoing changes
to Sections 3.04(a) and 3.04(b) and the Notes. The provisions of this Section
3.04(d) shall not be effective until such time as the Opinion of Counsel and
Officers' Certificate have been received by the Trustee hereunder. This Section
3.04(d) shall apply to successive amendments to Rule 144(k) (or any successor
rule) changing the holding period thereunder.

         SECTION 3.05. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If any
mutilated Security is surrendered to the Trustee or the Company, together with
such security or indemnity as may be required by the Company or the Trustee to
save each of them or any agent of either of them

                                     -21-

<PAGE>

harmless, the Company shall, at the relevant Holder's expense, execute and
the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same principal amount, containing identical terms and
provisions and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company, at the relevant Holder's expense, shall execute, and
upon the Company's request the Trustee shall authenticate and deliver, in lieu
of any such destroyed, lost or stolen Security, a new Security of the same
principal amount, containing identical terms and provisions and bearing a number
not contemporaneously outstanding, appertaining to such destroyed, lost or
stolen Security.

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

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

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

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

         SECTION 3.06. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. Interest
on any Security that is payable, and is punctually paid or duly provided for, on
any Interest Payment Date shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest at the office or agency of
the Company maintained for such purpose pursuant to Section 9.02; PROVIDED,
HOWEVER, that each installment of interest on any Security may at the Company's
option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 3.07, to the
address of such Person as it appears on the Security Register or (ii)
transferring to an account maintained by the payee located inside the United
States if the Trustee shall have received written bank wire instructions prior
to the Regular Record Date for such payment; PROVIDED, HOWEVER, that payments to
DTC shall be made by wire transfer of immediately available funds to the account
of DTC or its nominee. The term "REGULAR RECORD DATE" with

                                     -22-

<PAGE>

respect to any Interest Payment Date shall mean the February 15 or August 15
preceding March 1 or September 1, respectively.

         Any interest (including Liquidated Damages, if any) on any Security
that is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "DEFAULTED INTEREST") shall forthwith cease
to be payable to the registered Holder thereof on the relevant Regular Record
Date by virtue of having been such Holder, and such Defaulted Interest may be
paid by the Company, at its election in each case, as provided in clause 3.06(a)
or 3.06(b) below:

                  (a) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Securities (or their respective
Predecessor Securities) are registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest, which shall be fixed in
the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security and the date
of the proposed payment (which shall not be less than 30 days after such notice
is received by the Trustee) and at the same time the Company shall deposit with
the Trustee an amount of money equal to the aggregate amount proposed to be paid
in respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit on or prior to the date of the proposed payment,
such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this clause provided. Thereupon the
Company shall fix a Special Record Date for the payment of such Defaulted
Interest which shall be not more than 15 days and not less than 10 days prior to
the date of the proposed payment. The Company shall promptly notify the Trustee
of such Special Record Date and, in the name and at the expense of the Company,
the Trustee shall cause notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor to be mailed, first-class postage
prepaid, to each Holder of Securities at his address as it appears in the
Security Register not less than 10 days prior to such Special Record Date. The
Trustee may, in its discretion, in the name and at the expense of the Company,
cause a similar notice to be published at least once in an Authorized Newspaper
in each Place of Payment, but such publications shall not be a condition
precedent to the establishment of such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor
having been mailed as aforesaid, such Defaulted Interest shall be paid to the
Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following clause (b).

                  (b) The Company may make payment of any Defaulted Interest on
the Securities in any other lawful manner not inconsistent with the requirements
of any securities exchange on which such Securities may be listed, and upon such
notice as may be required by such exchange, if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

         SECTION 3.07. PERSONS DEEMED OWNERS. Prior to due presentment of a
Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any), and (subject to Sections 3.04 and 3.06)
interest on, such Security and for all other purposes whatsoever, whether or not
such Security is overdue, and neither the Company, the Trustee nor any agent of
the Company or the Trustee shall be affected by notice to the contrary.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar shall have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

         Notwithstanding the foregoing, with respect to any global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such global Security or impair, as between such depositary and owners of
beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its
nominee) as Holder of such global Security.

         SECTION 3.08. CANCELLATION. All Securities surrendered for payment,
redemption, repayment at the option of the Holder or registration of transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee, and any such Securities surrendered directly to the
Trustee for any such purpose shall be promptly canceled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder that the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder that the Company has not issued and sold, and all
Securities so delivered shall be promptly canceled by the Trustee. If the
Company shall so acquire any of the Securities, however, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are surrendered to the Trustee for
cancellation. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. Canceled Securities held by the Trustee shall be
destroyed by the Trustee and the Trustee shall deliver a certificate of such
destruction to the Company, unless by a Company Order the Company directs their
return to it.

         SECTION 3.09. COMPUTATION OF INTEREST. Interest (including Liquidated
Damages, if any) on the Securities shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.

         SECTION 3.10. CUSIP NUMBERS. The Company in issuing the Securities
shall use "CUSIP" numbers, and the Trustee shall use CUSIP numbers in notices of
redemption as a convenience to Holders; PROVIDED HOWEVER, that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any

                                     -24-

<PAGE>

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 shall promptly notify the Trustee of any change in the CUSIP numbers.

registered or certified mail, 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 a written notice specifying such default or breach and
requiring it to be remedied and stating that such notice is a "NOTICE OF
DEFAULT" hereunder; or

                  (f) a default under any bonds, debentures, notes or other

instruments under which there may be issued or by which there may be secured
or evidenced any indebtedness for money borrowed by the Company, whether such
indebtedness now exists or shall hereafter be created, which indebtedness,
individually or in the aggregate, has a principal amount outstanding in
excess of $35,000,000, which default shall have resulted in such indebtedness
becoming or being declared due and payable prior to the date on which it
would otherwise have become due and payable, without such indebtedness having
been discharged, or such acceleration having been rescinded or annulled,
within a period of 60 days after there shall have been given, by registered
or certified mail, 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 Securities
then Outstanding, a written notice specifying such default and requiring the
Company to cause such indebtedness to be discharged or cause such

         SECTION 4.02. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an
Event of Default with respect to Securities at the time Outstanding occurs and
is continuing, then and in every such case the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities may declare the
principal of all the Securities, and accrued interest thereon to the date of
such declaration, to be due and payable immediately, by a notice in writing to
the Company (and to the Trustee if given by the Holders), and upon any such
declaration such principal shall become immediately due and payable. If an Event
of Default specified in Section 4.01(g) or Section 4.01(h) occurs, the principal
of, and accrued interest on, all the Securities shall automatically, and without
any declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable.

         At any time after such a declaration of acceleration with respect to
the Securities has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter provided in this
Article, the Holders of a majority in principal amount of the Outstanding
Securities, by written notice to the Company and the Trustee, may rescind and
annul such declaration and its consequences if:

                  (a) the Company has paid or deposited with the Trustee a sum
sufficient to pay:

                           (i) all overdue installments of interest on all
Outstanding Securities,

                           (ii) the principal of (and premium, if any, on) any
Outstanding Securities that have become due otherwise than by reason of such
declaration of acceleration and interest thereon at the rate or rates borne by
or provided for in such Securities,

                           (iii) to the extent that payment of such interest is
lawful, interest upon overdue installments of interest at the rate or rates
borne by or provided for in such Securities, and

                           (iv) all sums paid or advanced by the Trustee
hereunder and the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel; and

                  (b) all Events of Default with respect to the Securities,
other than the nonpayment of the principal of (or premium, if any) or interest
on Securities which have become due solely by reason of such declaration of
acceleration, have been cured or waived as provided in Section 4.13.

         No such rescission shall affect any subsequent Event of Default or
impair any right in respect thereof.

         SECTION 4.03. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE. The Company covenants that if:

                  (a) default is made in the payment of any installment of
interest on any Security when such interest becomes due and payable and such
default continues for a period of 30 days, or

                                     -27-

<PAGE>

                  (b) default is made in the payment of the principal of (or
premium, if any, on) any Security at its Maturity,

         then the Company shall, upon demand of the Trustee, pay to the Trustee,
for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal (and premium, if any) and interest,
with interest upon any overdue principal (and premium, if any) and, to the
extent that payment of such interest shall be legally enforceable, upon any
overdue installments of interest, if any, at the rate or rates borne by or
provided for in such Securities, and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

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

         If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

         SECTION 4.04. TRUSTEE MAY FILE PROOFS OF CLAIM. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Securities under a supplemental
indenture entered into in accordance herewith or the property of the Company or
of such other obligor or the Company's, or any such other obligor's, creditors,
the Trustee (irrespective of whether the principal of the Securities shall then
be due and payable as therein expressed or by acceleration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue principal, premium, if any, or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise:

                  (a) to file and prove a claim for the whole amount, or such
lesser amount as may be provided for in the Securities, of principal (and
premium, if any) and interest, owing and unpaid in respect of the Securities and
to file such 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 of the Holders allowed in such judicial proceeding, and

                  (b) to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same;

                                     -28-

<PAGE>

         and any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby directed by each Holder to make such payments to the Trustee, and in the
event that the Trustee shall request or consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee and
any predecessor Trustee, their agents and counsel, and any other amounts due the
Trustee or any predecessor Trustee under Section 5.07.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a
Security, any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder of a Security in any
such proceeding; PROVIDED HOWEVER, that the Trustee may, on behalf of the
Holders, vote for the election of a trustee in bankruptcy or similar official
and be a member of a creditors' or other similar committee.

         SECTION 4.05. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES. All rights of action and claims under this Indenture or any of the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

         SECTION 4.06. APPLICATION OF MONEY COLLECTED. Any money collected by
the Trustee pursuant to this Article shall be applied in the following order, at
the date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium, if any) or interest, upon
presentation of the Securities, or both, as the case may be, and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

         FIRST: To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 5.07;

         SECOND: To the holders of Senior Indebtedness to the extent required by
the provisions of Article 13.

         THIRD: To the payment of the amounts then due and unpaid upon the
Securities for principal (and premium, if any) and interest (including
Liquidated Damages, if any) payable, in respect of which or for the benefit of
which such money has been collected, ratably, without preference or priority of
any kind, according to the aggregate amounts due and payable on such Securities
for principal (and premium, if any) and, interest (including Liquidated Damages,
if any), respectively; and

         FOURTH:  To the payment of the remainder, if any, to the Company.

                                     -29-

<PAGE>

         SECTION 4.07. LIMITATION ON SUITS. No Holder of any Security shall have
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

                  (a) such Holder has previously given written notice to the
Trustee of a continuing Event of Default with respect to the Securities;

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

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

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

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

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

         SECTION 4.08. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
PREMIUM, IF ANY, AND INTEREST. Notwithstanding any other provision in this
Indenture, the Holder of any Security shall have the right, which is absolute
and unconditional, to receive payment of the principal of, and premium, if any,
including the Redemption Prices and Make-Whole Payment upon redemption pursuant
to Article 10, the Repurchase Price pursuant to Article 11 and (subject to
Sections 3.04 and 3.06) interest (including Liquidated Damages, if any) on such
Security on the respective due dates expressed in such Security (or, in the case
of redemption or repurchase, on the Redemption Date or Repurchase Date, as the
case may be) and to convert such Security in accordance with the provisions of
this Indenture and to institute suit for the enforcement of any such payment and
right to convert, and such rights shall not be impaired without the consent of
such Holder.

         SECTION 4.09. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or any
Holder of a Security has instituted any proceeding to enforce any right or
remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, the Company, the Trustee and the
Holders of Securities shall, subject to any determination in such proceeding, be
restored severally

                                     -30-
<PAGE>

and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

         SECTION 4.10. 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 3.05, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders of
Securities 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 4.11. DELAY OR OMISSION NOT WAIVER. No delay or omission of the
Trustee or of any Holder of any Security to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities, as the case may be.

         SECTION 4.12. CONTROL BY HOLDERS OF SECURITIES. The Holders of not less
than a majority in principal amount of the Outstanding Securities shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the Securities, PROVIDED that:

                  (a) such direction shall not be in conflict with any rule of
law or with this Indenture,

                  (b) the Trustee may take any other action deemed proper by the
Trustee that is not inconsistent with such direction, and

                  (c) the Trustee need not take any action that might involve it
in personal liability or be unduly prejudicial to the Holders of Securities not
joining therein.

         SECTION 4.13. WAIVER OF PAST DEFAULTS. The Holders of not less than a
majority in principal amount of the Outstanding Securities may on behalf of the
Holders of all the Securities waive any past Default or Event of Default
hereunder with respect to such Securities and its consequences, except a Default
or Event of Default:

                  (a) in the payment of the principal of (or premium, if any) or
interest on any Security,

                  (b) in respect of the conversion by the Company of any
Security into Common Stock,

                                     -31-
<PAGE>

                  (c) in the payment of the Redemption Prices or Make-Whole
Payment pursuant to Article 10,

                  (d) in the payment of the Repurchase Price pursuant to Article
11, or

                  (e) in respect of a covenant or provision hereof that under
Article 8 cannot be modified or amended without the consent of the Holder of
each Outstanding Security affected.

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

         SECTION 4.14. WAIVER OF USURY, STAY OR EXTENSION LAWS. The Company
covenants (to the extent that it may lawfully do so) that it shall not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but shall suffer and permit the execution
of every such power as though no such law had been enacted.

         SECTION 4.15. UNDERTAKING FOR COSTS. All parties to this Indenture
agree, and each Holder of any Security by his acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, 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, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit
having due regard to the merits and good faith of the claims or defenses made
by such party litigant; but the provisions of this Section shall not apply to
any suit instituted by the Trustee, to any suit instituted by the Company, to
any suit instituted by any Holder, or group of Holders, holding in the
aggregate more than 10% in principal amount of the Outstanding Securities, or
to any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest on any Security on or after the
respective Stated Maturities expressed in such Security (or, in the case of
redemption or repurchase, on or after the Redemption Date or the Repurchase
Date, respectively), or the right to convert any Security in accordance with
ARTICLE 12.

                                    ARTICLE 5
                                   THE TRUSTEE

         SECTION 5.01. GENERAL. The Trustee, prior to the occurrence of an Event
of Default and after the curing of all Events of Default that may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default has occurred (that has not
been cured or waived) the Trustee shall exercise such of the rights and

                                     -32-
<PAGE>

powers vested in it by this Indenture, and use the same degree of care and
skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.

         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, its own willful misconduct, its own recklessness or its own bad faith.

         SECTION 5.02. CERTAIN RIGHTS OF TRUSTEE. Subject to TIA Sections 15(a)
through (d):

                  (a) the Trustee may rely, and shall be protected in acting or
refraining from acting, upon any resolution, certificate, statement, instrument,
facsimile transmission, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, other evidence of indebtedness or other paper or
document believed by it to be genuine and to have been signed, made or presented
by, the proper person and may accept and rely upon the same as conclusive
evidence of the truth and accuracy of the statements and opinions contained
therein. The Trustee need not investigate any fact or matter stated in any such
document;

                  (b) before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel, which shall conform
to Section 1.03. 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 consult with counsel, and the written
advice of such counsel shall be full and complete authorization and protection
with respect to any action taken, suffered or omitted by it hereunder in good
faith and in reliance thereon, and may act through its attorneys and agents and
shall not be responsible for the misconduct or negligence of any attorney or
agent appointed with due care;

                  (d) the Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders, unless such Holders shall have offered to the
Trustee reasonable security or indemnity against the costs, expenses and
liabilities that might be incurred by it in complying with such request or
direction;

                  (e) the Trustee shall not be liable for any action it takes or
omits to take in good faith that it believes to be authorized or within its
rights or powers or for any action it takes or omits to take in accordance with
the written direction of the holders of a majority in principal amount of the
Outstanding Securities relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee, under this Indenture;

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

                                     -33-
<PAGE>

                  (g) 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;

                  (h) the Trustee shall not be required to take notice or be
deemed to have notice of any Default or Event of Default hereunder unless a
Responsible Officer of the Trustee be specifically notified of such Default or
Event of Default in writing by the Company or any Holder, and in the absence of
such notice the Trustee may conclusively assume that there is no Default or
Event of Default; provided that if the Trustee is acting as Paying Agent, the
Trustee shall be required to take and be deemed to have notice of its failure to
receive payments of interest or principal hereunder;

                  (i) except for information provided by the Trustee concerning
the Trustee, the Trustee shall have no responsibility with respect to any
information in any offering memorandum or other disclosure material distributed
with respect to the Securities, and the Trustee shall have no responsibility for
compliance with securities laws in connection with the issuance and sale, resale
or exchange of the Securities;

                  (j) in the event the Trustee shall receive inconsistent or
conflicting requests and indemnity from two or more groups of Holders, each
representing at least 25% (but less than 50%) of the aggregate principal amount
of the Securities then Outstanding, the Trustee shall act in accordance with
instructions received by the Holders of the greater percentage thereof;

                  (k) except as otherwise expressly provided by the provisions
of this Indenture, the Trustee shall not be obligated and may not be required to
give or furnish any notice, demand, report, request, reply, statement, advice or
opinion to any Holder or to the Company or any other Person, and the Trustee
shall not incur any liability for its failure or refusal to give or furnish the
same unless obligated or required to do so by the express provisions hereof; and

                  (l) the Trustee shall not be required to give any bond or
surety with respect to the performance of its duties or the exercise of its
powers under this Indenture.

         SECTION 5.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee, any Paying
Agent, Security Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Securities and may
otherwise deal with the Company, its Subsidiaries or its Affiliates with the
same rights it would have if it were not the Trustee, Paying Agent, Security
Registrar or such other agent. Any registrar, co-registrar, paying agent,
conversion agent or authenticating agent may do the same with like rights.
However, upon qualification of this Indenture under the TIA the Trustee shall be
subject to TIA Sections 310(b) and 311.

                                     -34-

         SECTION 5.04. TRUSTEE'S DISCLAIMER. The Trustee (i) makes no
representation as to the validity or adequacy of this Indenture or the
Securities, (ii) shall not be accountable for the Company's use or application
of the proceeds from the Securities and (iii) shall not be responsible for any
statement in the Securities other than its certificate of authentication.

         SECTION 5.05. NOTICE OF DEFAULT. If any Event of Default occurs and is
continuing and if the Trustee has actual knowledge of such Event of Default, the
Trustee shall mail to each holder in the manner and to the extent provided in
TIA Section 313(c) notice of the Event of Default within 90 days after it
occurs, unless such Event of Default has been cured or waived; PROVIDED,
HOWEVER, that, except in the case of a Default in the payment of the principal
of (or premium, if any) or interest on any Security, the Trustee shall be
protected in withholding such notice if and so long as Responsible Officers of
the Trustee in good faith determine that the withholding of such notice is in
the interests of the Holders of the Securities; and provided further that in the
case of any Default or breach referred to in Section 4.01(e) with respect to the
Securities, no such notice to Holders shall be given until at least 60 days
after the occurrence thereof.

         SECTION 5.06. CONFLICTING INTERESTS OF TRUSTEE. If the Trustee has or
shall acquire a conflicting interest within the meaning of the TIA, the Trustee
shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of the TIA and this Indenture.

         SECTION 5.07. COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee such compensation as shall be agreed upon in writing for its services.
The compensation of the Trustee shall not be limited by any law on compensation
of a trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses, disbursements and advances
incurred or made by the Trustee in accordance with this Indenture. Such expenses
shall include the reasonable compensation, expenses, disbursements and advances
of the Trustee's agents and counsel.

         The Company shall indemnify and hold harmless the Trustee and its
officers, directors, agents and employees (collectively the "INDEMNITEES")
against any and all losses, liabilities, obligations, damages, penalties, fines,
judgments, actions, suits, proceedings, reasonable costs and expenses (including
reasonable fees and disbursements of counsel) of any kind whatsoever that may be
incurred by or imposed on the Indemnitees or any of them arising out of or in
connection with the acceptance or administration of the Trustee's duties under
this Indenture; PROVIDED, HOWEVER, that the Company need not reimburse any
expense or indemnify against any loss, obligation, damage, penalty, fine,
judgment, action, suit, proceeding, reasonable cost or expense (including
reasonable fees and disbursements of counsel) of any kind whatsoever that may be
incurred by Indemnitees or any of them which results from the negligence or
willful misconduct of the Indemnitees or any of them. The Trustee shall notify
the Company promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Company shall not relieve the Company of its
obligations hereunder, unless the Company is materially prejudiced thereby. The
Company shall defend the claim and the Trustee shall cooperate in the defense.
Unless otherwise set forth herein, the Indemnitees, or any of them, may have
separate counsel and the Company shall pay the

                                     -35-
<PAGE>

reasonable fees and expenses of such counsel. The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably
withheld. The provisions of this Section 5.07 shall survive the termination of
this Indenture and the resignation or removal of the Trustee for any reason.

         To secure the Company's payment obligations in this Section 5.07, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee, in its capacity as Trustee, except money or
property held in trust to pay principal of, premium, if any, and interest on
particular Securities.

         If the Trustee incurs expenses or renders services after the occurrence
of an Event of Default specified in Section 4.01(g) or Section 4.01(h), such
expenses, and the compensation due to the Trustee for such services, are
intended to constitute expenses of administration under Title 11 of the United
States Bankruptcy Code or any applicable federal or state law for the relief of
debtors.

         SECTION 5.08. REPLACEMENT OF TRUSTEE. A resignation or removal of the
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section
5.08.

         The Trustee may resign at any time by so notifying the Company in
writing at least thirty days prior to the date of the proposed resignation. At
any time, the Holders of a majority in principal amount of the Outstanding
Securities may, by written notice to the Trustee and the Company, remove the
Trustee and, with the prior consent of the Company, appoint a successor Trustee.
The Company may remove the Trustee if: (i) the Trustee is no longer eligible
under Section 5.10; (ii) the Trustee is adjudged a bankrupt or an insolvent;
(iii) a receiver or other public officer takes charge of the Trustee or its
property; or (iv) the Trustee becomes incapable of acting.

         If the Trustee is removed without the concurrent appointment by the
Holders of a successor Trustee, if the Trustee resigns, or if a vacancy exists
in the office of Trustee for any other reason, the Company shall promptly
appoint a successor Trustee. If no successor Trustee has delivered its written
acceptance required by the next succeeding paragraph of this Section 5.08 within
thirty days after the retiring Trustee delivers notice of its resignation or is
removed, or after the occurrence of a vacancy in the office of Trustee for any
other reason, the retiring Trustee, the Company or the Holders of a majority in
principal amount of the Outstanding Securities may petition any court of
competent jurisdiction for 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 the
delivery of such written acceptance, subject to payment of all amounts due and
owing to the Trustee under Section 5.07 and its lien provided in Section 5.07,
(i) the retiring Trustee shall transfer all property held by it as Trustee to
the successor Trustee, (ii) the resignation or removal of the retiring Trustee
shall become effective and (iii) the successor Trustee 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 Holder.

                                     -36-
<PAGE>

         If the Trustee is no longer eligible under Section 5.10, any Holder who
satisfies the requirements of TIA Section 310(b) may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee.

         The Company shall give notice of any resignation and any removal of the
Trustee and each appointment of a successor Trustee to all holders. Each notice
shall include the name of the successor Trustee and the address of its Corporate
Trust Office.

         Notwithstanding replacement of the Trustee pursuant to this Section
5.08, the Company's obligations under Section 5.07 shall continue for the
benefit of the retiring Trustee.

         SECTION 5.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business (including the administration of this
Indenture) to, another corporation or national banking association, the
resulting, surviving or transferee corporation or national banking association,
without any further act, shall be the successor Trustee with the same effect as
if the successor Trustee had been named as the Trustee herein.

         SECTION 5.10. ELIGIBILITY. This Indenture shall always have a Trustee
who satisfies the requirements of TIA Section 310(a)(1). The Trustee (or the
bank holding company to which the Trustee is a member) shall have a combined
capital and surplus of at least $25 million as set forth in its most recent
published annual report of condition.

         SECTION 5.11. MONEY HELD IN TRUST. Subject to the provisions of Section
9.03 and Sections 13.02, 13.03, 13.09 all monies received by the Trustee shall,
until used or applied as herein provided, be held in trust for the purposes for
which they were received. The Trustee shall not be liable for interest on any
money received by it except as the Trustee may agree 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 5.12. PREFERENTIAL COLLECTION OF CLAIMS. If and when the
Trustee shall be or become a creditor of the Company (or any other obligor upon
the Securities under a supplemental indenture entered into in accordance
herewith), the Trustee shall be subject to the provisions of the Trust Indenture
Act regarding the collection of the claims against the Company (or any such
other obligor).

         SECTION 5.13. TRUSTEE'S APPLICATION FOR INSTRUCTIONS FROM THE COMPANY;
LIQUIDATED DAMAGES. Any application by the Trustee for written instructions from
the Company (other than with regard to any action proposed to be taken or
omitted to be taken by the Trustee that affects the rights of the Holders or
holders of Senior Indebtedness under this Indenture, including, without
limitation, under Article 13 hereof) may, at the option of the Trustee, set
forth in writing any action proposed to be taken or omitted by the Trustee under
this Indenture and the date on and/or after which such action shall be taken or
such omission shall be effective. The Trustee shall not be liable for any action
taken by, or omission of, the Trustee in accordance with a proposal included in
such application on or after the date specified in such application (which date
shall not be less than ten

                                     -37-
<PAGE>

Business Days after the date any officer of the Company actually receives such
application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

                  (a) If Liquidated Damages are payable to Holders pursuant to
the terms of the Registration Rights Agreement, the Company shall deliver to the
Trustee a certificate to that effect stating (i) the amount of Liquidated
Damages that is payable and (ii) the date on which such amount of Liquidated
Damages is payable. Unless and until a Responsible Officer of the Trustee
receives at the Corporate Trust Office such a certificate, the Trustee may
assume without inquiry that no such Liquidated Damages are payable. Upon receipt
of a Company Request together with a sum sufficient to pay such Liquidated
Damages so becoming due, the Trustee shall pay such Liquidated Damages to the
Holders in the same manner as interest on the Securities. If the Company has
paid Liquidated Damages directly to the Persons entitled to them, the Company
shall deliver to the Trustee a certificate setting forth the particulars of such
payment.

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

         SECTION 6.01. DISCLOSURE OF NAMES AND ADDRESSES OF HOLDERS. Every
Holder of Securities, by receiving and holding the same, agrees with the Company
and the Trustee that neither the Company or the Trustee, nor any Paying Agent or
any Security Registrar shall be held accountable by reason of the disclosure of
any information as to the names and addresses of the Holders of Securities in
accordance with TIA Section 312, regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under TIA Section
312(b).

         SECTION 6.02. REPORTS BY TRUSTEE. Within 60 days after May 15 of each
year, commencing with the first May 15 after the qualification of this
Indenture, the Trustee shall transmit by mail to all Holders of Securities as
provided in TIA Section 313(c), if required by TIA Section 313(a), a brief
report dated as of such May 15. A copy of each such report shall at the time of
such transmission to Holders be filed by the Trustee with the Company.

         SECTION 6.03. REPORTS BY COMPANY. The Company shall:

                  (a) file with the Trustee, within 15 days after the Company is
required to file the same with the Commission, copies of the annual reports and

any of the foregoing as the Commission may from time to time by rules and
regulations prescribe) that the Company may be required to file with the
Commission pursuant to Sections 13(a) or 13(b) or Section 15(d) of the
Securities Exchange Act of 1934; or, if the Company is not required to file
information, documents or reports pursuant to any of such Sections, then it
shall file with the Trustee, in accordance with rules and regulations prescribed
from time to time by the Commission, such of the supplementary and periodic
information, documents

                                     -38-

and transmit by mail to the Holders, within thirty days after the filing
thereof with the Trustee, in the manner and to the extent provided in TIA

Section as may be required by rules and regulations prescribed from time to

         SECTION 6.04. COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF
HOLDERS.

                  (a) The Company shall furnish or cause to be furnished to the

                CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

         SECTION 7.01. CONSOLIDATIONS AND MERGERS OF COMPANY AND SALES, LEASES
AND CONVEYANCES PERMITTED SUBJECT TO CERTAIN CONDITIONS. The Company may
consolidate with or merge into or transfer or lease its assets substantially as
an entirety to any Person, and any Person is entitled to consolidate with or
merge into, or transfer or lease its assets substantially as an entirety to the
Company, PROVIDED HOWEVER, that in any such case, (1) either the Company shall
be the continuing corporation, or the Person (if other than the Company) formed
by such consolidation or

                                     -39-
<PAGE>

into which the Company is merged, or the Person (if other than a Subsidiary of
the Company) that receives the Company's assets substantially as an entirety,
is a corporation, partnership, limited liability company or trust organized and
existing under the laws of any United States jurisdiction and expressly assumes
the due and punctual payment of the principal of and premium, if any (including
the Make-Whole Payment, if any), and any interest (including Liquidated
Damages, if any) payable pursuant to this Indenture on all of the Securities,
according to their tenor, and the due and punctual performance and observance
of all of the covenants and conditions of this Indenture to be performed by the
Company and shall have provided for conversion rights, if applicable, in
accordance with the provisions of Article 12 hereof, by supplemental indenture,
complying with Article 8 hereof, satisfactory to the Trustee, executed and
delivered to the Trustee by such entity and (2) immediately after giving effect
to such consolidation, merger, transfer or lease, no Default or Event of
Default, shall have happened and be continuing. For purposes of the foregoing,
the transfer (by lease, assignment, sale or otherwise) of the properties and
assets of one or more Subsidiaries (other than to the Company or another
Subsidiary), which, if such assets were owned by the Company, would constitute
all or substantially all of the properties and assets of the Company, shall be
deemed to be the transfer of all or substantially all of the properties and
assets of the Company.

         SECTION 7.02. RIGHTS AND DUTIES OF SUCCESSOR CORPORATION. In case of
any such consolidation, merger, sale, lease, conveyance or other disposition and
upon any such assumption by the successor Person, such successor Person shall
succeed to and be substituted for the Company, with the same effect as if it had
been named herein as the party of the first part, and the predecessor
corporation, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities. Such successor Person
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Company, any or all of the Securities issuable hereunder that
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor Person, instead of the Company,
and subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver any Securities that
previously shall have been signed and delivered by the officers of the Company
to the Trustee for authentication, and any Securities that such successor Person
thereafter shall cause to be signed and delivered to the Trustee for that
purpose. All the Securities so issued shall in all respects have the same legal
rank and benefit under this Indenture as the Securities theretofore or
thereafter issued in accordance with the terms of this Indenture as though all
of such Securities had been issued at the date of the execution hereof.

         In case of any such consolidation, merger, sale, lease, conveyance or
other disposition, such changes in phraseology and form (but not in substance)
may be made in the Securities thereafter to be issued as may be appropriate.

         SECTION 7.03. OFFICERS' CERTIFICATE AND OPINION OF COUNSEL. Any
consolidation, merger, sale, lease, transfer, conveyance or other disposition
permitted under Section 7.01 is also subject to the condition that the Trustee
receive an Officers' Certificate and an Opinion of Counsel to the effect that
any such consolidation, merger, sale, lease, transfer or conveyance or other
disposition, complies with the provisions of this Article and constitutes the
legal, valid and binding obligation of the successor Person, subject to
customary enforceability exceptions.

Holders; PROVIDED, HOWEVER, that in respect of any such additional Events of
Default such supplemental indenture may provide for a particular period of grace
after default (which period may be shorter or longer than that allowed in the
case of other defaults) or may provide for an immediate enforcement upon such
default or may limit the remedies available to the Trustee upon such default or
may limit the right of the Holders of a majority in aggregate principal amount
of those Securities to which such additional Events of Default apply to waive
such default;

                  (d) to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee and to add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee;

Commission in connection with the qualification of the Indenture under TIA; or

                  (h) to provide for the issuance of uncertificated Securities
in addition to or in place of certificated Securities; PROVIDED, HOWEVER that
the uncertificated Securities are issued in registered form for purposes of
Section 163(f) of the Internal Revenue Code of 1986.

         SECTION 8.02. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS. With the
consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities affected

and the Trustee, the Company, when authorized by or pursuant to a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of
modifying in any manner the rights of the Holders; PROVIDED, HOWEVER, that no
such supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

                  (a) reduce the principal amount, Repurchase Price or
Redemption Price with respect to any Security, or extend the Stated Maturity of
any Security or alter the manner of payment or rate of interest on any Security

and their consequences);

                  (c) make any change that adversely affects the right to
convert any Security;

                  (d) modify the provisions of the Indenture relating to the
ranking of the Securities in a manner adverse to the Holders of the Securities;
or

                  (e) impair the right to institute suit for the enforcement of
any payment with respect to, or conversion of, the Securities.

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

         SECTION 8.03. EXECUTION OF SUPPLEMENTAL INDENTURE. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Article 5)
shall be fully protected in relying upon, an Opinion of Counsel stating that (i)
the execution of such supplemental indenture is authorized or permitted by this
Indenture, (ii) all conditions precedent to its execution and delivery have been

binding obligation of the Company. The Trustee may, but shall not be obligated
to, enter into any such supplemental indenture that affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.

         SECTION 8.05. CONFORMITY WITH TRUST INDENTURE ACT. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act as then in effect.

         SECTION 8.06. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.
Securities authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall, if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture. If the Company shall so determine, new Securities
so modified as to conform, in the opinion of the Trustee and the Company, to any
such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities.

                                    ARTICLE 9
                                    COVENANTS

         SECTION 9.01. PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST. The
Company covenants and agrees for the benefit of the Holders of Securities that
it shall duly and punctually pay the principal of (and premium, if any),
interest (including Liquidated Damages, if any) on, and the Repurchase Price,
the Redemption Price and the Make-Whole Payment with respect to the Securities
in accordance with the terms of the Securities and this Indenture. At the option
of the Company, all payments of principal with respect to any Security may be
paid by check to the registered Holder of the Security or other Person entitled
thereto against surrender of such Security. The conversion of any Securities
pursuant to Article 12 hereof and payment of the Repurchase Price by delivery of
shares of Common Stock in accordance with Article 11, together with the making
of any cash payments required to be made in accordance with the terms of the
Securities and this Indenture, shall satisfy the Company's obligations under
this Section 9.01 with respect to such Securities.

         SECTION 9.02. MAINTENANCE OF OFFICE OR AGENCY. The Company shall
maintain a Place of Payment for the Securities in the Borough of Manhattan, The
City of New York, which shall be an office or agency where the Securities may be
presented or surrendered for payment or conversion, exchange or redemption,
where the Securities may be surrendered for registration of transfer or exchange
and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served. The office or agency of the Trustee
in the Borough of Manhattan, The City of New York, shall initially be such
office or agency of the Company, unless and until the Company shall designate
and maintain some other office or agency for one or more of such purposes. The
Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of each 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 its agent to receive all
such presentations, surrenders, notices and demands.

                                     -43-
<PAGE>

         The Company may from time to time designate one or more other offices
or agencies (in or outside of The City of New York) where the Securities may be
presented or surrendered for any or all of such purposes, and may from time to
time rescind such designations; PROVIDED, HOWEVER, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in accordance with the requirements set forth above for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

         SECTION 9.03. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST. If the
Company shall at any time act as its own Paying Agent with respect to any
Securities, it shall, on or before each due date of the principal of (and
premium, if any), or interest on, the Securities, segregate and hold in trust
for the benefit of the Persons entitled thereto a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
shall promptly notify the Trustee of its action or failure so to act.

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

         The Company shall cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument pursuant to which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section,
that such Paying Agent shall:

                  (a) hold all sums held by it for the payment of principal of
(and premium, if any,) or interest on the Securities, in trust for the benefit
of the Persons entitled thereto, until such sums shall be paid to such Persons
or otherwise disposed of as herein provided;

                  (b) give the Trustee notice of any default by the Company (or
any other obligor upon the Securities under a supplemental indenture entered
into in accordance herewith) in the making of any such payment of principal (and
premium, if any) or interest; and

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

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

                                     -44-
<PAGE>

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall be paid to the Company upon Company Request or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company
for payment of such principal of (and premium, if any) or interest on any
Security, without interest thereon, 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 an Authorized
Newspaper, 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, shall be
repaid to the Company.

         SECTION 9.04. EXISTENCE. Subject to Article 7, the Company shall do or
cause to be done all things necessary to preserve and keep in full force and
effect the corporate existence of the Company and its Subsidiaries, and their
respective rights (charter and statutory) and franchises, except to the extent
that the Board of Directors shall determine that the failure to do so would not
have a material adverse effect on the business, assets, financial condition or
results of operation of the Company (a "MATERIAL ADVERSE EFFECT"); PROVIDED,
HOWEVER, that the Company shall not be required to preserve any right or
franchise if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and
that the loss thereof is not disadvantageous in any material respect to the
Holders.

         SECTION 9.05. PAYMENT OF TAXES AND OTHER CLAIMS. The Company shall pay
or discharge, or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company or any Subsidiary and have a Material Adverse Effect; 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.

         SECTION 9.06. STATEMENT AS TO COMPLIANCE. The Company shall deliver to
the Trustee, within 120 days after the end of each fiscal year of the Company, a
certificate from the Company's Chief Executive Officer, Chief Financial Officer
or principal accounting officer as to his or her knowledge of the Company's
compliance with all terms, conditions and provisions under this Indenture and,
in the event of any noncompliance, specifying such noncompliance and the nature
and status thereof. For purposes of this Section 9.06, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

         SECTION 9.07. WAIVER OF CERTAIN COVENANTS. The Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 9.04 to 9.05,

                                     -45-
<PAGE>

inclusive, if, before the time for such compliance, the Holders of at least a
majority in principal amount of the Outstanding Securities, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or
condition shall remain in full force and effect.

         SECTION 9.08. RULE 144A INFORMATION REQUIREMENT. Within the period
prior to the expiration of the holding period applicable to sales thereof under
Rule 144(k) under the Securities Act (or any successor provision), the Company
covenants and agrees that it shall, during any period in which it is not subject
to Section 13 or 15(d) under the Exchange Act, make available to any Holder or
beneficial owner of Securities that continue to be Restricted Securities, in
connection with any sale thereof and any prospective purchaser of Securities
from such holder or beneficial owner, the information required pursuant to Rule
144A(d)(4) under the Securities Act upon the request of any such holder or
beneficial owner of the Securities and the Company shall take such further
action as any holder or beneficial owner of such Securities may reasonably
request, all to the extent required from time to time to enable such holder or
beneficial owner to sell its Securities without registration under the
Securities Act within the limitation of the exemption provided by Rule 144A, as
such rule may be amended from time to time.

                                   ARTICLE 10
                            REDEMPTION OF SECURITIES

         SECTION 10.01. PROVISIONAL AND OPTIONAL REDEMPTION BY THE COMPANY. (a)
The Securities may be redeemed at the election of the Company, as a whole or in
parts from time to time, at any time prior to March 5, 2003 (a "PROVISIONAL
REDEMPTION"), upon notice as set forth in Section 10.04, at a redemption price
equal to $1,000 per $1,000 principal amount of the Securities redeemed plus
accrued and unpaid interest (including Liquidated Damages), if any (such amount,
together with the Make-Whole Payment described below, the "PROVISIONAL
REDEMPTION PRICE"), to but excluding the date of redemption (the "PROVISIONAL
REDEMPTION DATE") if (i) the Closing Price of the Common Stock has exceeded 150%
of the Conversion Price (as defined in Article 12 and as such may be adjusted
from time to time) then in effect for at least 20 Trading Days within a period
of 30 consecutive Trading Days ending on the Trading Day prior to the date of
mailing of the provisional notice of redemption pursuant to Section 10.04 (the
"NOTICE DATE"), and (ii) a registration statement covering resales of the
Securities and the Common Stock issuable upon conversion thereof is effective
and available for use and is expected to remain effective for the 30 days
following the Provisional Redemption Date unless registration is no longer
required.

         Upon any such Provisional Redemption, the Company shall make an
additional payment in cash (the "MAKE-WHOLE PAYMENT") with respect to the
Securities called for redemption to holders on the Notice Date in an amount
equal to $166.67 per $1,000 principal amount of the Securities, less the amount
of any interest actually paid on such Securities prior to the date of
redemption. The Company shall make the Make-Whole Payment on all Securities
called for Provisional Redemption,

                                     -46-
<PAGE>

including those Securities converted into Common Stock between the Notice Date
and the Provisional Redemption Date.

                  (a) The Securities may be redeemed at the election of the
Company, as a whole or from time to time in part, at any time on or after March
5, 2003, and prior to maturity (an "OPTIONAL REDEMPTION"), upon notice as set
forth in Section 10.04, at the following optional redemption prices (expressed
as percentages of the principal amount), together in each case with accrued and
unpaid interest (including Liquidated Damages), if any, up to but not including
the date fixed for redemption (the "OPTIONAL REDEMPTION PRICE"), if redeemed
during the periods described below:

         March 1, 2006 through February 28, 2007                 100.571%.
</TABLE>

and 100% of the principal amount on March 1, 2007.

         SECTION 10.02. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of
the Company to redeem any Securities shall be evidenced by a Board Resolution.
In case of any redemption at the election of the Company of all or any part of
the Securities pursuant to Section 10.01 (Provisional Redemption or Optional
Redemption), the Company shall, at least 30 days prior to the giving of the
notice to the Holders of redemption in Section 10.04 (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of the Redemption Date
and of the principal amount of Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

         SECTION 10.03. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED. If
less than all the Securities are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 days and not less than 30 days prior
to the Redemption Date by the Trustee, from the Outstanding Securities not
previously called for redemption, by lot, pro rata or any other method that
complies with the requirements of any exchange on which the Securities are
listed or quoted and that as the Trustee shall deem fair and appropriate.

         If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed,
solely for purposes of determining the aggregate principal amount of the
Securities to be redeemed, to be the portion selected for redemption (PROVIDED,
HOWEVER, that the

                                     -47-
<PAGE>

Holder of such Security so converted and deemed redeemed shall not be entitled
to any interest payment as a result of such deemed redemption except for such
interest payment as such Holder would have otherwise been entitled to receive
upon conversion of such Security). Securities that have been converted during a
selection of Securities to be redeemed may be treated by the Trustee as
Outstanding for the purpose of such selection.

         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 integral
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.

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

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

         SECTION 10.04. NOTICE OF REDEMPTION. Notice of redemption shall be
given in the manner provided in Section 1.07 not less than 30 days nor more than
60 days prior to the Redemption Date in the case of an Optional Redemption or
Provisional Redemption; provided, in each case, that failure to give such notice
in the manner herein provided to the Holder of any Security designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other such Security or portion thereof.

         All notices of redemption shall state:

                  (a) the Redemption Date;

                  (b) the Redemption Price;

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

                  (d) if any Security is to be redeemed in part only, the
portion of the principal amount of each Security to be redeemed, and the notice
that relates to such Security shall state that on and after the Redemption Date,
upon surrender of such Security, the holder shall receive, without a charge, a
new Security or Securities of authorized denominations for the principal amount
thereof remaining unredeemed;

                                     -48-
<PAGE>

                  (e) that on the Redemption Date, the Redemption Price shall
become due and payable upon each such Security, or the portion thereof, to be
redeemed and, if applicable, that interest thereon shall cease to accrue on and
after said date;

                  (f) the Place or Places of Payment where such Securities are
to be surrendered for payment of the Redemption Price;

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

                  (h) the then current Conversion Price and Make-Whole Payment,
if any;

                  (i) that the Securities called for redemption may be converted
at any time before the close of business on the last Business Day prior to the
Redemption Date;

                  (j) the CUSIP number of such Security, if any; and

                  (k) that a Holder of Securities who desires to convert
Securities must satisfy the requirements for conversion contained in such
Securities.

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

         SECTION 10.05. DEPOSIT OF REDEMPTION PRICE. Not later than 11:00 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 is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 9.03) an amount of
money sufficient to pay, on the Redemption Date, the Redemption Price of all the
Securities or portions thereof that are to be redeemed on that date, other than
Securities or portions thereof called for redemption on that date that have been
delivered by the Company to the Trustee for cancellation or have been converted.
The Trustee or the Paying Agent, as the case may be, shall return to the Company
no later than 30 days after such request any money not required for that
purpose.

         SECTION 10.06. SECURITIES PAYABLE ON REDEMPTION DATE. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price) such Securities shall cease to
bear interest. Upon surrender of any such Security for redemption in accordance
with said notice, such Security shall be paid by the Company at the Redemption
Price; PROVIDED, HOWEVER, that if the Redemption Date is an Interest Payment
Date, the semi-annual payment of interest becoming due on such date shall be
payable to the Holders of such Securities registered as such on the relevant
Regular Record Date according to their terms and the provisions of Section 3.06,
and with respect to a Provisional Redemption, the holder of any Securities
converted into Common Stock pursuant to the terms hereof after the Notice Date
and prior to the Provisional Redemption Date shall have the right to the
Make-Whole Payment regardless of the conversion of such Securities.

                                     -49-
<PAGE>

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the Redemption Price, shall, until paid, bear
interest from the Redemption Date at the rate borne by the Security and such
Security shall remain convertible into Common Stock until the Redemption Price,
and any such accrued interest, shall have been paid or duly provided for.

         SECTION 10.07. SECURITIES REDEEMED IN PART. Any Security that is to be
redeemed only in part (pursuant to the provisions of this Article) shall be
surrendered at a Place of Payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing) and the Company shall execute and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge a new Security or Securities, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.

         SECTION 10.08. 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 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.
Notwithstanding anything to the contrary contained in this Article 10, the
obligation of the Company to pay the Redemption Price of such Securities shall
be deemed to be satisfied and discharged to the extent such amount is so paid by
such purchasers. If such an agreement is entered into, a copy of which shall be
filed with the Trustee prior to 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 12) surrendered by such purchasers for conversion, all as
of immediately prior to the close of business on 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
(including the Make-Whole Payment, if any, with respect to all Securities called
for Provisional Redemption). At the direction of the Company, the Trustee shall
hold and dispose of any such amount paid to it in the same manner as it would
monies deposited with it by the Company for the redemption of 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 to which the Trustee has not consented in writing, 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 5 hereof, including, but not
limited to, the right to indemnification pursuant to Section 5.07

                                     -50-

             REPURCHASE AT OPTION OF HOLDERS UPON CHANGE IN CONTROL

         SECTION 11.01. RIGHT TO REQUIRE REPURCHASE. In the event that a Change
in Control shall occur, each Holder shall have the right, at the Holder's
option, to require the Company to repurchase (subject to the provisions of
Section 13.03) all of such Holder's Securities, or any portion of the principal
amount thereof that is an integral multiple of $1,000 (provided that no single
Security may be repurchased in part unless the portion of the principal amount
of such Security to be outstanding after such repurchase is equal to $1,000 or
an integral multiple of $1,000), on the date (the "REPURCHASE DATE") that is 45
Business Days after the date of the occurrence of a Change in Control at a
purchase price equal to 100% of the principal amount plus interest (including
Liquidated Damages, if any) accrued and unpaid to the Repurchase Date (the
"REPURCHASE PRICE"). At the option of the Company, the Repurchase Price may be
paid in cash or, subject to the fulfillment by the Company of the conditions set
forth in Section 11.02, by delivery of that number of shares of Common Stock
equal to the quotient of (i) the Repurchase Price divided by (ii) 95% of the
average of the Closing Prices of the Common Stock for the five consecutive
Trading Days ending on and including the third Trading Day immediately preceding
the date of the occurrence of the Change in Control.

         SECTION 11.02. CONDITIONS TO THE COMPANY'S ELECTION TO PAY THE
REPURCHASE PRICE IN COMMON STOCK. The Company may elect to pay the Repurchase
Price by delivery of shares of Common Stock pursuant to Section 11.01 if and
only if the following conditions have been satisfied:

                  (a) The shares of Common Stock delivered in payment of the
Repurchase Price are listed for trading on a U.S. national securities exchange
or approved for trading in the Nasdaq National Market;

                  (b) The shares of Common Stock delivered in payment of the
Repurchase Price (i) shall not require registration under any federal securities
law before such shares may be freely transferable without being subject to any
transfer restrictions under the Securities Act upon repurchase pursuant to this
Article 11 or, if such registration is required, such registration shall be
completed and shall become effective prior to the Repurchase Date, and (ii)
shall not require registration with or approval of any governmental authority
under any state law or any other federal law before such shares may be validly
issued or delivered upon repurchase pursuant to this Article 11, or if such
registration is required or such approval must be obtained, such registration
shall be completed or such approval shall be obtained prior to the Repurchase
Date; and

                  (c) All shares of Common Stock delivered in payment of the
Repurchase Price are issued out of the Company's authorized but unissued Common
Stock and shall, upon issue, be duly and validly issued and fully paid and
non-assessable and free of any preemptive rights.

         If all of the conditions set forth in this Section 11.02 are not
satisfied in accordance with the terms hereof, the Repurchase Price shall be
paid by the Company only in cash.

         SECTION 11.03. NOTICES; METHOD OF EXERCISING REPURCHASE RIGHT, ETC.

                  (a) Unless the Company shall have theretofore called for
redemption all of the Outstanding Securities, on or before the date that is 30
Business Days after the occurrence of a Change in Control, the Company shall
give notice to all Holders of Outstanding Securities and to the Trustee (the
"COMPANY NOTICE") of the occurrence of the Change in Control and of the
repurchase right set forth herein arising as a result thereof.

         Each Company Notice shall state:

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

                           (ii) the date by which the Change in Control Purchase
Notice (as defined below) must be delivered;

                           (iii) the Repurchase Date;

                           (iv) the Repurchase Price, and whether the Repurchase
Price shall be paid by the Company in cash or by delivery of shares of Common
Stock;

                           (v) the name and address of the Paying Agent and the
Conversion Agent;

                           (vi) that Securities with respect to which a Change
in Control Purchase Notice is given by the Holder may be converted only if the
Change in Control Purchase Notice has been withdrawn in accordance with the
terms set forth herein;

                           (vii) a description of the procedure that a Holder
must follow to exercise a repurchase right;

                           (viii) the procedures for withdrawing a Change in
Control Purchase Notice;

                           (ix) the place or places where such Securities are to
be surrendered for payment of the Repurchase Price or for conversion;

                           (x) briefly, the conversion rights of Holders of
Securities;

                           (xi) the Conversion Rate and any adjustments thereto;
and

                           (xii) that Holders who want to convert Securities
must satisfy the requirements set forth in the Securities.

         The Company shall cause a copy of the Company Notice to be published in
The Wall Street Journal or another daily newspaper of national circulation.

                                     -52-

<PAGE>

         If any Senior Indebtedness is outstanding at the time of the occurrence
of a Change in Control, and such Senior Indebtedness prohibits by its terms the
Company's repurchase of its Securities upon the occurrence of a Change in
Control, the Company shall prior to giving the Company Notice either: (i) repay
in full all obligations and terminate all commitments under or in respect of all
such Senior Indebtedness; or (ii) offer to repay in full all obligations and
terminate all commitments under or in respect of all such Senior Indebtedness
and repay such Senior Indebtedness owed to each holder thereof who has accepted
such offer; or (iii) obtain the requisite consents under all such Senior
Indebtedness to permit the Company to repurchase the Securities in accordance
herewith.

                  (b) To exercise a repurchase right, a Holder must deliver to
the Trustee or a Paying Agent at an office or agency maintained by the Company
for such purpose in the Borough of Manhattan, The City of New York, prior to the
close of business on the Business Day prior to the Repurchase Date (i) written
notice of the Holder's exercise of such right (the "CHANGE IN CONTROL PURCHASE
NOTICE"), which notice shall set forth (A) the name of the Holder, (B) the
certificate numbers of the Securities with respect to which the repurchase right
is being exercised, (C) the principal amount of the Securities to be repurchased
(and, if any Security is to be repurchased in part, the portion of the principal
amount thereof to be repurchased, which shall be in integral multiples of
$1,000) and (D) a statement that an election to exercise the repurchase right is
being made thereby pursuant to the applicable provisions of the Securities and
(ii) surrender the Securities subject to the Change in Control Purchase Notice.

                  (c) Unless the Company has elected to pay the Repurchaser
Price by delivery of shares of Common Stock on or prior to the Repurchase Date,
the Company shall deposit with the Trustee or with the Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 9.03) an amount of money sufficient to pay the Repurchase
Price of the Securities that are to be repaid on the Repurchase Date. On the
Repurchase Date, the Trustee, a Paying Agent (or, if the Company is acting as
its own Paying Agent, the Company) shall repurchase all such Securities validly
tendered prior to such date.

         In the event that a Holder has previously delivered a Change in Control
Purchase Notice, but failed to surrender the Security with respect to which such
Change in Control Purchase Notice relates, then so long as either (i) the
Company has elected to pay the Repurchase Price by delivery of Shares of Commons
Stock or (ii) the Trustee or the Paying Agent holds (or, if the Company is
acting as its own Paying Agent, the Company segregates and holds in trust as
provided in Section 9.03) money sufficient to pay the Repurchase Price in
respect of such Security, then such Security shall cease to be Outstanding for
the purposes of this Indenture and all rights of the Holder thereof other than
the right to receive the Repurchase Price shall terminate on the Repurchase
Date.

                  (d) If any Security (or portion thereof) surrendered for
repurchase shall not have been repurchased on the Business Day following the
Repurchase Date, the Repurchase Price in respect of such Security shall, until
paid, bear interest from the Business Day following the Repurchase Date at the
rate borne by the Security and such Security shall remain convertible into

                                     -53-

<PAGE>

Common Stock until the Repurchase Price and any such accrued interest shall have
been paid or duly provided for.

                  (e) Any Security that is to be repurchased only in part shall
be surrendered to the Trustee or any such Paying Agent 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, containing
identical terms and conditions, each in an authorized denomination in aggregate
principal amount equal to and in exchange for the portion of the principal of
the Security so surrendered that was not repurchased.

                  (f) Any Holder that has delivered a Change in Control Purchase
Notice shall have the right to withdraw such notice by delivery of a written
notice of withdrawal to the Trustee or any such Paying Agent prior to the close
of business on the Business Day immediately preceding the Repurchase Date. The
notice of withdrawal shall state the principal amount and the certificate
numbers of the Securities as to which the withdrawal notice relates and the
principal amount, if any, that remains subject to the change in Control Purchase
Notice. A Security in respect of which a Holder has exercised its right to
require repurchase upon a Change in Control may thereafter be converted into
Common Stock only if, and at such time as, such Holder withdraws its Change in
Control Purchase Notice in accordance with the preceding sentence.

                  (g) Any issuance of shares of Common Stock in respect of the
Repurchase Price shall be deemed to have been effected immediately prior to the
close of business on the Repurchase Date and the person or persons in whose name
or names any certificate or certificates for shares of Common Stock shall be
issuable upon such repurchase shall be deemed to have become on the Repurchase
Date the holder or holders of record of the shares represented thereby;
PROVIDED, HOWEVER, that any surrender for repurchase on a date when the stock
transfer books of the Company shall be closed shall constitute the person or
persons in whose name or names the certificate or certificates for such shares
are to be issued as the record holder or holders thereof for all purposes at the
opening of business on the next succeeding day on which such stock transfer
books are open.

                  (h) No fractional shares of Common Stock or scrip representing
fractional shares shall be issued upon repurchase of Securities. If more than
one Security shall be repurchased from the same Holder and the Repurchase Price
shall be payable in shares of Common Stock, the number of full shares that shall
be issued upon repurchase shall be computed on the basis of the aggregate
principal amount of the Securities (or specified portions thereof to the extent
permitted hereby) so repurchased from such Holder. If any fractional share of
stock otherwise would be issuable upon repurchase of any Security or Securities,
the Company shall make an adjustment therefor by paying to the Holder thereof an
amount of cash calculated at the price per share at which the Common Stock is
valued for purposes of Section 11.01.

                  (i) The issue of stock certificates on repurchase of
Securities shall be made without charge to the Holder being repurchased for any
tax in respect of the issue thereof. The Company shall not, however, be required
to pay any tax that may be payable in respect of any transfer involved in the
issue and delivery of stock in any name other than that of the Holder of any
Security repurchased, and the Company shall not be required to issue or deliver
any such stock

                                     -54-

<PAGE>

certificate unless and until the person or persons requesting the issue
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

                  (j) Notwithstanding anything to the contrary in this Section
11.03, the Company shall not be required to give the Company Notice following
the occurrence of a Change in Control if:

                           (i) it shall notify the Trustee in writing no later
         than 20 days after the Change in Control that another Person shall make
         the offer and repurchase as hereafter set forth and of the identity of
         the appropriate officers of such Person to liaise with the Trustee with
         respect thereto; and

                           (ii) in the manner, at the time and otherwise in
         compliance with the requirements set forth herein regarding the
         Company's obligation to offer to repurchase the Outstanding Securities
         following the occurrence of a Change in Control, (A) another Person
         makes an offer to repurchase the Outstanding Securities, (B) such
         Person repurchases all Outstanding Securities validly tendered and not
         withdrawn, and (C) such Person makes all payments with respect thereto.

         Notwithstanding the foregoing, the Company shall remain at all times
the sole obligor with respect to all of its obligations hereunder (unless the
Trustee shall have entered into a supplemental indenture complying with Article
8 hereof providing for another Person to succeed to the Company hereunder and
assume the covenants of the Company hereunder), and any failure of the
performance of any such offer or repurchase obligation in the absence of such a
supplemental indenture shall be a failure by the Company as if the Company were
itself giving the Company Notice and repurchasing Outstanding Securities in
accordance herewith.

         SECTION 11.04. CERTAIN DEFINITIONS. For purposes of this Article 11:

                  (a) the terms "BENEFICIAL OWNER" and "BENEFICIAL OWNERSHIP"
shall be determined in accordance with Rules 13d-3 and 13d-5 promulgated by the
Commission pursuant to the Securities Exchange Act of 1934, as amended (the
"EXCHANGE ACT"), except that a Person shall be deemed to have "beneficial
ownership" of all securities that such Person has the right to acquire, whether
such right is exercisable immediately or only after the passage of time; and

                  (b) the term "PERSON" shall include any syndicate or group
that would be deemed to be a "Person" under Section 13(d)(3) or Section 14(d)(2)
of the Exchange Act.

         SECTION 11.05. CHANGE IN CONTROL. A "CHANGE IN CONTROL" shall be deemed
to have occurred at such time after the original issuance of the Securities as:

                  (a) any Person acquires the beneficial ownership, directly or
indirectly, through a purchase, merger or other acquisition transaction, of more
than 50% of the total voting power of the

                                     -55-

<PAGE>

total outstanding voting stock of the Company other than an acquisition by
the Company, any of its Subsidiaries or any of its employee benefit plans;

                  (b) the Company shall consolidate with, or merge with or into,
another Person or convey, transfer, lease or otherwise dispose of all or
substantially all of its assets to any Person, or any Person consolidates with
or merges with or into the Company, in any such event pursuant to a transaction
in which the Company's outstanding voting stock is converted into or exchanged
for cash, securities or other property, other than any such transactions where:

                           (i) the Company's voting stock is not converted or
exchanged at all (except to the extent necessary to reflect a change in the
Company's jurisdiction of incorporation) or is converted into or exchanged for
voting stock (other than Redeemable Capital Stock) of the surviving or
transferee corporation; and

                           (ii) immediately after such transaction, no Person
other than one or more Persons who were the beneficial owner, directly or
indirectly, of more than 50% of the total voting power of all of the Company's
voting stock immediately before such transaction, is the beneficial owner,
directly or indirectly, of more than 50% of the total outstanding voting stock
of the surviving or transferee corporation;

                  (c) during any consecutive two-year period, individuals who at
the beginning of such period constituted the Board of Directors (together with
any new directors whose election to such Board of Directors, or whose nomination
for election by the Company's stockholders, was approved by a vote of a majority
of the directors then still in office who were either directors at the beginning
of such period or whose election or nomination for election was previously so
approved) cease for any reason to constitute a majority of the Board of
Directors then in office;

                  (d) a special resolution is passed by the Company's
stockholders approving a plan of liquidation or dissolution of the Company
(other than in a transaction that complies with the provisions described in
Article 7), and no additional approvals of the Company's stockholders are
required under applicable law to cause such a liquidation or dissolution.

         "REDEEMABLE CAPITAL STOCK" means any class or series of capital stock
that, either by its terms, by the terms of any security into which it is
convertible or exchangeable or by contract or otherwise, is, or upon the
happening of an event or passage of time would be, required to be redeemed prior
to the Stated Maturity of the Securities or is redeemable at the option of the
holder thereof at any time prior to such Stated Maturity, or is convertible into
or exchangeable for debt securities at any time prior to such Stated Maturity;
PROVIDED, HOWEVER, that Redeemable Capital Stock shall not include any Common
Stock the holder of which has the right to put to the Company upon termination
of such holder's employment.

                                   ARTICLE 12
                                   CONVERSION

         SECTION 12.01. CONVERSION PRIVILEGE, CONVERSION RATE AND CONVERSION
PRICE. Subject to and upon compliance with the provisions of this Article 12, at
the option of the Holder thereof, any Security or any portion of the principal
amount thereof that is $1,000 or an integral multiple of $1,000 may be converted
at any time after original issuance thereof through the close of business on
March 1, 2007 into that number of fully paid and non-assessable shares of Common
Stock obtained by multiplying the Conversion Rate then in effect by each $1,000
principal amount of Securities surrendered for conversion. In case a Security or
portion thereof has previously been called for redemption at the election of the
Company, such conversion right in respect of the Security or portion so called
shall expire at the close of business, New York City time, on the last Business
Day prior to the Redemption Date, unless the Company defaults in making the
payment due upon redemption. A Security in respect of which a Holder has
delivered a Change in Control Purchase Notice (as defined in Article 11 hereof)
exercising the option of such Holder to require the Company to purchase such
Security may be converted only if such notice and the Security is withdrawn by a
written notice of withdrawal delivered by the Holder to the Trustee or any
Paying Agent prior to the close of business on the Repurchase Date, in
accordance with the terms of this Indenture.

         The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "CONVERSION PRICE") shall be initially $271.20 per
share of Common Stock, which is equal to a conversion rate of 3.6873 shares per
$1,000 principal amount of the Securities (the "CONVERSION RATE"). The
Conversion Rate shall be adjusted in certain instances as provided in Section
12.04 and, in every instance in which an adjustment is made to the Conversion
Rate, a corresponding adjustment shall be made to the Conversion Price. After
giving effect to the Announced Split (as such term is defined in Section
12.04(a)), the initial Conversion Price would be $135.60 per share of Common
Stock, which is equal to a conversion rate of 7.3746 shares per $1,000 principal
amount of the Securities.

         SECTION 12.02. EXERCISE OF CONVERSION PRIVILEGE. In order to exercise
the conversion privilege with respect to any Security in definitive form, the
Holder of any Security to be converted shall surrender such Security, duly
endorsed or assigned to the Company or in blank, at any office or agency
maintained by the Company pursuant to Section 9.02, accompanied by (a) written
notice to the Company in substantially the form of conversion notice attached to
the form of Security attached as Exhibit A hereto at such office or agency that
the Holder elects to convert such Security or, if less than the entire principal
amount thereof is to be converted, the portion thereof to be converted, (b) the
funds, if any, required by this Section 12.02, and (c) if shares or any portion
of such Security not to be converted are to be issued in the name of a Person
other than the Holder thereof, the name of the Person in which to issue such
shares and the transfer taxes, if any, required to be paid by the Holder
pursuant to Section 12.08.

         In order to exercise the conversion privilege with respect to any
interest in a global Security, the beneficial owner must complete, or cause to
be completed, the appropriate instruction form for conversion pursuant to the
depositary's book-entry conversion program, deliver, or cause to be

                                     -57-

<PAGE>

delivered, by book-entry delivery an interest in such global Security,
furnish appropriate endorsements and transfer documents if required by the
Company or the Trustee or other agent, and pay the funds if any required by
this Section 12.02 and any transfer taxes if required pursuant to Section
12.08.

         As promptly as practicable after satisfaction of all of the
requirements for conversion set forth above, but in any event no later than the
seventh business day following such date, the Company shall issue and shall
deliver to such Holder a certificate or certificates for the number of full
shares of Common Stock issuable upon the conversion of such Security or portion
thereof in accordance with the provisions of this Article and bearing the legend
set forth in Section 3.04(b) and a check or cash in respect of any fractional
interest in respect of a share of Common Stock arising upon such conversion, as
provided in Section 12.03. In case any Security of a denomination greater than
$1,000 shall be surrendered for partial conversion, and subject to Article 2,
the Company shall execute and the Trustee shall authenticate and deliver to the
holder of the Security so surrendered, without charge, a new Security or
Securities in authorized denominations in an aggregate principal amount equal to
the unconverted portion of the surrendered Security.

         Each conversion shall be deemed to have been effected as to any such
Security (or portion thereof) on the date on which all of the requirements set
forth above in this Section 12.02 have been satisfied as to such Security (or
portion thereof), and the Person in whose name any certificate or certificates
for shares of Common Stock shall be issuable upon such conversion shall be
deemed to have become on said date the holder of record of the shares
represented thereby; PROVIDED HOWEVER that any such surrender on any date when
the stock transfer books of the Company shall be closed shall constitute the
Person in whose name the certificates are to be issued as the record holder
thereof for all purposes on the next succeeding day on which such stock transfer
books are open, but such conversion shall be at the Conversion Rate in effect on
the date upon which such Security shall be surrendered.

         Any Security or portion thereof surrendered for conversion during the
period from the close of business on the record date for any interest payment
date to the opening of business on the Interest Payment Date, except notes to be
redeemed on a date within that period, shall be accompanied by payment, in
immediately available funds or other funds acceptable to the Company, of an
amount equal to the interest otherwise payable on such interest payment date on
the principal amount being converted; PROVIDED HOWEVER that no such payment need
be made to the extent any overdue interest shall exist at the time of conversion
with respect to any such Security or portion thereof. Except as provided above
in this Section 12.02, no payment or other adjustment shall be made for interest
accrued on any Security converted or for dividends on any shares issued upon the
conversion of such Security as provided in this Article.

         Upon the conversion of an interest in a global Security, the Trustee
(or other conversion agent appointed by the Company), shall make a notation on
such global Security as to the reduction in the principal amount represented
thereby. The Company shall notify the Trustee in writing of any conversions of
Securities effected through any conversion agent other than the Trustee.

                                     -58-

<PAGE>

         SECTION 12.03. FRACTIONS OF SHARES. No fractional shares of Common
Stock 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 that shall be issuable upon conversion thereof shall be computed
on the basis of the aggregate principal amount of the Securities (or specified
portions thereof) so surrendered. Instead of any fractional share of Common
Stock that would otherwise be issuable upon conversion of any Security (or
specified portions thereof), the Company shall pay a cash adjustment in respect
of such fraction in an amount equal to the same fraction of the Closing Price
per share of the Common Stock at the close of business on the Trading Day
immediately preceding such day.

         "TRADING DAY" shall mean each day on which the primary securities
exchange or quotation system that is used to determine the Closing Price is open
for trading or quotation.

         "CLOSING PRICE" of a single share of Common Stock on any Trading Day
shall mean the closing sale price per share for the Common Stock (or if no
closing sale price is reported, the average of the bid and ask prices) on such
Trading Day on the principal United States national securities exchange on which
the Common Stock is traded or, if the Common Stock is not listed on a United
States national stock exchange, as reported by the National Association of
Securities Dealers Automated Quotation System.

         SECTION 12.04. ADJUSTMENT OF CONVERSION RATE.

                  (a) In case the Company shall pay or make a dividend or other
distribution on its Common Stock exclusively in Common Stock (including the
Announced Split), the Conversion Rate in effect at the opening of business on
the earlier of the day next following such dividend or other distribution or the
date fixed for the determination of stockholders entitled to receive such
dividend or other distribution (except in the case of the Announced Split, which
shall be that Conversion Rate in effect at the opening of business on February
23, 2000) shall be adjusted so that a Holder upon conversion will be entitled to
receive that number of shares of Common Stock it would have been entitled to
after such dividend or other distribution if it had converted its Security
immediately prior to such dividend or other distribution. The term "Announced
Split" shall refer to the two-for-one stock split in the form of a stock
dividend announced on December 2, 1999 to be paid on February 22, 2000 to
stockholders of record on February 1, 2000.

                  (b) In case the Company shall pay or make a dividend or other
distribution on its Common Stock consisting exclusively of, or shall otherwise
issue to all holders of its Common Stock, rights, warrants or options entitling
the holders thereof, for a period not exceeding 45 days from the record date of
such issuance, to subscribe for or purchase shares of Common Stock at a price
per share less than the current market price per share (determined as provided
in Section 12.04(g)) of the Common Stock on the date fixed for the determination
of stockholders entitled to receive such rights, warrants or options, the
Conversion Rate in effect at the opening of business on the day following the
date fixed for such determination shall be increased by multiplying such
Conversion Rate by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination plus the number of shares of Common Stock so offered for
subscription or purchase and the denominator

                                     -59-

<PAGE>

shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination plus the number of shares
of Common Stock which the aggregate price of the total number of shares so
offered would purchase at the current market price per share (determined as
provided in Section 12.04(g)), such increase to become effective immediately
after the opening of business on the day following the date fixed for such
determination. 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 Rate 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
for the total number of shares of Common Stock offered.

                  (c) In case outstanding shares of Common Stock shall be
subdivided into a greater number of shares of Common Stock, the Conversion Rate
in effect at the opening of business on the day following the day upon which
such subdivision becomes effective shall be proportionately increased, and,
conversely, in case outstanding shares of Common Stock shall each be combined
into a smaller number of shares of Common Stock, the Conversion Rate in effect
at the opening of business on the day following the day upon which such
combination becomes effective shall be proportionately reduced, such increase or
reduction, as the case may be, to become effective immediately after the opening
of business on the day following the day upon which such subdivision or
combination becomes effective.

                  (d) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock evidences of its indebtedness,
shares of any class of capital stock, securities, cash or assets (excluding any
rights, warrants or options referred to in Section 12.04(b), any dividend or
distribution paid exclusively in cash and any dividend or distribution referred
to in Section 12.04(a)), the Conversion Rate shall be adjusted by multiplying
the Conversion Rate in effect immediately prior to the earlier of such
distribution or the determination of stockholders entitled to receive such
distribution by a fraction of which the numerator shall be the current market
price per share (determined as provided in Section 12.04(g)) and the denominator
shall be such current market price less the fair market value (as determined in
good faith by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution), on the date of such effectiveness, of the
portion of the evidences of indebtedness, shares of capital stock, securities,
cash and assets so distributed applicable to one share of Common Stock, such
adjustment to become effective immediately prior to the opening of business on
the day next following the later of (i) the date fixed for the payment of such
distribution and (ii) the date 20 days after the notice relating to such
distribution is given pursuant to Section 12.06 (such later date of (i) and (ii)
being referred to as the "REFERENCE DATE"). The provisions of this Section
12.04(d) shall not be applicable to an event covered by Section 12.04(j). For
purposes of this Section 12.04(d) and Sections 12.04(a) and 12.04(b), any
dividend or distribution for which an adjustment is being made pursuant to this
Section 12.04(d) that also includes shares of Common Stock or rights, warrants
or options to subscribe for or purchase shares of Common Stock shall be deemed
instead to be (A) a dividend or distribution of the evidences of indebtedness,
cash, property, shares of capital stock or securities other than such shares of
Common Stock or such rights, warrants or options (making any Conversion Rate
adjustment required by this Section 12.04(d)) immediately followed by (B) a
dividend or

                                     -60-

<PAGE>

distribution of such shares of Common Stock or such rights (making any
further Conversion Rate adjustment required by Sections 12.04(a) or
12.04(b)), except (1) the record date of such dividend or distribution as
defined in this Section 12.04(d) shall be substituted as "the date fixed for
the determination of stockholders entitled to receive such dividend or other
distributions", "the date fixed for the determination of stockholders
entitled to receive such rights, warrants or options" and "the date fixed for
such determination" within the meaning of Sections 12.04(a) and 12.04(b) and
(2) any shares of Common Stock included in such dividend or distribution
shall not be deemed "outstanding at the close of business on the date fixed
for such determination" within the meaning of this 12.04(a).

                  (e) In case the Company shall, by dividend or otherwise, make
a distribution to all holders of its Common Stock exclusively in cash in an
aggregate amount that, together with (i) the aggregate amount of any other
distributions to all holders of its Common Stock made exclusively in cash within
the 12 months preceding the date of payment of such distribution and in respect
of which no Conversion Rate adjustment pursuant to this Section 12.04(e) has
been made and (ii) the aggregate of any cash plus the fair market value (as
determined in good faith by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution), as of the expiration of the
tender or exchange offer referred to below, of consideration payable in respect
of any tender or exchange offer by the Company or a Subsidiary for all or any
portion of the Common Stock concluded within the 12 months preceding the date of
payment of such distribution and in respect of which no Conversion Rate
adjustment pursuant to this Section 12.04(e) has been made, exceeds 10% of the
product of the current market price per share (determined as provided in Section
12.04(g)) of the Common Stock as of the Trading Day immediately preceding the
record date fixed for stockholders entitled to receive such distribution times
the number of shares of Common Stock outstanding on such record date, the
Conversion Rate shall be increased so that the same shall equal the price
determined by multiplying the Conversion Rate in effect immediately prior to the
close of business on the date fixed for the determination of the stockholders of
record entitled to such distribution by a fraction of which the denominator
shall be the current market price per share (determined as provided in Section
12.04(g)) on such date less an amount equal to the quotient of (x) the excess of
such combined amount over such 10% and (y) the number of shares of Common Stock
outstanding on the record date and (iii) the numerator shall be equal to the
current market price on such date, such adjustment to become effective
immediately prior to the opening of business on the day following the record
date fixed for the payment of such distribution.

                  (f) In case a successful tender or exchange offer, other
than an odd lot offer, made by the Company or any Subsidiary for all or any
portion of the Common Stock shall involve an aggregate consideration having a
fair market value (as determined in good faith by the Board of Directors,
whose determination shall be conclusive and described in a Board Resolution)
as of the trading day next succeeding the last date (the "EXPIRATION TIME")
tenders or exchanges may be made pursuant to such tender or exchange offer
(as it may be amended) that, together with (i) the aggregate of the cash plus
the fair market value (as determined in good faith by the Board of Directors,
whose determination shall be conclusive and described in a Board Resolution),
as of the expiration of the other tender or exchange offer referred to below,
of consideration payable in respect of any other tender or exchange offer by
the Company or a Subsidiary for all or any portion

                                     -61-

<PAGE>

of the Common Stock concluded within the preceding 12 months and in respect
of which no Conversion Rate adjustment pursuant to this Section 12.04(f) has
been made and (ii) the aggregate amount of any distributions to all holders
of the Common Stock made exclusively in cash within the preceding 12 months
and in respect of which no Conversion Rate adjustment pursuant to Section
12.04(e) has been made, exceeds 10% of the product of the current market
price per share (determined as provided in Section 12.04(g)) of the Common
Stock outstanding (including any tendered shares) on the Expiration Time, the
Conversion Rate shall be adjusted by multiplying the Conversion Rate in
effect immediately prior to the Expiration Time by a fraction of which the
denominator shall be (i) the product of the current market price per share
(determined as provided in Section 12.04(g)) of the Common Stock on the
Trading Day next succeeding the Expiration Time times the number of shares of
Common Stock outstanding (including any tendered or exchanged shares) at the
Expiration Time minus (ii) the fair market value (determined as aforesaid) of
the aggregate consideration payable to stockholders based on the acceptance
(up to any maximum specified in the terms of the tender or exchange offer) of
all shares validly tendered or exchanged and not withdrawn as of the
Expiration Time (the shares deemed so accepted, up to any such maximum, being
referred to as the "PURCHASED SHARES") and the numerator shall be the product
of (i) such current market price per share (determined in accordance with
Section 12.04(g)) on the Trading Day next succeeding the Expiration Time
times (ii) such number of outstanding shares at the Expiration Time less the
number of Purchased Shares, such increase to become effective immediately
prior to the opening of business on the day following the Expiration Time.

                  (g) For the purpose of any computation under Sections
12.04(b), (d) and (e), the current market price per share of Common Stock on
any date in question shall be deemed to be the average of the daily Closing
Prices per share of Common Stock for the ten consecutive Trading Days
immediately prior to the date in question; PROVIDED, HOWEVER, that (i) if the
"ex" date (as hereinafter defined) for any event (other than the issuance or
distribution requiring such computation) that requires an adjustment to the
Conversion Rate pursuant to Section 12.04(a), (b), (c), (d), (e) or (f)
("OTHER EVENT") occurs on or after the 20th Trading Day prior to the date in
question and prior to the "ex" date for the issuance or distribution
requiring such computation (the "CURRENT EVENT"), the Closing Price for each
Trading Day prior to the "ex" date for such Other Event shall be adjusted by
multiplying such Closing Price by the reciprocal of the fraction by which the
Conversion Rate is so required to be adjusted as a result of such Other
Event, (ii) if the "ex" date for any Other Event occurs after the "ex" date
for the Current Event and on or prior to the date in question, the Closing
Price for each Trading Day on and after the "ex" date for such Other Event
shall be adjusted by multiplying such Closing Price by the fraction by which
the Conversion Rate is so required to be adjusted as a result of such Other
Event, (iii) if the "ex" date for any Other Event occurs on the "ex" date for
the Current Event, one of those events shall be deemed for purposes of
clauses (i) and (ii) of this proviso to have an "ex" date occurring prior to
the "ex" date for the Other Event, and (iv) if the "ex" date for the Current
Event is on or prior to the date in question, after taking into account any
adjustment required pursuant to clause (ii) of this proviso, the Closing
Price for each Trading Day on or after such "ex" date shall be adjusted by
adding thereto the amount of any cash and the fair market value on the date
in question (as determined in good faith by the Board of Directors in a
manner consistent with any determination of such value for purposes of
Section 12.04(d) or (e), whose determination shall be conclusive and
described in a Board Resolution) of the portion of the

                                     -62-

<PAGE>

rights, warrants, options, evidences of indebtedness, shares of capital
stock, securities, cash or property being distributed applicable to one share
of Common Stock. For the purpose of any computation under Section 12.04(f),
the current market price per share of Common Stock on any date in question
shall be deemed to be the average of the daily Closing Prices for the five
consecutive Trading Days selected by the Company commencing on or after the
latest (the "COMMENCEMENT DATE") of (i) the date 20 Trading Days before the
date in question, (ii) the date of commencement of the tender or exchange
offer requiring such computation and (iii) the date of the last amendment, if
any, of such tender or exchange offer involving a change in the maximum
number of shares for which tenders are sought or a change in the
consideration offered, and ending not later than the Trading Day next
succeeding the Expiration Time of such tender or exchange offer (or, if such
Expiration Time occurs before the close of trading on a Trading Day, not
later than the Trading Day during which the Expiration Time occurs);
PROVIDED, HOWEVER, that if the "ex" date for any Other Event (other than the
tender or exchange offer requiring such computation) occurs on or after the
Commencement Date and on or prior to the Trading Day next succeeding the
Expiration Time for the tender or exchange offer requiring such computation,
the Closing Price for each Trading Day prior to the "ex" date for such Other
Event shall be adjusted by multiplying such Closing Price by the reciprocal
of the same fraction by which the Conversion Rate is so required to be
adjusted as a result of such other event. For purposes of this paragraph, the
term "ex" date, (i) when used with respect to any issuance or distribution,
means the first date on which the Common Stock trades regular way on the
relevant exchange or in the relevant market from which the Closing Price was
obtained without the right to receive such issuance or distribution, (ii)
when used with respect to any subdivision or combination of shares of Common
Stock, means the first date on which the Common Stock trades regular way on
such exchange or in such market after the time at which such subdivision or
combination becomes effective, and (iii) when used with respect to any tender
or exchange offer means the first date on which the Common Stock trades
regular way on such exchange or in such market after the Expiration Time of
such tender or exchange offer.

                  (h) The Company may make such increases in the Conversion
Rate, in addition to those required by paragraphs (a), (b), (c), (d), (e), (f)
and (g) of this Section 12.04, as it considers to be advisable.

                  (i) No adjustment in the Conversion Rate shall be required
unless such adjustment would require an increase or decrease of at least 1% in
the Conversion Rate; PROVIDED, HOWEVER, that any adjustments, which by reason of
this Section 12.04(i) are not required to be made, shall be carried forward and
taken into account in any subsequent adjustment.

                  (j) No adjustment in the Conversion Rate is necessary if
Holders may participate in the transactions otherwise giving rise to an
adjustment on a basis and with notice that the Company's Board of Directors
determines to be fair and appropriate, or in other cases specified in this
Indenture.

                  (k) In the event that the Company distributes assets, debt
securities, rights, warrants or options (other than those referred to in Section
12.04(b)) pro rata to holders of Common Stock, and the fair market value of the
portion of assets, debt securities, rights, warrants or options

                                     -63-

<PAGE>

applicable to one share of Common Stock distributed to holders of Common
Stock exceeds the Average Sale Price (as defined below) per share of Common
Stock, or such Average Sale Price exceeds such fair market value by less than
$1.00, then so long as any such assets, debt securities, rights, options or
warrants have not expired or been redeemed by the Company, the Company shall
make proper provision so that the Holder of any Security upon conversion,
rather than being entitled to an adjustment in the Conversion Rate, will be
entitled to receive upon such conversion, in addition to the shares of Common
Stock otherwise issuable upon conversion, the kind and amount of assets, debt
securities, rights, warrants and options such Holder would have received had
such Holder converted its Security immediately prior to the date of
determination of the holders entitled to such distribution.

         "AVERAGE SALE PRICE" means the average of the Closing Prices of the
Common Stock for the shorter of (i) 30 consecutive Trading Days ending on the
last full Trading Day prior to the Time of Determination (as defined below)
with respect to the rights, options, warrants or distribution in respect of
which the Average Sale Price is being calculated, or (ii) the period (x)
commencing on the date next succeeding the first public announcement of (a)
the issuance of rights, options or warrants or (b) the distribution, in each
case, in respect of which the Average Sale Price is being calculated and (y)
proceeding through the last full Trading Day prior to the Time of
Determination with respect to the rights, options, warrants or distribution
in respect of which the Average Sale Price is being calculated, or (iii) the
period, if any, (x) commencing on the date next succeeding the Ex-Dividend
Time (as defined below) with respect to the next preceding (a) issuance of
rights, warrants or options or (b) distribution, in each case, for which an
adjustment is required by the provisions of Section 12.04(b) or Section
12.04(k) and (y) proceeding through the last full Trading Day prior to the
Time of Determination with respect to the rights, options, warrants, or
distribution in respect of which the Average Sale Price is being calculated.
If the Ex-Dividend Time (or in the case of a subdivision, combination or
reclassification, the effective date with respect thereto) with respect to a
dividend, subdivision, combination or reclassification to which Section
12.04(a), (b) or (c)applies occurs during the period applicable for
calculating "Average Sale Price" pursuant to the definition in the preceding
sentence, "Average Sale Price" shall be calculated for such period in a
manner determined in good faith by the Board of Directors to reflect the
impact of such dividend, subdivision, combination or reclassification on the
Closing Price of the Common Stock during such period.

         "TIME OF DETERMINATION" means the time and date of the earlier of (i)
the determination of stockholders entitled to receive rights, warrants or
options or a distribution, in each case, to which this Section 12.04 applies and
(ii) the time ("EX-DIVIDEND TIME") immediately prior to the commencement of
"ex-dividend" trading for such rights, options, warrants or distribution on the
New York Stock Exchange or such other national or regional exchange or market on
which the shares of Common Stock are listed or quoted.

         SECTION 12.05. NOTICE OF ADJUSTMENTS OF CONVERSION RATE. Whenever the
Conversion Rate and Conversion Price are adjusted as herein provided, the
Company shall compute the adjusted Conversion Rate and Conversion Price in
accordance with Section 12.04 and shall prepare a certificate signed by the
Chief Financial Officer of the Company setting forth the adjusted

                                     -64-

<PAGE>

Conversion Rate and Conversion Price and showing in reasonable detail the
facts upon which such adjustment is based, and such certificate shall
forthwith be filed (with a copy to the Trustee) at each office or agency
maintained for the purpose of conversion of Securities pursuant to Section
9.02; and the Company shall forthwith cause a notice setting forth the
adjusted Conversion Rate and Conversion Price to be mailed, first class
postage prepaid, to each Holder of Securities at its address appearing on the
Security Register. Unless and until the Trustee shall receive such notice,
the Trustee may assume without inquiry that the Conversion Rate and
Conversion Price have not been, and are not required to be, adjusted and that
the last Conversion Rate and Conversion Price of which it has written notice
remain in effect.

         SECTION 12.06. NOTICE OF CERTAIN CORPORATE ACTION. In case:

                  (a) the Company shall declare a dividend (or any other
distribution) on its Common Stock that would require a Conversion Rate
adjustment pursuant to Section 12.04(e); or

                  (b) the Company shall authorize the granting to all holders of
its Common Stock of rights, warrants or options to subscribe for or purchase any
shares of capital stock of any class or of any other rights (excluding rights
distributed pursuant to any stockholder rights plan); or

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

                  (e) the Company or any Subsidiary of the Company shall
commence a tender or exchange offer for all or a portion of the Company's
outstanding shares of Common Stock (or shall amend any such tender or exchange
offer);

         then the Company shall cause to be filed at each office or agency
maintained for the purpose of conversion of Securities pursuant to Section 9.02,
and shall cause to be mailed to all Holders at their last addresses as they
shall appear in the Security Register, at least 20 days (or 10 days in any case
specified in clause 12.06(a) or 12.06(b) above) prior to the applicable record,
effective or expiration 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 granting of 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, rights, warrants or options 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, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up,
or (z) the date on which such tender offer commenced, the date on which

                                     -65-

<PAGE>

such tender offer is scheduled to expire unless extended, the consideration
offered and the other material terms thereof (or the material terms of any
amendment thereto).

         SECTION 12.07. COMPANY'S OBLIGATION REGARDING COMMON STOCK. The Company
shall at all times reserve and keep available, free from preemptive rights, out
of its authorized but unissued Common Stock, solely for the purpose of effecting
the conversion of Securities, the whole number of shares of Common Stock then
issuable upon the conversion in full of all Outstanding Securities.

         Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Securities, the Company shall take all corporate
action that may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue shares of such Common Stock at such
adjusted Conversion Price.

         The Company covenants that if any shares of Common Stock to be provided
for the purpose of conversion of Securities hereunder require registration with
or approval of any governmental authority under any federal or state law before
such shares may be validly issued upon conversion, the Company shall in good
faith and as expeditiously as practicable endeavor to secure such registration
or approval, as the case may be.

         The Company further covenants that so long as the Common Stock shall be
listed or quoted on the New York Stock Exchange, the Nasdaq Stock Market
(National Market), or any other national securities exchange the Company shall,
if permitted by the rules of such exchange, list and keep listed so long as the
Common Stock shall be so listed on such market or exchange, all Common Stock
issuable upon conversion of the Securities.

         SECTION 12.08. TAXES ON CONVERSIONS. The Company shall pay any and all
taxes that may be payable in respect of the issue or delivery of shares of
Common Stock on conversion of Securities pursuant hereto. The Company shall not,
however, be required to pay any tax that may be payable in respect of any
transfer involved in the issue and delivery of shares of Common Stock in a name
other than that of the Holder of the Security or Securities to be converted, and
no such issue or delivery shall be made unless and until the Person requesting
such issue has paid to the Company the amount of any such tax, or has
established to the satisfaction of the Company that such tax has been paid.

         SECTION 12.09. COVENANT AS TO COMMON STOCK. The Company covenants that
all shares of Common Stock that may be issued upon conversion of Securities
shall upon issue be newly issued (and not treasury shares) and shall be duly
authorized, validly issued, fully paid and nonassessable and, except as provided
in Section 12.08, the Company shall pay all taxes, liens and charges with
respect to the issue thereof.

         SECTION 12.10. CANCELLATION OF CONVERTED SECURITIES. All Securities
delivered for conversion shall be delivered to the Trustee to be cancelled by or
at the direction of the Trustee, which shall dispose of the same as provided in
Section 3.08.

                                     -66-

<PAGE>

         SECTION 12.11. PROVISIONS IN CASE OF RECLASSIFICATION, CONSOLIDATION,
MERGER OR SALE OF ASSETS. In the event that the Company shall be a party to any
transaction (including any (i) recapitalization or reclassification of the
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 of the Common Stock), (ii) any consolidation of the Company with, or
merger of the Company into, any other person, any merger of another person into
the Company (other than a merger that does not result in a reclassification,
conversion, exchange or cancellation of outstanding shares of Common Stock of
the Company), (iii) any sale, lease, transfer conveyance or other disposition of
all or substantially all of the assets of the Company or (iv) any compulsory
share exchange) pursuant to which the Common Stock is converted into the right
to receive other securities, cash or other property, then lawful provision shall
be made as part of the terms of such transaction whereby the Holder of each
Security then Outstanding shall have the right thereafter to convert such
Security only into (subject to funds being legally available for such purpose
under applicable law at the time of such conversion) the kind and amount of
securities, cash and other property receivable upon such transaction by a holder
of the number of shares of Common Stock into which such Security might have been
converted immediately prior to such transaction. The Company or the Person
formed by such consolidation or resulting from such merger or that acquired such
assets or that acquired the Company's shares of Common Stock, as the case may
be, shall execute and deliver to the Trustee a supplemental indenture
establishing such rights. Such supplemental indenture shall provide for
adjustments that, for events subsequent to the effective date of such
supplemental indenture, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Article. The above provisions of this
Section 12.11 shall similarly apply to successive transactions of the foregoing
type.

         SECTION 12.12. COMPANY'S OBLIGATION. All calculations, adjustments,
conversions and other determinations under this Article 12 shall be the sole
responsibility and obligation of the Company. The Trustee (a) shall have no
obligation to review, challenge or contest any such calculation, adjustment,
conversion or other determination and (b) shall not be liable for any default or
error by the Company under this Article 12.

                                   ARTICLE 13
                                  SUBORDINATION

         SECTION 13.01. SECURITIES SUBORDINATE TO SENIOR INDEBTEDNESS. The
Company covenants and agrees, and each Holder of Securities, by such Holder's
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article 13, the indebtedness
represented by the Securities and the payment of the principal of (and premium,
if any), and interest (including Liquidated Damages, if any) on and all other
amounts payable under the Securities are hereby expressly made subordinate and
subject in right of payment to the prior payment in full in cash or other
payment satisfactory to Holders of Senior Indebtedness of all existing and
future Senior Indebtedness.

                                     -67-

<PAGE>

         SECTION 13.02. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC. In the
event of any payment by, or distribution of the assets of, the Company in
connection with (a) any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relative to the Company or its assets, (b) any
liquidation, dissolution or other winding-up of the Company, whether voluntary
or involuntary and whether or not involving insolvency or bankruptcy, or (c) any
assignment for the benefit of creditors or any other marshaling of assets and
liabilities of the Company, then and in any such event the holders of Senior
Indebtedness shall be entitled to receive payment in full of all amounts due in
respect of all Senior Indebtedness, or provision shall be made for such payment
in cash or cash equivalents or otherwise in a manner satisfactory to the holders
of Senior Indebtedness, before the Holders of the Securities are entitled to
receive any payment on account of principal of (or premium, if any), or interest
(including Liquidated Damages, if any) on or any other amount payable under the
Securities, ratably according to the aggregate amounts remaining unpaid on
account of such Senior Indebtedness held by them, for application to the payment
thereof, any payment or distribution of any kind or character, whether in cash,
property or securities, that may be payable or deliverable in respect of the
Securities in any such case, proceeding, dissolution, liquidation or other
winding-up or event, after giving effect to any concurrent payment or
distribution, or provision therefore, to the holders of such Senior
Indebtedness.

         In the event that, notwithstanding the foregoing provisions of this
Section 13.02, the Trustee or the Holder of Securities shall have received any
payment or distribution of assets of the Company prohibited by the foregoing
paragraph of any kind or character, whether in cash, property or securities,
before all Senior Indebtedness is paid in full or payment thereof provided for,
and if, at or prior to the time of such payment or distribution, written notice
that such payment or distribution is prohibited by the foregoing paragraph shall
have been actually given to a Responsible Officer of the Trustee or, as the case
may be, such Holder, then and in such event such payment or distribution shall
be paid over or delivered forthwith to holders of such Senior Indebtedness
remaining unpaid or their representatives 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.

         For purposes of this Article 13 only, the words "CASH, PROPERTY OR
SECURITIES" shall not be deemed to include shares of capital stock of the
Company as reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment that in
either case are subordinated in right of payment to all Senior Indebtedness that
may at the time be outstanding to substantially the same extent as, or to a
greater extent than, the Securities are so subordinated as provided in this
Article 13. The consolidation of the Company with, or the merger of the Company
into, another Person or the liquidation or dissolution of the Company following
the conveyance, transfer or other disposition of its properties and assets
substantially as an entirety to another Person upon the terms and conditions set
forth in Article 7 shall not be deemed a dissolution, winding-up, liquidation,
reorganization, assignment for the benefit of creditors or marshaling of assets
and liabilities of the Company for the purposes of this Section 13.02 if the
Person formed by such consolidation or into which the Company is merged or that
acquires by sales, lease, conveyance, transfer or other disposition such
properties and assets substantially as an entirety, as

                                     -68-

<PAGE>

the case may be, shall, as a part of such consolidation, merger, sales,
lease, conveyance, transfer or other disposition, comply with the conditions
set forth in Article 7.

         SECTION 13.03. NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT. (a) In
the event and during the continuation of any default in the payment of principal
of (or premium, if any) or interest on any Senior Indebtedness beyond any
applicable grace period with respect thereto (unless and until such payment
default shall have been cured or waived in writing by the holders of such Senior
Indebtedness), or (b) any default (other than a payment default) with respect to
Senior Indebtedness occurs and is continuing that permits the acceleration of
the maturity thereof and judicial proceedings shall be pending with respect to
any such default or the Company receives written notice of such default (a
"SENIOR INDEBTEDNESS DEFAULT NOTICE"), then no payment shall be made by the
Company on account of principal of (or premium, if any) or interest (including
Liquidated Damages, if any) on the Securities or on account of all other amounts
payable under the Securities. Notwithstanding the foregoing, payments with
respect to the Securities may resume, and the Company may acquire Securities for
cash or property, when (x) the default with respect to the Senior Indebtedness
is cured or waived or ceases to exist or (y) in the case of a default described
in clause (b) of this Section 13.03, 179 or more days pass after the Senior
Indebtedness Default Notice is received by the Company. If the Company receives
a Senior Indebtedness Default Notice, then a similar notice received within one
year thereafter relating to the default that was the basis of such Senior
Indebtedness Default Notice, on the same issue of Senior Indebtedness, shall not
be effective to prevent the payment or acquisition of the Securities as
described in the first sentence of this Section 13.03(a). In addition, no
payment may be made on the Securities if any Securities are declared due and
payable prior to their Stated Maturity by reason of the occurrence of an Event
of Default resulting from the acceleration of the maturity of any Senior
Indebtedness until the earlier of (i) 120 days after the date of such
acceleration of the maturity of the Securities or (ii) the payment in full of
all Senior Indebtedness in cash or other consideration satisfactory to the
holders of such Senior Indebtedness, but only if such payment is then otherwise
permitted under the terms of this Indenture.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of Securities prohibited by the
foregoing provisions of this Section 13.03 before all Senior Indebtedness is
paid in full, or effective provisions made for its payment, and if, at or prior
to the time of such payment, written notice that such payment is prohibited by
the foregoing paragraph shall have been actually given to a Responsible Officer
of the Trustee or, as the case may be, such Holder, then and in such event (but
subject to the provisions of Section 13.09) such payment shall be paid over and
delivered forthwith to the holders of such Senior Indebtedness remaining unpaid
or their representatives 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.

         The provisions of this Section 13.03 shall not apply to any payment
with respect to which Section 13.02 would be applicable.

         SECTION 13.04. PAYMENT PERMITTED IF NO DEFAULT. Nothing contained in
this Article 13 or elsewhere herein or in any of the Securities shall prevent
(a) the Company, at any time except during the pendency of any case, proceeding,
dissolution, liquidation or other winding-up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Company referred
to in Section 13.02, except under the conditions described in Section 13.03,
from making payments at any time of principal of (and premium, if any), or
interest on, or any other amount payable under the Securities, or (b) the
application by the Trustee of any money deposited with it hereunder to the
payment of or on account of the principal of (and premium, if any), or interest
on, or any other amount payable under the Securities, or the retention of such
payment by the Holders, if, by the close of business on the date that was two
Business Days prior to such application by the Trustee, the Trustee had not
received written notice that such payment would be prohibited by the provisions
of this Article 13.

         SECTION 13.05. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.
Upon payment in full of all Senior Indebtedness, the Holders of the Securities
shall be subrogated (equally and ratably with the holders of all Indebtedness of
the Company that by its express terms is subordinated to Indebtedness of the
Company to substantially the same extent as the Securities are subordinated to
Senior Indebtedness) to the rights of the holders of such Senior Indebtedness to
receive payments and distributions of cash, property and securities applicable
to the Senior Indebtedness to the extent that payments and distributions
otherwise payable to Holders of Securities have been applied to the payment of
Senior Indebtedness as provided by this Article 13. For purposes of such
subrogation, no payments or distributions to the holders of the Senior
Indebtedness of any cash, property or securities to which the Holders of the
Securities or the Trustee would be entitled, except for the provisions of this
Article 13, and no payments over pursuant to the provisions of this Article 13
to the holders of Senior Indebtedness by Holders of the Securities or the
Trustee, shall, as among the Company, its creditors other than holders of Senior
Indebtedness and the Holders of the Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.

         SECTION 13.06. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS. The
provisions of this Article 13 are and are intended solely for the purpose of
defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article 13 or elsewhere herein or in the Securities is intended to or
shall:

                  (a) impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the obligation
of the Company, which is absolute and unconditional (and which, subject to the
rights under this Article 13 of the holders of Senior Indebtedness, is intended
to rank equally with all other general obligations of the Company), to pay to
the Holders of the Securities the principal of (and premium, if any), and
interest (including Liquidated Damages, if any) on, and any other amount payable
under the Securities, as and when the same shall become due and payable in
accordance with their terms;

                                     -70-

<PAGE>

                  (b) affect the relative rights against the Company of the
Holders of the Securities and other creditors of the Company, other than
Holders' rights in relation to the holders of Senior Indebtedness; or

                  (c) prevent the Trustee or the Holder of any Securities from
exercising all remedies available upon a Default or Event of Default under this
Indenture, subject to the rights, if any, under this Article 13 of the holders
of Senior Indebtedness to receive cash, property and securities otherwise
payable or deliverable to the Trustee or such Holder.

         SECTION 13.07. TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder of
Securities by its acceptance thereof authorizes and directs the Trustee on its
behalf to take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article 13 and appoints the Trustee its
attorney-in-fact for any and all such purposes, including the immediate filing
of a claim for the unpaid balance of such Holder's Securities in any insolvency
or bankruptcy proceeding, or any receivership, liquidation, reorganization or
similar case or proceeding, in the form required in such proceeding, and the
taking of such actions as may be required to cause such claim to be approved. If
the Trustee does not file a proper claim in the form required in such proceeding
on or prior to thirty days before the expiration of the time to file such claim
or claims, then the holders of Senior Indebtedness or their representatives are
hereby authorized to file such claim for and on behalf of the Holders.

         SECTION 13.08. NO WAIVER OF SUBORDINATION PROVISIONS. No right of any
present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof any such holder may have or be otherwise charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article 13
or the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following:

                  (a) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, Senior Indebtedness, or otherwise amend
or supplement in any manner Senior Indebtedness or any instrument evidencing the
same or any agreement under which Senior Indebtedness is outstanding;

                  (b) sell, exchange, release or otherwise deal with any
property pledged, mortgaged or otherwise securing Senior Indebtedness;

                  (c) release any Person liable in any manner for the collection
of Senior Indebtedness; and

                                     -71-

<PAGE>

                  (d) exercise or refrain from exercising any rights against the
Company and any other Person.

         SECTION 13.09. NOTICE TO TRUSTEE. The Company shall give prompt written
notice to the Trustee if, to the Company's knowledge, any payment to or by the
Trustee in respect of the Securities is prohibited by this Article 13.
Notwithstanding the provisions of this Article 13 or any other provision of this
Indenture, the Trustee shall not be charged with knowledge that any payment to
or by the Trustee in respect of the Securities is prohibited by this Article 13,
unless and until a Responsible Officer of the Trustee shall have received
written notice thereof from the Company or a holder of Senior Indebtedness or
from any trustee therefor or other representative thereof; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 1.05, shall be entitled in all respects to assume that no facts exist
that would prohibit any payment in respect of the Securities; PROVIDED, HOWEVER,
that if a Responsible Officer of the Trustee shall not have received at the
Corporate Trust Office of the Trustee the notice provided for in this Section
13.09 by the close of business on the date that is two Business Days prior to
the date upon which by the terms hereof any money may become payable for any
purpose (including the payment of the principal of (and premium, if any) or
interest (including Liquidated Damages, if any) on any Security), then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such money and to apply the same to the purpose
for which such money was received and shall not be affected by any notice to the
contrary which may be received by it after the close of business on the date
that is two Business Days prior to such date.

         Subject to the provisions of Article 5, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
itself to be a holder of Senior Indebtedness (or a representative thereof) to
establish that such notice has been given by a holder of Senior Indebtedness (or
a representative thereof). 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 13, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 13, 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 13.10. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT. Upon any payment or distribution of assets of the Company referred to in
this Article 13, the Trustee, subject to the provisions of Article 5, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the

                                     -72-

<PAGE>

amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article 13.

         SECTION 13.11. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall in good faith mistakenly pay over or distribute to Holders of Securities
or to the Company or to any other Person cash, property or securities to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
13 or otherwise.

         SECTION 13.12. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS;
PRESERVATION OF TRUSTEE'S RIGHTS. The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article 13 with respect to any
Senior Indebtedness which may at any time be held by it, to the same extent as
any other holder of Senior Indebtedness, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder.

         Nothing in this Article 13 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 5.07.

         SECTION 13.13. 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 13
shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article 13 in
addition to or in place of the Trustee; PROVIDED, HOWEVER, that Section 13.13
shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent.

         SECTION 13.14. CERTAIN CONVERSIONS DEEMED PAYMENT. For the purposes of
this Article 13 only, (1) the issuance and delivery of junior securities upon
conversion of Securities in accordance with Article 12 or in respect to the
Repurchase Price in accordance with Article 11 shall not be deemed to constitute
a payment or distribution on account of the principal of or premium or interest
(including Liquidated Damages, if any) on, or other amount payable with respect
to, Securities or on account of the redemption, purchase or other acquisition of
Securities, and (2) the payment, issuance or delivery of cash, property or
securities (other than junior securities) upon conversion of a Security shall be
deemed to constitute payment on account of the principal of, premium or interest
on, or other amount payable with respect to, such Security. For the purposes of
this Section 13.14, the term "JUNIOR SECURITIES" means (a) shares of any stock
of any class of the Company and (b) securities of the Company that are
subordinated in right of payment to the prior payment in full of all Senior
Indebtedness that 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 13. Nothing contained
in this Article 13 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 12.

CUSIP 89674KAA1

         TRIQUINT SEMICONDUCTOR, INC., a corporation duly organized and existing
under the laws of the State of Delaware (herein called the "COMPANY," which term
includes any successor entity under the Indenture hereinafter referred to), for
value received, hereby promises to pay to Cede & Co., or registered assigns, the
principal sum of THREE HUNDRED MILLION DOLLARS ($300,000,000) at the office or
agency of the Company referred to below, on March 1, 2007 in such coin or
currency of the United States of America as at the time of payment shall be
legal tender for the payment of public and private debts, and to pay interest on
said principal sum semiannually on March 1 and September 1 of each year,
commencing September 1, 2000 (each an "INTEREST PAYMENT DATE"), at said office
or agency, in like coin or currency, at the rate of 4% per annum, until the
principal hereof is paid or made available for payment. The interest so payable,
and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, which shall be the February 15 or
August 15 (whether or not a Business Day), as the case may be, next preceding
such Interest Payment Date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities not less
than 10 days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture.

         Payment of the principal of, premium, if any (including the Make-Whole
Payment, if any), and interest (including Liquidated Damages, if any) on this
Security shall be made at the office or agency of the Company maintained for
such purpose, which initially shall be the Corporate Trust Office of the Trustee
or such other office or agency of the Company as may be designated by it in the
Borough of Manhattan, The City of New York, in such lawful money of the United
States of America as at the time of payment is legal tender for payment of
public and private debts, PROVIDED that the Company may make such payment either
by (i) mailing a check in the amount of such

<PAGE>

payment, payable to or upon the written order of the Person entitled thereto
pursuant to Section 3.07 of the Indenture (as defined herein) or (ii) transfer
to an account maintained by the payee located inside the United States.

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

         IN WITNESS WHEREOF, the Company has caused this instrument to be duly

                         [FORM OF REVERSE OF SECURITY]

                         TRIQUINT SEMICONDUCTOR, INC.

                   4% CONVERTIBLE SUBORDINATED NOTE DUE 2007

         This Security is one of a duly authorized issue of securities of the
Company designated as its 4% Convertible Subordinated Notes due 2007 (herein
called the "SECURITIES"), limited in aggregate principal amount to $300,000,000
(up to $345,000,000 if the option set forth in Section 2(b) of the Purchase
Agreement dated February 17, 2000 among the Company and the Initial Purchasers
named therein is exercised in full), which may be issued under an Indenture,
dated as of February 24, 2000 (the "INDENTURE"), between the Company and State
Street Bank and Trust Company of California, N.A., as Trustee for the Holders of
Securities issued under said Indenture (herein called the "TRUSTEE", which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee, the holders of Senior Indebtedness and the Holders of
the Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered.

         [The Holder of this Security [if this security is a global security,
then insert -- (including any Person that has a beneficial interest in this
Security)] and the Common Stock of the Company issuable upon conversion hereof
is entitled to the benefits of a Registration Rights Agreement, dated as of
February 24, 2000 executed by the Company (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 the Registrable Securities to pay
additional interest on this Security ("Liquidated Damages") in accordance with
the terms of the Registration Rights Agreement. Whenever in this Security there
is a reference, in any context, to 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 payable as
described in this paragraph to the extent that, in such context, Liquidated
Damages are, were or would be payable in respect of such Security and express
mention of the payment of Liquidated Damages (if applicable) in any provisions
of this Security shall not be construed as excluding Liquidated Damages in those
provisions of this Security where such express mention is not made.]

         Subject to and upon compliance with the provisions of the Indenture,
the Holder of this Security is entitled, at its option, at any time on or before
maturity of the Securities, or in case this Security or a portion hereof is
called for redemption, then in respect of this Security or such portion hereof
until and including, but (unless the Company defaults in making the payment due
upon redemption or repurchase) not after, the close of business on the Business
Day immediately preceding the Redemption Date or Repurchase Date, as the case
may be, to convert this Security (or any portion of the principal amount hereof
which is U.S. $1,000 or an integral multiple thereof), at the principal amount
hereof, or of such portion, into fully paid and nonassessable shares of Common

                                      -3-

<PAGE>

Stock of the Company at a Conversion Price of $135.60 per share of Common Stock,
which is equal to a Conversion Rate of 7.3746 shares of Common Stock per $1,000
principal amount of the Securities (or at the current adjusted Conversion Price
and Conversion Rate if an adjustment has been made as provided in Article 12 of
the Indenture) by surrender of this Security, duly endorsed or assigned to the
Company or in blank, to the Company at its office or agency maintained for such
purpose, accompanied by the conversion notice hereon executed by the Holder
hereof evidencing such Holder's election to convert this Security, or if less
than the entire principal amount hereof is to be converted, the portion hereof
to be converted, and, in case such surrender shall be made during the period
from the close of business on any Regular Record Date to the opening of business
on the corresponding Interest Payment Date (unless this Security or the portion
hereof being converted has been called for redemption on a Redemption Date
within such period between and including such Regular Record Date and such
Interest Payment Date), also accompanied by payment in funds acceptable to the
Company of an amount equal to the interest payable on such Interest Payment Date
on the principal amount of this Security then being converted. Subject to the
aforesaid requirement for payment of interest and, in the case of a conversion
after the close of business on any Regular Record Date and on or before the
corresponding Interest Payment Date, to the right of the Holder of this Security
(or any Predecessor Security) of record at such Regular Record Date to receive
an installment of interest (even if the Security has been called for redemption
on a Redemption Date within such period), no payment or adjustment is to be made
on conversion for interest accrued hereon or for dividends on the Common Stock
issued on conversion. No fractions of shares or scrip representing fractions of
shares will be issued on conversion, but instead of any fractional interest the
Company shall pay a cash adjustment as provided in Article 12 of the Indenture.
The Conversion Rate and Conversion Price are subject to adjustment as provided
in Article 12 of the Indenture. In addition, the Indenture provides that in case
of certain reclassifications, consolidations, mergers, sales or transfers of
assets or other transactions pursuant to which the Common Stock is converted
into the right to receive other securities, cash or other property, the
conversion privilege shall be modified so that this Security, if then
outstanding, will be convertible thereafter, during the period this Security
shall be convertible as specified above, only into the kind and amount of
securities, cash and other property receivable upon the transaction by a holder
of the number of shares of Common Stock into which this Security might have been

"PROVISIONAL REDEMPTION"), at a Redemption Price equal to $1,000 per $1,000
principal amount of the Securities plus accrued and unpaid interest, if any, to
but excluding the date of redemption (the "PROVISIONAL REDEMPTION DATE") if (i)

(as defined in Article 12 of the Indenture and as such may be adjusted from time

consecutive Trading Days ending on the Trading Day prior to the date of mailing
of the provisional notice of redemption pursuant to Section 10.04 (the "NOTICE
DATE"), and (ii) a registration statement covering resales of the Securities and
Common Stock issuable upon the conversion thereof is effective and available for

         Upon any such Provisional Redemption, the Company shall make an

Common Stock between the Notice Date and the Provisional Redemption Date, in an

accordance with the terms of the Indenture) are subject to redemption at the
option of the Company upon not less than 30 days' or more than 60 days' notice
by mail (unless a shorter notice is deemed satisfactory by the Trustee), as a

such redemption, with accrued interest to (but not including) the Redemption
Date (subject to the right of holders of record on the Regular Record Date to
receive interest on the related Interest Payment Date). Any redemption of
Securities must be in integral multiples of $1,000.

         If fewer than all of the Securities are to be redeemed, the Trustee
shall select the Securities to be redeemed in principal amounts at maturity of
$1,000 or integral multiples thereof by lot, pro rata or by another method the
Trustee considers fair and appropriate. If a portion of a Holder's Securities is
selected for partial redemption and that holder converts a portion of those
Securities prior to the redemption, the converted portion shall be deemed,
solely for purposes of determining the aggregate principal amount of the
Securities to be redeemed by the Company, to be of the portion selected for
redemption.

         In certain circumstances involving a Change in Control, each Holder
shall have the right to require the Company to repurchase all or part of its
Securities at a repurchase price equal to 100% of the principal amount thereof,
together with accrued and unpaid interest through the Repurchase Date (subject
to the right of holders of record on the Regular Record Date to receive interest
on the related Interest Payment Date). At the option of the Company, the
Repurchase Price may be paid in cash or, subject to the conditions provided in
the Indenture, by delivery of shares of Common Stock.

         The Securities do not have the benefit of any sinking fund.

                                      -5-

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

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

         If an Event of Default shall occur and be continuing, the principal of
all the Securities may be declared due and payable in the manner and with the
effect provided in Article 4 of the Indenture.

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

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of, premium, if any
(including the Make-Whole Payment, if any), and interest (including Liquidated
Damages, if any) on this Security at the times, place and rate, and in the coin
or currency, herein prescribed or to convert this Security as provided in the
Indenture.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
Corporate Trust Office duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

         The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.

                                      -6-

<PAGE>

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

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary.

         Interest (including Liquidated Damages, if any) on this Security shall
be computed on the basis of a 360-day year of twelve 30-day months. In the event
that any date on which interest is payable on the Securities is not a Business
Day, then payment of interest payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay).

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

         THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF
LAWS PRINCIPLES.

the Company of any material changes to the Requisite Information contained in
the Notice and Questionnaire provided to the Company by such Holder.

         If any such Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require, in the event that such reference to such Holder by
name or otherwise is not required by the Securities Act or any similar Federal
statute then in force, the deletion of the reference to such Holder in such
Registration Statement at the time subsequent to the time that such reference
ceases to be required and the Company otherwise intends to amend our supplement
the Shelf Registration Statement.

         (d) MATERIAL EVENTS; SUSPENSION OF SALES. Notwithstanding the
provisions contained in this Section 2, in the event that, in the judgment of
the Company's Board of Directors, it is advisable to suspend use of the
Prospectus due to pending corporate developments, public filings with the SEC
or similar events, the Company shall promptly deliver a written certificate
to each registered Holder, the Trustee, the Transfer Agent and the managing
underwriters, if any, to the effect that the use of the Prospectus is to be
suspended until the Company shall deliver a written notice that the use of
the Prospectus may be resumed. Thereafter, the use of the Prospectus shall be
suspended, and the Company shall not be required to maintain the effectiveness
of, or amend or update the Shelf Registration Statement, or amend or
supplement the Prospectus; PROVIDED, HOWEVER, that the Company shall only be
permitted to suspend the use of the Prospectus for a period not to exceed 90
days in any consecutive 365 days. The Company will use its best efforts to
ensure that the use of the Prospectus may be resumed as soon as, in the
judgment of the Company's Board of Directors,

                                       6

<PAGE>

disclosure of the material relating to such pending development, filing or
event would not have a material adverse effect on the Company.

         (e) ADDITIONAL AGREEMENTS OF HOLDERS. Each Holder agrees not to
dispose of Transfer Restricted Securities pursuant to the Shelf Registration
Statement without complying with the prospectus delivery requirements under
the Act and the provisions of paragraph (d) above regarding use of the
Prospectus. Each Holder further agrees that it will comply fully with
applicable federal and state securities laws in connection with the
distribution of any Transfer Restricted Securities pursuant to the Shelf
Registration Statement. Each Holder further acknowledges having been advised
by the Company that applicable federal securities laws prohibit Holders from
trading in securities of the Company at any time while in possession of
material non-public information about the Company.

         SECTION 3.  LIQUIDATED DAMAGES.

         (a) The Company and the Initial Purchasers agree that the Holders
will suffer damages if the Company fails to fulfill its obligations pursuant
to Section 2 hereof and that it would not be possible to ascertain the extent
of such damages. Accordingly, the Company hereby agrees to pay liquidated
damages ("LIQUIDATED DAMAGES") to each Holder under the circumstances and to
the extent set forth below:

                      (i)   if the Shelf Registration Statement has not been
              filed with the SEC on or prior to the Filing Date; or

                      (ii)  if each Shelf Registration Statement is not declared
              effective by the SEC on or prior to the applicable Effectiveness
              Target Date; or

                      (iii) any Shelf Registration Statement ceases to be
              effective or usable at any time during the Effectiveness Period
              (without being succeeded on the same day immediately by a
              post-effective amendment or supplement to such Registration
              Statement that cures such failure and that is itself, in the case
              of post-effective amendment, immediately declared effective) for a
              period of time which shall exceed 90 days in the aggregate in any
              period of 365 consecutive days; (any of the foregoing, a
              "REGISTRATION DEFAULT").

         In the event of a Registration Default, the Company will pay Liquidated
Damages to each holder of Transfer Restricted Securities, during the first
90-day period immediately following the occurrence of such Registration Default
in an amount equal to $0.05 per week per $1,000 principal amount of Notes and
for any Common Stock constituting Transfer Restricted Securities, at such rate
adjusted to an equivalent per share basis in accordance with the conversion
price of the Notes after conversion. The rate of accrual of the Liquidated
Damages will

                                       7

<PAGE>

increase by $0.05 per week per $1,000 principal amount of Notes or Common
Stock constituting Transfer Restricted Securities (adjusted to an equivalent
per share basis in accordance with the conversion price for Common Stock
constituting Transfer Restricted Securities) for each subsequent 90-day
period until the applicable Registration Statement is filed, the applicable
Registration Statement is declared effective and becomes available for
effecting sales of securities, or the Shelf Registration Statement again
becomes effective and becomes available for effecting sales of securities, as
the case may be, up to a maximum amount of Liquidated Damages of $0.25 per
week per $1,000 principal amount of Notes adjusted to an equivalent per share
basis in accordance with the conversion price. Following the cure of a
Registration Default, Liquidated Damages will cease to accrue with respect to
such Registration Default (without in any way limiting the effect of any
subsequent Registration Default). All accrued Liquidated Damages shall be
paid to the holders of (i) Notes constituting Transfer Restricted Securities,
pursuant to the terms of the Indenture with respect to the payment of
interest and (ii) shares of Common Stock, in the manner as interest payments
on the Notes on semiannual payment dates that correspond to interest payment
dates for the Notes. The parties hereto agree and acknowledge that the
payment of Liquidated Damages to holders of Common Stock upon a Registration
Default pursuant to this Agreement shall not be a dividend on such shares of
Common Stock.

         (b) The Company shall notify the Transfer Agent or the Trustee, as
the case may be, within five Business Days after each and every date on which
a Registration Default occurs. Liquidated Damages, as calculated by the
Company, shall be paid by the Company to the Record Holders of Common Stock
on each Damages Payment Date by wire transfer of immediately available funds
to the accounts specified by them or by mailing checks to their registered
addresses as they appear in the register of the Company for the Common Stock,
if no such accounts have been specified in the Notice and Questionnaire on or
before the Damages Payment Date; and Liquidated Damages shall be paid by the
Company to the Record Holders of the Notes on each semi-annual interest
payment date together with interest to be paid on the Notes pursuant to the
terms of the Indenture, by wire transfer of immediately available funds to
the accounts specified by them or by mailing checks to their registered
addresses as they appear in the Notes Register (as defined in the Indenture)
if no such accounts have been specified in the Notice and Questionnaire on or
before the Damages Payment Date; PROVIDED, HOWEVER, that any Liquidated
Damages accrued with respect to any Notes or portion thereof called for
redemption on a redemption date, repurchased on a repurchase date, or
converted into shares of Common Stock on a conversion date prior to the
Damages Payment Date shall, in any such event, be paid instead to the Holder
who submitted such Notes or portion thereof for redemption, repurchase or
conversion on the applicable redemption date, repurchase date or conversion
date, as the case may be, on such date.

         SECTION 4. REGISTRATION PROCEDURES. In connection with the Company's
registration obligations hereunder, the Company shall effect such
registrations on the appropriate form selected by the Company to permit the
resale of Transfer Restricted Securities in accordance with the intended
method or methods of disposition thereof, and pursuant thereto the Company
shall as expeditiously as reasonably possible:

         (a) No fewer than five Business Days prior to the initial filing of
a Registration Statement or Prospectus and no fewer than two Business Days
prior to the filing of any amendment or supplement thereto (excluding, unless
requested, any document that would be incorporated or deemed to be
incorporated therein by reference and then only to the Holder who so
requested), furnish to the Holders whose Transfer Restricted Securities are
required to be included in such Registration Statement or Prospectus pursuant
to Section 2(c) hereof and the managing underwriters, if any, copies of all
such documents proposed to be filed (excluding, unless requested, those
incorporated or deemed to be incorporated by reference and then only to the
Holder who so requested) and cause the officers and directors of the Company,
counsel to the Company and independent certified public accountants to the
Company to respond to such inquiries as shall be necessary in connection with
such Registration Statement, in the opinion of counsel to the underwriters,
if any, to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file any such Registration Statement or
related Prospectus or any amendments or supplements thereto (excluding any
document that would be incorporated or deemed incorporated by reference) to
which the Holders of a majority in interest of the Transfer Restricted
Securities or the managing underwriters, if any, shall reasonably object on a
timely basis. The Company shall prepare and file with the SEC such
amendments, including post-effective amendments, to each Registration
Statement as may be necessary to keep such Registration Statement
continuously effective for the applicable time period set forth in Section
2(a) hereof; subject to Section 2(d) hereof, cause the related Prospectus to
be supplemented by any required Prospectus supplement, and as so supplemented
to be filed pursuant to Rule 424 under the Securities Act and the Exchange
Act with respect to the disposition of all securities covered by such
Registration Statement during such period in accordance with the intended
method or methods of disposition by the Holder set forth in such Registration
Statement as so amended or in such Prospectus as so supplemented (including,
without limitation, the filing of any Prospectus supplement pursuant to Rule
424 in order to add or change any selling security holder information
(including any such supplements or amendments pursuant to Section 2(c)
hereof, PROVIDED such Holder to which such change applies complies with the
Requisite Information requirements of Section 2(c) hereof)).

         (b) Notify the Holders and the managing underwriters, if any,
promptly (and in the case of an event specified by clause (i) of this
paragraph in

                                       9
<PAGE>

no event fewer than two Business Days prior to such filing), and (if
requested by any such person), confirm such notice in writing, (i) when a
Prospectus or any Prospectus supplement or post-effective amendment is
proposed to be filed, and, with respect to a Registration Statement or any
post-effective amendment, when the same has become effective, (ii) of any
request of the SEC or any other Federal or state governmental authority for
amendments or supplements to such Registration Statement or related
Prospectus or for additional information related thereto, (iii) of the
issuance by the SEC, any state securities commission, any other governmental
agency or any court of any stop order, order or injunction suspending or
enjoining the use or the effectiveness of the Registration Statement or the
initiation of any proceedings for that purpose, (iv) if at any time any of
the representations and warranties of the Company contained in any agreement
(including any underwriting agreement) contemplated by Section 4(m) hereof
are not true and correct in all material respects, (v) of the receipt by the
Company of any notification with respect to the suspension of the
qualification or exemption from qualification of any of the Transfer
Restricted Securities for sale in any jurisdiction, or the initiation or
threatening of any proceeding for such purpose, and (vi) of the existence of
any fact and the happening of any event that makes any statement made in such
Registration Statement or related Prospectus untrue in any material respect,
or that requires the making of any changes in such Registration Statement or
Prospectus so that in the case of the Registration Statement, 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 not misleading and that, in the case of the Prospectus, such
Prospectus 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 light of the circumstances under which they were
made, not misleading.

         (c) Use all reasonable efforts to avoid the issuance of, or, if
issued, to obtain the withdrawal of any stop order or order enjoining or
suspending the use or effectiveness of a Registration Statement or the
lifting of any suspension of the qualification (or exemption from
qualification) of any of the Transfer Restricted Securities for sale in any
jurisdiction, at the earliest practicable moment.

         (d) If requested by the managing underwriters, if any, or the
Holders of a majority in interest of the Transfer Restricted Securities being
sold in connection with such offering, promptly include in a Prospectus
supplement or post-effective amendment such information as the managing
underwriters, if any, and such Holders agree should, in their reasonable
judgment, be included therein, and 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
included in such Prospectus supplement or post-effective amendment; PROVIDED,
HOWEVER, that the Company shall not be required

                                       10
<PAGE>

to take any action pursuant to this Section 4(e) that, in the opinion of
counsel for the Company, would violate applicable law;

         (e) Furnish to each Holder who so requests and each managing
underwriter, if any, without charge, at least one conformed copy of each
Registration Statement and each amendment thereto, including financial
statements (but excluding schedules, all documents incorporated or deemed to
be incorporated therein by reference and all exhibits, unless requested in
writing by such Holder or any managing underwriter);

         (f) Deliver to each Holder and the underwriters, if any, without
charge, as many copies of the Prospectus or Prospectuses (including each form
of Prospectus) and each amendment or supplement thereto to as such persons
may reasonably request; and, unless the Company shall have given notice to
such Holder pursuant to Section 2(d), the Company hereby consents to the use
of such Prospectus and each amendment or supplement thereto by each of the
selling Holders of Transfer Restricted Securities and the underwriters, if
any, in connection with the offering and sale of the Transfer Restricted
Securities covered by such Prospectus and any amendment or supplement
thereto; PROVIDED, HOWEVER, that no Holder shall be entitled to use the
Prospectus unless and until such Holder shall have furnished to the Company
any and all Requisite Information pursuant to Section 2(c) hereof;

         (g) Use all reasonable efforts to register or qualify, or cooperate
with the Holders of Transfer Restricted Securities to be sold or tendered
for, the underwriters, if any, and their respective counsel in connection
with the registration or qualification (or exemption from such registration
or qualification) of, such Transfer Restricted Securities for offer and sale
under the securities or Blue Sky laws of such jurisdictions within the United
States as any Holder or underwriter reasonably requests in writing, 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 necessary legally to enable the
disposition in such jurisdictions of the Transfer Restricted Securities
covered by the applicable Registration Statement; PROVIDED, HOWEVER, that the
Company shall not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified, take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject or subject the Company to any tax in any such
jurisdiction where it is not then so subject;

         (h) In connection with any sale or transfer of Transfer Restricted
Securities that will result in such securities no longer being Transfer
Restricted Securities, cooperate with the Holders and the managing
underwriters, if any, to facilitate the timely preparation and delivery of
certificates representing Transfer Restricted Securities to be sold, which
certificates shall not bear any restrictive

                                       11
<PAGE>

legends, shall bear a CUSIP number different from the CUSIP number for the
Transfer Restricted Securities and shall be in a form eligible for deposit
with The Depository Trust Company and enable such Transfer Restricted
Securities to be in such denominations and registered in such names as the
managing underwriters, if any, or Holders may reasonably request at least two
Business Days prior to any sale of Transfer Restricted Securities;

         (i) Use all reasonable efforts to cause the offering of the Transfer
Restricted Securities covered by the Registration Statement to be registered
with or approved by such other governmental agencies or authorities within
the United States, except as may be required as a consequence of the nature
of a 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 as may be reasonably necessary to enable the
seller or sellers thereof or the underwriters, if any, to consummate the
disposition of such Transfer Restricted Securities PROVIDED, HOWEVER, that
the Company shall not be required to register the Transfer Restricted
Securities in any jurisdiction that would require the Company to qualify to
do business in any jurisdiction where it is not then so qualified, subject it
to general service of process in any such jurisdiction where it is not then
so subject or subject the Company to any tax in any such jurisdiction where
it is not then so subject or to;

         (j) Upon the occurrence of any event contemplated by Section
4(c)(vi) hereof, as promptly as reasonably practicable (subject to any
suspension of sales pursuant to Section 2(d) hereof), prepare a supplement or
amendment, including, if appropriate, a post-effective amendment, to each
Registration Statement or a supplement to the related Prospectus or any
document incorporated or deemed to be incorporated therein by reference, and
file any other required document so that, as thereafter delivered, 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;

         (k) Prior to the effective date of the first Registration Statement
relating to the Transfer Restricted Securities, to provide a CUSIP number for
the Transfer Restricted Securities to be sold pursuant to the Registration
Statement;

         (l) Make available for inspection by a representative of the Holders
of Transfer Restricted Securities being sold, and any attorney, consultant or
accountant retained by such selling Holders or underwriter, at the offices
where normally kept, during reasonable business hours, all financial and
other records, pertinent corporate documents and properties of the Company
and its subsidiaries as they may reasonably request, and cause the officers,
directors, agents and employees of the Company and its subsidiaries to supply
all information in each case reasonably requested by any such representative,
underwriter, attorney,

                                       12
<PAGE>

consultant or accountant in connection with such Registration Statement;
PROVIDED, HOWEVER, that such persons shall first agree in writing with the
Company that any information that is reasonably and in good faith designated
by the Company in writing as confidential at the time of delivery or
inspection (as the case may be) of such information shall be kept
confidential by such persons, unless (i) in the reasonable opinion of the
Company or its counsel, disclosure of such information is required by court
or administrative order or is necessary to respond to inquiries of regulatory
authorities, (ii) in the reasonable opinion of the Company or its counsel,
disclosure of such information is required by law (including any disclosure
requirements pursuant to Federal securities laws in connection with the
filing of any Registration Statement or the use of any Prospectus), (iii)
such information becomes generally available to the public other than as a
result of a disclosure or failure to safeguard by any such person or (iv)
such information becomes available to any such person from a source other

         (m) Use all reasonable efforts to cause the Indenture to be
qualified under the TIA not later than the effective date of the first
Registration Statement relating to the Transfer Restricted Securities; and in
connection therewith, cooperate with the Trustee and the Holders of Notes or
Common Stock constituting Transfer Restricted Securities to effect such
changes to the Indenture, if any, as may be required for such Indenture to be
so qualified in accordance with the terms of the TIA; and execute, and use
its best efforts to cause the Trustee to execute, all customary documents as
may be required to effect such changes, and all other forms and documents
(including Form T-1) required to be filed with the SEC to enable the
Indenture to be so qualified under the TIA in a timely manner.

         (n) Comply with applicable rules and regulations of the SEC and make
generally available to its security holders earning statements satisfying the
provisions of Section 11(a) of the Securities Act or Rule 158 (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) commencing at the end of any fiscal quarter
in which Transfer Restricted Securities are sold to underwriters in a firm
commitment or best efforts underwritten offering and if not sold to
underwriters in such an offering, commencing on the first day of the first
fiscal quarter after the effective date of a Registration Statement, which
statement shall cover said period, consistent with the requirements of Rule
158; and

         SECTION 5. REGISTRATION EXPENSES.

         All fees and expenses incident to the performance of or compliance
with this Agreement by the Company shall be borne by it whether or not any
Registration Statement is filed or becomes effective and whether or not any
securities are offered or sold pursuant to any Registration Statement. The
fees and expenses referred to in the foregoing sentence shall include,
without limitation, (i) all registration and filings fees (including, without
limitation, fees and expenses with respect to filings required to be made
with the National Association of Securities Dealers, Inc. and in compliance
with securities or blue sky laws), (ii) printing expenses (including, without
limitation, of printing Prospectuses if the printing of Prospectuses is
required by the managing underwriters, if any, or by the Holders of a
majority in interest of the Transfer Restricted Securities included), (iii)
messenger, telephone and delivery expenses, (iv) reasonable fees and
disbursements of counsel for the Company (plus any local counsel deemed
appropriate by the Holders of a majority in interest of the Transfer
Restricted Securities) in accordance with the provisions of this Section 5
hereof, (v) fees and disbursements of all independent certified public
accountants referred to in Section 4(m)(iii) (including, without limitation,

officers and employees performing legal or accounting duties), the expense of
an annual audit and the fees and expenses incurred in connection with the
listing of the securities to be registered on any securities exchange or the
Nasdaq SmallCap Market or the Nasdaq National Market. Notwithstanding
anything in this Agreement to the contrary, each Holder shall pay all
underwriting discounts and brokerage commissions with respect to any Transfer
Restricted Securities sold by it.

         SECTION 6. INDEMNIFICATION.

         (a) The Company agrees to indemnify and hold harmless each of (i)
the Initial Purchasers, (ii) each Holder, (iii) each person, if any, who
controls (within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act) any of the foregoing (any of the persons referred to
in this clause (iii) being hereinafter referred to as a "CONTROLLING
PERSON"), and (iv) the respective officers, directors, partners, employees,
representatives and agents of the Initial Purchasers, the Holders (including
predecessor Holders), or any controlling person (any person referred to in
clause (i), (ii), (iii) or (iv) may hereinafter be referred to as an
"INDEMNIFIED PERSON"), from and against any and all losses, claims, damages,
liabilities, expenses and judgments caused by any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement
or Prospectus or in any amendment or supplement thereto or in any preliminary
Prospectus, or caused by any omission or alleged omission

                                       14
<PAGE>

to state therein a material fact required to be stated therein or necessary
to make the statements therein (in the case of any Prospectus or supplement
thereto, in the light of the circumstances under which they were made) not
misleading, except insofar as such losses, claims, damages, liabilities,
expenses or judgments are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information relating to any
Indemnified Person furnished to the Company by or on behalf of such
Indemnified Person expressly for use therein (which shall include, without
limitation, the Requisite Information in the Notice and Questionnaire
provided to the Company by such Indemnified Person); PROVIDED, HOWEVER, that
the foregoing indemnity with respect to any preliminary Prospectus shall not
inure to the benefit of any Indemnified Person from whom the person asserting
such losses, claims, damages, liabilities, expenses and judgments purchased
securities if such untrue statement or omission or alleged untrue statement
or omission made in such preliminary Prospectus is eliminated or remedied in
the Prospectus and a copy of the Prospectus shall not have been furnished to
such person in a timely manner due to the wrongful action or wrongful
inaction of such Indemnified Person, whether as a result of negligence or
otherwise.

         (b) In case any action shall be brought against any Indemnified
Person, based upon any Registration Statement or any such Prospectus or any
amendment or supplement thereto and with respect to which indemnity may be
sought against the Company, such Indemnified Person shall promptly notify the
Company in writing and the Company shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to such
Indemnified Person and payment of all fees and expenses. Any Indemnified
Person shall have the right to employ separate counsel in any such action and
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Person, unless the employment of
such counsel shall have been specifically authorized in writing by the
Company, the Company shall have failed to assume the defense and employ
counsel or such Indemnified Person or Persons shall have been advised by
counsel that there may be a conflict between the positions of the
indemnifying party or parties and of the indemnified party or parties in
conducting the defense of such action or proceeding or that there may be
legal defenses available to such Indemnified Person or Persons different from
or in addition to those available to the indemnifying party or parties (in
which case the Company shall not have the right to assume the defense of such
action on behalf of such Indemnified Person, it being understood, however,
that the Company shall not, in connection with any one such action or
separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys
(in addition to any local counsel) for all such Indemnified Persons, which
firm shall be designated in writing by such Indemnified Persons, and that all
such fees and expenses shall be reimbursed as they are incurred). The Company
shall not be liable for any settlement of any

                                       15
<PAGE>

such action effected without its written consent but if settled with the
written consent of the Company, the Company agrees to indemnify and hold
harmless any Indemnified Person from and against any loss or liability by
reason of such settlement. No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is
or could have been a party and indemnity could have been sought hereunder by
such indemnified party, unless such settlement includes an unconditional
release of such indemnified party from all liability on claims that are the
subject matter of such proceeding.

         (c) In connection with any Registration Statement pursuant to which
any Holder (or predecessor Holder) sold or offered for resale Transfer
Restricted Securities, such Holder agrees, severally and not jointly, to
indemnify and hold harmless the Company, its directors, officers, employees,
representatives and agents and any person controlling the Company within the
meaning of 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
Indemnified Person but only with reference to information relating to such
Indemnified Person furnished by or on behalf of such Indemnified Person
expressly for use in such Registration Statement (which shall include,
without limitation, the Requisite Information in the Notice and Questionnaire
provided to the Company by such Indemnified Person). In case any action shall
be brought against the Company, any of its directors, officers, employees,
representatives and agents, or any person controlling the Company based on
such Registration Statement and in respect of which indemnity may be sought
against any Indemnified Person, the Indemnified Person shall have the rights
and duties given to the Company (except that if the Company shall have
assumed the defense thereof, such Indemnified Person shall not be required to
do so, but may employ separate counsel therein and participate in defense
thereof but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person), and the Company, its directors, officers,
employees, representatives and agents, and any person controlling the Company
shall have the rights and duties given to the Indemnified Person by Section
6(b) hereof.

         (d) If the indemnification provided for in this Section 6 is
applicable by its terms but unavailable to an indemnified party in respect of
any losses, claims, damages, liabilities, expenses or judgments referred to
therein, then each indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities,
expenses and judgments (i) in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and each
Indemnified Person on the other hand pursuant to the Purchase Agreement or
from the offering for resale of the Transfer Restricted Securities 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 Company and each such Indemnified Person in connection
with the statements or omissions which resulted in such losses, claims,
damages, liabilities, expenses or judgments, as well as any other relevant
equitable considerations. The relative fault of the Company and each such
Indemnified Person shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Company or such Indemnified Person and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         The Company, the Holders and the Initial Purchasers agree that it
would not be just and equitable if contribution pursuant to this Section 6(d)
were determined by PRO RATA allocation (even if the Indemnified Person were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to in
the immediately preceding paragraph. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, liabilities,
expenses or judgments referred to in the immediately preceding paragraph
shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 6, no Indemnified Person shall
be required to contribute any amount in excess of the amount by which the
total net profit received by it in connection with the sale of the Transfer
Restricted Securities pursuant to this Agreement exceeds the amount of any
damages which such Indemnified Person has otherwise been required to pay 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 Indemnified Persons' obligations to contribute
pursuant to this Section 6(d) are several in proportion to the respective
amount of Transfer Restricted Securities included in and sold pursuant to any
such Registration Statement by each Indemnified Person and not joint.

         SECTION 7. UNDERWRITTEN REGISTRATION.

         If any of the Transfer Restricted Securities covered by any Shelf
Registration Statement are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be investment bankers of recognized national
standing selected by the Holders of a majority in interest of such Transfer
Restricted Securities included in such offering, subject to the consent of
the Company (which will not be unreasonably withheld or delayed).

                                       17

         No person may participate in any underwritten registration hereunder
unless such person agrees to sell such person's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements, lock-up agreements and other documents reasonably
required under the terms of such underwriting arrangements.

         SECTION 8. MISCELLANEOUS.

         (a) REMEDIES. In the event of a breach by the Company or by a Holder
of any of their respective obligations under this Agreement, each Holder or
the Company, in addition to being entitled to exercise all rights granted by
law, including, without limitation, recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agree that, in the event of any action for
specific performance in respect of such breach, they shall waive the defense
that a remedy at law would be adequate. This Section 8(a) shall not apply to
any breach for which Liquidated Damages have been specifically provided
hereunder.

         (b) NO INCONSISTENT AGREEMENTS. The Company shall not enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. The Company is not currently a party to any agreement
granting any registration rights with respect to any of its securities to any
person which conflicts with the Company's obligations hereunder. Without
limiting the generality of the foregoing, without the written consent of the
Holders of a majority in interest of the Transfer Restricted Securities, the
Company shall not grant to any person the right to request it to register any
of its securities under the Securities Act unless the rights so granted are
subject in all respect to the prior rights of the Holders set forth herein,
and are not otherwise in conflict or inconsistent with the provisions of this
Agreement.

         (c) NO ADVERSE ACTION AFFECTING THE TRANSFER RESTRICTED SECURITIES.
The Company will not take any action with respect to the Transfer Restricted
Securities which would adversely affect the ability of any of the Holders to
include such Transfer Restricted Securities in a registration undertaken
pursuant to this Agreement.

         (d) NO PIGGYBACK ON REGISTRATIONS. After the date hereof, the
Company shall not grant to any of its security holders (other than the
Holders in such capacity) the right to include any of its securities in any
Shelf Registration Statement.

                                       18

         (e) AMENDMENTS AND WAIVERS. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions
hereof, may not be given, without the written consent of the Holders of a
majority in interest of the Transfer Restricted Securities; PROVIDED,
HOWEVER, that, for the purposes of this Agreement, Transfer Restricted
Securities that are owned, directly or indirectly, by either the Company or
an Affiliate of the Company are not deemed outstanding. 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 whose
Transfer Restricted Securities are being sold pursuant to an underwritten
offering and that does not directly or indirectly affect the rights of other
Holders may be given by Holders of a majority in interest of the Transfer
Restricted Securities being sold by such Holders pursuant to such an
underwritten offering; PROVIDED, HOWEVER, that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance
with the provisions of the immediately preceding sentence.

         (g) SUCCESSORS AND ASSIGNS. This Agreement shall inure to the
benefit of and be binding upon the successors and permitted assigns of each

the Transfer Restricted Securities, other than by operation of law pursuant

remain in full force and effect and shall in no way be affected, impaired or
invalidated, and the parties hereto shall use their best efforts to find and
employ an alternative means to achieve the same or substantially the same

It is hereby stipulated and declared to be the intention of the parties that
