deliver said Notes to or upon the written order of the Company, signed by its

regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Notes may be
listed, or to conform to usage.

as shall be specified therein and shall provide that it shall represent the
aggregate amount of outstanding Notes from time to time endorsed thereon and
that the aggregate amount of outstanding Notes represented thereby may from time
to time be increased or reduced to reflect transfers or exchanges permitted
hereby. Any endorsement of a Note in global form to reflect the amount of any
increase or decrease in the amount of outstanding Notes represented thereby
shall be made by the Trustee or the Custodian, at the direction of the Trustee,
in such manner and upon instructions given by the holder of such Notes in
accordance with this Indenture. Payment of principal of and interest and
premium, if any, on any Note in global form shall be made to the holder of such

         The terms and provisions contained in the form of Note attached as
Exhibit A hereto shall constitute, and are hereby expressly made, a part of this
Indenture and, to the extent applicable, the Company and the Trustee, by their
execution and delivery of this Indenture, expressly agree to such terms and
provisions and to be bound thereby.

         SECTION 2.3 DATE AND DENOMINATION OF NOTES; PAYMENTS OF INTEREST. The
Notes shall be issuable in registered form without coupons in denominations of
$1,000 principal amount and integral multiples thereof. Every Note shall be

Exhibit A hereto. Interest on the Notes shall be computed on the basis of a
360-day year comprised of twelve (12) 30-day months.

         The person in whose name any Note (or its Predecessor Note) is
registered on the Note register at the close of business on any record date with
respect to any interest payment date shall be entitled to receive the interest
payable on such interest payment date, except (i) that the interest payable upon
repurchase (unless the date of repurchase is an interest payment date) will be
payable only to the person to whom principal is payable pursuant to such
repurchase and (ii) as set forth in the next succeeding sentence. In the case of
any Note (or portion thereof) which is converted into Common Stock of the
Company during the period from (but excluding) a record date to (but excluding)
the next succeeding interest payment date either (i) if such Note (or portion
thereof) is to be repurchased in connection with a Fundamental Change on a
Repurchase Date (as defined in Section 3.1) which occurs during such period, the
Company shall not be required to pay interest on such interest payment date in
respect of any such Note (or portion thereof) except to the extent required to
be paid upon repurchase of such Note or portion thereof pursuant to Section 3.1
hereof or (ii) if otherwise, any Note (or portion thereof) submitted for
conversion during such period shall be accompanied by funds equal to the
interest payable on such succeeding interest payment date on the principal
amount so converted. Interest shall be payable at the office of the Company
maintained by the Company for such purposes in the Borough of Manhattan, The
City of New York, which shall initially be an office or agency of the Trustee
and may, as the Company shall specify to the paying

                                      -10-

<PAGE>

agent in writing by each record date, be paid either (i) by check mailed to the
address of the person entitled thereto as it appears in the Note register
(provided that the holder of Notes with an aggregate principal amount in excess
of $10,000,000 shall, at the written election of such holder, be paid by wire
transfer in immediately available funds) or (ii) by transfer to an account
maintained by such person located in the United States; provided, however, that
payments to the Depositary will be made by wire transfer of immediately
available funds to the account of the Depositary or its nominee. The term
"record date" with respect to any interest payment date shall mean the May 1 or
November 1 immediately preceding said May 15 or November 15, respectively.

         Any interest on any Note which is payable, but is not punctually paid
or duly provided for, on any said May 15 or November 15 (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Noteholder on
the relevant record date by virtue of his having been such Noteholder; and such
Defaulted Interest shall be paid by the Company, at its election in each case,
as provided in clause (1) or (2) below;

                           (i)      The Company may elect to make payment of any
Defaulted Interest to the persons in whose names the Notes (or their respective
Predecessor Notes) 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 to be paid on each Note and the date of the payment (which
shall be not less than twenty-five (25) days after the receipt by the Trustee of
such notice, unless the Trustee shall consent to an earlier date), and at the
same time the Company shall deposit with the Trustee an amount of money equal to
the aggregate amount to be paid in respect of such Defaulted Interest or shall
make arrangements satisfactory to the Trustee for such deposit prior to the date
of the proposed payment, such money when deposited to be held in trust for the
benefit of the persons entitled to such Defaulted Interest as in this clause
provided. Thereupon the Trustee shall fix a special record date for the payment
of such Defaulted Interest which shall be not more than fifteen (15) days and
not less than ten (10) days prior to the date of the proposed payment, and not
less than ten (10) days after the receipt by the Trustee of the notice of the
proposed payment, the Trustee shall promptly notify the Company of such special
record date and, in the name and at the expense of the Company, shall cause
notice of the proposed payment of such Defaulted Interest and the special record
date therefor to be mailed, first-class postage prepaid, to each Noteholder at
his address as it appears in the Note register, not less than ten (10) days
prior to such special record date. Notice of the proposed payment of such
Defaulted Interest and the special record date therefor having been so mailed,
such Defaulted Interest shall be paid to the persons in whose names the Notes
(or their respective Predecessor Notes) were registered at the close of business
on such special record date and shall no longer be payable pursuant to the
following clause (2) of this Section 2.3.

                           (ii)     The Company may make payment of any
Defaulted Interest in any other lawful manner not inconsistent with the
requirements of any securities exchange or automated quotation system on which
the Notes may be listed or designated for issuance, and upon such notice as may
be required by such exchange or automated quotation system, if, after notice
given by the

                                      -11-

<PAGE>

Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

         SECTION 2.4 EXECUTION OF NOTES. The Notes shall be signed in the name
and on behalf of the Company by the manual or facsimile signature of its Chief
Executive Officer, President, any Executive or Senior Vice President or any Vice
President (whether or not designated by a number or numbers or word or words
added before or after the title "Vice President") or Treasurer and attested by
the manual or facsimile signature of its Secretary or any of its Assistant
Secretaries or Treasurer or any of its Assistant Treasurers (which may be
printed, engraved or otherwise reproduced thereon, by facsimile or otherwise).
Only such Notes as shall bear thereon a certificate of authentication
substantially in the form set forth on the form of Note attached as Exhibit A
hereto, manually executed by the Trustee (or an authenticating agent appointed
by the Trustee as provided by Section 16.11), shall be entitled to the benefits
of this Indenture or be valid or obligatory for any purpose. Such certificate by
the Trustee (or such an authenticating agent) upon any Note executed by the
Company shall be conclusive evidence that the Note so authenticated has been
duly authenticated and delivered hereunder and that the holder is entitled to
the benefits of this Indenture.

         In case any officer of the Company who shall have signed any of the
Notes shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such
Notes nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Notes had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution of this Indenture any such
person was not such an officer.

         SECTION 2.5 EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES:
RESTRICTIONS ON TRANSFER; DEPOSITARY.

                  (a) The Company shall cause to be kept at the Corporate Trust
Office a register (the register maintained in such office and in any other
office or agency of the Company designated pursuant to Section 5.2 being herein
sometimes collectively referred to as the "Note register") in which, subject to
such reasonable regulations as it may prescribe, the Company shall provide for
the registration of Notes and of transfers of Notes. The Note register shall be
in written form or in any form capable of being converted into written form
within a reasonably prompt period of time. The Trustee is hereby appointed "Note
registrar" for the purpose of registering Notes and transfers of Notes as herein
provided. The Company may appoint one or more co-registrars in accordance with
Section 5.2.

         Upon surrender for registration of transfer of any Note to the Note
registrar or any co-registrar, and satisfaction of the requirements for such
transfer set forth in this Section 2.5, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Notes of any authorized denominations and of a
like aggregate principal amount and bearing such restrictive legends as may be
required by this Indenture.

                                      -12-

<PAGE>

         Notes may be exchanged for other Notes of any authorized denominations
and of a like aggregate principal amount, upon surrender of the Notes to be
exchanged at any such office or agency maintained by the Company pursuant to
Section 5.2. Whenever any Notes are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Notes which
the Noteholder making the exchange is entitled to receive bearing registration
numbers not contemporaneously outstanding.

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

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

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

         Neither the Company nor the Trustee nor any Note registrar shall be
required to exchange or register a transfer of (a) any Notes or portion thereof
surrendered for conversion pursuant to Article XV or (b) any Notes or portions
thereof tendered for repurchase (and not withdrawn) pursuant to Section 3.1.

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

                  (c) So long as the Notes are eligible for book-entry
settlement, or unless otherwise required by law, upon any transfer of a
definitive Note to a QIB in accordance with Rule 144A, and upon receipt of the
definitive Note or Notes being so transferred, together with a certification,

                                      -13-

<PAGE>

substantially in the form on the reverse of the Note, from the transferor that
the transfer is being made in compliance with Rule 144A (or other evidence
satisfactory to the Trustee), the Trustee shall make an endorsement on the
Global Note to reflect an increase in the aggregate Principal Amount of the
Notes represented by such Global Note, the Trustee shall cancel such definitive
Note or Notes in accordance with the standing instructions and procedures of the
Depositary, the aggregate Principal Amount of Notes represented by such Global
Note to be increased accordingly; provided that no definitive Note, or portion
thereof, in respect of which the Company or an Affiliate of the Company held any
beneficial interest shall be included in such Global Note until such definitive
Note is freely tradable in accordance with Rule 144(k) under the Securities Act;
provided further that the Trustee shall issue Notes in definitive form upon any
transfer of a beneficial interest in the Global Note to the Company or any
Affiliate of the Company.

         Upon any sale or transfer of a Note to an Institutional Accredited
Investor (other than pursuant to a registration statement that has been declared
effective under the Securities Act), such Institutional Accredited Investor
shall, prior to such sale or transfer, furnish to the Company and/or the Trustee
a signed letter containing representations and agreements relating to
restrictions on transfer substantially in the form set forth in Exhibit B to
this Indenture, together with an opinion of counsel acceptable to the Company if
such transfer is in respect of an aggregate principal amount of Notes less than
$100,000. Upon any transfer of a beneficial interest in the Global Note to an
Institutional Accredited Investor, the Trustee shall make an endorsement on the
Global Note to reflect a decrease in the aggregate Principal Amount of the Notes
represented by such Note in global form, and the Company shall execute a
definitive Note or Notes in exchange therefore, and the Trustee, upon receipt of
such definitive Note or Notes and the written order of the Company, shall
authenticate and deliver such, definitive Note or Notes.

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

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

                                      -14-

<PAGE>

and 2.5(e), the term "transfer" encompasses any sale, pledge, transfer or other
disposition whatsoever of any Restricted Security.

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

         THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED
STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED
STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, UNITED STATES PERSONS EXCEPT AS
SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1)
REPRESENTS THAT IT IS (A) A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE
144A UNDER THE SECURITIES ACT), (B) AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS
DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT)
("INSTITUTIONAL ACCREDITED INVESTOR"), OR (C) A NON-U.S. PERSON; (2) AGREES THAT
IT WILL NOT, PRIOR TO EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF
THE NOTE EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY
SUCCESSOR PROVISION), RESELL OR OTHERWISE TRANSFER THIS NOTE OR THE COMMON STOCK
ISSUABLE UPON CONVERSION OF THIS NOTE EXCEPT (A) TO LSI LOGIC CORPORATION OR ANY
SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A QUALIFIED INSTITUTIONAL
BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE
UNITED STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH
TRANSFER, FURNISHES TO U.S. BANK NATIONAL ASSOCIATION, AS TRUSTEE (OR A
SUCCESSOR TRUSTEE, AS APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN
REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE
NOTES (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRUSTEE OR A SUCCESSOR
TRUSTEE, AS APPLICABLE), AND IF SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE
PRINCIPAL AMOUNT OF NOTES OF LESS THAN $100,000, AN OPINION OF COUNSEL
ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE
SECURITIES ACT, (D) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 UNDER
THE SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY
RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO A
REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES
ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (3)
PRIOR TO SUCH TRANSFER

                                      -15-

<PAGE>

(OTHER THAN A TRANSFER PURSUANT TO CLAUSE (2)(F) ABOVE), IT WILL FURNISH TO U.S.
BANK NATIONAL ASSOCIATION, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE),
SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE TRUSTEE MAY
REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT; AND (4) AGREES THAT IT WILL DELIVER TO EACH
PERSON TO WHOM THIS IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS
LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS NOTE PRIOR TO THE EXPIRATION OF
THE HOLDING PERIOD APPLICABLE TO SALES OF THIS NOTE UNDER RULE 144(K) UNDER THE
SECURITIES ACT (OR ANY SUCCESSOR PROVISION), THE HOLDER MUST CHECK THE
APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH
TRANSFER AND SUBMIT THIS CERTIFICATE TO U.S. BANK NATIONAL ASSOCIATION, AS
TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFEREE IS
AN INSTITUTIONAL ACCREDITED INVESTOR OR IS A PURCHASER WHO IS NOT A UNITED
STATES PERSON, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO U.S. BANK
NATIONAL ASSOCIATION, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH
CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS SUCH TRUSTEE MAY
REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER
OF THE TRANSFER OF THIS NOTE PURSUANT TO CLAUSE (2)(F) ABOVE OR UPON ANY
TRANSFER OF THIS NOTE UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY
SUCCESSOR PROVISION). AS USED HEREIN, THE TERMS "UNITED STATES" AND "U.S.
PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES
ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGIONG RESTRICTION.

         Any Note (or security issued in exchange or substitution therefor) as
to which such restrictions on transfer shall have expired in accordance with
their terms or as to the conditions for removal of the foregoing legend set
forth therein have been satisfied may, upon surrender of such Note for exchange
to the Note registrar in accordance with the provisions of this Section 2.5, be
exchanged for a new Note or Notes, of like tenor and aggregate principal amount,
which shall not bear the restrictive legend required by this Section 2.5(d).

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

                                      -16-

<PAGE>

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

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

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

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

         At such time as all interests in a Global Note have been redeemed,
converted, canceled, exchanged for Notes in certificated form, or transferred to
a transferee who receives Notes in certificated form thereof, such Global Note
shall, upon receipt thereof, be canceled by the Trustee in accordance with
standing procedures and instructions existing between the Depositary and the
Custodian. At any time prior to such cancellation, if any interest in a Global
Note is exchanged for Notes in certificated form, redeemed, converted,
repurchased or canceled, exchanged for Notes in certificated form or transferred
to a transferee who receives Notes in certificated form therefor or any Note in
certificated form is exchanged or transferred for part of a Global Note, the
principal amount of such Global Note shall, in accordance with the standing
procedures and instructions existing between the Depositary and the Custodian,
be appropriately reduced or increased, as the case may be, and an endorsement
shall be made on such Global Note, by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase.

         Each Global Note shall also bear the following legend on the face
thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW

FOR THE CERTIFICATES) 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 REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
THE DEPOSITARY AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. (OR TO SUCH OTHER
ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY), ANY
TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

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

         THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE
UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE
UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, UNITED STATES PERSONS
EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES THAT,
UNTIL THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE COMMON
STOCK EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY
SUCCESSOR PROVISION), (1) IT WILL NOT RESELL OR OTHERWISE TRANSFER THE COMMON
STOCK EVIDENCED HEREBY EXCEPT (A) TO LSI LOGIC CORPORATION OR TO ANY SUBSIDIARY
THEREOF, (B) INSIDE THE UNITED STATES TO A "QUALIFIED INSTITUTIONAL BUYER" (AS
DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C)

IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT) THAT PRIOR TO SUCH
TRANSFER, FURNISHES TO EQUISERVE TRUST COMPANY, N.A., AS TRANSFER AGENT (OR A
SUCCESSOR TRANSFER AGENT, AS APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN
REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE
COMMON STOCK EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM

EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF
AVAILABLE), OR (F) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED
EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE
TIME OF SUCH TRANSFER); (2) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER
PURSUANT TO CLAUSE (1)(F) ABOVE), IT WILL FURNISH TO EQUISERVE TRUST COMPANY,
N.A., AS TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH
CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS IT MAY REASONABLY REQUIRE
TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN
A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT; 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(F) ABOVE) A
NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IF THE PROPOSED TRANSFEREE IS
AN INSTITUTIONAL ACCREDITED INVESTOR OR IS A PURCHASER WHO IS NOT A U.S. PERSON,
THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO EQUISERVE TRUST COMPANY,
N.A. (OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL
OPINIONS OR OTHER INFORMATION AS IT MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH
TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT
SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND
WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED
HEREBY PURSUANT TO CLAUSE (1)(F) ABOVE OR UPON ANY TRANSFER OF THE COMMON STOCK
EVIDENCED HEREBY AFTER THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES
OF THE SECURITY EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR
ANY SUCCESSOR PROVISION). AS USED HEREIN, THE TERMS "UNITED STATES" AND "U.S.
PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES
ACT.

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

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

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

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

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

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

         SECTION 2.8 CANCELLATION OF NOTES PAID, ETC. All Notes surrendered for
the purpose of payment, repurchase, conversion, exchange or registration of
transfer, shall, if surrendered to the Company or any paying agent or any Note
registrar or any conversion agent, be surrendered to the Trustee and promptly
canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by
it, and no Notes shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Indenture. The Trustee shall return such
canceled Notes to the Company. If the Company shall acquire any of the Notes,
such acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Notes unless and until the same are delivered
to the Trustee for cancellation.

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

         SECTION 2.10 NO COMPANY REDEMPTION. The Company may not redeem the
Notes prior to the final maturity date of the Notes.

                                  ARTICLE III

                  REPURCHASE OF NOTES UPON A FUNDAMENTAL CHANGE

         SECTION 3.1 REPURCHASE AT OPTION OF HOLDERS.

                  (a) If there shall occur a Fundamental Change, then each
Noteholder shall have the right, at such holder's option, to require the Company
to repurchase all of such holder's Notes, or any portion thereof that is an
integral multiple of $1,000 principal amount, on the date (the "Repurchase
Date") that is thirty (30) days after the date of the Company Notice (as defined
in Section 3.1(b) below) of such Fundamental Change (or, if such 30th day is not
a Business Day, the next succeeding Business Day). Such repayment shall be made
at a repurchase price equal to 100% of the principal amount to be repurchased.
The Company shall also pay to such holders accrued but unpaid interest on the
repurchased Notes to, but excluding, the Repurchase Date; provided that, if such
Repurchase Date is May 15 or November 15, then the interest payable on such date
shall be paid to the holders of record of the Notes on the next preceding May 1
or November 1, respectively.

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

                  (b) On or before the tenth day after the occurrence of a
Fundamental Change, the Company, or, at its written request (which must be
received by the Trustee at least five (5) Business Days prior to the date the
Trustee is requested to give notice as described below), the Trustee in the name
of and at the expense of the Company, shall mail or cause to be mailed to all
holders of record on the date of the Fundamental Change a notice (the "Company
Notice") of the occurrence of such Fundamental Change and of the repurchase
right at the option of the holders arising as a result thereof. The notice shall
be mailed to the holders of the Notes at their last addresses as the same appear
on the Note register. Such mailing shall be by first class mail. The notice if
mailed in the manner herein provided shall be conclusively presumed to have been
duly given, whether or not the holder receives such notice. In any case, failure
to give such notice by mail or any defect in the notice to the holder of any
Note subject to a repurchase right and shall not affect the validity of the
proceedings for the repurchase of any other Note. The Company shall also deliver
a copy of the Company Notice to the Trustee at such time as it is mailed to
Noteholders.

         Each Company Notice shall specify the circumstances constituting the
Fundamental Change, the Repurchase Date, the latest time (not less than thirty
(30) days after the date of the Company's notice of a Fundamental Change) on the
Repurchase Date by which the holder must exercise the repurchase right (the
"Fundamental Change Expiration Time"), that the holder shall have the right to
withdraw any Notes surrendered prior to the Fundamental Change Expiration Time,
a description of the procedure which a Noteholder must follow to exercise such
repurchase right and to withdraw any

                                      -22-

<PAGE>

surrendered Notes, the place or places where the holder is to surrender such
holder's Notes, and the amount of unpaid interest accrued on each Note to the
Repurchase Date.

         No failure of the Company to give the foregoing notices and no defect
therein shall limit the Noteholders' repurchase rights or affect the validity of
the proceedings for the repurchase of the Notes pursuant to this Section 3.1.

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

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

                  (e) In the case of a reclassification, change, consolidation,
merger, combination, sale or conveyance to which Section 15.6 applies, in which
the Common Stock of the Company is changed or exchanged as a result into the
right to receive stock, securities or other property or assets (including cash),
which includes shares of Common Stock of the Company or another person that are,
or upon issuance will be, traded on a United States national securities exchange
or approved for trading on an established automated over-the-counter trading
market in the United States and such shares constitute at the time such change
or exchange becomes effective in excess of 50% of the aggregate fair market
value of such stock, securities or other property or assets (including cash)
into which the Common Stock of the Company is or is to be changed or exchanged
or (as determined by the Company, which determination shall be conclusive and
binding), then the person formed by such consolidation or resulting from such
merger or which acquires such assets, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture (accompanied by an Opinion of
Counsel that such supplemental indenture complies with the Trust Indenture Act
as in force at the date of execution of such supplemental indenture) modifying
the provisions of this Indenture relating to the right of holders of the Notes
to cause the Company to repurchase the Notes following a Fundamental Change,
including without limitation the applicable provisions of this Section 3.1 and
the definitions

                                      -23-

<PAGE>

of Common Stock and Fundamental Change, as appropriate, as determined in good
faith by the Company (which determination shall be conclusive and binding), to
make such provisions apply to such other person if different from the Company
and the common stock issued thereby (in lieu of the Company and the Common Stock
of the Company).

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

                                   ARTICLE IV

                             SUBORDINATION OF NOTES

         SECTION 4.1 NOTES SUBORDINATED TO SENIOR DEBT. The Company covenants
and agrees, and each Holder of Notes, by his acceptance thereof, likewise
covenants and agrees, that the indebtedness represented by the Notes and the
payment of the principal of (and premium, if any) and interest on each and all
of the Notes is hereby expressly subordinate and junior, to the extent and in
the manner hereinafter set forth, in right of payment to the prior payment in
full of all Senior Debt.

                  (a) In the event of any distribution of assets of the Company
upon any dissolution, winding up, liquidation or reorganization of the Company,
whether in bankruptcy, insolvency, reorganization or receivership proceedings or
upon an assignment for the benefit of creditors or any other marshaling of the
assets and liabilities of the Company or otherwise, then the holders of all
Senior Debt shall first be entitled to receive payment of the full amount due
thereon in cash or other consideration satisfactory to the holders of Senior
Debt in respect of principal (and premium, if any) and interest, or provision
shall be made for such amount in money or money's worth, before the Holders of
any of the Notes are entitled to receive any payment or distribution of any
character, whether in cash, securities or other property, on account of the
principal of (or premium, if any) or interest on the indebtedness evidenced by
the Notes.

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

                                      -24-

<PAGE>

4.1(a) if such other person shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions stated in Article XII.

                  (b) In the event of any default in payment of the principal of
or premium, if any, or interest on, rent under, or any other payment obligation
under any Senior Debt (a "Payment Default") beyond any applicable grace period
with respect thereto, then, unless and until all such payments due in respect of
such Senior Debt have been paid in full in cash or other consideration
satisfactory to holders of Senior Debt or such default shall have been cured or
waived or shall have ceased to exist, no payment shall be made by the Company
with respect to the principal of, premium, if any, or interest on the Notes or
to acquire any of the Notes (including any repurchase pursuant to the repurchase
right of a Holder upon a Fundamental Change).

                  (c) In the event (i) any event of default, other than a
payment default, with respect to any Designated Senior Debt shall have occurred
and be continuing permitting the holders of such Designated Senior Debt (or a
trustee or other representative on behalf of the holders thereof) to declare
such Designated Senior Debt due and payable prior to the date on which it would
otherwise have become due and payable, upon written notice thereof to the
Company and the Trustee by any holders of such Designated Senior Debt (or a
trustee or other representative on behalf of the holders thereof) (the "Default
Notice"), unless and until such event of default shall have been cured or waived
or shall have ceased to exist and such acceleration shall have been rescinded or
annulled, or (ii) any judicial proceeding shall be pending with respect to any
such default in payment or event of default, then no payment shall be made by
the Company, directly or indirectly, with respect to principal of, premium, if
any, or interest on the Notes (including any repurchase pursuant to the exercise
of the repurchase right of a Holder upon a Fundamental Change) provided,
however, that clause (i) of this paragraph shall not prevent the making of any
such payment by the Company with respect to the Notes for more than 179 days
after a Default Notice shall have been received by the Trustee unless the
Designated Senior Debt in respect of which such event of default exists has been
declared due and payable in its entirety in which case no such payment may be
made until such acceleration has been rescinded or annulled or such Designated
Senior Debt has been paid in full. Notwithstanding the foregoing, no event of
default which existed or was continuing on the date of any Default Notice shall
be made the basis for the giving of a second Default Notice; provided, further,
however, that no subsequent Default Notice shall be effective for purposes of
this Section 4.1(c) unless and until at least 365 days shall have elapsed since
the initial effectiveness of the immediately prior Default Notice.

                  (d) If the maturity of the Notes is accelerated, no payment
may be made on the Notes until all amounts due or to become due on Senior Debt
has been paid in full in cash or other consideration satisfactory to holders of
Senior Debt or until such acceleration has been cured or waived.

                  (e) In the event that, notwithstanding the foregoing
provisions of Sections 4.1(a), (b), (c) and (d), any payment on account of
principal of or interest on the Notes shall be made by or on behalf of the
Company and received by the Trustee, by any Holder or by any Paying Agent (or,
if the

                                      -25-

<PAGE>

Company is acting as its own Paying Agent, money for any such payment shall be
segregated and held in trust), at a time when such payment is not permitted by
any of such provisions, then, unless and until all Senior Debt (or Designated
Senior Debt, in the case of Section 4.1(c)) is paid in full in cash or other
consideration satisfactory to the holders thereof, or such payment is otherwise
permitted to be made by the provisions of each of Sections 4.1(a), 4.1(b),
4.1(c) and 4.1(d) (subject, in each case, to the provisions of Section 4.7),
such payment on account of principal of or interest on the Notes shall be held
in trust for the benefit of, and shall be immediately paid over to, the holders
of Senior Debt (or Designated Senior Debt, in the case of Section 4.1(c)) or
their representative or representatives or the trustee or trustees under any
indenture under which any instruments evidencing any of the Senior Debt (or
Designated Senior Debt, in the case of Section 4.1(c)) may have been issued, as
their interests may appear.

         Regardless of anything to the contrary herein, nothing shall prevent
any payment by the Trustee to the Holders of amounts deposited with it pursuant
to Sections 4.1 and 4.2.

         SECTION 4.2 SUBROGATION. Subject to the payment in full of all Senior
Debt to which the indebtedness evidenced by the Notes is in the circumstances
subordinated as provided in Section 4.1, the Holders of the Notes (together with
the holders of any other indebtedness of the Company which is subordinate in
right of payment to the payment in full of all Senior Debt, which is not
subordinate in right of payment to the Notes and which by its terms grants such
right of subrogation to the holders thereof) shall be subrogated to the rights
of the holders of such Senior Debt to receive payments or distributions of cash,
property or securities of the Company applicable to such Senior Debt until all
amounts owing on the Notes shall be paid in full, and, as between the Company,
its creditors other than holders of such Senior Debt, and the Holders of the
Notes, no such payment or distribution made to the holders of Senior Debt by
virtue of this Article which otherwise would have been made to the Holders of
the Notes shall be deemed to be a payment by the Company on account of such
Senior Debt, it being understood that the provisions of this Article are and are
intended solely for the purpose of defining the relative rights of the Holders
of the Notes, on the one hand, and the holders of Senior Debt, on the other
hand.

         SECTION 4.3 OBLIGATION OF COMPANY UNCONDITIONAL. Nothing contained in
this Article or elsewhere in this Indenture or in the Notes is intended to or
shall impair, as between the Company, its creditors other than the holders of
Senior Debt, and the Holders of the Notes, the obligation of the Company, which
is absolute and unconditional, to pay to the Holders of the Notes the principal
of (and premium, if any) and interest on the Notes as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders of the Notes and creditors of
the Company other than the holders of Senior Debt, nor shall anything herein or
therein prevent the Trustee or the Holder of any Note from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article of the holders of
Senior Debt in respect of cash, property or securities of the Company received
upon the exercise of any such remedy.

                                      -26-

<PAGE>

         SECTION 4.4 MODIFICATION OF TERMS OF SENIOR DEBT. Any renewal or
extension of the time of payment of any Senior Debt or the exercise by the
holders of Senior Debt of any of their rights under any instrument creating or
evidencing Senior Debt, including without limitation the waiver of default
thereunder, may be made or done all without notice to or assent from the Holders
of the Notes or the Trustee.

         No compromise, alteration, amendment, modification, extension, renewal
or other change of, or waiver, consent or other action in respect of, any
liability or obligation under or in respect of, or of any of the terms,
covenants or conditions of any indenture or other instrument under which any
Senior Debt is outstanding or of such Senior Debt, whether or not such release
is in accordance with the provisions of any applicable document, shall in any
way alter or affect any of the provisions of this Article or of the Notes
relating to the subordination thereof

         SECTION 4.5 PAYMENTS ON NOTES PERMITTED. Nothing contained in this
Article or elsewhere in this Indenture, or in any of the Notes, shall affect the
obligation of the Company to make, or prevent the Company from making, payments
of the principal of, or premium, if any, or interest on the Notes in accordance
with the provisions hereof and thereof, or shall prevent the Trustee or any
Paying Agent from applying any moneys deposited with it hereunder to the payment
of the principal of, or premium, if any, or interest on the Notes, in each case
except as otherwise provided in this Article.

         SECTION 4.6 EFFECTUATION OF SUBORDINATION BY TRUSTEE. Each Holder of
Notes, by his acceptance thereof, authorizes and directs the Trustee in his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee and the Holders of the Notes shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction in
which any such dissolution, winding up, liquidation or reorganization proceeding
affecting the affairs of the Company is pending or upon a certificate of the
trustee in bankruptcy, receiver, assignee for the benefit of creditors,
liquidating trustee or agent or other Person making any payment or distribution,
delivered to the Trustee or to the Holders of the Notes, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, and as to other facts pertinent to the right of such Persons under
this Article, and if such evidence is not furnished, the Trustee may defer any
payment to such Persons pending judicial determination as to the right of such
Persons to receive such payment.

         SECTION 4.7 KNOWLEDGE OF TRUSTEE. Notwithstanding the provisions of
this Article or any other provisions of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any Senior Debt, of any default in
payment of principal, premium (if any) or interest on any Senior Debt, or of any
facts which would prohibit the making of any payment of moneys to or by the
Trustee, or the taking of any other action by the Trustee, unless and until a
Responsible Officer of the Trustee having responsibility for the administration
of the trust established by this Indenture shall

                                      -27-

have received written notice thereof from the Company, any Holder of Notes, any
Paying or Conversion Agent of the Company or the holder or representative of any
class of Senior Debt, and, prior to the receipt of any such written notice, the
Trustee shall be entitled in all respects to assume that no such default or
facts exist; provided, however, that unless on the third Business Day prior to
the date upon which by the terms hereof any such moneys may become payable for
any purpose (other than a payment under Article III) the Trustee shall have
received the notice provided for in this Section 4.7, then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such moneys and apply the same to the purpose for which
they were received, and shall not be affected by any notice to the contrary
which may be received by it on or after such date.

         SECTION 4.8 TRUSTEE'S RELATION TO SENIOR DEBT. The Trustee shall be
entitled to all the rights set forth in this Article with respect to any Senior
Debt at the time held by it, to the same extent as any other holder of Senior
Debt and nothing in this Indenture shall deprive the Trustee of any of its
rights as such holder.

         Nothing in this Article shall apply to claims of or payments to the
Trustee under or pursuant to Section 8.6.

         With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article, and no implied covenants or obligations
with respect to the holders of Senior Debt shall be read into this Indenture
against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty
to the holders of Senior Debt and the Trustee shall not be liable to any holder
of Senior Debt if it shall pay over or deliver to Holders, the Company or any
other Person moneys or assets to which any holder of Senior Debt shall be
entitled by virtue of this Article or otherwise.

         SECTION 4.9 RIGHTS OF HOLDERS OF SENIOR DEBT NOT IMPAIRED. No right of
any present or future holder of any Senior Debt to enforce the subordination
herein shall at any time or in any way be prejudiced or impaired by any act or
failure to act on the part of the Company 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.

         SECTION 4.10 CERTAIN CONVERSIONS NOT DEEMED PAYMENT. For the purposes
of this Article IV only, (1) the issuance and delivery of junior securities upon
conversion of Notes in accordance with Article XV shall not be deemed to
constitute a payment or distribution on account of the principal of, premium, if
any, or interest (including Additional Interest, if any) on Notes or on account
of the purchase or other acquisition of Notes, and (2) the payment, issuance or
delivery of cash (except in satisfaction of fractional shares pursuant to
Section 15.2), property or securities (other than junior securities) upon
conversion of a Note shall be deemed to constitute payment on account of the
principal of, premium, if any, or interest (including Additional Interest, if
any) on such Note. For the purposes of this Section 4.10, the term "junior
securities" means (a) shares of any stock of any class of the Company or (b)
securities of the Company that are subordinated in right of

                                      -28-

<PAGE>

payment to all Senior Debt to substantially the same extent as, or to a greater
extent than, the Notes are so subordinated as provided in this Article. Nothing
contained in this Article IV or elsewhere in this Indenture or in the Notes is
intended to or shall impair, as among the Company, its creditors (other than
holders of Senior Debt) and the Holders, the right, which is absolute and
unconditional, of the holder of any Note to convert such note in accordance with
Article XV.

                                   ARTICLE V

                       PARTICULAR COVENANTS OF THE COMPANY

         SECTION 5.1 PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. The Company
covenants and agrees that it will duly and punctually pay or cause to be paid
the principal of and premium, if any (including upon repurchase pursuant to
Article III), and interest (including Additional Interest, if any) on each of
the Notes at the places, at the respective times and in the manner provided
herein and in the Notes. Each installment of interest on the Notes due on any
semi-annual interest payment date may be paid either (i) by check mailed to the
address of the person entitled thereto as it appears in the Note register;
provided that the holder of Notes with an aggregate principal amount in excess
of $10,000,000 shall, at the written election of such holder, be paid by wire
transfer in immediately available funds; or (ii) by transfer to an account
maintained by such person located in the United States; provided, however, that
payments to the Depositary will be made by wire transfer of immediately
available funds to the account of the Depositary or its nominee.

         SECTION 5.2 MAINTENANCE OF OFFICE OR AGENCY. The Company will maintain
an office or agency in The Borough of Manhattan, The City of New York, where the
Notes may be surrendered for registration of transfer or exchange or for
presentation for payment or for conversion or repurchase and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be
served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency not
designated or appointed by the Trustee. 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 or the office or agency of
the Trustee in The Borough of Manhattan, The City of New York (which shall
initially be located at U.S. Bank Trust National Association, 100 Wall Street,
Suite 1600, New York, NY 10005, Attention: Corporate Trust Services (LSI Logic
Corporation 4% Convertible Subordinated Notes due 2010)).

         The Company may also from time to time designate co-registrars and one
or more other offices or agencies where the Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations. The Company will give prompt written notice to any such
designation or rescission and of any change in the location of any such other
office or agency.

         The Company hereby initially designates the Trustee as paying agent,
Note registrar, Custodian and conversion agent and each of the Corporate Trust
Office of the Trustee and the office

                                      -29-

<PAGE>

or agency of the Trustee in The Borough of Manhattan, The City of New York
(which shall initially be located at U.S. Bank Trust National Association, 100
Wall Street, Suite 1600, New York, NY 10005, Attention: Corporate Trust Services
(LSI Logic Corporation 4% Convertible Subordinated Notes due 2010)), shall be
considered as one such office or agency of the Company for each of the aforesaid
purposes.

         So long as the Trustee is the Note registrar, the Trustee agrees to
mail, or cause to be mailed, the notices set forth in Section 8.10(a) and the
third paragraph of Section 8.11. If co-registrars have been appointed in
accordance with this Section, the Trustee shall mail such notices only to the
Company and the holders of Notes it can identify from its records.

         SECTION 5.3 APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 8.10, a Trustee, so that there
shall at all times be a Trustee hereunder.

         SECTION 5.4 PROVISIONS AS TO PAYING AGENT.

                  (a) If the Company shall appoint a paying agent other than the
Trustee, or if the Trustee shall appoint such a paying agent, it will cause such
paying agent to execute and deliver to the Trustee an instrument in which such
agent shall agree with the Trustee, subject to the provisions of this Section
5.4:

                           (i)      that it will hold all sums held by it as
such agent for the payment of the principal of and premium, if any, or interest
on the Notes (whether such sums have been paid to it by the Company or by any
other obligor on the Notes) in trust for the benefit of the holders of the
Notes;

                           (ii)     that it will give the Trustee notice of any
failure by the Company (or by any other obligor on the Notes) to make any
payment of the principal of and premium, if any, or interest on the Notes when
the same shall be due and payable; and

                           (iii)     that at any time during the continuance of
an Event of Default, upon request of the Trustee, it will forthwith pay to the
Trustee all sums so held in trust.

         The Company shall, on or before each due date of the principal of,
premium, if any, or interest on the Notes, deposit with the paying agent a sum
in good funds sufficient to pay such principal, premium, if any, or interest,
and (unless such paying agent is the Trustee) the Company will promptly notify
the Trustee of any failure to take such action; provided that if such deposit is
made on the due date, such deposit shall be received by the paying agent by
10:00 a.m. New York City time, on such date.

                  (b) If the Company shall act as its own paying agent, it will,
on or before each due date of the principal of, premium, if any, or interest
(including Additional Interest, if any) on the Notes, set aside, segregate and
hold in trust for the benefit of the holders of the Notes a sum

                                      -30-

<PAGE>

sufficient to pay such principal, premium, if any, or interest (including
Additional Interest, if any) so becoming due and promptly will notify the
Trustee of any failure to take such action and of any failure by the Company (or
any other obligor under the Notes) to make any payment of the principal of,
premium, if any, or interest (including Additional Interest, if any) on the
Notes when the same shall become due and payable.

                  (c) Anything in this Section 5.4 to the contrary
notwithstanding, the Company may, at any time, for the purpose of obtaining a
satisfaction and discharge of this Indenture, or for any other reason, pay or
cause to be paid to the Trustee all sums held in trust by the Company or any
paying agent hereunder as required by this Section 5.4, such sums to be held by
the Trustee upon the trusts herein contained and upon such payment by the
Company or any paying agent to the Trustee, the Company or such paying agent
shall be released from all further liability with respect to such sums.

                  (d) Anything in this Section 5.4 to the contrary
notwithstanding, the agreement to hold sums in trust as provided in this Section
5.4 is subject to Sections 13.3 and 13.4.

         The Trustee shall not be responsible for the actions of any other
paying agents (including the Company if acting as its own paying agent) and
shall have no control of any funds held by such other paying agents.

         SECTION 5.5 EXISTENCE. Subject to Article XII, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its existence and rights (charter and statutory); provided, however, that
the Company shall not be required to preserve any such right if the Company
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 5.6 MAINTENANCE OF PROPERTIES. The Company will cause all
properties used or useful in the conduct of its business or the business of any
Significant Subsidiary to be maintained and kept in good condition, repair and
working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent the Company from discontinuing the operation or maintenance of any of
such properties if such discontinuance is, in the judgment of the Company,
desirable in the conduct of its business or the business of any subsidiary and
not disadvantageous in any material respect to the holders.

         SECTION 5.7 PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay or
discharge, or cause to be paid or discharged, before the same may become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Significant Subsidiary or upon the income,
profits or property of the Company or any Significant Subsidiary, (ii) all
claims for labor, materials and supplies which, if unpaid, might by law become a
lien or

                                      -31-

<PAGE>

charge upon the property of the Company or any Significant Subsidiary and (iii)
all stamps and other duties, if any, which may be imposed by the United States
or any political subdivision thereof or therein in connection with the issuance,
transfer, exchange or conversion of any Notes or with respect to this Indenture;
provided, however, that, in the case of clauses (i) and (ii), the Company shall
not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim (A) if the failure to do so will not, in the
aggregate, have a material adverse impact on the Company, or (B) if the amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

         SECTION 5.8 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 holder of Notes or any Common Stock issued upon conversion thereof
which continue to be Restricted Securities in connection with any sale thereof
and any prospective purchaser of Notes or such Common Stock from such holder or
beneficial holder, the information required pursuant to Rule 144A(d)(4) under
the Securities Act upon the request of any holder or beneficial holder of the
Notes or such Common Stock and it will take such further action as any holder or
beneficial holder of such Notes or such Common Stock may reasonably request, all
to the extent required from time to time to enable such holder or beneficial
holder to sell its Notes or Common Stock 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. Upon the request of any holder or
any beneficial holder of the Notes or such Common Stock, the Company will
deliver to such holder a written statement as to whether it has complied with
such requirements.

         SECTION 5.9 STAY, EXTENSION AND USURY LAWS. The Company covenants (to
the extent that it may lawfully do so) that it shall not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law or other law which would prohibit or
forgive the Company from paying all or any portion of the principal of, premium,
if any, or interest (including Additional Interest, if any) on the Notes as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture, and the
Company (to the extent it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not, by resort
to any such law, hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

         SECTION 5.10 COMPLIANCE CERTIFICATE. The Company shall deliver to the
Trustee, within one hundred twenty (120) days after the end of each fiscal year
of the Company, a certificate signed by either the principal executive officer,
principal financial officer or principal accounting officer of the Company,
stating whether or not to the best knowledge of the signer thereof the Company
is in default in the performance and observance of any of the terms, provisions
and conditions of this Indenture (without regard to any period of grace or
requirement of notice provided

                                      -32-

<PAGE>

hereunder) and, if the Company shall be in default, specifying all such defaults
and the nature and status thereof of which the signer may have knowledge.

         The Company will deliver to the Trustee, forthwith upon becoming aware
of any default in the performance or observance of any covenant, agreement or
condition contained in this Indenture, or any Event of Default, an Officers'
Certificate specifying with particularity such default or Event of Default and
further stating what action the Company has taken, is taking or proposes to take
with respect thereto.

         Any notice required to be given under this Section 5.10 shall be
delivered to the Trustee at its Corporate Trust Office.

         SECTION 5.11 ADDITIONAL INTEREST. If Additional Interest is payable by
the Company pursuant to the Registration Rights Agreement, the Company shall
deliver to the Trustee a certificate to the effect stating (i) the amount of
such Additional Interest that is payable and (ii) the date on which such
interest is payable. Unless and until a Responsible Officer of the Trustee
receives such certificate, the Trustee may assume without inquiry that no
Additional Interest is payable. If the Company has paid Additional Interest
directly to the persons entitled to such interest, the Company shall deliver to
the Trustee a certificate setting forth the particulars of such payment.

                                   ARTICLE VI

          NOTEHOLDERS' LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

         SECTION 6.1 NOTEHOLDERS' LISTS. The Company covenants and agrees that
it will furnish or cause to be furnished to the Trustee, semiannually, not more
than fifteen (15) days after each May 1 and November 1 in each year beginning
with November 1, 2003, and at such other times as the Trustee may request in
writing, within thirty (30) days after receipt by the Company of any such
request (or such lesser time as the Trustee may reasonably request in order to
enable it to timely provide any notice to be provided by it hereunder), a list
in such form as the Trustee may reasonably require of the names and addresses of
the holders of Notes as of a date not more than fifteen (15) days (or such other
date as the Trustee may reasonably request in order to so provide any such
notices) prior to the time such information is furnished, except that no such
list need be furnished by the Company to the Trustee so long as the Trustee is
acting as the sole Note registrar.

         SECTION 6.2 PRESERVATION AND DISCLOSURE OF LISTS.

                  (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the
holders of Notes contained in the most recent list furnished to it as provided
in Section 6.1 or maintained by the Trustee in its capacity as Note registrar or
co-registrar in respect of the Notes, if so acting. The Trustee may destroy any
list furnished to it as provided in Section 6.1 upon receipt of a new list so
furnished.

                                      -33-

<PAGE>

                  (b) The rights of Noteholders to communicate with other
holders of Notes with respect to their rights under this Indenture or under the
Notes, and the corresponding rights and duties of the Trustee, shall be as
provided by the Trust Indenture Act.

                  (C) Every Noteholder, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of any
disclosure of information as to names and addresses of holders of Notes made
pursuant to the Trust Indenture Act.

         SECTION 6.3 REPORTS BY TRUSTEE.

                  (a) Within sixty (60) days after May 15 of each year
commencing with the year 2004, the Trustee shall transmit to holders of Notes
such reports dated as of May 15 of the year in which such reports are made
concerning the Trustee and its actions under this Indenture as may be required
pursuant to the Trust Indenture Act at the times and in the manner provided
pursuant thereto.

                  (b) A copy of such report shall, at the time of such
transmission to holders of Notes, be filed by the Trustee with each stock
exchange and automated quotation system upon which the Notes are listed and with
the Company. The Company will notify the Trustee in writing within a reasonable
time when the Notes are listed on any stock exchange or automated quotation
system or delisted therefrom.

         SECTION 6.4 REPORTS BY COMPANY. The Company shall file with the Trustee
(and the Commission if at any time after the Indenture becomes qualified under
the Trust Indenture Act), and transmit to holders of Notes, such information,
documents and other reports and such summaries thereof, as may be required
pursuant to the Trust Indenture Act at the times and in the manner provided
pursuant to such Act, whether or not the Notes are governed by such Act;
provided that any such information, documents or reports required to be filed
with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be
filed with the Trustee within fifteen (15) days after the same is so required to
be filed with the Commission. Delivery of such reports, information and
documents to the Trustee is for informational purposes only and the Trustee's
receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

                                  ARTICLE VII

        REMEDIES OF THE TRUSTEE AND NOTEHOLDERS UPON AN EVENT OF DEFAULT

         SECTION 7.1 EVENTS OF DEFAULT. In case one or more of the following
Events of Default (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body) shall have occurred and be
continuing:

                                      -34-

<PAGE>

                  (a) default in the payment of any installment of interest
(including Additional Interest, if any) upon any of the Notes as and when the
same shall become due and payable, and continuance of such default for a period
of thirty (30) days, whether or not such payment is permitted under Article IV
hereof; or

                  (b) default in the payment of the principal of or premium, if
any, on any of the Notes as and when the same shall become due and payable
either at maturity or in connection with any repurchase pursuant to Article III,
by acceleration or otherwise, whether or not such payment is permitted under
Article IV hereof; or

                  (c) failure on the part of the Company duly to observe or
perform any other of the covenants or agreements on the part of the Company in
the Notes or in this Indenture (other than a covenant or agreement a default in
whose performance or whose breach is elsewhere in this Section 7.1 specifically
dealt with) continued for a period of sixty (60) days after the date on which
written notice of such failure, requiring the Company to remedy the same, shall
have been given to the Company by the Trustee, or to the Company and a
Responsible Officer of the Trustee by the holders of at least twenty-five
percent (25%) in aggregate principal amount of the Notes at the time outstanding
determined in accordance with Section 9.4; or

                  (d) the Company shall commence a voluntary case or other
proceeding seeking liquidation, reorganization or other relief with respect to
the Company or its debts under any bankruptcy, insolvency or other similar law
now or hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of it or any substantial part of
the property of the Company, or shall consent to any such relief or to the
appointment of or taking possession by any such official in an involuntary case
or other proceeding commenced against it, or shall make a general assignment for
the benefit of creditors, or shall fail generally to pay its debts as they
become due; or

                  (e) an involuntary case or other proceeding shall be commenced
against the Company seeking liquidation, reorganization or other relief with
respect to it or its debts under any bankruptcy, insolvency or other similar law
now or hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of it or any substantial part of
the property of the Company, and such involuntary case or other proceeding shall
remain undismissed and unstayed for a period of ninety (90) consecutive days;

         then, and in each and every such case (other than an Event of Default
specified in Section 7.1 (d) or (e)), unless the principal of all of the Notes
shall have already become due and payable, either the Trustee or the holders of
not less than twenty-five percent (25%) in aggregate principal amount of the
Notes then outstanding hereunder determined in accordance with Section 9.4, by
notice in writing to the Company (and to the Trustee if given by Noteholders),
may declare the principal of and premium, if any, on all the Notes and the
unpaid interest accrued thereon (including Additional Interest, if any) to be
due and payable immediately, and upon any such declaration the same shall become
and shall be immediately due and payable, anything in this Indenture or in the
Notes contained to the contrary notwithstanding. If an Event of Default
specified in Section 7.1(d) or (e)

                                      -35-

<PAGE>

occurs, the principal of all the Notes and the unpaid interest accrued thereon
shall (including Additional Interest, if any) be immediately and automatically
due and payable without necessity of further action. This provision, however, is
subject to the conditions that if, at any time after the principal of the Notes
shall have been so declared due and payable, and before any judgment or decree
for the payment of the monies due shall have been obtained or entered as
hereinafter provided, the Company shall pay or shall deposit with the Trustee a
sum sufficient to pay all matured installments of interest upon (including
Additional Interest, if any) all Notes and the principal of and premium, if any,
on any and all Notes which shall have become due otherwise than by acceleration
(with interest on overdue installments of interest (including Additional
Interest, if any) (to the extent that payment of such interest is enforceable
under applicable law) and on such principal and premium, if any, at the rate
borne by the Notes, to the date of such payment or deposit) and amounts due to
the Trustee pursuant to Section 8.6, and if any and all defaults under this
Indenture, other than the nonpayment of principal of and premium, if any, and
accrued but unpaid interest on (including Additional Interest, if any) Notes
which shall have become due by acceleration, shall have been cured or waived
pursuant to Section 7.7, then and in every such case the holders of a majority
in aggregate principal amount of the Notes then outstanding, by written notice
to the Company and to the Trustee, may waive all defaults or Events of Default
and rescind and annul such declaration and its consequences; but no such waiver
or rescission and annulment shall extend to or shall affect any subsequent
default or Event of Default, or shall impair any right consequent thereon. The
Company shall notify a Responsible Officer of the Trustee in writing, promptly
upon becoming aware thereof, of any Event of Default.

         In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such waiver or rescission and annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the Company, the holders of Notes, and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the holders of Notes, and the Trustee shall
continue as though no such proceeding had been taken.

         SECTION 7.2 PAYMENTS OF NOTES ON DEFAULT; SUIT THEREFOR. The Company
covenants that (a) in case default shall be made in the payment of any
installment of interest upon (including Additional Interest, if any) any of the
Notes as and when the same shall become due and payable, and such default shall
have continued for a period of thirty (30) days, or (b) in case default shall be
made in the payment of the principal of or premium, if any, on any of the Notes
as and when the same shall have become due and payable, whether at maturity of
the Notes or in connection with any repurchase, by or under this Indenture
declaration or otherwise -- then, upon demand of the Trustee, the Company will
pay to the Trustee, for the benefit of the holders of the Notes, the whole
amount that then shall have become due and payable on all such Notes for
principal and premium, if any, or interest (including Additional Interest, if
any), as the case may be, with interest upon the overdue principal and premium,
if any, and (to the extent that payment of such interest is enforceable under
applicable law) upon the overdue installments of interest (including Additional
Interest, if any) at the rate borne by the Notes; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including reasonable compensation to the Trustee, its agents,

                                      -36-

attorneys and counsel, and other amounts due the Trustee under Section 8.6.
Until such demand by the Trustee, the Company may pay the principal of and
premium, if any, and interest on (including Additional Interest, if any) the
Notes to the registered holders, whether or not the Notes are overdue.

         In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the Notes
and collect in the manner provided by law out of the property of the Company or
any other obligor on the Notes wherever situated the monies adjudged or decreed
to be payable.

         In the case there shall be pending proceedings for the bankruptcy or
for the reorganization of the Company or any other obligor on the Notes under
Title 11 of the United States Code, or any other applicable law, or in case a
receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken
possession of the Company or such other obligor, the property of the Company or
such other obligor, or in the case of any other judicial proceedings relative to
the Company or such other obligor upon the Notes, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 7.2, shall
be entitled and empowered, by intervention in such proceedings or otherwise, to
file and prove a claim or claims for the whole amount of principal, premium, if
any, and interest (including Additional Interest, if any) owing and unpaid in
respect of the Notes, and, in case of any judicial proceedings, to file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and of the Noteholders allowed in
such judicial proceedings relative to the Company or any other obligor on the
Notes, its or their creditors, or its or their property, and to collect and
receive any monies or other property payable or deliverable on any such claims,
and to distribute the same after the deduction of any amounts due the Trustee
under Section 8.6; and any receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, custodian or similar official is hereby authorized
by each of the Noteholders to make such payments to the Trustee, and, in the
event that the Trustee shall consent to the making of such payments directly to
the Noteholders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including counsel fees
incurred by it up to the date of such distribution. To the extent that such
payment of reasonable compensation, expenses, advances and disbursements out of
the estate in any such proceedings shall be denied for any reason, payment of
the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, monies, securities and other property which the
holders of the Notes may be entitled to receive in such proceedings, whether in
liquidation or under any plan of reorganization or arrangement or otherwise.

         All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes, or the production thereof

                                      -37-

<PAGE>

at any trial or other proceeding relative thereto, and any such suit or
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 Notes.

         In any proceedings brought by the Trustee (and in any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Notes, and it shall not be necessary to make any holders of the Notes
parties to any such proceedings.

         SECTION 7.3 APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any monies
collected by the Trustee pursuant to this Article VII shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid:

         FIRST: To the payment of all amounts due the Trustee under Section 8.6;

         SECOND: Subject to the provisions of Article IV, in case the principal
of the outstanding Notes shall not have become due and be unpaid, to the payment
of accrued but unpaid interest on (including Additional Interest, if any) the
Notes in default in the order of the maturity of the installments of such
interest, with interest (to the extent that such interest has been collected by
the Trustee) upon the overdue installments of interest (including Additional
Interest, if any) at the rate borne by the Notes, such payments to be made
ratably to the persons entitled thereto;

         THIRD: Subject to the provisions of Article IV, in case the principal
of the outstanding Notes shall have become due, by declaration or otherwise, and
be unpaid to the payment of the whole amount then owing and unpaid upon the
Notes for principal and premium, if any, and accrued but unpaid interest
(including Additional Interest, if any), with interest on the overdue principal
and premium, if any, and (to the extent that such interest has been collected by
the Trustee) upon overdue installments of interest (including Additional
Interest, if any) at the rate borne by the Notes; and in case such monies shall
be insufficient to pay in full the whole amounts so due and unpaid upon the
Notes, then to the payment of such principal and premium, if any, and interest
(including Additional Interest, if any) without preference or priority of
principal and premium, if any, over interest (including Additional Interest, if
any), or of interest (including Additional Interest, if any) over principal and
premium, if any, or of any installment of interest over any other installment of
interest, or of any Note over any other Note, ratably to the aggregate of such
principal and premium, if any, and accrued and unpaid interest; and

         FOURTH: Subject to the provisions of Article IV, to the payment of the
remainder, if any, to the Company or any other person lawfully entitled thereto.

         SECTION 7.4 PROCEEDINGS BY NOTEHOLDER. No holder of any Note shall have
any right by virtue of or by availing of any provision of this Indenture to
institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Indenture, or for the appointment

                                      -38-

<PAGE>

of a receiver, trustee, liquidator, custodian or other similar official, or for
any other remedy hereunder, unless such holder previously shall have given to
the Trustee written notice of an Event of Default and of the continuance
thereof, as hereinbefore provided, and unless also the holders of not less than
twenty-five percent (25%) in aggregate principal amount of the Notes then
outstanding shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and shall have
offered to the Trustee such reasonable indemnity as it may require against the
costs, expenses and liabilities to be incurred therein or thereby, and the
Trustee for sixty (60) days after its receipt of such notice, request and offer
of indemnity, shall have neglected or refused to institute any such action, suit
or proceeding and no direction inconsistent with such written request shall have
been given to the Trustee pursuant to Section 7.7; it being understood and
intended, and being expressly covenanted by the taker and holder of every Note
with every other taker and holder and the Trustee, that no one or more holders
of Notes 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 holder of Notes, or to obtain or seek to obtain priority over or
preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all holders of Notes (except as otherwise provided herein).
For the protection and enforcement of this Section 7.4, each and every
Noteholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

         Notwithstanding any other provision of this Indenture and any provision
of any Note, the right of any holder of any Note to receive payment of the
principal of and premium, if any (including upon repurchase pursuant to Article
III), and accrued interest on (including Additional Interest, if any) such Note,
on or after the respective due dates expressed in such Note or in the event of
repurchase, or to institute suit for the enforcement of any such payment on or
after such respective dates against the Company shall not be impaired or
affected without the consent of such holder.

         Anything in this Indenture or the Notes to the contrary
notwithstanding, the holder of any Note, without the consent of either the
Trustee or the holder of any other Note, in its own behalf and for its own
benefit, may enforce, and may institute and maintain any proceeding suitable to
enforce, its rights of conversion as provided herein.

         SECTION 7.5 PROCEEDINGS BY TRUSTEE. In case of an Event of Default the
Trustee may in its discretion proceed to protect and enforce the rights vested
in it by this Indenture by such appropriate judicial proceedings as are
necessary to protect and enforce any of such rights, either by suit in equity or
by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or
in aid of the exercise of any power granted in this Indenture, or to enforce any
other legal or equitable right vested in the Trustee by this Indenture or by
law.

         SECTION 7.6 REMEDIES CUMULATIVE AND CONTINUING. Except as provided in
Section 2.6, all powers and remedies given by this Article VII to the Trustee or
to the Noteholders shall, to the extent permitted by law, be deemed cumulative
and not exclusive of any thereof or of

                                      -39-

<PAGE>

any other powers and remedies available to the Trustee or the holders of the
Notes, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture, and no
delay or omission of the Trustee or of any holder of any of the Notes to
exercise any right or power accruing upon any default or Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or any acquiescence
therein; and, subject to the provisions of Section 7.4, every power and remedy
given by this Article VII or by law to the Trustee or to the Noteholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Noteholders.

         SECTION 7.7 DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY
OF NOTEHOLDERS. The holders of a majority in aggregate principal amount of the
Notes at the time outstanding determined in accordance with Section 9.4 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; provided, however, 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 which is not inconsistent with such direction and (c)
the Trustee may decline to take any action that would benefit some Noteholder to
the detriment of other Noteholders. The holders of a majority in aggregate
principal amount of the Notes at the time outstanding determined in accordance
with Section 9.4 may on behalf of the holders of all of the Notes waive any past
default or Event of Default hereunder and its consequences except (i) a default
in the payment of interest or premium, if any, on, or the principal of, the
Notes, (ii) a failure by the Company on request to convert any Notes into Common
Stock, (iii) a default in the payment of repurchase price pursuant to Article
III or (iv) a default in respect of a covenant or provisions hereof which under
Article XI cannot be modified or amended without the consent of the holders of
all Notes then outstanding or affected thereby. Upon any such waiver, the
Company, the Trustee and the holders of the Notes shall be restored to their
former positions and rights hereunder; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon. Whenever any default or Event of Default hereunder shall have been
waived as permitted by this Section 7.7, said default or Event of Default shall
for all purposes of the Notes and this Indenture be deemed to have been cured
and to be not continuing; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

         SECTION 7.8 NOTICE OF DEFAULTS. The Trustee shall, within ninety (90)
days after a Responsible Officer of the Trustee has knowledge of the occurrence
of a default, mail to all Noteholders, as the names and addresses of such
holders appear upon the Note register, notice of all defaults known to a
Responsible Officer, unless such defaults shall have been cured or waived before
the giving of such notice; and provided that, except in the case of default in
the payment of the principal of, or premium, if any, or interest (including
Additional Interest, if any) on any of the Notes, the Trustee shall be protected
in withholding such notice if and so long as a trust committee of directors
and/or Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interests of the Noteholders.

         SECTION 7.9 UNDERTAKING TO PAY COSTS. All parties to this Indenture
agree, and each holder of any Note 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; provided that the provisions of this Section 7.9 (to the extent
permitted by law) shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Noteholder, or group of Noteholders, holding in the
aggregate more than ten percent in principal amount of the Notes at the time
outstanding determined in accordance with Section 9.4, or to any suit instituted
by any Noteholder for the enforcement of the payment of the principal of or
premium, if any, or interest on any Note on or after the due date expressed in
such Note or to any suit for the enforcement of the right to convert any Note in
accordance with the provisions of Article XV.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

         SECTION 8.1 DUTIES AND RESPONSIBILITIES OF TRUSTEE. The Trustee, prior
to the occurrence of an Event of Default and after the curing of all Events of
Default which 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 (which has not been cured or waived) the Trustee shall
exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

         No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that

                  (a) prior to the occurrence of an Event of Default and after
the curing or waiving of all Events of Default which may have occurred:

                           (i)      the duties and obligations of the Trustee
shall be determined solely by the express provisions of this Indenture and the
Trust Indenture Act, and the Trustee shall not be liable except for the
performance of such duties and obligations as are specifically set forth in this
Indenture and no implied covenants or obligations shall be read into this
Indenture and the Trust Indenture Act against the Trustee; and

                           (ii)     in the absence of bad faith and willful
misconduct on the part of the Trustee, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed
therein, upon any certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture; but, in the case of any such
certificates or opinions which by any provisions hereof are specifically
required to be furnished to the Trustee, the Trustee

                                      -41-

<PAGE>

shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture;

                  (b) the Trustee shall not be liable for any error of judgment
made in good faith by a Responsible Officer or Officers of the Trustee, unless
the Trustee was negligent in ascertaining the pertinent facts;

                  (c) the Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the written
direction of the holders of not less than a majority in principal amount of the
Notes at the time outstanding determined as provided in Section 9.4 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;

                  (d) whether or not therein provided, every provision of this
Indenture relating to the conduct or affecting the liability of, or affording
protection to, the Trustee shall be subject to the provisions of this Section;

                  (e) the Trustee shall not be liable in respect of any payment
(as to the correctness of amount, entitlement to receive or any other matters
relating to payment) or notice effected by the Company or any paying agent or
any records maintained by any co-registrar with respect to the Notes; and

                  (f) if any party fails to deliver a notice relating to an
event the fact of which, pursuant to this Indenture, requires notice to be sent
to the Trustee, the Trustee may conclusively rely on its failure to receive such
notice as reason to act as if no such event occurred.

         None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

         SECTION 8.2 RELIANCE ON DOCUMENTS, OPINIONS, ETC. Except as otherwise
provided in Section 8.1:

                  (a) the Trustee may rely and shall be protected in acting upon
any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, bond, debenture, note, coupon or other paper or
document believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties;

                  (b) any request, direction, order or demand of the Company
mentioned herein shall be sufficiently evidenced by an Officers' Certificate
(unless other evidence in respect thereof be

                                      -42-

<PAGE>

herein specifically prescribed); and any resolution of the Board of Directors
may be evidenced to the Trustee by a copy thereof certified by the Secretary or
an Assistant Secretary of the Company;

                  (c) the Trustee may consult with counsel and any advice or
Opinion of Counsel shall be full and complete authorization and protection in
respect of any action taken or omitted by it hereunder in good faith and in
accordance with such advice or Opinion of Counsel;

                  (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, order or
direction of any of the Noteholders pursuant to the provisions of this
Indenture, unless such Noteholders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities which may be
incurred therein or thereby;

                  (e) 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 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; and

                  (f) the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys and the Trustee shall not be responsible for any misconduct
or negligence on the part of any agent or attorney appointed by it with due care
hereunder.

         SECTION 8.3 NORESPONSIBILITY FOR RECITALS, ETC. The recitals contained
herein and in the Notes (except in the Trustee's certificate of authentication)
shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Notes. The Trustee shall not be accountable for the use or application by the
Company of any Notes or the proceeds of any Notes authenticated and delivered by
the Trustee in conformity with the provisions of this Indenture.

         SECTION 8.4 TRUSTEE, PAYING AGENTS, CONVERSION AGENTS OR REGISTRAR MAY
OWN NOTES. The Trustee, any paying agent, any conversion agent or Note
registrar, in its individual or any other capacity, may become the owner or
pledgee of Notes with the same rights it would have if it were not Trustee,
paying agent, conversion agent or Note registrar.

         SECTION 8.5 MONIES TO BE HELD IN TRUST. Subject to the provisions of
Section 13.4 and Section 4.2, 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. Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder
except as may be agreed from time to time in writing by the Company and the
Trustee.

                                      -43-

<PAGE>

         SECTION 8.6 COMPENSATION AND EXPENSES OF TRUSTEE. The Company covenants
and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, reasonable compensation for all services rendered by it hereunder
in any capacity (which shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust) as mutually agreed to in
writing between the Company and the Trustee, and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all persons not regularly in its employ) except any such expense, disbursement
or advance as may arise from its negligence, willful misconduct, recklessness or
bad faith. The Company also covenants to indemnify the Trustee (or any officer,
director or employee of the Trustee) in any capacity under this Indenture and
its agents and any authenticating agent for, and to hold them harmless against,
any loss, liability or expense incurred without negligence, willful misconduct,
recklessness, or bad faith on the part of the Trustee or such officers,
directors, employees and agent or authenticating agent, as the case may be, and
arising out of or in connection with the acceptance or administration of this
trust or in any other capacity hereunder, including the costs and expenses of
defending themselves against any claim of liability in the premises. The
obligations of the Company under this Section 8.6 to compensate or indemnify the
Trustee and to pay or reimburse the Trustee for expenses, disbursements and
advances shall be secured by a lien prior to that of the Notes upon all property
and funds held or collected by the Trustee as such, except funds held in trust
for the benefit of the holders of particular Notes. The obligation of the
Company under this Section shall survive the satisfaction and discharge of this
Indenture.

         When the Trustee and its agents and any authenticating agent incur
expenses or render services after an Event of Default specified in Section
7.1(d) or (e) occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under any bankruptcy,
insolvency or similar laws.

         SECTION 8.7 OFFICERS' CERTIFICATE AS EVIDENCE. Except as otherwise
provided in Section 8.1, whenever in the administration of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence, willful misconduct, recklessness,
or bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers' Certificate delivered to the Trustee.

         SECTION 8.8 CONFLICTING INTERESTS OF TRUSTEE. If the Trustee has or
shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, 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 Trust
Indenture Act and this Indenture.

         SECTION 8.9 ELIGIBILITY OF TRUSTEE. There shall at all times be a
Trustee hereunder which shall be a person that is eligible pursuant to the Trust
Indenture Act to act as such and has a

                                      -44-

<PAGE>

combined capital and surplus of at least $50,000,000 (or if such person is a
member of a bank holding company system, its bank holding company shall have a
combined capital and surplus of at least $50,000,000). If such person publishes
reports of condition at least annually, pursuant to law or to the requirements
of any supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such person shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

         SECTION 8.10 RESIGNATION OR REMOVAL OF TRUSTEE.

                  (a) The Trustee may at any time resign by giving written
notice of such resignation to the Company and to the holders of Notes. Upon
receiving such notice of resignation, the Company shall promptly appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors, one copy of which instrument shall be delivered to the
resigning Trustee and one copy to the successor trustee. If no successor trustee
shall have been so appointed and have accepted appointment sixty (60) days after
the mailing of such notice of resignation to the Noteholders, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor trustee, or any Noteholder who has been a bona fide holder of a Note
or Notes for at least six (6) months may, subject to the provisions of Section
7.9, on behalf of himself and all others similarly situated, petition any such
court for the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, appoint a
successor trustee.

                  (b) In case at any time any of the following shall occur:

                           (i)      the Trustee shall fail to comply with
Section 8.8 after written request therefor by the Company or by any Noteholder
who has been a bona fide holder of a Note or Notes for at least six (6) months;
or

                           (ii)     the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.9 and shall fail to resign after
written request therefor by the Company or by any such Noteholder; or

                           (iii)    the Trustee shall become incapable of
acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the
Trustee or of its property shall be appointed, or any public officer shall take
charge or control of the Trustee or of its property or affairs for the purpose
of rehabilitation, conservation or liquidation;

         then, in any such case, the Company may remove the Trustee and appoint
a successor trustee by written instrument, in duplicate, executed by order of
the Board of Directors, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor trustee, or, subject to the
provisions of Section 7.9, any Noteholder who has been a bona fide holder of a
Note or Notes for at least six (6) months may, on behalf of himself and all
others similarly situated, petition

                                      -45-

<PAGE>

any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee; provided that if no successor trustee shall
have been appointed and have accepted appointment sixty (60) days after either
the Company or the Noteholders has removed the Trustee, the Trustee so removed
may petition any court of competent jurisdiction for an appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it
may deem proper and prescribe, remove the Trustee and appoint a successor
trustee.

                  (c) The holders of a majority in aggregate principal amount of
the Notes at the time outstanding may at any time remove the Trustee and
nominate a successor trustee which shall be deemed appointed as successor
trustee unless within ten (10) days after notice to the Company of such
nomination the Company objects thereto, in which case the Trustee so removed or
any Noteholder, or if such Trustee so removed or any Noteholder fails to act,
the Company, upon the terms and conditions and otherwise as in Section 8.10(a)
provided, may petition any court of competent jurisdiction for an appointment of
a successor trustee.

                  (d) Any resignation or removal of the Trustee and appointment
of a successor trustee pursuant to any of the provisions of this Section 8.10
shall become effective upon acceptance of appointment by the successor trustee
as provided in Section 8.11.

         SECTION 8.11 ACCEPTANCE BY SUCCESSOR TRUSTEE. Any successor trustee
appointed as provided in Section 8.10 shall execute, acknowledge and deliver to
the Company and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee herein; but, nevertheless, on the written request
of the Company or of the successor trustee, the trustee ceasing to act shall,
upon payment of any amounts then due it pursuant to the provisions of Section
8.6, execute and deliver an instrument transferring to such successor trustee
all the rights and powers of the trustee so ceasing to act. Upon request of any
such successor trustee, the Company shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a lien upon all property and funds held or collected by
such trustee as such, except for funds held in trust for the benefit of holders
of particular Notes, to secure any amounts then due it pursuant to the
provisions of Section 8.6.

         No successor trustee shall accept appointment as provided in this
Section 8.11 unless at the time of such acceptance such successor trustee shall
be qualified under the provisions of Section 8.8 and be eligible under the
provisions of Section 8.9.

         Upon acceptance of appointment by a successor trustee as provided in
this Section 8.11, the Company (or the former trustee, at the written direction
of the Company) shall mail or cause to be mailed notice of the succession of
such trustee hereunder to the holders of Notes at their addresses as they shall
appear on the Note register. If the Company fails to mail such notice within ten
(10) days

                                      -46-

<PAGE>

after acceptance of appointment by the successor trustee, the successor trustee
shall cause such notice to be mailed at the expense of the Company.

         SECTION 8.12 SUCCESSION BY MERGER, ETC. Any corporation into which the
Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation succeeding to all or substantially
all of the corporate trust business of the Trustee (including the administration
of the trust created by this Indenture), shall be the successor to the Trustee
hereunder without the execution or filing of any paper or any further act on the
part of any of the parties hereto, provided that in the case of any corporation
succeeding to all or substantially all of the corporate trust business of the
Trustee such corporation shall be qualified under the provisions of Section 8.8
and eligible under the provisions of Section 8.9.

         In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture, any of the Notes shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate
of authentication of any predecessor trustee or authenticating agent appointed
by such predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or any authenticating agent appointed by such successor
trustee may authenticate such Notes in the name of the successor trustee; and in
all such cases such certificates shall have the full force that is provided in
the Notes or in this Indenture; provided, however, that the right to adopt the
certificate of authentication of any predecessor Trustee or authenticate Notes
in the name of any predecessor Trustee shall apply only to its successor or
successors by merger, conversion or consolidation.

         SECTION 8.13 PREFERENTIAL COLLECTION OF CLAIMS. If and when the Trustee
shall be or become a creditor of the Company (or any other obligor upon the
Notes), 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 8.14 TRUSTEE'S APPLICATION FOR INSTRUCTIONS FROM THE COMPANY.
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 of the Notes or holders of
Senior Debt under this Indenture, including, without limitation, under Article
IV 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
three (3) 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.

                           CONCERNING THE NOTEHOLDERS

         SECTION 9.1 ACTION BY NOTEHOLDERS. Whenever in this Indenture it is
provided that the holders of a specified percentage in aggregate principal
amount of the Notes may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by Noteholders
in person or by agent or proxy appointed in writing, or (b) by the record of the
holders of Notes voting in favor thereof at any meeting of Noteholders duly
called and held in accordance with the provisions of Article X, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of Noteholders. Whenever the Company or the Trustee solicits the taking
of any action by the holders of the Notes, the Company or the Trustee may fix in
advance of such solicitation, a date as the record date for determining holders
entitled to take such action. The record date shall be not more than fifteen
(15) days prior to the date of commencement of solicitation of such action.

         SECTION 9.2 PROOF OF EXECUTION BY NOTEHOLDERS. Subject to the
provisions of Sections 8.1, 8.2 and 10.5, proof of the execution of any
instrument by a Noteholder or its agent or proxy shall be sufficient if made in
accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in such manner as shall be satisfactory to the Trustee. The
holding of Notes shall be proved by the registry of such Notes or by a
certificate of the Note registrar.

         The record of any Noteholders' meeting shall be proved in the manner
provided in Section 10.6.

         SECTION 9.3 WHO ARE DEEMED ABSOLUTE OWNERS. The Company, the Trustee,
any paying agent, any conversion agent and any Note registrar may deem the
person in whose name such Note shall be registered upon the Note register to be,
and may treat it as, the absolute owner of such Note (whether or not such Note
shall be overdue and notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving payment of or on account of the principal
of, premium, if any, and interest on such Note, for conversion of such Note and
for all other purposes; and neither the Company nor the Trustee nor any paying
agent nor any conversion agent nor any Note registrar shall be affected by any
notice to the contrary. All such payments so made to any holder for the time
being, or upon his order, shall be valid, and, to the extent of the sum or sums
so paid, effectual to satisfy and discharge the liability for monies payable
upon any such Note.

         SECTION 9.4 COMPANY-OWNED NOTES DISREGARDED. In determining whether the
holders of the requisite aggregate principal amount of Notes have concurred in
any direction, consent, waiver or other action under this Indenture, Notes which
are owned by the Company or any other obligor on the Notes or any Affiliate of
the Company or of any other obligor on the Notes shall be disregarded and deemed
not to be outstanding for the purpose of any such determination;

                                      -48-

<PAGE>

provided that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, consent, waiver or other action only
Notes which a Responsible Officer knows are so owned shall be so disregarded.
Notes so owned which have been pledged in good faith may be regarded as
outstanding for the purposes of this Section 9.4 if the pledgee shall establish
to the satisfaction of the Trustee the pledgee's right to vote such Notes and
that the pledgee is not the Company, any other obligor on the Notes or any
Affiliate of the Company or of any such other obligor. In the case of a dispute
as to such right, any decision by the Trustee taken upon the advice of counsel
shall be full protection to the Trustee. Upon request of the Trustee, the
Company shall furnish to the Trustee promptly an Officers' Certificate listing
and identifying all Notes, if any, known by the Company to be owned or held by
or for the account of any of the above described persons; and, subject to
Section 8.1, the Trustee shall be entitled to accept such Officers' Certificate
as conclusive evidence of the facts therein set forth and of the fact that all
Notes not listed therein are outstanding for the purpose of any such
determination.

         SECTION 9.5 REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND. At any time
prior to (but not after) the evidencing to the Trustee, as provided in Section
9.1, of the taking of any action by the holders of the percentage in aggregate
principal amount of the Notes specified in this Indenture in connection with
such action, any holder of a Note which is shown by the evidence to be included
in the Notes the holders of which have consented to such action may, by filing
written notice with the Trustee at its Corporate Trust Office and upon proof of
holding as provided in Section 9.2, revoke such action so far as concerns such
Note. Except as aforesaid, any such action taken by the holder of any Note shall
be conclusive and binding upon such holder and upon all future holders and
owners of such Note and of any Notes issued in exchange or substitution
therefor, irrespective of whether any notation in regard thereto is made upon
such Note or any Note issued in exchange or substitution therefor.

                                   ARTICLE X

                              NOTEHOLDERS' MEETINGS

every meeting of the Noteholders, setting forth the time and the place of such
meeting and in general terms the action proposed to be taken at such meeting and
the establishment of any record date pursuant to Section 9.1, shall be mailed to
holders of Notes at their addresses as they shall appear on the Note register.
Such notice shall also be mailed to the Company. Such notices shall be mailed
not less than twenty (20) nor more than ninety (90) days prior to the date fixed
for the meeting.

         Any meeting of Noteholders shall be valid without notice if the holders
of all Notes then outstanding are present in person or by proxy or if notice is
waived before or after the meeting by the holders of all Notes outstanding, and
if the Company and the Trustee are either present by duly authorized
representatives or have, before or after the meeting, waived notice.

         SECTION 10.3 CALL OF MEETINGS BY COMPANY OR NOTEHOLDERS. In case at any
time the Company, pursuant to a resolution of its Board of Directors, or the
holders of at least ten percent (10%) in aggregate principal amount of the Notes
then outstanding, shall have requested the Trustee to call a meeting of
Noteholders, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed the
notice of such meeting within twenty (20) days after receipt of such request,
then the Company or such Noteholders may determine the time and the place for
such meeting and may call such meeting to take any action authorized in Section
10.1, by mailing notice thereof as provided in Section 10.2.

         SECTION 10.4 QUALIFICATIONS FOR VOTING. To be entitled to vote at any
meeting of Noteholders a person shall (a) be a holder of one or more Notes on
the record date pertaining to such meeting, or (b) be a person appointed by an

date pertaining to such meeting. The only persons who shall be entitled to be
present or to speak at any meeting of Noteholders shall be the persons entitled
to vote at such meeting and their counsel and any representatives of the Trustee
and its counsel and any representatives of the Company and its counsel.

         SECTION 10.5 REGULATIONS. Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Noteholders, in regard to proof of the holding of
Notes and of the appointment of proxies, and in regard to the appointment and
duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters
concerning the conduct of the meeting as it shall think fit.

         The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Noteholders as provided in

                                      -50-

Section 10.3, in which case the Company or the Noteholders calling the
meeting, as the case may be, shall in like manner appoint a temporary chairman.
A permanent chairman and a permanent secretary of the meeting shall be elected
by vote of the holders of a majority in principal amount of the Notes
represented at the meeting and entitled to vote at the meeting.

         Subject to the provisions of Section 9.4, at any meeting each
Noteholder or proxyholder shall be entitled to one vote for each $1,000
principal amount of Notes held or represented by him; provided, however, that no
vote shall be cast or counted at any meeting in respect of any Note challenged
as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman of the meeting shall have no right to vote other than
by virtue of Notes held by him or instruments in writing as aforesaid duly
designating him as the proxy to vote on behalf of other Noteholders. Any meeting
of Noteholders duly called pursuant to the provisions of Section 10.2 or 10.3
may be adjourned from time to time by the holders of a majority of the aggregate
principal amount of Notes represented at the meeting, whether or not
constituting a quorum, and the meeting may be held as so adjourned without

the proceedings of each meeting of Noteholders shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the facts setting forth a
copy of the notice of the meeting and showing that said notice was mailed as
provided in Section 10.2 or Section 10.3. The record shall show the principal
amount of the Notes voting in favor of or against any resolution. The record

secretary of the meeting and one of the duplicates shall be delivered to the
Company and the other to the Trustee to be preserved by the Trustee, the latter
to have attached thereto the ballots voted at the meeting.

         Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

contained shall be deemed or construed to authorize or permit, by reason of any
call of a meeting of Noteholders or any rights expressly or impliedly conferred
hereunder to make such call, any hindrance or delay in the exercise of any right
or rights conferred upon or reserved to the Trustee or to the Noteholders under
any of the provisions of this Indenture or of the Notes.

         SECTION 11.1 SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF NOTEHOLDERS.
The Company, when authorized by the resolutions of the Board of Directors, and
the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto for one or more of the following purposes:

repurchase obligations of the Company pursuant to the requirements of Section
3.1(e);

                  (b) subject to Article IV, to convey, transfer, assign,

                  (c) to evidence the succession of another person to the
Company, or successive successions, and the assumption by the successor person

                  (d) to add to the covenants of the Company such further

occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions or conditions a default or an Event of
Default permitting the enforcement of all or any of the several remedies
provided in this Indenture as herein set forth; provided, however, that in
respect of any such additional covenant, restriction or condition 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;

                  (e) to provide for the issuance under this Indenture of Notes

questions arising under this Indenture that shall not materially adversely
affect the interests of the holders of the Notes;

                  (g) to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee with respect to the Notes; or

                                      -52-

<PAGE>

                  (h) to modify, eliminate or add to the provisions of this
Indenture to such extent as shall be necessary to effect the qualifications of
this Indenture under the Trust Indenture Act, or under any similar federal
statute hereafter enacted.

         Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any supplemental indenture, the Trustee
is hereby authorized to join with the Company in the execution of any such
supplemental indenture, to make any further appropriate agreements and
stipulations that may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder, but the Trustee shall not be
obligated to, but may in its discretion, enter into any supplemental indenture
that affects the Trustee's own rights, duties or immunities under this Indenture
or otherwise.

         Any supplemental indenture authorized by the provisions of this Section
11.1 may be executed by the Company and the Trustee without the consent of the
holders of any of the Notes at the time outstanding, notwithstanding any of the
provisions of Section 11.2.

         Notwithstanding any other provision of the Indenture or the Notes, the

         SECTION 11.2 SUPPLEMENTAL INDENTURE WITH CONSENT OF NOTEHOLDERS. With
the consent (evidenced as provided in Article IX) of the holders of not less
than a majority in aggregate principal amount of the Notes at the time
outstanding, the Company, when authorized by the resolutions of the Board of
Directors, and the Trustee may from time to time and at any time 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 any supplemental indenture or of modifying in any manner the
rights of the holders of the Notes; provided, however, that no such supplemental
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or
extend the time of payment of interest thereon, or reduce the principal amount
thereof or premium, if any, thereon, or reduce any amount payable on repurchase
thereof, or impair the right of any Noteholder to institute suit for the payment
thereof, or make the principal thereof or interest or premium, if any, thereon
payable in any coin or currency other than that provided in the Notes, or modify
the provisions of this Indenture with respect to the subordination of the Notes
in a manner materially adverse to the Noteholders, or change the obligation of
the Company to repurchase any Note upon the happening of a Fundamental Change in
a manner adverse to the holder of Notes, or impair the right to convert the
Notes into Common Stock subject to the terms set forth herein, including Section
15.6, in each case, without the consent of the holder of each Note so affected,
(ii) reduce the aforesaid percentage of Notes, the holders of which are required
to consent to (a) reduce the quorum or voting requirements under this Indenture
or (b) reduce the percentage of aggregate principal amount of outstanding Notes
required for consent to any modification of this Indenture, in each case,
without the consent of the holders of all Notes then outstanding or (iii) modify
any provisions of this Section or Section 7.7, except to increase any such
percentage or to provide that

                                      -53-

consent of the holders of each Note so affected.

         Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any such supplemental indenture, and upon
the filing with the Trustee of evidence of the consent of Noteholders as
aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

         It shall not be necessary for the consent of the Noteholders under this
Section 11.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

         SECTION 11.3 EFFECT OF SUPPLEMENTAL INDENTURE. Any supplemental
indenture executed pursuant to the provisions of this Article XI shall comply
with the Trust Indenture Act, as then in effect; provided that this Section 11.3
shall not require such supplemental indenture or the Trustee to be qualified
under the Trust Indenture Act prior to the time such qualification is in fact
required under the terms of the Trust Indenture Act or the Indenture has been
qualified under the Trust Indenture Act, nor shall it constitute any admission
or acknowledgment by any party to such supplemental indenture that any such
qualification is required prior to the time such qualification is in fact
required under the terms of the Trust Indenture Act or the Indenture has been
qualified under the Trust Indenture Act. Upon the execution of any supplemental
indenture pursuant to the provisions of this Article XI, this Indenture shall be
and be deemed to be modified and amended in accordance therewith and the
respective rights, limitation of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company and the holders of Notes shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

         SECTION 11.4 NOTATION ON NOTES. Notes authenticated and delivered after
the execution of any supplemental indenture pursuant to the provisions of this
Article XI may bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company or the Trustee shall
so determine, new Notes so modified as to conform, in the opinion of the Trustee
and the Board of Directors, to any modification of this Indenture contained in
any such supplemental indenture may, at the Company's expense, be prepared and
executed by the Company, authenticated by the Trustee (or an authenticating
agent duly appointed by the Trustee pursuant to Section 16.11) and delivered in
exchange for the Notes then outstanding, upon surrender of such Notes then
outstanding.

                CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

         SECTION 12.1 COMPANY MAY CONSOLIDATE ETC. ON CERTAIN TERMS. Subject to
the provisions of Section 12.2, nothing contained in this Indenture or in any of
the Notes shall prevent any consolidation or merger of the Company with or into
any other person or persons (whether or not affiliated with the Company), or
successive consolidations or mergers in which the Company or its successor or
successors shall be a party or parties, or shall prevent any sale, conveyance or
lease (or successive sales, conveyances or leases) of all or substantially all
of the property of the Company, to any other person (whether or not affiliated
with the Company), authorized to acquire and operate the same and that shall be
organized under the laws of the United States of America, any state thereof or
the District of Columbia; provided that upon any such consolidation, merger,
sale, conveyance or lease, the due and punctual payment of the principal of and
premium, if any, and interest (including Additional Interest, if any) on all of
the Notes, 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, shall be expressly assumed, by supplemental indenture
satisfactory in form to the Trustee, executed and delivered to the Trustee by
the person (if other than the Company) formed by such consolidation, or into
which the Company shall have been merged, or by the person that shall have
acquired or leased such property, and such supplemental indenture shall provide
for the applicable conversion rights set forth in Section 15.6.

         SECTION 12.2 SUCCESSOR CORPORATION TO BE SUBSTITUTED. In case of any
such consolidation, merger, sale, conveyance or lease and upon the assumption by
the successor person, by supplemental indenture, executed and delivered to the
Trustee and satisfactory in form to the Trustee, of the due and punctual payment
of the principal of and premium, if any, and interest on all of the Notes and
the due and punctual performance of all of the covenants and conditions of this
Indenture to be performed by the Company, 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. Such successor person thereupon may cause
to be signed, and may issue either in its own name or in the name of LSI Logic
Corporation any or all of the Notes issuable hereunder which 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, or cause to be authenticated and
delivered, any Notes which previously shall have been signed and delivered by
the officers of the Company to the Trustee for authentication, and any Notes
which such successor person thereafter shall cause to be signed and delivered to
the Trustee for that purpose. All the Notes

                                      -55-

<PAGE>

so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Notes theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Notes had been issued at the date
of the execution hereof. In the event of any such consolidation, merger, sale,
conveyance or lease, the person named as the "Company" in the first paragraph of
this Indenture or any successor which shall thereafter have become such in the
manner prescribed in this Article XII may be dissolved, wound up and liquidated
at any time thereafter and such person shall be released from its liabilities as
obligor and maker of the Notes and from its obligations under this Indenture.

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

         SECTION 12.3 OPINION OF COUNSEL TO BE GIVEN TRUSTEE. The Trustee shall
receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any such consolidation, merger, sale, conveyance or lease and any
such assumption complies with the provisions of this Article XII.

                                  ARTICLE XIII

                     SATISFACTION AND DISCHARGE OF INDENTURE

         SECTION 13.1 DISCHARGE OF INDENTURE. When (a) the Company shall deliver
to the Trustee for cancellation all Notes theretofore authenticated (other than
any Notes which have been destroyed, lost or stolen and in lieu of or in
substitution for which other Notes shall have been authenticated and delivered)
and not theretofore canceled, or (b) all the Notes not theretofore canceled or
delivered to the Trustee for cancellation shall have become due and payable, or
are by their terms to become due and payable within one year, and the Company
shall deposit with the Trustee, in trust, funds sufficient to pay at maturity of
all of the Notes (other than any Notes which shall have been mutilated,
destroyed, lost or stolen and in lieu of or in substitution for which other
Notes shall have been authenticated and delivered) not theretofore canceled or
delivered to the Trustee for cancellation, including principal and premium, if
any, and interest due or to become due to such date of maturity accompanied by a
verification report, as to the sufficiency of the deposited amount, from an
independent certified accountant or other financial professional satisfactory to
the Trustee, and if the Company shall also pay or cause to be paid all other
sums payable hereunder by the Company, then this Indenture shall cease to be of
further effect (except as to (i) remaining rights of registration of transfer,
substitution and exchange and conversion of Notes, (ii) rights hereunder of
Noteholders to receive payments of principal of and premium, if any, and
interest on, the Notes and the other rights, duties and obligations of
Noteholders, as beneficiaries hereof with respect to the amounts, if any, so
deposited with the Trustee and (iii) the rights, obligations and immunities of
the Trustee hereunder), and the Trustee, on written demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel as required by
Section 16.5 and at the cost and expense of the Company, shall execute proper
instruments acknowledging satisfaction of and

                                      -56-

<PAGE>

discharging this Indenture; the Company, however, hereby agreeing to reimburse
the Trustee for any costs or expenses thereafter reasonably and properly
incurred by the Trustee and to compensate the Trustee for any services
thereafter reasonably and properly rendered by the Trustee in connection with
this Indenture or the Notes.

         SECTION 13.2 DEPOSITED MONIES TO BE HELD IN TRUST BY TRUSTEE. Subject
to Section 13.4, all monies deposited with the Trustee pursuant to Section 13.1,
provided such deposit was not in violation of Article IV, shall be held in trust
for the sole benefit of the Noteholders and not to be subject to the
subordination provisions of Article IV, and such monies shall be applied by the
Trustee to the payment, either directly or through any paying agent (including
the Company if acting as its own paying agent), to the holders of the particular
Notes for the payment of which such monies have been deposited with the Trustee,
of all sums due and to become due thereon for principal and interest and
premium, if any.

         SECTION 13.3 PAYING AGENT TO REPAY MONIES HELD. Upon the satisfaction
and discharge of this Indenture, all monies then held by any paying agent of the
Notes (other than the Trustee) shall, upon written request of the Company, be
repaid to it or paid to the Trustee, and thereupon such paying agent shall be
released from all further liability with respect to such monies.

         SECTION 13.4 RETURN OF UNCLAIMED MONIES. Subject to the requirements of
applicable law, any monies deposited with or paid to the Trustee for payment of
the principal of, premium, if any, or interest on Notes and not applied but
remaining unclaimed by the holders of Notes for two years after the date upon
which the principal of, premium, if any, or interest on such Notes, as the case
may be, shall have become due and payable, shall be repaid to the Company by the
Trustee on demand and all liability of the Trustee shall thereupon cease with
respect to such monies; and the holder of any of the Notes shall thereafter look
only to the Company for any payment which such holder may be entitled to collect
unless an applicable abandoned property law designates another person.

         SECTION 13.5 REINSTATEMENT. If the Trustee or the paying agent is
unable to apply any money in accordance with Section 13.2 by reason of any order
or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 13.1 until such time as the Trustee or the paying
agent is permitted to apply all such money in accordance with Section 13.2;
provided, however, that if the Company makes any payment of interest on or
principal of any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the holders of such Notes to
receive such payment from the money held by the Trustee or paying agent.

                                  ARTICLE XIV

      IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

         SECTION 14.1 INDENTURE AND NOTES SOLELY CORPORATE OBLIGATIONS. No
recourse for the payment of the principal of or premium, if any, or interest on
any Note, or for any claim based thereon or otherwise in respect thereof, and no
recourse under or upon any obligation, covenant or agreement of the Company in
this Indenture or in any supplemental indenture or in any Note, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, employee, agent, officer, or director or subsidiary,
as such, past, present or future, of the Company or of any successor person,
either directly or through the Company or any successor person, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the Notes.

                                   ARTICLE XV

                               CONVERSION OF NOTES

         SECTION 15.1 RIGHT TO CONVERT. Subject to and upon compliance with the
provisions of this Indenture, including without limitation Article IV, the
holder of any Note shall have the right, at its option, at any time after
original issuance thereof through the close of business on the final maturity
date of the Notes (so long as such Note has not previously been repurchased by
the Company) to convert the principal amount of any such Note, or any portion of
such principal amount which is $1,000 or an integral multiple thereof. The Notes
will be convertible at the Conversion Rate, determined as hereinafter provided,
in effect at the time of conversion into fully paid and non-assessable shares of
Common Stock (as such shares shall then be constituted), by surrender of the
Note so to be converted in whole or in part in the manner provided, together
with any funds required by Section 15.2. A Note in respect of which a holder is
exercising its option to require repurchase upon a Fundamental Change pursuant
to Section 3.1 may be converted only if such holder withdraws its election to
exercise in accordance with Section 3.1. A holder of Notes is not entitled to
any rights of a holder of Common Stock until such holder has converted his Notes
to Common Stock, and only to the extent such Notes are deemed to have been
converted to Common Stock under this Article XV.

         SECTION 15.2 EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON STOCK
ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS. In order to exercise the
conversion privilege with respect to any Note in certificated form, the holder
of any such Note to be converted in whole or in part shall surrender such Note,
duly endorsed, at an office or agency maintained by the Company pursuant to
Section 5.2, accompanied by the funds, if any, required by the penultimate
paragraph of this Section 15.2, and shall give written notice of conversion in
the form provided on

                                      -58-

<PAGE>

the Notes (or such other notice which is acceptable to the Company) to the
office or agency that the holder elects to convert such Note or the portion
thereof specified in said notice. Such notice shall also state the name or names
(with address or addresses) in which the certificate or certificates for shares
of Common Stock which shall be issuable on such conversion shall be issued, and
shall be accompanied by transfer taxes, if required pursuant to Section 15.7.
Each such Note surrendered for conversion shall, unless the shares issuable on
conversion are to be issued in the same name as the registration of such Note,
be duly endorsed by, or be accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the holder or his duly authorized
attorney.

         In order to exercise the conversion privilege with respect to any
interest in a Note in global form, the holder must complete the appropriate
instruction form for conversion pursuant to the Depository's book-entry
conversion program, deliver by book-entry delivery an interest in such Note in
global form, furnish appropriate endorsements and transfer documents if required
by the Company or the Trustee or conversion agent, and pay the funds, if any,
required by this Section 15.2 and any transfer taxes if required pursuant to
Section 15.7.

         As promptly as practicable after satisfaction of the requirements for
conversion set forth above, subject to compliance with any restrictions on
transfer if shares issuable on conversion are to be issued in a name other than
that of the Noteholder (as if such transfer were a transfer of the Note or Notes
(or portion thereof) so converted), the Company shall issue and shall deliver to
such holder at the office or agency maintained by the Company for such purpose
pursuant to Section 5.2, a certificate or certificates for the number of full
shares of Common Stock issuable upon the conversion of such Note or portion
thereof in accordance with the provisions of this Article 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 15.3. In case any Note of a
denomination greater than $1,000 shall be surrendered for partial conversion,
and subject to Section 2.3, the Company shall execute and the Trustee shall
authenticate and deliver to the holder of the Note so surrendered, without
charge to him, a new Note or Notes in authorized denominations in an aggregate
principal amount equal to the unconverted portion of the surrendered Note.

         Each conversion shall be deemed to have been effected as to any such
Note (or portion thereof) on the date on which the requirements set forth above
in this Section 15.2 have been satisfied as to such Note (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
Note shall be surrendered.

         Any Note 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 close of business on the Business

                                      -59-

<PAGE>

Day next preceding the following interest payment date shall be accompanied by
payment, in New York Clearing House funds or other funds acceptable to the
Company, of an amount equal to the accrued but unpaid interest otherwise payable
on such interest payment date on the principal amount being converted. Except as
provided above in this Section 15.2, no payment or other adjustment shall be
made for unpaid interest accrued on any Note converted or for unpaid dividends
on any shares issued upon the conversion of such Note as provided in this
Article.

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

         SECTION 15.3 CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES. No fractional
shares of Common Stock or scrip representing fractional shares shall be issued
upon conversion of Notes. If more than one Note shall be surrendered for
conversion at one time by the same holder, the number of full shares which shall
be issuable upon conversion shall be computed on the basis of the aggregate
principal amount of the Notes (or specified portions thereof to the extent
permitted hereby) so surrendered. If any fractional share of stock would be
issuable upon the conversion of any Note or Notes, the Company shall make an
adjustment and payment therefor in cash at the current market price thereof to
the holder of Notes. The current market price of a share of Common Stock shall
be the Closing Price on the last Business Day immediately preceding the day on
which the Notes (or specified portions thereof) are deemed to have been
converted.

         SECTION 15.4 CONVERSION RATE. The conversion rate shall be as specified
in the form of Note (herein called the "Conversion Rate") attached as Exhibit A
hereto, subject to adjustment as provided in this Article XV.

         SECTION 15.5 ADJUSTMENT OF CONVERSION RATE. The Conversion Rate shall
be adjusted from time to time by the Company as follows:

                  (a) In case the Company shall hereafter pay a dividend or make
a distribution to all holders of the outstanding Common Stock in shares of
Common Stock, the Conversion Rate in effect at the opening of business on the
date next following the date fixed for the determination of stockholders
entitled to receive such dividend or other distribution shall be increased by
multiplying such Conversion Rate by a fraction the numerator of which shall be
the sum of the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination and the total number of shares
constituting such dividend or other distribution, and the denominator shall be
the number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination, such increase to become effective immediately
after the opening of business on the day following the date fixed for such
determination. The Company will not pay any dividend or make any distribution on
shares of Common Stock held in the treasury of the Company. If any dividend or
distribution of the type described in this Section 15.5(a) is declared but not
so paid or

                                      -60-

<PAGE>

made, the Conversion Rate shall again be adjusted to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared.

                  (b) In case the Company shall issue rights or warrants to all
holders of its outstanding shares of Common Stock entitling them (for a period
expiring within forty-five (45) days after the date fixed for determination of
stockholders entitled to receive such rights or warrants) to subscribe for or
purchase shares of Common Stock at a price per share less than the Current
Market Price (as defined below) on the date fixed for determination of
stockholders entitled to receive such rights or warrants, the Conversion Rate
shall be adjusted so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to the date fixed
for determination of stockholders entitled to receive such rights or warrants 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 determination of
stockholders entitled to receive such rights or warrants plus the total number
of additional shares of Common Stock offered for subscription or purchase and of
which the denominator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for determination of stockholders
entitled to receive such rights or warrants plus the number of shares that the
aggregate offering price of the total number of shares so offered would purchase
at such Current Market Price. Such adjustment shall be successively made
whenever any such rights or warrants are issued, and shall become effective
immediately after the opening of business on the day next following the date
fixed for determination of stockholders entitled to receive such rights or
warrants. To the extent that shares of Common Stock are not delivered after the
expiration of such rights or warrants, the Conversion Rate shall be readjusted
to the Conversion Rate which would then be in effect had the adjustments made
upon the issuance of such rights or warrants been made on the basis of delivery
of only the number of shares of Common Stock actually delivered. In the event
that such rights or warrants are not so issued, the Conversion Rate shall again
be adjusted to be the Conversion Rate which would then be in effect if such date
fixed for the determination of stockholders entitled to receive such rights or
warrants had not been fixed. In determining whether any rights or warrants
entitle the holders to subscribe for or purchase shares of Common Stock at less
than such Current Market Price, and in determining the aggregate offering price
of such shares of Common Stock, there shall be taken into account any
consideration received by the Company for such rights or warrants, the value of
such consideration, if other than cash, to be determined by the Board of
Directors (whose determination shall be conclusive and described in a resolution
of the Board of Directors).

                  (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 next following the day upon
which such subdivision becomes effective shall be proportionately increased, and
conversely, in case outstanding shares of Common Stock shall be combined into a
smaller number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day next 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 next following the day upon which such subdivision or
combination becomes effective.

                                      -61-

<PAGE>

                  (d) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock shares of any class of capital
stock of the Company (other than any dividends or distributions to which Section
15.5(a) applies) or evidences of its indebtedness or assets (including
securities, but excluding any rights or warrants referred to in Section 15.5(b),
and excluding any dividend or distribution (x) paid exclusively in cash or (y)
referred to in Section 15.5(a) (any of the foregoing hereinafter in this Section
15.5(d) called the "Securities")), then, in each such case (unless the Company
elects to reserve such Securities for distribution to the Noteholders upon the
conversion of the Notes so that any such holder converting Notes will receive
upon such conversion, in addition to the shares of Common Stock to which such
holder is entitled, the amount and kind of such Securities which such holder
would have received if such holder had converted its Notes into Common Stock
immediately prior to the Record Date (as defined in Section 15.5(h) for such
distribution of the Securities)), the Conversion Rate shall be increased so that
the same shall be equal to the rate determined by multiplying the Conversion
Rate in effect on the Record Date with respect to such distribution by a
fraction of which the numerator shall be the Current Market Price per share of
the Common Stock on the Record Date and of which the denominator shall be the
Current Market Price per share of the Common Stock on such Record Date less the
fair market value (as determined by the Board of Directors, whose determination
shall be conclusive, and described in a resolution of the Board of Directors) on
the Record Date of the portion of the Securities so distributed applicable to
one share of Common Stock, such increase to become effective immediately prior
to the opening of business on the day next following such Record Date; provided,
however, that in the event the then fair market value (as so determined) of the
portion of the Securities so distributed applicable to one share of Common Stock
is equal to or greater than the Current Market Price per share of the Common
Stock on such Record Date, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Noteholder shall have the right to receive
upon conversion the amount of Securities such holder would have received had
such holder converted each Note on such Record Date. In the event that such
dividend or distribution is not so paid or made, the Conversion Rate shall again
be adjusted to be the Conversion Rate which would then be in effect if such
dividend or distribution had not been declared. If the Board of Directors
determines the fair market value of any distribution for purposes of this
Section 15.5(d) by reference to the actual or when issued trading market for any
securities, it must in doing so consider the prices in such market over the same
period used in computing the Current Market Price of the Common Stock.
Notwithstanding the foregoing, if the Securities distributed by the Company to
all holders of its Common Stock consist of capital stock of, or similar equity
interests in, a Subsidiary or other business unit, the Conversion Rate shall be
increased so that the same shall be equal to the rate determined by multiplying
the Conversion Rate in effect on the Record Date with respect to such
distribution by a fraction:

                           (i) the numerator of which shall be the sum of (x)
the average Closing Price of one share of Common Stock over the ten consecutive
Trading Day period (the "Spinoff Valuation Period") commencing on and including
the fifth Trading Day after the date on which "ex-dividend trading" commences on
the Common Stock on the New York Stock Exchange or such other national or
regional exchange or market on which the Common Stock is then listed or quoted
and (y) the average Closing Price over the Spinoff Valuation Period of the
portion of the Securities so distributed applicable to one share of Common
Stock; and

                                      -62-

<PAGE>

                           (ii) the denominator of which shall be the average
Closing Price of one share of Common Stock over the Spinoff Valuation Period,

such adjustment to become effective immediately prior to the opening of business
on the day following such Record Date; provided, however, that the Company may
in lieu of the foregoing adjustment elect to reserve the pro rata portion of
such Securities so that each Holder of Securities shall have the right to
receive upon conversion the amount of such shares of capital stock or similar
equity interests of such Subsidiary or business unit that such Holder of
Securities would have received if such Holder of Securities had converted such
Securities on the Record Date with respect to such distribution.

         Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("Trigger Event"): (i) are deemed to be transferred with such shares of Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 15.5 (and no adjustment to the Conversion Rate under
this Section 15.5 will be required) until the occurrence of the earliest Trigger
Event, whereupon such rights and warrants shall be deemed to have been
distributed and an appropriate adjustment (if any is required) to the Conversion
Rate shall be made under this Section 15.5(d). If any such right or warrant,
including any such existing rights or warrants distributed prior to the date of
this Indenture, are subject to events, upon the occurrence of which such rights
or warrants become exercisable to purchase different securities, evidences of
indebtedness or other assets, then the date of the occurrence of any and each
such event shall be deemed to be the date of distribution and record date with
respect to new rights or warrants with such rights (and a termination or
expiration of the existing rights or warrants without exercise by any of the
holders thereof). In addition, in the event of any distribution (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of the
type described in the preceding sentence) with respect thereto that was counted
for purposes of calculating a distribution amount for which an adjustment to the
Conversion Rate under this Section 15.5 was made, (1) in the case of any such
rights or warrants which shall all have been redeemed or repurchased without
exercise by any holders thereof, the Conversion Rate shall be readjusted upon
such final redemption or repurchase to give effect to such distribution or
Trigger Event, as the case may be, as though it were a cash distribution, equal
to the per share redemption or repurchase price received by a holder or holders
of Common Stock with respect to such rights or warrants (assuming such holder
had retained such rights or warrants), made to all holders of Common Stock as of
the date of such redemption or repurchase, and (2) in the case of such rights or
warrants which shall have expired or been terminated without exercise by any
holders thereof, the Conversion Rate shall be readjusted as if such rights and
warrants had not been issued.

         No adjustment of the Conversion Rate shall be made pursuant to this
Section 15.5(d) in respect of rights or warrants distributed or deemed
distributed on any Trigger Event to the extent that

                                      -63-

<PAGE>

such rights or warrants are actually distributed to holders of Notes, or
reserved by the Company for distribution to holders of Notes upon conversion by
such holders of Notes to Common Stock.

         For purposes of this Section 15.5(d) and Sections 15.5(a) and (b), any
dividend or distribution to which this Section 15.5(d) is applicable that also
includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock (or both), shall be deemed instead to be (1) a
dividend or distribution of the evidences of indebtedness, assets or shares of
capital stock other than such shares of Common Stock or rights or warrants to
purchase shares of Common Stock (and any Conversion Rate increase required by
this Section 15.5(d) with respect to such dividend or distribution shall then be
made) immediately followed by (2) a dividend or distribution of such shares of
Common Stock or such rights or warrants (and any further Conversion Rate
increase required by Sections 15.5(a) and (b) with respect to such dividend or
distribution shall then be made), except (A) the Record Date of such dividend or
distribution shall be substituted as "the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution" and "the
date fixed for such determination" within the meaning of Sections 15.5(a) and
(b), respectively, and (B) 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 Section 15.5(a).

                  (e) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock cash (excluding (x) any quarterly
cash dividend on the Common Stock to the extent the aggregate cash dividend per
share of Common Stock in any fiscal quarter does not exceed the greater of (A)
the amount per share of Common Stock of the next preceding quarterly cash
dividend on the Common Stock to the extent that such preceding quarterly
dividend did not require any adjustment of the Conversion Rate pursuant to this
Section 15.5(e) (as adjusted to reflect subdivisions or combinations of the
Common Stock), and (B) 2.0% of the arithmetic average of the Closing Price
(determined as set forth in Section 15.5(h)) during the ten Trading Days (as
defined in Section 15.5(h)) immediately prior to the date of declaration of such
dividend, and (y) any dividend or distribution in connection with the
liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary), then, in such case, the Conversion Rate shall be increased so that
the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the close of business on the Record Date for such
dividend or distribution, as the case may be, by a fraction the numerator of
which shall be the Current Market Price of the Common Stock on such Record Date
and the denominator of which shall be the Current Market Price of the Common
Stock on the Record Date less the amount of cash so distributed (and not
excluded as provided above) applicable to one share of Common Stock, such
increase to be effective immediately prior to the opening of business on the day
next following the Record Date; provided, however, that in the event the portion
of the cash so distributed applicable to one share of Common Stock is equal to
or greater than the Current Market Price of the Common Stock on such Record
Date, in lieu of the foregoing adjustment, adequate provision shall be made so
that each Noteholder shall have the right to receive upon conversion the amount
of cash such holder would have received had such holder converted each Note on
such Record Date. In the event that such dividend or distribution is not so paid
or made, the Conversion Rate shall again be adjusted to be the Conversion Rate
which would

                                      -64-

<PAGE>

then be in effect if such dividend or distribution had not been declared. If any
adjustment is required to be made as set forth in this Section 15.5(e) as a
result of a distribution that is a quarterly dividend, such adjustment shall be
based upon the amount by which such distribution exceeds the amount of the
quarterly cash dividend permitted to be excluded pursuant hereto. If an
adjustment is required to be made as set forth in this Section 15.5(e) above as
a result of a distribution that is not a quarterly dividend, such adjustment
shall be based upon the full amount of the distribution.

                  (f) In case a tender or exchange offer made by the Company or
any Subsidiary for all or any portion of the Common Stock shall expire and such
tender or exchange offer (as amended upon the expiration thereof) shall require
the payment to stockholders of consideration per share of Common Stock having a
fair market value (as determined by the Board of Directors, whose determination
shall be conclusive and described in a resolution of the Board of Directors)
that as of the last time (the "Expiration Time") tenders or exchanges may be
made pursuant to such tender or exchange offer (as it may be amended) exceeds
the Current Market Price of the Common Stock on the Trading Day next succeeding
the Expiration Time, the Conversion Rate shall be increased so that the same
shall equal the rate determined by multiplying the Conversion Rate in effect
immediately prior to the Expiration Time by a fraction the numerator of which
shall be the sum of (x) 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 (y) the product of the number of shares of Common Stock
outstanding (less any Purchased Shares) at the Expiration Time and the Current
Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time, and the denominator of which shall be the number of shares of
Common Stock outstanding (including any tendered or exchanged shares) at the
Expiration Time multiplied by the Current Market Price of the Common Stock on
the Trading Day next succeeding the Expiration Time, such increase to become
effective immediately prior to the opening of business on the day next following
the Expiration Time. In the event that the Company is obligated to purchase
shares pursuant to any such tender or exchange offer, but the Company is
permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Conversion Rate shall again be adjusted to be
the Conversion Rate which would then be in effect if such tender or exchange
offer had not been made.

                  (g) In case of a tender or exchange offer made by a person
other than the Company or any Subsidiary for an amount which increases the
offeror's ownership of Common Stock to more than twenty-five percent (25%) of
the Common Stock outstanding and shall involve the payment by such person of
consideration per share of Common Stock having a fair market value (as
determined by the Board of Directors, whose determination shall be conclusive,
and described in a resolution of the Board of Directors) at the last time (the
"Offer Expiration Time") tenders or exchanges may be made pursuant to such
tender or exchange offer (as it shall have been amended) that exceeds the
Current Market Price of the Common Stock on the Trading Day next succeeding the
Offer Expiration Time, and in which, as of the Offer Expiration Time the Board
of Directors is not recommending rejection of the offer, the Conversion Rate
shall be increased so that the same shall

                                      -65-

<PAGE>

equal the rate determined by multiplying the Conversion Rate in effect
immediately prior to the Offer Expiration Time by a fraction of which the
numerator shall be the sum of (x) 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
Offer Expiration Time (the shares deemed so accepted, up to any such maximum,
being referred to as the "Accepted Purchased Shares") and (y) the product of the
number of shares of Common Stock outstanding (less any Accepted Purchased
Shares) on the Offer Expiration Time and the Current Market Price of the Common
Stock on the Trading Day next succeeding the Offer Expiration Time, and the
denominator of which shall be the number of shares of Common Stock outstanding
(including any tendered or exchanged shares) at the Offer Expiration Time
multiplied by the Current Market Price of the Common Stock on the Trading Day
next succeeding the Offer Expiration Time, such increase to become effective
immediately prior to the opening of business on the day next following the Offer
Expiration Time. In the event that such person is obligated to purchase shares
pursuant to any such tender or exchange offer, but such person is permanently
prevented by applicable law from effecting any such purchases or all such
purchases are rescinded, the Conversion Rate shall again be adjusted to be the
Conversion Rate which would then be in effect if such tender or exchange offer
had not been made. Notwithstanding the foregoing, the adjustment described in
this Section 15.5(g) shall not be made if, as of the Offer Expiration Time, the
offering documents with respect to such offer disclose a plan or intention to
cause the Company to engage in any transaction described in Article XII.

                  (h) For purposes of this Section 15.5, the following terms
shall have the meaning indicated:

                           (i) "Closing Price" with respect to any securities on
any day shall mean the closing sale price regular way on such day or, in case no
such sale takes place on such day, the average of the reported closing bid and
asked prices, regular way, in each case as quoted on the New York Stock Exchange
Composite Tape, or, if such security is not listed or admitted to trading on the
New York Stock Exchange Composite Tape, on the principal national security
exchange or quotation system on which such security is quoted or listed or
admitted to trading, or, if not quoted or listed or admitted to trading on any
national securities exchange or quotation system, the average of the closing bid
and asked prices of such security on the over-the-counter market on the day in
question as reported by the National Quotation Bureau Incorporated, or a similar
generally accepted reporting service, or if not so available, in such manner as
furnished by any New York Stock Exchange member firm selected from time to time
by the Board of Directors for that purpose, or a price determined in good faith
by the Board of Directors or, to the extent permitted by applicable law, a duly
authorized committee thereof, whose determination shall be conclusive.

                           (ii) "Current Market Price" shall mean 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
(1) if the "ex" date (as hereinafter defined) for any event (other than the
issuance or distribution or Fundamental Change requiring such computation) that

                                      -66-

<PAGE>

requires an adjustment to the Conversion Rate pursuant to Section 15.5(a), (b),
(c), (d), (e), (f) or (g) occurs during such ten consecutive Trading Days, the
Closing Price for each Trading Day prior to the "ex" date for such other event
shall be adjusted by dividing such Closing Price by the same fraction by which
the Conversion Rate is so required to be adjusted as a result of such other
event, (2) if the "ex" date for any event (other than the issuance, distribution
or Fundamental Change requiring such computation) that requires an adjustment to
the Conversion Rate pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g)
occurs on or after the "ex" date for the issuance or distribution requiring such
computation and prior to the day in question, the Closing Price for each Trading
Day on and after the "ex" date for such other event shall be adjusted by
dividing such Closing Price by the reciprocal of the fraction by which the
Conversion Price is so required to be adjusted as a result of such other event,
and (3) if the "ex" date for the issuance, distribution or Fundamental Change
requiring such computation is prior to the day in question, after taking into
account any adjustment required pursuant to clause (1) or (2) 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 (as
determined by the Board of Directors or, to the extent permitted by applicable
law, a duly authorized committee thereof in a manner consistent with any
determination of such value for purposes of Section 15.5(d), (f) or (g), whose
determination shall be conclusive and described in a resolution of the Board of
Directors or such duly authorized committee thereof, as the case may be) of the
evidences of indebtedness, shares of capital stock or assets being distributed
applicable to one share of Common Stock as of the close of business on the day
before such "ex" date. For purposes of any computation under Section 15.5(f) or
(g), the Current Market Price of the Common Stock on any date shall be deemed to
be the average of the daily Closing Prices per share of Common Stock for such
day and the next two succeeding Trading Days; provided, however, that if the
"ex" date for any event (other than the tender or exchange offer requiring such
computation) that requires an adjustment to the Conversion Rate pursuant to
Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs on or after the
Expiration Time or Offer Expiration Time, as the case may be, for the tender or
exchange offer requiring such computation and prior to the day in question, the
Closing Price for each Trading Day on and after the "ex" date for such other
event shall be adjusted by dividing 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. For purposes of this paragraph, the term "ex" date, (1)
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, (2) 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
(3) 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 Offer Expiration Time of such offer.

                           (iii) "fair market value" shall mean the amount which
a willing buyer would pay a willing seller in an arm's length transaction.

                                      -67-

<PAGE>

                           (iv) "Record Date" shall mean, with respect to any
dividend, distribution or other transaction or event in which the holders of
Common Stock have the right to receive any cash, securities or other property or
in which the Common Stock (or other applicable security) is exchanged for or
converted into any combination of cash, securities or other property, the date
fixed for determination of stockholders entitled to receive such cash,
securities or other property (whether such date is fixed by the Board of
Directors or by statute, contract or otherwise).

                           (v) "Trading Day" shall mean (x) if the applicable
security is listed or admitted for trading on the New York Stock Exchange or
another national security exchange, a day on which the New York Stock Exchange
or another national security exchange is open for business or (y) if the
applicable security is quoted on the Nasdaq National Market, a day on which
trades may be made on thereon or (z) if the applicable security is not so
listed, admitted for trading or quoted, any day other than a Saturday or Sunday
or a day on which banking institutions in the State of New York are authorized
or obligated by law or executive order to close.

                  (i) The Company may make such increases in the Conversion
Rate, in addition to those required by Sections 15.5 (a), (b), (c), (d), (e),
(f) or (g) as the Board of Directors considers to be advisable to avoid or
diminish any income tax to holders of Common Stock or rights to purchase Common
Stock resulting from any dividend or distribution of stock (or rights to acquire
stock) or from any event treated as such for income tax purposes.

         To the extent permitted by applicable law, the Company from time to
time may increase the Conversion Rate by any amount for any period of time if
the increase is irrevocable during the period and the Board of Directors shall
have made a determination that such increase would be in the best interests of
the Company, which determination shall be conclusive. Whenever the Conversion
Rate is increased pursuant to the preceding sentence, the Company shall mail to
holders of record of the Notes a notice stating the increased Conversion Rate
and the period during which it will be in effect.

                  (j) No adjustment in the Conversion Rate shall be required
unless such adjustment would require an increase or decrease of at least one
percent (1%) in such rate; provided, however, that any adjustments which by
reason of this Section 15.5(j) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Article XV shall be made by the Company to the nearest one-ten
thousandth (1/10,000) of a share. No adjustment need be made for rights to
purchase Common Stock pursuant to a Company plan for reinvestment of dividends
or interest. To the extent the Notes become convertible into cash, assets,
property or securities (other than capital stock of the Company), no adjustment
need be made thereafter as to the cash, assets, property or such securities.
Interest will not accrue on the cash.

                  (k) Whenever the Conversion Rate is adjusted as herein
provided or the Company reserves securities for distribution to holders of Notes
upon their conversion into Common Stock, the Company shall promptly file with
the Trustee and any conversion agent other than the Trustee an Officers'
Certificate setting forth the Conversion Rate after such adjustment and setting
forth a brief statement of the facts requiring such adjustment or, in the event
of a reservation by the Company, a brief statement of the relevant facts and a
valuation of the securities so reserved. Unless and until a

                                      -68-

<PAGE>

Responsible Officer of the Trustee has received such certificate, the Trustee
may assume that the Conversion Rate set forth in the form of the Note attached
hereto as Exhibit A or in the most recent notice it has received pursuant to
this Section 15.5 remains in effect and has not been, and is not required to be,
changed. Promptly after delivery of such certificate, the Company shall prepare
a notice of such adjustment of the Conversion Rate setting forth the adjusted
Conversion Rate (or a notice of the reservation of securities and a brief
description thereof, as the case may be) and the date on which each adjustment
or reservation becomes effective and shall mail such notice of such adjustment
of the Conversion Rate to the holder of each Note at his last address appearing
on the Note register provided for in Section 2.5 of this Indenture, within
twenty (20) days after execution thereof. Failure to deliver such notice shall
not affect the legality or validity of any such adjustment or reservation.

                  (l) In any case in which this Section 15.5 provides that an
adjustment shall become effective immediately after a record date for an event,
the Company may defer until the occurrence of such event (i) issuing to the
holder of any Note converted after such record date and before the occurrence of
such event the additional shares of Common Stock issuable upon such conversion
by reason of the adjustment required by such event over and above the Common
Stock issuable upon such conversion before giving effect to such adjustment and
(ii) paying to such holder any amount in cash in lieu of any fraction pursuant
to Section 15.3.

                  (m) For purposes of this Section 15.5, the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company but shall include shares issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. The Company
will not pay any dividend or make any distribution on shares of Common Stock
held in the treasury of the Company.

         SECTION 15.6 EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.
If any of the following events occur, namely (i) any reclassification or change
of the outstanding shares of Common Stock (other than a subdivision or
combination to which Section 15.5(c) applies), (ii) any consolidation, merger or
combination of the Company with another person as a result of which holders of
Common Stock shall be entitled to receive stock, securities or other property or
assets (including cash) with respect to or in exchange for such Common Stock, or
(iii) any sale or conveyance of all or substantially all of the properties and
assets of the Company to any other person as a result of which holders of Common
Stock shall be entitled to receive stock, securities or other property or assets
(including cash) with respect to or in exchange for such Common Stock, then the
Company or the successor or purchasing person, as the case may be, shall execute
with the Trustee a supplemental indenture (which shall comply with the Trust
Indenture Act as in force at the date of execution of such supplemental
indenture) providing that such Note shall be convertible into the kind and
amount of shares of stock and other securities or property or assets (including
cash) receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance by a holder of a number of shares of Common
Stock issuable upon conversion of such Notes (assuming, for such purposes, a
sufficient number of authorized shares of Common Stock available to convert all
such Notes) immediately prior to such reclassification, change, consolidation,

                                      -69-

<PAGE>

merger, combination, sale or conveyance assuming such holder of Common Stock did
not exercise his rights of election, if any, as to the kind or amount of
securities, cash or other property receivable upon such reclassification,
change, consolidation, merger, combination, sale or conveyance (provided that,
if the kind or amount of securities, cash or other property receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance
is not the same for each share of Common Stock in respect of which such rights
of election shall not have been exercised ("nonelecting share"), then for the
purposes of this Section 15.6 the kind and amount of securities, cash or other
property receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance for each non-electing share shall be deemed to
be the kind and amount so receivable per share by a plurality of the
non-electing shares). Such supplemental indenture shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article.

         The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes, at its address appearing on the
Note register provided for in Section 2.5 of this Indenture, within twenty (20)
days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

         The above provisions of this Section shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

         If this Section 15.6 applies to any event or occurrence, Section 15.5
shall not apply.

         SECTION 15.7 TAXES ON SHARES ISSUED. The issue of stock certificates on
conversions of Notes shall be made without charge to the converting Noteholder
for any tax in respect of the issue thereof. The Company shall not, however, be
required to pay any tax which 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 Note converted, and the Company shall not be required to issue or deliver
any such stock 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.

         SECTION 15.8 RESERVATION OF SHARES; SHARES TO BE FULLY PAID; COMPLIANCE
WITH GOVERNMENTAL REQUIREMENTS; LISTING OF COMMON STOCK. The Company shall
provide, free from preemptive rights, out of its authorized but unissued shares
or shares held in treasury, sufficient shares of Common Stock to provide for the
conversion of the Notes from time to time as such Notes are presented for
conversion.

         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 Notes, the Company will take all corporate
action which 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.

                                      -70-

<PAGE>

         The Company covenants that all shares of Common Stock which may be
issued upon conversion of Notes will upon issue be fully paid and non-assessable
by the Company and free from all taxes, liens and charges with respect to the
issue thereof.

         The Company covenants that if any shares of Common Stock to be provided
for the purpose of conversion of Notes 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 will in good
faith and as expeditiously as possible endeavor to secure such registration or
approval, as the case may be.

         The Company further covenants that if at any time the Common Stock
shall be listed on the New York Stock Exchange or any other national securities
exchange or automated quotation system the Company will, if permitted by the
rules of such exchange or automated quotation system, list and keep listed, so
long as the Common Stock shall be so listed on such exchange or automated
quotation system, all Common Stock issuable upon conversion of the Notes;
provided, however, that if rules of such exchange or automated quotation system
permit the Company to defer the listing of such Common Stock until the first
conversion of the Notes into Common Stock in accordance with the provisions of
this Indenture, the Company covenants to list such Common Stock issuable upon
conversion of the Notes in accordance with the requirements of such exchange or
automated quotation system at such time.

         SECTION 15.9 RESPONSIBILITY OF TRUSTEE. The Trustee and any other
conversion agent shall not at any time be under any duty or responsibility to
any holder of Notes to determine the Conversion Rate or whether any facts exist
which may require any adjustment of the Conversion Rate, or with respect to the
nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. The Trustee and any other
conversion agent shall not be accountable with respect to the validity or value
(or the kind or amount) of any shares of Common Stock, or of any securities or
property, which may at any time be issued or delivered upon the conversion of
any Note; and the Trustee and any other conversion agent make no representations
with respect thereto. Neither the Trustee nor any conversion agent shall be
responsible for any failure of the Company to issue, transfer or deliver any
shares of Common Stock or stock certificates or other securities or property or
cash upon the surrender of any Note for the purpose of conversion or to comply
with any of the duties, responsibilities or covenants of the Company contained
in this Article. Without limiting the generality of the foregoing, neither the
Trustee nor any conversion agent shall be under any responsibility to determine
the correctness of any provisions contained in any supplemental indenture
entered into pursuant to Section 15.6 relating either to the kind or amount of
shares of stock or securities or property (including cash) receivable by
Noteholders upon the conversion of their Notes after any event referred to in
such Section 15.6 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 8.1, may accept as conclusive evidence of
the correctness of any such provisions, and shall be protected in relying upon,
the Officers' Certificate (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect
thereto.

                                      -71-

<PAGE>

         SECTION 15.10 NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS. In case:

                  (a) the Company shall declare a dividend (or any other
distribution) on its Common Stock that would require an adjustment in the
Conversion Rate pursuant to Section 15.5; or

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

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

                  (d) of the voluntary or involuntary dissolution, liquidation
or winding up of the Company or any Significant Subsidiary;

         the Company shall cause to be filed with the Trustee and to be mailed
to each holder of Notes at his address appearing on the Note register provided
for in Section 2.5 of this Indenture, as promptly as possible but in any event
at least fifteen (15) days prior to the applicable date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution or rights or warrants, or, if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled
to such dividend, distribution or rights are to be determined, or (y) the date
on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up is expected to become effective or occur,
and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up. Unless and until a Responsible Officer
of the Trustee has received such notice, the Trustee shall not be deemed to have
knowledge of the facts and statements made therein.

         SECTION 15.11 RIGHTS ISSUED IN RESPECT OF COMMON STOCK ISSUED UPON
CONVERSION. Each share of Common Stock issued upon conversion of Notes pursuant
to this Article XV shall be entitled to receive the appropriate number of common
stock or preferred stock purchase rights, as the case may be (the "Rights"), if
any, that shares of Common Stock are entitled to receive and the certificates
representing the Common Stock issued upon such conversion shall bear such
legends, if any, in each case as may be provided by the terms of any shareholder
rights agreement adopted by the Company, as the same may be amended from time to
time (in each case, a "Rights Agreement"). Provided that such Rights Agreement
requires that each share of Common Stock issued upon conversion of Notes at any
time prior to the distribution of separate certificates representing the

                                      -72-

<PAGE>

Rights be entitled to receive such Rights, then, notwithstanding anything else
to the contrary in this Article XV there shall not be any adjustment to the
conversion privilege or Conversion Rate as a result of the issuance of Rights,
but an adjustment to the Conversion Rate shall be made pursuant to Section
15.5(d) (to the extent required thereby) upon the separation of the Rights from
the Common Stock.

                                  ARTICLE XVI

                            MISCELLANEOUS PROVISIONS

         SECTION 16.1 PROVISIONS BINDING ON COMPANY'S SUCCESSORS. All the
covenants, stipulations, promises and agreements by the Company contained in
this Indenture shall bind its successors and assigns whether so expressed or
not.

         SECTION 16.2 OFFICIAL ACTS BY SUCCESSOR CORPORATION. Any act or
proceeding by any provision of this Indenture authorized or required to be done
or performed by any board, committee or officer of the Company shall and may be
done and performed with like force and effect by the like board, committee or
officer of any person that shall at the time be the lawful sole successor of the
Company.

         SECTION 16.3 ADDRESSES FOR NOTICES, ETC. Any notice or demand which by
any provision of this Indenture is required or permitted to be given or served

the original issuance thereof and transfers and exchanges of Notes hereunder,
including under Sections 2.4, 2.5, 2.6, 2.7, and 3.1, as fully to all intents
and purposes as though the authenticating agent had been expressly authorized by
this Indenture and those Sections to authenticate and deliver Notes. For all
purposes of this Indenture, the authentication and delivery of Notes by the
authenticating agent shall be deemed to be authentication and delivery of such
Notes "by the Trustee" and a certificate of authentication executed on behalf of

corporation.

         Any authenticating agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time terminate the agency of any authenticating agent by giving written notice
of termination to such authenticating agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any authenticating agent shall cease to be eligible under this Section, the
Trustee shall either promptly appoint a successor authenticating agent or itself
assume the duties and obligations of the former authenticating agent under this
Indenture, and upon such appointment of a successor

                                      -75-

<PAGE>

authenticating agent, if made, shall give written notice of such appointment of
a successor authenticating agent to the Company and shall mail notice of such
appointment of a successor authenticating agent to all holders of Notes as the
names and addresses of such holders appear on the Note register.

         The Trustee agrees to pay to the authenticating agent from time to time
reasonable compensation for its services (to the extent pre-approved by the
Company in writing), and the Trustee shall be entitled to be reimbursed by the
Company for such pre-approved payments, subject to Section 8.6.

         The provisions of Sections 8.2, 8.3, 8.4, 9.3 and this Section 16.11

Indenture declared and provided, upon the terms and conditions hereinabove set
forth.

                              LSI LOGIC CORPORATION

                    4% CONVERTIBLE SUBORDINATED NOTE DUE 2010

         This Note is one of a duly authorized issue of Notes of the Company,
designated as its 4% Convertible Subordinated Notes due 2010 (herein called the
"Notes"), limited to the aggregate principal amount of $350,000,000
($402,500,000 if the Purchaser exercises in full its option to purchase
additional Notes) issued and to be issued under and pursuant to an indenture
dated as of May 16, 2003 (herein called the "Indenture"), between the Company
and U.S. Bank National Association, as trustee (herein called the "Trustee"), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the holders of the Notes.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest (including Additional Interest, if any) on all Notes may be declared,
and upon said declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, evidenced as in
the Indenture provided, to execute supplemental indentures adding any provisions
to or changing in any manner or eliminating any of the provisions of the
Indenture or of any supplemental indenture or modifying in any manner the rights
of the holders of the Notes; provided, however, that no such supplemental
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or
extend the time of payment of interest thereon, or reduce the principal amount
thereof or premium, if any, thereon, or reduce any amount payable on repurchase
thereof, or impair the right of any Noteholder to institute suit for the payment
thereof, or make the principal thereof or interest or premium, if any, thereon
payable in any coin or currency other than that provided in the Note, or modify
the provisions of the Indenture with respect to the subordination of the Notes
in a manner adverse to the Noteholders in any material respect, or change the
obligation of the Company to repurchase any Note upon the happening of a
Fundamental Change in a manner adverse to the holder of the Notes, or impair the
right to convert the Notes into Common Stock subject to the terms set forth in
the Indenture, including Section 15.6 thereof, without the consent of the holder
of each Note so affected or (ii) reduce the aforesaid percentage of Notes, the
holders of which are required to consent to any such supplemental indenture,
without the consent of the holders of all Notes then outstanding. It is also
provided in the Indenture that, prior to any declaration accelerating the
maturity of the Notes, the holders of a majority in aggregate principal amount
of the Notes at the time outstanding may on behalf of the holders of all of the
Notes waive any past default or Event of Default under the Indenture and its
consequences except a default in the payment of interest (including Additional
Interest, if any) or any premium on or the principal of any of the Notes, a
default in the payment of repurchase price pursuant to Article III or a failure
by the Company to

<PAGE>

convert any Notes into Common Stock of the Company. Any such consent or waiver
by the holder of this Note (unless revoked as provided in the Indenture) shall
be conclusive and binding upon such holder and upon all future holders and
owners of this Note and any Notes which may be issued in exchange or substitute
hereof, irrespective of whether or not any notation thereof is made upon this
Note or such other Notes.

         The indebtedness evidenced by the Notes is, to the extent and in the
manner provided in the Indenture, expressly subordinate and subject in right of
payment to the prior payment in full of all Senior Debt of the Company, as
defined in the Indenture, whether outstanding at the date of the Indenture or
thereafter incurred, and this Note is issued subject to the provisions of the
Indenture with respect to such subordination. Each holder of this Note, by
accepting the same, agrees to and shall be bound by such provisions and
authorizes the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination so provided and appoints the Trustee
his attorney-in-fact for such purpose.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium, if any, and
interest (including Additional Interest, if any) on this Note at the place, at
the respective times, at the rate and in the coin or currency herein prescribed.

         Interest on the Notes shall be computed on the basis of a 360-day year
of twelve 30-day months.

         The Notes are issuable in registered form without coupons in
denominations of $1,000 and any integral multiple of $1,000. At the office or
agency of the Company referred to on the face hereof, and in the manner and
subject to the limitations provided in the Indenture, without payment of any
service charge but with payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration or
exchange of Notes, Notes may be exchanged for a like aggregate principal amount
of Notes of other authorized denominations.

         The Notes will not be redeemable at the option of the Company prior to
the final maturity date of the Notes.

         The Notes are not subject to redemption through the operation of any
sinking fund.

         If a Fundamental Change (as defined in the Indenture) occurs at any
time prior to the final maturity date of the Notes, the Notes will be
repurchasable on the 30th day after notice thereof at the option of the holder.
Such repayment shall be made at a price equal to 100% of the principal amount to
be repurchased. The Company shall also pay accrued but unpaid interest, if any
(including Additional Interest, if any) on such Notes to, but excluding, the
Repurchase Date; provided that if such Repurchase Date is May 15 or November 15,
then the interest payable on such date shall be paid to the holder of record of
the Note on the next preceding May 1 or November 1. The Company shall mail to
all holders of record of the Notes a notice of the occurrence of a Fundamental
Change and of the repurchase right arising as a result thereof on or before the
10th day after the occurrence of

<PAGE>

such Fundamental Change. For a Note to be so repurchased at the option of the
holder, the Company must receive at the office or agency of the Company
maintained for that purpose in accordance with the terms of the Indenture, such
Note with the form entitled "Option to Elect Repayment Upon a Fundamental
Change" on the reverse thereof duly completed, together with such Notes duly
endorsed for transfer, on or before the 30th day after the date of such notice
(or if such 30th day is not a Business Day, the immediately preceding Business
Day).

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after the date of original issuance hereof
through the close of business on the final maturity date of this Note, so long
as such Note has not previously been repurchased by the Company, to convert the
principal hereof or any portion of such principal which is $1,000 or an integral
multiple thereof into that number of shares of the Company's Common Stock, as
said shares shall be constituted at the date of conversion, at an initial
Conversion Rate of 74.5156 shares of Common Stock per $1,000 principal amount of
Notes, as adjusted from time to time as provided in the Indenture, upon
surrender of this Note, together with a conversion notice as provided in the
Indenture, to the Company at the office or agency of the Company maintained for
that purpose in accordance with the terms of the Indenture, or at the option of
such holder, the Corporate Trust Office, and, unless the shares issuable on
conversion are to be issued in the same name as this Note, duly endorsed by, or
accompanied by instruments of transfer in form satisfactory to the Company duly
executed by, the holder or by his duly authorized attorney. No adjustment in
respect of interest or dividends will be made upon any conversion; provided,
however, that if this Note shall be surrendered for conversion during the period
from the close of business on any record date for the payment of interest to the
close of business on the Business Day next preceding the interest payment date,
this Note must be accompanied by an amount, in New York Clearing House funds or
other funds acceptable to the Company, equal to the interest payable on such
interest payment date on the principal amount being converted. No fractional
shares will be issued upon any conversion, but an adjustment in cash will be
made, as provided in the Indenture, in respect of any fraction of a share which
would otherwise be issuable upon the surrender of any Note or Notes for
conversion.

         Upon due presentment for registration of transfer of this Note at the
office or agency of the Company maintained for that purpose in accordance with
the terms of the Indenture, or at the option of the holder of this Note, at the
Corporate Trust Office, a new Note or Notes of authorized denominations for an
equal aggregate principal amount will be issued to the transferee in exchange
thereof; subject to the limitations provided in the Indenture, without charge
except for any tax or other governmental charge imposed in connection therewith.

         The Company, the Trustee, any authenticating agent, any paying agent,
any conversion agent and any Note registrar may deem and treat the registered
holder hereof as the absolute owner of this Note (whether or not this Note shall
be overdue and notwithstanding any notation of ownership or other writing hereon
made by anyone other than the Company or any Note registrar), for the purpose of
receiving payment hereof, or on account hereof, for the conversion hereof and
for all other purposes, and neither the Company nor the Trustee nor any other
authenticating agent nor any paying agent nor any other conversion agent nor any
Note registrar shall be affected by any notice to the

<PAGE>

contrary. All payments made to or upon the order of such registered holder
shall, to the extent of the sum or sums paid, satisfy and discharge liability
for monies payable on this Note.

         No recourse for the payment of the principal of or any premium or
interest on this Note, or for any claim based hereon or otherwise in respect
hereof; and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Note, or because of the creation of any indebtedness represented thereby, shall
be had against any incorporator, stockholder, employee, agent, officer or
director or subsidiary, as such, past, present or future, of the Company or of
any successor corporation, either directly or through the Company or any
successor corporation, whether by virtue of any constitution, statute or rule of
law or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released.

         This Note shall be deemed to be a contract made under the laws of New
York, and for all purposes shall be construed in accordance with the laws of New
York.

         The holders of this Note are entitled to the benefits of a Registration
Rights Agreement, dated as of May 16, 2003, between the Company and the
Purchaser.

         Terms used in this Note and defined in the Indenture are used herein as
therein defined.

Attn: Corporate Trust Services

Ladies/Gentlemen:

         We are delivering this letter in connection with an offering by LSI
Logic Corporation of 4% Convertible Subordinated Notes due 2010 (the "Notes),
which are convertible into shares of Common Stock, $.01 par value (the "Common
Stock"), all as described in the Offering Memorandum (the "Offering Memorandum")
relating to the offering.

         We hereby confirm that:

         1.       we are an "accredited investor" within the meaning of Rule
501(a)(1), (2) or (3) under the Securities Act of 1933, as amended (the
"Securities Act"), or an entity in which all of the equity owners are accredited
investors within the meaning of Rule 501(a)(1), (2) or (3) under the Securities
Act (an "Institutional Accredited Investor");

         2.       (A) any purchase of Notes by us will be for our own account or
for the account of one or more other Institutional Accredited Investors or as
fiduciary for the account of one or more trusts, each of which is an "accredited
investor" within the meaning of Rule 501(a)(7) under the Securities Act and for
each of which we exercise sole investment discretion or (B) we are a "bank,"
within the meaning of Section 3(a)(2) of the Securities Act, or a "savings and
loan association" or other institution described in Section 3(a)(5)(A) of the
Securities Act that is acquiring Notes as fiduciary for the account of one or
more institutions for which we exercise sole investment discretion;

         3.       in the event that we purchase any Notes, we will acquire Notes
having a minimum principal amount of not less than $200,000 for our own account
or for any separate account for which we are acting;

         4.       we have such knowledge and experience in financial and
business matters that we are capable of evaluating the merits and risks of
purchasing Notes;

         5.       we are not acquiring Notes with a view to distribution thereof
or with any present intention of offering or selling Notes or the Common Stock
issuable upon conversion thereof, except as permitted below; provided that the
disposition of our property and property of any accounts for which we are acting
as fiduciary shall remain at all times within our control; and

                                      B-1

<PAGE>

         6.       we have received a copy of the Offering Memorandum and
acknowledge that we have had access to such financial and other information, and
have been afforded the opportunity to ask such questions of representatives of
the Company and receive answers thereto, as we deem necessary in connection with
our decision to purchase Notes.

         We understand that the Notes are being offered in a transaction not
involving any public offering within the United States within the meaning of the
Securities Act and that the Notes and the Common Stock issuable upon conversion
thereof have not been registered under the Securities Act, and we agree, on our
own behalf and on behalf of each account for which we acquire any Notes, that if
in the future we decide to resell or otherwise transfer such Notes or the Common
Stock issuable upon conversion thereof, such Notes or Common Stock may be resold
or otherwise transferred only (i) to the Company or any subsidiary thereof, (ii)
to a person who is a "qualified institutional buyer" (as defined in Rule 144A
under the Securities Act) in a transaction meeting the requirements of Rule
144A, (iii) to an Institutional Accredited Investor that, prior to such
transfer, furnishes to the Trustee for the Notes (or in the case of Common
Stock, the transfer agent therefor) a signed letter containing certain
representations and agreements relating to the restrictions on transfer of such
securities (the form of which letter can be obtained from the Trustee or
transfer agent, as the case may be), (iv) pursuant to the exemption from
registration provided by Rule 144 under the Securities Act (if applicable), (v)
pursuant to and in compliance with Regulation S under the Securities Act, or
(vi) pursuant to a registration statement which has been declared effective
under the Securities Act (and which continues to be effective at the time of
such transfer), and in each case, in accordance with any applicable securities
laws of any State of the United States or any other applicable jurisdiction and
in accordance with the legends set forth on the Notes or the Common Stock
issuable upon conversion thereof. We further agree to provide any person
purchasing any of the Notes or the Common Stock issuable upon conversion thereof
(other than pursuant to clause (vi) above) from us a notice advising such
purchaser that resales of such securities are restricted as stated herein. We
understand that the Trustee or transfer agent for the Notes and the Common Stock
will not be required to accept for registration of transfer any Notes or Common
Stock issued upon conversion of the Notes except upon presentation of evidence
satisfactory to the Company that the foregoing restrictions on transfer have
been complied with. We further understand that certificates representing any
Notes (or any Note in global form) and any Common Stock issued upon conversion
of the Notes (other than pursuant to clause (vi) above) will bear a legend
reflecting the substance of this paragraph.

         We acknowledge that the Company, others and you will rely upon our
confirmations, acknowledgments and agreements set forth herein, and we agree to
notify you promptly in writing if any of our representations or warranties
herein ceases to be accurate and complete.
