         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 Company to the Trustee of the proposed payment

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,

of the Company, although at the date of the execution of this Indenture any such
person was not such an officer.

         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.

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

                  No service charge shall be charged to the Noteholder for any
         exchange or registration of transfer of Notes, but the Company may
         require payment of a sum sufficient to cover any tax, assessments or
         other governmental charges that may be imposed in connection therewith.

                  None of the Company, the Trustee, the Note registrar or any
         co-registrar shall be required to exchange or register a transfer of
         (a) any Notes for a period of fifteen (15) days next preceding any
         selection of Notes to be redeemed or (b) any Notes called for
         redemption or, if a portion of any Note is selected or called for
         redemption, such portion thereof selected or called for redemption or
         (c) any Notes surrendered for conversion or, if a portion of any Note
         is surrendered for conversion, such portion thereof surrendered for
         conversion or (d) any Notes, or a portion of any Note, surrendered for
         repurchase (and not withdrawn) in connection with a Repurchase Event.

                  All Notes issued upon any transfer or exchange of Notes in
         accordance with this Indenture 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.

                  (b) So long as the Notes are eligible for book-entry
         settlement with the Depositary, unless otherwise required by law, all
         Notes issued to QIBs pursuant to Rule 144A of the Securities Act to be
         traded on The Portal Market shall be represented by a Note in global
         form (the "Global Note") registered in the name of the Depositary or
         the nominee of the Depositary. The transfer and exchange of beneficial
         interests in the Global Note, which does not involve the issuance of a
         definitive Note, shall be effected through the Depositary (but not the
         Trustee or the Custodian) in accordance with this Indenture (including
         the restrictions on transfer set forth herein) and the procedures of
         the Depositary therefor.

                  Notes resold to persons who are not QIBs will be issued in
         definitive registered form and may not be represented by the Global
         Note. In addition, at any time at the request of a QIB that is a
         beneficial holder of an interest in the Global Note, such beneficial
         holder shall be entitled to obtain a definitive Note upon written
         request to the Trustee and the Custodian in accordance with the
         standing instructions and procedures existing between the Depositary
         and the Custodian for the issuance thereof. Upon receipt of any such
         request, the Trustee or the Custodian, at the direction of the Trustee,
         will cause, in accordance with the standing instructions and procedures
         existing between the Depositary and the Custodian, the aggregate
         principal amount of the Global Note to be reduced by the principal
         amount of the definitive Note issued upon such request to such
         beneficial holder and, following such reduction, the Company will
         execute and the Trustee will authenticate and deliver to such
         beneficial holder (or its nominee) a definitive Note or Notes in the
         appropriate aggregate principal amount in the name of such beneficial
         holder (or its nominee) and bearing such restrictive legends as may be
         required by this Indenture.

                  Any transfer of a beneficial interest in the Global Note which
         cannot be effected through book-entry settlement must be effected by
         the delivery to the transferee (or its nominee) of a definitive Note or
         Notes registered in the name of the transferee (or its nominee) on the
         books maintained by the Trustee in accordance with the transfer
         restrictions set forth herein. With respect to any such transfer, the
         Trustee or the Custodian, at the direction of the Trustee, will cause,
         in accordance with the standing instructions and procedures existing
         between the Depositary and the Custodian, the aggregate principal
         amount of the Global Note to be reduced by the principal amount of the
         beneficial interest in the Global Note being transferred and, following
         such reduction, the Company will execute and the Trustee will
         authenticate and deliver to the transferee (or such transferee's
         nominee, as the case may be), a Note or Notes in the appropriate
         aggregate principal amount in the name of such transferee (or its
         nominee) and bearing such restrictive legends as may be required by
         this Indenture.

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


                                      -13-

<PAGE>



         definitive Note or Notes being so transferred, together with a
         certification from the transferor that the transferee is a QIB (or
         other evidence satisfactory to the Trustee), the Trustee shall make or
         direct the Custodian to make, an endorsement on the Global Note to
         reflect an increase in the aggregate principal amount of the Notes
         represented by the Global Note by the principal amount of the Note
         being transferred to the QIB, the Trustee shall cancel such definitive
         Note or Notes and cause, or direct the Custodian to cause, in
         accordance with the standing instructions and procedures existing
         between the Depositary and the Custodian, the aggregate principal
         amount of Notes represented by the 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 the Global Note until such
         definitive Note is freely tradable in accordance with Rule 144(k);
         provided further that the Trustee shall authenticate and deliver Notes
         in definitive form upon any transfer of a beneficial interest in the
         Global Note to the Company or any Affiliate of the Company.

                  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 designated for issuance 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 either of the legends set forth in this Section 2.5(d)
         (together with any Common Stock issued upon conversion of the Notes and
         required to bear either of the legends 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
         one of the legends set forth below), unless such restrictions on
         transfer shall be waived by written consent of the Company, and the
         holder of each such Restricted Security, by such holder's acceptance
         thereof, agrees to be bound by all such restrictions on transfer. As
         used in Sections 2.5(d) and 2.5(e), the term "transfer" encompasses any
         sale, pledge, transfer or other disposition whatsoever of any
         Restricted Security.

                  Until two (2) years after the original issuance date of any
         Note, 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 Notes have been
         transferred pursuant to a registration statement that has been declared
         effective under the Securities Act (and

                  CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE

                  TRANSFER AND SUBMIT THIS CERTIFICATE TO THE FIRST NATIONAL

                  CHICAGO, AS TRUSTEE, SUCH CERTIFICATIONS, LEGAL OPINIONS OR
                  OTHER INFORMATION AS THE COMPANY MAY REASONABLY REQUIRE TO

                  EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
                  REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND
                  WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE NOTE
                  EVIDENCED HEREBY PURSUANT TO CLAUSE 2(D) OR 2(E) ABOVE OR THE
                  EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE NOTE
                  EVIDENCED HEREBY.

         Notwithstanding the foregoing dispositions of this Section 2.5(d), any
certificate evidencing a Note that has been transferred to an Affiliate of the
Company within two years after the original issuance date of the Note, as
evidenced by a check in the appropriate box on the Assignment effecting such
transfer or the representation letter delivered in respect thereof, for so long
as such Note is held by such Affiliate, shall bear a legend in substantially the
following form (unless such Notes have been transferred 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), pursuant to
the exemption from registration provided by Rule 144 under the Securities Act,
or unless otherwise agreed by the Company (with written notice thereof to the
Trustee):

         THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY STATE
         SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS
         SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE
         HOLDER (1) AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THE
         NOTE EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF
         SUCH NOTE EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B)
         PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER
         THE SECURITIES ACT (IF AVAILABLE), OR (C) 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
         (2) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE NOTE
         EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO
         CLAUSE 1(C) ABOVE) A NOTICE


                                      -16-

<PAGE>



         SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY
         TRANSFER OF THE NOTE EVIDENCED HEREBY (OTHER THAN A TRANSFER PURSUANT
         TO CLAUSE 1(C) ABOVE), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET
         FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND
         SUBMIT THIS CERTIFICATE TO THE FIRST NATIONAL BANK OF CHICAGO, AS
         TRUSTEE. IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 1(B) ABOVE, THE
         HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE FIRST NATIONAL BANK
         OF CHICAGO, AS TRUSTEE, SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
         INFORMATION AS THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH
         TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
         TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT.

                  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 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 this Section 2.5(d)), the Global Note
         may not be transferred as a whole or in part except by the Depositary
         to a nominee of the Depositary or by a nominee of the Depositary to the
         Depositary or another nominee of the Depositary or by the Depositary or
         any such nominee to a successor Depositary or a nominee of such
         successor Depositary.

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

                  If at any time the Depositary for the 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 for the Global Note 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 definitive form, in
         an aggregate principal amount equal to the principal amount of the
         Global Note, in exchange for the Global Note, and upon delivery of the
         Global Note to the Trustee the Global Note shall be canceled.

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

                  Definitive Notes issued in exchange for all or a part of the
         Global Note pursuant to this Section 2.5(d) 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 definitive Notes to the persons in whose
         names such definitive Notes are so registered.

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

                  (e) Until two (2) years after the original issuance date of
         any Note, any stock certificate representing Common Stock issued upon
         conversion of such Note shall bear a legend in substantially the
         following form (unless such Common Stock has been sold pursuant to the
         exemption from registration provided by Rule 144 under the Securities
         Act or pursuant to a registration statement that has been declared
         effective under the Securities Act, and which continues to be effective
         at the time of such transfer, or such Common Stock has been issued upon
         conversion 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 with written
         notice thereof to the Trustee and any transfer agent for the Common
         Stock):

                  THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN

         under the Securities Act or pursuant to a registration statement that
         has been declared effective under the Securities Act, and which

                  TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
                  REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT

                  THIS LEGEND.

                  Any such Common Stock as to which such restrictions on
         transfer shall have expired in accordance with their terms may, upon
         surrender of the certificates representing such shares of Common Stock
         for exchange in accordance with the procedures of the transfer agent
         for the Common Stock, be exchanged for a new certificate or
         certificates for a like aggregate number of shares of Common Stock,
         which shall not bear the restrictive legend required by this Section
         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 that results in such Notes or Common Stock, as the
         case may be, no longer being "restricted securities" (as defined under
         Rule 144).

                  (g) Notwithstanding any provision of Section 2.5 to the
         contrary, in the event Rule 144(k) as promulgated under the Securities
         Act (or any successor rule) is amended to change the two-year period
         under Rule 144(k) (or the corresponding period under any successor
         rule), from and after receipt by the Trustee of the Officers'
         Certificate and Opinion of Counsel provided for in this Section 2.5(g),
         (i) each reference in Section 2.5(d) to "two (2) years" and in the
         restrictive legends set forth in such paragraph to "TWO YEARS" shall be
         deemed for all purposes hereof to be references to such changed period,
         (ii) each reference in Section 2.5(e) to "two (2) years" and in the
         restrictive legends set forth in such paragraph to "TWO YEARS" shall be
         deemed for all purposes hereof to be references to such changed period
         and (iii) all corresponding references in the Notes and the restrictive
         legends thereon shall be deemed for all purposes hereof to be
         references to such changed period, provided that such changes shall not
         become effective if they are otherwise prohibited by, or would
         otherwise cause a violation of, the then-applicable federal securities
         laws. As soon as practicable after the Company has knowledge of the
         effectiveness of any such amendment to change the two-year period under
         Rule 144(k) (or the corresponding period under any successor rule),
         unless such changes would otherwise be prohibited by, or would 
         otherwise cause a 

                                      -21-

<PAGE>

         violation of, the then-applicable securities law, the Company shall
         provide to the Trustee an Officers' Certificate and Opinion of Counsel
         informing the Trustee of the effectiveness of such amendment and the
         effectiveness of the foregoing changes to Sections 2.5(d) and 2.5(e)
         and the Notes. The provisions of this Section 2.5(g) will not be
         effective until such time as the Opinion of Counsel and Officers'
         Certificate have been received by the Trustee hereunder. This Section
         2.5(g) shall apply to successive amendments to Rule 144(k) (or any
         successor rule) changing the holding period thereunder.

         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 request the Trustee or an authenticating
agent appointed by the Trustee shall authenticate and deliver, 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.

         The Trustee or such authenticating agent may authenticate any such
substituted Note and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating
agent may require. 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
called for redemption 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


                                      -22-

<PAGE>

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 definitive
Notes, the Company may execute and the Trustee or an authenticating agent
appointed by the Trustee shall, upon 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 definitive Notes 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 definitive Notes. Without unreasonable delay the Company will execute and
deliver to the Trustee or such authenticating agent definitive Notes (other than
in the case of Notes in global form) and thereupon any or all temporary Notes
(other than any the Global Note) may be surrendered in exchange therefor, at
each office or agency maintained by the Company pursuant to Section 5.2 and the
Trustee or such authenticating agent shall authenticate and deliver in exchange
for such temporary Notes an equal aggregate principal amount of definitive
Notes. 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 definitive Notes authenticated and delivered hereunder.

         Section 2.8 Cancellation of Notes Paid, Etc. All Notes surrendered for
the purpose of payment, redemption, 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. Upon written
instructions of the Company, the Trustee shall destroy canceled Notes and, after
such destruction, shall deliver a certificate of such destruction 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.

                               REDEMPTION OF NOTES

         Section 3.1 Redemption Prices. The Company may, at its option, redeem
all or from time to time any part of the Notes on any date prior to maturity,
upon notice as set forth in Section 3.2, and at the optional redemption prices
set forth in the form of Note attached as Exhibit A hereto, together with
accrued interest, if any, to, but excluding, the date fixed for redemption,
provided, however, that no such redemption shall be effected before May 4, 2001.

         Section 3.2 Notice of Redemption; Selection of Notes. In case the
Company shall desire to exercise the right to redeem all or, as the case may be,
any part of the Notes pursuant to Section 3.1, it shall fix a date for
redemption, and it, or at its request (which must be received by the Trustee at
least ten (10) Business Days prior to the date the Trustee is requested to give
notice as described below unless a shorter period is agreed to by the Trustee),
the Trustee in the name of and at the expense of the Company, shall mail or
cause to be mailed a notice of such redemption at least twenty (20) and not more
than sixty (60) days prior to the date fixed for redemption to the holders of
Notes so to be redeemed as a whole or in part at their last addresses as the
same appear on the Note register (provided that if the Company shall give such
notice, it shall also give such notice, and notice of the Notes to be redeemed,
to the Trustee). Such mailing shall be by first class mail. The notice if mailed
in the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the holder receives such notice. In any case, failure to
give such notice by mail or any defect in the notice to the holder of any Note
designated for redemption as a whole or in part shall not affect the validity of
the proceedings for the redemption of any other Note.

         Each such notice of redemption shall specify the aggregate principal
amount of Notes to be redeemed, the date fixed for redemption, the redemption
price at which Notes are to be redeemed, the place or places of payment, that
payment will be made upon presentation and surrender of such Notes, that
interest accrued to, but excluding, the date fixed for redemption will be paid
as specified in said notice, and that on and after said date interest thereon or
on the portion thereof to be redeemed will cease to accrue. Such notice shall
also state the current Conversion Price and the date on which the right to
convert such Notes or portions thereof into Common Stock will expire. If fewer
than all the Notes are to be redeemed, the notice of redemption shall identify
the Notes to be redeemed. In case any Note is to be redeemed in part only, the
notice of redemption shall state the portion of the principal amount thereof to
be redeemed and shall state that on and after the date fixed for redemption,
upon surrender of such Note, a new Note or Notes in principal amount equal to
the unredeemed portion thereof will be issued.

         On or prior to the redemption date specified in the notice of
redemption given as provided in this Section, 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


                                      -24-

<PAGE>



provided in Section 5.4) an amount of money sufficient to redeem on the
redemption date all the Notes (or portions thereof) so called for redemption
(other than those theretofore surrendered for conversion into Common Stock) at
the appropriate redemption price, together with accrued interest to, but
excluding, the date fixed for redemption; provided that if such payment is made
on the redemption date it must be received by the Trustee or paying agent, as
the case may be, by 10:00 a.m. New York City time, on such date. If any Note
called for redemption is converted pursuant hereto, any money deposited with the
Trustee or any paying agent or so segregated and held in trust for the
redemption of such Note shall be paid to the Company upon its request, or, if
then held by the Company shall be discharged from such trust.

         If fewer than all the Notes are to be redeemed, the Company will give
the Trustee written notice in the form of an Officers' Certificate not fewer
than thirty-five (35) days (or such shorter period of time as may be acceptable
to the Trustee) prior to the redemption date as to the aggregate principal
amount of Notes to be redeemed. If fewer than all the Notes are to be redeemed,
the Trustee shall select the Notes or portions thereof to be redeemed (in
principal amounts of $1,000 or integral multiples thereof), by lot, or by a
method the Trustee considers fair and appropriate (as long as such method is not
prohibited by the rules of any United States national securities exchange or of
an established automated over-the-counter trading market in the United States on
which the Notes are then listed). If any Note selected for partial redemption is
converted in part after such selection, the converted portion of such Note shall
be deemed (so far as is possible) to be the portion to be selected for
redemption. The Notes (or portions thereof) so selected shall be deemed duly
selected for redemption for all purposes hereof, notwithstanding that any such
Note is converted as a whole or in part before the mailing of the notice of
redemption.

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

         Section 3.3 Payment of Notes Called for Redemption. If notice of
redemption has been given as above provided, the Notes or portion of Notes with
respect to which such notice has been given shall, unless converted into Common
Stock pursuant to the terms hereof, become due and payable on the date and at
the place or places stated in such notice at the applicable redemption price,
together with interest accrued to, but excluding, the date fixed for redemption,
and on and after said date (unless the Company shall default in the payment of
such Notes at the redemption price, together with interest accrued to, but
excluding, said date) interest on the Notes or portion of Notes so called for
redemption shall cease to accrue and such Notes shall cease after the close of
business on the Business Day next preceding the date fixed for redemption to be
convertible into Common Stock and, except as provided in Sections 8.5 and 13.4,
to be entitled to any benefit or security under this Indenture, and the holders
thereof shall have no right in respect of such Notes except the right to receive
the redemption price thereof and unpaid interest


                                      -25-

<PAGE>



to, but excluding, the date fixed for redemption. On presentation and surrender
of such Notes at a place of payment in said notice specified, the said Notes or
the specified portions thereof to be redeemed shall be paid and redeemed by the
Company at the applicable redemption price, together with interest accrued
thereon to, but excluding, the date fixed for redemption; provided that, if the
applicable redemption date is an interest payment date, the semi-annual payment
of interest becoming due on such date shall be payable to the holders of such
Notes registered as such on the relevant record date subject to the terms and
provisions of Section 2.3 hereof.

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

         Notwithstanding the foregoing, the Trustee shall not redeem any Notes
or mail any notice of optional redemption during the continuance of a default in
payment of interest or premium on the Notes or of any Event of Default of which,
in the case of any Event of Default other than under Section 7.1(a), (b) or (d),
a Responsible Officer of the Trustee has knowledge. If any Note called for
redemption shall not be so paid upon surrender thereof for redemption, the
principal and premium, if any, shall, until paid or duly provided for, bear
interest from the date fixed for redemption at the rate borne by the Note and
such Note shall remain convertible into Common Stock until the principal and
premium, if any, shall have been paid or duly provided for.

         Section 3.4 Conversion Arrangement on Call for Redemption. In
connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes not converted prior to the expiration of
such conversion right by an agreement with one or more investment bankers or
other purchasers to purchase such Notes by paying to the Trustee in trust for
the Noteholders, on or before the date fixed for redemption, an amount not less
than the applicable redemption price, together with interest accrued to the date
fixed for redemption, of such Notes. Notwithstanding anything to the contrary
contained in this Article III, the obligation of the Company to pay the
redemption price of such Notes, together with interest accrued to, but
excluding, the date fixed for redemption, shall be deemed to be satisfied and
discharged to the extent such amount is so paid by such purchasers. If such an
agreement is entered into, a copy of which, certified as true and correct by the
Secretary or Assistant Secretary of the Company will be filed with the Trustee
prior to the date fixed for redemption, any Notes not duly surrendered for
conversion by the holders thereof may, at the option of the Company, be deemed,
to the fullest extent permitted by law, acquired by such purchasers from such
holders and (notwithstanding anything to the contrary contained in Article XV)
surrendered by such purchasers for conversion, all as of immediately prior to
the close of business on the date fixed for redemption (and the right to convert
any such Notes shall be deemed to have been extended through such time), subject
to payment of the above amount as aforesaid. At the direction of the Company,
the Trustee shall hold and dispose of any such amount paid to it in the same
manner as it would monies deposited with it by the Company for the redemption of
Notes. Without the Trustee's prior written consent, no arrangement between the
Company and such purchasers for


                                      -26-

<PAGE>



the purchase and conversion of any Notes shall increase or otherwise affect any
of the powers, duties, responsibilities or obligations of the Trustee as set
forth in this Indenture, and the Company agrees to indemnify the Trustee from,
and hold it harmless against, any loss, liability or expense arising out of or
in connection with any such arrangement for the purchase and conversion of any
Notes between the Company and such purchasers, including the costs and expenses
incurred by the Trustee in the defense of any claim or liability arising out of
or in connection with the exercise or performance of any of its powers, duties,
responsibilities or obligations under this Indenture.

                             SUBORDINATION OF NOTES

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

         The payment of the principal of, premium, if any, and interest on all
Notes (including, but not limited to, the redemption price or repurchase price
with respect to the Notes to be redeemed or repurchased, as provided in this
Indenture) issued hereunder shall, to the extent and in the manner hereinafter
set forth, be subordinated to the prior payment in full, in cash or in such
other form of payment as may be acceptable to the holders of Senior
Indebtedness, of all Senior Indebtedness, whether outstanding at the date of
this Indenture or thereafter incurred or created.

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

         Section 4.2 Payments to Noteholders. No payment (including pursuant to
any redemption or repurchase of Notes) shall be made with respect to the
principal of, or premium, if any, or interest (including Liquidated Damages, if
any) on the Notes, except payments and distributions made by the Trustee as
permitted by Section 4.6, if:

                  (1) a default in the payment of principal, premium, if any, or
         interest or other payment due on Designated Senior Indebtedness occurs
         and is continuing beyond any applicable period of grace; or

                  (2) any other default occurs and is continuing with respect to
         Designated Senior Indebtedness that then permits holders of the
         Designated Senior Indebtedness as to which such default related to
         accelerate its maturity and the Trustee and the Company receive a
         notice of such default (a "Payment Blockage Notice") from a
         representative of


                                      -27-

<PAGE>



         Designated Senior Indebtedness or a holder of Designated Senior
         Indebtedness or the Company.

         The Company may and shall resume payments on the Notes (1) in the case
of a payment default, on the date upon which such default is cured or waived or
ceases to exist, and (2) in the case of a nonpayment default with respect to
Designated Senior Indebtedness, on the earlier of the date on which the
nonpayment default is cured or waived or ceases to exist or 179 days pass after
the date on which the applicable Payment Blockage Notice is received.

         No new period of payment blockage may be commenced pursuant to a
Payment Blockage Notice unless (A) at least 365 days shall have elapsed since
the first day of effectiveness of the immediately prior Payment Blockage Notice
and (B) all scheduled payments of principal, premium, if any, and interest on
the Notes that have come due have been paid in full in cash, or in such other
form of payment as may be acceptable to the holders of the Notes. No default
(whether or not such event of default is on the same issue of Designated Senior
Indebtedness) that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

         In addition, in the event of any acceleration of the Notes because of
an Event of Default, no payment or distribution (including with respect to any
redemption or repurchase of the Notes) shall be made to the Trustee or any
holder of Notes with respect to the principal of, premium, if any, or interest
(including Liquidated Damages, if any) on the Notes, except payments and
distributions made by the Trustee as permitted by Section 4.6, until all Senior
Indebtedness has been paid in full in cash or other payment satisfactory to the
holders of Senior Indebtedness or such acceleration is rescinded in accordance
with the terms of this Indenture. If payment of the Notes is accelerated because
of an Event of Default, the Company shall promptly notify holders of Senior
Indebtedness of the acceleration.

         Notwithstanding the foregoing, in the event that the Trustee or any
holder of Notes receives any payment or distribution of assets of the Company of
any kind in contravention of any term of this Indenture, whether in cash,
property or securities, including, without limitation, by way of setoff or
otherwise, before all Senior Indebtedness is paid in full, in cash or such other
form of payment as may be acceptable to the holders of Senior Indebtedness, then
such payment or distribution shall be held by the recipient or recipients in
trust for the benefit of, and shall immediately be paid over or delivered to,
the holders of Senior Indebtedness or their respective representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness may have been issued,
as their respective interests may appear, as calculated by the Company, for
application to the payment of all Senior Indebtedness remaining unpaid to the
extent necessary to make payment in full, in cash or such other form of payment
as may be acceptable to the holders of Senior Indebtedness, of all Senior
Indebtedness remaining unpaid, after giving effect to any concurrent payment or
distribution, or provision therefor, to or for the holders of such Senior
Indebtedness.

         Nothing in this Section 4.2 shall apply to claims of, or payments to,
the Trustee pursuant to Section 8.6. This Section 4.2 shall be subject to the
further provisions of Section 4.6.

         Section 4.3 Bankruptcy and Dissolution, Etc. Upon any payment by the
Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to creditors upon any dissolution,
winding-up, liquidation or reorganization of the Company, whether voluntary or
involuntary or in bankruptcy, insolvency, receivership or other proceedings, all
amounts due or to become due upon all Senior Indebtedness shall first be paid in
full, in cash or in such other form of payment as may be acceptable to the
holders of Senior Indebtedness, before any payment is made on account of the
principal or premium, if any, and interest on the Notes (except payments made
pursuant to Article XIII from monies deposited with the Trustee pursuant thereto
prior to the happening of such dissolution, winding-up, liquidation or
reorganization or bankruptcy, insolvency, receivership or other such
proceedings); and upon any such dissolution, winding-up, liquidation or
reorganization or bankruptcy, insolvency, receivership or other such
proceedings, any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
which the holders of the Notes or the Trustee under this Indenture would be
entitled, except for the provision of this Article IV, shall (except as
aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other person making such payment or distribution,
or by the holders of the Notes or by the Trustee under this Indenture if
received by them or it, directly to the holders of Senior Indebtedness (pro rata
to such holders on the basis of the respective amounts of Senior Indebtedness
held by such holders, or as otherwise required by law or a court order) or their
respective representative or representatives, or to the trustee or trustees
under any indenture pursuant to which any instruments evidencing any Senior
Indebtedness may have been issued, as their respective interests may appear, to
the extent necessary to pay all Senior Indebtedness in full in cash or in such
other form of payment as may be acceptable to the holders of Senior Indebtedness
after giving effect to any concurrent payment or distribution to or for the
holders of Senior Indebtedness, before any payment or distribution is made to
the holders of the Notes or to the Trustee under this Indenture.

         Notwithstanding the foregoing, in the event that the Trustee or any
holder of Notes receives any payment or distribution of assets of the Company of
any kind in contravention of any term of this Indenture, whether in cash,
property or securities, including, without limitation, by way of setoff or
otherwise, before all Senior Indebtedness is paid in full, in cash or such other
form of payment as may be acceptable to the holders of Senior Indebtedness, then
such payment or distribution shall be held by the recipient or recipients in
trust for the benefit of, and shall immediately be paid over or delivered to,
the holders of Senior Indebtedness or their respective representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness may have been issued,
as their respective interests may appear, as calculated by the Company, for
application to the payment of all Senior Indebtedness remaining unpaid to the
extent necessary to make payment in full, in cash or such other form of payment
as may be acceptable to the holders of Senior Indebtedness, of all


                                      -29-

<PAGE>



Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution, or provision therefor, to or for the holders of such
Senior Indebtedness.

         For purposes of Section 4.2 hereof and this Section 4.3, the words
"cash, property or securities" shall not be deemed to include shares of stock of
the Company as reorganized or readjusted, or securities of the Company or any
other corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated (at least to the extent provided in this
Article IV with respect to the Notes) to the payment of all Senior Indebtedness
which may at the time be outstanding; provided that (i) the Senior Indebtedness
is assumed by the new corporation, if any, resulting from such reorganization or
adjustment, and (ii) the rights of the holders of Senior Indebtedness (other
than leases which are not assumed by the Company or by 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 corporation or the liquidation or
dissolution of the Company following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another corporation 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 4.3 if such other corporation shall, as a part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article
XII.

         Nothing in this Section 4.3 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 8.6. This Section 4.3 shall be subject
to the further provisions of Section 4.6.

         Section 4.4 Subrogation of Notes. Subject to the payment in full in
cash or in such other form of payment as may be acceptable to the holders of
Senior Indebtedness of all Senior Indebtedness, the rights of the holders of the
Notes shall be subrogated to the extent of the payments or distributions made to
the holders of such Senior Indebtedness pursuant to the provisions of this
Article IV (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to other indebtedness of the
Company to substantially the same extent as the Notes are subordinated and is
entitled to like rights of subrogation) to the rights of the holders of Senior
Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to the Senior Indebtedness until the
principal of, and premium, if any, and interest on the Notes shall be paid in
full; and, for the purposes of such subrogation, no payments or distributions to
the holders of the Senior Indebtedness of any cash, property or securities to
which the holders of the Notes or the Trustee would be entitled except for the
provisions of this Article IV, and no payment over pursuant to the provisions of
this Article IV, to or for the benefit of the holders of Senior Indebtedness by
holders of the Notes or the Trustee, shall, as between the Company, its
creditors other than holders of Senior Indebtedness, and the holders of the
Notes, be deemed to be a payment by the Company to or on account of the Senior
Indebtedness; and no payments or distributions of cash, property or securities
to or for the benefit of the holders of the Notes pursuant to the subrogation
provisions of this Article IV, which would otherwise have been paid to the
holders of Senior Indebtedness shall be deemed to be a payment by the Company to
or for the account of the


                                      -30-

<PAGE>



Notes. It is understood that the provisions of this Article IV are and are
intended solely for the purposes of defining the relative rights of the holders
of the Notes, on the one hand, and the holders of the Senior Indebtedness, on
the other hand.

         Nothing contained in this Article IV or elsewhere in this Indenture or
in the Notes is intended to or shall impair, as among the Company, its creditors
other than the holders of Senior Indebtedness, and the holders of the Notes, the
obligation of the Company, which is absolute and unconditional, to pay to the
holders of the Notes the principal of, 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 the Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or the
holder of any Note from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article IV of the holders of Senior Indebtedness in respect of cash,
property or securities of the Company received upon the exercise of any such
remedy.

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

         Section 4.5 Authorization by Noteholders. Each holder of a Note by his
acceptance thereof authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Article IV and appoints the Trustee his attorney-in-fact for
any and all such purposes. If the Trustee does not file a proper proof of claim
or proof of debt in the form required in any proceeding referred to in the third
paragraph of Section 7.2 hereof at least thirty (30) days before the expiration
of the time to file such claim, the holders of any Senior Indebtedness or their
representatives are hereby authorized to file an appropriate claim for and on
behalf of the holders of the Notes.

         Section 4.6 Notice to Trustee. The Company shall give written notice to
the Trustee of the issuance of any Designated Senior Indebtedness. In addition,
the Company shall give prompt written notice in the form of an Officers'
Certificate to a Responsible Officer of the Trustee and to any paying agent of
any fact known to the Company which would prohibit the making of any payment of
monies to or by the Trustee or any paying agent in respect of the Notes pursuant
to the provisions of this Article IV. Notwithstanding the provisions of this
Article IV or any other provision of this Indenture, the Trustee shall not be
charged with


                                      -31-

<PAGE>



knowledge of the existence of any Senior Indebtedness or of any default or event
of default with respect to any Senior Indebtedness or of any other facts which
would prohibit the making of any payment of monies to or by the Trustee in
respect of the Notes pursuant to the provisions of this Article IV, unless and
until a Responsible Officer of the Trustee shall have received written notice
thereof at the Corporate Trust Office from the Company (in the form of an
Officers' Certificate) or a holder or holders of Senior Indebtedness or from any
trustee thereof who shall have been certified by the Company or otherwise
established to the reasonable satisfaction of the Trustee to be such holder or
trustee; and before the receipt of any such written notice, the Trustee, subject
to the provisions of Section 8.1, shall be entitled in all respects to assume
that no such facts exist; provided that if on a date at least two (2) Business
Days prior to the date upon which by the terms hereof any such monies may become
payable for any purpose (including, without limitation, the payment of the
principal of, or premium, if any, or interest on any Note), the Trustee shall
not have received with respect to such monies the notice provided for in this
Section 4.6, then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such monies and to
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 prior date.

         Notwithstanding anything to the contrary hereinbefore set forth,
nothing shall prevent (a) any payment by the Company or the Trustee to the
Noteholders of amounts in connection with a redemption of Notes if (i) notice of
such redemption has been given to the Noteholders pursuant to Article III prior
to the receipt by the Trustee of written notice as aforesaid, and (ii) such
notice of redemption is given not earlier than sixty (60) days before the
redemption date, (b) any payment by the Company or the Trustee to the
Noteholders of amounts in connection with a repurchase of Notes if (i) notice of
such repurchase has been given pursuant to Article XVI prior to the receipt by
the Trustee of written notice as aforesaid, and (ii) such notice of repurchase
is given not earlier than forty (40) days before the repurchase date, or (c) any
payment by the Trustee to the Noteholders of monies deposited with it pursuant
to Section 13.1.

         The Trustee, subject to the provisions of Section 8.1, shall be
entitled to rely on the delivery to it of a written notice by a person
representing himself to be a holder of Senior Indebtedness (or a trustee on
behalf of such holder) to establish that such notice has been given by a holder
of Senior Indebtedness or a trustee on behalf of any such holder or holders. In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article IV, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such person, the extent to which such person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such person under this Article IV, and if such evidence is not furnished the
Trustee may defer any payment to such person pending judicial determination as
to the right of such person to receive such payment.

         Section 4.7 Trustee's Relation to Senior Indebtedness. The Trustee and
any agent of the Company or the Trustee in its individual capacity shall be
entitled to all the rights set forth in this Article IV in respect of any Senior
Indebtedness at any time held by it, to the same extent as any other holder of
Senior Indebtedness, and nothing in Section 8.13 or elsewhere in this Indenture
shall deprive the Trustee or any such agent of any of its rights as such holder.
Nothing in this Article IV shall apply to claims of, or payments to, the Trustee
under or pursuant to Section 8.6.

         With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article IV, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and, subject to the
provisions of Section 4.2 and Section 8.1, the Trustee shall not be liable to
any holder of Senior Indebtedness if it shall pay over or deliver to holders of
Notes, the Company or any other person money or assets to which any holder of
Senior Indebtedness shall be entitled by virtue of this Article IV or otherwise.

         Section 4.8 No Impairment of Subordination. No right of any present or
future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof which any such holder may have or otherwise be charged with.

         Section 4.9 Certain Conversions 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 (or premium,
if any) or interest on Notes or on account of the purchase or other acquisition
of Notes, and (2) the payment, issuance or delivery of cash, property or
securities (other than junior securities) upon conversion of a Note shall be
deemed to constitute payment on account of the principal of such Note. For the
purposes of this Section, the term "junior securities" means (a) shares of any
stock of any class of the Company and (b) securities of the Company which are
subordinated in right of payment to all Senior Indebtedness which may be
outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Notes are so
subordinated as provided in this Article. Nothing contained in this Article 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 Indebtedness and
the holders of the Notes, the right, which is absolute and unconditional, of the
holder of any Note to convert such Note in accordance with Article XV.

         Section 4.10 Article Applicable to Paying Agents. If at any time any
paying agent other than the Trustee shall have been appointed by the Company and
be then acting hereunder, the


                                      -33-

<PAGE>



term Trustee as used in this Article IV shall (unless the context shall
otherwise require) be construed as extending to and including such paying agent
within its meaning as fully for all intents and purposes as if such paying agent
were named in this Article in addition to or in place of the Trustee; provided,
however, that the first sentence of Section 4.5 shall not apply to the Company
or any Affiliate of the Company if it or such Affiliate acts as paying agent.


                                    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, and interest 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 by mailing checks for the interest payable to or upon
the written order of the holders of Notes entitled thereto as they shall appear
on the registry books of the Company, provided that, with respect to any holder
of Notes with an aggregate principal amount equal to or in excess of $5,000,000,
at the request of such holder in writing to the Company, interest on such
holder's Notes shall be paid by wire transfer in immediately available funds in
accordance with the wire transfer instructions supplied by such holder from time
to time to the Trustee and paying agent (if different from Trustee) at least two
days prior to the applicable record date.

         Section 5.2 Maintenance of Office or Agency. The Company will maintain
in the Borough of Manhattan, The City of New York, an office or agency where the
Notes may be surrendered for registration of transfer or exchange or for
presentation for payment or for conversion, redemption 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.

         The Company may also from time to time designate 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; provided
that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in the Borough of Manhattan,
The City of New York, for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.


                                      -34-

         The Company hereby initially designates the Trustee as paying agent,
Note registrar, Custodian and conversion agent and the Corporate Trust Office
and the office or agency of the Trustee in the Borough of Manhattan, The City of
New York (which initially shall be First National Bank of Chicago, an agency of
the Trustee located at 14 Wall Street, 8th Floor, New York, New York 10005) 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

third paragraph of Section 8.11.

         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:

                           (1) 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;

                           (2) 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

                           (3) 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 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
         must be received by the paying agent by 10:00 a.m., New York City time,
         on such date.



                                      -35-

                  (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

         of the principal of, premium, if any, or interest 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

the extent that it may lawfully do so) that it shall not at any time insist

law which would prohibit or forgive the Company from paying all or any portion

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
has been enacted.

         Section 5.8 Compliance Certificate. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company
(beginning with the fiscal year ending on July 31, 1998) an Officers'
Certificate stating whether or not to the best of their knowledge the signers
know of any default or Event of Default that occurred during such period. If
they do, such Officers' Certificate shall describe the default or Event of
Default and its status.

the Company will execute and deliver such further instruments and do such
further acts as may be reasonably necessary or proper to carry out more

         is a "Notice of Default" hereunder; or

                  (g) default on the part of the Company or any Significant

         hereunder; or

                  (h) the Company or any Significant Subsidiary shall commence a
         voluntary case or other proceeding seeking liquidation, reorganization
         or other relief with respect to itself 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
         its property, 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

         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
         its property, and such involuntary case or other proceeding shall
         remain undismissed and unstayed for a period of ninety (90) consecutive
         days, unless being contested in good faith by the Company, or (y) an


                                      -40-

<PAGE>



         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 its property, 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(h) or (i) with respect to the Company), 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 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 interest
accrued thereon 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(h) or (i) occurs and is continuing with
respect to the Company, the principal of all the Notes and the interest accrued
thereon shall be immediately due and payable. 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 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 (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 interest on 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 the Responsible Officer of
the Trustee, promptly upon becoming aware thereof, of any default or Event of
Default and shall deliver to the Trustee a statement specifying such default or
Event of Default and the action the Company has taken, is taking or proposes to
take with respect thereto.

         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


                                      -41-

<PAGE>



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 instituted.

         Section 7.2 Payments of Notes on Default; Suit Therefor. The Company
covenants that (a) in case default shall be made in the payment by the Company
of any installment of interest upon 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 redemption or repurchase, by declaration under this Indenture 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, or both, 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
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, attorneys and counsel, and
any expenses or liabilities incurred by the Trustee hereunder other than through
its negligence or bad faith. Until such demand by the Trustee, the Company may
pay the principal of and premium, if any, and interest on 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 owing and unpaid in respect of


                                      -42-

<PAGE>



the Notes, and, in case of any judicial proceedings, to file such proofs of
claim and other papers or documents and to take such other actions as it may
deem 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 agents and 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 on 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 interest on 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


                                      -43-

<PAGE>



         overdue installments of interest 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 interest, 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 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
         without preference or priority of principal and premium, if any, over
         interest, or of interest 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 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 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 indemnity as may be
reasonably satisfactory to the Trustee 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.



                                      -44-

         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, and interest on such Note, on or after the
respective due dates expressed in such Note, 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 his own behalf and for his own
benefit, may enforce, and may institute and maintain any proceeding suitable to
enforce, his 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 the Trustee
shall deem most effectual to protect and enforce any of such rights, either by
suit in equity or by action at law or by proceeding in bankruptcy or otherwise,
whether for the specific enforcement of any covenant or agreement contained in
this Indenture or in aid of the exercise of any power granted in this Indenture,
or to enforce any other legal or equitable right vested in the Trustee by this
Indenture or by law.

         Section 7.6 Remedies Cumulative and Continuing. Except as provided in
the last paragraph of 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 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, and (b) the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. 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 when due, (ii) a failure


                                      -45-

<PAGE>



by the Company to convert any Notes into Common Stock or (iii) 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. 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 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 on any of the Notes, including without limiting the generality of the
foregoing any default in the payment of any Repurchase Price or in the payment
of any amount due in connection with any redemption of Notes, then in any such
event 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 determine 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 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 10% 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 (including, but
not limited to, the redemption price or repurchase price with respect to the
Notes being redeemed or repurchased as provided in this Indenture) 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.

         Section 7.10 Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any holder of any Note to exercise any right or remedy accruing
upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or any acquiescence therein. Every right and
remedy given by this Article or by law to the Trustee or to


                                      -46-

<PAGE>



the holders of Notes may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the holders of Notes, as the case may be.


                                  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 or waiver 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 person
would exercise or use under the circumstances in the conduct of such person's
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:

                           (1) the duties and obligations of the Trustee shall
                  be determined solely by the express provisions of this
                  Indenture and, after it has been qualified thereunder, 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

                           (2) 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 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 it shall be provided that the Trustee was negligent in
         ascertaining the pertinent facts;



                                      -47-

<PAGE>



                  (c) the Trustee shall not be liable to any Noteholder with
         respect to any action taken or omitted to be taken by it in good faith
         in accordance with the 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; and

                  (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.

                  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, 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 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 of
         such counsel 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;



                                      -48-

<PAGE>



                  (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; provided, however, that if
         the payment within a reasonable time to the Trustee of the costs,
         expenses or liabilities likely to be incurred by it in the making of
         such investigation is, in the opinion of the Trustee, not reasonably
         assured to the Trustee by the security afforded to it by the terms of
         this Indenture, the Trustee may require indemnity reasonably
         satisfactory to the Trustee from the Noteholders against such expenses
         or liability as a condition to so proceeding; the reasonable expenses
         of every such examination shall be paid by the Company or, if paid by
         the Trustee or any predecessor Trustee, shall be repaid by the Company
         upon demand; 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.

In no event shall the Trustee be liable for any consequential loss or damage of
any kind whatsoever (including but not limited to lost profits), even if the
Trustee has been advised of the likelihood of such loss or damage and regardless
of the form of action other than through the Trustee's willful misconduct or
gross negligence.

         Section 8.3 No Responsibility 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, 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


                                      -49-

<PAGE>



under no liability for interest on any money received by it hereunder except as
may be agreed from time to time by the Company and the Trustee.

         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), 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 agents and
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 or
bad faith. The Company also covenants to indemnify 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 or bad faith on the part of the Trustee or such
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, subject to the effect of Sections 4.3
and 7.6, funds held in trust herewith for the benefit of the holders of
particular Notes prior to the date of the accrual of such unpaid compensation or
indemnifiable claim. The obligation of the Company under this Section shall
survive the satisfaction and discharge of this Indenture. The indemnification
provided in this Section 8.6 shall extend to the officers, directors, agents and
employees of the Trustee.

         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(h) or (i) 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
and bad faith on the part of the Trustee, be deemed to be conclusively proved
and established by an Officers' Certificate delivered to the Trustee, and such
Officers' Certificate, in the absence of negligence, willful misconduct,
recklessness and bad faith on the part of the Trustee, shall be full warrant to
the Trustee for any action taken or omitted by it under the provisions of this
Indenture upon the faith thereof.

<PAGE>



         Section 8.8 Conflicting Interests of Trustee. After qualification under
the Trust Indenture Act, 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 combined capital and surplus (together
with its corporate parent) 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 by mailing notice thereof
         to the holders of Notes at their addresses as they shall appear on the
         Note register. 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 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:

                           (1) the Trustee shall fail to comply with Section 8.8
                  within a reasonable time 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 months, or

                           (2) 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


                                      -51-

<PAGE>



                           (3) 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, or

                           (4) there shall be an unreasonable increase in the
                  fees of the Trustee, or

                           (5) a successor in interest to the entity serving as
                  Trustee, by reason of merger or consolidation, shall be
                  reasonably unacceptable to the Company or to the holders of at
                  least 51% in principal amount of the outstanding Notes,

         then, in any such case, the Company may by a Board resolution 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 months may, on behalf of himself and all others
         similarly situated, petition any court of competent jurisdiction for
         the removal of the Trustee and the 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, 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


                                      -52-

<PAGE>



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, each of the Company and the former trustee 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 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 or other entity
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 or other
entity succeeding to all or substantially all of the corporate trust business of
the Trustee, 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 an authenticating agent appointed by such successor
trustee may authenticate such Notes either in the name of any predecessor
trustee hereunder or in the name of the successor trustee; and in all such cases
such certificates shall have the full force which it is anywhere in the Notes or
in this Indenture provided that the certificate of the Trustee shall have;
provided, however, that the right to adopt the certificate of authentication of
any predecessor Trustee or to 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 Limitation on Rights of Trustee as Creditor. If and when
the Trustee shall be or become a creditor of the Company (or any other obligor
upon the Notes), after qualification under the Trust Indenture Act, 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).


                                   ARTICLE IX

                           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 his 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 Note register 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 authenticating agent, 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 him 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,


                                      -54-

<PAGE>



waiver or other action under this Indenture, Notes which are owned by the
Company or any other obligor on the Notes or by any person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any other obligor on the Notes shall be disregarded
and deemed not to be outstanding for the purpose of any such determination;
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 a person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or 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

indenture executed pursuant to the provisions of this Article XI shall comply
with the Trust Indenture Act, as then in effect. Upon the execution of any

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

         Section 12.2 Successor Corporation to Be Substituted. In case of any
such consolidation, merger, sale, conveyance or lease in accordance with Section
12.1, and, where required in accordance with Section 12.1(a) upon the assumption
by the successor corporation, 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
corporation 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 corporation thereupon may cause to be signed, and may issue either in
its own name or in the name of Financial Federal 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
corporation 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
corporation thereafter shall cause to be signed and delivered to the Trustee for
that purpose. All the Notes 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,
subject to Sections 8.1 and 8.2, 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


                                      -62-

<PAGE>



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 or are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption,
and the Company shall deposit with the Trustee, in trust, funds sufficient to
pay at maturity or upon redemption 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 or redemption date, as the case may be, and if in either case 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 demand of the Company accompanied by an Officers' Certificate and an Opinion
of Counsel as required by Section 17.5 and at the cost and expense of the
Company, shall execute proper instruments acknowledging satisfaction of and
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
shall be held in trust and applied by it to the payment, notwithstanding the
provisions of Article IV, 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 or redemption 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 demand 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


                                      -63-

<PAGE>



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 (i) 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 and (ii) the holders of at least a
majority in principal amount of the then outstanding Notes so request by written
notice to the Trustee, 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
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; 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, the holder of any Note shall have the right, at
his option, at any time following the date of original issuance of the Notes and
prior to the close of business on May 1, 2005 (except that, with respect to any
Note or portion of a Note which shall be called for redemption, such right shall
terminate, except as provided in the fifth paragraph of Section 15.2 and Section
3.4, at


                                      -64-

<PAGE>



the close of business on the Business Day next preceding the date fixed for
redemption of such Note or portion of a Note unless the Company shall default in
payment due upon redemption thereof) 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, into that number of fully paid and non-assessable shares of
Common Stock (as such shares shall then be constituted) obtained by dividing the
principal amount of the Note or portion thereof surrendered for conversion by
the Conversion Price in effect at such time, by surrender of the Note so to be
converted in whole or in part in the manner provided in Section 15.2. 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. A
Note with respect to which a holder has delivered a notice in accordance with
Section 16.2 regarding such holder's election to require the Company to
repurchase such holder's Notes following the occurrence of a Repurchase Event
may be converted in accordance with this Article XV only if such holder
withdraws such notice by delivering a written notice of withdrawal to the
Company prior to the close of business on last Business Day prior to the day
fixed for repurchase.

         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 definitive 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 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
such portion thereof specified in said notice. Such notice shall also state the
name or names (with address) 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 the Global Note, the beneficial holder must complete the appropriate
instruction form for conversion pursuant to the Depositary's book-entry
conversion program, deliver by book-entry delivery an interest in the Global
Note, 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 the penultimate paragraph of 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


                                      -65-

<PAGE>



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 (which payment, if any, shall be paid no later than
five Business Days after satisfaction of the requirements for conversion set
forth above). 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 Price 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 through the close of business on the Business Day next preceding such
interest payment date shall (unless such Note or portion thereof being converted
shall have been called for redemption pursuant to a redemption notice mailed to
the Noteholders in accordance with Section 3.2) be accompanied by payment, in
New York Clearing House funds or other funds acceptable to the Company, of an
amount equal to the interest otherwise payable on such interest payment date on
the principal amount being converted; provided, however, that no such payment
need be made if there shall exist at the time of conversion a default in the
payment of interest on the Notes. Except as provided above in this Section 15.2,
no adjustment shall be made for interest accrued on any Note converted or for
dividends on any shares issued upon the conversion of such Note as provided in
this Article.

         Upon the conversion of an interest in the Global Note, the Trustee, or
the Custodian at the direction of the Trustee, shall make a notation on the
Global Note as to the reduction in the principal amount represented thereby.

         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.


                                      -66-

<PAGE>



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
for conversion. If any fractional share of stock otherwise would be issuable
upon the conversion of any Note or Notes, the Company shall make an adjustment
therefor in cash at the current market value thereof to the holder of Notes. The
current market value of a share of Common Stock shall be the Closing Price on
the first Trading Day immediately preceding the day on which the Notes (or
specified portions thereof) are deemed to have been converted and such Closing
Price shall be determined as provided in Section 15.5(h).

         Section 15.4 Conversion Price. The conversion price shall be as
specified in the form of Note (herein called the "Conversion Price") attached as
Exhibit A hereto, subject to adjustment as provided in this Article XV.

         Section 15.5 Adjustment of Conversion Price. The Conversion Price 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 Price in effect at the opening of
         business on the date following the date fixed for the determination of
         stockholders entitled to receive such dividend or other distribution
         shall be reduced by multiplying such Conversion Price by a fraction of
         which the numerator shall be the number of shares of Common Stock
         outstanding at the close of business on the Record Date (as defined in
         Section 15.5(h)) fixed for such determination and the denominator shall
         be the sum of such number of shares and the total number of shares
         constituting such dividend or other distribution, such reduction to
         become effective immediately after the opening of business on the day
         following the Record Date. If any dividend or distribution of the type
         described in this Section 15.5(a) is declared but not so paid or made,
         the Conversion Price shall again be adjusted to the Conversion Price
         which 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
         the 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 in
         Section 15.5(h)) on the Record Date fixed for the determination of
         stockholders entitled to receive such rights or warrants, the
         Conversion Price shall be adjusted so that the same shall equal the
         price determined by multiplying the Conversion Price in effect at the
         opening of business on the date after such Record Date by a fraction of
         which the numerator shall be the number of shares of Common Stock
         outstanding at the close of business on the Record Date plus the number
         of shares which the aggregate offering price of the total number of
         shares so offered for subscription or purchase would purchase at such
         Current Market Price, and of


                                      -67-

<PAGE>



         which the denominator shall be the number of shares of Common Stock
         outstanding on the close of business on the Record Date plus the total
         number of additional shares of Common Stock so offered for subscription
         or purchase. Such adjustment shall become effective immediately after
         the opening of business on the day following the Record Date fixed for
         determination of stockholders entitled to receive such rights or
         warrants. To the extent that shares of Common Stock are not delivered
         pursuant to such rights or warrants, upon the expiration or termination
         of such rights or warrants the Conversion Price shall be readjusted to
         the Conversion Price 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 Price shall again be adjusted to be the Conversion Price
         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 for such rights or warrants,
         the value of such consideration, if other than cash, to be determined
         by the Board of Directors.

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

                  (d) In case the Company shall, by dividend or otherwise,
         distribute to all holders of its Common Stock 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,
         cash or other assets (including securities, but excluding (1) any
         rights or warrants referred to in Section 15.5(b) and, (2) dividends
         and distributions (A) in connection with the liquidation, dissolution
         or winding up of the Company or paid (B) exclusively in cash and (3)
         any capital stock, evidences of indebtedness, cash or assets
         distributed upon a merger or consolidation to which Section 15.6
         applies) (the foregoing hereinafter in this Section 15.5(d) called the
         "Securities")), unless the Company elects to reserve such Securities
         for distribution to the Noteholders upon 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


                                      -68-

<PAGE>



         Notes into Common Stock immediately prior to the Record Date (as
         defined in Section 15.5(h) for such distribution of the Securities)
         then, in each such case, the Conversion Price shall be reduced so that
         the same shall be equal to the price determined by multiplying the
         Conversion Price in effect immediately prior to the close of business
         on the Record Date (as defined in Section 15.5(h)) with respect to such
         distribution by a fraction of which the numerator shall be the Current
         Market Price (determined as provided in Section 15.5(h)) on such date
         less the fair market value (as determined by the Board of Directors,
         whose determination shall be conclusive and described in a Board
         Resolution) on such date of the portion of the Securities so
         distributed applicable to one share of Common Stock and the denominator
         shall be such Current Market Price, such reduction to become effective
         immediately prior to the opening of business on the day following the
         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 on the 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 of a Note
         (or any portion thereof) the amount of Securities such holder would
         have received had such holder converted such Note (or portion thereof)
         immediately prior to such Record Date. In the event that such dividend
         or distribution is not so paid or made, the Conversion Price shall
         again be adjusted to be the Conversion Price 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 comprising all or part of such
         distribution, it must in doing so consider the prices in such market
         over the same period (the "Reference Period") used in computing the
         Current Market Price pursuant to Section 15.5(h) to the extent
         possible, unless the Board of Directors in a board resolution
         determines in good faith that determining the fair market value during
         the Reference Period would not be in the best interest of the
         Noteholder.

                  In the event that the Company implements a stockholder rights
         plan, such rights plan shall provide that upon conversion of the Notes
         the holders will receive, in addition to the Common Stock issuable upon
         such conversion, the rights issued under such rights plan
         (notwithstanding the occurrence of an event causing such rights to
         separate from the Common Stock at or prior to the time of conversion).
         Any distribution of rights or warrants pursuant to a stockholder rights
         plan complying with the requirements set forth in the immediately
         preceding sentence of this paragraph shall not constitute a
         distribution of rights or warrants for the purposes of this Section
         15.5(d).

                  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


                                      -69-

<PAGE>



         issued in respect of future issuances of Common Stock, shall be deemed
         not to have been distributed for purposes of this Section 15.5(d) (and
         no adjustment to the Conversion Price under this Section 15.5(d) will
         be required) until the occurrence of the earliest Trigger Event. If
         such right or warrant is subject to subsequent events, upon the
         occurrence of which such right or warrant shall become exercisable to
         purchase different securities, evidences of indebtedness or other
         assets or entitle the holder to purchase a different number or amount
         of the foregoing or to purchase any of the foregoing at a different
         purchase price, then the occurrence of each such event shall be deemed
         to be the date of issuance and record date with respect to a new right
         or warrant (and a termination or expiration of the existing right or
         warrant without exercise by the holder 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 resulted in an
         adjustment to the Conversion Price under this Section 15.5(d), (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 Price shall be readjusted upon such final redemption or
         repurchase to give effect to such distribution or Trigger Event, as the
         case may be, as though it were a cash distribution, equal to the per
         share redemption or repurchase price received by a holder 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 all of which shall have expired or been
         terminated without exercise, the Conversion Price shall be readjusted
         as if such rights and warrants had never been issued.

                  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 to which
         Section 15.5(b) applies (or both), shall be deemed instead to be (1) a
         dividend or distribution of the evidences of indebtedness, assets,
         shares of capital stock, rights or warrants other than such shares of
         Common Stock or rights or warrants to which Section 15.5(b) applies
         (and any Conversion Price reduction 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
         Price reduction 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", "Record Date fixed for such
         determination" and "Record Date" within the meaning of Section 15.5(a)
         and as "the date fixed for the determination of stockholders entitled
         to receive such rights or warrants", "the Record Date fixed for the
         determination of the stockholders entitled to receive such rights or
         warrants" and "such Record Date" within the meaning of Section 15.5(b)
         and (B) any shares of Common Stock included in


                                      -70-

<PAGE>



         such dividend or distribution shall not be deemed "outstanding at the
         close of business on the Record 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 any cash
         that is distributed upon a merger or consolidation to which Section
         15.6 applies or as part of a distribution referred to in Section
         15.5(d)), in an aggregate amount that, combined together with (1) the
         aggregate amount of any other such distributions to all holders of its
         Common Stock made exclusively in cash within the twelve (12) months
         preceding the date of payment of such distribution, and in respect of
         which no adjustment pursuant to this Section 15.5(e) has been made, and
         (2) the aggregate of any cash plus the fair market value (as determined
         by the Board of Directors, whose determination shall be conclusive and
         described in a Board Resolution) of consideration payable in respect of
         any tender offer by the Company or any of its subsidiaries for all or
         any portion of the Common Stock concluded within the twelve (12) months
         preceding the date of payment of such distribution, and in respect of
         which no adjustment pursuant to Section 15.5(f) has been made, exceeds
         10% of the product of the Current Market Price (determined as provided
         in Section 15.5(h)) on the Record Date with respect to such
         distribution times the number of shares of Common Stock outstanding on
         such date, then, and in each such case, immediately after the close of
         business on such date, the Conversion Price shall be reduced so that
         the same shall equal the price determined by multiplying the Conversion
         Price in effect immediately prior to the close of business on such
         Record Date by a fraction (i) the numerator of which shall be equal to
         the Current Market Price on the Record Date less an amount equal to the
         quotient of (x) the excess of such combined amount over such 10% and
         (y) the number of shares of Common Stock outstanding on the Record Date
         and (ii) the denominator of which shall be equal to the Current Market
         Price on such 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 the 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 of a Note (or any portion thereof) the amount
         of cash such holder would have received had such holder converted such
         Note (or portion thereof) immediately prior to such Record Date. In the
         event that such dividend or distribution is not so paid or made, the
         Conversion Price shall again be adjusted to be the Conversion Price
         which would then be in effect if such dividend or distribution had not
         been declared. Any cash distribution to all holders of Common Stock as
         to which the Company makes the election permitted by Section 15.5(n)
         and as to which the Company has complied with the requirements of such
         Section shall be treated as not having been made for all purposes of
         this Section 15.5(e)).

                  (f) In case a tender offer made by the Company or any
         Subsidiary for all or any portion of the Common Stock shall expire and
         such tender offer (as amended upon the expiration thereof) shall
         require the payment to stockholders (based on the acceptance (up to any
         maximum specified in the terms of the tender offer) of Purchased Shares
         (as


                                      -71-

<PAGE>



         defined below)) of an aggregate consideration having a fair market
         value (as determined by the Board of Directors, whose determination
         shall be conclusive and described in a Board Resolution) that combined
         together with (1) the aggregate of the cash plus the fair market value
         (as determined by the Board of Directors, whose determination shall be
         conclusive and described in a Board Resolution), as of the expiration
         of such tender offer, of consideration payable in respect of any other
         tender offers, by the Company or any of its subsidiaries for all or any
         portion of the Common Stock expiring within the twelve (12) months
         preceding the expiration of such tender offer and in respect of which
         no adjustment pursuant to this Section 15.5(f) has been made and (2)
         the aggregate amount of any distributions to all holders of the
         Company's Common Stock made exclusively in cash within twelve (12)
         months preceding the expiration of such tender offer and in respect of
         which no adjustment pursuant to Section 15.5(e) has been made, exceeds
         10% of the product of the Current Market Price (determined as provided
         in Section 15.5(h)) as of the last time (the "Expiration Time") tenders
         could have been made pursuant to such tender offer (as it may be
         amended) times the number of shares of Common Stock outstanding
         (including any tendered shares) on the Expiration Time, then, and in
         each such case, immediately prior to the opening of business on the day
         after the date of the Expiration Time, the Conversion Price shall be
         adjusted so that the same shall equal the price determined by
         multiplying the Conversion Price in effect immediately prior to close
         of business on the date of the Expiration Time by a fraction of which
         the numerator shall be the number of shares of Common Stock outstanding
         (including any tendered shares) on the Expiration Time multiplied by
         the Current Market Price of the Common Stock on the Trading Day next
         succeeding the Expiration Time and the denominator 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 offer) of all shares
         validly tendered 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) on the Expiration
         Time and the Current Market Price of the Common Stock on the Trading
         Day next succeeding the Expiration Time, such reduction (if any) to
         become effective immediately prior to the opening of business on the
         day following the Expiration Time. In the event that the Company is
         obligated to purchase shares pursuant to any such tender offer, but the
         Company is permanently prevented by applicable law from effecting any
         such purchases or all such purchases are rescinded, the Conversion
         Price shall again be adjusted to be the Conversion Price which would
         then be in effect if such tender offer had not been made. If the
         application of this Section 15.5(f) to any tender offer would result in
         an increase in the Conversion Price, no adjustment shall be made for
         such tender offer under this Section 15.5(f). Any cash distribution to
         all holders of Common Stock as to which the Company has made the
         election permitted by Section 15.5(n) and as to which the Company has
         complied with the requirements of such Section shall be treated as not
         having been made for all purposes of this Section 15.5(f).

                  (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 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 "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 Expiration Time, and in which, as
         of the Expiration Time the Board of Directors is not recommending
         rejection of the offer, the Conversion Price shall be reduced so that
         the same shall equal the price determined by multiplying the Conversion
         Price in effect immediately prior to the Expiration Time by a fraction
         of which the numerator shall be the number of shares of Common Stock
         outstanding (including any tendered or exchanged shares) on the
         Expiration Time multiplied by the current Market Price of the Common
         Stock on the Trading Day next succeeding the Expiration Time and the
         denominator 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) on the Expiration
         Time and the Current Market Price of the Common Stock on the Trading
         Day next succeeding the Expiration Time, such reduction to become
         effective immediately prior to the opening of business on the day
         following the 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 Price shall again be adjusted to be the Conversion Price
         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 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:

                           (1) "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 on the American Stock Exchange or Nasdaq
                  National Market, as applicable, or, if such security is not
                  listed or admitted to trading on such National Market or
                  Exchange, on the principal national security exchange or


                                      -73-

<PAGE>



                  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, whose
                  determination shall be conclusive and described in a Board
                  Resolution.

                           (2) "Current Market Price" shall mean the average of
                  the daily Closing Prices per share of Common Stock for the ten
                  (10) 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 requiring such computation) that requires an
                  adjustment to the Conversion Price pursuant to Section
                  15.5(a), (b), (c), (d), (e), (f) or (g) occurs during such ten
                  (10) consecutive Trading Days, the Closing Price for each
                  Trading Day prior to the "ex" date for such other event shall
                  be adjusted by multiplying such Closing Price by the same
                  fraction by which the Conversion Price 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 or distribution
                  requiring such computation) that requires an adjustment to the
                  Conversion Price 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 multiplying 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 or distribution 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 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 Board Resolution) 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 Sections 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 offer requiring such computation)
                  that requires an adjustment to the Conversion Price


                                      -74-

<PAGE>



                  pursuant to Section 15.5(a), (b), (c), (d), (e), (f) and (g)
                  occurs on or after the Expiration Time 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
                  multiplying 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. 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 Expiration Time of such offer.
                  Notwithstanding the foregoing, whenever successive adjustments
                  to the Conversion Price are called for pursuant to this
                  Section 15.5, such adjustments shall be made to the Current
                  Market Price as may be necessary or appropriate to effectuate
                  the intent of this Section 15.5 and to avoid unjust or
                  inequitable results as determined in good faith by the Board
                  of Directors.

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

                           (4) "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).

                           (5) "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 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 reductions in the Conversion
         Price, in addition to those required by Sections 15.5(a), (b), (c),
         (d), (e), (f) and (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 reduce the Conversion Price by any amount for any
         period of time if the period is at least twenty (20) days, the
         reduction is irrevocable during the period and the Board of Directors
         shall have made a determination that such reduction would be in the
         best interests of the Company, which determination shall be conclusive
         and described in a Board Resolution. Whenever the Conversion Price is
         reduced pursuant to the preceding sentence, the Company shall mail to
         the holder of each Note at his last address appearing on the Note
         register provided for in Section 2.5 a notice of the reduction at least
         fifteen (15) days prior to the date the reduced Conversion Price takes
         effect, and such notice shall state the reduced Conversion Price and
         the period during which it will be in effect.

                  (j) No adjustment in the Conversion Price shall be required
         unless such adjustment would require an increase or decrease of at
         least 1% in such price; 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 and
         shall be made to the nearest cent or to the nearest one hundredth of a
         share, as the case may be. No adjustment need be made for a change in
         the par value or no par value of the Common Stock.

                  (k) Whenever the Conversion Price is adjusted as herein
         provided, the Company shall promptly file with the Trustee and any
         conversion agent other than the Trustee an Officers' Certificate
         setting forth the Conversion Price after such adjustment and setting
         forth a brief statement of the facts requiring such adjustment.
         Promptly after delivery of such certificate, the Company shall prepare
         a notice of such adjustment of the Conversion Price setting forth the
         adjusted Conversion Price and the date on which each adjustment becomes
         effective and shall mail such notice of such adjustment of the
         Conversion Price to the holder of each Note at his last address
         appearing on the Note register provided for in Section 2.5, within
         twenty (20) days of the effective date of such adjustment. Failure to
         deliver such notice shall not effect the legality or validity of any
         such adjustment.

                  (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


                                      -76-

<PAGE>



         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.

                  (n) In lieu of making any adjustment to the Conversion Price
         pursuant to Section 15.5(e), the Company may elect to reserve an amount
         of cash for distribution to the holders of the Notes 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
         and other items to which such holder is entitled, the full amount of
         cash which such holder would have received if such holder had,
         immediately prior to the Record Date for such distribution of cash,
         converted its Notes into Common Stock, together with any interest
         accrued with respect to such amount, in accordance with this Section
         15.5(n). The Company may make such election by providing an Officers'
         Certificate to the Trustee to such effect on or prior to the payment
         date for any such distribution and depositing with the Trustee on or
         prior to such date an amount of cash equal to the aggregate amount the
         holders of the Notes would have received if such holders had,
         immediately prior to the Record Date for such distribution, converted
         all of the Notes into Common Stock. Any such funds so deposited by the
         Company with the Trustee shall be invested by the Trustee in marketable
         obligations issued or fully guaranteed by the United States government
         with a maturity not more than three (3) months from the date of
         issuance. Upon conversion of Notes by a holder, the holder will be
         entitled to receive, in addition to the Common Stock issuable upon
         conversion, an amount of cash equal to the amount such holder would
         have received if such holder had, immediately prior to the Record Date
         for such distribution, converted its Note into Common Stock, along with
         such holder's pro rata share of any accrued interest earned as a
         consequence of the investment of such funds. Promptly after making an
         election pursuant to this Section 15.5(n), the Company shall give or
         shall cause to be given notice to all Noteholders of such election,
         which notice shall state the amount of cash per $1,000 principal amount
         of Notes such holders shall be entitled to receive (excluding interest)
         upon conversion of the Notes as a consequence of the Company having
         made such election.

         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 change in par value, or
from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination), (ii) any consolidation,


                                      -77-

<PAGE>



merger or combination of the Company with another corporation 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 the properties and assets
of the Company as, or substantially as, an entirety to any other corporation 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
corporation, 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 if such supplemental indenture
is then required to so comply) 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, 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
consolidation, merger, statutory exchange, sale or conveyance (provided that, if
the kind or amount of securities, cash or other property receivable upon such
consolidation, merger, statutory exchange, 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 ("non-electing share"), then for the purposes of this
Section 15.6 the kind and amount of securities, cash or other property
receivable upon such consolidation, merger, statutory exchange, 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. If, in the case of any such reclassification, change, consolidation,
merger, combination, sale or conveyance, the stock or other securities and
assets receivable thereupon by a holder of shares of Common Stock include shares
of stock or other securities and assets of a corporation other than the
successor or purchasing corporation, as the case may be, in such
reclassification, change, consolidation, merger, combination, sale or
conveyance, then such supplemental indenture shall also be executed by such
other corporation and shall contain such additional provisions to protect the
interests of the holders of the Notes as the Board of Directors shall reasonably
consider necessary by reason of the foregoing, including to the extent
practicable the provisions providing for the repurchase rights set forth in
Article XVI herein.

         The Company shall cause notice of the execution of such supplemental
indenture 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, within twenty (20)
days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.



                                      -78-

<PAGE>



         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; 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 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.

         The Company covenants that all shares of Common Stock issued upon
conversion of Notes will 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 further covenants that if at any time the Common Stock
shall be listed on the American 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.

         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 whether any facts exist which may require any
adjustment of the Conversion Price, 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


                                      -79-

<PAGE>



Note; and the Trustee and any other conversion agent make no representations
with respect thereto. Subject to the provisions of Section 8.1, 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.

         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 Price pursuant to Section 15.5); or

                  (b) the Company shall authorize the granting to the holders 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 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
         shareholders of the Company is required, or of the sale or transfer of
         all or substantially all of the assets of the Company; or

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

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of 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 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,


                                      -80-

<PAGE>



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.


                                   ARTICLE XVI

                       REPURCHASE UPON A REPURCHASE EVENT

         Section 16.1 Repurchase Right.

                  (a) If, at any time prior to May 1, 2005 there shall occur a
         Repurchase Event, 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 (in principal amounts of $1,000
         or integral multiples thereof), on the date (the "repurchase date")
         that is forty (40) calendar days after the date of the Company Notice
         (as defined in Section 16.2 below) of such Repurchase Event (or, if
         such 40th day is not a Business Day, the next succeeding Business Day).
         Such repurchase shall be made in cash at a price equal to 100% of the
         principal amount of Notes such holder elects to require the Company to
         repurchase, together with accrued interest, if any, to the repurchase
         date (the "Repurchase Price") (or, at the option of the Company, by
         delivery of Common Stock in accordance with the provisions of Section
         16.3); provided, however, that if such repurchase date is May 1 or
         November 1, then the interest payable on such date shall be paid to the
         holder of record of the Note on the next preceding April 15 or October
         15, respectively. No Notes may be redeemed at the option of holders
         upon a Repurchase Event if there has occurred and is continuing an
         Event of Default, other than a default in the payment of the Repurchase
         Price with respect to such Notes on the repurchase date.

         Section 16.2 Notices; Method of Exercising Repurchase Right, Etc.

                  (a) Unless the Company shall have theretofore called for
         redemption all of the outstanding Notes, on or before the fifteenth
         (15th) calendar day after the occurrence of a Repurchase Event, the
         Company or, at the written request of the Company, the Trustee, shall
         mail to all holders of record of the Notes a notice (the "Company
         Notice") in the form as prepared by the Company of the occurrence of
         the Repurchase Event and of the repurchase right set forth herein
         arising as a result thereof. The Company shall also deliver a copy of
         such notice of a repurchase right to the Trustee and cause a copy of
         such notice of a repurchase right, or a summary of the information
         contained therein, to be


                                      -81-

<PAGE>



         published once in a newspaper of general circulation in The City of New
         York. The Company Notice shall contain the following information:

                           (1) the repurchase date,

                           (2) the date by which the repurchase right must
                  be exercised,

                           (3) the last date by which the election to
                  require repurchase, if submitted, must be revoked;

                           (4) the Repurchase Price and whether the Repurchase
                  Price shall be payable in cash or Common Stock and, if payable
                  in Common Stock, the method of calculating the amount of the
                  Common Stock to be delivered upon the repurchase as provided
                  in Section 16.3(a);

                           (5) a description of the procedure which a holder
                  must follow to exercise a repurchase right, and

                           (6) the Conversion Price then in effect, the date on
                  which the right to convert the principal amount of the Notes
                  to be repurchased will terminate and the place or places where
                  Notes may be surrendered for conversion.

                  No failure of the Company to give the foregoing notices or
         defect therein shall limit any holder's right to exercise a repurchase
         right or affect the validity of the proceedings for the repurchase of
         Notes.

                  If any of the foregoing provisions are inconsistent with
         applicable law, such law shall govern.

                  (b) To exercise a repurchase right, a holder shall deliver to
         the Trustee on or before the thirty-fifth (35th) day after the Company
         Notice was delivered (i) written notice to the Company (or agent
         designated by the Company for such purpose) of the holder's exercise of
         such right, which notice shall set forth the name of the holder, the
         principal amount of the Notes to be repurchased, a statement that an
         election to exercise the repurchase right is being made thereby, and,
         in the event that the Repurchase Price shall be paid in shares of
         Common Stock, the name or names (with addresses) in which the
         certificate or certificates for shares of Common Stock shall be issued,
         and (ii) the Notes with respect to which the repurchase right is being
         exercised, duly endorsed for transfer to the Company. Election of
         repurchase by a holder shall be revocable at any time prior to, but
         excluding, the repurchase date, by delivering written notice to that
         effect to the Trustee prior to the close of business on the Business
         Day prior to the repurchase date.



                                      -82-

<PAGE>



                  (c) If the Company fails to repurchase on the repurchase date
         any Notes (or portions thereof) as to which the repurchase right has
         been properly exercised, then the principal of such Notes shall, until
         paid, bear interest to the extent permitted by applicable law from the
         repurchase date at the rate borne by the Note and each such Note shall
         be convertible into Common Stock in accordance with this Indenture
         (without giving effect to Section 16.2(b)) until the principal of such
         Note shall have been paid or duly provided for.

                  (d) Any Note which is to be repurchased only in part shall be
         surrendered to the Trustee duly endorsed for transfer to the Company
         and accompanied by appropriate evidence of genuineness and authority
         satisfactory to the Company and the Trustee duly executed by, the
         holder thereof (or his attorney duly authorized in writing), and the
         Company shall execute, and the Trustee shall authenticate and deliver
         to the holder of such Note without service charge, a new Note or Notes,
         containing identical terms and conditions, of any authorized
         denomination as requested by such holder in aggregate principal amount
         equal to and in exchange for the unrepurchased portion of the principal
         of the Note so surrendered.

                  (e) On or prior to the repurchase date, the Company shall
         deposit with the Trustee or with a paying agent (or, if the Company is
         acting as its own paying agent, segregate and hold in trust as provided
         in Section 5.4) the Repurchase Price in cash for payment to the holder
         on the repurchase date; provided that if payment is to be made in cash,
         such cash 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; provided further that if the Repurchase
         Price is to be paid in shares of Common Stock, such shares of Common
         Stock are to be paid as promptly after the repurchase date as
         practicable.

                  (f) Any issuance of shares of Common Stock in respect of the
         Repurchase Price shall be deemed to have been effected immediately
         prior to the close of business on the repurchase date and the person or
         persons in whose name or names any certificate or certificates for
         shares of Common Stock shall be issuable upon such repurchase shall be
         deemed to have become on the repurchase date the holder or holders of
         record of the shares represented thereby; provided, however, that any
         surrender for repurchase on a date when the stock transfer books of the
         Company shall be closed shall constitute the person or persons in whose
         name or names the certificate or certificates for such shares are to be
         issued as the record holder or holders thereof for all purposes at the
         opening of business on the next succeeding day on which such stock
         transfer books are open. No payment or adjustment shall be made for
         dividends or distributions on any Common Stock issued upon repurchase
         of any Security declared prior to the repurchase date.

                  (g) No fractions of shares shall be issued upon repurchase of
         Notes. If more than one Note shall be repurchased from the same holder
         and the Repurchase Price shall


                                      -83-

<PAGE>



         be payable in shares of Common Stock, the number of full shares which
         shall be issuable upon such repurchase shall be computed on the basis
         of the aggregate principal amount of the Notes so repurchased. Instead
         of any fractional share of Common Stock which would otherwise be
         issuable on the repurchase of any Note or Notes, the Company will
         deliver to the applicable holder its check for the current market value
         of such fractional share. The current market value of a fraction of a
         share is determined by multiplying the current market price of a full
         share by the fraction, and rounding the result to the nearest cent. For
         purposes of this Section, the current market price of a share of Common
         Stock is the Closing Price of the Common Stock on the Trading Day
         immediately preceding the repurchase date.

                  (h) Any issuance and delivery of certificates for shares of
         Common Stock on repurchase of Notes shall be made without charge to the
         holder of Notes being repurchased for such certificates or for any tax
         or duty in respect of the issuance or delivery of such certificates or
         the securities represented thereby; provided, however, that the Company
         shall not be required to pay any tax or duty which may be payable in
         respect of (i) income of the holder or (ii) any transfer involved in
         the issuance or delivery of certificates for shares of Common Stock in
         a name other than that of the holder of the Notes being repurchased,
         and no such issuance or delivery shall be made unless and until the
         person requesting such issuance or delivery has paid to the Company the
         amount of any such tax or duty or has established, to the satisfaction
         of the Company, that such tax or duty has been paid.

                  (i) All Notes delivered for repurchase shall be delivered to
         the Trustee to be canceled in accordance with the provisions of Section
         2.8.

         Section 16.3 Conditions to the Company's Election to Pay the Repurchase
Price in Common Stock.

         The Company may elect to pay the Repurchase Price by delivery of shares
of Common Stock pursuant to Section 16.1 if and only if the following conditions
shall have been satisfied:

         (a) The shares of Common Stock deliverable in payment of the Repurchase
Price shall have a fair market value as of the repurchase date of not less than
the Repurchase Price. For purposes of Section 16.1 and this Section 16.3, the
fair market value of shares of Common Stock shall be determined by the Company
and shall be equal to 95% of the average of the Closing Prices of the Common
Stock for the five consecutive Trading Days immediately preceding and including
the third Trading Day prior to the repurchase date;

         (b) The Repurchase Price shall be paid only in cash in the event any
shares of Common Stock to be issued upon repurchase of Notes hereunder (i)
require registration under any federal securities law before such shares may be
freely transferable without being subject to any transfer restrictions under
the Securities Act upon repurchase and if such registration is not


                                      -84-

<PAGE>



completed or does not become effective prior to the repurchase date, and/or (ii)
require registration with or approval of any governmental authority under any
state law or any other federal law before such shares may be validly issued or
delivered upon repurchase and if such registration is not completed or does not
become effective or such approval is not obtained prior to the repurchase date;

         (c) Payment of the Repurchase Price may not be made in Common Stock
unless such stock is, or shall have been, listed on a national securities
exchange or approved for quotation on the Nasdaq National Market, in either
case, prior to the repurchase date; and

         (d) All shares of Common Stock which may be issued upon repurchase of
the Notes will be issued out of the Company's authorized but unissued Common
Stock and, will upon issue, be duly and validly issued and fully paid and
non-assessable and free of any preemptive rights.

         If all of the conditions set forth in this Section 16.3 are not
satisfied in accordance with the terms thereof, the Repurchase Price shall be
paid by the Company only in cash.

         Section 16.4 Certain Definitions. For purposes of this Article XVI:

                  (a) the term "beneficial owner" shall be determined in
         accordance with Rule 13d-3 and 13d-5, as in effect on the date of the
         original execution of this Indenture, promulgated by the Securities and
         Exchange Commission pursuant to the Exchange Act;

                  (b) the term "person" or "group" shall include any syndicate
         or group which would be deemed to be a "person" under Section 13(d) and
         14(d) of the Exchange Act as in effect on the date of the original
         execution of this Indenture; and

                  (c) the term "Continuing Director" means at any date a member
         of the Company's Board of Directors (i) who was a member of such board
         on April 24, 1998 or (ii) who was nominated or elected by at least a
         majority of the directors who were Continuing Directors at the time of
         such nomination or election or whose election to the Company's Board of
         Directors was recommended or endorsed by at least a majority of the
         directors who were Continuing Directors at the time of such nomination
         or election or such lesser number comprising a majority of a nominating
         committee if authority for such nominations or elections has been
         delegated to a nominating committee whose authority and composition
         have been approved by at least a majority of the directors who were
         continuing directors at the time such committee was formed. (Under this
         definition, if the Board of Directors of the Company as of the date of
         this Indenture were to approve a new director or directors and then
         resign, no Change in Control would occur even though the current Board
         of Directors would thereafter cease to be in office).

<PAGE>



                  (d) the term "Repurchase Event" means a Change in Control or a
         Termination of Trading.

                  (e) a "Change in Control" shall be deemed to have occurred
         when (i) any "person" or "group" (as such terms are used in Sections
         13(d) and 14(d) of the Exchange Act) is or becomes the "beneficial
         owner" (as defined in Rules 13-d3 and 13-d5 under the Exchange Act) of
         shares representing more than 50% of the combined voting power of the
         then outstanding securities entitled to vote generally in elections of
         directors of the Company (the "Voting Stock"); (ii) approval by
         stockholders of the Company of any plan or proposal for the
         liquidation, dissolution or winding up of the Company; (iii) the
         Company (A) consolidates with or merges into any other corporation or
         any other corporation merges into the Company, and in the case of any
         such transaction, the outstanding Common Stock of the Company is
         changed or exchanged into other assets or securities as a result,
         unless the stockholders of the Company immediately before such
         transaction own, directly or indirectly immediately following such
         transaction, at least 51% of the combined voting power of the
         outstanding voting securities of the corporation resulting from such
         transaction in substantially the same proportion as their ownership of
         the Voting Stock immediately before such transaction, or (B) conveys,
         transfers or leases all or substantially all of its assets to any
         person; or (iv) any time Continuing Directors do not constitute a
         majority of the Board of Directors of the Company (or, if applicable, a
         successor corporation to the Company); provided that a Change in
         Control shall not be deemed to have occurred if either (x) the Closing
         Price (as defined in Section 15.5(h)(1) hereof) of the Common Stock for
         any five (5) Trading Days during the ten (10) Trading Days immediately
         preceding the Change in Control is at least equal to 105% of the
         Conversion Price in effect on the date on which the Change in Control
         occurs or (y) in the case of a merger or consolidation otherwise
         constituting a Change in Control, at least 90% of the consideration
         (excluding cash payments for fractional shares) in such merger or
         consolidation constituting the Change in Control consists of common
         stock traded on a United States national securities exchange or quoted
         on the Nasdaq National Market (or which will be so traded or quoted
         when issued or exchanged in connection with such Change in Control) and
         as a result of such transaction or transactions such Notes become
         convertible solely into such common stock.

                  (f) a "Termination of Trading" shall have occurred if the
         Common Stock (or other common stock into which the Notes are then
         convertible) is neither listed for trading on a United States national
         securities exchange nor approved for trading on an established
         automated over-the-counter trading market in the United States;
         provided that if such occurrence is the result of the primary exchange
         or market on which such Common Stock was so listed or traded generally
         not being available for listing or trading securities, a "Termination
         of Trading" shall not have occurred until the Common Stock shall have
         continued not to be so listed or not to be so approved for trading for
         more than thirty (30) days.

the original issuance thereof and transfers and exchanges of Notes hereunder,
including under Sections 2.4, 2.5, 2.6, 2.7 and 3.3, 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
the Trustee by an authenticating agent shall be deemed to satisfy any
requirement hereunder or in the Notes for the Trustee's certificate of
authentication. Such authenticating agent shall at all times be a person
eligible to serve as trustee hereunder pursuant to Section 8.9.

         Any corporation into which any authenticating agent may be merged or

Section, without the execution or filing of any paper or any further act on the
part of the parties hereto or the authenticating agent or such successor
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 promptly appoint a successor authenticating agent (which may be
the Trustee), shall give written notice of such appointment to the Company and
shall mail notice of such appointment 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 for such
pre-approved payments, subject to Section 8.6.


                                      -89-

shall be applicable to any authenticating agent.

         Section 17.12 Execution in Counterparts. This Indenture may be executed

counterparts shall together constitute but one and the same instrument.

         The First National Bank of Chicago hereby accepts the trusts in this
Indenture declared and provided, upon the terms and conditions hereinabove set
forth.
