                                       10



Custodian to cause, in accordance with the standing instructions and 
procedures existing between the Depositary and the Securities Custodian, the 
aggregate principal amount of Securities represented by the Global Security 
to be increased accordingly.  If no Global Securities are then outstanding, 
the Company shall issue and the Trustee shall authenticate a new Global 
Security in the appropriate principal amount.

     (c)  TRANSFER AND EXCHANGE OF GLOBAL SECURITIES.  The transfer and 
exchange of Global Securities or beneficial interests therein shall be 
effected through the Depositary, in accordance with this Indenture and the 
procedures of the Depositary therefor. 

     (d)  TRANSFER OF A BENEFICIAL INTEREST IN A GLOBAL SECURITY FOR A
DEFINITIVE SECURITY.

          (i)  Any Person having a beneficial interest in a Global Security may
     upon request exchange such beneficial interest for a Definitive Security. 
     Upon receipt by the Registrar of written instructions or such other form of
     instructions as is customary for the Depositary from the Depositary or its
     nominee on behalf of any Person having a beneficial interest in a Global
     Security, and, if such beneficial interest is being transferred to the
     Person designated by the Depositary as being the beneficial owner, a
     certification from such person to that effect (in substantially the form
     set forth on the reverse of the Security)(all of which may be submitted by
     facsimile), then the Registrar or the Securities Custodian, at the
     direction of the Trustee, will cause, in accordance with the standing
     instructions and procedures existing between the Depositary and the
     Securities Custodian, the aggregate principal amount of the Global Security
     to be reduced and, following such reduction, the Company will execute and,
     upon receipt of an authentication order in the form of an Officers'
     Certificate, the Trustee or the Trustee's authenticating agent will
     authenticate and deliver to the transferee a Definitive Security.

          (ii)  Definitive Securities issued in exchange for a beneficial
     interest in a Global Security pursuant to this Section 2.6(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 Registrar.  The Registrar
     shall deliver such Definitive Securities to the persons in whose names such
     Securities are so registered.

     (e)  RESTRICTIONS ON TRANSFER AND EXCHANGE OF GLOBAL SECURITIES. 
Notwithstanding any other provisions of this Indenture (other than the 
provisions set forth in subsection (f) of this Section 2.6), a Global 
Security may not be transferred as a whole 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.

                                       11



     (f)  AUTHENTICATION OF DEFINITIVE SECURITIES IN ABSENCE OF DEPOSITARY.  If
at any time:

          (i)  the Depositary for the Securities notifies the Company that the
     Depositary is unwilling or unable to continue as Depositary for the Global
     Securities and a successor Depositary for the Global Securities is not
     appointed by the Company within 90 days after delivery of such notice; or

          (ii)  the Company, in its sole discretion, notifies the Trustee and
     the Registrar in writing that it elects to cause the issuance of Definitive
     Securities under this Indenture,

then the Company will execute, and the Trustee, upon receipt of an Officers' 
Certificate requesting the authentication and delivery of Definitive 
Securities, will, or its authenticating agent will, authenticate and deliver 
Definitive Securities, in an aggregate principal amount equal to the 
principal amount of the Global Securities, in exchange for such Global 
Securities.

     (g)  CANCELLATION AND/OR ADJUSTMENT OF GLOBAL SECURITY.  At such time as 
all beneficial interests in a Global Security have either been exchanged for 
Definitive Securities, redeemed, repurchased or cancelled, such Global 
Security shall be returned to or retained and cancelled by the Registrar.  At 
any time prior to such cancellation, if any beneficial interest in a Global 
Security is exchanged for Definitive Securities, redeemed, repurchased or 
cancelled, the principal amount of Securities represented by such Global 
Security shall be reduced and an endorsement shall be made on such Global 
Security, by the Registrar or the Securities Custodian, at the direction of 
the Registrar, to reflect such reduction.

     (h)  OBLIGATIONS WITH RESPECT TO TRANSFERS AND EXCHANGES.  At the option 
of the Holder, Securities may be exchanged for other Securities of any 
authorized denomination or denominations, of a like aggregate Principal 
Amount, upon surrender of the Securities to be exchanged, together with a 
written instrument of transfer satisfactory to the Registrar duly executed by 
the Securityholder or such Securityholder's attorney duly authorized in 
writing, at such office or agency.  Whenever any Securities are so 
surrendered for exchange, the Company shall execute, and the Trustee shall 
authenticate and deliver, the Securities which the Holder making the exchange 
is entitled to receive.

     The Company shall not be required to make, and the Registrar need not 
register, transfers or exchanges of (a) Definitive Securities selected for 
redemption (except, in the case of Securities to be redeemed in part, the 
portion thereof not to be redeemed), (b) any Securities in respect of which a 
Purchase Notice or a Change in Control Purchase Notice has been given and not 
withdrawn by the Holder thereof in accordance with the terms of this 
Indenture (except, in the case of Securities to be purchased in part, the 
portion thereof not to be purchased) or (c) any Securities for a period of 15 
days before the mailing of a notice of redemption.

                                       12



     Successive registrations and registrations of transfers and exchanges as
aforesaid may be made from time to time as desired, and each such registration
shall be noted on the register for the Securities.

     Any Registrar appointed pursuant to Section 2.03 hereof shall provide to
the Trustee such information as the Trustee may reasonably require in connection
with the delivery by such Registrar of Securities upon transfer or exchange of
Securities.

     No Registrar shall be required to make registrations of transfer or 
exchange of Securities during any periods designated in the text of the 
Securities or in this Indenture as periods during which such registration of 
transfers and exchanges need not be made.

     SECTION 2.07.  REPLACEMENT SECURITIES.  If (a) any mutilated Security is 
surrendered to the Company or the Trustee, or (b) the Company and the Trustee 
receive evidence to their satisfaction of the destruction, loss or theft of 
any Security, and there is delivered to the Company and the Trustee such 
security or indemnity as may be required by them to save each of them 
harmless, then, in the absence of notice to the Company or the Trustee that 
such Security has been acquired by a BONA FIDE purchaser, the Company shall 
execute, and upon its written request the Trustee shall authenticate and 
deliver, in exchange for any such mutilated Security or in lieu of any such 
destroyed, lost or stolen Security, a new Security of like tenor and 
Principal Amount, bearing a number not contemporaneously outstanding.

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

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

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

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

                                       13




     SECTION 2.08.  OUTSTANDING SECURITIES; DETERMINATIONS OF HOLDERS' 
ACTION. Securities outstanding at any time are all the Securities 
authenticated by the Trustee (including any Security represented by a Global 
Security) except for those cancelled by it, those delivered to it for 
cancellation, mutilated, destroyed, lost or stolen Securities for which the 
Trustee has authenticated and delivered a new Security in lieu therefor 
pursuant to Section 2.07, those paid pursuant to Section 2.07, those 
reductions in the interest in a Global Security effected by the Registrar 
hereunder and those described in this Section 2.08 as not outstanding.  A 
Security does not cease to be outstanding because the Company or an Affiliate 
thereof holds the Security; PROVIDED, HOWEVER, that in determining whether 
the Holders of the requisite Principal Amount of Securities have given or 
concurred in any request, demand, authorization, direction, notice, consent 
or waiver hereunder, Securities owned by the Company or any other obligor 
upon the Securities or any Affiliate of the Company or such other obligor 
shall be disregarded and deemed not to be outstanding, except that, in 
determining whether the Trustee shall be protected in relying upon any such 
request, demand, authorization, direction, notice, consent or waiver, only 
Securities which the Trustee actually knows to be so owned shall be so 
disregarded.  Subject to the foregoing, only Securities outstanding at the 
time of such determination shall be considered in any such determination 
(including, without limitation, determinations pursuant to Articles 6 and 9).

     If a Security is replaced pursuant to Section 2.07, it ceases to be 
outstanding unless the Trustee receives proof satisfactory to it that the 
replaced Security is held by a bona fide purchaser.

     If the Paying Agent holds, in accordance with this Indenture, on a 
Redemption Date, or on the Business Day following a Purchase Date or a Change 
in Control Purchase Date, or on Stated Maturity, money or, if permitted by 
the terms hereof including, without limitation, Section 3.08, securities 
sufficient to pay the Securities payable on that date, then on and after that 
date such Securities shall cease to be outstanding and Original Issue 
Discount and interest, if any, on such Securities shall cease to accrue and 
all other rights of the Holder shall terminate (other than the right to 
receive the applicable Redemption Price, Purchase Price or Change in Control 
Purchase Price, as the case may be, upon delivery of the Security in 
accordance with the terms of this Indenture); PROVIDED, that if such 
Securities are to be redeemed, notice of such redemption has been duly given 
pursuant to this Indenture or provision therefor satisfactory to the Trustee 
has been made.

     If a Security is converted in accordance with Article 10, then from and 
after the Conversion Date such Security shall cease to be outstanding and 
Original Issue Discount and interest, if any, shall cease to accrue on such 
Security.

     SECTION 2.09.  TEMPORARY SECURITIES.  Pending the preparation of definitive
Securities, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other

                                       14


variations as the Officers executing such Securities may determine, as 
conclusively evidenced by their execution of such Securities.

     If temporary Securities are issued, the Company will cause definitive 
Securities to be prepared without unreasonable delay.  After the preparation 
of definitive Securities, the temporary Securities shall be exchangeable for 
definitive Securities upon surrender of the temporary Securities at the 
office or agency of the Company designated for such purpose pursuant to 
Section 2.03 or 4.05, without charge to the Holder.  Upon surrender for 
cancellation of any one or more temporary Securities the Company shall 
execute and the Trustee shall authenticate and deliver in exchange therefor a 
like Principal Amount of definitive Securities of authorized denominations.  
Until so exchanged the temporary Securities shall in all respects be entitled 
to the same benefits under this Indenture as definitive Securities.

     SECTION 2.10. CANCELLATION.  All Securities surrendered for payment, 
redemption or purchase by the Company pursuant to Article 3, conversion 
pursuant to Article 10, registration of transfer or exchange shall, if 
surrendered to any person other than the Trustee, be delivered to the Trustee 
and shall be promptly cancelled by it.  The Company may at any time deliver 
to the Trustee for cancellation any Securities previously authenticated and 
delivered hereunder which the Company may have acquired in any manner 
whatsoever, and all Securities so delivered shall be promptly cancelled by 
the Trustee.  The Company may not issue new Securities to replace Securities 
it has paid or delivered to the Trustee for cancellation or that any Holder 
has converted pursuant to Article 10.  No Securities shall be authenticated 
in lieu of or in exchange for any Securities cancelled as provided in this 
Section, except as expressly permitted by this Indenture.  All cancelled 
Securities held by the Trustee shall be delivered to the Company.

     SECTION 2.11.  CUSIP NUMBERS.  The Company in issuing the Securities may 
use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall 
use "CUSIP" numbers in notices of redemption as a convenience to Holders; 
PROVIDED that any such notice may state that no representation is made as to 
the correctness of such numbers either as printed on the Securities or as 
contained in any notice of a redemption and that reliance may be placed only 
on the other identification numbers printed on the Securities, and any such 
redemption shall not be affected by any defect in or omission of such 
numbers.  The Company will promptly notify the Trustee of any change in the 
CUSIP numbers.

                                       15


                                     ARTICLE 3

                               REDEMPTION AND PURCHASES


     SECTION 3.01.  RIGHT TO REDEEM; NOTICES TO TRUSTEE.  The Company, at its 
option, may redeem the Securities for cash in accordance with the provisions 
set forth in paragraphs 5 and 7 of the Securities.  If the Company elects to 
redeem Securities pursuant to paragraph 5 of the Securities, it shall notify 
the Trustee in writing of the Redemption Date, the Principal Amount of 
Securities to be redeemed and the Redemption Price.

     The Company shall give the notice to the Trustee provided for in this 
Section 3.01 at least 45 days but not more than 60 days before the Redemption 
Date (unless a shorter notice shall be satisfactory to the Trustee).  If 
fewer than all the Securities are to be redeemed, the record date relating to 
such redemption shall be selected by the Company and given to the Trustee, 
which record date shall not be less than ten days after the date of notice to 
the Trustee.

     SECTION 3.02.  SELECTION OF SECURITIES TO BE REDEEMED.  If less than all 
the Securities are to be redeemed, the Trustee shall select the Securities to 
be redeemed by lot or by any other method the Trustee considers fair and 
appropriate (so long as such method is not prohibited by the rules of any 
stock exchange on which the Securities are then listed).  The Trustee shall 
make the selection at least 30 but not more than 60 days before the 
Redemption Date from outstanding Securities not previously called for 
redemption.  The Trustee may select for redemption portions of the Principal 
Amount of Securities that have denominations larger than $1,000.  Securities 
and portions of them the Trustee selects shall be in Principal Amounts of 
$1,000 or an integral multiple of $1,000.  Provisions of this Indenture that 
apply to Securities called for redemption also apply to portions of 
Securities called for redemption.  The Trustee shall notify the Company 
promptly of the Securities or portions of Securities to be redeemed.

     If any Security selected for partial redemption is thereafter 
surrendered for conversion in part before termination of the conversion right 
with respect to the portion of the Security so selected, the converted 
portion of such Security shall be deemed (so far as may be), solely for 
purposes of determining the aggregate Principal Amount of Securities to be 
redeemed by the Company, to be the portion selected for redemption.  
Securities that have been converted during a selection of Securities to be 
redeemed may be treated by the Trustee as outstanding for the purpose of such 
selection.  Nothing in this Section 3.02 shall affect the right of any Holder 
to convert any Security pursuant to Article 10 before the termination of the 
conversion right with respect thereto.

   SECTION 3.03.  NOTICE OF REDEMPTION.  At least 30 days but not more than 
60 days before a Redemption Date, the Trustee, in the name and at the expense 
of the Company, shall cause notice of redemption to be mailed, first-class 
postage prepaid, to each Holder of Securities to be redeemed


                                       16


at his address as it appears on the list of Securityholders maintained 
pursuant to Section 2.05.  At the Company's written request, the Trustee 
shall, in the name and at the expense of the Company, cause a similar notice 
to be published at least once in an Authorized Newspaper in each place of 
payment. 

   The notice shall identify the Securities to be redeemed and shall state:

          (1) the Redemption Date (upon which the Redemption Price shall be
     paid);

          (2) the Redemption Price;

          (3) the Conversion Rate;

          (4) the name and address of the Paying Agent and Conversion Agent and
     of the office or agency referred to in Section 4.05;

          (5) that Securities called for redemption may be converted at any time
     before the close of business on the Redemption Date;

          (6) that Holders who want to convert Securities must satisfy the
     requirements set forth in paragraph 8 of the Securities;

          (7) that Securities called for redemption must be surrendered to the
     Paying Agent or at the office or agency referred to in Section 4.05 to
     collect the Redemption Price;

          (8) the CUSIP number of the Securities;

          (9) if fewer than all the outstanding Securities are to be redeemed,
     the certificate numbers and Principal Amounts of the particular Securities
     to be redeemed; and

          (10) that, unless the Company defaults in payment of the Redemption
     Price, Original Issue Discount on Securities called for redemption and
     interest, if any, will cease to accrue on and after the Redemption Date.

     At the Company's written request, the Trustee shall give the notice of 
redemption in the Company's name and at the Company's expense, provided that 
the Company makes such request at least three Business Days prior to such 
notice of redemption.

     SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.  Once notice of redemption
is given, Securities called for redemption become due and payable on the
Redemption Date stated in the notice and at the Redemption Price therefor except
for Securities that are converted in accordance

                                       17


with the terms of this Indenture.  Upon the later of the Redemption Date and 
the date such Securities are surrendered to the Paying Agent or at the office 
or agency referred to in Section 4.05, such Securities called for redemption 
shall be paid at the Redemption Price therefor.

     SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.  Prior to or on the 
Redemption Date, the Company shall deposit with the Paying Agent (or if the 
Company or a Subsidiary or an Affiliate of either of them is the Paying 
Agent, shall segregate and hold in trust) money sufficient to pay the 
Redemption Price of all Securities to be redeemed on that date other than 
Securities or portions of Securities called for redemption which prior 
thereto have been delivered by the Company to the Trustee for cancellation.  
The Paying Agent shall as promptly as practicable return to the Company any 
money, with interest, if any, thereon (subject to the provisions of Section 
7.01(f)), not required for that purpose because of conversion of Securities 
pursuant to Article 10.  If such money is then held by the Company or a 
Subsidiary or an Affiliate of the Company in trust and is not required for 
such purpose it shall be discharged from such trust.

     SECTION 3.06.  SECURITIES REDEEMED IN PART.  Upon surrender of a 
Security that is redeemed in part, the Company shall execute, and the Trustee 
shall authenticate and deliver to the Holder, a new Security in an authorized 
denomination equal in Principal Amount to the unredeemed portion of the 
Security surrendered.

     SECTION 3.07.  CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION.  In 
connection with any redemption of Securities, the Company may arrange, in 
lieu of redemption, for the purchase and conversion of any Securities called 
for redemption by an agreement with one or more investment bankers or other 
purchasers to purchase all or a portion of such Securities by paying to the 
Trustee in trust for the Securityholders whose Securities are to be so 
purchased, on or before the close of business on the Redemption Date, an 
amount that, together with any amounts deposited with the Trustee by the 
Company for redemption of such Securities, is not less than the Redemption 
Price, together with interest, if any, accrued to the Redemption Date, of 
such Securities. Notwithstanding anything to the contrary contained in this 
Article 3, the obligation of the Company to pay the Redemption Price of such 
Securities, including all accrued interest, if any, shall be deemed to be 
satisfied and discharged to the extent such amount is so paid by such 
purchasers, but no such agreement shall relieve the Company of its obligation 
to pay such Redemption Price and interest, if any.  If such an agreement is 
entered into, any Securities not duly surrendered for conversion by the 
Holders thereof may, at the option of the Company, be deemed, to the fullest 
extent permitted by law, acquired by such purchasers from such Holders and 
(notwithstanding anything to the contrary contained in Article 10) 
surrendered by such purchasers for conversion, all as of immediately prior to 
the close of business on the Redemption Date, subject to payment of the above 
amount as aforesaid.  The Trustee shall hold and pay to the Holders whose 
Securities are selected for redemption any such amount paid to it for 
purchase and conversion in the same manner as it would moneys deposited with 
it by the Company for the redemption of Securities.  Without the Trustee's 
prior written consent, no arrangement between the Company and such purchasers 
for the 

                                       18


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

     SECTION 3.08.  PURCHASE OF SECURITIES AT THE OPTION OF THE HOLDER.

     (a) GENERAL.  Securities shall be purchased by the Company pursuant to
paragraph 6 of the Securities as of [            ] and [                ] 
(each, a "PURCHASE DATE"), at the purchase price specified therein (each, a 
"PURCHASE PRICE"), at the option of the Holder thereof, upon:

          (1) delivery to the Paying Agent or to the office or agency referred
     to in Section 4.05 by the Holder of a written notice of purchase (a
     "PURCHASE NOTICE") at any time from the opening of business on the date
     that is 20 Business Days prior to a Purchase Date until the close of
     business on such Purchase Date stating:

               (A) the certificate number of the Security that the Holder will
          deliver to be purchased;

               (B) the portion of the Principal Amount of the Security which the
          Holder will deliver to be purchased, which portion must be $1,000 or
          an integral multiple thereof;

               (C) that such Security shall be purchased on the Purchase Date
          pursuant to the terms and conditions specified in this Indenture and
          in paragraph 6 of the Securities; and

               (D) if the Company elects pursuant to Section 3.08(b) to pay the
          Purchase Price on such Purchase Date, in whole or in part, in shares
          of Common Stock, but such portion of the Purchase Price to be paid in
          Common Stock is ultimately to be paid in cash because any condition in
          Section 3.08(d) is not satisfied, such Holder elects (i) to withdraw
          such Purchase Notice as to some or all of the Securities to which it
          relates (stating the Principal Amount and certificate numbers of the
          Securities as to which such withdrawal shall relate), or (ii) to
          receive cash in respect of the Purchase Price for all Securities
          subject to such Purchase Notice; and

          (2) delivery of such Security prior to, on or after the Purchase Date
     (together with all necessary endorsements) to the Paying Agent at the
     offices of the Paying Agent or to the office or agency referred to in
     Section 4.05, such delivery being a condition to receipt by the 


                                       19



     Holder of the Purchase Price therefor; PROVIDED, HOWEVER, that such
     Purchase Price shall be so paid pursuant to this Section 3.08 only if the
     Security so delivered conforms in all respects to the description thereof
     in the related Purchase Notice.

     If a Holder, in such Holder's Purchase Notice and in any written notice of
withdrawal delivered by such Holder pursuant to the terms of Section 3.10, fails
to indicate such Holder's choice with respect to the election set forth in
clause (D) of Section 3.08(a)(1) above, such Holder shall be deemed to have
elected to receive cash in respect of the Purchase Price otherwise payable in
Common Stock.

     The Company shall purchase from the Holder thereof, pursuant to this
Section 3.08, a portion of a Security if the Principal Amount of such portion is
$1,000 or an integral multiple of $1,000.  Provisions of this Indenture that
apply to the purchase of all of a Security also apply to the purchase of such
portion of such Security.

     Any purchase by the Company contemplated pursuant to the provisions hereof
shall be consummated by the delivery of the consideration to be received by the
Holder promptly following the later of the Purchase Date and the time of
delivery of the Security.

     Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent or the office or agency referred to in Section 4.05 the
Purchase Notice contemplated by this Section 3.08(a) shall have the right to
withdraw at any time prior to the close of business on the Purchase Date such
Purchase Notice by delivery of a written notice of withdrawal to the Paying
Agent or such office or agency in accordance with Section 3.10.

     The Paying Agent shall promptly notify the Company of the receipt by it of
any Purchase Notice or written notice of withdrawal thereof.

     (b)  COMPANY'S RIGHT TO ELECT MANNER OF PAYMENT OF PURCHASE PRICE.  The
Securities to be purchased pursuant to Section 3.08(a) may be paid for, at the
election of the Company, in cash or Common Stock, or in any combination of cash
and Common Stock, subject to the conditions set forth in this Section 3.08.  The
Company shall designate, in the notice from the Company delivered pursuant to
Section 3.08(e), whether the Company will purchase the Securities for cash or
Common Stock, and, if a combination thereof, the percentages of the Purchase
Price of Securities in respect of which it will pay in cash or Common Stock;
PROVIDED that the Company will pay cash for fractional interests in Common
Stock.  For purposes of determining the existence of potential fractional
interests, all Securities subject to purchase by the Company held by a Holder
shall be considered together (no matter how many separate certificates are to be
presented).  Each Holder whose Securities are purchased pursuant to this Section
3.08 shall receive the same percentage of cash or Common Stock in payment of the
Purchase Price for such Securities, except (i) as provided in Section 3.08(d)
with regard to the payment of cash in lieu of fractional shares of Common Stock


                                       20



and (ii) in the event that the Company is unable to purchase the Securities 
of a Holder or Holders for Common Stock because any necessary qualifications 
or registrations of the Common Stock under applicable state securities laws 
cannot be obtained, the Company may purchase the Securities of such Holder or 
Holders for cash.  The Company may not change its election with respect to 
the consideration (or components or percentages of components thereof) to be 
paid once the Company has given notice thereof to Securityholders except 
pursuant to this Section 3.08(b) or Section 3.08(d).

     At least five Business Days before the Company Notice Date (as defined
below), the Company shall deliver an Officers' Certificate to the Trustee
specifying:

          (i) the manner of payment selected by the Company;

          (ii) the information required by Section 3.08(e);

          (iii) that the conditions to such manner of payment set forth in
          Section 3.08(d) have or will be complied with; and

          (iv) whether the Company desires the Trustee to give the notice
          required by Section 3.08(e).

     (c)  PURCHASE WITH CASH.  On each Purchase Date, at the option of the
Company, the Principal Amount of the Securities in respect of which a Purchase
Notice pursuant to Section 3.08(a) has been given, or a specified percentage
thereof, may be purchased by the Company with cash equal to the aggregate
Purchase Price of such Securities.

     (d)  PAYMENT BY COMMON STOCK.  On each Purchase Date, at the option of the
Company, the Principal Amount of the Securities in respect of which a Purchase
Notice pursuant to Section 3.08(a) has been given, or a specified percentage
thereof, may be purchased by the Company by the issuance of a number of shares
of Common Stock equal to the quotient obtained by dividing (i) the amount of
cash to which the Securityholders would have been entitled had the Company
elected to pay all or such specified percentage, as the case may be, of the
Purchase Price of such Securities in cash by (ii) the Market Price (as defined
below) of a share of Common Stock, subject to the next succeeding paragraph.

     The Company will not issue a fractional share of Common Stock in payment of
the Purchase Price.  Instead the Company will pay cash for the current market
value of the fractional share.  The current market value of a fraction of a
share shall be determined by multiplying the Market Price by such fraction and
rounding the product to the nearest whole cent, with one-half cent being rounded
upward.  It is understood that if a Holder elects to have more than one Security
purchased, the 


                                       21



number of shares of Common Stock shall be based on the aggregate amount of 
Securities to be purchased.

     The Company's right to exercise its election to purchase the Securities
pursuant to this Section through the issuance of shares of Common Stock shall be
conditioned upon:

          (i) the Company's not having given notice of an election to pay
          entirely in cash and its giving of timely notice of election to
          purchase all or a specified percentage of the Securities with Common
          Stock as provided herein;

          (ii) the registration of the shares of Common Stock to be issued in
          respect of the payment of the Purchase Price under the Securities Act
          of 1933, as amended (the "SECURITIES ACT") and the Securities Exchange
          Act of 1934, as amended (the "EXCHANGE ACT"), in each case if required
          for the initial issuance thereof;

          (iii)any necessary qualification or registration under applicable
          state securities laws or the availability of an exemption from such
          qualification and registration; and

          (iv) the receipt by the Trustee of an Officers' Certificate and an
          Opinion of Counsel each stating that (A) the terms of the issuance of
          the Common Stock are in conformity with this Indenture and (B) the
          shares of Common Stock to be issued by the Company in payment of the
          Purchase Price in respect of Securities have been duly authorized and,
          when issued and delivered pursuant to the terms of this Indenture in
          payment of the Purchase Price in respect of the Securities, will be
          validly issued, fully paid and nonassessable and shall be free of any
          preemptive rights and any lien or adverse claim (provided that such
          Opinion of Counsel may state that, insofar as it relates to the
          absence of such preemptive rights, liens and adverse claims, it is
          given upon the best knowledge of such counsel), and, in the case of
          such Officers' Certificate, that conditions (i), (ii) and (iii) above
          have been satisfied and, in the case of such Opinion of Counsel, that
          conditions (ii) and (iii) above have been satisfied.

     Such Officers' Certificate shall also set forth the number of shares of
Common Stock to be issued for each $1,000 Principal Amount of Securities and the
Sale Price of a share of Common Stock on each of the seven Business Days prior
to the Purchase Date.  The Company may elect to pay in Common Stock only if the
information necessary to calculate the Market Price is reported in THE WALL
STREET JOURNAL or another daily newspaper of national circulation.  If such
conditions are not satisfied prior to or on the Purchase Date and the Company
elected to purchase the Securities pursuant to this Section 3.08 through the
issuance of shares of Common Stock, the Company shall pay, without further
notice, the Purchase Price in cash.


                                       22



     The "MARKET PRICE" means the average of the Sale Price of the Common Stock
for the five Trading Day period ending on the third Trading Day prior to the
related Purchase Date, appropriately adjusted to take into account the actual
occurrence, during the seven Trading Days preceding such Purchase Date, of any
event described in Section 10.06, 10.07 or 10.08; SUBJECT, HOWEVER, to the
conditions set forth in Sections 10.09 and 10.10.

     (e)  NOTICE OF ELECTION.  The Company shall send notices of its election
(the "COMPANY NOTICE") to purchase with cash or Common Stock or any combination
thereof to the Holders (and to beneficial owners as required by applicable law)
in the manner provided in Section 3.03.  The Company Notice shall be sent to
Holders (and to beneficial owners as required by applicable law) on a date not
less than 20 Business Days prior to the Purchase Date (such date not less than
20 Business Days prior to the Purchase Date being herein referred to as the
"COMPANY NOTICE DATE").  Such notices shall state the manner of payment elected
and shall contain the following information:

     In the event the Company has elected to pay the Purchase Price (or any
specified percentage thereof) with Common Stock, the notice shall:

          (1) state that each Holder will receive Common Stock with a Market
     Price determined as of a specified date prior to the Purchase Date equal to
     such specified percentage of the Purchase Price of the Securities held by
     such Holder (except for any cash amount to be paid in lieu of fractional
     shares);

          (2)  set forth the method of calculating the Market Price of the
     Common Stock; and

          (3)  state that because the Market Price of Common Stock will be
     determined prior to the Purchase Date, Holders will bear the market risk
     with respect to the value of the Common Stock to be received from the date
     such Market Price is determined to the Purchase Date.

     In any case, each notice shall include a form of Purchase Notice to be
completed by the Securityholder and shall state:

          (i) the Purchase Price and Conversion Rate;

          (ii) the name and address of the Paying Agent and the Conversion Agent
          and of the office or agency referred to in Section 4.05;

          (iii) that Securities as to which a Purchase Notice has been given may
          be converted into Common Stock at any time prior to the close of
          business on the applicable Purchase Date only if the applicable
          Purchase Notice has been withdrawn in accordance with the terms of
          this Indenture;


                                       23



          (iv) that Securities must be surrendered to the Paying Agent or to the
          office or agency referred to in Section 4.05 to collect payment;

          (v) that the Purchase Price for any security as to which a Purchase
          Notice has been given and not withdrawn will be paid promptly
          following the later of the Purchase Date and the time of surrender of
          such Security as described in (iv);

          (vi) the procedures the Holder must follow to exercise rights under
          Section 3.08 and a brief description of those rights;

          (vii) briefly, the conversion rights of the Securities and that
          Holders who want to convert Securities must satisfy the requirements
          set forth in paragraph 8 of the Securities; and

          (viii) the procedures for withdrawing a Purchase Notice (including,
          without limitation, for a conditional withdrawal pursuant to the terms
          of Section 3.08(a)(1)(D) or Section 3.10).

     At the Company's written request, the Trustee shall give such notice in the
Company's name and at the Company's expense;
PROVIDED, HOWEVER, that, in all cases, the text of such notice shall be prepared
by the Company.

     Upon determination of the actual number of shares of Common Stock to be 
issued for each $1,000 Principal Amount of Securities, the Company will 
publish such determination in THE WALL STREET JOURNAL or another daily 
newspaper of national circulation and furnish the Trustee with an affidavit 
of publication.

     (f)  COVENANTS OF THE COMPANY.  All shares of Common Stock delivered 
upon purchase of the Securities shall be newly issued shares or treasury 
shares, shall be duly authorized, validly issued, fully paid and 
nonassessable and shall be free from preemptive rights and free of any lien 
or adverse claim.

     The Company shall use its best efforts to list or cause to have quoted 
any shares of Common Stock to be issued to purchase Securities on the 
principal national securities exchange or over-the-counter or other domestic 
market on which any other shares of the Common Stock are then listed or 
quoted.  The Company will promptly inform the Trustee in writing of any such 
listing.

     (g)  PROCEDURE UPON PURCHASE.  The Company shall deposit cash (in 
respect of a cash purchase under Section 3.08(c) or for fractional interests, 
as applicable) or shares of Common Stock, or any combination thereof, as 
applicable, at the time and in the manner as provided in Section 3.11, 
sufficient to pay the aggregate Purchase Price of all Securities to be 
purchased pursuant to this 

                                     24



Section 3.08.  As soon as practicable after the later of the Purchase Date 
and the date such Securities are surrendered to the Paying Agent or at the 
office or agency referred to in Section 4.05, the Company shall deliver to 
each Holder entitled to receive Common Stock through the Paying Agent a 
certificate for the number of full shares of Common Stock issuable in payment 
of the Purchase Price and cash in lieu of any fractional interests.  The 
person in whose name the certificate for Common Stock is registered shall be 
treated as a holder of record of such Common Stock on the Business Day 
following the related Purchase Date.  Subject to Section 3.08(d), no payment 
or adjustment will be made for dividends on the Common Stock the record date 
for which occurred prior to the Purchase Date.

     (h)  TAXES.  If a Holder of a Security is paid in Common Stock, the 
Company shall pay any documentary, stamp or similar issue or transfer tax due 
on such issue of shares of Common Stock.  However, the Holder shall pay any 
such tax which is due because the Holder requests the shares of Common Stock 
to be issued in a name other than the Holder's name.  The Paying Agent may 
refuse to deliver the certificates representing the Common Stock being issued 
in a name other than the Holder's name until the Paying Agent receives a sum 
sufficient to pay any tax which will be due, as set forth in an Officers' 
Certificate, because the shares of Common Stock are to be issued in a name 
other than the Holder's name. Nothing herein shall preclude any income tax 
withholding required by law or regulations.

     SECTION 3.09.  PURCHASE OF SECURITIES AT OPTION OF THE HOLDER UPON CHANGE
                    IN CONTROL.  

     (a) If on or prior to June 12, 2001 there shall have occurred a Change 
in Control, Securities shall be purchased, at the option of the Holder 
thereof, by the Company at the purchase price specified in paragraph 6 of the 
Securities (the "CHANGE IN CONTROL PURCHASE PRICE"), on the date that is 35 
Business Days after the occurrence of the Change of Control (the "CHANGE IN 
CONTROL PURCHASE DATE"), subject to satisfaction by or on behalf of the 
Holder of the requirements set forth in Section 3.09(c).

     A "CHANGE IN CONTROL" shall be deemed to have occurred at such time 
after the original issuance of the Securities as either of the following 
events shall occur:

          (i) There shall be consummated any consolidation or merger of the 
     Company in which the Company is not the continuing or surviving corporation
     or pursuant to which the Common Stock would be converted into cash,
     securities or other property, other than a consolidation or merger of the
     Company in which the holders of Common Stock immediately prior to the
     consolidation or merger have, directly or indirectly, at least a majority
     of the Common Stock of the continuing or surviving corporation immediately
     after such consolidation or merger; or

                                     25



          (ii) There is a report filed by any person, including its Affiliates
     and Associates, other than Zell/Chilmark, the Company, any Subsidiary of
     the Company, or any employee benefit plan of either the Company or any
     Subsidiary of the Company, on Schedule 13D or 14D-1 (or any successor
     schedule, form or report) pursuant to the Exchange Act, disclosing that
     such person (for the purposes of this Section 3.09 only, the term "person"
     shall include a "person" within the meaning of Section 13(d)(3) or Section
     14(d)(2) of the Exchange Act or any successor provision to either of the
     foregoing) has become the beneficial owner (as the term "BENEFICIAL OWNER"
     is defined under Rule 13d-3 or any successor rule or regulation promulgated
     under the Exchange Act) of 50% or more of the voting power of the Company's
     Common Stock then outstanding; PROVIDED, HOWEVER, that a person shall not
     be deemed beneficial owner of, or to own beneficially, (A) any securities
     tendered pursuant to a tender or exchange offer made by or on behalf of
     such person or any of such person's Affiliates or Associates until such
     tendered securities are accepted for purchase or exchange thereunder, or
     (B) any securities if such beneficial ownership (1) arises solely as a
     result of a revocable proxy delivered in response to a proxy or consent
     solicitation made pursuant to, and in accordance with, the applicable rules
     and regulations under the Exchange Act, and (2) is not also then reportable
     on Schedule 13D (or any successor schedule, form or report) under the
     Exchange Act. 

     Notwithstanding the foregoing provisions of this Section 3.09, a Change 
in Control shall not be deemed to have occurred if at any time the Company, 
any Subsidiary, any employee stock ownership plan or any other employee 
benefit plan of the Company or any Subsidiary, or any person holding Common 
Stock for or pursuant to the terms of any such employee benefit plan files or 
becomes obligated to file a report under or in response to Schedule 13D or 
Schedule 14D-1 (or any successor schedule, form or report) under the Exchange 
Act disclosing beneficial ownership by it of shares of Common Stock, whether 
in excess of 50% or otherwise.

     "ASSOCIATE" shall have the meaning ascribed to such term in Rule 12b-2 
of the General Rules and Regulations under the Exchange Act, as in effect on 
the date hereof.

     (b)  Within 15 Business Days after the occurrence of a Change in 
Control, (i) the Company shall mail a written notice of such Change in 
Control by first-class mail to the Trustee and to each Holder (and to 
beneficial owners if required by applicable law) and (ii) the Company shall 
cause a copy of such notice to be published in THE WALL STREET JOURNAL or 
another daily newspaper of national circulation.  The notice shall include a 
form of Change in Control Purchase Notice to be completed by the 
Securityholder and shall state:

          (1) the events causing a Change in Control and the date such Change 
     in Control is deemed to have occurred for purposes of this Section 3.09;

                                     26



          (2) the date by which the Change in Control Purchase Notice pursuant
     to this Section 3.09 must be given;

          (3) the Change in Control Purchase Date;

          (4) the Change in Control Purchase Price;

          (5) the name and address of the Paying Agent and the Conversion Agent
     and the office or agency referred to in Section 4.05;

          (6) the Conversion Rate and any adjustments thereto;

          (7) that Securities as to which a Change in Control Purchase Notice
     has been given may be converted into Common Stock (or, in lieu thereof,
     cash, if the Company shall so elect) at any time prior to the close of
     business on the Change of Control Purchase Date only if the Change in
     Control Purchase Notice has been withdrawn by the Holder in accordance with
     the terms of this Indenture;

          (8) that Securities must be surrendered to the Paying Agent or the
     office or agency referred to in Section 4.05 to collect payment;

          (9) that the Change in Control Purchase Price for any Security as to
     which a Purchase Notice has been duly given and not withdrawn will be paid
     promptly following the later of the Change in Control Purchase Date and the
     time of surrender of such Security as described in (8);

          (10) the procedures the Holder must follow to exercise rights under
     this Section 3.09 and a brief description of those rights;

          (11) briefly, the conversion rights of the Securities;  and

          (12) the procedures for withdrawing a Change in Control Purchase
     Notice.

     (c) A Holder may exercise its rights specified in Section 3.09(a) upon 
delivery of a written notice of purchase (a "CHANGE IN CONTROL PURCHASE 
NOTICE") to the Paying Agent or to the office or agency referred to in 
Section 4.05 at any time prior to the close of business on the Change in 
Control Purchase Date, stating:

          (1) the certificate number of the Security which the Holder will
     deliver to be purchased;

                                     27



          (2) the portion of the Principal Amount of the Security which the
     Holder will deliver to be purchased, which portion must be $1,000 or an
     integral multiple thereof; and

          (3) that such Security shall be purchased on the Change in Control
     Purchase Date pursuant to the terms and conditions specified in paragraph 6
     of the Securities.

     Receipt of the Security by the Paying Agent prior to, on or after the 
Change in Control Purchase Date (together with all necessary endorsements), 
at the offices of the Paying Agent or to the office or agency referred to in 
Section 4.05 shall be a condition to the receipt by the Holder of the Change 
in Control Purchase Price therefor; PROVIDED, HOWEVER, that such Change in 
Control Purchase Price shall be so paid pursuant to this Section 3.09 only if 
the Security so delivered to the Paying Agent or such office or agency shall 
conform in all respects to the description thereof set forth in the related 
Change in Control Purchase Notice.

     The Company shall purchase from the Holder thereof, pursuant to this 
Section 3.09, a portion of a Security if the Principal Amount of such portion 
is $1,000 or an integral multiple of $1,000.  Provisions of this Indenture 
that apply to the purchase of all of a Security also apply to the purchase of 
such portion of such Security.

     Any purchase by the Company contemplated pursuant to the provisions of 
this Section 3.09 shall be consummated by the delivery of the consideration 
to be received by the Holder promptly following the later of the Change in 
Control Purchase Date and the date such Securities are surrendered to the 
Paying Agent or at the office or agency referred to in Section 4.05.

     Notwithstanding anything herein to the contrary, any Holder delivering 
to the Paying Agent or to the office or agency referred to in Section 4.05 
the Change in Control Purchase Notice contemplated by this Section 3.09(c) 
shall have the right to withdraw such Change in Control Purchase Notice at 
any time prior to or on the Change in Control Purchase Date by delivery of a 
written notice of withdrawal to the Paying Agent or to such office or agency 
in accordance with Section 3.10.

     The Paying Agent shall promptly notify the Company of the receipt by it 
of any Change in Control Purchase Notice or written withdrawal thereof.

     SECTION 3.10. EFFECT OF PURCHASE NOTICE OR CHANGE IN CONTROL PURCHASE 
NOTICE.  Upon receipt by the Paying Agent of the Purchase Notice or Change in 
Control Purchase Notice specified in Section 3.08(a) or Section 3.09(c), as 
applicable, the Holder of the Security in respect of which such Purchase 
Notice or Change in Control Purchase Notice, as the case may be, was given 
shall (unless such Purchase Notice or Change in Control Purchase Notice is 
withdrawn as specified in the following two paragraphs) thereafter be 
entitled to receive solely the Purchase Price or Change in Control Purchase 
Price, as the case may be, with respect to such Security.  Such Purchase 
Price 

                                     28



or Change in Control Purchase Price shall be paid to such Holder promptly 
following the later of (x) the Business Day following the Purchase Date or 
the Change in Control Purchase Date, as the case may be, with respect to such 
Security (provided the conditions in Section 3.08(a) or Section 3.09(c), as 
applicable, have been satisfied) and (y) the time of delivery of such 
Security to the Paying Agent or to the office or agency referred to in 
Section 4.05 by the Holder thereof in the manner required by Section 3.08(a) 
and (g) or Section 3.09(c), as applicable. Securities in respect of which a 
Purchase Notice or Change in Control Purchase Notice, as the case may be, has 
been given by the Holder thereof may not be converted into shares of Common 
Stock on or after the date of the delivery of such Purchase Notice or Change 
in Control Purchase Notice, as the case may be, unless such Purchase Notice 
or Change in Control Purchase Notice, as the case may be, has first been 
validly withdrawn as specified in the following two paragraphs.

     A Purchase Notice or Change in Control Purchase Notice, as the case may 
be, may be withdrawn by means of a written notice of withdrawal delivered to 
the office of the Paying Agent or to the office or agency referred to in 
Section 4.05 at any time on or prior to the Purchase Date or the Change in 
Control Purchase Date, as the case may be, specifying:

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

          (2) the Principal Amount of the Security with respect to which such
     notice of withdrawal is being submitted; and

          (3) the Principal Amount, if any, of such Security which remains
     subject to the original Purchase Notice or Change in Control Purchase
     Notice, as the case may be, and which has been or will be delivered for
     purchase by the Company.

     A written notice of withdrawal of a Purchase Notice may be in the form 
set forth in the preceding paragraph or may be in the form of (i) a 
conditional withdrawal contained in a Purchase Notice pursuant to the terms 
of Section 3.08(a)(1)(D) or (ii) a conditional withdrawal containing the 
information set forth in Section 3.08(a)(1)(D) and the preceding paragraph 
and contained in a written notice of withdrawal delivered to the Paying Agent 
as set forth in the preceding paragraph.

     There shall be no purchase of any Securities pursuant to Sections 3.08 
(other than through the issuance of Common Stock in payment of the Purchase 
Price, including cash in lieu of fractional shares of Common Stock) or 3.09 
if there has occurred (prior to, on or after, as the case may be, the giving, 
by the Holders of such Securities, of the required Purchase Notice or Change 
in Control Purchase Notice, as the case may be) and is continuing an Event of 
Default (other than a default in the payment of the Purchase Price or Change 
in Control Purchase Price, as the case may be, with respect to such 
Securities). The Paying Agent will promptly return to the respective Holders 
thereof any Securities (x) with respect to which a Purchase Notice or Change 
in Control Purchase Notice,

                                     29


as the case may be, has been withdrawn in compliance with this Indenture, or 
(y) held by it during the continuance of an Event of Default (other than a 
default in the payment of the Purchase Price or Change in Control Purchase 
Price, as the case may be, with respect to such Securities) in which case, 
upon such return, the Purchase Notice or Change in Control Purchase Notice 
with respect thereto shall be deemed to have been withdrawn.

     SECTION 3.11. DEPOSIT OF PURCHASE PRICE OR CHANGE IN CONTROL PURCHASE 
PRICE. Prior to 3:00 p.m. (local time in The City of New York) on the 
Business Day following the Purchase Date or the Change in Control Purchase 
Date, as the case may be, the Company shall deposit with the Trustee or with 
the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of 
either of them is acting as Paying Agent, shall segregate and hold in trust 
as provided in Section 2.04) an amount of cash in immediately available funds 
or securities, if expressly permitted hereunder, sufficient to pay the 
aggregate Purchase Price or Change in Control Purchase Price, as the case may 
be, of all the Securities or portions thereof which are to be purchased as of 
the Purchase Date or Change in Control Purchase Date, as the case may be.

     SECTION 3.12. SECURITIES PURCHASED IN PART.  Any Security which is to be 
purchased only in part shall be surrendered at the office of the Paying Agent 
or the office or agency referred to in Section 4.05 (with, if the Company or 
the Trustee so requires, due endorsement, or a written instrument of transfer 
in form satisfactory to the Company and the Trustee executed by the Holder or 
such Holder's attorney duly authorized in writing) and the Company shall 
execute and the Trustee shall authenticate and deliver to the Holder of such 
Security, without service charge, a new Security or Securities, of any 
authorized denomination as requested by such Holder in aggregate Principal 
Amount equal to, and in exchange for, the portion of the Principal Amount of 
the Security so surrendered which is not purchased.

     SECTION 3.13. COVENANT TO COMPLY WITH SECURITIES LAWS UPON PURCHASE OF 
SECURITIES.  In connection with any offer to purchase or purchase of 
Securities under Section 3.08 or 3.09 hereof, the Company shall (i) comply 
with Rule 13e-4 and Rule 14e-1 under the Exchange Act, if applicable, (ii) 
file the related Schedule 13E-4 (or any successor schedule, form or report) 
under the Exchange Act, if applicable, and (iii) otherwise comply with all 
Federal and state securities laws regulating the offer and delivery of shares 
of Common Stock upon purchase of the Securities (including positions of the 
SEC under applicable no-action letters) so as to permit the rights and 
obligations under Sections 3.08 and 3.09 to be exercised in the time and in 
the manner specified in Sections 3.08 and 3.09.

     SECTION 3.14. REPAYMENT TO THE COMPANY.  The Trustee and the Paying 
Agent shall return to the Company, upon written request, any cash or shares 
of Common Stock, together with interest on such cash as hereinafter provided 
and dividends on such shares of Common Stock, if any, (subject to the 
provisions of Section 7.01(f)) held by them for the payment of a Purchase 
Price or Change in Control Purchase Price, as the case may be, of the 
Securities that remain unclaimed as

                                      30


provided in paragraph 12 of the Securities; PROVIDED, HOWEVER, that to the 
extent that the aggregate amount of cash or shares of Common Stock deposited 
by the Company pursuant to Section 3.11 exceeds the aggregate Purchase Price 
or Change in Control Purchase Price, as the case may be, of the Securities or 
portions thereof to be purchased, then promptly after the Business Day 
following the Purchase Date or Change in Control Purchase Date, as the case 
may be, the Trustee shall return any such excess to the Company together with 
interest as hereinafter provided or dividends, if any, thereon (subject to 
the provisions of Section 7.01(f)).  Any cash deposited with the Trustee or 
with the Paying Agent pursuant to Section 3.11 hereof, shall be invested by 
the Trustee or Paying Agent, as applicable, in short term obligations of, or 
fully guaranteed by, the United States of America, or commercial paper rated 
A-1 or better by Standard and Poor's Corporation or P-1 or better by Moody's 
Investors Service, Inc. or the Dreyfus Cash Management Fund or the American 
AAdvantage Money Market Fund, as specifically directed in writing by the 
Company.  Interest earned on such investments shall be repaid to the Company 
pursuant to this Section 3.14. Except as provided for in this Section 3.14, 
the Trustee shall be under no liability for interest on any money received by 
it pursuant to this Indenture.

                                  COVENANTS


     SECTION 4.01.  PAYMENT OF SECURITIES.  The Company shall promptly make 
all payments in respect of the Securities on the dates and in the manner 
provided in the Securities or pursuant to this Indenture.  Principal Amount, 
Issue Price, accrued Original Issue Discount, Redemption Price, Purchase 
Price, Change in Control Purchase Price and interest, if any, shall be 
considered paid on the applicable date due if on such date the Trustee or the 
Paying Agent holds, in accordance with this Indenture, cash or securities, if 
expressly permitted hereunder, sufficient to pay all such amounts then due.

     The Company shall, to the extent permitted by law, pay interest on 
overdue amounts at the per annum rate of interest set forth in paragraph 1 of 
the Securities, compounded semi-annually, which interest on overdue amounts 
(to the extent payment of such interest shall be legally enforceable) shall 
accrue from the date such overdue amounts were originally due and payable.

     SECTION 4.02.  SEC REPORTS.  The Company shall file with the Trustee, 
within 15 days after it files such annual and quarterly reports, information, 
documents and other reports with the SEC, copies of its annual and quarterly 
reports and of the information, documents and other reports (or copies of 
such portions of any of the foregoing as the SEC may by rules and regulations 
prescribe) which the Company is required to file with the SEC pursuant to 
Section 13 or 15(d) of the Exchange Act (or any such successor provisions 
thereto).  In the event the Company is at any

                                      31


time no longer subject to the reporting requirements of Section 13 or 15(d) 
of the Exchange Act (or any such successor provisions), it shall continue to 
provide the Trustee with reports containing substantially the same 
information as would have been required to be filed with the SEC had the 
Company continued to have been subject to such reporting requirements, and 
the Trustee shall make any such reports available to Securityholders upon 
request.  In such event, such reports shall be provided at the times the 
Company would have been required to provide reports had it continued to have 
been subject to such reporting requirements.  The Company also shall comply 
with the other provisions of TIA Section 314(a), to the extent such 
provisions are applicable.

     SECTION 4.03.  COMPLIANCE CERTIFICATE; NOTICE OF DEFAULTS.  

     (a) 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 December 31, 1996) a certificate of the principal executive officer, the 
principal financial officer, or principal accounting officer of the Company 
stating whether or not, to the knowledge of the signer, the Company has 
complied with all conditions and covenants on its part contained in this 
Indenture and, if the signer has obtained knowledge of any default by the 
Company in the performance, observance or fulfillment of any such condition 
or covenant, specifying each such default and the nature thereof.  For the 
purpose of this Section 4.03, compliance shall be determined without regard 
to any grace period or requirement of notice provided pursuant to the terms 
of this Indenture.

     (b)  The Company shall file with the Trustee written notice of the 
occurrence of any Default or Event of Default within five Business Days of 
its becoming aware of such Default or Event of Default.

     SECTION 4.04.  FURTHER INSTRUMENTS AND ACTS.  Upon request of the 
Trustee, the Company will execute and deliver such further instruments and do 
such further acts as may be reasonably necessary or proper to carry out more 
effectively the purposes of this Indenture.

     SECTION 4.05.  MAINTENANCE OF OFFICE OR AGENCY.  The Company will 
maintain in the Borough of Manhattan, The City of New York, in such location 
as may be required by the rules of any securities exchange or quotation 
system on which the Securities may from time to time be listed, an office or 
agency where Securities may be presented or surrendered for payment, where 
Securities may be surrendered for registration of transfer, exchange, 
purchase, redemption or conversion and where notices and demands to or upon 
the Company in respect of the Securities and this Indenture may be served.  
The office of the Trustee in The City of New York, at which at any particular 
time its corporate trust business shall be principally administered, which 
office on the date hereof is located at 101 Barclay Street, Floor 21 West, 
New York, New York 10286, shall be such office or agency for all of the 
aforesaid purposes unless the Company shall maintain some other office or 
agency for such purposes and shall give prompt written notice to the Trustee 
of the location, and any change of location, of such other office or agency.  
If at any time the Company shall fail to maintain

                                      32


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 address of the Trustee set forth in Section 11.02.

     The Company may also from time to time designate one or more other 
offices or agencies where the Securities may be presented or surrendered for 
any or all such purposes and may from time to time rescind such designations; 
PROVIDED, HOWEVER, that no such designation or rescission shall in any manner 
relieve the Company of its obligation to maintain an office or agency in The 
Borough of Manhattan, The City of New York, for such purposes.

     SECTION 4.06.  CALCULATION OF ORIGINAL ISSUE DISCOUNT.  The Company 
shall file with the Trustee promptly following the end of each calendar year 
a written notice specifying the amount of original issue discount (including 
daily rates and accrual periods) accrued on outstanding Securities as of the 
end of such year.

                            SUCCESSOR CORPORATION

     SECTION 5.01.  WHEN COMPANY MAY MERGE OR TRANSFER ASSETS.  So long as 
any Securities shall be outstanding, the Company shall not consolidate with 
or merge into any other corporation or other person or convey, transfer or 
lease its properties and assets substantially as an entirety to any person 
(such successor corporation or person, as the case may be, shall in this 
Article 5 be referred to as the "Successor Company"), unless

          (1) either (x) the Company shall be the continuing corporation or 
     (y) the Successor Company (if other than the Company) shall be organized 
     and existing under the laws of the United States of America or any State 
     or the District of Columbia, and shall expressly assume by an indenture 
     supplemental hereto, executed and delivered to the Trustee, in form 
     satisfactory to the Trustee, the due and punctual payment of the 
     principal of and premium, if any, and interest, if any, on all the 
     Securities and the performance of every covenant of this Indenture and 
     in the Securities on the part of the Company to be performed or observed;

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

          (3) the Company has delivered to the Trustee an Officers' 
     Certificate and an Opinion of Counsel each stating that such 
     consolidation, merger, conveyance, transfer or lease and

                                      33


     such supplemental indenture comply with this Article and that all 
     conditions precedent herein provided for relating to such transaction 
     have been complied with.

     SECTION 5.02.  SUCCESSOR COMPANY SUBSTITUTED.  Upon any consolidation 
with or merger into any other corporation or other person, or any conveyance, 
transfer or lease of the properties and assets of the Company substantially 
as an entirety in accordance with Section 5.01, the Successor Company or 
person formed by such consolidation or into which the Company is merged or to 
which such conveyance, transfer or lease is made shall succeed to, and be 
substituted for, and may exercise every right and power of, the Company under 
this Indenture with the same effect as if such Successor Company or person 
had been named as the Company herein, and thereafter, except in the case of a 
lease and obligations the Company may have under a supplemental indenture 
pursuant to Section 10.14, the predecessor corporation shall be relieved of 
all obligations and covenants under this Indenture and the Securities.  
Subject to Section 9.06, the Company, the Trustee and the successor person 
shall enter into a supplemental indenture to evidence the succession and 
substitution of such successor person and such discharge and release of the 
Company.


                                      ARTICLE 6

                                DEFAULTS AND REMEDIES


     SECTION 6.01.  EVENTS OF DEFAULT.  An "EVENT OF DEFAULT" occurs if:

          (1) the Company defaults in the payment of the Principal Amount, Issue
     Price, accrued Original Issue Discount, Redemption Price, Purchase Price or
     Change in Control Purchase Price on any Security when the same becomes due
     and payable at its Stated Maturity, upon redemption, upon declaration, when
     due for purchase by the Company or otherwise, whether or not such payment
     shall be prohibited by this Indenture;

          (2) the Company fails to comply with any of its agreements in the
     Securities or this Indenture and such failure continues for 60 days after
     receipt by the Company of a Notice of Default;

          (3) the Company pursuant to or within the meaning of any Bankruptcy
     Law:

               (A) commences a voluntary case or proceeding;

               (B) consents to the entry of an order for relief against it in an
          involuntary case or proceeding or the commencement of any case against
          it;

                                      34


               (C) consents to the appointment of a Custodian of it or for any
          substantial part of its property;

               (D) makes a general assignment for the benefit of its creditors;

               (E) files a petition in bankruptcy or answer or consent seeking
          reorganization or relief; or

               (F) consents to the filing of such petition or the appointment of
          or taking possession by a Custodian;

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

               (A) is for relief against the Company in an involuntary case or
          proceeding, or adjudicates the Company insolvent or bankrupt;

               (B) appoints a Custodian of the Company or for any substantial
          part of its property; or

               (C) orders the winding up or liquidation of the Company;

     and the order or decree remains unstayed and in effect for 60 days;

          (5) the Company fails to deliver shares of Common Stock or pay cash in
     lieu of fractional shares in accordance with the terms hereof when such
     Common Stock or cash in lieu of fractional shares is required to be
     delivered, upon conversion of a Security and such failure is not remedied
     for a period of 10 days; or

          (6) (a) default shall occur (i) in the payment of any principal on any
     debt for borrowed money of the Company (excluding any non-recourse debt),
     in an aggregate principal amount in excess of $10.0 million, when due at
     its final maturity after giving effect to any applicable grace period and
     the holder thereof shall have taken affirmative action to enforce the
     payment thereof, or (ii) in the performance of any term or provision of any
     debt for borrowed money of the Company (excluding any non-recourse debt) in
     an aggregate principal amount in excess of $10.0 million that results in
     such debt becoming or being declared due and payable prior to the date on
     which it would otherwise become due and payable, unless, in the case of
     either clause (i) or (ii) above, (x) such acceleration or action to enforce
     payment, as the case may be, has been rescinded or annulled, (y) such debt
     has been discharged or (z) a sum sufficient to discharge in full such debt
     has been deposited in trust by or on behalf of the Company, in each case,
     within a period of 10 days after there has

                                         35




     been given, by registered or certified mail, to the Company by the Trustee
     or to the Company and the Trustee by the Holders of at least 25% in
     aggregate Principal Amount of the Securities at the time outstanding,
     a written notice specifying such default or defaults and stating that
     such notice is a "Notice of Default" hereunder.

     A Default under clause (2) above is not an Event of Default until the 
Trustee notifies the Company, or the Holders of at least 25% in aggregate 
Principal Amount of the Securities at the time outstanding notify the Company 
and the Trustee, of the Default and the Company does not cure such Default 
within the time specified in clause (2) above after receipt of such notice.  
Any such notice must specify the Default, demand that it be remedied and 
state that such notice is a "Notice of Default."

     The Company shall deliver to the Trustee, within 30 days after it 
becomes aware of the occurrence thereof, written notice of any event which 
with the giving of notice and the lapse of time or both would become an Event 
of Default under clause (2) or clause (6), its status and what action the 
Company is taking or proposes to take with respect thereto.

     SECTION 6.02.  ACCELERATION.  If an Event of Default (other than an 
Event of Default specified in Section 6.01(3) or (4)) occurs and is 
continuing, unless the Principal Amount of all the Securities shall have 
already become due and payable, either the Trustee by notice to the Company, 
or the Holders of at least 25% in aggregate Principal Amount of the 
Securities at the time outstanding by notice to the Company and the Trustee, 
may declare the Issue Price and accrued Original Issue Discount through the 
date of declaration on all the Securities to be immediately due and payable, 
whereupon such Issue Price and accrued Original Issue Discount shall be due 
and payable immediately; provided that, if an Event of Default specified in 
Section 6.01(3) or (4) occurs and is continuing, the Issue Price and accrued 
Original Issue Discount on all the Securities through the date of the 
occurrence of such Event of Default shall become and be immediately due and 
payable without any declaration or other act on the part of the Trustee or 
any Securityholders.  The Holders of a majority in aggregate Principal Amount 
of the Securities at the time outstanding, by notice to the Trustee (and 
without notice to any other Securityholder) may rescind an acceleration and 
its consequences if the rescission would not conflict with any judgment or 
decree and if all existing Events of Default have been cured or waived except 
nonpayment of the Issue Price and accrued Original Issue Discount that have 
become due solely as a result of acceleration and if all amounts due to the 
Trustee under Section 7.06 have been paid.  No such rescission shall affect 
any subsequent Default or impair any right consequent thereto.

     SECTION 6.03.  OTHER REMEDIES.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of the Issue Price and accrued Original Issue Discount on the Securities or to
enforce the performance of any provision of the Securities or this Indenture.

                                         36




     The Trustee may maintain a proceeding even if the Trustee does not 
possess any of the Securities or does not produce any of the Securities in 
the proceeding.  A delay or omission by the Trustee or any Securityholder in 
exercising any right or remedy accruing upon an Event of Default shall not 
impair the right or remedy or constitute a waiver of, or acquiescence in, the 
Event of Default.  No remedy is exclusive of any other remedy.  All available 
remedies are cumulative.

     SECTION 6.04.  WAIVER OF PAST DEFAULTS.  The Holders of a majority in 
aggregate Principal Amount of the Securities at the time outstanding, by 
notice to the Trustee (and without notice to any other Securityholder), may 
waive an existing Default and its consequences except (a) an Event of Default 
described in Section 6.01(1), (b) a Default in respect of a provision that 
under Section 9.02 cannot be amended without the consent of each 
Securityholder affected or (c) a Default under Article 10.  When a Default is 
waived, it is deemed cured and shall cease to exist, but no such waiver shall 
extend to any subsequent or other Default or impair any consequent right.  

     SECTION 6.05.  CONTROL BY MAJORITY.  The Holders of a majority in 
aggregate Principal Amount of the Securities at the time outstanding may 
direct the time, method and place of conducting any proceeding for any remedy 
available to the Trustee or of exercising any trust or power conferred on the 
Trustee.  However, the Trustee may refuse to follow any direction that 
conflicts with law or this Indenture or that the Trustee determines in good 
faith is unduly prejudicial to the rights of other Securityholders or would 
involve the Trustee in personal liability unless the Trustee shall have been 
provided with reasonable security or indemnity against such liability 
satisfactory to the Trustee.  

     SECTION 6.06.  LIMITATION ON SUITS.  A Securityholder may not pursue any 
remedy with respect to this Indenture or the Securities unless:

          (1) the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

          (2) the Holders of at least 25% in aggregate Principal Amount of the
     Securities at the time outstanding make a written request to the Trustee to
     pursue the remedy;

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

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

          (5) the Holders of a majority in aggregate Principal Amount of the
     Securities at the time outstanding do not give the Trustee a direction
     inconsistent with the request during such 60-day period.

                                         37



                                                        
     A Securityholder may not use this Indenture to prejudice the rights of 
any other Securityholder or to obtain a preference or priority over any other 
Securityholder.

     SECTION 6.07.  RIGHTS OF HOLDERS TO RECEIVE PAYMENT.  Notwithstanding 
any other provision of this Indenture, the right of any Holder to receive 
payment of the Principal Amount, Issue Price, accrued Original Issue 
Discount, Redemption Price, Purchase Price, Change in Control Purchase Price 
or interest, if any, in respect of the Securities held by such Holder, on or 
after the respective due dates expressed in the Securities or any Redemption 
Date, and to convert the Securities in accordance with Article 10 or to bring 
suit for the enforcement of any such payment on or after such respective 
dates or the right to convert, shall not be impaired or affected adversely 
without the consent of each such Holder.

     SECTION 6.08.  COLLECTION SUIT BY TRUSTEE.  If an Event of Default 
described in Section 6.01(1) occurs and is continuing, the Trustee may 
recover judgment in its own name and as trustee of an express trust against 
the Company for the whole amount owing with respect to the Securities and the 
amounts provided for in Section 7.06.

     SECTION 6.09.  TRUSTEE MAY FILE PROOFS OF CLAIM.  In case of the 
pendency of any receivership, insolvency, liquidation, bankruptcy, 
reorganization, arrangement, adjustment, composition or other judicial 
proceeding relative to the Company or any other obligor upon the Securities 
or the property of the Company or of such other obligor or their creditors, 
the Trustee (irrespective of whether the Principal Amount, Issue Price, 
accrued Original Issue Discount, Redemption Price, Purchase Price, Change in 
Control Purchase Price or interest, if any, in respect of the Securities 
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 
on the Company for the payment of any such amount) shall be entitled and 
empowered, by intervention in such proceeding or otherwise:

          (a)  to file and prove a claim for the whole amount of the Principal
     Amount, Issue Price, accrued Original Issue Discount, Redemption Price,
     Purchase Price, Change in Control Purchase Price or interest, if any, and
     to file such other papers or documents as may be necessary or advisable in
     order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding; and

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

and any Custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder 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 Holders,

                                         38



to pay the Trustee any amount due it for the reasonable compensation, 
expenses, disbursements and advances of the Trustee, its agents and counsel, 
and any other amounts due the Trustee under Section 7.06.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

     SECTION 6.10. PRIORITIES.  If the Trustee collects any money pursuant to
this Article 6, it shall pay out the money in the following order:

         FIRST:  to the Trustee for amounts due under Section 7.06;

         SECOND:  to Securityholders for amounts due and unpaid on the
Securities for the Principal Amount, Issue Price, accrued Original Issue
Discount, Redemption Price, Purchase Price, Change in Control Purchase Price or
interest, if any, as the case may be, ratably, without preference or priority of
any kind, according to such amounts due and payable on the Securities; and

         THIRD:  the balance, if any, to the Company.

     The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10.  At least 15 days before such
record date, the Company shall mail to each Securityholder and the Trustee a
notice that states the record date, the payment date and amount to be paid.

     SECTION 6.11. UNDERTAKING FOR COSTS.  In any suit for the enforcement of 
any right or remedy under this Indenture or in any suit against the Trustee 
for any action taken or omitted by it as Trustee, a court in its discretion 
may require the filing by any party litigant (other than the Trustee) in the 
suit of an undertaking to pay the costs of the suit, and the court in its 
discretion may assess reasonable costs, including reasonable attorneys' fees 
and expenses, against any party litigant in the suit, having due regard to 
the merits and good faith of the claims or defenses made by the party 
litigant.  This Section 6.11 does not apply to a suit initiated by the 
Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of 
more than 10% in aggregate Principal Amount of the Securities at the time 
outstanding.  

     SECTION 6.12. NOTICE OF DEFAULTS.  The Trustee shall, within 90 days 
after the occurrence of any Default, mail to all Holders of Securities, as 
the names and addresses of such Holders appear on the books of registry of 
the Company, notice of all Defaults of which the Trustee shall be aware, 
unless such Defaults shall have been cured or waived before the giving of 
such notice; PROVIDED that, except in the case of a Default described in 
Section 6.01(1), the Trustee shall be protected in


                                         39


withholding such notice if and so long as the board of directors, the 
executive committee, or a trust committee of directors or Trust Officers of 
the Trustee in good faith determines that the withholding of such notice is 
in the interests of the Holders of Securities.

     SECTION 6.13. WAIVER OF STAY, EXTENSION OR USURY LAWS.  The Company 
covenants (to the extent it may lawfully do so) that it shall not at any time 
insist upon, or plead, or in any manner whatsoever claim or take the benefit 
or advantage of, any stay or extension law or any usury or other law, 
wherever enacted, now or at any time hereafter in force, that would prohibit 
or forgive the Company from paying all or any portion of the Principal 
Amount, Issue Price, accrued Original Issue Discount, Redemption Price, 
Purchase Price or Change in Control Purchase Price in respect of the 
Securities, or any interest on any such amounts, as contemplated herein, or 
that may affect the covenants or the performance of this Indenture or the 
Securities; and the Company (to the extent that it may lawfully do so) hereby 
expressly waives all benefit or advantage of any such law, and covenants that 
it will not hinder, delay or impede the execution of any power herein granted 
to the Trustee, but will suffer and permit the execution of every such power 
as though no such law had been enacted.

     (a) Before the Trustee acts or refrains from acting, it may require an 
Officers' Certificate or an Opinion of Counsel.  The Trustee shall not be 
liable for any action it takes or omits to take in good faith in reliance on 
such Officers' Certificate or Opinion of Counsel.

     (b)  The Trustee may act through agents and shall not be responsible for 
the misconduct or negligence of any agent appointed with due care.

     (c)  The Trustee shall not be liable for any action it takes or omits to 
take in good faith which it believes to be authorized or within its rights or 
powers.

     (d)  The Trustee may refuse to perform any duty or exercise any right or 
power or extend or risk its own funds or otherwise incur any financial 
liability unless it receives indemnity satisfactory to it against any loss, 
liability or expense.

     (e)  Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law.  Except as provided in
Section 3.14 hereof, the Trustee (acting


                                        40


in any capacity hereunder) shall be under no liability for interest on any 
money received by it hereunder.

     (f)  The Trustee undertakes to perform such duties and only such duties 
as are specifically set forth in this Indenture, and no implied covenants or 
obligations shall be read into this Indenture against the Trustee.

     (g)  In the absence of bad faith on its part, the Trustee may 
conclusively rely, as to the truth of the statements and the correctness of 
the opinions expressed therein, upon certificates or opinions furnished to 
the Trustee and conforming to the requirements of this Indenture; but in the 
case of any such certificates or opinions that by any provision 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 (but need not confirm or investigate the 
accuracy of mathematical calculations or other facts stated therein).

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

     (i)  The Trustee shall not be liable with respect to any action taken or 
omitted to be taken by it in good faith in accordance with the direction of 
the Holders of a majority in principal amount of the outstanding Securities 
relating to the time, method and place of conducting any proceeding for any 
remedy available to the Trustee, or exercising any trust or power conferred 
upon the Trustee, under this Indenture with respect to the Securities.

     (j) The Trustee may consult with counsel of its selection and the advice 
of such counsel or any Opinion of Counsel shall be full and complete 
authorization and protection in respect of any action taken, suffered or 
omitted by it hereunder in good faith and in reliance thereon.

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

     (l) No provision of this Indenture shall require the Trustee to expend 
or risk its own funds or otherwise incur any financial liability in the 
performance of any of its duties hereunder, or in the exercise of any of its 
rights or powers, if it shall have reasonable grounds for believing that 

                                      41



repayment of such funds or adequate indemnity against such risk or liability 
is not reasonably assured to it.

     (m) The Trustee may rely and shall be protected in acting or refraining 
from acting upon any resolution, certificate, statement, instrument, opinion, 
report, notice, request, direction, consent, order, bond, debenture, note, 
other evidence of indebtedness or other paper or document believed by it to 
be genuine and to have been signed or presented by the proper party or 
parties.

     SECTION 7.02.  INDIVIDUAL RIGHTS OF TRUSTEE.  The Trustee in its 
individual or any other capacity may become the owner or pledgee of 
Securities and may otherwise deal with the Company or its Affiliates with the 
same rights it would have if it were not Trustee.  Any Paying Agent, 
Registrar, Conversion Agent or co-registrar may do the same with like rights. 
However, the Trustee must comply with Sections 7.09 and 7.10.

     SECTION 7.03.  TRUSTEE'S DISCLAIMER.  The Trustee makes no 
representation as to the validity or adequacy of this Indenture or the 
Securities, it shall not be accountable for the Company's use of the proceeds 
from the Securities, it shall not be responsible for any statement in the 
registration statement for the Securities under the Securities Act or in the 
Indenture or the Securities (other than its certificate of authentication), 
or the determination as to which beneficial owners are entitled to receive 
any notices hereunder.

     SECTION 7.04.  NOTICE OF DEFAULTS.  The Trustee shall, within 90 days 
after the occurrence of any Default, mail to all Holders of Securities, as 
the names and addresses of such Holders appear on the books of registry of 
the Company, notice of all Defaults of which the Trustee shall be aware, 
unless such Defaults shall have been cured or waived before the giving of 
such notice.  Except in the case of a Default described in Section 6.01(1), 
the Trustee shall be protected in withholding such notice if and so long as 
the board of directors, the executive committee, or a trust committee of 
directors or Trust Officers of the Trustee in good faith determines that the 
withholding of such notice is in the interests of the Holders of Securities.  

     SECTION 7.05.  REPORTS BY TRUSTEE TO HOLDERS.  Within 60 days after each 
June 1 beginning with the June 1, 1998 following the date of this Indenture, 
the Trustee shall mail to each Securityholder a brief report dated as of such 
June 1 that complies with TIA Section 313(a), if required by said Section.  
The Trustee also shall comply with TIA Section 313(b).

     A copy of each report at the time of its mailing to Securityholders 
shall be provided to the Company and shall be filed with the SEC and each 
stock exchange on which the Securities are listed.  The Company agrees 
promptly to notify the Trustee whenever the Securities become listed on any 
stock exchange and of any delisting thereof.

                                       42


     SECTION 7.06.  COMPENSATION AND INDEMNITY.  The Company agrees:  

     (a)  to pay to the Trustee from time to time such compensation (in 
accordance with a fee schedule agreed upon from time to time) for all 
services rendered by it hereunder (which compensation shall not (to the 
extent permitted by law) be limited by any provision of law in regard to the 
compensation of a trustee of an express trust);

     (b)  to reimburse the Trustee (in accordance with a fee schedule agreed 
upon from time to time) upon its request and, if required by the Company, 
submission of reasonable documentation for all reasonable expenses, 
disbursements and advances incurred or made by the Trustee in accordance with 
any provision of this Indenture (including the reasonable compensation and 
the expenses, advances and disbursements of its agents and counsel), except 
any such expense, disbursement or advance as may be attributable to its 
negligence or bad faith; and

     (c)  to indemnify each of the Trustee or any predecessor Trustee for, 
and to hold it harmless against, any and all loss, liability, damage, claim 
or expense, including taxes (other than taxes based upon, measured or 
determined by the income of the Trustee), incurred without negligence or bad 
faith on its part, arising out of or in connection with the acceptance or 
administration of this trust, including the reasonable costs and expenses of 
defending itself against any claim or liability in connection with the 
exercise or performance of any of its powers or duties hereunder.

     The Trustee shall give the Company notice of any claim or liability for 
which the Trustee might be entitled to indemnification under subparagraph (c) 
of this Section 7.06, within a reasonable amount of time after a Trust 
Officer of the Trustee actually becomes aware of such claim or liability.  To 
secure the Company's payment obligations in this Section 7.06, the Trustee 
shall have a lien prior to the Securities on all money or property held or 
collected by the Trustee.

     The Company's payment obligations pursuant to this Section 7.06 shall 
survive the discharge of this Indenture.  When the Trustee incurs expenses 
after the occurrence of a Default specified in Section 6.01(3) or (4), the 
expenses are intended to constitute expenses of administration under the 
Bankruptcy Law. The provisions of this Section shall survive the termination 
of this Indenture.

     SECTION 7.07.  REPLACEMENT OF TRUSTEE.  The Trustee may resign by so 
notifying the Company; PROVIDED, HOWEVER, no such resignation shall be 
effective until a successor Trustee has accepted its appointment pursuant to 
this Section 7.07.  The Holders of a majority in aggregate Principal Amount 
of the Securities at the time outstanding may remove the Trustee by so 
notifying the Trustee and may appoint a successor Trustee (subject to the 
consent of the Company, such consent not to be unreasonably withheld).  The 
Company shall remove the Trustee if:

          (1) the Trustee fails to comply with Section 7.09;

                                       43



          (2) the Trustee is adjudged bankrupt or insolvent;

          (3) a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4) the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the 
office of Trustee for any reason, the Company shall promptly appoint, by 
resolution of its Board of Directors, a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its 
appointment to the retiring Trustee and to the Company.  Thereupon the 
resignation or removal of the retiring Trustee shall become effective, and 
the successor Trustee shall have all the rights, powers and duties of the 
Trustee under this Indenture.  The successor Trustee shall mail a notice of 
its succession to Securityholders.  The retiring Trustee shall promptly 
transfer all property held by it as Trustee to the successor Trustee, subject 
to the lien provided for in Section 7.06.

     If a successor Trustee does not take office within 30 days after the 
retiring Trustee resigns or is removed, the retiring Trustee, the Company or 
the Holders of a majority in aggregate Principal Amount of the Securities at 
the time outstanding may petition any court of competent jurisdiction for the 
appointment of a successor Trustee.

     If the Trustee fails to comply with Section 7.09, any Securityholder may 
petition any court of competent jurisdiction for the removal of the Trustee 
and the appointment of a successor Trustee.

     SECTION 7.08.  SUCCESSOR TRUSTEE BY MERGER.  If the Trustee consolidates 
with, merges or converts into, or transfers all or substantially all its 
corporate trust business or assets to, another corporation, the resulting, 
surviving or transferee corporation without any further act shall be the 
successor Trustee.

     SECTION 7.09.  ELIGIBILITY; DISQUALIFICATION.  The Trustee shall at all 
times satisfy the requirements of TIA Sections 310(a)(1) and 310(b).  The 
Trustee shall have a combined capital and surplus of at least $100,000,000 as 
set forth in its most recent published annual report of condition.  In 
determining whether the Trustee has conflicting interests as defined in TIA 
Section 310(b)(1), the provisions contained in the proviso to TIA Section 
310(b)(1) shall be deemed incorporated herein.

     SECTION 7.10. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.  The 
Trustee shall comply with TIA Section 311(a), excluding any creditor 
relationship listed in TIA Section 311(b).  A Trustee who has resigned or 
been removed shall be subject to TIA Section 311(a) to the extent indicated 
therein.

                                       44



     SECTION 7.11.  MONEY HELD IN TRUST.  Money held by the Trustee in trust 
hereunder need not be segregated from other funds except to the extent 
required by law.  The Trustee shall be under no liability for interest on any 
money received by it hereunder except as otherwise agreed in writing with the 
Company.

                                     ARTICLE 8
                                           
                                DISCHARGE OF INDENTURE


     SECTION 8.01.  DISCHARGE OF LIABILITY ON SECURITIES.  When (i) the 
Company delivers to the Trustee all outstanding Securities (other than 
Securities replaced pursuant to Section 2.07) for cancellation or (ii) all 
outstanding Securities have become due and payable and the Company deposits 
with the Trustee cash or, if expressly permitted by the terms hereof, 
securities sufficient to pay at Stated Maturity the Principal Amount of all 
outstanding Securities (other than Securities replaced pursuant to Section 
2.07), and if in either case the Company pays all other sums payable 
hereunder by the Company (including, without limitation, sums payable by 
delivery of shares of Common Stock pursuant to Section 3.08), then this 
Indenture shall, subject to Section 7.06, cease to be of further effect.  The 
Trustee shall join in the execution of a document prepared by the Company 
acknowledging satisfaction and discharge of this Indenture on demand of the 
Company accompanied by an Officers' Certificate and Opinion of Counsel and at 
the cost and expense of the Company.

     SECTION 8.02.  REPAYMENT TO THE COMPANY.  The Trustee and the Paying 
Agent shall return to the Company upon written request any money or 
securities held by them for the payment of any amount with respect to the 
Securities that remains unclaimed for two years; PROVIDED, HOWEVER, that at 
the Company's written request, the Trustee or such Paying Agent, before being 
required to make any such return, shall, at the expense of the Company, cause 
to be published once in THE WALL STREET JOURNAL or another daily newspaper of 
national circulation or mail to each such Holder notice that such money or 
securities remains unclaimed and that, after a date specified therein, which 
shall not be less than 30 days from the date of such mailing, any unclaimed 
money or securities then remaining will be returned to the Company.  After 
return to the Company, Holders entitled to the money or securities must look 
to the Company for payment as general creditors unless an applicable 
abandoned property law designates another person, and the Trustee and the 
Paying Agent shall have no further liability with respect to such money or 
securities for that period commencing after the return thereof.

                                       45



                                      ARTICLE 9
                                           
                                      AMENDMENTS


     SECTION 9.01.  WITHOUT CONSENT OF HOLDERS.  The Company and the Trustee 
may amend this Indenture or the Securities without the consent of any 
Securityholder:

          (1) to cure any ambiguity, omission, defect or inconsistency;
     PROVIDED, HOWEVER, that such amendment does not materially adversely affect
     the rights of any Securityholder;

          (2) to comply with Article 5 or Section 10.14;

          (3) to provide for uncertificated Securities in addition to or in
     place of certificated Securities so long as such uncertificated Securities
     are in registered form for purposes of the Internal Revenue Code of 1986,
     as amended;

          (4) to make any change that does not adversely affect the rights of
     any Securityholder;

          (5) to add to the covenants or obligations of the Company hereunder,
     for the benefit of the Securityholders, or to surrender any right, power or
     option herein conferred upon the Company; or

          (6) to make any change to comply with the TIA.

     SECTION 9.02.  WITH CONSENT OF HOLDERS.  With the written consent of the 
Holders of at least a majority in aggregate Principal Amount of the 
Securities at the time outstanding, the Company and the Trustee may amend 
this Indenture or the Securities.  However, without the consent of each 
Securityholder affected, an amendment or supplement to this Indenture or the 
Securities may not:

          (1) make any change to the Principal Amount of Securities whose
     Holders must consent to an amendment;

          (2) make any change to the rate of accrual in connection with Original
     Issue Discount, reduce the rate of interest referred to in paragraph 1 of
     the Securities or extend the time for payment of accrued Original Issue
     Discount or interest, if any, on any Security;

          (3) reduce the Principal Amount or the Issue Price of or extend the
     Stated Maturity of any Security;

                                      46



          (4) reduce the amount of cash payable in respect of conversion upon
     the Company's election to pay cash with respect thereto, the Redemption
     Price, Purchase Price or Change in Control Purchase Price of any Security
     or extend the date on which the Purchase Price or Change in Control
     Purchase Price of any Security is payable;

          (5) make any Security payable in money or securities other than that
     stated in the Security;

          (6) make any change in Section 6.04 or this Section 9.02, except to
     increase any percentage referred to therein, or make any change in Section
     6.07;

          (7) make any change that adversely affects the right to convert any
     Security (including the right to receive cash in lieu of Common Stock
     except as set forth in Section 9.01(4));

          (8) make any change that adversely affects the right to require the
     Company to purchase the Securities in accordance with the terms thereof and
     this Indenture (including the right to receive cash if the Company has
     elected to pay cash upon such purchase);

          (9) make any change to the provisions of this Indenture relating to
     the purchase of Securities at the option of the Holder pursuant to Section
     3.08 or 3.09 which change would result in a violation of applicable federal
     or state securities laws (including positions of the SEC under applicable
     no-action letters), whether as a result of the exercise or performance of
     any rights or obligations under such provisions or otherwise; or

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

     It shall not be necessary for the consent of the Holders under this 
Section 9.02 to approve the particular form of any proposed amendment, but it 
shall be sufficient if such consent approves the substance thereof.

     After an amendment under this Section 9.02 becomes effective, the 
Company shall mail to each Holder a notice briefly describing the amendment.

     SECTION 9.03.  COMPLIANCE WITH TRUST INDENTURE ACT.  Every supplemental 
indenture executed pursuant to this Article shall comply with the TIA as then 
in effect.

     SECTION 9.04.  REVOCATION AND EFFECT OF CONSENTS, WAIVERS AND ACTIONS. 
Until an amendment or waiver becomes effective, a consent to it or any other 
action by a Holder of a Security hereunder is a continuing consent by the 
Holder and every subsequent Holder of that Security or

                                       47



portion of the Security that evidences the same obligation as the consenting 
Holder's Security, even if notation of the consent, waiver or action is not 
made on the Security.  However, any such Holder or subsequent Holder may 
revoke the consent, waiver or action as to such Holder's Security or portion 
of the Security if the Trustee receives the notice of revocation before the 
date the amendment, waiver or action becomes effective.  After an amendment, 
waiver or action becomes effective, it shall bind every Securityholder, 
except as provided in Section 9.02.

     SECTION 9.05.  NOTATION ON OR EXCHANGE OF SECURITIES.  Securities 
authenticated and delivered after the execution of any supplemental indenture 
pursuant to this Article may, and shall if required by the Trustee, bear a 
notation in form approved by the Trustee as to any matter provided for in 
such supplemental indenture.  If the Company shall so determine, new 
Securities so modified as to conform, in the opinion of the Trustee and the 
Company, to any such supplemental indenture may be prepared and executed by 
the Company and authenticated and delivered by the Trustee in exchange for 
outstanding Securities.

     SECTION 9.06.  TRUSTEE TO SIGN SUPPLEMENTAL INDENTURES.  The Trustee 
shall sign any supplemental indenture authorized pursuant to this Article 9 
if the amendment does not adversely affect the rights, duties, liabilities or 
immunities of the Trustee.  If it does, the Trustee may, but need not, sign 
it. In signing such amendment the Trustee shall be entitled to receive, and 
(subject to the provisions of Section 7.01) shall be fully protected in 
relying upon, an Officers' Certificate and an Opinion of Counsel stating that 
such amendment is authorized or permitted by this Indenture.

     SECTION 9.07.  EFFECT OF SUPPLEMENTAL INDENTURES.  Upon the execution of 
any supplemental indenture under this Article, this Indenture shall be 
modified in accordance therewith, and such supplemental indenture shall form 
a part of this Indenture for all purposes; and every Holder of Securities 
theretofore or thereafter authenticated and delivered hereunder shall be 
bound thereby.

                                      ARTICLE 10
                                           
                                      CONVERSION


     SECTION 10.01.  CONVERSION PRIVILEGE.  A Holder of a Security may 
convert such Security into Common Stock at any time during the period stated 
in paragraph 8 of the Securities.  The number of shares of Common Stock 
issuable upon conversion of a Security per $1,000 of Principal Amount thereof 
(the "CONVERSION RATE") shall be that set forth in paragraph 8 in the 
Securities, subject to adjustment as herein set forth.

                                      48



     A Holder may convert a portion of the Principal Amount of a Security if 
the portion is $1,000 or an integral multiple of $1,000. Provisions of this 
Indenture that apply to conversion of all of a Security also apply to 
conversion of a portion of a Security.

     "AVERAGE SALE PRICE" means the average of the Sale Prices of the Common 
Stock for the shorter of

       (i) 30 consecutive Trading Days ending on the last full Trading Day
       prior to the Time of Determination with respect to the rights,
       options, warrants or distribution in respect of which the Average 
       Sale Price is being calculated, or

       (ii) the period (x) commencing on the date next succeeding the first
       public announcement of (a) the issuance of rights, options or warrants
       or (b) the distribution, in each case, in respect of which the Average
       Sale Price is being calculated and (y) proceeding through the last
       full trading day prior to the Time of Determination with respect to
       the rights, warrants or distribution in respect of which the Average
       Sale Price is being calculated, or

       (iii) the period, if any, (x) commencing on the date next succeeding
       the Ex-Dividend Time with respect to the next preceding (a) issuance
       of rights, warrants, or options or (b) distribution, in each case, for
       which an adjustment is required by the provisions of Section 10.06(4),
       10.07 or 10.08 and (y) proceeding through the last full Trading Day
       prior to the Time of Determination with respect to the rights,
       warrants, or options or distribution in respect of which the Average
       Sale Price is being calculated.

     If the Ex-Dividend Time (or in the case of a subdivision, combination or 
reclassification, the effective date with respect thereto) with respect to a 
dividend, subdivision, combination or reclassification to which Section 
10.06(1), (2), (3) or (5) applies occurs during the period applicable for 
calculating "Average Sale Price" pursuant to the definition in the preceding 
sentence, "Average Sale Price" shall be calculated for such period in a 
manner determined by the Board of Directors to reflect the impact of such 
dividend, subdivision, combination or reclassification on the Sale Price of 
the Common Stock during such period.

     "TIME OF DETERMINATION" means the time and date of the earlier of (i) 
the determination of stockholders entitled to receive rights, warrants, or 
options or a distribution, in each case, to which Sections 10.07 and 10.08 
apply and (ii) the time ("EX-DIVIDEND TIME") immediately prior to the 
commencement of "ex-dividend" trading for such rights, options, warrants or 
distribution on the New York Stock Exchange or such other national or 
regional exchange or market on which the Common Stock is then listed or 
quoted.

                                      49



     SECTION 10.02.  CONVERSION PROCEDURE.  To convert a Security a Holder 
must satisfy the requirements in paragraph 8 of the Securities.  The date on 
which the Holder satisfies all those requirements is the conversion date (the 
"CONVERSION DATE").  The Company shall deliver to the Holder no later than 
the seventh Business Day following the Conversion Date, through the 
Conversion Agent, a certificate for the number of full shares of Common Stock 
issuable upon the conversion and cash in lieu of any fractional share 
determined pursuant to Section 10.03.

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

     Holders may surrender a Security for conversion by means of book entry 
delivery in accordance with paragraph 8 of the Securities and the regulations 
of the applicable book entry facility.

     No payment or adjustment will be made for dividends on any Common Stock 
except as provided in this Article 10.  On conversion of a Security, that 
portion of accrued Original Issue Discount attributable to the period from 
the Issue Date to the Conversion Date with respect to the converted Security 
shall not be cancelled, extinguished or forfeited, but rather shall be deemed 
to be paid in full to the Holder thereof through delivery of the Common Stock 
(together with the cash payment, if any, in lieu of fractional shares) in 
exchange for the Security being converted pursuant to the provisions hereof; 
and the fair market value of such shares of Common Stock (together with any 
such cash payment in lieu of any fractional shares of Common Stock) shall be 
treated as issued, to the extent thereof, first in exchange for Original 
Issue Discount accrued through the Conversion Date, and the balance, if any, 
of such fair market value of such shares of Common Stock (and any such cash 
payment) shall be treated as issued in exchange for the Issue Price of the 
Security being converted pursuant to the provisions hereof.

     If the Holder converts more than one Security at the same time, the 
number of shares of Common Stock issuable upon the conversion shall be 
computed based on the total Principal Amount of the Securities converted.

                                      50



     Upon surrender of a Security that is converted in part, the Company 
shall execute, and the Trustee shall authenticate and deliver to the Holder, 
a new Security in an authorized denomination equal in Principal Amount to the 
unconverted portion of the Security surrendered.

     If the last day on which a Security may be converted is a Legal Holiday 
in a place where the Conversion Agent is located, the Security may be 
surrendered to such Conversion Agent on the next succeeding day that is not a 
Legal Holiday.

     SECTION 10.03.  FRACTIONAL SHARES.  The Company will not issue a 
fractional share of Common Stock upon conversion of a Security.  Instead, the 
Company will deliver cash for the current market value of the fractional 
share.  The current market value of a fractional share shall be determined to 
the nearest 1/1,000th of a share by multiplying the Sale Price, on the last 
Trading Day prior to the Conversion Date, of a full share by the fractional 
amount and rounding the product to the nearest whole cent.

     SECTION 10.04.  TAXES ON CONVERSION.  If a Holder converts a Security, 
the Company shall pay any documentary, stamp or similar issue or transfer tax 
due on the issue of shares of Common Stock upon such conversion.  However, 
the Holder shall pay any such tax which is due because the Holder requests 
the shares to be issued in a name other than the Holder's name.  The 
Conversion Agent may refuse to deliver the certificates representing the 
Common Stock being issued in a name other than the Holder's name until the 
Conversion Agent receives a sum sufficient to pay any tax which will be due, 
as set forth in an Officers' Certificate, because the shares are to be issued 
in a name other than the Holder's name.  Nothing herein shall preclude any 
tax withholding required by law or regulations.

     SECTION 10.05.  COMPANY TO PROVIDE STOCK.  The Company shall, prior to 
issuance of any Securities hereunder, and from time to time as may be 
necessary, reserve out of its authorized but unissued Common Stock a 
sufficient number of shares of Common Stock to permit the conversion of the 
Securities for shares of Common Stock.

     All shares of Common Stock delivered upon conversion of the Securities 
shall be newly issued shares or treasury shares, shall be duly and validly 
issued and fully paid and nonassessable and shall be free from preemptive 
rights and free of any lien or adverse claim.

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

                                        51



     SECTION 10.06.  ADJUSTMENT FOR CHANGE IN CAPITAL STOCK.  If, after the
Issue Date, the Company:

          (1) pays a dividend or makes a distribution on its Common Stock in
     shares of its Common Stock;

          (2) subdivides its outstanding shares of Common Stock into a greater
     number of shares;

          (3) combines its outstanding shares of Common Stock into a smaller
     number of shares;

          (4) pays a dividend or makes a distribution on its Common Stock in
     shares of its Capital Stock (other than Common Stock or rights, warrants or
     options for its Capital Stock); or

          (5) issues by reclassification of its Common Stock any shares of its
     Capital Stock (other than rights, warrants or options for its Capital
     Stock),

then the conversion privilege and the Conversion Rate in effect immediately 
prior to such action shall be adjusted so that the Holder of a Security 
thereafter converted may receive the number of shares or other units of 
Capital Stock of the Company which such Holder would have owned immediately 
following such action if such Holder had converted the Security immediately 
prior to such action.

     The adjustment shall become effective immediately after the record date 
in the case of a dividend or distribution and immediately after the effective 
date in the case of a subdivision, combination or reclassification.

     If after an adjustment a Holder of a Security upon conversion of such 
Security may receive shares or other units of two or more classes or series 
of Capital Stock of the Company, the Conversion Rate shall thereafter be 
subject to adjustment upon the occurrence of an action taken with respect to 
any such class or series of Capital Stock as is contemplated by this Article 
10 with respect to the Common Stock, on terms comparable to those applicable 
to Common Stock in this Article 10.

     SECTION 10.07.  ADJUSTMENT FOR RIGHTS ISSUE.  If, after the Issue Date, 
the Company distributes any rights, warrants or options to all holders of its 
Common Stock entitling them, for a period expiring within 60 days after the 
record date for such distribution, to purchase shares of Common Stock at a 
price per share less than the Sale Price as of the Time of Determination, the 
Conversion Rate shall be adjusted in accordance with the formula:

                                      52




                                 (0 + N)   
                                -----------
                    R' = R  x   0 + (N X P)
                                     -----
                                       M

where:

     R'= the adjusted Conversion Rate.

     R = the current Conversion Rate.

     0 = the number of shares of Common Stock outstanding on the record date
         for the distribution.

     N = the number of additional shares of Common Stock offered pursuant to
         the distribution.

     P = the offering price per share of such additional shares.

     M = the Average Sale Price, MINUS, in the case of (i) a distribution to
         which Section 10.06(4) applies or (ii) a distribution to which Section
         10.08 applies, for which, in each case, (x) the record date shall
         occur on or before the record date for the distribution to which this
         Section 10.07 applies and (y) the Ex-Dividend Time shall occur on or
         after the date of the Time of Determination for the distribution to
         which this Section 10.07 applies, the fair market value (on the record
         date for the distribution to which this Section 10.07 applies) of:

                    (1)  the Capital Stock of the Company distributed in
               respect of each share of Common Stock in such Section
               10.06(4) distribution, and

                    (2)  the assets of the Company or debt securities or
               any rights, warrants or options to purchase securities of
               the Company distributed in respect of each share of Common
               Stock in such Section 10.08 distribution.

The Board of Directors shall determine fair market values for the purposes of
this Section 10.07.

     The adjustment shall become effective immediately after the record date 
for the determination of shareholders entitled to receive the rights, 
warrants or options to which this Section 10.07 applies.  

                                      53




     No adjustment shall be made under this Section 10.07 if the application 
of the formula stated above in this Section 10.07 would result in value of R' 
that is equal to or less than the value of R.

     SECTION 10.08.  ADJUSTMENT FOR OTHER DISTRIBUTIONS.  If, after the Issue 
Date, the Company distributes to all holders of its Common Stock any of its 
assets or debt securities or any rights, warrants or options to purchase 
securities of the Company (including securities or cash, but excluding (x) 
distributions of Capital Stock referred to in Section 10.06 and distributions 
of rights, warrants or options referred to in Section 10.07 and (y) cash 
dividends or other cash distributions that are paid out of consolidated 
current net income or earnings retained in the business as shown on the books 
of the Company unless such cash dividends or other cash distributions are 
Extraordinary Cash Dividends (as defined below)), the Conversion Rate shall 
be adjusted, subject to the provisions of the last paragraph of this Section 
10.08, in accordance with the formula:

                                   M 
                                  ---
                         R' = R x M-F

where:

     R' = the adjusted Conversion Rate.

     R  = the current Conversion Rate.

     M  = the Average Sale Price, MINUS, in the case of a distribution to which
          Section 10.06(4) applies for which (i) the record date shall occur on
          or before the record date for the distribution to which this Section
          10.08 applies and (ii) the Ex-Dividend Time shall occur on or after
          the date of the Time of Determination for the distribution to which
          this Section 10.08 applies, the fair market value (on the record date
          for the distribution to which this Section 10.08 applies) of any
          Capital Stock of the Company distributed in respect of each share of
          Common Stock in such Section 10.06(4) distribution.

     F  = the fair market value (on the record date for the distribution to
          which this Section 10.08 applies) of the assets, securities, rights,
          warrants or options to be distributed in respect of each share of
          Common Stock in the distribution to which this Section 10.08 is being
          applied (including, in the case of cash dividends or other cash
          distributions giving rise to an adjustment, all such cash distributed
          concurrently).

The Board of Directors shall determine fair market values for the purpose of
this Section 10.08.

     The adjustment shall become effective immediately after the record date 
for the determination of shareholders entitled to receive the distribution to 
which this Section 10.08 applies.

                                       54



     For purposes of this Section 10.08, the term "EXTRAORDINARY CASH DIVIDEND"
shall mean any cash dividend with respect to the Common Stock the amount of
which, together with the aggregate amount of cash dividends on the Common Stock
to be aggregated with such cash dividend in accordance with the provisions of
this paragraph, equals or exceeds the threshold percentages set forth in items
(i) or (ii) below:

          (i) If, upon the date prior to the Ex-Dividend Time with respect to a
          cash dividend on the Common Stock, the aggregate amount of such cash
          dividend together with the amounts of all cash dividends on the Common
          Stock with Ex-Dividend Times occurring in the eighty-five (85)
          consecutive day period ending on the date prior to the Ex-Dividend
          Time with respect to the cash dividend to which this provision is
          being applied equals or exceeds 12.5% of the average of the Sale
          Prices during the period beginning on the date after the first such
          Ex-Dividend Time in such period and ending on the date prior to the
          Ex-Dividend Time with respect to the cash dividend to which this
          provision is being applied (except that if no other cash dividend has
          had an Ex-Dividend Time occurring in such period, the period for
          calculating the average of the Sale Prices shall be the period
          commencing 85 days prior to the date prior to the Ex-Dividend Time
          with respect to the cash dividend to which this provision is being
          applied), such cash dividend together with each other cash dividend
          with an Ex-Dividend Time occurring in such 85-day period shall be
          deemed to be an Extraordinary Cash Dividend and for purposes of
          applying the formula set forth above in this Section 10.08, the value
          of "F" shall be equal to (w) the aggregate amount of such cash
          dividend together with the amounts of the other cash dividends with
          Ex-Dividend Times occurring in such period MINUS (x) the aggregate
          amount of such other cash dividends with Ex-Dividend Times occurring
          in such period for which a prior adjustment in the Conversion Rate was
          previously made under this Section 10.08.

          (ii) If upon the date prior to the Ex-Dividend Time with respect to a
          cash dividend on the Common Stock, the aggregate amount of such cash
          dividend, together with the amounts of all cash dividends on the
          Common Stock with Ex-Dividend Times occurring in the 365-consecutive-
          day period ending on the date prior to the Ex-Dividend Time with
          respect to the cash dividend to which this provision is being applied
          equals or exceeds 25% of the average of the Sale Prices during the
          period beginning on the date after the first such Ex-Dividend Time in
          such period and ending on the date prior to the Ex-Dividend Time with
          respect to the cash dividend to which this provision is being applied
          (except that if no other cash dividend has had an Ex-Dividend Time
          occurring in such period, the period for calculating the average of
          the Sale Prices shall be the period commencing 365 days prior to the
          date prior to the Ex-Dividend Time with respect to the cash dividend
          to which this provision is being applied), such cash dividend together
          with each other cash dividend

                                       55



          with an Ex-Dividend Time occurring in such 365-day period shall 
          be deemed to be an Extraordinary Cash Dividend and for purposes 
          of applying the formula set forth above in this Section 10.08, 
          the value of "F" shall be equal to (y) the aggregate amount of 
          such cash dividend together with amounts of the other cash 
          dividends with Ex-Dividend Times occurring in such period MINUS 
          (z) the aggregate amount of such other cash dividends with 
          Ex-Dividend Times occurring in such period for which a prior 
          adjustment in the Conversion Rate was previously made under 
          this Section 10.08.

     In making the determinations required by items (i) and (ii) above, the 
amount of cash dividends paid on a per share basis and the average of the 
Sale Prices, in each case during the period specified in items (i) and (ii) 
above, as applicable, shall be appropriately adjusted to reflect the 
occurrence during such period of any event described in Section 10.06

     In the event that, with respect to any distribution to which this 
Section 10.08 would otherwise apply, the difference "M-F" as defined in the 
above formula is less than $1.00 or "F" is greater than "M", then the 
adjustment provided by this Section 10.08 shall not be made and in lieu 
thereof the provisions of Section 10.14 shall apply to such distribution.

     SECTION 10.09.  WHEN ADJUSTMENT MAY BE DEFERRED.  No adjustment in the 
Conversion Rate need be made unless the adjustment would require an increase 
or decrease of at least 1% (E.G., if the Conversion Rate is 4, an increase or 
decrease of .04 (1% of 4)) in the Conversion Rate.  Any adjustments that are 
not made shall be carried forward and taken into account in any subsequent 
adjustment.

     All calculations under this Article 10 shall be made to the nearest cent 
or to the nearest 1/1,000th of a share, as the case may be, with one-half of 
a cent and 5/10,000ths of a share being rounded upwards.

     SECTION 10.10. WHEN NO ADJUSTMENT REQUIRED.  No adjustment need be made 
for a transaction referred to in Section 10.06, 10.07, 10.08 or 10.14 if 
Securityholders are to participate in the transaction on a basis and with 
notice that the Board of Directors determines to be fair and appropriate in 
light of the basis and notice on which holders of Common Stock participate in 
the transaction.  

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

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

                                      56



     No adjustment need be made unless such adjustment, together with any 
other adjustments similarly deferred equals at least 1% of the then current 
Conversion Rate.

     To the extent the Securities become convertible into cash pursuant to 
the terms of Section 10.08 or 10.14, no adjustment need be made thereafter as 
to the cash.  Interest will not accrue on the cash.

     Notwithstanding any provision to the contrary in this Indenture, no 
adjustment shall be made in the Conversion Rate to the extent, but only to 
the extent, such adjustment results in the following quotient being less than 
the par value of the Common Stock:  (i) the Issue Price plus accrued Original 
Issue Discount as of the date such adjustment would otherwise be effective 
divided by (ii) the Conversion Rate as so adjusted.

     SECTION 10.11. NOTICE OF ADJUSTMENT.  Whenever the Conversion Rate is 
adjusted, the Company shall file with the Trustee and the Conversion Agent a 
notice of such adjustment and a certificate from the Company's independent 
public accountants briefly stating the facts requiring the adjustment and the 
manner of computing it.  The Conversion Agent will promptly mail such notice 
to Securityholders at the Company's expense.  The certificate shall be 
conclusive evidence that the adjustment is correct.  Neither the Trustee nor 
any Conversion Agent shall be under any duty or responsibility with respect 
to any such certificate except to exhibit the same to any Holder desiring 
inspection thereof.

     SECTION 10.12. VOLUNTARY INCREASE.  The Company from time to time may 
increase the Conversion Rate by any amount and for any period of time 
(PROVIDED, that such period is not less than 20 Business Days).  Whenever the 
Conversion Rate is increased, the Company shall mail to Securityholders and 
file with the Trustee and the Conversion Agent a notice of the increase.  The 
Company shall mail the notice at least 15 days before the date the increased 
Conversion Rate takes effect.  The notice shall state the increased 
Conversion Rate and the period it will be in effect.

     A voluntary increase of the Conversion Rate does not change or adjust 
the Conversion Rate otherwise in effect for purposes of Sections 10.06, 10.07 
or 10.08.

     SECTION 10.13. NOTICE OF CERTAIN TRANSACTIONS.  If:

          (1) the Company takes any action that would require an adjustment in
     the Conversion Rate pursuant to Section 10.06, 10.07 or 10.08 (unless no
     adjustment is to occur pursuant to Section 10.10); or

          (2) the Company takes any action that would require a supplemental
     indenture pursuant to Section 10.14; or

                                       57


          (3) there is a liquidation or dissolution of the Company;

then the Company shall mail to Securityholders and file with the Trustee and 
the Conversion Agent a notice stating the proposed record date for a dividend 
or distribution of the proposed effective date of a subdivision, combination, 
reclassification, consolidation, merger, binding share exchange, transfer, 
liquidation or dissolution.  The Company shall file and mail the notice at 
least 15 days before such date.  Failure to file or mail the notice or any 
defect in it shall not affect the validity of the transaction.

     SECTION 10.14. REORGANIZATION OF COMPANY; SPECIAL DISTRIBUTIONS.  If the 
Company is a party to a transaction subject to Section 5.01 (other than a 
sale of all or substantially all of the assets of the Company in a 
transaction in which the holders of Common Stock immediately prior to such 
transaction do not receive securities, cash or other assets of the Company or 
any other person) or a merger or binding share exchange which reclassifies or 
changes its outstanding Common Stock, the person obligated to deliver 
securities, cash or other assets upon conversion of Securities shall enter 
into a supplemental indenture.  If the issuer of securities deliverable upon 
conversion of Securities is an Affiliate of the successor Company, that 
issuer shall join in the supplemental indenture.

     The supplemental indenture shall provide that the Holder of a Security 
may convert it into the kind and amount of securities, cash or other assets 
which such Holder would have received immediately after the consolidation, 
merger, binding share exchange or transfer if such Holder had converted the 
Security immediately before the effective date of the transaction, assuming 
(to the extent applicable) that such Holder (i) was not a constituent person 
or an Affiliate of a constituent person to such transaction; (ii) made no 
election with respect thereto; and (iii) was treated alike with the plurality 
of non-electing Holders.  The supplemental indenture shall provide for 
adjustments which shall be as nearly equivalent as may be practical to the 
adjustments provided for in this Article 10.  The successor Company shall 
mail to Securityholders a notice briefly describing the supplemental 
indenture.

     If this Section applies, neither Section 10.06 nor 10.07 applies.

     If the Company makes a distribution to all holders of its Common Stock 
of any of its assets, or debt securities or any rights, warrants or options 
to purchase securities of the Company that, but for the provisions of the 
last paragraph of Section 10.08, would otherwise result in an adjustment in 
the Conversion Rate pursuant to the provisions of Section 10.08, then, from 
and after the record date for determining the holders of Common Stock 
entitled to receive the distribution, a Holder of a Security that converts 
such Security in accordance with the provisions of this Indenture shall upon 
such conversion be entitled to receive, in addition to the shares of Common 
Stock into which the Security is convertible, the kind and amount of 
securities, cash or other assets comprising the distribution that such Holder 
would have received if such Holder had converted the Security

                                      58


immediately prior to the record date for determining the holders of Common 
Stock entitled to receive the distribution.

     SECTION 10.15. COMPANY DETERMINATION FINAL.  Any determination that the 
Company or the Board of Directors must make pursuant to this Article 10 is 
conclusive.

     SECTION 10.16. TRUSTEE'S ADJUSTMENT DISCLAIMER.  The Trustee has no duty 
to determine when an adjustment under this Article 10 should be made, how it 
should be made or what it should be.  The Trustee has no duty to determine 
whether a supplemental indenture under Section 10.14 need be entered into or 
whether any provisions of any supplemental indenture are correct.  The 
Trustee shall not be accountable for and makes no representation as to the 
validity or value of any securities or assets issued upon conversion of 
Securities.  The Trustee shall not be responsible for the Company's failure 
to comply with this Article 10. Each Conversion Agent (other than the Company 
or an Affiliate of the Company) shall have the same protection under this 
Section 10.16 as the Trustee.

     SECTION 10.17. SIMULTANEOUS ADJUSTMENTS.  If this Article 10 requires 
adjustments to the Conversion Rate under more than one of Sections 10.06(4), 
10.07 or 10.08, and the record dates for the distributions giving rise to 
such adjustments shall occur on the same date, then such adjustments shall be 
made by applying, first, the provisions of Section 10.06, second, the 
provisions of Section 10.08 and, third, the provisions of Section 10.07.

     SECTION 10.18. SUCCESSIVE ADJUSTMENTS.  After an adjustment to the 
Conversion Rate under this Article 10, any subsequent event requiring an 
adjustment under this Article 10 shall cause an adjustment to the Conversion 
Rate as so adjusted.


                                     ARTICLE 11

                                   MISCELLANEOUS


     SECTION 11.01  TRUST INDENTURE ACT CONTROLS.  If any provision of this 
Indenture limits, qualifies or conflicts with another provision which is

1.   INTEREST

     This Security shall not bear interest except as specified in this 
paragraph.  If the Principal Amount hereof or any portion of such Principal 
Amount is not paid when due (whether upon acceleration pursuant to Section 
6.02 of the Indenture, upon the date set for payment of the Redemption Price 
pursuant to paragraph 5 hereof, upon the date set for payment of a Purchase 
Price or Change in Control Purchase Price pursuant to paragraph 6 hereof or 
upon the Stated Maturity of this Security) or if shares of Common Stock (or 
cash in lieu of fractional shares) in respect of a conversion of this 
Security in accordance with the terms of Article 10 of the Indenture is not 
delivered when due, then in each such case the overdue amount shall bear 
interest at the rate of [     ]% per annum, compounded semiannually (to the 
extent that the payment of such interest shall be legally enforceable), which 
interest shall accrue from the date such overdue amount was due to the date 
payment of such amount, including interest thereon, has been made or duly 
provided for.  All such interest shall be payable on demand.

     Original Issue Discount (the difference between the Issue Price and the 
Principal Amount of the Security), in the period during which a Security 
remains outstanding, shall accrue at [     ]% per annum, on a semiannual bond 
equivalent basis using a 360-day year composed of twelve 30-day months, 
commencing on the Issue Date of this Security, and cease to accrue on the 
earlier of (a) the date on which the Principal Amount at Stated Maturity 
hereof or any portion of such Principal Amount at Stated Maturity becomes due 
and payable and (b) any Redemption Date, Conversion Date, Change in Control 
Purchase Date, Purchase Date or other date on which such Original Issue 
Discount shall cease to accrue in

2.   METHOD OF PAYMENT

    Subject to the terms and conditions of the Indenture, Jacor 
Communications, Inc. (the "Company") will make payments in respect of the 
Securities to the persons who are registered Holders of Securities at the 
close of business on the Business Day preceding the Redemption Date or Stated 
Maturity, as the case may be, or at the close of business on a Purchase Date, 
Change in Control Purchase Date or Conversion Date, as the case may be.  
Holders must surrender Securities to a Paying Agent to collect such payments 
in respect of the Securities.  The Company will pay cash amounts in money of 
The United States of America that at the time of payment is legal tender for 
payment of public and private debts. However, the Company may make such cash 
payments in respect of a certificated Security, if applicable, by check 
payable in such money; provided that payment by wire transfer of immediately 
available funds will be required with respect to payments in respect of all 
Global Securities and all other Securities the Holders of which shall have 
provided written wire transfer instructions to the Company or the Paying 
Agent five days before the payment date.

3.   PAYING AGENT, CONVERSION AGENT AND REGISTRAR

     Initially, The Bank of New York, a New York banking corporation, as 
trustee (the "Trustee"), will act as Paying Agent, Conversion Agent and 
Registrar.  The Company may appoint and change any Paying Agent, Conversion 
Agent, Registrar or co-registrar, upon notice to the Trustee and the Holders. 
 The Company or any of its Subsidiaries or any of their Affiliates may act as 
Paying Agent, Conversion Agent, Registrar or co-registrar.

4.   INDENTURE

     The Company issued the Securities under an Indenture, dated as of 
January [  ], 1998 (the "Indenture"), between the Company and the Trustee.  
The terms of the Securities include those stated in the Indenture and those 
made part of the Indenture by reference to the Trust Indenture Act of 1939, 
as amended by the Trust Indenture Reform Act of 1990, and, as in effect on 
the date of the Indenture (the "TIA"), except as provided in Section 9.03 of 
the Indenture. Capitalized terms used herein or on the face hereof and not 
defined herein have the meanings ascribed thereto in the Indenture.  The 
Securities are subject to all such terms, and Securityholders are referred to 
the Indenture and the TIA for a statement of those terms.

     The Securities are general unsecured obligations of the Company limited 
to the aggregate Principal Amount at Stated Maturity specified in Section 
2.02 of the Indenture (subject to Section 2.07 of the

Indenture).  The Indenture does not limit other indebtedness of the Company, 
secured or unsecured.

5.   REDEMPTION AT THE OPTION OF THE COMPANY

     No sinking fund is provided for the Securities.  The Securities are 
redeemable as a whole, or from time to time in part, at any time at the 
option of the Company at the Redemption Prices set forth below, PROVIDED,

Principal Amount at Stated Maturity on the dates shown below and at Stated 
Maturity, which prices reflect accrued Original Issue Discount calculated to

Issue Discount accrued from and including the next preceding date in the

become obligated to purchase, at the option of the Holder, the Securities 
held by such Holder on the following Purchase Dates and at the following 
Purchase Prices per $1,000 Principal Amount at Stated Maturity of such 
Securities, upon delivery of a Purchase Notice containing the information set 
forth in the Indenture, at any time from

- --------------------------

                                       A-6



the opening of business on the date that is 20 Business Days prior to such 
Purchase Date until the close of business on such Purchase Date and upon 
delivery of the Securities to the Paying Agent by the Holder as set forth in 
the Indenture.  Such Purchase Price (equal to the Issue Price plus accrued 
Original Issue Discount through such Purchase Date) may be paid, at the 
option of the Company, in cash or by the issuance and delivery of shares of 
Common Stock of the Company, or in any combination thereof.

     PURCHASE DATE            PURCHASE PRICE
     ---------------------    --------------
     January [  ], 20[  ]     $   
     January [  ], 20[  ]     $   

     Subject to the terms and conditions of the Indenture, if any Change in 
Control occurs on or prior to January [  ], 20[  ], the Company shall, at the 
option of the Holder, purchase all Securities for which a Change in Control 
Purchase Notice shall have been delivered as provided in the Indenture and 
not withdrawn, on the date that is 35 Business Days after the occurrence of 
such Change in Control, for a Change in Control Purchase Price equal to the 
Issue Price plus accrued Original Issue Discount through the Change in 
Control Purchase Date, which Change in Control Purchase Price shall be paid 
in cash.  

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

    If cash sufficient to pay the Purchase Price or Change in Control 
Purchase Price of all Securities or portions thereof to be purchased as of 
the Purchase Date or the Change in Control Purchase Date, as the case may be, 
is deposited with the Paying Agent on the Business Day following the Purchase 
Date or the Change in Control Purchase Date, as the case may be, Original 
Issue Discount ceases to accrue on such Securities (or portions thereof) on 
and after such date, and the Holders thereof shall have no other rights as 
such (other than the right to receive the Purchase Price or Change in Control 
Purchase Price, as the case may be, upon surrender of such Security).

7.   NOTICE OF REDEMPTION

     Notice of redemption will be mailed at least 30 days but not more than 
60 days before the Redemption Date to each Holder of Securities to be 
redeemed at the Holder's registered address.  If money sufficient to pay the 
Redemption Price of all Securities (or portions thereof) to be redeemed on 
the Redemption Date is deposited with the Paying Agent prior to or on the 
Redemption Date, on and after such date Original Issue Discount ceases to 
accrue on such Securities or portions thereof.  Securities in denominations 
larger than $1,000 of Principal Amount may be redeemed in part but only in 
integral multiples of $1,000 of Principal Amount.

8.   CONVERSION

     Subject to the next two succeeding sentences, a Holder of a Security may 
convert it into Common Stock of the Company at any time before the close of 
business on January [  ], 20[  ]; PROVIDED, HOWEVER, that if a Security is 
called for redemption, the Holder may convert it at any time before the close 
of business on the Redemption Date.  The number of shares of Common Stock to 
be delivered upon conversion of a Security into Common Stock per $1,000 of 
Principal Amount shall be equal to the Conversion Rate.  A Security in 
respect of which a Holder has delivered a Purchase Notice or Change in 
Control Purchase Notice exercising the option of such Holder to require the 
Company to purchase such Security may be converted only if the notice of 
exercise is withdrawn in accordance with the terms of the Indenture.

    The initial Conversion Rate is [   ] shares of Common Stock per $1,000 
Principal Amount, subject to adjustment in certain events described in the 
Indenture.  The Company will deliver cash or a check in lieu of any 
fractional share of Common Stock.

    To convert a Security a Holder must (i) complete and manually sign the 
conversion notice on the back of the Security (or complete and manually sign 
a facsimile of such notice) and deliver such notice to the Conversion Agent 
(or the office or agency referred to in Section 4.05 of the Indenture), (ii) 
furnish appropriate endorsements and transfer documents if required by the 
Conversion Agent, the Company or the Trustee and (iii) pay any transfer or 
similar tax, if required.  

     If the Holder converts more than one Security at the same time, the 
number of shares of Common Stock issuable upon the conversion shall be based 
on the total Principal Amount of the Securities converted.

    A Holder may convert a portion of a Security if the Principal Amount of 
such portion is $1,000 or an integral multiple of $1,000.  No payment or 
adjustment will be made for dividends on the Common Stock except as provided 
in the Indenture.  On conversion of a Security, that portion of accrued 
Original Issue Discount attributable to the period from the Issue Date to the 
Conversion Date with respect to the converted Security shall not be 
cancelled, extinguished or forfeited, but rather shall be deemed paid in full 
to the Holder thereof through the delivery of the Common Stock in exchange 
for the Security being converted pursuant to the terms hereof; and the fair 
market value of such Common Stock (together with any cash payment in lieu of 
fractional shares of Common Stock) shall be treated as issued, to the extent 
thereof, first in exchange for Original Issue Discount accrued through the 
Conversion Date, and the balance, if any, of such fair market value of such 
shares of Common Stock (and any such cash payment) shall be treated as issued 
in exchange for the Issue Price of the Security being converted pursuant to 
the provisions hereof.

- --------------------------
TM  Trademark of Merrill Lynch & Co., Inc.

                                       A-8




    The Conversion Rate will be adjusted for dividends or distributions on 
Common Stock payable in Common Stock or other Capital Stock; subdivisions, 
combinations or certain reclassifications of Common Stock; distributions to 
all holders of Common Stock of certain rights to purchase Common Stock for a 
period expiring within 60 days at less than the Sale Price at the Time of 
Determination; and distributions to such holders of assets or debt securities 
of the Company or certain rights to purchase securities of the Company 
(excluding certain cash dividends or distributions).  However, no adjustment 
need be made if Securityholders may participate in the transaction or in 
certain other cases. The Company from time to time may voluntarily increase 
the Conversion Rate.

    If the Company is a party to a consolidation, merger or binding share 
exchange of the type specified in the Indenture, or certain transfers of all 
or substantially all of its assets to another person, or in certain other 
circumstances described in the Indenture, the right to convert a Security 
into Common Stock may be changed into a right to convert it into securities, 
cash or other assets of the Company or another person.

9.   CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION

     Any Securities called for redemption, unless surrendered for conversion 
before the close of business on the Redemption Date, may be deemed to be 
purchased from the Holders of such Securities at an amount not less than the 
Redemption Price, together with accrued interest if any, to the Redemption 
Date, by one or more investment bankers or other purchasers who may agree 
with the Company to purchase such Securities from the Holders and to make 
payment for such Securities to the Trustee in trust for such Holders.

10.   DENOMINATIONS; TRANSFER; EXCHANGE

     The Securities are in fully registered form, without coupons, in 
denominations of $1,000 of Principal Amount and integral multiples of $1,000. 
A Holder may transfer or exchange Securities in accordance with the 
Indenture. The Registrar may require a Holder, among other things, to furnish 
appropriate endorsements and transfer documents and to pay any taxes and fees 
required by law or permitted by the Indenture.  The Registrar need not 
transfer or exchange any Securities selected for redemption (except, in the 
case of a Security to be redeemed in part, the portion of the Security not to 
be redeemed) or any Securities in respect of which a Purchase Notice or 
Change in Control Purchase Notice has been given and not withdrawn (except, 
in the case of a Security to be purchased in part, the portion of the 
Security not to be purchased) or any Securities for a period of 15 days 
before a selection of Securities to be redeemed.

11.   PERSONS DEEMED OWNERS

     The registered Holder of this Security may be treated as the owner of 
this Security for all purposes.

12.   UNCLAIMED MONEY OR SECURITIES

     The Trustee and the Paying Agent shall return to the Company upon 
written request any money or securities held by them for the payment of any 
amount with respect to the Securities that remains unclaimed for two years, 
PROVIDED, HOWEVER, that at the Company's request, the Trustee or such Paying 
Agent, before being required to make any such return, shall at the expense of 
the Company cause to be published once in THE WALL STREET JOURNAL or another 
newspaper of national circulation or mail to each such Holder notice that 
such money or securities remains unclaimed and that, after a date specified 
therein, which shall not be less than 30 days from the date of such 
publication or mailing, any unclaimed money or securities then remaining will 
be returned to the Company. After return to the Company, Holders entitled to 
the money or securities must look to the Company for payment as general 
creditors unless an applicable abandoned property law designates another 
person, and the Trustee and the Paying Agent shall have no further liability 
with respect to such money or securities for that period commencing after the 
return thereof.

13.   AMENDMENT; WAIVER

     Subject to certain exceptions set forth in the Indenture, (i) the 
Indenture or the Securities may be amended with the written consent of the 
Holders of at least a majority in aggregate Principal Amount of the 
Securities at the time outstanding and (ii) certain defaults or noncompliance 
with certain provisions may be waived with the written consent of the Holders 
of a majority in aggregate Principal Amount of the Securities at the time 
outstanding.  Subject to certain exceptions set forth in the Indenture, 
without the consent of any Securityholder, the Company and the Trustee may 
amend the Indenture or the Securities to cure any ambiguity, defect or 
inconsistency, or to comply with Article 5 or Section 10.14 of the Indenture 
or to make any change that does not adversely affect the rights of any 
Securityholder.

14.   DEFAULTS AND REMEDIES

    Under the Indenture, Events of Default include (i) default in payment of 
the Principal Amount, Issue Price, accrued Original Issue Discount, 
Redemption Price, Purchase Price or Change in Control Purchase Price, as the 
case may be, in respect of the Securities when the same becomes due and 
payable; (ii) failure either to deliver shares of Common Stock (or cash in 
lieu of fractional shares) in accordance with the terms of the Indenture when 
such Common Stock (or cash in lieu of fractional shares) is required to be 
delivered following conversion of a Security and such failure is not remedied 
for a period of 10 days; (iii) failure by the Company to comply with other 
agreements in the Indenture or the Securities, subject to notice and lapse of 
time; (iv) default (A) in the payment of any principal on any debt for

Company (excluding any non-recourse debt), in an aggregate principal amount 
in excess of $10 million when due at its final maturity after giving effect 
to any applicable grace period and the holder thereof shall have taken 
affirmative action to enforce the payment thereof, or (B) in the performance 
of any term or provision of any debt for borrowed money of the Company 
(excluding any non-recourse debt) in an aggregate principal amount in excess 
of $10 million that results in such debt becoming or being declared due and 
payable prior to the date on which it would otherwise become due and payable, 
unless, in the case of either clause (A) or (B) above, (x) such acceleration 
or action to enforce payment, as the case may be, has been rescinded or 
annulled, (y) such debt has been discharged or (z) a sum sufficient to 
discharge in full such debt has been deposited in trust by or on behalf of 
the Company, in each case, within a period of 10 days after there has been 
given, by registered or certified mail, to the Company by the Trustee or to 
the Company and the Trustee by the Holders of at least 25% in principal 
amount of the Securities, a written notice specifying such default or 
defaults and stating that such notice is a "Notice of Default" hereunder; or 
(v) certain events of bankruptcy or insolvency.  If an Event of Default 
occurs and is continuing, the Trustee, or the Holders of at least 25% in 
aggregate Principal Amount of the Securities at the time outstanding, may 
declare all the Securities to be due and payable immediately.  Certain events 
of bankruptcy or insolvency are Events of Default that will result in the 
Securities becoming due and payable immediately upon the occurrence of such 
Events of Default.

    Securityholders may not enforce the Indenture or the Securities except as 
provided in the Indenture.  The Trustee may refuse to enforce the Indenture 
or the Securities unless it receives reasonable indemnity or security.  
Subject to certain limitations, Holders of a majority in aggregate Principal 
Amount of the Securities at the time outstanding may direct the Trustee in 
its exercise of any trust or power.  The Trustee may withhold from 
Securityholders notice of any continuing Default (except a Default in payment 
of amounts specified in clause (i) above) if it determines that withholding 
notice is in their interests.

15.   TRUSTEE DEALINGS WITH THE COMPANY

     Subject to certain limitations imposed by the TIA, the Trustee under the 
Indenture, in its individual or any other capacity, may become the owner or 
pledgee of Securities and may otherwise deal with and collect obligations 
owed to it by the Company or its Affiliates and may otherwise deal with the 
Company or its Affiliates with the same rights it would have if it were not 
Trustee.

16.   NO RECOURSE AGAINST OTHERS

     A director, officer, employee or stockholder, as such, of the Company 
shall not have any liability for any obligations of the Company under the 
Securities or the Indenture or for any claim based on, in respect of or by 
reason of such obligations or their creation.  By accepting a Security, each 
Securityholder waives and releases all such liability.  The waiver and 
release are part of the consideration for the issue of the Securities.
