     to distribute all assets held by it to the Trustee and account for any
     assets disbursed and the Trustee may at any time during the continuance of
     any payment Default, upon written request to a Paying Agent, require such
     Paying Agent to distribute all assets held by it to the Trustee and to
     account for any assets distributed.  Upon distribution to the Trustee of
     all assets that shall have been delivered by the Company to the Paying
     Agent, the Paying Agent (if other than the Company) shall have no further
     liability for such assets.

             SECTION 2.5  Securityholder Lists.
                          -------------------- 

             The Trustee shall preserve in as current a form as is reasonably
     practicable the most recent list available to it of the names and addresses
     of Holders.  If the Trustee is not the Registrar, the Company shall furnish
     to the Trustee on or before the tenth Business Day preceding each Interest
     Payment Date and at such other times as the Trustee may request in writing
     a list in such form and as of such date as the Trustee reasonably may
     require of the names and addresses of Holders.

                                       18


             SECTION 2.6  Transfer and Exchange.
                          --------------------- 

             When Securities are presented to the Registrar or a co-Registrar
     with a request to register the transfer of such Securities or to exchange
     such Securities for an equal principal amount of Securities of other
     authorized denominations, the Registrar or co-Registrar shall register the
     transfer or make the exchange as requested if its reasonable requirements
     for such transaction are met; provided, however, that the Securities
                                   --------  -------                     
     surrendered for transfer or exchange shall be duly endorsed or accompanied
     by a written instrument of transfer in form reasonably satisfactory to the
     Company and the Registrar or co-Registrar, duly executed by the Holder
     thereof or his attorney duly authorized in writing.  To permit
     registrations of transfers and exchanges, the Company shall execute and the
     Trustee shall authenticate Securities at the Registrar's or co-Registrar's
     request.  No service charge shall be made for any registration of transfer
     or exchange, but the Company may require payment of a sum sufficient to
     cover any transfer tax, assessments, or similar governmental charge payable
     in connection therewith (other than any such transfer taxes, assessments,
     or similar governmental charge payable upon exchanges or transfers pursuant
     to Section 2.2, 2.10, 3.7, 9.5, or 4.10).  The Registrar or co-Registrar
     shall not be required to register the transfer of or exchange of (a) any
     Security selected for redemption in whole or in part pursuant to Article
     Three, except the unredeemed portion of any Security being redeemed in
     part, or (b) any Security for a period beginning 15 Business Days before
     the mailing of a notice of an offer to repurchase pursuant to Section 4.10
     hereof or redeem Securities pursuant to Article 3 hereof and ending at the
     close of business on the day of such mailing.

             SECTION 2.7  Replacement Securities.
                          ---------------------- 

             If a mutilated Security is surrendered to the Trustee or if the
     Holder of a Security claims and submits an affidavit or other evidence,
     satisfactory to the Trustee, to the Trustee to the effect that the Security
     has been lost, destroyed or wrongfully taken, the Company shall issue and
     the Trustee shall authenticate a replacement Security if the Trustee's
     requirements are met.  If required by the Trustee or the Company, such
     Holder must provide an indemnity bond or other indemnity, sufficient in the
     judgment of both the Company and the Trustee, to protect the Company, the
     Trustee or any Agent from any

                                       19


     loss which any of them may suffer if a Security is replaced.  The Company
     may charge such Holder for its reasonable, out-of-pocket expenses in
     replacing a Security.

             Every replacement Security is an additional obligation of the
     Company.

             SECTION 2.8  Outstanding Securities.
                          ---------------------- 

             Securities outstanding at any time are all the Securities that have
     been authenticated by the Trustee except those cancelled by it, those
     delivered to it for cancellation and those described in this Section 2.8 as
     not outstanding.  A Security does not cease to be outstanding because the
     Company or an Affiliate of the Company holds the Security, except as
     provided in Section 2.9.

             If a Security is replaced pursuant to Section 2.7 (other than a
     mutilated Security surrendered for replacement), it ceases to be
     outstanding unless the Trustee receives proof satisfactory to it that the
     replaced Security is held by a bona fide purchaser.  A mutilated Security
                                    ---- ----                                 
     ceases to be outstanding upon surrender of such Security and replacement
     thereof pursuant to Section 2.7.

             If on a Redemption Date or the Stated Maturity the Paying Agent
     (other than the Company or an Affiliate of the Company) holds U.S. Legal
     Tender or U.S. Government Obligations sufficient to pay all of the
     principal and interest due on the Securities payable on that date and
     payment of the Securities called for redemption is not otherwise prohibited
     pursuant to Article Twelve hereof or otherwise, then on and after that date
     such Securities cease to be outstanding and interest on them ceases to
     accrue.

             SECTION 2.9  Treasury Securities.
                          ------------------- 

             In determining whether the Holders of the required principal amount
     of Securities have concurred in any direction, amendment, supplement,
     waiver or consent, Securities owned by the Company and Affiliates of the
     Company shall be disregarded, except that, for the purposes of determining
     whether the Trustee shall be protected in relying on any such direction,
     amendment, supplement, waiver or consent, only Securities that the

                                       20


     Trustee knows or has reason to know are so owned shall be disregarded.

             SECTION 2.10  Temporary Securities.
                           -------------------- 

             Until definitive Securities are ready for delivery, the Company may
     prepare, and the Trustee shall authenticate, temporary Securities. 
     Temporary Securities shall be substantially in the form of definitive
     Securities but may have variations that the Company reasonably and in good
     faith considers appropriate for temporary Securities.  Without unreasonable
     delay, at the time that the registration statement pursuant to the
     Registration Rights Agreement becomes effective, the Company shall prepare
     and the Trustee shall authenticate definitive Securities in exchange for
     temporary Securities.  Until so exchanged, the temporary Securities shall
     in all respects be entitled to the same benefits under this Indenture as
     permanent Securities authenticated and delivered hereunder.

             SECTION 2.11  Cancellation.
                           ------------ 

             The Company at any time may deliver Securities to the Trustee for
     cancellation.  The Registrar and the Paying Agent shall forward to the
     Trustee any Securities surrendered to them for transfer, exchange or
     payment. The Trustee, or at the direction of the Trustee, the Registrar or
     the Paying Agent (other than the Company or an Affiliate of the Company),
     and no one else, shall cancel and, at the written direction of the Company,
     shall dispose of all Securities surrendered for transfer, exchange, payment
     or cancellation.  Subject to Section 2.7, the Company may not issue new
     Securities to replace Securities it has paid or delivered to the Trustee
     for cancellation.  No Securities shall be authenticated in lieu of or in
     exchange for any Securities cancelled as provided in this Section 2.11,
     except as expressly permitted in the form of Securities and as permitted by
     this Indenture.

             SECTION 2.12  Defaulted Interest.
                           ------------------ 

             Interest on any Security which is payable, and is punctually paid
     or duly provided for, on any Interest Payment Date shall be paid to the
     person in whose name that Security (or one or more predecessor Securities)
     is registered at the close of business on the Record Date for such
     interest.

                                       21


             Any interest on any Security which is payable, but is not
     punctually paid or duly provided for, on any Interest Payment Date plus, to
     the extent lawful, any interest payable on the defaulted interest (herein
     called "Defaulted Interest") shall forthwith cease to be payable to the
     registered holder on the relevant Record Date by virtue of having been such
     Holder, and such Defaulted Interest may be paid by the Company, at its
     election in each case, as provided in clause (1) or (2) below:

                        (1)  The Company may elect to make payment of any 
         Defaulted Interest to the persons in whose names the Securities  are
         registered at the close of business on a Special Record Date for the
         payment of such Defaulted Interest, which shall be fixed in the
         following manner.  The Company shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Security
         and the date of the proposed payment, and at the same time the Company
         shall deposit with the Trustee an amount of money equal to the
         aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money when
         deposited to be held in trust for the benefit of the Persons entitled
         to such Defaulted Interest as provided in this clause (1).  Thereupon
         the Trustee shall fix a Special Record Date for the payment of such
         Defaulted Interest which shall be not more than 15 days and not less
         than 10 days prior to the date of the proposed payment and not less
         than 10 days after the receipt by the Trustee of the notice of the
         proposed payment.  The Trustee shall promptly notify the Company of
         such Special Record Date and, in the name and at the expense of the
         Company, shall cause notice of the proposed payment of such Defaulted
         Interest and the Special Record Date therefor to be mailed, first-class
         postage prepaid, to each Holder at his address as it appears in the
         security register not less than 10 days prior to such Special Record
         Date.  The Trustee may, in its discretion, in the name and at the
         expense of the Company, cause a similar notice to be published at least
         once in a newspaper, customarily published in the English language on
         each

                                       22


         Business Day and of general circulation in New York, New York, but such
         publication shall not be a condition precedent to the establishment of
         such Special Record Date.  Notice of the proposed payment of such 
         Defaulted Interest and the Special Record Date therefor having been
         mailed as aforesaid, such Defaulted Interest shall be paid to the
         persons in whose names the Securities (or their respective predecessor
         Securities) are registered on such Special Record Date and shall no
         longer be payable pursuant to the following clause (2).

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

           Subject to the foregoing provisions of this Section 2.12, each 
Security delivered under this Indenture upon transfer of or in exchange for or
in lieu of any other Security shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security.

           SECTION 2.13  Legending of the Securities; Restrictions on Transfers.
                         ------------------------------------------------------ 

        Until such time as the same is no longer a Restricted Security, each
certificate evidencing the Securities (and all Securities issued in exchange
therefor or substitution thereof) shall bear a legend in substantially the form
set forth on the form of Note set forth as Exhibit A hereto.  Prior to any
transfer or exchange of a legended Security for another Security, the Company
shall deliver an Officers' Certificate to the Trustee directing it to transfer
or exchange such Security for another legended or unlegended Security, subject
to compliance with any transfer restrictions.

                                       23


                                 ARTICLE THREE

                                  REDEMPTION

        SECTION 3.1  Right of Redemption.
                     ------------------- 

        Redemption of Securities, as permitted or required by any provision of
this Indenture, shall be made in accordance with such provision and this Article
Three.  The Securities may be redeemed in cash at the election of the Company,
as a whole or from time to time in part, at any time on or after December 15,
1998, at the Redemption Prices specified in the form of Note attached as Exhibit
A set forth therein under the caption "Redemption," in each case, including
accrued and unpaid interest, if any, to the Redemption Date.

        SECTION 3.2  Notices to Trustee.
                     ------------------ 

        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
and the principal amount of Securities to be redeemed and whether it wants the
Trustee to give notice of redemption to the Holders.

        If the Company elects to credit the principal amount of Securities to be
redeemed pursuant to Paragraph 5 of the Securities by crediting against any such
redemption Securities it has not previously delivered to the Trustee for
cancellation, it shall so notify the Trustee and deliver such Securities with
such notice.

        The Company shall give each notice to the Trustee provided for in this
Section 3.2 at least 45 days before the Redemption Date (unless a shorter notice
shall be satisfactory to the Trustee).

        SECTION 3.3  Selection of Securities To Be Redeemed     
                     --------------------------------------

        If less than all of the Securities are to be redeemed pursuant to
Paragraph 5 thereof, the Trustee shall select the Securities to be redeemed pro
                                                                            ---
rata or by lot or by such other method as the Trustee shall determine to be fair
- ----                                                                            
and appropriate and in such manner as complies with any applicable legal and
stock exchange requirements.

                                       24


        The Trustee shall make the selection from the Securities outstanding and
not previously called for redemption and shall promptly notify the Company in
writing of the Securities selected for redemption and, in the case of any
Security selected for partial redemption, the principal amount thereof to be
redeemed.  Securities in denominations of $1,000 may be redeemed only in whole.
The Trustee may select for redemption portions (equal to $1,000 or any integral
multiple thereof) of the principal of Securities that have denominations larger
than $1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption.

        SECTION 3.4  Notice of Redemption.
                     -------------------- 

        At least 15 days and not more than 60 days before a Redemption Date, the
Company shall mail a notice of redemption by first class mail, postage prepaid,
to the Trustee and each Holder, at such Holder's last address as then shown upon
the books of the registrar, whose Securities are to be redeemed.  At the
Company's request, the Trustee shall give the notice of redemption in the
Company's name and at the Company's expense.  Each notice for redemption shall
identify the Securities to be redeemed and shall state:

                   (1)  the Redemption Date;
        
                   (2)  the Redemption Price, including the amount of accrued
                        and unpaid interest to be paid upon such redemption;

                   (3)  the conversion price;

                   (4)  the name, address and telephone number of the Paying
                        Agent and Conversion Agent;

                   (5)  that Securities called for redemption must be
                        surrendered to the Paying Agent at the address specified
                        in such notice to collect the Redemption Price;

                   (6)  that, unless (a) the Company defaults in its obligation
                        to deposit U.S. Legal Tender with the Paying Agent in
                        accordance with Section 3.6 hereof or (b) such
                        redemption payment is prohibited pursuant to

                                       25



                        Article Twelve hereof or otherwise, interest on
                        Securities called for redemption ceases to accrue on and
                        after the Redemption Date and the only remaining right
                        of the Holders of such Securities is to receive payment
                        of the Redemption Price, including accrued and unpaid
                        interest to the Redemption Date, upon surrender to the
                        Paying Agent of the Securities called for redemption and
                        to be redeemed;

                   (7)  if any Security is being redeemed in part, the portion
                        of the principal amount, equal to $1,000 or any integral
                        multiple thereof, of such Security equal to the
                        unredeemed portion thereof and that, on and after the
                        Redemption Date, and upon surrender of such Security, a
                        new Security or Securities in aggregate principal amount
                        equal to the unredeemed portion thereof will be issued;

                   (8)  if less than all the Securities are to be redeemed, the
                        identification of the particular Securities (or portion
                        thereof) to be redeemed, as well as the aggregate
                        principal amount of such Securities to be redeemed and
                        the aggregate principal amount of Securities to be
                        outstanding after such partial redemption;

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

                   (10)  that Holders who want to convert Securities must
                         satisfy the requirements of Paragraph 8 of the
                         Securities;

                   (11)  the CUSIP number of the Securities to be redeemed; and

                   (12)  that the notice is being sent pursuant to this Section
                         3.4 and pursuant to the optional redemption provisions
                         of Paragraph 5 of the Securities.

                                       26



        SECTION 3.5  Effect of Notice of Redemption.
                     ------------------------------ 

        Once notice of redemption is mailed in accordance with Section 3.4,
Securities called for redemption become due and payable on the Redemption Date
and at the Redemption Price, including accrued and unpaid interest to the
Redemption Date.  Upon surrender to the Trustee or Paying Agent, such Securities
called for redemption shall be paid at the Redemption Price, including interest,
if any, accrued and unpaid on the Redemption Date; provided that if the
                                                   --------            
Redemption Date is after a regular Record Date and on or prior to the Interest
Payment Date, the accrued interest shall be payable to the Holder of the
redeemed Securities registered on the relevant Record Date; and provided,
                                                                -------- 
further, that if a Redemption Date is a Legal Holiday, payment shall be made on
- -------                                                                        
the next succeeding Business Day and no interest shall accrue for the period
from such Redemption Date to such succeeding Business Day.

        SECTION 3.6  Deposit of Redemption Price.
                     --------------------------- 

        On or prior to the Redemption Date, the Company shall deposit with the
Paying Agent (other than the Company or an Affiliate of the Company) U.S. Legal
Tender sufficient to pay the Redemption Price of, including accrued and unpaid
interest to the Redemption Date on, all Securities to be redeemed on such
Redemption Date (other than Securities or portions thereof called for redemption
on that date that have been delivered by the Company to the Trustee for
cancellation).  The Paying Agent shall promptly return to the Company any U.S.
Legal Tender so deposited which is not required for that purpose upon the
written request of the Company.

        If the Company complies with the preceding paragraph and the other
provisions of this Article Three and payment of the Securities called for
redemption is not prohibited under Article Twelve or otherwise, interest on the
Securities to be redeemed will cease to accrue on the applicable Redemption
Date, whether or not such Securities are presented for payment.  Notwithstanding
anything herein to the contrary, if any Security surrendered for redemption in
the manner provided in the Securities shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall continue to accrue and be paid from the Redemption
Date until such payment is made on the unpaid principal, and, to the extent

                                       27


lawful, on any interest not paid on such unpaid principal, in each case at the
rate and in the manner provided in Section 4.1 hereof and the Securities.

        SECTION 3.7  Securities Redeemed in Part.
                     --------------------------- 

        Upon surrender of a Security that is to be redeemed in part, the Company
shall execute and the Trustee shall authenticate and deliver to the Holder,
without service charge, a new Security or Securities equal in principal amount
to the unredeemed portion of the Security surrendered.

        SECTION 3.8  Conversion Arrangements on Call for Redemption.
                     ---------------------------------------------- 
  
        In connection with any redemption of Securities, the Company may (but
shall not be obligated to) arrange for the purchase and conversion of any

contrary contained in this Article Three, the obligation of the Company to pay
the Redemption Price shall be satisfied and discharged to the extent such amount
is so paid by such purchasers.  Pursuant to such an agreement, any Securities
tendered by the Holder thereof for redemption or not duly surrendered for
conversion or redemption by the Holder thereof shall be deemed acquired by such
purchasers from such Holders and surrendered by such purchasers for conversion,
all as of immediately prior to the close of business on the Business Day prior

Indenture and further stating, as to each such Officer signing such certificate,
whether or not the signer knows of any failure by the Company or any Subsidiary
of the Company to comply with any conditions or covenants in this Indenture and,
if such signor does know of such a failure to comply, the certificate shall

                                       31


describe such failure with particularity.  The Officers' Certificate shall also
notify the Trustee should the relevant fiscal year end on any date other than

        (b)  The Company shall, so long as any of the Securities are
outstanding, deliver to the Trustee, promptly upon becoming aware of any Default
or Event of Default under this Indenture, an Officers' Certificate specifying
such Default or Event of Default and what action the Company is taking or

                       ----------- 

        The Company shall deliver to the Trustee and each Holder, within 15 days
after it files the same with the SEC, copies of all reports and information (or

preceding sentence), the Company shall deliver to the Trustee and to each
Holder, within 15 days after it would have been required to file such
information with the SEC were it required to do so, financial statements,
including any notes thereto (and, in the case of a fiscal year end, an auditors'
report by an independent certified public accounting firm of established
national reputation), and a "Management's Discussion and Analysis of Financial
Condition and Results of Operations," substantially equivalent to that which it
would have been required to include in such quarterly or annual reports,
information, documents or other reports if it had been subject to the
requirements of Section 13 or 15(d) of the Exchange Act.  The Company shall also
comply with the other provisions of TIA (S) 314(a).

        (b)  Notwithstanding the foregoing, (i) with respect to any Affiliate

not Affiliates and (ii) with respect to any Affiliate Transaction or related
series of Affiliate Transactions with an aggregate value in excess of

        The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law or any usury law or
other law which would prohibit or forgive the Company from paying all or any
portion of the principal of or interest on the Securities as contemplated
herein, wherever enacted, now or at any time hereafter in force, or which may
affect the covenants or the performance of this Indenture; and (to the extent
that it may lawfully do so) the Company 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)  In the event that a Change of Control (as defined below) has
occurred, each Holder will have the right, at such Holder's option, subject to
the terms and conditions of this Section 4.10, to require the Company to
repurchase all or any part of such Holder's Notes (provided that the principal
                                                   --------

that is no later than 60 Business Days (unless later required by applicable law)
after the occurrence of such Change of Control (the "Change of Control Payment
Date"), at a cash price equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any (the "Change of Control Purchase Price"), to
the Change of Control Payment Date.

        (b)  The Company shall notify the Trustee within 10 Business Days after
the Company knows or reasonably should know as a result of a public filing of
the occurrence of each Change of Control.  Within 20 Business Days after the
Company knows or reasonably should know as a result of a public filing of the
occurrence of each Change of Control, the Company will make an unconditional
offer (a "Change of Control Offer") to all Holders of Notes to purchase all of
the Notes at the Change of Control Purchase Price by sending written notice of a
Change of Control Offer, by first class mail, to each Holder at its registered
address, with a copy to the Trustee.  The notice to Holders, which shall govern
the terms of the Offer, shall state:

             (1)  that the Change of Control Offer is being made pursuant to
     this Section 4.10 and that all Securities, or portions thereof, tendered
     will be accepted for payment;

             (3)  that any Security, or portion thereof, not tendered or
     accepted for payment will continue to accrue interest;

                                       35


             (4)  that, unless the Company defaults in depositing U.S. Legal
     Tender with the Paying Agent in accordance with the first paragraph of
     clause (c) of this Section 4.10, or payment is otherwise prevented, any
     Security, or portion thereof, accepted for payment pursuant to the Change
     of Control Offer shall cease to accrue interest after the Change of Control
     Payment Date;

             (5)  that Holders electing to have a Security, or portion thereof,
     purchased pursuant to a Change of Control Offer will be required to
     surrender the Security, with the form entitled "Option of Holder to Elect
     Purchase" on the reverse of the Security completed, to the Paying Agent
     (which may not for purposes of this Section 4.10, notwithstanding anything
     in this Indenture to the contrary, be the Company or any Affiliate of the
     Company) at the address specified in the notice prior to the close of
     business on the third Business Day prior to the Change of Control Payment
     Date (the "Final Change of Control Put Date");

             (6)  that Holders will be entitled to withdraw their election, in
     whole or in part, if the Paying Agent receives, prior to the close of
     business on the Final Change of Control Put Date, a telegram, telex,
     facsimile transmission or letter setting forth the name of the Holder, the
     principal amount of the Securities the Holder is withdrawing and a
     statement that such Holder is withdrawing his election to have such
     principal amount of Notes purchased; and

             (7)  a brief description of the events resulting in such Change of
     Control.

        (c)  On or before the Change of Control Payment Date, the Company will
(i) accept for payment Notes or portions thereof properly tendered pursuant to
the Change of Control Offer, (ii) deposit with the Paying Agent U.S. Legal
Tender sufficient to pay the Change of Control Purchase Price (together with
accrued and unpaid interest) of all Notes so tendered and (iii) deliver to the
Trustee Notes so accepted together with an Officers' Certificate identifying the
Notes or portions thereof

                                       36


being purchased by the Company.  The Paying Agent will promptly mail to the
Holders of Notes so accepted payment in an amount equal to the Change of Control
Purchase Price (together with accrued and unpaid interest), and the Trustee will
promptly authenticate and mail or deliver to such Holders a new Note equal in
principal amount to any unpurchased portion of the Note surrendered.  Any Notes
not so accepted will be promptly mailed or delivered by the Company to the
Holder thereof.  The Company will announce publicly the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.

        "Change of Control" means (i) any sale, transfer or other conveyance
(other than to the Company or a Wholly Owned Subsidiary), whether direct or
indirect, of all or substantially all of the assets of the Company, on a
consolidated basis, to any "person" or "group" in one transaction or a series of
related transactions, provided that a transaction where the holders of all
classes of Voting Stock of the Company immediately prior to such transaction
own, directly or indirectly, 50% or more of the aggregate voting power of all
classes of Voting Stock of such "person" or "group" immediately after such
transaction will not be a Change of Control, or (ii) any "person" or "group,"
other than the Management Group (as defined below) is or becomes the "beneficial
owner," directly or indirectly, of more than 50% of the total voting power of
the Voting Stock then outstanding.  The "Management Group" shall consist of at
least a majority of the executive officers of the Company as of the date of the
Indenture as disclosed in the Placement Memorandum, members of their immediate
families, certain trusts for their benefit, and legal representatives of, or
heirs, beneficiaries or legatees receiving Common Stock (or securities
convertible or exchangeable for Common Stock) under any such person's estate.

        For the purposes of this definition, (i) the terms "person" and "group"
shall have the meanings used for purposes of Rules 13d-3 and 13d-5 of the
Exchange Act, whether or not applicable; provided that no Excluded Person and no
                                         --------                               
person or group controlled by Excluded Persons shall be deemed to be a "person"
or "group" and (ii) the term "beneficial owner" shall have the meaning used in
Rules 13d-3 and 13d-5 under the Exchange Act, whether or not applicable, except
that a person shall be deemed to have "beneficial ownership" of all shares that
any such person has the right to acquire, whether such

                                       37


right is exercisable immediately or only after the passage of time or upon the
occurrence of certain events.

        Notwithstanding anything to the contrary in this Section 4.10, the
Company shall not be obligated to make any payment of the Change of Control
Purchase Price unless and until the Company shall have satisfied its
obligations, if any, to make similar payments pursuant to Section 4.l6 of the
Senior Notes Indenture.

would constitute all or substantially all of the properties and assets of the
Company on a consolidated basis, shall be deemed to be the transfer of

or into which the Company is merged or to which such transfer 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 Surviving
Person had been named as the Company herein.  When a Surviving Person duly
assumes all of the obligations of the Company pursuant hereto and pursuant to

     in the Notes or this Indenture (other than a default in the performance of
     any covenant, agreement or warranty which is specifically dealt with
     elsewhere in this Section 6.1), and continuance of such default or breach
     for a period of 45 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 Holders of at least 25% in aggregate principal amount of the
     outstanding Securities, a written notice specifying such default or breach,
     requiring it to be remedied and stating that such notice is a "Notice of
     Default" hereunder;

             (4)  a decree, judgment, or order by a court of competent
     jurisdiction shall have been entered adjudging the Company or any of its
     Material Subsidiaries as bankrupt or insolvent, or approving as properly
     filed a petition in an involuntary case or proceeding seeking
     reorganization of the Company or any of its Material Subsidiaries under any
     bankruptcy or similar law, or a decree, judgment or order of a court of
     competent jurisdiction over the appointment of a receiver, liquidator,
     trustee, or assignee in bankruptcy or insolvency of the Company, any of its
     Material Subsidiaries, or of the property of any such Person, or the
     winding up or liquidation of the affairs of any such Person, shall have
     been entered, and the continuance of any such decree, judgment or order
     unstayed and in effect for a period of 45 consecutive days;

             (5)  the Company or any of its Material Subsidiaries shall
     institute proceedings to be adjudicated a voluntary bankrupt (including
     conversion of an involuntary proceeding into a voluntary proceeding), or
     shall consent to the filing of a bankruptcy proceeding against it, or shall
     file a petition or answer or consent to the filing of any such petition, or
     shall consent to the appointment of a Custodian, receiver, liquidator,
     trustee, or assignee in bankruptcy or insolvency of it or any of its assets
     or property, or shall make a general assignment for the benefit of
     creditors, or shall admit in writing its inability

                                       40


     to pay its debts generally as they become due, or shall, within the meaning
     of any Bankruptcy Law, become insolvent, fail generally to pay its debts as
     they become due;

             (6)  (A) the acceleration of any Indebtedness (other than
     Non-Recourse Indebtedness) of the Company or any of its Subsidiaries that
     are not Unrestricted Subsidiaries that has an outstanding principal amount
     of $5,000,000 or more in the aggregate to be immediately due and payable;
     provided that, in the event any such acceleration is withdrawn or otherwise
     --------                                                                   
     rescinded (including satisfaction of such Indebtedness) within a period of
     ten business days after such acceleration by the holders of such
     Indebtedness, any Event of Default under this clause (v) will be deemed to
     be cured and any acceleration under this Indenture will be deemed withdrawn
     or rescinded; and (B) the failure by the Company or any of its Subsidiaries
     that are not Unrestricted Subsidiaries to make any principal, premium,
     interest or other required payment in respect of Indebtedness (other than

     are not Unrestricted Subsidiaries with an outstanding aggregate principal
     amount of $5,000,000 or more (after giving effect to any applicable grace
     period set forth in the documents governing such Indebtedness); and

             (7)  one or more final judgments (in the amount not covered by
     insurance or not reserved for) or the issuance of any warrant of attachment
     against any portion of the property or assets of the Company or any
     Subsidiary of the Company that is not an Unrestricted Subsidiary, which, in
     the aggregate, are at least $5,000,000 at any one time rendered against the
     Company or any of its Subsidiaries that are not Unrestricted Subsidiaries
     by a court of competent jurisdiction and not bonded, satisfied or
     discharged for a period (during which execution shall not be effectively
     stayed) of (A) 45 days after the judgment (which, if there is more than one
     judgment, causes such judgments to exceed $5,000,000 in the aggregate)
     becomes final and such court shall not have ordered or

                                       41


     approved, and the parties shall not have agreed upon, the payment of such
     judgment at a later date or dates or (B) 45 days after all or any part of
     such judgment is payable pursuant to any court order or agreement between
     the parties.

        If a Default occurs and is continuing and if it is known to the Trustee,
the Trustee must, within 90 days after the occurrence of such Default, give to
the Holders notice of such Default; provided that, except in the case of a
                                    --------                              
Default in payment of principal of, premium, if any, or interest on the Notes,
including a Default in the payment of the Change of Control Purchase Price as
required by this Indenture, the Trustee will be protected in withholding such
notice if it in good faith determines that the withholding of such notice is in
the interest of the Holders.

          SECTION 6.2  Acceleration of Maturity Date; Rescission and Annulment.
                       ------------------------------------------------------- 

        If an Event of Default occurs and is continuing (other than an Event of
Default specified in Section 6.1(4) or (5) of this Article Six, relating to the
Company or its Material Subsidiaries), then in each such case, unless the
principal of all of the Notes shall have already become due and payable, either
the Trustee or the Holders of 25% in aggregate principal amount of the Notes
then outstanding, by notice in writing to the Company (and to the Trustee if
given by the Holders) (an "Acceleration Notice"), may declare all principal,
determined as set forth below, including in each case accrued interest thereon,
or, as appropriate, the Change of Control Purchase Price (solely with respect to
a Default relating to the payment of the Change of Control Purchase Price) to be
due and payable immediately.  If an Event of Default specified in Section 6.1(4)
or (5) occurs, all principal and accrued and unpaid interest thereon will be
immediately due and payable on all outstanding Notes without any declaration or
other act on the part of the Trustee or the Holders.

        At any time after such a declaration of acceleration is made and before
a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter provided in this Article Six, the Holders of a majority
in aggregate principal amount of then outstanding Securities, by written notice
to the Company

                                       42


and the Trustee, may waive, on behalf of all Holders, any such declaration of
acceleration if:

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

          (A)    all overdue interest on all Securities,

          (B)    the principal of (and premium, if any, applicable to) any
     Securities which would become due otherwise than by such declaration of
     acceleration, and interest thereon at the rate borne by the Securities,

          (C)    to the extent that payment of such interest is lawful, interest
     upon overdue interest at the rate borne by the Securities,

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

             (2)  all Events of Default, other than the non-payment of the
     principal of, premium, if any, and interest on Securities which have become
     due solely by such declaration of acceleration, have been cured or waived
     as provided in Section 6.12, including, if applicable, any Event of Default
     relating to the covenants contained in Section 4.10.

Notwithstanding the previous sentence of this Section 6.2, no waiver shall be
effective for any Event of Default or event which with notice or lapse of time
or both would be an Event of Default with respect to any covenant or provision
which cannot be modified or amended without the consent of the Holder of each
outstanding Security, unless all such affected Holders agree, in writing, to
waive such Event of Default or event.  No such waiver shall cure or waive any
subsequent default or impair any right consequent thereon.

          SECTION 6.3  Collection of Indebtedness and Suits for Enforcement by
                       -------------------------------------------------------
Trustee.
- ------- 

        The Company covenants that if an Event of Default in payment of
principal, premium, or interest

                                       43


specified in clause (1) or (2) of Section 6.1 occurs and is continuing, the
Company shall, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal, premium (if any) and interest, and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal (and premium, if any) and on any overdue interest, at the rate borne
by the Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including compensation
to, and expenses, disbursements and advances of the Trustee, its agents and
counsel.

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

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

          SECTION 6.4  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 upon the Securities or the property
of the Company, the Trustee (irrespective of whether the principal 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 overdue principal or interest) shall be
entitled and

                                       44


empowered, by intervention in such proceeding or otherwise to take any and all
actions under the TIA, including

             (i)  to file and prove a claim for the whole amount of principal
     (and premium, if any) and interest owing and unpaid in respect of the
     Securities and to file such other papers or documents as may be necessary
     or advisable in order to have the claims of the Trustee (including any
     claim for the reasonable compensation, expenses, disbursements and advances
     of the Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding, and

             (ii)  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
other 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, to
pay to 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 7.7.

        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 6.5  Trustee May Enforce Claims Without Possession of
                       ------------------------------------------------
Securities.
- ---------- 

        All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust in favor of the Holders, and any recovery of
judgment shall, after provision for the

                                       45


payment of compensation to, and expenses, disbursements and advances of the
Trustee, its agents and counsel, be for the ratable benefit of the Holders of
the Securities in respect of which such judgment has been recovered.

          SECTION 6.6  Priorities.
                       ---------- 

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

          FIRST:  To the Trustee in payment of all amounts due pursuant to
Section 7.7;

          SECOND:  Subject to Article Twelve, to the Holders in payment of the
amounts then due and unpaid for principal of, premium (if any) and interest on,
the Securities in respect of which or for the benefit of which such money has
been collected, ratably, without preference or priority of any kind, according
to the amounts due and payable on such Securities for principal, premium (if
any) and interest, respectively; and

          THIRD:  Subject to Article Twelve, to whomever may be lawfully
entitled thereto, the remainder, if any.

          SECTION 6.7  Limitation on Suits.
                       ------------------- 

        No Holder of any Security shall have any right to order or direct the
Trustee to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

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

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

                                       46


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

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

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

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

          SECTION 6.8  Unconditional Right of Holders to Receive Principal,
                       ----------------------------------------------------
Premium and Interest.
- -------------------- 

        Notwithstanding any other provision of this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of, and premium (if any) and interest on, such Security
on the Maturity Date of such payment as expressed in such Security (in the case
of redemption, the Redemption Price on the applicable Redemption Date, and in
the case of the Change of Control Purchase Price, on the applicable Change of
Control Payment Date), and to institute suit for the enforcement of any such
payment after such respective dates, and such rights shall not be impaired
without the consent of such Holder.

          SECTION 6.9  Rights and Remedies Cumulative.
                       ------------------------------ 

        Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in Section 2.7, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other

                                       47


right or remedy, and every right and remedy shall, to the extent permitted by
law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise.  The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

          SECTION 6.10  Delay or Omission Not Waiver.
                        ---------------------------- 

        No delay or omission by the Trustee or by any Holder of any Security to
exercise any right or remedy arising upon any Event of Default shall impair the
exercise of any such right or remedy or constitute a waiver of any such Event of
Default.  Every right and remedy given by this Article Six or by law to the
Trustee or to the Holders may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee or by the Holders, as the case may be.

          SECTION 6.11  Control by Holders.
                        ------------------ 

        The Holder or Holders of a majority in aggregate principal amount of
then outstanding Securities shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred upon the Trustee, provided that:
                                                          --------      

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

             (2)  the Trustee shall not determine that the action so directed
     would be unjustly prejudicial to the Holders not taking part in such
     direction, and

             (3)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction.

          SECTION 6.12  Waiver of Past Default.
                        ---------------------- 

        Subject to Section 6.8, the Holder or Holders of not less than a
majority in aggregate principal amount of the outstanding Securities may, on
behalf of all Holders, waive any past default hereunder and its consequences,
except a default

                                       48


          (A)    in the payment of the principal of, premium, if any, or
     interest on, any Security not yet cured, or

          (B)    in respect of a covenant or provision hereof which, under
     Article Nine, cannot be modified or amended without the consent of the
     Holder of each outstanding Security affected.

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

          SECTION 6.13  Undertaking for Costs.
                        --------------------- 

        All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted to be taken by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in aggregate
principal amount of the outstanding Securities, or to any suit instituted by any
Holder for enforcement of the payment of principal of, or premium (if any) or
interest on, any Security on or after the respective Maturity Date expressed in
such Security (including, in the case of redemption, on or after the Redemption
Date).

          SECTION 6.14  Restoration of Rights and Remedies.
                        ---------------------------------- 

        If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined

                                       49


adversely to the Trustee or to such Holder, then and in every case, subject to
any determination in such proceeding, the Company, the Trustee and the Holders
shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.


                                 ARTICLE SEVEN

                                    TRUSTEE

        The Trustee hereby accepts the trust imposed upon it by this Indenture
and covenants and agrees to perform the same, as herein expressed.

          SECTION 7.1  Duties of Trustee.
                       ----------------- 

        (a)  If a Default or an Event of Default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested in it by this
Indenture and use the same degree of care and skill in their exercise as a
prudent Person would exercise or use under the circumstances in the conduct of
his own affairs.

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

             (1)  The Trustee need perform only those duties as are specifically
     set forth in this Indenture and no others, and no covenants or obligations
     shall be implied in or read into this Indenture which are adverse to the
     Trustee.

             (2)  In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture.  However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

                                       50


        (c)  The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

             (1)  This paragraph does not limit the effect of paragraph (b) of
     this Section 7.1.

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

             (3)  The Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.11.

        (d)  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 to take or omit to take any action
under this Indenture or at the request, order or direction of the Holders or in
the exercise of any of its rights or powers if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it.

        (e)  Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c), (d) and (f) of this Section 7.1.

        (f)  The Trustee shall not be liable for interest on any assets received
by it except as the Trustee may agree in writing with the Company.  Assets held
in trust by the Trustee need not be segregated from other assets except to the
extent required by law.

          SECTION 7.2  Rights of Trustee.
                       ----------------- 

          Subject to Section 7.1:

        (a)  The Trustee may rely on any document believed by it to be genuine
and to have been signed or

                                       51


presented by the proper Person.  The Trustee need not investigate any fact or
matter stated in the document.

        (b)  Before the Trustee acts or refrains from acting, it may consult
with counsel and may require an Officers' Certificate or an Opinion of Counsel,
which shall conform to Sections 13.4 and 13.5.  The Trustee shall not be liable
for any action it takes or omits to take in good faith in reliance on such
certificate or opinion.

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

        (d)  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.

        (e)  The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, notice, request, direction, consent, order, bond, debenture, or other
paper or document, but the Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit.

        (f)  The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders, pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.

          SECTION 7.3  Individual Rights of Trustee.
                       ---------------------------- 

        The Trustee in its individual or any other capacity may become the owner
or pledgee of Securities and may otherwise deal with the Company, its
Subsidiaries, or their respective Affiliates with the same rights it would have
if it were not Trustee.  Any Agent may do the same with like rights.  However,
the Trustee must comply with Sections 7.10 and 7.11.

                                       52


          SECTION 7.4  Trustee's Disclaimer.
                       -------------------- 

        The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Securities and it shall not be accountable for the
Company's use of the proceeds from the Securities, and it shall not be
responsible for any statement in the Securities, other than the Trustee's
certificate of authentication, or the use or application of any funds received
by a Paying Agent other than the Trustee.

          SECTION 7.5  Notice of Default.
                       ----------------- 

        If a Default occurs and is continuing and if it is known to the Trustee,
the Trustee must, within 90 days after the occurrence of such default, mail to
each Holder notice of such Default, except in the case of a default in payment
of principal of, premium, if any, or interest on, the Notes, including a default
in the payment of the Change of Control Purchase Price as required by this
Indenture.  The Trustee will be protected in withholding such notice if it in
good faith determines that the withholding of such notice is in the interest of
the Holders.

          SECTION 7.6  Reports by Trustee to Holders.
                       ----------------------------- 

        Within 60 days after each May 15, beginning with the May 15 following
the date of this Indenture, the Trustee shall, if required, mail to each Holder
a brief report dated as of such May 15 that complies with TIA (S)313(a).  The
Trustee also shall comply with TIA (S)(S) 313(b) and 313(c).

        The Company shall promptly notify the Trustee in writing if the
Securities become listed on any stock exchange or automatic quotation system.

        A copy of each report at the time of its mailing to Holders shall be
mailed to the Company and filed with the SEC and each stock exchange, if any, on
which the Securities are listed.

          SECTION 7.7  Compensation and Indemnity.
                       -------------------------- 

        The Company shall pay to the Trustee from time to time reasonable
compensation for its services.  The Trustee's compensation shall not be limited
by any law on compensation of a trustee of an express trust.  The Company shall
reimburse the Trustee upon request for all

                                       53


reasonable disbursements, expenses and advances incurred or made by it.  Such
expenses shall include the reasonable compensation, disbursements and expenses
of the Trustee's agents, accountants, experts and counsel.

        The Company shall indemnify the Trustee (in its capacity as Trustee) and
each of its officers, directors, attorneys-in-fact and agents for, and hold it
harmless against, any claim, demand, expense (including but not limited to
reasonable compensation, disbursements and expenses of the Trustee's agents and
counsel), loss or liability incurred by it without negligence or bad faith on
its part, arising out of or in connection with the administration of this trust
and its rights or duties hereunder 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 notify the Company promptly of any claim asserted against the Trustee for
which it may seek indemnity.  The Company shall defend the claim and the Trustee
shall provide reasonable cooperation at the Company's expense in the defense. 
The Trustee may have separate counsel and the Company shall pay the reasonable
fees and expenses of such counsel; provided that the Company will not be
                                   --------                             
required to pay such fees and expenses if it assumes the Trustee's defense and
there is no conflict of interest between the Company and the Trustee in
connection with such defense. The Company need not pay for any settlement made
without its written consent.  The Company need not reimburse any expense or
indemnify against any loss or liability to the extent incurred by the Trustee
through its negligence, bad faith or willful misconduct.

        To secure the Company's payment obligations in this Section 7.7, the
Trustee shall have a lien prior to the Securities on all assets held or
collected by the Trustee, in its capacity as Trustee, except assets held in
trust to pay principal and premium, if any, of or interest on particular
Securities.

        When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

        The Company's obligations under this Section 7.7 and any lien arising
hereunder shall survive the

                                       54


resignation or removal of the Trustee, the discharge of the Company's
obligations pursuant to Article Eight of this Indenture and any rejection or
termination of this Indenture under any Bankruptcy Law.

          SECTION 7.8  Replacement of Trustee.
                       ---------------------- 

        The Trustee may resign by so notifying the Company in writing.  The
Holder or Holders of a majority in principal amount of the outstanding
Securities may remove the Trustee by so notifying the Company and the Trustee in
writing and may appoint a successor trustee with the Company's consent.  The
Company may remove the Trustee if:

             (1)  the Trustee fails to comply with Section 7.10;

             (2)  the Trustee is adjudged bankrupt or insolvent;

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

             (4)  the Trustee 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 a successor
Trustee. Within one year after the successor Trustee takes office, the Holder or
Holders of a majority in principal amount of the Securities may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

        A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Immediately after that
and provided that all sums owing to the Trustee provided for in Section 7.7 have
been paid, the retiring Trustee shall transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided in Section 7.7,
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.  A successor Trustee shall mail notice of its
succession to each Holder.

                                       55


        If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holder or Holders of at least 10% in principal amount of the outstanding
Securities may petition any court of competent jurisdiction for the appointment
of a successor Trustee.

        If the Trustee fails to comply with Section 7.10, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

        Notwithstanding replacement of the Trustee pursuant to this Section 7.8,
the Company's obligations under Section 7.7 shall continue for the benefit of
the retiring Trustee.

          SECTION 7.9  Successor Trustee by Merger, Etc.
                       ---------------------------------

        If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee.

          SECTION 7.10  Eligibility; Disqualification.
                        ----------------------------- 

        The Trustee shall at all times satisfy the requirements of TIA (S)
310(a)(1) and TIA (S) 310(a)(5).  The Trustee shall have a combined capital and
surplus of at least $50,000,000 as set forth in its most recent published annual
report of condition.  The Trustee shall comply with TIA (S) 310(b).

          SECTION 7.11  Preferential Collection of Claims Against Company.
                        ------------------------------------------------- 

        The Trustee shall comply with TIA (S) 311(a), excluding any creditor
relationship listed in TIA (S)311(b).  A Trustee who has resigned or been
removed shall be subject to TIA (S) 311(a) to the extent indicated.

                                       56

          SECTION 8.1  Satisfaction, Discharge of the Indenture, Covenant
                       --------------------------------------------------
Defeasance.
- ---------- 

        The Company shall be deemed to have paid and discharged the entire
Indebtedness on the Notes and this Indenture shall cease to be of further effect
(except as to (i) rights of registration of transfer, substitution and exchange
of Notes and the Company's right of optional redemption, (ii) rights of Holders
to receive payments of principal of, premium, if any, and interest on the Notes
(but not the Change of Control Purchase Price of the Notes) and any other rights
of the Holders with respect to such amounts, (iii) the rights, obligations and
immunities of the Trustee under the Indenture and (iv) certain other specified
provisions in this Indenture (the foregoing exceptions (i) through (iv) are
collectively referred to as the "Reserved Rights")), if:

             (1)  the Company irrevocably deposits in trust for the benefit of
     the Holders of the Notes with the Trustee, pursuant to an irrevocable trust
     and security agreement in form and substance reasonably satisfactory to the
     Trustee, (i) U.S. Legal Tender in an amount, (ii) U.S. Government
     Obligations, or (iii) a combination thereof after payment of all Federal,
     state and local taxes or other charges or assessments in respect thereof
     payable by the Trustee, which through the payment of principal and interest
     will provide, not later than one day before the due date of payment in
     respect of the Notes, U.S. Legal Tender in an amount which, in the opinion
     of a nationally recognized firm of independent certified public accountants
     expressed in a written certification thereof (in form and substance
     reasonably satisfactory to the Trustee) delivered to the Trustee, is
     sufficient to pay the principal of, premium, if any, and interest on the
     Notes then outstanding on the dates on which any such payments are due and
     payable in accordance with the terms of this Indenture and of the Notes;

                                       57


             (2)  such deposits shall not cause the Trustee to have a
     conflicting interest as defined in and for purposes of the TIA;

             (3)  no Default or Event of Default shall have occurred or be
     continuing on the date of such deposit or shall occur on or before the 91st
     day (or one day after such greater period of time in which any such deposit
     of trust funds may remain subject to bankruptcy or insolvency laws) after
     the date of such deposit, and such deposit will not result in a Default or
     Event of Default under this Indenture or a breach or violation of, or
     constitute a default under, any other instrument to which the Company or
     any Subsidiary of the Company other than an Unrestricted Subsidiary is a
     party or by which it or its property is bound;

             (4)  the deposit, defeasance and discharge will not be deemed, or
     result in, a Federal income taxable event to the Holders of the Securities
     and the Holders will be subject to Federal income tax in the same amounts
     and in the same manner and at the same times as would have been the case if
     such deposit and defeasance had not occurred;

             (5)  the deposit shall not result in the Company, the Trustee or
     the trust being subject to regulation under the Investment Company Act of
     1940;

             (6)  after the passage of 90 days (or any greater period of time in
     which any such deposit of trust funds may remain subject to Bankruptcy Laws
     insofar as those laws apply to the Company) following the irrevocable
     deposit of the trust funds, such funds will not be subject to any
     Bankruptcy Laws affecting creditors' rights generally;

             (7)  Holders of the Securities will have a valid, perfected and
     unavoidable (under applicable bankruptcy or insolvency laws), subject to
     the passage of time referred

     to in clause (6) above, first-priority security interest in the trust
     funds; and

             (8)  the Company has delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel (who may be outside counsel to the
     Company, but not in-house counsel to the Company) (other than an Opinion of
     Counsel with respect to clause (7)), each in form and substance
     satisfactory to the Trustee, stating that it has complied with all
     conditions precedent specified in this Indenture.

        In the event all or any portion of the Securities are to be redeemed
through such irrevocable trust, the Company must make arrangements satisfactory
to the Trustee, for the giving of the notice of such redemption or redemptions
by the Trustee in the name and at the expense of the Company.

        In the event that the Company takes the necessary action to comply with
the provisions described in this Section 8.1 and the Securities are declared due
and payable because of the occurrence of an Event of Default within the time
period specified in Section 8.1(3), or at any time under Section 8.3, the
Company will remain liable for all amounts due on the Securities at the time of
acceleration resulting from such Event of Default in excess of the amount of
U.S. Legal Tender and U.S. Government Obligations deposited with the Trustee
pursuant to this Section 8.1 at the time of such acceleration.

          SECTION 8.2  Termination of Obligations Upon Cancellation of the
                       ---------------------------------------------------

     delivered to the Trustee for cancellation or (B) all such Notes not
     theretofore delivered to the Trustee for cancellation have become due and
     payable or will become due and payable within one year and the Company has
     irrevocably

                                       59


     deposited or caused to be deposited with the Trustee for the benefit of the
     Holders of the Notes U.S. Legal Tender or U.S. Governmental Obligations in
     an amount sufficient to pay and discharge the entire indebtedness on the
     Notes, not theretofore delivered to the Trustee for cancellation, for
     principal of, premium, if any, and interest on the Notes, to the date of
     deposit or Stated Maturity or redemption and with respect to this clause
     (B) no default or Event of Default shall have occurred or be continuing on
     the date of such deposit or shall occur on or before the 91st day (or one
     day after such greater period of time in which any such deposit of trust
     funds may remain subject to bankruptcy or insolvency laws) after the date
     of such deposit, and such deposit will not result in a Default or Event of
     Default under this Indenture or a breach or violation of, or constitute a
     default under, any other instrument to which the Company or any Subsidiary
     of the Company is a party or by which it or its property is bound;

     Trustee upon request shall acknowledge in writing the discharge of the
     Company's obligations under this Indenture except for those surviving
     obligations specified in Section 8.3.

             The Trustee shall hold any U.S. Legal Tender or U.S. Government

             Subject to Section 6.8, with the consent of the Holders of not less
     than a majority in aggregate principal amount of then outstanding Notes, by
     written act of said Holders delivered to the Company and the Trustee, the
     Company, when authorized by Board Resolutions, and the Trustee may amend or
     supplement this Indenture or the Notes or enter into an indenture or
     indentures supplemental hereto for the purpose of adding any provisions to
     or changing in any manner or eliminating any of the provi-

                                       63


     sions of this Indenture or the Notes or of modifying in any manner the
     rights of the Holders under this Indenture or the Securities.  Subject to
     Section 6.8, the Holder or Holders of not less than a majority in principal
     amount of then outstanding Securities may waive compliance by the Company
     with any provision of this Indenture or the Securities.  Notwithstanding
     any of the above, however, no such amendment, supplemental indenture or
     waiver shall, without the consent of the Holder of each outstanding Note
     affected thereby:

             (1)  reduce the percentage of principal amount of Securities whose
     Holders must consent to an amendment, supplement or waiver of any provision
     of this Indenture or the Securities;

             (2)  reduce the rate or extend the time for payment of interest on
     any Security;

             (3)  reduce the principal amount of any Security, reduce the Change
     of Control Purchase Price, or the Redemption Price;

             (4)  change the Maturity Date of any Security;

             (5)  alter the redemption provisions of Article Three or the terms
     or provisions of Section 4.10, in any case, in a manner adverse to any
     Holder;

             (6)  make any changes in the provisions concerning waivers of
     Defaults or Events of Default by Holders of the Securities (except to
     increase any required percentage or to provide that certain other
     provisions hereof cannot be modified or waived without the consent of the
     Holders of each outstanding Security affected thereby) or the rights of
     Holders to recover the principal or premium of, interest on, or redemption
     payment with respect to, any Security;

             (7)  make any changes in Section 6.4, 6.7 or the third sentence of
     this Section 9.2;

                                       64


             (8)  make the principal of, or the interest on, any Security
     payable with anything or in any manner other than as provided for in this
     Indenture (including changing the place of payment where, or the coin or
     currency in which, any Security or any premium or the interest thereon is
     payable) and the Securities as in effect on the date hereof; or

             (9)  make the Securities expressly subordinated in right of payment
     to any extent not contemplated by Article Twelve or under any circumstances
     not contemplated by Article Twelve to any other Indebtedness.

        It shall not be necessary for the consent of the Holders under this
Section 9.2 to approve the particular form of any proposed amendment, supplement
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

        After an amendment, supplement or waiver under this Section 9.2 becomes
effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment, supplement or waiver.  Any failure of the
Company to mail such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such supplemental indenture.

        After an amendment, supplement or waiver under this Section 9.2 or 9.4
becomes effective, it shall bind each Holder.

        In connection with any amendment, supplement or waiver under this
Article Nine, the Company may, but shall not be obligated to, offer to any
Holder who consents to such amendment, supplement or waiver, or to all Holders,
consideration for such Holder's consent to such amendment, supplement or waiver.

          SECTION 9.3  Compliance with TIA.
                       ------------------- 

        Every amendment, waiver or supplement of this Indenture or the
Securities shall comply with the TIA as then in effect.

                                       65


          SECTION 9.4  Revocation and Effect of Consents.
                       --------------------------------- 

        Until an amendment, waiver or supplement becomes effective, a consent to
it by a Holder is a continuing consent by the Holder and every subsequent Holder
of a Note or portion of a Note that evidences the same debt as the consenting
Holder's Note, even if notation of the consent is not made on any Note. 
However, any such Holder or subsequent Holder may revoke the consent as to his
Note or portion of his Note by written notice to the Company or the Person
designated by the Company as the Person to whom consents should be sent if such
revocation is received by the Company or such Person before the date on which
the Trustee receives an Officers' Certificate certifying that the Holders of the
requisite principal amount of Notes have consented (and not theretofore revoked
such consent) to the amendment, supplement or waiver.

        The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver, which record date shall be the date so fixed by the
Company notwithstanding the provisions of the TIA. If a record date is fixed,
then notwithstanding the last sentence of the immediately preceding paragraph,
those Persons who were Holders at such record date, and only those Persons (or
their duly designated proxies), shall be entitled to revoke any consent
previously given, whether or not such Persons continue to be Holders after such
record date.  No such consent shall be valid or effective for more than 90 days
after such record date.

        After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (1)
through (9) of Section 9.2, in which case, the amendment, supplement or waiver
shall bind only each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security; provided that any such waiver shall
                                          --------                           
not impair or affect the right of any Holder to receive payment of principal and
premium of and interest on a Security, on or after the respective dates set for
such amounts to become due and payable expressed in such Security, or to bring
suit for the enforcement of any such payment on or after such respective dates.

                                       66


          SECTION 9.5  Notation on or Exchange of Securities.
                       ------------------------------------- 

        If an amendment, supplement or waiver changes the terms of a Note, the
Trustee may require the Holder of the Note to deliver it to the Trustee or
require the Holder to put an appropriate notation on the Note.  The Trustee may
place an appropriate notation on the Note about the changed terms and return it
to the Holder. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for the Note shall issue and the Trustee shall authenticate
a new Note that reflects the changed terms.  Any failure to make the appropriate
notation or to issue a new Note shall not affect the validity of such amendment,
supplement or waiver.

          SECTION 9.6  Trustee to Sign Amendments, Etc.
                       --------------------------------

        The Trustee shall execute any amendment, supplement or waiver authorized
pursuant to this Article Nine; provided that the Trustee may, but shall not be
                               --------                                       
obligated to, execute any such amendment, supplement or waiver which affects the
Trustee's own rights, duties or immunities under this Indenture.  The Trustee
shall be entitled to receive, and shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of any amendment, supplement or
waiver authorized pursuant to this Article Nine is authorized or permitted by
this Indenture.

outstanding, and if the Company and the Trustee are either present by duly
authorized representatives or have, before or after the meeting, waived notice.

          SECTION 10.3  Call of Meetings by Company or Holders.
                        --------------------------------------

                                       68

appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, and submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think appropriate.  Such regulations may fix
a record date and time for determining the Holders of record of Notes entitled

Holders of Notes at the record date and time so fixed, or their proxies, shall
be entitled to vote at such meeting whether or not they shall be such Holders at

                                       69


        The Trustee shall, by an instrument in writing, appoint a temporary

          SECTION 10.7  Exercise of Rights of Trustee or Holders May Not Be
                        ---------------------------------------------------
Hindered or Delayed by Call of Meeting.
- -------------------------------------- 

        Nothing contained in this Article Ten shall be deemed or construed to
authorize or permit, by reason of any call of a meeting of Holders or any rights
expressly or impliedly conferred hereunder to make such call, any hindrance or
delay in the exercise of any right or rights conferred upon or reserved to the
Trustee or to the Holders under any of the provisions of this Indenture or of

                                 ARTICLE ELEVEN

                                   CONVERSION

          SECTION 11.1  Conversion Privilege.
                        -------------------- 

        A Holder of a Security may convert it, or a portion thereof, subject to
prior redemption or repurchase, into Common Stock at any time during the period
stated in Paragraph 8 of the Securities.

        The initial conversion rate is stated in Paragraph 8 of the Securities. 
The conversion rate is subject to adjustment in accordance with Sections 11.6
through 11.14.

        The right to convert Notes called for redemption or subject to an offer
to repurchase will terminate at the close of business on the second Business Day
prior to the redemption or repurchase date, and will be lost if not exercised
prior to that time unless the Company defaults in making the payments due upon
redemption or repurchase.

                                       71


        A Holder may convert a portion of a Security if the portion is $1,000 or
integral multiples thereof. Provisions of this Indenture that apply to
conversion of all of a Security also apply to conversion of a portion of it.

          SECTION 11.2  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").  As soon as
practicable, the Company shall deliver to the Holder through the Conversion
Agent a certificate for the number of full shares of Common Stock issuable upon
conversion and a check in lieu of any fractional share.  The person in whose
name the certificate is registered shall be treated as a stockholder of record
on and after the Conversion Date.

        If any Note is converted between the record date for the payment of
interest and the next succeeding Interest Payment Date, such Note must be
accompanied by funds equal to the interest payable on such succeeding Interest
Payment Date on the principal amount so converted (unless such Note shall have
been called for redemption, in which case no such payment shall be required). A
Note converted on an Interest Payment Date need not be accompanied by any
payment, and the interest on the principal amount of the Note being converted
will be paid on such Interest Payment Date to the registered holder of such Note
on the immediately preceding record date. Subject to the aforesaid right of the
registered holder to receive interest, no payment or adjustment will be made on
conversion for interest accrued on the converted Note or for dividends on the
Common Stock issued on conversion.

        If a Holder converts more than one Security at the same time, the number
of full shares issuable upon the conversion shall be based on the total
principal amount of the Securities converted.

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

                                       72


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

          SECTION 11.3  Fractional Shares.
                        ----------------- 

        The Company will not issue a fractional share of Common Stock upon
conversion of a Security.  Instead the Company will deliver its check for the
market value of a fractional share.  The market value of a fraction of a share
shall be determined by multiplying the market price of a full share of Common
Stock by such fraction and rounding the result to the nearest cent.

        The market price of a share of Common Stock for the purposes of this
Section 11.3 shall be the last reported sale price of a share of Common Stock on
the principal national securities exchange on which the shares of Common Stock
are listed or admitted to trading or on the National Association of Securities
Dealers National Market System ("NMS") on the first Business Day prior to the
day of conversion, or, if the Common Stock is not then listed on an exchange,
the closing sale price (or the quoted closing bid price if there were no sales)
as reported by the National Association of Securities Dealers Automated
Quotation System ("NASDAQ") on the first business day prior to the day of
conversion.  In the absence of one or more such quotations, the Board of
Directors shall determine in good faith the current market price.

          SECTION 11.4  Taxes on Conversion.
                        ------------------- 

        The Company shall pay any documentary, stamp or similar issue or
transfer tax due on the issue of shares of Common Stock upon the conversion. 
However, the Holder shall pay any such tax which is due because the shares are
issued in a name other than that of the Holder.

          SECTION 11.5  Company to Provide Stock.
                        ------------------------ 

        The Company shall reserve out of its authorized but unissued Common
Stock or its Common Stock held in treasury shares of Common Stock sufficient to
permit the conversion of all of the Securities at any time.

                                       73


        All shares of Common Stock which may be issued upon conversion of the
Securities shall be validly issued, fully paid and non-assessable.

        The Company will endeavor to comply with all securities laws regulating
the offer and delivery of shares of Common Stock upon conversion of Securities
and will cause such shares to be listed on each national securities exchange on
which the Common Stock is then listed.

          SECTION 11.6  Conversion Price Adjustment.
                        --------------------------- 

          If 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; or

             (4)  issues by reclassification of its Common Stock any shares of
     its capital stock (including any such reclassification in connection with a
     consolidation or merger in which the Company is the continuing
     corporation),

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 of capital stock of the
Company which he would have owned immediately following such action if he 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.

                                       74


        After such allocation, the conversion privilege and the conversion rate
of each class of capital stock shall thereafter be subject to adjustment on
terms comparable to those applicable to Common Stock in this Article Eleven.

          SECTION 11.7  Adjustment for Shares Issued Below Market Price.
                        ----------------------------------------------- 

        If the Company shall pay a dividend, make a distribution or otherwise
issue rights, options, or warrants to holders of Common Stock, as such,
entitling them to subscribe for or purchase shares of Common Stock (or
securities convertible or exchangeable into Common Stock) at a price per share
of Common Stock (or having an initial conversion or exchange price per share of
Common Stock, if a security convertible or exchangeable into Common Stock) less
than the Current Market Price of a share of Common Stock on the record date
relating to such dividend, distribution or issuance, then, immediately after
such record date, the conversion rate shall be adjusted in accordance with the
following formula:
 
                                        N x P
                                        -----
                                  O +     M
                                  ---------
                        C' = C x  O +   N
 
where:
 
                   
  C'                =    the adjusted conversion rate.
 
  C                 =    the then current conversion rate.
 
  O                 =    the number of shares of Common
                         Stock outstanding on the record
                         date.
 
  N                 =    the number of additional shares of
                         Common Stock offered or issuable
                         on the exercise of the rights,

and shall become effective immediately after such record date.  If such rights
or warrants are not issued, the conversion rate shall be immediately readjusted,
effective as of the date when the Board of Directors determines not to issue
such rights or warrants, to the conversion rate which would then be in effect if
such record date had not been fixed.  If such rights or warrants are issued but,
at the end of the period during which such warrants or rights are exercisable,
not all warrants or rights shall have been exercised, the conversion rate shall
be immediately readjusted to what it would have been if "N" in the above formula
had been the number of shares actually issued.

          SECTION 11.8  Adjustment for Other Distributions.
                        ---------------------------------- 

        If the Company shall set a record date to pay a dividend or make a
distribution to holders of shares of Common Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of (i) securities other than Common
Stock, (ii) evidences of its indebtedness, (iii) assets, or (iv) rights,
options, or warrants to acquire securities of the Company, then in each such
case the conversion rate in effect immediately after the applicable record date
shall be adjusted in accordance with the following formula:
 
                        C' = C x M - F
                                 -----
                                   M
 
where:
 
                 
  C'                = the adjusted conversion rate.
 
  C                 = the then current conversion rate.
 
  M                 = the Current Market Price per share
                      of Common Stock on the applicable
                      record date.
 
  F                 = the aggregate fair market value (as
                      reasonably determined in good faith
                      by the Board of Directors of the
                      Company) on the applicable record
                      date of the assets (including cash),
                      indebtedness, securities, rights or
                      warrants divided by the number of
                      outstanding shares of Common Stock.


                                       76


        The adjustment shall be made successively whenever any such distribution
is made and shall become effective immediately after such record date.  In the
event that such distribution is not made, the conversion rate then in effect
shall be readjusted, effective as of the date when the Board of Directors
determines not to make such distribution, to the conversion rate which would
then be in effect if such record date had not been fixed.  Such adjustment shall
be made successively whenever such a record date is fixed.

        If at the end of the period during which any warrants or rights
described by subsection 11.8(iv) are exercisable, not all of such warrants,
options, or rights shall have been exercised, the conversion rate shall be
immediately readjusted to what it would have been if "F" in the above formula
had not included the fair market value on the record date of such expired
warrants or rights, but were still divided by the same number of outstanding
shares of Common Stock.

        This Section 11.8 shall not apply to cash dividends paid out of the
Company's consolidated cumulative earnings after the Issue Date.  In addition,
this Section 11.8 does not apply to distributions referred to in Section 11.6 or
rights, options or warrants referred to in Section 11.7.

        This Section does not apply to cash dividends or cash distributions paid
out of consolidated current or retained earnings as shown on the books of the
Company.

        Notwithstanding the foregoing, in the event that the Company shall
distribute rights or warrants (other than those referred to in Section 11.7
above) ("Rights") pro rata to holders of Common Stock, the Company may, in lieu
                  --- ----                                                     
of making any adjustment pursuant to this Section 11.8, make proper provision so
that each Holder of a Security who converts such Security (or any portion
thereof) after the record date for such distribution and prior to the expiration
or redemption of the Rights shall be entitled to receive upon such conversion,
in addition to the shares of Common Stock issuable upon such conversion, a
number of Rights to be determined as follows: (i) if such conversion occurs on
or prior to the date for the distribution to the holders of Rights of separate
certificates evidencing such Rights (the "Distribution Date"), the same number
of Rights to which a holder of a number of shares of Common Stock equal to the

                                      77


number of shares of Common Stock issuable upon such conversion is entitled at
the time of such conversion in accordance with the terms and provisions of and
applicable to the Rights; and (ii) if such conversion occurs after the
Distribution Date, the same number of Rights to which a holder of the number of
shares of Common Stock into which the principal amount of the Security so
converted was convertible immediately prior to the Distribution Date would have
been entitled on the Distribution Date in accordance with the terms and
provisions of and applicable to the Rights.

        SECTION 11.9  Adjustment for Common Stock Issuances.
                      ------------------------------------- 

        If the Company issues shares of Common Stock for a consideration per
share less than the Current Market Price per share of Common Stock on the date
the Company fixes the offering price of such additional shares, the conversion
rate shall be adjusted in accordance with the following formula:
 
                                          P
                                         ---

                          C' = C   x    A
 
where:
 
                   
 
     C'       =         the adjusted conversion rate.
 
     C        =         the then current conversion rate.
 
     O        =         the number of shares outstanding
                        immediately prior to the issuance of
                        such additional shares.
 
     P        =         the aggregate consideration received
                        for the issuance of such additional
                        shares.
 
     M        =         the Current Market Price per share on
                        the date of issuance of such additional
                        shares.
 
     A        =         the number of shares outstanding
                        immediately after the issuance of such
                        additional shares.
 

                                      78


        The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance.

        This Section 11.9 does not apply to (i) any of the transactions
described in Sections 11.7, 11.8 or 11.10, (ii) Common Stock issued to the
Company's employees under bona fide employee benefit plans, or issued by the
                          ---- ----                                         
Company pursuant to an employment agreement or consulting agreement, which plan
or agreement has been adopted or approved by the Board of Directors of the
Company and, when required by law, approved by the holders of Common Stock, if
such Common Stock would otherwise be covered by this Section 11.9 (but only to
the extent that the aggregate number of shares excluded hereby and issued after
the Issue Date pursuant to such plans and agreements shall not exceed 15% of the
Common Stock outstanding at the time of the adoption of any such plan or
agreement, exclusive of antidilution adjustments thereunder), (iii) Common Stock
issued to shareholders of any Person which, in an arm's-length transaction,
merges into or with the Company, or any Subsidiary of the Company, in proportion
to their stock holdings of such Person immediately prior to such merger, upon

Directors of the Company and described in a Board Resolution which the Company
shall cause to be given to the Conversion Agent, shall exceed 15%), (vi) the
Company's Common Stock issued upon the exercise of warrants, rights or options

        SECTION 11.10  Adjustment for Issuances of Convertible Securities.
                       -------------------------------------------------- 

        If the Company issues any securities convertible into or exchangeable or
exercisable for Common Stock (other than securities issued in transactions
described in Sections 11.7, 11.8, or 11.9) for a consideration per share of
Common Stock initially deliverable upon conversion, exchange or exercise of such
securities less than the Current Market Price per share on the date of issuance
of such securities, or if such securities are not immediately convertible,
exchangeable or exercisable, on the date such securities become convertible,
exchangeable or exercisable the conversion rate shall be adjusted in accordance
with the following formula:

 
                                          P

                            C' = C x  O + D
 
where:
 
                  
      C'      =        the adjusted conversion rate.
 
      C       =        the then current conversion rate.

      M       =        the Current Market Price per share
                       on the date of issuance of such

                       securities become convertible,
                       exchangeable or exercisable.
 
      D       =        the maximum number of shares

                       securities at the initial
                       conversion, exchange or exercise
                       rate.
 

        The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance.

        If all of the Common Stock deliverable upon conversion, exchange or
exercise of such securities has

                                      80


not been issued when such securities are no longer outstanding, then the
conversion rate shall promptly be readjusted to the conversion rate which would
then be in effect had the adjustment upon the issuance of such securities been
made on the basis of the actual number of shares of Common Stock issued upon
conversion, exchange or exercise of such securities.

        This Section 11.10 does not apply to (i) securities convertible into or
exchangeable or exercisable for Common Stock issued to shareholders of any
person which, in an arm's-length transaction, merges into or with the Company,

        SECTION 11.11  Adjustment to Number of Conversion Shares.
                       ----------------------------------------- 

        Upon each adjustment of the conversion rate pursuant to this Article
Eleven, each Note shall thereupon evidence the right to purchase that number of
shares of Common Stock (calculated to the nearest hundredth of a share) obtained
by multiplying the number of shares of Common Stock purchasable upon conversion
of the Note immediately prior to such adjustment by the conversion rate in
effect immediately prior to such adjustment and dividing the product so obtained
by the conversion rate in effect immediately after such adjustment.  The
adjustment pursuant to this Section 11.11 to the number of shares of Common
Stock purchasable upon conversion of a Note shall be made each time an
adjustment of the conversion rate is made pursuant to this Article Eleven.

        SECTION 11.12  Voluntary Adjustment.
                       -------------------- 

        The Company at any time may lower the conversion rate, temporarily or
otherwise, so long as such action does not cause Common Stock to be issued at
less than its par value.

        SECTION 11.13  Current Market Price.
                       -------------------- 

        In this Article Eleven the "Current Market Price" per share of Common
Stock on any date is the average of the last reported sale prices of a share of
Common Stock on the principal national securities exchange on which the shares
of Common Stock are listed or admitted to trading or, if not traded thereon, on
the NMS, or, if the Common Stock is not then listed on such an exchange or on
the NMS, the closing sale prices (or the quoted closing bid prices if there were
no sales) as reported by NASDAQ for any 20 consecutive trading days commencing
30 trading days before the date in question.  In the absence of one or more such
quotations, the Board of Directors reasonably and in good faith shall determine
the Current Market Price.

        SECTION 11.14  Consideration Received.
                       ---------------------- 

        For purposes of any computation respecting consideration received
pursuant to Sections 11.9 and 11.10, the following shall apply:

                                      82


             (1)  in the case of the issuance of shares of Common Stock for
     cash, the consideration shall be the amount of such cash, provided that in
                                                               --------        
     no case shall any deduction be made for any commissions, discounts or other
     expenses incurred by the Company for any underwriting of the issue or
     otherwise in connection therewith;

             (2)  in the case of the issuance of shares of Common Stock for a
     consideration in whole or in part other than cash, the consideration other
     than cash shall be deemed to be the fair market value thereof as determined
     in good faith by the Board of Directors (irrespective of the accounting
     treatment thereof) and described in a Board Resolution which shall be filed
     with the Trustee; and

             (3)  in the case of the issuance of securities convertible into or
     exchangeable for shares, the aggregate consideration received therefor
     shall be deemed to be the consideration received by the Company for the
     issuance of such securities plus the additional minimum consideration, if
     any, to be received by the Company upon the conversion or exchange thereof
     (the consideration in each case to be determined in the same manner as
     provided in clauses (1) and (2) of this Section).

        SECTION 11.15  When Adjustment May Be Deferred.
                       ------------------------------- 

        No adjustment in the conversion rate need be made unless the adjustment
would require a change of at least l% in the conversion rate then in effect;
provided, however, that any adjustments that would otherwise be required to be
- --------  -------
made shall be carried forward and taken into account in any subsequent
adjustment.

        All calculations under this Article Eleven shall be made to the nearest
cent or to the nearest 1/100th of a share, as the case may be.

        In any case in which this Article Eleven shall require that an
adjustment shall become effective immediately after a record date for an event,
the Company may defer until the occurrence of such event (1) issuing to

                                      83


the Holder of any Security converted after such record date and before the
occurrence of such event the additional shares of Common Stock issuable upon
such conversion by reason of the adjustment required by such event over and
above the shares of Common Stock issuable upon such conversion before giving
effect to such adjustment and (2) paying to such Holder any amount in cash in
lieu of a fractional share of Common Stock pursuant to Section 11.3; provided,
                                                                     --------
however, that the Company shall deliver to such Holder a due bill or other
- -------
appropriate instrument evidencing such Holder's rights to receive such
additional shares of Common Stock, and such cash, upon the occurrence of the
event requiring such adjustment.

        SECTION 11.16  When No Adjustment Required.
                       --------------------------- 

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

        SECTION 11.17  Notice of Adjustment.
                       -------------------- 

        Whenever the conversion rate is adjusted, the Company shall promptly
mail to Holders a notice of the adjustment.  The Company shall file with the
Trustee an Officers' Certificate or a certificate from the Company's independent
public accountants briefly stating the facts requiring the adjustment and the
manner of computing it. The certificate shall be conclusive evidence that the
adjustment is correct, absent manifest error.

        SECTION 11.18  Notice of Certain Transactions.
                       ------------------------------ 
        If:

             (1)  the Company proposes to take any action that would require an
     adjustment in the conversion rate,

             (2)  the Company proposes to take any action that would require a
     supplemental indenture pursuant to Section 11.19, or

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

the Company shall mail to Holders a notice stating the proposed record date for
a dividend or distribution or the proposed effective date of a subdivision,
combination, reclassification, consolidation, merger, transfer,

                                      84


lease, liquidation or dissolution.  The Company shall mail the notice at least
15 days before such date. Failure to mail the notice or any defect therein shall
not affect the validity of the transaction.

        SECTION 11.19  Reorganization of the Company.
                       ----------------------------- 

        If the Company is a party to a transaction subject to Section 5.1 or a
merger which reclassifies or changes its outstanding Common Stock, the successor
corporation shall enter into a supplemental indenture which 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 owned immediately after the
consolidation, merger, transfer or lease if such Holder had converted the
Security immediately before the effective date of the transaction.  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
Eleven. The successor Company shall mail to Holders a notice briefly describing
the supplemental indenture.

        If this Section applies to any such transaction, reclassification or
change, Sections 11.6 through 11.10 shall not apply thereto.

        SECTION 11.20  Trustee's Disclaimer.
                       -------------------- 

        The Trustee shall have no duty to determine whether an adjustment under
this Article Eleven or under the terms of the Securities shall be made, or if
made, whether such adjustment was properly made.  The Trustee shall have no duty
to determine whether any supplemental indenture required by Section 11.19 meets
the requirements of such Section 11.19.

        SECTION 12.1  Securities Subordinated to Senior Indebtedness.
                      ---------------------------------------------- 

        Each Holder, by accepting Securities, agrees that (a) the payment of the
principal of and interest on the Securities and (b) any payment on account of
the acquisition or redemption of the Securities by the

                                      85


Company (including, without limitation, pursuant to Section 4.10) is
subordinated to the extent and in the manner provided in this Article Twelve, to
the prior payment in full of all Senior Indebtedness of the Company and that
these subordination provisions are for the benefit of the holders of such Senior
Indebtedness.

        This Article Twelve shall constitute a continuing offer to all Persons
who become holders of, or continue to hold, Senior Indebtedness, and such
provisions are made for the benefit of the holders of Senior Indebtedness, and
such holders are made obligees hereunder and any one or more of them may enforce
such provisions.

        SECTION 12.2  No Payment on Securities in Certain Circumstances.
                      ------------------------------------------------- 

          (a)  No payment shall be made by the Company on account of the
principal of, premium, if any, or interest on the Securities or to defease or
acquire any of the Securities (including repurchases of Securities pursuant to
Section 4.10) for cash or property, or on account of the redemption provisions
of the Securities, (i) upon the maturity of any Senior Indebtedness by lapse of
time, acceleration (unless waived) or otherwise, unless and until all principal
of and interest on (including any post-petition interest) such Senior
Indebtedness and all other obligations in respect thereof shall first be paid in
full or such payment is duly provided for, or (ii) upon an event of default in
payment of any principal of, premium, if any, or interest on any Senior
Indebtedness when the same becomes due and payable, whether at maturity or at a
date fixed for prepayment or by declaration or otherwise (a "Payment Default"),
unless and until such Payment Default has been cured or waived or otherwise has
ceased to exist.

          (b)  Upon the occurrence of an event of default (other than a Payment
Default) with respect to any Senior Indebtedness, as such event of default is
defined in the instrument under which it is outstanding, permitting the holders
(or any requisite percentage thereof) to accelerate the maturity thereof or
demand payment upon written notice of such event of default given to the Company
and the Trustee by the Company holders of an aggregate of $10,000,000 principal
amount outstanding of such Senior Indebtedness or their representative (a
"Payment Notice"), then, unless and until such event of default shall have been
cured or waived or

                                      86


shall have otherwise ceased to exist, no payment shall be made by the Company on
account of the principal of or premium, if any, or interest on the Securities,
or to defease or acquire or repurchase any of the Securities for cash or
property, or on account of the redemption provisions of the Securities, in any
such case.  Notwithstanding the foregoing, unless (a) the Senior Indebtedness in
respect of which such event of default exists has been declared due and payable
in its entirety within 179 days after the Payment Notice is delivered as set
forth, above (the "Payment Blockage Period"), and (b) such declaration has not
been rescinded or waived, subject to Section 12.2(a), the Company shall be
required to pay all sums not paid to the Holders of the Securities during the
Payment Blockage Period due to the foregoing prohibitions and to resume all
other payments as and when due on the Securities.  Any number of Payment Notices
may be given; provided, however, that (i) not more than one Payment Notice shall
              --------  -------                                                 
be given within a period of any 360 consecutive days and (ii) no event of
default that existed upon the date of such Payment Notice or the commencement of
such Payment Blockage Period (whether or not such event of default is on the
same issue of Senior Indebtedness) shall be made the basis for the commencement
of any other Payment Blockage Period.

          (c)  In furtherance of the provisions of Section 12.1, in the event
that, notwithstanding the foregoing provisions of this Section 12.2, any payment
or distribution of assets of the Company on account of principal of or interest
on the Securities or to defease or acquire any of the Securities (including
repurchases of Securities pursuant to Section 4.10) for cash, property or
securities, or on account of the redemption provisions of the Securities shall
be made by the Company and received by the Trustee, by any Holder or by any
Paying Agent (or, if the Company is acting as its own Paying Agent, money for
any such payment shall be segregated and held in trust), at a time when such
payment or distribution was prohibited by the provisions of this Section 12.2,
then, unless such payment or distribution is no longer prohibited by this
Section 12.2, such payment or distribution (subject to the provisions of
Sections 12.6 and 12.7) shall be received and held in trust by the Trustee or
such Holder or Paying Agent for the benefit of the holders of Senior
Indebtedness of the Company, and shall be paid or delivered by the Trustee or
such Holders or such Paying Agent, as the case may be, to the holders of Senior
Indebtedness of the Company remaining unpaid or

indenture pursuant to which any instruments evidencing any of such Senior
Indebtedness of the Company may have been issued, ratably according to the
aggregate amounts on account of the Senior Indebtedness of the Company held or
represented by each, to the extent necessary to enable payment in full (except
as such payment otherwise shall have been provided for, of all Senior
Indebtedness of the Company remaining unpaid, after giving effect to all
concurrent payments and distributions and all provisions therefor to or for the
holders of such Senior Indebtedness, but only to the extent that as to any
holder of such Senior Indebtedness, as promptly as practical following notice
from the Trustee to the holders of such Senior Indebtedness that such prohibited
payment has been received by the Trustee, Holder(s) or Paying Agent (or has been
segregated as provided above), such holder (or a representative thereof)
notifies the Trustee of the amounts then due and owing on such Senior
Indebtedness, if any, held by such holder and only the amounts specified in such

          (c)  in the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities shall be received by the Trustee or the Holders or any
Paying Agent (or, if the Company is acting as its own Paying Agent, money for
any such payment or distribution shall be segregated or held in trust) on
account of principal of or interest on the Securities before all Senior

                                    DUE 2005
                                        

1.   Interest.
     -------- 

        M.D.C. Holdings, Inc., a Delaware corporation (the "Company"), promises
to pay interest on the principal amount of this Note at a rate of 8-3/4% per
annum. To the extent it is lawful, the Company promises to pay interest on any
interest payment due but unpaid on such principal amount at a rate of 8-3/4% per
annum compounded semi-annually.

        The Company will pay interest semi-annually on December 15 and June 15
of each year (each, an "Interest Payment Date"), commencing June 15, 1994. 
Interest on the Notes will accrue from the date of issuance or from the most
recent Interest Payment Date to which interest has been paid or provided for;
provided that, if there is no existing Default in the payment of interest and if
- --------                                                                        
this Note is authenticated between a record date referred to on the face hereof
and the next succeeding Interest Payment Date, interest shall accrue from such
Interest Payment Date.  Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months.

2.   Method of Payment.
     ----------------- 

        The Company shall pay interest on the Notes (except defaulted interest)
to the persons in whose names such Notes are registered at the close of business
on December 1 or June 1 preceding such Interest Payment Date.  Holders must
surrender Notes to a Paying Agent to collect principal payments.  Except as
provided below, the Company shall pay principal and interest in such coin or
currency of the United States of America as at the time of payment shall be
legal tender for payment of public and private debts ("U.S. Legal Tender").  At
the option of the Company, payment of interest may be made by check mailed to
the Holders of the Notes at the addresses set forth upon the registry books of
the Company.  No service charge will be made for any registration of transfer or
exchange of Notes, but the Company may require payment of a sum sufficient to
cover any tax or

                                      A-4


other governmental charge payable in connection therewith.

3.   Paying Agent, Registrar and Conversion Agent.
     -------------------------------------------- 

        Initially, First Bank National Association (the "Trustee"), will act as
Paying Agent, Registrar and Conversion Agent.  The Company may change any Paying
Agent, Registrar or Conversion Agent without notice. Subject to limitations
under certain circumstances, the Company, its Subsidiaries or Affiliates may act
as Paying Agent, Registrar, co-Registrar or Conversion Agent.

4.   Indenture.
     --------- 

        The Company issued the Notes under an Indenture, dated as of December
15, 1993 (the "Indenture"), between the Company and the Trustee.  Capitalized
terms herein are used as defined in the Indenture unless otherwise defined
herein.  The terms of the Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act, as in effect
on the date of the Indenture.  The Notes are subject to all such terms, and
Holders of Notes are referred to the Indenture and said Act for a statement of
them. The Notes are general unsecured, subordinated obligations of the Company
limited in aggregate principal amount to $50,000,000.

5.   Redemption.
     ---------- 

        The Notes may not be so redeemed before December 15, 1998.  The Notes
may be redeemed in whole or from time to time in part at any time on and after
December 15, 1998, at the option of the Company, at the Redemption Price
(expressed as a percentage of principal amount) set forth below with respect to
the indicated Redemption Date, in each case, together with any accrued but
unpaid interest, if any, to the Redemption Date.

                                      A-5



 
 
        If redeemed during
        the 12-month period
        beginning December 15     Redemption Price
        ---------------------     ----------------

        1999..................         104%
        2000..................         103%
        2001..................         102%
        2002..................         101%
        2003 and thereafter...         100%

 
        In the case of a partial redemption, the Trustee shall select the Notes
or portions thereof for redemption on a pro rata basis by lot or in such other
                                        --------                              
manner as it deems appropriate and fair.  The Notes may be redeemed in part only
in multiples of $1,000 of principal amount.

        Any such redemption will comply with Article Three of the Indenture.

6.   Notice of Redemption.
     -------------------- 

        Notice of redemption will be mailed by first class mail at least 15 days
and not more than 60 days before the Redemption Date to each Holder of Notes to
be redeemed at his address then shown upon the books of the registrar.  Notes in
denominations larger than $1,000 may be redeemed in part.  Any notice that
relates to a Note to be redeemed in part only must state the portion of the
principal amount equal to the unredeemed portion thereof and must state that on
and after the date fixed for redemption, upon surrender of such Note, a new Note
or Notes in a principal amount equal to the unredeemed portion thereof will be
issued.
  
        Except as set forth in the Indenture, from and after any Redemption
Date, if monies for the redemption of the Notes called for redemption shall have
been deposited with the Paying Agent on or before such Redemption Date, the
Notes called for redemption will cease to accrue interest and the only right of
the Holders of such Notes will be to receive payment of the Redemption Price and
any accrued and unpaid interest to the Redemption Date.

                                      A-6



7.   Denominations; Transfer; Exchange.
     --------------------------------- 

        The Notes are in registered form, without coupons, in denominations of
$1,000 and integral multiples of $1,000.  A Holder may register the transfer of,
or exchange Notes in accordance with, the Indenture.  The Registrar may require
a Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture.  The Registrar need not register the transfer of or exchange any
Notes selected for redemption.

8.   Conversion.
     ---------- 

        A Holder of a Note may convert it into Common Stock of the Company at
any time prior to the close of business on December 15, 2005, subject to prior
redemption or repurchase, to convert such Notes or portion thereof (which are
$1,000 or integral multiples thereof) into Common Stock of the Company, at the
conversion rate computed in compliance with the Indenture.  The initial
conversion rate is $7.75 principal amount of Notes for each share of Common
Stock (initially equal to 129.03 shares of Common Stock per $1,000 principal
amount of the Notes), subject to adjustment in certain events.  The Company will
deliver a check in lieu of any fractional share.  On conversion, no payment or
adjustment for interest accrued on the Notes will be made nor for dividends on
the Common Stock issued on conversion.  If any Note is converted between the
record date for the payment of interest and the next succeeding interest payment
date, such Note must be accompanied by funds equal to the interest payable on
such succeeding Interest Payment Date on the principal amount so converted
(unless such Note shall have been called for redemption, in which case no such
payment shall be required), and the interest on the principal amount of the Note
being converted will be paid on such next succeeding Interest Payment Date to
the registered holder of such Note on the immediately preceding record date
except as provided in the Indenture.  A Note converted on an Interest Payment
Date need not be accompanied by any payment, and the interest on the principal
amount of the Note being converted will be paid on such interest payment date to
the registered holder of such Note on the immediately preceding record date,
except as provided by the Indenture.

                                      A-7


        To convert a Note a Holder must (1) complete and sign the conversion
notice on the back of the Note, (2) surrender the Note to the Conversion Agent,
(3) furnish appropriate endorsements and transfer documents if required by the
Registrar or Conversion Agent and (4) pay any transfer or similar tax if
required.  A Holder may convert a portion of a Note if the portion is $1,000 or
a whole multiple of $1,000.

9.   Subordination.
     ------------- 

        The Notes are subordinated in right of payment, in the manner and to the
extent set forth in the Indenture, to the prior payment in full of all Senior
Indebtedness (as defined in the Indenture).  Each Holder by accepting a Note
agrees to such subordination and authorizes the Trustee to give it effect.

10.  Persons Deemed Owners.
     --------------------- 

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

11.  Unclaimed Money.
     --------------- 

        If money for the payment of principal or interest remains unclaimed for
two years, the Trustee and the Paying Agent(s) will pay the money back to the
Company at its written request.  After that, all liability of the Trustee and
such Paying Agent(s) with respect to such money shall cease.

12.  Discharge Prior to Redemption or Maturity.
     ----------------------------------------- 

        If the Company at any time deposits into an irrevocable trust with the
Trustee U.S. Legal Tender or U.S. Government Obligations sufficient to pay the
principal of and interest on the Notes to redemption or maturity and complies
with the other provisions of the Indenture relating thereto, the Company will be
discharged from certain provisions of the Indenture and the Notes (including the
financial covenants, but excluding, among other things, its obligation to pay
the principal of and interest on the Notes).

13.  Amendment; Supplement; Waiver.
     ----------------------------- 

        Subject to certain exceptions, the Indenture or the Notes may be amended
or supplemented with the written

                                      A-8


consent of the Holders of at least a majority in aggregate principal amount of
the Notes then outstanding, and any existing Default or Event of Default or
compliance with any provision may be waived with the consent of the Holders of a
majority in aggregate principal amount of the Notes then outstanding.  Without
notice to or consent of any Holder, the parties thereto may amend or supplement
the Indenture or the Notes to, among other things, cure any ambiguity, defect or
inconsistency, or make any other change that does not adversely affect the
rights of any Holder of a Note.

14.  Restrictive Covenants.
     --------------------- 

        The Indenture imposes certain limitations on the ability of the Company
and its Subsidiaries to, among other things, enter into transactions with
Affiliates, and a limitation on the ability of the Company to merge or
consolidate with any other Person.  The limitations are subject to many
important qualifications and exceptions.  The Company must annually report to
the Trustee on compliance with such limitations.

15.  Change of Control.
     ----------------- 

        In the event that a Change of Control (as defined in Section 4.10 of the
Indenture) has occurred, each Holder will have the right, at such Holder's
option, subject to the terms and conditions set forth in the Indenture, to
require the Company to repurchase in the manner specified in the Indenture, all
or any part (in integral multiples of $1,000) of such Holder's Notes.

16.  Successors.
     ---------- 

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

17.  Defaults and Remedies.
     --------------------- 

        If an Event of Default occurs and is continuing (other than an Event of
Default specified in Sections 6.1 (4) and (5) of the Indenture), then in every
such case, unless the principal of all of the Notes shall have already become
due and payable, either the Trustee or the Holders of 25% in aggregate principal
amount of the Notes then outstanding, by notice in writing to the Company (and
to the Trustee if given by Holders) (an "Accelera-

                                      A-9


tion Notice"), may declare all principal, determined as set forth below,
including in each case accrued interest thereon, or, as appropriate, the Change
of Control Purchase Price to be due and payable immediately.  If an Event of
Default specified in Sections 6.1 (4) or (5) of the Indenture, relating to the
Company or any of its Material Subsidiaries occurs, all principal and accrued
interest thereon will be immediately due and payable on all outstanding Notes
without any declaration or other act on the part of the Trustee or the Holders. 
Subject to certain conditions being met, the Holders of no less than a majority
in aggregate principal amount of the Notes then outstanding generally are
authorized to rescind such acceleration if all existing Events of Default, other
than the non-payment of the principal of, premium, if any, and interest on the
Notes which have become due solely by such acceleration, have been cured or
waived.  Holders may not enforce the Indenture or the Notes, except as provided
in the Indenture.

18.  No Recourse Against Others.

        No stockholder, director, officer, employee or incorporator, as such,
past, present or future, of the Company or any successor corporation shall have
any liability for any obligation of the Company under the Notes or the Indenture
or for any claim based on, in respect of or by reason of, such obligations or

all such liability.  The waiver and release are part of the consideration for
the issuance of the Notes.

signs the certificate of authentication on the other side of this Note.

        The Trustee under the Indenture, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the
