In addition, certain other terms  used herein have  definitions given to them in
the first place in which they are used.

                            SECTION 2. ADMINISTRATION

The  Corporation,  acting by and  through  its Board of  Directors,  shall  have
overall  responsibility  for the  operation  of the  Plan.  The  Plan  shall  be
administered by the Committee on Compensation and  Succession/Retirement or such
other  committee of the Board as the Board may from time to time  designate (the
"Committee"),  which  shall  be  composed  of not  less  than  two  Non-Employee
Directors,  each of whom  shall be  required  to be an  "outside  director"  for
purposes of Section  162(m)(4) of the Code,  and shall be appointed by and serve
at the pleasure of the Board.

The Committee shall have plenary authority to grant Awards pursuant to the terms
of the Plan to officers and employees of the  Corporation and its Affiliates and
Non-qualified Stock Options to Non-Employee Directors of the Corporation.

Among other things, the Committee shall have the authority, subject to the terms
of the Plan and subject to approval of the Board:

(a) To select  the  officers  and other  employees  of the  Corporation  and its
    Affiliates to whom Awards may from time to time be granted;

(b) Determine  whether and to what extent an Award or any  combination of Awards
    are to be granted hereunder;

(c) Determine  the number of shares of Common  Stock to be covered by each Award
    granted hereunder;

(d) Determine  the  terms  and   conditions  of  any  Award  granted   hereunder
    (including,  but not limited to, the option price (subject to Section 5(a)),
    any vesting  condition,  restriction or limitation  (which may be related to
    the  performance of the  participant,  the Corporation or any Affiliate) and
    any vesting  acceleration or forfeiture  waiver  regarding any Award and the
    shares  of Common  Stock  relating  thereto,  based on such  factors  as the
    Committee shall determine;

                                                                               4
<PAGE>

(e) Modify,  amend or adjust the terms and conditions of any Award,  at any time
    or from  time to time,  including  but not  limited  to  Performance  Goals;
    provided,  however,  that the  Committee  may not adjust  upwards the amount
    payable to a designated  Covered Employee with respect to a particular Award
    upon the satisfaction of applicable Performance Goals;

(f) Determine to what extent and under what circumstances Common Stock and other
    amounts payable with respect to an Award shall be deferred; and

(g) Determine under what  circumstances  and/or in what proportions an Award may
    be settled in cash or Common Stock under Sections 5(j) and 8(b)(i).

The  Committee  shall  have the  authority  to  adopt,  alter  and  repeal  such
administrative  rules,  guidelines and practices  governing the Plan as it shall
from time to time deem  advisable,  to interpret the terms and provisions of the
Plan and any Award issued under the Plan (and any  agreement  relating  thereto)
and to otherwise supervise the administration of the Plan.

The Committee  may act only by a majority of its members then in office,  except
that the members  thereof may (i) delegate to an officer of the  Corporation the
authority to make decisions pursuant to paragraphs (c), (f), (g), (h) and (i) of
Section 5  (provided  that no such  delegation  may be made that would cause any
Award or transaction  under the Plan to cease to be exempt from Section 16(b) of
the  Exchange  Act or cause any Award or payment  made in respect  thereof to be
"applicable  employee  remuneration" under Section 162(m)(4)(A) of the Code) and
(ii) authorize any one or more of their number or any officer of the Corporation
to execute and deliver documents on behalf of the Committee.

Any  determination  made by the  Committee  or pursuant to  delegated  authority
pursuant to the  provisions  of the Plan with respect to any Award shall be made
in the sole  discretion  of the  Committee  or such  delegate at the time of the
grant of the Award or, unless in  contravention of any express term of the Plan,
at any time thereafter. All decisions made by the Committee or any appropriately
delegated  officer  pursuant  to the  provisions  of the Plan shall be final and
binding on all persons, including the Corporation and Plan participants, subject
to the next paragraph.

The Committee annually shall report to the Corporation's Board of Directors with
respect to the operation of the Plan and at least  annually shall meet with such
Board to review the  Committee's  acts and  determinations  with  respect to the
Plan. The Board of Directors of the  Corporation  shall have the right to review
any  decision,  act or  determination  made by the  Committee and shall have the
right  to  amend,  modify,   reverse  or  rescind  any  such  decision,  act  or
determination,  which Board  action  shall be final and binding on all  persons,
including the Corporation and Plan participants.

                     SECTION 3. COMMON STOCK SUBJECT TO PLAN

The total number of shares of Common  Stock  reserved  and  available  for grant
under the Plan shall be 500,000,  no more than 50,000 of which  shares  shall be
granted as Awards of Restricted Stock which do not have Performance Goals as the
sole or partial  conditions for vesting.  No  participant  may be granted Awards
covering in excess of 150,000 shares of

                                                                               5
<PAGE>

Common  Stock  over  the life of the  Plan,  including  Awards  that  expire  or
terminate  unexercised.  Shares  subject  to an  Award  under  the  Plan  may be
authorized and unissued  shares or may be treasury shares or may be purchased on
the open market or any combination thereof.

Any  shares  subject  to an Award  under the Plan,  which  Award for any  reason
expires or is terminated  unexercised as to such shares,  shall,  subject to the
provisions of the previous  paragraph  that may restrict  their  reissuance to a
particular  participant,  again be available for the grant of other Awards under
the Plan.

Subject to Sections  7(c)(iv) and 9(b) (iii), if any shares of Restricted  Stock
or  Performance  Shares are  forfeited or if any Stock Option (and related Stock
Appreciation Right, if any) terminates without being exercised,  or if any Stock
Appreciation  Right is exercised for cash,  shares subject to such Awards shall,
subject  to the  provisions  of the first  paragraph  of this  section  that may
restrict their distribution to a particular participant,  again be available for
distribution in connection with Awards under the Plan.

In the event of any change in corporate capitalization, such as a stock split or
a  corporate  transaction,  such  as  any  merger,  consolidation,   separation,
including  a  spin-off,  or  other  distribution  of stock  or  property  of the
Corporation, any reorganization (whether or not such reorganization comes within
the  definition  of such  term in  Section  368 of the Code) or any  partial  or
complete liquidation of the Corporation (_Corporate Transaction_), the Committee
or Board may make such  substitution or adjustments in the aggregate  number and
kind of shares  reserved for issuance  under the Plan,  in the number,  kind and
option  price  of  shares  subject  to  outstanding   Stock  Options  and  Stock
Appreciation  Rights,  in the  number  and  kind  of  shares  subject  to  other
outstanding   Awards  granted  under  the  Plan  and/or  such  other   equitable
substitution  or  adjustments  as it may determine to be appropriate in its sole
discretion;  provided  however,  that the number of shares  subject to any Award
shall always be a whole number. Such adjusted option price shall also be used to
determine the amount payable by the  Corporation  upon the exercise of any Stock
Appreciation Right associated with any Stock Option.

                             SECTION 4. ELIGIBILITY

Officers  and other  employees of the  Corporation  and its  Affiliates  who are
responsible  for  or  contribute  to  the  management,  governance,  growth  and
profitability  of the business of the Corporation or its Affiliates are eligible
to be granted  Awards under the Plan. No grants shall be made under this Plan to
a Director who is not an officer or a salaried  employee of the  Corporation  or
its  Affiliates,  except  that  Non-qualified  Stock  Options  may be granted to
Non-Employee Directors.

                                                                               6
<PAGE>

                            SECTION 5. STOCK OPTIONS

Stock Options may be granted alone or in addition to other Awards  granted under
the Plan and may be of two types,  Incentive  Stock  Options  and  Non-qualified
Stock Options.  Any Stock Option granted under the Plan shall be in such form as
the Committee may from time to time approve.

The  Committee  shall have the authority to grant any optionee  Incentive  Stock
Options,  Non-qualified  Stock  Options or both types of Stock  Options (in each
case with or without Stock Appreciation  Rights);  provided however, that grants
hereunder  are  subject  to  the   aggregate   limit  on  grants  to  individual
participants set forth in Section 3. Incentive Stock Options may be granted only
to  employees  of the  Corporation  and its  Affiliates  (within  the meaning of
Section  424(f)  of the  Code).  To the  extent  that any  Stock  Option  is not
designated  as an  Incentive  Stock  Option  or even if so  designated  does not
qualify as an Incentive Stock Option, it shall constitute a Non-qualified  Stock
Option.

Stock Options shall be evidenced by option agreements,  the terms and provisions
of which may differ.  An option  agreement shall indicate on its face whether it
is intended to be an agreement for an Incentive  Stock Option or a Non-qualified
Stock  Option.  The grant of a Stock Option shall occur on the date on which the
Committee by resolution  selects an individual to be a participant  in any grant
of a Stock Option, determines the number of shares of Common Stock to be subject
to such Stock Option to be granted to such  individual  and  specifies the terms
and provisions of the Stock Option.  The Corporation  shall notify a participant
of any grant of a Stock  Option,  and a written  option  agreement or agreements
shall be duly executed and delivered by the Corporation to the participant. Such
agreement or agreements shall become effective upon execution by the Corporation
and the participant.

Anything  in the  Plan to the  contrary  notwithstanding,  no  term of the  Plan
relating to Incentive Stock Options shall be interpreted, amended or altered nor
shall any  discretion or authority  granted under the Plan be exercised so as to
disqualify the Plan under Section 422 of the Code or, without the consent of the
optionee  affected,  to disqualify any Incentive Stock Option under said Section
422.

Stock Options granted under the Plan shall be subject to the following terms and
conditions  and  shall  contain  such  additional  terms and  conditions  as the
Committee shall deem desirable:

(a)  Option Price. The option price per share of Common Stock  purchasable under
     a Stock Option shall be  determined  by the  Committee and set forth in the
     option  agreement,  but shall not be less than the Fair Market Value of the
     Common Stock subject to the Stock Option on the date of grant.

(b)  Option Term. The term of each Stock Option shall be fixed by the Committee,
     but no Incentive Stock Option shall be exercisable more than ten (10) years
     after the date on which the Stock Option is granted.

                                                                               7
<PAGE>

(c)  Exercisability.  Except as otherwise  provided  herein and in Section 5A(c)
     specifically,  Stock Options shall be exercisable at such time or times and
     subject  to such  terms  and  conditions  as  shall  be  determined  by the
     Committee.  If the Committee  provides that any Stock Option is exercisable
     only in installments,  the Committee may at any time waive such installment
     exercise  provisions,  in whole or in part,  based on such  factors  as the
     Committee  may  determine.  In  addition,  the  Committee  may at any  time
     accelerate the exercisability of any Stock Option.

(d)  Method of  Exercise.  Subject to the  provisions  of this  Section 5, Stock
     Options  may be  exercised,  in whole or in part,  at any time  during  the
     option  term by  giving  written  notice  of  exercise  to the  Corporation
     specifying the number of shares of Common Stock subject to the Stock Option
     to be purchased.

     Such notice shall be  accompanied  by payment in full of the purchase price
     by certified or bank check or such other  instrument as the Corporation may
     accept. If approved by the Committee, payment, in full or in part, may also
     be made in the  form of  unrestricted  Common  Stock  already  owned by the
     optionee  (based on the Fair Market  Value of the Common  Stock on the date
     the Stock Option is exercised)  and which has been held by the optionee for
     at  least  six  (6)  months;  provided  however,  that,  in the  case of an
     Incentive Stock Option,  the right to make a payment in the form of already
     owned shares of Common Stock may be  authorized  only at the time the Stock
     Option is granted.

     In the  discretion of the  Committee,  payment for any shares  subject to a
     Stock Option may also be made by  delivering a properly  executed  exercise
     notice to the Corporation, together with a copy of irrevocable instructions
     to a broker to deliver  promptly to the  Corporation  the amount of sale or
     loan proceeds to pay the purchase price,  and, if requested,  by the amount
     of any federal,  state,  local or foreign  withholding taxes. To facilitate
     the foregoing,  the  Corporation  may enter into agreements for coordinated
     procedures with one or more brokerage firms.

     In addition,  in the  discretion of the  Committee,  payment for any shares
     subject to a Stock Option may also be made by instructing  the Committee to
     withhold a number of such shares  having a Fair Market Value on the date of
     exercise equal to the aggregate exercise price of such Stock Option.

     No shares of Common Stock shall be issued  until full payment  therefor has
     been made. An optionee shall have all of the rights of a shareholder of the
     Corporation  holding the class or series of Common Stock that is subject to
     such Stock Option (including,  if applicable,  the right to vote the shares
     and the right to receive  dividends),  when the optionee has given  written
     notice of exercise, has paid in full for such shares and, if requested, has
     given the representation described in Section 13 (a).

(e)  Nontransferability  of Stock Options. No Stock Option shall be transferable
     by the  optionee  other  than  (i) by will or by the  laws of  descent  and
     distribution; or (ii) in the case of a Non-qualified Stock Option, pursuant
     to (a) a  qualified  domestic  relations  order (as  defined in the Code or
     Title I of the Employee Retirement Income Security Act of 1974, as amended,
     or the rules thereunder) or (b) a gift to such optionee's

                                                                               8

     children,  whether  directly  or  indirectly  or by  means  of a  trust  or
     partnership  or  otherwise,  if expressly  permitted  under the  applicable
     option  agreement.  All Stock Options shall be exercisable,  subject to the
     terms of this Plan, during the optionee's lifetime, only by the optionee or
     by the guardian or legal  representative of the optionee or, in the case of
     a  Non-qualified  Stock  Option,  its  alternative  payee  pursuant to such
     qualified  domestic  relations  order or the recipient of a gift  permitted
     under the applicable option  agreement,  it being understood that the terms
     "holder" and "optionee"  include the guardian and legal  representative  of
     the optionee named in the option agreement and any person to whom an option
     is transferred by will or the laws of descent and  distribution  or, in the
     case of a  Non-qualified  Stock  Option,  pursuant to a qualified  domestic
     relations order or a gift permitted under the applicable option agreement.

(f)  Termination by Death. Unless otherwise  determined by the Committee,  if an
     optionee's  employment terminates by reason of death, any Stock Option held
     by such optionee may  thereafter be exercised in full,  whether or not then
     exercisable,  or on such accelerated  basis as the Committee may determine,
     for a period of three (3) years (or such other period as the  Committee may
     specify in the option  agreement)  from the date of such death or until the
     expiration of the stated term of such Stock Option, whichever period is the
     shorter.

(g)  Termination by Reason of  Disability.  Unless  otherwise  determined by the
     Committee,  if an optionee's employment terminates by reason of Disability,
     any Stock Option held by such  optionee may  thereafter be exercised by the
     optionee,  to the extent it was exercisable at the time of termination,  or
     on such accelerated  basis as the Committee may determine,  for a period of
     three (3) years (or such shorter period as the Committee may specify in the
     option  agreement) from the date of such termination of employment or until
     the expiration of the stated term of such Stock Option, whichever period is
     the  shorter;  provided  however,  that if the  optionee  dies  within such
     period,   any  unexercised  Stock  Option  held  by  such  optionee  shall,
     notwithstanding  the expiration of such period,  continue to be exercisable
     to the extent to which it was exercisable at the time of death for a period
     of one (1) year from the date of such death or until the  expiration of the
     stated term of such Stock Option,  whichever period is the shorter.  In the
     event of termination of employment by reason of Disability, if an Incentive
     Stock Option is exercised after the expiration of the exercise periods that
     apply for  purposes  of Section  422 of the Code,  such Stock  Option  will
     thereafter be treated as a Non-qualified Stock Option.

(h)  Termination by Reason of  Retirement.  Except as provided for in Section 5A
     hereof and unless otherwise  determined by the Committee,  if an optionee's
     employment  terminates  by reason of  Retirement,  any Stock Option held by
     such optionee may thereafter be exercised by the optionee, to the extent it
     was  exercisable  at the time of such  Retirement,  or on such  accelerated
     basis as the  Committee may  determine,  for a period of five (5) years (or
     such shorter  period as the Committee may specify in the option  agreement)
     from the date of such  termination of employment or until the expiration of
     the stated  term of such Stock  Option,  whichever  period is the  shorter;
     provided  however,  that if the  optionee  dies  within  such  period,  any
     unexercised Stock Option held by such optionee shall,  notwithstanding  the
     expiration  of such  period,  continue to be  exercisable  to the extent to
     which it was

                                                                               9
<PAGE>

     exercisable  at the time of death for a period of twelve  (12)  months from
     the date of such death or until the  expiration  of the stated term of such
     Stock Option,  whichever period is the shorter. In the event of termination
     of  employment  by reason of  Retirement,  if an Incentive  Stock Option is
     exercised  after the  expiration  of the  exercise  periods  that apply for
     purposes of Section 422 of the Code,  such Stock Option will  thereafter be
     treated as a Non-qualified Stock Option.

(i)  Other Termination.  Unless otherwise determined by the Committee: (A) If an
     optionee  incurs a Termination of Employment  for Cause,  all Stock Options
     held by such optionee  shall  thereupon  terminate;  and (B) If an optionee
     incurs a  Termination  of  Employment  for any  reason  other  than  death,
     Disability  or  Retirement  or for  Cause,  any Stock  Option  held by such
     optionee,  to the extent then exercisable,  or on such accelerated basis as
     the Committee may  determine,  may be exercised for the lesser of three (3)
     months from the date of such  Termination  of  Employment or the balance of
     such Stock  Option's  term;  provided  however,  that if the optionee  dies
     within such three (3)-month  period,  any unexercised  Stock Option held by
     such optionee shall, notwithstanding the expiration of such three (3)-month
     period,  continue  to  be  exercisable  to  the  extent  to  which  it  was
     exercisable  at the time of death for a period of twelve  (12)  months from
     the date of such death or until the  expiration  of the stated term of such
     Stock  Option,  whichever  period  is  the  shorter.   Notwithstanding  the
     foregoing,  if an optionee incurs a Termination of Employment at or after a
     Change of  Control  (as  defined  Section  10(b)),  other than by reason of
     death,  Disability  or  Retirement,  any Stock Option held by such optionee
     shall be  exercisable  for the lesser of (i) six (6) months and one (1) day
     from the date of such  Termination of  Employment,  and (ii) the balance of
     such Stock Option's term. In the event of Termination of Employment,  if an
     Incentive  Stock Option is exercised  after the  expiration of the exercise
     periods  that apply for  purposes  of Section  422 of the Code,  such Stock
     Option will thereafter be treated as a Non-qualified Stock Option.

(j)  Cashing Out of Stock  Option.  Upon receipt of written  notice of exercise,
     the  Committee  may  elect  to cash out all or part of the  portion  of the
     shares of  Common  Stock for  which a Stock  Option is being  exercised  by
     paying the optionee an amount, in cash or Common Stock, equal to the excess
     of the Fair Market  Value of the Common  Stock over the option  price times
     the  number  of shares  of  Common  Stock  for  which  the  Option is being
     exercised on the effective date of such cash-out.

(k)  Change of Control  Cash-Out.  Notwithstanding  any other  provision  of the
     Plan,  during the  60-day  period  from and after a Change of Control  (the
     "Exercise  Period"),  unless the Committee shall determine otherwise at the
     time of grant,  an optionee shall have the right,  whether or not the Stock
     Option is fully  exercisable  and in lieu of the  payment  of the  exercise
     price for the shares of Common Stock being purchased under the Stock Option
     and by giving  notice to the  Corporation,  to elect  (within the  Exercise
     Period) to surrender all or part of the Stock Option to the Corporation and
     to receive cash,  within 30 days of such notice,  in an amount equal to the
     amount by which the  Change of Control  Price per share of Common  Stock on
     the date of such  election  shall  exceed the  exercise  price per share of
     Common Stock under the Stock Option (the "Spread") multiplied by the number
     of shares of Common  Stock  granted  under the Stock Option as to which the
     right granted under

                                                                              10
<PAGE>

     this Section 5(k) shall have been exercised.

(l)  Notwithstanding anything in the Plan to the contrary, no Stock Option shall
     be reissued or repriced.

                     SECTION 5A. STOCK OPTIONS FOR DIRECTORS

Each Non-Employee  Director shall annually be granted 1,000  Non-qualified Stock
Options  on January 1 of each year,  except  that in January  2001 the number of
such  Non-Qualified  Stock Options granted shall be increased by 2,000. No other
Awards under this Plan shall be granted to a Non-Employee Director.

Each such  Non-qualified  Stock  Option  grant shall be  evidenced  by an option
agreement  and shall be subject to the same terms and  conditions  applicable to
Non-Qualified Stock Options grants under the Plan and to the optionee recipients
thereof, except as follows:

(a)  the option  price per share of Common  Stock shall be the Fair Market Value
     of the Common Stock subject to the  Non-Qualified  Stock Option on the date
     of grant;

(b)  the term of each such  Non-Qualified  Stock Option shall be ten (10) years;
     and

(c)  each Non-qualified Stock Option awarded to Non-Employee  Directors shall be
     exercisable on and after the date of grant.

Any reference in this Plan to  "Retirement"  (Normal or Early  Retirement),  and
"termination  of  Employment",  and  "employment  terminates"  shall mean when a
Non-Employee Director optionee ceases to be a Director of the Corporation.

                      SECTION 6. STOCK APPRECIATION RIGHTS

(a)  Grant and Exercise. Stock Appreciation Rights may be granted in conjunction
     with all or part of any Stock Option granted under the Plan. In the case of
     a Non-qualified Stock Option, such rights may be granted either at or after
     the time of grant of such Stock Option.  In the case of an Incentive  Stock
     Option,  such rights may be granted only at the time of grant of such Stock
     Option.  A Stock  Appreciation  Right  shall  terminate  and no  longer  be
     exercisable upon the termination or exercise of the related Stock Option.

     A Stock  Appreciation  Right may be exercised by an optionee in  accordance
     with Section 6(b) by  surrendering  the  applicable  portion of the related
     Stock Option in accordance  with  procedures  established by the Committee.
     Upon such exercise and surrender, the optionee shall be entitled to receive
     an amount  determined  in the  manner  prescribed  in Section  6(b).  Stock
     Options which have been so surrendered

                                                                              11
<PAGE>

     shall no longer be exercisable to the extent the related Stock Appreciation
     Rights have been exercised.

(b)  Terms and Conditions.  Stock  Appreciation  Rights shall be subject to such
     terms and conditions as shall be determined by the Committee, including the
     following:

     (i)    Stock Appreciation  Rights shall be exercisable only at such time or
            times and to the extent that the Stock  Options to which they relate
            are exercisable in accordance with the provisions Section 5 and this
            Section 6.

     (ii)   Upon the exercise of a Stock  Appreciation  Right, an optionee shall
            be entitled to receive an amount in cash,  shares of Common Stock or
            both,  equal in value to the excess of the Fair Market  Value of one
            share of Common Stock over the option  price per share  specified in
            the  related  Stock  Option  multiplied  by the  number of shares in
            respect  of which  the  Stock  Appreciation  Right  shall  have been
            exercised, with the Committee having the right to determine the form
            of payment.

     (iii)  Stock  Appreciation  Rights shall be transferable  only to permitted
            transferees  of the  underlying  Stock  Option  in  accordance  with
            Section 5(e).

     (iv)   Upon the exercise of a Stock Appreciation Right, the Stock Option or
            part thereof to which such Stock Appreciation Right is related shall
            be deemed to have been  exercised for the purpose of the  limitation
            set forth in Section 3 on the number of shares of Common Stock to be
            issued  under the  Plan,  but only to the  extent  of the  number of
            shares  covered  by the  Stock  Appreciation  Right  at the  time of
            exercise based on the value of the Stock  Appreciation Right at such
            time.

                           SECTION 7. RESTRICTED STOCK

(a)  Administration.  Shares of Restricted  Stock may be awarded either alone or
     in addition to other Awards  granted under the Plan.  The  Committee  shall
     determine  the officers  and other  employees  of the  Corporation  and its
     Affiliates  to whom and the time or times  at which  grants  of  Restricted
     Stock  will  be  awarded,  the  number  of  shares  to be  awarded  to  any
     participant  (subject  to the  aggregate  limit  on  grants  to  individual
     participants set forth in Section 3), the conditions for vesting,  the time
     or times  within  which such  Awards may be subject to  forfeiture  and any
     other terms and conditions of the Awards, in addition to those contained in
     Section 7(c).

     The Committee may, prior to grant,  condition  vesting of Restricted  Stock
     upon the attainment of Performance Goals. The Committee may, in addition to
     requiring  satisfaction of Performance  Goals,  condition  vesting upon the
     continued  service of the  participant.  The provisions of Restricted Stock
     Awards  (including the applicable  Performance  Goals) need not be the same
     with respect to each recipient.  All Performance Goals applicable to Awards
     of  Restricted  Stock  shall be  approved  by the  Committee  in writing as
     required by Section 162(m) of the Code and the rules

                                                                              12
<PAGE>

     and regulations  thereunder in order for the value of the Restricted  Stock
     delivered pursuant to such Award to be deductible.

(b)  Awards and  Certificates.  Shares of Restricted Stock shall be evidenced in
     such manner as the Committee may deem  appropriate,  including  book- entry
     registration or issuance of one or more stock certificates. Any certificate
     issued in respect of shares of Restricted  Stock shall be registered in the
     name of such participant and shall bear an appropriate  legend referring to
     the  terms,   conditions  and   restrictions   applicable  to  such  Award,
     substantially in the following form:

       "THE  TRANSFERABILITY  OF  THIS  CERTIFICATE  AND  THE  SHARES  OF  STOCK
     REPRESENTED  HEREBY  ARE  SUBJECT  TO THE TERMS AND  CONDITIONS  (INCLUDING
     FORFEITURE) OF CH ENERGY GROUP, INC. LONG-TERM  PERFORMANCE-BASED INCENTIVE
     PLAN AND A RESTRICTED  STOCK  AGREEMENT.  COPIES OF SUCH PLAN AND AGREEMENT
     ARE ON FILE AT THE OFFICES OF THE SECRETARY OF CH ENERGY GROUP,  INC.,  284
     SOUTH AVENUE, POUGHKEEPSIE, NEW YORK."

     The Committee may require that the  certificates  evidencing such shares be
     held in custody by the  Corporation  until the  restrictions  thereon shall
     have lapsed and that, as a condition of any Award of Restricted  Stock, the
     participant shall have delivered a stock power, endorsed in blank, relating
     to the Common Stock covered by such Award.

(c)  Terms and  Conditions.  Shares of Restricted  Stock shall be subject to the
     following terms and conditions:

     (i)    Subject  to the  provisions  of the  Plan and the  Restricted  Stock
            Agreement  referred to in Section  7(c)(vi),  during the period,  if
            any, set by the  Committee,  commencing  with the date of such Award
            for which such  participant's  continued  service is  required  (the
            "Restriction  Period"), and until the later of (i) the expiration of
            the Restriction Period and (ii) the date the applicable  Performance
            Goals (if any) are satisfied, the participant shall not be permitted
            to sell,  assign,  transfer,  pledge or otherwise encumber shares of
            Restricted Stock;  provided,  that the foregoing shall not prevent a
            participant  from pledging  Restricted Stock as security for a loan,
            the sole  purpose  of which is to  provide  funds to pay the  option
            price for Stock  Options.  Within these  limits,  the  Committee may
            provide for the lapse of  restrictions  based upon period of service
            in  installments  or otherwise and may accelerate or waive, in whole
            or in part,  restrictions  based  upon  period  of  service  or upon
            performance;  provided however, that in the case of Restricted Stock
            subject  to  Performance  Goals  granted to a  participant  who is a
            Covered  Employee,   the  applicable  Performance  Goals  have  been
            satisfied.

     (ii)   Except as provided in this  paragraph  (ii) and Section  7(c)(i) and
            the Restricted  Stock  Agreement,  the participant  shall have, with
            respect to the shares of  Restricted  Stock,  all of the rights of a
            shareholder of the Corporation holding the class or series of Common
            Stock that is the subject of the  Restricted  Stock,  including,  if
            applicable, the right to vote the shares

                                                                              13
<PAGE>

            and the right to receive any cash dividends. If so determined by the
            Committee in the applicable  Restricted  Stock Agreement and subject
            to Section  13(e) of the Plan,  (1) cash  dividends  on the class or
            series of Common Stock that is the subject of the  Restricted  Stock
            Award shall be  automatically  deferred and reinvested in additional
            Restricted   Stock,  held  subject  to  vesting  of  the  underlying
            Restricted  Stock,  or held  subject  to meeting  Performance  Goals
            applicable  only to dividends,  and (2) dividends  payable in Common
            Stock  shall  be paid in the  form of  Restricted  Stock of the same
            class as the Common Stock with which such  dividend  was paid,  held
            subject to vesting of the underlying  Restricted Stock,  and/or held
            subject to meeting Performance Goals applicable only to dividends.

     (iii)  Except to the extent otherwise provided in the applicable Restricted
            Stock Agreement and Sections 7(c)(i), 7(c)(iv) and 10(a)(ii), upon a
            participant's  Termination  of Employment  for any reason during the
            Restriction  Period or before the applicable  Performance  Goals are
            satisfied,   all  shares  still  subject  to  restriction  shall  be
            forfeited by the participant.

     (iv)   Except to the extent otherwise provided in Section 10(a)(ii), in the
            event that a participant retires or such participant's employment is
            involuntarily terminated (other than for Cause), the Committee shall
            have the  discretion  to  waive,  in  whole  or in part,  any or all
            remaining  restrictions (other than, in the case of Restricted Stock
            with  respect  to  which  a  participant  is  a  Covered   Employee,
            satisfaction  of  any  applicable   Performance   Goals  unless  the
            participant's  employment  is  terminated  by  reason  of  death  or
            Disability) with respect to any or all of such participant's  shares
            of Restricted Stock.

     (v)    If and when any applicable  Performance  Goals are satisfied and the
            Restriction  Period  expires  without  a  prior  forfeiture  of  the
            Restricted Stock,  unlegended  certificates for such shares shall be
            delivered  to  the  participant   upon  surrender  of  the  legended
            certificates.

     (vi)   Each Award shall be confirmed  by, and be subject to, the terms of a
            Restricted Stock Agreement.

                          SECTION 8. PERFORMANCE UNITS

(a)  Administration.  Performance  Units  may  be  awarded  either  alone  or in
     addition  to other  Awards  granted  under the Plan.  The  Committee  shall
     determine  the officers  and other  employees  of the  Corporation  and its
     Affiliates to whom and the time or times at which  Performance  Units shall
     be  awarded,  the  number  of  Performance  Units  to  be  awarded  to  any
     participant  (subject  to the  aggregate  limit  on  grants  to  individual
     participants  set forth in Section 3), the  duration of the Award Cycle and
     any other terms and conditions of the Award, in addition to those contained
     in Section 8(b).

                                                                              14
<PAGE>

     The Committee may, prior to grant,  condition the settlement of Performance
     Units upon continued employment and/or the attainment of Performance Goals.
     The provisions of such Awards (including the applicable  Performance Goals)
     need not be the same with respect to each recipient.  All Performance Goals
     applicable to Awards of  Performance  Units  awarded  during an Award Cycle
     shall be approved by the Committee in writing as required by Section 162(m)
     of the Code and the rules and regulations  thereunder in order for the cash
     and/or property delivered pursuant to such Award to be deductible.

(b)  Terms and  Conditions.  Performance  Units  Awards  shall be subject to the
     following terms and conditions:

     (i)    Subject  to the  provisions  of the Plan and the  Performance  Units
            Agreement referred to in Section 8(b)(vi), Performance Units may not
            be sold,  assigned,  transferred,  pledged or  otherwise  encumbered
            during the Award Cycle.  At the  expiration of the Award Cycle,  the
            Committee shall evaluate the  Corporation's  performance in light of
            the Performance Goals for such Award to the extent  applicable,  and
            shall  determine  the  value of  Performance  Units  granted  to the
            participant which have been earned, and the Committee may then elect
            to deliver (1) the cash amount  equal to the value and number of the
            Performance  Units  determined by the Committee to have been earned,
            or (2) the number of shares of Common  Stock whose Fair Market Value
            is  equal  to  cash  value  and  number  of  the  Performance  Units
            determined by the Committee to have been earned the participant. The
            maximum  value of cash  and/or  property  that any  participant  may
            receive with respect to Performance Units in any year is $600,000.

     (ii)   Except  to  the  extent   otherwise   provided  in  the   applicable
            Performance  Unit Agreement and Sections  8(b)(iii) and  10(a)(iii),
            upon a participant's Termination of Employment for any reason during
            the  Award  Cycle or before  any  applicable  Performance  Goals are
            satisfied, the rights to the shares still covered by the Performance
            Units Award shall be forfeited by the participant.

     (iii)  Except to the extent otherwise  provided in Section  10(a)(iii),  in
            the event that a participant's  employment is terminated (other than
            for  Cause) or in the event a  participant  retires,  the  Committee
            shall have the discretion to waive,  in whole or in part, any or all
            remaining   payment   limitations   (other  than,  in  the  case  of
            Performance  Units with respect to which a participant  is a Covered
            Employee,  satisfaction of any applicable  Performance  Goals unless
            the  participant's  employment  is  terminated by reason of death or
            Disability)  with  respect  to  any or  all  of  such  participant's
            Performance Units.

     (iv)   A participant  may elect to further defer receipt of the Performance
            Units payable under an Award (or an  installment  of an Award) for a
            specified period or until a specified event, subject in each case to
            the Committee's  approval and to such terms as are determined by the
            Committee  (the  "Elective  Deferral  Period").  Such  election must
            generally be made prior to  commencement  of the Award Cycle for the
            Award (or for such installment of an Award).

                                                                              15

     (v)    If and when any applicable  Performance  Goals are satisfied and the
            Elective  Deferral Period expires without a prior  forfeiture of the
            Performance Units, payment in accordance with Section 8(b)(i) hereof
            shall be made to the participant.

     (vi)   Each Award shall be confirmed  by, and be subject to, the terms of a
            Performance Unit Agreement.

                          SECTION 9. PERFORMANCE SHARES

(a)  Administration.  Performance  Shares  may be  awarded  either  alone  or in
     addition  to other  Awards  granted  under the Plan.  The  Committee  shall
     determine  the officers  and other  employees  of the  Corporation  and its
     Affiliates to whom and the time or times at which Performance  Shares shall
     be  awarded,  the  number  of  Performance  Shares  to be  awarded  to  any
     participant  (subject  to the  aggregate  limit  on  grants  to  individual
     participants  set forth in Section 3), the  duration of the Award Cycle and
     any other terms and conditions of the Award, in addition to those contained
     in Section 9(b).

     The Committee may, prior to grant,  condition the settlement of Performance
     Shares upon  continued  employment  and/or the  attainment  of  Performance
     Goals. The provisions of such Awards (including the applicable  Performance
     Goals) need not be the same with respect to each recipient. All Performance
     Goals  applicable to Awards of  Performance  Shares awarded during an Award
     Cycle shall be approved by the  Committee in writing as required by Section
     162(m) of the Code and the rules and  regulations  thereunder  in order for
     the  property  delivered  pursuant  to such Award to be  deductible  by the
     Corporation under the Code.

(b)  Terms and  Conditions.  Performance  Shares  Awards shall be subject to the
     following terms and conditions:

     (i)    Subject to the  provisions  of the Plan and the  Performance  Shares
            Agreement  referred to in Section 9(b)(vi),  Performance  Shares may
            not be sold, assigned, transferred,  pledged or otherwise encumbered
            during the Award Cycle.  At the  expiration of the Award Cycle,  the
            Committee shall evaluate the  Corporation's  performance in light of
            the Performance Goals for such Award to the extent  applicable,  and
            shall  determine  the value and  number of  Performance  Shares  and
            associated  reinvested  dividends earned by the  participant.  If so
            determined by the  Committee in the  applicable  Performance  Shares
            Agreement  and  subject  to  Section  13(e)  of the  Plan,  (1) cash
            dividends on the class or series of Common Stock that is the subject
            of the Performance  Share Award shall be automatically  deferred and
            reinvested  in additional  shares of Common  Stock,  held subject to
            vesting of the  underlying  Performance  Shares,  or held subject to
            meeting  Performance  Goals , and (2)  dividends  payable  in Common
            Stock  shall be paid in the form of shares  of  Common  Stock of the
            same class as the Common  Stock with which such  dividend  was paid,
            held subject to vesting of the underlying

                                                                              16
<PAGE>

            Performance  Shares,  or held  subject  to meeting  the  Performance
            Goals.  The  maximum  value of  property  that any  participant  may
            receive with respect to Performance  Shares in any year is $600,000.
            Delivery to the participant will be in shares of Common Stock only.

     (ii)   Except  to  the  extent   otherwise   provided  in  the   applicable
            Performance  Unit Agreement and Sections  9(b)(iii) and  10(a)(iii),
            upon a participant's Termination of Employment for any reason during
            the  Award  Cycle or before  any  applicable  Performance  Goals are
            satisfied, the rights to the shares still covered by the Performance
            Shares Award shall be forfeited by the participant.

     (iii)  Except to the extent otherwise  provided in Section  10(a)(iii),  in
            the event that a participant's  employment is terminated (other than
            for  Cause) or in the event a  participant  retires,  the  Committee
            shall have the discretion to waive,  in whole or in part, any or all
            remaining   payment   limitations   (other  than,  in  the  case  of
            Performance  Shares with respect to which a participant is a Covered
            Employee,  satisfaction of any applicable  Performance  Goals unless
            the  participant's  employment  is  terminated by reason of death or
            Disability)  with  respect  to  any or  all  of  such  participant's
            Performance Shares.

     (iv)   A participant  may elect to further defer receipt of the Performance
            Shares  payable under an Award (or an installment of an Award) for a
            specified period or until a specified event, subject in each case to
            the Committee's  approval and to such terms as are determined by the
            Committee (the "Elective  Deferral  Period").  Such election must be
            made prior to  commencement of the Award Cycle for the Award (or for
            such installment of an Award).

     (v)    If and when any applicable  Performance  Goals are satisfied and the
            Elective  Deferral Period expires without a prior  forfeiture of the
            Performance  Shares,  payment in  accordance  with  Section  9(b)(i)
            hereof shall be made to the participant.

     (vi)   Each Award shall be confirmed  by, and be subject to, the terms of a
            Performance Unit Agreement.

                    SECTION 10. CHANGE OF CONTROL PROVISIONS

(a)  Impact of Event.  Notwithstanding  any other  provision  of the Plan to the
     contrary, in the event of a Change of Control:

     (i)    Any Stock Options and Stock  Appreciation  Rights  outstanding as of
            the date such Change of Control is determined to have occurred,  and
            which  are not then  exercisable  and  vested,  shall  become  fully
            exercisable and vested to the full extent of the original grant.

                                                                              17
<PAGE>

     (ii)   The  restrictions  and  deferral   limitations   applicable  to  any
            Restricted Stock shall lapse, and such Restricted Stock shall become
            free of all restrictions and become fully vested and transferable to
            the full extent of the original grant.

     (iii)  All Performance  Shares shall be considered to be earned and payable
            to the extent that any  Performance  Goals which the Committee shall
            establish  have  been met or  exceeded,  and any  deferral  or other
            restriction shall lapse and such Performance Shares shall be settled
            in cash as promptly as is practicable.

(b)  Definition  of Change of Control.  For  purposes of the Plan,  a "Change of
     Control" shall mean the happening of any of the following events:

     (i)    The  acquisition  by any  individual,  entity or group  (within  the
            meaning of Section  13(d)(3) or 14(d)(2) of the Securities  Exchange
            Act of 1934,  as  amended  (the  "Exchange  Act")) (a  "Person")  of
            beneficial  ownership  (within the meaning of Rule 13d-3 promulgated
            under  the  Exchange  Act)  of 50% or more of  either  (1) the  then
            outstanding   shares  of  Common  Stock  of  the  Corporation   (the
            "Outstanding  Corporation  Common Stock") or (2) the combined voting
            power of the then outstanding  voting  securities of the Corporation
            entitled  to  vote  generally  in the  election  of  directors  (the
            "Outstanding  Corporation Voting  Securities");  provided,  however,
            that for purposes of this subsection (i), the following acquisitions
            shall  not  constitute  a Change  of  Control;  (1) any  acquisition
            directly  from  the   Corporation,   (2)  any   acquisition  by  the
            Corporation,  or (3) any acquisition by an employee benefit plan (or
            related  trust)  sponsored or maintained by the  Corporation  or any
            corporation controlled by the Corporation.

     (ii)   Approval  by the  shareholders  of  the  Corporation  of a  complete
            liquidation or dissolution of the  Corporation or the sale of all or
            substantially  all of the assets of the Corporation or the merger or
            consolidation of the Corporation with or into another corporation.

(c)  Change of  Control  Price.  For  purposes  of the Plan,  "Change of Control
     Price" means the higher of (i) the highest  reported  sales price,  regular
     way, of a share of Common Stock in any transaction reported on the New York
     Stock  Exchange  Composite  Tape or other  national  exchange on which such
     shares  are  listed or on NASDAQ  during  the  60-day  period  prior to and
     including  the date of a Change of Control or (ii) if the Change of Control
     is the result of a tender or exchange offer or a Corporate Transaction, the
     highest  price per share of Common  Stock paid in such  tender or  exchange
     offer or  Corporate  Transaction;  provided,  however,  that in the case of
     Incentive Stock Options and Stock Appreciation Rights relating to Incentive
     Stock  Options,  the Change of Control Price shall be in all cases the Fair
     Market Value of the Common Stock on the date such Incentive Stock Option or
     Stock Appreciation Right is exercised. To the extent that the consideration
     paid in any such  transaction  described  above  consists all or in part of
     securities or other non-cash consideration, the value of such securities or
     other noncash  consideration  shall be determined in the sole discretion of
     the Board.

                                                                              18
<PAGE>

                   SECTION 11. TERM, AMENDMENT AND TERMINATION

The Plan will  terminate 10 years after the effective  date of the Plan.  Awards
outstanding as of such date shall not be affected or impaired by the termination
of the Plan.

The Board may amend, alter or discontinue the Plan, but no amendment, alteration
or  discontinuation  shall be made  which  would  (i)  impair  the  rights of an
optionee  under a Stock  Option or a recipient  of a Stock  Appreciation  Right,
Restricted  Stock  Award,  Performance  Share  Award or  Performance  Unit Award
therefore granted without the optionee's or recipient's consent,  except such an
amendment  made to cause the Plan to qualify for the exemption  provided by Rule
16b-3, or (ii)  disqualify the Plan or any Award or transaction  thereunder from
the exemption  provided by Rule 16b-3.  In addition,  no such amendment shall be
made without the approval of the  Corporation's  shareholders to the extent such
approval is required by law, regulation or agreement.

The Committee may amend the terms of any Stock Option or other Award theretofore
granted, prospectively or retroactively,  but no such amendment shall impair the
rights of any holder without the holder's  consent except such an amendment made
to cause the Plan,  or Award,  transaction  or payment  made under the Plan,  to
qualify for the exemption provided by Rule 16b-3 and any such amendment shall be
subject to Section 2(e) hereof.

Subject to the above  provisions,  the Board shall have  authority  to amend the
Plan to take into account changes in law and tax and accounting rules as will as
other developments,  and to grant Awards which qualify for beneficial  treatment
under such rules with shareholder approval.

                       SECTION 12. UNFUNDED STATUS OF PLAN

It is presently  intended that the Plan shall  constitute an "unfunded" plan for
incentive and deferred compensation. The Committee may authorize the creation of
trusts or other  arrangements to meet the obligations  created under the Plan to
deliver  Common  Stock or make  payments;  provided  however,  that  unless  the
Committee  otherwise   determines,   the  existence  of  such  trusts  or  other
arrangements is consistent with the "unfunded" status of the Plan.

                         SECTION 13. GENERAL PROVISIONS

(a)  The  Committee  may require  each person  purchasing  or  receiving  shares
     pursuant  to an Award to  represent  to and agree with the  Corporation  in
     writing  that such  person is  acquiring  the shares  without a view to the
     distribution  thereof.  The  certificates  for such  shares may include any
     legend which the Committee deems appropriate to reflect any restrictions on
     transfer.

                                                                              19
<PAGE>

     Notwithstanding any other provision of the Plan or agreements made pursuant
     thereto,  the  Corporation  shall not be  required  to issue or deliver any
     certificate or certificates for shares of Common Stock under the Plan prior
     to fulfillment of all of the following conditions:

     (1)    Listing or  approval  for  listing  upon  notice of issuance of such
            shares  on  the  New  York  Stock  Exchange,  Inc.,  or  such  other
            securities  exchange as may at the time be the principal  market for
            the Common Stock;

     (2)    Any  registration  or  other  qualification  of such  shares  of the
            Corporation  under  any  state  or  federal  law or  regulation,  or
            maintaining in effect any such  registration or other  qualification
            which the  Committee  shall,  in its  absolute  discretion  upon the
            advice of counsel, deem necessary or advisable; and

     (3)    Obtaining  any other  consent,  approval or permit from any state or
            federal  governmental  agency  which  the  Committee  shall,  in its
            absolute discretion after receiving the advice of counsel, determine
            to be necessary or advisable.

(b)  Nothing  contained  in  the  Plan  shall  prevent  the  Corporation  or any
     Affiliate from adopting other or additional  compensation  arrangements for
     its employees and its Non-Employee Directors.

(c)  Neither  adoption of the Plan nor the grant or any Award  thereunder  shall
     confer upon any employee any right to  continued  employment,  nor shall it
     interfere in any way with the right of the  Corporation or any Affiliate to
     terminate the employment of any employee at any time.

(d)  No later than the date as of which an amount first  becomes  includible  in
     the gross income of the  participant  for federal  income tax purposes with
     respect  to any  Award  under the Plan,  the  participant  shall pay to the
     Corporation, or make arrangements satisfactory to the Corporation regarding
     the  payment of, any  federal,  state,  local or foreign  taxes of any kind
     required  by law  to be  withheld  with  respect  to  such  amount.  Unless
     otherwise  determined by the  Corporation,  withholding  obligations may be
     settled with Common Stock, including Common Stock that is part of the Award
     that gives rise to the  withholding  requirement.  The  obligations  of the
     Corporation  under  the Plan  shall be  conditioned  upon such  payment  or
     arrangements,  and the Corporation and its Affiliates  shall, to the extent
     permitted by law,  have the right to deduct any such taxes from any payment
     otherwise  due  to  the  participant.  The  Committee  may  establish  such
     procedures as it deems appropriate, including making irrevocable elections,
     for settlement of withholding obligations with Common Stock.

(e)  Reinvestment  of dividends in additional  Restricted  Stock or  Performance
     Shares at the time of any dividend  payment  shall only be  permissible  if
     sufficient  shares of Common Stock are  available  under Section 3 for such
     reinvestment  (taking into account then outstanding Stock Options and other
     Awards).

                                                                              20
<PAGE>

(f)  The Committee shall establish such procedures as it deems appropriate for a
     participant to designate a beneficiary  to whom any amounts  payable in the
     event of the  participant's  death are to paid or by whom any rights of the
     participant, after the participant's death, may be exercised.

(g)  In the case of a grant of an Award to any  employee of an  Affiliate of the
     Corporation,  the  Corporation  may, if the Committee so directs,  issue or
     transfer the shares of Common  Stock,  if any,  covered by the Award to the
     Affiliate, for such lawful consideration as the Committee may specify, upon
     the condition or understanding  that the Affiliate will transfer the shares
     of Common Stock to the employee in  accordance  with the terms of the Award
     specified by the Committee pursuant to the provisions of the Plan.

(h)  Notwithstanding  the foregoing,  if any right granted pursuant to this Plan
     would   make   a   Change   of   Control    transaction    ineligible   for
     pooling-of-interests accounting under APB No. 16 that but for the nature of
     such grant would otherwise be eligible for such accounting  treatment,  the
     Committee  shall  have the  ability  to  substitute  for any  cash  payable
     pursuant to such right  Common  Stock with a Fair Market Value equal to the
     cash that would otherwise be payable hereunder.

(i)  Notwithstanding  anything  in this  Plan to the  contrary,  no  transaction
     between a participant and the  Corporation  that requires as a condition of
     its  exemption  from  Section 16 of the Exchange Act approval in the manner
     set forth in paragraph  (d)(1) or (d)(2) of Rule 16b-3 shall be consummated
     until such approval is obtained;  but failure to obtain such approval shall
     not cause a  transaction  consummated  to be void or  voidable  without the
     consent of such  participant nor shall it disqualify the  transaction  from
     the benefit of any of available exemption from said Section 16.

(j)  Unless the Committee shall otherwise determine or any provision of the Plan
     shall otherwise  specifically  require, no delivery of cash and/or property
     shall be made to any "covered employee", as that term is defined in Section
     162(m)(3) of the Code, or any  transferee to whom the right of such covered
     employee to receive such cash and/or  property has been  transferred as the
     result of a transfer  permitted by the Plan, in any year to the extent that
     the value such cash and/or  property,  together with the value of all other
     cash and/or  property  delivered to such covered  employee or transferee in
     such year,  shall not be deductible by the  Corporation  as a result of the
     operation  of Section  162(m) of the Code.  Any cash  and/or  property  not
     deliverable  because of the  application of the previous  sentence shall be
     delivered  together  with  the  value of all  other  cash  and/or  property
     delivered  to such  covered  employee  or  transferee  in such year,  is so
     deductible,  until such cash and/or  property  shall have been delivered in
     full.  Such  undelivered  cash and/or property shall bear interest from the
     date on which it was first payable, but for the application of this Section
     (j),  until paid in full,  at a rate of interest per annum to be determined
     by the  Committee in  accordance  with any rules adopted under said Section
     162. For purposes of computing such interest, the Committee shall determine
     the value of such property,  based upon (i) its Fair Market Value (adjusted
     as the  Committee  shall see fit, but at least  quarterly)  if it is Common
     Stock or if its value is determinable with reference to the price of Common
     Stock or (ii) as the  Committee  shall  determine in all other cases.  This
     Section (j) shall cease to have effect upon

                                                                              21
<PAGE>

     the  occurrence  of a Change of Control  and the Plan shall  thereafter  be
     construed  as if this  Section (j) had never been part  thereof,  except in
     respect of the obligation of the  Corporation  to pay interest  pursuant to
     the provisions of this Section (j); without limiting the generality of this
     sentence, (i) all property deliverable as a result of such occurrence shall
     be delivered  when due as if this Section (j) were not part of the Plan and
     (ii) all property deliverable,  but for the provisions of this Section (j),
     shall  become  deliverable  upon such  Change  of  Control,  together  with
     interest accrued thereon.

(k)  The Plan and all Awards made and actions taken thereunder shall be governed
     by and  construed  in  accordance  with the laws of the  State of New York,
     without reference to principles of conflict of laws.

                                                                              22<PAGE>

           -----------------------
designated by a resolution adopted by the Board of Directors of the Company or a
duly authorized committee thereof as provided below; provided that (a) the
                                                     --------
holders of Indebtedness thereof do not have direct or indirect recourse against
the Company or any Restricted Subsidiary, and neither the Company nor any
Restricted Subsidiary otherwise has liability, for any payment obligations in
respect of such Indebtedness (including any undertaking, agreement or instrument
evidencing such Indebtedness), except, (i) in each case, to the extent that the
amount thereof constitutes a Restricted Payment permitted by the Indenture, (ii)
in the case of Non-Recourse Indebtedness, to the extent such recourse or
liability is for the matters discussed in the last sentence of the definition of
"Non-Recourse Indebtedness," or (iii) to the extent such Indebtedness is a
guarantee by such Subsidiary of Indebtedness of the Company or a Restricted
Subsidiary and (b) no holder of any Indebtedness of such Subsidiary shall have a
right to declare a default on such Indebtedness or cause the payment thereof to
be accelerated or payable prior to its stated maturity as a result of a default
on any Indebtedness of the Company or any Restricted Subsidiary.  Subject to the
foregoing, the Board of Directors of the Company or a duly authorized committee
thereof may designate any Subsidiary to be an Unrestricted Subsidiary; provided,
                                                                       --------

-------                                ------------------
all previous Investments by the Company and the Restricted Subsidiaries in such
Subsidiary will be deemed to be a Restricted Payment at the time of such
designation and will reduce the amount available for Restricted Payments under
Section 3.02 hereof, to the extent provided therein, (ii) the Company must be
permitted under Section 3.02 hereof to make the Restricted Payment deemed to
have been made pursuant to clause (i), and (iii) after giving effect to such
designation, no Default or Event of Default shall have occurred and be
continuing.  In accordance with the foregoing, and not in limitation thereof,
Investments made by any Person in any Subsidiary of such Person prior to such
Person's merger with the Company or any Restricted Subsidiary (but not in
contemplation or anticipation of such merger) shall not be counted as an
Investment by the Company or such Restricted Subsidiary if such Subsidiary of
such Person is designated as an Unrestricted Subsidiary.  The Board of Directors
of the Company or a duly authorized committee thereof may also redesignate an
Unrestricted Subsidiary to be a Restricted Subsidiary; provided, however, that
                                                       --------  -------

redesignation could then be incurred under Section 3.01 hereof and (ii)
immediately after giving effect to such redesignation and the incurrence of any
such additional Indebtedness, the Company and the Restricted Subsidiaries could
incur $1.00 of additional Indebtedness under Section 3.01(a) hereof.  Any such
designation or redesignation by the Board of Directors of the Company or a
committee thereof will be evidenced to the Trustee by the filing with the
Trustee of a certified copy of the resolution of the
<PAGE>

                                      -28-

Board of Directors of the Company or a committee thereof will be evidenced to
the Trustee by the filing with the Trustee of a certified copy of the resolution
of the Board of Directors of the Company or a committee thereof giving effect to
such designation or redesignation and an Officers' Certificate certifying that
such designation or redesignation complied with the foregoing conditions and
setting forth the underlying calculations of such Officers' Certificate. The
designation of any Person as an Unrestricted Subsidiary shall be deemed to
include a designation of all Subsidiaries of such Person as Unrestricted
Subsidiaries; provided, however, that the ownership of the general partnership
              --------  -------
interest (or a similar member's interest in a limited liability company) by an
Unrestricted Subsidiary shall not cause a Subsidiary of the Company of which
more than 95% of the equity interest is held by the Company or one or more
Restricted Subsidiaries to be deemed an Unrestricted Subsidiary.

          "Weighted Average Life to Maturity" means, when applied to any
           ---------------------------------
Indebtedness or portion thereof at any date, the number of years obtained by
dividing (i) the sum of the products obtained by multiplying (a) the amount of
each then remaining installment, sinking fund, serial maturity or other required
payment of principal, including, without limitation, payment at final maturity,
in respect thereof, by (b) the number of years (calculated to the nearest one-
twelfth) that will elapse between such date and the making of such payment by
(ii) the sum of all such payments described in clause (i)(a) above.

Section 3.01.  Limitations on Indebtedness.
               ---------------------------

          (a) Until the Notes are rated Investment Grade by both Rating Agencies
(after which time the following covenant will no longer be in effect), the
Company will not, and will not cause or permit any Restricted Subsidiary,
directly or indirectly, to, create, incur, assume, become liable for or
guarantee the payment of (collectively, an "incurrence") any Indebtedness
                                            ----------
(including Acquired Indebtedness) unless, after giving effect thereto and the
application of the proceeds therefrom, the Consolidated Fixed Charge Coverage
Ratio on the date thereof would be at least 2.0 to 1.0.

          (b) Notwithstanding the foregoing, the provisions of this Supplemental
Indenture will not prevent the incurrence of: (i) Permitted Indebtedness, (ii)
Refinancing Indebtedness, (iii) Non-Recourse Indebtedness, (iv) any Guarantee of
Indebtedness of the Company represented by the Notes and (v) any guarantee of
Indebtedness incurred under Credit Facilities in compliance with this Indenture.

          (c) For purposes of determining compliance with this covenant, in the
event that an item of Indebtedness may be incurred through the first paragraph
of this covenant or by meeting the criteria of one or more of the types of
Indebtedness described in the second paragraph of this covenant (or the
definitions of the terms used therein), the Company, in its sole discretion, (i)
may classify such item of Indebtedness under and comply with either
<PAGE>

                                      -29-

of such paragraphs (or any of such definitions), as applicable, (ii) may
classify and divide such item of Indebtedness into more than one of such
paragraphs (or definitions), as applicable, and (iii) may elect to comply with
such paragraphs (or definitions), as applicable, in any order.

          (d) The Company will not, and will not cause or permit any Guarantor
to, directly or indirectly, in any event incur any Indebtedness that purports to
be by its terms (or by the terms of any agreement governing such Indebtedness)
subordinated to any other Indebtedness of the Company or of such Guarantor, as
the case may be, unless such Indebtedness is also by its terms (or by the terms
of any agreement governing such Indebtedness) made expressly subordinated to the
Notes or the Guarantee of such Guarantor, as the case may be, to the same extent
and in the same manner as such Indebtedness is subordinated to such other
Indebtedness of the Company or such Guarantor, as the case may be.

Section 3.02.  Limitations on Restricted Payments.
               ----------------------------------

          (a) Until the Notes are rated Investment Grade by both Rating Agencies
(after which time the following covenant will no longer be in effect), the
Company will not, and will not cause or permit any Restricted Subsidiary to,
directly or indirectly, make any Restricted Payment unless:

          (i)    no Default or Event of Default shall have occurred and be
     continuing at the time of or immediately after giving effect to such
     Restricted Payment;

          (ii)   immediately after giving effect to such Restricted Payment,
     the Company could incur at least $1.00 of Indebtedness pursuant to Section
     3.01(a) hereof; and

          (iii)  immediately after giving effect to such Restricted Payment,
     the aggregate amount of all Restricted Payments (including the Fair Market
     Value of any non-cash Restricted Payment) declared or made after the Issue
     Date does not exceed the sum of (a) 50% of the Consolidated Net Income of
     the Company on a cumulative basis during the period (taken as one
     accounting period) from and including April 1, 1998, and ending on the last
     day of the Company's fiscal quarter immediately preceding the date of such
     Restricted Payment (or in the event such Consolidated Net Income shall be a
     deficit, minus 100% of such deficit), plus (b) 100% of the aggregate net
     cash proceeds of and the fair market value of Property received by the
     Company from (1) any capital contribution to the Company after June 9, 1997
     or any issue or sale after June 9, 1997 of Qualified Stock (other than to
     any Subsidiary of the Company) and (2) the issue or sale after June 9, 1997
     of any Indebtedness or other securities of the Company convertible into or
     exercisable for Qualified Stock of the Company that have been so converted
     or exercised, as the case may be, plus (c) $86.0 million, which is equal to
     the aggregate principal amount of the Company's 6 7/8% Convertible
     Subordinated Notes due 2002 that were converted into the Company's Common
     Equity prior to the
<PAGE>

                                      -30-

     Issue Date, plus (d) in the case of the disposition or repayment of any
     Investment constituting a Restricted Payment made after the June 9, 1997,
     an amount (to the extent not included in the calculation of the
     Consolidated Net Income referred to in (a)) equal to the lesser of (x) the
     return of capital with respect to such Investment (including by dividend,
     distribution or sale of Capital Stock) and (y) the amount of such
     Investment that was treated as a Restricted Payment, in either case, less
     the cost of the disposition or repayment of such Investment (to the extent
     not included in the calculation of the Consolidated Net Income referred to
     in (a)), plus (e) with respect to any Unrestricted Subsidiary that is
     redesignated as a Restricted Subsidiary after June 9, 1997 in accordance
     with the definition of Unrestricted Subsidiary (so long as the designation
     of such Subsidiary as an Unrestricted Subsidiary was treated as a
     Restricted Payment made after June 9, 1997 and only to the extent not
     included in the calculation of the Consolidated Net Income referred to in
     (a)), an amount equal to the lesser of (x) the proportionate interest of
     the Company or a Restricted Subsidiary in an amount equal to the excess of
     (I) the total assets of such Subsidiary, valued on an aggregate basis at
     the lesser of book value and Fair Market Value thereof, over (II) the total
     liabilities of such Subsidiary, determined in accordance with GAAP, and (y)
     the Designation Amount at the time of such Subsidiary's designation as an
     Unrestricted Subsidiary, plus (f) $50 million minus (g) the aggregate
     amount of all Restricted Payments (other than Restricted Payments referred
     to in clause (C) of the immediately succeeding paragraph) made after June
     9, 1997 through the Issue Date.

          (b) Clauses (ii) and (iii) of paragraph (a) will not prohibit:  (A)
the payment of any dividend within 60 days of its declaration if such dividend
could have been made on the date of its declaration without violation of the
provisions of this Indenture; (B) the repurchase, redemption or retirement of
any shares of Capital Stock of the Company in exchange for, or out of the net
proceeds of the substantially concurrent sale (other than to a Subsidiary of the
Company) of, other shares of Qualified Stock; and (C) the purchase, redemption
or other acquisition, cancellation or retirement for value of Capital Stock, or
options, warrants, equity appreciation rights or other rights to purchase or
acquire Capital Stock, of the Company or any Subsidiary held by officers or
employees or former officers or employees of the Company or any Subsidiary (or
their estates or beneficiaries under their estates) not to exceed $20 million in
the aggregate since the Issue Date; provided, however, that each Restricted
Payment described in clauses (A) and (B) of this sentence shall be taken into
account for purposes of computing the aggregate amount of all Restricted
Payments pursuant to clause (iii) of paragraph (a).

          (c) For purposes of determining the aggregate and permitted amounts of
Restricted Payments made, the amount of any guarantee of any Investment in any
Person that was initially treated as a Restricted Payment and which was
subsequently terminated or expired, net of any amounts paid by the Company or
any Restricted Subsidiary in respect of such guarantee, shall be deducted.
<PAGE>

                                      -31-

          (d) In determining the "fair market value of Property" for purposes of
clause (iii) of paragraph (a), Property other than cash, Cash Equivalents and
Marketable Securities shall be deemed to be equal in value to the "equity value"
of the Capital Stock or other securities issued in exchange therefor.  The
"equity value" of such Capital Stock or other securities shall be equal to (i)
the number of shares of Common Equity issued in the transaction (or issuable
upon conversion or exercise of the Capital Stock or other securities issued in
the transaction) multiplied by the closing sale price of the Common Equity on
its principal market on the date of the transaction (less, in the case of
Capital Stock or other securities which require the payment of consideration at
the time of conversion or exercise, the aggregate consideration payable
thereupon) or (ii) if the Common Equity is not then traded on the New York Stock
Exchange, American Stock Exchange or Nasdaq National Market, or if the Capital
Stock or other securities issued in the transaction do not consist of Common
Equity (or Capital Stock or other securities convertible into or exercisable for
Common Equity), the value of such Capital Stock or other securities as
determined by a nationally recognized investment banking firm retained by the
Board of Directors of the Company.

Section 3.03.  Limitations on Transactions with Affiliates.
               -------------------------------------------

          (a) Until the Notes are rated Investment Grade by both Rating Agencies
(after which time the following covenant will no longer be in effect), the
Company will not, and will not cause or permit any Restricted Subsidiary to,
make any loan, advance, guarantee or capital contribution to, or for the benefit
of, or sell, lease, transfer or otherwise dispose of any property or assets to,
or for the benefit of, or purchase or lease any property or assets from, or
enter into or amend any contract, agreement or understanding with, or for the
benefit of, any Affiliate of the Company or any Affiliate of any of the
Company's Subsidiaries or any holder of 10% or more of the Common Equity of the
Company (including any Affiliates of such holders), in a single transaction or
series of related transactions (each, an "Affiliate Transaction"), except for
                                          ---------------------
any Affiliate Transaction the terms of which are at least as favorable as the
terms which could be obtained by the Company or such Restricted Subsidiary, as
the case may be, in a comparable transaction made on an arm's length basis with
Persons who are not such a holder, an Affiliate of such a holder or an Affiliate
of the Company or any of the Company's Subsidiaries.

          (b) In addition, the Company will not, and will not cause or permit
any Restricted Subsidiary to, enter into an Affiliate Transaction unless (i)
with respect to any such Affiliate Transaction involving or having a value of
more than $10 million, the Company shall have (x) obtained the approval of a
majority of the Board of Directors of the Company and (y) either obtained the
approval of a majority of the Company's disinterested directors or obtained an
opinion of a qualified independent financial advisor to the effect that such
Affiliate Transaction is fair to the Company or such Restricted Subsidiary, as
the case may be, from a financial point of view and (ii) with respect to any
such Affiliate Transaction involving or having a value of more than $50 million,
the Company shall have (x) obtained the approval of
<PAGE>

                                      -32-

a majority of the Board of Directors of the Company and (y) delivered to the
Trustee an opinion of a qualified independent financial advisor to the effect
that such Affiliate Transaction is fair to the Company or such Restricted
Subsidiary, as the case may be, from a financial point of view.

          (c) Notwithstanding the foregoing, an Affiliate Transaction will not
include (i) any contract, agreement or understanding with, or for the benefit
of, or plan for the benefit of employees of the Company or its Subsidiaries
generally (in their capacities as such) that has been approved by the Board of
Directors of the Company, (ii) Capital Stock issuances to directors, officers
and employees of the Company or its Subsidiaries pursuant to plans approved by
the stockholders of the Company, (iii) any Restricted Payment otherwise
permitted under Section 3.02, (iv) any transaction between or among the Company
and one or more Restricted Subsidiaries or between or among Restricted
Subsidiaries (provided, however, no such transaction shall involve any other
              --------  -------
Affiliate of the Company (other than an Unrestricted Subsidiary to the extent
the applicable amount constitutes a Restricted Payment permitted by this
Indenture)) and (v) any transaction between one or more Restricted Subsidiaries
and one or more Unrestricted Subsidiaries where all of the payments to, or other
benefits conferred upon, such Unrestricted Subsidiaries are substantially
contemporaneously dividended, or otherwise distributed or transferred without
charge, to the Company or a Restricted Subsidiary.

Section 3.04.  Limitations on Dispositions of Assets.
               -------------------------------------

          Until the Notes are rated Investment Grade by both Rating Agencies
(after which time the following covenant will no longer be in effect), the
Company will not, and will not cause or permit any Restricted Subsidiary to,
make any Asset Disposition unless (x) the Company (or such Restricted
Subsidiary, as the case may be) receives consideration at the time of such Asset
Disposition at least equal to the Fair Market Value thereof, and (y) not less
than 70% of the consideration received by the Company (or such Restricted
Subsidiary, as the case may be) is in the form of cash, Cash Equivalents and
Marketable Securities.  The amount of any Indebtedness (other than any
Indebtedness subordinated to the Notes) of the Company or any Restricted
Subsidiary that is actually assumed by the transferee in such Asset Disposition
shall be deemed to be consideration required by clause (y) above for purposes of
determining the percentage of such consideration received by the Company or the
Restricted Subsidiaries.  The Net Cash Proceeds of an Asset Disposition shall,
within one year, at the Company's election, (a) be used by the Company or a
Restricted Subsidiary in the business of the construction and sale of homes
conducted by the Company and the Restricted Subsidiaries or any other business
of the Company or a Restricted Subsidiary existing at the time of such Asset
Disposition or (b) to the extent not so used, be applied to make a Net Cash
Proceeds Offer for the Notes and, if the Company or a Restricted Subsidiary
elects or is required to do so, repay, purchase or redeem any other
unsubordinated Indebtedness (on a pro rata basis if the amount available for
such repayment, purchase or redemption is less than the aggregate amount of (i)
the principal amount of the Notes tendered in such Net Cash Proceeds Offer and
<PAGE>

                                      -33-

(ii) the lesser of the principal amount, or accreted value, of such other
unsubordinated Indebtedness, plus, in each case accrued interest to the date of
repayment, purchase or redemption) at 100% of the principal amount or Accreted
Value thereof, as the case may be, plus accrued interest to the date of
repurchase or repayment.  Notwithstanding the foregoing, (A) the Company will
not be required to apply such Net Cash Proceeds to the repurchase of Notes in
accordance with clause (b) of the preceding sentence except to the extent that
such Net Cash Proceeds, together with the aggregate Net Cash Proceeds of prior
Asset Dispositions (other than those so used) which have not been applied in
accordance with this provision and as to which no prior Net Cash Proceeds Offer
shall have been made, exceed 5% of Consolidated Tangible Assets and (B) in
connection with any Asset Disposition, the Company and the Restricted
Subsidiaries will not be required to comply with the requirements of clause (y)
of the first sentence of this paragraph to the extent that the aggregate non-
cash consideration received in connection with such Asset Disposition, together
with the sum of all non-cash consideration received in connection with all prior
Asset Dispositions that has not yet been converted into cash, does not exceed 5%
of Consolidated Tangible Assets; provided, however, that when any non-cash
                                 --------  -------
consideration is converted into cash, such cash shall constitute Net Cash
Proceeds and be subject to the preceding sentence.

Section 3.05.  Limitations on Liens.
               --------------------

          The Company will not, and will not cause or permit any Restricted
Subsidiary to, create, incur, assume or suffer to exist any Liens, other than
Permitted Liens, on any of its Property, or on any shares of Capital Stock or
Indebtedness of any Restricted Subsidiary, unless contemporaneously therewith or
prior thereto all payments due under this Indenture and the Notes are secured on
an equal and ratable basis with the obligation or liability so secured until
such time as such obligation or liability is no longer secured by a Lien.

Section 3.06.  Limitations on Restrictions Affecting Restricted Subsidiaries.
               -------------------------------------------------------------

          The Company will not, and will not cause or permit any Restricted
Subsidiary to, create, assume or otherwise cause or suffer to exist or become
effective any consensual encumbrance or restriction (other than encumbrances or
restrictions imposed by law or by judicial or regulatory action or by provisions
of leases and other agreements that restrict the assignability thereof) on the
ability of any Restricted Subsidiary to (i) pay dividends or make any other
distributions on its Capital Stock or any other interest or participation in, or
measured by, its profits, owned by the Company or any other Restricted
Subsidiary, or pay interest on or principal of any Indebtedness owed to the
Company or any other Restricted Subsidiary, (ii) make loans or advances to the
Company or any other Restricted Subsidiary, or (iii) transfer any of its
properties or assets to the Company or any other Restricted Subsidiary, except
for (a) encumbrances or restrictions existing under or by reason of applicable
law, (b) covenants or restrictions contained in Indebtedness in effect on the
date of this Indenture as such covenants or restrictions are in effect on such
date, (c) any restrictions or encum-
<PAGE>

                                      -34-

brances arising under Acquired Indebtedness; provided, that such encumbrance or
                                             --------
restriction applies only to either the assets that were subject to the
restriction or encumbrance at the time of the acquisition or the obligor on such
Indebtedness and its Subsidiaries, (d) any restrictions or encumbrances arising
in connection with Refinancing Indebtedness; provided, however, that any
                                             --------  -------
restrictions and encumbrances of the type described in this clause (d) that
arise under such Refinancing Indebtedness shall not be materially more
restrictive than those under the agreement creating or evidencing the
Indebtedness being refunded, refinanced, replaced or extended, (e) any Permitted
Lien, or any other agreement restricting the sale or other disposition of
property, securing Indebtedness permitted by this Indenture if such Permitted
Lien or agreement does not expressly restrict the ability of a Subsidiary of the
Company to pay dividends or make or repay loans or advances prior to default
thereunder, (f) reasonable and customary borrowing base covenants set forth in
agreements evidencing Indebtedness otherwise permitted by this Indenture, (g)
customary provisions restricting subletting or assignment of any lease governing
a leasehold interest of the Company or any Restricted Subsidiary, and (h) any
restriction with respect to a Restricted Subsidiary imposed pursuant to an
agreement entered into for the sale or disposition of all or substantially all
of the Capital Stock or assets of such Restricted Subsidiary pending the closing
of such sale or disposition.

Section 3.07.  Limitations on Mergers, Consolidations and Sales of Assets.
               ----------------------------------------------------------

          Neither the Company nor any Guarantor will consolidate or merge with
or into, or sell, lease, convey or otherwise dispose of all or substantially all
of its assets (including, without limitation, by way of liquidation or
dissolution), or assign any of its obligations under the Notes, the Guarantees
or this Indenture (as an entirety or substantially in one transaction or in a
series of related transactions), to any Person (in each case other than in a
transaction in which the Company or a Restricted Subsidiary is the survivor of a
consolidation or merger, or the transferee in a sale, lease, conveyance or other
disposition) unless:  (i) the Person formed by or surviving such consolidation
or merger (if other than the Company or the Guarantor, as the case may be), or
to which such sale, lease, conveyance or other disposition or assignment will be
made (collectively, the "Successor"), is a corporation or other legal entity
                         ---------
organized and existing under the laws of the United States or any state thereof
or the District of Columbia, and the Successor assumes by supplemental indenture
in a form reasonably satisfactory to the Trustee all of the obligations of the
Company or the Guarantor, as the case may be, under the Notes or a Guarantee, as
the case may be, and the Indenture, (ii) immediately after giving effect to such
transaction, no Default or Event of Default has occurred and is continuing,
(iii) immediately after giving effect to such transaction and the use of any net
proceeds therefrom, on a pro forma basis, the Consolidated Net Worth of the
                         --- -----
Company or the Successor (in the case of a transaction involving the Company),
as the case may be, would be at least equal to the Consolidated Net Worth of the
Company immediately prior to such transaction (exclusive of any adjustments to

immediately after giving effect to such transaction, the Company could incur at
least $1.00 of Indebtedness pursuant to Section 3.01(a) hereof. The foregoing
provisions shall not apply to (i) a transaction involving the sale or
disposition of Capital Stock of a Guarantor, or the consolidation or merger of a
Guarantor, or the sale, lease, conveyance or other disposition of all or
substantially all of the assets of a Guarantor, that in any such case results in

Section 3.08.  Reports to Holders of Notes.
               ---------------------------

          The Company will file with the Commission the annual reports and the
information, documents and other reports required to be filed pursuant to
Section 13 or 15(d) of the Exchange Act.  The Company will file with the Trustee
and mail to each Holder of record of Notes such reports, information and
documents within 15 days after it files them with the Commission.  In the event
that the Company is no longer subject to these periodic requirements of the
Exchange Act, it will nonetheless continue to file reports with the Commission
and the Trustee and mail such reports to each holder of Notes as if it were
subject to such reporting requirements.  Regardless of whether the Company is
required to furnish such reports to its stockholders pursuant to the Exchange
Act, the Company will cause its consolidated financial statements and a
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" written report, similar to those that would have been required to
appear in annual or quarterly reports, to be delivered to Holders of Notes.

                           REDEMPTION AND CONVERSIONS

Section 4.01.  Optional Redemption by the Company.
               ----------------------------------

          (a) Right to Redeem; Notice to Trustee.  The Company, at its option,
              ----------------------------------
may redeem the Notes in accordance with the provisions of paragraphs 6 and 8 of
the Notes.  If the Company elects to redeem Notes pursuant to paragraph 6 of the
Notes, it shall notify the Trustee in writing of the Redemption Date, the
Principal Amount at Final Maturity of Notes to be redeemed, the Redemption Price
and the amount of contingent interest, if any, payable on the Redemption Date.
The Company shall give the notice to the Trustee provided for in this Section
4.01(a) at least 30 days but not more than 60 days before the Redemption Date.

          (b) Selection of Notes to be Redeemed.  If any Note selected for
              ---------------------------------
partial redemption is thereafter surrendered for conversion in part before
termination of the conversion right with respect to the portion of the Note so
selected, the converted portion of such Note shall be deemed (so far as may be),
solely for purposes of determining the aggregate Principal Amount at Final
Maturity of Notes to be redeemed by the Company, to be the portion selected
<PAGE>

                                      -36-

for redemption. Notes which have been converted during a selection of Notes to
be redeemed may be treated by the Trustee as outstanding for the purpose of such
selection. Nothing in this Section 4.01(b) shall affect the right of any Holder
to convert any Note pursuant to Sections 4.05, 4.06 and 4.07 before the
termination of the conversion right with respect thereto.

          (c) Notice of Redemption.  At least 30 days but not more than 60 days
              --------------------
before a Redemption Date, the Company shall mail or cause to be mailed a notice
of redemption by first-class mail to the Trustee and to each Holder of Notes to
be redeemed at such Holder's address as it appears on the Note register.

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

          (i)     the Redemption Date;

          (ii)    the Redemption Price and, to the extent known at the time of
     such notice, the amount of contingent interest, if any, payable on the
     Redemption Date;

          (iii)   the then current Conversion Rate;

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

          (v)     that Notes called for redemption must be presented and
     surrendered to the Paying Agent to collect the Redemption Price and
     contingent interest, if any;

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

          (vii)   that Holders who wish to convert Notes must comply with the
     procedures in paragraph 10 of the Notes;

          (viii)  that, unless the Company defaults in making payment of such
     Redemption Price and contingent interest, if any, Accreted Value and
     interest (including contingent interest), if any, on the Notes called for
     redemption will cease to accrue on and after the Redemption Date and the
     only remaining right of the Holder will be to receive payment of the
     Redemption Price upon presentation and surrender to the Paying Agent of the
     Notes;

          (ix)    if fewer than all the outstanding Notes are to be redeemed,
     the certificate number and Principal Amounts at Final Maturity of the
     particular Notes to be redeemed; and

          (x)     the CUSIP number or numbers for the Notes called for
     redemption.
<PAGE>

                                      -37-

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense.

          (d) Effect of Notice of Redemption.  Once notice of redemption is
              ------------------------------
mailed, Notes called for redemption become due and payable on the Redemption
Date and at the Redemption Price (together with accrued and unpaid contingent
interest, if any) stated in the notice, except for Notes that are converted in
accordance with the provisions of Sections 4.05, 4.06 and 4.07.  Upon
presentation and surrender to the Paying Agent, Notes called for redemption
shall be paid at the Redemption Price (together with accrued contingent
interest, if any).

          (e) Sinking Fund.  There shall be no sinking fund provided for the
              ------------
Notes.

          (f) Deposit of Redemption Price.  On or before 11:00 a.m. (New York
              ---------------------------
City time) on the Redemption Date, the Company shall deposit with the Trustee or
with the Paying Agent (or, if the Company or an Affiliate of the Company is
acting as the Paying Agent, shall segregate and hold in trust) an amount of
money sufficient to pay the aggregate Redemption Price of, and any accrued and
unpaid contingent interest with respect to, all the Notes to be redeemed on that
date other than the Notes or portions thereof called for redemption which on or
prior thereto have been delivered by the Company to the Trustee for cancellation
or have been converted.  The Trustee and the Paying Agent shall, as promptly as
practicable, return to the Company any money not required for that purpose
because of conversion of the Notes in accordance with the provisions of Sections
4.05, 4.06, 4.07.  If such money is then held by the Company or a Subsidiary in
trust and is not required for such purpose, it shall be discharged from such
trust.

Section 4.02.  Purchase at Option of the Holder Upon a Fundamental Change.
               ----------------------------------------------------------

          (a) If a Fundamental Change shall occur at any time prior to May 11,
2003, each Holder of Notes shall have the right, at such Holder's option, to
require the Company to purchase such Holder's Notes on the date (the

"Fundamental Change Purchase Date") (or if such date is not a Business Day, the
---------------------------------
next succeeding Business Day) that is 95 days after the date of the Fundamental
Change.  The Notes shall be purchased in integral multiples of $1,000 of
Principal Amount at Final Maturity.  The Company shall purchase such Notes for
Cash at a price (the "Fundamental Change Purchase Price") equal to the Issue
                      ---------------------------------
Price plus Accreted Value to the Fundamental Change Purchase Date or for shares
of Common Stock as set forth in Section 4.03.  No Notes may be purchased at the
option of the Holders due to a Fundamental Change if there has occurred and is
continuing an Event of Default (other than a default in the payment of the
Fundamental Change Purchase Price with respect to such Notes).

          (b) The Company, or at its request (which must be received by the
Trustee at least three Business Days (or such lesser period as agreed to by the
Trustee) prior to the date the Trustee is requested to give such notice as
described below) the Trustee in the name
<PAGE>

                                      -38-

of and at the expense of the Company, shall mail to all Holders of record of the
Notes a notice (a "Company Fundamental Change Notice") of the occurrence of a
                   ---------------------------------
Fundamental Change and of the repurchase right arising as a result thereof,
including the information required by Section 4.03(f) hereof, on or before the
30th day after the occurrence of such Fundamental Change. The Company shall
promptly furnish to the Trustee a copy of such notice.

          (c) For a Note to be so repurchased at the option of the Holder, the
Paying Agent must receive such Note with the form entitled "Fundamental Change
Purchase Notice" on the reverse thereof duly completed, together with such Note
duly endorsed for transfer, on or before the 60th day after the Company
Fundamental Change Notice is delivered.  All questions as to the validity,
eligibility (including time of receipt) and acceptance of any Note for
redemption shall be determined by the Company, whose determination shall be
final and binding.

Section 4.03.  Purchase of Notes at the Option of the Holder; Payment of
               Purchase Price or Fundamental Change Purchase Price in Stock.
               ------------------------------------------------------------

          (a) Purchase of Notes at the Option of the Holder.  On each of May 11,
              ---------------------------------------------
2003, May 11, 2008 and May 11, 2013 (each, a "Purchase Date"), at the purchase
                                              -------------
price specified in paragraph 7 of the Notes (each, a "Purchase Price"), a Holder
                                                      --------------
of Notes shall have the option to require the Company to purchase any
outstanding Notes, upon:

          (i)    delivery to the Paying Agent by the Holder of a written notice
     of purchase (a "Purchase Notice") at any time from the opening of business
                     ---------------
     on the date that is 30 Business Days prior to a Purchase Date until the
     close of business on such Purchase Date, stating:

                 (A) the certificate numbers of the Notes which the Holder shall
          deliver to be purchased;

                 (B) the portion of the Principal Amount at Final Maturity of
          the Notes which the Holder shall deliver to be purchased, which
          portion must be $1,000 in Principal Amount at Final Maturity or a
          multiple thereof;

                 (C) that such Notes shall be purchased as of the Purchase Date
          pursuant to the terms and conditions specified in paragraph 7 of the
          Notes and in this Supplemental Indenture; and

                 (D) if the Company elects, pursuant to a Company Notice, to pay
          the Purchase Price to be paid as of such Purchase Date, in whole or in
          part, in Common Stock but such portion of the Purchase Price shall
          ultimately be payable to such Holder in Cash because any of the
          conditions to the payment of the Purchase Price in Common Stock are
          not satisfied prior to or on the Pur-
<PAGE>

                                      -39-

          chase Date, as set forth in Section 4.03(d), whether such Holder
          elects (x) to withdraw such Purchase Notice as to some or all of the
          Notes to which such Purchase Notice relates (stating the Principal
          Amount at Final Maturity and certificate numbers of the Notes as to
          which such withdrawal shall relate), or (y) to receive Cash in respect
          of the entire Purchase Price for all Notes (or portions thereof) to
          which such Purchase Notice relates; and

          (ii)   delivery or book-entry transfer of such Note to the Paying
     Agent prior to, on or after the Purchase Date (together with all necessary
     endorsements) at the offices of the Paying Agent, such delivery or transfer
     being a condition to receipt by the Holder of the Purchase Price therefor;

     provided, however, that such Purchase Price shall be so paid pursuant to
     --------  -------
     this Section 4.03 only if the Note so delivered or transferred to the
     Paying Agent shall conform in all respects to the description thereof in
     the related Purchase Notice.

          (b) Procedures.  If a Holder, in such Holder's Purchase Notice or
              ----------
Fundamental Change Purchase Notice (and in any written notice of withdrawal of a
portion of a Holder's Notes previously submitted for purchase pursuant to a
Purchase Notice or Fundamental Change Purchase Notice, the portion that remains
subject to the Purchase Notice or Fundamental Change Purchase Notice), fails to
indicate such Holder's choice with respect to the election regarding a
conditional withdrawal pursuant to the terms of clause (D) of Section 4.03(a)(i)
or the penultimate paragraph of the Fundamental Change Purchase Notice such
Holder shall be deemed to have elected to receive Cash in respect of all Notes
subject to such Purchase Notice or Fundamental Change Purchase Notice in the
circumstances set forth in such clause (D) and penultimate paragraph.

          The Company shall purchase from the Holder thereof, pursuant to this
Section 4.03, a portion of a Note if the Principal Amount at Final Maturity of
such portion is $1,000 or a multiple of $1,000 if so requested by the Holder.
Provisions of this Supplemental Indenture that apply to the purchase of all of a
Note also apply to the purchase of such portion of such Note.

          Any purchase by the Company contemplated pursuant to the provisions of
Section 4.02 or this Section 4.03 shall be consummated by the delivery of the
consideration to be received by the Holder (together with accrued and unpaid
contingent interest, if any) promptly following the later of the Purchase Date
and the time of delivery or book-entry transfer of the Note.

          Notwithstanding anything herein to the contrary, any Holder delivering
to the Paying Agent the Purchase Notice or Fundamental Change Purchase Notice
contemplated by Section 4.02 or this Section 4.03(a) shall have the right at any
time prior to the close of business on the Purchase Date or Fundamental Change
Purchase Date to withdraw such Purchase

                                      -40-

Notice or Fundamental Change Purchase Notice (in whole or in part) by delivery
of a written notice of withdrawal to the Paying Agent in accordance with Section
4.04(a).

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

          (c) Company's Right to Elect Manner of Payment of Purchase Price.  The
              ------------------------------------------------------------
Company may elect with respect to any Purchase Date or Fundamental Change
Purchase Date to pay the Purchase Price or Fundamental Change Purchase Price in
respect of the Notes to be purchased pursuant to Section 4.02 or Section 4.03(a)
as of such Purchase Date or Fundamental Change Purchase Date, in U.S. legal
tender ("Cash") or Common Stock, or in any combination of Cash and Common Stock,
         ----
subject to the conditions set forth in Sections 4.03(d) and (e); provided,
                                                                 --------
however, that any Purchase Price paid on May 11, 2003 pursuant to Section
-------
4.03(a) must be paid fully in Cash.  The Company shall designate, in the Company
Notice delivered pursuant to Section 4.03(f), whether the Company shall purchase
the Notes for Cash or Common Stock, or, if a combination thereof, the
percentages of the Purchase Price or Fundamental Change Purchase Price of Notes
in respect of which it shall pay in Cash and/or Common Stock; provided that the
Company shall pay Cash for fractional interests in Common Stock.  For purposes
of determining the existence of potential fractional interests, all Notes
subject to purchase by the Company held by a Holder shall be considered together
(no matter how many separate certificates are to be presented).  Each Holder
whose Notes are purchased pursuant to this Section 4.03 shall receive the same
percentage of Cash and/or Common Stock in payment of the Purchase Price or
Fundamental Change Purchase Price for such Notes, except (i) as provided in
Section 4.03(e) with regard to the payment of Cash in lieu of fractional
interests in Common Stock and (ii) in the event that the Company is unable to
purchase the Notes of a Holder or Holders for Common Stock because any necessary
qualifications or registrations of the Common Stock under applicable federal or
state securities laws cannot be obtained, the Company may purchase the Notes of
such Holder or Holders for Cash.  Once the Company has given its Company Notice
to Holders, the Company may not change its election with respect to the
consideration (or components or percentages of components thereof) to be paid
except pursuant to this Section 4.03(c) or Section 4.03(e).

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

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

          (ii)   the information required by Section 4.03(f);

          (iii)  if the Company elects to pay the Purchase Price or
     Fundamental Change Purchase Price, or a specified percentage thereof, in
     Common Stock, that the
<PAGE>

                                      -41-

     conditions to such manner of payment set forth in Section 4.03(e) have been
     or shall be complied with; and

          (iv)   whether the Company desires the Trustee to give the Company
     Notice required by Section 4.03(f).

          (d) Purchase with Cash.  At the option of the Company, the Purchase
              ------------------
Price or Fundamental Change Purchase Price of Notes in respect of which a
Purchase Notice or Fundamental Change Purchase Notice pursuant to Section 4.02
or Section 4.03(a) has been given, or a specified percentage thereof, may be
paid by the Company with Cash equal to the aggregate Purchase Price or
Fundamental Change Repurchase Price, or such specified percentage thereof, as
the case may be, of such Notes.

          (e) Payment by Issuance of Common Stock.  At the option of the
              -----------------------------------
Company, subject to Section 4.03(c), the Purchase Price of Notes in respect of
which a Purchase Notice pursuant to Section 4.03(a) or Fundamental Change
Purchase Notice has been given, or a specified percentage thereof, may be paid
by the Company by the issuance of a number of shares of Common Stock equal to
the quotient obtained by dividing (x) the amount of Cash to which the Holders
would have been entitled had the Company elected to pay all or such specified
percentage, as the case may be, of the Purchase Price or Fundamental Change
Purchase Price of such Notes in Cash by (y) 0.95 times the Market Price of a
share of Common Stock, subject to the next succeeding paragraph.

          The Company shall not issue a fractional share of Common Stock in
payment of the Purchase Price or Fundamental Change Purchase Price.  Instead the
Company shall pay Cash for the current market value of the fractional share.
The current market value of a fraction of a share shall be determined by
multiplying the Market Price by such fraction and rounding the product to the
nearest whole cent.  It is understood that if a Holder elects to have more than
one Note purchased, the number of shares of Common Stock shall be based on the
aggregate amount of Notes to be purchased.

          The Company's right to exercise its election to purchase the Notes
pursuant to Section 4.02 or Section 4.03 through the issuance of shares of
Common Stock shall be conditioned upon:

          (i)    the Company having given timely written notice in accordance
     with Section 4.03(f) of its election to purchase all or a specified
     percentage of the Notes with Common Stock as provided herein;

          (ii)   (A)(1) the registration of the shares of Common Stock to be
     issued in respect of the payment of the specified percentage of the
     Purchase Price or Fundamental Change Purchase Price under the Securities
     Act of 1933 or (2) the issuance of the shares of Common Stock in an action
     which is exempt from the registration re-
<PAGE>

                                      -42-

     quirements of the Securities Act of 1933 and which will not result in such
     shares of Common Stock being deemed" restricted securities" under the
     Securities Act of 1933 or otherwise and (B) the registration of the shares
     of Common Stock under the Securities Exchange Act of 1934;

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

          (iv)   the receipt by the Trustee of an Officers' Certificate and an
     Opinion of Counsel each stating that (A) the terms of the issuance of the
     Common Stock are in conformity with this Supplemental Indenture and (B) the
     shares of Common Stock to be issued by the Company in payment of the
     specified percentage of the Purchase Price or Fundamental Change Purchase
     Price in respect of Notes have been duly authorized and, when issued and
     delivered pursuant to the terms of this Supplemental Indenture in payment
     of the specified percentage of the Purchase Price or Fundamental Change
     Purchase Price in respect of Notes, shall be validly issued, fully paid and
     nonassessable, and, to the best of such counsel's knowledge, free from
     preemptive rights, and in the case of such Officers' Certificate, stating
     that conditions (i), (ii) and (iii) above have been satisfied and, in the
     case of such Opinion of Counsel, stating that conditions (ii) and (iii)
     above have been satisfied.

          Such Officers' Certificate shall also set forth the number of shares
of Common Stock to be issued for each $1,000 Principal Amount at Final Maturity
of Notes and the Sale Price of a share of Common Stock on each Trading Day
during the period during which the Market Price is calculated and ending on the
Purchase Date or Fundamental Change Purchase Date.  The Company may elect to pay
the Purchase Price or Fundamental Change Purchase Price (or any portion thereof)
in Common Stock only if the information necessary to calculate the Market Price
is reported in a daily newspaper of national circulation.  If any of the
conditions set forth in this Section 4.03(e) are not satisfied with respect to a
Holder or Holders prior to or on the Purchase Date or Fundamental Change
Repurchase Date and the Company elected to purchase the Notes to be purchased as
of such Purchase Date or Fundamental Change Repurchase Date pursuant to Section
4.02 or this Section 4.03 through the issuance of shares of Common Stock, the
Company shall pay the entire Purchase Price or Fundamental Change Purchase Price
in respect of such Notes of such Holder or Holders in Cash.

          Upon determination of the actual number of shares of Common Stock
which the Holder of each $1,000 Principal Amount at Final Maturity of the Notes
shall receive, the Company shall publish such determination in a daily newspaper
of national circulation.

          (f) Notice of Election.  The Company's notices of election to purchase
              ------------------
with Cash or Common Stock, or any combination thereof (each a "Company Notice"),
                                                               --------------
shall be sent to the Holders (and to beneficial owners as required by applicable
law) at their ad-
<PAGE>

                                      -43-

dresses shown in the Note register maintained by the Registrar, and delivered to
the Trustee, not less than 30 Business Days prior to the Purchase Date (the
"Company Notice Date") or on or before the 30th day after the occurrence of the
 -------------------
Fundamental Change, as the case may be. Such Company Notices shall state the
manner of payment elected and shall contain the following information.

          In the event the Company has elected to pay a Purchase Price or
Fundamental Change Purchase Price (or a specified percentage thereof) with
Common Stock, the Company Notice shall:

          (i)    state that each Holder shall receive Common Stock in respect of
     the specified percentage of the Purchase Price or Fundamental Change
     Purchase Price of the Notes held by such Holder (except any Cash amount to
     be paid in lieu of fractional share);

          (ii)   state that the total number of shares of Common Stock to be
     issued to Holders will be equal to the quotient obtained by dividing (x)
     the amount of cash to which the Holders would have been entitled had the
     Company elected to pay all or such specified percentage, as the case may
     be, of the Purchase Price or Fundamental Change Purchase Price of such
     Notes in cash by (y) 0.95 times the Market Price of a share of Common
     Stock;

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

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

          In any case, each Company Notice shall include a form of Purchase
Notice or Fundamental Change Repurchase Notice to be completed by a Holder and
shall state:

          (i)    the Purchase Price, Conversion Rate and, to the extent known at
     the time of such notice, the amount of contingent interest, if any, that
     will be payable with respect to the Notes on the Purchase Date;

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

          (iii)  that Notes as to which a Purchase Notice or Fundamental Change
     Purchase Notice has been given may be converted only if the applicable

     Supplemental Indenture;
<PAGE>

                                      -44-

          (iv)   that Notes must be surrendered to the Paying Agent to collect
     payment of the Purchase Price or Fundamental Change Purchase Price and
     contingent interest, if any;

          (v)    that the Purchase Price or Fundamental Change Purchase Price
     for any Note as to which a Purchase Notice has been given and not
     withdrawn, together with any accrued contingent interest payable with
     respect thereto, shall be paid promptly following the later of the Purchase
     Date or Fundamental Change Purchase Date and the time of surrender of such
     Note as described in (iv);

          (vi)   the procedures the Holder must follow under Section 4.02 and
     Section 4.03;

          (vii)  briefly, the conversion rights of the Notes;

          (viii) that, unless the Company defaults in making payment of such
     Purchase Price or Fundamental Change Purchase Price and contingent
     interest, if any, Accreted Value and interest (including contingent
     interest), if any, on Notes covered by any Purchase Notice or Fundamental
     Change Purchase Notice (or interest, if the Notes have been converted into
     semi-annual cash pay notes pursuant to Section 4.08 of this Supplemental
     Indenture), if any, will cease to accrue on and after the Purchase Date;

          (ix)   the CUSIP or ISIN number of the Notes; and

          (x)    the procedures for withdrawing a Purchase Notice or Fundamental
     Change Purchase Notice (including, without limitation, for a conditional
     withdrawal pursuant to the terms of Section 4.03(a)(i)(D) or the
     penultimate paragraph of the Fundamental Change Purchase Notice).

          At the Company's request and at the Company's expense, the Trustee
shall give the Company Notice in the Company's name; provided, however, that, in
                                                     --------  -------
all cases, the text of the Company Notice shall be prepared by the Company.

          (g) Covenants of the Company.  All shares of Common Stock delivered
              ------------------------
upon conversion or purchase of the Notes shall be newly issued shares or
treasury shares, shall be fully paid and nonassessable and shall be free from
preemptive rights and free of any lien or adverse claim.

          The Company shall cause to have listed or quoted all such shares of
Common Stock on each United States national securities exchange or over-the-
counter or other domestic market on which the Common Stock is then listed or
quoted.

          (h) Procedure Upon Purchase.  On or before 11:00 a.m. (New York City
              -----------------------
time) on the Purchase Date or Fundamental Change Purchase Date, the Company
shall deposit with the Paying Agent Cash (in respect of a Cash purchase under
Section 4.03(d) or for fractional interests or contingent interests, as
applicable), or shares of Common Stock, or a combination thereof, as applicable,
sufficient to pay the aggregate Purchase Price or Fundamental Change Purchase
Price of, and any accrued and unpaid interest with respect to, the Notes to be
purchased pursuant to this Section 4.03.  Payment of the Purchase Price or
Fundamental Change Purchase Price for such Note shall be made as soon as
practicable following the later of the Purchase Date or Fundamental Change
Purchase Date or the time of book-entry transfer or delivery of such Note.  If
the Company is delivering Common Stock, the Company shall deliver to each Holder
entitled to receive Common Stock, through the Paying Agent, a certificate for
the number of full shares of Common Stock, as applicable, issuable in payment of
such Purchase Price or Fundamental Change Purchase Price and Cash in lieu of any
fractional interests.  The Person in whose name the certificate for Common Stock
is registered shall be treated as a holder of record following the Purchase Date
or Fundamental Change Purchase Date.  Subject to Section 4.03(e), no payment or
adjustment shall be made for dividends on the Common Stock the record date for
which occurred on or prior to the Purchase Date or Fundamental Change Purchase
Date.  If the Paying Agent holds, in accordance with the terms of the Indenture,
money or securities sufficient to pay the Purchase Price or Fundamental Change
Purchase Price of such Note on the Business Day following the Purchase Date or
Fundamental Change Purchase Date, then, on and after such date, such Note shall
cease to be outstanding and Original Issue Discount on such Note shall cease to
accrue, whether or not book-entry transfer of such Note is made or such Note is
delivered to the Paying Agent, and all other rights of the Holder shall
terminate (other than the right to receive the Purchase Price or Fundamental
Change Purchase Price upon delivery or transfer of the Note).

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

Section 4.04.  Further Conditions for Purchase at the Option of Holders Upon a
               Fundamental Change and Purchase of Notes at the Option of the
               Holder.

          (a) Effect of Purchase Notice or Fundamental Change Purchase Notice.
              ---------------------------------------------------------------
Upon receipt by the Company of the Purchase Notice or Fundamental Change
Purchase No-
<PAGE>

                                      -46-

tice specified in Section 4.03(a) or Section 4.02(c), as applicable, the Holder
of the Note in respect of which such Purchase Notice or Fundamental Change
Purchase Notice, as the case may be, was given shall (unless such Purchase
Notice or Fundamental Change Purchase Notice is withdrawn as specified in the
following two paragraphs) thereafter be entitled to receive solely the Purchase
Price or Fundamental Change Purchase Price, as the case may be, and any accrued
and unpaid contingent interest, if any, with respect to such Note. Such Purchase
Price or Fundamental Change Purchase Price and contingent interest, if any,
shall be paid to such Holder promptly following the later of (x) the Purchase
Date or the Fundamental Change Purchase Date, as the case may be, with respect
to such Note (provided the conditions in Section 4.03(a) or Section 4.02(c), as
applicable, have been satisfied) and (y) the time of delivery or book-entry
transfer of such Note to the Paying Agent by the Holder thereof in the manner
required by Section 4.03(a) or Section 4.02(c), as applicable. Notes in respect
of which a Purchase Notice or Fundamental Change Purchase Notice, as the case
may be, has been given by the Holder thereof may not be converted for shares of
Common Stock on or after the date of the delivery of such Purchase Notice (or
Fundamental Change Purchase Notice, as the case may be), unless such Purchase
Notice (or Fundamental Change Purchase Notice, as the case may be) has first
been validly withdrawn as specified in the following two paragraphs.

          A Purchase Notice or Fundamental Change Purchase Notice, as the case
may be, may be withdrawn by means of a written notice of withdrawal delivered to
the office of the Paying Agent at any time prior to the close of business on the
Purchase Date or the Fundamental Change Purchase Date, as the case may be, to
which it relates specifying:

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

          (b)  the Principal Amount at Final Maturity of the Notes with respect
     to which such notice of withdrawal is being submitted; and

          (c)  the Principal Amount at Final Maturity, if any, of the Notes
     which remain subject to the original Purchase Notice or Company Fundamental
     Change Notice, as the case may be, and which has been or shall be delivered
     for purchase by the Company.

          A written notice of withdrawal of a Purchase Notice or Fundamental
Change Purchase Notice may be in the form of (i) a conditional withdrawal
contained in a Purchase Notice pursuant to the terms of Section 4.03(a)(i)(D) or
a Fundamental Change Purchase Notice pursuant to the penultimate paragraph
thereof or (ii) a conditional withdrawal containing the information set forth in
the preceding paragraph and contained in a written notice of withdrawal
delivered to the Paying Agent as set forth in the preceding paragraph.

          There shall be no purchase of any Notes pursuant to Section 4.02 or
Section 4.03 (other than through the issuance of Common Stock in payment of the
Purchase Price
<PAGE>

                                      -47-

or Fundamental Purchase Price, including Cash in lieu of any fractional shares)
or redemption pursuant to Section 4.02 if there has occurred prior to, on or
after, as the case may be, the giving, by the Holders of such Notes, of the
required Purchase Notice (or Fundamental Change Purchase Notice, as the case may
be) and is continuing an Event of Default (other than a default in the payment
of the Purchase Price or Fundamental Change Purchase Price, as the case may be,
and any accrued and unpaid contingent interest with respect to such Notes). The
Paying Agent will promptly return to the respective Holders thereof any Notes
(x) with respect to which a Purchase Notice or Fundamental Change Purchase
Notice, as the case may be, has been withdrawn in compliance with this
Supplemental Indenture, or (y) held by it during the continuance of an Event of
Default (other than a default in the payment of the Purchase Price or
Fundamental Change Purchase Price, as the case may be, and any accrued and
unpaid contingent interest with respect to such Notes) in which case, upon such
return, the Purchase Notice or Fundamental Change Purchase Notice with respect
thereto shall be deemed to have been withdrawn.

          (b) Deposit of Purchase Price or Fundamental Change Purchase Price.
              --------------------------------------------------------------
On or before 11:00 a.m.  (New York City time) on a Purchase Date or a
Fundamental Change Purchase Date, as the case may be, the Company shall deposit
with the Trustee or with the Paying Agent (or, if the Company or an Affiliate of
the Company is acting as the Paying Agent, shall segregate and hold in trust) an
amount of money and/or Common Stock, if permitted hereunder, sufficient to pay
the aggregate Purchase Price or Fundamental Change Purchase Price, as the case
may be, of, and any accrued and unpaid contingent interests, with respect to,
all the Notes or portions thereof which are to be purchased as of such Purchase
Date or Fundamental Change Redemption Date, as the case may be.

          (c) Notes Purchased in Part.  Any Note that is to be purchased only in
              -----------------------
part shall be surrendered at the office of the Paying Agent (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or such Holder's attorney duly authorized in writing) and
the Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Note, without service charge, a new Note or Notes, of any
authorized denomination as requested by such Holder in aggregate Principal
Amount at Final Maturity equal to, and in exchange for, the portion of the
Principal Amount at Final Maturity of the Note so surrendered which is not
purchased or redeemed.

          (d) Covenant to Comply with Securities Laws Upon Purchase of Notes.
              --------------------------------------------------------------
In connection with any offer to purchase Notes under Sections 4.02 or 4.03
hereof, the Company shall (i) comply with Rules 13e-4 and 14e-1 (which terms, as
used herein, include any successor provision thereto) under the Securities
Exchange Act of 1934, if applicable; (ii) file the related Schedule TO (or any
successor schedule, form or report) under the Securities Exchange Act of 1934,
if applicable; and (iii) otherwise comply with all federal and state securi-
<PAGE>

                                      -48-

ties laws so as to permit the rights and obligations under Sections 4.02 and
4.03 to be exercised in the time and in the manner specified in Sections 4.02
and 4.03.

          (e) Repayment to the Company.  The Trustee and the Paying Agent shall
              ------------------------
return to the Company any cash or shares of Common Stock that remain unclaimed
as provided in paragraph 15 of the Notes, together with interest that the
Trustee has agreed to pay, if any, or dividends, if any, paid thereon while such
shares are held by the Trustee or the Paying Agent, held by them for the payment
of a Purchase Price or Fundamental Change Purchase Price, as the case may be or
contingent interest, if any; provided, however, that to the extent that the
                             --------  -------
aggregate amount of cash or shares of Common Stock deposited by the Company
pursuant to Section 4.04(b) exceeds the aggregate Purchase Price or Fundamental
Change Purchase Price, as the case may be, of, and any accrued and unpaid
contingent interest with respect to the Notes or portions thereof which the
Company is obligated to purchase as of the Purchase Date or Fundamental Change
Purchase Date, as the case may be, then promptly after the Business Day
following the Purchase Date or Fundamental Change Purchase Date, as the case may
be, the Trustee and the Paying Agent shall return any such excess to the Company
together with interest that the Trustee has agreed to pay, if any, or dividends,
if any, paid thereon while such shares are held by the Trustee or the Paying
Agent.

Section 4.05.  Conversion of Notes.
               -------------------

          (a) Right to Convert.  A Holder of a Note may convert such Note for
              ----------------
Common Stock at any time during which the conditions stated in paragraph 10 of
the Notes are met.  The number of shares of Common Stock issuable upon
conversion of a Note per $1,000 of Principal Amount at Final Maturity (the

"Conversion Rate") shall be that set forth in paragraph 10 in the Notes, subject
----------------
to adjustment as herein set forth.

          A Holder may convert a portion of the Principal Amount at Final
Maturity of a Note if the portion is $1,000 or a multiple of $1,000.  Provisions
of this Supplemental Indenture that apply to conversion of all of a Note also
apply to conversion of a portion of a Note.

          (b) Conversion Procedures.  To convert a Note a Holder must satisfy
              ---------------------
the requirements in paragraph 10 of the Notes.  The date on which the Holder of
Notes satisfies all those requirements is the conversion date (the "Conversion
                                                                    ----------
Date").  As soon as practicable, but in no event later than the fifth Business
----
Day following the Conversion Date the Company shall deliver to the Holder,
through the Conversion Agent, a certificate for the number of full shares of
Common Stock issuable upon the conversion and Cash in lieu of any fractional
share determined pursuant to Section 4.05(c).  The Person in whose name the
certificate is registered shall be treated as a stockholder of record on and
after the Conversion Date; provided, however, that no surrender of a Note on any
                           --------  -------
date when the stock transfer books of the Company shall be closed shall be
effective to constitute the Person or Persons entitled to receive the shares of
Common Stock upon such conversion as the record holder or holders of such shares
of Common Stock on such date, but such surrender shall be effective to
constitute
<PAGE>

                                      -49-

the Person or Persons entitled to receive such shares of Common Stock as the
record holder or holders thereof for all purposes at the close of business on
the next succeeding day on which such stock transfer books are open; such
conversion shall be at the Conversion Rate in effect on the date that such Note
shall have been surrendered for conversion, as if the stock transfer books of
the Company had not been closed. Upon conversion of a Note, such Person shall no
longer be a Holder of such Note.

          No payment or adjustment shall be made for dividends on or other
distributions with respect to any Voting Stock except as provided in Section
4.06.  On conversion of a Note, that portion of Accreted Value (or interest, if
the Company has exercised its option pursuant to Section 4.06) attributable to
the period from the Issue Date of the Note to the Conversion Date and (except as
provided below) accrued contingent interest with respect to the converted Note
shall not be canceled, extinguished or forfeited, but rather shall be deemed to
be paid in full to the Holder thereof through delivery of the Common Stock
(together with the Cash payment, if any, in lieu of fractional shares) in
exchange for the Note being converted.

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

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

          If the last day on which a Note may be converted is a legal holiday in
a place where a Conversion Agent is located, the Note may be surrendered to that
Conversion Agent on the next succeeding day that it is not a legal holiday.

          (c) Cash Payments in Lieu of Fractional Shares.  The Company shall not
              ------------------------------------------
issue a fractional share of Common Stock upon conversion of a Note.  Instead the
Company shall deliver Cash for the current market value of the fractional share.
The current market value of a fractional share shall be determined to the
nearest 1/10,000th of a share by multiplying the Market Price of a full share of
Common Stock by the fractional amount and rounding the product to the nearest
whole cent.

          (d) Taxes on Conversion.  If a Holder converts a Note, 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 Holder requests the shares to be
issued in a name other than the Holder's name.  The Conversion Agent may refuse
to deliver the certificates representing the Common Stock being issued in a name
other than the Holder's name until the Conversion Agent receives a sum
sufficient to pay any tax which shall be due because the shares are to be issued
in
<PAGE>

                                      -50-

a name other than the Holder's name. Nothing herein shall preclude any tax
withholding required by law or regulations.

          (e) Company to Provide Stock.  The Company shall, prior to issuance of
              ------------------------
any Notes hereunder, and from time to time as may be necessary, reserve out of
its authorized but unissued Common Stock a sufficient number of shares of Common
Stock to permit the conversion of the Notes.

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

          The Company shall endeavor promptly to comply with all federal and
state securities laws regulating the order and delivery of shares of Common
Stock upon the conversion of Notes, if any, and shall cause to have listed or
quoted all such shares of Common Stock on each United States national securities
exchange or over-the-counter or other domestic market on which the Common Stock
is then listed or quoted.

Section 4.06.  Adjustments to Conversion Rate.
               ------------------------------

          The Conversion Rate shall be adjusted from time to time by the Company
as follows:

          (a) In case the Company shall (i) pay a dividend, or make a
     distribution, in shares of Common Stock or other capital stock, on Common
     Stock; (ii) subdivide its outstanding Common Stock into a greater number of
     shares; or (iii) combine its outstanding Common Stock into a smaller number
     of shares, the Conversion Rate in effect immediately prior thereto shall be
     adjusted so that the holder of any Note thereafter surrendered for
     conversion shall be entitled to receive the number of shares of Common
     Stock of the Company which such holder would have owned or have been
     entitled to receive after the happening of any of the events described
     above had such Note been converted immediately prior to the happening of
     such event.  If any dividend or distribution of the type described in
     clause (i) above is not so paid or made, the Conversion Rate shall again be
     adjusted to the Conversion Rate which would then be in effect if such
     dividend or distribution had not been declared.  An adjustment made
     pursuant to this Section 4.06 shall become effective immediately after the
     Record Date in the case of a dividend and shall become effective
     immediately after the effective date in the case of subdivision or
     combination.

          (b) In case the Company shall issue rights or warrants to all holders
     of any class or series of its Voting Stock entitling them (for a period
     expiring within 60 days after the date fixed for determination of
     stockholders entitled to receive such rights or warrants) to subscribe for
     or purchase Voting Stock at a price per share less than the
<PAGE>

                                      -51-

     Sale Price per share of Common Stock at the Record Date for the
     determination of stockholders entitled to receive such rights or warrants,
     the Conversion Rate in effect immediately prior thereto shall be adjusted
     so that the same shall equal the Conversion Rate determined by multiplying
     the Conversion Rate in effect immediately prior to the date of the issuance
     of such rights or warrants by a fraction of which the numerator shall be
     the number of shares of Voting Stock outstanding on the date of issuance of
     such rights or warrants plus the number of additional shares of Voting
     Stock offered for subscription or purchase, and of which the denominator
     shall be the number of shares of Voting Stock outstanding on the date of
     issuance of such rights or warrants plus the number of shares which the
     aggregate offering price of the total number of shares so offered would
     purchase at such Sale Price. Such adjustment shall be made successively
     whenever any such rights or warrants are issued, and shall become effective
     immediately after the opening of business on the day following the Record
     Date for the determination of the stockholders entitled to receive such
     rights or warrants. To the extent that shares of Voting Stock are not
     delivered after the expiration of such rights or warrants, the Conversion
     Rate shall be readjusted to the Conversion Rate which would then be in
     effect had the adjustments made upon the issuance of such rights or
     warrants been made on the basis of delivery of only the number of shares of
     Voting Stock actually delivered. If such rights or warrants are not so
     issued, the Conversion Rate shall again be adjusted to be the Conversion
     Rate which would then be in effect if such Record Date for the
     determination of stockholders entitled to receive such rights or warrants
     had not been fixed. In determining whether any rights or warrants entitle
     the holders to subscribe for or purchase shares of Voting Stock at less
     than such Sale Price, and in determining the aggregate offering price of
     such shares of Voting Stock, there shall be taken into account any
     consideration received by the Company for such rights or warrants, the
     value of such consideration, if other than cash, to be determined by the
     Board of Directors.

          (c) In case the Company shall, by dividend or otherwise, distribute to
     all holders of its Voting Stock (excluding any distribution in connection
     with the liquidation, dissolution or winding up of the Company, whether
     voluntary or involuntary) any shares of any class of capital stock of the
     Company (other than Voting Stock) or evidences of its indebtedness or
     assets (other than Cash) or rights or warrants to subscribe for or purchase
     any of its Notes (excluding those referred to in Section 4.06(b) hereof)
     (any of the foregoing hereinafter in this Section 4.06(c) called the

     "Distributed Securities"), then, the Conversion Rate shall be adjusted so
     -----------------------
     that the same shall equal the Conversion Rate determined by multiplying the
     Conversion Rate in effect immediately prior to the date of such
     distribution by a fraction of which the numerator shall be the Market Price
     per share of the Common Stock on the Record Date mentioned below, and the
     denominator shall be the Market Price per share of the Common Stock on such
     Record Date less the fair market value on such Record Date (as determined
     by the Board of Directors, whose determination shall be conclusive, and
     described in a
<PAGE>

                                      -52-

     certificate filed with the Trustee) of the Distributed Securities so
     distributed applicable to one share of Voting Stock. Such adjustment shall
     become effective immediately after the Record Date for the determination of
     stockholders entitled to receive such distribution. Notwithstanding the
     foregoing, in the event the then fair market value (as so determined) of
     the portion of the Distributed Securities so distributed applicable to one
     share of Voting Stock is equal to or greater than the Market Price of the
     Common Stock on the Record Date, in lieu of the foregoing adjustment,
     adequate provision shall be made so that each Holder shall have the right
     to receive upon conversion the amount of Distributed Securities such Holder
     would have received had such Holder converted each Note on such Record
     Date. In the event that such distribution is not so paid or made, the
     Conversion Rate shall again be adjusted to the Conversion Rate which would
     then be in effect if such distribution had not been declared. If the Board
     of Directors determines the fair market value of any distribution for
     purposes of this Section 4.06(c) by reference to the actual or when issued
     trading market for any Notes, it must in doing so consider the prices in
     such market over the same period used in computing the Market Price of the
     Common Stock.

          Notwithstanding the foregoing provisions of this Section 4.06(c), no
     adjustment shall be made thereunder for any distribution of Distributed
     Securities if the Company makes proper provision so that each Holder of a
     Note who converts such Note (or any portion thereof) after the Record Date
     for such distribution shall be entitled to receive upon such conversion, in
     addition to the shares of Common Stock issuable upon such conversion, the
     amount and kind of Distributed Securities that such Holder would have been
     entitled to receive if such Holder had, immediately prior to such Record
     Date, converted such Note for Common Stock; provided that, with respect to
     any Distributed Securities that are convertible, exchangeable or
     exercisable, the foregoing provision shall only apply to the extent (and so
     long as) the Distributed Securities receivable upon conversion of such Note
     would be convertible, exchangeable or exercisable, as applicable, without
     any loss of rights or privileges for a period of at least 60 days following
     conversion of such Note.

          Upon conversion of the Notes the Holders shall receive, in addition to
     the Common Stock issuable upon such conversion, the rights issued under the
     Company's existing stockholder rights plan and any future stockholder
     rights plan the Company implements (notwithstanding the occurrence of an
     event causing such rights to separate from the Common Stock at or prior to
     the time of conversion).

          (d) In case the Company shall, by dividend or otherwise, distribute to
     all holders of any class of its Voting Stock cash (excluding any cash that
     is distributed upon a merger or consolidation to which Section 4.07(f)
     applies or as part of a distribution referred to in Section 4.06(c)) in an
     aggregate amount that, combined together with (i) the aggregate amount of
     any other such distributions to all holders of any class
<PAGE>

                                      -53-

     of its Voting Stock made exclusively in cash within the 12 months preceding
     the date of payment of such distribution, and in respect of which no
     adjustment pursuant to this Section 4.06(d) has been made, and (ii) the
     aggregate of any cash plus the fair market value of consideration payable
     in respect of any tender offer by the Company for all or any portion of any
     class of its Voting Stock concluded within the 12 months preceding the date
     of payment of such distribution, and in respect of which no adjustment
     pursuant to Section 4.06(c) has been made, exceeds 10% of the product of
     the Market Price (determined as provided herein) on the Record Date with
     respect to such distribution times the number of shares of Voting Stock
     outstanding on such date, then, and in each such case, immediately after
     the close of business on such date, the Conversion Rate shall be increased
     so that the same shall equal the Conversion Rate determined by multiplying
     the Conversion Rate in effect immediately prior to the record date by a
     fraction of which the numerator shall be such Market Price of the Common
     Stock and the denominator shall be the Market Price of the Common Stock on
     the record date less the amount of cash so distributed (and not excluded as
     provided above) applicable to one share of Voting Stock, such increase to
     be effective immediately prior to the opening of business on the day
     following the record date and the number of shares of Voting Stock
     outstanding on the Record Date; provided, however, that no adjustment will
                                     --------  -------
     be made in respect of any such dividends and distributions that result in
     the payment of any contingent interest to the Holders; provided, further,
                                                            --------  -------
     that, if the portion of the cash so distributed applicable to one share of
     Voting Stock is (i) equal to or greater than the Market Price of the Common
     Stock on the Record Date or (ii) the Market Price of the Common Stock on
     the Record Date is greater than the fair market value of the evidences of
     indebtedness, assets, rights and warrants distributed pursuant to Section
     4.06(c) by less than $1.00, then, in lieu of the foregoing adjustment,
     adequate provision shall be made so that each Holder shall have the right
     to receive upon conversion, in addition to the shares of Common Stock, the
     kind and amount of assets, debt securities, or rights warrants or options
     the Holder would have received had such Holder converted such Note
     immediately prior to such Record Date. If such dividend or distribution is
     not so paid or made, the Conversion Rate shall again be adjusted to be the
     Conversion Rate which would then be in effect if such dividend or
     distribution had not been declared. If any adjustment is required to be
     made as set forth in this Section 4.06(d) as a result of a distribution
     that is a quarterly dividend, such adjustment shall be based upon the
     amount by which such distribution exceeds the amount of the quarterly cash
     dividend permitted to be excluded pursuant hereto. If an adjustment is
     required to be made as set forth in this Section 4.06(d) above as a result
     of a distribution that is not a quarterly dividend, such adjustment shall
     be based upon the full amount of the distribution.

          (e) In case a tender offer made by the Company or any of its
     subsidiaries for all or any portion of any class of its Voting Stock
     expires and such tender offer (as amended upon the expiration thereof)
     requires the payment to stockholders (based on
<PAGE>

                                      -54-

     the acceptance (up to any maximum specified in the terms of the tender
     offer) of Purchased Shares) of an aggregate consideration having a fair
     market value (as determined by the Board of Directors, whose determination
     shall be conclusive and described in a resolution of the Board of
     Directors) that, combined together with (a) the aggregate of the cash plus
     the fair market value (as determined by the Board of Directors, whose
     determination shall be conclusive and described in a resolution of the
     Board of Directors), as of the expiration of such tender offer, of
     consideration payable in respect of any other tender offers, by the Company
     or any of its subsidiaries for all or any portion of any class of its
     Voting Stock expiring within the 12 months preceding the expiration of such
     tender offer and in respect of which no adjustment pursuant to this Section
     4.06(e) has been made, and (b) the aggregate amount of any distributions to
     all holders of the Voting Stock made exclusively in cash within 12 months
     preceding the expiration of such tender offer and in respect of which no
     adjustment pursuant to Section 4.06(d) has been made, exceeds 10% of the
     product of the Market Price (determined as provided herein) as of the last
     time (the "Expiration Time") tenders could have been made pursuant to such
                ---------------
     tender offer (as it may be amended) times the number of shares of Voting
     Stock outstanding (including any tendered shares) at the Expiration Time,
     then, and in each such case, immediately prior to the opening of business
     on the day after the date of the Expiration Time, the Conversion Rate shall
     be increased so that the same shall equal the Conversion Rate determined by
     multiplying the Conversion Rate in effect immediately prior to the
     Expiration Time by a fraction of which the numerator shall be the number of
     shares of Voting Stock outstanding (including any tendered or exchanged
     shares) on the Expiration Time multiplied by the Market Price of the Common
     Stock on the Trading Day next succeeding the Expiration Time and the
     denominator shall be the sum of (x) the fair market value (determined as
     aforesaid) of the aggregate consideration payable to stockholders based on
     the acceptance (up to an maximum specified in the terms of the tender or
     exchanged offer) of all shares validly tendered or exchanged and not
     withdrawn as of the Expiration Time (the shares deemed so accepted, up to
     any such maximum, being referred to as the "Purchased Shares") and (y) the
                                                 ----------------
     product of the number of shares of Voting Stock outstanding (less any
     Purchased Shares) on the Expiration Time and the Market Price of the Common
     Stock on the Trading Day next succeeding the Expiration Time such reduction
     (if any) to become effective immediately prior to the opening of business
     on the day following the Expiration Time. If the Company is obligated to
     purchase shares pursuant to any such tender offer, but the Company is
     permanently prevented by applicable law from effecting any such purchases
     or all such purchases are rescinded, the Conversion Rate shall again be
     adjusted to be the Conversion Rate which would then be in effect if such
     tender offer had not been made.

          (f) For purposes of this Section 4.06, the number of shares of Voting
     Stock at any time outstanding shall not include shares held in the treasury
     of the Company but shall include shares issuable in respect of scrip
     certificates issued in lieu of frac-
<PAGE>

                                      -55-

     tions of shares of Voting Stock. The Company shall not pay any dividend or
     make any distribution on shares of Voting Stock held in the treasury of the
     Company.

Section 4.07.  Miscellaneous Provisions Relating to Conversion.
               -----------------------------------------------

          (a) When Adjustment May be Deferred.  No adjustment in the Conversion
              -------------------------------
Rate need be made unless the adjustment would require an increase or decrease of
at least 1% in the Conversion Rate then in effect provided that any adjustment
that would otherwise be required to be made shall be carried forward and taken
into account in any subsequent adjustment.  Except as stated in Section 4.06,
the Conversion Rate will not be adjusted for the issuance of Voting Stock or any
securities convertible into or exchangeable for Voting Stock or carrying the
right to purchase any of the foregoing.  Any adjustments that are made shall be
carried forward and taken into account any subsequent adjustment.  All
calculations under Sections 4.05, 4.06 and 4.07 shall be made to the nearest
cent or to the nearest 1/10,000th of a share, as the case may be.

          (b) When No Adjustment Required.  No adjustment need be made for
              ---------------------------
rights to purchase Voting Stock pursuant to a Company plan for reinvestment of
dividends or interest.  No adjustment need be made for a change in the par value
or no par value of the Voting Stock.  To the extent the Notes become convertible
into cash, assets, property or Notes (other than capital stock of the Company),
no adjustment need be made thereafter as to the cash, assets, property or such
Notes.  Interest shall not accrue on the cash.

          (c) 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 and the Conversion Agent such notice.  The
certificate shall, absent manifest error, be conclusive evidence that the
adjustment is correct.  Neither than Trustee nor any Conversion Agent shall be
under any duty or responsibility with respect to any such certificate except to
exhibit the same to any Holder desiring inspection thereof.

          (d) Voluntary Increase.  The Company may make such increases in the
              ------------------
Conversion Rate, in addition to those required by Section 4.06, as the Board of
Directors considers to be advisable to avoid or diminish any income tax to
holders of Voting Stock or rights to purchase Voting Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated as such for income tax purposes.  To the extent permitted by applicable
law, the Company may from time to time increase the Conversion Rate by any
amount for any period of time if the period is at least 20 days, the increase is
irrevocable during the period and the Board of Directors shall have made a
determination that such increase would be in the best interests of the Company,
which determination shall be conclusive.  Whenever the Conversion Rate is so
increased, the Company shall mail to Holders and file with the Trustee and the
Conversion Agent a notice of such increase.  Neither the Trustee nor any
Conversion Agent shall be under any duty or responsibility with respect to any
such certificate except to exhibit the same to any holder desiring inspection
thereof.  The Company
<PAGE>

                                      -56-

shall mail the notice at least 15 days before the date the increased Conversion
Rate takes affect. The notice shall state the increased Conversion Rate and the
period it shall be in effect.

          (e) Notice to Holders Prior to Certain Actions.  In case:
              ------------------------------------------

          (i)    the Company shall declare a dividend (or any other
     distribution) on its Voting Stock that would require an adjustment in the
     Conversion Rate pursuant to Section 4.06;

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

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

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

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

          (f) Effect of Reclassification, Consolidation, Merger or Sale.  If any
              ---------------------------------------------------------
of the following events occur, namely (i) any reclassification or change of
outstanding shares of Voting Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination); (ii) any consolidation, merger or combination of
the Company with another corporation as a result of which holders of Voting
Stock shall be entitled to receive stock, Notes or other property or assets
(including
<PAGE>

                                      -57-

cash) with respect to or in exchange for such Voting Stock; or (iii) any sale or
conveyance of the properties and assets of the Company as, or substantially as,
an entirety to any other corporation as a result of which holders of Voting
Stock shall be entitled to receive stock, Notes or other property or assets
(including cash) with respect to or in exchange for such Voting Stock, then the
Company or the successor or purchasing corporation, as the case may be, shall
execute with the Trustee a supplemental indenture, providing that each Note
shall be convertible into the kind and amount of shares of stock and other Notes
or property or assets (including cash) receivable upon such reclassification,
change, consolidation, merger, combination, sale or conveyance by a holder of a
number of shares of Voting Stock issuable upon conversion of such Notes
immediately prior to such reclassification, change, consolidation, merger,
combination, sale or conveyance. Such supplemental indenture shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 4.07(f).

          The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder of Notes, at his address appearing on the
Note register, within 20 days after execution thereof.  Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture.

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

          If this Section 4.07(f) applies to any event or occurrence, Section
4.06 shall not apply.

          (g) Responsibility of Trustee.  The Trustee and any other Conversion
              -------------------------
Agent shall not at any time be under any duty or responsibility to any Holder of
Notes to either calculate the Conversion Rate or determine whether any facts
exist which may require any adjustment of the Conversion Rate, or with respect
to the nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same and shall be protected in relying
upon an Officer's Certificate with respect to the same.  The Trustee and any
other Conversion Agent shall not be accountable with respect to the validity or
value (or the kind or amount) of any shares of Common Stock, or of any
securities or property, which may at any time be issued or delivered upon the
conversion of any Note and the Trustee and any other Conversion Agent make no
representations with respect thereto.  Subject to the provisions of Article
Seven of the Indenture, neither the Trustee nor any Conversion Agent shall be
responsible for any failure of the Company to issue, transfer or deliver any
shares of Common Stock or stock certificates or other securities or property or
cash upon the surrender of any Note for the purpose of conversion or to comply
with any of the duties, responsibilities or covenants of the Company contained
in this Section.  Without limiting the generality of the foregoing, neither the
Trustee nor any Conversion Agent shall be under any responsibility to determine
<PAGE>

                                      -58-

the correctness of any provisions contained in any supplemental indenture
entered into pursuant to Section 4.07(f) relating either to the kind or amount
of shares of stock or securities or property (including cash) receivable by
Holders upon the conversion of their Notes after any event referred to in such
Section 4.07(f) or to any adjustment to be made with respect thereto, but,
subject to the provisions of Article Seven of the Indenture, may accept as
conclusive evidence of the correctness of any such provisions, and shall be
protected in relying upon, the Officer's Certificate (which the Company shall be
obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

          (h) Simultaneous Adjustments.  In the event that Sections 4.05, 4.06
              ------------------------
or 4.07 require adjustments to the Conversion Rate under more than one of
Section 4.06(a), (b), (c) or (d), and the Record Dates for the distributions
giving rise to such adjustments shall occur on the same date, then such
adjustments shall be made by applying, first, the provisions of Section 4.06(c),
second, the provisions of Section 4.06(d), third, the provisions of Section
4.06(a), and fourth, the provisions of Section 4.06(b).

          (i) Successive Adjustments.  After an adjustment to the Conversion
              ----------------------
Rate under Sections 4.05, 4.06 or 4.07, any subsequent event requiring an
adjustment under Sections 4.05, 4.06 or 4.07 shall cause an adjustment to the
Conversion Rate as so adjusted.

          (j) General Considerations.  Whenever successive adjustments to the
              ----------------------
Conversion Rate are called for pursuant to Sections 4.05, 4.06 or 4.07, such
adjustments shall be made to the Market Price as may be necessary or appropriate
to effectuate the intent of Sections 4.05, 4.06 or 4.07 and to avoid unjust or
inequitable results as determined in good faith by the Board of Directors.

Section 4.08.  Optional Conversion to Semi-Annual Cash Pay Note Upon Tax Event.
               ---------------------------------------------------------------

          From and after (i) the date (the "Tax Event Date") of the occurrence
                                            --------------
of a Tax Event and (ii) the date the Company exercises its option set forth in
this 4.08, whichever is later (the "Option Exercise Date"), at the option of the
                                    --------------------
Company, cash interest in lieu of future Accreted Value shall accrue at the rate
of 3.25% per annum on a restated principal amount per $1,000 original Principal
Amount at Final Maturity (the "Restated Principal Amount") equal to its Accreted
                               -------------------------
Value on the Option Exercise Date and shall be payable semi-annually on May 11
and November 11 of each year (each an "Interest Payment Date") to holders of
                                       ---------------------
record at the close of business on April 27 and October 28 (each a "Regular
                                                                    -------
Record Date") immediately preceding such Interest Payment Date.  Interest will
-----------
be computed on the basis of a 360-day year comprised of twelve 30-day months and
will accrue from the most recent date on which interest has been paid or, if no
interest has been paid, from the Option Exercise Date.  Within 15 days of the
occurrence of a Tax Event, the Company shall deliver a written notice of such
Tax Event by facsimile and first-class mail to the Trustee and within 15 days of
their exercise of such option the Company shall deliver a written notice of the
Option Exercise
<PAGE>

                                      -59-

Date by facsimile and first-class mail to the Trustee and by first-class mail to
the Holders of the Notes. From and after the Option Exercise Date, (i) the
Company shall be obligated to pay at Maturity or upon a Redemption Date,
Purchase Date or Fundamental Change Purchase Date, in lieu of the Principal
Amount at Final Maturity of a Note, the Restated Principal Amount thereof plus
accrued and unpaid interest, (ii) "Accreted Value" or similar words, as used
herein, means Restated Principal Amount plus accrued and unpaid interest with
respect to any Note, and (iii) contingent interest shall cease to accrue on the
Notes. Notes authenticated and delivered after the Option Exercise Date may, and
shall if required by the Trustee, bear a notation in a form approved by the
Trustee as to the conversion of the Notes to semi-annual cash pay notes.

Section 4.09.  Calculation of Original Issue Discount for U.S. Federal Income
               Tax Purposes.
               --------------------------------------------------------------

          The Company agrees, and each Holder and any beneficial holder of a
Note by its purchase thereof shall be deemed to agree, to treat (in the absence
of an administrative determination or judicial ruling to the contrary), for
United States federal income tax purposes, the Notes as debt instruments that
are subject to Section 1.1275-4(b) of the Treasury Regulations.  For United
States federal income tax purposes, the Company shall accrue interest with
respect to outstanding Notes as original issue discount according to the
"noncontingent bond method," set forth in Section 1.1275-4(b) of the Treasury
Regulations, based on a comparable yield of 8.88% compounded semi-annually and
the projected payment schedule attached hereto as Exhibit B.  The Company shall
file with the Trustee promptly at the end of each calendar year:  (i) a written
notice specifying the amount of original issue discount for United States
federal income tax purposes (including daily rates and accrual periods) accrued
on outstanding Notes as of the end of such year and (ii) such other specific
information relating to such original issue discount as may then be relevant
under the Internal Revenue Code of 1986, as amended from time to time, including
the amount of any adjustment made under the noncontingent bond method to account
for the amount of any difference between the amount of an actual payment and the
amount of a projected payment.

          The Company acknowledges and agrees, and each Holder and any
beneficial holder of a Note by its purchase thereof shall be deemed to
acknowledge and agree, that (i) the comparable yield means the annual yield the
Company would pay, as of the Issue Date, on a fixed-rate cash pay nonconvertible
debt security with no contingent payments, but with terms and conditions
otherwise comparable to those of the Notes; (ii) the schedule of projected
payments attached hereto as Exhibit B is determined on the basis of the
comparable yield and an assumption of linear growth of the stock price and a
constant dividend yield; (iii) the comparable yield and the schedule of
projected payments are not determined for any purpose other than for the
determination of interest accruals and adjustments thereof in respect of the
Notes for United States federal income tax purposes; and (iv) the comparable
yield and the schedule
<PAGE>

                                      -60-

of projected payments do not constitute a projection or representation regarding
the future stock price or the amounts payable on the Notes.

Section 4.10.  Payment of Interest.
               -------------------

          (a) Paying Agent To Hold Money in Trust.  Prior to 11:00 a.m.  (New
              -----------------------------------
York City time) on any applicable payment date, the company shall deposit with
the Paying Agent (or if an Issuer or a Subsidiary of any Issuer is acting as
Paying Agent, segregate and hold in trust for the benefit of the Persons
entitled thereto) a sum sufficient to pay semi-annual or contingent interest
when due.  The Company shall require each Paying Agent (other than the Trustee)
to agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal or interest on the Notes and shall notify the Trustee of any default
by the Company in making any such payment.  If the Company or a Subsidiary acts
as Paying Agent, it shall segregate the money held by it as Paying Agent and
hold it as a separate trust fund.  The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee and to account for any funds
disbursed by the Paying Agent.  Upon complying with this Section, the Paying
Agent shall have no further liability for the money delivered to the Trustee.

          (b) Holder 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, or cause the Registrar to furnish, to the Trustee, in writing at least
five Business Days before 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 may reasonably require of the names and addresses of Holders.

          (c) Payment of Interest; Interest Rights Preserved.  (i) Semi-annual
              ----------------------------------------------
or contingent interest on any Note that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Note is registered at the close of business on the Regular
Record Date or accrual date, as the case may be, for such interest at the office
or agency of the Company maintained for such purpose.  Each installment of semi-
annual or contingent interest on any Note shall be paid in same-day funds by
transfer to an account maintained by the payee located inside the United States.
In the case of a Global Note, semi-annual or contingent interest payable on any
applicable payment date will be paid to the Depositary, with respect to that
portion of such Global Note held for its account by Cede & Co.  for the purpose
of permitting such party to credit the interest received by it in respect of
such Global Note to the accounts of the beneficial owners thereof.

          (ii)   Except as otherwise specified with respect to the Notes, any
semi-annual or contingent interest on any Note that is payable, but is not
punctually paid or duly provided for, within 30 days following any applicable
payment date (herein called "Defaulted Interest", which term shall include any
                             ------------------
accrued and unpaid interest that has accrued on such defaulted amount in
accordance with paragraph 1 of the Notes), shall forthwith cease to be
<PAGE>

                                      -61-

payable to the registered Holder thereof on the relevant Regular Record Date or
accrual date, as the case may be, 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 (A) or (B) below.

          (A) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Notes are registered at the close of
     business on a date for the payment of such Defaulted Interest (the "Special
                                                                         -------
     Record Date"), 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 Note and the date of the proposed payment
     (which shall not be less than 20 days after such notice is received by the
     Trustee), and at the same time the Company shall deposit with the Trustee
     an amount of money equal to the aggregate amount proposed to be paid in
     respect of such Defaulted Interest or shall make arrangements satisfactory
     to the Trustee for such deposit on or prior to the date of the proposed
     payment, such money when deposited to be held in trust for the benefit of
     the Persons entitled to such Defaulted Interest as in this clause provided.
     Thereupon the 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 of Notes at his address as it appears on the list of Holders
     maintained pursuant to this Supplemental Indenture not less than 10 days
     prior to such Special Record Date.  Notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor having been mailed
     as aforesaid, such Defaulted Interest shall be paid to the Persons in whose
     names the Notes are registered at the close of business on such Special
     Record Date and shall no longer be payable pursuant to the following clause
     (B).

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

          Subject to the foregoing provisions of this Section 4.10 and Section
[3.02], each Note delivered under this Supplemental Indenture upon registration
of transfer of or in exchange for or in lieu of any other Note shall carry the
rights to semi-annual or contingent interest accrued and unpaid to, and to
accrue, which were carried by such other Note.

                       [FORM OF FACE OF GLOBAL SECURITY]

          For purposes of Sections 1273 and 1275 of the Internal Revenue Code,

commencement date for the accrual of original issue discount is May 11, 2001.
The yield to maturity for purposes of accruing original issue discount is 8.88%
per annum.

          This security is a global security within the meaning of the Indenture
hereinafter referred to and is registered in the name of a depository or a
nominee of a depository or a successor depository.  This security is not
exchangeable for securities registered in the name of a person other than the
depository or its nominee except in the limited circumstances described in the
Indenture, and no transfer of this security (other than a transfer of this
security as a whole by the depository to a nominee of the depository or by a

certificate issued is registered in the name of Cede & Co. or in such other name
as is requested by an authorized representative of DTC (and any payment is made
to Cede & Co. or to such other entity as is requested by an authorized
representative of DTC), any transfer, pledge or other use hereof for value or
otherwise by or to any person is wrongful inasmuch as the registered owner
hereof, Cede & Co., has an interest herein.

                  ZERO COUPON CONVERTIBLE SENIOR NOTE DUE 2021

          1.  INTEREST

          This Note shall not bear periodic interest, except as specified in
this paragraph and in paragraphs 5 and 11 hereof.  If the Principal hereof or
any portion of such Principal is not paid when due (whether upon acceleration
pursuant to the Indenture, upon the date set for payment of the Redemption Price
pursuant to paragraph 6 hereof, upon the date set for payment of a Purchase
Price or Fundamental Change Purchase Price pursuant to paragraph 7 hereof or
upon the Final Maturity of this Note) or if interest (including contingent
interest, if any) due hereon or any portion of such interest is not paid when
due in accordance with paragraph 5 or 11 hereof, then in each such case the
overdue amount shall bear interest at the rate of 3.25% per annum, compounded
semiannually (to the extent that the payment of such interest shall be legally
enforceable), which interest shall accrue from the date such overdue amount was
due to the date payment of such amount, including interest thereon, has been
made or duly provided for.  All such interest shall be payable on demand.  The
accrual of such interest on overdue amounts shall be in lieu of, and not in
addition to, the continued accretion.

          The Notes shall accrete daily at 3.25% per annum, on a semi-annual
bond equivalent basis using a 360-day year composed of twelve 30-day months,
commencing on the Issue Date of this Note.

          2.  METHOD OF PAYMENT

          Subject to the terms and conditions of the Indenture, the Company
shall make payments in respect of the Notes to the Persons who are registered
Holders of Notes at the close of business on the Business Day preceding the
Redemption Date or Final Maturity, as the case may be, or at the close of
business on a Purchase Date or Fundamental Change Purchase Date, as the case may
be.  Holders must surrender Notes to a Paying Agent to collect such payments in
respect of the Notes.  The Company shall pay cash amounts in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may make such cash payments by check
payable in such money.

          3.   PAYING AGENT, CONVERSION AGENT, BID AGENT AND REGISTRAR

          Initially, American Stock Transfer & Trust Company (the "Trustee"),
shall act as Paying Agent, Conversion Agent, Bid Agent and Registrar.  The
Company may  appoint
<PAGE>

                                      -5-

and change any Paying Agent, Conversion Agent, Bid Agent, Registrar or co-
registrar without notice, other than notice to the Trustee except that the
Company will maintain at least one Paying Agent in the State of New York, City
of New York, Borough of Manhattan, which shall initially be an office or agency
of the Trustee. The Company or any of its Subsidiaries or any of their
Affiliates may act as Paying Agent, Conversion Agent, Bid Agent, Registrar or
co-registrar.

          4.  INDENTURE

          The Company issued the Notes under an Indenture dated as of June 9,
1997 among the Company, the Guarantors and the Trustee, as supplemented (the
"Indenture").  The terms of the Notes and the Guarantees include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 ("TIA") as in effect on the date of the Indenture.  The
Notes and the Guarantees are subject to all such terms, and Securityholders are
referred to as the Indenture and the Act for a statement of them.  Capitalized
terms not defined herein have the meanings given to those terms in the
Indenture.

          The Company will furnish to any Securityholder upon written request
and without charge a copy of the Indenture and the applicable Authorizing
Resolution or supplemental indenture.  Requests may be made to:  D.R. Horton,
Inc., 1901 Ascension Blvd., Suite 100, Arlington, Texas 76006, Attention:  Chief
Financial Officer.

          5.  CONTINGENT INTEREST

          Subject to the accrual and record date provisions specified in this
paragraph 5, the Company shall pay contingent interest to the Holders during any
six-month period (a "Contingent Interest Period") from May 11 to November 10 and
from November 11 to May 10, commencing after May 11, 2003, if the average Note
Price for the Five-Day Period with respect to such Contingent Interest Period
equals 120% or more of the Accreted Value of such Note to the trading day
immediately preceding the first day of the relevant Contingent Interest Period.

          The amount of contingent interest payable per $1,000 Principal Amount
at Final Maturity hereof in respect of any Contingent Interest Period shall
equal the greater of (x) Cash Dividends paid by the Company per share of Common
Stock during that Contingent Interest Period multiplied by the number of shares
of Common Stock into which $1,000 Principal Amount at Final Maturity hereof is
convertible pursuant to paragraph 10 hereof as of the accrual date for such
contingent interest and (y) 0.125% of the average Note Price for the Five-Day
Period with respect to such Contingent Interest Period, except that no
contingent interest payment shall exceed 1.62% of the Accreted Value of the
Notes at the beginning of the relevant Contingent Interest Period.
<PAGE>

                                      -6-

          Contingent interest, if any, will accrue and be payable to Holders as
of the record date for the related Cash Dividend or, if no Cash Dividend is paid
by the Company during any quarter within a Contingent Interest Period, to
Holders as of the 15th day preceding the last day of the relevant Contingent
Interest Period.  Such payments shall be paid on the payment date of the related
Cash Dividend or, if no Cash Dividend is paid by the Company during any quarter
within a Contingent Interest Period, on the last day of the relevant Contingent
Interest Period.  In addition, on any Purchase Date, Fundamental Change Purchase
Date or Redemption Date that occurs during a Contingent Interest Period for
which a Holder is entitled to contingent interest pursuant to clause (y) of the
preceding paragraph, contingent interest will be payable to such Holder in an
amount equal to the amount that would have been otherwise payable to such Holder
on the last day of such Contingent Interest Period divided by the actual number
of days from the first day of such Contingent Interest Date to the Purchase
Date, Fundamental Change Purchase date or Redemption, as the case may be, using
a 360-day year composed of twelve 30-day months.

          "Five-Day Period" means, with respect to any Contingent Interest
Period, the five trading days ending on the second trading day immediately
preceding the first day of such Contingent Interest Period; provided, however,
if the Company shall have declared a Cash Dividend on its Common Stock that is
payable during such Contingent Interest Period but for which the record date for
determining stockholders entitled thereto precedes the first day of such
Contingent Interest Period, then "Five-Day Period" means, with respect to such
Contingent Interest Period, the five trading days ending on the second trading
day immediately preceding such record date.

          "Cash Dividends" means all cash dividends on the Company's common
stock (whether regular, periodic, extraordinary, special, nonrecurring or
otherwise) as declared by the Company's Board of Directors as part of its cash
dividend payment practices.

          "Note Price" means, as of any date of determination, the average of
the secondary market bid quotations per Note obtained by the Bid Agent for $10
million Principal Amount at Maturity of Notes at approximately 4:00 p.m. (New
York City time) on such determination date from three recognized securities
dealers in The City of New York (none of which shall be an Affiliate of the
Company) selected by the Company; provided, however, if (a) at least three such
bids are not obtained by the Bid Agent or (b) in the Company's reasonable
judgment, the bid quotations are not indicative of the secondary market value of
the Notes as of such determination date, then the Note Price for such
determination date shall equal (i) the Conversion Rate in effect as of such
determination date multiplied by (ii) the average Sale Price of Common Stock for
the five trading days ending on such determination date, appropriately adjusted
to take into account the occurrence, during the period commencing on the first
of such trading days during such five trading day period and ending on such
determination date, of any event described in Section 4.06(a), 4.06(b) or
4.06(c) (subject to the conditions set forth in Sections 4.07(a) and 4.07(b)) of
the Indenture.
<PAGE>

                                      -7-

          Upon determination that Holders will be entitled to receive contingent
interest which may become payable during a Contingent Interest Period, on or
prior to the first day of such Contingent Interest Period, the Company shall
issue a press release and publish such information on its web site so long as
such web site exists.

          6.  REDEMPTION AT THE OPTION OF THE COMPANY

          No sinking fund is provided for the Notes.  Beginning on May 11, 2003,
the Notes are redeemable as a whole, or from time to time in part, at any time
at the option of the Company at their Accreted Value.

          The table below shows the Accreted Value of a Note on the dates shown
below and at Final Maturity.  The Accreted Value, in dollars, of a Note per
$1,000 Principal Amount at Final Maturity redeemed between such dates shall
include an additional amount reflecting the increase in Accreted Value since the
next preceding date in the table to but excluding the actual Redemption Date.

cease to accrete and interest (including contingent interest), if any, will
cease to accrue on such Notes (or portions thereof) on and after such date, and
the Holder thereof shall have no other rights as such (other than the right to
receive the Purchase Price or Fundamental Change Purchase Price, as the case may
be, and accrued and unpaid contingent interest, if any, upon surrender or such
Note).

          9.  [INTENTIONALLY OMITTED]

          10.  CONVERSION

          A Holder of a Note may convert this Note for Common Stock of the
Company at any time on or before the close of business on May 11, 2021 if at
least one of the following conditions is satisfied:

          (a) the Twenty-Day Average Price on the Conversion Date is at least
     110% or more of the Accreted Conversion Price;

          (b) the credit rating assigned to the Notes by Moody's Investors
     Service, Inc. and Standard & Poor's Ratings Services are at least two
     levels lower than the initial credit ratings assigned by Moody's Investors
     Service, Inc. and Standard & Poor's Ratings Services (for the avoidance of
     doubt, the foregoing reference to "levels" is intended to refer to any
     subcategories such rating agencies employ in their announced ratings of
     securities, including plusses and minuses, but not including any
     characterization as to likelihood of future action in respect of
     securities' ratings);

          (c) the Notes have been called for redemption by the Company, at any
     time prior to the close of business on the Business Day prior to the
     Redemption Date; or

          (d) the Company elects (i) to distribute to all holders of Common
     Stock rights entitling them to purchase, for a period expiring within 60
     days after the date of such distribution, Common Stock at less than the
     Sale Price at the time of such distribution, (ii) to distribute to all
     holders of Common Stock assets, debt, securities or rights to purchase
     securities of the Company, which distribution has a per share value as
     determined by the Company's Board of Directors exceeding 15% of the Sale
     Price of the Common Stock on the day preceding the declaration date for
     such distribution, or (iii) in the event the Company is a party to a
     consolidation, merger or binding share exchange pursuant to which the
     Common Stock would be converted into cash, securities or other property, at
     any time from and after the date which is 15 days prior to the date the
     Company announces the anticipated effective time until 15 days after the
     actual effective date of such transaction.

          In the case of the foregoing clauses (d)(i) and (ii), the Company must
notify the Holders of Notes at least 20 days prior to the Ex-Dividend Date for
such distribution.  Once the Company has given such notice, Holders may
surrender their Notes for conversion at any
<PAGE>

                                     -11-

time thereafter until the earlier of the close of business on the Business Day
prior to the Ex-Dividend Date or the Company's announcement that such
distribution will not take place.

          If this Note is called for redemption, the Holder may convert it at
any time before the close of business on the last Business Day prior to the
Redemption Date.  A Note in respect of which a Holder has delivered a notice of
exercise of the option to require the Company to purchase such Note or to
purchase such Note in the event of a Fundamental Change may be converted only if
the notice of exercise is withdrawn in accordance with the terms of the
Indenture.

          The initial Conversion Rate is 17.4927 shares of Common Stock per Note
with a $1,000 Principal Amount at Final Maturity, subject to adjustment in
certain events described in the Indenture.  The Company shall deliver cash or a
check in lieu of any fractional share of Common Stock.

          In the event the Company exercises its option pursuant to Section 4.08
of the Indenture to convert the Notes to Cash Pay Notes, the Holder will be
entitled on conversion to receive the same number of shares of Common Stock such
Holder would have received if the Company had not exercised such option.  If the
Company exercises such option, Notes surrendered for conversion during the
period from the close of business on any Regular Record Date next preceding any
Interest Payment Date to the opening of business of such Interest Payment Date
(except Notes with respect to which the Company has mailed a notice of
redemption) must be accompanied by payment of an amount equal to the interest
thereon that the registered Holder is to receive.  Except where Notes
surrendered for conversion must be accompanied by payment as described above, no
interest on converted Notes will be payable by the Company on any Interest
Payment Date subsequent to the date of conversion.

          Notes surrendered for conversion during the period from the close of
business on any date on which contingent interest accrues to the opening of
business on the date on which such contingent interest is payable (except Notes
with respect to which the Company has mailed a notice of redemption) must be
accompanied by payment of an amount equal to the contingent interest with
respect thereto that the registered Holder is to receive.  Except where Notes
surrendered for conversion must be accompanied by payment as described above, no
contingent interest on converted Notes will accrue after the date of conversion.

          To convert this Note a Holder must (1) complete and manually sign the
conversion notice on the back of this Note (or complete and manually sign a
facsimile of such notice) and deliver such notice to the Conversion Agent at the
office maintained by the Conversion Agent for such purpose, (2) surrender this
Note to the Conversion Agent, (3) furnish appropriate endorsements and transfer
documents if required by the Conversion Agent, the Company or the Trustee and
(4) pay any transfer or similar tax, if required.
<PAGE>

                                     -12-

          A Holder may convert a portion of this Note only if the Principal
Amount at Final Maturity of such portion is $1,000 or a multiple of $1,000.  No
payment or adjustment shall be made for dividends on the Common Stock except as
provided in the Indenture.  On conversion of this Note, that portion of Accreted
Value (or, interest, if the Company has exercised its option provided for in
paragraph 11 hereof) attributable to the period from the Issue Date (or, if the
Company has exercised the option referred to in paragraph 11 hereof, the later
of (x) the date of such exercise and (y) the date on which interest was last
paid) to the Conversion Date and (except as provided below) accrued contingent
interest with respect to the converted portion of this Note shall not be
canceled, extinguished or forfeited, but rather shall be deemed to be paid in
full to the Holder thereof through the delivery of the Common Stock (together
with any cash payment in lieu of fractional shares) in exchange for the portion
of this Note being converted pursuant to the terms hereof; and the fair market
value of such shares of Common Stock (together with any such cash payment in
lieu of fractional shares) shall be treated as issued, to the extent thereof,
first in exchange for Accreted Value (or interest, if the Company has exercised
its option provided for in paragraph 11 hereof) accrued through the Conversion
Date and accrued contingent interest, and the balance, if any, of such fair
market value of such Common Stock (and any such cash payment) shall be treated
as issued in exchange for the Issue Price of the Note being converted pursuant
to the provisions hereof.

          11.  TAX EVENT

          (a) From and after (i) the date (the "Tax Event Date") of the
occurrence of a Tax Event and (ii) the date the Company exercises such option,
whichever is later (the "Option Exercise Date"), at the option of the Company,
all of the Notes will cease to accrete, and cash interest shall accrue at the
rate of 3.25% per annum on the restated principal amount (the "Restated
Principal Amount"), equal to the Accreted Value on the Option Exercise Date, and
shall be payable semiannually on May 11  and November 11 of each year (each an
"Interest Payment Date") to holders of record at the close of business on April
28 or October 29 (each a "Regular Record Date") immediately preceding such
Interest Payment Date.  Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months and will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the Option
Exercise Date.

          (b) Interest on any Note that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the person in
whose name that Note is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Company maintained
for such purpose.  Each installment of interest on any Note shall be paid in
same-day funds by transfer to an account maintained by the payee located inside
the United States.
<PAGE>

                                     -13-

          (c) From and after the Option Exercise Date, contingent interest
provided for in paragraph 5 hereof shall cease to accrue on this Note.

          12.  DEFAULTED INTEREST

          Except as otherwise specified with respect to the Notes, any Defaulted
Interest on any Note shall forthwith cease to be payable to the registered
Holder thereof on the relevant Regular Record Date or accrual date, as the case
may be, by virtue of having been such Holder, and such Defaulted Interest may be
paid by the Company as provided for in Section 4.10(b)(ii) of the Indenture.

          13.  DENOMINATIONS; TRANSFER; EXCHANGE

          The Notes are in registered form, without coupons, in denominations of
$1,000 of Principal Amount at Final Maturity and multiplies of $1,000.  A Holder
may transfer or convert 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 transfer or exchange any
Notes selected for redemption (except, in the case of a Note to be redeemed in
part, the portion of the Note not to be redeemed) or any Notes in respect of
which a Purchase Notice or Fundamental Change Purchase Notice has been given and
not withdrawn (except, in the case of a Note to be purchased in part, the
portion of the Note not to be purchased) or any Notes for a period of 15 days
before any selection of Notes to be redeemed.

          14.  PERSONS DEEMED OWNERS

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

          15.  UNCLAIMED MONEY OR PROPERTY

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent will pay the money back to the
Company at its request.  After that, Holders entitled to the money must look to
the Company for payment unless an abandoned property law designates another
person.

          16.  AMENDMENT; SUPPLEMENT; WAIVER

          Subject to certain exceptions, the Indenture or the Notes may be
amended or supplemented with the consent of the Holders of at least a majority
in principal amount of the outstanding Notes and any past default or compliance
with any provision relating to the Notes may be waived in a particular instance
with the consent of the Holders of a majority in principal amount of the
outstanding Notes.  Without the consent of any Securityholder, the Com-
<PAGE>

                                     -14-

pany and the Trustee may amend or supplement the Indenture or the Notes to cure
any ambiguity, defect or inconsistency, to provide for uncertificated Notes in
addition to or in place of certificated Notes, to create a Series and establish
its terms, to remove a Guarantor which, in accordance with the terms of the
Indenture, ceases to be liable in respect of its Guarantee, or to make any other
change, provided such action does not adversely affect the rights of any
Securityholder.

          17.  SUCCESSOR CORPORATION

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

          18.  TRUSTEE DEALINGS WITH THE COMPANY

          American Stock Transfer & Trust Company, the Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its affiliates, and may
otherwise deal with the Company or its affiliates, as if it were not Trustee.

          19.  NO RECOURSE AGAINST OTHERS

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

          20.  DISCHARGE OF INDENTURE

          The Indenture contains certain provisions pertaining to defeasance,
which provisions shall for all purposes have the same effect as if set forth
herein.

of authentication on the other side of this Note.

              [FORM OF NOTATION ON SECURITY RELATING TO GUARANTEE]

                                   GUARANTEE

          The undersigned (the "Guarantors") have unconditionally guaranteed,
jointly and severally (such guarantee by each Guarantor being referred to herein
as the "Guarantee") (i) the due and punctual payment of the principal of and
interest on the Notes, whether at maturity, by acceleration or otherwise, the
due and punctual payment of interest on the overdue principal and interest, if
any, on the Notes, to the extent lawful, and the due and punctual performance of
all other obligations of the Company to the Holders or the Trustee all in
accordance with the terms set forth in Article Nine of the Indenture and (ii) in
case of any extension of time of payment or renewal of any Notes or any of such
other obligations, that the same will be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, whether at
stated maturity, by acceleration or otherwise.

          No past, present or future stockholder, officer, director, employee or
incorporator, as such, of any of the Guarantors shall have any liability under
the Guarantee by reason of such person's status as stockholder, officer,
director, employee or incorporator.  Each holder of a Note by accepting a Note
waives and releases all such liability.  This waiver and release are part of the
consideration for the issuance of the Guarantees.

          Each holder of a Note by accepting a Note agrees that any Guarantor
named below shall have no further liability with respect to its Guarantee if
such Guarantor otherwise ceases to be liable in respect of its Guarantee in
accordance with the terms of the Indenture.

          The Guarantee shall not be valid or obligatory for any purpose until
the certificate of authentication on the Notes upon which the Guarantee is noted
shall have been executed by the Trustee under the Indenture by the manual
signature of one of its authorized officers.

*The comparable yield means the annual yield the Company would pay, as of the
Issue Date, on a fixed-rate cash-pay nonconvertible debt security with no
contingent payments but with terms and conditions otherwise comparable to those
of the Notes.  The schedule of projected payments is determined on the basis of
the comparable yield and an assumption of linear growth of the Company's stock
price and a constant dividend yield.  The comparable yield and the schedule of
projected payments are not determined for any purpose other than for the
determination of interest accruals and adjustment thereof in respect of the
Notes for United States federal income tax purposes.  The comparable yield and
the schedule of projected payments do not constitute a projection or
representation regarding the future stock price or the amounts payable on the
Notes.
