               GRANT OF PREMIUM PRICED NON-QUALIFIED STOCK OPTION
               --------------------------------------------------

         1. Grant of Option and Exercise Price. Subject to the terms and
conditions set forth herein and in the TB Wood's Corporation 1996 Stock-Based
Incentive Compensation Plan (the "Plan"), TB Wood's Corporation (the "Company")
hereby grants to _______________, (the "Optionee"), a stock option (the
"Option") to purchase up to _________ shares of Common Stock of the Company, par
value $.01 per share (the "Common Stock"), at an exercise price of $______ per
share (the "Exercise Price"). The Option is a non-qualified stock option.

         2. Vesting of Options. One-third of the shares of Common Stock subject
to the option shall vest on the first anniversary of the date of grant of the
Option (the "Grant Date"), an additional one-third of the shares of Common Stock
subject to the option shall vest on the second anniversary of the Grant Date,
and the final one-third of the shares of Common Stock subject to the option
shall vest on the third anniversary of the Grant Date.

         3. Time of Exercise. The Option may be exercised from time to time with
respect to shares for which the Option has vested but no later than the fifth
anniversary of the Grant Date. Upon the fifth anniversary of the Grant Date, the
Optionee's right to exercise the Option shall terminate absolutely.

         4. Payment for Shares of Common Stock. Upon exercise of an Option and
before delivery of the shares of Common Stock, full payment for shares of Common
Stock purchased upon the exercise of the Option shall be made in cash or,
subject to the approval of the Company committee administering the Plan (the
"Committee"), in whole or in part in shares of Common Stock valued at the fair
market value on the date of exercise.

         5. Manner of Exercise. The Option shall be exercised by giving written
notice of exercise to the Company (Attn: Chief Financial Officer) at the
Company's main office at 440 North Fifth Avenue, Chambersburg, Pennsylvania
17201-1778. Such notice of exercise must include a statement of preference as to
the manner in which payment to the Company shall be made. Such notice shall be
deemed to have been given when hand-delivered, telecopied or mailed, first-class
postage prepaid, and shall be irrevocable once given.

         6. Issuance of Certificates. As promptly as is reasonably practicable
after the exercise of the Option as determined by the Company, a certificate for
the shares of Common Stock issuable on the exercise of the Option shall be
delivered to Optionee or to his personal representative, heir or legatee.

         7. Nontransferability of Option. The Option may not be transferred or
assigned by Optionee otherwise than by will or the laws of descent and
distribution or be exercised other than by Optionee or, in the case of his
death, by his personal representative, heir or legatee.

         8. Taxes. Optionee shall be responsible to make appropriate provision
for all taxes required to be withheld in connection with any Option, the
exercise thereof and the transfer of the shares of Common Stock. Such
responsibility shall extend to all applicable federal, state, local or foreign
withholding taxes. In the case of exercise of the Option, the Company shall, at
the election of Optionee, have the right to retain the number of shares of
Common Stock whose aggregate fair market value equals the amount to be withheld
in satisfaction of the applicable withholding taxes.

         9. Termination of Employment. If the Optionee's employment by the
Company (or a subsidiary thereof) is terminated for any reason, all unvested
Options shall be forfeited and the Optionee shall have no further right to
exercise such Options. If the Optionee's employment by the Company (or a
subsidiary thereof) is terminated by reason of disability or retirement, all
unexercised, vested Options may be exercised pursuant to the terms of the Option
for a period of three months from the date of such termination of employment or
until the expiration of the term of the Option, whichever period is shorter;
provided, however, that if the Optionee's employment is terminated by death, all
unexercised, vested Options may be exercised pursuant to the terms of the Option
for a period of six months from the date of such termination of employment or

                                       50

until the expiration of the term of the Option, whichever period is shorter. If
the Optionee's employment by the Company (or a subsidiary thereof) is terminated
for any reason other than death, disability or retirement, all unexercised,
vested options shall terminate three months from the date of such termination of
employment.

         10. Rights Prior to Exercise. Neither Optionee nor his personal
representative, heir or legatee shall have any of the rights of a stockholder
with respect to any Common Stock until the date of the issuance to him or her of
a certificate for such Common Stock as provided herein.

         11. Amendments. The Committee may from time to time amend the terms of
this Option to the extent it deems appropriate to carry out the terms and
provisions of the Plan.

         12. Interpretation. The Committee shall have sole power to resolve any
dispute or disagreement arising out of this Agreement. The interpretation and
construction of any provision of this Option or the Plan made by the Committee
shall be final and conclusive and, insofar as possible, shall be consistent with
the requirements of a non-qualified stock option.

         13. Option Not to Affect Employment. The Option granted hereunder shall
not confer upon Optionee any right to continue in the employment of the Company
or any Subsidiary.

                  SECTION 3. (a) REGISTRAR, PAYING AGENT AND CONVERSION AGENT.

                  The following is hereby added to the Indenture in substitution
for the existing Section 2.5 thereof, with respect to the Debentures only:

         SECTION 2.5 REGISTRAR, PAYING AGENT AND CONVERSION AGENT.

                           The Company shall maintain an office or agency where
         Securities may be presented for registration of transfer or for
         exchange ("Registrar"), an office or agency where Securities may be
         presented for purchase or payment ("Paying Agent") and an office or
         agency where Securities may be presented for conversion into Common
         Stock ("Conversion Agent"). The Registrar shall keep a register of the
         Securities and of their transfer and exchange. The Company may have one
         or more co-registrars, one or more additional paying agents and one or
         more additional conversion agents. The term Paying Agent includes any
         additional paying agent. The term Conversion Agent includes any
         additional conversion agent.

                           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 cause to be furnished to the Trustee at least
         semiannually on August 21 and February 21 a listing of Holders dated
         within 15 days of the date on which the list is furnished 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.

                           The Company shall enter into an appropriate agency
         agreement with any Registrar, Paying Agent, Conversion Agent or
         co-registrar (if not the Trustee or an affiliate of the Trustee). The
         agreement shall implement the provisions of this Indenture that relate
         to such agent and the relevant Security. The Company shall notify the
         Trustee of the name and address of any such agent. If the Company fails
         to maintain a Registrar, Paying Agent or Conversion Agent, it shall
         direct the Trustee to act as such and the Trustee shall be entitled to
         compensation as agreed to in writing therefor. The Company or an
         Affiliate of the Company may act as Paying Agent, Registrar, Conversion
         Agent or co-registrar.

                           The Company initially appoints the Trustee as
         Registrar, Conversion Agent and Paying Agent in connection with the
         Securities.

                  (b)  REDEMPTION.

                  The following is hereby added to the Indenture, replacing the
existing Article 3 of the Indenture, with respect to the Debentures only:

                            REDEMPTION AND PURCHASES

                           SECTION 3.1 RIGHT TO REDEEM; NOTICES TO TRUSTEE.

                           The Company, at its option, may redeem the Securities
         in accordance with paragraph 3 of the Securities and the provisions of
         this Indenture. If the Company elects to redeem Securities pursuant to
         paragraph 3 of the Securities, it shall notify the Trustee in writing
         of the Redemption Date, the Principal of Securities to be redeemed and
         the Redemption Price.

                           The Company shall give the notice to the Trustee
         provided for in this Section 3.1 (i) in the case of any redemption of
         fewer than all of the Securities, at least 45 days before the
         Redemption Date and (ii) in the case of a redemption of all of the
         Securities, no later than the date that the Company is required to give
         notice to the Holders pursuant to Section 3.3, in each case unless a
         shorter notice shall be satisfactory to the Trustee.

                           SECTION 3.2 SELECTION OF SECURITIES TO BE REDEEMED.

                           If less than all the Securities held in definitive
         form are to be redeemed pursuant to Section 3.1, the Trustee shall
         select the definitive Securities to be redeemed pro rata or by lot or
         by another method the Trustee considers fair and appropriate (as long
         as such method is not prohibited by the rules of any quotation system
         or securities exchange on which the Securities are then quoted or
         listed). The Trustee shall make the selection at least 35 days, but not
         more than 60 days, before the Redemption Date from outstanding
         definitive Securities not previously called for redemption. The Trustee
         may select for redemption portions of the Principal of Securities that
         have denominations larger than $1,000. Securities and portions of them
         the Trustee selects shall be in Principals of $1,000 or an integral
         multiple of $1,000. Provisions of this Indenture that apply to
         definitive Securities called for redemption also apply to portions of
         definitive Securities called for redemption. The Trustee shall notify
         the Company promptly of the definitive Securities or portions of
         definitive Securities to be redeemed.

                           Any interest in a Security held in global form by and
         registered in the name of the Depositary or its nominee to be redeemed
         in whole or in part will be redeemed in accordance with the procedures
         of the Depositary.

                           If any Security selected for partial redemption is
         converted in part before termination of the conversion right with
         respect to the portion of the Security so selected, the converted
         portion of such Security shall be deemed to be (to the fullest extent
         possible) the portion selected for redemption. Securities which have
         been converted during a selection of Securities to be redeemed may be
         treated by the Trustee as outstanding for the purpose of such
         selection.

                           SECTION 3.3 NOTICE OF REDEMPTION.

                           At least 30 days but not more than 60 days before a
         Redemption Date, the Company shall mail a notice of redemption by
         first-class mail, postage prepaid, to each Holder of Securities to be
         redeemed.

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

                           (1) the Redemption Date;

                           (2) the Redemption Price;

                           (3) the Conversion Rate;

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

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

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

                           (7) that Securities called for redemption must be
         surrendered to the Paying Agent to collect the Redemption Price;

                           (8) if fewer than all the outstanding Securities are
         to be redeemed, the certificate number and Principals of the particular
         Securities to be redeemed;

         and

                           (10) the CUSIP number or numbers for the Securities.

                           The notice if mailed in the manner herein provided
         shall be conclusively presumed to have been duly given, whether or not
         the Holder receives such notice. In any case, failure to give such
         notice by mail or any defect in the notice to the Holder of any
         Security designated for redemption as a whole or in part shall not
         affect the validity of the proceedings for the redemption of any other
         Security.

                           At the Company's written request delivered to the
         Trustee at least 45 days before the Redemption Date, the Trustee shall
         give the notice of redemption in the Company's name and at the
         Company's expense.

                           SECTION 3.4 EFFECT OF NOTICE OF REDEMPTION.

                           Once notice of redemption is given, pursuant to
         Section 3.3, Securities called for redemption become due and payable on
         the Redemption Date and at the Redemption Price stated in the notice
         except for Securities which are converted in accordance with the terms
         of this Indenture.

                                       7
<PAGE>   8
                           Upon the later of the Redemption Date or the date
         such Securities are surrendered to the Paying Agent, such Securities
         shall be paid at the Redemption Price stated in the notice.

                           SECTION 3.5 DEPOSIT OF REDEMPTION PRICE.

                           Prior to 10:00 a.m. (local time at the place of
         payment) on the Redemption Date, the Company shall deposit with the
         Paying Agent (or if the Company or an Affiliate of the Company is the
         Paying Agent, shall segregate and hold in trust) money sufficient to
         pay the Redemption Price of all Securities to be redeemed on that date
         other than Securities or portions of Securities called for redemption
         which prior thereto have been delivered by the Company to the Trustee
         for cancellation or have been converted into Common Stock, and on or
         after the Redemption Date (unless the Company shall default in the
         payment of the Securities at the Redemption Price), Original Issue
         Discount on the Securities or portion of Securities called for
         redemption shall cease to accrue and such Securities shall cease after
         the close of business on the fourth Business Day immediately preceding
         the Redemption Date (except in the circumstances provided in Section
         3.7, immediately preceding the close of business on the Redemption
         Date) to be convertible into Common Stock and on and after the Business
         Day immediately preceding the Redemption Date, such Securities shall
         cease, except as provided in Section 8.5, to be entitled to any benefit
         or security under this Indenture, and the Holders thereof shall have no
         right in respect of such Securities except the right to receive the
         Redemption Price thereof and unpaid interest up to and including the
         Redemption Date. The Paying Agent shall as promptly as practicable
         return to the Company any money, with interest, if any, thereon, not
         required for that purpose because of conversion of Securities. If such
         money is then held by the Company in trust and is not required for such
         purpose it shall be discharged from such trust.

                           SECTION 3.6 SECURITIES REDEEMED IN PART.

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

                           SECTION 3.7 CONVERSION ARRANGEMENT ON CALL FOR
         REDEMPTION.

                           In connection with any redemption of Securities, the
         Company may arrange for the purchase and conversion into Common Stock
         of any Securities called for redemption by an agreement with one or
         more investment bankers or other purchasers to purchase such Securities
         by paying to the Paying Agent in trust for the Holders, prior to 10:00
         a.m. (local time at the place of payment) on the Redemption Date, an
         amount that, together with any amounts deposited with the Paying Agent
         by the Company for the redemption of the Securities, is not less than
         the Redemption Price up to and including the Redemption Date of such
         Securities. Notwithstanding anything to the contrary contained in this
         Article 3, the obligation of the Company to pay the Redemption Price of
         such Securities shall be deemed to be satisfied and discharged to the
         extent such amount is so paid by such purchasers. If such an agreement
         is entered into, any Securities not

                                       8
<PAGE>   9
         duly surrendered for conversion by the Holders thereof may, at the
         option of the Company, be deemed, to the fullest extent permitted
         by law, acquired by such purchasers from such Holders and
         (notwithstanding anything to the contrary contained in Article 11)
         surrendered by such purchasers for conversion, all immediately prior to
         the close of business on the Redemption Date, subject to payment of the
         above amount as aforesaid. The Paying Agent shall hold and pay to the
         Holders whose Securities are selected for redemption any such amount
         paid to it in the same manner as it would money deposited with it by
         the Company for the redemption of Securities. Without the Paying
         Agent's prior written consent, no arrangement between the Company and
         such purchasers for the purchase and conversion of any Securities shall
         increase or otherwise affect any of the powers, duties,
         responsibilities or obligations of the Paying Agent as set forth in
         this Indenture, and the Company agrees to indemnify the Paying Agent
         from, and hold it harmless against, any loss, liability or expense
         arising out of or in connection with any such arrangement for the
         purchase and conversion of any Securities between the Company and such
         purchasers, including the costs and expenses incurred by the Paying
         Agent in the defense of any claim or liability arising out of or in
         connection with the exercise or performance of any of its powers,
         duties, responsibilities or obligations under this Indenture.

                           SECTION 3.8 PURCHASE OF SECURITIES AT OPTION OF THE
         HOLDER.

                           (a) General. Securities shall be purchased by the
         Company pursuant to paragraph 4 of the Securities as of February 21,
         2006, February 21, 2011 and February 21, 2016 (each, a "Purchase
         Date"), at the purchase price specified therein (each, a "Purchase
         Price") at the option of the Holder thereof, upon:

                           (1) delivery to the Paying Agent by the Holder of a
         written notice of purchase (a "Purchase Notice") at any time from the
         opening of business on the date that is 20 Business Days prior to a
         Purchase Date until the close of business on such Purchase Date,
         stating:

                           (A) if certificated Securities have been issued, the
         certificate number of the Security which the Holder will deliver to be
         purchased (or, if the Security is not certificated, such other
         identification necessary to comply with appropriate DTC procedures);

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

                           (C) that such Security shall be purchased as of the
         Purchase Date pursuant to the terms and conditions specified in
         paragraph 4 of the Securities and the provisions of this 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

                                       9
<PAGE>   10
         Stock are not satisfied prior to or on the Purchase Date, as set forth
         in Section 3.8(d), whether such Holder elects (x) to withdraw such
         Purchase Notice as to some or all of the Securities to which such
         Purchase Notice relates (stating the Principal and certificate numbers
         of the Securities as to which such withdrawal shall relate), or (y) to
         receive Cash in respect of the entire Purchase Price for all Securities
         (or portions thereof) to which such Purchase Notice relates; and

                           (2) delivery of such Security 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 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 3.8 only if the Security so delivered to the Paying
         Agent shall conform in all respects to the description thereof in the
         related Purchase Notice.

                           If a Holder, in such Holder's Purchase Notice (and in
         any written notice of withdrawal of a portion of such Holder's
         Securities previously submitted for purchase pursuant to a Purchase
         Notice, the portion that remains subject to the Purchase Notice), fails
         to indicate such Holder's choice with respect to the election set forth
         in clause (D) of Section 3.8(a)(1), such Holder shall be deemed to have
         elected to receive Cash in respect of the entire Purchase Price for all
         Securities subject to such Purchase Notice in the circumstances set
         forth in such clause (D).

                           The Company shall purchase from the Holder thereof,
         pursuant to this Section 3.8, a portion of a Security if the Principal
         of such portion is $1,000 or an integral multiple of $1,000. Provisions
         of this Indenture that apply to the purchase of all of a Security also
         apply to the purchase of such portion of such Security.

                           Any purchase by the Company contemplated pursuant to
         the provisions of this Section 3.8 shall be consummated by the delivery
         of the consideration to be received by the Holder promptly following
         the later of the Purchase Date and the time of delivery of the
         Security.

                           Notwithstanding anything herein to the contrary, any
         Holder delivering to the Paying Agent the Purchase Notice contemplated
         by this Section 3.8(a) shall have the right at any time prior to the
         close of business on the Purchase Date to withdraw such Purchase Notice
         by delivery of a written notice of withdrawal to the Paying Agent in
         accordance with Section 3.10.

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

                           (b) Company's Right to Elect Manner of Payment of
         Purchase Price. The Company may elect with respect to any Purchase Date
         to pay the Purchase Price in respect of the Securities to be purchased
         pursuant to Section 3.8(a) as of such 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 3.8(c)
         and (d). The Company shall designate, in the Company Notice delivered
         pursuant to Section 3.8(e),

                                       10
<PAGE>   11
         whether the Company will purchase the Securities for Cash or Common
         Stock, or, if a combination thereof, the percentages of the Purchase
         Price of Securities in respect of which it will pay in Cash and/or
         Common Stock; provided that the Company will pay Cash for fractional
         interests in shares of Common Stock. For purposes of determining the
         existence of potential fractional interests, all Securities subject to
         purchase by the Company held by a Holder shall be considered together
         (no matter how many separate certificates are to be presented). Each
         Holder whose Securities are purchased pursuant to this Section 3.8
         shall receive the same percentage of Cash and/or Common Stock in
         payment of the Purchase Price for such Securities, except (i) as
         provided in Section 3.8(d) 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 Securities 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 Securities of such
         Holder or Holders for Cash. The Company may not change its election
         with respect to the consideration (or components or percentages of
         components thereof) to be paid once the Company has given its Company
         Notice to Holders except pursuant to this Section 3.8(b) or Section
         3.8(d).

                           At least two Business Days before the Company Notice
         Date (as defined in Section 3.8(c)), the Company shall deliver an
         Officers' Certificate to the Trustee specifying:

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

                           (ii) the information required by Section 3.8(e),

                           (iii) if the Company elects to pay the Purchase
         Price, or a specified percentage thereof, in Common Stock, that the
         conditions to such manner of payment set forth in Section 3.8(d) have
         been or will be complied with, and

                           (iv) whether the Company desires the Trustee to give
         the Company Notice required by Section 3.8(e).

                           (c) Purchase with Cash. At the option of the Company,
         the Purchase Price of Securities in respect of which a Purchase Notice
         pursuant to Section 3.8(a) has been given, or a specified percentage
         thereof, may be paid by the Company with Cash equal to the aggregate
         Purchase Price, or such specified percentage thereof, as the case may
         be, of such Securities. If the Company elects to purchase Securities
         with Cash, a Company Notice as provided in Section 3.8(e) shall be sent
         to Holders (and to beneficial owners as required by applicable law) not
         less than 20 Business Days prior to the Purchase Date (the "Company
         Notice Date").

                           (d) Payment by Issuance of Common Stock. At the
         option of the Company, the Purchase Price of Securities in respect of
         which a Purchase Notice pursuant to Section 3.8(a) 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 (i) the amount of Cash to which the Holders would
         have

                                       11
<PAGE>   12
         been entitled had the Company elected to pay all or such specified
         percentage, as the case may be, of the Purchase Price of such
         Securities in Cash by (ii) the Market Price of a share of Common Stock,
         subject to the next succeeding paragraph.

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

                           If the Company elects to purchase the Securities by
         the issuance of shares of Common Stock, a Company Notice as provided in
         Section 3.8(e) shall be sent to the Holders (and to beneficial owners
         as required by applicable law) not later than the Company Notice Date.

                           The Company's right to exercise its election to
         purchase the Securities pursuant to Section 3.8 through the issuance of
         shares of Common Stock shall be conditioned upon:

                           (i) the Company having given timely Company Notice of
         election to purchase all or a specified percentage of the Securities
         with Common Stock as provided herein;

                           (ii) the registration of the shares of Common Stock
         to be issued in respect of the payment of the specified percentage of
         the Purchase Price under the Securities Act; unless the shares of
         Common Stock so issued can be freely resold by the Holder (unless such
         Holder is the Company or an Affiliate of the Company) receiving such
         shares without registration under the Securities Act;

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

                           (iv) the receipt by the Trustee of an Officers'
         Certificate and an Opinion of Counsel each stating that (A) the terms
         of the issuance of the Common Stock are in conformity with this
         Indenture and (B) the shares of Common Stock to be issued by the
         Company in payment of the specified percentage of the Purchase Price in
         respect of Securities have been duly authorized and, when issued and
         delivered pursuant to the terms of this Indenture in payment of the
         specified percentage of the Purchase Price in respect of Securities,
         will be validly issued, fully paid and nonassessable, 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
         of Securities and the Sale Price of

                                       12
<PAGE>   13
         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.
         If such conditions are not satisfied with respect to a Holder or
         Holders prior to or on the Purchase Date and the Company elected to
         purchase the Securities to be purchased as of such Purchase Date
         pursuant to this Section 3.8 through the issuance of shares of Common
         Stock, the Company shall pay the entire Purchase Price in respect of
         such Securities of such Holder or Holders in Cash.

                           The "Market Price" means the average of the Sale
         Prices of the Common Stock for the five Trading Day period ending on
         the third Business Day prior to the applicable Purchase Date (if the
         third Business Day prior to the applicable Purchase Date is a Trading
         Day or, if it is not a Trading Day, the five Trading Days ending on the
         last Trading Day prior to the third Business Day), 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 Purchase Date, of any event described in
         Section 11.7, 11.8 or 11.9; subject, however, to the conditions set
         forth in Sections 11.10 and 11.11.

                             The "Sale Price" of the Common Stock on any date
         means the closing per share sale price (or if no closing sale price is
         reported the average of the bid and ask prices or, if more than one, in
         either case, the average of the average bid and average ask prices) on
         such date as reported on the New York Stock Exchange.

                           (e) Notice of Election. Company's notices of election
         to purchase with Cash or Common Stock, or any combination thereof,
         shall be sent to the Holders (and to beneficial owners as required by
         applicable law) in the manner provided in Section 10.2 at the time
         specified in Section 3.8(c) or (d), as applicable (each, a "Company
         Notice"). 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 a specified percentage thereof) with Common Stock,
         the Company Notice shall:

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

                           (2) set forth the method by which the Company is
         required to calculate the Market Price and state that because the
         Market Price of Common Stock will be determined prior to the Purchase
         Date, the 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 to be completed by a Holder and shall state:

                                       13
<PAGE>   14
                           (i) the Purchase Price and Conversion Rate;

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

                           (iii) that Securities as to which a Purchase Notice
         has been given may be converted only if the applicable Purchase Notice
         has been withdrawn in accordance with the terms of this Indenture;

                           (iv) that Securities must be surrendered to the
         Paying Agent to collect payment;

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

                           (vi) the procedures the Holder must follow under this
         Section 3.8;

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

                           (viii) the procedures for withdrawing a Purchase
         Notice (including, without limitation, for a conditional withdrawal
         pursuant to the terms of Section 3.8(a)(1)(D) or Section 3.10).

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

                           (f) Covenants of the Company. All shares of Common
         Stock delivered upon conversion or purchase of the Securities 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 use its best efforts to list or
         cause to have quoted all such shares of Common Stock on each United
         States over-the-counter or other domestic market on which the Common
         Stock is then quoted or national securities exchange on which the
         Common Stock is then listed. Upon determination of the actual number of
         shares of Common Stock to be delivered pursuant to this Section 3.8,
         the Company shall notify the securities exchange or quotation systems
         on which the Common Stock is then listed or quoted and disseminate the
         number of shares of Common Stock to be issued on the Company's website
         or through an alternative public medium.

                           (g) Procedure upon Purchase. On the Business Day
         following the Purchase Date, the Company shall deposit with the Paying
         Agent (A) Cash (in respect of a Cash purchase under Section 3.8(c) or
         for fractional interests, as applicable), or (B) shares of Common
         Stock, or a combination of (A) and (B), as applicable, sufficient to
         pay the aggregate Purchase Price in respect of the Securities to be
         purchased pursuant to this Section 3.8. As soon as practicable after
         the Purchase Date, the Company shall

                                       14
<PAGE>   15
         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 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. Subject to Section 3.8(d), no
         payment or adjustment will be made for dividends on the Common Stock
         the record date for which occurred on or prior to the Purchase Date.

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

                           SECTION 3.9 REDEMPTION AT OPTION OF THE HOLDER UPON A
         FUNDAMENTAL CHANGE.

                           (a) If a Fundamental Change shall occur at any time
         prior to February 21, 2021, each Holder of Securities shall have the
         right, at such Holder's option, to require the Company to redeem any or
         all of such Holder's Securities for Cash on the date that is 30 days
         after the date of the Company's notice of such Fundamental Change (the
         "Fundamental Change Redemption Date") (or if such date is not a
         Business Day, the next succeeding Business Day). The Securities will be
         redeemable in integral multiples of $1,000 of Principal. The Company
         shall redeem such Securities at a price (the "Fundamental Change
         Redemption Price") equal to the Issue Price plus accrued Original Issue
         Discount up to and including the Fundamental Change Redemption Date
         (or, if the Securities are converted to interest-bearing debentures
         following a Tax Event pursuant to Section 11.6 and paragraph 6(b) of
         the Securities, a price equal to the Restated Principal plus accrued
         interest from the date the Company exercised its right to convert the
         Securities up to and including the Fundamental Change Redemption Date).
         Payment for Securities surrendered for purchase (and not withdrawn)
         prior to the expiration of the 30-day period referenced in the first
         sentence of this subsection (a) shall be made promptly following the
         Fundamental Change Repurchase Date. No Securities may be redeemed at
         the option of the Holders as a result of 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 Redemption Price with
         respect to such Securities).

                           (b) The Company, or at its request (which must be
         received by the Trustee at least three Business Days prior to the date
         the Trustee is requested to give such notice as described below) the
         Trustee in the name of and at the expense of the Company, shall mail to
         the Trustee and all Holders of record of the Securities a notice (a
         "Fundamental Change Redemption Notice") of the occurrence of a
         Fundamental Change

                                       15
<PAGE>   16
         and of the redemption right arising as a result thereof on or before
         the tenth day after the occurrence of such Fundamental Change.

                           (c) For a Security to be so redeemed at the option of
         the Holder, the Paying Agent must receive such Security with the form
         entitled "Option to Elect Redemption Upon a Fundamental Change" on the
         reverse thereof duly completed, together with such Security duly
         endorsed for transfer, on or before the 30th day after the date of such
         notice (or if such 30th day is not a Business Day, the next succeeding
         Business Day).

                           SECTION 3.10 EFFECT OF PURCHASE NOTICE OR FUNDAMENTAL
         CHANGE REDEMPTION NOTICE.

                           Upon receipt by the Company of the Purchase Notice or
         Fundamental Change Redemption Notice specified in Section 3.8(a) or
         Section 3.9(b), as applicable, the Holder of the Security in respect of
         which such Purchase Notice or Fundamental Change Redemption Notice, as
         the case may be, was given shall (unless such Purchase Notice or
         Fundamental Change Redemption Notice is withdrawn as specified in the
         following two paragraphs) thereafter be entitled to receive solely the
         Purchase Price or Fundamental Change Redemption Price, as the case may
         be, with respect to such Security. Such Purchase Price or Fundamental
         Change Redemption Price shall be paid to such Holder promptly following
         the later of (x) the Purchase Date or the Fundamental Change Redemption
         Date, as the case may be, with respect to such Security (provided the
         conditions in Section 3.8(a) or Section 3.9(c), as applicable, have
         been satisfied) and (y) the time of delivery of such Security to the
         Paying Agent by the Holder thereof in the manner required by Section
         3.8(a) or Section 3.9(c), as applicable. Securities in respect of which
         a Purchase Notice or Fundamental Change Redemption 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 Redemption Notice, as the case
         may be), unless such Purchase Notice (or Fundamental Change Redemption
         Notice, as the case may be) has first been validly withdrawn as
         specified in the following two paragraphs.

                           A Purchase Notice or Fundamental Change Redemption
         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 Redemption Date, as the case may be, to which it
         relates specifying:

                           (1) if certificated Securities have been issued, the
         certificate number of the Security in respect of which such notice of
         withdrawal is being submitted,

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

                                       16
<PAGE>   17
                           (3) the Principal, if any, of such Security which
         remains subject to the original Purchase Notice or Fundamental Change
         Redemption Notice, as the case may be, and which has been or will be
         delivered for purchase or redemption by the Company.

                           A written notice of withdrawal of a Purchase Notice
         may be in the form of (i) a conditional withdrawal contained in a
         Purchase Notice pursuant to the terms of Section 3.8(a)(1)(D) or (ii) a
         conditional withdrawal containing the information set forth in Section
         3.8(a)(1)(D) and the preceding paragraph and contained in a written
         notice of withdrawal delivered to the Paying Agent as set forth in the
         preceding paragraph.

                           There shall be no purchase of any Securities pursuant
         to Section 3.8 (other than through the issuance of Common Stock in
         payment of the Purchase Price, including Cash in lieu of any fractional
         shares) or redemption pursuant to Section 3.9 if there has occurred
         (prior to, on or after, as the case may be, the giving, by the Holders
         of such Securities, of the required Purchase Notice or Fundamental
         Change Redemption 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 Redemption Price, as the case may be, with
         respect to such Securities).

                           SECTION 3.11 DEPOSIT OF PURCHASE PRICE OR FUNDAMENTAL
         CHANGE REDEMPTION PRICE.

                           On or before the Business Day following a Purchase
         Date or a Fundamental Change Redemption 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 as provided in Section 2.6) an
         amount of money and/or securities, if permitted hereunder, sufficient
         to pay the aggregate Purchase Price or Fundamental Change Redemption
         Price, as the case may be, of all the Securities or portions thereof
         which are to be purchased as of such Purchase Date or Fundamental
         Change Redemption Date, as the case may be.

                           SECTION 3.12 SECURITIES PURCHASED IN PART.

                           Any Security that is to be purchased or redeemed 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
         Security, without service charge, a new Security or Securities, of any
         authorized denomination as requested by such Holder in aggregate
         Principal equal to, and in exchange for, the portion of the Principal
         of the Security so surrendered which is not purchased or redeemed.

                           SECTION 3.13 COVENANT TO COMPLY WITH SECURITIES LAWS
         UPON PURCHASE OF SECURITIES.

                           In connection with any purchase or redemption of
         Securities under Section 3.8 or 3.9 hereof, the Company shall (i)
         comply with Rule 13e-4 (which term, as

                                       17
<PAGE>   18
         used herein, includes any successor provision thereto) under the
         Exchange Act, if applicable, (ii) file the related Schedule TO (or any
         successor schedule, form or report) under the Exchange Act, if
         applicable, and (iii) otherwise comply with all Federal and state
         securities laws so as to permit the rights and obligations under
         Section 3.8 and 3.9 to be exercised in the time and in the manner
         specified in Section 3.8 and 3.9.

                           SECTION 3.14 REPAYMENT TO THE COMPANY.

                           The Trustee and the Paying Agent shall return to the
         Company any cash or shares of Common Stock (in the case of the Purchase
         Price that remain unclaimed as provided in paragraph 12 of the
         Securities, together with interest or dividends, if any, thereon, held
         by them for the payment of a Purchase Price or Fundamental Change
         Redemption Price, as the case may be; provided, however, that to the
         extent that the aggregate amount of cash or shares of Common Stock
         deposited by the Company pursuant to Section 3.11 exceeds the aggregate
         Purchase Price or Fundamental Change Redemption Price, as the case may
         be, of the Securities or portions thereof which the Company is
         obligated to purchase as of the Purchase Date or Fundamental Change
         Redemption Date, as the case may be, then promptly after the Business
         Day following the Purchase Date or Fundamental Change Redemption Date,
         as the case may be, the Trustee and the Paying Agent shall return any
         such excess to the Company together with interest or dividends, if any,
         thereon.

                                       18
<PAGE>   19
                           SECTION 3.15 MODIFICATION TO FUNDAMENTAL CHANGE
         DEFINITIONS.

                  In the case of a reclassification, change, consolidation,
merger, combination, sale or conveyance to which Section 11.15 applies, in which
the Common Stock of the Company is changed or exchanged as a result into the
right to receive stock, securities or other property or assets (including Cash),
which includes shares of common stock of another person that are, or upon
issuance will be, traded on a United States national securities exchange or
approved for trading on an established automated over-the-counter trading market
in the United States and such shares of common stock constitute at the time such
change or exchange becomes effective in excess of 50% of the aggregate fair
market value of such stock, securities or other property or assets (including
Cash) into which the Common Stock of the Company is or is to be changed or
exchanged for (as determined by the Company, which determination shall be
conclusive and binding), then the person formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture (accompanied
by an Opinion of Counsel that such supplemental indenture complies with the
Trust Indenture Act as in force at the date of execution of such supplemental
indenture) modifying the provisions of this Indenture relating to the right of
holders of the Securities to cause the Company to repurchase the Securities in
the event of a Fundamental Change, including, without limitation, the applicable
provisions of this Article 3 and the definitions of Common Stock and Fundamental
Change, as appropriate, as determined in good faith by the Company (which
determination shall be conclusive and binding), to make such provisions apply to
such other person if different from the Company and the common stock issued
thereby (in lieu of the Company and the Common Stock of the Company).

                  (c)  EVENTS OF DEFAULT.

                  The following is hereby added to the Indenture in substitution
for the existing Section 6.1 and 6.2 thereof, with respect to the Debentures
only:

         SECTION 6.1 EVENTS OF DEFAULT.

                           An "Event of Default" occurs if:

                           (1) the Company defaults in the payment of the
         Principal Amount, Issue Price (or, if the Securities have been
         converted to interest-bearing Securities following a Tax Event pursuant
         to Section 11.6, the Restated Principal Amount), accrued Original Issue
         Discount (or, if the Securities have been converted to interest-bearing
         Securities following a Tax Event, accrued and unpaid interest), accrued
         Additional Interest, if any, Redemption Price, Purchase Price or a
         Fundamental Change Redemption Price on any Security when the same
         becomes due and payable at its Stated Maturity, upon redemption, upon
         declaration, when due for purchase by the Company or otherwise
         (provided that in the case of a default in the payment of Additional
         Interest, such default in payment of Additional Interest continues for
         a period of 30 days;

                           (2) the Company fails to comply with any of its
         agreements or covenants in the Securities or this Indenture (other than
         those referred to in clause (1)

                                       19
<PAGE>   20
         above) and such failure continues for 30 days after receipt by the
         Company of a Notice of Default;

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

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

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

         SECTION 6.2 ACCELERATION.

                           If an Event of Default (other than an Event of
         Default specified in Section 6.1(3) or (4) with respect to the Company)
         occurs and is continuing, the Trustee by notice to the Company, or the
         Holders of at least 25% in aggregate Principal Amount of the
         Securities, voting separately as a class, at the time outstanding by
         notice to the Company and the Trustee, may declare the Issue Price and
         accrued Original Issue Discount up to and including the date of
         declaration (and Additional Interest, if any) on all the Securities to
         be immediately due and payable. Upon such a declaration, such Issue
         Price and accrued Original Issue Discount shall become and be due and
         payable immediately; provided, however, that if an Event of Default
         specified in Section 6.1(2) occurs and is continuing, the Trustee by
         notice to the Company, or the Holders of at least 25% in

                                       20
<PAGE>   21
         aggregate Principal Amount of the Securities, together with all other
         holders of Securities of of each series of Securities issued under this
         Indenture, voting together as a class, at the time outstanding by
         notice to the Company and the Trustee, may declare the Issue Price and
         accrued Original Issue Discount up to and including the date of
         declaration (and Additional Interest, if any) on all the Securities to
         be immediately due and payable . If an Event of Default specified in
         Section 6.1(3) or (4) with respect to the Company occurs and is
         continuing, the Issue Price and accrued Original Issue Discount (and
         Additional Interest, if any) on all the Securities shall become and be
         immediately due and payable without any declaration or other act on the
         part of the Trustee or any Holders. The Holders of a majority in
         aggregate Principal Amount of the Securities at the time outstanding,
         by notice to the Company and the Trustee (and without notice to any
         other Holder), may rescind an acceleration and its consequences if the
         rescission would not conflict with any judgment or decree and if all
         existing Events of Default have been cured or waived except nonpayment
         of the Issue Price and accrued Original Issue Discount (and Additional
         Interest, if any) that have become due solely as a result of
         acceleration and if all amounts due to the Trustee under Section 7.7
         have been paid. No such rescission shall affect any subsequent or other
         Default or Event of Default or impair any consequent right.

                  (d)  AMENDMENTS.

                  The following is hereby added to the Indenture in substitution
for the existing Section 9.2 thereof, with respect to the Debentures only:

         SECTION 9.2 WITH CONSENT OF HOLDERS.

                           The Company and the Trustee, with the written consent
         of the Holders of at least a majority in aggregate Principal Amount of
         the Securities at the time outstanding, may amend this Indenture or the
         Securities. However, without the consent of each Holder affected, an
         amendment or supplement to this Indenture or the Securities may not:

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

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

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

                           (4) reduce the Redemption Price, Purchase Price or
         Fundamental Change Redemption Price of any Security;

                                       21
<PAGE>   22
                           (5) reduce the rate of, or make any change in the
         manner of paying, Additional Interest;

                           (6) make any Security payable in money or securities
         other than that stated in the Security; (7) make any change in Section
         6.4, Section 6.7 or this Section 9.2, except to increase any such
         percentage;

                           (8) make any change that adversely affects the right
         to convert any Security;

                           (9) make any change that adversely affects the right
         to require the Company to purchase the Securities, or the right to
         require the Company to redeem the Securities upon a Fundamental Change,
         in accordance with the terms thereof and this Indenture; or

                           (10) change any obligation of the Company to maintain
         an office or agency in the places and for the purposes specified in
         this Indenture.

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

                           After an amendment under this Section 9.2 becomes
         effective, the Company shall mail to each Holder a notice briefly
         describing the amendment.

                  (e)  CONVERSION.

                  The following is hereby added to the Indenture immediately
following Article 10, as a new Article 11, with respect to the Debentures only:

                                   ARTICLE 11

                                   CONVERSION

                           SECTION 11.1 CONVERSION PRIVILEGE.

                           A Holder of a Security may convert such Security for
         Common Stock at any time during the period stated in paragraph 6 of the
         Securities. The number of shares of Common Stock issuable upon
         conversion of a Security per $1,000 of Principal thereof (the
         "Conversion Rate") shall be that set forth in paragraph 6 in the
         Securities, subject to adjustment as herein set forth.

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

                                       22
<PAGE>   23
                           SECTION 11.2 CONVERSION PROCEDURE.

                           To convert a Security, a Holder must satisfy the
         requirements in paragraph 6 of the Securities. The date on which the
         Holder of Securities satisfies all those requirements is the conversion
         date (the "Conversion Date"). As soon as practicable after 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 11.3. The Person in whose name the
         certificate is registered shall be treated as the stockholder of record
         on and after the Conversion Date; provided, however, that no surrender
         of a Security on any date when the stock transfer books of the Company
         shall be closed shall be effective to constitute the Person or Persons
         entitled to receive the shares of Common Stock upon such conversion as
         the record holder or holders of such shares of Common Stock on such
         date, but such surrender shall be effective to constitute the Person or
         Persons entitled to receive such shares of Common Stock as the record
         holder or holders thereof for all purposes at the close of business on
         the next succeeding day on which such stock transfer books are open;
         such conversion shall be at the Conversion Rate in effect on the date
         that such Security shall have been surrendered for conversion, as if
         the stock transfer books of the Company had not been closed. Upon
         conversion of a Security, such Person shall no longer be a Holder of
         such Security.

                           No payment on the Securities or adjustment of the
         Conversion Rate will be made for dividends on or other distributions
         with respect to any Common Stock except as provided in this Article 11.
         On conversion of a Security, that portion of accrued Original Issue
         Discount attributable to the period from the Issue Date of the Security
         to the Conversion Date with respect to the converted Security 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 Security being converted pursuant to the
         provisions hereof.

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

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

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

                                       23
<PAGE>   24
                           SECTION 11.3 FRACTIONAL SHARES.

                           The Company will not issue a fractional share of
         Common Stock upon conversion of a Security. Instead the Company will
         deliver 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 last reported sale
         price (determined as set forth in the definition of Current Market
         Price) on the last Trading Day prior to the Conversion Date of a full
         share by the fractional amount and rounding the product to the nearest
         whole cent.

                           SECTION 11.4 TAXES ON CONVERSION.

                           If a Holder converts a Security, the Company shall
         pay any documentary, stamp or similar issue or transfer tax due on the
         issue of shares of Common Stock upon 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 will be due because the shares are to be issued in a name other
         than the Holder's name. Nothing herein shall preclude any tax
         withholding required by law or regulations.

                           SECTION 11.5 COMPANY TO PROVIDE STOCK.

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

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

                           The Company covenants that if any shares of Common
         Stock to be provided for the purpose of conversion of Securities
         hereunder require registration with or approval of any governmental
         authority under any federal or state law before such shares may be
         validly issued upon conversion, the Company will in good faith and as
         expeditiously as possible endeavor to secure such registration or
         approval, as the case may be.

                           The Company further covenants that if at any time the
         Common Stock shall be quoted on the Nasdaq National Market or any other
         automated quotation system or listed on the NYSE or any other national
         or regional securities exchange, the Company will, if permitted by the
         rules of such automated quotation system or exchange, list and keep
         listed, so long as the Common Stock shall be so listed on such
         automated quotation system or exchange, all shares of Common Stock
         issuable upon conversion of the Securities; provided, however, that if
         the rules of such automated quotation system or

                                       24
<PAGE>   25
         exchange permit the Company to defer the listing of such Common Stock
         until the first conversion of the Securities into Common Stock in
         accordance with the provisions of this Indenture, the Company covenants
         to list such Common Stock issuable upon conversion of the Securities in
         accordance with the requirements of such automated quotation system or
         exchange at such time.

                           SECTION 11.6 CONVERSION TO SEMIANNUAL COUPON UPON A
         TAX EVENT.

                           (a) If at any time after the date (the "Tax Event
         Date") of the occurrence of a Tax Event the Company exercises its
         option (the date of such exercise, (the "Option Exercise Date") to pay
         interest in lieu of Original Issue Discount, interest in lieu of future
         Original Issue Discount shall accrue at the rate of 4.0% per annum on a
         Principal per Security (the "Restated Principal") equal to the Issue
         Price plus Original Issue Discount accrued through the Option Exercise
         Date (as calculated by the Company and set forth in an Officer's
         Certificate delivered to the Trustee) and shall be payable semiannually
         on February 21 and August 21 of each year (each an "Interest Payment
         Date") to holders of record of the Securities at the close of business
         on the February 6 and August 6, respectively (each a "Regular Record
         Date"), immediately proceeding 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. Interest on any Security that is payable on any
         Interest Payment Date shall be paid to the Person in whose name that
         Security is registered at the close of business on the Regular Record
         Date.

                           (b) Within 15 days of the occurrence of a Tax Event,
         the Company shall mail a written notice of such Tax Event by first
         class mail to the Trustee and within 15 days of its exercise of such
         option the Company shall mail a written notice of the Option Exercise
         Date by first-class mail to the Trustee and the Holders of the
         Securities. From and after the Option Exercise Date, (i) the Company
         shall be obligated to pay at Stated Maturity, in lieu of the Principle
         Amount of a Security, the Restated Principal thereof and (ii) "Issue
         Price and accrued Original Issue Discount," "Issue Price plus Original
         Issue Discount" or similar words, as used herein, shall mean Restated
         Principal plus accrued and unpaid interest with respect to any
         Security. Securities 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
         Securities to semiannual coupon debentures.

                           (c) Interest on any Security 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 Security 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 Security 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 permanent Global Security, in
         global form, interest payable on any Interest Payment Date will be paid
         to the Depositary, with respect to that portion of such permanent
         Global Security, in global form, held for its account by Cede & Co. for
         the purpose of

                                       25
<PAGE>   26
         permitting such party to credit the interest received by it in respect
         of such permanent Security in global form to the accounts of the
         beneficial owners thereof.

                           (d) Except as otherwise specified with respect to the
         Security, any interest on any Security that is payable, but is not
         punctually paid or duly provided for, within 30 days following on any
         Interest 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 2 of the Securities),
         shall forthwith cease to be payable to the registered Holder thereof on
         the relevant Regular Record Date by virtue of having been such Holder,
         and such Defaulted Interest may be paid by the Company, at its election
         in each case, as provided in clause (1) or (2) below:

                                    (1) The Company may elect to make payment of
         any Defaulted Interest to the persons in whose names the Securities are
         registered at the close of business on a Special Record Date for the
         payment of such Defaulted Interest, which shall be fixed in the
         following manner. The Company shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Security
         and the date of the proposed payment (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 Securities at his address as it
         appears on the list of Securityholders maintained pursuant to Section
         2.5 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 Securities are
         registered at the close of business on such Special Record Date and
         shall no longer be payable pursuant to the following clause (2).

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

                           Subject to the foregoing provisions of this Section
         11.6 and Section 2.7, each Security delivered under this Indenture upon
         registration of transfer of or in

                                       26
<PAGE>   27
         exchange for or in lieu of any other Security shall carry the rights to
         interest accrued and unpaid, and to accrue, which were carried by such
         other Security.

                           (e) In the event that the Company exercises its
         option following a Tax Event, any Security or portion thereof
         surrendered for conversion during the period from the close of business
         on the Regular Record Date to the opening of business on the
         immediately following Interest Payment Date (unless such Security or
         portion thereof being converted shall have been called for redemption
         on a date in such period) must be accompanied by a payment, in funds
         acceptable to the Company, of an amount of interest otherwise payable
         on such Interest Payment Date on the amount of principal being
         converted.

                           Interest on any Security that is payable on any
         Interest Payment Date shall be paid to the Person in whose name that
         Security is registered at the close of business on the Regular Record
         Date.

                           SECTION 11.7 ADJUSTMENT FOR CHANGE IN CAPITAL STOCK.

                           In case the Company shall (i) pay a dividend, or make
         a distribution, in shares of its Common Stock, on its 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 Security thereafter
         surrendered for conversion shall be entitled to receive the number of
         shares of Common Stock which such Holder would have owned or have been
         entitled to receive after the occurrence of any of the events described
         above had such Security been converted immediately prior to the
         occurrence 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 as distribution had not been declared. An
         adjustment made pursuant to this Section 11.7 shall become effective
         immediately after the record date in the case of a dividend and still
         shall become effective immediately after the effective date in the case
         of a subdivision or combination.

                           SECTION 11.8 ADJUSTMENT FOR RIGHTS ISSUE.

                           In case the Company shall issue rights or warrants to
         all holders of its Common Stock entitling them (for a period expiring
         within 45 days after the record date mentioned below) to subscribe for
         or purchase Common Stock at a price per share less than the Current
         Market 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 issuance of such rights or warrants by a fraction of which the
         numerator shall be the number of shares of Common Stock outstanding on
         the date of issuance of such rights or warrants plus the number of
         additional shares of Common Stock offered to holders of Common Stock
         for subscription or purchase, and of which the denominator shall be the
         number of shares of Common Stock outstanding on the date of

                                       27
<PAGE>   28
         issuance of such rights or warrants plus the number of shares of Common
         Stock which the aggregate offering price of the total number of shares
         so offered would purchase at such Current Market 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 Common Stock are not delivered after the
         expiration of such rights or warrants, the Conversion Rate shall be
         readjusted to the Conversion Rate which would then be in effect had the
         adjustments made upon the issuance of such rights or warrants been made
         on the basis of delivery of only the number of shares of Common Stock
         actually delivered. 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 Common Stock at less
         than such Current Market Price of such Common Stock, and in determining
         the aggregate offering price of such shares of Common Stock, there
         shall be taken into account any consideration received by the Company
         for such rights or warrants, the value of such consideration, if other
         than Cash, to be determined by the Board of Directors.

                           SECTION 11.9 ADJUSTMENT FOR OTHER DISTRIBUTIONS.

                           (a) In case the Company shall distribute to all
         holders of its Common 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 Common Stock), of evidences of indebtedness of
         the Company or of assets (other than cash) or rights or warrants to
         subscribe for or purchase any of its securities (excluding those
         referred to in Section 11.8 hereof) (any of the foregoing hereinafter
         in this Section 11.9(a) 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 Current Market Price per share of the
         Common Stock on the record date mentioned below, and the denominator
         shall be the Current 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 of the Company, whose
         determination shall be conclusive, and described in a certificate filed
         with the Trustee) of the Distributed Securities so distributed
         applicable to one share of Common 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 that the then fair market value (as so
         determined) of the portion of the Distributed Securities so distributed
         applicable to one share of Common Stock is equal to or greater than the
         Current Market Price of the Common Stock on the record date, in lieu of
         the foregoing adjustment, adequate provision shall be made so that each
         Holder shall have the right to receive upon conversion the amount of
         Distributed Securities such Holder would have received had such Holder
         converted each Security immediately prior to such record date. In the
         event that such distribution is not so paid or made, the Conversion
         Rate shall again be adjusted

                                       28
<PAGE>   29
         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 11.9(a) by reference to the actual or when issued trading
         market for any securities, it must in doing so consider the prices in
         such market over the same period used in computing the Current Market
         Price of the Common Stock.

                           Notwithstanding the foregoing provisions of this
         Section 11.9(a), no adjustment shall be made thereunder for any
         distribution of Distributed Securities if the Company makes proper
         provision so that each Holder of a Security who converts such Security
         (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 Security 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 Security 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 Security.

                           (b) In case the Company shall, by dividend or
         otherwise, distribute to all holders of its Common Stock Cash
         (excluding any quarterly Cash dividend on the Common Stock to the
         extent the aggregate Cash dividend per share of Common Stock in any
         fiscal quarter does not exceed the greater of (A) the amount per share
         of Common Stock of the next preceding quarterly Cash dividend on the
         Common Stock to the extent such preceding quarterly dividend did not
         require any adjustment of the Conversion Rate pursuant to this Section
         11.9(b) (as adjusted to reflect subdivisions or combinations of the
         Common Stock), and (B) 3.75% of the average of the last reported sales
         price of the Common Stock (determined as provided in the definition of
         Current Market Price) during the ten Trading Days immediately prior to
         the date of declaration of such dividend and (), then, in such case,
         unless the Company elects to reserve such Cash for distribution to the
         holders of the Securities upon the conversion of the Securities so that
         any such holder converting Securities will receive upon such conversion
         in addition to the shares of Common Stock to which such holder is
         entitled, the amount of Cash which such holder would have received if
         such holder had, immediately prior to the record date for such
         distribution of Cash, converted its Securities for Common Stock, 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 Current Market Price of the Common Stock and
         the denominator shall be the Current Market Price of the Common Stock
         on the record date less the amount of Cash so distributed (and not
         excluded as provided above) applicable to one share of Common Stock,
         such increase to be effective immediately prior to the opening of
         business on the day following the record date; provided, however, that
         in the event that the portion of the Cash so distributed applicable to
         one share of Common Stock is equal to or greater than the Current
         Market Price of the Common Stock on the record date, in lieu of the
         foregoing adjustment, adequate provision shall be made so that each
         Holder shall have the right to receive upon conversion the amount of
         Cash

                                       29
<PAGE>   30
         such Holder would have received had such Holder converted each Security
         on the 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 11.9(b) 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 11.9(b) 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.

                           (c) In case a tender or exchange offer made by the
         Company or any Subsidiary of the Company for all or any portion of the
         Common Stock shall expire and such tender or exchange offer shall
         involve the payment by the Company or such Subsidiary of consideration
         per share of Common Stock having a fair market value (as determined by
         the Board of Directors, whose determination shall be conclusive, and
         described in a resolution of such Board of Directors at the last time
         (the "Expiration Time") tenders or exchanges may be made pursuant to
         such tender or exchange offer (as it shall have been amended)) that
         exceeds the Current Market Price of the Common Stock on the Trading Day
         next succeeding the Expiration Time, 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 sum
         of (x) the fair market value (determined as aforesaid) of the aggregate
         consideration payable to holders of Common Stock based on the
         acceptance (up to any maximum specified in the terms of the tender or
         exchange offer) of all shares of Common Stock validly tendered or
         exchanged and not withdrawn as of the Expiration Time (the shares
         deemed so accepted up to any such maximum, being referred to as the
         "Purchased Shares") and (y) the product of the number of shares of
         Common Stock outstanding (less any Purchased Shares) on the Expiration
         Time and the Current Market Price of the Common Stock on the Trading
         Day next succeeding the Expiration Time, and the denominator shall be
         the number of shares of Common Stock outstanding (including any
         tendered or exchanged shares) on the Expiration Time multiplied by the
         Current Market Price of the Common Stock on the Trading Day next
         succeeding the Expiration Time, such increase to become effective
         immediately prior to the opening of business on the day following the
         Expiration Time. In the event that the Company is obligated to purchase
         shares pursuant to any such tender or exchange offer, but the Company
         is permanently prevented by applicable law from effecting any such
         purchases or all such purchases are rescinded, the Conversion Rate
         shall again be adjusted to be the Conversion Rate which would then be
         effect if such tender or exchange offer had not been made.

                           (d) In case of a tender or exchange offer by a Person
         other than the Company or any Subsidiary for an amount which increases
         the offeror's ownership of Common Stock to more than 25% of the Common
         Stock outstanding and shall involve the payment by such Person of
         consideration per share of Common Stock having a fair market value (as
         determined by the Board of Directors, whose determination shall be
         conclusive, and described in a resolution of the Board of Directors at
         the last time (the

                                       30
<PAGE>   31
         "Tender Expiration Time") tenders or exchanges may be made pursuant to
         such tender or exchange offer (as it shall have been amended)) at the
         Tender Expiration Time that exceeds the Current Market Price of the
         Common Stock on the Trading Day next succeeding the Tender Expiration
         Time, and in which, as of the Tender Expiration Time the Board of
         Directors is not recommending rejection of the offer, 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 Tender Expiration Time by a fraction of which
         the numerator shall be the sum of (x) the fair market value (determined
         as aforesaid) of the aggregate consideration payable to holders of
         Common Stock based on the acceptance (up to an maximum specified in the
         terms of the tender or exchanged offer) of all shares of Common Stock
         validly tendered or exchanged and not withdrawn as of the Tender
         Expiration Time (the shares deemed so accepted, up to any such maximum,
         being referred to as the "Tender Purchased Shares") and (y) the product
         of the number of shares of Common Stock outstanding (less any Tender
         Purchased Shares) on the Tender Expiration Time and the Current Market
         Price of the Common Stock on the Trading Day next succeeding the Tender
         Expiration Time and the denominator shall be the number of shares of
         Common Stock outstanding (including any tendered or exchanged shares)
         on the Tender Expiration Time multiplied by the Current Market Price of
         the Common Stock on the Trading Day next succeeding the Tender
         Expiration Time, such increase to become effective immediately prior to
         the opening of business on the day following the Tender Expiration
         Time. In the event that such Person is obligated to purchase shares
         pursuant to any such tender or exchange offer, but such Person is
         permanently prevented by applicable law from effecting any such
         purchases or all such purchases are rescinded, the Conversion Rate
         shall again be adjusted to be the Conversion Rate which would then be
         in effect if such tender or exchange offer had not been made.
         Notwithstanding the foregoing, the adjustment described in this Section
         11.9(d) shall not be made if, as of the Tender Expiration Time, the
         offering documents with respect to such offer disclose a plan or
         intention to cause the Company to engage in any transaction described
         in Article 5.

                           SECTION 11.10 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. Any adjustments that are made shall be
         carried forward and taken into account any subsequent adjustment.

                           All calculations under this Article 11 shall be made
         to the nearest cent or to the nearest 1/10,000th of a share, as the
         case may be.

                           SECTION 11.11 WHEN NO ADJUSTMENT REQUIRED.

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

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

                                       31
<PAGE>   32
                           To the extent the Securities become convertible into
         Cash, assets, property or securities (other than capital stock of the
         Company), no adjustment need be made thereafter as to the cash, assets,
         property or such securities. Interest will not accrue on the Cash.

                           SECTION 11.12 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 the Trustee nor any Conversion Agent
         shall be under any duty or responsibility with respect to any such
         certificate except to exhibit the same to any Holder desiring
         inspection thereof.

                           SECTION 11.13 VOLUNTARY INCREASE.

                           The Company may make such increases in the Conversion
         Rate, in addition to those required by Sections 11.7, 11.8 and 11.9, as
         the Board of Directors considers to be advisable to avoid or diminish
         any income tax to holders of Common Stock or rights to purchase Common
         Stock resulting from any dividend or distribution of stock (or rights
         to acquire stock) or from any event treated as such for income tax
         purposes. To the extent permitted by applicable law, the Company 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. The Company shall mail such notice at least seven days before
         the date the increased Conversion Rate takes effect. The notice shall
         state the increased Conversion Rate and the period it will be in
         effect.

                           SECTION 11.14 NOTICE OF CERTAIN TRANSACTIONS.

                           If:

                           (1) the Company makes any distribution or dividend
         that would require an adjustment in the Conversion Rate pursuant to
         Section 11.7, 11.8 or 11.9; or

                           (2) the Company takes any action that would require a
         supplemental indenture pursuant to Section 11.15; or

                           (3) there is a liquidation, dissolution or winding-up
         of the Company;

         then the Company shall mail to Holders and file with the Trustee and
         the Conversion Agent a notice stating the proposed record date for a
         dividend or distribution or the proposed effective date of a
         subdivision, combination, reclassification, consolidation, merger,
         sale, transfer, dissolution, liquidation or winding up. The Company
         shall file and

                                       32
<PAGE>   33
         mail the notice at least 15 days before such date. Failure to file or
         mail the notice or any defect in it shall not affect the validity of
         the transaction.

                           SECTION 11.15 EFFECT OF RECLASSIFICATION,
         CONSOLIDATION, MERGER OR SALE.

                           If any of the following events occur, namely (i) any
         reclassification or change of outstanding shares of Common Stock (other
         than a change in par value, or from par value to no par value, or from
         no par value to par value, or as a result of a subdivision or
         combination), (ii) any consolidation, merger or combination of the
         Company with another corporation as a result of which holders of Common
         Stock shall be entitled to receive stock, securities or other property
         or assets (including Cash) with respect to or in exchange for such
         Common Stock, or (iii) any sale or conveyance of the properties and
         assets of the Company as, or substantially as, an entirety to any other
         corporation as a result of which holders of Common Stock shall be
         entitled to receive stock, securities or other property or assets
         (including Cash) with respect to or in exchange for such Common Stock,
         then the Company or the successor or purchasing corporation, as the
         case may be, shall execute with the Trustee a supplemental indenture,
         providing that each Security shall be convertible into the kind and
         amount of shares of stock and other securities or property or assets
         (including Cash) receivable upon such reclassification, change,
         consolidation, merger, combination, sale or conveyance by a holder of a
         number of shares of Common Stock issuable upon conversion of such
         Securities 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 Article.

                           The Company shall cause notice of the execution of
         such supplemental indenture to be mailed to each Holder of Securities,
         at such Holder's address appearing on the Security register provided
         for in Section 2.3 of this Indenture.

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

                           If this Section applies, neither Section 11.7, 11.8
         nor 11.9 applies.

                           SECTION 11.16 COMPANY DETERMINATION FINAL.

                           Any determination that the Company or the Board of
         Directors must make pursuant to Section 11.3, 11.7, 11.8, 11.9, 11.10,
         11.11, 11.15 or 11.18 is conclusive.

                           SECTION 11.17 TRUSTEE'S ADJUSTMENT DISCLAIMER.

                           The Trustee has no duty to determine when an
         adjustment under this Article 11 should be made, how it should be made
         or what it should be. The Trustee has no duty to determine whether a
         supplemental indenture under Section 11.15 need be entered into or
         whether any provisions of any supplemental indenture are correct. The
         Trustee shall not be accountable for and makes no representation as to
         the validity or

                                       33
<PAGE>   34
         value of any securities or assets issued upon conversion of Securities.
         The Trustee shall not be responsible for the Company's failure to
         comply with this Article 11, and shall not be deemed to have knowledge
         of any adjustment unless and until it shall have received a notice of
         adjustment pursuant to Section 11.12. Each Conversion Agent shall have
         the same protection under this Section 11.17 as the Trustee.

                           SECTION 11.18 SIMULTANEOUS ADJUSTMENTS.

                           In the event that this Article 11 requires
         adjustments to the Conversion Rate under more than one of Sections
         11.7, 11.8, 11.9(a) or 11.9(b), 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 11.9(a), second, the provisions of Section
         11.9(b), third the provisions of Section 11.7 and, fourth, the
         provisions of Section 11.8.

                           SECTION 11.19 SUCCESSIVE ADJUSTMENTS.

                           After an adjustment to the Conversion Rate under this
         Article 11, any subsequent event requiring an adjustment under this
         Article 11 shall cause an adjustment to the Conversion Rate as so
         adjusted.

                           SECTION 11.20 RIGHTS ISSUED IN RESPECT OF COMMON
         STOCK ISSUED UPON CONVERSION.

                           Notwithstanding any other provision hereof, in the
         event that the Company implements a stockholders' rights plan, such
         rights plan shall provide that upon conversion of the Securities the
         Holders will receive, in addition to the Common Stock issuable upon
         such conversion, such rights whether or not such rights have separated
         from the Common Stock at the time of such conversion. In the event that
         provision is made that a Holder of Securities will receive such rights
         upon conversion, whether or not the rights have separated from the
         Common Stock at the time of such conversion, no adjustment shall be
         made to the Conversion Rate pursuant to this Article 11 as a result of
         such rights distribution.

                           Rights or warrants distributed by the Company to all
         holders of Common Stock entitling the holders thereof to subscribe for
         or purchase shares of the Company's capital stock (either initially or
         under certain circumstances), which rights or warrants, until the
         occurrence of a specified event or events ("Trigger Event"):

                           (i) are deemed to be transferred with such shares of
         Common Stock,

                           (ii) are not exercisable, and

                           (iii) are also issued in respect of future issuances
         of Common Stock,

         shall not be deemed distributed for purposes of Section 11.9(a) until
         the occurrence of the earliest Trigger Event. In addition, in the event
         of any distribution of rights or warrants, or any Trigger Event with
         respect thereto, that shall have resulted in an adjustment to the

                                       34
<PAGE>   35
         Conversion Rate under Section 11.9(a), (1) in the case of any such
         rights or warrants which shall all have been redeemed or repurchased
         without exercise by any holders thereof, the Conversion Rate shall be
         readjusted upon such final redemption or repurchase to give effect to
         such distribution or Trigger Event, as the case may be, as though it
         were a cash distribution, equal to the per share redemption or
         repurchase price received by a holder of Common Stock with respect to
         such rights or warrants (assuming such holder had retained such rights
         or warrants), made to all holders of Common Stock as of the date of
         such redemption or repurchase, and (2) in the case of any such rights
         or warrants all of which shall have expired without exercise by any
         holder thereof, the Conversion Rate shall be readjusted as if such
         issuance had not occurred.

                           SECTION 11.21 GENERAL CONSIDERATIONS.

                           Whenever successive adjustments to the Conversion
         Rate are called for pursuant to this Article 11, such adjustments shall
         be made to the Current Market Price or the conversion rate adjustment
         provisions of Sections 11.7, 11.8, 11.9 and 11.18 as may be necessary
         or appropriate to effectuate the intent of this Article 11 and to avoid
         unjust or inequitable results as determined in good faith by the Board
         of Directors.
