All other terms used in this Supplemental Indenture that are defined in the Indenture or the Trust Indenture Act, either directly or by reference therein (except as herein otherwise expressly provided or unless the context of this Supplemental Indenture otherwise requires), have the respective meanings assigned to such terms in the Indenture or the Trust Indenture Act, as the case may be, as in force at the date of this Supplemental Indenture as originally executed. "Applicable Price" shall mean (i) in the event of a Fundamental Change in which the holders of the Company's Common Stock receive only cash, the amount of cash received by the holder of one share of Common Stock and (ii) in the event of any other Fundamental Change, the arithmetic average of the Closing Price for the Company's Common Stock (determined as set forth in Section 502(h)) during the ten Trading Days (as defined in Section 502(h)) prior to the record date for the determination of the holders of Common Stock entitled to receive cash, securities, property or other assets in connection with such Fundamental Change, or, if there is no such record date, the date upon which the holders of the Common Stock shall have the right to receive such cash, securities, property or other assets in connection with the Fundamental Change. "Closing Price" shall have the meaning specified in Section 502(h)(1). "Conversion Price" has the meaning specified in Section 501 of this Supplemental Indenture.

"Redemption Date", when used with respect to any Note to be redeemed, means the date fixed for such redemption by or pursuant to this Supplemental Indenture. "Redemption Price", when used with respect to any Note to be redeemed, means the price at which it is to be redeemed pursuant to this Supplemental Indenture. -3- "Repurchase Date" shall have the meaning specified in Section 601. "Reference Market Price" shall initially mean $18.1667 and in the event of any adjustment to the Conversion Price pursuant to Sections 502(a), (b), (c), (d), (e), (f) or (g), the Reference Market Price shall also be adjusted so that the ratio of the Reference Market Price to the Conversion Price after giving effect to any such adjustment shall always be the same as the ratio of $18.1667 to the initial Conversion Price specified in the form of Note included herein (without regard to any adjustment thereto). "Rights Agreement" means that certain Preferred Shares Rights Agreement, dated as of August 3, 1988, between the Company and Bank of America National Trust & Savings Association, as amended from time to time.

"Trigger Event" shall have the meaning specified in Section 502(d). The definitions of other terms are specified in Articles Five and Six. ARTICLE THREE CERTAIN COVENANTS The following covenant shall be applicable to the Company for so long as any of the Notes are outstanding. Section 301 Registration and Listing. The Company (i) will effect all registrations with, and obtain all approvals by, all governmental authorities that may be necessary under any United States Federal or state law (including the Securities Act, the Exchange Act and state securities and Blue Sky laws) before the shares of Common Stock issuable upon conversion of Notes may be lawfully issued and delivered, and thereafter publicly traded, and qualified or listed as contemplated by clause (ii); and (ii) will list the shares of Common Stock required to be issued and delivered upon conversion of the Notes prior to such issuance or delivery on the Nasdaq National Market or such other exchange or automated quotation as the Common Stock is then listed at such date of conversion. The provisions of Section 1008 of the Indenture shall not apply to this Section 301. -4- ARTICLE FOUR REDEMPTION OF NOTES Section 401 Right of Redemption. The Notes will not be subject to redemption prior to August 1, 1999 and will be redeemable on and after such date at the option of the Company, in whole or in part, upon not less than 15 nor more than 60 days' notice to the Holders, at the Redemption Prices (expressed as a percentage of principal amount) set forth below; provided, however, that the Notes will not be redeemable following August 1, 1999, and before August 1, 2001, unless the Closing Price of the Company's Common Stock is at least 125% of the Conversion Price for at least 20 Trading Days within a period of 30 consecutive Trading Days ending within five Trading Days prior to the notice of redemption. The Redemption Price (expressed as a percentage of principal amount) is as follows for the 12-month periods beginning on August 1 of the following years:
YEAR REDEMPTION PRICE - ---- ---------------- 1999.............................................. 105% 2000.............................................. 104% 2001.............................................. 103% 2002.............................................. 102% 2003.............................................. 101%
and 100% at August 1, 2004, in each case together with accrued and unpaid interest to, but excluding, the Redemption Date; provided, however, that interest installments whose Stated Maturity is on such Redemption Date will be payable to the Holders of such Notes, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. The Notes are not subject to redemption through operation of any sinking fund. Section 402 Conversion Arrangement on Call for Redemption. In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes by an agreement with one or more investment bankers or other purchasers to purchase such Notes by paying to the Trustee in trust for the Holders, on or before the date fixed for redemption, an amount not less than the applicable Redemption Price, together with interest accrued to (but excluding) the date fixed for redemption, of such Notes. Notwithstanding anything to the contrary contained herein, the obligation of the Company to pay the Redemption Price of such Notes, together with interest accrued to (but excluding) the Redemption Date, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, a copy of which will be filed with the Trustee prior to the Redemption Date, any Notes not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be -5- deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained herein) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the Redemption Date (and the right to convert any such Notes shall be extended through such time), subject to payment of the above amount as aforesaid. At the direction of the Company, the Trustee shall hold and dispose of any such amount paid to it in the same manner as it would monies deposited with it by the Company for the redemption of Notes. Without the Trustee's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Notes shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Notes between the Company and such purchasers to which the Trustee has not consented in writing, including the costs and expenses, including reasonable legal fees, incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture. ARTICLE FIVE CONVERSION OF NOTES Section 501 Conversion Privilege and Conversion Price Subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Note may be converted into fully paid and nonassessable shares of Common Stock of the Company at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall commence on August 1, 1997 and expire at the close of business on August 1, 2004, subject, in the case of the conversion of any Global Security, to any applicable book-entry procedures of the Depositary therefor. In case a Note is called for redemption at the election of the Company, such conversion right in respect of the Note shall expire at the close of business on the Business Day next preceding the Redemption Date. A Note in respect of which a Holder is exercising its option to require redemption upon a Fundamental Change may be converted only if such Holder withdraws its election to exercise its option in accordance with Article Six of this Supplemental Indenture. The initial Conversion Price of the Notes is $46.325 per share of Common Stock, and shall be adjusted in certain instances as provided in this Article Five. Section 502 Adjustment of Conversion Price. The Conversion Price shall be subject to adjustment from time to time as follows: -6- (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to become effective immediately after the opening of business on the day following the date fixed for such determination. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this Section 502(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. (b) In case the Company shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within 45 days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price (as defined below) on the date fixed for determination of stockholders entitled to receive such rights or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights and warrants plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at such Current Market Price, and of which the denominator shall be the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights and warrants plus the total number of additional shares of Common Stock offered for subscription or purchase. Such adjustment shall be successively made whenever any such rights and warrants are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of 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 Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received 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. -7- (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section 502(a) applies) or evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to in Section 502(b), and excluding any dividend or distribution (x) paid exclusively in cash or (y) referred to in Section 502(a) (any of the foregoing hereinafter in this Section 502(d) called the "Distribution Securities")), then, in each such case (unless the Company elects to reserve such Distribution Securities for distribution to the Holders upon the conversion of the Notes so that any such Holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such Holder is entitled, the amount and kind of such Distribution Securities which such Holder would have received if such Holder had converted its Notes into Common Stock immediately prior to the Distribution Record Date (as defined in Section 502(h) for such distribution of the Distribution Securities)), the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect on the Distribution Record Date with respect to such distribution by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock on such Distribution Record Date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) on the Distribution Record Date of the portion of the Securities so distributed applicable to one share of Common Stock and the denominator shall be the Current Market Price per share of the Common Stock, such reduction to become effective immediately prior to the opening of business on the day following such Distribution Record Date; provided, however, that in the event the then fair market value (as so determined) of the portion of the Distribution 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 Distribution 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 Securities such Holder would have received had such Holder converted each Note on the Distribution Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 502(d) 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. -8- Each share of Common Stock issued upon conversion of Notes shall be entitled to receive the appropriate number of Rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as provided by and subject to the terms of the Rights Agreement as in effect at the time of such conversion. If the Rights are separated from the Common Stock in accordance with the provisions of the Rights Agreement such that the Holders would thereafter not be entitled to receive any such Rights in respect to the Common Stock issuable upon conversion of such Notes, the Conversion Price will be adjusted as provided in this Section 502(d) on the separation date; provided that if such Rights expire, terminate or are redeemed by the Company, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such separation had not occurred. In lieu of any such adjustment, the Company may amend the Rights Agreement to provide that upon conversion of the Notes the Holders will receive, in addition to the Common Stock issuable upon such conversion, the Rights which would have attached to such shares of Common Stock if the Rights had not become separated from the Common Stock pursuant to the provisions of the Rights Agreement. 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 be deemed not to have been distributed for purposes of this Section 502 (and no adjustment to the Conversion Price under this Section 502 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Price shall be made under this Section 502(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Supplemental Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under this Section 502 was made, (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights and warrants had not been issued. -9- For purposes of this Section 502(d) and Sections 502(a) and (b), any dividend or distribution to which this Section 502(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Price reduction required by this Section 502(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Price reduction required by Sections 502(a) and (b) with respect to such dividend or distribution shall then be made), except (A) the Distribution Record Date of such dividend or distribution shall be substituted as "the date fixed for the determination of stockholders entitled to receive such dividend or other distribution" and "the date fixed for such determination" within the meaning of Sections 502(a) and (b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning of Section 502(a). (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding (x) 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 that such preceding quarterly dividend did not require any adjustment of the Conversion Price pursuant to this Section 502(e) (as adjusted to reflect subdivisions or combinations of the Common Stock), and (B) 3.75% of the arithmetic average of the Closing Price (determined as set forth in Section 502(h)) during the ten Trading Days (as defined in Section 502(h)) immediately prior to the date of declaration of such dividend, and (y) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary), then, in such case, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Distribution Record Date by a fraction of which the numerator shall be the Current Market Price of the Common Stock on the Distribution Record Date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Common Stock and the denominator shall be such Current Market Price of the Common Stock, such reduction to be effective immediately prior to the opening of business on the day following the Distribution Record Date; provided, however, that in the event the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Distribution 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 such Holder would have received had such Holder converted each Note on the Distribution Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If any adjustment is required to be made as set forth in this Section 502(e) 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 502(e) -10- 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. (f) 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 (as amended upon the expiration thereof) shall require the payment to stockholders 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 if Directors) that as of the last time (the "Expiration Time") tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) that exceeds the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that 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 Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer had not been made. (g) In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary for an amount which increases the offeror's ownership of Common Stock to more than 25% of the Common Stock outstanding and shall involve the payment by such Person of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) at the last time (the "Offer 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 Offer Expiration Time, and in which, as of the Offer Expiration Time the Board of Directors is not recommending rejection of the offer, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Offer Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the Offer Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the -11- aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Offer Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Accepted Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Accepted Purchased Shares) on the Offer Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, such reduction to become effective immediately prior to the opening of business on the day following the Offer Expiration Time. In the event that such Person is obligated to purchase shares pursuant to any such tender or exchange offer, but such Person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 502(g) shall not be made if, as of the Offer 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 Eight of the Indenture. (h) For purposes of this Section 502, the following terms shall have the meaning indicated: (1) "Closing Price" with respect to any securities on any day shall mean the closing sale price regular way on such day or, in case no such sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in each case on the New York Stock Exchange, or, if such security is not listed or admitted to trading on such Exchange, on the principal national security exchange or quotation system on which such security is quoted or listed or admitted to trading, or, if not quoted or listed or admitted to trading on any national securities exchange or quotation system, the average of the closing bid and asked prices of such security on the over-the-counter market on the day in question as reported by the National Quotation Bureau Incorporated, or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose, or a price determined in good faith by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof, whose determination shall be conclusive. (2) "Current Market Price" shall mean the average of the daily Closing Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that (1) if the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution or Fundamental Change requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 502(a), (b), (c), (d), (e), (f) or (g) occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event, (2) if the "ex" date for any event (other than the issuance, distribution or Fundamental Change requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 502(a), (b), (c), (d), (e), -12- (f) or (g) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event, and (3) if the "ex" date for the issuance, distribution or Fundamental Change requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Closing Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof in a manner consistent with any determination of such value for purposes of Section 502(d), (f) or (g), whose determination shall be conclusive and described in a resolution of the Board of Directors or such duly authorized committee thereof, as the case may be) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such "ex" date. For purposes of any computation under Section 502(f) or (g), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however, that if the "ex" date for any event (other than the tender or exchange offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 502(a), (b), (c), (d), (e), (f) or (g) occurs on or after the Expiration Time or Offer Expiration Time, as the case may be, for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "ex" date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution, (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (3) when used with respect to any tender or exchange offer means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time or Offer Expiration Time, as the case may be, of such offer. (3) "Distribution Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). -13- (4) "fair market value" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction. (5) "Trading Day" shall mean (x) if the applicable security is listed or admitted for trading on the New York Stock Exchange or another national security exchange, a day on which the New York Stock Exchange or another national security exchange is open for business or (y) if the applicable security is quoted on the Nasdaq National Market, a day on which trades may be made on thereon or (z) if the applicable security is not so listed, admitted for trading or quoted, any day other than a Saturday or Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close. (i) The Company may make such reductions in the Conversion Price, in addition to those required by Sections 502 (a), (b), (c), (d), (e), (f) and (g), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least twenty (20) days, the reduction is irrevocable during the period and the Board of Directors shall have made a determination that such reduction would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to holders of record of the Notes a notice of the reduction at least fifteen (15) days prior to the date the reduced Conversion Price takes effect, and such notice shall state the reduced Conversion Price and the period during which it will be in effect. (j) No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 502(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this 502 shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest. To the extent the Notes 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. (k) Whenever the Conversion Price is adjusted as herein provided, the Company shall promptly file with the Trustee and any conversion agent other than the Trustee an Officers' Certificate setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Price setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective and shall mail such notice of such -14- adjustment of the Conversion Price to the Holder of each Note at his last address appearing on the Security Register within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. (l) In any case in which this Section 502 provides that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Note converted after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 1403 of the Indenture. (m) For purposes of this Section 502, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. ARTICLE SIX REDEMPTION AT OPTION OF HOLDERS UPON A FUNDAMENTAL CHANGE Section 601 Right to Require Redemption. If there shall occur a Fundamental Change, then each Holder shall have the right, at such Holder's option, to require the Company to redeem all of such Holder's Notes, or any portion thereof that is an integral multiple of $1,000 principal amount, on the date (the "Repurchase Date", with such Repurchase Date for the purposes of Section 508 of the Indenture being a "Redemption Date") that is 30 days after the date of the Company Notice (as defined in Section 602 below) of such Fundamental Change (or, if such 30th day is not a Business Day, the next succeeding Business Day). Such repayment shall be made at the following prices (expressed as a percentage of principal amount) in the event of a Fundamental Change occurring during the 12-month period beginning August 1:
Year Percentage Year Percentage - ---- ---------- ---- ---------- 1997 . . . . . . . . . . . . 107% 2001 . . . . . . . . . . . . 103% 1998 . . . . . . . . . . . . 106 2002 . . . . . . . . . . . . 102 1999 . . . . . . . . . . . . 105 2003 . . . . . . . . . . . . 101 2000 . . . . . . . . . . . . 104
and 100% at August 1, 2004; provided in each case that if the Applicable Price with respect to the Fundamental Change is less than the Reference Market Price, the Company shall redeem such Notes at a price equal to the foregoing redemption price multiplied by the fraction obtained by dividing the Applicable Price by the Reference Market Price. In each case, the Company shall also pay to such Holders accrued interest to, but excluding, the Repurchase Date on the redeemed Notes; provided, -15- however, that interest installments where Stated Maturity is on such Repurchase Date will be paid to the Holder of such Notes, or one or more Predecessor Notes, of record at the close of business on the relevant Record Dates. Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented. Section 602 Provision of Company Notice. On or before the tenth day after the occurrence of a Fundamental Change, the Company, or, at its request the Trustee (which must be received by the Trustee at least five Business Days prior to the date the Trustee is requested to give notice as described below) in the name of and at the expense of the Company, shall mail or cause to be mailed to all Holders of record on the date of the Fundamental Change a notice (the "Company Notice") of the occurrence of such Fundamental Change and of the redemption right at the option of the Holders arising as a result thereof. Such notice shall be mailed in the manner and with the effect set forth in Article Eleven of the Indenture. The Company shall also deliver a copy of the Company Notice to the Trustee at such time as it is mailed to Holders. Each Company Notice shall specify the circumstances constituting the Fundamental Change, the Repurchase Date, the price at which the Company shall be obligated to redeem Notes, the latest time on the Repurchase Date by which the Holder must exercise the redemption right (the "Fundamental Change Expiration Time"), that the Holder shall have the right to withdraw any Notes surrendered prior to the Fundamental Change Expiration Time, a description of the procedure which a Holder must follow to exercise such redemption right and to withdraw any surrendered Notes, the place or places where the Holder is to surrender such Holder's Notes, and the amount of interest accrued on each Note to, but excluding, the Repurchase Date. No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders' redemption rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Article Six. Section 603 Procedures for Redemption. For a Note to be so redeemed at the option of the Holder, the Company must receive at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York or, at the option of such Holder, the Corporate Trust Office of the Trustee, such Note with the form entitled "Option to Elect Redemption Upon A Fundamental Change" on the reverse thereof duly completed, together with such Notes duly endorsed for transfer, on or before the Fundamental Change Expiration Time. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for redemption shall be determined by the Company, whose determination shall be final and binding absent manifest error. -16- Section 604 Deposit of Redemption Price. On or prior to the Repurchase Date, the Company will deposit with the Trustee or with one or more Paying Agents (or, if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 1003 of the Indenture) an amount of money sufficient to repay on the Repurchase Date all the Notes to be redeemed on such date at the appropriate redemption price, together with accrued interest to, but excluding, the Repurchase Date; provided that if such payment is made on the Repurchase Date it must be received by the Trustee or Paying Agent, as the case may be, by 10:00 a.m. New York City time, on such date. Payment for Notes surrendered for redemption (and not withdrawn) prior to the Fundamental Change Expiration Time will be made promptly (but in no event more than three Business Days) following the Repurchase Date by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear on Security Register. Section 605 Successive Consolidations, Mergers, Etc. In the case of consolidation, merger, conveyance, transfer or lease to which Section 1409 of the Supplemental Indenture applies, in which the Common Stock of the Company is changed or exchanged as a result into the right to receive securities, cash or other property which includes shares of Common Stock of the Company or 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 constitute at the time such change or exchange becomes effective in excess of 50% of the aggregate fair market value of such securities, cash and other property (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 (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) modifying the provisions of the Indenture and this Supplemental Indenture, as applicable, relating to the right of Holders of the Notes to cause the Company to redeem the Notes following a Fundamental Change, including without limitation the applicable provisions of this Article Six and the definitions of the Applicable Price, Common Stock, Fundamental Change and Reference Market Price, as appropriate, as determined in good faith by the Company (which determination shall be conclusive and binding), to make such provisions apply to the common stock and the issuer thereof if different from the Company and Common Stock of the Company (in lieu of the Company and the Common Stock of the Company). ARTICLE SEVEN MISCELLANEOUS Section 701 Consent of Holders Required. In addition to those modifications or amendments requiring the consent of the Holder of each Outstanding Note effected thereby specified in Section 902 of the Indenture, there can be no modification or amendment that would change the obligation of the Company to redeem any Note -17- upon the happening of a Fundamental Change in a manner adverse to the Holder of Notes without the consent of the Holder of each outstanding Note effected thereby. Section 702 Applicability of Certain Indenture Provisions. Each of the defeasance and covenant defeasance provisions of Article Thirteen of the Indenture shall apply to the Notes; provided, however, that the Company will not be able to defease the right of the Holders to convert the Notes pursuant to Article Fourteen of the Indenture. Section 703 Reference to and Effect on the Indenture.

This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $287,500,000, and is issued pursuant to a Supplemental Trust Indenture supplementing the Indenture, dated as of August 1, 1997, from the Company to Trustee relating to the issuance of the "7% Convertible Notes due 2004" of this series (the "Supplemental Indenture"). The Securities will not be subject to redemption prior to August 1, 1999 and will be redeemable on and after such date at the option of the Company, in whole or in part, upon not less than 15 nor more than 60 days' notice to the Holders, at the Redemption Prices (expressed as a percentage of principal amount) set forth below; provided, however, that the Securities will not be redeemable following August 1, 1999, and before August 1, 2001, unless the Closing Price of the Company's Common Stock is at least 125% of the Conversion Price for at least 20 Trading Days within a period of 30 consecutive Trading Days ending within five Trading Days prior to the notice of redemption. The Redemption Price (expressed as a percentage of principal amount) is as follows for the 12-month periods beginning on August 1 of the following years:

The Securities are not subject to redemption through operation of any sinking fund. -22- In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. If a Fundamental Change (as defined in the Supplemental Indenture) occurs at any time prior to August 1, 2004, the Securities will be redeemable on the 30th day after notice thereof at the option of the Holder. Such payment shall be made at the following prices (expressed as a percentage of principal amount) in the event of a Fundamental Change occurring during the 12-month period beginning August 1 of the following years:
YEAR PERCENTAGE YEAR PERCENTAGE - ---- ---------- ---- ---------- 1997.................... 107% 2001............... 103% 1998.................... 106 2002............... 102 1999.................... 105 2003............... 101 2000.................... 104

In each case, the Company shall also pay accrued interest, if any, on such Securities to, but excluding, the Repurchase Date; provided, however, that interest installments whose Stated Maturity is on such Repurchase Date will be paid to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Supplemental Indenture. The Company shall mail to all Holders a notice of the occurrence of a Fundamental Change and of the redemption right arising as a result thereof on or before the 10th day after the occurrence of such Fundamental Change. For a Security to be so repaid at the option of the Holder, the Company must receive at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, the City of New York, or, at the option of the Holder, the Corporate Trust Office of the Trustee, such Security with the form entitled "Option to Elect Redemption Upon a Fundamental Change" on the reverse thereof duly completed, together with such Securities 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 immediately succeeding Business Day). The indebtedness evidenced by this Security is, to the extent and in the manner provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness of the Company, and this Security is issued subject to such provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee as his or her attorney-in-fact for any and all such purposes. The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each -23- case upon compliance with certain conditions set forth in the Indenture, except that the Company will not be able to defease the right of the Holders to convert this Security pursuant to Article Fourteen of the Indenture. Subject to the provisions of the Indenture, the Holder of this Security is entitled, at its option, at any time on or before August 1, 2004 (except that, in case this Security or any portion hereof shall be redeemed, such right shall terminate with respect to this Security or portion hereof, as the case may be, so redeemed at the close of business on the first Business Day next preceding the date fixed for redemption as provided in the Indenture, unless the Company defaults in making the payment due upon redemption or except as otherwise provided in the Indenture), to convert the principal amount of this Security (or any portion hereof which is $1,000 or an integral multiple thereof) into fully paid and non-assessable shares of the Common Stock of the Company, as said shares shall be constituted at the date of conversion, at the initial Conversion Price of $46.325 or at the adjusted Conversion Price in effect at the date of conversion determined as provided in the Indenture, upon surrender of this Security, together with the conversion notice hereon duly executed, to be accompanied (if so required by the Company) by instruments of transfer, in form satisfactory to the Company and to the Trustee, duly executed by the Holder or by its duly authorized attorney in writing. Such surrender shall, if made during any period beginning at the close of business on a Regular Record Date and ending at the opening of business on the Interest Payment Date next following such Regular Record Date (unless this Security or the portion being converted shall have been called for redemption on a Redemption Date during the period beginning at the close of business on a Regular Record Date and ending at the opening of business on the first Business Day after the next succeeding Interest Payment Date, or if such Interest Payment Date is not a Business Day, the second such Business Day), also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of this Security then being converted. Subject to the aforesaid requirement for payment and, in the case of a conversion after the Regular Record Date next preceding any Interest Payment Date and on or before such Interest Payment Date, to the right of the Holder of this Security (or any Predecessor Security) of record at such Regular Record Date to receive an installment of interest (with certain exceptions provided in the Indenture), no adjustment is to be made on conversion for interest accrued hereon or for dividends on shares of Common Stock issued on conversion. The Company is not required to issue fractional shares upon any such conversion, but shall make adjustment therefor as provided in the Indenture. The Conversion Price is subject to adjustment as provided in the Indenture. In the event of conversion of this Security in part only, a new Security or Securities for the unconverted portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of more than 50% in principal amount of the Securities at the -24- time Outstanding of each series to be affected.
