The term "Custodian" means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. Section 6.2 Acceleration. If an Event of Default (other than an Event of Default specified in clause (f) or (g) of Section 6.1) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities by notice to the Company and the Trustee, may declare the unpaid principal of and any accrued interest on all the Securities to be due and payable. Upon such declaration the principal and interest shall be due and payable immediately. If an Event of Default specified in clause (f) or (g) of Section 6.1 occurs, such an amount shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the then outstanding Securities by written notice to the Trustee 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 (except nonpayment of principal or interest that has become due solely because of the acceleration) have been cured or waived. Section 6.3 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy occurring upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. Section 6.4 Waiver of Past Defaults. Holders of a majority in principal amount of the then outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except a continuing Default or Event of Default in the payment of the principal or interest on any Security held by a non-consenting Holder. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture. No such waiver shall extend to any subsequent or other Default or impair any right consequent on any subsequent or other Default. 053113\1008\02764\979QGT85.OTH 32 Section 6.5 Control by Majority. The Holders of a majority in principal amount of the outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on such Trustee; provided that (a) such direction is not in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action it deems proper that is not inconsistent with such direction and (c) such Holders have offered to the Trustee indemnity as provided in Section 7.1(e). Section 6.6 Limitation on Suits. No Holder of any of the Securities shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee or for any other remedy under this Indenture, unless: (a) such Holder has previously given notice to the Trustee of a continuing Event of Default; (b) the Holders of not less than 25% in principal amount of the outstanding Securities have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under this Indenture; (c) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (d) the Trustee for 30 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (e) no direction inconsistent with such written request has been given to the Trustee during such 30-day period by the Holders of a majority in principal amount of the outstanding Securities. A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. Section 6.7 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal and interest on the Security, on or after the respective due dates expressed in the Security, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder. 053113\1008\02764\979QGT85.OTH 33 Section 6.8 Collection Suit by Trustee. If an Event of Default specified in Section 6.1(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company or any other obligor for the whole amount of principal and interest remaining unpaid on the Securities and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. Section 6.9 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Securities), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and if the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders of the Securities may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. Section 6.10 Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: First: to the Trustee, its agents and attorneys for amounts due under Section 7.7, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection. 053113\1008\02764\979QGT85.OTH 34 Second: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and Third: to the Company or to such party as a court of competent jurisdiction shall direct. The Trustee may fix a record date and payment date for any payment to Holders. Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorney' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7, or a suit by Holders of more than 10% in principal amount of the then outstanding Securities. ARTICLE VII TRUSTEE Section 7.1 Duties of a Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

(ii) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however, that the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. 053113\1008\02764\979QGT85.OTH 35 (c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (i) this paragraph does not limit the effect of paragraph (b) of this Section 7.1; (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5. (d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to the provisions of this Section 7.1. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability or expense. (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

Section 7.3 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights; provided, however, the Trustee is subject to Sections 7.10 and 7.11. Section 7.4 Trustee's Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture, the Securities or any documents relating to the Securities. It shall not be accountable for the Company's use of the proceeds from the Securities or any money paid to the Company or upon the Company's discretion under any provision hereof. It shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee and it shall not be responsible for any statement or recital herein or any statement in the Securities or any other document in connection with the sale of the Securities or pursuant to this Indenture, other than its certificate of authentication. Section 7.5 Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders a notice of the Default or Event of Default within 90 days after it occurs. A Default or an Event of Default shall not be considered known to the Trustee unless it is a Default or Event of Default under Section 6.1(a) or (b) or the Trustee shall have received notice thereof, in accordance with this Indenture, from the Company or from the Holders of a majority in principal amount of the outstanding Securities, and in the absence of such notice the Trustee may conclusively assume there is no Default or Event of Default. Except in the case of a Default or Event of Default in payment of principal or interest on any Security (including the failure to make a mandatory redemption pursuant hereto), the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Holders. 053113\1008\02764\979QGT85.OTH 37 Section 7.6 Reports by Trustee to Holders. Within 60 days after each August 1 beginning with the August 1 following the date hereof, the Trustee shall mail to Holders a brief report dated as of such reporting date that complies with TIA S 313(a) (but if no event described in TIA S 313(a) has occurred within the 12 months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA S 313(n). The Trustee shall also transmit by mail all reports as required by TIA S 313(c).

Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel.

To secure the Company's payment obligations in this Section, the Trustee shall have a Lien with priority over the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Securities. Such Lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(f) or (g) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 053113\1008\02764\979QGT85.OTH 38 Section 7.8 Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Truste's acceptance of appointment as provided in this Section 7.8.

Section 9.2 With Consent of Holders. Except as provided below in this Section 9.2, the Company and the Trustee may amend this Indenture or the Securities with the written consent of the Holders of at least a majority in principal amount of the then outstanding Securities. The Holders of a majority in principal amount of the Securities then outstanding may, or the Trustee with the written consent of the Holders of at least a majority in principal amount of the then outstanding Securities may, waive compliance in a particular instance by the Company with any provision of this Indenture or the Securities. Upon the request of the Company, accompanied by a resolution of its Board of Directors authorizing the execution of any such Supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.6 hereof, the Trustee shall join with the Company in the execution of such Supplemental Indenture unless such Supplemental Indenture affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such Supplemental Indenture. It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment or waiver under this Section becomes effective, the Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such Supplemental Indenture or waiver. Subject to Sections 6.4 and 6.7 hereof, the Holders of a majority in principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Securities, provided, however, that without the consent of each Holder affected, an amendment or waiver under this Section may not (with respect to any Securities held by a non-consenting Holder): (a) reduce the principal amount of Securities whose Holders must consent to an amendment or waiver; (b) reduce the rate of or change the time for payment of interest, including default interest, on any Security; 053113\1008\02764\979QGT85.OTH 44 (c) reduce the principal of or change the fixed maturity of any Security or alter the optional or mandatory redemption provisions or the price at which the Company shall offer to purchase such Securities pursuant to Sections 3.7 and 4.10 hereof; (d) make any Security payable in money other than that stated in the Security; (e) make any change in Section 6.4 or 6.7 hereof or in this sentence of this Section 9.2; or (f) waive a Default in the payment of principal of, premium or interest on, or redemption payment with respect to, any Security. Section 9.3 Compliance with Trust Indenture Act. Every amendment to this Indenture or the Securities shall be set forth in a Supplemental Indenture that complies with the TIA as then in effect. Section 9.4 Revocation and Effect of Consents. Until an amendment or waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security; provided, however, that any such Holder or subsequent Holder may revoke the consent as to his or her security if the Trustee receives written notice of revocation before the date the waiver or amendment becomes effective. An amendment or waiver becomes effective in accordance with its terms and thereafter binds every Holder. The Company may fix a record date for determining which Holders must consent to such amendment or waiver. If the Company fixes a record date, the record date shall be fixed at (a) the later of 30 days before the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee before such solicitation pursuant to Section 2.05, or (b) such other date as the Company shall designate. Section 9.5 Notation on or Exchange of Securities. The Trustee may place an appropriate notation about an amendment or waiver on any Security thereafter authenticated. The Company in exchange for all Securities may issue and the Trustee shall authenticate new Securities of the same series that reflect the amendment or waiver. Failure to make the appropriate notation or issue a new Security of the same series shall not affect the validity and effect of such amendment or waiver. 053113\1008\02764\979QGT85.OTH 45 Section 9.6 Trustee to Sign Amendments, etc. The Trustee shall sign any amendment or Supplemental Indenture authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee.

The Company may not sign an amendment or Supplemental Indenture until the Board of Directors approves it. ARTICLE X CONVERSION Section 10.1 Right to Convert. (a) Subject to and upon compliance with the provisions of this Indenture, at any time on or after 270 days after the Issue Date and on or before maturity, each Holder shall have the right, at its option, to convert the principal amount of any Security, or any portion of such principal amount which is $1,000 or a whole multiple thereof, into, at the Company's option, either (i) cash, payable by the Company to the Paying Agent for the benefit of such Holder in an amount equal to the Current Market Price, as of the conversion date, of the Common Stock to which the Securities would otherwise be converted, or (ii) that number of fully paid and nonassessable shares of Common Stock (as such shares shall then be constituted) obtained by dividing the principal amount of the Security or portion thereof surrendered for conversion by the conversion price in effect at such time, or (iii) a combination of cash and Common Stock in proportions determined by the Company in its sole discretion; provided, however, that the Company's option to convert Securities into cash under Section 10.1(a)(i) or into a combination of cash and Common Stock under Section 10.1(a)(iii), shall terminate at the close of business on the date the Company's charter is amended to increase the number of shares of authorized Common Stock to at least that number of shares sufficient to reserve for the conversion of all the Notes. (b) Notwithstanding anything in this Section 10.1 to the contrary, the right to convert with respect to any Security or portion of a Security that shall be called for redemption or delivered for repurchase, shall terminate at the close of business on the date fixed for redemption of such Security or portion of a Security on the second trading day preceding a Change in Control Payment Date, as the case may be, unless the Company shall default in payment due upon redemption or repurchase thereof. (c) A holder of Securities is not entitled to any rights of a holder of Common Stock until such holder has converted his Securities to Common Stock, and only to the extent such Securities are deemed to have been converted to Common Stock under this Article 10. 053113\1008\02764\979QGT85.OTH 46 Section 10.2 Exercise of Conversion Privilege; Issuance of Common Stock on Conversion; No Adjustment for Interest or Dividends. In order to exercise the conversion privilege, the Holder of any Security to be converted in whole or in part shall surrender such Security, duly endorsed, at an office or agency maintained by the Company pursuant to Section 2.3, accompanied by the funds, if any, required by the last paragraph of this Section 10.2, and shall give written notice of conversion in the form provided on the Securities (or such other notice that is acceptable to the Company) to the Company at such office or agency that the Holder elects to convert such Security or the portion thereof specified in such notice, stating the name or names (with address) in which the certificate or certificates for shares of Common Stock, if any, that shall be issuable on such conversion shall be issued. So long as the Company's option to convert Securities into cash or a combination of cash and Common Stock exists, then within five business days after receipt of such Holder's notice of conversion, the Company shall notify such Holder of the Company's election to convert the Securities to cash or, Common Stock, or a combination of cash and Common Stock. Holder shall then deliver to the Company any transfer taxes required pursuant to Section 10.7. Each Security surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the registration under such Security, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or his duly authorized attorney. Holder may not withdraw its conversion notice after receipt of the Company's notice of its election regarding conversion. As promptly as practicable after the surrender of such Security and the receipt of such notice and funds, if any, as aforesaid, (a) if the conversion is for Common Stock, the Company shall issue and shall deliver at such office or agency to such Holder, or on his written order, (i) a certificate or certificates for the number of full shares issuable upon the conversion of such Security or portion thereof in accordance with the provisions of this Article, and (ii) a check or cash in respect of any fractional interest in respect of a share of Common Stock arising upon such conversion as provided in Section 10.3, or (b) if the conversion is for cash or a combination of cash and Common Stock, the Company shall, one business day after its notice to Holder of the Company's election regarding conversion, deposit with Paying Agent money sufficient to pay the conversion price for, and all accrued interest on, the Securities being converted to cash. In case any Security of a denomination greater than $1,000 shall be surrendered for partial conversion, and subject to Article 2, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the holder of the Note so surrendered, without charge to him, a new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Security. Each conversion shall be deemed to have been effected on the date on which such Security shall have been surrendered (accompanied by the funds, if any, required by the last paragraph of this Section 10.2) and such notice shall have been received by the Company, as aforesaid, and, if the conversion is for Common Stock, the person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on said date the holder of record of the shares represented thereby; provided, however, that any such surrender on any date when the stock transfer books of the Company shall be closed shall constitute the person in whose name the certificates are to be 053113\1008\02764\979QGT85.OTH 47 issued as the record holder thereof for all purposes on the next day on which such stock transfer books are open, but such conversion shall be at the conversion price in effect on the date upon which such Security shall have been surrendered. Any Security or portion thereof surrendered for conversion during the period from the close of business on the record date for any interest payment date to the opening of business on such interest payment date shall (unless such Security or portion thereof being converted shall have been called for redemption on a date in such period) be accompanied by payment, in funds acceptable to the Company, of an amount equal to the interest otherwise payable on such interest payment date on the principal amount being converted; provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment of interest on the Securities. An amount equal to such payment shall be paid by the Company on such interest payment date to the holder of such Security at the close of business on such record date; provided, however, that if the Company shall default in the payment of interest on such interest payment date, such amount shall be paid to the person who made such required payment. Except as provided above in this Section 10.2, no adjustment shall be made for interest accrued on any Security converted or for dividends on any shares issued upon the conversion of such Security as provided in this Article 10. If any Security or portion thereof which has been called for redemption on a date during the period from the close of business on the record date for any interest payment date to the opening of business on such interest payment date is surrendered for conversion during such period, no interest shall be payable to the holder of such Security on account of such Security or portion thereof. Section 10.3 Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip representing fractional shares shall be issued upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of Common Stock would be issuable upon the conversion of any Security or Securities, the Company shall make an adjustment therefor in cash at the current market value thereof. The current market value of a share of Common Stock shall be the Closing Price on the day (that is not a Legal Holiday as defined in Section 12.8) before the day on which the Securities (or specified portions thereof) are deemed to have been converted and such Closing Price shall be determined as provided in subsection (f) of Section 10.5. Section 10.4 Conversion Price. The conversion price shall be as specified in the form of Security hereinabove set forth, subject to adjustment as provided in this Article. 053113\1008\02764\979QGT85.OTH 48 Section 10.5 Adjustment of Conversion Price. (a) 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 price 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 of the Company that he would have owned or have been entitled to receive after the happening of any of the events described above had such Security been converted immediately before the happening of such event. An adjustment made pursuant to this subsection (a) shall become effective immediately after the record date in the case of a dividend and shall become effective immediately after the effective date in the case of subdivision or combination. (b) In case the Company shall issue rights or warrants to all holders of 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, except as provided in subsection (f) below, the conversion price in effect immediately prior thereto shall be adjusted so that the same shall equal the price determined by multiplying the conversion price in effect immediately before 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 shares which the aggregate offering price of the total number of shares so offered would purchase at such Current Market Price (determined by multiplying the total number of shares by the exercise price of such rights or warrants and dividing the product so obtained by the Current Market Price), and of which the denominator 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 for subscription or purchase. Such adjustment shall be made successively whenever any such rights or warrants are issued, and shall become effective immediately after such record date. Except as provided in subsection (f) below, 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 of the Company whose determination shall be conclusive and described in a certificate filed with the Trustee. Upon the expiration of any right or warrant to purchase Common Stock the issuance of which resulted in an adjustment in the conversion price pursuant to this subsection (b), if any such right or warrant shall expire and shall not have been exercised, the conversion price shall immediately upon such expiration be recomputed to the conversion price which would have been in effect had the adjustment of the conversion price made upon the issuance of such rights or warrants been made on the basis of offering for subscription or purchase only that number of shares of Common Stock actually purchased upon the exercise of such rights or warrants actually exercised. 053113\1008\02764\979QGT85.OTH 49 (c) In case the Company shall distribute to all holders of its Common Stock any shares of Capital Stock of the Company (other than Common Stock) or evidences of its indebtedness or assets (excluding cash dividends or other distributions to the extent paid from retained earnings of the Company) or rights or warrants to subscribe for or purchase any of its securities (excluding those referred to in subsection (b) above), then, except as provided in subsection (f) below, in each such case the conversion price shall be adjusted so that the same shall equal the price determined by multiplying the conversion price in effect immediately before the date of such distribution by a fraction of which the numerator shall be the Current Market Price per share (as defined in subsection (f) below) of the Common Stock on the record date mentioned below 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 portion of the Capital Stock or assets or evidences of indebtedness so distributed or of such rights or warrants applicable to one share of Common Stock, and the denominator shall be the market price per share (as defined in subsection (f) below) of the Common Stock on such record date. Such adjustment shall become effective immediately after the record date for the determination of stockholders entitled to received such distribution, except as provided in subsection (f) below. (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash in an aggregate amount that, combined together with (1) the aggregate amount of any other distributions to all holders of its Common Stock made exclusively in cash within the 12 months preceding the date of payment of such distribution and in respect of which no adjustment pursuant to this paragraph (d) has been made and (2) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) of consideration payable in respect of any tender offer by the Company or any of its Subsidiaries for all or any portion of the Common Stock concluded within the 12 months preceding the date of payment of such distribution and in respect of which no adjustment pursuant to paragraph (e) of this Section has been made, exceeds 10% of the product of the Current Market Price per share of the Common Stock on the date for the determination of holders of shares of Common Stock entitled to receive such distribution times the number of shares of Common Stock outstanding on such date, then, and in each such case, immediately after the close of business on such date for determination, the conversion price shall be reduced so that the same shall equal the price determined by multiplying the conversion price in effect immediately before the close of business on the date fixed for determination of the stockholders entitled to receive such distribution by a fraction (i) the numerator of which shall be equal to the Current Market Price per share of the Common Stock on the date fixed for such determination less an amount equal to the quotient of (x) the excess of such combined amount over such 10% and (y) the number of shares of Common Stock outstanding on such date for determination and (ii) the denominator of which shall be equal to the Current Market Price per share of the Common Stock on such date for determination. (e) In case a tender offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender offer (as amended at the time of the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchase Shares (as defined below) of an aggregate consideration having a fair market value (as determined by the Board of Directors, 053113\1008\02764\979QGT85.OTH 50 whose determination shall be conclusive and described in a Board Resolution) that combined together with (1) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) as of the expiration of such tender offer, of consideration payable in respect of any other tender offer, by the Company or any Subsidiary for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this paragraph (e) has been made and (2) the aggregate amount of any distributions to all holders of the Company's Common Stock made exclusively in cash within 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to paragraph (d) of this Section has been made, exceeds 10% of the product of the Current Market Price per share of the Common Stock as of the last time (the "Expiration Time") tenders could have been made pursuant to such tender offer (as it may be amended) times the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time, then, and in each such case, immediately before the opening of business on the day after the date of the Expiration Time, the conversion price shall be adjusted so that the same shall equal the price determined by multiplying the conversion price in effect immediately before close of business on the date of the Expiration Time by a fraction (i) the numerator of which shall be equal to (A) the product of (1) the Current Market Price per share of the Common Stock on the date of the Expiration Time and (2) the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time, less (B) the amount of cash plus 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 offer) of Purchased Shares, and (ii) the denominator of which shall be equal to the product of (A) the Current Market Price per share of the Common Stock as of the Expiration Time and (B) the number of shares of Common Stock outstanding (including any tendered shares) as of the Expiration Time less the number of all shares validly tendered 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"). (f) 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 subsection (f) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 10 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. Anything in this Section 10.5 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the conversion price, in addition to those required by this Section 10.5, as it in its discretion shall determine to be advisable in order that any stock dividends, subdivision of shares, distribution of rights to purchase stock or securities, or a distribution of securities convertible into or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. (g) 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 053113\1008\02764\979QGT85.OTH 51 adjusted conversion price and the date on which such adjustment becomes effective and shall mail or cause to be mailed such notice of such adjustment of the conversion price to the Holder of each Security at his last address appearing on the Security register provided for in Section 2.3 of this Indenture. (h) In any case in which this Section 10.5 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 Security converted after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the 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 10.3. Section 10.6 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 shall occur, then the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall conform to the TIA as in force at the date of execution of such 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 before 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 his address appearing on the Security register provided for in Section 2.3 of this Indenture. The above provisions of this Section 10.6 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. Section 10.7 Taxes on Shares Issued. The issue of stock certificates on conversions of Securities shall be made without charge to the converting Holder of Securities for any tax in respect of the issue thereof. The 053113\1008\02764\979QGT85.OTH 52 Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Security converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. Section 10.8 Reservation of Shares; Shares to be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock. The Company shall use its best efforts, including asking its stockholders to authorize additional Common Stock to provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Securities from time to time as such Securities are presented for conversion. Before taking any action which would cause an adjustment reducing the conversion price below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted conversion price. The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 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 Common Stock shall be listed on the American Stock Exchange or any other national securities exchange the Company will, if permitted by the rules of such exchange, list and keep listed so long as the Common Stock shall be so listed on such exchange, all Common Stock issuable upon conversion of the Securities. Section 10.9 Responsibility of Trustee. The Trustee and any other conversion agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist which may require any adjustment of the conversion price or other adjustment or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other conversion agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or 053113\1008\02764\979QGT85.OTH 53 property, which may at any time be issued or delivered upon the conversion of any Security; and the Trustee and any other conversion agent make no representations with respect thereto. Subject to the provisions of Section 7.1, neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Security for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 10. Without limiting the generality of the foregoing, neither the Trustee nor any conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 10.6 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders of Securities upon the conversion of their Securities after any event referred to in Section 10.6 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.1, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers' Certificate (which the Company shall be obligated to file with the Trustee before the execution of any such supplemental indenture) with respect thereto. Section 10.10 Notice to Holders Before Certain Actions. In case: (a) the Company shall declare a dividend (or any other distribution) on its Common Stock (other than in cash out of retained earnings); or (b) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any shareholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or (d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; or (e) of an increase in the interest rate on the Securities pursuant to the Registration Rights Agreement, the Company shall cause to be filed with the Trustee and to be mailed to each Holder of Securities at his address appearing on the Securities Register provided for in Section 2.3 of this Indenture, as promptly as possible but in any event at least fifteen days before the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights, or, if a record is not to be taken, the date as of which the 053113\1008\02764\979QGT85.OTH 54 holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occurring and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. ARTICLE XI SUBORDINATION Section 11.1 Agreement to Subordinate. The Company agrees, and each Holder by accepting a Security agrees, that the indebtedness evidenced by the Securities, and any guarantee of that indebtedness, is subordinated in right of payment, to the extent and in the manner provided in this Article, to the prior payment in full of all Senior Indebtedness, and that the subordination is for the benefit of the holders of Senior Indebtedness. Section 11.2 Certain Definitions. "Senior Indebtedness" means: (a) the principal of, interest (including, to the extent permitted by applicable law, interest on or after the commencement of a proceeding referred to in clauses (f) or (g) of Section 6.1 whether or not representing an allowed claim in such proceeding) and premium, if any, on and any other amounts owing with respect to (i)any indebtedness of the Company, now or hereafter outstanding, in respect of borrowed money (other than the Securities and the Existing Debentures), (ii)any indebtedness of the Company, now or hereafter outstanding (other than the Securities and the Existing Debentures), evidenced by a bond, note, debenture, capitalized lease, letter of credit or other similar instrument, (iii)any other written obligation of the Company, now or hereafter outstanding, to pay money issued or assumed as all or part of the consideration for the acquisition of property, assets or securities, including without limitation, interest rate swap agreements, currency hedging obligations, hedging obligations with respect to the purchase or sale of oil and gas, and any other hedging agreement entered into in the ordinary course of business and (iv)any guaranty or endorsement (other than for collection or deposit in the ordinary course of business) or discount with recourse of, or other agreement (contingent or otherwise) to purchase, repurchase or otherwise acquire, to supply or advance funds or to become liable with respect to (directly or indirectly), any indebtedness or obligation of any person of the type referred to in the preceding subclauses (i), (ii) and(iii) now or hereafter outstanding; and 053113\1008\02764\979QGT85.OTH 55 (b) any refundings, refinancings, renewals or extensions of any indebtedness or other obligation described in clause (a) of this Section 11.2. Notwithstanding the foregoing (i) if, by the terms of the instrument creating or evidencing any indebtedness or obligation referred to in clauses (a) or (b) above, it is expressly provided that such indebtedness or obligation is not senior in right of payment to the Securities, such indebtedness or obligation shall not be included as Senior Indebtedness, and (ii) the Notes shall be, pari passu, in right of payment with the Existing Debentures, except that the Existing Debentures have the benefit of guarantees by the Company's Subsidiaries. "Representative" means the indenture trustee or other trustee, agent or representative for an issue of Senior Indebtedness. Section 11.3 Liquidation; Dissolution; Bankruptcy. Upon any distribution to creditors of the Company in a liquidation, dissolution or winding up of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property: (1) holders of Senior Indebtedness shall be entitled to receive payment in full, in cash or in a manner satisfactory to the holders of such Senior Indebtedness, of all Senior Indebtedness before Holders shall be entitled to receive, from the Company or from any guarantor of the Obligations under this Indenture and the Notes, any payments of principal of or premium, if any, or interest on Securities; and (2) until the Senior Indebtedness is paid in full in cash or in a manner satisfactory to the holders of such Senior Indebtedness, any distribution to which Holders would be entitled but for this Article shall be made to holders of Senior Indebtedness as their interest may appear, except that Holders may receive securities that are subordinated to Senior Indebtedness to at least the same extent as the Securities. A distribution may consist of cash, securities or other property. Section 11.4 Company Not to Make Payments with Respect to Securities in Certain Circumstances. (a) Upon the maturity of any Senior Indebtedness by lapse of time, acceleration or otherwise, all principal thereof, premium, if any, and interest thereon and any other amounts owing in respect thereof shall first be paid in full, or such payment duly provided for in cash or in a manner satisfactory to the holders of such Senior Indebtedness, before any payment is made on account of the principal of or premium, if any, or interest on the Securities or to acquire any of the Securities. 053113\1008\02764\979QGT85.OTH 56 (b) Upon the happening of an event of default (or if any event of default would result upon any payment upon or with respect to the Securities) with respect to any Senior Indebtedness as such event of default is defined therein or in the instrument under which it is outstanding, permitting holders to accelerate the maturity thereof, and, if the default is other than default in payment of the principal of, premium, if any, or interest on or any other amount owing in respect of such Senior Indebtedness, upon written notice thereof given to the Company and the Trustee by the holders of Senior Indebtedness or their Representative, then, unless such an event of default shall have been cured or waived or shall have ceased to exist, no payment shall be made by the Company or any guarantor with respect to the principal of or premium, if any, or interest on the Securities or to acquire any of the Securities. Section 11.5 Acceleration of Securities. If payment of the Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of the acceleration. Section 11.6 When Distribution Must Be Paid Over. If a distribution is made to Holders that, because of this Article 11, should not have been made to them, the Holders who receive the distribution shall hold it in trust for holders of Senior Indebtedness and pay it over to them as their interests may appear. Section 11.7 Notice by Company. The Company shall promptly notify the Trustee and the Paying Agent of any facts known to the Company that would cause a payment of principal of or premium, if any, or interest on the Securities to violate this Article 11. Section 11.8 Subrogation. After all Senior Indebtedness is paid in full and until the Securities are paid in full, Holders shall be subrogated to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness to the extent that distributions otherwise payable to the Holders have been applied to the payment of Senior Indebtedness. A distribution made under this Article 11 to holders of Senior Indebtedness which otherwise would have been made to Holders is not, as between the Company and Holders, a payment by the Company on Senior Indebtedness. Section 11.9 Relative Rights. This Article 11 defines the relative rights of Holders and holders of Senior Indebtedness. Nothing in this Indenture shall: (1) impair, as between the Company and Holders, the obligation of the Company, which is absolute and unconditional, to pay principal of and premium, if any, and interest on the Securities in accordance with their terms; 053113\1008\02764\979QGT85.OTH 57 (2) affect the relative rights of Holders and creditors of the Company, other than holders of Senior Indebtedness and any guarantors of the Obligation under this Indenture and the Notes; or (3) prevent the Trustee or any Holder from exercising its available remedies upon a Default, subject to the rights of holders of Senior Indebtedness to receive distributions otherwise payable to Holders. If the Company fails because of this Article 11 to pay principal of or premium, if any, or interest on a Security on the due date, such failure shall nevertheless be deemed a Default. Section 11.10 Subordination May Not Be Impaired by Company. No right of any holder of Senior Indebtedness to enforce the subordination of the indebtedness evidenced by the Securities shall be impaired by any act or failure to act by the Company or by its failure to comply with the terms of this Indenture. Section 11.11 Distribution or Notice to Representative. Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness, the distribution may be made and the notice given to their Representative. Section 11.12 Rights of Trustee and Paying Agent. Notwithstanding any provisions of this Indenture to the contrary, the Trustee and any Paying Agent may continue to make payments on the Securities and shall not at any time be charged with knowledge of the existence of any facts which would prohibit the making of such payments until it receives written notice (received by a Responsible Officer, in the case of the Trustee) reasonably satisfactory to it that payments may not be made under this Article 11 and, before the receipt of any such notice, the Trustee, subject to the provisions of Article 7, and any agent shall be entitled to assume conclusively that no such facts exist. The Company, an Agent, a Representative or a holder of Senior Indebtedness may give the notice. If an issue of Senior Indebtedness has a Representative, only the Representative (or any Representative, if more than one) may give the notice with respect to such Senior Indebtedness. The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a Representative) to establish that such notice has been given by a holder of Senior Indebtedness (or a Representative), and shall be entitled to rely on any written notice by a Person representing himself to be a holder of Senior Indebtedness to the effect that such issue of Senior Indebtedness has no Representative. Any deposit of moneys by the Company with the Trustee or any Paying Agent (whether or not in trust) for the payment of the principal of or premium, if any, or interest on, or payment on account of Change in Control, if any, of, any Securities shall be subject to the 053113\1008\02764\979QGT85.OTH 58 provisions of this Article 11, except that if, at least three business days before the date on which by the terms of this Indenture any such moneys may become payable for any purpose (including, without limitation, the payment of principal of or premium, if any, or interest on any Security), the Trustee shall not have received with respect to such moneys the notice provided for in this Section 11.12, then the Trustee shall have full power and authority to receive such moneys and to apply the same to the purpose for which they were received and shall not be affected by any notice to the contrary which may be received by it within three business days before or on or after such date. This Section 11.12 shall be construed solely for the benefit of the Trustee and Paying Agent and shall not otherwise affect the rights of holders of Senior Indebtedness. If the Trustee determines in good faith that further evidence is required with respect to the right of any Person as holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article 11, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of the Senior Indebtedness held by such Person, the extent to which such person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 11, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive payment. The Trustee shall not be deemed to owe any fiduciary duty to holders of Senior Indebtedness by virtue of the provisions of this Article 11. The Trustee's responsibilities to the holders of Senior Indebtedness are limited to those set forth in this Article 11, and no implied covenants or obligations shall be read into this Indenture. The Trustee shall not become liable to the holders of Senior Indebtedness if it makes a payment prohibited by this Article 11 in good faith. The Trustee in its individual or any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee. Any agent may do the same with like rights. Section 11.13 Effectuation of Subordination by Trustee. Each Holder of Securities, by acceptance thereof, authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effect the subordination provided in this Article 11 and appoints the Trustee his attorney-in-fact for any and all such purposes.

Section 12.9 No Recourse Against Others.

The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts.

Initially, the Trustee shall act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co- Registrar without notice to any Holder. The Company and any of its Subsidiaries may act in any such capacity. Section 4. Indenture. The Company issued the Notes under an Indenture, dated as of September 25, 1997 (the "Indenture"), among the Company and American Stock Transfer & Trust Company, as Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code SS 77aaa-77bbbb), as amended by the Trust Indenture Reform Act of 1990, and as in effect on the date of the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The terms of the Indenture shall govern any inconsistencies between the Indenture and the Notes. Capitalized terms used herein that are not specifically defined herein shall have the meanings set forth in the Indenture. The Notes are unsecured general obligations of the Company limited to $216,000,000 in aggregate principal amount. Section 5. Optional Redemption. The Company may redeem at any time on or after September 15, 2000, all or any portion of the Securities outstanding at the following redemption prices expressed as a percentage of the principal amount thereof, if the Securities are redeemed during the 12-month period beginning September 15, of the following years: Year Percentage 2000................................................ 102.86% 2001................................................ 102.14% 2002................................................ 101.43% 2003................................................ 100.71% 2004................................................ 100% Section 6. Redemption or Repurchase at Option of Holder. If there is a Change in Control (as defined in the Indenture), the Company will be required to offer to A1-4 053113\1008\02764\979QGT85.OTH purchase on the Change in Control Payment Date (as defined in the Indenture) all outstanding Notes at 100% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase. Holders whose Notes are subject to an offer to purchase will receive an offer to purchase from the Company prior to any related Change in Control Payment Date and may elect to have their Notes purchased by completing the form entitled "Option of Holder to Elect Purchase" appearing below. Section 7. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 45 days before the redemption date to each Holder to be redeemed at its registered address. Notes may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption. Section 8. Conversion. Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, at any time on or after 270 days after the Issue Date and on or before the maturity, to convert the principal hereof or any portion of such principal that is $1,000 or a multiple thereof, into, at the Company's option, (a) cash in an amount equal to the Current Market Price, as of the conversion date, of the Common Stock to which the principal would otherwise be converted, or (b) that number of shares of the Company's Common Stock (as such shares shall then be constituted) obtained by dividing the principal amount of this Note or portion thereof to be converted by the conversion price of $38.50, or such conversion price as adjusted from time to time as provided in the Indenture or (c) a combination of cash and Common Stock in proportions determined by the Company in its sole discretion; provided, however, that the Company's option to convert the principal into cash or into a combination of cash and Common Stock, shall terminate at the close of business on the date the Company's charter is amended to increase the number of shares of authorized Common Stock to at least that number of shares sufficient to reserve for the conversion of all the Notes. The right to convert with respect to any Security or portion of a Security that shall be called for redemption or delivered for repurchase, shall terminate at the close of business on the date fixed for redemption of such Security or portion of a Security or the second trading day preceding a Change in Control Payment Date, as the case may be, unless the Company shall default in payment due upon redemption or repurchase thereof. No adjustments in respect of interest or dividends will be made upon any conversion; provided, however, that if the Note shall be surrendered for conversion during the period from the close of business on any record date for the payment of interest to the opening of business on the following interest payment date, this Note (unless it or the portion being converted shall have been called for redemption on a date in such period) must be accompanied by an amount, in funds acceptable to the Company, equal to the interest payable on such interest payment date on the principal amount being converted. No fractional shares will be issued upon any conversion, but an adjustment in cash shall be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted his Notes to Common A1-5 053113\1008\02764\979QGT85.OTH Stock, and only to the extent such Notes are to have been converted to Common Stock under the Indenture. The conversion price is subject to adjustment in accordance with Section 10.5 of the Indenture. Section 9. Subordination. The Securities are subordinated to Senior Indebtedness (as defined in the Indenture). To the extent provided in the Indenture, Senior Indebtedness must be paid before the Securities may be paid either by the Company or any guarantor of Obligations under this Indenture and the Note. The Company agrees, and each Holder by accepting a Security agrees, to the subordination provisions contained in the Indenture and authorizes the Trustee to give effect to such provisions, and each Holder appoints the Trustee his attorney-in-fact for any and all such purposes. This Note shall be pari passu, in all respects, with the Existing Debentures (as defined in the Indenture), except that the Existing Debentures have the benefit of guarantees by the Company's Subsidiaries. Section 10. Denominations, Transfer, Exchange. The Notes are initially issued in global form. The global Note represents such of the outstanding Securities as shall be specified therein or endorsed thereon in accordance with the Indenture. The definitive Securities are in registered form without coupons in denominations of $1,000 and whole multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not exchange or register the transfer of any Note or portion of an Note selected for redemption. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed. Section 11. Persons Deemed Owners. Before due presentment to the Trustee for registration of the transfer of this Note, the Trustee, any Agent and the Company may deem and treat the person in whose name this Note is registered as its absolute owner for the purpose of receiving payment of principal of and interest on this Note and for all other purposes whatsoever, whether or not this Note is overdue, and neither the Trustee, any Agent nor the Company shall be affected by notice to the contrary. The registered holder of an Note shall be treated as its owner for all purposes. Section 12. Amendments and Waivers. Subject to certain exceptions, the Indenture or the Securities may be amended with the consent of the Holders of at least a majority in principal amount of the then outstanding Securities, and any existing default (except a payment default) may be waived with the consent of the holders of a majority in principal amount of the then outstanding Securities. Without the consent of any Holder, the Indenture or the Securities may be amended to cure any ambiguity, defect or inconsistency, to provide for assumption of Company obligations to Holders, to make any change that does not adversely affect the rights of any Holder, to provide for any uncertificated Notes in addition to certificated Notes, or to comply with requirements of the Commission in order to effect or maintain the qualification of the Indenture under the TIA. A1-6 053113\1008\02764\979QGT85.OTH Section 13. Defaults and Remedies.

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare all the Securities to be due and payable immediately, except that in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Securities become due and payable immediately without further action or notice and all outstanding Securities, and all Obligations and Claims with respect thereto, become immediately due and payable. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee. Section 14. Trustee Dealings with Company. The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee; provided, however, that if the Trustee acquires any conflicting interest as described in the Trust Indenture Act, it must eliminate such conflict or resign. Section 15. No Recourse Against Others. No director, officer, employee, agent, manager, stockholder or other Affiliates of the Company shall have any liability for any obligations of the Company under the Securities, the Indenture, or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. Section 16. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. Section 17. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST = Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). Section 18. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP A1-7 053113\1008\02764\979QGT85.OTH numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification number placed thereon. Section 19. Additional Rights of Holders of Transfer Restricted Securities. In addition to the rights provided to Holders of Securities under the Indenture, Holders of Transferred Restricted Securities shall have all the rights set forth in the Registration Rights Agreement referred to in the Indenture and certain other agreements executed and delivered in connection therewith.

Section 6. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 45 days before the redemption date to each Holder to be redeemed at its registered address. Notes may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption. Section 7. Conversion. Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, at any time on or after 270 days after the Issue Date and on or before the maturity, to convert the principal hereof or any portion of such principal that is $1,000 or a multiple thereof, into, at the Company's option, (a) cash in an amount equal to the Current Market Price, as of the conversion date, of the Common Stock to which the principal would otherwise be converted, or (b) that number of shares of the Company's Common Stock (as such shares shall then be constituted) obtained by dividing the principal amount of this Note or portion thereof to be converted by the conversion price of $38.50, or such conversion price as adjusted from time to time as provided in the Indenture or (c) a combination of cash and Common Stock in proportions determined by the Company in its sole discretion; provided, however, that the Company's option to convert the principal into cash or into a combination of cash and Common Stock, shall terminate at the close of business on the date the Company's charter is amended to increase the number of shares of 053113\1008\02764\979QGT85.OTH A2-5 authorized Common Stock to at least that number of shares sufficient to reserve for the conversion of all the Notes. The right to convert with respect to any Security or portion of a Security that shall be called for redemption or delivered for repurchase, shall terminate at the close of business on the date fixed for redemption of such Security or portion of a Security or the second trading day preceding a Change in Control Payment Date, as the case may be, unless the Company shall default in payment due upon redemption or repurchase thereof. No adjustments in respect of interest or dividends will be made upon any conversion; provided, however, that if the Note shall be surrendered for conversion during the period from the close of business on any record date for the payment of interest to the opening of business on the following interest payment date, this Note (unless it or the portion being converted shall have been called for redemption on a date in such period) must be accompanied by an amount, in funds acceptable to the Company, equal to the interest payable on such interest payment date on the principal amount being converted. No fractional shares will be issued upon any conversion, but an adjustment in cash shall be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted his Notes to Common Stock, and only to the extent such Notes are to have been converted to Common Stock under the Indenture. The conversion price is subject to adjustment in accordance with Section 10.5 of the Indenture. Section 8. Subordination. The Securities are subordinated to Senior Indebtedness (as defined in the Indenture). To the extent provided in the Indenture, Senior Indebtedness must be paid before the Securities may be paid either by the Company or any guarantor of Obligations under this Indenture and the Note. The Company agrees, and each Holder by accepting a Security agrees, to the subordination provisions contained in the Indenture and authorizes the Trustee to give effect to such provisions, and each Holder appoints the Trustee his attorney-in-fact for any and all such purposes. This Note shall be pari passu, in all respects, with the Existing Debentures (as defined in the Indenture), except that the Existing Debentures have the benefit of guarantees by the Company's Subsidiaries. Section 9. Denominations, Transfer, Exchange. The Notes are initially issued in global form. The global Note represents such of the outstanding Securities as shall be specified therein or endorsed thereon in accordance with the Indenture.

The Registrar need not exchange or register the transfer of any Note or portion of an Note selected for redemption. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed. 053113\1008\02764\979QGT85.OTH A2-6 Section 10.

Before due presentment to the Trustee for registration of the transfer of this Note, the Trustee, any Agent and the Company may deem and treat the person in whose name this Note is registered as its absolute owner for the purpose of receiving payment of principal of and interest on this Note and for all other purposes whatsoever, whether or not this Note is overdue, and neither the Trustee, any Agent nor the Company shall be affected by notice to the contrary. The registered holder of an Note shall be treated as its owner for all purposes. Section 11. Amendments and Waivers. Subject to certain exceptions, the Indenture or the Securities may be amended with the consent of the Holders of at least a majority in principal amount of the then outstanding Securities, and any existing default (except a payment default) may be waived with the consent of the holders of a majority in principal amount of the then outstanding Securities. Without the consent of any Holder, the Indenture or the Securities may be amended to cure any ambiguity, defect or inconsistency, to provide for assumption of Company obligations to Holders, to make any change that does not adversely affect the rights of any Holder, to provide for any uncertificated Notes in addition to certificated Notes, or to comply with requirements of the Commission in order to effect or maintain the qualification of the Indenture under the TIA. Section 12. Defaults and Remedies. Events of default include: default in payment of interest on the Securities for 30 days; default in payment of principal of or premium on the Securities when due; failure by the Company for 60 days after notice to it to comply with its agreements in the Indenture or the Securities; defaults under and acceleration before express maturity of certain other Indebtedness that aggregates $25,000,000 or more; certain final judgments which remain undischarged if the aggregate of all such judgments exceeds $25,000,000 or more; certain final judgments which remain undischarged if the aggregate of all such judgments exceeds $25,000,000; and certain events of bankruptcy or insolvency. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare all the Securities to be due and payable immediately, except that in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Securities become due and payable immediately without further action or notice and all outstanding Securities, and all Obligations and Claims with respect thereto, become immediately due and payable. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee. Section 13. Trustee Dealings with Company. The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee; provided, however, that if the Trustee acquires any conflicting interest as described in the Trust Indenture Act, it must eliminate such conflict or resign. 053113\1008\02764\979QGT85.OTH A2-7 Section 14. No Recourse Against Others. No director, officer, employee, agent, manager, stockholder or other Affiliates of the Company shall have any liability for any obligations of the Company under the Securities, the Indenture, or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. Section 15. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. Section 16. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST = Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). Section 17. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification number placed thereon. Section 18. Additional Rights of Holders of Transfer Restricted Securities. In addition to the rights provided to Holders of Securities under the Indenture, Holders of Transferred Restricted Securities shall have all the rights set forth in the Registration Rights Agreement referred to in the Indenture and certain other agreements executed and delivered in connection therewith.
