Section 1.4. Acts of Holders; Record Dates. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Agent and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement and (subject to Section 7.1) conclusive in favor of the Agent and the Company, if made in the manner provided in this Section. 14 22 (b) The fact and date of the execution by any Person of any such instrument or writing may be proved in any manner which the Agent deems sufficient. (c) The ownership of Securities shall be proved by the Income PRIDES Register or the Growth PRIDES Register, as the case may be. (d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Certificate shall bind every future Holder of the same Certificate and the Holder of every Certificate issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Certificate. (e) The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Agreement to be given, made or taken by Holders of Securities. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite number of Outstanding Securities on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite number of Outstanding Securities on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Agent in writing and to each Holder of Securities in the manner set forth in Section 1.6. 15 23 With respect to any record date set pursuant to this Section, the Company may designate any date as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the Agent in writing, and to each Holder of Securities in the manner set forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the Company shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. Section 1.5. Notices. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Agreement to be made upon, given or furnished to, or filed with, (1) the Agent by any Holder or by the Company shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, to the Agent at One First National Plaza, Suite 0126, Chicago, Illinois 60670-0126, Attention: Corporate Trust Services Division, or at any other address previously furnished in writing by the Agent to the Holders and the Company, or (2) the Company by the Agent or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, to the Company at 500 Griswold Street, Detroit, Michigan 48226, Attention: Treasurer, or at any other address previously furnished in writing to the Agent by the Company. 16 24 (3) the Collateral Agent by the Agent, the Company or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, addressed to the Collateral Agent at The Chase Manhattan Bank, 450 W. 33rd Street, 15th Floor, New York, New York 10001, Attention: Corporate Trust Trustee Administration, or at any other address previously furnished in writing by the Collateral Agent to the Agent, the Company and the Holders; or (4) the Institutional Trustee by the Company shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, addressed to the Institutional Trustee at Rodney Sq. North, 1100 N. Market Street, Wilmington, Delaware 19890, Attention: Corporate Trustee Administration, or at any other address previously furnished in writing by the Institutional Trustee to the Company; or (5) the Indenture Trustee by the Company shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, addressed to the Indenture Trustee at NBD Bank, 611 Woodward Avenue, Detroit, MI 48226, Attention: Corporate Trust Administration, or at any other address previously furnished in writing by the Indenture Trustee to the Company. Section 1.6. Notice to Holders; Waiver. Where this Agreement provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at its address as it appears in the applicable Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the 17 25 failure to mail such notice, nor any defect in any notice so mailed to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Agent, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Agent shall constitute a sufficient notification for every purpose hereunder. Section 1.7. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. Section 1.8. Successors and Assigns. All covenants and agreements in this Agreement by the Company shall bind its successors and assigns, whether so expressed or not. Section 1.9. Separability Clause. In case any provision in this Agreement or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions hereof and thereof shall not in any way be affected or impaired thereby. Section 1.10. Benefits of Agreement. Nothing in this Agreement or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefits or any legal or equitable right, remedy or claim under this Agreement. The Holders from time to time shall be beneficiaries of this Agreement and 18 26 shall be bound by all of the terms and conditions hereof and of the Securities evidenced by their Certificates by their acceptance of delivery of such Certificates. Section 1.11. Governing Law. This Agreement and the Securities shall be governed by and construed in accordance with the laws of the State of New York. Section 1.12. Legal Holidays. In any case where any Payment Date shall not be a Business Day, then (notwithstanding any other provision of this Agreement or the Income PRIDES Certificates or the Growth PRIDES Certificates) payment of the Contract Adjustment Payments shall not be made on such date, but such payments shall be made on the next succeeding Business Day with the same force and effect as if made on such Payment Date, provided that no interest shall accrue or be payable by the Company or any Holder for the period from and after any such Payment Date, except that, if such next succeeding Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day with the same force and effect as if made on such Payment Date. In any case where any Purchase Contract Settlement Date shall not be a Business Day, then (notwithstanding any other provision of this Agreement, the Income PRIDES Certificates or the Growth PRIDES Certificates), the Purchase Contracts shall not be performed on such date, but the Purchase Contracts shall be performed on the next preceding Business Day with the same force and effect as if performed on such Purchase Contract Settlement Date. Section 1.13. Counterparts. This Agreement may be executed in any number of counterparts by the parties hereto on separate counterparts, each of which, when so executed and delivered, shall be deemed an original, but all such counterparts shall together constitute one and the same instrument. 19 27 Section 1.14.

ARTICLE III The Securities Section 3.1. Title and Terms; Denominations. The aggregate number of Income PRIDES evidenced by Certificates authenticated, executed on behalf of the 21 29 Holders and delivered hereunder is limited to 2,645,000 except for Certificates authenticated, executed and delivered upon registration of transfer of, in exchange for, or in lieu of, other Certificates pursuant to Section 3.4, 3.5, 3.10, 3.13, 3.14, 5.9 or 8.5. The Certificates shall be issuable only in registered form and only in denominations of a single Income PRIDES or Growth PRIDES and any integral multiple thereof. Section 3.2. Rights and Obligations Evidenced by the Certificates. Each Income PRIDES Certificate shall evidence the number of Income PRIDES specified therein, with each such Income PRIDES representing the ownership by the Holder thereof of a beneficial interest in Preferred Security with a principal amount equal to the Stated Amount, subject to the Pledge of such Preferred Security by such Holder pursuant to the Pledge Agreement, and the rights and obligations of the Holder thereof and the Company under one Purchase Contract.

Prior to the purchase of shares of Common Stock under the Purchase Contracts, such Purchase Contracts shall not entitle the Holders of Income PRIDES Certificates to any of the rights of a holder of shares of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or to consent or to receive notice as stockholders in respect of the meetings of stockholders or for the election of directors of the Company or for any other matter, or any other rights whatsoever as stockholders of the Company.

Prior to the purchase, if any, of shares of Common Stock under the Purchase Contracts, such Growth PRIDES Certificates shall not entitle the Holders of Growth PRIDES Certificates to any of the rights of a holder of shares of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or to consent or to receive notice as stockholders in respect of the meetings of stockholders or for the election of directors of the Company or for any other matter, or any other rights whatsoever as stockholders of the Company. Section 3.3. Execution, Authentication, Delivery and Dating. Subject to the provisions of Sections 3.13 and 3.14 hereof, upon the execution and delivery of this Agreement, and at any time and from time to time thereafter, the Company may deliver Certificates executed by the Company to the Agent for authentication, execution on behalf of the Holders and delivery, together with its Issuer Order for authentication of such Certificates, and the Agent in accordance with such Issuer Order shall authenticate, execute on behalf of the Holder and deliver such Certificates. The Certificates shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its President or one of its Vice Presidents, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Certificates may be manual or facsimile. Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates. 23 31 No Purchase Contract evidenced by a Certificate shall be valid until such Certificate has been executed on behalf of the Holder by the manual signature of an authorized signatory of the Agent, as such Holder's attorney-in-fact. Such signature by an authorized signatory of the Agent shall be conclusive evidence that the Holder of such Certificate has entered into the Purchase Contracts evidenced by such Certificate. Each Certificate shall be dated the date of its authentication. No Certificate shall be entitled to any benefit under this Agreement or be valid or obligatory for any purpose unless there appears on such Certificate a certificate of authentication substantially in the form provided for herein executed by an authorized signatory of the Agent by manual signature, and such certificate upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. Section 3.4. Temporary Certificates. Pending the preparation of definitive Certificates, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holders, and deliver, in lieu of such definitive Certificates, temporary Certificates which are in substantially the form set forth in Exhibit A or Exhibit B hereto, as the case may be, with such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as may be required by the rules of any securities exchange on which the Income PRIDES or Growth PRIDES are listed, or as may, consistently herewith, be determined by the officers of the Company executing such Certificates, as evidenced by their execution of the Certificates. If temporary Certificates are issued, the Company will cause definitive Certificates to be prepared without unreasonable delay. After the preparation of definitive Certificates, the temporary Certificates shall be exchangeable for definitive Certificates upon surrender of the temporary Certificates at the Corporate Trust Office, at the expense of the Company and without charge to the 24 32 Holder. Upon surrender for cancellation of any one or more temporary Certificates, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holder, and deliver in exchange therefor, one or more definitive Certificates of like tenor authorized denominations and evidencing a like number of Income PRIDES or Growth PRIDES, as the case may be, as the temporary Certificate or Certificates so surrendered. Until so exchanged, the temporary Certificates shall in all respects evidence the same benefits and the same obligations with respect to the Income PRIDES or Growth PRIDES, as the case may be, evidenced thereby as definitive Certificates. Section 3.5. Registration; Registration of Transfer and Exchange. The Agent shall keep at the Corporate Trust Office a register (the "Income PRIDES Register") in which, subject to such reasonable regulations as it may prescribe, the Agent shall provide for the registration of Income PRIDES Certificates and of transfers of Income PRIDES Certificates (the Agent, in such capacity, the "Income PRIDES Registrar") and a Register (the "Growth PRIDES Register") in which, subject to such reasonable regulations as it may prescribe, the Agent shall provide for the registration of the Growth PRIDES Certificates following Collateral Substitutions and transfers of Growth PRIDES Certificates (the Agent, in such capacity, the "Growth PRIDES Registrar"). Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the designated transferee or transferees, and deliver, in the name of the designated transferee or transferees, one or more new Certificates of any authorized denominations, like tenor, and evidencing a like number of Income PRIDES or Growth PRIDES, as the case may be. At the option of the Holder, Certificates may be exchanged for other Certificates, of any authorized denominations and evidencing a like number of Income PRIDES or Growth PRIDES, as the case may be, upon surrender of the Certificates to be exchanged at the Corporate Trust Office. Whenever any Certificates are so surren- 25 33 dered for exchange, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holder, and deliver the Certificates which the Holder making the exchange is entitled to receive. All Certificates issued upon any registration of transfer or exchange of a Certificate shall evidence the ownership of the same number of Income PRIDES or Growth PRIDES, as the case may be, and be entitled to the same benefits and subject to the same obligations, under this Agreement as the Income PRIDES or Growth PRIDES, as the case may be, evidenced by the Certificate surrendered upon such registration of transfer or exchange. Every Certificate presented or surrendered for registration of transfer or for exchange shall (if so required by the Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Agent duly executed, by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of a Certificate, but the Company and the Agent may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Certificates, other than any exchanges pursuant to Sections 3.6 and 8.5 not involving any transfer. Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Agent, and the Agent shall not be obligated to authenticate, execute on behalf of the Holder and deliver any Certificate presented or surrendered for registration of transfer or for exchange on or after the Purchase Contract Settlement Date or the Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Agent shall (i) if the Purchase Contract Settlement Date has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Securities evidenced by such Certificate, (ii) in the case of Income PRIDES, if a 26 34 Termination Event shall have occurred prior to the Purchase Contract Settlement Date, transfer the aggregate Stated Amount of the Preferred Securities evidenced thereby, or (iii) in the case of Growth PRIDES, if a Termination Event shall have occurred prior to the Purchase Contract Settlement Date, transfer the Treasury Securities evidenced thereby, in each case subject to the applicable conditions and in accordance with the applicable provisions of Article Five hereof. Section 3.6. Book-Entry Interests. The Certificates, on original issuance, will be issued in the form of one or more, fully registered Global Certificates, to be delivered to the Depositary by, or on behalf of, the Company. Such Global Certificate shall initially be registered on the books and records of the Company in the name of Cede & Co., the nominee of the Depositary, and no Beneficial Owner will receive a definitive Certificate representing such Beneficial Owner's interest in such Global Certificate, except as provided in Section 3.9. The Agent shall enter into an agreement with the Depositary if so requested by the Company. Unless and until definitive, fully registered Certificates have been issued to Beneficial Owners pursuant to Section 3.9: (a) the provisions of this Section 3.6 shall be in full force and effect; (b) the Company shall be entitled to deal with the Clearing Agency for all purposes of this Agreement (including the payment of Contract Adjustment Payments and receiving approvals, votes or consents hereunder) as the Holder of the Securities and the sole holder of the Global Certificate(s) and shall have no obligation to the Beneficial Owners; (c) to the extent that the provisions of this Section 3.6 conflict with any other provisions of this Agreement, the provisions of this Section 3.6 shall control; and (d) the rights of the Beneficial Owners shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such Beneficial Owners and the Clearing Agency 27 35 and/or the Clearing Agency Participants. The Clearing Agency will make book entry transfers among Clearing Agency Participants and receive and transmit payments of Contract Adjustment Payments to such Clearing Agency Participants. Section 3.7. Notices to Holders. Whenever a notice or other communication to the Holders is required to be given under this Agreement, the Company or the Company's agent shall give such notices and communications to the Holders and, with respect to any Securities registered in the name of a Clearing Agency or the nominee of a Clearing Agency, the Company or the Company's agent shall, except as set forth herein, have no obligations to the Beneficial Owners. Section 3.8. Appointment of Successor Clearing Agency. If any Clearing Agency elects to discontinue its services as securities depositary with respect to the Securities, the Company may, in its sole discretion, appoint a successor Clearing Agency with respect to the Securities. Section 3.9. Definitive Certificates. If (i) a Clearing Agency elects to discontinue its services as securities depositary with respect to the Securities and a successor Clearing Agency is not appointed within 90 days after such discontinuance pursuant to Section 3.8, (ii) the Company elects to terminate the book-entry system through the Clearing Agency with respect to the Securities, or (iii) there shall have occurred and be continuing a default by the Company in respect of its obligations under one or more Purchase Contracts, then upon surrender of the Global Certificates representing the Book-Entry Interests with respect to the Securities by the Clearing Agency, accompanied by registration instructions, the Company shall cause definitive Certificates to be delivered to Beneficial Owners in accordance with the instructions of the Clearing Agency. The Company shall not be liable for any delay in delivery of such instructions and may conclusively rely on and shall be protected in relying on, such instructions. 28 36 Section 3.10. Mutilated, Destroyed, Lost and Stolen Certificates. If any mutilated Certificate is surrendered to the Agent, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holder, and deliver in exchange therefor, a new Certificate, evidencing the same number of Income PRIDES or Growth PRIDES, as the case may be, and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Agent (i) evidence to their satisfaction of the destruction, loss or theft of any Certificate, and (ii) such security or indemnity as may be required by them to hold each of them and any agent of any of them harmless, then, in the absence of notice to the Company or the Agent that such Certificate has been acquired by a bona fide purchaser, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed, lost or stolen Certificate, a new Certificate, evidencing the same number of Income PRIDES or Growth PRIDES, as the case may be, and bearing a number not contemporaneously outstanding. Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Agent, and the Agent shall not be obligated to authenticate, execute on behalf of the Holder, and deliver to the Holder, a Certificate on or after the Purchase Contract Settlement Date or the Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Agent shall (i) if the Purchase Contract Settlement Date has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Securities evidenced by such Certificate, or (ii) if a Termination Event shall have occurred prior to the Purchase Contract Settlement Date, transfer the Preferred Securities or the Treasury Securities, as the case may be, evidenced thereby, in each case subject to the applicable conditions and in accordance with the applicable provisions of Article Five hereof. 29 37 Upon the issuance of any new Certificate under this Section, the Company and the Agent may require the payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Agent) connected therewith. Every new Certificate issued pursuant to this Section in lieu of any destroyed, lost or stolen Certificate shall constitute an original additional contractual obligation of the Company and of the Holder in respect of the Security evidenced thereby, whether or not the destroyed, lost or stolen Certificate (and the Securities evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits and be subject to all the obligations of this Agreement equally and proportionately with any and all other Certificates delivered hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates. Section 3.11. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Company and the Agent, and any agent of the Company or the Agent, may treat the Person in whose name such Certificate is registered as the owner of the Income PRIDES or Growth PRIDES evidenced thereby, for the purpose of receiving distributions on the Preferred Securities, receiving payments of Contract Adjustment Payments, performance of the Purchase Contracts and for all other purposes whatsoever, whether or not any distributions on the Preferred Securities or the Contract Adjustment Payments payable in respect of the Purchase Contracts constituting a part of the Income PRIDES or Growth PRIDES evidenced thereby shall be overdue and notwithstanding any notice to the contrary, and neither the Company nor the Agent, nor any agent of the Company or the Agent, shall be affected by notice to the contrary. Notwithstanding the foregoing, with respect to any Global Certificate, nothing herein shall prevent the Company, the Agent or any agent of the Company or the Agent, from giving effect to any written certification, 30 38 proxy or other authorization furnished by any Clearing Agency (or its nominee), as a Holder, with respect to such Global Certificate or impair, as between such Clearing Agency and owners of beneficial interests in such Global Certificate, the operation of customary practices governing the exercise of rights of such Clearing Agency (or its nominee) as Holder of such Global Certificate. Section 3.12. Cancellation. All Certificates surrendered for delivery of shares of Common Stock on or after the Purchase Contract Settlement Date, upon the transfer of Preferred Securities or Treasury Securities, as the case may be, after the occurrence of a Termination Event or pursuant to an Early Settlement, or upon the registration of a transfer or exchange of a Security, or a Collateral Substitution or the re-establishment of an Income PRIDES shall, if surrendered to any Person other than the Agent, be delivered to the Agent and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Agent for cancellation any Certificates previously authenticated, executed and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Certificates so delivered shall, upon Issuer Order, be promptly cancelled by the Agent. No Certificates shall be authenticated, executed on behalf of the Holder and delivered in lieu of or in exchange for any Certificates cancelled as provided in this Section, except as expressly permitted by this Agreement. All cancelled Certificates held by the Agent shall be destroyed by the Agent unless otherwise directed by Issuer Order. If the Company or any Affiliate of the Company shall acquire any Certificate, such acquisition shall not operate as a cancellation of such Certificate unless and until such Certificate is delivered to the Agent cancelled or for cancellation. Section 3.13. Substitution of Securities. A Holder may separate Preferred Securities from the related Purchase Contracts in respect of an Income PRIDES by substituting for such Preferred Securities, Treasury Securities in an aggregate principal amount equal to the aggregate Stated Amount of such Preferred Securities (a "Collateral Substitution") at any time from and after the 31 39 date of this Agreement and on or prior to the second Business Day immediately preceding the Purchase Contract Settlement Date by (a) depositing with the Collateral Agent Treasury Securities having an aggregate principal amount equal to the aggregate Stated Amount of the Preferred Securities comprising part of such Income PRIDES and (b) transferring the related Income PRIDES to the Agent accompanied by a notice to the Agent, substantially in the form of Exhibit D hereto, stating that the Holder has transferred the relevant amount of Treasury Securities to the Collateral Agent and requesting that the Agent instruct the Collateral Agent to release the Preferred Securities underlying such Income PRIDES, whereupon the Agent shall promptly give such instruction to the Collateral Agent, substantially in the form of Exhibit C hereto. Upon receipt of the Treasury Securities described in clause (a) above and the instruction described in clause (b) above, in accordance with the terms of the Pledge Agreement, the Collateral Agent will release to the Agent, on behalf of the Holder, Preferred Securities having a corresponding aggregate Stated Amount from the Pledge, free and clear of the Company's security interest therein, and upon receipt thereof the Agent shall promptly: (i) cancel the related Income PRIDES; (ii) transfer the Preferred Securities to the Holder; and (iii) authenticate, execute on behalf of such Holder and deliver a Growth PRIDES Certificate executed by the Company in accordance with Section 3.3 evidencing the same number of Purchase Contracts as were evidenced by the cancelled Income PRIDES Certificates. Holders who elect to separate the Preferred Security from the related Purchase Contract and to substitute Treasury Securities for such Preferred Securities shall be responsible for any fees or expenses payable to the Collateral Agent for its services as Collateral Agent in respect of the substitution, and the Company shall not be responsible for any such fees or expenses. Holders may make Collateral Substitutions only in integral multiples of 20 Income PRIDES. 32 40 In the event a Holder making a Collateral Substitution pursuant to this Section 3.13 fails to effect a book-entry transfer of the Income PRIDES or fails to deliver an Income PRIDES Certificate(s) to the Agent after depositing Treasury Securities with the Collateral Agent, the Preferred Security constituting a part of such Income PRIDES, and any distributions on such Preferred Security, shall be held in the name of the Agent or its nominee in trust for the benefit of such Holder, until such Income PRIDES is so transferred or the Income PRIDES Certificate is so delivered, as the case may be, or, with respect to an Income PRIDES Certificate, such Holder provides satisfactory evidence that such Income PRIDES Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Agent and the Company. Except as described in this Section 3.13, for so long as the Purchase Contract underlying an Income PRIDES remains in effect, such Income PRIDES shall not be separable into its constituent parts, and the rights and obligations of the Holder in respect of the Preferred Security and Purchase Contract comprising such Income PRIDES may be acquired, and may be transferred and exchanged, only as an Income PRIDES. Section 3.14. Reestablishment of Income PRIDES. A Holder of a Growth PRIDES may at any time on or prior to the second Business Day immediately preceding the Purchase Contract Settlement Date, recreate Income PRIDES by (a) depositing with the Collateral Agent Preferred Securities having an aggregate Stated Amount equal to the aggregate principal amount of the Treasury Securities comprising part of the Growth PRIDES to the Collateral Agent and (b) transferring the related Growth PRIDES to the Agent accompanied by a notice to the Agent, substantially in the form of Exhibit D hereto, stating that the Holder has transferred the relevant amount of Preferred Securities to the Collateral Agent and requesting that the Agent instruct the Collateral Agent to release the Treasury Securities underlying such Growth PRIDES, whereupon the Agent shall promptly give such instruction to the Collateral Agent, substantially in the form of Exhibit C hereto. Upon receipt of the Preferred Securities described in clause (a) above and the instruction described in clause (b) above, in accordance with the 33 41 terms of the Pledge Agreement, the Collateral Agent will effect the release of the Treasury Securities having a corresponding aggregate principal amount from the Pledge to the Agent free and clear of the Company's security interest therein, and upon receipt thereof the Agent shall promptly: (i) cancel the related Growth PRIDES; (ii) transfer the Treasury Securities to the Holder; and (iii) authenticate, execute on behalf of such Holder and deliver an Income PRIDES Certificate executed by the Company in accordance with Section 3.3 evidencing the same number of Purchase Contracts as were evidenced by the cancelled Growth PRIDES. Holders of Growth PRIDES may reestablish Income PRIDES only in integral multiples of 20 Income PRIDES for each Growth PRIDES. Except as provided in this Section 3.14, for so long as the Purchase Contract underlying a Growth PRIDES remains in effect, such Growth PRIDES shall not be separable into its constituent parts and the rights and obligations of the Holder of such Growth PRIDES in respect of the Treasury Security and Purchase Contract comprising such Growth PRIDES may be acquired, and may be transferred and exchanged only as a Growth PRIDES. Section 3.15. Transfer of Collateral upon Occurrence of Termination Event. Upon the occurrence of a Termination Event and the transfer to the Agent of the Preferred Securities or the Treasury Securities, as the case may be, underlying the Income PRIDES and the Growth PRIDES, respectively, pursuant to the terms of the Pledge Agreement, the Agent shall request transfer instructions with respect to such Preferred Securities and/or Treasury Securities, as the case may be, from each Holder by written request mailed to such Holder at its address as it appears in the Income PRIDES Register or the Growth PRIDES Register, as the case may be. Upon book-entry transfer of the Income PRIDES or Growth PRIDES or delivery of an Income PRIDES Certificate or Growth PRIDES Certificate to the Agent 34 42 with such transfer instructions, the Agent shall transfer the Preferred Securities or Treasury Securities underlying such Income PRIDES or Growth PRIDES, as the case may be, to such Holder by book-entry transfer, or other appropriate procedures, in accordance with such instructions. In the event a Holder of Income PRIDES or Growth PRIDES fails to effect such transfer or delivery, the Preferred Securities or Treasury Securities underlying such Income PRIDES or Growth PRIDES, as the case may be, and any distributions thereon, shall be held in the name of the Agent or its nominee in trust for the benefit of such Holder, until such Income PRIDES or Growth PRIDES are transferred or the Income PRIDES Certificate or Growth PRIDES Certificate is surrendered or such Holder provides satisfactory evidence that such Income PRIDES Certificate or Growth PRIDES Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Agent and the Company. Section 3.16. No Consent to Assumption. Each Holder of a Security, by acceptance thereof, shall be deemed expressly to have withheld any consent to the assumption under Section 365 of the Bankruptcy Code or otherwise, of the Purchase Contract by the Company or its trustee in the event that the Company becomes the debtor under the Bankruptcy Code. ARTICLE IV The Preferred Securities Section 4.1. Payment of Distribution; Rights to Distributions Preserved. A distribution on any Preferred Security which is paid on any Payment Date shall, subject to receipt thereof by the Agent from the Collateral Agent as provided by the terms of the Pledge Agreement, be paid to the Person in whose name the Income PRIDES Certificate (or one or more Predecessor Income PRIDES Certificates) of which such Preferred Security is a part is registered at the close of business on the Record Date for such Payment Date. 35 43 Each Income PRIDES Certificate evidencing Preferred Securities delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of any other Income PRIDES Certificate shall carry the rights to distributions accrued and unpaid, and to accrue distributions, which were carried by the Preferred Securities underlying such other Income PRIDES Certificate. In the case of any Income PRIDES with respect to which Cash Settlement of the underlying Purchase Contract is effected on a Purchase Contract Settlement Date, or with respect to which Early Settlement of the underlying Purchase Contract is effected on an Early Settlement Date, or with respect to which a Collateral Substitution is effected on a date, after any Record Date and on or prior to the next succeeding Payment Date, distributions on the Preferred Securities underlying such Income PRIDES otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Cash Settlement or Early Settlement or Collateral Substitution, and such distributions shall, subject to receipt thereof by the Agent, be paid to the Person in whose name the Income PRIDES Certificate (or one or more Predecessor Income PRIDES Certificates) is registered at the close of business on the Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Income PRIDES with respect to which Cash Settlement or Early Settlement of the underlying Purchase Contract is effected on a Purchase Contract Settlement Date or an Early Settlement Date, as the case may be, or with respect to which a Collateral Substitution has been effected, distributions on the related Preferred Securities that would otherwise be payable after the Purchase Contract Settlement Date or Early Settlement Date shall not be payable hereunder to the Holder of such Income PRIDES; provided, however, that to the extent that such Holder continues to hold the separated Preferred Securities that formerly comprised a part of such Holder's Income PRIDES, such Holder shall be entitled to receive the distributions on such separated Preferred Securities. 36 44 Section 4.2. Notice and Voting. Under the terms of the Pledge Agreement, the Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Preferred Securities pledged with the Collateral Agent but only to the extent instructed by the Holders as described below. Upon receipt of notice of any meeting at which holders of Preferred Securities are entitled to vote or upon any solicitation of consents, waivers or proxies of holders of Preferred Securities, the Agent shall, as soon as practicable thereafter, mail to the Holders a notice (a) containing such information as is contained in the notice or solicitation, (b) stating that each Holder on the record date set by the Agent therefor (which, to the extent possible, shall be the same date as the record date for determining the holders of Preferred Securities entitled to vote) shall be entitled to instruct the Agent as to the exercise of the voting rights pertaining to the Preferred Securities underlying their Income PRIDES and (c) stating the manner in which such instructions may be given. Upon the written request of the Holders on such record date, the Agent shall endeavor insofar as practicable to vote or cause to be voted, in accordance with the instructions set forth in such requests, the maximum number of Preferred Securities as to which any particular voting instructions are received. In the absence of specific instructions from the Holder of an Income PRIDES, the Agent shall abstain from voting the Preferred Security underlying such Income PRIDES. The Company hereby agrees, if applicable, to solicit Holders to timely instruct the Agent in order to enable the Agent to vote such Preferred Securities or to cause such Preferred Securities to be voted, and the Trust shall covenant in the Declaration to take all action which may be deemed necessary by the Agent in order to enable the Agent to vote such Preferred Securities or to cause such Preferred Securities to be voted. Section 4.3. Tax Event; Investment Company Event. Upon the occurrence of a Tax Event or an Investment Company Event or a liquidation of the Trust, a principal amount of Junior Subordinated Debentures constituting the assets of the Trust and underlying the Preferred Securities equal to the aggregate Stated Amount of the Pledged Preferred Securities shall be delivered to the Collateral 37 45 Agent in exchange for the Pledged Preferred Securities. Thereafter, the Junior Subordinated Debentures will be held by the Collateral Agent in accordance with the terms of the Pledge Agreement to secure the obligations of each Holder of an Income PRIDES to purchase the Common Stock of the Company under the Purchase Contracts constituting a part of such Income PRIDES. Following the occurrence of a Tax Event, an Investment Company Event or a liquidation of the Trust, the Holders and the Collateral Agent shall have such security interests, rights and obligations with respect to the Junior Subordinated Debentures as the Holders and the Collateral Agent had in respect of the Preferred Securities subject to the Pledge thereof as provided in Articles II, III, IV, V and VI of the Pledge Agreement, and any reference herein to the Preferred Securities shall be deemed to be a reference to the Junior Subordinated Debentures. The Company may cause to be made in any Income PRIDES Certificates thereafter to be issued such change in phraseology and form (but not in substance) as may be appropriate to reflect the liquidation of the Trust and the substitution of Junior Subordinated Debentures for Preferred Securities as Collateral. ARTICLE V The Purchase Contracts Section 5.1. Purchase of Shares of Common Stock. Each Purchase Contract shall obligate the Holder of the related Security to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a price equal to the Stated Amount (the "Purchase Price"), a number of shares of Common Stock equal to the Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date, there shall have occurred a Termination Event, Cash Settlement or an Early Settlement with respect to the Security of which such Purchase Contract is a part. The "Settlement Rate" is equal to (a) if the Applicable Market Value (as defined below) is equal to or greater than $35.38 (the "Threshold Appreciation Price"), 1.4132 shares of Common Stock per Purchase Contract, (b) if the Applicable Market Value is less than the Threshold Appreciation Price, but is greater than $29, the number of shares of Common Stock equal to the Stated Amount 38 46 divided by the Applicable Market Value and (c) if the Applicable Market Value is less than or equal to $29, 1.7241 shares of Common Stock per Purchase Contract, in each case subject to adjustment as provided in Section 5.6 (and in each case rounded upward or downward to the nearest 1/10,000th of a share). As provided in Section 5.10, no fractional shares of Common Stock will be issued upon settlement of Purchase Contracts. The "Applicable Market Value" means the average of the Closing Prices per share of Common Stock on each of the twenty consecutive Trading Days ending on the second Trading Day immediately preceding the Purchase Contract Settlement Date. The "Closing Price" of the Common Stock on any date of determination means the closing sale price (or, if no closing price is reported, the last reported sale price) of the Common Stock on the New York Stock Exchange (the "NYSE") on such date or, if the Common Stock is not listed for trading on the NYSE on any such date, as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is so listed, or if the Common Stock is not so listed on a United States national or regional securities exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not so reported, the last quoted bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or, if such bid price is not available, the market value of the Common Stock on such date as determined by a nationally recognized independent investment banking firm retained for this purpose by the Company. A "Trading Day" means a day on which the Common Stock (A) is not suspended from trading on any national or regional securities exchange or association or over-the-counter market at the close of business and (B) has traded at least once on the national or regional securities exchange or association or over-the-counter market that is the primary market for the trading of the Common Stock. Each Holder of an Income PRIDES or a Growth PRIDES, by its acceptance thereof, irrevocably authorizes the Agent to enter into and perform the related Purchase Contract on its behalf as its attorney-in-fact, agrees to be bound by the terms and provisions thereof, covenants and agrees to perform its obligations under such Purchase Contracts, and consents to the provisions hereof, irrevo- 39 47 cably authorizes the Agent as its attorney-in-fact to enter into and perform the Pledge Agreement on its behalf as its attorney-in-fact, and consents to and agrees to be bound by the Pledge of the Preferred Securities or the Treasury Securities pursuant to the Pledge Agreement; provided that upon a Termination Event, the rights of the Holder of such Security under the Purchase Contract may be enforced without regard to any other rights or obligations. Each Holder of an Income PRIDES or a Growth PRIDES, by its acceptance thereof, further covenants and agrees, that, to the extent and in the manner provided in Section 5.4 and the Pledge Agreement, but subject to the terms thereof, payments in respect of the Stated Amount of the Preferred Securities or the Proceeds of the Treasury Securities on the Purchase Contract Settlement Date shall be paid by the Collateral Agent to the Company in satisfaction of such Holder's obligations under such Purchase Contract and such Holder shall acquire no right, title or interest in such payments. Upon registration of transfer of a Certificate, the transferee shall be bound (without the necessity of any other action on the part of such transferee), under the terms of this Agreement, the Purchase Contracts underlying such Certificate and the Pledge Agreement and the transferor shall be released from the obligations under this Agreement, the Purchase Contracts underlying the Certificates so transferred and the Pledge Agreement. The Company covenants and agrees, and each Holder of a Certificate, by its acceptance thereof, likewise covenants and agrees, to be bound by the provisions of this paragraph. Section 5.2. Contract Adjustment Payments. Subject to Section 5.3, the Company shall pay, on each Payment Date, the Contract Adjustment Payments payable in respect of each Purchase Contract to the Person in whose name a Certificate (or one or more Predecessor Certificates) is registered at the close of business on the Record Date next preceding such Payment Date. The Contract Adjustment Payments will be payable at the office of the Agent in The City of New York maintained for that purpose or, at the option of the Company, by check mailed to the address of the Person entitled thereto at such Person's address as it appears on the Income PRIDES Register or Growth PRIDES Register. 40 48 Upon the occurrence of a Termination Event, Contract Adjustment Payments shall cease to accrue in respect of any period from and after the date of such Termination Event (unless the Company defaults in the payment of accrued Contract Adjustment Payments). The Company's obligations to pay any accrued Contract Adjustment Payments shall be deemed to be fulfilled if the Company deposits with the Agent funds necessary to pay accrued Contract Adjustment Payments, in trust with irrevocable instructions and authorization that such funds shall be delivered to the Holders. Each Certificate delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of (including as a result of a Collateral Substitution or the re-establishment of an Income PRIDES) any other Certificate shall carry the rights to Contract Adjustment Payments accrued and unpaid, and to accrue Contract Adjustment Payments, which were carried by the Purchase Contracts underlying such other Certificates. In the case of any Security with respect to which Early Settlement of the underlying Purchase Contract is effected on an Early Settlement Date, after any Record Date and on or prior to the next succeeding Payment Date, Contract Adjustment Payments otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Early Settlement, and such Contract Adjustment Payments shall be paid to the Person in whose name the Certificate evidencing such Security (or one or more Predecessor Certificates) is registered at the close of business on such Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security with respect to which Early Settlement of the underlying Purchase Contract is effected on an Early Settlement Date, Contract Adjustment Payments that would otherwise be payable after the Early Settlement Date with respect to such Purchase Contract shall not be payable. The Company's obligations with respect to Contract Adjustment Payments are subordinate and junior in right of payment to all liabilities of the Company, other than the Yield Enhancement Payments payable by the Company in respect of its 8 3/4% PRIDES and the Company's guarantee of its subordinated debentures with which they rank pari passu. 41 49 Section 5.3. Deferral of Payment Dates For Contract Adjustment Payments. The Company shall have the right, at any time prior to the Purchase Contract Settlement Date, to defer the payment of any or all of the Contract Adjustment Payments otherwise payable on any Payment Date, but only if the Company shall give the Holders and the Agent written notice of its election to defer such payment (specifying the amount to be deferred) at least ten Business Days prior to the earlier of (i) the next succeeding Payment Date or (ii) the date the Company is required to give notice of the Record Date or Payment Date with respect to payment of such Contract Adjustment Payments to the New York Stock Exchange or other applicable self-regulatory organization or to Holders of the Securities, but in any event not less than two Business Days prior to such Record Date. Any Contract Adjustment Payments so deferred shall bear additional Contract Adjustment Payments thereon at the rate of 8% per annum (computed on the basis of 360 day year of twelve 30 day months), compounding on each succeeding Payment Date, until paid in full (such deferred installments of Contract Adjustment Payments together with the additional Contract Adjustment Payments accrued thereon, being referred to herein as the "Deferred Contract Adjustment Payments"). Deferred Contract Adjustment Payments shall be due on the next succeeding Payment Date except to the extent that payment is deferred pursuant to this Section. No Contract Adjustment Payments may be deferred to a date that is after the Purchase Contract Settlement Date or, with respect to any particular Purchase Contract, Early Settlement thereof. If the Purchase Contracts are terminated (upon the occurrence of a Termination Event, the Holder's right to receive Contract Adjustment Payments and Deferred Contract Adjustment Payments will terminate. In the event that the Company elects to defer the payment of Contract Adjustment Payments on the Purchase Contracts until the Purchase Contract Settlement Date, each Holder will receive on the Purchase Contract Settlement Date, in lieu of a cash payment, a number of shares of Common Stock (in addition to a number of shares of Common Stock equal to the Settlement Rate) equal to (x) the aggregate amount of Deferred Contract Adjustment Payments payable to a Holder divided by (y) the Applicable Market Value. 42 50 No fractional shares of Common Stock will be issued by the Company with respect to the payment of Deferred Contract Adjustment Payments on the Purchase Contract Settlement Date. In lieu of fractional shares otherwise issuable with respect to such payment of Deferred Contract Adjustment Payments, the Holder will be entitled to receive an amount in cash as provided in Section 5.10. In the event the Company exercises its option to defer the payment of Contract Adjustment Payments, then, until the Deferred Contract Adjustment Payments have been made, (a) the Company shall not declare or pay dividends on, make distributions with respect to, or redeem, purchase or acquire, or make a liquidation payment with respect to, any of its capital stock (other than (i) purchases or acquisitions of shares of Common Stock in connection with the satisfaction by the Company of its obligations under any employee benefit plans or the satisfaction by the Company of its obligations pursuant to any contract or security outstanding on the date of such event requiring the Company to purchase shares of Common Stock, (ii) as a result of a reclassification of the Company's capital stock or the exchange or conversion of one class or series of the Company's capital stock for another class or series of the Company's capital stock or (iii) the purchase of fractional interests in shares of the Company's capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged) or make any guarantee payments with respect to the foregoing), (b) the Company shall not make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any debt securities (including guarantees) issued by the Company that rank pari passu with such Contract Adjustment Payments and (c) the Company shall not make any guarantee payments with respect to the foregoing. Section 5.4. Payment of Purchase Price. (a) Unless a Holder settles the underlying Purchase Contract either through the early delivery of cash to the Purchase Contract Agent in the manner described in Section 5.9 or otherwise, the Purchase Price for the shares of Common Stock purchased pursuant to a Purchase Contract shall be paid by application of payments received by the Company on the Purchase Contract Settlement Date from the Collateral Agent pursuant to the Pledge Agreement, pay- 43 51 able at the office of the Collateral Agent in the City of New York maintained for such purpose, as follows: (i) A Holder may effect a "Cash Settlement" of a Purchase Contract by (A) providing the Agent with notice of its election to effect a Cash Settlement on or prior to 5:00 p.m., New York City time, on the second Business Day immediately preceding the Purchase Contract Settlement Date (B) concurrently making a payment of the Purchase Price to the Collateral Agent prior to 9:00 a.m., New York City time, on the Business Day immediately preceding the Purchase Contract Settlement Date in lawful money of the United States by certified or cashiers' check or wire transfer in immediately available funds payable to or upon the order of the Company. Upon receipt of notice from a Holder electing a Cash Settlement, the Agent promptly shall notify the Collateral Agent of such Holder's election. Any cash received by the Collateral Agent will be invested promptly by the Collateral Agent in Permitted Investments and paid to the Company on the Purchase Contract Settlement Date in settlement of the Purchase Contract in accordance with the terms of the Pledge Agreement. Any funds received by the Collateral Agent in respect of the investment earnings from the investment in such Permitted Investments, will be distributed to the Agent when received for payment to the Holder. (ii) A Holder of Income PRIDES who does not make an effective Cash Settlement or an Early Settlement under Section 5.9 hereof shall be deemed to have elected to pay for the shares of Common Stock to be issued under the related Purchase Contract from the proceeds of the related Preferred Securities underlying its Income PRIDES, which will be applied automatically by the Collateral Agent to pay the Purchase Price for the Purchase Contract to the Company on the Purchase Contract Settlement Date as provided in subparagraph (a)(i); and (iii) A Holder of Growth PRIDES shall pay for the shares of Common Stock to be issued under the Purchase Contract from the Proceeds of the related Pledged Treasury Securities held by the Collateral Agent, which will be applied automatically by the 44 52 Collateral Agent to pay the Purchase Price for the Purchase Contract to the Company on the Purchase Contract Settlement Date without receiving any instruction from the Holder. Upon the maturity of the Pledged Treasury Notes held by the Collateral Agent on the day immediately prior to the Purchase Contract Settlement Date, the principal amount of the Treasury Securities received by the Collateral Agent will be invested promptly in Permitted Investments. In the event the sum of the proceeds from the related Pledged Treasury Securities and the investment earnings earned from such investments is in excess of the aggregate Purchase Price of the Purchase Contracts being settled thereby, the Collateral Agent will distribute such excess to the Agent for the benefit of the Holder of the related Growth PRIDES when received. Any distribution to Holders of excess funds and interest described in subparagraph (i), (ii) or (iii) above, shall be payable at the office of the Agent in The City of New York maintained for that purpose or, at the option of the Holder, by check mailed to the address of the Person entitled thereto at such address as it appears on the Register. (b) The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificate therefor to the Holder unless it shall have received payment in full of the Purchase Price for the shares of Common Stock to be purchased thereunder in the manner herein set forth. (c) Upon Cash Settlement of any Purchase Contract, (i) the Collateral Agent will in accordance with the terms of the Pledge Agreement cause the Pledged Preferred Securities underlying the relevant Security to be released from the Pledge by the Collateral Agent free and clear of any security interest of the Company and transferred to the Agent for delivery to the Holder thereof or its designee as soon as practicable and (ii) subject to the receipt thereof from the Collateral Agent, the Agent shall, by book-entry transfer, or other appropriate procedures, in accordance with instructions provided by the Holder thereof, transfer the Pledged Preferred Security or the Pledged Treasury Securities (or, if no such instructions are given to the Agent by the Holder, the 45 53 Agent shall hold the Pledged Preferred Security or the Pledged Treasury Securities, and any distributions thereon, in the name of the Agent or its nominee in trust for the benefit of such Holder). Section 5.5. Issuance of Shares of Common Stock. Unless a Termination Event shall have occurred on or prior to the Purchase Contract Settlement Date, on the Purchase Contract Settlement Date, upon its receipt of payment in full of the Purchase Price for the shares of Common Stock purchased by the Holders pursuant to the foregoing provisions of this Article, and in payment of Deferred Contract Adjustment Payments, if any, owed by the Company to the Holders and subject to Section 5.6(b), the Company shall issue and deposit with the Agent, for the benefit of the Holders of the Outstanding Securities, one or more certificates representing the new shares of Common Stock registered in the name of the Agent (or its nominee) as custodian for the Holders (such certificates for shares of Common Stock, together with any dividends or distributions with respect thereto, being hereinafter referred to as the "Purchase Contract Settlement Fund") to which the Holders are entitled hereunder. Subject to the foregoing, upon surrender of a Certificate to the Agent on or after the Purchase Contract Settlement Date, together with settlement instructions thereon duly completed and executed, the Holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Common Stock which such Holder is entitled to receive pursuant to the provisions of this Article Five (after taking into account all Securities then held by such Holder) together with cash in lieu of fractional shares as provided in Section 5.10 and any dividends or distributions with respect to such shares constituting part of the Purchase Contract Settlement Fund, but without any interest thereon, and the Certificate so surrendered shall forthwith be cancelled. Such shares shall be registered in the name of the Holder or the Holder's designee as specified in the settlement instructions provided by the Holder to the Agent. If any shares of Common Stock issued in respect of a Purchase Contract and in payment of any Deferred Contract Adjustment Payments are to be registered to a Person other than the Person in whose name the Certificate evidencing such Purchase Contract is registered, no such registration shall be made unless the Person re- 46 54 questing such registration has paid any transfer and other taxes required by reason of such registration in a name other than that of the registered Holder of the Certificate evidencing such Purchase Contract or has established to the satisfaction of the Company that such tax either has been paid or is not payable. Section 5.6. Adjustment of Settlement Rate. (a) Adjustments for Dividends, Distributions, Stock Splits, Etc. (1) In case the Company shall pay or make a dividend or other distribution on any class of Common Stock of the Company in Common Stock, the Settlement Rate in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by dividing such Settlement Rate 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 increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (1), 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. (2) In case the Company shall issue rights, options or warrants to all holders of its Common Stock (not being available on an equivalent basis to Holders of the Securities upon settlement of the Purchase Contracts underlying such Securities) entitling them, for a period expiring within 45 days after the record date for the determination of stockholders entitled to receive such rights, options or warrants, to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price per share of the Common Stock on the date fixed for the determination of stockholders entitled 47 55 to receive such rights, options or warrants (other than pursuant to a dividend reinvestment plan), the Settlement Rate in effect at the opening of business on the day following the date fixed for such determination shall be increased by dividing such Settlement Rate 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 plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such Current Market Price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (2), 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 shall not issue any such rights, options or warrants in respect of shares of Common Stock held in the treasury of the Company. (3) In case outstanding shares of Common Stock shall be subdivided or split into a greater number of shares of Common Stock, the Settlement Rate in effect at the opening of business on the day following the day upon which such subdivision or split becomes effective shall be proportionately increased, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Settlement Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision, split or combination becomes effective. (4) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to 48 56 in paragraph (2) of this Section, any dividend or distribution paid exclusively in cash and any dividend or distribution referred to in paragraph (1) of this Section), the Settlement Rate shall be adjusted so that the same shall equal the rate determined by dividing the Settlement Rate in effect immediately prior to the close of business on the date fixed for the determination of stockholders entitled to receive such distribution by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock on the date fixed for such determination less the then fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution filed with the Agent) of the portion of the assets or evidences of indebtedness so distributed applicable to one share of Common Stock and the denominator shall all be such Current Market Price per share of the Common Stock, such adjustment to become effective immediately prior to the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such distribution. In any case in which this paragraph (4) is applicable, paragraph (2) of this Section shall not be applicable. (5) In case the Company shall, (I) by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed in a Reorganization Event to which Section 5.6(b) applies or as part of a distribution referred to in paragraph (4) of this Section) in an aggregate amount that, combined together with (II) 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 (5) or paragraph (6) of this Section has been made and (III) 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 or exchange 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 the distribution described in clause (I) above and in respect of which no adjustment pursuant to this paragraph (5) or paragraph (6) of this Section has been made, exceeds 15% of the product of the Current Market Price per share of the 49 57 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 Settlement Rate shall be increased so that the same shall equal the rate determined by dividing the Settlement Rate in effect immediately prior to 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 combined amount distributed or payable in the transactions described in clauses (I), (II) and (III) above 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. (6) In case (I) 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 (based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of Purchased Shares) of an aggregate consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that combined together with (II) 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 or exchange offer, of consideration payable in respect of any other tender or exchange offer, by the Company or any subsidiary of the Company for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender or exchange offer and in respect of which no adjustment pursuant to paragraph (5) of this Section or this paragraph (6) has been made and (III) the aggregate amount of any distributions to all holders of the Company's Common Stock made exclusively in cash within the 12 months preceding the expiration of such tender or exchange offer and in respect of which no adjustment 50 58 pursuant to paragraph (5) of this Section or this paragraph (6) has been made, exceeds 15% 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 or exchange 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 prior to the opening of business on the day after the date of the Expiration Time, the Settlement Rate shall be adjusted so that the same shall equal the rate determined by dividing the Settlement Rate immediately prior to the 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 (I) the Current Market Price per share of the Common Stock on the date of the Expiration Time and (II) 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 transactions described in clauses (I), (II) and (III) above (assuming in the case of clause (I) the acceptance, up to any maximum specified in the terms of the tender or exchange 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"). (7) The reclassification of Common Stock into securities including securities other than Common Stock (other than any reclassification upon a Reorganization Event to which Section 5.6(b) applies) shall be deemed to involve (a) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be "the date fixed for the determination of stockholders entitled to receive such distribution" and the "date fixed for such determination" within the meaning of paragraph (4) of this Section), and (b) a subdivision, split or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior 51 59 to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day upon which such subdivision or split becomes effective" or "the day upon which such combination becomes effective", as the case may be, and "the day upon which such subdivision, split or combination becomes effective" within the meaning of paragraph (3) of this Section). (8) The "Current Market Price" per share of Common Stock on any day means the average of the daily Closing Prices for the 5 consecutive Trading Days selected by the Company commencing not more than 20 Trading Days before, and ending not later than, the earlier of the day in question and the day before the "ex date" with respect to the issuance or distribution requiring such computation. For purposes of this paragraph, the term "ex date", when used with respect to any issuance or distribution, shall mean the first date on which the Common Stock trades regular way on such exchange or in such market without the right to receive such issuance or distribution. (9) All adjustments to the Settlement Rate shall be calculated to the nearest 1/10,000th of a share of Common Stock (or if there is not a nearest 1/10,000th of a share to the next lower 1/10,000th of a share). No adjustment in the Settlement Rate shall be required unless such adjustment would require an increase or decrease of at least one percent therein; provided, however, that any adjustments which by reason of this subparagraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment. If an adjustment is made to the Settlement Rate pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.6(a), an adjustment shall also be made to the Applicable Market Value solely to determine which of clauses (a), (b) or (c) of the definition of Settlement Rate in Section 5.1 will apply on the Purchase Contract Settlement Date. Such adjustment shall be made by multiplying the Applicable Market Value by a fraction of which the numerator shall be the Settlement Rate immediately after such adjustment pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.6(a) and the denominator shall be the Settlement Rate immediately before such adjustment. 52 60 (10) The Company may make such increases in the Settlement Rate, in addition to those required by this Section, as it considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes or for any other reasons. (b) Adjustment for Consolidation, Merger or Other Reorganization Event. In the event of (i) any consolidation or merger of the Company, with or into another Person (other than a merger or consolidation in which the Company is the continuing corporation and in which the Common Stock outstanding immediately prior to the merger or consolidation is not exchanged for cash, securities or other property of the Company or another corporation), (ii) any sale, transfer, lease or conveyance to another Person of the property of the Company as an entirety or substantially as an entirety, (iii) any statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition) or (iv) any liquidation, dissolution or winding up of the Company other than as a result of or after the occurrence of a Termination Event (any such event, a "Reorganization Event"), the Settlement Rate will be adjusted to provide that each Holder of Securities will receive on the Purchase Contract Settlement Date with respect to each Purchase Contract forming a part thereof, the kind and amount of securities, cash and other property receivable upon such Reorganization Event by a Holder of the number of shares of Common Stock issuable on account of each Purchase Contract if the Purchase Contract Settlement Date had occurred immediately prior to such Reorganization Event, assuming such Holder of Common Stock is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be ("Constituent Person"), or an Affiliate of a constituent Person, and failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such Reorganization Event (provided that if the kind or amount of securities, cash and other property receivable upon such Reorganization Event is not the same for each share of Common Stock held immediately prior to such Reorganization Event by other than a constituent Person or an Affiliate thereof and in 53 61 respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purpose of this Section the kind and amount of securities, cash and other property receivable upon such Reorganization Event by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). In the event of such a Reorganization Event, the Person formed by such consolidation, merger or exchange or the Person which acquires the assets of the Company or, in the event of a liquidation or dissolution of the Company, the Company or a liquidating trust created in connection therewith, shall execute and deliver to the Agent an agreement supplemental hereto providing that the Holders of each Outstanding Security shall have the rights provided by this Section 5.6. Such supplemental agreement shall provide for adjustments which, for events subsequent to the effective date of such supplemental agreement, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section. The above provisions of this Section shall similarly apply to successive Reorganization Events. Section 5.7. Notice of Adjustments and Certain Other Events. (a) Whenever the Settlement Rate is adjusted as herein provided, the Company shall: (i) forthwith compute the adjusted Settlement Rate in accordance with Section 5.6 and prepare and transmit to the Agent an Officers' Certificate setting forth the Settlement Rate, the method of calculation thereof in reasonable detail, and the facts requiring such adjustment and upon which such adjustment is based; and (ii) within 10 Business Days following the occurrence of an event that permits or requires an adjustment to the Settlement Rate pursuant to Section 5.6 (or if the Company is not aware of such occurrence, as soon as practicable after becoming so aware), provide a written notice to the Holders of the Securities of the occurrence of such event and a statement in reasonable detail setting forth the method by which the adjustment to the Settlement 54 62 Rate was determined and setting forth the adjusted Settlement Rate. (b) The 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 Settlement Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed in making the same. The Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at the time be issued or delivered with respect to any Purchase Contract; and the Agent makes no representation with respect thereto. The Agent shall not be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock pursuant to a Purchase Contract or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Section 5.8. Termination Event; Notice. The Purchase Contracts and the obligations and rights of the Company and the Holders thereunder, including, without limitation, the rights of the Holders to receive and the obligation of the Company to pay any Contract Adjustment Payments, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Agent or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall have occurred. Upon and after the occurrence of a Termination Event, the Securities shall thereafter represent the right to receive the Preferred Securities forming a part of such Securities in the case of Income PRIDES, or Treasury Securities in the case of Growth PRIDES, in accordance with the provisions of Section 4.2 and the Pledge Agreement, as applicable. Upon the occurrence of a Termination Event, the Company shall promptly but in no event later than two Business Days thereafter give written notice to the Agent, the Collateral Agent and to the Holders, at their addresses as they appear in the Register. Section 5.9. Early Settlement. 55 63 (a) Subject to and upon compliance with the provisions of this Section 5.9, at the option of the Holder thereof, Purchase Contracts underlying Securities, having an aggregate Stated Amount equal to $1,000 or an integral multiple thereof, may be settled early ("Early Settlement") as provided herein. In order to exercise the right to effect Early Settlement with respect to any Purchase Contracts, the Holder of the Certificate evidencing such Purchase Contracts shall deliver such Certificate to the Agent at the Corporate Trust Office duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early on the reverse thereof duly completed and accompanied by payment in the form of a certified or cashier's check payable to the order of the Company in an amount (the "Early Settlement Amount") equal to (i) the product of (A) the Stated Amount times (B) the number of Purchase Contracts with respect to which the Holder has elected to effect Early Settlement plus (ii) if such delivery is made with respect to any Purchase Contracts during the period from the close of business on any Record Date next preceding any Payment Date to the opening of business on such Payment Date, an amount equal to the sum of (x) the Contract Adjustment Payments payable on such Payment Date with respect to such Purchase Contracts plus (y) in the case of Income PRIDES Certificate, the distributions on the related Preferred Securities payable on such Payment Date. Except as provided in the immediately preceding sentence and subject to the second to last paragraph of Section 5.2, no payment or adjustment shall be made upon Early Settlement of any Purchase Contract on account of any Contract Adjustment Payments accrued on such Purchase Contract or on account of any dividends on the Common Stock issued upon such Early Settlement. If the foregoing requirements are first satisfied with respect to Purchase Contracts underlying any Securities at or prior to 5:00 p.m., New York City time, on a Business Day, such day shall be the "Early Settlement Date" with respect to such Securities and if such requirements are first satisfied after 5:00 p.m., New York City time, on a Business Day or on a day that is not a Business Day, the "Early Settlement Date" with respect to such Securities shall be the next succeeding Business Day. (b) Upon Early Settlement of Purchase Contracts by a Holder of the related Securities, the Company shall issue, and the Holder shall be entitled to receive, a 56 64 number of new shares of Common Stock on account of each Purchase Contract as to which Early Settlement is effected equal to the Early Settlement Rate; provided, however, that upon the Early Settlement of the Purchase Contracts, the Holder of such related Securities will forfeit the right to receive any Deferred Contract Adjustment Payments. The Early Settlement Rate shall initially be equal to and shall be adjusted in the same manner and at the same time as the Settlement Rate is adjusted. As promptly as practicable after Early Settlement of Purchase Contracts in accordance with the provisions of this Section 5.9, the Company shall issue and shall deliver to the Agent at the Corporate Trust Office a certificate or certificates for the full number of shares of Common Stock issuable upon such Early Settlement together with payment in lieu of any fraction of a share, as provided in Section 5.10. (c) The Company shall cause the shares of Common Stock issuable upon Early Settlement of Purchase Contracts, and the related Preferred Securities, in the case of Income PRIDES, or the related Treasury Securities, in the case of Growth PRIDES, deliverable, to be issued and delivered, in the case of such shares of Common Stock, and released from the Pledge by the Collateral Agent and transferred, in the case of such Preferred Securities or Treasury Securities, to the Agent, for delivery to the Holder thereof or its designee, no later than the third Business Day after the applicable Early Settlement Date. (d) Upon Early Settlement of any Purchase Contracts, and subject to receipt of shares of Common Stock from the Company and Preferred Securities or Treasury Securities, as the case may be, from the Collateral Agent, as applicable, the Agent shall, in accordance with the instructions provided by the Holder thereof on the applicable form of Election to Settle Early on the reverse of the Certificate evidencing the related Securities, (i) transfer to the Holder the Preferred Securities or Treasury Securities, as the case may be, forming a part of such Securities, and (ii) deliver to the Holder a certificate or certificates for the full number of shares of Common Stock issuable upon such Early Settlement together with payment in lieu of any fraction of a share, as provided in Section 5.10. 57 65 (e) In the event that Early Settlement is effected with respect to Purchase Contracts underlying less than all the Securities evidenced by a Certificate, upon such Early Settlement the Company shall execute and the Agent shall authenticate, countersign and deliver to the Holder thereof, at the expense of the Company, a Certificate evidencing the Securities as to which Early Settlement was not effected. (f) Holders may settle Securities early only in integral multiples of 20 Income PRIDES or one GROWTH PRIDES. Section 5.10. No Fractional Shares. No fractional shares or scrip representing fractional shares of Common Stock shall be issued or delivered upon settlement on the Purchase Contract Settlement Date or upon Early Settlement of any Purchase Contracts or with respect to the payment of Deferred Contract Adjustment Payments, if any, on the Purchase Contract Settlement Date. If Certificates evidencing more than one Purchase Contract shall be surrendered for settlement at one time by the same Holder, the number of full shares of Common Stock which shall be delivered upon settlement shall be computed on the basis of the aggregate number of Purchase Contracts evidenced by the Certificates so surrendered. Instead of any fractional share of Common Stock which would otherwise be deliverable upon settlement of any Purchase Contracts on the Purchase Contract Settlement Date or upon Early Settlement or with respect to the payment of any Deferred Contract Adjustment Payments, the Company, through the Agent, shall make a cash payment in respect of such fractional interest in an amount equal to the value of such fractional shares times the Applicable Market Value. The Company shall provide the Agent from time to time with sufficient funds to permit the Agent to make all cash payments required by this Section 5.10 in a timely manner. 58 66 Section 5.11. Charges and Taxes. The Company will pay all stock transfer and similar taxes attributable to the initial issuance and delivery of the shares of Common Stock pursuant to the Purchase Contracts and in payment of any Deferred Contract Adjustment Payments; provided, however, that the Company shall not be required to pay any such tax or taxes which may be payable in respect of any exchange of or substitution for a Certificate evidencing a Purchase Contract or any issuance of a share of Common Stock in a name other than that of the registered Holder of a Certificate surrendered in respect of the Purchase Contracts evidenced thereby, other than in the name of the Agent, as custodian for such Holder, and the Company shall not be required to issue or deliver such share certificates or Certificates unless or until the Person or Persons requesting the transfer or issuance 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. ARTICLE VI Remedies Section 6.1. Unconditional Right of Holders to Receive Contract Adjustment Payments and to Purchase Common Stock. The Holder of any Income PRIDES or Growth PRIDES shall have the right, which is absolute and unconditional (subject to the right of the Company to defer payment thereof pursuant to Section 5.3 and subject to the forfeiture of any Deferred Contract Adjustment Payments upon Early Settlement pursuant to Section 5.9(b) or upon the occurrence of a Termination Event), to receive payment of each installment of the Contract Adjustment Payments with respect to the Purchase Contract constituting a part of such Security on the respective Payment Date for such Security and to purchase Common Stock pursuant to such Purchase Contract and, in each such case, to institute suit for the enforcement of any such payment and right to purchase Common Stock, and such rights shall not be impaired without the consent of such Holder. 59 67 Section 6.2. Restoration of Rights and Remedies. If any Holder has instituted any proceeding to enforce any right or remedy under this Agreement and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to such Holder, then and in every such case, subject to any determination in such proceeding, the Company and such Holder shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of such Holder shall continue as though no such proceeding had been instituted. Section 6.3. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates in the last paragraph of Section 3.10, no right or remedy herein conferred upon or reserved to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. Section 6.4. Delay or Omission Not Waiver. No delay or omission of any Holder to exercise any right or remedy upon a default shall impair any such right or remedy or constitute a waiver of any such right. Every right and remedy given by this Article or by law to the Holders may be exercised from time to time, and as often as may be deemed expedient, by such Holders. Section 6.5. Undertaking for Costs. All parties to this Agreement agree, and each Holder of Income PRIDES or Growth PRIDES, by its acceptance of such Income PRIDES or Growth PRIDES shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Agent for any action taken, suffered or omitted by it as 60 68 Agent, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Agent, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of distributions on any Preferred Securities or Contract Adjustment Payments on any Purchase Contract on or after the respective Payment Date therefor in respect of any Security held by such Holder, or for enforcement of the right to purchase shares of Common Stock under the Purchase Contracts constituting part of any Security held by such Holder. Section 6.6. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Agreement; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Agent or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE VII The Agent Section 7.1. Certain Duties and Responsibilities. (a)(1) The Agent undertakes to perform, with respect to the Securities, such duties and only such duties as are specifically set forth in this Agree- 61 69 ment and the Pledge Agreement, and no implied covenants or obligations shall be read into this Agreement against the Agent; and (2) in the absence of bad faith or negligence on its part, the Agent may, with respect to the Securities, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Agent and conforming to the requirements of this Agreement, but in the case of any certificates or opinions which by any provision hereof are specifically required to be furnished to the Agent, the Agent shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Agreement. (b) No provision of this Agreement shall be construed to relieve the Agent from liability for its own negligent action, its own negligent failure to act, or its own wilful misconduct, except that (1) this Subsection shall not be construed to limit the effect of Subsection (a) of this Section; (2) the Agent shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Agent was negligent in ascertaining the pertinent facts; and (3) no provision of this Agreement shall require the Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if adequate indemnity is not provided to it. (c) Whether or not therein expressly so provided, every provision of this Agreement relating to the conduct or affecting the liability of or affording protection to the Agent shall be subject to the provisions of this Section. (d) The Agent is authorized to execute and deliver the Pledge Agreement in its capacity as Agent. 62 70 Section 7.2. Notice of Default. Within 30 days after the occurrence of any default by the Company hereunder, of which a Responsible Officer of the Agent has actual knowledge, the Agent shall transmit by mail to the Company and the Holders of Securities, as their names and addresses appear in the Register, notice of such default hereunder, unless such default shall have been cured or waived. Section 7.3. Certain Rights of Agent. Subject to the provisions of Section 7.1: (a) the Agent may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; (b) any request or direction of the Company mentioned herein shall be sufficiently evidenced by an Officers' Certificate, Issuer Order or Issuer Request, and any resolution of the Board of Directors of the Company may be sufficiently evidenced by a Board Resolution; (c) whenever in the administration of this Agreement the Agent shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Agent (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers' Certificate of the Company; (d) the Agent may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; (e) the Agent shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, 63 71 debenture, note, other evidence of indebtedness or other paper or document, but the Agent, in its discretion, may make reasonable further inquiry or investigation into such facts or matters related to the execution, delivery and performance of the Purchase Contracts as it may see fit, and, if the Agent shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; and (f) the Agent may execute any of the powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys or an Affiliate and the Agent shall not be responsible for any misconduct or negligence on the part of any agent or attorney or an Affiliate appointed with due care by it hereunder.

Any Registrar or any other agent of the Company, or the Agent and its Affiliates, in their individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company, the Collateral Agent or any other Person with the same rights it would have if it were not Registrar or such other agent, or the Agent. Section 7.6. Money Held in Custody. Money held by the Agent in custody hereunder need not be segregated from the other funds except to the extent required by law.

Section 7.9. Resignation and Removal; Appointment of Successor.

(c) The Agent may be removed at any time by Act of the Holders of a majority in number of the Outstanding Securities delivered to the Agent and the Company. (d) if at any time (1) the Agent fails to comply with Section 310(b) of the TIA, as if the Agent were an indenture trustee under an indenture qualified under the TIA, after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or (2) the Agent shall cease to be eligible under Section 7.8 and shall fail to resign after written request therefor by the Company or by any such Holder, or 66 74 (3) the Agent shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Agent or of its property shall be appointed or any public officer shall take charge or control of the Agent or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) the Company by a Board Resolution may remove the Agent, or (ii) any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Agent and the appointment of a successor Agent. (e) If the Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Agent for any cause, the Company, by a Board Resolution, shall promptly appoint a successor Agent and shall comply with the applicable requirements of Section 7.10. If no successor Agent shall have been so appointed by the Company and accepted appointment in the manner required by Section 7.10, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Agent.

The Company will give prompt written notice to the Agent of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby designates as the place of payment for the Securities the Corporate Trust Office and appoints the Agent at its Corporate Trust Office as paying agent in such city. Section 10.3.

No. _____ Number of Income PRIDES ___ Cusip No. ______ Form of Face of Income PRIDES Certificate _____% Income PRIDES This Income PRIDES Certificate certifies that ___________ is the registered Holder of the number of Income PRIDES set forth above. Each Income PRIDES represents (i) beneficial ownership by the Holder of one __% Trust Originated Preferred Security (the "Preferred Security") of MCN Financing III, a Delaware statutory business trust (the "Trust"), having a liquidation amount of $50, subject to the Pledge of such Preferred Security by such Holder pursuant to the Pledge Agreement, and (ii) the rights and obligations of the Holder under one Purchase Contract with MCN Corporation, a Michigan corporation, doing business as MCN Energy Group Inc. (the "Company"). All capitalized terms used herein which are defined in the Purchase Contract Agreement have the meaning set forth therein. A-1 87 Pursuant to the Pledge Agreement, the Preferred Securities constituting part of each Income PRIDES evidenced hereby have been pledged to the Collateral Agent, for the benefit of the Company, to secure the obligations of the Holder under the Purchase Contract comprising a portion of such Income PRIDES. The Pledge Agreement provides that all payments of the Stated Amount of, or cash distributions on, any Pledged Preferred Securities (as defined in the Pledge Agreement) constituting part of the Income PRIDES received by the Collateral Agent shall be paid by the Collateral Agent by wire transfer in same day funds (i) in the case of (A) cash distributions with respect to Pledged Preferred Securities and (B) any payments of the Stated Amount with respect to any Preferred Securities that have been released from the Pledge pursuant to the Pledge Agreement, to the Agent to the account designated by the Agent, no later than 2:00 p.m., New York City time, on the Business Day such payment is received by the Collateral Agent (provided that in the event such payment is received by the Collateral Agent on a day that is not a Business Day or after 12:30 p.m., New York City time, on a Business Day, then such payment shall be made no later than 10:30 a.m., New York City time, on the next succeeding Business Day) and (ii) in the case of payments of the Stated Amount of any Pledged Preferred Securities, to the Company on the relevant Payment Date (as defined herein) in accordance with the terms of the Pledge Agreement, in full satisfaction of the respective obligations of the Holders of the Income PRIDES of which such Pledged Preferred Securities are a part under the Purchase Contracts forming a part of such Income PRIDES.

MCN CORPORATION By: ---------------------------------- Name: Sebastian Coppola Title: Senior Vice President and Treasurer By: ---------------------------------- Name: Daniel L. Schiffer Title: Senior Vice President, General Counsel and Secretary Attest: - ------------------ Name: Title: HOLDER SPECIFIED ABOVE (as to obligations of such Holder under the Purchase Contracts evidenced hereby) By: THE FIRST NATIONAL BANK OF CHICAGO, not individually but solely as Attorney-in-Fact of such Holder By: ---------------------------------- Name: Title: Dated: AGENT'S CERTIFICATE OF AUTHENTICATION This is one of the Income PRIDES Certificates referred to in the within mentioned Purchase Contract Agreement. By: THE FIRST NATIONAL BANK OF CHICAGO as Agent By: ---------------------------------- Authorized Officer A-5 91 (Form of Reverse of Income PRIDES Certificate) Each Purchase Contract evidenced hereby is governed by a Purchase Contract Agreement, dated as of March __, 1997 (as supplemented from time to time, the "Purchase Contract Agreement"), between the Company and The First National Bank of Chicago, as Purchase Contract Agent (herein called the "Agent"), to which Purchase Contract Agreement and supplemental agreements thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Agent, the Company, and the Holders and of the terms upon which the Income PRIDES Certificates are, and are to be, executed and delivered. Each Purchase Contract evidenced hereby obligates the Holder of this Income PRIDES Certificate to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a price equal to the Stated Amount, a number of shares of Common Stock of the Company equal to the Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date, there shall have occurred a Termination Event, a Cash Settlement or an Early Settlement with respect to the Security of which such Purchase Contract is a part. The "Settlement Rate" is equal to (a) if the Applicable Market Value (as defined below) is equal to or greater than $35.38 (the "Threshold Appreciation Price"), 1.4132 shares of Common Stock per Purchase Contract, (b) if the Applicable Market Value is less than the Threshold Appreciation Price but is greater than $29, the number of shares of Common Stock per Purchase Contract equal to the Stated Amount divided by the Applicable Market Value and (c) if the Applicable Market Amount is less than or equal to $29, 1.7241 shares of Common Stock per Purchase Contract, in each case subject to adjustment as provided in the Purchase Contract Agreement. No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as provided in the Purchase Contract Agreement. The "Applicable Market Value" means the average of the Closing Prices per share of Common Stock on each of the twenty consecutive Trading Days ending on the second Trading Day immediately preceding the Purchase Contract Settlement Date. The "Closing Price" of the Common Stock on any date of determination means the closing sale price (or, if no closing price is reported, the last reported sale price) of the A-6 92 Common Stock on the New York Stock Exchange (the "NYSE") on such date or, if the Common Stock is not listed for trading on the NYSE on any such date, as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is so listed, or if the Common Stock is not so listed on a United States national or regional securities exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not so reported, the last quoted bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or, if such bid price is not available, the market value of the Common Stock on such date as determined by a nationally recognized independent investment banking firm retained for this purpose by the Company. A "Trading Day" means a day on which the Common Stock (A) is not suspended from trading on any national or regional securities exchange or association or over-the-counter market at the close of business and (B) has traded at least once on the national or regional securities exchange or association or over-the-counter market that is the primary market for the trading of the Common Stock. In accordance with the terms of the Purchase Contract Agreement, the Holder of this Income PRIDES Certificate shall pay the Purchase Price for the shares of Common Stock purchased pursuant to each Purchase Contract evidenced hereby by effecting a Cash Settlement on the Purchase Contract Settlement Date or an Early Settlement. A Holder of an Income PRIDES who fails to make an effective Cash Settlement or an Early Settlement in respect of a Purchase Contract prior to a Purchase Contract Settlement Date will be deemed to have elected to have requested the Trust to deliver to the Company a principal amount of the Junior Subordinated Debenture, underlying the Preferred Security equal to the Stated Amount of the Purchase Contract for application to the Purchase Price of the Common Stock. The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder unless it shall have received payment in full of the aggregate purchase price for the shares of Common Stock to be purchased thereunder in the manner herein set forth. Each Purchase Contract evidenced hereby and the obligations and rights of the Company and the Holder thereunder shall terminate if a Termination Event shall have occurred. A-7 93 Upon the occurrence of a Termination Event, the Company shall give written notice to the Agent and to the Holders, at their addresses as they appear in the Income PRIDES Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Pledged Preferred Security (as defined in the Pledge Agreement) forming a part of each Income PRIDES, or the Liquidation Distribution received in respect of such Pledged Preferred Security, from the Pledge. An Income PRIDES shall thereafter represent the right to receive the Preferred Security forming a part of such Income PRIDES, or the Liquidation Distribution received in respect of such Preferred Security, and any accrued Contract Adjustment Payments on the Purchase Contract forming a part of such Income PRIDES in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. Contract Adjustment Payments shall cease to accrue in respect of any period from and after the date of a Termination Event. Under the terms of the Pledge Agreement, the Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Pledged Preferred Securities. Upon receipt of notice of any meeting at which holders of Preferred Securities are entitled to vote or solicitation of consents, waivers or proxies of holders of Preferred Securities, the Agent shall, as soon as practicable thereafter, mail to the Income PRIDES holders a notice (a) containing such information as is contained in the notice or solicitation, (b) stating that each Income PRIDES holder on the record date set by the Agent therefor (which, to the extent possible, shall be the same date as the record date for determining the holders of Preferred Securities entitled to vote) shall be entitled to instruct the Agent as to the exercise of the voting rights pertaining to the Preferred Securities constituting a part of such holder's Income PRIDES and (c) stating the manner in which such instructions may be given. Upon the written request of the Income PRIDES holders on such record date, the Agent shall endeavor insofar as practicable to vote or cause to be voted, in accordance with the instructions set forth in such requests, the maximum number of Preferred Securities as to which any particular voting instructions are received. In the absence of specific instructions from the Holder of an Income PRIDES, the Agent shall abstain from voting the Preferred Security evidenced by such Income PRIDES. Upon the occurrence of a Tax Event, Investment Company Event or liquidation of the Trust, a principal amount of the A-8 94 Junior Subordinated Debentures constituting the assets of the Trust and underlying the Preferred Securities equal to the aggregate Stated Amount of the Pledged Preferred Securities shall be delivered to the Collateral Agent in exchange for Pledged Preferred Securities. Thereafter, the Junior Subordinated Debentures shall be held by the Collateral Agent to secure the obligations of each Holder of Income PRIDES to purchase shares of Common Stock under the Purchase Contracts constituting a part of such Income PRIDES. Following the liquidation of the Trust, the Holders and the Collateral Agent shall have such security interests, rights and obligations with respect to the Junior Subordinated Debentures as the Holders and the Collateral Agent had in respect of the Pledged Preferred Securities, and any reference in the Purchase Contract Agreement or Pledge Agreement to the Preferred Securities shall be deemed to be a reference to the Junior Subordinated Debentures. The Income PRIDES Certificates are issuable only in registered form and only in denominations of a single Income PRIDES and any integral multiple thereof. The transfer of any Income PRIDES Certificate will be registered and Income PRIDES Certificates may be exchanged as provided in the Purchase Contract Agreement. The Income PRIDES Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents permitted by the Purchase Contract Agreement. No service charge shall be required for any such registration of transfer or exchange, but the Company and the Agent may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. A holder who elects to substitute a Treasury Security for Preferred Securities, thereby creating Growth PRIDES, shall be responsible for any fees or expenses payable in connection therewith. Except as provided in the Purchase Contract Agreement, for so long as the Purchase Contract underlying an Income PRIDES remains in effect, such Income PRIDES shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Income PRIDES in respect of the Preferred Security and Purchase Contract constituting such Income PRIDES may be transferred and exchanged only as an Income PRIDES. The holder of an Income PRIDES may substitute for the Pledged Preferred Securities securing its obligation under the related Purchase Contract Treasury Securities in an aggregate principal amount equal to the aggregate Stated Amount of the Pledged Preferred Securities in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. From and after A-9 95 such Collateral Substitution, the Security for which such Pledged Treasury Securities secures the holder's obligation under the Purchase Contract shall be referred to as a "Growth PRIDES." A Holder may make such Collateral Substitution only in integral multiples of 20 Income PRIDES for each Growth PRIDES. Such Collateral Substitution may cause the aggregate principal amount of this Certificate to be increased or decreased; provided, however, the aggregate principal amount outstanding under this Income PRIDES Certificate shall not exceed $_____. All such adjustments to the aggregate principal amount of this Income PRIDES Certificate shall be duly recorded by placing an appropriate notation on the Schedule attached hereto. A Holder of a Growth PRIDES may recreate Income PRIDES by delivering to the Collateral Agent Preferred Securities with a Stated Amount equal to the aggregate principal amount of the Pledged Treasury Securities in exchange for the release of such Pledged Treasury Securities in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. Subject to the next succeeding paragraph, the Company shall pay, on each Payment Date, the Contract Adjustment Payments payable in respect of each Purchase Contract to the Person in whose name the Income PRIDES Certificate evidencing such Purchase Contract is registered at the close of business on the Record Date for such Payment Date. Contract Adjustment Payments will be payable at the office of the Agent in The City of New York or, at the option of the Company, by check mailed to the address of the Person entitled thereto at such address as it appears on the Income PRIDES Register. The Company shall have the right, at any time prior to the Purchase Contract Settlement Date, to defer the payment of any or all of the Contract Adjustment Payments otherwise payable on any Payment Date, but only if the Company shall give the Holders and the Agent written notice of its election to defer such payment (specifying the amount to be deferred) as provided in the Purchase Contract Agreement. Any Contract Adjustment Payments so deferred shall bear additional Contract Adjustment Payments thereon at the rate of 8% per annum (computed on the basis of a 360 day year of twelve 30 day months), compounding on each succeeding Payment Date, until paid in full (such deferred installments of Contract Adjustment Payments together with the additional Contract Adjustment Payments accrued thereon, are referred to herein as the A-10 96 "Deferred Contract Adjustment Payments"). Deferred Contract Adjustment Payments shall be due on the next succeeding Payment Date except to the extent that payment is deferred pursuant to the Purchase Contract Agreement. No Contract Adjustment Payments may be deferred to a date that is after the Purchase Contract Settlement Date.

Each Purchase Contract evidenced hereby obligates the Holder of this Growth PRIDES Certificate to purchase, and the Company, to sell, on May 16, 2000 (the "Purchase Contract Settlement Date"), at a price equal to $50 (the "Stated Amount"), a number of shares of Common stock, par value $.01 per share ("Common Stock"), of the Company equal to the Settlement Rate, unless on or prior to the Purchase Contract Settlement Date there shall have occurred a Termination Event or an Early Settlement with respect to the Growth PRIDES of which such Purchase Contract is a part, all as provided in the Purchase Contract Agreement and more fully described on the reverse hereof.

Schiffer Title: Senior Vice President, General Counsel and Secretary By: ---------------------------------- Name: Sebastian Coppola Title: Senior Vice President and Treasurer Attest: - ---------------------- Name: Title: HOLDER SPECIFIED ABOVE (as to obligations of such Holder under the Purchase Contracts evidenced hereby) By: THE FIRST NATIONAL BANK OF CHICAGO not individually but solely as Attorney-in-Fact of such Holder By: ---------------------------------- Name: Title: Dated: AGENT'S CERTIFICATE OF AUTHENTICATION This is one of the Growth PRIDES referred to in the within-mentioned Purchase Contract Agreement. By: THE FIRST NATIONAL BANK OF CHICAGO as Agent By: ---------------------------------- Authorized Officer B-4 108 (Form of Reverse of Growth PRIDES Certificate) Each Purchase Contract evidenced hereby is governed by a Purchase Contract Agreement, dated as of March 25, 1997 (as supplemented from time to time, the "Purchase Contract Agreement") between the Company and The First National Bank of Chicago, as Purchase Contract Agent (including its successors thereunder, herein called the "Agent"), to which the Purchase Contract Agreement and supplemental agreements thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Agent, the Company and the Holders and of the terms upon which the Growth PRIDES Certificates are, and are to be, executed and delivered. Each Purchase Contract evidenced hereby obligates the Holder of this Growth PRIDES Certificate to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a price equal to the Stated Amount, a number of shares of Common Stock of the Company equal to the Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date, there shall have occurred a Termination Event or an Early Settlement with respect to the Security of which such Purchase Contract is a part. The "Settlement Rate" is equal to (a) if the Applicable Market Value (as defined below) is equal to or greater than $35.38 (the "Threshold Appreciation Price"), 1.4132 shares of Common Stock per Purchase Contract, (b) if the Applicable Market Value is less than the Threshold Appreciation Price but is greater than $29, _____ shares of Common Stock per Purchase Contract equal to the Stated Amount divided by the Applicable Market Value and (c) if the Applicable Market Amount is less than or equal to $29, 1.7241 shares of Common Stock per Purchase Contract, in each case subject to adjustment as provided in the Purchase Contract Agreement. No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as provided in the Purchase Contract Agreement. The "Applicable Market Value" means the average of the Closing Prices per share of Common Stock on each of the twenty consecutive Trading Days ending on the second Trading Day immediately preceding the Purchase Contract Settlement Date. The "Closing Price" of the Common Stock on any date of determination means the closing sale price (or, if no closing price is reported, the last reported sale price) of the Common Stock on the New York Stock Exchange (the "NYSE") on such date or, if the Common Stock is not listed for trading on the NYSE on any such date, as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is so B-5 109 listed, or if the Common Stock is not so listed on a United States national or regional securities exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not so reported, the last quoted bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or, if such bid price is not available, the market value of the Common Stock on such date as determined by a nationally recognized independent investment banking firm retained for this purpose by the Company. A "Trading Day" means a day on which the Common Stock (A) is not suspended from trading on any national or regional securities exchange or association or over-the-counter market at the close of business and (B) has traded at least once on the national or regional securities exchange or association or over-the-counter market that is the primary market for the trading of the Common Stock. In accordance with the terms of the Purchase Contract Agreement, the Holder of this Growth PRIDES Certificate shall pay the Purchase Price for the shares of Common Stock purchased pursuant to each Purchase Contract evidenced hereby by effecting either an Early Settlement of each such Purchase Contract or by applying a principal amount of the Pledged Treasury Securities underlying such Holder's Growth PRIDES equal to the Stated Amount of such Purchase Contract to the purchase of the Common Stock. The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder unless it shall have received payment in full of the aggregate purchase price for the shares of Common Stock to be purchased thereunder in the manner herein set forth. Each Purchase Contract evidenced hereby and the obligations and rights of the Company and the Holder thereunder shall terminate if a Termination Event shall have occurred. Upon the occurrence of a Termination Event, the Company shall give written notice to the Agent and to the Holders, at their addresses as they appear in the Growth PRIDES Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Pledged Treasury Securities (as defined in the Pledge Agreement) forming a part of each Growth PRIDES. A Growth PRIDES shall thereafter represent the right to receive any accrued Contract Adjustment Payments on the Purchase Contract forming a part of such Growth PRIDES in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. Contract Adjustment Payments shall cease to accrue in respect of any period from and after the date of a Termination Event. B-6 110 The Growth PRIDES Certificates are issuable only in registered form and only in denominations of a single Growth PRIDES and any integral multiple thereof. The transfer of any Growth PRIDES Certificate will be registered and Growth PRIDES Certificates may be exchanged as provided in the Purchase Contract Agreement. The Growth PRIDES Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents permitted by the Purchase Contract Agreement. No service charge shall be required for any such registration of transfer or exchange, but the Company and the Agent may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. A holder who elects to substitute Preferred Securities for a Treasury Security, thereby creating Income PRIDES, shall be responsible for any fees or expenses associated therewith. Except as provided in the Purchase Contract Agreement, for so long as the Purchase Contract underlying a Growth PRIDES remains in effect, such Growth PRIDES shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Growth PRIDES in respect of the Treasury Security and Purchase Contract constituting such Growth PRIDES may be transferred and exchanged only as a Growth PRIDES. The holder of a Growth PRIDES may substitute for the Pledged Treasury Securities securing its obligations under the related Purchase Contract Preferred Securities with an aggregate Stated Amount equal to the aggregate principal amount of the Pledged Treasury Securities in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. From and after such substitution, the Holder's Security shall be referred to as an "Income PRIDES." Such substitution may cause the aggregate principal amount of this Certificate to be increased or decreased; provided, however, the aggregate principal amount outstanding under this Growth PRIDES Certificate shall not exceed $______. All such adjustments to the aggregate principal amount of this Growth PRIDES Certificate shall be duly recorded by placing an appropriate notation on the Schedule attached hereto. A Holder of an Income PRIDES may recreate a Growth PRIDES by delivering to the Collateral Agent Treasury Securities in an aggregate principal amount equal to the aggregate Stated Amount of the Pledged Preferred Securities in exchange for the release of such Pledged Preferred Securities in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. Any such recreation of a Growth PRIDES may be effected only in multiples of 20 Income PRIDES for each Growth PRIDES. Subject to the next succeeding paragraph, the Company shall pay, on each Payment Date, the Contract Adjustment Payments payable in respect of each Purchase Contract to the Person in whose name the Growth PRIDES Certificate evidencing such Purchase B-7 111 Contract is registered at the close of business on the Record Date for such Payment Date. Contract Adjustment Payments will be payable at the office of the Agent in The City of New York or, at the option of the Company, by check mailed to the address of the Person entitled thereto at such address as it appears on the Growth PRIDES Register. The Company shall have the right, at any time prior to the Purchase Contract Settlement Date, to defer the payment of any or all of the Contract Adjustment Payments otherwise payable on any Payment Date, but only if the Company shall give the Holders and the Agent written notice of its election to defer such payment (specifying the amount to be deferred) as provided in the Purchase Contract Agreement. Any Contract Adjustment Payments so deferred shall bear additional Contract Adjustment Payments thereon at the rate of ____% per annum (computed on the basis of a 360 day year of twelve 30 day months), compounding on each succeeding Payment Date, until paid in full (such deferred installments of Contract Adjustment Payments together with the additional Contract Adjustment Payments accrued thereon, are referred to herein as the "Deferred Contract Adjustment Payments"). Deferred Contract Adjustment Payments shall be due on the next succeeding Payment Date except to the extent that payment is deferred pursuant to the Purchase Contract Agreement. No Contract Adjustment Payments may be deferred to a date that is after the Purchase Contract Settlement Date. In the event that the Company elects to defer the payment of Contract Adjustment Payments on the Purchase Contracts until the Purchase Contract Settlement Date, the Holder of this Growth PRIDES Certificate will receive on the Purchase Contract Settlement Date, in lieu of a cash payment, a number of shares of Common Stock (in addition to a number of shares of Common Stock equal to the Settlement Rate) equal to (x) the aggregate amount of Deferred Contract Adjustment Payments payable to the Holder of the Growth PRIDES Certificate of Securities divided by (y) the Applicable Market Value. No fractional shares of Common Stock will be issued with respect to the payment of Deferred Contract Adjustment Payments on the Purchase Contract Settlement Date, as provided in the Purchase Contract Agreement. In the event the Company exercises its option to defer the payment of Contract Adjustment Payments, then, until the Deferred Contract Adjustment Payments have been paid, (a) the Company shall not declare or pay dividends on, make distributions with respect to, or redeem, purchase or acquire, or make a liquidation payment with respect to, any of its capital stock (other than (i) purchase or acquisitions of shares of Common Stock in connection with the satisfaction by the Company of its obligations under any B-8 112 employee benefit plans or the satisfaction by the Company of its obligations pursuant to any contract or security outstanding on the date of such event requiring the Company to purchase shares of Common Stock, (ii) as a result of a reclassification of the Company's capital stock or the exchange or conversion of one class or series of the Company's capital stock for another class or series of the Company's capital stock or (iii) the purchase of fractional interests in shares of the Company's capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged) or make any guarantee payments with respect to the foregoing), (b) the Company shall not make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any debt securities (including guarantees) issued by the Company that rank pari passu with or junior to such Contract Adjustment Payments and (c) the Company shall not make any guarantee payments with respect to the foregoing. The Purchase Contracts and the obligations and rights of the Company and the Holders thereunder, including, without limitation, the rights of the Holders to receive and the obligation of the Company to pay any Contract Adjustment Payments or any Deferred Contract Adjustment Payments, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Agent or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall have occurred. Upon the occurrence of a Termination Event, the Company shall promptly but in no event after two business days thereafter give written notice to the Agent, the Collateral Agent and to the Holders, at their addresses as they appear in the Growth PRIDES Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Treasury Securities from the Pledge in accordance with the provisions of the Pledge Agreement. Subject to and upon compliance with the provisions of the Purchase Contract Agreement at the option of the Holder thereof, Purchase Contracts underlying Securities having an aggregate Stated Amount equal to $1,000 or an integral multiple thereof may be settled early ("Early Settlement") as provided in the Purchase Contract Agreement. In order to exercise the right to effect Early Settlement with respect to any Purchase Contracts evidenced by this Growth PRIDES Certificate, the Holder of this Growth PRIDES Certificate shall deliver this Growth PRIDES Certificate to the Agent at the Corporate Trust Office duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early set forth below duly completed and accompanied by payment in the form of a certified or cashier's check payable to the order of the Company in an amount (the "Early Settlement B-9 113 Amount") equal to (i) the product of (A) the Stated Amount times (B) the number of Purchase Contracts with respect to which the Holder has elected to effect Early Settlement, plus (ii) if such delivery is made with respect to any Purchase Contracts during the period from the close of business on any Record Date for any Payment Date to the opening of business on such Payment Date, an amount equal to the Contract Adjustment Payments payable on such Payment Date with respect to such Purchase Contracts from the period from, but not including the Early Settlement Date, to the Payment Date. Upon Early Settlement of Purchase Contracts by a Holder of the related Securities, the Pledged Treasury Securities underlying such Securities shall be released from the Pledge as provided in the Pledge Agreement and the Holder shall be entitled to receive, a number of shares of Common Stock on account of each Purchase Contract forming part of a Growth PRIDES as to which Early Settlement is effected equal to the Early Settlement Rate; provided however, that upon the Early Settlement of the Purchase Contracts, the Holder thereof will forfeit the right to receive any Deferred Contract Adjustment Payments on such Purchase Contracts. The Early Settlement Rate shall initially be equal to 28.2646 shares of Common Stock per Growth PRIDES and shall be adjusted in the same manner and at the same time as the Settlement Rate is adjusted as provided in the Purchase Contract Agreement. Upon registration of transfer of this Growth PRIDES Certificate, the transferee shall be bound (without the necessity of any other action on the part of such transferee, except as may be required by the Agent pursuant to the Purchase Contract Agreement), under the terms of the Purchase Contract Agreement and the Purchase Contracts evidenced hereby and the transferor shall be released from the obligations under the Purchase Contracts evidenced by this Growth PRIDES Certificate. The Company covenants and agrees, and the Holder, by his acceptance hereof, likewise covenants and agrees, to be bound by the provisions of this paragraph. The Holder of this Growth PRIDES Certificate, by his acceptance hereof, authorizes the Agent to enter into and perform the related Purchase Contracts forming part of the Growth PRIDES evidenced hereby on his behalf as his attorney-in-fact, expressly withholds any consent to the assumption (i.e., affirmance) of the Purchase Contracts by the Company or its trustee in the event that the Company becomes the subject of a case under the Bankruptcy Code, agrees to be bound by the terms and provisions thereof, covenants and agrees to perform his obligations under such Purchase Contracts, consents to the provisions of the Purchase Contract Agreement, authorizes the Agent to enter into and perform the Pledge Agreement on his behalf as his attorney- B-10 114 in-fact, and consents to the Pledge of the Treasury Securities underlying this Growth PRIDES Certificate pursuant to the Pledge Agreement.

Subject to certain exceptions, the provisions of the Purchase Contract Agreement may be amended with the consent of the Holders of at least 66 2/3% of the Purchase Contracts.
