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 canceled 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 Units on the date such action is taken.

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 Unit Agent, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

The form of the Agent's certificate of authentication of the Units shall be in substantially the form set forth on the form of the Unit Certificates. 3. THE UNITS. 3.1 TITLE AND TERMS; DENOMINATIONS. The aggregate number of Units evidenced by Unit Certificates authenticated, executed on behalf of the Holders and delivered hereunder is limited to [1,500,000 (SUBJECT TO INCREASE UP TO A MAXIMUM OF 225,000 TO THE EXTENT THE OVER-ALLOTMENT OPTION OF THE UNDERWRITERS UNDER THE UNDERWRITING AGREEMENT IS EXERCISED)], except for Unit Certificates authenticated, executed and delivered upon registration of transfer of, in exchange for, or in lieu of, other Unit Certificates pursuant to Section 3.4, 3.5, 3.6 or 8.5. All of the Unit Certificates authenticated, executed and delivered hereunder shall be Normal Units except for any Unit Certificates evidencing Stripped Units issued in connection with a Stripped Unit Creation pursuant to Section 3.9 and Unit Certificates authenticated, executed and delivered upon registration of transfer of, in exchange for, or in lieu of, other Unit Certificates evidencing Stripped Units pursuant to Section 3.4, 3.5, 3.6 or 8.5. Unit Certificates shall be issuable only in registered form and only in denominations of a single Unit and any integral multiple thereof. 3.2 RIGHTS AND OBLIGATIONS EVIDENCED BY THE UNIT CERTIFICATES. Each Unit Certificate shall evidence the number of Units specified therein. Prior to the purchase, if any, of shares of Common Stock under the Purchase Contracts, the Units shall not entitle the Holders to any of the rights or privileges of a holder of shares of Common Stock, including, without limitation, the right to vote or receive any dividends or other distributions 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. 3.3 EXECUTION, AUTHENTICATION, DELIVERY AND DATING. Subject to the provisions of Section 3.9 hereof, upon the execution and delivery of this Agreement, and at any time and from time to time thereafter, the Company may deliver Unit Certificates executed by the Company to the Unit Agent for authentication, execution on behalf of the Holders and delivery, together with its Issuer Order for authentication of such Unit Certificates, and the Unit Agent in accordance with such Issuer Order shall authenticate, execute on behalf of the Holders and deliver such Unit Certificates. The Unit 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 Unit Certificates may be manual or facsimile. Unit 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 -13- individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Unit Certificates or did not hold such offices at the date of such Unit Certificates. Each Unit Certificate shall be dated the date of its authentication. No Purchase Contract or Call Option underlying a Unit evidenced by a Unit Certificate shall be valid until such Unit Certificate has been executed on behalf of the Holder by the manual signature of an authorized signatory of the Unit Agent, as such Holder's attorney-in-fact. Such signature by an authorized signatory of the Unit Agent shall be conclusive evidence that the Holder of such Unit Certificate has entered into the Purchase Contracts and Call Options underlying the Units evidenced by such Unit Certificate. No Unit Certificate shall be entitled to any benefit under this Agreement or be valid or obligatory for any purpose unless there appears on such Unit Certificate a certificate of authentication substantially in the form provided for herein executed by an authorized signatory of the Unit Agent by manual signature, and such certificate upon any Unit Certificate shall be conclusive evidence, and the only evidence, that such Unit Certificate has been duly authenticated and delivered hereunder. 3.4 TEMPORARY UNIT CERTIFICATES. Pending the preparation of definitive Unit Certificates, the Company shall execute and deliver to the Unit Agent, and the Unit Agent shall authenticate, execute on behalf of the Holders, and deliver, in lieu of such definitive Unit Certificates, temporary Unit Certificates which are in substantially the form set forth in Exhibit A or Exhibit B hereto, 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 Units are listed or Depositary therefor, or as may, consistently herewith, be determined by the officers of the Company executing such Unit Certificates, as evidenced by their execution of the Unit Certificates. If temporary Unit Certificates are issued, the Company will cause definitive Unit Certificates to be prepared without unreasonable delay. After the preparation of definitive Unit Certificates, the temporary Unit Certificates shall be exchangeable for definitive Unit Certificates upon surrender of the temporary Unit Certificates at the Corporate Trust Office, at the expense of the Company and without charge to the Holder. Upon surrender for cancellation of any one or more temporary Unit Certificates, the Company shall execute and deliver to the Unit Agent, and the Unit Agent shall authenticate, execute on behalf of the Holder, and deliver in exchange therefor, one or more definitive Unit Certificates of authorized denominations and evidencing a like number of Normal Units or Stripped Units, as the case may be, as the temporary Unit Certificate or Unit Certificates so surrendered. Until so exchanged, the temporary Unit Certificates shall in all respects evidence the same benefits and the same obligations with respect to the Units evidenced thereby as definitive Unit Certificates. 3.5 REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE. The Unit Agent shall keep at the Corporate Trust Office registers (the registers maintained in such office being herein referred -14- to as the "Unit Registers") in which, subject to such reasonable regulations as it may prescribe, the Unit Agent shall provide for the registration of Unit Certificates evidencing the Normal Units and the Stripped Units and of transfers of Unit Certificates evidencing the Normal Units and the Stripped Units (the Unit Agent, in such capacity, the "Unit Registrar"). Upon surrender for registration of transfer of any Unit Certificate at the Corporate Trust Office, the Company shall execute and deliver to the Unit Agent, and the Unit 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 Unit Certificates evidencing a like number of Normal Units or Stripped Units, as the case may be. At the option of the Holder, Unit Certificates may be exchanged for other Unit Certificates evidencing a like number of Normal Units or Stripped Units, as the case may be, upon surrender of the Unit Certificates to be exchanged at the Corporate Trust Office. Whenever any Unit Certificates are so surrendered for exchange, the Company shall execute and deliver to the Unit Agent, and the Unit Agent shall authenticate, execute on behalf of the Holder, and deliver the Unit Certificates which the Holder making the exchange is entitled to receive. All Unit Certificates issued upon any registration of transfer or exchange of a Unit Certificate shall evidence the ownership of the same number of Normal Units or Stripped Units, as the case may be, and be entitled to the same benefits and subject to the same obligations, under the Principal Agreements as the Normal Units or Stripped Units, as the case may be, evidenced by the Unit Certificate surrendered upon such registration of transfer or exchange. Every Unit Certificate presented or surrendered for registration of transfer or for exchange shall (if so required by the Unit Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Unit 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 Unit Certificate, but the Company and the Unit 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 Unit Certificates (which, for these purposes, includes a Stripped Unit Creation or a transfer of Pledged Securities as contemplated by Section 5.4(a)), 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 Unit Agent, and the Unit Agent shall not be obligated to authenticate, execute on behalf of the Holder and deliver any Unit Certificate in respect of a Unit Certificate presented or surrendered for registration of transfer or for exchange on or after the Stock Purchase Date or the Termination Date. In lieu of delivery of a new Unit Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Unit Agent shall (a) if the Stock Purchase Date has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts -15- forming a part of the Units evidenced by such Unit Certificate, or (b) if a Termination Event shall have occurred on or prior to the Stock Purchase Date, transfer the liquidation or principal amount of the Pledged Securities evidenced thereby, in each case subject to the applicable conditions and in accordance with the applicable provisions of Article Five hereof. The provisions of Clauses (a), (b), (c) and (d) below shall apply only to Global Unit Certificates: (a) Each Global Unit Certificate authenticated and executed on behalf of the Holders under this Agreement shall be registered in the name of the Depositary designated for such Global Unit Certificate or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Unit Certificate shall constitute a single Unit Certificate for all purposes of this Agreement. (b) Notwithstanding any other provision in this Agreement, no Global Unit Certificate may be exchanged in whole or in part for Unit Certificates registered, and no transfer of a Global Unit Certificate in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Unit Certificate or a nominee thereof unless (i) such Depositary (x) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Unit Certificate or (y) has ceased to be a clearing agency registered under the Exchange Act or (ii) there shall have occurred and be continuing a default by the Company in respect of its obligations under one or more Principal Agreements. (c) Subject to Clause (b) above, any exchange of a Global Unit Certificate for other Unit Certificates may be made in whole or in part, and all Unit Certificates issued in exchange for a Global Unit Certificate or any portion thereof shall be registered in such names as the Depositary for such Global Unit Certificate shall direct. (d) Every Unit Certificate authenticated and delivered upon registration of transfer of, in exchange for or in lieu of a Global Unit Certificate or any portion thereof, whether pursuant to this Section, Section 3.4, 3.6 or 8.5 or otherwise, shall be authenticated, executed on behalf of the Holders and delivered in the form of, and shall be, a Global Unit Certificate, unless such Unit Certificate is registered in the name of a Person other than the Depositary for such Global Unit Certificate or a nominee thereof. 3.6 MUTILATED, DESTROYED, LOST AND STOLEN UNIT CERTIFICATES. If any mutilated Unit Certificate is surrendered to the Unit Agent, the Company shall execute and deliver to the Unit Agent, and the Unit Agent shall authenticate, execute on behalf of the Holder, and deliver in exchange therefor, a new Unit Certificate, evidencing the same number of Normal Units or Stripped Units, as the case may be, and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Unit Agent (a) evidence to their satisfaction of the destruction, loss or theft of any Unit Certificate, and (b) such security or indemnity as may be required by them to save each of them and any agent of any of them harmless, then, in the absence of notice to the Company or the Unit Agent that such Unit -16- Certificate has been acquired by a bona fide purchaser, the Company shall execute and deliver to the Unit Agent, and the Unit Agent shall authenticate, execute on behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed, lost or stolen Unit Certificate, a new Unit Certificate, evidencing the same number of Normal Units or Stripped Units, 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 Unit Agent, and the Unit Agent shall not be obligated to authenticate, execute on behalf of the Holder, and deliver to the Holder, on or after the Stock Purchase Date or the Termination Date, a Unit Certificate in respect of any mutilated, destroyed, lost or stolen Unit Certificate. In lieu of delivery of a new Unit Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Unit Agent shall (a) if the Stock Purchase Date has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Units evidenced by such Unit Certificate, or (b) if a Termination Event shall have occurred on or prior to the Stock Purchase Date, transfer the liquidation or principal amount of the Pledged Securities evidenced thereby, in each case subject to the applicable conditions and in accordance with the applicable provisions of Article Five hereof. Upon the issuance of any new Unit Certificate under this Section, the Company and the Unit 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 Unit Agent) connected therewith. Every new Unit Certificate issued pursuant to this Section in lieu of any destroyed, lost or stolen Unit Certificate shall constitute an original additional contractual obligation of the Company and of the Holder, whether or not the destroyed, lost or stolen Unit Certificate shall be at any time enforceable by anyone, and shall be entitled to all the benefits and be subject to all the obligations of the Principal Agreements equally and proportionately with any and all other Unit 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 settlement of mutilated, destroyed, lost or stolen Unit Certificates. 3.7 PERSONS DEEMED OWNERS. Prior to due presentment of a Unit Certificate for registration of transfer, the Company and the Unit Agent, and any agent of the Company or the Unit Agent, may treat the Person in whose name such Unit Certificate is registered as the owner of the Units evidenced thereby, for the purpose of receiving payments of distributions or interest on the Pledged Securities, receiving or making payments of Contract Fees and performance of the underlying Purchase Contracts and Call Options and for all other purposes whatsoever, whether or not the payment of distributions or interest on the Pledged Securities or any Contract Fee payable in respect of the Purchase Contracts constituting a part of the Units evidenced thereby shall be overdue and notwithstanding any notice to the contrary, and neither the Company -17- nor the Unit Agent, nor any agent of the Company or the Unit Agent, shall be affected by notice to the contrary. Notwithstanding the foregoing, with respect to any Global Unit Certificate, nothing herein shall prevent the Company, the Unit Agent or any agent of the Company or the Unit Agent, from giving effect to any written certification, proxy or other authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such Global Unit Certificate or impair, as between such Depositary and owners of beneficial interests in such Global Unit Certificate, the operation of customary practices governing the exercise of rights of such Depositary (or its nominee) as Holder of such Global Unit Certificate. 3.8 CANCELLATION. All Unit Certificates surrendered for delivery of shares of Common Stock on or after the Stock Purchase Date, transfer of Pledged Securities after the occurrence of a Termination Event or registration of transfer or exchange shall, if surrendered to any Person other than the Unit Agent, be delivered to the Unit Agent and, if not already canceled, shall be promptly canceled by it. The Company may at any time deliver to the Unit Agent for cancellation any Unit Certificates previously authenticated, executed and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Unit Certificates so delivered shall, upon Issuer Order, be promptly canceled by the Unit Agent. No Unit Certificates shall be authenticated, executed on behalf of the Holder and delivered upon transfer of, in exchange for or in lieu of any Unit Certificates canceled as provided in this Section, except as expressly permitted by this Agreement. All canceled Unit Certificates held by the Unit Agent shall be disposed of as directed by Issuer Order. If the Company or any Affiliate of the Company shall acquire any Unit Certificate, such acquisition shall not operate as a cancellation of such Unit Certificate unless and until such Unit Certificate is delivered to the Unit Agent canceled or for cancellation. 3.9 SUBSTITUTION OF PLEDGED SECURITIES AND CREATION OF STRIPPED UNITS; UNITS NOT OTHERWISE SEPARABLE. (a) A Holder of Normal Units may obtain the release from the Pledge of such Holder's Pledged Securities underlying such Normal Units, free and clear of the Company's and the Call Option Holder's security interests therein, and convert such Normal Units into Stripped Units (collectively, a "Stripped Unit Creation") at any time after the original issuance of such Normal Units and on or prior to the second Business Day immediately preceding the Stock Purchase Date by: (i) delivering to the Collateral Agent: (w) Treasury Securities that through their scheduled payments will generate not later than the Stock Purchase Date an amount of cash that is at least equal to the aggregate Stated Amount of such Normal Units, (x) if any Contract Fees are or will be payable by the Holders to the Company, Treasury Securities that through their scheduled payments will generate not later than each Quarterly Payment Date falling after the date on which the requirements for such Stripped Unit Creation contained in this -18- Section 3.9(a) are satisfied and on or before the Stock Purchase Date an amount of cash that is at least equal to the aggregate Contract Fees that are scheduled to be payable in respect of the Purchase Contracts underlying such Normal Units on such Quarterly Payment Date (assuming for this purpose that no Contract Fees will then have been deferred under Section 5.3); (y) if there are any deferred Contract Fees payable by such Holder to the Company on the date on which the requirements for such Stripped Unit Creation contained in this Section 3.9(a) are satisfied, an amount of cash equal to (1) the aggregate unpaid amount of such Contract Fees accrued to such date, if such date is a Quarterly Payment Date, and (2) the aggregate unpaid amount of such Contract Fees accrued to the Quarterly Payment Date immediately preceding such date plus interest thereon at a rate per annum equal to the Contract Fee Rate for the period from and including such Quarterly Payment Date to but excluding such date (calculated on the basis of a 360-day year of twelve 30-day months), if such date is not a Quarterly Payment Date; and (z) if the Call Options underlying such Normal Units remain exercisable on the date on which the requirements contained in this Section 3.9(a) for such Stripped Unit Creation are satisfied, an instrument from the Call Option Holder releasing its security interest in the Pledged Securities securing such Call Options and agreeing that such Call Options no longer underlie such Normal Units (or the Stripped Units they become); and (ii) surrendering the Unit Certificate evidencing such Normal Units, with the form of Request to Create Stripped Units thereon duly completed and executed, to the Unit Agent, whereupon the Unit Agent shall promptly request the Collateral Agent to release the Pledged Securities underlying such Normal Units; provided, however, that if Treasury Securities are the Pledged Securities underlying such Normal Units, a Stripped Unit Creation may only be effected with respect to a number of Normal Units that will result in the release from the Pledge of Treasury Securities in denominations of $1,000 or integral multiples thereof. (b) Upon receipt of the items described in clause (i) of Section 3.9(a) above and the request from the Unit Agent described in clause (ii) of Section 3.9(a) above, the Collateral Agent will, in accordance with the terms of the Pledge Agreement, release to the Unit Agent, on behalf of the Holder, from the Pledge, free and clear of the Company's and the Call Option Holders's security interests therein, the securities that theretofore had been the Pledged Securities underlying such Normal Units, and upon receipt thereof the Unit Agent shall promptly: (i) cancel the Unit Certificate for such Normal Units; (ii) transfer such released Pledged Securities to the Holder or, subject to Section 3.5, the Holder's designee; (iii) authenticate, execute on behalf of such Holder and deliver to the Holder or, subject to Section 3.5, the Holder's designee a Unit Certificate executed -19- by the Company in accordance with Section 3.3 evidencing a number of Stripped Units equal to the number of such Normal Units. Concurrently with the release of the securities that theretofore had been the Pledged Securities underlying such Normal Units as contemplated by the preceding sentence, the Treasury Securities delivered to the Collateral Agent as contemplated by clause (i) of Section 3.9(a) above shall thereupon be substituted for such securities as Pledged Securities underlying the Stripped Units created from such Normal Units. (c) Except for a Stripped Unit Creation effected in compliance with this Section 3.9, for so long as the Purchase Contract underlying a Normal Unit remains in effect such Normal Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Normal Unit in respect of the Pledged Securities, Purchase Contract and Call Option underlying such Normal Unit may be acquired, and may be transferred and exchanged, only as an integrated Normal Unit. For so long as the Purchase Contract underlying a Stripped Unit remains in effect such Stripped Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Stripped Unit in respect of the Pledged Securities and Purchase Contract underlying such Stripped Unit may be acquired, and may be transferred and exchanged, only as an integrated Stripped Unit. Other than a Unit Certificate, no Holder of a Unit, nor any transferee thereof, shall be entitled to receive a certificate evidencing the ownership of Pledged Securities or any other rights or obligations underlying such Unit for so long as the Purchase Contract underlying such Unit remains in effect. 3.10 PAYMENTS ON THE UNITS. Contract Fees (if any) payable by the Company to the Holders, and all amounts payable to Holders as required by Section 4.1 or 5.4(b), will be payable at the office of the Unit 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 address as it appears on the relevant Unit Register; provided, however, that for so long as any Units are evidenced by Global Certificates, the Unit Agent will pay each such amount payable in respect of such Units by wire transfer in same-day funds, no later than 2:00 p.m., New York City time, on the Business Day such amount is received by the Unit Agent (or, if such amount is received by the Unit Agent after 1:00 p.m., New York City time, on a Business Day or on a day that is not a Business Day, no later than 10:00 a.m., New York City time, on the next succeeding Business Day), to the Depositary, to the account or accounts designated by it for such purpose. 4. THE PLEDGED SECURITIES. 4.1 PAYMENTS ON THE PLEDGED SECURITIES. As provided by the terms of the Pledge Agreement, on each Quarterly Payment Date, subject to receipt by the Collateral Agent of the relevant payments in respect of the Pledged Securities underlying any Holder's Units, (a) the Collateral Agent (i) shall, on behalf of such Holder, pay to the Company the Contract Fees, if any, then payable by such Holder to the Company and (ii) shall, subject to Section 5.4(b), remit to the Unit Agent the amount of such payments remaining after the payment referred to in clause (i) and (b) the amount referred to in clause (a)(ii) above shall, subject to receipt thereof by the -20- Unit Agent from the Collateral Agent, be paid to the Person in whose name the Unit Certificate (or one or more Predecessor Unit Certificates) evidencing such Units is registered at the close of business on the Record Date next preceding such Quarterly Payment Date. In addition, in the event that (a) the Call Options are exercised and the Aggregate Consideration Deliverable on Exercise of the Call Options includes a cash amount in respect of deferred distributions on the QUIPS or deferred interest payments on the Junior Subordinated Debentures and (b) the Call Settlement Date is not a Quarterly Payment Date, pursuant to the Pledge Agreement the Collateral Agent shall, on behalf of the Holders of the Normal Units, pay to the Company on the Call Settlement Date an amount equal to the Contract Fees, if any, then payable by such Holders to the Company. 4.2 TRANSFER OF PLEDGED SECURITIES UPON OCCURRENCE OF TERMINATION EVENT. Upon the occurrence of a Termination Event and the transfer to the Unit Agent of the Pledged Securities underlying each Holder's Units pursuant to the terms of the Pledge Agreement, the Unit Agent shall request transfer instructions with respect to such Pledged Securities from such Holder by written request mailed to such Holder at his address as it appears in the relevant Unit Register. Thereafter, upon surrender to the Unit Agent of a Unit Certificate evidencing a Holder's Units, with transfer instructions in proper form for transfer of the underlying Pledged Securities, the Unit Agent shall transfer the Pledged Securities evidenced by such Unit Certificate to such Holder in accordance with such instructions; provided, however, that if the Pledged Securities are to be transferred to a Person other than the Person in whose name such Unit Certificate is registered, no such transfer shall be made unless the Person requesting the transfer has paid any transfer and other taxes required by reason of such transfer to a Person other than the registered Holder of such Unit Certificate or has established to the satisfaction of the Company that such tax either has been paid or is not payable. Until the foregoing conditions to transfer any of the Pledged Securities underlying any Units has been met, the Unit Agent shall hold such Pledged Securities as custodian for the Holder of such Units. If upon a Termination Event any Holder of Units would, after satisfying the foregoing conditions, otherwise be entitled to receive (or have transferred to such Holder's designee) Treasury Securities of any series having a principal amount that is not an integral multiple of $1,000, such Holder shall instead be entitled to receive (or have transferred to such Holder's designee) Treasury Securities of such series in a principal amount equal to the next lower integral multiple of $1,000 plus a portion of the net proceeds from the sale of Treasury Securities of such series contemplated by the succeeding sentence representing such Holder's interest therein. As soon as practicable after transfer to the Unit Agent of the Pledged Securities as provided in the Pledge Agreement, the Unit Agent shall, on behalf of all Holders who, by virtue of the preceding sentence, will not be entitled to a portion of the Treasury Securities of any series to which they would otherwise be entitled aggregate and sell the Treasury Securities of such series representing such portion to or through one or more U.S. government securities dealers at then prevailing prices, deduct from the proceeds of such sales all commissions and other out-of-pocket transaction costs incurred in connection with such sales and, until the net proceeds therefrom have been distributed to the Holders entitled thereto or their designees, hold such proceeds in trust for such Holders. -21- 5. THE PURCHASE CONTRACTS. 5.1 PURCHASE OF SHARES OF COMMON STOCK. Each Purchase Contract underlying a Unit shall obligate the Holder of such Unit to purchase, and the Company to sell, on the Stock Purchase Date, at a price equal to the Stated Amount, a number of shares of Common Stock equal to the Settlement Rate, unless, on or prior to the Stock Purchase Date, there shall have occurred a Termination Event. The "Settlement Rate" is equal to (a) if the Applicable Market Value (as defined below) is greater than or equal to $________ (the "Threshold Appreciation Price"), _______________ of a share of Common Stock per Purchase Contract, (b) if the Applicable Market Value is less than the Threshold Appreciation Price but is greater than the Stated Amount, a fractional share of Common Stock per Purchase Contract equal to the Stated Amount divided by the Applicable Market Value (rounded upward or downward to the nearest 1/10,000th of a share or, if there is not a nearest 1/10,000th of a share, to the next lower 1/10,000th of a share) and (c) if the Applicable Market Value is less than or equal to the Stated Amount, one share of Common Stock per Purchase Contract, in each case subject to adjustment as provided in Section 5.6. As provided in Section 5.9, 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 last Trading Day immediately preceding the Stock Purchase 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 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 a Unit Certificate evidencing Normal Units, by his acceptance thereof, irrevocably authorizes the Unit Agent to enter into and perform the underlying Purchase Contracts and Call Options on his behalf as his attorney-in-fact, agrees to be bound by the terms and provisions thereof, covenants and agrees to perform his obligations under such Purchase Contracts and Call Options, consents to the provisions of the Principal Agreements, irrevocably authorizes the Unit Agent to enter into and perform the Call Option Agreement and the Pledge Agreement on his behalf as his attorney-in-fact, and consents to and agrees to be bound by the Pledge of the Pledged Securities underlying such Normal Units pursuant to the Pledge -22- Agreement. Each Holder of a Unit Certificate evidencing Stripped Units, by his acceptance thereof, irrevocably authorizes the Unit Agent to enter into and perform the underlying Purchase Contracts on his behalf as his attorney-in-fact, 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 Principal Agreements, irrevocably authorizes the Unit Agent to perform the Pledge Agreement on his behalf as his attorney-in-fact, and consents to and agrees to be bound by the Pledge of the Pledged Securities underlying such Stripped Units pursuant to the Pledge Agreement. Each Holder of Units, by his acceptance thereof, further irrevocably covenants and agrees that, unless such Holder satisfies its obligations to the Company under the Purchase Contracts underlying such Units as provided in Section 5.4(a), then to the extent and in the manner provided in Section 5.4(b) and the Pledge Agreement, but subject to the terms thereof, payments in respect of all or a portion of the principal of or proceeds from the Pledged Securities on the Stock Purchase 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 Unit Certificate, the transferee shall be bound (without the necessity of any other action on the part of such transferee) by the terms of the Purchase Contracts and any Call Options evidenced thereby and by the Pledge Agreement and the transferor shall be released from all such obligations evidenced by the Unit Certificate so transferred. The Company covenants and agrees, and each Holder of a Unit Certificate, by his acceptance thereof, likewise covenants and agrees, to be bound by the provisions of this paragraph. 5.2 CONTRACT FEES. Subject to Section 5.3, if any Contract Fees are or will be payable by the Company to the Holders, the Company shall pay, prior to 2:00 p.m., New York City time, on each Quarterly Payment Date to and including the Stock Purchase Date, the Contract Fees payable in respect of each Purchase Contract to the Person in whose name the Unit Certificate (or one or more Predecessor Unit Certificates) evidencing such Purchase Contract is registered at the close of business on the Record Date next preceding such Quarterly Payment Date. The Company's obligations with respect to such Contract Fees [SUBORDINATION LANGUAGE FROM INDENTURE TO BE INSERTED]. Subject to Section 5.3, if any Contract Fees are or will be payable by the Holders to the Company, the Collateral Agent, on behalf of the Holders, shall pay, on each Quarterly Payment Date to and including the Stock Purchase Date, the Contract Fees payable in respect of each Purchase Contract to the Company. Such payment will be funded out of payments received by the Collateral Agent in respect of Pledged Securities. Each Unit Certificate delivered under this Agreement upon registration of transfer of, in exchange for or in lieu of any other Unit Certificate shall carry the rights to receive and obligations to pay Contract Fees accrued and unpaid, and to accrue, which were carried by the Purchase Contracts evidenced by such other Unit Certificate. -23- 5.3 DEFERRAL OF PAYMENT DATES FOR CONTRACT FEE. So long as no default in the Company's obligations under the Principal Agreements has occurred and is continuing, the Company shall have the right, at any time prior to the Stock Purchase Date, to defer the payment of any or all of the Contract Fees, if any, otherwise payable by the Company on any Quarterly Payment Date, but only if the Company shall give the Holders and the Unit Agent written notice of its election to defer such payment (specifying the amount to be deferred) at least five Business Days prior to the earlier of (a) the next succeeding Quarterly Payment Date or (b) the date the Company is required to give notice of the Record Date or Quarterly Payment Date with respect to payment of such Contract Fee to the NYSE or other applicable self-regulatory organization or to Holders, or (c) the Record Date for such Quarterly Payment Date. Any Contract Fees so deferred shall bear additional Contract Fees thereon at a rate per annum equal to the Contract Fee Rate (computed on the basis of a 360-day year of twelve 30-day months), compounding on each succeeding Quarterly Payment Date, until paid in full. Deferred Contract Fees (and additional Contract Fees accrued thereon) shall be due on the next succeeding Quarterly Payment Date except to the extent that payment is deferred pursuant to this Section. No Contract Fees may be deferred to a date that is after the Stock Purchase Date. In the event the Company exercises its option to defer the payment of Contract Fees (if any) payable by it, then, until all deferred Contract Fees (including additional Contract Fees accrued thereon) have been paid in full, the Company shall not (a) declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company's capital stock, (b) make any payment of principal, interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company that rank part passu with or junior in right of payment to the Contract Fees or (c) make any guarantee payments with respect to any guarantee by the Company of any securities of any subsidiary of the Company if such guarantee ranks pari passu or junior in right of payment to the Contract Fees (other than, in the case of clauses (a), (b) and (c), (i) dividends or distributions in shares of, or options, warrants or rights to subscribe for or purchase shares of, common stock of the Company, (ii) any declaration of a dividend in connection with the implementation of a stockholder's rights plan, or the issuance of stock under any such plan in the future, or the redemption or repurchase of any such rights pursuant thereto, (iii) payments under the Company's guarantee of the QUIPS, (iv) as a result of a reclassification of the Company's capital stock solely into shares of one or more classes or series 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, (v) 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 securities being converted or exchanged and (vi) purchases of common stock in connection with the satisfaction by the Company of its obligations under any of the Company's benefit plans for its and its subsidiaries' directors, officers or employees or any of the company's dividend reinvestment plans). If any Contract Fees are payable by a Holder to the Company and payments made in respect of Pledged Securities underlying such Holder's Units are insufficient to cover such Holder's obligation to pay such Contract Fees, such obligation shall be deferred until the earlier of the date sufficient cash is available and the Stock Purchase Date. Any such Contract Fees so deferred shall bear additional Contract Fees thereon at a rate per annum equal to the Contract Fee -24- Rate (computed on the basis of a 360-day year of twelve 30-day months), compounding on each succeeding Quarterly Payment Date, until paid in full. 5.4 PAYMENT OF PURCHASE PRICE. (a) A Holder of Units shall, by no later than 10:00 a.m., New York City time, on the Stock Purchase Date, deliver to the Unit Agent payment of the purchase price for the shares of Common Stock to be purchased pursuant to the Purchase Contracts underlying such Units, which payment shall be made in lawful money of the United States by certified or cashier's check payable to the order of the Company in immediately available funds in an amount equal to the aggregate Stated Amount of such Holder's Units, plus, if there are unpaid Contract Fees accrued and payable by such Holder to the Company on the Stock Purchase Date and the cash received by the Collateral Agent on such date in respect of the Pledged Securities underlying such Units is less than the amount of such unpaid Contract Fees, an amount sufficient to cover such shortfall. By 11:00 a.m., New York City time, on the Stock Purchase Date, the Unit Agent shall (i) transfer to the Company all of the payments the Company shall have received as contemplated by the preceding sentence, (ii) notify the Collateral Agent and the Company as to the number of Normal Units and the number of Stripped Units, respectively, with respect to which payment has been received as aforesaid (such Units being collectively referred to as "Paid Units") and the number of Normal Units and the number of Stripped Units, respectively, with respect to which payment has not been received as aforesaid (such Units being collectively referred to as "Unpaid Units"), and (iii) request the Collateral Agent to release the Pledged Securities underlying the Paid Units (or, in the case of Treasury Securities, the cash payments received thereon) from the Pledge to the Unit Agent (for delivery to the Holders of such Units entitled thereto), free and clear of the Company's security interest therein. By 1:00 p.m., New York City time, on the Stock Purchase Date, the Collateral Agent shall, as provided by the terms of the Pledge Agreement, comply with the request referred to in clause (iii) of the preceding sentence (subject to the Company's right to prevent the Collateral Agent from doing so to the extent the aggregate amount the Company has received as contemplated by clause (i) of the preceding sentence is less than the aggregate amount payable with respect to the Units referred to in such request). The Unit Agent shall thereupon, subject to its receipt from the Collateral Agent of the Pledged Securities (or cash) referred to in such request and subject to Section 3.5, transfer such released Pledged Securities (or cash) to the respective Holders entitled thereto in accordance with the settlement instructions specified in the form of Settlement Instructions appearing on the Unit Certificates evidencing the Paid Units; provided, however, that if any such Unit Certificate is not surrendered to the Unit Agent with the form of Settlement Instructions thereon duly completed and executed, the Unit Agent shall hold such Pledged Securities (or cash), and any distributions or interest received on such Pledged Securities, as custodian for the Holder entitled thereto, to be delivered to such Holder (without any interest thereon and subject to Section 3.5) upon surrender of such Unit Certificate to the Unit Agent (with the form of Settlement Instructions thereon duly completed and executed). -25- (b) With respect to each Holder's Unpaid Units, pursuant to the terms of the Pledge Agreement, (i) (x) if QUIPS underlie such Unpaid Units, the Collateral Agent, on behalf of such Holder, shall exercise such Holder's right under the Declaration to require the Trust to distribute Junior Subordinated Debentures having an aggregate principal amount equal to the aggregate liquidation amount of such QUIPS, in exchange for such QUIPS, and, upon receiving such Junior Subordinated Debentures, shall thereupon, as Put Agent, exercise the Junior Subordinated Debenture Put Option with respect thereto and (y) if Junior Subordinated Debentures underlie such Unpaid Units, the Collateral Agent, on behalf of such Holder, shall, as Put Agent, exercise the Junior Subordinated Debenture Put Option with respect thereto; (ii) the Collateral Agent shall deliver to the Company, out of the proceeds from the exercise of such Junior Subordinated Debenture Put Option or, if Treasury Securities underlie such Unpaid Units, the proceeds from the payment of such Treasury Securities at maturity, an amount equal to the aggregate Stated Amount of such Unpaid Units plus the Unpaid Contract Fees, if any, payable by such Holder to the Company in respect of such Unpaid Units to satisfy in full such Holder's obligations under such Unpaid Units; and (iii) the Collateral Agent shall remit to the Unit Agent, on behalf of such Holder, the remainder of the proceeds, if any, from the Pledged Securities underlying such Unpaid Units for distribution to such Holder. The amount referred to in clause (iii) above shall, subject to receipt thereof by the Unit Agent from the Collateral Agent, be paid to the Person in whose name the Unit Certificate (or one or more Predecessor Unit Certificates) evidencing such Unpaid Units is registered at the close of Business on the Record Date next preceding the Stock Purchase Date. (c) Each Holder will be entitled to apply any unpaid amounts owing by the Company to such Holder as a set-off to reduce, dollar-for-dollar, any amounts then owing by such Holder to the Company in respect of such Holder's Units, and such set-off amounts will be treated for all purposes as having been paid in full by such Holder as required hereby. (d) 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 of the related Unit unless the Company 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 (either directly or by operation of set-off as contemplated by the preceding sentence). 5.5 ISSUANCE OF SHARES OF COMMON STOCK. On the Stock Purchase Date, upon receipt by the Company of payment in full of the aggregate purchase price for the shares of Common Stock purchased by the Holders pursuant to the foregoing provisions of this Article, and subject to -26- Section 5.6(b), the Company shall deposit with the Unit Agent, for the benefit of the Holders of the Units, one or more certificates representing the shares of Common Stock registered in the name of the Unit 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 Unit Certificate to the Unit Agent on or after the Stock Purchase Date, with the form of Settlement Instructions thereon duly completed and executed, the Holder of such Unit 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 Units then held by such Holder) together with cash in lieu of fractional shares as provided in Section 5.9 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 Unit 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 form of Settlement Instructions appearing on the surrendered Unit Certificate. If any shares of Common Stock issued in respect of a Purchase Contract are to be registered to a Person other than the Person in whose name the Unit Certificate evidencing such Purchase Contract is registered, no such registration shall be made unless the Person requesting 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 Unit 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. 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. -27- (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 Units upon settlement of the Purchase Contracts underlying such Units) 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 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 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 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 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 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 -28- 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 Unit 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, 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 (I) 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 (II) 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), as of the expiration of such tender or exchange offer, 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 expiring 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, exceeds 12.5% of the product of the Current Market Price per share of the Common Stock on the date for the determination of holders of shares of Common Stock entitled to receive such distribution times the number of shares of Common Stock outstanding on such date, then, and in each such case, immediately after the close of business on such date for determination, the 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 peer share of the Common Stock on the date fixed for such determination less an amount equal to the quotient of (x) the excess of such combined amount over such 12.5% 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. -29- (6) In case a tender or exchange offer made by the Company or any subsidiary of the Company for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders (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 (I) 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 of its subsidiaries 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 (II) the aggregate amount of any distributions to all holders of the Company's Common Stock made exclusively in cash within 12 months preceding the expiration of such tender or exchange offer and in respect of which no adjustment pursuant to paragraph (5) of this Section or this paragraph (6) has been made, exceeds 12.5% 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) at the Expiration Time less (B) the amount of cash plus the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender 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 (i) a distribution of such securities other than Common Stock to all holders of -30- 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 (ii) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior 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 becomes effective" or "the day upon which such combination becomes effective", as the case may be, and "the day upon which such subdivision 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 Stock Purchase 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 (l), (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. (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. -31- (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 (any such event, a "Reorganization Event"), the Settlement Rate will be adjusted to provide that each Holder of Units will receive on the Stock Purchase 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 Stock Purchase 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 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 Unit Agent an agreement supplemental hereto providing that the Holders of each Outstanding Unit 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. 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 Unit 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 -32- (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 Units of the occurrence of such event and a statement in reasonable detail setting forth the method by which the adjustment to the Settlement Rate was determined and setting forth the adjusted Settlement Rate. (b) The Unit Agent shall not at any time be under any duty or responsibility to any holder of Units 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 Unit 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 Unit Agent makes no representation with respect thereto. The Unit 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. 5.8 NO FRACTIONAL SHARES. No fractional shares or scrip representing fractional shares of Common Stock shall be issued or delivered upon settlement on the Stock Purchase Date. If Unit 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 Unit Certificates so surrendered. Instead of any fractional share of Common Stock which would otherwise be deliverable upon settlement of any Purchase Contracts on the Stock Purchase Date, the Company, through the Unit Agent, shall make a cash payment in respect of such fractional interest in an amount equal to such fraction times the Applicable Market Value. The Company shall provide the Unit Agent from time to time with sufficient funds to permit the Unit Agent to make all cash payments required by this Section 5.8 in a timely manner. 5.9 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; 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 Unit 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 Unit Certificate surrendered in respect of the Purchase Contracts evidenced thereby, other than in the name of the Unit Agent, as custodian for such Holder, and the Company shall not be required to issue or deliver such share certificates or Unit 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. -33- 5.10 TERMINATION EVENT; NOTICE. The Purchase Contracts and the obligations and rights of the Company and the Holders thereunder, including, without limitation, all obligations and rights to pay or receive any accrued or deferred Contract Fees or to settle such Purchase Contracts pursuant to this Article Five, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Unit Agent or the Company, if, on or prior to the Stock Purchase Date, a Termination Event shall have occurred. Upon the occurrence of a Termination Event, the Company shall give written notice to the Unit Agent, the Collateral Agent and the Holders, at their addresses as they appear in the Unit Registers. Upon and after the occurrence of a Termination Event, the provisions of this Article Five (other than this Section 5.10) shall automatically terminate and be of no further force or effect, and the Unit Certificates shall thereafter represent only the right to receive the Pledged Securities forming a part of the Units theretofore evidenced thereby in accordance with the provisions of Section 4.2 and the Pledge Agreement. 6. REMEDIES. 6.1 UNCONDITIONAL RIGHTS OF HOLDERS. Notwithstanding any other provision in this Agreement, the Holder of any Unit shall have the right, which is absolute and unconditional, to purchase Common Stock pursuant to the Purchase Contract underlying such Unit and to receive payment of Contract Fees, if any, payable by the Company to such Holder with respect to such Purchase Contract and, in each such case, to institute suit for the enforcement of any such right, and such rights shall not be impaired without the consent of such Holder. 6.2 RESTORATION OF RIGHTS AND REMEDIES. If any Holder of Units 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. 6.3 RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise provided with respect to the replacement of mutilated, destroyed, lost or stolen Unit Certificates in the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the Holders of Units 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. 6.4 DELAY OR OMISSION NOT WAIVER. No delay or omission of any Holder to exercise any right or remedy 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. -34- 6.5 UNDERTAKING FOR COSTS. All parties to this Agreement agree, and each Holder of any Unit by his acceptance of the Unit Certificate evidencing such Unit 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 Unit Agent for any action taken, suffered or omitted by it as Unit 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 Unit Agent, to any suit instituted by any Holder of Units, or group of Holders, holding in the aggregate more than 10% of the Outstanding Units, or to any suit instituted by any Holder of Units for the enforcement of payments due in respect of Pledged Securities or Contract Fees on Purchase Contracts underlying such Units on or after the respective due dates therefor, or for enforcement of the right to purchase shares of Common Stock under the Purchase Contracts constituting a part of such Units. 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 Unit Agent or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted. 7. THE UNIT AGENT. 7.1 CERTAIN DUTIES AND RESPONSIBILITIES.

Each Stripped Unit represents the right to purchase Common Stock under a Purchase Contract with AirTouch Communications, Inc., a Delaware corporation (the "Company"), together with ownership of the Treasury Securities pledged to secure the obligations referred to in (a) below, subject to (a) the obligations owed to the Company under such Purchase Contract and (b) the pledge arrangements securing the foregoing obligations. Each Purchase Contract evidenced hereby is governed by a Master Unit Agreement, dated as of __________, 199_ (the "Master Unit Agreement"), between the Company and _________________, as unit agent (herein called the "Unit Agent"). All terms used herein which are defined in the Master Unit Agreement have the meanings set forth therein. The Pledge of the Pledged Securities evidenced hereby is governed by the Pledge Agreement. Reference is hereby made to the Master Unit Agreement and the Pledge Agreement, and any supplemental agreements thereto, for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Unit Agent, the Company, the Collateral Agent and the Holders. The summary contained herein is qualified in its entirety by the provisions of the Principal Agreements, and the Principal Agreements shall govern the rights of the parties to the extent that there is any conflict between such summary and such provisions. Each Purchase Contract evidenced hereby obligates the Holder of this Unit Certificate to purchase, and the Company to sell, on [___________, 2001] (the "Stock Purchase Date"), at a price equal to $ (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 Stock Purchase Date there shall have occurred a Termination Event. The "Settlement Rate" is equal to (a) if the Applicable Market Value (as defined in the Master Unit Agreement) is greater than or equal to $_______ (the "Threshold Appreciation Price"), of a share of Common Stock per Purchase Contract, (b) if the Applicable Market Value is less than the Threshold Appreciation Price but is greater than the Stated Amount, a fractional share of Common Stock per Purchase Contract equal to the Stated Amount divided by the Applicable Market Value (rounded to the nearest 1/10,000th of a share or, if there is no nearest 1/10,000th of a share, rounded downward to the nearest 1/10,000th of a share) and (c) if the Applicable Market Amount is less than or equal to the Stated Amount, one share of Common Stock per Purchase Contract, in each case subject to adjustment as provided in the Master Purchase Agreement. No fractional B-1 shares of Common Stock will be issued upon settlement of Purchase Contracts. The purchase price for the shares of Common Stock to be purchased pursuant to each Purchase Contract evidenced hereby, if not paid by 10:00 a.m., New York City time, on the Stock Purchase Date, shall be paid by application of payments received by the Company on the Stock Purchase Date from the Collateral Agent pursuant to the Pledge Agreement in respect of the Pledged Securities pledged to secure such Holder's obligations under such Purchase Contract. The Purchase Contracts and the obligations and rights of the Company and the Holders thereunder, including, without limitation, the rights and obligations to receive and pay accrued or deferred Contract Fees, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Unit Agent or the Company, if, on or prior to the Stock Purchase Date, a Termination Event shall have occurred. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Pledged Securities from the Pledge.

For so long as the Purchase Contract underlying a Stripped Unit remains in effect, such Stripped Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Stripped Unit in respect of the Pledged Securities and Purchase Contract constituting such Stripped Unit may be transferred and exchanged only as an integrated Stripped Unit.
