If any record - 18 - date is set pursuant to this Section 1.4(e), the Holders of the Outstanding Units on such record date, and no other Holders, shall be entitled to take the relevant action with respect to the Units 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 Record Date Expiration Time (as defined in Section 1.4(f)) by Holders of the requisite number of Outstanding Units on such record date. Nothing in this Section 1.4(e) 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 Section 1.4(e) (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 Section 1.4(e) 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. Promptly after any record date is set pursuant to this Section 1.4(e), the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Record Date Expiration Time to be given to the SQUARZ Agent in writing and to each Holder in the manner set forth in Section 1.6.

Notwithstanding the foregoing, no Record Date Expiration Time shall be later than the 180th day after the applicable record date. Section 1.5 Notices.

(b) A payment in respect of any Substitute Pledged Treasuries or Initial Pledged Treasuries shall, subject to receipt thereof by the SQUARZ Agent from the Collateral Agent as provided by the terms of the Pledge Agreement, be paid to the Company to be applied against the obligations of the Holder to make Underlying Warrant Installment Payments hereunder, but only to the extent permitted by the Pledge Agreement.

(b) Upon the written request of the Holders of SQUARZ on such record date, the SQUARZ 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 Pledged Notes as to which any particular voting instructions are received.

Each Holder of a Unit, by its acceptance thereof: (a) irrevocably authorizes the SQUARZ Agent to enter into and perform its obligations under the related Unit on its behalf as its attorney-in-fact (including the execution of Certificates on behalf of such Holder); (b) agrees to be bound by the terms and provisions of such Units; (c) covenants and agrees to perform its obligations under such Units; (d) consents to the provisions hereof; (e) irrevocably authorizes the SQUARZ Agent as its agent and attorney-in-fact to enter into and perform the Pledge Agreement on its behalf; and (f) consents to and agrees to be bound by the Pledge of the Collateral in support of such Holder's obligation to make Underlying Warrant Installment Payments as required herein. Section 5.2 UNDERLYING WARRANT. (a) Subject to Section 5.4, each Unit shall, at any time on or prior to the Underlying Warrant Termination Date, entitle the Holder thereof, at the Holder's option, to purchase and to require the Company to sell, in consideration of the payment of the Underlying Warrant Exercise Price, either, at the Holder's election, that fraction of a fully paid and non-assessable share of Berkshire Class A Common Stock equal to the Class A Exchange Ratio or that number of fully paid and non-assessable shares of Berkshire Class B Common Stock equal to the Class B Exchange Ratio, in each case subject to adjustment as provided in Section 5.8. The right to purchase Berkshire Common Stock established by this Section 5.2(a), and the obligation to make Underlying Warrant Installment Payments as provided in Section 5.3, subject to the terms and conditions set forth herein, are collectively referred to herein as the "Underlying Warrant." (b) Upon the exercise of one or more Underlying Warrants in accordance with Sections 5.4 and 5.5, for which the Holder elected to receive Berkshire Class A Common Stock, such Holder will receive: (i) that whole number of shares of Berkshire Class A Common Stock equal to the product of the aggregate number of Underlying Warrants such Holder is exercising multiplied by the Class A Exchange Ratio, with the product thereof (if not a whole number) then being rounded down to the nearest whole number (the difference between the product before rounding and such nearest whole number being the "Class A Stub"); plus - 37 - (ii) that whole number of shares of Berkshire Class B Common Stock equal to the product of the Class A Stub multiplied by 30, with the product thereof (if not a whole number) being rounded down to the nearest whole number (the difference between the product before rounding and such nearest whole number being the "Class B Stub"); plus (iii) an amount in cash equal to the product of the Closing Price of one share of Berkshire Class B Common Stock on the date of exercise multiplied by the Class B Stub. (c) Upon the exercise of one or more Underlying Warrants in accordance with Sections 5.4 and 5.5, for which the Holder elected to receive Berkshire Class B Common Stock, such Holder will receive that whole number of shares of Berkshire Class B Common Stock equal to the product of the aggregate number of Underlying Warrants such Holder is exercising multiplied by the Class B Exchange Ratio; provided, that in lieu of any fractional shares, the Holder will be paid an amount in cash equal to the product of the Closing Price of one share of Berkshire Class B Common Stock on the date of exercise multiplied by such fractional share. (d) A Holder (or its appropriate participant, as applicable) may provide multiple elections with respect to its aggregate Underlying Warrants exercised on any particular day, provided that only one election shall be made for any one Underlying Warrant. (e) In the event that the Underlying Warrant Maturity Date, the Underlying Warrant Early Expiration Date or an Underlying Warrant Cancellation Date is not a Business Day, then such maturity, early expiration or cancellation will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of such delay), except that, if such Business Day is in the next succeeding calendar year, such maturity, early expiration or cancellation shall be effective on the immediately preceding Business Day, in each case, with the same force and effect as if effective on such date. The date of exercise of an Underlying Warrant must be a Business Day. Section 5.3 UNDERLYING WARRANT INSTALLMENT PAYMENTS. (a) Each Holder of a Unit, by its acceptance thereof, covenants and agrees that it will timely make Underlying Warrant Installment Payments on each such Unit on each Underlying Warrant Installment Payment Date until the Underlying Warrant Termination Date. (b) Underlying Warrant Installment Payments will accrue from and including the most recent Underlying Warrant Installment Payment Date (or, for the Underlying Warrant Installment Payment due on November 15, 2002, from and including May 15, 2002), to but excluding the date of payment. The amount of any Underlying Warrant Installment Payment payable for any full semi-annual period will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of any Underlying Warrant Installment Payment payable for any period shorter than a full semi-annual period will be computed on the basis of 30-day months and, for periods of less than a month, the actual number of days elapsed per 30-day month. In the event that any Underlying Warrant Installment Payment Date (or other date on which a payment for the Underlying Warrant is payable) is not a Business Day, then - 38 - payment of amounts payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case, with the same force and effect as if made on such date. (c) Each Holder of a Unit, by its acceptance thereof, covenants and agrees that, to the extent and in the manner provided in Section 4.1 and the Pledge Agreement (but subject to the terms thereof), all payments in respect of the Initial Pledged Treasuries, the Substitute Pledged Treasuries, and payments on or for the Pledged Notes (other than payments of principal thereof), if applicable, shall be received by the Collateral Agent on behalf of the Company and paid to the SQUARZ Agent, to make the Underlying Warrant Installment Payments to the Company; provided, however, that if, as of any Underlying Warrant Installment Payment Date, the amount received from interest payments on the Pledged Notes and amount received in respect of the Initial Pledged Treasuries and the Substitute Pledged Treasuries exceeds the Underlying Warrant Installment Payment due on such date, such excess amount will be distributed to the Holders of the SQUARZ (to the extent of the excess received from the Pledged Notes and Initial Pledged Treasuries) and Stripped SQUARZ (to the extent of the excess received from the Substitute Pledged Treasuries and Initial Pledged Treasuries) in each case, on a pro rata basis. (d) Upon transfer of a Unit, the transferee thereof shall be bound (without the necessity of any other action on the part of such transferee) by the terms of this Agreement, the SQUARZ or Stripped SQUARZ and the Pledge Agreement. (e) If a Holder fails to make an Underlying Warrant Installment Payment in full and on time (including as a result of the application of withholding or backup withholding for taxes), the applicable Underlying Warrant will become null and void; provided, that if the Underlying Warrant Installment Payment Date was a date on which the Company defaulted in the payment of interest on the Notes, such Holder will automatically have five Business Days from the Underlying Warrant Installment Payment Date to pay such Underlying Warrant Installment Payment in cash until the Underlying Warrant is deemed cancelled. (f) Upon an Underlying Warrant Early Expiration Date, each Holder will be released from the obligation to make Underlying Warrant Installment Payments that would otherwise accrue and be owing in respect of an Underlying Warrant that has expired, other than Underlying Warrant Installment Payments accrued to (but not including) the Underlying Warrant Early Expiration Date. (g) The Company will have no recourse against any Holder for a failure to timely make Underlying Warrant Installment Payments, other than recourse against the Collateral to the extent provided in the Pledge Agreement. - 39 - Section 5.4 EXERCISE OF UNDERLYING WARRANT. (a) A Holder may exercise the Underlying Warrant at any time at or prior to the earlier to occur of (i) 5:00 p.m., New York City time, on the Underlying Warrant Maturity Date, and (ii) 5:00 p.m., New York City time, on the Underlying Warrant Early Expiration Date. (b) To exercise an Underlying Warrant (in whole but not in part), a Holder (or its appropriate participant, if applicable) must, no later than 5:00 p.m., New York City time, on the proposed date of exercise: (i) surrender to the SQUARZ Agent the Certificate representing the Unit that contains the Underlying Warrant to be exercised (or cause a book-entry transfer of such Unit to the SQUARZ Agent); (ii) properly complete, execute, and deliver to the SQUARZ Agent an election of exercise substantially in the form of Exhibit E (or in any other form that may be agreed to between the Company and the SQUARZ Agent), or an election of exercise for Net Share Settlement in a form reasonably acceptable to the SQUARZ Agent and the Company if, pursuant to Section 5.5(b), the Holder is required or permitted to use the Net Share Settlement procedure; (iii) if the Unit that contains the Underlying Warrant to be exercised was received in a transaction exempt from the registration requirements of the Securities Act, furnish to the SQUARZ Agent such certifications, opinions of counsel, or other information as the Company may reasonably require to confirm that the proposed exercise of the Underlying Warrant and the subsequent issuance of Berkshire Common Stock is being made pursuant to an exemption from the registration requirement under the Securities Act; and (iv) comply with Section 5.5. Section 5.5 SETTLEMENT AND PAYMENT OF UNDERLYING WARRANT EXERCISE PRICE. (a) Cash Settlement. (i) A Holder electing to exercise an Underlying Warrant must pay in respect of each such Underlying Warrant on or prior to the date of exercise: (1) the Underlying Warrant Exercise Price; (2) if such date of exercise is an Underlying Warrant Installment Payment Date, the Underlying Warrant Installment Payment that would otherwise be due on such date in respect of such Underlying Warrant; and (3) if such date of exercise is not an Underlying Warrant Installment Payment Date, a payment equal to the next scheduled Underlying Warrant Installment Payment, or if a Required Acceleration Event has occurred, - 40 - a payment equal to the accrued Underlying Warrant Installment Payment to but excluding the Underlying Warrant Early Expiration Date. (ii) Such payment must be made to the SQUARZ Agent prior to 5:00 p.m., New York City time, on the proposed date of exercise in lawful money of the United States by certified or official bank check or wire transfer to an account designated by the SQUARZ Agent or the Company or, at the option of the Company, through the Depositary; provided, however, if the date of exercise is an Underlying Warrant Installment Payment Date, the Underlying Warrant Installment Payment will be made from application of the proceeds of the Collateral. All such monies will be paid to the Company on the date of exercise in settlement of the exercise of the Underlying Warrant in accordance with the terms of this Agreement and the Pledge Agreement. (iii) Notwithstanding anything to the contrary in this Section 5.5(a), if the Holder of a SQUARZ exercising an Underlying Warrant also participates in a Remarketing of the Pledged Notes contained in such SQUARZ, such Holder may elect in the Remarketing Election Form delivered to the SQUARZ Agent on or prior to 5:00 p.m. New York City time, on the fifth Business Day prior to the Remarketing Date (or, if such Holder has previously elected to participate in a Remarketing, in a supplemental Remarketing Election Form) to have the proceeds of a Successful Remarketing of such Pledged Notes (or the proceeds of the exercise of a Put subsequent to a Failed Remarketing) applied to the payment of the Underlying Warrant Exercise Price. Holders of SQUARZ electing to apply the proceeds of a Remarketing to the Underlying Warrant Exercise Price must also designate that if the Remarketing fails they will require the Company to repurchase their Notes and apply the proceeds to the Underlying Warrant Exercise Price. Such elections shall be irrevocable as to such Holder's participation in the Remarketing, but shall be revocable as to the election by such Holder to exercise the Underlying Warrant and/or apply such proceeds to the payment of the Underlying Warrant Exercise Price at any time prior to 5:00 p.m. New York City time, on the Underlying Warrant Early Expiration Date or the Underlying Warrant Maturity Date, as applicable. Such a revocation must be effected in a writing actually received at the Corporate Trust Office prior to 5:00 p.m. New York City time, on the Underlying Warrant Early Expiration Date or the Underlying Warrant Maturity Date, as applicable. Upon such revocation, the Remarketing Agent shall distribute the proceeds of any Successful Remarketing in accordance with this Agreement and the Pledge Agreement for further distribution to the Holder pursuant to Section 4.6 of the Pledge Agreement. (iv) No Holders will be permitted, at any time, to tender Notes in consideration of the payment of the Underlying Warrant Exercise Price or an Underlying Warrant Installment Payment. (b) Net Share Settlement. (i) Notwithstanding anything in Section 5.5(a) to the contrary, if (x) at the time of exercise of an Underlying Warrant there is not an effective registration statement under the Securities Act registering the shares of Berkshire Common Stock issuable upon exercise of the Underlying Warrant and (y) the shares of Berkshire - 41 - Common Stock issued pursuant to this Section 5.5(b) would not be "restricted securities" under Rule 144, the Holder, in exercising its Underlying Warrants, shall be required to effect a Net Share Settlement (and will not be permitted to effect a Cash Settlement). (ii) Notwithstanding anything in Section 5.5(a) to the contrary, if there has been a Failed Remarketing and the Holder of a SQUARZ exercised its right to Put the Pledged Note contained in such SQUARZ but the Company has not timely paid the full Repurchase Price of such Note, such Holder may elect to effect a Net Share Settlement. (iii) Any Holder of a Unit required or entitled to elect a Net Share Settlement will receive, upon compliance with Section 5.4(b)(i)-(iii), that number of shares of Berkshire Class B Common Stock equal to the quotient of (x) the product of (i) the Average Market Value multiplied by the Class B Exchange Ratio, minus (ii) the Underlying Warrant Exercise Price, divided by (y) the Average Market Value, and then rounding such quotient down to the nearest whole number. A Holder (unless it specifies otherwise) exercising multiple Underlying Warrants simultaneously will receive that number of shares of Berkshire Class B Common Stock equal to the product of the above quotient and the number of Underlying Warrants being exercised, rounded down to the nearest whole number. No fractional shares will be issued in conjunction with a Net Share Settlement, and such Holder (or its appropriate participant, if applicable) will receive a cash payment equal to the amount of fractional Berkshire Class B Common Stock multiplied by the Average Market Value of a share of Berkshire Class B Common Stock in lieu of such a fractional share. (iv) The effective date of exercise of an Underlying Warrant by Net Share Settlement will be the Business Day on which the Holder complies with the requirements of Section 5.4 and Section 5.5, notwithstanding the fact that the Average Market Value will not begin to be calculated until the Trading Day immediately following such date. Upon the exercise of an Underlying Warrant by Net Share Settlement, the exercising Holder (or its appropriate participant, if applicable) must tender to the Company on the applicable date of exercise, an amount equal to the next scheduled Underlying Warrant Installment Payment; provided, however, if such date on which such Underlying Warrant is exercised is subsequent to a Required Acceleration Event, such payment shall instead equal the accrued Underlying Warrant Installment Payment to but excluding the Underlying Warrant Early Expiration Date. If such payment is not timely received from such Holder, such exercise of such Underlying Warrant will not be effective; provided, however, that nothing in this paragraph (iv) will prevent the Holder of such Underlying Warrant from effecting a later exercise. Section 5.6 Cancellation of Unit, Payment of Settlement Amounts and Issuance of Shares of Berkshire Common Stock Upon Exercise of Underlying Warrant. (a) Subject to Sections 5.4 and 5.5 (including the receipt by the SQUARZ Agent of a Unit in connection with the exercise of the Underlying Warrant contained therein and of the Underlying Warrant Exercise Price and the Underlying Warrant Installment Payment (or accrued portion thereof) due upon exercise), the SQUARZ Agent will, on the effective date of an exercise of an Underlying Warrant, - 42 - (i) cancel such Unit; provided, however, that if the Unit is evidenced by a Certificate not all of the Underlying Warrants under which are exercised, the SQUARZ Agent shall authenticate, execute, and deliver for the exercising Holder a Certificate evidencing the whole Units remaining after exercise of the Underlying Warrants; (ii) pay the Underlying Warrant Exercise Price and the Underlying Warrant Installment Payment (or accrued portion thereof) to the Company; (iii) if such Unit was a SQUARZ, instruct the Collateral Agent to release a Pledged Note from the Pledge and Transfer such Note to the SQUARZ Agent, free and clear of the Pledge, on behalf of the exercising Holder (or its applicable participant, if applicable) for each Unit exercised; (iv) if such Unit was a Stripped SQUARZ, instruct the Collateral Agent to Transfer to the SQUARZ Agent, on behalf of the exercising Holder (or its applicable participant) its remaining Substitute Pledged Treasuries Interest, if any, subject to Section 5.6(c), free and clear of the Pledge; (v) instruct the Collateral Agent to Transfer, free and clear of the Pledge, to the SQUARZ Agent, on behalf of the exercising Holder (or its appropriate participant, if applicable) its remaining Initial Pledged Treasuries Interest, if any, subject to Section 5.6(c); (vi) if such Unit was a SQUARZ, instruct the Indenture Trustee to authenticate and deliver to the SQUARZ Agent, on behalf of the exercising Holder (or its applicable participant, if applicable) a Note registered in the name of the exercising Holder for each Unit exercised (which Note shall be a Class B Note, if the effective date of exercise is more than 90 days prior to the next following Scheduled Repurchase Date, or a Class C Note, if the effective date of exercise is not more than 90 days prior to the next following Scheduled Repurchase Date, or a Class A Note, if the effective date of exercise is on or after February 14, 2006); and (vii) subject to Section 5.6(c), Transfer to such Holder (A) the shares of Berkshire Common Stock issuable to it upon such exercise, (B) the Class A Note, Class B Note, Class C Note, or any remaining Substitute Pledged Treasuries Interest held for the benefit of such Holder, and (C) any remaining Initial Pledged Treasuries Interest held for the benefit of such Holder. (b) Upon its receipt of payment in full of (x) the Underlying Warrant Exercise Price (either pursuant to a Cash Settlement or a Net Share Settlement) pursuant to an exercise of an Underlying Warrant, and (y) any Underlying Warrant Installment Payment (or portion thereof) then due, the Company shall issue and deposit with the SQUARZ Agent, for the benefit of the exercising Holder of the Underlying Warrant, one or more certificates representing the newly issued shares of Berkshire Common Stock registered in the name of such Holder. (c) If a Holder (or its appropriate participant, if applicable) exercises the Underlying Warrant of a number of Units that is not an integral multiple of 80, the SQUARZ - 43 - Agent shall instruct the Collateral Agent, and the Collateral Agent will, distribute to such Holder (or its appropriate participant) (i) Notes constituting a part of such Units, and (ii) any Initial Pledged Treasuries and/or Substitute Pledged Treasuries constituting a part of such Units, in integral multiples of $1,000 face amount and retain the remainder of such Initial Pledged Treasuries and Substitute Pledged Treasuries for such Holder's (or its appropriate participant's) benefit (free of the Pledge to the Company) and distribute to such Holder the proceeds thereof as they mature, all in accordance with Section 4.5(e) of the Pledge Agreement. Section 5.7 No Fractional Shares. Notwithstanding anything to the contrary herein, no fractional shares or scrip representing fractional shares of Berkshire Common Stock shall be issued or delivered pursuant to the exercise of any Underlying Warrant. The Company shall provide the SQUARZ Agent from time to time with sufficient funds to permit the SQUARZ Agent to make all cash payments required by Sections 5.2(b) and (c) in a timely manner. Section 5.8 Anti-Dilution Adjustments. The Exchange Ratios shall be subject to adjustment from time to time as follows: (a) Adjustments for Dividends, Distributions, Stock Splits, Etc. (i) Stock Dividends. In case the Company shall pay or make a dividend or other distribution on shares of any class of the Company's capital stock payable in Berkshire Common Stock, the Class A Exchange Ratio, as in effect at the close of business on the date fixed for the determination of stockholders entitled to receive such dividend or other distribution, shall be adjusted so as to equal the number determined by dividing the Class A Exchange Ratio by a fraction of which: (1) the numerator shall be the sum of (x) the product of the number of shares of Berkshire Class A Common Stock times 30, plus (y) the number of shares of Berkshire Class B Common Stock, in each case outstanding at the close of business on the date fixed for such determination, and (2) the denominator shall be the sum computed in clause (1) plus (x) (if such dividend or distribution is paid in shares of Berkshire Class A Common Stock) the total number of shares constituting such dividend or other distribution times 30, and plus (y) (if such dividend or distribution is paid in shares of Berkshire Class B Common Stock) 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. If, after any such date fixed for determination, any such dividend or other distribution is not in fact paid, the Class A Exchange Ratio shall be immediately readjusted, effective as of the date the Company (or its Board of Directors) determines not to pay such dividend or other distribution, to the Class A Exchange Ratio that would have been in effect if such determination date had not been fixed. For the purposes of this paragraph (i), the number of shares of Berkshire Common Stock at the time outstanding shall not include shares held in the treasury of the Company, but shall include any shares issuable in - 44 - respect of any scrip certificates issued in lieu of fractions of shares of Berkshire Common Stock. The Company will not pay any dividend or make any distribution on shares of Berkshire Common Stock held in the treasury of the Company. (ii) Stock Splits; Reverse Splits. In case outstanding shares of Berkshire Class A Common Stock shall be subdivided or split into a greater number of shares of Berkshire Class A Common Stock, the Class A Exchange Ratio 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 Berkshire Class A Common Stock shall be combined into a smaller number of shares of Berkshire Class A Common Stock, the Class A Exchange Ratio 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. (iii) Stock Purchase Rights. In case the Company shall issue rights, options or warrants to all holders of Berkshire Common Stock (which rights, options or warrants are not available on an equivalent basis to Holders of the Units upon exercise of the Underlying Warrants comprising part of such Units) entitling them to subscribe for or purchase shares of a class of Berkshire Common Stock at a price per share less than the Closing Price of the applicable class of Berkshire Common Stock on the date fixed for the determination of stockholders entitled to receive such rights, options or warrants (other than (x) pursuant to a dividend reinvestment, share purchase or similar plan), the Class A Exchange Ratio in effect at the opening of business on the day following the date fixed for such determination shall be adjusted so as to equal the number determined by dividing the Class A Exchange Ratio by a fraction, (1) the numerator of which shall be the sum of (w) the product of the number of shares of Berkshire Class A Common Stock outstanding at the close of business on the date fixed for such determination times 30 plus (x) the number of shares of Berkshire Class B Common Stock outstanding at the close of business on the date fixed for such determination plus (y) (if the offer relates to Berkshire Class A Common Stock) the product of the number of shares of Berkshire Class A Common Stock which the aggregate of the offering price of the total number of shares of Berkshire Class A Common Stock so offered for subscription or purchase would purchase at the applicable Closing Price times 30 plus (z) (if the offer relates to Berkshire Class B Common Stock) the number of shares of Berkshire Class B Common Stock which the aggregate of the offering price of the total number of shares of Berkshire Class B Common Stock so offered for subscription or purchase would purchase at the applicable Closing Price, and (2) the denominator of which shall be the sum of (w) the product of the number of shares of Berkshire Class A Common Stock outstanding at the close of business on the date fixed for such determination times 30 plus (x) the number of shares of Berkshire Class B Common Stock outstanding at the - 45 - close of business on the date fixed for such determination plus (y) (if the offer relates to Berkshire Class A Common Stock) the number of shares of Berkshire Class A Common Stock so offered for subscription or purchase times 30 plus (z) (if the offer relates to Berkshire Class B Common Stock) the number of shares of Berkshire Class B 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. If, after any such date fixed for determination, any such rights, options or warrants are not in fact issued, or are not exercised prior to the expiration thereof, the Class A Exchange Ratio shall be immediately readjusted, effective as of the date such rights, options or warrants expire, or the date the Company (or its Board of Directors) determines not to issue such rights, options or warrants, to the Class A Exchange Ratio that would have been in effect if such rights, options or warrants had never been granted or such determination date had not been fixed, as the case may be. For the purposes of this paragraph (iii), the number of shares of Berkshire Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Berkshire Common Stock. The Company shall not issue any such rights, options or warrants in respect of shares of Berkshire Common Stock held in the treasury of the Company. (iv) Debt or Asset Distributions. In case the Company shall, by dividend or otherwise, distribute to all holders of Berkshire Common Stock evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to in paragraphs (i) or (iii) of this Section 5.8(a), any dividend or distribution paid exclusively in cash, any distribution of shares of Subsidiary Common Stock referred to in paragraph (vii) of this Section 5.8(a), and any dividend, shares of capital stock of any class or series, or similar equity interests or distributions made in connection with a reclassification, change, consolidation, sale or conveyance involving the Company that results in a change in the consideration received upon the exercise of an Underlying Warrant), the Class A Exchange Ratio shall be adjusted so that the same shall equal the number determined by dividing the Class A Exchange Ratio 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, (1) the numerator of which shall be the Closing Price of the Berkshire Class A 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) of the portion of the assets or evidences of indebtedness so distributed applicable to one share of Berkshire Class A Common Stock, and (2) the denominator of which shall be the Closing Price of the Berkshire Class A Common Stock on the date fixed for such determination, - 46 - 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 (iv) is applicable, paragraph (iii) of this Section 5.8(a) shall not be applicable. (v) Cash Distributions. In case the Company shall, by dividend or otherwise, distribute to all holders of its Berkshire Common Stock cash (excluding any cash that is distributed in a Reorganization Event to which Section 5.8(b) applies or as part of a distribution referred to in paragraph (iv) or (vii) of this Section 5.8(a)) in an aggregate amount that, combined together with (x) the aggregate amount of any other distributions to all holders of its Berkshire 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 (v) or paragraph (vi) of this Section 5.8(a) has been made and (y) the aggregate of any cash plus the fair market value as of the date of the expiration of any tender or exchange offer referred to in paragraph (vi) (as determined by the Board of Directors, whose determination shall be conclusive) of consideration paid in respect of any tender or exchange offer by the Company or any of its subsidiaries for all or any portion of the Berkshire Common Stock concluded within the 12 months preceding the date of payment of such distribution and in respect of which no adjustment pursuant to this paragraph (v) or paragraph (vi) of this Section 5.8(a) has been made, exceeds 5% of the sum of (x) the product of the Closing Price of the Berkshire Class A Common Stock on the date for the determination of holders of shares of Berkshire Common Stock entitled to receive such distribution times the number of shares of Berkshire Class A Common Stock outstanding on such date plus (y) the product of the Closing Price of the Berkshire Class B Common Stock on the date for the determination of holders of shares of Berkshire Common Stock entitled to receive such distribution times the number of shares of Berkshire Class B Common Stock outstanding on such date (such excess being referred to herein as the "Excess Tender and Cash Amount"), then, and in each such case, immediately prior to the opening of business on the day after the date fixed for the determination of holders of shares of Berkshire Common Stock entitled to receive such distribution, the Class A Exchange Ratio shall be increased so that the same shall equal the number determined by dividing the Class A Exchange Ratio 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 (1) the numerator of which shall be equal to the difference of (x) the sum of (i) the product of the Closing Price of Berkshire Class A Common Stock on the date for the determination of holders of shares of Berkshire Common Stock entitled to receive such distribution multiplied by the number of shares of Berkshire Class A Common Stock outstanding on such determination date plus (ii) the product of the Closing Price of Berkshire Class B Common Stock on such determination date multiplied by the number of shares of Berkshire Class B Common Stock outstanding on such determination date minus (y) the Excess Tender and Cash Amount, and - 47 - (2) the denominator of which shall be equal to the sum of (x) the product of (i) the Closing Price of Berkshire Class A Common Stock on such date of determination multiplied by (ii) the number of shares of Berkshire Class A Common Stock outstanding on such determination date plus (y) the product of (i) the Closing Price of Berkshire Class B Common Stock on such determination date multiplied by (ii) the number of shares of Berkshire Class B Common Stock outstanding on such determination date. (vi) Tender Offers. In case a tender or exchange offer made by the Company or any subsidiary of the Company for all or any portion of the Berkshire 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 (as defined below)) of an aggregate consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive) that combined together with (x) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive), as of the expiration of such tender or exchange offer, of consideration paid 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 Berkshire 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 (v) of this Section 5.8(a) or this paragraph (vi) has been made and (y) the aggregate amount of any distributions to all holders of the Company's Berkshire Common Stock made exclusively in cash within the 12 months preceding the expiration of such tender or exchange offer (excluding any cash that is distributed in a Reorganization Event to which Section 5.8(b) applies or as part of a distribution referred to in paragraph (iv) or (vii) of this Section 5.8(a), and in respect of which no adjustment pursuant to paragraph (v) of this Section 5.8(a) or this paragraph (vi) has been made) (such fair market value of the payment to stockholders of Purchased Shares together with the amounts stated in clauses (x) and (y) above, the "Tender and Cash Amount") exceeds 5% of the sum of (x) the product of the Current Market Price of Berkshire Class A Common Stock times the number of shares of Berkshire Class A Common Stock outstanding (including any tendered shares) as of the last time (the "Expiration Time for Tenders") tenders could have been made pursuant to such tender or exchange offer (as it may be amended) on the Expiration Time for Tenders plus (y) the product of the Current Market Price of Berkshire Class B Common Stock times the number of shares of Berkshire Class B Common Stock outstanding (including any tendered shares) as of the Expiration Time for Tenders, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time for Tenders, the Class A Exchange Ratio shall be adjusted so that the same shall equal the number determined by dividing the Class A Exchange Ratio immediately prior to the close of business on the date of the Expiration Time for Tenders by a fraction (1) the numerator of which shall be equal to the difference of (x) the sum of (i) the product of the Current Market Price of Berkshire Class A Common Stock determined on the date of the Expiration Time for Tenders times the number of shares of Berkshire Class A Common Stock outstanding (including any - 48 - tendered shares) on the Expiration Time for Tenders plus (ii) the product of the Current Market Price of Berkshire Class B Common Stock determined on the date of the Expiration Time for Tenders times the number of shares of Berkshire Class B Common Stock outstanding (including any tendered shares) on the Expiration Time for Tenders minus (y) the Tender and Cash Amount, and (2) the denominator of which shall be equal to the sum of (x) the product of (i) the Current Market Price of Berkshire Class A Common Stock determined on the date of the Expiration Time for Tenders times (ii) the number of shares of Berkshire Class A Common Stock outstanding (including any tendered shares) as of the Expiration Time for Tenders minus the number of shares of Berkshire Class A Common Stock validly tendered and not withdrawn as of the Expiration Time for Tenders plus (y) the product of (i) the Current Market Price of Berkshire Class B Common Stock determined on the date of the Expiration Time for Tenders times (ii) the number of shares of Berkshire Class B Common Stock outstanding (including any tendered shares) as of the Expiration Time for Tenders minus the number of shares of Berkshire Class B Common Stock validly tendered and not withdrawn as of the Expiration Time for Tenders. Shares deemed accepted up to any maximum specified in the terms of the tender or exchange offer are referred to herein as the "Purchased Shares." (vii) Distribution of Subsidiary Common Stock. In case the Company distributes shares of Subsidiary Common Stock to holders of Berkshire Common Stock (but excluding any distributions of evidences of indebtedness or assets referred to in paragraph (iv) of this Section 5.8(a)), the Class A Exchange Ratio in effect on the opening of business on the eleventh Trading Day immediately following the date of such distribution shall be adjusted so as to equal the number determined by dividing the Class A Exchange Ratio by a fraction, (1) the numerator of which shall be the Current Market Price of Berkshire Class A Common Stock determined on such eleventh Trading Day, and (2) the denominator of which shall be the sum of (x) the amount computed in clause (1) plus (y) the Current Subsidiary Market Price multiplied by the number of full shares (if any) of Subsidiary Common Stock distributed with respect to one share of Berkshire Class A Common Stock plus (z) the cash (if any) distributed with respect to one share of Berkshire Class A Common Stock. In any case in which this paragraph (vii) is applicable, paragraph (iv) of this Section 5.8(a) shall not be applicable. (viii) Reclassification. The reclassification of Berkshire Common Stock into securities including securities other than Berkshire Common Stock (other than any reclassification upon a Reorganization Event to which Section 5.8(b) applies) shall be deemed to involve (i) a distribution of such securities other than Berkshire Common - 49 - Stock to all holders of Berkshire 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 (iv) of this Section 5.8(a)), and (ii) a subdivision, split or combination, as the case may be, of the number of shares of Berkshire Common Stock outstanding immediately prior to such reclassification into the number of shares of Berkshire 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 (ii) of this Section 5.8(a)). (ix) Calculation of Adjustments. All adjustments to the Class A Exchange Ratio shall be calculated to the nearest 1/10,000th of a share of Berkshire Class A 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 Class A Exchange Ratio shall be required unless such adjustment would require an increase or decrease of at least one percent therein; provided, 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. Whenever the Class A Exchange Ratio is adjusted as provided herein, the Class B Exchange Ratio shall be adjusted to equal that number which is 30 times the Class A Exchange Ratio. (b) Adjustment for Consolidation, Merger or Other Reorganization Event. (i) In the event of (1) 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 Berkshire 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), (2) any sale, transfer, lease or conveyance to another Person of the property of the Company as an entirety or substantially as an entirety, (3) any statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition), or (4) any liquidation, dissolution or winding up of the Company other than as a result of or after the occurrence of a Required Acceleration Event (any such event, a "Reorganization Event"), each share of Berkshire Common Stock covered by each Underlying Warrant forming a part of a Unit immediately prior to such Reorganization Event shall, after such Reorganization Event, be converted for purposes of the Underlying Warrant into the kind and amount of securities, cash and other property receivable in such Reorganization Event (without any interest thereon, and without any - 50 - right to dividends or distributions thereon which have a record date that is prior to the Underlying Warrant Maturity Date) per share of Berkshire Common Stock by a holder of Berkshire Common Stock that (i) 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 (any such Person, a "Constituent Person"), or an Affiliate of a Constituent Person to the extent such Reorganization Event provides for different treatment of Berkshire Common Stock held by Affiliates of the Company and non-Affiliates, and (ii) 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 Berkshire Common Stock (ignoring for this purpose differences that are mandated by the proportional relationship between Berkshire Class A Common Stock and Berkshire Class B 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). On the Underlying Warrant Maturity Date, the Class A Exchange Ratio then in effect will be applied for determining the amount of such securities, cash or other property to which a Holder of an Underlying Warrant is entitled upon exercise, provided that cash will be paid in lieu of any fractional shares or units of securities or property not divisible into appropriate fractional amounts. (ii) 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 SQUARZ Agent an agreement supplemental hereto providing that the Holder of each Unit shall have the rights provided by this Section 5.8, and the Company shall not be a party to a Reorganization Event in the absence of such a supplemental agreement. 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 5.9 NOTICE OF ADJUSTMENTS AND CERTAIN OTHER EVENTS. (a) Whenever the Class A Exchange Ratio and Class B Exchange Ratio is adjusted as herein provided, the Company shall: (i) forthwith compute the Class A Exchange Ratio and Class B Exchange Ratio in accordance with Section 5.8 and prepare and transmit to the SQUARZ Agent an Officer's Certificate setting forth the adjusted Class A Exchange Ratio and Class B Exchange Ratio, the method of calculation thereof in reasonable detail, and the facts requiring such adjustment and upon which such adjustment is based; and - 51 - (ii) as soon as practicable following the occurrence of an event that requires an adjustment to the Class A Exchange Ratio and Class B Exchange Ratio pursuant to Section 5.8 (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 Class A Exchange Ratio and Class B Exchange Ratio was determined and setting forth the adjusted Class A Exchange Ratio and Class B Exchange Ratio. (b) The SQUARZ 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 Class A Exchange Ratio and Class B Exchange Ratio, 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 SQUARZ Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Berkshire Common Stock, or of any securities or property, that may at the time be issued or delivered with respect to any SQUARZ or Stripped SQUARZ; and the SQUARZ Agent makes no representation with respect thereto. The SQUARZ Agent shall not be responsible for any failure of the Company to issue, transfer or deliver any shares of Berkshire Common Stock pursuant to a SQUARZ or Stripped SQUARZ or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Section 5.10 Charges and Taxes. The Company will pay all stock transfer and similar taxes attributable to the initial issuance and delivery of the shares of Berkshire Common Stock pursuant to the exercise of the Underlying Warrants; provided, 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 Unit or any issuance of a share of Berkshire Common Stock in a name other than that of the registered Holder of a Certificate surrendered in respect of the Units evidenced thereby, other than in the name of the SQUARZ Agent, as custodian for such Holder, and the Company shall not be required to issue or deliver such share certificates or Certificates unless and 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. Section 5.11 Reservation of Shares. The Company has authorized and will reserve for issuance the maximum number of shares of Berkshire Common Stock issuable upon the exercise of all outstanding Underlying Warrants. Such shares of Berkshire Common Stock, when issued and paid for in accordance with the provisions of this Agreement, will be duly and validly issued, fully paid and nonassessable, free of preemptive rights and free from all taxes, liens, charges and security interests. Section 5.12 REQUIRED ACCELERATION EVENT; NOTICE. (a) For purposes of determining whether a Required Acceleration Event has occurred due to the market value of a SQUARZ being less than 95% of its underlying value (each, as more specifically set forth in the definition of Required Acceleration Event), neither the Company nor the SQUARZ Agent shall have any obligation to determine such market value or - 52 - underlying value unless and until requested in writing by a holder of SQUARZ to determine such amounts; provided, however, that the SQUARZ Agent shall thereupon calculate the market value and underlying value, as required, beginning on the first Trading Day following receipt of such notice, provided, further that the SQUARZ Agent shall cease performing such calculation on the first Trading Day on which the market value of the SQUARZ exceeds 95% or more of its underlying value and shall not be required to recommence such calculation until a new notice is received in writing from a holder of SQUARZ. (b) If a Required Acceleration Event occurs, the Company will cause written notice thereof to be given to the Holders as soon as reasonably practicable, but in no event more than 5 Business Days after such Required Acceleration Event has occurred. Such notice will state that a Required Acceleration Event has occurred and that the Underlying Warrants will expire on the 30th day following the giving of notice by the Company that a Required Acceleration Event has occurred (the "Underlying Warrant Early Expiration Date") or on the Underlying Warrant Maturity Date, whichever is earlier. (c) The Underlying Warrants shall terminate without the necessity of any notice or action by any Holder, on the Underlying Warrant Early Expiration Date. Upon and after the Underlying Warrant Early Expiration Date, each unexercised SQUARZ shall thereafter represent a Note and an Initial Pledged Treasuries Interest, and each unexercised Stripped SQUARZ shall thereafter represent a Substitute Pledged Treasuries Interest and an Initial Pledged Treasuries Interest, in each case until released in accordance with the provisions of the Pledge Agreement. Following the Underlying Warrant Early Expiration Date, the SQUARZ Agent will sell (or will instruct the Collateral Agent to sell) the remaining Initial Pledged Treasuries and Substitute Pledged Treasuries, and the SQUARZ Agent shall distribute the net sale proceeds from the Substitute Pledged Treasuries to the holders of the Stripped SQUARZ and the net sale proceeds from the Initial Pledged Treasuries to the holders of Units, in each case, on a pro rata basis as soon as practicable following the Underlying Warrant Early Expiration Date. Section 5.13 CANCELLATION OF UNDERLYING WARRANTS. (a) Each Holder of a SQUARZ shall have the right, on each Scheduled Repurchase Date, provided the Pledged Note is concurrently therewith properly Put in accordance with the terms of the Indenture, to cancel the Underlying Warrant comprising such SQUARZ by notice to the SQUARZ Agent no later than 5:00 p.m. New York City time on the Business Day prior to the Scheduled Repurchase Date (in which case the Holder shall also simultaneously pay to the SQUARZ Agent, for the benefit of the Company, in cash, the Underlying Warrant Installment Payment due on such Scheduled Repurchase Date). (b) If there has been a default by the Company in the payment of interest on the Notes, each Holder shall have the option to cancel its Underlying Warrants, effective on the date of such defaulted interest payment, by notice to the SQUARZ Agent within five Business Days of such default (in which case such Holder will not be obligated to make any further Underlying Warrant Installment Payments due on or after the Underlying Warrant Cancellation Date). If a Holder of SQUARZ does not wish to cancel its Underlying Warrants such Holder shall, within five Business Days of such default, convert such SQUARZ to a Stripped SQUARZ - 53 - as provided herein; provided, that failure to convert shall be deemed to be an exercise of such Holder's option to cancel its Underlying Warrants. (c) Upon the occurrence of a Bankruptcy Event, all Underlying Warrants shall immediately and automatically, without need for any action by the Holder, the SQUARZ Agent or the Company, be cancelled (in which case such Holder will not be obligated to make any further Underlying Warrant Installment Payments due on or after the Underlying Warrant Cancellation Date, whether or not otherwise accrued as of such date). (d) Upon the cancellation of an Underlying Warrant, the Holder thereof shall no longer be required to make Underlying Warrant Installment Payments, and the Collateral shall be returned to the Holders in accordance with the provisions of the Pledge Agreement. Other than for the deemed cancellation upon a Bankruptcy Event, if a Holder cancels a number of Units that is not an integral multiple of 80, the SQUARZ Agent will instruct the Collateral Agent to distribute to such Holder Notes constituting a part of such Units and any Initial Pledged Treasuries and/or Substitute Pledged Treasuries constituting a part of such Units, in integral multiples of $1,000 face amount; provided, however, that the Collateral Agent will retain the remainder of such Initial Pledged Treasuries and Substitute Pledged Treasuries for such Holder's benefit (free of the Pledge to the Company) and distribute to such holder the proceeds thereof as they mature. Upon the occurrence of a Bankruptcy Event, subject to the approval of the bankruptcy court, if required, Notes will be returned to Holders of SQUARZ and Initial Pledged Treasuries and Substitute Pledged Treasuries will be sold by the SQUARZ Agent, with the proceeds from the Substitute Pledged Treasuries to be distributed pro rata to the Holders of the Stripped SQUARZ and the proceeds from the Initial Pledged Treasures to be distributed pro rata to the Holders of Units. (e) Except as set forth in this Section 5.13, Underlying Warrants may not be cancelled by the Holders of the Units. Section 5.14 Reductions in Exercise Price. The Company may make such reductions in the Underlying Warrant Exercise Price as it considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Berkshire 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. The Company shall give at least 15 days notice prior to the date any such reduction becomes effective, and any such reduction shall remain effective for at least 20 days. ARTICLE 6 REMARKETING. Section 6.1 Engagement of Remarketing Agent. Upon the occurrence of a Remarketing Event, the Company shall engage a nationally recognized investment bank (the "Remarketing Agent") pursuant to a Remarketing Agreement substantially in the form of Exhibit H hereto, to (a) determine the Reset Rate and (b) sell the Notes (other than the Notes of Holders - 54 - that have elected not to participate in the remarketing pursuant to the procedures set forth in Section 6.3) (together, a "Remarketing"). Section 6.2 REMARKETING PROCEDURE. (a) The Company shall request, not later than seven nor more than 15 calendar days prior to the Reset Announcement Date, that the Depositary notify its participants holding the SQUARZ or the Separate Notes of the Reset Announcement Date and of the procedures that must be followed if any owner of SQUARZ or Notes wishes to elect not to participate in the remarketing. (b) On the Reset Announcement Date, (i) the Remarketing Agent and the Company shall determine the Applicable Benchmark Treasury and the Remarketing Agent shall determine the Reset Spread and (ii) the Company shall announce the Reset Spread and the Applicable Benchmark Treasury, and cause a notice of the Reset Spread and the Applicable Benchmark Treasury to be published on the Business Day following the Reset Announcement Date by publication in The Wall Street Journal or another daily newspaper in the English language of general circulation in New York City. (c) At no later than 10:00 a.m., New York City time, on the third Business Day immediately preceding the Remarketing Date, the Company and the SQUARZ Agent shall notify the Remarketing Agent of the aggregate principal amount of the Notes (including Pledged Notes and Separate Notes) that will participate in the remarketing (the "Participating Notes"), and the Company shall also give a written notice to the Remarketing Agent as to whether or not there is any limitation under applicable law on the Reset Rate on the Notes, and, if so, the maximum permissible Reset Rate. On the Business Day immediately preceding the Remarketing Date, the Collateral Agent and the SQUARZ Agent, pursuant to the terms of the Pledge Agreement, will deliver to the Remarketing Agent all Notes to be remarketed. (d) Subject to the terms and conditions set forth in the Remarketing Agreement, on the Remarketing Date, the Remarketing Agent shall use commercially reasonable efforts to remarket the Participating Notes with an interest rate equal to the Reset Rate at a price equal to 100.125% of the principal amount of such Notes, plus any accrued and unpaid interest. If, by 4:00 p.m., New York City time, on the Remarketing Date, the Remarketing Agent is unable to remarket all of the Participating Notes at a price of at least 100% of the principal amount of such Notes, plus any accrued and unpaid interest, a "Failed Remarketing" will have occurred. (e) In the event of a Successful Remarketing: (i) By approximately 4:30 p.m., New York City time, on the Remarketing Date the Remarketing Agent will advise: (1) the Depositary, the Indenture Trustee, the SQUARZ Agent and the Company of the Reset Rate determined in the Remarketing and the number of Notes sold in the Remarketing; - 55 - (2) each Person purchasing Notes in the Remarketing, or the appropriate Clearing Agency Participant, of the Reset Rate (if applicable) and the number of Notes such Person is to purchase; and (3) each purchaser of Notes to give instructions to its Clearing Agency Participant to pay the purchase price on the settlement date in same day funds against delivery of the Notes purchased through the facilities of the Depositary; and The proceeds from a Successful Remarketing shall initially be paid to the SQUARZ Agent, to be further paid to the Collateral Agent (to the extent such Notes were Pledged), or paid to Holders of Separate Notes. (f) In the event of a Failed Remarketing: (i) the SQUARZ Agent will give notice of the Failed Remarketing to the Company and all Holders of Notes and SQUARZ in a manner consistent with Section 2.9 prior to the close of business on the Business Day following the Remarketing Date; and (ii) the Remarketing Agent shall promptly return the Participating Notes included in such Failed Remarketing to the SQUARZ Agent, to be further returned by the SQUARZ Agent to their Holders, and in the case of the Pledged Notes, to the Collateral Agent. Section 6.3 ELECTIONS BY HOLDERS. (a) Holders of the SQUARZ or Separate Notes may, by delivery of a completed and executed Remarketing Election Form to the SQUARZ Agent no later than 5:00 p.m., New York City time, on the fifth Business Day immediately preceding the Remarketing Date, elect not to participate in the Remarketing. Any such notice will be irrevocable and may not be conditioned upon the level at which the Reset Rate is established in the Remarketing. Holders of SQUARZ or Separate Notes who have not delivered such a form will be deemed to have agreed to participate in the Remarketing. Holders of SQUARZ will be deemed to have elected to participate in an Acceleration Event Remarketing unless they have tendered on or prior to the fifth Business Day preceding the Remarketing Date cash in an amount equal to the interest on the Pledged Notes that has accrued or will accrue up to (but excluding) the Underlying Warrant Early Expiration Date. (b) Holders of SQUARZ participating in the Remarketing may provide notice by the fifth Business Day preceding the Remarketing Date indicating that they intend to exercise Underlying Warrants in connection with such Remarketing and that they wish the proceeds of a Successful Remarketing (or the proceeds of the Put of their Notes upon a Failed Remarketing pursuant to Section 5.5(a)(iii)) to be applied to the Underlying Warrant Exercise Price. Holders of SQUARZ electing to apply the proceeds of a Successful Remarketing to the Underlying Warrant Exercise Price must also designate that upon a Failed Remarketing they will Put their Notes and apply the proceeds to the Underlying Warrant Exercise Price. If a Holder of SQUARZ has given notice of exercise of an Underlying Warrant and has requested that the - 56 - Remarketing proceeds be applied to the Underlying Warrant Exercise Price, any excess net proceeds will be distributed to the Holder. If a Holder of a SQUARZ participating in the Remarketing does not elect to exercise the Underlying Warrant, the proceeds from a remarketed Note (net of any payment on the Note, exclusive of payment of principal of the Note, that may be applied to the payment of the Underlying Warrant Installment Payment due hereunder) will be distributed to that Holder. Section 6.4 OTHER AGREEMENTS. (a) The right of a Holder to have Notes sold in a Remarketing is limited to the extent that (i) the Remarketing Agent conducts a Remarketing on the Remarketing Date pursuant to the terms of this Agreement and the Remarketing Agreement, (ii) the Remarketing Agent is able to find a purchaser or purchasers for the Notes at a Reset Rate that results in a Successful Remarketing, and (iii) such purchaser or purchasers deliver the purchase price therefor to the Remarketing Agent as and when required. (b) The Company will pay for all costs and expenses incurred in connection with the Remarketing, including the fee paid to the Remarketing Agent.

(d) Whether or not therein expressly so provided, every provision of every Transaction Document relating to the conduct or affecting the liability of or affording protection to the SQUARZ Agent shall be subject to the provisions of this Section 7.1. (e) The SQUARZ Agent is authorized to execute and deliver the Pledge Agreement and a Remarketing Agreement and any supplement thereto in its capacity as SQUARZ Agent.
