The Fair Market Value of any assets or securities that are required to be valued by this Section  3.11 will be determined by the Board of Directors, whose determination will be evidenced by a Board Resolution. The Board of Directors’ determination must be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if the Fair Market Value exceeds fifteen million dollars ($15,000,000).

(C)     Determining Compliance with This Section . For purposes of determining compliance with this Section  3.13 , in the event that an item of Indebtedness (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described in clauses (i)  through (xiv) , inclusive, of Section 3.13(B) , or is entitled to be incurred pursuant to Section 3.13(A) , the Company will be permitted to classify (or later classify or reclassify, in whole or in part, in its sole discretion) such item of Indebtedness in any manner that complies with this Section  3.13 ; provided , however , that Indebtedness under the Term Loan Agreement outstanding on the Issue Date will initially be deemed to have been incurred on the Issue Date pursuant to clause (i)  of Section 3.13(B) . The amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP. Indebtedness of any Person existing at the time such Person becomes a Restricted Subsidiary will be deemed to have been incurred by the Company and the applicable Restricted Subsidiary at the time such Person becomes a Restricted Subsidiary. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock, will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section  3.13 , provided , in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued.

(D)     Anti-Layering Covenant . The Company will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Guarantee on substantially identical terms; provided , however , that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of being secured on a junior priority basis. In addition, the Company will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is secured by Liens that are contractually junior to the Liens securing any other Indebtedness of the Company or such Guarantor unless such Liens are also junior to the Liens securing the Notes and the applicable Guarantee.

(iii)    at least seventy five percent (75%) of the consideration received by the Company or such Restricted Subsidiary from all Asset Sales since the Issue Date, in the aggregate, is in the form of cash (which, for these purposes, will be deemed to include any securities, notes or other obligations received by the Company or any Restricted Subsidiary from such transferee that are, within ninety (90) days of the applicable Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion).

(B)     Permitted Use of the Net Proceeds within 360 Days of Receipt .

(D)     Application of Excess Proceeds .

(i)     Asset Sale Offer . Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 3.14(B) will constitute “ Excess Proceeds .” On the three hundred and sixty first (361st) day after any Asset Sale (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds fifteen million dollars ($15,000,000), then the Company will make an offer (the “ Asset Sale Offer ”) to all Holders to purchase the maximum principal amount of Notes that may be purchased out of the Excess Proceeds, and will notify the Trustee of the same.

(ii)     Asset Sale Repurchase Price . The Asset Sale Repurchase Price for any Note to be repurchased in an Asset Sale Offer is an amount in cash equal to the principal amount of such Note plus accrued and unpaid interest on such Note to, but excluding, the applicable Asset Sale Repurchase Date; provided , however , that if such Asset Sale Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, then (1) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such repurchase, to receive, on or before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Asset Sale Repurchase Date is before such Interest Payment Date); and (2) the Asset Sale Repurchase Price will not include accrued and unpaid interest on such Note to, but excluding, such Asset Sale Repurchase Date. For the avoidance of doubt, if an Interest Payment Date is not a Business Day within the meaning of Section 2.05(C) and such Asset Sale Repurchase Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance with Section 2.05(C) , on the next Business Day to Holders at of the Close of Business on the immediately preceding Regular Record Date; and (y) the Asset Sale Repurchase Price will include interest on Notes to be repurchased from, and including, such Interest Payment Date.

(iii)     Use of any Excess Proceeds Remaining After Asset Sale; Pro-Rata Selection; Effect of Asset Sale Offer . If any Excess Proceeds remain after consummation of such an Asset Sale Offer, then the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, then, subject to any applicable subject to any the Depositary Procedures, the Company will select the Notes to be purchased pro rata. Upon completion of each such Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(E)     Compliance with Applicable Securities Laws . To the extent applicable, the Company will comply with all federal and state securities laws in connection with a Repurchase Upon Asset Sale (including complying with Rules 13e-4 and 14e-1 under the Exchange Act and filing any required Schedule TO, to the extent applicable) so as to permit effecting such Repurchase Upon Asset Sale in the manner set forth in this Indenture.

(ii)    the Company delivers to the Trustee:

(1)    with respect to any Affiliate Transaction, or series of related Affiliate Transactions involving aggregate consideration in excess of five million dollars ($5,000,000), an Officer’s Certificate certifying that such Affiliate Transaction complies with this Section  3.15 ; and

(x)    any transaction with any Initial Holder or any Affiliate or Affiliated Entity of any Initial Holder.

That designation will only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary.

- 70 -

(B)     Designation of Restricted Subsidiaries . The Board of Directors may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided , however , that (i) such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary; and (ii) such designation will only be permitted if (1) such Indebtedness is permitted under Section  3.13 , calculated on a pro forma basis as if such designation had occurred at the beginning of the four (4) quarter reference period; and (2) no Default or Event of Default would be in existence following such designation.

(v)    if the Company does not timely elect a Settlement Method with respect to the conversion of a Note, then the Company will be deemed to have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not constitute a Default or Event of Default);

- 82 -

(vi)    if the Company timely elects Combination Settlement with respect to the conversion of a Note but does not timely notify the Holder of such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of Notes (and, for the avoidance of doubt, the failure to timely send such notification will not constitute a Default or Event of Default); and

(2)    if Cash Settlement applies to such conversion, cash in an amount equal to the sum of the Daily Conversion Values for each VWAP Trading Day in the Observation Period for such conversion; or

(3)    if Combination Settlement applies to such conversion, consideration consisting, subject to Section 5.03(B)(ii) , of (a) a number of shares of Common Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such conversion; and (b) an amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation Period.

(ii)     Cash in Lieu of Fractional Shares . If Physical Settlement or Combination Settlement applies to the conversion of any Note and the number of shares of Common Stock deliverable pursuant to Section 5.03(B)(i) upon such conversion is not a whole number, then such number will be rounded down to the nearest whole number and the Company will deliver, in addition to the other consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such fraction and (2) (x) the Daily VWAP on the Conversion Date for such conversion (or, if

If a Holder converts more than one (1) Note on a single Conversion Date, then the Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and practicable under, the Depositary Procedures) be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder.

(iv)     Notice of Calculation of Conversion Consideration . If Cash Settlement or Combination Settlement applies to the conversion of any Note, then the Company will determine the Conversion Consideration due thereupon promptly following the last VWAP Trading Day of the applicable Observation Period and will promptly thereafter send notice to the Trustee and the Conversion Agent of the same and the calculation thereof in reasonable detail. Neither the Trustee nor the Conversion Agent will have any duty to make any such determination.

(C)     Delivery of the Conversion Consideration . Except as set forth in Sections 5.05(A) , 5.05(C) and 5.08 , the Company will pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder as follows: (i) if Cash Settlement or Combination Settlement applies to such conversion, on or before the third (3rd) (or, if the T+2 Effective Date has occurred by the last VWAP Trading Day of the Observation Period for such conversion, the second (2nd)) Business Day immediately after the last VWAP Trading Day of such Observation Period; and (ii) if Physical Settlement applies to such conversion, on or before the third (3rd) (or, if the T+2 Effective Date has occurred by the Conversion Date for such conversion, the second (2nd)) Business Day immediately after such Conversion Date.

(D)     Deemed Payment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion . If a Holder converts a Note, then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and, except as provided in Section 5.02(D) , the Company’s delivery of the Conversion Consideration due in respect of such conversion will be deemed to fully satisfy and discharge the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding the Conversion Date. As a result, except as provided in Section 5.02(D) , any accrued and unpaid interest on a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, subject to Section 5.02(D) , if the Conversion Consideration for a Note consists of both cash and shares of the Common Stock, then accrued and unpaid interest that is deemed to be paid therewith will be deemed to be paid first out of such cash.

Section 5.04.    R ESERVE AND S TATUS OF C OMMON S TOCK I SSUED UPON C ONVERSION .

(A)     Stock Reserve . At all times when any Notes are outstanding Article 5 , the Company will reserve, out of its authorized but unissued and unreserved shares of Common

- 84 -

Stock, a number of shares of Common Stock sufficient to permit the conversion of all then-outstanding Notes, assuming (x) Physical Settlement will apply to such conversion; and (y) the Conversion Rate is increased by the maximum amount pursuant to which the Conversion Rate may be increased pursuant to Section  5.07 .

(B)     Status of Conversion Shares; Listing . Each Conversion Share, if any, delivered upon conversion of any Note will be a newly issued or treasury share and will be duly and validly issued, fully paid, non-assessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder of such Note or the Person to whom such Conversion Share will be delivered). If the Common Stock is then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will cause each Conversion Share, when delivered upon conversion of any Note, to be admitted for listing on such exchange or quotation on such system.

Section 5.05.    A DJUSTMENTS TO THE C ONVERSION R ATE .

(A)     Events Requiring an Adjustment to the Conversion Rate . The Conversion Rate will be adjusted from time to time as follows:

(i)     Stock Dividends, Splits and Combinations . If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination of the Common Stock (in each case excluding an issuance solely pursuant to a Common Stock Change Event, as to which the provisions set forth in Section  5.08 will apply), then the Conversion Rate will be adjusted based on the following formula:

- 85 -

If any dividend, distribution, stock split or stock combination of the type described in this Section 5.05(A)(i) is declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been declared or announced.

(ii)     Rights, Options and Warrants . If the Company distributes, to all or substantially all holders of Common Stock, rights, options or warrants (other than pursuant to a stockholder rights plan, as to which, for the avoidance of doubt, the provisions set forth in Sections 5.05(A)(iii)(1) and 5.05(E) will apply) entitling such holders, for a period of not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion Rate will be increased based on the following formula:

To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including as a result of such rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion Rate that

- 86 -

would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, option or warrants. To the extent such rights, options or warrants are not so distributed, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the Ex-Dividend Date for the distribution of such rights, options or warrants not occurred.

For purposes of this Section 5.05(A)(ii) , in determining whether any rights, options or warrants entitle holders of Common Stock to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date of the distribution of such rights, options or warrants is announced, and in determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if not cash, to be determined by the Board of Directors.

(iii)     Spin-Offs and Other Distributed Property .

(1)     Distributions Other than Spin-Offs . If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or Property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common Stock, excluding:

(v)    dividends, distributions, rights, options or warrants for which an adjustment to the Conversion Rate is required pursuant to Section 5.05(A)(i) or 5.05(A)(ii) ;

(w)    dividends or distributions paid exclusively in cash for which an adjustment to the Conversion Rate is required pursuant to Section 5.05(A)(iv) ;

(x)    rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent provided in Section 5.05(E) ;

(y)    Spin-Offs for which an adjustment to the Conversion Rate is required pursuant to Section 5.05(A)(iii)(2) ; and

(z)    a distribution solely pursuant to a Common Stock Change Event, as to which the provisions set forth in Section  5.08 will apply,

- 87 -

then the Conversion Rate will be increased based on the following formula:

provided , however , that if FMV is equal to or greater than SP , then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at the same time and on the same terms as holders of Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets, Property, rights, options or warrants that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

To the extent such distribution is not so paid or made, or such rights, options or warrants are not exercised before their expiration (including as a result of being redeemed or terminated), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the distribution, if any, actually made or paid or on the basis of the distribution of only such rights, options or warrants, if any, that were actually exercised, if at all.

- 88 -

(2)     Spin-Offs . If the Company distributes or dividends shares of Capital Stock of any class or series, or similar equity interest, of or relating to an Affiliate, a Subsidiary or other business unit of the Company to all or substantially all holders of the Common Stock, and such Capital Stock or equity interest is listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “ Spin-Off ”), then the Conversion Rate will be increased based on the following formula:

The adjustment to the Conversion Rate pursuant to this Section 5.05(A)(iii)(2) will be calculated as of the Close of Business on the last Trading Day of the Spin-Off Valuation Period but will be given effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off, with retroactive effect. If a Note is converted and the Conversion Date (in the case of Physical Settlement) or any VWAP Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the Spin-Off Valuation Period, then, notwithstanding anything to the contrary in this Indenture or the Notes, the Company will, if necessary, delay the settlement of such conversion until the third (3rd) (or, if the T+2 Effective Date has occurred by the last day of the Spin-Off Valuation Period, the second (2nd)) Business Day after the last day of the Spin-Off Valuation Period.

- 89 -

To the extent any dividend or distribution of the type set forth in this Section 5.05(A)(iii)(2) is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid.

(iv)     Cash Dividends or Distributions . If any cash dividend or distribution is made to all or substantially all holders of Common Stock, then the Conversion Rate will be increased based on the following formula:

provided , however , that if D is equal to or greater than SP , then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution, at the same time and on the same terms as holders of Common Stock, the amount of cash that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

To the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid.

(v)     Tender Offers or Exchange Offers . If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock, and the value (determined as of the Expiration Time by the Board of Directors) of the cash and other consideration paid per share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale Price per share of Common Stock on the Trading Day immediately after the last date (the “ Expiration Date ”) on

- 90 -

which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased based on the following formula:

provided , however , that the Conversion Rate will in no event be adjusted down pursuant to this Section 5.05(A)(v) , except to the extent provided in the immediately following paragraph. The adjustment to the Conversion Rate pursuant to this Section 5.05(A)(v) will be calculated as of the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period but will be given effect immediately after the Expiration Time, with retroactive effect. If a Note is converted and the Conversion Date (in the case of Physical Settlement) or any VWAP Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the Tender/Exchange Offer Valuation Period, then, notwithstanding anything to the contrary in this Indenture or the Notes, the Company will, if necessary, delay the settlement of such conversion until the third (3rd) (or, if the T+2 Effective Date has occurred by the last day of the Tender/Exchange Offer Valuation Period, the second (2nd)) Business Day after the last day of the Tender/Exchange Offer Valuation Period.

- 91 -

To the extent such tender or exchange offer is announced but not consummated (including as a result of the Company being precluded from consummating such tender or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer are rescinded, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender or exchange offer.

(B)     No Adjustments in Certain Cases .

(i)     Where Holders Participate in the Transaction or Event Without Conversion . Notwithstanding anything to the contrary in Section 5.05(A) , the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring an adjustment pursuant to Section 5.05(A) (other than a stock split or combination of the type set forth in Section 5.05(A)(i) or a tender or exchange offer of the type set forth in Section 5.05(A)(v) ) if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder of Notes, in such transaction or event without having to convert such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the related record date, effective date or Expiration Date, as applicable; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such date.

(C)     Adjustments Not Yet Effective. Notwithstanding anything to the contrary in this Indenture or the Notes, if:

(i)    a Note is to be converted;

(ii)    the record date, effective date or Expiration Time for any event that requires an adjustment to the Conversion Rate pursuant to any of clauses (i)  through (v) , inclusive, of Section 5.05(A) has occurred on or before the Conversion Date for such conversion (in the case of Physical Settlement) or on or before any VWAP Trading Day in the Observation Period for such conversion (in the case of Combination Settlement), but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date or VWAP Trading Day, as applicable;

(iii)    the Conversion Consideration due upon such conversion (in the case of Physical Settlement) or due in respect of such VWAP Trading Day (in the case of Combination Settlement) includes any whole shares of Common Stock; and

(iv)    such shares are not entitled to participate in such event (because they were not held on the related record date or otherwise),

then, solely for purposes of such conversion, the Company will, without duplication, give effect to such adjustment on such Conversion Date (in the case of Physical Settlement) or such VWAP Trading Day (in the case of Combination Settlement). In such case, if the date on which the Company is otherwise required to deliver the consideration due upon such conversion is before

- 92 -

the first date on which the amount of such adjustment can be determined, then the Company will (x) deliver, on such date the Company is otherwise required by this Indenture, the Conversion Consideration due upon such conversion based on the applicable unadjusted Conversion Rate(s); and (y) deliver, on the Business Day immediately after such first date, any additional Conversion Consideration arising from giving effect to such adjustment to the applicable Conversion Rate(s).

(D)     Conversion Rate Adjustments where Converting Holders Participate in the Relevant Transaction or Event. Notwithstanding anything to the contrary in this Indenture or the Notes, if:

(i)    a Conversion Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to any of clauses (i)  through (v) , inclusive, of Section 5.05(A) ;

(ii)    a Note is to be converted pursuant to Physical Settlement or Combination Settlement;

(iii)    the Conversion Date for such conversion (in the case of Physical Settlement) or any VWAP Trading Day in the Observation Period for such conversion (in the case of Combination Settlement) occurs on or after such Ex-Dividend Date and on or before the related record date;

(iv)    the Conversion Consideration due upon such conversion (in the case of Physical Settlement) or due with respect to such VWAP Trading Day (in the case of Combination Settlement) includes any whole shares of Common Stock based on a Conversion Rate that is adjusted for such dividend or distribution; and

(v)    such shares would be entitled to participate in such dividend or distribution (including pursuant to Section 5.02(C) ),

then (x) such Conversion Rate adjustment will not be given effect for such conversion (in the case of Physical Settlement) or for such VWAP Trading Day (in the case of Combination Settlement); and (y) the shares of Common Stock, if any, issuable upon such conversion (in the case of Physical Settlement) or issuable with respect to such VWAP Trading Day (in the case of Combination Settlement) based on such unadjusted Conversion Rate will be entitled to participate in such dividend or distribution.

(E)     Stockholder Rights Plans . If any shares of Common Stock are to be issued upon conversion of any Note and, at the time of such conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under this Indenture upon such conversion, the rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such time, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section 5.05(A)(iii)(1) on account of such separation as if, at the time of such separation, the Company had made a distribution of the type referred to in such Section to all holders of the Common Stock, subject to readjustment in accordance with such Section if such rights expire, terminate or are redeemed.

- 93 -

(F)     Limitation on Effecting Transactions Resulting in Certain Adjustments . The Company will not engage in or be a party to any transaction or event that would require the Conversion Rate to be adjusted pursuant to Section 5.05(A) or Section  5.07 to an amount that would result in the Conversion Price per share of Common Stock being less than the par value per share of Common Stock.

(G)     Equitable Adjustments to Last Reported Sale Price . Whenever any provision of this Indenture requires the Company to calculate the average of the Last Reported Sale Prices, or any function thereof, over a span of multiple days (including to calculate the Stock Price or an adjustment to the Conversion Rate), the Company will make proportionate adjustments, if any, to such calculations to account for any adjustment to the Conversion Rate pursuant to Section 5.05(A)(i) that becomes effective, or any event requiring such an adjustment to the Conversion Rate where the Ex-Dividend Date or effective date, as applicable, of such event occurs, at any time during the period over which such average is to be calculated.

(H)     Calculation of Number of Outstanding Shares of Common Stock . For purposes of Section 5.05(A) , the number of shares of Common Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock; and (ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company pays any dividend or makes any distribution on shares of Common Stock held in its treasury).

(I)     Calculations . All calculations with respect to the Conversion Rate and adjustments thereto will be made to the nearest cent (with 0.5 of a cent rounded upward) or to the nearest 1/10,000th of a share of Common Stock (with 5/100,000ths rounded upward), as applicable.

(J)     Notice of Conversion Rate Adjustments . Upon the effectiveness of any adjustment to the Conversion Rate pursuant to Section 5.05(A) , the Company will promptly send notice to the Holders, the Trustee and the Conversion Agent containing (i) a brief description of the transaction or other event on account of which such adjustment was made; (ii) the Conversion Rate in effect immediately after such adjustment; and (iii) the effective time of such adjustment.

Section 5.06.    V OLUNTARY A DJUSTMENTS .

(A)     Generally . To the extent permitted by law and applicable stock exchange rules, the Company, from time to time, may (but is not required to) increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is either (x) in the best interest of the Company; or (y) advisable to avoid or diminish any income tax imposed on holders of Common Stock or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common Stock or any similar event; (ii) such increase is in effect for a period of at least twenty (20) Business Days; and (iii) such increase is irrevocable during such period.

(B)     Notice of Voluntary Increases . If the Board of Directors determines to increase the Conversion Rate pursuant to this Section  5.06 , then, at least fifteen (15) Business Days

- 94 -

before such increase, the Company will send notice to each Holder, the Trustee and the Conversion Agent of such increase, the amount thereof and the period during which such increase will be in effect.

Section 5.07.    A DJUSTMENTS TO THE C ONVERSION R ATE IN C ONNECTION WITH A M AKE -W HOLE F UNDAMENTAL C HANGE .

(A)     Generally . If a Make-Whole Fundamental Change occurs and the Conversion Date for the conversion of a Note occurs during the related Make-Whole Fundamental Change Conversion Period, then, subject to this Section  5.07 , the Conversion Rate applicable to such conversion will be increased by a number of shares (the “ Additional Shares ”) set forth in the table below corresponding (after interpolation as provided in, and subject to, the provisions below) to the Make-Whole Fundamental Change Effective Date and the Stock Price of such Make-Whole Fundamental Change:

If such Make-Whole Fundamental Change Effective Date or Stock Price are not set forth in the table above, then:

(i)    if such Stock Price is between two Stock Prices in the table above or the Make-Whole Fundamental Change Effective Date is between two Make-Whole Fundamental Change Effective Dates in the table above, then the number of Additional Shares will be determined by a straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices in the table and the earlier and later Make-Whole Fundamental Change Effective Dates in the table above, as applicable, based on a 365- or 366-day year, as applicable; and

(ii)    if the Stock Price is greater than $5.50 (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above are adjusted pursuant to Section 5.07(B) ), or less than $1.70 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the Conversion Rate.

Notwithstanding anything to the contrary in this Indenture or the Notes, in no event will the Conversion Rate be increased to an amount that exceeds 588.1660 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is required to be adjusted pursuant to clauses (i)  through (v) , inclusive, of Section 5.05(A) .

(B)     Adjustment of Stock Prices and Additional Shares . The Stock Prices in the first row ( i.e. , the column headers) of the table set forth in Section 5.07(A) will be adjusted in the

- 95 -

same manner as, and at the same time and for the same events for which, the Conversion Price is adjusted as a result of the operation of clauses (i)  through (v) , inclusive, of Section 5.05(A) . The numbers of Additional Shares in the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Rate is adjusted pursuant to Section 5.07(A) .

(C)     Notice of the Occurrence of a Make-Whole Fundamental Change . If a Make-Whole Fundamental Change occurs, then, promptly and in no event later than the Business Day immediately after the Make-Whole Fundamental Change Effective Date of such Make-Whole Fundamental Change, the Company will notify the Holders, the Trustee and the Conversion Agent of the occurrence of such Make-Whole Fundamental Change and of such Make-Whole Fundamental Change Effective Date, briefly stating the circumstances under which the Conversion Rate will be increased pursuant to this Section  5.07 in connection with such Make-Whole Fundamental Change.

(D)     Settlement of Cash Make-Whole Fundamental Changes . For the avoidance of doubt, if holders of Common Stock receive solely cash in a Make-Whole Fundamental Change, then, pursuant to Section  5.08 , conversions of Notes will thereafter be settled no later than the third (3rd) Business Day after the relevant Conversion Date.

Section 5.08.    E FFECT OF C OMMON S TOCK C HANGE E VENT .

(A)     Generally . If there occurs any:

(i)    recapitalization, reclassification or change of the Common Stock (other than (x) changes solely resulting from a subdivision or combination of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value and (z) stock splits and stock combinations that do not involve the issuance of any other series or class of securities);

(ii)    consolidation, merger, combination or binding share exchange involving the Company;

(iii)    sale, lease or other transfer of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any Person; or

(iv)    other event,

and, as a result which, the Common Stock is converted into, or is exchanged for, or represents solely the right to receive, other securities, cash or other Property, or any combination of the foregoing (such an event, a “ Common Stock Change Event ,” and such other securities, cash or Property, the “ Reference Property ,” and the amount and kind of Reference Property that a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect to any arrangement not to issue or deliver a fractional portion of any security or other Property), a “ Reference Property Unit ”), then, notwithstanding anything to the contrary in this Indenture or the Notes,

- 96 -

(1)    at the effective time of such Common Stock Change Event, (I) the Conversion Consideration due upon conversion of any Note will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 5 (or in any related definitions) were instead a reference to the same number of Reference Property Units; and (II) for purposes of the definition of “Fundamental Change” and “Make-Whole Fundamental Change,” the term “Common Stock” will be deemed to mean the common equity, if any, forming part of such Reference Property;

(2)    if such Reference Property Unit consists entirely of cash, then the Company will be deemed to elect Cash Settlement in respect of all conversions whose Conversion Date occurs on or after the effective date of such Common Stock Change Event and will pay the cash due upon such conversions no later than the third (3rd) (or, if the T+2 Effective Date has occurred by the relevant Conversion Date, the second (2nd)) Business Day after such Conversion Date; and

(3)    for these purposes, the Daily VWAP or Last Reported Sale Price of any Reference Property Unit or portion thereof that does not consist of a class of securities will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof).

If the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of stockholder election, then the composition of the Reference Property Unit will be deemed to be (x) the weighted average, per share of Common Stock, of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election; or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received, per share of Common Stock, by the holders of Common Stock. The Company will notify Holders, the Trustee and the Conversion Agent of the weighted average as soon as practicable after such determination is made.

At or before the effective date of such Common Stock Change Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the “ Successor Person ”) will execute and deliver to the Trustee a supplemental indenture pursuant to Section 8.01(F) , which supplemental indenture will (x) provide for subsequent conversions of Notes in the manner set forth in this Section  5.08 ; (y) provide for subsequent adjustments to the Conversion Rate pursuant to Section 5.07(A) in a manner consistent with this Section  5.08 ; and (z) contain such other provisions as the Company reasonably determines are appropriate to preserve the economic interests of the Holders and to give effect to the provisions of this Section 5.08(A) . If the Reference Property includes shares of stock or other securities or assets of a Person other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain such additional provisions the Company reasonably determines are appropriate to preserve the economic interests of the Holders.

(B)     Notice of Common Stock Change Events . As soon as practicable after learning the anticipated or actual effective date of any Common Stock Change Event, the Company will

- 97 -

notify the Holders, the Trustee and the Conversion Agent of such Common Stock Change Event, including a brief description of such Common Stock Change Event, its anticipated effective date and a brief description of the anticipated change in the conversion right of the Notes.

(C)     Compliance Covenant . The Company will not become a party to any Common Stock Change Event unless its terms are consistent with this Section  5.08 .

Section 5.09.    I NAPPLICABILITY OF C ERTAIN C OVENANTS TO THE C ONVERSION OF THE N OTES .

Notwithstanding anything to the contrary in this Indenture or the Notes, neither Section  3.11 nor 3.15 will prohibit or otherwise restrict the conversion of any Note in accordance with the terms of this Indenture (including the transfer of any assets from any Subsidiary of the Company to the Company solely for purposes of delivering any Conversion Consideration upon conversion of any Note).

Section 5.10.    R ESPONSIBILITY OF T RUSTEE AND C ONVERSION A GENT .

Neither the Trustee nor any Conversion Agent (A) will at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment to (including any increase in) the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or provided in this Indenture or any supplemental indenture to be employed, in making the same; (B) will be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; (C) makes any representations with respect to the foregoing; or (D) will be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 5 . Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent will be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section  5.08 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in Section  5.08 or to any adjustment to be made with respect thereto, but may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and will be protected in conclusively relying upon, the Officer’s Certificate (which the Company will file with the Trustee prior to the execution of any such supplemental indenture in addition to any other deliverables required under this Indenture in connection with the execution of such supplemental indenture) with respect thereto.

Upon the failure of any payment when due of any amount so guaranteed, and upon the failure of any performance so guaranteed, for whatever reason, the Guarantors will be jointly and severally obligated to pay or perform, as applicable, the same immediately.
