WARRANT

Certificate No.: W - 2		Date: July 29, 2004

          FOR CONSIDERATION RECEIVED, Occum Acquisition Corp., a Delaware corporation (the “Company”), hereby grants to Berkshire Hathaway Inc. (the “Warrant Holder”) this warrant certificate (this “Warrant”) to purchase, in accordance with the terms set forth herein, 1,090,560 shares (the “Warrant Shares”) of the Company’s common shares, initially having a par value of U.S. $0.01 per share (the “Common Shares”), at a price per share equal to U.S. $100, as adjusted from time to time

pursuant to Section 2 hereof (the “Exercise Price”) but at no time shall the Exercise Price be less than the then current par value of any share to be issued pursuant hereto.

          This Warrant is issued pursuant to a letter agreement, dated as of March 8, 2004, between the Company and the Warrant Holder.

          This Warrant is subject to the following provisions:

          SECTION 1. Warrant Terms. (a) This Warrant is for the purchase of the Warrant Shares at the Exercise Price.

          (b) This Warrant shall expire on the tenth anniversary of the date hereof (the “Expiration Date”). The Warrant exercise procedure set forth in Section 3 hereof must be commenced by the Warrant Holder by 3:30 p.m. New York City time on such Expiration Date.

          SECTION 2. Anti-dilution Provisions. In order to prevent dilution of the purchase rights granted under Section 1 hereof, the Exercise Price shall be subject to adjustment from time to time pursuant to this Section 2; provided, however, that under no circumstances will the Exercise Price be less than the then current par value of any share to be issued under this Warrant.

          (a) Effect on Exercise Price of Certain Events. For purposes of determining the adjusted Exercise Price, the following shall be applicable:

     (1) Share Dividend, Subdivision or Consolidation/Combination of Common Shares. If the Company, at any time while this Warrant is outstanding, (A) shall pay a stock or bonus share dividend on its Common Shares or pay any other distribution in Common Shares, (B) subdivide the class of Common Shares into a larger number of shares or (C) consolidate/combine the class of Common Shares into a smaller number of shares, then the Exercise Price thereafter shall be determined by multiplying the Exercise Price by a fraction (x) the numerator of which shall be the number of Common Shares (excluding treasury shares, if any) issued and outstanding before such event and (y) the denominator of which shall be the number of Common Shares (excluding treasury shares, if any) issued and outstanding after such event. Any adjustment made pursuant to this Section 2(a)(1) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination.

     (2) Issuance of Additional Common Shares. In case the Company at any time or from time to time after the date hereof shall issue or sell additional Common Shares, other than any issuance to which Section 2(a)(1) shall apply, without consideration or for a consideration per share less than the Fair Market Value of the Common Shares on the day immediately prior to such issue or sale, then, and in each such case, subject to Section 2(b)(iv), the Exercise Price shall be

reduced, concurrently with such issue or sale, to a price determined by multiplying such Exercise Price by a fraction

     (x) the numerator of which shall be (i) the number of Common Shares outstanding immediately prior to such issue or sale plus (ii) the number of Common Shares which the aggregate consideration received by the Company for the total number of such additional Common Shares so issued or sold would purchase at such Fair Market Value of the Common Shares, and

     (y) the denominator of which shall be the number of Common Shares outstanding immediately after such issue or sale;

provided that for the purposes of this Section 2(a)(2), treasury shares shall not be deemed to be outstanding.

     (3) Dividends and Distributions. In case the Company at any time or from time to time after the date hereof shall declare, order, pay or make a dividend or other distribution (including any distribution of other or additional stock or other securities or property or options, warrants or other rights to purchase Common Shares or Convertible Securities (as hereinafter defined) (other than options granted to employees of the Company) (collectively, “Assets”) by way of dividend or spin-off, reclassification, recapitalization or similar corporate rearrangement) on the Common Shares, other than a dividend payable in additional Common Shares (which is the subject of Section 2(a)(1) hereof), then, and in each such case, the Company shall make the same dividend or distribution to Warrant Holders as it makes to holders of Common Shares pro rata based on the number of Common Shares for which such Warrants are then exercisable, and the Exercise Price shall not be adjusted in respect thereof.

     (4) Consolidation, Merger, etc.

     (A) Adjustments for Consolidation, Merger, Sale of Assets, Reorganization, etc. In case the Company after the date hereof (i) shall consolidate with or merge into any other Person (as hereinafter defined) and shall not be the continuing or surviving corporation of such consolidation or merger, (ii) shall permit any other Person to consolidate with or merge into the Company and the Company shall be the continuing or surviving Person but, in connection with such consolidation or merger, the Common Shares shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property, (iii) shall transfer all or substantially all of its properties or assets to any other Person, (iv) shall effect a capital reorganization or reclassification of the Common Shares (other than a capital reorganization or reclassification resulting in an adjustment to the Exercise Price as provided in another paragraph of this Section 2), or (v) shall effect any other transaction in which the Common Shares are

changed into or exchanged for stock or other securities of any other Person, then, except and insofar as otherwise provided in Section 2(a)(4)(C) in the case of each such transaction, proper provision shall be made so that, upon the basis and the terms and in the manner provided in this Warrant, the holder of this Warrant, upon the exercise hereof at any time after the consummation of such transaction, shall be entitled to receive (at the aggregate Exercise Price in effect at the time of such consummation for all Common Shares issuable upon such exercise immediately prior to such consummation), in lieu of the Common Shares issuable upon such exercise prior to such consummation, the amount of securities, cash or other property to which such holder would actually have been entitled as a shareholder upon such consummation if such holder had exercised the rights represented by this Warrant immediately prior thereto. As used herein, “Person” shall mean an individual, company, corporation, limited liability company, firm, partnership, trust, estate, unincorporated association or other entity.

     (B) Assumption of Obligations. Notwithstanding anything contained in this Warrant or in the Shareholders Agreement to the contrary, the Company will not effect any of the transactions described in Sections 2(a)(4)(A)(i)-(v) unless, prior to the consummation thereof, each Person (other than the Company) which may be required to deliver any stock, securities, cash or property upon the exercise of this Warrant as provided herein shall assume, by written instrument delivered to, and reasonably satisfactory to, the holder of this Warrant, the obligations of the Company under this Warrant (and if the Company shall survive the consummation of such transaction, such assumption shall be in addition to, and shall not release the Company from, any continuing obligations of the Company under this Warrant). Nothing in this Section 2(a)(4) shall be deemed to authorize the Company to enter into any transaction not otherwise permitted by the Shareholders Agreement or the By-laws.

     (C) Qualifying Transactions. (1) In the event that, after the date hereof, the Company shall effect a transaction of the type contemplated by subparagraph (A) above and in connection therewith (x) the Common Shares are exchanged in whole or in part for cash (other than cash in lieu of fractional shares), securities (other than Voting Common Stock (as defined below)) or other property (collectively, “Non-Common Consideration”) and (y) the Per Share Value (as defined below) exceeds the Subscription Price (as defined below) (any such transaction being referred to herein as a “Qualifying Transaction”), then (i) the holder of this Warrant shall receive, upon the consummation of the Qualifying Transaction, an amount in cash equal to the Intrinsic Value Amount (as defined below) and (ii) if any portion of the consideration to be received by holders of Common Shares in such Qualifying Transaction consists of Voting Common Stock (as defined below), the holder of the Warrant, upon the exercise hereof at any time after the consummation of such

Qualifying Transaction, shall be entitled to receive, at the aggregate exercise price determined pursuant to subparagraph (C)(3) below, the number of shares of Voting Common Stock determined pursuant to subparagraph (C)(3) below.

     (2) Certain Definitions. For purposes of this Section 2(a)(4), the following terms have the following meanings:

          “Per Share Value” means the average value of the consideration to be received in respect of each outstanding Common Share pursuant to the Qualifying Transaction as determined by mutual agreement of the Independent Directors (as defined in Section 2(b)(ii) below) and the holders of not less than 50% in interest of all outstanding warrants to purchase Common Shares containing this provision, or, if they shall fail to agree, by an Investment Bank.

          “Subscription Price” means U.S. $100.00; provided, however, that such amount shall be (i) adjusted in an appropriate and proportionate manner consistent with the provisions for adjusting the Exercise Price in Section 2(a)(1) for any events that require an adjustment in the Exercise Price pursuant to such section and (ii) reduced by an amount equal to the pre-tax value (determined pursuant to Section 2(b)(i)) per Common Share of any dividend or other distribution described in Section 2(a)(3).

          “Voting Common Stock” means, as to any issuer, (i) voting equity securities of such issuer having no preference as to dividends or in a liquidation over any other securities of such issuer, (ii) nonvoting equity securities of such issuer which are in all other respects identical to, and are expected to have, after completion of the Qualifying Transaction, liquidity substantially equivalent to or greater than, the outstanding voting equity securities of such issuer that would fit the description in the preceding clause (i), or (iii) securities convertible into or exchangeable for the voting or nonvoting securities described in clause (i) or (ii).

          “Intrinsic Value Amount” means (i) the Applicable Black-Scholes Value minus (ii) the Applicable Reduction, if any.

          “Applicable Black-Scholes Value” shall mean the product of (i) the Black-Scholes Value and (ii) the Non-Common Stock Portion.

          “Non-Common Stock Portion” means (i) one minus (ii) the Common Stock Portion.

          “Common Stock Portion” means the quotient obtained by dividing (i) the total value of the shares of Voting Common Stock to be issued in respect of the outstanding Common Shares pursuant to the Qualifying Transaction by (ii) the total value of the shares of Voting Common Stock and Non-Common Consideration to be issued in respect of the outstanding Common Shares pursuant to the Qualifying Transaction, in each case as determined by mutual agreement of the Independent Directors and the holders of not less than 50% in interest of all outstanding warrants to purchase Common Shares containing this provision, or, if they shall fail to agree, by an Investment Bank.

          “Applicable Reduction” means the product of (i) the Reduction Amount and (ii) the Non-Common Stock Portion.

          “Reduction Amount” means the product of (i) the Discount Factor and (ii) the amount by which (x) the Black-Scholes Value exceeds (y) the Total Spread.

          “Discount Factor” means (A) one minus (B) the quotient obtained by dividing (i) the amount by which (x) the Per Share Value exceeds (y) the Subscription Price by (ii) the amount by which (x) the Hurdle Price exceeds (y) the Subscription Price; provided, that if the quotient determined pursuant to clause (B) is greater than one, such quotient shall be deemed to be one.

          “Total Spread” means the product of (i) the total number of Warrant Shares purchasable pursuant to this Warrant immediately prior to the completion of the Qualifying Transaction and (ii) the Spread.

          “Spread” means the amount by which (i) the Per Share Value exceeds (ii) the Subscription Price; provided, however, that in the event the Subscription Price exceeds the Per Share Value, the Spread shall be deemed to be zero.

          “Hurdle Price” means U.S. $155.00; provided, however, that such amount shall be (i) adjusted in an appropriate and proportionate manner consistent with the provisions for adjusting the Exercise Price in Section 2(a)(1) for any events that require an adjustment in the Exercise Price pursuant to such section and (ii) reduced by an amount equal to the pre-tax value (determined pursuant to Section 2(b)(i)) per Common Share of any dividend or other distribution described in Section 2(a)(3).

          “Investment Bank” means an independent nationally-recognized U.S. investment banking firm selected by the Independent Directors with the consent of the holders of not less than 50% in interest of all outstanding warrants to purchase Common Shares containing this provision (which consent shall not be unreasonably withheld), the fees and expenses of which shall be shared equally by the Company on the one hand and such holders on the other.

          “Black-Scholes Value” means the value of this Warrant immediately prior to consummation of the Qualifying Transaction, as calculated by an Investment Bank, using the Black-Scholes calculation method for valuing options and the following assumptions:

Volatility =		25%
Risk Free Rate =		the then current effective U.S. Federal government interest rate for a bond or note with a remaining time to maturity equal to the Term of the Warrant then in effect
Dividend Yield =		0%

Exercise Price =		the Exercise Price in effect immediately prior to the consummation of the Qualifying Transaction
Term of the Warrant =		the lesser of five years and the remaining term of the Warrant, measured from the date of completion of the Qualifying Transaction to the Expiration Date

The underlying security price for purposes of the Black-Scholes calculation shall be the Per Share Value.

          Exhibit C to this Warrant contains examples illustrating certain of the calculations required by this Section 2(a)(4)(C).

     (3) Voting Common Stock Consideration. In the event of a Qualifying Transaction in which any portion of the consideration to be received by holders of Common Shares in such Qualifying Transaction consists of Voting Common Stock, then proper provision shall be made so that, upon the basis and the terms and in the manner provided in this Warrant, the holder of this Warrant, upon the exercise hereof at any time after the consummation of such Qualifying Transaction, shall be entitled to receive (at the aggregate exercise price determined pursuant to this subparagraph (3)) a number of shares of Voting Common Stock equal to the product of (i) the product of (x) the aggregate number of Warrant Shares purchasable pursuant to this Warrant immediately prior to the completion of the Qualifying Transaction and (y) the Common Stock Portion and (ii) the Calculated Exchange Ratio. The aggregate exercise price of this Warrant after the consummation of such Qualifying Transaction shall be equal to the product of (i) the aggregate Exercise Price of this Warrant for the number of Warrant Shares purchasable pursuant to this Warrant immediately prior to the completion of the Qualifying Transaction and (ii) the Common Stock Portion.

For purposes of this subparagraph (3):

          “Calculated Exchange Ratio” means the quotient obtained by dividing (i) the Per Share Value by (ii) the Average Closing Price of the Voting Common Stock.

          “Average Closing Price” means (a) the average of the closing prices per share of the Voting Common Stock on the national securities exchange or automated quotation system on which such stock is then listed for the 10 consecutive trading days immediately preceding the closing date of the Qualifying Transaction, or (b) if such Voting Common Stock is not so listed, the fair market value per share of such Voting Common Stock, determined by mutual agreement of the Independent Directors and the holders of not less than 50% in interest of all outstanding warrants to purchase Common Shares containing this provision, or, if they shall fail to agree, by an Investment Bank.

     (4) Cancelation of Warrant. In the event of a Qualifying Transaction in which the Common Stock Portion is zero, then the holder of this Warrant shall surrender this Warrant at the time of payment of the Intrinsic Value Amount,

whereupon this Warrant shall be canceled and all rights hereunder shall expire. In the event of a Qualifying Transaction in which the Common Stock Portion is more than zero, then the holder of this Warrant shall surrender this Warrant at the time of payment of the Intrinsic Value Amount in exchange for a warrant of like tenor representing the right to purchase the number of shares of Voting Common Stock determined pursuant to Section 2(a)(4)(C)(3) at the aggregate exercise price as determined pursuant to Section 2(a)(4)(C)(3).

     (5) Cash Elections; etc. In the event that the type of consideration to be received per Common Share in a Qualifying Transaction is subject to the election of the holders thereof, such election permits such holder to elect to receive Voting Common Stock and there is no limitation on the number of shares of Voting Common Stock to be issued in the Qualifying Transaction, then (i) after the consummation of such transaction this Warrant shall be exercisable solely for Voting Common Stock, (ii) such transaction shall not be deemed to constitute a Qualifying Transaction and (iii) the provisions of Section 2(a)(4)(A) shall apply.

     (6) All Reasonable Efforts. In the case of a Qualifying Transaction in which any portion of the consideration to be received by the holders of Common Shares consists of Voting Common Stock, the holder of this Warrant and the Company shall use all reasonable efforts to cause this Warrant to become exercisable solely for Voting Common Stock and, if the Person who shall be issuing Voting Common Stock in such transaction agrees in writing that this Warrant shall be exercisable solely for Voting Common Stock, then (i) such transaction shall not be deemed to constitute a Qualifying Transaction and (ii) the provisions of Section 2(a)(4)(A) shall apply.

          (b) Other Provisions Applicable to Adjustments Under This Section. The following provisions shall be applicable to the making of adjustments to the number of Warrant Shares for which the Warrant is exercisable provided for in this Section 2.

     (i) Adjustment in Number of Warrant Shares. Upon each adjustment of the Exercise Price pursuant to Sections 2(a)(1) or 2(a)(2), the number of Common Shares for which this Warrant is exercisable shall be adjusted by multiplying the number of Common Shares for which this Warrant was exercisable prior to such adjustment by a fraction (i) whose numerator is the Exercise Price in effect immediately prior to such adjustment and (ii) whose denominator is the Exercise Price in effect immediately after such adjustment.

     (ii) Computation of Asset Value and Fair Market Value for Purposes of Section 2. To the extent that the Company shall distribute Assets other than cash, except as herein otherwise expressly provided, then the value of such Assets shall be determined by mutual agreement of the Independent Directors and the holders of not less than 50% in interest of all outstanding warrants to purchase Common Shares containing this provision, or, if they shall fail to agree, by an Investment Bank. The “Fair Market Value” of the Common Shares at any given time shall mean (a) if the Common Shares are listed on a

securities exchange (or quoted in a securities quotation system), the average closing sale price of the Common Shares on such exchange (or in such quotation system), or, if the Common Shares are listed on (or quoted in) more than one exchange (or quotation system), the average closing sale price of the Common Shares on the principal securities exchange (or quotation system) on which the Common Shares are then traded, or, if the Common Shares are not then listed on a securities exchange (or quotation system) but are traded in the over-the-counter market, the average of the latest bid and asked quotations for the Common Shares in such market, in each case for the last five trading days immediately preceding the day on which such Fair Market Value is determined in accordance with the applicable provision of this Section 2 or (b) if no such closing sales prices or quotations are available because such shares are not publicly traded or otherwise, the fair value of such shares as determined by mutual agreement of the Independent Directors and the holders of not less than 50% in interest of all outstanding warrants to purchase Common Shares containing this provision, or, if they shall fail to agree, by an Investment Bank. As used herein, the term “Independent Director” shall mean each member of the Board of Directors of the Company that is not (x) a director, officer or employee of any Warrant Holder or any affiliate of any Warrant Holder, (y) the holder of a 10% or greater equity interest in any Warrant Holder or any affiliate of any Warrant Holder or (z) a member of the immediate family of any director, officer or employee of any Warrant Holder or any holder of a 10% or greater equity interest in any such Warrant Holder or any affiliate of any Warrant Holder.

     (iii) When Adjustment To Be Made. The adjustments required by this Section 2 shall be made whenever and as often as any specified event requiring an adjustment shall occur. For the purpose of any adjustment, any specified event shall be deemed to have occurred at the close of business on the date of its occurrence.

     (iv) Fractional Interest: Rounding. In computing adjustments under this Section 2, fractional interests in Common Shares shall be taken into account to the nearest 1/l0th of a share, and adjustments in the Exercise Price shall be made to the nearest $.001.

     (v) Certain Exclusions. No adjustment in the number of Common Shares purchasable under this Warrant or the Exercise Price therefor shall be made as a result of (x) any adjustment in the number of Common Shares purchasable under any other Warrant or the exercise price thereunder, or (y) for the issuance of any employee stock options or any Common Shares issuable under employee stock options, employee stock purchase plans, or any other form of equity based compensation granted to employees of the Company.

     (vi) Computation of Consideration. For the purposes of this Section 2,

     (A) the consideration for the issue or sale of any additional Common Shares shall, irrespective of the accounting treatment of such consideration,

     (x) insofar as it consists of cash, be computed at the net amount of cash received by the Company,

     (y) insofar as it consists of property (including securities) other than cash, be computed at the fair value thereof at the time of such issue or sale, as determined by mutual agreement of the Independent Directors and the holders of not less than 50% in interest of all outstanding warrants to purchase Common Shares containing adjustment provisions of like tenor to the applicable adjustment provision contained in this Warrant, or, if they shall fail to agree, by an Investment Bank, and

     (z) in case additional Common Shares are issued or sold together with other stock or securities or other assets of the Company for a consideration which covers both, be the portion of such consideration so received, computed as provided in clauses (x) and (y) above, allocable to such additional Common Shares, all as determined in good faith by mutual agreement of the Independent Directors and the holders of not less than 50% in interest of all outstanding warrants to purchase Common Shares containing adjustment provisions of like tenor to the applicable adjustment provision contained in this Warrant, or, if they shall fail to agree, by an Investment Bank;

     (B) additional Common Shares deemed, pursuant to Section 2(c), to have been issued, relating to Options and Convertible Securities, shall be deemed to have been issued for a consideration per share determined by dividing

     (x) the total amount, if any, received and receivable by the Company as consideration for the issue, sale, grant or assumption of the Options or Convertible Securities in question, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration to protect against dilution) payable to the Company upon the exercise in full of such Options or the conversion or exchange of such Convertible Securities or, in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, in each case computing such consideration as provided in the foregoing subdivision (A),

by

     (y) the maximum number of Common Shares (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities; and

     (C) additional Common Shares deemed to have been issued pursuant to Section 2(a)(1), relating to stock dividends, stock splits, etc., shall be deemed to have been issued for no consideration.

          (c) Treatment of Options and Convertible Securities. In case the Company at any time or from time to time after the date hereof shall issue, sell, grant or assume, or shall fix a record date for the determination of holders of any class of securities of the Company other than the Common Shares entitled to receive, any (x) options, warrants or other rights to purchase Common Shares (other than options granted to employees) or Convertible Securities (as defined below) (“Options”) or (y) securities convertible into or exchangeable for Common Shares (“Convertible Securities”), then, and in each such case, the maximum number of additional Common Shares (as set forth in the instrument relating thereto, without regard to any provisions contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed for purposes of Section 2(a)(2) to be additional Common Shares issued as of the time of such issue, sale, grant or assumption or, in case such a record date shall have been fixed, as of the close of business on such record date (or, if the Common Shares trade on an ex-dividend basis, on the date prior to the commencement of ex-dividend trading); provided, however, that such additional Common Shares shall not be deemed to have been issued unless the consideration per share (determined pursuant to section 2(b)(vi)) would be less than the Fair Market Value on the date immediately prior to such issue, sale, grant or assumption or immediately prior to the close of business on such record date (or, if the Common Shares trade on an ex-dividend basis, on the date prior to the commencement of ex-dividend trading), as the case may be, and provided further that in any such case in which additional Common Shares are deemed to be issued:

     (i) no further adjustment of the Exercise Price shall be made upon the subsequent issue or sale of Convertible Securities or Common Shares upon the exercise of such Options or the conversion or exchange of such Convertible Securities;

     (ii) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase or decrease in the consideration payable to the Company, or decrease or increase in the number of additional Common Shares issuable, upon the exercise, conversion or exchange thereof (by change of rate or otherwise), the Exercise Price computed upon the original issue, sale, grant or assumption thereof (or upon the occurrence of the

record date, or date prior to the commencement of ex-dividend trading, as the case may be, with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such Options, or the rights of conversion or exchange under such Convertible Securities, which are outstanding at such time;

          (iii) upon the expiration (or purchase by the Company and cancellation or retirement) of any such Options which shall not have been exercised or the expiration of any rights of conversion or exchange under any such Convertible Securities which (or purchase by the Company and cancellation or retirement of any such Convertible Securities the rights of conversion or exchange under which) shall not have been exercised, the Exercise Price computed upon the original issue, sale, grant or assumption thereof (or upon the occurrence of the record date, or date prior to the commencement of ex-dividend trading, as the case may be, with respect thereto), and any subsequent adjustments based thereon, shall, upon such expiration (or such cancellation or retirement, as the case may be), be recomputed as if:

     (A) in the case of Options for Common Shares or Convertible Securities, the only additional Common Shares issued or sold were the additional Common Shares, if any, actually issued or sold upon the exercise of such Options or the conversion or exchange of such Convertible Securities and the consideration received therefor was (x) an amount equal to (1) the consideration actually received by the Company for the issue, sale, grant or assumption of all such Options, whether or not exercised, plus (2) the consideration actually received by the Company upon such exercise, minus (3) the consideration paid by the Company for any purchase of such Options which were not exercised, or (y) an amount equal to (1) the consideration actually received by the Company for the issue or sale of all such Convertible Securities which were actually converted or exchanged, plus (2) the additional consideration, if any, actually received by the Company upon such conversion or exchange, minus (3) the consideration paid by the Company for any purchase of such Convertible Securities the rights of conversion or exchange under which were not exercised, and

     (B) in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued or sold upon the exercise of such Options were issued at the time of the issue, sale, grant or assumption of such Options, and the consideration received by the Company for the additional Common Shares deemed to have then been issued was an amount equal to (x) the consideration actually received by the Company for the issue, sale, grant or assumption of all such Options, whether or not exercised, plus (y) the consideration deemed to have been received by the Company (pursuant to section 2(b)(vi)) upon the issue or sale of such Convertible Securities with respect to which such Options

were actually exercised, minus (z) the consideration paid by the Company for any purchase of such Options which were not exercised;

     (iv) no readjustment pursuant to subdivision (ii) or (iii) above shall have the effect of increasing the Exercise Price by an amount in excess of the amount of the adjustment thereof originally made in respect of the issue, sale, grant or assumption of such Options or Convertible Securities; and

     (v) in the case of any such Options which expire by their terms not more than 30 days after the date of issue, sale, grant or assumption thereof, no adjustment of the Exercise Price shall be made until the expiration or exercise of all such Options, whereupon such adjustment shall be made in the manner provided in subdivision (iii) above.

          (d) Other Dilutive Events. In case any event shall occur as to which the provisions of Section 2 are not strictly applicable but the failure to make any adjustment would not fairly protect the purchase rights (including the rights provided under Section 2(a)(4)(C)) represented by this Warrant in accordance with the essential intent and principles of such Sections, then, in each such case, the Independent Directors of the Company shall appoint an Investment Bank, which shall give its opinion upon the adjustment, if any, on a basis consistent with the essential intent and principles established in Section 2, necessary to preserve, without dilution, the purchase rights represented by this Warrant. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the holder of this Warrant and shall make the adjustments described therein.

          (e) Notices. Immediately upon any adjustment of the Exercise Price, the Company shall give, or cause to be given, written notice thereof, executed by the Chief Financial Officer (or, if none, the Chief Executive Officer or President) of the Company, to the Warrant Holder, setting forth in reasonable detail and certifying the event requiring the adjustment, the method by which the adjustment was calculated, the number of Warrant Shares for which the Warrant is exercisable and the Exercise Price after giving effect to such adjustment. The Company shall keep at its registered office copies of all such written notices and cause the same to be available for inspection during normal business hours by the Warrant Holder. The Company shall give, or cause to be given, written notice to the Warrant Holder at least 10 days prior to the date on which the Company closes its books or takes a record (i) with respect to any dividend or distribution upon Common Shares, (ii) with respect to any pro rata subscription offer to holders of Common Shares or (iii) for determining rights to vote with respect to any transaction described in Section 2(a)(4), dissolution or liquidation. The Company shall also give, or cause to be given, written notice to the Warrant Holder at least 10 days prior to the date on which any transaction described in Section 2(a)(4) shall take place.

          SECTION 3. Exercise of Warrant. (a) Exercise Procedure. The Warrant Holder may exercise all or a portion of this Warrant for all or a portion of the Warrant Shares at any time and from time to time commencing after the date hereof until 3:30 p.m. New York City time, on the Expiration Date by irrevocably surrendering at the

registered office of the Company this Warrant and a completed Exercise Agreement (substantially in the form of Exhibit A attached hereto) setting forth the number of Warrant Shares being exercised, and by paying the Exercise Price in one of the following manners:

     (i) Cash Exercise. The Warrant Holder shall deliver to the Company by wire transfer of immediately available funds an amount equal to the Exercise Price per Warrant Share exercised in the Exercise Agreement; or

     (ii) Cashless Exercise. After the date of issuance of this Warrant, if the Common Shares are listed on a national securities exchange, automated quotation system or are available for sale in the over-the-counter market, the Warrant Holder shall have the right to surrender this Warrant to the Company (including that portion of the Warrant in payment of the Exercise Price to effect such cashless exercise) together with a notice of cashless exercise, in which event the Company shall exchange such portion of the Warrant subject to the Exercise Agreement, as the circumstances require in order for such number of Common Shares to be issued, determined as follows:

X = Y multiplied by (A-B)/A where:

X = the number of Common Shares to be issued to the Warrant Holder

Y = the number of Warrant Shares with respect to which this Warrant is being exercised in the Exercise Agreement

A = the average of the per share Market Price of the Common Shares for the five (5) trading days immediately prior to (but not including) the date of exercise (but not less than the then par value of the Common Shares)

B = the Exercise Price

If the foregoing calculation results in a negative number, then no Warrant Shares shall be issued.

For purposes of Rule 144 promulgated under the Securities Act only, it is intended, understood and acknowledged that the Warrant Shares issued in a cashless exercise transaction shall be deemed to have been acquired and the full purchase price therefor paid by the Warrant Holder, and the holding period for the Warrant Shares shall be deemed to have been commenced on the issue date to the extent permitted by Rule 144.

For purposes hereof, “Market Price” means on any particular date (i) the closing bid price per Common Share on such date on the national securities exchange or automated quotation system on which the Common Shares are then listed or if there is no such price on such date, then the closing bid price on such exchange or quotation system on the date nearest preceding such date, or (ii) if the Common Shares are not then listed on a national

securities exchange or automated quotation system, the closing bid price for each Common Share in the over-the-counter market, as reported by the National Quotation Bureau Incorporated (or similar organization or agency succeeding to its functions of reporting prices) at the close of business on such date.

          (b) The Company shall cause certificates for the Warrant Shares to be issued in the name of and delivered to the Warrant Holder, or subject to the transfer restrictions referred to in the legend endorsed hereon, as the Warrant Holder may direct, as soon as practicable and in any event within ten (10) business days after receipt by the Company of the items required by Section 3(a) for the respective method or methods of exercise. Unless this Warrant has expired or all of the purchase rights represented hereby have been exercised, the Company shall prepare a new Warrant, substantially identical hereto, representing the rights formerly represented by this Warrant which have not expired or been exercised and shall, within such 10-business-day period, deliver such new Warrant to such Warrant Holder.

          (c) Any Warrant Shares issuable upon the proper exercise of this Warrant shall be deemed to have been issued to the Warrant Holder on the date the Company receives the completed Exercise Agreement and payment of the Exercise Price, if any, and the Warrant Holder shall be deemed for all purposes to have become the record holder of such Common Shares on such date.

          (d) The issuance of certificates for the Warrant Shares shall be made without charge to the Warrant Holder for any issuance tax in respect thereof or other cost incurred by the Company in connection with such exercise and the related issuance of the Warrant Shares.

          (e) The Company shall at all times reserve and keep available such number of authorized but unissued Common Shares, solely for the purpose of issuance upon exercise of this Warrant, as are issuable upon exercise of this Warrant. All Warrant Shares shall, when issued, be duly and validly issued, fully paid and nonassessable (meaning that no further sums are required to be paid by the holders thereof in connection with the issue thereof) and free from all taxes, liens and charges. The Company shall take such actions as may be necessary to ensure that the Warrant Shares may be so issued without violation of any applicable law or governmental regulation or any requirements of any securities exchange upon which its shares may be listed (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance).

          (f) Without prejudice to the rights of the Warrant Holders as signatory to the Shareholders Agreement as set forth in Section 5 hereof, the Company shall have the option, in its sole discretion, to deliver Warrant Shares which are (i) subject to the securities law transfer restrictions referred to in the legend endorsed hereon or (ii) subject to a registration statement filed under the Securities Act.

          SECTION 4. Warrant Transfer Restrictions. Subject to the transfer conditions referred to in the legend endorsed hereon, this Warrant and all rights

hereunder are transferable, in whole or in part, without charge to the Warrant Holder, upon surrender of this Warrant with a properly executed Assignment (substantially in the form of Exhibit B hereto) at the registered office of the Company; provided, however, that (i) such transfer shall comply with Section 2 of the Shareholders Agreement and (ii) prior to such transfer, the transferee shall enter into the Shareholders Agreement with the Company.

          SECTION 5. Shareholders Agreement; Registration Rights. The Warrant Holder, as signatory to the Shareholders Agreement, shall have the rights set forth in Section 3 of the Shareholders Agreement with respect to this Warrant and any Warrant Shares issued hereunder.

          SECTION 6. Amendment and Waiver. Except as otherwise provided herein, the provisions of this Warrant may be amended only if the Company has obtained the written consent of the Warrant Holder and a majority of the Independent Directors has approved the amendment.

          SECTION 7. Descriptive Headings. The descriptive headings of this Warrant are inserted for convenience only and do not constitute a part of this Warrant.

          SECTION 8. Definitions. Terms used in this Warrant unless otherwise defined herein shall have the meaning ascribed to them in the Shareholders Agreement.

          SECTION 9. Governing Law. This Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of New York. Each party hereby irrevocably submits to the nonexclusive jurisdiction of the courts of New York for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that (i) it is not personally subject to the jurisdiction of any such court, and/or (ii) that such suit, action or proceeding is not brought in the proper forum. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.

          SECTION 10. Complete Agreement; Severability. Except as otherwise expressly set forth herein, this Warrant embodies the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way. In case any provision of this Warrant shall be invalid, illegal or unenforceable, such invalidity, illegality, or unenforceability shall not in any way affect or impair any other provision of this Warrant.

EXHIBIT C

The following two examples illustrate certain of the calculations in Section 2(a)(4)(C) of the Warrant. These examples assume that the Warrant is for 100 shares; the Exercise Price is $100.00 per share; the Subscription Price is $100.00; and the Hurdle Price is $155.00.

Example A

Per Share Value: $140.00
Non-Common Stock Portion: 0.30
Average Closing Price: $47.00
Spread: $40.00
Total Spread: $4,000.00
Black Scholes Value: $4,500.00

Applicable Black-Scholes Value = $4,500.00 x .30 = $1,350.00
Applicable Reduction = Reduction Amount (136.35) x .30 = $40.90
Reduction Amount = Discount Factor (.2727) x $500.00 = $136.35
Discount Factor = (x) One minus (y) .7273 - .2727
Intrinsic Value Amount = $1,309.10
Post-merger Warrant = 208.51 shares at aggregate exercise price of $7,000.00 (in-the-money value = $2,800.00)

Example B

Per Share Value: $300.00
Non-Common Stock Portion: 0.40
Average Closing Price: $97.00
Spread: $200.00
Total Spread: $20,000.00

Black-Scholes Value: $23,000.00

Applicable Black-Scholes Value = $23,000.00 x .40 = $9,200.00
Applicable Reduction = Reduction Amount (0) x.40 = $0
Reduction Amount = Discount Factor (0) x $3,000.00 = $0
Discount Factor = (x) One minus (y) [$200.00/55 = 3.6364 but not more than one] = 0
Intrinsic Value Amount = $9,200.00
Post-merger Warrant = 185.567 shares at aggregate exercise price of $6,000.00 (in-the-money value = $12,000.00)

          IN WITNESS WHEREOF, the Company has caused this Warrant to be signed and attested by its duly authorized officer and to be dated the date of issuance hereof.
