Default Settlement Method:	Net Share Settlement

(y) deleting the phrase “neither the Non-Hedging Party nor the Lending Party lends Shares in the amount of the Hedging Shares or” in the penultimate sentence.

(ii) Announcement Event. If an Announcement Date occurs in respect of a Merger Event or Tender Offer (such occurrence, an “Announcement Event”), then on the earliest to occur of the Expiration Date, the date occurring a commercially reasonable period of time after the relevant Announcement Cessation Date, an Early Termination Date or other date of cancellation (the “Announcement Event Adjustment Date”) in respect of each Warrant, the Calculation Agent will determine the cumulative economic effect on such Warrant of the Announcement Event and the Announcement Cessation Date, if any (without duplication in respect of any other adjustment or cancellation valuation made pursuant to the Equity Definitions, regardless of whether the Announcement Event actually results in a Merger Event or Tender Offer, and taking into account such factors as the Calculation Agent shall determine, including, without limitation, stock price movement, changes in volatility, expected dividends, stock loan rate or liquidity relevant to the Shares or the Transaction whether prior to or after the Announcement Event or for any period of time, including, without limitation, the period from the Announcement Event to the relevant

12

Announcement Event Adjustment Date). If the Calculation Agent determines that such cumulative economic effect on any Warrant is material, then on the Announcement Event Adjustment Date for such Warrant, the Calculation Agent shall make such adjustment to the exercise, settlement, payment or any other terms of such Warrant as the Calculation Agent determines appropriate to account for such cumulative economic effect, which adjustment shall be effective immediately prior to the Announcement Event Adjustment Date.

“Announcement Cessation Date” means, in respect of an Announcement Event, (i) in the case of an Announcement Event relating to an intention to engage in a transaction that, if completed, would lead to a Merger Event, the date of the first public announcement by the Issuer, any potential counterparty to such transaction or any of their agents or affiliates of its withdrawal from, or the discontinuation of, such transaction, or (ii) in the case of an Announcement Event relating to an intention to purchase or otherwise obtain Shares that, if completed, would lead to a Tender Offer, the date of the first public announcement by any potential offeror in respect of such Tender Offer or any of their agents or affiliates of its withdrawal from, or the discontinuation of, such purchase or other acquisition of Shares. If any such announcement is made after the actual closing time for the regular trading session of on the relevant Exchange, without regard to any after hours or any other trading outside of such regular trading session hours, the Announcement Cessation Date shall be deemed to be the next following Scheduled Trading Day; provided that, for the avoidance of doubt, the occurrence of an Announcement Cessation Date with respect to any transaction shall not preclude the occurrence of a later Announcement Date with respect to such transaction. For purposes hereof, the definition of “Announcement Date” in Section 12.1 of the Equity Definitions shall be amended by (i) replacing the word “leads to the” in the third and the fifth lines thereof with the words “, if completed, would lead to a”; (ii) replacing the words “voting shares” in the fifth line thereof with the word “Shares”; (iii) inserting the words “by any entity” after the word “announcement” in the second and the fourth lines thereof; (iv) replacing the words “a firm” with the word “any bona fide” in the second and fourth lines thereof; (v) inserting the words “or to explore the possibility of engaging in” after the words “engage in” in the second line thereto; and (vi) inserting the words “or to explore the possibility of purchasing or otherwise obtaining” after the word “obtain” in the fourth line thereto.

(iii) Notwithstanding anything to the contrary in this Confirmation, upon the occurrence of one of the following events, with respect to this Transaction, (1) Dealer shall have the right to designate such event an Additional Termination Event and designate an Early Termination Date pursuant to Section 6(b) of the Agreement, and (2) Company shall be deemed the sole Affected Party and the Transaction shall be deemed the sole Affected Transaction:

(A) the consummation of (i) any binding share exchange, consolidation or merger of Company pursuant to which the Shares will be converted into cash, securities or other property; or (ii) any sale, lease or other transfer in one transaction or a series of transactions of all of the consolidated assets of Company and its subsidiaries, taken as a whole, to any person other than one of Company’s subsidiaries; provided, however, that a transaction in which the holders of more than 50% of all classes of common equity of Company immediately prior to such transaction own, directly or indirectly, more than 50% of all classes of common equity of the continuing or surviving corporation or transferee or any direct or indirect parent thereof immediately after the consummation of such transaction shall not be an Additional Termination Event;

(B) There is a default by Company under any of its Public Indebtedness under which there may be outstanding in excess of $25 million, whether such Public Indebtedness now exists or shall hereafter be created, resulting in such Public Indebtedness becoming or being declared due and payable; “Public Indebtedness” shall mean any indebtedness of the Company for money borrowed under notes, bonds or similar instruments offered and sold by the Company in an offering registered with the Securities and Exchange Commission or pursuant to Rule 144A under the Securities Act;

(C) Any “person” or “group” within the meaning of Section 13(d) of the Exchange Act other than Company, any of its subsidiaries or its employee benefit plans, files a Schedule TO or any schedule, form or report under the Exchange Act disclosing that such person or group has become the direct or indirect ultimate “beneficial owner”, as defined in Rule 13d-3 under the Exchange Act, of the common equity of Company representing more than 50% of the ordinary voting power of such common equity;

13

(D) Company’s stockholders approve any plan or proposal for liquidation or dissolution of Company;

(E) the Shares (or other common stock or depositary shares or receipts in respect thereof) cease to be listed or quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market, The NASDAQ Global Market or any other national securities exchange or automated quotation system (or any of their respective successors) for a period of 30 consecutive scheduled trading days;

(F) Dealer, despite using commercially reasonable efforts, is unable or reasonably determines based on the advice of counsel that it is illegal or inadvisable, to hedge its obligations pursuant to this Transaction in the public market without registration under the Securities Act or as a result of any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer).

Notwithstanding any provision of paragraph 9(g)(iii)(A) or (C), however, an Additional Termination Event will not be deemed to have occurred if 90% of the consideration received or exchanged by common stockholders of Company (excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights), in connection with the transaction or transactions otherwise constituting the Additional Termination Event consists of shares of common stock or depositary shares or receipts in respect thereof traded on any of the New York Stock Exchange, The NASDAQ Global Select Market, The NASDAQ Global Market or any other national securities exchange or automated quotation system (or any of their respective successors) or which will be so traded when issued or exchanged in connection with such transaction or transactions (“Publicly Traded Securities”) and as a result of such transaction or transactions the Convertible Notes (as defined in the Purchase Agreement) become convertible into cash, such Publicly Traded Securities or a combination of cash and such Publicly Traded Securities.

(h) No Collateral or Setoff. Notwithstanding any provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Company hereunder are not secured by any collateral. In addition, obligations under this Transaction shall not be netted, recouped or set off (including pursuant to Section 6 of the Agreement) against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other obligations of the parties shall be netted, recouped or set off (including pursuant to Section 6 of the Agreement) against obligations under the Transaction, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and each party hereby waives any such right of setoff, netting or recoupment; provided that both parties agree that subparagraph (ii) of Section 2(c) of the Agreement shall apply to the Transaction.

(i) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If, in respect of this Transaction, an amount is payable by Company to Dealer, (i) pursuant to Sections 12.2, 12.3, 12.6, 12.7 or 12.9 of the Equity Definitions (except in the event of an Insolvency, Nationalization, Tender Offer or Merger Event in which the consideration or proceeds to be paid to holders of shares consists solely of cash) or (ii) pursuant to Section 6(d)(ii) of the Agreement (except in the event of an Event of Default in which Company is the Defaulting Party or a Termination Event in which Company is the Affected Party, other than an Event of Default of the type described in (x) Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or (y) a Termination Event of the type described in Section 5(b)(i), (ii), (iii), (iv), (v) or (vi) of the Agreement, in the case of both (x) and (y), resulting from an event or events outside Company’s control) (a “Payment Obligation”), Company shall satisfy any such Payment Obligation by the Share Termination Alternative (as defined below), unless Company elects to satisfy any such Payment Obligation by delivering cash (in which case the provisions of Sections 12.2, 12.3, 12.6, 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as the case may be, shall apply in lieu of the provisions of this paragraph 9(i)), by giving irrevocable telephonic notice to Dealer, confirmed in writing within one

14

Scheduled Trading Day, no later than 12:00 p.m. New York local time on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable where such notice shall include a representation and warranty from Company that it is not, as of the date of the telephonic notice and the date of such written notice, aware of any “material non-public information” (within the meaning of Section 10(b) of the Exchange Act and the rules promulgated thereunder) concerning itself or the Shares. Notwithstanding the foregoing, satisfaction of a Payment Obligation in the Share Termination Alternative as set forth in this clause shall only apply to this Transaction and, notwithstanding anything to the contrary in the Agreement, (1) separate amounts shall be calculated with respect to (a) the Transaction and (b) all other Transactions under the Agreement, and (2) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement, subject to, in the case of clause (a), Company’s right to deliver cash in satisfaction of any Payment Obligation hereunder.

Share Termination Alternative:	If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “Share Termination Payment Date”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or pursuant to Section 6(d)(ii) of the Agreement, subject to paragraph (j)(i) below, in satisfaction, subject to paragraph (j)(ii) below, of the Payment Obligation in the manner reasonably requested by Dealer free of payment.
Share Termination Delivery Property:	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.
Share Termination Unit Price:	The value to Dealer of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its discretion by commercially reasonable means. The Calculation Agent shall notify Company of such Share Termination Unit Price at the time of notification of the Payment Obligation. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in paragraph (j)(i) below, the Share Termination Unit Price shall be determined by the discounted price applicable to such Share Termination Delivery Units. In the case of a Registration Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as set forth in paragraph (j)(ii) below, the Share Termination Unit Price shall be the Settlement Price on the Merger Date, the Announcement Date (in the case of a Nationalization, Insolvency or Delisting) or the Early Termination Date, as applicable.
Share Termination Delivery Unit:	In the case of a Termination Event, Event of Default or Delisting, one Share or, in the case of Nationalization, Insolvency, Tender Offer or Merger Event, a unit consisting of the number or amount of each type of property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency, Tender Offer or Merger Event. If such Nationalization, Insolvency, Tender Offer or Merger Event involves a choice of consideration to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.
Failure to Deliver:	Inapplicable

15

Other applicable provisions: If Share Termination Alternative is applicable, the provisions of Sections 9.1(c), 9.8, 9.9, 9.11, 9.12 and 10.5 (as modified above) of the Equity Definitions will be applicable, except that the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by excluding any representations therein relating to restrictions, obligations, limitations or requirements under applicable securities laws as a result of the fact that Company is the Issuer of the Shares or any portion of the Share Termination Delivery Units, and that all references in such provisions to “Physically-Settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to this Transaction means that Share Termination Alternative is applicable to this Transaction.

(j) Registration/Private Placement Procedures. If, in the commercially reasonable judgment of Dealer based on the advice of counsel, following any delivery of Shares or Share Termination Delivery Property to Dealer hereunder, such Shares or Share Termination Delivery Property would be in the hands of Dealer subject to any applicable restrictions with respect to any registration or qualification requirement or prospectus delivery requirement for such Shares or Share Termination Delivery Property pursuant to any applicable federal or any applicable material restrictions pursuant to any applicable state securities law (including, without limitation, any such requirement arising under Section 5 of the Securities Act as a result of such Shares or Share Termination Delivery Property being “restricted securities”, as such term is defined in Rule 144 under the Securities Act, or as a result of the sale of such Shares or Share Termination Delivery Property being subject to paragraph (c) of Rule 145 under the Securities Act) (such Shares or Share Termination Delivery Property, “Restricted Shares”), then delivery of such Restricted Shares shall be effected pursuant to either clause (i) or (ii) below at the election of Company, unless Dealer waives the need for registration/private placement procedures set forth in (i) and (ii) below. Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants exercised or deemed exercised on any Expiration Date, Company shall, if applicable, elect, prior to the first Settlement Date for the first Expiration Date, a Private Placement Settlement or Registration Settlement for all deliveries of Restricted Shares for all such Expiration Dates which election shall be applicable to all Settlement Dates for such Warrants and the procedures in clause (i) or clause (ii) below shall apply for all such delivered Restricted Shares on an aggregate basis commencing after the final Settlement Date for such Warrants. The Calculation Agent shall make reasonable adjustments to settlement terms and provisions under this Confirmation to reflect a single Private Placement or Registration Settlement for such aggregate Restricted Shares delivered hereunder.

(i) If Company elects to settle the Transaction pursuant to this clause (i) (a “Private Placement Settlement”), then delivery of Restricted Shares by Company shall be effected in accordance with customary private placement procedures for private placements of equity offerings of substantially similar size reasonably acceptable to Dealer; provided that Company may not elect a Private Placement Settlement if, on the date of its election, it has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(2) of the Securities Act for the sale by Company to Dealer (or any affiliate designated by Dealer) of the Restricted Shares or the exemption pursuant to Section 4(1) or Section 4(3) of the Securities Act for resales of the Restricted Shares by Dealer (or any such affiliate of Dealer). The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Restricted Shares by Dealer), opinions and certificates, and such other documentation as is customary for private placements of equity offerings of substantially similar size, all reasonably acceptable to Dealer. In the case of a Private Placement Settlement, Dealer shall determine the appropriate discount to the Share Termination Unit Price (in the case of settlement of Share Termination Delivery Units pursuant to paragraph (i) above) or any Settlement Price (in the case of settlement of Shares pursuant to paragraph 2 above) applicable to such Restricted Shares in a commercially reasonable manner to account for the lack of marketability and illiquidity of such Restricted Shares and appropriately adjust the number of such Restricted Shares to be delivered to Dealer hereunder; provided that in no event shall such number be greater than 2 times the Number of Warrants multiplied by the Warrant Entitlement (the “Maximum Amount”). Notwithstanding the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Exchange Business Day following notice by Dealer to Company, of such applicable discount and the number of

16

Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Share Termination Payment Date (in the case of settlement of Share Termination Delivery Units pursuant to paragraph (i) above) or on the Settlement Date for such Restricted Shares (in the case of settlement in Shares pursuant to paragraph 2 above).

In the event Company shall not have delivered the full number of Restricted Shares otherwise applicable as a result of the proviso above relating to the Maximum Amount (such deficit, the “Deficit Restricted Shares”), Company shall be continually obligated to deliver, from time to time until the full number of Deficit Restricted Shares have been delivered pursuant to this paragraph, Restricted Shares when, and to the extent, that (i) Shares are repurchased, acquired or otherwise received by Company or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (ii) Company authorized any unissued Shares reserved for issuance in respect of other transactions prior to such date which prior to the relevant date become no longer so reserved and (iii) Company additionally authorizes any unissued Shares that are not reserved for other transactions. At such time as there may be Deficit Restricted Shares, Company shall promptly notify Dealer of the occurrence of any of the foregoing events (including the number of Shares subject to clause (i), (ii) or (iii) and the corresponding number of Restricted Shares to be delivered) and promptly deliver such Restricted Shares thereafter.

(ii) If Company elects to settle the Transaction pursuant to this clause (ii) (a “Registration Settlement”), then Company shall file and use its reasonable best efforts to make effective under the Securities Act a registration statement or supplement or amend an outstanding registration statement in form and substance reasonably satisfactory to Dealer, to cover the resale of such Restricted Shares (and any Company Make-whole Shares) in accordance with customary resale registration procedures for registered secondary offerings of a substantially similar size, including covenants, conditions, representations, underwriting discounts (if applicable), commissions (if applicable), indemnities due diligence rights, opinions and certificates, and such other documentation as is customary for equity resale underwriting agreements for registered secondary offerings of a substantially similar size, all reasonably acceptable to Dealer. If Dealer, in its good faith and reasonable discretion, is not satisfied with such procedures and documentation, Private Placement Settlement shall apply. If Dealer is satisfied with such procedures and documentation, it shall sell the Restricted Shares pursuant to such registration statement during a period (the “Resale Period”) commencing on the Exchange Business Day following delivery of such Restricted Shares (and any Company Make-whole Shares) (which, for the avoidance of doubt, shall be (x) any Settlement Date in the case of an exercise of Warrants prior to the first Expiration Date pursuant to paragraph 2 above, (y) the Share Termination Payment Date in case of settlement in Share Termination Delivery Units pursuant to paragraph (i) above or (z) the Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants) and ending on the earliest of (i) the Exchange Business Day on which Dealer completes the sale of all Restricted Shares or, in the case of settlement of Share Termination Delivery Units, a sufficient number of Restricted Shares so that the realized net proceeds of such sales exceed the Payment Obligation (as defined above) and (ii) the date upon which all Restricted Shares have been sold or transferred pursuant to Rule 144 (or similar provisions then in force) or Rule 145(d)(1) or (2) (or any similar provision then in force) under the Securities Act.

(iii) (A) If (ii) above is applicable and the Net Share Settlement Amount or the Payment Obligation, as applicable, exceeds the realized net proceeds from such resale, or if (i) above is applicable and the Freely Tradable Value (as defined below) of the Net Share Settlement Amount or the Payment Obligation (in each case as adjusted pursuant to (i) above), as applicable, exceeds the realized net proceeds from such resale, Company shall transfer to Dealer by the open of the regular trading session on the Exchange on the Exchange Trading Day immediately following the last day of the Resale Period a number of Shares (“Company Make-whole Shares”) in an amount that, based on the Settlement Price on the last day of the Resale Period (as if such day was the “Valuation Date” for purposes of computing such Settlement Price), has a dollar value equal to the amount of such excess (the “Company Additional Amount”), or if Company so elects, an amount in cash equal to the Company Additional Amount. The Resale Period shall continue to enable the sale of the Company Make-whole Shares. If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration Settlement or Private Placement Settlement, as the case may be, shall apply. This provision shall be applied successively until the Additional Amount is equal to zero. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Amount.

17

If (ii) above is applicable and the realized net proceeds from such resale (including the sale of any Company Make-whole Shares) exceed the Net Share Settlement Amount or the Payment Obligation, as applicable, or if (i) above is applicable and the realized net proceeds from such resale (including the sale of any Company Make-whole Shares) exceed the Freely Tradeable Value (as defined below) of the Net Share Settlement Amount or the Payment Obligation (in each case as adjusted pursuant to (i) above), as applicable, Dealer shall transfer to Company the amount of such excess (the “Dealer Additional Amount”) in a number of Shares (“Dealer Make-whole Shares”) that, based on the Settlement Price on the last day of the Resale Period (as if such day was the Valuation Date for purposes of computing such Settlement Price), has a value equal to the Dealer Additional Amount, or, at Company’s option, in cash in an amount equal to the Dealer Additional Amount. The transfer of the Dealer Additional Amount shall be made (x) if in cash, by the open of the regular trading session on the Exchange on the Exchange Trading Day immediately following the last day of the Resale Period, and (y) if in Shares, one Settlement Cycle following the date Dealer is able, using commercially reasonable efforts, to purchase Dealer Make-whole Shares. This provision shall be applied successively until the Dealer Additional Amount is equal to zero.

“Freely Tradeable Value” means the value of the number of Shares delivered to Dealer which such Shares would have if they were freely tradeable (without prospectus delivery) upon receipt by Dealer, as determined by the Calculation Agent by commercially reasonable means.

(iv) Without limiting the generality of the foregoing, Company agrees that any Restricted Shares delivered to Dealer, as purchaser of such Restricted Shares, (i) may be transferred by and among Dealer and its affiliates and Company shall effect such transfer without any further action by Dealer and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after any Settlement Date for such Restricted Shares, Company shall promptly remove, or cause the transfer agent for such Restricted Shares to remove, any legends referring to any such restrictions or requirements from such Restricted Shares upon delivery by Dealer (or such affiliate of Dealer) to Company or such transfer agent of seller’s and broker’s representation letters customarily delivered by Dealer in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Dealer (or such affiliate of Dealer).

If the Private Placement Settlement or the Registration Settlement shall not be effected as set forth in clauses (i) or (ii), as applicable, then failure to effect such Private Placement Settlement or such Registration Settlement shall constitute an Event of Default with respect to which Company shall be the Defaulting Party.

(k) Limit on Beneficial Ownership. Except as provided below in this paragraph (k), notwithstanding any other provision to the contrary in this Confirmation, in no event shall Dealer be entitled to receive, or shall be deemed to receive, Shares to the extent that, immediately upon giving effect to such receipt of such Shares,

(i) the Option Equity Percentage (as defined below) exceeds 4.9%,

(ii) Dealer, Dealer Group (as defined below) or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a “Dealer Person”) under any relevant state corporate law or other state, federal or local laws, regulations or regulatory orders applicable to ownership of Shares (“Applicable Laws”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership in excess of a number of Shares equal to (x) the number of Shares that, in the good faith determination of the relevant Dealer Person, would give rise to materially burdensome reporting or registration obligations or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person under Applicable Laws (including, without limitation, “interested stockholder” or “acquiring person” status under Section 203 of the Delaware General Corporation Law, but excluding any report or filing required pursuant to Section 13 of the Exchange Act and the rules promulgated thereunder) and with respect to which such requirements have not been met or the relevant approval has not been received minus (y) 1.0% of the number of Shares outstanding on the date of determination,

18

(iii) the Maritime Law Ownership Percentage (as defined below) of the Maritime Law Dealer Group (as defined below) would be greater than 4.9% of the outstanding Shares, unless Dealer has established to the reasonable satisfaction of the Company that it (or the person designated to take delivery) is a citizen of the United States for purposes of the U.S. coastwise trade under the Maritime Laws (as defined below),

(iv) such Shares would reasonably be anticipated by the Company to be “Excess Shares” (“Excess Shares”) as defined in the Company’s Second Restated Certificate of Incorporation (the “Certificate”) or

(v) such Shares, in the good faith determination of the Company, would cause the Company to cease to be qualified under Maritime Laws (as defined below) or Applicable Laws to own and operate vessels in the coastwise trade of the United States (each of clause (i) through (iv) above and this clause (v), an “Ownership Limitation”).

If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of an Ownership Limitation, the Company’s obligation to make such delivery shall not be extinguished and the Company shall make such delivery as promptly as practicable after, but in no event later than three Exchange Business Days after, Dealer gives notice to the Company that such delivery would not result in any of such Ownership Limitations being breached. Such notice by Dealer will include details sufficient to support the position taken by Dealer in such notice.

The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (i) the number of Shares that Dealer and any of its affiliates subject to aggregation with Dealer, for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, and all persons who may form a “group” (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with Dealer (“Dealer Group”) “beneficially owns” (within the meaning of Section 13 of the Exchange Act) on such day, other than any Shares so owned as a hedge of the Transaction, and (ii) the product of the Number of Warrants and the Warrant Entitlement and (B) the denominator of which is the number of Shares outstanding on such day. “Maritime Law Ownership Percentage” means the ownership, as construed under the Maritime Laws, of Shares by Dealer or any person whose ownership would be aggregated with that of Dealer or Dealer’s parent entity under the Maritime Laws (collectively, the “Maritime Law Dealer Group”). “Maritime Laws” means, collectively and without duplication, Chapters 121 and 505 of Title 46 of the United States Code and any successor or replacement statute thereto, and the regulations promulgated under such Title or successor or replacement statute or, to the extent remaining in force, under any predecessor statute, in each case as amended or supplemented from time to time.

The Company represents and warrants that, assuming the accuracy of any factual information regarding Dealer that is provided by Dealer to the Company upon the Company’s request, any Shares delivered by the Company to Dealer pursuant to the Transaction shall not be Excess Shares, and the issuance and delivery of such Shares shall have been approved by the board of directors of the Company. If Dealer designates any person to receive any Shares pursuant to Section 9(t), clauses (iii), (iv) and (v) of this Section 9(k) shall apply as if such person were Dealer. If the Company is unable to deliver any Shares to Dealer as a result of this Section 9(k), notwithstanding Company’s continuing obligation to deliver such Shares as described herein, the Company may at any time following the Settlement Date, upon one Exchange Business Day’s prior written notice to Dealer, elect to deliver cash in lieu of any or all such Shares, in which case the Shares for which cash delivery has been so elected shall be valued by the Calculation Agent in a commercially reasonable manner over such time period as the Calculation Agent reasonably determines appropriate in light of the liquidity of the Shares at such time and applicable law and related regulations, policies and procedures. The Company’s right to elect cash pursuant to the foregoing sentence shall be subject to the Company giving representations, warranties and covenants customary for transactions under Rule 10b5-1 under the Exchange Act and satisfactory to Dealer. The Company shall promptly notify Dealer if at any time either (i) any purported transfer of any shares of any class or series of capital stock of the Company is void and ineffective pursuant to Section 2 of Article Twelve of the Certificate or (ii) any shares of any class or series of capital stock of the Company are “Excess Shares” pursuant to Section 3 of Article Twelve of the Certificate. The Company covenants that it shall provide prompt written notice to Dealer upon having actual knowledge that more than 10% of the aggregate Shares outstanding are owned by persons other than citizens of the United States for purposes of the U.S. coastwise trade under the Maritime Laws and upon becoming aware of each additional 5% thereafter.

19

The Company shall provide Dealer with a copy of any filings submitted to any regulatory authority relating to the Company’s or the Company’s stockholders’ citizenship under the Maritime Laws so long as Dealer (or any assignee of Dealer) has agreed to keep any such filings and the information contained therein confidential on terms reasonably acceptable to the Company and Dealer. Dealer acknowledges that Dealer will not have any rights as a holder of the Company’s common stock with respect to Shares, prior to the delivery thereof hereunder, that the Company is unable to deliver as a result of this Section 9(k). The Company acknowledges that, as a result of this Section 9(k), it will not treat Dealer (or any affiliate or designee of Dealer) as the owner, for any purpose (including, without limitation, for purposes of the Maritime Laws or Article Twelve of the Certificate), of Shares, prior to the delivery of such Shares hereunder, that the Company is unable to deliver as a result of this Section 9(k). For purposes of this Section 9(k), the term “Dealer” shall include any of the Dealer’s permitted successors or assigns.

(l) Share Deliveries. Company acknowledges and agrees that, to the extent the holder of this Warrant is not then an affiliate, as such term is used in Rule 144 under the Securities Act, of Company and has not been such an affiliate of Company for 90 days (it being understood that Dealer will not be considered an affiliate of Company solely by reason of its receipt of or right to receive Shares pursuant to this Transaction), and otherwise satisfies all holding period and other requirements of Rule 144 of the Securities Act applicable to it, any delivery of Shares or Share Termination Delivery Property hereunder at any time after 6 months from the Trade Date (or 1 year from the Trade Date if, at such time, informational requirements of Rule 144(c) are not satisfied with respect to Company) shall be eligible for resale under Rule 144 of the Securities Act, and Company agrees to promptly remove, or cause the transfer agent for such Shares or Share Termination Delivery Property to remove, any legends referring to any restrictions on resale under the Securities Act from the certificates representing such Shares or Share Termination Delivery Property. Company further agrees and acknowledges that Dealer shall run a holding period under Rule 144 under the Securities Act with respect to the Warrants and/or any Shares or Share Termination Delivery Property delivered hereunder notwithstanding the existence of any other transaction or transactions between Company and Dealer relating to the Shares. Company further agrees that Shares or Share Termination Delivery Property delivered hereunder prior to the date that is 6 months from the Trade Date (or 1 year from the Trade Date, if, at such time, informational requirements of Rule 144(c) are not satisfied with respect to Company) may be freely transferred by and among Dealer and its affiliates, and Company shall effect such transfer without any further action by Dealer. Notwithstanding anything to the contrary herein, Company agrees that any delivery of Shares or Share Termination Delivery Property shall be effected by book-entry transfer through the facilities of DTC, or any successor depositary, if, at the time of delivery, the certificates representing such Shares or Share Termination Delivery Property would not contain any restrictive legend as described above. Notwithstanding anything to the contrary herein, to the extent the provisions of Rule 144 of the Securities Act or any successor rule are amended, or the applicable interpretation thereof by the Securities and Exchange Commission or any court changes after the Trade Date, including without limitation to lengthen or shorten the holding periods, the agreements of Company herein shall be deemed modified to the extent necessary, in the opinion of outside counsel of Company, to comply with Rule 144 of the Securities Act, including Rule 144, as in effect at the time of delivery of the relevant Shares or Share Termination Delivery Property.

(m) Additional Termination Events. (i) If within the period commencing on the Trade Date and ending on the first anniversary of the Premium Payment Date, Dealer reasonably determines that it is advisable to terminate a portion of the Transaction so that Dealer’s related hedging activities will comply with applicable securities laws, rules or regulations, an Additional Termination Event shall occur in respect of which (1) Company shall be the sole Affected Party and (2) the Transaction shall be the sole Affected Transaction, and (ii) the Warrant Equity Percentage exceeds 15.9%. The “Warrant Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Warrants and the Warrant Entitlement and (2) the aggregate number of Shares underlying any other warrants purchased by Dealer from Company, and (B) the denominator of which is the number of Shares outstanding.

(n) Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to this Transaction. Each party (i) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into this Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

20

(p) Maximum Share Delivery. Notwithstanding any other provision of this Confirmation or the Agreement, in no event will Company be required to deliver more than the lesser of (i) the Maximum Amount of Shares in the aggregate to Dealer in connection with this Transaction and (ii) 2,816,620 Shares, subject to the provisions regarding Deficit Restricted Shares.

(q) Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights with respect to the Transaction that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Company; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Company of its obligations and agreements with respect to the Transaction; provided further that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.

(r) Securities Contract. Each of Dealer and Company agrees and acknowledges that Dealer is one or more of a “financial institution” and “financial participant” within the meaning of sections 101(22) and 101(22A) of Title 11 of the United States Code (the “Bankruptcy Code”). The parties further agree and acknowledge (A) that this Confirmation is a “securities contract,” as such term is defined in Section 741(7) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value”, “payment amount” or “other transfer obligation” within the meaning of section 362 of the Bankruptcy Code and is a “settlement payment” (as such term is defined in Section 741(8) of the Bankruptcy Code) or a “transfer” within the meaning of section 546 of the Bankruptcy Code, and (B) that is the parties are entitled to the protections afforded by, among other sections, section 362(b)(6), 362(b)(27), 362(o), 546(e), 546(j), 548(d)(2), 555 and 561 of the Bankruptcy Code.

(s) Right to Extend. Dealer may postpone any Exercise Date, Settlement Date or any other date of valuation or delivery with respect to some or all of the relevant Warrants (in which case the Calculation Agent may make appropriate adjustments to the relevant number of Warrants being exercised), if Dealer determines, in its good faith and commercially reasonable judgment based on the advice of counsel, that such action is advisable to preserve Dealer’s Hedging Activity hereunder in light of existing liquidity conditions to enable Dealer to effect purchases of Shares in connection with its Hedging Activity hereunder in a manner that would, if Dealer were the Company or an affiliated purchaser of the Company, be in compliance with applicable legal and regulatory requirements.

(t) Method of Delivery. Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing JPMorgan to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Company, JPMorgan may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform JPMorgan’s obligations in respect of the Transaction and any such designee may assume such obligations. JPMorgan shall be discharged of its obligations to Company to the extent of any such performance.

(u) Role of Agent. Each party agrees and acknowledges that (i) J.P. Morgan Securities LLC, an affiliate of JPMorgan (“JPMS”), has acted solely as agent and not as principal with respect to the Transaction and (ii) JPMS has no obligation or liability, by way of guaranty, endorsement or otherwise, in any manner in respect of the Transaction (including, if applicable, in respect of the settlement thereof). Each party agrees it will look solely to the other party (or any guarantor in respect thereof) for performance of such other party’s obligations under the Transaction.

Any such recording may be submitted in evidence to any court or in any Proceeding for the purpose of establishing any matters pertinent to this Transaction.
