 Re: Call Option Transaction

 The purpose of this letter agreement is to confirm the terms and conditions of the Transaction entered into between Jefferies International Limited
(“Dealer”), which is authorized and regulated in the United Kingdom for the conduct of designated investment business by the Financial Services Authority, and Hornbeck Offshore Services, Inc. (“Counterparty”) on the
Trade Date specified below (the “Transaction”). The time of the Transaction is available upon request. This letter agreement constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below.
This Confirmation shall replace any previous agreements and serve as the final documentation for this Transaction. 
 The definitions and provisions
contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation. In
the event of any inconsistency between the Equity Definitions and this Confirmation, this Confirmation shall govern. Certain defined terms used herein have the meanings assigned to them in the Offering Memorandum dated November 7, 2006 (the
“Offering Memorandum”) relating to the USD 220,000,000 principal amount of 1.625% Convertible Senior Notes due 2026, (the “Convertible Notes” and each USD 1,000 principal amount of Convertible Notes, a
“Convertible Note”) issued by Counterparty pursuant to an Indenture to be dated November 13, 2006 between Counterparty and Wells Fargo Bank, N.A., as trustee (without giving effect to any subsequent amendment, modification or
waiver, the “Indenture”). In the event of any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. 
 Each party is hereby advised, and each such party acknowledges, that the other party has engaged in, or refrained from engaging in, substantial financial
transactions and has taken other material actions in reliance upon the parties’ entry into the Transaction to which this Confirmation relates on the terms and conditions set forth below. 

 1. This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of
the Transaction to which this Confirmation relates. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Dealer and Counterparty had
executed an agreement in such form (but without any Schedule except for (i) the election of the laws of the State of New York as the governing law, and (ii) the election of US Dollars (“USD”) as the Termination Currency)
on the Trade Date. In the event of any inconsistency between provisions of that Agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction to which this Confirmation relates. The parties hereby agree that no
Transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement.

 5 

			
	Valuation Time:	 	At the close of trading of the regular trading session on the Exchange; provided that if the principal trading session is extended, the Calculation Agent shall determine the Valuation Time in its
reasonable discretion.
		
	Market Disruption Event:	 	Section 6.3(a) of the Equity Definitions is hereby amended by (x) deleting the phrase “during the one hour period that ends at the relevant Valuation Time” in Section 6.3(a)(ii) and replacing it
with the phrase “at any time prior to 1:00 p.m. on such Scheduled Trading Day of an aggregate one half hour period” and (y) deleting the phrase “or (iii) an Early Closure”.

 Settlement Terms: 
  

			
	Settlement Date:	 	In respect of an Exercise Date, the settlement date for the Shares and cash (in respect of fractional shares) to be delivered under the Relevant Convertible Notes under the terms of the Indenture;
provided that if such a day is not the third Currency Business Day following the last day of the related Observation Period, Dealer shall use its reasonable efforts to make deliveries on the Settlement Date for the Relevant Convertible Notes
(subject to receipt of a prior notice from Issuer sufficiently in advance of such Settlement Date) and if, notwithstanding such reasonable efforts, the Dealer is unable to effect the delivery on such day, then it shall be the third Currency Business
Day following the last day of the related Observation Period.
		
	Delivery Obligation:	 	In lieu of the obligations set forth in Sections 8.1 and 9.1 of the Equity Definitions, and subject to “Notice of Exercise” above, in respect of an Exercise Date occurring on or with respect to
a Conversion Date, Dealer will deliver to Counterparty, on the related Settlement Date, the product of (x) the Applicable Percentage and (y) an aggregate number of Shares and an aggregate amount of cash (in respect of fractional Shares) in excess of
(i) USD 1,000 (if Counterparty has elected to settle the Relevant Convertible Notes in cash and Shares) or (ii) the number of Shares equivalent to USD 1,000, as determined by the Calculation Agent based on the sum, for all Trading Days in the
Observation Period, of a respective number of Shares equal to USD 40

  

 6 

			
		 	divided by the Daily VWAP (as defined in the Indenture) for each such Trading Day (if Counterparty has elected to settle the Relevant Convertible Notes in Shares only) that Counterparty is obligated to
deliver to the holder(s) of the Relevant Convertible Notes converted on such Conversion Date pursuant to Section 12.01(d) of the Indenture (the “Convertible Obligation”); provided that, if the Relevant Convertible Notes are
being converted in connection with any Fundamental Change (as defined in the Indenture), (a) the Calculation Agent shall determine an amount that would be payable by Dealer to Counterparty pursuant to Section 6(e)(ii)(1) of the Agreement (for
purposes of such determination, the Calculation Agent shall not be taking into account the amount deliverable to the holder(s) of the Relevant Convertible Notes pursuant to Section 12.03 of the Indenture) if (x) the Number of Options were equal to
the product of the Applicable Percentage and the number of the Relevant Convertible Notes and (y) the Fundamental Change were an Additional Termination Event occurring on the effective date for the Fundamental Change with Counterparty as the sole
Affected Party (the “Fair Value Amount”), and (b) to the extent that a number of additional Shares that Counterparty is obligated to deliver to holder(s) of the Relevant Convertible Notes as a result of any adjustments to the
Conversion Rate pursuant to Section 12.03 of the Indenture in respect of such Fundamental Change exceeds the number of Shares equal to the Fair Value Amount (such number of Shares to be determined by the Calculation Agent based on the daily VWAP of
the Shares on the effective date of the Fundamental Change), then the “Delivery Obligation” shall be determined excluding any such excess Shares. For the avoidance of doubt, if the “Conversion Obligation”, as defined in the
Indenture, is less than or equal to USD 1,000 (or a number of Shares equivalent to USD 1,000 determined as set forth above), Dealer will have no delivery obligation hereunder.
		
	Notice of Delivery Obligation:	 	No later than the Exchange Business Day immediately following the last day of the “Observation Period”, as defined in the Indenture, Counterparty or the Trustee on behalf of Counterparty shall
give Dealer notice

  

 7 

			
		 	of the final number of Shares and the amount of cash (in respect of fractional shares) comprising the Convertible Obligation (it being understood, for the avoidance of doubt, that the requirement of
Counterparty to deliver such notice shall not limit Counterparty’s obligations with respect to Notice of Exercise, as set forth above, in any way).
		
	Other Applicable Provisions:	 	To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9, 9.11, 9.12 and 10.5 of the Equity Definitions will be applicable, except that all references in
such provisions to “Physical Settlement” shall be read as references to “Net Share Settlement”; and provided 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 Buyer is the Issuer of the Shares. “Net Share Settlement” in relation to any
Option means that Dealer is obligated to deliver Shares hereunder.
	  
 3. Additional Terms applicable to the Transaction:
  
 Adjustments applicable to the Transaction:
  

	Method of Adjustment:	 	Calculation Agent Adjustment, and means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any adjustment to the Conversion Rate of the Convertible Notes pursuant to the Indenture
(other than Section 12.03 of the Indenture, except to the extent provided under “Delivery Obligation” above), the Calculation Agent will make a corresponding adjustment to any one or more of the Number of Options, the Option Entitlement
and any other variable relevant to the exercise, settlement or payment for the Transaction. Immediately upon the occurrence of any adjustment contemplated in Section 12.03 of the Indenture (an “Adjustment Event”), Counterparty shall
notify the Calculation Agent of such Adjustment Event; and once the adjustments to be made to the terms of the Indenture and the Convertible Notes in respect of such Adjustment Event have been determined, Counterparty shall immediately notify the
Calculation Agent in writing of the details of such adjustments. 

  

 8 

			
	Potential Adjustment Events:	 	Notwithstanding Section 11.2(e) of the Equity Definitions, a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in Section 12.02 of the Indenture that would
result in an adjustment to the Conversion Rate of the Convertible Notes; provided that in no event shall there be any adjustment hereunder as a result of an adjustment to the Conversion Rate pursuant to Section 12.03 of the Indenture, except
to the extent provided under “Delivery Obligation” above.

 Extraordinary Events applicable to the Transaction: 
  

			
	Merger Events:	 	Notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in Section 12.05 of the Indenture.
		
	Tender Offers:	 	Notwithstanding Section 12.1(d) of the Equity Definitions, a “Tender Offer” means the occurrence of any event or condition set forth in Section 12.02(e) of the Indenture and, upon the occurrence
of such an event, adjustments set forth under “Method of Adjustment” above shall apply.
		
	Consequences of Merger Events:	 	Notwithstanding Section 12.2 of the Equity Definitions, upon the occurrence of a Merger Event, the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture
to any one or more of the nature of the Shares, Number of Options, the Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction; provided however that such adjustment shall be made without
regard to any adjustment to the Conversion Rate for the issuance of additional shares as set forth in Section 12.03 of the Indenture, except to the extent provided under “Delivery Obligation” above. Notwithstanding the foregoing, upon the
occurrence of a Merger Event that constitutes a “Public Acquirer Change in Control”, as defined in the Indenture, with respect to which Counterparty elects to adjust the terms of the Convertible Notes in

  

 9 

			
		 	accordance with Section 12.04 of the Indenture (such a Public Acquirer Change in Control, a “PACC Event”), subject to compliance with the proviso to this sentence, the Calculation Agent
will adjust any one or more of the nature of the Shares, the Number of Options, the Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction to the extent required to preserve the fair value of
the Transaction to Dealer (such adjustments, the “PACC Adjustments”); provided that, as a condition precedent to the adjustments contemplated above, Counterparty and, if Counterparty is not the issuer of the “Public
Acquirer Common Stock”, as defined in the Indenture, the issuer of the Public Acquirer Common Stock, shall, prior to the effective date of such PACC Event, have entered into such documentation containing representations, warranties and
agreements relating to securities laws and other issues as requested by Dealer that Dealer determined, in its reasonable discretion, to be reasonably necessary or appropriate to allow Dealer to continue as a party to the Transaction, as adjusted,
and to preserve its hedge unwind, hedge leg in and other hedging activities in connection with the Transaction in a manner compliant with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures
applicable to Dealer.
		
	Nationalization, Insolvency or Delisting:	 	Cancellation and Payment (Calculation Agent Determination); provided that Counterparty may elect settlement of the related obligation in accordance with Section 9(k) below; provided, further
that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not re-listed, re-traded or re-quoted within 30 Exchange
Business Days following such Delisting on a U.S. national or regional securities exchange or an established automated over-the-counter trading market in the U.S.; if the Shares are re-listed, re-traded or re-quoted within 30 Scheduled Trading Days
following such Delisting on any U.S. national or regional securities exchange or an established automated over-the-counter trading market in the U.S., such exchange or quotation system shall thereafter be deemed to be the Exchange.

other similar officer, director or employee benefit plans; 
 (s) prior to the Trade Date, neither the Counterparty nor any of its
affiliates has taken any action which is designed to or which has constituted or which might have been expected to cause or result in stabilization or manipulation of the price of any security of the Counterparty in connection with the offering of
the Convertible Notes; 
 (t) none of the Counterparty or any of its subsidiaries is in violation of its certificate of incorporation or
certificate of formation, or its bylaws or limited liability company agreement (or other organizational documents), or in default in the performance or observance of any material obligation, covenant or condition contained in any indenture,
mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound, other than such defaults that individually or in the aggregate would not have a Material
Adverse Effect; and 
 (u) other than as set forth in the Offering Memorandum, there are no legal or governmental proceedings pending to
which the Counterparty or any of its subsidiaries is a party or of which any property of the Counterparty or any of its subsidiaries is the subject which, if determined adversely to the Counterparty or any of its subsidiaries, would individually or
in the aggregate have a Material Adverse Effect; and, to the best of the Counterparty’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others. 
 (B) Each party makes to the other the representations and warranties set forth in Sections 3(a) through (f) of the Agreement with respect to the Agreement as
supplemented by this Confirmation; provided that Dealer makes the representation and warranty set forth in Section 3(e) and Counterparty makes the representation and warranty set forth in Section 3(f). In addition, each of Dealer
and Counterparty acknowledges that the offer and sale of the Transaction to it is intended to be exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), by virtue of Section 4(2) thereof.
Accordingly, Counterparty represents and warrants to Dealer that (i) it has the financial ability to bear the economic risk of its investment in the Transaction and is able to bear a total loss of its investment and its investments in and
liabilities in respect of the Transaction, which it understands are not readily marketable, are not disproportionate to its net worth, and it is able to bear any loss in connection with the Transaction, including the loss of its entire investment in
the Transaction, (ii) it is an “accredited investor” as that term is defined in Regulation D as promulgated under the Securities Act, (iii) it is entering into the Transaction for its own account and without a view to the
distribution or resale thereof, (iv) the assignment, transfer or other disposition of the Transaction has not been and will not be registered under the Securities Act and is restricted under this Confirmation, the Securities Act and state
securities laws, and (v) its financial condition is such that it has no need for liquidity with respect to its investment in the Transaction and no need to dispose of any portion thereof to satisfy any existing or contemplated undertaking or
indebtedness and is capable of assessing the merits of and understanding (on its own behalf or through independent professional advice), and understands and accepts, the terms, conditions and risks of the Transaction.

 9. Other Provisions: 
 (a) Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to the matters set forth in Section 3(a) of the Agreement and Section 8(A)(g) of this
Confirmation. 
 (b) Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of
Shares, give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day, and, if such notice relates to material non-public information at the time, simultaneously publicly announce such information, if following
such repurchase, the Notice Percentage as determined on such day is (i) greater than 4.5% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such
Repurchase Notice, greater than the Notice Percentage as of the date hereof). The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of which is the product of the Number of Options and the
Option Entitlement and the denominator of which is the number of Shares outstanding on such day. 
 (c) Regulation M.
Counterparty is not on the date hereof engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of any securities of Counterparty, other than a
distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Counterparty shall not, until the second Scheduled Trading Day immediately following the Trade Date, engage in any such distribution.

 (d) No Manipulation. Counterparty is not entering into this Transaction to create actual or apparent trading activity
in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the
Exchange Act. 
 (e) Number of Repurchased Shares. Counterparty represents that it could have purchased Shares, in an
amount equal to the product of the Number of Options and the Option Entitlement, on the Exchange or otherwise, in compliance with applicable law, its organizational documents and any orders, decrees, contractual agreements binding upon Counterparty,
on the Trade Date. 
 (f) Early Unwind. In the event the sale of Convertible Notes is not consummated with the initial
purchasers for any reason by the close of business in New York on November 13, 2006 (or such later date as agreed upon by the parties) (November 13, 2006 or such later date as agreed upon being the “Early Unwind Date”), this
Transaction shall automatically terminate (the “Early Unwind”), on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Counterparty under the Transaction shall be
cancelled and terminated and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and
to be performed in connection with the Transaction either prior to or after the Early Unwind Date; provided that, unless the sale of Convertible Bonds is not consummated with the initial purchasers for any reason other than as a result of
breach of the Purchase Agreement by the initial purchasers, Counterparty shall purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its affiliates and reimburse Dealer for any costs or expenses (including
market losses) relating to the unwinding of its 

  

 16 

 
Hedging Activities in connection with the Transaction (including any loss or cost incurred as a result of its terminating, liquidating, obtaining or reestablishing any
hedge or related trading position). The amount of any such reimbursement shall be determined by Dealer in its sole good faith discretion. Dealer shall notify Counterparty of such amount and Counterparty shall pay such amount in immediately available
funds on the Early Unwind Date. Dealer and Counterparty represent and acknowledge to the other that, subject to the proviso included in this paragraph, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and
finally discharged. 
 (g) Transfer or Assignment. Neither party may transfer any of its rights or obligations under the
Transaction without the prior written consent of the non-transferring party; provided that Dealer may transfer or assign without any consent of Counterparty its rights and obligations hereunder, in whole or in part, to any of its affiliates that are
not less creditworthy than Dealer (or that benefit from a guarantee issued by Jefferies Group, Inc.(“Jefferies Group”), or another affiliate not less creditworthy than Jefferies Group); provided further that at any time at which a
transaction proposed to be entered into by the Dealer would cause the Articles Ownership Percentage to exceed 4.9%, Dealer will (i) have a right to, unless Counterparty provides an acknowledgment to Dealer to the
effect that the Shares owned or controlled by Dealer or any of its affiliates will not be deemed as owned or controlled by an “Alien” (as defined in Article Twelve Section 6 of Counterparty’s Certificate of
Incorporation), or (ii) if requested by Counterparty, transfer or assign to a third party such portion of the Transaction that would otherwise cause the Articles Ownership Percentage to exceed 4.9% (it being understood and agreed that
Dealer would make such a transfer or assignment to (a) one of its U.S. affiliates, if, in Counterparty’s view, such a transfer or assignment would result in the Shares owned or controlled by such U.S. affiliates not being owned
or controlled by an “Alien” for purposes of Article Twelve of Counterparty’s Certificate of Incorporation) or (b) unless otherwise consented by Counterparty, to a third party who is not an “Alien” for purposes of
Article Twelve of Counterparty’s Certificate of Incorporation, if the transfer or assignment would otherwise result in the Shares owned or controlled by an “Alien” for purposes of Article Twelve of Counterparty’s Certificate of
Incorporation); provided further that if Dealer is unable to effect a transfer or assignment to a third party after its commercially reasonable efforts on pricing terms reasonably acceptable to Dealer (or to one of its U.S. affiliates, if,
in Counterparty’s view, such a transfer or assignment would result in the Shares owned or controlled by such U.S. affiliates not being owned or controlled by an “Alien” for purposes of Article Twelve of Counterparty’s
Articles of Incorporation) such that the Articles Ownership Percentage does not exceed 4.9%, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Articles Terminated
Portion”) of the Transaction, such that the Articles Ownership Percentage following such partial termination will be equal to 4.9%.
 Notwithstanding the foregoing, at any time at which the Option Equity Percentage exceeds 9.0%, if Dealer, in its discretion, is unable to effect a transfer or assignment to a third party after its commercially reasonable efforts on pricing
terms reasonably acceptable to Dealer such that the Option Equity Percentage is reduced to 9.0% or less, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Section 13 Terminated
Portion”) of the Transaction, such that the Option Equity Percentage following such partial termination will be equal to or less than 9.0%. 
 In the event that Dealer so designates an Early Termination Date with respect to an Articles Terminated Portion or a Section 13 Terminated Portion, a payment shall be made pursuant to Section 6 of the Agreement as if (i) an
Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the Articles Terminated Portion or the Section 13 Terminated Portion, as the case may be,
(ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii) such 

  

 17 

 
Transaction shall be the only Terminated Transaction (and, for the avoidance of doubt, the provisions of paragraph 9(k) shall apply to any amount that is payable by
Dealer to Counterparty pursuant to this sentence). 
 The “Articles Ownership Percentage” as of any day is the fraction, expressed as a
percentage, (A) the numerator of which is the number of Shares that Dealer and its affiliates “own or control” (within the meaning of Article 12 Section 2 of Counterparty’s Certificate of
Incorporation) on such day, and (B) the denominator of which is the number of Shares outstanding on such day. 
 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 Jefferies 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 Options and the Option Entitlement and (B) the denominator of which is the number of Shares outstanding on
such day. 
 (h) Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory
requirements, including any requirements relating to Dealer’s Hedging Activities hereunder, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be
delivered by Dealer on the Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a
“Staggered Settlement Date”) as follows: 
 (i) in such notice, Dealer will specify to Counterparty the related
Staggered Settlement Dates (provided that the last of such Staggered Settlement Dates shall occur not later than 20 Trading Days (as defined in the Indenture) following the Nominal Settlement Date) and the number of Shares that it will
deliver on each Staggered Settlement Date; 
 (ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on
all such Staggered Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; 
 (iii) if the Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Settlement terms will apply on each Staggered Settlement Date, except that the Shares to be delivered will be allocated among
such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause (i) above; 
 (iv) if Counterparty declares a dividend
or other distribution with respect to Shares with an ex dividend date falling on or after a Nominal Settlement Date and prior to a Staggered Settlement Date, then in addition to any Shares it delivers on such a Staggered Settlement Date, Dealer
shall deliver to Counterparty the amount of such dividend or other distribution in respect of such Shares on the Exchange Business Day next following its receipt of such dividend or distribution; and 
 (v) on each Staggered Settlement Date, Dealer shall deliver to Counterparty cash in an amount equal to the product of (1) 35 bps, (2) the number of days
from and including the Nominal Settlement Date to but excluding the Staggered Settlement Date, divided by 360, and (3) the product of the number of Shares delivered on such Staggered Settlement Date and the weighted average closing price of
Shares on each Trading Day from and including the Nominal Settlement Date to but excluding the Staggered Settlement Date. 
  

 18 

 (i) Role of Agent. Each party agrees and acknowledges that
(i) Jefferies & Company, Inc., an affiliate of Dealer (“Agent”), has acted solely as agent and not as principal with respect to this Transaction and (ii) Agent has no obligation or liability, by way of guaranty,
endorsement or otherwise, in any manner in respect of this 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 this Transaction. 
 (j) No Collateral or Setoff. Notwithstanding any
provision of the Agreement or any other agreement between the parties, the obligations of Dealer hereunder are not secured by any collateral. In addition to and without limiting any rights of set-off that a party hereto may have as a matter of law,
pursuant to contract or otherwise, upon the occurrence of an Early Termination Date, Dealer (and only Dealer) shall have the right to set off any obligation that it may have to Counterparty under this Confirmation, including without limitation any
obligation to make any payment of cash or delivery of Shares to Counterparty, against any obligation Counterparty may have to Dealer under any other agreement between Dealer and Counterparty relating to Shares (other than any warrant purchased by
Dealer from Counterparty during a three month period commencing on the Trade Date) (each such contract or agreement, a “Separate Agreement”), including without limitation any obligation to make a payment of cash or a delivery of
Shares or any other property or securities. For this purpose, Dealer shall be entitled to convert any obligation (or the relevant portion of such obligation) denominated in one currency into another currency at the rate of exchange at which it would
be able to purchase the relevant amount of such currency, and to convert any obligation to deliver any non-cash property into an obligation to deliver cash in an amount calculated by reference to the market value of such property as of the Early
Termination Date, as determined by the Calculation Agent in its sole discretion; provided that in the case of a set-off of any obligation to release or deliver assets against any right to receive fungible assets, such obligation and right
shall be set off in kind and; provided further that in determining the value of any obligation to deliver Shares, the value at any time of such obligation shall be determined by reference to the market value of the Shares at such time, as
determined in good faith by the Calculation Agent. If an obligation is unascertained at the time of any such set-off, the Calculation Agent may in good faith estimate the amount or value of such obligation, in which case set-off will be effected in
respect of that estimate, and the relevant party shall account to the other party at the time such obligation or right is ascertained. 
 (k) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If in respect of this Transaction, subject to paragraph (j) above, an amount is payable by Dealer to Counterparty
(i) pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or (ii) pursuant to Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Counterparty may request Dealer to satisfy any such
Payment Obligation by the Share Termination Alternative (as defined below) (except that Counterparty shall not make such an election in the event of a Nationalization, Insolvency or a Merger Event, in each case, in which the consideration to be paid
to holders of Shares consists solely of cash, or an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party, other than an Event of Default of the type described in
Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b)(i), (ii), (iii), (iv), (v) or (vi) of the Agreement in each case that resulted from an event or
events outside Counterparty’s control) and shall give irrevocable telephonic notice to Dealer, confirmed in writing within one Currency Business Day, no later than 12:00 p.m. New York local time on the Merger Date, the Announcement Date (in the
case of Nationalization or Insolvency), the Early Termination Date or date of cancellation, as applicable; provided that if Counterparty does not 

  

 19 

 
validly request Dealer to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its sole discretion, to satisfy its
Payment Obligation by the Share Termination Alternative, notwithstanding Counterparty’s election to the contrary. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement,
(1) separate amounts shall be calculated as set forth in Section 6(e) with respect to (i) this Transaction and (ii) all other Transactions, and (2) such separate amounts shall be payable pursuant to Section 6(d)(ii) of
the Agreement. 
  

			
	Share Termination Alternative:	 	Applicable, if elected as per above, and means that Dealer shall deliver to Counterparty the Share Termination Delivery Property on the date when the Payment Obligation would otherwise be due pursuant to
Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable (the “Share Termination Payment Date”), in satisfaction of the Payment Obligation in the manner reasonably requested by
Counterparty 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
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 and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation.
		
	Share Termination Delivery Unit:	 	One Share or, if a Merger Event has occurred and a corresponding adjustment to this Transaction has been made, 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 Merger Event, as determined by the Calculation Agent.
		
	Failure to Deliver:	 	Applicable

  

 20 

			
	Other applicable provisions:	 	If this Transaction is to be Share Termination Settled, 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
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.

 (l) 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 either 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. 
 (m) Registration.
Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to this Transaction cannot be sold in the public
market by Dealer without registration under the Securities Act of 1933, as amended (the “Securities Act”), Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered
offering, make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a
registered secondary offering; provided however, that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation
for the registered offering referred to above, then clause (ii) or clause (iii) of this Section shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a
private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance reasonably satisfactory to Dealer (in which case, the Calculation Agent shall
make any adjustments to the terms of this Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement), or
(iii) purchase the Hedge Shares from Dealer at the closing price on such Exchange Business Days, and in the amounts, requested by Dealer. 
 (n) Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax structure. 

(o) 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 Counterparty; 

  

 21 

 
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 Counterparty 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. 
 (p) Securities Contract; Swap Agreement. The parties hereto intend for: (a) the Transaction to be a “securities
contract” and a “swap agreement” as defined in the Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to be entitled to the protections afforded by, among other
Sections, Sections 362(b)(6), 362(b)(17), 555 and 560 of the Bankruptcy Code; (b) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect
to the other party to constitute a “contractual right” as described in the Bankruptcy Code; (c) any cash, securities or other property provided as performance assurance, credit support or collateral with respect to the Transaction to
constitute “margin payments” and “transfers” under a “swap agreement” as defined in the Bankruptcy Code; and (d) all payments for, under or in connection with the Transaction, all payments for the Shares and the
transfer of such Shares to constitute “settlement payments” and “transfers” under a “swap agreement” as defined in the Bankruptcy Code. 
 (q) Additional Provisions. Counterparty covenants and agrees that, as promptly as practicable following the public announcement of any
consolidation, merger and binding share exchange to which Counterparty is a party, or any sale of all or substantially all of Counterparty’s assets, in each case pursuant to which the Shares will be converted into cash, securities or other
property, Counterparty shall notify Dealer in writing of the types and amounts of consideration that holders of Shares have elected to receive upon consummation of such transaction or event (the date of such notification, the “Consideration
Notification Date”); provided that in no event shall the Consideration Notification Date be later than the date on which such transaction or event is consummated. 
 (r) Additional Termination Events. The occurrence of (i) an event of default with respect to Counterparty under the terms of the
Convertible Notes as set forth in Section 7.01 of the Indenture that results in an acceleration of the Convertible Notes pursuant to the terms of the Indenture, (ii) an Amendment Event or (iii) a PACC Termination Event (which shall be
deem to occur on the effective date for the related PACC Event) shall be an Additional Termination Event with respect to which the Transaction is the sole Affected Transaction and Counterparty is the sole Affected Party, and Dealer shall be the
party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. 
 “Amendment Event” means that
Counterparty amends, modifies, supplements or obtains a waiver in respect of any term of the Indenture or the Convertible Notes governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, redemption right of
Counterparty, any term relating to conversion of the Convertible Notes (including changes to the conversion price, conversion settlement dates or conversion conditions) that may adversely affect the rights or obligations of Dealer hereunder, or any
term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes to amend, in each case without the prior consent of Dealer, such consent not to be unreasonably withheld. 
 (s) “PACC Termination Event” means a PACC Event with respect to which (i) the Calculation Agent reasonably determines that no
PACC Adjustments would produce a commercially reasonable result, (ii) the PACC Adjustments have not been made because any of the documentation requirements set forth under “Consequences of Merger Events” above have not been satisfied
by the effective date for such PACC Event or (iii) Dealer has determined, in its reasonable discretion, that it will be unable to effect its hedge unwind, hedge leg in or other hedging activities in a manner compliant with applicable legal,
regulatory or self-regulatory requirements, or with policies and procedures applicable to Dealer related to such applicable legal, regulatory or self-regulatory requirements.

 Re: Call Option Transaction 
 The purpose
of this letter agreement is to confirm the terms and conditions of the Transaction entered into between Bear, Stearns International Limited (“Dealer”) and Hornbeck Offshore Services, Inc. (“Counterparty”) on the
Trade Date specified below (the “Transaction”). This letter agreement constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below. This Confirmation shall replace any previous agreements
and serve as the final documentation for this Transaction. 
 The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions
(the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation. In the event of any inconsistency between the Equity
Definitions and this Confirmation, this Confirmation shall govern. Certain defined terms used herein have the meanings assigned to them in the Offering Memorandum dated November 7, 2006 (the “Offering Memorandum”) relating to
the USD 220,000,000 principal amount of 1.625% Convertible Senior Notes due 2026, (the “Convertible Notes” and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by Counterparty
pursuant to an Indenture to be dated November 13, 2006 between Counterparty and Wells Fargo Bank, N.A., as trustee (without giving effect to any subsequent amendment, modification or waiver, the “Indenture”). In the event of
any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. 
 Each
party is hereby advised, and each such party acknowledges, that the other party has engaged in, or refrained from engaging in, substantial financial transactions and has taken other material actions in reliance upon the parties’ entry into the
Transaction to which this Confirmation relates on the terms and conditions set forth below. 
 1. This Confirmation evidences a complete and binding
agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation relates. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the
“Agreement”) as if Dealer and Counterparty had executed an agreement in such form (but without any Schedule except for (i) the election of the laws of the State of New York as the governing law, and (ii) the election of US
Dollars (“USD”) as the Termination Currency) on the Trade Date. In the event 

 
of any inconsistency between provisions of that Agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction to which this
Confirmation relates. The parties hereby agree that no Transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement. 
 2. The terms of the particular Transaction to which this Confirmation relates are as follows: 
 General Terms: 
  

			
	Trade Date:	 	November 8, 2006
		
	Option Style:	 	“Modified American”, as described under “Procedures for Exercise” below.
		
	Option Type:	 	Call
		
	Buyer:	 	Counterparty
		
	Seller:	 	Dealer
		
	Shares:	 	The common stock of Counterparty, par value USD 0.01 per Share (Exchange symbol “HOS”), subject to an adjustment as set forth under “Consequences of Merger Events”
below.
		
	Number of Options:	 	The product of (i) the Applicable Percentage and (ii) the number of Convertible Notes in denominations of USD 1,000 principal amount issued by Counterparty on the closing date for the initial issuance of
the Convertible Notes; provided that the Number of Options shall be automatically increased as of the date of exercise by Jefferies & Co., Inc. and Bear Stearns & Co. Inc., as representatives of the Initial Purchasers (as defined in
the Purchase Agreement), of their option pursuant to Section 1 of the Purchase Agreement dated as of November 7, 2006 between Counterparty, the guarantors named therein and the representatives of the Initial Purchasers party thereto (the
“Purchase Agreement”) by the product of (i) the Applicable Percentage and (ii) the number of Convertible Notes in denominations of USD 1,000 principal amount issued pursuant to such exercise (such Convertible Notes, the

including 5:00 PM (New York City time) on the Scheduled Trading Day immediately preceding the first day of the related Observation Period (as defined in the Indenture); provided that if by the 30th Scheduled Trading Day prior to November 15, 2013, Counterparty has specified November 15, 2013 as a redemption date for the Convertible Notes pursuant to the

 3 

			
		 	such redemption and the final day of the Exercise Period shall be the Scheduled Trading Day immediately preceding the redemption date; provided further that if by the 30th Scheduled Trading Day prior to November 15, 2013, Counterparty has not specified November 15, 2013 as a redemption date for the Convertible Notes
pursuant to the terms of the Indenture, notices of conversion received by Counterparty from holders of Convertible Notes following such 30th Scheduled Trading Day prior to November 15, 2013 shall not result in the commencement of an Exercise Period and no Exercisable Options will be exercised or deemed exercised in respect of such notices of conversion of

such Conversion Date).
		
	Exercisable Options:	 	In respect of each Exercise Period, a number of Options equal to the product of (i) the Applicable Percentage and (ii) the number of Relevant Convertible Notes surrendered to Counterparty for conversion

	Notice of Exercise:	 	Notwithstanding anything to the contrary in the

  

 4

Exercise of Options) shall be effective if given after the Notice Deadline but prior to 5:00 PM (New York City time) on the fifth Exchange Business Day of such “Observation Period,” in which event the Calculation Agent shall have the right
to adjust the Delivery Obligation as appropriate to reflect the additional costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer or any of its affiliates in connection with its hedging activities
(including the unwinding of any hedge position) as a result of its not having received such notice prior to the Notice Deadline, unless Counterparty’s chief financial officer received a phone call from an officer of the Dealer inquiring about
such notice between 9:00 AM and 5:00 PM (New York City time) on the second Exchange Business Day preceding the beginning of the Observation Period, in which case this proviso shall not apply; provided further that in respect of Exercisable

	Valuation Time:	 	At the close of trading of the regular trading session on the Exchange; provided that if the principal trading session is extended, the Calculation Agent shall determine the Valuation Time in
its reasonable discretion.
		
	Market Disruption Event:	 	Section 6.3(a) of the Equity Definitions is hereby amended by (x) deleting the phrase “during the one hour period that ends at the relevant Valuation Time” in Section 6.3(a)(ii) and replacing
it with the phrase “at any time prior to 1:00 p.m. on such Scheduled Trading Day of an aggregate one half hour period” and (y) deleting the phrase “or (iii) an Early Closure”.

 Settlement Terms: 
  

			
	Settlement Date:	 	In respect of an Exercise Date, the settlement date for the Shares and cash (in respect of fractional shares) to be delivered under the Relevant Convertible Notes under the terms of the Indenture;
provided that if such a day is not the third Currency Business Day following the last day of the related Observation Period, Dealer shall use its reasonable efforts to make deliveries on the Settlement Date for the Relevant Convertible Notes
(subject to receipt of a prior notice from Issuer sufficiently in advance of such Settlement Date) and if, notwithstanding such reasonable efforts, the Dealer is unable to effect the delivery on such day, then it shall be the third Currency Business
Day following the last day of the related Observation Period.
		
	Delivery Obligation:	 	In lieu of the obligations set forth in Sections 8.1 and 9.1 of the Equity Definitions, and subject to “Notice of Exercise” above, in respect of an Exercise Date occurring on or with respect
to a Conversion Date, Dealer will deliver to Counterparty, on the related Settlement Date, the product of (x) the Applicable Percentage and (y) an aggregate number of Shares and an aggregate amount of cash (in respect of fractional Shares) in excess
of (i) USD 1,000 (if Counterparty has elected to

  

 6 

			
		 	settle the Relevant Convertible Notes in cash and Shares) or (ii) the number of Shares equivalent to USD 1,000, as determined by the Calculation Agent based on the sum, for all Trading Days in the
Observation Period, of a respective number of Shares equal to USD 40 divided by the Daily VWAP (as defined in the Indenture) for each such Trading Day (if Counterparty has elected to settle the Relevant Convertible Notes in Shares only) that
Counterparty is obligated to deliver to the holder(s) of the Relevant Convertible Notes converted on such Conversion Date pursuant to Section 12.01(d) of the Indenture (the “Convertible Obligation”); provided that, if the
Relevant Convertible Notes are being converted in connection with any Fundamental Change (as defined in the Indenture), (a) the Calculation Agent shall determine an amount that would be payable by Dealer to Counterparty pursuant to Section
6(e)(ii)(1) of the Agreement (for purposes of such determination, the Calculation Agent shall not be taking into account the amount deliverable to the holder(s) of the Relevant Convertible Notes pursuant to Section 12.03 of the Indenture) if (x) the
Number of Options were equal to the product of the Applicable Percentage and the number of the Relevant Convertible Notes and (y) the Fundamental Change were an Additional Termination Event occurring on the effective date for the Fundamental Change
with Counterparty as the sole Affected Party (the “Fair Value Amount”), and (b) to the extent that a number of additional Shares that Counterparty is obligated to deliver to holder(s) of the Relevant Convertible Notes as a result of
any adjustments to the Conversion Rate pursuant to Section 12.03 of the Indenture in respect of such Fundamental Change exceeds the number of Shares equal to the Fair Value Amount (such number of Shares to be determined by the Calculation Agent
based on the daily VWAP of the Shares on the effective date of the Fundamental Change), then the “Delivery Obligation” shall be determined excluding any such excess Shares. For the avoidance of doubt, if the “Conversion
Obligation”, as defined in the Indenture, is less than or equal to USD 1,000 (or a number of Shares equivalent to USD 1,000 determined as set forth above), Dealer will have no delivery obligation hereunder.

  

 7 

			
	Notice of Delivery Obligation:	 	No later than the Exchange Business Day immediately following the last day of the “Observation Period”, as defined in the Indenture, Counterparty or the Trustee on behalf of Counterparty shall
give Dealer notice of the final number of Shares and the amount of cash (in respect of fractional shares) comprising the Convertible Obligation (it being understood, for the avoidance of doubt, that the requirement of Counterparty to deliver such
notice shall not limit Counterparty’s obligations with respect to Notice of Exercise, as set forth above, in any way).
		
	Other Applicable Provisions:	 	To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9, 9.11, 9.12 and 10.5 of the Equity Definitions will be applicable, except that all references in
such provisions to “Physical Settlement” shall be read as references to “Net Share Settlement”; and provided 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 Buyer is the Issuer of the Shares. “Net Share Settlement” in relation to any
Option means that Dealer is obligated to deliver Shares hereunder.
	
	 3. Additional Terms applicable to the Transaction:
  
 Adjustments applicable to the Transaction:
  

	Method of Adjustment:	 	Calculation Agent Adjustment, and means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any adjustment to the Conversion Rate of the Convertible Notes pursuant to the Indenture
(other than Section 12.03 of the Indenture, except to the extent provided under “Delivery Obligation” above), the Calculation Agent will make a corresponding adjustment to any one or more of the Number of Options, the Option Entitlement
and any other variable relevant to the exercise, settlement or payment for the Transaction. Immediately upon the occurrence of any adjustment contemplated in Section 12.03 of the Indenture (an “Adjustment Event”), Counterparty shall
notify the Calculation Agent of such Adjustment Event; and once the 

  

 8 

			
		 	adjustments to be made to the terms of the Indenture and the Convertible Notes in respect of such Adjustment Event have been determined, Counterparty shall immediately notify the Calculation Agent in
writing of the details of such adjustments.
		
	Potential Adjustment Events:	 	Notwithstanding Section 11.2(e) of the Equity Definitions, a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in Section 12.02 of the Indenture that
would result in an adjustment to the Conversion Rate of the Convertible Notes; provided that in no event shall there be any adjustment hereunder as a result of an adjustment to the Conversion Rate pursuant to Section 12.03 of the Indenture,
except to the extent provided under “Delivery Obligation” above.

 Extraordinary Events applicable to the Transaction: 
  

			
	Merger Events:	 	Notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in Section 12.05 of the Indenture.
		
	Tender Offers:	 	Notwithstanding Section 12.1(d) of the Equity Definitions, a “Tender Offer” means the occurrence of any event or condition set forth in Section 12.02(e) of the Indenture and, upon the occurrence
of such an event, adjustments set forth under “Method of Adjustment” above shall apply.
		
	Consequences of Merger Events:	 	Notwithstanding Section 12.2 of the Equity Definitions, upon the occurrence of a Merger Event, the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture
to any one or more of the nature of the Shares, Number of Options, the Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction; provided however that such adjustment shall be made without
regard to any adjustment to the Conversion Rate for the issuance of additional shares as set forth in Section 12.03 of the Indenture, except to the extent provided under “Delivery Obligation” above. Notwithstanding the

  

 9 

			
		 	foregoing, upon the occurrence of a Merger Event that constitutes a “Public Acquirer Change in Control”, as defined in the Indenture, with respect to which Counterparty elects to adjust the
terms of the Convertible Notes in accordance with Section 12.04 of the Indenture (such a Public Acquirer Change in Control, a “PACC Event”), subject to compliance with the proviso to this sentence, the Calculation Agent will adjust
any one or more of the nature of the Shares, the Number of Options, the Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction to the extent required to preserve the fair value of the
Transaction to Dealer (such adjustments, the “PACC Adjustments”); provided that, as a condition precedent to the adjustments contemplated above, Counterparty and, if Counterparty is not the issuer of the “Public Acquirer
Common Stock”, as defined in the Indenture, the issuer of the Public Acquirer Common Stock, shall, prior to the effective date of such PACC Event, have entered into such documentation containing representations, warranties and agreements
relating to securities laws and other issues as requested by Dealer that Dealer determined, in its reasonable discretion, to be reasonably necessary or appropriate to allow Dealer to continue as a party to the Transaction, as adjusted, and to
preserve its hedge unwind, hedge leg in and other hedging activities in connection with the Transaction in a manner compliant with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to
Dealer.
		
	Nationalization, Insolvency or Delisting:	 	Cancellation and Payment (Calculation Agent Determination); provided that Counterparty may elect settlement of the related obligation in accordance with Section 9(k) below; provided, further
that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not re-listed, re-traded or re-quoted within 30 Exchange
Business Days following such Delisting on a U.S. national or regional securities exchange or an established automated over-the-counter trading market in the U.S.; if the Shares are re-listed, re-traded or re-quoted within 30 Scheduled Trading Days
following

  

 10 

			
		 	such Delisting on any U.S. national or regional securities exchange or an established automated over-the-counter trading market in the U.S., such exchange or quotation system shall thereafter be deemed to
be the Exchange.

 (t) none of the Counterparty or any of its subsidiaries is in violation of its certificate of incorporation or
certificate of formation, or its bylaws or limited liability company agreement (or other organizational documents), or in default in the performance or observance of any material obligation, covenant or condition contained in any indenture,

Adverse Effect; and 
 (u) other than as set forth in the Offering Memorandum, there are no legal or governmental proceedings pending to
which the Counterparty or any of its subsidiaries is a party or of which any property of the Counterparty or any of its subsidiaries is the subject which, if determined adversely to the Counterparty or any of its subsidiaries, would individually or
in the aggregate have a Material Adverse Effect; and, to the best of the Counterparty’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

 15

Transaction, which it understands are not readily marketable, are not disproportionate to its net worth, and it is able to bear any loss in connection with the Transaction, including the loss of its entire investment in the Transaction, (ii) it
is an “accredited investor” as that term is defined in Regulation D as promulgated under the Securities Act, (iii) it is entering into the Transaction for its own account and without a view to the distribution or resale thereof,
(iv) the assignment, transfer or other disposition of the Transaction has not been and will not be registered under the Securities Act and is restricted under this Confirmation, the Securities Act and state securities laws, and (v) its
financial condition is such that it has no need for liquidity with respect to its investment in the Transaction and no need to dispose of any portion thereof to satisfy any existing or contemplated undertaking or indebtedness and is capable of
assessing the merits of and understanding (on its own behalf or through independent professional advice), and understands and accepts, the terms, conditions and risks of the Transaction. 
 9. Other Provisions:

Percentage as determined on such day is (i) greater than 4.5% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than
the Notice Percentage as of the date hereof). The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of which is the product of the Number of Options and the Option Entitlement and the
denominator of which is the number of Shares outstanding on such day.

hereof engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of any securities of Counterparty, other than a distribution meeting the requirements
of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Counterparty shall not, until the second Scheduled Trading Day immediately following the Trade Date, engage in any such distribution. 
 (d) No Manipulation. Counterparty is not entering into this Transaction to create actual or apparent trading activity in the Shares
(or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.

 (e) Number of Repurchased Shares. Counterparty represents that it could have purchased Shares, in an amount equal to
the product of the Number of Options and the Option Entitlement, on the Exchange or otherwise, in compliance with applicable law, its organizational documents and any orders, decrees, contractual agreements binding upon Counterparty, on the Trade
Date. 
 (f) Early Unwind. In the event the sale of Convertible Notes is not consummated with the initial purchasers for
any reason by the close of business in New York on November 13, 2006 (or such later date as agreed upon by the parties) (November 13, 2006 or such later date as 

  

 16 

 
agreed upon being the “Early Unwind Date”), this Transaction shall automatically terminate (the “Early Unwind”), on the Early Unwind
Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Counterparty under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from
and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date;
provided that, unless the sale of Convertible Bonds is not consummated with the initial purchasers for any reason other than as a result of breach of the Purchase Agreement by the initial purchasers, Counterparty shall purchase from Dealer on
the Early Unwind Date all Shares purchased by Dealer or one or more of its affiliates and reimburse Dealer for any costs or expenses (including market losses) relating to the unwinding of its Hedging Activities in connection with the Transaction
(including any loss or cost incurred as a result of its terminating, liquidating, obtaining or reestablishing any hedge or related trading position). The amount of any such reimbursement shall be determined by Dealer in its sole good faith
discretion. Dealer shall notify Counterparty of such amount and Counterparty shall pay such amount in immediately available funds on the Early Unwind Date. Dealer and Counterparty represent and acknowledge to the other that, subject to the proviso
included in this paragraph, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged. 
 (g) Transfer or Assignment. Neither party may transfer any of its rights or obligations under the Transaction without the prior written consent of the non-transferring party; provided that Dealer may transfer or
assign without any consent of Counterparty its rights and obligations hereunder, in whole or in part, to any of its affiliates that are not less creditworthy than Dealer (or that benefit from a guarantee issued by The Bear Stearns Companies Inc.
(“Bear Stearns”), or another affiliate not less creditworthy than Bear Stearns); provided further that at any time at which a transaction proposed to be entered into by Dealer would cause the Articles Ownership Percentage
to exceed 4.9%, Dealer will (i) have a right to, unless Counterparty provides an acknowledgment to Dealer to the effect that the Shares owned or controlled by Dealer or any of its affiliates will not be deemed as owned
or controlled by an “Alien” (as defined in Article Twelve Section 6 of Counterparty’s Certificate of Incorporation), or (ii) if requested by Counterparty, transfer or assign to a third party such portion of
the Transaction that would otherwise cause the Articles Ownership Percentage to exceed 4.9% (it being understood and agreed that Dealer would make such a transfer or assignment to (a) one of its U.S. affiliates, if, in
Counterparty’s view, such a transfer or assignment would result in the Shares owned or controlled by such U.S. affiliates not being owned or controlled by an “Alien” for purposes of Article Twelve of
Counterparty’s Certificate of Incorporation) or (b) unless otherwise consented by Counterparty, to a third party who is not an “Alien” for purposes of Article Twelve of Counterparty’s Certificate of Incorporation, if
the transfer or assignment would otherwise result in the Shares owned or controlled by an “Alien” for purposes of Article Twelve of Counterparty’s Certificate of Incorporation); provided further that if Dealer is unable to effect
a transfer or assignment to a third party after its commercially reasonable efforts on pricing terms reasonably acceptable to Dealer (or to one of its U.S. affiliates, if, in Counterparty’s view, such a transfer or assignment would result
in the Shares owned or controlled by such U.S. affiliates not being owned or controlled by an “Alien” for purposes of Article Twelve of Counterparty’s Articles of Incorporation) such that
the Articles Ownership Percentage does not exceed 4.9%, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Articles Terminated Portion”) of the
Transaction, such that the Articles Ownership Percentage following such partial termination will be equal to 4.9%.
 Notwithstanding the
foregoing, at any time at which the Option Equity Percentage exceeds 9.0%, if Dealer, in its discretion, is unable to effect a transfer or assignment to a third party after its commercially reasonable efforts on pricing terms reasonably acceptable
to Dealer such that the 

  

 17 

 
Option Equity Percentage is reduced to 9.0% or less, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the
“Section 13 Terminated Portion”) of the Transaction, such that the Option Equity Percentage following such partial termination will be equal to or less than 9.0%. 
 In the event that Dealer so designates an Early Termination Date with respect to an Articles Terminated Portion or a Section 13 Terminated Portion, a payment
shall be made pursuant to Section 6 of the Agreement as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the Articles Terminated
Portion or the Section 13 Terminated Portion, as the case may be, (ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii) such Transaction shall be the only Terminated Transaction (and,
for the avoidance of doubt, the provisions of paragraph 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence). 
 The “Articles Ownership Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and its affiliates “own or control” (within
the meaning of Article 12 Section 2 of Counterparty’s Certificate of Incorporation) on such day, and (B) the denominator of which is the number of Shares outstanding on such day. 
 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 Bear Stearns “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
Options and the Option Entitlement and (B) the denominator of which is the number of Shares outstanding on such day. 
 (h)
Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s Hedging Activities hereunder, Dealer reasonably determines that it would
not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on the Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a
“Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) as follows: 
 (i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (provided that the last of such Staggered
Settlement Dates shall occur not later than 20 Trading Days (as defined in the Indenture) following the Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date; 
 (ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number
of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; 
 (iii) if the Settlement terms set forth
above were to apply on the Nominal Settlement Date, then the Settlement terms will apply on each Staggered Settlement Date, except that the Shares to be delivered will be allocated among such Staggered Settlement Dates as specified by Dealer in the
notice referred to in clause (i) above; 
  

 18 

 (iv) if Counterparty declares a dividend or other distribution with respect to Shares with an ex dividend date
falling on or after a Nominal Settlement Date and prior to a Staggered Settlement Date, then in addition to any Shares it delivers on such a Staggered Settlement Date, Dealer shall deliver to Counterparty the amount of such dividend or other
distribution in respect of such Shares on the Exchange Business Day next following its receipt of such dividend or distribution; and 
 (v) on each
Staggered Settlement Date, Dealer shall deliver to Counterparty cash in an amount equal to the product of (1) 35 bps, (2) the number of days from and including the Nominal Settlement Date to but excluding the Staggered Settlement Date,
divided by 360, and (3) the product of the number of Shares delivered on such Staggered Settlement Date and the weighted average closing price of Shares on each Trading Day from and including the Nominal Settlement Date to but excluding the
Staggered Settlement Date. 
 (i) Role of Agent. Each party agrees and acknowledges that (i) Bear, Stearns &
Co. Inc., an affiliate of Dealer (“Agent”), has acted solely as agent and not as principal with respect to this Transaction and (ii) Agent has no obligation or liability, by way of guaranty, endorsement or otherwise, in any
manner in respect of this 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 this Transaction. 
 (j) No Collateral or Setoff. Notwithstanding any provision of the Agreement or any
other agreement between the parties, the obligations of Dealer hereunder are not secured by any collateral. In addition to and without limiting any rights of set-off that a party hereto may have as a matter of law, pursuant to contract or otherwise,
upon the occurrence of an Early Termination Date, Dealer (and only Dealer) shall have the right to set off any obligation that it may have to Counterparty under this Confirmation, including without limitation any obligation to make any payment of
cash or delivery of Shares to Counterparty, against any obligation Counterparty may have to Dealer under any other agreement between Dealer and Counterparty relating to Shares (other than any warrant purchased by Dealer from Counterparty during a
three month period commencing on the Trade Date) (each such contract or agreement, a “Separate Agreement”), including without limitation any obligation to make a payment of cash or a delivery of Shares or any other property or
securities. For this purpose, Dealer shall be entitled to convert any obligation (or the relevant portion of such obligation) denominated in one currency into another currency at the rate of exchange at which it would be able to purchase the
relevant amount of such currency, and to convert any obligation to deliver any non-cash property into an obligation to deliver cash in an amount calculated by reference to the market value of such property as of the Early Termination Date, as
determined by the Calculation Agent in its sole discretion; provided that in the case of a set-off of any obligation to release or deliver assets against any right to receive fungible assets, such obligation and right shall be set off in kind
and; provided further that in determining the value of any obligation to deliver Shares, the value at any time of such obligation shall be determined by reference to the market value of the Shares at such time, as determined in good faith by
the Calculation Agent. If an obligation is unascertained at the time of any such set-off, the Calculation Agent may in good faith estimate the amount or value of such obligation, in which case set-off will be effected in respect of that estimate,
and the relevant party shall account to the other party at the time such obligation or right is ascertained. 
 (k) Alternative
Calculations and Payment on Early Termination and on Certain Extraordinary Events. If in respect of this Transaction, subject to paragraph (j) above, an amount is payable by Dealer to Counterparty (i) pursuant to Section 12.7
or Section 12.9 of the Equity Definitions or (ii) pursuant to Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Counterparty may request Dealer to satisfy any such Payment Obligation by the Share Termination
Alternative (as defined below) (except that Counterparty shall not make such an election in the event of a Nationalization, Insolvency or a Merger Event, in each case, in which the 

  

 19 

 
consideration to be paid to holders of Shares consists solely of cash, or an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in
which Counterparty is the Affected Party, other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b)(i),
(ii), (iii), (iv), (v) or (vi) of the Agreement in each case that resulted from an event or events outside Counterparty’s control) and shall give irrevocable telephonic notice to Dealer, confirmed in writing within one Currency
Business Day, no later than 12:00 p.m. New York local time on the Merger Date, the Announcement Date (in the case of Nationalization or Insolvency), the Early Termination Date or date of cancellation, as applicable; provided that if
Counterparty does not validly request Dealer to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its sole discretion, to satisfy its Payment Obligation by the Share Termination Alternative,
notwithstanding Counterparty’s election to the contrary. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement, (1) separate amounts shall be calculated as set forth
in Section 6(e) with respect to (i) this Transaction and (ii) all other Transactions, and (2) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement. 
  

			
	Share Termination Alternative:	 	Applicable, if elected as per above, and means that Dealer shall deliver to Counterparty the Share Termination Delivery Property on the date when the Payment Obligation would otherwise be due pursuant to
Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable (the “Share Termination Payment Date”), in satisfaction of the Payment Obligation in the manner reasonably requested by
Counterparty 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
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 and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation.
		
	Share Termination Delivery Unit:	 	One Share or, if a Merger Event has occurred and a corresponding adjustment to this Transaction has been made, a unit consisting of

  

 20 

			
		 	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 Merger Event, as determined by the Calculation Agent.
		
	Failure to Deliver:	 	Applicable
		
	Other applicable provisions:	 	If this Transaction is to be Share Termination Settled, 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
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.

 (l) 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 either 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. 
 (m) Registration.
Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to this Transaction cannot be sold in the public
market by Dealer without registration under the Securities Act of 1933, as amended (the “Securities Act”), Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered
offering, make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a
registered secondary offering; provided however, that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation
for the registered offering referred to above, then clause (ii) or clause (iii) of this Section shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a
private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance reasonably satisfactory to Dealer (in which case, the Calculation Agent shall
make any adjustments to the terms of this Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement), or
(iii) purchase the Hedge Shares from Dealer at the closing price on such Exchange Business Days, and in the amounts, requested by Dealer. 
  

 21 

 (n) Tax Disclosure. Effective from the date of commencement of discussions concerning
the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind
(including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax structure. 
 (o)
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 Counterparty; 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 Counterparty 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. 
 (p) Securities Contract; Swap Agreement. The parties hereto intend for: (a) the Transaction to be a “securities
contract” and a “swap agreement” as defined in the Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to be entitled to the protections afforded by, among other
Sections, Sections 362(b)(6), 362(b)(17), 555 and 560 of the Bankruptcy Code; (b) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect
to the other party to constitute a “contractual right” as described in the Bankruptcy Code; (c) any cash, securities or other property provided as performance assurance, credit support or collateral with respect to the Transaction to
constitute “margin payments” and “transfers” under a “swap agreement” as defined in the Bankruptcy Code; and (d) all payments for, under or in connection with the Transaction, all payments for the Shares and the
transfer of such Shares to constitute “settlement payments” and “transfers” under a “swap agreement” as defined in the Bankruptcy Code. 
 (q) Additional Provisions. Counterparty covenants and agrees that, as promptly as practicable following the public announcement of any
consolidation, merger and binding share exchange to which Counterparty is a party, or any sale of all or substantially all of Counterparty’s assets, in each case pursuant to which the Shares will be converted into cash, securities or other
property, Counterparty shall notify Dealer in writing of the types and amounts of consideration that holders of Shares have elected to receive upon consummation of such transaction or event (the date of such notification, the “Consideration
Notification Date”); provided that in no event shall the Consideration Notification Date be later than the date on which such transaction or event is consummated. 
 (r) Additional Termination Events. The occurrence of (i) an event of default with respect to Counterparty under the terms of the
Convertible Notes as set forth in Section 7.01 of the Indenture that results in an acceleration of the Convertible Notes pursuant to the terms of the Indenture, (ii) an Amendment Event or (iii) a PACC Termination Event (which shall be
deem to occur on the effective date for the related PACC Event) shall be an Additional Termination Event with respect to which the Transaction is the sole Affected Transaction and Counterparty is the sole Affected Party, and Dealer shall be the
party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. 
 “Amendment Event” means that
Counterparty amends, modifies, supplements or obtains a waiver in respect of any term of the Indenture or the Convertible Notes governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, redemption right of
Counterparty, any term relating to conversion of the Convertible Notes (including changes to the conversion price, conversion settlement dates or conversion conditions) that may adversely affect the rights or obligations of Dealer hereunder, or any
term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes to amend, in each case without the prior consent of Dealer, such consent not to be unreasonably withheld. 
  

 22 

 (s) “PACC Termination Event” means a PACC Event with respect to which (i) the
Calculation Agent reasonably determines that no PACC Adjustments would produce a commercially reasonable result, (ii) the PACC Adjustments have not been made because any of the documentation requirements set forth under “Consequences of
Merger Events” above have not been satisfied by the effective date for such PACC Event or (iii) Dealer has determined, in its reasonable discretion, that it will be unable to effect its hedge unwind, hedge leg in or other hedging
activities in a manner compliant with applicable legal, regulatory or self-regulatory requirements, or with policies and procedures applicable to Dealer related to such applicable legal, regulatory or self-regulatory requirements.
