EXECUTION VERSION

Dear Sir(s):

The purpose of this communication (this “Confirmation”) is to set forth the terms and conditions of the above-referenced transaction entered into on the Trade Date specified below (the “Transaction”) between Credit Suisse Capital LLC (“Dealer”), represented by Credit Suisse Securities (USA) LLC (“Agent”) as its agent, and Bristow Group Inc. (“Counterparty”). This communication constitutes a “Confirmation” as referred to in the Agreement specified below.

1. This Confirmation is subject to, and incorporates, the definitions and provisions of the 2000 ISDA Definitions (including the Annex thereto) (the “2000 Definitions”) and the definitions and provisions of the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”, and together with the 2000 Definitions, the “Definitions”), in each case as published by the International Swaps and Derivatives Association, Inc. (“ISDA”). In the event of any inconsistency between the 2000 Definitions and the Equity Definitions, the Equity Definitions will govern. Certain defined terms used herein have the meanings assigned to them in the Base Indenture dated as of June 17, 2008 among Counterparty, the potential subsidiary guarantors party thereto and U.S. Bank National Association, as trustee (the “Base Indenture”), as supplemented by the Sixth Supplemental Indenture to be dated as of December 18, 2017 among Counterparty, the subsidiary guarantors party thereto and U.S. Bank National Association, as trustee (the “Supplemental Indenture,” and the Base Indenture as so supplemented, the “Indenture”), relating to USD125,000,000 principal amount of Counterparty’s 4.50% convertible senior notes due 2023 (the “Convertible Notes”) (as increased by an aggregate principal amount of USD18,750,000 of Convertible Notes pursuant to the exercise by the Underwriters (as defined herein) of their option to purchase additional Convertible Notes pursuant to the Underwriting Agreement (as defined herein)). In the event of any inconsistency between the terms defined in the Indenture and this Confirmation, this Confirmation shall govern. References herein to sections of the Supplemental Indenture are based on the draft of the Supplemental Indenture most recently reviewed by the parties at the time of execution of this Confirmation. If any relevant sections of the Supplemental Indenture are changed, added or renumbered between the execution of this Confirmation and the execution of the Supplemental Indenture, the parties will amend this Confirmation in good faith to preserve the economic intent of the parties based on the draft of the Indenture so reviewed. The parties further acknowledge that references to the Base Indenture or Supplemental

1

Indenture herein are references to the Base Indenture or the Supplemental Indenture, as the case may be, as in effect on the date hereof and on the date of its execution, respectively, and if either the Base Indenture or the Supplemental Indenture is amended following its execution (other than any amendment pursuant to (x) Section 6.01(i) of the Supplemental Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the prospectus supplement and issuer free writing prospectus related to the offering of the Convertible Notes or (y) Section 8.06(a) of the Supplemental Indenture, subject, in the case of this clause (y), to the second paragraph under “Method of Adjustment” in Section 2), any such amendment will be disregarded for purposes of this Confirmation unless the parties agree otherwise in writing. The Transaction is subject to Early Unwind if the closing of the Convertible Notes is not consummated for any reason, as set forth below in Section 8(j).

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.

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 be subject to an agreement (the “Agreement”) in the form of the 2002 ISDA Master Agreement, as published by ISDA, as if Dealer and Counterparty had executed an agreement in such form on the date hereof (but without any Schedule except for (i) the election of US Dollars (“USD”) as the Termination Currency and (ii) the elections that (a) the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Dealer with a “Threshold Amount” of three percent of the shareholders’ equity of Dealer or Dealer’s ultimate parent as of the Trade Date, (b) the phrase “or becoming capable at such time of being declared” shall be deleted from clause (1) of such Section 5(a)(vi), (c) the following language shall be added to the end thereof: “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (x) the default was caused solely by error or omission of an administrative or operational nature; (y) funds were available to enable the party to make the payment when due; and (z) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay.”, and (d) the term “Specified Indebtedness” shall have the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in respect of deposits received in the ordinary course of a party’s banking business).

13

(ii) On the Trade Date and the Premium Payment Date, neither Counterparty nor any “affiliate” or “affiliated purchaser” (each as defined in Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall directly or indirectly (including, without limitation, by means of any cash-settled or other derivative instrument other than the Transaction) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or commence any tender offer relating to, any Shares (or an equivalent interest, including a unit of beneficial interest in a trust or limited partnership or a depository share) or any security convertible into or exchangeable or exercisable for Shares.

(iii) Without limiting the generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that Dealer is not making any representations or warranties or taking any position or expressing any view with respect to the treatment of the Transaction under any accounting standards including ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, or ASC Topic 480, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity (or any successor issue statements) or under FASB’s Liabilities & Equity Project.

(v) On or prior to the Trade Date, Counterparty shall deliver to Dealer a resolution of Counterparty’s board of directors authorizing the Transaction.

(vi) Counterparty is not entering into this Confirmation to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for Shares) or to otherwise violate the Exchange Act.

(vii) Counterparty is not, and after giving effect to the transactions contemplated hereby will not be, required to register as an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended.

(viii) On the Trade Date and the Premium Payment Date, Counterparty is not “insolvent” (as such term is defined under Section 101(32) of the U.S. Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”)) and Counterparty would be able to purchase the Number of Shares hereunder in compliance with the laws of the jurisdiction of Counterparty’s incorporation or organization, as applicable.

(ix) The representations and warranties of Counterparty set forth in Section 3 of the Agreement and Section 2 of the Underwriting Agreement dated as of December 13, 2017 between Counterparty and Credit Suisse Securities (USA) LLC, Barclays Capital Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives of the Underwriters party thereto (the “Underwriting Agreement”), are true and correct as of the Trade Date and the Premium Payment Date and are hereby deemed to be repeated to Dealer as if set forth herein.

(xi) Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million.

14

(c) 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(a)(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.

(d) Each of Dealer and Counterparty agrees and acknowledges that Dealer is a “financial institution,” “swap participant” and “financial participant” within the meaning of Sections 101(22), 101(53C) and 101(22A) of Title 11 of the United States Code (the “Bankruptcy Code”). The parties hereto further agree and acknowledge (A) that this Confirmation is (i) 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 is a “settlement payment,” as such term is defined in Section 741(8) of the Bankruptcy Code, and (ii) a “swap agreement,” as such term is defined in Section 101(53B) of the Bankruptcy Code, with respect to which each payment and delivery hereunder is a “transfer,” as such term is defined in Section 101(54) of the Bankruptcy Code, and (B) that Dealer is entitled to the protections afforded by, among other sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code.

(e) Counterparty shall deliver to Dealer one or more opinions of counsel, dated as of the Effective Date and reasonably acceptable to Dealer in form and substance, with respect to the matters set forth in Sections 3(a)(i), (ii), (iii) and (iv) of the Agreement; provided that any such opinion of counsel may contain customary exceptions and qualifications, including, without limitation, exceptions and qualifications relating to indemnification provisions.

(f) Each party acknowledges and agrees to be bound by the Conduct Rules of the Financial Industry Regulatory Authority applicable to transactions in options, and further agrees not to violate the position and exercise limits set forth therein.

8. Other Provisions:

(a) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that is within Counterparty’s control, or (iii) 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) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one

15

Scheduled Trading Day, no later than 12:00 p.m. (New York City 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, of its election that the Share Termination Alternative shall not apply, (b) Counterparty remakes the representation set forth in Section 7(a)(i) as of the date of such election and (c) Dealer agrees, in its sole discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.

(b) Disposition of Hedge Shares. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, based on advice of counsel, the Shares (the “Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction cannot be sold in the U.S. public market by Dealer without registration under the Securities Act, Counterparty shall, at its election: (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 to cover the resale of such Hedge Shares and (A)

16

enter into an agreement, in form and substance satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered offering of similar size, (B) provide accountant’s “comfort” letters in customary form for registered offerings of equity securities of similar size, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities of similar size and (E) afford Dealer a reasonable opportunity to conduct a “due diligence” investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities of similar size; 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 8(b) shall apply at the election of Counterparty; (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, to enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities of similar size, in form and substance reasonably satisfactory to Dealer, including 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 Hedge Shares from Dealer), opinions and certificates and such other documentation as is customary for private placements agreements for private placements of equity securities of similar size, all reasonably acceptable to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its commercially reasonable judgment, to compensate Dealer for any commercially reasonable 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 VWAP Price on such Exchange Business Days, and in the amounts, requested by Dealer. “VWAP Price” means, on any Exchange Business Day, the per Share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page BRS <equity> VAP (or any successor thereto) in respect of the period from 9:30 a.m. to 4:00 p.m. (New York City time) on such Exchange Business Day (or if such volume-weighted average price is unavailable, the market value of one Share on such Exchange Business Day, as determined by the Calculation Agent using a volume-weighted method). This Section 8(b) shall survive the termination, expiration or Early Unwind of the Transaction.

(c) Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if, following such repurchase, the Notice Percentage as determined on such day is (i) greater than 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 Number of Shares plus the number of Shares underlying any other call options sold by Dealer to Counterparty and the denominator of which is the number of Shares outstanding on such day. In the event that Counterparty fails to provide Dealer with a Repurchase Notice on the day and in the manner specified in this Section 8(c) then Counterparty agrees to indemnify and hold harmless Dealer, its affiliates and their respective directors, officers, employees, agents and controlling persons (Dealer and each such person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable securities laws, including without limitation, Section 16 of the Exchange Act, relating to or arising out of such failure. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability. In addition, Counterparty will reimburse any Indemnified Party for all expenses (including reasonable counsel fees and expenses) as they are incurred (after notice to Counterparty) in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. This indemnity shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and delegation of the Transaction made pursuant to this Confirmation or the Agreement shall inure to the benefit of any permitted assignee of Dealer.

17

(d) 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 4.01 of the Supplemental Indenture or Section 6.01 of the “Original Indenture” (as such term is defined in the Supplemental Indenture) that results in the Convertible Notes becoming or being declared due and payable pursuant to the terms of the Supplemental Indenture or (ii) a Repurchase Event, shall be an Additional Termination Event with respect to which, in the case of clause (i) of this Section 8(d), the Transaction is the sole Affected Transaction, and in the case of clause (ii) of this Section 8(d), the relevant Repayment Terminated Portion of the Transaction is the sole Affected Transaction, and in both cases, Counterparty is the sole Affected Party, and Dealer shall be the sole party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement (which Early Termination Date shall be on or as promptly as commercially reasonably practicable after the occurrence of the related acceleration or Repurchase Event). On any Early Termination Date relating to any Repurchase Event, the Number of Options shall be reduced by the number of Repurchase Options in respect of such Repurchase Event.

“Repurchase Event” means that (i) any Convertible Notes are repurchased for any reason by Counterparty or any of its subsidiaries, (ii) any Convertible Notes are delivered to Counterparty in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (iii) any principal of any of the Convertible Notes is repaid prior to the final maturity date of the Convertible Notes (whether following acceleration of the Convertible Notes or otherwise), or (iv) any Convertible Notes are exchanged by or for the benefit of the holders thereof for any other securities of Counterparty or any of its affiliates (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction. For the avoidance of doubt, any conversion of Convertible Notes pursuant to the terms of the Indenture shall not constitute a Repurchase Event.

“Repurchase Terminated Portion” means, in respect of any Repurchase Event, a portion of the Transaction consisting of a number of Options (the “Repurchase Options”) equal to the lesser of (A) the number of Convertible Notes in denominations of USD1,000 that are subject to the relevant Repurchase Event (the “Repurchase Convertible Notes”) (and for the purposes of determining whether any Convertible Notes will be Repurchase Convertible Notes hereunder or under, and as defined in, the Base Convertible Bond Hedge Transaction Confirmation, Convertible Notes that are subject to a Repurchase Event shall be allocated first to the Base Convertible Bond Hedge Transaction Confirmation until all Options thereunder are exercised or terminated) and (B) the Number of Options as of the date Dealer designates such Early Termination Date.

(e) Right to Extend. Dealer may postpone any Settlement Date or any other date of valuation or delivery by Dealer, with respect to some or all of the relevant Options (in which event the Calculation Agent shall make appropriate adjustments to the Delivery Obligation to reflect such postponement), if Dealer determines, in its good faith reasonable discretion based on advice of counsel, that such extension is reasonably necessary or appropriate to preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer, provided that such policies and procedures have been adopted by Dealer in good faith and are generally applicable in similar situations and applied in a non-discriminatory manner.

(f) 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 advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on one or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows:

(i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or prior to such Nominal Settlement Date, but not prior to the relevant Conversion Date) or delivery times and how it will allocate the Shares it is required to deliver under “Delivery Obligation” (above) among the Staggered Settlement Dates or delivery times; and

18

(ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date.

(g) Transfer and Assignment. Either party may transfer or assign any of its rights or obligations under the Transaction with the prior written consent of the non-transferring party, such consent not to be unreasonably withheld or delayed. For the avoidance of doubt, Dealer may condition its consent on any of the following, without limitation: (i) the receipt by Dealer of opinions and documents reasonably satisfactory to Dealer in connection with such assignment, (ii) such assignment being effected on terms reasonably satisfactory to Dealer with respect to any legal and regulatory requirements relevant to Dealer, (iii) Counterparty or the Issuer, as applicable, continuing to be obligated to provide notices hereunder relating to the Convertible Notes and continuing to be obligated with respect to “Disposition of Hedge Shares” and “Repurchase Notices” above, (iv) payment by Counterparty of all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such assignment, (v) Dealer not being obliged, as a result of such assignment, to pay the assignee on any payment date, an amount greater than Dealer would have been required to pay in the absence of such assignment and (vi) no Event of Default, Potential Event of Default or Termination Event occurring as a result of such assignment. In addition, 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 whose credit quality is equivalent to or better than Dealer’s or whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer (or Dealer’s ultimate parent entity, as applicable) generally for similar transactions by Dealer or Dealer’s ultimate parent entity. After a transfer or assignment by Dealer described in this paragraph, the transferee or assignee shall agree (1) Counterparty will not be required to pay the transferee or assignee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Counterparty would have been required to pay to Dealer in the absence of such transfer or assignment; and (2) Counterparty will not, as a result of such transfer or assignment, receive from the transferee or assignee on any payment date an amount that, after taking into account amounts owed by the transferee or assignee to Counterparty and any taxes withheld under Section 2(d)(i)(4) of the Agreement, is less than the amount that Counterparty would have received from Dealer in the absence of such transfer or assignment. In addition, Dealer will not transfer or assign any of its rights or obligations under the Transaction to the extent such transfer or assignment causes a deemed exchange for Counterparty of the Transaction under Section 1001 of the Internal Revenue Code of 1986, as amended (the “Code”).

At any time at which (1) the Equity Percentage exceeds 8.5% or (2) 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 state or federal bank holding company or banking laws, or other federal, state or local regulations or regulatory orders or any organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), 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 would give rise to reporting or registration obligations (except for any filings of Form 13F, Schedule 13D or Schedule 13G under the Exchange Act) or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person under Applicable Restrictions 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 (either such condition described in clause (1) or (2), an “Excess Ownership Position”), if Dealer, in its discretion, is unable to effect a transfer or assignment to a third party in accordance with the requirements set forth above after using its commercially reasonable efforts on pricing terms reasonably acceptable to Dealer such that an Excess Ownership Position no longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of the Transaction, such that such Excess Ownership Position no longer exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment or delivery shall be made pursuant to Section 6 of the Agreement and Section 8(a) of this Confirmation as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Terminated Portion of the Transaction, (ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii) such portion of the Transaction shall be the only Terminated Transaction. The “Equity

19

Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer or any affiliate of Dealer subject to aggregation with Dealer under Section 13 of the Exchange Act and the rules promulgated thereunder or any “group”, as such term is used in such Section 13 and rules, of which Dealer or any such affiliate of Dealer is a member or may be deemed to be a member (collectively, “Dealer Group”) “beneficially own” (within the meaning of such Section 13 and such rules) without duplication on such day and (B) the denominator of which is the number of Shares outstanding on such day.

(h) Equity Rights. Dealer acknowledges and agrees that this Confirmation is not intended to convey to it rights with respect to the Transaction that are senior to the claims of common stockholders in the event of Counterparty’s bankruptcy. For the avoidance of doubt, the parties agree that the preceding sentence shall not apply at any time other than during Counterparty’s bankruptcy to any claim arising as a result of a breach by Counterparty of any of its obligations under this Confirmation or the Agreement. For the avoidance of doubt, the parties acknowledge that this Confirmation is not secured by any collateral that would otherwise secure the obligations of Counterparty herein under or pursuant to any other agreement.

(i) No Netting or Set-off. The provisions of Section 2(c) of the Agreement shall not apply to the Transaction.
