The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the call option transaction entered into between Wachovia Bank, National Association (“Dealer”), represented by Wachovia Capital Markets, LLC (“Agent”) as its agent, and Exterran Holdings, Inc. (“Counterparty”) as of 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 Prospectus dated June 3, 2009, as supplemented by the Prospectus Supplement dated June 4, 2009 (as so supplemented, the “Prospectus”) relating to the USD 325,000,000 principal amount of 4.25% Convertible Senior Notes due 2014 (the “Convertible Notes” and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by Counterparty pursuant to the Indenture to be dated as of June 10, 2009 (the “Base Indenture”), as supplemented by a Supplemental Indenture thereto (the “Supplemental Indenture”) to be dated June 10, 2009, between Counterparty and Xxxxx Fargo Bank, National Association, as trustee (the Base Indenture as so supplemented, the “Indenture”). In the event of any inconsistency between the terms defined in the Prospectus, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Prospectus. If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Prospectus, the descriptions thereof in the Prospectus will govern for purposes of this Confirmation. The parties further acknowledge that the Indenture section numbers used herein are based on the draft of the Indenture last reviewed by Dealer as of the date of this Confirmation, and if any such section numbers are changed in the Indenture as executed, the parties will amend this Confirmation in good faith to preserve the intent of the parties. For the avoidance of doubt, references to the Base Indenture or Supplemental Indenture, as the case may be, herein are references to the Base Indenture or the Supplemental Indenture, as the case may be, as in effect on the date of its execution and if the Base Indenture or the Supplemental Indenture is amended following such date, any such amendment will be disregarded for purposes of this Confirmation unless the parties agree otherwise in writing.

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.

Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to this Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of this Transaction.
	(c)		Regulation M. Counterparty is not on the date hereof engaged in a distribution, as such term is used in Regulation M under the Exchange Act, of any securities of Counterparty, other than the distribution of the Convertible Notes. Counterparty shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.

13

	(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)		Transfer or Assignment. (i) Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”); provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to the following conditions:

(A) With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 9(b) or any obligations under Section 9(m) or 9(r) of this Confirmation;

(B) Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended);

(C) Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty, as are requested and reasonably satisfactory to Dealer;

(D) Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment;

(E) An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment;

(F) Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

(G) Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

(ii) Dealer may, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any third party with a rating for its long term, unsecured and unsubordinated indebtedness equal to or better than the lesser of (x) the credit rating of Dealer at the time of the transfer and (y) A- by Standard and Poor’s Rating Group, Inc. or its successor (“S&P”), or A3 by Xxxxx’x Investor Service, Inc. (“Moody’s”) or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer. If at any time at which (1) the Section 16 Percentage exceeds 7.5%, (2) the Option Equity Percentage exceeds 14.5%, or (3) the Share Amount exceeds the Post-Effective Limit (if any applies), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that (1) the Section 16 Percentage will be equal to or less than 7.5%, (2) the Option Equity Percentage will be equal to or less than 14.5%, and (3) the Share Amount will be equal to or less than any such Post-Effective Limit, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination (1) the Section 16 Percentage will be equal to or less than 7.5%, (2) the Option Equity Percentage will be equal to or less than 14.5%, and (3) the Share Amount

14

will be equal to or less than such Post-Effective Limit. In the event that Dealer so designates an Early Termination Date with respect to a Terminated Portion, a payment shall be made pursuant to Section 6 of the Agreement as if (1) 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 number of Options underlying the Terminated Portion, (2) Counterparty shall be the sole Affected Party with respect to such partial termination and (3) the Terminated Portion shall be the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “Section 16 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 each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (x) the product of the Number of Options and the Option Entitlement and (y) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation or regulatory order that for any reason becomes applicable to ownership of Shares after the Trade Date (“Applicable Laws”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership of under the Applicable Laws, as determined by Dealer in its reasonable discretion. The “Post-Effective Limit” means (x) the minimum number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or would result in an adverse effect on a Dealer Person, under the Applicable Laws, as determined by Dealer in its reasonable discretion, minus (y) 1% of the number of Shares outstanding.

(iii) Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Dealer’s obligations in respect of this Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

	(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 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 (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th) Exchange Business Day following such 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; and
			(iii) if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as applicable, will apply on each Staggered Settlement Date, except that the Shares deliverable pursuant to such terms on the Nominal Settlement Date will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause (i) above.

15

	(g)		Role of Agent.
			(i) The Agent is registered as a broker-dealer with the U.S. Securities and Exchange Commission and the National Association of Securities Dealers, is acting hereunder for and on behalf of Dealer solely in its capacity as agent for Dealer pursuant to instructions from Dealer, and is not and will not be acting as Counterparty’s agent, broker, advisor or fiduciary in any respect under or in connection with this Transaction.
			(ii) In addition to acting as Dealer’s agent in executing this Transaction, the Agent is authorized from time to time to give written payment and/or delivery instructions to Counterparty directing it to make its payments and/or deliveries under this Transaction to an account of the Agent for remittance to Dealer (or its designee), and for that purpose any such payment or delivery by Counterparty to the Agent shall be treated as a payment or delivery to Dealer.
			(iii) Except as otherwise provided herein, any and all notices, demands, or communications of any kind transmitted in writing by either Dealer or Counterparty under or in connection with this Transaction will be transmitted exclusively by such Party to the other Party through the Agent at the following address:
			Wachovia Capital Markets, LLC 000 Xxxxx Xxxxxxx Xxxxxx, 0xx Xxxxx Xxxxxxxxx, XX 00000-0000 Facsimile No.: (000) 000-0000 Telephone No.: (000) 000-0000 Attention: Equity Derivatives
			(iv) The Agent shall have no responsibility or liability to Dealer or Counterparty for or arising from (A) any failure by either Dealer or Counterparty to perform any of their respective obligations under or in connection with this Transaction, (B) the collection or enforcement of any such obligations, or (C) the exercise of any of the rights and remedies of either Dealer or Counterparty under or in connection with this Transaction. Each of Dealer and Counterparty agrees to proceed solely against the other to collect or enforce any such obligations, and the Agent shall have no liability in respect of this Transaction except for its gross negligence or willful misconduct in performing its duties as the agent of Dealer.
			(v) Upon written request, the Agent will furnish to Dealer and Counterparty the date and time of the execution of this Transaction and a statement as to the source and amount of any remuneration received or to be received by the Agent in connection with this Transaction.
	(h)		Additional Termination Events. Notwithstanding anything to the contrary in this Confirmation if an event of default with respect to Counterparty shall occur under the terms of the Convertible Notes as set forth in Section 5.01 of the Supplemental Indenture or under Section 6.01 of the Base Indenture, as modified by Section 5.01 of the Supplemental Indenture, which event of default results in the Convertible Notes becoming due and payable before their stated maturity, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such event of default (A) Counterparty shall be deemed to be the sole Affected Party and the Transaction shall be the sole Affected Transaction and (B) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.
	(i)		Amendments to Equity Definitions.
			(i) Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) at Dealer’s option, the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master Agreement with respect to that Issuer.”

16

			(ii) Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice to Counterparty” in the first sentence of such section.
	(j)		No Set-Off. Neither party shall have the right to set off any obligation that it may have to the other party under this Transaction against any obligation such other party may have to it, whether arising under the Agreement, this Confirmation or any other agreement between the parties hereto, by operation of law or otherwise.
	(k)		Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If in respect of this Transaction, 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, Merger Event or Tender Offer, 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) 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 Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the Merger Date, the Tender Offer Date, the Announcement Date (in the case of Nationalization, Insolvency or Delisting), 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 reasonable 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 and means that Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, 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.

17

Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit, 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. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.
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
Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 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 (A) the Shares acquired by Dealer for the purpose of hedging its obligations pursuant to this Transaction (the “Hedge Shares”) or (B) any Early Unwind Shares delivered to Dealer pursuant to Section 9(s) (any such Hedge Shares or Early Unwind Shares, “Restricted Shares”) cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Restricted 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 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

18

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 paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Restricted 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 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 Restricted Shares in a private placement), or (iii) purchase the Restricted Shares from Dealer at the Reference 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)		Right to Extend. Dealer may postpone, in whole or in part, any Settlement Date or any other date of valuation or delivery by Dealer or add additional Settlement Dates or any other date of valuation or delivery, with respect to some or all of the Options hereunder, if Dealer reasonably determines, in its discretion, 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.
	(p)		Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are senior to the claims of common stockholders of Counterparty in any United States 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.
	(q)		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), 546(e), 546(g), 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; and (c) each payment and delivery of cash, securities or other property hereunder to constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code.
	(r)		Notice of Merger Consideration. 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.

19

	(s)		Early Unwind. (i) In the event the sale of the “Underwritten Securities” (as defined in the Underwriting Agreement) is not consummated with the Underwriters for any reason, or if Counterparty fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment Date or such later date, the “Early Unwind Date”), the 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 Counterparty shall 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 terminating, liquidating, obtaining or reestablishing any hedge or related trading position of Dealer or one or more of its affiliates in connection with the Transaction). 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. Each of Dealer and Counterparty represent and acknowledge to the other that, subject to the proviso included in this Section, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.
			(ii) If an amount is payable by Counterparty to Dealer pursuant to Section 9(s)(i) (a “Reimbursement Obligation”), Counterparty shall have the right, in its sole discretion, to satisfy any such Reimbursement Obligation by delivering to Dealer, on the Exchange Business Day immediately following the Early Unwind Date, the Early Unwind Shares (as defined below) in satisfaction of such Reimbursement Obligation in the manner reasonably requested by Dealer free of payment. The “Early Unwind Shares” shall be a number of Shares equal to the Reimbursement Obligation otherwise payable under Section 9(s)(i) divided by the value to Dealer per Share on the date such Shares are to be delivered as Early Unwind Shares (the “Early Unwind Share Price”), as determined by the Calculation Agent in its discretion using commercially reasonable means, together with cash in lieu of any fractional Shares based on the Early Unwind Share Price. The Calculation Agent shall notify Counterparty of the Early Unwind Share Price at the time of notification of the Reimbursement Obligation. If such Early Unwind Shares are Restricted Shares as set forth in Section 9(m), the Early Unwind Share Price may reflect, in the Calculation Agent’s judgment, a discount applicable to such Early Unwind Shares. If such Early Unwind Shares are not Restricted Shares as set forth in Section 9(m), the Early Unwind Price shall be Relevant Price on the Early Unwind Date. Counterparty shall give irrevocable telephonic notice, confirmed in writing within one Scheduled Trading Day, to Dealer of its election to satisfy any Reimbursement Obligation by delivery of Early Unwind Shares pursuant to this Section 9(s)(ii) no later than 6:00 p.m. (New York City time) on the Early Unwind Date.

20

(iii) Notwithstanding any other provision of this Confirmation or the Agreement, in no event will Counterparty be required to deliver more than the Number of Shares in the aggregate to Dealer pursuant to this Section 9(s). In the event Counterparty shall not have delivered the full number of Shares otherwise applicable as a result of the foregoing sentence (such deficit, the “Deficit Shares”), Counterparty shall be continually obligated to deliver, from time to time until the full number of Deficit Shares have been delivered pursuant to this Section 9(s), Shares when, and to the extent, that (A) Shares are repurchased, acquired or otherwise received by Counterparty or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (B) authorized and unissued Shares reserved for issuance in respect of other transactions prior to such date which prior to the relevant date become no longer so reserved and (C) Counterparty additionally authorizes any unissued Shares that are not reserved for other transactions. Counterparty shall immediately notify Dealer of the occurrence of any of the foregoing events (including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares to be delivered) and promptly deliver the Applicable Percentage of the aggregate number of such Shares thereafter.

(t) Payment by Counterparty. In the event that (i) an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero.

21

Counterparty hereby agrees (a) to check this Confirmation carefully and immediately upon receipt so that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the foregoing (in the exact form provided by Dealer) correctly sets forth the terms of the agreement between Dealer and Counterparty with respect to the Transaction, by manually signing this Confirmation or this page hereof as evidence of agreement to such terms and providing the other information requested herein and immediately returning an executed copy by facsimile to 000-000-0000 (Attention: Equity Division Documentation Unit, by telephone contact 000-000-0000).
