First Expiration Date:		September 15, 2014 (or if such day is not a Scheduled Trading Day, the next following Scheduled Trading Day), subject to Market Disruption Event below.
Daily Number of Warrants:		For any Expiration Date, the Number of Warrants that have not expired or been exercised as of such day, divided by the remaining number of Expiration Dates (including such day), rounded down to the nearest whole number, subject to adjustment pursuant to the provisos to “Expiration Date(s)”.
Automatic Exercise:		Applicable; and means that for each Expiration Date, a number of Warrants equal to the Daily Number of Warrants (as adjusted pursuant to the terms hereof) for such Expiration Date will be deemed to be automatically exercised.
Market Disruption Event:		Section 6.3(a)(ii) of the Equity Definitions is hereby amended by replacing clause (ii) in its entirety with “(ii) an Exchange Disruption, or” and inserting immediately following clause (iii) the phrase “; in each case that the Calculation Agent determines is material.”

Notwithstanding the foregoing, if (i) any Expiration Date is a Disrupted Day and (ii) the Calculation Agent determines that such Expiration Date shall be an Expiration Date for fewer than the Daily Number of Warrants, as described above, then the Settlement Price for the relevant Valuation Date shall be the volume-weighted average price per Share on such Valuation Date on the Exchange, as determined by the Calculation Agent based on such sources as it deems appropriate using a volume-weighted methodology, for the portion of such Valuation Date for which the Calculation Agent determines there is no Market Disruption Event.
Settlement Date(s):		As determined in reference to Section 9.4 of the Equity Definitions, subject to Section 9(k)(i) hereof.
Other Applicable Provisions:		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 “Physically-settled” shall be read as references to “Net Share Settled.” “Net Share Settled” in relation to any Warrant means that Net Share Settlement is applicable to that Warrant.
Representation and Agreement:		Notwithstanding Section 9.11 of the Equity Definitions, the parties acknowledge that any Shares delivered to Dealer may be, upon delivery, subject to restrictions and limitations arising from Company’s status as issuer of the Shares under applicable securities laws.

Each of the representations and warranties of Company set forth in Section 3 of the Underwriting Agreement (the “Underwriting Agreement”) dated as of June 4, 2009 between Company and X.X. Xxxxxx Securities Inc., Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated, Wachovia Capital Markets, LLC and Credit Suisse Securities (USA) LLC as representative of the Underwriters party thereto (the "Underwriters”), are true and correct and are hereby deemed to be repeated to Dealer on the date hereof and on and as of the Premium Payment Date as if set forth herein. Company hereby further represents and warrants to Dealer that:

	(a)		Company has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of this Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Company’s part; and this Confirmation has been duly and validly executed and delivered by Company and constitutes its valid and binding obligation, enforceable against Company in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.
	(b)		Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Company hereunder will conflict with or result in a breach of the certificate of incorporation or by-laws (or any equivalent documents) of Company, or any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or any agreement or instrument to which Company or any of its subsidiaries is a party or by which Company or any of its subsidiaries is bound or to which Company or any of its subsidiaries is subject, or constitute a default under, or result in the creation of any lien under, any such agreement or instrument.
	(c)		No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Company of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act of 1933, as amended (the “Securities Act”) or state securities laws.
	(d)		The Shares of Company initially issuable upon exercise of the Warrant by the net share settlement method (the “Warrant Shares”) have been reserved for issuance by all required corporate action of Company. The Warrant Shares have been duly authorized and, when delivered against payment therefor (which may include Net Share Settlement in lieu of cash) and otherwise as contemplated by the terms of the Warrant following the exercise of the Warrant in accordance with the terms and conditions of the Warrant, will be validly issued, fully-paid and non-assessable, and the issuance of the Warrant Shares will not be subject to any preemptive or similar rights.
	(e)		Company is not and will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.
	(f)		Company is an “eligible contract participant” (as such term is defined in Section 1a(12) of the Commodity Exchange Act, as amended (the “CEA”)) because one or more of the following is true:

8

Company is a corporation, partnership, proprietorship, organization, trust or other entity and:

	(A)		Company has total assets in excess of USD 10,000,000;
	(B)		the obligations of Company hereunder are guaranteed, or otherwise supported by a letter of credit or keepwell, support or other agreement, by an entity of the type described in Section 1a(12)(A)(i) through (iv), 1a(12)(A)(v)(I), 1a(12)(A)(vii) or 1a(12)(C) of the CEA; or
	(C)		Company has a net worth in excess of USD 1,000,000 and has entered into this Agreement in connection with the conduct of Company’s business or to manage the risk associated with an asset or liability owned or incurred or reasonably likely to be owned or incurred by Company in the conduct of Company’s business.

	(g)		Company and each of its affiliates is not, on the date hereof, in possession of any material non-public information with respect to Company.
	(h)		Company is entering into the Transaction for bona fide business purposes and not for speculative purposes.

9. Other Provisions:

	(a)		Opinions. Company shall deliver to Dealer an opinion of counsel, dated as of the Trade Date and reasonably acceptable to Dealer in form and substance, with respect to (i) due incorporation, existence and good standing of Company in Delaware, (ii) Company’s qualifications as a foreign corporation and good standing in Texas, (iii) the due authorization, execution and delivery of the Confirmation, and (iv) the absence of conflict of the execution and delivery of the Confirmation with any material agreement required to be filed as any exhibit to Company’s Annual Report on Form 10-K, Company’s charter documents and any applicable law or regulation. Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement.
	(b)		Repurchase Notices. Company shall, on any day on which Company 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 number of outstanding Shares on such day, subject to any adjustments provided herein, is (i) less than 59.2 million (in the case of the first such notice) or (ii) thereafter more than 3.0 million less than the number of Shares included in the immediately preceding Repurchase Notice. Company 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 actually may become subject to, as a result of Company’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, such Indemnified Person shall promptly notify Company in writing, and Company, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Company may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Company agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Company shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which

9

			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 Company under such paragraph, 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 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person 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. Company 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 Company, other than the distribution of USD 325,000,000 principal amount of 4.25% convertible senior notes due 2014 being made on the date hereof. Company shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.
	(d)		No Manipulation. Company 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. Company may not transfer any of its rights or obligations under this Transaction without the prior written consent of Dealer. Dealer may, without Company’s consent, transfer or assign all or any part of its rights or obligations under this Transaction to any third party. If at any time at which (1) the Section 16 Percentage exceeds 7.5%, (2) the Warrant 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 Warrants 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 Warrant 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 Warrant Equity Percentage will be equal to or less than 14.5%, and (3) the Share Amount 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 Warrants equal to the number of Warrants underlying the Terminated Portion, (2) Company 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(j) shall apply to any amount that is payable by Company to Dealer pursuant to this sentence as if Company 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 (the “Dealer Group”) 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 “Warrant 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 Warrants and the Warrant Entitlement and (y) the aggregate number of Shares underlying any other warrants purchased by Dealer from Company, and (B) the denominator of which is the number of Shares

10

			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. 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 Company, 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 Company to the extent of any such performance.
	(f)		Dividends. If at any time during the period from and including the Effective Date, to and including the final Expiration Date, an ex-dividend date for a cash dividend occurs with respect to the Shares, then the Calculation Agent will adjust any of the Strike Price, Number of Warrants and/or Daily Number of Warrants to preserve the fair value of the Warrants to Dealer after taking into account such dividend.
	(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 Company’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 Company 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 Company 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 Company 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 Company for or arising from (A) any failure by either Dealer or Company 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 Company under or in connection with this Transaction. Each of Dealer and Company 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 Company 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.

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

(F) Section 12.9(b)(v) of the Equity Definitions is hereby amended by:

(x) adding the word “or” immediately before subsection “(B)” and deleting the comma at the end of subsection (A); and

(y) (1) deleting subsection (C) in its entirety, (2) deleting the word “or” immediately preceding subsection (C) and (3) deleting the penultimate sentence in its entirety and replacing it with the sentence “The Hedging Party will determine the Cancellation Amount payable by one party to the other.”

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

(A) A “person” or “group” within the meaning of Section 13(d) of the Exchange Act, other than Company, its subsidiaries and its and their employee benefit plans, has become the direct or indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of the common equity of Company representing more than 50% of the voting power of such common equity.

12

(B) Consummation of any share exchange, consolidation or merger of Company or any other transaction or series of transactions pursuant to which the Shares will be converted into cash, securities or other property or any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of Company and its subsidiaries, taken as a whole, to any person other than one of Company’s subsidiaries; provided, however, that a transaction where the holders of all classes of Company’s common equity immediately prior to such transaction that is a share exchange, consolidation or merger own, directly or indirectly, more than 50% of all classes of common equity of the continuing or surviving corporation or transferee or the parent thereof immediately after such event shall not constitute an Additional Termination Event. Notwithstanding the foregoing, any event set forth in this clause (B) shall not constitute an Additional Termination Event if at least 90% of the consideration received or to be received by holders of the Shares, excluding cash payments for fractional Shares, in connection with such event consists of shares of common stock traded on the New York Stock Exchange, the NASDAQ Global Market or the NASDAQ Global Select Market (or any of their respective successors) or which will be so traded or quoted when issued or exchanged in connection with such event.

(C) An event of default as defined in any mortgage, indenture or instrument under which there may be issued, or by which there may be secured or evidenced, any indebtedness of Company or any principal subsidiary (other than Exterran Partners, L.P. and its subsidiaries, so long as Exterran Partners, L.P. and its subsidiaries are not restricted subsidiaries of Company, as such term is defined in the Senior Secured Credit Agreement dated August 20, 2007 by and among Company, Exterran Canada, Limited Partnership and the agents and lenders party thereto) for money borrowed, whether such indebtedness now exists or shall hereafter be created, shall happen and shall result in such indebtedness in principal amount in excess of $50 million becoming or being declared due and payable prior to the date on which it would otherwise become due and payable.

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

(E) At any time on any day during the period from and including the Trade Date, to and including the final Expiration Date, (1) the Share Delivery Quantity of Shares that would be deliverable (if such time were the Valuation Time and such date were the Exercise Date and Valuation Date for a number of Warrants equal to the Number of Warrants as of such date and Net Share Settlement applied) exceeds a number of Shares equal to 75% of the Maximum Number of Shares, or (2) Company makes a public announcement of any transaction or event that, in the reasonable opinion of Dealer would, upon consummation of such transaction or upon the occurrence of such event, as applicable, and after giving effect to any applicable adjustments hereunder, cause the Share Delivery Quantity of Shares immediately following the consummation of such transaction or the occurrence of such event (determined as if the time immediately following the consummation of such transaction or the occurrence of such event were the Valuation Time and the date upon which such transaction is consummated or such event occurs were the Exercise Date and Valuation Date for a number of Warrants equal to the Number of Warrants as of such Date and Net Share Settlement applied) to exceed a number of Shares equal to 75% of the Maximum Number of Shares.

13

	(i)		No Collateral or Setoff. Notwithstanding any provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Company hereunder are not secured by any collateral. Obligations under this Transaction shall not be set off by Company against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise. Any provision in the Agreement with respect to the satisfaction of Company’s payment obligations to the extent of Dealer ‘s payment obligations to Company in the same currency and in the same Transaction (including, without limitation Section 2(c) thereof) shall not apply to Company and, for the avoidance of doubt, Company shall fully satisfy such payment obligations notwithstanding any payment obligation to Company by Dealer in the same currency and in the same Transaction. 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 such Section 6(e) with respect to (a) this Transaction and (b) all other Transactions, and (2) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement. For the avoidance of doubt and notwithstanding anything to the contrary provided in this Section 9(i), in the event of bankruptcy or liquidation of either Company or Dealer 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.
	(j)		Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If, in respect of this Transaction, an amount is payable by Company to Dealer, (i) pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, (ii) pursuant to Section 6(d)(ii) of the Agreement or (iii) pursuant to Section 9(t) (a “Payment Obligation”), Company shall have the right, in its sole discretion, to satisfy any such Payment Obligation by the Share Termination Alternative (as defined below) (except that Company shall not make such an election in the event of a Nationalization, Insolvency, Merger Event or Tender Offer in which the consideration to be paid to holders of shares consists solely of cash or an Event of Default in which Company is the Defaulting Party or a Termination Event in which Company is the Affected Party, other than an Event of Default of the type described in 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 Company’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, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, or no later than 6:00 p.m. (New York City time) on the Early Unwind Date, as applicable; provided that if Company does not validly elect to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its reasonable discretion, to require Company to satisfy its Payment Obligation by the Share Termination Alternative. Notwithstanding the foregoing, Company’s or Dealer’s right to elect satisfaction of a Payment Obligation in the Share Termination Alternative as set forth in this clause shall only apply to Transactions under this Confirmation and, notwithstanding anything to the contrary in the Agreement, (1) separate amounts shall be calculated with respect to (a) Transactions hereunder and (b) all other Transactions under the Agreement, and (2) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement, subject to, in the case of clause (a), Company’s Share Termination Alternative right hereunder.

Share Termination Alternative: If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “Share Termination Payment Date”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, or on the Exchange Business Day immediately following the date on which the Payment Obligation would otherwise be due pursuant to Section 9(t), as applicable, subject to paragraph (k)(i) below, in satisfaction, subject to paragraph (k)(ii) below, of the Payment Obligation in the manner reasonably requested by Dealer free of payment.

14

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

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.

15

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

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

16

			In the event Company shall not have delivered the full number of Restricted Shares otherwise applicable as a result of the proviso above relating to the Maximum Number of Shares (such deficit, the “Deficit Restricted Shares”), Company shall be continually obligated to deliver, from time to time until the full number of Deficit Restricted Shares have been delivered pursuant to this paragraph, Restricted Shares when, and to the extent, that (i) Shares are repurchased, acquired or otherwise received by Company or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (ii) 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 (iii) Company additionally authorizes any unissued Shares that are not reserved for other transactions. Company shall immediately notify Dealer of the occurrence of any of the foregoing events (including the number of Shares subject to clause (i), (ii) or (iii) and the corresponding number of Restricted Shares to be delivered) and promptly deliver such Restricted Shares thereafter.
	(ii)		If Company elects to settle the Transaction pursuant to this clause (ii) (a “Registration Settlement”), then Company shall promptly (but in any event no later than the beginning of the Resale Period) file and use its reasonable best efforts to make effective under the Securities Act a registration statement or supplement or amend an outstanding registration statement in form and substance reasonably satisfactory to Dealer, to cover the resale of such Restricted Shares in accordance with customary resale registration procedures, including covenants, conditions, representations, underwriting discounts (if applicable), commissions (if applicable), indemnities due diligence rights, opinions and certificates, and such other documentation as is customary for equity resale underwriting agreements, all reasonably acceptable to Dealer. If Dealer, in its sole reasonable discretion, is not satisfied with such procedures and documentation Private Placement Settlement shall apply. If Dealer is satisfied with such procedures and documentation, it shall sell the Restricted Shares pursuant to such registration statement during a period (the “Resale Period”) commencing on the Exchange Business Day following delivery of such Restricted Shares (which, for the avoidance of doubt, shall be (x) the Share Termination Payment Date in case of settlement in Share Termination Delivery Units pursuant to paragraph (j) above or (y) the Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants) and ending on the earliest of (i) the Exchange Business Day on which Dealer completes the sale of all Restricted Shares or, in the case of settlement of Share Termination Delivery Units, a sufficient number of Restricted Shares so that the realized net proceeds of such sales equals or exceeds the Payment Obligation (as defined above), (ii) the date upon which all Restricted Shares have been sold or transferred pursuant to Rule 144 (or similar provisions then in force) or Rule 145(d)(2) (or any similar provision then in force) under the Securities Act and (iii) the date upon which all Restricted Shares may be sold or transferred by a non-affiliate pursuant to Rule 144 (or any similar provision then in force) or Rule 145(d)(2) (or any similar provision then in force) under the Securities Act. If the Payment Obligation exceeds the realized net proceeds from such resale, Company shall transfer to Dealer by the open of the regular trading session on the Exchange on the Exchange Trading Day immediately following the last day of the Resale Period the amount of such excess (the “Additional Amount”) in cash or in a number of Shares (“Make-whole Shares”) in an amount that, based on the Settlement Price on the last day of the Resale Period (as if such day was the “Valuation Date” for purposes of computing such Settlement Price), has a dollar value equal to the Additional Amount; provided that in no event shall the number of Make-Whole Shares exceed the Maximum Number of Shares. The Resale Period shall continue to enable the sale of the Make-whole Shares. If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration Settlement shall apply. This provision shall be applied successively until the Additional Amount is equal to zero. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Number of Shares.

17

(iii) Without limiting the generality of the foregoing, Company agrees that any Restricted Shares delivered to Dealer, as purchaser of such Restricted Shares, (i) may be transferred by and among Dealer and its affiliates and Company shall effect such transfer without any further action by Dealer and (ii) after the period of 6 months from the Trade Date (or 1 year from the Trade Date if, at such time, informational requirements of Rule 144(c) are not satisfied with respect to Company) has elapsed after any Settlement Date for such Restricted Shares, Company shall promptly remove, or cause the transfer agent for such Restricted Shares to remove, any legends referring to any such restrictions or requirements from such Restricted Shares upon request by Dealer (or such affiliate of Dealer) to Company or such transfer agent, without any requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Dealer (or such affiliate of Dealer).

			If the Private Placement Settlement or the Registration Settlement shall not be effected as set forth in clauses (i) or (ii), as applicable, then failure to effect such Private Placement Settlement or such Registration Settlement shall constitute an Event of Default with respect to which Company shall be the Defaulting Party.
	(l)		Limit on Beneficial Ownership. Notwithstanding any other provisions hereof, Dealer may not exercise any Warrant hereunder, have the “right to acquire” (within the meaning of NYSE Rule 312.04(g)) Shares upon exercise of any Warrant hereunder or be entitled to take delivery of any Shares deliverable hereunder, and Automatic Exercise shall not apply with respect to any Warrant hereunder, to the extent (but only to the extent) that, after such receipt of any Shares upon the exercise of such Warrant or otherwise hereunder, (i) the Share Amount would exceed the Post-Effective Limit, or (ii) Dealer Group would directly or indirectly beneficially own (as such term is defined for purposes of Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) in excess of 7.5% of the then outstanding Shares (the “Threshold Number of Shares”). Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery, (i) the Share Amount would exceed the Post-Effective Limit, or (ii) Dealer Group would directly or indirectly so beneficially own in excess of the Threshold Number of Shares. If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Company’s obligation to make such delivery shall not be extinguished and Company shall make such delivery as promptly as practicable after, but in no event later than one Business Day after, Dealer gives notice to Company that, after such delivery, (i) the Share Amount would not exceed the Post-Effective Limit, and (ii) Dealer Group would not directly or indirectly so beneficially own in excess of the Threshold Number of Shares. Company agrees to use its reasonable best efforts to seek approval from its shareholders in accordance with the requirements of NYSE Rule 312.03(c) for the issuance pursuant to the Transaction of a number of Shares equal to 1.5 times the original Number of Shares. If Company succeeds in obtaining such approval for such an increase, then (A) the Maximum Number of Shares shall be automatically increased to 1.5 times the original Number of Shares and (B) the Additional Termination Event in Section 9(h)(ii)(E) shall no longer be applicable.

18

	(m)		Share Deliveries. Company acknowledges and agrees that, to the extent the holder of this Warrant is not then an affiliate and has not been an affiliate for 90 days (it being understood that Dealer will not be considered an affiliate under this paragraph solely by reason of its receipt of Shares pursuant to this Transaction), and otherwise satisfies all holding period and other requirements of Rule 144 of the Securities Act applicable to it, any delivery of Shares or Share Termination Delivery Property hereunder at any time after 6 months from the Trade Date (or 1 year from the Trade Date if, at such time, informational requirements of Rule 144(c) are not satisfied with respect to Company) shall be eligible for resale under Rule 144 of the Securities Act and Company agrees to promptly remove, or cause the transfer agent for such Shares or Share Termination Delivery Property, to remove, any legends referring to any restrictions on resale under the Securities Act from the Shares or Share Termination Delivery Property. Company further agrees that any delivery of Shares or Share Termination Delivery Property prior to the date that is 6 months from the Trade Date (or 1 year from the Trade Date if, at such time, informational requirements of Rule 144(c) are not satisfied with respect to Company), may be transferred by and among Dealer and its affiliates and Company shall effect such transfer without any further action by Dealer. Notwithstanding anything to the contrary herein, Company agrees that any delivery of Shares or Share Termination Delivery Property shall be effected by book-entry transfer through the facilities of DTC, or any successor depositary, if at the time of delivery, such class of Shares or class of Share Termination Delivery Property is in book-entry form at DTC or such successor depositary. Notwithstanding anything to the contrary herein, to the extent the provisions of Rule 144 of the Securities Act or any successor rule are amended, or the applicable interpretation thereof by the Securities and Exchange Commission or any court change after the Trade Date, the agreements of Company herein shall be deemed modified to the extent necessary, in the opinion of outside counsel of Company, to comply with Rule 144 of the Securities Act, as in effect at the time of delivery of the relevant Shares or Share Termination Delivery Property.
	(n)		Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to this Transaction. Each party (i) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into this Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.
	(o)		Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Company 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 Company relating to such tax treatment and tax structure.
	(p)		Maximum Share Delivery. Notwithstanding any other provision of this Confirmation or the Agreement, in no event will Company be required to deliver more than the Maximum Number of Shares in the aggregate to Dealer in connection with this Transaction, subject to the provisions regarding Deficit Restricted Shares.
	(q)		Right to Extend. Dealer may postpone, in whole or in part, any Expiration Date or any other date of valuation or delivery with respect to some or all of the relevant Warrants (in which event the Calculation Agent shall make appropriate adjustments to the Daily Number of Warrants with respect to one or more Expiration Dates) if Dealer determines, in its commercially reasonable judgment, 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 Issuer or an affiliated purchaser of Issuer, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer.

19

	(r)		Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Company with respect to the Transaction that are senior to the claims of common stockholders of Company in any United States bankruptcy proceedings of Company; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Company of its obligations and agreements with respect to the Transaction; provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.
	(s)		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.
	(t)		Early Unwind. 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 Company 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 Company 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 Company 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 Company of such amount and Company shall pay such amount in immediately available funds on the Early Unwind Date. Each of Dealer and Company 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.
	(u)		Payment by Dealer. 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, Dealer owes to Company an amount calculated under Section 6(e) of the Agreement, or (ii) Dealer owes to Company, 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.

20

Company 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 Company 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).
