Date:		November 10, 2010

          This master confirmation (this “Master Confirmation”), dated as of November 10, 2010 is intended to supplement the terms and provisions of certain Transactions (each, a “Transaction”) entered into from time to time between Barclays Bank PLC (“Barclays”), through its agent Barclays Capital Inc. (the “Agent”), and Aspen Insurance Holdings Limited (“Counterparty”). Barclays Bank PLC is not a member of the Securities Investor Protection Corporation. Barclays is regulated by the Financial Services Authority. This Master Confirmation, taken alone, is neither a commitment by either party to enter into any Transaction nor evidence of a Transaction. The terms of any particular Transaction shall be set forth in (i) a Supplemental Confirmation in the form of Schedule A hereto (a “Supplemental Confirmation”), which shall reference this Master Confirmation and supplement, form a part of, and be subject to this Master Confirmation and (ii) a Trade Notification in the form of Schedule B hereto (a “Trade Notification”), which shall reference the relevant Supplemental confirmation and supplement, form a part of, and be subject to such Supplemental Confirmation. This Master Confirmation, each Supplemental Confirmation and the related Trade Notification together shall constitute a “Confirmation” as referred to in the Agreement specified below.

          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., are incorporated into this Master Confirmation. This Master Confirmation, each Supplemental Confirmation and the related Trade Notification evidence a complete binding agreement between Counterparty and Barclays as to the subject matter and terms of each Transaction to which this Master Confirmation, such Supplemental Confirmation and Trade Notification relate and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

          This Master Confirmation, each Supplemental Confirmation and each Trade Notification supplement, form a part of, and are subject to an agreement in the form of the 1992 ISDA Master Agreement (Multicurrency —Cross Border) (the “Agreement”) as if Barclays and Counterparty had executed the Agreement on the date of this Master Confirmation (but without any Schedule except for (i) the election of Loss and Second Method, New York law (without regard to the conflicts of law principles)

as the governing law and US Dollars (“USD”) as the Termination Currency, (ii) the election that subparagraph (ii) of Section 2(c) will not apply to the Transactions, (iii) the replacement of the word “third” in the last line of Section 5(a)(i) with the word “first” and (iv) the election that the “Cross Default” provisions of Section 5(a)(vi) shall apply to Counterparty, with a “Threshold Amount” of USD5O million).

          All provisions contained or incorporated by reference in the Agreement shall govern this Master Confirmation, each Supplemental Confirmation and each Trade Notification except as expressly modified herein.

          If, in relation to any Transaction to which this Master Confirmation, a Supplemental Confirmation and a Trade Notification relate, there is any inconsistency between the Agreement, this Master Confirmation, any Supplemental Confirmation, any Trade Notification and the Equity Definitions, the following will prevail for purposes of such Transaction in the order of precedence indicated: (i) such Trade Notification, (ii) such Supplemental Confirmation; (iii) this Master Confirmation; (iv) the Agreement; and (v) the Equity Definitions.

1. Each Transaction constitutes a Share Forward Transaction for the purposes of the Equity Definitions. Set forth below are the terms and conditions which, together with the terms and conditions set forth in the related Supplemental Confirmation and Trade Notification (in respect of the relevant Transaction), shall govern each such Transaction.

General Terms:

Trade Date: For each Transaction, as set forth in the Supplemental Confirmation.
Buyer:		Counterparty
Seller:		Barclays
Shares:		Ordinary Shares $0.0015144558 par value of Counterparty (Ticker: AHL)
Forward Price:		The average of the VWAP Prices for each Exchange Business Day in the Calculation Period.
VWAP Price:		For any Exchange Business Day, as determined by the Calculation Agent based on the New York Stock Exchange 10b-18 Volume Weighted Average Price per Share for the regular trading session (including any extensions thereof) of the Exchange on such Exchange Business Day (without regard to pre-open or after hours trading outside of such regular trading session for such Exchange Business Day), as published by Bloomberg at 4:15 p.m. New York time (or 15 minutes following the end of any extension of the regular trading session) on such Exchange Business Day, on Bloomberg page “AHL.N <Equity> AQR-SEC” (or any successor thereto). For purposes of calculating the VWAP Price, the Calculation Agent will include only those trades that are reported during the period of time during which Counterparty could purchase its own shares under Rule 10b-1 8(b)(2) and pursuant to the conditions of Rule 10b-18(b)(3), each under the Exchange Act (as defined herein) (such trades, “Rule l0b-18 eligible transactions”).
Forward Price Adjustment Amount:		For each Transaction, as set forth in the Supplemental Confirmation.

Calculation Period:		The period from and including the first Exchange Business Day immediately Following the Hedge Completion Date to and including the Termination Date (as adjusted in accordance with the provisions hereof).
Termination Date:		For each Transaction, the Scheduled Termination Date set forth in the Supplemental Confirmation (as the same may be postponed in accordance with the provisions hereof); provided that Barclays shall have the right to designate any date (the “Accelerated Termination Date”) on or after the First Acceleration Date to be the Termination Date by providing notice to Counterparty of any such designation on such date.
First Acceleration Date:		For each Transaction, as set forth in the Supplemental Confirmation.
Hedge Period:		The period from and including the day immediately after the Trade Date to and including the Hedge Completion Date (as adjusted in accordance with the provisions hereof).
Hedge Completion Date:		For each Transaction, as set forth in the Trade Notification, to be the Exchange Business Day on which Barclays finishes establishing its initial Hedge Positions in respect of such Transaction, as reasonably determined by Barclays, which date shall be no later than the Cut-off Hedge Completion Date if such date is specified.
Cut-off Hedge Completion Date:		For each Transaction, if applicable, as set forth in the Trade Notification.
Hedge Period Reference Price:		For each Transaction, as set forth in the Trade Notification, the volume weighted average of the Market Purchase Price and the Block Purchase Price. “Market Purchase Price” means the volume weighted average of the VWAP Prices for all Scheduled Trading Days on which Barclays purchases Shares on the Exchange during the Hedge Period where the daily weight for the calculation of the volume weighted average is equal to the quotient of (i) the number of Shares Barclays purchases on such day as part of establishing its hedge position with respect to such Transaction divided by (ii) the total number of Shares Barclays purchases on the Exchange as part of establishing its hedge position with respect to this Transaction during the Hedge Period. “Block Purchase Price” means the arithmetic average purchase price per Share paid by Barclays in Rule 10b-18 block purchases (as that term is defined below) made as part of establishing its hedge position with respect to such Transaction during the Hedge Period.
Market Disruption Event:		The definition of “Market Disruption Event” in Section 6.3(a) of the Equity Definitions is hereby amended by deleting the words “at any time during the one-hour period that ends at the relevant Valuation Time, Latest Exercise Time, Knock-in Valuation Time or Knock-out Valuation Time, as the case may be” and inserting the words “at any

		time on any Scheduled Trading Day during the Hedge Period, Calculation Period or Settlement Valuation Period” after the word “material,” in the third line thereof.
		Notwithstanding anything to the contrary in the Equity Definitions, to the extent that a Disrupted Day occurs in the Hedge Period, the Calculation Period, or the Settlement Valuation Period, the Calculation Agent may in good faith and acting in a commercially reasonable manner postpone the Hedge Completion Date, Cut-off Hedge Completion Date or the Termination Date, or extend the Settlement Valuation Period, as the case may be. In such event, the Calculation Agent must determine whether (i) such Disrupted Day is a Disrupted Day in full, in which case the VWAP Price for such Disrupted Day shall not be included for purposes of determining the Hedge Period Reference Price, the Forward Price or the Settlement Price, as the case may be, or (ii) such Disrupted Day is a Disrupted Day only in part, in which case the VWAP Price for such Disrupted Day shall be determined by the Calculation Agent based on Rule 10b-18 eligible transactions in the Shares on such Disrupted Day effected before the relevant Market Disruption Event occurred and/or after the relevant Market Disruption Event ended, and the weighting of the VWAP Price for the relevant Exchange Business Days during the Hedge Period, the Calculation Period or the Settlement Valuation Period, as the case may be, shall be adjusted in a commercially reasonable manner by the Calculation Agent for purposes of determining the Hedge Period Reference Price, the Forward Price or the Settlement Price, as the case may be, with such adjustments based on, among other factors, the duration of any Market Disruption Event and the volume, historical trading patterns and price of the Shares.
		If a Disrupted Day occurs during the Hedge Period, the Calculation Period or the Settlement Valuation Period, as the case may be, and each of the nine immediately following Scheduled Trading Days is a Disrupted Day, then the Calculation Agent, in its good faith and commercially reasonable discretion, may either (i) deem such ninth Scheduled Trading Day to be an Exchange Business Day and determine the VWAP Price for such ninth Scheduled Trading Day using its good faith estimate of the value of the Shares on such ninth Scheduled Trading Day based on the volume, historical trading patterns and price of the Shares and such other factors as it deems appropriate or (ii) further extend the Hedge Period, the Calculation Period or the Settlement Valuation Period, as the case may be, as it deems necessary to determine the VWAP Price.

The notice shall not specify, and Barclays shall not otherwise communicate to Counterparty, the reason for Barclays’s election to suspend the Hedge Period, the Calculation Period and/or the Settlement Valuation Period, as the case may be.

(d) In the event that the Calculation Period is extended or suspended pursuant to any provision hereof (including, without limitation, pursuant to Section 9(d) below), the Calculation Agent, in its good faith and commercially reasonable discretion, shall adjust any relevant terms of the related Transaction if necessary to preserve as nearly as practicable the economic terms of such Transaction prior to such extension; provided that Counterparty shall not be required to make any additional cash payments or deliver any Shares in connection with any such adjustments.

(c) promptly provide Barclays with written notice specifying (i) Counterparty’s average daily Rule 10b-18 Purchases (as defined in Rule 10b-18) during the three full calendar months immediately preceding the Announcement Date that were not effected through Barclays or its affiliates and (ii) the number of Shares purchased pursuant to the proviso in Rule 10b-18(b)(4) under the Exchange Act for the three full calendar months preceding the Announcement Date. Such written notice shall be deemed to be a certification by Counterparty to Barclays that such information is true and correct. In addition, Counterparty shall promptly notify Barclays of the earlier to occur of the completion of such transaction and the completion of the vote by target shareholders. Counterparty acknowledges that any such notice may cause the terms of any Transaction to be adjusted or such Transaction to be terminated; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in Section 6; and

(d) Barclays in its sole discretion may (i) make adjustments to the terms of any Transaction, including, without limitation, the Termination Date, the Forward Price Adjustment Amount and the Maximum Shares to account for the number of Shares that could be purchased on each day during the Hedge Period or the Calculation Period in compliance with Rule 10b-1 8 following such public announcement, provided that Counterparty shall not be required to make any additional cash payments or deliver any Shares in connection with any such adjustments (unless otherwise provided for in Sections 10 or 15 below) or (ii) treat the occurrence of such public announcement as an Additional Termination Event with Counterparty as the sole Affected Party.

“Merger Transaction” means any merger, acquisition or similar transaction involving a recapitalization as contemplated by Rule 10b- 18(a)(13)(iv) under the Exchange Act.

10.

Special Provisions for Friendly Transaction Announcements. (a) If a Friendly Transaction Announcement occurs on or prior to the Settlement Date for any Transaction, then the Number of Shares to be Delivered for such Transaction shall be determined as if the words “less than the Minimum Shares and not” were deleted from the definition thereof. If a Friendly Transaction Announcement occurs after the Trade Date, but prior to the First Acceleration Date of any Transaction, the First Acceleration Date shall be the date of such Friendly Transaction Announcement. If a Friendly Transaction Announcement occurs after the Settlement Date for any Transaction or any earlier date of termination or cancellation of such Transaction pursuant to Section 6 of the Agreement or Article 12 of the Equity Definitions, then a second settlement of such Transaction (a “Second Settlement”) shall occur (notwithstanding such earlier termination or cancellation) with a Number of Shares to be Delivered equal to the lesser of (i) zero and (ii) (x) the Number of Shares to be Delivered determined pursuant to the first sentence of this paragraph as if such Friendly Transaction Announcement occurred prior to such Settlement Date minus (y) the Number of Shares to be Delivered determined pursuant to Section 1 of this Confirmation (provided that in the case of a Second Settlement occurring after such an early termination or cancellation, a Number of Shares to be Delivered shall not be determined and instead a Forward Cash Settlement Amount will be determined as provided in Annex A). If the Number of Shares to be Delivered for any settlement of any Transaction is a negative number, then the terms of the Counterparty Settlement Provisions in Annex A shall apply.

(b) “Friendly Transaction Announcement” means (i) an Acquisition Transaction Announcement by Counterparty or its board of directors prior to the last day of the Relevant Period or any earlier date of termination or cancellation of the relevant Transaction pursuant to Section 6 of the

Agreement or Article 12 of the Equity Definitions (such date, the “Actual Termination Date”), (ii) an announcement by Counterparty or its board of directors prior to the date three months following the Scheduled Termination Date that an Acquisition Transaction that is the subject of an Acquisition Transaction Announcement occurring prior to the Actual Termination Date has been approved, agreed to, recommended by or otherwise consented to by Counterparty or its board of directors, or negotiated by Counterparty or any authorized representative of Counterparty, or (iii) where Counterparty or its board of directors has a legal obligation to make a recommendation to its shareholders in respect of any such Acquisition Transaction prior to the date three months following the Scheduled Termination Date, the absence of a recommendation that its shareholders reject such transaction.

(c) “Acquisition Transaction Announcement” means (i) the announcement of an Acquisition Transaction, (ii) an announcement that Counterparty or any of its subsidiaries has entered into an agreement, a letter of intent or an understanding designed to result in an Acquisition Transaction, (iii) the announcement of the intention to solicit or enter into, or to explore strategic alternatives or other similar undertaking that may include, an Acquisition Transaction, or (iv) any other announcement that in the reasonable judgment of the Calculation Agent may result in an Acquisition Transaction. For the avoidance of doubt, announcements as used in the definition of Acquisition Transaction Announcement refer to any public announcement whether made by the Issuer or a third party.

(d) “Acquisition Transaction” means (i) any Merger Event (for purposes of this definition the definition of Merger Event shall be read with the references therein to “100%” being replaced by “25%” and to “50%” by “67.5% and without reference to the clause beginning immediately following the definition of Reverse Merger therein to the end of such definition) or Tender Offer, or any other transaction involving the merger of Counterparty with or into any third party, (ii) the sale or transfer of all or substantially all of the assets of Counterparty, (iii) a recapitalization, reclassification, binding share exchange or other similar transaction, (iv) any acquisition, lease, exchange, transfer, disposition (including by way of spin-off or distribution) of assets (including any capital stock or other ownership interests in subsidiaries) or other similar event by Counterparty or any of its subsidiaries where the aggregate consideration transferable or receivable by or to Counterparty or its subsidiaries exceeds 33% of the market capitalization of Counterparty (excluding, for the avoidance of doubt, transactions solely between or among Counterparty and its subsidiaries) and (v) any transaction in which Counterparty or its board of directors has a legal obligation to make a recommendation to its shareholders in respect of such transaction (whether pursuant to Rule 14e-2 under the Exchange Act or otherwise).

11.

Acknowledgments. The parties hereto intend for:

(a) Each Transaction to be a “securities contract” as defined in Section 741(7) of the Bankruptcy Code, a “swap agreement” as defined in Section l0l(53B) of the Bankruptcy Code and a “forward contract” as defined in Section 101(25) of 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), 362(b)(27), 362(0), 546(e), 546(g), 546(j), 555, 556, 560 and 561 of the Bankruptcy Code;

(b) The Agreement to be a “master netting agreement” as defined in Section 101(38A) of the Bankruptcy Code;

(c) A party’s right to liquidate or terminate any Transaction, net out or offset termination values or payment amounts, and to exercise any other remedies upon the occurrence of any Event of Default or Termination Event under the Agreement with respect to the other party or any Extraordinary Event that results in the termination or cancellation of any Transaction to constitute a “contractual right” (as defined in the Bankruptcy Code);

(d) Any cash, securities or other property transferred as performance assurance, credit support or collateral with respect to each Transaction to constitute “margin payments” and “transfers” (as defined in the Bankruptcy Code); and

(e) All payments for, under or in connection with each Transaction, all payments for the Shares and the transfer of such Shares to constitute “settlement payments” and “transfers” (as defined in the Bankruptcy Code).

12.

Credit Support Documents. The parties hereto acknowledge that no Transaction hereunder is secured by any collateral that would otherwise secure the obligations of Counterparty herein or pursuant to the Agreement.

13.

Limitation on Set-off. (a) Notwithstanding anything to the contrary in the Agreement or the Equity Definitions, the calculation of any Settlement Amounts and Unpaid Amounts shall be calculated separately for (A) all Terminated Transactions in the Shares of the Issuer that qualify as equity under applicable accounting rules (collectively, the “Equity Shares”) as determined by the Calculation Agent and (B) all other Terminated Transactions under the Agreement including, without limitation, Transactions in Shares other than those of the Issuer (collectively, the “Other Shares”) and the netting and set-off provisions of the Agreement shall only operate to provide netting and set-off (i) among Terminated Transactions in the Equity Shares and (ii) among Terminated Transactions in the Other Shares. In no event shall the netting and set-off provisions of the Agreement operate to permit netting and set-off between Terminated Transactions in the Equity Shares and Terminated Transactions in the Other Shares.

(b) The parties agree that upon the occurrence of an Event of Default or Termination Event with respect to a party who is the Defaulting Party or an Affected Party (“X”), the other party (“Y) will have the right (but not be obliged) without prior notice to X or any other person to set-off or apply any obligation of X owed to Y (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation) against any obligation of Y owed to X (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation). Y will give notice to the other party of any set-off effected under this Section 13.

Amounts (or the relevant portion of such amounts) subject to set-off may be converted by Y into the Termination Currency at the rate of exchange at which such party would be able, acting in a reasonable manner and in good faith, to purchase the relevant amount of such currency. If any obligation is unascertained, Y may in good faith estimate that obligation and set-off in respect of the estimate, subject to the relevant party accounting to the other when the obligation is ascertained. Nothing in this Section 13 shall be effective to create a charge or other security interest. This Section 13 shall be without prejudice and in addition to any right of set-off, combination of accounts, lien or other right to which any party is at any time otherwise entitled (whether by operation of law, contract or otherwise).

(c) Notwithstanding anything to the contrary in the foregoing, Barclays agrees not to set off or net amounts due from Counterparty with respect to any Transaction against amounts due from Barclays to Counterparty with respect to contracts or instruments that are not Equity Contracts. “Equity Contract” means any transaction or instrument that does not convey rights to Barclays senior to claims of common stockholders in the event of Counterparty’s bankruptcy.

14.

Delivery of Shares. (a) Barclays may, by notice to Counterparty prior to the Minimum Share Delivery Date (the “Nominal Delivery Date”), elect to deliver the Shares it is required to deliver under “Minimum Share Delivery” (above) on two or more dates (each, a “Staggered Delivery Date”) or at two or more times on the Nominal Delivery Date as follows:

(i) in such notice, Barclays will specify to Counterparty the related Staggered Delivery Dates (each of which will be on or prior to the Nominal Delivery Date, but not prior to the beginning of he Hedge Period) or delivery times and how it will allocate the Shares it is required to deliver under “Minimum Share Delivery” (above) among the Staggered Delivery Dates or delivery times; and

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

15.

Early Termination. In the event that an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to any Transaction (except as a result of a Merger Event in which the consideration or proceeds to be paid to holders of Shares consists solely of cash), if either party would owe any amount to the other party pursuant to Section 6(d)(ii) of the Agreement (any such amount, a “Payment Amount”), then, in lieu of any payment of such Payment Amount, Counterparty may, no later than the Early Termination Date or the date on which such Transaction is terminated, elect to deliver or for Barclays to deliver, as the case may be, to the other party a number of Shares (or, in the case of a Merger Event, a number of units, each comprising the number or amount of the securities or property that a hypothetical older of one Share would receive in such Merger Event (each such unit, an “Alternative Delivery Unit” and, the securities or property comprising such unit, “Alternative Delivery Property”) with a value equal to the Payment Amount, as determined by the Calculation Agent (and the parties agree that, in making such determination of value, the Calculation Agent may take into account a number of factors, including the market price of the Shares or Alternative Delivery Property on the date of early termination and, if such delivery is made by Barclays, the prices at which Barclays purchases Shares or Alternative Delivery Property to fulfil its delivery obligations under this Section 15); provided that in determining the composition of any Alternative Delivery Unit, if the relevant 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. If such delivery is made by Counterparty, paragraphs 2 through 7 of Annex A shall apply as if such delivery were a settlement of the Transaction to which Net Share Settlement (as defined in Annex A) applied, the Cash Settlement Payment Date were the Early Termination Date and the Forward Cash Settlement Amount were zero (0) minus the Payment Amount owed by Counterparty.

16.

Calculations and Payment Date upon Early Termination. The parties acknowledge and agree that in calculating Loss pursuant to Section 6 of the Agreement Barclays may (but need not) determine losses without reference to actual losses incurred but based on expected losses assuming a commercially reasonable (including without limitation with regard to reasonable legal and regulatory guidelines) risk bid were used to determine loss to avoid awaiting the delay associated with closing out any hedge or related trading position in a commercially reasonable manner prior to or sooner following the designation of an Early Termination Date. Notwithstanding Anything to the contrary in Section 6(d)(ii) of the Agreement, all amounts calculated as being due in respect of an Early Termination Date under Section 6(e) of the Agreement will be payable on the day that notice of the amount payable is effective; provided that if Counterparty elects to receive Shares or Alternative Delivery Property in accordance with Section 14, such Shares or Alternative Delivery Property shall be delivered on a date selected by Barclays as promptly as practicable.

17.

Special Provisions for Counterparty Payments. The parties hereby agree that, notwithstanding anything to the contrary herein or in the Agreement, in the event that an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to any Transaction and, as a result, Counterparty owes to Barclays an amount calculated under Section 6(e) of the Agreement (calculated as if the Transactions being terminated on such Early Termination Date were the sole Transactions under the Agreement), such amount shall be deemed to be zero; provided that (i) following a Friendly Transaction Announcement or (ii) if the Initial Shares is greater than the Minimum Shares, this Section 17 shall cease to apply.

18.

Claim in Bankruptcy. Barclays agrees that in the event of the bankruptcy of Counterparty, Barclays shall not have rights or assert a claim that is senior in priority to the rights and claims available to the shareholders of the common stock of Counterparty.

19.

Role of Agent. Each of Barclays and Counterparty acknowledges to and agrees with the other party hereto and to and with the Agent that (i) the Agent is acting as agent for Barclays under the Transaction pursuant to instructions from such party, (ii) the Agent is not a principal or party to the Transaction, and may transfer its rights and obligations with respect to the Transaction, (iii) the Agent shall have no responsibility, obligation or liability, by way of issuance, guaranty, endorsement or otherwise in any manner with respect to the performance of either party under the Transaction, (iv) Barclays and the Agent have not given, and Counterparty is not relying (for purposes of making any investment decision or otherwise) upon, any statements, opinions or representations (whether written or oral) of Barclays or the Agent, other than the representations expressly set forth in this Confirmation or the Agreement, and (v) each party agrees to proceed solely against the other party, and not the Agent, to collect or recover any money or securities owed to it in connection with the Transaction. Each party hereto acknowledges and agrees that the Agent is an intended third party beneficiary hereunder. Counterparty acknowledges that the Agent is an affiliate of Barclays.

20.

Regulatory Provisions. The time of dealing for the Transaction will be confirmed by Barclays upon written request by Counterparty. The Agent will furnish to Counterparty upon written request a statement as to the source and amount of any remuneration received or to be received by the Agent in connection with a Transaction.

21.

Method of Delivery. Whenever delivery of funds or other assets is required hereunder by or to Counterparty, such delivery shall be effected through Agent. In addition, all notices, demands and communications of any kind relating to the Transaction between Barclays and Counterparty shall be transmitted exclusively through Agent.

          (f) The rules of some arbitration forums may impose time limits for bringing a claim in arbitration. In some cases, a claim that is ineligible for arbitration may be brought in court.

(g) The rules of the arbitration forum in which the claim is filed, and any amendments thereto, shall be incorporated into this Confirmation.

     Counterparty agrees that any and all controversies that may arise between Counterparty and Barclays, including, but not limited to, those arising out of or relating to the Agreement or any Transaction hereunder, shall be determined by arbitration conducted before The New York Stock Exchange, Inc. (“NYSE”) or NASD Dispute Resolution (“NASD-DR”), or, if the NYSE and NASD-DR decline to hear the matter, before the American Arbitration Association, in accordance with their arbitration rules then in force. The award of the arbitrator shall be final, and judgment upon the award rendered may be entered in any court, state or federal, having jurisdiction.

     No person shall bring a putative or certified class action to arbitration, nor seek to enforce any pre-dispute arbitration agreement against any person who has initiated in court a putative class action or who is a member of a putative class who has not opted out of the class with respect to any claims encompassed by the putative class action until: (i) the class certification is denied; (ii) the class is decertified; or (iii) Counterparty is excluded from the class by the court. Such forbearance to enforce an agreement to arbitrate shall not constitute a waiver of any rights under this Confirmation except to the extent stated herein”.

Default Settlement Method:		Cash Settlement
Forward Cash Settlement Amount:		The Number of Shares to be Delivered multiplied by the Settlement Price; provided that in the case of a Second Settlement occurring after an early termination or cancellation of the relevant Transaction pursuant to Section 6 of the Agreement or Article 12 of the Equity Definitions, the Forward Cash Settlement Amount shall equal the lesser of (i) zero and (ii)(x) the Payment Amount that would have been calculated for such early termination or cancellation if the words “not less than the Minimum Shares” and “, but not below zero” were deleted from the definition of Number of Shares to be Delivered, as determined by the Calculation Agent minus (y) the actual Payment Amount calculated for such early termination or cancellation (in each case, with an amount that would have been owed by Counterparty expressed as a negative number for purposes of this calculation).
Settlement Price:		The average of the VWAP Prices for the Exchange Business Days in the Settlement Valuation Period, subject to Valuation Disruption as specified in the Master Confirmation.

Settlement Valuation Period:		A number of Scheduled Trading Days selected by Barclays in its reasonable discretion, beginning on the Scheduled Trading Day immediately following the Termination Date, or in the case of a Second Settlement, the date of the Friendly Transaction Announcement.

3.		Counterparty may only deliver Registered Settlement Shares pursuant to paragraph 2 above if:
		(a) a registration statement covering public resale of the Registered Settlement Shares by Barclays. (the “Registration Statement”) shall have been filed with, and declared effective by, the Securities and Exchange Commission under the Securities Act on or prior to the date of delivery, and no stop order shall be in effect with respect to the Registration Statement; a printed prospectus relating to the Registered Settlement Shares (including any prospectus supplement thereto, the “Prospectus”) shall have been delivered to Barclays, in such quantities as Barclays shall reasonably have requested, on or prior to the date of delivery;
		(b) the form and content of the Registration Statement and the Prospectus (including, without limitation, any sections describing the plan of distribution) shall be satisfactory to Barclays;
		(c) as of or prior to the date of delivery, Barclays and its agents shall have been afforded a reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities and the results of such investigation are satisfactory to Barclays, in its discretion; and
		(d) as of the date of delivery, an agreement (the “Underwriting Agreement”) shall have been entered into with Barclays in connection with the public resale of the Registered Settlement Shares by Barclays substantially similar to underwriting agreements customary for underwritten offerings of equity securities, in form and substance satisfactory to Barclays, which Underwriting Agreement shall include, without limitation, provisions substantially similar to those contained in such underwriting agreements

4.		If Counterparty delivers Unregistered Settlement Shares pursuant to paragraph 2 above:

		(c) as of the date of delivery, Counterparty shall enter into an agreement (a “Private Placement Agreement”) with Barclays (or any affiliate of Barclays designated by Barclays) in connection with the private placement of such shares by Counterparty to Barclays (or any such affiliate) and the private resale of such shares by Barclays (or any such affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance commercially reasonably satisfactory to Barclays, which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements relating to the indemnification of, and contribution in connection with the liability of, Barclays and its affiliates, and shall provide for the payment by Counterparty of all fees and expenses in connection with such resale, including all fees and expenses of counsel for Barclays, and shall contain representations, warranties and agreements of Counterparty reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales.

If the proceeds of any sale(s) made by Barclays, the Selling Agent or any underwriter(s), net of any fees and commissions (including, without limitation, underwriting or placement fees) customary for similar transactions under the circumstances at the time of the offering, together with carrying charges and expenses incurred in connection with the offer and sale of the Shares (including, but without limitation to, the covering of any over-allotment or short position (syndicate or otherwise)) (the “Net Proceeds”) exceed the absolute value of the Forward Cash Settlement Amount, Barclays will refund, in U.S. Dollars, such excess to Counterparty on the date that is three (3) Business Days following the Final Resale Date, and, if any portion of the Settlement Shares remains unsold, Barclays shall return to Counterparty on that date such unsold Shares.
6.		If the Calculation Agent determines that the Net Proceeds received from the sale of the Registered Settlement Shares or Unregistered Settlement Shares or any Make whole Shares, if any, pursuant to this paragraph 6 are less than the absolute value of the Forward Cash Settlement Amount (the amount in U.S. Dollars by which the Net Proceeds are less

		than the absolute value of the Forward Cash Settlement Amount being the “Shortfall” and the date on which such determination is made, the (“Deficiency Determination Date”), Counterparty shall on the Exchange Business Day next succeeding the Deficiency Determination Date (the “Makewhole Notice Date”) deliver to Barclays, through the Selling Agent, a notice of Counterparty’s election that is one (1) New York Business Day after the Makewhole Notice Date, or (ii) deliver additional Shares. If Counterparty elects to deliver to Barclays additional Shares, then Counterparty shall deliver additional Shares in compliance with the terms and conditions of paragraph 3 or paragraph 4 above, as the case may be (the “Makewhole Shares”), on the first Clearance System Business Day which is also an Exchange Business Day following the Makewhole Notice Date in such number as the Calculation Agent reasonably believes would have a market value on that Exchange Business Day equal to the Shortfall. Such Makewhole Shares shall be sold by Barclays in accordance with the provisions above; provided that if the sum of the Net Proceeds from the sale of the originally delivered Shares and the Net Proceeds from the sale of any Makewhole Shares is less than the absolute value of the Forward Cash Settlement Amount then Counterparty shall, at its election, either make such cash payment or deliver to Barclays further Makewhole Shares until such Shortfall has been reduced to zero.
7.		Notwithstanding the foregoing, in no event shall the aggregate number of Settlement Shares and Makewhole Shares be greater than the Reserved Shares minus the amount of any Shares actually delivered by Counterparty under any other Transaction(s) under this Master Confirmation (the result of such calculation, the “Capped Number”). Counterparty represents and warrants (which shall be deemed to be repeated on each day that a Transaction is outstanding) that the Capped Number is equal to or less than the number of Shares determined according to the following formula:

A-B

Where A = the number of authorized but unissued shares of the Counterparty that are not reserved for future issuance on the date of the determination of the Capped Number; and

B = the maximum number of Shares required to be delivered to third parties if Counterparty elected Net Share Settlement of all transactions in the Shares (other than Transactions in the Shares under this Master Confirmation) with all third parties that are then currently outstanding and unexercised.

“Reserved Shares” means initially, 3,000,000 Shares. The Reserved Shares may be increased or decreased in a Supplemental Confirmation.
