This Forward Confirmation together with the Agreement shall evidence a complete and binding agreement between Party A and Party B as to the subject matter and terms of the Transaction to which this Forward Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

The parties hereby agree that no transaction other than the Transaction to which this Forward Confirmation relates shall be governed by the Agreement. For purposes of the 2002 Definitions, the Transaction shall be a Share Forward Transaction.

Party A and Party B each represents to the other that it has entered into the Transaction in reliance upon such tax, accounting, regulatory, legal, and financial advice as it deems necessary and not upon any view expressed by the other.

Settlement Notice
Requirements:
	Notwithstanding any other provision hereof, a Settlement Notice delivered by Party B that specifies Cash Settlement or Net Share Settlement will not be effective to establish a Settlement Date or require Cash Settlement or Net Share Settlement unless Party B delivers to Party A with such Settlement Notice a representation signed by Party B substantially in the following form: “As of the date of this Settlement Notice, Party B is not aware of any material nonpublic information concerning itself or the Shares, and is designating the date contained herein as a Settlement Date and is electing Cash Settlement or Net Share Settlement, as the case may be, in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws.”

Unwind Period:	Each Exchange Business Day that is not a Suspension Day during the period from and including the first Exchange Business Day following the date Party B validly elects Cash Settlement or Net Share Settlement in respect of a Settlement Date through the second Scheduled Trading Day preceding such Settlement Date (or the immediately preceding Exchange Business Day if such Scheduled Trading Day is not an Exchange Business Day), subject to “Termination Settlement” below. If any Exchange Business Day during an Unwind Period is a Disrupted Day, the Calculation Agent shall make commercially reasonable adjustments to the terms of the Transaction (including, without limitation, the Cash Settlement Amount, the number of Net Share Settlement Shares and the 10b-18 VWAP) to account for the occurrence of such Disrupted Day.

Suspension Day:	Any Exchange Business Day on which Party A reasonably determines based on the advice of counsel that Cash Settlement or Net Share Settlement may violate applicable securities laws. Party A shall notify Party B if it receives such advice from its counsel.

Market Disruption Event:	Section 6.3(a)(ii) of the 2002 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 reasonably determines is material.”

Exchange Act:	The Securities Exchange Act of 1934, as amended from time to time.

Physical Settlement:	On any Settlement Date in respect of which Physical Settlement applies, Party B shall deliver to Party A through the Clearance System the Settlement Shares for such Settlement Date, and Party A shall deliver to Party B, by wire transfer of immediately available funds to an account designated by Party B, an amount in cash equal to the Physical Settlement Amount for such Settlement Date, on a delivery versus payment basis. If, on any Settlement Date, the Shares to be delivered by Party B to Party A hereunder upon Physical Settlement are not so delivered (the “Physical Deferred Shares”), and a Forward Price Reduction Date with respect to the Transaction occurs during the period from, and including, such Settlement Date to, but excluding, the date such Shares are actually delivered to Party A, then the portion of the Physical Settlement Amount payable by Party A to Party B in respect of the Physical Deferred Shares shall be reduced by an amount equal to (1) the Forward Price Reduction Amount for such Forward Price Reduction Date multiplied by (2) the number of Physical Deferred Shares.

Physical Settlement Amount:	For any Settlement Date in respect of which Physical Settlement applies, an amount in cash equal to the product of (i) the Forward Price on such Settlement Date and (ii) the number of Settlement Shares for such Settlement Date.

Cash Settlement:	On any Settlement Date in respect of which Cash Settlement applies, if the Cash Settlement Amount for such Settlement Date is a positive number, Party A will pay such Cash Settlement Amount to Party B. If the Cash Settlement Amount is a negative number, Party B will pay the absolute value of such Cash Settlement Amount to Party A. Such amounts shall be paid on the relevant Settlement Date.

Net Share Settlement:	On any Settlement Date in respect of which Net Share Settlement applies, if the number of Net Share Settlement Shares is a (i) positive number, Party A shall deliver to Party B the Net Share Settlement Shares, or (ii) negative number, Party B shall deliver a number of Shares to Party A equal to the absolute value of the Net Share Settlement Shares; provided that if Party A determines in its good faith, commercially reasonable judgment that it would be required to deliver Net Share Settlement Shares to Party B, Party A may elect to deliver a portion of such Net Share Settlement Shares on one or more dates prior to the applicable Settlement Date. If, on any Settlement Date, the Shares to be delivered by Party B or Party A hereunder upon Net Share Settlement are not so delivered (the “Net Share Deferred Shares”), and a Forward Price Reduction Date occurs during the period from, and including, such Settlement Date to, but excluding, the date such Shares are actually delivered to such party, then the portion of the Net Share Settlement Shares deliverable by Party A or Party B in respect of the Net Share Deferred Shares shall be adjusted by the Calculation Agent to reflect the occurrence of such Forward Price Reduction Amount for such Forward Price Reduction Date.

Net Share Settlement Shares:	For any Settlement Date in respect of which Net Share Settlement applies, a number of Shares equal to (i) the Cash Settlement Amount divided by (ii) the Average Unwind Period 10b-18 VWAP, with the number of Shares rounded up in the event such calculation results in a fractional number of Shares.

10b-18 VWAP:	For any Exchange Business Day during an Unwind Period that is not a Suspension Day, a price per Share equal to the Rule 10b-18 volume-weighted average price per Share as reported in the composite transactions for the Exchange 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 L.P. or its successor at 4:15 ▇.▇.▇▇▇ York time (or 15 minutes following the end of any extension of the regular trading session) on such Exchange Business Day, on Bloomberg page“PNW <Equity> AQR SEC” (or any successor thereto), or if such price is not so reported on such Exchange Business Day for any reason or is, in the Calculation Agent’s reasonable determination, erroneous, such 10b-18 VWAP shall be as determined by the Calculation Agent in good faith and in a commercially reasonable manner including only those trades that are reported during the period of time during which Party B could purchase its own shares under Rule 10b-18(b)(2)and effected pursuant to the conditions of Rule 10b-18(b)(3), each under the Exchange Act.

Covenant of Party B:

Subject to the provisions of “Private Placement Procedures” below, the parties acknowledge and agree that any Shares delivered by Party B to Party A on any Settlement Date will be newly issued Shares and when delivered by Party A (or an affiliate of Party A) to securities lenders from whom Party A (or an affiliate of Party A) borrowed Shares in connection with hedging its exposure to the Transaction will be freely saleable without further registration or other restrictions under the Securities Act, in the hands of those securities lenders, irrespective of whether such stock loan is effected by Party A or an affiliate of Party A. Accordingly, subject to the provisions of “Private Placement Procedures” below, Party B agrees that the Shares that it delivers to Party A on each Settlement Date will not bear a restrictive legend and that such Shares will be deposited in, and the delivery thereof shall be effected through the facilities of, the Clearance System.

Covenants of Party A:

(a)

Unless the provisions set forth below under “Private Placement Procedures” shall be applicable, Party A shall use any Shares delivered by Party B to Party A on any Settlement Date to return to securities lenders to close out open Share loans created by Party A or an affiliate of Party A in the course of Party A’s or such affiliate’s hedging activities related to Party A’s exposure under this Forward Confirmation.

(b)

In connection with bids and purchases of Shares in connection with any Cash Settlement or Net Share Settlement of the Transaction, Party A shall use its commercially reasonable efforts to conduct its activities, or cause its affiliates to conduct their activities, in a manner consistent with the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act, as if such provisions were applicable to such purchases.

Extraordinary Dividends:

If an ex-dividend date for an Extraordinary Dividend occurs on or after the Trade Date and on or prior to the Maturity Date (or, if later, the last date on which Shares are delivered by Party B to Party A in settlement of the Transaction), Party B shall pay an amount, as determined by the Calculation Agent in a commercially reasonable manner, in cash equal to the product of (1) such Extraordinary Dividend and (2) the Base Amount to Party A on the earlier of (i) the date on which such Extraordinary Dividend is paid by the Issuer to holders of record of the Shares or (ii) the Maturity Date. “Extraordinary Dividend” means the per Share amount of any cash dividend or distribution, or a portion thereof, declared by the Issuer with respect to the Shares that is specified by the board of directors of the Issuer as an “extraordinary” dividend.

Acceleration Events:

The following events shall each constitute an “Acceleration Event”:

(a)

Stock Borrow Events.

(b)

Dividends and Other Distributions. On any day occurring after the Trade Date, Party B declares a distribution, issue or dividend to existing holders of the Shares of (i) any cash dividend (other than an Extraordinary Dividend) to the extent all cash dividends having an ex-dividend date during the period from, and including, any Forward Price Reduction Date (with the Trade Date being a Forward Price Reduction Date for purposes of this clause (b) only) to, but excluding, the next subsequent Forward Price Reduction Date exceeds, on a per Share basis, the Forward Price Reduction Amount set forth opposite the first date of any such period on Schedule I, (ii) share capital or securities of another issuer acquired or owned (directly or indirectly) by Party B as a result of a spin-off or other similar transaction or (iii) any other type of securities (other than Shares), rights or warrants or other assets, for payment (cash or other consideration) at less than the prevailing market price as reasonably determined by Party A;

(c)

ISDA Early Termination Date. Party A has the right to designate an Early Termination Date pursuant to Section 6 of the Agreement, in which event, except as otherwise specified in this Forward Confirmation and except as a result of an Event of Default under Section 5(a)(i) of the Agreement, the provisions specified under “Termination Settlement” below shall apply in lieu of the consequences specified in Section 6 of the Agreement;

	(d)	Other ISDA Events. The announcement of any event that if consummated, would result in an Extraordinary Event or the occurrence of any Change in Law or a Delisting; provided that in case of a Delisting, in addition to the provisions of Section 12.6(a)(iii) of the 2002 Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, the Nasdaq Global Select Market or the Nasdaq Global Market (or their respective successors); and provided further that the definition of “Change in Law” provided in Section 12.9(a)(ii) of the 2002 Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “, or public announcement of, the formal or informal interpretation”, (ii) replacing the parenthetical beginning after the word “regulation” in the second line thereof with the words “(including, for the avoidance of doubt and without limitation, (x) any tax law or (y) adoption, effectiveness or promulgation of new regulations authorized or mandated by existing statute)” and (iii) immediately following the word “Transaction” in clause (X) thereof, adding the phrase “in the manner contemplated by Party A on the Trade Date”; or

	(e)	Ownership Event. In the good faith, reasonable judgment of Party A, on any day, the Share Amount for such day exceeds the Post-Effective Limit for such day (if any applies).

Each party hereto represents and warrants to, and agrees with, the other party hereto that (i) to its knowledge, on the Trade Date, the Share Amount for such day does not exceed the Post-Effective Limit for such day and (ii) it does not know on the Trade Date of any event or circumstance that will cause the Share Amount to exceed the Post-Effective Limit on any day during the term of the Transaction; provided, however, that the foregoing representation by Party B shall (i) exclude any Shares other than the Shares subject to this Forward Confirmation or the Transaction, (ii) be deemed to exclude the reference to the determination by Party A in its reasonable discretion from the definition of “Post-Effective Limit” and (iii) exclude matters arising as a result of the regulatory status of Party A as a financial institution or broker-dealer.

The “Share Amount” as of any day is the number of Shares that Party A and any person whose ownership position would be aggregated with that of Party A, including any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part (Party A or any such person, a “Party A Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Party B that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership of under any Applicable Restriction, as determined by Party A in its reasonable discretion. The “Post-Effective Limit” means a number of Shares equal to (x) the minimum number of Shares that could reasonably be expected to give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Party A Person, or could reasonably be expected to result in an adverse effect on a Party A Person, under any Applicable Restriction, as determined by Party A in its reasonable discretion, minus (y) 1% of the number of Shares outstanding.

Termination Settlement:

Upon the occurrence of any Acceleration Event, Party A shall have the right to designate, upon at least one Scheduled Trading Day’s notice, any Scheduled Trading Day following such occurrence to be a Settlement Date hereunder (a “Termination Settlement Date”) to which Physical Settlement shall apply, and to select the number of Settlement Shares relating to such Termination Settlement Date; provided that (i) in the case of an Acceleration Event arising out of an Ownership Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares necessary to reduce the Share Amount to the Post-Effective Limit and (ii) in the case of an Acceleration Event arising out of a Stock Borrow Event the number of Settlement Shares so designated by Party A shall not exceed the number of Shares as to which such Stock Borrow Event exists. If, upon designation of a Termination Settlement Date by Party A pursuant to the preceding sentence, Party B fails to deliver the Settlement Shares relating to such Termination Settlement Date when due or otherwise fails to perform obligations within its control in respect of the Transaction, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. If an Acceleration Event occurs during an Unwind Period relating to a number of Settlement Shares to which Cash Settlement or Net Share Settlement applies, then on the Termination Settlement Date relating to such Acceleration Event, notwithstanding any election to the contrary by Party B, Cash Settlement or Net Share Settlement shall apply to the portion of the Settlement Shares relating to such Unwind Period as to which Party A has unwound its hedge and Physical Settlement shall apply in respect of (x) the remainder (if any) of such Settlement Shares and (y) the Settlement Shares designated by Party A in respect of such Termination Settlement Date. Under no circumstances will Party A be entitled to an adjustment to the terms for the effects of an Extraordinary Dividend (other than as set forth above under the heading “Extraordinary Dividends”) or a change in expected dividends. For the avoidance of doubt, the immediately preceding sentence shall not preclude or otherwise limit Party A from exercising its “Termination Settlement” rights pursuant to this paragraph upon the occurrence of an Acceleration Event as set forth in clause (b) of such definition.

Private Placement Procedures:

If Party B is unable to comply with the provisions of “Covenant of Party B” above because of a change in law or a change in the policy of the Securities and Exchange Commission or its staff, or Party A otherwise determines that in its reasonable opinion, based on advice of counsel, any Settlement Shares to be delivered to Party A by Party B may not be freely returned by Party A or its affiliates to securities lenders as described under “Covenant of Party B” above, then delivery of any such Settlement Shares (the “Restricted Shares”) shall be effected pursuant to Annex A hereto, unless waived by Party A.

Rule 10b5-1:

It is the intent of Party A and Party B that following any election of Cash Settlement or Net Share Settlement by Party B, the purchase of Shares by Party A during any Unwind Period comply with the requirements of Rule 10b5-1(c)(1)(i)(B) of the Exchange Act and that this Forward Confirmation shall be interpreted to comply with the requirements of Rule 10b5-1(c).

Party B acknowledges that (i) during any Unwind Period, Party B does not have, and shall not attempt to exercise, any influence over how, when or whether to effect purchases of Shares by Party A (or its agent or affiliate) in connection with this Forward Confirmation and (ii) Party B is entering into the Agreement and this Forward Confirmation in good faith and not as part of a plan or scheme to evade compliance with federal securities laws including, without limitation, Rule 10b-5 promulgated under the Exchange Act.

Party B hereby agrees with Party A that, during any Unwind Period, Party B shall not communicate, directly or indirectly, any Material Non-Public Information (as defined herein) to any EDG Personnel (as defined below). For purposes of the Transaction, “Material Non-Public Information” means information relating to Party B or the Shares that (a) has not been widely disseminated by wire service, in one or more newspapers of general circulation, by communication from Party B to its shareholders or in a press release, or contained in a public filing made by Party B with the Securities and Exchange Commission, or otherwise disseminated in a manner constituting “public disclosure” within the meaning of Regulation FD under the Exchange Act and (b) a reasonable investor might consider to be of importance in making an investment decision to buy, sell or hold Shares. For the avoidance of doubt and solely by way of illustration, information should be presumed “material” if it relates to such matters as dividend increases or decreases, earnings estimates, changes in previously released earnings estimates, significant expansion or curtailment of operations, a significant increase or decline of customers, significant merger or acquisition proposals or agreements, significant new supply shortages or disruptions, extraordinary borrowing, major litigation, liquidity problems, extraordinary management developments, purchase or sale of substantial assets, or other similar information. For purposes of the Transaction, “EDG Personnel” means any employee on the trading side of the Equity Derivatives Group of Party A and does not include any of Party A’s “private side” equity or equity-linked personnel (including, without limitation, any Party A equity or equity-linked legal personnel) (or any other person or persons designated from time to time in writing to Party B by Party A).

Maximum Share Delivery:

Notwithstanding any other provision of this Forward Confirmation, in no event will Party B be required to deliver on any Settlement Date, whether pursuant to Physical Settlement, Net Share Settlement, Termination Settlement or any Private Placement Settlement, more than a number of Shares equal to twice the initial Base Amount to Party A, subject to reduction by the amount of Shares delivered by Party B on any prior Settlement Date (the “Forward Shares”).

Interpretive Letter:

The parties intend for this Forward Confirmation to constitute a “Contract” as described in the letter dated October 6, 2003 submitted on behalf of ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co. to ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ of the staff of the Securities and Exchange Commission (the “Staff”) to which the Staff responded in an interpretive letter dated October 9, 2003 (the “Interpretive Letter”).

Transfer and Assignment:

Party A may assign or transfer any of its rights or delegate any of its duties hereunder to any affiliate of Party A or any entity organized or sponsored by Party A (a “Transferee”) without the prior written consent of Party B so long as (a)(i) the senior unsecured debt rating or long term issuer credit rating (as applicable, the “Credit Rating”) of such Transferee is equal to or greater than the Credit Rating of Party A, as specified by each of S&P Global Ratings and ▇▇▇▇▇’▇ Investors Service, Inc., at the time of such assignment or transfer or (ii) the obligations of such Transferee are fully, unconditionally and irrevocably guaranteed by Party A or, if Party A’s ultimate parent entity satisfies the Credit Rating requirements that would otherwise apply to a Transferee, by Party A’s ultimate parent entity; (b) Party B will not (including, for the avoidance of doubt, after giving effect to any indemnity from the transferee or assignee to Party B provided in connection with such transfer or assignment) be required to pay (including a payment in kind) to such assignee or transferee an amount in respect of an Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement greater than the amount in respect of which Party B would have been required to pay (including a payment in kind) Party A in the absence of such assignment or transfer; (c) Party B will not (including, for the avoidance of doubt, after giving effect to any indemnity from the transferee or assignee to Party B provided in connection with such transfer or assignment) receive a payment (including a payment in kind) from which an amount has been withheld or deducted on account of a Tax (after accounting for amounts paid by the transferee or assignee under Section 2(d)(i)(4) of the Agreement) in excess of that which Party A would have been required to so withhold or deduct in the absence of such assignment or transfer; (d) no Acceleration Event or other event or circumstance giving rise to a right or responsibility to terminate or cancel the Transaction will occur as a result of such assignment or transfer; and (e) such transfer does not materially and adversely affect the availability of the relief provided in the Interpretive Letter or the application thereof to such Transaction in the manner contemplated by Party B on the Trade Date. Party A agrees to give reasonable prior notice to Party B of any transfer or assignment without Party B’s consent pursuant to this paragraph. Notwithstanding any such notice, no assignment or transfer by Party A pursuant to this subparagraph shall take effect unless and until all conditions to such transfer or assignment are satisfied. Notwithstanding any other provision in this Forward Confirmation to the contrary requiring or allowing Party A to purchase, sell, receive or deliver any Shares or other securities to or from Party B, Party A may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Party A’s obligations in respect of the Transaction and any such designee may assume such obligations. Party A shall be discharged of its obligations to Party B to the extent of any such performance.

Indemnity:

Party B agrees to indemnify Party A and its affiliates and their respective directors, officers, agents and controlling parties (Party A and each such affiliate or person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, incurred by or asserted against such Indemnified Party arising out of, in connection with, or relating to, any breach of any covenant or representation made by Party B in this Forward Confirmation or the Agreement and will reimburse any Indemnified Party for all reasonable documented expenses (including reasonable documented legal fees and expenses) as they are incurred in connection with the investigation of, preparation for, or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto. Party B will not be liable under this Indemnity paragraph to the extent that any loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court to have resulted from Party A’s gross negligence, willful misconduct or bad faith, or from a breach of any representation or covenant of Party A contained in this Forward Confirmation or the Agreement.

Notice:

Non-Reliance:	Applicable

Additional Acknowledgments:	Applicable

Agreements and Acknowledgments
Regarding Hedging Activities:	Applicable

The Agreement is further supplemented by the following provisions:

No Collateral or Setoff:

Notwithstanding Section 6(f) or any other provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Party B hereunder are not secured by any collateral. Obligations under the Transaction shall not be set off against any other obligations of the parties, whether arising under the Agreement, under this Forward Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other obligations of the parties shall be set off against obligations under the Transaction, whether arising under the Agreement, under this Forward Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and each party hereby waives any such right of setoff. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement, (a) separate amounts shall be calculated as set forth in such Section 6(e) with respect to (i) the Transaction and (ii) all other Transactions and (b) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement.

Status of Claims in Bankruptcy:

Party A acknowledges and agrees that this Forward Confirmation is not intended to convey to Party A rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Party B; provided, however, that nothing herein shall limit or shall be deemed to limit Party A’s right to pursue remedies in the event of a breach by Party B of its obligations and agreements with respect to this Forward Confirmation and the Agreement; and provided further, that nothing herein shall limit or shall be deemed to limit Party A’s rights in respect of any transaction other than the Transaction.

Limit on Beneficial Ownership:

Notwithstanding any other provisions hereof, Party A shall not have an “interest” in (within the meaning of NYSE Rule 312.04(e)) Shares hereunder and Party A shall not be entitled to take delivery of any Shares deliverable hereunder (in each case, whether in connection with the purchase of Shares on any Settlement Date or any Termination Settlement Date, any Private Placement Settlement or otherwise) to the extent (but only to the extent) that, after such receipt of any Shares hereunder, (i) the Share Amount would exceed the Post-Effective Limit, (ii) the Section 16 Percentage would exceed 7.5% or (iii) Party A and each person subject to aggregation of Shares with Party A under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder (the “Party A 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 5,557,940 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, (ii) the Section 16 Percentage would exceed 7.5% or (iii) Party A Group would directly or indirectly so beneficially own in excess of the Threshold Number of Shares. If any delivery owed to Party A hereunder is not made, in whole or in part, as a result of this provision, Party B’s obligation to make such delivery shall not be extinguished and Party B shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Party A gives notice to Party B that, after such delivery, (i) the Share Amount would not exceed the Post-Effective Limit, (ii) the Section 16 Percentage would not exceed 7.5% and (iii) Party A Group would not directly or indirectly so beneficially own in excess of the Threshold Number of Shares. 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 Party A and any of its affiliates or any other person subject to aggregation with Party A for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day.

In addition, notwithstanding anything herein to the contrary, if any delivery owed to Party A hereunder is not made, in whole or in part, as a result of the immediately preceding paragraph, Party A shall be permitted to make any payment due in respect of such Shares to Party B in two or more tranches that correspond in amount to the number of Shares delivered by Party B to Party A pursuant to the immediately preceding paragraph.

Other Forward Transactions:

Party A acknowledges that Party B has entered into or may enter into one or more forward transactions on the Shares (each, an “Other Forward” and, collectively, the “Other Forwards”), with one or more other forward purchasers. Party A and Party B agree that if Party B designates a “Settlement Date” (or equivalent concept) with respect to one or more Other Forwards for which “Cash Settlement” (or equivalent concept) or “Net Share Settlement” (or equivalent concept) is applicable, and the resulting “Unwind Period” (or equivalent concept) for such Other Forward(s) coincides for any period of time with an Unwind Period for the Transaction (the “Overlap Unwind Period”), Party B shall notify Party A at least one Scheduled Trading Day prior to the commencement of such Overlap Unwind Period of the first Scheduled Trading Day and the length of such Overlap Unwind Period, and Party A shall be permitted to purchase Shares to unwind its hedge in respect of the Transaction only on alternating Scheduled Trading Days during such Overlap Unwind Period, as notified to Party A by Party B at least one Exchange Business Day prior to such Overlap Unwind Period (which alternating Scheduled Trading Days, for the avoidance of doubt, shall be every other Scheduled Trading Day if there is only one Other Forward, every third Scheduled Trading Day if there are two Other Forwards, etc.).

Wall Street Transparency and Accountability Act:

In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (the “WSTAA”), the parties hereby agree that neither the enactment of the WSTAA or any regulation under the WSTAA, nor any requirement under the WSTAA or an amendment made by the WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Forward Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Forward Confirmation, the 2002 Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from any Acceleration Event or Illegality (as defined in the Agreement)).

Severability:

If any term, provision, covenant or condition of this Forward Confirmation, or the application thereof to any party or circumstance, shall be held to be invalid or unenforceable in whole or in part for any reason, the remaining terms, provisions, covenants, and conditions hereof shall continue in full force and effect as if this Forward Confirmation had been executed with the invalid or unenforceable provision eliminated, so long as this Forward Confirmation as so modified continues to express, without material change, the original intentions of the parties as to the subject matter of this Forward Confirmation and the deletion of such portion of this Forward Confirmation will not substantially impair the respective benefits or expectations of parties to this Forward Confirmation; provided, however, that this severability provision shall not be applicable if any provision of Section 2, 5, 6 or 13 of the Agreement (or any definition or provision in Section 14 to the extent that it relates to, or is used in or in connection with any such Section) shall be so held to be invalid or unenforceable.

US QFC Stay Rules:

If Party A and Party B agree that (i) to the extent that prior to the date hereof all parties have adhered to the 2018 ISDA U.S. Resolution Stay Protocol (the “Protocol”), the terms of the Protocol are incorporated into and form a part of the Agreement, and for such purposes the Agreement shall be deemed a Protocol Covered Agreement and each party shall be deemed to have the same status as Regulated Entity and/or Adhering Party as applicable to it under the Protocol; (ii) to the extent that prior to the date hereof the parties have executed a separate agreement the effect of which is to amend the qualified financial contracts between them to conform with the requirements of the QFC Stay Rules (the “Bilateral Agreement”), the terms of the Bilateral Agreement are incorporated into and form a part of the Agreement and each party shall be deemed to have the status of “Covered Entity” or “Counterparty Entity” (or other similar term) as applicable to it under the Bilateral Agreement; or (iii) if clause (i) and clause (ii) do not apply, the terms of Section 1 and Section 2 and the related defined terms (together, the “Bilateral Terms”) of the form of bilateral template entitled “Full-Length Omnibus (for use between U.S. G-SIBs and Corporate Groups)” published by ISDA on November 2, 2018 (currently available on the 2018 ISDA U.S. Resolution Stay Protocol page at ▇▇▇.▇▇▇▇.▇▇▇ and, a copy of which is available upon request), the effect of which is to amend the qualified financial contracts between the parties thereto to conform with the requirements of the QFC Stay Rules, are hereby incorporated into and form a part of the Agreement, and for such purposes the Agreement shall be deemed a “Covered Agreement,” Party A shall be deemed “Covered Entity” and Party B shall be deemed a “Counterparty Entity.” In the event that, after the date of the Agreement, all parties hereto become adhering parties to the Protocol, the terms of the Protocol will replace the terms of this paragraph. In the event of any inconsistencies between the Agreement and the terms of the Protocol, the Bilateral Agreement or the Bilateral Terms (each, the “QFC Stay Terms”), as applicable, the QFC Stay Terms will govern.

In making this representation, it may rely on (i) the accuracy of any representations made by the other party pursuant to Section 3(f) of the Agreement; (ii) the satisfaction of the agreement contained in Section 4(a)(i) or 4(a)(iii) of the Agreement and the accuracy and effectiveness of any document provided by the other party pursuant to Section 4(a)(i) or 4(a)(iii) of the Agreement; and (iii) the satisfaction of the agreement of the other party contained in Section 4(d) of the Agreement; provided that it shall not be a breach of this representation where reliance is placed on clause (ii) and the other party does not deliver a form or document under Section 4(a)(iii) of the Agreement by reason of material prejudice to its legal or commercial position.”
