Each of the Company and the Forward Seller hereby confirm their respective agreements with the Underwriter and the Forward Purchaser concerning the purchase and sale of the Shares, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-269966), including a prospectus, relating to certain securities (the “Shelf Securities”), including the Shares, to be issued from time to time by the Company. The registration statement as amended to the date of this Agreement, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or Rule 430B under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Registration Statement,” and the related prospectus covering the Shelf Securities dated February 23, 2023 is hereinafter referred to as the “Basic Prospectus.” The Basic Prospectus, as supplemented by the prospectus supplement specifically relating to the Shares in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriter by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Prospectus,” and the term “preliminary prospectus” means any preliminary form of the Prospectus including the preliminary prospectus supplement relating to the Shares dated September 11, 2023 (the “Preliminary Prospectus”). For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act. As used herein, the terms “Registration Statement,” “Basic Prospectus,” “preliminary prospectus,” “Pricing Disclosure Package” (as defined below) and “Prospectus” shall include the documents, if any, incorporated by reference therein as of the Applicable Time (as defined below). The terms “supplement,” “amendment,” and “amend” as used herein with respect to the Registration Statement, the Basic Prospectus, the Pricing Disclosure Package, any preliminary prospectus or the Prospectus shall include all documents filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are deemed to be incorporated by reference therein after the Applicable Time.

At or prior to 6:00 p.m., New York City time, on September 11, 2023, the time when sales of the Shares were first made (the “Applicable Time”), the Company had prepared the following information (collectively, the “Pricing Disclosure Package”): (i) the Preliminary Prospectus dated September 11, 2023, (ii) any free-writing prospectus listed on Schedule 3 hereto, and (iii) the information set forth on Schedule 2 hereto.

2. Purchase and Sale of the Shares by the Underwriter and the Forward Sale.

(a) The Company understands that the Underwriter intends to make a public offering of the Shares as soon after the effectiveness of this Agreement as in the judgment of the Underwriter is advisable, and initially to offer the Shares on the terms set forth in the Pricing Disclosure Package. The Company acknowledges and agrees that the Underwriter may offer and sell the Shares to or through any affiliate of the Underwriter.

(b) On the basis of the representations and warranties herein contained, and subject to the terms and conditions herein set forth:

(i) the Forward Seller agrees to sell to the Underwriter, and the Underwriter shall purchase from the Forward Seller at a price per share of $73.67 (the “Purchase Price”) that number of Forward Underwritten Shares set forth on Schedule 1 opposite the name of the Underwriter;

(ii) the Company agrees to sell to the Underwriter, and the Underwriter shall purchase from the Company at the Purchase Price, the Company Top-Up Underwritten Shares, if any;

(iii) the Company hereby grants to the Underwriter the right to purchase at its election up to 180,000 Option Shares at the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Firm Shares but not payable on the Option Shares (the “Option Purchase Price”). Any such election to purchase Option Shares may be exercised in whole or in part at one or more times only by written notice from the Underwriter to the Company (each, an “Option Notice”), given within a period of 30 calendar days after the date of this Agreement, setting forth the aggregate number of Option Shares as to which the Underwriter is then exercising the option and the time and date on which such Option Shares are to be delivered, as determined by the Underwriter but in no event earlier than the Initial Closing Date (as defined herein) or, unless the Underwriter and the Company otherwise agree in writing, earlier than two or later than ten business days after the date of such Option Notice. The Company may, in its sole discretion, within one business day after such Option Notice is given, execute and deliver to the Forward Seller an additional letter agreement substantially in the form attached hereto as Annex A between the Company and the Forward Purchaser (each, an “Additional Forward Sale Agreement”) providing for the forward sale by the Company, subject to the terms and conditions of such Additional Forward Sale Agreement, including the Company’s right to elect Cash Settlement or Net Share Settlement (as such terms are defined in such Additional Forward Sale Agreement), of a number of shares of Common Stock equal to the aggregate number of Option Shares being purchased by the Underwriter pursuant to such exercise of the option described in this Section 2(b). Upon the Company’s execution and delivery to the Forward Seller of any Additional Forward Sale Agreement, the Forward Purchaser shall promptly execute and deliver such Additional Forward Sale Agreement to the Company.

(c) If with respect to the Forward Underwritten Shares underlying the Forward Sale Agreement (i) any of the conditions to effectiveness of the Forward Sale Agreement set forth therein have not been satisfied at the Initial Closing Date, (ii) the Company has not performed all of the obligations required to be performed by it under this Agreement on or prior to the Initial Closing Date or (iii) any of the conditions set forth in Section 7 hereof have not been satisfied on or prior to the Initial Closing Date (clauses (i) through (iii) of this Section 2(c), together, the “Conditions”), the Forward Seller, in its sole discretion, may elect not to borrow and deliver for sale to the Underwriter such Forward Underwritten Shares otherwise deliverable by the Forward Seller hereunder. In addition, if in the Forward Purchaser’s good faith and commercially reasonable judgment, (A) on or prior to 9:00 a.m. New York City time on the Initial Closing Date, the Forward Seller is unable to borrow and deliver for sale under this Agreement the full number of shares of Common Stock equal to the number of Forward Underwritten Shares otherwise deliverable by the Forward Seller or (B) either it is impracticable to do so or the Forward Seller would incur a Stock Loan Fee (as defined under the Forward Sale Agreement) of more than a rate equal to 25 basis points per annum to do so, then the Forward Seller shall only be required to deliver for sale to the Underwriter at the Initial Closing Date the aggregate number of shares of Common Stock that the Forward Seller is able to so borrow at or below such Stock Loan Fee, which, for the avoidance of doubt, may be zero.

(d) If the Company has entered into an Additional Forward Sale Agreement with the Forward Purchaser pursuant to Section 2(b)(iii) hereof, and if with respect to the Forward Option Shares underlying such Additional Forward Sale Agreement (i) any of the conditions to effectiveness of such Additional Forward Sale Agreement set forth therein have not been satisfied at the related Option Closing Date, (ii) the Company has not performed all of the obligations required to be performed by it under this Agreement on or prior to such Option Closing Date or (iii) any of the conditions set forth in Section 7 hereof have not been satisfied on or prior to such Option Closing Date (clauses (i) through (iii) of this Section 2(d), together, the “Additional Conditions”), the Forward Seller, in its sole discretion, may elect not to borrow and deliver for sale to the Underwriter such Forward Option Shares otherwise deliverable by the Forward Seller hereunder. In addition, if in the Forward Purchaser’s good faith and commercially reasonable judgment, (A) on or prior to 9:00 a.m. New York City time on the Option Closing Date, the Forward Seller is unable to borrow and deliver for sale under this Agreement the full number of shares of Common Stock equal to the number of Forward Option Shares otherwise deliverable by the Forward Seller or (B) either it is impracticable to do so or the Forward Seller would incur a Stock Loan Fee (as defined under the relevant Additional Forward Sale Agreement) of more than a rate equal to 25 basis points per annum to do so, then the Forward Seller shall only be required to deliver for sale to the Underwriter at such Option Closing Date the aggregate number of shares of Common Stock that the Forward Seller is able to so borrow at or below such Stock Loan Fee, which, for the avoidance of doubt, may be zero.

(e) If the Forward Seller elects pursuant to Section 2(c) or 2(d) hereof (in the event that the Forward Purchaser has entered into an Additional Forward Sale Agreement with the Company pursuant to Section 2(b)(iii) hereof) not to borrow and deliver for sale to the Underwriter at the applicable Closing Date the total number of Forward Underwritten Shares or Forward Option Shares, respectively, otherwise deliverable by it hereunder, then the Forward Seller shall notify the Company no later than 5:00 p.m., New York City time, on the business day immediately preceding such Closing Date.

8. Indemnification and Contribution.

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless the Underwriter, the Forward Seller and the Forward Purchaser and each of their respective affiliates, directors and officers and each person, if any, who controls the Underwriter, the Forward Seller or the Forward Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Pricing Disclosure Package, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any Underwriter Information.

(b) Indemnification by the Underwriter. The Underwriter agrees to indemnify and hold harmless the Company, the Forward Seller and the Forward Purchaser and each of their respective directors and officers and each person, if any, who controls the Company, the Forward Seller or the Forward Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) immediately above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to the Underwriter furnished to the Company in writing by the Underwriter expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Pricing Disclosure Package, it being understood and agreed that the only such information consists of the following statements in the Preliminary Prospectus and the Prospectus (collectively, the “Underwriter Information”): the information relating to stabilizing transactions and short sales in the eighteenth and nineteenth paragraphs, in each case, appearing under the heading “Underwriting (Conflicts of Interest)” in the Pricing Disclosure Package and Prospectus.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 8 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person, and the Indemnified Person shall have reasonably concluded that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for the Underwriter, the Forward Seller, the Forward Purchaser, or any of their respective affiliates, directors and officers and any control persons of the Underwriter, the Forward Seller or the Forward Purchaser shall be designated in writing by the Underwriter, the Forward Seller or the Forward Purchaser, as applicable, and any such separate firm for the Company, its directors and officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person 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, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or

judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraph (a) or (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person 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 (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person on the one hand and the Indemnified Person on the other from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Indemnifying Person on the one hand and the Indemnified Person on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Underwriter, the Forward Seller and the Forward Purchaser shall be deemed to be in the same proportion as (A) in the case of the Company, the net proceeds from the offering of the Shares (before deducting expenses) received by the Company (which proceeds shall include the proceeds to be received by the Company pursuant to the Forward Sale Agreement and any Additional Forward Sale Agreement, assuming, in each case, Physical Settlement (as defined therein) on the Effective Date (as defined therein)), (B) in the case of the Underwriter, the difference between (x) the aggregate price to the public received by the Underwriter from the sale of the Shares and (y) the aggregate price paid by the Underwriter for the Shares pursuant to this Agreement, and (C) in the case of the Forward Seller and the Forward Purchaser, the aggregate Spread (as defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable) received by the Forward Purchaser under the Forward Sale Agreement and any Additional Forward Sale Agreement, net of any costs associated therewith, as reasonably determined by the Forward Seller, bear to the aggregate offering price of the Shares as set forth in the Prospectus, plus such Spread (net of such costs). The relative fault of the Company on the one hand and the Underwriter, the Forward Seller and the Forward Purchaser on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriter, the Forward Seller and the Forward Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company, the Underwriter, the Forward Seller and the Forward Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriter, the Forward Purchaser and/or the Forward Seller were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 8, in no event shall the Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by the Underwriter with respect to the offering of the Shares exceeds the amount of any damages that the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and, in no event shall the Forward Seller and/or the Forward Purchaser be

required to contribute any amount in excess of the amount by which the aggregate Spread under the Forward Sale Agreement or any Additional Forward Sale Agreement, as the case may be, net of any costs associated therewith, as reasonably determined by the Forward Seller or Forward Purchaser, as the case may be, exceeds the amount of any damages that such Forward Seller or Forward Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

9. Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.

10. Termination. This Agreement may be terminated in the absolute discretion of the Underwriter, the Forward Seller or the Forward Purchaser by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the applicable Closing Date (i) trading generally shall have been suspended or materially limited on the Exchange; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Underwriter, the Forward Seller or the Forward Purchaser is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

Dear Sirs,

The purpose of this letter agreement (this “Forward Confirmation”) is to confirm the terms and conditions of the transaction entered into between Party A and Party B on the Trade Date specified below (the “Transaction”). This Forward Confirmation constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below.

(“ISDA”), are incorporated into this Forward Confirmation. In the event of any inconsistency among the Agreement, this Forward Confirmation, the 2006 Definitions and the 2002 Definitions, the following will prevail in the order of precedence indicated: (i) this Forward Confirmation; (ii) the 2002 Definitions; (iii) the 2006 Definitions; and (iv) the Agreement.

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.

³	To be the same as the base deal.


		Maturity Date) is not a Clearance System Business Day, such Settlement Date shall be the immediately succeeding Clearance System Business Day, (y) if Cash Settlement or Net Share Settlement applies and Party A shall have fully unwound its hedge in respect of the Transaction (or portion thereof, as applicable) during an Unwind Period (as defined below) by a date that is more than two Scheduled Trading Days prior to such Settlement Date specified above, Party A may, by written notice to Party B, specify any Scheduled Trading Day prior to such originally specified Settlement Date as the Settlement Date, and (z) Party B may not deliver a Settlement Notice to Party A for which Physical Settlement or Net Share Settlement applies if the Settlement Date specified in such Settlement Notice is scheduled to occur prior to the earlier of (1) the date on which the Underwriter (as defined in the Underwriting Agreement) has sold all of the Forward Option Shares (as defined in the Underwriting Agreement) pursuant to the Registration Statement (as defined in the Underwriting Agreement) with delivery of the Prospectus (as defined in the Underwriting Agreement) to the purchaser(s) thereof and (2) the date that is 30 days following the Effective Date.

Settlement Shares:		With respect to any Settlement Date, a number of Shares, not to exceed the Base Amount, designated as such by Party B in the related Settlement Notice or by Party A pursuant to “Termination Settlement” below; provided that on the Maturity Date the number of Settlement Shares shall be equal to the Base Amount on such date.

Settlement:		Physical Settlement, Cash Settlement or Net Share Settlement, at the election of Party B as set forth in a Settlement Notice delivered on or after the Effective Date that satisfies the Settlement Notice Requirements; provided that Physical Settlement shall apply (i) if no Settlement Method is validly selected, (ii) with respect to any Settlement Shares in respect of which Party A is unable, in its good faith, commercially reasonable judgment, to unwind its hedge in respect of the Transaction (or portion thereof, as applicable) by the end of the Unwind Period in a manner that, in the good faith, reasonable judgment of Party A, is consistent with the requirements for qualifying for the safe harbor provided by Rule 10b-18 under the Exchange Act or due to the lack of sufficient liquidity in the Shares on any Exchange Business Day during the Unwind Period or (iii) to any Termination Settlement Date (as defined below under “Termination Settlement”).

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.

		The parties hereto acknowledge and agree that they have entered into a substantially identical forward transaction with respect to [Insert number of Shares underlying Base Confirmation] Shares pursuant to a confirmation dated as of [Insert Trade Date for Base Confirmation] (the “Base Confirmation”). Party A and Party B agree that if Party B designates a Settlement Date under the Base Confirmation and for which Cash Settlement or Net Share Settlement is applicable, and the resulting Unwind Period under the Base Confirmation coincides for any period of time with an Unwind Period for the Transaction (the “Matching Unwind Period”), then the Unwind Period under this Forward Confirmation shall not commence (or, if the Unwind Period under this Forward Confirmation has already commenced, such Unwind Period shall be suspended) until the Exchange Business Day immediately following the later of (i) the date Party A actually completes the unwind of its hedge with respect to the Base Confirmation in connection with the designation of such Settlement Date under the Base Confirmation, and (ii) the date the Matching Unwind Period ends.

Suspension Day:		Any Exchange Business Day on which Party A 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 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.

Cash Settlement Amount:		For any Settlement Date in respect of which Cash Settlement applies, an amount determined by the Calculation Agent equal to the difference between (1) the product of (i) (A) the average Forward Price over the period beginning on, and including, the date that is one Settlement Cycle following the first day of the applicable Unwind Period and ending on, and including, such Settlement Date (calculated assuming no reduction to the Forward Price for any Forward Price Reduction Date that occurs during the Unwind Period, except as set forth in clause (2) below), minus USD 0.03, minus (B) the average of the 10b-18 VWAP prices per Share on each Exchange Business Day during such Unwind Period multiplied by (ii) the number of Settlement Shares for such Settlement Date and (2) the product of (i) the Forward Price Reduction Amount for any Forward Price Reduction Date that occurs during such Unwind Period multiplied by (ii) the number of Settlement Shares with respect to which Party A has not unwound its hedge as of such Forward Price Reduction 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) negative number, Party A shall deliver a number of Shares to Party B equal to the absolute value of the Net Share Settlement Shares, or (ii) positive number, Party B shall deliver


		to Party A 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 (a) the number of Settlement Shares for such Settlement Date, minus (b) the number of Shares Party A actually purchases during the Unwind Period for a total purchase price (the “Net Share Settlement Purchase Price”) equal to the difference between (1) the product of (i) the average Forward Price over the period beginning on, and including, the date that is one Settlement Cycle following the first day of the applicable Unwind Period and ending on, and including, such Settlement Date (calculated assuming no reduction to the Forward Price for any Forward Price Reduction Date that occurs during such Unwind Period, except as set forth in clause (2) below), minus USD 0.02, multiplied by (ii) the number of Settlement Shares for the Transaction for such Settlement Date, minus (2) the product of (i) the Forward Price Reduction Amount for any Forward Price Reduction Date that occurs during such Unwind Period, multiplied by (ii) the number of Shares with respect to which Party A has not unwound its hedge as of such Forward Price Reduction Date.

10b-18 VWAP:		For any Exchange Business Day during an Unwind Period that is not a Suspension Day, the volume-weighted average price at which the Shares trade as reported in the composite transactions for the Exchange on such Exchange Business Day, excluding (i) trades that do not settle regular way, (ii) opening (regular way) reported trades on the Exchange on such Exchange Business Day, (iii) trades that occur in the last ten minutes before the scheduled close of trading on the Exchange on such Exchange Business Day and ten minutes before the scheduled close of the primary trading session in the market where the trade is effected and (iv) trades on such Exchange Business Day that do not satisfy the requirements of Rule 10b-18(b)(3), as determined in good faith by the Calculation Agent. Party B acknowledges that Party A may refer to the Bloomberg Page “OGS <Equity> AQR SEC” (or any successor thereto), in its discretion, for such Exchange Business Day to determine the 10b-18 VWAP.

(h)

Party B will not engage in any “distribution” (as defined in Regulation M under the Exchange Act (“Regulation M”)) that would cause a “restricted period” (as defined in Regulation M) to occur during any Unwind Period for the Transaction.

Party B is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended).

(j)

In addition to any other requirements set forth herein, Party B agrees not to elect Cash Settlement or Net Share Settlement if, in the good faith, reasonable judgment of either Party A or Party B, such settlement or Party A’s related market activity would result in a violation of the U.S. federal securities laws or any other federal or state law or regulation applicable to Party B.

(k)

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

Party A shall make its own determination as to whether, when or in what manner any hedging or market activities in Party B’s securities shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Forward Price for the Transaction and the 10b-18 VWAP for the Transaction;

(iv)

any market activities of Party A and its affiliates with respect to the Shares may affect the market price and volatility of the Shares, as well as the Forward Price and 10b-18 VWAP, each in a manner that may be adverse to Party B; and

(o)

Party B is not in possession of any material non-public information with respect to Party B or the Shares.

Covenant of Party B:

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.

(c)

Party A hereby represents and warrants to Party B that it has implemented policies and procedures, taking into consideration the nature of its business, reasonably designed to ensure that individuals conducting hedging activity related to the Transaction do not have access to material non-public information regarding the Issuer or the Shares.

Insolvency Filing:

Notwithstanding anything to the contrary herein, in the Agreement or in the Definitions, upon any Insolvency Filing in respect of the Issuer, the Transaction shall automatically terminate on the date thereof without further liability of either party to this Forward Confirmation to the other party (except for any liability in respect of any breach of representation or covenant by a party under this Forward Confirmation prior to the date of such Insolvency Filing).

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 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. In the good faith, commercially reasonable judgment of Party A (i) Party A (or its affiliate) is unable to hedge Party A’s exposure to the Transaction because of the lack of sufficient Shares being made available for Share borrowing by lenders, or (ii) Party A (or its affiliate) would incur a Stock Loan Fee to borrow a number of Shares equal to the Base Amount of more than a rate equal to 200 basis points per annum (each, a “Stock Borrow Event”);

(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;

(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).

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 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, but Party A may not otherwise determine that the Settlement Shares are Restricted Shares based solely upon Party A (or its affiliates) not having borrowed a number of Shares equal to the Base Amount on or before the Effective Date if there has been no change in law or change in the policy of the Securities and Exchange Commission or its staff.

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”).⁴

⁴	This number should not exceed 19.9% of total Shares outstanding on the Trade Date (calculated on an aggregate basis for all Forwards).

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 without the prior written consent of Party B. Notwithstanding any other provision in this 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 expenses (including reasonable 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 or willful misconduct.

4.	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, and after taking into account any Shares or any other class of voting securities of Party B concurrently deliverable to Party A pursuant to the Base Confirmation, (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 (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, and after taking into account any Shares or any other class of voting securities of Party B concurrently deliverable to Party A pursuant to the Base Confirmation, (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, and after taking into account any Shares or any other class of voting securities of Party B concurrently deliverable to Party A pursuant to the Base Confirmation, (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.

⁵	Insert a number of Shares equal to 4.9% of the outstanding Shares on the date on which the Transaction is executed.

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)).

ANNEX A

PRIVATE PLACEMENT PROCEDURES

(i)

If Party B delivers the Restricted Shares pursuant to this clause (i) (a “Private Placement Settlement”), then delivery of Restricted Shares by Party B shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Party A; provided that if, on or before the date that a Private Placement Settlement would occur, Party B has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(a)(2) of the Securities Act for the sale by Party B to Party A (or any affiliate designated by Party A) of the Restricted Shares or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Party A (or any such affiliate of Party A) or Party B fails to deliver the Restricted Shares when due or otherwise fails to perform obligations within its control in respect of a Private Placement Settlement, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Party A, due diligence rights (for Party A or any designated buyer of the Restricted Shares by Party A), opinions and certificates, and such other documentation as is customary for private placement agreements, all reasonably acceptable to Party A. In the case of a Private Placement Settlement, Party A shall, in its good faith discretion, adjust the number of Restricted Shares to be delivered to Party A hereunder and/or the Forward Price in a commercially reasonable manner to reflect the fact that such Restricted Shares may not be freely returned to securities lenders by Party A and may only be saleable by Party A at a discount to reflect the lack of liquidity in Restricted Shares. Notwithstanding the Agreement, this Forward Confirmation, the date of delivery of such Restricted Shares shall be the Clearance System Business Day following notice by Party A to Party B of 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 Settlement Date or Termination Settlement Date that would otherwise be applicable.

(ii)

If Party B delivers any Restricted Shares in respect of the Transaction, Party B agrees that (i) such Shares may be transferred by and among Party A and its affiliates and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after the applicable Settlement Date, Party B shall promptly remove, or cause the transfer agent for the Shares to remove, any legends referring to any transfer restrictions from such Shares upon delivery by Party A (or such affiliate of Party A) to Party B or such transfer agent of seller’s and broker’s representation letters customarily delivered by Party A or its affiliates in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, each without any further 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 Party A (or such affiliate of Party A).
