	SUBJECT:	  	Registered Forward Transactions

 The purpose of this letter agreement (this “Master Confirmation”) is to set forth the terms and
conditions of one or more transactions (each, a “Transaction”) to be entered into between [                ] (“Dealer”) and Affiliated
Managers Group, Inc. (“Counterparty”). Each such Transaction entered into between Dealer and Counterparty that is subject to this Master Confirmation shall be evidenced by (i) one or more instructions (each, an
“Instruction”) pursuant to Section 2(b) of the Distribution Agreement (as defined below) (an “Agency Forward”) or a terms agreement (the “Terms Agreement”) pursuant to Section 2(l) of the
Distribution Agreement (a “Block Forward”) and (ii) with respect to an Agency Forward, a pricing supplement substantially in the form of Annex A hereto (a “Pricing Supplement”), each with such modifications as
to which Dealer and Counterparty mutually agree. This Master Confirmation, an Instruction or a Terms Agreement and a Pricing Supplement, if any, together shall constitute a “Confirmation” for the purposes of the Agreement specified below.
This Master Confirmation, each Instruction, Terms Agreement, Pricing Supplement and the Agreement constitute the entire agreement and understanding of the parties with respect to the subject matter and terms of the Transactions and supersede all
prior or contemporaneous written and oral communications with respect thereto. 
 The definitions and provisions contained in the 2002 ISDA Equity
Derivatives Definitions (the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc., are incorporated into each Confirmation, including this Master Confirmation. For purposes of the Equity
Definitions, each Transaction will be deemed to be a Share Forward Transaction. 
 Each party is hereby advised, and each such party acknowledges, that the
other party has engaged in, or refrained from engaging in, substantial financial transactions and has taken other material actions in reliance upon the parties’ entry into the Transactions to which this Master Confirmation, each Instruction or
Terms Agreement and the Pricing Supplement, if any, relate on the terms and conditions set forth below. 

  
 1 













 This Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, evidence a
complete and binding agreement between Dealer and Counterparty as to the terms of each Transaction to which this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, relate. This Master Confirmation, each
Instruction or Terms Agreement and the Pricing Supplement, if any, together with all other Confirmations of Equity Contracts (as defined in “Netting and Set-off” below), shall supplement, form a part
of, and be subject to an agreement in the form of the ISDA 2002 Master Agreement (the “Agreement”) as if Dealer and Counterparty had executed an agreement in such form (without any Schedule except for the election of United States
dollars (“USD”) as the Termination Currency and such other elections set forth in this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any). 

If, in relation to any Transaction to which this Master Confirmation, an Instruction or a Terms Agreement, as applicable, and the Pricing Supplement, if any,
relate, there is any inconsistency between the Agreement, this Master Confirmation, such Instruction or Terms Agreement and any such Pricing Supplement and the Equity Definitions, the following will prevail for purposes of such Transaction in the
order of precedence indicated: (i) any such Pricing Supplement; (ii) such Instruction or Terms Agreement; (iii) this Master Confirmation; (iv) the Equity Definitions; and (v) the Agreement. The parties hereby agree that,
other than the Transactions to which this Master Confirmation, all Instructions or Terms Agreements and Pricing Supplements, if any, relate and any other Equity Contract, no other Transaction shall be governed by the Agreement. The parties also
acknowledge that the Transactions to which this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, relate are not governed by, and shall not be treated as Transactions under, any other ISDA Master Agreement
entered into between Dealer and Counterparty from time to time.

Net Stock Settlement applies, any Settlement Date, including a Settlement Date on the scheduled Final Date, shall be deferred until the date on which Dealer (or its affiliate) is able to completely unwind Dealer’s hedge with respect to the
portion of the Number of Shares to be settled if Dealer (or its affiliate) is unable to completely unwind Dealer’s hedge with respect to the portion of the Number of Shares to be settled during the Unwind Period due to the restrictions of Rule 10b-18 (“Rule 10b-18”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) agreed to

Rule 10b-18 Unavailability Period (as defined below), the Unwind Period with respect to the remainder of such Settlement Shares shall recommence on the next succeeding Exchange Business Day that is not a
Suspension Day and (y) in the case of a Rule 10b-18 Unavailability Period, the remainder of such Settlement Shares shall be treated as if Counterparty had not designated a Settlement Date with

applicable Number of Shares determined taking into account pending Settlement Shares for the relevant Transaction.

		
	Settlement Method Election:	  	Physical Settlement, Cash Settlement, or Net Stock Settlement, at the election of Counterparty, in its sole discretion, as set forth in a Settlement Notice; provided that if Counterparty elects Cash Settlement or Net Stock
Settlement, it shall be deemed to have repeated the representations contained under “Securities Laws Representations and Agreements” below; provided, further, that if no election is made by Counterparty, Physical Settlement shall
apply. The parties hereto acknowledge that Counterparty cannot be obligated to settle any Transaction by cash payment unless Counterparty elects Cash Settlement.
		
	Physical Settlement:	  	If Physical Settlement is applicable, then Counterparty shall deliver to Dealer through the Clearance System a number of Shares equal to the Settlement Shares for such Settlement Date, and Dealer shall pay to Counterparty, by wire
transfer of immediately available funds to an account designated by Counterparty, an amount equal to the Physical Settlement Amount for such Settlement Date.

average price (the “Unwind Purchase Price”) at which Dealer (or its affiliate) purchases Shares during the Unwind Period to 


  
 8 














			
		
		  	unwind Dealer’s hedge (or, if Net Stock Settlement applies, to unwind all or a portion of Dealer’s hedge, including any purchases of Shares for delivery to Counterparty, in each case as determined by Dealer) with respect
to the portion of the applicable Number of Shares to be settled during the Unwind Period (including, for the avoidance of doubt, purchases on any Suspension Day or Disrupted Day in part), taking into account the restrictions of Rule 10b-18 under the Exchange Act agreed to hereunder, plus USD 0.02, multiplied by (ii) the Settlement Shares.
		
	Net Stock Settlement:	  	On any Settlement Date in respect of which Net Stock Settlement applies, if the Cash Settlement Amount is a (i) positive number, Dealer shall deliver through the Clearance System a number of Shares to Counterparty equal to the
Net Stock Settlement Shares, or (ii) negative number, Counterparty shall deliver through the Clearance System a number of Shares to Dealer equal to the Net Stock Settlement Shares; provided that if Dealer determines in its good faith
judgment that it would be required to deliver Net Stock Settlement Shares to Counterparty, Dealer may elect to deliver a portion of such Net Stock Settlement Shares on one or more dates prior to the applicable Settlement Date.

second Scheduled Trading Day preceding such Settlement Date (as such date may be changed by Dealer as described in the first proviso in clause (a) of the definition of Settlement Date above and provided that Dealer may truncate any
Unwind Period pending (and reduce the Settlement Shares for such Unwind Period to the portion thereof, if any, for which Dealer (or its affiliate) has determined an Unwind Purchase Price) at the time Dealer designates a Settlement Date pursuant to

Rule 10b-18 would be unavailable by virtue of the exclusions from the definition of “Rule 10b-18 purchase” under clauses (i) or (iv) thereof
(the period of unavailability, a “Rule 10b-18 Unavailability Period”). Dealer shall promptly notify Counterparty if it receives such advice from its counsel.

Effectiveness; Distribution Agreement; Interpretive Letter: 

Conditions to Effectiveness. Each Transaction shall be effective if and only if Shares are sold on or after the applicable Trade Date
and on or prior to the applicable Hedge Completion Date through the Distribution Agent pursuant to a “Forward Sale” under the Distribution Agreement. If the Distribution Agreement is terminated prior to any such sale of Shares thereunder,
the parties shall have no further obligations in connection with the relevant Transaction, other than in respect of breaches of representations or covenants on or prior to such date. 

Distribution Agreement Representations, Warranties and Covenants. On each Trade Date and on each date on which Dealer or its affiliates
deliver a prospectus in connection with a sale to hedge a Transaction, Counterparty repeats and reaffirms as of such date all of the representations and warranties contained in the Distribution Agreement. Counterparty hereby agrees to comply with
its covenants contained in the Distribution Agreement as if such covenants were made in favor of Dealer.

 Interpretive Letter. Counterparty agrees and acknowledges that each Transaction is
being entered into in accordance with the October 9, 2003 interpretive letter from the staff of the Securities and Exchange Commission to Goldman, Sachs & Co. (the “Interpretive Letter”) and agrees to take all actions,
and to omit to take any actions, reasonably requested by Dealer for each Transaction to comply with the Interpretive Letter. Without limiting the foregoing, Counterparty agrees that neither it nor any “affiliated purchaser” (as defined in
Regulation M (“Regulation M”) promulgated under the Exchange Act) will, directly or indirectly, bid for, purchase or attempt to induce any person to bid for or purchase, the Shares or securities that are convertible into, or
exchangeable or exercisable for, Shares during any “restricted period” as such term is defined in Regulation M. In addition, Counterparty represents that it is eligible to conduct a primary offering of Shares on Form S-3, the offering contemplated by the Distribution Agreement complies with Rule 415 under the Securities Act, and the Shares are “actively traded” as defined in Rule 101(c)(1) of
Regulation M. 
 Agreements and Acknowledgments Regarding Shares: 
  

	 	(i)	 Counterparty agrees and acknowledges that, in respect of any Shares delivered to Dealer (or its affiliates)
hereunder, such Shares shall be newly issued (unless mutually agreed otherwise by the parties) and upon such delivery, duly and validly authorized, issued and outstanding, fully paid and nonassessable, free of any lien, charge, claim or other
encumbrance and not subject to any preemptive or similar rights and shall, upon such issuance, be accepted for listing or quotation on the Exchange. 


  

	 	(ii)	 Counterparty agrees and acknowledges that Dealer (or its affiliates) will hedge its exposure to each
Transaction by selling Shares borrowed from third-party securities lenders or other Shares pursuant to a registration statement, and that, pursuant to the terms of the Interpretive Letter, the Shares (up to the Initial Number of Shares) delivered,
pledged or loaned by Counterparty to Dealer (or its affiliates) in connection with each Transaction may be used by Dealer (or its affiliates) to return to securities lenders without further registration under the Securities Act. Accordingly,
Counterparty agrees that the Shares that it delivers, pledges or loans to Dealer (or its affiliates) on or prior to the final 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. 


  

	 	(iii)	 Counterparty has reserved and will keep available at all times, free from preemptive or similar rights and free
from any lien, charge, claim or other encumbrance, authorized but unissued Shares at least equal to the Number of Shares for all Transactions, solely for the purpose of settlement under the Transactions. 



  
 15 














	 	(iv)	 Unless the provisions set forth below under “Private Placement and Registration Procedures” are
applicable, Dealer agrees to use or cause its affiliates to use any Shares delivered by Counterparty hereunder on any Settlement Date to return to securities lenders to close out open securities loans with respect to the Shares.



  

	 	(v)	 In connection with bids and purchases of Shares in connection with any Cash Settlement or Net Stock Settlement
of a Transaction, Dealer shall use its good faith efforts to comply, or cause compliance, with the provisions of Rule 10b-18 under the Exchange Act, taking into account any purchases under other Forward
Contracts (as defined herein), as if such provisions were applicable to such purchases. “Forward Contract” shall mean any Transaction relating to Shares sold through the Distribution Agent pursuant to a “Forward Sale”
under the Distribution Agreement and any similar transaction relating to Shares sold by an affiliate of Dealer pursuant to an underwriting agreement (or equivalent agreement). 



Securities Laws Representations and Agreements: 
  

	 	(i)	 Counterparty represents to Dealer on each Trade Date and on any date that Counterparty notifies Dealer that
Cash Settlement, Net Stock Settlement or Alternative Settlement under “Accounting Standards Codification 815-40; Alternative Settlement” below applies to a Transaction, that (a) each of its
filings under the Securities Act, the Exchange Act or other applicable securities laws that are required to be filed have been filed and that, as of the respective dates thereof and as of the date of this representation, there is no misstatement of
material fact contained therein or omission of a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading and (b) it has not and
will not directly or indirectly violate any applicable law (including, without limitation, the Securities Act and the Exchange Act) in connection with a Transaction. In addition to any other requirement set forth herein, Counterparty agrees not to
designate any Settlement Date or elect Alternative Settlement under “Accounting Standards Codification 815-40; Alternative Settlement” below if settlement in respect of such date would result in a
violation of any applicable federal or state law or regulation, including the U.S. federal securities laws. 


  

	 	(ii)	 It is the intent of Dealer and Counterparty that following any election of Cash Settlement or Net Stock
Settlement by Counterparty for a Transaction, the purchase of Shares by Dealer (or its affiliates) during the related Unwind Period complies with the requirements of Rule 10b5-l(c)(l)(i)(B) of the Exchange Act
and that this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, shall be interpreted to comply with the requirements of Rule 10b5-l(c). 



  
 16 













 Counterparty acknowledges that (a) during any Unwind Period, Counterparty shall not
have, and shall not attempt to exercise, any influence over how, when or whether to effect purchases of Shares by Dealer (or its agent or affiliate) in connection with this Master Confirmation, each Instruction or Terms Agreement and the Pricing
Supplement, if any, and (b) Counterparty is entering into the Agreement and this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, 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. 

Counterparty hereby agrees with Dealer that during any Unwind Period Counterparty shall not communicate, directly or indirectly, any Material Non-Public Information (as defined herein) to any Equity Derivatives Group Personnel (as defined below). For purposes of each Transaction, “Material Non-Public
Information” means information relating to Counterparty or the Shares that (x) has not been widely disseminated by wire service, in one or more newspapers of general circulation, by communication from Counterparty to its shareholders
or in a press release, or contained in a public filing made by Counterparty with the Securities and Exchange Commission and (y) 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 orders, significant merger or acquisition proposals or agreements, significant new products or discoveries, extraordinary borrowing, major
litigation, liquidity problems, extraordinary management developments, purchase or sale of substantial assets, or other similar information. For purposes of each Transaction, “Equity Derivatives Group Personnel” means any employee
of Dealer or its affiliates who effects purchases or sales of Shares in connection with this Master Confirmation. 
  

	 	(iii)	 Counterparty shall, at least one day prior to the first day of any Unwind Period, notify Dealer of the total
number of Shares purchased in Rule 10b-18 purchases of blocks pursuant to the once-a-week block exception contained in Rule 10b-18(b)(4) by or for Counterparty or any of its affiliated purchasers during each of the four calendar weeks preceding the first day of the Unwind Period and during the calendar week in which the first day of the
Unwind Period occurs (“Rule 10b-18 purchase”, “blocks” and “affiliated purchaser” each being used as defined in Rule 10b-18).



  

	 	(iv)	 During any Unwind Period, Counterparty shall (a) notify Dealer prior to the opening of trading in the
Shares on any day on which Counterparty makes, or expects to be made, any public announcement (as defined in Rule 165(f) under the Securities Act) of any merger, acquisition, or similar transaction involving




  
 17 














	 	
a recapitalization relating to Counterparty (other than any such transaction in which the consideration consists solely of cash and there is no valuation period), (b) promptly notify Dealer
following any such announcement that such announcement has been made, and (c) promptly deliver to Dealer following the making of any such announcement information indicating (1) Counterparty’s average daily Rule 10b-18 purchases (as defined in Rule 10b-18) during the three full calendar months preceding the date of the announcement of such transaction and
(2) Counterparty’s block purchases (as defined in Rule 10b-18) effected pursuant to paragraph (b)(4) of Rule 10b-18 during the three full calendar
months preceding the date of the announcement of such transaction. In addition, Counterparty shall promptly notify Dealer of the earlier to occur of the completion of such transaction and the completion of the vote by target shareholders.


  

	 	(v)	 Neither Counterparty nor any of its affiliates shall take or refrain from taking any action (including, without
limitation, any direct purchases by Counterparty or any of its affiliates, or any purchases by a party to a derivative transaction with Counterparty or any of its affiliates), either under this Master Confirmation, each Instruction or Terms
Agreement and the Pricing Supplement, if any, under an agreement with another party or otherwise, that might cause any purchases of Shares by Dealer or any of its affiliates in connection with any Cash Settlement or Net Stock Settlement of a
Transaction not to meet the requirements of the safe harbor provided by Rule 10b-18 determined as if all such foregoing purchases were made by Counterparty. Without limiting the foregoing, Counterparty may not
elect Cash Settlement or Net Stock Settlement during a Rule 10b-18 Unavailability Period. 


  

	 	(vi)	 Counterparty will not engage in any “distribution” (as defined in Regulation M) that would cause a
“restricted period” (as defined in Regulation M) to occur during any Unwind Period. 


 Miscellaneous: 

Acceleration Events. 
  

	 	(i)	 Stock Borrow Event. If in Dealer’s reasonable judgment, (a) Dealer (or its affiliate) is not
able to hedge Dealer’s exposure under a Transaction because insufficient Shares are made available for borrowing by securities lenders or (b) Dealer (or its affiliate) would incur a cost to borrow (or to maintain a borrow of) sufficient
Shares to hedge Dealer’s exposure under a Transaction that is equal to or greater than 300 basis points per annum per any Share (each of (a) and (b), a “Stock Borrow Event”), then Dealer shall be entitled to designate any
Scheduled Trading Day prior to the date the applicable Number of Shares is first reduced to zero to be a Settlement Date for such Transaction, by providing Counterparty at least two Scheduled Trading Days’ notice prior to the relevant
Settlement Date, and to designate the number of Settlement Shares for the relevant Settlement Date, which shall not exceed the number of Shares as to which the relevant Stock Borrow Event relates. 



  
 18 














	 	(ii)	 Dividends. If on any day after a Trade Date, Counterparty declares a distribution, issue or dividend to
existing holders of the Shares of (a) any cash dividends: (x) with an ex-dividend date occurring prior to the ex-dividend date for such calendar quarter
provided for in the applicable Instruction for such Transaction, or (y) the amount or value of which per Share (as determined by the Calculation Agent), when aggregated with the amount or value (as determined by the Calculation Agent) of any
and all previous dividends with ex-dividend dates occurring in the same calendar quarter, exceeds the amount for such quarter provided in the latest Instruction for such Transaction or (b) share capital
or other securities of another issuer acquired or owned (directly or indirectly) by Counterparty as a result of a spin-off or similar transaction or (c) any other type of securities (other than Shares),
rights or warrants or other assets, in any case for payment (cash or other consideration) at less than the prevailing market price, as determined by Dealer, then for each affected Transaction Dealer shall be entitled to designate any Scheduled
Trading Day prior to the date the applicable Number of Shares is first reduced to zero to be a Settlement Date for such Transaction, by providing Counterparty at least three Scheduled Trading Days’ notice prior to the relevant Settlement Date,
and to designate the number of Settlement Shares for the relevant Settlement Date. For the avoidance of doubt, any amount calculated pursuant to this Acceleration Event shall not be adjusted by the value associated with such distribution, issue or
dividend. Counterparty agrees that it will publicly announce any such distribution, issue or dividend at least five Scheduled Trading Days before the record date therefor. 



 

	 	(iii)	 Stock Price Event. If at any time after a Trade Date the traded price per Share on the Exchange is less
than or equal to 35% of the applicable Initial Forward Price, then for each affected Transaction Dealer shall be entitled at any time thereafter to designate one or more Scheduled Trading Days prior to the date the applicable Number of Shares is
first reduced to zero to be a Settlement Date for such Transaction, by providing Counterparty at least ten Scheduled Trading Days’ notice prior to the relevant Settlement Date, and to designate the number of Settlement Shares for the relevant
Settlement Date. 


  

	 	(iv)	 Announcement of Merger Event. If on any day after a Trade Date, Counterparty announces any event that,
if consummated, would constitute a Merger Event, then Counterparty shall notify Dealer of such occurrence within one Scheduled Trading Day after such occurrence and for each affected Transaction Dealer shall be entitled to designate any Scheduled
Trading Day prior to the date the applicable Number of Shares is first reduced to zero to be a Settlement Date for such Transaction, by providing Counterparty at least one Scheduled Trading Day’s notice prior to the relevant Settlement Date,
and to designate the number of Settlement Shares for the relevant Settlement Date. 



  
 19 














	 	(v)	 ISDA Termination. In lieu of (a) designating an Early Termination Date as the result of an Event of
Default or Termination Event, (b) terminating a Transaction and determining a Cancellation Amount as the result of an Additional Disruption Event, or (c) terminating a Transaction and determining an amount payable in connection with an
Extraordinary Event to which Cancellation and Payment would otherwise be applicable, Dealer shall be entitled to designate for each affected Transaction any Scheduled Trading Day prior to the date the applicable Number of Shares is first reduced to
zero to be a Settlement Date for such Transaction with respect to the applicable Number of Shares as the Settlement Shares. 


  

	 	(vi)	 Termination Settlement. Notwithstanding anything to the contrary herein, in the Agreement or in the
Equity Definitions, if a Settlement Date is designated by Dealer as the result of one of the foregoing sub-paragraphs (i) through (v), Physical Settlement shall apply to the relevant Settlement Shares.



 Private Placement and Registration Procedures. If Counterparty notifies Dealer that it is unable to comply with
the provisions of sub-paragraph (ii) of “Agreements and Acknowledgments Regarding Shares” above because of a change in law or a change in the policy of the Securities and Exchange Commission or
its staff, or Dealer notifies Counterparty that in its reasonable opinion any Shares to be delivered to Dealer (or its affiliate) by Counterparty may not be freely returned by Dealer (or its affiliate) to securities lenders as described under such sub-paragraph (ii), or otherwise constitute “restricted securities” as defined in Rule 144 under the Securities Act (the date such notification is effective being the “Determination
Date”), then Counterparty may elect to effect the delivery of any such Shares (the “Restricted Shares”) pursuant to either clause (i) or (ii) below, unless waived by Dealer, on the later of (A)(1) if Private Placement
Settlement is applicable, the tenth Scheduled Trading Day following the Determination Date or (2) if Registration Settlement is applicable, the thirtieth calendar day following the Determination Date (or if such day is not a Clearance System
Business Day, the next Clearance System Business Day), (B) the date such delivery would otherwise be due pursuant to the terms of this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, and (C) the
Clearance System Business Day following notice by Dealer to Counterparty of the number of Shares to be delivered pursuant to these “Private Placement and Registration Procedures”; provided that if Counterparty does not so elect
within three Scheduled Trading Days of the Determination Date, Counterparty shall be deemed to have elected clause (i) below. 
  

	 	(i)	 If Counterparty is obligated to settle any Transaction with Restricted Shares (a “Private Placement
Settlement”), then delivery of Restricted Shares by Counterparty shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Dealer; provided that Counterparty may not
elect a Private Placement Settlement if, on the date of its election, it has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(a)(2) of the Securities Act for the sale by
Counterparty to Dealer (or any affiliate designated by 



  
 20 














	 	
Dealer) 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 Dealer (or any such
affiliate of Dealer). The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer and its affiliates, due
diligence rights (for Dealer, any affiliate designated by Dealer or any buyer of the Restricted Shares designated by Dealer or its affiliate), opinions and certificates, and such other documentation as is customary for private placement agreements,
all reasonably acceptable to Dealer. In the case of a Private Placement Settlement, Dealer shall, in its good faith discretion, adjust the amount of Restricted Shares to be delivered to Dealer (or its affiliate) hereunder in a commercially
reasonable manner to reflect the fact that (A) such Restricted Shares may not be freely returned to securities lenders by Dealer (or its affiliate) and may only be saleable by Dealer (or its affiliates) at a discount to reflect the lack of
liquidity in Restricted Shares and (B) Dealer (or its affiliate) will incur carrying costs and other costs in connection with the unwind of Dealer’s hedge as it relates to such Private Placement Settlement; provided that for any
Transaction in no event will Counterparty be required to deliver to Dealer (or its affiliate) a number of Restricted Shares in excess of (i) the applicable Initial Number of Shares multiplied by two, minus (ii) the aggregate
number of Shares delivered by Counterparty to Dealer (or its affiliate) under such Transaction prior to the date of such delivery (the “Maximum Delivery Amount”). If Dealer adjusts the amount of Restricted Shares, it shall provide
Counterparty with a statement indicating in reasonable detail how such share adjustment was determined. 

 If Counterparty
delivers any Restricted Shares in respect of a Transaction, Counterparty agrees that (A) such Shares may be transferred by and among Dealer and its affiliates and (B) after the “holding period” specified in Rule 144(d) under
the Securities Act has elapsed, Counterparty 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 Dealer (or such affiliate of Dealer) to
Counterparty or such transfer agent of any seller’s and broker’s representation letters customarily delivered by Dealer 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 Dealer (or such
affiliate of Dealer). 
  

	 	(ii)	 If Counterparty elects to settle a Transaction pursuant to this clause (ii) (a “Registration
Settlement”), then Counterparty shall promptly (but in any event no later than the Scheduled Trading Day immediately prior to the date delivery of the Shares is due pursuant to the terms of these “Private Placement and Registration
Procedures”) file and use its reasonable efforts to make effective under the Securities Act a registration statement or supplement or amend an outstanding registration statement in form and substance reasonably




  
 21 














	 	
satisfactory to Dealer, to cover the resale of Restricted Shares (the “Registered Shares”) in accordance with customary resale registration procedures, including covenants,
conditions, representations, underwriting discounts, commissions, indemnities, due diligence rights, opinions and certificates, and such other documentation as is customary for equity resale underwriting agreements, all reasonably acceptable to
Dealer. If Dealer, in its reasonable discretion, is not satisfied with such procedures and documentation or if a Settlement Date is designated by Dealer pursuant to the “Acceleration Events” provisions above, Private Placement Settlement
shall apply and Counterparty shall effect delivery of Restricted Shares by the tenth Scheduled Trading Day following notification from Dealer. In the case of a Registration Settlement, Dealer shall, in its good faith discretion, adjust the amount of
Registered Shares to be delivered to Dealer (or its affiliate) under the relevant Transaction in a commercially reasonable manner to reflect the fact that Dealer (or its affiliate) will incur carrying costs and other costs in connection with the
unwind of Dealer’s hedge as it relates to such Registered Settlement; provided that for any Transaction in no event will Counterparty be required to deliver to Dealer (or its affiliate) a number of Registered Shares in excess of the
Maximum Delivery Amount for such Transaction. If Dealer adjusts the amount of Registered Shares, it shall provide Counterparty with a statement indicating in reasonable detail how such share adjustment was determined. 


Indemnity. Counterparty agrees to indemnify Dealer and its affiliates and their respective directors, officers, employees, agents and
controlling persons (Dealer 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, the execution or delivery of this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, the performance by the parties hereto of their respective
obligations under any Transaction, any breach of any covenant or representation made by Counterparty in this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, or the Agreement or the consummation of the
transactions contemplated hereby 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, except to the extent resulting from Dealer’s gross negligence or willful misconduct. 

Waiver of Trial by Jury. EACH OF COUNTERPARTY AND DEALER HEREBY IRREVOCABLY WAIVES (ON ITS OWN BEHALF AND, TO THE EXTENT PERMITTED BY
APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS) ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY TRANSACTION OR THE ACTIONS OF DEALER OR ITS
AFFILIATES IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF. 

  
 22 













 Governing Law/Jurisdiction. This Master Confirmation, each Instruction or Terms
Agreement and the Pricing Supplement, if any, shall be governed by the laws of the State of New York without reference to the conflict of laws provisions thereof. The parties hereto irrevocably submit to the exclusive jurisdiction of the courts of
the State of New York and the United States Court for the Southern District of New York in connection with all matters relating hereto and waive any objection to the laying of venue in, and any claim of inconvenient forum with respect to, these
courts. 
 Designation by Dealer. Notwithstanding any other provision in this Master Confirmation, each Instruction or Terms Agreement
and the Pricing Supplement, if any, to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or
deliver such Shares or other securities and otherwise to perform Dealer obligations in respect of any Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty only to the extent of
any such performance. 
 Accounting Standards Codification 815-40; Alternative Settlement. The
parties hereby agree that all documentation with respect to a Transaction is intended to qualify such Transaction as an equity instrument for purposes of Accounting Standards Codification 815-40. If, subject
to “Netting and Set-off” below, Counterparty owes Dealer any amount in connection with a Transaction pursuant to Section 12.7 or 12.9 of the Equity Definitions (except in the case of an
Extraordinary Event in which the consideration or proceeds to be paid to holders of Shares as a result of such event consists solely of cash) or pursuant to Section 6(d)(ii) of the Agreement (except in the case of an Event of Default in which
Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party, other than (x) an Event of Default of the type described in Section 5(a)(iii), (v), (vi) or (vii) of the Agreement or (y) a
Termination Event of the type described in Section 5(b)(i), (ii), (iii), (iv), or (v) of the Agreement that in the case of either (x) or (y) resulted from an event or events outside Counterparty’s control) (a “Payment
Obligation”), Counterparty shall have the right, in its sole discretion, to satisfy any such Payment Obligation by delivery of Termination Delivery Units (as defined below) by giving irrevocable telephonic notice to Dealer, confirmed in
writing within one Scheduled Trading Day, between the hours of 9:00 a.m. and 4:00 p.m. New York time on the Closing Date, Early Termination Date or other date of termination or cancellation, as applicable (“Notice of Termination
Delivery”). Upon Notice of Termination Delivery, Counterparty shall deliver to Dealer a number of Termination Delivery Units having a cash value equal to the amount of such Payment Obligation (such number of Termination Delivery Units to be
delivered to be determined by the Calculation Agent acting in a commercially reasonable manner, taking into account whether the Termination Delivery Units so delivered are freely tradable). Settlement relating to any delivery of Termination Delivery
Units pursuant to this provision shall occur within two Scheduled Trading Days. “Termination Delivery Unit” means (A) in the case of a Termination Event, an Event of Default or an Extraordinary Event (other than an Insolvency,
Nationalization, Merger Event or Tender Offer), one Share or (B) in the case of an Insolvency, Nationalization, Merger Event or Tender Offer, a unit consisting of the number or 

  
 23 













 
amount of each type of property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in
such Insolvency, Nationalization, Merger Event or Tender Offer; provided that if such Insolvency, Nationalization, Merger Event or Tender Offer involves a choice of consideration to be received by holders, such holder shall be deemed to have
elected to receive the maximum possible amount of cash. 
 Disclosure. Effective from the date of commencement of discussions
concerning a Transaction, each of Dealer and Counterparty and each of their employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of such Transaction and
all materials of any kind (including opinions or other tax analyses) relating to such tax treatment and tax structure. 
 Right to
Extend. Dealer may postpone any Settlement Date or any other date of valuation or delivery, with respect to some or all of the relevant Settlement Shares, if Dealer determines, in its discretion, that such extension is reasonably necessary or
appropriate to enable Dealer (or its affiliate) to effect purchases of Shares in connection with Dealer’s hedging activity hereunder or under any other Forward Contract in a manner that would, if Dealer (or its affiliate) were Counterparty or
an affiliated purchaser of Counterparty, be in compliance with applicable legal and regulatory requirements, as determined by Dealer based upon the advice of outside counsel of national standing. 

Counterparty Share Repurchases. Counterparty agrees not to repurchase any Shares if, immediately following such purchase, the Number of
Shares for all Transactions under this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, and all other Forward Contracts would be equal to or greater than 8.0% of the number of then-outstanding Shares or
such lower number of Shares as Dealer notifies Counterparty would, in the reasonable judgment of outside counsel of national standing for Dealer, present legal or regulatory issues for Dealer or its affiliates. 

Limit on Beneficial Ownership. Notwithstanding any other provisions hereof, neither Dealer nor its affiliates shall be entitled to
receive Shares hereunder (whether in connection with the purchase of Shares on any Settlement Date or otherwise) to the extent (but only to the extent) that such receipt would result in Dealer and its affiliates or any “group” of which
Dealer (or its affiliates) is a part (i) directly or indirectly beneficially owning (as such term is defined for purposes of Section 13(d) of the Exchange Act or, if it would result in a higher percentage of beneficial ownership, the
equivalent calculation for purposes of determining a ten percent beneficial owner under Section 16 of the Exchange Act) at any time in excess of 4.9% of the outstanding Shares or (ii) having direct or indirect ownership or control (for
purposes of the Bank Holding Company Act of 1956, as amended) at any time in excess of 4.9% of the outstanding Shares. Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that such delivery would
result in Dealer and its affiliates or such a group directly or indirectly so beneficially owning or so owning or 

  
 24 













 
controlling in excess of 4.9% of the outstanding Shares. If any delivery owed to Dealer (or its affiliates) hereunder is not made, in whole or in part, as a result of this provision,
Counterparty’s obligation to make such delivery shall not be extinguished and Counterparty shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Dealer gives notice to
Counterparty that such delivery would not result in Dealer and its affiliates or such a group directly or indirectly so beneficially owning or so owning or controlling in excess of 4.9% of the outstanding Shares. 

Commodity Exchange Act. Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” as
defined in the U.S. Commodity Exchange Act, as amended (the “CEA”), and the Agreement and each Transaction are subject to individual negotiation by the parties and have not been executed or traded on a “trading facility”
as defined in the CEA. 
 Securities Act. Each of Dealer and Counterparty agrees and represents that it is a “qualified
institutional buyer” as defined in Rule 144A under the Securities Act, or an “accredited investor” as defined under the Securities Act. 

ERISA. Each of Dealer and Counterparty agrees and represents that the assets used in each Transaction (a) are not assets of any
“plan” (as such term is defined in Section 4975 of the Code) subject to Section 4975 of the Code or any “employee benefit plan” (as such term is defined in Section 3(3) of the U.S. Employee Retirement Income
Security Act of 1974, as amended (“ERISA”)) subject to Title I of ERISA, and (b) do not constitute “plan assets” (as such term is defined in Section 3(42) of ERISA). 

Bankruptcy Status. Dealer acknowledges and agrees that this Master Confirmation, each Instruction or Terms Agreement and the Pricing
Supplement, if any, is not intended to convey to Dealer rights with respect to the transactions contemplated hereby that are senior to the claims of Counterparty’s common stockholders in any U.S. bankruptcy proceedings of Counterparty;
provided that nothing herein shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to this Master Confirmation, each Instruction or Terms
Agreement and the Pricing Supplement, if any, and the Agreement; and provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transaction other than the Transactions. 

No Collateral. The parties acknowledge that none of the Transactions are secured by any collateral that would otherwise secure the
obligations of Counterparty herein under or pursuant to the Agreement. Without limiting the generality of the foregoing, none of the Transactions will be considered to create obligations covered by any collateral credit support annex to the
Agreement and will be disregarded for the purposes of calculating any exposures pursuant to any such annex. 

  
 25 













 Netting and Set-off. Dealer agrees not to set-off or net amounts due from Counterparty with respect to any Transaction against amounts due from Dealer to Counterparty under obligations other than Equity Contracts. Section 2(c) of the Agreement as it
applies to payments due with respect to any Transaction shall remain in effect and is not subject to the first sentence of this provision. The parties agree that Section 6(f) of the Agreement is amended and restated to read as follows: 

“(f) Upon the occurrence of an Event of Default or Termination Event with respect to Counterparty as the Defaulting Party or the Affected
Party (“X”), Dealer (“Y”) will have the right (but not be obliged) without prior notice to X or any other person to set-off or apply any obligation of X under an Equity Contract owed to Y
(or any Affiliate of Y) (whether or not matured or contingent and whether or not arising under this Agreement, and regardless of the currency, place of payment or booking office of the obligation) against any obligation of Y (or any Affiliate of Y)
under an Equity Contract owed to X (whether or not matured or contingent and whether or not arising under this Agreement, and regardless of the currency, place of payment or booking office of the obligation). Y will give notice to the other party of
any set-off effected under this Section 6(f). 
 “Equity Contract” shall mean, for
purposes of this Section 6(f), any Transaction relating to Shares sold through the Distribution Agent pursuant to a “Forward Sale” under the Distribution Agreement. 

If any obligation is unascertained, Y may in good faith estimate that obligation and set-off in respect
of the estimate, subject to the relevant party accounting to the other when the obligation is ascertained. 
 Nothing in this
Section 6(f) shall be effective to create a charge or other security interest. This Section 6(f) shall be without prejudice and in addition to any right of set-off, combination of accounts, lien or
other right to which any party is at any time otherwise entitled (whether by operation of law, contract or otherwise).” 
 Wall
Street Transparency and Accountability Act of 2010. The parties hereby agree that none of (a) Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), (b) any similar legal certainty
provision in any legislation enacted, or rule or regulation promulgated, on or after any Trade Date, (c) the enactment of WSTAA or any regulation under the WSTAA, (d) any requirement under WSTAA nor (e) an amendment made by WSTAA,
shall limit or otherwise impair either party’s rights to terminate, renegotiate, modify, amend or supplement this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, or the Agreement, as applicable,
arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Master Confirmation, each Instruction or Terms Agreement and the Pricing Supplement, if any, the Equity Definitions
incorporated herein, or the Agreement (including, but not limited to, rights arising from Change in Law, Increased Cost of Stock Borrow or Illegality (as defined in the Agreement)). 

  
 26 













 Tax Representations. 

 

	 	(i)	 For the purpose of Section 3(e) of the Agreement, each party makes the following representation:



  

	 	    	 It is not required by any applicable law, as modified by the practice of any relevant governmental revenue
authority, of any Relevant Jurisdiction to make any deduction or withholding for or on account of any Tax from any payment (other than interest under Section 9(h) of the Agreement or any other payments of interest or penalty charges for late
payment) to be made by it to the other party under the Agreement. 


 In making this representation, a party 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;
