 Ladies and Gentlemen: 
 Silicon Laboratories
Inc., a Delaware corporation (the “Company”), proposes, subject to the terms and conditions set forth in this agreement (this “Agreement”), to issue and sell to the purchasers named in Schedule I hereto (the “Initial
Purchasers”), for whom you are acting as representatives (the “Representatives”), an aggregate of $350,000,000 principal amount of the 1.375% Convertible Senior Notes due 2022 (the “Firm Securities”) and, at the election of
the Initial Purchasers, up to an aggregate of $50,000,000 additional aggregate principal amount of such 1.375% Convertible Senior Notes due 2022 (the “Optional Securities”). The Firm Securities and any Optional Securities that the Initial

“Underlying Common Stock” and such common stock, the “Common Stock”), or a combination of cash and Common Stock, at the Company’s election, as set forth in the Pricing Disclosure Package and the Offering Circular (each as
defined below). 
  

	1.	Representations and Warranties. The Company represents and warrants to, and agrees with, each of the Initial Purchasers that: 


 

	 	(a)	 Incorporation of Documents by Reference. A preliminary offering circular, dated February 27, 2017
(the “Preliminary Offering Circular”), and an offering circular, dated February 28, 2017 (the “Offering Circular”), have been prepared in connection with the offering of the Securities and shares of the
Underlying Common Stock, if any, issuable upon conversion thereof. The Preliminary Offering Circular, as amended and supplemented immediately prior to the Applicable Time (as defined in Section 1(b)), is hereinafter referred to as the
“Pricing Circular”. Any reference to the Preliminary Offering Circular, the Pricing Circular or the  










	 	
Offering Circular shall be deemed to refer to and include all documents filed with the United States Securities and Exchange Commission (the “Commission”) pursuant to Section 13(a),
13(c) or 15(d) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or prior to the date of such circular and incorporated by reference therein and any reference to the Preliminary Offering Circular or
the Offering Circular, as the case may be, as amended or supplemented, as of any specified date, shall be deemed to include (i) any documents filed with the Commission pursuant to Section 13(a), 13(c) or 15(d) of the Exchange Act after the date
of the Preliminary Offering Circular or the Offering Circular, as the case may be, and prior to such specified date and (ii) any Additional Issuer Information (as defined in Section 5(f)) furnished by the Company prior to the completion of the
distribution of the Securities; and all documents filed under the Exchange Act and so deemed to be included in the Preliminary Offering Circular, the Pricing Circular or the Offering Circular, as the case may be, or any amendment or supplement
thereto are hereinafter called the “Exchange Act Reports” (provided that where only sections of such documents are specifically incorporated by reference, only such sections shall be considered to be part of the “Exchange Act
Reports”). The Exchange Act Reports, when they were or are filed with the Commission, conformed or will conform in all material respects to the applicable requirements of the Exchange Act and the applicable rules and regulations of the
Commission thereunder; and no such documents were filed with the Commission since the Commission’s close of business on the business day immediately prior to the date of this Agreement and prior to the execution of this Agreement, except as set
forth on Schedule II(a) hereof. The Preliminary Offering Circular or the Offering Circular and any amendments or supplements thereto and the Exchange Act Reports did not and will not, as of their respective dates, contain an untrue statement
of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that this representation and
warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by an Initial Purchaser through the Representatives expressly for use therein, which information is
limited to the information set forth in Section 9(f);

Disclosure Package”) as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they
were made, not misleading; and each Company Supplemental Disclosure Document (as defined in Section 6(a)(i)) listed on Schedule II(b) hereto and each Permitted General Solicitation Material (as defined in Section 6(a)(i)) listed on Schedule
II(d) hereto) does not conflict with the information contained in the Pricing Circular or the Offering Circular and each such Company Supplemental Disclosure Document and Permitted General Solicitation Material, as supplemented by and taken
together with the Pricing Disclosure Package as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading; provided, however, that this representation and warranty shall not apply to statements or omissions made in a Company Supplemental Disclosure Document or

	 	(j)	Absence of Manipulation. Prior to the date hereof, neither the Company nor any of its affiliates has taken any action which is designed to or which has constituted or which might have been expected to cause or
result in stabilization or manipulation of the price of any security of the Company in connection with the offering of the Securities; 

  

	 	(k)	 Absence of Violations, Defaults and Conflicts. The issue and sale of the Securities and the issuance, if
any, of the Underlying Common Stock upon conversion of the Securities, the compliance by the Company with all of the provisions of the Securities, the Indenture and this Agreement, the consummation of the transactions herein and therein contemplated
and the application of the proceeds from the sale of the Securities as described under “Use of Proceeds” in the Pricing Disclosure Package and the Offering Circular will not conflict with or result in a breach or violation of any of the
terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the




  
 4

	4.	Payment; Time of Delivery. 

  

	 	(a)	The Securities to be purchased by each Purchaser hereunder will be represented by one or more definitive global Securities in book-entry form which will be deposited by or on behalf of the Company with The Depository
Trust Company (“DTC”) or its designated custodian. The Company will deliver the Securities to the Representatives, for the account of each Purchaser, against payment by or on behalf of such Initial Purchaser of the purchase price therefor
by wire transfer of Federal (same day) funds, by causing DTC to credit the Securities to the account of Wells Fargo Securities, LLC at DTC. The Company will cause the certificates representing the Securities to be made available to the
Representatives for checking at least twenty-four hours prior to each Time of Delivery (as defined below) at the office of Davis Polk & Wardwell LLP, 450 Lexington Avenue, New York, New York 10017 (the “Closing
Location”). The time and date of such delivery and payment shall be, with respect to the Firm Securities, 9:30 a.m., New York City time, on March 6, 2017 or such other time and date as the Representatives and the Company may agree
upon in writing, and, with respect to the Optional Securities, 9:30 a.m., New York City time, on the date specified by you in the written notice given by the Representatives of the Initial Purchasers’ election to purchase such Optional
Securities, or such other time and date as the Representatives and the Company may agree upon in writing. Such time and date for delivery of the Firm Securities is herein called the “First Time of Delivery”, and each of the First Time of
Delivery and any subsequent time and date for delivery of the Optional Securities, if not the First Time of Delivery, is herein called a “Time of Delivery”. 


 

	 	(b)	The documents to be delivered at each Time of Delivery by or on behalf of the parties hereto pursuant to Section 8 hereof, including the cross-receipt for the Securities and any additional documents requested by
the Initial Purchasers pursuant to Section 8(k) hereof, will be delivered at such time and date at the Closing Location, and the Securities will be delivered at the office of DTC (or its designated custodian), all at such Time of Delivery. A meeting
will be held at the Closing Location at 4:00 p.m., New York City time, on the New York Business Day next preceding such Time of Delivery, at which meeting the final drafts of the documents to be delivered pursuant to the preceding sentence will be
available for review by the parties hereto. For the purposes of this Section 4, “New York Business Day” shall mean each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in New York are
generally authorized or obligated by law or executive order to close. 

  

	5.	Covenants of the Company. The Company agrees with each of the Initial Purchasers: 

  

	 	(a)	To prepare the Offering Circular in a form approved by you; to make no amendment or any supplement to the Offering Circular which shall be disapproved by you promptly after reasonable notice thereof; and to furnish you
with copies thereof; 

  

	 	(b)	Promptly from time to time to take such action as you may reasonably request to qualify the Securities and the Underlying Common Stock for offering and sale under the securities laws of such jurisdictions as you may
request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Securities, provided that in connection therewith the
Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction; 

  

	 	(c)	 To furnish the Initial Purchasers with written and electronic copies of the Offering Circular and any

reasonably request, and if, at any time prior to the earlier of (i) the termination of the distribution of the Securities and (ii) the expiration of nine months after the date of the
Offering Circular, any event shall have occurred as a result of which the Offering Circular as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were made when such Offering Circular is delivered, not misleading, or, if for any other reason it shall be necessary or desirable during such same period to amend or supplement
the Offering Circular, to notify you and upon your request to prepare and furnish without charge to each Purchaser and to any dealer in securities as many written and electronic copies as you may from time to time reasonably request of an
amended Offering Circular or a supplement to the Offering Circular which will correct such statement or omission or effect such compliance; 

  

	 	(d)	During the period beginning from the date hereof and continuing until the date that is 90 days after the First Time of Delivery, not to (i) offer, issue, sell, contract to sell, pledge, grant any option to
purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, or file with the Commission a registration statement under the Act relating to any securities of the Company that are substantially similar to the Securities

any offer, sale, pledge, disposition or filing or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or any such other securities, whether any such
transaction is to be settled by delivery of Common Stock or such other securities, in cash or otherwise (other than (x) pursuant to employee stock option plans existing on, or upon the conversion or exchange of convertible or exchangeable
securities outstanding as of, the date of this Agreement and (y) issuances of the Securities pursuant to this Agreement and any Common Stock issued upon conversion of the Securities), without your prior written consent; 


 

	 	(e)	Not to be or become, at any time prior to the expiration of two years after the First Time of Delivery, an open-end investment company, unit investment trust, closed-end investment company or face-amount certificate company that is or is required to be registered under Section 8 of the Investment Company Act; 


 

	 	(f)	At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, for the benefit of holders from time to time of Securities, to furnish at its expense, upon request, to holders of Securities
and prospective purchasers of Securities information (the “Additional Issuer Information”) satisfying the requirements of subsection (d)(4)(i) of Rule 144A under the Act; 


 

	 	(g)	Except for such documents that are publicly available on EDGAR, to furnish to the holders of the Securities as soon as practicable after the end of each fiscal year an annual report (including a balance sheet and

year (beginning with the fiscal quarter ending after the date of the Offering Circular), to make available to its stockholders consolidated summary financial information of the Company and its subsidiaries for such quarter in reasonable detail;



  
 11 









	 	(h)	During the period of one year after the last Time of Delivery, the Company will not, and will not permit any of its “affiliates” (as defined in Rule 144 under the Act) to, resell any of the Securities
which constitute “restricted securities” under Rule 144 that have been reacquired by any of them (other than pursuant to a registration statement that has been declared effective under the Act); 


 

	 	(i)	To use the net proceeds received by the Company from the sale of the Securities pursuant to this Agreement in the manner specified in the Pricing Circular under the caption “Use of Proceeds”;


  

	 	(j)	To reserve and keep available at all times, free of preemptive rights, a number of shares of Common Stock equal to the Maximum Number of Underlying Securities for the purpose of enabling the Company to satisfy any
obligations to issue shares of its Common Stock upon conversion of the Securities; and 

  

	 	(k)	To use its commercially reasonable efforts to list, subject to notice of issuance, a number of shares of Common Stock equal to the Maximum Number of Underlying Securities on the NASDAQ Global Select Market

	6.	Additional Covenants. 

  

	 	(a)	(i) The Company represents and agrees that, without the prior consent of the Representatives, it and its affiliates and any other person acting on its or their behalf (other than the Initial Purchasers, as to which no
statement is given) (x) have not made and will not make any offer relating to the Securities that, if the offering of the Securities contemplated by this Agreement were conducted as a public offering pursuant to a registration statement filed
under the Act with the Commission, would constitute an “issuer free writing prospectus,” as defined in Rule 433 under the Act (any such offer is hereinafter referred to as a “Company Supplemental Disclosure Document”) and
(y) have not solicited and will not solicit offers for, and have not offered or sold and will not offer or sell, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation
D other than any such solicitation listed on Schedule II(d) (each such solicitation, a “Permitted General Solicitation”; each written general solicitation document listed on Schedule II(d), a “Permitted General Solicitation
Material”); 

 (ii) each Purchaser, severally and not jointly, represents and agrees that, without the prior consent of
the Company and the Representatives, other than one or more term sheets relating to the Securities containing customary information and conveyed to purchasers of securities or any Permitted General Solicitation Material, it has not made and will not
make any offer relating to the Securities that, if the offering of the Securities contemplated by this Agreement were conducted as a public offering pursuant to a registration statement filed under the Act with the Commission, would constitute a
“free writing prospectus,” as defined in Rule 405 under the Act (any such offer (other than any such term sheets and any Permitted General Solicitation Material), is hereinafter referred to as a “Purchaser Supplemental Disclosure
Document”); and 
 (iii) any Company Supplemental Disclosure Document, Purchaser Supplemental Disclosure Document or Permitted General
Solicitation Material, the use of which has been consented to by the Company and the Representatives, is listed as applicable on Schedule II(b), Schedule II(c) or Schedule II(d) hereto, respectively; 

  
 12 









	7.	Additional Covenants of the Company. The Company covenants and agrees with the several Initial Purchasers that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses
of the Company’s counsel and accountants in connection with the issue of the Securities and the Underlying Common Stock and all other expenses in connection with the preparation, printing, reproduction and filing of the
Preliminary Offering Circular and the Offering Circular and any amendments and supplements thereto and the mailing and delivering of copies thereof to the Initial Purchasers and dealers; (ii) the cost of printing or producing any Agreement
among Purchasers, this Agreement, the Indenture, the Securities, the Blue Sky Memorandum, closing documents (including any compilations thereof), Permitted General Solicitation Materials and any other documents in connection with the offering,
purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities and the Underlying Common Stock for offering and sale under state securities laws as provided in Section 5(b) hereof,
including the fees and disbursements of counsel for the Initial Purchasers in connection with such qualification and in connection with the Blue Sky and legal investment surveys; (iv) any fees charged by securities rating services for rating
the Securities; (v) the cost of preparing the Securities; (vi) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Securities;

to the Maximum Number of Underlying Securities; and (ix) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section. It is understood, however, that,
except as provided in this Section, and Sections 9 and 12 hereof, the Initial Purchasers will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Securities by them, and any
advertising expenses connected with any offers they may make. 

  

	8.	Conditions of the Initial Purchasers’ Obligations. The obligations of the Initial Purchasers hereunder shall be subject, in their discretion, to the condition that all representations and
warranties and other statements of the Company herein are, at and as of each Time of Delivery, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the
following additional conditions: 

  

	 	(a)	Davis Polk & Wardwell LLP, counsel for the Initial Purchasers, shall have furnished to you such opinion or opinions, dated such Time of Delivery, with respect to such matters as you may reasonably request, and

 13 









	 	
with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as
set forth or contemplated in the Pricing Circular, and (ii) since the respective dates as of which information is given in the Pricing Circular there shall not have been any change in the capital stock or
long-term debt of the Company or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position,
stockholders’ equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Pricing Circular, the effect of which, in any such case described in clause (i) or (ii), is in your
judgment so material and adverse as to make it impracticable or inadvisable to proceed with the offering or the delivery of the Securities on the terms and in the manner contemplated in this Agreement and in each of the Pricing Disclosure Package
and the Offering Circular; 

  

	 	(e)	On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization”, as that
term is defined by the Commission in Section 3(a)(62) under the Exchange Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the
Company’s debt securities;

in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war or
(v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in your judgment makes it
impracticable or inadvisable to proceed with the offering or the delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package and the Offering Circular; 


 

	 	(g)	A number of shares of Common Stock equal to the Maximum Number of Underlying Securities shall have been duly listed, subject to notice of issuance, on the NASDAQ;

effect set forth in Exhibit A hereof; 

  

	 	(i)	The Initial Purchasers shall have received an executed original copy of the Indenture; 

  

	 	(j)	The Securities shall be eligible for clearance and settlement through the facilities of DTC; and

Company herein at and as of such Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such Time of Delivery, as to the matters set forth in subsection (e) of this Section and
as to such other matters as you may reasonably request. 


  
 14 









	9.	Indemnification. 

  

	 	(a)	The Company will indemnify and hold harmless each Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Initial Purchaser may become subject, under the Act or otherwise, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Circular, the Pricing
Circular, the Pricing Disclosure Package, the Offering Circular, or any amendment or supplement thereto, any Company Supplemental Disclosure Document, any Permitted General Solicitation Material or arise out of or are based upon the omission or
alleged omission to state therein a material fact necessary to make the statements therein not misleading, and will reimburse each Purchaser for any legal or other expenses reasonably incurred by such Initial Purchaser in connection with
investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or
is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Circular, the Pricing Circular, the Pricing Disclosure Package, the Offering Circular or any such amendment or
supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written information furnished to the Company by any Initial Purchaser through the Representatives
expressly for use therein, which information is limited to the information set forth in Section 9(f). 

  

	 	(b)	Each Purchaser, severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Circular, the Pricing Circular, the
Pricing Disclosure Package, the Offering Circular, or any amendment or supplement thereto, or any Company Supplemental Disclosure Document, any Permitted General Solicitation Material or arise out of or are based upon the omission or alleged
omission to state therein a material fact or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made
in any Preliminary Offering Circular, the Pricing Circular, the Pricing Disclosure Package, the Offering Circular or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in
reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representatives expressly for use therein, which information is limited to the information set forth in Section 9(f); and each
Purchaser will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. 


 

	 	(c)	 Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the
commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to
notify the indemnifying 



  
 15 









	 	
party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified
party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or
consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an
admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. 

  

	 	(d)	 If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an
indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial
Purchasers on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under
subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the
Company on the one hand and the Initial Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand and the Initial Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by
the Company bear to the total underwriting discounts and commissions received by the Initial Purchasers, in each case as set forth in the Offering Circular. The relative fault 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 on the one hand or the Initial Purchasers on the other and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this subsection (d) were
determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d).
The amount paid or 



  
 16 









	 	
payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include
any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any
amount in excess of the amount by which the total price at which the Securities purchased by it and distributed to investors were offered to investors exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged omission. The Initial Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not
joint. 

  

	 	(e)	The obligations of the Company under this Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to any affiliate of each
Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of the Act; and the obligations of the Initial Purchasers under this Section 9 shall be in addition to any liability which the respective Purchasers may
otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act. 


 

	 	(f)	The Initial Purchasers severally confirm and the Company acknowledges and agrees that the statement appearing in the third sentence of the second paragraph under the caption “Plan of Distribution” and the
statements regarding stabilization, syndicate covering transactions and penalty bids appearing in the first two sentences of the sixth paragraph and in the first sentence of the seventh paragraph under the caption “Plan of Distribution” in
the Pricing Disclosure Package and the Offering Circular are correct and constitute the only information concerning such Initial Purchasers furnished in writing to the Company by or on behalf of the Initial Purchasers expressly for use in any
Preliminary Offering Circular, the Pricing Circular, the Pricing Disclosure Package, the Offering Circular or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material.


  

	10.	Termination. 

  

	 	(a)	If any Purchaser shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such
Securities on the terms contained herein. If within thirty-six hours after such default by any Purchaser you do not arrange for the purchase of such Securities, then the Company shall be entitled to a further
period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you
notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies you that it has so arranged for the purchase of such Securities, you or the Company shall have the right to postpone the applicable Time of
Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Offering Circular, or in any other documents or arrangements, and the Company agrees to prepare promptly any amendments or
supplements to the Offering Circular which in your opinion may thereby be made necessary. The term “Initial Purchaser” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had
originally been a party to this Agreement with respect to such Securities. 


  
 17 









	 	(b)	If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser(s) by you and the Company as provided in subsection (a) above, the aggregate principal amount of such
Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each
non-defaulting Purchaser to purchase the principal amount of Securities which such Initial Purchaser agreed to purchase hereunder and, in addition, to require each
non-defaulting Initial Purchaser to purchase its pro rata share (based on the principal amount of Securities which such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting
Initial Purchaser(s) for which such arrangements have not been made; but nothing herein shall relieve a defaulting Initial Purchaser from liability for its default. 


If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Company
as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company
shall not exercise the right described in subsection (b) above to require non-defaulting Purchasers to purchase Securities of a defaulting Purchaser or Purchasers, then this Agreement shall thereupon
terminate, without liability on the part of any non-defaulting Purchaser or the Company, except for the expenses to be borne by the Company and the Initial Purchasers as provided in Section 6 hereof and
the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Purchaser from liability for its default. 
  

	11.	Survival. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Initial Purchasers, as set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Initial Purchaser or any controlling person of any
Initial Purchaser, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities. 

  


	12.	Effect of Termination. If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Initial Purchaser except as provided in Sections 7
and 9 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Initial Purchasers through you for all expenses approved in writing by you, including fees
and disbursements of counsel, reasonably incurred by the Initial Purchasers in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Initial Purchaser except as
provided in Sections 7 and 9 hereof. 

  

	13.	No Advisory or Fiduciary Relationship; Notices; U.S. Patriot Act. In all dealings hereunder, you shall act on behalf of each of the Initial Purchasers, and the parties hereto shall be entitled to act and rely
upon any statement, request, notice or agreement on behalf of any Initial Purchaser made or given by the Representatives. 


All statements, requests, notices and agreements hereunder shall be in writing, and if to the Initial Purchasers shall be delivered or sent by
mail or facsimile transmission to you as the Representatives at Goldman, Sachs & Co., 200 West Street, New York, New York 10282-2198, Attention: Registration 

  
 18 








 
Department and Wells Fargo Securities, LLC, 375 Park Avenue, New York, New York 10152, Attention: Equity Syndicate Department (Fax: (212) 214-5918); and if
to the Company shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Offering Circular, Attention: Secretary; provided, however, that any notice to an Initial Purchaser pursuant to
Section 9 hereof shall be delivered or sent by mail or facsimile transmission to such Initial Purchaser at its address set forth in its Purchasers’ Questionnaire, which address will be supplied to the Company by you upon request. Any such
statements, requests, notices or agreements shall take effect upon receipt thereof. 
 In accordance with the requirements of the USA
Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients,
including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients. 

 

	14.	Parties. This Agreement shall be binding upon, and inure solely to the benefit of, the Initial Purchasers, the Company and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the
Company and each person who controls the Company or any Initial Purchaser, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No
purchaser of any of the Securities from any Initial Purchaser shall be deemed a successor or assign by reason merely of such purchase. 

  

	15.	Time is of the Essence. Time shall be of the essence of this Agreement. 

  

	16.	No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an
arm’s-length commercial transaction between the Company, on the one hand, and the several Initial Purchasers, on the other, (ii) in connection therewith and with the process leading to such
transaction each Purchaser is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Purchaser has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering
contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth
in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Initial Purchasers, or any of them, have rendered advisory
services of any nature or respect, or owe a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto. 

  

	17.	Full Agreement. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Initial Purchasers, or any of them, with respect to the subject
matter hereof. 

  

	18.	GOVERNING LAW. THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF
LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK. The Company agrees that any suit or proceeding arising in respect of this agreement or our engagement will be tried exclusively in the U.S. District
Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company agrees to submit to the jurisdiction of, and to venue in,
such courts. 


  
 19 









	19.	No Trial by Jury. The Company and each of the Initial Purchasers hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising
out of or relating to this Agreement or the transactions contemplated hereby. 

  

	20.	Counterparts. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall
together constitute one and the same instrument. 

  

	21.	Notwithstanding anything herein to the contrary, the Company (and the Company’s employees, representatives, and other agents) are authorized to disclose to any and all persons, the tax treatment and tax structure
of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Initial Purchasers’ imposing any limitation of any kind.
However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax
treatment” means US federal and state income tax treatment, and “tax structure” is limited to any facts that may be relevant to that treatment. 


If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this
instrument, along with all counterparts, will become a binding agreement among the Initial Purchasers and the Company in accordance with its terms.
