Huron Consulting Group Inc., a Delaware corporation (the “Company”), confirms its agreement with Merrill Lynch, Pierce,
Fenner & Smith Incorporated (“Merrill Lynch”) and each of the other Initial Purchasers named in Schedule A hereto (collectively, the “Initial Purchasers,” which term shall also include any initial purchaser substituted
as hereinafter provided in Section 11 hereof), for whom Merrill Lynch and J.P. Morgan Securities LLC (“J.P. Morgan”) are acting as representatives (in such capacity, the “Representatives”), with respect to (i) the sale
by the Company and the purchase by the Initial Purchasers, acting severally and not jointly, of the respective principal amounts set forth in said Schedule A of $225,000,000 aggregate principal amount of the Company’s 1.25% Convertible
Senior Notes due 2019 (the “Initial Securities”) and (ii) the grant by the Company to the Initial Purchasers, acting severally and not jointly, of the option to purchase all or any part of an additional $25,000,000 aggregate principal
amount of its 1.25% Convertible Senior Notes due 2019 (the “Option Securities” and, together with the Initial Securities, the “Securities”). The Securities are to be issued pursuant to an indenture, to be dated as of
September 10, 2014 (the “Indenture”), between the Company and U.S. Bank National Association as trustee (the “Trustee”). 

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth
herein and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (“Subsequent Purchasers”) at any time after this Agreement has been executed and
delivered. The Securities are to be offered and sold through the Initial Purchasers without being registered under the Securities Act of 1933, as amended (the “1933 Act”), in reliance upon exemptions therefrom. Pursuant to the terms
of the Securities and the Indenture, investors that acquire Securities may only resell or otherwise transfer such Securities if such Securities are hereafter registered under the 1933 Act or if an exemption from the registration requirements of
the 1933 Act is available (including the exemption afforded by Rule 144A (“Rule 144A”) of the rules and regulations promulgated under the 1933 Act (the “1933 Act Regulations”) by the Securities and Exchange
Commission (the “Commission”)). 

 The Company has prepared and delivered to each Initial Purchaser copies of a preliminary offering
memorandum dated September 3, 2014 prior to the Applicable Time (as defined below) (the “Preliminary Offering Memorandum”) and has prepared and will deliver to each Initial Purchaser, on the date hereof or the next succeeding business
day, copies of a final offering memorandum dated September 4, 2014 (the “Final Offering Memorandum”), each for use by such Initial Purchaser in connection with its solicitation of purchases of, or offering of, the Securities.
“Offering Memorandum” means, with respect to any date or time referred to in this Agreement, the most recent offering memorandum (whether the Preliminary Offering Memorandum or the Final Offering Memorandum, or any amendment or supplement
to either such document), including exhibits thereto and any documents incorporated therein by reference, which has been prepared and delivered by the Company to the Initial Purchasers, in the case of the Preliminary Offering Memorandum prior to the
Applicable Time, in connection with their solicitation of purchases of, or offering of, the Securities. The Company will prepare a final term sheet reflecting the final terms of the Securities, in the form set forth in Schedule B hereto (the
“Final Term Sheet”), and will deliver such Final Term Sheet to the Initial Purchasers prior to the Applicable Time in connection with their solicitation of purchases of, or offering of, the Securities. The Company agrees that, unless it
obtains the prior written consent of the Representatives, it will not make any offer relating to the Securities by any written materials other than the Offering Memorandum and the Issuer Written Information. “Issuer Written Information”
means (i) any writing intended for general distribution to investors as evidenced by its being specified in Schedule C hereto, including the Final Term Sheet, and (ii) any “road show” that is a “written communication”
within the meaning of the 1933 Act. “General Disclosure Package” means the Preliminary Offering Memorandum and any Issuer Written Information specified on Schedule C hereto and issued at or prior to 8:00 A.M., New York City time, on
September 5, 2014 or such other time as agreed by the Company and Merrill Lynch (such date and time, the “Applicable Time”). 

All references in this Agreement to financial statements and schedules and other information which is “contained,”
“included” or “stated” in the Offering Memorandum (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which are incorporated by reference in
the Offering Memorandum; and all references in this Agreement to amendments or supplements to the Offering Memorandum shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934 (the
“1934 Act”) which is incorporated by reference in the Offering Memorandum. 
 SECTION 1. Representations and
Warranties. 
 (a) Representations and Warranties by the Company. The Company represents and warrants to each Initial Purchaser as
of the date hereof, the Applicable Time, the Closing Time and any Date of Delivery (as defined below), and agrees with each Initial Purchaser, as follows: 

(i) General Disclosure Package; Rule 144A Eligibility. The Company hereby confirms that it has authorized the use
of the General Disclosure Package, including the Preliminary Offering Memorandum and the Final Term Sheet, and the Final Offering Memorandum in connection with the offer and sale of the Securities by the Initial Purchasers. The Securities are
eligible for resale pursuant to Rule 144A and will not be, at the Closing Time, of the same class as securities of the Company listed on a national securities exchange registered under Section 6 of the 1934 Act, or quoted in a U.S.
automated interdealer quotation system. 
 (ii) No Registration Required; No General Solicitation. Subject to
compliance by the Initial Purchasers with the representations and warranties of the Initial Purchasers and the procedures set forth in Section 6 hereof, it is not necessary in connection with the offer, sale and delivery of the offered
Securities to the Initial Purchasers and to each Subsequent Purchaser who 

  
 2 

 
purchases the Securities from the Initial Purchaser in the initial resale of such Securities by the Initial Purchaser in the manner contemplated by this Agreement, the General Disclosure Package
and the Final Offering Memorandum to register the Securities under the 1933 Act or to qualify the Indenture under the Trust Indenture Act of 1939, as amended (the “1939 Act”). None of the Company, its Affiliates or any person acting
on its or any of their behalf (other than the Initial Purchasers, as to whom the Company makes no representation) has engaged, in connection with the offering of the offered Securities, in any form of general solicitation or general advertising
within the meaning of Rule 502(c) under the 1933 Act Regulations. 
 (iii) Accurate Disclosure. As of the
Applicable Time, neither (A) the General Disclosure Package nor (B) any Issuer Written Information, when considered together with the General Disclosure Package, included, includes or will include an untrue statement of a material fact or
omitted, omits or will 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. The Final Offering Memorandum, as of its date, at the Closing Time
or at any Date of Delivery, did not, does not and will not 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. The documents incorporated or deemed to be incorporated by reference in the General Disclosure Package and the Final Offering Memorandum, when such documents incorporated by reference were filed with the Commission, when read
together with the other information in the General Disclosure Package or the Final Offering Memorandum, as the case may be, did not, does not and will not 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. 
 The
representations and warranties in this subsection shall not apply to statements in or omissions from the General Disclosure Package or the Final Offering Memorandum made in reliance upon and in conformity with written information furnished to the
Company by any Initial Purchaser through Merrill Lynch expressly for use therein. For purposes of this Agreement, the only information so furnished shall be the information in the first paragraph under the heading “Plan of
Distribution–Price Stabilization, Short Positions” in the Offering Memorandum (collectively, the “Initial Purchaser Information”). 

(iv) Incorporation of Documents by Reference. The documents incorporated or deemed to be incorporated by reference in
the Offering Memorandum at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission under the 1934 Act (the
“1934 Act Regulations”). 
 (v) Independent Accountants. The accountants who certified the financial
statements and supporting schedules included in the Offering Memorandum are independent public accountants with respect to the Company and its consolidated subsidiaries as required by the 1933 Act, the 1933 Act Regulations, the 1934 Act, the 1934
Act Regulations and the Public Company Accounting Oversight Board. 
 (vi) Financial Statements; Non-GAAP Financial
Measures. The financial statements included or incorporated by reference in the General Disclosure Package and the Final Offering Memorandum, together with the related schedules and notes, present fairly, in all material respects, the financial
position of the Company and its consolidated subsidiaries at the dates indicated and the statement of operations, stockholders’ equity and cash flows of the Company and its consolidated subsidiaries for the periods specified; said financial
statements have been 

  
 3 

 
prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), in all material respects, applied on a consistent basis throughout the periods involved. The
supporting schedules, if any, present fairly in accordance with GAAP the information required to be stated therein, in all material respects. The selected financial data and the summary financial information included in the Offering Memorandum
present fairly, in all material respects, the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included therein. No historical or pro forma financial statements or supporting
schedules are required to be included or incorporated by reference in the Offering Memorandum under the 1933 Act or the 1933 Act Regulations. All disclosures contained in the General Disclosure Package or the Final Offering Memorandum, or
incorporated by reference therein, regarding “non-GAAP financial measures” (as such term is defined by the rules and regulations of the Commission) comply with Regulation G of the 1934 Act and Item 10 of Regulation S-K of the 1933
Act, to the extent applicable. The interactive data in eXtensible Business Reporting Language incorporated by reference in the General Disclosure Package and the Final Offering Memorandum fairly presents the information called for in all material
respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto.

enter into and perform its obligations under this Agreement; and the Company is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by
reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not reasonably be expected to result in a Material Adverse Effect. 

(ix) Good Standing of Subsidiaries. Each “significant subsidiary” of the Company (as such term is defined in
Rule 1-02 of Regulation S-X) (each, a “Subsidiary” and, collectively, the “Subsidiaries”) has been duly organized and is validly existing in good standing under the laws of the jurisdiction of its incorporation or organization,

delivered by the Company. 
 (xii) Authorization of the Indenture. The Indenture has been duly authorized by the
Company and, when duly executed and delivered by the Company and the Trustee, will constitute a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be

(xiii) Authorization of the Securities and the Common Stock. The Securities have been duly authorized and, at the
Closing Time, will have been duly executed by the Company and, when authenticated, issued and delivered in the manner provided for in the Indenture and delivered against payment of the purchase price therefor as provided in this Agreement, will

obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which
it or any of them may be bound or to which any of the properties or assets of the Company or any subsidiary is subject (collectively, “Agreements and Instruments”), except for such defaults that would not, singly or in the aggregate,

or in the aggregate, reasonably be expected to result in a Material Adverse Effect. The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated herein and in the General Disclosure Package and the
Final Offering Memorandum (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described therein under the caption “Use of Proceeds”) and compliance by the Company with its
obligations hereunder have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment
Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any properties or assets of the Company or any subsidiary pursuant to, the Agreements and Instruments (except for such conflicts,
breaches, defaults or Repayment Events or liens, charges or encumbrances that would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect); nor will such action result in any violation of (i) the
provisions of the charter, by-laws or similar organizational document of the Company or any of its subsidiaries or (ii) any law, statute, rule, regulation, judgment, order, writ or decree of any Governmental Entity, except, in the case of this
clause (ii), for such violations of any law, statute, rule, regulation, judgment, order, writ or decree (other than (x) federal securities laws, regulations and rules and (y) judgments, orders, writs or decrees thereunder) as would not,
singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or
any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of its subsidiaries. 

(xvii) Absence of Labor Dispute. No labor dispute with the employees of the Company or any of its subsidiaries exists

Disclosure Package and the Final Offering Memorandum, there is no action, suit, proceeding, inquiry or investigation before or brought by any Governmental Entity now pending or, to the knowledge of the Company, threatened, against or affecting the
Company or any of its subsidiaries, which would, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect, or which would, singly or in the aggregate, reasonably be expected to materially and adversely affect their
respective properties or assets or the consummation of the transactions contemplated in this Agreement or the performance by the Company of its obligations hereunder; and the aggregate of all pending legal or governmental proceedings to which the
Company or any such subsidiary is a party or of which any of their respective properties or assets is the subject which are not described in the General Disclosure Package and the Final Offering Memorandum, including ordinary routine litigation
incidental to the business, would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. 

(xix) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order,
registration, qualification or decree of, any Governmental Entity is necessary or required for the performance by the Company of its obligations hereunder, in connection with the offering, issuance or sale of the Securities hereunder or the
consummation of the transactions contemplated by this Agreement or for the due execution, delivery and performance of the Indenture, except (A) such as have been already obtained, (B) such as may be required under the securities or
“Blue Sky” laws of U.S. state or non-U.S. jurisdictions or other non-U.S. laws applicable to the purchase of the Securities outside the United States in connection with the transactions contemplated hereby, (C) the filing of a current
report on Form 8-K with the Commission under the 1934 Act regarding the transactions contemplated hereby, which the Company covenants it will timely file under the 1934 Act or (D) those the failure to obtain would not, singly or in the
aggregate, reasonably be expected to (i) result in a Material Adverse Effect or (ii) materially and adversely affect the consummation of the transactions contemplated in this Agreement or the performance by the Company of its obligations
hereunder. 
 (xx) Possession of Licenses and Permits. Except as would not, singly or in the aggregate, reasonably be
expected to result in a Material Adverse Effect, the Company and its subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate Governmental
Entities necessary to conduct the business now operated by them. The Company and its subsidiaries are in compliance with the terms and conditions of all Governmental Licenses, except where the failure so to comply would not, singly or in the
aggregate, reasonably be expected to result in a Material Adverse Effect. All of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses
to be in full force and effect would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or
modification of any Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to result in a Material Adverse Effect. 

(xxi) Title to Property. The Company and its subsidiaries do not own any real property. The Company and its subsidiaries
have good title to all other properties owned by them, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind except such as (A) are described in the General
Disclosure Package and the Final Offering Memorandum or (B) do not, singly or in the aggregate, materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the
Company or any of its subsidiaries; and all of the leases and subleases material to the business of the Company and its subsidiaries, considered as one enterprise, and under which the Company or any of its subsidiaries holds properties described in
the General Disclosure Package and the Final Offering Memorandum, are 

  
 7 

 
in full force and effect; and neither the Company nor any such subsidiary has any notice of any claim of any sort that has been asserted by anyone adverse to the rights of the Company or any
subsidiary under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or such subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease except for any
claims which would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. 
 (xxii)

trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary
to carry on the business currently operated by them, except where such failure to own or possess, or such inability to acquire on reasonable terms, would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect;
and neither the Company nor any of its subsidiaries has received any notice or is otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which
would render any Intellectual Property invalid or inadequate to protect the interest of the Company or any of its subsidiaries therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity
or inadequacy, singly or in the aggregate, would reasonably be expected to result in a Material Adverse Effect. 
 (xxiii)
Environmental Laws. Except as described in the General Disclosure Package and the Final Offering Memorandum or would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect, (A) neither the Company
nor any of its subsidiaries is in violation of any applicable federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any

against or affecting the Company or any of its subsidiaries relating to Hazardous Materials or any applicable Environmental Laws. 

(xxiv) Accounting Controls and Disclosure Controls. The Company and each of its subsidiaries maintain effective internal
control over financial reporting (as defined under Rule 13-a15 and 15d-15 under the 1934 Act Regulations) and a system of internal accounting controls sufficient to
provide reasonable assurances that (A) transactions are executed in accordance with management’s general or specific authorization; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity

 8

or not remediated) and (2) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The
Company and each of its subsidiaries maintain an effective system of disclosure controls and procedures (as defined in Rule 13a-15 and Rule 15d-15 under the 1934 Act
Regulations) that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the

regarding disclosure. 
 (xxv) Compliance with the Sarbanes-Oxley Act. There is and, since January 1, 2010, has

regulations promulgated in connection therewith, including Section 402 related to loans and Sections 302 and 906 related to certifications. 

(xxvi) Payment of Taxes. All United States federal income tax returns of the Company and its subsidiaries required by
law to be filed have been filed and all taxes shown by such returns or otherwise assessed, which are due and payable, have been paid, except assessments against which appeals have been or will be promptly taken and as to which adequate reserves have
been provided. The United States federal income tax returns of the Company through the fiscal year ended December 31, 2012 have been settled and no assessment in connection therewith has been made against the Company. The Company and its
subsidiaries have filed all other tax returns that are required to have been filed by them pursuant to applicable foreign, state, local or other law except insofar as the failure to file such returns would not reasonably be expected to result in a
Material Adverse Effect, and has paid all taxes shown by such returns or pursuant to any assessment received by the Company and its subsidiaries, except for such taxes, if any, as are being contested in good faith and as to which adequate reserves
have been established by the Company. The charges, accruals and reserves on the books of the Company in respect of any income and corporation tax liability for any years not finally determined are adequate to meet any assessments or re-assessments
for additional income tax for any years not finally determined, except to the extent of any inadequacy that would not reasonably be expected to result in a Material Adverse Effect. 

(xxvii) Insurance. The Company and its subsidiaries carry or are entitled to the benefits of insurance, with insurers
that the Company reasonably believes are financially sound and reputable, in such amounts and covering such risks as is generally maintained by companies of established repute engaged in the same or similar business, and all such insurance is in

institutions as may be necessary or appropriate to 

  
 9 

 
conduct its business as now conducted and at a cost that would not result in a Material Adverse Change. Neither of the Company nor any of its subsidiaries has been denied any insurance coverage
which it has sought or for which it has applied, except for such denials that would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

of 1940, as amended (the “1940 Act”). 
 (xxix) Absence of Manipulation. Neither the Company nor any
Affiliate of the Company has taken, nor will the Company or any Affiliate take, directly or indirectly, any action which is designed, or would be expected, to cause or result in, or which constitutes, the stabilization or manipulation of the price

SECTION 2. Sale and Delivery to Initial Purchasers; Closing. 

(a) Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions
herein set forth, the Company agrees to sell to each Initial Purchaser, severally and not jointly, and each Initial Purchaser, severally and not jointly, agrees to purchase from the Company, at the price set forth in Schedule A, the aggregate
principal amount of Initial Securities set forth in Schedule A, plus any additional principal amount of Initial Securities which such Initial Purchaser may become obligated to purchase pursuant to the provisions of Section 11 hereof, subject to
such adjustments as Merrill Lynch in its discretion shall make to ensure that any sales or purchases are in authorized denominations. 

  
 11 

 (b) Option Securities. In addition, on the basis of the representations and warranties
herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Initial Purchasers, severally and not jointly, to purchase the Option Securities, at the price set forth in Schedule A. The option
hereby granted may be exercised in whole or in part from time to time upon notice by the Representatives to the Company setting forth the amount of Option Securities as to which the several Initial Purchasers are then exercising the option and the
time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representatives, but shall not be later than seven full business days after the exercise
of said option, nor in any event prior to the Closing Time, and shall be within a period of thirteen (13) days beginning from, and including, the date of the Closing Time. If the option is exercised as to all or any portion of the Option
Securities, each of the Initial Purchasers, acting severally and not jointly, will purchase that proportion of the total principal amount of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A
opposite the name of such Initial Purchaser bears to the total principal amount of Initial Securities, subject in each case to such adjustments as Merrill Lynch in its discretion shall make to ensure that any sales or purchases are in authorized
denominations. 
 (c) Payment. Payment of the purchase price for, and delivery of the Initial Securities (which will be represented by
one or more definitive global Securities in book-entry form that will be deposited by or on behalf of the Company with DTCC (as defined below) or its designated custodian) shall be made at the offices of
Latham & Watkins LLP at 885 Third Avenue, New York, New York 10022, or at such other place as shall be agreed upon by the Representatives and the Company, at 9:00 A.M. (New York City time) on the third (fourth, if the pricing occurs
after 4:30 P.M. (New York City time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 11), or such other time not later than ten business days after such date as shall be agreed
upon by the Representatives and the Company (such time and date of payment and delivery being herein called “Closing Time”). 
 In
addition, in the event that any or all of the Option Securities are purchased by the Initial Purchasers, payment of the purchase price for, and delivery such Option Securities (which will be represented by one or more definitive global Securities in
book-entry form that will be deposited by or on behalf of the Company with DTCC (as defined below) or its designated custodian) shall be made at the above-mentioned
offices, or at such other place as shall be agreed upon by the Representatives and the Company, on each Date of Delivery as specified in the notice from Merrill Lynch to the Company. 

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against
delivery to the Representatives for the respective accounts of the Initial Purchasers of certificates for the Securities to be purchased by them. It is understood that each Initial Purchaser has authorized the Representatives, for its account, to
accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. Merrill Lynch, individually and not as Representatives, may (but shall not be
obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Initial Purchaser whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the
case may be, but such payment shall not relieve such Initial Purchaser from its obligations hereunder. 
 SECTION 3. Covenants of the
Company. The Company covenants with each Initial Purchaser as follows: 
 (a) Delivery of Offering Memorandum. The Company has
delivered to each Initial Purchaser, without charge, as many copies of the Preliminary Offering Memorandum (as amended or supplemented) thereto and documents incorporated by reference therein as such Initial Purchaser

  
 12 

 
reasonably requested, and the Company hereby consents to the use of such copies. The Company will furnish to each Initial Purchaser, without charge, such number of copies of the Final Offering
Memorandum thereto and documents incorporated by reference therein as such Initial Purchaser may reasonably request. 
 (b) Notice and
Effect of Material Events. If at any time prior to the completion of resales of the Securities by the Initial Purchasers, any event shall occur or condition shall exist as a result of which it is necessary, in the reasonable opinion of counsel
for the Initial Purchasers or for the Company, to amend or supplement the General Disclosure Package or the Final Offering Memorandum in order that the General Disclosure Package or the Final Offering Memorandum, as the case may be, will not include
any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a Subsequent Purchaser, the Company
will promptly (A) give the Representatives notice of such event and (B) prepare any amendment or supplement as may be necessary to correct such statement or omission and, a reasonable amount of time prior to any proposed use or
distribution, furnish the Representatives with copies of any such amendment or supplement; provided that the Company shall not use or distribute any such amendment or supplement to which the Representatives or counsel for the Initial Purchasers
shall object. The Company will furnish to the Initial Purchasers such number of copies of such amendment or supplement as the Initial Purchasers may reasonably request. 

(c) Reporting Requirements. Until the completion of the initial resales of the Securities by the Initial Purchasers, the Company will
file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations. The Company has given the Representatives notice of any filings made pursuant to the
1934 Act or 1934 Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representatives notice of its intention to make any such filing from the Applicable Time to the Closing Time and will furnish the
Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Initial Purchasers shall
reasonably object. 
 (d) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Initial Purchasers,
to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications in effect so long as required
to complete the distribution of the Securities; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in
which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. 

(e) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the
General Disclosure Package and the Final Offering Memorandum under “Use of Proceeds.” 
 (f) DTCC. The Company will
cooperate with the Initial Purchasers and use its reasonable efforts to permit the offered Securities to be eligible for clearance and settlement through the facilities of The Depository Trust & Clearing Corporation (“DTCC”). 

(g) Listing. For so long as the Company’s Common Stock is then listed on the Nasdaq Global Select Market, the Company will use its
best efforts to effect and maintain the listing of the Common Stock issuable upon conversion of the Securities on the Nasdaq Global Select Market.

under the 1933 Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common

Securities to be sold hereunder, (B) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the General Disclosure Package and
the Final Offering Memorandum or (C) any shares of Common Stock issued, options to purchase Common Stock granted or other equity incentive awards granted pursuant to existing employee benefit plans of the Company referred to in the General
Disclosure Package and the Final Offering Memorandum, and any shares of Common Stock issued in respect of such awards.

SECTION 6. Subsequent Offers and Resales of the Securities. 

(a) Offer and Sale Procedures. Each of the Initial Purchasers and the Company hereby establish and agree to observe the following
procedures in connection with the offer and sale of the Securities: 
 (i) Offers and Sales. Offers and sales
of the Securities shall be made to such persons and in such manner as is contemplated by the Offering Memorandum. Each Initial Purchaser severally agrees that it will not offer, sell or deliver any of the Securities in any jurisdiction outside the
United States except under circumstances that will result in compliance with the applicable laws thereof, and that it will take at its own expense whatever action is required to permit its purchase and resale of the Securities in such jurisdictions.
The Company has not entered into any contractual arrangement, other than this Agreement, with respect to the distribution of the Securities or the Common Stock issuable upon conversion of the Securities and the Company will not enter into any such
arrangement except as contemplated thereby. 
 (ii) No General Solicitation. No general solicitation or general
advertising (within the meaning of Rule 502(c) under the 1933 Act Regulations) will be used in the United States in connection with the offering or sale of the Securities. 

(iii) Legends. Each of the Securities will bear, to the extent applicable, the legend contained in “Notice to
Investors” in the General Disclosure Package and the Final Offering Memorandum for the time period and upon the other terms stated therein. 

(iv) Minimum Principal Amount. No sale of the Securities to any one Subsequent Purchaser will be for less than U.S.
$1,000 principal amount and no Security will be issued in a smaller principal amount. 
 (b) Covenants of the Company. The Company
covenants with each Initial Purchaser as follows: 
 (i) Integration. The Company agrees that it will not and will
cause its Affiliates not to, directly or indirectly, solicit any offer to buy, sell or make any offer or sale of, or otherwise negotiate in respect of, securities of the Company of any class if, as a result of the doctrine of “integration”
referred to in Rule 502 under the 1933 Act Regulations, such offer or sale would render invalid (for the purpose of (i) the sale of the offered Securities by the Company to the Initial Purchasers, (ii) the resale of the offered
Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the offered Securities by such Subsequent Purchasers to others) the exemption from the registration requirements of the 1933 Act provided by
Section 4(a)(2) thereof or by Rule 144A thereunder or otherwise. 
 (ii) Rule 144A Information. The Company
agrees that, in order to render the offered Securities eligible for resale pursuant to Rule 144A, while any of the offered Securities remain outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under
the 1933 Act, it will make available, upon request, to any holder of offered Securities or prospective purchasers of Securities the information specified in Rule 144A(d)(4), unless the Company furnishes information to the Commission pursuant to
Section 13 or 15(d) of the 1934 Act. 

  
 17 

 (iii) Restriction on Repurchases. Until the expiration of one year after
the original issuance of the offered Securities, the Company will not, and will cause its Affiliates not to, resell any offered Securities which are reacquired by such persons which are “restricted securities” (as such term is defined
under Rule 144(a)(3)), whether as beneficial owner or otherwise (except as agent acting as a securities broker on behalf of and for the account of customers in the ordinary course of business in unsolicited broker’s transactions). 

(c) Representations, Warranties and Agreements of the Initial Purchasers. Each Initial Purchaser severally and not jointly represents
and warrants to, and agrees with, the Company that it is a Qualified Institutional Buyer and an “accredited investor” within the meaning of Rule 501(a) under the 1933 Act Regulations. Each Initial Purchaser understands that the
offered Securities have not been and will not be registered under the 1933 Act and may not be offered or sold within the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of
the 1933 Act. Each Initial Purchaser severally represents and agrees that it has not offered or sold, and will not offer or sell, any offered Securities constituting part of its allotment within the United States except in accordance with
Rule 144A or another applicable exemption from the registration requirements of the 1933 Act. Accordingly, neither it nor any person acting on its behalf has made or will make offers or sales of the Securities in the United States by means
of any form of general solicitation or general advertising (within the meaning of Regulation D) in the United States. Each Initial Purchaser will take reasonable steps to inform, and cause each of its affiliates (as such term is defined in Rule
501(b) under the 1933 Act Regulations (each, an “Affiliate”)) to take reasonable steps to inform, persons acquiring Securities from such Initial Purchaser or Affiliate, as the case may be, in the United States that the Securities
(A) have not been and will not be registered under the 1933 Act, (B) are being sold to them without registration under the 1933 Act in reliance on Rule 144A or in accordance with another exemption from registration under the
1933 Act, as the case may be, and (C) may not be offered, sold or otherwise transferred except (1) to the Company, (2) outside the United States in accordance with Regulation S or (3) inside the United States in
accordance with (x) Rule 144A to a person whom the seller reasonably believes is a Qualified Institutional Buyer that is purchasing such Securities for its own account or for the account of a Qualified Institutional Buyer to whom notice is
given that the offer, sale or transfer is being made in reliance on Rule 144A or (y) pursuant to another available exemption from registration under the 1933 Act. 

SECTION 7. Indemnification. 

(a) Indemnification of Initial Purchasers. The Company agrees to indemnify and hold harmless each Initial Purchaser, its Affiliates, its
selling agents and their respective officers and directors and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows: 

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement
or alleged untrue statement of a material fact included in any Preliminary Offering Memorandum, the Final Offering Memorandum, the information contained in the Final Term Sheet, any Issuer Written Information, any “road show” (as defined
in Rule 433 under the 1933 Act) not constituting Issuer Written Information or any other information used by or on behalf of the Company in connection with the offer or sale of the Securities (or any amendment or supplement to the foregoing) or the
omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; 

  
 18 

 (ii) against any and all loss, liability, claim, damage and expense whatsoever,
as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement
or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company; and 

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill
Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement
or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under clauses (i) or (ii) above; 

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in any Preliminary Offering Memorandum, the Final Offering Memorandum or the information contained in the Final Term Sheet (or any amendment or supplement to the foregoing) in
reliance upon and in conformity with the Initial Purchaser Information. 
 (b) Indemnification of Company, Directors and Officers.
Each Initial Purchaser severally agrees to indemnify and hold harmless the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934
Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in any Preliminary Offering Memorandum, the Final Offering Memorandum or the information contained in the Final Term Sheet (or any amendment or supplement to the foregoing) in reliance upon and in conformity with the Initial
Purchaser Information. 
 (c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability
hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant
to Section 7(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Company. In
no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar
or related actions in the same jurisdiction arising out of the same general allegations or circumstances, unless the indemnifying party and the indemnified party shall have mutually agreed to the contrary. An indemnifying party may participate at
its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. Any indemnified party shall have the
right to retain its own counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the
contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses
available to it that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified
party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. No indemnifying party shall, without the prior written 

  
 19 

 
consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding 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) Settlement
without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable
for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request,
(ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement. 
 SECTION 8. Contribution. If the indemnification provided for in
Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the
aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) 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 hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such
losses, liabilities, claims, damages or expenses, 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 hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the
offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Initial Purchasers, on the other hand, bear to the aggregate initial
offering price of the Securities as set forth on the cover of the Final Offering Memorandum. 
 The relative fault of the Company, on the
one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or by the Initial Purchasers 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 Section 8 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 Section 8.
The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or
omission or alleged omission. 

  
 20 

 Notwithstanding the provisions of this Section 8, no Initial 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 the public were offered to the public exceeds the amount of any damages that such Initial Purchaser has otherwise been
required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. 
 No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 

For purposes of this Section 8, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the 1933
Act or Section 20 of the 1934 Act and each Initial Purchaser’s Affiliates and selling agents shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, each officer of the Company, and each
person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Initial Purchasers’ respective obligations to
contribute pursuant to this Section 8 are several in proportion to the aggregate principal amount of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint. 

SECTION 9. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Initial Purchaser
or its Affiliates or selling agents, any person controlling any Initial Purchaser, its officers or directors or any person controlling the Company and (ii) delivery of and payment for the Securities. 

SECTION 10. Termination of Agreement. 

(a) Termination. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time
(i) if there has been, in the judgment of the Representatives, since the time of execution of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Final Offering Memorandum, any
material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business,
or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or
development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to
proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the Nasdaq Global Select
Market, or (iv) if trading generally on the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been
required, by any of said exchanges or by order of the Commission, the Financial Industry Regulatory Authority, Inc. or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or
clearance services in the United States, or (vi) if a banking moratorium has been declared by either Federal or New York authorities. 

  
 21 

 (b) Liabilities. If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 7, 8, 9, 14, 15, 16 and 17 shall survive such termination and remain in full force and effect.

 SECTION 11. Default by One or More of the Initial Purchasers. If one or more of the Initial Purchasers shall fail at the Closing
Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 36 hours thereafter, to make
arrangements for one or more of the non-defaulting Initial Purchasers, or any other initial purchasers, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon
and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 36-hour period, then: 

(i) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be
purchased on such date, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting
obligations hereunder bear to the underwriting obligations of all non-defaulting Initial Purchasers, or 

(ii) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased on
such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Initial Purchasers to purchase, and the Company to sell, the Option Securities to be purchased and sold on such Date of
Delivery, shall terminate without liability on the part of any non-defaulting Initial Purchaser. 

No action taken pursuant to this Section shall relieve any defaulting Initial Purchaser from liability in respect of its default. 

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after
the Closing Time, which does not result in a termination of the obligation of the Initial Purchasers to purchase and the Company to sell the relevant Option Securities, as the case may be, either the (i) Representatives or (ii) the Company
shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the General Disclosure Package or the Final Offering Memorandum or
in any other documents or arrangements. As used herein, the term “Initial Purchaser” includes any person substituted for an Initial Purchaser under this Section 11. 

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if
mailed or transmitted by any standard form of telecommunication. Notices to the Initial Purchasers shall be directed to Merrill Lynch at One Bryant Park, New York, New York 10036, attention of Syndicate Department (facsimile: (646) 855-3073),
with a copy to ECM Legal (facsimile: (212) 230-8730); notices to the Company shall be directed to it at 550 W. Van Buren Street, Chicago, Illinois 60607, Attention: General Counsel, with a copy to McDermott Will & Emery LLP,
227 W. Monroe Street, Chicago, Illinois 60606, Attention: Eric Orsic (facsimile: (312) 984-7700). 

SECTION 13. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the
Securities pursuant to this Agreement, including the determination of the initial offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and
the several Initial Purchasers, on the other hand, (b) in connection with the offering of the Securities and the process leading thereto, each 

  
 22 

 
Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company, any of its subsidiaries or their respective stockholders, creditors, employees or
any other party, (c) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of the Securities or the process leading thereto (irrespective of whether such
Initial Purchaser has advised or is currently advising the Company or any of its subsidiaries on other matters) and no Initial Purchaser has any obligation to the Company with respect to the offering of the Securities except the obligations
expressly set forth in this Agreement, (d) the Initial Purchasers and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and (e) the Initial Purchasers
have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

 SECTION 14. Parties. This Agreement shall each inure to the benefit of and be binding upon the Initial Purchasers and the Company
and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Initial Purchasers and the Company and their respective successors and the
controlling persons and officers and directors referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.
This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Initial Purchasers and the Company and their respective successors, and said controlling persons and officers and directors and
their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor by reason merely of such purchase. 

SECTION 15. Trial by Jury. The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and
Affiliates) 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. 
 SECTION 16. GOVERNING LAW. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO
THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK. 
 SECTION 17. Consent to
Jurisdiction; Waiver of Immunity. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby shall be instituted in (i) the federal courts of the United States of America
located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party
irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court, as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding.
Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and
unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or
other proceeding brought in any such court has been brought in an inconvenient forum. 
 SECTION 18. TIME. TIME SHALL BE OF THE
ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME. 

  
 23 

 SECTION 19. Counterparts. This Agreement may be executed in any number of counterparts,
each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or any other electronic
transmission shall be effective as delivery of a manually executed counterpart hereof. 
 SECTION 20. Effect of Headings. The Section
headings herein are for convenience only and shall not affect the construction hereof.

 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.

	Concurrent Convertible Note Hedge Transactions and Warrant Transactions:	  	  
 In connection with the pricing of the notes, we entered into one or
more privately negotiated convertible note hedge transactions with Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P Morgan Securities LLC or their respective affiliates (in this capacity, the “hedge counterparties”). The
convertible note hedge transactions collectively cover, subject to customary anti-dilution adjustments, the number of shares of common stock that initially underlie the notes sold in the offering. We also entered into one or more separate, privately
negotiated warrant transactions with the hedge counterparties collectively relating to the same number of shares of our common stock, subject to customary anti-dilution adjustments. The warrants evidenced by the warrant transactions will be settled
on a net-share basis.
  
 The convertible note hedge transactions are intended to reduce
the potential dilution with respect to our common stock and/or offset any potential cash payments we are required to make in excess of the principal amount of converted notes, as the case may be, upon any conversion of the notes. The warrant
transactions could have a dilutive effect with respect to our common stock to the extent that the price per share of our common stock exceeds the strike price of the warrants evidenced by the warrant transactions. The strike price of the warrants
initially equals approximately $97.12 and is subject to customary anti-dilution adjustments.
  

If the initial purchasers exercise their option to purchase additional notes from us, we intend to enter into one or more additional convertible note hedge
transactions and one or more additional warrant transactions with the hedge counterparties, which will initially cover, collectively, the number of shares of our common stock that will initially underlie the additional notes we sell to the initial
purchasers.

			
		
		  	 See “Description of the Concurrent Convertible Note Hedge Transactions and Warrant Transactions” in the Preliminary Offering
Memorandum.

		
	Use of Proceeds:	  	 We estimate that the net proceeds from this offering will be approximately $218.3 million (or approximately $242.6 million if the
initial purchasers fully exercise their option to purchase additional notes), after deducting initial purchasers’ discounts and commissions and estimated expenses payable by us.

 
 We intend to use approximately $16.65 million of the net proceeds of this offering to fund
the cost of entering into the convertible note hedge transactions (after such cost is partially offset by the proceeds that we receive from entering into the warrant transactions). We also intend to use approximately $25 million of the net proceeds
of this offering to repurchase shares of our common stock concurrently with the pricing of this offering from purchasers of the notes.
  

We expect to use the remaining net proceeds from this offering for working capital and general corporate purposes. We may also use the net proceeds for one or
more acquisitions or other strategic transactions. However, we have no current commitments or obligations with respect to any acquisitions or other strategic transactions.
  

If the initial purchasers exercise their option to purchase additional notes, we intend to use a portion of the net proceeds to fund the net cost of entering
into the additional convertible note hedge transactions.

Proceeds” in the Preliminary Offering Memorandum.

 The exact stock prices and effective dates may not be set forth in the table above, in which case: 

 

	 	•	 	if the stock price is between two stock prices listed in the table or the effective date is between two effective dates listed in the table, the number of additional shares will be determined by a straight-line
interpolation between the number of additional shares set forth for the higher and lower stock prices and the earlier and later effective dates based on a 365- or 366-day year, as applicable; 

 

	 	•	 	if the stock price is greater than $300.00 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the
conversion rate; and 

  

	 	•	 	if the stock price is less than $62.66 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the conversion
rate. 

 Notwithstanding the foregoing, in no event will the conversion rate exceed 15.9590 shares per $1,000 principal amount of notes,
subject to adjustment at the same time and in the same manner as the conversion rate as set forth in the Preliminary Offering Memorandum under the caption “Description of Notes—Conversion Rights—Conversion Rate Adjustments.” 

 Our obligation to increase the conversion rate as described above could be considered a penalty, in which case
the enforceability thereof would be subject to general principles of reasonableness and equitable remedies.

 Re: Proposed

 Dear Sirs: 

The undersigned understands that Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) and J.P. Morgan
Securities LLC (“J.P. Morgan”) propose to enter into a Purchase Agreement (the “Purchase Agreement”) with the Company providing for the offering of up to $250,000,000 aggregate principal amount of the Company’s Convertible
Senior Notes (the “Securities”). In recognition of the benefit that such an offering will confer upon the undersigned as a stockholder and an officer and/or director of the Company, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each initial purchaser to be named in the Purchase Agreement that, during the period beginning on the date hereof and ending on the date that is 60 days from the
date of the Purchase Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of Merrill Lynch and J.P. Morgan, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of the Company’s common stock, par value $0.01 per share (the “Common
Stock”), or any securities convertible into or exchangeable or exercisable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition
(collectively, the “Lock-Up Securities”), or exercise any right with respect to the registration of any of the Lock-up Securities, or file or cause to be filed any registration statement in connection therewith, under the Securities Act of
1933, as amended, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or
transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise. 

  
 B-1 

 Notwithstanding the foregoing, the undersigned may transfer the Lock-Up Securities without the
prior written consent of Merrill Lynch and J.P. Morgan in the following circumstances: 
  

	 	(i)	as a bona fide gift or gifts; 

  

	 	(ii)	to any trust, limited liability company, limited partnership or other estate planning vehicle for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this
lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin); 

  

	 	(iii)	as a distribution to limited partners or stockholders of the undersigned; 

  

	 	(iv)	to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned; 

  

	 	(v)	transfers to the Company to satisfy tax withholding obligations that become due during the Lock-Up Period upon vesting of previously issued restricted stock awards or restricted stock units; provided that, if the
undersigned is required to file a report under the Exchange Act reporting a reduction in beneficial ownership of shares of Common Stock during the term of this lock-up agreement related to such disposition of shares of Common Stock to the Company by
the undersigned solely to satisfy tax withholding obligations, the undersigned shall include a statement in such report to the effect that the filing relates to the satisfaction of tax withholding obligations of the undersigned in connection with
the vesting of restricted stock awards or restricted stock units; 

  

	 	(vi)	the sale pursuant to any contract, instruction or plan established prior to the date hereof that satisfies all of the requirements of Rule 10b5-1 (a “10b-5 Plan”) of the Securities Exchange Act of 1934, as
amended (the “Exchange Act”); provided this exception to the lock-up restrictions is referred to in the General Disclosure Package and the Final Offering Memorandum (in each case, as defined in the Purchase Agreement); 

 

	 	(vii)	the establishment of any 10b5-1 Plan, provided that no sales of Lock-Up Securities or securities convertible into, or exchangeable or exercisable for Lock-Up Securities, shall be made pursuant to a 10b5-1 Plan prior to
the expiration of the Lock-Up Period if such 10b5-1 Plan was established after the date hereof; provided, that such 10b5-1 Plan may only be established if no public announcement of the establishment or the existence thereof, and no filing with the
Securities and Exchange Commission or any other regulatory authority shall be required or shall be made voluntarily by the undersigned, the Company or any other person, prior to the expiration of the Lock-Up Period; or 

 

	 	(viii)	the transfer or intestate succession to the legal representatives or a member of the immediate family of the undersigned upon death of the undersigned; 

provided, in the case of clauses (i)-(v), (vii) and (viii) above, that (1) Merrill Lynch and J.P. Morgan receive a signed
lock-up agreement for the balance of the lockup period from each donee, trustee, distributee, or transferee, as the case may be, (2) except as contemplated by clauses (v) and (vi) above, any such transfer shall not involve a
disposition for value, (3) except as contemplated by clauses (v) and (vi) above, such transfers are not required to be reported with the Securities and Exchange Commission on Form 4 in accordance with Section 16 of the Exchange
Act, and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers. 

Furthermore, the undersigned may sell shares of Common Stock of the Company purchased by the undersigned on the open market following the
offering if and only if (i) such sales are not required to be reported in any public report or filing with the Securities Exchange Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or
report regarding such sales. 

  
 B-2 

 The undersigned also agrees and consents to the entry of stop transfer instructions with the
Company’s transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions. 

This Lock-Up Agreement shall lapse and become null and void if (i) the offering shall not have occurred on or before September 30,
2014, (ii) prior to the execution of the Purchase Agreement by the parties thereto, either the Representatives notify the Company, or the Company notifies the Representatives, in writing, that they do not intend to proceed with the offering, or
(iii) the Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder.

	Re:	  	Base Convertible Bond Hedge Transaction
		  	(Transaction Reference Number: 148518079)

 Ladies and Gentlemen: 

The purpose of this communication (this “Confirmation”) is to set forth the terms and conditions of the above-referenced
transaction entered into on the Trade Date specified below (the “Transaction”) between Bank of America, N.A. (“Dealer”) and Huron Consulting Group Inc. (“Counterparty”). This communication
constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below. 
 1. This Confirmation is subject to,
and incorporates, the definitions and provisions of the 2006 ISDA Definitions (including the Annex thereto) (the “2006 Definitions”) and the definitions and provisions of the 2002 ISDA Equity Derivatives Definitions (the
“Equity Definitions”, and together with the 2006 Definitions, the “Definitions”), in each case as published by the International Swaps and Derivatives Association, Inc. (“ISDA”). In the event of any
inconsistency between the 2006 Definitions and the Equity Definitions, the Equity Definitions will govern. Certain defined terms used herein have the meanings assigned to them in the Indenture to be dated as of September 10, 2014 between
Counterparty and U.S. Bank National Association as trustee (the “Indenture”) relating to the USD225,000,000.00 principal amount of 1.25% convertible securities due 2019 (the “Base Convertible Securities”) together
with any 1.25% convertible securities due 2019 that may be issued pursuant to the Initial Purchasers’ option under the Purchase Agreement (as defined below) (the “Optional Convertible Securities” and, together with the Base
Convertible Securities, the “Convertible Securities”). In the event of any inconsistency between the terms defined in the Indenture and this Confirmation, this Confirmation shall govern. For the avoidance of doubt, references herein
to sections of the Indenture are based on the draft of the Indenture most recently reviewed by the parties at the time of execution of this Confirmation. If any relevant sections of the Indenture are changed, added or renumbered following execution
of this Confirmation but prior to the execution of the Indenture, the parties will amend this Confirmation in good faith to preserve the economic intent of the parties based on the draft of the Indenture so reviewed. The parties further acknowledge
that references to the Indenture herein are references to the Indenture as in effect on the date of its execution and if the Indenture is, or the Convertible Securities are, amended, supplemented or modified following their execution, any such
amendment, supplement or modification (other than a Merger Supplemental Indenture (as defined below)) will be disregarded for purposes of this Confirmation (other than (i) as provided in Section 8(a) below and (ii) any amendment,
supplement or modification pursuant to Section 9.01(b) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of the Convertible Securities in the preliminary offering memorandum, as
supplemented by the pricing term sheet related to the Convertible Securities) unless the parties agree otherwise in writing. 

 This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as
to the terms of the Transaction to which this Confirmation relates. This Confirmation shall be subject to an agreement (the “Agreement”) in the form of the 2002 ISDA Master Agreement (the “ISDA Form”) as if Dealer
and Counterparty had executed an agreement in such form (without any Schedule but with the elections set forth in this Confirmation and the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply
to Counterparty with a “Threshold Amount” of USD30.0 million and to Dealer with a “Threshold Amount” of 3% of the stockholders’ equity of Dealer’s ultimate parent company (“Dealer Parent”), in each
case, as if (x) the phrase “, or becoming capable at such time of being declared,” were deleted from Section 5(a)(vi)(1) of the Agreement, (y) the term “Specified Indebtedness” had the meaning specified in
Section 14 of the Agreement, except that such term did not include obligations in respect of deposits received in the ordinary course of a party’s banking business and (z) the following language shall be added to the end of such
Section 5(a)(vi): “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (i) the default was caused solely by error or omission of an administrative or operational
nature; (ii) funds were available to enable the party to make the payment when due; and (iii) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay”. For the avoidance
of doubt, the Transaction shall be the only transaction under the Agreement. 
 All provisions contained in, or incorporated by reference
to, the Agreement will govern this Confirmation except as expressly modified herein. In the event of any inconsistency between this Confirmation and either the Definitions or the Agreement, this Confirmation shall govern. For the avoidance of doubt,
except to the extent of an express conflict, the application of any provision of this Confirmation, the Agreement or the Equity Definitions shall not be construed to exclude or limit the application of any other provision of this Confirmation, the
Agreement or the Equity Definitions.

	 Notice of Exercise:
	  	Notwithstanding anything to the contrary in the Equity Definitions, Dealer shall have no obligation to make any payment or delivery in respect of any exercise of Options hereunder unless Counterparty notifies Dealer in writing prior

scheduled settlement date under the Indenture for the Convertible Securities converted on the Conversion Date corresponding to such Exercise Date, (iii) whether such Relevant Convertible Securities will be settled by Counterparty by delivery of

 3 

			
		  	“Observation Period” (as defined in the Indenture); provided that in the case of any exercise of Options hereunder in connection with the conversion of any Relevant Convertible Securities on any Conversion Date occurring

Act (as defined below) and the rules and regulations thereunder, in respect of any election of a settlement method with respect to the Convertible Securities. For the avoidance of doubt, if Counterparty fails to give such notice when due in respect
of any exercise of Options hereunder, Dealer’s obligation to make any payment or delivery in respect of such exercise shall be permanently extinguished, and late notice shall not cure such failure; provided that notwithstanding the
foregoing, such notice (and the related exercise of Options) in connection with any conversion of Relevant Convertible Securities prior to the Final Conversion Period (or, if earlier, the second “Scheduled Trading Day” (as defined in the
Indenture) prior to the first “VWAP Trading Day” (as defined in the Indenture) of the “Observation Period” that applies to the Convertible Security Settlement Method) shall be effective if given after the Exercise Notice
Deadline, but prior to 4:00 PM New York City time, on the fifth Exchange Business Day following the Exercise Notice Deadline, in which event the Calculation Agent shall have the right to adjust the Delivery Obligation as appropriate to reflect the
additional costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities (including the unwinding of any hedge position) as a result of Dealer not having
received such notice on or prior to the Exercise Notice Deadline.
	 Notice of Convertible Security
	  	
	 Settlement Method:
	  	Counterparty shall notify Dealer in writing by 5:00 P.M. (New York City time) on the 105th “Scheduled Trading Day” preceding the “Maturity Date” (each as defined in the Indenture) of the irrevocable election

Conversion Date occurring on or after the 105th “Scheduled Trading Day” preceding the “Maturity Date” and ending on and including the second “Scheduled Trading Day”
immediately preceding the “Maturity Date” (each as defined in the Indenture) (the “Free Convertibility Period”). If Counterparty fails timely to provide such notice, Counterparty shall be deemed to have notified Dealer of
combination settlement with a “Specified Dollar Amount” (as defined in the Indenture) of USD1,000 for all conversions occurring during the Free Convertibility Period. Counterparty agrees that it shall settle any Relevant Convertible
Securities with a Conversion Date occurring during the Free Convertibility Period in the same manner as provided in the Notice of Convertible Security Settlement Method it provides or is deemed to have provided
hereunder.

	 Delivery Obligation:
	  	In lieu of the obligations set forth in Sections 8.1 and 9.1 of the Equity Definitions, and subject to “Notice of Exercise” above, in respect of an Exercise Date occurring on a Conversion Date, Dealer will deliver to
Counterparty, on the related Settlement Date, a number of Shares and/or amount of cash in USD equal to the product of (i) the Applicable Percentage and (ii) (x) the aggregate number of Shares, if any, that Counterparty would be obligated to deliver
to the holder(s) of the Relevant Convertible Securities converted on such Conversion Date pursuant to Section 10.03(b) of the Indenture and/or (y) the aggregate amount of cash, if any, in excess of USD1,000 per Convertible Security (in denominations
of USD1,000) that Counterparty would be obligated to deliver to holder(s) pursuant to Section 10.03(b) of the Indenture, as determined by the Calculation Agent by reference to such Section of the Indenture (except that such aggregate number of
Shares shall be determined without taking into consideration any rounding pursuant to Section 10.03(b) of the Indenture and shall be rounded down to the nearest whole number) and cash in lieu of fractional Shares, if any, resulting from such
rounding, if Counterparty had elected to satisfy its conversion obligation in respect of such Relevant Convertible Securities by the Convertible Security Settlement Method, notwithstanding any different actual election by Counterparty with respect
to the settlement of such Convertible Securities ( the “Convertible Obligation”); provided that such obligation shall be determined (i) excluding any Shares and/or cash that Counterparty is obligated to deliver to holder(s)
of the Relevant Convertible Securities as a result of any adjustments to the Conversion Rate pursuant to Sections 10.05(g), 10.05(j), or 10.07 of the Indenture and (ii) without regard to the election, if any, by Counterparty to adjust the Conversion
Rate (and, for the avoidance of doubt, the Delivery Obligation shall not include any interest payment on the Relevant Convertible Securities that the Counterparty is (or would have been) obligated to deliver to holder(s) of the Relevant Convertible
Securities for such Conversion Date); and provided further that if such exercise relates

  
 5 

			
		
		  	to the conversion of Relevant Convertible Securities in connection with which holders thereof are entitled to receive additional Shares and/or cash pursuant to the adjustment to the Conversion Rate set forth in Section 10.07 of the
Indenture, then, notwithstanding the foregoing, the Delivery Obligation shall include the Applicable Percentage of such additional Shares and/or cash (as determined by the Calculation Agent by reference to such Section of the Indenture), except that
the Delivery Obligation shall be capped so that the value of the Delivery Obligation per Option (with the value of any Shares included in the Delivery Obligation determined by the Calculation Agent using the VWAP Price (as defined below) on the last
day of the relevant “Observation Period”, as defined in the Indenture (as modified by the provision set forth opposite the caption “Convertible Security Settlement Method”)) does not exceed the amount as determined by the
Calculation Agent that would be payable by Dealer pursuant to Section 6 of the Agreement if such Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction (except that, for
purposes of determining such amount (x) the Number of Options shall be deemed to be equal to the number of Options exercised on such Exercise Date and (y) such amount payable will be determined as if Section 10.07 of the Indenture were deleted) was
the sole Affected Transaction and Counterparty was the sole Affected Party (determined without regard to Section 8(b) of this Confirmation). Notwithstanding the foregoing, and in addition to the cap described in the further proviso to the preceding
sentence, in all events the Delivery Obligation shall be capped so that the value of the Delivery Obligation does not exceed the value of the Convertible Obligation (with the Convertible Obligation determined based on the actual settlement method
elected by Counterparty with respect to such Relevant Convertible Securities instead of the Convertible Security Settlement Method and with the value of any Shares included in either the Delivery Obligation or such Convertible Obligation determined
by the Calculation Agent using the VWAP Price on the last day of the relevant “Observation Period” (as modified by the provision set forth opposite the caption “Convertible Security Settlement Method”)).
		
	Convertible Security Settlement Method:	  	For any Relevant Convertible Securities, if Counterparty has notified Dealer in the related Notice of Exercise (or in the Notice of Convertible Security Settlement Method, as the case may be) that it has elected to satisfy its
conversion obligation in respect of such Relevant Convertible Securities in cash or in a combination of cash and Shares in accordance with Section 10.03(a) of the Indenture (a “Cash Election”) with a “Specified Dollar
Amount” (as defined in the Indenture) of at least USD1,000, the Convertible Security Settlement Method shall be the settlement method actually so elected by Counterparty in respect of such Relevant Convertible Securities; otherwise, (i) the
Convertible Security Settlement Method shall assume Counterparty made a Cash Election with respect to such Relevant Convertible Securities with a “Specified Dollar Amount” (as defined in the Indenture) of USD1,000 per Relevant Convertible
Security and (ii) the Delivery Obligation shall be calculated as if the relevant “Observation Period” (as defined in the Indenture) pursuant to Section

  
 6 

			
		
		  	10.03(b)(iii) of the Indenture consisted of 100 “VWAP Trading Days” (as defined in the Indenture) commencing on (x) the second “Scheduled Trading Day” (as defined in the Indenture) after the Conversion Date for
conversions occurring prior to the 105th “Scheduled Trading Day” preceding the “Maturity Date” (each as defined in the Indenture) or (y) the 102nd “Scheduled Trading Day” prior to the “Maturity Date” (each as defined in the Indenture) for conversions occurring on or after the
105th “Scheduled Trading Day” preceding the “Maturity Date” (each as defined in the Indenture).
		
	 Notice of Delivery Obligation:
	  	No later than the “Scheduled Trading Day” (as defined in the Indenture) immediately following the last day of the relevant “Observation Period”, as defined in the Indenture (as modified by the provision set forth
opposite the caption “Convertible Security Settlement Method”), Counterparty shall give Dealer notice of the final number of Shares and/or cash comprising the Convertible Obligation (determined as though the words “the Applicable
Percentage” in clause (i) of the definition thereof were deleted and replaced with the word “one”); provided that, with respect to any Exercise Date occurring during the Final Conversion Period, Counterparty may provide Dealer
with a single notice of an aggregate number of Shares and/or cash comprising the Convertible Obligations (determined as though the words “the Applicable Percentage” in clause (i) of the definition thereof were deleted and replaced with the
word “one”) for all Exercise Dates occurring in such period (it being understood, for the avoidance of doubt, that the requirement of Counterparty to deliver such notice shall not limit Counterparty’s obligations with respect to
Notice of Exercise or Notice of Convertible Security Settlement Method or Dealer’s obligations with respect to Delivery Obligation, each as set forth above, in any way).
		
	 Other Applicable Provisions:
	  	To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 1.27, 9.1(c), 9.8, 9.9 and 9.11 (except that the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall
be modified by excluding any representations therein relating to restrictions, obligations, limitations or requirements under applicable securities laws arising as a result of the fact that Counterparty is the Issuer of the Shares) of the Equity
Definitions will be applicable as if “Physical Settlement” applied to the Transaction.
		
	 Restricted Certificated Shares:
	  	Notwithstanding anything to the contrary in the Equity Definitions, Dealer may, in whole or in part, deliver Shares required to be delivered to Counterparty hereunder in certificated form in lieu of delivery through the Clearance
System. With respect to such certificated Shares, the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by deleting the remainder of the provision after the word “encumbrance” in the fourth
line thereof.

 Share Adjustments: 
  

			
	 Method of Adjustment:
	  	Notwithstanding Section 11.2 of the Equity Definitions, upon the occurrence of any event or condition set forth in Sections 10.05(a) through (e) of the Indenture that the Calculation Agent determines would result in an adjustment
under the Indenture by reference to

  
 7 

			
		
		  	such Sections thereof (any such event or condition, an “Adjustment Event”), the Calculation Agent shall make a corresponding adjustment to the terms relevant to the exercise, settlement or payment of the
Transaction, subject to “Discretionary Adjustments” below. Promptly following the occurrence of any Adjustment Event, Counterparty shall notify the Calculation Agent of such Adjustment Event; and once the adjustments to be made to the
terms of the Indenture and the Convertible Securities in respect of such Adjustment Event have been determined, Counterparty shall promptly notify the Calculation Agent in writing of the details of such adjustments.
		
		  	In addition, the Calculation Agent shall, to the extent the Calculation Agent determines practicable in good faith and in its commercially reasonable discretion (taking into account the Convertible Security Settlement Method and
Dealer’s Hedge Positions), make a corresponding adjustment to the terms relevant to the exercise, settlement or payment of the Transaction (but without duplication of any adjustment pursuant to the foregoing sentence) upon the occurrence of any
event or condition that the Calculation Agent determines (taking into account the Convertible Security Settlement Method and Dealer’s Hedge Positions) would result in an adjustment under the Indenture by reference to Sections 10.05(f), 10.05(g)
or 10.05(h) of the Indenture; provided that the Calculation Agent may limit or alter any such adjustment referenced in this sentence so that the fair value of the Transaction to Dealer is not reduced as a result of such adjustment.
		
		  	For the avoidance of doubt, Dealer shall not have any payment or delivery obligation hereunder in respect of, and no adjustment shall be made to the terms of the Transaction on account of, (x) any distribution of cash, property or
securities by Counterparty to the holders of Convertible Securities (upon conversion or otherwise) or (y) any other transaction in which holders of Convertible Securities are entitled to participate, in each case, in lieu of an adjustment under the
Indenture in respect of an Adjustment Event (including, without limitation, under the second paragraph Section 10.05(c)(i) of the Indenture or the third paragraph of Section 10.05(d) of the Indenture).
		
	 Discretionary Adjustments:
	  	Notwithstanding anything to the contrary herein or in the Equity Definitions, if the Calculation Agent in good faith disagrees with any adjustment under the Indenture that involves an exercise of discretion by Counterparty or its
board of directors (including, without limitation, pursuant to Section 10.05(h) of the Indenture, pursuant to Section 10.06 of the Indenture or any supplemental indenture entered into thereunder (a “Merger Supplemental
Indenture”) or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then the Calculation Agent will determine the adjustment to be made to any one
or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment of or under the Transaction in a commercially reasonable manner. 

  
 8 

 Extraordinary Events: 
  

			
	 Merger Events:
	  	Notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any “Conversion Right Change Event” (as defined in the Indenture).
		
	 Consequences of Merger Events:
	  	Notwithstanding Sections 12.2 and 12.3 of the Equity Definitions, upon the occurrence of a Merger Event that the Calculation Agent determines by reference to Section 10.06 of the Indenture would result in an adjustment under the
Indenture, the Calculation Agent shall make a corresponding adjustment to the terms relevant to the exercise, settlement or payment of the Transaction, subject to “Discretionary Adjustments” above; provided that such adjustment
shall be made without regard to any adjustment to the Conversion Rate pursuant to Section 10.05(j) or 10.07 of the Indenture and the election, if any, by Counterparty to adjust the Conversion Rate; and provided further that the Calculation
Agent may limit or alter any such adjustment referenced in this paragraph so that the fair value of the Transaction to Dealer (taking into account a commercially reasonable hedge position) is not adversely affected as a result of such adjustment;
and provided further that if, with respect to a Merger Event, (i) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation organized under the
laws of the United States, any State thereof or the District of Columbia or (ii) the Counterparty following such Merger Event will not be a corporation organized under the laws of the United States, any State thereof or the District of Columbia or
will not be the Issuer following such Merger Event, in either case, Dealer may elect in its commercially reasonable discretion that Cancellation and Payment (Calculation Agent Determination) shall apply.
		
	 Notice of Merger Consideration:
	  	Upon the occurrence of a Merger Event that causes the Shares to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), Counterparty shall
reasonably promptly (but, in any event prior to the effective time of such Merger Event) notify the Calculation Agent of (i) the weighted average of the types and amounts of consideration received by the holders of Shares entitled to receive cash,
securities or other property or assets with respect to or in exchange for such Shares in any Merger Event who affirmatively make such an election or, if no holders of Shares affirmatively make such an election, the types and amounts of consideration
actually received by holders of Shares and (ii) the details of the adjustment made under the Indenture in respect of such Merger Event.
		
	 Nationalization, Insolvency or Delisting:
	  	Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it shall also constitute a Delisting if the Shares are not
immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any
such exchange or quotation system, such exchange or quotation system shall thereafter be deemed to be the Exchange.

not aware of any material nonpublic information regarding Counterparty or the Shares and (B) all reports and other documents filed by Counterparty with the Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934, as
amended (the “Exchange Act”) when considered as a whole (with the more recent such reports and documents deemed to amend inconsistent statements contained in any earlier such reports and documents), do not contain any untrue
statement of a material fact or any omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading. 

(ii) (A) On the Trade Date, the Shares or securities that are convertible into, or exchangeable or exercisable for Shares, are
not, and shall not be, subject to a “restricted period,” as such term is defined in Regulation M under the Exchange Act (“Regulation M”) and (B) Counterparty shall not engage in any “distribution,” as such
term is defined in Regulation M, other than a distribution meeting the requirements of the exceptions set forth in sections 101(b)(10) and 102(b)(7) of Regulation M, until the second Exchange Business Day immediately following the Trade Date. 

(iii) On the Trade Date, neither Counterparty nor any “affiliate” or “affiliated purchaser” (each as
defined in Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall directly or indirectly (including, without limitation, by means of any cash-settled or other derivative instrument) purchase, offer to purchase, place any bid or
limit order that would effect a purchase of, or commence any tender offer relating to, any Shares (or an equivalent interest, including a unit of beneficial interest in a trust or limited partnership or a depository share) or any security
convertible into or exchangeable or exercisable for Shares, except through Dealer. 
 (iv) Without limiting the generality of
Section 13.1 of the Equity Definitions, Counterparty acknowledges that Dealer is not making any representations or warranties or taking any position or expressing any view with respect to the treatment of the Transaction under any accounting
standards including ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, or ASC Topic 480, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging – Contracts in Entity’s

(vi) On or prior to the Trade Date, Counterparty shall deliver to Dealer a resolution of Counterparty’s board of directors
or any duly authorized committee thereof authorizing the Transaction and such other certificate or certificates as Dealer shall reasonably request. 

(vii) Counterparty is not entering into this Confirmation to create actual or apparent trading activity in the Shares (or any

the jurisdiction of its incorporation.

(including non-U.S. jurisdictions) law, rule, regulation or regulatory order applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval
from any person or entity) as a result of Dealer or its affiliates owning or holding (however defined) Shares. 
 (xi) The
representations and warranties of Counterparty set forth in Section 3 of the Agreement and Section 1 of the Purchase Agreement dated as of September 4, 2014, among the Counterparty and Merrill Lynch, Pierce, Fenner & Smith

 (xv)
Counterparty understands, acknowledges and agrees that: (A) at any time during the term of the Transaction, Dealer and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or
other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be active in the market for Shares other than in connection with hedging activities in relation to the

well as the relevant prices with respect to the shares referred to herein, each in a manner that may be adverse to Counterparty. 
 (b) Each
of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” as defined in Section 1a(18) of the U.S. Commodity Exchange Act, as amended. 

(c) Each of Dealer and Counterparty acknowledges that the offer and sale of the Transaction to it is intended to be exempt from registration

economic risk of its investment in the Transaction and is able to bear a total loss of its investment, (ii) it is an “accredited investor” as that term is defined in Regulation D as promulgated under the Securities Act, (iii) it

 13 

 
entering into the Transaction for its own account and without a view to the distribution or resale thereof and (iv) the assignment, transfer or other disposition of the Transaction has not

(d) Counterparty agrees and acknowledges that Dealer is a “financial institution” and “financial participant” within the
meaning of Sections 101(22) and 101(22A) of the Bankruptcy Code. The parties hereto further agree and acknowledge that it is the intent of the parties that (A) this Confirmation is a “securities contract,” as such term is defined in
Section 741(7) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment amount” or “other transfer obligation” within the
meaning of Section 362 of the Bankruptcy Code and a “settlement payment,” within the meaning of Section 546 of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a
“termination value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “transfer,” as such term is defined in Section 101(54) of the
Bankruptcy Code and a “payment or other transfer of property” within the meaning of Sections 362 and 546 of the Bankruptcy Code, and (B) Dealer is entitled to the protections afforded by, among other sections, Sections 362(b)(6),
362(b)(27), 362(o), 546(e), 546(j), 548(d)(2), 555 and 561 of the Bankruptcy Code. 
 (e) Counterparty shall deliver to Dealer an opinion of
counsel, dated as of the Effective Date and reasonably acceptable to Dealer in form and substance, with respect to the matters set forth in Section 3(a) of the Agreement, Sections 7(a)(viii) and 7(a)(xiv) hereof and such other matters as Dealer
may reasonably request, subject to such qualifications and assumptions that are customary for legal opinions of this type. 
 8. Other
Provisions: 
 (a) Additional Termination Events. The occurrence of (i) an “Event of Default” with respect to
Counterparty under the terms of the Convertible Securities as set forth in Section 6.01(a) of the Indenture or (ii) an Amendment Event shall be an Additional Termination Event with respect to which the Transaction is the sole Affected
Transaction and Counterparty is the sole Affected Party and Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. 

“Amendment Event” means that Counterparty amends, modifies, supplements, waives or obtains a waiver in respect
of any term of the Indenture or the Convertible Securities governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, redemption right of Counterparty, any term relating to conversion of the Convertible Securities
(including changes to the conversion rate, conversion rate adjustment provisions, conversion settlement dates or conversion conditions), or any term that would require consent of the holders of not less than 100% of the principal amount of the
Convertible Securities to amend (other than Sections 9.02(b) or 9.02(g) of the Indenture), in each case without the consent of Dealer, which consent shall not be unreasonably withheld, conditioned or delayed. 

(b) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If Dealer shall owe Counterparty any
amount pursuant to “Consequences of Merger Events” above or Sections 12.6, 12.7 or 12.9 of the Equity Definitions or pursuant to Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Counterparty shall have the
right, in its sole discretion, to require Dealer to satisfy any such Payment Obligation by the Share Termination Alternative (as defined below) by giving irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day,
no later than 9:30 A.M. New York City time on the relevant merger date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable (“Notice of Share
Termination”); provided that if Counterparty does not elect to require Dealer to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its sole discretion, to elect to satisfy its
Payment Obligation by the Share Termination Alternative, notwithstanding Counterparty’s failure to elect or election to the contrary; and provided further that Counterparty shall not have the right to so elect (but, for the avoidance of
doubt, Dealer shall have the right to so elect) in the event (i) of an Insolvency, a Nationalization or a Merger Event, in each case, in which the consideration or proceeds to be paid to holders of Shares consists solely of cash, (ii) of
an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party or an Extraordinary Event, which Event of Default, Termination Event or Extraordinary Event resulted from an event
or events within Counterparty’s control or (iii) that Counterparty fails to remake the representation set forth in Section 7(a)(i) as of the date of such election. Upon such Notice of Share Termination, the following provisions shall
apply on the Scheduled Trading Day immediately following the relevant merger date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable:

	Share Termination Alternative:	  	If applicable, means that Dealer shall deliver to Counterparty the Share Termination Delivery Property on the date on which the Payment Obligation would otherwise be due pursuant to “Consequences of Merger Events” above,
Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, or such later date or dates as the Calculation Agent may reasonably determine (the “Share Termination Payment Date”), in
satisfaction of the Payment Obligation.
		
	Share Termination Delivery	  	
	Property:	  	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery
Property by replacing any fractional portion of the aggregate amount of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.
		
	Share Termination Unit Price:	  	The value of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its
discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation.
		
	Share Termination Delivery Unit:	  	In the case of a Termination Event, Event of Default, Delisting or Additional Disruption Event, one Share or, in the case of an Insolvency, Nationalization or Merger Event, one Share or a unit consisting of the number or 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 or Merger Event, as applicable.
If such Insolvency, Nationalization or Merger Event involves a choice of consideration to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.
		
	Failure to Deliver:	  	Applicable
		
	Other applicable provisions:	  	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (except that the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by excluding any
representations therein relating to restrictions, obligations, limitations or requirements under applicable securities laws arising as a result of the fact that Counterparty is the issuer of the Shares or any portion of the Share Termination
Delivery Units) of the Equity Definitions will be applicable as if “Physical Settlement” applied to the Transaction, except that all references to “Shares” shall be read as references to “Share Termination Delivery
Units.”

 (c) Disposition of Hedge Shares. Counterparty hereby agrees that if, in the good faith reasonable
judgment of Dealer based on advice of counsel, any Shares (the “Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without
registration under the Securities Act, Counterparty shall, at its election: (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act to
cover the resale of such Hedge Shares and (A) enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered offering of similar size, (B) provide
accountant’s “comfort” letters in customary form for registered offerings of equity securities of similar size, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to
Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities and (E) afford Dealer a reasonable opportunity to conduct a “due diligence”
investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities of similar size; provided, however, that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence
materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of this Section 8(c) shall apply at the election of
Counterparty; (ii) in order to allow Dealer to sell the Hedge Shares 

  
 15 

 
in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities of similar
size, in form and substance reasonably satisfactory to Dealer, including customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated
buyer of the Hedge Shares from Dealer), opinions and certificates and such other documentation as is customary for private placements of similar size, all reasonably acceptable to Dealer (in which case, the Calculation Agent shall make any
adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement); or
(iii) purchase the Hedge Shares from Dealer at the VWAP Price on such Exchange Business Days, and in the amounts, requested by Dealer. “VWAP Price” means, on any Exchange Business Day, the per Share volume-weighted average
price as displayed under the heading “Bloomberg VWAP” on Bloomberg Screen HURN <Equity> VAP (or any successor thereto) in respect of the period from 9:30 a.m. to 4:00 p.m. (New York City time) on such Exchange Business Day (or if
such volume-weighted average price is unavailable or is manifestly incorrect, the market value of one Share on such Exchange Business Day, as determined by the Calculation Agent using a volume-weighted method). 

(d) Amendment to Equity Definitions. The following amendment shall be made to the Equity Definitions: 

Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word
“or” after the word “official” and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) at Dealer’s option,
the occurrence of any of the events specified in Section 5(a)(vii) (1) through (9) of the ISDA Master Agreement with respect to that Issuer.” 

(e) Repurchase and Conversion Rate Adjustment Notices. Counterparty shall, at least 10 Scheduled Trading Days prior to effecting any
repurchase of Shares or consummating or otherwise executing or engaging in any transaction or event (a “Conversion Rate Adjustment Event”) that would lead to an increase in the Conversion Rate (as such term is defined in the
Indenture), give Dealer a written notice of such repurchase or Conversion Rate Adjustment Event (a “Repurchase Notice”) if, following such repurchase or Conversion Rate Adjustment Event, the Notice Percentage as determined on the
date of such Repurchase Notice is (i) greater than 4.5% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than the
Notice Percentage as of the date hereof), and, if such repurchase or Conversion Rate Adjustment Event, or the intention to effect the same, would constitute material non-public information with respect to Counterparty or the Shares, Counterparty
shall make public disclosure thereof at or prior to delivery of such Repurchase Notice. The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of which is the Number of Shares plus the number
of Shares underlying any other call options sold by Dealer to Counterparty and the denominator of which is the number of Shares outstanding on such day. In the event that Counterparty fails to provide Dealer with a Repurchase Notice on the day and
in the manner specified in this Section 8(e) then Counterparty agrees to indemnify and hold harmless Dealer, its affiliates and their respective directors, officers, employees, agents and controlling persons (Dealer and each such person being
an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable securities laws,
including without limitation, Section 16 of the Exchange Act, relating to or arising out of such failure. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified
Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability. In addition, Counterparty will reimburse any Indemnified
Party for all expenses (including reasonable counsel fees and expenses) as they are incurred (after notice to Counterparty) in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any
action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. This indemnity shall survive
the completion of the Transaction contemplated by this Confirmation and any assignment and delegation of the Transaction made pursuant to this Confirmation or the Agreement shall inure to the benefit of any permitted assignee of Dealer. 

(f) Transfer and Assignment. Either party may transfer any of its rights or obligations under the Transaction with the prior written
consent of the non-transferring party, such consent not to be unreasonably withheld or delayed. For the avoidance of doubt, Dealer may condition its consent on any of the following, without limitation: (i) the receipt by Dealer of opinions and
documents reasonably satisfactory to Dealer in connection with such assignment, (ii) such assignment being effected on terms reasonably satisfactory to Dealer with respect to any legal and regulatory requirements relevant to Dealer,
(iii) Counterparty continuing to be obligated to provide notices hereunder relating to the 

  
 16 

 
Convertible Securities and continuing to be obligated with respect to “Disposition of Hedge Shares” and “Repurchase and Conversion Rate Adjustment Notices” above,
(iv) payment by Counterparty of all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such assignment, (v) Dealer not being obliged, as a result of such assignment, to pay the assignee
on any payment date, an amount greater than Dealer would have been required to pay in the absence of such assignment, (vi) no Event of Default, Potential Event of Default or Termination Event occurring as a result of such assignment and
(vii) Counterparty causing the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that the results described in clauses (v) and
(vi) will not occur upon or after such transfer. In addition, Dealer may transfer or assign without any consent of the Counterparty its rights and obligations hereunder and under the Agreement, in whole or in part, to any of its affiliates
(i) with a credit quality equivalent to Dealer or Dealer’s guarantor or (ii) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer or its relevant affiliate for similar
transactions, by Dealer, an affiliate of Dealer with credit quality equivalent to Dealer or Dealer Parent or Dealer’s guarantor, in each case, only if (x) an Event of Default, Potential Event of Default or Termination Event will not occur
as a result of such transfer or assignment, (y) as a result of such transfer or assignment, Counterparty will not be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement, as applicable,
greater than the amount that Counterparty would have been required to pay to Dealer in the absence of such transfer or assignment and (z) such transfer or assignment is made to a transferee or assignee that is a “dealer in securities”
within the meaning of Section 475(c)(1) of the Code. At any time at which any Excess Ownership Position or a Hedging Disruption exists, if Dealer, in its discretion, is unable to effect a transfer or assignment to a third party in accordance
with the requirements set forth above after using its commercially reasonable efforts on pricing terms and within a time period reasonably acceptable to Dealer such that an Excess Ownership Position or a Hedging Disruption, as the case may be, no
longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of the Transaction, such that such Excess Ownership Position or Hedging Disruption, as
the case may be, no longer exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment or delivery shall be made pursuant to Section 6 of the Agreement and Section 8(b)
of this Confirmation as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Terminated Portion of the Transaction, (ii) Counterparty shall be the sole Affected Party with respect
to such partial termination and (iii) such portion of the Transaction shall be the only Terminated Transaction. “Excess Ownership Position” means any of the following: (i) the Equity Percentage exceeds 7.5%, (ii) the
Option Equity Percentage exceeds 14.5%, (iii) Dealer or any “affiliate” or “associate” of Dealer would own in excess of 13% of the outstanding Shares for purposes of Section 203 of the Delaware General Corporation Law
or (iii) Dealer, Dealer Group (as defined below) or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a “Dealer Person”) under any federal,
state or local laws, regulations, regulatory orders or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns,
constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership in excess of a number of Shares equal to (x) the number of Shares that would give rise to reporting or registration obligations or
other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under Applicable Restrictions, as determined by Dealer in its reasonable discretion,
and with respect to which such requirements have not been met or the relevant approval has not been received or that would give rise to any consequences under the constitutive documents of Counterparty or any contract or agreement to which
Counterparty is a party, in each case minus (y) 1% of the number of Shares outstanding on the date of determination. The “Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the
numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation with Dealer, for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any
“group” (within the meaning of Section 13) of which Dealer is or may be deemed to be a part (Dealer and any such affiliates, persons and groups, collectively, “Dealer Group”) beneficially owns (within the meaning of
Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that, as a result of a change in law, regulation or interpretation after the date hereof, the equivalent calculation under Section 16 of the Exchange Act
and the rules and regulations thereunder results in a higher number, such number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Option Equity Percentage” as of any day is the fraction,
expressed as a percentage, (A) the numerator of which is the sum of (1) the Number of Shares and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the
denominator of which is the number of Shares outstanding. 

  
 17 

 (g) Staggered Settlement. If upon advice of counsel with regard to applicable legal and
regulatory requirements Dealer reasonably determines that it would not be advisable to deliver, or to acquire Shares to deliver, any or all of the shares to be delivered by Dealer on the relevant “Nominal Settlement Date”, Dealer may, by
notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal
Settlement Date as follows: 
 (i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates
(each of which will be on or prior to such Nominal Settlement Date, but not prior to the beginning of the related “Observation Period”, as defined in the Indenture (as modified by the provision set forth opposite the caption
“Convertible Security Settlement Method”)) or delivery times and how it will allocate the Shares it is required to deliver under “Delivery Obligation” (above) among the Staggered Settlement Dates or delivery times; and 

(ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates
and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date. 
 (h)
Right to Extend. Dealer, acting commercially reasonably, may postpone or add, in whole or in part, any Exercise Date or Settlement Date or any other date of valuation or delivery by Dealer, with respect to some or all of the relevant Options
(in which event the Calculation Agent shall make appropriate adjustments to the Delivery Obligation), if Dealer determines, based on advice of counsel in the case of the immediately following clause (ii), that such extension or addition by Dealer is
reasonably necessary or appropriate (i) to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions in the cash market, the stock loan market or any other relevant
market or (ii) to enable Dealer to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in
compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted
by Dealer in good faith in relation to such requirements). 
 (i) Adjustments. For the avoidance of doubt, whenever the Calculation
Agent is called upon to make an adjustment pursuant to the terms of this Confirmation or the Definitions to take into account the effect of an event, the Calculation Agent shall make such adjustment by reference to the effect of such event on the
Hedging Party, assuming that the Hedging Party maintains a commercially reasonable hedge position. 
 (j) Disclosure. Effective from
the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of
the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax structure. 

(k) Designation by Dealer. Notwithstanding any other provision in this Confirmation 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 the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance in conformance with this Agreement; provided that Dealer
shall not be relieved hereby of any liability relating to the manner of such performance or any failure to perform. 
 (l) No Netting and
Set-off. Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable law or
otherwise. 
 (m) Equity Rights. Dealer acknowledges and agrees that this Confirmation is not intended to convey to it rights with
respect to the Transaction that are senior to the claims of common stockholders in the event of Counterparty’s bankruptcy. For the avoidance of doubt, the parties agree that the preceding sentence shall not apply at any time other than during
Counterparty’s bankruptcy to any claim arising as a result of a breach by Counterparty of any of its obligations under this Confirmation or the Agreement. For the avoidance of doubt, the parties acknowledge that this Confirmation is not secured
by any collateral that would otherwise secure the obligations of Counterparty herein under or pursuant to any other agreement. 
 (n)
Early Unwind. In the event the sale by Counterparty of the Initial Securities (as defined in the Purchase Agreement) is not consummated with the initial purchasers pursuant to the Purchase Agreement for any reason by the close of business in
New York on September 10, 2014 (or such later date as agreed upon by the parties, which in 

  
 18 

 
no event shall be later than September 24, 2014) (September 10, 2014 or such later date being the “Early Unwind Date”), the Transaction shall automatically terminate
(the “Early Unwind”), on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Counterparty thereunder shall be cancelled and terminated and (ii) only in the case
where such Early Unwind occurred as a result of events within Counterparty’s control, Counterparty shall (x) pay to Dealer an amount in cash equal to the aggregate amount of costs and expenses relating to the unwinding of Dealer’s
hedging activities in respect of the Transaction (including market losses incurred in reselling any Shares purchased by Dealer or its affiliates in connection with such hedging activities) or (y) at the election of Counterparty, deliver to
Dealer Shares with a value equal to such amount, as commercially reasonably determined by the Calculation Agent, in which event the parties shall enter into customary and commercially reasonable documentation relating to the registered or exempt
resale of such Shares; provided that, if Counterparty makes such election to deliver Shares, notwithstanding the foregoing, the number of Shares so delivered will not exceed a number of Shares equal to two multiplied by the Number of
Shares (with such Number of Shares determined, for the avoidance of doubt, as if the relevant Convertible Securities had been issued). Following such termination, cancellation and payment, each party shall be released and discharged by the other
party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of either party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date.
Dealer and Counterparty represent and acknowledge to the other that upon an Early Unwind and following the payment referred to above, all obligations with respect to the Transaction shall be deemed fully and finally discharged. 

(o) Wall Street Transparency and Accountability Act of 2010. The parties hereby agree that none of (v) Section 739 of the Wall
Street Transparency and Accountability Act of 2010 (“WSTAA”), (w) any similar legal certainty provision in any legislation enacted, or rule or regulation promulgated, on or after the Trade Date, (x) the enactment of WSTAA
or any regulation under the WSTAA, (y) any requirement under WSTAA nor (z) an amendment made by WSTAA, shall limit or otherwise impair either party’s rights to terminate, renegotiate, modify, amend or supplement this Confirmation or
the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not
limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position or Illegality (as defined in the Agreement)). 

(p) Tax Matters  

(i) Withholding Tax imposed on payments to non-US counterparties under the United States Foreign Account Tax Compliance
Act. “Tax” and “Indemnifiable Tax”, each as defined in Section 14 of the Agreement, shall not include any U.S. federal withholding tax imposed or collected pursuant to Sections 1471 through 1474 of the U.S. Internal
Revenue Code of 1986, as amended (the “Code”), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation,
rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (a “FATCA Withholding Tax”). For the avoidance of doubt, a FATCA Withholding Tax
is a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement. 

(ii) HIRE Act. “Tax” and “Indemnifiable Tax”, each as defined in Section 14 of the
Agreement, shall not include any tax imposed on payments treated as dividends from sources within the United States under Section 871(m) of the Code or any regulations issued thereunder. 

(iii) Tax documentation. Counterparty shall provide to Dealer a valid U.S. Internal Revenue Service Form W-9, or any
successor thereto, (i) on or before the date of execution of this Confirmation and (ii) promptly upon learning that any such tax form previously provided by Counterparty has become obsolete or incorrect. Additionally, Counterparty shall,
promptly upon request by Dealer, provide such other tax forms and documents requested by Dealer. Dealer shall provide Counterparty, as applicable, (x) a valid U.S. Internal Revenue Service Form W-9 or W-8ECI or (y) (A) a valid
Internal Revenue Service Form W-8IMY along with a withholding statement and (B) attached a valid Internal Revenue Service Form W-9 or Internal Revenue Service Form W-8ECI, or, in each case, any successor thereto, (i) on or before the date
of execution of this Confirmation and (ii) promptly upon learning that any such tax form previously provided by Dealer has become obsolete or incorrect. Additionally, Dealer shall, promptly upon request by Counterparty, provide such other tax
forms and documents as are reasonably requested by Counterparty. 

  
 19 

 (iv) Tax Representations. Counterparty is a corporation for U.S. federal
income tax purposes and is organized under the laws of the State of Delaware. Counterparty is a “U.S. person” (as that term is used in section 1.1441-4(a)(3)(ii) of United States Treasury Regulations) for U.S. federal income tax purposes
and an exempt recipient under Treasury Regulation Section 1.6049-4(c)(1)(ii). 
 (q) 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 THE TRANSACTION OR THE ACTIONS OF DEALER OR ITS AFFILIATES IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF. 

(r) Governing Law; Jurisdiction. THIS CONFIRMATION AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR
RELATED TO THIS CONFIRMATION SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 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.
