 2. Section 2.04 of the Plan is amended to read as follows: 

2.04 “Active Participant” A. for a Plan Year means a Participant who is employed by an Employer as an Eligible Employee
for any portion of the Plan Year; provided, however that (i) for purposes of making Elective Deferrals under Section 4.01 (including Roth Contributions under Section 4.01(b)), a Participant will not be an Active
Participant for a Plan Year unless he or she has Compensation in the Plan Year; (ii) for purposes of Company Contributions under Section 4.03, Traveler Contributions under Section 4.04(a)(ii), and any minimum contributions required
under Article XII, a Participant will not be an Active Participant for the Plan Year unless he or she is an Employee on the last day of the Plan Year or had a Termination of Employment during the Plan Year by reason of Retirement, Disability, death,
a Reduction-in-Force Termination or lay-off; and (iii) for purposes of Company Contributions under Section 4.03, a Participant will not be Active Participant for the Plan Year unless he or she has completed 1,000 or more Hours of Service
during the Plan Year, or had a Termination of Employment during the Plan Year by reason of Retirement, Disability, death, or a Reduction-in-Force Termination. 
 3. Section 2.52 of the Plan is amended to read as follows: 
 2.52
“Rollover Contribution” means a contribution made from time to time by an Eligible Employee to the Trustee in accordance with Section 4.05 of the Plan (i) from a qualified trust as described in Section 402(c) of the
Code, an annuity contract described in Section 403(b) of the Code or an eligible plan under Section 457(b) of the Code which is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or
political subdivision of a state; or (ii) from an individual retirement account or individual retirement annuity (“IRA”) as described in Section 408(d)(3) of the Code if the sole source of contributions to such IRA was one or
more rollover contributions from a qualified trust described in Section 402(c) of the Code. A Rollover Contribution shall include any direct transfer of an eligible rollover distribution described in Section 401(a)(31) of the Code from a
qualified trust, annuity contract, eligible governmental plan or IRA described in the preceding sentence. Effective February 1, 2011, a Rollover Contribution shall include any direct transfer to the Participant’s Roth Rollover Account from
another Roth elective deferral account under an applicable plan described in Section 402A(e)(1) of the Code, but only to the extent the Rollover Contribution is permitted under the rules of Section 402A(c) of the Code. 

4. A new Section 2.52A is added to the Plan to read as follows: 

2.52A “Roth Contribution” means that portion of a Participant’s Elective Deferrals that the Participant designates
as a Roth Contribution in the Participant’s Salary Reduction Agreement and that is contributed to the Plan on an after-tax basis in accordance with Section 4.01(b). 
 5. Section 2.54 of the Plan is amended to read as follows: 
 2.54
“Service” means the aggregate of all periods of employment of an Employee by an Employer or Related Company (including periods of Authorized Leave of Absence) measured from the date an Employee first performs an Hour of Service upon
employment or reemployment to the date of the Employee’s Termination of Employment, but excluding any Period of Severance other than an Authorized Leave of Absence; provided, however, that (i) an Employee shall not be
credited with more than 12 months of Service with respect to any single period of Authorized Leave of Absence; and (ii) if an Employee who has a Termination of Employment is reemployed by an Employer or a Related Company and performs an Hour of
Service before he or she incurs a one-year Period of Severance, such Termination of Employment shall be disregarded and his or her Service shall be treated as continuous through the date he or she resumes employment as an Employee. An Employee shall
receive credit for 1/12 of a year of Service for each full or partial calendar month of Service. Service once credited under this Section shall not be disregarded by reason of any subsequent Period of Severance; except that if a 

  
 1 

 
Participant has five consecutive one-year Periods of Severance, Service after such five-year period shall not be taken into account for purposes of Section 4.10 in determining the
nonforfeitable percentage of his or her Accrued Benefit derived from Employer contributions which accrued before such five-year period. For purposes of determining whether or to what extent a Participant’s Accounts transferred from a Transferor
Plan are vested and nonforfeitable under Section 4.11, Service of a Participant who was a participant in a Transferor Plan shall include service with the predecessor employer credited for vesting purposes under the Transferor Plan. For purposes
of determining whether or to what extent Accounts of a Participant who was employed by CRI/Criterion, Inc., a Delaware corporation (“CRI”), or an employer that is a Related Company to CRI, immediately before the acquisition by an Employer
of the capital stock of Chemical Research and Licensing Company, a Texas corporation, are vested and nonforfeitable under Section 4.11, Service shall include service with CRI or such Related Company prior to such acquisition. Notwithstanding
any provision of this Plan to the contrary, contributions, benefits and service credit with respect to Qualified Military Leave shall be provided in accordance with Section 414(u) of the Code, effective as of December 12, 1994. 

6. Section 4.01 of the Plan is amended to read as follows: 
 4.01 Elective Deferrals. 
 (a) General. Each Active
Participant may elect to make Elective Deferrals from his or her Compensation, and may designate the portion, if any, of the Elective Deferrals to be contributed as Roth Contributions, at least annually during any Plan Year and at such other times
as the Plan Administrator may prescribe, by executing and filing an appropriately completed Salary Reduction Agreement with the Plan Administrator on such form or forms provided or permitted by the Plan Administrator and in such manner as the Plan
Administrator may prescribe. The Salary Reduction Agreement shall specify the percentage of Compensation to be contributed to the Plan as Elective Deferrals and the portion, if any, of the Elective Deferrals to be contributed as Roth Contributions.
The percentage for Elective Deferrals shall not be more than the maximum percentage for Elective Deferrals prescribed by the Plan Administrator from time to time uniformly applicable to all Participants and effective from and after the date
prescribed. Except for that portion, if any, of the Elective Deferrals that the Participant has designated as Roth Contributions in accordance with subsection (b) below, such contribution shall be on a pre-tax basis, and the Employer shall
reduce each Participant’s Compensation by, and contribute to the Trust as Elective Deferrals on behalf of such Participant, the amount (if any) by which the Compensation available to the Participant (after applicable deductions) has been
reduced under such Participant’s Salary Reduction Agreement. A Participant’s Salary Reduction Agreement shall continue in effect, subject to subsection (f) below, notwithstanding any change in his or her Compensation, until he or she
changes or revokes his or her Salary Reduction Agreement. 
 (b) Roth Contributions. If the Participant
affirmatively designates a portion of his or her Elective Deferrals as Roth Contributions, such amount will be deducted from his or her Compensation on an after-tax basis, subject to withholding of applicable Federal, state and local income taxes on
such Roth Contributions from the Participant’s Compensation other than such Roth Contributions. Except as provided in the preceding sentence or otherwise expressly specified in this Plan, Roth Contributions shall be treated as Elective
Deferrals (or Catch-Up Contributions, as applicable), for all purposes of this Plan. In the absence of an affirmative designation, none of the Participant’s Elective Deferrals under this Plan shall be contributed as Roth Contributions.

 (c) Changes of Salary Reduction Agreements. A Participant may change his or her rate of Elective
Deferrals, or the designation of any portion of Elective Deferrals as Roth Contributions, by executing and filing a new Salary Reduction Agreement with the Plan 

  
 2 

 
Administrator on such form provided or permitted by the Plan Administrator and in such manner as the Plan Administrator may prescribe. 

(d) Effective Date of Salary Reduction Agreement. A Salary Reduction Agreement or a change thereof shall apply
solely to Compensation not yet paid or payable as of the date such new or changed Salary Reduction Agreement is filed with the Plan Administrator. Subject to the foregoing requirement, a Salary Reduction Agreement or change thereof shall take effect
on the first day of the payroll period as of which the start or change of the Participant’s Elective Deferrals, or the designation of any portion of Elective Deferrals as Roth Contributions, is administratively practicable (determined under
procedures established by the Plan Administrator) after the Participant has executed and filed an initial or changed Salary Reduction Agreement with the Plan Administrator as provided in subsection (a) or (c) of this Section 4.01.

 (e) Revocations of Salary Reduction Agreements. A Participant may revoke a Salary Reduction Agreement
with respect to Compensation not paid or payable as of the date of such revocation by executing and filing a revocation of such Salary Reduction Agreement on such form provided or permitted by the Plan Administrator and in such manner as the Plan
Administrator may prescribe. Revocation of a Salary Reduction Agreement shall take effect on the first day of the payroll period as of which implementing the revocation is administratively practicable (determined under procedures established by the
Plan Administrator) after the Participant has executed and filed such revocation with the Plan Administrator. A Participant’s Salary Reduction Agreement shall become ineffective upon his or her ceasing to be an Active Participant. But the
Participant may make a new Salary Reduction Agreement in accordance with subsection (a) upon again becoming an Active Participant. 
 (f) Other Reductions and Limitations. Elective Deferrals shall not exceed the lowest maximum amount permitted by Article V. Notwithstanding anything in a Salary Reduction Agreement, the Plan
Administrator may reduce the Elective Deferrals and amend the Salary Reduction Agreement of any Participant to prevent a reasonably anticipated violation of the limitations of Section 5.07, and may reduce the Elective Deferrals and Salary
Reduction Agreement of any Participant who is a Highly Compensated Employee to prevent a reasonably anticipated violation of the limitations of Sections 5.01 or 5.02. Any reduction of Elective Deferrals under this subsection (f) shall be
applied pro rata to Elective Deferrals that are not Roth Contributions and to Elective Deferrals that are Roth Contributions. If a Participant receives a Hardship distribution pursuant to Section 7.01, his or her Salary Reduction Agreement
shall be suspended in accordance with Section 7.01(c)(5). The Plan Administrator may, in its discretion, impose such additional rules, regulations and limitations on the amount of Elective Deferrals that may be elected, including limitations on
the amount of Elective Deferrals that an Active Participant may elect for each payroll period to a pro-rata portion of the Dollar Limit, and limitations on the amount of Elective Deferrals that a Highly Compensated Employee may elect, to ensure that
the limitations of Article V are not exceeded. 
 (g) Time for Contributing Elective Deferrals. For each
payroll period during a Plan Year, each Employer shall pay the Elective Deferrals of Participants who are its Employees over to the Trustee as of, or as soon as reasonably possible after, the date such amount would otherwise have been paid to the
Participant in cash; but not earlier (except as required by bona fide administrative considerations) than the date that the Participant performs the services with respect to which the contribution is made (or the date such amount would otherwise
have been paid to the Participant in cash, if earlier), and not later than the 15th business day of the month following the month in which such amount would otherwise have been paid to the Participant in cash. 

  
 3 

 (h) Allocation of Elective Deferrals. Elective Deferrals that are not
Roth Contributions shall be allocated to the Employee 401(k) Account of each Participant on whose behalf such Elective Deferrals were made. Elective Deferrals that are Roth Contributions shall be allocated to the Roth Contribution Account of each
Participant on whose behalf such Roth Contributions were made. 
 7. Section 4.02(a) of the Plan is amended to read as
follows: 
 (a) General. Subject to Sections 11.01, 11.02 and 11.04, for each Plan Year, each Employer
shall contribute on behalf of each Participant employed by the Employer on whose behalf Elective Deferrals (whether or not designated as Roth Contributions) are made, an amount equal to one hundred percent (100%) of so much of the
Participant’s Elective Deferrals for the Plan Year as do not exceed three percent (3%) of the Participant’s Compensation for the Plan Year, or such larger or smaller percentages as each Employer may determine uniformly for the
Participants who are its Employees. An Employer may change such percentages from time to time during the Plan Year, provided that the Employer may not retroactively decrease the percentages of its Matching Contributions or the percentage of Elective
Deferrals subject to Matching Contributions. 
 8. Section 4.05 of the Plan is amended to read as follows: 

4.05 Rollover Contributions into the Plan. At the request of any Eligible Employee the Plan Administrator shall direct the Trustee
to accept a Rollover Contribution on behalf of the Eligible Employee. Unless the Rollover Contribution is a direct transfer from another Roth elective deferral account under an applicable retirement plan described in Section 402A(e)(1) of the
Code, the Rollover Contribution shall be held in the Prior Plan and Rollovers Account for the Eligible Employee. A Rollover Contribution that is a direct transfer from another Roth elective deferral account under an applicable retirement plan
described in Section 402A(e)(1) of the Code shall be held in the Participant’s Roth Rollover Account. If the Rollover Contribution includes amounts that would not be includible in gross income (except as provided by Sections 402(c),
403(a)(4), 403(b)(8) and 457(e)(16) of the Code and except by reason being a direct transfer from another Roth elective deferral account) if not transferred as an Rollover Contribution, the Plan Administrator shall separately account for the portion
of the Rollover Contribution which is so includible in gross income and the portion of such Rollover Contribution which is not so includible. Each Rollover Contribution shall be made in cash, in notes representing a loan to the Participant from a
qualified trust under provisions of such qualified trust similar to Section 7.02, or in property (which may be stock or securities issued by the former employer) acceptable to the Trustee in its sole discretion for purposes of this Plan. Prior
to accepting a Rollover Contribution, the Plan Administrator may require that the Eligible Employee who wants to make the Rollover Contribution shall provide evidence reasonably satisfactory to the Plan Administrator that such Contribution qualifies
as a Rollover Contribution. Acceptance of a Rollover Contribution shall not in any manner guarantee the result of such contribution under any tax laws; and neither the Company, the Investment Committee, any Employer, the Plan Administrator, the
Trustee nor any Investment Manager, shall be responsible for such tax results. If the Plan Administrator determines after any Rollover Contribution that such contribution did not in fact qualify as a Rollover Contribution, the amount of the Rollover
Contribution, increased by income and gains and reduced (but not below zero) by losses and expenses, shall be returned to the Eligible Employee. 
 9. Subsection 4.11(b) of the Plan is amended to read as follows: 

(b) Fully Vested Accounts. A Participant’s Accrued Benefit shall be fully vested and nonforfeitable at all
times to the extent represented by the balance of his or her Employee 

  
 4 

 
401(k) Account, Roth Contribution Account, Travelers Benefit Account, Rollover Account, and Roth Rollover Account. 
 10. Section 4.12 of the Plan is amended to read as follows: 
 4.12
Catch-Up Deferrals. Effective for Plan Years beginning on or after January 1, 2002, each Participant who is an “Eligible Active Participant” (as defined in subsection (a)) may elect to make Catch-Up Deferrals from his or her
Compensation, and may elect to designate all or any portion of such Catch-Up Deferrals as Roth Contributions, by written election on a Salary Reduction Form filed with the Plan Administrator in such manner as the Plan Administrator may prescribe.
The Employer shall reduce each Eligible Active Participant’s Compensation, and contribute to the Trust as Catch-Up Deferrals on behalf of such Participant, the amount (if any) of the Participant’s Catch-Up Deferrals. For purposes of this
Section 4.12: 
 (a) An “Eligible Active Participant” is a Participant who: 

(1) will have attained age 50 on or before the last day of the Plan Year; and 

(2) has made Elective Deferrals for the Plan Year that are the maximum Elective Deferrals allowed under the Plan, taking
into account the provisions of Article V. 
 (b) For each Plan Year, the amount of the Catch-Up Deferrals made
on behalf of a Participant who is an Eligible Active Participant shall be equal to the dollar amount or percentage (in increments of 1%) of the Participant’s Compensation specified by the Participant for Catch-Up Deferrals on his or her Salary
Reduction Form, provided that such Catch-Up Deferrals may not exceed the lesser of the following for a Plan Year: 
 (1) $5,500 for 2011, as adjusted for Plan Years thereafter for cost-of-living increases by the Secretary of the Treasury or his delegate pursuant to the provisions of Section 414(v)(2)(C) of the
Code; or 
 (2) The excess of (i) the Participant’s Statutory Compensation for the Plan Year as
determined under Section 2.13(b) (as applied for purposes of Sections 5.02 and 5.03), over (ii) the Participant’s Elective Deferrals for the Plan Year. 

(c) A Participant’s initial Catch-Up Deferral election shall be effective for Compensation payable on or after the
date on which such election is made and shall remain in effect until changed or revoked. Thereafter, changes in the percentage (solely in increments or decrements of 1%) or dollar amount of Compensation to be deferred or revocation of any such
election, or changes in the designation of any portion of Catch-Up Contributions as Roth Contributions, may be made by written election on a Salary Reduction Form filed with the Plan Administrator in such manner as the Plan Administrator may
prescribe. 
 (d) The Catch-Up Deferrals for the Plan Year (other than Catch-Up Deferrals designated as Roth
Contributions) shall be credited to the Participants’ Employee 401(k) Accounts, and Catch-Up Deferrals for the Plan Year designated as Roth Contributions shall be credited to the Participants’ Roth Contribution Accounts, in the amounts of
their respective Catch-Up Deferral elections for such Plan Year and the designation, if any, of any portion of such Catch-Up Deferrals as Roth Contributions. Catch-Up Deferrals shall be fully vested and nonforfeitable. 

(e) Catch-Up Deferrals shall not be subject to any of the limitations under Article V. 

  
 5 

 (f) The Plan Administrator may specify rules from time to time governing
Catch-Up Deferrals, including, but not limited to, rules regarding (i) the timing, method, and implementation dates of Catch-Up Deferral elections, (ii) the return or recharacterization of Catch-Up Deferrals as Elective Deferrals, and
(iii) the recharacterization of Elective Deferrals of an Eligible Active Participant as Catch-Up Deferrals, to the extent the Elective Deferrals of the Eligible Active Participant would otherwise exceed the limitations of Article V and the
total Catch-Up Deferrals of the Participant (after recharacterization) do not exceed the limits of subsection (b) above. Such rules shall be in compliance with any applicable guidance issued by the Secretary of the Treasury, and, to the extent
deemed advisable by the Plan Administrator in order to comply with such guidance, such rules may override any of the preceding provisions of this Section 4.12. 

(g) Catch-Up Deferrals will be treated as Elective Deferrals for all purposes of this Plan other than Section 4.02
(relating to Matching Contributions) and Article V (relating to Limitations on Contributions); provided, however, that Catch-Up Deferrals recharacterized under subsection (f) as Elective Deferrals will be eligible for Matching Contributions to
the extent provided for Elective Deferrals in Section 4.02 
 11. Section 5.01 of the Plan is amended to read as
follows: 
 5.01 Excess Deferrals. Notwithstanding Section 4.01 or anything in a Participant’s Salary Reduction
Agreement, the sum for any calendar year of (i) Elective Deferrals of any Participant under this Plan, (ii) any elective deferrals excluded from the Participant’s gross income made under a Related Plan, and (iii) the amount of
elective deferrals under any other plan if the Participant notifies the Plan Administrator in writing by March 1 of the following calendar year that such other plan exists under which elective deferrals were excluded from the Participant’s
gross income and the amount of such elective deferrals (excluding in every case Catch-Up Deferrals made under Section 4.12 of this Plan or corresponding provisions authorized by Section 414(v) of the Code of any Related Plan or other
plan), shall not exceed the applicable Dollar Limit. The “Dollar Limit” is $16,500 for 2011, as adjusted for Plan Years thereafter for cost-of-living increases by the Secretary of the Treasury or his or her delegate pursuant to Sections
402(g)(4) and 415(d) of the Code. If the sum of such amounts exceeds the Dollar Limit for a calendar year, the Plan Administrator shall, not later than the April 15 following the close of such calendar year, distribute to the Participant all or
such portion of the Participant’s Elective Deferrals in excess of the Dollar Limit (by first distributing unmatched Elective Deferrals that are not Roth Contributions, then by distributing unmatched Elective Deferrals that are Roth
Contributions, then by distributing matched Elective Deferrals that are not Roth Contributions, and finally by distributing matched Elective Deferrals that are Roth Contributions) for such calendar year in an amount equal to the greater of
(i) the amount the Plan Administrator determines is necessary to eliminate the excess of the sum of the amount described in clauses (i) and (ii) above over the, including net income and minus any loss allocable to such amount
determined in accordance with Section 5.06, or (ii) the amount requested in writing by the Participant on or before the March 1 following the close of such calendar year. Any Matching Contributions (including any net income and minus
any loss allocable thereto determined in accordance with Section 5.06) made with respect to such distributed Elective Deferrals matched Plan Administrator shall be forfeited and allocated in accordance with Section 4.10(f). 

12. Subsection 5.02(c) of the Plan is amended to read as follows: 

(c) Distribution of Excess Contributions. The Plan Administrator shall, not later than the last day of the Plan
Year next following the Plan Year in which such amounts are contributed, distribute the Total Excess Contributions (including any income earned and minus any loss allocable to such amounts determined in accordance with Section 5.6) to the
Highly Compensated Employees on whose behalf such Elective Deferrals were made. Any required 

  
 6 

 
distribution will be made first from Elective Deferrals that are not Roth Contributions and then if necessary from Elective Deferrals that are Roth Contributions. Any Matching Contributions
(including any income earned and minus any loss allocable thereto determined in accordance with Section 5.06) made with respect to such distributed Elective Deferrals shall be forfeited and allocated in accordance with Section 4.10(f).

 13. Subsection 5.07(c) of the Plan is amended to read as follows: 

(c) Elimination of Annual Excess. If a Participant has an Annual Excess for a Plan Year, such excess shall not be
allocated to the Participant’s Accounts but shall be eliminated as follows: 
 (1) Unmatched Elective
Deferrals Participant Contributions. The Participant’s unmatched Elective Deferrals (first unmatched Elective Deferrals that are not Roth Contributions and then unmatched Elective Deferrals that are Roth Contributions) for the Plan Year
shall be reduced to the extent necessary to eliminate the Annual Excess. 
 (2) Matched Elective Deferrals
and Related Matching Contributions. If any Annual Excess remains, the Participant’s matched Elective Deferrals (first matched Elective Deferrals that are not Roth Contributions and then matched Elective Deferrals that are Roth
Contributions) and the related Matching Contributions for the Plan Year shall be reduced in proportionate amounts to the extent necessary to eliminate the Annual Excess. 

(3) Company Contributions. If any Annual Excess remains, the Company Contributions for the Plan Year shall be
reduced to the extent necessary to eliminate the Annual Excess. 
 (4) QNECs or QMACs. If any Annual
Excess remains, the Participant’s QNECs or QMACs for the Plan Year shall be reduced to the extent necessary to eliminate the Annual Excess. 
 14. The first sentence of Section 7.01 is amended to read as follows: 
 A
Participant may, in accordance with this Section, withdraw all or a portion of his or her Accounts, other than his or her Roth Contribution Account, pursuant to subsection (a), (b) or (c); provided, however, that the amount withdrawn pursuant
to this Section 7.01 shall not be greater than the amount of the Participant’s vested Accrued Benefit available for withdrawal under this Section. Withdrawals shall be made pro rata from each Investment Fund in which the Account or
Accounts from which the withdrawal is paid are invested. 
 15. Subsection 7.01(a) of the Plan is amended to read as follows:

 (a) In-Service Withdrawals from Rollover Account and Certain Prior Plan Accounts. A Participant may
withdraw, in accordance with Section 7.03, for any reason, all or any portion of his or her Rollover Account or Roth Rollover Account and, subject to the restrictions imposed by Appendix A and Schedule 1, any other Inactive Account comprising
Rollover Contributions or after-tax employee contributions made under this Plan or a Transferor Plan. 

  
 7 

 16. Section 7.02(e) is amended to read as follows: 

(e) Pledge of Accounts. Any loan made pursuant to this Section 7.02 shall be made pro rata from the
Participant’s Accounts other than his or her Roth Contribution Account. If a Participant’s Account is invested in more than one Investment Fund at the time of the loan, the loan shall be made pro rata from each Investment Fund (other than
the Company Stock Fund) in which the Accounts from which the loan is disbursed are invested, except to the extent an Inactive Account is not available for loans as set forth in Schedule 1. Such loan and any accrued but unpaid interest with respect
thereto, shall constitute a first lien upon the interest of such Participant in the Accounts from and to the extent to which the loan is made and, to the extent that the loan may be unpaid at the time the Participant’s Accounts become payable,
shall be deducted from the amount payable to such Participant or his Beneficiary at the time of distribution of any portion of his or her Accounts. In the event that a Participant fails to repay a loan according to its terms and foreclosure occurs,
the Plan may foreclose on the portion of the Participant’s Accounts which secure the loan and which would be distributable to the Participant as of the earliest date on which the Participant could elect a distribution or withdrawal pursuant to
this Article or Article VII. Such foreclosed amount shall be deemed to be a distribution. 
 17. Section 8.09 (1) is
amended to read as follows: 
 (1) “Eligible Rollover Distribution” means any distribution of
all or any portion of the balance to the credit of the Distributee, except that an Eligible Rollover Distribution does not include any distribution that is one of a series of substantially equal periodic payments (not less frequently than annually)
made for the life (or life expectancy) of the Distributee or the joint lives (or joint life expectancies) of the Distributee and the Distributee’s designated Beneficiary, or for a specified period of ten years or more; any distribution to the
extent such distribution is required under Section 8.06(b); any distribution by reason of Hardship pursuant to Section 7.01(b); and except as provided in the following sentence the portion of any distribution that is not includable in
gross income (determined without regard to the exclusion for net unrealized appreciation with respect to employer securities). A portion of a distribution shall not fail to be an Eligible Rollover Distribution merely because the portion consists of
after-tax employee contributions which are not includable in gross income. However, such portion may be transferred only to an individual retirement account or annuity described in Section 408(a) or (b) of the Code, or to a qualified
defined contribution plan described in Section 401(a) or 403(a) of the Code that agrees to separately account for amounts so transferred, including separately accounting for the portion of such distribution which is includable in gross income
and the portion of such distribution which is not so includable. Effective January 1, 2011, a portion of a distribution will not fail to be an eligible rollover distribution merely because the portion consists of all or a portion of the
Participant’s Roth Contribution Account or Roth Rollover Account. However, such portion may be transferred only to another Roth elective deferral account under an applicable retirement plan described in Section 402A(e)(1) of the Code or to
a Roth IRA described in Section 408A of the Code, and only to the extent the direct rollover is permitted under the rules of Section 402(c) of the Code.

 18. The amendments made by Paragraphs 1 and 2, 4 through 7, and 9 through 17, shall be
effective January 1, 2011. The amendments made by Paragraphs 3 and 8 shall be effective February 1, 2011.

shares of Common Stock were issued and sold (the “Sold Units”) thereunder. The Company proposes to issue and sell from time to time through the Agent an offering of up to 7,551,317 shares (the “Shares”) of its
Common Stock, by any method permitted by law deemed to be an “at-the-market” offering as defined in Rule 415 of the Securities Act (as defined below), including, without limitation, sales made directly on the New York Stock Exchange (the
“NYSE”), on any other existing trading market for the Shares or to or through a market maker (the “ATM Program”). 
 It is understood and agreed by the parties hereto that: (a) the representations, warranties, agreements, indemnities and covenants applicable to the sale of the Sold Units are limited to those as set
forth in the Prior Sales Agreement, and (b) that the Shares offered hereby and hereunder are not governed by, and are in addition to and do not include the Sold Units offered pursuant to, the Prior Sales Agreement. 

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) an
automatic shelf registration statement on Form S-3 (File No. 333-160852), which contains a base prospectus (the “Base Prospectus”) to be used in connection with the public offering and sale of securities (the
“Shelf Securities”), including the Shares, to be issued from time to time by the Company. Such registration statement, filed with the Commission under the Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (collectively, the “Securities Act”), including the financial statements, exhibits and schedules thereto and all documents incorporated or deemed to be incorporated by reference therein and any information deemed to be a
part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange
Act”), is called the “Registration Statement.” As used herein, the term “Prospectus” shall mean the prospectus supplement to the Base Prospectus that describes the Shares and the offering thereof pursuant
to the ATM Program (the “Prospectus Supplement”), together with the Base Prospectus, in the form 

 
first used by the Agent to confirm sales of the Shares pursuant to the ATM Program or in the form first made available to the Agent by the Company to meet requests of purchasers pursuant to Rule
173 under the Securities Act. As used herein, “Applicable Time” is 10:00 a.m. (New York time) on July 21, 2011. As used herein, “free writing prospectus” has the meaning set forth in Rule 405 under the
Securities Act, and “Time of Sale Prospectus” means the Prospectus, as amended or supplemented immediately prior to the later to occur of (i) the Applicable Time and (ii) the Time of Sale (as defined below), together with
the free writing prospectuses, if any, identified in Schedule I hereto. As used herein, the terms “Registration Statement,” “Base Prospectus,” “Prospectus Supplement,” “Time of Sale Prospectus” and
“Prospectus” shall include the documents incorporated and deemed to be incorporated by reference therein. All references in this Agreement to amendments or supplements to the Registration Statement, the Base Prospectus, the Prospectus
Supplement, the Time of Sale Prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Exchange Act which is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus,
the Prospectus Supplement, the Time of Sale Prospectus or the Prospectus, as the case may be. All references in this Agreement to (i) the Registration Statement, the Base Prospectus, the Prospectus Supplement or the Prospectus, or any
amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”) and (ii) the Prospectus shall be
deemed to include the “electronic Prospectus” provided for use in connection with the offering of the Shares as contemplated by Section 5(p) of this Agreement. All references in this Agreement to financial statements and
schedules and other information which are “contained,” “included” or “stated” in the Registration Statement, the Base Prospectus, the Prospectus Supplement, the Time of Sale Prospectus or the
Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement or the
Prospectus, as the case may be. 
 The Company hereby confirms its agreements with the Agent as follows:

 Section 1. Representations and Warranties. 

The Company hereby represents, warrants and covenants to the Agent, as of the date of this Agreement and on each such
time the following representations and warranties are repeated or deemed to be made pursuant to this Agreement, as follows: 
 (a) Compliance with Registration Requirements. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment to the Registration Statement for the
purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at
the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) under the Securities Act) made any offer relating to the Shares in reliance on the exemption of Rule 163 under the Securities Act,
(iv) as of each time the Shares are sold pursuant to this Agreement (each, a “Time of Sale”), (v) at each Settlement Date (as defined below) and (vi) at all times during which a prospectus is required by the
Securities Act to be delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule) in connection with any offer or sale of the Shares (the “Delivery Period”), the Company was a
“well-known seasoned issuer” as defined in Rule 405 under the Securities Act, including not having been an “ineligible issuer” as defined in Rule 405 under the Securities Act. 

The Registration Statement is an “automatic shelf registration statement,” as defined in Rule
405, which became effective on July 29, 2009. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) under the Securities Act objecting to the Company’s use of the

  
 2 

 
automatic shelf registration form. No stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending
or, to the best knowledge of the Company, are contemplated or threatened by the Commission. 

At the time the Registration Statement was originally declared effective and at the time the
Company’s Annual Report on Form 10-K for the year ended December 31, 2010 (the “Annual Report”) was filed with the Commission, the Company met the then applicable requirements for use of Form S-3 under the
Securities Act. The Company meets the requirements for use of Form S-3 under the Securities Act specified in Conduct Rule 5110(b)(7)(C)(i) of the Financial Industry Regulatory Authority Inc. (“FINRA”). 

The Prospectus when filed complied in all material respects with the Securities Act and, if filed by
electronic transmission pursuant to EDGAR (except as may be permitted by Regulation S-T under the Securities Act), was identical to the copy thereof delivered to the Agent for use in connection with the offer and sale of the Shares. The
Registration Statement and any post-effective amendment thereto, at the time it became or becomes effective, complied or will comply in all material respects with the Securities Act and did not and will not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Applicable Time, the Time of Sale Prospectus did not, and at each Time of Sale and Settlement Date and at any
such time this representation is repeated or deemed to be made pursuant to this Agreement, the Time of Sale Prospectus, as then amended or supplemented by the Company, if applicable, will not, contain any untrue statement of a material fact or omit
to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus, as amended or supplemented, as of its date, did not and will not contain any 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 set forth in the three
immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus or the Time of Sale Prospectus, or any amendments or supplements thereto, made in
reliance upon and in conformity with information relating to the Agent furnished to the Company in writing by the Agent expressly for use therein, it being understood and agreed that the only such information furnished by the Agent to the Company
consists of the information described in Section 11(b) below. 
 At the earliest
time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Securities Act) of the Shares and as of the date of this Agreement, the
Company was not and is not an “ineligible issuer” in connection with the offering of the Shares pursuant to Rules 164, 405 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule
433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under
the Securities Act or that was prepared by or behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of Rule 433 under the Securities Act, including timely filing with the Commission or
retention where required and legending, and each such free writing prospectus, as of its issue date did not include any information that conflicted, conflicts with or will conflict with the information contained in the Registration Statement (as
amended or supplemented as of such date), including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. Except for the free writing prospectuses, if any,
identified in Schedule I hereto, the Company has not prepared, used or referred to, and will not, without your prior consent, prepare, use or refer to, any free writing prospectus with respect to the ATM Program. 

  
 3 

 (b) Offering Materials Furnished to the Agent. The
Company has delivered to the Agent one complete copy of the Registration Statement, each amendment thereto and of each consent and certificate of experts filed as a part thereof, and conformed copies of the Registration Statement, each amendment
thereto, the Time of Sale Prospectus, the Prospectus, as amended or supplemented, and any free writing prospectus reviewed and consented to by the Agent, in such quantities and at such places as the Agent has reasonably requested. 

(c) Distribution of Offering Material by the Company. The Company has not distributed and will not
distribute, prior to the completion of the Agent’s distribution of the Shares, any offering material in connection with the offering and sale of the Shares other than a Time of Sale Prospectus, the Prospectus, any free writing prospectus
reviewed and consented to by the Agent, or the Registration Statement. 
 (d) The Sales
Agency Agreement. This Agreement has been duly authorized, executed and delivered by, and is a valid and binding agreement of, the Company, enforceable in accordance with its terms, except as rights to indemnification hereunder may be limited by
applicable law and except as the enforcement hereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles.

 (e) Corporate Records. All existing minute books of the Company and its subsidiaries,
including all existing minutes of all meetings and actions of the board of directors (including Audit, Compensation, Nominating and Governance and other board committees) and stockholders of the Company through the date of the latest meeting and
action (collectively, the “Corporate Records”) have been made available to the Agent and counsel to the Agent. All such Corporate Records are complete and accurate and accurately reflect, in all material respects, all transactions
referred to in such Corporate Records. There are no material transactions, agreements or other actions of the Company and its subsidiaries that are not properly approved or recorded in the Corporate Records. 

(f) Authorization of the Shares. The Shares have been duly authorized for issuance and sale
pursuant to this Agreement and, when issued and delivered by the Company pursuant to this Agreement, will be validly issued, fully paid and nonassessable, and the issuance and sale of the Shares is not subject to any preemptive rights, rights of
first refusal or other similar rights to subscribe for or purchase the Shares. 
 (g) No
Applicable Registration or Other Similar Rights. There are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated
by this Agreement. 
 (h) No Material Adverse Change. Except as otherwise disclosed in
the Time of Sale Prospectus, subsequent to the respective dates as of which information is given in the Time of Sale Prospectus: (i) there has been no material adverse change, or any development that could reasonably be expected to result in a
material adverse change, in the condition, financial or otherwise, or in the earnings, business or operations, whether or not arising from transactions in the ordinary course of business, of the Company and its subsidiaries, considered as one entity
(any such change is called a “Material Adverse Change”); (ii) the Company and its subsidiaries, considered as one entity, have not incurred any material liability or obligation, indirect, direct or contingent, not in the
ordinary course of business nor entered into any material transaction or agreement not in the ordinary course of business; 

  
 4 

 
and (iii) there has been no dividend or distribution of any kind declared, paid or made by the Company or, except for dividends or distributions declared, paid or made by the Company or
other subsidiaries, to or among or between the Company or any of its subsidiaries on or with respect to any class of capital stock or repurchase or redemption by the Company or any of its subsidiaries of any class of capital stock or otherwise.

 (i) Independent Accountants. As of the Applicable Time, Ernst & Young LLP,
who have expressed their opinion with respect to the financial statements (which term as used in this Agreement includes the related notes thereto) and supporting schedules filed with the Commission as a part of the Registration Statement and
included in the Prospectus, are independent public or certified public accountants as required by the Securities Act and the Exchange Act. 
 (j) Preparation of the Financial Statements. The financial statements incorporated by reference in the Registration Statement or any Time of Sale Prospectus or Prospectus (each, an
“Applicable Prospectus”) present fairly the consolidated financial position of the Company and its subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified. The
supporting schedules included in the Registration Statement present fairly the information required to be stated therein. Such financial statements and supporting schedules have been prepared in conformity with generally accepted accounting
principles as applied in the United States applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto. No other financial statements or supporting schedules are required under the
Securities Act to be included in the Registration Statement or any Applicable Prospectus. 
 (k)
Company’s Accounting System. The Company and each of its subsidiaries make and keep accurate books and records and maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions
are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles as
applied in the United States and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is
compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Since December 31, 2008, there has not been and is no material weakness in the Company’s internal control over
financial reporting (whether or not remediated) and since December 31, 2010, there has been 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. 
 (l) Incorporation
and Good Standing of the Company and its Subsidiaries. Each of the Company and its subsidiaries has been duly incorporated or organized, as the case may be, and is validly existing as a corporation, partnership or limited liability company, as
applicable, in good standing under the laws of the jurisdiction of its incorporation or organization except where the failure to do so would not reasonably be expected to cause a Material Adverse Change, and has the power and authority (corporate or
other) to own, lease and operate its properties and to conduct its business as described in each Applicable Prospectus and, in the case of the Company, to enter into and perform its obligations under this Agreement. Each of the Company and each
subsidiary (for the purposes of this Agreement, “subsidiaries” shall mean the subsidiaries listed on Exhibit 21 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010, as amended by
Amendment No. 1 on Form 10-K/A filed on March 31, 2011, and “subsidiary” shall mean any one of them) is duly qualified as a foreign corporation, partnership or limited liability company, as applicable, to transact business
and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of 

  
 5 

 
business except where the failure to do so would not reasonably be expected to cause a Material Adverse Change. All of the issued and outstanding capital stock or other equity or ownership
interests of each subsidiary have been duly authorized and validly issued, are fully paid and nonassessable and are owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance
or adverse claim. The Company does not own or control, directly or indirectly, any corporation, association or other entity other than (i) the subsidiaries listed in Exhibit 21 to the Company’s Annual Report on Form 10-K for the
fiscal year ended December 31, 2010, as amended by Amendment No. 1 on Form 10-K/A filed on March 31, 2011, and (ii) such other entities omitted from Exhibit 21 which, when such omitted entities are considered in the aggregate as
a single subsidiary, would not constitute a “significant subsidiary” within the meaning of Rule 1-02(w) of Regulation S-X. 
 (m) Capitalization and Other Capital Stock Matters. The authorized, issued and outstanding capital stock of the Company is as set forth in each Applicable Prospectus as of the dates referred to
therein. The Common Stock of the Company (including the Shares) conform in all material respects to the description thereof contained in the Time of Sale Prospectus. All of the issued and outstanding common stock of the Company (including the
Shares) have been duly authorized and validly issued, are fully paid and nonassessable and have been issued in compliance with federal and state securities laws. None of the outstanding common stock of the Company (including the Shares) was issued
in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company. There are no authorized or outstanding options, warrants, preemptive rights, rights of first refusal or
other rights to purchase, or equity or debt securities convertible into or exchangeable or exercisable for, any capital stock of the Company or any of its subsidiaries other than those accurately described in each Applicable Prospectus. The
description of the Company’s stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder, set forth in each Applicable Prospectus accurately and fairly presents the information required to
be shown with respect to such plans, arrangements, options and rights. 
 (n) Dividend
Restrictions. Except as set forth on Schedule III, no subsidiary of the Company is prohibited or restricted, directly or indirectly, from paying dividends to the Company, or from making any other distribution with respect to such
subsidiary’s equity securities or from repaying to the Company or any other subsidiary of the Company any amounts that may from time to time become due under any loans or advances to such subsidiary from the Company or from transferring any
property or assets to the Company or to any other subsidiary. 
 (o) Stock Exchange Listing;
Exchange Act Registration; Shareholder Approval. The Common Stock (including the Shares) is registered pursuant to Section 12(g) of the Exchange Act and are listed on the NYSE, and the Company has taken no action designed to, or likely to
have the effect of, terminating the registration of the Common Stock (including the Shares) under the Exchange Act or delisting the Common Stock (including the Shares) from the NYSE, nor has the Company received any notification that the Commission
or the NYSE is contemplating terminating such registration or listing. The Company is in compliance with all applicable corporate governance requirements of the NYSE that are currently in effect. No approval of the shareholders of the Company under
the rules and regulations of the NYSE is required for the Company to issue and deliver the Shares pursuant to this Agreement. Any certificate signed by or on behalf of the Company by an authorized representative and delivered to the Agent or to
counsel for the Agent shall be deemed to be a representation and warranty by the Company to the Agent as to the matters covered thereby. 
 (p) Non-Contravention of Existing Instruments; No Further Authorizations or Approvals Required. Neither the Company nor any of its subsidiaries is (i) in violation of its charter or by-laws,
partnership agreement or operating agreement or similar organizational document, as applicable, 

  
 6 

 
(ii) in default (or, with the giving of notice or lapse of time, would be in default) (“Default”) under any indenture, mortgage, loan or credit agreement, note, contract,
franchise, lease or other instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound (including, without limitation, any credit agreement, indenture, pledge agreement, security agreement or other
instrument or agreement evidencing, guaranteeing, securing or relating to indebtedness of the Company or any of its subsidiaries ), or to which any of the property or assets of the Company or any of its subsidiaries is subject (each, an
“Existing Instrument”), or (iii) in violation in any respect of any statute, law, rule, regulation, ordinance, judgment, order or decree of any court, regulatory body, administrative agency, governmental body, arbitrator or
other authority having jurisdiction over the Company or its subsidiaries, or any of their properties, as applicable, except with respect to clauses (ii) and (iii), for any violations, breaches or Defaults as would not, individually or in the
aggregate, result in a Material Adverse Change. The Company’s execution, delivery and performance of this Agreement, consummation of the transactions contemplated hereby and by each Applicable Prospectus and the issuance and sale of the Shares
(i) have been duly authorized by all necessary corporate action and will not result in any violation of the provisions of the charter or by-laws, partnership agreement or operating agreement or similar organizational document of the Company or
any subsidiary, as applicable, (ii) will not conflict with or constitute a breach of, or Default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its
subsidiaries pursuant to, or require the consent of any other party to, any Existing Instrument and (iii) will not result in any violation of any law, administrative regulation or administrative or court decree applicable to the Company or any
subsidiary. No consent, approval, authorization or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency, is required for the Company’s execution, delivery and performance of this
Agreement and consummation of the transactions contemplated hereby and by each Applicable Prospectus, except such as have been obtained or made by the Company and are in full force and effect under the Securities Act, applicable state securities or
blue sky laws. 
 (q) No Material Actions or Proceedings. There are no legal or
governmental actions, suits or proceedings pending or, to the best of the Company’s knowledge, threatened (i) against or affecting the Company or any of its subsidiaries, (ii) which have as the subject thereof any officer or director
of, or property owned or leased by, the Company or any of its subsidiaries or (iii) relating to environmental or discrimination matters, where in any such case (A) there is a reasonable possibility that such action, suit or proceeding
might be determined adversely to the Company, such subsidiary or such officer or director, or (B) any such action, suit or proceeding, if so determined adversely, would reasonably be expected to result in a Material Adverse Change or adversely
affect the consummation of the transactions contemplated by this Agreement. No material labor dispute with the employees of the Company or any of its subsidiaries exists or, to the best of the Company’s knowledge, is threatened or imminent.

 (r) Intellectual Property Rights. The Company and its subsidiaries own or possess
sufficient trademarks, trade names, patent rights, copyrights, domain names, licenses, approvals, trade secrets and other similar rights (collectively, “Intellectual Property Rights”) reasonably necessary to conduct their businesses
as now conducted; and the expected expiration of any of such Intellectual Property Rights would not result in a Material Adverse Change. Neither the Company nor any of its subsidiaries has received, or has any reason to believe that it will receive,
any notice of infringement or conflict with asserted Intellectual Property Rights of others, except for such notices as would not reasonably be expected to cause a Material Adverse Change. The Company is not a party to or bound by any options,
licenses or agreements with respect to the Intellectual Property Rights of any other person or entity that are required under the Securities Act to be set forth in the Prospectus and are not described therein. To the knowledge of the Company, none
of the technology employed by the Company or any of its subsidiaries has been obtained or is being used by the Company or any of its 

  
 7 

 
subsidiaries in violation of any contractual obligation binding on the Company or any of its subsidiaries or, to the Company’s knowledge, any of its or its subsidiaries’ officers,
directors or employees or otherwise in violation of the rights of any persons, except as would not reasonably be expected to cause a Material Adverse Change. 

(s) All Necessary Permits, etc. The Company and each subsidiary possess such valid and current
certificates, authorizations or permits issued by the appropriate state, federal, municipal or foreign regulatory agencies or bodies necessary to conduct their respective businesses except for those that the failure to have would not reasonably be
expected to cause a Material Adverse Change, and neither the Company nor any subsidiary has received, or has any reason to believe that it will receive, any notice of proceedings relating to the revocation or modification of, or non-compliance with,
any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could result in a Material Adverse Change. 

(t) Title to Properties. The Company and each of its subsidiaries has good and marketable title to
all of the real and personal property and other assets reflected as owned in the financial statements referred to in Section 1(j) above (or elsewhere in any Applicable Prospectus), in each case free and clear of any security interests,
mortgages, liens, encumbrances, equities, adverse claims and other defects, except such as do not materially and adversely affect the value of such property and do not materially interfere with the use made or proposed to be made of such property by
the Company or such subsidiary. The real property, improvements, equipment and personal property held under lease by the Company or any subsidiary are held under valid and enforceable leases, with such exceptions as are not material and do not
materially interfere with the use made or proposed to be made of such real property, improvements, equipment or personal property by the Company or such subsidiary. 

(u) Tax Law Compliance. The Company and its subsidiaries have filed all necessary federal, state
and foreign income and franchise tax returns and have paid all taxes required to be paid by any of them and, if due and payable, any related or similar assessment, fine or penalty levied against any of them. The Company has made such charges,
accruals and reserves in the applicable financial statements referred to in Section 1(j) above as are required by generally accepted accounting principles in the United States in respect of all federal, state and foreign income and
franchise taxes for all periods as to which the tax liability of the Company or any of its subsidiaries has not been finally determined. 
 (v) Company Not an “Investment Company”. The Company has been advised of the rules and requirements under the Investment Company Act of 1940, as amended (the “Investment
Company Act”). The Company is not, and will not be, either after receipt of payment for the Shares or after the application of the proceeds therefrom as described under “Use of Proceeds” in each Applicable Prospectus, an
“investment company” within the meaning of Investment Company Act and will conduct its business in a manner so that it will not become subject to the Investment Company Act. 

(w) Insurance. Each of the Company and its subsidiaries are insured by recognized, financially
sound and reputable institutions with policies in such amounts and with such deductibles and covering such risks as are generally deemed adequate and customary for their businesses. The Company has no reason to believe that it or any subsidiary will
not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to 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 subsidiary has been denied any insurance coverage which it has sought or for which it has applied. 

  
 8 

 (x) No Price Stabilization or Manipulation; Compliance
with Regulation M. The Company has not taken, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of the Common Stock or any other
“reference security” (as defined in Rule 100 of Regulation M under the 1934 Act (“Regulation M”)) whether to facilitate the sale or resale of the Shares or otherwise, and has taken no action which would directly or
indirectly violate Regulation M. 
 (y) Related Party Transactions. There are no business
relationships or related-party transactions involving the Company or any of its subsidiaries or any other person required under the Securities Act to be described in each Applicable Prospectus which have not been described as required. 

(z) Compliance with Laws. The Company has not been advised, and has no reason to believe, that it
and each of its subsidiaries are not conducting business in compliance with all applicable laws, rules and regulations of the jurisdictions in which it is conducting business, except where failure to be so in compliance would not result in a
Material Adverse Change. 
 (aa) Exchange Act Compliance. The documents incorporated or
deemed to be incorporated by reference in the Time of Sale Prospectus and the Prospectus, 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 Exchange Act,
and, when read together with the other information in the Time of Sale Prospectus and Prospectus, at the time the Registration Statement and any amendments thereto become effective and on each such time the following representations and warranties
are repeated or deemed to be made pursuant to this Agreement, as the case may be, after giving effect to the latest amendments or supplements to the Registration Statement, Time of Sale Prospectus or Prospectus, will not contain an untrue statement
of a material fact or omit to state a material fact required to be stated therein or necessary to make the fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made,
not misleading. 
 (bb) Sarbanes-Oxley Compliance. The Company is in compliance with all
applicable provisions of the Sarbanes-Oxley Act of 2002 and all rules and regulations promulgated thereunder or implementing the provisions thereof (the “Sarbanes-Oxley Act”) that are currently in effect. 

(cc) FINRA Matters. All of the information provided to the Agent or to counsel for the Agent by
the Company in connection with letters, filings or other supplemental information provided to FINRA pursuant to FINRA’s Rule 5110, 5190 or 5121 is true, complete and correct. 

(dd) Statistical and Market-Related Data. The statistical, demographic and market-related data
included in the Registration Statement and each Applicable Prospectus are based on or derived from sources that the Company believes to be reliable and accurate or represent the Company’s good faith estimates that are made on the basis of data
derived from such sources. 
 (ee) Disclosure Controls and Procedures; Deficiencies in or
Changes to Internal Control Over Financial Reporting. The Company has established and maintains disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)), which (i) are designed to ensure that
material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the
periods in which the periodic reports required under the Exchange Act are being prepared; (ii) have been evaluated by management of the Company for effectiveness as of the end of the Company’s most recent fiscal quarter; and (iii) are
effective in all material respects to perform the functions for which they were established. The Company is not aware of (i) any significant deficiencies or material weaknesses in the design or operation of internal control over

  
 9 

 
financial reporting which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information or (ii) any fraud, whether or
not material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting. The Company is not aware of any change in its internal control over financial reporting that has
occurred during its most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. 

(ff) Compliance with Environmental Laws. Except as described in each Applicable Prospectus and
except as would not, singly or in the aggregate, result in a Material Adverse Change, (i) neither the Company nor any of its subsidiaries is in violation of any 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 judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including,
without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants,
wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of
Hazardous Materials (collectively, “Environmental Laws”), (ii) the Company and its subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with
their requirements, (iii) there are no pending or threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any
Environmental Law against the Company or any of its subsidiaries and (iv) there are no events or circumstances that might reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any
private party or governmental body or agency, against or affecting the Company or any of its subsidiaries relating to Hazardous Materials or any Environmental Laws. 

(gg) Periodic Review of Costs of Environmental Compliance. In the ordinary course of its business,
the Company conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities
(including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any
potential liabilities to third parties). On the basis of such review and the amount of its established reserves, the Company has reasonably concluded that such associated costs and liabilities would not, individually or in the aggregate, result in a
Material Adverse Change. 
 (hh) ERISA Compliance. The Company and its subsidiaries and
any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or
maintained by the Company, its subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance with ERISA, except for such non-compliance as would not be reasonably expected to cause a Material Adverse Change.
“ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group of organizations described in Sections 414(b),(c),(m) or (o) of the Internal Revenue Code of 1986, as amended, and the
regulations and published interpretations thereunder (the “Code”) of which the Company or such subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur
with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its
subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, 

  
 10 

 
would have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or
reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each
“employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred,
whether by action or failure to act, which would cause the loss of such qualification. 
 (ii)
Brokers. Except for the sales agency discounts and commissions payable to the Agent as described in the Time of Sale Prospectus and the Prospectus, there is no broker, finder or other party that is entitled to receive from the Company any
brokerage or finder’s fee or other fee or commission as a result of any transactions contemplated by this Agreement. 
 (jj) Foreign Corrupt Practices Act. Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee, affiliate or other person acting on
behalf of the Company or any of its subsidiaries is aware of or has taken any action, directly or indirectly, that has resulted or would result in a violation of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations
thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of
any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate
for foreign political office, in contravention of the FCPA; and the Company and its subsidiaries and, to the knowledge of the Company, the Company’s affiliates have conducted their respective businesses in compliance with the FCPA and have
instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith. 

(kk) Money Laundering Laws. The operations of the Company and its subsidiaries are, and have been
conducted at all times, in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all applicable jurisdictions, the
rules and regulations thereunder and any related or similar applicable rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or
proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Company, threatened.

 (ll) OFAC. Neither the Company nor any of its subsidiaries nor, to the knowledge of
the Company, any director, officer, agent, employee, affiliate or person acting on behalf of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury
Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or
entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC. 
 Any officers’ certificate delivered by the Company pursuant to Section 8(f)(ii) shall be deemed a representation and warranty by the Company to the Agent as to the matters covered
thereby. 

  
 11 

 The Company acknowledges that the Agent and, for purposes of the opinions to
be delivered pursuant to Section 8 hereof, counsel to the Company and counsel to the Agent, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consents to such reliance. 

Section 2. Sale and Delivery of the Shares. 

On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions
herein set forth, the Company and the Agent agree that the Company may from time to time seek to sell Shares through the Agent, acting as sales agent as follows: 

(a) The Company may submit its orders to the Agent by telephone or email (or other method mutually agreed
upon by the parties) (including any price, time or size limits or other customary parameters or conditions) (a “Sales Notice”) to sell Shares on any Trading Day (as defined herein) which order shall be confirmed by the Agent (and
accepted by the Company) by electronic mail using a form substantially similar to that attached hereto as Exhibit A. As used herein, “Trading Day” shall mean any trading day on the NYSE, other than a day on which the
NYSE is scheduled to close prior to its regular weekday closing time. Each Sales Notice shall be effective until (i) the Shares specified in such Sales Notice have been sold, (ii) the Company suspends or terminates such Sales Notice or
(iii) this Agreement terminates for any reason. 
 (b) Subject to the terms and conditions
hereof, the Agent shall use its commercially reasonable efforts consistent with its normal trading and sales practices to execute any Company order to sell Shares submitted to it hereunder and with respect to which the Agent has agreed to act as
sales agent. The Agent may sell Shares by any method permitted by law deemed to be an “at-the-market” offering as defined in Rule 415 of the Securities Act, including, without limitation, sales made directly on the NYSE, on any other
existing trading market for the Shares or to or through a market maker. The Company acknowledges and agrees that (i) there can be no assurance that the Agent will be successful in selling the Shares, (ii) the Agent will incur no liability
or obligation to the Company or any other person or entity if it does not sell Shares for any reason except as a result of an act or failure to act undertaken or omitted to be taken by the Agent through its gross negligence or willful misconduct,
and (iii) the Agent shall be under no obligation to purchase Shares on a principal basis pursuant to this Agreement. 
 (c) The Agent hereby covenants and agrees not to make any sales of the Shares on behalf of the Company other than as permitted by the terms of this Agreement and in compliance with the applicable Sales
Notice. 
 (d) The Company shall not authorize the issuance and sale of, and the Agent shall not
sell, any Share at a price lower than the minimum price therefor designated by the Company pursuant to Section 2(a) above and in the applicable Sales Notice. In addition, the Company or the Agent may, upon notice to the other party
hereto by telephone (confirmed promptly by email or facsimile), suspend an offering of the Shares pursuant to this Agreement; provided, however, that such suspension or termination shall not affect or impair the parties’ respective
obligations with respect to the Shares sold hereunder prior to the receipt of such notice. 

(e) The Agent shall provide written confirmation (which may be by facsimile or email) to the Company
following the close of trading on the NYSE each day in which Shares are sold under this Agreement setting forth (i) the amount of Shares sold on such day, (ii) the gross offering proceeds received from such sale and (iii) the
commission payable by the Company to the Agent with respect to such sales. 

  
 12 

 (f) At each Time of Sale, Settlement Date and Representation
Date (as defined below), the Company shall be deemed to have affirmed each representation and warranty contained in this Agreement. Any obligation of the Agent to use its commercially reasonable efforts to sell the Shares on behalf of the Company as
sales agent shall be subject to the continuing accuracy of the representations and warranties of the Company herein, to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the additional conditions
specified in Section 8 of this Agreement. 
 (g) Notwithstanding any other provision
of this Agreement, the Company and the Agent agree that no sales of Shares shall take place, the Company shall not request the sales of any Shares that would be sold and the Agent shall not be obligated to sell or offer to sell, during any period in
which the Company’s insider trading policy, a copy of which has been provided to the Agent, as it exists on the date of this Agreement and including any amendments or supplements made thereto from time to time, copies of which shall be provided
to the Agent, regardless of whether still in effect, would prohibit the purchase or sale of common stock of the Company by persons subject to such policy, or during any other period in which the Company is in possession of material non-public
information. 
 (h) While under the law of The Netherlands and the Company’s Articles of
Association the Common Stock may be issued with a preemptive right to subscribe to an issue of Common Stock, pursuant to rights granted by the Company by its shareholders to issue Common Stock without such preemptive right, all Shares issued
pursuant to this Agreement shall be issued excluding any preemptive rights. 
 Section 3. Fees.

 The fee payable to the Agent for sales of the Shares with respect to which the Agent acts as sales agent
hereunder shall be equal to 1.85% of the gross offering proceeds of such Shares and deducted from the gross proceeds of any sales of such Shares prior to payment to the Company of the net proceeds from the sale of such Shares. 

Section 4. Payment, Delivery and Other Obligations. 

Settlement for sales of the Shares pursuant to this Agreement will occur on the third Trading Day (or such earlier day as
is industry practice for regular-way trading) following the date on which such sales are made (each such day, a “Settlement Date”). On or prior to each Settlement Date, the Shares sold through the Agent for settlement on such date
shall be issued and delivered by the Company to an account designated by the Agent at The Depository Trust Company or by such other means of delivery as may be mutually agreed upon by the parties thereto. On or prior to each Settlement Date, the
Agent will deliver the net proceeds from the sale of such Shares to an account designated by the Company. Settlement for all such Shares shall be effected by free delivery of the Shares by the Company or its transfer agent to the Agent’s
account or its designee’s account (provided that the Agent shall have given the Company written notice of such designee prior to the Settlement Date) at The Depository Trust Company or by such other means of delivery as may be mutually
agreed upon by the parties hereto, which in all cases shall be freely tradable, transferable, registered shares in good deliverable form, in return for payment in same day funds delivered to the account designated by the Company. If the Company, or
its transfer agent (if applicable), shall default on its obligation to deliver the Shares on any Settlement Date, the Company shall (i) hold the Agent harmless against any loss, claim, damage, or expense (including reasonable legal fees and
expenses), as incurred, arising out of or in connection with such default by the Company and (ii) pay the Agent any commission, discount or other compensation to which it would otherwise be entitled absent such default. 

  
 13 

 Section 5. Additional Covenants. 

The Company further covenants and agrees with the Agent as follows: 

(a) Commission Filing Fees. The Company agrees to pay the required Commission filing fees relating
to the Shares within the time required by Rule 456(b)(1) under the Securities Act and otherwise in accordance with the Rules 456(b) and 457(r) under the Securities Act. 

(b) Delivery of Registration Statement, Time of Sale Prospectus and Prospectus. The Company
shall furnish to you, without charge, copies of the Registration Statement, any amendments thereto and shall furnish to you in New York City, without charge, (i) prior to 10:00 a.m. New York City time on the business day next succeeding the
date of this Agreement and (ii) as soon as practicable during the period mentioned in Section 5(g) or 5(h) below, as many copies of the Time of Sale Prospectus, the Prospectus and any supplements and amendments thereto or to
the Registration Statement as you may reasonably request; provided, that the Company shall not be required to furnish any document incorporated into the Prospectus or the Time of Sale Prospectus to the extent such document is available on
EDGAR. In case the Agent is required to deliver, under the Securities Act (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule), a prospectus relating to the Shares after the nine-month period referred
to in Section 10(a)(3) of the Securities Act, or after the time a post-effective amendment to the Registration Statement is required pursuant to Item 512(a) of Regulation S-K under the Securities Act, upon the request of the Agent, and at
its own expense, the Company shall prepare and deliver to the Agent as many copies as the Agent may reasonably request of an amended Registration Statement or amended or supplemented prospectus complying with Item 512(a) of Regulation S-K or
Section 10(a)(3) of the Securities Act, as the case may be; provided, that the Company shall not be required to furnish any document incorporated into Registration Statement, the Prospectus or the Time of Sale Prospectus to the extent
such document is available on EDGAR. 
 (c) Agent’s Review of Proposed Amendments and
Supplements. Prior to amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus (other than any amendment or supplement through incorporation by reference of any report filed under the Exchange
Act), the Company shall furnish to the Agent for review, a reasonable amount of time prior to the proposed time of filing or use thereof, a copy of each such proposed amendment or supplement, and will file with the Commission within the applicable
period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such Rule. If the Agent objects thereto, the Agent may cease making sales of Shares pursuant to this Agreement. 

(d) Free Writing Prospectuses. The Company shall furnish to the Agent for review, a
reasonable amount of time prior to the proposed time of filing or use thereof, a copy of each proposed free writing prospectus or any amendment or supplement thereto to be prepared by or on behalf of, used by, or referred to by the Company and the
Company shall not file, use or refer to any proposed free writing prospectus or any amendment or supplement thereto without the Agent’s consent, such consent not to be unreasonably withheld or delayed. The Company shall furnish to the Agent,
without charge, as many copies of any free writing prospectus prepared by or on behalf of, or used by the Company, as the Agent may reasonably request. If at any time when a prospectus is required by the Securities Act (including, without
limitation, pursuant to Rule 173(d)) to be delivered in connection with sales of the Shares (but in any event if at any time during the Delivery Period) there occurred or occurs an event or development as a result of which any free writing
prospectus prepared by or on behalf of, used by, or referred to by the Company conflicted or would conflict with the information contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted
or would omit to state a material fact necessary in order to make the 

  
 14 

 
statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company shall promptly amend or supplement such free writing prospectus to eliminate
or correct such conflict or so that the statements in such free writing prospectus as so amended or supplemented will not include 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 prevailing at such subsequent time, not misleading, as the case may be; provided, however, that prior to amending or supplementing any such free writing prospectus, the Company shall furnish
to the Agent for review, a reasonable amount of time prior to the proposed time of filing or use thereof, a copy of such proposed amended or supplemented free writing prospectus. If the Agent objects thereto, the Agent may cease making sales of
Shares pursuant to this Agreement. 
 (e) Filing of Agent Free Writing Prospectuses.
The Company shall not take any action that would result in the Agent or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Agent that
the Agent otherwise would not have been required to file thereunder. 
 (f) Amendments and
Supplements to Time of Sale Prospectus. If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as
a result of which it is necessary to amend or supplement the Time of Sale Prospectus so that the Time of Sale Prospectus does not include 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 when delivered to a prospective purchaser, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts in any material respect with
the information contained in the Registration Statement, or if, in the opinion of counsel for the Agent, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, including the Securities Act, the
Company shall (subject to Sections 5(c) and 5(d)) forthwith prepare, file with the Commission and furnish, at its own expense, to the Agent and to any dealer upon request, either amendments or supplements to the Time of Sale
Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not include 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 when delivered to a prospective purchaser, not misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict in any material respect with the Registration Statement, or so that the Time
of Sale Prospectus, as amended or supplemented, will comply with applicable law including the Securities Act (provided that the only remedy the Agent shall have with respect to the failure by the Company to make any such filing, other than as set
forth in Section 11 hereof, shall be to cease making sales of Shares pursuant to this Agreement). Until such time as the Company makes the relevant filing described above, the Agent may cease making sales of Shares pursuant to this
Agreement. 
 (g) Securities Act Compliance. After the date of this Agreement and during
the Delivery Period, the Company shall promptly advise the Agent in writing (i) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (ii) of the time and date of any filing of any
post-effective amendment to the Registration Statement or any amendment or supplement to the Time of Sale Prospectus, any free writing prospectus or the Prospectus, (iii) of the time and date that any post-effective amendment to the
Registration Statement becomes effective and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or any amendment or supplement to the Time
of Sale Prospectus or the Prospectus or of any order preventing or suspending the use of the Time of Sale Prospectus, any free writing prospectus or the Prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the
Shares from any securities exchange upon 

  
 15 

 
which they are listed for trading or included or designated for quotation, or of the threatening or initiation of any proceedings for any of such purposes. Until such time as any stop order is
lifted, the Agent may cease making Sales under this Agreement. Additionally, the Company agrees that it shall comply with the provisions of Rule 424(b), Rule 433 and Rule 430A, as applicable, under the Securities Act and will use its reasonable
efforts to confirm that any filings made by the Company under such Rule 424(b) or Rule 433 were received in a timely manner by the Commission. If, after the date of this Agreement, the Company receives notice pursuant to Rule 401(g)(2) under the
Securities Act from the Commission or otherwise ceases to be eligible to use the automatic shelf registration form, the Company shall promptly advise the Agent in writing of such notice or ineligibility. 

(h) Amendments and Supplements to the Prospectus and Other Securities Act Matters. If any
event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus so that the Prospectus, as then amended or supplemented, does not include 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 when the Prospectus is delivered to a purchaser, not misleading, or if in the opinion of the Agent or counsel for the Agent it is otherwise necessary
to amend or supplement the Prospectus to comply with applicable law, including the Securities Act, the Company agrees (subject to Section 5(c) and 5(d)) to promptly prepare, file with the Commission and furnish at its own expense
to the Agent and to dealers, amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not include 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 when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law including the Securities
Act (provided that the only remedy the Agent shall have with respect to the failure by the Company to make any such filing, other than as set forth in Section 11 hereof, shall be to cease making sales of Shares pursuant to this
Agreement). Neither the Agent’s consent to, or delivery of, any such amendment or supplement shall constitute a waiver of any of the Company’s obligations under Sections 5(c) or 5(d). In addition, the Company agrees to file
on or before their respective due dates all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the
date of the Prospectus and for the duration of the Delivery Period. For the duration of the Delivery Period, the Company agrees (i) to include in its quarterly reports on Form 10-Q, and its annual reports on 10-K, a summary detailing, for the
relevant reporting period, (1) the number of Shares sold through the Agent pursuant to this Agreement, (2) the net proceeds received by the Company from such sales and (3) the compensation paid by the Company to the Agent with respect
to such sales or alternatively, (ii) to prepare a prospectus supplement or in such other filing permitted by the Securities Act or Exchange Act (each an “Interim Prospectus Supplement”) with such summary information and, at
least once a quarter and subject this Section 5, file such Interim Prospectus Supplement pursuant to Rule 424(b) under the Securities Act (and within the time periods required by Rule 424(b) and Rules 430A, 430B or 430C under the
Securities Act)). 
 (i) Blue Sky Compliance. The Company shall cooperate with the Agent
and counsel for the Agent to qualify or register the Shares for sale under (or obtain exemptions from the application of) the state securities or blue sky laws or the provincial securities laws of Canada of those jurisdictions designated by the
Agent, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Shares, provided that in the opinion of the Agent’s counsel, such qualification or
registration is required for the issuance, sale and delivery of the Shares. The Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction
where it is not presently qualified or where it would be subject to taxation as a foreign 

  
 16 

 
corporation. The Company will advise the Agent promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Shares for offering, sale or trading in
any jurisdiction or any initiation or threat of any proceeding for any such purpose. 
 (j)
Use of Proceeds. The Company shall apply the net proceeds from the sale of the Shares sold by it in the manner described under the caption “Use of Proceeds” in each Applicable Prospectus. 

(k) Transfer Agent. The Company shall engage and maintain, at its expense, a registrar and
transfer agent for the Shares. 
 (l) Earnings Statement. As soon as practicable, but in
any event no later than fifteen months after the date of this Agreement, the Company will make generally available to its security holders and to the Agent an earnings statement (which need not be audited) covering a period of at least twelve months
beginning with the first fiscal quarter of the Company occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder. Agent
acknowledges and agrees that the Company’s normal periodic filings pursuant to the Securities Exchange Act of 1934 will satisfy this obligation. 

(m) Periodic Reporting Obligations. The Company shall file, on a timely basis, with the Commission
and the NYSE all reports and documents required to be filed under the Exchange Act. 
 (n)
Exchange Act Compliance. During the Delivery Period, the Company shall file all documents required to be filed with the Commission pursuant to Section 13, 14 or 15 of the Exchange Act in the manner and within the time periods required by
the Exchange Act. 
 (o) Listing. The Company will use its commercially reasonable best
efforts to maintain the listing of the Shares on the NYSE during the term of this Agreement. 

(p) Company to Provide Copy of the Prospectus in Form That May be Downloaded from the Internet.
The Company shall cause to be prepared and delivered, at its expense, on or before the date of the initial Sales Notice under this Agreement, to the Agent an “electronic Prospectus” to be used by the Agent in connection with the
offering and sale of the Shares. As used herein, the term “electronic Prospectus” means a form of Time of Sale Prospectus, and any amendment or supplement thereto (excluding any documents incorporated by reference therein), that
meets each of the following conditions: (i) it shall be encoded in an electronic format, satisfactory to the Agent, that may be transmitted electronically by the Agent to offerees and purchasers of the Shares; and (ii) it shall disclose
the same information as the paper Time of Sale Prospectus, except to the extent that graphic and image material cannot be disseminated electronically, in which case such graphic and image material shall be replaced in the electronic Prospectus with
a fair and accurate narrative description or tabular representation of such material, as appropriate. The Company hereby confirms that it has included or will include in the Prospectus filed pursuant to EDGAR or otherwise with the Commission an
undertaking that, upon receipt of a request by an investor or his or her representative, the Company shall transmit or cause to be transmitted promptly, without charge, a paper copy of the Time of Sale Prospectus. 

(q) Agreement Not to Offer or Sell Additional Shares. During the period commencing on and
including the date hereof and ending on and including the earlier to occur of (x) the sale of all Shares being offered pursuant to this Agreement and (y) the termination of this Agreement (as the same may be extended as described below,
the “Lock-up Period”), the Company will not, without the prior written consent of the Agent (which consent may be withheld at the sole discretion of the Agent), sell or otherwise dispose of any shares of its Common Stock (other than
the Shares) or securities 

  
 17 

 
convertible into or exchangeable for the Company’s Common Stock, warrants or any rights to purchase or acquire, Common Stock during the period commencing on the Trading Day immediately prior
to the date on which any Sales Notice is delivered to the Agent hereunder and ending on the fifth Trading Day immediately following the final Settlement Date with respect to Shares sold pursuant to such Sales Notice (or, if the Sales Notice is
terminated or suspended prior to the sale of the Shares covered by a Sales Notice, the date of such suspension or termination); and will not directly or indirectly in any other “at-the-market” or continuous equity transaction offer to
sell, sell, contract to sell, grant any option to sell or otherwise dispose of any shares of Common Stock (other than the Shares) or securities convertible into or exchangeable for Common Stock, warrants or any rights to purchase or acquire, Common
Stock; provided, however, that the Company may (i) issue Common Stock or options to Common Stock, or issue Common Stock upon exercise of options, pursuant to any stock option, stock bonus, stock ownership, dividend reinvestment
plan or other stock plan or arrangement, benefits plan or other employee or director plan of the Company whether now in effect or hereafter implemented; (ii) issue securities upon exercise or conversion of any of the Company’s outstanding
securities or rights outstanding on the date hereof; (iii) file a registration statement on Form S-8 relating to employee or director stock or benefit plans and (iv) the issue of Common Stock or securities convertible into or exercisable
or exchangeable for Common Stock in connection with strategic transactions involving the Company and other entities, including without limitation, joint venture, licensing, collaboration, manufacturing, development, marketing, co-promotion or
distribution arrangements. Notwithstanding the foregoing, if (i) during the last 17 days of the Lock-up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs or (ii) prior to the
expiration of the Lock-up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-up Period, then in each case the Lock-up Period will be extended until the expiration of the
18-day period beginning on the date of the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless the Agent waives, in writing, such extension (which waiver may be withheld at the sole
discretion of the Agent), except that such extension will not apply if, (i) within three business days prior to the 15th calendar day before the last day of the Lock-up Period, the Company delivers a certificate, signed by the Chief Financial
Officer or Chief Executive Officer of the Company, certifying on behalf of the Company that (i) the Shares are “actively traded securities” (as defined in Regulation M), (ii) the Company meets the applicable requirements of
paragraph (a)(1) of Rule 139 under the Securities Act in the manner contemplated by FINRA Conduct Rule 2711(f)(4), and (iii) the provisions of FINRA Conduct Rule 2711(f)(4) are not applicable to any research reports relating
to the Company published or distributed by the Agent during the 15 days before or after the last day of the Lock-up Period (before giving effect to such extension). The Company will provide the Agent with prior notice of any such announcement that
gives rise to an extension of the Lock-up Period. 
 (r) Investment Limitation. The
Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the Company or any of its subsidiaries to register as an investment company under the Investment Company
Act. 
 (s) No Stabilization or Manipulation; Compliance with Regulation M. The Company
will not take, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of the Common Stock or any other reference security, whether to facilitate the sale
or resale of the Shares or otherwise, and the Company will, and shall cause each of its affiliates to, comply with all applicable provisions of Regulation M. If the limitations of Rule 102 of Regulation M (“Rule 102”) do not apply
with respect to the Shares or any other reference security pursuant to any exception set forth in Section (d) of Rule 102, then promptly upon notice from the Agent (or, if later, at the time stated in the notice), the Company will, and shall
cause each of its affiliates to, comply with Rule 102 as though such exception were not available but the other provisions of Rule 102 (as interpreted by the Commission) did apply.

Section 9. [Reserved]. 

Section 10. Effectiveness of this Agreement. This Agreement shall become effective upon the execution and delivery

 Section 11. Indemnification. 

(a) Indemnification of the Agent. The Company agrees to indemnify and hold harmless the Agent, its
directors, officers, employees and agents, and each person, if any, who controls the Agent within the meaning of the Securities Act or the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which the Agent or such
officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act, other federal or state statutory law or regulation, or the laws or regulations of foreign jurisdictions where Shares have been offered or sold or
at common law or otherwise (including in settlement of any litigation), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of 

  
 23 

 
or is based upon (A) (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information
deemed to be a part thereof pursuant to Rule 430A under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or
(ii) any untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Prospectus, any free writing prospectus that the Company has used, referred to or filed, or is required to file, pursuant to Rule 433(d) of
the Securities Act or the Prospectus (or any amendment or supplement thereto), 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; or (iii) any breach of the representations, warranties or covenants of the Company contained herein; or (B) the violation of any laws or regulations of foreign jurisdictions where Shares have been offered or
sold; and to reimburse the Agent and each such director, officer, employee or agent and controlling person for any and all expenses (including the fees and disbursements of counsel chosen by the Agent) as such expenses are reasonably incurred by the
Agent or such officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing
indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with written information furnished to the Company by the Agent expressly for use in the Registration Statement, the Time of Sale Prospectus, any such free writing prospectus or the Prospectus (or any amendment or
supplement thereto), it being understood and agreed that the only such information furnished by the Agent to the Company consists of the information described in subsection (b) below. The indemnity agreement set forth in this
Section 11(a) shall be in addition to any liabilities that the Company may otherwise have. 
 (b) Indemnification of the Company, its Directors and Officers. The Agent agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration
Statement and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, or any such director, officer or
controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with
the written consent of the Agent), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement, the Time of Sale Prospectus, any free writing prospectus that the Company has used, referred to or filed, or is required to file, pursuant to Rule 433(d) of the Securities Act or the Prospectus (or such
amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Time of Sale Prospectus, such free writing prospectus that the Company has used,
referred to or filed, or is required to file, pursuant to Rule 433(d) of the Securities Act, the Prospectus (or such amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Agent
expressly for use therein; and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense (including the fees and disbursements of counsel chosen by the Company reasonably acceptable to the Agent)
reasonably incurred by the Company, or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company hereby
acknowledges that the only information that the Agent has 

  
 24 

 
furnished to the Company expressly for use in the Registration Statement, the Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to
Rule 433(d) of the Securities Act or the Prospectus (or any amendment or supplement thereto) are the statements set forth in (i) the fourth paragraph on the front cover page of the Prospectus Supplement dated July 21, 2011 concerning the
terms of the offering of the Shares and (ii) the statements concerning the Agent contained in the first, second and third paragraphs under the heading “Plan of Distribution” of the Prospectus Supplement. The indemnity agreement set
forth in this Section 11(b) shall be in addition to any liabilities that the Agent may otherwise have. 
 (c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 11 of notice of the commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 11, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying
party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this Section 11 or to the extent it is not prejudiced as a proximate result
of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent
that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with
counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded
that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the
indemnifying party will not be liable to such indemnified party under this Section 11 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified
party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the fees and expenses of more than one separate counsel (together
with local counsel), representing the indemnified parties who are parties to such action), which counsel (together with any local counsel) for the indemnified parties shall be selected by the Agent (in the case of counsel for the indemnified parties
referred to in Section 11(a) above) or by the Company (in the case of counsel for the indemnified parties referred to in Section 11(b) above) (ii) the indemnifying party shall not have employed counsel satisfactory to
the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the
expense of the indemnifying party, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party and shall be paid as they are incurred. 

(d) Settlements. The indemnifying party under this Section 11 shall not be liable for
any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim,
damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an 

  
 25 

 
indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 11(c) hereof, the indemnifying party agrees that it shall be liable
for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party
shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or
consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is a party and indemnity was sought hereunder by such indemnified party, unless (A) there is no finding or
admission of any violation of legal requirements or any violation of the rights of any person or entity by the indemnified party and (B) the sole relief provided is monetary damages that are paid in full by the indemnifying party. 

Section 12. Contribution. If the indemnification provided for in Section 11 is applicable to but
otherwise for any reason held to be unavailable to and required or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party
shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company, on the one hand, and the Agent, on the other hand, from the offering of the Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) above 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 the Agent, on the other hand, in connection with the statements
or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Agent, on the other hand, in
connection with the offering of the Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Shares pursuant to this Agreement (before deducting expenses) received
by the Company, and the total fees received by the Agent, in each case as set forth on the front cover page of the Prospectus Supplement, bear to the aggregate initial public offering price of the Shares as set forth on such cover. The relative
fault of the Company, on the one hand, and the Agent, 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, on the one hand, or the Agent, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

 The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include, subject to the limitations set forth in Section 11(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.
The provisions set forth in Section 11(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 12; provided, however, that no additional notice
shall be required with respect to any action for which notice has been given under Section 11(c) for purposes of indemnification. 
 The Company and the Agent agree that it would not be just and equitable if contribution pursuant to this Section 12 were determined by pro rata allocation or by any other method of allocation
which does not take account of the equitable considerations referred to in this Section 12. 

Notwithstanding the provisions of this Section 12, the Agent shall not be required to contribute any amount
in excess of the total fees received by the Agent in connection with the sale of the Shares. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act)

  
 26 

 
shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 12, each officer and employee of the Agent and
each person, if any, who controls the Agent within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Agent, and each director of the Company, each officer of the Company who signed the
Registration Statement, and each person, if any, who controls the Company with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company. 

Section 13. Termination of this Agreement. (a) The Company shall have the right, by giving written notice as
hereinafter specified, to terminate this Agreement in its sole discretion at any time. Any such termination shall be without liability of any party to any other party and shall terminate each party’s obligations hereunder, except that
(i) with respect to any pending sale through the Agent for the Company, the obligations of the Company, including, but not limited to, its obligations under Section 4 above, shall remain in full force and effect notwithstanding such
termination; and (ii) the provisions of Section 1 (with respect to sales of Shares made prior to the date of termination), Section 3 (with respect to fees payable to Agent for sales of Shares made prior to the date of
termination), Section 4 (with respect to sales of Shares made prior to the date of termination), Section 6, Section 11 and Section 12 of this Agreement shall remain in full force and effect notwithstanding
such termination. 
 (b) The Agent shall have the right, by giving written notice as hereinafter
specified, to terminate this Agreement in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) with respect to any pending sale through the Agent for the Company, the
obligations of the Company, including, but not limited to, its obligations under Section 4 above, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Section 1,
Section 3, Section 4, Section 6, Section 9, Section 11 and Section 12 of this Agreement shall remain in full force and effect notwithstanding such termination. 

(c) This Agreement shall remain in full force and effect until and unless terminated pursuant to
Section 13(a) or (b) above or otherwise by mutual agreement of the parties, and shall automatically terminate upon the earlier of (i) July 28, 2012 and (ii) such time as all Shares contemplated to be sold in
connection herewith have been sold; provided, that any such termination by mutual agreement or automatically pursuant to this clause (c) shall in all cases be deemed to provide that Section 1,
Section 3, Section 4, Section 6, Section 11 and Section 12 of this Agreement shall remain in full force and effect. 

(d) Any termination of this Agreement shall be effective on the date specified in such notice of
termination or upon the consummation of the final sale of Shares; provided, that such termination shall not be effective until the close of business on the date of receipt of such notice by the Agent or the Company, as the case may be,
in the case of any termination pursuant to Section 13(a) or (b). If such termination shall occur prior to the Settlement Date for any sale of Shares, such sale shall settle in accordance with the provisions of
Section 4. 
 Section 14. No Advisory or Fiduciary Relationship. The Company acknowledges and

Section 19. Governing Law Provisions. This Agreement shall be governed by and construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be performed entirely in such state. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby
(“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the Borough of Manhattan in the City of New York or the courts of the State of New York in each case located in the Borough
of Manhattan in the City of New York (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 (a “Related Judgment”), 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. Each party not located
in the United States irrevocably appoints CT Corporation System, which currently maintains a New York City office at 111 Eighth Avenue, 13th Floor, New York, NY 10011, United States of America, as its agent to receive service of process or other
legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the Borough of Manhattan in the City of New York. 

With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law,
all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any
Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or
Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended. 
 Section 20. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements,
understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the
same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.
The Table of Contents and the Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification provisions of Section 11 and the contribution provisions of Section 12,
and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of Section 11 and Section 12 hereto fairly allocate the risks in light of the ability of the parties to
investigate the Company, its affairs and its business in order to assure that adequate disclosure has been made in the Registration Statement, the Time of Sale Prospectus, each free writing prospectus and the Prospectus (and any amendments and
supplements thereto), as required by the Securities Act and the Exchange Act.

 SCHEDULE II 
 Due Diligence Protocol 
 Set forth below are guidelines for
use by the Company and the Agent in connection with the Agent’s continuous due diligence efforts in connection with the sale and distribution of the Shares pursuant to the Agreement. For the avoidance of doubt, the Agent and the Company expect
that no sales under the Agreement will be requested or made at any time the Company is, or could be deemed to be, in possession of material non-public information with respect to the Company. 

 

	 	1.	 On or immediately prior to each Representation Date, in addition to the documents provided pursuant to Sections 5(t), (u),
(v) and (w) of the Agreement, the Agent expects to conduct a due diligence call with the appropriate business, financial and legal representatives of the Company. 

 

	 	2.	 On the date of or promptly after the filing of the Company’s quarterly reports on Form 10-Q, the Agent expects to conduct a due diligence call
with the appropriate business, financial, accounting and legal representatives of the Company and that the Company shall provide the certificate referred to in Section 8(f) of the Agreement. 

 

	 	3.	 In the event that the Company requests the Agent to sell on any one Trading Day an amount of Shares that would be equal to or greater than 25% of
the average daily trading volume (calculated based on the most recent three completed Trading Days) of the Common Shares, the Agent expects to conduct a due diligence call with the appropriate business, financial, accounting and legal
representatives of the Company and that the Company may be asked provide the certificate referred to in Section 8(f) of the Agreement. 

  

	 	4.	 The Company shall provide all information that the Agent may reasonably request from time to time in connection with its due diligence review;
provided that neither the Company nor its advisors, counsel or independent accountants shall be required to so comply to the extent that such compliance would violate any confidentiality agreement or impair or waive any legal privilege of the
Company. 

 The foregoing is an expression of current intent only, and shall not in any manner
limit the Agent’s rights under the Agreement, including the Agent’s right to require such additional due diligence procedures as the Agent may reasonably request pursuant to the Agreement.

 EXHIBIT B 
 Opinion of U.S. Counsel for the Company to be delivered pursuant to Section 8(d) 
 1. The Sales Agreement has been duly executed and delivered by the Company. 
 2. At the time of filing the Registration Statement, the Company was a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act. The Registration Statement is an
“automatic shelf registration statement,” as defined in Rule 405, that became effective on July 29, 2009. To our knowledge, the Company has not received from the Commission any notice pursuant to Rule 401(g)(2) under the Securities
Act objecting to the Company’s use of the automatic shelf registration form. To our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for such purpose
have been instituted or are pending or are contemplated or threatened by the Commission. 
 3.
Any required filing of the Prospectus and any supplement thereto pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the time period required by such Rule 424(b). 

4. The execution and delivery of the Sales Agreement by the Company, the performance by the Company of
its obligations thereunder (other than performance by the Company of its obligations under the indemnification provisions of the Sales Agreement, as to which we express no opinion) and the issuance and sale of the offered securities (a) will
not result in any violation of any federal, Texas or New York law or, to our knowledge, any federal administrative regulation or any decree or order of any court or governmental agency identified to us by the Company as material to it and listed on
Schedule I hereto, or (b) will not require any consents, approvals or authorizations to be obtained by the Company, or any registrations, declarations or filings to be made by the Company, in each case, under any federal, Texas or New York
statute, rule or regulation applicable to the Company that have not been obtained or made. 
 5.
The Company is not an “investment company” within the meaning of Investment Company Act. 
 6. Since January 1, 2009, each annual, periodic or current report filed by the Company pursuant to the Exchange Act (other than the financial statements and supporting schedules included therein, as
to which no opinion need be rendered) and incorporated or deemed to be incorporated by reference in the Prospectus complied when so filed as to form in all material respects with the Exchange Act. 

7. The Registration Statement and the Prospectus filed by the Company pursuant to the Securities Act
(other than documents incorporated by reference) complied when so filed as to form in all material respects with the Securities Act. 
 Although we have not undertaken, except as otherwise indicated in our opinion, to determine independently, and do not assume any responsibility for, the accuracy or completeness of the statements in the
Registration Statement and the Prospectus, we have reviewed and are familiar with the Registration Statement and the Prospectus and have participated in conferences with officers and other representatives of the Company, at which the contents of the
Registration Statement and the Prospectus and related matters were discussed, and no facts have come to our attention that lead us to believe that: 

(A) the Registration Statement (other than the financial statements and the notes thereto and the
schedules and other financial data included therein, as to which we express no opinion), as of the effective date contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make
the statements therein not misleading, or 
 (B) the Prospectus (other than the financial
statements and the notes thereto and the schedules and other financial data included therein, as to which we express no opinion), as of the date hereof, contained an untrue statement of a material fact or omitted 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. 
  

  
 B-1

 EXHIBIT C 
 Opinion of Dutch Counsel for the Company to be delivered pursuant to Section 8(d) 
 A. The Company has been duly incorporated and is validly existing as a limited liability company (naamloze vennootschap) under the laws of The Netherlands. 

B. The Company has the corporate power and corporate authority to (i) own, lease and operate its properties, and to
conduct the business of a holding company, in each case as specifically described in the Base Prospectus and the Supplemental Prospectus, (ii) to enter into the Agreement and (iii) to perform its contractual obligations under the
Agreement. 
 C. The authorized, issued and outstanding capital stock of the Company (including the Shares)
conforms in all material respects to the statements relating thereto set forth in the Base Prospectus and the Supplemental Prospectus. 
 D. No shareholder of the Company has, in respect of the issuance of the Shares, any pre-emptive right to subscribe for or purchase any of the Shares under the Company Articles or any provision of
Netherlands law applicable to companies generally. 
 E. The Shares have been duly authorized for issuance and
sale and, when issued and delivered by the Company pursuant to the Agreement against payment of the consideration set forth therein, the Shares will be validly issued, fully paid and non-assessable. 

F. Each of (i) the execution and delivery by the Company of the Agreement and the performance by the Company of its
contractual obligations thereunder and (ii) the issuance and sale by the Company of the Shares, have been duly authorized by all necessary corporate action on the part of the Company. The Agreement has been duly executed and delivered by the
Company. 
 G. Neither (i) the execution and delivery by the Company of the Agreement and the performance
by the Company of its contractual obligations thereunder nor (ii) the issuance and sale by the Company of the Shares, will result in the violation of any provision of (x) the Company Articles, (y) any published law, rule or regulation
of The Netherlands, or (z) any decree or order of any court or governmental agency of The Netherlands known to us. 
 H. Except for the fulfilment of information requirements pursuant to the Wet financiële betrekkingen buitenland and the rules and regulations promulgated pursuant thereto in respect of a payment or
receipt of a payment (the failure to comply with which will not impair the enforceability of the Agreement), neither (i) the execution and delivery by the Company of the Agreement and the performance by the Company of its contractual
obligations thereunder nor (ii) the issuance and sale by the Company of the Shares, will require any consents, approvals or authorizations of any national governmental or regulatory authority of The Netherlands to be obtained, or any
declarations or filings to be made by the Company with any national governmental or regulatory authority of The Netherlands, in each case under any statute, rule or regulation of The Netherlands. 
  

  
 C-1

 EXHIBIT D 
 Opinion of Chief Legal Officer the Company to be delivered pursuant to Section 8(d) 
 1. Each of the subsidiaries of the Company listed on Schedule A, attached hereto, (the “Specified Subsidiaries”) is a corporation, partnership or limited liability company, as applicable,
duly incorporated or organized, as applicable, and is validly existing and in good standing under the laws of the state of its incorporation or organization, as applicable. 

2. All of the issued and outstanding capital stock or other equity or ownership interests of each Specified Subsidiary

or through subsidiaries. 
 3. To my knowledge, there are no legal or governmental actions, suits or proceedings
pending or threatened which are required to be disclosed in the Registration Statement, other than those disclosed therein. 
 4. To my knowledge without independent investigation, the execution and delivery of the Sales Agreement by the Company, the performance by the Company of its obligations thereunder (other than performance
by the Company of its obligations under the indemnification section of the Sales Agreement, as to which I express no opinion) and the issuance and sale of the offered securities will not constitute a breach of, or Default under, or result in the
creation or imposition of any lien, charge or encumbrance upon any material property or assets of the Company or any of the Specified Subsidiaries pursuant to the terms of any material agreement filed as an exhibit to the Company’s Form 10-K
for the period ended December 31, 2010 or otherwise incorporated by reference into the Registration Statement. 

5. To my knowledge without independent investigation, neither the Company nor any of the Specified Subsidiaries is in
violation of its charter, bylaws, operating agreement or similar organizational document, as applicable, except for such violation or default as would not, individually or in the aggregate, result in a Material Adverse Change.
