The Underwriters shall have the right to exercise the Option to purchase pursuant to clause (iii) or clause (iv) below, as applicable, severally and not jointly, all or any portion of the Option Shares at the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Firm Shares but not payable on such Option Shares (such reduced price, the “Option Purchase Price”).

Any such Option Notice shall specify the aggregate number of Option Shares to be purchased by the Underwriters and the date and time when such Option Shares are to be delivered and paid for (each an “Option Closing Date”), which may be the same date and time as the First Closing Date (as hereinafter defined) but shall not be earlier than the First Closing Date nor later than five (5) full business days after the date of such notice. If the Option Notice is provided subsequent to the First Closing Date, such Option Closing Date must be at least two (2) business days after the written notice is given.

Upon the Company’s execution and delivery to the Forward Seller of any Additional Forward Sale Agreement, the Forward Purchaser shall promptly execute and deliver such Additional Forward Sale Agreement to the Company, and upon such execution and delivery to the Company, on the basis of the representations, warranties and agreements set forth herein, and subject to the conditions set forth herein, the Forward Seller (with respect to any Borrowed Option Shares) and the Company (with respect to any Company Top-Up Option Shares), severally and not jointly, hereby agrees to sell to the several Underwriters, and the Underwriters shall purchase from the Forward Seller, the number of Option Shares as set forth in the relevant Option Notice at the Option Purchase Price (with each such Underwriter purchasing the number of Option Shares (subject to adjustments to eliminate fractional shares as the Underwriters may determine) that bears the same proportion to the total number of Option Shares as the number of Borrowed Firm Shares set forth in the table on Schedule I opposite the name of such Underwriter bears to the total number of Borrowed Firm Shares on such Schedule).

(iv)    If the Company does not timely execute and deliver an Additional Forward Sale Agreement pursuant to clause (iii) above, then on the basis of the representations and warranties contained in this Agreement, and subject to the terms and conditions stated herein, the Company hereby agrees to sell to the

In addition, in the event that in the Forward Purchaser’s good faith and commercially reasonable judgment (A) the Forward Seller is unable to borrow and deliver for sale under this Agreement the number of shares of Common Stock equal to the number of Borrowed Firm Shares deliverable by the Forward Seller hereunder or (B) the Forward Seller would incur a Stock Loan Fee (as defined under the Forward Sale Agreement) of more than a rate equal to 200 basis points per annum to do so, then, in each case, the Forward Seller shall only be required to deliver for sale to the Underwriters on the First Closing Date the aggregate number of shares of Common Stock that the Forward Seller is able to so borrow at or below such Stock Loan Fee.

(c)    If the Company has entered into an Additional Forward Sale Agreement with the Forward Purchaser pursuant to Section 2(a)(iii) hereof, with respect to the related Borrowed Option Shares, if (i) any of the conditions to effectiveness of such Additional Forward Sale Agreement set forth therein are not satisfied on or prior to the relevant Option Closing Date, (ii) the Company has not performed all of the obligations required to be performed by it under this Agreement on or prior to such Option Closing Date or (iii) any of the conditions set forth in Section 7 hereof have not been satisfied on or prior to such Option Closing Date (clauses (i) through (iii) of this Section 2(c), together, the “Option Conditions”), then the Forward Seller, in its sole discretion, may elect not to borrow and deliver for sale to the Underwriters the Borrowed Option Shares otherwise deliverable by the Forward Seller hereunder. In addition, in the event that in the Forward Purchaser’s good faith and commercially reasonable judgment (A) the Forward Seller is unable to borrow and deliver for sale under this Agreement the number of shares of Common Stock equal to the number of Borrowed Option Shares deliverable by the Forward Seller hereunder or (B) the Forward Seller would incur a Stock Loan Fee (as defined under such Additional Forward Sale Agreement) of more than a rate equal to 200 basis points per annum to do so, then, in each case, the Forward Seller shall only be required to deliver for sale to the Underwriters on such Option Closing Date the aggregate number of shares of Common Stock that the Forward Seller is able to so borrow at or below such Stock Loan Fee.

(d)    If (i) the Forward Seller elects pursuant to Section 2(b) hereof not to borrow and deliver for sale to the Underwriters on the First Closing Date the total number of Borrowed Firm Shares otherwise deliverable by it hereunder, or (ii) the Forward Purchaser has entered into an Additional Forward Sale Agreement with the Company pursuant to Section 2(a)(iii) hereof and the Forward Seller elects pursuant to Section 2(c) hereof not to borrow and deliver for sale to the Underwriters on the relevant Option Closing Date the total number of Borrowed Option Shares otherwise deliverable by it hereunder in respect of such Option Closing Date, then the Forward Seller will use its commercially reasonable efforts to notify the Company no later than 5:00 p.m., New York City time, on the first business day prior to the First Closing Date or such Option Closing Date, as the case may be.

(e)    The Company acknowledges and agrees that the Underwriters, the Forward Purchaser and the Forward Seller are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of the Shares contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, none of the Underwriters, the Forward Seller or the Forward Purchaser is advising the Company or any other person as to any legal, tax, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and none of the Underwriters, the Forward Purchaser or the Forward Seller shall have any responsibility or liability to the Company with respect thereto. Any review by the Underwriters, the Forward Purchaser or the Forward Seller of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters, the Forward Purchaser or the Forward Seller, as the case may be, and shall not be on behalf of the Company.

(“DTC”) to credit the Shares to the account of the Underwriters at DTC. The Shares will be registered in the name of Cede & Co., as nominee of DTC and will be made available to the Underwriters for checking in New York, New York, not later than 2:00 p.m., New York City time, on the business day preceding the relevant Closing Date.

4.    Agreements of the Company. The Company agrees with the Underwriters, the Forward Purchaser and the Forward Seller that:

(a)    The Company will cause the Prospectus, in a form approved by the Underwriters, to be filed pursuant to Rule 424(b) under the Act and will notify the Underwriters promptly of such filing. During the period for which a prospectus relating to the Shares is required to be delivered under the Act (whether physically or through compliance with Rule 172 under the Act or any similar rule), the Company will promptly advise the Underwriters, the Forward Seller and the Forward Purchaser (i) when any amendment to the Registration Statement has been filed or shall have become effective, (ii) when any subsequent supplement to the Prospectus (including documents deemed to be incorporated by reference into the Prospectus) has been filed and shall furnish the Underwriters, the Forward Seller and the Forward Purchaser with copies thereof, (iii) of any request by the Commission for any amendment of or supplement to the Registration Statement or the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order or of any order preventing or suspending the use of the Registration Statement, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus, (v) of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, (vi) of the initiation or threatening of any proceeding or examination for any such purpose or pursuant to Section 8A of the Act, and (vii) of any request by the Commission for the amending or supplementing of the Registration Statement, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or for additional information. During the period for which a prospectus relating to the Shares is required to be delivered under the Act (whether physically or through compliance with Rule 172 under the Act or any similar rule), the Company will not file (i) any amendment to the Registration Statement or supplement to the Prospectus (excluding documents deemed to be incorporated by reference into the Prospectus) unless the Company has furnished to the Underwriters, the Forward Seller and the Forward Purchaser a copy for their review prior to filing and will not file any such proposed amendment or supplement to which the Underwriters, the Forward Seller or the Forward Purchaser reasonably objects or (ii) any document that would be deemed to be incorporated by reference into the Prospectus without delivering to the Underwriter, the Forward Seller and the Forward Purchaser a copy of the document proposed to be so filed, such delivery to be made at least 24 hours prior to such filing, and the Company will consult with the Underwriters, the Forward Seller and the Forward Purchaser as to any comments which the Underwriters, the Forward Seller or the Forward Purchaser make in a timely manner with respect to such document. During the period for which a prospectus relating to the Shares is required to be delivered under the Act (whether physically or through compliance with Rule 172 under the Act or any similar rule), the Company will promptly file 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 so long as the delivery of a prospectus is required in connection with the offering or sale of the Shares. Following the First Closing Date and, for as long as a prospectus relating to the Shares is required to be delivered under the Act, in the event of the issuance of any stop order or of any order preventing or suspending the use of any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus, the Company will promptly use its best efforts to obtain the withdrawal of such order. In the event of the Company’s receipt of a notice objecting to the use of the form of the Registration Statement or any post-effective amendment thereto, the Company will promptly take such steps including, without limitation, amending the Registration Statement or filing a new registration statement, at its own expense, as may be necessary to permit offers and sales of the Shares by the Underwriters (and references herein to the “Registration Statement” shall include any such amendment or new registration statement).

(b)    If, at any time when a prospectus relating to the Shares is required to be delivered under the Act (whether physically or through compliance with Rule 172 under the Act or any similar rule), any event occurs as a result of which the Pricing Disclosure Package or the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary at any time to amend or supplement the Prospectus to comply with the Act or the Exchange Act or the respective rules and regulations of the Commission thereunder, the Company promptly, subject to paragraph (a) of this Section 4, will prepare and file an amendment or supplement to the Prospectus with the Commission and furnish to the Underwriters, the Forward Seller and the Forward Purchaser a reasonable number of copies thereof, or will make a filing with the Commission pursuant to Section 13 or 14 of the Exchange Act, which will correct such statement or omission or will effect such compliance.

(c)    The Company will make generally available to its security holders and to the Underwriters, the Forward Seller and the Forward Purchaser a consolidated earnings statement (which need not be audited) of the Company, for a twelve-month period beginning after the date of the Prospectus filed pursuant to Rule 424(b) under the Act, as soon as is reasonably practicable after the end of such period, but in any event no later than eighteen months after the “effective date of the Registration Statement” (as defined in Rule 158(c) under the Act), which will satisfy the provision of Section 11(a) of the Act and the rules and regulations of the Commission thereunder (including at the option of the Company, Rule 158).

(d)    The Company will deliver to the Underwriters, the Forward Seller and the Forward Purchaser conformed copies of the Registration Statement, the Preliminary Prospectus, the Prospectus and the Issuer Free Writing Prospectus (including all documents incorporated by reference therein) and, so long as delivery of a prospectus by the Underwriters or a dealer may be required by the Act (whether physically or through compliance with Rule 172 under the Act or any similar rule), all amendments of and supplements to such documents, in each case as soon as available and in such quantities

as the Underwriters, the Forward Seller and the Forward Purchaser may reasonably request.

(e)    Without the prior written consent of the Underwriters, the Forward Seller and the Forward Purchaser, the Company has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Act, it being understood and agreed that the Company’s presentation entitled “Sustainable Long-Term Growth, EEI Conference November 2018,” to the EEI Conference in November 2018 shall not constitute a “free writing prospectus.”

(f)    The Company will promptly file all material required to be filed by the Company with the Commission pursuant to Rule 433(d) under the Act and will retain as and to the extent required by Rule 433 under the Act all Issuer Free Writing Prospectuses not required to be filed with the Commission pursuant to the rules and regulations under the Act. If at any time after the date hereof any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the Pricing Disclosure Package or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, the Company will notify the Underwriters, the Forward Seller and the Forward Purchaser and, upon their request, file such document and prepare and furnish without charge to each Underwriter, the Forward Seller and the Forward Purchaser as many copies as the Underwriters, the Forward Seller or the Forward Purchaser may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus that will correct such conflict, statement or omission or effect such compliance.

(g)    The Company will furnish such information, execute such instruments and take such action as may be required to qualify the Shares for sale under the laws of such jurisdictions in the United States as the Underwriters may designate and will maintain such qualifications in effect so long as required for the distribution of the Shares; provided that the Company shall not be required to qualify to do business in any jurisdiction where it is not now so qualified or to take any action which would subject it to general or unlimited service of process in any jurisdiction where it is not now so subject.

(h)    For a period of two years after the First Closing Date, the Company will furnish (or cause to be furnished) to each of the Underwriters, the Forward Seller and the Forward Purchaser upon request, copies of all reports and financial statements filed with the Commission or any national securities exchange.

(i)    During the 60-day period beginning on the date of this Agreement, the Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, any shares of Common Stock or securities convertible into or exchangeable for any shares of Common Stock, or publicly disclose the intention to make any such

offer, sale, pledge, disposition or filing, without the prior written consent of the Underwriters, the Forward Seller and the Forward Purchaser, except for issuances pursuant to the exercise or conversion of stock options, restricted stock or restricted stock units, or performance shares or performance units or convertible notes outstanding on the date of this Agreement, grants of employee stock options, restricted stock or restricted stock units, or performance shares or performance units pursuant to the terms of a plan in effect on the date of this Agreement, issuances pursuant to the exercise or conversion of such stock options, restricted stock or restricted stock units, or performance shares or performance units, the filing of registration statements on Form S-8 and amendments thereto in connection with such stock options, restricted stock or restricted stock units, or performance shares or performance units or the Company’s employee stock purchase or other employee benefit plans (including the 401(k) plans) in existence on the date of this Agreement, issuances pursuant to the dividend reinvestment and stock purchase plan in place on the date of this Agreement, the issuances pursuant to any dividend reinvestment and stock purchase plan that replaces the Company’s current dividend reinvestment and stock purchase plan, the filing of registration statements on Form S-3 and amendments thereto in connection with such dividend reinvestment and stock purchase plans and issuances of any Company Shares in accordance herewith, the sale, delivery or issuance of any Company Shares pursuant to Section 2(a)(iv) or Section 12 hereof or the sale, delivery or issuance of any shares of Common Stock by the Company pursuant to the Forward Sale Agreement or any Additional Forward Sale Agreement.

(j)    The Company will use its best efforts to effect and maintain the listing of the Company Shares and the Issuable Shares on the Nasdaq Stock Market LLC (“Nasdaq”).

(k)    In connection with the offering of the Shares, until the Underwriters shall have notified the Company and the other Underwriters of the completion of the sale of the Shares, the Company will not, and will use its best efforts to cause its controlled affiliates not to, either alone or with one or more other persons (i) bid for or purchase for any account in which it or any such affiliate has a beneficial interest in any Shares or attempt to induce any person to purchase any Shares or (ii) make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of raising the price of, the Shares.

(l)    The Company will not take, directly or indirectly, any action which is designed to stabilize or manipulate, or which constitutes or which might reasonably be expected to cause or result in stabilization or manipulation, of the price of any security of the Company in connection with the offering of the Shares.

5.    Agreements of the Underwriters. Each Underwriter hereby represents and agrees that:

(a)    It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any Issuer Free Writing Prospectus or any “free writing prospectus,” as defined in Rule 405 under the Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the

Registration Statement and any press release issued by the Company) required to be filed by the Company with the Commission or retained by the Company pursuant to Rule 433 under the Act, other than (i) a free writing prospectus that contains no “issuer information” (as defined in Rule 433(h)(2) under the Act) that was not included (including through incorporation by reference) in the Preliminary Prospectus or a previously filed Issuer Free Writing Prospectus or (ii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in writing.

(b)    It will, pursuant to reasonable procedures developed in good faith, retain, as and to the extent required under Rule 433 under the Act, copies of each free writing prospectus used or referred to by it, in accordance with Rule 433.

(c)    It will notify the Company, the Forward Seller and the Forward Purchaser when the sale of the Shares has been completed.

Whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, the Company will pay all costs and expenses incident to the performance of the obligations of the Company hereunder, including, without limiting the generality of the foregoing, all costs, taxes and expenses incident to the issue (in the case of any Company Shares) and delivery of any Shares to the Underwriters, all fees and expenses of the Company’s counsel and accountants, all costs and expenses incident to the preparation, printing, filing and distribution of the Registration Statement (including all exhibits thereto), any Preliminary Prospectus, the Prospectus (including all documents incorporated by reference therein), any Issuer Free Writing Prospectus and any amendments thereof or supplements thereto, all costs and expenses incurred in connection with “blue sky” qualifications (including all fees and expenses of Counsel for the Underwriters (as defined herein) not to exceed $5,000), all costs and expenses of the printing and distribution of all documents in connection with the offering, the cost of listing any Company Shares and the Issuable Shares on Nasdaq, the fees and expenses of the transfer agent (including related fees and expenses of any counsel to such parties), all expenses and application fees incurred in connection with any filing with, and clearance of any offering by FINRA, and all fees and expenses incident to the transactions contemplated by the Forward Sale Agreement and any Additional Forward Sale Agreement. Except as provided in this Section 6 and Sections 9 and 10 hereof, the Underwriters will pay all their own costs and expenses, including the fees of their counsel, transfer fees on resale of the Shares by them and any advertising expenses in connection with any offer they may make.

7.    Conditions to the Obligations of the Underwriters and the Forward Seller. The several obligation of the Underwriters to purchase the Shares at each Closing Date, and the obligation of the Forward Seller to deliver and sell the Borrowed Firm Shares on the First Closing Date or the Borrowed Option Shares on an Option Closing Date, as the case may be, to the Underwriters, as provided herein, shall be subject, in the discretion of the Underwriters or the Forward Seller, as the case may be, to the accuracy of the representations and warranties on the part of the Company contained herein as of the date hereof and as of such Closing Date, to the accuracy of the statements of the Company’s officers on and as of such Closing Date made in any certificates given pursuant to the

provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

(a)    The Prospectus shall have been filed with the Commission pursuant to Rule 424(b) under the Act within the applicable time period prescribed for such filing by the rules and regulations under the Act and in accordance with Section 4(a) hereof; all filings required by Rule 433 under the Act shall have been made, and no such filings shall have been made without the consent of the Underwriters and the Forward Seller; no stop order suspending the effectiveness of the Registration Statement or any part thereof or preventing or suspending the use of the Prospectus or any Issuer Free Writing Prospectus shall have been issued and no proceeding for that purpose or pursuant to Section 8A of the Act shall have been initiated or threatened by the Commission; no notice of objection of the Commission to the use of the Registration Statement pursuant to Rule 401(g)(2) under the Act has been received by the Company; and all requests for additional information on the part of the Commission shall have been complied with to the Underwriters’, the Forward Seller’s and the Forward Purchaser’s reasonable satisfaction.

(c)    The Underwriters, the Forward Seller and the Forward Purchaser shall have received from Hunton Andrews Kurth LLP, New York, New York, counsel for the Underwriters (“Counsel for the Underwriters”), such opinion or opinions and negative assurance letter dated such Closing Date with respect to such matters as the Underwriters, the Forward Seller and the Forward Purchaser may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(d)    The Company shall have furnished to the Underwriters, the Forward Seller and the Forward Purchaser a certificate of the President, Executive Vice President, Senior Vice President or any Vice President of the Company, dated such Closing Date, as to the matters set forth in paragraphs (a) and (h) of this Section 7 and to the further effect that the signers of such certificate have examined the Registration Statement, the Prospectus and this Agreement and that, to the best of his or her knowledge:

(i)    the representations and warranties of the Company in this Agreement are true and correct on and as of such Closing Date with the same effect as if made on such Closing Date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to such Closing Date; and

(ii)    there has been no material adverse change in the condition of the Company and its subsidiaries taken as a whole, financial or otherwise, whether or not arising in the ordinary course of business, from that set forth in or contemplated by the Registration Statement, the most recent Preliminary Prospectus, or the Prospectus.

(e)    The Underwriters, the Forward Seller and the Forward Purchaser shall have received letters from Deloitte & Touche LLP, independent public accountants for the Company (dated the date of this Agreement and each Closing Date, respectively, and in form and substance satisfactory to the Underwriters, the Forward Seller and the Forward Purchaser) advising that (i) they are an independent registered public accounting firm with respect to the Company as required by the Act and published rules and regulations of the Commission thereunder, (ii) in their opinion, the consolidated financial statements and supplemental schedules included or incorporated by reference in the Registration Statement, the Pricing Disclosure Package or the Prospectus and covered by their opinion filed with the Commission under Section 13 of the Exchange Act comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the published rules and regulations of the Commission thereunder, (iii) that they have performed limited procedures, not constituting an audit, including a reading of the latest available interim financial statements of the Company, a reading of the minutes of meetings of the Board of Directors, committees thereof, and of the shareholders of the Company since the date of the most recent audited financial statements included or incorporated by reference in the Pricing Disclosure Package or the Prospectus, inquiries of officials of the Company responsible for financial accounting matters and such other inquiries and procedures as may be specified in such letter, and on the basis of such limited review and procedures nothing came to their attention that caused them to believe that: (A) (1) any material modifications should be made to any unaudited consolidated financial statements of the Company included or incorporated by reference in the Registration Statement, the Pricing Disclosure Package or the Prospectus for them to be in conformity with generally accepted accounting principles or (2) any unaudited consolidated financial statements of the Company included or incorporated by reference in the Registration Statement, the Pricing Disclosure Package or the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the rules and regulations of the Commission applicable to Form 10-Q; and (B) with respect to the period subsequent to the date of the most recent financial statements included or incorporated by reference in the Pricing Disclosure Package or the Prospectus and except as set forth in or contemplated by the Registration Statement, the Pricing Disclosure Package or the Prospectus, there were any adverse changes, at a specified date not more than three business days prior to the date of the letter, in the capital stock of the Company, incurrences of long-term debt of the Company on a consolidated basis as compared to the amounts shown on the most recent consolidated balance sheet included or incorporated by reference in the Pricing Disclosure Package or the Prospectus or, as of a specified date, there were any decreases in stockholders’ equity or net current assets of the Company on a consolidated basis as compared with the amounts shown on the most recent consolidated balance sheet included or incorporated by reference in the Pricing Disclosure Package or the Prospectus, or for the period from the date of the most recent financial statements

included or incorporated by reference in the Pricing Disclosure Package or the Prospectus to such specified date there were any decreases, as compared with the corresponding period in the preceding year, in operating revenues, operating income or net income of the Company and its subsidiaries, except in all instances for changes or decreases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is not deemed necessary by the Underwriters; and (iv) they have carried out specified procedures performed for the purpose of comparing certain specified financial information and percentages (which is limited to financial information derived from general accounting records of the Company or, to the extent not so derived, from schedules prepared by Company officers responsible for such accounting records) included or incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus with indicated amounts in the financial statements or accounting records of the Company and (excluding any questions of legal interpretation) have found such information and percentages to be in agreement with the relevant accounting and financial information of the Company referred to in such letter in the description of the procedures performed by them.

(f)    Subsequent to the respective dates as of which information is given in the Registration Statement and the Pricing Disclosure Package, there shall not have been any change or decrease specified in the letter or letters referred to in paragraph (e) of this Section 7 which makes it impractical or inadvisable in the judgment of the Underwriters, the Forward Seller or the Forward Purchaser to proceed with the public offering or the delivery of the Shares on the terms and in the manner contemplated by the Pricing Disclosure Package.

(g)    Subsequent to the execution and delivery of this Agreement, (i) no downgrading shall have occurred in the rating accorded any debt securities or preferred stock of or guaranteed by the Company by any “nationally recognized statistical rating organization,” as such term is defined by the Commission for purposes of the Exchange Act (other than downgrades of debt securities issued by or on behalf of governmental entities for the benefit of the Company solely as a result of downgrades of ratings of any third parties insuring such debt securities) and (ii) no such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its rating of the debt securities or preferred stock of or guaranteed by the Company (other than an announcement with positive implications of a possible upgrading and other than with respect to debt securities issued by or on behalf of governmental entities for the benefit of the Company solely as a result of any such announcement with respect to any third parties insuring such debt securities).

(h)    Since the most recent dates as of which information is given in the Pricing Disclosure Package and the Prospectus there has been no material adverse change in the condition of the Company and its subsidiaries taken as a whole, financial or otherwise, whether or not arising in the ordinary course of business, otherwise than as set forth or contemplated in the Pricing Disclosure Package and the Prospectus, the effect of which is in the judgment of the Underwriters, the Forward Seller or the Forward Purchaser so material and adverse as to make it impracticable or inadvisable to proceed with the

offering, sale or the delivery of the Shares on the terms and in the manner contemplated by this Agreement and the Prospectus.

(i)    The Underwriters shall not have advised the Company that the Registration Statement, Pricing Disclosure Package or Prospectus, or any amendment or supplement thereto, contains an untrue statement of fact which in the opinion of Counsel for the Underwriters is material or omits to state a fact which in the opinion of Counsel for the Underwriters is material and is required to be stated therein or is necessary to make the statements therein not misleading.

(j)    No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or regulatory authority that would, as of such Closing Date, prevent the issuance or sale of the Shares; and no injunction or order of any federal, state or foreign court shall have been issued that would, as of such Closing Date, prevent the issuance or sale of the Shares.

(k)    All corporate proceedings and other legal matters incident to the authorization, form and validity of this Agreement and the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable, and the transactions contemplated hereby and thereby shall be reasonably satisfactory to Counsel for the Underwriters, the Forward Seller and the Forward Purchaser and prior to such Closing Date, the Company shall have furnished to the Underwriters, the Forward Seller and the Forward Purchaser such other customary information, certificates and documents as they may reasonably request.

(l)    Any Company Shares to be delivered at such Closing Date and the Issuable Shares shall have been approved for listing on Nasdaq.

(m)     “Lock-up agreements” substantially in the form of Exhibit C hereto shall be executed by the officers of the Company listed on Schedule IV hereto and shall be delivered to the Underwriters on or before the date hereof, shall be in full force and effect at each Closing Date.

(n)    The Forward Sale Agreement shall be in full force and effect at the First Closing Date and any Additional Forward Sale Agreement shall be in full force and effect at the related Option Closing Date.

If any of the conditions specified in this Section 7 shall not have been fulfilled when and as required by this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be satisfactory in form and substance to the Underwriters, the Forward Seller, the Forward Purchaser or their respective counsel, this Agreement and all obligations of the Underwriters, the Forward Seller and the Forward Purchaser hereunder may be cancelled at, or at any time prior to, the First Closing Date, or with respect to any Option Shares the related Option Closing Date, by the Underwriters, the Forward Seller or the Forward Purchaser. Notice of such

cancellation shall be given to the Company in writing, or by telephone, or facsimile transmission confirmed in writing.

8.    Conditions of Company’s and the Forward Seller’s Obligations. The obligations of the Company or the Forward Seller, as applicable, to sell and deliver the Shares at each Closing Date are subject to the condition that prior to each such Closing Date, no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Company, the Underwriters, the Forward Seller or the Forward Purchaser threatened and no notice of objection of the Commission to the use of the Registration Statement pursuant to Rule 401(g)(2) under the Act has been received by the Company.

If this condition shall not have been fulfilled, this Agreement and all obligations of the Company or the Forward Seller, as applicable, hereunder may be cancelled on or at any time prior to, with respect to the Firm Shares, the First Closing Date or, with respect to any Option Shares, the related Option Closing Date by the Company or the Forward Seller, as applicable. Notice of such cancellation shall be given to the Underwriters, the Forward Seller and the Forward Purchaser in writing or by telephone, or facsimile transmission confirmed in writing.

9.    Reimbursement of Underwriters’, the Forward Seller’s and the Forward Purchaser’s Expenses. If the sale of the Shares provided for herein is not consummated because (i) this Agreement is terminated pursuant to Section 13 hereof, (ii) any condition to the obligations of the Underwriters or the Forward Seller set forth in Section 7 hereof is not satisfied or (iii) of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters, the Forward Seller and the Forward Purchaser severally upon demand for all out-of-pocket expenses that shall have been reasonably incurred by them in connection with the proposed purchase and sale of the Shares, including the reasonable fees and disbursements of Counsel for the Underwriters and Davis Polk & Wardwell LLP, as counsel for the Forward Seller and the Forward Purchaser.

10.    Indemnification.

(a)    The Company agrees to indemnify and hold harmless the Underwriters, the Forward Seller and the Forward Purchaser, their respective affiliates, directors and officers and each person, if any, who controls such Underwriter, the Forward Seller or the Forward Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus (or any amendment or supplement thereto), or any Issuer Free Writing Prospectus (or any amendment or supplement

thereto) or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter expressly for use therein.

(b)    The Underwriters agree, severally and not jointly, to indemnify and hold harmless the Company, the Forward Seller, the Forward Purchaser, their respective directors and officers, the Company’s officers who signed the Registration Statement and each person, if any, who controls the foregoing within the meaning of Section 15 of the Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted as such fees and expenses are incurred) that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus or any Issuer Free Writing Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information so furnished consists of the information identified in Section 10(g) hereof as being provided by the Underwriters.

(c)    If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 10 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 10. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person, which may be counsel to the Indemnifying Person, to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 10 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the named parties in any

such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, the Forward Seller, the Forward Purchaser, their affiliates, directors and officers and any control persons of such Underwriter, the Forward Seller or the Forward Purchaser, as the case may be, shall be designated in writing by the Underwriters and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)    If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person on the one hand and the Indemnified Person on the other from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Indemnifying Person on the one hand and the Indemnified Person on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Underwriters, the Forward Seller and the Forward Purchaser shall be deemed to be in the same proportion as (A) in the case of the Company, the net proceeds from the offering of the Shares (before deducting expenses) received by the Company (which proceeds shall include the proceeds to be received by

the Company pursuant to the Forward Sale Agreement and any Additional Forward Sale Agreement, assuming, in each case, Physical Settlement (as defined therein) on the Effective Date (as defined therein)), (B) in the case of the Underwriters, the underwriting discounts and commissions received by the Underwriters from the offering of the Shares as set forth on the cover of the Prospectus, and (C) in the case of the Forward Seller and the Forward Purchaser, the aggregate Spread (as defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable) received by the Forward Purchaser under the Forward Sale Agreement and any Additional Forward Sale Agreement, net of any costs associated therewith, as reasonably determined by the Forward Seller, bear to the aggregate offering price of the Shares as set forth in the Prospectus, plus such Spread (net of such costs). The relative fault of the Indemnified Person on the one hand and the Indemnifying Person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Indemnified Person or by the Indemnifying Person and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e)    The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 10, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and in no event shall the Forward Seller and/or the Forward Purchaser be required to contribute any amount in excess of the aggregate Spread under the Forward Sale Agreement or any Additional Forward Sale Agreement, as the case may be, net of any costs associated therewith, as reasonably determined by the Forward Seller or Forward Purchaser, as the case may be. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 10 are several in proportion to their respective purchase obligations hereunder and not joint.

(f)    The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

(g)    The Underwriters severally confirm and the Company acknowledges that the statements with respect to the offering of the Shares by the Underwriters set forth in

the third, twenty-fourth, twenty-fifth (only as to themselves in the second and third sentences thereof and the fourth sentence thereof), twenty-sixth (only the first sentence thereof) and twenty-seventh paragraphs in the section entitled “Underwriting(Conflicts of Interest)” in the prospectus supplement that is a part of the Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement, the Pricing Disclosure Package or the Prospectus.

11.    Default by an Underwriter.

(a)    If, on any Closing Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Shares that the defaulting Underwriter agreed but failed to purchase on such Closing Date in the respective proportions that the number of shares of the Firm Shares set forth opposite the name of each remaining non-defaulting Underwriter in Schedule I bears to the total number of shares of the Firm Shares set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule I; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Shares on such Closing Date if the total number of the Shares that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the total number of the Shares to be purchased on such Closing Date. If the foregoing maximum is exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to such remaining non-defaulting Underwriter and the Forward Sellers who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Shares to be purchased on such Closing Date. If the remaining Underwriters or other Underwriters satisfactory to such remaining Underwriter and the Forward Seller do not elect to purchase the shares that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Closing Date, this Agreement (or, with respect to an Option Closing Date, the obligation of the Underwriters to purchase, and the Forward Seller or the Company, as applicable, to sell, the relevant Option Shares) shall terminate without liability on the part of any non-defaulting Underwriter, the Forward Seller or the Company, except that the Company will continue to be liable for its obligations set forth in Sections 6, 9 and 10 hereof. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I who, pursuant to this Section 11, purchases Firm Shares which a defaulting Underwriter agreed but failed to purchase.

(b)    Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Forward Purchaser or the Forward Seller for damages caused by its default. If other Underwriters are obligated or agree to purchase the Shares of a defaulting or withdrawing Underwriter, any of the Forward Seller, such non-defaulting Underwriter and the Company may postpone the relevant Closing Date for up to seven full business days in order to effect any changes that in the opinion of Counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

12.    Issuance and Sale by the Company.

(a)    In the event that (i) all the Conditions are not satisfied on or prior to the First Closing Date or, in respect of any Additional Forward Sale Agreement to be entered into pursuant to Section 2(a)(iii) hereof, all the Option Conditions are not satisfied on or prior to the related Option Closing Date, as the case may be, and the Forward Seller elects, pursuant to Section 2(b) or 2(c) hereof, as the case may be, not to deliver and sell to the Underwriters their respective portion of the Borrowed Firm Shares or the Borrowed Option Shares, as applicable, otherwise deliverable by the Forward Seller, (ii) in the Forward Purchaser’s good faith and commercially reasonable judgment the Forward Seller is unable to borrow and deliver for sale under this Agreement the number of shares of Common Stock equal to the number of Borrowed Firm Shares or Borrowed Option Shares, as applicable, deliverable by the Forward Seller hereunder or (iii) in the Forward Purchaser’s good faith and commercially reasonable judgment the Forward Seller would incur a Stock Loan Fee (as defined under the Forward Sale Agreement or relevant Additional Forward Sale Agreement, as applicable) of more than a rate equal to 200 basis points per annum to do so, then, in each case, the Company shall issue and sell to the several Underwriters, pursuant to Section 2(a)(iii) or 2(a)(iv), as the case may be, in whole but not in part, an aggregate number of shares of Common Stock equal to the number of Borrowed Firm Shares or Borrowed Option Shares, as the case may be, that the Forward Seller does not so deliver and sell to the Underwriters. In connection with any such issuance and sale by the Company, the Company or the Underwriters shall have the right to postpone the relevant Closing Date for a period not exceeding two (2) business days in order to effect any required changes in any documents or arrangements. The shares of Common Stock sold by the Company to the Underwriters pursuant to this Section 12(a) in lieu of Borrowed Firm Shares are referred to herein as the “Company Top-Up Firm Shares” and the shares of Common Stock sold by the Company to the Underwriter pursuant to this Section 12(a) in lieu of Borrowed Option Shares are referred to herein as the “Company Top-Up Option Shares.”

(b)    Neither the Forward Seller nor the Forward Purchaser shall have any liability whatsoever for any Borrowed Shares that the Forward Seller does not deliver and sell to the Underwriters or any other party if (i) all of the Conditions are not satisfied on or prior to the First Closing Date, in the case of Borrowed Firm Shares, or all of the Option Conditions are not satisfied on or prior to the relevant Option Closing Date, in the case of Borrowed Option Shares, and the Forward Seller elects, pursuant to Section 2(b) or 2(c) hereof, as the case may be, not to deliver and sell to the Underwriters their respective portion of the Borrowed Firm Shares or the Borrowed Option Shares (or, in the case of the Borrowed Option Shares, a pro rata portion thereof if the Underwriters’ option is not exercised in full), as applicable, otherwise deliverable by the Forward Seller, (ii) in the good faith, commercially reasonable judgment of the Forward Purchaser, the Forward Seller is unable to borrow and deliver for sale under this Agreement the number of shares of Common Stock equal to the number of Borrowed Firm Shares or Borrowed Option Shares, as applicable, deliverable by the Forward Seller hereunder or (iii) in the good faith, commercially reasonable judgment of the Forward Purchaser, the Forward Seller would incur a Stock Loan Fee (as defined under the Forward Sale Agreement or

relevant Additional Forward Sale Agreement, as applicable) of more than a rate equal to 200 basis points per annum to do so.

13.    Termination. This Agreement (or, with respect to an Option Closing Date, the obligation of the Underwriters to purchase, and the Forward Seller or Company, as applicable, to sell, the related Option Shares) shall be subject to termination in the absolute discretion of the Underwriters, by notice given to the Company, the Forward Seller and the Forward Purchaser prior to delivery of and payment for the relevant Shares on the relevant Closing Date, if prior to such time (i) trading shall have been suspended or materially limited on the New York Stock Exchange, Nasdaq or the over-the-counter market, (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities or a material disruption in commercial banking or securities clearance or settlement services shall have occurred or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Underwriters, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the terms and in the manner contemplated by this Agreement and the Prospectus.

14.    Representations and Indemnities to Survive Delivery. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers, of the Underwriters and of the Forward Seller set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Company, the Forward Seller or any of their respective officers, directors or controlling persons within the meaning of the Act, and will survive delivery of and payment for the Shares. The provisions of Sections 6, 9 and 10 hereof shall survive the termination or cancellation of this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement.
