The Company proposes to issue and sell through or to the Managers, as sales agents and/or principals, shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), having an aggregate gross sales price of up to $100,000,000 (the “Shares”) on the terms set forth in Section 3 of this Agreement. The Company agrees that whenever it determines to sell the Shares directly to any Manager as principal, it will enter into a separate agreement (each, a “Terms Agreement”), in form and substance satisfactory to such Manager, relating to such sale in accordance with Section 3 of this Agreement. The Company and the Managers understand that the aggregate gross sales price of Shares to be sold pursuant to this Agreement shall not exceed $100,000,000 in the aggregate (the “Maximum Program Amount”).

SECTION 2. Representations and Warranties of the Company. The Company represents and warrants to and agrees with the Managers that:

(a) An “automatic shelf registration statement” (the “registration statement”) as defined in Rule 405 under the Securities Act of 1933, as amended, and the rules and regulations of the Securities and Exchange Commission (the “Commission”) thereunder (collectively, the “Act”), on Form S-3 (File No. 333-202126) in respect of the Shares, including a form of prospectus, has been prepared and filed by the Company not earlier than three years prior to the date hereof, in conformity with the requirements of the Act.

The registration statement contains certain information concerning the offering and sale of the Shares, and contains additional information concerning the Company, its business and the Common Stock; the Commission has not issued an order preventing or suspending the use of the Basic Prospectus (as defined below), the Prospectus Supplement (as defined below), the Prospectus (as defined below) or any Permitted Free Writing Prospectus (as defined below), or the effectiveness of the Registration Statement (as defined below), and no proceeding for that purpose or pursuant to Section 8A of the Act has been instituted or, to the Company’s knowledge, threatened by the Commission. Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the Managers, as well as any new registration statement, post-effective amendment or new automatic shelf registration statement as may have been filed pursuant to Section 4(f) or (g) of this Agreement, including (1) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein, (2) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act, to the extent such information is deemed, pursuant to Rule 430B or Rule 430C under the Act, to be part of the registration statement at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the Managers, and (3) any registration statement filed to register the offer and sale of Shares pursuant to Rule 462(b) under the Act.

Except where the context otherwise requires, “Prospectus,” as used herein, means the Prospectus Supplement together with the Basic Prospectus attached to or used with the Prospectus Supplement. Notwithstanding the foregoing, if any revised basic prospectus, prospectus supplement or prospectus shall be provided to the Managers by the Company for use in connection with the offering and sale of the Shares which differs from the Basic Prospectus, Prospectus Supplement or Prospectus, as the case may be (whether or not such revised basic prospectus, prospectus supplement or prospectus is required to be filed by the Company pursuant to Rule 424(b) under the Act), the terms “Basic Prospectus,” “Prospectus Supplement” and “Prospectus” shall refer to such revised basic prospectus, prospectus supplement or prospectus, as the case may be, from and after the time it is first provided to the Managers for such use. “Permitted Free Writing Prospectuses,” as used herein, means the documents listed on Schedule A attached hereto and any other “issuer free writing prospectus” (as defined in Rule 433 under the Act) that the Company and the Managers shall agree from time to time is a Permitted Free Writing Prospectus.

reference, or deemed to be incorporated by reference, therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents.

(ii) None of the Company, any of its Subsidiaries or, 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 would result in a violation by such persons 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 or any other applicable anti-bribery laws, and the Company, its Subsidiaries and, to the knowledge of the Company, its other affiliates have conducted their businesses in compliance with the FCPA and any other applicable anti-bribery laws. The Company has instituted and maintains policies and procedures designed, in its reasonable judgment, to ensure, and which are reasonably expected to ensure, continued compliance therewith.

(jj) 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 rules, regulations or guidelines, issued, administered or enforced by any arbitrator, court, governmental body, regulatory body, administrative agency or other authority, body or agency having jurisdiction over the Company or any of its Subsidiaries or any of their respective properties, assets or operations (each, a “Governmental Entity”) (collectively, the “Money Laundering Laws”).

(kk) None of the Company, any of its Subsidiaries or, 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 an individual or entity (“Person”) currently the subject or target of any sanctions administered or enforced by the United States Government, including, without limitation, the U.S. Department of the Treasury’s Office of Foreign Assets Control or other relevant sanctions authority (collectively, “Sanctions”). None of the Company or any of its subsidiaries is located, organized or resident in a country or territory that is the subject of Sanctions. The Company will not, directly or indirectly, use the proceeds of the sale of the Shares, or lend, contribute or otherwise make available such proceeds to any of its subsidiaries, joint venture partners or other Persons, to fund any activities of or business with any Person, or in any country or territory, that, at the time of such funding, is the subject of Sanctions or in any other manner that will result in a violation by any Person (including any Person participating in the transaction, whether as agent, underwriter, advisor, investor or otherwise) of Sanctions.

In addition, any certificate signed by any officer of the Company or any of the Subsidiaries and delivered to the Managers or counsel for the Managers in connection with the offering of the Shares shall be deemed to be a representation and warranty by the Company, as to matters covered thereby, to the Managers.

(a) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell through a Manager, as sales agent, and such Manager agrees to use its commercially reasonable efforts to sell, as sales agent for the Company, the Shares on the following terms.

(i) The Shares are to be sold on a daily basis or otherwise as shall be agreed to by the Company and the applicable Manager on any day that (A) is a trading day for the NYSE (a “Trading Day”) (other than a Trading Day on which the NYSE is scheduled to close prior to its regular weekday closing time), (B) the Company has submitted to such Manager its order (including any price, time or size limits or other customary parameters or conditions) from any of the individuals listed as authorized representatives of the Company on Schedule C hereto (the “Authorized Company Representatives”) to make such sales, in a form and manner as mutually agreed to by the Company and such Manager, and (C) the Company has satisfied its obligations under Section 6 of this Agreement. The Company may sell Shares on any Trading Day through only one of the Managers, but not both. The maximum number of Shares to be sold by any Manager daily shall not in any event exceed (i) the Maximum Program Amount, as reduced by prior sales of Shares under this Agreement by either Manager, (ii) the amount of Shares available for issuance under the currently effective Registration Statement or (iii) the amount of Shares authorized from time to time to be issued and sold under this Agreement by the Company’s board of directors, or a duly authorized committee thereof, or (iv) the amount of Shares approved for listing on the NYSE and, in each case, disclosed to such Manager in writing. Subject to the terms and conditions hereof, each

Manager shall use its commercially reasonable efforts to offer and sell all of the Shares designated to be sold by it on any day; provided, however, that the Managers shall have no obligation to offer or sell any Shares, and the Company acknowledges and agrees that the Managers shall have no such obligation, in the event that an offer or sale of the Shares on behalf of the Company may in the judgment of a Manager constitute the sale of a “block” under Rule 10b-18(a)(5) under the Exchange Act or a “distribution” within the meaning of Rule 100 of Regulation M under the Exchange Act or such Manager reasonably believes it may be deemed to be an “underwriter” under the Act in a transaction that is other than by means of ordinary brokers’ transactions between members of the NYSE that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 under the Act (such ordinary brokers’ transactions are hereinafter referred to as “At the Market Offerings”). On any Trading Day, the Company shall give at least one business day’s prior written notice by telecopy or email to the applicable Manager as to any change of such Manager through which sales of Shares as sales agent will be made. For avoidance of doubt, this Section 3(a)(i) shall not apply to sales solely to employees or security holders of the Company or its Subsidiaries or to a trustee or other person acquiring the Shares for the accounts of such persons in which Merrill Lynch or J.P. Morgan is acting for the Company in a capacity as other than as a Manager under this Agreement.

(ii) Notwithstanding the foregoing, the Company, through any of the Authorized Company Representatives, may instruct any Manager (confirmed promptly by electronic mail) not to sell the Shares if such sales cannot be effected at or above the price designated by the Company in any such instruction. In addition, the Company or any Manager may, upon notice to the other party hereto (confirmed promptly by electronic mail), suspend the offering of the Shares; provided, however, that such suspension shall not affect or impair the parties’ respective obligations with respect to the Shares sold hereunder prior to the giving of such notice.

(iii) Each of the Managers hereby covenants and agrees not to make any sales of the Shares on behalf of the Company, pursuant to this Section 3(a), other than (A) by means of At the Market Offerings and (B) such other sales of the Shares on behalf of the Company in its capacity as agent of the Company as shall be agreed by the Company and such Manager.

(iv) The compensation to each Manager, as an agent of the Company, for sales of the Shares shall be at a mutually agreed rate, not to exceed 2.0% of the gross sales price of the Shares sold by it pursuant to this Section 3(a). The remaining proceeds, after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in connection with such sales, shall constitute the net proceeds to the Company for such Shares (the “Net Proceeds”).

(v) Each Manager shall provide written confirmation to the Company following the close of trading on the NYSE each day in which the Shares are sold under this Section 3(a) setting forth the aggregate amount of the Shares sold on such day, the aggregate Net Proceeds to the Company, and the aggregate compensation payable by the Company to such Manager with respect to such sales.

(vi) Settlement for sales of the Shares pursuant to this Section 3(a) will occur on the second (2^nd) business day that is also a Trading Day following the date on which such sales are made, in either case unless another date shall be agreed to in writing by the Company and the Managers (each such date, a “Settlement Date”). As used in the preceding sentence and in Section 7 below, the term “business day” means any day other than a Saturday, Sunday or other day on which commercial banks in The City of New York are authorized or required by law, regulation or executive order to close. On each Settlement Date, the Shares sold through a Manager for settlement on such date shall be issued and delivered by the Company to such Manager against payment of the Net Proceeds for the sale of such Shares. Settlement for all such Shares shall be effected by free delivery of the Shares by the Company or its transfer agent to such Manager’s account, or to the account of such Manager’s designee, at The Depository Trust Company (“DTC”) through its Deposit and Withdrawal at Custodian System (“DWAC”) 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 eligible for delivery through DTC, in return for payments 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 (A) indemnify and hold such Manager harmless against any loss, claim or damage arising from or as a result of such default by the Company and (B) pay such Manager any commission to which it would otherwise be entitled absent such default. The Authorized Company Representatives shall be the contact persons for the Company for all matters related to the settlement of the transfer of the Shares through DWAC for purposes of this Section 3(a)(vi).

(vii) At each time of an order submitted by the Company pursuant to Section 3(a)(i) hereof, Time of Sale, Settlement Date and Representation Date (as defined in Section 4(q)), the Company shall be deemed to have affirmed each representation and warranty contained in this Agreement, except such representations and warranties that speak as of a specific date, as set forth in Sections 2(d), 2(e) and 2(h)(i). Any obligation of any Manager to use its commercially reasonable efforts to sell the Shares on behalf of the Company shall be subject to the continuing accuracy of the representations and warranties of the Company herein, except such representations and warranties that speak as of a specific date, as set forth in Sections 2(d), 2(e) and 2(h)(i), to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

(b) If the Company wishes to issue and sell the Shares other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify a Manager of the proposed terms of such Placement. If such Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Company, wishes to accept amended terms, such Manager and the Company will enter into a Terms Agreement setting forth the terms of such Placement. In the event of a conflict between the terms of this Agreement and the terms of any Terms Agreement, the terms of such Terms Agreement will control.

(c)(i) Under no circumstances shall the Company cause or request the offer or sale of any Shares if, after giving effect to the sale of such Shares, the aggregate gross sales proceeds or the aggregate number of the Shares sold pursuant to this Agreement would exceed the lesser of (A) the Maximum Program Amount, (B) the amount available for offer and sale under the currently effective Registration Statement, (C) the amount authorized from time to time to be issued and sold under this Agreement by the Company’s board of directors, or a duly authorized committee thereof, or (D) the amount approved for listing on the NYSE and, in each case, disclosed to the Managers in writing. Under no circumstances shall the Company cause or request the offer or sale of any Shares at a price lower than the minimum price authorized from time to time by the Company’s board of directors or a duly authorized committee thereof, and notified to the Managers in writing. The Managers shall have no responsibility for maintaining records with respect to the Shares available for sale under the Registration Statement or for determining the aggregate gross sales price, number or minimum price of Shares duly authorized by the Company.

(ii) If either party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Shares, it shall promptly notify the other party and sales of the Shares under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(d) Each sale of the Shares to or through any Manager shall be made in accordance with the terms of this Agreement or, if applicable, a Terms Agreement.

(e) Subject to such further limitations on offers and sales of Shares or delivery of instructions to offer and sell Shares as are set forth herein and as may be mutually agreed upon by the Company and the Managers, offers and sales of Shares pursuant to this Agreement shall not be requested by the Company and need not be made by any Manager at any time when or during any period in which the Company is or could be deemed to be in possession of material non-public information.

(f) The Company acknowledges and agrees that (A) there can be no assurance that any Manager will be successful in selling the Shares, (B) no Manager will incur liability or obligation to the Company or any other person or entity if it does not sell Shares for any reason other than a failure by such Manager to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Shares in accordance with the terms of this Agreement, and (C) no Manager shall be under any obligation to purchase Shares on a principal basis pursuant to this Agreement, except as otherwise specifically agreed in writing by such Manager and the Company pursuant to a Terms Agreement.

(a) To notify the Managers promptly of the time on or after the date of this Agreement when the Registration Statement or any amendment to the Registration Statement has been filed or become effective or when the Basic Prospectus, the

Prospectus or any Permitted Free Writing Prospectus or any supplement to any of the foregoing has been filed; to prepare and file with the Commission, promptly upon the Managers’ request, any amendments or supplements to the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus that, in the Managers’ reasonable opinion, may be necessary or advisable in connection with the offering of the Shares by the Managers; and to cause the Basic Prospectus, the Prospectus Supplement and the Prospectus and each amendment or supplement to the Basic Prospectus, the Basic Prospectus or the Prospectus to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424(b) under the Act (without reliance on Rule 424(b)(8)) or, in the case of any Incorporated Document, to be filed with the Commission as required pursuant to the Exchange Act, within the time period prescribed; to cause each Permitted Free Writing Prospectus to be filed with the Commission as required by Rule 433 under the Act (to the extent such filing is required by such rule) and to retain copies of each Permitted Free Writing Prospectus that is not required to be filed with the Commission in accordance with Rule 433 under the Act.

(c) To make available to the Managers, as soon as practicable after this Agreement becomes effective, and thereafter from time to time to furnish to the Managers, as many copies of the Prospectus and each Permitted Free Writing Prospectus (or of the Prospectus or any Permitted Free Writing Prospectus as amended or supplemented if the Company shall have made any amendments or supplements thereto after the effective date of the Registration Statement) as the Managers may request for the purposes contemplated by the Act; in case the Managers are required to deliver (whether physically, deemed to be delivered pursuant to Rule 153 or through compliance with Rule 172 under the Act or any similar rule), in connection with the sale of the Shares, a prospectus after the nine-month period referred to in Section 10(a)(3) of the 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 Act, the Company will prepare, at its expense, such amendment or amendments to the Registration Statement and the Prospectus as may be necessary to permit compliance with the requirements of Section 10(a)(3) of the Act or Item 512(a) of Regulation S-K under the Act, as the case may be.

(including the reasonable cost of investigation), as incurred, which, jointly or severally, the Managers or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post effective amendment thereof by the Company) or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning any Manager furnished in writing by or on behalf of such Manager to the Company expressly for use in, the Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (the term Prospectus for the purpose of this Section 7 being deemed to include any Basic Prospectus, any Prospectus Supplement, any Prospectus and any amendments or supplements to the foregoing), in any Permitted Free Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Company or in any Prospectus together with any combination of one or more of the Permitted Free Writing Prospectuses, if any, or arises out of or is based upon any omission or alleged omission 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, except, with respect to such Prospectus or Permitted Free Writing Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning any Manager furnished in writing by or on behalf of such Manager to the Company expressly for use in, such Prospectus or Permitted Free Writing Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(b) Each Manager, severally and not jointly, agrees to indemnify, defend and hold harmless the Company, its directors and officers, and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Company or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning any Manager furnished in writing by or on behalf of such Manager to the Company expressly for use in, the Registration Statement (or in the Registration Statement as

amended by any post effective amendment thereof by the Company), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Manager furnished in writing by or on behalf of such Manager to the Company expressly for use in, the Prospectus Supplement or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in the Prospectus Supplement or a Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(c) If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Company or any Manager (as applicable, the “indemnifying party”) pursuant to subsection (a) or (b), respectively, of this Section 7, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all reasonable and documented fees and expenses; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party or otherwise, except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure. The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding or the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The indemnifying party shall not be liable for any settlement of any Proceeding effected without its written consent but, if settled with its written consent, such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability, as incurred, by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an

indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this Section 7(c), then 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 90 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(d) If the indemnification provided for in this Section 7 is unavailable to an indemnified party under subsections (a) and (b) of this Section 7 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the applicable Manager, on the other hand, from the offering of the Shares 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 of such Manager, on the other hand, in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the applicable Manager, on the other, shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of discounts and commissions but before deducting expenses) received by the Company, and the total discounts and commissions received by such Manager, bear to the aggregate gross sales price of the Shares. The relative fault of the Company, on the one hand, and of the applicable Manager, on the other, shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by such Manager 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, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding. For the avoidance of doubt, any obligations of the Managers under this Section 7(d) shall be several, and not joint.

(e) The Company and each Manager agrees that it would not be just and equitable if contributions pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (d) above. Notwithstanding the provisions of this Section 7, no Manager shall be required to contribute any amount in excess of commissions received by it under this Agreement. 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.

SECTION 8. Representations and Agreements to Survive Delivery. The indemnity and contribution agreements contained in Section 7 hereof and the covenants, warranties and representations of the Company contained in this Agreement or in certificates delivered pursuant hereto shall remain in full force and effect regardless of any investigation made by or on behalf of any Manager or any of its affiliates or its or their directors, officers, employees or agents or any person (including each director, officer, employee or agent of such person) who controls such Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Company, its directors or officers or any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Shares.

(a) The Company shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Shares in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) if any of the Shares have been sold through any Manager for the Company, then Section 4(x) shall remain in full force and effect, (ii) with respect to any pending sale, through any Manager for the Company, the obligations of the Company, including in respect of compensation of such Manager, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Sections 5, 7, 8, 10, 11, 12, 16, 17, 18, 19 and 20 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) Each Manager, as to itself, shall have the right, by giving written notice as hereinafter specified, to terminate its own obligations under this Agreement relating to the solicitation of offers to purchase the Shares in its sole discretion at any time; provided, however, that this Agreement and the obligations hereunder will remain in full force and effect with respect to the other Manager that has not so terminated its obligations. Any such termination shall be without liability of any party to any other party except that the provisions of Sections 5, 7, 8, 10, 11, 12, 16, 17, 18, 19 and 20 of this Agreement shall remain in full force and effect notwithstanding such termination.

(c) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 9(a) or (b) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that the provisions of Sections 5, 7, 8, 10, 11, 12, 16, 17, 18, 19 and 20 of this Agreement shall remain in full force and effect notwithstanding such termination.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Managers or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of the Shares, such sale shall settle in accordance with the provisions of Section 3(a)(vi) of this Agreement.

SECTION 10. Notices. Except as otherwise herein provided, all statements, requests, notices and agreements under this Agreement shall be in writing and delivered by hand, overnight courier, mail or facsimile and, if to the Managers, shall be sufficient in all respects if delivered or sent to Merrill Lynch, Pierce, Fenner & Smith Incorporated, One Bryant Park, New York, New York 10036, Attention: David Moran, Thomas J.

Very truly yours, NORTHWESTERN CORPORATION

By:		/s/ Brian Bird
		Name: Brian Bird Title: Vice President and Chief Financial Officer

None as of the date of the Equity Distribution Agreement to which this Schedule is attached.

I am the Senior Corporate Counsel and Corporate Secretary of NorthWestern Corporation, a Delaware corporation (the “Company”), and in such capacity I have acted as counsel to the Company in connection with the issuance and sale of shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), having an aggregate gross sales price of up to $100,000,000, through or to Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC (collectively, the “Sales Agents”), in one or more public offerings from time to time, pursuant to the Equity Distribution Agreement, dated as of September 6, 2017 (the “Distribution Agreement”), by and between the Company and the Sales Agents. This letter is furnished to the Sales Agents pursuant to Section 6(c) of the Distribution Agreement. Except as otherwise defined herein, terms used in this letter but not otherwise defined herein are used as defined in the Distribution Agreement.

In connection with the opinions and views expressed herein, I, or attorneys under my supervision, have examined such documents, records and matters of law as we have deemed relevant or necessary for purposes of such opinions and views. Based on the foregoing, and subject to the further limitations, qualifications and assumptions set forth herein, I am of the opinion that:

I, or attorneys under my supervision, have participated in the preparation of the Company’s registration statement on Form S-3 (Registration No. 333-202126) (the “Registration Statement”), the prospectus, dated February 17, 2015 (the “Base Prospectus”), and the prospectus supplement, dated September 6, 2017 (together with the Base Prospectus, the “Prospectus”). In connection therewith, I, or attorneys under my supervision, (a) have made investigations as to the accuracy of certain of the statements of fact contained therein and (b) have discussed other matters with officers and other representatives of the Company, with representatives of Deloitte & Touche LLP, the independent registered public accounting firm who reviewed the financial statements of the Company incorporated by reference in the Registration Statement and the Prospectus, and with representatives of the Sales Agents and their counsel concerning the information contained in or incorporated by reference in the Registration Statement and the Prospectus and the responses to various items of Form S-3. Any reference herein to the Registration Statement or the Prospectus shall be deemed to refer to and include the documents incorporated or deemed to be incorporated by reference (collectively, the “Exchange Act Documents”). Based on the participations, investigations and discussions described above, I am of the view that each of the Exchange Act Documents that was filed with the Commission prior to the date of this letter at the time of filing complied as to form in all material respects with the requirements of the Exchange Act and the rules and regulations thereunder, except that I express no view with respect to (i) the financial statements, financial schedules and other financial data included or incorporated by reference therein or (ii) the information referred to under the caption “Experts” as having been included or incorporated by reference therein on the authority of Deloitte & Touche LLP as experts.

I am not passing upon, and do not assume responsibility for, the accuracy, completeness or fairness of the statements included or incorporated by reference in the Registration Statement or the Prospectus. Based on my participation and discussions, and the participation and discussions of attorneys under my supervision, described above, no facts have come to my attention that cause me to believe that the Registration Statement (including all information deemed to be part of and included therein pursuant to Rule 430B under the Securities Act), as of the date hereof, contained any 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 that the Prospectus, as of the date hereof includes any untrue statement of a material fact or omits 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, except that I express no view with respect to (i) the financial statements, financial schedules and other financial data included or incorporated by reference therein or (ii) the information referred to under the caption “Experts” as having been included or incorporated by reference therein on the authority of Deloitte & Touche LLP as experts.

The opinions and views set forth above are subject to the following limitations, qualifications and assumptions:

As to facts material to the opinions and assumptions expressed herein, I have, with your consent, relied upon oral or written statements and representations of officers and other representatives of the Company and others.

The opinions expressed in paragraphs 1, 2 and 3 above with respect to the existence, good standing and/or foreign qualifications to do business, as the case may be, of the Company and its Subsidiaries referred to therein, are based solely on certificates of public officials as to factual matters or legal conclusions set forth therein.

The opinions and views expressed herein are limited to the federal laws of the United States of America, the laws of the States of South Dakota and Montana and the Delaware General Corporation Law, including applicable provisions of the Delaware Constitution and the reported judicial decisions interpreting such law, in each case as currently in effect, and I express no opinion or view as to the effect of the laws of any other jurisdiction.

The opinions and views expressed herein are limited to the specific issues addressed and to laws existing on the date hereof. By rendering this opinion letter, I do not undertake to advise you with respect to any other matter or of any change in such laws or in the interpretation thereof that may occur after the date hereof. Jones Day, as special counsel to the Company, and Hunton & Williams LLP, as counsel to the Sales Agents, may rely on this opinion letter in connection with the transactions contemplated by the Distribution Agreement.

We have acted as special counsel to NorthWestern Corporation, a Delaware corporation (the “Company”), in connection with the issuance and sale of shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), having an aggregate gross sales price of up to $100,000,000 (the “Authorized Shares”), to be offered by the Company through or to Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC (each a “Manager” and collectively, the “Managers”), in one or more public offerings from time to time, pursuant to the Equity Distribution Agreement, dated as of September 6, 2017 (the “Distribution Agreement”), by and between the Company and the Managers. This letter is furnished to the Managers pursuant to Section 6(d) of the Distribution Agreement. Except as otherwise defined herein, terms used in this letter are used as defined in the Distribution Agreement.

In connection with the opinions and views expressed herein, we have examined such documents, records and matters of law as we have deemed relevant or necessary for purposes of such opinions and views. Based on the foregoing, and subject to the further limitations, qualifications and assumptions set forth herein, we are of the opinion that:

We have participated in the preparation of the Company’s registration statement on Form S-3 (Registration No. 333-202126) (the “Registration Statement”), the prospectus, dated February 17, 2015 (the “Base Prospectus”), and the prospectus supplement, dated September 6, 2017 (together with the Base Prospectus, the “Prospectus”). Each of the Registration Statement and the Prospectus includes the documents incorporated or deemed incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act. From time to time, we have had discussions with certain officers, directors and employees of the Company, with representatives of Deloitte & Touche LLP, the independent registered public accounting firm that examined the financial statements of the Company included or incorporated by reference in the Registration Statement and the Prospectus, with the Managers and with counsel to the Managers concerning the information contained in or incorporated by reference in the Registration Statement and the Prospectus and the proposed responses to various items in Form S-3. Based on our participation and discussions described above, we are of the view that the Registration Statement (including all information deemed to be part of and included therein pursuant to Rule 430B under the Securities Act), as of the date hereof, and the Prospectus, as of the date hereof, complies as to form in all material respects with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission (the “Commission”) thereunder, except that, in each case, we express no view with respect to the financial statements and reports relating thereto, financial schedules and other financial data included or incorporated by reference therein or excluded therefrom.

We have not independently verified and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness (except as and to the extent set forth in paragraph 3 above) of the information contained or incorporated by reference in the Registration Statement and the Prospectus. Based on the participation and discussions set forth above, however, no facts have come to our attention that cause us to believe that the Registration Statement (including all information deemed to be part of and included therein pursuant to Rule 430B under the Securities Act), as of the date hereof, contains any untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Prospectus, as of the date hereof, includes any untrue statement of a material fact or omits 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, except that, in each case, we express no view with respect to the financial statements and reports relating thereto, financial schedules and other financial data included or incorporated by reference therein or excluded therefrom.

Assuming the accuracy of the representations and warranties of the Company set forth in Section 2(c) of the Distribution Agreement, the Registration Statement has become effective under the Securities Act. In addition, based solely upon our review of the website of the Commission, no stop order suspending the effectiveness of Registration Statement has been issued and no proceedings for that purpose are pending or threatened by the Commission.

The opinions and views set forth above are subject to the following limitations, qualifications and assumptions:

We have assumed, for purposes of the opinions and views expressed herein, the legal capacity of all natural persons executing documents, the genuineness of all signatures, the authenticity of original and certified documents and the conformity to original or certified documents of all copies submitted to us as conformed or reproduction copies.

As to facts material to the opinions and assumptions expressed herein, we have, with your consent, relied upon oral or written statements and representations of officers and other representatives of the Company and others, including the representations and warranties of the Company in the Distribution Agreement. We have not independently verified such matters.

With respect to our opinions expressed in paragraph 2 above, we have assumed that (i) the resolutions authorizing the Company to issue and deliver and sell the Authorized Shares pursuant to the Distribution Agreement will be in full force and effect at all times at which the Authorized Shares are issued or delivered or sold by the Company, and the Company will take no action inconsistent with such resolutions, and (ii) the timing of, the terms of and the consideration for each issuance of the Authorized Shares by the Company under the Equity Distribution Agreement will be approved by the Board of Directors of the Company (the “Board of Directors”) or an authorized committee or subcommittee of the Board of Directors.

In connection with the opinions and views expressed herein, we have been advised that the issuance and sale of the Authorized Shares by the Company was authorized and approved pursuant to the FERC Order and by the order of the Montana Public Service Commission on January 28, 2016, and we have assumed that such orders are final and in full force and effect on the date hereof.

The opinions and views expressed herein are limited to the federal securities laws of the United States of America, the laws of the State of New York and the DGCL, each as currently in effect, and we express no opinion or view as to the effect of the laws of any other jurisdiction on the opinions and views expressed herein. Our opinions and views are limited to those expressly set forth herein, and we express no opinion or view by implication.

This letter is furnished by us to you solely for your benefit and solely in your capacity as the Managers under the Distribution Agreement, upon the understanding that we are not hereby assuming any professional responsibility to any other person whatsoever, and that this letter is not to be used, circulated, quoted or otherwise referred to for any other purpose.
