(i) The Offered Shares are to be sold by one of the Managers on a daily basis or otherwise as shall be agreed to by the Company and such Manager on any day that (A) is a trading day for the NYSE (other than a day on which the NYSE is scheduled to close prior to its regular weekday closing time), (B) the Company, through any of the individuals listed as “Authorized Representatives” on Schedule II hereto, has instructed any Manager by telephone (confirmed promptly by electronic mail) to make such sales and (C) the Company has satisfied its obligations under Section 6 of this Agreement; provided , however , that the Company will only submit its orders to one of the Managers on any given single trading day. The Company will designate the maximum amount of the Offered Shares to be sold by any Manager daily as agreed to by such Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per Offered Share at which such Offered Shares may be sold. Subject to the terms and conditions hereof, the applicable Manager shall use its reasonable efforts to sell on a particular day all of the Offered Shares designated for the sale by the Company on such day. The gross sales price of the Offered Shares sold under this Section 3(a) shall be the market price for the Company’s Common Stock sold by the Managers under this Section 3(a) at the time of sale of such Offered Shares.

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

(iii) The Company shall not authorize the issuance and sale of, and each Manager shall not be obligated to use its reasonable efforts to sell, any Offered Shares at a price lower than the minimum price therefor designated from time to time by the board of directors of the Company (the “ Board ”), or a duly authorized committee thereof, and notified to such Manager in writing, or in a number in excess of the number of shares of Common Stock approved for listing on the NYSE. The Company, through any Authorized Representatives, or any Manager may, upon notice to the Company or such Manager, as applicable, by telephone (confirmed promptly by electronic mail), suspend or terminate the offering of the Offered Shares with respect to which such Manager is acting as sales agent for any reason and at any time; provided , however , that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Offered Shares sold hereunder prior to the giving of such notice.

(iv) Each Manager hereby covenants and agrees not to make any sales of the Offered Shares on behalf of the Company pursuant to this Section 3(a), other than (A) (1) by means of ordinary brokers’ transactions between members of the NYSE that qualify for delivery of a Prospectus in accordance with Rule 153 under the Act (such transactions are hereinafter referred to as “ Continuous Offerings ”), (2) to or through a market maker or (3) directly on or through any other national securities exchange or facility thereof, a trading facility of a national securities association, an alternative trading system, an electronic communication network, a “dark pool” or any similar market venue and (B) such other sales of the Offered Shares on behalf of the Company in its capacity as agent of the Company as shall be agreed by the Company and such Manager pursuant to a Terms Agreement.

(v) The compensation to each Manager for sales of the Offered Shares with respect to which such Manager acts as sales agent under this Agreement shall be up to, but not to exceed, 2.0% of the gross sales price of the Offered Shares sold by such Manager pursuant to this Section 3(a) and payable as described in the succeeding subsection (vi) below. The foregoing rate of compensation shall not apply when such Manager acts as principal, in which case the Company may sell Offered Shares to such Manager as principal at a price agreed upon at the relevant Applicable Time pursuant to a Terms Agreement. The remaining proceeds, after deduction of the compensation to such Manager and after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “ Transaction Fees ”), shall constitute the net proceeds to the Company for such Offered Shares (the “ Net Proceeds ”).

(vi) A Manager shall provide written confirmation (which may be by facsimile or electronic mail) to the Company following the close of trading on the NYSE each day in which the Offered Shares are sold under this Section 3(a) setting forth the number of the Offered Shares sold by such Manager on such day, the aggregate gross sales proceeds and the Net Proceeds to the Company, and the compensation payable by the Company to such Manager with respect to such sales. Such compensation shall be set forth and invoiced in periodic statements from such Manager to the Company, with payment to be made by the Company promptly after its receipt thereof.

(vii) Settlement for sales of the Offered Shares pursuant to this Section 3(a) will occur on the third Business Day following the date on which such sales are made (or such earlier day as is industry practice for regular-way trading), or on some other date that is agreed upon by the Company and the Manager in connection with a particular transaction (each such day, a “ Settlement Date ”). On each Settlement Date, the Offered 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 aggregate gross sales proceeds less any Transaction Fees for the sale of such Offered Shares. Settlement for all such Offered Shares shall be effected by free delivery of the Offered Shares to such Manager’s account at The Depository Trust Company (“ 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 Offered Shares on any Settlement Date, the Company shall (A) indemnify and hold such Manager, as applicable, 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 compensation to which it would otherwise be entitled absent such default. If such Manager breaches this Agreement by failing to deliver the aggregate gross sales proceeds less any Transaction Fees to the Company on any Settlement Date for the Offered Shares delivered by the Company to such Manager, such breaching Manager will pay the Company an amount based on the effective overnight federal funds rate on such unpaid amount less any compensation due to such Manager.

(viii) At each Applicable Time, Settlement Date and Representation Date (as defined in Section 4(k ) of this Agreement), the Company shall be deemed to have affirmed each representation and warranty contained in Section 2 of this Agreement as if such representation and warranty were made as of such date, but modified as necessary to relate to the Registration Statement and the Prospectus and the documents incorporated by reference therein, in each case as amended or supplemented as of such date. Any obligation of any Manager to use its reasonable efforts to sell the Offered Shares on behalf of the Company shall be subject to the continuing accuracy of the representations and warranties of the Company herein (as modified in the manner describe above), 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 Offered Shares pursuant to this Agreement but 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. The terms set forth in a Terms

Agreement will not be binding on the Company or such Manager unless and until the Company and such Manager have each executed such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control to the extent of such conflict only.

(c) Each sale of the Offered Shares to any Manager shall be made in accordance with the terms of this Agreement and, if applicable, a Terms Agreement, which will provide for the sale of such Offered Shares to, and the purchase thereof by, such Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Offered Shares by a Manager. The commitment of a Manager to purchase the Offered Shares pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Offered Shares herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Offered Shares to be purchased by such Manager pursuant thereto, the price to be paid to the Company for such Offered Shares, any provisions relating to rights of, and default by, underwriters acting together with such Manager in the reoffering of the Offered Shares, and the time and date (each such time and date being referred to herein as a “ Time of Delivery ”) and place of delivery of and payment for such Offered Shares. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 6 of this Agreement and any other information or documents required by such Manager.

(d) Under no circumstances shall the number and aggregate amount of the Offered Shares sold pursuant to this Agreement and any Terms Agreement exceed (i) the aggregate amount set forth in Section 1 of this Agreement, (ii) the number of shares of Common Stock available for issuance under the currently effective Registration Statement or (iii) the maximum number and aggregate amount, if any, of the Offered Shares authorized from time to time to be issued and sold under this Agreement by the Board, or a duly authorized committee thereof, and notified to the Managers in writing.

(e) If any party hereto 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 Offered Shares, it shall promptly notify the other parties and sales of the Offered Shares under this Agreement and any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(f) Notwithstanding any other provision of this Agreement, the Company shall not request the sale of any Offered Shares that would be sold, and the Managers shall not be obligated to sell, during any period in which the Company is in possession of material non-public information.

(a) During any period when the delivery of a prospectus relating to the Offered Shares is required (including in circumstances where such requirement may be satisfied

pursuant to Rule 172) to be delivered under the Act, the Company will not file any (i) amendment to the Registration Statement, (ii) or supplement (including the Prospectus Supplement or any Interim Prospectus Supplement) to the Base Prospectus, or (iii) any Rule 462(b) Registration Statement relating to the Offered Shares (other than, in the case of clauses (i) and (ii) above, any amendment or supplement which does not relate to the sale of the shares of Common Stock and not including any reports or documents and any preliminary or definitive proxy or information statement required to be filed by the Company with the Commission in order to comply with the Exchange Act), unless the Company has furnished to the Managers a copy for its review prior to filing, and will not file any such proposed amendment or supplement or Rule 462(b) Registration Statement to which any Manager reasonably objects, unless (i) in the judgment of counsel to the Company, such amendment, supplement or filing is required by applicable law or (ii) is advisable in furtherance of a Commission request. The Company has properly completed the Prospectus, in a form approved by the Managers, and filed such Prospectus, as amended at the Execution Time, with the Commission pursuant to the applicable paragraph of Rule 424(b) by the Execution Time and will cause any supplement to the Prospectus to be properly completed, in a form approved by the Managers, and will file such supplement with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed thereby and will provide evidence satisfactory to the Managers of such timely filing. The Company will promptly advise the Managers (v) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement relating to the shares of Common Stock shall have been filed with the Commission, (w) when, during any period when the delivery of a prospectus (whether physically or through compliance with Rule 172 or any similar rule) is required under the Act in connection with the offering or sale of the Offered Shares, any amendment to the Registration Statement shall have been filed or become effective, (x) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement relating to the Company’s Common Stock, or for any supplement to the Prospectus or for any additional information, (y) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (z) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Shares for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its commercially reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to promptly use its commercially reasonable efforts to obtain the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its commercially reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If, at any time on or after an Applicable Time but prior to the related Settlement Date or Time of Delivery, any event occurs as a result of which the Disclosure Package would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Company will (i) notify promptly the Managers so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) other than during such time as when the offering of Offered Shares has been suspended pursuant to Section 3(a)(iii) of this Agreement, amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Managers in such quantities as the Managers may reasonably request.

(c) Other than during such time as when the offering of Offered Shares has been suspended pursuant to Section 3(a)(iii) of this Agreement, during any period when the delivery of a prospectus relating to the Offered Shares is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Act, any event occurs as a result of which the Prospectus as then supplemented would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Prospectus, the Company promptly will (i) promptly notify the Managers of any such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 4, an amendment or supplement or new registration statement that will correct such statement or omission or effect such compliance, (iii) use its commercially reasonable efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus and (iv) supply any supplemented Prospectus to the Managers in such quantities as the Managers may reasonably request.

(b) The Company shall have requested and caused Fried Frank to furnish to the Managers (or, in the case of a Representation Date of the type described in Section 4(k)(iii) of this Agreement, the relevant Manager party to such Terms Agreement), on every date specified in Section 4(l) of this Agreement, its opinion, dated as of such date and addressed to the Managers, in substantially the form set forth in Exhibit A hereto.

(f) The Company shall have furnished or caused to be furnished to the Managers (or, in the case of a Representation Date of the type described in Section 4(k)(iii) of this Agreement, the relevant Manager party to such Terms Agreement), on every date specified in Section 4(k) of this Agreement, a certificate of the Company, signed by the President and Chief Executive Officer and the principal financial or accounting officer of the Company, dated as of such date, to the effect that the signers of such certificate have reviewed the Registration Statement, the Disclosure Package and the Prospectus and any supplements or amendments thereto and this Agreement and that:

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Managers and counsel for the Managers, this Agreement and all obligations of the Managers hereunder may be canceled at, or at any time prior to, any Settlement Date or Time of Delivery, as applicable, by the Managers. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of Shearman & Sterling, counsel for the Managers, at 599 Lexington Avenue, New York, New York 10022, on each such date as provided in this Agreement.

(a) The Company agrees to indemnify and hold harmless each Manager, the directors, officers, employees, agents of each Manager, affiliates of each Manager and each person who controls any Manager within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arising out of or based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or in any amendment thereof or supplemental thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) an untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, the Prospectus Supplement, any Interim Prospectus Supplement, the Prospectus, or any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided , however , that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by any Manager or by legal counsel to the Managers on behalf of any Manager specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have. The Company acknowledges that the names of the Managers set forth in the first paragraph under the heading “Plan of Distribution” in the Prospectus constitute the only information furnished in writing by or on behalf of the several Managers for inclusion in the Prospectus.

(b) The Managers, severally and not jointly, agree to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement and each person who controls the Company within the meaning of either the Act or the Exchange Act to the same extent as the foregoing indemnity from the Company to the Managers, but only with reference to written information relating to such Manager furnished to the Company by such Manager or by legal counsel to the Managers on behalf of such Manager specifically for inclusion in the documents referred to in the foregoing indemnity, it being understood and agreed that the only such written information furnished by or on behalf of any of the Managers consists of the information described as such in Section 7(a) hereof. This indemnity agreement will be in addition to any liability which such Manager may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7 , notify the indemnifying party in writing of the commencement thereof; provided that the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and only to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above, as applicable. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided , however , that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (w) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (x) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (y) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (z) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless (i) such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Managers, severally and not jointly, agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “ Losses ”) to which the Company and the Managers, as applicable, may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the applicable Managers on the other from the offering of the Offered Shares; provided , however , that in no case shall any Manager be responsible for any amount in excess of the total compensation as set forth in Section 3(a)(v) of this Agreement, as the case may be, applicable to the Offered Shares purchased by such Manager hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the applicable Managers severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the applicable Managers on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by any Manager shall be deemed to be equal to the total compensation as set forth in Section 3(a)(v) of this Agreement, in each case as determined by this Agreement or any applicable Terms Agreement. Relative fault shall be determined by reference to, among other things, whether an untrue or an alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the applicable Manager on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Managers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), 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. For purposes of this Section 7 , each person who controls any Manager within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of any Manager shall have the same rights to contribution as the applicable Manager, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

(a) The Company shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement, with respect to any or all of the Managers, relating to the solicitation of offers to purchase the Offered 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 Offered Shares have been sold through any Manager for the Company, then Section 4(s) of this Agreement 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 the Managers, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Sections 2 , 5 , 7 , 9 , 10 , 12 and 14 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) Each Manager shall have the right, by giving written notice as hereinafter specified, to terminate its own obligations pursuant to the provisions of this Agreement relating to the solicitation of offers to purchase the Offered Shares in its sole discretion at any time. Any such termination shall have no effect on the obligations of any other Manager under this Agreement and shall be without liability of any party to any other party except that the provisions of Sections 2 , 5 , 7 , 9 and 14 of this Agreement shall remain in full force and effect with respect to such Manager notwithstanding such termination.

(c) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 8(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 Sections 2 , 5 , 7 and 9 shall remain in full force and effect.

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

(e) In the case of any purchase of Offered Shares by any Manager pursuant to a Terms Agreement, the obligations of such Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of such Manager, by notice given to the Company prior to the Time of Delivery relating to such Offered Shares, if at any time prior to such delivery and payment (i) trading in the Company’s Common Stock shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE or NASDAQ shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of such Manager, impractical or inadvisable to proceed with the offering or delivery of the Offered Shares as contemplated by the Prospectus (exclusive of any amendment or supplement thereto).

9. Representations and Indemnities to Survive . The respective agreements, representations, warranties, indemnities and other statements of the Company or its respective officers and of each Manager set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by any Manager or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Offered Shares.

12. No Fiduciary Duty . The Company hereby acknowledges that (a) the purchase and sale of the Offered Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and each of the Managers and any affiliate through which it may be acting, on the other hand, (b) each Manager is acting solely as sales agent and/or principal in connection with the purchase and sale of the Company’s Common Stock and not as a fiduciary of the Company and (c) the Company’s engagement of the Managers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any Manager has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that any Manager has rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

13. Integration . This Agreement and any Terms Agreement supersede all prior agreements and understandings (whether written or oral) between the Company and any Manager with respect to the subject matter hereof.

14. Applicable Law .
