3. Sale and Delivery of Offered Shares .

(a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to issue and sell Offered Shares from time to time through one or more of the Managers, acting as sales agents, and each Manager agrees, severally and not jointly, to use its commercially reasonable efforts to sell, as sales agent for the Company, the Offered Shares on the following terms.

(i) The Offered Shares are to be sold on a daily basis or otherwise as shall be agreed to by the Company and any Manager on any day that (A) is a trading day for the New York Stock Exchange (“ NYSE ”), (B) the Company, through any of the individuals listed as Authorized Representatives on

12

Schedule II hereto, which Schedule II may be updated by the Company or its counsel from time to time by written notice delivered to the Managers or their counsel, has instructed such 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. The Company will designate the maximum amount of the Offered Shares to be sold by such 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, such Manager shall use its commercially reasonable efforts to sell on a particular day all of the Offered Shares designated for 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 Common Shares sold by such Manager under this Section 3(a) on the NYSE at the time of sale of such Offered Shares. For the avoidance of doubt, the Company shall submit instructions to sell Offered Shares to only one Manager, if any, on any single trading day.

(ii) The Company acknowledges and agrees that (A) there can be no assurance that any Manager will be successful in selling the Offered Shares, (B) no Manager will incur any liability or obligation to the Company or any other person or entity if such Manager does not sell Offered 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 Offered Shares as required under this Agreement and (C) no Manager shall be under any obligation to purchase Offered Shares on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by such Manager and the Company in writing pursuant to a Terms Agreement.

(iii) The Company shall not authorize the issuance and sale of, and no Manager shall be obligated to use its commercially reasonable efforts to sell, any Offered Shares at a price lower than the minimum price therefor designated from time to time by the Company’s Board of Directors (the “ Board ”), or a pricing committee duly authorized thereby, and notified to such Manager in writing, or in a number in excess of the number of shares of Common Shares approved for listing on the NYSE. The Company, through any Authorized Representative, or any Manager may, upon notice to the other party hereto 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.

13

(iv) Each Manager hereby covenants and agrees, severally and not jointly, not to make any sales of the Offered Shares on behalf of the Company, pursuant to this Section 3(a), other than (A) by means of ordinary brokers’ transactions between members of the NYSE (or any other national securities exchange or quotation service on which the Offered Shares may be listed or quoted at the time of sale) that meet the conditions set forth in Rule 153 that the parties hereto agree shall not constitute a “distribution” within the meaning of Rule 100 under Regulation M 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 2.0% of the gross sales price of the Offered Shares sold 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 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) Each 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 on which the Offered Shares are sold under this Section 3(a) setting forth the number of the Offered Shares sold 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, if not previously made.

(vii) Settlement for sales of the Offered Shares pursuant to this Section 3(a) will occur on the second Business Day following the date on which such sales are made, or on such 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 any 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 harmless against any loss, claim or damage arising from or as a result of such default by the Company and (B) pay such

14

Manager any commission to which it would otherwise be entitled absent such default. If any 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, such Manager will pay the Company interest based on the effective overnight federal funds rate on such unpaid amount less any compensation to which such Manager is entitled.

(viii) At each Applicable Time, Settlement Date and Representation Date (as defined in Section 4(k)) with respect to each of which the Company is obligated to deliver a certificate pursuant to Section 6(f) hereof, the Company shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date, 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 and to reflect such necessary modifications as are not material and approved by the Managers in advance. Any obligation of any Manager to use its commercially 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, 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 the Managers of the proposed terms of such Placement. If any Manager, each 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(s) 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(s) unless and until the Company and such Manager(s) 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 such Manager. The commitment of any 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 Company herein contained and shall be subject to the terms and conditions herein set forth and, if applicable, a Terms Agreement. 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.

15

(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 Offered Shares 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.

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 file promptly 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 Disclosure Package and for so long as the delivery of a prospectus relating to the Offered 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 Managers (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when

16

any Rule 462(b) Registration Statement relating to the Common Shares shall have been filed with the Commission, (ii) 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 Securities 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, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Prospectus or for any additional information, (iv) 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 or pursuant to Section 8A of the Securities Act and (v) 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 best 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 obtain as soon as possible 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 best 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 in order to make the statements therein, in the light of the circumstances under which they were made or the circumstances then prevailing, 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 Securities Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Prospectus, 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 or effect such compliance; 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 or any similar rule) to be delivered under the Securities 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 in order to make the statements therein, in the light of the circumstances under which they were made at such time, 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 Securities 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) notify the Managers of any such event, (ii) prepare and file with the Commission, subject to the first

17

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 best 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.

(d) As soon as practicable after the Effective Date and in any event not later than 16 months after the date hereof, the Company will make generally available via the Commission’s Electronic Data Gathering, Analysis, and Retrieval (EDGAR) System, to the Company’s security holders and to the Managers, an earnings statement of the Company and its subsidiaries (which need not be audited) complying with Section 11(a) of the Securities Act and the rules and regulations promulgated thereunder (including, at the option of the Company, Rule 158).

(e) The Company will furnish or otherwise make available upon request to the Managers and counsel for the Managers, without charge, as many copies of the Registration Statement (including exhibits thereto), the Prospectus and each Issuer Free Writing Prospectus and any supplement thereto and any documents incorporated by reference therein as the Managers may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering.

(f) The Company will promptly from time to time take such action as the Managers may reasonably request to qualify the Offered Shares for offering and sale under the securities laws of such jurisdictions as the Managers may request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Offered Shares; provided that in connection therewith the Company shall not be required to (i) qualify as a foreign corporation in any jurisdiction in which it would not otherwise be required to so qualify, (ii) file a general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any jurisdiction in which it would not otherwise be subject.

(g) The Company agrees that, unless it has or shall have obtained the prior written consent of the Managers, and each Manager agrees with the Company that, unless it has or shall have obtained, as the case may be, the prior written consent of the Company, each such party has not made and will not make any offer relating to the Offered Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule I hereto. Any such free writing prospectus consented to by the Managers or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (ii) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

25

(h) At any time that sales of the Offered Shares have been made but not settled or at any time the Company has outstanding with any Manager any instructions to sell Offered Shares but such instructions have not been fulfilled or cancelled, no downgrading shall have occurred in the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization” (as that term is defined under Section 3(a)(62) of the Exchange Act).

7. Indemnification and Contribution .

(a) The Company shall indemnify and hold harmless each Manager, its directors, officers, employees, agents, affiliates and each person, if any, who controls any Manager within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Offered Shares), to which that Manager, director, officer, employee, agent, affiliate or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) an untrue statement or alleged untrue statement of a material fact contained in (A) the Base Prospectus, any Prospectus Supplement, the Registration Statement or the Prospectus (in the case of the Base Prospectus, any Prospectus Supplement or the Prospectus, in the light of the circumstances under which any such statements were made) or in any amendment or supplement thereto or (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, in the light of the circumstances under which any such statements were made, or (ii) the omission or alleged omission to state in the Base Prospectus, any Prospectus Supplement, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, a material fact required to be stated therein (in the case of the Registration Statement) or necessary to make the statements therein not misleading (in the case of the Base Prospectus, any Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus, in the light of the circumstances under which any such statements were made), and shall reimburse each Manager and each such director, officer, employee, agent, affiliate or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Manager, director, officer, employee, agent, affiliate or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided , however , that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, an untrue statement or alleged untrue statement or omission or alleged omission made in the Base Prospectus, any Prospectus Supplement, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto, in reliance upon and in conformity with written information concerning such Manager furnished to the Company by or on behalf of any Manager specifically for inclusion therein, which information consists solely of the information specified in Section 7(e). The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Manager or to any director, officer, employee, agent, affiliate or controlling person of that Manager.

(b) Each Manager, severally and not jointly, shall indemnify and hold harmless the Company, its directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), managers, officers, employees, agents and affiliates, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or

27

liability, joint or several, or any action in respect thereof, to which the Company or any such director, manager, officer, employee, agent, affiliate or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) an untrue statement or alleged untrue statement of a material fact contained in (A) the Base Prospectus, any Prospectus Supplement, the Registration Statement or the Prospectus (in the case of the Base Prospectus, any Prospectus Supplement or the Prospectus, in the light of the circumstances under which any such statements were made) or in any amendment or supplement thereto or (B) any Issuer Free Writing Prospectus or in any amendment thereof or supplement thereto, in the light of the circumstances under which any such statements were made, or (ii) the omission or alleged omission to state in the Base Prospectus, any Prospectus Supplement, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment thereof or supplement thereto, a material fact required to be stated therein (in the case of the Registration Statement) or necessary to make the statements therein not misleading (in the case of the Base Prospectus, any Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus, in the light of the circumstances under which any such statements were made), but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Manager furnished to the Company by or on behalf of that Manager specifically for inclusion therein, which information is limited to the information set forth in Section 7(e). The foregoing indemnity agreement is in addition to any liability that any Manager may otherwise have to any of the Company or any such director, manager, officer, employee, agent, affiliate or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of any claim or the commencement of any action, the indemnified party shall, 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 claim or the commencement of that action; provided , however , that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under Sections 7(a) and 7(b) except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure; provided further that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under Sections 7(a) and 7(b). If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided , however , that the indemnified party shall have the right to employ separate counsel and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such

28

proceeding (including any impleaded parties) include both the indemnified party on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would present such counsel with a conflict of interest. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 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 does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 7 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or 7(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Managers, on the other, from the offering of the Offered 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 the Managers, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Managers, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Offered Shares purchased under this Agreement (before deducting expenses) received by the Company, as determined by this Agreement or any applicable Terms Agreement, on the one hand, and the total discounts and commissions received by the Managers with respect to the Offered Shares purchased under this Agreement, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Managers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Managers agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation (even if the Managers were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 7(d) shall be deemed to include, for purposes of this Section 7(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or

29

defending any such action or claim. Notwithstanding the provisions of this Section 7(d), no Manager shall be required to contribute any amount in excess of the discount or commission applicable to the Offered Shares purchased by such Manager hereunder. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Managers’ obligations to contribute as provided in this Section 7(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Managers severally confirm and the Company acknowledges that the only information concerning such Managers furnished in writing to the Company by the Managers specifically for inclusion in the Registration Statement, the Base Prospectus, any Prospectus Supplement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto consists of the name and contact information of such Managers.

8. Termination .

(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 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) the Managers shall be entitled to any commissions earned in accordance with Section 3(a)(v) hereof, (ii) if at the time of termination (a) a Manager shall own any Offered Shares purchased by it as principal or (b) an offer to purchase any Offered Shares has been accepted by the Company but the Settlement Date has not occurred, the covenants set forth in Section 4 hereof shall remain in effect until such Offered Shares are resold or so delivered, as the case may be and (iii) the provisions of Sections 2, 5, 7, 9, 10, 11, 12, 13, 14, 16 and 17 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 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 be without liability of any party to any other party except that the provisions of Sections 2, 4(d), 5, 7, 9, 10, 11, 12, 13, 14, 16 and 17 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 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 any 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.

9. Representations and Indemnities to Survive . The respective agreements, representations, warranties, indemnities and other statements of the Company or its 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 the Managers or the Company or any of the officers, directors, employees, agents, affiliates or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Offered Shares.

10. Research Analyst Independence . The Company acknowledges that the Managers’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Managers’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering of the Offered Shares that differ from the views of their respective investment bankers. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Managers with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Managers’ investment banking divisions. The Company acknowledges that each of the Managers is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the Company.

11. No Fiduciary Duty . The Company acknowledges and agrees that in connection with the offering of the Offered Shares, the sale of the Offered Shares or any other services the Managers may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Managers: (i) no fiduciary relationship between the Company and any other person, on the one hand, and the Managers, on the other, exists; (ii) the Managers are not acting as advisors, expert or otherwise, to the Company, and such relationship between the Company, on the one hand, and the Managers, on the other, is entirely and solely commercial, based on arm’s-length negotiations; (iii) any duties and obligations that the Managers may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Managers and their respective affiliates may have interests that differ from those of the Company. Furthermore, the Company agrees that it is solely responsible for making its own judgments and decisions in connection with this offering. The Company hereby waives any claims that it may have against the Managers with respect to any breach of fiduciary duty in connection with this offering.

12. USA Patriot Act . In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Managers are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of the Managers’ respective clients, as well as other information that will allow the Managers to properly identify their respective clients.
