The respective principal amounts of the Notes to be so purchased, severally and not jointly, by the several Underwriters are set forth opposite their names in Exhibit A hereto. The Notes will be unconditionally guaranteed (the “Guarantees” and, together with the Notes, the “Securities”) by CubeSmart, a Maryland real estate investment trust (the “Company” and together with the Operating Partnership, the “Transaction Entities”), and the sole general partner and a limited partner of the Operating Partnership. The Securities are to be issued pursuant to an indenture dated as of September 16, 2011 (the “Base Indenture”) as amended and supplemented by the Second Supplemental Indenture thereto dated December 17, 2013, with respect to the 2023 Notes, by the Third Supplemental Indenture thereto dated as of October 26, 2015, with respect to the 2025 Notes, and by a Fifth Supplemental Indenture (the “Fifth Supplemental Indenture”), with respect to the Notes, among the Operating Partnership, the Company and U.S. Bank National Association, as trustee (the “Trustee”), thereto to be entered into as of Closing with respect to the notes of each series offered hereby. The Base Indenture, as supplemented with respect to each series of Notes as applicable, are referred to collectively as the ‘‘Indenture’’. Certain terms used in this Agreement are defined in Section 15 hereof.

The Transaction Entities understand that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Transaction Entities have prepared and previously delivered to you a preliminary prospectus supplement dated March 30, 2017 relating to the Securities and a related base prospectus dated March 17, 2017 (the “Base Prospectus”). Such preliminary prospectus supplement and Base Prospectus, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are hereinafter called, collectively, the “Pre-Pricing Prospectus.” Promptly after the execution and delivery of this Agreement, the Company will prepare and file with the Commission a prospectus supplement dated March 30, 2017 (the “Prospectus Supplement”) together with the Base Prospectus, all in accordance with the provisions of Rule 430B and Rule 424(b). The Prospectus Supplement and the Base Prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Securities (whether to meet the requests of purchasers pursuant to Rule 173(d) or otherwise), including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are herein called, collectively, the “Prospectus.”

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Transaction Entities. The Transaction Entities hereby jointly and severally represent and warrant to each Underwriter as of the date hereof, as of the Applicable Time and as of the Closing Date referred to in Section 2(b) hereof and agree with each Underwriter, as follows:

(1) Status as a Well-Known Seasoned Issuer. (A) At the respective times the Registration Statement or any amendments thereto were filed with the Commission, (B) at the time of the most recent amendment to the Registration Statement for the purposes of complying with Section 10(a)(3) of the 1933 Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the 1934 Act or form of prospectus), (C) at any time the Transaction Entities or any person acting on their behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption of Rule 163 and (D) at the date hereof, the Company was and is a “well-known seasoned issuer” as defined in Rule 405, including not having been and not being an “ineligible issuer” as defined in Rule 405 (without taking into account any determination made by the Commission pursuant to paragraph (2) of the definition of such term in Rule 405). The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 and the Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Transaction Entities on such an “automatic shelf registration statement.” The Transaction Entities have not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to the use of the automatic shelf registration statement form. Any written communication that was an offer relating to the Securities made by the Transaction Entities or any person acting on their behalf (within the meaning, for this sentence only, of Rule 163(c)) prior to the filing

of the Registration Statement has been filed with the Commission in accordance with Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

(2) Compliance with Registration Requirements. The Transaction Entities meet the requirements for use of Form S-3 under the 1933 Act and the Securities have been duly registered under the 1933 Act pursuant to the Registration Statement. The Registration Statement and any post-effective amendments thereto have become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Transaction Entities, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. The Registration Statement was initially filed with the Commission on March 17, 2017.

(3) Registration Statement, Prospectus and Disclosure at Time of Sale. At the respective times that the Registration Statement and any amendments thereto became effective, at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2), and at the Closing Date, the Registration Statement and any amendments to the Registration Statement complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

At the respective times that the Prospectus or any amendment or supplement thereto was filed pursuant to Rule 424(b) or issued, at the Closing Date, and at any time when a prospectus is required (or, but for the provisions of Rule 172, would be required) by applicable law to be delivered in connection with sales of Securities (whether to meet the requests of purchasers pursuant to Rule 173(d) or otherwise), neither the Prospectus nor any amendments or supplements thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Each preliminary prospectus and the Prospectus and any amendments or supplements to any of the foregoing filed as part of the Registration Statement or any amendment thereto, or

filed pursuant to Rule 424 under the 1933 Act, or delivered to the Underwriters for use in connection with the offering of the Securities, complied when so filed or when so delivered, as the case may be, in all material respects with the 1933 Act and the 1933 Act Regulations.

The representations and warranties in the preceding paragraphs of this Section 1(a)(3) do not apply to statements in or omissions from the Registration Statement, any preliminary prospectus, the Prospectus, the General Disclosure Package or any Issuer Free Writing Prospectus or any amendment or supplement to any of the foregoing made in reliance upon and in conformity with the Underwriter Content (as hereinafter defined).

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offering and sale of the Securities did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any preliminary prospectus (including the Pre-Pricing Prospectus) or the Prospectus that has not been superseded or modified.

At the respective times that the Registration Statement or any amendments to any of the foregoing were filed and as of the earliest time after the filing of the Registration Statement that either of the Transaction Entities or any other offering participant made a bona fide offer of the Securities within the meaning of Rule 164(h)(2), and at the date hereof, neither of the Transaction Entities was nor is an “ineligible issuer” as defined in Rule 405, in each case without taking into account any determination made by the Commission pursuant to paragraph (2) of the definition of such term in Rule 405; and without limitation to the foregoing, each of the Transaction Entities has at all relevant times met, meets and will at all relevant times meet the requirements of Rule 164 for the use of a free writing prospectus (as defined in Rule 405) in connection with the offering contemplated hereby.

(22) No Material Actions or Proceedings. Except as otherwise disclosed in the General Disclosure Package and the Prospectus, there are no legal or governmental actions, suits or proceedings pending or, to the Company’s knowledge, threatened against or affecting the Transaction Entities or any of their subsidiaries, (i) which has as the subject thereof any officer, director or trustee of, or property owned or leased by, the Transaction Entities or any of their subsidiaries or (ii) relating to environmental or discrimination matters, where in either such case, (A) there is a reasonable possibility that such action, suit or proceeding might be determined adversely to such Transaction Entity or subsidiary, or any officer, director or trustee of, or property owned or leased by, the Transaction Entities or any of their subsidiaries and (B) any such action, suit or proceeding, if so determined adversely, could reasonably be expected to have a Material Adverse Effect or adversely affect the consummation of the transactions contemplated by this Agreement, the Securities or the Indenture.

(l) Compliance with ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. The Transaction Entities will comply in all material respects with all applicable securities and other laws, rules and regulations, including, without limitation, the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, and use their best efforts to cause the Company’s trustees and Transaction Entities’ officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act.

deemed furnished to the Representatives and Underwriters in satisfaction of the Transaction Entities’ obligations under this paragraph.

(o) REIT Qualification. The Company will use its best efforts to continue to meet the requirements for qualification and taxation as a REIT under the Code, subject to any future determination by the Company’s board of trustees that it is no longer in the Company’s best interests to qualify as a REIT.

(p) Investment Limitation. The Transaction Entities shall not invest, or otherwise use the proceeds received by the Transaction Entities from their sale of the Securities in such a manner as would require the Transaction Entities or any of their subsidiaries to register as an investment company under the 1940 Act.

SECTION 5. Conditions of Underwriters’ Obligations. The obligations of the several Underwriters hereunder are subject to the accuracy of the representations and warranties of the Transaction Entities contained in this Agreement, or in certificates signed by any officer of the Company or the Operating Partnership or any subsidiary of the Company or the Operating Partnership (whether signed on behalf of such officer, the Company, the Operating Partnership or such subsidiary) delivered to the Representatives or counsel for the Underwriters, to the performance by the Transaction Entities of their respective covenants and other obligations hereunder, and to the following further conditions:

SECTION 6. Indemnification.

(a) Indemnification by the Transaction Entities. The Transaction Entities, jointly and severally, agree to indemnify and hold harmless each Underwriter, its affiliates, and its and their officers, directors, employees, partners and members and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement to any of the foregoing), or any “issuer information” (as defined in Rule 433) filed or required to be filed pursuant to Rule 433(d), or any “road show” (as defined in Rule 433) that does not constitute an Issuer Free Writing Prospectus or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Transaction Entities; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above,

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with the Underwriter Content (defined below in Section 6(b)).

(b) Indemnification by the Underwriters. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Transaction Entities, the Company’s directors and/or trustees, each of the Transaction Entities’ officers who signed the Registration Statement and each person, if any, who controls either of the Transaction Entities within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), in any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement to any of the foregoing), or any “issuer information” (as defined in Rule 433) filed or required to be filed pursuant to Rule 433(d), in reliance upon and in conformity with the Underwriter Content. The Transaction Entities hereby acknowledge and agree that the only information furnished to the Transaction Entities by the Underwriters through the Representatives expressly for use in the Registration Statement (or any amendment thereto), in any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement to any of the foregoing), or any “issuer information” (as defined in Rule 433) filed or required to be filed pursuant to Rule 433(d), consists exclusively of the following information appearing under the caption “Underwriting (Conflicts of Interest)” in the Pre-Pricing Prospectus and the Prospectus: (i) the information in the chart in the first paragraph, (ii) the first paragraph under the subcaption “Discounts” and (iii) the first and second paragraphs under the subcaption “Price Stabilization and Short Positions (the “Underwriter Content”).

(c) Actions Against Parties; Notification. In case any action, investigation or proceeding (including any investigation or proceeding by any governmental agency or body) shall be commenced involving any party or parties in respect of which indemnity may be sought pursuant to this Section 6, such party or parties (the “indemnified party” or the “indemnified parties”) shall give notice as promptly as reasonably practicable to the party or parties against whom such indemnity may be sought (the “indemnifying party” or the “indemnifying parties”) of such action, investigation or proceeding, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder, except to the extent that it has been materially prejudiced through the forfeiture of substantive rights or defenses by such failure. Counsel to the indemnified parties shall be selected as follows: counsel to the Underwriters and the other indemnified parties referred to in Section 6(a) above shall be selected by the Representatives; and counsel to the Transaction Entities, the Company’s directors and/or trustees, each officer who signed the Registration Statement, and each person, if any, who controls either of the Transaction Entities within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall be selected by the Transaction Entities. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly and with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified person, to assume the defense thereof; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Underwriters and the other indemnified parties referred to in Section 6(a) above, and the fees and expenses of more than one counsel (in

addition to any local counsel) separate from their own counsel for the Transaction Entities, the Company’s directors and/or trustees, each officer who signed the Registration Statement and each person, if any, who controls either of the Transaction Entities within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim 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) Settlement Without Consent if Failure to Reimburse. 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 this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Transaction Entities on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Transaction Entities on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Transaction Entities on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Transaction Entities and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Transaction Entities on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Transaction Entities on the one hand or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Transaction Entities and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each officer, director, employee, partner and member of any Underwriter and its affiliates and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director and/or trustee of the Company, each officer of the Transaction Entities who signed the Registration Statement, and each person, if any, who controls either of the Transaction Entities within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Transaction Entities. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the aggregate principal amount of Securities set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates signed by any officer of the Transaction Entities or any of their subsidiaries (whether signed on behalf of such officer, the Transaction Entities or such subsidiary) and delivered to the Representatives or counsel to the Underwriters, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer, director, employee, partner, member or agent of any Underwriter or any person controlling any Underwriter, or by or on behalf of the Transaction Entities, any officer, director, trustee or employee of the Transaction

Entities or any person controlling either of the Transaction Entities, and shall survive delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Transaction Entities, at any time on or prior to the Closing Date (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Prospectus (in each case exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), any Material Adverse Change or any development that could reasonably expected to result in a Material Adverse Change, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any declaration of a national emergency or war by the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions (including, without limitation, as a result of terrorist activities), in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE, or if trading generally on the NYSE, the Nasdaq Global Select Market, the Nasdaq Global Market, the NYSE MKT, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or in Europe, or (iv) if a banking moratorium has been declared by either Federal or New York authorities or (v) if there shall have occurred, since the time of execution of this Agreement, any downgrading in the rating of any debt securities or Preferred Shares of the Company, or of the securities of any subsidiary or subsidiary trust of the Company, by any “nationally recognized statistical rating organization” (as defined by the Commission for purposes of Section 3(a)(62) of the ▇▇▇▇ ▇▇▇) or any public announcement that any such organization has placed its rating on the Company or any such debt securities or Preferred Shares under surveillance or review or on a so-called “watch list” (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any announcement by any such organization that either of the Transaction Entities or any such debt securities or Preferred Shares has been placed on negative outlook.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, and 11 through 20 hereof shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Date to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the

non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

(ii) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, the Representatives shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Notices. All notices and other communications hereunder shall be in writing, shall be effective only upon receipt and shall be mailed, delivered by hand or overnight courier, or transmitted by fax (with the receipt of any such fax to be confirmed by telephone).
