In addition, the Company has agreed to sell to the Underwriters, upon the terms and conditions stated herein, up to an additional 1,200,000 Common Shares (the “Additional Shares”) to cover over-allotments by the Underwriters, if any. The Firm Shares and the Additional Shares are collectively referred to in this Agreement as the “Shares.” ▇▇▇▇▇▇ ▇. ▇▇▇▇▇ & Co. Incorporated and RBC Capital Markets Corporation, the joint book running managers, are acting as the representatives of the several Underwriters and in such capacity are referred to in this Agreement as the “Representatives.” The Company owns 100% of IRET, Inc., which is the sole general partner of IRET Properties, a North Dakota limited partnership that serves as the Company’s primary operating partnership subsidiary (the “Operating Partnership”). Certain terms used herein are defined in Section 20 hereof.

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Securities Act”), with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-153715), including a Base Prospectus, relating to certain securities, including the Shares, to be issued from time to time by the Company, and which incorporates by reference documents that the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”). Any reference herein to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be deemed to refer to and include the documents incorporated by reference therein (or deemed to be incorporated by reference therein), and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated by reference therein. For purposes of this Agreement, all references to the Registration Statement, the Prospectus or to any amendment or supplement thereto shall be deemed to include any copy filed with the Commission pursuant to either the Electronic Data Gathering Analysis and Retrieval System or Interactive Data Electronic Applications (collectively, “IDEA”).

The Company and the Operating Partnership jointly and severally represent and warrant to, and agree with, each Underwriter as of the date hereof, as of the Closing Date (defined below) and as of the Option Closing Date (defined below) as follows:

Each of the Company, the Operating Partnership and their Subsidiaries (as defined in Section 20 hereof) is duly organized and validly existing in good standing under the laws of the state of its incorporation or organization with full corporate, partnership or entity power and authority, as the case may be, to own, lease and operate its Properties (as defined below) and to conduct its business as presently conducted and as described in the Prospectus and is duly registered and qualified to conduct its business and is in good standing in each jurisdiction or place where the nature of its Properties or the conduct of its business requires such registration or qualification, except where the failure to so register or qualify (i) has not had or would not have, individually or in the aggregate, a material adverse effect on the earnings, business, Properties, assets, operations, condition (financial or otherwise) or prospects of the Company and its Subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, or (ii) would not prevent the consummation of the transactions contemplated hereby (the occurrence of any such effect or any such prevention described in the foregoing clauses (i) and (ii) being referred to as a “Material Adverse Effect”). The Company owns 100% of IRET, Inc., which is the sole general partner of the Operating Partnership. Except for the Subsidiaries and joint venture arrangements included on Schedule III or disclosed in the Prospectus, the Company does not own a material interest in or control, directly or indirectly, any other corporation, partnership, joint venture, association, trust or other business organization.

(g) Property. (1) The Company or its Subsidiaries have fee simple title or a valid leasehold interest to all of the properties described in the Prospectus as owned or leased by the Company or its Subsidiaries, whether owned in fee simple or through a joint venture or other partnership (the “Properties” or “Property”), in each case, free and clear of all liens, encumbrances, claims, security interests and defects, except such as (i) are disclosed in the Prospectus or (ii) could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; (2) neither the Company nor any Subsidiary thereof has received from any governmental authority any written notice of any condemnation of, or zoning change affecting any of, the Properties or any part thereof, and the Company does not know of any such condemnation or zoning change which is threatened, which if consummated could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect; (3) except as otherwise described in the Prospectus, neither the Company nor, to the knowledge of the Company, any tenant of any of the Properties is in default under (i) any space lease (as lessor or lessee, as the case may be) relating to any of the Properties (except such tenant defaults that would not, individually or in the aggregate, have a Material Adverse Effect), or (ii) any of the mortgages or other security documents or other agreements encumbering or otherwise recorded against the Properties, and the Company does not know of any event which, but for the passage of time or the giving of notice, or both, would constitute a default under any of such documents or agreements, except any such default that would not, individually or in the aggregate, have a Material Adverse Effect; and (4) except as disclosed in the Prospectus, no tenant under any of the leases at the Properties has a right of first refusal to purchase the premises demised under such lease. To the knowledge of the Company, water, stormwater, electricity and telephone service are all available at the property lines of each Property over duly dedicated streets or perpetual easements of record benefiting the applicable Property and each of the Properties is free of any material structural defects and all building systems contained therein are in reasonable working order in all material respects, subject to ordinary wear and tear or, in each instance, the Company or any Subsidiary, as the case may be, has created an adequate reserve or capital budget to effect reasonably required repairs, maintenance and capital expenditures.

(h) Leases. Each Property with respect to which the Company or one of the Subsidiaries has a leasehold interest is the subject of a lease that has been entered into by, or assigned to, the Company or a Subsidiary, as the case may be, and has been duly and validly authorized, executed and delivered by or on behalf of the Company or such Subsidiary, as the case may be, and constitutes a valid and binding agreement of the Company or such Subsidiary, as the case may be, enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally or by general principles of equity.

(i) Mortgage; Deed of Trusts. The mortgages and deeds of trust encumbering the Properties are not convertible into equity interests in the Property nor will the Company or the Operating Partnership hold a participating interest therein and such mortgages and deeds of trust are not cross-defaulted or cross-collateralized to any property not to be owned directly or indirectly by the Company or the Operating Partnership.

(j) Subsidiaries. The outstanding equity interests of each of the Company’s Subsidiaries have been duly authorized and validly issued, are fully paid and nonassessable and are owned by the Company or the Operating Partnership, directly or through Subsidiaries, free and clear of any security interests, liens, encumbrances, equities or claims.

(k) No Proceedings. Except as described in the Prospectus, there is no action, suit, inquiry, proceeding or investigation by or before any court or governmental or other regulatory or administrative agency

Neither the Company, the Operating Partnership, nor any of the Subsidiaries is (i) in violation of (A) its Organizational Documents, (B) to the Company’s knowledge, any law, ordinance, administrative or governmental rule or regulation applicable to the Company, the Operating Partnership, or any Subsidiary, the violation of which would have a Material Adverse Effect or (C) any decree of any court or governmental agency or body having jurisdiction over the Company or any of its Subsidiaries; or (ii) in default in any material respect in the performance of any obligation, agreement or condition contained in (A) any bond, debenture, note or any other evidence of indebtedness or (B) any agreement, indenture, lease or other instrument (each of (A) and (B), an “Existing Instrument”) to which the Company, the Operating Partnership, or any Subsidiary is a party or by which any of their Properties may be bound, which default would have a Material Adverse Effect; and, to the Company’s knowledge, there does not exist any state of facts that constitutes a default or an event of default on the part of the Company or any of its Subsidiaries as defined in such documents or that, with notice or lapse of time or both, would constitute such a default or event of default which would have a Material Adverse Effect.

bankruptcy, insolvency, reorganization or other laws of general applicability relating to or affecting creditors’ rights or by general equity principles.

(p) No Consent. No consent, approval, authorization, order, license, certificate, permit, registration, designation or filing by or with any governmental agency or body is required for the execution, delivery and performance by the Company and the Operating Partnership of their respective obligations under this Agreement and the consummation by the Company and the Operating Partnership of the transactions contemplated hereby, including the valid authorization, issuance, sale and delivery of the Shares, except such as may be required by the federal securities laws, the NASDAQ, the securities or Blue Sky laws of the various states and the Financial Industry Regulatory Association (“FINRA”) in connection with the offer and sale of the Shares, all of which will be, or have been obtained, in accordance with this Agreement.

(q) Non-Contravention of Existing Instruments. Neither the issuance and sale of the Shares by the Company, the execution, delivery or performance of this Agreement by the Company and the Operating Partnership nor the consummation by the Company and the Operating Partnership of the transactions contemplated hereby (i) conflicts with, or will conflict with, or constitutes, or with the giving of notice or lapse of time, will constitute a breach of, or a default under, the Company’s Declaration of Trust or bylaws (or other applicable Organizational Document), the Operating Partnership’s certificate of limited partnership or the Partnership Agreement, or any Existing Instrument to which the Company or any of its Subsidiaries is a party or by which any of its or their Properties may be bound, as the case may be, (ii) violates any statute, law, regulation, ruling, filing, judgment, injunction, order or decree applicable to the Company or any of its Subsidiaries or any of their Properties, or (iii) results in a breach of, or default or Debt Repayment Triggering Event (as defined below) under, or results in the creation or imposition of any lien, charge or encumbrance upon any Property or assets of the Company or any of its Subsidiaries pursuant to, or requires the consent of any other party to, any Existing Instrument, except for such conflicts, breaches, defaults, liens, charges or encumbrances that will not, individually or in the aggregate, result in a Material Adverse Effect. As used herein, a “Debt Repayment Triggering Event” means any event or condition that gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of its Subsidiaries.

(r) No Applicable Registration Rights.

Except as disclosed in the Prospectus (as amended or supplemented), all material deficiencies asserted as a result of any federal, state, local or foreign tax audits have been paid or finally settled and no issue has been raised in any such audit that, by application of the same or similar principles, reasonably could be expected to result in a proposed deficiency for any other period not so audited. There are no outstanding agreements or waivers extending the statutory period of limitation applicable to any federal, state, local or foreign tax return for any period.

(cc) Internal Controls and Procedures. The Company has established and maintains disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms and is accumulated and communicated to the Company’s management, including its chief executive officer and chief financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure; and the Company maintains a system of internal control over financial reporting sufficient to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and which includes policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP and that receipts and expenditures of the Company are being made only in accordance with the authorization of management, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use or dispositions of assets that could have a material effect on the Company’s consolidated financial statements. The Company’s disclosure controls and procedures have been evaluated for effectiveness as of the end of the period covered by the Company’s most recently filed quarterly report on Form 10-Q which precedes the date of the Prospectus and were effective in all material respects to perform the functions for which they were established. Based on the most recent evaluation of its internal control over financial reporting, the Company was not aware of (i) any material weaknesses in the design or operation of

internal control over financial reporting or (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting.

(dd) Unlawful Contributions or Payments. Neither the Company nor the Operating Partnership, nor to the Company’s or the Operating Partnership’s knowledge, any trustee, officer, agent, employee or other person associated with or acting on behalf of the Company or the Operating Partnership, has used any funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; made any direct or indirect unlawful payment to any foreign or domestic government official or employee from company funds; violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977; or made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment. No funds of the Company have been set aside to be used for any payment in violation of any law. Neither the Company, nor any of its Subsidiaries nor any trustee, officer, agent, or employee of the Company or any of its Subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of the offering contemplated by this Agreement, or lend, contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

(ee) Environmental Compliance. To the knowledge of the Company, the Company and its Subsidiaries are (i) in compliance with any and all applicable federal, state, local and foreign laws and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) have received all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are in compliance with all terms and conditions of any such permit, license or approval, except where such noncompliance with Environmental Laws, failure to receive required permits, licenses or other approvals or failure to comply with the terms and conditions of such permits, licenses or other approvals would not, individually or in the aggregate, have a Material Adverse Effect. To the knowledge of the Company, neither the Company nor any of its Subsidiaries has been named as a “potentially responsible party” under the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended (“CERCLA”). The Properties are not included or, to the best of the Operating Partnership’s and the Company’s knowledge, proposed for inclusion on the National Priorities List issued pursuant to CERCLA by the United States Environmental Protection Agency (the “EPA”) or, to the best of the Operating Partnership’s and the Company’s knowledge, proposed for inclusion on any similar list or inventory issued pursuant to any other Environmental Law or issued by any other governmental authority. Except as disclosed in the Prospectus, to the knowledge of the Company, there are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of Properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) that would, individually or in the aggregate, have a Material Adverse Effect.

(ff) Qualification as a REIT. The Company has been organized and has operated in conformity with the requirements for qualification and taxation as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”) for its taxable years ended April 30, 2006 through April 30, 2009, and the Company’s current and proposed method of operation will enable it to continue to meet the requirements for taxation as a REIT under the Code for its taxable year ending April 30, 2010 and in the future. The Subsidiaries of the Company that are partnerships have been and will continue to be treated as partnerships for federal income tax purposes and not as corporations, associations taxable as corporations or as publicly traded partnerships.

(gg) Intellectual Property. The Company and its Subsidiaries own and have full right, title and interest in and to, or has valid licenses to use, each material trade name, trademark, service ▇▇▇▇, patent, copyright, approval, trade secret and other similar rights (collectively “Intellectual Property”) under which the Company and its Subsidiaries conduct all or any material part of their business, and none of the Company and its Subsidiaries has created any lien or encumbrance on, or granted any right or license with respect to, any such Intellectual Property except where the failure to own or obtain a license or right to use any such Intellectual Property has not and will not have a Material Adverse Effect; there is no claim pending or, to the knowledge of the Company, threatened, against the Company or any of its Subsidiaries with respect to any Intellectual Property, and none of the Company and its Subsidiaries has received notice or otherwise become aware that any Intellectual Property that it uses or has used in the conduct of its business infringes upon or conflicts with the rights of any third party.

(hh) Title Insurance. Owner or leasehold title insurance in favor of the Company, the Operating Partnership and the Subsidiaries has been obtained with respect to each Property owned by any such entity, except where the failure to do so would not have a Material Adverse Effect, in an amount at least equal to amounts that are generally deemed in the Company’s industry to be commercially reasonable in the market where the Properties are located. The Company, the Operating Partnership and each of the Subsidiaries maintains insurance covering its Properties, operations, personnel and businesses as the Company deems adequate; such insurance insures against such losses and risks to an extent which is adequate in accordance with customary industry practice to protect the Company, the Operating Partnership and the Subsidiaries and their businesses; such insurance as the Company deems adequate and that insures against losses and risks to an extent which is adequate in accordance with customary industry practice is fully in force on the date hereof. The Company, Operating Partnership and each of the Subsidiaries do not have any reason to believe that they will not be able (i) to renew their existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct their business as now conducted.

(ii) ERISA Compliance. The Company and its Subsidiaries and any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its Subsidiaries or their ERISA Affiliates (as defined below) are in compliance in all material respects with ERISA and all other applicable state and federal laws. “ERISA Affiliate” means, with respect to the Company or a Subsidiary, any member of any group or organization described in Sections 414(b), (c), (m) or (o) of the Code of which the Company or such Subsidiary is a member. No “reportable event” (as defined in ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its Subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its Subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined in ERISA). Neither the Company, its Subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each “employee benefit plan” established or maintained by the Company, its Subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, that would cause the loss of such qualification.

(jj) Labor and Employment. The Company and its Subsidiaries have complied and will comply in all material respects with wage and hour determinations issued by the U.S. Department of Labor under the Service Contract Act of 1965 and the Fair Labor Standards Act in paying its employees’ salaries, fringe benefits and other compensation for the performance of work or other duties in connection with contracts

with the U.S. government, except where the failure to do so would not have a Material Adverse Effect, and have complied and will comply in all material respects with the requirements of the Americans with Disabilities Act of 1990, the Family and Medical Leave Act of 1993, the Civil Rights Act of 1964 (Title VII), the National Labor Relations Act, the Vietnam Era Veteran’s Readjustment Act, the Age Discrimination in Employment Act, as amended by the Older Workers’ Benefit Protection Act, and federal, state and local labor laws, each as amended except where the failure to comply with any such requirements has not, and will not, have a Material Adverse Effect.

(kk) ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. Except with respect to any non-timely filings of reports pursuant to Section 16(a) of the Exchange Act by certain of the Company’s officers and/or trustees as described in the Company’s most recently filed Definitive Proxy Statement under the caption “Section 16(a) Beneficial Ownership Reporting Compliance,” there is and has been no failure on the part of the Company to comply in all material respects with the provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated thereunder.

(ll) Brokers and Finders. Other than this Agreement, there are no contracts, agreements or understandings between the Company or any of its Subsidiaries and any person that would give rise to a valid claim against the Company or any of its Subsidiaries or the Underwriters for a brokerage commission, finder’s fee or other like payment with respect to the consummation of the transactions contemplated by this Agreement.

(mm) Money Laundering. The operations of the Company and its Subsidiaries are and have been conducted at all times in compliance with applicable financial record-keeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, applicable money laundering statutes and applicable rules and regulations thereunder (collectively, the “Money Laundering Laws”), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any or its Subsidiaries with respect to the Money Laundering Laws is pending or, to the Company’s knowledge, threatened.

(nn) Related Party Transactions. Except as set forth in the Prospectus (as amended or supplemented), there are no transactions with “affiliates” (as defined in Rule 405 of the Securities Act) or any officer, trustee or security holder of the Company (whether or not an affiliate) that are required by the Securities Act to be disclosed in the Prospectus that have not been disclosed as required. Additionally, no relationship, direct or indirect, exists between the Company or any of its Subsidiaries on the one hand, and the trustees, officers, shareholders, tenants, customers or suppliers of the Company or any Subsidiary on the other hand that is required by the Securities Act to be disclosed in the Prospectus that is not so disclosed.

(oo) Officer’s Certificates; Opinions. Any certificate signed by an officer of the Company and delivered to the Representatives or to counsel for the Underwriters shall be deemed to be a representation and warranty by the Company and/or the Operating Partnership, as applicable, to the Representatives as to the matters set forth therein.

If settlement for the Additional Shares occurs after the Closing Date, the Company will deliver to the Representatives on the Option Closing Date for the Additional Shares, and the obligation of the Underwriters to purchase the Additional Shares shall be conditioned upon receipt of, opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 7 hereof.

The Company further agrees (i) to furnish to the Representatives a copy of each proposed Free Writing Prospectus relating to the offering of the Shares to be prepared by or on behalf of, used by, referred to or filed by the Company and not to use, refer to or file any proposed Free Writing Prospectus relating to the offering of the Shares to which the Representatives object; and (ii) not to take any action that would result in the Representatives or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a Free Writing Prospectus prepared by or on behalf of the Representatives that the Representatives otherwise would not have been required to file thereunder.

(c) Registration Statement Amendments. After the date of this Agreement and during any period in which a Prospectus relating to the Shares is required to be delivered by the Underwriters under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act), (i) the Company will notify the Representatives as promptly as reasonably practicable of the time when any subsequent amendment to the Registration Statement, other than documents incorporated by reference, has been filed with the Commission and/or has become effective or any subsequent supplement to the Prospectus has been filed and of any comment letter from the Commission or any request by the Commission for any amendment or supplement to the Registration Statement or Prospectus or for additional information, (ii) the Company will prepare and file with the Commission, as promptly as reasonably practicable upon the Representatives’ request, any amendments or supplements to the Registration Statement or Prospectus that, in the Representatives’ reasonable opinion, may be necessary or advisable in connection with the distribution of the Shares by the Underwriters (provided, however, that the failure of the Representatives to make such request shall not relieve the Company of any obligation or liability hereunder, or affect the Underwriters’ right to rely on the representations and warranties made by the Company in this Agreement); (iii) the Company will not file any amendment or supplement to the Registration Statement or Prospectus, other than documents incorporated by reference, relating to the Shares or a security convertible into the Shares unless a copy thereof has been submitted to the Representatives within a reasonable period of time before the filing and the Representatives have not reasonably objected thereto (provided, however, that the failure of the Representatives to make such

If during such period any event occurs as a result of which the Registration Statement or the Prospectus, as then amended or 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 during such period it is necessary to amend or supplement the Registration Statement or Prospectus to comply with the Securities Act, the Company will promptly notify the Representatives to suspend the offering of Shares during such period, and the Company will as promptly as reasonably practicable amend or supplement the Registration Statement or Prospectus (at the expense of the Company) so as to correct such statement or omission or effect such compliance.

None of the following events shall have occurred and be continuing: (i) receipt by the Company or any of its Subsidiaries of any request for additional information from the Commission or any other federal or state governmental authority during the period of effectiveness of the Registration Statement, the response to which would require any post-effective amendments or supplements to the Registration Statement or the Prospectus; (ii) the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; (iv) the occurrence of any event that makes any material statement made in the Registration Statement or the Prospectus or any material document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in the Registration Statement, related Prospectus or such documents so that, in the case of the Registration Statement, it will not contain any materially untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and, that in the case of the Prospectus, it will not contain any materially untrue statement of a material fact or omit to state any 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.

(b) No Misstatement or Material Omission. The Representatives shall not have advised the Company that the Registration Statement or Prospectus, or any amendment or supplement thereto, contains an untrue statement of fact that in the Representatives’ reasonable opinion is material, or omits to state a fact that in the Representatives’ opinion is material and is required to be stated therein or is necessary to make the statements therein not misleading.

(c) Material Changes. Except as contemplated in the Prospectus, or disclosed in the Company’s reports filed with the Commission, there shall not have been any material adverse change, on a consolidated basis, in the authorized shares of beneficial interest of the Company or any Material Adverse Effect, or any development that could reasonably be expected to cause a Material Adverse Effect, or any downgrading in or withdrawal of the rating assigned to any of the Company’s or the Operating Partnership’s securities (other than asset backed securities) by any rating organization or a public announcement by any rating organization that it has under surveillance or review its rating of any of the Company’s or the Operating Partnership’s securities (other than asset backed securities), the effect of which, in the case of any such action by a rating organization described above, in the reasonable judgment of the Representatives (without relieving the Company or the Operating Partnership of any obligation or liability it may otherwise have), is so material as to make it impracticable or inadvisable to proceed with the offering of the Shares on the terms and in the manner contemplated in the Prospectus.

(d) No Termination Event. There shall not have occurred any event that would permit the Underwriters to terminate this Agreement pursuant to Section 11 hereof.

(e) Company Counsel Opinion. The Underwriters shall have received on the Closing Date and each Option Closing Date, if any, the opinion of Hunton & ▇▇▇▇▇▇▇▇ LLP, outside counsel for the Company and the Operating Partnership, with respect to certain corporate matters, tax matters and its negative assurance statement, dated the Closing Date and any Option Closing Date, each addressed to the Underwriters, in the form set forth in Exhibit A hereto. With respect to any matter covered by the laws of the State of North Dakota, counsel for the Company may rely on the opinion of counsel (which counsel shall be reasonably acceptable to the Representatives and its counsel) duly licensed to practice in such state in connection with the opinions required under this Section. In the alternative, the Company may request such North Dakota counsel to deliver its opinion directly to the Representatives.

(f) Underwriters’ Counsel Opinion. The Representatives shall have received from Bass, ▇▇▇▇▇ & ▇▇▇▇ PLC, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and any Option Closing Date, and addressed to the Underwriters, with respect to the issuance and sale of the Shares, the Registration Statement, the Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they may reasonably request for the purpose of enabling them to pass upon such matters.

(g) Comfort Letter. On the date of this Agreement and on the Closing Date (including any Option Closing Date, as the case may be) Deloitte & Touche LLP shall have furnished to the Representatives, at the request of the Company, letters, dated the respective dates of delivery thereof and addressed to the Underwriters, in form and substance reasonably satisfactory to the Representatives, containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement and the Prospectus (including the Incorporated Documents); provided, that the letter delivered on the Closing Date or any Option Closing Date, as the case may be, shall use a “cut-off” date no more than three (3) Business Days prior to such Closing Date or such Option Closing Date.

(h) Officers’ Certificate. The Company and the Operating Partnership shall have furnished to the Underwriters a certificate, signed by the President and the Chief Financial Officer of the Company (and appropriate officers of the Operating Partnership), dated the Closing Date and any Option Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Disclosure Package, the Prospectus, any supplements to the Prospectus and this Agreement and that:

(i) the representations and warranties of the Company and the Operating Partnership in this Agreement are true and correct on and as of the Closing Date or any Option Closing Date, as the case may be (except that to the extent that such representations and warranties speak as of another date, in which case such representations and warranties shall be true and correct as of such other date), and the Company and the Operating Partnership have complied with all the agreements and satisfied all the conditions on their part to be performed or satisfied at or prior to the Closing Date (or any Option Closing Date);

(ii) (A) as of the effective date of the registration statement, the Registration Statement and, as of the date of the Prospectus, the Closing Date and any Option Closing Date, the Prospectus, did not include any untrue statement of a material fact and did not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (with respect to the Prospectus, in light of the circumstances under which they were made), and (B) since the effective date of the Registration Statement no event has occurred which should have been set forth in a supplement or amendment to the Registration Statement or the Prospectus which has not been so set forth in such supplement or amendment;

(iii) the Registration Statement has become effective under the Securities Act and no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened; and

(iv) since the date of the most recent financial statements included in the Prospectus, there has been no Material Adverse Effect.

(i) Approval for Listing. The Shares to be sold by the Company as of the Closing Date or the Option Closing Date, as the case may be, shall have been duly approved for listing on the NASDAQ.

(j) Lock-Up Agreements. The “lock-up” agreements, each substantially in the form of Schedule IV hereto, between the Underwriters and certain officers and trustees of the Company listed on Schedule V relating to sales and certain other dispositions of Common Shares or certain other securities, delivered to the Representatives on or before the date hereof (unless otherwise noted in Schedule V hereto), shall be in full force and effect on the Closing Date.

(k) Other Materials. At the Closing Date and the Option Closing Date, counsel for the Underwriters shall have been furnished with such documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the Shares as herein contemplated and related proceedings, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained.

8. Indemnification and Contribution.

(a) Company and Operating Partnership Indemnification. The Company and the Operating Partnership, jointly and severally, agree to indemnify and hold harmless each Underwriter, the directors, officers, partners, employees and agents of any Underwriter and each person, if any, who (i) controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or (ii) is controlled by or is under common control with any Underwriter (“Underwriter Affiliate”) from and against any and all losses, claims, liabilities, expenses and damages (including, but not limited to, any and all reasonable investigative, legal and other expenses incurred in connection with, and any and all amounts paid in settlement (in accordance with Section 8(c) hereof) of, any action, suit or proceeding between any of the indemnified parties and any indemnifying parties or between any indemnified party and any third party, or otherwise, or any

claim asserted), as and when incurred, to which the Underwriters, or any such person, may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based, directly or indirectly, on (x) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Disclosure Package, any Issuer Free Writing Prospectus, any Permitted Free Writing Prospectus, any roadshow materials used in connection with the offer of the Shares, or the Prospectus, or any amendment or supplement to the foregoing, or in any application or other document executed by or on behalf of the Company or the Operating Partnership or based on written information furnished by or on behalf of the Company or the Operating Partnership filed in any jurisdiction in order to qualify the Shares under the securities laws thereof or filed with the Commission or (y) the omission or alleged omission to state in any such document a material fact required to be stated in it or necessary to make the statements in it not misleading; provided, however, that this indemnity agreement shall not apply to the extent that such loss, claim, liability, expense or damage arises from the sale of the Shares pursuant to this Agreement and is caused directly or indirectly by an untrue statement or omission made in reliance upon and in conformity with written information relating to any Underwriter and furnished to the Company in writing through the Representatives expressly for inclusion therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the third paragraph under the caption “Underwriting” and the information in the eighth through tenth paragraphs and the twelfth paragraph under the caption “Underwriting.” This indemnity agreement will be in addition to any liability that the Company or the Operating Partnership might otherwise have.

(b) Underwriters Indemnification. The Underwriters agree to indemnify and hold harmless the Company, its trustees, each officer of the Company that signed the Registration Statement, the Operating Partnership and each person, if any, who (i) controls the Company or the Operating Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act or (ii) is controlled by or is under common control with the Company or the Operating Partnership (a “Company Affiliate”) against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 8(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendments thereto), the Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information relating to any Underwriter and furnished to the Company in writing through the Representatives expressly for inclusion therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information set forth in subsection (a) above.

(c) Procedure. Any party that proposes to assert the right to be indemnified under this Section 8 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 8, notify in writing each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve the indemnifying party from (i) any liability that it might have to any indemnified party otherwise than under this Section 8 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this Section 8 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable

costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (iv) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. An indemnifying party will not, in any event, be liable for any settlement of any action or claim effected without its written consent. No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 8 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding.

(d) Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 8 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company, the Operating Partnership or the Underwriters, the Company and the Underwriters will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company or the Operating Partnership from persons other than the Underwriters, such as persons who control the Company or the Operating Partnership within the meaning of the Securities Act, officers of the Company who signed the Registration Statement and trustees of the Company, who also may be liable for contribution) to which the Company, the Operating Partnership and the Underwriters may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Operating Partnership, on the one hand, and the Underwriters, on the other. The relative benefits received by the Company and the Operating Partnership on the one hand and the Underwriters on the other hand shall be deemed to be in the same proportion as the total net proceeds from the sale of the Shares (before deducting expenses) received by the Company bear to the total compensation received by the Underwriters from the sale of Shares on behalf of the Company. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company and the Operating Partnership, on the one hand, and the Underwriters, on the other, with respect to the statements or omission that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to, among other things, 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 Operating Partnership, on the one hand, or the Underwriters, on the other, 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 Operating Partnership and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by

any other method of allocation that 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, liability, expense, or damage, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for the purpose of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim to the extent consistent with Section 8(c) hereof. Notwithstanding the foregoing provisions of this Section 8(d), the Underwriters shall not be required to contribute any amount in excess of the commissions received by them under this Agreement and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8(d), any person who controls a party to this Agreement within the meaning of the Securities Act, and any Underwriter Affiliate, will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 8(d), will notify any such party or parties from whom contribution may be sought, but the omission to so notify will not relieve that party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 8(d) except to the extent that the failure to so notify such other party materially prejudiced the substantive rights or defenses of the party from whom contribution is sought. Except for a settlement entered into pursuant to the last sentence of Section 8(c) hereof, no party will be liable for contribution with respect to any action or claim settled without its written consent if such consent is required pursuant to Section 8(c) hereof.

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Shares agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Shares set forth opposite their names in Schedule I hereto bears to the aggregate amount of Shares set forth opposite the names of all the nondefaulting Underwriters) the Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate number of Shares set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Shares, and if such nondefaulting Underwriters do not purchase all the Shares within 48 hours of default, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company or the Operating Partnership. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five (5) Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Survival of Certain Representations and Obligations. The indemnity and contribution agreements contained in Section 8, the provisions of Section 6 (Expenses) and all representations and warranties of the Company and the Operating Partnership herein or in certificates delivered pursuant hereto shall survive, regardless of (i) any investigation made by or on behalf of the Underwriters, any controlling persons, or the Company or the Operating Partnership (or any of their respective officers, trustees or controlling persons), (ii) delivery and acceptance of the Shares and payment therefor or (iii) any termination, default or cancellation of this Agreement.

11. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to the Closing

Date or, with respect to the purchase of Additional Shares, prior to any Option Closing Date (a) trading generally shall have been suspended or materially limited or minimum prices shall have been established on, or by, as the case may be, the New York Stock Exchange or the NASDAQ, (b) trading of any securities of the Company shall have been suspended or materially limited on any exchange or in any over-the-counter market, (c) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (d) any moratorium or material limitation on commercial banking activities shall have been declared by Federal or New York state authorities, (e) there shall have occurred any outbreak or escalation of hostilities, act of terrorism involving the United States or declaration by the United States of a national emergency or war, or (f) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (e) or (f), in the Representatives’ judgment, is material and adverse and makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Disclosure Package or the Prospectus (exclusive of any supplement thereto). Any such termination shall be without liability of any party to any other party except that the provisions of Section 6 (Expenses), Section 8 (Indemnification and Contribution), Section 10 (Survival of Certain Representations and Obligations), Section 16 (Applicable Law; Consent to Jurisdiction) and Section 17 (Waiver of Jury Trial) hereof shall remain in full force and effect notwithstanding such termination.

12. Notices. Except as otherwise provided herein, all notices or other communications required or permitted to be given by any party to any other party pursuant to the terms of this Agreement shall be in writing, unless otherwise specified in this Agreement, as follows:

Neither this Agreement nor any term hereof may be amended except pursuant to a written instrument executed by the Company and the Underwriters. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable as written by a court of competent jurisdiction, then such provision shall be given full force and effect to the fullest possible extent that it is valid, legal and enforceable, and the remainder of the terms and provisions herein shall be construed as if such invalid, illegal or unenforceable term or provision was not contained herein, but only to the extent that giving effect to such provision and the remainder of the terms and provisions hereof shall be in accordance with the intent of the parties as reflected in this Agreement.

16. Applicable Law; Consent to Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York without regard to the principles of conflicts of laws. Each party hereby irrevocably submits to the non-exclusive jurisdiction of the state and federal courts sitting in the City of New York, for the adjudication of any dispute hereunder or in connection with any transaction contemplated hereby, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding,

any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof (certified or registered mail, return receipt requested) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.

(b) Each of the Company and the Operating Partnership is capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) Each of the Company and the Operating Partnership has been advised that the Underwriters and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company or the Operating Partnership and that the Underwriters have no obligation to disclose such interests and transactions to the Company or the Operating Partnership by virtue of any fiduciary, advisory or agency relationship;

(d) Each of the Company and the Operating Partnership waives, to the fullest extent permitted by law, any claims it may have against the Underwriters, for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Company or the Operating Partnership in respect of such a fiduciary claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company or the Operating Partnership, including shareholders, partners, employees or creditors of the Company or the Operating Partnership; and

(e) Each of the parties hereto is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof.

The foregoing sentence shall not apply to (a) transfers of Common Shares or any security convertible into Common Shares as a bona fide gift, or (b) distributions of Common Shares or any security convertible into Common Shares to limited partners or stockholders of the undersigned; provided that (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), reporting a reduction in beneficial ownership of Common Shares, shall be required or shall be voluntarily made during the Restricted Period referred to in the foregoing sentence. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Common Shares, except in compliance with the foregoing restrictions.

The restrictions set forth in the foregoing paragraph is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to, or

Such prohibited hedging or other transactions would include without limitation any short sale (whether or not against the box) or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the undersigned’s Common Shares or with respect to any security that includes, relates to, or derives any significant part of its value from the undersigned’s Common Shares.

If: (1) during the last 17 days of the Restricted Period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the Restricted Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Restricted Period; then the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The undersigned shall not engage in any transaction that may be restricted by this agreement during the 34-day period beginning on the last day of the Restricted Period unless the undersigned requests and receives prior written confirmation from the Company or the Representatives that the restrictions imposed by this agreement have expired.

The undersigned further represents and agrees that the undersigned has not taken and will not take, directly or indirectly, any action which is designed to or which has constituted or which might reasonably be expected to cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares, or which has otherwise constituted or will constitute any prohibited bid for or purchase of the Shares or any related securities.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns. Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

Very truly yours,
