▇▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

AmeriVest Properties Inc., a Maryland corporation (the “Company”), proposes to sell to the several underwriters (the “Underwriters”) named in Schedule I hereto for whom you are acting as representative (the “Representative”) an aggregate of shares (the “Firm Shares”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”). The respective amounts of the Firm Shares to be so purchased by the several Underwriters are set forth opposite their names in Schedule I hereto. The Company also proposes to sell at the Underwriters’ option an aggregate of up to additional shares of the Company’s Common Stock (the “Option Shares”) as set forth below.

As the Representative, you have advised the Company (a) that you are authorized to enter into this underwriting agreement (this “Agreement”) on behalf of the several Underwriters, and (b) that the several Underwriters are willing, acting severally and not jointly, to purchase the numbers of Firm Shares set forth opposite their respective names in Schedule I, plus their pro rata portion of the Option Shares if you elect to exercise the over-allotment option in whole or in part for the accounts of the several Underwriters. The Firm Shares and the Option Shares (to the extent the aforementioned option is exercised) are herein collectively called the “Shares.”

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form SB-2 (File No. 333-105183), which contains a form of prospectus to be used in connection with the public offering and sale of the Shares. Such registration statement, as amended, including the financial statements, exhibits, notes and schedules thereto, in the form in which it was declared effective by the Commission under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), including any information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A or Rule 434 under the Securities Act, is called the “Registration Statement.” Any registration statement filed by the Company pursuant to Rule 462(b) under the Securities Act is called the “Rule 462(b) Registration Statement,” and from and after the date and time of filing of the Rule 462(b) Registration Statement, the term “Registration Statement” shall include the Rule 462(b) Registration Statement. Such prospectus, in the form first used by the Underwriters to confirm sales of the Shares, is called the “Prospectus.” Each preliminary prospectus provided to you for use with prospective investors and included in the Registration Statement prior to the time it becomes effective is herein referred to as a “Preliminary Prospectus.” All references in this Agreement to the Registration Statement, the Rule 462(b) Registration Statement, a Preliminary Prospectus or the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“▇▇▇▇▇”).

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

The Company represents and warrants to each of the Underwriters as follows:

(a) The Registration Statement and any Rule 462(b) Registration Statement have been filed with the Commission. The Company has complied with the conditions for the use of Form SB-2. The Registration Statement and any Rule 462(b) Registration Statement have been declared effective by the Commission under the Securities Act, and no post-effective amendment to the Registration Statement has been filed as of the date of this Agreement. The Company has complied with all requests of the Commission for additional or supplemental information. No stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the best of the Company’s knowledge, are contemplated or threatened by the Commission.

Each Preliminary Prospectus and the Prospectus when filed complied in all material respects with the Securities Act and, if filed by electronic transmission pursuant to ▇▇▇▇▇ (except as may be permitted by Regulation S-T under the Securities Act), was identical to the copy thereof delivered to the Underwriters for use in connection with the offer and sale of the Shares. Each of the Registration Statement (including any Rule 462(b) Registration

Statement) and any post-effective amendment thereto, at the time it became effective and at all subsequent times, complied and will comply in all material respects with the Securities Act and did not and will not contain any 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. Each Preliminary Prospectus, at the time of filing thereof, did not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus, as amended and supplemented, as of its date and at all subsequent times, did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in the three immediately preceding sentences do not apply to statements in or omissions from the Registration Statement, any Rule 462(b) Registration Statement, or any post-effective amendment thereto, any Preliminary Prospectus, or the Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing by the Representative expressly for use therein.

(b) The Company has delivered to the Representative a complete manually signed copy of the Registration Statement and of each consent and certificate of experts filed as a part thereof, and conformed copies of the Registration Statement (without exhibits) and Preliminary Prospectuses and the Prospectus, as amended or supplemented, in such quantities and at such places as the Representative has reasonably requested for each of the Underwriters.

(c) The Company has not distributed and will not distribute, prior to the later of the Option Closing Date (as defined below) and the completion of the Underwriters’ distribution of the Shares, any written offering material (including, without limitation, content on the Company’s Web site that may be deemed to be offering material) in connection with the offering and sale of the Shares other than a Preliminary Prospectus, the Prospectus or the Registration Statement.

(d) There are no contracts or other documents required to be described in the Prospectus or to be filed as exhibits to the Registration Statement which have not been described or filed as required. The contracts so described in the Prospectus to which the Company is a party have been duly authorized, executed and delivered by the Company, constitute valid and binding agreements of the Company, and are enforceable against and, to the best of the Company’s knowledge by, the Company in accordance with their respective terms. To the best of the Company’s knowledge, no other party is in material breach of or material default under any of such contracts.

(e) This Agreement has been duly authorized, executed and delivered by the Company, and constitutes a valid, legal, and binding obligation of the Company, enforceable in accordance with its terms, except as rights to indemnity hereunder may be limited by federal or state securities laws and except as such enforceability may be limited by bankruptcy, insolvency,

reorganization or similar laws affecting the rights of creditors generally, and subject to general principles of equity.

(f) The Shares to be purchased by the Underwriters from the Company have been duly authorized for issuance and sale pursuant to this Agreement and, when issued and delivered by the Company pursuant to this Agreement, will be validly issued, fully paid and nonassessable.

(g) There are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated by this Agreement, except for such rights as have been duly satisfied or waived.

(h) Except as otherwise disclosed in the Prospectus, subsequent to the respective dates as of which information is given in the Prospectus: (i) there has been no material adverse change, or any development that could reasonably be expected to result in a material adverse change, in the condition, financial or otherwise, or in the earnings, business, operations or prospects, whether or not arising from transactions in the ordinary course of business, of the Company and its subsidiaries, considered as one enterprise (any such change or development is called a “Material Adverse Change”); (ii) the Company and its subsidiaries, considered as one enterprise, have not incurred any material liability or obligation, indirect, direct or contingent, not in the ordinary course of business, nor entered into any material transaction or agreement not in the ordinary course of business; (iii) there has been no material casualty loss or condemnation or other material adverse event with respect to any of the real properties or interests in real properties owned by the Company and its subsidiaries (collectively, the “Properties”); and (iv) there has been no dividend or distribution of any kind declared, paid or made by the Company or, except for dividends or distributions paid to the Company or other subsidiaries, any of its subsidiaries on any class of capital stock or other equity interests or repurchase or redemption by the Company or any of its subsidiaries of any class of capital stock or other equity interests.

(i) Both KPMG LLP and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP, who have expressed their opinions with respect to the financial statements (which term as used in this Agreement includes the related notes and schedules thereto) filed with the Commission as a part of the Registration Statement and included in the Prospectus, were, at the time of such reports, independent public or certified public accountants as required by the Securities Act and the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”).

(j) The financial statements filed with the Commission as a part of the Registration Statement and included in the Prospectus present fairly and accurately (i) the consolidated financial position of the Company and its subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified and, (ii) the statement of revenue and certain expenses of Southwest Gas Office Building for the periods specified. Any supporting schedules included in the Registration Statement present fairly and

accurately the information required to be stated therein. Such financial statements and supporting schedules have been prepared in conformity with United States generally accepted accounting principles applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto, and all adjustments necessary for a fair presentation of results for such periods have been made. The pro forma consolidated financial statements of the Company and its subsidiaries and the related notes thereto and the statement of estimated taxable operating results and cash to be made available by operations based thereon included in the Prospectus and the Registration Statement present fairly and accurately the information contained therein, have been prepared in accordance with the Commission’s rules and guidelines with respect thereto and have been properly presented on the bases described therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein. No other financial statements or supporting schedules are required to be included in the Registration Statement. The financial data set forth in the Prospectus under the captions “Prospectus Summary — Summary Financial Data,” “Capitalization” and “Selected Financial Information” fairly and accurately present the information set forth therein on a basis consistent with that of the financial statements contained in the Registration Statement when read in conjunction with the textual information included in those sections.

(k) Each of the Company and its subsidiaries that is a corporation has been duly incorporated and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation and has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and, in the case of the Company, to enter into and perform its obligations under this Agreement, including corporate power and authority to authorize, issue and sell the Shares. Each subsidiary of the Company that is a limited liability company has been duly organized and is validly existing as a limited liability company in good standing under the laws of the jurisdiction of its organization and has limited liability company power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus. Each of the Company and its subsidiaries is duly qualified as a foreign corporation or limited liability company, as the case may be, to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Change. All of the issued and outstanding capital stock of each subsidiary of the Company that is a corporation has been duly authorized and validly issued, is fully paid and nonassessable and is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, claim, restriction or encumbrance, and all of the issued and outstanding membership interests of each subsidiary of the Company that is a limited liability company have been duly authorized and validly issued and are fully paid and are owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, claim, restriction or encumbrance. The Company does not own or control, directly or indirectly, any corporation, association or other entity other than the subsidiaries listed in Exhibit 21 to the Registration Statement.

(l) The authorized capital stock of the Company is as set forth in the Prospectus under the caption “Description of Securities.” The issued and outstanding Common Stock is as set forth in the Prospectus (other than for subsequent issuances, if any, pursuant to employee benefit plans described in the Prospectus, upon exercise of outstanding options or warrants described in the Prospectus or under the Company’s current dividend reinvestment plan (the “DRIP”)). The Common Stock (including the Shares) conforms in all material respects to the description thereof contained in the Prospectus. All of the issued and outstanding shares of Common Stock have been duly authorized and validly issued, are fully paid and nonassessable and have been issued in compliance with applicable federal and state securities laws. None of the outstanding shares of Common Stock was issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company. There are no authorized or outstanding options, warrants, preemptive rights, rights of first refusal or other rights to purchase, or equity or debt securities convertible into or exchangeable or exercisable for, any capital stock of the Company or any of its subsidiaries other than those described in the Prospectus. The description of the Company’s stock option, stock bonus and other stock plans or arrangements, and of the options or other rights granted thereunder, set forth in the Prospectus fairly and accurately presents the information required to be shown with respect to such plans, arrangements, options and rights.

(m) The Common Stock is registered pursuant to Section 12(b) of the Exchange Act, and is listed on the American Stock Exchange (the “AMEX”), and the Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting the Common Stock from the AMEX, nor has the Company received any notification that the Commission or the AMEX is contemplating terminating such registration or listing. Application has been made to list the Shares on the AMEX, and as of the Closing Date with respect thereto, the Shares shall have been approved for listing on the AMEX, subject to official notice of issuance.

(n) The Company and each of its subsidiaries have complied in all respects with all laws, regulations and orders applicable to them or their respective businesses, except as disclosed in the Prospectus or as would not result in a Material Adverse Change. Neither the Company nor any of its subsidiaries is in violation of its charter or by-laws or other organizational documents or in default (or, with the giving of notice or lapse of time or both, would be in default) (“Default”) under any indenture, mortgage, loan or credit agreement, note, contract, franchise, lease or other instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any of its subsidiaries is subject (each, an “Existing Instrument”), except such Defaults as would not, individually or in the aggregate, result in a Material Adverse Change. The Company’s execution, delivery and performance of this Agreement and consummation of the transactions contemplated hereby and by the Prospectus (i) have been duly authorized by all necessary corporate action and will not result in any violation of the provisions of the charter or by-laws or other organizational documents of the Company or any of its subsidiaries, (ii) will not conflict with or constitute a breach of, or a Default or Debt Repayment Triggering Event (as defined below) under, or result 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 require the consent of any other party to, any Existing Instrument, and (iii) will not result in any violation of any law, administrative regulation or administrative or court decree applicable to the Company or any of its subsidiaries. No consent, approval, authorization or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency, is required for the Company’s execution, delivery and performance of this Agreement and consummation of the transactions contemplated hereby and by the Prospectus, except such as have been obtained or made by the Company and are in full force and effect under the Securities Act and applicable state securities or blue sky laws and from the National Association of Securities Dealers, Inc. (the “NASD”).

As used herein, a “Debt Repayment Triggering Event” means any event or condition which gives, or with the giving of notice or lapse of time or both 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.

(o) There are no legal or governmental actions, suits or proceedings pending or, to the best of the Company’s knowledge, threatened (i) against or affecting the Company or any of its subsidiaries or (ii) which have as the subject thereof any officer or director of, or property owned or leased by, the Company or any of its subsidiaries, where in either such case (A) there is a reasonable possibility that such action, suit or proceeding might be determined adversely to the Company or such subsidiary and (B) any such action, suit or proceeding, if so determined adversely, would reasonably be expected to result in a Material Adverse Change or adversely affect the consummation of the transactions contemplated by this Agreement. No labor dispute with the employees of the Company, any of its subsidiaries or its advisor, exists or, to the best of the Company’s knowledge, is threatened or imminent, that could result in a Material Adverse Change.

(p) The Company and its subsidiaries own or possess sufficient trademarks, trade names, patent rights, copyrights, licenses, approvals, trade secrets and other similar rights (collectively, the “Intellectual Property Rights”) reasonably necessary to conduct their businesses as now conducted or as proposed to be conducted as described in the Prospectus; and the expected expiration of any of such Intellectual Property Rights would not result in a Material Adverse Change. Neither the Company nor any of its subsidiaries has received any notice of infringement or conflict with asserted Intellectual Property Rights of others, which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Change.

(q) The Company and each of its subsidiaries possesses such valid and current certificates, authorizations, licenses, registrations and permits (collectively, the “Permits”) issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct their respective businesses, and neither the Company nor any such subsidiary has received any notice of proceedings relating to the revocation or modification of, or noncompliance with, any

such Permits, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Change. The Company and each of the subsidiaries has fulfilled and performed all of its material obligations with respect to the Permits, and no event has occurred which allows, or after notice or lapse of time would allow, the revocation, termination, modification or other impairment of the rights of the Company or any of the subsidiaries under such Permit, except as would not result in a Material Adverse Change.

(r) The Company and each of its subsidiaries owns or leases under valid and binding leases all such properties as are necessary to its operations as now conducted or as proposed to be conducted as described in the Prospectus, except where the failure to so own or lease, individually or together with all such other failures, would not result in a Material Adverse Change. Except for the parcel located in Hempstead, Texas described in the Assignment of Lease dated February 4, 1999 between BPP-Lubbock, Inc. and AmeriVest Properties Texas, Inc., in which the Company holds a valid leasehold interest, the Company and its subsidiaries have good and marketable title in fee simple to all of the Properties, free and clear of all security interests, mortgages, pledges, liens, claims, restrictions or encumbrances of any kind, except such as (i) are described in the Prospectus or (ii) do not, individually or in the aggregate, materially affect the value of such Property and do not interfere with the use made and proposed to be made of such Property. All security interests, mortgages, pledges, liens, claims, restrictions and encumbrances of any kind on or affecting the Properties or the other assets of the Company and its subsidiaries that are required to be disclosed in the Prospectus are disclosed therein. There is no violation by the Company of any municipal, state or federal law, rule or regulation (including, but not limited to, those pertaining to environmental matters) concerning the Properties or any part thereof which would result in a Material Adverse Change. Each of the Properties complies with all applicable zoning laws, ordinances, regulations and deed restrictions or other covenants and, if and to the extent there is a failure to comply, such failure would not, individually or together with all such other failures, result in a Material Adverse Change or result in a forfeiture or reversion. Neither the Company nor any of its subsidiaries has received any notice from any governmental or regulatory authority or agency of any condemnation of or zoning change affecting the Properties or any part thereof, and the Company does not know of any such condemnation or zoning change which is threatened. No lessee of any portion of any of the Properties is in default under any of the leases governing such Properties and there is no event which, but for the passage of time or giving of notice or both, would constitute a default under any of such leases, except such defaults as would not, individually or in the aggregate, result in a Material Adverse Change.

(s) Except as set forth in the Prospectus, the mortgages and deeds of trust encumbering the Properties and any other assets described in the Prospectus are not convertible and none of the Company, any of its subsidiaries or any other person affiliated therewith holds a participating interest therein, and such mortgages and deeds of trust are not cross-defaulted or cross-collateralized to any property not owned directly or indirectly by the Company or any of its subsidiaries.

(t) The Company and its subsidiaries have filed all necessary federal, state, local and foreign income and franchise tax returns or have properly requested extensions thereof and have paid all taxes required to be paid by them and, if due and payable, any related or similar assessment, fine or penalty levied against any of them. The Company has made adequate charges, accruals and reserves in the applicable financial statements referred to in Section 1(j) above in respect of all federal, state, local and foreign income and franchise taxes for all periods as to which the tax liability of the Company or any of its subsidiaries has not been finally determined. The Company does not know of any actual or proposed additional material tax assessments. There are no transfer taxes or other similar fees or charges under federal law or the laws of any state, or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance by the Company or sale by the Company of the Shares.

(u) Commencing with the taxable year ended December 31, 1996 and through the date hereof, the Company has been and is organized in conformity with the requirements for qualification as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (collectively, the “Code”), and its actual and proposed method of operation has enabled and will enable it to meet the requirements for qualification and taxation as a REIT under the Code. No transaction or other event has occurred which would cause the Company to not be able to qualify as a REIT for its current taxable year or future taxable years.

(v) The Company has been advised of the rules and requirements under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Company is not, and after receipt of payment for the Shares will not be, an “investment company” within the meaning of the Investment Company Act and the Company presently intends to conduct its business in a manner so that it will not become subject to the Investment Company Act.

(w) The Company and each of its subsidiaries is insured by recognized and reputable institutions with policies in such amounts and with such deductibles and covering such risks as are generally deemed in the Company’s industry to be adequate and customary for their businesses, including, but not limited to, policies covering real and personal property owned or leased by the Company and its subsidiaries against theft, damage, destruction and acts of vandalism or terrorism and, with respect to the Properties, defects in title. The Company has no reason to believe that it or any of its subsidiaries will not be able either (i) to renew its 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 its business as now conducted or as proposed to be conducted as described in the Prospectus and at a cost that would not result in a Material Adverse Change. Neither the Company nor any of its subsidiaries has been denied any insurance coverage which it has sought or for which it has applied.

(x) Except for purchases or issuances of shares of Common Stock pursuant to the DRIP, the Company has not taken and will not take, directly or indirectly, any action designed to or that might be reasonably 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. None of such purchases and issuances pursuant to the DRIP was made by the administrator of the DRIP at the request of the Company with the purpose or intent of stabilizing or manipulating the price of any security of the Company to facilitate the sale or resale of the Shares. The Company acknowledges that the Underwriters may engage in passive market making transactions in the Shares on the AMEX in accordance with Regulation M under the Exchange Act.

(y) There are no business relationships or related-party transactions involving the Company or any of its subsidiaries or any other person required to be described in the Prospectus which have not been described as required. To the Company’s knowledge, there are no affiliations or associations between any member of the NASD and any of the Company’s officers, directors or 5% or greater security holders, except as set forth in the Registration Statement. Since July 30, 2002, the Company has not, in violation of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”), directly or indirectly, including through a subsidiary or related party, extended or maintained credit, arranged for the extension of credit, or renewed an extension of credit, in the form of a personal loan to or for any executive officer or director of the Company.

(z) Neither the Company nor any of its subsidiaries nor, to the best of the Company’s knowledge, any employee or agent of the Company or any subsidiary, has made any contribution or other payment to any official of, or candidate for, any federal, state or foreign office in violation of any law or of the character required to be disclosed in the Prospectus.

(aa) Except as otherwise disclosed in the Prospectus, or except as would not, individually or in the aggregate, result in a Material Adverse Change, (i) the Company and its subsidiaries have been and are in compliance with applicable Environmental Laws (as defined below), (ii) none of the Company, any of its subsidiaries or, to the best of the Company’s knowledge, any other owners of any of the Properties at any time or any other party, has at any time released (as such term is defined in CERCLA (as defined below)) or otherwise disposed of Hazardous Materials (as defined below) on, to, in, under or from the Properties or any other real properties previously owned, leased or operated by the Company or any of its subsidiaries, (iii) neither the Company nor any of its subsidiaries intends to use the Properties or any subsequently acquired properties, other than in compliance with applicable Environmental Laws, (iv) neither the Company nor any of its subsidiaries has received any notice of, or has any knowledge of any occurrence or circumstance which, with notice or passage of time or both, would give rise to a claim under or pursuant to any Environmental Law with respect to the Properties, any other real properties previously owned, leased or operated by the Company or any of its subsidiaries, or the assets described in the Prospectus or arising out of the conduct of the Company or its subsidiaries, (v) none of the Properties are included or, to the best of the Company’s knowledge, proposed for inclusion on the National Priorities List issued pursuant to CERCLA by the United States Environmental Protection Agency or, to the best of 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 (as defined below), (vi) none of the Company, any

of its subsidiaries or agents or, to the best of the Company’s knowledge, any other person or entity for whose conduct any of them is or may be held responsible, has generated, manufactured, refined, transported, treated, stored, handled, disposed, transferred, produced or processed any Hazardous Material at any of the Properties, except in compliance with all applicable Environmental Laws, and has not transported or arranged for the transport of any Hazardous Material from the Properties or any other real properties previously owned, leased or operated by the Company or any of its subsidiaries to another property, except in compliance with all applicable Environmental Laws, (vii) no lien has been imposed on the Properties by any Governmental Authority in connection with the presence on or off such Property of any Hazardous Material, and (viii) none of the Company, any of its subsidiaries or, to the best of the Company’s knowledge, any other person or entity for whose conduct any of them is or may be held responsible, has entered into or been subject to any consent decree, compliance order, or administrative order with respect to the Properties or any facilities or improvements or any operations or activities thereon.

As used herein, “Hazardous Material” shall include, without limitation, any flammable materials, explosives, radioactive materials, hazardous materials, hazardous substances, hazardous wastes, toxic substances or related materials, asbestos, petroleum, petroleum products and any hazardous material as defined by any federal, state or local environmental law, statute, ordinance, rule or regulation, including, without limitation, the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C. §§ 9601-9675 (“CERCLA”), the Hazardous Materials Transportation Act, as amended, 49 U.S.C. §§ 5101-5127, the Resource Conservation and Recovery Act, as amended, 42 U.S.C. §§ 6901-6992k, the Emergency Planning and Community Right-to-Know Act of 1986, 42 U.S.C. §§ 11001-11050, the Toxic Substances Control Act, 15 U.S.C. §§ 2601-2692, the Federal Insecticide, Fungicide and Rodenticide Act, 7 U.S.C. §§ 136-136y, the Clean Air Act, 42 U.S.C. §§ 7401-7642, the Clean Water Act (Federal Water Pollution Control Act), 33 U.S.C. §§ 1251-1387, the Safe Drinking Water Act, 42 U.S.C. §§ 300f-300j-26, and the Occupational Safety and Health Act, 29 U.S.C. §§ 651-678, and any analogous state laws, as any of the above may be amended from time to time and in the regulations promulgated pursuant to each of the foregoing (including environmental statutes and laws not specifically defined herein) (individually, an “Environmental Law” and collectively, the “Environmental Laws”) or by any federal, state or local governmental authority having or claiming jurisdiction over the properties and assets of the Company and its subsidiaries (a “Governmental Authority”).

(bb) In the ordinary course of its business, the Company periodically reviews the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, and periodically identifies and evaluates associated costs and liabilities (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). On the basis of such reviews and the amount of its established reserves, the Company has reasonably concluded that such associated costs and liabilities would not, individually or in the aggregate, result in a Material Adverse Change.

(cc) The Company 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 or its ERISA Affiliates (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Code of which the Company is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company or any of its ERISA Affiliates. No “employee benefit plan” established or maintained by the Company or any of its ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the Company nor any of its 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 or any of its 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, which would cause the loss of such qualification.

Any certificate signed by an officer of the Company and delivered to the Representative or to counsel for the Underwriters shall be deemed to be a representation and warranty by the Company to each Underwriter as to the matters set forth therein.

2. PURCHASE, SALE AND DELIVERY OF THE SHARES.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Company agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $ per share, the number of Firm Shares set forth opposite the name of each Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 9 hereof.

(b) Payment for the Firm Shares to be sold hereunder is to be made in New York Clearing House funds by wire transfer to the Company of immediately available funds against delivery of certificates therefor to the Representative for the several accounts of the Underwriters. Such delivery shall be made through the facilities of the Depository Trust Company, New York, New York at 10:00 a.m., New York time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as you and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.” As used herein, “business day” means a day on which the AMEX is open for trading and on which banks in New York are open for business and are not permitted by law or executive order to be closed.

(c) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the several Underwriters to purchase the Option Shares at the price per share as set forth in the first paragraph of this Section. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date or (ii) at any time thereafter within 30 days after the date of this Agreement, by you, as the Representative of the several Underwriters, to the Company setting forth the number of Option Shares as to which the several Underwriters are exercising the option, the names and denominations in which the Option Shares are to be registered and the time and date at which such certificates are to be delivered. The time and date at which certificates for Option Shares are to be delivered shall be determined by the Representative and may be the Closing Date, but otherwise shall not be earlier than three nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date, if subsequent to the Closing Date, being herein referred to as the “Option Closing Date”). The number of Option Shares to be purchased by each Underwriter shall be in the same proportion to the total number of Option Shares being purchased as the

number of Firm Shares being purchased by such Underwriter bears to the total number of Firm Shares, adjusted by you in such manner as to avoid fractional shares. The option with respect to the Option Shares granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters. You, as the Representative of the several Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company. To the extent, if any, that the option is exercised, payment for the Option Shares shall be made on the Closing Date or the Option Closing Date by wire transfer to the Company of immediately available funds and delivery of the Option Shares shall be made through the facilities of the Depository Trust Company in New York, New York.

3. OFFERING BY THE UNDERWRITERS.

It is understood that the several Underwriters are to make a public offering of the Firm Shares as soon as the Representative deems it advisable to do so. The Firm Shares are to be initially offered to the public at the initial public offering price set forth in the Prospectus. The Representative may from time to time thereafter change the public offering price and other selling terms. To the extent, if at all, that any Option Shares are purchased pursuant to Section 2 hereof, the Underwriters will offer them to the public on the foregoing terms.

It is further understood that you will act as the Representative for the Underwriters in the offering and sale of the Shares in accordance with a Master Agreement Among Underwriters entered into by you and the several other Underwriters.

4. COVENANTS OF THE COMPANY.

The Company covenants and agrees with the several Underwriters that:

(a) The Company will (i) use its reasonable best efforts to cause the Registration Statement or any Rule 462(b) Registration Statement to become effective or, if the procedure in Rule 430A under the Securities Act is followed, to prepare and timely file with the Commission under Rule 424(b) under the Securities Act a Prospectus in a form approved by the Representative containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430A under the Securities Act; (ii) not file any amendment to the Registration Statement or any Rule 462(b) Registration Statement or supplement to the Prospectus of which the Representative shall not previously have been advised and furnished with a copy or to which the Representative shall have reasonably objected in writing or which is not in compliance with the Securities Act; and (iii) file on a timely basis, and in compliance with the Exchange Act and § 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, all reports and any definitive proxy or information statements required to be filed by the Company with the Commission subsequent to the date of the Prospectus and prior to the termination of the offering of the Shares by the Underwriters.

(b) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(c) The Company will advise the Representative promptly (i) when the Registration Statement or any post-effective amendment thereto shall have become effective; (ii) of receipt of any comments from the Commission; (iii) of any request of the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information; and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus or of the institution of any proceedings for that purpose. The Company will use its best efforts to prevent the issuance of any such stop order preventing or suspending the use of the Prospectus and to obtain as soon as possible the lifting thereof, if issued.

(d) The Company will cooperate with the Representative in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representative may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representative may reasonably request for distribution of the Shares.

(e) The Company will deliver to, or upon the order of, the Representative, from time to time, as many copies of any Preliminary Prospectus as the Representative may reasonably request. The Company will deliver to, or upon the order of, the Representative during the period when delivery of a Prospectus is required under the Securities Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Representative may reasonably request. The Company will deliver to the Representative at or before the Closing Date, four signed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Representative such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested) and of all amendments thereto, as the Representative may reasonably request.

(f) The Company will comply with the Securities Act and the Exchange Act, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus. If during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with any law, the Company promptly will prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the law.

(g) The Company will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after the effective date of the Registration Statement, an earning statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earning statement shall satisfy the requirements of Section 11(a) of the Securities Act and Rule 158 under the Securities Act and will advise you in writing when such statement has been so made available.

(h) Prior to the Closing Date, the Company will furnish to the Underwriters, as soon as they have been prepared by or are available to the Company, a copy of any unaudited interim financial statements of the Company for any period subsequent to the period covered by the most recent financial statements appearing in the Registration Statement and the Prospectus.

(i) No offering, sale, short sale or other disposition of any shares of Common Stock of the Company or other securities convertible into or exchangeable or exercisable for shares of Common Stock or derivatives of Common Stock (or agreement for such) will be made for a period of 90 days after the date of this Agreement, directly or indirectly, by the Company otherwise than hereunder or with your prior written consent; provided, however, that the Company may (i) issue shares of Common Stock upon the exercise of warrants outstanding on the date hereof and described in the Prospectus, (ii) grant options to purchase shares of Common Stock and issue shares of Common Stock upon the exercise of options, in both cases, pursuant to any stock option plan or arrangement described in the Prospectus, (iii) issue shares of Common Stock under the DRIP, (iv) issue shares of Common Stock (or securities convertible into Common Stock) in payment of all or a portion of the purchase price for properties acquired from sellers who are not affiliates of the Company (provided that in each of (i), (ii) and (iv) each recipient of such shares of Common Stock, or securities convertible into Common Stock, enters into a lock-up agreement with terms substantially equivalent to the lock-up agreements delivered to the Representative pursuant to Section 4(k)) and (v) file amendments and/or supplements to the Company’s previously filed registration statement relating to the Company’s July 2000 offering of 300,000 units consisting of shares of Common Stock and warrants for the purpose of updating any prospectus forming a part of such registration statement.

(j) The Company will use its best efforts to list, subject to notice of issuance, the Shares on the AMEX.

(k) The Company has caused each officer and director and specific shareholders of the Company to furnish to you, on or prior to the date of this agreement, a letter or letters, in form and substance satisfactory to the Underwriters, pursuant to which each such person shall agree not to offer, sell, sell short or otherwise dispose of any shares of Common Stock of the Company or other capital stock of the Company, or any other securities convertible, exchangeable or exercisable for Common Stock or derivative of Common Stock owned by such person or request the registration for the offer or sale of any of the foregoing (or as to which such person has the right to direct the disposition of) for a period of 45 days after the date of this

Agreement, directly or indirectly, except with the prior written consent of RBC ▇▇▇▇ ▇▇▇▇▇▇▇▇ Inc. (“Lockup Agreements”).

(l) The Company shall apply the net proceeds of its sale of the Shares as described under the heading “Use of Proceeds” in the Prospectus and shall report with the Commission with respect to the sale of the Shares and the application of the proceeds therefrom as may be required in accordance with Rule 463 under the Securities Act.

(m) The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the Company or any of the Subsidiaries to register as an investment company under the 1940 Act.

(n) The Company will maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Company, a registrar for the Common Stock.

5. COSTS AND EXPENSES.

The Company will pay all costs, expenses and fees incident to the performance of the obligations of the Company under this Agreement, including, without limiting the generality of the foregoing, the following: accounting fees of the Company; the fees and disbursements of counsel for the Company; the cost of printing and delivering to, or as requested by, the Underwriters copies of the Registration Statement, Preliminary Prospectuses, the Prospectus, the Underwriters’ selling memorandum and the Underwriters’ invitation letter, if any, the AMEX listing application, the blue sky survey and any supplements or amendments thereto; the filing fees of the Commission; the filing fees and expenses (including reasonable legal fees and disbursements of counsel for the Underwriters) incident to securing any required review by the NASD of the terms of the sale of the Shares; the listing fee of the AMEX; and the expenses, including the fees and disbursements of counsel for the Underwriters incurred in connection with the qualification of the Shares under state securities or blue sky laws.

The Company shall not, however, be required to pay for any of the Underwriters expenses (other than those related to qualification under NASD regulation and state securities or blue sky laws) except that, if this Agreement shall not be consummated because the conditions in Section 6 hereof are not satisfied, or because this Agreement is terminated by the Representative pursuant to Section 11(a) and Section 11(b) hereof, or by reason of any failure, refusal or inability on the part of the Company to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof on its part to be performed, then the Company shall reimburse the several Underwriters for reasonable out-of-pocket expenses, including all fees and disbursements of counsel, reasonably incurred in connection with investigating, marketing and proposing to market the Shares or in contemplation of performing their obligations hereunder; but the Company shall not in any event be liable to any of the several Underwriters for damages on account of loss of anticipated profits from the sale by them of the Shares.

8. INDEMNIFICATION.

(a) The Company agrees:

(i) to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading any act or failure to act, or (iii) any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Shares or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided, however, that the Company shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct); provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus, or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representative specifically for use in the preparation thereof; provided, further, that with respect to any Preliminary Prospectus, the foregoing indemnity agreement shall not inure to the benefit of any Underwriter from whom the person asserting the loss, claim, damage or liability or expense purchased Shares, or any person controlling such Underwriter, if copies of the Prospectus were timely delivered to the Underwriter pursuant to Section 4(e) and a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage, liability or expense.

(ii) to reimburse each Underwriter and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto.

(b) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement or any Rule 462(b) Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, the Prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representative specifically for use in the preparation thereof.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a) or (b) shall be available to any party who shall fail to give notice as provided in this Subsection if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party otherwise than on account of the provisions of Section 8. In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with

counsel reasonably satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the reasonable fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action.

It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 8(a) and by the Company in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

(d) If the indemnification provided for in this Section is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds

from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Subsection 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 Subsection. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Subsection shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Subsection, (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discount applicable to the Shares purchased by such Underwriter and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Subsection to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) In any proceeding relating to the Registration Statement, any Preliminary Prospectus, the Prospectus or any supplement or amendment thereto, each party against whom contribution may be sought under this Section hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon him or it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join him or it as an additional defendant in any such proceeding in which such other contributing party is a party.

(f) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Company, its directors or officers or any persons controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section.

9. DEFAULT BY UNDERWRITERS.

If on the Closing Date or the Option Closing Date, if any, any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company, you, as the Representative of the Underwriters, shall use your reasonable efforts to procure within 48 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company such amounts as may be agreed upon and upon the terms set forth herein, the Firm Shares or Option Shares, as the case may be, which the defaulting Underwriter or Underwriters failed to purchase. If during such 48 hours you, as such Representative, shall not have procured such other Underwriters, or any others, to purchase the Firm Shares or Option Shares, as the case may be, agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of shares with respect to which such default shall occur does not exceed 10% of the Firm Shares or Option Shares, as the case may be, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Firm Shares or Option Shares, as the case may be, which they are obligated to purchase hereunder, to purchase the Firm Shares or Option Shares, as the case may be, which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of shares of Firm Shares or Option Shares, as the case may be, with respect to which such default shall occur exceeds 10% of the Firm Shares or Option Shares, as the case may be, covered hereby, the Company or you as the Representative of the Underwriters will have the right, by written notice given within the next 48-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company except to the extent provided in Section 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section, the Closing Date or Option Closing Date, if any, may be postponed for such period, not exceeding seven days, as you, as Representative, may determine in order that the required changes in the Registration Statement or in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

(a) at any time prior to the Closing Date if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement and the Prospectus, any Material Adverse Change or any development involving a prospective change, which has had or is reasonably likely to result in a Material Adverse Change, (ii) any outbreak or escalation of hostilities or declaration of war or national emergency or other national or international calamity or crisis or change in economic or political conditions if the effect of such outbreak, escalation, declaration, emergency, calamity, crisis or change on the financial markets of the United States would, in your reasonable judgment, make it impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares, or (iii) suspension of trading in securities generally on the New York Stock Exchange or the AMEX or limitation on prices (other than limitations on hours or numbers of days of trading) for securities on either such exchange, (iv) the enactment, publication, decree or other promulgation of any statute, regulation, rule or order of any court or other governmental authority which in your reasonable opinion materially and adversely affects or may materially and adversely affect the business or operations of the Company, (v) declaration of a banking moratorium by United States, Colorado, Maryland or New York State authorities; (vi) the suspension of trading of the Common Stock by the AMEX, the Commission, or any other governmental authority or, (vii) the taking of any action by any governmental body or agency in respect of its monetary or fiscal affairs which in your reasonable opinion has a material adverse effect on the securities markets in the United States; or

(b) as provided in Section 6 of this Agreement; or

12. SUCCESSORS.

This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
