PART II

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

        Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we have conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934 (the "Exchange Act"). Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2004 to ensure that information required to be disclosed in reports that are filed or submitted under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

Management's Report on Internal Control Over Financial Reporting

        Our management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. Our internal control over financial reporting includes those policies and procedures that:

•

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;



•

provide reasonable assurance that transactions are recorded as necessary to permit preparation of our financial statements in accordance with generally accepted accounting principles in the United States, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors, and



•

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

        In assessing the effectiveness of our system of internal control over financial reporting, our management used the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organization of the Treadway Commission ("COSO"). Based on our assessment and utilizing the criteria set forth by COSO, our management believes that the internal control of AmeriVest and its subsidiaries over financial reporting was effective as of December 31, 2004. Our assessment of the effectiveness of our internal control over financial reporting has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which is included below.

Inherent Limitations on Effectiveness of Controls

        Our system of internal control over financial reporting was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States.

        All internal control systems, no matter how well designed and operated, can provide only reasonable assurance with respect to financial statement preparation and presentation. Our management does not expect that our disclosure controls and procedures will prevent all error and fraud. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues within the company have been detected, even with respect to those systems of internal control that are determined to be effective. These inherent limitations include the realities that

1

---

judgments in decision-making can be faulty, and that breakdown can occur because of simple error or mistake. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of these inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Audit Committee Oversight

        The Audit Committee of the Board of Directors, which is comprised solely of independent directors, has oversight responsibility for our financial reporting process and the audits of our consolidated financial statements and internal control over financial reporting. The Audit Committee meets regularly with management and with our independent registered public accounting firm to review matters related to the quality and integrity of our financial reporting, internal control over financial reporting (including compliance matters related to our Code of Ethics), and the nature, extent, and results of external audits. Our auditors have full and free access and report directly to the Audit Committee. The Audit Committee recommended, and the Board of Directors approved, that the audited consolidated financial statements be included in the Annual Report on Form 10-K, and as subsequently approved in this Form 10-K/A.

Changes in Internal Control Over Financial Reporting

        There have not been any significant changes in AmeriVest's internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act during or since AmeriVest's fiscal quarter ended December 31, 2004 that have materially affected, or are reasonably likely to materially affect, AmeriVest's internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders
AmeriVest Properties Inc.:

        We have audited management's assessment, included in the accompanying Management's Report on Internal Control Over Financial Reporting appearing under Item 9A, that AmeriVest Properties Inc. maintained effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). AmeriVest Properties Inc.'s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of AmeriVest Properties Inc.'s internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal

2

---

control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, management's assessment that AmeriVest Properties Inc. maintained effective internal control over financial reporting as of December 31, 2004, is fairly stated, in all material respects, based on criteria established in Internal Control—Integrated Framework issued by the COSO Commission. Also, in our opinion, AmeriVest Properties Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control—Integrated Framework issued by the COSO Commission.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of AmeriVest Properties Inc. and subsidiaries as of December 31, 2004 and 2003, and the related consolidated statements of operations, shareholders' equity and cash flows for each of the years in the three-year period ended December 31, 2004, and our report dated March 16, 2005 expressed an unqualified opinion on those consolidated financial statements.

ITEM 11. EXECUTIVE COMPENSATION

Compensation of Executive Officers

        The following table sets forth in summary form the compensation we paid to the executive officers listed below for the year ended December 31, 2004, who are referred to in this section as the named executive officers. The four primary and on-going components of our executive compensation program are: salary, bonus, annual incentives, and long term incentives.

        The annual incentive component of our executive total compensation program for our Chief Executive Officer and Chief Operating Officer, established in May 2003, is in the form of an annual performance bonus. Specifically, we granted an annual performance bonus to each of Messrs. Atkins and Knight of up to $117,000 each, based on our total return performance over the year relative to other office real estate investment trusts ("REITs"), as determined by the National Association of Real

7

Estate Investment Trusts ("NAREIT"). At our discretion, bonuses over a certain size may be paid 50% in cash and 50% in restricted stock. In 2004, each of Messrs. Atkins and Knight earned no bonuses under the program. These bonuses are disclosed in the "Summary Compensation" table below.

        The long-term incentive component of our executive total compensation program for our Chief Executive Officer and Chief Operating Officer, established in May 2003, is in two forms, restricted stock grants and a three-year performance award. At that time, we made a restricted stock grant to each of Messrs. Atkins and Knight, each in the amount of 58,000 shares, to be awarded to each of them ratably over five years commencing January 2004. Each participant also will receive a cash payment equal to the amount of the dividend on the unvested shares. These restricted stock grants are disclosed in the "Summary Compensation" table below. In addition, we introduced a three-year performance award for Messrs. Atkins and Knight of up to $351,000 each, based on our total return performance over the three years ending December 31, 2005 relative to other office REITs, as determined by NAREIT. At our discretion, bonuses over a certain size may be paid 50% in cash and 50% in restricted stock. These long-term incentives are designed to focus the leadership team on driving both growth and continuous operational improvements that are critical to the future sustained success of the business, and are disclosed under "Long Term Incentive Plan Awards" below.

        Our other named executive officers are eligible for bonuses, payable in cash or stock, based on several factors, including individual and company goals and performance during the past year.

Employment, Termination of Employment and Change-in-Control Arrangements

Severance Agreement

        In December 2003, we entered into a Severance Agreement and Release with Mr. Scott Ikenberry, our former Chief Financial Officer. Under the terms of the agreement, Mr. Ikenberry received severance payments for twelve months commencing in January 2004, payable monthly, based on his monthly salary at the time he ceased being our Chief Financial Officer. During this severance period, Mr. Ikenberry also received, among other things, certain insurance coverage and other benefits, and an office and executive suite services at no charge for a one-year period which ended in December 2004.

        In April 2005, we entered into a Severance Agreement and Release with Mr. William T. Atkins, who had previously announced that he was resigning as the Company's Chief Executive Officer

9

---

effective April 30, 2005. Under the terms of the Severance and Release Agreement, Mr. Atkins' regular compensation will continue for a period of five (5) months, commencing May 1, 2005. In addition, the unvested portion of those restricted shares of common stock due to Mr. Atkins under the Company's Long-Term Incentive Plan (other than those shares that relate to the current or future performance of the Company) shall vest automatically on April 30, 2005, a total of 34,800 shares. Mr. Atkins will also be entitled to continued use of his existing or a similar office designated by the Company at the Sheridan center property in Denver, Colorado, at no charge to Mr. Atkins, for a period of one year, commencing May 1, 2005. The Severance and Release Agreement also contains customary indemnification provisions, releases, covenants, confidentiality, and non-solicitation provisions.

Change of Control Agreements

        On December 7, 2004, we entered into change of control agreements with Messrs. Atkins, Greenman and Knight and Ms. Hale. Mr. Atkins' agreement will terminate automatically when he ceases to be an officer of AmeriVest, effective April 30, 2005.

        Each agreement provides that upon a change of control, any and all common shares, options, or other forms of securities issued by us and beneficially owned by the executive (whether granted before or after the date of the change of control agreement) that are unvested, restricted, or subject to any similar restriction that would otherwise require continued ownership by the executive beyond the change of control date in order to be vested in the hands of the executive, shall vest automatically.

        In addition, if during the protection period following a change of control date, the executive's employment is terminated by us other than for cause or disability or other than as a result of the executive's death or if the executive terminates his employment for good reason, the Company (which means us or, if appropriate, our successor) shall pay to the executive in a lump sum in cash, within 10 days after the date of termination, the aggregate of the following amounts: accrued but unpaid base salary and vacation pay; a severance amount that other than with respect to Mr. Atkins, is equal to a multiple of the executive's annual and long-term compensation; and the value of any options or SARs held by such executive. For Mr. Knight, Mr. Greenman, and Ms. Hale, the multiples are 2.5, 2.0, and 1.5, respectively. For Mr. Atkins, the severance amount will be the sum of an amount not to exceed $700,000 due and payable if the Company exercises its termination right, such amount to be determined by the Board in its sole discretion before the change of control date, and an amount equal to 2.5 times the amount specified by the Company as long-term incentive compensation for Mr. Atkins for the year before the change of control occurs. The severance benefit shall be reduced as described below if the accountants determine (A) that the executive would, by reason of section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), be required to pay an excise tax on any part of the severance benefit or any part of any other payment or benefit to which executive is entitled under any plan, practice, policy, or program, and (B) the amount of the severance benefit that executive would retain on an after-tax basis, present value basis would be increased as a result of such reduction by an amount of at least $5,000. If the severance benefit is required to be reduced, it shall be reduced only to the extent required, in the opinion of the accountants, to prevent the imposition upon the executive of the tax imposed under section 4999 of the Code. The Company shall determine which elements of the severance benefit shall be reduced to conform to this requirement. Any determination made by the accountants shall be conclusive and binding on the executive.

        Similarly, at any time during the six month period following a change in control date, the executive shall have the right to terminate the executive's employment with the Company at the executive's sole discretion. In the event the executive exercises the executive termination right, the Company shall pay the executive in a lump sum in cash within 10 days after the date of termination the aggregate of the following amounts: accrued but unpaid base salary and vacation pay; a severance amount that is in most cases, is equal to a multiple of the executive's annual compensation; and the value of any options or SARs held by such Executive. For Mr. Knight, Mr. Greenman, and Ms. Hale, the multiple is 1.0.

10

For Mr. Atkins, the severance amount will be determined as described in the paragraph above, except that the multiple for the long-term incentive compensation portion of the severance amount will also be 1.0.

Equity Compensation Plan Information

        The following table summarizes our equity compensation plan information as of December 31, 2004. Information is included for both equity compensation plans approved by our stockholders and equity compensation plans not approved by our stockholders.

Plan Category			Shares of Common Stock to be Issued Upon Exercises of Outstanding Options, Warrants and Rights		Weighted-Average of Exercise Price of Outstanding Options, Warrants and Rights			Shares of Common Stock Available for Future Issuance Under Equity Compensation Plans (excluding securities reflected in the first column)
Equity Compensation Plans Approved by Stockholders			127,000		$	6.20		369,818
Equity Compensation Plans not Approved by Stockholders			0			n/a		0
	Totals		127,000		$	6.20		369,818

1995 and 1998 Stock Option Plans

        Pursuant to our 1995 and 1998 Stock Option Plans (collectively, the 95-98 Option Plans), we may grant options to purchase an aggregate of 330,000 shares of the Company's common stock to key employees, directors, and other persons who have or are contributing to the success of the Company. The options granted pursuant to the 95-98 Option Plans may be incentive options qualifying for beneficial tax treatment for the recipient, non-qualified options or non-qualified, non-discretionary options. Directors who are not employees of the Company (outside directors) automatically receive options to purchase 12,000 shares pursuant to the 95-98 Option Plans at the time of their election. None of these options are exercisable at the time of grant. One-third of these options become exercisable on December 30 of each of the first three years immediately following the date of grant. The exercise price for options granted to outside directors is the fair market value of the common stock on the date of grant, and all options granted to outside directors expire five years from the date of grant. On the date that all of an outside director's options become exercisable, options to purchase an additional 12,000 shares, none of which are exercisable at that time, shall be granted to that outside director.

        At December 31, 2004, options to purchase an aggregate of 127,000 shares of common stock were outstanding under the option plans. At December 31, 2004, no shares of common stock were available under the option plans.

        All options granted under the 1998 Stock Option Plan will become fully exercisable upon the occurrence of a change in control of AmeriVest upon certain mergers or other reorganizations or asset sales.

        Options granted under either the 1995 Stock Option Plan or the 1998 Stock Option Plan generally are not transferable during the option holder's lifetime.

2003 Long-Term Incentive Plan

        Our stockholders approved the AmeriVest Properties Inc. 2003 Long-Term Incentive Plan at our 2003 annual meeting. Pursuant to the 2003 Long-Term Incentive Plan, we may grant options, stock appreciation rights, bonus stock, stock units, performance shares, performance units, restricted stock

11

---

and restricted stock units equivalent to 500,000 shares of common stock (subject to individual limits). The options granted pursuant to the 2003 Long-Term Incentive Plan may be incentive stock options that qualify for beneficial tax treatment to the recipient or non-qualified stock options. It is expected that options and stock appreciation rights will satisfy the requirements for "performance-based compensation" as that term is used in section 162(m) of the Code.

        At December 31, 2004, 369,818 shares of common stock were available under the 2003 Long-Term Incentive Plan.

Compensation Committee Interlocks and Insider Participation

        The Compensation Committee currently consists of Mr. Holman (Chairman) and Messrs. Gelles and Tepper. The Compensation Committee is responsible for making recommendations to the Board of Directors regarding executive compensation matters. The Board of Directors has determined that all members of the Compensation Committee are "independent" within the meaning of the American Stock Exchange's listing standards, without reliance on exceptional or limited circumstances, and should continue to serve on the Compensation Committee until the Company's 2005 annual meeting of shareholders.
