The offering must be registered in every state in which we offer or sell shares.  Generally, such registrations are for a period of one year.  Thus, we may have to stop selling shares in any state in which our registration is not renewed or otherwise extended annually.

Pursuant to our charter, each of our directors is elected by our stockholders to serve until the next annual meeting of our stockholders and until their successors are duly elected and qualify. See “Provisions of Maryland Law and of Our Charter and Bylaws.” The next annual meeting of our stockholders will be held in 2011. Subject to rights pursuant to any employment agreements, officers serve at the pleasure of our board of directors.

We estimate that our executive officers will spend between 1/3 and 1/2 of their working time on our matters as opposed to those of other entities managed through Hartman Advisors, HIR Management or their affiliates.

The following is a biographical summary of the experience of our directors and executive officers.

Allen R. Hartman, age 59, is our CEO and Chairman of our Board of Directors as well as President of our advisor, Hartman Advisors, and our property manager, HIR Management. In 1984, Mr. Hartman formed Hartman Management and began sponsoring private real estate investment programs. Over the next 24 years, Mr. Hartman built Hartman Management into one of the leading commercial property management firms in the state of Texas and sponsored 20 privately offered programs and one publicly offered program that invested in commercial real estate in Houston, San Antonio and Dallas, Texas. In 1998, Mr. Hartman merged the Hartman real estate programs and formed Hartman Commercial Properties REIT (HCP REIT), now known as Whitestone REIT (see the discussion on page 139 below). He served as CEO and Chairman of the Board of HCP REIT until October, 2006. In April, 2008, Mr. Hartman merged 4 of the 5 Hartman programs to form Hartman Income REIT (HIREIT) and contributed the assets and ongoing business operations of Hartman Management into Hartman Income REIT Management, a wholly owned subsidiary of HIREIT. Currently Mr. Hartman oversees a staff of 55 employees who manage 29 commercial properties encompassing over 3.4 million square feet. In addition to his day-to-day management responsibilities, Mr. Hartman serves as the principal officer of each Hartman sponsored investment program. Mr. Hartman attended the University of Colorado and studied Business Administration.

Louis T. Fox, III, age 50, is our Chief Financial Officer. Mr. Fox also serves as Chief Financial Officer for our advisor and our property manager. He has responsibility for financial reporting, accounting, treasury and investor relations. Prior to joining Hartman Management (now, HIR Management) in March, 2007, Mr. Fox served as Chief Financial Officer of Legacy Brands, a restaurant group from April, 2006 until January, 2007. Prior to that, Mr. Fox served as Chief Financial Officer of Unidynamics, Inc., a specialized EPC manufacturer of unique handling system solutions for the marine and energy industries from January, 2004 until April, 2006. He also served as Treasurer and CFO of Goodman Manufacturing, a major manufacturer of residential and commercial HVAC products for 9 years prior to that. In addition to his years of experience in the manufacturing industry, he has served in senior financial positions in the construction and debt collection service concerns. Fox is a former practicing certified public accountant. He received a Bachelor of Arts degree in accounting from the University of Texas at San Antonio. He started his career as a tax accountant with Arthur Andersen & Co.

James H. Stokes Jr., age 54, is our General Counsel. Mr. Stokes also serves as General Counsel for both our advisor and property manager. In this capacity, Stokes manages our advisor’s in-house legal department and is responsible for all legal matters affecting the Hartman companies. Before joining Hartman Management, (now HIR Management) in September, 2006, Stokes spent over 20 years in his own private law practice, primarily in real estate, corporate law, bankruptcy and civil litigation. He also served as a branch manager for First Colony Commonwealth Title Company and American National Title. Stokes graduated from the University of Texas with a B.A. degree from the Plan II honors program in 1978 and continued his education at the University of Texas School of Law where he received his J.D in 1981.

After obtaining his MBA from Baylor University, Mr. Tompkins began his career with Arthur Young & Co., working as a certified public accountant there for three years before joining Arthur Andersen, L.L.P., where he was elected to the partnership in 1981 and served until 1988. While at Andersen he was in charge of the Merger and Acquisition Program for the Houston office as well as head of the Natural Gas Industry Group. From 1988 until October 1996, Mr. Tompkins served as Chief Financial Officer, Senior Vice President and Chief Information, Administrative & Accounting Officer of a large publicly traded energy company. Corporate functions reporting to Mr. Tompkins included financial planning, risk management, tax, accounting, information systems, administration and internal audit. Mr. Tompkins served as Chairman & CEO of Automotive Realty Trust Company of America from its inception in 1997 until its sale to a publicly traded REIT in January 1999. Automotive Realty was formed to engage in the business of consolidating real estate properties owned by automobile dealerships into a REIT. From March to September of 1999, Mr. Tompkins served as interim Executive Vice President and CFO of Crescent Real Estate Equities as the Company restructured.

Committees of the Board of Directors

Our entire board of directors considers all major decisions concerning our business, including any property acquisitions. However, we have established an audit committee, a compensation committee and a nominating committee so that certain functions can be addressed in more depth than may be possible at a full board meeting. Independent directors comprise all of the members of the audit committee, compensation committee and nominating committee.

Audit Committee

The audit committee meets on a regular basis at least four times a year. Our audit committee is comprised of our two independent directors, Jack Tompkins and Richard Ruskey. Our board of directors has adopted our Audit Committee Charter and it is posted on Hartman’s web site at www.hi-reit.com.  The audit committee’s primary functions are to evaluate and approve the services and fees of our independent auditors; to periodically review the auditors’ independence; and to assist our board of directors in fulfilling its oversight responsibilities by reviewing the financial information to be provided to the stockholders and others, the system of internal controls that management has established, and the audit and financial reporting process.

4

Compensation Committee

We have established a compensation committee to assist the board of directors in discharging its responsibility in all matters of compensation practices, including any salary and other forms of compensation for our officers and our directors, and employees in the event we ever have employees. Our compensation committee is comprised of our two independent directors, Jack Tompkins and Richard R. Ruskey. Our board of directors has adopted our Compensation Committee Charter and it is posted on Hartman’s web site at www.hi-reit.com. The primary duties of the compensation committee include reviewing all forms of compensation for our executive officers, if any, and our directors; approving all stock option grants, warrants, stock appreciation rights and other current or deferred compensation payable with respect to the current or future value of our shares; and advising on changes in compensation of members of the board of directors.

Nominating/Corporate Governance Committee

We have established a nominating committee. Our nominating committee is comprised of our two independent directors, Jack Tompkins and Richard R. Ruskey. Our board of directors has adopted our Nominating Committee Charter and it is posted on Hartman’s web site at www.hi-reit.com. The nominating committee will recommend nominees to serve on our board of directors. The nominating committee will consider nominees recommended by stockholders if submitted to the committee in accordance with the procedures specified in our bylaws. Generally, this requires that the stockholder send certain information about the nominee to our corporate secretary between 90 and 120 days prior to the first anniversary of the mailing of notice for the annual meeting held in the prior year. Because our directors take a critical role in guiding our strategic direction and oversee our management, board candidates must demonstrate broad-based business and professional skills and experiences, concern for the long-term interests of our stockholders, and personal integrity and judgment. In addition, directors must have time available to devote to board activities and to enhance their knowledge of our industry. The nominating committee is responsible for assessing the appropriate mix of skills and characteristics required of board members in the context of the perceived needs of the board at a given point in time and shall periodically review and recommend for approval by the board any updates to the criteria as deemed necessary. Diversity in personal background, race, gender, age and nationality for the board as a whole may be taken into account favorably in considering individual candidates. The nominating committee will evaluate the qualifications of each director candidate against these criteria in making its recommendation to the board concerning nominations for election or reelection as a director. The process for evaluating candidates recommended by our stockholders pursuant to our bylaws will be no different than the process for evaluating other candidates considered by the nominating committee.

4.

Certain Conflict Resolution Procedures

The following information supersedes and replaces in its entirety the section of our prospectus captioned” Conflicts of Interest – Certain Conflict Resolution Procedures- Our Acquisitions” beginning on page 84 of the prospectus:

5

Our Acquisitions. We will not purchase or lease properties in which our sponsor, our advisor, any of our directors or officers or any of their respective affiliates has an interest without a determination by a majority of the directors, including a majority of the independent directors, not otherwise interested in such transaction that such transaction is fair and reasonable to us and at a price to us no greater than the cost of the property to the seller or lessor unless there is substantial justification for any amount that exceeds such cost and such excess amount is determined to be reasonable. We will not sell or lease properties to our sponsor, our advisor, any of our directors or any of their respective affiliates unless a majority of the directors, including a majority of the independent directors, not otherwise interested in the transaction, determines the transaction is fair and reasonable to us. We expect that from time to time our advisor or its affiliates will temporarily enter into contracts relating to investment in properties and other assets all or a portion of which is to be assigned to us prior to closing or may purchase property or other investments in their own name and temporarily hold title for us. We may, however, purchase properties developed by affiliates of our advisor and our property manager. We will purchase properties from an affiliate at a price designed to afford such affiliate a reasonable profit, as approved by our independent directors, but in no case, at a price above the fair market value determined by our independent directors, and by an independent qualified appraiser where the transaction is with an affiliate of our sponsor, advisor or a director. Our independent directors may elect to determine the value of a property based on the application of an appropriate capitalization rate to the property’s net income or, in appropriate situations, recent sales prices of comparable properties or they may opt to require an independent appraisal of any such property. The independent directors will determine the appropriate capitalization rate under prevailing market conditions and whether and to what extent the sale of another property should be considered comparable in valuing one or more of our properties. Our conflict resolution guidelines present clear standards for the advisor to follow to determine which of the three Hartman affiliated REITs currently in business will have the first opportunity to purchase, finance or sell a property or to negotiate with a prospective tenant. In such an event, Hartman Advisors and HIR Management will offer properties to be developed to one of the other REITs first and will offer all other commercial rental properties to us first.

5.
