SECOND: The following amendments to the Articles of Incorporation were duly adopted by the board of directors on April 10, 1997, in accordance with Section 7-106-102 of the Colorado Business Corporation Act. Article Second of the Articles of Incorporation is hereby amended by adding the following provisions: 137,500 shares of the corporation's preferred stock shall consist of Series 1325 East 16th Avenue 9% Convertible Cumulative Preferred Stock (hereinafter referred to as "Series 1325 E. 16th Ave. Preferred Stock"). The rights, preferences, privileges and restrictions imposed upon the Series 1325 E. 16th Ave. Preferred Stock are as follows: (a) Dividends; Right to Dividends. The Series 1325 E. 16th Ave. Preferred Stock is entitled to receive, out of funds legally available therefor, dividends at the quarterly rate of up to $0.0225 per share and no more, to the extent that Rental Income, as defined below, is actually received by the corporation on the corporation's property located at 1325 East 16th Avenue, Denver, Colorado 80218 (the "Property"). Rental Income is defined as the net cash received as rental payments on the Property, less any expenses relating to the Property. Such dividend shall be paid in cash on or before the 90th day (the "Dividend Payment Date") after the last day of the quarter with respect to which such dividend shall be payable, which quarters shall begin on May 1, August 1, November 1 and February 1 of each year (a "Dividend Period"), commencing May 1, 1997. If any dividends payable on any share of Series 1325 E. 16th Ave. Preferred Stock shall not be paid for any reason, the right of the holder of such share of Series 1325 E. 16th Ave. Preferred Stock to receive payment of such dividend shall not lapse or terminate, but each such unpaid dividend (the "Unpaid Dividends") shall accumulate and shall be paid without interest to such holder to the extent that the Rental Income for those past Dividend Periods is received by the corporation and on the Dividend Payment Date for the Dividend Period when such past due Rental Income is actually received by the corporation. In the event that only a portion of the Rental Income due to the corporation is received by the corporation on the Property during any Dividend Period, holders of shares of Series 1325 E. 16th Ave. Preferred Stock shall be entitled to receive their pro rata share of dividends based upon the Rental Income actually received by the corporation during that Dividend Period. In the event that the Property is sold, transferred, assigned or conveyed (a "Transfer") by the corporation, the holders of shares of Series 1325 E. 16th Ave. Preferred Stock shall not be entitled to any further dividends after the effective date of the Transfer. The corporation's determination of Rental Income on the Property shall be audited on an annual basis at the corporation's expense as part of the corporation's fiscal year end audit by an independent certified public accountant to determine that the corporation's determination of Rental Income has been calculated in accordance with generally accepted accounting principals. All such dividends shall accrue from the date of issuance whether or not earned so that no dividends or other distributions shall be made by the corporation with respect to the common stock, and no common stock shall be purchased or redeemed by the corporation, unless and until all Unpaid Dividends on the Series 1325 E. 16th Ave. Preferred Stock for all past Dividend Periods and for the then current Dividend Period shall have been declared and paid or set aside for payment. After all Unpaid Dividends on the Series 1325 E. 16th Ave. Preferred Stock for all past Dividend Periods and for the then current Dividend Period shall have been declared and paid or set aside for payment, if the board of directors shall declare dividends out of funds legally available therefor, such additional dividends may be declared on the common stock. (b) Liquidation and Dissolution. Upon the voluntary or involuntary liquidation, winding up or dissolution of the corporation, out of the assets available for distribution to shareholders whether such assets are capital, surplus or earnings, each share of Series 1325 E. 16th Ave. Preferred Stock shall be entitled to receive, in preference to any payment on the common stock only, an amount equal to $1.00 per share, plus cumulative dividends as provided in paragraph (a) of this Article Second accrued and unpaid to the date payment is made available to the Series 1325 E. 16th Ave. Preferred Stock. After the full preferential liquidation amount has been paid to, or determined and set apart for, Series 1325 E. 16th Ave. Preferred Stock, the remaining assets shall be payable to the holders of the common stock. In the event the assets of the corporation are insufficient to pay the full preferential liquidation amount required to be paid to the Series 1325 E. 16th Ave. Preferred Stock, the Series 1325 E. 16th Ave. Preferred Stock shall receive such funds pro rata on a share for share basis until the full liquidating preference on the Series 1325 E. 16th Ave. Preferred Stock is paid in full, and the balance, if any, shall then be paid to the holders of common stock. A reorganization shall not be considered to be a liquidation, winding up or dissolution within the meaning of this paragraph (b) of this Article Second and the Series 1325 E. 16th Ave. Preferred Stock shall be entitled only to the rights provided in the plan of reorganization. (c) Voting. Holders of shares of Series 1325 E. 16th Ave. Preferred Stock shall not be entitled to voting rights on any matter other than upon those matters set forth in Section 7-110-104 of the Colorado Business Corporation Act.

(ii) Mechanics of Conversion. Before any holder of shares of Series 1325 E. 16th Ave. Preferred Stock shall be entitled to convert the same into full shares of common stock pursuant to paragraph (e)(i) of this Article Second, the holder shall surrender the certificate or certificates therefor, duly endorsed, at the office of the corporation or of any transfer agent for such Series 1325 E. 16th Ave. Preferred Stock, as the case may be, and shall give written notice to the corporation at such office that the holder elects to convert the same and shall state therein the holder's name or the name or names of the holder's nominees in which the holder wishes the certificate or certificates for shares of common stock to be issued. The corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder, or to the holder's nominee or nominees, a certificate or certificates for the number of full shares of common stock to which the holder shall be entitled as aforesaid. A conversion pursuant to paragraph (e)(i) of this Article Second shall be deemed to have occurred immediately prior to the close of business on the date of such surrender of the shares of Series 1325 E. 16th Ave. Preferred Stock to be converted, and the person or persons entitled to receive the shares of common stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of common stock on such date.

(3) Adjustment for Certain Dividends and Distributions. In the event the corporation at any time, or from time to time, after the Original Issue Date applicable to Series 1325 E. 16th Ave. Preferred Stock shall make or issue, or fix a record date for the determination of holders of common stock entitled to receive, a dividend or other distribution payable in shares of common stock, then and in each such event the applicable Conversion Price then in effect shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Conversion Price then in effect by a fraction: a) the numerator of which shall be the total number of shares of common stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and b) the denominator of which shall be the total number of shares of common stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of common stock issuable in payment of such dividend or distribution; provided, however, if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Conversion Price shall be recomputed accordingly as of the close 5 of business on such record date and thereafter such Conversion Price shall be adjusted pursuant to this paragraph (e)(iii)(3) of this Article Second as of the time of actual payment of such dividends or distributions. (4) Adjustment for Other Dividend and Distributions. In the event the corporation at any time or from time to time after the Original Issue Date of Series 1325 E. 16th Ave. Preferred Stock shall make or issue, or fix a record date for the determination of holders of common stock entitled to receive, a dividend or other distribution payable in securities of the corporation other than shares of common stock, then and in such event provisions shall be made so that the holders of Series 1325 E. 16th Ave. Preferred Stock shall receive upon conversion thereof, in addition to the number of shares of common stock receivable thereupon, the amount of securities of the corporation which they would have received had their Series 1325 E. 16th Ave. Preferred Stock been converted into common stock on the date of such event and had thereafter, during the period from the date of such event to and including the conversion date, retained such securities (together with any distributions payable thereon during such period) receivable by them as aforesaid during such period, giving application to all adjustments called for during such period under paragraph (e) of this Article Second with respect to the rights of the holders of the Series 1325 E. 16th Ave. Preferred Stock.
