Conversion Procedures. The holder of any shares of 1993 Series C --------------------- Preferred Stock may exercise such holder's optional right to convert such shares into shares of common Stock by Page 11 surrendering for such purpose to the Corporation, at its principal office or at such other office or agency maintained by the Corporation for that purpose, a certificate or certificates representing the shares of 1993 Series C Preferred Stock to be converted accompanied by a written notice stating that such holder elects to convert all or a specified whole number of such shares in accordance with the provisions of this Section 7 and specifying the number or names in which such holder wishes the certificate or certificates for shares of Common Stock to be issued. In case such notice shall specify a name or names other than that of such holder, such notice shall be accompanied by payment of all transfer taxes payable upon the issuance of shares of Common Stock in such name or names. Other than such taxes, the Corporation will pay any and all issue and other taxes (other than taxes based on income) that may be payable in respect to any issue or delivery of shares of Common Stock on conversion of 1993 Series C Preferred Stock pursuant hereto.

The Corporation shall not be required to convert, and no surrender of shares of 1993 Series C Preferred Stock shall be effective for that purpose, while the transfer books of the Corporation for the Common stock are closed or any purpose (but not for any period in excess of 15 calendar days); but the surrender of shares of 1993 Series C Preferred Stock for conversion during any period while such books are so closed shall become effective for conversion immediately upon the reopening of such books, as if the conversion had been made on the date such shares of 1993 Series C Preferred Stock were surrendered, and at the conversion rate in effect at the date of such surrender. Page 13 7.8. Payment of Accrued Dividends Upon Conversion.

The Corporation shall from time to time, subject to and in accordance with the law of the state of Colorado, increase the authorized amount of Common Stock if at any time the number of authorized shares of Common Stock remaining unissued shall not be sufficient to permit the Page 14 conversion at such time of all then outstanding shares of 1993 Series C Preferred Stock. 9. CANCELLATION OF CONVERTED SHARES -------------------------------- All shares of 1993 Series C Preferred Stock converted pursuant to Section 7 shall be canceled and shall not be issuable by the Corporation, and the Articles of Incorporation shall be appropriately amended, if required, to effect the corresponding reduction in the Corporation's authorized capital. 10. NOTICES OF RECORD DATE ---------------------- In the event of any taking by the Corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, the Corporation shall mail to each holder of 1993 Series C Preferred Stock, at least twenty (20) days prior to the date specified herein, a notice specifying the date on which any such record is to be taken for the purposes of such dividend or distribution. 11.

The fair value of any consideration other than cash will be determined jointly by the Company and the holders of a majority of the outstanding Series B Preferred Stock. If such parties are unable to reach agreement within a reasonable period of time, the fair value of such consideration will be determined by an appraiser jointly selected by the Company and the holders of a majority of the outstanding Series B Preferred Stock. The cost of such appraisers shall be borne by the Company. 6.6.1.3 In the case of the issuance of (a) options to purchase or rights to subscribe for Common Stock (other than Excluded Stock), (b) securities by their terms convertible into or exchangeable for Common Stock (other than Excluded Stock), or (c) options to purchase or rights to subscribe for such convertible or exchangeable securities: (i) The aggregate maximum number of shares of Common Stock deliverable upon exercise of such options to purchase or rights to subscribe upon exercise of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Sections 6.6.1.1 and 6.6.1.2 above), if any, received by the Company upon the issuance of such options, or rights plus the minimum purchase price provided in such options or rights for the Common Stock covered thereby; (ii) The aggregate maximum number of shares of Common Stock deliverable upon conversion of or in exchange for any such convertible or exchangeable securities, or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof, shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration received by the Company for any such securities and related options of rights (excluding any cash received on account of accrued interest, or accrued dividends), plus the additional consideration, if any, to be received by the Company upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in Sections 6.6.1.1 and 6.6.1.2 -4- 6.6.2 "Excluded Stock" shall mean: 6.6.2.1 All shares of Common Stock issued and outstanding as of the date hereof; 6.6.2.2 All shares of Common Stock that may be issued pursuant to the conversion of three convertible notes dated April 30, 1986, in the aggregate principal amount of One hundred Fifty Thousand Dollars ($150,000) (the "Convertible Notes"); 6.6.2.3 All shares of Common Stock into which the Series A Preferred Stock and this Series s Preferred Stock are convertible; 6.6.2.4 All shares of Common Stock that may be issued pursuant to the exercise of warrants held by the limited partners of IMS Rental Partners, Ltd., a Colorado Limited Partnership; 6.6.2.5 An aggregate of 50,000 shares of Common Stock that may be issued to Columbia Group, Ltd. pursuant to an agreement dated August 11, 1986; and 6.6.2.6 An aggregate of 450,000 shares of Common Stock issued or to be issued under any employee, consultant or director incentive arrangement or plan adopted by the Company's Board of Directors for an exercise price of not less than $1.00 per share, including, without limitation, the Company "1986 Incentive Stock Option Plan." 6.6.2.7 An aggregate of 240,000 shares of Common Stock issued or to be issued to Welsh, Carson, Anderson & Stowe IV and affiliated purchasers for consideration of $1.25 per share.
