NOW, THEREFORE, in consideration of the promises and the mutual agreements hereinafter set forth, it is agreed that: 1. WARRANT/WARRANT CERTIFICATES. Each Warrant shall entitle the holder (the "Registered Holder" or, in the aggregate, the "Registered Holders") in whose name the Warrant Certificate shall be registered on the books maintained by the Warrant Agent to purchase one share of Common Stock of the Company on exercise thereof, subject to modification and adjustment as provided in Section 8. Warrant Certificates representing the right to purchase Warrant Shares shall be executed by the Company's President and attested to by the Company's Secretary or Assistant Secretary and delivered to the Warrant Agent upon execution of this Agreement. Subject to the provisions of Sections 3, 6 and 7, the Warrant Agent shall deliver Warrant Certificates in required whole number denominations to Registered Holders in connection with any transfer or exchange permitted under this Agreement. Except as provided in Section 7 hereof, no Warrant Certificates shall be issued except (i) Warrant Certificates initially issued hereunder, (ii) Warrant Certificates issued on or after the initial issuance date, upon the exercise of any Warrants, to evidence the unexercised Warrants held by the exercising Registered Holder, and (iii) Warrant Certificates issued after the initial issuance date, upon any transfer or exchange of Warrant Certificates or replacements of lost or mutilated Warrant Certificates. 2. FORM AND EXECUTION OF WARRANT CERTIFICATES. The Warrant Certificates shall be substantially in the form attached as Exhibit A. The Warrant Certificates shall be dated as of the date of their issuance, whether on initial issuance, transfer or exchange or in lieu of mutilated, lost, stolen or destroyed Warrant Certificates. Each such Warrant Certificate shall be numbered serially in accordance with the Common Stock initially attached thereto with the letter "WA" appearing on each "Warrant Certificate. The Warrant Certificates may immediately be detached, and, in such event, the Warrant Certificates may be issued by number preceded by the letter "WA" without regard to the number of the certificate representing the Common Stock initially attached thereto. The Warrant Certificates shall be manually countersigned by the Warrant Agent and shall not be valid for any purpose unless so countersigned. In the event any officer of the Company who executed the Warrant Certificates shall cease to be an officer of the Company before the date of issuance of the Warrant Certificates or before countersignature and delivery by the Warrant Agent, such Warrant Certificates may be countersigned, issued and delivered by the Warrant Agent with the same force and effect as though the person who signed such Warrant Certificates had not ceased to be an officer of the Company. 3. EXERCISE. Subject to the provisions of Sections 5 and 8, the Warrants, when evidenced by a Warrant Certificate, may be exercised at a price (the "Exercise Price") of $_______ per share of Common Stock in whole or in part at any time during the period (the "Exercise Period") commencing upon the Effective Date of the Registration Statement to be filed by the Company for sale under the Securities Act of 1933, as amended (the "Securities Act") the Warrants and Warrant Shares (the "Exercise Date"), and ending at 5:00 o'clock p.m. Mountain Time on the _____ day of _______________, 2003 ("Expiration Date") The Company shall promptly notify the Warrant Agent of any such extension of the Exercise Period. A Warrant shall be deemed to have been exercised immediately prior to the close of business on the date (the "Exercise Date") of the surrender for exercise of the Warrant Certificate. The exercise form shall be executed by the Registered Holder thereof or his attorney duly authorized in writing and will be delivered together with payment to the Warrant Agent at its corporate offices located at 370 17th Street, Suite 2350, Denver, Colorado 80202 (the "Corporate Office"), in cash or by official bank or certified check, of an amount equal to the aggregate Exercise Price, in lawful money of the United States of America. Unless Warrant Shares may not be issued as provided herein, the person to receive the number of Warrant Shares deliverable on such exercise shall be treated for all purposes as the holder of such Warrant Shares as of the close of business on the Exercise Date. Upon the receipt of any Warrant for exercise as set forth herein, the Warrant Agent shall promptly verbally notify the Company, with confirmation in writing of such fact, of the name and address of the exercising Registered Holder and of the number of Warrant Shares to be delivered upon such exercise. In addition, the Warrant Agent shall also, at such time, verify that all of the conditions precedent to the issuance of Warrant Shares set forth in Section 5 have been satisfied as of the Exercise Date. If any one of the conditions set forth in Section 5 are not satisfied as of the Exercise Date, the Warrant Agent shall request written instructions from the Company as to whether to return the Warrant and Exercise Price to the exercising Registered Holder or to hold the same until all such conditions have been satisfied. The Company shall not be obligated to issue any fractional shares interests in Warrant Shares issuable or deliverable on the exercise of any Warrant or scrip or cash therefore and such fractional shares shall be of no value whatsoever. If more than one Warrant shall be exercised at one time by the same Registered Holder, the number of full Shares which shall be issuable on exercise thereof shall be computed on the basis of the aggregate number of full shares issuable on such exercise. Within thirty (30) days after the Exercise Date and in any event prior to the Expiration Date, pursuant to a Stock Transfer Agreement dated July 5, 1991, between the Company and Warrant Agent, the Warrant Agent shall cause to be issued and delivered to the person or persons entitled to receive the same, a certificate or certificates for the number of Warrant Shares deliverable on such exercise. No -2- adjustment shall be made in respect of cash dividends on Warrant Shares delivered on exercise of any Warrant. The Warrant Agent shall promptly notify the Company in writing of any exercise and of the number of Warrant Shares delivered and shall cause payment of an amount in cash equal to the Exercise Price to be promptly made to the order of the Company. The parties contemplate such payments will be made by the Warrant Agent to the Company on a weekly basis and will consist of collected funds only. The Warrant Agent shall hold any proceeds collected and not yet paid to the Company in a federally insured account at all times relevant hereto. The Company may deem and treat the Registered Holder of the Warrants at any time as the absolute owner thereof for all purposes, and the Company shall not be affected by any notice to the contrary. The Warrants shall not entitle the holder thereof to any of the rights of shareholders or to any dividend declared on the Common Stock unless the holder shall have exercised the Warrants and purchased the shares of Common Stock prior to the record date fixed by the Board of Directors of the Company for the determination of holders of Common Stock entitled to such dividend or other right. 4. RESERVATION OF SHARES AND PAYMENT OF TAXES. The Company covenants that it will at all times reserve and have available from its authorized Common Stock such number of shares as shall then be issuable on the exercise of all outstanding Warrants. The Company covenants that all Warrant Shares which shall be so issuable shall be duly and validly issued, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issue thereof. The Company and the Warrant Agent acknowledge that the Company will be required, pursuant to the Securities Act, to deliver to each Registered Holder, upon the exercise of Warrants and delivery of Warrant Shares, a prospectus covering the issuance of the Warrant Shares which meets the requirements of the Act, which prospectus must be a part of an effective registration statement under the Act at the time that the Warrant is exercised. No Warrants may be exercised nor may Warrant shares be issued by the Company's transfer agent or delivered by the Warrant Agent unless, on the Exercise Date: (i) the Company has an effective registration statement covering the issuance of the Warrant Shares under the Act; (ii) the Warrant Agent has copies of the prospectus which is a part of such effective registration statement and which the Warrant Agent hereby agrees to deliver with the Warrant Shares; and (iii) the Warrant Shares may legally be issued and delivered to the exercising Registered Holder under the securities laws of the state in which such Registered Holder resides. The Company agrees to maintain, to the extent required by the Act, an effective registration statement under the Act covering the issuance of the Warrant Shares during the period the Warrants are exercisable. The Company further agrees, from time to time, to furnish the Warrant Agent with copies of the Company's prospectus to be delivered to exercising Registered Holders, as set forth above. If any shares of Common Stock to be reserved for the purpose of exercise of Warrants hereunder require any other registration with or approval of any government authority under any federal or state law before such shares may be validly issued or delivered, then the Company covenants that it will secure such registration or approval, as the case may be. No Warrant Shares shall be issued unless and until any such registration requirements have been satisfied. The Registered Holder shall pay all documentary, stamp or similar taxes and other government charges that may be imposed with respect of the issuance of the Warrants, or the issuance, -3- transfer or delivery of any Warrant Shares on exercise of the Warrants. In the event the Warrant Shares are to be delivered in a name other than the name of the Registered Holder of the Warrant Certificate, no such delivery shall be made unless the person requesting the same has paid to the Warrant Agent the amount of any such taxes or charges incident thereto. In the event the Warrant Agent ceases to also serve as the stock transfer agent for the Company, the Warrant Agent is irrevocably authorized to requisition the Company's new transfer agent from time to time for Certificates of Warrant Shares required upon exercise of the Warrants, and the Company will authorize such transfer agent to comply with all such requisitions. The Company will file with the Warrant Agent a statement setting forth the name and address of its new transfer agent, for shares of Common Stock or other capital stock issuable upon exercise of the Warrant and of each successor transfer agent. 5. REGISTRATION OF TRANSFER. The Warrant Certificates may be transferred in whole or in part. Warrant Certificates to be exchanged shall be surrendered to the Warrant Agent at its Corporate Office. The Company shall execute and the Warrant Agent shall countersign, issue and deliver in exchange therefor the Warrant Certificate or Certificates which the holder making the transfer shall be entitled to receive. The Warrant Agent shall keep transfer books at its Corporate Office which shall register Warrant Certificates and the transfer thereof. On due presentment for registration of transfer of any Warrant Certificate at such office, the Company shall execute and the Warrant Agent shall issue and deliver to the transferee or transferees a new Warrant Certificate or Certificates representing an equal aggregate number of Warrants. All Warrant Certificates presented for registration of transfer or exercise shall be duly endorsed or be accompanied by a written instrument or instruments or transfer in form satisfactory to the Company and the Warrant Agent.

Prior to due presentment for registration of transfer thereof, the Company and the Warrant Agent may treat the Registered Holder of any Warrant Certificate as the absolute owner thereof (notwithstanding any notations of ownership or writing thereon made by anyone other than the Company or the Warrant Agent), and the parties hereto shall not be affected by any notice to the contrary. 6. LOSS OR MUTILATION. On receipt by the Company and the Warrant Agent of evidence satisfactory as to the ownership of and the loss, theft, destruction or mutilation of any Warrant Certificate, the Company shall execute, and the Warrant Agent shall countersign and deliver in lieu thereof, a new Warrant Certificate representing an equal aggregate number of Warrants.

In the event a Warrant Certificate is mutilated, such Certificate shall be surrendered and cancelled by the Warrant Agent prior to delivery of a new Warrant Certificate. Applicants for a new Warrant Certificate shall also comply with such other regulations and pay such other reasonable charges as the Company may prescribe. -4- 7. REDEMPTION. The Company shall have the right to redeem any or all outstanding and unexercised Warrants evidenced by this Certificate at a redemption price of $0.25 per Warrant upon thirty (30) days' written notice in the event (i) a Registration Statement registering for sale under the Securities Act the shares of the Company's Common Stock issuable upon exercise of the Warrant, has been filed with the Securities and Exchange Commission and is in effect on the date of written notice and the redemption date contained therein, (ii) there has been developed and exists on the date of written notice a public trading market for the Company's Common Stock and such shares are listed for quotation on the NASDAQ Stock Market or OTC Electronic Bulletin Board, and (iii) the public trading price of the Company's Common Stock has equaled or exceeded $_______ per share (200% of the Warrant Exercise Price) for ten (10) or more consecutive trading days.

The holders of the Warrants called for redemption shall have the right to exercise the Warrants evidenced hereby until the close of business on the date next preceding the date fixed for redemption. On or after the date fixed for redemption, the holder hereof shall have no rights with respect to this Warrant except the right to receive $0.25 per Warrant upon surrender of this Certificate. 8. ADJUSTMENT OF EXERCISE PRICE AND SHARES. After each adjustment of the Exercise Price pursuant to this Section 8, the number of shares of Common Stock purchasable on the exercise of Warrant shall be the number derived by dividing such adjusted Exercise Price into the original Exercise Price. The Exercise Price shall be subject to the adjustment as follows: (a) In the event, prior to the expiration of the Warrants by exercise or by their terms, the Company shall issue any shares of its Common Stock as a share dividend or shall subdivide the number of outstanding shares of Common Stock into a greater number of shares, then, in either of such events, the Exercise Price per share of Common Stock purchasable pursuant to the Warrants in effect at the time of such action shall be reduced proportionately and the number of shares purchasable pursuant to the Warrants shall be increased proportionately. Conversely, in the event the Company shall reduce the number of shares of its outstanding Common Stock by combining such shares into a smaller number of shares, then, in such event, the Exercise Price per share purchasable pursuant to the Warrants in effect at the time of such action shall be increased proportionately and the number of shares of Common Stock at that time purchasable pursuant to the Warrants shall be decreased proportionately. Any dividend paid or distributed on the Common Stock in shares of any other class of the Company or securities convertible into shares of Common Stock shall be treated as a dividend paid in Common Stock to the extent that shares of Common Stock are issuable on the conversion thereof. (b) In the event the Company, at any time while the Warrants shall remain unexpired and unexercised, shall sell all or substantially all of its property, or dissolves, liquidates or winds up its affairs, prompt, proportionate, equitable, lawful and adequate provision shall be made as part of the terms of any such sale, dissolution, liquidation or winding up such that the holder of a Warrant may thereafter receive, on exercise thereof, in lieu of each share of Common Stock of the Company which he would have been entitled to receive, the same kind and amount of any share, securities, or assets as may be issuable, distributable or payable on any such sale, dissolution, liquidation or winding up with respect to each share of Common Stock of the Company; provided, however, that in the event of any such sale, dissolution, liquidation or winding up, the right to exercise this Warrant shall terminate on a date fixed by the Company, such date to be not earlier than 5:00 p.m., Mountain Time, on the 30th day next succeeding the date on which notice of such termination of the right to exercise the Warrants has been given by mail to the holders thereof at such addresses as may appear on the books of the Company. -5- (c) Notwithstanding the provisions of this Section 8, no adjustment on the Exercise Price shall be made whereby such Price is adjusted in an amount less than $.01 or until the aggregate of such adjustments shall equal or exceed $.01. (d) In the event, prior to the expiration of the Warrants by exercise or by their terms, the Company shall determine to take a record of the holders of its Common Stock for the purpose of determining shareholders entitled to receive any share dividend or other right which will cause any change or adjustment in the number, amount, price or nature of the share of Common Stock or other, securities or assets deliverable on exercise of the Warrants pursuant to the foregoing provisions, the Company shall give to the Registered Holders of the Warrants at the addresses as may appear on the books of the Company at least thirty (30) days' prior written notice to the effect that it intends to take such a record. Such notice shall specify the date as of which such record is to be taken; the purpose for which such record is to be taken; and the number, amount, price and nature of the Common Shares or other shares, securities or assets which will be deliverable on exercise of the Warrants after the action for which such record will be taken has been completed. Without limiting the obligation of the Company to provide notice to the Registered Holders of the Warrant Certificates of any corporate action hereunder, the failure of the Company to give notice shall not invalidate such corporate action of the Company. (e) No adjustment of the Exercise Price shall be made as a result of or in connection with (i) the issuance of Common Stock of the Company pursuant to options, warrants and share purchase agreements outstanding or in effect on the date hereof, (ii) the establishment of additional option plans of the Company, the modification, renewal or extension of any plan now in effect or hereafter created, or the issuance of Common Stock on exercise of any options pursuant to such plans, or (iii) the issuance of Common Stock in connection with an acquisition or merger of any type (therefore the anti-dilution provisions of this Section 8 will not apply in the event a merger or acquisition is undertaken by the Company), in connection with compensation arrangements for officers, employees or agents of the Company or any subsidiary, and the like. (f) This Warrant Agent Agreement shall be incorporated by reference on the Warrant Certificates. Before taking any action which would cause an adjustment reducing the Exercise Price below the then par value of the shares of Common Stock issuable upon exercise of the Warrants, the Company will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of such Common Stock at such adjusted Exercise Price. Upon any adjustment of the Exercise Price required to be made pursuant to this Section 8, the Company within 30 days thereafter shall (A) cause to be filed with the Warrant Agent a certificate setting forth the Exercise Price after such adjustment and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, and (B) cause to be mailed to each of the Registered Holders of the Warrant Certificates written notice of such adjustment. 9. DUTIES, COMPENSATION AND TERMINATION OF WARRANT AGENT. The Warrant Agent shall act hereunder as agent and in a ministerial capacity for the Company, and its duties shall be determined solely by the provisions hereof.

The Warrant Agent may at any time consult with counsel satisfactory to it (which may be counsel for the Company) and shall incur no liability or responsibility for any action taken or omitted by it in good faith in accordance with the opinion or advice of such counsel. Any notice, statement, instruction, request, direction, order or demand of the Company shall be sufficiently evidenced by an instrument signed by its President and attested by its Secretary or Assistant Secretary.

The Warrant Agent may resign its duties or the Company may terminate the Warrant Agent and the Warrant Agent shall be discharged from all further duties and liabilities hereunder (except liabilities arising as a result of the Warrant Agent's own negligence or willful misconduct), on 30 days' prior written notice to the other party. At least 15 days prior to the date such resignation is to become effective, the Warrant Agent shall cause a copy of such notice of resignation to be mailed to the Registered Holder of each Warrant Certificate. On such resignation or termination the Company shall appoint within a period of 30 days after it has been notified in writing of the registration by the Warrant Agent, then the Registered Holder of any Warrant Certificate may apply to any court of competent jurisdiction for the appointment of a new warrant agent. Any new warrant agent, whether appointed by the Company or by such court, shall be a bank or trust company having a capital and surplus, as shown by its last published report to its shareholders, of not less than $1,000,000, and having its principal office in the State of Colorado. -7- After acceptance in writing of an appointment of a new warrant agent is received by the Company, such new warrant agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the Warrant Agent, without further assurance, conveyance, act or deed; provided, however, if it shall be necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the expense of the Company and shall file a notice of appointment of a new warrant agent with the resigning Warrant Agent and shall forthwith cause a copy of such notice to be mailed to the Registered Holder of each Warrant Certificate. Any corporation into which the Warrant Agent or any new warrant agent may be converted or merged, or any corporation resulting from any consolidation to which the Warrant Agent or any new warrant agent shall be a party, or any corporation succeeding to the corporate trust business of the Warrant Agent shall be a successor Warrant Agent under this Agreement, provided that such corporation is eligible for appointment as a successor to the Warrant Agent under the provisions of the preceding paragraph.
