As Representative of the Several Underwriters 300 Plaza Level 1675 Larimer Street Denver, Colorado 80202 Gentlemen: We confirm our agreement among you, the undersigned and the other prospective Underwriters named in Schedule I to the Underwriting Agreement with respect to the purchase, severally, from Cavion Technologies, Inc., a Colorado corporation (the "Company"), of an aggregate of 1,200,000 shares (the "Firm Shares") of the Company's common stock, $.0001 par value per share (the "Common Stock"). In addition, the Company has granted to the Underwriters an option to purchase from the Company up to an aggregate of 180,000 additional shares of Common Stock (the "Option Shares") for the sole purpose of covering over-allotments in the sale of the Firm Shares upon the terms and conditions stated in the Underwriting Agreement. Unless otherwise defined herein, capitalized terms in this Agreement shall have the meanings given to such terms in the Underwriting Agreement. We agree in accordance with the terms hereof and the Underwriting Agreement to purchase the number of Firm Shares set forth opposite our names in Schedule I to the Underwriting Agreement and to purchase Option Shares in the same proportion as the number of our Firm Shares is to the 1,200,000 shares of Common Stock. The Firm Shares and any Option Shares purchased under the Underwriting Agreement are hereinafter sometimes collectively called the "Securities." We confirm that our net capital and ratio of aggregate indebtedness to net capital are such that we may, in accordance with and pursuant to Rule 15c3-1, promulgated by the Securities and Exchange Commission (the "Commission") under the Securities Exchange Act of 1934 (the "1934 Act") and agree to purchase the number of Securities set forth opposite our names in Schedule I to the Underwriting Agreement (together with any increase in such number provided for herein or in the Underwriting Agreement). We are familiar with Rule 15c2-8 promulgated by the Commission under the 1934 Act relating to the distribution of preliminary and final prospectuses and confirm that we have complied and will comply therewith. You hereby confirm that you will make available to each Underwriter, from time to time, such number of copies of the Preliminary Prospectus and Prospectus (as amended or supplemented) as such underwriter may reasonably request for the purposes contemplated by the Securities Act of 1933, as amended (the "1933 Act") or the 1934 Act, or the applicable rules and regulations of the Commission thereunder. SECTION 1. AUTHORITY OF THE REPRESENTATIVE. We authorize you, as our Representative, (a) to execute and deliver the Underwriting Agreement on our behalf in substantially the form annexed hereto as Exhibit A, with such changes as in your judgment are advisable or appropriate, including but not limited to increases or decreases in the number of Securities to be purchased hereunder, and changes in those who are to be Underwriters and in the respective number of Securities to be purchased by them (but not any increase in the number of Securities to be purchased by us except with our consent or as provided in this Agreement and the Underwriting Agreement), (b) to exercise all the authority and discretion vested in the Underwriters and in you by the provisions of the Underwriting Agreement and (c) to take such other action as you deem advisable or appropriate in connection with the performance of this Agreement and the Underwriting Agreement and the purchase, carrying, sale and distribution of the Securities, except that, without the consent of a majority in interest of the Underwriters (including yourselves), you shall not consent to any extension of more than 24 hours of the time provided in Section 9(x) of the form of Underwriting Agreement within which the Registration Statement shall have become effective. SECTION 2. SALE TO THE PUBLIC. It is expected that the sale of the Securities to the public will commence as soon in your judgment as advisable after the Registration Statement has become effective. We will not sell any Securities until they are released by you for that purpose. The initial public advertisement will appear on such date and will include the name of such of the Underwriters as you may determine. Thereafter any Underwriter may advertise at its own risk and expense. SECTION 3. OFFERING TO SELECTED DEALERS AND OTHERS. We authorize you, for our account, to reserve and offer for sale and sell such number of Securities to be purchased by us as you shall determine to dealers (the "Selected Dealers"), among whom any of the Underwriters may be included, who shall be members of the National Association of Securities Dealers, Inc. ("NASD"), or foreign dealers who are not eligible for membership in the NASD and which foreign dealers agree to make no sales of the Securities within the United States, its territories or its possessions or to persons who are nationals thereof or residents therein and, in making such sales, to comply with the requirements of the Conduct Rules of the NASD (including Rules 2730, 2740, and 2750, and Rule 2420 as that Rule applies to non- member foreign dealers) and the Interpretation of the Board of Governors of the NASD with respect to Free-riding and Withholding. Such offering may be made under a Selected Dealer Agreement substantially in the form attached hereto (the "Selected Dealer Agreement") or otherwise. The price to Selected Dealers shall be the public offering price less a concession to be determined by you of not in excess of 50% of the difference between the initial public offering price of the Securities and the purchase price to be paid by the Underwriters for the Securities. We also authorize you, for our account, to reserve and offer for sale and sell Securities to be purchased by us, at the public offering price, to institutions or other retail purchasers other than Selected Dealers. Such reservations and sales to others shall be as nearly as practicable in proportion to our underwriting obligation, unless you agree to a smaller proportion at our request. At or before the time of the public offering you will advise us of the number of Securities to be purchased by us which have not been reserved for sale as provided in this Section. Sales to Selected Dealers shall be made as nearly as practicable in the ratio which the number of Securities reserved for our account bears to the aggregate number of Securities reserved for the account of all Underwriters, as evaluated from day to day. You may deliver to any of the Underwriters from time to time, (i) for earning purposes, or (ii) for sale by such Underwriter, any of the Securities then reserved for offering and sale to, but not purchased and paid for by, Selected Dealers or others as above provided; but to the extent that Securities are so delivered for sale by such Underwriter, the number of Securities then reserved for the account of such Underwriter shall be correspondingly reduced. Securities delivered for carrying purposes only must be redelivered to you upon your demand We will repurchase any Securities sold by us, except through you, which shall be contracted for or purchased by you in the open market during the life of this Agreement or within seven days after the termination thereof, on demand, at a price equal to the cost of such purchase plus tax on redelivery and commission, if any. In lieu thereof you may, in your discretion, (i) sell the same for our account at such prices and upon such terms and to such persons, including any of the other Underwriters, as you may determine, charging the amount of any loss and expense or crediting the amount of any profit, less any expense, resulting from such sale, to our account, or (ii) charge our account with an amount not in excess of the concession to Selected Dealers on such Securities, plus commissions and taxes paid in connection with such purchase. Each Underwriter agrees that if any such offering is made pursuant to a Selected Dealer Agreement, it will be governed by the terms and provisions thereof. SECTION 4. PAYMENT AND DELIVERY; SETTLEMENT OF ACCOUNT.

We authorize you for our account to make payment of the purchase price of the Securities which we have agreed to purchase against delivery to you of such Securities, and the difference between the purchase price of the Securities which we have agreed to purchase and an amount equal to the initial public offering price less the selling concession in respect of the number of Securities which we have agreed to purchase shall be credited to our account. You may, in your discretion, make payment of the purchase price on our behalf and, if we are a member of, or clear through a member of, the Depository Trust Company ("DTC") you may, in your discretion, deliver our Securities through the facilities of DTC.
