Ladies and Gentlemen:

The undersigned understands that Sento Corporation, a Utah corporation (the "Company"), in accordance with the terms and conditions of this Subscription Agreement (the "Agreement"), is offering for sale up to 1,500 units (the "Units") each consisting of (i) one $990 face amount 8% convertible subordinated debenture (a "Debenture"), each convertible into 565.714 shares of the common stock, par value $0.25 per share, of the Company (the "Common Stock"), at an initial conversion price of $1.75 per share (each share issuable upon conversion thereof being a "Conversion Share"), at any time after the first anniversary and prior to the third anniversary of the closing of the Offering (as defined below) (the date of such closing being the "Closing Date" and the date of such third anniversary being the "Expiration Date"), together with (ii) two hundred fifty common stock purchase warrants (each such warrant being a "Warrant") each for the purchase of one share of the Common Stock (upon issue thereof, a "Warrant Share"), exercisable until the Expiration Date at an exercise price of $2.25 per Warrant Share (the "Offering"). The Company is offering the Units at a price of $1,000 per Unit. There is no minimum number of Units which must be subscribed for by any one purchaser. The Units are being offered on a "best efforts" basis and there is no requirement for a minimum amount of subscriptions. The Units are being offered for sale pursuant to a Private Placement Memorandum dated March 10, 2003, as amended by the First Amendment and Supplement thereto dated March 25, 2003 (together referred to as the "Memorandum"), as more particularly described and set forth therein. Unless otherwise indicated, terms used herein shall have the same meanings as set forth in the Memorandum.

1. Acquisition of Units. Subject to the terms and conditions hereof and the provisions of the Memorandum, the undersigned hereby irrevocably subscribes for and agrees to purchase the number of Units indicated in Item 8 on page 8 of this Agreement at a purchase price of $1,000 per Unit, or an aggregate purchase price equal to the amount indicated in Item 9 on page 8 of this Agreement.

2. Acceptance of Subscription. The undersigned understands and agrees that the Company shall have the right to accept or reject this subscription, in whole or in part, and that the same shall be deemed to be accepted by the Company only when this Agreement is accepted and signed by a duly authorized officer of the Company as provided for herein. Subscriptions need not be accepted in the order received, and the Units may be allocated in whole or in part, at the sole discretion of the Company, in the event of an oversubscription.

The Units are being offered on a "best efforts" basis, and there is no requirement for the sale of a minimum amount of Units. There is no assurance that the Company will be able to sell all or any

portion of the Units, and the number of Units which will actually be sold by the Company in the Offering is unknown. Once subscriptions are received by the Company, investors will be irrevocably bound by the terms thereof.

3. Representations, Warranties and Covenants of the Undersigned. The undersigned makes the following representations and warranties, together with the representations made by the undersigned in the Purchaser Questionnaire attached hereto (which representations are incorporated herein by this reference), and undertakes to perform the following covenants, with the intent that they be relied upon by the Company and its counsel, officers, directors, employees and agents in determining the undersigned's suitability as a purchaser of the Units. The undersigned hereby agrees that such representations, warranties and covenants shall survive his/her purchase of the Units. By signing this Agreement, the undersigned represents that he/she has read and acknowledged the representations set forth in this Section 3. If more than one person is signing this Agreement, each representation, each warranty and each covenant made herein shall be a joint and several representation, warranty or covenant of each person.

(a) The undersigned is the sole and true party in interest, is acquiring the Units for his/her own account for investment, is not purchasing the Units subscribed for hereby for the benefit of any other person, and has no present intention of holding or managing the Units with others or of selling, distributing or otherwise disposing of any portion of the Units.

(b) The undersigned (i) is a citizen of the United States, (ii) is, if a natural person, at least 21 years of age and (iii) is a bona fide permanent resident of and is domiciled in the state set forth on the signature page hereof and has no present intention of becoming a resident of any other state or jurisdiction.

(c) The undersigned is aware that an investment in the Units is highly speculative and subject to substantial risks. The undersigned has adequate means of providing for his/her current needs and possible contingencies, and is able to bear the high degree of economic risk of this investment, including, but not limited to, the possibility of the complete loss of the undersigned's entire investment and the limited transferability of the Units, which may make the liquidation of this investment impossible for the indefinite future.

(d) The undersigned has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Units and making an informed investment decision.

(e) The undersigned understands that none of the Units, the Debentures, the Conversion Shares, the Warrants or the Warrant Shares (collectively, the "Securities") will be registered in this Offering under the Securities Act of 1933, as amended (the "1933 Act"), or any state securities laws, in partial reliance upon exemptions from registration for certain private offerings. The undersigned understands and agrees that the Securities, or any interest therein, may not be resold or otherwise disposed of by the undersigned unless such Securities are subsequently registered under the 1933 Act and under all applicable state securities laws or unless the Company receives an opinion of counsel satisfactory to it that an exemption from registration is available (as more particularly provided in the form of Debenture and form of Warrant attached to the Memorandum).

(f) The undersigned understands that only the Company can take action so as to register the Securities. Nonetheless, the undersigned will have certain limited registration rights to the extent such rights are expressly provided by a registration rights agreement (the "Registration Rights Agreement") executed in connection with this Agreement by the undersigned and the Company. Such registration rights consist of certain incidental rights to obligate the Company to register Conversion Shares or Warrant Shares upon request of the holder thereof if the Company

otherwise registers securities of the Company, as more particularly set forth in the Registration Rights Agreement.

(g) The undersigned acknowledges and represents that he/she has received and reviewed a copy of the Memorandum and any amendments or supplements thereto, has been given a reasonable opportunity to review all documents, books and records of the Company pertaining to this investment, has been supplied with all additional information concerning the Company and the Units that has been requested by the undersigned, has had a reasonable opportunity to ask questions of and receive answers from the Company or its representatives concerning this investment, and that all such questions have been answered to the full satisfaction of the undersigned.

(h) The undersigned has received no representations, written or oral, from the Company or its officers, directors, employees, attorneys or agents, other than those contained in the Memorandum or this Agreement. In making his/her decision to purchase the Units, the undersigned has relied solely upon his/her review of the Memorandum, this Agreement, and independent investigations made by him/her or his/her representatives without assistance of the Company or any of its officers, directors, employees or agents. Furthermore, in making such decision, the undersigned has not relied on (i) any research reports or other information prepared by members of the financial or investment community or (ii) any materials other than the Memorandum and this Agreement.

(i) The undersigned understands and agrees that the following restrictions and limitations are applicable to his/her purchases and resales, pledges, hypothecations or other transfers of the Securities:

(i) The Securities shall not be sold, pledged, hypothecated or otherwise transferred unless registered under the 1933 Act and applicable state securities laws or an exemption from such registration is available;

(ii) In addition to any other legend specified in the Memorandum, or the form of Debenture, the form of Warrant or the form of Registration Rights Agreement attached thereto, as applicable, each certificate or other document evidencing or representing Securities shall be stamped or otherwise imprinted with a legend in substantially the following form (any conflict among such forms of legend to be resolved by the Company in its sole discretion):

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON EXEMPTIONS FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED, AND VARIOUS APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR ASSIGNED OR A SECURITY INTEREST CREATED THEREIN, UNLESS THE PURCHASER, TRANSFEREE, ASSIGNEE, PLEDGEE OR HOLDER OF SUCH SECURITY INTEREST COMPLIES WITH ALL STATE AND FEDERAL SECURITIES LAWS (I.E., SUCH UNITS ARE REGISTERED UNDER SUCH LAWS OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE THEREUNDER) AND UNLESS THE SELLER, TRANSFEROR, ASSIGNOR, PLEDGOR OR GRANTOR OF SUCH SECURITY INTEREST PROVIDES AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT THE TRANSACTION CONTEMPLATED WOULD NOT BE IN VIOLATION OF THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS. TRANSFERABILITY OF THE SECURITIES IS THEREFORE

LIMITED AND INVESTORS MUST BEAR THE ECONOMIC RISK OF THEIR INVESTMENT FOR AN INDEFINITE PERIOD OF TIME.

(j) The undersigned acknowledges and represents that he/she has completed and executed the Purchaser Questionnaire attached hereto and that the information contained in such questionnaire is complete and accurate.

(i) the percentage of profit and/or amount of or type of consideration, profit or loss to be realized, if any, as a result of an investment in the Units; or

(ii) the possibility that the past performance or experience on the part of any subsidiary, officer, director, employee, agent or affiliate of the Company might in any way indicate or predict the results of ownership of the Units or the potential success of the Company's operations.

(n) The undersigned represents that he/she has read and considered fully the sections in the Memorandum entitled "INVESTOR SUITABILITY STANDARDS" and "RISK FACTORS AND INVESTMENT CONSIDERATIONS" and understands that (i) any investment in the Units is speculative and is subject to a high degree of risk and (ii) there are substantial restrictions on the transferability of the Securities which may make impossible or impractical the liquidation of an investment in the Units in case of an emergency.

(o) The undersigned (i) acknowledges that the Memorandum, the information contained therein, and all other information concerning the Company delivered to the undersigned in connection with the Offering (collectively, the "Proprietary Information") constitutes proprietary confidential information of the Company, (ii) warrants to the Company that he/she shall not use, disclose or disseminate the Proprietary Information except for the sole and isolated purpose of making an investment decision related to the purchase of the Units, and (iii) represents and warrants that he/she has not distributed or disseminated, nor will he/she at any time distribute or disseminate, the Proprietary Information to anyone other than personal advisors of the
