DATED:

THIS
IS TO CERTIFY that, for value received, Remsen Funding Corporation of New York or its registered assigns (herein collectively referred to as the "Warrantholder"), is entitled to the number of
Warrants (the "Warrants") set forth above, each of which represents the right, upon the due exercise hereof, at any time commencing on the date hereof (the "Commencement Date") (subject to the vesting
schedule set forth in Section 3 and accelerated vesting as provided in Section 4 hereof) and ending on the 42nd month after the Commencement Date (the "Expiration Date"), to purchase
from Sento Corporation, a Utah corporation (the "Company"), one share of common stock, par value $.25 per share (the "Common Stock"), of the Company upon surrender hereof, with the form of election to
purchase included herein (the "Election to Purchase") completed and duly executed, at the office of the Company, and upon simultaneous payment therefor of an exercise price per share equal to the
Purchase Price (as defined in Section 1 below) in cash and/or check payable to the order of the Company or by "cashless exercise" (as set forth in Section 6 hereof). The number of shares
of Common Stock issuable upon exercise of the Warrants (individually, a "Share" and collectively, the "Shares") and the Purchase Price therefor are subject to adjustment as provided herein. 

        1.    Purchase Price    

        The
purchase price for the Shares purchasable hereunder (the "Purchase Price") shall be equal to $3.00 per Share, subject to adjustment as hereinafter described. 

        2.    Definition of Market Price    

        Unless
otherwise provided herein, for purposes of any computations made hereunder, "Market Price" per share of Common Stock on any date shall be: (i) if the Common Stock is listed
or admitted for trading on any national securities exchange, the last reported sales price as reported on such national securities exchange; (ii) if the Common Stock is not listed or admitted
for trading on any national securities exchange, the average of the last reported closing bid and asked quotation for the Common Stock as reported on the Nasdaq Stock Market's National Market ("NNM")
or Nasdaq Stock Market's Small Cap Market ("NSM")or a similar service if NNM or NSM are not reporting such information; (iii) if the Common Stock is not listed or admitted for trading on any
national securities exchange, NNM or NSM or a similar service, the average of the last reported bid and asked quotation for the Common Stock as quoted by a market maker in the Common Stock (or if
there is more than one market maker, the bid and asked quotation shall be obtained from two market makers and the 

1

 

average
of the lowest bid and highest asked quotation shall be the "Market Price"); or (iv) if the Common Stock is not listed or admitted for trading on any national securities exchange or NNM
or quoted by NSM and there is no market maker in the Common Stock, the fair market value of such shares as determined in good faith by the Board of Directors of the Company. 

        3.    Vesting Schedule    

        The
Warrants shall vest in equal quarterly amounts of 1,250 shares (as adjusted for any changes in the Company's outstanding shares of Common Stock by reason of a stock dividend, stock
split, combination of shares, recapitalization, merger, consolidation, transfer of assets, reorganization, conversion or what the Board of Directors deems to be similar circumstances) on the first day
of each 3 month period following the Commencement Date. In the event of a "change of control" (as defined in Section 4 hereof) of the Company occurs at anytime prior to one year from the
date hereof, the vesting scheduled set forth above shall be accelerated and the Warrants shall be exercisable for up to 100% of the total number of shares subject to the Warrants (as adjusted for any
changes in the Company's outstanding shares of Common Stock by reason of a stock dividend, stock split, combination of shares, recapitalization, merger, consolidation, transfer of assets,
reorganization, conversion or what the Board of Directors of the Company deems to be similar circumstances). 

        4.    Change of Control    

        In
the event a Change of Control (as defined below) occurs at any time prior to the one year anniversary of the Commencement Date, then the Warrants shall become immediately exercisable
as provided in Section 3 above. A "Change of Control" shall be deemed to have occurred upon the happening of any of the following events:(i) the shareholders of the Company approve a
merger or consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto
continuing to represent more than fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger
or consolidation, or the shareholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the
Company's assets (other than to a subsidiary or subsidiaries) or (ii) any other event deemed to constitute a "Change of Control" by the Board of Directors of the Company. 

        5.    Transfer    

        The
Warrants may be freely transferred, sold or assigned by Warrantholder. 

        6.    Issuance of Shares; Cashless Exercise    

        Subject
to the restrictions set forth in Section 7 below, upon surrender of the Warrants and payment of the Purchase Price as aforesaid, the Company shall issue and deliver with
all reasonable dispatch the certificate(s) for the Shares to or upon the written order of the Warrantholder and in such name or names as the Warrantholder may designate. Such certificate(s) shall
represent the number of Shares
issuable upon the exercise of the Warrants, together with a cash amount in respect of any fraction of a Share otherwise issuable upon such exercise. 

        In
lieu of paying the Purchase Price in cash and/or upon exercise of the Warrants, the Warrantholder may elect a "cashless exercise" in which event the Warrantholder will receive upon
exercise a reduced number of Shares equal to (i) the number of Shares that would be issuable pursuant to the Warrants upon payment of the Purchase Price minus (ii) the number of Shares
that have an aggregate Market Price equal to the Purchase Price. 

        Certificates
representing the Shares shall be deemed to have been issued and the person so designated to be named therein shall be deemed to have become a holder of record of such Shares
as of the date of the surrender of the Warrants and payment of the Purchase Price as aforesaid; 

2

 

notwithstanding
that the transfer books for the Shares or other classes of stock purchasable upon the exercise of the Warrants shall then be closed or the certificate(s) for the Shares in respect of
which the Warrants is then exercised shall not then have been actually delivered to the Warrantholder. As soon as practicable after each such exercise of the Warrants, the Company shall issue and
deliver the certificate(s) for the Shares issuable upon such exercise, registered as requested. The Warrants shall be exercisable, at the election of the registered holder hereof, either as an
entirety or from time to time for part of the number of Shares specified herein, but in no event shall fractional Shares be issued with regard to the exercise of the Warrants. In the event that only a
portion of the Warrants is exercised at any time prior to the close of business on the Expiration Date, a new warrant certificate shall be issued to the Warrantholder for the remaining number of
Shares purchasable pursuant hereto. The Company shall cancel the Warrants when they are surrendered upon exercise. 

        Prior
to due presentment for registration of transfer of the Warrants, the Company shall deem and treat the Warrantholder as the absolute owner of the Warrants (notwithstanding any
notation of ownership or other writing on this warrant certificate made by anyone other than the Company) for the purpose of any exercise hereof or any distribution to the Warrantholder and for all
other purposes, and the Company shall not be affected by any notice to the contrary. 

        7.    Payment of Expenses, Taxes, etc. upon Exercise    

        The
Company shall pay all documentary stamp taxes, if any, attributable to the initial issuance of the Shares issuable upon the exercise of the Warrants; provided, however, that the
Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issue or delivery of any certificates for Shares in a name other than that of the
Warrantholder upon the exercise of the Warrants, and in such case the Company shall not be required to issue or deliver any certificates for Shares until or unless the person or persons requesting the
issuance have paid to the
Company the amount of such tax or have established to the Company's satisfaction that such tax has been paid or is not required to be paid. 

        8.    Lost, Stolen, or Mutilated Warrant Certificate    

        In
case this warrant certificate shall be mutilated, lost, stolen or destroyed, the Company shall issue and deliver, in exchange and substitution for and upon cancellation of the
mutilated warrant certificate, or in lieu of and substitution for the warrant certificate lost, stolen or destroyed, a new warrant certificate of like tenor and representing an equivalent number of
Shares purchasable upon exercise, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of such warrant certificate and reasonable indemnity, if
requested, also reasonably satisfactory to the Company. No bond or other security shall be required from the original Warrantholder in connection with the replacement by the Company of a lost, stolen
or mutilated warrant certificate. 

        9.    Covenants of Company    

        (a)   The
Company shall at all times through the Expiration Date reserve and keep available, out of its aggregate authorized but unissued shares of Common Stock, the number of
Shares deliverable upon the exercise of the Warrants. 

        (b)   Before
taking any action which would cause an adjustment pursuant to the terms set forth herein reducing the portion of the Purchase Price attributable to the Shares
below the then par value (if any) of such Shares, the Company shall take any corporate action which may, in the opinion of its counsel (which may be counsel regularly engaged by the Company), be
necessary in order that the Company may validly and legally issue fully paid and nonassessable Shares at the Purchase Price as so adjusted. 

3

 

        (c)   The
Company covenants that all Shares issued upon exercise of the Warrants shall, upon issuance in accordance with the terms hereof, be fully paid and nonassessable and
free from all pre-emptive rights and taxes, liens, charges and security interests created by the Company with respect to the issuance and holding thereof. 

        (d)   For
so long as the Warrants are outstanding, the Company shall notify the Warrantholder not less than 30 days prior to any cash dividend being paid to the holders
of Common Stock. 

        10.    Rights Upon Expiration    

        Unless
the Warrants are surrendered and payment made for the Shares as herein provided before the close of business on the Expiration Date, this warrant certificate will become wholly
void and all rights evidenced hereby will terminate after such time. 

        11.    Exchange of Warrant Certificate    

        Subject
to the provisions of Section 6 above, this warrant certificate may be exchanged for a number of warrant certificates of the same tenor as this warrant certificate for the
purchase in the aggregate of the same number of Shares of the Company as are purchasable upon the exercise of this warrant certificate, upon surrender hereof at the office of the Company with written
instructions as to the denominations of the warrant certificates to be issued in exchange. 

        12.    Adjustment for Certain Events    

        (a)   In
case the Company shall at any time after the date the Warrants are first issued (i) declare a dividend on the Common Stock payable in shares of the Company's
capital stock (whether in shares of Common Stock or of capital stock of any other class), (ii) subdivide the outstanding Common Stock, (iii) reverse split the outstanding Common Stock
into a smaller number of shares, or (iv) issue any shares of the Company's capital stock in a reclassification of the Common Stock (including any such reclassification in connection with a
consolidation or merger in which the Company is the continuing corporation), then, in each case, the Purchase Price in effect at the time of the record date for such dividend or of the effective date
of such subdivision, reverse split or reclassification, and/or the number and kind of shares of capital stock issuable upon exercise of the Warrants on such date, shall be proportionately adjusted so
that the holder of any Warrant exercised after such time shall be entitled to receive the aggregate number and kind of securities which, if such Warrant had been exercised immediately prior to such
date, such holder would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, reverse split or reclassification. Such adjustment shall be made
successively whenever any event listed above shall occur. 

        (b)   In
case the Company shall fix a record date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a
consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness or assets (other than cash dividends or cash distributions payable out of earnings,
consolidated earnings, if the Company shall have one or more subsidiaries, or earned surplus, or dividends payable in Common Stock) or rights, options or warrants to subscribe for or purchase Common
Stock, then, in each case, the Purchase Price per Share to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by
a fraction, of which the numerator shall be the current Market Price for a share of Common Stock on such record date less the fair market value of the portion of the assets or evidences of
indebtedness so to be distributed or of such subscription rights, options or warrants applicable to one share of Common Stock, and of which the denominator shall be the current Market Price for a
share of Common Stock. In the event that the Company and the Warrantholder cannot agree as to such fair market value, such determination of fair market value shall be made by an appraiser who shall be
mutually selected by the Company and the Warrantholder, and the reasonable costs 

4

 

of
such appraiser shall be borne by the Company. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such distribution is not so made, the Purchase
Price shall again be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed. 

        (c)   No
adjustment in the Purchase Price shall be required unless such adjustment would require a decrease of at least one cent ($0.01) in such price; provided, however, that
any adjustment which by reason of this Section 12(c) is not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this
Section 12 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be, but in no event shall the Company be obligated to issue fractional
shares of Common Stock or fractional portions of any securities upon the exercise of the Warrants. 

        (d)   In
the event that at any time, as a result of an adjustment made pursuant to Section 12 hereof, the holder of any Warrant thereafter exercised shall become
entitled to receive any shares of capital stock or warrants or other securities of the Company other than the Shares, thereafter the number of such other shares of capital stock or warrants or other
securities so receivable upon exercise of this Warrant shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to
the Shares contained in this Section 12, and the provisions of this warrant certificate with respect to the Shares shall apply, to the extent applicable, on like terms to any such other shares
of capital stock or warrants or other securities. 

        (e)   Upon
each adjustment of the Purchase Price as a result of calculations made in this Section 12, each Warrant outstanding immediately prior to the making of such
adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of Shares (calculated to the nearest hundredth), obtained by (i) multiplying the number
of Shares purchasable upon exercise of a Warrant immediately prior to such adjustment of the Purchase Price by the Purchase Price in effect immediately
prior to such adjustment and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price. 

        (f)    In
case of any capital reorganization of the Company or of any reclassification of the Common Stock (other than a change in par value or from a specified par value to no
par value or from no par value to a specified par value or as a result of subdivision or combination) or in case of the consolidation of the Company with, or the merger of the Company into, any other
corporation (other than a consolidation or merger in which the Company is the continuing corporation) or of the sale of the properties and assets of the Company as, or substantially as, an entirety,
each Warrant shall, after such reorganization, reclassification, consolidation, merger or sale, be exercisable, upon the terms and conditions specified herein, for the number of shares of Common Stock
or other capital stock or warrants or other securities or property to which a holder of the number of shares of Common Stock purchasable (at the time of such reorganization, reclassification,
consolidation, merger or sale) upon exercise of such Warrant would have been entitled upon such reorganization, reclassification, consolidation, merger or sale; and in any such case, if necessary, the
provisions set forth in this Section 12(f) with respect to the rights and interests thereafter of the registered holders of all Warrants shall be appropriately adjusted so as to be applicable,
as nearly as may reasonably be, to any shares of Common Stock or other capital stock or warrants or other securities or property thereafter deliverable on the exercise of the Warrants. The
subdivision, reverse split or combination of shares of Common Stock at any time outstanding into a greater or lesser number of shares shall not be deemed to be a reclassification of the Common Stock
for the purposes of this Section 12(f). 

5

 

        (g)   In
any case in which this Section 12 shall require that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the
Company may elect to defer until the occurrence of such event issuing to the Warrantholder, if such Warrantholder exercised any Warrant after such record date, shares of capital stock or warrant or
other securities of the Company, if any, issuable upon such exercise over and above the Shares issuable, on the basis of the Purchase Price in effect prior to such adjustment; provided, however, that
the Company shall deliver to the holder a due bill or other appropriate instrument evidencing such holder's right to receive such shares of capital stock or warrants or other securities upon the
occurrence of the event requiring such adjustment. 

        13.    Fractional Shares    

        Upon
exercise of the Warrants the Company shall not be required to issue fractional shares of Common Stock or other capital stock. In lieu of such fractional shares, the Warrantholder
shall receive an amount in cash equal to the same fraction of the (i) current Market Price of one whole Share if clause (i), (ii) or (iii) in the definition of Market Price
in Section 2 above is applicable or (ii) book value of one whole Share as reported in the Company's most recent audited financial statements if clause (iv) in the definition of
Market Price in Section 2 above is applicable. All calculations under this Section 13 shall be made to the nearest cent. 

        14.    Registration Rights    

        The
Warrantholder shall be afforded piggyback registration rights with respect to the Shares. If the Company at any time or from time to time subsequent to the Commencement Date proposes
to register any securities under the Securities Act either for its own account or the account of any selling security holders (other than pursuant to (i) a registration statement on Forms
S-4 or S-8 or any successor or similar forms, (ii) a registration relating solely to a Rule 145 offering or (iii) a registration on any form that does not
permit secondary sales), it will give written notice to the Warrantholders of its intention at least twenty (20) days in advance of the filing of any registration statement with respect
thereto. Upon the written request of any of the Warrantholders given within fifteen (15) days after receipt of such notice, the Company will use its best efforts to include in such
registration, and in any underwriting involved therein, all the Shares included in such request. 

        15.    Securities Act Legend    

        The
Warrantholder shall not be entitled to any rights of a stockholder of the Company with respect to any Shares purchasable upon the exercise hereof, including voting, dividend or
dissolution rights, until such Shares have been paid for in full. As soon as practicable after such exercise, the Company shall deliver a certificate or certificates for the securities issuable upon
such exercise, all of which shall be fully paid and nonassessable, to the person or persons entitled to receive the same; provided, however, that, if applicable, such certificate or certificates
delivered to the holder of the surrendered Warrant shall bear a legend reading substantially as follows: 

        "These
securities have not been registered under the Securities Act of 1933, as amended, or the securities laws of any state and may not be sold or transferred in the absence of such
registration or any exemption therefrom under such Act and laws, if applicable. The Company, prior to permitting a transfer of these securities, may require an opinion of counsel or other assurances
satisfactory to it as to compliance with or exemption from such Act and laws." 

        16.    Notice of Adjustment    

        (a)   Upon
any adjustment of the Purchase Price pursuant to Section 12 above, the Company, within 30 calendar days thereafter, shall have on file for inspection by the
Warrantholder a certificate of the Board of Directors of the Company setting forth the Purchase Price after such adjustment, the method of calculation thereof in reasonable detail, the facts upon
which such 

6

 

calculations
were based and the number of Shares issuable upon exercise of a Warrant after such adjustment in the Purchase Price, which certificate shall be conclusive evidence of the correctness of
the matters set forth therein. 

        (b)   In
case: 

          (i)  the
Company shall authorize the issuance to all holders of Common Stock of rights, options or warrants to subscribe for or purchase capital stock of the Company or of
any other subscription rights, options or warrants; or 

         (ii)  the
Company shall authorize the distribution to all holders of Common Stock of evidences of its indebtedness or assets; or 

        (iii)  of
any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, of the conveyance or transfer of
the properties and assets of the Company substantially as an entirety or of any capital reorganization or any reclassification of the Common Stock (other than a change in par value or from a specified
par value to no par value or from no par value to a specified par value or as a result of a subdivision or combination); or 

        (iv)  of
the voluntary or involuntary dissolution, liquidation or winding up of the Company; or 

         (v)  the
Company proposes to take any other action which would require an adjustment of the Purchase Price pursuant to Section 12 above; 

then,
in each such case, the Company shall give to the Warrantholder at its address appearing below at least 20 calendar days prior to the applicable record date hereinafter specified in (A), (B), or
(C) below, by first class mail, postage prepaid, a written notice stating (A) the date as of which the holders of record of shares of Common Stock entitled to receive any such rights,
options, warrants or distribution are to be determined or (B) the date on which any such consolidation, merger, conveyance, transfer, reorganization, reclassification, dissolution, liquidation
or winding up is expected to become effective, and the date as of which it is expected that holders of record of shares of Common Stock shall be
entitled to exchange such shares for securities or other property, if any, deliverable upon such consolidation, merger, conveyance, transfer, reorganization, reclassification, dissolution, liquidation
or winding up or (C) the date of such action which would require an adjustment of the Purchase Price. The failure to give the notice required by this Section 16(b) or any defect therein
shall not affect the legality or validity of any such issuance, distribution, consolidation, merger, conveyance, transfer, reorganization, reclassification, dissolution, liquidation, winding up or
other action or the vote upon any such action. 

        Except
as provided herein, nothing contained herein shall be construed as conferring upon the Warrantholder the right to vote on any matter submitted to the stockholders of the Company
for their vote or to receive notice of meetings of stockholders or the election of directors of the Company or any other proceedings of the Company, or any rights whatsoever as a stockholder of the
Company.

WARRANT TO PURCHASE 15,000 SHARES

OF COMMON STOCK OF

SENTO CORPORATION

(Void after December 1, 2004)  

Dated: November 10, 2003  

        This certifies that RCG Capital Markets Group, Inc. (the "Holder"), for value received, is entitled to purchase from Sento Corporation, a Utah corporation
(the "Company"), having a place of business at 808 East Utah Valley Drive, American Fork, UT 84003, a maximum of 15,000 fully paid and nonassessable shares of the Company's Common Stock ("Common
Stock") for cash at a price per share as set forth in Section 1 of this Warrant (the "Purchase Price") at any time or from time to time (subject to vesting provisions set forth in
Section 3 of this Warrant) up to and including 5:00 p.m. (Pacific time) on December 1, 2004, (the "Expiration Date"), upon surrender to the Company at its principal office (or at
such other location as the Company may advise the Holder in writing) of this Warrant properly endorsed with the Form of Subscription attached hereto duly filled in and signed and, if applicable, upon
payment in cash or by check of the aggregate Purchase Price for the number of shares for which this Warrant is being exercised determined in accordance with the provisions hereof. The Purchase Price
and the number of shares purchasable hereunder are subject to adjustment as provided in Section 5 of this Warrant. 

        This
Warrant is subject to the following terms and conditions: 

        1.    PURCHASE PRICE.    15,000 of the shares of Common Stock
underlying this Warrant have a Purchase Price of $8.48 per share. 

        2.    EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.    

        2.1    General.    This Warrant is exercisable at the option of the
holder of record hereof, at any time or from time to time from the date hereof until the Expiration Date for all or any part of the shares of Common Stock (but not for a fraction of a share) which may
be purchased hereunder. The Company agrees that the shares of Common Stock purchased under this Warrant shall be and are deemed to be issued to the Holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been surrendered, properly endorsed, the completed, executed Form of Subscription delivered and payment made for such shares.
Certificates for the shares of Common Stock so purchased, together with any other securities or property to which the Holder hereof is entitled upon such exercise, shall be delivered to the Holder
hereof by the Company at the Company's expense within a reasonable time after the rights represented by this Warrant have been so exercised. In case of a purchase of less than all the shares which may
be purchased under this Warrant, the Company shall cancel this Warrant and execute and deliver a new Warrant or Warrants of like tenor for the balance of the shares purchasable under the Warrant
surrendered upon such purchase to the Holder hereof within a reasonable time after the exercise of this Warrant as to such shares. Each stock certificate so delivered shall be in such denominations of
Common Stock as may be requested by the Holder hereof and shall be registered in the name of such Holder. 

        3.    VESTING.    Notwithstanding anything to the contrary in this
Warrant, this Warrant shall only be exercisable with respect to those shares of Common Stock that have vested as of the date of exercise. All such shares have been vested as of the date of the Warrant
document. 

 

        4.    SHARES TO BE FULLY PAID; RESERVATION OF SHARES.    The Company
covenants and agrees that all shares of Common Stock which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid
and nonassessable and free of all taxes, liens and charges with respect to the issue thereof. The Company further covenants and agrees that, during the period within which the rights represented by
this Warrant may be exercised, the Company will at all times have authorized and reserved, for the purpose of issue or transfer upon exercise of the rights evidenced by this Warrant, a sufficient
number of shares of authorized but unissued Common Stock, or other securities and property, when and as required to provide for the exercise of the rights represented by this Warrant. The Company will
take all such
action as may be necessary to assure that such shares of Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any domestic
securities exchange upon which the Common Stock may be listed; provided, however, that the Company shall not be required to effect a registration under Federal or State securities laws with respect to
such exercise, except as provided in Section 11 of this Warrant. The Company will not take any action which would result in any adjustment of the Purchase Price (as set forth in
Section 5 hereof) if the total number of shares of Common Stock issuable after such action upon exercise of all outstanding warrants, together with all shares of Common Stock then outstanding
and all shares of Common Stock then issuable upon exercise of all options and upon the conversion of all convertible securities then outstanding, would exceed the total number of shares of Common
Stock then authorized by the Company's Amended and Restated Articles of Incorporation. 

        5.    ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES.    The
Purchase Price and the number of shares purchasable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the occurrence of certain events described in this
Section 5. Upon each adjustment of the Purchase Price, the Holder of this Warrant shall thereafter be entitled to purchase, at the Purchase Price resulting from such adjustment, the number of
shares obtained by multiplying the Purchase Price in effect immediately prior to such adjustment by the number of shares purchasable pursuant hereto immediately prior to such adjustment, and dividing
the product thereof by the Purchase Price resulting from such adjustment. 

        5.1    Subdivision or Combination of Stock.    In case the Company
shall at any time subdivide its outstanding shares of Common Stock into a greater number of shares, the Purchase Price in effect immediately prior to such subdivision shall be proportionately reduced,
and conversely, in case the outstanding shares of Common Stock of the Company shall be combined into a smaller number of shares, the Purchase Price in effect immediately prior to such combination
shall be proportionately increased. 

        5.2    Dividends in Common Stock, Other Stock, Property,
Reclassification.    If at any time or from time to time the Holders of Common Stock (or any shares of stock or other securities at the time receivable upon the
exercise of this Warrant) shall have received or become entitled to receive, without payment therefor, 

        (a)   Common Stock or any shares of stock or other securities which are at any time directly or indirectly convertible into or
exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution, 

        (b)   any cash paid or payable otherwise than as a cash dividend, or 

        (c)   Common Stock or additional stock or other securities or property (including cash) by way of spinoff, splitup,
reclassification, combination of shares or similar corporate rearrangement, (other than shares of Common Stock issued as a stock split or adjustments in respect of which shall be covered by the terms
of Section 5.1 above), then and in each such case, the Holder shall, upon the exercise of this Warrant, be entitled to receive, in addition to 

2

 

the
number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the
cases referred to in clause (b) above and this clause (c)) which such Holder would hold on the date of such exercise had he been the holder of record of such Common Stock as of the date
on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property. 

        5.3    Reorganization, Reclassification, Consolidation, Merger or
Sale.    If any recapitalization, reclassification or reorganization of the capital stock of the Company, or any consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its assets or other transaction shall be effected in such a way that holders of Common Stock shall be entitled to receive stock, securities, or
other assets or property (an "Organic Change"), then, as a condition of such Organic Change, the Company shall, at its option, (i) pay to Holder the value of the Warrants (which shall be the
difference between the Purchase Price and the value of the consideration that would be received by Holder if the Warrant were exercised immediately prior to such Organic Change) and thereby retire the
Warrants; or (ii) make lawful and adequate provisions whereby the Holder shall thereafter have the right to purchase and receive (in lieu of the shares of the Common Stock of the Company
immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such warrants, shares of stock, securities or other assets or property as may be issued or
payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby; provided, however, that in the event the value of the stock, securities or other assets or property (determined in good faith by the Board of Directors of
the Company) issuable or payable with respect to one share of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby is
in excess of the Purchase Price effective at the time of a merger and securities received in such reorganization, if any, are publicly traded, then this Warrant shall expire unless exercised prior to
such Organic Change. In the event of any Organic Change, appropriate provision shall be made by the Company with respect to the rights and interests of the Holder to the end that the provisions of
this Warrant (including, without limitation, provisions for adjustments of the Purchase Price and of the number of shares purchasable and receivable upon the exercise of this Warrant and provisions
for a "net issue exercise" as set forth in Section 2.2 of this Warrant) shall thereafter be applicable, in relation to any shares of stock, securities or assets thereafter deliverable upon the
exercise hereof. 

        5.4    Notices of Change.    

        (a)   Immediately upon any adjustment in the number or class of shares subject to this Warrant and of the Purchase Price, the
Company shall give written notice of such adjustment to the Holder, setting forth in reasonable detail and certifying the calculation of such adjustment. 

        (b)   The Company shall give written notice to the Holder at least ten (10) business days prior to the date on which the
Company closes its books or takes a record for determining rights to receive any dividends or distributions. 

        (c)   The Company shall also give written notice to the Holder at least thirty (30) business days prior to the date on
which an Organic Change shall take place. 

        6.    ISSUE TAX.    The issuance of certificates for shares of Common
Stock upon the exercise of this Warrant shall be made without charge to the Holder for any issue tax in respect thereof; provided, however, that the Company shall not be required to pay (i) any
applicable income taxes that may be payable by the Holder with respect to this Warrant or (ii) any tax that may be payable in respect of any 

3

 

transfer
investing the issuance and delivery of any certificate in a name other than that of the then Holder of the Warrant being exercised. 

        7.    CLOSING OF BOOKS.    The Company will at no time close its
transfer books against the transfer of any warrant or of any shares of Common Stock issued or issuable upon the exercise of any warrant in any manner which interferes with the timely exercise of this
Warrant. 

        8.    NO VOTING OR DIVIDEND RIGHTS; LIMITATION OF
LIABILITY.    Nothing contained in this Warrant shall be construed as conferring upon the Holder the right to vote or to consent or to receive notice as a shareholder
of the Company or any other matters or any rights whatsoever as a shareholder of the Company. No dividends or interest shall be payable or accrued in respect of this Warrant or the interest
represented hereby or the shares purchasable hereunder until, and only to the extent that, this Warrant shall have been exercised. No provisions of this Warrant, in the absence of affirmative action
by the holder to purchase shares of Common Stock, and no mere enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the Purchase Price or as
a shareholder of the Company, whether such liability is asserted by the Company or by its creditors. 

        9.    REPRESENTATIONS OF HOLDER.    

        (a)   The Holder represents that it is an accredited investor within the meaning of Regulation D of the Securities Act
of 1933, as amended (the "Act"). 

        (b)   The Holder represents and warrants that it is acquiring the Warrant solely for its account for investment and not with a
view to or for sale or distribution of said Warrant or any part thereof. The Holder also represents that the entire legal and beneficial interests of the Warrant the Holder is acquiring is being
acquired for, and will be held for, its account only. The Holder also hereby represents and warrants that it has either (i) preexisting personal or business relationships with the Company or
any of its officers, directors or controlling persons, or (ii) the capacity to protect its own interests in connection with the grant of this Warrant by virtue of its business or financial
expertise or the business or financial expertise of any of the Holder's professional advisors who are unaffiliated with and who are not compensated by the Company or any of its Affiliates, directly or
indirectly. 

        (c)   The Holder understands that the Warrant and the shares of Common Stock issuable upon exercise of this Warrant have not
been registered under Act on the basis that no distribution or public offering of the stock of the Company is to be effected. The Holder realizes that the basis for the exemption may not be present
if, notwithstanding its representations, the Holder has a present intention of acquiring the securities for a fixed or determinable period in the future, selling (in connection with a distribution or
otherwise), granting any participation in, or otherwise distributing the securities. The Holder has no such present intention. 

        (d)   The Holder recognizes that this Warrant and the shares of Common Stock issuable upon exercise of this Warrant must be
held until they are subsequently registered under the Act or an exemption from such registration is available. 

        10.    WARRANTS TRANSFERABLE.    This Warrant and all rights hereunder
are non-transferable, in whole or in part, without the prior consent of the Company. 

        11.    REGISTRATION.    

        11.1    Piggyback Registrations.    The Company may, at its election,
notify the Holder in writing at least fifteen (15) days prior to the filing of any registration statement under the Securities Act for purposes of a public offering of securities of the Company
in order to afford the Holder an opportunity to include in such registration statement all of the Common Stock held by 

4

 

the
Holder. If the Holder desires to include in any such registration statement all or any part of the Common Stock held by it, it shall, within fifteen (15) days after the above-described
notice from the Company, so notify the Company in writing. The Company shall have the right (i) for marketing reasons or otherwise, to withdraw from the registration statement any shares of
Common Stock held by Holder that Holder has elected to include in such registration, and (ii) to terminate or withdraw any registration initiated by it under this Section 11.1 prior to
the effectiveness of such registration whether or not the Holder has elected to include securities in such registration. 

        11.2    Form S-3 Registration.    In case the
Company shall receive from the Holder a written request that the Company effect a registration on Form S-3 with respect to all of the Common Stock owned by the Holder, the Company
will, within thirty (30) days of receiving the request, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of the Holder's Common Stock as are specified in such request; provided, however, that the Company shall not be obligated to effect any such registration,
qualification or compliance pursuant to this Section 11.2 (i) if Form S-3 is not available for such offering by the Holder, (ii) if the Company shall furnish to
the Holder a certificate signed by the Chairman of the Board of Directors of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously
detrimental to the Company and its stockholders for such Form S-3 registration to be effected at such time, in which event the Company shall have the right to defer the filing of
the Form S-3 registration statement for a period of not more than one hundred twenty (120) days after receipt of the request of the Holder under this Section 11.2;
provided, that such right to delay a request shall be exercised by the Company not more than twice in any twelve (12) month period, (iii) in any particular jurisdiction in which the
Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance, (iv) if the Company has
previously effected a registration on Form S-3 for the Holder pursuant to this Section 11.2, or (v) all shares of Common Stock held by Holder may be sold pursuant to
Rule 144 during any ninety (90) day period. Subject to the foregoing, the Company shall file a Form S-3 registration statement covering the Common Stock and
other securities underlying this Warrant so requested to be registered as soon as practicable after receipt of the request of the Holder. 

        11.3    Expenses of Registration.    The Holder will pay 50% of
expenses relating to a registration on Form S-3, up to $5,000; otherwise, all expenses incurred in connection with any registration under this Section 11 shall be borne by
the Company. 

        12.    MODIFICATION AND WAIVER.    This Warrant and any provision
hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of the same is sought. 

        13.    NOTICES.    Any notice, request or other document required or
permitted to be given or delivered to the holder hereof or the Company shall be delivered or shall be sent by certified mail, postage prepaid, to each such holder at its address as shown on the books
of the Company or to the Company at the address indicated therefor in the first paragraph of this Warrant or such other address as either may from time to time provide to the other. 

        14.    BINDING EFFECT ON SUCCESSORS.    This Warrant shall be binding
upon any corporation succeeding the Company by merger, consolidation or acquisition of all or substantially all of the Company's assets. All of the obligations of the Company relating to the Common
Stock issuable upon the exercise of this Warrant shall survive the exercise and termination of this Warrant. All of the covenants and agreements of the Company shall inure to the benefit of the
successors and assigns of the holder hereof.

        15.    DESCRIPTIVE HEADINGS AND GOVERNING LAW.    The description
headings of the several sections and paragraphs of this Warrant are inserted for convenience only and do not constitute a part of this Warrant. This Warrant shall be construed and enforced in
accordance with, and the rights of the parties shall be governed by, the laws of the State of Utah. 

        16.    LOST WARRANTS.    The Company represents and warrants to the
Holder hereof that upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction, or mutilation of this Warrant (such as an affidavit of Holder) and, in the case of
any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to the Company, or in the case of any such mutilation upon surrender and cancellation of such Warrant, the
Company, at its expense, will make and deliver a new Warrant, of like tenor, in lieu of the lost, stolen, destroyed or mutilated Warrant. 

        17.    FRACTIONAL SHARES.    No fractional shares shall be issued upon
exercise of this Warrant. The Company shall, in lieu of issuing any FRACTIONAL share, pay the holder entitled to such fraction a sum in cash equal to
such fraction multiplied by the then effective Purchase Price.

Attn:
President 

Ladies
and Gentlemen: 

        The
undersigned,                        ("Purchaser"), intends to acquire up
to                        shares of the Common Stock (the "Common Stock") of Sento Corporation (the "Company") from the
Company pursuant to the exercise or conversion of a Warrant to purchase Common Stock held by Purchaser. The Common Stock will be issued to Purchaser in a transaction not involving a public offering
and pursuant to an exemption from registration under the Securities Act of 1933, as amended (the "1933 Act") and applicable state securities laws. In connection with such purchase and in order to
comply with the exemptions from registration relied upon by the Company, Purchaser represents, warrants and agrees as follows: 

        Purchaser
is acquiring the Common Stock for its own account, to hold for investment and not with a view to, or for resale in connection with, the distribution thereof and has no present
intention of distributing or reselling such shares and Purchaser shall not make any sale, transfer or other disposition of the Common Stock in violation of the 1933 Act or the General Rules and
Regulations promulgated thereunder by the Securities and Exchange Commission (the "SEC") or in violation of any applicable state securities law. 

        Purchaser
has either (i) preexisting personal or business relationships with the Company or any of its officers, directors or controlling persons, or (ii) the capacity to
protect its own interests in connection with the acquisition of Common Stock by virtue of its business or financial expertise or the business or financial expertise of any of Purchaser's professional
advisors who are unaffiliated with and who are not compensated by the Company or any of its Affiliates, directly or indirectly. 

        Purchaser
is an accredited investor within the meaning of Regulation D of the 1933 Act. Purchaser is
experienced in making investments of this type and has such knowledge and background in financial and business matters that it is capable of evaluating the merits and risks of this investment and
protecting its own interests. 

        Purchaser
has been advised that the Common Stock has not been registered under the 1933 Act or state securities laws on the ground that this transaction is exempt from registration, and
that reliance by the Company on such exemptions is predicated in part on Purchaser's representations set forth in this letter. 

        Purchaser
has been informed that under the 1933 Act, the Common Stock must be held indefinitely unless it is subsequently registered under the 1933 Act or unless an exemption from such
registration (such as Rule 144) is available with respect to any proposed transfer or disposition by Purchaser of the Common Stock. Purchaser further agrees that the Company may refuse to
permit Purchaser to sell, transfer or dispose of the Common Stock (except as permitted under Rule 144) 

1

 

unless
there is in effect a registration statement under the 1933 Act and any applicable state securities laws covering such transfer, or unless Purchaser furnishes an opinion of counsel reasonably
satisfactory to counsel for the Company, to the effect that such registration is not required. 

        Purchaser
also understands and agrees that (unless such Common Stock (i) shall no longer be "restricted securities" as defined in Rule 144 under the 1933 Act or any
successor provision thereof, (ii) may be sold pursuant to Rule 144(k) under the 1933 Act or any successor provision thereof, or (iii) has been sold in a transaction under the 1933
Act or any successor provision thereof) there will be placed on the certificate(s) for the Common Stock, or any substitutions therefor, a legend stating in substance: 

        "The
shares represented by this certificate have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws. These shares have
been acquired for investment and may not be sold or otherwise transferred in the absence of an effective registration statement for these shares under the Securities Act and applicable state
securities laws, or an opinion of counsel satisfactory to the Company that registration is not required and that an applicable exemption is available." 

        Purchaser
has carefully read this letter and has discussed its requirements and other applicable limitations upon Purchaser's resale of the Common Stock with Purchaser's counsel. 

	

 	

Very truly yours,
