(g)     

	
Investment Intent.   Employee represents that all common shares of SCV or other securities of SCV purchased by Employee
pursuant to the exercise of all or any portion of the Options will be acquired only for investment and not with a view to distribution, and that he will not sell or otherwise dispose of any such common shares or other securities of SCV in any manner which is contrary
to the laws, regulations and rules enforced or promulgated by the Securities and Exchange Commission of the United States. SCV agrees that if it shall register any shares of SCV presently issued and outstanding for distribution and sale to the public in accordance
with the laws, regulations and rules enforced or promulgated by the Securities and Exchange Commission of the United States, it will include in such registration such proportion of the SCV shares previously acquired by Employee in the same ratio to the total number
of shares acquired by Employee pursuant to the Options as the number of shares of SCV common stock owned by other shareholders included in such registration bears to the total number of SCV shares then issued and outstanding owned by such other
shareholders.

	
          

		
		
(h)     

	
Accelerated Vesting Upon Sale of SCV.  In the event a majority ownership interest in SCV greater than fifty percent (50%) is sold to a third party (“Majority
Sale”) at any time prior to the vesting of the Options, the Options shall immediately vest upon the consummation of the Majority Sale.

                                RIGHTS AGREEMENT

         THIS RIGHTS AGREEMENT (this "Agreement"), dated as of the 3rd day of
June, 2005, is entered into by and between SENTO CORPORATION, a Utah corporation
(the "Company"), and AMERICAN STOCK TRANSFER & TRUST COMPANY (the "Rights
Agent").

         WHEREAS, in order to preserve stockholder value, the Company's Board of
Directors has determined that it is advisable for the Company to adopt a
stockholder rights plan (the "Rights Plan") to protect the Company and its
stockholders from abusive acquisition tactics;

         WHEREAS, in order to implement the Rights Plan, the Company's Board of
Directors has authorized and declared a dividend distribution of one right
("Right") effective 5:00 p.m. (Mountain time) on June 3, 2005 (the "Record
Date") for each Common Share (as hereinafter defined) outstanding at the Close
of Business (as hereinafter defined) on the Record Date; and has authorized the
issuance of one Right in respect of each Common Share issued after the Record
Date and until the earliest to occur of the Separation Date, the Expiration
Date, or the Redemption Date (as such terms are hereinafter defined);

         WHEREAS, each Right entitles the holder thereof, after the Separation
Date, to purchase securities of the Company (or in certain cases, of certain
other entities) pursuant to the terms and subject to the conditions set forth
herein; and

         WHEREAS, the Company desires to appoint the Rights Agent to act on the
Company's behalf, and the Rights Agent is willing to so act, in connection with
the issuance, transfer, exchange, and replacement of Rights Certificates (as
hereinafter defined), the exercise of Rights, and other matters referred to
herein.

         NOW, THEREFORE, in consideration of the premises and respective
agreements set forth herein, the parties hereby agree as follows:

                                    ARTICLE I
                               CERTAIN DEFINITIONS

         1.1 Certain Definitions.

         For purposes of this Agreement, the following terms have the following
meanings:

                  (a) "Acquiring Person" shall mean any Person that, together
         with all Affiliates and Associates of such Person, will be the
         Beneficial Owner of twenty percent (20%) or more of the Voting Shares
         of the Company then outstanding, but shall not include the Company, any
         Company Subsidiary, any employee benefit plan of the Company or any
         Company Subsidiary, or any Person or entity organized, appointed, or
         established by the Company or such Company Subsidiary for or pursuant
         to the terms of any such employee benefit plan. Notwithstanding the
         foregoing, no Person shall become an Acquiring Person solely as the
         result of a reduction in the number of Voting Shares outstanding due to
         an acquisition of Voting Shares by the Company that increases the
         proportionate number of such Voting Shares Beneficially Owned by such
         Person to twenty percent (20%) or more unless and until that Person
         shall purchase or otherwise become (as a result of actions by such
         Person or its Affiliates or Associates) the Beneficial Owner of any
         additional Voting Shares of the Company.

                  (b) "Affiliate" of, or a Person "affiliated" with, a specified
         Person shall mean a Person that directly, or indirectly through one or
         more intermediaries, controls, is controlled by, or is under common
         control with such specified Person.

                  (c) "Associate" used to indicate a relationship with a
         specified Person, shall mean:

                  or any Person with whom such specified Person is living in a
                  conjugal relationship outside marriage, or any relative of
                  such spouse or other Person who has the same home as such
                  specified Person or a director or officer of the Company or an
                  Affiliate of the Company;

                           (iv) any Person who is a director, officer, member,
                  partner, or trustee of such specified Person or of any
                  corporation, partnership, or other organization (other than
                  the Company or any wholly-owned Company Subsidiary) that is an
                  Affiliate or Associate of such specified Person; and

                           (v) any corporation of which such specified Person
                  beneficially owns, directly or indirectly, voting securities
                  carrying more than ten percent (10%) of the rights attaching
                  to all voting securities of such corporation for the time

                  Exchange Act (or pursuant to any comparable or successor laws
                  or regulations or, if such rules shall be rescinded and there

                  this Agreement); and

                           (ii) as to which such Person or any of such Person's
                  Affiliates or Associates has the right to become Beneficial
                  Owner (whether such right is exercisable immediately or only
                  after the passage of time or the occurrence of changes in
                  Market Prices) pursuant to any contract, agreement,
                  arrangement, or understanding, or upon the exercise of any
                  rights (other than the Rights), whether conversion rights,
                  exchange rights, warrants, options, or otherwise;

         provided, however, that a Person shall not be deemed the "Beneficial
         Owner," to have "Beneficial Ownership" of, or to "Beneficially Own" any
         security:

                           (x) tendered pursuant to a tender or exchange offer

                  security being accepted for payment or exchange or being taken
                  up and paid for; or

                           (xi) as to which such Person's Affiliates or
                  Associates have or share the voting power or have the power to
                  direct the voting pursuant to a revocable proxy given in
                  response to a public proxy solicitation made pursuant to, and
                  in accordance with, the applicable rules and regulations under
                  the Exchange Act, except if such power (or the arrangement
                  relating thereto) is then reportable under Item 6 of Schedule
                  13D under the Exchange Act (or any similar provision of a
                  comparable or successor report).

                           percentage); or

                           otherwise acting jointly or in concert.

                  (o) "Market Price" of any securities (including the Rights) on
         any date of determination shall mean the average of the daily closing

         below) on each of the 20 consecutive Trading Days through and including

         that if an event of a type analogous to any of the events described in
         Section 2.3 hereof shall have caused the closing prices used to
         determine the Market Price on any Trading Day not to be fully
         comparable with the closing price on such date of determination, each
         such closing price so used shall be appropriately adjusted in a manner
         analogous to the applicable adjustment provided for in Section 2.3
         hereof in order to make it fully comparable with the closing price on
         such date of determination. The closing price per share of any

         not listed or admitted to trading on any national securities exchange,
         the closing board lot sale price, (iii) if for any reason none of such

         such other system then in use, or (iv) if on any such date the
         securities are not quoted by any such organization, the average of the
         closing bid and asked prices as furnished by a professional market
         maker making a market in the securities selected in good faith by the
         Board of Directors of the Company; provided, however, that if on any
         such date the securities are not traded in the over-the-counter market,
         the closing price per share of such securities on such date shall mean
         the fair value per share of securities on such date as determined in
         good faith by the Board of Directors of the Company after consultation
         with a nationally recognized investment banking firm with respect to
         the fair value per share of such securities.

         Company, and (ii) within said 12-month period have not disclosed, or
         caused the disclosure of, any intention that would result in the
         acquisition or influence of control of the Company (any such Persons
         meeting the conditions specified in clauses (i) and (ii), an
         "Offeror"), and which proposal:

                                    (1) provides for acquisition of all of the
                           outstanding Voting Shares held by any Person other
                           than the Offeror and its Affiliates for cash at the
                           same specified price;

                           than the Offeror and its Affiliates and is at a price
                           that is not less than the book value;

                                    (3) states that such offer shall remain open
                           for at least 90 days and shall include all Voting
                           Shares outstanding as of the date of the proposal or

                           the date of the proposal and that the Offeror has
                           obtained written financing commitments from

Directors for purposes of applying the definitions contained in this Article 1
shall be made by the Board of Directors in its good faith judgment, which
determination shall be conclusive and binding on the Rights Agent and the

                                   ARTICLE II
                                   THE RIGHTS

         2.1 Legend on Common Share Certificates.

         Certificates for the Common Shares issued after the Record Date, but
prior to the Close of Business on the Separation Date, shall evidence one Right
for each Common Share represented thereby and shall have impressed on, printed
on, written on, or otherwise affixed to them, the following legend:

         Until the Separation Date (as defined in the Rights Agreement referred
         to below), this certificate also evidences and entitles the holder
         thereof to certain Rights as set forth in a Rights Agreement, dated
         June 3, 2005 (the "Rights Agreement"), between Sento Corporation (the
         "Company") and American Stock Transfer & Trust Company, as Rights
         Agent, the terms of which are hereby incorporated by reference and a
         copy of which is on file at the principal executive office of the
         Company. Under certain circumstances, as set forth in the Rights
         Agreement, such Rights may be redeemed by the Company, may expire, may
         become void (if, in certain cases, they are "Beneficially Owned" by an
         "Acquiring Person," as such terms are defined in the Rights Agreement,
         or a transferee thereof), or may be evidenced by separate certificates
         and may no longer be evidenced by this certificate. The Company will
         mail or arrange for the mailing of a copy of the Rights Agreement to
         the holder of this certificate without charge within five days after
         the receipt of a written request therefor.

Certificates representing Common Shares of the Company that are issued and
outstanding at the Record Date shall evidence one Right for each Common Share
evidenced thereby notwithstanding the absence of the foregoing legend.

         2.2 Initial Exercise Price; Exercise of Rights; Detachment of Rights.

                  (a) Subject to adjustment as herein set forth, each Right will
         entitle the holder thereof, after the Separation Date, to purchase,
         subject to adjustment from time to time as provided herein, 1/100 of a
         Preferred Share at the Exercise Price.

                  (b) Until the Separation Date:

                           (i) no Right may be exercised; and

                           (ii) each Right will be evidenced by the certificate
                  for the associated Common Share and will be transferable only
                  together with, and will be transferred by a transfer of, such
                  associated Common Share. Notwithstanding any other provision
                  of this Agreement, any Rights held by the Company or any of
                  its Subsidiaries shall be void.

                  (c) After the Separation Date and prior to the Expiration
         Date, the Rights, unless earlier redeemed in accordance with the
         provisions of Article V hereof, may be exercised and will be
         transferable independent of Common Shares. Promptly following the
         Separation Date, the Rights Agent will mail to each holder of record of
         Common Shares as of the Separation Date, at such holder's address as
         shown by the records of the transfer agent and registrar of the
         Company's Common Shares (the Company hereby agreeing to cause such
         transfer agent and registrar, if different from the Rights Agent, to

                                       7
<PAGE>

         furnish copies of such records to the Rights Agent for this purpose):
         (i) a Rights Certificate appropriately completed, representing the
         number of Rights held by such holder at the Separation Date and having
         such marks of identification or designation and such legends,
         summaries, or endorsements printed thereon as the Company may deem
         appropriate and as are not inconsistent with the provisions of this
         Agreement, or as may be required to comply with any law or with any
         rule or regulation made pursuant thereto or with any rule or regulation
         of any stock exchange or quotation system on which the Rights may from
         time to time be listed or traded. or to conform to usage, and (ii) a
         disclosure statement describing the Rights.

                  (d) Rights may be exercised on any Business Day after the
         Separation Date and prior to the Expiration Date by submitting to the
         Rights Agent the Rights Certificate evidencing such Rights with an
         Election to Exercise (an "Election to Exercise"), substantially in the
         form attached to the Rights Certificate duly completed, accompanied by
         payment in cash or by certified check or money order payable to the
         order of the Company, of a sum equal to the Exercise Price multiplied
         by the number of Rights being exercised and a sum sufficient to cover
         any transfer tax or charge that may be payable in respect of any
         transfer involved in the transfer or delivery of Rights Certificates or
         the issuance or delivery of certificates for whole or fractional
         Preferred Shares in a name other than that of the holder of the Rights
         being exercised.

                  (e) Upon receipt of a Rights Certificate, with an Election to
         Exercise accompanied by payment as set forth in Section 2.2(d) above,
         the Rights Agent will thereupon promptly:

                           (i) requisition from any transfer agent of the
                  capital stock of the Company certificates for the number of
                  whole or fractional Preferred Shares to be purchased (the
                  Company hereby irrevocably authorizing and directing such
                  transfer agent to comply with all such requisitions);

                           (ii) as provided in Section 6.5(b) hereof, at the
                  election of the Company, cause depository receipts to be
                  issued in lieu of fractional shares;

                           (iii) when appropriate, requisition from the Company
                  the amount of cash to be paid in lieu of issuance of
                  fractional shares in accordance with Section 6.5(b) hereof;

                           (iv) when appropriate, requisition from the Company
                  the amount of cash or other consideration to be paid in lieu
                  of capital stock as determined pursuant to the terms hereof;
                  and

                           (v) after receipt of such certificates, depository
                  receipts, and/or cash or other consideration, deliver the same
                  to or upon the order of the registered holder of such Rights
                  Certificate, registered (in the case of certificates or
                  depository receipts) in such name or names as may be
                  designated by such holder.

                  (f) In case the holder of any Rights shall exercise less than
         all the Rights evidenced by such holder's Rights Certificate, a new
         Rights Certificate evidencing the Rights remaining unexercised will be
         issued by the Rights Agent to such holder or to such holder's duly
         authorized assigns.

                  (g) The Company covenants and agrees that it will:

                           (i) cause to be reserved and kept available out of
                  its authorized and unissued shares of preferred stock and
                  common stock, respectively, or out of authorized and issued
                  shares of preferred stock and common stock, respectively, held
                  in its treasury, such number of Preferred Shares and Common
                  Shares, respectively, as will from time to time be sufficient
                  to permit the exercise in full of all outstanding Rights;

                           (ii) not effect any amendment to the designation of
                  rights, privileges, and preferences for the Preferred Shares
                  or any amendment to the articles of incorporation of the
                  Company that would materially and adversely affect the rights,
                  privileges, or powers of the Preferred Shares (regardless of
                  whether there are then any holders of Preferred Shares),
                  without the prior approval of the holders of two-thirds or

                                       8
<PAGE>

                  more of the then-outstanding Preferred Shares and the prior
                  written consent of the holders of two-thirds or more of the
                  then-outstanding Rights that are not Beneficially Owned by any
                  Acquiring Person. (For purposes of the taking of any action by
                  the holders of Rights, the Company's Board of Directors may
                  establish a record date and may call and hold a meeting of
                  such holders or seek their consent to action by the requisite
                  number thereof in writing substantially in accordance with the
                  procedure applicable to action to be taken by the holders of
                  Preferred Shares and in accordance with applicable law);

                           (iii) take all such action as may be necessary and
                  within its power to ensure that all Preferred Shares delivered
                  upon exercise of Rights shall, at the time of delivery of the
                  certificates for such Preferred Shares (subject to payment of
                  the Exercise Price), be duly and validly authorized, executed,
                  issued, delivered, fully paid, and nonassessable;

                           (iv) take all such action as may be necessary and
                  within its power to comply with any applicable requirements of
                  the Securities Act or the Exchange Act, or the rules and
                  regulations thereunder and any other applicable law, rule, or
                  regulation, in connection with the issuance and delivery of
                  the Rights Certificates and the issuance of any Preferred
                  Shares upon exercise of Rights;

                           (v) use its best efforts to cause all Preferred
                  Shares issued upon exercise of Rights to be listed on a
                  national securities exchange (or on the same trading market as
                  are the shares of Company Common Stock) upon issuance; and

                           (vi) pay when due and payable any and all federal and
                  state transfer taxes (but not any income taxes of the holder
                  or exercising holder or any liability of the Company to
                  withhold tax) and charges that may be payable in respect of
                  the original issuance or delivery of the Rights Certificates;
                  provided that, the Company shall not be required to pay any
                  transfer tax or charge which may be payable in respect of any
                  transfer involved in the transfer or delivery of Rights
                  Certificates or the issuance or delivery of certificates for
                  shares in a name other than that of the holder of the Rights
                  being transferred or exercised.

         2.3 Adjustments to Exercise Price; Number of Rights.

                  (a) In the event the Company shall at any time after the
         Record Date and prior to the Expiration Date:

                           (i) declare or pay a dividend on the Common Shares
                  payable in Common Shares (or other capital stock or securities
                  exchangeable for or convertible into or giving a right to
                  acquire Common Shares or other capital stock) other than
                  pursuant to any optional stock dividend program;

                           (ii) subdivide or split the then-outstanding Common
                  Shares into a greater number of Common Shares;

                           (iii) combine or consolidate the then-outstanding
                  Common Shares into a smaller number of Common Shares or effect
                  a reverse split of the outstanding Common Shares; or

                           (iv) issue any Common Shares (or other capital stock
                  or securities exchangeable for or convertible into or giving a
                  right to acquire Common Shares or other capital stock) in
                  respect of, in lieu of, or in exchange for existing Common
                  Shares in a reclassification or recapitalization;

         then, and in each such event, the Exercise Price and the number of
         Rights outstanding, or, if the payment or effective date therefor shall
         occur after the Separation Date, the Preferred Shares purchasable upon
         exercise of Rights, shall be adjusted in the manner set forth below. If

                                       9
<PAGE>

         the Exercise Price and number of Rights outstanding are to be adjusted,
         (x) the Exercise Price in effect after such adjustment will be equal to
         the Exercise Price in effect immediately prior to such adjustment
         divided by the number of Common Shares (or other capital stock) (the
         "Expansion Factor") that a holder of one Common Share immediately prior
         to such dividend, subdivision, combination, or issuance would hold
         thereafter as a result thereof, and (xi) each Right held prior to such
         adjustment will become that number of Rights equal to the Expansion
         Factor, and the adjusted number of Rights will be deemed to be
         distributed among the Common Shares with respect to which the original
         Rights were associated (if they remain outstanding) and the shares
         issued in respect of such dividend, subdivision, combination, or
         issuance, so that each such Common Share (or other capital stock) will
         have exactly one Right associated with it. If the Preferred Shares
         purchasable upon exercise of Rights are split, subdivided, or combined,
         or if any dividend (whether of cash or securities) is declared with
         respect thereto, the Preferred Shares purchasable upon exercise of each
         Right after such event will be automatically adjusted to be that number
         of the Preferred Shares that a holder of the Preferred Shares
         purchasable upon exercise of one Right (regardless of whether a Right
         shall then be exercisable) immediately prior to such split,
         subdivision, combination, or dividend would hold thereafter as a result
         thereof. If after the Record Date and prior to the Expiration Date, the
         Company shall issue any shares of capital stock other than Common
         Shares in a transaction of a type described in the first sentence of
         this Section 2.3(a), shares of such capital stock shall be treated
         herein as nearly equivalent to Common Shares as may be practicable and
         appropriate under the circumstances, and the Company and the Rights
         Agent agree to amend this Agreement in order to effect such treatment,
         and the Company will not consolidate with, merge with or into, or enter
         into an arrangement with any other Person unless such Person agrees to
         be bound by the terms of an amendment effecting such treatment.

                  In the event the Company shall at any time after the Record
         Date and prior to the Separation Date issue any Common Shares otherwise
         than in a transaction referred to in the preceding paragraph, each such
         Common Share so issued shall automatically have one new Right
         associated with it, which Right shall be evidenced by the certificate
         representing such Share.

                  (b) In the event the Company shall at any time after the
         Record Date and prior to the Separation Date fix a record date for the
         making of a distribution to all holders of Common Shares of rights or
         warrants entitling them to subscribe for or purchase Common Shares (or
         securities convertible into or exchangeable for or carrying a right to
         purchase or subscribe for Common Shares) at a price per Common Share
         (or, if a security convertible into or exchangeable for or carrying a
         right to purchase or subscribe for Common Shares), having a conversion,
         exchange, or exercise price (including the price required to be paid to
         purchase such convertible or exchangeable security or right per share)
         less than the Market Price per Common Share on such record date, the
         Exercise Price shall be adjusted. The Exercise Price in effect after
         such record date will equal the Exercise Price in effect immediately
         prior to such record date multiplied by a fraction, of which the
         numerator shall be the number of Common Shares outstanding on such
         record date plus the number of Common Shares that the aggregate
         offering price of the total number of Common Shares so to be offered
         (and/or the aggregate initial conversion, exchange, or exercise price
         of the convertible or exchangeable securities or rights so to be
         offered (including the price required to be paid to purchase such
         convertible or exchangeable securities or rights)) would purchase at
         such Market Price, and of which the denominator shall be the number of
         Common Shares outstanding on such record date plus the number of
         additional Common Shares to be offered for subscription or purchase (or
         into which the convertible or exchangeable securities or rights so to
         be offered are initially convertible, exchangeable, or exercisable). In
         case such subscription price may be paid in a consideration part or all
         of which shall be in a form other than cash, the value of such
         consideration shall be as determined in good faith by the Company's
         Board of Directors. For purposes of this Agreement, the granting of the
         right to purchase Common Shares (whether from treasury shares or
         otherwise) pursuant to any dividend or interest reinvestment plan
         and/or any Common Share purchase plan providing for the reinvestment of
         dividends or interest payable on securities of the Company and/or the
         investment of periodic optional payments and/or employee benefit or
         similar plans (so long as such right to purchase is in no case
         evidenced by the delivery of rights or warrants) shall not be deemed to
         constitute an issue of rights or warrants by the Company; provided,
         however, that, in the case of any dividend or interest reinvestment
         plan, the right to purchase Common Shares is at a price per share of
         not less than ninety percent (90%) of the current market price per
         share (determined as provided in such plans) of the Common Shares.

                  (c) In the event the Company shall at any time after the
         Record Date and prior to the Separation Date fix a record date for the
         making of a distribution to all holders of Common Shares of evidences
         of indebtedness or assets (other than a regular periodic cash dividend
         or a dividend paid in Common Shares) or rights or warrants (excluding
         those referred to in Section 2.3(b)), the Exercise Price shall be
         adjusted. The Exercise Price in effect after such record date will
         equal the Exercise Price in effect immediately prior to such record
         date less the fair market value (as determined in good faith by the
         Company's Board of Directors) of the portion of the assets, evidences
         of indebtedness, rights, or warrants so to be distributed applicable to
         the securities purchasable upon exercise of one Right.

                  (d) Each adjustment made pursuant to this Section 2.3 shall be
         made as of:

                           (i) the record date for the applicable dividend or
                  distribution, in the case of an adjustment made pursuant to
                  subsection (b) or (c) above; and

                           (ii) the payment or effective date for the applicable
                  dividend, subdivision, change, combination, or issuance, in
                  the case of an adjustment made pursuant to subsection (a)
                  above.

                  (e) In the event the Company shall at any time after the
         Record Date and prior to the Separation Date issue any shares of
         capital stock (other than Common Shares), or rights or warrants to
         subscribe for or purchase any such capital stock or securities
         convertible into or exchangeable for any such capital stock, in a
         transaction referred to in clause (a)(i) or (a)(iv) above, if the Board
         of Directors acting in good faith determines that the adjustments
         contemplated by clauses (a), (b), and (c) above in connection with such
         transaction will not appropriately protect the interests of the holders
         of Rights, the Company may determine what other adjustments to the
         Exercise Price, number of Rights, and/or Preferred Shares purchasable
         upon exercise of Rights would be appropriate and, notwithstanding
         clauses (a), (b), and (c) above, such adjustments, rather than the
         adjustments contemplated by clauses (a), (b), and (c) above, shall be
         made. The Company and the Rights Agent shall amend this Agreement as
         appropriate to provide for such adjustments.

                  (f) Each adjustment to the Exercise Price made pursuant to
         this Section 2.3 shall be calculated to the nearest cent. Whenever an
         adjustment to the Exercise Price is made pursuant to this Section 2.3,
         the Company shall:

                           (i) promptly prepare a certificate setting forth such
                  adjustment and a brief statement of the facts accounting for
                  such adjustment;

                           (ii) promptly file with the Rights Agent and with
                  each transfer agent for the Common Shares a copy of such
                  certificate; and

                           (iii) mail a brief summary thereof to each holder of
                  Rights.

                  (g) Irrespective of any adjustment or change in the securities
         purchasable upon exercise of the Rights, the Rights Certificates
         theretofore and thereafter issued may continue to express the
         securities so purchasable that were expressed in the initial Rights
         Certificates issued hereunder.

         2.4 Date on Which Exercise is Effective.

         Each Person in whose name any certificate for Preferred Shares is
issued upon the exercise of Rights shall for all purposes be deemed to have
become the holder of record of such Preferred Shares represented thereby on, and
such certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered for exercise and payment of the

                                       11
<PAGE>

Exercise Price for such Rights (and any applicable transfer taxes and other
governmental charges payable by the exercising holder hereunder) was made;
provided, however, that if the date of such surrender and payment is a date upon
which the Preferred Share transfer books of the Company are closed, such Person
shall be deemed to have become the record holder of such Preferred Shares on,
and such certificate shall be dated, the next succeeding Business Day on which
the Preferred Share transfer books of the Company are open.

         2.5 Execution, Authentication, Delivery, and Dating of Rights
Certificates.

                  (a) The Rights Certificates shall be executed on behalf of the
         Company by its Chairman of the Board, President or one of its Executive
         Vice Presidents, attested by its Secretary or one of its Assistant
         Secretaries. The signature of any of these officers on the Rights
         Certificate may be manual or facsimile. Rights Certificates bearing the
         manual or facsimile signatures of individuals that were at any time the
         proper officers of the Company shall bind the Company, notwithstanding
         that such individuals or any of them have ceased to hold such offices
         prior to the countersignature and delivery of such Rights Certificates.

                  (b) Promptly after the Company learns of the Separation Date,
         the Company will notify the Rights Agent of such Separation Date and
         will deliver Rights Certificates executed by the Company to the Rights
         Agent for countersignature, and the Rights Agent shall countersign
         (manually or by facsimile signature in a manner satisfactory to the
         Company) and deliver such Rights Certificates to the holders of the
         Rights pursuant to Section 2.2(c) hereof. No Rights Certificate shall
         be valid for any purpose until countersigned by the Rights Agent as
         aforesaid.

                  (c) Each Rights Certificate shall be dated the date of
         countersignature thereof.

         2.6 Registration, Registration of Transfer and Exchange.

                  (a) The Company will cause to be kept a register (the "Rights
         Register") in which, subject to such reasonable regulations as it may
         prescribe, the Company will provide for the registration and transfer
         of Rights. The Rights Agent is hereby appointed "Rights Registrar" for
         the purpose of maintaining the Rights Register for the Company and
         registering Rights and transfers of Rights as herein provided. In the
         event that the Rights Agent shall cease to be the Rights Registrar, the
         Rights Agent will have the right to examine the Rights Register at all
         reasonable times.

                  (b) After the Separation Date and prior to the Expiration
         Date, upon surrender for registration of transfer or exchange of any
         Rights Certificate, and subject to the provisions of Section 2.6(d)
         below, the Company will execute, and the Rights Agent will countersign
         and deliver, in the name of the holder or the designated transferee or
         transferees, as required pursuant to the holder's instructions, one or
         more new Rights Certificates evidencing the same aggregate number of
         Rights as did the Rights Certificates so surrendered.

                  (c) All Rights issued upon any registration of transfer or
         exchange of Rights Certificates shall be the valid obligations of the
         Company, and such Rights shall be entitled to the same benefits under
         this Agreement as the Rights surrendered upon such registration of
         transfer or exchange.

                  (d) Every Rights Certificate surrendered for registration of
         transfer or exchange shall be duly endorsed, or be accompanied by a
         written instrument of transfer in form satisfactory to the Company or
         the Rights Agent, as the case may be, duly executed by the holder
         thereof or such holder's attorney duly authorized in writing. As a
         condition to the issuance of any new Rights Certificate under this
         Section 2.6, the Company may require the payment of a sum sufficient to
         cover any tax or other governmental charge that may be imposed in
         relation thereto.

         2.7 Mutilated, Destroyed, Lost, and Stolen Rights Certificates.

                  (a) If any mutilated Rights Certificates is surrendered to the
         Rights Agent prior to the Expiration Date, the Company shall execute
         and the Rights Agent shall countersign and deliver in exchange therefor

                                       12
<PAGE>

         a new Rights Certificate evidencing the same number of Rights as did
         the Rights Certificate so surrendered.

                  (b) If there shall be delivered to the Company and the Rights
         Agent prior to the Expiration Date (i) evidence to their satisfaction
         of the destruction, loss, or theft of any Rights Certificate, and (ii)
         such security or indemnity as may be required by them to save each of
         them and any of their agents harmless, then, in the absence of notice
         to the Company or the Rights Agent that such Rights Certificate has
         been acquired by a bona fide purchaser, the Company shall execute and
         upon its request the Rights Agent shall countersign and deliver, in
         lieu of any such destroyed, lost, or stolen Rights Certificate, a new
         Rights Certificate evidencing the same number of Rights as did the
         Rights Certificate so destroyed, lost, or stolen .

                  (c) As a condition to the issuance of any new Rights
         Certificate under this Section 2.7, the Company may require the payment
         of a sum sufficient to cover any tax or other governmental charge that
         may be imposed in relation thereto and any other expenses (including
         the fees and expenses of the Rights Agent) connected therewith.

                  (d) Every new Rights Certificate issued pursuant to this
         Section 2.7 in lieu of any destroyed, lost, or stolen Rights
         Certificate shall evidence an original additional contractual
         obligation of the Company, whether or not the destroyed, lost, or
         stolen Rights Certificate shall be at any time enforceable by anyone,
         and shall be entitled to all the benefits of this Agreement equally and
         proportionately with any and all other Rights duly issued hereunder.

         2.8 Persons Deemed Owners.

         Prior to due presentment of a Rights Certificate (or, prior to the
Separation Date, the associated Common Share certificate) for registration of
transfer, the Company, the Rights Agent, and any agent of the Company or the
Rights Agent may deem and treat the Person in whose name such Rights Certificate
(or, prior to the Separation Date, the associated Common Share certificate) is
registered as the absolute owner thereof and of the Rights evidenced thereby for
all purposes whatsoever. As used in this Agreement, unless the context otherwise
requires, the term "holder" of any Rights shall mean the registered holder of
such Rights (or, prior to the Separation Date, the associated Common Shares).

         2.9 Delivery and Cancellation of Certificates.

         All Rights Certificates surrendered upon exercise or for redemption,
registration of transfer, or exchange shall, if surrendered to any Person other
than the Rights Agent, be delivered to the Rights Agent and, in any case, shall
be promptly canceled by the Rights Agent. The Company may at any time deliver to
the Rights Agent for cancellation any Rights Certificates previously
countersigned and delivered hereunder that the Company may have acquired in any
manner whatsoever, and all Rights Certificates so delivered shall be promptly
canceled by the Rights Agent. No Rights Certificate shall be countersigned in
lieu of or in exchange for any Rights Certificates canceled as provided in this
Section 2.9, except as expressly permitted by this Agreement. The Rights Agent
shall destroy all canceled Rights Certificates and deliver a certificate of
destruction to the Company.

         2.10 Agreement of Rights Holders.

         Every holder of Rights by accepting the same consents and agrees with
the Company and the Rights Agent and with every other holder of Rights that:

                  (a) prior to the Separation Date, each Right will be
         transferable only together with, and will be transferred by a transfer
         of, the associated Common Share;

                  (b) after the Separation Date, the Rights Certificates will be
         transferable only on the Rights Register as provided herein;

                                       13
<PAGE>

                  (c) prior to due presentment of a Rights Certificate (or,
         prior to the Separation Date, the associated Common Share certificate)
         for registration of transfer, the Company, the Rights Agent, and any
         agent of the Company or the Rights Agent may deem and treat the Person
         in whose name the Rights Certificate (or, prior to the Separation Date,
         the associated Common Share certificate) is registered as the absolute
         owner thereof and of the Rights evidenced thereby (notwithstanding any
         notations of ownership or writing on such Rights Certificate or the
         associated Common Share certificate made by anyone other than the
         Company or the Rights Agent) for all purposes whatsoever, and neither
         the Company nor the Rights Agent shall be affected by any notice to the
         contrary; and

                  (d) without the approval of any holder of Rights and upon the
         sole authority of the Company's Board of Directors acting in good
         faith, this Agreement may be supplemented or amended from time to time
         pursuant to Section 6.3, Section 2.3(e), or the last sentence of the
         first paragraph of Section 2.3(a) hereof.

                                   ARTICLE III
                     ADJUSTMENTS TO THE RIGHTS IN THE EVENT
                             OF CERTAIN TRANSACTIONS

         3.1 Flip-over Transaction or Event.

                  (a) Subject to Section 3.3 hereof, in the event that prior to
         the Expiration Date the Company enters into, consummates, or permits to
         occur any Flip-over Transaction or Event, the Company shall take such
         action as shall be necessary to ensure, and shall not enter into,
         consummate, or permit to occur such Flip-over Transaction or Event
         until it shall have entered into a supplemental agreement with the
         principal Person engaging in such Flip-over Transaction or Event (the
         "Flip-over Entity," as such term is more specifically defined in
         Section 1.1(m) hereof) for the benefit of the holders of the Rights,
         providing that upon consummation of the Flip-over Transaction or Event:

                           (i) each Right shall thereafter constitute the right
                  to purchase from the Flip-over Entity, upon exercise thereof
                  in accordance with the terms hereof, that number of Common
                  Shares of such Flip-over Entity having an aggregate Market
                  Price on the date of consummation or occurrence of such
                  Flip-over Transaction or Event equal to twice the Exercise
                  Price for an amount in cash equal to the Exercise Price (such
                  right to be appropriately adjusted in a manner analogous to
                  the applicable adjustment to the Rights provided for in
                  Section 2.3 in the event that after such date of consummation
                  or occurrence an event of a type analogous to any of the
                  events described in Section 2.3 shall have occurred with
                  respect to such Common Shares);

                           (ii) the Flip-over Entity shall thereafter be liable
                  for, and shall assume, by virtue of such Flip-over Transaction
                  or Event and such supplemental agreement, all the obligations
                  and duties of the Company pursuant to this Agreement;

                           (iii) the term "Company" for all purposes of this
                  Rights Agreement shall thereafter be deemed to refer to such
                  Flip-over Entity;

                           (iv) such Flip-over Entity shall take such steps
                  (including the reservation of a sufficient number of its
                  Common Shares, in the same manner applicable to the
                  reservation of Preferred Shares provided by Section 2.2(g)(i)
                  hereof) in connection with the consummation of such Flip-over
                  Transaction or Event as may be necessary to assure that the
                  provisions hereof shall thereafter be applicable;

                           (v) confirming that all rights of first refusal or
                  preemptive rights in respect of the issuance of Common Shares
                  of the Flip-over Entity upon exercise of outstanding Rights

<PAGE>

                  have been waived and that such transaction shall not result in
                  a default by the Flip-over Entity under this Rights Agreement;
                  and

                           (vi) providing that, as soon as practicable after the
                  date of such Flip-over Transaction or Event, the Flip-over
                  Entity will:

                                    (1) prepare and file, as required by law, a
                           registration statement under the Securities Act with
                           respect to the Rights and the securities purchasable
                           upon exercise of the Rights on an appropriate form,
                           use its best efforts to cause such registration
                           statement to become effective as soon as practicable
                           after such filing, and use its best efforts to cause
                           such registration statement to remain effective (with
                           a prospectus at all times meeting the requirements of
                           the Securities Act), until the date of expiration of
                           the Rights, and similarly comply with applicable
                           state securities laws;

                                    (2) use its best efforts to list (or
                           continue the listing of) the Rights and the
                           securities purchasable upon exercise of the Rights on
                           a national securities exchange or to meet the
                           eligibility requirements for quotation on the Nasdaq
                           Stock Market; and

                                    (3) deliver to holders of the Rights
                           historical financial statements for the Flip-over
                           Entity that comply in all respects with the
                           requirements for registration on Form 10 (or any
                           successor form) under the Exchange Act.

         3.2 Flip-in Event.

                  (a) Subject to Section 3.3, in the event that prior to the
         Expiration Date a Flip-in Event shall occur, the Company shall take
         such action as shall be necessary to ensure and provide, within five
         Business Days or such longer period as may be required to satisfy the
         requirements of the Securities Act and the Exchange Act that, except as
         provided below, such Right shall thereafter constitute the right to
         purchase from the Company, upon exercise thereof in accordance with the
         terms hereof, that number of Common Shares of the Company having an
         aggregate Market Price on the date of consummation or occurrence of
         such Flip-in Event equal to the Exercise Price for an amount in cash
         equal to one-half the Exercise Price (such right to be appropriately
         adjusted in a manner analogous to the applicable adjustment provided
         for in Section 2.3 in the event that after such date of consummation or
         occurrence an event of a type analogous to any of the events described
         in Section 2.3 shall have occurred with respect to such Common Shares).

                  (b) Notwithstanding the foregoing, upon the occurrence of any
         Flip-in Event, any Rights that are or were Beneficially Owned on or
         after the earlier of the Separation Date or the Stock Acquisition Date
         by (i) an Acquiring Person or (ii) a transferee, direct or indirect, of
         an Acquiring Person (or any Affiliate or Associate of an Acquiring
         Person) in a transfer, whether or not for consideration, that the
         Company's Board of Directors acting in good faith has determined is
         part of a plan, arrangement, or scheme of an Acquiring Person (or any
         Affiliate or Associate of an Acquiring Person) that has the purpose or
         effect of avoiding clause (i) of this Section 3.2(b), shall become void
         and any holder of such Rights (including transferees) shall thereafter
         have no right to exercise such Rights under any provision of this
         Agreement.

                  (c) Any Rights Certificate issued pursuant to Section 2.2 that
         represents Rights Beneficially Owned by an Acquiring Person and any
         Rights Certificate issued at any time upon the transfer of any Rights
         to an Acquiring Person or any Affiliate or Associate thereof or to any
         nominee of any such Acquiring Person, Affiliate, or Associate, and any
         Rights Certificate issued upon transfer, exchange, replacement, or
         adjustment of any other Rights Certificate referred to in this
         sentence, shall contain the following legend:

                  The Rights represented by this Rights Certificate were issued
                  to a Person that was an Acquiring Person or an Affiliate or an
                  Associate of an Acquiring Person (as such terms are defined in

                                       15
<PAGE>

                  the Rights Agreement). This Rights Certificate and the Rights
                  represented hereby may become void in the circumstances
                  specified in Section 3.2(b) of the Rights Agreement.

         Provided that, the Rights Agent shall not be under any responsibility
         to ascertain the existence of facts that would require the imposition
         of such legend but shall be required to impose such legend only if
         instructed to do so by the Company, or if a holder fails to certify
         upon transfer or exchange in the space provided on the Rights
         Certificate that such holder is not an Acquiring Person or an Affiliate
         or Associate thereof; provided further, however, that the absence of
         such legend on any Rights Certificate shall not be deemed dispositive
         of whether the holder thereof is an Acquiring Person.

         3.3 Obligations of the Company.

                  (a) The Company shall not enter into or engage in any
         transaction of the kind referred to in this Article III if at the time
         of such transaction there are any rights, warrants, or securities
         outstanding or any other arrangements, agreements, or instruments that
         would eliminate or otherwise diminish in any respect the benefits
         intended to be afforded by this Rights Agreement to the holders of
         Rights upon consummation of such transaction. The provisions of this
         Article III shall apply to successive mergers or consolidations, sales,
         or other transfers.

                  (b) In the event that there shall not be sufficient Common
         Shares authorized to permit the exercise in full of the Rights in
         accordance with Section 3.2(a), holders of Rights will receive upon
         exercise Common Shares of the Company to the extent available and then
         cash, property, or other securities of the Company (which may be
         accompanied by a reduction in the Exercise Price), in proportions
         determined by the Company, so that the aggregate value received is
         equal to the Exercise Price.

                                   ARTICLE IV
                                THE RIGHTS AGENT

         4.1 General.

                  (a) The Company hereby appoints the Rights Agent to act as
         agent for the Company and the holders of Rights in accordance with the
         terms and conditions hereof, and the Rights Agent hereby accepts such
         appointment. The Company may from time to time appoint such Co-Rights
         Agents as it may deem necessary or desirable. In the event the Company
         appoints such Co-Rights Agents, the respective duties of the Rights
         Agents and Co-Rights Agents shall be as the Company may determine. The
         Company agrees to pay to the Rights Agent reasonable compensation for
         all services rendered by it hereunder and, from time to time on demand
         of the Rights Agent, its reasonable expenses and counsel fees and other
         disbursements incurred in the administration and execution of this
         Agreement and the exercise and performance of its duties hereunder. The
         Company also agrees to indemnify the Rights Agent for, and to hold it
         harmless against, any loss, liability, or expense, incurred without
         negligence, bad faith, or willful misconduct on the part of the Rights
         Agent, for anything done or omitted by the Rights Agent in connection
         with the acceptance and administration of this Agreement, including the
         costs and expenses of defending against any claim of liability, which
         right to indemnification will survive the termination of this
         Agreement.

                  (b) The Rights Agent shall be protected and shall incur no
         liability for or in respect of any action taken, suffered, or omitted
         by it in connection with its administration of this Agreement in
         reliance upon any certificate for Common Shares, Rights Certificate,
         certificate for other securities of the Company, instrument of
         assignment or transfer, power of attorney, endorsement, affidavit,
         letter, notice, direction, consent, certificate, statement, or other
         paper or document believed by it to be genuine and to be signed,
         executed and, when necessary, verified or acknowledged, by the proper
         Person or Persons.

         4.2 Merger or Consolidation or Change of Name of Rights Agent.

                  (a) Any corporation into which the Rights Agent or any
         successor Rights Agent may be merged or amalgamated or with which it
         may be consolidated, or any corporation resulting from any merger or
         consolidation to which the Rights Agent or any successor Rights Agent
         is a party, or any corporation succeeding to the stockholder services
         business of the Rights Agent or any successor Rights Agent, will be the
         successor to the Rights Agent under this Agreement without the
         execution or filing of any paper or any further act on the part of any
         of the parties hereto; provided that, such corporation would be
         eligible for appointment as a successor Rights Agent under the
         provisions of Section 4.4 hereof. In case at the time such successor
         Rights Agent succeeds to the agency created by this Agreement, any of
         the Rights Certificates have been countersigned but not delivered, any
         such successor Rights Agent may adopt the countersignature of the
         predecessor Rights Agent and deliver such Rights Certificates so
         countersigned; and in case at that time any of the Rights Certificates
         have not been countersigned, any successor Rights Agent may countersign
         such Rights Certificate either in the name of the predecessor Rights
         Agent or in the name of the successor Rights Agent; and in all such
         cases, such Rights Certificate will have full force provided in the
         Rights Certificates and in this Agreement.

                  (b) In case at any time the name of the Rights Agent is
         changed and at such time any of the Rights Certificate shall have been
         countersigned but not delivered, the Rights Agent may adopt the
         countersignature under its prior name and deliver Rights Certificate so
         countersigned; and in case at that time any of the Rights Certificates
         shall not have been countersigned, the Rights Agent may countersign
         such Rights Certificates either in its prior name or in its changed
         name; and in all such cases, such Rights Certificates shall have the
         full force provided in the Rights Certificates and in this Agreement.

         4.3 Duties of Rights Agent.

         The Rights Agent undertakes the duties and obligations imposed by this
Agreement upon the following terms and conditions, by all of which the Company
and the holders of Rights Certificates, by their acceptance thereof, shall be
bound:

                  (a) The Rights Agent may consult with legal counsel (who may
         be legal counsel for the Company), and the opinion of such counsel will
         be full and complete authorization and protection to the Rights Agent
         as to any action taken or omitted by it in good faith and in accordance
         with such opinion.

                  (b) Whenever in the performance of its duties under this
         Agreement the Rights Agent deems it necessary or desirable that any
         fact or matter be proved or established by the Company prior to taking
         or suffering any action hereunder, such fact or matter (unless other
         evidence in respect thereof be herein specifically prescribed) may be
         deemed to be conclusively proved and established by a certificate
         signed by a Person believed by the Rights Agent to be the Chairman of
         the Board, the President or any Executive Vice President or Vice
         President, and by the Treasurer or any Assistant Treasurer or the
         Secretary or any Assistant Secretary of the Company and delivered to
         the Rights Agent; and such certificate will be full authorization to
         the Rights Agent for any action taken or suffered in good faith by it
         under the provisions of this Agreement in reliance upon such
         certificate.

                  (c) The Rights Agent will be liable hereunder only for its own
         negligence, bad faith, or willful misconduct.

                  (d) The Rights Agent will not be liable for, or by reason of,
         any of the statements of fact or recitals contained in this Agreement
         or in the certificates for Common Shares or the Rights Certificates
         (except its countersignature thereof) or be required to verify the
         same, but all such statements and recitals are and will be deemed to
         have been made by the Company only.

                  (e) The Rights Agent will not be under any responsibility in
         respect of the validity of this Agreement or the execution and delivery

                                       17
<PAGE>

         hereof (except the due authorization, execution, and delivery hereof by
         the Rights Agent) or in respect of the validity or execution of any
         Common Share certificate, Preferred Share certificate, or Rights
         Certificate (except its countersignature thereof); nor will it be
         responsible for any breach by the Company of any covenant or condition
         contained in this Agreement or in any Rights Certificate; nor will it
         be responsible for any change in the exercisability of the Rights
         (including the Rights becoming void pursuant to Section 3.2(b) hereof
         or any adjustment required under the provisions of Section 2.3 hereof)
         or responsible for the manner, method, or amount of any such adjustment
         or the ascertaining of the existence of facts that would require any
         such adjustments (except with respect to the exercise of Rights after
         receipt of the certificate contemplated by Section 2.3 describing any
         such adjustment); nor will it by any act hereunder be deemed to make
         any representation or warranty as to the authorization of any Preferred
         Shares or Common Shares to be issued pursuant to this Agreement or any
         Rights or as to whether any Preferred Shares or Common Shares will,
         when issued, be duly and validly authorized, executed, issued,
         delivered, fully paid, and nonassessable.

                  (f) The Company agrees that it will perform, execute,
         acknowledge, and deliver, or cause to be performed, executed,
         acknowledged, and delivered, all such further and other acts,
         instruments, and assurances as may reasonably be required by the Rights
         Agent for the carrying out or performing by the Rights Agent of the
         provisions of this Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
         accept instructions with respect to the performance of its duties
         hereunder from any Person believed by the Rights Agent to be the
         Chairman of the Board, the President, any Executive Vice President or
         Vice President or the Secretary or any Assistant Secretary, or the
         Treasurer or any Assistant Treasurer of the Company, and to apply to
         such Persons for advice or instructions in connection with its duties
         and it shall not be liable for any action taken or suffered by it in
         good faith in accordance with instructions of any such Person.

                  (h) The Rights Agent and any stockholder, director, officer,
         or employee of the Rights Agent may buy, sell, or deal in Preferred
         Shares, Common Shares, Rights, or other securities of the Company or
         become pecuniarily interested in any transaction in which the Company
         may be interested, or contract with or lend money to the Company or
         otherwise act as fully and freely as though it were not the Rights
         Agent under this Agreement, subject to the terms, covenants,
         conditions, and restrictions of this Agreement. Nothing herein shall
         preclude the Rights Agent from acting in any other capacity for the
         Company or for any other legal entity.

                  (i) The Rights Agent may execute and exercise any of the
         rights or powers hereby vested in it or perform any duty hereunder
         either itself or by or through its attorneys or agents, and the Rights
         Agent will not be answerable or accountable for any act, default,
         neglect, or misconduct of any such attorneys or agents or for any loss
         to the Company resulting from any such act, default, neglect, or
         misconduct provided reasonable care was exercised in the selection and
         continued employment thereof.

         4.4 Change of Rights Agent.

         The Rights Agent may resign and be discharged from its duties under
this Agreement upon 90 days' notice (or such lesser notice as is acceptable to
the Company) in writing mailed to the Company and to each transfer agent of
Common Shares, by registered or certified mail, and to the holders of the Rights
in accordance with Section 6.9. The Company may remove the Rights Agent upon 30
days' notice in writing, mailed to the Rights Agent and to each transfer agent
of the Common Shares, by registered or certified mail, and to the holders of the
Rights in accordance with Section 6.9. If the Rights Agent should resign or be
removed or otherwise become incapable of acting, the Company will appoint a
successor to the Rights Agent. If the Company fails to make such appointment
within a period of 30 days after such removal or after it has been notified in
writing of such resignation or incapacity by the resigning or incapacitated
Rights Agent or by the holder of any Rights (which holder shall, with such
notice, submit such holder's Rights Certificate for inspection by the Company),
then the holder of any Rights may apply to any court of competent jurisdiction
for the appointment of a new Rights Agent. Any successor Rights Agent, whether
appointed by the Company or by such a court shall be a corporation incorporated
under the laws of the state of Utah or a province thereof authorized to carry on
the business of a trust company in the state of Utah. After appointment, the
successor Rights Agent will be vested with the same powers, rights, duties, and

                                       18
<PAGE>

responsibilities as if it had been originally named as Rights Agent without
further act or deed, but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent any property at the time held by it hereunder and
execute and deliver any further assurance, conveyance, act, or deed necessary
for the purpose. Not later than the effective date of any such appointment, the
Company will file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Common Shares and mail a notice thereof in
writing to the holders of the Rights. Failure to give any notice provided for in
this Section 4.4 however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

                                    ARTICLE V
                                   REDEMPTION

         5.1 Redemption.

         The Rights may be redeemed solely by action of the Board of Directors
pursuant to Section 5.2 hereof and in no other manner.

         5.2 By the Board of Directors.

         The Company's Board of Directors may, at its option, at any time prior
to the earlier of (a) the Expiration Date or (b) the Close of Business on the
tenth day after the Stock Acquisition Date (or such later date as may be
determined by the majority vote of the Board of Directors from time to time), by
notice to the Rights Agent and public announcement by the Company, redeem all,
but not less than all, of the then-outstanding Rights at the Redemption Price,
appropriately adjusted to reflect any stock split, stock dividend, or similar
transaction occurring after the date hereof, and the Company may, at its option,
pay the Redemption Price in Common Shares (based on the current Market Price of
the Common Shares at the time of redemption), cash, or any other form of
consideration deemed appropriate by the Board of Directors.

         5.3 Rights Termination.

         Immediately upon the action of the Company's Board of Directors
ordering the redemption of the Rights pursuant to Section 5.2 hereof, and
without any further action and without any notice, the right to exercise the
Rights will terminate and the only right thereafter of the holders of Rights
shall be to receive the Redemption Price. The Company shall promptly give public
notice of any such redemption; provided, however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within 10 days after such action of the Board of Directors ordering the
redemption of the Rights pursuant to Section 5.2 hereof, the Company shall mail
a notice of redemption to all the holders of the then-outstanding Rights at
their last addresses as they appear upon the registry books of the Rights Agent
or, prior to the Separation Date, on the registry books of the transfer agent
for the Common Shares of the Company, if different. Any notice that is mailed in
the manner herein provided shall be deemed given, whether or not the holder
receives the notice. Each such notice of redemption will state the method by
which the payment of the Redemption Price will be made. Neither the Company nor
any of its Affiliates or Associates may redeem any Rights at any time in any
manner other than that specifically set forth in this Article V, and other than
in connection with the purchase of Common Shares of the Company prior to the
Separation Date.

                                   ARTICLE VI
                                  MISCELLANEOUS

         6.1 Expiration.

         No Person shall have any right pursuant to this Agreement or in respect
of any Right after the Expiration Date, except the Rights Agent as specified in
Section 4.1(a) of this Agreement.

                                       19

         6.2 Issuance of New Rights Certificate.

         Notwithstanding any of the provisions of this Agreement or of the
Rights to the contrary, the Company may, at its option, issue new Rights
Certificates evidencing Rights in such form as may be approved by its Board of
Directors to reflect any adjustment or change in the number or kind or class of
shares purchasable upon exercise of Rights made in accordance with the
provisions of this Agreement.

         6.3 Supplements and Amendments.

         The Company may from time to time supplement or amend this Agreement
without the approval of any holders of Rights:

                  (a) to make any changes, except for a supplement or amendment
         that would establish an earlier Expiration Date or change the Exercise
         Price that the Board of Directors acting in good faith may deem
         necessary or desirable; provided that, no such supplement or amendment
         made on or after the Stock Acquisition Date shall materially adversely
         affect the interests of the holders of Rights generally; and provided
         further that, no such supplement or amendment shall be made to the
         provisions of Article IV except with the written concurrence of the
         Rights Agent to such supplement or amendment; or

                  (b) in order to cure any ambiguity or to correct or supplement
         any provision contained herein that may be inconsistent with any other
         provisions herein or otherwise defective.

         6.4 Fractional Rights.

                  (a) The Company shall not be required to issue fractions of
         Rights or Right Certificates evidencing fractional Rights.

                  (b) In lieu of fractional Rights, the registered holders of
         the Rights Certificates with regard to which such fractional Rights
         would otherwise be issuable shall be paid in cash an amount equal to
         the same fraction of the current Market Price of a whole Right. For the
         purposes of this Section 6.4, the current Market Price of a whole Right
         shall be the closing price of the Rights for the Trading Day
         immediately prior to the date on which such fractional Rights would
         have been otherwise issuable. The closing price of the Rights for any
         day shall be determined in the same manner set forth in Section 1.1(o).

         6.5 Fractional Shares.

                  (a) The Company shall not be required to issue fractions of
         Preferred Shares (other than fractions that are integral multiples of
         1/100 of a share) or fractions of a share of Common Shares upon
         exercise of the Rights or to distribute certificates that evidence
         fractional shares of Preferred Shares (other than fractions that are
         integral multiples of 1/100 of a share) or fractional shares of Common
         Shares. Nothing contained herein, however, shall be deemed to prevent
         any holder of Rights from aggregating the number of Rights exercised in
         any single transaction in such a manner that the aggregate number of
         Rights exercised in a single transaction may be convertible into an
         integral number of shares (or, in the case of Preferred Shares, an
         integral multiple of 1/100 of a share). A holder of fractional share
         certificates of Preferred Shares shall have all such rights,
         privileges, and preferences as it may be entitled to pursuant to the
         Utah Revised Business Corporation Act.

                  (b) In lieu of issuing fractions (other than fractions that
         are integral multiples of 1/100 of a share) of Preferred Shares, the
         Company may, at its election, issue depository receipts evidencing
         fractions of Preferred Shares pursuant to an appropriate agreement
         between the Company and a depository selected by it; provided that,
         such agreement shall provide that the holders of such depository
         receipts shall have all of the rights, privileges, and preferences to

                                       20

         which they would be entitled as owners of Preferred Shares pursuant to
         the Utah Revised Business Corporation Act. With respect to fractional
         Preferred Shares that are not integral multiples of 1/100 of a
         Preferred Share, if the Company does not issue such fractional
         Preferred Shares or depository receipts in lieu thereof, there shall be
         paid to the holders of record of Right Certificates at the time such
         Right Certificates are exercised as herein provided an amount in cash
         equal to the same fraction of the Market Price of a Preferred Share.

                  (c) The holder of a Right by the acceptance of a Right
         expressly waives its right to receive any fractional Preferred Shares
         (other than fractions that are integral multiples of 1/100 of a
         Preferred Share) upon exercise of a Right.

         6.6 Rights of Action.

         Subject to the terms of this Agreement, rights of action in respect of
this Agreement, other than rights of action vested solely in the Rights Agent,
are vested in the respective holders of the Rights, and any holder of any
Rights, without the consent of the Rights Agent or of the holder of any other
Rights, may, on such holder's own behalf and for such holder's own benefit and
the benefit of other holders of Rights, enforce, institute, and maintain any
suit, action, or proceeding against the Company to enforce, or otherwise act in
respect of, such holder's right to exercise such holder's Rights in the manner
provided in such holder's Rights Certificate and in this Agreement. Without
limiting the foregoing or any remedies available to the holders of Rights, it is
specifically acknowledged that the holders of Rights would not have an adequate
remedy at law for any breach of this Agreement and will be entitled to specific
performance of the obligations under, and injunctive relief against actual or
threatened violations of, the obligations of any Person subject to this
Agreement.

         6.7 Holder of Rights Not Deemed a Stockholder.

         No holder, as such, of any Rights shall be entitled to vote, receive
dividends, or be deemed for any purpose the holder of Preferred Shares or any
other securities that may at any time be issuable on the exercise of such
Rights, nor shall anything contained herein or in any Rights Certificate be
construed to confer upon the holder of any Rights, as such, any of the rights of
a stockholder of the Company or any right to vote for the election of directors
or upon any matter submitted to stockholders at any meeting thereof, or to give
or withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders (except as provided in Section 6.8 hereof),
or to receive dividends or subscription rights or otherwise, until such Rights
shall have been exercised in accordance with the provisions hereof.

                  (b) to effect the liquidation, dissolution, or winding up of
         the Company or the sale of all or substantially all of the Company's
         assets;

then, in each such case, the Company shall give to each holder of a Right, in
accordance with Section 6.9 hereof, a notice of such proposed action, which
shall specify the date on which such Flip-in Event or Flip-over Transaction or
Event, liquidation, dissolution, or winding up is to take place, and such notice
shall be so given at least 20 Business Days prior to the date of the taking of
such proposed action.

                                SENTO CORPORATION

                     AMENDMENT TO ARTICLES OF INCORPORATION
               DESIGNATING RIGHTS, PRIVILEGES, AND PREFERENCES OF
                           SERIES "A" PREFERRED STOCK

         Pursuant to the provisions of the Utah Revised Business Corporation
Act, section 16-10a-602, of the corporation laws of the state of Utah, the
undersigned corporation hereby adopts the following Amendment to Articles of
Incorporation Designating Rights, Privileges, and Preferences of Series "A"
Preferred Stock (the "Designation"):

         FIRST: The name of the Corporation is Sento Corporation

         SECOND: The following resolution amending the articles of incorporation
establishing a series of preferred stock designated as the "Series A
Participating Preferred Stock" consisting of 200,000 shares, no par value, was
duly adopted by the board of directors of the Corporation on May 28, 2005, in
accordance with the articles of incorporation of the Corporation and the
corporation laws of the state of Utah:

RESOLVED, there is hereby created a series of preferred stock of the Corporation
to be designated as the "Series "A" Preferred Stock" consisting of 200,000
shares, no par value, with the following powers, preferences, rights,
qualifications, limitations, and restrictions:

         1. Liquidation.

                  1.01 In the event of any voluntary or involuntary liquidation
         (whether complete or partial), dissolution, or winding up of the
         Corporation, the holders of the Series "A" Preferred Stock shall be
         entitled to be paid out of the assets of the Corporation available for
         distribution to its shareholders, whether from capital, surplus, or
         earnings, an amount in cash equal to all unpaid dividends, whether or
         not previously declared, accrued thereon to the date of final
         distribution subject to the priority distribution required respecting
         any issued and outstanding shares of any series of preferred stock
         authorized prior to the date hereof plus an amount per share equal to
         100 times the aggregate amount to be distributed per share to the
         holders of shares of Common Stock of the Corporation. No distribution
         shall be made on any common stock or other subsequent series of
         preferred stock of the Corporation by reason of any voluntary or
         involuntary liquidation (whether complete or partial), dissolution, or
         winding up of the Corporation unless each holder of any Series "A"
         Preferred Stock shall have received all amounts to which such holder
         shall be entitled under this subsection 1.01.

                  1.02 If on any liquidation (whether complete or partial),
         dissolution, or winding up of the Corporation, the assets of the
         Corporation available for distribution to holders of Series "A"
         Preferred Stock shall be insufficient to pay the holders of outstanding
         Series "A" Preferred Stock the full amounts to which they otherwise
         would be entitled under subsection 1.01, the assets of the Corporation
         available for distribution to holders of Series "A" Preferred Stock
         shall be distributed to them pro rata on the basis of the number of
         shares of Series "A" Preferred Stock held by each such holder.

         2. Voting Rights. The Series "A" Preferred Stock shall be voted with
the Common Stock as a single class and shall not be entitled to vote as a
separate class, except to the extent that the consent of the holders of the
Series "A" Preferred Stock, voting as a class, is specifically required by the
provisions of the corporation laws of the state of Utah, as now existing or as
hereafter amended. Each holder of Series "A" Preferred Stock shall be entitled
to 100 votes for each share of such stock held on all matters submitted to a
vote of the stockholders of the Corporation.

         3. Dividends.

                  3.01 The Corporation shall pay to the holders of the Series
         "A" Preferred Stock out of the assets of the Corporation at any time
         available for the payment of dividends at the times and in the amounts
         provided for in this section 3.

                  3.02 Subject to the rights of the holders of any shares of any
         series of preferred stock (or any similar stock) ranking prior and
         superior to the Series "A" Preferred Stock with respect to dividends,
         the holders of the shares of Series "A" Preferred Stock shall be
         entitled to receive, in preference to the holders of Common Stock and
         any other junior stock, dividends payable on the dates on which a
         dividend or distribution on the Common Stock is payable (other than a
         dividend payable in Common Stock), commencing on the first date on
         which such a dividend is payable after the first issuance of a share or
         fraction of a share of Series "A" Preferred Stock, in an amount per
         share (rounded to the nearest cent) equal to 100 times the aggregate
         per share amount of all cash dividends and 100 times the aggregate per
         share amount (payable in kind) of all non-cash dividends or other
         distributions (other than a dividend payable in shares of Common Stock
         or a subdivision of the outstanding shares of Common Stock, by
         reclassification or otherwise) declared on the Common Stock since the
         immediately preceding dividend payment date on the Common Stock, or, if
         later, the first issuance of any share or fraction of a share of Series
         "A" Preferred Stock.

                  3.03 Any payment of dividends declared and due under this
         section 3 with respect to any shares of Series "A" Preferred Stock
         shall be made by means of a check drawn on funds immediately available
         for the payment thereof to the order of the record holder of such share
         at the address for such record holder shown on the stock records
         maintained by or for the Corporation, which check shall be mailed by
         United States first class mail, postage prepaid. Any such payment shall
         be deemed to have been paid by the Corporation on the date that such
         payment is deposited in the United States mail as provided above;
         provided, that in the event the check or other medium by which any
         payment shall be made shall prove not to be immediately collectible on
         the date of payment, such payment shall not be deemed to have been made
         until cash in the amount of such payment shall actually be received by
         the person entitled to receive such payment.

                  3.04 Registration of transfer of any share of Series "A"
         Preferred Stock on the stock records maintained by or for the
         Corporation to a person other than the transferor shall constitute a
         transfer of any right which the transferor may have had to receive any
         accrued but unpaid dividends as of the date of transfer, whether
         declared or undeclared, and the Corporation shall have no further
         obligation to the transferor with respect to such accrued and unpaid
         dividends. Any shares of Series "A" Preferred Stock represented by a
         new certificate issued to a new holder shall continue to accrue
         dividends as provided in this section 3.

         4. Certain Restrictions.

                  4.01 Whenever any dividends or other distributions payable on
         the Series "A" Preferred Stock as provided herein are in arrears, until
         all accrued and unpaid dividends and distributions, whether or not
         declared, on shares of Series "A" Preferred Stock outstanding shall
         have been paid in full, the Corporation shall not:

                           (a) declare or pay dividends on or make any other
                  distributions on any shares of stock ranking junior (either as
                  to dividends or upon liquidation, dissolution or winding up)
                  to the Series "A" Preferred Stock;

                           (b) declare or pay dividends on or make any other
                  distributions on any shares of stock ranking on a parity
                  (either as to dividends or upon liquidation, dissolution or
                  winding up) with the Series "A" Preferred Stock except
                  dividends paid ratably on the Series "A" Preferred Stock and
                  all such parity stock on which dividends are payable or in
                  arrears in proportion to the total amounts to which the
                  holders of all such shares are then entitled;

                           (c) redeem, purchase or otherwise acquire for
                  consideration shares of any stock ranking junior (either as to
                  dividends or upon liquidation, dissolution or winding up) to
                  the Series "A" Preferred Stock, provided that the Corporation

                                      -2-
<PAGE>

                  may at any time redeem, purchase or otherwise acquire shares
                  of any such junior stock in exchange for shares of any stock
                  of the Corporation ranking junior (both as to dividends and
                  upon liquidation, dissolution or winding up) to the Series "A"
                  Preferred Stock; or

                           (d) redeem, purchase or otherwise acquire for
                  consideration shares of Series "A" Preferred Stock, or any
                  shares of stock ranking on a parity (either as to dividends or
                  upon liquidation, dissolution or winding up) with the Series
                  "A" Preferred Stock, except in accordance with a purchase
                  offer made in writing or by publication (as determined by the
                  Board of Directors) to all holders of Series "A" Preferred
                  Stock and other such shares (if any) upon such terms as the
                  Board of Directors, after consideration of the respective
                  annual preferences of the respective series and classes, shall
                  determine in good faith will result in fair and equitable
                  treatment among the respective series or classes.

         5. Redemption. The Corporation shall not have the right to redeem
shares of Series "A" Preferred Stock.

         6. Additional Provisions.

                  6.01 No change in the provisions of the Series "A" Preferred
         Stock set forth in this Designation affecting any interests of the
         holders of any shares of Series "A" Preferred Stock shall be binding or
         effective unless such change shall have been approved or consented to
         by the holders of a majority of the Series "A" Preferred Stock in the
         manner provided in the corporation laws of the state of Utah, as the
         same may be amended from time to time.

                  6.02 A share of Series "A" Preferred Stock shall be
         transferable only on the books of the Corporation maintained at its
         principal office, on delivery thereof duly endorsed by the holder or by
         his duly authorized attorney or representative or accompanied by proper
         evidence of succession, assignment, or authority to transfer. In all
         cases of transfer by an attorney, the original letter of attorney, duly
         approved, or an official copy thereof, duly certified, shall be
         deposited and remain with the Corporation. In case of transfer by
         executors, administrators, guardians, or other legal representatives,
         duly authenticated evidence of their authority shall be produced and
         may be required to be deposited and remain with the Corporation in its
         discretion. On any registration or transfer, the Corporation shall
         deliver a new certificate representing the share of Series "A"
         Preferred Stock so transferred to the person entitled thereto.

                  6.03 Any notice required or permitted to be given to the
         holders of the Series "A" Preferred Stock under this Designation shall
         be deemed to have been duly given if mailed by first class mail,
         postage prepared to such holders at their respective addresses
         appearing on the stock records maintained by or for the Corporation and
         shall be deemed to have been given as of the date deposited in the
         United States mail.

         THIRD: This amendment was duly adopted by the board of directors
without shareholder action, and shareholder action was not required.

         FOURTH: This amendment does not alter the preferences, limitations, or
relative rights granted to or imposed upon any wholly unissued class of shares
or any wholly unissued series of any class of shares.

                                      -3-

         THE RIGHTS ARE SUBJECT TO TERMINATION AT THE OPTION OF THE COMPANY ON
         THE TERMS SET FORTH IN THE RIGHTS AGREEMENT UNDER CERTAIN CIRCUMSTANCES
         (SPECIFIED IN SECTION 5.3 OF THE RIGHTS AGREEMENT). RIGHTS BENEFICIALLY
         OWNED BY AN ACQUIRING PERSON OR TRANSFEREES OF AN ACQUIRING PERSON OR
         ITS AFFILIATES OR ASSOCIATES (AS SUCH TERMS ARE DEFINED IN THE RIGHTS

                               Rights Certificate

         This certifies that _________________________________ or registered
assigns is the registered holder of the number of Rights set forth above, each
of which entitles the registered holder thereof, subject to the terms,
provisions, and conditions of the Rights Agreement dated as of the 3rd day of
June, 2005 (the "Rights Agreement"), between Sento Corporation, a Utah
corporation (the "Company"), and American Stock Transfer & Trust Company (the
"Rights Agent") (which term shall include any successor Rights Agent under the
Rights Agreement), to purchase from the Company at any time after the Separation
Date (as such term is defined in the Rights Agreement) and prior to the close of
business on the Expiration Date, one one-hundredth (1/100) of a share of Series
A Preferred Stock (a "Preferred Share") at the Exercise Price referred to below,
upon presentation and surrender of this Rights Certificate with the Form of
Election to Exercise duly executed and submitted to the Rights Agent at its
principal office at 6201 15th Avenue, Brooklyn, NY 11219. The Exercise Price
shall initially be One Hundred Dollars ($100.00) per Right and shall be subject
to adjustment in certain events as provided in the Rights Agreement.

         In certain circumstances described in the Rights Agreement, each Right
evidenced hereby may entitle the registered holder thereof to purchase or
receive securities of an entity other than the Company; assets, debt securities,
or shares in the capital stock of the Company other than Preferred Shares; or
more or less than one one-hundredth (1/100) of a Preferred Share (or a
combination thereof), all as provided in the Rights Agreement.

         This Rights Certificate is subject to all of the terms, provisions, and
conditions of the Rights Agreement which terms, provisions, and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties, and immunities thereunder of the
Rights Agent, the Company, and the holders of the Rights Certificates. Copies of
the Rights Agreement are on file at the principal executive office of the
Company and are available upon written request.

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at any of the offices of the Rights Agent designated for such
purpose, may be exchanged for another Rights Certificate or Rights Certificates
of like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate amount of securities as the Rights evidenced by the Rights Certificate
or Rights Certificates surrendered shall have entitled such holder to purchase.
If this Right Certificate shall be exercised in part, the registered holder
shall be entitled to receive, upon surrender hereof, another Rights Certificate
or Rights Certificates for the number of whole Rights not exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Certificate may be terminated by the Company under certain circumstances
at its option.

         No holder of this Rights Certificate, as such, shall be entitled to
vote or receive dividends or be deemed for any purpose the holder of Preferred
Shares or Fractional Preferred Shares or of any other securities which may at
any time be issuable upon the exercise hereof, nor shall anything contained in
the Rights Agreement or herein be construed to confer upon the holder hereof, as
such, any of the Rights of a shareholder of the Company or any right to vote for
the election of directors or upon any matter submitted to shareholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting shareholders (except as
provided in the Rights Agreement), or to receive dividends or subscription
rights or otherwise until the Rights evidenced by this Rights Certificate shall
have been exercised as provided in the Rights Agreement.

         This Rights Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by the Rights Agent.

         IN WITNESS WHEREOF, the facsimile signature of the proper officers of
the Company and its corporate seal.
