ITEM 2.   ACQUISITION OF ASSETS.

     On December 31, 1997, the Registrant executed an Amendment No. 1 to
Acquisition Agreement (the "Amendment") for the purpose of amending that
certain Acquisition Agreement (the "Acquisition Agreement"), dated November 19,
1997 by and among the Registrant, Astron Incorporated ("Astron"), and Jay
Barth, an individual and Astron's sole shareholder, and closed the transactions
contemplated by the Acquisition Agreement, as amended (collectively, the
"Acquisition"), consisting principally of the following:


     (a)  The Registrant acquired all of the issued and outstanding capital
          stock of Astron in exchange for the issuance to Mr. Barth of 180,000
          shares (the "Shares") of the Registrant's common stock, par value
          $0.25 per share.  The Acquisition was accomplished through a merger
          of Sento Acquisition, Inc., a newly formed and wholly-owned
          subsidiary of the Registrant ("Sento Acquisition"), with and into
          Astron.  Upon completion of the merger, the Registrant became the
          sole shareholder of Astron, the Articles of Incorporation and Bylaws
          of Sento Acquisition existing prior to the Acquisition became the
          Articles of Incorporation and Bylaws of Astron and the individuals
          serving as officers and directors of Sento Acquisition became the
          officers and directors of Astron.

     (b)  Mr. Barth deposited 36,000 of the Shares in escrow pursuant to the
          terms of a Stock Escrow Agreement securing certain indemnification
          and restrictive covenant obligations undertaken by Astron and Mr.
          Barth pursuant to the Acquisition Agreement, as amended.

     (c)  The Registrant executed employment agreements with Mr. Barth and
          Joseph J. Bunker, the President and Training Manager of Astron,
          respectively, pursuant to which the Registrant agreed to employ
          Messrs. Barth and Bunker as Director of Training and Education and
          Manager of Training and Education of Spire Technologies, Inc., a
          wholly owned subsidiary of the Registrant.

     Astron is a recognized provider of computer training and education courses
delivered nationwide.  Astron's certification training courses include
Microsoft MCSE (Microsoft Certified System Engineer) for Windows NT, Novell CNE
(Certified Novell Engineer), and Citrix CWA (Certified WinFrame Administrator).
The Registrant will account for the Acquisition as a purchase.

     The consideration paid by the Registrant in connection with the
Acquisition was determined through arms-length negotiations between the
Registrant and the other parties to the Acquisition, based upon the business,
assets, liabilities, operations and prospects of Astron.  The Acquisition was
funded by the issuance of the Shares without any borrowing of funds.  Prior to
the closing of the Acquisition, there was no material relationship between Mr.
Barth and the Registrant or any of its affiliates, any director or officer of
the Registrant or any associate of any such director or officer.

     Copies of the Acquisition Agreement, the Amendment, the other documents
described in this report, and press releases announcing the execution of the
Acquisition Agreement and the consummation of the Acquisition are attached to
this Report as Exhibits 2.1 through 2.2 and 4.1 through 4.2 and 99.1 through

                              Financial Statements

                    Nine months ended September 30, 1997 and
                     years ended December 31, 1996 and 1995

                  (With Independent Auditors' Report Thereon)



                          Independent Auditors' Report


The Board of Directors and Stockholders of
Astron Incorporated:



We have audited  the accompanying balance  sheets of Astron Incorporated  as of
September 30, 1997 and December  31, 1996 and 1995, and the  related statements
of operations,  stockholders' equity  (deficit), and  cash flows  for the  nine
months ended September  30, 1997 and  years ended December  31, 1996 and  1995.
These financial statements are the responsibility of  the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

We  conducted  our  audits  in  accordance  with  generally  accepted  auditing
standards.   Those  standards require  that we  plan and  perform the  audit to
obtain reasonable assurance about whether  the financial statements are free of
material misstatement.  An audit includes examining, on a test  basis, evidence
supporting the amounts and  disclosures in the financial statements.   An audit
also  includes  assessing  the  accounting  principles  used  and   significant
estimates made  by  management, as  well as  evaluating  the overall  financial
statement presentation.  We believe that our audits provide  a reasonable basis
for our opinion.

In our opinion,  the financial statements referred to  above present fairly, in
all  material respects,  the financial  position of  Astron Incorporated  as of
September  30, 1997  and December  31, 1996  and 1995, and  the results  of its
operations and its cash flows for the nine months ended September  30, 1997 and
years ended  December 31, 1996 and 1995,  in accordance with generally accepted
accounting principles.

                       Notes to the Financial Statements

Nine months ended September 30, 1997 and years ended December 31, 1996 and 1995



(1)  Summary of Significant Accounting Policies


(a)  Description of Business

     Astron Incorporated (the Company) provides education and training to the
information technology industry. The Company's focus is to enhance the
proficiency and skills of computer information system professionals and
students.  Courses are designed to assist participants to successfully complete
Novell Netware CNE and Microsoft MCSE testing and certification.  The Company's
customers consist of businesses, governmental entities, and individuals
geographically dispersed throughout the United States.

(b)  Accounts Receivable


     Accounts receivable consist primarily of sales proceeds  due from a
marketing company, which markets the Company's network training courses and
collects a major portion of the sales for network training.  The Company
performs ongoing credit evaluations of its customers and maintains an allowance
for possible losses.

(c)  Fixed Assets

     Fixed assets are recorded at cost.  Depreciation of equipment and office
equipment is computed primarily on accelerated methods.  Depreciation of
buildings is computed using the straight-line method.  Estimated useful lives
of the individual classes of assets are as follows:


          Buildings                27 - 39 years
          Equipment                5 - 7 years
          Office equipment         5 - 7 years

(d)  Income Taxes

     Income taxes are accounted for under the asset and liability method.
Under that method, deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases.  Deferred tax assets and liabilities are measured using

enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled.  The
effect on deferred tax assets and liabilities of the change in tax rates is
recognized in income in the period that includes the enactment date.

(e)  Revenue Recognition

     Revenue from training and seminars is recognized as the related service is
performed.  Deferred revenue consists of payments received in advance of
services provided and is recognized as revenue as the service is performed.
Equipment sales are recognized upon shipment.


(f)  Use of Estimates

     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets, liabilities, revenues and expenses, and
the disclosure of contingent assets and liabilities to prepare these financial
statements in conformity with generally accepted accounting principles.  Actual
results could differ from those estimates.


(2)  Other Assets

     Other assets consist of a life insurance policy for the president and
treasurer of the Company, prepaid deposits, employee advances, and a note

receivable from a related party discussed in note 6.


(3)  Long-term Debt

Long-term debt consist of the following:

                             ACQUISITION AGREEMENT


     THIS ACQUISITION AGREEMENT, dated as of November 19, 1997 (this
"Agreement"), by and among SENTO TECHNICAL INNOVATIONS CORPORATION, a Utah
corporation ("Sento"), ASTRON INCORPORATED, a Utah corporation ("Astron"), and
Jay Barth (the "Astron Shareholder").


                              W I T N E S S E T H:

     WHEREAS, Astron is in the business of software training and consulting
(the "Business");

     WHEREAS, the Astron Shareholder is the owner of all of the issued and
outstanding shares of the capital stock of Astron;

     WHEREAS, Sento desires to acquire all of the capital stock of Astron in
exchange solely for  400,000 shares of the voting common stock of Sento, $.25
par value (the "Sento Common Stock"), whereby Sento shall immediately
thereafter become the sole shareholder of Astron;

     WHEREAS, the respective Boards of Directors of Sento and Astron have
approved and adopted this Agreement providing for the acquisition by Sento of
all of the capital stock of Astron and the consummation of the related
transactions described in this Agreement (the "Acquisition") in exchange for
Sento's issuance of such shares of Sento Common Stock, upon the terms and
subject to the conditions set forth in this Agreement;

     WHEREAS, it is the intention of the parties that (i) for United States
federal income tax purposes, the Acquisition qualify as a reorganization under
Section 368(a)(1)(B) of the Internal Revenue Code of 1986, as amended (the
"Code"), and (ii) for accounting purposes, the Acquisition shall be recorded as
a purchase transaction; and

     WHEREAS, Sento, Astron and the Astron Shareholder desire to make certain
representations, warranties and agreements in connection with the Acquisition
and also to prescribe various conditions to the Acquisition.


                              A G R E E M E N T :

     NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties and agreements herein contained, Sento, Astron and
the Astron Shareholder agree as follows:

1.  THE ACQUISITION.

a.   ACQUISITION OF ASTRON CAPITAL STOCK.  Subject to the terms and conditions
of this Agreement, Sento or its designee will acquire all of the issued and
outstanding shares of the capital stock of Astron in exchange solely for shares
of Sento Common Stock, as set forth in Section 1(b) below.  As contemplated
pursuant to Section 12(m) below, Sento may assign its rights, duties,
obligations and interest under this Agreement to an affiliated entity.  Upon
such assignment, all rights, duties, obligations and interest of Sento
hereunder shall be transferred to Sento's designees and all references to Sento
in this Agreement shall be construed to apply to such designee on the same
basis as Sento.

b.   CONSIDERATION.  Subject to the provisions of Section 1(c) below, the total
consideration to be provided by Sento in exchange for the performance by Astron
and the Astron Shareholder of their respective obligations under this
Agreement, including, without limitation, the transfer to Sento of all of the
shares of capital stock of Astron, subject to all of the terms, covenants, and
conditions set forth herein, shall consist of 400,000 shares of Sento Common
Stock (the "Shares").  The Shares will be issued and delivered by Sento to the
Astron Shareholder at the Closing as contemplated by Section 2(b) below.

c.   ADJUSTMENTS.

i.   Prior to the Closing Date (as set forth in Section 2 below), Astron shall
obtain, at its expense, from a reputable certified public accounting firm
approved by Sento in advance, an audited balance sheet setting forth the
financial condition of Astron as of September 30, 1997 (the "Audited Balance
Sheet"), which Audited Balance Sheet shall be prepared in accordance with
generally accepted accounting principles, consistently applied ("GAAP").  In
the event the total shareholders' equity of Astron (the "Net Worth") shown on
the Audited Balance Sheet is less than $230,000, the number of Shares to be
delivered by Sento at the Closing shall be reduced by that number of Shares
(the "Share Reduction") having a value equal to the sum of (A) the product
obtained by multiplying (1) the amount by which the Net Worth shown on the
Audited Balance Sheet is less than $230,000 and (2) 1.25 and (B) the aggregate
amount of all legal, accounting and other professional expenses incurred by
Astron (or incurred by Sento for the benefit of Astron) during the period
between September 30, 1997 and the Closing Date.  The amount of the legal,
accounting and professional expenses is currently estimated to be approximately
$30,000; however, the actual amount of such expenses shall be determined by
Sento, in its reasonable discretion, at the Closing.

          ii.  Solely for purposes of illustration, Sento, Astron and the
          Astron Shareholder agree that the following hypothetical example
          illustrates the anticipated application of the adjustments described
          in Section 1(c)(i) above .  If the actual Net Worth, as shown on the
          Audited Balance Sheet, were $80,000 and the aggregate amount of
          legal, accounting and other professional expenses incurred by Astron
          between September 30, 1997 and the Closing Date were $40,000, then
          the amount of the adjustment would be equal to the sum obtained
          through the following equation: [($230,000 - $80,000) x (1.25)] +
          $40,000.  Accordingly, the amount of the adjustment would be equal to
          the sum of [($150,000)(1.25)] + $40,000 or ($187,500 + $40,000) or
          $227,500.

iii. For purposes of determining the number of Shares to be subject to the
adjustments described in this Section 1(c), the value of each of the Shares
shall be equal to the closing sale price for a share of the Sento Common Stock,
as reported by the National Association of Securities Dealers, Inc. (the
"NASD"), as of the Closing Date.  Each of Sento, Astron and the Astron
Shareholder acknowledges and agrees that, to the extent Sento is permitted to
reduce the number of Shares to be delivered at the Closing as permitted under
Section 1(c)(i) above or, in the event Sento discovers subsequent to the
Closing that the actual amount of the legal, accounting and professional fees
described in Section 1(c)(i)(B) above is greater than the estimate available at
the Closing, Sento is hereby authorized to instruct the escrow agent acting
pursuant to the terms of the Stock Escrow Agreement to return to Sento a number
of Shares equal to the aggregate amount of (A) the reduction in Shares and (B)
the amount by which the actual legal, accounting and professional fees exceeds
the estimate, which Shares shall be canceled by Sento and shall not be
delivered to the Astron Shareholder.

d.   ACCOUNTING FOR TRANSACTION.  The Acquisition will be accounted for as a
purchase transaction.

e.   RESTRICTIONS ON TRANSFER OF SHARES.  The Shares will not be registered
under the Securities Act of 1933, as amended (the "Securities Act"), and may
not be sold, transferred, or otherwise disposed of for value unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available, as evidenced by an opinion of counsel retained by
the Astron Shareholder and addressed to and reasonably satisfactory to Sento.
Each certificate evidencing the Shares shall be stamped or otherwise imprinted
with a legend substantially in the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "SECURITIES ACT"), AND ARE "RESTRICTED SECURITIES" WITHIN THE
          MEANING OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT.  THE
          SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD
          OR TRANSFERRED WITHOUT COMPLYING WITH RULE 144 IN THE ABSENCE OF
          AN EFFECTIVE REGISTRATION OR OTHER COMPLIANCE UNDER THE
          SECURITIES ACT. THE SECURITIES ARE SUBJECT TO ADDITIONAL
          RESTRICTIONS AS SET FORTH IN THAT CERTAIN ACQUISITION AGREEMENT,
          DATED AS OF NOVEMBER 19, 1997, BETWEEN SENTO TECHNICAL
          INNOVATIONS CORPORATION, A UTAH CORPORATION, ASTRON
          INCORPORATED, A UTAH CORPORATION, AND JAY BARTH.

2.  CLOSING.  The Closing of the Acquisition (the "Closing") shall be on a
date and at such time on or prior to January 2, 1998 as the parties may agree
(the "Closing Date"), following the satisfaction of every material term,
covenant or condition set forth herein that is required to be satisfied prior
to Closing.  At the Closing,

a.   the Astron Shareholder shall transfer and deliver to Sento certificates
evidencing all of the issued and outstanding shares of the common stock, no par
value, of Astron (the "Astron Common Stock"), constituting all of the capital
stock of Astron, Sento shall obtain and possess all rights in respect thereof,
and Astron shall become a wholly-owned subsidiary of Sento;

b.   subject to the provisions of the Stock Escrow Agreement described in the
following subsection, Sento shall issue and deliver to the Astron Shareholder
through such reasonable procedures as Sento may adopt, certificates evidencing
the number of shares of Sento Common Stock equal to 400,000, less (i) the
number of shares subject to the Share Reduction and (ii) the Escrowed Shares
(as defined below), constituting all of the Shares;

c.   Sento and the Astron Shareholder shall execute a Stock Escrow Agreement,
substantially in the form of Exhibit 2(c) (the "Stock Escrow Agreement")
attached hereto and incorporated herein by this reference, for the purpose of
securing the indemnification and restrictive covenant obligations of Astron and
the Astron Shareholder pursuant to Sections 1, 8 and 9 hereof, and Sento shall
deposit with the escrow agent identified in the Stock Escrow Agreement  84,000
Shares (the "Escrowed Shares"), on the terms and subject to the conditions set
forth in the Stock Escrow Agreement;

d.   Sento and Jay Barth shall execute an employment agreement, substantially
in the form of Exhibit 2(d) attached hereto and incorporated herein by this
reference, for the purpose of setting forth the terms and conditions upon which
Mr. Barth will be employed by Sento or any of its affiliates, including,
without limitation, Astron, as determined by Sento;

e.   each of the respective parties hereto shall execute, acknowledge and
deliver (or shall cause to be executed, acknowledged and delivered) any and all
documents, certificates, opinions, financial statements, schedules, agreements,
resolutions, rulings or other instruments required by this Agreement to be so
delivered at or prior to the Closing, together with such other items as may be
reasonably requested by the parties hereto and their respective legal counsel
in order to effectuate or evidence the transactions contemplated hereby;

f.   Each of Astron and the Astron Shareholder shall deliver to Sento the
certificates described in Section 7(a)(ii);

g.   Astron shall deliver to Sento the Audited Balance Sheet; and

h.   in addition to the foregoing, each of the parties shall execute and
deliver such additional documents as may reasonably be required in order to
effectuate the transactions herein contemplated in accordance with the
requirements of Section 368(a)(1)(B) of the Code and shall treat such
transactions for all tax purposes consistently with the other parties'
treatment thereof and with such other characterization as a reorganization
under such Code section.

3.  REPRESENTATIONS AND WARRANTIES CONCERNING ASTRON.  To induce Sento to
enter into this Agreement and to complete the Acquisition, except as fully and
accurately described in schedules to be prepared by Astron and delivered to
Sento prior to the execution of this Agreement (the "Astron Disclosure
Schedules"), each of Astron and the Astron Shareholder, jointly and severally,
represents and warrants that the following statements concerning the affairs of
Astron are true, correct and complete as of the date hereof, and will be true,
correct and complete as of the Closing Date.

          a.   ORGANIZATION, STANDING AND QUALIFICATION.  Astron is duly
     organized, validly existing and in good standing under the laws of the
     State of Utah and is authorized and qualified to own and operate its
     properties and assets and conduct its business in all jurisdictions where
     such properties and assets are owned and operated and such business is
     conducted.  Astron has all franchises, permits, licenses, and any similar
     authority necessary for the conduct of the Business as now being conducted
     by it, except where the lack of such would not materially adversely affect
     the Business or the financial condition of Astron.  Astron is not in
     default in any material respect under any of such franchises, permits,
     licenses or other similar authority.

          b.   CAPITALIZATION; SUBSIDIARIES.  The authorized capital stock of
     Astron consists solely of 100,000 shares of Astron Common Stock, of which
     50,000 shares and no more are issued and outstanding.  All of the
     outstanding shares of Astron Common Stock are duly authorized and validly
     issued and are fully paid and nonassessable.  There are no outstanding
     subscriptions, options, warrants, calls, contracts, demands, commitments,
     convertible securities or other rights, agreements or arrangements of any
     character or nature whatever relating to the issuance of capital stock or
     other securities of Astron.  No holder of any security of Astron is
     entitled to any preemptive or similar rights to purchase any securities of
     Astron.  Astron has no subsidiaries and no other investment in any entity.
     Astron is not a participant in any joint venture, partnership or other
     similar arrangement.

          c.   NO DEFAULTS.  Astron is not in default under or in violation of
     any provisions of its Articles of Incorporation or Bylaws.  Astron is not
     in default under or in violation of any restriction, lien, encumbrance,
     indenture, contract, agreement, lease, sublease, loan agreement, note or
     other obligation or liability relating to the Business.  Neither the
     execution and delivery of this Agreement nor consummation of the
     transactions contemplated hereby will conflict with or result in a breach
     of or constitute a default under any provision of the Articles of
     Incorporation or Bylaws of Astron, any law, rule, regulation, judgment,
     decree, order or other requirement, or any restriction, lien, encumbrance,
     indenture, contract, agreement, lease, sublease, loan agreement, note or
     other obligation or liability to which Astron is a party or by which it is
     bound, or to which any of its assets are subject, or result in the
     creation of any lien or encumbrance upon said assets or any loss to the
     Business or Sento.

          d.   CONSENTS AND APPROVALS.  Except as disclosed on Schedule 3(d) of
     the Astron Disclosure Schedules, the execution, delivery and performance
     of this Agreement and the consummation of the transactions contemplated
     hereby do not require Astron or the Astron Shareholder to obtain any
     consent, approval or action of, or make any filing with or give notice to
     any corporation, person or firm or any public, governmental or judicial
     authority.

          e.   RELATED-PARTY TRANSACTIONS.  Except as disclosed on Schedule
     3(e) of the Astron Disclosure Schedules, No employee, officer, director or
     shareholder of Astron or member of his or her  immediate family is
     indebted to Astron, nor is Astron indebted (or committed to make loans or
     extend or guarantee credit) to any such individuals.  To the knowledge of
     the Astron Shareholder, none of such individuals has any direct or
     indirect ownership interest in any firm or corporation with which Astron
     is affiliated or with which Astron has a business relationship, or any
     firm or corporation that competes with Astron.  No member of the immediate
     family of any employee, officer, director or shareholder of Astron is
     directly or indirectly interested in any material contract with Astron.

f.   COMPLIANCE WITH LAW.  Except as set forth on Schedule 3(f) of the Astron
Disclosure Schedules, to the knowledge of Astron and the Astron Shareholder,
neither Astron nor any of its directors, officers, fiduciaries, agents or
employees is in violation of any applicable statute, law, rule, regulation or
requirement of any governmental authority in any way relating to the Business
or Astron's operations and no material expenditure is or will be required in
order to comply with any such statute, law, rule, regulation or requirement.
Consummation of the transactions contemplated hereby will be in compliance with
all presently applicable laws, rules, regulations and requirements of all
governmental authorities without the necessity for any license or permit or
other action or permission in the nature thereof, or any registration with, or
consent of, any governmental authority.

          g.   FINANCIAL STATEMENTS.  The unaudited balance sheet of Astron,
     dated as of  September 30, 1997 (the "September 30 Balance Sheet"),
     attached hereto as Schedule 3(g) of the Astron Disclosure Schedules, is
     correct and complete and presents fairly in all material respects the
     financial condition of Astron as of such date, and has been prepared in
     accordance with GAAP.

          h.   TITLE TO ASSETS.  Astron has good and indefeasible title to and
     the right to and actual exclusive possession of all furniture, machinery,
     tools, equipment and other tangible assets used by Astron in the course of
     conducting the Business (the "Astron Assets").  The Astron Assets are free
     and clear of all liens, claims, security interests, encumbrances,
     restrictions and rights, title and interests in others.  There are no
     existing agreements, leases, subleases, options or commitments or rights
     with, to or in any third party to possess or acquire any of the Astron
     Assets or Astron or any interest therein, except for those entered into in
     the ordinary course of business and not materially adversely affecting the
     Astron Assets or property or any other right of Astron.  Except as
     disclosed on Schedule 3(h) of the Astron Disclosure Schedules, each such
     Astron Asset is free from defects (patent and latent), has been maintained
     in accordance with normal industry practice, is in good operating
     condition and repair (subject to normal wear and tear), and is suitable
     for the purposes for which it presently is used and presently is proposed
     to be used.

          i.   INTELLECTUAL PROPERTY.  Except as set forth on Schedule 3(i) of
     the Astron Disclosure Schedules, Astron owns all trade names, trademarks,
     service marks, copyrights, inventions, software, discoveries, ideas,
     research, engineering, methods, practices, processes, systems, formulae,
     designs, drawings, products, projects, improvements, developments,
     technology, know how, trade secrets and intellectual property which are
     used in the conduct of the Business, whether registered or unregistered,
     patentable or unpatentable and whether or not reduced to practice
     (collectively, the "Astron Intellectual Property").  Except as set forth
     on Schedule 3(i) of the Astron Disclosure Schedules, Astron created or
     developed all of the Astron Intellectual Property and the Astron
     Intellectual Property is not subject to any restriction, lien,
     encumbrance, right, title or interest in or of others.  All of the Astron
     Intellectual Property that is not in the public domain stands solely in
     the name of Astron and not in the name of any shareholder, director,
     officer, agent, partner or employee of Astron or any other person, and
     none of the same has any right, title, interest, restriction, lien or
     encumbrance therein or thereon or thereto.  Astron's ownership and use of
     the Astron Intellectual Property do not and will not interfere with,
     constitute a misappropriation of, infringe upon, conflict with or violate
     in any material respect any patent, trademark, service mark, copyright,
     trade secret or other lawful proprietary right of any other party, and no
     claim is pending or threatened to the effect that the operations of Astron
     interfere with, constitute a misappropriation of, infringe upon, conflict
     with or violate the rights of any other person under any proprietary right
     (including, without limitation, any claim that Astron must license,
     refrain from using or make royalty or other payments in respect of any
     intellectual property rights of any third party and/or the Astron
     Intellectual Property), and to the knowledge of Astron and the Astron
     Shareholder there is no reasonable basis (and no event has occurred that
     with the giving of notice or the passage of time or both would provide
     such reasonable basis) for any such claim (whether or not pending or
     threatened).  No claim is pending or, to the knowledge of Astron or the
     Astron Shareholder, threatened to the effect that any such Astron
     Property is invalid or unenforceable by Astron, and, to Astron's and the
     Astron Shareholder's knowledge, there is no reasonable basis for any such
     claim (whether or not pending or threatened).  Astron has obtained all
     licenses and consents necessary to permit Astron to use the intellectual
     property of other persons in the Business.  Astron has not been advised,
     nor, to the knowledge of the Astron Shareholder, is there any basis for
     any claim that Astron's proprietary rights are infringed by proprietary
     rights of any third party.

j.   REAL PROPERTY.  Schedule 3(j) of the Astron Disclosure Schedules lists and
describes briefly all real property that Astron owns.  Except as set forth on
Schedule 3(j) of the Astron Disclosure Schedules, with respect to each such
parcel of real property:  (i)  Astron has good and marketable fee simple title
to such parcel of real property free and clear of all liens, claims, security
interests, encumbrances, restrictions and rights, title and interests in others
(including, without limitation, easements, licenses and rights of way), (ii)
there are no existing agreements, leases, subleases, options or commitments or
rights with, to or in any third party to possess or acquire such parcel of real
property and (iii) such parcel abuts on and has direct vehicular access to a
public road. Astron does not use or possess any real property other than the
real property listed on such Schedule 3(j) and the real property subject to the
leases set forth on Schedule 3(k) of the Astron Disclosure Schedules.

          k.   LEASES.  Astron enjoys exclusive, peaceful and undisturbed
     possession under all leases to which it is a party.  All such leases are
     identified on Schedule 3(k) of the Astron Disclosure Schedules, are valid
     and enforceable in accordance with their terms against Astron and, to the
     knowledge of Astron and the Astron Shareholder, against the other parties
     thereto, and no party thereto is in default thereunder.

          l.   INVENTORY.  All finished goods, raw materials, merchandise,
     stock in trade, packaging materials, maintenance supplies and other
     inventory used in the Business (collectively, the "Inventory") are
     accurately reflected on the September 30 Balance Sheet, were valued at
     cost (determined on a first-in, first-out basis) or market, whichever is
     lower, with proper allowances for obsolescence, in accordance with GAAP.
     The Inventory consists of items which Astron reasonably believes are of
     quality and quantity readily usable or saleable in Astron's ordinary
     course of business, except such amounts as have been revised in accordance
     with GAAP and accurately reflected on the September 30 Balance Sheet.  No
     Inventory is stored or maintained at any location other than at the real
     property identified on Schedules 3(j) and 3(k).

          m.   LICENSES.  Each right or license to use the assets (tangible or
     intangible) or property (including, without limitation, intellectual
     property) of any other party which is material to the operation of the
     Business (each a "License" and collectively, the "Licenses") is identified
     on Schedule 3(m) of the Astron Disclosure Schedules.  Each License is, and
     at Closing shall be, in full force and effect and has not been assigned,
     modified, supplemented or amended, and neither Astron nor, to the
     knowledge of Astron or the Astron Shareholder, the licensor under any such
     License is in default under any such License, and, to the knowledge of
     Astron and the Astron Shareholder, no circumstances or state of facts
     presently exists which, with the giving of notice or passage of time, or
     both, would permit the licensor under any License to terminate any
     License.

          n.   MATERIAL CONTRACTS.  Other than as disclosed on Schedule 3(n) of
     the Astron Disclosure Schedules, Astron does not have, is not party to and
     may not be bound by any obligation, contract, agreement, lease, sublease,
     license, sublicense, commitment or understanding of any kind, nature or
     description that is material to the Business, whether oral or written,
     fixed or contingent, due or to become due, existing or inchoate (each a
     "Contract").  Astron has delivered to Sento a correct and complete copy of
     each written Contract listed on such Schedule 3(n) (as amended to date)
     and a written summary setting forth the terms and conditions of each oral
     Contract referred to on such Schedule 3(n).  With respect to each
     Contract: (i) the Contract is legal, valid, binding, enforceable, and in
     full force and effect; (ii) the Contract will continue to be legal, valid,
     binding, enforceable, and in full force and effect on identical terms
     following the consummation of the transactions contemplated hereby; (iii)
     no party is in breach or default, and no event has occurred which with
     notice or lapse of time would constitute a breach or default, or permit
     termination, modification, or acceleration, under the Contract; and (iv)
     no party has repudiated any provision of the Contract.

          o.   NO UNDISCLOSED LIABILITIES.  Except as set forth on Schedule
     3(o) of the Astron Disclosure Schedules, there are no material liabilities
     or obligations of Astron, including, without limitation, contingent
     liabilities for the performance of any obligation, except for liabilities
     or obligations which are fully and accurately disclosed on the September
     30 Balance Sheet in accordance with GAAP.  Without in any manner limiting
     the foregoing, all revenues attributable to Astron's business, operations
     and services have been properly accounted for in accordance with GAAP and
     all revenues, assets and liabilities attributable to any contract for such
     business, operations or services are accurately reflected on the September
     30 Balance Sheet in accordance with GAAP.

          p.   LITIGATION.  Except as disclosed in Schedule 3(p) of the Astron
     Disclosure Schedules: (i) there are no suits or proceedings at law or in
     equity, or before or by any governmental agency or arbitrator, pending or
     threatened, or to the knowledge of Astron or the Astron Shareholder,
     anticipated or contemplated, which in any way materially affect Astron;
     (ii) there are no unsatisfied or outstanding judgments, orders, decrees or
     stipulations which in any way affect Astron or its properties or assets or
     to which it is or may become a party; (iii) there are no claims against
     Astron pending or threatened, or to the knowledge of Astron or the Astron
     Shareholder, anticipated, or contemplated which, if valid, would
     constitute or result in a breach of any representation, warranty or
     agreement set forth herein; and (iv) there are no existing or, to the
     knowledge of Astron or the Astron Shareholder, anticipated or contemplated

Agreement and the Astron Disclosure Schedules, (ii)  Sento shall be deemed not
to have knowledge of any item or matter unless such item or matter is expressly
set forth in this Agreement or the Astron Disclosure Schedules and (iii) no
representation, warranty, covenant, undertaking or agreement of Astron and/or

4..  REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE ASTRON SHAREHOLDER.  The
consummation of the Acquisition constitutes the offer and sale of securities
under the Securities Act and applicable state statutes.  Such transactions
shall be consummated in reliance on exemptions from the registration and
prospectus delivery requirements of such statutes which depend, among other
items, on the circumstances under which the Astron Shareholder acquires such
securities.

a.   In order to provide documentation for reliance upon exemptions from the
registration and prospectus delivery requirements for such transactions, the
execution of this Agreement by the Astron Shareholder shall constitute his
affirmation and acceptance of, and concurrence in, the following
representations and warranties:

i.   the Astron Shareholder acknowledges that neither the Securities and
Exchange Commission (the "SEC") nor the securities commission of any state or
other federal agency has made any determination as to the merits of acquiring
the Shares, and that this transaction involves certain risks;

ii.  the Astron Shareholder (A) has such knowledge and experience in business
and financial matters that he is capable of evaluating Sento and its business
operations and (B) understands the risks related to the consummation of the
transactions contemplated hereby;

iii. the Astron Shareholder has been provided with a copy of this Agreement and
exhibits and schedules attached hereto, plus all materials and information
requested by him or his representative, including any information requested to
verify any information furnished (to the extent such information is available
or can be obtained without unreasonable effort or expense), and the Astron
Shareholder has been provided the opportunity for direct communication between
Sento and its representatives and the  Astron Shareholder and his
representatives regarding the transactions contemplated hereby;

iv.  all information which the Astron Shareholder has provided to Sento or its
agents or representatives concerning the Astron Shareholder's suitability to
hold shares of Sento Common Stock following the transactions contemplated
hereby is complete, accurate, and correct;

v.   the Astron Shareholder has not offered or sold any securities of Sento or
interest in this Agreement and has no present intention of dividing the Shares
or the rights under this Agreement with others or of reselling or otherwise
disposing of any portion of such Shares or rights, either currently or after
the passage of a fixed or determinable period of time or on the occurrence or
nonoccurrence of any predetermined event or circumstance;

vi.  the Astron Shareholder was at no time solicited by any leaflet, public
promotional meeting, circular, newspaper or magazine article, radio or
television advertisement or any other form of general advertising or
solicitation in connection with the offer, sale or purchase of the Shares
through this Agreement;

vii. the Astron Shareholder has adequate means of providing for his current
needs and possible personal contingencies and has no need now, and anticipates
no need in the foreseeable future, to sell the Shares that he will receive;

viii.     the Astron Shareholder is able to bear the economic risks of this
investment, and consequently, without limiting the generality of the foregoing,
is able to hold the Shares to be received in connection with the Acquisition
for an indefinite period of time and has a sufficient net worth to sustain a
loss of the entire investment, in the event such loss should occur;

ix.  the Astron Shareholder is (A) at least 21 years of age and (B) a bona fide
permanent resident of and is domiciled in the state or jurisdiction indicated
on the signature page hereof, and has no present intention of becoming a
resident of any other state or jurisdiction;

x.   the Astron Shareholder understands that the Shares have not been
registered, but are being acquired by reason of a specific exemption under the
Securities Act as well as exemptions under certain state statutes and that any
disposition of the Shares acquired in connection with the Acquisition may,
under certain circumstances, be inconsistent with these exemptions and may
cause the undersigned to be deemed an "underwriter" within the meaning of the
Securities Act (the Astron Shareholder understands that the definition of
"underwriter" arises out of the concept of "distribution" and that any
subsequent disposition of the Shares can only be effected in transactions which
are not considered distributions);

xi.  the Astron Shareholder acknowledges that the Shares must be held and may
not be sold, transferred, or otherwise disposed of for value unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available (Sento is under no obligation to register the Shares
to be acquired by the Astron Shareholder in connection with the Acquisition
under the Securities Act.  Sento's registrar and transfer agent will maintain
stop transfer orders against the transfer of the Shares to be obtained by the
Astron Shareholder in connection with the Acquisition, and the certificates
representing such Shares will bear a legend in substantially the form set forth
in Section 1(e)); and

xii. Sento may refuse to effect transfers of the Shares in the absence of
compliance with Rule 144 promulgated under the Securities Act unless the holder
furnishes Sento with a "no-action" or interpretive letter from the SEC or an
opinion of counsel reasonably acceptable to Sento stating that the transfer is
proper.  (Further, unless such interpretive letter or opinion states that the
Shares are free of any restrictions under the Securities Act, Sento may refuse
to transfer the Shares to any transferee who does not furnish in writing to
Sento the same representations and agree to the same conditions with respect to
such Shares as set forth herein.  Sento may also refuse to transfer the Shares
if any circumstances are present reasonably indicating that the transferee's
representations are not accurate.)

b.   The Astron Shareholder, for the purpose of inducing Sento to enter into
this Agreement, consummate the Acquisition and complete the other transactions
contemplated hereby, represents and warrants to, and covenants with, Sento as
follows:

i.   the Astron Shareholder is the legal and beneficial owner of the number of
shares of Astron Common Stock set forth below his name on the signature page
hereof, and all such shares are owned by the Astron Shareholder free and clear
of any lien, security interest, charge, encumbrance, pre-emptive right or other
restriction whatsoever;

ii.  the Astron Shareholder has not sold, transferred or delivered any interest
in the shares of Astron Common Stock to be transferred to Sento pursuant to the
terms of this Agreement, there are no outstanding options, warrants or other
rights to purchase, or claims against, such shares of Astron Common Stock to be
transferred by such Astron Shareholder and, upon delivery of such shares of
Astron Common Stock to Sento, Sento will acquire good and marketable title to
such shares, free and clear of any lien, claim, demand, encumbrance, security
interest, community property right or restriction on transfer;

iii. except as disclosed on Schedule 4(b) of the Astron Disclosure Schedules,
the Astron Shareholder is not required to obtain any consent, approval or
authorization or to make any filing with, any governmental authority or any
other person in connection with the execution of this Agreement and the
consummation of the Acquisition and the other transactions contemplated hereby;
and

iv.  the execution of this Agreement by the Astron Shareholder and the
consummation of the Acquisition and the other transactions contemplated hereby
will not violate, conflict with, result in a breach of, or constitute a default
under, any order of any governmental authority or any provision of any
indenture, mortgage, contract, instrument or other agreement to which such
Astron Shareholder is a party or by which he is bound.

c.   In order to more fully document reliance on the exemptions,
representations, warranties and covenants as provided herein, the Astron
Shareholder shall execute and deliver to Sento such letters of representation,
acknowledgment, suitability or the like, as Sento and its counsel may
reasonably request in connection with reliance on exemptions from registration
under such securities laws and confirmation of the foregoing representation,
warranties and covenants.

d.   The Astron Shareholder acknowledges that the basis for relying on
exemptions from registration or qualification under federal and state
securities laws are factual, depending on the conduct of the various parties,
and that no legal opinion or other assurance will be required of or given by
Sento, or counsel to Sento, to the effect that the transactions contemplated
hereby are in fact exempt from registration or qualification.


     5..  REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF SENTO.  Sento
represents and warrants that:

          a.   ORGANIZATION STANDING AND QUALIFICATION.  Sento is duly
     organized and validly existing and in good standing under the laws of the
     State of Utah, and is authorized and qualified to own and operate its
     properties and assets and conduct its business in all jurisdictions where
     such properties and assets are owned and operated and such business
     conducted, except where failure to so qualify would not have a material
     adverse effect on the business or financial condition of Sento.

          b.   AUTHORITY.  Sento has full right, power and authority to
     execute, deliver and perform the terms of this Agreement.  This Agreement

     filed with the SEC all required documents, and will timely file all
     required SEC documents between the date hereof and the Closing (all such

     of their respective dates, the Sento SEC Documents complied or will comply
     in all material respects with the requirements of the Securities Act or
     the Securities Exchange Act of 1934, as the case may be, and none of the
     Sento SEC Documents contained or will contain any untrue statement of a
     material fact or omitted or will omit to state a material fact required to
     be stated therein or necessary to make the statements therein, in light of
     the circumstances under which they were made, not misleading.  The
     consolidated financial statements of Sento included or to be included in
     the Sento SEC Documents comply as to form in all material respects with
     applicable accounting requirements and the published rules and regulations
     of the SEC with respect thereto, have been prepared in accordance with
     GAAP (except, in the case of the unaudited statements, as permitted by
     Form 10-QSB of the SEC) applied on a consistent basis during the periods
     involved (except as may be indicated therein or in the notes thereto) and
     fairly present the consolidated financial position of Sento and its
     consolidated subsidiaries as of the dates thereof and the consolidated
     results of their operations and statements of cash flows for the periods
     then ended (subject, in the case of unaudited statements, to normal
     year-end audit adjustments and to any other adjustments described
     therein).

b.   NOTICES AND CONSENTS.  The Astron Shareholder and Astron will give any

agencies in connection with the matters referred to in Section 3(d) and Section
4(b) above.

c.   OPERATION OF BUSINESS.  Astron will not engage in any practice, take any
action, or enter into any transaction outside the ordinary course of business.
Without limiting the generality of the foregoing Astron will not (i) declare,

stock, (ii) impose or permit to exist any security interest on any of Astron's
assets, tangible or intangible, (iii) make any capital expenditure outside the

notice to Sento of any material adverse development causing a breach of any of

disclosure by any party pursuant to this Section 6(f), however, shall be deemed
to amend or supplement the Astron Disclosure Schedules or to prevent or cure
any misrepresentation, breach of warranty, or breach of covenant.

g.   EXCLUSIVITY.  Neither the Astron Shareholder nor Astron will (i) solicit,
initiate, or encourage the submission of any proposal or offer from any person
relating to the acquisition of any capital stock or other voting securities, or
any substantial portion of the assets of, Astron (including any acquisition
structured as a merger, consolidation, or share exchange) or (ii) participate
in any discussions or negotiations regarding, furnish any information with
respect to, assist or participate in, or facilitate in any other manner any

stock of Astron owned (directly or indirectly) or controlled by him in favor of
any such acquisition structured as a merger, consolidation, or share exchange.
The Astron Shareholder will notify Sento immediately if any person makes any

of twelve (12) months for satisfaction of any claims of Sento under this
Section 8(a) (among other sections of this Agreement).  For purposes of this
Section 8, the value of each of the Shares shall be the closing sale price for
a share of the Sento Common Stock, as reported by the NASD, on the Closing
Date.  Except as provided in Section 8(c) below, this indemnity shall continue
in full force and effect subsequent to and notwithstanding the expiration,

except to the extent such are specifically set forth on the Audited Balance
Sheet and appropriate reserves for such have been made and reflected on the
Audited Balance Sheet: (A) any tax liability of Astron (including, without
limitation, all fines, penalties and assessments of any kind) or the Astron
Shareholder for periods prior to the Closing Date or (B) any items identified

with respect to Sento, Astron and their respective officers, directors,
employees and agents.

b.   SENTO'S OBLIGATIONS.  Subject to the limitations set forth in Section 8(c)
below, Sento agrees to indemnify, defend and hold Astron and the Astron
Shareholder harmless from any claims, liabilities, lawsuits, demands, actions,

of any breach of the agreements, covenants, representations or warranties of
Sento contained in this Agreement.  This indemnity shall continue in full force

actions, damages and expenses described in Section 8(c)(iii) below, the maximum
aggregate monetary amount for which the Astron Shareholder shall be liable to
Sento in connection with the indemnification obligations set forth in Section

occurrence of the third anniversary of the Closing Date, the Astron Shareholder
shall be liable for the full amount of any and all claims, liabilities,
lawsuits, demands, actions, damages and expenses resulting from (A) any
fraudulent conduct of the Astron Shareholder or (B) any representation made by
the Astron Shareholder which the Astron Shareholder knows or has reason to know
is false or misleading at the time such representation is made or at the

9.  RESTRICTIVE COVENANTS.

          a.   PROPRIETARY INFORMATION.  The Astron Shareholder acknowledges
     that his  relationship with Astron has created and may hereafter create a
     relationship of confidence and trust with respect to information of a
     confidential or secret nature that may be disclosed to him by Astron that
     relates to the business of Astron or to the business of any affiliate,
     customer, or supplier of Astron (collectively, the "Proprietary
     Information").

          Such Proprietary Information includes, but is not limited to, any
     information regarding inventions, marketing plans, product plans, business
     strategies, financial information, forecasts, personnel information,
     customer lists, software, hardware, processes, formulas, development or

     secret or confidential matter relating to the Business or any products,
     projects, programs, sales, customer lists, price lists, or data of Astron
     which is not generally known to the public.  At all times hereafter, the
     Astron Shareholder will keep all such Proprietary Information in
     confidence and trust, and will not use or disclose any of such Proprietary
     Information (except as may be required by law or to legal counsel or
     accountants) without the prior written consent of Sento, except as may be
     necessary to perform any duties he may now or hereafter have as an
     employee of Sento.  The  Astron Shareholder further agrees that at the
     Closing, and subsequently upon Sento's request or at the time of the
     termination of the Astron Shareholder's employment (if any) with Astron or
     Sento, as the case may be, the Astron Shareholder will deliver to Sento,
     and shall not retain for his own or others' use, any and all documents and
     any other materials and all copies thereof relating to his work, the
     Business and Astron's products, projects, programs and prospects of which
     the Astron Shareholder had knowledge, or which contain any Proprietary
     Information.

          b.   PUBLICITY.  Astron and the Astron Shareholder agree not to
     disclose to any person or entity, (except as may be required by law or to
     legal counsel or accountants) without the prior written consent of Sento,
     any of the terms of this Agreement at any time prior to Closing or
     thereafter, except as may be necessary for the performance of their
     obligations hereunder or the operation of Astron in the ordinary course of
     business.  Sento shall disclose and publicize this transaction in a press
     release the content of which shall be reasonably satisfactory to Astron
     and the Astron Shareholder or as required by law.

          c.   NON COMPETITION.

i.   The Astron Shareholder acknowledges that (A) Astron and Sento (including
certain of their respective subsidiaries and affiliates) are engaged in the
Business; (B) he is one of a limited number of persons who has performed a
significant role in developing the Business; (C) the Business is conducted
inside and outside the United States and can in a short time be conducted from
anywhere in and throughout the world; (D) his work for Astron and Sento has
given him, and will continue to give him, trade secrets of and confidential
information concerning Astron and Sento; (E) the agreements and covenants
contained in this Section 9(c) are essential to protect the Business and the
goodwill of Astron and Sento; and (F) he has means to support himself and his
dependents other than by engaging in the Business and the provisions of this
Section 9(c) will not impair such ability.

ii.  Without the prior written consent of Sento, from and after the Closing and
for a period of two (2) years thereafter (the "Restricted Period"), the Astron
Shareholder agrees not to engage in any Competitive Business (as defined below)
anywhere in the world.  As used herein, the term "Competitive Business" means
the Business or any other business activity which would compete with the
Business and shall include participation as an owner, shareholder, partner or
in any other capacity or solicitation of any officer or other employee of Sento
to terminate his  employment relationship with Sento or solicitation of any
customer of Sento to divert to any entity or person the business of such
customer.

iii. The Astron Shareholder acknowledges and agrees that the covenants in this
Section 9(c) are reasonable and valid in geographical and temporal scope and in
all other respects.  If any court determines that any of the covenants in this
Section 9(c), or any part thereof, is invalid or unenforceable, the remainder
of such covenants shall not thereby be affected and shall be given full effect,
without regard to the invalid portions.  Without limiting the generality of the
foregoing, if a court determines that the geographic scope of the covenants in
this Section 9(c) is unreasonable, then such scope shall be reduced to the
geographic area where Astron and/or Sento (including their respective
subsidiaries and affiliates) are engaged in the Business or such other
geographic area as the court shall determine to be reasonable in light of the
factors acknowledged by the Astron Shareholder in Section 9(c)(1) above.

d.   SECURITY.  As security for the obligations of Astron and the Astron
Shareholder pursuant to this Section 9 (among other sections of this
Agreement), at the Closing Sento and the Astron Shareholder shall enter into
the Stock Escrow Agreement, pursuant to which the Shares shall be available for
a period of twelve (12) months for satisfaction of any claims of Sento under
this Section 9.  The value of any Shares delivered in satisfaction of such
claims shall be equal to the closing sale price of an equal number of shares of
Sento Common Stock, as reported by the NASD, on the Closing Date.

     or desirable to effect, or to carry out the intent and purposes of the
     transactions contemplated hereby.

the Astron Shareholder and, to the extent any such fees or expenses are paid by
Sento (whether prior or subsequent to the Closing Date), the Astron Shareholder
shall reimburse Sento for the full amount of such fees and expenses promptly
upon Sento's request.  Sento, Astron and the Astron Shareholder agree that, (i)
upon the election of the Astron Shareholder, the number of Shares to be
delivered by Sento at the Closing may be reduced by an amount equal to the
estimated reimbursement amount and (ii) any amounts payable by the Astron
Shareholder pursuant to this Section 10(b) which remain unpaid subsequent to
the Closing Date, as determined by Sento in its reasonable discretion, may be
collected by Sento by instructing the escrow agent acting pursuant to the terms
of the Escrow Agreement to return to Sento a number of Shares equal to the
amount of the unpaid expenses, which Shares shall be canceled by Sento and
shall not be delivered to the Astron Shareholder.  In such event, the value of
each of the Shares shall be equal to the closing sale price for a share of
Sento Common Stock, as reported by the NASD, as of the Closing Date.

                                   AGREEMENT

     NOW, THEREFORE, upon these premises and in consideration of the covenants
and obligations set forth below and other good and valuable consideration, the
receipt, adequacy and legal sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

     1.   DEFINITIONS.  For purposes of this Agreement, the following terms

     corporation.

          (b)  "Claims" shall mean and refer collectively to all claims,
     liabilities, rights of offset, lawsuits, demands, actions, damages and
     expenses payable to Sento by Astron and the Shareholder pursuant to the
     provisions of the Acquisition Agreement; without limiting the foregoing,
     the failure of Astron or the Shareholder to perform any Obligation shall
     constitute a Claim for purposes of this Agreement.

          (c)  "Closing" and "Closing Date" shall mean and refer to the Closing
     and Closing Date, respectively, set forth in the Acquisition Agreement.

          (d)  "Default" shall have the meaning set forth in Section 4 below.

     evidencing the Escrowed Shares, accompanied by stock powers or other
     instruments of assignment duly executed by the Shareholder.

          (f)  "Escrowed Shares" shall mean and refer to 36,000 shares of
     Common Stock to be acquired by the Shareholder pursuant to the terms of

     4 below.

          (h)  "Obligations" shall mean and refer collectively to the

     3.   SECURITY FOR PERFORMANCE.  This Agreement is executed in connection
with the Acquisition Agreement and is made by the Shareholder as security for
the performance of each of the Obligations.  The parties acknowledge and agree
that Astron and the Shareholder have multiple and separate Obligations and that
the transfer to Sento of all or any part of the Escrowed Shares or the
satisfaction of any Claim(s) shall not diminish or alter the liability of
Astron or the Shareholder to satisfy any other Claim relating to any other
breach with respect to the same or any other Obligation.

     4.   DEFAULT; NOTICE OF DEFAULT.  The failure of Astron or the Shareholder
to timely perform any Obligation shall constitute a default under this
Agreement (a "Default").  In the event of any Default, Sento shall have the
right to pursue its remedies pursuant to the terms set forth herein so as to be
compensated for any Claim.  Upon the occurrence of any Default, Sento may, in
its discretion, give written notice to the Shareholder (the "Notice of
Default"), stating that a Default has occurred and setting forth a brief
description of the Default.

     5.   NOTICE TO THE ESCROW AGENT.  If Astron and the Shareholder fail to

representative of Sento (the "Default Certificate"), which shall (i) include a

delivered to the Shareholder at least ten (10) days prior to delivery of the
Default Certificate to the Escrow Agent; (iii) certify that Astron and the
Shareholder have failed to cure the Default within such ten (10) days; (iv)
certify that, in light of the foregoing, Sento is entitled to exercise its
right to have transferred to it all or a portion of the Escrowed Shares
pursuant to the terms of this Agreement; and (v) set forth the number of
Escrowed Shares to be transferred in accordance with the provisions of Section
6 below.

     6.   REMEDIES AND PROCEDURES.

          (a)  Upon delivery of the Default Certificate to the Escrow Agent,
     Sento may require that all or a portion of the Escrowed Shares necessary
     to satisfy the aggregate amount of all Claim(s) with respect to each
     Default hereunder be transferred to Sento.  In such event, the Escrow
     Agent shall cause a certificate or certificates representing such Escrowed
     Shares to be transferred into the name of Sento and delivered to Sento,
     whereupon Sento shall have all of the rights, privileges and powers
     appurtenant to and arising from ownership of such Escrowed Shares.

          (b)  Upon receipt of a Default Certificate, the Escrow Agent, without
     independent verification, shall release and deliver to Sento the Escrow
     Documents necessary to facilitate Sento's exercise of its remedies under
     this Agreement, and shall execute and deliver all such instruments or
     certificates and take all such actions as may be requested by Sento to
     accomplish Sento's exercise of such remedies.

          (c)  For purposes of determining the number of Escrowed Shares to be
     transferred to Sento pursuant to subsection (a) above, Sento shall divide
     the aggregate amount of all Claim(s) described in the applicable Default
     Certificate (expressed in dollars) by the closing sale price of the Common
     Stock, as reported by the National Association of Securities Dealers or
     such other established quotation service as Sento shall reasonably select,
     as of the Closing Date.

          (d)  If any or all of the Escrowed Shares are transferred to Sento
     pursuant to the provisions of this Section 6, the Shareholder shall pay
     any and all costs and expenses reasonably incurred by the Escrow Agent in
     connection with the delivery and transfer of the Escrowed Shares.

     7.   VOTING RIGHTS AND DIVIDENDS.  During the period that any Escrowed
Shares are held by the Escrow Agent pursuant to the provisions hereof, the
Shareholder shall remain the record owner of such Escrowed Shares and shall
possess all voting rights with respect thereto.  During such period, all cash
dividends declared with respect to such Escrowed Shares shall be paid or
distributed to the Shareholder.  The number of Escrowed Shares held by the
Escrow Agent pursuant to the terms of this Agreement shall be adjusted
proportionately for any increase or decrease in the number of issued shares of
Common Stock resulting from a subdivision or consolidation of shares of Common
Stock or the payment of a stock dividend or any other increase or decrease in
the number of issued shares of Common Stock effected without receipt of
consideration by Sento.  Similarly, if Sento is the surviving corporation in
any merger or consolidation, the number of Escrowed Shares held by the Escrow
Agent pursuant to the terms of this Agreement shall be adjusted to reflect the
number of securities to which a holder of the number of Escrowed Shares would
have been entitled as a result of such merger or consolidation.

     8.   TERMINATION.  This Agreement shall expire on the second anniversary
of the Closing Date, provided no uncured Default exists on the second
anniversary of the Closing Date and all Obligations arising during the period
between the Closing Date and the second anniversary of the Closing Date have
been performed or otherwise satisfied.  If, on the first anniversary of the
Closing Date, all Obligations arising during the period between the Closing
Date and such first anniversary have been performed shall deliver to the
Shareholder the Escrow Documents relating to 18,000 Escrowed Shares, less the
total number of Escrowed Shares transferred to Sento, as of the first
anniversary of the Closing Date, pursuant to the provisions of Section 6 above.
If, on the second anniversary of the Closing Date, all Obligations arising
during the period between the Closing Date and such second anniversary have
been performed and all Defaults hereunder have been resolved, the Escrow Agent
shall deliver to the Shareholder any Escrow Documents then remaining in escrow.
Otherwise, this Agreement shall continue beyond the applicable expiration date
until all such Defaults have been resolved and all Obligations have been
performed or otherwise satisfied.  Expiration of this Agreement and/or release
by the Escrow Agent of all or any part of the Escrowed Shares shall not
otherwise diminish or alter in any way the remaining duties and obligations of
Astron and the Shareholder under the Acquisition Agreement.

     9.   LIABILITY OF ESCROW AGENT.  The following provisions shall control
with respect to the rights, duties, liabilities, privileges and immunities of
the Escrow Agent:

          (a)  The Escrow Agent shall not be responsible for the genuineness of
     any certificate or signature and may rely conclusively upon and shall be
     protected when acting upon any notice, affidavit, request, consent,
     instruction, check or other instrument believed by it in good faith to be
     genuine or to be signed or presented by the proper person, or duly
     authorized, or properly made.  The Escrow Agent shall have no
     responsibility except for the performance of its express duties hereunder
     and no additional duties shall be inferred herefrom or implied hereby.

          (b)  No amendment or modification of this Agreement or waiver of its
     terms shall affect the rights and duties of the Escrow Agent unless its
     written consent thereto has been obtained.

          (c)  The Escrow Agent shall not be responsible or liable for any act
     or omission on its part in performing its duties as Escrow Agent under
     this Agreement unless such act or omission constitutes bad faith, gross
     negligence or fraud.
          (d)  The Escrow Agent shall not be required to institute or defend
     any action involving matters referred to herein or which affect it or its
     duties or liabilities hereunder unless or until requested to do so by any
     party to this Agreement and then only upon receiving full indemnity, in
     character satisfactory to the Escrow Agent, against all claims,
     liabilities and expenses in relation thereto.  In the event of any dispute
     among the parties with respect to the Escrow Agent or its duties, (i) the
     Escrow Agent may act or refrain from acting in respect of any matter
     referred to herein in full reliance upon any by and with the advice of
     counsel and shall be fully protected in so acting or in refraining from
     acting upon the advice of such counsel, or (ii) the Escrow Agent may
     refrain from acting until required to do so by an order of a court of
     competent jurisdiction.

                                   RECITALS

     WHEREAS, contemporaneously with the execution of this Agreement, Sento and
the Shareholder are entering into an Acquisition Agreement dated November 19,
1997, as amended by Amendment No.1 to Acquisition Agreement dated December 31,
1997 (as so amended, the "Acquisition Agreement"), pursuant to which, among
other things, Sento has agreed to issue to the Shareholder an aggregate of
180,000 shares of the Common Stock, $.25 par value, of Sento (the "Common
Stock");

     WHEREAS, as a condition to the obligations of Sento under the Acquisition
Agreement, the Shareholder has agreed to deposit in escrow 36,000 shares of
Common Stock to be issued to him by Sento under the terms of the Acquisition
Agreement, subject to the terms and conditions set forth in this Agreement; and

     WHEREAS, the Escrow Agent has agreed to undertake and perform its duties
and obligations as set forth in this Agreement.

                                   AGREEMENT

     NOW, THEREFORE, upon these premises and in consideration of the covenants
and obligations set forth below and other good and valuable consideration, the
receipt, adequacy and legal sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

     1.   DEFINITIONS.  For purposes of this Agreement, the following terms
shall have the meanings indicated:

          (a)  "Astron" shall mean and refer to Astron Incorporated, a Utah
     corporation.

          (b)  "Claims" shall mean and refer collectively to all claims,
     liabilities, rights of offset, lawsuits, demands, actions, damages and
     expenses payable to Sento by Astron and the Shareholder pursuant to the
     provisions of the Acquisition Agreement; without limiting the foregoing,
     the failure of Astron or the Shareholder to perform any Obligation shall
     constitute a Claim for purposes of this Agreement.

          (c)  "Closing" and "Closing Date" shall mean and refer to the Closing
     and Closing Date, respectively, set forth in the Acquisition Agreement.

          (d)  "Default" shall have the meaning set forth in Section 4 below.

          (e)  "Escrow Documents" shall mean and refer to the certificates
     evidencing the Escrowed Shares, accompanied by stock powers or other
     instruments of assignment duly executed by the Shareholder.

          (f)  "Escrowed Shares" shall mean and refer to 36,000 shares of
     Common Stock to be acquired by the Shareholder pursuant to the terms of
     the Acquisition Agreement and to be deposited with the Escrow Agent under
     the terms of this Agreement.

          (g)  "Notice of Default" shall have the meaning set forth in Section
     4 below.

          (h)  "Obligations" shall mean and refer collectively to the
     obligations of the Shareholder and Astron under the Acquisition Agreement,
     and each such obligation may be referred to individually as an
     "Obligation."

     2.   ESCROW.  On the Closing Date, the Shareholder agrees to deposit in
escrow with the Escrow Agent the Escrow Documents.  The Escrow Agent shall hold
and maintain the Escrow Documents in a safe and secure manner until it is
authorized to release the Escrow Documents in accordance with the provisions
set forth herein.  The Shareholder hereby agrees to pay all charges and fees
reasonably required by the Escrow Agent and any related costs or expenses
thereof.

     3.   SECURITY FOR PERFORMANCE.  This Agreement is executed in connection
with the Acquisition Agreement and is made by the Shareholder as security for
the performance of each of the Obligations.  The parties acknowledge and agree
that Astron and the Shareholder have multiple and separate Obligations and that
the transfer to Sento of all or any part of the Escrowed Shares or the
satisfaction of any Claim(s) shall not diminish or alter the liability of
Astron or the Shareholder to satisfy any other Claim relating to any other
breach with respect to the same or any other Obligation.

     4.   DEFAULT; NOTICE OF DEFAULT.  The failure of Astron or the Shareholder
to timely perform any Obligation shall constitute a default under this
Agreement (a "Default").  In the event of any Default, Sento shall have the
right to pursue its remedies pursuant to the terms set forth herein so as to be
compensated for any Claim.  Upon the occurrence of any Default, Sento may, in
its discretion, give written notice to the Shareholder (the "Notice of
Default"), stating that a Default has occurred and setting forth a brief
description of the Default.

     5.   NOTICE TO THE ESCROW AGENT.  If Astron and the Shareholder fail to
cure the Default within ten (10) days of receipt of the Notice of y authorized
representative of Sento (the "Default Certificate"), which shall (i) include a
copy of the Notice of Default; (ii) certify that the Notice of Default was
delivered to the Shareholder at least ten (10) days prior to delivery of the
Default Certificate to the Escrow Agent; (iii) certify that Astron and the
Shareholder have failed to cure the Default within such ten (10) days; (iv)
certify that, in light of the foregoing, Sento is entitled to exercise its
right to have transferred to it all or a portion of the Escrowed Shares
pursuant to the terms of this Agreement; and (v) set forth the number of
Escrowed Shares to be transferred in accordance with the provisions of Section
6 below.

     6.   REMEDIES AND PROCEDURES.

          (a)  Upon delivery of the Default Certificate to the Escrow Agent,
     Sento may require that all or a portion of the Escrowed Shares necessary
     to satisfy the aggregate amount of all Claim(s) with respect to each
     Default hereunder be transferred to Sento.  In such event, the Escrow
     Agent shall cause a certificate or certificates representing such Escrowed
     Shares to be transferred into the name of Sento and delivered to Sento,
     whereupon Sento shall have all of the rights, privileges and powers
     appurtenant to and arising from ownership of such Escrowed Shares.

          (b)  Upon receipt of a Default Certificate, the Escrow Agent, without
     independent verification, shall release and deliver to Sento the Escrow
     Documents necessary to facilitate Sento's exercise of its remedies under
     this Agreement, and shall execute and deliver all such instruments or
     certificates and take all such actions as may be requested by Sento to
     accomplish Sento's exercise of such remedies.

          (c)  For purposes of determining the number of Escrowed Shares to be
     transferred to Sento pursuant to subsection (a) above, Sento shall divide
     the aggregate amount of all Claim(s) described in the applicable Default
     Certificate (expressed in dollars) by the closing sale price of the Common
     Stock, as reported by the National Association of Securities Dealers or
     such other established quotation service as Sento shall reasonably select,
     as of the Closing Date.

          (d)  If any or all of the Escrowed Shares are transferred to Sento
     pursuant to the provisions of this Section 6, the Shareholder shall pay
     any and all costs and expenses reasonably incurred by the Escrow Agent in
     connection with the delivery and transfer of the Escrowed Shares.

     7.   VOTING RIGHTS AND DIVIDENDS.  During the period that any Escrowed
Shares are held by the Escrow Agent pursuant to the provisions hereof, the
Shareholder shall remain the record owner of such Escrowed Shares and shall
possess all voting rights with respect thereto.  During such period, all cash
dividends declared with respect to such Escrowed Shares shall be paid or
distributed to the Shareholder.  The number of Escrowed Shares held by the
Escrow Agent pursuant to the terms of this Agreement shall be adjusted
proportionately for any increase or decrease in the number of issued shares of
Common Stock resulting from a subdivision or consolidation of shares of Common
Stock or the payment of a stock dividend or any other increase or decrease in
the number of issued shares of Common Stock effected without receipt of
consideration by Sento.  Similarly, if Sento is the surviving corporation in
any merger or consolidation, the number of Escrowed Shares held by the Escrow
Agent pursuant to the terms of this Agreement shall be adjusted to reflect the
number of securities to which a holder of the number of Escrowed Shares would
have been entitled as a result of such merger or consolidation.

     8.   TERMINATION.  This Agreement shall expire on the second anniversary
of the Closing Date, provided no uncured Default exists on the second
anniversary of the Closing Date and all Obligations arising during the period
between the Closing Date and the second anniversary of the Closing Date have
been performed or otherwise satisfied.  If, on the first anniversary of the
Closing Date, all Obligations arising during the period between the Closing
Date and such first anniversary have been performed shall deliver to the
Shareholder the Escrow Documents relating to 18,000 Escrowed Shares, less the
total number of Escrowed Shares transferred to Sento, as of the first
anniversary of the Closing Date, pursuant to the provisions of Section 6 above.
If, on the second anniversary of the Closing Date, all Obligations arising
during the period between the Closing Date and such second anniversary have
been performed and all Defaults hereunder have been resolved, the Escrow Agent
shall deliver to the Shareholder any Escrow Documents then remaining in escrow.
Otherwise, this Agreement shall continue beyond the applicable expiration date
until all such Defaults have been resolved and all Obligations have been
performed or otherwise satisfied.  Expiration of this Agreement and/or release
by the Escrow Agent of all or any part of the Escrowed Shares shall not
otherwise diminish or alter in any way the remaining duties and obligations of
Astron and the Shareholder under the Acquisition Agreement.

     9.   LIABILITY OF ESCROW AGENT.  The following provisions shall control
with respect to the rights, duties, liabilities, privileges and immunities of
the Escrow Agent:

          (a)  The Escrow Agent shall not be responsible for the genuineness of
     any certificate or signature and may rely conclusively upon and shall be
     protected when acting upon any notice, affidavit, request, consent,
     instruction, check or other instrument believed by it in good faith to be
     genuine or to be signed or presented by the proper person, or duly
     authorized, or properly made.  The Escrow Agent shall have no
     responsibility except for the performance of its express duties hereunder
     and no additional duties shall be inferred herefrom or implied hereby.

          (b)  No amendment or modification of this Agreement or waiver of its
     terms shall affect the rights and duties of the Escrow Agent unless its
     written consent thereto has been obtained.

          (c)  The Escrow Agent shall not be responsible or liable for any act
     or omission on its part in performing its duties as Escrow Agent under
     this Agreement unless such act or omission constitutes bad faith, gross
     negligence or fraud.
          (d)  The Escrow Agent shall not be required to institute or defend
     any action involving matters referred to herein or which affect it or its
     duties or liabilities hereunder unless or until requested to do so by any
     party to this Agreement and then only upon receiving full indemnity, in
     character satisfactory to the Escrow Agent, against all claims,
     liabilities and expenses in relation thereto.  In the event of any dispute
     among the parties with respect to the Escrow Agent or its duties, (i) the
     Escrow Agent may act or refrain from acting in respect of any matter
     referred to herein in full reliance upon any by and with the advice of
     counsel and shall be fully protected in so acting or in refraining from
     acting upon the advice of such counsel, or (ii) the Escrow Agent may
     refrain from acting until required to do so by an order of a court of
     competent jurisdiction.

                                  Article III

                     Manner and Basis of Converting Shares

     The manner and basis of converting shares of the common stock of the
Constituent Corporations and the mode of carrying the Merger into effect are as
follows:

          (a)  Each share of Common Stock of Astron outstanding on the
               Effective Date shall, without any action on the part of the
               holder thereof, be converted into the right to receive Three and
               60/100 (3.60) Shares which shall, on such conversion, be validly
               issued and outstanding, fully paid and nonassessable, and shall
               not be liable to any further call, nor shall the holder thereof
               be liable for any further payments with respect thereto.  After
               the Effective Date, each holder of an outstanding certificate
               which prior thereto represented shares of Common Stock of Astron
               shall be entitled, on surrender thereof to Sento, to receive in
               exchange therefor a certificate or certificates representing the
               number of whole Shares into which the shares of Common Stock of
               Astron so surrendered shall be converted as aforesaid.  Until so
               surrendered, each such outstanding certificate (which prior to
               the Effective Date represented shares of Common Stock of Astron)
               shall for all purposes evidence the ownership of the Shares into
               which such shares of Common Stock of Sento shall have been
               converted; PROVIDED, that dividends or other distributions which
               are payable in respect of Shares into which shares of Common
               Stock of Astron shall have been converted shall be set aside by
               Sento and shall not be paid to any holder of certificates
               representing such shares of Common Stock of Astron until such
               certificates shall have been surrendered in exchange for
               certificates representing the Shares.  On such surrender, each
               holder that so surrenders such shares of Astron Common Stock
               shall be entitled to receive such dividends or other
               distributions without interest.  Sento shall not issue any
               fractional interest in any Shares in connection with the
               aforesaid conversion, and the aggregate number of Shares that
               each holder of shares of Common Stock of Astron shall be
               entitled to receive shall be rounded to the nearest whole number
               in the event of fractions (with 0.5 being rounded up); PROVIDED,
               FURTHER, that the number of Shares which the Astron Shareholder
               shall be required to deposit with Parr, Waddoups, Brown, Gee &
			   Loveless, as escrow agent  (the "Escrow Agent") pursuant to that
			   certain Escrow Agreement, dated December 31, 1997, among the Astron
               Shareholder, Sento and the Escrow Agent (the "Escrow Agreement")
               shall be withheld by Sento and issued to the Escrow Agent, to be
               later released to the Astron Shareholder pursuant to and in
               accordance with the Escrow Agreement and to the extent such
               Shares have not been made subject to claims of Sento against the
               Company and/or the Astron Shareholder pursuant to and in
               accordance with the Acquisition Agreement and the Escrow
               Agreement.

          (b)  All Shares into which shares of the Common Stock of Astron shall
               have been converted pursuant to this Article III shall be issued
               in full satisfaction of all rights pertaining to the shares of
               Common Stock of Astron, as applicable, and all shares of Common
               Stock of Astron shall be canceled.

          (c)  If any certificate for Shares is to be reissued in a name other
               than that in which the certificate surrendered in exchange
               therefor is registered, it shall be a condition of the issuance
               thereof that the certificate so surrendered shall be properly
               endorsed and otherwise in proper form for transfer and that the
               transfer be in compliance with applicable federal and state
               securities laws.

          (d)  On the Effective Date, the issued and outstanding shares of
               Common Stock of Sento Acquisition shall automatically be
               converted into 1,000 shares of the Surviving Corporation's
               common stock, no par value.

the Signing Bonus, the "Additional Compensation"), as the Boards of Directors
of the Company and/or Spire (or any committee thereof) may, at their
discretion, approve.  The Annual Salary and the Additional Compensation shall
be payable in accordance with the applicable payroll and/or other compensation
policies and plans of the Company or Spire, as applicable, as from time to time
in effect, less such deductions as shall be required to be withheld by
applicable law and regulations.  In consideration of the Employee agreeing to
the terms of Article 4 hereof, the parties agree that the Employee shall be
entitled to receive his full Annual Salary for the remainder of the Term if,
during the Term, his employment with Spire is terminated by Spire or the
Company other than pursuant to Article 6 hereof; provided, however, that if
the Employee's employment with Spire is terminated by the Employee or for any
reason beyond the control of Spire or the Company, neither the Company nor
Spire shall have any obligation to pay to the Employee any compensation or other
remuneration for any period subsequent to the date of such termination.

          3.2  MID-TERM TERMINATION.  If (i) the Employee's employment with
Spire is terminated by Spire prior to the first anniversary of the Commencement
date, other than pursuant to Section 6.2 hereof, (ii) the Employee is not in
breach of any of the representations, warranties, covenants or obligations set
forth in Articles 4 and 5 hereof, and (iii) the termination of the Employee's
employment occurs other than at the conclusion of a calendar year during the
Term, Spire shall pay to the Employee, within sixty (60) days from the
Employee's termination date, a portion of the Additional Compensation as
determined by the Board of Directors in its discretion.  Except as set forth in
this Section 3.2, upon the termination of the Employee's employment prior to
the completion of any calendar year during the Term, the Employee shall not be
entitled to any portion of the Additional Compensation for such year.

          3.3  PARTICIPATION IN EMPLOYEE BENEFIT PLANS.  The Employee shall be
permitted, during the Term, if and to the extent eligible, to participate in
any group life, hospitalization or disability insurance plan, health program,
pension plan, similar benefit plan or other "fringe benefits" of Spire which
may be available to all other employees of Spire generally on the same terms as
such other employees.

          3.4  EXECUTIVE SUPPORT.  Spire shall provide to the Employee office
facilities, furniture, fixtures and equipment, secretarial and support
personnel and other executive support services as reasonably necessary for the
Employee to perform his obligations under this Agreement.

          3.5  REIMBURSEMENT OF BUSINESS EXPENSES.  The Employee may incur
reasonable, ordinary and necessary business expenses in the course of
performing his obligations under this Agreement, including expenses for travel,
food, lodging and entertainment.  Spire shall reimburse the Employee for all
such business expenses if (i) such expenses are incurred by the Employee in
accordance with Spire's business expense reimbursement policy, if any, as may
be established and modified by Spire from time to time and (ii) the Employee
provides to Spire a record of (A) the amount of the expense, (B) the date,
place and nature of the expense, (C) the business reason for the expense and
(D) the names, occupations and other data concerning individuals entertained
sufficient to establish their business relationship to Spire.  Spire shall have
no obligation to reimburse the Employee for expenses that are not incurred and
substantiated as required pursuant to this Section 3.5.

          3.6  RESTRICTIONS ON TRANSFER. The Shares will not be registered
under the Securities Act of 1933, as amended (the "Securities Act"), and may
not be sold, transferred, or otherwise disposed of for value unless they are
subsequently registered under the Securities Act or an exemptioned to and
reasonably satisfactory to the Company.  The certificates, if any, evidencing
the Shares shall be stamped or otherwise imprinted with a legend substantially
in the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "SECURITIES ACT"), AND ARE "RESTRICTED SECURITIES" WITHIN THE
          MEANING OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT ( RULE
          144").  THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND
          MAY NOT BE SOLD OR TRANSFERRED WITHOUT COMPLYING WITH RULE 144
          IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT OR OTHER
          COMPLIANCE UNDER THE SECURITIES ACT. THE SECURITIES ARE SUBJECT
          TO ADDITIONAL RESTRICTIONS AS SET FORTH IN THAT CERTAIN
          EMPLOYMENT AGREEMENT, DATED DECEMBER 31, 1997, BETWEEN SENTO
          TECHNICAL INNOVATIONS CORPORATION, A UTAH CORPORATION AND JAY
          BARTH.

Nothing herein shall create any obligation on the part of the Company, Spire or
any of their respective directors, officers or employees to cause the Shares to
be registered under the Securities Act.

     4.   NON-COMPETITION.

          4.1  COVENANTS AGAINST COMPETITION.  The Employee acknowledges that

as follows:

               4.1.1     NON-COMPETE.  For a period commencing on the
Commencement Date hereof and terminating on the second anniversary of the
termination of this Agreement (the "Restricted Period"), the Employee shall

the Business for the Employee's own account in competition with the Company;
(ii) enter the employ of, or render any services to, any person engaged in
competition with the Company; or (iii) become interested in any such person in
any capacity, including, without limitation, as an individual, partner, member,
manager, shareholder, officer, director, principal, agent or trustee; provided,
however, that the Employee may own, directly or indirectly, solely as an
investment, securities of any person traded on any national securities exchange
or over-the-counter market if the Employee is not an affiliate (as defined in
the Securities Act)  of such person and does not, directly or indirectly, own
five percent or more of any class of securities of such person.

               4.1.2     CONFIDENTIAL INFORMATION; PERSONAL RELATIONSHIPS.
During the Restricted Period and thereafter, the Employee shall keep secret and
retain in strict confidence, and shall not use for the benefit of himself or
others, all confidential matters of the Company including, without limitation,
"know-how," trade secrets, customer lists, details of client or consultant
contracts, pricing policies, operational methods, marketing plans or
strategies, product development techniques or plans, business acquisition
plans, new personnel acquisition plans, methods of production and distribution,

Restricted Period; nor may the Employee exploit for his own benefit, or the
benefit of others, personal relationships with customers, suppliers or agents
of the Company in connection with or adversely affecting the Business formed
heretofore or during the Restricted Period.

               4.1.3     PROPERTY OF THE COMPANY.  All memoranda, notes, lists,
records and other documents or papers (and all copies thereof), including such
items stored in computer memories, on microfiche or by any other means, made or
compiled by or on behalf of the Employee, or made available to the Employee
relating to the Company, other than purely personal matters, are and shall be
the property of the Company, and shall be delivered to the Company promptly
upon the termination of the Employee's employment (whether such termination is
for Cause or otherwise) or at any other time on request of the Company.

               4.1.4     EMPLOYEES OF COMPANY.  During the Restricted Period
and thereafter for as long as the Employee shall remain an employee of or

          4.2  RIGHTS AND REMEDIES UPON BREACH.  If the Employee breaches, or
threatens to commit a breach of, any of the provisions of Section 4.1 (the
"Restrictive Covenants"), the Company shall have the following rights and
remedies, each of which rights and remedies shall be independent of the others
and severally enforceable, and each of which is in addition to, and not in lieu
of, any other rights and remedies available to the Company under law or in
equity:

               4.2.1     SPECIFIC PERFORMANCE.  The right and remedy to have
the Restrictive Covenants specifically enforced by any court of competent
jurisdiction, it being agreed that any breach or threatened breach of the
Restrictive Covenants would cause irreparable injury to the Company and that
money damages would not provide an adequate remedy to the Company.

               4.2.2     ACCOUNTING.  The right and remedy to require the
Employee to account for and pay over to the Company all compensation, profits,
monies, accruals, increments or other benefits derived or received by the
Employee as the result of any transactions constituting a breach of the
Restrictive Covenants.

          4.3  SEVERABILITY OF COVENANTS.  The Employee acknowledges and agrees
that the Restrictive Covenants are reasonable and valid in geographical and
temporal scope and in all other respects.  If any court determines that any of
the Restrictive Covenants, or any part thereof, is invalid or unenforceable,
the remainder of the Restrictive Covenants shall not thereby be affected and
shall be given full effect, without regard to the invalid portions.

          4.4  BLUE-PENCILING.  If any court determines that any of the
Restrictive Covenants, or any part thereof, is unenforceable because of the
duration or geographic scope of such provision, such court shall have the power
to reduce the duration or scope of such provision, as the case may be, and, in
its reduced form, such provision shall then be enforceable.

          4.5  ENFORCEABILITY in Jurisdictions.  The Company and the Employee
intend to and hereby confer jurisdiction to enforce the Restrictive Covenants
upon the courts of any jurisdiction within the geographical scope of the
Restrictive Covenants.  If the courts of any one or more of such jurisdictions
hold the Restrictive Covenants unenforceable by reason of the breadth of such
scope or otherwise, it is the intention of the Company and the Employee that
such determination not bar or in any way affect the Company's right to the
relief provided above in the courts of any other jurisdiction within the
geographical scope of the Restrictive Covenants, as to breaches of such
covenants in such other respective jurisdictions, such covenants as they relate
to each jurisdiction being, for this purpose, severable into diverse and
independent covenants.

     5.   REPRESENTATIONS AND WARRANTIES.  In order to induce the Company to
enter into this Agreement and perform the Company's obligations contemplated
hereby, including, without limitation, the Company's obligation to issue the
Shares to the Employee pursuant to Section 3.1.2, the Employee hereby
acknowledges, represents, warrants and agrees that:

          5.1  The Company has previously made available for inspection by the
Employee financial statements and other financial, corporate and business
information and records with respect to the Company.

          5.2  The Employee may have to bear the economic risk of any
investment related to  the Shares for an indefinite period of time.

          5.3  No representations, promises or agreements have been made
concerning the marketability or value of the Shares or that any of the Shares
will be registered under the Securities Act or any state securities or blue sky
laws at any time in the future or will otherwise be qualified for sale under
the applicable securities laws.

          5.4  No representations, warranties, promises or agreements have been
made to the Employee with respect to any of the following:

               5.4.1     The approximate or exact length of time the Employee
will be required to remain an owner of the Shares;

               5.4.2     The percentage of profit and/or the amount or type of
consideration (including dividends), profit or loss (including tax write-offs
and/or tax benefits) to be realized, if any, as a result of an investment in
the Shares; and/or

               5.4.3     That the past performance or experience of the Company

results of the ownership of the Shares, or the likelihood of achievement of the
overall objectives of the Company.

          5.5  The Employee is able to bear the substantial economic risks of
an investment in the Company, including but not limited to the possibility of
the complete loss of the Employee's investment in the Shares, the lack of a
public market, and the limited transferability of the Shares which may make the
liquidation of this investment impossible for the indefinite future.  The
Employee has no need for liquidity in such investment, and could afford a
complete loss of such investment.  The Employee has reached the age of majority
and has adequate means of providing for the Employee's current needs and
personal contingencies.

business matters that the Employee is capable of evaluating the merits and
risks of the investment in the Company and of protecting his own interests.

          5.8  The Shares will be acquired for the Employee's own account for
investment and not with a view toward resale or distribution thereof, and the
Employee does not now have any reason to anticipate any change in the
Employee's circumstances or other particular occasion or event which would
cause the Employee to sell any of the Shares or any interest therein.

          5.9  The Employee has received and reviewed all business, corporate
and financial documents and records concerning the Company that the Employee
wishes to receive and review.

          5.10 The Employee has been given an opportunity to discuss the
history, business, corporate matters and prospects of the Company and the
management thereof with the officers and directors of the Company.  The
Employee is fully informed with respect to the merits and risks associated
with the Shares and with the history, management business, prospects and
corporate matters of the Company.

          5.11 Neither the Employee's execution and delivery of this Agreement
nor the performance of his obligations hereunder will (i) violate any
restriction of any government, governmental agency or court to which the
Employee is subject, (ii) conflict with, result in a breach of, constitute a
default under or require any notice under any agreement, arrangement or
contract to which Employee is a party or by which the Employee is bound or
(iii) be limited or restricted by any such agreement, arrangement or contract.

          5.12 All representations and warranties set forth above or in any
other written statement or document delivered by the Employee in connection
with the transactions contemplated hereby will be true and correct in all
respects on and as of the date of the sale of any of the Shares as if made on
and as of such date and will survive such sale and/or exercise.

          5.13 The Employee understands the meaning and legal consequences of
the representations and warranties contained in this Agreement and agrees to
indemnify and hold harmless the Company and its directors, officers, agents and
representatives from and against any and all loss, damage or liability due to
or arising out of a breach of or the inaccuracy of any representation or
warranty of the Employee in this Agreement. Notwithstanding any of the
representations, warranties, acknowledgments or arrangements made herein by the
Employee, the Employee does not hereby or in any manner waive any right granted
to the Employee under federal or state securities laws.

     6.   TERMINATION.

          6.1  TERMINATION UPON DEATH.  If the Employee dies during the Term,
this Agreement shall terminate, except that the Employee's legal
representatives, successors, heirs or assigns shall be entitled to receive the
Annual Salary, the Additional Compensation and other accrued benefits, if any,
earned up to the date of the Employee's death; provided, however, if any
Additional Compensation or other benefits are governed by the provisions of any
written employee benefit plan or policy of the Company or any of its
subsidiaries, any written agreement contemplated thereunder or any other
separate written agreement entered into between the Employee and the Company or
any of its subsidiaries, the terms and conditions of such plan, policy or
agreement shall control in the event of any discrepancy or conflict with the
provisions of this Agreement regarding such Additional Compensation or other
benefit upon the death, termination or disability of the Employee pursuant to
Article 6 hereof.

          6.2  TERMINATION FOR CAUSE.  The Company or Spire has the right, at
any time during the Term, subject to all of the provisions hereof, exercisable
by serving notice, effective in accordance with its terms, to terminate the
Employee's employment under this Agreement and discharge the Employee for
"Cause" (as hereinafter defined).  If such right is exercised, the total
obligation of the Company and Spire to the Employee shall be limited to the
payment of any unpaid Annual Salary, Additional Compensation (subject to the
provisions of Section 3.1.2 hereof) and other benefits, if any, accrued up to
the effective date (which shall not be retroactive) specified in the notice of
termination delivered by the Company or Spire.  As used in this Section 6.2,
the term "Cause" shall mean and include (i) a material breach by the Employee
of the terms of this Agreement, (ii) wrongful misappropriation of any money or
other assets or properties of the Company or any subsidiary or affiliate of the
Company, (iii) the conviction of the Employee for any felony or other serious
crime, (iv) chronic alcoholism or drug addiction, or (v) the Employee's gross
moral turpitude relevant to his office or employment with the Company or any
subsidiary or affiliate of the Company.

          6.3  SUSPENSION UPON DISABILITY.  If during the Term the Employee
becomes physically or mentally disabled, whether totally or partially, as
evidenced by the written statement of two competent physicians licensed to
practice medicine in the United States, so that the Employee is unable to
substantially perform his services hereunder for (i) a period of six
consecutive months, or (ii) for shorter periods aggregating six months during
any twelve-month period, Spire may at any time after the last day of the six
consecutive months of disability or the day on which the shorter periods of
disability equal an aggregate of six months, by written notice to the Employee,
suspend the Term of the Employee's employment hereunder and discontinue
payments of the Annual Salary, Additional Compensation and other benefits.  If
at any time the Employee shall no longer be disabled, as evidenced by the
written statement of a competent physician licensed to practice medicine in the
United Sates, Spire may at its election fully reinstate, and if such disability
was for a period of not more than twelve consecutive months Spire shall fully
reinstate the employment of the Employee pursuant to this Agreement and shall
commence payment of the Annual Salary and all of the terms of this Agreement
shall resume in full force for the balance of the Term.  Nothing in this
Section 6.3 shall be deemed to extend the Term.

     7.   INSURANCE.  The Company or Spire may, from time to time, apply for
and take out, in its own name and at its own expense, naming itself or others
as the designated beneficiary (which it may change from time to time), policies
for health, accident, disability or other insurance upon the Employee in any
amount or amounts that it may deem necessary or appropriate to protect its
interest.  The Employee agrees to aid the Company an/or Spire in procuring such
insurance by submitting to reasonable medical examinations and by filling out,
executing and delivering such applications and other instruments in writing as
may reasonably be required by an insurance company or companies to which any
application or applications for insurance may be made by or for the Company or
Spire.

Employee Forty Thousand and No/100 Dollars ($40,000) in cash and issue to the
Employee Twenty-Five Thousand (25,000) shares of the common stock, par value
$.25, of the Company (the "Shares" and collectively with such cash, the
"Signing Bonus").

The Employee shall also be eligible, during the Term, to receive such other
compensation, whether in the form of cash bonuses, stock options, stock
appreciation rights, restricted stock awards or otherwise, (collectively, with
the Signing Bonus, the "Additional Compensation"), as the Boards of Directors
of the Company and/or Spire (or any committee thereof) may, at their
discretion, approve.  The Annual Salary and the Additional Compensation shall
be payable in accordance with the applicable payroll and/or other compensation
policies and plans of the Company or Spire, as applicable, as from time to time
in effect, less such deductions as shall be required to be withheld by
applicable law and regulations.  In consideration of the Employee agreeing to
the terms of Article 4 hereof, the parties agree that the Employee shall be
entitled to receive his full Annual Salary for the remainder of the Term if,
during the Term, his employment with Spire is terminated by Spire or the
Company other than pursuant to Article 6 hereof; provided, however, that if the
Employee's employment with Spire is terminated by the Employee or for any
reason beyond the control of Spire or the Company, neither the Company nor
Spire shall have any obligation to pay to the Employee any compensation or
other remuneration for any period subsequent to the date of such termination.

          3.2  MID-TERM TERMINATION.  If (i) the Employee's employment with
Spire is terminated by Spire prior to the first anniversary of the Commencement
date, other than pursuant to Section 6.2 hereof, (ii) the Employee is not in
breach of any of the representations, warranties, covenants or obligations set
forth in Articles 4 and 5 hereof, and (iii) the termination of the Employee's
employment occurs other than at the conclusion of a calendar year during the
Term, Spire shall pay to the Employee, within sixty (60) days from the
Employee's termination date, a portion of the Additional Compensation as
determined by the Board of Directors in its discretion.  Except as set forth in
this Section 3.2, upon the termination of the Employee's employment prior to
the completion of any calendar year during the Term, the Employee shall not be
entitled to any portion of the Additional Compensation for such year.

          3.3  PARTICIPATION IN EMPLOYEE BENEFIT PLANS.  The Employee shall be
permitted, during the Term, if and to the extent eligible, to participate in
any group life, hospitalization or disability insurance plan, health program,
pension plan, similar benefit plan or other "fringe benefits" of Spire which
may be available to all other employees of Spire generally on the same terms as
such other employees.

          3.4  EXECUTIVE SUPPORT.  Spire shall provide to the Employee office
facilities, furniture, fixtures and equipment, secretarial and support
personnel and other executive support services as reasonably necessary for the
Employee to perform his obligations under this Agreement.

          3.5  REIMBURSEMENT OF BUSINESS EXPENSES.  The Employee may incur
reasonable, ordinary and necessary business expenses in the course of
performing his obligations under this Agreement, including expenses for travel,
food, lodging and entertainment.  Spire shall reimburse the Employee for all
such business expenses if (i) such expenses are incurred by the Employee in
accordance with Spire's business expense reimbursement policy, if any, as may
be established and modified by Spire from time to time and (ii) the Employee
provides to Spire a record of (A) the amount of the expense, (B) the date, place
and nature of the expense, (C) the business reason for the expense and (D) the
names, occupations and other data concerning individuals entertained sufficient
to establish their business relationship to Spire.  Spire shall have no
obligation to reimburse the Employee for expenses that are not incurred and
substantiated as required pursuant to this Section 3.5.

          3.6  RESTRICTIONS ON TRANSFER. The Shares will not be registered
under the Securities Act of 1933, as amended (the "Securities Act"), and may
not be sold, transferred, or otherwise disposed of for value unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available, as evidenced by an opinion of counsel retained by
the Employee and addressed to and reasonably satisfactory to the Company.  The
certificates, if any, evidencing the Shares shall be stamped or otherwise
imprinted with a legend substantially in the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "SECURITIES ACT"), AND ARE "RESTRICTED SECURITIES" WITHIN THE
          MEANING OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT ( RULE

          MAY NOT BE SOLD OR TRANSFERRED WITHOUT COMPLYING WITH RULE 144
          IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT OR OTHER
          COMPLIANCE UNDER THE SECURITIES ACT. THE SECURITIES ARE SUBJECT
          TO ADDITIONAL RESTRICTIONS AS SET FORTH IN THAT CERTAIN
          EMPLOYMENT AGREEMENT, DATED DECEMBER 31, 1997, BETWEEN SENTO
          TECHNICAL INNOVATIONS CORPORATION, A UTAH CORPORATION AND JOSEPH

               4.1.2     CONFIDENTIAL INFORMATION; PERSONAL RELATIONSHIPS.
During the Restricted Period and thereafter, the Employee shall keep secret and

the property of the Company, and shall be delivered to the Company promptly

for Cause or otherwise) or at any other time on request of the Company.

               4.1.4     EMPLOYEES OF COMPANY.  During the Restricted Period

and severally enforceable, and each of which is in addition to, and not in lieu
of, any other rights and remedies available to the Company under law or in
equity:

               4.2.1     SPECIFIC PERFORMANCE.  The right and remedy to have
the Restrictive Covenants specifically enforced by any court of competent
jurisdiction, it being agreed that any breach or threatened breach of the
Restrictive Covenants would cause irreparable injury to the Company and that
money damages would not provide an adequate remedy to the Company.

               4.2.2     ACCOUNTING.  The right and remedy to require the
Employee to account for and pay over to the Company all compensation, profits,
monies, accruals, increments or other benefits derived or received by the

Restrictive Covenants.
          4.3  SEVERABILITY OF COVENANTS.  The Employee acknowledges and agrees
that the Restrictive Covenants are reasonable and valid in geographical and
temporal scope and in all other respects.  If any court determines that any of
the Restrictive Covenants, or any part thereof, is invalid or unenforceable,
the remainder of the Restrictive Covenants shall not thereby be affected and
shall be given full effect, without regard to the invalid portions.

          4.4  BLUE-PENCILING.  If any court determines that any of the
Restrictive Covenants, or any part thereof, is unenforceable because of the
duration or geographic scope of such provision, such court shall have the power
to reduce the duration or scope of such provision, as the case may be, and, in
its reduced form, such provision shall then be enforceable.

          4.5  ENFORCEABILITY IN JURISDICTIONS.  The Company and the Employee
intend to and hereby confer jurisdiction to enforce the Restrictive Covenants
upon the courts of any jurisdiction within the geographical scope of the
Restrictive Covenants.  If the courts of any one or more of such jurisdictions
hold the Restrictive Covenants unenforceable by reason of the breadth of such
scope or otherwise, it is the intention of the Company and the Employee that
such determination not bar or in any way affect the Company's right to the
relief provided above in the courts of any other jurisdiction within the
geographical scope of the Restrictive Covenants, as to breaches of such
covenants in such other respective jurisdictions, such covenants as they relate
to each jurisdiction being, for this purpose, severable into diverse and
independent covenants.

          v.        Representations and Warranties.  In order to induce the
               Company to enter into this Agreement and perform the Company's
               obligations contemplated hereby, including, without limitation,
               the Company's obligation to issue the Shares to the Employee
               pursuant to Section 3.1.2, the Employee hereby acknowledges,
               represents, warrants and agrees that:

          5.1  The Company has previously made available for inspection by the
Employee financial statements and other financial, corporate and business
information and records with respect to the Company.

          5.2  The Employee may have to bear the economic risk of any
investment related to  the Shares for an indefinite period of time.

          5.3  No representations, promises or agreements have been made
concerning the marketability or value of the Shares or that any of the Shares

laws at any time in the future or will otherwise be qualified for sale under
the applicable securities laws.

          5.4  No representations, warranties, promises or agreements have been
made to the Employee with respect to any of the following:

               5.4.1     The approximate or exact length of time the Employee

consideration (including dividends), profit or loss (including tax write-offs
and/or tax benefits) to be realized, if any, as a result of an investment in
the Shares; and/or

               5.4.3     That the past performance or experience of the Company
will in any way indicate the results of future operations of the Company, the
results of the ownership of the Shares, or the likelihood of achievement of the
overall objectives of the Company.

          5.5  The Employee is able to bear the substantial economic risks of
an investment in the Company, including but not limited to the possibility of
the complete loss of the Employee's investment in the Shares, the lack of a
public market, and the limited transferability of the Shares which may make the
liquidation of this investment impossible for the indefinite future.  The
Employee has no need for liquidity in such investment, and could afford a
complete loss of such investment.  The Employee has reached the age of majority
and has adequate means of providing for the Employee's current needs and
personal contingencies.

          5.6  [Omitted]

          5.7  The Employee has such knowledge and experience in financial and
business matters that the Employee is capable of evaluating the merits and
risks of the investment in the Company and of protecting his own interests.

          5.8  The Shares will be acquired for the Employee's own account for
investment and not with a view toward resale or distribution thereof, and the
Employee does not now have any reason to anticipate any change in the
Employee's circumstances or other particular occasion or event which would
cause the Employee to sell any of the Shares or any interest therein.

          5.9  The Employee has received and reviewed all business, corporate
and financial documents and records concerning the Company that the Employee
wishes to receive and review.

          5.10 The Employee has been given an opportunity to discuss the

management thereof with the officers and directors of the Company.  The
Employee is fully informed with respect to the merits and risks associated
with the Shares and with the history, management business, prospects and
corporate matters of the Company.

          5.11 Neither the Employee's execution and delivery of this Agreement
nor the performance of his obligations hereunder will (i) violate any
restriction of any government, governmental agency or court to which the
Employee is subject, (ii) conflict with, result in a breach of, constitute a
default under or require any notice under any agreement, arrangement or
contract to which Employee is a party or by which the Employee is bound or
(iii) be limited or restricted by any such agreement, arrangement or contract.

          5.12 All representations and warranties set forth above or in any
other written statement or document delivered by the Employee in connection
with the transactions contemplated hereby will be true and correct in all
respects on and as of the date of the sale of any of the Shares as if made on
and as of such date and will survive such sale and/or exercise.

          5.13 The Employee understands the meaning and legal consequences of
the representations and warranties contained in this Agreement and agrees to
indemnify and hold harmless the Company and its directors, officers, agents and
representatives from and against any and all loss, damage or liability due to
or arising out of a breach of or the inaccuracy of any representation or
warranty of the Employee in this Agreement. Notwithstanding any of the
representations, warranties, acknowledgments or arrangements made herein by the
Employee, the Employee does not hereby or in any manner waive any right granted
to the Employee under federal or state securities laws.

          vi.       TERMINATION.

          6.1  TERMINATION UPON DEATH.  If the Employee dies during the Term,
this Agreement shall terminate, except that the Employee's legal
representatives, successors, heirs or assigns shall be entitled to receive the
Annual Salary, the Additional Compensation and other accrued benefits, if any,
earned up to the date of the Employee's death; provided, however, if any
Additional Compensation or other benefits are governed by the provisions of any
written employee benefit plan or policy of the Company or any of its
subsidiaries, any written agreement contemplated thereunder or any other
separate written agreement entered into between the Employee and the Company or
any of its subsidiaries, the terms and conditions of such plan, policy or
agreement shall control in the event of any discrepancy or conflict with the
provisions of this Agreement regarding such Additional Compensation or other
benefit upon the death, termination or disability of the Employee pursuant to
Article 6 hereof.
          6.2  TERMINATION FOR CAUSE.  The Company or Spire has the right, at
any time during the Term, subject to all of the provisions hereof, exercisable
by serving notice, effective in accordance with its terms, to terminate the
Employee's employment under this Agreement and discharge the Employee for
"Cause" (as hereinafter defined).  If such right is exercised, the total
obligation of the Company and Spire to the Employee shall be limited to the
payment of any unpaid Annual Salary, Additional Compensation and other
benefits, if any, accrued up to the effective date (which shall not be
retroactive) specified in the notice of termination delivered by the Company or
Spire.  As used in this Section 6.2, the term "Cause" shall mean and include
(i) a material breach by the Employee of the terms of this Agreement, (ii)
wrongful misappropriation of any money or other assets or properties of the
Company or any subsidiary or affiliate of the Company, (iii) the conviction of
the Employee for any felony or other serious crime, (iv) chronic alcoholism or
drug addiction, or (v) the Employee's gross moral turpitude relevant to his
office or employment with the Company or any subsidiary or affiliate of the
Company.

          6.3  SUSPENSION UPON DISABILITY.  If during the Term the Employee
becomes physically or mentally disabled, whether totally or partially, as
evidenced by the written statement of two competent physicians licensed to
practice medicine in the United States, so that the Employee is unable to
substantially perform his services hereunder for (i) a period of six
consecutive months, or (ii) for shorter periods aggregating six months during
any twelve-month period, Spire may at any time after the last day of the six
consecutive months of disability or the day on which the shorter periods of
disability equal an aggregate of six months, by written notice to the Employee,
suspend the Term of the Employee's employment hereunder and discontinue
payments of the Annual Salary, Additional Compensation and other benefits.  If
at any time the Employee shall no longer be disabled, as evidenced by the
written statement of a competent physician licensed to practice medicine in the
United Sates, Spire may at its election fully reinstate, and if such disability
was for a period of not more than twelve consecutive months Spire shall fully
reinstate the employment of the Employee pursuant to this Agreement and shall
commence payment of the Annual Salary and all of the terms of this Agreement
shall resume in full force for the balance of the Term.  Nothing in this
Section 6.3 shall be deemed to extend the Term.

          vii.      INSURANCE.  The Company or Spire may, from time to time,
               apply for and take out, in its own name and at its own expense,
               naming itself or others as the designated beneficiary (which it
               may change from time to time), policies for health, accident,
               disability or other insurance upon the Employee in any amount or
               amounts that it may deem necessary or appropriate to protect its
               interest.  The Employee agrees to aid the Company an/or Spire in
               procuring such insurance by submitting to reasonable medical
               examinations and by filling out, executing and delivering such
               applications and other instruments in writing as may reasonably
               be required by an insurance company or companies to which any
               application or applications for insurance may be made by or for
               the Company or Spire.

          viii.          OTHER PROVISIONS.

          8.1  NOTICES.  Any notice or other communication required or
permitted hereunder shall be in writing and shall be delivered personally,
telegraphed, telexed, sent by facsimile transmission or sent by certified,

Orem, Utah, January 6, 1998     Sento Technical Innovations Corporation (NASDAQ
Symbol: SNTO) announced today that it has restructured and finalized its
acquisition of Astron Incorporated.  Astron is a provider of computer training
and education courses delivered nationwide to such organizations as Intel,
American Airlines, IBM, AT&T, U.S. Navy, Microsoft, and General Motors.
Astron's courses include Microsoft MCSE (Microsoft Certified System Engineer)
for Windows NT, Novell CNE (Certified Novell Engineer), and Citrix CWA
(Certified WinFrame Administrator) certification training courses.

The revised structure and terms of the acquisition were agreed to by Sento and
Astron following completion of a financial audit of Astron.  The restructured
acquisition consisted of a merger of Sento Acquisition, Inc., a wholly-owned
subsidiary of Sento, with and into Astron, with Jay Barth, the sole
shareholder, founder and President of Astron, receiving 180,000 shares of Sento
Common Stock in exchange for his ownership of all of the shares of capital
stock of Astron.  As a result of the transaction, Astron became a wholly-owned
subsidiary of Sento.  In addition, Sento agreed to employ Mr. Barth as Director
of Training and Education of Spire Technologies, Inc., another wholly-owned
subsidiary of Sento.

"We are very excited to have completed this acquisition," said Kieth Sorenson,
CEO of Sento.  "Astron provides us with a critical set of tools as we continue
to expand into the growing computer systems education and services industry.
Astron's national reputation for premiere training and education programs is an
excellent complement to our existing solutions offerings."

"I believe that combining Astron with Sento's other product and service
offerings allows us to maximize our opportunity to provide service and support
to our customer base," said Jay Barth.  "We can now bring to our customers a
complete solutions set, from systems design and implementation, to product
licensing and integration, to training, education, and support services.  It's
an exciting opportunity for both Sento and Astron."

organizations of all sizes using Windows NT, UNIX, and OpenVMS client-server
computing environments.  These services include Network Consulting, Systems
