                                   AXCESS INC.

                    NON-VOTING COMMON STOCK PURCHASE WARRANT

The following recitals are true and constitute the basis for this Warrant:

A.   This Warrant represents the first in a series of up to three separate
     Warrants to be issued to Amphion Ventures, L.P., a Delaware limited
     partnership, or its successors in interest, assigns or transferees
     (collectively, the "Warrant Holder"), in consideration for it making
     advances to AXCESS Inc., a Delaware corporation (the "Company") pursuant to
     the terms of that certain Convertible Note of even date herewith executed
     by the Company payable to the Warrant Holder in the stated principal amount
     of up to $6,000,000 (the "Note");

B.   The total number of shares of the Company's Non-Voting Common Stock (as
     defined in Section 9(a) hereof) (the "Warrant Shares") to be issued to the
     Warrant Holder in consideration of its advances to the Company under the
     Note shall be based upon ten percent (10%) of the outstanding principal
     balance of the Note on the date hereof and on each of the first two
     anniversary dates of the Note. Each Warrant shall be in the form hereof,
     with the exception that the Warrant Shares to be granted upon the exercise
     of each such Warrant shall be exercisable at any time and from time to time
     on or prior to the date which is five years from the date of issuance of
     each such Warrant; and

C.   The number of Warrant Shares to be issued on the date hereof and on each of
     the first two anniversary dates of the Note shall be determined by dividing
     ten percent (10%) of the principal balance of the Note on each applicable
     date by $2.10. The aggregate number of Warrant Shares to be issued under
     the series of Warrants shall not, however, exceed 857,143 Warrant Shares
     (subject to the antidilution provisions of the Warrants).

     THIS CERTIFIES THAT, for value received, the Warrant Holder is entitled to
purchase from the Company, 180,362 Warrant Shares at the exercise price of Two
Dollars and Ten Cents ($2.10) per share (the "Exercise Price"). The number of
Warrant Shares and the Exercise Price shall be adjusted and readjusted or
changed from time to time in accordance with Section 4 hereof.

     This Warrant may be exercised at any time and from time to time on or prior
to September 30, 2004.

     SECTION 1. EXERCISE OF WARRANT.

     The rights represented by this Warrant may be exercised by the Warrant
Holder, in whole or in part, by (a) delivering to the Company a duly executed
notice of exercise in the form of Annex A hereto and (b) at the Warrant Holder's
option, either (i) delivering a check payable to (or wire transfer to the
account of) the Company in an amount equal to the product of (x) the Exercise
Price times (y) the number of Warrant Shares as to which this Warrant is being
exercised (such product, the "Total Exercise Price") or (ii) delivering to the
Company a letter (the "Conversion Letter") requesting conversion or exchange of
a portion of any indebtedness owed by the Company to the Warrant Holder in an
amount equal to the Total Exercise Price or (iii) surrendering to the Company a
portion of this Warrant with a "Value" (as defined below) equal to the Total
Exercise Price. For the purpose of clause (b) (iii) above, "Value" shall mean
the product of (I) the amount by which the average closing price per share of
the Company's Common Stock over the ten trading days preceding the date of
exercise, as reported in The Wall Street Journal, exceeds the Exercise Price and
(II) the number of Warrant Shares as to which this Warrant is surrendered for
the purpose of effecting payment for Warrant Shares. This Warrant shall be
deemed to have been exercised immediately prior to the close of business on the
date of delivery of a duly executed notice of exercise together with the amount
(in cash or by delivering the Conversion Letter or by surrender of a portion of
this Warrant) payable upon exercise of this Warrant and, as of such moment, (i)
the rights of the Warrant Holder, as such, with respect to the number of Warrant
Shares as to which this Warrant is being exercised (and, if applicable,
surrendered as payment of the Total Exercise Price) shall cease, and (ii) such
Warrant Holder shall be deemed to be the record holder of the shares of
Non-Voting Common Stock issuable upon such exercise. As soon as practicable
after the exercise, in whole or in part, of this Warrant, and in any event
within 5 business days thereafter, the Company at its expense (including the
payment by it of any applicable issuance or stamp taxes) will cause to be issued
in the name of and delivered to the Warrant Holder, or as the Warrant Holder
(upon payment by the Warrant Holder of any applicable transfer taxes) may
direct, a certificate or certificates for the number of fully paid and
nonassessable shares of Non-Voting Common Stock to which the Warrant Holder
shall be entitled upon such exercise. In the event of partial exercise of this
Warrant and, if applicable, partial surrender of this Warrant pursuant to clause
(b)(iii) of this Section, the Warrant need not be delivered to the Company;
provided that the Warrant Holder agrees to make a notation of such partial
exercise and, if applicable, surrender on the Warrant. If this Warrant is
delivered to the Company, the Company shall issue and deliver to the Warrant
Holder a new Warrant evidencing the rights to purchase the remaining Warrant
Shares, which new Warrant shall in all other respects be identical to this
Warrant.

                                       -2-

     Notwithstanding the foregoing or any other term or provision of this
Warrant, the Warrant Holder shall not be permitted, without the prior written
consent of the Company, to exercise its rights to acquire Warrant Shares
hereunder until such time as the Company shall have received the authorization
of its stockholders to issue Warrant Shares to the Warrant Holder upon the
exercise of all or any portion of this Warrant by the Warrant Holder. The
Company hereby agrees to submit such a proposal to its stockholders for approval
at the Company's 2000 annual meeting of stockholders and to use its best efforts
to obtain such approval.

     SECTION 2. INVESTMENT REPRESENTATION.

     By accepting this Warrant, the Warrant Holder represents that the Warrant
Holder is acquiring this Warrant for investment purposes and will not sell or
otherwise dispose of this Warrant or the underlying Warrant Shares in violation
of applicable securities laws. The Warrant Holder acknowledges that the
certificates representing any Warrant Shares will bear a legend indicating that
they have not been registered under the Act, and may not be sold by the Warrant
Holder except pursuant to an effective registration statement or pursuant to an
exemption from registration.

     SECTION 3. VALIDITY OF WARRANT AND ISSUE OF SHARES.

     The Company represents and warrants that this Warrant has been duly
authorized and validly issued and covenants and agrees that all shares of
Non-Voting Common Stock that may be issued upon the exercise of the rights
represented by this Warrant will, when issued upon such exercise, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges with respect to the issue thereof. The Company further
covenants and agrees that during the period within which the rights represented
by this Warrant may be exercised, the Company will at all times have authorized
and reserved a sufficient number of shares of Non-Voting Common Stock to provide
for the exercise of the rights represented by this Warrant.

     SECTION 4. ANTIDILUTION PROVISIONS.

     The terms of this Warrant shall be subject to adjustment as follows:

     (a) If the Company shall (i) pay a stock dividend or make a distribution to
holders of Non- Voting Common Stock or common stock in shares of its Non-Voting
Common Stock or common stock, as the case may be, (ii) subdivide its outstanding
shares of Non-Voting Common Stock or common stock, (iii) combine its outstanding
shares of Non-Voting Common Stock or common stock into a smaller number of
shares, or (iv) issue by reclassification of its shares of Non-Voting Common
Stock or common stock any shares of capital stock of the Company, (A) the
Exercise Price shall be increased or decreased as the case may be, to an amount
which shall bear the same relation to the Exercise Price in effect immediately
prior to such action as the total number of shares outstanding immediately prior
to such action shall bear to the total number of shares outstanding immediately
after such action and (B) this Warrant automatically shall be adjusted so that
it shall thereafter evidence the right to purchase the kind and number of
Warrant Shares or other securities which the Warrant Holder would have owned and
would have been entitled to receive after such action if this Warrant had been
exercised immediately prior to such action or any record date with respect
thereto. An adjustment made pursuant to this subsection shall become effective

                                       -3-
<PAGE>   4

retroactively immediately after the record date in the case of a dividend or
distribution of Non-Voting Common Stock or common stock and shall become
effective immediately after the effective date in the case of a subdivision,
combination or reclassification.

     (b) If the Company shall fix a record date for the making of a distribution
to all holders of Non-Voting Common Stock or its common stock (including any
such distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of (i) assets (other than cash dividends
or cash distributions payable out of consolidated net income or retained
earnings or dividends payable in Non-Voting Common Stock or common stock), (ii)
evidences of indebtedness or other debt or equity securities of the Company, or
of any corporation other than the Company (except for the Non-Voting Common
Stock or common stock of the Company) or (iii) subscription rights, options or
warrants to purchase any of the foregoing assets or securities, whether or not
such rights, options or warrants are immediately exercisable (hereinafter
collectively called "Distributions on Common Stock"), the Company shall make
provisions for the Warrant Holder to receive upon exercise of this Warrant, a
proportional amount (depending upon the extent to which this Warrant is
exercised) of such assets, evidences of indebtedness, securities or such other
rights, as if such Warrant Holder had exercised this Warrant on or before such
record date.

     (c) In the case of any consolidation or merger of the Company with or into
another corporation or the sale of all or substantially all the assets of the
Company to another person or entity, this Warrant thereafter shall be
exercisable for the kind and amount of shares of stock or other securities or
property to which a holder of the number of shares of Non-Voting Common Stock of
the Company deliverable upon exercise of this Warrant would have been entitled
upon such consolidation, merger or sale; and, in such case, appropriate
adjustment shall be made in the application of the provisions in this Section 4,
to the end that the provisions set forth in this Section 4 (including provisions
with respect to changes in and adjustments of the exercise price) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other securities or property thereafter deliverable upon the
exercise of this Warrant.

     (d) Upon the occurrence of each adjustment or readjustment of the exercise
price or any change in the number of Warrant Shares or in the shares of stock or
other securities or property deliverable upon exercise of this Warrant pursuant
to this Section 4, the Company at its expense shall promptly compute such
adjustment or readjustment and change in accordance with the terms hereof and
furnish to each holder hereof a certificate signed by the Chief Financial
Officer of the Company, setting forth such adjustment or readjustment and change
and showing in detail the facts upon which such adjustment or readjustment and
change is based. The Company shall, upon the written request at any time of the
Warrant Holder, furnish or cause to be furnished to such Holder, a similar
certificate setting forth (i) such adjustment or readjustment and change, (ii)
the Exercise Price then in effect, and (iii) the number of Warrant Shares and
the amount, if any, of other shares of stock and other securities and property
which would be received upon the exercise of the Warrant.

     (e) The Company shall not be required upon the exercise of this Warrant to
issue any fraction of shares, but shall make any adjustment therefor by rounding
the number of shares obtainable upon exercise to the next highest whole number
of shares.

                              EMPLOYMENT AGREEMENT

         This Agreement is made and entered into this 16th day of July, 1999, by
and between AXCESS Inc. ("Company") and Allen Griebenow ("Employee").

         The following recitals are true and constitute the basis for this
Agreement:

         A.       Pursuant to the terms of that certain Asset Purchase Agreement
                  dated July 15, 999, by and between the Company and Prism
                  Video, Inc. (the "Asset Purchase Agreement"), the Company
                  acquired substantially all of the assets previously used by
                  Prism Video, Inc. in connection with the operation of its
                  video products business;

         B.       Employee possesses significant knowledge and information in
                  matters related to the operation of the video products
                  business, which knowledge and information will be increased,
                  developed and enhanced through his employment by the Company;
                  and

         C.       Without the Employee's agreement to enter into this Agreement
                  with the Company, the Company would not have entered into the
                  Asset Purchase Agreement or agreed to consummate the
                  transactions contemplated thereby.

         NOW THEREFORE, in consideration of employment and other good and
valuable consideration, which is acknowledged to be sufficient, the parties
agree as follows:

         1. TERM. Employee's employment with the Company is "at-will" and this
Agreement may be terminated at any time by either the Employee or the Company.
If this Agreement is terminated by Employee for any reason, Employee shall give
the Company written notice of such termination at least thirty (30) days prior
to the effective termination date.

         2. POSITION AND RESPONSIBILITIES. The Company hereby agrees to employ
the Employee as its President and Chief Executive Officer. The Employee shall
have such responsibilities and authority as is customary for such position and
may from time to time be assigned to the Employee by the Board of Directors of
the Company.

         3. COMPENSATION. As compensation for all services to be performed by
the Employee under this Agreement, the Company shall compensate the Employee as
follows:

               A. SALARY. The Company shall pay to Employee a salary equal to
$17,917 per month, payable monthly in arrears in accordance with the customary
payroll policies of the Company in effect at the time such payment is made or as
the Company and the Employee may otherwise mutually agree. Subject to Employee
meeting the performance objectives assigned to him by the Chairman of the Board
during each fiscal year in which he is employed by the Company, Employee will be
eligible to receive a bonus payable within ninety (90) days after the end of the
Company's fiscal year of up to thirty percent (30%) of his base salary.
Employee's bonus, if any, will be

                                        1

<PAGE>   2

prorated based on the number of months during which he is employed by the
Company during each applicable fiscal year and will not be payable unless
Employee is employed as of the last day of the applicable fiscal year.

               B. BENEFITS AND PERQUISITES. Employee shall be entitled to (a)
paid vacation during each year of employment by the Company in accordance with
the policies of the Company in effect from time to time, (b) options to acquire
450,000 shares of the Company's common stock pursuant to the terms of the
Company's Stock Option Plan and form of Stock Option Agreement and (c) share in
any employee benefits provided by the Company from time to time on the same
basis as similarly situated employees of the Company, so long as the Company
continues to provide or offer such benefits to such employees. The Company may
change or amend any of these benefits at any time.

               C. EXPENSES. The Company shall reimburse the Employee for all
business expenses properly incurred by the Employee in the performance of the
Employee's duties hereunder and in accordance with policies established from
time to time by the Company. All such payments will be subject to deductions as
from time to time may be required to be made pursuant to law, government
regulations or order, or by agreement with, or consent of, the Employee.

         4. A. DEATH. In the event of Employee's death, this Agreement shall
terminate immediately and Employee shall not be entitled to any additional
compensation.

         B. DISABILITY. If, as a result of Employee's incapacity due to physical
or mental illness, Employee shall have been absent from his duties with the
Company on a full-time basis for six (6) months and, within sixty (60) days
after written notice of termination is thereafter given by the Company, Employee
shall not have returned to the full-time performance of Employee's duties,
Company may terminate this Agreement for "Disability" and Employee shall not be
entitled to any additional compensation.

               C. TERMINATION WITHOUT CAUSE. If the Company terminates the
Employee's employment at any time without "Cause" (as defined below), the
Employee shall be entitled to continue to receive his then current salary for
the six (6) month period following Employee's effective termination date. The
obligations of the Company to the Employee under this Section 4C are conditioned
upon the Employee signing a release of claims in the form of Exhibit "A"
attached hereto (the "Release") within twenty-eight (28) days of the date on
which notice of termination is given and upon such Release remaining in full
force and effect thereafter. The severance payment under this Section 4C will be
in the form of salary continuation, payable in accordance with the normal
payroll practices of the Company and will begin at the Company's next regular
payroll period following the effective date of the Release, but shall be
retroactive to the Date of Termination. For purposes of this Agreement, "Cause"
shall mean Employee's engagement in any one of the following: (a) fraud,
misappropriation or embezzlement; (b) after his conviction by a court of
competent jurisdiction of a felony; or (c) after repeated incompetence,
insubordination, dishonesty, other acts detrimental to the interest of the
Company or its affiliates, or any material breach by the Employee of this
Agreement, the Noncompetition, Nonsolicitation and Confidentiality Agreement of
even date herewith or the Company's policies and procedures.

                                        2

<PAGE>   3

         5. DATE OF TERMINATION. For purposes of Section 4 of this Agreement,
the "Date of Termination" shall mean the day the Employee is notified of his
termination by the Company or the date of Employee's resignation or death, as
the case may be.

         6. DISCOVERIES AND INVENTIONS. All inventions, discoveries and ideas
made or conceived by Employee or by Employee and other employees of the Company,
while employed by the Company, shall be owned exclusively by the Company.
Employee hereby agrees that Employee shall have no ownership interest in such
inventions, discoveries or ideas that shall have no claim against the Company
for any additional compensation for such inventions, discoveries or ideas.
Employee hereby agrees to immediately disclose the existence of any such
invention, discovery or idea to the Company. At the request of the Company and
at the Company's expense, either during or after the Term or any extension
thereof, the Employee shall cooperate fully with the Company to secure any
patent and or copyright on any such invention, discovery or idea and hereby
agrees to execute and deliver any and all documents and all documents and
instruments and perform any additional acts that may be necessary or appropriate
to perfect the Company's interest in any such invention, discovery or idea.

         7. SOLE AGREEMENT. The Employee hereby acknowledges the termination of
any and all employment or consulting agreements between him and the Company not
expressly set forth herein, and any affiliates of the Company, and releases the
Company and all affiliates of the Company from any and all obligations that it
or they might otherwise have had to Employee under any employment or consulting
agreement between the Company or any affiliates of the Company and Employee,
including, but not by way of limitation, any obligations of the Company or its
affiliates to pay Employee accrued but unpaid compensation of any sort
whatsoever.

         8. ASSIGNMENT. This Agreement may not be assigned or transferred by
Employee, in whole or in part, without the prior written consent of the Company,
and any assignment in violation of this Section shall be void. The Company shall
have the right to assign this Agreement and any of its rights hereunder to any
of its affiliates or as a part of a sale or transfer of the stock, assets or
business of the Company or any substantial portion thereof.

         9. INTERPRETATION; SEVERABILITY OF INVALID PROVISIONS. All rights and
restrictions contained hereunder may be exercised and shall be applicable and
binding only to the extent that they do not violate any applicable laws and are
intended to be limited to the extent necessary to render this Agreement legal,
valid and enforceable. If any term of this Agreement shall be held to be
illegal, invalid or unenforceable by a court of competent jurisdiction, the
remaining terms shall remain in full force and effect. The existence of any
claim by the Employee against the Company, whether predicated on this Agreement
or otherwise, shall not constitute a defense to enforcement by the Company of
any or all such provisions or covenants.

         10. RELIEF. The parties acknowledge that a breach or threatened breach
of any of the terms of this Agreement by the Employee would result in material
and irreparable damage and injury to the Company, and that it would be difficult
or impossible to establish the full monetary value of such damage. Therefore,
the Company shall be entitled to injunctive relief by a court of appropriate
jurisdiction in the event of Employee's breach or threatened breach of any of
the terms hereunder.

                                        3

<PAGE>   4

The Company's right to an injunction will not prohibit the Company from pursuing
other remedies, including the recovery of damages.

         11. AGREEMENT BINDING. This Agreement shall inure to the benefit of the
Company and its successors, assignees and designees and shall be binding upon
Employee and Employee's heirs, executors, administrators and personal
representatives.

         12. NONWAIVER. No failure on the part of either Employee or the Company
to exercise, and no delay by either Employee or the Company in exercising any
right, power, or remedy under this Agreement shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, power or remedy by either
Employee or the Company preclude any other or further exercise thereof or the
exercise by such party of any other right, power or remedy. No express waiver or
assent by either Employee or the Company of any breach of or default in any term
or condition of this Agreement by the other party shall constitute a waiver of
or assent to any succeeding breach of or default in the same or any other term
or condition hereof.

         13. AMENDMENTS AND MODIFICATIONS. This Agreement may be amended or
modified only by a writing signed by the Employee and the Chairman of the Board
of the Company.

         14. GOVERNING LAW. The validity and effect of this Agreement shall be
construed under, governed by and enforced in accordance with the laws of the
State of Texas, without regard to the choice of law provisions, statutes,
regulations or principles of this or any other jurisdiction.

         15. NO CONFLICTING AGREEMENT. Employee represents and warrants that he
is not party to any agreement, contract or understanding which would prohibit
him from entering into this Agreement or performing fully his obligations
hereunder.

         16. ARBITRATION.

                  (a) Any and all disputes arising out of or in connection with
the negotiation, execution, interpretation, performance or non-performance of
this Agreement, shall be referred to and solely and finally resolved by
