                              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

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.

         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.

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

hereunder.

with the arbitration.
