Exhibit 10.51

                          EXECUTIVE SEVERANCE AGREEMENT

     This Executive Severance Agreement dated as of the 14th day of February,
1997 (the "Agreement") is made by and between VideoLan Technologies, Inc., a
Delaware corporation (the "Company"), and Steven Rothenberg (the "Executive"),
who is presently Vice President -Finance, Chief Financial Officer, and Treasurer
of the Company, in consideration of the mutual covenants herein contained and in
further consideration of services performed and to be performed by the Executive
for the Company.

                                    Recitals

     A. The Company considers the establishment and maintenance of sound and
vital management of the Company and its subsidiaries to be essential to
protecting and enhancing the best interests of the Company and its shareholders.

     B. The Company recognizes that, as is the case with many companies, the
possibility of a change of control may exist. Such possibility, and the
uncertainty and questions which it may raise among management of the Company and
its subsidiaries may result in the departure or distraction of key members of
management to the detriment of the Company's shareholders.

     C. The Company's Board of Directors has determined that appropriate steps
should be taken to encourage key members of management of the Company, such as
the Executive, to remain in the employ of the Company and perform their assigned
duties without distraction in the face of potentially disturbing circumstances
arising from the possibility of a change of control of the Company.

     NOW, THEREFORE, in consideration of the foregoing and of the covenants
herein contained, the parties hereto agree as follows:

                             Section 1 --Definitions

have reasonably known were likely to materially damage the business of the
Company and/or any Affiliate of the Company; (4) failure by the Executive to

nominated by members of the Board so approved for nomination; or (iii) the
business of the Company is being disposed of by the Company pursuant to a

greater of (A) the highest rate in effect at any time during the twelve months
immediately preceding the applicable Date of Termination, or (B) the rate in
effect immediately prior to the applicable Change in Control.

     1.4 "Contract Period" shall mean the period defined in Section 2 hereof.

reductions) does not exceed 10% of the Executive's base salary prior to such
change;

          (e) the Disability of the Executive; or

          (f) any purported termination of the Executive's employment during the

     1.8 A "Notice of Termination" shall mean a notice, from the Company or from
the Executive, which shall indicate the specific termination provision in this
Agreement relied upon and shall set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated.

                      Section 2 --Application of Agreement

extended pursuant to the following sentence (the "Coverage Period"). At midnight
on December 31, 1998, and on each annual anniversary of that time and date
thereafter, the Coverage Period shall be automatically extended for two
additional years, unless on or before such anniversary the Company notifies the
Executive in writing that it elects not to extend such period. There is one
Contract Period for each Change in Control and there may be multiple Change(s)
in Control. With respect to a termination pursuant to Section 3.2 only, the
Contract Period shall also include the period from and after a
<PAGE>

Potential Change in Control. If a Potential Change in Control occurs but a
Change in Control does not follow within one year of the Potential Change in
Control, the Contract Period shall expire on the one year anniversary of the
Potential Change in Control.

                             Section 3 --Termination

     3.1 Procedure for Termination. Any termination by the Company or by the

Executive, pursuant to this Agreement, shall be communicated by Notice of
Termination to the other parties hereto. The Executive shall not be deemed to
have been terminated for Cause unless and until there shall have been delivered
to the Executive a copy of a resolution duly adopted by the affirmative vote of
not less than a majority of the entire membership of the Board of Directors of
the Company (the "Company Board") at a meeting of the Company Board called and
held for that purpose (after reasonable notice to the Executive and an
opportunity for the Executive, together with his counsel, to be heard before the
Company Board), finding that in the good faith opinion of the Company Board, the
Executive was guilty of conduct set forth in Section 1.1 and specifying the
particulars thereof in detail.

     3.2 Termination By the Company. Upon a termination of the Executive's
employment for Cause before or during the Contract Period, the Executive shall
have no right to receive any compensation or benefits hereunder. Upon a
termination of the Executive's employment without Cause during the Contract
Period, the Executive shall be entitled to receive the benefits provided in
Section 3.4 hereof. This Agreement shall not apply to, and the Executive shall
have no right to receive any compensation or benefits hereunder in connection
with any termination of the Executive's employment by the Company other than
during a Contract Period, and Executive shall remain an "at will" employee until
a Contract Period begins, except as may be otherwise provided by a written
employment contract between the Executive and the Company.

     3.3 Termination By Executive. During the Contract Period, the Executive
shall be entitled to terminate his employment with the Company and, if such
termination is for Good Reason, to receive the benefits provided in Section 3.4
hereof. The Executive shall give the Company Notice of Termination of his
employment pursuant to this Section 3.3, and termination of the Executive's
employment shall be effective five business days after the Executive gives
notice thereof to the Company. This Agreement shall not apply to, and the
Executive shall have no right to receive any compensation or benefits hereunder
in connection with, any termination of the Executive's employment by the
Executive other than during a Contract Period, and shall not apply to
termination of the Executive's employment on account of the Executive's death,
whether or not during the Contract Period.

     3.4 Compensation Upon Termination or During Disability. If during a
Contract Period the Executive's employment shall be terminated by the Company
other than pursuant to death or for Cause, or if the Executive shall terminate
his employment for Good Reason, then the Company shall pay, or the Company shall
cause the Company to pay, to the Executive as severance 
<PAGE>

compensation in a lump sum (discounted to present value using the prime rate of
interest as published in the Wall Street Journal) on the fifth day following the
Date of Termination:

          (a) the unpaid balance of the Executive's full base salary through the
          Date of Termination at the rate in effect at the time Notice of
          Termination is given; and

          (b) an amount equal the Executive's Compensation if paid for 24 months
          following the Date of Termination, plus an additional 20% of his

          Compensation for lost bonus potential (or the maximum bonus he could
          have received for the year of termination under any written bonus plan
          of the Company in effect at the Date of Termination, if greater).

     In addition to the severance benefits set forth in (a) and (b) of this
Section 3.4, the Company shall, or the Company shall cause the Company to:

          (c) pay all legal fees and expenses incurred by the Executive
          resulting from termination (including all such fees and expenses, if
          any, incurred in contesting any such termination or in seeking to
          obtain or enforce any right or benefit provided by this Agreement, if
          the Executive is successful in that enforcement);

          (d) maintain in full force and effect, for the continued benefit of
          the Executive for the shorter of two years after the Date of
          Termination, or (2) until the Executive's death (provided that
          benefits payable to his beneficiaries shall not terminate upon his
          death), or (3) with respect to any particular plan, the date he is
          afforded a comparable benefit at a comparable cost to the Executive by
          a subsequent employer, all employee pension and welfare benefit plans
          (as defined in Section 3(1) and 3(2) of the Employer Retirement Income
          Security Act of 1974, as amended) in which Executive was entitled to
          participate immediately prior to the Change of Control (unless plans
          generally available to employees of the Company have been modified
          since the Change in Control, in which case the plans to be continued
          shall be those in effect at the Date of Termination, at the level most
          comparable to that available to the Executive at the Change in
          Control). In the event that the Executive's participation in any plan
          of the Company is prohibited, the Company shall arrange to provide the
          Executive with benefits substantially similar to those which the
          Executive is entitled to receive under plan, for such period. At the
          end of the period of coverage, the Executive shall have the option to
          have assigned to him at no cost and with no apportionment of prepaid
          premiums, any assignable insurance policy owned by the Company
          relating specifically to the Executive; and
<PAGE>

          (e) cause all stock options and stock appreciation rights and/or the
          rights held by the Executive with respect to stock in the Company
          immediately prior to the termination, if not otherwise presently
          exercisable, to become presently exercisable.

     3.5 Disability. If during the Contract Period, the Executive's employment
shall be terminated, either by the Company or by the Executive, due to the
Executive's Disability, the Company shall pay the Executive as severance
compensation the same benefits as set forth in Section 3.4(a)-(e).

     3.6 No Mitigation. The Executive shall not be required to mitigate the
amount of any payment provided for in this Section 3 by seeking other employment
or otherwise, nor shall the amount of any payment provided for in this Section 3
be reduced by any compensation earned by the Executive as the result of
employment by another employer after the Date of Termination, or otherwise.

                            Section 4 --Miscellaneous


     4.1 Successors Shall Assume. The Company will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business and/or assets of the Company or the
Company, by agreement in form and substance satisfactory to the Executive,
expressly to assume and agree to perform this Agreement in the same manner and
to the same extent that the Company or the Company would be required to perform
it if no such succession had taken place. Failure of the Company to obtain such
agreement prior to the effectiveness of any such succession shall be a breach of
this Agreement and shall entitled the Executive to compensation from the Company
in the same amount and on the same terms as the Executive would be entitled
hereunder if the Executive terminated the Executive's employment for Good
Reason, except that for purposes of implementing the foregoing, the date on
which any such succession becomes effective shall be deemed the Date of
Termination. As used in this Agreement, "Company" shall mean the Company as
defined in the preamble hereto and any successor to its business and/or assets
as aforesaid or which otherwise becomes bound by all the terms and provisions of
this Agreement by operation of law.

     4.2 Binding Effect. This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive should die while any amounts would still be payable to the Executive
hereunder if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the Executive's devisee, legatee, or other designee or, if there be
no such designee, to the Executive's estate.
<PAGE>

     4.3 Reduction of Amounts Payable. In no event shall any amount payable
under any provision of this Agreement equal or exceed an amount which would
cause the Company to forfeit, pursuant to Section 280G(a) of the Internal
Revenue Code of 1986, as amended, its deduction for any or all such amounts
payable. Pursuant to this Section 4.3, the Company's Board of Directors (or a
Committee of the Board to which compensation matters are delegated) has the
power to reduce severance benefits payable under this Agreement, if such
benefits alone or in conjunction with termination benefits provided under any
other Company plan or program, would cause the Company to forfeit otherwise
deductible payments; provided, however that no benefits payable under this
Agreement shall be reduced pursuant to this Section 4.3 to less than $1.00 below
the amount of benefits which the Company can properly deduct under Section
280G(a) of the Internal Revenue Code of 1986, as amended, and that the
Committee; and further provided that the Executive shall choose which of the
payments and benefits to retain if some payments and benefits will not be paid
hereunder.

     4.4 Notice. Any notice or request required or permitted to be given under
this Agreement shall be in writing and shall be deemed sufficiently given for
all purposes if mailed by certified mail, postage prepaid and return receipt
requested, addressed to the intended recipient at

          (a) the addresses set forth below:

<PAGE>

not be affected by any circumstances, including, without limitation, any
set-off, counterclaim, recoupment, defense or other right which the Company may
have against him or anyone else, except with respect to tax withholding required
pursuant to Section 4.11. All amounts payable by the Company hereunder shall be
paid without notice or demand. Except as expressly provided herein, the Company
waives all rights which it may now have or may hereafter have conferred upon it,
by statute or otherwise, to amend, terminate, cancel or rescind this Agreement
in whole or in part. Each and every payment made hereunder by the Company shall
be final and the Company shall not seek to recover all or any part of such
payment from the Executive or from whomsoever may be entitled thereto, for any
reason whatsoever.

     4.6 Modifications and Waivers. No provisions of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing and signed by the Executive and such officer as may be
specifically designated by the Board of Directors of the Company. No waiver by
either party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed by
such other party shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or any prior or subsequent time.

     4.7 Entire Agreement. In the event that Executive is entitled to receive
any payment under ss.3.4 of this Agreement, Executive shall not be entitled to
receive any payments pursuant to the Employment Agreement between the Executive
and the Company dated September 6, 1995 that relate to compensation payable upon
or after termination of employment. No agreements or representations, oral or
otherwise, express or implied, with respect to the subject matter hereof have
been made by either party which are not set forth expressly in this Agreement.

     4.8 Governing Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the Commonwealth

of Kentucky.

     4.9 Validity. The invalidity or unenforceability of any provisions of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

     4.10 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

     4.11 Payroll and Withholding Taxes. The Company may withhold from any
amounts payable to the Executive hereunder all federal, state, city or other
taxes that the Company may reasonably determine are required to be withheld
pursuant to any applicable law or regulation.

day and year first above written.
