Exhibit 4.1

                                DESTRON/IDI, INC.

                                STOCK OPTION PLAN

I.      Purpose

     The Destron/IDI, Inc. Stock Option Plan (the "Plan") provides for the grant
of Stock Options to Employees of Destron/ IDI, Inc. (the "Company"), and such of
its  subsidiaries  (as defined in Section 424(f) of the Internal Revenue Code of
1986,  as amended  (the  "Code")) as the Board of  Directors of the Company (the
"Board") shall from time to time designate  ("Participating  Subsidiaries"),  in
order to advance the interests of the Company and its Participating Subsidiaries
through the motivation, attraction and retention of their respective Employees.

II.     Incentive Stock Options and Non-Incentive Stock Options

     The Stock Options granted under the Plan may be either:

          (a)  Incentive  Stock  Options  ("ISOs")  which  are  intended  to  be
     "Incentive  Stock  Options"  as that term is defined in Section  422 of the
     Code; or

          (b)  Nonstatutory  Stock  Options  ("NSOs")  which are  intended to be
     options that do not qualify as "Incentive  Stock Options" under Section 422
     of the Code.

All Stock Options shall be ISOs unless the Option Agreement  clearly  designates
the Stock Options granted  thereunder,  or a specified portion thereof, as NSOs.
Subject to the other  provisions of the Plan, a Participant may receive ISOs and
NSOs at the same time, provided that the ISOs and NSOs are clearly designated as
such.

     Except as otherwise  expressly  provided herein,  all of the provisions and
requirements of the Plan relating to Stock Options shall apply to ISOs and NSOs.

III.    Administration

     3.1  Committee. With respect to grants of Stock Options to Employees  other
than officers and directors of the Company,  the Plan shall be administered by a
committee  ("Committee")  composed  of at  least  two  members  of the  Board of

                                       1
<PAGE>

Directors.  With respect to grants of Stock  Options to officers and  directors,
the Plan shall be administered by the Board of Directors,  if each director is a
Disinterested  Person,  or by a committee of two or more directors,  all of whom
are  Disinterested  Persons.  Such  committee may be the Committee if all of the
members thereof are Disinterested  Persons,  or a special committee appointed by
the Board of  Directors  composed  of at least two  Disinterested  Persons.  The
Committee  or the  Board,  as the case may be,  shall  have  full  authority  to
administer the Plan, including authority to interpret and construe any provision
of the Plan and any Stock Option granted thereunder, and to adopt such rules and
regulations  for  administering  the Plan as it may deem  necessary  in order to
comply with the  requirements  of the Code, in order that Stock Options that are
intended to be ISOs will be  classified  as incentive  stock  options  under the
Code,  or in order to conform to any  regulation  or to any change in any law or
regulation  applicable  thereto.  The Committee or the Board may delegate any of
its  responsibilities  under the Plan,  other than its  responsibility  to grant
Stock  Options or to interpret  and construe the Plan. If the Board of Directors
is composed  entirely  of  Disinterested  Persons,  the Board of  Directors  may
reserve to itself any of the  authority  granted to the  Committee  as set forth
herein,   and  it  may  perform  and   discharge   all  of  the   functions  and
responsibilities of the Committee at any time that a duly constituted  Committee
is not appointed  and serving.  All  references  in the Plan to the  "Committee"
shall be  deemed  to  refer to the  Board of  Directors  whenever  the  Board is
discharging the powers and responsibilities of the Committee, and to any special
committee appointed by the Board to administer particular aspects of the Plan.

     3.2  Actions of Committee.  All actions taken and all  interpretations  and
determinations made by the Committee in good faith (including  determinations of
Fair Market Value) shall be final and binding upon all Participants, the Company
and all other interested persons. No member of the Committee shall be personally
liable for any action,  determination or interpretation  made in good faith with
respect to the Plan,  and all  members of the  Committee  shall,  in addition to
their rights as directors, be fully protected by the Company with respect to any
such action, determination or interpretation.

IV.     Definitions

     4.1  "Stock  Option." A Stock Option is the right granted under the Plan to
an  Employee  to  purchase,  at such time or times  and at such  price or prices
("Option  Price") as are  determined by the  Committee,  the number of shares of
Common Stock determined by the Committee.

     4.2  "Common Stock." A share of Common Stock means a  share  of  authorized
but unissued or reacquired Common Stock (no par value) of the Company.

     4.3  "Fair Market  Value." If the Common Stock is not traded  publicly, the
Fair Market Value of a share of Common Stock on any date shall be determined, in
good  faith,  by the  Committee  after such  consultation  with  outside  legal,
accounting  and other  experts  as the  Committee  may deem  advisable,  and the
Committee  shall  maintain a written  record of its method of  determining  such

                                       2
<PAGE>

value. If the Common Stock is traded publicly,  the Fair Market Value of a share
of Common Stock on any date shall be the average of the  representative  closing
bid and asked  prices,  as  quoted by the  National  Association  of  Securities
Dealers through NASDAQ (its automated system for reporting quotas), for the date
in  question  or, if the Common  Stock is listed on the NASDAQ  National  Market
System or is listed on a national stock exchange,  the officially quoted closing
price on NASDAQ or such exchange as the case may be, on the date in question.

     4.4  "Employee."  An  Employee  is  an  employee  of  the  Company  or  any
Participating Subsidiary.

     4.5  "Participant."  A Participant is an Employee to whom a Stock Option is
granted.

     4.6  "Disinterested  Person." A  Disinterested  Person is a director of the
Company  who,  during  the  shorter  of (a) the one year  prior to service as an
administrator  of the  Plan,  or (b) the  period  between  the date on which the
Company's  Common Stock is registered  pursuant to Section 12 of the  Securities
Exchange Act of 1934, as amended, (the "1934 Act") and the director's service as
an administrator of the Plan, has not been granted or awarded equity  securities
pursuant to the Plan or any other plan of the  Company or any of its  affiliates
except  as may be  permitted  by Rule  16b-3(c)(2)  under  the  1934  Act or any
successor to such rule.

V.       Eligibility and Participation

     Grants of Stock  Options  may be made to  Employees  of the  Company or any
Participating  Subsidiary,  including  directors  of the  Company  who are  also
Employees,  but directors who are not Employees shall not be eligible to receive
Stock Options under the Plan.  The Committee  shall from time to time  determine
the Employees to whom Stock  Options  shall be granted,  the number of shares of
Common Stock  subject to each Stock Option to be granted to each such  Employee,
the Option  Price of such Stock  Options  and the terms and  provisions  of such
Stock Options, all as provided in the Plan. The Option Price of any ISO shall be
not less than the Fair  Market  Value of a share of Common  Stock on the date on
which the Stock  Option is granted,  but the Option  Price of an NSO may be less
than the Fair Market  Value on the date the NSO is granted if the  Committee  so
determines.  If an ISO is granted to an Employee who then owns stock  possessing
more than 10% of the total combined  voting power of all classes of stock of the
Company or any parent or subsidiary corporation of the Company, the Option Price
of such ISO shall be at least 110% of the Fair Market  value of the Common Stock
subject  to the ISO at the time such ISO is  granted,  and such ISO shall not be
exercisable after five years after the date on which it was granted.  Each Stock
Option shall be evidenced by a written agreement ("Option Agreement") containing
such  terms and  provisions  as the  Committee  may  determine,  subject  to the
provisions of the Plan.

                                       3

VI.     Shares of Common Stock Subject to the Plan

     6.1  Maximum Number. The maximum aggregate number of shares of Common Stock
that may be made  subject to Stock  Options  shall be 1,300,000  authorized  but
unissued shares.  The aggregate Fair Market Value (determined as of the time the
ISO is granted) of the Common  Stock as to which all ISOs granted to an Employee
may first  become  exercisable  in a  particular  calendar  year may not  exceed
$100,000.  If any  shares of  Common  Stock  subject  to Stock  Options  are not
purchased or otherwise  paid for before such Stock Options  expire,  such shares
may again be made subject to Stock Options.

     6.2  Capital  Changes.  In the event any  changes are made to the shares of
Common  Stock  (whether  by reason  of  merger,  consolidation,  reorganization,
recapitalization,  stock  dividend in excess of ten percent  (10%) at any single
time,  stock  split,  combination  of  shares,  exchange  of  shares,  change in
corporate structure or otherwise), appropriate adjustments shall be made in: (i)
the number of shares of Common Stock  theretofore made subject to Stock Options,
and in the  purchase  price of said  shares;  and (ii) the  aggregate  number of
shares  which may be made  subject  to Stock  Options.  If any of the  foregoing
adjustments   shall  result  in  a  fractional  share,  the  fraction  shall  be
disregarded,  and the Company shall have no obligation to make any cash or other
payment with respect to such a fractional share.

VII.    Exercise of Stock Options

     7.1  Time of  Exercise. Subject to the  provisions  of the Plan,  including
without  limitation  Section  7.5,  the  Committee,  in  its  discretion,  shall
determine  the time when a Stock Option,  or a portion of a Stock Option,  shall
become  exercisable,  and the time when a Stock Option,  or a portion of a Stock
Option,  shall  expire.  Such  time or times  shall be set  forth in the  Option
Agreement  evidencing such Stock Option.  An ISO shall expire, to the extent not
exercised,  no later  than  the  tenth  anniversary  of the date on which it was
granted, and an NSO shall expire, to the extent not exercised, no later than ten
years after the date on which it was granted.  The Committee may  accelerate the
vesting  of any  Participant's  Stock  Option  by giving  written  notice to the
Participant.  Upon receipt of such notice, the Participant and the Company shall
amend the Option Agreement to reflect the new vesting schedule. The acceleration
of the exercise period of a Stock Option shall not affect the expiration date of
that Stock Option.

     7.2  Exchange of Outstanding  Stock. The Committee, in its sole discretion,
may permit a  Participant  to  surrender  to the Company  shares of Common Stock
previously  acquired by the Participant as part or full payment for the exercise
of a Stock Option.  Such surrendered shares shall be valued at their Fair Market
Value on the date of exercise.

     7.3  Use of Promissory Note; Exercise Loans. The Committee may, in its sole
discretion,  impose terms and conditions,  including  conditions relating to the
manner and timing of payments,  on the exercise of Stock Options. Such terms and
conditions  may include,  but are not limited to,  permitting a  Participant  to
deliver to the Company his  promissory  note as full or partial  payment for the
exercise of a Stock Option;  provided that,  with respect to any promissory note
given as payment or partial  payment for the  exercise  of an ISO,  all terms of
such note shall be  determined  at the time a Stock  Option is  granted  and set
forth in the  Option  Agreement.  The  Committee,  in its sole  discretion,  may
authorize  the Company to make a loan to a Participant  in  connection  with the
exercise of Stock Options, or authorize the Company to arrange or guaranty loans
to a Participant by a third party.

                                       4
<PAGE>

     7.4  Stock Restriction  Agreement. The Committee may provide that shares of
Common Stock  issuable upon the exercise of a Stock Option shall,  under certain
conditions,  be subject to restrictions whereby the Company has a right of first
refusal with respect to such shares or a right or obligation  to repurchase  all
or a portion of such shares, which restrictions may survive a Participant's term
of employment  with the Company.  The  acceleration  of time or times at which a
Stock Option  becomes  exercisable  may be  conditioned  upon the  Participant's
agreement to such restrictions.

     7.5  Termination  of  Employment   Before  Exercise.   If  a  Participant's
employment  with the Company or a Participating  Subsidiary  shall terminate for
any reason other than the Participant's  disability,  any Stock Option then held
by the Participant,  tc the extent then exercisable  under the applicable Option
Agreement(s),  shall remain  exercisable after the termination of his employment
for a period of three months (but, in the case of an ISO, in no event beyond ten
years from the date of grant of the ISO).  If the  Participant's  employment  is
terminated  because the  Participant  is disabled  within the meaning of Section
22(e)(3)  of the Code,  any Stock  Option then held by the  Participant,  to the
extent then exercisable under the applicable Option  Agreement(s),  shall remain
exercisable  after  the  termination  of his  employment  for a period of twelve
months  (but,  in the case of an ISO, in no event beyond ten years from the date
of grant of the ISO). If the Stock Option is not exercised during the applicable
period,  it shall be deemed to have been  forfeited  and of no further  force or
effect.

     7.6  Disposition  of Forfeited  Stock  Options.  Any shares of Common Stock
subject to Stock  Options  forfeited by a  Participant  shall not  thereafter be
eligible  for  purchase  by the  Participant  but may be made  subject  to Stock
Options granted to other Participants.

VIII.   No Contract of Employment

     Nothing  in this  Plan  shall  confer  upon the  Participant  the  right to
continue in the employ of the  Company,  or any  Participating  Subsidiary,  nor
shall  it  interfere  in any way  with the  right  of the  Company,  or any such
Participating  Subsidiary,  to  discharge  the  Participant  at any time for any
reason  whatsoever,  with or without  cause.  Nothing in this Article VIII shall
affect any rights or  obligations  of the Company or any  Participant  under any
written contract of employment.

                                       5

IX.      No Rights as a Stockholder

     A Participant  shall have no rights as a stockholder  with respect,  to any
shares of Common Stock subject to a Stock Option.  Except as provided in Section
6.2, no adjustment  shall be made in the number of shares of Common Stock issued
to a Participant,  or in any other rights of the Participant  upon exercise of a
Stock Option by reason of any dividend,  distribution  or other right granted to
stockholders  for which the record  date is prior to the date of exercise of the
Participant's Stock Option.

X.       Assignability

     No Stock  Option  right  granted  under  this  Plan,  nor any other  rights
acquired by a Participant  under this Plan,  shall be assignable or transferable
by a Participant, other than by will or the laws of descent and distribution or,
in the case of an NSO,  pursuant  to a  qualified  domestic  relations  order as
defined by the Code, Title I of the Employee  Retirement Income Security Act, or
the rules thereunder. Notwithstanding the preceding sentence, the Committee may,
in its  sole  discretion,  permit  the  assignment  or  transfer  of an NSO by a
Participant  other than an officer or director,  and the  exercise  thereof by a
person  other  than  such  Participant,  on such  terms  and  conditions  as the
Committee  in its  sole  discretion  may  determine.  Any  such  terms  shall be
determined at the time the NSO is granted,  and shall be set forth in the Option
Agreement.  In the event of his death,  the Stock Option may be exercised by the
Personal   Representative  of  the  Participant's  estate  or,  if  no  Personal
Representative  has been  appointed,  by the successor or successors in interest
determined under the Participant's  will or under the applicable laws of descent
and distribution.

XI.      Merger or Liquidation of the Company

     If the Company or its  stockholders  enter into an  agreement to dispose of
all, or  substantially  all, of the assets or  outstanding  capital stock of the
Company  by means of a sale or  liquidation,  or a merger or  reorganization  in
which  the  Company  is  not  the  surviving  corporation,   all  Stock  Options
outstanding  under the Plan as of the day before the  consummation of such sale,
liquidation,  merger or reorganization,  to the extent not exercised,  shall for
all  purposes  under this Plan become  exercisable  in full as of such date even
though the dates of  exercise  established  pursuant to Section 7.1 have not yet
occurred,  unless the Board shall have prescribed  other terms and conditions to
the exercise of the Stock Options, or otherwise modified the Stock Options.

XII.    Amendment

     The Board may from time to time alter,  amend,  suspend or discontinue  the
Plan, including,  where applicable,  any modifications or amendments as it shall
deem advisable in order that ISOs will be classified as incentive  stock options
under the Code, or in order to conform to any regulation or to any change in any
law or regulation  applicable thereto;  provided,  however,  that no such action

                                       6
<PAGE>

shall adversely  affect the rights and obligations with respect to Stock Options
at any time outstanding under the Plan; and provided further that no such action
shall, without the approval of the stockholders of the Company, (i) increase the
maximum  number  of shares of Common  Stock  that may be made  subject  to Stock
Options (unless  necessary to effect the  adjustments  required by Section 6.2),
(ii) materially  increase the benefits accruing to Participants  under the Plan,
or (iii) materially  modify the requirements as to eligibility for participation
in the Plan.

XIII.   Registration of Optioned Shares

     The Stock  Options  shall not be  exercisable  unless the  purchase of such
optioned shares is pursuant to an applicable  effective  registration  statement
under the Securities Act of 1933, as amended (the "1933 Act"), or unless, in the
opinion of counsel to the Company, the proposed purchase of such optioned shares
would be exempt from the registration  requirements of the 1933 Act and from the
registration or qualification requirements of applicable state securities laws.

XIV.    Withholding Taxes

     The Company or Participating  Subsidiary may take such steps as it may deem
necessary or appropriate  for the  withholding of any taxes which the Company or
the  Participating  Subsidiary  is  required  by any  law or  regulation  or any
governmental authority, whether federal, state or local, domestic or foreign, to
withhold in connection with any Stock Option including,  but not limited to, the
withholding of all or any portion of any payment or the  withholding of issuance
of shares of Common  Stock to be issued upon the  exercise  of any Stock  Option
until the Participant reimburses the Company or Participating Subsidiary for the
amount the Company or  Participating  Subsidiary  is  required to withhold  with
respect to such taxes,  or cancelling any portion of such payment or issuance in
an amount  sufficient  to  reimburse  itself for the amount it is required to so
withhold.

XV.     Brokerage Arrangements

     The Committee,  in its discretion,  may enter into arrangements with one or
more  banks,   brokers  or  other  financial   institutions  to  facilitate  the
disposition of shares acquired upon exercise of Stock Options including, without
limitation,  arrangements  for the simultaneous  exercise of Stock Options,  and
sale of the shares acquired upon such exercise.

                                       7
<PAGE>

XVI.    Nonexclusivity of the Plan

     Neither  the  adoption of the Plan by the Board nor the  submission  of the
Plan to  stockholders of the Company for approval shall be construed as creating
any  limitations  on the power or  authority of the Board to adopt such other or
additional  incentive or other  compensation  arrangements of whatever nature as
the Board may deem necessary or desirable or preclude or limit the  continuation
of any other plan,  practice or arrangement  for the payment of  compensation or
fringe benefits to employees  generally,  or to any class or group of employees,
which the Company or any  Participating  Subsidiary  now has  lawfully  put into
effect,  including,  without limitation,  any retirement,  pension,  savings and
stock purchase  plan,  insurance,  death and  disability  benefits and executive
short-term incentive plans.

XVII.   Effective Date

     This Plan was adopted by the Board of Directors and became effective on May
21, 1992 and [was approved by the Company's  stockholders  on July 31, 1992.] No
Stock Options shall be granted  subsequent to ten years after the effective date
of the  Plan.  Stock  Options  outstanding  subsequent  to ten  years  after the
effective  date of the Plan shall  continue to be governed by the  provisions of
the Plan.

I.       Purpose

     The Destron/IDI,  Inc.  Consultants Stock Option Plan (the "Plan") provides
for the  grant of  Stock  Options  to  Consultants  of  Destron/IDI,  Inc.  (the
"Company"),  and  such of its  subsidiaries  as the  Board of  Directors  of the
Company  (the  "Board")  shall  from  time  to  time  designate  ("Participating
Subsidiaries"),  in order to advance the  interests  of the Company  through the
motivation, attraction and retention of their respective Consultants.

II.      Non-Incentive Stock Options

     The Stock  Options  granted  under  the Plan  shall be  nonstatutory  stock
options  ("NSOs")  which are  intended  to be  options  that do not  qualify  as
"incentive  stock  options"  under  Section 422 of the Internal  Revenue Code of
1986, as amended (the "Code").

III.     Administration

     3.1  Committee.  With  respect  to  grants  of Stock Options to Consultants
other than officers and directors of the Company, the Plan shall be administered
by a  committee  ("Committee")  composed of at least two members of the Board of
Directors.  With respect to grants of Stock  Options to officers and  directors,
the Plan shall be administered by the Board of Directors,  if each director is a
Disinterested  Person,  or by a committee of two or more directors,  all of whom
are  Disinterested  Persons.  Such  committee may be the Committee if all of the
members thereof are Disinterested  Persons,  or a special committee appointed by
the Board of  Directors  composed  of at least two  Disinterested  Persons.  The
Committee  or the  Board,  as the case may be,  shall  have  full  authority  to
administer the Plan, including authority to interpret and construe any provision
of the Plan and any Stock Option granted thereunder, and to adopt such rules and
regulations  for  administering  the Plan as it may deem  necessary  in order to
comply  with  the  requirements  of the  Code,  or in order  to  conform  to any
regulation or to any change in any law or  regulation  applicable  thereto.  The
Committee or the Board may delegate any of its responsibilities  under the Plan,
other  than its  responsibility  to grant  Stock  Options  or to  interpret  and
construe  the  Plan.  If  the  Board  of  Directors  is  composed   entirely  of
Disinterested  Persons,  the Board of Directors may reserve to itself any of the
authority  granted to the Committee as set forth herein,  and it may perform and
discharge all of the functions and responsibilities of the Committee at any time
that a duly constituted  Committee is not appointed and serving.  All references
in the  Plan to the  "Committee"  shall  be  deemed  to  refer  to the  Board of
Directors whenever the Board is discharging the powers and  responsibilities  of
the Committee, and to any special committee appointed by the Board to administer
particular aspects of the Plan.

     3.2  Actions of  Committee. All actions taken and all  interpretations  and

and all other interested persons. No member of the Committee shall be personally
liable for any action,  determination or interpretation  made in good faith with
respect to the Plan,  and all  members of the  Committee  shall,  in addition to
their rights as directors, be fully protected by the Company with respect to any
such action determination or interpretation.

V.      Eligibility and Participation

     Grants of Stock  Options may be made to  Consultants  of the Company or any
Participating  Subsidiary,  including  directors  of the  Company  who  are  not
employees.  The Committee  shall from time to time determine the  Consultants to
whom  Stock  Options  shall be  granted,  the  number of shares of Common  Stock
subject to each Stock Option to be granted to each such  Consultant,  the Option
Price of such Stock Options and the terms and  provisions of such Stock Options,
all as  provided  in the Plan.  The Option  Price of an NSO may be less than the
Fair Market Value on the date the NSO is granted if the Committee so determines.
Each Stock Option shall be evidenced by a written agreement ("Option Agreement")
containing such terms and provisions as the Committee may determine,  subject to
the provisions of the Plan.

VI.     Shares of Common Stock Subject to the Plan

     6.1  Maximum Number. The maximum aggregate number of shares of Common Stock
that may be made  subject  to Stock  Options  shall be  500,000  authorized  but
unissued shares.  If any shares of Common Stock subject to Stock Options are not
purchased or otherwise  paid for before such Stock Options  expire,  such shares
may again be made subject to Stock Options.

     6.2  Capital  Changes.  In the event any  changes are made to the shares of
Common  Stock  (whether  by reason  of  merger,  consolidation,  reorganization,
recapitalization,  stock  dividend in excess of ten percent  (10%) at any single
time,  stock  split,  combination  of  shares,  exchange  of  shares,  change in
corporate structure or otherwise), appropriate adjustments shall be made in: (i)
the number of shares of Common Stock  theretofore made subject to Stock Options,
and in the  purchase  price of said  shares;  and (ii) the  aggregate  number of
shares  which may be made  subject  to Stock  Options.  If any of the  foregoing
adjustments   shall  result  in  a  fractional  share,  the  fraction  shall  be
disregarded,  and the Company shall have no obligation to make any cash or other
payment with respect to such a fractional share.

VII. Exercise of Stock Options

     7.1  Time of Exercise. Subject to the provisions of the Plan the Committee,
in its discretion, shall determine the time when a Stock Option, or a portion of
a Stock Option, shall become exercisable, and the time when a Stock Option, or a
portion of a Stock Option,  shall expire.  Such time or times shall be not forth
in the Option Agreement  evidencing such Stock Option.  An NSO shall expire,  to
the extent not  exercised,  no later than five years  after the date on which it
was granted. The Committee may accelerate the vesting of any Participant's Stock
Option by giving written notice to the Participant. Upon receipt of such notice,
the Participant and the Company shall amend the Option  Agreement to reflect the
new vesting schedule.  The acceleration of the exercise period of a Stock Option
shall not affect the expiration date of that Stock Option.

     7.2  Exchange of Outstanding Stock. The Committee,  in its sole discretion,
may permit a  Participant  to  surrender  to the Company  shares of Common Stock
previously  acquired by the Participant as part or full payment for the exercise
of a Stock Option.  Such surrendered shares shall be valued at their Fair Market
Value on the date of exercise.

     7.3  Use of Promissory Note; Exercise Loans. The Committee may, in its sole
discretion,  impose terms and conditions,  including  conditions relating to the
manner and timing of payments,  on the exercise of Stock Options. Such terms and
conditions  may include,  but are not limited to,  permitting a  Participant  to
deliver to the Company his  promissory  note as full or partial  payment for the
exercise of a Stock Option.

     7.4  Stock Restriction Agreement.  The Committee may provide that shares of
Common Stock  issuable upon the exercise of a Stock Option shall,  under certain
conditions,  be subject to restrictions whereby the Company has a right of first
refusal with respect to such shares or a right or obligation  to repurchase  all
or a portion of such shares.  The acceleration of time or times at which a Stock
Option becomes  exercisable may be conditioned upon the Participant's  agreement
to such restrictions.

     7.5  Disposition  of Forfeited  Stock  Options.  Any shares of Common Stock
subject to Stock  Options  forfeited by a  Participant  shall not  thereafter be
eligible  for  purchase  by the  Participant  but may be made  subject  to Stock
Options granted to other Participants.

VIII.   No Contract

     Nothing  in this  Plan  shall  confer  upon the  Participant  the  right to
continue as a Consultant of the Company,  or any Participating  Subsidiary,  nor
shall  it  interfere  in any way  with the  right  of the  Company,  or any such
Participating  Subsidiary,  to  terminate  the  Participant  at any time for any
reason  whatsoever,  with or without  cause.  Nothing in this Article VIII shall
affect any rights or  obligations  of the Company or any  Participant  under any
written contract.

IX.     No Rights as a Stockholder

     A  Participant  shall have no rights as a  stockholder  with respect to any
shares of Common Stock subject to a Stock Option.  Except as provided in Section
6.2, no adjustment  shall be made in the number of shares of Common Stock issued
to a Participant,  or in any other rights of the Participant  upon exercise of a
Stock Option by reason of any dividend,  distribution  or other right granted to
stockholders  for which the record  date is prior to the date of exercise of the
Participant's Stock Options.

X.      Assignability

     The  Committee  may,  in its sole  discretion,  permit  the  assignment  or
transfer of a stock option by a  Participant  other than an officer or director,
and the exercise thereof by a person other than such Participant,  on such terms
and conditions as the Committee in its sole  discretion may determine.  Any such
terms shall be determined at the time the stock option is granted,  and shall be
set forth in the Option  Agreement.  In the event of his death, the Stock Option
may be exercised by the Personal  Representative of the Participant's estate or,
if no Personal Representative has been appointed, by the successor or successors
in interest determined under the Participant's will or under the applicable laws
of descent and distribution.

XI.     Merger or Liquidation of the Company

     If the Company or its  stockholders  enter into an  agreement to dispose of
all, or  substantially  all, of the assets or  outstanding  capital stock of the
Company by means of a sale or liquidation or a merger or reorganization in which
the Company is not the  surviving  corporation,  all Stock  Options  outstanding
under the Plan as of the day before the consummation of such sale,  liquidation,
merger or  reorganization,  to the extent not exercised,  shall for all purposes
under this Plan become exercisable in full as of such date even though the dates
of exercise  established  pursuant to Section 7.1 have not yet occurred,  unless
the Board shall have  prescribed  other terms and  conditions to the exercise of
the Stock Options, or otherwise modified the Stock Options.

XII.    Amendment

     The Board may from time to time alter,  amend,  suspend or discontinue  the
Plan, including,  where applicable,  any modifications or amendments as it shall
deem advisable in order to conform to any regulation or to any change in any law
or regulation applicable thereto;  provided,  however, that no such action shall
adversely affect the rights and obligations with respect to Stock Options at any
time outstanding under the Plan; and provided further that no such action shall,
without the  approval of the  stockholders  of the  Company,  (i)  increase  the
maximum  number  of shares of Common  Stock  that may be made  subject  to Stock
Options (unless  necessary to effect the  adjustments  required by Section 6.2),
(ii) materially  increase the benefits accruing to Participants  under the Plan,
or (iii) materially  modify the requirements as to eligibility for participation
in the Plan.

XIII.   Registration of Optioned Shares

     The Stock  Options  shall not be  exercisable  unless the  purchase of such
optioned shares is pursuant to an applicable  effective  registration  statement
under the Securities Act of 1933, as amended (the "1933 Act"), or unless, in the
opinion of counsel to the Company, the proposed purchase of such optioned shares
would be exempt from the registration  requirements of the 1933 Act and from the
registration or qualification requirements of applicable state securities laws.

XIV.    Withholding Taxes

     The Company or Participating  Subsidiary may take such steps as it may deem
necessary or appropriate  for the  withholding of any taxes which the Company or
the  Participating  Subsidiary  is  required  by any  law or  regulation  or any
governmental authority, whether federal, state or local, domestic or foreign, to
withhold in connection with any Stock Option including,  but not limited to, the
withholding of all or any portion of any payment or the  withholding of issuance
of shares of Common  Stock to be issued upon the  exercise  of any Stock  Option
until the Participant reimburses the Company or Participating Subsidiary for the
amount the Company or  Participating  Subsidiary  is  required to withhold  with
respect to such taxes,  or canceling  any portion of such payment or issuance in
an amount  sufficient  to  reimburse  itself for the amount it is required to so
withhold.

XV.     Brokerage Arrangements

     The Committee,  in its discretion,  may enter into arrangements with one or
more  banks,   brokers  or  other  financial   institutions  to  facilitate  the
disposition of shares acquired upon exercise of Stock Options including, without
limitation,  arrangements  for the simultaneous  exercise of Stock Options,  and
sale of the shares acquired upon such exercise.

XVI.    Nonexclusivity of the Plan

     Neither  the  adoption of the Plan by the Board nor the  submission  of the
Plan to  stockholders of the Company for approval shall be construed as creating
any  limitations  on the power or  authority of the Board to adopt such other or
additional  incentive or other  compensation  arrangements of whatever nature as
the Board may deem necessary or desirable or preclude or limit the  continuation
of any other plan,  practice or arrangement  for the payment of  compensation or
fringe benefits to employees  generally,  or to any class or group of employees,
which Company or any Participating  Subsidiary now has lawfully put into effect,
including,  without  limitation,  any  retirement,  pension,  savings  and stock
purchase plan, insurance, death and disability benefits and executive short-term
incentive plans.

XVII.   Effective Date

     This Plan was adopted by the Board of  Directors  and became  effective  on
October 16, 1992.  No Stock  Options  shall be granted  subsequent  to ten years
after the effective date of the Plan.  Stock Options  outstanding  subsequent to
ten years after the effective  date of the Plan shall continue to be governed by
the provisions of the Plan.
