         SECTION 2. Administration.

         The Plan shall be administered by the Board of Directors or by a
Committee of not less than three Disinterested Persons, who shall be appointed
by the Board of Directors of the Company and who shall serve at the pleasure of
the Board.

         The Committee shall have the power and authority to grant to eligible
employees and consultants of the Company (which consultants shall serve pursuant
to a written agreement with the Company), pursuant to the terms of the Plan: (i)
Stock Options, or (ii) Restricted Stock.


                                        2
<PAGE>


         In particular, the Committee shall have the authority:

         (i)      to select the officers and other key employees of the Company
                  and its Subsidiaries and consultants to whom Stock Options
                  and/or Restricted Stock awards may from time to time be
                  granted hereunder;

         (ii)     to determine whether and to what extent Incentive Stock
                  Options, Non-Qualified Stock Options or Restricted Stock
                  awards, or a combination of the foregoing, are to be granted
                  hereunder;

         (iii)    to determine the number of shares to be covered by each such
                  award granted hereunder;

         (iv)     to determine the terms and conditions, not inconsistent with
                  the terms of the Plan, of any award granted hereunder
                  (including, but not limited to, any restriction on any Stock
                  Option or other award and/or the shares of Stock relating
                  thereto); and

         (v)      to determine whether, to what extent and under what
                  circumstances Stock and other amounts payable with respect to
                  an award under this Plan shall be deferred either
                  automatically or at the election of the participant.

         The Committee shall have the authority to adopt, alter and repeal such
administrative rules, guidelines and practices governing the Plan as it shall,
from time to time, deem advisable; to interpret the terms and provisions of the
Plan and any award issued under the Plan (and any agreements relating thereto);
and to otherwise supervise the administration of the Plan. The Committee may
delegate its authority to officers of the Company for the purpose of selecting
employees who are not officers of the Company for purposes of (i) above.

         All decisions made by the Committee pursuant to the provisions of the
Plan shall be final and binding on all persons, including the Company and Plan
participants.

         SECTION 3. Stock Subject to Plan.

         The total number of shares of Stock reserved and available for
distribution under the Plan shall be 1,770,000. Such shares may consist, in
whole or in part, of authorized and unissued shares.

         If any shares that have been optioned ceased to be subject to Options,
or if any shares subject to any Restricted Stock award granted hereunder are
forfeited or such award otherwise terminates without a payment being made to the
participant, such shares shall again be available for distribution in connection
with future awards under the Plan.


                                        3
<PAGE>


         In the event of any merger, reorganization, consolidation,
recapitalization, stock dividend, other change in corporate structure affecting
the Stock, or spin-off or other distribution of assets to shareholders, such
substitution or adjustment shall be made in the aggregate number of shares
reserved for issuance under the Plan, in the number and option price of shares
subject to outstanding options granted under the Plan, and in the number of
shares subject to Restricted Stock awards granted under the Plan as may be
determined to be appropriate by the Committee, in its sole discretion, provided
that the number of shares subject to any award shall always be a whole number.

         SECTION 4. Eligibility.

         Officers, consultants (which consultants shall serve pursuant to a
written agreement with the Company) and other key employees of the Company and
Subsidiaries who are responsible for or contribute to the management, growth
and/or profitability of the business of the Company and its Subsidiaries are
eligible to be granted Stock Options or Restricted Stock awards under the Plan.
The optionees and participants under the Plan shall be selected from time to
time by the Committee, in its sole discretion, from among those eligible, and
the Committee shall determine, in its sole discretion, the number of shares
covered by each award.

         SECTION 5. Stock Options.

         Any Stock Option granted under the Plan shall be in such form as the
Committee may from time to time approve.

         The Stock Options granted under the Plan may be of two types: (i)
Incentive Stock Options and (ii) Non-Qualified Stock Options. No Incentive Stock
Options shall be granted under the Plan more than ten years after the Plan is
adopted.

         The Committee shall have the authority to grant any optionee Incentive
Stock Options, Non-Qualified Stock Options, or both types of options. To the
extent that any option does not qualify as an Incentive Stock Option, it shall
constitute a separate Non-Qualified Stock Option.

         Anything in the Plan to the contrary notwithstanding, no term of this
Plan relating to Incentive Stock Options shall be interpreted, amended or
altered, nor shall any discretion or authority granted under the Plan be so
exercised, so as to disqualify either the Plan or any Incentive Stock Option
under Section 422A of the Code. The preceding sentence shall not preclude any
modification or amendment to an outstanding Incentive Stock Option, whether or
not such modification or amendment results in disqualification of such Option as
an Incentive Stock Option, provided the optionee consents in writing to the
modification or amendment.

         Options granted under the Plan shall be subject to the following terms
and conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the Plan, as the Committee shall deem desirable.


                                        4
<PAGE>


         (a) Option Price. The option price per share of Stock purchasable under
a Stock Option shall be determined by the Committee at the time of grant and
may, except as provided in this paragraph, be less than the Fair Market Value of
the Stock on the date of the grant of the Option. In no event shall the option
price per share of Stock purchasable under an Incentive Stock Option be less
than 100% of the Fair Market Value of the Stock on the date of the grant of the
option. If an employee owns or is deemed to own (by reason of the attribution
rules applicable under Section 425(d) of the Code) more than 10% of the combined
voting power of all classes of stock of the Company or any Parent Corporation or
Subsidiary and an Incentive Stock Option is granted to such employee, the option
price shall be no less than 110% of the Fair Market Value of the Stock on the
date the option is granted. No Non-Qualified Stock Option shall have an option
price less than 85% of the Fair Market Value of the Stock on the date of grant.

         (b) Option Term. The term of each Stock Option shall be fixed by the
Committee, but no Incentive Stock Option shall be exercisable more than ten
years after the date the option is granted. If an employee owns or is deemed to
own (by reason of the attribution rules of Section 425(d) of the Code) more than
10% of the combined voting power of all classes of stock of the Company or any
Parent Corporation or Subsidiary and an Incentive Stock Option is granted to
such employee, the term of such option shall be no more than five years from the
date of grant.

         (c) Exercisability. Stock Options shall be exercisable at such time or
times as determined by the Committee at or after grant. If the Committee
provides, in its discretion, that any option is exercisable only in
installments, the Committee may waive such installment exercise provisions at
any time.

         (d) Method of Exercise. Stock Options may be exercised in whole or in
part at any time during the option period by giving written notice of exercise
to the Company specifying the number of shares to be purchased. Such notice
shall be accompanied by payment in full of the purchase price, either by
certified or bank check, or by any other form of legal consideration deemed
sufficient by the Committee and consistent with the Plan's purpose and
applicable law, including promissory notes or a properly executed exercise
notice together with irrevocable instructions to a broker acceptable to the
Company to promptly deliver to the Company the amount of sale or loan proceeds
to pay the exercise price. As determined by the Committee, in its sole
discretion, payment in full or in part may also be made in the form of
unrestricted Stock already owned by the optionee or, in the case of the exercise
of a Non-Qualified Stock Option or Restricted Stock subject to an award
hereunder (based, in each case, on the Fair Market Value of the Stock on the
date the option is exercised, as determined by the Committee); provided,
however, that, in the case of an Incentive Stock Option, the right to make a
payment in the form of already owned shares may be authorized only at the time
the option is granted, and provided further that in the event payment is made in
the form of shares of Restricted Stock, the optionee will receive a portion of
the option shares in the form of, and in an amount equal to, the Restricted
Stock award tendered as payment by the optionee. If the terms of an option so
permit, an optionee may elect to pay all or part of the option exercise price by
having the Company withhold from the shares of Stock that would otherwise be
issued upon exercise that number of shares of Stock having a Fair Market Value
equal to the aggregate option


                                        5
<PAGE>


exercise price for the shares with respect to which such election is made. No
shares of Stock shall be issued until full payment therefor has been made. An
optionee shall generally have the rights to dividends and other rights of a
shareholder with respect to shares subject to the option when the optionee has
given written notice of exercise, has paid in full for such shares, and, if
requested, has given the representation described in paragraph (a) of Section
10.

         (e) Non-transferability of Options. No Stock Option shall be
transferable by the optionee otherwise than by will or by the laws of descent
and distribution, and all Stock Options shall be exercisable, during the
optionee's lifetime, only by the optionee.

         (f) Termination by Death. If an optionee's employment by the Company
and any Subsidiary or Parent Corporation terminates by reason of death, the
Stock Option may thereafter be immediately exercised, to the extent then
exercisable (or on such accelerated basis as the Committee shall determine at or
after grant), by the legal representative of the estate or by the legatee of the
optionee under the will of the optionee, for a period of three years (or such
shorter period as the Committee shall specify at grant) from the date of such
death or until the expiration of the stated term of the option, whichever period
is shorter.

         (g) Termination by Reason of Disability. If an optionee's employment by
the Company and any Subsidiary or Parent Corporation terminates by reason of
Disability, any Stock Option held by such optionee may thereafter be exercised,
to the extent it was exercisable at the time of termination due to Disability
(or on such accelerated basis as the Committee shall determine at or after
grant), but may not be exercised after three years (or such shorter period as
the Committee shall specify at grant) from the date of such termination of
employment or the expiration of the stated term of the option, whichever period
is the shorter. In the event of termination of employment by reason of
Disability, if an Incentive Stock Option is exercised after the expiration of
the exercise periods that apply for purposes of Section 422A of the Code, the
option will thereafter be treated as a Non-Qualified Stock Option.

         (h) Termination by Reason of Retirement. If an optionee's employment by
the Company and any Subsidiary or Parent Corporation terminates by reason of
Retirement, any Stock Option held by such optionee may thereafter be exercised
to the extent it was exercisable at the time of such Retirement, but may not be
exercised after three years (or such shorter period as Committee shall specify
at grant) from the date of such termination of employment or the expiration of
the stated term of the option, whichever period is the shorter. In the event of
termination of employment by reason of Retirement, if an Incentive Stock Option
is exercised after the expiration of the exercise periods that apply for
purposes of Section 422A of the Code, the option will thereafter be treated as a
Non-Qualified Stock Option.

         (i) Other Termination. Unless otherwise determined by the Committee, if
an optionee's employment by the Company and any Subsidiary or Parent Corporation
terminates for any reason other than death, Disability or Retirement, the Stock
Option shall thereupon terminate, except that the option may be exercised to the
extent it was exercisable at such termination for the lesser of three


                                        6
<PAGE>


months or the balance of the option's term if the optionee is involuntarily
terminated without Cause by the Company and any Subsidiary or Parent
Corporation.

         (j) Annual Limit on Incentive Stock Options. The aggregate Fair Market
Value (determined as of the time the Option is granted) of the Common Stock with
respect to which an Incentive Stock Option under this Plan or any other plan of
the Company and any Subsidiary or Parent Corporation is exercisable for the
first time by an optionee during any calendar year shall not exceed $100,000.

         (k) Automatic Grant to Non-Employee Directors. Each individual who is
serving as a member of the Board and who is not an employee of the Company, any
Parent Corporation or any Subsidiary (a "Non-Employee Director") shall be
automatically awarded, on the date this paragraph is adopted by the Board as a
part of the Plan, a Non-Qualified Stock Option, which shall be fully vested, to
purchase 5,000 shares of the Company's Common Stock at an exercise price equal
to 100% of the Fair Market Value of the Common Stock on such date and which
expires five years after the date of grant. An individual who is first elected
or appointed or who is re-elected as a Non-Employee Director at any time
thereafter shall receive a similar automatic grant, at the time of election or
appointment or re-election to the Board, of a Non-Qualified Stock Option, which
shall be fully vested, to purchase 5,000 shares of the Company's Common Stock at
an exercise price equal to 100% of the Fair Market Value of the Common Stock on
such date and which expires five years after the date of grant.

         SECTION 6. Restricted Stock.

         (a) Administration. Shares of Restricted Stock may be issued either
alone or in addition to other awards granted under the Plan. The Committee shall
determine the officers and key employees of the Company and Subsidiaries to
whom, and the time or times at which, grants of Restricted Stock will be made,
the number of shares to be awarded, the time or times within which such awards
may be subject to forfeiture, and all other conditions of the awards. The
Committee may also condition the grant of Restricted Stock upon the attainment
of specified performance goals. The provisions of Restricted Stock awards need
not be the same with respect to each recipient.

         (b) Awards and Certificates. The prospective recipient of an award of
shares of Restricted Stock shall not have any rights with respect to such award,
unless and until such recipient has executed an agreement evidencing the award
and has delivered a fully executed copy thereof to the Company, and has
otherwise complied with the then applicable terms and conditions.

                  (i) Each participant shall be issued a stock certificate in
         respect of shares of Restricted Stock awarded under the Plan. Such
         certificate shall be registered in the name of the participant, and
         shall bear an appropriate legend referring to the terms, conditions,
         and restrictions applicable to such award, substantially in the
         following form:


                                        7
<PAGE>


                  "The transferability of this certificate and the shares of
                  stock represented hereby are subject to the terms and
                  conditions (including forfeiture) of The Insignia Systems,
                  Inc. 1990 Stock Plan and an Agreement entered into between the
                  registered owner and the Company. Copies of such Plan and
                  Agreement are on file in the offices of the Company."

                  (ii) The Committee shall require that the stock certificates
         evidencing such shares be held in custody by the Company until the
         restrictions thereon shall have lapsed, and that, as a condition of any
         Restricted Stock award, the participant shall have delivered a stock
         power, endorsed in blank, relating to the Stock covered by such award.

         (c) Restrictions and Conditions. The shares of Restricted Stock awarded
pursuant to the Plan shall be subject to the following restrictions and
conditions:

                  (i) Subject to the provisions of this Plan and the award
         agreement, during a period set by the Committee commencing with the
         date of such award (the "Restriction Period"), the participant shall
         not be permitted to sell, transfer, pledge or assign shares of
         Restricted Stock awarded under the Plan. Within these limits, the
         Committee may provide for the lapse of such restrictions in
         installments where deemed appropriate.

                  (ii) Except as provided in paragraph (c)(i) of this Section 6,
         the participant shall have, with respect to the shares of Restricted
         Stock, all of the rights of a shareholder of the Company, including the
         right to vote the shares and the right to receive any cash dividends.
         The Committee, in its sole discretion, may permit or require the
         payment of cash dividends to be deferred and, if the Committee so
         determines, reinvested in additional shares of Restricted Stock (to the
         extent shares are available under Section 3 and subject to paragraph
         (f) of Section 10). Certificates for shares of unrestricted Stock shall
         be delivered to the grantee promptly after, and only after, the period
         of forfeiture shall have expired without forfeiture in respect of such
         shares of Restricted Stock.

                  (iii) Subject to the provisions of the award agreement and
         paragraph (c)(iv) of this Section 6, upon termination of employment for
         any reason during the Restriction Period, all shares still subject to
         restriction shall be forfeited by the participant.

                  (iv) In the event of special hardship circumstances of a
         participant whose employment is terminated (other than for Cause),
         including death, Disability or Retirement, or in the event of an
         unforeseeable emergency of a participant still in service, the
         Committee may, in its sole discretion, when it finds that a waiver
         would be in the best interest of the Company, waive in whole or in part
         any or all remaining restrictions with respect to such participant's
         shares of Restricted Stock.


                                        8
<PAGE>


         SECTION 7. Transfer, Leave of Absence, etc.

         For purposes of the Plan, the following events shall not be deemed a
termination of employment:

         (a) a transfer of an employee from the Company to a Parent Corporation
or Subsidiary, or from a Parent Corporation or Subsidiary to the Company, or
from one Subsidiary to another;

         (b) a leave of absence, approved in writing by the Committee, for
military service or sickness, or for any other purpose approved by the Company
if the period of such leave does not exceed ninety (90) days (or such longer
period as the Committee may approve, in its sole discretion); and

         (c) a leave of absence in excess of ninety (90) days, approved in
writing by the Committee, but only if the employee's right to reemployment is
guaranteed either by a statute or by contract, and provided that, in the case of
any leave of absence, the employee returns to work within 30 days after the end
of such leave.

         SECTION 8. Amendments and Termination.

         The Board may amend, alter, or discontinue the Plan, but no amendment,
alteration, or discontinuation shall be made (i) which would impair the rights
of an optionee or participant under a Stock Option, Restricted Stock or other
Stock-based award theretofore granted, without the optionee's or participant's
consent, or (ii) which without the approval of the stockholders of the Company
would cause the Plan to no longer comply with Rule 16b-3 under the Securities
Exchange Act of 1934, Section 422A of the Code or any other regulatory
requirements.

         The Committee may amend the terms of any award or option theretofore
granted, prospectively or retroactively, but, subject to Section 3 above, no
such amendment shall impair the rights of any holder without his consent.
Without limiting the generality of the foregoing, the Committee (or if there is
no Committee, then the Board) shall have the authority to accelerate the vesting
of any or all outstanding options or awards in the event of any actual or
threatened change in control of the Company. The Committee may also substitute
new Stock Options for previously granted options, including previously granted
options having higher option prices.

         SECTION 9. Unfunded Status of Plan.

         The Plan is intended to constitute an "unfunded" plan for incentive and
deferred compensation. With respect to any payments not yet made to a
participant or optionee by the Company, nothing contained herein shall give any
such participant or optionee any rights that are greater than those of a general
creditor of the Company. In its sole discretion, the Committee may authorize the
creation of trusts or other arrangements to meet the obligations created under
the Plan


                                        9

to deliver Stock or payments in lieu of or with respect to awards hereunder,
provided, however, that the existence of such trusts or other arrangements is
consistent with the unfunded status of the Plan.

         SECTION 10. General Provisions.

         (a) The Committee may require each person purchasing shares pursuant to
a Stock Option under the Plan to represent to and agree with the Company in
writing that the optionee is acquiring the shares without a view to distribution
thereof. The certificates for such shares may include any legend which the
Committee deems appropriate to reflect any restrictions on transfer.

         All certificates for shares of Stock delivered under the Plan pursuant
to any Restricted Stock or other Stock-based awards shall be subject to such
stock-transfer orders and other restrictions as the Committee may deem advisable
under the rules, regulations, and other requirements of the Securities and
Exchange Commission, any stock exchange upon which the Stock is then listed, and
any applicable Federal or state securities laws, and the Committee may cause a
legend or legends to be put on any such certificates to make appropriate
reference to such restrictions.

         (b) Subject to paragraph (d) below, recipients of Restricted Stock and
other Stock-based awards under the Plan (other than Stock Options) are not
required to make any payment or provide consideration other than the rendering
of services.

         (c) Nothing contained in this Plan shall prevent the Board of Directors
from adopting other or additional compensation arrangements, subject to
stockholder approval if such approval is required; and such arrangements may be
either generally applicable or applicable only in specific cases. The adoption
of the Plan shall not confer upon any employee of the Company or any Subsidiary
any right to continued employment with the Company or a Subsidiary, as the case
may be, nor shall it interfere in any way with the right of the Company or a
Subsidiary to terminate the employment of any of its employees at any time.

         (d) Each participant shall, no later than the date as of which any part
of the value of an award first becomes includible as compensation in the gross
income of the participant for Federal income tax purposes, pay to the Company,
or make arrangements satisfactory to the Committee regarding payment of, any
Federal, state, or local taxes of any kind required by law to be withheld with
respect to the award. The obligations of the Company under the Plan shall be
conditional on such payment or arrangements and the Company and Subsidiaries
shall, to the extent permitted by law, have the right to deduct any such taxes
from any payment of any kind otherwise due to the participant. With respect to
any award under the Plan, if the terms of such award so permit, a participant
may elect by written notice to the Company to satisfy part or all of the
withholding tax requirements associated with the award by (i) authorizing the
Company to retain from the number of shares of Stock that would otherwise be
deliverable to the participant, or (ii) delivering to the Company from shares of
Stock already owned by the participant, that number of shares having an
aggregate Fair Market Value equal to part or all of the tax payable by the
participant under this


                                       10

Section 10(d). Any such election shall be in accordance with, and subject to,
applicable tax and securities laws, regulations and rulings.

         (e) At the time of grant, the Committee may provide in connection with
any grant made under this Plan that the shares of Stock received as a result of
such grant shall be subject to a repurchase right in favor of the Company,
pursuant to which the participant shall be required to offer to the Company upon
termination of employment for any reason any shares that the participant
acquired under the Plan, with the price being the then Fair Market Value of the
Stock or, in the case of a termination for Cause, an amount equal to the cash
consideration paid for the Stock, subject to such other terms and conditions as
the Committee may specify at the time of grant. The Committee may, at the time
of the grant of an award under the Plan, provide the Company with the right to
repurchase, or require the forfeiture of, shares of Stock acquired pursuant to
the Plan by any participant who, at any time within one year after termination
of employment with the Company, directly or indirectly competes with, or is
employed by a competitor of, the Company.

         (f) The reinvestment of dividends in additional Restricted Stock at the
time of any dividend payment shall only be permissible if the Committee (or the
Company's chief financial officer) certifies in writing that under Section 3
sufficient shares are available for such reinvestment (taking into account then
outstanding Stock Options and other Plan awards).

         SECTION 11. Effective Date of Plan.

         The Plan shall be effective on the date it is approved by a vote of the
holders of a majority of the Stock present and entitled to vote at a meeting of
the Company's shareholders.
