4.       ADMINISTRATION OF THE PLAN.

The Administrator of the Plan will be the Board of Directors, except to the
extent the Board of Directors delegates its authority to the Committee, in which
case the Committee shall be the Administrator. Following the date on which the
Common Stock is registered under the Securities and Exchange Act of 1934, as
amended (the "1934 Act"), the Plan is intended to comply in all respects with
Rule 16b-3 or its successors, promulgated pursuant to Section 16 of the 1934 Act
with respect to Participants who are subject to Section 16 of the 1934 Act, and
any provision in this Plan with respect to such persons contrary to Rule 16b-3
shall be deemed null and void to the extent permissible by law and deemed
appropriate by the Administrator. Subject to the provisions of the Plan, the
Administrator is authorized to:
             
        a.        Interpret the provisions of the Plan or of any Option or
                  Option Agreement and to make all rules and determinations
                  which it deems necessary or advisable for the administration
                  of the Plan;

        b.        Determine which employees of the Company or of an Affiliate
                  shall be designated as Key Employees and which of the Key
                  Employees, directors and consultants shall be granted Options;
         
        c.        Determine the number of Shares for which an Option or Options
                  shall be granted; and
        
        d.        Specify the terms and conditions upon which an Option or
                  Options may be granted;

provided, however, that all such interpretations, rules, determinations, terms
and conditions shall be made and prescribed in the context of preserving the tax
status under Section 422 of the Code of those Options which are designated as
ISOs. Subject to the foregoing, the interpretation and construction by the
Administrator of any provisions of the Plan or of any Option granted under it
shall be final, unless otherwise determined by the Board of Directors, if the
Administrator is the Committee.

5.       ELIGIBILITY FOR PARTICIPATION.

         The Administrator will, in its sole discretion, name the Participants
in the Plan, provided, however, that each Participant must be a Key Employee,
director or consultant of the Company or of an Affiliate at the time an Option
is granted. Members of the Board of Directors who are not employees of the
Company or of an Affiliate may receive options pursuant to Paragraph 6(A)(e) of
the Plan, but only pursuant thereto.



                                     - 4 -

Notwithstanding any of the foregoing provisions, the Administrator may authorize
the grant of an Option to a person not then an employee, director or consultant
of the Company or of an Affiliate. The actual grant of such Option, however,
shall be conditioned upon such person becoming eligible to become a Participant
at or prior to the time of the execution of the Option Agreement evidencing such
Option. ISOs may be granted only to Key Employees. Non-Qualified Options may be
granted to any Key Employee, director or consultant of the Company or an
Affiliate. The granting of any Option to any individual shall neither entitle
that individual to, nor disqualify him or her from, participation in any other
grant of Options.

6.       TERMS AND CONDITIONS OF OPTIONS.

         Each Option shall be set forth in writing in an Option Agreement, duly
executed by the Company and, to the extent required by law or requested by the
Company, by the Participant. The Administrator may provide that Options be
granted subject to such conditions as the Administrator may deem appropriate,
including, without limitation, subsequent approval by the shareholders of the
Company of this Plan or any amendments to this Plan. The Option Agreements shall
be subject to at least the following terms and conditions:
       
        A.        Non-Qualified Options: Each Option intended to be a
                  Non-Qualified Option shall be subject to the terms and

                  to the following minimum standards for any such Non-Qualified
                  Option:

                           by the Administrator but shall not be less than the
                           par value per share of Common Stock;
                      
                 b.        Number of Shares. Each Option Agreement shall state

                           be exercised, and may provide that the Option rights
                           accrue or become exercisable in installments over a
                           period of months or years, or upon the occurrence of
                           certain conditions or the attainment of stated goals
                           or events;

                 d.        Option Conditions. Exercise of any Option may be
                           conditioned upon the Participant's execution of a

                           Administrator providing for certain protections for
                           the Company and its other shareholders including
                           requirements that:

                                    legends noting any applicable restrictions.

                  

                 e.        Directors' Options. Each director of the Company who

                           February 1, 1997 and May 1, 1997). Any director

                           every six months, other than to comport with changes
                           in the Code, the Employee Retirement Income Security

                           Options granted pursuant to this Subparagraph.

         Except as otherwise provided in the pertinent Option Agreement, if a
director who received Options pursuant to this Subparagraph (e):

                          

                          i.        ceases to be a member of the Board of
                                    Directors for any reason other than death or
                                    Disability, any then unexercised Options
                                    granted to such director may be exercised by
                                    the director within a period of ninety (90)
                                    days after the date the director ceases to
                                    be a member of the Board of Directors, but
                                    only to the extent of the number of Shares
                                    with respect to which the Options are
                                    exercisable on the date the director ceases
                                    to be a member of the Board of Directors,
                                    and in no event later than the expiration
                                    date of the Option; or

                            

                         ii.        ceases to be a member of the Board of

                                    Disability, any then unexercised Options
                                    granted to such director may be exercised by
                                    the director (or by the Participant's
                                    personal representative, or Participant's
                                    Survivors in the event of death) within a
                                    period of one hundred eighty (180) days
                                    after 

                                     - 7 -
   8
                                    the date the director ceases to be a member
                                    of the Board of Directors, but only to the
                                    extent of the number of Shares with respect
                                    to which the Options are exercisable on the
                                    date the director ceases to be a member of
                                    the Board of Directors, and in no event
                                    later than the expiration date of the
                                    Option.

         B.       ISOs: Each Option intended to be an ISO shall be issued only
                  to a Key Employee and be subject to at least the following
                  terms and conditions, with such additional restrictions or
                  changes as the Administrator determines are appropriate but
                  not in conflict with Section 422 of the Code and relevant
                  regulations and rulings of the Internal Revenue Service:

                        

                  a.       Minimum standards. The ISO shall meet the minimum
                           standards required of Non-Qualified Options, as
                           described in Paragraph 6(A) above, except clauses (a)
                           and (e) thereunder.
                    
                  b.       Option Price. Immediately before the Option is
                           granted, if the Participant owns, directly or by
                           reason of the applicable attribution rules in Section
                           424(d) of the Code:

                                    Shares covered by each Option shall not be
                                    less than one hundred percent (100%) of the
                                    Fair Market Value per share of the Shares on
                                    the date of the grant of the Option.

                                    combined voting power of all classes of

                                    Affiliate, the Option price per share of the
                                    Shares covered by each Option shall not be
                                    less than one hundred ten percent (110%) of
                                    the said Fair Market Value on the date of
                                    grant.

                                    more than ten (10) years from the date of
                                    the grant or at such earlier time as the
                                    Option Agreement may provide.

                           ii.      More than ten percent (10%) of the total
                                    combined voting power of all classes of
                                    share capital of the Company or an
                                    Affiliate, each Option shall terminate not
                                    more than five (5) years from the date of
                                    the grant or at such earlier time as the
                                    Option Agreement may provide.

                      
                  d.       Limitation on Yearly Exercise. The Option Agreements
                           shall restrict the amount of Options which may be
                           exercisable in any calendar year (under this or any
                           other ISO plan of the Company or an Affiliate) so
                           that the aggregate Fair Market Value (determined at
                           the time each ISO is granted) of the stock with
                           respect to which ISOs are exercisable for the first
                           time by the Participant in any calendar year does not
                           exceed one hundred thousand dollars ($100,000),
                           provided that this Subparagraph (d) shall have no
                           force or effect if its inclusion in the Plan is not
                           necessary for Options issued as ISOs to qualify as
                           ISOs pursuant to Section 422(d) of the Code.
                 
                  e.       Limitation on Grant of ISOs: No ISOs shall be granted
                           after March 4, 2006.

7.       EXERCISE OF OPTION AND ISSUE OF SHARES.

         An Option (or any part or installment thereof) shall be exercised by
giving written notice to the Company at its principal office address, together
with provision for payment of the full purchase price in accordance with this
Paragraph for the Shares as to which such Option is being exercised, and upon
compliance with any other condition(s) set forth in the Option Agreement. Such
written notice shall be signed by the person exercising the Option, shall state
the number of Shares with respect to which the Option is being exercised and
shall contain any representation required by the Plan or the Option Agreement.
Payment of the purchase price for the Shares as to which such Option is being
exercised shall be made (a) in United States dollars in cash or by check, or (b)
at the discretion of the Administrator, through delivery of shares of Common
Stock having a fair market value equal as of the date of the exercise to the
cash exercise price of the Option, determined in good faith by the
Administrator, or (c) at the discretion of the Administrator, by delivery of the
grantee's personal recourse note bearing interest payable not less than annually
at no less than 100% of the applicable Federal rate, as defined in Section
1274(d) of the Code, or (d) at the discretion of the Administrator, in
accordance with a cashless exercise program established with a securities
brokerage firm, and approved by the Administrator or

                                     - 9 -
   10
(e) at the discretion of the Administrator, by any combination of (a), (b), (c)
and (d) above. Notwithstanding the foregoing, the Administrator shall accept
only such payment on exercise of an ISO as is permitted by Section 422 of the
Code.

         The Company shall then reasonably promptly deliver the Shares as to
which such Option was exercised to the Participant (or to the Participant's
Survivors, as the case may be). In determining what constitutes "reasonably
promptly," it is expressly understood that the delivery of the Shares may be
delayed by the Company in order to comply with any law or regulation which
requires the Company to take any action with respect to the Shares prior to
their issuance. The Shares shall, upon delivery, be evidenced by an appropriate
certificate or certificates for fully paid, non-assessable Shares.

         In lieu of permitting a Participant to obtain Common Stock pursuant to
the exercise of an Option, the Company may, in its sole discretion, pay to the
Participant an amount equal to the Appreciated Value multiplied by the number of
shares of Common Stock that the Participant is entitled to upon the exercise of
an Option (the "Appreciated Amount"). The Appreciated Amount shall be payable to
the Participant within fifteen (15) days of receipt by the Company of the notice
from the Participant that the Participant intends to exercise the Option.
"Appreciated Value" shall mean the amount by which (i) the per share Fair Market
Value on the date of exercise of the Option, exceeds (ii) the option price per
share set forth in the related Option Agreement.

         The Administrator shall have the right to accelerate the date of
exercise of any installment of any Option; provided that the Administrator shall
not accelerate the exercise date of any installment of any Option granted to any
Key Employee as an ISO (and not previously converted into a Non-Qualified Option
pursuant to Paragraph 19) if such acceleration would violate the annual vesting
limitation contained in Section 422(d) of the Code, as described in Paragraph
6(A)(d).

         The Administrator may, in its discretion, amend any term or condition
of an outstanding Option provided (i) such term or condition as amended is
permitted by the Plan, (ii) any such amendment shall be made only with the
consent of the Participant to whom the Option was granted, or in the event of
the death of the Participant, the Participant's Survivors, if the amendment is
adverse to the Participant, (iii) any such amendment of any ISO shall be made
only after the Administrator, after consulting the counsel for the Company,
determines whether such amendment would constitute a "modification" of any
Option which is an ISO (as that term is defined in Section 424(h) of the Code)
or would cause any adverse tax consequences for the holders of such ISO, and
(iv) with respect to any Option held by any Participant who is subject to the
provisions of Section 16(a) of the 1934 Act, 


                                     - 10 -
   11
any such amendment shall be made only after the Administrator, after consulting
with counsel for the Company, determines whether such amendment would constitute
the grant of a new Option.

8.       RIGHTS AS A SHAREHOLDER.

         No Participant to whom an Option has been granted shall have rights as
a shareholder with respect to any Shares covered by such Option, except after
due exercise of the Option and tender of the full purchase price for the Shares
being purchased pursuant to such exercise and registration of the Shares in the
Company's share register in the name of the Participant.

9.       ASSIGNABILITY AND TRANSFERABILITY OF OPTIONS.

         By its terms, an Option granted to a Participant shall not be
transferable by the Participant other than by will or by the laws of descent and
distribution or pursuant to a qualified domestic relations order as defined by
the Code or Title I of the Employee Retirement Income Security Act or the rules
thereunder, provided, however, that the designation of a beneficiary of an
Option by a Participant shall not be deemed a transfer prohibited by this
Paragraph. Except as provided in the preceding sentence, an Option shall be
exercisable, during the Participant's lifetime, only by such Participant (or by
his or her legal representative) and shall not be assigned, pledged or
hypothecated in any way (whether by operation of law or otherwise) and shall not
be subject to execution, attachment or similar process. Any attempted transfer,
assignment, pledge, hypothecation or other disposition of any Option or of any
rights granted thereunder contrary to the provisions of this Plan, or the levy
of any attachment or similar process upon an Option, shall be null and void.

10.      EFFECT OF TERMINATION OF SERVICE OTHER THAN "FOR CAUSE".

         Except as otherwise provided in the pertinent Option Agreement, in the
event of a termination of service (whether as an employee, director or
consultant) with the Company or an Affiliate before the Participant has
exercised all Options, the following rules apply:

         a.       A Participant who ceases to be an employee, director or
                  consultant of the Company or of an Affiliate (for any reason
                  other than termination "for cause", Disability, or death for
                  which events there are special rules in Paragraphs 11, 12, and
                  13, respectively), may exercise any Option granted to him or
                  her to the extent that the Option is exercisable on the date
                  of such termination 

                                     - 11 -
   12
                  of service, but only within such term as the Administrator has
                  designated in the pertinent Option Agreement.

         b.       In no event may an Option Agreement provide, if the Option is
                  intended to be an ISO, that the time for exercise be later
                  than three (3) months after the Participant's termination of
                  employment.

         c.       The provisions of this Paragraph, and not the provisions of
                  Paragraph 12 or 13, shall apply to a Participant who
                  subsequently becomes disabled or dies after the termination of
                  employment, director status or consultancy, provided, however,
                  in the case of a Participant's death within three (3) months
                  after the termination of employment, director status or
                  consulting, the Participant's Survivors may exercise the
                  Option within one (1) year after the date of the Participant's
                  death, but in no event after the date of expiration of the
                  term of the Option.

         d.       Notwithstanding anything herein to the contrary, if subsequent
                  to a Participant's termination of employment, termination of
                  director status or termination of consultancy, but prior to
                  the exercise of an Option, the Board of Directors determines
                  that, either prior or subsequent to the Participant's
                  termination, the Participant engaged in conduct which would
                  constitute "cause", then such Participant shall forthwith
                  cease to have any right to exercise any Option.

         e.       A Participant to whom an Option has been granted under the
                  Plan who is absent from work with the Company or with an
                  Affiliate because of temporary disability (any disability
                  other than a permanent and total Disability as defined in
                  Paragraph 1 hereof), or who is on leave of absence for any
                  purpose, shall not, during the period of any such absence, be
                  deemed, by virtue of such absence alone, to have terminated
                  such Participant's employment, director status or consultancy
                  with the Company or with an Affiliate, except as the
                  Administrator may otherwise expressly provide.

         f.       Options granted under the Plan shall not be affected by any
                  change of employment or other service within or among the
                  Company and any Affiliates, so long as the Participant
                  continues to be an employee, director or consultant of the
                  Company or any Affiliate, provided, however, if a
                  Participant's employment by either the Company or an Affiliate
                  should cease (other than to

                                     - 12 -
   13
                  become an employee of an Affiliate or the Company), such
                  termination shall affect the Participant's rights under any
                  Option granted to such Participant in accordance with the
                  terms of the Plan and the pertinent Option Agreement.

11.      EFFECT OF TERMINATION OF SERVICE "FOR CAUSE".

         Except as otherwise provided in the pertinent Option Agreement, the
following rules apply if the Participant's service (whether as an employee,
director or consultant) with the Company or an Affiliate is terminated "for
cause" prior to the time that all of his or her outstanding Options have been
exercised:

         a.       All outstanding and unexercised Options as of the date the
                  Participant is notified his or her service is terminated "for
                  cause" will immediately be forfeited, unless the Option
                  Agreement provides otherwise.

         b.       For purposes of this Paragraph, "cause" shall include (and is
                  not limited to) dishonesty with respect to the Company or any
                  Affiliate, insubordination, substantial malfeasance or
                  non-feasance of duty, unauthorized disclosure of confidential
                  information, and conduct substantially prejudicial to the
                  business of the Company or any Affiliate. The determination of
                  the Administrator as to the existence of cause will be
                  conclusive on the Participant and the Company.

         c.       "Cause" is not limited to events which have occurred prior to
                  a Participant's termination of service, nor is it necessary
                  that the Administrator's finding of "cause" occur prior to
                  termination. If the Administrator determines, subsequent to a
                  Participant's termination of service but prior to the exercise
                  of an Option, that either prior or subsequent to the
                  Participant's termination the Participant engaged in conduct
                  which would constitute "cause", then the right to exercise any
                  Option is forfeited.

         d.       Any definition in an agreement between the Participant and the
                  Company or an Affiliate, which contains a conflicting
                  definition of "cause" for termination and which is in effect
                  at the time of such termination, shall supersede the
                  definition in this Plan with respect to such Participant.

12.      EFFECT OF TERMINATION OF SERVICE FOR DISABILITY.

         Except as otherwise provided in the pertinent Option Agreement, a
Participant who ceases to be an employee, director or consultant of the Company
or of an Affiliate by reason of Disability may exercise any Option granted to
such Participant:
            
         a.       To the extent exercisable but not exercised on the date of
                  Disability; and

           
         b.       In the event rights to exercise the Option accrue
                  periodically, to the extent of a pro rata portion of any
                  additional rights as would have accrued had the Participant
                  not become Disabled prior to the end of the accrual period
                  which next ends following the date of Disability. The
                  proration shall be based upon the number of days of such
                  accrual period prior to the date of Disability.

         A Disabled Participant may exercise such rights only within a period of
not more than one (1) year after the date that the Participant became Disabled,
notwithstanding that the Participant might have been able to exercise the Option
as to some or all of the Shares on a later date if he or she had not become
disabled and had continued to be an employee, director or consultant or, if
earlier, within the originally prescribed term of the Option.

         The Administrator shall make the determination both of whether
Disability has occurred and the date of its occurrence (unless a procedure for
such determination is set forth in another agreement between the Company and
such Participant, in which case such procedure shall be used for such
determination). If requested, the Participant shall be examined by a physician
selected or approved by the Administrator, the cost of which examination shall
be paid for by the Company.

13.      EFFECT OF DEATH WHILE AN EMPLOYEE, DIRECTOR OR CONSULTANT.

         Except as otherwise provided in the pertinent Option Agreement, in the
event of the death of a Participant to whom an Option has been granted while the
Participant is an employee, director or consultant of the Company or of an
Affiliate, such Option may be exercised by the Participant's Survivors:

               

         a.       To the extent exercisable but not exercised on the date of
                  death; and

         b.       In the event rights to exercise the Option accrue
                  periodically, to the extent of a pro rata portion of any
                  additional rights which would have accrued had the Participant
                  not died prior to the end of the accrual 

                                     - 14 -
   15
                  period which next ends following the date of death. The
                  proration shall be based upon the number of days of such
                  accrual period prior to the Participant's death.

         If the Participant's Survivors wish to exercise the Option, they must
take all necessary steps to exercise the Option within one (1) year after the
date of death of such Participant, notwithstanding that the decedent might have
been able to exercise the Option as to some or all of the Shares on a later date
if he or she had not died and had continued to be an employee, director or
consultant or, if earlier, within the originally prescribed term of the Option.

14.      PURCHASE FOR INVESTMENT.

         Unless the offering and sale of the Shares to be issued upon the
particular exercise of an Option shall have been effectively registered under
the Securities Act of 1933, as now in force or hereafter amended (the "1933
Act"), the Company shall be under no obligation to issue the Shares covered by
such exercise unless and until the following conditions have been fulfilled:

         a.       The person(s) who exercise such Option shall warrant to the
                  Company, prior to the receipt of such Shares, that such
                  person(s) are acquiring such Shares for their own respective
                  accounts, for investment, and not with a view to, or for sale
                  in connection with, the distribution of any such Shares, in
                  which event the person(s) acquiring such Shares shall be bound
                  by the provisions of the following legend which shall be
                  endorsed upon the certificate(s) evidencing their Shares
                  issued pursuant to such exercise or such grant:

                           "The shares represented by this certificate have been
                           taken for investment and they may not be sold or
                           otherwise transferred by any person, including a
                           pledgee, unless (1) either (a) a Registration
                           Statement with respect to such shares shall be
                           effective under the Securities Act of 1933, as
                           amended, or (b) the Company shall have received an
                           opinion of counsel satisfactory to it that an
                           exemption from registration under such Act is then
                           available, and (2) there shall have been compliance
                           with all applicable state securities laws.

         b.       The Company shall have received an opinion of its counsel that
                  the Shares may be issued upon such particular exercise in
                  compliance with the 1933 Act without registration thereunder.

                                     - 15 -
   16
         The Company may delay issuance of the Shares until completion of any
action or obtaining of any consent which the Company deems necessary under any
applicable law (including, without limitation, state securities or "blue sky"
laws).

15.      DISSOLUTION OR LIQUIDATION OF THE COMPANY.

         Upon the dissolution or liquidation of the Company, all Options granted
under this Plan which as of such date shall not have been exercised will
terminate and become null and void; provided, however, that if the rights of a
Participant or a Participant's Survivors have not otherwise terminated and
expired, the Participant or the Participant's Survivors will have the right
immediately prior to such dissolution or liquidation to exercise any Option to
the extent that the Option is exercisable as of the date immediately prior to
such dissolution or liquidation.

16.      ADJUSTMENTS.

         Upon the occurrence of any of the following events, a Participant's
rights with respect to any Option granted to him or her hereunder which have not
previously been exercised in full shall be adjusted as hereinafter provided,
unless otherwise specifically provided in the written agreement between the
Participant and the Company relating to such Option:

         A. Stock Dividends and Stock Splits. If the shares of Common Stock
shall be subdivided or combined into a greater or smaller number of shares or if
the Company shall issue any shares of Common Stock as a stock dividend on its
outstanding Common Stock, the number of shares of Common Stock deliverable upon
the exercise of such Option shall be appropriately increased or decreased
proportionately, and appropriate adjustments shall be made in the purchase price
per share to reflect such subdivision, combination or stock dividend. The number
of Shares subject to options to be granted to directors pursuant to Paragraph
6(A)(e) shall also be proportionately adjusted upon the occurrence of such
events.

         B. Consolidations or Mergers. If the Company is to be consolidated with
or acquired by another entity in a merger, sale of all or substantially all of
the Company's assets or otherwise (an "Acquisition"), the Administrator or the
board of directors of any entity assuming the obligations of the Company
hereunder (the "Successor Board"), shall, as to outstanding Options, either (i)
make appropriate provision for the continuation of such Options by substituting
on an equitable basis for the Shares then subject to such Options either the
consideration payable with respect to the outstanding shares of Common Stock in
connection 

                                     - 16 -
   17
with the Acquisition or securities of any successor or acquiring
entity; or (ii) upon written notice to the Participants, provide that all
Options must be exercised (either to the extent then exercisable or, at the
discretion of the Administrator, all Options being made fully exercisable for
purposes of this Subparagraph), within a specified number of days of the date of
such notice, at the end of which period the Options shall terminate; or (iii)
terminate all Options in exchange for a cash payment equal to the excess of the
Fair Market Value of the shares subject to such Options (either to the extent
then exercisable or, at the discretion of the Administrator, all Options being
made fully exercisable for purposes of this Subparagraph) over the exercise
price thereof.

         C. Recapitalization or Reorganization. In the event of a
recapitalization or reorganization of the Company (other than a transaction
described in Subparagraph B above) pursuant to which securities of the Company
or of another corporation are issued with respect to the outstanding shares of
Common Stock, a Participant upon exercising an Option shall be entitled to
receive for the purchase price paid upon such exercise the securities he or she
would have received if he or she had exercised such Option prior to such
recapitalization or reorganization.

         D. Modification of ISOs. Notwithstanding the foregoing, any adjustments
made pursuant to Subparagraph A, B or C with respect to ISOs shall be made only
after the Administrator, after consulting with counsel for the Company,
determines whether such adjustments would constitute a "modification" of such
ISOs (as that term is defined in Section 424(h) of the Code) or would cause any
adverse tax consequences for the holders of such ISOs. If the Administrator
determines that such adjustments made with respect to ISOs would constitute a
modification of such ISOs, it may refrain from making such adjustments, unless
the holder of an ISO specifically requests in writing that such adjustment be
made and such writing indicates that the holder has full knowledge of the
consequences of such "modification" on his or her income tax treatment with
respect to the ISO.

17.      ISSUANCES OF SECURITIES.

         Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares subject to Options. Except as
expressly provided herein, no adjustments shall be made for dividends paid in
cash or in property (including without limitation, securities) of the Company.


                                     - 17 -
   18
18.      FRACTIONAL SHARES.

         No fractional share shall be issued under the Plan and the person
exercising such right shall receive from the Company cash in lieu of such
fractional share equal to the Fair Market Value thereof.

19.      CONVERSION OF ISOs INTO NON-QUALIFIED OPTIONS:
         TERMINATION OF ISOs.

         The Administrator, at the written request of any Participant, may in
its discretion take such actions as may be necessary to convert such
Participant's ISOs (or any portions thereof) that have not been exercised on the
date of conversion into Non-Qualified Options at any time prior to the
expiration of such ISOs, regardless of whether the Participant is an employee of
the Company or an Affiliate at the time of such conversion. Such actions may
include, but not be limited to, extending the exercise period or reducing the
exercise price of the appropriate installments of such Options. At the time of
such conversion, the Administrator (with the consent of the Participant) may
impose such conditions on the exercise of the resulting Non-Qualified Options as
the Administrator in its discretion may determine, provided that such conditions
shall not be inconsistent with this Plan. Nothing in the Plan shall be deemed to
give any Participant the right to have such Participant's ISO's converted into
Non-Qualified Options, and no such conversion shall occur until and unless the
Administrator takes appropriate action. The Administrator, with the consent of
the Participant, may also terminate any portion of any ISO that has not been
exercised at the time of such termination.

20.      WITHHOLDING.

         In the event that any federal, state, or local income taxes, employment
taxes, Federal Insurance Contributions Act ("F.I.C.A.") withholdings or other
amounts are required by applicable law or governmental regulation to be withheld
from the Option holder's salary, wages or other remuneration in connection with
the exercise of an Option or a Disqualifying Disposition (as defined in
Paragraph 21), the Option holder shall advance in cash to the Company, or to any
Affiliate of the Company which employs or employed the Option holder, the amount
of such withholdings unless a different withholding arrangement, including the
use of shares of the Company's Common Stock, is authorized by the Administrator
(and permitted by law), provided, however, that with respect to persons subject
to Section 16 of the 1934 Act, any such withholding arrangement shall be in
compliance with any applicable provisions of Rule 16b-3 promulgated under
Section 16 of the 1934 Act. For purposes hereof, the fair market value of


                                     - 18 -
   19
the shares withheld for purposes of payroll withholding shall be determined in
the manner provided in Paragraph 1 above, as of the most recent practicable date
prior to the date of exercise. If the fair market value of the shares withheld
is less than the amount of payroll withholdings required, the Option holder may
be required to advance the difference in cash to the Company or the Affiliate
employer. The Administrator in its discretion may condition the exercise of an
Option for less than the then Fair Market Value on the Participant's payment of
such additional withholding.

21.      NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION.

         Each Key Employee who receives an ISO must agree to notify the Company
in writing immediately after the Key Employee makes a Disqualifying Disposition
of any shares acquired pursuant to the exercise of an ISO. A Disqualifying
Disposition is any disposition (including any sale) of such shares before the
later of (a) two years after the date the Key Employee was granted the ISO, or
(b) one year after the date the Key Employee acquired shares by exercising the
ISO. If the Key Employee has died before such stock is sold, these holding
period requirements do not apply and no Disqualifying Disposition can occur
thereafter.

22.      TERMINATION OF THE PLAN.

         The Plan will terminate on March 4, 2006. The Plan may be terminated at
an earlier date by vote of the shareholders of the Company; provided, however,
that any such earlier termination will not affect any Options granted or Option
Agreements executed prior to the effective date of such termination.

23.      AMENDMENT OF THE PLAN AND AGREEMENTS.

         The Plan may be amended by the shareholders of the Company. The Plan
may also be amended by the Administrator, including, without limitation, to the
extent necessary to qualify any or all outstanding Options granted under the
Plan or Options to be granted under the Plan for favorable federal income tax
treatment (including deferral of taxation upon exercise) as may be afforded
incentive stock options under Section 422 of the Code, to the extent necessary
to ensure the qualification of the Plan under Rule 16b-3, at such time, if any,
as the Company has a class of stock registered pursuant to Section 12 of the
1934 Act, and to the extent necessary to qualify the shares issuable upon
exercise of any outstanding Options granted, or Options to be granted, under the
Plan for listing on any national securities exchange or quotation in any
national automated quotation system of securities dealers. Any amendment
approved by the Administrator 


                                     - 19 -
   20
which is of a scope that requires shareholder approval in order to ensure
favorable federal income tax treatment for any incentive stock options or
requires shareholder approval in order to ensure the compliance of the Plan with
Rule 16b-3 at such time, if any, as the Company has a class of stock registered
pursuant to Section 12 of the 1934 Act, shall be subject to obtaining such
shareholder approval. Any modification or amendment of the Plan shall not,
without the consent of a Participant, adversely affect his or her rights under
an Option previously granted to him or her. With the consent of the Participant
affected, the Administrator may amend outstanding Option Agreements in a manner
which may be adverse to the Participant but which is not inconsistent with the
Plan. In the discretion of the Administrator, outstanding Option Agreements may
be amended by the Administrator in a manner which is not adverse to the
Participant.

24.      EMPLOYMENT OR OTHER RELATIONSHIP.

         Nothing in this Plan or any Option Agreement shall be deemed to prevent
the Company or an Affiliate from terminating the employment, consultancy or
director status of a Participant, nor to prevent a Participant from terminating
his or her own employment, consultancy or director status or to give any
Participant a right to be retained in employment or other service by the Company
or any Affiliate for any period of time.

25.      GOVERNING LAW.

         This Plan shall be construed and enforced in accordance with the law of
The Commonwealth of Massachusetts.
