                                                                    Exhibit 10.1

                            ON TECHNOLOGY CORPORATION

                          2002 EMPLOYEE AND CONSULTANT
                         STOCK OPTION AND INCENTIVE PLAN

1.   Purpose.

     The purpose of this plan (the "Plan") is to secure for ON Technology
Corporation (the "Company") and its shareholders the benefits arising from
capital stock ownership by employees and directors of and advisory committee
members of and consultants to the Company and its subsidiary corporations who
are expected to contribute to the Company's future growth and success. Except
where the context otherwise requires, the term "Company" shall include the
parent and all subsidiaries of the Company as defined in Sections 424(e) and
424(f) of the Internal Revenue Code of 1986, as amended (the "Code"). The Plan
contemplates the issuance of stock options and restricted stock.

2.   Administration of Plan.

     (a) Administration. The Plan will be administered by the Board of Directors
of the Company, whose construction and interpretation of the terms and
provisions of the Plan shall be final and conclusive. The Board of Directors may
in its sole discretion grant options to purchase shares of the Company's Common
Stock and issue shares upon exercise of such options as provided in the Plan or
issue shares of common stock in the Company pursuant to certain restrictions as
provided in the Plan. The Board shall have authority, subject to the express
provisions of the Plan, to construe the respective option agreements, stock
restriction agreements and the Plan; to prescribe, amend and rescind rules and
regulations relating to the Plan; to determine the terms and provisions of the
respective option and stock restriction agreements, which need not be identical;
and to make all other determinations in the judgment of the Board of Directors
necessary or desirable for the administration of the Plan. The Board of
Directors may correct any defect or supply any omission or reconcile any
inconsistency in the Plan or in any option or stock restriction agreement in the
manner and to the extent it shall deem expedient to carry the Plan into effect
and it shall be the sole and final judge of such expediency. No director shall
be liable for any action or determination made in good faith. The Board of
Directors may, to the full extent permitted by law, delegate any or all of its
powers under the Plan to a committee (the "Committee") appointed by the Board of
Directors, and if the Committee is so appointed all references to the Board of
Directors in the Plan shall mean and relate to such Committee.

     (b) Applicability of Rule 16b-3. Those provisions of the Plan which make
express reference to Rule 16b-3 promulgated under the Securities Exchange Act of
1934 (the "Exchange Act"), or any successor rule ("Rule 16b-3"), or which are
required in order for certain option transactions to qualify for an exemption
under Rule 16b-3, shall apply only to such persons as are required to file
reports under Section 16(a) of the Exchange Act (a "Reporting Person").

                                  Page 1 of 27

<PAGE>

     (c)  Board Discretion. The terms of each Restricted Stock Award and each
option agreement need not be identical, and the Board need not treat
Participants or optionees uniformly.

3.   Options and Restricted Stock.

     (a)  Types of Options. Options granted pursuant to the Plan shall be
authorized by action of the Board of Directors of the Company (or a Committee
designated by the Board of Directors) and may be either incentive stock options
("Incentive Stock Options") meeting the requirements of Section 422 of the Code
or non-statutory options which are not intended to meet the requirements of
Section 422 of the Code ("Non-Statutory Options" and, together with Incentive
Stock Options, "Options").

     (b)  Eligibility for Option Grants. The persons eligible to receive grants
of stock options are as follows:

          (i)   Incentive Stock Options. Incentive Stock Options shall be
granted only to persons who are, at the time of grant, employees (including
officers, directors and advisory committee members who are employees) of the
Company. No person shall be granted any Incentive Stock Option under the Plan
who, at the time such option is granted, owns, directly or indirectly, stock
possessing more than 10% of the total combined voting power of all classes of
stock of the Company, unless the requirements of paragraph (b) of Section 11 are
satisfied. The attribution of stock ownership provisions of Section 424(d) of
the Code, and any successor provisions thereto, shall be applied in determining
the shares of stock owned by a person for purposes of applying the foregoing
percentage limitation. A person who has been granted an option may, if he or she
is otherwise eligible, be granted an additional option or options if the Board
of Directors shall so determine.

          (ii)  Non-Statutory Options. Non-Statutory options shall be granted
only to persons who are, at the time of grant, employees (including officers,
directors and advisory committee members who are employees) or directors of or
advisory committee members of or consultants to the Company. A person who has
been granted an option may, if he or she is otherwise eligible, be granted an
additional option or options if the Board of Directors shall so determine.

          (iii) Grant of Options to Officers and Directors. From and after the
registration of the Common Stock of the Company under Section 12 of the
Securities Exchange Act of 1934 (the "Exchange Act"), the selection of an
officer or director as a participant in the plan and the timing, price and
number of shares for which an option or options may be granted to such officer
or director shall be determined either (i) by the Board of Directors, if all of
the directors shall be "disinterested persons" (as hereinafter defined) or (ii)
by, or only in accordance with, the recommendations of a committee of two or
more persons having full authority to act in the matter, of which all members
shall be "disinterested persons." For the purposes of the Plan, a director or
member of such committee shall be deemed to be "disinterested" only if such
person qualifies as a "disinterested person" within the meaning of paragraph
(c)(2) of Rule 16b-3 under the Exchange Act (or any successor rule), as such
term is interpreted from time to time.

                                  Page 2 of 27

<PAGE>

     (c) Conversion to Restricted Stock. The Board, in its discretion, may
choose, in any grant of an option or options under this Plan, to permit the
holder thereof to accelerate such option and convert such option to a purchase
of restricted stock as described in Section 3 below.

     (d) Restricted Stock. The Board may in its sole discretion grant restricted
stock awards or permit the acceleration and conversion of any option (each a
"Restricted Stock Award") to any employee, director, advisory committee member
or consultant of the Company (each such person a "Participant") to acquire
shares of Common Stock, subject to (i) delivery to the Company by the
Participant of a check in an amount equal to the purchase price of the shares
(which may not be less than the par value per share) and (ii) delivery to the
Company by the Participant of a written stock restriction agreement evidencing
the terms governing such Restricted Stock Award.

     (e) Terms and Conditions of Restricted Stock. The Board shall determine the
terms and conditions of any such Restricted Stock Award. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). After the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or, if the Participant has died, to the
beneficiary designated by a Participant, in a manner determined by the Board, to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

4.   Stock Subject to Plan.

     Subject to adjustment as provided in Section 15 below, the maximum number
of shares of Common Stock of the Company which may be issued and sold under the
Plan is 1,600,000 shares, all of which shares may be issued and sold pursuant to
Incentive Stock Options granted under the Plan, non-statutory options under the
Plan or Restricted Stock Awards under the Plan. Such shares may be authorized
and unissued shares or may be shares issued and thereafter acquired by the
Company. If an option granted under the Plan shall expire or terminate for any
reason without having been exercised in full, the unpurchased shares subject to
such option shall again be available for subsequent option grants under the
Plan. Shares of Common Stock repurchased by the Company under the terms of a
Restricted Stock Award shall again be available for subsequent option or
restricted stock grants under the Plan.

5.   Forms of Option Agreements and Stock Restriction Agreements.

     As a condition to the grant of an option under the Plan, each recipient of
an option shall execute an option agreement in such form not inconsistent with
the Plan as may be specified by the Board of Directors. Each option agreement
shall state whether the options granted thereby are Incentive Stock Options or
non-statutory options. As a condition to the purchase of shares pursuant to the
grant of a Restricted Stock Award, each recipient of a Restricted Stock Award
shall execute a stock restriction agreement in such form not inconsistent with
the Plan as may be specified by the Board of Directors and which shall include
the right of the Company to repurchase all or part of

                                  Page 3 of 27

<PAGE>

such shares at their issue price or other stated or formula price from the
Participant in the event that conditions specified by the Board in the
applicable Restricted Stock Award are not satisfied prior to the end of the
applicable restriction period or periods established by the Board for such
Restricted Stock Award.

6.   Purchase Price.

     (a) General. The purchase price per share of stock deliverable upon the
exercise of an option or pursuant to the grant of a Restricted Stock Award shall
be determined by the Board of Directors, provided, however, that (i) in the case
of an Incentive Stock Option, the exercise price shall not be less than 100% of
the fair market value of such stock, as determined by the Board of Directors, at
the time of grant of such option (or less than 110% of such fair market value in
the case of options described in paragraph (b) of Section 11); (ii) in the case
of a non-statutory option, the exercise price shall be determined in the sole
discretion of the Board of Directors, at the time of grant of such option; and
(iii) in the case of a Restricted Stock Award, the purchase price may not be
less that the par value of such stock.

     (b) Payment of Purchase Price. Options and Restricted Stock Awards granted
under the Plan may provide for the payment of the exercise price by delivery of
cash or a check to the order of the Company in an amount equal to the exercise
price of such options or purchase price for such restricted stock, or, to the
extent provided in the applicable option agreement or otherwise approved by the
Board of Directors, by delivery to the Company of shares of Common Stock of the
Company already owned by the optionee for at least six months and having a fair
market value equal in amount to the exercise price of the options being
exercised, or by any combination of such methods of payment. If payment of an
option exercise price is through shares already held by such optionee, such
shares to be tendered in payment may not be shares acquired upon the earlier
exercise of any incentive stock option unless the optionee has held such shares
until at least two years after the date of grant of such incentive stock option
or one year after the exercise of such incentive stock option. The fair market
value of any shares of the Company's Common Stock which may be delivered upon
exercise of an option shall be determined in accordance with the terms of the
applicable option agreement.

7.   Option Period.

     Each option and all rights thereunder shall expire on such date as the
Board of Directors shall determine, but, in the case of Incentive Stock Options,
in no event after the expiration of ten years from the day on which the option
is granted (or five years in the case of options described in paragraph (b) of
Section 11) and, in the case of non-statutory options, in no event after the
expiration of ten years plus 30 days from the day on which the option is
granted, and in either case, shall be subject to earlier termination as provided
in the Plan.

8.   Exercise of Options.

     Each option granted under the Plan shall be exercisable either in full or
in installments at such time or times and during such period as shall be set
forth in the agreement evidencing such option, subject to the provisions of
Section 7 above.

                                  Page 4 of 27

<PAGE>

9.   Non-transferability.

     (a)  Options. No option granted under the Plan shall be assignable or
transferable by the person to whom it is granted, either voluntarily or by
operation of law, except by will or the laws of descent and distribution or
pursuant to a qualified domestic relations order (as defined in the Code) or
Title I of the Employee Retirement Income Security Act, or the rules thereunder.
During the life of the optionee, the option shall be exercisable only by such
person.

     (b)  Restricted Stock. Except as the Board may otherwise determine or
provide in a Restricted Stock Award, Restricted Stock Awards shall not be sold,
assigned, transferred, pledged or otherwise encumbered by the person to whom
they are granted, either voluntarily or by operation of law, except by will or
the laws of descent and distribution, and, during the life of the Participant,
shall be exercisable only by the Participant. References to a Participant, to
the extent relevant in the context, shall include references to authorized
transferees.

10.  Effect of Termination of Employment.

     (a)  Options. No incentive stock option may be exercised unless, at the
time of such exercise, the optionee is, and has been continuously since the date
of grant of his or her option, employed by the Company, except that if and to
the extent the option agreement or instrument so provides:

          (i)   the option may be exercised within the period of three months
          after the date the optionee ceases to be an employee (other than by
          reason of death or disability) of the Company (or within such lesser
          period as may be specified in the applicable option agreement);

          (ii)  if the optionee dies while in the employ of the Company, or
          within three months after the optionee ceases to be such an employee,
          the option may be exercised by the person to whom it is transferred by
          will or the laws of descent and distribution within the period of one
          year after the date of death (or within such lesser period as may be
          specified in the applicable option agreement); and

          (iii) if the optionee becomes disabled (within the meaning of Section
          22(e)(3) of the Code or any successor provision thereto) while in the
          employ of the Company, the option may be exercised within the period
          of one year after the date the optionee ceases to be such an employee
          because of such disability (or within such lesser period as may be
          specified in the applicable option agreement);

provided, however, that in no event may any option be exercised after the
expiration date of the option. For all purposes of the Plan and any option
granted hereunder, "employment" shall be defined in accordance with the
provisions of Section 1.421-7(h) of the Income Tax Regulations (or any successor
regulations).

     (b)  Restricted Stock. The Board shall determine the effect on Restricted
Stock Awards of the disability, death, retirement, authorized leave of absence
or other change in the employment or other status of a Participant and the
extent to which, and the period during which,

                                  Page 5 of 27

<PAGE>

the Participant, or the Participant's legal representative, conservator,
guardian or Designated Beneficiary, may exercise rights under the Restricted
Stock Award or option agreement.

11.  Incentive Stock Options.

     Options granted under the Plan which are intended to be Incentive Stock
Options shall be specifically designated as Incentive Stock Options and shall be
subject to the following additional terms and conditions:

          (a)  Dollar Limitation. If Incentive Stock Options granted to any
          employee under the Plan (and any other incentive stock option plans of
          the Company), in the aggregate, become exercisable for the first time
          in any one calendar year for shares of Common Stock with an aggregate
          fair market value (determined as of the respective date or dates of
          grant) of more than $100,000, then, to the extent required under the
          Code, the option to acquire such excess shall be treated as a
          non-statutory option.

          (b)  10% Shareholder. If any employee to whom an Incentive Stock
          Option is to be granted under the Plan is, at the time of the grant of
          such option, the owner of stock possessing more than 10% of the total
          combined voting power of all classes of stock of the Company (after
          taking into account the attribution of stock ownership rules of
          Section 424(d) of the Code), then, to the extent required under the
          Code, the option shall be treated as a non-statutory option unless the
          following special provisions are applicable to the option granted to
          such individual:

               (i)  The purchase price per share of the Common Stock subject to
               such Incentive Stock Option shall not be less than 110% of the
               fair market value of one share of Common Stock at the time of
               grant; and

               (ii) The option exercise period shall not exceed five years from
               the date of grant.

12.  Additional Provisions.

     (a)  Additional Option Provisions. The Board of Directors may, in its sole
discretion, include additional provisions in any option granted under the Plan,
including, without limitation, restrictions on transfer, repurchase rights,
commitments to pay cash bonuses, make or arrange for loans or transfer other
property to optionees upon exercise of options, or such other provisions as
shall be determined by the Board of Directors; provided that such additional
provisions shall not be inconsistent with any other term or condition of the
Plan and such additional provisions shall not cause any Incentive Stock Option
granted under the Plan to fail to qualify as an Incentive Stock Option within
the meaning of Section 422 of the Code.

     (b)  Acceleration. The Board of Directors may, in its sole discretion,
accelerate the date or dates on which all or any particular option or options
granted under the Plan may be exercised.

                                  Page 6 of 27

<PAGE>

13.  General Restrictions.

     (a)  Investment Representations. The Company may require any person to whom
an option is granted, as a condition of exercising such option, to give written
assurances in substance and form satisfactory to the Company to the effect that
such person is acquiring the Common Stock subject to the option for his or her
own account for investment and not with any present intention of selling or
otherwise distributing the same, and to such other effects as the Company deems
necessary or appropriate in order to comply with federal and applicable state
securities laws.

     (b)  Compliance With Securities Laws. Each option shall be subject to the
requirement that if, at any time, counsel to the Company shall determine that
the listing, registration or qualification of the shares subject to such option
upon any securities exchange or under any state or federal law, or the consent
or approval of any governmental or regulatory body, is necessary as a condition
of, or in connection with, the issuance or purchase of shares thereunder, such
option may not be exercised, in whole or in part, unless such listing,
registration, qualification, consent or approval shall have been effected or
obtained on conditions acceptable to the Board of Directors. Nothing herein
shall be deemed to require the Company to apply for or to obtain such listing,
registration or qualification.

14.  Rights as a Shareholder.

     The holder of an option shall have no rights as a shareholder with respect
to any shares covered by such option until the date of issue of a stock
certificate to him or her for such shares. Except as provided below in Section
15, no adjustment shall be made for dividends or other rights for which the
record date is prior to the date such stock certificate is issued.

15.  Adjustments.

     (a)  General. If, as a result of a merger, consolidation, sale of all or
substantially all of the assets of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other distribution with respect to the outstanding shares of Common
Stock or other securities, the outstanding shares of Common Stock are increased
or decreased, or are exchanged for a different number or kind of shares or other
securities, or additional shares or new or different shares or other securities
are distributed with respect to such shares of Common Stock or other securities,
an appropriate and proportionate adjustment may be made in (i) the maximum
number and kind of shares reserved for issuance under the Plan, (ii) the number
and kind of shares or other securities subject to then outstanding options under
the Plan, and (iii) the price for each share subject to any then outstanding
options under the Plan, without changing the aggregate purchase price as to
which such options remain exercisable.

     (b)  Board Authority to Make Adjustments. Adjustments under this Section 15
will be made by the Board of Directors, whose determination as to what
adjustments, if any, will be made and the extent thereof will be final, binding
and conclusive. No fractional shares will be issued under the Plan on account of
any such adjustments.

16.  Reorganization.

     (a) General. In the event of a consolidation or merger in which the Company
is not the surviving corporation, or which results in the acquisition of
substantially all of the Company's outstanding Common Stock by a single person,
entity or group of persons or entities acting in concert, or in the event of the
sale or transfer of all or substantially all of the assets of the Company, or in
the event of a reorganization or liquidation of the Company (each, an "Organic
Event"), the Board of Directors of the Company, or the board of directors of any
corporation assuming the obligations of the Company, shall, as to outstanding
options, either (i) provide that such options shall be assumed, or equivalent
options shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof), provided that any such options substituted for Incentive
Stock Options shall meet the requirements of Section 424(a) of the Code, (ii)
upon written notice to the optionees, provide that all unexercised options will
terminate immediately prior to the consummation of such merger, consolidation,
acquisition, reorganization, liquidation, sale or transfer unless exercised by
the optionee within a specified number of days following the date of such
notice, or (iii) in the event of a merger under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the merger (the "Merger Price"), make or
provide for a cash payment to the optionees equal to the difference between (A)
the Merger Price times the number of shares of Common Stock subject to such
outstanding options (to the extent exercisable) and (B) the aggregate exercise
price of all such outstanding options in exchange for the termination of such
options. In any such case, the Board of Directors may, in its discretion,
advance the lapse of any waiting or installment periods and exercise dates.

     (b) Substitute Options. The Company may grant options under the Plan in
substitution for options held by employees of another corporation who become
employees of the Company, or a subsidiary of the Company, as the result of a
merger or consolidation of the employing corporation with the Company or a
subsidiary of the Company, or as a result of the acquisition by the Company, or
one of its subsidiaries, of property or stock of the employing corporation. The
Company may direct that substitute options be granted on such terms and
conditions as the Board of Directors considers appropriate in the circumstances.

     (c) Parachute Awards. If, in connection with an Organic Event, a tax under
Section 4999 of the Code would be imposed on an optionholder or a Participant
(after taking into account the exceptions set forth in Sections 280G(b)(4) and
280G(b)(5) of the Code), then the number of options or Restricted Stock Award
which shall become exercisable, realizable or vested as provided in such section
shall be reduced (or delayed), to the minimum extent necessary, so that no such
tax would be imposed on the optionholder or Participant (the options or
Restricted Stock Award not becoming so accelerated, realizable or vested, the
"Parachute Awards"; provided, however, that if the "Aggregate Present Value" of
the Parachute Awards would exceed the tax that, but for this sentence, would be
imposed on the optionholder or Participant under Section 4999 of the Code in
connection with the Organic Event, then the options or Restricted Stock Award
shall become immediately exercisable, realizable and vested without regard to
the provisions of this sentence. For purposes of the preceding sentence, the
"Aggregate Present Value" of an option or Restricted Stock Award shall be
calculated on an after-tax basis (other than taxes imposed by Section 4999 of
the Code) and shall be based on economic principles rather than the principles
set forth under Section 280G of the Code and the regulations

                                  Page 8 of 27

<PAGE>

promulgated thereunder. All determinations required to be made under this
Section 16(c) shall be made by the Company.

17.  No Special Employment Rights.

     Nothing contained in the Plan or in any option shall confer upon any
optionee any right with respect to the continuation of his or her employment by
the Company or interfere in any way with the right of the Company at any time to
terminate such employment or to increase or decrease the compensation of the
optionee. Whether an authorized leave of absence or absence due to military or
government service shall constitute termination of employment shall be
determined at the time of such absence in accordance with the provisions of
Section 1.421-7(h) of the Income Tax Regulations (or any successor regulations).

18.  Other Employee Benefits.

     The amount of any compensation deemed to be received by an employee as a
result of the exercise of an option or the sale of shares received upon such
exercise will not constitute compensation with respect to which any other
employee benefits of such employee are determined, including, without
limitation, benefits under any bonus, pension, profit-sharing, life insurance or
salary continuation plan, except as otherwise specifically determined by the
Board of Directors.

19.  Amendment of the Plan.

     The Board of Directors may at any time, and from time to time, modify or
amend the Plan in any respect, except that if at any time the approval of the
shareholders of the Company is required under Section 422 of the Code or any
successor provision with respect to Incentive Stock Options, or under Rule
16b-3, the Board of Directors may not effect such modification or amendment
without such approval. The termination or any modification or amendment of the
Plan shall not, without the consent of an optionee, affect his or her rights
under an option previously granted to him or her. With the consent of the
optionee or Participant affected, the Board of Directors may amend outstanding
option or stock restriction agreements in a manner not inconsistent with the
Plan. The Board of Directors shall have the right to amend or modify the terms
and provisions of the Plan and of any outstanding Incentive Stock Options
granted under the Plan to the extent necessary to qualify any or all such
options for such favorable federal income tax treatment (including deferral of
taxation upon exercise) as may be afforded incentive stock options under Section
422 of the Code.

20.  Withholding.

     (a)  The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of Options under the Plan. Subject to the prior approval of the Company, which
may be withheld by the Company in its sole discretion, the optionee may elect to
satisfy such obligations, in whole or in part, (i) by causing the Company to
withhold shares of Common Stock otherwise issuable pursuant to the exercise of
an Option, (ii) by delivering to the Company shares of Common Stock already
owned by the optionee, or (iii) by delivering cash. The shares so delivered or
withheld shall have a fair market value equal to such withholding obligation.
The fair market value of the shares used to satisfy such withholding obligation
shall be determined

                                  Page 9 of 27

<PAGE>

by the Company as of the date that the amount of tax to be withheld is to be
determined. An optionee who has made an election pursuant to this Section 20(a)
may only satisfy his or her withholding obligation with shares of Common Stock
which are not subject to any repurchase, forfeiture, unfulfilled vesting or
other similar requirements.

     (b)  83(b) Election. When applicable, the Company will make available to
each Participant a blank Form 83(b) for completion and filing by the Participant
in the applicable office of the Internal Revenue Service; provided, however,
that the Company shall be under no obligation to ensure that any such form is
properly completed or filed. Except as expressly required by applicable tax
laws, the Company shall have no liability with respect to any taxes due by
reason of the Restricted Stock Award.

     (c)  Notwithstanding the foregoing, in the case of an optionee subject to
the reporting requirements of Section 16(a) of the Exchange Act, no election to
use shares for the payment of withholding taxes shall be effective unless made
in compliance with any applicable requirements of Rule 16b-3(e) or any successor
rule under such Act.

21.  Cancellation and New Grant of Options.

     The Board of Directors shall have the authority to effect, at any time and
from time to time, with the consent of the affected optionees, the cancellation
of any or all outstanding options under the Plan and the grant in substitution
therefor of new options under the Plan covering the same or different numbers of
shares of Common Stock having an option exercise price per share which may be
lower or higher than the exercise price per share of the cancelled options.

22.  Effective Date and Duration of the Plan.

     (a)  Effective Date. The Plan shall become effective when adopted by the
Board of Directors, but no Incentive Stock Option granted under the Plan shall
become exercisable unless and until the Plan shall have been approved by the
Company's shareholders. If such shareholder approval is not obtained within
twelve months before or after the date of the Board's adoption of the Plan, any
Incentive Stock Options previously granted under the Plan shall terminate and no
further Incentive Stock Options shall be granted. Amendments to the Plan not
requiring shareholder approval shall become effective when adopted by the Board
of Directors; amendments requiring shareholder approval (as provided in Section
19) shall become effective when adopted by the Board of Directors, but no
Incentive Stock Option issued after the date of such amendment shall become
exercisable (to the extent that such amendment to the Plan was required to
enable the Company to grant such Incentive Stock Option to a particular
optionee) unless and until such amendment shall have been approved by the
Company's shareholders. If such shareholder approval is not obtained within
twelve months of the Board's adoption of such amendment, any Incentive Stock
Options granted on or after the date of such amendment shall terminate to the
extent that such amendment to the Plan was required to enable the Company to
grant such option to a particular optionee. Subject to this limitation, options
may be granted under the Plan at any time after the effective date and before
the date fixed for termination of the Plan.

     (b)  Termination. The Plan shall terminate upon the earlier of (i) the
close of business on the day next preceding the tenth anniversary of the date of
its adoption by the Board of Directors (or

                                  Page 10 of 27

<PAGE>

approval by shareholders, if earlier), or (ii) the date on which all shares
available for issuance under the Plan shall have been issued pursuant to the
exercise or cancellation of options granted under the Plan. If the date of
termination is determined under (i) above, then options outstanding on such date
shall continue to have force and effect in accordance with the provisions of the
instruments evidencing such options.

                            ON TECHNOLOGY CORPORATION

                        INCENTIVE STOCK OPTION AGREEMENT

     1. Grant of Option. ON Technology Corporation, a Delaware corporation (the
"Company"), hereby grants to __________ (the "Employee"), an option, pursuant to
the Company's 2002 Employee and Consultant Stock Option and Incentive Plan (the
"Plan"), to purchase an aggregate of ________ shares of Common Stock, $0.01 par
value ("Common Stock"), of the Company at a price of $ _______ per share,
purchasable as set forth in and subject to the terms and conditions of this
option and the Plan. Except where the context otherwise requires, the term
"Company" shall include the parent and all subsidiaries of the Company as
defined in Sections 424(e) and 424(f) of the Internal Revenue Code of 1986, as
amended (the "Code").

     2. Incentive Stock Option. This option is intended to qualify as an
incentive stock option ("Incentive Stock Option") within the meaning of Section
422 of the Code.

     3. Exercise of Option and Provisions for Termination.

        (a) Vesting Schedule. Except as otherwise provided in this Agreement,
this option may be exercised prior to the tenth anniversary of the date of grant
(or five years in the case of an option described in paragraph (b) of Section 11
of the Plan) (hereinafter the "Expiration Date") in installments as to not more
than the number of shares and during the respective installment periods set
forth in the table below. The right of exercise shall be cumulative so that if
the option is not exercised to the maximum extent permissible during any
exercise period it shall be exercisable, in whole or in part, with respect to
all shares not so purchased at any time prior to the Expiration Date or the
earlier termination of this option.

                                                          Total Number of
                       Exercise Period                   Shares Exercisable

This option may not be exercised at any time on or after the Expiration Date.

        (b) Exercise Procedure. Subject to the conditions set forth in this
Agreement, this option shall be exercised by the Employee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4. Such exercise shall
be effective upon receipt by the Treasurer of the Company of such written notice
together with the required payment. The Employee may purchase less than the
number of shares

                                 Page 12 of 27

<PAGE>

covered hereby, provided that no partial exercise of this option may be for any
fractional share or for fewer than ten whole shares.

          (c) Except as otherwise provided in this Section 3, this option may
not be exercised unless the Employee, at the time he or she exercises this
option, is, and has been at all times since the date of grant of this option, an
employee of the Company. For all purposes of this option, (i) "employment" shall
be defined in accordance with the provisions of Section 1.421-7(h) of the Income
Tax Regulations or any successor regulations, and (ii) if this option shall be
assumed or a new option substituted therefor in a transaction to which Section
424(a) of the Code applies, employment by such assuming or substituting
corporation (hereinafter called the "Successor Corporation") shall be considered
for all purposes of this option to be employment by the Company.

          (d) Exercise Period Upon Termination of Employment. If the Employee
ceases to be employed by the Company for any reason other than death or
disability or a discharge for "cause," as provided below, the right to exercise
this option shall terminate three months after such cessation (but in no event
after the Expiration Date), provided that this option shall be exercisable only
to the extent that the Employee was entitled to exercise this option on the date
of such cessation.

          (e) Exercise Period Upon Death or Disability. If the Employee dies or
becomes disabled (within the meaning of Section 22(e)(3) of the Code or any
successor provision thereto) prior to the Expiration Date while he or she is an
employee of the Company, or if the Employee dies within three months after the
Employee ceases to be an employee of the Company (other than as the result of a
discharge for "cause" as specified in paragraph (f) below), this option shall be
exercisable, within the period of one year following the date of death or
disability of the Employee (but in no event after the Expiration Date), by the
Employee or by the person to whom this option is transferred by will or the laws
of descent and distribution or pursuant to a qualified domestic relations order
(as defined in the Code) or Title I of the Employee Retirement Income Security
Act, or the rules thereunder, provided that this option shall be exercisable
only to the extent that this option was exercisable by the Employee on the date
of his or her death or disability. Except as otherwise indicated by the context,
the term "Employee," as used in this option, shall be deemed to include the
estate of the Employee or any person who acquires the right to exercise this
option by bequest or inheritance or otherwise by reason of the death of the
Employee or pursuant to a qualified domestic relations order (as defined in the
Code) or Title I of the Employee Retirement Income Security Act, or the rules
thereunder.

          (f) Discharge for Cause. If the Employee, prior to the Expiration
Date, ceases his or her employment with the Company because he or she is
discharged for "cause" (as defined below), the right to exercise this option
shall terminate immediately upon such cessation of employment. "Cause" shall
mean any of the following as determined by the Company, which determination
shall be conclusive: (i) breach of Employee's Employee Agreement or the terms of
Employee's employment offer letter in any material respect; (ii) gross failure
or habitual neglect to perform Employee's duties as an employee of the Company;
(iii) willful refusal or failure to comply with explicit, lawful directives of
the Company or its Board of Directors given in good faith; (iv) conviction of a
criminal felony; (v) fraud or embezzlement involving the assets of the Company
or

                                 Page 13 of 27

<PAGE>

other material misappropriation of the Company's assets or funds; or (vi)
willful misconduct or acts of bad faith with respect to the Company and its
policies in connection with and related to Employee's employment.

     4.  Payment of Purchase Price.

         (a) Method of Payment. Payment of the purchase price for shares
purchased upon exercise of this option shall be made by delivery to the Company
of cash or a check to the order of the Company in an amount equal to the
purchase price of such shares, or by delivery to the Company of shares of Common
Stock of the Company then owned by the Employee having a fair market value equal
in amount to the purchase price of such shares, or by any combination of such
methods of payment.

         (b) Valuation of Shares Tendered in Payment of Purchase Price. For the
purposes hereof, the fair market value of any share of the Company's Common
Stock which may be delivered to the Company in exercise of this option shall be
determined in good faith by the Board of Directors of the Company.

         (c) Delivery of Shares Tendered in Payment of Purchase Price. If the
Employee exercises options by delivery of shares of Common Stock of the Company,
the certificate or certificates representing the shares of Common Stock of the
Company to be delivered shall be duly executed in blank by the Employee or shall
be accompanied by a stock power duly executed in blank suitable for purposes of
transferring such shares to the Company. Fractional shares of Common Stock of
the Company will not be accepted in payment of the purchase price of shares
acquired upon exercise of this option.

         (d) Restrictions on Use of Option Stock. Notwithstanding the foregoing,
no shares of Common Stock of the Company may be tendered in payment of the
purchase price of shares purchased upon exercise of this option if the shares to
be so tendered were acquired within twelve (12) months before the date of such
tender, through the exercise of an option granted under the Plan or any other
stock option or restricted stock plan of the Company.

     5.  Delivery of Shares. The Company shall, upon payment of the option price
for the number of shares purchased and paid for, make prompt delivery of such
shares to the Employee, provided that if any law or regulation requires the
Company to take any action with respect to such shares before the issuance
thereof, then the date of delivery of such shares shall be extended for the
period necessary to complete such action.

     6.  Non-transferability of Option. Except as provided in paragraph (e) of
Section 3, this option is personal and no rights granted hereunder may be
transferred, assigned, pledged or hypothecated in any way (whether by operation
of law or otherwise) nor shall any such rights be subject to execution,
attachment or similar process. Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of this option or of such rights contrary to
the provisions hereof, or upon the levy of any attachment or similar process
upon this option or such rights, this option and such rights shall, at the
election of the Company, become null and void.

                                 Page 14 of 27

<PAGE>

     7.  No Special Employment Rights. Nothing contained in the Plan or this
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Employee for the period
within which this option may be exercised. However, during the period of the
Employee's employment, the Employee shall render diligently and faithfully the
services which are assigned to the Employee from time to time by the Board of
Directors or by the executive officers of the Company and shall at no time take
any action which, directly or indirectly, would be inconsistent with the best
interests of the Company.

     8.  Rights as a Shareholder. The Employee shall have no rights as a
shareholder with respect to any shares which may be purchased by exercise of
this option unless and until a certificate representing such shares is duly
issued and delivered to the Employee. No adjustment shall be made for dividends
or other rights for which the record date is prior to the date such stock
certificate is issued.

     9.  Adjustments.

         (a) General. If, as a result of a merger, consolidation, sale of all or
substantially all of the assets of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other distribution with respect to the outstanding shares of Common
Stock or other securities, the outstanding shares of Common Stock are increased
or decreased, or are exchanged for a different number or kind of shares or other
securities, or additional shares or new or different shares or other securities
are distributed with respect to such shares of Common Stock or other securities,
an appropriate and proportionate adjustment may be made in (i) the number and
kind of shares or other securities subject to this option and (ii) the price for
each share subject to this option, without changing the aggregate purchase price
as to which this option remains exercisable.

         (b) Board Authority to Make Adjustments. Adjustments under this Section
9 will be made by the Board of Directors, whose determination as to what
adjustments, if any, will be made and the extent thereof will be final, binding
and conclusive. No fractional shares will be issued pursuant to this option on
account of any such adjustments.

         (c) Limits on Adjustments. No adjustment shall be made under this
Section 9 which would, within the meaning of any applicable provision of the
Code, constitute a modification, extension or renewal of this option or a grant
of additional benefits to the Employee.

     10. Mergers, Etc.

         (a) General. In the event of a consolidation or merger in which the
Company is not the surviving corporation, or which results in the acquisition of
substantially all of the Company's outstanding Common Stock by a single person,
entity or group of persons or entities acting in concert, or in the event of the
sale or transfer of all or substantially all of the assets of the Company, or in
the event of a reorganization or liquidation of the Company, prior to the
Expiration Date or termination of this option (each, an "Organic Event"), the
Employee shall, with respect to

                                  Page 15 of 27

<PAGE>

this option or any unexercised portion hereof, be entitled to the rights and
benefits, and be subject to the limitations, set forth in Section 16 of the
Plan.

          (b)  Acceleration. In the event of the occurrence of an Organic Event
after three months following the date hereof, the vesting schedule set forth in
Section 3(a) of this Agreement shall be accelerated by 24 months, so that this
option shall be exercisable with respect to that number of shares which would
have been exercisable 24 months after the occurrence of such Organic Event, but
for the occurrence of the Organic Event.

     11.  Withholding Taxes. The Company's obligation to deliver shares upon the
exercise of this option shall be subject to the Employee's satisfaction of all
applicable federal, state and local income and employment tax withholding
requirements.

     12.  Limitations on Disposition of Incentive Stock Option Shares. It is
understood and intended that this option shall qualify as an "incentive stock
option" as defined in Section 422 of the Code. Accordingly, the Employee
understands that in order to obtain the benefits of an incentive stock option
under Section 421 of the Code, no sale or other disposition may be made of any
shares acquired upon exercise of the option within one year after the day of the
transfer of such shares to him, nor within two years after the grant of the
option. If the Employee intends to dispose, or does dispose (whether by sale,
exchange, gift, transfer or otherwise), of any such shares within said periods,
he or she will notify the Company in writing within ten days after such
disposition.

     13.  Miscellaneous.

          (a)  Except as provided herein, this option may not be amended or
otherwise modified unless evidenced in writing and signed by the Company and the
Employee.

          (b)  All notices under this option shall be mailed or delivered by
hand to the parties at their respective addresses set forth beneath their names
below or at such other address as may be designated in writing by either of the
parties to one another.

          (c)  This option shall be governed by and construed in accordance with
the laws of the State of Delaware.

term "Company" shall include the parent and all subsidiaries of the Company as
defined in Sections 424(e) and 424(f) of the Code.

     2.  Exercise of Option and Provisions for Termination.

         (a) Vesting Schedule. Except as otherwise provided in this Agreement,
this option may be exercised prior to the date 30 days after the tenth

cumulative so that if the option is not exercised to the maximum extent
permissible during any exercise period it shall be exercisable, in whole or in
part, with respect to all shares not so purchased at any time prior to the
Expiration Date or the earlier termination of this option.

                                                               Total Number of

         (d) Exercise Period Upon Death or Disability. If the Optionee dies or
becomes disabled (within the meaning of Section 22(e)(3) of the Code or any
successor provision thereto) prior to the Expiration Date, while he or she is an
employee of, advisory committee member of, or consultant to the Company, or if
the Optionee dies within three months after the Optionee ceases to be an
employee of, advisory committee member of, or consultant to the Company (other
than as the result of a discharge for "cause" or termination of a consulting
relationship for "cause", in each case as specified in paragraph (f) below),
this option shall be exercisable by the Optionee or by the person to whom this
option is transferred by will or the laws of descent and distribution or
pursuant to a qualified domestic relations order (as defined in the Code) or
Title I of the Employee Retirement Income Security Act, or the rules thereunder,
provided that this option shall be exercisable only to the extent that this
option was exercisable by the Optionee on the date of his or her death or
disability. Except as otherwise indicated by the context, the term "Optionee,"
as used in this option, shall be deemed to include the estate of the Optionee or
any person who acquires the right to exercise this option by bequest or
inheritance or otherwise by reason of the death of the Optionee or pursuant to a
qualified domestic relations order (as defined in the Code) or Title I of the
Employee Retirement Income Security Act, or the rules thereunder.

         (e) Discharge for Cause. If the Optionee, prior to the Expiration Date,
ceases his or her employment or consulting relationship with the Company because
he or she is discharged or terminated for "cause" (as defined below), the right
to exercise this option shall terminate immediately upon such cessation of
employment. "Cause" shall mean any of the following as determined by the
Company, which determination shall be conclusive: (i) breach of Employee's
Employee Agreement or the terms of Employee's employment offer letter in any
material respect; (ii) gross failure or habitual neglect to perform Employee's
duties as an employee of the Company; (iii) willful refusal or failure to comply
with explicit, lawful directives of the Company or its Board of Directors given
in good faith; (iv) conviction of a criminal felony; (v) fraud or embezzlement
involving the assets of the Company or other material misappropriation of the
Company's assets or funds; or (vi) willful misconduct or acts of bad faith with
respect to the Company and its policies in connection with and related to
Employee's employment.

     3.  Payment of Purchase Price.

         (a) Method of Payment. Payment of the purchase price for shares
purchased upon exercise of this option shall be made by delivery to the Company
of cash or a check to the order of the Company in an amount equal to the
purchase price of such shares, or by delivery to the Company of shares of Common
Stock of the Company then owned by the Optionee having a fair market value equal
in amount to the purchase price of such shares, or by any combination of such
methods of payment.

         (b) Valuation of Shares Tendered in Payment of Purchase Price. For the
purposes hereof, the fair market value of any share of the Company's Common
Stock which may be delivered to the Company in exercise of this option shall be
determined in good faith by the Board of Directors of the Company.

<PAGE>

         (c) Delivery of Shares Tendered in Payment of Purchase Price. If the
Company permits the Optionee to exercise options by delivery of shares of Common
Stock of the Company, the certificate or certificates representing the shares of
Common Stock of the Company to be delivered shall be duly executed in blank by
the Optionee or shall be accompanied by a stock power duly executed in blank
suitable for purposes of transferring such shares to the Company. Fractional
shares of Common Stock of the Company will not be accepted in payment of the
purchase price of shares acquired upon exercise of this option.

         (d) Restrictions Upon Use of Option Stock. Notwithstanding the
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within twelve (12) months before the date
of such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     4.  Delivery of Shares. The Company shall, upon payment of the option price
for the number of shares purchased and paid for, make prompt delivery of such
shares to the Optionee, provided that if any law or regulation requires the
Company to take any action with respect to such shares before the issuance
thereof, then the date of delivery of such shares shall be extended for the
period necessary to complete such action.

     5.  Non-transferability of Option. Except as provided in paragraph (e) of
Section 2, this option is personal and no rights granted hereunder may be
transferred, assigned, pledged or hypothecated in any way (whether by operation
of law or otherwise) nor shall any such rights be subject to execution,
attachment or similar process. Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of this option or of such rights contrary to
the provisions hereof, or upon the levy of any attachment or similar process
upon this option or such rights, this option and such rights shall, at the
election of the Company, become null and void.

     6.  No Special Employment or Consulting Rights. Nothing contained in the
Plan or this option shall be construed or deemed by any person under any
circumstances to bind the Company to continue the employment of the Optionee or
the continuation of the consulting relationship with the Optionee for the period
within which this option may be exercised. However, during the period of the
Optionee's employment or consulting relationship, the Optionee shall render
diligently and faithfully the services which are assigned from time to time by
the Board of Directors or by the executive officers of the Company and shall at
no time take any action which directly or indirectly would be inconsistent with
the best interests of the Company.

     7.  Rights as a Shareholder. The Optionee shall have no rights as a
shareholder with respect to any shares which may be purchased by exercise of
this option unless and until a certificate representing such shares is duly
issued and delivered to the Optionee. No adjustment shall be made for dividends
or other rights for which the record date is prior to the date such stock
certificate is issued.

     8.  Recapitalization.

         (a) General. If, as a result of a merger, consolidation, sale of all or
substantially

                                  Page 20 of 27

<PAGE>

all of the assets of the Company, reorganization, recapitalization,
reclassification, stock dividend, stock split, reverse stock split or other
distribution with respect to the outstanding shares of Common Stock or other
securities, the outstanding shares of Common Stock are increased or decreased,
or are exchanged for a different number or kind of shares or other securities,
or if additional shares or new or different shares or other securities are
distributed with respect to such shares of Common Stock or other securities, an
appropriate and proportionate adjustment may be made in (i) the number and kind
of shares or other securities subject to this option and (ii) the price for each
share subject to this option, without changing the aggregate purchase price as
to which this option remains exercisable.

              (b)    Board Authority to Make Adjustments. Adjustments under this
Section 8 will be made by the Board of Directors, whose determination as to what
adjustments, if any, will be made and the extent thereof will be final, binding
and conclusive. No fractional shares will be issued under this option on account
of any such adjustments.

       9.     Mergers, Etc.

              (a)    General. In the event of a consolidation or merger in which
the Company is not the surviving corporation, or which results in the
acquisition of substantially all of the Company's outstanding Common Stock by a
single person, entity or group of persons or entities acting in concert, or in
the event of the sale or transfer of all or substantially all of the assets of
the Company, or in the event of a reorganization or liquidation of the Company,
prior to the Expiration Date or termination of this option (each, an "Organic
Event"), the Optionee shall, with respect to this option or any unexercised
portion hereof, be entitled to the rights and benefits, and be subject to the
limitations, set forth in Section 16 of the Plan.

              (b)    Acceleration. In the event of the occurrence of an Organic
Event, after three months following the date hereof, the vesting schedule set
forth in Section 3(a) of this Agreement shall be accelerated by 24 months so
that this option shall be exercisable with respect to that number of shares
which would have been exercisable 24 months after the occurrence of such Organic
Event but for the occurrence of the Organic Event.

       10.    Withholding Taxes. The Company's obligation to deliver shares upon
the exercise of this option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.

       11.    Miscellaneous.

              (a)    Except as provided herein, this option may not be amended
or otherwise modified unless evidenced in writing and signed by the Company and
the Optionee.

              (b)    All notices under this option shall be mailed or delivered
by hand to the parties at their respective addresses set forth beneath their
names below or at such other address as may be designated in writing by either

                            ON TECHNOLOGY CORPORATION

                           Stock Restriction Agreement

       THIS STOCK RESTRICTION AGREEMENT made as of the ___ day of ____, 200_
between ON Technology Corporation, a Delaware corporation (the "Company"), and
_________ (the "Stockholder").

       For valuable consideration, receipt of which is acknowledged, the Company
and the Stockholder agree as follows:

       1.     Stock. The Stockholder has previously acquired ________ shares of
the common stock, par value $.01 per share, of the Company (the "Shares").

       The Stockholder agrees that the Shares will be subject to a right of
repurchase by the Company as set forth in Section 2 of this Agreement (the
"Repurchase Right") and the restrictions on transfer set forth in Section 3 of
this Agreement.

       2.     Repurchase of Shares. (a)If the Stockholder's employment with the
Company is terminated, either by the Company or the Stockholder, for any reason
or for no reason (the date of such termination being hereinafter referred to as
the "Termination Date"), then the Company shall have the right to repurchase at
the Buyout Price (as defined below) the number of Shares set forth below;
provided, however, that in the event that the Stockholder is terminated for
Cause (as defined in the option agreement pursuant to which the Shares were
originally purchased), the Company shall have the right to repurchase all of the
Shares at the Exercise Price.

              (i)    If the Termination Date occurs on or before __________, the
Stockholder shall be entitled to retain _____ Shares and shall sell to the
Company ______ Shares;

              (ii)   If the Termination Date occurs after _____ but on or before
_____, the Stockholder shall be entitled to retain _____ Shares and shall sell
to the Company _____ Shares; and

              (iii)  If the Termination occurs after ________, the Stockholder

Price'), such consideration to be paid by the Company in cash or by check.

<PAGE>

              (b)    Notwithstanding anything herein to the contrary, in the
event of a consolidation or merger in which the Company is not the surviving
corporation, or which results in the acquisition of substantially all of the
Company's outstanding Common Stock by a single person, entity or group of
persons or entities acting in concert, or in the event of the sale or transfer
of all or substantially all of the assets of the Company, or in the event of a
reorganization or liquidation of the Company prior to the Termination Date
(each, an "Organic Event"), then, in connection with the consummation of such
Organic Event, the dates set forth in the vesting provisions of clause (a) shall
be accelerated by 24 months and the number of Shares otherwise subject to
repurchase by the Company pursuant to this Section 2 shall be automatically
adjusted to reflect the acceleration of such dates.

       3.     Restrictions on Transfer. The Stockholder shall not sell, assign,
transfer, pledge, hypothecate or otherwise dispose of, by operation of law or
otherwise (collectively "transfer"), any of the Shares or any other equity
interests of the Company, or any interest therein, unless and until such Shares
and other equity interests are no longer subject to repurchase by the Company
hereunder; provided, however, that the Stockholder may make transfers of the
Shares to or for the benefit of any spouse, child or grandchild, or to a trust
for their benefit (except no such transfers shall be made pursuant to any
divorce or separation proceedings unless the Board of Directors shall have
approved such transfer and the Stockholder retains voting control over such
Shares); provided, further, that such Shares shall remain subject to this
Agreement and such transferee shall, as a condition to transfer, agree in
writing to be bound by the terms of this Agreement.

       4.     Effect of Prohibited Transfer. The Company will not be required
(a) to transfer on its books any of the Shares or other equity interests which
has been sold or transferred in violation of any of the provisions set forth in
this Agreement, or (b) to treat as owner of such Shares or other equity
interests, or to pay dividends to, any transferee to whom any such Shares or
other equity interests has been so sold or transferred. In addition, in the
event that any Shares or other equity interests are sold or transferred
(including by operation of law or otherwise) in violation of any of the
provisions set forth in this Agreement, the Company will have the right and
option to purchase from the transferring Stockholder and any purported
transferee all of such Shares or other equity interests for a purchase price per
share equal to the Buyout Price. Any such purchase by the Company will be
effected in accordance with the procedures set forth in Section 2 of this
Agreement (and references to the Repurchase Right in such Section 2 shall be
deemed to refer to the option described in this Section 4 and references to
termination of employment in Section 2 shall be deemed to refer to a prohibited
transfer as described in this Section 4).

       5.     Restrictive Legend. All certificates representing Shares or other
equity interests subject to this Agreement will bear a legend in substantially
the following form, in addition to any other legends that may be required under
federal or state securities laws:

              "The Shares represented by this certificate are
              subject to restrictions on transfer and an option to
              purchase set forth in a certain Stock Restriction
              Agreement between the Company and the registered
              owner of this certificate (or his predecessor in
              interest), and such Agreement is available for
              inspection without charge at the office of the
              Treasurer of the Company."

     6.  Adjustments for Splits, Dividends, etc. If from time to time during the
term of the Repurchase Right there is any split-up, dividend, distribution or
other reclassification of the Shares, any and all new, substituted or additional
securities to which the Stockholder is entitled by reason of his ownership of
the Shares or other Company securities will be immediately subject to the
Repurchase Right, the restrictions on transfer and the other provisions of this
Agreement in the same manner and to the same extent as the Shares, and the
Buyout Price shall be appropriately adjusted.

     7.  Withholding Taxes.

         (a) The Stockholder acknowledges and agrees that the Company has the
right to deduct from payments of any kind otherwise due to the Stockholder any
federal, state or local taxes of any kind required by law to be withheld with
respect to the purchase of the Shares by the Stockholder.

         (b) If the Stockholder elects, in accordance with Section 83(b) of the
Internal Revenue Code of 1986, as amended, to recognize ordinary income in the
year of acquisition of the Shares, the Company will require at the time of such
election an additional payment for withholding tax purposes based on the
difference, if any, between the purchase price for such Shares and the fair
market value of such Shares as of the day immediately preceding the date of the
purchase of such Shares by the Stockholder.

     8.  Severability. The invalidity or unenforceability of an provision of
this Agreement will not affect the validity or enforceability of any other
provision of this Agreement, and each other provision of this Agreement will be
severable and enforceable to the extent permitted by law.

     9.  Waiver. Any provision contained in this Agreement may be waived, either
generally or in any particular instance, by the Board of Directors of the
Company.

benefit of the Company and the Stockholder and their respective heirs,
executors, administrators, legal representatives, successors and assigns,
subject to the restrictions on transfer set forth in Section 3 of this
Agreement.

     11. No Rights To Employment. Nothing contained in this Agreement is to be
construed as giving the Stockholder any right to be retained, in any position,
as an employee of or consultant to the Company.

     12. Notice. All notices required or permitted hereunder must be in writing
and are deemed effectively given upon personal delivery or upon deposit in the
