                        WORKGROUP TECHNOLOGY CORPORATION

                                 1992 STOCK PLAN
                                 ---------------

     1.   Purpose. This 1992 Stock Plan (the "Plan") is intended to provide
          -------
incentives: (a) to the officers and other employees of WorkGroup Technology
Corporation (the "Company"), its parent (if any) and any present or future
subsidiaries of the Company (collectively, "Related Corporations") by providing
them with opportunities to purchase stock in the Company pursuant to options
granted hereunder which qualify as "incentive stock options" under Section
422(b) of the Internal Revenue Code of 1986, as amended (the "Code") ("ISO" or
"ISOs"); (b) to directors, officers, employees and consultants of the Company
and Related Corporations by providing them with opportunities to purchase stock
in the Company pursuant to options granted hereunder which do not qualify as
ISOs ("Non-Qualified Option" or "Non-Qualified Options"); (c) to directors,
officers, employees and consultants of the Company and Related Corporations by
providing them with awards of stock in the Company ("Awards"); and (d) to
directors, officers, employees and consultants of the Company and Related
Corporations by providing them with opportunities to make direct purchases of
stock in the Company ("Purchases"). Both ISOs and Non-Qualified Options are
referred to hereafter individually as an "Option" and collectively as "Options".
Options, Awards and authorizations to make Purchases are referred to hereafter
collectively as "Stock Rights". As used herein, the terms "parent" arid
"subsidiary" mean "parent corporation" and "subsidiary corporation",
respectively, as those terms are defined in Section 424 of the Code.

     2.   Administration of the Plan.
          --------------------------

          A. Board or Committee Administration. The Plan shall be administered
             ---------------------------------
by the Board of Directors of the Company (the "Board") or by a committee
appointed by the Board (the "Committee"); provided, that, to the extent required
by Rule 16b-3, or any successor provision ("Rule 16b-3"), of the Securities
Exchange Act of 1934, with respect to specific grants of Stock Rights, the Plan
shall be administered by a disinterested administrator or administrators within
the meaning of Rule 16b-3. Hereinafter, all references in this Plan to the
"Committee" shall mean the Board if no Committee has been appointed. Subject to
ratification of the grant or authorization of each Stock Right by the Board (if
so required by applicable state law), and subject to the terms of the Plan, the
Committee shall have the authority to (i) determine the employees of the Company
and Related Corporations (from among the class of employees eligible under
paragraph 3 to receive ISOs) to whom ISOs may be granted, and to determine (from
among the class of individuals and entities eligible under paragraph 3 to
receive Non-Qualified Options and Awards and to make Purchases) to whom
Non-Qualified Options, Awards and authorizations to make Purchases may be
granted; (ii) determine the time or times at which Options or Awards may be
granted or Purchases made; (iii) determine the option price of shares subject to
each Option, which price shall not be less than the minimum price specified in
paragraph 6, and the purchase price of shares subject to each Purchase; (iv)
determine whether each Option granted shall be an ISO or a Non-Qualified Option;
(v) determine (subject to paragraph 7) the time or times when each option shall
become exercisable and the duration of the

<PAGE>

                                      -2-

exercise period; (vi) determine whether restrictions such as repurchase options
are to be imposed on shares subject to Options, Awards and Purchases and the
nature of such restrictions, if any, and (vii) interpret the Plan and prescribe
and rescind rules and regulations relating to it. If the Committee determines to
issue a Non-Qualified Option, it shall take whatever actions it deems necessary,
under Section 422 of the Code and the regulations promulgated thereunder, to
ensure that such Option is not treated as an ISO. The interpretation and
construction by the Committee of any provisions of the Plan or of any Stock
Right granted under it shall be final unless otherwise determined by the Board.
The Committee may from time to time adopt such rules and regulations for
carrying out the Plan as it may deem best. No member of the Board or the
Committee shall be liable for any action or determination made in good faith
with respect to the Plan or any Stock Right granted under it.

          B. Committee Actions. The Committee may select one of its members as
             -----------------
its chairman, and shall hold meetings at such times and places as it may
determine. Acts by a majority of the Committee, or acts reduced to or approved
in writing by a majority of the members of the Committee (if consistent with
applicable state law), shall be the valid acts of the Committee. From time to
time the Board may increase the size of the Committee and appoint additional
members thereof, remove members (with or without cause) and appoint new members
in substitution therefor, fill vacancies however caused, or remove all members
of the Committee and thereafter directly administer the Plan.

          C. Grant of Stock Rights to Board Members. Stock Rights may be granted
             --------------------------------------
to members of the Board consistent with the provisions of the first sentence of
paragraph 2(A) above, if applicable. All grants of Stock Rights to members of
the Board shall in all other respects be made in accordance with the provisions
of this Plan applicable to other eligible persons. Consistent with the
provisions of the first sentence of paragraph 2(A) above, members of the Board
who are either (i) eligible for Stock Rights pursuant to the Plan or (ii) have
been granted Stock Rights may vote on any matters affecting the administration
of the Plan or the grant of any Stock Rights pursuant to the Plan, except that
no such member shall act upon the granting to himself of Stock Rights, but any
such member may be counted in determining the existence of a quorum at any
meeting of the Board during which action is taken with respect to the granting
to him of Stock Rights.

     3.   Eligible Employees and Others. ISOs may be granted to any employee of
          -----------------------------
the Company or any Related Corporation. Those officers and directors of the
Company who are not employees may not be granted ISOs under the Plan.
Non-Qualified Options, Awards and authorizations to make Purchases may be
granted to any employee, officer or director (whether or not also an employee)
or consultant of the Company or any Related Corporation. The Committee may take
into consideration a recipient's individual circumstances in determining whether
to grant an ISO, a Non-Qualified Option, an Award or an authorization to make a
Purchase. Granting of any Stock Right to any individual or entity shall neither
entitle that individual or entity to, nor disqualify him from, participation in
any other grant of Stock Rights.

     4.   Stock. The stock subject to Options, Awards and Purchases shall be
          -----
authorized but unissued shares of Common Stock of the Company, par value $.01
per share (the "Common Stock"), or shares of Common Stock reacquired by the
Company in any manner. The aggregate number of shares which may be issued
pursuant to the Plan is 1,787,500, subject to adjustment as

<PAGE>

                                      -3-

provided in paragraph 13. Any such shares may be issued pursuant to any type of
Stock Rights granted under the Plan, so long as the number of shares so issued
does not exceed such number, as adjusted. If any Stock Right granted under the
Plan shall expire or terminate for any reason without having been exercised in
full or shall cease for any reason to be exercisable in whole or in part, the
unpurchased shares subject to such Stock Right shall again be available for
grants of Stock Rights under the Plan. For the purposes of the foregoing
sentence, shares withheld from the Stock Right exercise to pay the exercise
price and/or tax consequences of the exercise shall be deemed to have been
issued.

     5.   Granting of Stock Rights. Stock Rights may be granted under the Plan
          ------------------------
at any time after May 12, 1992 and prior to May 11, 2002. The date of grant of a
Stock Right under the Plan will be the date specified by the Committee at the
time it grants the Stock Right; provided, however, that such date shall not be
prior to the date on which the Committee acts to approve the grant. The
Committee shall have the right, with the consent of the Optionee, to convert an
ISO granted under the Plan to a Non-Qualified Option pursuant to paragraph 16.

     6.   Minimum Option Price; ISO Limitations.
          -------------------------------------

          A. Price for Non-Qualified Options. The exercise price per share
             -------------------------------
specified in the agreement relating to each Non-Qualified Option granted under
the Plan shall in no event be less than the minimum legal consideration required
therefor under the laws of Delaware or the laws of any jurisdiction in which the
Company or its successors in interest may be organized.

          B. Price for ISOs. The exercise price per share specified in the
             --------------
agreement relating to each ISO granted under the Plan shall not be less than the
fair market value per share of Common Stock on the date of such grant. In the
case of an ISO to be granted to an employee owning stock possessing more than
ten percent (10%) of the total combined voting power of all classes of stock of
the Company or any Related Corporation, the price per share specified in the
agreement relating to such ISO shall not be less than one hundred ten percent
(110%) of the fair market value per share of Common Stock on the date of grant.
For purposes of determining stock ownership under this paragraph, the rules of
Section 424(d) of the Code shall apply.

          C. $100,000 Annual Limitation on ISO Vesting. Each eligible employee
             -----------------------------------------
may be granted Options treated as ISOs only to the extent that, in the aggregate
under this Plan and all incentive stock option plans of the Company and any
Related Corporation, ISOs do not become exercisable for the first time by such
employee during any calendar year with respect to stock having a fair market
value (determined at the time the ISOs were granted) in excess of $100,000. The
Company intends to designate any Options granted in excess of such limitation as
Non-Qualified Options, but if ISOs are granted in excess of such limitation the
Company will take such action as is requested by an optionee to designate shares
issued upon exercise of any Option required to be treated as in part an ISO and
in part a Non-Qualified option as having been issued pursuant to either an ISO
or a Non-Qualified Option, in accordance with applicable rules and regulations.

          D. Determination of Fair Market Value. If, at the time an Option is
             ----------------------------------
granted under the Plan, the Company's Common Stock is publicly traded, "fair
market value" shall be determined as of the last business day for which the
prices or quotes discussed in this sentence

<PAGE>

                                      -4-

are available prior to the date such Option is granted and shall mean (i) the
average (on that date) of the high and low prices of the Common Stock on the
principal national securities exchange on which the Common Stock is traded, if
the Common Stock is then traded on a national securities exchange; or (ii) the
last reported sale price (on that date) of the Common Stock on the NASDAQ
National Market List, if the Common Stock is not then traded on a national
securities exchange; or (iii) the closing bid price (or average of bid prices)
last quoted (on that date) by an established quotation service for
over-the-counter securities, if the Common Stock is not reported on the NASDAQ
National Market List. However, if the Common Stock is not publicly traded at the
time an Option is granted under the Plan, "fair market value" shall be deemed to
be the fair value of the Common Stock as determined by the Committee after
taking into consideration all factors which it deems appropriate, including,
without limitation, recent sale and offer prices of the Common Stock in private
transactions negotiated at arm's length.

     7.   Option Duration. Subject to earlier termination as provided in
          ---------------
paragraphs 9 and 10, each Option shall expire on the date specified by the
Committee, but not more than (i) ten years and one day from the date of grant in
the case of Non-Qualified Options, (ii) ten years from the date of grant in the
case of ISOs generally, and (iii) five years from the date of grant in the case
of ISOs granted to an employee owning stock possessing more than ten percent
(l00) of the total combined voting power of all classes of stock of the Company
or any Related Corporation, as determined under paragraph 6(B). Subject to
earlier termination as provided in paragraphs 9 and 10, the term of each ISO
shall be the term set forth in the original instrument granting such ISO, except
with respect to any part of such ISO that is converted into a Non-Qualified
Option pursuant to paragraph 16.

     8.   Exercise of Option. Subject to the provisions of paragraphs 9 through
          ------------------
12, each Option granted under the Plan shall be exercisable as follows:

          A. Vesting. The Option shall either be fully exercisable on the date
             -------
of grant or shall become exercisable thereafter in such installments as the
Committee may specify.

          B. Full Vesting of Installments. Once an installment becomes
             ----------------------------
exercisable it shall remain exercisable until expiration or termination of the
Option, unless otherwise specified by the Committee.

          C. Partial Exercise. Each Option or installment may be exercised at
             ----------------
any time or from time to time, in whole or in part, for up to the total number
of shares with respect to which it is then exercisable.

          D. Acceleration of Vesting. The Committee shall have the right to
             -----------------------
accelerate the date of exercise of any installment of any Option; provided that
the Committee shall not, without the consent of an optionee, accelerate the
exercise date of any installment of any Option granted to any employee as an ISO
(and not previously converted into a Non-Qualified Option pursuant to paragraph
16) if such acceleration would violate the annual vesting limitation contained
in Section 422(d) of the Code, as described in paragraph 6(C).

     9.   Termination of Employment. If an ISO optionee ceases to be employed by
          -------------------------
the Company and all Related Corporations other than by reason of death or
disability as defined in

<PAGE>

                                      -5-

paragraph 10, no further installments of his ISOs shall become exercisable, and
his ISOs shall terminate after the passage of ninety (90) days from the date of
termination of his employment, but in no event later than on their specified
expiration dates, except to the extent that such ISOs (or unexercised
installments thereof) have been converted into Non-Qualified Options pursuant to
paragraph 16. For purposes of this paragraph 9 only, employment shall be
considered as continuing uninterrupted during any bona fide leave of absence
(such as those attributable to illness, military obligations or governmental
service) provided that the period of such leave does not exceed 90 days or, if
longer, any period during which such optionee's right to reemployment is
guaranteed by statute. A bona fide leave of absence with the written approval of
the Committee shall not be considered an interruption of employment under this
paragraph 9, provided that such written approval contractually obligates the
Company or any Related Corporation to continue the employment of the optionee
after the approved period of absence. ISOs granted under the Plan shall not be
affected by any change of employment within or among the Company and Related
Corporations, so long as the optionee continues to be an employee of the Company
or any Related Corporation. Nothing in the Plan shall be deemed to give any
grantee of any Stock Right the right to be retained in employment or other
service by the Company or any Related Corporation for any period of time.

     10.  Death; Disability.
          -----------------

          A. Death. If an ISO optionee ceases to be employed by the Company and
             -----
all Related Corporations by reason of his death, any ISO of his may be
exercised, to the extent of the number of shares with respect to which he could
have exercised it on the date of his death, by his estate, personal
representative or beneficiary who has acquired the ISO by will or by the laws of
descent and distribution, at any time prior to the earlier of the specified
expiration date of the ISO or 180 days from the date of the optionee's death.

          B. Disability. If an ISO optionee ceases to be employed by the Company
             ----------
and all Related Corporations by reason of his disability, he shall have the
right to exercise any ISO held by him on the date of termination of employment,
to the extent of the number of shares with respect to which he could have
exercised it on that date, at any time prior to the earlier of the specified
expiration date of the ISO or 180 days from the date of the termination of the
optionee's employment. For the purposes of the Plan, the term "disability" shall
mean "permanent and total disability" as defined in Section 22(e)(3) of the Code
or successor statute.

     11.  Assignability. No Stock Right shall be assignable or transferable by
          -------------
the grantee except by will or by the laws of descent and distribution. During
the lifetime of the grantee each Stock Right shall be exercisable only by him.

     12.  Terms and Conditions of Options. Options shall be evidenced by
          -------------------------------
instruments (which need not be identical) in such forms as the Committee may
from time to time approve. Such instruments shall conform to the terms and
conditions set forth in paragraphs 6 through 11 hereof and may contain such
other provisions as the Committee deems advisable which are not inconsistent
with the Plan, including restrictions applicable to shares of Common Stock
issuable upon exercise of Options. In granting any Non-Qualified Option, the
Committee may specify that such Non-Qualified Option shall be subject to the
restrictions set forth herein with respect to ISOs, or to such other termination
and cancellation provisions as the Committee may determine.

<PAGE>

                                      -6-

The Committee may from time to time confer authority and responsibility on one
or more of its own members and/or one or more officers of the Company to execute
and deliver such instruments. The proper officers of the Company are authorized
and directed to take any and all action necessary or advisable from time to time
to carry out the terms of such instruments.

     13.  Adjustments. Upon the occurrence of any of the following events, an
          -----------
optionee's rights with respect to Options granted to him hereunder shall be
adjusted as hereinafter provided, unless otherwise specifically provided in the
written agreement between the optionee 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 Options 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.

          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 Committee 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 the
consideration payable with respect to the outstanding shares of Common Stock in
connection with the Acquisition; or (ii) upon written notice to the optionees,
provide that all Options must be exercised, to the extent then exercisable,
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 (to the extent then exercisable) 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, an optionee upon exercising an option shall be entitled to receive
for the purchase price paid upon such exercise the securities he would have
received if he had exercised his Option prior to such recapitalization or
reorganization.

          D. Modification of ISOs. Notwithstanding the foregoing, any
             --------------------
adjustments made pursuant to subparagraphs A, B or C with respect to ISOs shall
be made only after the Committee, 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 of the Code) or would cause any
adverse tax consequences for the holders of such ISOs. If the Committee
determines that such adjustments made with respect to ISOs would constitute a
modification of such ISOs, it may refrain from making such adjustments.

          E. Dissolution or Liquidation. In the event of the proposed
             --------------------------
dissolution or liquidation of the Company, each option will terminate
immediately prior to the consummation

<PAGE>

                                      -7-

of such proposed action or at such other time and subject to such other
conditions as shall be determined by the Committee.

          F. 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. No adjustments shall be made for dividends paid in cash or
in property other than securities of the Company.

          G. Fractional Shares. No fractional shares shall be issued under the
             -----------------
Plan and the optionee shall receive from the Company cash in lieu of such
fractional shares.

          H. Adjustments. Upon the happening of any of the events described in
             -----------
subparagraphs A, B or C above, the class and aggregate number of shares set
forth in paragraph 4 hereof that are subject to Stock Rights which previously
have been or subsequently may be granted under the Plan shall also be
appropriately adjusted to reflect the events described in such subparagraphs.
The Committee or the Successor Board shall determine the specific adjustments to
be made under this paragraph 13 and, subject to paragraph 2, its determination
shall be conclusive.

     If any person or entity owning restricted Common Stock obtained by exercise
of a Stock Right made hereunder receives shares or securities or cash in
connection with a corporate transaction described in subparagraphs A, B or C
above as a result of owning such restricted Common Stock, such shares or
securities or cash shall be subject to all of the conditions and restrictions
applicable to the restricted Common Stock with respect to which such shares or
securities or cash were issued, unless otherwise determined by the Committee or
the Successor Board.

     14.  Means of Exercising Stock Rights. A Stock Right (or any Part or
          --------------------------------
installment thereof) shall be exercised by giving written notice to the Company
at its principal office address. Such notice shall identify the Stock Right
being exercised and specify the number of shares as to which such Stock Right is
being exercised, accompanied by full payment of the purchase price therefor
either (a) in United States dollars in cash or by check, or (b) at the
discretion of the Committee, 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 Stock Right, (c) at the discretion of the Committee, by delivery of
the grantee's personal recourse note bearing interest payable not less than
annually at no less than 100% of the lowest applicable Federal rate, as defined
in Section 1274(d) of the Code, (d) at the discretion of the Committee and
consistent with applicable law, through the delivery of an assignment to the
Company of a sufficient amount of the proceeds from the sale of the Common Stock
acquired upon exercise of the Stock Right and an authorization to the broker or
selling agent to pay that amount to the Company, which sale shall be at the
participant's direction at the time of exercise, or (e) at the discretion of the
Committee, by any combination of (a), (b), (c) and (d) above. If the Committee
exercises its discretion to permit payment of the exercise price of an ISO by
means of the methods set forth in clauses (b), (c), (d) or (e) of the preceding
sentence, such discretion shall be exercised in writing at the time of the grant
of the ISO in question. The holder of a Stock Right shall not have the rights of
a shareholder with respect to the shares covered by his Stock Right until the
date of

<PAGE>

                                      -8-

issuance of a stock certificate to him for such shares. Except as expressly
provided above in paragraph 13 with respect to changes in capitalization and
stock dividends, no adjustment shall be made for dividends or similar rights for
which the record date is before the date such stock certificate is issued.

     15. Term and Amendment of Plan. This Plan was adopted by the Board of
         --------------------------
Directors of the Company on May 12, 1992, subject to approval by the
Stockholders on or before May 11, 1993. The Plan shall expire at the end of the
day on May 11, 2002 (except as to Options outstanding on that date). The Board
may terminate or amend the Plan in any respect at any time, except that, without
the approval of the stockholders obtained within 12 months before or after the
Board adopts a resolution authorizing any of the following actions: (a) the
total number of shares that may be issued under the Plan may not be increased
(except by adjustment pursuant to paragraph 13); (b) the benefits accruing to
participants under the Plan may not be materially increased; (c) the
requirements as to eligibility for participation in the Plan may not be
materially modified; (d) the provisions of paragraph 3 regarding eligibility for
grants of ISOs may not be modified; (e) the provisions of paragraph 6(B)
regarding the exercise price at which shares may be offered pursuant to ISOs may
not be modified (except by adjustment pursuant to paragraph 13); (f) the
expiration date of the Plan may not be extended; and (g) the Board may not take
any action which would cause the Plan to fail to comply with Rule 16b-3. Except
as otherwise provided in this paragraph 15, in no event may action of the Board
or stockholders alter or impair the rights of a grantee, without his consent,
under any Stock Right previously granted to him.

     16. Conversion of ISOs into Non-Qualified Options; Termination of ISOs. The
         ------------------------------------------------------------------
Committee, at the written request of any optionee, may in its discretion take
such actions as may be necessary to convert such optionee's ISOs (or any
installments or portions of installments 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 optionee is an employee of
the Company or a Related Corporation at the time of such conversion. Such
actions may include, but shall not be limited to, extending the exercise period
or reducing the exercise price of the appropriate installments of such ISOs. At
the time of such conversion, the Committee (with the consent of the optionee)
may impose such conditions on the exercise of the resulting Non-Qualified
Options as the Committee 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 optionee the right to have such optionee's ISOs converted
into Non-Qualified options, and no such conversion shall occur until and unless
the Committee takes appropriate action. The Committee, with the consent of the
optionee, may also terminate any portion of any ISO that has not been exercised
at the time of such termination.

     17. Application Of Funds. The proceeds received by the Company from the
         --------------------
sale of shares pursuant to options granted and Purchases authorized under the
Plan shall be used for general corporate purposes.

     18. Notice to Company of Disqualifying Disposition. By accepting an ISO
         ----------------------------------------------
granted under the Plan, each optionee agrees to notify the Company in writing
immediately after he or she makes a Disqualifying Disposition (as described in
Sections 421, 422 and 424 of the Code and regulations thereunder) of any stock
acquired pursuant to the exercise of ISOs granted under the Plan. A
Disqualifying Disposition is generally any disposition within two years of the
date

<PAGE>

                                      -9-

the ISO was granted or within one year of the date the ISO was exercised,
whichever period ends later.

     19.  Withholding of Additional Income Taxes. Upon the exercise of a
          --------------------------------------
Non-Qualified Option, the grant of an Award, the making of a Purchase of Common
Stock for less than its fair market value, the making of a Disqualifying
Disposition (as defined in paragraph 18), the vesting or transfer of restricted
stock acquired on the exercise of a Stock Right hereunder (or stock or
securities received in a transaction described in Section 424(b) or 424(c)(1)(B)
of the Code), or the making of a distribution or other payment with respect to
such stock or securities, the Company may withhold taxes in respect of amounts
that constitute compensation includible in gross income. The Committee in its
discretion may condition (i) the exercise of an Option, (ii) the grant of an
Award, (iii) the making of a purchase of Common Stock for less than its fair
market value, or (iv) the vesting of restricted Common Stock acquired by
exercising a Stock Right, on the grantee's making satisfactory arrangement for
such withholding. Such arrangement may include payment by the grantee in cash or
by check of the amount of the withholding taxes or, at the discretion of the
Committee, by the grantee's delivery of previously held shares of Common Stock
or the withholding from the shares of Common Stock otherwise deliverable upon
exercise of a Stock Right shares having a fair market value equal as of the date
of exercise to the amount of such withholding taxes.

     20.  Governmental Regulation. The Company's obligation to sell and deliver
          -----------------------
shares of the Common Stock under this Plan is subject to the approval of any
governmental authority required in connection with the authorization, issuance
or sale of such shares.

     In addition to tax withholding, government regulations may impose reporting
or other obligations on the Company with respect to the Plan. For example, the
Company may be required to send tax information statements to employees and
former employees that exercise ISOs.

     21.  Governing Law; Construction. The validity and construction of the Plan
          ---------------------------
and the instruments evidencing Stock Rights shall be governed by the laws of the
Commonwealth of Massachusetts, or the laws of any jurisdiction in which the
Company or its successors in interest may be organized. In construing this Plan,
the singular shall include the plural and the masculine gender shall include the
feminine and neuter, unless the context otherwise requires.<PAGE>

                        WORKGROUP TECHNOLOGY CORPORATION

                                 1996 STOCK PLAN
                                 ---------------

         1.  Purpose. The purpose of the Workgroup Technology Corporation 1996
             -------
Stock Plan (the "Plan") is to encourage key employees of Workgroup Technology
Corporation (the "Company") and of any present or future parent or subsidiary of
the Company (collectively, "Related Corporations") and other individuals who
render services to the Company or a Related Corporation, by providing
opportunities to participate in the ownership of the Company and its future
growth through (a) the grant of options which qualify as "incentive stock
options" ("ISOs") under Section 422(b) of the Internal Revenue Code of 1986, as
amended (the "Code"); (b) the grant of options which do not qualify as ISOs
("Non-Qualified Options"); (c) awards of stock in the Company ("Awards"); and
(d) opportunities to make direct purchases of stock in the Company
("Purchases"). Both ISOs and Non-Qualified Options are referred to hereafter
individually as an "Option" and collectively as "Options." Options, Awards and
authorizations to make Purchases are referred to hereafter collectively as
"Stock Rights." As used herein, the terms "parent" and "subsidiary" mean "parent
corporation" and "subsidiary corporation," respectively, as those terms are
defined in Section 424 of the Code.

         2.  Administration of the Plan.
             --------------------------

             A.  Board or Committee Administration. The Plan shall be
                 ---------------------------------
         administered by the Board of Directors of the Company (the "Board") or
         by a committee appointed by the Board (the "Committee"); provided that
         the Plan shall be administered: (i) to the extent required by
         applicable regulations under Section 162(m) of the Code, by two or more
         "outside directors" (as defined in applicable regulations thereunder)
         and (ii) to the extent required by Rule 16b-3 promulgated under the
         Securities Exchange Act of 1934 or any successor provision ("Rule
         16b-3"), by a disinterested administrator or administrators within the
         meaning of Rule 16b-3. Hereinafter, all references in this Plan to the
         "Committee" shall mean the Board if no Committee has been appointed.
         Subject to ratification of the grant or authorization of each Stock
         Right by the Board (if so required by applicable state law), and
         subject to the terms of the Plan, the Committee shall have the
         authority to (i) determine to whom (from among the class of employees
         eligible under paragraph 3 to receive ISOs) ISOs shall be granted, and
         to whom (from among the class of individuals and entities eligible
         under paragraph 3 to receive Non-Qualified Options and Awards and to
         make Purchases) Non-Qualified Options, Awards and authorizations to
         make Purchases may be granted; (ii) determine the time or times at
         which Options or Awards shall be granted or Purchases made; (iii)
         determine the purchase price of shares subject to each Option or
         Purchase, which prices shall not be less than the minimum price
         specified in paragraph 6; (iv) determine whether each Option granted
         shall be an ISO or a Non-Qualified Option; (v) determine (subject to
         paragraph 7) the time or times when each Option shall become
         exercisable and the duration of the exercise period; (vi) extend the
         period during which outstanding Options may be exercised; (vii)
         determine whether restrictions such as

<PAGE>

                                       -2-

         repurchase options are to be imposed on shares subject to Options,
         Awards and Purchases and the nature of such restrictions, if any, and
         (viii) interpret the Plan and prescribe and rescind rules and
         regulations relating to it. If the Committee determines to issue a
         Non-Qualified Option, it shall take whatever actions it deems
         necessary, under Section 422 of the Code and the regulations
         promulgated thereunder, to ensure that such Option is not treated as an
         ISO. The interpretation and construction by the Committee of any
         provisions of the Plan or of any Stock Right granted under it shall be
         final unless otherwise determined by the Board. The Committee may from
         time to time adopt such rules and regulations for carrying out the Plan
         as it may deem advisable. No member of the Board or the Committee shall
         be liable for any action or determination made in good faith with
         respect to the Plan or any Stock Right granted under it.

             B.  Committee Actions. The Committee may select one of its members
                 -----------------
         as its chairman, and shall hold meetings at such time and places as it
         may determine. A majority of the Committee shall constitute a quorum
         and acts of a majority of the members of the Committee at a meeting at
         which a quorum is present, or acts reduced to or approved in writing by
         all the members of the Committee (if consistent with applicable state
         law), shall be the valid acts of the Committee. From time to time the
         Board may increase the size of the Committee and appoint additional
         members thereof, remove members (with or without cause) and appoint new
         members in substitution therefor, fill vacancies however caused, or
         remove all members of the Committee and thereafter directly administer
         the Plan.

             C.  Grant of Stock Rights to Board Members. Subject to the
                 --------------------------------------
         provisions of the first sentence of paragraph 2(A) above, if
         applicable, Stock Rights may be granted to members of the Board. All
         grants of Stock Rights to members of the Board shall in all other
         respects be made in accordance with the provisions of this Plan
         applicable to other eligible persons. Consistent with the provisions of
         the first sentence of Paragraph 2(A) above, members of the Board who
         either (i) are eligible to receive grants of Stock Rights pursuant to
         the Plan or (ii) have been granted Stock Rights may vote on any matters
         affecting the administration of the Plan or the grant of any Stock
         Rights pursuant to the Plan, except that no such member shall act upon
         the granting to himself or herself of Stock Rights, but any such member
         may be counted in determining the existence of a quorum at any meeting
         of the Board during which action is taken with respect to the granting
         to such member of Stock Rights.

             3.  Eligible Employees and Others. ISOs may be granted only to
                 -----------------------------
employees of the Company or any Related Corporation. Non-Qualified Options,
Awards and authorizations to make Purchases may be granted to any employee,
officer or director (whether or not also an employee) or consultant of the
Company or any Related Corporation. The Committee may take into consideration a
recipient's individual circumstances in determining whether to grant a Stock
Right. The granting of any Stock Right to any individual or entity shall neither
entitle that individual or entity to, nor disqualify such individual or entity
from, participation in any other grant of Stock Rights.

             4.  Stock. The stock subject to Stock Rights shall be authorized
                 -----
but unissued shares of Common Stock of the Company, par value $.01 per share
(the "Common Stock"), or shares of

<PAGE>

                                       -3-

Common Stock reacquired by the Company in any manner. The aggregate number of
shares which may be issued pursuant to the Plan is 3,000,000, subject to
adjustment as provided in paragraph 13. If any Stock Right granted under the
Plan shall expire or terminate for any reason without having been exercised in
full or shall cease for any reason to be exercisable in whole or in part or
shall be repurchased by the Company, the shares of Common Stock subject to such
Stock Right shall again be available for grants of Stock Rights under the Plan.

             No employee of the Company or any Related Corporation may be
granted Options to acquire, in the aggregate, more than 2,000,000 of shares of
Common Stock under the Plan. If any Option granted under the Plan shall expire
or terminate for any reason without having been exercised in full or shall cease
for any reason to be exercisable in whole or in part or shall be repurchased by
the Company, the shares subject to such Option shall be included in the
determination of the aggregate number of shares of Common Stock deemed to have
been granted to such employee under the Plan.

             5.  Granting of Stock Rights. Stock Rights may be granted under the
                 ------------------------
Plan at any time on or after January 26, 1996 and prior to January 26, 2006. The
date of grant of a Stock Right under the Plan will be the date specified by the
Committee at the time it grants the Stock Right; provided, however, that such
date shall not be prior to the date on which the Committee acts to approve the
grant. Options granted under the Plan are intended to qualify as
performance-based compensation to the extent required under Proposed Treasury
Regulation Section 1.162-27.

             6.  Minimum Option Price; ISO Limitations.
                 -------------------------------------

             A.  Price for Non-Qualified Options, Awards and Purchases. The
                 -----------------------------------------------------
         exercise price per share specified in the agreement relating to each
         Non-Qualified Option granted, and the purchase price per share of stock
         granted in any Award or authorized as a Purchase, under the Plan shall
         in no event be less than the minimum legal consideration required
         therefor under the laws of any jurisdiction in which the Company or its
         successors in interest may be organized. Non-Qualified Options granted
         under the Plan, with an exercise price less than the fair market value
         per share of Common Stock on the date of grant, are intended to qualify
         as performance-based compensation under Section 162(m) of the Code and
         any applicable regulations thereunder. Any such Non-Qualified Options
         granted under the Plan shall be exercisable only upon the attainment of
         a pre-established, objective performance goal established by the
         Committee. If the Committee grants Non-Qualified Options with an
         exercise price less than the fair market value per share of Common
         Stock on the date of grant, such grant will be submitted for, and will
         be contingent upon shareholder approval.

             B.  Price for ISOs. The exercise price per share specified in the
                 --------------
         agreement relating to each ISO granted under the Plan shall not be less
         than the fair market value per share of Common Stock on the date of
         such grant. In the case of an ISO to be granted to an employee owning
         stock possessing more than ten percent (10%) of the total combined
         voting power of all classes of stock of the Company or any Related
         Corporation, the price per share specified in the agreement relating to
         such ISO shall not be less than one hundred ten percent (110%) of the
         fair market value per share of Common Stock on the date of

<PAGE>

                                       -4-

         grant. For purposes of determining stock ownership under this
         paragraph, the rules of Section 424(d) of the Code shall apply.

             C.  $100,000 Annual Limitation on ISO Vesting. Each eligible
                 -----------------------------------------
         employee may be granted Options treated as ISOs only to the extent
         that, in the aggregate under this Plan and all incentive stock option
         plans of the Company and any Related Corporation, ISOs do not become
         exercisable for the first time by such employee during any calendar
         year with respect to stock having a fair market value (determined at
         the time the ISOs were granted) in excess of $100,000. The Company
         intends to designate any Options granted in excess of such limitation
         as Non-Qualified Options.

             D.  Determination of Fair Market Value. If, at the time an Option
                 ----------------------------------
         is granted under the Plan, the Company's Common Stock is publicly
         traded, "fair market value" shall be determined as of the date of grant
         or, if the prices or quotes discussed in this sentence are unavailable
         for such date, the last business day for which such prices or quotes
         are available prior to the date of grant and shall mean (i) the average
         (on that date) of the high and low prices of the Common Stock on the
         principal national securities exchange on which the Common Stock is
         traded, if the Common Stock is then traded on a national securities
         exchange; or (ii) the last reported sale price (on that date) of the
         Common Stock on The Nasdaq National Market, if the Common Stock is not
         then traded on a national securities exchange; or (iii) the closing bid
         price (or average of bid prices) last quoted (on that date) by an
         established quotation service for over-the-counter securities, if the
         Common Stock is not reported on the Nasdaq National Market. If the
         Common Stock is not publicly traded at the time an Option is granted
         under the Plan, "fair market value" shall mean the fair value of the
         Common Stock as determined by the Committee after taking into
         consideration all factors which it deems appropriate, including,
         without limitation, recent sale and offer prices of the Common Stock in
         private transactions negotiated at arm's length.

             7.  Option Duration. Subject to earlier termination as provided in
                 ---------------
paragraphs 9 and 10 or in the agreement relating to such Option, each Option
shall expire on the date specified by the Committee, but not more than (i) ten
years from the date of grant in the case of Options generally and (ii) five
years from the date of grant in the case of ISOs granted to an employee owning
stock possessing more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or any Related Corporation, as determined
under paragraph 6(B). Subject to earlier termination as provided in paragraphs 9
and 10, the term of each ISO shall be the term set forth in the original
instrument granting such ISO, except with respect to any part of such ISO that
is converted into a Non-Qualified Option pursuant to paragraph 16.

             8.  Exercise of Option. Subject to the provisions of paragraphs 9
                 ------------------
through 12, each Option granted under the Plan shall be exercisable as follows:

             A.  Vesting. The Option shall either be fully exercisable on the
                 -------
         date of grant or shall become exercisable thereafter in such
         installments as the Committee may specify.

<PAGE>

                                       -5-

             B.     Full Vesting of Installments. Once an installment becomes
                    ----------------------------
         exercisable it shall remain exercisable until expiration or termination
         of the Option, unless otherwise specified by the Committee.

             C.     Partial Exercise. Each Option or installment may be
                    ----------------
         exercised at any time or from time to time, in whole or in part, for up
         to the total number of shares with respect to which it is then
         exercisable.

             D.     Acceleration of Vesting. The Committee shall have the right
                    -----------------------
         to accelerate the date that any installment of any Option becomes
         exercisable; provided that the Committee shall not, without the consent
         of an optionee, accelerate the permitted exercise date of any
         installment of any Option granted to any employee as an ISO (and not
         previously converted into a Non-Qualified Option pursuant to paragraph
         16) if such acceleration would violate the annual vesting limitation
         contained in Section 422(d) of the Code, as described in paragraph
         6(C).

             9.  Termination of Employment. Unless otherwise specified in the
                 -------------------------
agreement relating to such ISO, if an ISO optionee ceases to be employed by the
Company and all Related Corporations other than by reason of death or disability
as defined in paragraph 10, no further installments of his or her ISOs shall
become exercisable, and his or her ISOs shall terminate on the earlier of (a)
ninety (90) days after the date of termination of his or her employment, or (b)
their specified expiration dates, except to the extent that such ISOs (or
unexercised installments thereof) have been converted into Non-Qualified Options
pursuant to paragraph 16. For purposes of this paragraph 9, employment shall be
considered as continuing uninterrupted during any bona fide leave of absence
(such as those attributable to illness, military obligations or governmental
service) provided that the period of such leave does not exceed 90 days or, if
longer, any period during which such optionee's right to reemployment is
guaranteed by statute. A bona fide leave of absence with the written approval of
the Committee shall not be considered an interruption of employment under this
paragraph 9, provided that such written approval contractually obligates the
Company or any Related Corporation to continue the employment of the optionee
after the approved period of absence. ISOs granted under the Plan shall not be
affected by any change of employment within or among the Company and Related
Corporations, so long as the optionee continues to be an employee of the Company
or any Related Corporation. Nothing in the Plan shall be deemed to give any
grantee of any Stock Right the right to be retained in employment or other
service by the Company or any Related Corporation for any period of time.

             10. Death; Disability.
                 -----------------

             A.     Death. If an ISO optionee ceases to be employed by the
                    -----
         Company and all Related Corporations by reason of his or her death, any
         ISO owned by such optionee may be exercised, to the extent otherwise
         exercisable on the date of death, by the estate, personal
         representative or beneficiary who has acquired the ISO by will or by
         the laws of descent and distribution, until the earlier of (i) the
         specified expiration date of the ISO or (ii) 180 days from the date of
         the optionee's death.

<PAGE>

                                      -6-

         B.  Disability. If an ISO optionee ceases to be employed by the Company
             ----------
      and all Related Corporations by reason of his or her disability, such
      optionee shall have the right to exercise any ISO held by him or her on
      the date of termination of employment, for the number of shares for which
      he or she could have exercised it on that date, until the earlier of (i)
      the specified expiration date of the ISO or (ii) 180 days from the date of
      the termination of the optionee's employment. For the purposes of the
      Plan, the term "disability" shall mean "permanent and total disability" as
      defined in Section 22(e)(3) of the Code or any successor statute.

         11. Assignability. No Stock Right shall be assignable or transferable
             -------------
by the grantee except by will, by the laws of descent and distribution or, in
the case of Non-Qualified Options only, pursuant to a valid domestic relations
order. Except as set forth in the previous sentence, during the lifetime of a
grantee each Stock Right shall be exercisable only by such grantee.

         12. Terms and Conditions of Options. Options shall be evidenced by
             -------------------------------
instruments (which need not be identical) in such forms as the Committee may
from time to time approve. Such instruments shall conform to the terms and
conditions set forth in paragraphs 6 through 11 hereof and may contain such
other provisions as the Committee deems advisable which are not inconsistent
with the Plan, including restrictions applicable to shares of Common Stock
issuable upon exercise of Options. The Committee may specify that any
Non-Qualified Option shall be subject to the restrictions set forth herein with
respect to ISOs, or to such other termination and cancellation provisions as the
Committee may determine. The Committee may from time to time confer authority
and responsibility on one or more of its own members and/or one or more officers
of the Company to execute and deliver such instruments. The proper officers of
the Company are authorized and directed to take any and all action necessary or
advisable from time to time to carry out the terms of such instruments.

         13. Adjustments. Upon the occurrence of any of the following events, an
             -----------
optionee's rights with respect to Options granted to such optionee hereunder
shall be adjusted as hereinafter provided, unless otherwise specifically
provided in the written agreement between the optionee 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 Options 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.

         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 Committee 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

<PAGE>

                                       -7-

      Options by substituting on an equitable basis for the shares then subject
      to such Options either (a) the consideration payable with respect to the
      outstanding shares of Common Stock in connection with the Acquisition, (b)
      shares of stock of the surviving corporation or (c) such other securities
      as the Successor Board deems appropriate, the fair market value of which
      shall not materially exceed the fair market value of the shares of Common
      Stock subject to such Options immediately preceding the Acquisition; or
      (ii) upon written notice to the optionees, provide that all Options must
      be exercised, to the extent then exercisable, 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 (to the extent then exercisable) 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, an optionee 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 subparagraphs A, B or C with respect to ISOs shall be
      made only after the Committee, 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 of the
      Code) or would cause any adverse tax consequences for the holders of such
      ISOs. If the Committee determines that such adjustments made with respect
      to ISOs would constitute a modification of such ISOs or would cause
      adverse tax consequences to the holders, it may refrain from making such
      adjustments.

         E. Dissolution or Liquidation. In the event of the proposed dissolution
            --------------------------
      or liquidation of the Company, each Option will terminate immediately
      prior to the consummation of such proposed action or at such other time
      and subject to such other conditions as shall be determined by the
      Committee.

         F. 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. No adjustments shall be made for
      dividends paid in cash or in property other than securities of the
      Company.

         G. Fractional Shares. No fractional shares shall be issued under the
            -----------------
      Plan and the optionee shall receive from the Company cash in lieu of such
      fractional shares.

         H. Adjustments. Upon the happening of any of the events described in
            -----------
      subparagraphs A, B or C above, the class and aggregate number of shares
      set forth in paragraph 4 hereof that are subject to Stock Rights which
      previously have been or

<PAGE>

                                      -8-

      subsequently may be granted under the Plan shall also be appropriately
      adjusted to reflect the events described in such subparagraphs. The
      Committee or the Successor Board shall determine the specific adjustments
      to be made under this paragraph 13 and, subject to paragraph 2, its
      determination shall be conclusive.

         14. Means of Exercising Options. An Option (or any part or installment
             ---------------------------
thereof) shall be exercised by giving written notice to the Company at its
principal office address, or to such transfer agent as the Company shall
designate. Such notice shall identify the Option being exercised and specify the
number of shares as to which such Option is being exercised, accompanied by full
payment of the purchase price therefor either (a) in United States dollars in
cash or by check, (b) at the discretion of the Committee, 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, (c) at the discretion of the
Committee, by delivery of the grantee's personal recourse note bearing interest
payable not less than annually at no less than 100% of the lowest applicable
Federal rate, as defined in Section 1274(d) of the Code, (d) at the discretion
of the Committee and consistent with applicable law, through the delivery of an
assignment to the Company of a sufficient amount of the proceeds from the sale
of the Common Stock acquired upon exercise of the Option and an authorization to
the broker or selling agent to pay that amount to the Company, which sale shall
be at the participant's direction at the time of exercise, or (e) at the
discretion of the Committee, by any combination of (a), (b), (c) and (d) above.
If the Committee exercises its discretion to permit payment of the exercise
price of an ISO by means of the methods set forth in clauses (b), (c), (d) or
(e) of the preceding sentence, such discretion shall be exercised in writing at
the time of the grant of the ISO in question. The holder of an Option shall not
have the rights of a shareholder with respect to the shares covered by such
Option until the date of issuance of a stock certificate to such holder for such
shares. Except as expressly provided above in paragraph 13 with respect to
changes in capitalization and stock dividends, no adjustment shall be made for
dividends or similar rights for which the record date is before the date such
stock certificate is issued.

         15. Term and Amendment of Plan. This Plan was adopted by the Board on
             --------------------------
January 26, 1996, subject, with respect to the validation of ISOs granted under
the Plan, to approval of the Plan by the stockholders of the Company at the next
Meeting of Stockholders or, in lieu thereof, by written consent. If the approval
of stockholders is not obtained prior to January 26, 1997, any grants of ISOs
under the Plan made prior to that date will be rescinded. The Plan shall expire
at the end of the day on January 26, 2006 (except as to Options outstanding on
that date). Subject to the provisions of paragraph 5 above, Options may be
granted under the Plan prior to the date of stockholder approval of the Plan.
The Board may terminate or amend the Plan in any respect at any time, except
that, without the approval of the stockholders obtained within 12 months before
or after the Board adopts a resolution authorizing any of the following actions:
(a) the total number of shares that may be issued under the Plan may not be
increased (except by adjustment pursuant to paragraph 13); (b) the benefits
accruing to participants under the Plan may not be materially increased; (c) the
requirements as to eligibility for participation in the Plan may not be
materially modified; (d) the provisions of paragraph 3 regarding eligibility for
grants of ISOs may not be modified; (e) the provisions of paragraph 6(B)
regarding the exercise price at which shares may be offered pursuant to ISOs may
not be modified (except by adjustment pursuant to paragraph 13); (f) the
expiration date of the Plan may not be extended;

<PAGE>

                                      -9-

and (g) the Board may not take any action which would cause the Plan to fail to
comply with Rule 16b-3. Except as otherwise provided in this paragraph 15, in no
event may action of the Board or stockholders alter or impair the rights of a
grantee, without such grantee's consent, under any Option previously granted to
such grantee.

         16. Conversion of ISOs into Non-Qualified Options. The Committee, at
             ---------------------------------------------
the written request or with the written consent of any optionee, may in its
discretion take such actions as may be necessary to convert such optionee's ISOs
(or any installments or portions of installments 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 optionee is an
employee of the Company or a Related Corporation at the time of such conversion.
Such actions may include, but shall not be limited to, extending the exercise
period or reducing the exercise price of the appropriate installments of such
ISOs. At the time of such conversion, the Committee (with the consent of the
optionee) may impose such conditions on the exercise of the resulting
Non-Qualified Options as the Committee 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 optionee the right to have such optionee's ISOs
converted into Non-Qualified Options, and no such conversion shall occur until
and unless the Committee takes appropriate action.

         17. Application Of Funds. The proceeds received by the Company from the
             --------------------
sale of shares pursuant to Options granted and Purchases authorized under the
Plan shall be used for general corporate purposes.

         18. Notice to Company of Disqualifying Disposition. By accepting an ISO
             ----------------------------------------------
granted under the Plan, each optionee agrees to notify the Company in writing
immediately after such optionee makes a Disqualifying Disposition (as described
in Sections 421, 422 and 424 of the Code and regulations thereunder) of any
stock acquired pursuant to the exercise of ISOs granted under the Plan. A
Disqualifying Disposition is generally any disposition occurring on or before
the later of (a) the date two years following the date the ISO was granted or
(b) the date one year following the date the ISO was exercised.

         19. Withholding of Additional Income Taxes. Upon the exercise of a
             --------------------------------------
Non-Qualified Option, the grant of an Award, the making of a purchase of Common
Stock for less than its fair market value, the making of a Disqualifying
Disposition (as defined in paragraph 18), the vesting or transfer of restricted
stock or securities acquired on the exercise of an Option hereunder, or the
making of a distribution or other payment with respect to such stock or
securities, the Company may withhold taxes in respect of amounts that constitute
compensation includible in gross income. The Committee in its discretion may
condition (i) the exercise of an Option, (ii) the grant of an Award, (iii) the
making of a Purchase of Common Stock for less than its fair market value, or
(iv) the vesting or transferability of restricted stock or securities acquired
by exercising an Option, on the grantee's making satisfactory arrangement for
such withholding. Such arrangement may include payment by the grantee in cash or
by check of the amount of the withholding taxes or, at the discretion of the
Committee, by the grantee's delivery of previously held shares of Common Stock
or the withholding from the shares of Common Stock otherwise deliverable upon
exercise of a Option shares having an aggregate fair market value equal to the
amount of such withholding taxes.

         20. Governmental Regulation. The Company's obligation to sell and
             -----------------------
deliver shares of the Common Stock under this Plan is subject to the approval of
any governmental authority required in connection with the authorization,
issuance or sale of such shares.

         Government regulations may impose reporting or other obligations on the
Company with respect to the Plan. For example, the Company may be required to
send tax information statements to employees and former employees that exercise
ISOs under the Plan, and the Company may be required to file tax information
returns reporting the income received by grantees of Options in connection with
the Plan.

         21. Governing Law. The validity and construction of the Plan and the
             -------------
instruments evidencing Options shall be governed by the laws of the Commonwealth
of Massachusetts.
