                                 PURPOSE OF PLAN

         OpenSite Technologies, Inc. has adopted this employee stock purchase
plan to encourage the employees of the Company (and its participating affiliated
companies) to acquire a proprietary interest, or to increase their existing
proprietary interest, in the Company. The Board of Directors of the Company
believes that employee ownership of the Company's stock will serve as an
incentive, encouraging employees to continue their employment and to perform
diligently their duties as employees. It is further intended that the Plan
qualify as an "employee stock purchase plan" within the meaning of Code ss.423.

                           (iv)     If, for any reason, the Fair Market Value
                  per share cannot be ascertained or is unavailable for the date
                  in question, the Fair Market Value per share shall be

                  Market Value can be ascertained under the appropriate method
                  indicated above.

                  (c)      Notwithstanding the above provisions, for purposes of
         making purchases under the Plan during the initial Offering Period, the

         3.1      PARTICIPATION BY ELIGIBLE EMPLOYEES. An Eligible Employee of a
Participating Company shall be eligible to participate in the Plan as of the

                             ELECTION TO PARTICIPATE

         5.1      ELECTION. Each Employee who is eligible to participate in the
Plan may file with the Committee, on or before 5:00 p.m. on any Enrollment Date
(within such time period as provided by the Committee), an election form
authorizing specified regular payroll deductions over the next succeeding
Offering Period. These payroll deductions shall be on an after-tax basis, so
that all applicable federal, state, local and Social Security taxes shall apply.
At the time an Employee files his election form, he shall elect to have payroll
deductions made on each payday during the Offering Period, in whole dollars, in
an amount which is not greater than twenty percent (20%) of such Employee's
Total Pay for each payroll period occurring during said Offering Period. No cash
contributions or payments may be made by an Employee to the Plan. Payroll
deductions for an Employee shall commence on the first payroll period beginning
after the Offering Commencement Date (or, in lieu of the Offering Commencement
Date for the initial Offering Period, any date specified by the Employee
occurring during the period beginning with the date on which the initial
registration statement registering the shares of Common Stock issuable hereunder
pursuant to the Securities Act of 1933, as amended, is declared effective, and
ending with the Enrollment Date), and shall end on the last payroll in the
Offering Period before the Offering Exercise Date, to which such authorization
is applicable, unless sooner terminated by the Employee.

         5.2      DEEMED ELECTION. An Employee who has entered into a written
agreement with the Company not to be eligible for participation in this Plan
and/or any employee benefit plans of the Company shall, by entering into such
written agreement, automatically be considered to have elected to have none of
his pay deducted under this Plan during any Offering Period which begins while
such written agreement is in effect.

         5.3      ACCOUNTS. The Committee shall establish a bookkeeping account
for each Employee in the Plan and shall credit each Employee's payroll
deductions to his account. Any funds actually held in Accounts shall remain part
of the general assets of the Company and may be used by the Company for any
corporate purpose.

         5.4      WITHDRAWALS. By written notice to the Committee during an
Offering Period (on such form or in such manner as the Committee may specify),
an Employee may elect to cease his payroll deductions and withdraw, effective as
of the Offering Exercise Date of such Offering Period, the total amount (but not
less than the total amount) credited to his Account. Any such withdrawn amount
shall be paid to the Employee, in cash or its equivalent, without interest, as
promptly as administratively practicable after such Offering Exercise Date. An
Employee who elects to withdraw the total amount credited to his Account shall
cease participation in the Plan as of the Offering Exercise Date and shall not
participate again until the second Offering Commencement Date following such
Offering Exercise Date, provided he files an election form with the Committee on
or before the Enrollment Date for such second succeeding Offering Commencement
Date. Payroll deductions shall cease as soon as administratively practicable
after the Committee receives such election, and any option granted to the
Employee under the Plan shall terminate on the date the Committee receives such
election.

         5.5      Modifications. By written notice to the Committee (on such
form or in such manner as the Committee may specify), an Employee may elect to
modify his payroll deductions and increase or decrease (but not to zero) the
amount to be withheld from his pay and credited to his Account during such
Offering Period under the Plan effective for each payroll period occurring on or
after the receipt by the Committee of such election or as soon thereafter as
administratively practicable.

         5.6      LEAVE OF ABSENCE. For purposes of participation in the Plan,
an Employee who is on a leave of absence shall be deemed to be an Employee for
the first ninety (90) days of such leave of absence; provided, that as of the
close of business on the 90th day of such leave of absence, the Employee's
employment (solely for purposes of the Plan) shall be deemed to have terminated
unless the

                                      -4-
<PAGE>   5

Employee shall have returned to his regular employment prior to the close of
business on such 90th day, except as otherwise required by law. If an Employee's
employment is terminated earlier by the Company, for any reason, his right to
participate in the Plan shall terminate simultaneously.

         5.7      INTEREST. No interest will accrue or be paid on any payroll
deductions contributed to the Plan or credited to the Account of any Employee.

                                   ARTICLE VI
                               GRANTING OF OPTIONS

         6.1      NUMBER OF OPTION SHARES. On each Offering Commencement Date,
each eligible Employee shall be granted an option to purchase a maximum number
of shares of the Common Stock determined by dividing twenty percent (20%) of his
Offering Period Pay by eighty-five percent (85%) of the Fair Market Value of one
share of the Common Stock on such Offering Commencement Date.

         6.2      DURATION. Each option granted on an Offering Commencement Date
shall terminate on the immediately following Offering Exercise Date, unless
terminated earlier pursuant to the terms of the Plan.

         6.3      ANNUAL LIMIT ON OPTIONS GRANTED. No option to purchase shares
under the Plan shall be granted to an Employee if such option, when combined
with all other options granted under all of the Code ss. 423 employee stock
purchase plans of the Company, its parents and its subsidiary corporations,
would permit such Employee to purchase shares of the Common Stock with a Fair
Market Value (determined at the time the option is granted) in excess of $25,000
for each calendar year in which the option is outstanding at any time,
determined in accordance with Code ss.423(b)(8).

         6.4      OPTION EXERCISE PRICE. The Option Exercise Price of each share
of the Common Stock shall be the lesser of (i) eighty-five percent (85%) of the
Fair Market Value of such share on the Offering Commencement Date, or (ii)
eighty-five (85%) of the Fair Market Value of such share on the Offering
Exercise Date.

                                  ARTICLE VII
                               EXERCISE OF OPTIONS

         7.1      AUTOMATIC PURCHASE. As of each Offering Exercise Date and
except as provided in Sections 7.2 and 7.3 hereof, the Committee shall purchase,
for each Employee having funds credited to his Account, the number of whole
shares of the Common Stock which is the lesser of (i) the maximum number of such
shares for which such Employee has been granted an option to purchase during
such Offering Period, or (ii) the number of whole shares of the Common Stock
determined by dividing the amount credited to his Account by the Option Exercise
Price. Fractional shares shall be issued in the Employee's Account, but upon a
distribution of shares from the Employee's Account, fractional shares shall be
distributed in the form of cash based on the Fair Market Value at liquidation of
such shares, with liquidation to occur in accordance with the Plan's
administrative practices.

         7.2      EMPLOYEE ELECTION. Notwithstanding any provisions to the
contrary contained herein, by giving written notice to the Committee during an
Offering Period (at such time or in such manner as the Committee may direct), an
Employee may elect, effective as of the Offering Exercise Date of such Offering
Period, to exercise his option for a specified number of full shares, not less
than 5, but less than the anticipated number of full shares of the Common Stock
which the Committee otherwise would purchase for him pursuant to the terms of
Section 7.1 hereof. If an Employee makes such an election, the shares of the
Common Stock which he has elected to purchase will be delivered to him, and the
balance of his accumulated payroll deductions credited to his Account will be

                                      -5-
<PAGE>   6

paid to him, in cash or its equivalent and without interest, as soon as
practicable after the Offering Exercise Date of such Offering Period in which
such election is made. An Employee who elects to exercise his option for less
than the full anticipated number of shares shall cease to participate in the
Plan following such Offering Exercise Date and shall not participate again until
the second Offering Commencement Date following such Offering Exercise Date,
provided he files an election form with the Committee on or before the
Enrollment Date for such second Offering Commencement Date.

         7.3      MAXIMUM DOLLAR AMOUNT OF COMMON STOCK PURCHASED.
Notwithstanding any provisions to the contrary contained herein, no Employee may
use the amount credited to his Account pursuant to the Plan during any calendar
year for purchase of Common Stock exceeding twenty-five thousand dollars
($25,000) in Fair Market Value (determined as of the Offering Commencement
Date). When this amount of Common Stock has been purchased, any excess amount
credited to an Employee's Account (including any excess resulting from an
inability to purchase a whole share) shall be returned to such Employee, payroll
deductions for such Employee shall cease, and such Employee shall be ineligible
to participate in any subsequent Offering Period occurring during that same
calendar year. Such Employee's election automatically shall become effective on
the first Offering Commencement Date of the next succeeding calendar year,
subject to the termination provisions herein.

                                  ARTICLE VIII
                  DELIVERY OF COMMON STOCK; SHAREHOLDER RIGHTS

         As soon as practicable after each Offering Exercise Date, the Company
shall issue and deliver to each Employee certificates representing the shares of
the Common Stock, if any, purchased for such Employee, together with any cash to
which he may be entitled hereunder. Upon issuance of such certificates (but not
prior thereto), the Employee shall have all of the rights and privileges of a
shareholder of the Company with respect to such shares. Common Stock to be
delivered to an Employee pursuant to the Plan shall be registered in the name of
the Employee.

                                   ARTICLE IX
                           STOCK RESERVED FOR OPTIONS

         9.1      SHARES RESERVED FOR ISSUANCE UNDER THE PLAN. The Company shall
reserve a total of seven hundred thousand (700,000) shares of the Common Stock
for issuance and purchase by Employees under the Plan; provided, however, this
total number of shares of Common Stock that may be issued pursuant to this Plan
shall be automatically increased on the last trading day of the final calendar
month of each fiscal year of the Company, beginning with the fiscal year ending
December 31, 2001, by a number of shares equal to one percent (1%) of the number
of shares of Common Stock outstanding on the last trading day of the month
preceding the such final calendar month, but in no event shall any such annual
increase exceed three hundred thousand (300,000) shares. The number of shares of
the Common Stock reserved for the Plan may be further adjusted as provided in
Article XII. The shares of the Common Stock reserved for the Plan may be shares
now or hereafter authorized but unissued or may be shares of treasury stock.

         9.2      SHARES SUBJECT TO UNEXERCISED OPTIONS. If and to the extent
that any right to purchase reserved shares of the Common Stock shall not be
exercised by the Employee who is the holder of such right, or if such right
shall terminate as provided herein, then the shares subject to such right to
purchase (i) shall again become available for purposes of the Plan, and (ii)
shall not be deemed to increase the number of shares of the Common Stock
reserved for purposes of the Plan.

                                   ARTICLE X

         and/or accounting and crediting procedures to ensure that amounts
         applied toward the purchase of Company Stock for each Employee properly
         correspond with amounts withheld from the Employee's paychecks; and

                  (d)      establish such other limitations or procedures as it
         may determine, in its sole discretion, advisable which are consistent
         with the terms of the Plan.

Common Stock reserved or authorized to be reserved under the Plan and the number
and price of such shares subject to purchase pursuant to options outstanding
hereunder, in the sole discretion of the Committee, may be adjusted in such

liquidation, or merger or consolidation in which the Company is not the
surviving corporation.

         12.3     RIGHTS OF EMPLOYEES. Except as hereinabove expressly provided,
no Employee shall have any rights by reason of any subdivision or consolidation
of shares of stock of any class or any other increase or decrease in the number
of shares of stock of any class by reason of any dissolution, liquidation,
merger or consolidation or spin-off of the assets or stock of another
corporation; and any issue by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number or
price of shares of the Common Stock subject to the option. The grant of an
option pursuant to the Plan shall not affect in any way the right or power of
the Company to make adjustments, reclassifications, reorganizations or changes
of its capital or business structure or to merge or to consolidate or to
dissolve, liquidate or sell, or transfer all or any part of its business or
assets.

termination of employment (for any reason other than death) during a Offering
Period (other than the last day of such Offering Period), any option granted to
him under the Plan shall terminate immediately upon the date his employment
ends, and the amount credited to his Account shall be refunded to him in cash as
soon as administratively practicable after the earlier of (1) the Offering
Exercise Date of such Offering Period, or (2) the payroll period next following
the termination of employment.

         13.2     DEATH. In the event of an Employee's death during a Offering
Period (other than the last day of such Offering Period), any option granted to
him under the Plan for such Offering Period shall terminate immediately upon the
date of his death, and the amount credited to his Account for such Offering
Period shall be paid in cash to the person(s) designated as his beneficiary as
soon as administratively practicable following the earlier of (1) the Offering
Exercise Date of such Offering Period, or (2) the payroll period next following
his termination of employment. Also, in the event any shares of the Common Stock
and/or any cash is payable to the deceased Employee with respect to an Offering
Period ending on or before his date of death, such shares and/or cash shall be
paid to the person(s) designated as his beneficiary.

         13.3     BENEFICIARY. An Employee may file with the Committee a written
designation of a beneficiary who is to receive any Common Stock or cash pursuant
to the Plan in the event of the death of such Employee prior to delivery to him
of such Common Stock or cash. Such designation of beneficiary may be changed by
the Employee, and upon receipt by the Committee of proof of the identity at the
Employee's death of a beneficiary validly designated by him pursuant to the
Plan, the Company shall deliver such Common Stock or cash to such beneficiary.
In the absence of a validly-designated beneficiary who is living at the time of
such Employee's death, the Company shall deliver such Common Stock or cash to
the estate of such Employee. No designated beneficiary shall, prior to the death
of the Employee by whom he has been designated, acquire any interest in the
Common Stock or cash which may be credited to the account of the Employee under
the Plan. Any decision by the Committee as to the person or persons to whom to
distribute the Common Stock or cash shall be binding and shall not create any
liability whatsoever on the part of the Company or the Committee or its members.

         5.3      DELEGATION OF AUTHORITY. The Board may delegate its authority
under the Plan, in whole or in part, to a Committee appointed by the Board
consisting of not less than two (2) directors. The members of the Committee
shall be appointed from time to time by, and shall serve at the discretion of,
the Board. If the Board or Committee so chooses, the Board or Committee may
delegate its authority under the Plan, in whole or in part, to two or more
members of management. Any delegate to which Board authority under this Plan has
been properly delegated shall act according to the policies and procedures set
forth in the Plan and to those policies and procedures established by the Board
or by such delegate, and such delegate shall have such powers and
responsibilities as are set forth by the delegating party. Reference to the
Board in this Plan shall specifically include reference to any delegate to which
Board authority under this Plan has been properly delegated where Board
authority has been delegated to such delegate, and any action by such delegate
pursuant to a delegation of

             OpenSite Technologies, Inc. 2000 Stock Incentive Plan
                                  Page 4 of 13

<PAGE>   5

authority shall be deemed an action by the Board under the Plan. Notwithstanding
the above, the Board may assume the powers and responsibilities granted to a
delegate at any time, in whole or in part. With respect to Committee
appointments and composition, only a Committee (or a sub-committee thereof)
comprised solely of two (2) or more Outside Directors may grant Stock Incentives
which will meet the Performance-Based Exception, and only a Committee comprised
solely of Outside Directors may grant Stock Incentives to Insiders that will be
exempt from Section 16(b) of the Exchange Act.

         5.4      DECISIONS BINDING. All determinations and decisions made by
the Board or a delegate pursuant to the provisions of this Plan and all related
orders and resolutions of the Board or a delegate shall be final, conclusive and
binding on all persons, including the Company, its stockholders, Directors,
Employees, Key Persons, Participants, and their estates and beneficiaries

         5.5      INDEMNIFICATION FOR DECISIONS. No member of the Board or any
delegate shall be liable for any action taken or determination made hereunder in
good faith. Service on the Committee or otherwise as a delegate shall constitute
service as a director of the Company so that the members of the Committee or a
delegate shall be entitled to indemnification and reimbursement as directors of
the Company pursuant to its bylaws and applicable law.

                                   SECTION 6.
                                  ELIGIBILITY

         Employees and Key Persons selected by the Board shall be eligible for
the grant of Stock Incentives under this Plan, but no Employee or Key Person
shall have the right to be granted a Stock Incentive under this Plan merely as a
result of his or her status as an Employee or Key Person. Only Employees shall
be eligible to receive a grant of ISO's.

                                   SECTION 7.
                           TERMS OF STOCK INCENTIVES

         7.1      TERMS AND CONDITIONS OF ALL STOCK INCENTIVES.

                  (a) The Board, in its absolute discretion, shall grant Stock
Incentives under this Plan from time to time and shall have the right to grant
new Stock Incentives in exchange for outstanding Stock Incentives. Stock
Incentives shall be granted to Employees or Key Persons selected by the Board,
and the Board shall be under no obligation whatsoever to grant Stock Incentives
to all Employees or Key Persons, or to grant all Stock Incentives subject to the
same terms and conditions.

                  (b) The number of Shares as to which a Stock Incentive shall
be granted shall be determined by the Board in its sole discretion, subject to
the provisions of Section 3 as to the total number of shares available for
grants under the Plan.

                  (c) Each Stock Incentive shall be evidenced by a Stock
Incentive Agreement executed by the Company and the Participant, which shall be
in such form and contain such terms and conditions as the Board in its
discretion may, subject to the provisions of the Plan, from time to time
determine.

                  (d) The date a Stock Incentive is granted shall be the date on
which the Board has approved the terms and conditions of the Stock Incentive
Agreement and has determined the recipient of the Stock Incentive and the number
of Shares covered by the Stock Incentive and has taken all such other action
necessary to complete the grant of the Stock Incentive.

         7.2      TERMS AND CONDITIONS OF OPTIONS. Each grant of an Option shall
be evidenced by a Stock Incentive Agreement which shall specify whether the
Option is an ISO or Non-ISO and incorporate such other terms and conditions as
the Board, acting in its absolute discretion, deems consistent with the terms of
this Plan, including (without limitation) a restriction on the number of Shares
subject to the Option which first become exercisable or subject to surrender
during any calendar year.

             OpenSite Technologies, Inc. 2000 Stock Incentive Plan
                                  Page 5 of 13

<PAGE>   6

                  The Board and/or the Company shall have complete discretion,
notwithstanding subsection (a) above, to modify the terms and provisions of an
Option in accordance with Section 13 of this Plan even though such modification
may change the Option form an ISO to Non-ISO.

                  In determining Employee(s) or Key Person(s) to whom an Option
shall be granted and the number of Shares to be covered by such Option, the
Board may take into account the recommendations of the Chief Executive Officer
of the Company and its other officers, the duties of the Employee or Key Person,
the present and potential contributions of the Employee or Key Person to the
success of the Company, the anticipated number of years of service remaining
before the attainment by the Employee of retirement age, and other factors
deemed relevant by the Board, in its sole discretion, in connection with
accomplishing the purpose of this Plan. An Employee or Key Person who has been
granted an Option to purchase Shares, whether under this Plan or otherwise, may
be granted one or more additional Options. If the Board grants an ISO and a
Non-ISO to an Employee on the same date, the right of the Employee to exercise
or surrender one such Option shall not be conditioned on his or her failure to
exercise or surrender the other such Option.

                  (a) EXERCISE PRICE. Subject to adjustment in accordance with
Section 11 and the other provisions of this Section, the Exercise Price shall be
as set forth in the applicable Stock Incentive Agreement. With respect to each
grant of an ISO to a Participant who is not a Ten Percent Shareholder, the
Exercise Price shall not be less than the Fair Market Value on the date the ISO
is granted. With respect to each grant of an ISO to a Participant who is a Ten
Percent Shareholder, a Ten Percent Shareholder shall not be less than one
hundred ten percent (110%) of the Fair Market Value on the date the ISO is
granted. If a Stock Incentive is a Non-ISO, the Exercise Price for each Share
shall be no less than the minimum price required by applicable state law, or by
the Company's governing instrument, or $0.01, whichever price is greater. Any
Stock Incentive intended to meet the Performance-Based Exception must be granted
with an Exercise Price equivalent to or greater than the Fair Market Value of
the Shares subject thereto.

                  (b) OPTION TERM. Each Option granted under this Plan shall be
exercisable in whole or in part at such time or times as set forth in the
related Stock Incentive Agreement, but no Stock Incentive Agreement shall:

                      (i)   make an Option exercisable before the date such
                            Option is granted; or

                      (ii)  make an Option exercisable after the earlier of:

                            (A) the date such Option is exercised in full, or

                            (B) the date which is the tenth (10th) anniversary
of the date such Option is granted, if such Option is a Non-ISO or an ISO
granted to a non-Ten Percent Shareholder, or the date which is the fifth (5th)
anniversary of the date such Option is granted, if such Option is an ISO granted
to a Ten Percent Shareholder.

         A        Stock Incentive Agreement may provide for the exercise of an
Option after the employment of an Employee has terminated for any reason
whatsoever, including death or disability. The Employee's rights, if any, upon
termination of employment will be set forth in the applicable Stock Incentive
Agreement.

                  (c) PAYMENT. Options shall be exercised by the delivery of a
written notice of exercise to the Company, setting forth the number of Shares
with respect to which the Option is to be exercised accompanied by full payment
for the Shares. Payment for shares of Stock purchased pursuant to exercise of an
Option shall be made in cash or, unless the Stock Incentive Agreement provides
otherwise, by delivery to the Company of a number of Shares which have been
owned and completely paid for by the holder for at least six (6) months prior to
the date of exercise (I.E., "mature shares" for accounting purposes) having an

             OpenSite Technologies, Inc. 2000 Stock Incentive Plan
                                  Page 6 of 13

<PAGE>   7

aggregate Fair Market Value equal to the amount to be tendered, or a combination
thereof. In addition, unless the Stock Incentive Agreement provides otherwise,
the Option may be exercised through a brokerage transaction following
registration of the Company's equity securities under Section 12 of the
Securities Exchange Act of 1934 as permitted under the provisions of Regulation
T applicable to cashless exercises promulgated by the Federal Reserve Board.
However, notwithstanding the foregoing, with respect to any Option recipient who
is an Insider, a tender of shares or a cashless exercise must (1) have met the
requirements of an exemption under Rule 16b-3 promulgated under the Exchange
Act, or (2) be a subsequent transaction the terms of which were provided for in
a transaction initially meeting the requirements of an exemption under Rule
16b-3 promulgated under the Exchange Act. Unless the Stock Incentive Agreement
provides otherwise, the foregoing exercise payment methods shall be subsequent
transactions approved by the original grant of an Option. Except as provided in
subparagraph (f) below, payment shall be made at the time that the Option or any
part thereof is exercised, and no Shares shall be issued or delivered upon
exercise of an Option until full payment has been made by the Participant. The
holder of an Option, as such, shall have none of the rights of a stockholder.

                  Notwithstanding the above, and in the sole discretion of the
Board, an Option may be exercised as to a portion or all (as determined by the
Board) of the number of Shares specified in the Stock Incentive Agreement by
delivery to the Company of a promissory note, such promissory note to be
executed by the Participant and which shall include, with such other terms and
conditions as the Board shall determine, provisions in a form approved by the
Board under which: (i) the balance of the aggregate purchase price shall be
payable in equal installments over such period and shall bear interest at such
rate (which shall not be less than the prime bank loan rate as determined by the
Board) as the Board shall approve, and (ii) the Participant shall be personally
liable for payment of the unpaid principal balance and all accrued but unpaid
interest. Other methods of payment may also be used if approved by the Board in
its sole and absolute discretion and not prohibited under the Stock Incentive
Agreement.

                  (d) CONDITIONS TO EXERCISE OF AN OPTION. Each Option granted
under the Plan shall vest and shall be exercisable at such time or times, or
upon the occurrence of such event or events, and in such amounts, as the Board
shall specify in the Stock Incentive Agreement; provided, however, that
subsequent to the grant of an Option, the Board, at any time before complete
termination of such Option, may accelerate the time or times at which such
Option may vest or be exercised in whole or in part. The Board may impose such
restrictions on any Shares acquired pursuant to the exercise of an Option as it
may deem advisable, including, without limitation, vesting or performance-based
restrictions, restrictions under applicable federal securities laws, under the
requirements of any stock exchange or market upon which such Shares are then
listed and/or traded, and under any blue sky or state securities laws applicable
to such Shares.

                  (e) TRANSFERABILITY OF OPTIONS. An Option shall not be
transferable or assignable except by will or by the laws of descent and
distribution and shall be exercisable, during the Participant's lifetime, only
by the Participant, or in the event of the disability of the Participant;
provided, however, that in the event the Participant is incapacitated and unable
to exercise his or her Option, such Option may be exercised by such
Participant's legal guardian, legal representative, or other representative whom
the Board deems appropriate based on applicable facts and circumstances. The
determination of incapacity of a Participant and the determination of the
appropriate representative of the Participant who shall be able to exercise the
Option if the Participant is incapacitated shall be determined by the Board in
its sole and absolute discretion. Notwithstanding the foregoing, a Non-ISO may
also be transferred as a bona fide gift (i) to his spouse or lineal descendant
or lineal ascendant, (ii) to a trust for the benefit of one or more individuals
described in clause (i), (iii) to a partnership of which the only partners are
one or more individuals described in clause (i), or (iv) to other persons with
the prior approval of the Board in its sole and absolute discretion, in which
case the transferee shall be subject to all provisions of the Plan, the Stock
Incentive Agreement and the Exercise and Shareholder Agreement provided by the
Company in connection with the exercise of the Option and purchase of Shares. In

             OpenSite Technologies, Inc. 2000 Stock Incentive Plan
                                  Page 7 of 13

<PAGE>   8

the event of such a gift, the Optionee shall promptly notify the Board of such
transfer and deliver to the Board such written documentation as the Board may in
its discretion request, including, without limitation, the written
acknowledgment of the donee that the donee is subject to the provisions of the
Plan, the Stock Incentive Agreement and the Exercise and Shareholder Agreement.

                  (f) SPECIAL PROVISIONS FOR CERTAIN SUBSTITUTE OPTIONS.
Notwithstanding anything to the contrary in this Section, any Option in
substitution for a stock option previously issued by another entity, which
substitution occurs in connection with a transaction to which Code ss.424(a) is
applicable, may provide for an exercise price computed in accordance with Code
ss.424(a) and the regulations thereunder and may contain such other terms and
conditions as the Board may prescribe to cause such substitute Option to contain
as nearly as possible the same terms and conditions (including the applicable
vesting and termination provisions) as those contained in the previously issued
stock option being replaced thereby.

         7.3      TERMS AND CONDITIONS OF STOCK APPRECIATION RIGHTS. A Stock
Appreciation Right may be granted in connection with all or any portion of a
previously or contemporaneously granted Option or not in connection with an
Option. A Stock Appreciation Right shall entitle the Participant to receive upon
exercise or payment the excess of: (I) the Fair Market Value of a specified
number of Shares at the time of exercise, over (II) a specified price which
shall be not less than the Exercise Price for that number of Shares in the case
of a Stock Appreciation Right granted in connection with a previously or
contemporaneously granted Option, or in the case of any other Stock Appreciation
Right not less than one hundred percent (100%) of the Fair Market Value of that
number of Shares at the time the Stock Appreciation Right was granted. A Stock
Appreciation Right granted in connection with an Option may only be exercised to
the extent that the related Option has not been exercised. The exercise of a
Stock Appreciation Right shall result in a pro rata surrender of the related
Option to the extent the Stock Appreciation Right has been exercised.

                  (a) PAYMENT. Upon exercise or payment of a Stock Appreciation
Right, the Company shall pay to the Participant the appreciation in cash or
Shares (at the aggregate Fair Market Value on the date of payment or exercise)
as provided in the Stock Incentive Agreement or, in the absence of such
provision, as the Board may determine.

                  (b) CONDITIONS TO EXERCISE. Each Stock Appreciation Right
granted under the Plan shall be exercisable at such time or times, or upon the
occurrence of such event or events, and in such amounts, as the Board shall
specify in the Stock Incentive Agreement; provided, however, that subsequent to
the grant of a Stock Appreciation Right, the Board, at any time before complete
termination of such Stock Appreciation Right, may accelerate the time or times
at which such Stock Appreciation Right may be exercised in whole or in part.

                  (c) TRANSFERABILITY OF STOCK APPRECIATION RIGHTS. Except as
otherwise provided in a Participant's Stock Incentive Agreement, no Stock
Appreciation Right granted under the Plan may be sold, transferred, pledged,
assigned or otherwise alienated or hypothecated, other than by will or by the
laws of descent and distribution. Further, except as otherwise provided in a
Participant's Stock Incentive Agreement, all Stock Appreciation Rights granted
to a Participant under the Plan shall be exercisable, during the Participant's
lifetime, only by the Participant; provided, however, that in the event the
Participant is incapacitated and unable to exercise his or her Stock
Appreciation Right, such Stock Appreciation Right may be exercised by such
Participant's legal guardian, legal representative, or other representative whom
the Board deems appropriate based on applicable facts and circumstances. The
determination of incapacity of a Participant and the determination of the
appropriate representative of the Participant shall be determined by the Board
in its sole and absolute discretion. Notwithstanding the foregoing, except as
otherwise provided in the Stock Incentive Agreement, (A) a Stock Appreciation
Right which is granted in connection with the grant of a Non-ISO may be
transferred, but only with the Non-ISO, and (B) a Stock Appreciation Right which
is not granted in connection with the grant of a Non-ISO, may be transferred as
a bona fide gift, (i) to his spouse or lineal descendant or lineal ascendant,
(ii) to a trust for the benefit of one or more individuals described in clause
(i), (iii) to a partnership of which the only partners are one or more
individuals described in clause (i), or (iv) to other persons with the prior

             OpenSite Technologies, Inc. 2000 Stock Incentive Plan
                                  Page 8 of 13

<PAGE>   9

approval of the Board in its sole and absolute discretion, in which case the
transferee shall be subject to all provisions of the Plan and the Stock
Incentive Agreement. In the event of such a gift, the Optionee shall promptly
notify the Board of such transfer and deliver to the Board such written
documentation as the Board may in its discretion request, including, without
limitation, the written acknowledgment of the donee that the donee is subject to
the provisions of the Plan and the Stock Incentive Agreement.

         7.4      TERMS AND CONDITIONS OF RESTRICTED STOCK AWARDS. Shares
awarded pursuant to Restricted Stock Awards shall be subject to such
restrictions as determined by the Board for periods determined by the Board.
Unless the applicable Stock Incentive Agreement provides otherwise, holders of
Restricted Stock Awards shall be entitled to vote and receive dividends during
the periods of restriction to the same extent as holders of unrestricted Common
Stock. The Board shall have the power to permit, in its discretion, an
acceleration of the expiration of the applicable restriction period with respect
to any part or all of the Shares awarded to a Participant. The Board may require
a cash payment from the Participant in an amount no greater than the aggregate
Fair Market Value of the Shares awarded determined at the date of grant in
exchange for the grant of a Restricted Stock Award or may grant a Restricted
Stock Award without the requirement of a cash payment. A Restricted Stock Award
may be transferred, except as otherwise provided in the Stock Incentive
Agreement, as a bona fide gift (i) to his spouse or lineal descendant or lineal
ascendant, (ii) to a trust for the benefit of one or more individuals described
in clause (i), (iii) to a partnership of which the only partners are one or more
individuals described in clause (i), or (iv) to other persons with the prior
approval of the Board in its sole and absolute discretion, in which case the
transferee shall be subject to all provisions of the Plan and the Stock
Incentive Agreement. In the event of such a gift, the Optionee shall promptly
notify the Board of such transfer and deliver to the Board such written
documentation as the Board may in its discretion request, including, without
limitation, the written acknowledgment of the donee that the donee is subject to
the provisions of the Plan and the Stock Incentive Agreement.

                                   SECTION 8.
                              SURRENDER OF OPTIONS

         8.1      GENERAL RULE. The Board, acting in its absolute discretion,
may incorporate a provision in a Stock Incentive Agreement to allow an Employee
or Key Person to surrender his or Option in whole or in part in lieu of the
exercise in whole or in part of that Option on any date that:

                  (a) the Fair Market Value of the Shares subject to such Option
exceeds Exercise Price for such Shares, and

                  (b) the Option to purchase such Shares is otherwise
exercisable.

         8.2      PROCEDURE. The surrender of an Option in whole or in part
shall be effected by the delivery of the Stock Incentive Agreement to the Board,
together with a statement signed by the Participant which specifies the number
of Shares ("Surrendered Shares") as to which the Participant surrenders his or
her Option and how he or she desires payment be made for such Surrendered
Shares.

         8.3      PAYMENT. A Participant in exchange for his or her Surrendered
Shares shall receive a payment in cash or in Shares, or in a combination of cash
and Shares, equal in amount on the date such surrender is effected to the excess
of the Fair Market Value of the Surrendered Shares on such date over the
Exercise Price for the Surrendered Shares. The Board, acting in its absolute
discretion, can approve or disapprove a Participant's request for payment in
whole or in part in cash and can make that payment in cash or in such
combination of cash and Shares as the Board deems appropriate. A request for
payment only in Shares shall be approved and made in Shares to the extent
payment can be made in whole shares of Shares and (at the Board's discretion) in
cash in lieu of any fractional Shares.

         8.4      RESTRICTIONS. Any Stock Incentive Agreement which incorporates
a provision to allow a Participant to surrender his or her Option in whole or in
part also shall incorporate such additional restrictions on the exercise or

             OpenSite Technologies, Inc. 2000 Stock Incentive Plan
                                  Page 9 of 13

<PAGE>   10

surrender of such Option as the Board deems necessary to satisfy the conditions
to the exemption under Rule 16b-3 (or any successor exemption) to Section 16(b)
of the Exchange Act.

                                   SECTION 9.
                              SECURITIES REGULATION

         Each Stock Incentive Agreement may provide that, upon the receipt of
Shares as a result of the surrender or exercise of a Stock Incentive, the
Participant shall, if so requested by the Company, hold such Shares for
investment and not with a view of resale or distribution to the public and, if
so requested by the Company, shall deliver to the Company a written statement
satisfactory to the Company to that effect. Each Stock Incentive Agreement may
also provide that, if so requested by the Company, the Participant shall make a
written representation to the Company that he or she will not sell or offer to
sell any of such Shares unless a registration statement shall be in effect with
respect to such Shares under the Securities Act of 1933, as amended ("1933
Act"), and any applicable state securities law or, unless he or she shall have
furnished to the Company an opinion, in form and substance satisfactory to the
Company, of legal counsel acceptable to the Company, that such registration is
not required. Certificates representing the Shares transferred upon the exercise
or surrender of a Stock Incentive granted under this Plan may at the discretion
of the Company bear a legend to the effect that such Shares have not been
registered under the 1933 Act or any applicable state securities law and that
such Shares may not be sold or offered for sale in the absence of an effective
registration statement as to such Shares under the 1933 Act and any applicable
state securities law or an opinion, in form and substance satisfactory to the
Company, of legal counsel acceptable to the Company, that such registration is
not required.

                                   SECTION 10.
                                  LIFE OF PLAN

         No Stock Incentive shall be granted under this Plan on or after the
earlier of:

         (a) the tenth (10th) anniversary of the effective date of this Plan (as
determined under Section 4 of this Plan), in which event this Plan otherwise
thereafter shall continue in effect until all outstanding Stock Incentives have
been surrendered or exercised in full or no longer are exercisable, or

         (b) the date on which all of the Shares reserved under Section 3 of
this Plan have (as a result of the surrender or exercise of Stock Incentives
granted under this Plan) been issued or no longer are available for use under
this Plan, in which event this Plan also shall terminate on such date.

                                   SECTION 11.
                                   ADJUSTMENT

         Notwithstanding anything in Section 13 to the contrary, the number of
Shares reserved under Section 3 of this Plan, the limit on the number of Shares
which may be granted during a calendar year to any individual under Section 3 of
this Plan, the number of Shares subject to Stock Incentives granted under this
Plan, and the Exercise Price of any Options, shall be adjusted by the Board in
an equitable manner to reflect any change in the capitalization of the Company,
including, but not limited to, such changes as stock dividends or stock splits.
Furthermore, the Board shall have the right to adjust (in a manner which
satisfies the requirements of Code ss.424(a)) the number of Shares reserved
under Section 3, and the number of Shares subject to Stock Incentives granted
under this Plan, and the Exercise Price of any Options in the event of any
corporate transaction described in Code ss.424(a) which provides for the
substitution or assumption of such Stock Incentives. If any adjustment under
this Section creates a fractional Share or a right to acquire a fractional
Share, such fractional Share shall be disregarded, and the number of Shares
reserved under this Plan and the number subject to any Stock Incentives granted
under this Plan shall be the next lower number of Shares, rounding all fractions
downward. An adjustment made under this Section by the Board shall be conclusive
and binding on all affected persons and, further, shall not constitute an
increase in the number of Shares reserved under Section 3.

                                   SECTION 12.
                          SALE OR MERGER OF THE COMPANY

         Except to the extent that a Stock Incentive Agreement expressly
provides otherwise, if a Change of Control occurs, and the agreements
effectuating the Change of Control provide for the assumption or substitution of
the Stock Incentives granted under this Plan, each Stock Incentive shall have
its vesting and exercisability accelerated by one year as of the date of the
Change of Control so that, after such acceleration, the recipient of the Stock
Incentive shall be vested in such Stock Incentive as of any date of
determination after such Change of Control in accordance with the terms and
provisions of the Stock Incentive except that it shall be presumed that the date
of determination is actually one year later than the actual date of
determination. Except to the extent that a Stock Incentive Agreement expressly
provides otherwise, to the extent that the recipient of a Stock Incentive
granted under this Plan is employed by the Company immediately prior to a Change
of Control and the employment of such Stock Incentive recipient is terminated in
a Vesting Termination on or within one year following the Change of Control,
then, if the agreements effectuating the Change of Control provide for the
assumption or substitution of the Stock Incentives granted under this Plan, the
vesting and exercisability of the Stock Incentive of such recipient shall be
accelerated by an additional one year as of the date of the Vesting Termination
so that, after such acceleration, the recipient of the Stock Incentive shall be
vested in such Stock Incentive as of any date of determination after the date of
the Vesting Termination in accordance with the terms and provisions of the Stock
Incentive except that it shall be presumed that the date of determination is
actually two years later than the actual date of determination.

         Except to the extent that a Stock Incentive Agreement expressly
provides otherwise, if the Company agrees to a Company Sale or a Company Merger
and such agreement does not provide for the assumption or substitution of the
Stock Incentives granted under this Plan, each Stock Incentive, shall
immediately become fully vested immediately prior to the closing of the
transaction effectuating the Change of Control, and, at the direction and
discretion of the Board, may be canceled unilaterally by the Company in exchange
for (a) whole Shares (or, subject to satisfying the conditions of an exemption
under Rule 16b-3 or any successor exemption to Section 16(b) of the Exchange
Act, for the whole Shares and cash in lieu of any fractional Share) which each
Participant otherwise would receive if he or she had the right to surrender or
exercise his or her outstanding Stock Incentive in full and he or she exercised
that right exclusively for Shares on a date fixed by the Board which comes
before such sale or other corporate transaction, or (b) cash or other property
equivalent in value, as determined by the Board in its sole discretion, to the
Shares described in clause (a) of this sentence.

                                   SECTION 13.
                            AMENDMENT OR TERMINATION

         This Plan may be amended by the Board from time to time to the extent
that the Board deems necessary or appropriate; provided, however, no such
amendment shall be made absent the approval of the shareholders of the Company:
(a) to increase the number of Shares reserved under Section 3, except as set
forth in Section 11, (b) to extend the maximum life of the Plan under Section 10
or the maximum exercise period under Section 7, (c) to decrease the minimum
Exercise Price under Section 7, or (d) to change the designation of Employees or
Key Persons eligible for Stock Incentives under Section 6. The Board also may
suspend the granting of Stock Incentives under this Plan at any time and may
terminate this Plan at any time. The Company shall not have the right to modify,
amend or cancel any Stock Incentive after it has been granted before such
unless: (I) the Participant consents in writing to such modification, amendment
or cancellation, or (II) there is a dissolution or liquidation of the Company or
a transaction described in Section 11 or Section 12, or (III) the Company would
otherwise have the right to make such modification, amendment or cancellation by
applicable law.

                                   SECTION 14.
                                  MISCELLANEOUS

         14.1     SHAREHOLDER RIGHTS. No Participant shall have any rights as a
shareholder of the Company as a result of the grant of a Stock Incentive to him
or to her under this Plan or his or her exercise or surrender of such Stock
Incentive pending the actual delivery of Shares subject to such Stock Incentive
to such Participant.

         14.2     NO GUARANTEE OF CONTINUED RELATIONSHIP. The grant of a Stock
Incentive to a Participant under this Plan shall not constitute a contract of
employment, shall not confer on any Participant any right to continued
employment, and shall not confer on a Participant any rights upon his or her
termination of employment or relationship with the Company in addition to those
rights, if any, expressly set forth in the Stock Incentive Agreement which
evidences his or her Stock Incentive. Nothing contained in the Plan, or any
modification thereof, or any Stock Incentive granted under this Plan shall be
construed to give any Participant any rights to continued employment.

         14.3     WITHHOLDING. The Company shall have the power and the right to
deduct or withhold, or require a Participant to remit to the Company as a
condition precedent for the fulfillment of any Stock Incentive, an amount
sufficient to satisfy Federal, state and local taxes, domestic or foreign,
required by law or regulation to be withheld with respect to any taxable event
arising as a result of this Plan. Whenever Shares are to be issued or cash paid
to a Participant upon exercise of an Option, the Company shall have the right to
require the Participant to remit to the Company, as a condition of exercise of
the Option, an amount sufficient to satisfy federal, state and local withholding
tax requirements at the time of exercise. However, notwithstanding the
foregoing, to the extent that a Participant is an Insider, satisfaction of
withholding requirements by having the Company withhold Shares may only be made
to the extent that such withholding of Shares (1) has met the requirements of an
exemption under Rule 16b-3 promulgated under the Exchange Act, or (2) is a
subsequent transaction the terms of which were provided for in a transaction
initially meeting the requirements of an exemption under Rule 16b-3 promulgated
under the Exchange Act. Unless the Stock Incentive Agreement provides otherwise,
the withholding of shares to satisfy federal, state and local withholding tax
requirements shall be a subsequent transaction approved by the original grant of
a Stock Incentive. Notwithstanding the foregoing, in no event shall payment of
withholding taxes be made by a retention of Shares by the Company unless the
Company retains only Shares with a Fair Market Value equal to the minimum amount
of taxes required to be withheld.

         14.4     NOTIFICATION OF DISQUALIFYING DISPOSITIONS OF ISO OPTIONS. If
a Participant sells or otherwise disposes of any of the Shares acquired pursuant
to an Option which is an ISO on or before the later of (1) the date two (2)
years after the date of grant of such Option, or (2) the date one (1) year after
the exercise of such Option, then the Participant shall immediately notify the
Company in writing of such sale or disposition and shall cooperate with the
Company in providing sufficient information to the Company for the Company to
properly report such sale or disposition to the Internal Revenue Service. The
Participant acknowledges and agrees that he may be subject to income tax
withholding by the Company on the compensation income recognized by Participant
from any such early disposition by either (or both) his payment to the Company
in cash or his payment out of the current wages or earnings otherwise payable to
him by the Company, and agrees that he shall include the compensation from such
early disposition in his gross income for federal tax purposes. Participant also
acknowledges that the Company may condition the exercise of any Option which is
an ISO on the Participant's express written agreement with these provisions of
this Plan.

         14.5     TRANSFER. The transfer of an Employee between or among the
Company, a Subsidiary or a Parent shall not be treated as a termination of his
or her employment under this Plan.

         14.5     CONSTRUCTION. This Plan shall be construed under the laws of
the State of Delaware.

         14.6     SEVERABILITY. If any portion of this Plan is held invalid or
inoperative, the other portions of this Plan shall be deemed valid and operative
and, so far as is reasonable and possible, effect shall be given to the intent
manifested by the portion held invalid or inoperative.
