         --------------------------

         (a) Subject to adjustment under subsection (b) below, Awards may be
made under the Plan for up to 2,525,500 shares of Common Stock. If any Award in
respect of shares of Common Stock expires or is terminated unexercised or is
forfeited for any reason or settled in a manner that results in fewer shares
outstanding than were initially awarded, the shares subject to such Award or so
surrendered, as the case may be, to the extent of such expiration, termination,
forfeiture or decrease, shall again be available for award under the Plan,
subject, however, in the case of Incentive Stock Options, to any limitation
required under the Code and provided that shares made available pursuant to this
sentence shall be available for Awards to Reporting Persons only to the extent
consistent with Rule 16b-3. Shares issued under the Plan may consist in whole or

that any stock dividend, extraordinary cash dividend, recapitalization,
reorganization, merger, consolidation, split-up, spin-off, combination or other
similar transaction affects the Common Stock such that an adjustment is required
in order to preserve the benefits or potential benefits intended to be made
available under the Plan, then the Board, subject, in the case of Incentive
Stock Options, to any limitation required under the Code, shall equitably adjust
any or all of (i) the number and kind of shares in respect of which Awards may
be made under the Plan, (ii) the number and kind of shares subject to
outstanding Awards, and (iii) the award, exercise or conversion price with
respect to any of the foregoing, and if considered appropriate, the Board may
make provision for a cash payment with respect to an outstanding Award, provided
that the number of shares subject to any Award shall always be a whole number.

         (c) The Board may grant Awards under the Plan in substitution for stock
and stock based awards held by employees of another corporation who concurrently
become employees of the Company as a result of a merger or consolidation of the
employing corporation with the Company (or a subsidiary of the Company) or the
acquisition by the Company (or a subsidiary of the Company) of property or stock
of the employing corporation. The substitute Awards shall be granted on such
terms and conditions as the Board considers appropriate in the circumstances.

6.       Stock Options
         -------------

         (a) General

             (i)  Subject to the provisions of the Plan, the Board may award

such Option. The terms and conditions of Incentive Stock Options shall be
subject to and comply with Section 422 of the Code, or any successor provision,
and any regulations thereunder.

             (ii) The Board shall establish the exercise price at the time each
option is awarded. In the case of Incentive Stock options, such price shall not

of award.

<PAGE>

                  (iii) Each Option shall be exercisable at such times and
subject to such terms and conditions as the Board may specify in the applicable
Award or thereafter. The Board may impose such conditions with respect to the
exercise of options, including conditions relating to applicable federal or
state securities laws, as it considers necessary or advisable.

                  (iv)  Options granted under the Plan may provide for the
payment of the exercise price by delivery of cash or check in an amount equal to
the exercise price of such options or, to the extent permitted by the Board at
or after the award of the Option, by (A) delivery of shares of Common Stock
owned by the optionee for at least six months (or such shorter period as is
approved by the Board), valued at their Fair Market Value, (B) delivery of a

the Company sufficient funds to pay the exercise price or delivery of

a check sufficient to pay the exercise price, (D) payment of such other lawful
consideration as the Board may determine, or (E) any combination of the
foregoing.

                  (v)   The Board may provide for the automatic award of an

price of an Option for up to the number of shares so delivered.

all or any part of an Option may be exercised:

                  -----------------------

                  Options granted under the Plan which are intended to be

be granted under the Plan is, at the time of the grant of such option, the owner
of stock possessing more than 10% of the total combined voting power of all
classes of stock of the Company (after taking into account the attribution of
stock ownership rule of Section 424(b) and of the Code), then the following
special provisions shall be applicable to the Incentive Stock Option granted to
such individual:

                           (x)  The purchase price per share of the Common Stock
         subject to such Incentive Stock Option shall not be less than 110% of
         the Fair Market Value of one share of Common Stock at the time of
         grant; and

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

                  (iii) For so long as the Code shall so provide, options
granted to any employee under the Plan (and any other incentive stock option
plans of the Company) which are intended

<PAGE>

to constitute Incentive Stock Options shall not constitute Incentive Stock
Options to the extent that such options, in the aggregate, become exercisable
for the first time in any one calendar year for shares of Common Stock with an
aggregate Fair Market Value (determined as of the respective date or dates of
grant) of more than $100,000.

                  (iv)  No Incentive Stock Option may be exercised unless, at
the time of such exercise, the Participant is, and has been continuously since
the date of grant of his or her option, employed by the Company, except that:

                           (x) an Incentive Stock Option may be exercised within
         the period of three months after the date the Participant ceases to be
         an employee of the Company (or within such lesser period as may be
         specified in the applicable option agreement), provided, that the
                                                        --------
         agreement with respect to such option may designate a longer exercise
         period and that the exercise after such three-month period shall be
         treated as the exercise of a Nonstatutory Stock option under the Plan;

                           (y) if the Participant dies while in the employ of
         the Company, or within three months after the Participant ceases to be
         such an employee, the Incentive Stock Option may be exercised by the
         Participant's Designated Beneficiary within the period of one year
         after the date of death (or within such lesser period as may be
         specified in the applicable Option agreement); and

                           (z) if the Participant becomes disabled (within the
         meaning of Section 22(e)(3) of the Code or any successor provision
         thereto) while in the employ of the Company, the Incentive Stock Option
         may be exercised within the period of one year after the date of
         disability (or within such lesser period as may be specified in the
         applicable option agreement).

For all purposes of the Plan and any option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the

foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.

                  (v)   Incentive Stock Options and all options granted to
Reporting Persons, shall not be assignable or transferable by the person to whom
they are granted, either voluntarily or by operation of law, except by will or

recipients to acquire shares of Common Stock, subject to the right of the
Company to repurchase all or part of such shares at their purchase price (or
to require forfeiture of such shares if purchased at no cost) from the recipient
in the event that conditions specified by the Board in the applicable Award are
not satisfied prior to the end of the applicable Restricted Period or Restricted
Periods established by the Board for such Award. Conditions for repurchase (or

pre-established performance or other goals and objectives.

<PAGE>

         (b) Shares of Restricted Stock may not be sold, assigned, transferred,
pledged or otherwise encumbered, except as permitted by the Board, during the

restrictions under the Plan ("Unrestricted Stock").

         (d) The purchase price for each share of Restricted Stock and

thereof and containing such other terms and conditions not inconsistent with the
provisions of the Plan as the Board considers necessary or advisable. Such
instruments may be in the form of agreements to be executed by both the Company
and the Participant, or certificates, letters or similar documents, acceptance
of which will evidence agreement to the terms thereof and of this Plan.

<PAGE>

         (d) Board Discretion. Except as otherwise provided by the Plan, each
             ----------------
type of Award may be made alone, in addition to or in relation to any other type
of Award. The terms of each type of Award need not be identical, and the Board
need not treat Participants uniformly. Except as otherwise provided by the Plan
or a particular Award, any determination with respect to an Award may be made by
the Board at the time of award or at any time thereafter.

         (e) Termination of Status. Subject to the provisions of Section

Company, the Board of Directors of the Company, or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,

upon written notice to Participants, provide that all unexercised options will
terminate immediately prior to the consummation of such transaction unless
exercised by the Participant within a specified period following the date of
such notice, (iii) in the event of an Acquisition under the terms of which

of any kind otherwise due to the Participant.

             -----------------
foreign nationals or employed outside the United States on such terms and
conditions different from those specified in the Plan as the Board considers
necessary or advisable to achieve the purposes of the Plan or comply with
applicable laws.

<PAGE>

         (i) Amendment of Award. The Board may amend, modify or terminate any
             ------------------
outstanding Award, including substituting therefor another Award of the same or
a different type, changing the date of exercise or realization and converting an
Incentive Stock Option to a Nonstatutory Stock Option, provided that the
Participant's consent to such action shall be required unless the Board
determines that the action, taking into account any related action, would not
materially and adversely affect the Participant.

         (j) Cancellation and New Grant of Options. The Board of Directors shall
             -------------------------------------
have the authority to effect, at any time and from time to time, with the
consent of the affected optionees, (i) the cancellation of any or all

opinion of the Company's counsel, all applicable federal and state laws and
regulations have been complied with, (iii) if the outstanding Common Stock is

notice of issuance, and (iv) until all other legal matters in connection with
the issuance and delivery of such shares have been approved by the Company's
counsel. If the sale of Common Stock has not been registered under the
Securities Act of 1933, as amended, the Company may require, as a condition to
exercise of the Award, such representations or agreements as the Company may
consider appropriate to avoid violation of such Act and may require that the
certificates evidencing such Common Stock bear an appropriate legend restricting
transfer.

9.       Miscellaneous
         -------------

         (a) No Right To Employment or Other Status. No person shall have any
             --------------------------------------
claim or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or service
for the Company. The Company expressly reserves the right at any time to dismiss
a Participant free from any liability or claim under the Plan, except as
expressly provided in the applicable Award.

         (b) No Rights As Stockholder. Subject to the provisions of the
             ------------------------
applicable Award, no Participant or Designated Beneficiary shall have any rights
as a stockholder with respect to any shares of Common Stock to be distributed
under the Plan until he or she becomes the record holder thereof.

         (c) Exclusion from Benefit Computations. No amounts payable upon
             -----------------------------------
exercise of Awards granted under the Plan shall be considered salary, wages or
compensation to Participants for purposes of determining the amount or nature of
benefits that Participants are entitled to under any insurance, retirement or
other benefit plans or programs of the Company.

<PAGE>

         (d) Effective Date and Term. The Plan became effective on June 7, 1994,
             -----------------------
the date it was adopted by the Board of Directors, but no Incentive Stock Option
granted under the Plan shall become exercisable unless and until the Plan shall
have been approved by the Company's stockholders. If such stockholder approval
is not obtained within twelve months after the date of the Board's adoption of
the Plan, no options previously granted under the Plan shall be deemed to be
Incentive Stock Options and no Incentive Stock Options shall be granted
thereafter. No Award may be made under the Plan after June 6, 2004, but Awards
previously granted may extend beyond that date.

         (e) Amendment of Plan. The Board may amend, suspend or terminate the
             -----------------
Plan or any portion thereof at any time, provided that no amendment shall be
made without stockholder approval if such approval is necessary to comply with
any applicable tax or regulatory requirement, including any requirements for
compliance with Rule 16b-3. Amendments requiring stockholder approval shall
become effective when adopted by the Board of Directors, but no Incentive Stock
Option granted after the date of such amendment shall become exercisable (to the
extent that such amendment to the Plan was required to enable the Company to
grant such Incentive Stock Option to a particular Participant) unless and until
such amendment shall have been approved by the Company's stockholders. If such
stockholder approval is not obtained within twelve months of the Board's
adoption of such amendment, any Incentive Stock options granted on or after the
date of such amendment shall terminate to the extent that such amendment to the
Plan was required to enable the Company to grant such option to a particular
Participant.

         (f) Governing Law.  The provisions of the Plan shall be governed by and
             -------------
interpreted in accordance with the laws of the Commonwealth of Massachusetts.

                                  divine, inc.

              INCENTIVE STOCK OPTION AGREEMENT FOR OPTIONS GRANTED
              UNDER THE OPEN MARKET, INC. 1994 STOCK INCENTIVE PLAN

Explanatory Note
----------------

On October 19, 2001, divine, inc. acquired Open Market, Inc. in a
stock-for-stock merger. As a result, any outstanding options to purchase shares
of Open Market common stock were converted into options to purchase shares of
class A common stock, par value $0.001 per share, of divine. Each Open Market
option now represents an option to purchase a number of divine shares equal to
the number of Open Market shares subject to such Open Market option multiplied
                                                                    ----------
by 0.8326, the exchange ratio in the merger. The exercise price for each
converted divine option equals the exercise price of the Open Market option
divided by 0.8326.
----------

Other than as set forth in the paragraph above, the rights and obligations of
each holder of Open Market options granted pursuant to this agreement remain in
full force and effect.

     1.   Grant of Option. Open Market, Inc., a Delaware corporation, hereby
          grants to __________ (the "Optionee"), an option, pursuant to the Open
          Market, Inc. 1994 Stock Incentive Plan (the "Plan"), to purchase an
          aggregate of ___ shares of class A common stock, par value $.001 per
          share, of divine, inc. (the "Company") ("Common Stock") at a price of
          $____ per share, purchasable as set forth in and subject to the terms
          and conditions of this option and the Plan. Except where the context
          otherwise requires, the term "Company" shall include the parent and
          all present and future subsidiaries of the Company as defined in
          Sections 424(e) and 424(f) of the Internal Revenue Code of 1986, as
          amended or replaced from time to time (the "Code").

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

     3.   Exercise of Option and Provisions for Termination.

          (a)  Vesting Schedule. Except as otherwise provided in this Agreement,
               this option may be exercised during the period commencing
               [exdate] and ending on the tenth anniversary of the Grant Date
               set forth on the signature page hereof (the "Expiration Date") in
               installments as follows: (1) [quarter_] shares as of the one
               year anniversary date of the Grant Date (the "Initial Vesting
               Date") and (2) for each subsequent three-month period following
               the Initial Vesting Date, as to no more than the number of shares
               equal to the product of (i) [remainder] multiplied by (ii) the
               number of consecutive three-month periods that the Optionee is
               employed by the Company after [exdate]. The right of exercise
               shall be cumulative so that if the option is not exercised to the
               maximum extent permissible during any exercise period, it shall
               be exercisable, in whole or in part, with respect to all shares
               not so purchased at any time prior to the Expiration Date or the
               earlier termination of this option. This option may not be
               exercised at any time on or after the Expiration Date.

          (b)  Exercise Procedure. Subject to the conditions set forth in this
               Agreement, this option shall be exercised by the Optionee's
               delivery of a properly completed irrevocable notice of option
               exercise, as outlined in the Company's Policy Memorandum on stock
               option exercises, to the Stock Administrator of the Company, and
               accompanied by payment in full in accordance with Section 4
               (unless a cashless exercise is designated on the option exercise
               form). Such exercise shall be effective upon receipt by the Stock
               Administrator of the Company of such notice

<PAGE>

               together with the required payment. The Optionee may purchase
               less than the number of shares covered hereby, provided that no
               partial exercise of this option may be for any fractional share
               or for fewer than 100 whole shares.

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

          d)   Exercise Period Upon Termination of Employment. If the Optionee
               ceases to be employed by the Company for any reason, then, except
               as provided in paragraphs (e) and (f) below, the right to
               exercise this option shall terminate three months after such
               cessation (but in no event after the Expiration Date), provided
               that this option shall be exercisable only to the extent that the
               Optionee was entitled to exercise this option on the date of such
               cessation. The Company's obligation to deliver shares upon the
               exercise of this option shall be subject to the satisfaction of
               all applicable federal, state and local income and employment tax
               withholding requirements, arising by reason of this option being
               treated under applicable law as a non-statutory option or
               otherwise. Notwithstanding the foregoing, if the Optionee, prior
               to the Expiration Date, materially violates the non-competition
               or confidentiality provisions of any employment contract,
               confidentiality and nondisclosure agreement or other agreement
               between the Optionee and the Company, the right to exercise this
               option shall terminate immediately upon written notice to the
               Optionee from the Company describing such violation.

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

          (f)  Discharge for Cause. If the Optionee, prior to the Expiration
               Date, is discharged by the Company for "cause" (as defined
               below), the right to exercise this option shall terminate
               immediately upon such cessation of employment. As used herein,
               the term "Cause" shall mean any of the following:

               (i)  a good faith finding by the Company (which finding shall be
                    conclusive) of failure of the Optionee to perform his or her
                    assigned duties for the Company, dishonesty, gross
                    negligence or misconduct, (including without limitation,
                    breach by the Optionee of any provision of any employment,
                    nondisclosure, non-competition or other similar agreement
                    between the Optionee and the Company); further, the Optionee
                    shall be considered to have been discharged "for cause" if
                    the Company determines, within 30 days after the Optionee's
                    resignation or termination, that discharge for cause was
                    warranted.

<PAGE>

               (ii) the Optionee's conviction of a felony;

              (iii) the Optionee's conviction of any lesser crime or offense
                    committed in connection with the performance of his duties
                    hereunder and involving moral turpitude; or

               (iv) the Optionee is habitually intoxicated by alcohol or under
                    the influence of drugs and is therefore unable to perform
                    his employment obligations.

     4.  Payment of Purchase Price.

          (a)  Method of Payment. Payment of the purchase price for shares
               purchased upon exercise ofthis option shall be made (i) by
               delivery to the Company of cash or a check to the order of the
               Company in an amount equal to the purchase price of such shares,
               (ii) subject to the consent of the Company, by delivery to the
               Company of shares of Common Stock of theCompany then owned by the
               Optionee having a fair market value equal in amount to the
               purchase price of such shares, (iii) by any other means which the
               Board of Directors determines are consistent with the purpose of
               the Plan and with applicable laws and regulations (including,
               without limitation, the provisions of Rule 16b-3 under the
               Securities Exchange Act of 1934 and Regulation T promulgated by
               the Federal Reserve Board), or (iv) by any combination of such
               methods of payment.

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

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

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

     5.  Delivery of Shares; Compliance With Securities Laws, Etc.

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

          (b)  Listing, Qualification, Etc. This option shall be subject to the
               requirement that if, at any time, counsel to the Company shall
               determine that the listing, registration or qualification of the
               shares subject hereto upon any securities exchange or under any
               state or federal law, or the consent or approval of any
               governmental or regulatory body, or that the disclosure of
               non-public information or the satisfaction of any other condition
               is necessary as a conditionof, or in connection with, the
               issuance or purchase of shares hereunder, this option may not be
               exercised, in whole or in part, unless such listing,
               registration, qualification, consent or

<PAGE>
               approval, disclosure or satisfaction of such other condition
               shall have been effected or obtained on terms acceptable to the
               Board of Directors. Nothing herein shall be deemed to require the
               Company to apply for, effect or obtain such listing,
               registration, qualification, or disclosure, or to satisfy such
               other condition.

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

     7.   No Special Employment Rights. Nothing contained in the Plan or this
          option shall be construed or deemed by any person under any
          circumstances to bind the Company to continue the employment of the
          Optionee for the period within which this option may be exercised.

     8.   Rights as a Shareholder. The Optionee shall have no rights as a
          shareholder with respect to any shares which may be purchased by
          exercise of this option (including, without limitation, any rights to
          receive dividends or non-cash distributions with respect to such
          shares) unless and until a certificate representing such shares is
          duly issued and delivered to the Optionee. No adjustment shall be made
          for dividends or other rights for which the record date is prior to
          the date such stock certificate is issued.

     9.   Adjustment Provisions.

          (a)  General. If, through, or as a result of, any merger,
               consolidation, sale of all or substantially all of the assets of
               the Company, reorganization, recapitalization, reclassification,
               stock dividend, stock split, reverse stock split or other similar
               transaction, (i) the outstanding shares of Common Stock are
               increased or decreased or are exchanged for a different number or
               kind of shares or other securities of the Company, or (ii)
               additional shares or new or different shares or other securities
               of the Company or other non-cash assets are distributed with
               respect to such shares of Common Stock or other securities, the
               Optionee shall, with respect to this option or any unexercised
               portion hereof, be entitled to the rights and benefits, and be
               subject to the limitations, set forth in Section 5(b) of the
               Plan.

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

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

     10.  Mergers, Consolidation, Distributions, Liquidations Etc. In the event
          of a consolidation or merger or sale of all or substantially all of
          the assets of the Company in which outstanding shares of Common Stock
          are exchanged for securities, cash or other property of any other
          corporation or business entity, or in the event of a liquidation of
          the Company, prior to the Expiration Date or termination of this
          option, the Optionee shall, with respect to this option or any
          unexercised portion hereof, be entitled to the rights and benefits,
          and be subject to the limitations, set forth in Section 8(f) of the
          Plan.

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

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

     13.  Investment Representations; Legends.

          (a)  Representations. The Optionee represents, warrants and covenants
               that:

               (i)  Any shares purchased upon exercise of this option shall be
                    acquired for the Optionee's account for investment only and
                    not with a view to, or for sale in connection with, any
                    distribution of the shares in violation of the Securities
                    Act or any rule or regulation under the Securities Act.

               (ii) The Optionee has had such opportunity as he or she has
                    deemed adequate to obtain from representatives of the
                    Company such information as is necessary to permit the
                    Optionee to evaluate the merits and risks of his or her
                    investment in the Company.

              (iii) The Optionee is able to bear the economic risk of holding
                    shares acquired pursuant to the exercise of this option for
                    an indefinite period.

               (iv) The Optionee understands that the shares acquired pursuant
                    to the exercise of this option are currently registered
                    under the Securities Act. However, if at some later point in
                    time the shares acquired pursuant to the exercise of this
                    option are not registered under the Securities Act, (A) the
                    shares acquired pursuant to the exercise of this option will
                    be "restricted securities" within the meaning of Rule 144
                    under the Securities Act; (B) such shares cannot be sold,
                    transferred or otherwise disposed of unless they are
                    subsequently registered under the Securities Act or an
                    exemption from registration is then available; and (C) in
                    any event, an exemption from registration under Rule 144 or
                    otherwise under the Securities Act may not be available for
                    at least two years and even then will not be available
                    unless a public market then exists for the Common Stock,
                    adequate information concerning the Company is then
                    available to the public and other terms and conditions of
                    Rule 144 are complied with.

               By making payment upon exercise of this option, the Optionee
               shall be deemed to have reaffirmed, as of the date of such
               payment, the representations made in this Section 13.

          (b)  Legends on Stock Certificates. All stock certificates
               representing shares of Common Stock issued to the Optionee upon
               exercise of this option shall have affixed thereto any legend
               required by applicable state law:

     14.  Miscellaneous.

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

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

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