to participate in this Plan only as provided in Section 3(d).  Subject to any
limits or restrictions imposed by the Board from time to time (which limits or

Committee may rely; (viii) establish the maximum aggregate number of Stock
Appreciation Rights which may be granted under this plan from time to time; and

unless otherwise determined by the Board.

                                       2
<PAGE>

     (b) No member of the Board or the Committee will be liable for any action
or determination made in good faith with respect to this Plan or any Stock Right
granted under it.  Each member of the Committee will be indemnified and held
harmless by the Company against any cost or expense (including counsel fees)
reasonably incurred by such member or liability (including any sum paid in
settlement of a claim with the approval of the Company) arising out of any act
or omission to act in connection with this Plan unless arising out of such
member's own fraud or bad faith.  Such indemnification will be in addition to
any rights of indemnification the members of the Committee may have as directors
or otherwise under the by-laws of the Company, or any agreement, vote of
stockholders or disinterested directors, or otherwise.

     (c) The Committee may select one of its members as its chair, and will hold
meetings at its discretion.  A majority of the Committee will constitute a
quorum.  The acts of a majority of the members of the Committee present at any
meeting at which a quorum is present or acts approved in writing by a majority
of the members of the Committee will be the valid acts of the Committee.  From
time to time the Board may increase the size of the Committee and appoint
additional members, remove members (with or without cause) and appoint
replacement members, fill vacancies however caused, and remove all members of
the Committee and thereafter directly administer this Plan.

     (d) Stock Rights may be granted to members of the Committee pursuant to
this Plan if such grants have been approved by a majority vote of the
disinterested members of the Board.

     4.  Stock.   The aggregate number of shares of Common Stock which may be
         -----
issued under this Plan is Three Million Five Hundred Thousand (3,500,000),
subject to adjustment as provided in Section 11.  The Committee may grant
Options and Stock Appreciation Rights and may authorize Purchases and Awards
with respect to such shares in such combinations and for such amount of shares
as it determines are appropriate, provided that the aggregate number of shares
issuable upon exercise of such Options, Purchases and Stock Appreciation Rights
and upon grant of such Awards does not exceed such number, as adjusted.  Stock
subject to Stock Rights may be authorized but unissued shares of Common Stock or
Common Stock held in the treasury of the Company.  If any Stock Right expires or
terminates for any reason without having been exercised in full or ceases for
any reason to be exercisable in whole or in part, or if the Company reacquires
any unvested shares issued pursuant to Stock Rights, then the unexercised shares
subject to such Stock Right and any unvested shares so reacquired by the Company
will again be available for grants of Stock Rights.

     5.  Granting of Stock Rights; Eligibility.   The Committee is authorized to
         -------------------------------------
grant Stock Rights to such employees, consultants, officers and directors
(whether or not an employee) of the Company or its Affiliates at such time or
times as it may determine, all in its sole discretion.  Each Stock Right will be
evidenced by a written agreement in such form as the Committee may from time to
time approve.  Each agreement for an ISO will require the Optionee to notify the
Company in writing immediately after the Optionee makes a Disqualifying
Disposition of any Common Stock acquired pursuant to the exercise of the ISO.

                                       3
<PAGE>

The Committee may from time to time confer authority on one or more of its own
members and/or one or more officers of the Company to execute and deliver such
agreements.  The officers of the Company are authorized and directed to take any
and all action necessary or advisable from time to time to carry out the terms
of each agreement entered into pursuant to this Plan.

     6.  Option Price and Term; ISO Limitations.
         --------------------------------------

     (a) The exercise price for each ISO share will be at least equal to the
fair market value per share on the Date of Grant.  However, if the Optionee owns
more than ten percent of the total combined voting power of all classes of stock
of the Company or an Affiliate, the exercise price must be at least one hundred
ten percent (110%) of the fair market value per share on the Date of Grant,
determined without regard to any restriction other than a restriction which, by
its terms, will never lapse. The Committee may determine the exercise price of
Non-Qualified Options in its sole discretion.

     (b) Each Option will expire on the date specified by the Committee.
However, any ISOs granted to an employee owning more than ten percent of the
total combined voting power of all classes of stock of the Company or an
Affiliate must expire not more than five years from the Date of Grant and all
other ISOs must expire not more than ten years from the Date of Grant.

     (c) ISOs may be granted only to employees of the Company or an Affiliate.
Non-Qualified Options may be granted to any director or officer (whether or not
an employee), employee or consultant of the Company or an Affiliate.

     (d) To the extent that the aggregate fair market value (determined as of
the Date of Grant) of Common Stock with respect to which ISOs (determined
without regard to this paragraph) are exercisable for the first time by any
Optionee during any calendar year under all plans of the Company and its
Affiliates exceeds $100,000, such ISOs will be treated as Non-Qualified Options.

     (e) The fair market value of a share of Common Stock on the Date of Grant
will be the closing price on such date on the securities market where the Common
Stock of the Company is traded, or if there were no sales on the Date of Grant,
on the next preceding date within a reasonable period (as determined in the sole
discretion of the Committee) on which there were sales.  In the event that there
were no sales in such a market within a reasonable period or if the Common Stock
is not publicly traded on the Date of Grant, the fair market value will be as
determined in good faith by the Committee in its sole discretion after taking
into consideration all factors which it deems appropriate including, without
limitation, recent sale and offer prices of the Common Stock in private
transactions negotiated at arm's length.

     7.  Stock Appreciation Rights.
         -------------------------

     (a) The Committee will have the authority to grant Stock Appreciation
Rights with or apart from the grant of Options under this Plan.  Stock
Appreciation Rights may be paid in cash or shares of Common Stock, or any
combination of each, as the Committee may determine and will be subject to such
terms and conditions as the Committee may specify.

     (b) Each Stock Appreciation Right granted with a specified Option will
entitle the Grantee to receive the following amount if and when the specified
Option becomes exercisable: unless the Committee determines otherwise, the
amount to be received by the Grantee will equal the difference between (i) the
fair market value of a share of Common Stock on the date of exercise of the
Right and (ii) the exercise price of a share under the specified Option.

     (c) Each Stock Appreciation Right granted without reference to a specified
Option will entitle the Grantee to receive, unless the Committee determines
otherwise, the difference between (i) the fair market value of a share of Common
Stock on the date of exercise of the Right and (ii) the fair market value of a
share of Common Stock on the date the Right was granted.

     (d) Notwithstanding the foregoing, for those Grantees subject to Section
16(b) of the Act, any transaction involving the exercise of a Stock Appreciation
Right will be structured to satisfy the requirements of Rule 16b-3.

     8.  Means of Exercising Stock Rights.  To exercise a Stock Right (or any
         --------------------------------
part thereof), a Grantee must give written notice to the Company at its
principal office address identifying the Stock Right being exercised, specifying
the portion of the Stock Right being exercised (including the number of shares,
if any, for which Stock Right is being exercised), and accompanied by full
payment of the purchase price (if any) either (a) in United States cash or cash
equivalent or (b) at the discretion of the Committee, (i) in shares of Common
Stock having a fair market value on the date of exercise equal to the exercise
price of the Stock Right, (ii) by delivery of the Grantee's promissory note to
the Company in an amount equal to the exercise price of the Stock Right, (iii)
by written notice to the Company to withhold from those shares of Common Stock
that would otherwise be obtained on the exercise of such Stock Right the number
of shares having a fair market value on the date of exercise equal to the
exercise price, (iv) in cash by a broker-dealer acceptable to the Company to
whom the Grantee has submitted an irrevocable notice of exercise, or (v) by any
combination of the foregoing.  The holder of a Stock Right will not have the
rights of a shareholder with respect to any shares covered by the Stock Right
until the date of issuance of a stock certificate for such shares.  Except as
otherwise determined by the Committee, no adjustment will be made for dividends
or similar rights for which the record date is before the date such stock
certificate is issued.

     9.  Termination of Employment; Limitations on Exercise.  Upon termination
         --------------------------------------------------
of a Grantee's employment with or service to the Company, (a) no further vesting
of the Grantee's Options and Stock Appreciation Rights will occur subsequent to
the date of termination, (b) the

                                       5
<PAGE>

Grantee's ISOs will terminate on the earlier of (i) their specified expiration
dates, (ii) in the case of a termination due to the Grantee's death or
Disability, one (1) year after the date of termination, or (iii) in the case of
termination for any other reason, on the date three months after the date of
termination, (c) the Grantee's Non-Qualified Stock Options and Stock
Appreciation Rights will terminate one (1) year after the date of termination,
or on their specified expiration dates, if earlier, and (d) all other types of
Stock Rights will immediately terminate and cease to be exercisable except to
the extent otherwise provided by the Committee. Nothing in this Plan will be
deemed to give any Grantee the right to continued employment with the Company.

     10.  Assignability.  No Stock Right will be assignable or transferable by a
          -------------
Grantee, either voluntarily or by operation of law, except by will or by the
laws of descent and distribution.  During the lifetime of the Grantee no Stock
Right will be exercisable by or payable to anyone other than the Grantee or his
legal representative.

     11.  Adjustments.  Notwithstanding any other provision of this Plan, the
          -----------
Committee may at any time make or provide for such adjustments to this Plan, to
the number and class of shares available under this Plan or to any outstanding
Stock Rights, as it deems appropriate to prevent dilution or enlargement of
rights, including adjustments in the event of distributions to holders of Common
Stock of other than a normal cash dividend, and changes in the outstanding
Common Stock by reason of stock dividends, split-ups, recapitalizations,
mergers, consolidations, combinations or exchanges of shares, separations,
reorganizations, liquidations and the like.  In the event of any general offer
to holders of Common Stock relating to the acquisition of their shares, the
Committee may make such adjustment as it deems equitable in respect of
outstanding Stock Rights including, in the Committee's discretion, revision of
outstanding Stock Rights so that they may be exercisable for the consideration
payable in the acquisition transaction.  Any such determination by the Committee
will be conclusive.

     12.  Amendment of Plan.  The Board may terminate or amend this Plan in any
          -----------------
manner allowed by law at any time, provided that no amendment to this Plan will
be effective without approval of the stockholders of the Company if stockholder
approval of the amendment is then required under Rule 16b-3 of the Act, Sections
162(m) or 422 of the Code, the rules of any stock exchange or other applicable
federal or state law.  In no event may action of the Board or stockholders
adversely alter or impair the rights of a Grantee, without the Grantee's
consent, under any Stock Right previously granted to such Grantee.  Stock Rights
may be granted prior to the date of stockholder approval of this Plan.

     13.  Application of Funds.  All proceeds received by the Company with
          --------------------
respect to Stock Rights will be used for general corporate purposes.

     14.  Governmental Regulation.  The Company's obligation to sell and deliver
          -----------------------
shares of Common Stock under this Plan is subject to the approval of any
governmental authority required in connection with the authorization, issuance
or sale of such shares and the availability of a federal and appropriate state
securities law exemptions.

                                       6
<PAGE>

     15.  Withholding of Additional Income Taxes.  It will be a condition of the
          --------------------------------------
Company's obligation to issue Common Stock or make any payment upon exercise of
a Stock Right that the person exercising the Stock Right pay, or make provision
satisfactory to the Company for the payment of, any taxes which the Company is
obligated to collect in connection with such issuance or payment.

     16.  Governing Law.  This Plan and any agreements entered into under this
          -------------
Plan will be governed and construed in accordance with the laws of the
Commonwealth of Massachusetts.

     17.  Effective Date.  This Plan is effective as of September 13, 1999, the
          --------------
date of its adoption by the Board.  Unless previously terminated, the Plan will
terminate at midnight on September 12, 2009 and no Stock Right may be granted
after such date.
