exercise of this Warrant, as adjusted from time to time.

         SECTION 1. EXERCISE OF WARRANT.

             (a) This Warrant may be exercised in whole or in part on any
business day (the "Exercise Date") and on or before the Expiration Date by
presentation and surrender hereof to the Company at its principal office at the
following address: 2 Seaport Lane, Boston, MA 02110, or at the office of its
stock transfer or warrant agent, if any, (or at such other address as the
Company may hereafter notify the Holder in writing) with the Purchase Form
annexed hereto duly executed and accompanied by proper payment of the Exercise
Price in lawful money of the United States of America in the form of a check,
subject to collection, for the number of Warrant Shares specified in the
Purchase Form. If this Warrant should be exercised in part only, the Company
shall, upon surrender of this Warrant, execute and deliver a new Warrant
evidencing the rights of the Holder thereof to purchase the balance of the
Warrant Shares purchasable hereunder. Upon receipt by the Company of this
Warrant and such Purchase Form, together with proper payment of the Exercise
Price, at such office, the Holder shall be deemed to be the holder of record of
the Warrant Shares, notwithstanding that the stock transfer books of the Company
shall then be closed or that the certificates representing such Warrant Shares
shall not then be actually delivered to the Holder. The Company shall pay any
and all documentary stamp or similar issue or transfer taxes payable in respect
of the issue or delivery of the Warrant Shares.

             (b) Notwithstanding the provisions of paragraph (a), the Holder
may, at its sole option, elect to exercise this Warrant in whole or in part by
receiving Warrant Shares equal to the value (as determined below) of this
Warrant, or any part hereof, upon surrender of the Warrant at the principal
office of the Company together with notice of such election in which event the
Company shall issue to the Holder a number of Warrant Shares calculated on the
basis of the following formula:

                           X =      Y(A-B)
                                    ------
                                       A

      Where:   X =  the number of Warrant Shares to be issued to the Holder

               Y =  the number of Warrant Shares to be exercised under
                    this Warrant

               A =  the current fair market value of one share of Common Stock
                    calculated  (determined in the manner set forth in
                    Section 3) as of the last business day immediately
                    preceding the exercise of this Warrant

                    B =      the Exercise Price

         Section 2. RESERVATION OF SHARES. The Company shall reserve at all
times for issuance and delivery upon exercise or conversion of this Warrant all
shares of its Common Stock or other shares of Capital Stock of the Company from
time to time issuable upon exercise of this Warrant. All such shares shall be
duly authorized and, when issued upon the exercise or conversion of this Warrant
in accordance with the terms hereof, including payment of the applicable
Exercise Price in full, shall be validly issued, fully paid and nonassessable,
free and clear of all liens, security interests, charges and other encumbrances
or restrictions ("Liens") on sale (other than (i) restrictions pursuant to
applicable federal and state securities laws, and (ii) any Liens created by any
action or inaction of the Holder of the Warrant Shares) and free and clear of
all preemptive rights. If the Common Stock is listed on any national securities
exchange or The NASDAQ National Market, the Company shall also list such shares
on such exchange subject to notice of issuance or maintain the listing of its
Common Stock on The NASDAQ National Market, as the case may be.


                                       2

         Section 3. FRACTIONAL INTEREST. The Company will not issue a fractional
share of Common Stock or scrip upon any exercise or conversion of this Warrant.
Instead, the Company will deliver its check for the current market value of the
fractional share. The current market value of a fraction of a share shall be
determined by multiplying the current market price of a full share by the
fraction of the share and rounding the result to the nearest cent.

         The current market value of a share of Common Stock for purposes of
this Section shall be determined as follows:

                  (i) If the Common Stock is listed on a national securities
         exchange or admitted to unlisted trading privileges on such exchange or
         listed for trading on The NASDAQ National Market, the current market
         value shall be the last reported sale price of the Common Stock on such
         exchange or Market on the last business day prior to the date of
         exercise or conversion of this Warrant or if no such sale is made on
         such day, the average closing bid and asked prices for such day on such
         exchange or Market; or

                  (ii) If the Common Stock is not so listed or admitted to
         unlisted trading privileges, the current market value shall be the mean
         of the last reported bid and asked prices reported by the National
         Quotation Bureau, Inc., on the last business day prior to the date of
         exercise or conversion; or

                  (iii) If the Common Stock is not so listed or admitted to
         unlisted trading privileges and bid and asked prices are not so
         reported, the current market value per share shall be an amount
         determined in such reasonable manner as may be prescribed in good faith
         by the Board of Directors of the Company.

         Section 4. EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.

             (a) Except as otherwise provided in SECTION 8, the Holder of this
Warrant shall be entitled, at its option, without expense and without obtaining
the consent of the Company, to assign its interest in this Warrant, or any of
the Warrant Shares, in whole or in part, upon presentation and surrender hereof
to the Company or its stock transfer agent, if any; PROVIDED, HOWEVER, that the
transferee, prior to any such transfer, agrees in writing, in form and substance
satisfactory to the Company, to be bound by the terms of this Warrant and
provides the Company with an opinion of counsel in such form reasonably
acceptable to the Company, that such transfer would not be in violation of the
Act or any applicable state securities or blue sky laws.

             (b) Subject to the provisions of SECTION 8, upon surrender of this
Warrant to the Company or at the office of its stock transfer agent or warrant
agent, with the Assignment Form annexed hereto duly executed and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant or Warrants in the name of the assignee or assignees
named in such instrument of assignment and, if the Holder's entire interest is
not being assigned, in the name of the Holder, and this Warrant shall promptly
be canceled.

             (c) This Warrant may be divided by or combined with other Warrants
which carry the same rights upon presentation hereof at the principal office of
the Company or at the office of its stock transfer or warrant agent, if any,
together with a written notice specifying the names and denominations in


                                       3
<PAGE>

which new Warrants are to be issued and signed by the Holder hereof. The term
"Warrant" as used herein includes any warrants into which this Warrant may be
divided or exchanged.

             (d) This Warrant is exchangeable, upon the surrender thereof by the
Holder at the principal office of the Company, for new Warrants of like tenor
registered in the Holder's name and representing in the aggregate the right to
purchase the number of shares purchasable under the Warrant being exchanged,
each of such new Warrants to represent the right to subscribe for and purchase
such number of shares as shall be designated by the Holder at the time of such
surrender.

         Section 5. RIGHTS OF THE HOLDER. The Holder shall not, by virtue
hereof, be entitled to any rights of a stockholder in the Company, either at law
or equity, and the rights of the Holder are limited to those set forth in this
Warrant.

         Section 6. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

             (a) RECLASSIFICATION, CONSOLIDATION OR MERGER. In case of any
reclassification or change of outstanding securities issuable upon exercise or
conversion of this Warrant (other than a change in par value, or from par value
to no par value, or from no par value to par value or as a result of a
subdivision or combination) or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with another
corporation in which the Company is a continuing corporation and which does not
result in any reclassification or change, other than a change in par value, or
from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination of outstanding securities issuable upon
the exercise of this Warrant), the Company, or such successor or purchasing
corporation, as the case may be, shall, without payment of any additional
consideration therefor, execute a new warrant providing that the Holder of the
Warrant shall have the right to exercise such new warrant (upon terms not less
favorable to the Holder than those then applicable to this Warrant) and to
receive upon such exercise, in lieu of each share of Common Stock theretofore
issuable upon exercise or conversion of this Warrant, the kind and amount of
shares of stock, other securities, money or property receivable upon such
reclassification, change, consolidation or merger by the Holder of one share of
Common Stock issuable upon exercise or conversion of this Warrant had the
Warrants been exercised or converted immediately prior to such reclassification,
change, consolidation, or merger. Such new warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this SECTION 6. The provisions of this SUBSECTION 6(a) shall
similarly apply to successive reclassifications, changes, consolidations, or
mergers.

             (b) SUBDIVISION OR COMBINATION OF SHARES. If the Company at any
time while this Warrant remains outstanding and unexpired, shall subdivide or
combine its Capital Stock, the Exercise Price shall be proportionately reduced,
in case of subdivision of shares, as of the effective date of such subdivision,
or, if the Company shall take a record of holders of its Capital Stock for the
purpose of so subdividing, as of such record date, whichever is earlier, or
shall be proportionately increased, in the case of combination of shares, as of
the effective date of such combination, or, if the Company shall take a record
of holders of its Capital Stock for the purpose of so combining, as of such
record date, whichever is earlier.

             (c) CERTAIN DIVIDENDS AND DISTRIBUTIONS. If the Company at any time
while this Warrant is outstanding and unexpired shall:


                                       4
<PAGE>

                  (i) STOCK DIVIDENDS. Pay a dividend in shares of, or make
         another distribution of shares of, its Capital Stock, then the Exercise
         Price shall be adjusted, as of the date the Company shall take a record
         of the holders of its Capital Stock for the purpose of receiving such
         dividend or other distribution (or if no such record is taken, as at
         the date of such payment or other distribution), to that price
         determined by multiplying that Exercise Price in effect immediately
         prior to such payment or other distribution by a fraction (a) the
         numerator of which shall be the total number of shares of Capital Stock
         outstanding immediately prior to such dividend or distribution, and (b)
         the denominator of which shall be the total number of shares of Capital
         Stock outstanding immediately after such dividend or distribution; or

                  (ii) LIQUIDATING DIVIDENDS, ETC. Make a distribution of its
         assets to the holders of its Capital Stock as a dividend in liquidation
         or by way of return of capital or other than as a dividend payable out
         of earnings or surplus legally available for dividends under applicable
         law, the Holder shall, upon its exercise, be entitled to receive, in
         addition to the number of shares of Common Stock receivable thereupon,
         and without payment of any additional consideration therefor, a sum
         equal to the amount of such assets as would have been payable to it as
         owner of that number of shares of Common Stock receivable by exercise
         or conversion of the Warrant had it been the Holder of record of such
         Common Stock on the record date for such distribution, or if no such
         record is taken, as of the date of such distribution, and an
         appropriate provision therefor shall be made a part of any such
         distribution.

             (d) ISSUANCE OF ADDITIONAL SHARES OF CAPITAL STOCK. If the Company
at any time while this Warrant remains outstanding and unexpired shall issue any
Additional Shares of Capital Stock (otherwise than as provided in the foregoing
SUBSECTIONS (6)(a) through (6)(c) above) at a price per share less, or for other
consideration lower, than the Exercise Price, or without consideration, then
upon such issuance the Exercise Price shall be adjusted to the price per share
paid for such Additional Shares of Common Stock (but not less than the par value
of the Common Stock). The provisions of this SUBSECTION 6(d) shall not apply
under any of the circumstances for which an adjustment is provided in
SUBSECTIONS 6(a), 6(b) or 6(c). No adjustment of the Exercise Price shall be
made under this SUBSECTION 6(d) upon the issuance of any Additional Shares of
Capital Stock which are issued pursuant to the exercise of any warrants, options
or other subscription or purchase rights or pursuant to the exercise of any
conversion or exchange rights in any convertible securities if any such
adjustments shall previously have been made upon the issuance of any such
warrants, options or other rights or upon the issuance of any convertible
securities (or upon the issuance of any warrants, options or any rights
therefor) pursuant to SUBSECTIONS 6(e) or 6(f) hereof.

             (e) ISSUANCE OF WARRANTS, OPTIONS OR OTHER RIGHTS. In case the
Company shall issue any warrants, options or other rights to subscribe for or
purchase any Additional Shares of Capital Stock and the price per share for
which Additional Shares of Capital Stock may at any time thereafter be issuable
pursuant to such warrants, options or other rights shall be less than the
Exercise Price per share of Common Stock hereunder, then upon such issuance the
Exercise Price shall be adjusted as provided in SUBSECTION 6(d) hereof on the
basis that the aggregate consideration for the Additional Shares of Capital
Stock issuable pursuant to such warrants, options or other rights, shall be
deemed to be the consideration received by the Company for the issuance of such
warrants, options, or other rights plus the minimum consideration to be received
by the Company for the issuance of Additional Shares of Capital Stock pursuant
to such warrants, options, or other rights.

             (f) ISSUANCE OF CONVERTIBLE SECURITIES. In case the Company shall
issue any securities (debt or equity) convertible into Additional Shares of
Capital Stock and the consideration per share for which Additional Shares of
Capital Stock may at any time thereafter be issuable pursuant to the


                                       5
<PAGE>

terms of such convertible securities shall be less than the Exercise Price, then
upon such issuance the Exercise Price shall be adjusted as provided in
SUBSECTION 6(d) hereof on the basis that (i) the maximum number of Additional
Shares of Capital Stock necessary to effect the conversion or exchange of all
such convertible securities shall be deemed to have been issued as of the date
of issuance of such convertible securities, and (ii) the aggregate consideration
for such maximum number of Additional Shares of Capital Stock shall be deemed to
be the minimum consideration received by the Company for the issuance of such
Additional Shares of Capital Stock pursuant to the terms of such convertible
securities. No adjustment of the Exercise Price shall be made under this
subsection upon the issuance of any convertible securities which are issued
pursuant to the exercise of any warrants or other subscription or purchase
rights therefor, if any such adjustment shall previously have been made upon the
issuance of such warrants or other rights pursuant to SUBSECTION 6(e) hereof.

             (g) ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment in the
Exercise Price pursuant to any provisions of this SECTION 6, the number of
shares of Common Stock purchasable hereunder shall be adjusted, to the nearest
one hundredth of a whole share, to the product obtained by multiplying such
number of shares purchasable immediately prior to such adjustment by a fraction,
the numerator of which shall be the Exercise Price immediately prior to such
adjustment and the denominator of which shall be the Exercise Price immediately
thereafter.

             (h) OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS SECTION.
The following provisions will be applicable to the making of adjustments in the
Exercise Price hereinabove provided in this SECTION 6:

                  (i) COMPUTATION OF CONSIDERATION. To the extent that any
         Additional Shares of Capital Stock or any convertible securities (debt
         or equity) or any warrants, options or other rights to subscribe for or
         purchase any Additional Shares of Capital Stock or any convertible
         securities (debt or equity) shall be issued for a cash consideration,
         the consideration received by the Company therefor shall be deemed to
         be the amount of the cash received by the Company therefor, or, if such
         Additional Shares of Capital Stock or convertible securities (debt or
         equity) are offered by the Company for subscription, the subscription
         price, or, if such Additional Shares of Capital Stock or convertible
         securities (debt or equity) are sold to underwriters or dealers for
         public offering without a subscription offering, or through
         underwriters or dealers for public offering without a subscription
         offering, the initial public offering price, in any such case excluding
         any amounts paid or incurred by the Company for and in the underwriting
         of, or otherwise in connection with the issue thereof. To the extent
         that such issuance shall be for a consideration other than cash, then,
         except as herein otherwise expressly provided, the amount of such
         consideration shall be deemed to be the fair value of such
         consideration at the time of such issuance as determined in good faith
         by the Company's Board of Directors. The consideration for any
         Additional Shares of Capital Stock issuable pursuant to any warrants,
         options or other rights to subscribe for or purchase the same shall be
         the consideration received by the Company for issuing such warrants,
         options or other rights, plus the additional consideration payable to
         the Company upon the exercise of such warrants, options or other
         rights. The consideration for any Additional Shares of Capital Stock
         issuable pursuant to the terms of any convertible securities (debt or
         equity) shall be the consideration paid or payable to the Company in
         respect of the subscription for or purchase of such convertible
         securities, plus the additional consideration, if any, payable to the
         Company upon the exercise of the right of conversion or exchange in
         such convertible securities. In case of the issuance at any time of any
         Additional Shares of Capital Stock or convertible securities (debt or
         equity) in payment or satisfaction of any dividend upon any class of
         stock preferred as to dividends in a fixed amount, the Company shall be
         deemed to have received for such Additional Shares of Capital Stock or
         convertible securities a consideration equal to the amount of such
         dividend so paid or satisfied.


                                       6
<PAGE>

                  (ii) READJUSTMENT OF EXERCISE PRICE. Upon the expiration of
         the right to convert or exchange any convertible securities (debt or
         equity), or upon the expiration of any rights, options or warrants, the
         issuance of which convertible securities, rights, options or warrants
         effected an adjustment in the Exercise Price, if any such convertible
         securities shall not have been converted or exchanged, or if any such
         rights, options or warrants shall not have been exercised, the number
         of shares of Capital Stock deemed to be issued and outstanding by
         reason of the fact that they were issuable upon conversion or exchange
         of any such convertible securities or upon exercise of any such rights,
         options, or warrants shall no longer be computed as set forth above,
         and such Exercise Price shall forthwith be readjusted and thereafter be
         the price which it would have been (but reflecting any other
         adjustments in the Exercise Price made pursuant to the provisions of
         this SECTION 6 after the issuance of such convertible securities,
         rights, options or warrants) had the adjustment of the Exercise Price
         made upon the issuance or sale of such convertible securities or
         issuance of rights, options or warrants been made on the basis of the
         issuance only of the number of Additional Shares of Capital Stock
         actually issued upon conversion or exchange of such convertible
         securities, or upon the exercise of such rights, options or warrants,
         and thereupon only the number of Additional Shares of Capital Stock
         actually so issued shall be deemed to have been issued and only the
         consideration actually received by the Company (computed as in
         SUBSECTION (6)(h)(i) hereof) shall be deemed to have been received by
         the Company.

                  (iii) TREASURY SHARES. The number of shares of Capital Stock
         at any time outstanding shall not include any shares thereof then
         directly or indirectly owned or held by or for the account of the
         Company.

                  (iv) OTHER ACTION AFFECTING CAPITAL STOCK. In case after the
         date hereof the Company shall take any action affecting the Capital
         Stock, other than an action described in any of the foregoing
         SUBSECTIONS (6)(a) to (6)(f) hereof, inclusive, which in the opinion of
         the Company's Board of Directors would have a materially adverse effect
         upon the rights of the Holder to purchase the Warrant Shares, the
         Exercise Price shall be adjusted in such manner and at such time as the
         Board of Directors may in good faith determine to be equitable in the
         circumstances.

                  (i) NOTICE OF CERTAIN ACTIONS. In the event that:

                  (i) the Company shall authorize the issuance to all holders of
         its Common Stock of rights, warrants, options or convertible securities
         to subscribe for or purchase shares of its Common Stock or of any other
         subscription rights, warrants, options or convertible securities; or
         (ii) the Company shall authorize the distribution to all holders of its
         Common Stock of evidences of its indebtedness or assets (other than
         dividends paid in or distributions of the Company's Capital Stock for
         which the Exercise Price shall have been adjusted pursuant to
         SUBSECTION (6)(a) or cash dividends or cash distributions payable out
         of consolidated current or retained earnings as shown on the books of
         the Company and paid in the ordinary course of business); or (iii) the
         Company shall authorize any capital reorganization or reclassification
         of the Common Stock (other than a subdivision or combination of the
         outstanding Common Stock and other than a change in par value of the
         Common Stock) or of any consolidation or merger to which the Company is
         a party and for which approval of any shareholders of the Company is
         required (other than a consolidation or merger in which the Company is
