ARTICLE III.   TRANSFER RESTRICTIONS; RIGHTS OF FIRST REFUSAL AND
------------   --------------------------------------------------
               CO-SALE.
               --------

         SECTION 3.01. NO TRANSFER. No Stockholder may sell, pledge, give,
assign, distribute, hypothecate, mortgage or transfer (all hereinafter referred
to as "TRANSFER") any Stock owned by such Stockholder, directly or indirectly,
to any other person or entity, except (a) after January 1, 2000 and upon
compliance with the other provisions of this Article III or (b) as permitted by
Section 3.05.

         SECTION 3.02. OFFER TO COMPANY AND STOCKHOLDERS; CO-SALE. If a
Stockholder (the "TRANSFERRING STOCKHOLDER") desires to transfer any of such
Stockholder's shares of Stock, such Stockholder shall first offer such shares
to the Company and the other Stockholders by written notice (the "INITIAL
NOTICE") stating the name of the proposed transferee, the number of shares such
Stockholder desires to transfer and the proposed price



                                      -2-


<PAGE>   3



(expressed in U.S. dollars) and terms of transfer (which shall be for cash
payable at the time of transfer). The Company and the other Stockholders shall
then have 30 days within which to give notice (the "RETURN NOTICE") of the
maximum number of such shares they wish to acquire at the specified price and
terms. Copies of each Return Notice shall be sent to the Company and to the
other Stockholders.

         Subject to any applicable restrictions on the Company (including
without limitation under the Investment Agreement), the Company shall be
entitled to purchase any or all of the shares offered. If the Company elects to
purchase fewer than all of the shares offered, the other Stockholders (other
than the Transferring Stockholder) shall be entitled to acquire the balance of
the shares remaining on a pro rata basis, calculated as a fraction, the
numerator of which is the number of shares of Common Stock owned by such
Stockholder and the denominator of which is the number of shares of Common
Stock owned by all Stockholders (other than the Transferring Stockholder). If
any Stockholder elects to acquire less than such Stockholder's pro rata portion
of the available Stock, the other Stockholders (other than the Transferring
Stockholder) may acquire a pro rata portion of the balance of the Stock
remaining.

         In addition to the foregoing, in the Return Notice, the other
Stockholders shall indicate whether, if the Company and the Stockholders do not
elect to acquire all Stock offered by the Transferring Stockholder, they desire
to have a proportionate number of their shares of Stock transferred in the same
transaction. In that event, the Transferring Stockholder may not transfer any
Stock unless the transferee also acquires a proportionate amount of the Stock
of each other Stockholder who requested that Stock be included in such
transfer, on the price and terms specified in the Initial Notice. For purposes
of this Section, all classes of Common Stock shall be treated as a single
class.

         SECTION 3.03.  PAYMENT. If the Company and the other Stockholders give
notice of their intention to acquire all of the shares of Stock pursuant to
Section 3.02, the Company shall, at the close of the 30-day period provided in
Section 3.02 for delivery of the Return Notice, confirm by notice to the
Transferring Stockholder and the other Stockholders the number of shares to be
acquired by the other Stockholders and by the Company. Payment for such shares
shall be delivered within 20 days thereafter at the price and on the terms
specified in the Initial Notice, against receipt from the Transferring
Stockholder of certificates for the shares purchased, duly endorsed for
transfer, free and clear of all liens, restrictions, claims and encumbrances,
except under applicable securities laws and this Agreement.



                                      -3-

         SECTION 3.04.  RIGHT TO SELL. If, at the close of the 30-day period
provided in Section 3.02 for delivery of the Return Notice, the Company and the
other Stockholders have not sent notice of their intention to acquire, in the
aggregate, all of the Stock offered, the Transferring Stockholder shall have 90
days to transfer the Stock which is not being purchased by the Company or a
Stockholder to the third party specified in the Initial Notice, together with
any additional Stock to be included in such transfer pursuant to the last
paragraph of Section 3.02, at the price and on the terms specified therein. The
Stockholders shall, in order to be entitled to have Stock transferred, deliver
on no less than 20 days' notice from the Transferring Stockholder certificates
representing the shares of Stock to be transferred, duly endorsed for transfer,
free and clear of all liens, restrictions, claims and encumbrances, except
under applicable securities laws and this Agreement.

         SECTION 3.05. EXCEPTIONS TO RESTRICTIONS. Notwithstanding any other
provision of this Agreement (other than Section 4.05), the following transfers
of Stock may be consummated without restriction:

                  (a)  Transfers of Stock of an Original Stockholder,
representing an aggregate of not more than 40% of the Stock held by such
Original Stockholder, to the trustees of a trust revocable by him alone, the
beneficiaries of which consist solely of the Original Stockholder and
transferees enumerated in Subsection (d) below;

                  (b)  Transfers of Stock between an Original Stockholder and
his guardian or conservator;

                  (c)  Transfers of Stock of a deceased Original Stockholder to
his executors or administrators or to trustees under his will and thereafter to
transferees enumerated in Subsection (d) below;

                  (d)  Transfers of Stock of an Original Stockholder,
representing an aggregate of not more than 40% of the Stock held by such
Original Stockholder, to the Original Stockholder's spouse, to any of his
children or their issue (or to custodians for the benefit of minor children or
issue), or to the Original Stockholder's parents or siblings;

                  (e)  Transfers of Stock by Boston Ventures to any of its
partners in accordance with the terms of its Agreement of Limited Partnership;
and

                  (f)  Transfers of Stock by a Stockholder to Boston Ventures at
the Subsequent Closing pursuant to the Investment Agreement.

         All Stock transferred pursuant to this Section shall remain subject to
the restrictions contained herein applicable to the initial Stockholders in the
hands of the transferee, PROVIDED, HOWEVER, that such Stock may not be further
transferred, except to a person or entity to which the initial Stockholders
could have transferred such Stock pursuant to Subsections (a) through (e)
above, without first complying with the provisions of Sections 3.02.

         SECTION 3.06. LEGENDS. All certificates representing shares of Stock
issued to a Stockholder shall bear substantially the following legend:

         THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
         RESTRICTIONS ON TRANSFER AND OTHER OBLIGATIONS CONTAINED IN A
         STOCKHOLDERS AGREEMENT BETWEEN THE COMPANY AND CERTAIN OF ITS
         STOCKHOLDERS, A COPY OF WHICH IS ON FILE WITH THE COMPANY AND WILL
         BE FURNISHED WITHOUT COST TO THE HOLDER HEREOF UPON WRITTEN
         REQUEST TO THE SECRETARY.

         SECTION 3.07.  FAILURE TO DELIVER SHARES. If any Stockholder fails to
deliver the shares of Stock to be acquired by the Company or any Stockholder
hereunder, the acquiror may elect to establish a segregated account in the
amount of the price to be paid therefor, such account to be turned over to the
Transferring Stockholder upon delivery of the certificates representing the
shares of Stock as required herein. If a segregated account is so established,
the Company shall take such action as is appropriate to transfer record title
of the shares of Stock from the Transferring Stockholder to the acquiror. Each
Stockholder hereby irrevocably grants the Company a power of attorney to
effectuate the purposes of this Section.
