         ----------------------
Stock Purchase Agreement dated as of March 1, 2000 (the "Purchase Agreement")
pursuant to which they have received, or are receiving, certain Shares from the
Corporation.  The Shareholders believe that their best interests and those of
the Corporation will be served by preserving harmony and continuity with respect
to the management and capital stock of the Corporation, and that these goals can
best be obtained by imposing restrictions on the Disposition of the Shares as
provided in this Agreement.

     3.  RESTRICTION ON DISPOSITION.
         --------------------------

               3.1.  General Restriction. Except for Dispositions to Permitted

anything to the contrary contained in this Agreement, a Shareholder may Dispose
of all or any portion of his Shares to a Permitted Transferee without complying

portion of his Shares to a Permitted Transferee, the Permitted Transferee shall
succeed to all of the rights and benefits, and be subject to all of the
restrictions under this Agreement, applicable to the Shareholder from whom the
Permitted Transferee receives his Shares. If a Shareholder who made a
Disposition to a Permitted Transferee Disposes of his Shares, such Shareholder's
Permitted Transferee(s) shall also be required to Dispose of his or its Shares
on the same terms and conditions. In the event of a Disposition to a Permitted
Transferee, each reference in this Agreement to the Shareholder making such
Disposition shall also include each Permitted Transferee of such Shareholder.

     4.  GENERAL PROCEDURES ON DISPOSITIONS.
         ----------------------------------

               4.1.  Sale Right. If a Shareholder desires to sell all or any
                     ----------
 part of a Shareholders' Shares then held or owned beneficially by such

 offer all, but not less than all, of the Offeror's Shares for sale in
 accordance with the remaining provisions of this Section 4 and the Offeror
 shall not have the right to make any Disposition of the Offeror's Shares,
 except in accordance with the remaining provisions of this Section 4.

         4.2.  Bona Fide Offer.  If the Offeror receives from any Person (a
               ---------------
"Bona Fide Offeror") a bona fide offer in writing (the "Bona Fide Offer") to
purchase all or any of the Offeror's Shares, then the Offeror shall give to the
Corporation a notice (the "Bona Fide Offer Notice") to which shall be annexed a
copy of the Bona Fide Offer containing the material terms and conditions of the
Bona Fide Offer.

               4.2.1. The Bona Fide Offer Notice shall constitute an offer (the
"Offer") on the part of the Offeror to sell to the Corporation all of the Shares
                                                               ---
owned by the Offeror and shall fix a date and time by which the Corporation must
notify the Offeror of its intent to purchase the Shares owned by such Offeror,
which date shall not be less than 10 days nor more than 30 days after the Bona
Fide Offer Notice is given.

               4.2.2. If the Corporation desires to accept the Offer, an officer
of the Corporation shall sign and deliver an acknowledgment setting forth the
number of Shares for which it desires to accept the Offer. Any such
acknowledgment shall constitute an acceptance of the Offer as to the number of
Shares set forth in the acknowledgment.

               4.2.3. If the Offer is accepted as to any of the Offeror's
Shares, the Corporation shall set a date, time and place when the purchase and
sale of the Shares shall be consummated (the "Offer Closing"), which date shall
not be less than 10 days nor more than 30 days after the date set forth in
Section 4.2.1 above. The Corporation shall be bound to purchase and the Offeror
shall be obligated to sell the Offeror's Shares at the Offer Closing.

               4.2.4. At the Offer Closing, the Offeror shall deliver all
documents which counsel for the Corporation reasonably deems necessary or
advisable in order to accomplish a complete transfer of the Shares to the
Corporation free and clear of all Liens, and the Corporation shall deliver to
the Offeror the purchase price for the Shares set forth in the Bona Fide Offer
Notice for the number of Share to be purchased by the Corporation in accordance
with the terms set forth in the Bona Fide Offer Notice.

     4.3. Failure to Exercise Right.  If the Bona Fide Offer Notice shall
          -------------------------
not be timely accepted as provided in Section 4.2.1 and therefore expires, then
the Offeror may sell his or its Shares to the Bona Fide Offeror within 60 days
from the date of the date set forth in Section 4.2.1 hereof upon the terms and
conditions set forth in the Bona Fide Offer.  If the Offeror does not consummate
the sale of his or its Shares to the Bona Fide Offeror on such terms and
conditions within such 60-day period, the Offeror shall again be required to
comply with all of the provisions of this Section 4.

     4.4. Agreement to be Bound.  Any Bona Fide Offeror who purchases Shares

Shareholder under this Agreement from the date of his or its purchase.

of the rights and benefits, and be subject to all of the restrictions under this

receives his Shares. If Shareholder makes a Disposition to a Permitted
Transferee of his Shares, such Shareholder's Permitted Transferee(s) shall also

not less than all, of the Offeror's Shares for sale in accordance with the
remaining provisions of this Section 4 and the Offeror shall not have the right
to make any Disposition of the Offeror's Shares, except in accordance with the
remaining provisions of this Section 4.
<PAGE>

          4.3.  Bona Fide Offer.  If the Offeror receives from any Person (a
                ---------------
"Bona Fide Offeror") a bona fide offer in writing (the "Bona Fide Offer") to
purchase all or any of the Offeror's Shares, then the Offeror shall give to the
Corporation a notice (the "Bona Fide Offer Notice") to which shall be annexed a
copy of the Bona Fide Offer containing the material terms and conditions of the
Bona Fide Offer.

                4.3.1.  The Bona Fide Offer Notice shall constitute an offer
(the "Offer") on the part of the Offeror to sell to the Corporation all of the
                                                                    ---
Shares owned by the Offeror and shall fix a date and time by which the
Corporation must notify the Offeror of its intent to purchase the Shares owned
by such Offeror, which date shall not be less than 10 days nor more than 30 days
after the Bona Fide Offer Notice is given.

                4.3.2.  If the Corporation desires to accept the Offer, an
officer of the Corporation shall sign and deliver an acknowledgment setting
forth its desire to accept the Offer as to all of the Shares. Any such
                                           ---
acknowledgment shall constitute an acceptance of the Offer as to all of the
Shares.

                4.3.3.  If the Offer is accepted as to any of the Offeror's
Shares, the Corporation shall set a date, time and place when the purchase and
sale of the Shares shall be consummated (the "Offer Closing"), which date shall
not be less than 10 days nor more than 30 days after the date set forth in
Section 4.3.1 above. The Corporation shall be bound to purchase and the Offeror
shall be obligated to sell the Offeror's Shares at the Offer Closing.

                4.3.4.  At the Offer Closing, the Offeror shall deliver all
documents which counsel for the Corporation reasonably deems necessary or
advisable in order to accomplish a complete transfer of the Shares to the
Corporation free and clear of all Liens, and the Corporation shall deliver to
the Offeror the purchase price for the Shares set forth in the Bona Fide Offer
Notice for the number of Share to be purchased by the Corporation in accordance
with the terms set forth in the Bona Fide Offer Notice.

          4.4.  Failure to Exercise Right.  If the Bona Fide Offer Notice shall
                -------------------------
not be timely accepted as provided in Section 4.3.1 and therefore expires, then
the Offeror may sell his or its Shares to the Bona Fide Offeror within 60 days
from the date of the date set forth in Section 4.3.1 hereof upon the terms and
conditions set forth in the Bona Fide Offer. If the Offeror does not consummate
the sale of his or its Shares to the Bona Fide Offeror on such terms and
conditions within such 60-day period, the Offeror shall again be required to
comply with all of the provisions of this Section 4.

          4.5.  Agreement to be Bound.  Any Bona Fide Offeror who purchases
                ---------------------
Shares pursuant to Section 4 or otherwise becomes the owner of the Shares shall
be deemed to have consented to his Shares being subject to and governed by the
terms of this Agreement and shall have all of the rights and obligations of a
Shareholder under this Agreement from the date of his or its purchase.

          4.6.  "Market Stand-Off" Agreement.  Shareholder hereby agrees that he

connection with a registration statement of the Corporation filed under the

                8.5.1. The terms of this Agreement have been fully negotiated by
the parties in consultation with counsel, and the wording of this Agreement has
been arrived at by all of them as a result of their joint discussions.
Accordingly, no provision of this Agreement shall be construed against a
particular party or in favor of another party merely because of which party (or
its representative) drafted or supplied the wording for such provision.

                8.5.2. Except where otherwise noted in context, all references
to "Sections" shall be deemed to refer to the sections or subsections, as
appropriate, exhibits or schedules of this Agreement.

                8.5.3. Section headings appearing in this Agreement are inserted
solely as reference aids for the ease and convenience of the reader; they shall
not be deemed to modify, limit or define the scope or substance of the
provisions they introduce, nor shall they be used in construing the intent or
effect of such provisions.

                8.5.4. Where the context requires: (i) use of the singular or
plural incorporates the other, and (ii) pronouns and modifiers in the masculine,
feminine or neuter gender shall be deemed to refer to or include the other
genders.

         8.7.   Governing Law.  This Agreement shall be governed by and
                -------------
interpreted according to the laws of Delaware, but without giving effect to
