offer contained in the Tag-Along Notice, the Investor shall notify the Selling
Stockholder in writing within 20 days after receipt of the Tag-Along Notice,

respect to the Proposed Sale and the Selling Stockholder shall be free to sell
its Shares to the Proposed Buyer pursuant to the Proposed Sale without any
further obligations to such Investor.  Any acceptance by an Investor of the
offer contained in the Tag-Along Notice shall be irrevocable except as
hereinafter provided.  If an Investor elects to participate in such Proposed
Sale it shall be entitled to sell in the Proposed Sale, on the same terms and
conditions as the Selling Stockholder, the lesser of (a) the number of shares

          --------------------------
execute such documents and instruments as shall be reasonably necessary in order
to consummate the Proposed Sale expeditiously on the same terms as the Selling
Stockholder. If at the end of 180 days following the date on which the Tag-Along
Notice was given the Selling Stockholder has not completed the Proposed Sale in
accordance with the terms hereof, the Investors shall be released from their
obligations hereunder unless the failure to complete the Proposed Sale resulted
from the failure of any of the Investors to comply with the terms of Sections
3.2 or 3.3. At the closing of any sale under this Section 3.3, the Investors
participating in the Proposed Sale shall deliver certificates representing the
Investor Securities to be sold by it, duly endorsed for transfer and with any
stock transfer tax stamps affixed, against delivery of the applicable purchase
price. Any shares sold to the Proposed Buyer in accordance with this Section 3.3

               such Management Stockholder's employment by such Management
               Stockholder then, in any such event, the Company may purchase all

               amount equal to such balance.  The principal of such note will be
               due and payable in three equal annual installments, the first
               such installment becoming due and payable on the first
               anniversary of the issuance of such note, and interest will

               principal of such note will be due and payable in four equal
               annual installments, the first such installment becoming due and
               payable on the first anniversary of the issuance of such note,
               and interest will accrue thereon at a rate equal to the
               applicable federal rate and be payable annually in arrears, in
               each case subject to the provisions of Section 4.3.

of Shares issued to a Management Shareholder to options, within 180 days of the
later of the date the subject option was exercised and the effectiveness of the

Call Notice shall state that the Company has elected to exercise the Call
Option, and the number and price of the Shares with respect to which the Call
Option is being exercised.

               ----------

     4.2. Repurchase upon Death of Management Stockholder.  Upon any termination
          -----------------------------------------------
of employment by the Company and its subsidiaries due to the death of any
Management Stockholder who was a Management Shareholder on the date hereof, the

all of the Shares held by such Management Stockholder on the following terms:

          (a)  The Company shall purchase all of the Shares held by such
Management Stockholder at a per Share price equal to the Fair Market Value of
such Shares on the date of the Management Stockholder's death.

          (b)  Subject to the provisions of Section 4.3, in each case Shares are
purchased pursuant to clause (a) above, the Company will pay for such Shares
from the proceeds of the life insurance policies maintained by the Company
insuring the deceased Management Stockholder (as provided in Section 7.3(b)
below).  In the event the Company cannot maintain a life insurance policy on a
Management Stockholder, for whatever reason, or the proceeds of the life
insurance policy on the deceased Management Stockholder is not sufficient to pay
the entire purchase price for the Shares, the Company shall pay for such Shares
by (i) paying the estate of the deceased Management Stockholder cash in the
amount of insurance proceeds, if any, and (ii) issuing for the balance of the
purchase price not so paid in cash a subordinated promissory note in a principal
amount equal to such balance.  The principal of such note will be due and
payable in three equal annual installments, the first such installment becoming
due and payable on the first anniversary of the issuance of such note, and
interest will accrue thereon at a rate equal to the applicable federal rate and
be payable annually in arrears, in each case subject to the provisions of
Section 4.3.

constitute, result in or give rise to any breach or violation of, or any default
or right or cause of action under, any agreement to which the Company or any of
its subsidiaries is, from time to time, a party or (b) leave the Company and its
subsidiaries with less cash than, in the good faith judgment of the Board, is
necessary to operate the business of the Company and its subsidiaries in the
ordinary course of business, then,

                                      -15-
<PAGE>

          (a)  in the case of a cash payment due at a closing of any purchase
and sale of Shares to the Company upon the exercise of any Call Option, the
Company will issue a promissory note in the aggregate principal amount of such
payment, the principal amount of which note will be due and payable in four
equal annual installments, the first such installment becoming due and payable
on the first anniversary of the issuance of such note, and interest will accrue
thereon at a rate equal to the applicable federal rate and be payable annually
in arrears, in each case subject to the provisions of clause (b) below, and

          (b)  in the case of the cash payment in respect of a promissory note
issued under this Section 4, notwithstanding any of the provisions of such note,
including without limitation, the stated maturity of such note and the stated
date on which interest payments are due, such payment will not become due and
payable until such time as such payment can be made without violating any such
agreement and not resulting in the Company and its subsidiaries having less cash
than the Board determines is necessary to operate the business as contemplated
above.

duly endorsed, for transfer with signature guaranteed, free and clear of any
