and, or for an injunction against a violation of any of the terms hereof or

Directors of the Company to be increased by the number of the New Director

 ----
eight (8) members), and to elect to such newly-created directorship such
individual as the Majority Holders shall in their sole and absolute discretion
have designated in a written notice or notices delivered to the Company (the
"Notice") and the Company shall inform the Principal Shareholders of the Company
of such designation and of their obligations with respect thereto pursuant to
the Shareholders' Agreement.

          Any New Director who shall have been designated by the Investors
pursuant to this Section 6.3 may be removed at any time, either with or without
                 -----------
cause, but only as the Majority Holders may determine and any vacancy created by

                                                                  -----------

     plus a premium equal to a fifty percent (50%) compounded annual rate of
     return on the Purchase Price, and (B) the fair market value of the Common
     Stock (i.e., the closing price of the Common Stock on the AMEX (or if such
     shares are no longer listed on the AMEX, any other applicable exchange or
     public listing)), if applicable, averaged for the twenty (20) trading days
     ending on the day prior to the day of the occurrence of the Event of
     Default triggering the Put) (the "Put Purchase Price").

                    (ii) The Company shall pay the Put Purchase Price to the
     Investors within sixty (60) days after such Event of Default, except that
     the Company shall pay the Put Purchase Price to the Investors within one
     hundred (100) days thereof if the applicable Put was triggered by an Event
     of Default pursuant to Section 6.1(i).
                            --------------

not provide his consent to any of the actions set forth in Section 5.3 and the
                                                           -----------
Board of Directors of the Company authorizes, approves or ratifies any such
action, the Company may exercise its option to purchase from the Investors all

exercise of the Call by the Company, sell to the Company all of the Investor
Common Stock.

                    (i)  Upon the exercise of the Call, the Company shall pay
     the Investors (pro-rata in accordance with the number of shares of Investor
     Common Stock each Investor owns) for all of the Investor Common Stock, in a
     lump sum for cash an amount equal to the greater of (a) the Purchase Price,
     plus a premium equal to a fifty percent (50%) compounded annual rate of
     ----
     return on the Purchase Price, and (b) the fair market value of the Common
     Stock (i.e., the closing price of the Common Stock on the AMEX (or if such
            ----
     shares are no longer listed on the AMEX, any other applicable exchange or
     public listing)), if applicable, averaged for the twenty (20) trading days
     ending on the day prior to the day of the meeting of the Board of Directors
     of the Company whereby the Board of Directors of the Company authorized,
     approved or ratified the action in question triggering the Call (the "Call
     Purchase Price").

                    (ii) The Company shall pay the Call Purchase Price to the
     Investors within sixty (60) days after the meeting of the Board of
     Directors of the Company whereby such Investor Representative did not
     approve such action.

               (c)  Notice of Put/Call. Any Put or Call granted under this
                    ------------------
Section 6.4 may be exercised from time to time by notice in writing, which
-----------
notice must be given within forty five (45) days with respect to a Call and five
(5) days with respect to a Put, of the occurrence of any event triggering such
Put or Call, to the Company in the case of a Put, or to the Investors in

                                      -26-
<PAGE>

the case of a Call (the "Notice"). The Notice shall state that such Put or Call,
as the case may be, is exercised. In each case, the Company shall provide to
each Investor a written statement of the dollar amount and the supporting
calculations of the Put Purchase Price or the Call Purchase Price, as the case
may be, at least ten (10) days prior to the date upon which the Put Purchase
Price or the Call Purchase Price, as the case may be, shall be payable and due,
which shall state the date and time of the closing thereof (which date shall be
in accordance with Section 6.4(a)(ii) or Section 6.4(b)(ii), as applicable) at
                   ------------------    ------------------
the principal office of the Company.

          (d)  Exercise Procedure. In the event that any Put or Call under this
               ------------------
Section 6.4 is exercised, delivery of the certificate or certificates evidencing
-----------
the shares involved, properly endorsed for transfer, shall be made by the
Investors against full payment therefor in the manner and at the time or times
specified in Section 6.4(a)(ii) or Section 6.4(b)(ii) hereof, as applicable.
             ------------------    ------------------

          (e)  Compounded Annual Rate of Return.  It is understood and agreed
               --------------------------------
that in calculating the premium on the Purchase Price based on a 50% "compounded
annual rate of return" for purposes of this Section 6.4, such 50% return shall
be added to and calculated based on the Purchase Price for each anniversary date
hereof (or a pro rata portion for a partial year) plus the amount of any
previous 50% return calculated for each prior one (1) year period after the date
of this Agreement. For instance, the 50% "compounded annual rate of return" (not
including the Purchase Price amount) on the day after the second anniversary of
this Agreement would be equal to $14,125,000 and is calculated as follows: (i)
$11,300,000 (the Purchase Price) x 50% = $5,650,000 ("First Year Return"); plus
(ii) $16,950,000 (Purchase Price plus First Year Return) x 50% $8,475,000).

     Section 7. Miscellaneous.
                -------------

               (b)  Such Investor has been furnished any and all material

liable for any claim arising out of, or based upon, (i) the investment by any
Investor in any Person competitive to the Company, or (ii) actions taken by any
partner, officer or other representative of any Investor to assist any such
competitive company, whether or not such action was taken as a board member of
such competitive company, or otherwise, and whether or not such action has a
detrimental effect on the Company.

          7.4  Notices. Any and all notices or other communications required or
               -------
