<PAGE>

                           c.   the Company earns $26.4 million in Net
                                Income, then the 10-year lock-up shall
                                terminate completely as to 50% of the 2006
                                Lock-Up Shares.
                           (iv) Any 10-Year Lock-Up Shares not released from
                                the 10-year lock-up in each of the eighteen
                                months ending December 31, 2004, 2005 or
                                2006, are eligible for release from the
                                10-Year Lock-Up if the COmpany meets the net
                                income hurdles on a cumulative basis. By
                                way of example, if cumulative Net Income for
                                the eighteen months ending December 31, 2004
                                and 2005 is greater than $46 million,
                                then the 10-year lock-up shall terminate
                                completely as to 60% of the 10-Year Lock-Up
                                Shares. Likewise, if cumulative Net Income
                                for 2006 exceeds $79 million, then the
                                10-year lock-up shall completely terminate
                                as to 100% of the 10-Year Lock-Up Shares.

                  4. Recapitalization. Any new, substituted or additional
securities or other property (including cash paid other than as a regular cash
dividend) which is by reason of any Recapitalization distributed with respect to
the 10-Year Lock-Up Shares shall be immediately subject to the same lock-up
provisions. Appropriate adjustments to reflect such distribution shall be made
to the number of 10-Year Lock-Up Shares subject to this Agreement.

                  5. Corporate Transaction.

                           (a) The restriction on transfer hereunder shall
         automatically terminate in its entirety, and all the 10-Year Lock-Up
         Shares shall be free from restriction hereunder immediately prior to
         the consummation of:

                                    (i) a merger or consolidation in which
         securities possessing more than fifty percent (50%) of the total
         combined voting power of the Corporation's outstanding securities are
         transferred to a person or persons different from the persons holding
         those securities immediately prior to such transaction, or

                                    (ii) the sale, transfer or other disposition
         of all or substantially all of the Corporation's assets in complete
         liquidation or dissolution of the Corporation any Corporate
         Transaction.
