Company, or an entity controlled by the Company) (a "Person"), is or becomes the

deemed to result in a Change in Control: (A) any acquisition directly from the
Company; or (B) any acquisition by merger, consolidation, share exchange or
similar transaction that is not described in clause (ii) of this Section 1(b) as
long as no Person resulting from such transaction obtains beneficial ownership
of fifty percent (50%) or more of the then Outstanding Voting Securities or (ii)
a consolidation, share exchange or similar transaction involving the Company in
which the shareholders of the Company immediately prior to such transaction do
not own, directly or indirectly, at least fifty percent (50%) of the Outstanding
Voting Securities or voting power of the issued and outstanding capital stock of
the Company's successor immediately after such transaction.

         4.       ADJUSTMENTS OF EXERCISE PRICE AND SHARES.

                  (a)      Subject to any required action by the shareholders of
the Company, the number of shares of Common Stock covered by this Option (as
well as the Exercise Price covered by this Option) shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, payment of a stock dividend with respect to
the Common Stock or any other increase or decrease in the number of issued
shares of Common Stock effected without receipt of consideration by the Company.
Such adjustment shall be made by the Board of Directors in its sole discretion,
which adjustment shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to this Option.

                  (b)      In the event of the dissolution or liquidation of the
Company, other than pursuant to a Reorganization (hereinafter defined), this
Option shall terminate as of a date to be fixed by the Board of Directors,
provided that not less than 30 days written notice of the date so fixed shall be
given to the Optionholder and the Optionholder shall have the right during such
period to exercise this Option as to all or any part of the shares of Common
Stock covered hereby.

                  (c)      In the event of a Reorganization in which the Company
is not the surviving or acquiring company, or in which the Company is or becomes
a wholly-owned subsidiary of another company after the effective date of the
Reorganization, then

                  (i)      if there is no plan or agreement respecting the
                           Reorganization ("Reorganization Agreement") or if the
                           Reorganization Agreement does not specifically
                           provide for the change, conversion or exchange of the
                           shares of Common Stock under outstanding unexercised
                           options of the Company for securities of another
                           corporation, then the Board of Directors shall take
                           such action, and this Option shall terminate, as
                           provided above; or

                  (ii)     if there is a Reorganization Agreement and if the
                           Reorganization Agreement specifically provides for
                           the change, conversion or exchange of the shares
                           under outstanding or unexercised options for
                           securities of another corporation, then the Board of
                           Directors shall adjust the shares of Common Stock
                           under this Option in a manner not inconsistent with
                           the provisions of the Reorganization Agreement for
                           the adjustment, change, conversion or exchange of
                           such options.

                  The term "Reorganization" as used in this Section 4(c) shall
mean any statutory merger, statutory consolidation, sale of all or substantially
all of the assets of the Company, or sale, pursuant to an agreement with the
Company, of securities of the Company pursuant to which


                                      -3-
<PAGE>

the Company is or becomes a wholly-owned subsidiary of another company after the
effective date of the Reorganization.

                  (d)      Except as provided above in Section 4(b) or (c) and
except as otherwise provided by the Board of Directors in its sole discretion,
this Option shall terminate immediately prior to the consummation of such
proposed action.

         5.       ADJUSTMENT TO EXERCISE PRICE.

                  The Company may, in its sole discretion, lower the Exercise
Price at any time, or from time-to-time. When any adjustment is made in the
Exercise Price, the Company shall cause a copy of such statement to be mailed to
the Optionholder, as of a date within ten (10) days after the date when the
Exercise Price has been adjusted.

         6.       MANNER OF EXERCISE.

                  Subject to Section 4, the Optionholder of this Option
