Corporation (as defined in Section 2.1(b)) added incentive to continue in the
service of the Company and a more direct interest in the future success of the
operations of the Company.

1993 (the "Effective Date"), subject to approval by the affirmative votes of the
holders of a majority of the shares of the Company present or represented and
entitled to vote at a meeting duly held (in person or through written consent)
in accordance with governing law within one year following the Effective Date.
If the stockholders of the Company do not approve the Plan as specified above,
Options granted under the Plan shall be deemed to be rescinded without any
further action by the Board or the Company, and the Plan shall automatically
terminate, notwithstanding any other provision in the Plan to the contrary.

pursuant to Section 3.3(d) below or fully exercised prior to the end of such

            (d) Termination of Service, Death, Etc. An Option shall terminate in
the following circumstances if the Holder ceases to be a director of the
Company:

               (i) Removal for Cause. If the Holder is removed as a director of
the Company during the Option Period for cause, the Option shall be void
thereafter for all purposes, including as to Shares for which the Option was
otherwise exercisable according to Section 3.3(g) prior to the Holder's removal
as a director of the Company.

               (ii) Disability. If the Holder ceases to be a director of the
Company on account of Disability, the Option may be exercised by the Holder (or,
in case of death thereafter, by the persons specified in Section 3.3(d)(iii))
within one year following the date on which the Holder ceased to be a director
(if otherwise within the Option Period), but not thereafter. In any such case,
the Option may be exercised only as to Shares for which the Option had become
exercisable on or before the date the Holder ceased to be a director on account
of Disability.

               (iii) Death. If the Holder dies during the Option Period while
still serving as a director or within the three-month period referred to in
Section 3.3(d)(iv) below, the Option may be exercised by those entitled to do so
under the Holder's will or by the laws of descent and distribution within one
year following the Holder's death (if otherwise within the Option Period), but
not thereafter. In any such case, the Option may be exercised only as to the
Shares for which the Option had become exercisable on or before the date of the
Holder's death.

               (iv) Other Termination. If the Holder ceases to be a director
within the Option Period for any reason other than removal for cause, Disability
or death, the Option may be exercised by the Holder within three months
following the date of such termination (if otherwise within the Option Period),
but not thereafter. In any such case, the Option may be exercised only as to the
Shares for which the Option had become exercisable on or before the date the
Holder ceased to be a director.

               (v) Extension if Holder Subject to Section 16(b). Notwithstanding
the foregoing, if a sale within the applicable time periods set forth in
Sections 3.3(d)(i), (ii), (iii), or (iv) of Shares acquired upon the exercise of
the Option would subject the Holder to suit under Section 16(b) of the Exchange
Act, the Option shall remain exercisable until the earliest to occur of (i) the
tenth (10th) day following the date on which a sale of such Shares by the Holder
would no

                                                                             -4-

after the Holder's termination of service as a director, or (iii) the expiration
of the Option Period.

               (vi) Extension if Exercise Prevented by Law. Notwithstanding the
foregoing, if the exercise of the Option within the applicable time periods set
forth in Section 3.3(d)(i), (ii), (iii) or (iv) is prevented by the provisions
of Section 3.3(e)(iv), the Option shall remain exercisable until three (3)
months after the date the Holder is notified by the Company that the Option is

during the Holder's lifetime only by the Holder or, in the event of disability
or incapacity, by the Holder's guardian or legal representative.

               (iii) Notwithstanding any other provision of the Plan, no Option
may be unconditionally granted unless and until the Plan is approved by the
stockholders of the Company in accordance with Section 1.3, and for any Option
granted prior to the time of such stockholder approval which is subject to such
approval, the date of grant of the Option shall be the date on which the
stockholders of the Company approve the Plan.

               (iv) The grant of an Option and the issuance of Shares upon
exercise of an Option shall be subject to compliance with all applicable
requirements of federal and state law with respect to such securities. An Option
may not be exercised if the issuance of Shares upon exercise would constitute a
violation of any applicable federal or state securities laws or other law or
regulations or the requirements of any stock exchange or market system upon
which the Stock may then be listed. In addition, no Option may not be exercised
unless (i) a registration statement under the Securities Act of 1933, as amended
(the "Securities Act"), shall at the time of exercise of the Option be in effect
with respect to the shares issuable upon exercise of the Option or (ii) in the
opinion of legal counsel to the Company, the shares issuable upon exercise of
the Option may be issued in accordance with the terms of an applicable exemption
from the registration requirements of the Securities Act. The inability of the
Company to obtain from any regulatory body having jurisdiction the authority, if
any, deemed by the Company's legal counsel to be necessary to the lawful
issuance and sale of any shares subject to an Option shall relieve the Company
of any liability in respect of the failure to issue or sell such shares as to
which such requisite authority shall not have been obtained. As a condition to
the exercise of an Option, the Company may require the Holder to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation and to make any representation or warranty with
respect thereto as may be requested by the Company.

                                                                             -5-

            (f) Exercise, Payments, Etc.

               (i) Method of Exercise. The method for exercising each Option
granted shall be by delivery to the Company of written notice specifying the
number of shares with respect to which the Option is exercised. The purchase of
Stock pursuant to the Option shall take place at the principal office of the
Company within thirty days following delivery of such notice, at which time the
purchase price of the Stock shall be paid in full by any of the methods set
forth in Section 3.3(f)(ii) or a combination thereof. A properly executed
certificate or certificates representing the Stock shall be delivered to the
Holder upon payment therefor.

               (ii) Payment of Option Price. The Option Price shall be paid by
any of the following methods or any combination of such methods, at the option
of the Holder: (A) cash; (B) certified, cashier's or other check acceptable to
the Company, payable to the order of the Company; (C) delivery to the Company of
certificates representing a number of shares of Stock then owned by the Holder,
the Fair Market Value of which (determined as of the date the notice of exercise
is delivered to the Company) equals the price of the Stock to be purchased
pursuant to the Option, properly endorsed for transfer to the Company; or (D) by
the assignment of the proceeds of a sale of some or all of the shares being
acquired upon the exercise of the Option (including, without limitation, through
an exercise complying with the provisions of Regulation T as promulgated from
time to time by the Board of Governors of the Federal Reserve System)
("Immediate Sales Proceeds"). No Option may be exercised by delivery to the
Company of certificates representing Stock that has been held by the Option
Holder for less than six months or such other period as shall be sufficient for
the Company to avoid, if possible, the recognition of expense with respect to
the Option for accounting purposes. The payment of the exercise price with
Immediate Sales Proceeds shall comply with procedures established by the
Company, which procedures may be changed from time to time in the Company's sole
discretion. The Company retains the right to discontinue the availability of
payment with Immediate Sales Proceeds at any time.

            (g) Service Required for Exercise. Except as set forth in Section
1.3 and 3.3(d), the Initial Grant made to an Outside Director under the Plan
shall become exercisable (i) for one-third (1/3) of the total number of shares
subject to such Option after one year of continuous service by the Holder as a
director of the Company after the date of grant and (ii) for an additional
one-third (1/3) of the total number of shares subject to the Option at the end
of each full year of continuous service as a director of the Company thereafter,
in each case rounded to the nearest whole number of shares. Except as set forth
in Sections 1.3 and 3.3(d), each subsequent Option granted to an Outside
Director under the Plan shall be exercisable in its entirety after three (3)
years of continuous service by the Holder as a director of the Company after the
date of grant. Except as set forth in Section 5.2, the Option shall not be
exercisable as to any Shares as to which the applicable continuous service
requirements has not been satisfied, regardless of the circumstances under which
the Holder ceased to be a director.

                                                                             -6-

maximum aggregate number of shares of Stock that may be issued under the Plan
shall be 1,132,813 and shall consist of authorized but unissued shares or
treasury shares of Stock or any combination thereof. Shares of Stock underlying

Plan.

         4.2 ADJUSTMENTS.

            (a) Stock Splits, Stock Dividends, Etc. If the Company at any time
increases or decreases the number of its outstanding shares of Stock, or changes
in any way the rights and privileges of such shares, by means of the payment of
a stock dividend or the making of any other distribution upon such shares
payable in Stock, or through a stock split or subdivision of shares, or a
consolidation or combination of shares, or through a reclassification or
recapitalization involving the Stock, then the class, numbers, rights and
privileges of the following shall be increased, decreased or changed in like
manner as if the Stock issuable upon exercise of the Option had been validly
issued and outstanding, fully paid and nonassessable at the time of such
occurrence: (i) the number and class of shares issuable pursuant to the Plan as
provided in Section 4.1, (ii) the number and class of shares for which Options
may be granted under the Plan pursuant to Section 3.2, (iii) the number and
class of shares then subject to each outstanding Option granted under the Plan,
and (iv) the Option Price for each outstanding Option.

         If a majority of the shares which are of the same class as the shares
that are subject to outstanding Options are exchanged for, converted into, or
otherwise become (whether or not pursuant to a Transfer of Control (as defined
in Section 5.1) shares of another corporation (the "New Shares"), the Board may
unilaterally amend the outstanding Options to provide that such Options are
exercisable for New Shares. In the event of any such amendment, the number of
shares subject to, and the Option Price of, the outstanding Options shall be
adjusted in a fair and equitable manner as determined by the Board, in its sole
discretion.

Company shall at any time distribute with respect to its outstanding Stock,
assets or securities of other persons (excluding cash dividends, distributions
payable out of capital surplus, and dividends or other distributions referred to
in Sections 4.2(a) and (c)), then the Option Price of outstanding Options shall
be adjusted to reflect the fair market value of the assets or securities
distributed, the Company shall provide for the delivery upon exercise of such
Options of cash in an amount equal to the appropriate portion of the fair market
value of the assets or securities distributed, or a combination of such actions
shall be taken, all as determined by the Company in its discretion. Fair market
value of the assets or securities distributed for this purpose shall be as
determined by the Company.

            (c) Distributions of Capital Stock and Indebtedness. If the Company
at any time distributes to all holders of Stock shares of its capital stock
(other than Stock), or evidences of its

                                                                             -7-
<PAGE>

indebtedness, then a proportionate part of such capital stock and evidences of
indebtedness shall be set aside for each outstanding Option and, upon exercise
of the Option, delivered to the Holder of such Option.

         4.3 NO RIGHTS AS STOCKHOLDER. A Holder shall have none of the rights of
a stockholder with respect to the shares subject to an Option until such shares
are transferred to the Holder upon exercise of such Option. Except as provided
in Section 4.2, no adjustments shall be made for dividends, rights or other
property distributed to stockholders (whether ordinary or extraordinary) for
which the record date is prior to the date such shares are so transferred.

         4.4 FRACTIONAL SHARES. No adjustments or substitution provided for in
this Article IV shall require the Company to sell a fractional share. The total
substitution or adjustment with respect to each Option shall be limited by
deleting any fractional share. In no event may the Option Price of any Option be
decreased to an amount less than the par value, if any, of the stock subject to
the Option.

wherein the stockholders of the Company immediately before such sale or exchange

indirectly (including without limitation, through their ownership of shares of
the voting stock of a corporation which, as a result of such sale or exchange,
owns the Company either directly or through one or more subsidiaries), at least
a majority of the beneficial interest in the voting stock of the Company's
immediately after such sale or exchange;

            (b) a merger or consolidation wherein the stockholders of the
Company immediately before such merger or consolidation do not retain in
substantially the same proportions as their ownership of shares of the Company's
voting stock immediately before such event, directly or indirectly (including,

corporation which, as a result of such merger or consolidation, owns the Company
either directly or through one or more subsidiaries), at least a majority of the
beneficial interest in the voting stock of the Company immediately after such

                                                                             -8-

Corporation(s) immediately after such event); or

            (d) a liquidation or dissolution of the Company.

         5.2 EFFECT ON OPTIONS. In the event of a Transfer of Control, any
unexercisable or unvested portion of the outstanding Options shall be
immediately exercisable and vested in full as of the date ten (10) days prior to
the date of the Transfer of Control, and the Company shall provide each Holder
of an outstanding Option with at least ten (10) days advance written notice of
the pending Transfer of Control prior to the consummation thereof. The exercise
or vesting of any Option that was permissible solely by reason of this Section
5.2 shall be conditioned upon the consummation of the Transfer of Control. In
addition, the Board, in its sole discretion, may arrange with the surviving,
continuing, successor, or purchasing corporation or parent corporation thereof,
as the case may be (the "Acquiring Corporation"), for the Acquiring Corporation
to either assume the Company's rights and obligations under outstanding Options
or substitute substantially equivalent options for the Acquiring Corporation's

as otherwise provided in such Option Agreement. If the corporation the stock of
which is subject to the outstanding Options immediately prior to a Transfer of
Control described in Section 8.1(a) is the surviving or continuing corporation,
the outstanding Options shall be deemed to have been assumed by the Acquiring
Corporation for purposes of this Section 5.2.
