<PAGE>

administration of the Amended Director Plan.  Notwithstanding the foregoing, 
the Company shall have no authority or discretion as to the persons eligible 
to receive Options under the Amended Director Plan, or the number of Shares 
covered by Options under the Amended Director Plan, which matters are 
specifically governed by the provisions of this Amended Director Plan.

     4.   RESTRICTIONS.

     All Options granted under the Amended Director Plan shall be subject to
the requirement that, if at any time the Company shall determine, in its
discretion, that the listing, registration or qualification of the Shares
subject to Options granted under the Amended Director Plan upon any securities
exchange or under any state or federal law, or the consent or approval of any
government regulatory body, is necessary or desirable as a condition of, or in
connection with, the granting of such Option or the issuance, if any, or
purchase of Shares in connection therewith, such Option may not be exercised in
whole or in part unless such listing, registration, qualification, consent or
approval shall have been effected or obtained free of any conditions not
acceptable to the Company.

     5.   SHARES SUBJECT TO AMENDED DIRECTOR PLAN.

          (a)  AGGREGATE NUMBER.  Subject to adjustment in accordance with
Section 7(g), a total of   187,500 Shares are reserved for issuance under this
Amended Director Plan.  Shares sold under this Amended Director Plan may be
unissued Shares or reacquired Shares.  If any Options shall for any reason be
canceled, terminate or expire without having been exercised in full, Shares not
purchased thereunder shall be available again for grant under this Amended
Director Plan.

          (b)  RIGHTS AS STOCKHOLDER.  No Eligible Director and no beneficiary
or other person claiming under or through such Eligible Director shall have any
rights as a stockholder with respect to Shares acquired by exercise of an
Option until the issuance (as evidenced by the appropriate entry on the books
of the Company or a duly authorized transfer agent) of a stock certificate
evidencing the Shares.  Subject to Section 7(g), no adjustment shall be made
for dividends or other events for which the record date is prior to the date
the certificate is issued.

          (c)  RIGHTS WITH RESPECT TO SHARES.  No Eligible Director and no
beneficiary or other person claiming under or through such Eligible Director
shall have any right, title or interest in or to any Shares subject to any
Option unless and until such Option is duly exercised pursuant to the terms of
this Amended Director Plan.

     6.   NONDISCRETIONARY GRANTS

     Stock options for 2,250 shares each will continue to be automatically
granted to the Non-employee Directors,  from the Amended Director Plan, at each
annual meeting after stockholder approval.

                                       3


<PAGE>

          (a)  INITIAL GRANT.  On the Initial Grant Date, each Eligible
Director shall automatically receive the grant of an Option to purchase 2,250
Shares.

          (b)  REGULAR ANNUAL GRANTS.  On each Annual Grant Date, immediately
after the annual election of directors, each Eligible Director then in office
shall automatically receive the grant of an Option to purchase 2,250 Shares.

          (c)  ADJUSTMENT.  The number of Shares for which Options are granted
in accordance with this Section 6 and the number of Shares subject to any
Option shall be subject to adjustment in accordance with Section 7(g).

     7.   TERMS OF OPTION AGREEMENTS.

     Upon the grant of each Option, the Company and the Eligible Director shall
enter into an Option Agreement which shall specify the Grant Date, the number
of Shares to which the option pertains, the exercise price per share, and shall
include or incorporate by reference the substance of all of the following
provisions and such other provisions consistent with this Amended Director Plan
as the Board may determine:

          (a)  OPTION TERM.  Unless terminated earlier pursuant to the
provisions of Sections 7(f) or 7(h), each Option shall expire and no longer be
exercisable on a date which is ten (10) years after the Grant Date of such
Option.

          (b)  EXERCISE SCHEDULE.  The Option shall be exercisable on the
earlier of the first anniversary of the Grant Date or the day immediately prior
to the date on which the stockholders have their annual meeting following the
Grant Date of the Option, providing that the Eligible Director is still serving
as a director of the Company at such time.  Notwithstanding the foregoing, an
Option held by an Eligible Director shall become immediately exercisable in
full upon the death or disability of such Eligible Director, upon retirement
after age sixty-five (65) of such Eligible Director from the Board, upon an
unsuccessful attempt by such Eligible Director to win reelection to the Board,
or upon a Change of Control of the Company.

          (c)  PURCHASE PRICE.  The purchase price of the Shares subject to
each Option shall be the Fair Market Value of Shares on the Grant Date of such
Option, or on the last preceding Business Day if such Grant Date is not a
Business Day.

          (d)  PAYMENT OF PURCHASE PRICE.  The purchase price of Shares
acquired pursuant to an Option shall be paid in full at the time the Option is
exercised:  (1) in cash or cash equivalents; (2) by delivery of shares of
Common Stock of the Company, valued at the Fair Market Value on the date of
exercise; provided, however, that Options may not be exercised by the delivery
of Common Stock more frequently than at six-month intervals or (3) by delivery
of a properly executed exercise notice together with such other documentation
as the Board and the broker, if applicable, shall require to effect an 

                                       4


<PAGE>

exercise of the option and delivery to the Company of the sale proceeds 
required to pay the exercise price.

          (e)  TRANSFERABILITY.  Options are subject to limited transferability
by the original option holder and subject to approval of the Compensation
Committee of the Board of Directors.  The transfer by an Eligible Director to a
trust created by the Eligible Director for the benefit of the Eligible Director
or the Eligible Director's family which is revocable at any and all times
during the Eligible Director's lifetime by the Eligible Director and as to
which the Eligible Director is the sole trustee during his or her lifetime,
will not be deemed to be a transfer for purposes of the Amended Director Plan.
Under such rules and regulations as the Board may establish pursuant to the
terms of the Amended Director Plan, a beneficiary may be designated with
respect to an Option grant in the event of the death of an Eligible Director.
If the estate of the Eligible Director is the beneficiary with respect to the
grant, any rights with respect to such grant may be transferred to the person
or entity (including a trust) entitled thereto under the will of such Eligible
Director or pursuant to the laws of descent and distribution.

          (f)  TERMINATION OF MEMBERSHIP ON THE BOARD.  If an Eligible
Director's membership on the Board terminates for any reason, an Option held at
the date of termination may be exercised in whole or in part at any time within
the remaining term of the Option but only to the extent exercisable in
accordance with Section 7(b).

          (g)  CAPITALIZATION CHANGES.  If any change is made in the Shares
subject to the Amended Director Plan or subject to any Option granted under the
Amended Director Plan, through merger, consolidation, reorganization,
recapitalization, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure, or any other capital reorganization, the Board shall
make appropriate adjustments as to the maximum number of Shares subject to the
Amended Director Plan, the number of Shares for which Options may be granted to
any Eligible Director, and the number of Shares and price per Share covered by
outstanding Options.

          (h)  CHANGE OF OWNERSHIP.  In the event of (i) a dissolution or
liquidation of the Company or (ii) a merger or consolidation in which the
Company is not the surviving corporation, the Company shall give to the
Eligible Director, at the time of adoption of the plan for liquidation,
dissolution, merger or consolidation, either:  a reasonable time thereafter
within which to exercise the Option, prior to the effectiveness of such
liquidation, dissolution, merger or consolidation, at the end of which time the
Option shall terminate; or the right to exercise the Option as to an equivalent
number of shares of stock of the corporation succeeding the Company or
acquiring its business by reason of such liquidation, dissolution, merger or
consolidation.

          (i)  WITHHOLDING TAXES.  Whenever Shares are to be issued under the
Amended Director Plan, the Company shall have the right to require payment to
the Company by the person to receive such Shares of an amount sufficient to
satisfy federal, 

                                       5


<PAGE>

state and local withholding tax requirements prior to delivery of any 
certificate or certificates representing such Shares.  Payment of withholding 
taxes may be made by delivery of Company stock or options to the Company.

     8.   USE OF PROCEEDS.

     Proceeds from the sale of Shares pursuant to this Amended Director Plan
shall be used by the Company for general corporate purposes.


     9.   LEGAL REQUIREMENTS.

     Shares shall not be offered or issued under this Amended Director Plan
unless the offer, issuance and delivery of such Shares shall comply with all
applicable provisions of law, domestic or foreign, including, without
limitation, the Securities Act of 1933, as amended, and the requirements of any
stock exchange upon which the Shares may then be listed.  As a condition
precedent to the issuance of Shares pursuant to a grant under this Amended
Director Plan, the Company may require an Eligible Director to take any
reasonable action to comply with such requirements.  Any certificates
representing Shares purchased upon exercise of an Option shall bear appropriate
legends.

     10.  AMENDMENT AND INTERPRETATION OF AMENDED DIRECTOR PLAN.

          (a)  STOCKHOLDER APPROVAL REQUIRED.  The Board may amend the Amended
Director Plan at any time.  No amendment adopted without stockholder approval
may (i) increase the number of shares as to which Options may be granted,
(ii) reduce the exercise price below the price provided in the Amended Director
Plan, (iii) modify the requirements as to eligibility for participation, or
(iv) materially increase the benefits accruing under the Amended Director Plan.

          (b)  PROHIBITED AMENDMENTS.  No amendment shall (i) change the
nondiscretionary manner in which grants are made under Section 6, or
(ii) affect the rights of the holder of any Option, except with that holder's
consent.

          (c)  INTERPRETATION.  Questions of interpretation of any of the
provisions of the Amended Director Plan shall be resolved by legal counsel for
the Company selected by the Chief Executive Officer of the Company.

     11.  TERMINATION OR SUSPENSION OF AMENDED DIRECTOR PLAN.

     The Board at any time may suspend or terminate this Amended Director Plan.
This Amended Director Plan, unless sooner terminated, shall terminate on 
February 19, 2008.  No Option may be granted under this Amended Director Plan 
while this Amended Director Plan is suspended or after it is terminated. 
Suspension or 

                                       6

termination of this Amended Director Plan shall not affect the rights of the

     12.  EFFECTIVE DATE; STOCKHOLDER APPROVAL.

     This Amended Director Plan has been approved by the Board and shall become
effective on May 7, 1998, subject to its approval by the stockholders of the
Company.  The remaining shares in the Director Plan shall be granted, prior to
Options being issued from the Amended Director Plan.  If the stockholders fail
to approve this Amended Director Plan, within the required twelve (12) month
time period, any Options granted under this Amended Director Plan shall be
void, and no additional Options shall be granted.

     13.  DIRECTOR STATUS.

     Nothing in this Amended Director Plan or in any instrument executed
pursuant hereto shall confer upon any Eligible Director any right to continue
as a member of the Board of the Company or any parent or subsidiary thereof.

     14.  OTHER PLANS.

     Nothing in this Amended Director Plan is intended to be a substitute for,
or shall preclude or limit the establishment or continuation of, any other
plan, practice or arrangement for the payment of compensation or benefits to
directors generally, which the Company now has or may hereafter lawfully put
into effect, including, without limitation, any retirement, pension, insurance,
stock purchase, incentive compensation or bonus plan.

interest.
