                                      II-2


      Item 6.  Indemnification of Directors and Officers.

      Section 722 of the New York Business Corporation Law ("NYBCL") provides
that a corporation may indemnify any person made, or threatened to be made, a
party to any action or proceeding except for stockholder derivative suits by
reason of the fact that he or she was a director or officer of the corporation,
provided such director or officer acted in good faith for a purpose which he or
she reasonably believed to be in the best interests of the corporation and, in
criminal proceedings, had no reasonable cause to believe his or her conduct was
unlawful. In the case of stockholder derivative suits, the corporation may
indemnify any person who was a director or officer of the corporation if he or
she acted in good faith for a purpose which he or she reasonably believed to be
in the best interests of the corporation, except that no indemnification may be
made for (i) a threatened action or a pending action which is settled or
otherwise disposed of, or (ii) any claim, issue or matter as to which such
person has been adjudged to be liable to the corporation, unless and only to the
extent that the court in which the action was brought or, if no action was
brought, any court of competent jurisdiction, determines upon application that,
in view of all circumstances, the person is fairly and reasonably entitled to
indemnification for such portion of the settlement amount and expenses as the
court deems proper.

      Section 721 of the NYBCL provides that indemnification under the NYBCL is
not exclusive of other indemnification rights to which a director or officer may
be entitled, whether contained in the certificate of incorporation or bylaws,
or, when authorized by such certificate of incorporation or bylaws, (i) a
resolution of stockholders or directors, or (ii) an agreement providing for such
indemnification, provided that no indemnification may be made to or on behalf of
any director or officer if a judgment or other final adjudication adverse to the
director or officer establishes that his or her acts were committed in bad faith
or were the result of active and deliberate dishonesty and were material to the
cause of action so adjudicated, or that he or she personally gained a financial
profit or other advantage to which he or she was not legally entitled.

      Under Section 723 of the NYBCL, any person to whom such provisions in the
NYBCL regarding indemnification apply who has been successful on the merits or
otherwise in the defense of a civil or criminal action or proceeding is entitled
to indemnification. Except as provided in the preceding sentence, unless ordered
by a court pursuant to the NYBCL, indemnification under the NYBCL, the
certificate of incorporation, the bylaws, any resolution of stockholders or
directors or any agreement pursuant to the above paragraphs may be made only if
authorized in the specific case and after a finding that the director or officer
met the requisite standard of conduct (i) by the board acting by a quorum of
disinterested directors, or (ii) if such quorum is not available, or even if
available, if so directed by a quorum of disinterested directors by either (A)
the board upon the written opinion of counsel, or (B) by the stockholders.


                                      II-3


      First Empire's Certificate of Incorporation provides that First Empire
will indemnify to the maximum extent permissible under New York law its officers
and directors for liability arising out of their actions in such capacity. First
Empire has purchased directors' and officers' liability insurance covering
certain liabilities which may be incurred by the officers and directors of First
Empire in connection with the performance of their duties.

      Item 7.  Exemption from Registration Claimed.

      Not applicable.

      Item 8.  Exhibits.

      The exhibits listed on the Exhibit Index on page II-9 of this
Post-Effective Amendment No. 1 on Form S-8 to Registration Statement on Form S-4
have been previously filed, are filed herewith or are incorporated herein by
reference to other filings.

      Item 9.  Undertakings.

      First Empire hereby undertakes:

      1.    To file, during any period in which offers or sales are being made,
            a post-effective amendment to the Registration Statement:

            (a)   To include any prospectus required by Section 10(a)(3) of the
                  Securities Act of 1933, as amended (the "Securities Act");

            (b)   To reflect in the prospectus any facts or events arising after
                  the effective date of the Registration Statement (or the most
                  recent post-effective amendment thereof) which, individually
                  or in the aggregate, represent a fundamental change in the
                  information set forth in the Registration Statement.
                  Notwithstanding the foregoing, any increase or decrease in
                  volume of securities offered (if the total dollar value of
                  securities offered would not exceed that which was registered)
                  and any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of
                  prospectus filed with the Commission pursuant to Rule 424(b)
                  if, in the aggregate, the changes in volume and price
                  represent no more than a 20% change in the maximum aggregate
                  offering price set forth in the "Calculation of Registration
                  Fee" table in the effective Registration Statement;


                                      II-4


            (c)   To include any material information with respect to the plan
                  of distribution not previously disclosed in the Registration
                  Statement or any material change to such information in the
                  Registration Statement.

            Provided, however, that the undertakings set forth in paragraphs
            1(a) and 1(b) above do not apply if the information required to be
            included in a post-effective amendment by those paragraphs is
            contained in periodic reports filed by First Empire pursuant to
            Section 13 or 15(d) of the Exchange Act, which are incorporated by
            reference in this Registration Statement.

      2.    That, for the purpose of determining any liability under the
            Securities Act, each such post-effective amendment shall be deemed
            to be a new registration statement relating to the securities
            offered therein, and the offering of such securities at that time
            shall be deemed to be the initial bona fide offering thereof.

      3.    To remove from registration by means of a post-effective amendment
            any of the securities being registered which remain unsold at the
            termination of the offering.

      4.    That, for purposes of determining any liability under the Securities
            Act, each filing of First Empire's annual report pursuant to Section
            13(a) or Section 15(d) of the Exchange Act that is incorporated by
            reference in the Registration Statement shall be deemed to be a new
            registration statement relating to the securities offered therein,
            and the offering of such securities at that time shall be deemed to
            be the initial bona fide offering thereof.

      5.    Insofar as indemnification for liabilities arising under the
            Securities Act may be permitted to directors, officers and
            controlling persons of First Empire pursuant to the foregoing
            provisions, or otherwise, First Empire has been advised that in the
            opinion of the Commission such indemnification is against public
            policy as expressed in the Securities Act and is, therefore,
            unenforceable. In the event that a claim for indemnification against
            such liabilities (other than the payment by First Empire of expenses
            incurred or paid by a director, officer or controlling person of
            First Empire in the successful defense of any action, suit or
            proceeding) is asserted by such director, officer or controlling
            person in connection with the securities being registered, First
            Empire will, unless in the opinion of its counsel the matter has
            been settled by controlling precedent, submit to a court of
            appropriate jurisdiction the question whether such indemnification
            by it is against public policy as expressed in the Securities Act
            and will be governed by the final adjudication of such issue.


                                      II-5


                                   SIGNATURES

      Pursuant to the requirements of the Securities Act of 1933, First Empire
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Post-Effective
Amendment No. 1 on Form S-8 to Registration Statement on Form S-4 to be signed
on its behalf by the undersigned, thereunto duly authorized, in the City of
Buffalo, State of New York, on May 18, 1998.

secure for the Company and its stockholders the benefits of the incentive
inherent in increased common stock ownership of non-employee Directors of the

Company that will increase their proprietary interest in the Company's success
and progress and their identification with the interests of the Company's
stockholders.

3.  Administration

      The Plan shall be administered by the Compensation and Stock Option
Committee. The Committee shall have the powers vested in it by the terms of the
Plan, such powers to include authority (within the limitations described herein)
to prescribe the form of the agreement embodying awards of Options made under
the Plan. The Committee shall, subject to the provisions of the Plan, grant
Options under the Plan and shall have the power to construe the Plan, to
determine all questions arising thereunder and to adopt and amend such rules and
regulations for the administration of the Plan as it may deem desirable. Any
decision of the Committee in the administration of the Plan, as described
herein, shall be final and conclusive. The Committee may act only by a majority
of its members in office, except that the members thereof may authorize any one
or more of their number or the Treasurer or any other officer of the Company to
execute and deliver documents on behalf of the Committee. No member of the
Committee shall be liable for anything done or omitted to be done by such member
or by any other member of the Committee in connection with the Plan, except for
such member's own willful misconduct or as expressly provided by statute.

4.  Amount of Shares

      The Shares which may be issued and sold under the Plan will be the Common
Stock (par value $1.00 per share) of the Company, of a total number not
exceeding 100,000 shares, subject to adjustment as provided in Paragraph 8(c)
below. The stock to be issued may be either authorized and unissued shares or

the Plan shall terminate or expire without being exercised in whole or in part,
new Options may be granted covering the Shares not purchased under such lapsed
Options.

5.  Eligibility

      Each member of the Board of the Company who is not an employee of the
Company or any of its subsidiaries (a "Non-Employee Director") shall be eligible
to receive an Option in accordance with Paragraph 6 below. The adoption of this
Plan shall be not deemed to give any director any right to be granted an option
to purchase Common Stock of the Company, other than in accordance with the terms
of this Plan.


                                     - 3 -


6.  Terms and Conditions of Options

      Each Option granted under the Plan shall be evidenced by an agreement in
such form as the Board shall prescribe from time to time in accordance with the
Plan and shall comply with the following terms and conditions:

      (a)   The Option Exercise Price shall be the Fair Market Value of the
            Shares subject to such Option on the date the Option is granted.

      (b)   Each year, as of the date of the Annual Meeting of Stockholders of
            the Company, each Non-Employee Director who has been elected or
            re-elected or who is continuing as a member of the Board as of the
            adjournment of the Annual Meeting and who has not previously been
            granted Options pursuant to this Plan shall automatically receive an
            Option for 3,000 Shares.

      (c)   Subject to the limitations of the Plan and the Option  Agreement,
            an Option  holder  may,  at any time  during  the  Option  Period,
            exercise  his/her  right to purchase all or any part of the Shares
            to which the Option relates;  provided,  however, that the minimum
            number of Shares which may be purchased  shall be twenty (20), or,
            if less,  the total number of Shares  relating to the Option which
            are then  available for purchase and the maximum  number of Shares
            which may be  purchased  shall be  limited by  Paragraph 7(b).  An
            Option holder shall exercise an Option to purchase Shares by:

            (i)   giving written notice to the Committee or its designate, in
                  such form and manner as the Committee may prescribe, of
                  his/her intent to exercise the Option;

            (ii)  delivering to the Committee or its designate full payment for
                  the Shares as to which the Option is to be exercised; and

            (iii) satisfying such other conditions as may be prescribed in the
                  Option Agreement.

Payment shall be made (1) in United States dollars in cash or by certified
check, money order or bank draft drawn payable to the order of ONBANCorp, Inc.,
or (2) by delivering a certificate or certificates evidencing the Option
holder's ownership in Shares valued at their Fair Market Value, or (3) through
the withholding of Shares issuable upon exercise of the Option valued at their
Fair Market Value on the date of exercise or (4) by a combination of the methods
set forth in (1), (2) and (3). ONBANCorp may also enter into any arrangement
permitted under applicable laws (including Section 16(c) of the Securities
Exchange Act of 1934) to permit the "cashless" exercise of any Option.


                                     - 4 -


      (d)   When the requirements of Paragraph 6(c) have been satisfied, the
            Committee or its designate shall take such action as is necessary to
            cause ONBANCorp to issue a Certificate evidencing the Option
            holder's ownership of such Shares. The person exercising the Option
            shall have no right to vote or to receive dividends, nor have any
            other rights with respect to the Shares, prior to the date as of
            which such Shares are transferred to such person on the stock
            transfer records of ONBANCorp, and no adjustments shall be made for
            any dividends or other rights for which the record date is prior to
            the date as of which such transfer is effected, except as may be
            required under Paragraph 8(c).

      (e)   Shares acquired in connection with the exercise of an Option shall
            not be assignable or transferable, other than by will or by the laws
            of descent and distribution, during any period which would cause
            such sale to be in violation of Section 16(b) of the Securities
            Exchange Act of 1934.

      (f)   An Option by its terms shall not be assignable or transferable by
            the Option holder other than by will or by the laws of descent and
            distribution, and shall be exercisable, during the lifetime of the
            Option holder, only by the Option holder or his/her legally
            appointed guardian.

      (g)   The Company's obligation to deliver Shares with respect to an Option
            shall, if the Committee so requests, be conditioned upon the receipt
            of a representation as to the investment intention of the Option
            holder to whom such Shares are to be delivered, in such form as the
            Committee shall determine to be necessary or advisable to comply
            with the provisions of applicable Federal, state or local law. It
            may be provided that any such representation shall become
            inoperative upon a registration of the Shares or upon the occurrence
            of any other event eliminating the necessity of such representation.
            The Company shall not be required to deliver any Shares under the
            Plan prior to (i) the admission of such Shares to listing on any
            stock exchange on which Shares may then be listed, or (ii) the
            completion of such registration or other qualification under any
            state or Federal law, rule or regulation as the Committee shall
            determine to be necessary or advisable.

7.  Option Period

      (a)   The Option Period during which any portion of an Option may be
            exercised shall commence one year after the date on which the Option
            is granted and shall expire on the earlier of:

            (i)   The last day of the one-year period commencing on the date of
                  the Option holder's Retirement, death or Disability; or


                                     - 5 -


            (ii)  The last day of the ten-year period commencing on the date on
                  which the Option was first exercisable.

      (b)   The Option shall become exercisable with respect to one-third
            (33-1/3%) of the total number of shares to the nearest whole Share
            of Common Stock covered by the Option beginning one year after the
            date on which the Option is granted; thereafter it shall become
            exercisable with respect to an additional one-third (33-1/3%) of the
            total number of shares to the nearest whole Share of Common Stock
            covered by the Option on each subsequent anniversary date of the
            grant of the Option until on the third anniversary date of the grant
            of the Option it shall become exercisable with respect to the total
            number of shares of Common Stock covered by the Option. In the event
            the Non-Employee Director ceases to be a Non-Employee Director by
            reason of Retirement, death or Disability, all Options then held by
            such individual under this Plan shall then become immediately
            exercisable and shall expire as set forth in Paragraph 7(a).

8.  Amendments and Termination

      (a)   Termination. Subject to Paragraph 8(d), the Board of Directors may
            suspend or terminate the Plan in whole or in part at any time prior
            to April 30, 2002 by giving written notice of such suspension or
            termination to the Committee. Unless sooner terminated, the Plan
            shall terminate automatically on April 30, 2002.

      (b)   Amendment. Subject to Paragraph 8(d), the Board of Directors may
            amend or revise the Plan in whole or in part at any time; provided,
            however, that it shall not be amended more than once every six (6)
            months other than to comply with the Internal Revenue Code of 1986,
            as amended, or the Employee Retirement Income Security Act of 1974,
            as amended, or the rules and regulations promulgated under such
            laws, and further provided that, subject to Paragraph 8(c), the
            following amendments or revisions shall be subject to approval by
            the holders of at least a majority of the outstanding voting stock
            of ONBANCorp:

            (i)   an increase of more than ten percent (10%) in the number of
                  Shares as to which Options may be granted;

            (ii)  a decrease in the Exercise Price for an Option previously
                  granted;

            (iii) an extension of the term of the Plan or an extension of the
                  Option Period beyond the last day of the ten-year period
                  commencing on the date on which the Option was fully
                  exercisable for an Option previously granted;


                                     - 6 -


            (iv)  any other amendment which would materially increase the
                  benefits accruing to participants in the Plan within the
                  meaning of Section 16b-3 of the Securities Exchange Act of
                  1934; and

            (v)   any change which requires an amendment of ONBANCorp's
                  certificate of organization.

      (c)   Adjustments in the Event of Reorganization or Recapitalization.

            (i)   in the event of any merger, consolidation, or other business
                  reorganization in which ONBANCorp is the surviving entity, and
                  in the event of any stock split, stock dividend or other event
                  generally affecting the Shares held by each person who is then
                  a holder of record of Shares, the Committee shall determine
                  the appropriate adjustments, if any, to the maximum number of
                  Shares with respect to which Options may be granted under the
                  Plan, the number of Shares as to which Options have been
                  granted under the Plan, and the Exercise Price therefor, if
                  applicable, to preserve but not to increase the benefits under
                  the Plan.

            (ii)  in the event of any merger, consolidation, or other business
                  reorganization in which ONBANCorp is not the surviving entity:

                  (1)   any Options granted under the Plan which remain
                        outstanding may be cancelled by the Board upon written
                        notice to each Option holder given at least 30 days in
                        advance of the effective date of such merger,
                        consolidation, business reorganization, liquidation or
                        sale; and

                  (2)   any Options which are not cancelled pursuant to
                        Paragraph 8(c)(ii)(1) shall be adjusted in such manner
                        as the Committee shall deem appropriate to account for
                        such merger, consolidation or other business
                        reorganization.

      (d)   Consent of Grantee. No amendment, suspension or termination of the
            Plan shall be made that would materially adversely affect any grant
            previously made under the Plan without the prior written consent of
            the grantee.

9.  Miscellaneous Provisions

      (a)   No Right to Continued Directorship. Neither the establishment of the
            Plan nor any provisions of the Plan nor any action of the Board of
            Directors or the Committee with respect to the Plan shall be held or
            construed to confer upon any 


                                     - 7 -

      (b)   Construction of Language. Whenever appropriate in the Plan, words
            used in the singular may be read in the plural, words used in the
            plural may be read in the singular, and words importing the
            masculine gender may read as referring equally to the feminine or
            the neuter. Any reference to an article or section number shall
            refer to an article or section of this Plan, unless otherwise
            indicated.

      (c)   Governing Law. The Plan shall be constructed and enforced in
            accordance with the laws of the State of Delaware, except to the

            United States of America.

      (d)   Headings. The headings of articles and sections are included solely
            for convenience of reference. If there is any conflict between such
            headings and the text of the Plan, the text shall control.

      (e)   Non-Alienation of Benefits. The right to receive a benefit under the
            Plan shall not be subject in any manner to anticipation, alienation
            or assignment, nor shall such right be liable for or subject to
            debts, contracts, liabilities, engagements or torts.

      (f)   Taxes. Where any Person is entitled to receive Shares pursuant to
            the exercise of an Option, the Corporation shall have the right to
            require such person to pay the Corporation the amount of any tax
            which the Corporation is required to withhold with respect to such
            Shares, or, in lieu thereof, to retain, or to sell without notice, a
            sufficient number of Shares to cover the amount required to be
            withheld.

      (g)   Notices. Any notice required or permitted to be given to a party
            under the Plan shall be deemed given if personally delivered or if
            mailed, postage pre-paid, by certified mail, return receipt to
            requested, to the party at the address listed below, or at such
            other address as one such party may by written notice specify to the

employees and non-employee members of the Board to enter into or remain in the
employ of the Company or any Affiliate or to serve on the Board and to devote
themselves to the Company's success and to reward past service of such persons
by providing them with an opportunity to acquire or increase a proprietary

      3. Administration. The Plan shall be administered by the Committee.

            (a) Meetings. The Committee shall hold meetings at such times and

grant Awards and Options pursuant to the terms of the Plan. Subject to Section

conditions thereof, including in the case of an Option a specification with
respect 


                                     - 2 -


to whether or not the Option is intended to be an ISO and/or to include an SAR.
In making such determinations the Committee may take into account the nature of
the person's services and responsibilities, the person's present and potential
contribution to the Company's success and such other factors as it may deem
relevant. The interpretation and construction by the Committee of any provision
of the Plan or of any Award or Option granted under it shall be final, binding
and conclusive.

            (c) Exculpation. Each member of the Committee shall be exculpated

their services on the Board pursuant to any applicable provision of law or the
terms of the Company's Articles of Incorporation or By-laws.

            (d) Indemnification. Each member of the Board or of the Committee
shall be entitled without further act on his part to indemnity from the Company
to the fullest extent provided by applicable law and the Company's Articles of
Incorporation or By-laws in connection with or arising out of any action, suit
or proceeding with respect to the administration of the Plan or the granting of
Awards or Options under it in which he may be involved by reason of his being or
having been a member of the Board or the Committee, whether or not he continues
to be such member of the Board or the Committee at the time of the action, suit
or proceeding.

      4. Eligibility.

            (a) Key Employees. All key employees of the Company or an Affiliate

effective under subsection 6(a), each person then serving on the Board who is
not an employee of the Company or an Affiliate shall be granted an Option to
purchase 5,000 shares of Common Stock at an exercise price equal to the initial
offering price of the Common Stock. Except as provided in this subsection, no
non-employee director of the Company or an Affiliate on the date this Plan
becomes effective shall be eligible to be granted Options or Awards under this
Plan.

            (c) Future Outside Directors. Each person who begins his initial
service on the Board after the date this Plan becomes effective shall be
eligible to receive Options but not Awards hereunder; however, any Option shall
not be an ISO unless such person is also an employee of the Company or an
Affiliate. The Committee shall specify at the time of grant of an Option whether
such Option includes a SAR.


                                     - 3 -


      5. Shares. The aggregate maximum number of shares of the Common Stock for
which Awards or Options may be issued under the Plan is 517,500 shares, adjusted
as provided in Section 11. Shares shall be issued from authorized and unissued
Common Stock or Common Stock held in or hereafter acquired for the treasury of
the Company. If any outstanding Option granted under the Plan expires, lapses or
is terminated for any reason or if any shares which are subject to an Award are
forfeited for any reason, the Shares allocable thereto may again be the subject
of an Award or Option granted pursuant to the Plan.

      6. Effective Date and Term of the Plan.

            (a) Effective Date. The Plan shall be effective as of the date of
the commencement of the Company's initial underwritten public offering of its
Common Stock. If the Plan is not approved within one year after such effective
date by a majority of the outstanding voting stock of the Company voting either
in person or by proxy, at a duly called meeting of the shareholders, then no
Option granted pursuant to the Plan shall be an ISO and all ISOs previously
granted under the Plan shall remain outstanding but shall not be treated as
ISOs.

            (b) Term. This Plan shall terminate on May 18, 1998, and no Option
or Award shall be granted hereunder after May 18, 1998.

      7. Terms and Conditions of Options. Options granted pursuant to the Plan
shall be evidenced by written Option Agreements in such form as the Committee
shall from time to time approve, which Option Agreements shall comply with and
be subject to the following terms and conditions and such other terms and
conditions which the Committee shall from time to time require which are not
inconsistent with the terms of the Plan.

            (a) Number of Shares. Each Option Agreement shall state the number
of shares to which it pertains.

            (b) Exercise Price. Each Option Agreement shall state the exercise
price at which shares covered by the Option may be purchased. In the case of an
ISO, the exercise price shall be at least 100% of the fair market value of the
Common Stock on the date the ISO is granted and, in the case of an Option that
is not an ISO, the exercise price shall be at least 85% of the fair market value
of the Common Stock on the date such Option is granted, as fair market value
determined by the Committee; provided, however, if an ISO is granted to an
Optionee who then owns, directly or by attribution under section 425(d) of the
Code, shares possessing more than ten percent of the total combined voting power
of all classes of stock of the Company or an Affiliate, then the exercise price
shall be at least 110% of the fair market value of the shares on the date the
Option is granted. If the Common Stock is traded in a public market, then the
fair market value per share shall be the mean between the closing "bid" and
"asked" prices thereof or the mean between the highest and lowest quoted selling
prices thereof, 


                                     - 4 -


as applicable, as the Committee determines, on the day the Option is granted as
reported in customary financial reporting services.

            (c) Medium of Payment. An Optionee shall pay for shares (i) in cash,
(ii) by certified check payable to the order of the Company, or (iii) by such
other mode of payment as the Committee may approve. Furthermore, the Committee
may provide in an Option Agreement that payment may be made all or in part in
shares of the Common Stock held by the Optionee. If payment is made in whole or
in part in shares of the Common Stock, then the Optionee shall deliver to the
Company certificates registered in the name of such Optionee representing shares
of Common Stock owned by such Optionee, free of all liens, claims and
encumbrances of every kind, accompanied by stock powers duly endorsed in blank
by the Optionee. For purposes of determining the amount of payment, shares of
Common Stock tendered as payment by the Optionee shall be valued at fair market
value (as determined by the Committee under subsection 6(b)) on the date of
exercise (as determined under Section 9). Notwithstanding the foregoing, the
Committee, in its sole discretion, may refuse to accept shares of Common Stock
in payment of the exercise price. In that event, any certificates representing
shares of Common Stock which were delivered to the Company shall be returned to
the Optionee with notice of the refusal of the Committee to accept such shares
in payment of the exercise price. The Committee may impose from time to time
such limitations and prohibitions on the use of shares of the Common Stock to
exercise an Option as it deems appropriate.

            (d) Termination of Options. No Option shall be exercisable after the
first to occur of the following:

                  (i) Expiration of the term specified in the Option Agreement,
which shall not exceed (A) ten years from the date of grant, or (B) five years
from the date of grant with respect to an ISO if the Optionee on the date of
grant owns, directly or by attribution under section 425(d) of the Code, shares
possessing more than ten percent of the total combined voting power of all
classes of stock of the Company or of an Affiliate;

                  (ii) Termination of the Optionee's employment or service with
the Company and its Affiliates, subject to such additional periods not to exceed
one year as the Committee shall determine, which periods may vary with the
reason for termination including, without limitation, the Optionee's death,
disability or retirement;

                  (iii) The date set by the Committee to be an accelerated
expiration date in the event of dissolution or liquidation of the Company or
consummation of any acquisition or business combination transaction in which the
Company is not the surviving or acquiring entity or in which the Company becomes
an 80% or more owned subsidiary of another person or


                                     - 5 -


company, in which case the Committee may take whatever other action with respect
to the Option, including acceleration of any exercise provisions, it deems
necessary or desirable; or

                  (iv) A finding by the Committee, after full consideration of
the facts presented on behalf of both the Company and the Optionee, that the
Optionee has breached his employment or service contract with the Company or an
Affiliate, or has been engaged in any sort of disloyalty to the Company or an
Affiliate, including, without limitation, fraud, embezzlement, theft, commission
of a felony or proven dishonesty in the course of his employment or service or
has disclosed trade secrets or confidential information of the Company or an
Affiliate. In such event, in addition to immediate termination of the Option,
the Optionee, upon a determination by the Committee, shall automatically forfeit
all shares for which the Company has not yet delivered the share certificates
upon refund by the Company of the exercise price.

            (e) Transfers. No Option granted under the Plan may be transferred,
except by will or by the laws of descent and distribution. During the lifetime
of the person to whom an Option is granted, such Option may be exercised only by
him or his legal representative in the event of his incompetence.

            (f) Other Provisions. The Option Agreements shall contain such other
provisions including, without limitation, additional restrictions upon the
exercise of the Option or additional limitations upon the term of the Option, as
the Committee shall deem advisable.

            (g) Amendment. The Committee shall have the right to amend Option
Agreements issued to an Optionee subject to his consent, except that the consent
of the Optionee shall not be required for any amendment made under subsection
7(d)(iii).

      8. Stock Appreciation Rights (SARs).

            (a) In General. Subject to the terms and conditions of the Plan, the
Committee may, in its sole and absolute discretion, grant to an Optionee in
connection with an Option rights to surrender to the Company, in whole or in
part, an Option, and to receive in exchange therefor payment by the Company of
an amount equal to the excess of the fair market value of the shares of Common
Stock subject to such Option, or portion thereof, so surrendered (determined in
the manner described in subsection 7(b) as of the date the SARs are exercised)
over the exercise price to acquire such shares. Such payment may be made, as
determined by the Committee in accordance with subsection 8(c) below and set
forth in the Option Agreement, either in shares of Common Stock or in cash or in
any combination thereof.

            (b) Grant. Each SAR shall relate to a specific Option granted under
the Plan and shall be granted to the Optionee concurrently with the grant of
such Option by inclusion of appropriate provisions in the Option Agreement
pertaining thereto. The number of SARs granted to an


                                     - 6 -


Optionee shall not exceed the number of shares of Common Stock which such
Optionee is entitled to purchase pursuant to the related Option. The number of
SARs held by an Optionee shall be reduced by (i) the number of SARs exercised
under the provisions of the Option Agreement pertaining to the related Option,
and (ii) the number of shares of Common Stock purchased pursuant to the exercise
of the related Option.

            (c) Payment. The Committee shall have sole discretion to determine
whether, and shall set forth in the Option Agreement pertaining to the related
Option the circumstances under which, payment in respect of SARs granted to any
Optionee shall be made in shares of Common Stock, or in cash, or in a
combination thereof. If payment is made in Common Stock, the number of shares of
Common Stock which shall be issued pursuant to the exercise of SARs shall be
determined by dividing (i) the total number of SARs being exercised, multiplied
by the amount by which the fair market value (as determined under subsection
7(b)) of a share of Common Stock on the exercise date exceeds the exercise price
for shares covered by the related Option, by (ii) the fair market value of a
share of Common Stock on the exercise date of the SARs. No fractional share of
Common Stock shall be issued on exercise of an SAR; cash shall be paid by the
Company to the individual exercising an SAR in lieu of any such fractional
share. If payment on exercise of an SAR is to be made in cash, the individual
exercising the SAR shall receive in respect of each share to which exercise
relates an amount of money equal to the difference between the fair market value
of a share of Common Stock on the exercise date and the exercise price for
shares covered by the related Option.

            (d) Limitations. SARs shall be exercisable at such times and under
such terms and conditions as the Committee, in its sole and absolute discretion,
shall determine and set forth in the Option Agreements pertaining to the related
Options; provided, however, that an SAR may be exercised only at such times and
by such individuals as the related Option under the Plan and the Option
Agreement may be exercised.

      9. Exercise. No Option or SAR associated therewith shall be deemed to have
been exercised prior to the receipt by the Company of written notice of such
exercise and, in the case of an Option exercise, of payment in full of the
exercise price for the shares to be purchased. The date on which the Company
receives such notice, together with payment of the exercise price and all
information or acknowledgements required herein, shall be the exercise date of
the Option or SAR. Each such notice shall specify the number of shares to which
the exercise pertains and, in the case of an Option, shall (unless the shares
are covered by a then current registration statement or a Notification under
Regulation A under the Securities Act of 1933, as amended (the "Act")), contain
the Optionee's acknowledgment in form and substance satisfactory to the Company
that (a) such shares are being purchased for investment and not for distribution
or resale (other than a distribution or resale which, in the opinion of counsel
satisfactory to the Company, may be made without violating the registration
provisions of the Act), (b) the Optionee has been advised and understands that
(i) the shares have not been 


                                     - 7 -


registered under the Act and are "restricted securities" within the meaning of
Rule 144 under the Act and are subject to restrictions on transfer and (ii) the
Company is under no obligation to register the shares under the Act or to take
any action which would make available to the Optionee any exemption from such
registration, (c) such shares may not be transferred without compliance with all
applicable federal and state securities laws, and (d) an appropriate legend
referring to the foregoing restrictions on transfer may be endorsed on the
certificates. Notwithstanding the above, should the Company be advised by
counsel that issuance of shares should be delayed pending (A) registration under
federal or state securities laws or (B) the receipt of an opinion that an
appropriate exemption therefrom is available, the Company may defer exercise of
any Option granted hereunder until either such event in (A) or (B) has occurred.

      10. Terms and Conditions of Awards. Awards granted pursuant to the Plan
shall be evidenced by written Award Agreements in such form as the Committee
shall from time to time approve, which Award Agreements shall comply with and be
subject to the following terms and conditions and such other terms and
conditions which the Committee shall from time to time require which are not
inconsistent with the terms of the Plan.

            (a) Number of Shares. Each Award Agreement shall state the number of
shares of Common Stock to which it pertains.

            (b) Purchase Price. Each Award Agreement shall specify the purchase
price, if any, which applies to the Award. If the Board specifies a purchase
price, the Grantee shall be required to make payment on or before the date
specified in the Award Agreement, which date shall not be more than 30 days from
the date the Award is made. Grantee shall pay for shares (i) in cash, (ii) by
certified check payable to the order of the Company, or (iii) by such other mode
of payment as the Committee may approve.

            (c) Transfer. In the case of an Award which provides for a transfer
of shares without any payment by the Grantee, the transfer shall take place on
the date specified in the Award Agreement. In the case of an Award which
provides for a payment, the transfer shall take place on the date payment is
delivered to the Company. Stock certificates evidencing shares transferred
pursuant to an Award shall be issued in the sole name of the Grantee.
Notwithstanding the foregoing, as a precondition to a transfer, the Company may
require an acknowledgement by the Grantee as required under Section 9.

            (d) Forfeiture Conditions. The Committee shall specify in an Award
Agreement the conditions under which the Grantee of that Award shall be required
to convey to the Company the shares covered by the Award. Upon the occurrence of
any such specified condition, the Grantee shall forthwith surrender and deliver
to the Company the certificates evidencing such shares as well as completely
executed instruments of conveyance. The Committee, in its discretion, may
provide that certificates for shares transferred pursuant to an 


                                     - 8 -


Award be held in escrow by the Company or an appropriate officer of the Company
until such time as each and every forfeiture condition has lapsed and that the
Grantee be required, as a condition of the transfer, to deliver to such escrow
agent stock powers covering the transferred shares duly endorsed by the Grantee.
Stock certificates evidencing shares subject to forfeiture shall bear a legend
to the effect that the Common Stock evidenced thereby is subject to repurchase
or conveyance to the Company in accordance with an Award made under the Plan and
that the shares may not be sold or otherwise transferred.

            (e) Lapse of Conditions. Upon termination or lapse of each and every
forfeiture condition, the Company shall cause certificates without the legend
referring to the Company's repurchase right (but with any other legends that may
be appropriate) evidencing the shares covered by the Award to be issued to the
Grantee upon the Grantee's surrender of the legended certificates held by him to
the Company.

            (f) Rights as Shareholder. Upon payment of the purchase price, if
any, for shares covered by an Award and compliance with the acknowledgement
requirement of subsection 10(c), the Grantee shall have all of the rights of a
shareholder with respect to the shares of Common Stock covered thereby,
including the right to vote the shares and receive all dividends and other
distributions paid or made with respect thereto.

      11. Adjustments on Changes in Capitalization. The aggregate number of
shares and class of shares as to which Awards or Options may be granted
hereunder, the number of shares covered by each outstanding Option and the
exercise price thereof, and the number of shares subject to forfeiture with
respect to each Award shall be appropriately adjusted in the event of a stock
dividend, stock split, recapitalization or other change in the number or class
of issued and outstanding equity securities of the Company resulting from a
subdivision or consolidation of the Common Stock and/or other outstanding equity
security or a recapitalization or other capital adjustment (not including the
issuance of Common Stock on the conversion of other securities of the Company
which are convertible into Common Stock) affecting the Common Stock which is
effected without receipt of consideration by the Company. In the event of any
adjustment relating to shares covered by an Award and still subject to
forfeiture, the foregoing provisions and the provisions of subsection 10(d)
shall apply to the certificates issued in connection with the adjustment. The
Committee shall have authority to determine the adjustments to be made under
this Section and any such determination by the Committee shall be final, binding
and conclusive; provided, however, that no adjustment shall be made which will
cause an ISO to lose its status as such without the consent of the Optionee.

      12. Amendment of the Plan. The Company's Board may amend the Plan from
time to time in such manner as it may deem advisable. Nevertheless, the
Company's Board may not, without obtaining approval by vote of a majority of the
outstanding voting stock of the Company, within twelve months before or after
such action, change the class of individuals


                                     - 9 -


eligible to receive an ISO, extend the expiration date of the Plan or increase
the maximum number of shares as to which Awards or Options may be granted,
except as provided in Section 11 hereof. No amendment to the Plan shall
adversely affect any outstanding Option or Award, however, without the consent
of its holder.

      13. Continued Employment. The grant of an Award or Option pursuant to the
Plan shall not be construed to imply or to constitute evidence of any agreement,
express or implied, on the part of the Company or any Affiliate to retain an
Optionee or Grantee in the employ of the Company or an Affiliate or as a member
of the Board or in any other capacity.

      14. Withholding of Taxes. Whenever the Company proposes or is required to
deliver or transfer shares or cash in connection with the exercise of an Option,
SAR or Award, the company shall have the right to (a) require the intended
transferee to remit or otherwise make available to the Company an amount
