accordance with the law of the State of New York applicable to contracts made

     4. Grants of Option Rights. The Board of Directors may, from time to time
and upon such terms and conditions as it may determine, authorize the

                                      -3-
<PAGE>

granting to Eligible Employees of Option Rights. Each such grant may utilize any
or all of the authorizations, and shall be subject to all of the limitations,
contained in the following provisions:

          (a) Each grant shall specify the number of shares of Common Stock to
     which it pertains.

          (b) Each grant shall specify an option price per share not less than
     the Market Value per Share on the date of grant.

          (c) Successive grants may be made to the same Eligible Employee
     whether or not any Option Rights previously granted to such Eligible
     Employee remain unexercised. No Eligible Employee may, however, be
     permitted to purchase in the aggregate pursuant to this Plan more than
     300,000 shares of Common Stock, subject to adjustment pursuant to
     Paragraph 7 of this Plan.

          (d) Option Rights granted under this Plan may be (i) options which are
     intended to qualify under particular provisions of the Internal Revenue
     Code, as in effect from time to time, (ii) options which are not intended
     so to qualify, or (iii) combinations of the foregoing.

          (e) The date of grant of each Option Right shall be the date of its
     authorization by the Board of Directors. No Option Right shall be
     exercisable more than 10 years from such date of grant.

          (f) Upon exercise of an Option Right, the option price shall be
     payable (i) in cash, (ii) by the transfer to the Corporation by the
     Optionee of shares of Common Stock or Book Value Shares with a value equal
     to the total option price, or (iii) by a combination of such methods of
     payment.

          (g) Each grant of Option Rights shall be evidenced by an agreement
     executed on behalf of the Corporation by any officer designated by the

                                      -4-
<PAGE>

     Board of Directors for this purpose and delivered to and accepted by the
     Eligible Employee and shall contain such terms and provisions, consistent
     with this Plan, as the Board of Directors may approve.

          (h) No Option Rights, intended to be an Incentive Stock Option, shall
     be granted hereunder to any Optionee which would allow the aggregate fair
     market (determined at the time the Option Rights are granted) of the stock
     subject of all post 1986 Incentive Stock Options, including the Incentive
     Stock Option in question, which such Optionee may exercise for the first
     time during any calendar year, to exceed $100,000. The term "post 1986
     Incentive Stock Options" shall mean all Option Rights, which are intended
     to be Incentive Stock Options, granted on or after January 1, 1987 under
     any Stock Option Plan of the Corporation or its subsidiaries. If the
     Corporation shall ever be deemed to have a "parent," as such term is used
     in Section 422A of the Internal Revenue Code, as amended, then Stock
     Options intended to be Incentive Stock Options, granted after January 1,
     1987, under such parent's Stock Option plans, shall be included with the
     terms of the definition of "post 1986 Incentive Stock Options".

      5. Grants of Appreciation Rights. The Board of Directors may from time to
time authorize the granting of Appreciation Rights in respect of any or all of
the Option Rights under any Outstanding Option (including Outstanding Options
simultaneously granted) to the Optionee thereunder. An Appreciation Right shall
be a right in the Optionee to receive from the Corporation an amount which shall
be determined by the Board of Directors and shall be expressed as a percentage
of the Spread (not exceeding 100%) at the time of exercise. To the extent such
Optionee elects to exercise such Appreciation Right instead of the related
Option Right, the related Option Right shall be

                                      -5-
<PAGE>

cancelled, and vice versa. Each such grant may utilize any or all of the
authorizations, and shall be subject to all of the limitations, contained in the
following provisions:

          (a) Any grant may permit the exercise of an Appreciation Right with
     respect to the value of shares of Common Stock or Book Value Shares or a
     combination thereof covered by the related Option Rights.

          (b) Any grant may specify that the amount payable on exercise of an
     Appreciation Right may be paid by the Corporation in cash, in shares of
     Common Stock or in any combination thereof, and may either grant to the
     Optionee or retain in the Board of Directors the right to elect among those
     alternatives.

          c) Each grant shall provide that the maximum number of shares of
     Common Stock deliverable upon exercise of an Appreciation Right may not
     exceed the number of shares of Common Stock purchasable upon exercise of
     the related Option Rights.

          (d) Any grant may specify waiting periods before exercise and
     permissible exercise dates or periods. No Appreciation Right shall be
     exercisable except at a time when the related Option Right is also
     exercisable.

          (e) Each grant of an Appreciation Right shall be evidenced by an
     agreement executed on behalf of the Corporation by any officer designated
     by the Board of Directors for this purpose and delivered to and accepted by
     the Optionee, which agreement shall describe such Appreciation Right,
     identify the related Option Rights, state that such Appreciation Right is
     subject to all the terms and conditions of this Plan, including the right
     of the Board of Directors to amend, suspend or terminate such Appreciation
     Right as set forth in Paragraph 10(c) of this Plan, and

                                      -6-
<PAGE>

     contain such other terms and provisions, consistent with this Plan, as the
     Board of Directors may approve.

     6. Transferability. No Option Right or Appreciation Right shall be
transferable by an Optionee other than by will or the laws of descent and
distribution. Option Rights and Appreciation Rights shall be exercisable during
the Optionee's lifetime only by the Optionee or by the Optionee's guardian or
legal representative.

     7. Adjustments. The Board of Directors may make or provide for such
adjustments in the maximum numbers of shares of Common Stock specified in
Paragraphs 3(b) and (c) and 4(c) of this Plan, in the numbers of shares of
Common Stock covered by Option Rights and Appreciation Rights granted hereunder,
and in the prices per share applicable under such Option Rights and Appreciation
Rights, as such Board in its sole discretion, exercised in good faith, may
determine is equitably required to prevent dilution or enlargement of the rights
of Optionees that otherwise would result from any stock dividend, stock split,
combination of shares, recapitalization or other change in the capital structure
of the Corporation, merger, consolidation, spin-off, reorganization, partial or
complete liquidation, issuance of rights or warrants to purchase securities, or
any other corporate transaction or event having an effect similar to any of the
foregoing.

     8. Fractional Shares. The Corporation shall not be required to issue any
fractional share of Common Stock pursuant to this Plan. The Board of Directors
may provide for the elimination of fractions or for the settlement of fractions
in cash.

     9. Administration of the Plan.

          (a) This Plan shall be administered by the Board of Directors, which
     may from time to time delegate all or any part of its authority

                                      -7-
<PAGE>

under this Plan to a Compensation and Organization Committee of not less than
three disinterested Directors appointed by the Board of Directors. To the extent
of such delegation, references herein to the "Board of Directors" shall include
the Compensation and Organization Committee. No Option Right or Appreciation
Right shall be granted to any member of the Compensation and Organization
Committee so long as his membership continues.

     (b) The interpretation and construction by the Board of Directors of any
provision of this Plan or of any agreement evidencing the grant of Option Rights
or Appreciation Rights and any determination by the Board of Directors pursuant
to any provision of this Plan or of any such agreement shall be final and
conclusive. No member of the Board of Directors shall be liable for any such
action or determination made in good faith.

10. Amendments, Etc.

     (a) This Plan may be amended from time to time by the Board of Directors
but without further approval by the stockholders of the Corporation no such
amendment shall (i) increase the maximum numbers of shares of Common Stock
specified in Paragraphs 3(b) and (c) and 4(c) of this Plan (except that
adjustments authorized by Paragraph 7 of this Plan shall not be limited by this
provision), (ii) change the definition of "Eligible Employees", or (iii)
materially increase the benefits accruing to Optionees hereunder.

     (b) The Board of Directors may, with the concurrence of the affected
Optionee, cancel any agreement evidencing Option Rights granted under this Plan.
In the event Of such cancellation, the Board of Directors may authorize the
granting of new Option Rights (which may or may

                                      -8-
<PAGE>

not cover the same number of shares which had been the subject of the prior
agreement) in such manner, at such option price and subject to the same terms,
conditions and discretions as, under this Plan, would have been applicable had
the cancelled Option Rights not been granted.

     (c) The Board of Directors may at any time amend, suspend or terminate any
agreement evidencing Appreciation Rights granted under this Plan; in the case of
an amendment, the amended Appreciation Right shall conform to the provisions of
this Plan.

     (d) In the case of any Option or Appreciation Right not immediately
exercisable in full, the Board of Directors in its discretion may accelerate the
time at which Option or Appreciation Rights may be exercised.

11. Assumptions.

     (a) In the event that a corporation is merged into the Corporation, and the
Corporation is the survivor of such merger, the Board of Directors may elect, in
its sole discretion, to assume under this Plan any or all outstanding options
granted by such corporation to its officers and employees under any stock option
plan adopted by it prior to such merger. Such assumptions shall be on such terms
and conditions as the Board of Directors may determine in its sole discretion,
provided, however, that the options as assumed do not provide or contain any
terms, conditions or rights which an Option Right may not provide or contain
under Sections 2 through 10 hereunder.
