3.3
    
    The Committee, subject to the provisions of the Plan, shall make determinations
regarding:
 (a)
    
    The employees or directors who shall receive Options, the times
when such Options shall be granted, the time limits within which Options may be
exercised (subject to the provisions of this Plan), the number of shares
subject to each Option, and the terms and provisions of Stock Option Agreements
(which need not be identical);(b)
    
    Interpretation of Plan provisions;(c)
    
    Rules and regulations relating to the Plan;(d)
    
    Stock Option Agreements under the Plan; and(e)
    
    Other determinations advisable for the proper administration of
the Plan.
 4.
    
    Tax and Other Characteristics of Options.
 4.1
    
    Options granted pursuant to the Plan may be designated, but need not be
designated, as Incentive Options. The Stock Option Agreement shall provide whether an
Option is an Incentive Option or a Non-Qualified Option. In the case of Incentive
Options, the aggregate fair market value of the Stock (at the time the Option is
granted) for Options that are exercisable for the first time by an Optionee during any
calendar year (under all stock option plans of the Corporation) shall not exceed
$100,000. Non-employee directors of the Corporation shall not be eligible for the
grant of Incentive Options.4.2
    
    At all times during the period beginning on the date of grant of the Incentive
Option and ending on the day three months before the date of exercise of an Incentive
Option, the Optionee must be an Employee of the Corporation or a Subsidiary. Such
3-month period shall be extended to twelve (12) months if employment ends due to a
total disability. If the Optionee terminates employment due to death or dies within the
allowable period specified in the Option Agreement for exercise after termination of
employment, the Option may be exercised (to the extent the Optionee was entitled to
exercise the Option on the date of death) by the Optionees estate, or by a person who
acquired the right to exercise the Option by bequest or inheritance, or by a person
designed to exercise the Option upon the Optionees death, but only within a period
ending upon the earlier of (i) 90 days after the date of death or (ii) the expiration
of the term of the Option set forth in the Option Agreement. Additional limitations
may be imposed by the terms of the Option Agreement.

5.1
    
    Subject to adjustments under Section 11, the aggregate number of shares of
Stock that may be issued on the exercise of Options (either as Incentive Options,
Non-Qualified Options, or a combination) shall not exceed 500,000. Such Stock may be
authorized but unissued shares or treasury shares, as the Committee determines.5.2
    
    If an Option expires or is terminated, the shares of Stock allocated for
issuance under such Option may be allocated to a new Option under the Plan.

    Eligibility.
  7.

  8.
    
    Term and Vesting of Options.
 8.1
    
    The Committee shall determine the term of each Option at the Grant Date. In no
case, however, shall the term of any Option exceed ten years from the Grant Date, or
five years in the case of a grant of an Incentive Option to a Ten Percent Shareholder.8.2
    
    Unless otherwise specified by the Committee in the Option Agreement, 25% of the
Options granted to an individual will be exercisable immediately on the Grant Date,
with another 25% becoming exercisable on each of the first, second, and third
anniversary of the Grant Date. Notwithstanding the previous sentence, and unless
otherwise specified by the Committee in the Option Agreement, Options will be 100%
exercisable when the Optionee attains age 65. These provisions are subject to the
other terms and conditions of the Option Agreement (including the termination date of
the Options).

8.3
    
    Unless specifically stated otherwise in the Option Agreement, all outstanding
Options will become vested and exercisable immediately upon a Change of Control of the
Corporation. For this purpose, Change of Control shall be deemed to have occurred
if, after the Effective Date (i) any person (as such term is used in Sections 13(d)
and 14(d) of the Exchange Act), becomes the beneficial owner (as defined in Rule
13d-3 under the Exchange Act), directly or indirectly, of securities of the Corporation
representing twenty-five percent (25%) or more of the combined voting power of the
Corporations then outstanding securities, (ii) upon the first purchase of the
Corporations Stock pursuant to a tender or exchange offer (other than a tender or
exchange offer made by the Corporation) or (iii) directors who are not continuing
directors become a majority of the Board of Directors. A continuing director is a
director who (a) is a director on the date of adoption of this plan, (b) is nominated
to become a director by the Nominating Committee of the corporation and is recommended
by a majority of the continuing directors, or (c) has served as a director for 24
months.8.4
    
    If, in connection with any merger, consolidation, sale or transfer by the
Corporation of substantially all its assets, any Option is not to be assumed by the
surviving corporation or the purchaser, then the Committee, in its sole discretion, may
advance the date on which such Option or any portion of such Option not then
exercisable, may be exercised.
 9.
    
    Payment on Exercise of Options.
  (a)
    
    In cash; or(b)
    
    At the discretion of the Committee, through the delivery of
Stock with a fair market value equal to the exercise price and withholding
taxes, if any; or(c)
    
    At the discretion of the Committee, through a combination of
(a) and (b).
 10.
    
    Non-Transferability of Options.
 10.1
    
    Except as provided in 10.2, below, Options shall not be transferable by the
Optionee, but if an Optionee dies, his or her personal representative may exercise an
Option within 90 days of the date of the Optionees death (if the Option is otherwise
exercisable), subject to Section 4.2.10.2
    
    Options may be transferable pursuant to a valid decree of divorce, provided,
however, that any Incentive Options required to be so transferred shall cease to be
Incentive Options and become Non-Qualified Options.
