 in the Plan and in this Agreement.

2.	Exercise Price.  The Exercise Price to be paid for
 each share of Stock to be acquired upon exercise of the

 of the Stock as of the date of grant of the Option.

3.	Transferability.  The Option granted hereunder shall
 be exercisable during the Optionees lifetime only by the
 Optionee and shall not be assignable or transferable other

 following the Optionees death.

4.	Exercise Terms; Vesting; Procedure.

(a)	Except as provided in Section 6 hereof, the Option

shares with respect to which the Option is being exercised.
  The notice and payment shall be delivered in person or

Option has been exercised.

5.	Vesting.  The Option shall vest and become

6.	Effect of Termination of Employment, Disability or
Death. The following provisions shall govern the exercise
of any Options held by an Optionee at the time the Optionee
 ceases to be an employee of the Company, suffers a Disability,
 or dies.

6.1	Termination of Employment.  In the event that the
Optionee ceases to be an employee of the Company for any
reason other than Disability or death, then the period during
 which each outstanding Option held by such Optionee is to
 remain exercisable shall be limited to the ninety (90) day
period following the date of termination of employment.  Under
 no circumstances, however, shall any such Option be exercisable
 after the specified expiration date of the Option term.  Any
outstanding Option may not be exercised in the aggregate for
 more than the number of vested shares for which the Option is
 exercisable on the date of the termination of employment, and
such Option shall terminate and cease to be outstanding with
respect to any Option shares for which the Option is not at
that time exercisable or in which the Optionee is not otherwise
 at that time vested.

6.2	Disability.  In the event that the Optionee ceases to be
 an employee of the Company by reason of a Disability, then the
 period during which each outstanding Option held by such
Optionee is to remain exercisable shall be limited to a period
 of one (1) year following the date of termination of employment
 due to Disability.  Under no circumstances, however, shall any
 such Option be exercisable after the specified expiration date
 of the Option term as set forth in the Option Agreement.  Any
outstanding Option may not be exercised in the aggregate for
more than the number of vested shares for which the Option is
exercisable on the date of the termination of employment due
 to Disability, and such Option shall terminate and cease to
be outstanding with respect to any Option shares for which the
 Option is not at that time exercisable or in which the Optionee
 is not otherwise at that time vested.

6.3	Death. In the event that the Optionee dies while holding
 one or more outstanding Options, then the period during which
 each outstanding Option held by such Optionee is to remain
exercisable shall be limited to a period of one (1) year
following the date of the Optionees death.  During such limited
 period, the Option may be exercised by the personal representative
 of the Optionees estate or by the person or persons to whom the
option is transferred pursuant to the Optionees will or in
accordance with the laws of descent and distribution.  Under no
circumstances, however, shall any such Option be exercisable
after the specified expiration date of the Option term. Any
outstanding Option may not be exercised in the aggregate for more
 than the number of vested shares for which the Option is
exercisable on the date of the death of the Optionee, and such
 Option shall terminate and cease to be outstanding with respect
 to any Option shares for which the Option is not at that time
exercisable or in which the Optionee is not otherwise at that
time vested.

7.	Adjustments to Upon Certain Events.  In the event that
any change is made to the Stock issuable under the Plan and
the Option granted hereunder by reason of stock split, stock
dividend, recapitalization, combination of shares, exchange of
 shares, repurchase, merger, consolidation, spin-off or other
change affecting the outstanding Stock as a class, the Board
shall make appropriate adjustments to the maximum number of
shares and/or class of shares, and the number of shares and/or
 class of shares and the exercise price per share in effect under
 the Option, in order to prevent the dilution or enlargement of
benefits thereunder.  Any adjustments made by the Board pursuant
 to this Section 7 shall be final, binding and conclusive.
Neither the existence nor the terms of the Plan or this Agreement,
 nor the grant of any Option hereunder, shall affect the right
or power of the Company to make any adjustments, reorganizations,
 reclassifications or other changes to its capital structure or
to merge, consolidate, dissolve, liquidate, sell or transfer any
or all of  its assets or otherwise change its business structure.

Except as expressly provided above, the issuance by the Company
of shares of stock of any class, for cash or property, or for
labor or services, either upon direct sale or upon the exercise
 of rights, warrants or options to subscribe therefor, or upon
 conversions of shares or obligations of the Company convertible
 into such shares or other securities, shall not affect the
number, class or exercise price of shares of Stock then subject
 to the Option, and no adjustment shall be made by reason
thereof.

8.	Requirements of Law.  The Company shall not be required
 to sell or issue shares of its Stock under the Option if the
 sale or issuance would constitute a violation by the Optionee
 or the Company of any provisions of any state or federal law,
 rule or regulation.  In addition, in connection with the
Securities Act of 1933, as amended, upon exercise of the Option,
 the Company shall not be required to issue such shares of
Stock unless the Company has received evidence satisfactory
to it to the effect that the Optionee will not transfer such
shares except pursuant to a registration statement in effect
under the Securities Act of 1933, as amended, or unless an
opinion of counsel to the Company has been received to the
effect that such registration is not required.  Any
determination in this regard by the Company shall be final,
 binding and conclusive.  Certificates representing shares
of Stock issued pursuant to the exercise of the Option will
 be subject to such stop-transfer orders and other restrictions
as may be applicable under federal and state laws, regulations
 and rules, or the requirements of any securities exchange or
 automated quotation system. In the event the shares issuable
on exercise of the Option are not registered under the
Securities Act, the Company may imprint the following legend
 or any other legend which counsel to the Company considers
 necessary or advisable:

The shares of Stock represented by this certificate have not
 been registered under the Securities Act of 1933 or under
 the securities laws of any state and may not be sold or
transferred except upon such registration or upon receipt
 by the Company of an opinion of counsel satisfactory to
the Company that registration is not required for such sale
 or transfer.

The Corporation may, but shall in no event be obligated to,
 register any securities covered hereby pursuant to the
Securities Act of 1933; and in the event any shares are
so registered, the Company may, in its discretion, remove
any legend on certificates representing such shares.  The
 Company shall not be obligated to take any other
affirmative action in order to cause the exercise of the
 Option or the issuance of shares pursuant thereto to
 comply with any state or federal law or regulation.

9.	Investment Purpose.  The Optionee agrees that any
shares of Stock subject to the Option granted hereunder

intention to resell the same, and the Optionee further
agrees to confirm such intention by an appropriate written
 assurances and certificates at the time of exercising an
Option or any portion thereof.

shares of Stock upon exercise of the Option shall be
 subject to any and all applicable federal, state and
local tax withholding and reporting requirements.

no right as a shareholder with respect to the Stock
covered by the Option until the date of issuance of
Stock Certificates for such Stock to the Optionee.

12.	No Employment Obligation.  The granting of any
Option shall not impose upon the Company any obligation
to employ the Optionee.  The right of the Company to
 terminate the employment of the Optionee shall not be

Option has been granted hereunder to the Optionee.
