after the date hereof, in whole or in part, as follows and on or prior the Termination Date:


 


			for 50% of the shares on or after the date hereof; and



			for 100% of the shares on or after the six month anniversary date hereof.



 


(b)          To
the extent vested prior to the Termination Date, this option shall be exercisable by written notice of such exercise, in the form
prescribed by the Board, to the Secretary or Treasurer of the Company at its principal office. The notice shall specify the number
of shares of Common Stock for which the option is being exercised (which number, if less than all of the shares then subject to
exercise, shall be 50 or a multiple thereof) and shall be accompanied by payment (i) in cash or by check in the amount equal to

(d)          To
the extent vested, prior to the Termination Date, this option shall be exercisable only so long as the Optionee shall continue
to be an employee of the Company and within the ninety (90) day period after the date of termination of the Optionee’s employment
with the Company, to the extent vested on the date of such termination; provided however, such termination was without cause.


 


(e)          Notwithstanding
the provision of Section 3(d) above:


 


(i) In the event the
Optionee is unable to continue as an employee of the Company due to his total and permanent disability (as defined in §105(d)(4)
of the Code), , this option may be exercised, to the extent vested on the date of such disability, within the ninety (90) day period
from the date of disability;


 


(ii) In the event of
death of the Optionee, this option may be exercised, to the extent vested on the date of death, at any time within twelve (12)
months following the date of death by the Optionee's estate or by a person who acquired the right to exercise this option by bequest
or inheritance; provided that at the time of his death the Optionee was an employee of the Company; and


 


(iii) In the event the
Optionee’s employment is terminated for cause, this option may be exercised, to the extent vested on the date of such termination,
within the thirty (30) day period after the date of such termination.


 


Notwithstanding the
provisions of this Section (e), in no event shall this option be exercisable after the Termination Date.


 


4.            Anti-Dilution
Provisions.


 


(a)          If
there is any stock dividend, stock split, or combination of shares of Common Stock, the number and amount of shares then subject
to this option shall be proportionately and appropriately adjusted; no change shall be made in the aggregate purchase price to
be paid for all shares subject to this option, but the aggregate purchase price shall be allocated among all shares subject to
this option after giving effect to the adjustment.


 


(b)          If
there is any other change in the Common Stock, including recapitalization, reorganization, sale or exchange of assets, exchange
of shares, offering of subscription rights, or a merger or consolidation in which the Company is the surviving corporation, an
adjustment, if any, shall be made in the shares then subject to this option as the Board of Directors of the Company (the “Board”)
may deem equitable. Failure of the Board to provide for an adjustment pursuant to this subparagraph prior to the effective date
of any Company action referred to herein shall be conclusive evidence that no adjustment is required in consequence of such action.

(c)          If
the Company is merged into or consolidated with any other corporation, or if it sells all or substantially all of its assets to
any other corporation, then either (i) the Company shall cause provisions to be made for the continuance of this option after such
event, or for the substitution for this option of an option covering the number and class of securities which the Optionee would
have been entitled to receive in such merger or consolidation by virtue of such sale if the Optionee had been the holder of record
of a number of shares of Common Stock equal to the number of shares covered by the unexercised portion of this option, or (ii)
the Company shall give to the Optionee written notice of its election not to cause such provision to be made and this option shall
become exercisable in full (or, at the election of the Optionee, in part) at any time during a period of 20 days, to be designated
by the Company, ending not more than 10 days prior to the effective date of the merger, consolidation or sale, in which case this
option shall not be exercisable to any extent after the expiration of such 20-day period.


 


			5.            Investment Representation;
Legend on Certificates; Special Restriction on Resale.



The Optionee agrees
that until such time as a registration statement under the Securities Act of 1933, as amended (the “1933 Act”), becomes
effective with respect to the option and/or the stock, the Optionee is taking this option and will take the stock underlying this
option, for his own account, for investment and not with a view to the resale or distribution thereof. The Company shall have the
right to place upon the face of any stock certificate or certificates evidencing shares issuable upon the exercise of this option
such legend as the Board may prescribe for the purpose of preventing disposition of such shares in violation of the 1933 Act, as
now or hereafter provided.


 


6.            Non-Transferability.


This option shall not be transferable by
the Optionee other than by will or by the laws of descent or distribution, and is exercisable during the lifetime of the Optionee
only by the Optionee.


 


7.            Certain
Rights Not Conferred by Option.


The Optionee shall
not, by virtue of holding this option, be entitled to any rights of a stockholder in the Company.


 


8.            Expenses.


The Company shall pay
all original issue and transfer taxes with respect to the issuance and transfer of shares of Common Stock pursuant hereto and
all other fees and expenses necessarily incurred by the Company in connection therewith.

9.           Miscellaneous.


In no event shall this
option be exercisable after the Termination Date. Nothing herein shall be deemed to create any employment agreement or guaranty
of the Optionee’s position as an employee of the Company or limit in any way the Company's right to terminate Optionee's
position as an employee of the Company at any time.


 


IN WITNESS WHEREOF, the parties have
caused this Agreement to be executed by their respective duly authorized representatives as of the date first above written.
