	Transferability:	These
    Options may not be transferred, except upon your death or as permitted by applicable laws and regulations.
	 	 
	Restriction

	Vesting:	100% on

	Death:	Notwithstanding
    anything herein to the contrary, in the event of your death, all exercisable Options may be exercised by your estate (or as
    may otherwise be provided for by you) at any time prior to the expiration date of the term of the Options.
	 	 
	Fundamental
    Transaction:	Unless
    the Board shall reasonably determine otherwise in good faith, in the event that the Company effects a Fundamental Transaction
    (as defined below), any outstanding Options shall be fully exercisable regardless of the vesting and exercise schedule otherwise
    applicable to such Options.  You shall have the right to receive the consideration per share receivable by other
    holders of shares of Common Stock as a result of such Fundamental Transaction.  If holders of shares of Common Stock
    are given any choice as to the securities, cash or property to be received in a Fundamental Transaction with respect to the
    shares, then you shall be given the same choice.   
	 	 
	 	Notwithstanding
    the foregoing, in the event of a Fundamental Transaction and if the Board may reasonably determine in good faith, the Options
    may be (i) honored or assumed, or new rights substituted therefore (such honored, assumed or substituted award hereinafter
    called an “Alternative Award”), by the Company or its affiliates or any successor entity in the Fundamental Transaction
    immediately following the Fundamental Transaction; provided that any such Alternative Award must provide you with
    (a) rights and entitlements substantially equivalent to or better than the rights, terms and conditions applicable under the
    Options and (b) substantially equivalent value to such Options (determined at the time of the Fundamental Transaction); or
    (ii) purchased by the Company by paying to you an amount of cash equal to the value of the remaining unexercised portion of
    the Options on the date of the consummation of such Fundamental Transaction to be determined by a reasonable method selected
    by the Board in good faith.  In the event that a successor entity shall succeed to, and be substituted for (so that
    from and after the date of such Fundamental Transaction, the provisions of the Options referring to the “Company”
    shall refer instead to the successor entity) the Company, such successor entity may exercise every right and power of the
    Company and shall assume all of the obligations of the Company under Options with the same effect as if such successor entity
    had been named as the Company therein.

	 	For
    purposes of this provision, the term “Fundamental Transaction” shall mean the Company, directly or indirectly,
    in one or more related transactions effects, complete or consummates, as applicable any (i) merger or consolidation of the
    Company with or into another person, or (ii) reclassification, reorganization or recapitalization of the Common Stock or any
    compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities,
    cash or property, (iii) sale, lease, license, assignment, transfer, conveyance or other disposition of 50% or more of its
    assets, (iv) purchase offer, tender offer or exchange offer (whether by the Company or another person) pursuant to which holders
    of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been
    accepted by the holders of 50% or more of the outstanding Common Stock, or (v) stock or share purchase agreement or other
    business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement)
    with another person or group of persons whereby such other person or group acquires more than 50% of the outstanding shares
    of Common Stock (not including any shares of Common Stock held by the other person or other persons making or party to, or
    associated or affiliated with the other persons making or party to, such stock or share purchase agreement or other business
    combination).
	 	 
	Adjustments:	If there
    is any change in the number or kind of Shares of Common Stock outstanding (i) by reason of a stock dividend, spinoff, recapitalization,
    stock split, or combination or exchange of shares, (ii) by reason of a merger, reorganization or consolidation, (iii) by reason
    of a reclassification or change in par value, or (iv) by reason of any other extraordinary or unusual event affecting the
    outstanding stock as a class without the Company’s receipt of consideration, or if the value of outstanding shares of
    stock is substantially reduced as result of a spinoff or the Company’s payment of any extraordinary dividend or distribution,
    the kind and number of Shares covered by, or to be issued or issuable under, any outstanding Options and the price per share
    or the applicable market value of such Options shall be required to be equitably adjusted by the Company to reflect any increase
    or decrease in the number of, or change in the kind or value of, issued Shares to preclude, to the extent practicable, the
    enlargement or dilution of rights and benefits such outstanding Options; provided, however, than any fractional shares resulting
    from such adjustment shall be eliminated.  Any adjustments to outstanding Options shall be consistent with Section 409A
    of the Internal Revenue Code, to the extent applicable.  The adjustments of Options hereunder shall include adjustment
    of Shares, Exercise Price, or other terms and conditions, as the Company deems appropriate so long as the Company acts in
    good faith and in a fair and reasonable manner.  Any adjustments determined by the Company shall be final, binding and
    conclusive so long as the Company acts in good faith and in a fair and reasonable manner.
	 	 
	Amendments;	No amendment, modification or
    termination of your Options 
	Modification;	and/or Agreement shall materially
    impair your rights or obligations 
	Termination:	with respect to the Options
    and under this Stock Option Grant
	without your	consent.
