according to the following vesting schedule (“Vesting Schedule”):

    


    [   Description

    1
Notwithstanding the initial status as an ISO, upon the occurrence of certain
events as provided for in the Code, ISO qualification may
terminate.


    
      
         


      

      
         


        
          

        

      

      
         


      

    

    


    Termination
Period:

    


    This
Option shall be exercisable after Optionee ceases to be a Service Provider as
follows:

    


    (i)           Resignation
— Option shall remain exercisable until the Expiration Date;

    


    (ii)          Termination
for Cause – Option shall terminate immediately.  For purposes
of this Option, cause shall be determined at the sole discretion of management
unless Service Provider is a party to an employment agreement defining such
term.  In such event, “Cause” will have the definition provided for in
the agreement.

    


    (iii)         Death or
Disability—Option shall remain exercisable for a period of 24 months from

              II. 

            	
              AGREEMENT

            


    

    


    1.          Grant of
Option.  The Committee of the Company hereby grants to the
Optionee named in the Notice of Grant (the "Optionee"), an option (the "Option")
to purchase the number of Shares set forth in the Notice of Grant, at the
exercise price per Share set forth in the Notice of Grant (the "Exercise
Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference.  Subject to Section 10.1 of the
Plan, in the event of a conflict between the terms and conditions of the Plan
and this Option Agreement, the terms and conditions of the Plan shall
prevail.

    


    If
designated in the Notice of Grant as an Incentive Stock Option ("ISO"), this
Option is intended to qualify as an Incentive Stock Option as defined in
Section 422 of the Code.  Nevertheless, to the extent that it
exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated
as a Nonstatutory Stock Option ("NSO").

    


    2.          Exercise of
Option.

    


    (a)           Right to
Exercise.  This Option shall be exercisable during its term in
accordance with the Vesting Schedule set out in the Notice of Grant and with the
applicable provisions of the Plan and this Option Agreement.

    


    (b)         Method of
Exercise.  This Option shall be exercisable by delivery of an
exercise notice in the form attached as Exhibit A (the “Exercise Notice”) which
shall state the election to exercise the Option, the number of Shares, with
respect to which the Option is being exercised, and such other representations
and agreements as may be required by the Company. The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares.  This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by the aggregate
Exercise Price.

    


    No Shares
shall be issued pursuant to the exercise of an Option unless such issuance and
such exercise comply with Applicable laws.  Assuming such compliance,
for income tax purposes the Shares shall be considered transferred to the
Optionee on the date on which the Option is exercised with respect to such
Shares.

     

    
      
         

      

      
        -2-

        
          

        

      

      
         

      

    

     

    3.     
      Optionee's
Representations.  In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Option
is exercised, the Optionee shall, if required by the Company, concurrently with
the exercise of all or any portion of this Option, deliver to the Company his or
her Investment Representation Statement in the form attached hereto as
Exhibit B.

    


    4.        
   Lock-Up
Period.  Optionee hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise
transfer any Shares or other securities of the Company during the 180-day period
(or such other period as may be requested in writing by the Managing Underwriter
and agreed to in writing by the Company) (the "Market Standoff Period")
following the effective date of a registration statement of the Company filed
under the Securities Act.  Such restriction shall apply only to
the first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities
Act.  The Company may impose stop-transfer instructions with respect
to securities subject to the foregoing restrictions until the end of such Market
Standoff Period.

    


    5.           
Method of
Payment.  Payment of the aggregate Exercise Price shall be by
any of the following, or a combination thereof, at the election of the
Optionee:

    


    (a)         cash
or check;

    


    (b)         consideration
received by the Company by way of cashless exercise; or

    


    (c)         surrender
of other Shares which, (i) in the case of Shares acquired upon exercise of an
option, have been owned by the Optionee for more than six (6) months on the date
of surrender, and (ii) have a Fair Market Value on the date of surrender equal
to the aggregate Exercise Price of the Exercised Shares.

    


    6.      
    Restrictions on
Exercise.  This Option may not be exercised until such time as
the Plan has been approved by the stockholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any Applicable
Law.

    


    7.    
       Non-Transferability of
Option.  This Option may not be transferred in any manner
otherwise than by will or by the laws of descent or distribution and may be
exercised during the lifetime of Optionee only by Optionee.  The terms
of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

    


    8.       
    Term of
Option.  This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.

    


    9.    
       Tax
Consequences.  Set forth below is a brief summary as of the
date of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares.  THIS SUMMARY IS NECESSARILY
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO
CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

     

    (a)         Exercise of
ISO.  If this Option qualifies as an ISO, there will be no
regular federal income tax liability upon the exercise of the Option, although
the excess, if any, of the Fair Market Value of the Shares on the date of
exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.  In order to
retain the favorable income tax treatment of ISOs, the ISOs must be exercised on
or before three months after retirement.

     

    
      
         

      

      
        -3-

        
          

        

      

      
         

      

    

     

    (b)         Exercise of Nonstatutory
Stock Option.  There may be a regular federal income tax
liability upon the exercise of a Nonstatutory Stock Option.  The
Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the Fair Market Value
of the Shares on the date of exercise over the Exercise Price.  If
Optionee is an Employee or a former Employee, the Company will be required to
withhold from Optionee's compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered at the time of exercise.

    


    (c)         Disposition of
Shares.  In the case of an NSO, if Shares are held for at least
one year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes.  In the case
of an ISO, if Shares transferred pursuant to the Option are held for at least
one year after exercise and of at least two years after the Date of Grant, any
gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal income tax purposes.  If Shares purchased
under an ISO are disposed of within one year after exercise or two years after
the Date of Grant, any gain realized on such disposition will be treated as
compensation income (taxable at ordinary income rates) to the extent of the
difference between the Exercise Price and the lesser of (1) the Fair Market
Value of the Shares on the date of exercise, or (2) the sale price of the
Shares.  Any additional gain will be taxed as capital gain, short-term
or long-term depending on the period that the ISO Shares were held.

    


    (d)         Notice of Disqualifying
Disposition of ISO Shares.  If the Option granted to Optionee
herein is an ISO, and if Optionee sells or otherwise disposes of any of the
Shares acquired pursuant to the ISO on or before the later of (1) the date
two years after the Date of Grant, or (2) the date one year after the date
of exercise, the Optionee shall immediately notify the Company in writing of
such disposition.  Optionee agrees that Optionee may be subject to
income tax withholding by the Company on the compensation income recognized by
the Optionee.

    


    10.          Entire Agreement; Governing
Law.  The Plan is incorporated herein by
reference.  The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee's interest except by means of a writing signed by the
Company and Optionee.  This agreement is governed by the internal
substantive laws but not the choice of law rules of Delaware.

    


    11.          No Guarantee of Continued
Service.  OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF
SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A
SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED,
BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER).  OPTIONEE
FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE
PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT
INTERFERE IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
CAUSE.

reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option.  Optionee hereby agrees to
accept as binding, conclusive and final all decisions or interpretations of the
Committee upon any questions arising under the Plan or this
Option.  Optionee further agrees to notify the Company upon any change
in the residence address indicated below.

    In
connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following:

    


    (a)           Optionee
is aware of the Company's business affairs and financial condition and has
acquired sufficient information about the Company to reach an informed and
knowledgeable decision to acquire the Securities.  Optionee is
acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

    


    (b)           Optionee
acknowledges and understands that the Securities constitute "restricted
securities" under the Securities Act and have not been registered under the
Securities Act in reliance upon a specific exemption there from, which exemption
depends upon, among other things, the bona fide nature of Optionee's investment
intent as expressed herein.  In this connection, Optionee understands
that, in the view of the Securities and Exchange Commission, the statutory basis
for such exemption may be unavailable if Optionee's representation was
predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred sale,
for or until an increase or decrease in the market price of the Securities, or
for a period of one year or any other fixed period in the
future.  Optionee further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.  Optionee further
acknowledges and understands that the Company is under no obligation to register
the Securities.  Optionee understands that the certificate evidencing
the Securities will be imprinted with a legend which prohibits the transfer of
the Securities unless they are registered or such registration is not required
in the opinion of counsel satisfactory to the Company, and any other legend
required under applicable state securities laws.

    


    (c)           Optionee
is familiar with the provisions of Rule 144, each promulgated under the
Securities Act, which, in substance, permit limited public resale of "restricted
securities" acquired, directly or indirectly from the issuer thereof, in a
non-public offering subject to the satisfaction of certain
conditions.  For so long as the Company is subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934,
the Securities may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144.

     

    
      
         

      

      
        
        

        
          

        

      

      
         

      

    

     

    (d)           Optionee
further understands that in the event all of the applicable requirements of
Rule  144 are not satisfied, registration under the Securities Act,
compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rules 144 is not exclusive,
the Staff of the Securities and Exchange Commission has expressed its opinion
that persons proposing to sell private placement securities other than in a
registered offering and otherwise than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their
respective brokers who participate in such transactions do so at their own
risk.  Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.
