Date by delivery of a check payable to the Company.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



3. LIMITATIONS ON TRANSFER.



In addition to
any other limitation on transfer created by applicable securities laws, the Purchaser shall not assign, encumber or dispose of any interest in the Shares except in compliance with the restrictions set forth in this paragraph.



| | 3.1 | Repurchase Option. In the event of the voluntary or involuntary termination or cessation of employment or association of the Purchaser with the Company or any subsidiary in
which the Company has a majority ownership interest for any reason whatsoever, with or without cause (including death or disability), the Company shall, upon the date of such termination, have an irrevocable, exclusive option to repurchase (the
Repurchase Option) all or any portions of the Shares held by the Purchaser which are subject to the Repurchase Option as of such date at the original purchase price per share specified in Section1. Termination of the Purchasers
employment with the Company shall not be deemed to have occurred during any period that the Purchaser is on a duly authorized leave of absence from the Company of less than twelve (12) months, or such longer period as the Committee of the Board of
Directors administering the Plan approved in writing. If Purchaser does not return to work with the Company on or prior to the last day of an authorized leave of absence, Purchasers employment with the Company shall be deemed to terminate on
the last day of the authorized leave of absence and the Companys repurchase option specified herein shall become exercisable on such date. For the purposes of this Agreement, an authorized leave of absence shall mean a leave of absence
approved by an officer of the Company and by the Human Resources Department.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Initially, all of the Shares purchased by the Purchaser shall be subject to the Companys Repurchase Option as set forth above. The Shares held by the Purchaser shall be released from the Companys
Repurchase Option under this Section 3.1 as follows:



(a) 50%
of the shares (i.e., xx Shares) shall be released on xx and



---

(b) The remaining 50% of the Shares (i.e.,xxShares) shall be released on provided in each such
case the Purchaser is still employed with the Company on such dates. The continuation of the Purchasers employment with the Company is a material inducement to the Company in selling the Shares to Purchaser and failure to provide services to
the Company, for any reason whatsoever shall trigger the Companys Repurchase Option.



Notwithstanding the foregoing, vesting of the Shares shall be suspended during any authorized unpaid leave of absence (including a leave of absence for military, educational, disability or personal purposes) of more
than thirty (30) days or an authorized paid leave of absence of more than ninety (90) days. The suspension of vesting shall commence on the thirty-first (31st) day of an authorized unpaid leave of absence of more than thirty (30) days or, in the case of an authorized paid leave of absence of more than ninety (90) days, on the ninety-first (91st) day of such leave and suspension of vesting shall terminate on the earlier of (1) the last business day preceding the date on
which such individuals leave of absence terminates or (2) a date twelve (12) months after the commencement of the leave of absence, unless the Compensation Committee of the Board of Directors extends such period. The release dates specified
above shall be extended by a number of days equal to the number of days during which vesting was suspended.



Within forty-five (45) days following the Purchasers termination, the Company shall notify the Purchaser as to whether it wishes to purchase the
Shares pursuant to the exercise of the Repurchase Option. If the Company elects to purchase said Shares hereunder, it shall set a date for the closing of the transaction at a place specified by the Company not later than thirty (30) days from the
date of such notice. At such closing, the Company shall tender payment for the Shares and the certificate or certificates representing the Shares so purchased shall be cancelled. The Purchaser hereby authorizes and directs the Secretary or Transfer
Agent of the Company to transfer the Shares as to which the Repurchase Option has been exercised from the Purchaser to the Company. Except as provided under Section 3.5, the Purchaser shall not transfer by sale, assignment, hypothecation, donation
or otherwise any of the Shares or any interest therein prior to the release of such Shares from the Repurchase Option. The Purchaser further authorizes the Company to refuse or to cause its Transfer Agent to refuse to transfer or record any Shares
to be transferred in violation of this Agreement.



| | 3.2 | Assignment by Company. The Companys Repurchase Option may be assigned in whole or in part to any shareholder or shareholders of the Company or other persons or
organizations.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3.3 | Obligations Binding Upon Transferees. All transferees of Shares or any interest therein will receive and hold such Shares or interests subject to the provisions of this
Agreement including, insofar as applicable, the Companys Repurchase Option under Section 3 and the Companys rights under Section 2. Any sale, transfer or other disposition of the Shares or any interest therein in violation of this
Agreement shall be void and without effect.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3.4 | Replacement Certificate. In the event the restrictions imposed by this Agreement shall be terminated as provided in this Section 3, a new certificate or certificates
representing the Shares shall be issued, on request, without the legend referred to in Section 5 herein.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3.5 | Excluded Transfers. The restrictions on transfer of this Section 3 shall not apply to an inter-vivos transfer to the Purchasers ancestors or descendants or spouse or to
a trustee for their benefit, provided that such transferee shall agree in writing to take such Shares subject to all the terms of this Agreement, including restrictions on further transfer.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



4. ESCROW.



| | 4.1 | Delivery of Certificate to Escrow Agent. As security for the Purchasers performance of the terms and provisions of this Agreement and to ensure the availability for
delivery of the Shares upon the Companys exercise of its Repurchase Option, the Purchaser agrees to deliver to the Secretary of the Company (sometimes referred to as the Escrow Agent as the context requires) the certificate or
certificates representing the Shares and his duly executed blank stock assignment in the form attached as Exhibit A hereto for use in transferring all or a portion of said Shares if, as and when required pursuant to Section 3 above.

which joint escrow instructions shall be signed by the Purchaser, the Company and the Escrow Agent at the Closing.



5. LEGENDS.



The certificate or certificates representing the Shares shall bear the following legend:



THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO REPURCHASE PROVISIONS IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT
BETWEEN THE COMPANY AND THE SHARE HOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.



6. SECTION 83(b); SATISFACTION OF WITHHOLDING OBLIGATION.



The Purchaser shall notify the Company in writing if the Purchaser files an election pursuant to Section 83(b) of the Internal Revenue Code of 1986 (an
83(b) Election) with the Internal Revenue Services within thirty (30) days from the date of the sale of the Shares hereunder. The Company intends to claim a tax deduction for any amount which is taxable to the Purchaser regardless of
whether such an election is filed.



IF SUCH AN ELECTION IS NOT
FILED, THE PURCHASER ACKNOWLEDGES THAT THE COMPANY HAS THE RIGHT TO SATISFY ANY PORTION OF ANY WITHHOLDING TAX OBLIGATIONS TO WHICH THE COMPANY MAY BE SUBJECT IN CONNECTION WITH THE SHARES BY SELLING SUFFICIENT SHARES ON BEHALF OF THE PURCHASER
WHICH ARE NO LONGER SUBJECT TO THE REPURCHASE OPTION AND/OR BY WITHHOLDING CERTAIN AMOUNTS FROM PURCHASERS FUTURE SALARY PAYMENTS. IN THE EVENT THAT THE COMPANY DESIREs TO SATISFY THE WITHHOLDING TAX OBLIGATIONS THROUGH THE SALE OF SHARES
WHICH ARE NO LONGER SUBJECT TO THE REPURCHASE OPTION, THE COMPANY SHALL NOTIFY THE ESCROW AGENT TO SELL, AT THE THEN CURRENT MARKET PRICE, A SUFFICIENT PORTION OF SUCH PURCHASERS SHARES WHICH ARE NO LONGER SUBJECT TO THE REPURCHASE OPTION, TO
SATISFY THE AMOUNT OF COMPANYS WITHHOLDING TAX OBLIGATION, AND TRANSFER TO COMPANY SUCH PROCEEDS DERIVED FROM SUCH SALE AS WILL BE NECESSARY TO SATISFY SUCH PORTION OF COMPANYS WITHHOLDING TAX OBLIGATION AS THE COMPANY MAY ELECT.



PURCHASER ACKNOWLEDGES THAT THE COMPANY HAS DISCLOSED TO HIM
OR TO HER THAT IF HE OR SHE FILES AN 83(b) ELECTION, THE SPREAD BETWEEN THE PURCHASE PRICE OF THE SHARES AND THE FAIR MARKET VALUE OF THE SHARES ON THE DATE OF PURCHASE WILL BE IMMEDIATELY TAXABLE TO HIM OR HER AS ORDINARY INCOME AND THE COMPANY
WILL BE REQUIRED TO WITHHOLD CERTAIN AMOUNTS FROM HIS OR HER PAYCHECK. THE SHARES WILL NOT BE SALEABLE TO PAY SUCH TAXES DUE TO THE COMPANYS REPURCHASE OPTION. IF PURCHASER DOES NOT FILE SUCH AN 83(b) ELECTION, THE SPREAD BETWEEN THE PURCHASE
PRICE AND THE FAIR MARKET VALUE OF THE SHARES WHICH VEST WILL BE TAXABLE AS ORDINARY INCOME TO PURCHASER ON THE DATE UPON WHICH SUCH SHARES VEST AND THE COMPANY WILL BE REQUIRED TO WITHHOLD CERTAIN AMOUNTS FROM PURCHASERS PAYCHECK. FURTHER,
THE COMPANY RESERVES THE RIGHT TO SATISFY, EITHER IN WHOLE OR IN PART, ANY WITHHOLDING OBLIGATION, TO WHICH THE COMPANY MAY BE SUBJECT WITH RESPECT TO PURCHASERS SHARES, BY REQUIRING THE ESCROW AGENT TO SELL, AT THE THEN CURRENT MARKET PRICE,
A SUFFICIENT PORTION OF PURCHASERS SHARES WHICH ARE NO LONGER SUBJECT TO THE REPURCHASE OPTION, TO SATISFY ALL OR A PORTION OF THE COMPANYS WITH HOLDING TAX OBLIGATION, AND TRANSFER TO COMPANY THE PROCEEDS DERIVED OF SUCH SALE.
