 ARTICLE II 
 PLAN PARTICIPATION 
 2.1 Enrollment and Payroll Deductions. Participation in the Plan is voluntary. An Eligible Employee may elect to participate in the
Plan by completing and delivering to the Company enrollment and payroll deduction authorization forms prescribed by the Company authorizing periodic payroll deductions by the Company from such Eligible Employee’s wages of the periodic amount
specified by such Eligible Employee. Payroll deductions with respect to an Eligible Employee shall commence as soon as administratively practicable after the enrollment and payroll deduction authorization forms of such Eligible Employee are received
and accepted by the Company. If a Participant’s wages are paid on a biweekly schedule, then the biweekly payroll deduction amount specified by such Participant in his or her payroll deduction authorization form must be a minimum of $10.00 and
may not exceed $500.00; in the case of Participants whose compensation is paid in a currency other than United States dollars, the applicable limits shall be the approximate equivalents of such minimum and maximum amounts fixed from time to time by
the Company in administratively convenient units of such other currency. If a Participant’s wages are paid on a schedule other than biweekly, then the periodic payroll deductions referred to in this Section 2.1 shall be made with respect
to such Participant in accordance with such schedule as reflected on such Participant’s payroll deduction authorization form; and the Company shall proportionately adjust the minimum and maximum permitted payroll deductions applicable to such
Participant. A Participant may change his or her periodic payroll deduction amount by written notice to the Company in such form as the Company may specify; such change shall be effective as 
  

 3 








 soon as administratively practicable after the change form is received and accepted by the Company. A
Participant may cease participation in the Plan as of any payroll date by giving written notice of such cessation to the Company in such form as the Company may specify at least fifteen (15) days prior to such payroll date. The Agent shall
continue to maintain the Plan account of a Participant who ceases participation in the Plan until such Participant instructs the Agent either to issue the Shares held in such Plan account to such Participant or to sell such Shares and remit the net
proceeds of such sale to such Participant as provided in Section 2.5. 
 2.2 Issuance of Shares to Agent. On the
last business day of each Plan Month, the Company shall notify the Agent in written or electronic form of the aggregate United States dollar amount withheld for each Participant during such Plan Month and shall instruct the transfer agent for the
Shares to issue to the Agent (in such form or nominee name as the Agent may direct) as an original issuance of authorized but unissued Shares or as the reissuance of Shares held by the Company as treasury shares (and shall provide such transfer
agent with such additional documentation as may be required for such purpose) that number of full Shares which is equal to (a) the aggregate United States dollar amount withheld pursuant to the Plan for all Participants during such Plan Month
divided by (b) the Adjusted Price; any portion of such aggregate dollar amount that is insufficient to purchase a full Share shall be carried over to the next Plan Month. Upon the issuance or reissuance of such number of full Shares, the amount
referred to in clause (a) of the preceding sentence (less any amount carried over to the following Plan Month) shall be deemed to have been paid to and received by the Company, and shall be appropriately reflected on the books of the Company,
as the consideration for such number of newly issued or reissued full Shares. For purposes of determining the United States dollar amount withheld from the wages of Participants whose compensation is paid in a currency other than United States
dollars, the amount withheld in such other currency shall be converted to United States dollars on the basis of the applicable exchange rate quoted in The Wall Street Journal or another reliable source for the next-to-the-last business day of
the Plan Month involved. 
 2.3 Allocation of Shares Among Participants. The Agent shall establish and maintain a
separate Plan account for each Participant and shall allocate the Shares acquired by the Agent pursuant to Section 2.2 for a particular Plan Month among the Plan accounts of those Participants whose payroll deductions provided the funds used to
acquire such Shares. Such allocation shall be made in the Plan records maintained by the Agent in proportion to the United States dollar amount of funds so provided by each Participant and, if fractional shares are involved, shall be made to three
decimal places. Subject to the provisions of Section 2.5, the Agent shall hold in its name or the name of its nominee, for the benefit of all Participants, all shares acquired under the Plan. The Agent shall regularly make available to each
Participant, either in written or electronic form, current information with respect to the Participant’s Plan account showing acquisitions of Shares, dividends credited, sales or issuances of Shares, any applicable commissions or fees charged
to such Participant, and the number of Shares then held. 
 2.4 Dividends and Distributions. Dividends and other
distributions by the Company with respect to Shares held by the Agent under the Plan shall be allocated or otherwise dealt with by the Agent as follows: 
  

	 	(a)	Cash Dividends. Cash dividends received by the Agent on Shares allocated to Participants’ Plan accounts shall be used by the Agent to acquire additional
Shares for such Participants by remitting the aggregate amount of such cash dividends to the Company to be added to the amount applied to the next acquisition of Shares from the Company pursuant to Section 2.2. 

  

 4 









	 	(b)	Stock Dividends and Stock Splits. Stock dividends and stock splits shall be credited to Participants having Shares allocated to their Plan accounts to the extent
that such stock dividends and stock splits are attributable to such Shares. 

  

	 	(c)	Stock Rights. If the Company makes available to its stockholders generally rights to subscribe to additional Shares or other securities, then such rights
accruing on Shares held by the Agent under the Plan shall be sold by the Agent and the net proceeds of such sale shall be applied to the acquisition from the Company of additional Shares for Participants in the same manner as cash dividends are
applied. 

 2.5 Issuance of Shares to Participant; Sale of Shares for Participant. Upon the request of a
Participant, the Agent will arrange for some or all of the Shares in such Participant’s Plan account to be issued to such Participant as promptly as practicable. Upon the issuance of such Shares, such Participant’s Plan account will be
appropriately debited. Upon the request of a Participant, the Agent will sell for the account of such Participant any or all of the Shares in such Participant’s Plan account and shall remit the proceeds of such sale, net of applicable brokerage
commissions (if any), to such Participant as promptly as practicable. If a Participant requests that sale proceeds be remitted to such Participant in a currency other than United States dollars, then the requested currency exchange will be made at
the prevailing rate for transactions of the size involved as determined in the sole discretion of the Agent or its designee for such purpose, and such Participant will bear all expenses incurred by the Agent in effecting such currency exchange. The
Agent shall process transactions involving fractional Shares in such manner as the Agent deems appropriate for the particular transaction. Requests by Participants pursuant to this Section 2.5 may be made in writing or by such electronic or
other means as the Agent may provide. 
 2.6 Voting Rights. A Participant will have the right to vote the Shares in his
or her Plan account in accordance with the Agent’s customary procedures for the voting of shares held in “street name” or other similar types of accounts; however, a Participant is not a stockholder of record of the Company with
respect to any Shares held in such Participant’s Plan account. 
 2.7 Expenses. The Company will bear all of the
expenses of administering the Plan, including but not limited to the Agent’s fees and any transfer taxes and expenses of issuing Shares to Participants. However, a Participant will bear any expenses incurred by the Agent in selling Shares held
for such Participant under the Plan, including but not limited to applicable brokerage commissions and currency exchange expenses. 
 2.8 Termination of Eligibility. If a Participant ceases to be eligible to participate in the Plan for any reason, including but not limited to the termination of such Participant’s employment 
  

 5 








 by the Company or a Subsidiary, then such Participant may no longer participate in the Plan through payroll
deductions. If a Participant ceases to be eligible to participate in the Plan for a reason other than such Participant’s death, then the Agent shall maintain such Participant’s Plan account pending the Agent’s receipt of instructions
either from the Participant or from the Company as to the issuance or sale of the Shares in such Plan account in accordance with Section 2.5 If a Participant dies, then the Agent shall maintain the deceased Participant’s Plan account
pending the Agent’s receipt of instructions as to the disposition of such Plan account from the duly authorized representative of the deceased Participant’s estate. 
 2.9 Termination of Plan. If the Company terminates the Plan, then the Agent shall arrange for the full Shares in a Participant’s
Plan account to be issued to such Participant as promptly as practicable and shall sell for the account of such Participant any fractional Shares in such Participant’s Plan account and remit the proceeds of such sale, net of applicable
brokerage commissions (if any), to such Participant as promptly as practicable. However, in its discretion, the Company may provide additional alternatives for the disposition of the Shares in a Participant’s Plan account upon the termination
of the Plan. 
 2.10 Rules for Foreign Jurisdictions. Notwithstanding any other provisions of the Plan to the contrary,
the Company and, to the extent permitted under applicable law, the Chief Executive Officer of the Company or his or her delegate may, in its or his or her sole discretion, amend or vary the terms of the Plan in order to conform such terms to the
requirements of each non-U.S. jurisdiction where a Subsidiary is located or to meet the goals and objectives of the Plan with respect to the Eligible Employees employed in such non-U.S. jurisdiction. Each of the Company, and to the extent permitted
under applicable law, the Chief Executive Officer of the Company or his or her delegate may, where it or he or she deems appropriate in its or his or her sole discretion, establish one or more sub-plans for such purposes. The Company and, to the
extent permitted under applicable law, the Chief Executive Officer of the Company or his or her delegate may, in its or his or her sole discretion, establish administrative rules and procedures to facilitate the operation of the Plan in such
non-U.S. jurisdictions. For purposes of clarity, the terms of the Plan which vary for a particular non-U.S. jurisdiction shall be reflected in a written addendum to the Plan for such non-U.S. jurisdiction.

judgments, alimony, child support, or separate maintenance owed by a Participant nor be transferable by operation of law in the event of a Participant’s bankruptcy or insolvency. 
 3.3 Employment Rights. An Eligible Employee’s election to participate in the Plan and the Company’s acceptance of such
Eligible Employee’s enrollment in the Plan shall not be deemed to constitute a contract of employment between such Eligible Employee and the Company or any Subsidiary. No provision of the Plan shall be deemed to give any Participant any right
(i) to be retained in the employ or other service of the Company or any Subsidiary for any specific length of time, (ii) to interfere with the right of the Company or any Subsidiary to discipline or discharge the Participant at any time,
(iii) to hold any particular position or responsibility with the Company or any Subsidiary, or (iv) to receive any particular compensation from the Company or any Subsidiary. 
 3.4 Withholding; Payroll Taxes. To the extent required by applicable laws and regulations in effect at the time payroll deductions

withheld from such wages by federal, state, local, or other laws by reason of such payroll deductions and the purchase of Shares under the Plan for the benefit of such Participant at a price less than Fair Market Value. 
 3.5 Transfer Upon Death. The Plan account of a Participant may be transferred by will or the laws of descent and distribution upon

 3.6 Amendment. The Board of Directors of the Company may amend the Plan at any time in whole or in part without
terminating the Plan; however, no amendment of the Plan shall decrease the number of Shares already credited to the Plan accounts of Participants. If the Board of Directors of the Company changes the discount from Fair Market Value at which Shares
are to be acquired under the Plan, then the Company shall not implement such change until the then Participants have been notified of such change and have been given a reasonable opportunity to cease participation in the Plan.

on December 31, 1996.
