	Termination/Cancellation/Rescission.
	  The
	Company may terminate, cancel, rescind or recover an Award immediately
	under certain circumstances, including, but not limited to, the
	Participant’s:
 
 | 
| 
 
	                    
	(a)
 
 | 
 
	actions
	constituting Cause, as defined in the Plan, or the Company’s By-laws or
	Articles of Incorporation, as
	applicable;
 
 | 
| 
 
	                    
	(b)
 
 | 
 
	rendering
	of services for a competitor prior to, or within six (6) months after, the
	exercise of any Option or the termination of Participant’s Service with
	the Company;
 
 | 
| 
 
	                    
	(c)
 
 | 
 
	unauthorized
	disclosure of any confidential/proprietary information of the Company to
	any third party;
 
 | 
| 
 | 
 
	3.
 
 | 
 
	Expiration
	.  The
	Option, including vested Options, shall not be exercisable after the
	Company’s close of business on the last business day that occurs on or
	prior to the Expiration Date. The “Expiration Date” shall be the
	earliest
	to occur
	of:
 
 | 
| 
 
	(a)  
 
 | 
 
	[Ten
	Years from GD];
 
 | 
| 
 
	(b)  
 
 | 
 
	If
	the Participant’s termination of Service as a Director of the Company
	occurs by reason of Cause, the date preceding the date of such
	termination;
 
 | 
| 
 
	(c)  
 
 | 
 
	If
	the Participant’s termination of Service as a Director of the Company is
	for any reason other than (b) above, all Options vested and exercisable as
	of the date of termination will remain exercisable until [ten years from
	GD].  In such case of termination of Service as a Director of
	the Company occurring by reason of death or Disability, then any Options
	unvested prior to the date of such termination shall be fully vested and
	exercisable as of such date of termination. For purposes hereof,
	Disability shall have the meaning of permanent and total disability
	provided within the meaning of Section 22 (e)(3) of the Internal Revenue
	Code.
 
 | 
| 
 
	4.
 
 | 
 
	Method of Option
	Exercise
	. Subject to the terms of this Agreement and the Plan,
	the Participant may exercise, in whole or in part, the vested portion of
	the Option at any time by complying with any exercise procedures
	established by the Company in its sole discretion.  The
	Participant shall pay the exercise price for the portion of the Option
	being exercised to the Company in full, at the time of exercise,
	either:
 
 | 
| 
 
	(a)  
 
 | 
 
	in
	cash;
 
 | 
| 
 
	(b)  
 
 | 
 
	in
	shares of Stock having a Fair Market Value equal to the aggregate exercise
	price  for the shares of Stock being purchased and satisfying
	such other requirements as may be imposed by the Committee; provided,
	that, such shares of Stock have been held by the Participant for no less
	than six (6) months;
 
 | 
| 
 
	(c)  
 
 | 
 
	partly
	in cash and partly in such shares of Stock;
	or
 
 | 
| 
 
	(d)  
 
 | 
 
	through
	the delivery of irrevocable instructions to a broker to deliver promptly
	to the Company an amount equal to the aggregate exercise price for the
	shares of Stock being purchased (“cashless
	exercise”).
 
 | 
| 
 | 
 
	5.
 
 | 
 
	Taxes.
 
 | 
| 
 | 
 
	        
	(a)
 
 | 
 
	All
	deliveries and distributions under this Agreement are subject to all
	applicable taxes.  As a Director of the Company, the Participant
	is subject to Section 16 (an “Insider”), of the Securities Exchange Act of
	1934 (“Exchange Act”), as well as other relevant securities laws, and any
	surrender of previously owned shares to satisfy tax withholding
	obligations arising upon exercise of an Option, or a ‘cashless exercise’
	must comply with the requirements of Rule 16b-3 promulgated under the
	Exchange Act (“Rule 16b-3”), and other relevant law, regulations and
	Company guidelines.
 
 | 
| 
 | 
 
	        
	(b)
 
 | 
 
	If
	the Fair Market Value of a share of stock on the date the Participant
	exercises the Option is greater than the Exercise Price, the Participant
	will be taxed on the difference multiplied by the number of shares
	purchased with cash at the date of exercise.  This income is
	taxed as ordinary income and subject to various taxes.  The
	income will be reported to the Participant as part of the Participant’s
	compensation on the Participant’s annual Form 1099 issued by the
	Company.
 
 | 
| 
 | 
 
	         (c)
 
 | 
 
	If
	the Participant sells the shares acquired under the Option, a long-term or
	short-term capital gain or loss may also result depending
	on:  (i) the Participant’s holding period for the shares, and
	(ii) the difference between the Fair Market Value of the shares at the
	time of the sale and the Participant’s tax basis in the
	shares.  The holding period is determined from the date the
	Option is exercised.  Under current law, the capital gain or
	loss is long term if the property is held for more than one (1) year, and
	short term if the property is held for less than one (1) year. If the
	Exercise Price of an Option is paid in cash, the tax basis of the shares
	thereby acquired is the sum of (i) the Exercise Price paid for the shares,
	and (ii) the ordinary income, if any, determined by the difference between
	the Fair Market Value of the shares when exercised and the Exercise
	Price.
 
 | 
| 
 | 
 
	6.
 
 | 
 
	Transferability
	.  The
	Option is not transferable other than: (a) by will or by the laws of
	descent and distribution; (b) pursuant to a domestic relations order; or
	(c) to members of the Participant’s immediate family, to trusts solely for
	the benefit of such immediate family members or to partnerships in which
	family members and/or trusts are the only partners, all as provided under
	the terms of the Plan.  After any such transfer, the Option
	shall remain subject to the terms of the
	Plan.
 
 | 
| 
 | 
 
	7.
 
 | 
 
	Adjustment of
	Shares
	.  In the event of any transaction described in
	Section 8.6 of the Plan, the terms of this Option (including, without
	limitation, the number and kind of shares subject to this Option and the
	Exercise Price) shall be adjusted as set forth in Section 8.6 of the
	Plan.
 
 | 
| 
 | 
 
	8.
 
 | 
 
	Not an Employment
	Contract; Shareholder Rights.
	  The grant of an Option
	does not confer on the Participant any contractual employment or
	shareholder rights.  The Participant will not have shareholder
	rights with respect to any shares of stock subject to the Option until the
	Option is exercised and the shares are issued and transferred on the books
	of the Company to the Participant.  No adjustment shall be made
	for dividends, distributions or other rights for which the record date is
	prior to such date, except as provided under the
	Plan.
 
 | 
| 
 | 
 
	9.
 
 | 
 
	Severability
	.  In
	the event that any provision of this Agreement is found to be invalid,
	illegal or incapable of being enforced by any court of competent
	jurisdiction for any reason, in whole or in part, the remaining provisions
	of this Agreement shall remain in full force and effect to the fullest
	extent permitted by law.
 
 | 
| 
 
	10.
 
 | 
 
	Waiver
	.  Failure
	to insist upon strict compliance with any of the terms and conditions of
	this Agreement or the Plan shall not be deemed a waiver of such term or
	condition.
 
 | 
| 
 
	11.
 
 | 
 
	Notices
	.  Any
	notices provided for in this Agreement or the Plan must be in writing and
	hand delivered, sent by fax or overnight courier, or by postage paid first
	class mail.  Notices are to be sent to the Participant at the
	address indicated by the Company’s records and to the Company at its
	principal executive office.
 
 | 
| 
 
	12.

	Purpose of
	Award
	. The Award is intended to promote goodwill between the
	Participant and the Company and shall not be considered as salary or other
	remuneration for any employment or other services the Participant may
	perform for the Company or any of its affiliates.  The Company’s
	grant of the Option does not confer any contractual or other rights of
	employment or service with the Company.  Benefits granted under
	the Plan shall not be considered as part of the Participant’s salary in
	the event of severance, redundancy or resignation. Granting of the Award
	shall also not be construed as creating any right on the part of
	Participant to receive any additional benefits including awards in the
	future, it being expressly understood and agreed that any future awards
	shall be made solely at the discretion of the
	Company.
 
 | 
| 
 
	4.
 
 | 
 
	Expiration
	.  The
	Option, including vested Options, shall not be exercisable after the
	Company’s close of business on the last business day that occurs on or
	prior to the Expiration Date. The “Expiration Date” shall be the
	earliest
	to occur
	of:
 
 | 
| 
 
	(a)  
 
 | 
 
	[general:
	tenth anniv. GD];
 
 | 
| 
 
	        
	(b)
 
 | 
 
	If
	the Participant’s termination of Service occurs by reason of death or
	Disability, the three (3) year anniversary of the date of such termination
	or the ten (10) year anniversary of the Grant Date, whichever is
	sooner.  In such case of termination of Service occurring by
	reason of death or Disability, then any unvested portion of the Option
	shall be fully vested and exercisable as of such date of termination. For
	purposes hereof, “Disability” shall have the meaning provided under: (i)
	first, an employment agreement between the Participant and the Company;
	(ii) second, if no such employment agreement exists, the long-term
	disability program maintained by the Company or any governmental entity
	covering the Participant; or (iii) third, if no such agreement or program
	exists, permanent and total disability within the meaning of Section 22
	(e)(3) of the Code;
 
 | 
| 
 
	        
	(c)
 
 | 
 
	If
	the Participant’s termination of Service occurs by reason of Cause, the
	date preceding the date of such
	termination;
 
 | 
| 
 
	        
	(d)
 
 | 
 
	If
	the Participant’s termination of Service occurs by reason of Change in
	Control, three (3) months after the date of such
	termination;
 
 | 
| 
 
	        
	(e)
 
 | 
 
	If
	the Participant’s termination of Service occurs by reason of Retirement,
	all Options vested and exercisable as of the date of such termination will
	remain exercisable until the ten (10) year anniversary of the Grant
	Date.  For purposes hereof, “Retirement” shall mean the
	termination of the Participant’s Service following the Participant’s
	attainment of at least (i) five years of employment with the Company
	and
	(ii) 55
	years of age,
	provided,
	however
	, that the Participant’s termination of Service will not be
	deemed to have occurred by reason of Retirement if the Participant’s
	Service has been terminated by reason of Cause, as determined by the
	Company in its sole discretion; or
 
 | 
| 
 
	        
	(f)
 
 | 
 
	If
	the Participant’s termination of Service is for any reason other than (b),
	(c), (d) or (e) above, all Options vested and exercisable as of the date
	of termination will remain exercisable for one (1) month after the
	termination date, after which all unexercised Options are
	terminated.
 
 | 
| 
 
	(a)  
 
 | 
 
	in
	cash;
 
 | 
| 
 
	(b)  
 
 | 
 
	in
	shares of Stock having a Fair Market Value equal to the aggregate exercise
	price  for the shares of Stock being purchased and satisfying
	such other requirements as may be imposed by the Committee; provided,
	that, such shares of Stock have been held by the Participant for no less
	than six months;
 
 | 
| 
 
	(c)  
 
 | 
 
	partly
	in cash and partly in such shares of Stock;
	or
 
 | 
| 
 
	(d)  
 
 | 
 
	through
	the delivery of irrevocable instructions to a broker to deliver promptly
	to the Company an amount equal to the aggregate exercise price for the
	shares of Stock being purchased (“cashless
	exercise”).
 
 | 
| 
 
	6.  
 
 | 
 
	Taxes.
 
 | 
| 
 
	         
	(a)
 
 | 
 
	All
	deliveries and distributions under this Agreement are subject to
	withholding of all applicable taxes based on country specific tax
	requirement.  Please refer to electronic copy of “Taxes” for
	your individual circumstances based on your location.  The
	various methods and manner by which the tax withholding may be satisfied
	are set forth in Section 8.4 of the Plan.  If the Participant is
	subject to Section 16 (an “Insider”), of the Securities Exchange Act of
	1934 (“Exchange Act”) and other securities laws, any surrender of
	previously owned shares to satisfy tax withholding obligations arising
	upon exercise of an Option must comply with the requirements of Rule 16b-3
	promulgated under the Exchange Act (“Rule 16b-3”) and other relevant rules
	and regulations.
 
 | 
| 
 
	         
	(b)
 
 | 
 
	If
	the Fair Market Value of a share of stock on the date the Participant
	exercises the Option is greater than the Exercise Price, the Participant
	will be taxed on the difference multiplied by the number of shares
	purchased with cash at the date of exercise.  This income is
	taxed as ordinary income and subject to various withholding
	taxes.  The Company is required to withhold and remit these
	taxes to the appropriate tax authorities.  If the exercise of
	the Option results in no cash payment to the Participant from which the
	Company could withhold the income and FICA taxes, the Participant will be
	required to provide the Company with an amount of cash sufficient to
	satisfy the Participant’s tax withholding obligations or to make
	arrangements satisfactory to the Company with regard to such taxes, which
	in most instances can be done through the services provided by a
	broker.  If the Participant does not pay the amount of required
	withholding to the Company, the Company will withhold from the shares
	delivered or from other amounts payable to the Participant, the minimum
	amount of funds required to cover all applicable federal, state and local
	income and employment taxes required to be withheld by the Company by
	reason of such exercise of the Option.  The income will be
	reported to the Participant as part of the Participant’s employment
	compensation on the Participant’s annual earnings
	statement.
 
 | 
| 
 
	         
	(c)
 
 | 
 
	If
	the Participant sells the shares acquired under the Option, a long-term or
	short-term capital gain or loss may also result depending
	on:  (i) the Participant’s holding period for the shares, and
	(ii) the difference between the Fair Market Value of the shares at the
	time of the sale and the Participant’s tax basis in the
	shares.  The holding period is determined from the date the
	Option is exercised.  Under current law, the capital gain or
	loss is long term if the property is held for more than one year, and
	short term if the property is held for less than one year. If the Exercise
	Price of an Option is paid in cash, the tax basis of the shares thereby
	acquired is the sum of (i) the Exercise Price paid for the shares, and
	(ii) the ordinary income, if any, determined by the difference between the
	Fair Market Value of the shares when exercised and the Exercise
	Price.
 
 | 
| 
 | 
 
	EACH
	PARTICIPANT IS URGED TO REVIEW THE U.S. TAX COMMUNICATION INFORMATION AND
	TO CONSULT WITH HIS OR HER OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX
	CONSEQUENCES INCLUDING THE APPLICABILITY AND EFFECT OF FEDERAL, LOCAL AND
	OTHER TAX LAWS.
 
 | 
| 
 
	7.
 
 | 
 
	Transferability
	.
	The Option is not transferable other than: (a) by will or by the laws of
	descent and distribution; (b) pursuant to a domestic relations order; or
	(c) to members of the Participant’s immediate family, to trusts solely for
	the benefit of such immediate family members or to partnerships in which
	family members and/or trusts are the only partners, all as provided under
	the terms of the Plan.  After any such transfer, the Option
	shall remain subject to the terms of the
	Plan.
 
 | 
| 
 
	8.
 
 | 
 
	Adjustment of
	Shares
	.  In the event of any transaction described in
	Section 8.6 of the Plan, the terms of this Option (including, without
	limitation, the number and kind of shares subject to this Option and the
	Exercise Price) shall be adjusted as set forth in Section 8.6 of the
	Plan.
 
 | 
| 
 
	9.
 
 | 
 
	Shareholder
	Rights.
	  Participant shall have no rights as a
	stockholder with respect to any shares of Stock subject to the Option
	until the Option is exercised and the shares are issued and transferred on
	the books of the Company to the Participant.  No adjustment
	shall be made for dividends, distributions or other rights for which the
	record date is prior to such date, except as provided under the
	Plan.
 
 | 
| 
 
	10.
 
 | 
 
	Data
	Privacy
	.  In order to perform its requirements under this
	Plan, the Company may process sensitive personal data about the
	Participant.  Such data includes but is not limited to the
	information provided in this grant package and any changes thereto, other
	appropriate personal and financial data about the Participant, and
	information about the Participant’s participation in the Plan and shares
	exercised under the Plan from time to time.  By signing the
	attached acceptance form, the Participant hereby gives explicit consent to
	the Company to process any such data.  The Participant also
	hereby gives explicit consent to the Company
	 
	to transfer any
	personal data outside the country in which the Participant is employed and
	to the United States.  The legal persons for whom the personal
	data is intended includes the Company and any of its subsidiaries, the
	outside plan administrator as selected by the Company from time to time
	and any other person that the Company may find appropriate in its
	administration of the Plan.  The Participant may review and
	correct any personal data by contacting his local Human Resources
	Representative. The Participant understands that the transfer of the
	information outlined here is important to the administration of the Plan
	and failure to consent to the transmission of such information may limit
	or prohibit participation in the
	Plan.
 
 | 
| 
 
	11.

	Severability
	.  In
	the event that any provision of this Agreement is found to be invalid,
	illegal or incapable of being enforced by any court of competent
	jurisdiction for any reason, in whole or in part, the remaining provisions
	of this Agreement shall remain in full force and effect to the fullest
	extent permitted by law.

| 
 
	12.

	to insist upon strict compliance with any of the terms and conditions of

 | 
| 
 
	3.  
 
 | 
 
	Purpose of
	Award
	. The Award is intended to promote goodwill between the
	Participant and the Company and shall not be considered as salary or other
	remuneration for any employment or other services the Participant may
	perform for the Company or any of its affiliates.  The Company’s
	grant of the Award does not confer any contractual or other rights of
	employment or service with the Company.  Benefits granted under
	the Plan shall not be considered as part of the Participant’s salary in
	the event of severance, redundancy or resignation. Granting of the Award
	shall also not be construed as creating any right on the part of
	Participant to receive any additional benefits including awards in the
	future, it being expressly understood and agreed that any future awards
	shall be made solely at the discretion of the
	Company.  
 
 | 
| 
 
	4.  
 
 | 
 
	Rights and
	Restrictions Governing Restricted Stock
	.  As of the Date
	of Award, one or more certificates representing the appropriate number of
	shares of Stock granted to the Participant shall be registered in the
	Participant’s name but shall be held by the Company for the Participant’s
	account.  The Participant shall have all rights of a holder as
	to such shares of Stock (including, to the extent applicable, the right to
	receive dividends and to vote), subject to the following
	restrictions:  (a) the Participant has executed a valid stock
	power on behalf of the Company for such Stock; (b) the Participant shall
	be entitled to delivery of certificates representing shares of Stock when
	restrictions lapse; and (c) none of the Stock may be sold, transferred,
	assigned, pledged or otherwise encumbered or disposed of until the
	restrictions have lapsed.
 
 | 
| 
 
	5.  
 
 | 
 
	Delivery of Restricted
	Stock
	.  As soon as reasonably practicable following the
	date on which restrictions lapse, one or more stock certificates for the
	appropriate number of shares of Stock, free of the restrictions set forth
	in the Agreement, shall be delivered to the Participant or such shares
	shall be credited to a brokerage account if the Participant so directs;
	provided however, that such certificates shall bear such legends as the
	Committee, in its sole discretion, may determine to be necessary or
	advisable in order to comply with applicable federal and state securities
	laws.
 
 | 
| 
 
	6.  
 
 | 
 
	Tax Treatment
	.
	The Participant will be taxed on the difference between any purchase price
	and the  Fair Market Value of the Stock on the date the
	restrictions lapse. This income will be taxed as ordinary income and
	subject to income and FICA withholding taxes. The Company is required to
	withhold and remit these taxes to the appropriate tax authorities. The
	Participant will be required to provide the Company with an amount of cash
	sufficient to satisfy the Participant’s tax withholding obligations or to
	make arrangements satisfactory to the Company with regard to such
	taxes.  The income will be reported to the Participant as part
	of the Participant's employment compensation on the Participant's annual
	earnings statement Form W-2.
 
 | 
|

	Withholding
	.  All deliveries and distributions under this
	Agreement are subject to withholding of all applicable taxes. The various
	methods and manner by which tax withholding may be satisfied are set forth
	in Section 8.4 of the Plan.  If the Participant is subject to
	Section 16 (an “Insider”), of the Securities Exchange Act of 1934
	(“Exchange Act”), any surrender of previously owned shares to satisfy tax
	withholding obligations arising under an Award must comply with the
	requirements of Rule 16b-3 promulgated under the Exchange Act (“Rule
	16b-3”).
 
 | 
|

	family members and/or trusts are the only partners, all as provided under
	the terms of the Plan.  After any such transfer, the Award Stock
	shall remain subject to the terms of the
	Plan.

	Restrictions Governing Restricted Stock
	.  As of the Date
	of Award, one or more certificates representing the appropriate number of
	shares of Stock granted to the Participant shall be registered in the
	Participant’s name but shall be held by the Company for the Participant’s
	account.  The Participant shall have all rights of a holder as
	to such shares of Stock (including, to the extent applicable, the right to
	receive dividends and to vote), subject to the following
	restrictions:  (a) the Participant has executed a valid stock
	power on behalf of the Company for such Stock; (b) the Participant shall
	be entitled to delivery of certificates representing shares of Stock when
	restrictions lapse; and (c) none of the Stock may be sold, transferred,
	assigned, pledged or otherwise encumbered or disposed of until the
	restrictions have lapsed.
 
 | 
| 
 
	4.  
 
 | 
 
	Delivery of Restricted
	Stock
	.  As soon as reasonably practicable following the
	date on which restrictions lapse, one or more stock certificates for the
	appropriate number of shares of Stock, free of the restrictions set forth
	in the Agreement, shall be delivered to the Participant or such shares
	shall be credited to a brokerage account if the Participant so directs;
	provided however, that such certificates shall bear such legends as the
	Committee, in its sole discretion, may determine to be necessary or
	advisable in order to comply with applicable federal and state securities
	laws.
 
 | 
| 
 
	5.  
 
 | 
 
	Tax Treatment
	.
	The Participant will be taxed on the difference between any purchase price
	and the Fair Market Value of the Stock on the date the restrictions lapse.
	This income will be taxed as ordinary income but will not subject to any
	withholding taxes. Instead, the Participant is required to pay any
	applicable taxes to the appropriate tax authorities
	directly.  The income will be reported to the Participant as
	part of the Participant’s fees on the Participant’s annual Form 1099
	issued by the Company.
 
 | 
| 
 
	6.  
 
 | 
 
	Tax
	Withholding
	.  All deliveries and distributions under this
	Agreement are not subject to tax withholding unless required under
	applicable law.  Notwithstanding, the Participant voluntarily
	may elect to have the Company withhold any applicable taxes in accord with
	and as permitted by Section 8.4 of the Plan.  As a Director of
	the Company, the Participant is subject to Section 16 (an “Insider”), of
	the Securities Exchange Act of 1934 (“Exchange Act”), and any surrender of
	previously owned shares to satisfy tax withholding obligations arising
	under an Award must comply with the requirements of Rule 16b-3 promulgated
	under the Exchange Act (“Rule 16b-3”), and any other relevant law,
	regulations and Company guidelines.
 
 | 
| 
 
	7.  
 
 | 
 
	Transferability
	.  The
	Award Stock is not transferable other than: (a) by will or by the laws of
	descent and distribution; (b) pursuant to a domestic relations order; or
	(c) to members of the Participant’s immediate family, to trusts solely for
	the benefit of such immediate family members or to partnerships in which
	family members and/or trusts are the only partners, all as provided under
	the terms of the Plan.  After any such transfer, the Award Stock
	shall remain subject to the terms of the
	Plan.
 
 | 
| 
 
	8.  
 
 | 
 
	Adjustment of
	Shares
	.  In the event of any transaction described in
	Section 8.6 of the Plan, the terms of this Award (including, without
	limitation, the number and kind of shares subject to this Award) shall be
	adjusted as set forth in Section 8.6 of the
	Plan.
 
 | 
| 
 
	9.  
 
 | 
 
	Not an Employment
	Contract
	.  The Company’s grant of the Award does not
	confer any contractual or other rights of employment or service with the
	Company.
 
 | 
| 
 
	10.  
 
 | 
 
	Severability
	.  In
	the event that any provision of this Agreement is found to be invalid,
	illegal or incapable of being enforced by any court of competent
	jurisdiction for any reason, in whole or in part, the remaining provisions
	of this Agreement shall remain in full force and effect to the fullest
	extent permitted by law.
 
 | 
| 
 
	11.  
 
 | 
 
	Waiver
	.  Failure
	to insist upon strict compliance with any of the terms and conditions of
	this Agreement or the Plan shall not be deemed a waiver of such term or
	condition.
 
 | 
| 
 
	12.

	.  Any
	notices provided for in this Agreement or the Plan must be in writing and
	hand delivered, sent by fax or overnight courier, or by postage paid first
	class mail.  Notices are to be sent to the Participant at the
	address indicated by the Company’s records and to the Company at its

	(i)  
 
 | 
 
	Modification of
	definition of eligible retirement plan
	.  For purposes of
	this Section 13.04, an ‘eligible retirement plan’ shall also mean an
	annuity contract described in Code Section 403(b) and an eligible deferred
	compensation plan under Code Section 457(b) that is maintained by a state,
	political subdivision of a state, or any agency or instrumentality of a
	state or political subdivision of a state and which agrees to separately
	account for amounts transferred into such plan from this Plan. The

	definition of eligible rollover distribution to include after-tax Employee
	Contributions
	.  For purposes of this Section 13.04, a
	portion of a distribution shall not fail to be an "eligible rollover
	distribution" merely because the portion consists of after-tax Employee
	Contributions which are not includible in gross income. However, such
	portion may be transferred only to an individual retirement account or
	annuity described in Code Section 408(a) or (b), or to a qualified defined
	contribution plan described in Code Section 401(a) or 403(a) that agrees
	to separately account for amounts so transferred, including separately
	accounting for the portion of such distribution which is includible in
	gross income and the portion of such distribution which is not so
	includible.

	taken into account for purposes of satisfying the minimum contribution
	requirements of Code Section 416(c)(2) and the Plan.  The
	preceding sentence shall apply with respect to Matching Employer
	Contributions under the Plan or, if the Plan provides that the minimum
	contribution requirement shall be met in another plan, such other
	plan.  Matching Employer Contributions that are used to satisfy
	the minimum contribution requirements shall be treated as matching
	contributions for purposes of the actual contribution percentage test and
	other requirements of Code Section
	401(m).
 
 | 
| 
 
	(2)  
 
 | 
 
	Contributions under
	other plans
	.  The Employer may provide in the Adoption
	Agreement that the minimum benefit requirement shall be met in another
	plan (including another plan that consists solely of a cash or deferred
	arrangement which meets the requirements of Code Section 401(k)(12) and
	matching contributions with respect to which the requirements of Code
	Section 401(m)(11) are met).

	Deferral
	Contributions
	.
	  If elected
	by the Employer pursuant to Section 1.05(a) and/or 1.06(a), a Participant
	described in such applicable Section may elect to reduce his Compensation
	by a specified percentage or dollar amount.  The Employer shall
	credit an amount to the Participant’s Account equal to the amount of such
	reduction.  Except as otherwise provided in this Section 4.01,
	such election shall be effective to defer Compensation relating to all
	services performed in the calendar year beginning after the calendar year
	in which the Participant executes the election.  Under no
	circumstances may a salary reduction agreement be adopted
	retroactively.  If the Employer has elected to apply Section
	1.05(a)(2), no amount will be deducted from Bonuses unless the Participant
	has made a separate deferral election applicable to such
	Bonuses.  A Participant’s election to defer Compensation may be
	changed at any time before the last permissible date for making such
	election, at which time such election becomes
	irrevocable.  Notwithstanding anything herein to the contrary,
	the conditions under which a Participant may make a deferral election as
	provided in the applicable salary reduction agreement are hereby
	incorporated herein and supersede any otherwise inconsistent Plan
	provision.
 
 | 
| 
 
	(a) 
	 
 
 | 
 
	Performance
	Based Bonus
	.
	  With
	respect to a Performance-based Bonus, a separate election made pursuant to
	Section 1.05(a)(2) will be effective to defer such Bonus if made no later
	than 6 months before the end of the period during which the services on
	which such Performance-based Bonus is based are
	performed.
 
 | 
| 
 
	(b) 
	 
 
 | 
 
	Fiscal
	Year Bonus
	.
	With respect to a Bonus relating to a period of service coextensive
	with one or more consecutive fiscal years of the Employer, of which no
	amount is paid or payable during the service period, a separate election
	pursuant to Section 1.05(a)(2) will be effective to defer such Bonus if
	made no later than the close of the Employer’s fiscal year next preceding
	the first fiscal year in which the Participant performs any services for
	which such Bonus is payable.

| 
 
	(c)

	Cancellation of Salary
	Reduction Agreement
	.
 
 |

	(d)
 
 | 
 
	Initial
	Deferral Election
	.
	   Notwithstanding
	the above, if the Participant is not an Active Participant, the
	Participant may make an election to defer Compensation within 30 days
	after the Participant becomes a Participant, which election shall be
	effective with respect to Compensation payable for services performed
	during the calendar year (or other deferral period described in (a) or (b)
	above, as applicable) and after the date of such election.  For
	Compensation that is earned based upon a specified performance period
	(e.g., an annual bonus) an election pursuant to this subsection (d) will
	be effective to defer an amount equal to the total amount of the
	Compensation for the performance period multiplied by the ratio of the
	number of days remaining in the performance period after the election over
	the total number of days in the performance
	period.
 
 | 
| 
 | 
 
	(a)
	 
	General.
	  If
	provided by the Employer in Section 1.08, and subject to Section
	1.08(e)(2), if a Participant has a Separation from Service, he will be
	entitled to a benefit equal to (i) the vested percentage(s) of the value
	of the Matching and Employer Contributions credited to his Account, as
	adjusted for income, expense, gain, or loss, such percentage(s) determined
	in accordance with the vesting schedule(s) and methodology selected by the
	Employer in Section 1.08, and (ii) the value of the Deferral Contributions
	to his Account as adjusted for income, expense, gain, or
	loss.  The amount payable under this Section 7.03 will be
	distributed in accordance with Article
	8.
 
 | 
| 
 | 
 
	(b)
	 
	Elapsed
	Time Vesting.
	   Unless otherwise provided by the
	Employer in Section 1.08, vesting shall be determined based on the elapsed
	time method.  For purposes of the elapsed time method, "Years of
	Service" means, with respect to any Participant or Inactive Participant,
	the number of whole years of his periods of service with the Employer and
	any Related Employers (as defined in Section 2.01(a)(26)(A)), subject to
	any exclusion elected by the Employer in Section 1.08(c).  A
	Participant or Inactive Participant will receive credit for the aggregate
	of all time period(s) commencing with his Employment Commencement Date and
	ending on the date a break in service begins, unless any such years are
	excluded by Section 1.08(c).  A Participant or Inactive
	Participant will also receive credit for any period of severance of less
	than 12 consecutive months.  Fractional periods of a year will
	be expressed in terms of days.
 
 | 
| 
 | 
 
	(c)
	 
	Class
	Year Vesting.
	  If provided by the Employer in Section
	1.08, a Participant’s or Inactive Participant’s vested percentage in the
	Matching Contributions and/or Employer Contributions portion(s) of his
	Account shall be determined pursuant to the class year
	method.  Pursuant to such method, amounts attributable to the
	applicable contribution types are assigned to “class years” established in
	the records of the Plan.  Such class years are years (calendar
	or non-calendar) to which the contribution is assigned by the
	Administrator, as described in the Service Agreement between the Trustee
	and the Employer.  The Participant’s or Inactive Participant’s
	vested percentage in amounts attributable to a particular contribution is
	determined from the beginning of the applicable class year to the date the
	Participant or Inactive Participant incurs a Separation from
	Service.  For purposes of the class year method, a Participant
	or Inactive Participant is credited with a Year of Service on the first
	day of each such class year.
 
 | 
| 
 
	(a)  
 
 | 
 
	Events
	triggering the distribution of benefits and the form of such distributions
	are described in Section 1.07(a), pursuant to the Employer’s election
	and/or the Participant’s election, as
	applicable.
 
 | 
| 
 
	(1)  
 
 | 
 
	With
	respect to the form and time of distribution of amounts attributable to a
	Deferral Contribution, a Participant election must be made no later than
	the time by which the Participant must elect to make a Deferral
	Contribution, as described in Section
	4.01.
 
 | 
| 
 
	(2)  
 
 | 
 
	With
	respect to the form and time of distribution of amounts attributable to
	Matching or Employer Contributions, a Participant election must be made no
	later than the time by which a Participant would be required to make a
	Deferral Contribution as described in Section 4.01 with respect to the
	calendar year for which the Matching and/or Employer Contributions are
	credited.  For purposes of applying Section 4.01(d) “Active
	Participant” shall have the meaning assigned in Section
	2.01(a)(2)(B).
 
 | 
| 
 
	(3)  
 
 | 
 
	Notwithstanding
	anything herein to the contrary, an election choosing a distribution
	trigger and payment method pursuant to Section 1.07(a)(1) will only be
	effective with respect to amounts attributable to contributions credited
	to the Participant’s Account for the calendar year (or other deferral
	period described in 4.01(a) or (b)) to which such election
	relates.  Amounts attributable to contributions credited to a
	Participant's account prior to the effective date of any new election will
	not be affected and will be paid in accordance with the otherwise
	applicable election.
 
 | 
| 
 | 
 
	(b)
 
 | 
 
	If
	the Employer elects to permit a distribution election change pursuant to
	Section 1.07(b), then any such distribution election change must satisfy
	(1) through (3) below:
 
 | 
| 
 | 
 
	(1)  Such
	election may not take effect until at least 12 months after the date on
	which such election is made.
 
 | 
| 
 | 
 
	(2)  In
	the case of an election related to a payment not on account of Disability,
	death or the occurrence of an Unforeseeable Emergency, the payment with
	respect to which such election is made must be deferred for a period of
	not less than five years from the date such payment would otherwise have
	been paid (or in the case of installment payments, five years from the
	date the first amount was scheduled to be
	paid).
 
 | 
| 
 | 
 
	(3)  Any
	election related to a payment at a specified time or pursuant to a fixed
	schedule may not be made less than 12 months prior to the date the payment
	is scheduled to be paid (or in the case of installment payments, 12 months
	prior to the date the first amount was scheduled to be
	paid).
 
 | 
| 
 | 
 
	(c)  A
	Participant’s entitlement to installments will not be treated as an
	entitlement to a series of separate
	payments.
 
 | 
| 
 | 
 
	(d)  If
	the Plan does not provide for Plan-level payment triggers pursuant to
	Section 1.07(a)(3), and the Participant does not designate in the manner
	prescribed by the Administrator the method of distribution, and/or the
	distribution trigger (if and as required), such method of distribution
	shall be a lump sum at Separation from
	Service.
 
 | 
| 
 | 
 
	(e)  Notwithstanding
	anything herein to the contrary, with respect to any Specified Employee,
	if the applicable payment trigger is Separation from Service, then payment
	shall not commence before the date that is six months after the date of
	Separation from Service (or, if earlier, the date of death of the
	Specified Employee, pursuant to Section 7.02).  Payments to
	which a Specified Employee would otherwise be entitled during the first
	six months following the date of Separation from Service are delayed by
	six months.
 
 | 
| 
 | 
 
	(f)  Notwithstanding
	anything herein to the contrary, the Administrator may, in its discretion,
	automatically pay out a Participant’s vested Account in a lump sum,
	provided that such payment satisfies the requirements in (1) through (3)
	below:
 
 | 
| 
 
	(1)  
 
 | 
 
	Such
	payment results in the termination and liquidation of the entirety of the
	Participant’s interest under the plan (as defined in 26 CFR section
	1.409A-1(c)(2)), including all agreements, methods, programs, or other
	arrangements with respect to which deferrals of compensation are treated
	as having been deferred under a single nonqualified deferred compensation
	plan under 26 CFR section
	1.409A-1(c)(2);
 
 | 
| 
 
	(2)  
 
 | 
 
	Such
	payment is not greater than the applicable dollar amount under Code
	section 402(g)(1)(B); and
 
 | 
| 
 
	(3)  
 
 | 
 
	Such
	exercise of Administrator discretion is evidenced in writing no later than
	the date of such payment.
 
 | 
| 
 | 
 
	(g)  Notwithstanding
	anything herein to the contrary, the Administrator may, in its discretion,
	delay a payment otherwise required hereunder to a date after the
	designated payment date due to any of the circumstances described in (1)
	through (4) below, provided that the Administrator treats all payments to
	similarly situated Participants on a reasonably consistent
	basis.
 
 | 
| 
 
	(1)  
 
 | 
 
	In
	the event the Administrator reasonably anticipates that, if the payment
	were made as scheduled, the Employer’s deduction with respect to such
	payment would not be permitted due to the application of Code section
	162(m), provided the delay complies with the conditions in 26 CFR section
	1.409A-2(b)(7)(i).
 
 | 
| 
 
	(2)  
 
 | 
 
	In
	the event the Administrator reasonably anticipates that the making of such
	payment will violate Federal securities laws or other applicable law,
	provided the delay complies with the conditions in 26 CFR section
	1.409A-2(b)(7)(ii).
 
 | 
| 
 
	(3)  
 
 | 
 
	Upon
	such other events and conditions as the Commissioner of the Internal
	Revenue Service may prescribe in generally applicable guidance published
	in the Internal Revenue Bulletin.
 
 | 
| 
 
	(4)  
 
 | 
 
	Upon
	a change in control event, provided the delay complies with conditions in
	26 CFR section 1.409A-3(i)(5)(iv).
 
 | 
| 
 | 
 
	(h)  Notwithstanding
	anything herein to the contrary, the Administrator may provide an election
	to change the time or form of a payment hereunder to satisfy the
	requirements of the Uniformed Services Employment and Reemployment Rights
	Act of 1994, as amended, 38 USC sections 4301 through
	4344.
