“5.04 MAXIMUM RETIREMENT BENEFITS

(a) In no event shall the annual benefit distributed or payable to any Participant exceed the Section 415 limit described in paragraph (b). To the extent necessary to comply with Section 411(b) of the Code, if the benefit the Participant would otherwise accrue in a Limitation Year would produce an annual benefit in excess of the Section 415 limit described in paragraph (b), the benefit will be limited (or the rate of accrual reduced) to a benefit that does not exceed such limit. This Section 5.04 is intended to comply with Section 415(b) of the Code, the terms of which are hereby incorporated by reference, and this Section shall be so construed.

(b) The Section 415 limit is lesser of (i) and (ii) below:

(i) the dollar limitation set forth in Section 415(b)(1)(A) of the Code, or

(ii) 100% of the Participant’s average annual Section 415 Compensation (as defined in paragraph (d)) for the three consecutive calendar years (or, if his period of employment is less than three years, for his entire period of employment) during which he or she received the greatest aggregate Section 415 Compensation.

(c) In no event shall the limitations in paragraph (b) be less than $10,000 if the Participant has not at any time participated in a defined contribution plan maintained by the Employer or an Affiliated Employer.

the Employer or Affiliated Employer on behalf of the Employee pursuant to a salary reduction agreement under any plan described in Section 125, 132(f)(4), 401(k), 403(b) or 457(b) of the Code, but excluding amounts to any other plan of deferred compensation, and which are not includable in the Employee’s gross income for the taxable year in which contributed, or any distributions from a plan of deferred compensation, except as allowed by law. Subject to paragraph (n), Section 415 Compensation for a Limitation Year is the Section 415 Compensation actually paid or made available during such Limitation Year. Back pay, within the meaning of Treas. Reg. Section 1.415(c)-2(g)(8), shall be treated as Section 415 Compensation for the Limitation Year to which the back pay relates to the extent the back pay represents wages and compensation that would otherwise be included under this definition. Section 415 Compensation for any Limitation Year shall not exceed the limitation under Code Section 401(a)(17) that is in effect for the calendar year in which such Limitation Year begins.

(e) The dollar limitation described in paragraph (b)(i) above shall be increased by the cost of living adjustment factor prescribed by the Secretary of the Treasury under Section 415(d) of the Code. Such adjustment factor shall be applied to all Participants, including Participants and Beneficiaries receiving benefits from the Plan and to such items as the Secretary shall prescribe.

(f) If the benefit payable to a Participant commences prior to age 62, the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) shall be the lesser of: (A) the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) multiplied by the ratio of the annual amount of the straight life annuity commencing at his benefit commencement date, over the annual amount of the straight life annuity commencing at age 62 (both determined without regard to the Code Section 415 limits), or (B) such limit, after the application of an actuarial equivalent reduction from age 62 to his age as of his benefit commencement date, using a 5 percent interest rate assumption and the applicable mortality table as defined in Code Section 417(e)(3)(B) and as prescribed by Revenue Ruling 2007-67 and by subsequent guidance issued by the Commissioner of the Internal Revenue Service effective for the benefit commencement date. No adjustment shall be made to reflect the probability of a Participant’s death after the benefit commencement date and before age 62.

(g) If the benefit payable to a Participant commences after age 65, the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) shall be the lesser of:

(A) the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) multiplied by the ratio of the annual amount of the immediately commencing straight life annuity payable to the Participant (ignoring accruals after age 65) using the actuarial adjustments in Section 1.02(a) over the annual amount of the straight life annuity that would have been payable at age 65, or (B) the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) actuarially increased using a 5 percent interest rate assumption and the applicable mortality table as defined in Code Section 417(e)(3)(B) and as prescribed by Revenue Ruling 2007-67 and by subsequent guidance issued by the Commissioner of the Internal Revenue Service effective for the benefit commencement date. The probability of the Participant dying after age 65 and before the age at which the payment of benefit would commence shall not be taken into account in increasing the dollar limitation under this paragraph (g).

(h) The annual benefit is a retirement benefit under the Plan which is payable annually in the form of a single life annuity. If the benefit payable to a Participant is not in the normal form of payment nor in the form of a qualified joint and survivor annuity, and it is not payable in a form to which Section 417(e)(3) of the Code applies, then the maximum annual amount determined under paragraph (b) above shall be adjusted such that it is the greater of:

(i) the actuarial equivalent straight life annuity commencing at the same benefit commencement date as the form of benefit payable to the Participant using the Plan’s factors for determining Actuarial Equivalence, and

(ii) the actuarial equivalent straight life annuity commencing at the same benefit commencement date as the form of benefit payable to the Participant using an interest rate of 5% and the applicable mortality table as defined in Code Section 417(e)(3)(B) and as prescribed by Revenue Ruling 2007-67 and by subsequent guidance issued by the Commissioner of the Internal Revenue Service for that benefit commencement date.

(i) If the benefit is payable in a form to which Code Section 417(e)(3) applies, the actuarially equivalent straight life annuity benefit shall be the greatest of:

(i) The annual amount of the straight life annuity commencing at the benefit commencement date that has the same actuarial present value as the particular

form of benefit payable, computed using the Plan’s factors for determining Actuarial Equivalence;

(ii) The annual amount of the straight life annuity commencing at the benefit commencement date that has the same actuarial present value as the particular form of benefit payable, computed using a 5.5% interest assumption and the applicable mortality table for the distribution under Treas. Reg. Section 1.417(e)-1(d)(2); or

(iii) The annual amount of the straight life annuity commencing at the benefit commencement date that has the same actuarial present value as the particular form of benefit payable (computed using the applicable interest rate for the distribution under Treas. Reg. Section 1.417(e)-1(d)(3) and the applicable mortality table for the distribution under Treas. Reg. Section 1.417(e)-1(d)(2)), divided by 1.05.

Notwithstanding the foregoing, for a benefit that has a benefit commencement date in 2004 or 2005, the actuarially equivalent straight life annuity benefit shall be the greater of

(iv) The annual amount of the straight life annuity commencing at the benefit commencement date that has the same actuarial present value as the particular form of benefit payable, computed using the Plan’s Actuarial Equivalence factors; or

(v) The annual amount of the straight life annuity commencing at the benefit commencement date that has the same actuarial present value as the particular form of benefit payable, computed using a 5.5% interest assumption and the applicable mortality table for the distribution under Treas. Reg. Section 1.417(e)-1(d)(2).

Benefits with a benefit commencement date in 2004 shall be calculated in accordance with the requirements of Notice 2004-78, the terms of which are hereby incorporated by reference.

(j) If the Participant has completed less than 10 years of Plan participation, the dollar limitation determined under paragraph (b)(i) above shall be adjusted by multiplying such

amount by a fraction, the numerator of which is the Participant’s number of years of Plan participation (or parts thereof) and the denominator of which is 10.

(k) If the Participant has completed less than 10 years of Service, the maximum amount determined under Section paragraph (b)(ii) and (c) (without regard to paragraph (b)(i) above) shall be adjusted by multiplying such amount by a fraction, the numerator of which is the Participant’s number of years of Service (or parts thereof) and the denominator of which is 10.

(l) In no event shall the provisions of paragraph (j) or paragraph (k) above reduce the limitations in paragraph (b) to an amount less than one-tenth of such limitations, determined without regard to the provisions of paragraph (j) and paragraph (k).

(m) If a Participant is, or has ever been, covered under more than one defined benefit plan maintained by the Employer or an Affiliated Employer, the sum of the Participant’s annual benefits from all such plans may not exceed the maximum permissible amount.

(n) (i) Section 415 Compensation for a Limitation Year shall include amounts earned but not paid during the Limitation Year solely because of the timing of pay periods and pay dates, provided the amounts are paid during the first few weeks of the next Limitation Year, the amounts are included on a uniform and consistent basis with respect to all similarly situated employees, and no compensation is included in more than one Limitation Year.

(ii) Section 415 Compensation for a Limitation Year shall include compensation paid by the later of 2½ months after an Employee’s severance from employment with the Employer maintaining the Plan or the end of the Limitation Year that includes the date of the Employee’s severance from employment with the Employer maintaining the Plan, if:

(A) the payment is regular compensation for services during the Employee’s regular working hours, or compensation for services outside the Employee’s regular working hours (such as overtime or shift differential), commissions, bonuses, or other similar payments, and, absent a severance from employment, the payments would have been paid to the Employee while the Employee continued in employment with the Employer;

(B) the payment is for unused accrued bona fide sick, vacation or other leave that the Employee would have been able to use if employment had continued; or

(C) the payment is received by the Employee pursuant to a nonqualified unfunded deferred compensation plan and would have been paid at the same time if employment had continued, but only to the extent includible in gross income.

Any payments not described above shall not be considered Section 415 Compensation if paid after severance from employment, even if they are paid by the later of 2½ months after the date of severance from employment or the end of the Limitation Year that includes the date of severance from employment, except payments to an individual who does not currently perform services for the employer by reason of qualified military service (within the meaning of Section 414(u)(1) of the Code) to the extent these payments do not exceed the amounts the individual would have received if the individual had continued to perform services for the employer rather than entering qualified military service.”

Also, in this case, the determination of any required minimum distribution under Section 401(a)(9) of the Code that is ineligible for rollover shall be made in accordance with Notice 2007-7, Q&A 17 and 18, 2007-5 I.R.B. 395.

“5.04 MAXIMUM RETIREMENT BENEFIT

(b) The Section 415 limit is lesser of (i) and (ii) below:

(i) the dollar limitation set forth in Section 415(b)(1)(A) of the Code, or

including, but not limited to, overtime pay, tips, bonuses, commissions to paid salesmen, compensation for services on the basis of a percentage of profits, commissions on insurance premiums, fringe benefits, reimbursements, and expense allowances, and including amounts which receive special tax benefits, including amounts contributed by the Employer or Affiliated Employer on behalf of the Employee pursuant to a salary reduction agreement under any plan described in Section 125, 132(f)(4), 401(k), 403(b) or 457(b) of the Code, but excluding amounts to any other plan of deferred compensation, and which are not includable in the Employee’s gross income for the taxable year in which contributed, or any distributions from a plan of deferred compensation, except as allowed by law. Subject to paragraph (n), Section 415 Compensation for a Limitation Year is the Section 415 Compensation actually paid or made available during such Limitation Year. Back pay, within the meaning of Treas. Reg. Section 1.415(c)-2(g)(8), shall be treated as Section 415 Compensation for the Limitation Year to which the back pay relates to the extent the back pay represents wages and compensation that would otherwise be included under this definition. Section 415 Compensation for any Limitation Year shall not exceed the limitation under Code Section 401(a)(17) that is in effect for the calendar year in which such Limitation Year begins.

(f) If the benefit payable to a Participant commences prior to age 62, the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) shall be the lesser of: (A) the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) multiplied by the ratio of the annual amount of the straight life annuity commencing at his Annuity Starting Date, over the annual amount of the straight life annuity commencing at age 62 (both determined without regard to the Code Section 415 limits), or (B) such limit, after the application of an actuarial equivalent reduction from age 62 to his age as of his Annuity Starting Date, using a 5 percent interest rate assumption and the applicable mortality table as defined in Code Section 417(e)(3)(B) and as prescribed by Revenue Ruling 2007-67 and by subsequent guidance issued by the Commissioner of the Internal Revenue Service effective for the Annuity Starting Date. No adjustment

(g) If the benefit payable to a Participant commences after age 65, the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) shall be the lesser of: (A) the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) multiplied by the ratio of the annual amount of the immediately commencing straight life annuity payable to the Participant (ignoring accruals after age 65) using the actuarial adjustments in Section 1.02(a) over the annual amount of the straight life annuity that would have been payable at age 65, or (B) the dollar limitation specified under paragraph (b)(i) above as adjusted by paragraph (e) actuarially increased using a 5 percent interest rate assumption and the applicable mortality table as defined in Code Section 417(e)(3)(B) and as prescribed by Revenue Ruling 2007-67 and by subsequent guidance issued by the Commissioner of the Internal Revenue Service effective for the Annuity Starting Date. The probability of the Participant dying after age 65 and before the age at which the payment of benefit would commence shall not be taken into account in increasing the dollar limitation under this paragraph (g).

(i) the actuarial equivalent straight life annuity commencing at the same Annuity Starting Date as the form of benefit payable to the Participant using the Plan’s factors for determining Actuarial Equivalence, and

(ii) the actuarial equivalent straight life annuity commencing at the same Annuity Starting Date as the form of benefit payable to the Participant using an interest rate of 5% and the applicable mortality table as defined in Code Section 417(e)(3)(B) and as prescribed by Revenue Ruling 2007-67 and by subsequent guidance issued by the Commissioner of the Internal Revenue Service for that Annuity Starting Date.

(i) If the benefit is payable in a form to which Code Section 417(e)(3) applies, the actuarially equivalent straight life annuity benefit shall be the greatest of:

(ii) The annual amount of the straight life annuity commencing at the Annuity Starting Date that has the same actuarial present value as the particular form of benefit payable, computed using a 5.5% interest assumption and the applicable mortality table for the distribution under Treas. Reg. Section 1.417(e)-1(d)(2); or

(iii) The annual amount of the straight life annuity commencing at the Annuity Starting Date that has the same actuarial present value as the particular form of benefit payable (computed using the applicable interest rate for the distribution under Treas. Reg. Section 1.417(e)-1(d)(3) and the applicable mortality table for the distribution under Treas. Reg. Section 1.417(e)-1(d)(2)), divided by 1.05.

Notwithstanding the foregoing, for a benefit that has an Annuity Starting Date in 2004 or 2005, the actuarially equivalent straight life annuity benefit shall be the greater of

(iv) The annual amount of the straight life annuity commencing at the Annuity Starting Date that has the same actuarial present value as the particular form of benefit payable, computed using the Plan’s Actuarial Equivalence factors; or

(v) The annual amount of the straight life annuity commencing at the Annuity Starting Date that has the same actuarial present value as the particular form of benefit payable, computed using a 5.5% interest assumption and the applicable mortality table for the distribution under Treas.

Benefits with an Annuity Starting Date in 2004 shall be calculated in accordance with the requirements of Notice 2004-78, the terms of which are hereby incorporated by reference.

(j) If the Participant has completed less than 10 years of Plan participation, the dollar limitation determined under paragraph (b)(i) above shall be adjusted by multiplying such

amount by a fraction, the numerator of which is the Participant’s number of years of Plan participation (or parts thereof) and the denominator of which is 10.

(B) the payment is for unused accrued bona fide sick, vacation or other leave that the Employee would have been able to use if employment had continued; or

The preceding sentence shall not apply to payments made within a Plan Year with an Annuity Starting Date that occurs on or after the date on which the enrolled actuary for the Plan certifies that the Plan’s AFTAP for a Plan Year is not less than one hundred percent (100%).

(iii) Limited Payment if Percentage is at Least Sixty Percent (60%) but Less Than Eighty Percent (80%).

(A) General. If the Plan’s AFTAP for a Plan Year is sixty percent (60%) or greater but less than eighty percent (80%), no Participant or Beneficiary shall be permitted to elect an optional form of benefit that includes a Prohibited Payment, and the Plan shall not pay any Prohibited Payment, with an Annuity Starting Date on or after the applicable Section 436 Measurement Date. The preceding sentence shall not apply if the present value of the portion of the benefit that is being paid in a Prohibited Payment (as described in Treasury Regulation Section 1.436-1(d)(3)(iii)(B)) does not exceed the lesser of (1) fifty percent (50%) of the present value of the benefit payable in the optional form of benefit that includes the Prohibited Payment or (2) one hundred percent (100%) of the PBGC maximum benefit guarantee amount (as described in Treasury Regulation Section 1.436-1(d)(3)(iii)(C)).

(B) Bifurcation Rules. If an optional form of benefit that is otherwise available under the terms of the Plan is not available as of the Annuity Starting Date because of the application of Section 3.1(d)(iii)(A), then the Participant or Beneficiary shall be permitted to elect to (1) receive the unrestricted portion of the optional form of benefit (determined under the rules of Treasury Regulation Section 1.436-1(d)(3)(iii)(D)) at that Annuity Starting Date, determined by treating the unrestricted portion of the benefit as if it were the Participant’s or Beneficiary’s entire benefit under the Plan, (2) commence benefits with respect to the participant’s or Beneficiary’s entire benefit under the Plan in any other optional form of benefit available under the Plan at the same Annuity Starting Date that satisfies Treasury Regulation Section 1.436-1(d)(3)(i), or (3) defer commencement of the payments to the extent described in Treasury Regulation Section 1.436-1(d)(5). The alternative described under Treas. Reg. §1.436-1(d)(3)(ii)(C) shall not be available under the Plan. With respect to clause (1), if the Participant or Beneficiary elects payment of the unrestricted portion of the benefit (determined under the rules of Treasury Regulation Section 1.436-1(d)(3)(iii)(D)) under

Section 3.1(d)(iii)(B)(1), then the Participant or Beneficiary shall be entitled to elect payment of the remainder of the Participant’s or Beneficiary’s benefits under the Plan in any optional form of benefit at that Annuity Starting Date otherwise available under the Plan that would not have included a Prohibited Payment if that optional form applied to the entire benefit of the Participant or Beneficiary.

(C) One-Time Application. In the case of a Participant with respect to whom a Prohibited Payment (or series of Prohibited Payments under a single optional form of benefit) is made pursuant to Section 3.1(d)(iii)(A), no additional Prohibited Payment shall be made with respect to that Participant during any period of consecutive Plan Years to which the limitations under Sections 3.1(d)(i) or 3.1(d)(ii) apply.

(iv) This subsection (d) shall not apply for any Plan Year during which no benefit accrued with respect to any Participant during such Plan Year.

(e) Limitation on Benefit Accruals for Severe Funding Shortfalls.

(i) General. If the Plan’s AFTAP for a Plan Year is less than sixty percent (60%), benefit accruals under the Plan shall cease as of the applicable Section 436 Measurement Date. If the Plan is required to cease benefit accruals under the preceding sentence, then the Plan shall not be amended in a manner that would increase the liabilities of the Plan by reason of an increase in benefits or establishment of new benefits. If the restrictions described in this paragraph take effect and subsequently cease to apply, the Plan shall not prospectively resume benefit accruals. Further, the Plan shall not retroactively restore benefit accruals relating to the period during which the restrictions were in effect.

(ii) Exemption. Section 3.1(e)(i) shall not apply with respect to a Plan Year, effective as of the first day of the Plan Year, if an Employer makes an additional contribution or provides security in accordance with Treasury Regulation Section 1.436-1(f) or to the extent Section 3.1(e)(i) is otherwise inapplicable in accordance with Code Section 436(f).

(f) Special Rules of Operation for Periods Prior to and After Certification.

(i) Periods Prior to Certification During Which a Presumption Applies. For any period during which a presumption under Code Section 436(h) and Treasury Regulation Sections 1.436-1(h)(1), (2) or (3) applies to the Plan, the limitations under Sections 3.1(b), (c), (d) and (e) shall be applied to the Plan as if the AFTAP for the year were the presumed AFTAP determined under the rules of Code Section 436(h) and Treasury Regulation Sections 1.436-1(h)(1), (2) or (3), as applicable, updated to take into account certain Unpredictable Contingent Event Benefits and Plan amendments in accordance with Code Section 436 and Treasury Regulation Section 1.436-1(g).

(ii) Periods After Certification of AFTAP. Section 3.1(f)(i) shall no longer apply for a Plan Year on and after the date an enrolled actuary for the Plan issues a certification of the AFTAP of the Plan for the current Plan Year, provided that the certification is issued before the first day of the tenth (10th) month of the Plan Year. For example, the limitations on Prohibited Payments under Section 3.1(d) shall apply for distributions with Annuity Starting Dates on and after the date of such certification using the certified AFTAP of the Plan for the Plan Year. Similarly, the prohibitions on accruals under Section 3.1(e) as a result of the enrolled actuary’s certification that the AFTAP of the Plan for the Plan Year is less than sixty percent (60%) shall be effective as of the date of the certification, and any prohibition on accruals shall cease to be effective on the date the enrolled actuary issues a certification that the AFTAP for the Plan for the Plan Year is at least sixty percent (60%).

(g) Definitions. For purposes of this Section 3.1, the following terms have the following meanings:

(i) “AFTAP” means, subject to paragraph (h), the “Adjusted Funding Target Attainment Percentage,” as described in Code Section 436(j)(2) and Treasury Regulation Section 1.436-1(j).

(ii) “Annuity Starting Date” has the meaning described in Treasury Regulation Section 1.436-1(j)(2).

(iii) “Prohibited Payment” means (1) any payment for a month that is in excess of the monthly amount paid under a straight life annuity (plus any social security supplements described in the last sentence of Code Section 411(a)(9)), to a Participant or Beneficiary whose Annuity Starting Date occurs during any period a limitation under Section 3.1(d) is in effect, (2) any payment for the purchase of an irrevocable commitment from an insurer to pay benefits, (3) any transfer of assets and liabilities to another plan maintained by the Company (or by any member of the Company’s controlled group) that is made in order to avoid or terminate the application of the benefit limitations under Code Section 436, and (4) any other amount that is identified as a Prohibited Payment in IRS revenue rulings and procedures, notices, and other guidance published in the Internal Revenue Bulletin. A prohibited payment shall not include the payment of a benefit which under Code Section 411(a)(11) may be immediately distributed without the consent of the Participant.

(iv) “Section 436 Measurement Date” has the meaning described in Treasury Regulation Section 1.436-1(j)(8).

(v) “Unpredictable Contingent Event” means a plant shutdown (whether full or partial) or similar event, or an event (including the absence of an event) other than the attainment of any age, performance of any service, receipt or derivation of any compensation, or the occurrence of death or disability.

(vi) “Unpredictable Contingent Event Benefit” means any benefit or increase in benefits to the extent the benefit or increase would not be payable but for the occurrence of a plant shutdown (whether full or partial) or similar event, or an event (including the absence of an event) other than the attainment of any age, performance of any service, receipt or derivation of any compensation.

(h) Special Rule for Certain Years.

(ii) For purposes of this paragraph (g), the term “applicable provision” means:

(A) Paragraph (d) of this Section 3.1, but only for purposes of applying such paragraph to a payment which, as determined under rules prescribed by the Secretary of Treasury, is a payment under a Social Security leveling option which accelerates payments under the Plan before, and reduces payments after a Participant starts receiving Social Security benefits in order to provide substantially similar aggregate payments both before and after such benefits are received; and

(B) Paragraph (e) of this Section 3.1.”

2. The main part of the Plan (“Salaried”) and Part A (“Hourly”) and Part B (“Jameco”) of the Plan, are hereby amended to comply with certain provisions of the Heroes Earnings Assistance and Tax Relief Act of 2008 (the HEART Act). In particular, Article 16 of the Salaried section of the Plan, and Article 15 of Part A and Article XIV of Part B are hereby amended by adding the following provisions thereto:

“SECTION FOUR — PROVISIONS RELATING TO QUALIFIED MILITARY LEAVE UNDER THE HEROES EARNINGS ASSISTANCE AND RELIEF TAX ACT OF 2008

4.1 Adoption and Effective Date of Amendment. This Item 2 of the Fifth Amendment to the Plan is adopted effective as described below to reflect certain provisions of the Heroes Earnings Assistance and Relief Tax Act (the ‘HEART Act’). This Item 2 of the Fifth Amendment to the Plan is intended as good faith compliance with the requirements of the HEART Act and shall be so construed.

4.2 Supersession of Inconsistent Provisions. This Item 2 of the Fifth Amendment to the Plan shall supersede the provisions of the Plan to the extent that those provisions are inconsistent with the provisions of this Item 2 of the Fifth Amendment.

4.3 Differential Wage Payments and Section 415 Compensation. Effective January 1, 2009 the following provision shall apply with respect to a Participant who receives differential wage payments from the Employer during a period of qualified military service (within the meaning of Section 414(u) of the Code). The differential wage

payments shall be recognized as compensation (within the meaning of Section 415(c)(3) of the Code) and thus shall be recognized in determining the maximum benefit limitation under Code Section 415.

4.4 Survivor Benefits. This Section 4.4 shall apply to benefits payable to a surviving Spouse or a Beneficiary upon the Participant’s death on or after January 1, 2007 while the Participant (who had not incurred a termination of employment at the time that he or she commenced qualified military service) was performing qualified military service (within the meaning of Section 414(u) of the Code). The surviving Spouse or Beneficiary, as the case may be, of the deceased Participant shall be entitled to the death benefit provided under the Plan as if the Participant had returned to employment with the Employer and then incurred a termination of employment with the Employer on account of his or her death. For this purpose, a Participant’s qualified military service (within the meaning of Section 414(u) of the Code) shall be recognized as service for vesting purposes but shall not be recognized as service for benefit accrual purposes.”

3. Except as otherwise provided herein, the Plan shall remain in full force and effect.

IN WITNESS WHEREOF, the Sponsoring Employer has caused this amendment to be executed by its duly authorized representative and its seal affixed hereto on this 28th day of December, 2010.
