(c)
    
    A Participants annual retirement benefit means the amount of retirement benefit
attributable to Employer contributions which is payable to him annually under the Plan
adjusted to the actuarially equivalent straight life annuity form using the factors prescribed
in the following paragraphs if such benefit is to be paid in a manner other than to the
Participant for his life only. A Participants annual retirement benefit includes Social
Security supplements described in Code Section 411(a)(9) and benefits transferred from another
defined benefit plan, other than transfers of distributable benefits pursuant to Treasury
Regulations Section 1.411(d)-4, Q&A-3(c), but shall not include benefits attributable to a
Participants employee contributions.For purposes of determining a Participants annual retirement benefit, the following shall
apply:
 (i)
    
    If payment is to be made in a form other than to the Participant for his life
only, and such form is not subject to the requirements of Code Section 417(e)(3), the
actuarially equivalent straight life annuity shall be determined in accordance with the
provisions of subparagraph (A) or (B) below, as applicable.
 (A)
    
    For limitation years beginning before July 1, 2007, the
annual amount of straight life annuity commencing on the same Annuity Starting
Date with the same actuarial present value as the Participants form of payment
computed using the following factors, whichever produces the greater amount:
(I) the interest rate and mortality table otherwise used under the Plan for
purposes of determining Actuarial Equivalence of optional forms not subject to
the requirements of Code Section 417(e)(3) or (II) the applicable mortality
table and 5 percent.(B)
    
    For limitation years beginning on and after July 1, 2007, the
greater of (I) the annual amount of straight life annuity, if any, payable to
the Participant under the Plan commencing at the same Annuity Starting Date as
the Participants form of payment or (II) the annual amount of straight life
annuity commencing at the same Annuity Starting Date that has the same
actuarially equivalent present value as the Participants form of payment
computed using the applicable mortality table and an interest rate of 5
percent.
 (ii)
    
    If payment is to be made to the Participant in a form that is subject to the
requirements of Code Section 417(e)(3), the actuarially equivalent straight life
annuity form shall be:
 (A)
    
    For distributions with an Annuity Starting Date in the 2004 or
2005 Plan Year, the annual amount of straight life annuity commencing on the
same Annuity Starting Date that has the same actuarially equivalent present
value as the Participants form of payment determined using the following,
whichever provides the greater annual amount: (I) the mortality table and
interest rate otherwise used under the Plan for purposes of determining
Actuarial Equivalence of such optional form or (II) the applicable

mortality table and an interest rate of 5.5 percent; provided, however,
that for distributions with an Annuity Starting Date on or after the first
day of the 2004 Plan Year and before January 1, 2005 Plan Year, use of the
interest rate specified in clause (II) shall not reduce the benefit payable
to the Participant below the amount determined using the applicable
interest rate in effect as of the last day of the last Plan Year beginning
before January 1, 2004. For purposes of this subparagraph (A), the
applicable interest rate means the annual rate of interest on 30-year
Treasury securities for the second calendar month preceding the Plan Year in
which the Annuity Starting Date occurs.(B)
    
    For distributions with an Annuity Starting Date after the 2005
Plan Year, the annual amount of straight life annuity commencing on the same
Annuity Starting Date that has the same actuarially equivalent present value as
the Participants form of payment determined using the following, whichever
provides the greatest annual amount: (I) the mortality table and interest rate
otherwise used under the Plan for purposes of determining Actuarial Equivalence
of such optional form; (II) the applicable mortality table and an interest
rate of 5.5 percent; or (III) the applicable mortality table and the 417(e)
interest rate determined as of the second calendar month preceding the Plan
Year in which the distribution is made, divided by 1.05. For purposes of this
subparagraph (B), the 417(e) interest rate means the following: (1) prior to
the Plan Year beginning in 2008, the applicable interest rate described in
subparagraph (A) above and (2) for Plan Years beginning on and after January 1,
2008, the adjusted first, second and third segment rates applied under Code
Section 430(h)(2)(C), computed without regard to a 24 month average; provided,
however, that for Plan Years beginning in 2008, 2009, 2010, and 2011, such rate
shall be blended with the applicable interest rate described in subparagraph
(A) above, as provided in Code Section 417(e)(3)(D)(ii) and (iii).
 (iii)
    
    A form of payment is not subject to the requirements of Code Section 417(e)(3)
if the form of payment is either (A) a nondecreasing annuity (other than a straight
life annuity) payable for a period not less than the life of the Participant (or in the
case of a Qualified Preretirement Survivor Annuity, the life of the Participants
Spouse) or (B) an annuity that decreases during the life of the Participant merely
because of (I) the death of the Participants Beneficiary under a joint and survivor
annuity, but only if the reduction is not below 50 percent of the benefit payable
before the death of the Beneficiary or (II) cessation or reduction of Social Security
supplements or qualified disability payments, as defined in Code Section 411(a)(9).(iv)
    
    No actuarial adjustment shall be made hereunder for (A) survivor benefits
payable to a surviving Spouse under a Qualified Joint and Survivor Annuity to the
extent such benefits would not be payable if the Participants benefit were paid in
another form, (B) benefits that are not directly related to retirement benefits (such
as qualified disability benefits, preretirement incidental death benefits, and

##### 



post-retirement medical benefits), or (C) the inclusion in the form of payment of an
automatic benefit increase feature, provided that (I) the form of payment is not
subject to Code Section 417(e)(3) and would otherwise satisfy the limitations of
this Article and (II) the Plan provides that the amount payable under the form of
payment in any limitation year shall not exceed the limits of this Article
applicable as of the Annuity Starting Date, increased in subsequent years pursuant
to Code Section 415(d). For purposes of clause (C), an automatic benefit increase
feature is included in a form of payment if the form of payment provides for
automatic, periodic increases to benefits paid in that form.(v)
    
    If a Participant has or will have distributions commencing at more than one
Annuity Starting Date, the annual retirement benefit shall be determined as of each
Annuity Starting Date (and shall satisfy the limitations of this Article as of each
such date), actuarially adjusting for past and future distributions of benefits
commencing as of other Annuity Starting Dates. For purposes of this paragraph (v), the
determination of whether a new Annuity Starting Date has occurred shall be made without
regard to Treasury Regulations Section 1.401(a)-20, Q&A 10(d), but with regard to
Treasury Regulations Sections 1.415(b)-1(b)(1)(iii)(B) and (C).
 (d)
    
    The applicable mortality table means the following: (i) prior to the first day of the first
Plan Year beginning on or after January 1, 2008, the table prescribed by the Secretary of the
Treasury, which is the table specified in Revenue Ruling 2001-62 and (ii) on and after the
first day of the first Plan Year beginning on or after January 1, 2008, the applicable Code
Section 417(e)(3) mortality table.(e)
    
    Defined benefit plan and defined contribution plan have the meanings given such terms in
Code Section 415(k).(f)
    
    Defined benefit compensation limitation means 100 percent of a Participants average 415
compensation for his high three consecutive calendar years of service. In the case of a
Participant who has fewer than 10 years of service with the employer, the defined benefit
compensation limitation shall be multiplied by a fraction, (i) the numerator of which is the
number of years (or part thereof, but not less than one) of service with the employer and (ii)
the denominator of which is 10. For purposes of this subsection, a Participant is credited
with a year of service (computed to fractional years) for each Service Computation Period
for which he is credited with the number of Hours of Service required to accrue Credited
Service under the terms of the Plan, taking into account service with the Employers, any
affiliated employer, or a predecessor employer.(g)
    
    Defined benefit dollar limitation means $160,000, as adjusted , effective January 1 of each
year, under Code Section 415(d) in such manner as the Secretary of the Treasury shall
prescribe, and payable in the form of a straight life annuity. A limitation adjusted under
Code Section 415(d) will apply to limitation years ending with or within the calendar year
for which the adjustment applies. A Participants annual retirement benefit shall not be
adjusted to reflect increases in the defined benefit dollar limitation effective for
limitation years beginning after the limitation year in which his termination occurred.

(i)
    
    If the Participant has fewer than 10 years of participation in the Plan, the
defined benefit dollar limitation shall be multiplied by a fraction, (i) the
numerator of which is the number of years (or part thereof, but not less than one) of
participation in the plan and (ii) the denominator of which is 10. For purposes of this
paragraph, a Participant is credited with a year of participation (computed to
fractional years) for each Service Computation Period (as defined for purposes of
crediting Credited Service) for which he is credited with a year (or fraction of a
year) of Credited Service, provided that (A) he is included as a Participant under the
eligibility provisions of the Plan for at least one day of such Service Computation
Period and (B) the Plan is established no later than the last day of such Service
Computation Period. No more than one year of participation shall be credited for a
Service Computation Period.(ii)
    
    If the benefit of a Participant begins prior to age 62, the defined benefit
dollar limitation applicable to the Participant at such earlier age is an annual
benefit payable in the form of a straight life annuity beginning at the Participants
Annuity Starting Date that is:
 (A)
    
    For limitation years beginning before July 1, 2007, the
actuarial equivalent of the defined benefit dollar limitation (adjusted under
(i) above, if required) determined using the following factors, whichever
produces the lesser annual amount: (I) the interest rate and mortality table
(or other tabular factor) specified in Section 6.2 or 7.3, as applicable, for
adjusting benefits for early commencement or (II) the applicable mortality
table and an interest rate of 5 percent.(B)
    
    For limitation years beginning on or after July 1, 2007, the
following, as applicable:
 (I)
    
    If the plan does not provide an immediately
commencing straight life annuity commencing at both age 62 and the
Participants age at his Annuity Starting Date, the actuarial
equivalent of the defined benefit dollar limitation (adjusted under
(i) above, if required) determined using the applicable mortality
table (expressing the Participants age based on completed calendar
months as of the Annuity Starting Date) and an interest rate of 5
percent.(II)
    
    If the plan does provide an immediately
commencing straight life annuity commencing at both age 62 and the
Participants age at his Annuity Starting Date, the lesser of: (a) the
amount determined under (I) above or (b) the defined benefit dollar
limitation (adjusted under (i) above, if required ) multiplied by the
ratio of the annual amount of the immediately commencing straight life
annuity under the Plan at the Participants Annuity Starting Date to
the annual amount of the immediately commencing straight life

annuity under the Plan at age 62, both determined without applying
the limitations of this Article.
  (iii)
    
    If the benefit of a Participant begins after the Participant attains age 65,
the defined benefit dollar limitation applicable to the Participant at the later age
is an annual benefit payable in the form of a straight life annuity beginning at the
Annuity Starting Date that is:
 (A)
    
    For limitation years beginning before July 1, 2007, the
actuarial equivalent of the defined benefit dollar limitation (adjusted under
(i) above, if required) determined using the following factors, whichever
provides the lesser amount: (I) the interest rate and mortality table (or other
tabular factor) used under the Plan to determine Actuarial Equivalence for
purposes of delayed retirement or (II) the applicable mortality table and an
interest rate of 5 percent.(B)
    
    For limitation years beginning on or after July 1, 2007, the
following, as applicable:
 (I)
    
    If the plan does not provide an immediately
commencing straight life annuity commencing at both age 65 and the
Participants age at his Annuity Starting Date, the actuarial
equivalent of the defined benefit dollar limitation (adjusted under
(i) above, if required) determined using the applicable mortality
table (expressing the Participants age based on completed calendar
months as of the Annuity Starting Date) and an interest rate of 5
percent.(II)
    
    If the plan does provide an immediately
commencing straight life annuity commencing at both age 65 and the
Participants age at his Annuity Starting Date, the lesser of: (a) the
amount determined under (I) above or (b) the defined benefit dollar
limitation (adjusted under (i) above, if required ) multiplied by the
ratio of the annual amount of the adjusted immediately commencing
straight life annuity under the Plan at the Participants Annuity
Starting Date to the annual amount of the adjusted immediately
commencing straight life annuity under the Plan at age 65, both
determined without applying the limitations of this Article. The
adjusted immediately commencing straight life annuity at the
Participants Annuity Starting Date is the annual amount of such

annuity payable to the Participant computed disregarding accruals
after age 65, but including actuarial adjustments even if those
adjustments are used to offset accruals and the adjusted immediately
commencing straight life annuity under the Plan at age 65 is the

Participant who is age 65 and has the same Accrued Benefit as the
Participant.
