SECTION I - ESTABLISHMENT AND PURPOSE

 

1.1                               Establishment and Purpose

 

Protein Design Labs, Inc. (PDL), hereby
establishes the Protein Design Labs, Inc. Retiree Health Care Plan (Plan) for
certain eligible former employees of PDL and their eligible dependents.  It is the intention of PDL that this Plan
qualify as an accident and health plan within the meaning of Section 105 of the
Internal Revenue Code (Code) and, to the extent the benefits provided under the
Plan are not discriminatory, that they be eligible for exclusion from gross
income under the Code.

 

1.2                               Exclusive Purpose

 

The exclusive purpose of this Plan is to
provide health-related benefits described herein for the eligible former
employees of PDL and their eligible family members.  No expenses payable under this Plan will be payable under any
other benefit plan of PDL.

 

1.3                               Effective Date

 

The original effective date of the Plan is
June 1, 2003

 

1.4                               Plan Year

 

The Plan Year is December 1 through November 30  of the following calendar
year.

SECTION II -
ELIGIBILITY

 

2.1                               Retiree Eligibility

 

All officers with at least ten full years of
service and who were eligible to participate as employees in the PDL sponsored
health plans made available to the active employees of PDL, who elect to retire
under the terms of the then current PDL retirement requirements, shall become
participants in the plan on the later of the Effective Date of the Plan or,
upon their date of retirement.

 

2.2                               Eligible Dependents

 

For purposes of this Plan, eligible
dependents shall include only those persons who meet the PDL sponsored health
plan definition of dependents for purposes of the plan in which the employee
participated on the day before his/her date of retirement.

 

2.3                               Contribution Requirements

 

In the event that PDL requires contributions
toward the cost of this Plan, coverage under this plan shall not take effect
for persons for whom contributions are required, until such time as the
contribution requirements are met. Contributions, if any, are described in
Appendix A of this Plan.

 

2.4                               Cessation of Participation

 

Eligibility under this Plan shall terminate
upon the earliest of:

 

a)                                      the retiree meets the age requirements for
benefits under Title XVIII of Social Security Act (commonly known as Medicare);

b)                                     the date the retiree dies, except as
provided for under section 2.5 of this Plan;

c)                                      the date the retiree becomes covered under
another group health plan;

d)                                     the date required contributions cease to be
paid; and,

e)                                      the date the spouse or dependent of the
retiree ceases to meet the eligibility requirements under the PDL Health Plan.

 

2.5                               Survivor Benefits

 

In the event the retiree dies prior to
meeting the age requirements for benefits under Medicare, dependents covered
under this Plan on the retiree’s date of death shall remain eligible for
extended benefits under this Plan under the same terms and conditions as
applied on the date of the retiree’s death. In the event that PDL changes the
terms and conditions of this Plan, such changes shall apply to surviving
eligible dependents.

 

2.6                               Newly Acquired Dependents

 

In the event the retiree acquires dependents
while covered under this Plan, and said dependents meet the eligibility
requirements specified in the PDL Health Plan, these newly acquired dependents
shall become eligible to participate subject to the provisions of Section 2.7
of this Plan. Dependents (including spouses) acquired by a surviving spouse
shall not be eligible to participate in this Plan.

 

2.7                               Special Enrollment

 

Subject to the special open enrollment
periods of Section 9801 (f) of the Code, a covered retiree who acquires a
dependent as a result of marriage, birth, adoption or placement for adoption,
may be able to enroll dependents, provided that the retiree requests enrollment
within 30 days after the marriage, birth, adoption, or placement for adoption.
If the retiree fails to complete the

 

2

 

enrollment process on a timely basis, the dependents
may be required to wait until the group’s next open enrollment to obtain
coverage the dependents also may be subject to additional limitations on the
coverage available at that time.

 

2.8                               Qualified Medical Child Support Orders

 

This Plan will also provide benefits as
required by any qualified medical child support order, as defined in ERISA
Section 609(a), and provide benefits to dependent children placed with
participants or beneficiaries for adoption under the same terms and conditions
as apply in the case of dependent children who are natural children of
participants or beneficiaries, in accordance with ERISA Section 609(c).  The Plan will provide a copy of its written
procedures to plan participants upon request.

SECTION III -
BENEFITS

 

3.1                               Benefits Provided

 

A participant, who meets the eligibility
requirements of Section 2 of this Plan, shall be eligible to participate in the
PDL retiree Health Plan. The Benefits under this Plan shall be identical to
those provided under the health plans available to the eligible active
employees of PDL.

 

3.2                               Changes in Benefits

 

In the event that PDL changes the benefits
under its health plans, all such changes in benefits shall apply to this Plan
as of the effective date of the changes to the health plans available to the
eligible active employees of PDL.

 

3.3                               Health Plan Defined

 

For purposes of this Plan, the term health
plan shall include the PDL medical and dental plans available to the eligible
active employees of PDL.

 

3.4                               Amendment and Termination

 

In the event that PDL amends or terminates
this Plan, this Plan will reimburse participants for any benefits payable for
expenses incurred prior to the date of such amendment, modification or
termination.

 

3.5                               Newborns’ and Mothers’ Health Protection Act of 1996

 

Group health plans and health insurance
issuers generally may not, under federal law, restrict benefits for any
hospital length of stay in connection with childbirth for the mother or newborn
child to less than 48 hours following vaginal delivery, or less than 96 hours
following a cesarean section. However, Federal law generally does not prohibit
the mother’s or newborn’s attending provider, after consulting with the mother,
from discharging the mother or her newborn earlier than 48 hours (or 96 hours
as applicable). In any case plans and issuers may not, under Federal law,
require that a provider obtain authorization from the plan or the issuer for
prescribing a length of stay not in excess of 48 hours (or 96 hours).

 

3.6                               The
Federal “Women’s Health and Cancer Rights Act of 1988” requires coverage of
treatment related to mastectomy.

 

If a participant is eligible for mastectomy
benefits under this coverage and elects breast reconstruction in connection with
such mastectomy, the participant is also covered for the following:

 

1.                                       Reconstruction of the breast on which
mastectomy has been performed;

2.                                       Surgery and reconstruction on the other
breast to produce a symmetrical appearance;

3.                                       Prostheses; and,

4.                                       Treatment for physical complications of all
stages of mastectomy, including lymphademas.

 

Coverage for reconstructive breast surgery
may not be denied or reduced on the grounds that it is cosmetic in nature or
that it otherwise does not meet the coverage definition of “medically
necessary”. Benefits will be provided on the same basis as for any other
illness or injury under the relevant health plan.

SECTION IV -
ADMINISTRATION OF THE PLAN

 

4.1                               Administration of the Plan

 

PDL is the Plan Sponsor and Plan
Administrator as defined by ERISA.

 

PDL shall have the duty and authority to
interpret and construe the Plan with regard to all questions of eligibility,
the status and rights of any person under the Plan, and the manner, time, and
amount of payment of any benefits under the Plan. Each Employee shall, from
time to time, upon request of PDL, furnish to PDL such data and information as
PDL shall require in the performance of its duties under the Plan.

 

PDL may adopt such rules and procedures, as
it deems desirable for the administration of the Plan, provided that any such
rules and procedures shall be consistent with provisions of the Plan and ERISA.

 

PDL shall discharge its duties with respect
to the Plan (i) solely in the interest of persons eligible to receive benefits
under the Plan, (ii) for the exclusive purpose of providing benefits to persons
eligible to receive benefits under the Plan and of defraying reasonable
expenses of administering the Plan and (iii) with the care, skill, prudence and
diligence under the circumstances then prevailing that a prudent person acting
in a like capacity and familiar with such matters would use in the conduct of
an enterprise of a like character with like aims.

 

4.2                               Named Fiduciary

 

Pursuant to ERISA Section 402 (a) (1), PDL is
named fiduciary of the Protein Design Labs, Inc.  Retiree Health Plan.

 

4.3                               Appointment of the Plan
Administrator

 

PDL shall designate the Plan Administrator
who shall administer PDL’s Plan. Such Plan Administrator may consist of an
individual, a committee of two or more individuals, whether or not, in either
such case, the individual or any of such individuals are Employees of PDL, a
consulting firm or other independent agent, or PDL itself.  The Plan Administrator shall be charged with
the full power and the responsibility for administering the Plan in all its
details.  If no Plan Administrator has
been appointed by PDL, or if the person designated as Plan Administrator by PDL
is not available to serve as such for any reason, PDL shall be deemed to be the
Plan Administrator.  The Plan
Administrator may be removed by PDL, or may resign by giving notice in writing
to PDL, and in the event of the removal, resignation, death or termination of
service by the Plan Administrator, PDL shall, as soon as practicable, appoint a
successor Plan Administrator, such successor thereafter to have all of the
rights, privileges, duties and obligations of the predecessor Plan
Administrator.

 

4.4                               Powers and Responsibilities

 

(a)                                  Administration of the Plan The Plan Administrator shall have all powers necessary to administer
this Plan, including the power to construe and interpret the Plan documents; to
decide all questions relating to an Employee’s eligibility to participate in
the Plan; to determine the amount, manner, and timing of any payment of
benefits or change in accordance with Section 5 of the Plan; and to appoint or
employ advisors, including legal counsel, to render advice with respect to any
of the Plan Administrator’s responsibilities under the Plan.  Any construction, interpretation, or
application of the Plan by the Plan Administrator shall be final, conclusive
and binding.  All actions by the Plan
Administrator shall be taken pursuant to uniform standards applied to all
persons similarly situated.  The Plan
Administrator shall have no power to add to, subtract from or modify any of the

 

5

 

terms of the Plan, or to add to any benefits provided by the Plan, or
to waive or fail to apply any requirements of eligibility for a benefit under
the Plan.

 

(b)                                  Records and Reports The Plan Administrator shall be responsible for maintaining sufficient
records to reflect the compensation of each Participant for purposes of determining
the amount of compensation of each Participant under the Plan.  The Plan Administrator shall be responsible
for submitting all required reports and notifications relating to the Plan to
Participants or their Beneficiaries, the Internal Revenue Service and the
Department of Labor.

 

(c)                                  Rules and Decisions The Plan Administrator may adopt such rules as it deems necessary,
desirable or appropriate in the administration of the Plan.  All rules and decisions of the Plan
Administrator shall be applied uniformly and consistently to all Employees and
Participants in similar circumstances. 
When making a determination or calculation, the Plan Administrator may
rely upon all such information so finished, including the Participant’s, former
Participant’s or Beneficiary’s current mailing address.

 

4.5                               Allocation of Duties and
Responsibilities

 

The Plan Administrator may by written or
instrument designate persons other than the Plan Administrator to carry out any
of its duties or responsibilities under the Plan.  Any such duties or responsibilities thus allocated must be
described in the written instrument.  If
a person other than an Employee of (PDL) is so designated, such person must
acknowledge acceptance of the allocated duties and responsibilities in
writing.  All such instruments shall be
attached to, and made part of the Plan.

 

4.6                               Delegation of Authority

 

PDL also hereby appoints each group insurance
policy issuer (issuer) listed in Appendix A as a named fiduciary as defined by
ERISA Section 402 (a)(1), with such powers as may be necessary to determine the
benefits payable under the insurance policies and resolve all questions
pertaining to the applicability of the benefit provisions of the insurance
policies.

 

PDL hereby intends that each Issuer shall be
deemed to have compiled with the requirements of ERISA Act Section 503 (claims
procedure) in its exercise of its authority unless it has abused its discretion
hereunder by acting arbitrarily and capriciously.

 

4.7                               Expenses

 

PDL shall pay all expenses authorized and
incurred by the Plan Administrator in the administration of the Plan, unless by
agreement or common practice the Plan Administrator absorbs such expenses.

SECTION V –
HEALTH CLAIM PROCEDURES

 

The procedures  outlined below must be
followed by Covered Persons (“claimants”) to obtain payment of health benefits
under this Plan.

 

5.1                               Health Claims

 

All claims and questions regarding health
claims should be directed to the Contract Administrator.  The Plan Administrator shall have final
authority for adjudicating all claims and a full review of the decision on such
claims in accordance with the following provisions and with the Employee
Retirement Income Security Act of 1974, as amended (“ERISA”).  The Plan Administrator has delegated the
authority to the Contract Administrator subject to the Plan Administrator’s
right to make all final decisions to process claims in accordance with the Plan
Document and Summary Plan Description.

 

Each claimant claiming benefits under the
Plan shall be responsible for supplying, at such times and in such manner as
the Plan Administrator in its sole discretion may require, written proof that
the expenses were incurred or that the benefit is covered under the Plan.  If the Plan Administrator in its sole
discretion shall determine that the claimant has not incurred a covered expense
or that the benefit is not covered under the Plan, or if the claimant has
failed to furnish such proof as is requested, no benefits shall be payable
under the Plan.

 

Under the Plan, there are four types of
claims:  Urgent Pre-service, Non-urgent
pre-service, Concurrent Care and Post-service.

 

Pre-service
Claims:

 

A “Pre-service Claim” is a claim for a
benefit under the Plan where the Plan conditions receipt of the benefit, in
whole or in part, on approval of the benefit in advance of obtaining medical
care.

 

A “Pre-service Urgent Care Claim” is any
claim for medical care or treatment with respect to which the application of
the time periods for making non-urgent care determinations could seriously
jeopardize the life or health of the claimant or the claimant’s ability to
regain maximum function, or, in the opinion of a physician with knowledge of
the claimant’s medical condition, would subject the claimant to severe pain
that cannot be adequately managed without the care or treatment that is the
subject of the claim.

 

It is important to remember that, if a
claimant needs medical care for a condition which could seriously jeopardize
his life, there is no need to contact the Plan for prior approval. The claimant
should obtain such care without delay.

 

Further, if the Plan does not require
the claimant to obtain approval of a medical service prior to getting
treatment, then there is no “Pre-service Claim.”  The claimant simply follows the Plan’s procedures with respect to
any notice which may be required after receipt of treatment, and files the
claim as a Post-service Claim.

 

Concurrent
Claims:

 

A “Concurrent Claim” arises when the Plan has
approved an on-going course of treatment to be provided over a period of time
or number of treatments, and either (a) the Plan determines that the course of
treatment should be reduced or terminated, or (b) the claimant requests
extension of the course of treatment beyond that which the Plan has approved.

 

If the Plan does not require the
claimant to obtain approval of a medical service prior to getting
treatment, then there is no need to contact the Plan Administrator to request
an extension of a

 

7

 

course of treatment.  The claimant simply follows the Plan’s
procedures with respect to any notice which may be required after receipt of
treatment, and files the claim as a Post-service Claim.

 

Post-service
Claims:

 

A “Post-service Claim” is a claim for a
benefit under the Plan after the services have been rendered.

 

5.2                               When
Health Claims Must Be Filed

 

Health claims  must be filed with the
Contract Administrator within 90 days of the date charges for the service were
incurred.  Benefits are based upon the
Plan’s provisions at the time the charges were incurred.  Charges are considered incurred when
treatment or care is given or supplies are provided.  Claims filed later than that
date shall be denied, unless it is shown that it was not reasonably possible to
file within 90 days, but in no event later than twelve (12 months from the date
on which covered charges were incurred.

 

A Pre-service Claim (including a Concurrent
Claim that also is a Pre-service Claim) is considered to be filed when the
request for approval of treatment or services is made and received by the Third
Party Administrator in accordance with the Plan’s procedures.  However, a Post-service Claim is considered
to be filed when the following information is received by the Contract
Administrator, together with a Form HCFA or Form UB92:

 

a.                                       The date of service;

b.                                      The name, address, telephone number and tax
identification number of the provider of the services or supplies;

c.                                       The place where the services were rendered;

d.                                      The diagnosis and procedure codes;

e.                                       The amount of charges;

f.                                         The name of the Plan;

g.                                      The name of the covered employee; and

h.                                      The name of the patient.

 

Upon receipt of this information, the claim
will be deemed to be filed with the Plan. 
The Contract Administrator will determine if enough information has been
submitted to adjudicate the claim.  If
not, the Contract Administrator may request more information.  The Contract Administrator must receive the
additional information within 45 days (48 hours in the case of Pre-service
Urgent Care Claims) from receipt by the claimant of the request for additional
information.  Failure to do so may result in claims being declined or benefits reduced.

 

5.3                               Timing of
Claim Decisions

 

The Plan Administrator shall notify the
claimant, in accordance with the provisions set forth below, of a denial (and,
in the case of Pre-service Claims and Concurrent Claims, of decisions that a
claim is payable in full) within the following timeframes:

 

Pre-service Urgent Care Claims:

 

a.                                       If the claimant has provided all of the
necessary information, as soon as possible, taking into account the medical
exigencies, but not later than 72 hours after receipt of the claim.

b.                                      If the claimant has not provided all of the
information needed to process the claim, then the claimant will be notified as
to what specific information is needed as soon as possible, but not later than
24 hours after receipt of the claim. 
The claimant will be notified of a determination of benefits as soon as
possible, but not later than 48 hours, taking into account the medical
exigencies, after the earliest of (i) the Plan’s receipt of the specified

 

8

 

information, or (ii) the end of the period
afforded the claimant to provide the information.

 

Pre-service
Non-urgent Care Claims:

 

a.                                       If the claimant has provided all of the
information needed to process the claim, in a reasonable period of time
appropriate to the medical circumstances, but not later than 15 days after
receipt of the claim, unless an extension has been requested, then prior to the
end of the 15-day extension period.

 

b.                                      If the claimant has not provided all of the
information needed to process the claim, then the claimant will be notified as
to what specific information is needed as soon as possible, but not later than
5 days after receipt of the claim.  The
claimant will be notified of a determination of benefits in a reasonable period
of time appropriate to the medical circumstances, either prior to the end of
the extension period (if additional information was requested during the
initial processing period), or by the date agreed to by the Plan Administrator
and the claimant (if additional information was requested during the extension
period).

 

Concurrent
Claims:

 

a.                                       Plan Notice of Reduction or
Termination.  If the Plan Administrator
is notifying the claimant of a reduction or termination of a course of
treatment (other than by Plan amendment or termination), before the end of such
period of time or number of treatments. 
The claimant will be notified sufficiently in advance of the reduction
or termination to allow the claimant to appeal and obtain a determination on
review of that adverse benefit determination before the benefit is reduced or
terminated.

 

b.                                      Request by Claimant
Involving Urgent Care.  If the Plan Administrator receives a request
from a claimant to extend the course of treatment beyond the period of time or
number of treatments that is a claim involving Urgent Care, as soon as
possible, taking into account the medical exigencies, but not later than 24
hours after receipt of the claim, as long as the claimant makes the request at
least 24 hours prior to the expiration of the prescribed period of time or
number of treatments.   If the claimant
submits the request with less than 24 hours prior to the expiration of the
prescribed period of time or number of treatments, the request will be treated
as a claim involving Urgent Care and decided within the Urgent Care timeframe.

 

c.                                       Request by Claimant
Involving Non-urgent Care.  If the Plan Administrator receives a request
from the claimant to extend the course of treatment beyond the period of time
or number of treatments that is a claim not involving Urgent Care, the request
will be treated as a new benefit claim and decided within the timeframe
appropriate to the type of claim (either as a Pre-service Non-urgent Claim or a
Post-service Claim).

 

Post-service
Claims:

 

a.                                       If the claimant has provided all of the
information needed to process the claim, in a reasonable period of time, but
not later than 30 days after receipt of the claim, unless an extension has been
requested, then prior to the end of the 15-day extension period.

 

b.                                      If the claimant has not provided all of the
information needed to process the claim and additional information is requested
during the initial processing period, then the claimant will be notified of a
determination of benefits prior to the end of the extension period, unless
additional information is requested during the extension period, then the
claimant will be notified of the determination by a date agreed to by the Plan
Administrator and the claimant.

5.7                               Requirements for Medicaid

 

To the extend required by Section 609 of
ERISA with respect to group health plans, effective August 10, 1993, payment of
benefits with respect to a Participant will be made in accordance with any
assignment of rights made by or on behalf of such Participant as required by a
state plan of medical assistance approved under Title XIX of the Social
Security Act pursuant to Section 1912(a)(1)(A) of such Act (as in effect on the
date of enactment of the Omnibus Budget Reconciliation Act of 1993). In
enrolling a Participant or in determining or making any payments for benefits
for benefits to or on behalf of the Participant, the fact that such Participant
is eligible for or is provided medical assistance under a state plan for
medical assistance under Title XIX of the Social Security Act will not be taken
into account for purposes of this Plan. To the extent that payment has been
made under a state plan for medical assistance approved under Title XIX of the
Social Security Act in any case in which the Plan, after applying the Plan’s
claims filing deadlines and other general procedures, has a legal liability to
make payments for items or services constituting such assistance, payment for
benefits under the Plan will be made in accordance with any state law which
provides that the state has acquired the rights of the Participant to such
payment for such items or services.

Exhibit 10.4    
    

Amendment No. 2 to the Robert Half International Inc.

Restated Retirement Agreement  

        This agreement is effective October 22, 2003, and amends the terms of the Robert Half International Inc. Restated Retirement Agreement (the
"Retirement Agreement') previously entered into between Robert Half International Inc. (the "Company") and Harold M. Messmer, Jr. 

 1.    Section 1(g) of the Retirement Agreement is amended to read as follows:  

        "Covered
Compensation" means (1) $2500 plus (2) one-twelfth of the combination of Salary and Bonus paid to Participant with respect to calendar year 2000. 

 2.    Section 6(b)(1) of the Retirement Agreement is amended, to read as follows:  

        (b)(1)(A)    Upon
termination of Participant's employment, the Company shall purchase and deliver to Participant an annuity to fund the obligations of the Company to
Participant pursuant hereto, as such obligations exist as of the date of termination. The annuity to be purchased shall be determined by obtaining bids from insurance companies that meet the
requirements set forth in the definition of "Current Actuarial Value of the Company's Obligations," and taking into account those bids that would be taken into account if the Company were soliciting
bids to satisfy its funding obligation under subsection (a). For the purpose of determining the specifications for the annuity to be purchased, there shall be applied the modification to the
definition of "Annual Percentage Increase in CPI" described in Section 1(j)(2). The annuity contract to be purchased shall be the middle bid of the bids obtained (if an even number of bids are
obtained, the least expensive bid shall be ignored if an annuity contract is to be purchased). 

        (B)  The
Participant may direct that a portion of the funds that would otherwise be used to purchase the annuity described in (A) be remitted by the Company to satisfy
the tax withholding obligations that would apply to Participant on account of such purchase. In the event of such direction, the funds used to purchase the annuity shall be reduced by the amount
remitted. 

        (C)  Alternatively,
at the request of Participant, the Company shall pay Participant in a lump sum an amount equal to the average of all the bids that are taken into account
under (A). If no annuity bid can be obtained from an insurance company that meets the criteria of Section 1(j)(1)(A) or (B), the Participant shall be paid a lump sum calculated in accordance
with Section 1(j)(1)(E). 

 3.    Subsection (c) is added to §6 of the Retirement Agreement, to read as follows:  

        (c)(1)    Subsection
(b)(1) provides for payment of Participant's retirement obligation by delivery of an insurance company annuity contract or a cash lump sum. In lieu of the
delivery of such insurance company annuity contract or a cash lump sum, Participant shall have the right to choose that all or a portion of his benefit be paid by the Company (the "Company Payment")
upon his termination of employment. Such Company Payment election shall only be effective if it is delivered to the Company in the year prior to Participant's termination of employment and at least
six months prior to such termination. Any election may be modified, except that such modification will only be effective if Participant terminates in the year after such modification and six months or
more after the date of modification. Making the election in this subsection (c) does not modify the application of subsection (b)(3). 

        (2)   The
following paragraphs of this subsection illustrate the manner in which the Company Payment election applies. For purposes of this illustration, assume that
Participant determines that 60% of his monthly benefit shall be payable by the Company. 

        (3)   In
the case of an election to receive 60% of the benefit from the Company, the other 40% of the Participant's benefit shall be payable as set forth in (b) above,
i.e., either by 

distribution
of a cash lump sum or an insurance company annuity contract, except that the calculations under (b) shall be based on 40% of the promised benefit. Subsection (b)(2) shall be
modified, however, so that, the trust described in that subsection shall not terminate; instead, there shall only be withdrawn from the trust an amount equal to the purchase price of the insurance
company annuity contract, or the cash paid to Participant, as the case may be. Notwithstanding the preceding sentence, no amount shall be withdrawn from the trust if the remaining amount in the trust
is less than the Current Actuarial Value of the Company's Obligations (computed with respect to the remaining Company obligation); any difference between what can be withdrawn from the trust and the
amount payable to the Participant shall be paid directly by the Company. The adjustment mechanism of (b)(3) shall continue to apply to the 40% of the Participant's benefit that has been paid under
(b). 

        (4)   The
remaining 60% of the Company's obligations shall be satisfied by monthly payments by the Company to the Participant. After these payments are made by the Company,
the Company shall have the right to be reimbursed annually from the trust within 60 days following each June 30 in an amount equal to such payments to the Participant over the prior
12 months. Furthermore, within 60 days of each June 30, if requested by the Participant, the Company shall make additional payments to the trust, if required, so that the trust is
funded in an amount equal to the Current Actuarial Value of the Company's Obligations, except that the funding obligation shall be computed only with reference to the benefits due under this Agreement
that were not previously satisfied by the distribution of cash or an insurance company annuity contract under (b). 

        (5)   At
any time subsequent to termination of employment Participant may determine that, instead of the Company Payments described in this subsection (c), he wishes to
receive an insurance company annuity contract or cash lump sum in settlement of the remaining value of the Company Payments due with respect to the 60% benefit. To receive the lump sum, Participant
shall deliver a notice to Company requesting such lump sum. Company will thereupon as quickly as practicable (but in no event later than 30 days from the delivery of the notice) compute the
amount to be paid using the methodology set forth in subsection (b) above, and Participant will be given a choice between the receipt of cash or an insurance company annuity contract, as set
forth in subsection (b). Notwithstanding the preceding sentences of this paragraph (5), the amount to be paid Participant will be reduced by 6%. For example, if the lump sum otherwise payable
to Participant were $5,000,000, participant would only receive a lump sum of $4,700,000, and the $300,000 balance would be forfeited to the Company. Subsequent to receipt of an insurance company
annuity contract or a cash lump sum under this paragraph (5), the adjustment mechanism of (b)(3) shall apply to the Company Payments that have been so settled, but applied as if the monthly
payment obligation were 94% of the originally computed amount. Subsequent to settlement under this paragraph, the trust established pursuant to this section shall terminate as described in subsection
(b)(2). 

        (A)  In
addition to the right to receive the entire value of the Company Payment as an insurance company annuity contract or cash lump sum, Participant may elect that a
smaller portion of the Company Payment be payable as an insurance company annuity contract or cash lump sum, in which
case the remaining portion of his Company Payment shall continue to be paid as described in this subsection (c), including the right to settle the remaining portion under this paragraph (5). 

        (6)   The
settlement mechanism in this subsection (c) shall apply in the event of Participant's death prior to termination of employment, except that Participant's
Designated Beneficiary shall have the right to make the decisions that would otherwise be reserved to Participant. In the event that Participant terminates employment and is receiving Company Payments
at his death, the settlement mechanism in this subsection (c) shall apply to his Designated Beneficiary. The option to receive Company Payments rather than a insurance company annuity contract
or a cash lump sum shall only be available if an election is filed by the Designated Beneficiary prior to death no later than the time described in paragraph (1) above. 

        (7)   Instead
of the Company Payments described above, the Participant may elect that the Company pay his benefit in the form of a fixed number of annual installments, to be
paid at the election of the Participant over a number of years selected by the Participant, which number shall be from 2 to 10 years. The installments shall have the same "Actuarial Value" as
the Company Payments described in (1). For this purpose, "Actuarial Value" shall be computed by using (A) the interest assumption specified in Section 417(e)(3) of the Internal Revenue
Code (using the applicable interest rate for the second month preceding the date on which distribution commences), (B) the mortality assumptions specified in Section 417(e)(3) of the
Internal Revenue Code, and (C) the fixed percentage described in Section 1(j)(2) as the CPI assumption. At any time during the period of payout of the installments, the Participant may
make the election described in (5). If such an election is made, the value of the lump sum to be received shall be computed using the interest assumption in this subsection and the 6% discount
described in (5) shall apply. In addition to the installment payments described in this paragraph, the Participant may propose a different form of alternative payment in his notice of election;
the Company at its discretion may determine whether to agree to such different form of alternative payment. 

        Executed
November 13, 2003, and effective October 22, 2003.
