Deferral Commitments

Minimum Deferral. A Participant must defer during each Plan Year of the Deferral
Commitment Period at least one of the following minimum amounts:

(a)
In the case of an Employee, $2,000 of his or her Base Annual Salary; or

(b)
In the case of a Director who is not an Employee, a percentage that is
anticipated to equal $2,000 of his or her Directors Fees.

A Participant shall not be permitted to defer any portion of his or her Annual
Bonus unless he or she meets one of the minimum Deferral requirements set forth
in this Section. If a Participant first becomes a Participant after the first
day of a Plan Year, or in the case of the first Plan Year of the Plan itself, at
the election of the Employee on the Election Form, the minimum deferral
described in (a) shall be an amount equal to $2,000, multiplied by a fraction,
the numerator of which is the number of complete months remaining in the Plan
Year and the denominator of which is 12.

3.2
Maximum Deferral. For each Plan Year of the Deferral Commitment Period, a
Participant may defer up to fifty percent (50%) of his or her Base Annual
Salary, fifty percent (50%) of his or her Annual Bonus (except as noted in

In no event shall an annual deferral amount be decreased during the Deferral
Commitment Period. An annual deferral amount may only be increased (i) prior to
the commencement of the Plan Year to which such annual deferral amount relates
and (ii) with the approval of the Committee.

3.4
Deferral Commitment Period. The "Deferral Commitment Period" for each
Participant shall be a fixed period of four (4) consecutive Plan Years
commencing with the 1991 Plan Year unless otherwise designated by the Committee.

3.5
Withholding of Deferral Amounts. The portion of the Base Annual Salary elected
to be deferred annually shall be withheld in equal amounts over the Plan Year.
The portion of Annual Bonus and Directors Fees being deferred shall be withheld
at the time the Annual Bonus or Directors Fees would otherwise be paid to the
Participant. Notwithstanding the above, for such first Plan Year, Participants
can elect to:

(a)
Defer the total Base Annual Salary deferral in that first Plan Year,

(b)
Defer an amount equal to the amount in Article 3.5(a) above multiplied by a
fraction, the numerator of which is the number of complete months remaining in
the first Plan Year, and the denominator of which is twelve (12).

6

--------------------------------------------------------------------------------

Exhibit 10.5

(c)
Defer from Base Annual Salary an amount equal to Article 3.5(b), above. In
addition, the difference between Articles 3.5(a) and 3.5(b) would be deferred
from the Annual Bonus for the first Plan Year (in addition to any Annual Bonus
election). For the first Plan Year only, the total Annual Bonus deferral could
exceed fifty percent (50%) by nature of this provision.

3.6
FICA Taxes. For each Plan Year of the Deferral Commitment Period, the Employer
shall ratably withhold from that portion of the Participant's Base Annual Salary
and/or Annual Bonus that is not being deferred, the Participant's share of FICA
taxes based on an amount equal to the Base Annual Salary and/or Annual Bonus
before reduction by the amount deferred. If necessary, the Committee shall
reduce the amount deferred in order to comply with this Section 3.6.

3.7
Interest Crediting Prior to Distribution.

(a)
Except as provided in Section 3.7(b) and Section 3.7(c) below, interest shall be
credited annually on a Participant's Account Balance at 125% of the Moody's
Rate. For purposes of this crediting, all amounts deferred during a Plan Year
shall be treated as having been deferred as of the beginning of the Plan Year.
Such interest crediting shall be made up to the date of the Pre-Retirement
Distribution, the Retirement Date, the date of the Participant's death or the
date of Termination of Employment, depending on whether the benefit is paid
under Article 4, 5, 6 or 7, respectively.

(b)
In the event of a Termination of Employment, interest shall be credited in the
manner provided in Section 3.7(a), but at the rate provided for in Section 7.2.

(c)
In the event of a Participant's suicide, interest shall be credited in
accordance with Section 6.4.

3.8
Hardship.

(a)
If a Participant experiences an Unforeseeable Financial Emergency as described
in Section 3.8(b) below, the Participant may petition the Committee to (i)
suspend any deferrals required by the Plan Agreement and/or (ii) receive a
distribution from the Plan. Any approval of such a petition shall be made at the
sole discretion of the Committee. If the Committee approves a distribution, the
distribution shall be made within sixty (60) days of the date of approval. The
distribution may not exceed the Participant's Account Balance as of the last day
of the month prior to the date of the Committee's approval of the petition,
calculated as if such Participant were receiving a Termination Benefit as of
such date.

(b)
An "Unforeseeable Financial Emergency" shall mean an unexpected need for cash
arising from an illness, casualty loss, sudden financial reversal, transfer of
place of employment or other such unforeseeable occurrence, all as determined in
the sole discretion of the Committee.

Article 4
Pre-Retirement Distribution

4.1
Eligibility for Pre-Retirement Distribution. A Participant may elect to receive
a Pre-Retirement Distribution from the Plan to be received in or after the
eighth Participation Year. This election shall be irrevocable and shall be made

the commencement of the Deferral Commitment Period.

4.2
Amount of Distribution. The amount of the Pre-Retirement Distribution shall be
any amount not to exceed the electing Participant's Account Balance at the end
of the Participation Year prior to the Participation Year selected on the
Election Form for the distribution. The Pre-Retirement Distribution may not be
made prior to the eighth (8th) Participation Year. At the election of the
Participant (on the Election Form), this amount shall be distributed or, in the
case of installment payments, shall start distribution within ninety (90) days
of the January 1st of the Participation Year selected on the Election Form in
one of the following manners:

(a)

Year prior to the Participation Year selected on the Election Form for the
distribution; or

In a lump sum equal to a fixed dollar amount. Such fixed dollar amount shall be
chosen by the Participant on the Election Form. Any remaining amounts in the
Account Balance, after completion of the Pre-Retirement Distribution, shall
remain in the Plan to be paid under the other provisions of the Plan; or

Distribution, shall remain in the Plan to be paid under the other provisions of
the Plan; or

(d)
In four or fewer annual consecutive installments so that the total Account
Balance is completely distributed over the elected installment period. Interest
on the unpaid Account Balance shall be credited at 125% of Moody's.

If the amount of Pre-Retirement Distribution elected by the Participant exceeds
the total Account Balance at any time during the Pre-Retirement Distribution
period, only the amount remaining in the Account Balance shall be distributed to
the Participant and the Employer shall have no further liability under the Plan.

Article 5

5.1
Eligibility for Retirement Benefit. If the Participant ceases to be an Employee
or a Director for any reason other than death, including without limitation,

5.2

Date and in the case of installment payments, shall continue until the
Retirement Benefit is paid in full.

5.3
Retirement Benefit - Amount. If the Retirement Benefit is paid in a lump sum, it
shall be the retired Participant's Account Balance determined as of the
Retirement Distribution Date. If the Retirement Benefit is paid in installments,
it shall be a constant monthly payment, determined at the beginning of each Plan
Year by monthly amortization of the remaining Account Balance over the remaining
payment period. Interest on the unpaid balance will be credited for the
remaining periods at 125% of the Moody's Rate established for each of the
subsequent Plan Years.

5.4
Death Prior to Completion of Retirement Benefit. If the Participant dies after
the Retirement Date and prior to the completion of the Retirement Benefit
payments, the retired Participant's designated Beneficiary will receive any
unpaid Retirement Benefit payments due the Participant, either at the times they
were to be received by the Participant, or in a lump sum, as determined by the
Committee in its sole discretion. If this Section 5.4 applies, a designated
Beneficiary shall not be entitled to any benefits provided for under Article 6.

Article 6
Survivor Benefit

6.1
Eligibility for Survivor's Benefit. If a Participant dies before the Retirement
Date and before Termination of Employment, the Employer shall pay the Survivor's
Benefit to the deceased Participant's Beneficiary, provided that all of the
following conditions are met:

(a)
the Participant's death was determined not to be from a bodily or mental cause
or causes, the information about which was withheld, knowingly concealed, or
falsely provided by the Participant, when requested by the Employer to furnish
evidence of good health; and

(b)
proof of the Participant's death is furnished to the Committee in such form as
determined acceptable by the Committee.

6.2
Survivor's Benefit - Method of Payment. The Survivor's Benefit may be paid in a
lump sum, or in installments over a period of 60, 120, or 180 months at the sole
discretion of the Committee. The lump sum payment shall be made, or installment
payments shall commence within sixty (60) days of the date the Participant died
and in the case of installment payments, shall continue until the Survivor's
Benefit is paid in full.

6.3
Survivor's Benefit - Amount. If the Survivor's Benefit is paid in a lump sum, it
shall be the retired Participant's Account Balance determined as of the date the
Participant died. If the Survivor's Benefit is paid in installments, it shall be
a constant monthly payment, determined at the beginning of each Plan Year by
monthly amortization of the remaining

8

--------------------------------------------------------------------------------

Exhibit 10.5

Account Balance over the remaining payment period. Interest on the unpaid
balance will be credited for the remaining periods at 125% of the Moody's Rate
established for each of the subsequent Plan Years.

6.4
Suicide. In the event of a Participant's suicide within twenty-four months of
the first deferral of any Deferral Commitment Period, the Employer shall be

portion of the Deferral Amount, without interest, and no other Survivor's
Benefit shall be payable.

Article 7
Termination Benefit

7.1
Eligibility for Termination Benefit. If a Participant experiences a Termination
of Employment prior to the Retirement Date, the Employer shall pay to the
Participant the Termination Benefit.

7.2
Termination Benefit. The Termination Benefit is a sum equal to the Participant's
Account Balance determined as provided in this Section 7.2, as of the date of
Termination of Employment, and shall be paid in a lump sum within ninety (90)
days following the Termination of Employment. In determining the Account Balance
for purposes of this Article 7 only, interest shall be calculated in the manner
provided in Section 3.7(a) above, but using the applicable interest rate set
forth in the following schedules:

Number of Participation Years
 
Interest Crediting Rate
 
 
 
For Employees:
 
 
Less than 2 years

In the event a Participant is both an Employee and Director, interest shall be
credited under the Employee schedule.

Article 8
Disability

8.1
Eligibility for Disability Waiver. If a Participant suffers a Disability during
any Plan Year during the Deferral Commitment Period, the Participant's annual
deferral amount for that Plan Year or any subsequent Plan Year shall, except as
provided in this Section 8.1, be as set forth in his or her Election Form for
the first six (6) months that a Participant suffers from a Disability, and the
withholding of the Participant's monthly deferral amounts, calculated in
accordance with Section 3.5, shall be met from the Participant's taxable portion
of the disability benefit under the Employer's long-term disability program.
Should the monthly deferral amount exceed one hundred percent (100%) of the
taxable disability benefit, the Participant's deferral obligation shall be
excused to the extent of that excess. If a Participant's Disability exceeds six
(6) consecutive months, the Participant shall be excused from making any
additional deferrals while he or she is suffering from a Disability.

8.2
Benefits. A Participant suffering a Disability, but not terminated as a result
of long-term disability under the Employer's policies and practices, shall
continue to be considered a Participant and shall be eligible for the benefits
provided for in Articles 4, 5, 6 or 7 in accordance with the provisions of those
Articles.

8.3
Long-Term Disability - Termination. For a Participant who is terminated as a
result of disability under the Employer's policies and practices, the provisions
of Article 5 shall apply for purposes of Account Balance distribution and
interest crediting.

9

--------------------------------------------------------------------------------

Exhibit 10.5

Article 9
Beneficiary

9.1
Beneficiary. Each Participant shall have the right, at any time, to designate
any person or persons as his or her Beneficiary or Beneficiaries (both primary
as well as contingent) to receive any benefits payable under the Plan to a
Beneficiary upon the death of a Participant.

9.2
Beneficiary Designation; Change. A Participant shall designate his or her
Beneficiary or Beneficiaries by completing and signing the Beneficiary
Designation Form, and returning it to the Committee. A Participant shall have
the right to change a Beneficiary by completing, signing and otherwise complying
with the terms of the Beneficiary Designation Form.

9.3
Acknowledgment. No designation or change in designation of a Beneficiary shall
be effective until received, accepted and acknowledged in writing by the
Committee.

9.4
No Beneficiary Designation. If a Participant fails to designate a Beneficiary as
provided above, or if all designated Beneficiaries predecease the Participant or
die prior to complete distribution of the Participant's benefits, then the
Participant's designated Beneficiary shall be deemed to be his or her surviving
spouse. If the Participant has no surviving spouse, the benefits remaining under
the Plan to be paid to a Beneficiary shall be payable to the executor or
personal representative of the Participant's estate.

9.5
Doubt as to Beneficiary. If the Committee has any doubt as to the proper
Beneficiary to receive payments pursuant to this Plan, they shall have the right
to withhold such payments until this matter is resolved to their satisfaction.

9.6
Discharge of Obligations. The payment of benefits under the Plan to a
Beneficiary shall fully and completely discharge the Employer from all further
obligations under this Plan with respect to the deceased Participant and all of
his or her Beneficiaries.

Article 10
Leave of Absence

10.1
Authorized Leave of Absence. If a Participant is authorized by the Employer for
any reason to take a paid leave of absence from employment, such Participant
shall continue to be considered employed as an Employee or Director and shall be
required to maintain the level of deferrals set forth in his or her Plan
Agreement in order to keep the Plan Agreement in full force and effect. If such
leave of absence is unpaid, the Participant shall continue to be considered
employed as an Employee or Director and will be excused from making deferrals
until the unpaid leave of absence ends; provided, however, that if the unpaid
leave of absence continues beyond three consecutive months, the Participant
shall be treated as having incurred a Termination of Employment as of the end of
such three month period and the Participant shall receive the Termination
Benefit in accordance with Article 7. In the case of a conflict between this
Article 10 and Article 8, Article 8 shall prevail.

Article 11
Employer/Participant Liability

11.1
General Assets. Amounts payable to a Participant shall be paid from the general
assets of the Employer exclusively.

11.2
Employer's Liability. The Employer's liability for the payment of benefits shall
be defined only by this Plan, as entered into between the Employer and a
Participant.

11.3
Limitation of Obligation. The Employer shall have no obligation to a Participant
under the Plan, except as expressly provided for in the Plan.

11.4
Participant Cooperation. The Participant must cooperate with the Employer and
the Committee in furnishing all information requested by the Employer and/or
Committee in order to facilitate the payment of benefits, and the administration
and operations of this Plan. Such information may include taking a physical
examination, or other actions, and such cooperation shall extend beyond the
termination of the Plan Agreement and the Employee's Participation in the Plan.

11.5
Unsecured General Creditor. Participants, their Beneficiaries and their
permitted heirs, successors and assigns shall have no legal or equitable rights,
interest or claims in any property or assets of the Employer. Any and all of the
Employer's

10

--------------------------------------------------------------------------------

Exhibit 10.5

assets shall be, and remain, the general, unpledged unrestricted assets of the
Employer. The Employer's obligations under the Plan shall be merely that of an
unfunded and unsecured promise of the Employer to pay money in the future.

Article 12
No Guarantee of Employment

12.1
No Guarantee of Employment. Nothing in this Agreement shall be construed as
altering in any manner the employment relationship with an Employee or Director,
which is hereby acknowledged to be an "at will" employment relationship that can
be terminated at any time for any reason, with or without cause, unless
otherwise expressly provided in a written employment agreement. All terms and
conditions of an Employee's or Director's current employment shall remain the
same. Nothing in this Plan creates, or is meant to create, any obligation on the
part of the Employer to keep an Employee or Director employed by the Employer or
not to terminate an Employee or Director at any time and for any reason.

Article 13
Termination, Amendment or Modification of the Plan

13.1
Termination. The Company reserves the right to terminate the Plan at any time.
Upon termination of the Plan, the Participant's Account Balance shall be paid
out in accordance with the benefits that the Participant would receive if there
had occurred a Termination of Employment with respect to the Participant on the
date of Plan termination or, if such termination occurs after the Retirement
Date, the Participant had retired on the date of Plan termination.
Notwithstanding the above, the termination of the Plan shall not affect any
Participant or Beneficiary who has become entitled to the payment of benefits
under the Plan as of the date of termination.

13.2
Amendment. The Company may, at any time, amend or modify the Plan in whole or in
part, provided, however, that no amendment or modification shall be effective to
decrease or restrict a Participant's Account Balance in existence at the time
the amendment or modification is made, calculated as if there had occurred a
Termination of Employment with respect to such Participant as of the effective
date of the amendment or, if such amendment occurs after the Retirement Date,
the Participant had retired as of the effective date of the amendment. The
amendment or modification of the Plan shall not affect any Participant or
Beneficiary who has become entitled to the payment of benefits under the Plan as
of the date of the amendment or modification.

13.3
Termination of Plan Agreement. Absent the earlier termination, modification or
amendment of the Plan, the Plan Agreement of any Participant shall terminate
upon the full payment of the applicable benefit provided under Articles 4, 5, 6,
or 7, as the case may be.

13.4
Change in Control.

(a)
All benefits accrued under the Plan as of the date of a Change of Control shall
thereafter be paid in accordance with the terms and conditions of this Plan.
However, if at any time during a period of three years following a Change of
Control of the Company, the employment of a participant by the Employer is
terminated (i) by the Employer for any reason other than for Cause, or (ii) by
the Participant for just reason, then all benefits, including all interest at
the full 125% of Moody's rate shall apply and not at the rates applicable in
Section 7.2. Such amounts will thereupon be immediately due and payable in full,
less any withholdings required by law, to such Participant, and within ten
business days thereafter the Employer, or any successor corporation of the
Employer shall deliver payment of such Account Balance to such Participant.

A Participant shall be deemed to have terminated his or her employment for just
reason if he or she resigns voluntarily after a demotion, a material reduction
in his or her authority or responsibility or any reduction in his or her
compensation or after being notified of a relocation of his or her work place
that would materially increase the commuting distance from his or her then
current principal residence.

A Participant shall be deemed to have been terminated by the Employer for cause
only if such participant has been terminated by reason of (i) a willful failure
by such Participant to substantially perform his or her duties other than a
failure resulting from the Participant's incapacity due to physical or mental
illness, or (ii) a willful act by the Participant that constitutes gross
misconduct and is materially injurious to the Employer. No act or failure to act
by a Participant shall be considered "willful" unless committed without good
faith and without a reasonable belief that the act of omission was in the best
interests of the Employer.

11

--------------------------------------------------------------------------------

Exhibit 10.5

(b)
As used in this Plan, "Change of Control" means the occurrence of any of the
following events:

(i)
Any "person" (as such term is used in Sections 13(d) and 14(d) of the Securities
Exchange Act of 1934, hereinafter "Person") becomes the beneficial owner,
directly or indirectly, of securities of the Company representing twenty-five
percent (25%) or more of the combined voting power of the Company's then
outstanding securities ordinarily (and apart from rights accruing under special
circumstances) having the right to vote at elections of directors;

(ii)
A change in the composition of the Board as a result of which fewer than
two-thirds (2/3rds) of the incumbent directors are Continuing Directors; or

(iii)
A change of control that would be required to be reported in a proxy statement
pursuant to Item 5(f) of Schedule 14A of Regulation 14A under the Securities
Exchange Act of 1934.

An individual shall be considered a "Continuing Director" on a particular date
if he or she either (i) had been a member of the Board twenty-four (24) months
prior to such date or (ii) was elected, or nominated for election, to the Board
with the affirmative votes of at least a majority of the members of the Board
twenty-four

(24) months prior to such date and who were still in office at the time of the
election or nomination.

13.5
Termination, Modification or Amendment Following Change in Control.

Following a Change in Control, neither the Company, any subsidiary of the
Company nor any corporation, trust or other Person that succeeds to all or any
substantial portion of the assets of the Company shall have the right to
terminate, modify, or amend a Plan Agreement in effect prior to such Change in
Control, and all benefits under such Plan Agreement shall thereafter be paid in
accordance with the terms of such Plan Agreement as in effect immediately prior
to such Change in Control. Any provision of this Plan to the contrary shall be
construed in accordance with this Section 13.5.

13.6
Legal Fees To Enforce Rights After Change in Control.

The Company is aware that upon the occurrence of a Change in Control, the Board
(which might then be composed of new members) or a shareholder of the Company or
of any successor corporation might then cause or attempt to cause the Company or
such successor to refuse to comply with its obligations under the Plan and might
cause or attempt to cause the Company to institute, or may institute, litigation
seeking to deny Participants the benefits intended under the Plan. In these
circumstances, the purpose of the Plan could be frustrated. It is the intent of
the Company that Participants not be required to incur the expenses associated
with the enforcement of their rights under the Plan by litigation or other legal
action, because the cost and expense thereof would substantially detract from
the benefits intended to be extended to Participants hereunder, and that
Participants not be bound to negotiate any settlement of their rights under the
Plan under threat of incurring such expenses. Accordingly, if, following a
Change in Control, it should appear to any Participant that the Company has
failed to comply with any of its obligations under the Plan or any agreement
thereunder or, if the Company or any other Person takes any action to declare
the Plan or any agreement hereunder void or unenforceable or institutes any
litigation or other legal action designed to deny, diminish or to recover from
any Participant the benefits intended to be provided to each Participant under
the Plan, and such Participant has substantially complied with all of his or her
obligations under the Plan and any such agreement, then the Company irrevocably
authorizes such Participant from time to time to retain counsel of his or her
choice at the expense of the Company to represent such Participant in connection
with the initiation or defense of any litigation or other legal action, whether
by or against the Company or any director, officer, shareholder or other person
affiliated with the Company or any successor thereto in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to each Participant's
entering into an attorney-client relationship with such counsel, and in that
connection the Company and each Participant agree that a confidential
relationship shall exist between each such Participant and his counsel. The
Company shall pay or reimburse each Participant for all reasonable fees and
expenses of counsel selected by such Participant from time to time on a regular,
periodic basis from presentation of a statement or statements prepared by such
counsel in accordance with its customary practices up to a maximum aggregate
amount of $500,000.

13.7
Vesting. Notwithstanding anything that may be construed to the contrary in this
Plan, a Participant shall at all times be 100% vested in his or her Deferral
Amount.

Article 14
Other Benefits and Agreements

14.1
Coordination with Other Benefits. The benefits provided for a Participant and
Participant's Beneficiary under the Plan are in addition to any other benefits
available to such Participant under any other plan or program for employees of
the Employer. The Plan shall supplement and shall not supersede, modify or amend
any other such plan or program except as may otherwise be expressly provided.

Article 15
Restrictions on Alienation of Benefits

15.1
Nonassignability. Neither a Participant nor any other person shall have any
right to commute, sell, assign, transfer, pledge, anticipate, mortgage or
otherwise encumber, transfer, hypothecate or convey in advance of actual
receipt, the amounts if any, payable hereunder, or any part thereof. No part of
the amounts payable shall, prior to actual payment, be subject to any claims of
creditors and, in particular, they shall not be subject to attachment,
garnishment, seizure or sequestration by any creditor for the payment of any
debts, judgments, obligations, alimony or separate maintenance owed by a
Participant.

Article 16
Administration of the Plan

16.1

construction and interpretation thereof, shall be the responsibility of the

Committee Authority. Subject to the Plan, the Committee shall from time to time

Committee's decisions shall be conclusive and binding upon all persons having or
claiming to have any right or interest under the Plan.

16.3
Committee Indemnity. No member of the Committee shall be liable for any act or
omission of any other member of the Committee, nor for any act or omission on
his own part, excepting his or her own willful misconduct. The Employer shall
indemnify and save harmless each member of the Committee against any and all
expenses and liabilities arising out of his or her membership on the Committee,
with the exception of expenses and liabilities arising out of his or her own
willful misconduct.

16.4
Employer's Obligations to the Committee. To enable the Committee to perform its
functions, each Employer shall supply full and timely information to the
Committee on all matters relating to the compensation of all Participants, their
retirement, death, Disability or Termination of Employment, and such other
pertinent facts as the Committee may require.

16.5
Committee Discretion in Payment Schedule. The Committee shall also have the
power, at its sole discretion, to change the manner and timing of payments to be

Beneficiary.

Article 17

(such Participant or Beneficiary being referred to below as a "Claimant") may

Balance, or (ii) distributable to such Claimant from the Plan. If such a claim

require additional time, in which case the Committee's decision must be rendered
within 120 days after such date. Such decision must be written in a manner
calculated to be understood by the Claimant, and it must contain:

(a)
specific reasons for the decision;

future liabilities created with respect to the Deferral Amounts and interest
credits for that year.

18.2
Interrelationship of the Plan and the Trust. The provisions of the Plan and the
Plan Agreement shall govern the rights of a Participant to receive distributions
pursuant to the Plan. The provisions of the Trust shall govern the rights of the
Employer, Participant and the creditors of the Employer to the assets
transferred to the Trust. The Employer shall at all times remain liable to carry
