                                  PARTICIPATION

      3.1 Eligibility.

      An Eligible Employee may participate in the Plan if immediately after the
applicable Offering Date, that Employee would not be deemed for purposes of
Section 423(b)(3) of the Code to possess 5% or more of the total combined voting
power or value of all classes of stock of the Company or any Subsidiary.

      3.2 Election to Participate; Payroll Deductions.

      (a) An Eligible Employee may participate in the Plan only by means of
payroll deduction. An Eligible Employee may elect to participate in the Plan
during an Offering Period by delivering to the Company a written payroll
deduction authorization on a form prescribed by the Company prior to the
applicable Option Date.

      (b) Each person who, during the course of an Offering Period, first
becomes an Eligible Employee will be eligible to become a Participant in the
Plan on the first Offering Date following the day on which such person becomes
an Eligible Employee. Such person may become a Participant in the Plan by
delivering to the Company a written payroll deduction authorization on a form
prescribed by the Company prior to any applicable Offering Date. An individual
who becomes an Eligible Employee after the Offering Date on which an Offering
Period commences, may elect to participate in the Plan on any subsequent
Offering Date provided such Eligible Employee is still an Eligible Employee on
such date.

      (c) A Participant shall automatically participate in the next Offering
Period commencing immediately after the Exercise Date of each Offering Period
provided that such Participant remains an Eligible Employee on the Offering Date
of the new Offering Period and has not withdrawn from the Plan pursuant to
Section 7.1. A Participant who automatically participates in a subsequent
Offering Period, as provided in this Section, is not required to deliver an
additional payroll deduction authorization to continue participation. However, a
Participant may deliver a new payroll deduction authorization on a form
prescribed by the Company if the Participant desires to change any of the
elections contained in the Participant's then effective authorization.

      (d) Except as otherwise provided herein, the amount to be deducted under
the Plan from a Participant's Compensation on each payday during an Offering
Period shall be

                                     - 3 -
<PAGE>

determined by the Participant's payroll deduction authorization, which shall set
forth the percentage of the Participant's Compensation to be deducted on each
payday during the Offering Period. Payroll deductions (i) shall be equal to at
least one percent (1%), but not more than twenty percent (20%), of the
Participant's Compensation as of the Offering Date; (ii) must equal at least
five dollars ($5.00) per pay period; and (iii) may be expressed either as (A) a
whole number percentage or (B) a fixed dollar amount, subject to the provisions
of Sections 5.2 and 5.3 below. Amounts deducted from a Participant's
Compensation pursuant to this Section 3.2 shall be credited to the Participant's
Plan Account.

      (e) Payroll deductions shall commence on the first payday following the
Offering Date and shall continue, unless sooner altered or terminated as
provided herein, to (i) the last payday immediately prior to the end of the
Offering Period or (ii) if the last payday coincides with the last day of the
Offering Period, on the last day of the Offering Period.

      (f) During an Offering Period, a Participant may elect to increase or
decrease the rate of or to stop deductions from his or her Compensation by
delivering to the Company's designated office an amended payroll deduction
authorization. A Participant who elects to decrease the rate of his or her
payroll deductions to zero percent (0%) shall nevertheless remain a Participant
in the current Offering Period unless such Participant withdraws from the Plan
as provided in Section 6.1.

      (g) The Company, in its sole discretion, may suspend a Participant's
payroll deductions under the Plan as the Company deems advisable to avoid
accumulating payroll deductions in excess of the amount that could reasonably be
anticipated to purchase the maximum number of shares of Common Stock permitted
during a calendar year under the limit set forth in Section 4.3. Payroll
deductions shall be resumed at the rate specified in the Participant's then
effective payroll deduction authorization at the beginning of the next Offering
Period, the Exercise Date of which falls in the following calendar year.

      (h) Individual bookkeeping accounts shall be maintained for each
Participant. All payroll deductions from a Participant's Compensation shall be
credited to such Participant's Plan Account and shall be deposited with the
general funds of the Company. All payroll deductions received or held by the
Company may be used by the Company for any corporate purpose.

      3.3 Leave of Absence.

      During paid leaves of absence approved by the Company meeting the
requirements of Regulation Section 1.421-7(h)(2) under the Code, a Participant
may continue participation in the Plan. A participant on an unpaid leave of
absence will not be permitted to make contributions to the Plan by making cash
payments to the Company.

                                  ARTICLE IV.

                               PURCHASE OF SHARES

      4.1 Purchase Price.

      The Purchase Price per share of the Common Stock sold to Participants
hereunder shall be 85% of the Fair Market Value of such share on the Exercise
Date, but in no event shall the Purchase Price per share be less than the par
value per share ($0.01) of the Common Stock.

      4.2 Purchase of Shares.

      (a) On each Exercise Date on which he or she is employed, each Participant
will automatically and without any action on his or her part be deemed to have
exercised his or her option to purchase at the Purchase Price the largest number
of whole shares of Common Stock which can be purchased with the amount in the
Participant's Plan Account. The balance, if any, remaining in the Participant's
Plan Account (after exercise of his or her option) as of an Exercise Date shall
be carried forward to the next Offering Period, unless the Participant has
elected to withdraw from the Plan pursuant to Section 6.1 below. The Board, at
its sole discretion, may increase or decrease the maximum number of shares of
Common Stock that may be purchased during an Offering Period.

      (b) As soon as practicable following each Exercise Date, the number of
shares purchased by such Participant pursuant to subsection (a) above will be
delivered, in the Company's sole discretion, to either (i) the Participant or
(ii) an account established in the Participant's name at a stock brokerage or
other financial services firm designated by the Company. In the event the
Company is required to obtain from any commission or agency authority to issue
any such shares of Common Stock, the Company will seek to obtain such authority.
Inability of the Company to obtain from any such commission or agency authority
which counsel for the Company deems necessary for the lawful issuance of any
such shares shall relieve the Company from liability to any Participant except
to refund to him or her the amount withheld.

      4.3 Limitations on Purchase.

      No Employee shall be granted an option under the Plan which permits his or
her rights to purchase Common Stock under the Plan or any other employee stock
purchase plan of the Company or any of its Subsidiaries to accrue at a rate
which exceeds $25,000 (as measured by the Fair Market Value of such Common Stock
at the time the option is granted) for each calendar year such option is
outstanding. For purposes of this Section 4.3, the right to purchase Common
Stock under an option accrues when the option (or any portion thereof) becomes
exercisable, and the right to purchase Common Stock which has accrued under one
option under the Plan may not be carried over to any other option. In addition,
no Participant shall be permitted to purchase during each Offering Period more
than 10,000 shares of Common Stock (subject to any adjustment pursuant to
Section 5.2).

                                     - 5 -
<PAGE>

      4.4 Transferability of Rights.

      An option granted under the Plan shall not be transferable and is
exercisable only by the Participant. No option or interest or right to the
option shall be available to pay off any debts, contracts or engagements of the
Participant or his or her successors in interest or shall be subject to
disposition by pledge, encumbrance, assignment or any other means whether such
disposition be voluntary or involuntary or by operation of law by judgment,
levy, attachment, garnishment or any other legal or equitable proceedings
(including bankruptcy), and any attempt at disposition of the option shall have
no effect.

      4.5 Pro Rata Allocation of Shares.

      In the event that the number of shares of stock which might be purchased
by all Participants in the Plan on an Exercise Date exceeds the number of shares
of Common Stock available in the Plan as provided in Section 5.1, the Company
shall make a pro rata allocation of the remaining shares in as uniform a manner
as shall be practicable and as the Company shall determine to be equitable. Any
fractional share resulting from such pro rata allocation to any Participant
shall be disregarded.

      4.6 Return of Cash Balance.

      Any cash balance remaining in a Participant's Plan Account following the
close of an Offering Period shall be refunded to the Participant as soon as
practicable after such Offering Period. However, if the cash to be returned to a
Participant pursuant to the preceding sentence is an amount less than the amount
that would have been necessary to purchase an additional whole share of Common
Stock on the Exercise Date, the Company may retain such amount in the
Participant's Plan Account to be applied toward the purchase of shares of Common
Stock in the subsequent Offering Period.

                                   ARTICLE V.

                       PROVISIONS RELATING TO COMMON STOCK

      5.1 Common Stock Reserved.

      Subject to adjustment as provided in Section 5.2, the maximum number of
shares of Common Stock that shall be made available for sale under this Plan
shall be 1,500,000. Shares of Common Stock made available for sale under this
Plan may be authorized but unissued or reacquired shares reserved for issuance
under this Plan. If any option granted under the Plan shall for any reason
terminate without having been exercised, the Common Stock not purchased under
such right shall again become available for issuance under the Plan.

      5.2 Adjustment for Changes in Common Stock.

      In the event that adjustments are made in the number of outstanding shares
of Common Stock or the shares are exchanged for a different class of stock of
the Company by reason of stock dividend, stock split or other subdivision, the
Committee may make appropriate

                                     - 6 -
<PAGE>

adjustments in (a) the number and class of shares or other securities that may
be reserved for purchase hereunder and (b) the Purchase Price of outstanding
options.

      5.3 Merger, Acquisition or Liquidation.

      In the event of the merger or consolidation of the Company into another
corporation, the acquisition by another corporation of all or substantially all
of the Company's assets or 80% or more of the Company's then outstanding voting
stock or the liquidation or dissolution of the Company, the date of exercise
with respect to outstanding options shall be the business day immediately
preceding the effective date of such merger, consolidation, acquisition,
liquidation or dissolution unless the Committee shall, in its sole discretion,
provide for the assumption or substitution of such options in a manner complying
with Section 424(a) of the Code.

      5.4 Insufficient Shares.

      If the aggregate funds available for the purchase of Common Stock on any
Exercise Date would cause an issuance of shares in excess of the number provided
for in Section 5.1 above, (a) the Committee shall proportionately reduce the
number of shares that would otherwise be purchased by each Participant in order
to eliminate such excess, and (b) the Plan shall automatically terminate
immediately after such Exercise Date.

      5.5 Rights as Stockholders.

      With respect to shares of Common Stock subject to an option, a Participant
shall not be deemed to be a stockholder and shall not have any of the rights or
privileges of a stockholder. A Participant shall have the rights and privileges
of a stockholder when, but not until, a certificate has been issued to him or
her following exercise of his or her option.

                                  ARTICLE VI.

                          TERMINATION OF PARTICIPATION

      6.1 Cessation of Contributions; Voluntary Withdrawal.

      (a) A Participant may cease payroll deductions during an Offering Period
by delivering written notice of such cessation to the Company in the manner
prescribed by the Company. Upon any such cessation, the Participant may elect
either to withdraw from the Plan pursuant to Section 6.1(b) or to have amounts
credited to his or her Plan Account held in the Plan for the purchase of Common
Stock pursuant to Section 4.2. A Participant who ceases contributions to the
Plan during any Offering Period shall not be permitted to resume contributions
to the Plan during that Offering Period.

      (b) A Participant may withdraw from the Plan at any time by written notice
to the Secretary of the Company prior to the close of business on an Exercise
Date or such earlier date as may be established by the Committee in its sole
discretion. Within 21 days after the notice of withdrawal is delivered, the
Company shall refund the entire amount, if any, in a Participant's Plan Account
to him or her, at which time, the Participant's payroll deduction authorization,
his or her interest in the Plan and his or her option under the Plan shall
terminate. Any Eligible

                                     - 7 -
<PAGE>

Employee who withdraws from the Plan may again become a Participant in
accordance with Section 3.2 above.

      6.2 Termination of Eligibility.

      (a) If a Participant ceases to be eligible under Section 3.1 above for any
reason, the amount in such Participant's Plan Account will be refunded to the
Participant or his or her designated beneficiary or estate within 21 days of his
or her termination of employment or other cessation of eligibility.

      (b) Upon payment by the Company to the Participant or his or her
beneficiary or estate of the remaining balance, if any, in Participant's Plan
Account, the Participant's interest in the Plan and the Participant's option
under the Plan shall terminate.

                                  ARTICLE VII.

                               GENERAL PROVISIONS

      7.1 Condition of Employment.

      Neither the creation of the Plan nor an Employee's participation therein
shall be deemed to create a contract of employment, any right of continued
employment or in any way affect the right of the Company or a Designated
Subsidiary to terminate an Employee at any time with or without cause.

      7.2 Amendment of the Plan.

      (a) The Board may amend, suspend or terminate the Plan at any time and
from time to time; provided, however, that without approval of the Company's
stockholders given within 12 months before or after action by the Board, the
Plan may not be amended to increase the maximum number of shares subject to the
Plan or change the designation or class of Eligible Employees.

      (b) Upon termination of the Plan, the balance in each Participant's Plan
Account shall be refunded within 21 days of such termination.

      (c) Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board shall be entitled to change the Offering Periods, limit the frequency
and/or number of changes in the amount withheld during an Offering Period,
establish the exchange ratio applicable to amounts withheld in a currency other
than U.S. dollars, permit payroll withholding in excess of the amount designated
by a participant in order to adjust for delays or mistakes in the Company's
processing of properly completed withholding elections, establish reasonable
waiting and adjustment periods and/or accounting and crediting procedures to
ensure that amounts applied toward the purchase of Common Stock for each
participant properly correspond with amounts withheld from the participant's
Compensation, and establish such other limitations or procedures as the
Administrator determines in its sole discretion advisable which are consistent
with the Plan.

                                     - 8 -

      (d) In the event the Board determines that the ongoing operation of the
Plan may result in unfavorable financial accounting consequences, the Board may,
in its discretion and, to the extent necessary or desirable, modify or amend the
Plan to reduce or eliminate such accounting consequence including. Such
modifications or amendments shall not require stockholder approval or the
consent of any Plan Participants.

      7.3 Use of Funds; No Interest Paid.

      All funds received by the Company by reason of purchase of Common Stock
under this Plan will be included in the general funds of the Company free of any
trust or other restriction and may be used for any corporate purpose. No
interest will be paid to any Participant or credited under the Plan.

      7.4 Term; Approval by Stockholders.

      The Plan shall terminate on the tenth anniversary of the date of its
initial approval by the stockholders of the Company, unless earlier terminated
by action of the Board for any reason including, but not limited to, a change in
the accounting methods that would adversely affect the Company. No option may be
granted during any period of suspension of the Plan or after termination of the
Plan. The Plan will be submitted for the approval of the Company's stockholders
within 12 months before or after the date of the Board's initial adoption of the
Plan. Options may be granted prior to such stockholder approval; provided,
however, that such options shall not be exercisable prior to the time when the
Plan is approved by the stockholders; provided further that if such approval has
not been obtained by the end of the 12-month period following the Board's
initial adoption of the Plan, all options previously granted under the Plan
shall thereupon be canceled and become null and void.

      7.5 Effect Upon Other Plans.

      The adoption of the Plan shall not affect any other compensation or
incentive plans in effect for the Company or any Subsidiary. Nothing in this
Plan shall be construed to limit the right of the Company or any Subsidiary (a)
to establish any other forms of incentives or compensation for employees of the
Company or any Subsidiary or (b) to grant or assume options otherwise than under
this Plan in connection with any proper corporate purpose, including, but not by
way of limitation, the grant or assumption of options in connection with the
acquisition, by purchase, lease, merger, consolidation or otherwise, of the
business, stock or assets of any corporation, firm or association.

      7.6 Conformity to Securities Laws.

      Notwithstanding any other provision of this Plan, this Plan and the
participation in this Plan by any individual who is then subject to Section 16
of the Exchange Act shall be subject to any additional limitations set forth in
any applicable exemptive rule under Section 16 of the Exchange Act (including
any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the
application of such exemptive rule. To the extent permitted by applicable law,
the Plan shall be deemed amended to the extent necessary to conform to such
applicable exemptive rule.

of any disposition of shares of Common Stock, acquired pursuant to the Plan,

            Section 2.1 Initial Elections. A Director may elect, on or before
December 31 of any Plan Year, to defer payment of all or a specified part of all
Fees earned during the Plan Year following such election (and, to the extent set
forth in Section 2.2, in any succeeding Plan Years until the Director ceases to
be a Director); provided, however, that with respect to Plan Year 2005 a
Director may elect, within thirty (30) days after the Effective Date, to defer
all or a specified part of all Fees payable with respect to services rendered
after the date of the Director's initial election. Any person who shall become a
Director during any Plan Year, and who was not a Director of the Company on the
preceding December 31, may elect, no later than thirty (30) days after the
Director's term begins, to defer payment of all or a specified part of such Fees
payable with respect to services rendered during the remainder of such Plan Year
(and, to the extent set forth in Section 2.2, for any succeeding Plan Years
until the Director ceases to be a Director). Any Fees deferred pursuant to this
Paragraph shall be paid to the Director at the time(s) and in the manner
specified in Article IV hereof, as designated by the Director.

            Section 2.2 Subsequent Elections. With respect to Plan Years
following Plan Year 2005, if a Director fails to submit a Deferral Election Form
by December 31 of the Plan Year immediately prior to such Plan Year, the amount
of the deferral election for such Plan Year shall be zero; provided, however,
that, to the extent permitted by Section 409A, a Deferral Election Form may
provide that that the election shall continue from Plan Year to Plan Year unless
the Director terminates it by written request delivered to the Company's
Secretary prior to the commencement of the Plan Year for which the termination
is first effective.

            Section 2.3 Deferral Election Form. The election to participate in
the Plan and manner of payment shall be designated by submitting a deferral
election form in substantially the form attached hereto as Exhibit A (as it may
be revised from time to time, the "Deferral Election Form") to the Company's
Secretary.

            Section 2.4 Limitations on Re-Deferrals. In the event that a
Deferral Election Form permits, under a subsequent election by the Director to
delay a distribution, or to change the form of distribution, such subsequent
election shall satisfy the requirements of Section 409A (including without
limitation Section 409A(a)(4)(C) of the Code), and:

            (a) Such subsequent election may not take effect until at least
twelve (12) months after the date on which the election is made;

            (b) In the case such subsequent election relates to a distribution
or payment not described in Section 4.1(b), (c) or (f), the first payment with
respect to such election may be deferred for a period of not less than five (5)
years from the date such distribution or payment otherwise would have been made;
and

            (c) In the case such subsequent election relates to a distribution
or payment described in Section 4.1(d), such election may not be made less than
twelve (12) months prior to the date of the first scheduled distribution or
payment under Section 4.1(d).

                                  ARTICLE III.
                         DEFERRED COMPENSATION ACCOUNTS

            Section 3.1 Bookkeeping Accounts. The Company shall maintain
separate bookkeeping accounts for the Fees deferred by each Director (the
"Deferred Fees").

            Section 3.2 Deferred Stock Units. As of the date that any Deferred
Fees would otherwise have been payable to a Director, the Company shall credit
such Director's Account with that number of Deferred Stock Units equal to the
ratio of (a) the aggregate value of such Deferred Fees, to (b) the Fair Market
Value per share of Common Stock as of such date.

            Section 3.3 Dividends. As of the date the Company pays any dividend
(whether in cash or in kind) on shares of Common Stock, each Director's Deferred
Compensation Account shall be credited with that number of Deferred Stock Units
equal to the ratio of (a) the aggregate value of the dividend that would have
been payable on the Deferred Stock Units held by the Director immediately prior
to such payment date had the shares of Common Stock represented by such Deferred
Stock Units been outstanding as of such payment date to (b) the Fair Market
Value per share of Common Stock as of such date.

            Section 3.4 Unsecured General Creditor; Fund. Deferred Fees and any
deemed earnings with respect thereto shall be held in the general assets of the
Company and no separate fund or trust shall be created or moneys set aside on
account of the Account. To the extent that any person acquires a right to
receive distributions from the Company under the Plan, such right shall be no
greater than the right of any unsecured general creditor of the Company.
Notwithstanding the foregoing, the Board, in its discretion, may elect to
establish a fund (the "Fund") containing assets equal to the amounts credited to
Directors' Accounts, and may elect in its discretion to designate a trustee to
hold the Fund in trust; provided, however, that such Fund shall remain a general
asset of the Company subject to the rights of creditors of the Company in the
event of the Company's bankruptcy or insolvency as defined in any such trust.

                        PAYMENT OF DEFERRED COMPENSATION

            Section 4.1 Distributions. Subject to Sections 4.1(a)-(f) and 4.2,
amounts contained in a Director's Account shall be distributed as the Director's
election (made pursuant to Section 2.3) shall provide. Notwithstanding the
foregoing, all amounts contained in a Director's account shall be distributed in
accordance with the requirements of Section 409A (including without limitation
Section 409A(a)(2) of the Code), and shall not be distributed earlier than:

            (a) The date of the Director's Separation from Service;

            (b) The date the Director becomes Disabled;

            (c) The date of the Director's death;

            (d) A specified time (or pursuant to a fixed schedule) specified
under the Deferral Election Form at the date of the deferral compensation;

            (e) To the extent provided by the Secretary of the Treasury, a
Change in Control; or

            (f) The occurrence of an unforeseeable emergency with respect to the
Director. The requirement of this Section 4.1(f) shall be met only if, as
determined under Treasury Regulations under Section 409A(a)(2)(B)(ii) of the
Code, the amounts distributed with respect to the unforeseeable emergency do not
exceed the amounts necessary to satisfy such unforeseeable emergency plus
amounts necessary to pay taxes reasonably anticipated as a result of the
distribution, after taking into account the extent to which such unforeseeable
emergency is or may be relieved through reimbursement or compensation by
insurance or otherwise or by liquidation of the Director's assets (to the extent
the liquidation of such assets would not itself cause severe financial
hardship).

            Section 4.2 Specified Employee. If at the time any distributions
would otherwise be made to a Director pursuant to Section 4.1(a) the Director is
a Specified Employee, the requirement of paragraph 4.1(a) shall be met only if
the distributions may not be made before the date which is six months after the
Director's Separation from Service (or, if earlier, the date of the Director's
death).

            Section 4.3 Form of Distribution. All distributions from the Plan
shall be made in the form of whole shares of Common Stock with fractional shares
paid in cash.

            Section 4.4 No Acceleration. The time or schedule of any
distribution of any shares of Common Stock shall not be accelerated, except as
otherwise permitted under Section 409A (including without limitation Section
409A(a)(3) of the Code).

            Section 4.5 Beneficiary Designation. Each Director shall have the
right to designate a beneficiary who is to succeed to his or her right to
receive payments hereunder in the

                                       5
<PAGE>

event of death. Except as may otherwise be provided in any Deferral Election
Form, in the event of the Director's death, the balance of the amounts contained
in the Director's Account shall be paid, in accordance with Section 4.1, to the
Director's or former Director's beneficiary (or if no beneficiary has been
designated, to his estate) in full on the first day of the Plan Year following
the Plan Year in which he or she dies. No designation of beneficiary or change
in beneficiary shall be valid unless it is in writing signed by the Director and
filed with the Company's Secretary.

                                   ARTICLE V.
                            ADMINISTRATION; AMENDMENT

            Section 5.1 Administration. The Plan shall be administered by the
Board. The Board may delegate certain administrative authority to a committee or
subcommittee of the Board or to one or more employees of the Company, but shall
retain the ultimate responsibility for the interpretation of, and amendments to,
the Plan. Members of the Board shall not be liable for any of their actions or
determinations made in good faith with respect to the administration of the
Plan. Except to the extent superseded by the laws of the United States, the laws
of the State of Delaware, without regard to its conflict of laws principles,
shall govern in all matters relating to the Plan. All expenses related to plan
administration shall be paid by the Company. All decisions made by the Board
with respect to issues hereunder shall be final and binding on all parties.

            Section 5.2 Change in Capitalization of the Company. In the event of
any stock dividend, stock split, combination or exchange of shares, merger,
consolidation, spin-off, recapitalization or any other corporate event affecting
the Common Stock or the share price of the Common Stock, the Board may, in its
sole discretion, make such equitable adjustments, if any, with respect to the
Directors' Accounts (including, without limitation, adjusting the number of
Deferred Stock Units credited thereto and/or the kind of securities represented
thereby), as the Board may deem necessary or appropriate to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under this Plan and to reflect such changes.

            Section 5.3 Nonassignability. Except to the extent required by law,
the right of any Director or any beneficiary to any benefit or to any payment
hereunder shall not be subject in any manner to attachment or other legal
process for the debts of such Director or beneficiary, and any such benefit or
payment shall not be subject to alienation, sale, transfer, assignment or
encumbrance.

            Section 5.4 Amendment. The Plan may be amended, suspended or
terminated in whole or in part from time to time by the Board except that,
except as set forth in Section 5.5, no amendment, suspension, or termination
shall apply to the payment to any Director or beneficiary of a deceased Director
of any amounts previously credited to a Director's Account.

            Section 5.5 Section 409A. The Plan and Deferral Election Form shall
be interpreted in accordance with, and shall comply in form and operation with,
Section 409A. Notwithstanding any provision of the Plan to the contrary, the
Board may adopt such amendments to the Plan and the applicable Deferral Election
Form or adopt other policies and

                                       6
<PAGE>

procedures (including amendments, policies and procedures with retroactive
effect), or take any other actions, that the Board determines are necessary or
appropriate to (a) exempt the deferral from Section 409A of the Code and/or
preserve the intended tax treatment of the benefits provided with respect to the
deferral, or (b) comply with the requirements of Section 409A (including without
limitation any related Department of Treasury guidance).

                                    * * * * *

            I hereby certify that the Plan was adopted by the Board of Directors
