Exhibit 10.1



                               UNOCAL CORPORATION
                    2004 DIRECTORS' DEFERRED COMPENSATION AND
                        RESTRICTED STOCK UNIT AWARD PLAN
             (As Amended and Restated Effective as of May 23, 2005)

1.   General Description.

     The  Plan  provides  for  annual  grants  of  restricted   stock  units  to
non-employee directors.  Non-employee directors may also elect to defer all or a
portion of their annual cash  compensation  into stock units  subject to certain
conditions.

     The purpose of the Plan is to attract,  motivate and retain experienced and
knowledgeable  directors by offering  additional  stock based  compensation  and
incentives to defer and potentially  enhance their compensation and to encourage
stock ownership in the Company.

2.   Definitions.

The following definitions shall be applicable throughout the Plan:

         "Board" means the Board of Directors of the Company.

         "Change in Control" means the occurrence of any of the following:

                  (a) The acquisition by any individual, entity or group (within
                  the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange
                  Act (a "Person") of beneficial ownership (within the meaning
                  of Rule 13d-3 promulgated under the Exchange Act) of 20% or
                  more of either (i) the then outstanding shares of common stock
                  of the Company (the "Outstanding Company Common Stock") or
                  (ii) the combined voting power of the then outstanding voting
                  securities of the Company entitled to vote generally in the
                  election of directors (the "Outstanding Company Voting
                  Securities"); provided, however, that for purposes of this
                  subsection (a), the following acquisitions shall not
                  constitute a Change in Control: (i) any acquisition directly
                  from the Company, (ii) any acquisition by the Company, (iii)
                  any acquisition by an employee benefit plan (or related trust)

                  controlled by the Company or (iv) any acquisition by any
                  entity pursuant to a transaction which satisfied conditions
                  (i), (ii) and (iii) of clause (c) below.

                  (b) Individuals who, as of the Effective Date, constitute the
                  Board (the "Incumbent Board") cease for any reason to
                  constitute at least a majority of the Board; provided,
                  however, that any individual becoming a director subsequent to
                  the Effective Date whose election, or nomination for election
                  by the Company's stockholders, was approved by a vote of at
                  least a majority of the directors then comprising the
                  Incumbent Board shall be considered as though such individual
                  were a member of the Incumbent Board, except that, any such
                  individual whose

                                      -1-


                  initial assumption of office occurs as a result of an actual
                  or threatened election contest with respect to the election or
                  removal of directors or other actual or threatened
                  solicitation of proxies or consents by or on behalf of a
                  Person other than the Board shall not be considered a member
                  of the Incumbent Board; or

                  (c) Consummation of a reorganization, merger or consolidation
                  or sale or other disposition of all or substantially all of
                  the assets of the Company or the acquisition of assets of
                  another entity (a "Business Combination"), in each case,
                  unless, following such Business Combination, (i) all or
                  substantially all of the individuals and entities who were the
                  beneficial owners, respectively, of the Outstanding Company

                  immediately prior to such Business Combination will

                  respectively, the then outstanding shares of common stock and
                  the combined voting power of the outstanding voting securities
                  entitled to vote generally in the election of directors, as
                  the case may be, of the entity resulting from such Business
                  Combination, including, without limitation, an entity which as
                  a result of such transaction owns the Company or all or
                  substantially all of the Company's assets either directly or
                  through one or more subsidiaries (the "Resulting Entity") in
                  substantially the same proportions as their ownership,
                  immediately prior to such Business Combination of the
                  Outstanding Company Common Stock and Outstanding Company
                  Voting Securities, as the case may be, (ii) no Person
                  (excluding any Resulting Entity from such Business Combination
                  or any employee benefit plan (or related trust) of the Company
                  or such Resulting Entity from such Business Combination) will
                  beneficially own, directly or indirectly, 20% or more of,
                  respectively, the then outstanding shares of common stock of
                  the entity resulting from such Business Combination or the
                  combined voting power of the then outstanding voting
                  securities of such entity except to the extent that such
                  ownership level existed (with respect to the Company or
                  Resulting Entity) prior to the Business Combination and (iii)
                  at least a majority of the members of the board of directors
                  of the Resulting Entity from such Business Combination were
                  members of the Incumbent Board at the time of the execution of

                  (d) Approval by the stockholders of the Company of a complete

         benefits of the Stock Units with respect to the underlying shares in

3.   Effective Date; Duration.

     The effective date of the Plan is the date on which the stockholders of
the Company approve the Plan. No awards may be granted under the Plan after June
1, 2009. The Plan shall continue in effect until all matters relating to Stock
Units and the accrual and distribution in respect of compensation deferred on or
prior to that date and the administration of the Plan have been completed and
all payments of such compensation have been made.

4.   Administration.

     The Plan shall be administered by the Committee. The acts of a majority
of the members present at any meeting at which a quorum is present and the acts
unanimously approved in writing or by electronic transmission by the Committee
shall be deemed the acts of the Committee.

                                      -4-


     The Committee shall have the authority, subject to the provisions of
the Plan, to establish, adopt and revise such rules, regulations and forms and
agreements and to make all such determinations relating to the Plan as it may
deem necessary or advisable in the administration of the Plan. The Committee

duties and functions to officers and employees of the Company. The Committee's
interpretation of the Plan or any awards granted pursuant thereto and all
decisions and determinations by the Committee with respect to the Plan shall be
final, binding, and conclusive on all parties.

5.   Restricted Stock Units.

     (a) Initial Awards. Any person who first becomes an Eligible Director
on or after January 1, 2004 shall be granted without further action by the
Committee a number of Restricted Stock Units with a total value of $82,500. As
to any person who first becomes an Eligible Director on or before the 2004
annual meeting of stockholders, the date of grant of such Initial Award shall
be the first day of the month immediately following such annual meeting,
and as to any person who subsequently becomes an Eligible Director, the date of
grant of such Initial Award shall be the date the person takes office. The
number of Restricted Stock Units included in each such award shall be determined
by dividing $82,500 by the Fair Market Value of the Stock on the date of grant.
The Company shall credit to the Eligible Director's Stock Unit Account the
number of whole and fractional RSUs so determined.  Notwithstanding the
foregoing, the Board may, from time to time, in its sole  discretion, adjust
(upward or downward) the nominal dollar value of such initial awards;  provided
however that the Board may not increase the nominal dollar value of an initial
award under this Section 5(a) to more than $165,000 in the aggregate during the
term of the Plan.

     (b) Annual Awards. On the first day of the month immediately  following the
annual  meeting of  stockholders  in 2004,  and on June 1 in each  calendar year
thereafter,  each  Eligible  Director  then in office  shall be granted  without
further action by the Committee a number of Restricted  Stock Units with a total
value of $70,000.  The number of  Restricted  Stock Units  included in each such
award shall be  determined  by dividing  $70,000 by the Fair Market Value of the
Stock on the date of grant. The Company shall credit to the Eligible  Director's
Stock  Unit  Account  the  number of whole and  fractional  RSUs so  determined.
Notwithstanding  the  foregoing,  the Board may,  from time to time, in its sole
discretion,  adjust (upward or downward) the nominal dollar value of such annual
awards;  provided,  however that the Board may not increase the nominal value of
an annual award under this Section 5(b) to more than  $140,000 in the  aggregate
during the term of the Plan.

     (c) Maximum Number of Shares; Individual Award Limits. Annual grants that
would otherwise exceed the maximum number of shares allotted for issuance under
the Plan contained in Section 9(a) shall be prorated within such limitation
pursuant to Section 9(b). An Eligible Director shall not receive more than one
Restricted Stock Unit award under this Section 5 in any calendar year.
Commencing in 2005, if an Eligible Director is first eligible for a Restricted
Stock Unit award under the Plan on June 1 of a year, the  number of shares
subject to the Restricted Stock Unit award will be determined under clause (a)
above.

                                      -5-


     (d) Vesting Period.  For each initial  Restricted  Stock Unit award granted
under  Section  5(a),  33 1/3% of the RSUs  subject to the award  shall vest and
become  nonforfeitable  on each of the first three (3) anniversaries of the date
of grant.  For each annual  Restricted  Stock Unit award  granted  under Section
5(b),  33  1/3%  of the  RSUs  subject  to  the  award  shall  vest  and  become
nonforfeitable  on each of the first three (3) annual  meetings of  stockholders
following the date of grant. Notwithstanding the foregoing, the Board may modify
the vesting  schedule for any RSU award,  provided  that the Board  modifies the
schedule in advance of the grant of the award and the modified  vesting schedule
results  in  vesting in any year of no less than 20% and no more than 50% of the
award.

     (e) Acceleration of Vesting.  Notwithstanding Section 5(d), each Restricted
Stock Unit award shall become  immediately vested and  non-forfeitable  upon the
occurrence of any of the following events:

          (1)  a Participant's  service as a director is terminated due to death
               or Disability,

          (2)  a Change in Control,

          (3)  a Participant  retires from service  either (A) at the end of the
               Participant's  then current term and after  completing  five full
               years of service if the  Participant  is  ineligible to stand for
               reelection under the Company's director  retirement policy or (B)
               under the Company's director retirement policy on the date of the
               Annual Meeting of Stockholders  immediately  following his or her
               72nd birthday and after completing five full years of service, or

          (4)  a Participant accepts a public interest position (e.g., community
               service,  philanthropic endeavors, a position with a 501(c)(3) or
               (c)(4)  organization,   or  government  service),  provided  such
               acceleration does not adversely affect the Participant's  ability
               to serve in such position.

     (f) Distribution  Elections.  Subject to Section 8,  Participants may elect
the time of payment of the RSUs awarded under this Section 5. For a distribution
election to be  effective,  any such election must be received by the Company no
later than the applicable deadline for each RSU award, which (1) with respect to
RSUs granted in 2004,  shall be no later than 30 days after the  Effective  Date
and (2) with respect to RSUs granted in subsequent  calendar years,  shall be no
later  than  the  immediately  preceding  December  31 for each  calendar  year.
Notwithstanding the preceding  sentence,  a person who first becomes an Eligible
Director during a calendar year may make a distribution election with respect to
the  initial  RSU award  granted  pursuant to Section  5(a),  provided  that the
election is received by the Company within the 30-day period  following the date
that the person first becomes an Eligible  Director.  An Eligible Director shall
be permitted to make a different  distribution election with respect to each RSU
award. For each Eligible Director who makes one or more distribution  elections,
his or her Stock  Unit  Account  shall be  divided  into two or more  Stock Unit
Subaccounts as necessary or advisable to separately account for RSUs awards that
vest or are payable at different times.

6.   Deferral Units.

     (a) Deferral of Regular Cash Compensation Into Deferral Units.

                                      -6-


     Each Eligible Director may also elect annually to defer all or part of
his or her cash compensation, in increments of no less than 10%, payable for
services rendered as a director, into Deferral Units. An Eligible Director's
election to defer cash compensation shall be irrevocable, except as expressly
provided in the Plan, and shall be effective for compensation earned for
services as a director of the Company for the calendar year with respect to
which the deferral election is made. The amount of compensation earned by an
Eligible Director under the Plan in any month shall be increased by 20% (as so
increased, the "Adjusted Deferral Amount") for purposes of determining the
number of Deferral Units to be credited to such Eligible Director. An Eligible
Director's deferral election shall be made pursuant to the election procedures
in Section 6(c).

     At the end of each quarter, the number of Deferral Units to be credited
to an Eligible Director's Stock Unit Account with respect to deferrals under
this Section 6 shall be the Eligible Director's Adjusted Deferral Amount for
that quarter divided by the average of the Fair Market Values of the Stock over
the quarter.

     (b) Vesting of Deferral  Units.  Deferral  Units shall be fully  vested and
non-forfeitable at all times.

     (c) Deferral Elections.

          (1) For a deferral election to be effective, any such election must be
     received  by the  Company no later  than the  applicable  deadline  for the
     period to which the deferral  relates (but, in any event, no later than the
     immediately preceding December 31 for each calendar year).  Notwithstanding
     the preceding  sentence,  a person who first  becomes an Eligible  Director
     during a calendar  year may make a deferral  election  with  respect to the
     compensation  payable through the end of that calendar year,  provided that
     (a) the  election  is  received  by the  Company  within the 30-day  period
     following the date that the person first becomes an Eligible Director,  and
     (b) the  election  applies  only to  compensation  earned for services as a
     Board member  after the date the  election is received by the  Company.  As
     provided in Section 14, with respect to compensation earned or to be earned
     in calendar year 2004, any deferral  election made by an Eligible  Director
     under the  Former  Plan with  respect  to such 2004  compensation  shall be
     effective for the deferral of such 2004 compensation under this Plan.

          (2) An  Eligible  Director  shall  be  permitted  to make a  different
     election with respect to each annual  deferral period and as to the time in
     which his or her benefits shall be distributed.  For each Eligible Director
     who makes one or more distribution elections, his or her Stock Unit Account
     shall be divided  into two or more Stock Unit  Subaccounts  as necessary or
     advisable  to  separately  account  for  deferrals  which  are  payable  at
     different times.

7.   Dividend Equivalent Units.

     (a) As of the end of each  quarter  in which a  dividend  is paid on Stock,
additional  Stock Units (or portions  thereof)  will be credited to the Eligible
Director's Stock Unit  Subaccounts.  The number of Stock Units so credited shall
equal the cash dividend (or declared



value of any other dividend) per share multiplied by the number of Stock Units
in the Eligible Director's Stock Unit Subaccounts as of the end of the
immediately preceding quarter divided by the average of the Fair Market Values
of a share of Stock over the quarter then ending. Dividend equivalent Stock
Units credited in respect of RSU awards shall be vested to the same extent as
the RSU awards to which they relate.

     (b) If a Stock Unit distribution  event occurs after a dividend record date
and after the dividend payment date but before the dividend equivalent crediting
date set forth in  Section  7(a),  then the  crediting  of  dividend  equivalent
rights,  with respect to such  dividend  and such  distributed  shares,  will be
settled in cash,  in lieu of  additional  Stock  Units,  as soon as  practicable
following  such  Stock  Unit  distribution  based on the total  number of shares
distributed.  Notwithstanding the foregoing,  if a Stock Unit distribution event
occurs  after a dividend  record date but before a dividend  payment  date,  the
crediting  of  dividend  equivalent  rights,  with  respect to such  distributed
shares,  will be settled in cash,  in lieu of  additional  Stock  Units,  on the
dividend payment date based on the total number of shares distributed.

     (c) Stock Units credited in respect of dividend  equivalents  shall be paid
in Stock  (except as provided in Section 7(b) and Section 9(b)) at the same time
and the same manner as the vested Stock Units to which they relate.

8.   Restrictions, Distributions and Changes to Distributions; Payment of Units.

     (a) Time and Manner of Distribution. Unless a Participant elects otherwise,
distribution  with  respect to vested  Stock Units will be made in a lump sum as
soon as  administratively  practicable  following  the  earlier  to  occur  of a
termination  of the  Participant's  service  as a director  of the  Company or a
Change in Control.  However,  a Participant  may elect that the  distribution be
made (1) on a termination of service as a director,  (2) on an alternative date,
(3) on the earlier of termination  of service or an  alternative  date or (2) on
the later of termination of service or an alternative  date. The Participant may
also elect whether or not a Change in Control will accelerate  distribution.  In
the case of a Restricted Stock Unit award, the earliest alternative distribution
date that a  Participant  may elect is the later of the date of full  vesting of
the  award or three  years  after the date of the  grant of the  award,  and the
latest  alternative  distribution  date that a Participant may elect is 15 years
after the date of the grant of the award.  In the case of  Deferral  Units,  the
earliest  alternative  distribution  date that a Participant  may elect is three
years  after the  calendar  year for which the  Participant's  compensation  was
deferred into such Deferral Units, and the latest date alternative  distribution
date that a Participant  may elect is 15 years after the calendar year for which
the  compensation was deferred into such Deferral Units. Any election under this
Section 8(a) must be made by the Participant in writing on forms provided by the
Company at the time of making the  distribution  election  under Section 5(f) or
the deferral election under Section 6(c), whichever is applicable.

     Notwithstanding any contrary elections or other terms of the Plan, a
Participant shall receive an immediate crediting and distribution of vested
Stock Units (which includes any Stock Units that become vested pursuant to
Section 5(e)(4)) under the Plan if a Participant accepts a public interest
position (e.g., community service, philanthropic endeavors, a position with a
501(c)(3) or (c)(4) organization, or government service), provided such
acceleration does not adversely affect the Participant's ability to serve in
such position.

                                      -8-


     (b)  Change in Time of  Distribution.  An  Eligible  Director  may elect to
further defer the  commencement  of any  distribution to be made with respect to
Stock Units benefits  payable under the Plan by filing a new written election in
a form and manner approved by the Committee; provided, however, that (A) no such
new election  shall be effective  until 12 months after such  election is filed,
(B) no such new  election  shall be  effective  with  respect to any Stock Units
after the  distribution  of benefits with respect to the applicable  Stock Units
subaccount  shall have  commenced,  and (C) no more than two new elections  with
respect to any annual deferral period or single RSU award shall be recognized as
to any  Participant.  In  addition,  to the extent  necessary  to  preserve  the
benefits of the  exemptive  rules under Section 16 of the Exchange Act, any such
new election shall be subject to prior approval of the Board or the Committee.

     (c)  Early  Distributions.  Participant  shall  be  permitted  to  elect to
withdraw  (subject to  Committee  approval  to the extent  required to avoid any
matchable  event under  Section  16(b) of the Exchange Act) not less than 50% of
the vested  portion of his or her Stock Unit Account,  reduced by the withdrawal
penalty  described  below,  prior  to the  applicable  payment  date(s)  ("Early
Distributions"), subject to the following restrictions:

          (1) The  election  to  take an  Early  Distribution  shall  be made in
     writing on a form provided by and filed with the Committee;

          (2) The amount of the Early Distribution shall equal 90% of the amount
     the Eligible Director has elected to withdraw;

          (3) The remaining 10% of the amount the Eligible  Director has elected
     to withdraw shall be permanently surrendered,  and the Eligible Director or
     his  or  her  Beneficiary  shall  have  no  rights  with  respect  to  such
     surrendered amounts; and

          (4) Unless the Committee  otherwise  provides,  no more than two early
     distribution elections shall be recognized as to any Participant.

The Eligible Director's remaining Stock Units in the Stock Unit Account shall
continue to be credited with Dividend Equivalents in accordance with Section 7.

     (d) Distributions for Unforeseeable  Emergencies. A Participant may request
a  distribution  of the  vested  portion  of  Participant's  Stock  Units for an
Unforeseeable   Emergency   (without  penalty  or  surrender  of  rights).   Any
distribution for an Unforeseeable  Emergency shall be subject to approval by the
Committee in its sole discretion and may be made only to the extent necessary to
satisfy the hardship.

     The Committee may treat a distribution as necessary for an Unforeseeable
Emergency if it relies on the Eligible Director's written representation,
without actual knowledge to the contrary, that the hardship cannot reasonably be
relieved through timely reimbursement or compensation by insurance or otherwise,
or by liquidation of the Eligible Director's assets, to the extent the
liquidation of such assets would not itself cause severe financial hardship.

     (e) Payment of Units. Upon a distribution event, the Company shall, subject
to  Section  9(b)  hereunder,  deliver a number of shares of Stock  equal to the
number of vested  Stock  Units (as  adjusted  pursuant  to  Section  8(c)(3)  if
applicable) to which the Participant is then

                                      -9-


entitled (whether upon his or her previously elected distribution date,
determination of Unforeseeable Emergency or voluntary withdrawal under
Section 8(c)(3)) under the terms of the Plan.

     (f)  Forfeiture  of  Unvested  Units.  To  the  extent  any  portion  or  a
Participant's  RSUs  have not  become  vested  upon  the date the  Participant's
services as a director  terminate,  such RSUs shall be  forfeited  and the award
shall  automatically  be  terminated  without  payment of  consideration  by the
Company.

9.   Shares Subject To The Plan; Share Limits.

     (a) Shares Available for Issuance.  Subject to adjustment under Section 11,
the  aggregate  number of shares of Stock that may be issued or delivered  under
the Plan shall not exceed 500,000  shares.  Stock delivered by the Company under
the Plan  shall be shares of  authorized  and  unissued  shares of Stock  and/or
previously  issued  Stock  held as  treasury  shares and shall be fully paid and
non-assessable  when issued.  Shares issuable on payment of Stock Units shall be
reserved for issue, and to the extent that awards  terminate  without payment in
shares,  the shares will be available  for  subsequent  awards or  accretions of
dividend equivalents.

     (b) Share Limits; Cut Backs. If any award or crediting of Stock Units would
cause the sum of the shares of Stock previously issued and shares issuable under
outstanding  awards  under  the Plan to  exceed  the  maximum  number  of shares
authorized  under  the Plan,  the  Company  shall  prorate  among  the  Eligible
Directors  the award of  Restricted  Stock  Units  and  allocate  the  number of
remaining  shares  available for issuance first to the award of Restricted Stock
Units and second toward the crediting of Deferral  Units.  If and for so long as
no available  share  authorization  remains,  no additional  Stock Units will be
credited, cash shall be paid in lieu of dividend equivalents under Section 7 for
such duration and any contrary or inconsistent elections shall be deemed revised
or rescinded accordingly.

     (c) Fractional  Shares;  Minimum Issue.  Fractional  share interests may be
accumulated but shall not be issued. Cash will be paid or transferred in lieu of
any fractional share interests that remain upon a final  distribution  under the
Plan.

10.  General.

     (a)  Government  and Other  Regulations.  The  obligation of the Company to
credit Stock Units,  issue or deliver Stock or otherwise make payments under the
Plan are subject to compliance with all applicable laws,  rules, and regulations
(including,  without limitation, federal and state securities laws), and to such
approvals by any listing,  agency, or regulatory or governmental  authorities as
may, in the opinion of counsel for the  Company,  be  necessary  or advisable in
connection therewith. The Company shall be under no obligation to register under
the Securities Act any of the securities issued or delivered under the Plan. Any
securities  issued  or  delivered  under  the  Plan  shall  be  subject  to such
restrictions,  and the person  acquiring such securities  shall, if requested by
the Company,  provide such assurances and representations to the Company, as the
Company may deem necessary or advisable to assure compliance with all applicable
legal requirements.

                                      -10-


     (b) Tax  Withholding.  The Company  shall have the right to deduct from all
cash  payments  any  federal,  state or local  taxes as  required  by laws to be
withheld with respect to such cash payments and, with respect to the delivery of
Stock,  the Company has the right to require the person  receiving such Stock to
pay to the Company the amount of any such taxes which the Company is required to
withhold.  The Company may, in lieu of requiring cash payment of any such taxes,
elect to withhold  from Stock  payments a number of whole  shares of Stock whose
value is at least equal to the amount of such taxes.  Valuation for this purpose
shall be the Fair Market Value on the date of distribution.

     (c)  Beneficiaries.

          (1)  Beneficiary  Designation.  Upon and subject to the terms of forms
     provided by the Company each Eligible Director may designate in writing the
     Beneficiary  or  Beneficiaries  (as defined in Section  10(c)(2)) whom such
     Eligible  Director  desires to receive any amounts  payable  under the Plan
     after his or her death. Beneficiary designation forms shall be effective on
     the date that the form is received by the Corporate Secretary.  An Eligible
     Director may from time to time change his or her designated  Beneficiary or
     Beneficiaries  without the consent of such  Beneficiary or Beneficiaries by
     filing a new designation in writing with the Corporate Secretary.  However,
     if a married Eligible  Director wishes to designate a person other than his
     or her spouse as  Beneficiary,  such  designation  shall be consented to in
     writing by the  spouse.  The  Eligible  Director  may  change any  election
     designating a  Beneficiary  or  Beneficiaries  without any  requirement  of
     further   spousal   consent   if  the   spouse's   consent   so   provides.
     Notwithstanding the foregoing, spousal consent shall not be necessary if it
     is established  that the required  consent  cannot be obtained  because the
     spouse  cannot be located or because of other  circumstances  prescribed by
     the  Committee.  The Company  and the  Committee  may rely on the  Eligible
     Director's  designation  of a Beneficiary  or  Beneficiaries  last filed in
     accordance with the terms of the Plan.

          (2) Definition of Beneficiary. An Eligible Director's "Beneficiary" or
     "Beneficiaries" shall be the person, persons, trust or trusts so designated
     by the Eligible Director or, in the absence of such  designation,  entitled
     by will or the laws of descent and  distribution  to receive  the  Eligible
     Director's  benefits under the Plan in the event of the Eligible Director's
     death, and shall mean the Eligible  Director's executor or administrator if
     no other Beneficiary is identified and able to act under the circumstances.

     (d)   Non-transferability.   Except  as  provided  in  Section   10(c),   a
Participant's  rights and  interests  under the Plan in respect of Stock  Units,
including amounts payable or Stock deliverable under or in respect thereof,  may
not be assigned, pledged, or transferred.

     (e) Expenses.  The expenses of administering the Plan shall be borne by the
Company.

     (f) Titles and  headings.  The titles and  headings of the  sections in the
Plan are for  convenience  of reference  only, and in the event of any conflict,
the text of the Plan, rather than such titles or headings, shall control.

                                      -11-


     (g) Governing  Law. The validity of the Plan or any of its  provisions  and
any agreements entered into under the Plan shall be construed,  administered and
governed  in all  respects  under  the  laws of the  State of  Delaware.  If any
provisions of the Plan shall be held by a court of competent  jurisdiction to be
invalid or unenforceable,  the remaining  provisions hereof shall continue to be
fully effective.

     (h) Limitation on Participants' Rights; Unfunded Plan. Participation in the
Plan shall not give any person the right to continue to serve as a member of the
Board or any rights or interests  other than as expressly  provided  herein.  No
Participant  shall have any right to any payment or benefit  hereunder except to
the extent provided herein. The Plan shall create only a contractual  obligation
on the part of the  Company as to such  amounts  and shall not be  construed  as
creating a trust or fiduciary  relationship  between the Company, the Board, the
Committee,  and  any  Participant  or  other  person.   Participants  and  their
Beneficiaries  shall have no legal or equitable  rights,  claims, or interest in
any specific  property or assets of the Company.  No assets of the Company shall
be held  under any  trust,  or held in any way as  collateral  security  for the
fulfilling of the obligations of the Company under this Plan. Any and all of the
Company's  assets  shall be, and  remain,  the general  unpledged,  unrestricted
assets of the Company.  The Company's  obligation under the Plan shall be merely
that of an unfunded and unsecured  promise of the Company to pay benefits in the
future, and the rights of the Participants and Beneficiaries shall be no greater
than  those  of  unsecured  general  creditors.  Notwithstanding  the  foregoing
provisions of this Section 10(h), nothing herein shall prohibit the Company from
establishing   and  funding  a  "rabbi  trust"  with  respect  to  one  or  more
Participant's deferred compensation distributions pursuant to the Plan.

     (i) Rights with Respect to Stock Units. A Participant's  Stock Unit Account
shall be a  memorandum  account  on the books of the  Company.  The Stock  Units
credited  to such  account  shall be used  solely as a device to  determine  the
number of  shares  of Stock to be  eventually  distributed  to the  Participant,
subject to applicable  vesting  requirements,  in accordance  with the Plan. The
Stock Units shall not be treated as property or as a trust fund of any kind.  No
Participant  shall be  entitled to any voting or other  stockholder  rights with
respect to Stock Units credited under the Plan.

     (j) Restricted  Stock Unit  Agreements.  Each  Restricted  Stock Unit award
granted to an Eligible  Director  under the Plan shall be evidenced by a writing
approved by the Committee and will contain the terms and  conditions  consistent
with the Plan as approved by the Committee relating to the RSUs.

     (k) Plan Construction.  By its approval of the Plan, the Board intends that
the transactions contemplated by the Plan satisfy and be interpreted in a manner
that satisfies the applicable  requirements of Rule 16b-3  promulgated under the
Exchange Act so that,  among other  transactions,  the elective  deferrals,  the
crediting  of Stock Units and payment in Stock,  and other  elections in respect
thereof will be entitled to the benefits of Rule 16b-3 or other  exemptive rules
under Section 16 of the Exchange Act.

                                      -12-


11.  Changes in Capital Structure.

     Upon or in contemplation of any reclassification, recapitalization,
stock split (including a stock split in the form of a stock dividend) or reverse
stock split; any merger, combination, consolidation or other reorganization; any
split-up; spin-off, or similar extraordinary dividend distribution in respect of
the Stock (whether in the form of securities or property); any exchange of Stock
or other securities of the Company, or any similar, unusual or extraordinary
corporate transaction in respect of the Stock; or a sale of substantially all
the assets of the Company as an entirety; then the Board shall, in such manner,
to such extent (if any) and at such time as it deems appropriate and equitable
in the circumstances proportionately adjust any or all of (a) the number and
type of shares of Stock (or other securities or property) that thereafter may be
made the subject of Stock Units and Stock Unit Accounts (including the specific
maxima and numbers of shares set forth elsewhere in the Plan), (b) the number,
amount and type of shares of Stock (or other securities or property) payable in
respect of Stock Units, and (c) and the number and type of Stock Units (both
credited and vested), and applicable vesting schedule thereof, under the Plan.

     Any rights in respect of cash or any equivalent into which the Stock or
rights to receive stock may be or have been converted as a result of an event
contemplated by this Section 11 shall include a right to quarterly interest
credits based upon the rate (quoted as an annual rate) that is 120% of the
federal rate for compounding for the applicable period of time to payment,
determined and published by the Secretary of the United States Department of
Treasury under Section 1274(d) of the Code, for the month in which interest is
credited.

12.  Amendments and Termination.

     Subject to Section 13, the Board shall have the right to amend the Plan
(including outstanding awards) in whole or in part from time to time or may at
any time suspend or terminate the Plan; provided, however, that no amendment or
termination shall cancel or otherwise adversely affect in any way, without his
or her written consent, any Participant's rights with respect to Stock Units
credited to his or her Stock Unit Account. Notwithstanding the foregoing,
Participant consent shall not be required to the extent that the Board
determines that applicable law requires amendment or termination of the Plan
(and/or outstanding awards) to preserve the intended tax benefits to the
Participants and the Company hereunder. Any amendments authorized hereby shall
be stated in an instrument in writing, and all Participants (subject to any
applicable consent requirement above) shall be bound thereby upon receipt of
notice thereof. Changes contemplated by Section 11 shall not be deemed to
constitute changes or amendments for purposes of this Section 12.

13.  Stockholder Approval.

     The Plan shall be subject to approval of the Plan by the stockholders
of the Company at the 2004 annual meeting. To the extent required under
applicable law, listing agency rule, deemed necessary or advisable by the Board
any subsequent amendment to the Plan shall be subject to stockholder approval.
Changes contemplated by Section 11 shall not be deemed to constitute changes or
amendments for purposes of this Section 13. Without limiting the

                                      -13-


amendment authority set forth in Section 12, changes specifically contemplated
by Section 5 are deemed approved by the stockholders upon their approval of the
Plan.

14.  Transfer of Accounts from Former Plan.

     The Stock Units (and dividend equivalents credited with respect
thereto) credited to the Stock Unit Account of each Eligible Director who is a
Participant in the Former Plan as of the Effective Date will be transferred to a
Stock Unit Account under this Plan for such Participant as of such date and
thereafter shall be governed by the terms of this Plan. Any deferral election
with respect to compensation earned and to be earned in calendar year 2004 filed
under the Former Plan shall be effective for the deferral of such compensation
under this Plan, and any distribution election and beneficiary designation made
by any Participant under the Former Plan with respect to such transferred Stock
Units (and dividend equivalents credited with respect thereto) shall remain in
effect and apply to such Participant's Accounts and participation under this
Plan unless and until the Participant makes a different election in accordance
with the terms of this Plan. All Stock Units so transferred shall be fully
vested and nonforfeitable.

                                      -14-
