                     SPLIT-DOLLAR LIFE INSURANCE AGREEMENT
                     -------------------------------------

     THIS AGREEMENT, effective as of this 2nd day of May, 1998, is by and
between IMCO RECYCLING INC., a Delaware corporation having its principal
executive offices located in Irving, Texas (the "Company") and Steve B. Ingram,
as Trustee of the INGRAM FAMILY INSURANCE TRUST NO. 1 (the "Trust").

                             W I T N E S S E T H:
                             - - - - - - - - - -

     WHEREAS, this Agreement is entered into in accordance with an award made to
DON V. INGRAM (the "Employee"), who has rendered efforts on behalf of the
Company; and

     WHEREAS, this Agreement is a life insurance employee benefit plan as
described in Revenue Ruling 64-328; and

     WHEREAS, the Company highly values the efforts, abilities, and
accomplishments of the Employee and wishes to retain his services, and as an
inducement thereto, the Company is willing to assist the Trust in the payment of
premiums on life insurance; and

     WHEREAS, in exchange for such premium assistance, the Trust is willing to
return to the Company its Premium Advance as provided herein;

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged by the parties hereto, it is
mutually agreed as follows:

     1.   The Insurance.  In furtherance of the purposes of this Agreement, the
          -------------
Trust shall purchase the policy(ies) described in Exhibit A (the "Insurance")
from one or

                                     - 1 -
<PAGE>

more insurance companies (the "Insurer(s)") specified in Exhibit A (the
"Insurance").  Exhibit A may be amended by the parties to this Agreement, at any
time and from time to time, by a written instrument complying with Section 13 of
this Agreement.  Upon the Employee's death $3,000,000.00 (hereafter referred to
as the "Trust's Death Benefit") shall be payable as the Trust shall have
designated under the Insurance, subject to Section 3 of this Agreement.

     2.   Ownership.  The Trust shall be the sole owner of the Insurance and
          ---------
shall hold the Insurance.  The Trust shall have all the rights of "owner" under
the terms of the Insurance including, but not limited to, the right to designate
beneficiaries, select settlement and dividend options, borrow on the security of
the Insurance, and to surrender the Insurance.  All such rights may be exercised
by the Trust without the Company's consent.

     3.   Repayment of Premium Advance to Company.  The Company's "Premium
          ---------------------------------------
Advance" is an amount equal to the lesser of (i) the cumulative total of the
Company's share of premiums paid on the Insurance (as provided in Section
4(a)(2)), or (ii) the cash surrender value of the Insurance as of the applicable
date.  Subject to Section 6 below, in the event of the death of the Employee,
the "Premium Advance" shall be equal to the greater of (i) the cumulative total
of the Company's share of premiums paid on the Insurance, or (ii) the total
death benefits payable under the Insurance less the Trust's Death Benefit.
Subject to Section 6 below, in exchange for the Company's payment of its premium
contribution under Section 4, the Trust agrees to pay to the Company the amount
of its Premium Advance on the earlier of:

          (1)  Termination of this Agreement as provided in Section 6; or

          (2)  The Employee's death.

                                     - 2 -
<PAGE>

Nothing herein shall give the Company any interest in the Insurance. The Company
will not take any action in dealing with the Insurer(s) that would impair any
right or interest of the Trust in the Insurance.

     4.   Payment of Premiums.
          -------------------

          (a)  Each annual premium on the Insurance shall be paid as follows:

               (1)  At the election of the Company, the Trust shall pay a
          portion of each premium equal to (i) the current term rate of the
          Employee's age, multiplied by (ii) the excess of the current death
          benefit over the Company's current Premium Advance. If the Company
          does not require the Trust to pay a portion of the premium pursuant to
          the preceding sentence, the Company shall pay such amount on behalf of
          the Trust and such amount shall be treated as compensation to the
          Employee. Here, the "current term rate" shall mean the lesser of the
          Insurer's annual term insurance rate or the rates specified in Revenue
          Rulings 64-328 and 66-110.

               (2)  The Company shall pay all premium amounts not paid by the
          Trust.

          (b)  The Trust's premium share (other than that paid with policy
     loans) and the Company's premium share shall be remitted to the Insurer
     before expiration of the grace period for payment of premiums.

          (c)  Dividend on the Insurance shall be applied as elected by the
     Trust.

     5.   Supplements and Riders. Should the Trust deem it desirable,
          ----------------------
application may be made for a supplemental agreement or rider to be attached to
the Insurance.

                                     - 3 -
<PAGE>

Ownership of any such agreement or rider shall be in the Trust and any
additional premiums shall be paid by the Trust.

     6.   Termination of Agreement. This Agreement shall terminate on the
          ------------------------
earliest to occur of the following events:

          (a)  Surrender of the Insurance by the Trust, which has the sole and
     exclusive right of surrender, subject to Section 3 above;

          (b)  Delivery by the Trust of written notice of termination to the
     Company or delivery of written notice by the Company to the Trust;

          (c)  Failure of the Trust to make a premium contribution required in
     Section 4;

          (d)  Written agreement of the Trust and the Company to terminate the
     Agreement; or

          (e)  The tenth (10th) anniversary of the effective date of this
     Agreement.

     Upon termination of the Agreement, the Trust shall pay to the Company the
Premium Advance. Upon termination of the Agreement, the Trust and the Company
may enter into further agreement to continue the terms of this Agreement.

     7.   Policy Loans. It is agreed that no policy loans may be taken by the
          ------------
Trust which would have the effect of reducing the cash surrender value below the
amount of the Premium Advance. Interest on any such policy loans shall be paid
by the Trust, as owner of the policy, as such interest become due.

     8.   Payment of Proceeds. At the death of the Employee, the Company and the
          -------------------
Trust shall execute such forms and furnish such other documents or information
as are required to receive payments under the Insurance as contemplated herein.

     All death benefits under this Agreement shall be paid in accordance with
the terms and conditions of the Insurance and pursuant to the claims and review

                                     - 4-

procedures of the Insurer. The Company's liability to provide benefits under
this Agreement shall be limited solely to the payment of its share of premiums,
as provided in Section 4. The Company assumes no responsibility for payment of
death benefits under the Insurance.

     9.   Payment Options. In lieu of a lump sum payment, the Trust, as owner of
          ---------------
the Insurance may, in accordance with the procedures of the Insurer(s), elect
any of the optional modes of payment for the death proceeds as enumerated in the
Insurance and known as "settlement options." If no such election is in effect,
the beneficiary of any portion of the Insurance shall have the right to elect
such settlement option.

     10.  Named Fiduciary. For purposes of the Employee Retirement Income
          ---------------
Security Act of 1974 (P.L. 93-406), as amended, the Company is the "named
fiduciary" of the split-dollar life insurance plan for which this Agreement is
hereby designated the written plan instrument.

     11.  Allocation Of Fiduciary Responsibilities. The Named Fiduciary may
          ----------------------------------------
allocate its responsibilities for the operation and administration of this
split-dollar life insurance plan, including the designation of persons to carry
out fiduciary responsibilities under such plan. The Named Fiduciary shall effect
such allocation of its responsibilities by delivering to the Company a written
instrument signed by it that specifies the nature and extent of the
responsibilities allocated, including the persons who are designated to carry
out those fiduciary responsibilities under the plan, together with a signed
acknowledgment of their acceptance.

     12.  Plan Administrator. The Named Fiduciary is hereby designated as the
          ------------------
"Plan Administrator" of this plan.

          ---------

signed by

interests and obligations under this Agreement; provided, however, that any
assignment shall be made subject to the terms of this Agreement. The laws of the
State of Texas shall govern the construction and enforceability of this
Agreement.

     14.  Interpretation. Where appropriate in this Agreement, words used in the
          --------------
singular shall include the plural and words used in the masculine shall include
the feminine and vice versa.

     15.  Miscellaneous. The waiver by either party of a breach of any provision
          -------------
hereof will not be deemed a waiver of any succeeding breach of such provision,
or a waiver of the provision itself. The parties will not enter into any
agreement or contract with others that would tend to vary, rescind or abrogate
the provisions hereof, nor shall they hinder or interfere with, or cause to be
interfered with in any manner whatsoever, the operation of the terms of this
Agreement. Each party hereto acknowledges that any breach or attempted breach of
any provision of this Agreement will cause irreparable harm for which there is
no adequate remedy at law, and each party agrees that each of the other parties
hereto shall be entitled to specific performance and injunctive and other
equitable relief in case of any such breach or attempted breach. This Agreement
supersedes all prior agreements between the parties and contains the entire and
only agreement between them relating to the Insurance. This Agreement is
severable and if, for any reason, any provision or provisions hereof are
determined to be invalid, inoperative, or contrary to any existing or future
law, the remainder of this Agreement shall continue to be valid after giving
effect to the intent manifested by the portion held invalid or inoperative. This
Agreement shall be binding upon and inure to the benefit of the parties, their
heirs, legal representatives, successors and assigns.

                             POLICY AS COLLATERAL
                             --------------------

A.   For Value Received, the undersigned hereby assigns, transfers and sets over
     to IMCO RECYCLING INC., a Delaware corporation (herein called the
     "Assignee"), a certain interest hereinafter specified in Policy No.
     VP60627230 (herein call the "Policy") issued by Pacific Life (herein called
     the "Insurer"), upon the life of DON V. INGRAM, subject to all the terms
     and conditions of the Policy and to all superior liens, if any, which the
     Insurer may have against the Policy. The undersigned by this instrument
     agrees, and the Assignee by the acceptance of this assignment agrees, to
     the conditions and provisions herein set forth. This Assignment is entered
     into in accordance with a Split-Dollar Life Insurance Agreement by and
     between the Assignee and INGRAM FAMILY INSURANCE TRUST NO. 1 dated the same
     date as this Assignment (the "Agreement").

B.   It is expressly agreed that the following specific interest in the Policy
     (including any dividend accumulations or additions standing to the credit
     of the Policy) passed by virtue hereof:

          The Assignee shall have an interest in the Policy and any proceeds
          becoming payable under the Policy due to death, maturity, policy loan
          or surrender of the Policy to the extent of any liability arising
          under the Agreement.

C.   Except as expressly provided in paragraph D below, it is expressly agreed
     that the following specific rights are reserved and excluded from this
     assignment and do not pass by virtue hereof:

     1.   The right to collect from the Insurer any disability benefit payable
          in cash that does not reduce the amount of insurance;

     2.   The right to designate and change the beneficiary;

     3.   The right to elect any optional mode of settlement permitted by the
          Policy or allowed by the Insurer; but any designation or change of
          beneficiary or election of a mode of settlement shall be made subject
          to this assignment and to the rights of the Assignee hereunder;

     4.   The right to surrender the Policy or to obtain policy loans from the
          Insurer;

                                     - 9 -
<PAGE>

     5.   The right to elect a nonforfeiture provision, to change the
          application of dividends or to exercise any other rights privileges
          and options available under the terms of the policy to the undersigned
          as owner of the Policy; and

     6.   The right to select investment options with respect to the policy.

D.   This assignment is made and the Policy is to be held as collateral security
     under the Agreement for any and all liabilities of the undersigned to the
     Assignee, either now existing or that may hereafter arise between the
     undersigned and the Assignee (all of which liabilities secured or to become
     secured are herein called "Liabilities"). It is expressly agreed that all
     sums received by the Assignee hereunder, either in the event of death of
     the Insured, the maturity or surrender of the Policy, the obtaining of a
     loan or advance on the Policy, or otherwise, shall first be applied to the
     payment of the Liabilities. In the event that the undersigned is obligated
     to pay any amount to the Assignee under the Agreement, the Assignee shall
     be entitled to direct payment from the Insurer, and the right to direct the
     surrender of the Policy or to obtain policy loans from the Insurer in order
     to enforce its rights under the Agreement, upon written notice to the
     Insurer.

E.   The Assignee covenants and agrees with the undersigned as follows:

     1.   That any balance of the sums received hereunder from the Insurer
          remaining after payment of the then existing Liabilities, matured or
          unmatured, shall be paid by the Assignee to the persons entitled
          thereto under the terms of the Policy had this assignment not been
          executed;

     2.   That the Assignee will forward to the Insurer, upon request and
          without unreasonable delay, the Policy for endorsement of any
          designation or change of beneficiary or any election of an optional
          mode of settlement.

F.   The Insurer is hereby authorized to recognize the Assignee's claims to
     rights hereunder without investigating the reason for any action taken by
     the Assignee, or the validity or the amount of the Liabilities or the
     existence of any default herein, or the giving of any notice, or the
     application to be made by the Assignee or any amounts to be paid to the
     Assignee. The sole receipt of the Assignee for any sums received shall be a
     full discharge and release therefor to the Insurer. Checks for the sums
     payable under the policy and assigned herein shall be drawn to the
     exclusive order of the Assignee if, when, and in such amounts, as may be
     requested by the Assignee. The Insurer shall not take any notice of the

                                    - 10 -

<PAGE>

     terms of any outside agreement or of any restrictions that may be imposed
     on the Assignee thereby.

G.   The Assignee may take or release other security, may release any party
     primarily or secondarily liable for any of the Liabilities, may grant
     extensions, renewals or indulgences with respect to the Liabilities, or may
     apply to the Liabilities proceeds of the Policy hereby assigned or any
     amount received on account of the Policy by the exercise of any right
     permitted under this assignment, without resorting or regarding to other
     security.

H.   The undersigned declares that no proceedings in bankruptcy are pending
     against it and that its property is not subject to any assignment for the
     benefit of creditors.

I.   It is the intent of the undersigned to assign an interest in proceeds
     becoming payable under the Policy as security for certain advances from the
     Assignee, without giving the Assignee any incidents of ownership in the
     Policy as defined under Section 2042 of the Internal Revenue Code (and
     Regulations thereunder) presently in effect, or any successor thereto.

     Signed this 1st day of June, 1999.

     2.2  Definitional Terms; Gender and Number.  All terms defined in this Plan
          -------------------------------------
shall have the meanings set forth herein when used in any Award Agreement or
other document made or delivered pursuant to the Plan, except where the context
thereof shall otherwise require.  Except when otherwise indicated by the
context, words in the masculine gender when used in the Plan shall include the
feminine gender, the singular shall include the plural, and the plural shall
include the singular.  The words "hereof," "herein," "hereunder," and similar
terms when used in this Plan shall refer to this Plan as a whole and not to any
particular provision of the Plan.

                   SECTION 3.  ELIGIBILITY AND PARTICIPATION

     3.1  Eligibility and Participation.  Participants in the Plan shall be
          -----------------------------
selected by the Committee from among those Employees who in the opinion of the
Committee, are key employees in a position to contribute materially to the
Company's continued growth and development and to its long-term financial
success.  The Committee, upon its own action, may grant, but shall not be
required to grant, an Award to any eligible Employee of the Company or any
Subsidiary.  The Committee shall determine the amounts, terms and conditions of
each Award granted hereunder.  Awards may be granted by the Committee at any
time and from time

                                       3
<PAGE>

to time to new Participants, or to already-participating Participants, or to a
greater or lesser number of Participants, and may include or exclude previous
Participants, as the Committee shall determine. The grant of an Award shall be
evidenced by an Award Agreement setting forth such terms, provisions,
limitations and performance criteria as are approved by the Committee, but not
inconsistent with the Plan.

     Except as required by this Plan, Awards granted at different times need not
contain similar provisions.  The Committee's determinations under the Plan
(including without limitation determinations of which Employees are to receive
Awards, the form, amount and timing of such Awards, the terms and provisions of
such Awards and the Award Agreements evidencing same) need not be uniform and
may be made by the Committee selectively among Participants who receive, or are
eligible to receive, Awards under the Plan.

     Notwithstanding any other provision contained in this Plan to the contrary,
the Committee may delegate to the Chief Executive Officer of the Company from
time to time the authority to grant up to a certain number (to be designated by
the Committee from time to time) of Performance Units and/or Performance Share
Units to be awarded to eligible Employees to be chosen by the Chief Executive
Officer in his sole discretion, so long as those Employees are not at the date
of grant an officer of the Company and are not and are not likely to be a
"covered employee" (as that term is defined under Section 162(m) of the Code and
the Treasury Regulations promulgated thereunder).

                           SECTION 4.  ADMINISTRATION

     4.1  Administration.  The Committee shall be responsible for the
          --------------
administration of the Plan.  Any member of the Committee may be removed at any
time, with or without cause, by resolution of the Board in its sole discretion.
Any vacancy occurring in the membership of the Committee may be filled by
appointment by the Board.

     Plan administrative costs and expenses shall be paid by the Company.  The
Committee is authorized to interpret the Plan, to prescribe, amend, and rescind
rules and regulations relating to the Plan, to provide for conditions and
assurances deemed necessary or advisable to protect the interests of the
Company, to correct any errors or inconsistencies in and make adjustments for
mistakes or errors made in the administration of the Plan, and to make all other
determinations necessary or advisable for the administration and application of
the Plan, including but not limited to the eligibility and participation
determinations as set forth in Section 3. Notwithstanding any provision
contained herein to the contrary, the Committee may, at any time and from time
to time, in its absolute discretion (i) accelerate the date on which any Award
granted under the Plan vests, (ii) extend the date on which any Award granted
under the Plan terminates, or (iii) remove, suspend or alter the restrictions
imposed with respect to any Award granted under the Plan.  Except as otherwise
provided herein, determinations, interpretations, or other actions made or taken
by the Committee pursuant to the provisions of the Plan shall be final and
binding and conclusive for all purposes and upon all persons whomsoever,
including the Company and all Participants.

                                       4
<PAGE>

     To the extent that the Committee determines that the restrictions imposed
by the Plan preclude the achievement of the material purposes of the Awards in
jurisdictions outside the United States, the Committee will have the authority
and discretion to modify those restrictions as the Committee determines to be
necessary or appropriate to conform to applicable requirements or practices of
jurisdictions outside of the United States.

                          SECTION 5.  DURATION OF PLAN

     5.1  Duration of Plan.  The Plan shall remain in effect, subject to the
          ----------------
Board's right to earlier terminate the Plan pursuant to Section 11 hereof, until
December 15, 2009.  Notwithstanding the foregoing, all Awards granted prior to
the date specified in the preceding sentence will continue to be effective in
accordance with their terms and conditions.

      SECTION 6.  PERFORMANCE UNIT AWARDS AND PERFORMANCE SHARE UNIT AWARDS

     6.1  Grant of Performance Unit  or Performance Share Unit Awards.  Subject
          -----------------------------------------------------------
to the provisions of this Section 6, Performance Unit Awards or Performance
Share Unit Awards may be granted to Participants at any time and from time to
time as shall be determined by the Committee.  The Committee shall have complete
discretion in determining the number of Performance Units or Performance Share
Units to be awarded to any Participant.  Any Award shall be subject to such
conditions, restrictions and contingencies (including such Performance Goals) as
the Committee shall determine.  The Performance Period shall also be determined
by the Committee and set forth in the Award Agreement.

     6.2  Performance Goals.  At the beginning of each Performance Period, the
          -----------------
Committee shall (i) establish for each Performance Period the specific
Performance Goals as the Committee believes are relevant to the Company's
overall business objectives; (ii) determine the value of a Performance Unit or a
Performance Share Unit relative to the Performance Goals; and (iii) instruct
senior management to notify each Participant in writing of the established
Performance Goals and the minimum, target, and maximum Performance Unit or
Performance Share Unit value for such Performance Period.

     6.3  Adjustments.  The Committee will make appropriate adjustments to
          -----------
exclude the effect of extraordinary corporate transactions, such as
acquisitions, divestitures, recapitalizations and reorganizations, and will not
take into account extraordinary or non-recurring accounting charges and items,
insofar as they would otherwise affect the results under the applicable
Performance Goals.

     6.4  Payment.  Upon completion of the Performance Period, the Committee
          -------
shall certify the level of the Performance Goals attained and the amount of the
Award payable as a result thereof.  The basis for payment of each Performance
Unit or Performance Share Unit for a given Performance Period shall be the
achievement of those Performance Goals determined by the Committee at the
beginning of the Performance Period.  If minimum performance is not

                                       5
<PAGE>

achieved for a Performance Period, no payment shall be made, the Performance
Unit Award or Performance Share Unit Award will terminate and all contingent
rights thereunder shall cease. If minimum performance is achieved or exceeded,
the value of a Performance Unit or Performance Share Unit shall be based on the
degree to which actual performance met or exceeded the pre-established minimum
performance standards, as determined by the Committee. The amount of payment
shall be determined by multiplying the number of Performance Units or
Performance Share Units granted at the beginning of the Performance Period times
the final Performance Unit or Performance Share Unit value. Payments shall be
made in cash following the close of the applicable Performance Period.

     6.5  Deferral.  If the terms of the particular Award granted by the
          --------
Committee so provide, the Participant may be provided an option to defer payment
of the Participant's vested Performance Unit Award or Performance Share Unit
Award.

     6.6  Termination of Employment Due To Death, Disability or Retirement.  In
          ----------------------------------------------------------------
the case of death, Disability, or Retirement, the holder of a Performance Unit
or Performance Share Unit (or his beneficiary, as the case may be) shall be
entitled to receive following the end of the particular Performance Period, a
pro rata payment based on the number of months' service during the Performance
Period, and the level of achievement of Performance Goals during the Performance
Period, to be determined by the Committee following the end of the Performance
Period.

     6.7  Termination of Employment Other Than Death, Disability or Retirement.
          --------------------------------------------------------------------
Except in circumstances in which a Change in Control is involved pursuant to
Section 9 hereof, in the event that a Participant terminates employment with the
Company for any reason other than death, Disability or Retirement, all
Performance Unit Awards and Performance Share Unit Awards shall be forfeited.

     6.8  Funding.  No provision of the Plan shall require the Company, for the
          -------
purpose of satisfying any obligations under the Plan, to purchase assets or
place any assets in a trust or other entity to which contributions are made or
otherwise to segregate any assets in a manner that would provide any Participant
any rights that are greater than those of a general creditor of the Company, nor
shall the Company maintain separate bank accounts, books, records or other
evidence of the existence of a segregated or separately maintained or
administered fund if such action would provide any Participant with any rights
that are greater than those of a general creditor of the Company.  Participants
shall have no rights under the Plan other than as unsecured general creditors of
the Company.  However, the Company may establish a "Rabbi Trust" for purposes of
securing the payment pursuant to a Change in Control.

     6.9  Nontransferability.  Performance Units or Performance Share Units
          ------------------
granted under the Plan may not be sold, transferred, pledged, assigned, or
otherwise alienated or hypothecated, other than by will or by the laws of
descent and distribution until the termination of the applicable Performance
Period.  All rights with respect to Performance Unit Awards and Performance
Share Unit Awards granted to a Participant under the Plan shall be exercisable
during his lifetime only by such Participant.

                                       6
<PAGE>

     6.10 Restrictions on Awards.  It is intended that the Plan will provide
          ----------------------
Participants with opportunities for long-term incentive compensation which is
not subject to the deduction limitation rules prescribed under Section 162(m) of
the Code, and that the Plan be construed to the degree possible as providing for
remumeration which is "performance-based compensation" within  the meaning of
Section 162(m) of the Code and the Treasury Regulations promulgated thereunder.
Notwithstanding the foregoing, the Committee may grant Awards to non-officers
and individuals who are not and are likely not to be "covered employees" as that
term is defined under Section 162(m) and the Treasury Regulations, which Awards
may thereby not meet the requirements of being "performance-based compensation."
In order for Awards to be "performance-based compensation," the grant of the
Awards and the establishment of the Performance Goals shall be made during the
period required under Section 162(m) of the Code.

     6.11 Maximum Amount.  No Participant may receive during any fiscal year of
          --------------
the Company, payment of Awards covering an aggregate of more than 300% of the
target amount designated in the Participant's Award Agreement, which amount must
be based on maximum achievement of Performance Goals and certified by the
Committee.  In addition, and in any event, no Participant may receive during any
fiscal year payment of Awards totaling in excess of $4,500,000.

                      SECTION 7.  BENEFICIARY DESIGNATION

     7.1  Beneficiary Designation.  Each Participant under the Plan may name,
          -----------------------
from time to time, any beneficiary or beneficiaries (who may be named
contingently or successively) to whom any benefit under the Plan is to be paid
in the event of such Participant's death before such Participant receives any or
all of such benefit.  Each designation will revoke all prior designations by the
same Participant, shall be in a form prescribed by the Committee, and will be
effective only when filed by the Participant in writing with the Committee
during his lifetime.  In the absence of any such designation, benefits remaining
unpaid at the Participant's death shall be paid to his estate.

                        SECTION 8.  RIGHTS OF EMPLOYEES

     8.1  Employment.  Nothing in the Plan shall interfere with or limit in any
          ----------
way the right of the Company to terminate any Participant's employment at any
time or confer upon any Participant any right to continue in the employ of the
Company.

     8.2  Participation.  No Employee shall have a right to be selected as a
          -------------
Participant or, having been so selected, to be selected again as a Participant.

                         SECTION 9.  CHANGE IN CONTROL

     9.1  In General.
          ----------

     (a)  Notwithstanding any other provision contained herein, in the event of
          a Change in Control, as defined in Section 9.2 below, affecting the
          Company in which the outstanding Awards granted by the Company prior
          to such Change in Control (and the Company's obligations in connection
          therewith) are not fully assumed by the Company after the Change in
          Control or the corporation or entity resulting from the Change in
          Control, or replaced by fully equivalent substitute Awards, then all
          outstanding Awards shall automatically be accelerated and become fully
          vested, whereupon all Performance Unit Awards and Performance Share
          Unit Awards shall be paid based upon the extent to which Performance
          Goals during the Performance Period have been met up to the date of
          the Change in Control, but in any event, not less than the target
          Award amount as set forth in each Participant's Award Agreement.

     (b)  If there is a Change in Control of the Company in which the
          outstanding Awards granted by the Company prior to such Change in
          Control (and the Company's obligations in connection therewith) are
          fully assumed by the Company after the Change in Control or the
          corporation or other legal entity resulting from the Change in
          Control, or replaced by fully equivalent substitute Awards, then,
          except as otherwise provided in this Section 9, no acceleration of
          vesting of any unmatured installments of outstanding Awards granted by
          the Company shall occur.

     (c)  In addition, notwithstanding any other provision contained in this
          Plan, in the event that a Participant's employment is terminated by
          the Company, within that period commencing on the date which is ninety
          (90) days prior to and continuing during the 24-month period following
          the effective date of a Change in Control (i.e., with such period
          ending on the same day of the 24th month following the effective date
          of the Change in Control), for any reason (other than such
          Participant's (i) voluntary resignation (which does not constitute a
          Resign for Good Reason resignation), (ii) termination as a result of
          death,  Disability or Retirement, or (iii) termination by the Company
          for Cause), or such Participant Resigns for Good Reason within such
          period, then to the extent the Awards granted to such Participant have
          not already become fully vested pursuant to this Section 9, all
          outstanding Awards granted by the Company to such Participant shall,
          without further action by any person, immediately become fully vested
          in full, effective as of the date of such termination of employment,
          whereupon all Performance Unit Awards and Performance Share Unit
          Awards shall be paid out based upon the higher of the targeted
          Performance Goals or the extent to which the Performance Goals during
          the Performance Period have been met up to the date of the Change in
          Control or the date of termination (whichever date results in the
          then-higher value of the particular Award).

     9.2  Definition.  For purposes of the Plan, a "Change in Control" shall
          ----------
mean the occurrence of any of the following events:  (i) there shall be
consummated any merger or consolidation pursuant to which shares of the
Company's Stock would be converted into or exchanged for cash, securities or
other property, or any sale, lease, exchange or other disposition (excluding
disposition by way of mortgage, pledge or hypothecation), in one transaction or
a series of related transactions, of all or substantially all of the assets of
the Company (a "Business Combination"), in each case unless, following such
Business Combination, all or substantially all of the holders of the outstanding
Stock immediately prior to such Business Combination beneficially own, directly
or indirectly, more than 50.1% of the outstanding common stock or equivalent
equity interests of the corporation or entity resulting from such Business
Combination (including, without limitation, a corporation 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) in substantially the
same proportions as their ownership, immediately prior to such Business
Combination, of the outstanding Stock, (ii) the stockholders of the Company
approve any plan or proposal for the complete liquidation or dissolution of the
Company, (iii) any "person" (as such term is defined in Section 3(a)(9) or

individuals who, at the beginning of such period constituted the entire Board,
cease for any reason (other than death) to constitute a majority of the
directors, unless the election, or the nomination for election, by the Company's
stockholders, of each new director was approved by a vote of at least a majority
of the directors then still in office who were directors at the beginning of the
period.

          SECTION 10.  AMENDMENT, MODIFICATION,AND TERMINATION OF PLAN

     10.1 Amendment, Modification, and Termination of Plan.  The Board at any
          ------------------------------------------------
time may terminate, and from time to time may amend or modify the Plan,

permitted by this Section 11.1 shall reduce the amount of any Award theretofore
granted under the Plan without the consent of the affected Participant.

          ---------------
the Committee or of the Board, or who acts on behalf of or at the direction of

harmless by the Company against and from any loss, cost, liability, or expense
that may be imposed upon or reasonably incurred by him in connection with or
resulting from any claim, action, suit, or proceeding to which he may be a party
or in which he may be involved by reason of any action taken or failure to act
under the Plan and against and from any and all amounts paid by him in
settlement thereof, with the Company's approval, or paid by him in satisfaction
of any judgment in any such action, suit, or proceeding against him, provided he

foregoing right of indemnification shall not be exclusive of any other rights of
indemnification to which such persons may be entitled under the Company's
Certificate of Incorporation or Bylaws, as a matter of law, or otherwise, or any

conditions set forth in this Plan to such extent as the Committee or Board at
the time of grant may deem appropriate to conform, in whole or in part, to the
provisions of the incentives  in substitution for which they are granted.
