                              IMCO RECYCLING INC.

                               RESTRICTED STOCK
                                AWARD AGREEMENT

     This RESTRICTED STOCK AWARD AGREEMENT (the "Agreement") is entered into
effective as of the Date of Grant by and between Don V. Ingram (the "Executive")
and IMCO Recycling Inc., a Delaware corporation ("IMCO").

                               WITNESSETH THAT:
                               ---------------

     WHEREAS, IMCO Management Partnership L.P. (the "Company"), IMCO and the
Executive are parties to that certain Employment Agreement dated effective as of
September 1, 2000 (the "Employment Agreement") whereby IMCO agreed, subject to
and in accordance with the terms hereof, that IMCO would grant an award to the
Executive of shares of restricted common stock of IMCO ("Restricted Stock"),
with respect to which the restrictions on ownership and disposition would lapse
upon, among other events and occurrences, the second anniversary of the date of
the occurrence of a "Change in Control" (as that term is defined in the
Employment Agreement);

     NOW, THEREFORE, IT IS AGREED, by and between IMCO and the Executive, as
follows:

     1.  Terms of Award. The following terms used in this Agreement shall have
         --------------
the meanings set forth in this paragraph 1:

     The "Date of Grant" is October 12, 2000.

     The number of shares of "Restricted Stock" awarded under this Agreement is
     400,000 shares.

     The "Restriction Period" is the period commencing the Date of Grant and
     ending on that day which is the second anniversary date of the date of the
     Change in Control, provided that the Executive has not sooner experienced a
     Termination of Service (as defined below) prior to such date.

     "Termination of Service" shall be deemed to occur on the Termination Date.
<PAGE>

Other capitalized terms appearing in this Agreement which are not otherwise
defined in this Agreement shall have the respective terms assigned to them as
set forth in the Employment Agreement.

     2.  Award. The Executive is hereby granted by IMCO the number of shares
         -----
of Restricted Stock set forth in paragraph 1 (the "Award").  Such grant of
shares of Restricted Stock shall only be made from shares of authorized and
issued shares of IMCO common stock held in IMCO's treasury, and not from
authorized and unissued shares.  It is hereby understood and agreed that in the
event of a Change in Control, all of the Executive's previously unexercised and
outstanding stock options granted to him by IMCO prior to the Date of Grant (as
more particularly described on Appendix A which is attached hereto and made a
part hereof) shall thereupon terminate and be cancelled and rendered null and
void and of no further effect.

     3.  Dividends and Voting Rights. Until the date of the Change in Control,
         ---------------------------
the Executive shall not be entitled to receive any dividends with respect to
shares of Restricted Stock that become payable during the Restriction Period and
no dividends shall accrue with respect thereto; provided, however, that
dividends shall be payable to or for the benefit of the Executive with respect
to record dates for such dividends occurring after the date of the Change in
Control and prior to the date (if any) on which the Executive has forfeited the
Restricted Stock. The Executive shall be entitled to vote the shares of
Restricted Stock during the Restriction Period to the same extent as would have
been applicable to the Executive if the Executive was then vested in the shares;
provided, however, that the Executive shall not be entitled to vote the shares
with respect to record dates occurring prior to the Date of Grant, or with
respect to record dates occurring on or after the date (if any) on which the
Executive has forfeited the Restricted Stock.

     4.  Deposit of Shares of Restricted Stock. Each certificate issued in
         -------------------------------------
respect of shares of Restricted Stock granted under this Agreement shall be
registered in the name of the Executive but shall remain in the custody of IMCO
or the Company until all restrictions on such Restricted Stock have lapsed and
the Restriction Period for such shares of Restricted Stock has expired.

     5.  Transfer and Forfeiture of Shares. Subject to the terms hereof, shares
         ---------------------------------
of Restricted Stock may not be sold, assigned, transferred, pledged or otherwise
encumbered until the expiration of the Restriction Period. Except as otherwise
expressly provided in paragraph 6, if the Termination of Service occurs

                                       2
<PAGE>

prior to the end of the Restriction Period, the Executive shall forfeit the
shares of Restricted Stock effective as of the Termination of Service.

     6.  Vesting. If there has not been a Termination of Service during the
         -------
Restriction Period, then upon the expiration of the Restriction Period, the
Executive shall become 100% vested in the shares of Restricted Stock awarded
hereunder, and shall own those shares free of all restrictions otherwise imposed
by this Agreement. In addition, the Executive shall also become fully vested in
all of the shares of Restricted Stock awarded hereunder prior to the end of the
Restriction Period, and become owner of such shares free of all restrictions
otherwise imposed by this Agreement, as follows:

         (a)  The Executive shall become fully vested in all of the shares of
     Restricted Stock awarded hereunder as of the date of the Executive's
     Termination of Service, if such Termination of Service occurs on or after
     that date which is 90 days prior to the date of the Change in Control by
     reason of the Executive's death, Total Disability or retirement in
     accordance with Company policies concerning executive retirement as in
     effect on September 1, 2000; or

         (b)  The Executive shall become fully vested in all of the shares of
     Restricted Stock awarded hereunder as of the date of the Termination of
     Service, if the Executive is Terminated Without Cause or the Executive
     Resigns for Good Reason at any time on or after that date which is 90 days
     prior to the Change in Control; or

         (c)  The Executive shall become fully vested in all of the shares of
     Restricted Stock awarded hereunder upon the occurrence of a Change in
     Control and the obligations of IMCO under this Agreement with respect to
     the Award are not fully assumed or replaced by equivalent substitute
     award(s), as more fully described in paragraph 7 below; or

         (d)  If in connection with a Change of Control the obligations of IMCO
     under this Agreement with respect to the Award are assumed or equivalent
     substitute award(s) are granted in lieu thereof, but a subsequent Change in
     Control occurs before the expiration of the Restriction Period, then
     effective upon such subsequent Change in Control, the Executive shall
     become fully vested in all of the shares of Restricted Stock awarded
     hereunder, as more fully described in paragraph 7 below.

                                       3
<PAGE>

     7.  Assumption Following Change in Control. If there occurs a Change in
         ---------------------------------------
Control under which the obligations of IMCO with respect to the outstanding
Award under this Agreement are not assumed, or such Award is not replaced by
equivalent substitute award(s) by IMCO or IMCO's Successor (as defined below),
then the Restriction Period applicable to all shares of Restricted Stock granted
under this Agreement shall thereupon automatically terminate, and IMCO or the
Company shall provide reasonable prior written notice to the Executive of the
date such Restriction Period will so expire.

     In the event of any Change in Control prior to the expiration of the
Restriction Period, but subsequent to the date of a previous Change in Control
with respect to which the obligations of IMCO regarding the outstanding Award
under this Agreement were fully assumed by IMCO or IMCO's Successor or such
Award was replaced by equivalent substitute award(s), then, notwithstanding any
provision to the contrary contained in this Agreement, the Restriction Period
applicable to all shares of Restricted Stock granted under this Agreement shall
thereupon automatically terminate, and the Company and IMCO or IMCO's Successor
shall provide reasonable prior written notice to the Executive of the date such
Restriction Period will so expire.

     As used herein, the term "IMCO" shall mean IMCO as hereinbefore defined,
and "IMCO's Successor" shall mean any successor to IMCO's business or assets as
aforesaid which executes and delivers an agreement to assume IMCO's obligations
under this Agreement or which otherwise becomes bound by all of the terms and
provisions hereof by operation of law.

     8.  Heirs and Successors. This Agreement shall be binding upon, and inure
         --------------------
to the benefit of, IMCO and its successors and assigns, and upon any person
acquiring, whether by merger, consolidation, purchase of assets or otherwise,
all or substantially all of IMCO's assets and business. Any benefits
distributable to the Executive under this Agreement that are not distributed at
the time of the Executive's death shall be distributed at the time and in the
form determined in accordance with the provisions of this Agreement and the
Employment Agreement to the beneficiary designated by the Executive in writing
filed with the Company or IMCO in such form and at such time as the Company or
IMCO shall require. If a deceased Executive has failed to designate a
beneficiary, or if the designated beneficiary of the deceased Executive dies
before the Executive or before complete distribution of benefits due under this
Agreement, the amounts to be distributed under this Agreement shall be

                                       4
<PAGE>

distributed to the legal representative or representatives of the estate of the
last to die of the Executive and the beneficiary.

     9.  Administration. The authority to manage and control the administration
         --------------
of this Agreement shall be vested in the Compensation Committee of the Board of
Directors.

     10. Amendment. This Agreement may be amended only by written agreement of
         ---------
the Executive and IMCO, without the consent of any other person.

     11. Adjustments. Except as otherwise expressly provided in this Agreement,
         -----------
the issuance by IMCO (or IMCO's Successor) of shares of its capital stock of any
class, or securities convertible into shares of capital stock of any class,
either in connection with direct sale or upon the exercise of rights, options,
or warrants to subscribe therefor, or upon conversion of shares or obligations
of IMCO or IMCO's Successor convertible into such shares or other securities,
shall not affect, and no adjustment by reason thereof shall be made with respect
to, the number of outstanding shares of Restricted Stock.

     12. Recapitalization, Merger and Consolidation; Change in Control.
         -------------------------------------------------------------

         (a)  The existence of this Agreement and the Award granted hereunder
     shall not affect in any way the right or power of IMCO or its stockholders
     to make or authorize any or all adjustments, recapitalizations,
     reorganizations, or other changes in IMCO's capital structure and its
     business, or any merger or consolidation of IMCO, or any issue of bonds,
     debentures, preferred or preference stocks ranking prior to or otherwise
     affecting the Common Stock or the rights thereof (or any rights, options,
     or warrants to purchase same), or the dissolution or liquidation of IMCO
     or, or any sale or transfer of all or any part of its assets or business,
     or any other corporate act or proceeding, whether of a similar character or
     otherwise.

         (b)  Subject to any required action by the stockholders (and except as
     otherwise provided in sub-paragraph (c) below), if IMCO shall be the
                           -----------------
     surviving or resulting corporation in any merger, consolidation or share
     exchange, the Award granted hereunder shall pertain to and apply to the
     securities or rights (including cash, property, or assets) to which a
     holder of the number of shares of Common Stock subject to the Award would
     have been entitled.

                                       5
<PAGE>

         (c)  In the event of any merger, consolidation or share exchange
     pursuant to which IMCO is not the surviving or resulting corporation, (or
     IMCO is the surviving entity but the Common Stock of IMCO is exchanged for
     cash, property, securities or other consideration of or from any other
     entity) there shall be substituted for each share of Common Stock subject
     to this Award, (i) that number of shares of each class of stock or other
     securities or that amount of cash, property, or assets of the surviving,
     resulting or consolidated entity which were distributed or distributable to
     the stockholders of IMCO in respect of each share of Common Stock held by
     them, or (ii) such number of shares of stock, or other securities, or such
     amount of cash, property or assets (or any combination thereof) as
     proportionate in value as reasonably practicable to the consideration
     distributed or distributable to the stockholders of IMCO with respect to
     each share of Common Stock held by them.

         (d)  In case IMCO shall, at any time while this Award is outstanding
     and the Restriction Period remains unexpired, (i) sell all or substantially
     all of its property, or (ii) dissolve, liquidate, or wind up its affairs,
     then the Executive shall be thereafter entitled to receive, in lieu of each
     share of Common Stock which the Executive would have been entitled to
     receive under the Award, the same kind and amount of any securities or
     assets as may be issuable, distributable, or payable upon any such sale,
     dissolution, liquidation, or winding up with respect to each share of
     Common Stock of IMCO.

     13. Investment Intent. IMCO may require that there be presented to and
         -----------------
filed with it such evidence as it may deem necessary to establish that the
shares of Common Stock to be transferred to the Executive are being acquired for
investment purposes only and not with a view to their resale or distribution.

     14. No Right to Continued Employment.  This Agreement shall not confer upon
         --------------------------------
the Executive any right with respect to continuance of employment by the Company
or any other company in the IMCO Group (as that term is defined in the
Employment Agreement).

     15. Compliance With Other Laws and Regulations. The grant of the Award and
         ------------------------------------------
the obligation of IMCO to deliver shares of Common Stock hereunder, shall be
subject to all applicable federal and state laws, rules and regulations and to
such approvals by any government or regulatory agency as may be required. In

                                       6
<PAGE>

the event it is determined that any such grant, issuance or delivery for any
reason violates any law, rule or regulation, then the Award shall thereupon
automatically convert to a phantom restricted stock award or other similar
equivalent award, having a value substantially equivalent to the value of the
Award, and payable in cash instead of Common Stock. Such award will be
exercisable at any time the Executive may elect on or after the date such award
becomes fully vested in accordance with the vesting terms applicable to the
Award granted hereunder (but at any rate not more than three years after full
vesting occurs.)

     16. Tax Requirements. IMCO or the Company shall have the right to deduct
         ----------------
any Federal, state, or local taxes required by law to be withheld with respect
to the Award hereunder. The Executive receiving shares of Common Stock issued
under this Agreement shall be required to pay IMCO or the Company the amount of
any taxes which IMCO or the Company is required to withhold with respect to such
shares of Common Stock.

     17. Legend. Each certificate representing shares of Restricted Stock issued
         ------
to the Executive shall bear the following legend, or a similar legend deemed by
IMCO to constitute an appropriate notice of the provisions hereof (any such
certificate not having such legend shall be surrendered by the Executive upon
demand by IMCO and so endorsed):

         On the face of the certificate:

         "Transfer of this stock is restricted in accordance with conditions
         printed on the reverse of this certificate."

         On the reverse:

         "The shares of stock evidenced by this certificate are
         subject to and transferable only in accordance with the terms
         of the IMCO Recycling Inc. Restricted Stock Award Agreement
         dated October 12, 2000, a copy of which is on file at the
         principal executive offices of IMCO Recycling Inc. in Irving,
         Texas. No transfer or pledge of the shares evidenced hereby
         may be made except in accordance with and subject to the
         provisions of said Agreement. By acceptance of this
         certificate, any holder, transferee or pledgee hereof agrees
         to be bound by all of the provisions of said Agreement."

                                       7
<PAGE>

     The following legend shall be inserted on each certificate evidencing
Common Stock issued hereunder if the shares were not issued in a transaction
registered under the applicable federal and state securities laws:

          "Shares of stock represented by this certificate have been
          acquired by the holder for investment purposes only and not
          for resale, transfer or distribution, have been issued
          pursuant to exemptions from the registration requirements of
          applicable state and federal securities laws, and may not be
          offered for sale, sold or transferred other than pursuant to
          effective registration under such laws, or in transactions
          otherwise in compliance with such laws, and upon evidence
          satisfactory to IMCO Recycling Inc. of compliance with such
          laws, as to which IMCO Recycling Inc. may rely upon an
          opinion of counsel satisfactory to IMCO Recycling Inc."

     IN WITNESS WHEREOF, the Executive has executed this Agreement, and IMCO has
caused this Agreement to be executed in its name and on its behalf, all
effective as of the Date of Grant.

     WHEREAS, the Company performs management and administrative services for
IMCO Recycling Inc. ("IMCO") and IMCO's subsidiaries and affiliates (hereinafter
IMCO and IMCO's subsidiaries and affiliates are collectively referred to as the

Engagement");

     WHEREAS, the Company has employed the Executive to devote his full time,
attention and energies in performing the specific duties assigned to him with
respect to the IMCO Engagement and such other duties as the Company may assign
him to perform;

     WHEREAS, as part of the IMCO Engagement, the Executive has been assigned
the duties and elected to the position of Executive Vice President and Chief
Financial Officer of IMCO;

     WHEREAS, the Company and IMCO consider an agreement related to the
employment of the Executive to be in the best interests of the Company and vital
to the IMCO Engagement;

     WHEREAS, if the Executive's employment is terminated during the Term of
this Agreement, the Company also desires to retain the Executive's services in
an advisory and consulting capacity and to prevent any other business
competitive with IMCO, the IMCO Group or the Company from securing his services
and utilizing his experience, background and expertise during the post

Executive agrees that he must not delegate any or all of his duties or
obligations under this agreement except as may be authorized by the Company, the
CEO or the Board of Directors.

Article III.

     (b)  "Confidential Information" means all proprietary information of a
special unique nature and value to IMCO, the IMCO Group, or the Company and all
other information of any kind, nature, type, or description that is important,
confidential or otherwise concerns any material matter affecting or relating to
the business of IMCO, the IMCO Group, or the Company, whether or not developed,

or the Company.  When used or referred to in this Agreement, Confidential
Information does not include any information that is now in, or hereafter comes
into, the public domain through no act or omission of the Executive; any

source other than IMCO, the IMCO Group, or the Company as of the date of the
disclosure as evidenced by the Executive's written documentation; or information

     (c)  "Cause" means (i) a willful failure or refusal by the Executive to
follow the reasonable instructions of the Board of Directors or CEO; (ii) a
theft, embezzlement, or a willful commission by the Executive of any other acts
that are dishonest and materially injurious to IMCO or the IMCO Group; (iii) the

physician will make the determination whether the Executive suffers from a Total
Disability.  In the absence of fraud or bad faith, the determination of such
physician will be final and binding on the Company, IMCO and the Executive.  The
entire cost of any such examination will be borne by the Company.  Also, failure
to comply with the Board of Directors' request to submit to a physical and/or
mental examination shall prevent the Executive from challenging the Board of
Directors' decision that the Executive suffers from a Total Disability.

diminution in the position or status of the Executive with the Company or IMCO
immediately prior to said action, except in connection with a termination of the
Executive's employment as a result of the Executive's Total Disability or for
Cause; (ii) an assignment of the Executive by the Company or IMCO to
inappropriate duties; (iii) a transfer or proposed transfer of Executive for a
consecutive period in excess of six months to a location outside the Dallas/Fort
Worth, Texas metropolitan area, without the Executive's prior written consent;
(iv) the Company (A) reduces the annual base salary of the Executive, or (B)
modifies in any respect the formula or method of calculation of the "target
incentive award" (or any successor equivalent amount) for the Executive (as
previously determined for the Executive for that particular fiscal year) which
modification would result in such target incentive award amount (or any such
equivalent amount) being reduced, in either case without the Executive's prior
written consent; (v) the failure of the Company or IMCO to obtain the express
written assumption and agreement to timely perform the Company's obligations
under this Agreement by any successor to the Company as required by Article IX;

in writing by the Executive.  Notwithstanding anything else to the contrary
herein, the Executive may not Resign for Good Reason for the occurrences
identified in this Section 5.1(e)(i), (ii), (iii), (iv), or (vii), unless the

                                       6
<PAGE>

Company has failed to cure the violation after the Executive has given the
Company written notice identifying the violation. The Company shall have five
(5) days from receipt of the written notice to cure the violation or, if the
violation requires a longer period to cure, the Company pursues a course of
action that causes the default to be cured within a reasonable period of time. A
determination by the Executive that he may Resign for Good Reason shall be
conclusive if made in good faith.

     (f)  "Change in Control" means the occurrence of any of the following
events:

          (i)   An acquisition of any voting securities of IMCO (the "Voting
     Securities") by any "person" (as the term person is used for purposes of
     Section 13(d) or Section 14(d) of the Securities Exchange Act of 1934, as
     amended (the "Exchange Act")), immediately after which such Person has
     "Beneficial Ownership" (within the meaning of Rule 13d-3 promulgated under
     the Exchange Act) of twenty-five percent (25%) or more of the combined
     voting power of IMCO's then outstanding Voting Securities; provided,
     however, in determining whether a Change in Control has occurred, Voting
     Securities which are acquired in a "Non-Control Acquisition" (as
     hereinafter defined) shall not constitute an acquisition which would cause
     a Change in Control.  A "Non-Control Acquisition" shall mean an acquisition
     by (1) an employee benefit plan (or a trust forming a part thereof)
     maintained by (A) IMCO or (B) any corporation or other Person of which a
     majority of its voting power or its voting equity securities or equity
     interest is owned, directly or indirectly, by IMCO (for purposes of this
     definition, a "Subsidiary") (2) IMCO or its Subsidiaries, or (3) any Person
     in connection with a "Non-Control Transaction" (as hereinafter defined);

          (ii)  The individuals who, as of date agreement is approved by the
     Board of Directors are members of the Board of Directors (the "Incumbent
     Board"), cease for any reason to constitute at least two-thirds of the
     members of the Board of Directors; provided, however, that if the election,
     or nomination for election by IMCO's common stockholders, of any new
     director was approved by a vote of at least two-thirds of the Incumbent
     Board, such new director shall, for purposes of this Plan, be considered as
     a member of the Incumbent Board; provided further, however, that no
     individual shall be considered a member of the Incumbent Board if such
     individual initially assumed office as a result of either an actual or
     threatened "Election Contest" (a solicitation by any Person for the purpose
     of opposing a solicitation by the Board of Directors with respect to the
     election or removal of directors at any annual or special meeting of
     stockholders of IMCO) or other actual or threatened solicitation of proxies
     or consents by or on behalf of a Person other than the Board of Directors
     (a "Proxy Contest") including by reason of any agreement intended to avoid
     or settle any Election Contest or Proxy Contest; or

          (iii) Approval by the stockholders of IMCO of:

               (1) A merger, consolidation or reorganization involving IMCO,
     unless such merger, consolidation or reorganization is a "Non-Control
     Transaction."  A "Non-Control Transaction" shall mean a merger,
     consolidation or reorganization of IMCO where:

                                       7
<PAGE>

                    (A) the stockholders of IMCO, immediately before such
          merger, consolidation or reorganization, own directly or indirectly
          immediately following such merger, consolidation or reorganization, at
          least fifty-five percent (55%) of the combined voting power of the
          outstanding voting securities of the corporation resulting from such
          merger or consolidation or reorganization (the "Surviving
          Corporation") in substantially the same proportion as their ownership
          of the Voting Securities immediately before such merger, consolidation
          or reorganization,

                    (B) the individuals who were members of the Incumbent Board
          immediately prior to the execution of the agreement providing for such
          merger, consolidation or reorganization constitute at least two-thirds
          of the members of the board of directors of the Surviving Corporation,
          or a corporation beneficially directly or indirectly owning a majority
          of the Voting Securities of the Surviving Corporation, and

                    (C) no Person other than (i) IMCO, (ii) any Subsidiary,
          (iii) any employee benefit plan (or any trust forming a part thereof)
          maintained by IMCO, the Surviving Corporation, or any Subsidiary, or
          (iv) any Person who, immediately prior to such merger, consolidation
          or reorganization had Beneficial Ownership of twenty-five percent
          (25%) or more of the then outstanding Voting Securities), has
          Beneficial Ownership of twenty-five percent (25%) or more of the
          combined voting power of the Surviving Corporation's then outstanding
          voting securities.

               (2)  A complete liquidation or dissolution of IMCO; or

               (3)  An agreement for the sale or other disposition of all or
     substantially all of the assets of IMCO and its Subsidiaries (considered on
     a consolidated basis) to any Person (other than a transfer to a
     Subsidiary).

     Notwithstanding the foregoing, a Change in Control shall not be deemed to
occur solely because any Person (the "Subject Person") acquired Beneficial
Ownership of more than the permitted amount of the then outstanding Voting
Securities as a result of the acquisition of Voting Securities by IMCO which, by
reducing the number of Voting Securities then outstanding, increases the
proportional number of shares Beneficially Owned by the Subject Persons,
provided that if a Change in Control would occur (but for the operation of this
sentence) as a result of the acquisition of Voting Securities by IMCO, and after
such share acquisition by IMCO, the Subject Person becomes the Beneficial Owner
of any additional Voting Securities which increases the percentage of the then
outstanding Voting Securities Beneficially Owned by the Subject Person, then a
Change in Control shall occur.  For purposes of this Agreement, Change in
Control shall also be deemed to include the earlier of the execution and
delivery of a binding agreement to effect a Change in Control or the actual
occurrence as set forth above which results in the Change in Control.

                                       8
<PAGE>

     (g)  "Term of this Agreement" shall mean the period commencing with the
Effective Date and ending on the Termination Date.

     (h)  "Termination Date" means the earlier of September 1, 2002 (as such
date may be extended by any extensions hereof); or the date of the Executive's
death; or the date designated in this Agreement after the Company or the
Executive gives the required notice; or as otherwise provided in this Article V
or in Article VI.

     5.2  Death of the Executive. In the event the Executive dies during the
          ----------------------
Term of this Agreement, the Executive's employment with the Company will
automatically terminate on the date of the Executive's death.  Notwithstanding
the provisions of Article I above, in the event the Executive dies during the
Term of this Agreement, within ninety (90) days after the Termination Date, the
Executive's estate, heirs, or beneficiaries, as the case may be, will receive an
amount in cash payable in a lump sum equal to the sum of (a) the Executive's
Salary and Bonus due and payable to the Executive on or before the Termination
Date, (b) an amount equal to the product of (i) one-twelfth (1/12th) of
Executive's Salary as in effect as of the Termination Date times (ii) the lesser
of (A) the number of months remaining prior to the end of  the Term of this
Agreement, or (B) twelve (12), and (c) the value of all other outstanding
obligations of the Company or IMCO to the Executive (e.g., deferred incentive
payments or stock ownership rights) without regard as to whether they would
otherwise be due and payable as of the Termination Date.  The Executive's
estate, heirs or beneficiaries, as the case may be, will also receive any
benefits that are payable to them under the plans, policies and other provisions
set forth in Article IV and Section 6.7.

     5.3  Employment Terminated by the Company. Notwithstanding any other
          ------------------------------------
provision of this Agreement, the Company may only terminate the Executive's
employment during the Term of this Agreement in accordance with the provisions
set forth below:

     (a)  The Company may terminate the Executive's employment for Cause only if
the determination to terminate the Executive's employment for Cause is made by
an affirmative vote of at least 75% of the entire Board of Directors (not
including, for this purpose, the Executive).  If the Board of Directors makes
such a determination, the Company may then terminate the Executive's employment
for Cause.  The Termination Date will be that date which is five (5) days after
the Company has notified the Executive of the Board of Directors' decision to
terminate the Executive's employment for Cause.

     (b)  The Company may terminate the Executive's employment if he suffers
from a Total Disability for a period of more than one hundred twenty (120)
consecutive days during any twelve-month period. The Termination Date will be
thirty (30) days after the Company has notified the Executive of the Board of
Directors' decision to terminate the Executive due to a Total Disability.

     (c)  The Company, in its sole discretion, may terminate the Executive's
employment by giving him not less than thirty (30) days advance written notice
of the termination.  A termination by the Company under this Section 5.3(c)
(i.e., for any reason other than those covered under Sections 5.3(a) and (b))
shall be referred to for all purposes as being "Terminated Without Cause."

                                       9
<PAGE>

     If the Executive's employment is terminated by the Company, the Company in
the ordinary and normal course of its business is obligated to continue to pay
to the Executive, the Executive's Salary and Bonus (less applicable withholding)
that are due and payable to the Executive on or before the Termination Date.
Any unpaid amount of the Executive's Salary and Bonus will be due and payable as
of the Termination Date.  The Executive will also receive the benefits and all
other amounts that he is entitled to receive pursuant to the provisions
contained in Article IV, and any amounts that the Executive is entitled to
receive pursuant to the provisions that apply to the Executive's situation in
Article VI.

     5.4  Resignation (i.e., Termination of Employment) by Executive. If the
          ----------------------------------------------------------
Executive Resigns for Good Reason after a Change in Control, the Executive's
employment with the Company will terminate twenty-one (21) days after the
Executive has notified the Company of his resignation.  If the Executive Resigns
for Good Reason other than a situation involving a Change in Control, the
Executive's employment with the Company will terminate forty five (45) days
after the Executive has notified the Company of his resignation.  If the
Executive resigns his employment for any other reason (including retirement),
the Executive's employment with the Company will terminate sixty (60) days after
the Executive has notified the Company that he is terminating his employment.
If the Executive terminates his employment, the Company in the ordinary and
normal course of its business is obligated to continue to pay to the Executive,
the Executive's Salary and Bonus (less applicable withholding) due and payable
to the Executive on or before the Termination Date.  The Executive will also
receive the benefits and all other amounts that he is entitled to receive
pursuant to the provisions contained in Article IV and any amounts that the
Executive is entitled to receive pursuant to the provisions that apply to the
Executive's situation in Article VI.

     5.5  No Right to Set Off. Except as specifically provided in Section 6.8,
          -------------------
the Company shall not be entitled to set off against the amount payable to the
Executive any amounts earned by the Executive from other employment after the
Termination Date or any amounts which might have been earned by the Executive in
other employment had he sought such other employment.  The amounts payable to
the Executive under this Agreement shall not be treated as damages but as
compensation to which the Executive is entitled by reason of termination of his
employment in the circumstances contemplated by this Agreement.

     5.6  Executive's Remedies. The Executive's sole and exclusive remedy for
          --------------------
the termination of this Agreement prior to the end of the Term of this Agreement
regardless of whether the termination is initiated by the Company or by the
Executive, and regardless whether the termination is for Cause, will be his
rights to the payments of the amounts required to be paid to him in accordance
with the provisions of the particular Section of this Article V under which such
termination occurs.  The Executive may enforce these rights to such payments by
any cause of action against the Company or IMCO sounding in law or in equity.

     5.7  Testimony and Participation Before or After Termination. The Executive
          -------------------------------------------------------
agrees that both during and following the Term of this Agreement he will be
available to testify and/or participate in any proceeding (governmental or
otherwise) involving the Company, IMCO and/or

                                       10
<PAGE>

the IMCO Group regarding any subject matter occurring prior to the Termination
Date or of which he otherwise has actual knowledge; provided that the foregoing
                                                    --------
shall not require the Executive to provide testimony in any respect which
testimony may, in Executive's good faith belief, self-incriminate the Executive.
The Company agrees to reimburse the Executive for the reasonable costs he incurs
in connection with his testimony or participation, including reasonable attorney
fees, unless such proceeding is due to the intentional wrongdoing or willful
neglect of the Executive or to actions taken by the Executive outside of the
Executive's authority.

                                  ARTICLE VI
               ADDITIONAL COMPENSATION FOR CERTAIN TERMINATIONS
                         AND POST EMPLOYMENT SERVICES

     6.1  Purpose; General Summary; and Post Employment Activities.
          --------------------------------------------------------

     (a)  The Company and the Executive agree that the success and value of
IMCO's, the IMCO Group's and the Company's business depend largely on the
favorable reputation and good will that have been created by superior managerial
skills, market position, product technology, good customer relations, a stable
work force and high employee morale.  The Executive recognizes and expressly
acknowledges that his services are unique and extraordinary and that he plays an
integral and valuable role in sustaining and enhancing the progress, reputation
and good will of IMCO, the IMCO Group and/or the Company.

     Executive acknowledges that as of the time this Agreement is entered into,
the Company, IMCO and the IMCO Group are providing to the Executive, on an
initial and ongoing basis, now and throughout the Term of this Agreement,
Confidential Information and specialized training.  The Company and the
Executive also agree that access to IMCO's, the IMCO Group's and the Company's
customers and Confidential Information and such specialized training is
essential for the most efficient performance of the Executive's duties and
obligations.  The Executive acknowledges and expressly confirms that in the
course of his employment by the Company and in furtherance of his duties and
obligations as an executive officer of IMCO, the Executive has developed
valuable banking and financial, customer and other key relationships and has
acquired (and will continue to acquire) valuable Confidential Information that
would be useful to IMCO's, the IMCO Group's and/or the Company's competitors
and, if so disclosed, would unreasonably harm the business of IMCO, the IMCO
Group and/or the Company.

     The Executive further acknowledges and specifically agrees he must at all
times act in a manner that would augment the reputation and good will of IMCO,
the IMCO Group and the Company and that it is in the best interest of the
Company and the Executive for the parties to reach a mutual agreement under
which the Executive's employment and post-employment activities are subject to
certain restrictions as a means of securing and protecting the reputation, good
will, Confidential Information and other valuable protectable interests of IMCO,
the IMCO Group and/or the Company.

                                       11
<PAGE>

     (b)  If the Executive resigns or terminates his employment for any reason
or the Executive's employment is terminated by the Company at any time during
the Term of this Agreement, the Company and the Executive expressly agree that
the Executive will be retained by the Company for a twenty-four month period
following the termination of his employment to provide services in an advisory
and consulting capacity and to prevent any other business competitive with IMCO,
the IMCO Group or the Company from securing his services and utilizing his
experience, background and expertise. During this period, the Executive shall
receive, as additional compensation, the payments enumerated in this Article VI
in exchange for the Executive's agreement to continue to actively promote,
support, consult with and advise the Company during the said twenty-four month
period. The Executive further agrees to abide by and be subject to the
restrictions as set forth in Article VII regardless of whether the Executive is
entitled to any of the payments enumerated in this Article VI.

     (c)  The Executive also acknowledges, agrees, and warrants for all purposes
that the restrictions imposed on his employment and post employment activities
contained in this Article VI and Article VII are reasonable and necessary for
the protection of the good will, reputation, Confidential Information and other
valuable protectable interests of IMCO, the IMCO Group and/or the Company and
that the additional compensation the Executive will receive, enumerated in this
Article VI, is fair and reasonable.

     6.2  Termination Without Cause; Executive Resigns for Good Reason Involving
          ----------------------------------------------------------------------
a Change of Control; Executive Resigns After One Year After a Change in Control.
-------------------------------------------------------------------------------
If during the Term of this Agreement Executive is Terminated Without Cause
before that date which is 90 days prior to a Change in Control, the Executive
will receive an amount equal to 2.0 times the Executive's "Base Amount" (as that
term is defined in Section 280G of the Internal Revenue Code of 1986, as amended
(the "Code")) (the "Base Amount"), calculated as of the Termination Date.  If
during the Term of this Agreement (i) the Executive is Terminated Without Cause
on or after that date which is 90 days before a Change in Control, or (ii) the
Executive Resigns for Good Reason during the period which begins on that date
which is 90 days before a Change in Control and ends on that date which is the
second anniversary date of such Change in Control, or (iii) the Executive's
employment is terminated by the Company or by the Executive or notice of such
termination is given for any reason (including by the voluntary resignation of
the Executive) other than for Cause, or for death or Total Disability, within
the 30-day period which begins upon the first anniversary date of a Change in
Control, then in any of such events, the Executive shall be entitled to receive
an amount equal to 2.99 times (x) the Executive's Base Amount calculated as of
the Termination Date.

     The amounts described in this Section 6.2 shall be in addition to the
Salary and Bonus due and payable on or before the Termination Date and all other
payments and benefits the Executive is entitled to receive under this Agreement.
Except in the situation where the Executive is Terminated Without Cause, the
additional compensation will be paid in a lump sum on or before the Termination
Date in accordance with the normal payroll procedures for a lump sum payment, as
the same may be modified from time to time.  If the Executive is Terminated
Without Cause (whether prior to or after a Change in Control), the additional
compensation will be paid in equal monthly installments over a twenty-three
month period following the Termination Date as if the Executive's

                                       12
<PAGE>

employment had continued hereunder payable in accordance with the normal payroll
procedures, as the same may be modified from time to time. In addition:

     (a)  For the lesser of (1) a period of eighteen (18) months subsequent to
the Termination Date or (2) until the Executive obtains comparable coverage
under a subsequent employer's benefit plan or plans, IMCO will pay all of the
cost incurred by the Executive for his continued participation in IMCO's
Benefits Plan provided that his continued participation is permitted under the
general terms and provisions of the applicable plan, program and/or policy that
is included in IMCO's Benefits Plan.  In the event the Executive's participation
in the Group Life and Accidental Death and Dismemberment Insurance Program for
Senior Management, the applicable Group Long Term Disability Insurance Program,
the major medical plan which includes hospital, physician, prescription drugs
and dental benefits, or any such similar plan, program, or policy is not
permitted the Company shall arrange to provide the Executive with benefits
substantially similar to those which he is entitled to receive under such plans,
programs, and policies.  The benefits provided during the period of coverage
under this Section 6.2(a) shall offset any period of coverage in which the
Executive or his dependents may be entitled under the Consolidated Omnibus
Budget Reconciliation Act of 1985; and

     (b)  The Company shall promptly (and in any event within five business days
after a written request by the Executive therefor) either pay or reimburse the
Executive for the reasonable costs and expenses of any executive outplacement
firm selected by the Executive; provided, however, that the Company's liability
hereunder shall be limited to the first $20,000 of such expenses incurred by the
Executive.  The Executive shall provide the Company with reasonable
documentation of the incurrence of such outplacement costs and expenses.

     6.3  Resignation by Executive Not Involving a Change in Control.
          ----------------------------------------------------------

     (a)  If the Executive Resigns for Good Reason during the Term of this
Agreement (other than a resignation covered under Section 6.2 above), then, in
addition to all Salary and Bonus due and payable on or before the Termination
Date and all other payments and benefits the Executive is entitled to receive
under this Agreement, the Executive will receive an amount equal to two times
(2x) an amount equal to Executive's highest annual base salary in effect during
the Term of this Agreement plus the average of the aggregate amounts of bonus
paid or payable to the Executive during the three (3) completed fiscal years
immediately preceding the Termination Date (or such lesser period that the
Executive has been employed by the Company).  This additional payment will be
paid in equal monthly installments over a twenty-three month period following
the Termination Date as if the Executive's employment had continued hereunder
payable in accordance with the normal payroll procedures, as the same may be
modified from time to time.

     (b)  If (i) the Executive resigns his employment during the Term of this
Agreement in a situation other than when the Executive Resigns for Good Reason,
or (ii) the Executive's employment is terminated during the Term of this
Agreement either by the Company or by the Executive (other than with regards to
a situation covered by Section 6.2 above), then, in addition to all Salary and
Bonus due and payable on or before the Termination Date and all other payments
and

                                       13
<PAGE>

benefits the Executive is entitled to receive under this Agreement, the
Executive will receive as additional compensation an amount equal to one times
(1x) the Executive's highest annual base salary in effect during the Term of
this Agreement. This additional compensation payment will be paid in equal
monthly installments over a twenty-three month period following the Termination
Date as if the Executive's employment had continued hereunder payable in
accordance with the normal payroll procedures, as the same may be modified from
time to time.

     6.4  Termination for Cause. If the Executive is terminated for Cause during
          ---------------------
the Term of this Agreement, then, in addition to all Salary and Bonus due and
payable on or before the Termination Date and all other payments and benefits
the Executive is entitled to receive under this Agreement, the Executive will
receive an amount equal to one half (1/2) of one month's Salary for each month
Executive has been employed during the Term of this Agreement, up to a maximum
amount equal to Executive's annual base salary as of the Termination Date, if
and only if the Board of Directors determines in good faith and in its sole
discretion that the for Cause termination does not result from the Executive's
commission of a major criminal offense. This additional compensation payment
will be paid in equal installments over a twenty-three (23) month period
following the Termination Date as if the Executive's employment had continued
hereunder payable in accordance with the normal payroll procedures, as the same
may be modified from time to time. If the reason for the termination for Cause
is that the Executive committed a major criminal offense, the Executive shall
only be entitled to such amount of Salary and Bonus not paid as of the
Termination Date. It is expressly agreed that if there is a termination of the
Executive's employment for Cause under the provisions of Section 5.3, the
Executive will not be entitled to receive any additional amounts payable to the
Executive under Sections 6.2 or 6.3.

     6.5  Termination due to Total Disability. If Executive's employment is
          -----------------------------------
terminated due to Total Disability, then, in addition to all Salary and Bonus
due and payable on or before the Termination Date and all other payments and
benefits the Executive is entitled to receive under this Agreement, the
Executive or his legal guardian, as the case may be, will receive an amount
equal to one-twelfth (1/12/th/) of Executive's Salary times the lesser of (a)
the number of months remaining prior to the expiration of the Term of this
Agreement or (b) twelve (12). This additional compensation payment will be paid
in a lump sum amount within ninety (90) days after the Termination Date. It is
expressly agreed that if there is a termination of the Executive's employment
due to the Total Disability of the Executive under the provisions of Section
5.3, the Executive will not be entitled to receive any additional amounts
payable to the Executive under Sections 6.2 or 6.3.

     6.6  No Additional Payments Upon Death. It is expressly agreed that if the
          ---------------------------------
Executive's employment with the Company is terminated by reason of the death of
the Executive, the Executive will not be entitled to receive any additional
amounts payable to the Executive under Sections 6.2 or 6.3.

     6.7  Protection and Retention. IMCO shall award Executive a grant of shares
          ------------------------
of restricted common stock of IMCO in accordance with the terms of the Award
Agreement evidencing such grant, a copy of which is attached hereto as Exhibit
"A".

                                       14
<PAGE>

     6.8  Mitigation of Damages. In the event the Executive is entitled to any
          ---------------------
additional amounts provided for under this Article VI, the Executive shall not
be required to seek other employment in order to mitigate his damages hereunder,
and no compensation the Executive earns after any such termination shall be
considered to mitigate damages the Executive has incurred or to reduce any
payment the Company is obligated to make to the Executive under this Agreement.

     6.9  Timing of Payment and Deductions. Unless otherwise specifically
          --------------------------------
provided for in this Agreement, any payments payable to the Executive under this
Agreement shall be paid on the Termination Date.  The Company and IMCO shall
have the right with respect to all payments made to the Executive under this
Agreement to withhold therefrom (1) all taxes which may be required to be
deducted or withheld under any provision of applicable law (including but not
limited to state and federal income taxes, Federal Insurance Contributions Act
payments and any other required tax deduction) and (2) all other required non-
tax deductions.

     6.10 Gross Up Payments.
          -----------------

     (a)  In the event that any payment or benefit (within the meaning of
Section 280G of the Code), to the Executive or for his benefit paid or payable
or distributed or distributable (at any time or from time to time) pursuant to
the terms of this Agreement or otherwise in connection with, or arising out of,
his employment with the Company or a change in ownership or effective control of
IMCO or the Company or of a substantial portion of the IMCO Group's consolidated
assets (a "Payment" or "Payments"), would be subject to the excise tax imposed
by Section 4999 of the Code or any interest or penalties are incurred by the
Executive with respect to such excise tax (such excise tax, together with any
such interest and penalties, being hereinafter collectively referred to as the
"Excise Tax"), then the Executive will be entitled to receive an additional
payment or payments, as the case may be (referred to individually or
collectively as a "Gross-Up Payment") in an amount such that after payment by
the Executive of all taxes (including any interest or penalties imposed with
respect to such taxes and the Excise Tax, other than interest and penalties
imposed by reason of the Executive's failure to file timely a tax return or pay
taxes shown due on his return), including any Excise Tax imposed upon the Gross-
Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the
Excise Tax imposed upon the Payments.

     (b)  An initial determination as to whether a Gross-Up Payment is required
pursuant to this Agreement and the amount of such Gross-Up Payment shall be made
at the Company's expense by an accounting firm selected by the Company and
reasonably acceptable to the Executive which is designated as one of the largest
national accounting firms in the United States (the "Accounting Firm").  The
Accounting Firm shall provide its determination (the "Determination"), together
with detailed supporting calculations and documentation to the Company and the
Executive within fifteen (15) days of the Date of Termination if applicable, or
such other time as requested by the Company or by the Executive (provided the
Executive reasonably believes that any of the Payments may be subject to the
Excise Tax) and if the Accounting Firm determines that no Excise Tax is payable
by the Executive with respect to a Payment or Payments, it shall furnish the
Executive with an opinion reasonably acceptable to the Executive that he has
substantial authority not to report any Excise Tax on his federal tax return
with respect to any such Payment or Payments.  Within ten (10) days of the

                                       15
<PAGE>

delivery of the Determination to the Executive, the Executive shall have the
right to dispute the Determination (the "Dispute"). The Gross-Up Payment, if
any, as determined pursuant to this Section 6.10(b) shall be paid by the Company
to the Executive within five days of the receipt of the Accounting Firm's
determination. The existence of the Dispute shall not in any way affect the
Executive's right to receive the Gross-Up Payment in accordance with the
Determination. Upon the final resolution of a Dispute, the Company shall
promptly pay to the Executive any additional amount required by such resolution.
If there is no Dispute, the Determination shall be binding, final and conclusive
upon IMCO, the Company and the Executive.

     (c)  The Executive shall notify the Company in writing of any claim by the
Internal Revenue Service that, if successful, would require the payment
hereunder of a Gross-Up Payment.  Such notification shall be given as soon as
practicable but no later than ten (10) business days after the Executive knows
of such claim and shall inform the Company of the nature of such claim and the
date on which such claim is requested to be paid.  The Executive shall not pay
such claim prior to the expiration of the thirty (30) day period following the
date on which he gives such notice to the Company (or such shorter period ending
on the date that any payment of taxes with respect to such claim is due).  If
the Company does not notify the Executive in writing that it desires to contest
such claim prior to the expiration of such period, the Executive shall be paid
within five (5) business days an amount equal to the Gross-Up Payment required
to be paid as a result of the claim.  If the Company notifies the Executive in
writing prior to the expiration of such period that it desires to contest such
claim, the Executive shall:

          (i)   give the Company any information reasonably requested by the
     Company relating to such claim,

          (ii)  take such action in connection with contesting such claim as the
     Company shall reasonably request in writing from time to time, including,
     without limitation, accepting legal representation with respect to such
     claim by an attorney reasonably selected by the Company,

          (iii) cooperate with the Company in good faith in order to effectively
     contest such claim,

          (iv)  permit the Company to participate in any proceedings relating to
     such claim, provided, however, that the Company shall bear and pay directly
     all costs and expenses (including additional interest and penalties)
     incurred in connection with such contest and shall indemnify and hold the
     Executive harmless, on an after-tax basis, for any Excise Tax or income
     tax, including interest and penalties with respect thereto, imposed as a
     result of such representation and payment of costs and expenses.  Without
     limitation of the foregoing provisions of this Section 6.10(c), the Company
     shall control all proceedings taken in connection with such contest and, at
     its sole option, may pursue or forego any and all administrative appeals,
     proceedings, hearings and conferences with the taxing authority in respect
     of such claim and may, at its sole option, either direct the Executive to
     pay the tax claimed and sue for a

                                       16
<PAGE>

     refund, or contest the claim in any permissible manner, and the Executive
     agrees to prosecute such contest to a determination before any
     administrative tribunal, in a court of initial jurisdiction and in one or
     more appellate courts, as the Company shall determine; provided, however,
     that if the Company directs the Executive to pay such claim and sue for a
     refund, the Company shall advance the amount of such payment to the
     Executive, on an interest-free basis and shall indemnify and hold the
     Executive harmless, on an after-tax basis, from any Excise Tax or income
     tax, including interest or penalties with respect thereto, imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and further provided that any extension of the statute of
     limitations relating to payment of taxes for the taxable year of the
     Executive with respect to which such contested amount is claimed to be due
     is limited solely to such contested amount. Furthermore, the Company's
     control of the contest shall be limited to issues with respect to which a
     Gross-Up Payment would be payable hereunder and the Executive shall be
     entitled to settle or contest, as the case may be, any other issue raised
     by the Internal Revenue Service or any other taxing authority.

     (d)  If, after the receipt by the Executive of an amount advanced by the
Company pursuant to Section 6.10(c), the Executive becomes entitled to receive
any refund with respect to such claim, the Executive shall (subject to the
Company's complying with the requirements of Section 6.10(c)) promptly pay to
the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto).  If, after the receipt by the
Executive of an amount advanced by the Company pursuant to Section 6.10(c), a
determination is made that the Executive shall not be entitled to any refund
with respect to such claim and the Company does not notify the Executive in
writing of its intent to contest such denial of refund prior to the expiration
of thirty (30) days after such determination, then such advance shall be
forgiven and shall not be required to be repaid and the amount of such advance
shall offset, to the extent thereof, the amount of Gross-Up Payment required to
be paid.

                                  ARTICLE VII
                       CERTAIN RESTRICTIONS ON EXECUTIVE

     7.1  General. In consideration of the Company entering into this contract
          -------
for employment, the Company furnishing the Executive, now and throughout the
Term of this Agreement, Confidential Information and specialized training on an
initial and ongoing basis, and the covenants and obligations of the Company
contained in this Agreement, including the covenants and obligations regarding
the additional compensation set forth in Article VI, the Executive hereby
covenants, warrants and agrees to abide by and be subject to the restrictions
and agreements as set forth below in this Article VII.

     7.2  Non-Disclosure of Confidential Information. The Executive hereby
          ------------------------------------------
covenants, warrants and specifically agrees as follows:

                                       17
<PAGE>

     (a)  All of the Confidential Information is a valuable asset and is, will
be, and shall at all times remain the sole and exclusive property of IMCO, the
IMCO Group or, if applicable, the sole and exclusive property of the Company.

     (b)  But for the Executive's employment by the Company, the Executive would
not come into possession of, have knowledge of, or contribute to the
Confidential Information.

     (c)  All Confidential Information disclosed to the Executive or made known
to the Executive (regardless of when or how disclosed or made known) as a result
of his employment by the Company, whether or not with the knowledge and
permission of IMCO, the IMCO Group, or the Company, will be held strictly
confidential and only utilized during the course of his employment at the
Company. The Executive shall hold the said Confidential Information in a
fiduciary capacity for the benefit of IMCO, the IMCO Group, and/or the Company
and will not use the Confidential Information in any way detrimental to IMCO,
the IMCO Group, or the Company.

     (d)  (i)  The Executive will not at any time during or after the Term of
     this Agreement, in any fashion, form or manner, either directly or
     indirectly, publish, reveal, divulge, disclose, disseminate, use (or
     communicate to any individual, firm, partnership, corporation, association,
     enterprise, organization, or other entity, person or business) any
     Confidential Information, or otherwise make it possible for any individual,
     firm, partnership, corporation, association, enterprise, organization, or
     other entity, person or business to have access to any Confidential
     Information, except (1) with the express permission of  IMCO and/or the
     Company, (2) in performance of Executive's duties and obligations to the
     Company and/or IMCO, or (3) as otherwise required to be disclosed by law,
     judicial or administrative process.  If the Executive becomes legally
     compelled, as concluded by the written opinion of counsel, (by oral
     questions, interrogatories, request for information, or documents,
     subpoena, civil investigative demand or similar process) to disclose any
     Confidential Information, the Executive will provide the Company with
     prompt written notice so that the Company and/or IMCO may seek a protective
     order or other appropriate remedy.  It is further agreed that if, in the
     absence of a protective order or the receipt of a waiver hereunder, the
     Executive is, nonetheless, in the opinion of his counsel, compelled to
     disclose any Confidential Information or else stand liable for contempt or
     suffer other censure or penalty, such information which is legally required
     to be disclosed may be disclosed but the Executive will exercise his best
     efforts to obtain reliable assurances that confidential treatment will be
     accorded the Confidential Information so disclosed.

          (ii) Notwithstanding any provision contained in this Agreement to the
     contrary, it is expressly understood, agreed and acknowledged by all
     parties hereto that an integral part of Executive's job description and his
     duties and obligations to the Company and IMCO is furnishing to financial
     analysts, investors, bankers and investment bankers certain information of
     or concerning the Company, IMCO and the IMCO Group, both in the ordinary
     course of business and in special circumstances.  Any such disclosure by
     the Executive of any such information which, as a result of the breadth of
     the definition of "Confidential Information" contained in this Agreement,
     might otherwise violate this

                                       18
<PAGE>

     covenant, and whether disclosed in the ordinary course of business or
     otherwise (including the furnishing or disclosure of any such information
     in connection with any special activities or projects authorized by the
     Board of Directors or the CEO), shall not be deemed to be a breach or
     violation by Executive of this Section 7.2, but rather shall be deemed
     disclosed in connection with and consistent with the Executive's
     performance of his duties and obligations to the Company and/or IMCO.

     (e)  Upon termination of the Executive's employment with the Company for
Cause or Without Cause or upon the request of the Company at any time, the
Executive will promptly return to the Company, and shall retain no copies of,
all Confidential Information prepared by the Executive or coming into the
Executive's possession.

     (f)  IMCO, the IMCO Group and the Company derive a competitive advantage in
the marketplace by maintaining the Confidential Information and knowledge
thereof as secret and unavailable to the Company's, IMCO's and the IMCO Group's
competitors and the general public.

     7.3  Non-Competition. The Executive acknowledges that at the time this
          ---------------
Agreement is entered into, the Company, IMCO and the IMCO Group are furnishing
the Executive, now and throughout the Term of this Agreement, Confidential
Information and specialized training on an initial and ongoing basis, and that
in consideration thereof, in addition to the other consideration and benefits
being provided to Executive as recited herein, the Executive covenants and
specifically agrees with the Company as follows:

     (a)  The Executive, without the prior written consent of the Company, will
not at any time, during the Term of this Agreement and for a period of two (2)
years thereafter (or for such lesser period should the Company so determine),
directly or indirectly:  (i) compete with IMCO, the IMCO Group or the Company in
any manner within the United States, Germany, Wales, or within any other
country, territory or possession where IMCO, the IMCO Group, or the Company
operate (collectively the aforementioned geographic areas are hereinafter
referred to as the "Territory"); (ii) be employed by or serve as an employee,
agent, officer, representative, director of, or as a consultant to any
individual, firm, partnership, corporation, association, enterprise,
organization, or other entity, person or business (other than for IMCO, the IMCO
Group or the Company) that competes with IMCO, the IMCO Group or the Company in
any manner within the Territory; (iii) solicit, attempt to solicit, provide
goods or services to, or attempt to provide goods or services to, any of the
customers or business contacts of IMCO, the IMCO Group or the Company that exist
during the Term of this Agreement; or (iv) acquire or own in any manner any
interest in, or loan any amount to, any individual, firm, partnership,
corporation, association, enterprise, organization, or other entity, person, or
business that competes with IMCO, the IMCO Group or the Company in any manner
within the Territory, except the Executive may own up to two percent (2%) of any
class of issued and outstanding securities of a competitive corporation whose
shares are regularly traded on a national securities exchange or on the over-
the-counter market.

     (b)  The Executive, without the prior written consent of the Company, will
not at any time, during the Term of this Agreement and for a period of two (2)
years thereafter, directly or

                                       19
<PAGE>

indirectly, for himself or for any other individual, firm, partnership,
corporation, association, enterprise, organization, or other entity, person, or
business, solicit, or in any manner attempt to influence or induce any employee
of IMCO, the IMCO Group or the Company to leave the employment of IMCO, the IMCO
Group or the Company as the case may be.

     7.4  Reasonableness, Revival and Reliance.
          ------------------------------------

     (a)  The provisions contained in Sections 7.2 and 7.3 are the result of
specific negotiations between the Executive and the Company, and the Executive
hereby specifically agrees that the provisions are reasonable under the
circumstances.  The Executive further agrees that if, despite the express
agreement of the parties to this Agreement, a court should hold any portion of
Sections 7.2 or 7.3 unenforceable for any reason, the maximum restrictions that
are reasonable under the circumstances, as determined by the court, will be
substituted for the restrictions held unenforceable.  The Executive also
expressly agrees that in the event a court of any jurisdiction within the
Territory (other than a court with jurisdiction in the State of Texas) holds the
covenants and agreements contained in Sections 7.2 and/or 7.3 wholly
unenforceable by reason of the breadth of their scope or otherwise, it is the
intention of the parties that such determination not bar or in any way affect
the Company's right to the relief in the courts of any other jurisdiction within
the Territory, as to breaches of such covenants and agreements in such other
respective jurisdictions, the covenants and Agreements in Sections 7.2 and 7.3
as they relate to each jurisdiction within the Territory being, for this
purpose, severable into diverse and independent covenants and agreements.

     (b)  The Executive's covenants, warranties and agreements set forth herein
shall be revived continuously throughout the Executive's employment by the
Company.

     (c)  The Company is materially relying upon each of the Executive's
representations, covenants, warranties and agreements in entering into this
Agreement and as a condition for paying the additional compensation under
Article VI.

     7.5  Injunctions. Without intending to limit the remedies available to the
          -----------
Company, IMCO, or the IMCO Group, the Executive expressly recognizes and
acknowledges that a breach or violation by the Executive of any of the
covenants, warranties, agreements, or other provisions contained in this Article
VII will cause material irreparable injury to the Company, IMCO and/or the IMCO
Group for which there is not an adequate remedy at law, that it may not be
possible to measure damages for such injuries precisely, and that in the event
of such a breach or violation or the threat thereof, the Company, IMCO, and/or
the IMCO Group will be entitled to obtain a temporary restraining order and/or a
preliminary or permanent injunction restraining the Executive and/or his
affiliates, employees, associates, partners, or agents, either directly or
indirectly, from engaging in activities prohibited by this Article VII and/or
such other relief as may be required to specifically enforce any of the
covenants, warranties, agreements, or other provisions in this Article VII.
Such right to a temporary restraining order and/or injunction will be cumulative
and in addition to whatever other rights or remedies the Company, IMCO and/or
the IMCO Group may possess, at law or in equity.  Nothing contained in this
Agreement will be construed to prevent the Company, IMCO, and/or the IMCO Group
from seeking and recovering for the damages suffered

                                       20
<PAGE>

by any of them or any of their employees as a result of any breach or violation
by the Executive and/or his affiliates, employees, associates, partners, or
agents of the Executive's covenants, warranties, agreements, or other provisions
contained in this Agreement. The Executive by execution of this Agreement agrees
to submit to the jurisdiction of the federal and state courts of the State of
Texas.

                                 ARTICLE VIII
                                INDEMNIFICATION

     During the Term of this Agreement, to the fullest extent permitted by
applicable law in effect on the Effective Date of this Agreement and to such
greater extent as applicable law may hereafter from time to time permit, the
Company shall advance and be responsible for all Expenses (as that term is
defined below) and the Company specifically agrees to and shall defend,
indemnify and hold harmless the Executive and his respective employees,
attorneys, agents, advisors (including, without limitation, attorneys,
accountants, consultants and financial advisors), successors and assigns, from
and against any and all claims, losses, damages, causes of action, demands,
penalties, fines, costs, expenses, suits and other liability of every kind
(including, without limitation all expenses of litigation, court costs,
judgments and interest thereon, and attorney fees) arising out of or resulting
from all acts or decisions made by the Executive while performing his duties and
obligations in accordance with the provisions of this Agreement excepting herein
any claims, losses, damages, causes of action, demands, penalties, fines, costs,
expenses, suits or other liability of every kind that results from the willful
negligence or misconduct of the Executive.  The Company will choose the legal
counsel to defend the Executive and will pay all attorney fees and other
expenses and costs associated with such litigation.  In the event that counsel
of the Company's choice must be disqualified from representing the Company and
the Executive together, then the Executive has the right to select his own
counsel, whose reasonable fees will be paid by the Company.  All agreements and
obligations of the Company contained herein shall continue for so long as the
Executive shall be, or could become, subject to any possible claim or legal
proceeding in respect of which the Executive is granted rights of
indemnification or advancement of Expenses hereunder.  "Expenses" shall include
all reasonable attorneys' fees, retainers, court costs, transcript costs, fees
of experts, witness fees, travel expenses, duplicating costs, printing and
binding costs, telephone charges, postage, delivery service fees, and all other
disbursements or expenses of the types customarily incurred in connection with
prosecuting, defending, preparing to prosecute or defend or investigating claims
or legal proceedings.

                                  ARTICLE IX
                             SUCCESSOR TO COMPANY

     The Company and IMCO agree to require any successor, whether direct or
indirect, whether by purchase, merger, consolidation or otherwise, who succeeds
to all or most of the business or properties and assets of IMCO to execute and
deliver to the Executive a written instrument in form and in substance
reasonably satisfactory to the Executive and his legal counsel pursuant to which
the successor agrees to assume and to timely perform or to cause to be timely
performed all of the Company's and IMCO's covenants, and agreements set forth in
this Agreement (a "Successor

                                       21
<PAGE>

Agreement"). The failure of the Company or IMCO to cause any successor to
execute and deliver a Successor Agreement to the Executive (a) will constitute a
breach of the provisions of this Agreement by the Company and IMCO, and (b) the
Executive, at his sole option, may resign and thereby terminate his employment
by the Company. If the Executive resigns due to the failure of any successor to
execute and deliver a Successor Agreement, the termination of the Executive's
employment will be treated (for all purposes) as a termination where the
Executive Resigns for Good Reason after a Change in Control. As used herein, the
terms "the Company" and "IMCO" shall include any successor to their respective
businesses and/or assets as aforesaid which executes and delivers the Successor
Agreement as contemplated by this Article IX or which otherwise becomes bound by
the terms and provisions hereof by operation of law.

                                   ARTICLE X
                                  ARBITRATION

     Except as noted below, any dispute arising out of this Agreement or the
performance of its provisions shall be settled by binding arbitration in Dallas
County, Texas in accordance with the rules of the American Arbitration
Association then in effect, and judgment may be entered upon the award by any
court having jurisdiction over the matter.  The Company and the Executive
expressly agree that this Article X does not apply to any disputes that touch or
concern the provisions set forth in Section 5.7, Section 11.1, or Article VII
including any action taken by the Company, IMCO and/or the IMCO Group to
specifically enforce the provisions set forth in Article VII.  Disputes related
to matters so excepted shall, in the absence of further agreement between the
parties, be resolved in a court of competent jurisdiction located in Dallas
County, Texas.

                                  ARTICLE XI
                                 MISCELLANEOUS

     11.1  Further Assurances. The Executive agrees and assures the Company
           ------------------

Agreement.

                              IMCO RECYCLING INC.

                               RESTRICTED STOCK
                                AWARD AGREEMENT

     This RESTRICTED STOCK AWARD AGREEMENT (the "Agreement") is entered into
effective as of the Date of Grant by and between Paul V. Dufor (the "Executive")
and IMCO Recycling Inc., a Delaware corporation ("IMCO").

                               WITNESSETH THAT:
                               ---------------

     WHEREAS, IMCO Management Partnership L.P. (the "Company"), IMCO and the
Executive are parties to that certain Employment Agreement dated effective as of
September 1, 2000 (the "Employment Agreement") whereby IMCO agreed, subject to
and in accordance with the terms hereof, that IMCO would grant an award to the
Executive of shares of restricted common stock of IMCO ("Restricted Stock"),
with respect to which the restrictions on ownership and disposition would lapse
upon, among other events and occurrences, the second anniversary of the date of
the occurrence of a "Change in Control" (as that term is defined in the
Employment Agreement);

     NOW, THEREFORE, IT IS AGREED, by and between IMCO and the Executive, as
follows:

     1.   Terms of Award. The following terms used in this Agreement shall have
          --------------
the meanings set forth in this paragraph 1:

     The "Date of Grant" is __________, 2000.

     The number of shares of "Restricted Stock" awarded under this Agreement is
     _______ shares.

     The "Restriction Period" is the period commencing the Date of Grant and
     ending on that day which is the second anniversary date of the date of the
     Change in Control, provided that the Executive has not sooner experienced a
     Termination of Service (as defined below) prior to such date.

     "Termination of Service" shall be deemed to occur on the Termination Date.
<PAGE>

                                                                       EXHIBIT A

Other capitalized terms appearing in this Agreement which are not otherwise
defined in this Agreement shall have the respective terms assigned to them as
set forth in the Employment Agreement.

     2.   Award. The Executive is hereby granted by IMCO the number of shares
          -----
of Restricted Stock set forth in paragraph 1 (the "Award"). Such grant of shares
of Restricted Stock shall only be made from shares of authorized and issued
shares of IMCO common stock held in IMCO's treasury, and not from authorized and
unissued shares. It is hereby understood and agreed that in the event of a
Change in Control, all of the Executive's previously unexercised and outstanding
stock options granted to him by IMCO prior to the Date of Grant (as more
particularly described on Appendix A which is attached hereto and made a part
hereof) shall thereupon terminate and be cancelled and rendered null and void
and of no further effect.

     3.   Dividends and Voting Rights. Until the date of the Change in Control,
          ---------------------------
the Executive shall not be entitled to receive any dividends with respect to
shares of Restricted Stock that become payable during the Restriction Period and
no dividends shall accrue with respect thereto; provided, however, that
dividends shall be payable to or for the benefit of the Executive with respect
to record dates for such dividends occurring after the date of the Change in
Control and prior to the date (if any) on which the Executive has forfeited the
Restricted Stock.  The Executive shall be entitled to vote the shares of
Restricted Stock during the Restriction Period to the same extent as would have
been applicable to the Executive if the Executive was then vested in the shares;
provided, however, that the Executive shall not be entitled to vote the shares
with respect to record dates occurring prior to the Date of Grant, or with
respect to record dates occurring on or after the date (if any) on which the
Executive has forfeited the Restricted Stock.

     4.   Deposit of Shares of Restricted Stock. Each certificate issued in
          -------------------------------------
respect of shares of Restricted Stock granted under this Agreement shall be
registered in the name of the Executive but shall remain in the custody of IMCO
or the Company until all restrictions on such Restricted Stock have lapsed and
the Restriction Period for such shares of Restricted Stock has expired.

     5.   Transfer and Forfeiture of Shares. Subject to the terms hereof, shares
          ---------------------------------
of Restricted Stock may not be sold, assigned, transferred, pledged or otherwise
encumbered until the expiration of the Restriction Period. Except as otherwise
expressly provided in paragraph 6, if the Termination of Service occurs

<PAGE>

                                                                       EXHIBIT A

prior to the end of the Restriction Period, the Executive shall forfeit the
shares of Restricted Stock effective as of the Termination of Service.

     6.   Vesting. If there has not been a Termination of Service during the
          -------
Restriction Period, then upon the expiration of the Restriction Period, the
Executive shall become 100% vested in the shares of Restricted Stock awarded
hereunder, and shall own those shares free of all restrictions otherwise imposed
by this Agreement.  In addition, the Executive shall also become fully vested in
all of the shares of Restricted Stock awarded hereunder prior to the end of the
Restriction Period, and become owner of such shares free of all restrictions
otherwise imposed by this Agreement, as follows:

          (a)  The Executive shall become fully vested in all of the shares of
     Restricted Stock awarded hereunder as of the date of the Executive's
     Termination of Service, if such Termination of Service occurs on or after
     that date which is 90 days prior to the date of the Change in Control by
     reason of the Executive's death, Total Disability or retirement in
     accordance with Company policies concerning executive retirement as in
     effect on September 1, 2000; or

          (b)  The Executive shall become fully vested in all of the shares of
     Restricted Stock awarded hereunder as of the date of the Termination of
     Service, if the Executive is Terminated Without Cause or the Executive
     Resigns for Good Reason at any time on or after that date which is 90 days
     prior to the Change in Control; or

          (c)  The Executive shall become fully vested in all of the shares of
     Restricted Stock awarded hereunder upon the occurrence of a Change in
     Control and the obligations of IMCO under this Agreement with respect to
     the Award are not fully assumed or replaced by equivalent substitute
     award(s), as more fully described in paragraph 7 below; or

          (d)  If in connection with a Change of Control the obligations of IMCO
     under this Agreement with respect to the Award are assumed or equivalent
     substitute award(s) are granted in lieu thereof, but a subsequent Change in
     Control occurs before the expiration of the Restriction Period, then
     effective upon such subsequent Change in Control, the Executive shall
     become fully vested in all of the shares of Restricted Stock awarded
     hereunder, as more fully described in paragraph 7 below.

                                                                       EXHIBIT A

     7.   Assumption Following Change in Control. If there occurs a Change in
          ---------------------------------------
Control under which the obligations of IMCO with respect to the outstanding
Award under this Agreement are not assumed, or such Award is not replaced by
equivalent substitute award(s) by IMCO or IMCO's Successor (as defined below),
then the Restriction Period applicable to all shares of Restricted Stock granted
under this Agreement shall thereupon automatically terminate, and IMCO or the
Company shall provide reasonable prior written notice to the Executive of the
date such Restriction Period will so expire.

     In the event of any Change in Control prior to the expiration of the
Restriction Period, but subsequent to the date of a previous Change in Control
with respect to which the obligations of IMCO regarding the outstanding Award
under this Agreement were fully assumed by IMCO or IMCO's Successor or such
Award was replaced by equivalent substitute award(s), then, notwithstanding any
provision to the contrary contained in this Agreement, the Restriction Period
applicable to all shares of Restricted Stock granted under this Agreement shall
thereupon automatically terminate, and the Company and IMCO or IMCO's Successor
shall provide reasonable prior written notice to the Executive of the date such
Restriction Period will so expire.

     As used herein, the term "IMCO" shall mean IMCO as hereinbefore defined,
and "IMCO's Successor" shall mean any successor to IMCO's business or assets as
aforesaid which executes and delivers an agreement to assume IMCO's obligations
under this Agreement or which otherwise becomes bound by all of the terms and
provisions hereof by operation of law.

     8.   Heirs and Successors. This Agreement shall be binding upon, and inure
          --------------------
to the benefit of, IMCO and its successors and assigns, and upon any person
acquiring, whether by merger, consolidation, purchase of assets or otherwise,
all or substantially all of IMCO's assets and business.    Any benefits
distributable to the Executive under this Agreement that are not distributed at
the time of the Executive's death shall be distributed at the time and in the
form determined in accordance with the provisions of this Agreement and the
Employment Agreement to the beneficiary designated by the Executive in writing
filed with the Company or IMCO in such form and at such time as the Company or
IMCO shall require.  If a deceased Executive has failed to designate a
beneficiary, or if the designated beneficiary of the deceased Executive dies
before the Executive or before complete distribution of benefits due under this
Agreement, the amounts to be distributed under this Agreement shall be

                                       4

                                                                       EXHIBIT A

distributed to the legal representative or representatives of the estate of the
last to die of the Executive and the beneficiary.

     9.   Administration. The authority to manage and control the administration
          --------------
of this Agreement shall be vested in the Compensation Committee of the Board of
Directors.

     10.  Amendment. This Agreement may be amended only by written agreement of
          ---------
the Executive and IMCO, without the consent of any other person.

     11.  Adjustments. Except as otherwise expressly provided in this Agreement,
          -----------
the issuance by IMCO (or IMCO's Successor) of shares of its capital stock of any
class, or securities convertible into shares of capital stock of any class,
either in connection with direct sale or upon the exercise of rights, options,
or warrants to subscribe therefor, or upon conversion of shares or obligations
of IMCO or IMCO's Successor convertible into such shares or other securities,
shall not affect, and no adjustment by reason thereof shall be made with respect
to, the number of outstanding shares of Restricted Stock.

     12.  Recapitalization, Merger and Consolidation; Change in Control.
          -------------------------------------------------------------

          (a)  The existence of this Agreement and the Award granted hereunder
     shall not affect in any way the right or power of IMCO or its stockholders
     to make or authorize any or all adjustments, recapitalizations,
     reorganizations, or other changes in IMCO's capital structure and its
     business, or any merger or consolidation of IMCO, or any issue of bonds,
     debentures, preferred or preference stocks ranking prior to or otherwise
     affecting the Common Stock or the rights thereof (or any rights, options,
     or warrants to purchase same), or the dissolution or liquidation of IMCO
     or, or any sale or transfer of all or any part of its assets or business,
     or any other corporate act or proceeding, whether of a similar character or
     otherwise.

          (b)  Subject to any required action by the stockholders (and except as
     otherwise provided in sub-paragraph (c) below), if IMCO shall be the
                           -----------------
     surviving or resulting corporation in any merger, consolidation or share
     exchange, the Award granted hereunder shall pertain to and apply to the
     securities or rights (including cash, property, or assets) to which a
     holder of the number of shares of Common Stock subject to the Award would
     have been entitled.

                                                                       EXHIBIT A

          (c)  In the event of any merger, consolidation or share exchange
     pursuant to which IMCO is not the surviving or resulting corporation, (or
     IMCO is the surviving entity but the Common Stock of IMCO is exchanged for
     cash, property, securities or other consideration of or from any other
     entity) there shall be substituted for each share of Common Stock subject
     to this Award, (i) that number of shares of each class of stock or other
     securities or that amount of cash, property, or assets of the surviving,
     resulting or consolidated entity which were distributed or distributable to
     the stockholders of IMCO in respect of each share of Common Stock held by
     them, or (ii) such number of shares of stock, or other securities, or such
     amount of cash, property or assets (or any combination thereof) as
     proportionate in value as reasonably practicable to the consideration
     distributed or distributable to the stockholders of IMCO with respect to
     each share of Common Stock held by them.

          (d)  In case IMCO shall, at any time while this Award is outstanding
     and the Restriction Period remains unexpired, (i) sell all or substantially
     all of its property, or (ii) dissolve, liquidate, or wind up its affairs,
     then the Executive shall be thereafter entitled to receive, in lieu of each
     share of Common Stock which the Executive would have been entitled to
     receive under the Award, the same kind and amount of any securities or
     assets as may be issuable, distributable, or payable upon any such sale,
     dissolution, liquidation, or winding up with respect to each share of
     Common Stock of IMCO.

     13.  Investment Intent. IMCO may require that there be presented to and
          -----------------
filed with it such evidence as it may deem necessary to establish that the
shares of Common Stock to be transferred to the Executive are being acquired for
investment purposes only and not with a view to their resale or distribution.

     14.  No Right to Continued Employment. This Agreement shall not confer upon
          --------------------------------
the Executive any right with respect to continuance of employment by the Company
or any other company in the IMCO Group (as that term is defined in the
Employment Agreement).

     15.  Compliance With Other Laws and Regulations. The grant of the Award and
          ------------------------------------------
the obligation of IMCO to deliver shares of Common Stock hereunder, shall be
subject to all applicable federal and state laws, rules and regulations and to
such approvals by any government or regulatory agency as may be required. In

                                                                       EXHIBIT A

the event it is determined that any such grant, issuance or delivery for any
reason violates any law, rule or regulation, then the Award shall thereupon
automatically convert to a phantom restricted stock award or other similar
equivalent award, having a value substantially equivalent to the value of the
Award, and payable in cash instead of Common Stock. Such award will be
exercisable at any time the Executive may elect on or after the date such award
becomes fully vested in accordance with the vesting terms applicable to the
Award granted hereunder (but at any rate not more than three years after full
vesting occurs.)

     16.  Tax Requirements. IMCO or the Company shall have the right to deduct
          ----------------
any Federal, state, or local taxes required by law to be withheld with respect
to the Award hereunder.  The Executive receiving shares of Common Stock issued
under this Agreement shall be required to pay IMCO or the Company the amount of
any taxes which IMCO or the Company is required to withhold with respect to such
shares of Common Stock.

     17.  Legend. Each certificate representing shares of Restricted Stock
          ------
issued to the Executive shall bear the following legend, or a similar legend
deemed by IMCO to constitute an appropriate notice of the provisions hereof (any
such certificate not having such legend shall be surrendered by the Executive
upon demand by IMCO and so endorsed):

          On the face of the certificate:

          "Transfer of this stock is restricted in accordance with
          conditions printed on the reverse of this certificate."

          On the reverse:

          "The shares of stock evidenced by this certificate are
          subject to and transferable only in accordance with the
          terms of the IMCO Recycling Inc. Restricted Stock Award
          Agreement dated October 12, 2000, a copy of which is on file
          at the principal executive offices of IMCO Recycling Inc. in
          Irving, Texas. No transfer or pledge of the shares evidenced
          hereby may be made except in accordance with and subject to
          the provisions of said Agreement. By acceptance of this
          certificate, any holder, transferee or pledgee hereof agrees
          to be bound by all of the provisions of said Agreement."

     The following legend shall be inserted on each certificate evidencing
Common Stock issued hereunder if the shares were not issued in a transaction
registered under the applicable federal and state securities laws:

          "Shares of stock represented by this certificate have been
          acquired by the holder for investment purposes only and not
          for resale, transfer or distribution, have been issued
          pursuant to exemptions from the registration requirements of
          applicable state and federal securities laws, and may not be
          offered for sale, sold or transferred other than pursuant to
          effective registration under such laws, or in transactions
          otherwise in compliance with such laws, and upon evidence
          satisfactory to IMCO Recycling Inc. of compliance with such
          laws, as to which IMCO Recycling Inc. may rely upon an
          opinion of counsel satisfactory to IMCO Recycling Inc."

     IN WITNESS WHEREOF, the Executive has executed this Agreement, and IMCO has
caused this Agreement to be executed in its name and on its behalf, all
effective as of the Date of Grant.
