Item 2. Disposition of Assets
- -----------------------------

On October 13, 1998, pursuant to a Stock Purchase and Sale Agreement, dated as
of April 25, 1998, by and among Cyprus Amax Minerals Company ("Cyprus Amax"),
Cyprus Foote Mineral Company ("Foote"), Cyprus Specialty Metals Company ("Cyprus
Specialty") and Foote Acquisition Corporation ("Buyer"), Cyprus Amax completed
the sale of its Foote lithium subsidiary to an affiliate of Chemetall GmbH, a
specialty chemicals unit of Metallgesellschaft AG. Prior to the consummation of
the stock purchase transaction, Buyer was a significant customer of Foote. The
terms of the transaction were established through arm's length negotiation.

Cyprus Amax received $305 million in cash in the transaction and expects to
report a pre-tax gain of approximately $150 million from the sale.  This should
result in an after-tax gain of slightly over $100 million in the fourth quarter.
However, as a result of the sale of assets earlier in the year, only a nominal
amount of federal income taxes are expected to be paid.  Proceeds from the sale
are expected to be used for general corporate purposes, including debt
reduction, the share buyback program and to strengthen Cyprus Amax's financial
position and core mining businesses.

          (l)  notes, bonds, indentures or guarantees that involve a potential
liability of either the Company or the Chilean Partnership of more than $1
million; or

          (m)  agreements, contracts or commitments relating to capital
expenditures and involving future payments that, together with future payments
under all other agreements, contracts or commitments relating to the same
capital project, exceed $1 million.

          Except as otherwise set forth in Schedule 3.2.13, to Cyprus Amax's
Knowledge, the Material Contracts are in full force and effect, are valid,
binding and enforceable against the parties thereto, except to the extent that
the enforcement of rights and remedies in respect thereof may be subject to
bankruptcy, reorganization, insolvency, moratorium or similar laws affecting
creditor's rights generally, and none are terminable as a result of the
transactions contemplated by this Agreement or the Related Agreements.  No
default by the Company or, to Cyprus Amax's Knowledge, by the other contracting
parties has occurred thereunder which could reasonably be expected to have a
Material Adverse Effect.  To Cyprus Amax's Knowledge, no event, occurrence or
condition exists which, with the lapse of time, or the giving of notice or both,
would become a default by the Company or by the other contracting parties
thereunder which could reasonably be expected to have a Material Adverse Effect.

          No Material Contract is terminable or subject, by its terms, to
material modification as a result of the transactions contemplated by this
Agreement or the Related Agreements except as specified in the next succeeding
sentence.  The Material Contracts set forth on Schedule 3.2.13 to which a
consent or approval to the transactions provided for in this Agreement is
required are designated with an asterisk and are referred to herein as "Material
Restricted Contracts".

the Chilean Partnership is a party to any collective bargaining agreements with

          (c)  No labor strike or material organized work stoppage against the
Company or the Chilean Partnership is pending or, to Cyprus Amax's Knowledge,
threatened.  Except as set forth on Schedule 3.2.14, the Company and the Chilean

threatened with any material action, suit, proceeding, claim or charge with
respect to any (i) labor dispute, grievance, or litigation relating to labor
matters involving any of its employees for purposes of bargaining or otherwise
negotiating with the Company, (ii) charges of unfair labor practices or (iii)
employment discrimination (whether on the basis of sex, age, race, national
origin, handicap or veteran status) or (iv) wrongful discharge or termination of
employment, which in any of the foregoing cases, individually or in the
aggregate could reasonably be expected to result in a Material Adverse Effect.
To Cyprus Amax's Knowledge, no efforts are currently being made and no petition
is being circulated or filed to organize any employees of the Company or the
Chilean Partnership for purposes of bargaining or otherwise negotiating with the
Company or the Chilean Partnership to designate or certify any labor
organization or other Person or entity as bargaining agent or to hold any

          (d)  The Company (i) is in compliance with all laws, rules and

practices, terms and conditions of employment, wages and hours, except for those
instances which, in the aggregate, could not reasonably be expected to result in
a Material Adverse Effect; (ii) has withheld all material amounts required by
Law from the wages, salaries and other payments to employees; (iii) is not
liable for any material arrears of wages or any material penalty for failure to
comply with any of the foregoing; and (iv) except in the ordinary course of
business, is not liable for any material payment to any trust or other fund or
to any Governmental Authority, with respect to unemployment compensation
benefits, social security or other legally mandated benefits for employees;

matters addressed in Section 3.2.20.

          (e)  Except as disclosed on Schedule 3.2.14, to Cyprus Amax's
Knowledge, there are no pending investigations of the Company by the Equal
Employment Opportunity Commission, any state civil rights commission, or any
other Governmental Authority responsible for investigation of worker complaints
for discrimination, which could reasonably be expected to have a Material
Adverse Effect.  Further, to Cyprus Amax's Knowledge, there are no pending
investigations of the Company by the U.S. Department of Labor, any state
department of labor, the Mine Safety and Health Administration or the
Occupational Safety and Health Administration, which could reasonably be
expected to have a Material Adverse Effect.

Knowledge of Cyprus Amax, any Governmental investigations pending or any
actions, suits or proceedings threatened, against the Company or the Chilean
Partnership which could reasonably be expected to result in a Material Adverse
Effect, or which seek to delay or question the validity of this Agreement or the
Related Agreements or of any action taken or to be taken by the Company,
Specialty or Cyprus Amax pursuant hereto or thereto or in connection herewith or
therewith or the transactions contemplated hereby or thereby, and (ii) there are
no outstanding judicial or administrative orders or decrees to which the Company
or the Chilean Partnership is subject, which could reasonably be expected to
result in a Material Adverse Effect, other than those applicable generally to
the industry in which the Company operates.

          3.2.16  Absence of Changes or Events.  Except as set forth in Schedule
                  ----------------------------

          3.2.17  Compliance with Laws.  To Cyprus Amax's Knowledge, except as
                  --------------------                                        
provided on Schedule 3.2.17 hereto, the Company (including the Chilean
Partnership) is in compliance with all Laws, and is not in default or violation
of any, Laws, of all Governmental Authorities applicable to its business,
operations and assets, the failure to comply with which could reasonably be
expected to have a Material Adverse Effect.  To Cyprus Amax's Knowledge, neither
Cyprus Amax, the Company, nor the Chilean Partnership either on its own behalf
or on behalf of any of its respective officers, agents, consultants, or
employees, has, with respect to the business of the Company (including the

          3.2.18  Licenses, Permits, Approvals.  The Company  (including the
                  ----------------------------                              
Chilean Partnership) possesses all licenses, permits, grants and governmental
approvals and authorizations which are required in order to operate its
businesses as currently operated, other than those which, the failure to possess
could not reasonably be expected to have a Material Adverse Effect.  To Cyprus
Amax's Knowledge, each of the Company and the Chilean Partnership has duly filed
all reports and returns required to be filed by it with any Governmental
Authority and obtained all Governmental permits and licenses and other
Governmental consents (including the Chilean Nuclear Energy Commission) which
are required in connection with the businesses and operations of each of the
Company and the Chilean Partnership, the failure of which could reasonably be
expected to have a Material Adverse Effect.  To the Knowledge of Cyprus Amax,
all of such permits, licenses and consents are in full force and effect, and to
the Knowledge of Cyprus Amax, no proceedings for the suspension or cancellation
of any of them are pending or threatened, which could reasonably be expected to
have a Material Adverse Effect.

          3.2.19  Insurance.  To Cyprus Amax's Knowledge, Schedule 3.2.19 lists
                  ---------                                                    
all policies of fire, liability, or other material forms of third party
insurance issued solely in the name of the Company or the Chilean Partnership
and, to the Knowledge of Cyprus Amax, no premiums are past due.  To Cyprus
Amax's Knowledge, Schedule 3.2.19 also lists all bonds, including reclamation
bonds, currently in force with respect to the Company or its operations issued
solely in the name of the Company.

          3.2.20  Employee Benefit Plans.
                  ---------------------- 

          (a)  Schedule 3.2.20 lists all deferred compensation, pension, profit
sharing and retirement plans, and all life or other welfare or employee benefit
insurance, incentive compensation, stock option, severance or termination pay,
hospitalization or other medical plan, arrangement or agreement, bonus and other
employee benefit, welfare or fringe benefit plans, arrangements or practices,
written or otherwise, or any other "employee benefit plan," as defined in
Section 3(3) of ERISA, whether formal or informal, in effect as of the Closing
with respect to which contributions, premiums or other payments are made or
required by the Company with respect to any current or former employees (the
"Plans").  Schedule 3.2.20 identifies each Plan to be in effect at the Closing
as either (i) a Plan maintained by the Company ("Company Plan") or (ii) a Plan
maintained by Cyprus Amax, but under which the Company is a participating
employer ("Cyprus Amax Plan").  None of the Plans are, and the Company has never
contributed or had an obligation to contribute to a "multiemployer plan," as
defined in Section 3(37) of ERISA (a "Multiemployer Plan") or a "multiple
employer plan," as defined in ERISA or the Code.  Except as provided in Section
4.3.6, neither Cyprus Amax nor the Company has any agreement or commitment to
create any additional Plan or modify or change any Plan.  Subject to any
applicable collective bargaining agreement, each of the Company Plans
(including, without limitation, any Company Plan providing retiree medical
benefits) can be 

                                      -21-

<PAGE>
 
amended, modified or terminated by Cyprus Amax or the Company within a period of
thirty (30) days without payment of any additional compensation or amount, or
the additional vesting or acceleration of any such benefits, except to the
extent that such vesting is required under the Code upon the complete or partial
termination of any Company Plan intended to be "qualified" within the meaning of
Section 401(a) of the Code. To the Knowledge of Cyprus Amax, no statement of any
kind, written or oral, has been made by Cyprus Amax, the Company, or any of
their officers, directors, employees, or agents, with respect to any Company
Plan that was inconsistent with the ability of Cyprus Amax or the Company to so
amend, modify or terminate such Company Plan. True and complete copies of the
Plans have been made available to Buyer.

          (b)  With respect to the Plans, the Company is in compliance, in all
material respects, with the Plan terms, and, where applicable, the Code, ERISA
and any other applicable Laws, and has performed and complied in all material
respects with all of its obligations under and with respect to the Plans and any
applicable collective bargaining agreement.  Each Plan has, at all times, in
form, operation and administration, complied in all material respects with its
terms, and where applicable, the Code, ERISA, and any other applicable Laws.

          (c)  Each Company Plan, which is intended to be "qualified" within the
meaning of Section 401(a) of the Code, has received a favorable determination
letter from the Internal Revenue Service and, to the Knowledge of Cyprus Amax
and the Company, no event has occurred and no condition exists which could
reasonably be expected to result in the revocation of any such determination.
Except as provided on Schedule 3.2.20 hereto and except as provided in Section
4.3.6, since the date of the Company Plans and documents related thereto made
available to Buyer, there has not been any change in the terms or operations of
the Company Plan which could reasonably be expected to affect or alter the tax
status or materially affect the cost of maintaining any Company Plan, and none
of the Company Plans has been or will be amended prior to the Closing Date,
without Buyer's consent.

          (d)  All contributions which are due from the Company under any Plan
have been paid to each such Plan or accrued in accordance with the past practice
of Cyprus Amax and the Company.  All premiums or other payments that are due
before the Closing Date have been paid with respect to each Plan that is an
employee welfare benefit plan (as defined in Section 3(1) of ERISA).

          (e)  Neither the Company, Cyprus Amax, or any of its subsidiaries nor,
to the Knowledge of Cyprus Amax or the Company, any other "disqualified Person"
or "party in interest" as defined in Section 4975(e)(2) of the Code and Section
3(14) of ERISA, respectively, have engaged in any transaction in connection with
any Company Plan that could reasonably be expected to result in the 

                                      -22-

<PAGE>
 
imposition of a material penalty pursuant to Section 502(i) of ERISA, damages
pursuant to Section 409 of ERISA, or a tax pursuant to Section 4975(a) of the
Code or any other material penalty, damage, tax or other sanction or liability
under the Code, ERISA, or any other applicable Laws.

          (f)   Except as set forth on Schedule 3.2.20, no action, suit,
proceeding or investigation with respect to the administration or investment of
assets of any Company Plan (other than routine claims for benefits) is pending
or, to Cyprus Amax's Knowledge, threatened that could reasonably be expected to
have a Material Adverse Effect and no filing, application or other matter is
pending with the Internal Revenue Service, the Pension Benefit Guaranty
Corporation (the "PBGC"), the United States Department of Labor or any other
governmental body.

          (g)   Each Company Plan that is a "group health plan" (as defined in
Section 607(l) of ERISA and Section 5000(b)1 of the  Code), has complied in all
material respects with the requirements of Part 6 of Subtitle B of Title I of
ERISA and of Section 4980B of the Code, except where non-compliance could not
reasonably be expected to have a Material Adverse Effect.  The calculation of
the projected liability of the Company for post-retirement benefits other than
pensions that was provided to Buyer was made in accordance with Financial
Accounting Statement 106 of the Financial Accounting Standards Board, and, as of
March 31, 1998, the total "accumulated postretirement benefit obligation" for
such benefits for current employees does not exceed $1.7 million.

          (h)   With respect to each Plan subject to Section 412 of the Code,
there has occurred no failure to meet the minimum funding standards of Section
412 of the Code (whether or not waived in accordance with Section 412(d) of the
Code) or failure to make by its due date a required installment under Section
412(m) of the Code.  With respect to each Plan which is an "employee pension
benefit plan," as defined in Section 3(2) of ERISA (a "Pension Plan"):  (i) all
required premium payments to the PBGC have been paid when due, (ii) no
reportable event, as described in Section 4043 of ERISA (for which reporting has
not been waived), has occurred with respect to any Pension Plan, (iii) no excise
taxes are payable under the Code, (iv) no amendment with respect to which
security is required under Section 307 of ERISA or Section 401(a)(29) of the
Code has been made or is reasonably expected to be made, and (iv) there has been
no event which could subject the Company to liability under Section 4064 or 4069
of ERISA.

          (i)  The Company has not incurred any liability or taken any action
and, to the Knowledge of Cyprus Amax, no action or event has occurred, that
could cause the Company to incur any liability (i) under Section 412 of the Code
or Title IV of ERISA with respect to any "single-employer plan" (as defined in
Section 4001(a)(15) of ERISA, (ii) on account of a partial or complete
withdrawal (as defined in Sections 4203 and 4205 of ERISA, respectively) with
respect to any 

                                      -23-

<PAGE>
 
Multiemployer Plan, or (iii) on account of unpaid contributions to any
Multiemployer Plan.

          (j)  Except as provided in Section 4.3.6 or on the Schedules hereto,
neither the execution and delivery of this Agreement nor the consummation of any
or all of the contemplated transactions will:  (i) entitle any current or former
employee of the Company to severance pay, unemployment compensation or any
similar payment from the Company, (ii) accelerate the time of payment or vesting
or increase the amount of any compensation due to any such employee or former
employee from the Company, or (iii) directly or indirectly result in any payment
made or to be made to or on behalf of any Person to constitute a "parachute
payment" within the meaning of Section 280G of the Code.

          (k)  Notwithstanding anything contained herein to the contrary, the
representations and warranties contained in this Section 3.2.20((a)-(j)), are
made only as to the Company, excluding the Chilean Partnership.  To the
Knowledge of Cyprus Amax, all employee benefit plans of the Chilean Partnership
comply in all material respects with applicable Laws, except where noncompliance
could not reasonably be expected to have a Material Adverse Effect.

          3.2.21  Bank Relationships.  Schedule 3.2.21 sets forth:  (i) the
                  ------------------                                       
names of all banks that are depositories of funds of the Company and/or the
Chilean Partnership; (ii) the names of all Persons authorized to draw or sign
checks or drafts upon such accounts; (iii) the names and locations of any
institutions in which the Company and/or the Chilean Partnership has safe
deposit boxes; (iv) the names of the Persons having access to such safe deposit
boxes; and (v) the names of all officers of the Company and/or the Chilean
Partnership who, according to the records of banks or other lending
institutions, are authorized and empowered to make any borrowings on behalf of
the Company and/or the Chilean Partnership.

          3.2.22  Reserve Information.
                  ------------------- 

          (a) Certain estimates of the proven and probable Lithium reserves of
the Company (including the Chilean Partnership) are attached hereto as Schedule
3.2.22 (the "Estimates").  To Cyprus Amax's Knowledge, the Estimates were
prepared, in all material respects: (i) by Persons qualified to make such
estimates, and (ii) using reasonable geologic, hydrologic and engineering
methods, practices and assumptions.  Since the date of the Estimates, to Cyprus
Amax's Knowledge, nothing has come to Cyprus Amax's attention which would cause
it to believe that the Estimates were overstated, in any material respect, and
to Cyprus Amax's Knowledge there has been no material change in the reserves set
forth in the Estimates other than changes arising from mining, acquisitions and
dispositions since the date thereof in the ordinary course of business.

                                      -24-

          (b) The lithium concession at the Salar de Atacama in favor of the
Chilean Partnership (which concession to the Knowledge of Cyprus Amax, is in
full force and effect in accordance with its terms) provides that, absent
dissolution or bankruptcy, it will be in full force and effect until the
production and sale by the Chilean Partnership of lithium or lithium products
containing 200,000 metric tons of metallic lithium equivalent free of any annual
volume restrictions beginning in July 2001, of which concession less than 25,000
metric tons of metallic lithium will be utilized prior to the Closing Date.
This Agreement, the Related Agreements and the transactions contemplated hereby
and thereby do not constitute a dissolution or bankruptcy of the Chilean
Partnership.

requirement to disclose any such confidential information, so that Cyprus Amax
may seek appropriate legal relief.  In the event that the contemplated
transactions under this Agreement are not consummated for any reason, Buyer will
promptly, upon the request of Cyprus Amax or the Company, deliver to Cyprus Amax
a certification that all such confidential information furnished to Buyer or
their representatives by Cyprus Amax, the Company or their representatives has
been destroyed, or returned to Cyprus Amax.  This provision and all other
confidentiality obligations of Buyer and its Affiliates pertaining to
information with respect to the Company, shall be of no further force or effect
after the Closing.

          4.1.2  No Solicitation by Buyer.  In addition to, and not in
                 ------------------------                             
limitation of any other agreements pertaining to the Company's, Specialty's or
Cyprus Amax's employees previously entered into by Buyer, commencing on the date
of this Agreement and ending on the termination or consummation of this
Agreement, Buyer on behalf of itself and its Affiliates, agrees not to hire or
attempt to hire any employees of Cyprus Amax, Specialty or the Company to the
extent prohibited by the Confidentiality Agreement dated December 20, 1997,
other than (i) those persons responding to advertisements of general
solicitation, and (ii) those persons who have been terminated by Cyprus Amax,
Specialty or the Company.  Nothing contained herein shall prevent Buyer from
conducting interviews of employees of the Company (including the Chilean
Partnership) prior to Closing with the consent of Cyprus Amax not to be
unreasonably withheld.

SECTION 4.2  COVENANTS AND AGREEMENTS OF CYPRUS AMAX AND SPECIALTY
             -----------------------------------------------------

          4.2.1  Access to Information.  Cyprus Amax shall cause the Company to
                 ---------------------                                         
afford Buyer and its employees and representatives access, during normal
business hours and upon reasonable notice, to all of the books, records,
agreements and properties of the Company, and shall furnish to Buyer and its
employees and representatives such information regarding the Company as Buyer
may reasonably request; provided, however, that any such investigation shall be
                        --------  -------                                      
conducted in such a manner as not to interfere unreasonably with the operation
of the business of the Company or of Cyprus Amax.

          4.2.2  Ordinary Course of Business.  Except as otherwise contemplated
                 ---------------------------                                   
by this Agreement or as set forth on Schedule 4.2.2 (including the Chilean
Restructuring, and subject to such changes in the manner of implementing such
restructuring described on Schedule 4.2.2 which are not adverse to Buyer),
Cyprus Amax shall not permit the Company to enter into any material transaction
outside of its ordinary course of business without the express written consent
of Buyer, including, without limitation, (i) the sale, issuance or transfer of
any capital stock or other equity interest or any action in connection
therewith, (ii) the borrowing from third parties of money, (iii) the merger or
consolidation with any entity, or (iv) the transfer of assets other than in the
ordinary course of business consistent with past practice.  Notwithstanding
anything contained herein to the contrary, prior to Closing, the Company may
transfer the Naturita and Newmire properties to an Affiliate of Cyprus Amax.
Cyprus Amax shall cause the Company to use all reasonable efforts consistent
with past practices to preserve and maintain substantially intact its business,
operations, assets and present relationships with its customers, suppliers and
employees.  Except to the extent required by any applicable Laws, as
contemplated by this Agreement or in the ordinary course of business consistent
with past practice, Cyprus Amax shall not permit the Company to increase the
rate of compensation or other remuneration of any employee, enter into any
agreement or commitment to create any additional Plan, contract, agreement or
arrangement concerning any current or former employee, or otherwise amend,
modify or terminate any existing Plan.

          4.2.3  Exclusivity.  Prior to the Closing or termination of this
                 -----------                                              
Agreement in accordance with Article X, Cyprus Amax shall not enter into and
shall cause the Company and Cyprus Amax's other Affiliates not to solicit,
encourage, enter into or continue negotiations or substantive discussions with,
or provide confidential information to, parties other than Buyer with respect to
the sale or transfer of the Company, the Chilean Partnership, the Company Shares
or any other form of business combination transaction involving the Company, the
Company Shares or the Company's or the Chilean Partnership's assets.

          4.2.4  Intercompany Accounts; Cash Accounts.
                 ------------------------------------ 

          (a)  All intercompany accounts, including any intercompany promissory
notes, providing for the payment of any amounts between the Company (including
the Chilean Partnership) on the one hand, and Cyprus Amax and its Affiliates
(other than the Company and the Chilean Partnership) on the other hand, shall be
settled via dividend to the extent of retained earnings and then a return of
capital if the amount is a receivable on the Company books, or as an increase of
paid-in capital if the amount is a payable on the Company books as of the
Closing Date, with no cash or other payments being made.  Nothing in this
Section 4.2.4(a) shall limit the provisions of Section 2.2 hereof.

          (b)  Except as otherwise contemplated by this Agreement, all
agreements between the Company (including the Chilean Partnership) on one hand,
and Cyprus Amax and its Affiliates (other than the Company or the Chilean
Partnership) on the other hand, each of which are set forth on Schedule
4.2.4(b), shall be terminated and of no further force and effect, as of the
Closing Date.

          (c)  At or before the Closing, all cash and cash equivalents of the
Company (including the Chilean Partnership) will be transferred to Cyprus Amax
or its Affiliates for no consideration.  Nothing in this Section 4.2.4(c) shall
limit the provisions of Section 2.2 hereof.

          4.2.5  Noncompetition.
                 -------------- 

          (a)  As additional consideration for the payments to be made by Buyer
hereunder, Cyprus Amax agrees for five (5) years from the Closing Date, not to
directly or indirectly, including through Affiliates, engage or have any
material ownership interest (except as provided below) in a business that
engages in, or otherwise, directly or indirectly, manages, operates or controls
a business engaged in the activities of (i) the extracting of lithium from
spodumene ore, brine or other natural conditions or (ii) the processing, sale,
marketing or exploitation of products (including downstream products derived
therefrom) where the primary component which is the subject of such activities
is lithium (collectively, the "Prohibited Activities").  Nothing contained in
this Section shall limit the activities of Cyprus Amax or its Affiliates with
respect to (i) any business acquired after the date hereof if the Prohibited
Activities did not generate greater than 25% of the revenues of such business
during its fiscal year immediately prior to the acquisition and if the
Prohibited Activities would not constitute a "significant subsidiary" (as
defined in the rules and regulations under the Securities Exchange Act of 1934)
of Foote if Foote were to acquire such business, or (ii) any business conducted
by an entity which hereafter directly or indirectly acquires Cyprus Amax.  In no
event shall the ownership of a passive interest less than five percent of any
publicly traded company be deemed to be a violation of this Section.

                                      -28-

<PAGE>
 
          (b)  The parties agree that the duration and area (which shall be
worldwide) for which the covenant not to compete set forth in this Section 4.2.5
is to be effective are reasonable.  In the event that any court of competent
jurisdiction determines that the time period or area provided for in this
Section 4.2.5., or both of them, are unreasonable and that such covenant is to
that extent unenforceable, such covenant shall remain in full force and effect
for the greatest time period and in the greatest geographical area that would
not render it unenforceable.

          (c)  The parties agree that damages would be an inadequate remedy for
Buyer in the event of a breach or threatened breach of this Section and thus, in
any such event, Buyer may, either with or without pursuing any potential damage
remedies, immediately seek to obtain and enforce an injunction prohibiting
Cyprus Amax and its Affiliates from violating this Section.

          4.2.6  No Solicitation by Cyprus Amax.  Commencing on the date of this
                 ------------------------------                                 
Agreement and ending on the third anniversary of the Closing Date, Cyprus Amax,
on behalf of itself and its Affiliates, agrees not to hire or attempt to hire
any employees of the Company, other than those persons (i) identified on
Schedule 4.2.6, (ii) responding to advertisements of general solicitation, (iii)
who have been terminated by the Company, or (iv) who, after one (1) year from
Closing, approach without solicitation, Cyprus Amax or its Affiliates.

          4.2.7  Confidentiality.  For seven (7) years following Closing,
                 ---------------                                         
neither Cyprus Amax nor Specialty shall directly or indirectly, disclose to any
third party or use for any purpose other than as contemplated by this Agreement,
any confidential information regarding the Company.  The preceding sentence
shall not apply to information which (i) was or becomes generally available to
the public other than as a result of disclosure by Cyprus Amax, Specialty or
their Affiliates, (ii) becomes available to Cyprus Amax, Specialty or their
Affiliates from a Person other than the Company or its representatives who is
not, to the Knowledge of Cyprus Amax, Specialty or their Affiliates bound by a
confidentiality agreement with the Company, or (iii) is compelled to be
disclosed pursuant to any requirement of Law, court order, subpoena, or similar
legal authority provided, that, Cyprus Amax shall give the Company prompt notice
thereof and mark all information so disclosed as confidential business
information of the Company.  Cyprus Amax shall advise the Company of any such
requirement to disclose any such confidential information, so that the Company
may seek appropriate legal relief.

SECTION 4.3  JOINT COVENANTS AND AGREEMENTS
             ------------------------------

          All obligations of the Company contained in this Section 4.3 shall be
deemed, upon Closing, to have been solely obligations of Cyprus Amax to cause
the Company to take such actions, and shall not be deemed to have been direct
obligations of the Company.

          4.3.1  No Acts or Omissions.  No party shall intentionally and in bad
                 --------------------                                          
faith perform any act which, if performed, or omit to perform any act which, if
omitted to be performed, would prevent or excuse the performance of this
Agreement by any party hereto.

          4.3.2  Consents of Others.  Each party shall use its reasonable
                 ------------------                                      
efforts prior to the Closing to obtain all authorizations, consents and permits
required of them to permit them to consummate the transactions contemplated by
this Agreement or the Related Agreements; provided that as to consents, Cyprus
Amax's obligations shall be limited to the Material Restricted Contracts and
Cyprus Amax shall have no liability from its failure to obtain any consent with
respect to any Material Restricted Contract.  In addition, while the parties
believe that the DOJ Consent Order is not applicable to the transactions
contemplated hereby, they agree to use all reasonable efforts to cause the Order
to be vacated or modified to the extent necessary to fulfill the Closing
conditions.  Each party shall promptly file with the Federal Trade Commission
and the Antitrust Division of the United States Department of Justice a pre-
merger notification in accordance with the HSR Act with respect to the sale of
the Company Shares.  The parties shall reasonably cooperate to expedite the
termination of the waiting period under the HSR Act.

          4.3.4  Publicity.  During the period prior to the Closing, each party
                 ---------                                                     
shall obtain the other party's consent before issuing any press release or
otherwise making any public announcement with respect to this Agreement, and
shall not issue any such press release or make any such public announcement
prior to obtaining such consent, which consent shall not be unreasonably
withheld or delayed, except as may be required by law or by obligations under
any listing agreement with a stock exchange.

          4.3.5  Name Change.  At the Closing, the parties shall take all
                 -----------

which is not similar to, and does not employ any portions of the name of Cyprus
Amax.

Partnership.

          (b)  Effective as of, or prior to, the Closing, Cyprus Amax and the
Company shall take such action as is necessary to substitute Cyprus Amax for the
Company as the sponsoring employer of the Pension Plan for Certain Hourly-Rated
Employees of Cyprus Foote Mineral Company (the "Foote Plan").  Effective as of
the Closing, employees of the Company shall cease to participate in the Foote
Plan and the Company shall cease to be a participating employer thereunder.  As
of the Closing, employees of the Company shall be fully vested in their accrued
benefits under the Foote Plan, determined as of the Closing.  Effective as of
the Closing, employees of the Company shall accrue no additional benefits under
the Foote Plan and shall accumulate no further years of service thereunder after

Company in accordance with the terms of the Foote Plan.

          (c)  Effective as of the Closing, employees of the Company shall cease
to participate in the Cyprus Amax Minerals Company Savings Plan and Trust (the

Savings Plan.

          (d)  Effective as of the Closing, Buyer shall cause the Company to
adopt or to become a participating employer in a savings plan that qualifies
under Sections 401(a) and 401(k) of the Code.  Such plan shall provide for the
immediate participation of the employees of the Company thereunder, and shall
allow employees of the Company to roll over into such plan distributions from
Cyprus Amax's Savings Plan, including, to the extent permitted by Law, the roll
over of an in-kind distribution of any outstanding loan balances and shares of
common stock of Cyprus Amax, provided, however, that the Company shall not be
obligated (i) to permit employees to make any additional investments in shares
of common stock of Cyprus Amax, or (ii) to permit employees who rollover in-kind
distributions of shares of common stock of Cyprus Amax to retain such shares as
an investment for more than two years after the Closing.

short-term disability, group term life insurance, dependent life insurance,

Code with a healthcare spending account and a dependent care spending account)
that provide benefits to employees 


                                      -31-
<PAGE>
 
of the Company which shall not be materially more favorable in the aggregate
than current benefits provided to employees. The plans so established by the
Company shall be the Company Plans (as defined in Section 3.2.20). Buyer shall
cause the Company to continue to maintain such plans, subject to the Company's
right to amend or terminate such plans, on and after the Closing.

          (f)  Buyer shall cause the Company to establish a retiree medical plan
providing retiree medical benefits for current employees of the Company as of
the Closing who meet the eligibility requirements thereunder.  Buyer shall cause
the Company not to amend or terminate such plan until December 31, 1998, or such
later date determined by Buyer.

          (g)  Effective as of the Closing, Buyer shall cause the Company to
adopt a severance pay plan with terms and conditions substantially similar to
those of Cyprus Amax's severance pay plan as it applies to employees of the
Company.  The plan so established by the Company shall be a Company Plan (as
defined in Section 3.2.20).  Buyer shall cause the Company not to amend or
terminate such plan for at least twelve (12) months after the Closing.  No
severance or other payment shall be payable by the Company under such plan as a
result of the change of control or other events caused by the transactions
contemplated herein.

          (h)  Nothing in this Agreement, expressed or implied, shall confer
upon Buyer, or the Company (i) except as specifically provided in Sections
4.3.6(d), (f) and (g), the obligation to continue to provide (or to provide any
benefit in lieu of) any benefits currently provided to current and former
employees under the Plans for any specific period of time after the Closing,
(ii) the obligation to continue to employ any employee of the Company for any
specific period of time after the Closing or otherwise interfere with the right
of Buyer or the Company to terminate any such employee at any time for any
reason, subject to applicable Law, or (iii) require Buyer or the Company to
continue to provide (or provide any benefit in lieu of) benefits that are paid
in or based on the value of any stock or other securities of Buyer or the
Company or that consist of options or other rights to buy such stock or
securities.

          4.3.7  Notice of Breach; Cure of Breach.  Prior to the Closing, Cyprus
                 --------------------------------                               
Amax and Specialty on the one hand, and Buyer on the other hand, shall promptly
notify the other if the notifying party has knowledge of a breach of this
Agreement by the other party.  If a breach is cured (whether or not the subject
of a notice) prior to the time established for the Closing, such breach shall be
deemed not to have occurred for all purposes of this Agreement.  In the event
that any party is in breach of this Agreement, it may elect, on one occasion,
upon notice to the other parties to defer the Closing to a date not later than
seven (7) days after the date on which the Closing would otherwise have occurred
to allow for cure of such breach.

     SECTION 5.5  INSURANCE AND THIRD PARTY CLAIMS

          5.5.1  Policies.  Cyprus Amax and the Company have experienced losses
                 --------                                                      
with respect to Environmental Matters (i) as to which potential recoveries with
respect thereto are not reflected as assets on the March 1998 Balance Sheet, and
(ii) that they


                                      -39-
<PAGE>
 
contend are insured ("Pre-Closing Insured Losses") under historic insurance
policies, including (without limitation) certain comprehensive general, umbrella
and excess liability insurance policies described on Schedule 4.3.9, (all of
such policies, whether or not so listed, being the "Foote Policies").  Some or
all of the Company's predecessor or subsidiary or affiliated entities, including
(without limitation) Vanadium Corporation of America were also insured under
other historic insurance policies, as well as under the Foote Policies (the
"Foote-Vanadium Policies").  Cyprus Amax also may incur losses relating to
Cyprus Amax Responsibilities that it contends are insured under these policies.
(Hereafter the Foote Policies and the Foote-Vanadium Policies, together with
such other historic liability policies as may from time-to-time be discovered or
documented by the Company or by Cyprus Amax, shall be referred to collectively
as the "Historic Liability Policies.").

          5.5.2  Claims.  With respect to the Pre-Closing Insured Losses and the
                 ------                                                         
Cyprus Amax Responsibilities only (the "Covered Losses") if a Covered Loss is
covered by a Historic Liability Policy, the Company shall assign and, following
the Closing, Buyer shall cause the Company to assign claims under the Historic
Liability Policy to Cyprus Amax, and Cyprus Amax shall be subrogated to all
rights with respect to such claim under the Historic Liability Policy.  The
Company hereby irrevocably appoints Cyprus Amax as its limited agent and
attorney-in-fact to manage and administer the Historic Liability Policies in the
name of the policy owner and to make and receive the benefit of claims
thereunder relating to Covered Losses.  As the Company's limited agent and
attorney-in-fact, Cyprus Amax, at its sole expense, may prosecute claims, accept
payments, and discharge obligations and rights, in whole or in part, arising
under the Historic Liability Policies relating to Covered Losses and shall be
entitled to all proceeds recovered by the Company or otherwise in connection
therewith.  The Company shall cooperate with Cyprus Amax in connection therewith
(including as provided in Section 8.3).  This limited agency and attorney-in-
fact appointment is coupled with an interest and shall be irrevocable.  To the
extent that there are multiple claims of multiple parties against a single
Historic Liability Policy which in the aggregate exceed any alleged policy
limits, subject to the remainder of this Section, the proceeds shall be applied
in order of priority determined by the date of notice of a claim provided to the
carrier (i.e. the earlier claim has priority).  Any two or more notices of
claims provided by different parties under the same policy after the date hereof
and within the same calendar year shall be deemed to be given for purposes of
the prior sentence on the same date.  If, as a result of such claims, any such
policy limit is exhausted such that at least one of such claims is not fully
satisfied, the parties shall allocate between themselves the aggregate proceeds
received by them in a proportion equivalent to the respective losses that each
would have been entitled to recover under the policy, without regard to any
policy limits.

          5.5.3  Other Third Party Claims.  In the event that there are any
                 ------------------------                                  
claims in existence or hereafter arising against third parties (as to which
potential recoveries with respect thereto are not reflected as assets on the
March 1998 Balance Sheet) 



                                      -40-
<PAGE>
 
arising out of (i) losses previously incurred by Cyprus Amax or the Company with
respect to Environmental Matters, or (ii) Cyprus Amax Responsibilities, the
Company hereby assigns all rights thereto to Cyprus Amax and hereby irrevocably
appoints Cyprus Amax as its limited agent and attorney-in-fact for pursuing such
claims and agrees to cooperate with Cyprus Amax in connection therewith
(including as provided in Section 8.3). This limited agency and attorney-in-fact
appointment is coupled with an interest and shall be irrevocable.

except as to matters arising from the date of this Agreement through the Closing
in the ordinary course of business (and not in violation of a covenant) or
otherwise contemplated by this Agreement, and also except for such instances
which in the aggregate could not reasonably be expected to result in a Material

after the date hereof or coming to the attention of Cyprus Amax as having caused

Buyer, nevertheless, decides to Close, the breach or failure shall be deemed
cured and may not be relied upon by Buyer or the Company to avoid any of their
obligations hereunder, impose any liabilities or obligations upon Cyprus Amax or
Specialty or otherwise recover from Cyprus Amax or Specialty with respect
thereto, or (ii) if Buyer decides not to Close, this Agreement and the proposed
transactions contemplated hereunder shall terminate, and each party hereto shall

of a failure of a condition or breach, whether in contract, tort or otherwise,
shall be to refuse to complete the Closing under this Agreement.

otherwise been terminated.  No suit or proceeding which remains pending at the
time for Closing shall have been commenced by any Governmental Authority to
restrain, enjoin or hinder, or to seek material damages on account of the
consummation of the transactions herein contemplated.  The DOJ Consent Order
shall have been vacated or modified to permit the transactions contemplated

or operation by Buyer and its Affiliates of the Company following the Closing.

other order by any federal or state court in the United States, or any court in
any other country, of competent jurisdiction which prevents the consummation of
the transactions contemplated by this Agreement or by the Related Agreements or
prohibits or limits materially the ownership and operation by Buyer of all or
any material portion of the business or assets of the Company shall have been
issued and remain in effect (each party agreement to use all commercially
reasonably efforts to have any such injunction lifted).

          6.1.4  Opinions of Counsel.  Buyer shall have received legal opinions
                 -------------------

approval or other form of acquiescence to the continuation following Closing of
the Sales Agency Agreement between Foote and the Chilean Partnership, provided
that if Cyprus provides a notice to Buyer that it is deleting this exception
with respect to the Sales Agency Agreement from Schedule 3.2.13, this Section
6.1.5 shall be deemed to be terminated and of no further effect.

          6.1.6  Buyer's Receipt of the Closing Documents.  Buyer shall have

(including the Schedules hereto) or any certificate delivered by either of them
in connection herewith.

SECTION 9.4  PROCEDURE FOR THIRD PARTY CLAIMS
             --------------------------------

             An indemnified person shall give prompt written notice, specifying
with particularity the facts underlying the matter, to the indemnifying person
of any claim, suit, action, proceeding or demand of which such indemnified
person has received notice from a third party (that is, a party other than a
party to this Agreement) and as to which such indemnified person has reason to
believe that it may be entitled to indemnification under this Agreement
(provided, however, that any failure to give such notice shall not relieve the
- ---------  -------                                                            
indemnifying person from liability hereunder to the extent such party is not
prejudiced thereby).  The indemnifying person shall have the right to
participate in or assume and direct the defense and resolution at its own
expense against any such matter, in its name or in the name of the indemnified
person, as the case may be, and with counsel selected by the indemnifying
person; provided, however, that if an order, injunction or other equitable
        --------  -------                                                 
relief against the indemnified person is being sought (collectively, "Equitable
Relief"), then the indemnified person may employ separate counsel at the
indemnifying person's expense and participate in and direct the defense of such
matter to the extent necessary to protect its interest with respect to Equitable
Relief.  Except as provided in the preceding sentence with respect to Equitable
Relief, after notice from the indemnifying person of its election to assume the
defense thereof, the indemnifying person shall not be liable to the indemnified
person for any legal or other expense incurred by the indemnified person in
connection with such claim.  The indemnified person shall have the right to
participate in the defense of any matter so assumed, with separate counsel
selected by it and at its own expense.  The indemnified person shall cooperate
with the indemnifying person, and keep the indemnifying person reasonably
informed, in the participation or defense of any such matter.  The indemnifying
person will not settle or compromise any such pending matter, without the prior
written consent of the indemnified person, which consent shall not be
unreasonably withheld.  If the 


                                      -48-
<PAGE>
 
indemnifying person does not elect to assume and direct the defense of such
matter, the indemnified person shall defend such matter in a competent and
diligent manner and may settle or compromise such pending matter, upon receiving
the prior written consent of the indemnifying party, which consent shall not be
unreasonably withheld.

SECTION 9.5  PROCEDURE FOR DIRECT CLAIMS
             ---------------------------

             An indemnified person shall give prompt written notice, to an
indemnifying person of any claim it may have for indemnification under this
Article IX, specifying with particularity the facts underlying the claim;
provided, however, that any failure to give such notice, shall not relieve the
- --------  -------                                                             
indemnifying person from liability thereunder to the extent such party is not
prejudiced thereby, provided that such notice is given within any applicable
survival period.

SECTION 9.6  GENERAL PROVISIONS RELATING TO REMEDIES AND INDEMNIFICATION
             -----------------------------------------------------------

             9.6.1  (a) Neither Cyprus Amax nor Specialty shall be required to
make any payments pursuant to Articles V or IX (these being the only Articles in
addition to Article II, pursuant to which payment may be required hereunder)
relating to breach of a representation or warranty unless and until the
aggregate amount of all Losses for breach of representations and warranties
shall exceed $4 million, as to which Cyprus Amax and Specialty shall thereafter
be responsible only for the excess of the aggregate of such Losses over $4
million (the "Deductible"). The Deductible, however, shall not be applicable to
breaches of Sections 3.2.7, 3.2.8 or 3.2.22(b).

             (b)  The maximum aggregate amount recoverable hereunder from Cyprus
Amax or Specialty for breaches of all representations or warranties shall be
$100 million, provided that (i) as to a breach or breaches of Sections 3.2.7,
3.2.8 and 3.2.20 (the "Primary Sections"), such aggregate limit shall be (x) the
Purchase Price, less (y) all other indemnified Losses from breaches of all other
representations and warranties other than the Primary Sections; and provided
further that (ii) as to a breach or breaches of Section 3.2.22(b), the aggregate
limit shall be (x) $183 million, less (y) all indemnified Losses from breaches
of representations and warranties under all Sections other than Section
3.2.22(b).

             9.6.2  No party shall have any obligation to indemnify a party for
any Losses to the extent they represent the cost of repairs, replacements or
improvements which enhance the value of the repaired, replaced or improved asset
above its value on the Closing Date.

             9.6.3  No party shall bring a claim or be entitled to
indemnification with respect to any acts, omissions or circumstances resulting
in a breach of any representation, warranty, covenant or agreement, which acts,
omissions or circumstances it had actual knowledge of on or before the Closing
Date. Except as


                                      -49-
<PAGE>
 
provided in Section 6.1.1, the foregoing provisions shall not limit any
claims or entitlement of Buyer for indemnification with respect to any such
acts, omissions or circumstances of which Cyprus Amax had Knowledge of on or
before the date hereof.

          9.6.4  An indemnifying Person shall have no obligation to indemnify an
indemnified Person or otherwise have liability to an indemnified Person for
consequential damages, incidental damages or similar items except with respect
to Losses incurred by an indemnified Person pursuant to an award in favor of a
third party.

          9.6.5  An indemnified Person shall take all reasonable steps to
mitigate all indemnifiable Losses upon and after becoming aware of any event
which could reasonably be expected to give rise to any Losses that are
indemnifiable hereunder.

          9.6.6  (a) Each party's Losses shall be reduced by any realizable
federal and state income tax reductions or other benefits which are available in
connection with the Losses, after giving effect to any tax detriment to the
indemnified party arising from the receipt of the indemnification payment with
respect to such Losses.

          9.6.7  If any Loss is covered by insurance or subject to other third
party recoveries (collectively, "Third Party Rights"), Buyer shall use
commercially reasonable efforts to recover or cause the Company to recover, the
amount of coverage or claim from the insurer or such third party, which recovery
(after deduction of costs of collection) shall reduce Losses hereunder.  Buyer
agrees to assign or cause the Company to recover, all Third Party Rights to
Cyprus Amax and to appoint Cyprus Amax as its limited agent and attorney-in-fact
for seeking such recovery to the extent Buyer fails to recover, does not timely
proceed with recovery actions, or obtains excess recovery with respect thereto,
and to cooperate with Cyprus Amax in the collection thereof.  Such appointment
as limited agent and attorney-in-fact is coupled with an interest and is
irrevocable.  To the extent that Cyprus Amax or Specialty on the one hand, or
Buyer or the Company on the other hand, discharges any claim for indemnification
hereunder, it shall be subrogated to all related rights of the other party
against third parties.

SECTION 9.7  EXCLUSIVE NATURE
             ----------------

          9.7.1  The indemnification provisions of Articles V and IX and the
applicable provisions of the Tax Sharing and Indemnification Agreement shall be
the exclusive remedy against Cyprus Amax, Specialty, Buyer and its Affiliates
and their officers, directors, employees, shareholders, partners, Affiliates,
agents or representatives, following the Closing for any breaches or alleged
breaches of any representation, warranty or other provision of this Agreement or
the transactions contemplated hereby except for non-monetary remedies being

or covenant contained herein which requires performance on or after Closing and
except for matters arising from the fraud of Cyprus Amax or Specialty. No party
shall have any right to setoff any claims hereunder against any payments to be
made by such party to another party pursuant to this Agreement or otherwise.

          9.7.2  Each of the parties hereto, on behalf of itself and its
officers, directors, employees, shareholders, partners, Affiliates, agents or
representatives (collectively, such party's "Representatives") agrees not to
bring any actions or proceedings, at law, in equity, in tort or otherwise,
against any other party or its Representatives, in respect of any breaches or
alleged breaches of any representation, warranty or other provision of this
Agreement, except pursuant to and subject to the express provisions of Articles
V and IX, including, without limitation, Section 9.7.1.

     This SUPPLEMENTAL AGREEMENT entered into this 13 day of October, 1998 by
and among the parties listed on the signature page hereto (the "Parties").

     WHEREAS, the Parties have entered into a Stock Purchase and Sale Agreement
as of April 25, 1998 (the "Stock Purchase Agreement") and a Tax Sharing
Agreement and Indemnification Agreement as of October 13, 1998 (the "Tax
Sharing and Indemnification Agreement"); and

     WHEREAS, the Parties wish to amend certain provisions thereof;

     NOW, THEREFORE, the Parties hereby agree as follows:

1.   (A)  THE FOLLOWING DEFINITIONS CONTAINED IN SECTION 1.1 OF THE STOCK
PURCHASE AGREEMENT SHALL BE AMENDED AND RESTATED AS FOLLOWS:

          "Book Value" shall mean the assets less the liabilities of the Company
as of the Financial Closing Date, computed in a manner consistent with the 1997
Balance Sheet and the principles on Annex B (which principles shall take
precedence over any other principles employed in the 1997 Balance Sheet).

          "Chilean Partnership" means Sociedad Chilena de Litio Limitada, a
limited liability partnership organized under the laws of Chile and, unless the
context otherwise requires, shall also include Minera Cyprus Amax Chile Limitada
(until its disposition by the Company pursuant to the Chilean Restructuring) and
Foote Minera Inversiones Ltda., and Foote Chile Holding Company, upon their
direct or indirect ownership by the Company pursuant to the Chilean
Restructuring.

          "Working Capital Value" shall mean the sum of certain current assets
less the sum of certain current liabilities of the Company as of the Financial
Closing Date, computed in a manner consistent with the 1997 Balance Sheet and
the principles contained on Annex B (which principles shall take precedence over
any other principles employed in the 1997 Balance Sheet).

(B)  THE FOLLOWING DEFINITION SHALL BE ADDED TO SECTION 1.1 OF THE STOCK
         PURCHASE AGREEMENT:

          "Financial Closing Date" shall mean as of 12:01 a.m. Eastern Standard

                                      -1-
<PAGE>
 
3.   SECTIONS 2.2.1 AND 2.2.3 OF THE STOCK PURCHASE AGREEMENT SHALL BE AMENDED
     AND RESTATED AS FOLLOWS:

          2.2.1  Within sixty (60) days following the Financial Closing Date,
Cyprus Amax shall prepare and deliver to Buyer, a consolidated balance sheet of
the Company as of the Financial Closing Date (the "Closing Balance Sheet")
prepared in a manner consistent with the 1997 Balance Sheet (but subject to the
principles set forth on Annex B), together with a computation of the Working
Capital Value as of the Financial Closing Date (the "Working Capital Value
Computation") and Book Value as of the Financial Closing Date (the "Book Value
Computation").  The Closing Balance Sheet shall be accompanied by the Report of
Price Waterhouse LLP (at the cost of Cyprus Amax), stating that the accounting
principles reflected in the Closing Balance Sheet conform, in all material
respects, to the requirements of this Section.  Buyer and the Company shall
provide Cyprus Amax's representatives reasonable access to the books and records
of the Company and shall cause the Company's employees to provide reasonable
assistance to Cyprus Amax, both in connection with the preparation of the
Closing Balance Sheet, as well as any dispute with respect thereto.  Cyprus Amax
shall cause Price Waterhouse LLP to coordinate with Buyer's accountants, if
requested by Buyer, in connection therewith.

          2.2.3  (a) In the event that the actual Working Capital Value as so
determined is greater or less than $31,984,000 then:

                 (i)  if greater (such amount being the "Working Capital
                      Excess"), Buyer shall pay to Specialty the amount of such
                      excess, and

                 (ii) if less (such amount being the "Working Capital
                      Deficiency"), Cyprus Amax shall cause Specialty to pay to
                      Buyer the amount of such deficiency.

                 (b) In the event that the Book Value as so determined is less
than: (i) $132,765,000 less (ii) the amount of any Working Capital Deficiency,
or plus (iii) the amount of any Working Capital Excess,

then Specialty shall pay to Buyer and Cyprus Amax shall cause Specialty to pay
to Buyer the amount of such deficiency.  Buyer may offset any amount payable by
Specialty under (b) against any amount payable by Buyer under (a)(i).

                 (c) Such payments shall be made by check or wire transfer
within forty-five (45) days after delivery by Cyprus Amax to Buyer of the
Closing Balance Sheet, or five (5) business days after the resolution of any
objection pursuant to Section 2.2.2, whichever is later, with such payment
accompanied by interest at seven percent (7%) per annum from the Financial
Closing Date.

                                      -2-

4.   SECTION 4.2 OF THE STOCK PURCHASE AGREEMENT SHALL BE AMENDED AND RESTATED
AS FOLLOWS:

     4.2.4  Intercompany Accounts; Cash Accounts.
            ------------------------------------ 

               (a) All intercompany accounts, including any intercompany
promissory notes, providing for the payment of any amounts between the Company
(including the Chilean Partnership) on the one hand, and Cyprus Amax and its
Affiliates (other than the Company and the Chilean Partnership) on the other
hand, shall be settled via dividend to the extent of retained earnings and then
a return of capital if the amount is a receivable on the Company books as of the
Financial Closing Date, or as an increase of paid-in capital if the amount is a
payable on the Company books as of the Financial Closing Date, with no cash or
other payments being made. Notwithstanding the foregoing sentence, intercompany
transactions resulting from the Chilean Restructuring shall be settled without
cash based on intercompany balances through the Closing Date, in lieu of the
Financial Closing Date. Nothing in this Section 4.2.4(a) shall limit the
provisions of Section 2.2 hereof.

               (b)  Except as otherwise contemplated by this Agreement, all
agreements between the Company (including the Chilean Partnership) on one hand,
and Cyprus Amax and its Affiliates (other than the Company or the Chilean
Partnership) on the other hand, each of which are set forth on Schedule
4.2.4(b), shall be terminated and of no further force and effect, as of the
Closing Date.

               (c) At or before the Closing, all cash and cash equivalents of
the Company (including the Chilean Partnership) as of the Financial Closing Date
will be transferred to Cyprus Amax or its Affiliates for no consideration (the
"Financial Cash Transfer"); provided, however, that approximately $207,500 of
cash and cash equivalents of the Company (including the Chilean Partnership)
(the "Retained Cash") will not be transferred to Cyprus Amax or its Affiliates
to enable the Company to maintain certain cash balances during the ownership
transition. An amount equal to the Retained Cash shall be paid by the Buyer or
the Company to Specialty no more than thirty (30) days following the Closing
Date, with such payment accompanied by interest at seven percent (7%) per annum
from the Closing Date. Nothing in this Section 4.2.4(c) shall limit the
provisions of Section 2.2 hereof. For purposes of clarity, the Financial Cash
Transfer shall reflect earnings through the Financial Closing Date and shall not
reflect earnings from the Financial Closing Date through the Closing Date which
shall accrue to the benefit of Buyer (although cash generated during this period
may be used to fund such transfer but not in the aggregate in excess of the
amount as of the Financial Closing Date).

5.   SECTION 6.1.5 AND SCHEDULE 3.2.13 OF THE STOCK PURCHASE AGREEMENT SHALL
     REFLECT THE FOLLOWING CHANGE:

     Pursuant to Section 6.1.5, Cyprus Amax is hereby providing notice to Buyer
that it is deleting from Schedule 3.2.13 the asterisk and the exception that the
possible consent of the Chilean Central Bank may be required with respect to
change of control of the Company under the Sales Agency Agreement.

                                      -3-
<PAGE>
 
Except as expressly provided herein, the Stock Purchase Agreement shall remain
in effect in accordance with its terms.

6.   SCHEDULE 3.2.16 OF THE STOCK PURCHASE AGREEMENT SHALL BE AMENDED AND
     RESTATED AS FOLLOWS:

     By deleting the Chilean Restructuring Schedule attached to the Stock
     Purchase Agreement and replacing it with Annex A.

7.   SECTION 9.2 OF THE STOCK PURCHASE AGREEMENT SHALL BE AMENDED AS FOLLOWS:

     By deleting the phrase which reads "or any certificates delivered to Cyprus
     Amax" with the phrase "or any certificates delivered by Cyprus Amax"

8.   SECTION 19(D) OF THE TAX SHARING AGREEMENT SHALL BE AMENDED TO INSERT THE
     FOLLOWING SENTENCE:

     Seller and Buyer agree that the purchase price allocated to the Chilean
     Partnership shall not exceed $100,000,000.

9.   SECTION 3.2.26 SHALL BE ADDED TO THE STOCK PURCHASE AGREEMENT AS FOLLOWS:

                                    ANNEX A
               The Chilean Restructuring was modified as follows:


STEP 1    FORMATION OF CHILEAN NEWCO NON-LITHIUM
          --------------------------------------

          Pursuant to a deed of division and related documents, the non-lithium
          assets and liabilities of Sociedad Chilena de Litio Limitada (Chile)
          ("SCL") will be transferred to SCL Exploraciones Limitada, a Chilean
          limitada owned by SCL's partners, (55%) Cyprus Foote Mineral Company
          (Pennsylvania) ("Company") and (45%) Minera Cyprus Amax Limitada
          (Chile) ("MCA"), respectively.

STEP 2    FORMATION OF FOOTE MINERA E INVERSIONES LIMITADA
          ------------------------------------------------

          Pursuant to a deed of division and related documents, the lithium
          assets and liabilities of MCA will be transferred to Foote Minera e
          Inversiones Limitada owned equally by MCA's partners, (50%) Company
          and (50%) Cyprus Specialty Metals Company (Delaware) ("Specialty").

STEP 3    TRANSFER BY COMPANY OF (55%) SCL EXPLORACIONES LIMITADA  TO MCA
          ---------------------------------------------------------------

          The Company will transfer its interest in SCL Exploraciones Limitada
          to MCA in return for additional capital in MCA.  The Company's entire
          interest in the non-lithium assets and liabilities which were owned by
          SCL will now be owned by MCA.  As a result of this transfer, SCL
          Exploraciones Limitada will be absorbed into MCA.

STEP 4    TRANSFER BY THE COMPANY OF ITS NON-LITHIUM INTEREST IN MCA
          -----------------------------------------------------------

          The Company will transfer its interest in MCA and its interest in
          Minera Cyprus Chile Limitada to Cyprus Amax Chile Holdings, Inc.
          (Delaware)  owned by a Cyprus Amax affiliate.  After this step, the
          Company will no longer own non-lithium assets.

STEP 5    TRANSFER BY SPECIALTY OF ITS INDIRECT OWNERSHIP IN LITHIUM ASSETS TO
          --------------------------------------------------------------------
          THE COMPANY
          -----------

          The remaining interest in SCL (45%) owned indirectly by Specialty will
          be transferred to the Company by Specialty through the transfer of
          Specialty's 50% interest in Foote Minera e Inversiones Limitada  to
          Foote Chile Holding Company.    Foote Chile Holding Company will then
          be transferred 

                                      -6-
<PAGE>
 
          to the Company. After this step, all lithium assets will be owned
          indirectly by the Company.

                      or any of their Tax Affiliates whether occurring before,
                      on, or after the Closing Date (the "Separation

                      imposed on the transfers consummated under the Stock

will not include any Taxes arising as a result of actions taken by the Company,
or by Buyer or any of their Tax Affiliates with respect to the Company, on the

     Any reference in this Agreement to the Company will be deemed to include a
reference to any Subsidiaries of the Company immediately prior to the Closing.

     3.  Straddle Periods.
         ---------------- 

     (a) With respect to any taxable period of the Company or any of its Tax
Affiliates that would (absent an election) include, but not end until after, the
Closing Date (a "Straddle Period"), Buyer and Seller will, to the extent
permitted by applicable law, elect with the relevant Tax authority to close such
Straddle Period as of the close of the Closing Date.  As a result of such
election, Taxes will be allocated to Seller and Buyer pursuant to the provisions
of Sections 2 and 4, respectfully; provided, however, that notwithstanding any
                                   --------  -------                          
provision to the contrary 

                                      -4-
<PAGE>
 
contained in this Agreement, Seller will not be responsible for any Taxes to the
extent accrued as a liability of the Company or any of its Tax Affiliates in the
determination of the Working Capital Value and Book Value.

     (b) Except as provided in Section 3(c), in any case where applicable law
does not permit the Company or any of its Tax Affiliates to close a Straddle
Period as of the close of the Closing Date, Seller will be allocated any Income
Taxes imposed on the Company or such Tax Affiliates for the portion of the
Straddle Period up to and including the Closing Date.  For purposes of this
Section 3(b), Income Taxes for the portion of a Straddle Period up to and
including the Closing Date will be determined based upon an interim closing of
the books of the Company or such Tax Affiliates as of the Closing Date based
upon tax accounting practices and procedures used by the Company or such Tax
Affiliates in preparing its Tax Returns; provided, however, that such Income
                                         --------  -------                  
Taxes will not include any Income Taxes arising as a result of actions taken by
the Company, or by Buyer or any of their Tax Affiliates with respect to the
Company, on the Closing Date but after the Closing that are not in the ordinary
course of business of the Company.

     (c) With respect to any Straddle Period, Chilean Income Taxes initially
will be allocated to Seller based upon Seller's preparation of a pro forma Tax
Return for the portion of the Straddle Period up to and including the Financial
Closing Date (the "Chilean Pro forma Tax Return").  Within one hundred and
twenty (120) days following the Closing, Seller shall prepare and deliver to
Buyer, the Chilean Pro forma Tax Return prepared in a manner consistent with
past Tax accounting practices.  Buyer shall provide Seller's representatives
reasonable access to the books and records of the Company and shall cause the
Company's employees to provide reasonable assistance to Seller, both in
connection with the preparation of the Chilean Pro forma Tax Return, as well as
any dispute with respect thereto.  Buyer shall have the right within sixty (60)
days following the delivery of the Chilean Pro forma Tax Return to object in
writing to the allocation of Chilean Income Tax based thereon, specifying in
reasonable detail the basis for such objection(s).  Buyer shall be deemed to
have agreed to file Chilean Income Tax Returns with all items and amounts
contained in the Chilean Pro forma Tax Return, except as specifically objected
to in such notice.  If Buyer does so object, Seller and Buyer shall cooperate
with each other to attempt to reach a mutual agreement thereon, or, failing such
agreement within twenty (20) days, the determination shall be made by the
Accountant pursuant to the dispute resolution provisions contained in Section
16.  Nothing contained in this Section 3(c) shall be deemed to limit the rights
of the Company, Buyer or their Tax Affiliates to obtain indemnification from
Seller with respect to Chilean Income Taxes, including, without limitation,
their right to indemnification under Section 2 hereof.

     (d) As to any Tax other than an Income Tax (a "Non-Income Tax"), for any
Straddle Period, Seller will be allocated (i) for any Non-Income Tax that is

                                      -5-
<PAGE>
 
determined based upon specific transactions (including, but not limited to,
value added, sales and use Taxes), all Non-Income Taxes applicable to
transactions which have occurred during the period through the Financial Closing
Date and (ii) for any Non-Income Tax that is not based upon specific
transactions (including, but not limited to, license, real property, personal
property, franchise and doing business Taxes), any Non-Income Tax equal to the
full amount of such Non-Income Tax for the entire Straddle Period multiplied by
a fraction, the numerator of which is the number of days in the Straddle Period
ending on the Financial Closing Date and the denominator of which is the number
of days in the entire Straddle Period.

     4.  Taxes Allocated to Buyer and the Company. Buyer and the Company will be
         ----------------------------------------
responsible for, will pay or cause to be paid, and will indemnify and hold
harmless Seller and its Tax Affiliates from and against any and all Taxes other
than those for which Seller is responsible pursuant to Sections 2 and 3 hereof,
including, without limitation, Taxes attributable to periods ending after the
Closing Date (other than any Taxes allocated to Seller pursuant to Sections 2 or
3 hereof).

     5.  Refunds of Indemnified Taxes.
         ---------------------------- 
     (a) Buyer will remit (and will cause the Company and its Tax Affiliates to
remit) to Seller within five business days of receipt an amount equal to all
refunds (including interest thereon and any amounts applied against a Tax
liability for other taxable periods) of any Taxes for which Buyer is indemnified
pursuant to this Agreement ("Seller's Refunds") (including but not limited to
the Chilean Refunds) net of any net Tax liability that is imposed on the Company
or any of its Tax Affiliates in connection with the receipt and remittance of
Seller's Refunds therewith.

     Seller will remit (and will cause its Tax Affiliates to remit) to Buyer
within five business days of receipt all refunds (including interest thereon and
any amounts applied against a Tax liability for other taxable periods) of any
Taxes for which Seller is indemnified pursuant to this Agreement ("Buyer's
Refunds") net of any net Tax liability that is imposed on the Seller or any of
its Tax Affiliates in connection with the receipt and remittance of Buyer's
Refunds therewith.

     (b) Upon the reasonable request of Seller, Buyer will file, or cause the
Company or its Tax Affiliates to file, claims for Seller's Refunds, in such form
as Seller may reasonably request; provided that Buyer shall not be required to
file or prosecute any such claim if it would be inconsistent with, or
detrimental to, Tax positions previously or currently adopted by the Company, in
filing its Tax Returns (in the sole reasonable judgment of Buyer).  If permitted
pursuant to the preceding sentences, Seller will have the right to prosecute any
claims for Seller's Refunds (by suit or otherwise) at Seller's expenses and with
counsel of Seller's choice (if such Counsel is reasonably satisfactory to
Buyer).  Buyer will cooperate, and cause 

                                      -6-
<PAGE>
 
the Company and their Tax Affiliates to cooperate, fully with Seller and its
counsel in connection therewith.

     Upon the reasonable request of Buyer, Seller will file, or cause its Tax
Affiliates to file, claims for Buyer's Refunds, in such form as Buyer may
reasonably request; provided that Seller shall not be required to file or
prosecute any such claim if it would be inconsistent with, or detrimental to,
Tax positions previously or currently adopted by the Company, in filing its Tax
Returns (in the sole reasonable judgment of Seller).  If permitted pursuant to
the preceding sentences, Buyer will have the sole right to prosecute any claims
for Buyer's Refunds (by suit or otherwise) at Buyer's expense and with counsel
of Buyer's choice (if such counsel is reasonably satisfactory to Seller).
Seller will cooperate, and cause its Tax Affiliates to cooperate, fully with
Buyer and its counsel in connection therewith.

     (c) For the avoidance of doubt (and except as provided in Section 6(b)
hereof), any refunds of Taxes other than Seller's Refunds and Buyer's Refunds
will be the property of the payee of such refunds and no other party to this
Agreement or its Tax Affiliates will have any right to such refunds.

     6.  Tax Benefits.
         ------------ 
     (a) Buyer will remit (or cause the Company to remit) to Seller within five
business days the amount of any Tax Benefit recognized by Buyer, the Company, or
any of their Tax Affiliates resulting from any Adjustment for which Buyer, the
Company, or any of their Tax Affiliates has been indemnified pursuant to this
Agreement.  Seller will remit to Buyer within five business days the amount of
any Tax Benefit recognized by Seller or any of its Tax Affiliates resulting from
any Adjustment for which Seller or any of its Tax Affiliates has been
indemnified pursuant to this Agreement.  For purposes of this Agreement:

                i.    "Tax Benefit" means a reduction in the amount of Taxes
                      that would otherwise be payable (net of any additional
                      Taxes that may in the future be payable), whether
                      resulting from a deduction, credit, reduced gain or
                      increased loss from the disposition of an asset, or
                      otherwise, all as determined in the reasonable judgment of
                      the "remittor" (as defined below);

                ii.   a person will be deemed to have "recognized" a Tax Benefit
                      at the time the amount of Taxes such person otherwise
                      would pay is reduced; and

                iii.  an "Adjustment" is any adjustment to (A) any individual
                      item of income, gain, loss, or deduction, or (B) any
                      individual item of credit.

                                      -7-
<PAGE>
 
     (b) If either Buyer or Seller (the "remittor") makes a remittance to the
other party (the "remittee") under Section 6(a) or Section 7(b) hereof of any
Tax Benefit and all or part of such Tax Benefit is subsequently disallowed, the
remittee will pay to the remittor within five business days that portion of such
remittance equal to the portion of the Tax Benefit that is disallowed and, in
addition thereto, any other costs or expenses incurred by the remittor in
respect to the disallowed portion of the Tax Benefit (it being agreed that the
remittor shall not suffer any cost or expense by reason of the disallowed
portion of the Tax Benefit).

     7.  Buyer to Forgo Carrybacks
         -------------------------
     (a) Unless Seller otherwise consents, Buyer will cause the Company to
forego any carryback for Tax purposes to any taxable period of the Company
ending on or before the Closing Date of any net operating loss, net capital
loss, or other deduction or credit incurred by the Company in any taxable period
ending after the Closing Date (a "Post-Closing Carryback").

     (b) If Seller consents to a Post-Closing Carryback under Section 7(a)
hereof, (i) Seller will cooperate with Buyer and the Company in filing an
appropriate refund claim or amended Tax Return, and (ii) Seller will assign and
remit to Buyer within five business days the amount of any refund of Tax
received by, or Tax Benefit recognized by, Seller or any of its Tax Affiliates
as a result of such Post-Closing Carryback.

     (c) If Seller makes any remittance to Buyer under Section 7(b) hereof and
all or part of such Post-Closing Carryback is subsequently disallowed, then
Buyer shall pay to Seller within five business days that portion of the
remittance that relates to the portion of the Post-Closing Carryback that is
disallowed and, in addition thereto, any other costs or expenses incurred by
Seller in respect to the disallowed portion of the Post-Closing Carryback (it
being agreed that Seller shall not suffer any expense or other cost by reason of
agreeing to such Post-Closing Carryback or any adjustment thereto).

     8.  No Obligation to File Amended Tax Returns. Except as otherwise
         -----------------------------------------
specifically provided in this Agreement, neither Seller nor Buyer, nor any of
their respective Tax Affiliates will be obligated to file any amended Tax Return
or other Tax refund claim.

     9.  Preparation and Filing of Tax Returns.
         ------------------------------------- 
     (a) Seller will prepare or cause to be prepared, and, to the extent
permitted by law, file or cause to be filed, (i) all consolidated, combined, or
unitary Income Tax Returns (including Chilean Income Tax Returns) of Seller or
any of its Tax Affiliates or former Tax Affiliates that include the Company and
which are listed on Schedule 9(a)(i) hereto, (ii) all Income Tax Returns
(including Chilean 

                                      -8-
<PAGE>
 
Income Tax Returns) required to be filed by or on behalf of the Company or the
Chilean Partnership for taxable periods ending (including by reason of any
election under Section 3 hereof) on or before the Closing Date and which are
listed on Schedule 9(a)(ii) hereto and all Chilean Income Tax Returns for any
such periods, and (iii) all other Tax Returns (including Chilean Income Tax
Returns) required to be filed by or on behalf of the Company or the Chilean
Partnership on or before the Closing Date in a manner consistent with the
Company's and the Chilean Partnership's past Tax accounting practices.

     (b) Buyer will prepare or cause to be prepared, and file or cause to be
filed, all Tax Returns of the Company other than those set forth in Section 9(a)
hereof.  Buyer will prepare all Tax Returns of the Company for Straddle Periods
including, but ending after, the Closing Date ("Straddle Period Returns") in a
manner consistent with the Company's past Tax accounting practice, to the extent
permitted by law, and, in the absence thereof, reasonable Tax accounting
practices selected by Buyer; provided, however, that any Tax Returns prepared by
Buyer in respect to the Company shall be prepared consistent with the Chilean
Pro forma Tax Return described in Section 3(c).  If Buyer files Straddle Period
Returns for such Straddle Periods inconsistently with such Tax accounting
practices in violation of this provision, then, any provision of this Agreement
to the contrary notwithstanding, in addition to any other remedies available,
Seller and its Tax Affiliates shall only be liable for the amount of Taxes that
would be owed by them had such Straddle Period Returns been filed consistently
with such past Tax accounting practices.

     (c) Neither Seller, nor Buyer, nor any of their Tax Affiliates will
exercise any election available under Treasury regulation (S)1.1502-76(b)(2) or
any corresponding provisions of other Tax laws for any Straddle Period.

     (d) Buyer and the Company will assist Seller in timely obtaining any
required signatures or other filing requirements in respect to Tax Returns
prepared by Seller for the Company pursuant to Section 9(a).

     (e) Upon the reasonable request, and at the expense, of either party, the
other party shall make available prior to filing (and after filing) for
inspection and copying all Tax Returns and related workpapers with respect to
Taxes to the extent that (i) such Tax Return relates to Taxes for which the
requesting party may be liable, (ii) such Tax Return relates to Taxes for which
the requesting party may be liable in whole or in part for any additional Taxes
owing as a result of adjustments to the amount of Taxes reported on such Tax
Return, (iii) such Tax Return relates to Taxes for which the requesting party
may have a claim for Tax Benefits under this Agreement, or (iv) the requesting
party reasonably determines that it must inspect such Tax Return to confirm
compliance with the terms of this Agreement.

     10.  Settlement of Actual Tax Allocations.
          ------------------------------------ 
     (a) This Section 10(a) shall govern the settlement as between Seller, Buyer
and the Company of all Straddle Period Tax allocations for Taxes that are
reported on a Straddle Period Return.

     With respect to each Straddle Period Return that involves Taxes subject to
allocation pursuant to Section 3(b) hereof, Buyer will, at least thirty (30)
days prior to the final due date (including extensions) of such Straddle Period
Return, provide to Seller (i) a copy of such Straddle Period Return (including
supporting schedules and workpapers) and (ii) a statement (including supporting
schedules and workpapers) certifying the amount of Tax shown on such Straddle
Period Return that is allocable to Seller pursuant to Section 3(b) hereof
reduced by any payments made by the Company on or prior to the Closing Date, and
by Seller and its Tax Affiliates at any time, in respect of such Taxes (whether
as estimated Taxes or otherwise) (the "Statement").  Seller and its authorized
representatives will have the right to review the Statement for ten (10) days
following Seller's receipt of the Statement (the "10-Day Review Period").  If
Seller disagrees with the allocation in the Statement, Seller will notify Buyer
in writing of such disagreement prior to close of the 10-Day Review Period, and
Seller and Buyer will consult and attempt to resolve in good faith the
disagreement.  In the event Seller and Buyer are unable to resolve the
disagreement within ten (10) days following the end of the 10-Day Review Period,
Seller and Buyer will jointly request the Accountant to resolve the disagreement
pursuant to Section 16.  Not later than five (5) days after the later of (i) the
end of the 10-Day Review Period, or (ii) if there is a disagreement, the date
notice of the resolution of the disagreement by the Accountant is provided to
Buyer and Seller, Seller will pay to Buyer or Buyer will pay to Seller, as the
case may be, an amount equal to the difference between (i) the Taxes shown on
the Statement or in such notice (as the case may be) as being allocable to
Seller pursuant to Section 3(b) hereof, and (ii) any payments made by the
Company on or prior to the Closing Date, and by Seller and its Tax Affiliates at
any time, in respect of such Taxes (whether as estimated Taxes or otherwise).

     With respect to the Chilean Income Taxes subject to allocation pursuant to
Section 3(c), not later than five (5) days after the later of (i) the end of the
Buyer's review period in Section 3(c), or (ii) if there is a disagreement, the
date notice is provided to Buyer and Seller regarding the resolution of the
disagreement by the Accountant, Seller will pay to Buyer or Buyer will pay to
Seller, as the case may be, an amount equal to the difference between (i) the
Taxes shown on the Chilean Pro forma Tax Return as being allocable to Seller
pursuant to Section 3(c) hereof, and (ii) any payments made by the Company on or
prior to the Closing Date, and by Seller and its Tax Affiliates at any time, in
respect of such Taxes (whether as estimated Taxes or otherwise).

                                      -10-
<PAGE>
 
     (b) This Section 10(b) shall govern the settlement as between Seller, Buyer
and the Company of all Straddle Period Tax allocations for Taxes that are not
required to be reported on a Straddle Period Return (e.g., Taxes which are
assessed without the filing of a Tax Return).  With respect to each such Tax
subject to allocation pursuant to Section 3(b) hereof, Buyer will, at least
thirty (30) days prior to the final due date of such Tax, provide to Seller (i)
a copy of the Tax assessment or other supporting schedules and workpapers and
(ii) a statement (including supporting schedules and workpapers) certifying the
amount of Tax that is allocable to Seller pursuant to Section 3(b) hereof
reduced by any payments made by the Company on or prior to the Closing Date, and
by Seller and its Tax Affiliates at any time, in respect of such Taxes (whether
as estimated Taxes or otherwise) (the "Statement").  Seller and its authorized
representatives will have the right to review the Statement for ten (10) days
following Seller's receipt of the Statement (the "10-Day Review Period").  If
Seller disagrees with the allocation in the Statement, Seller will notify Buyer
in writing of such disagreement prior to close of the 10-Day Review Period, and
Seller and Buyer will consult and attempt to resolve in good faith the
disagreement.  In the event Seller and Buyer are unable to resolve the
disagreement within ten (10) days following the end of the 10-Day Review Period,
Seller and Buyer will jointly request the Accountant to resolve the disagreement
pursuant to Section 16.  Not later than five (5) days after the later of (i) the
end of the 10-Day Review Period, or (ii) if there is a disagreement, the date
notice of the resolution of the disagreement by the Accountant is provided to
Buyer and Seller, Seller will pay to Buyer or Buyer will pay to Seller, as the
case may be, an amount equal to the difference between (i) the Taxes shown on
the Statement or in such notice (as the case may be) as being allocable to
Seller pursuant to Section 3(b) hereof, and (ii) any payments made by the
Company on or prior to the Closing Date, and by Seller and its Tax Affiliates at
any time, in respect of such Taxes (whether as estimated Taxes or otherwise).

     (c) Nothing contained in Section 10(a) or 10(b) shall be deemed to limit
the rights of the Company, Buyer or their Tax Affiliates to obtain
indemnification from Seller with respect to Chilean Income Taxes or other Taxes,
including, without limitation, their right to indemnification under Section 2
hereof.

     11.  Cooperation; Access to Information; Tax Records.
          ----------------------------------------------- 

     (a) Buyer, Seller and the Company will cooperate with each other with
respect to, and will make available to each other such Tax data and other
information relating to the Company as may be reasonably required for, (i) the
preparation by Buyer or Seller of any Tax Returns required to be prepared by
Buyer or Seller under this Agreement, (ii) determining the liability for and
amount of any Taxes due or the right to and amount of any refund of Taxes, (iii)
examinations or documentation of Tax Returns and Tax filing positions, and (iv)
any administrative or judicial proceeding in respect of Taxes assessed or
proposed to be assessed.  

                                      -11-
<PAGE>
 
Such cooperation shall include making all information and documents in their
possession related to the Company available to the other as provided in Section
11(b) hereof. Seller and Buyer shall also make available to the other, as
reasonably requested and available, personnel (including officers, directors,
employees and agents of Seller and Buyer and their Subsidiaries) responsible for
preparing, maintaining and interpreting information and documents relevant to
Taxes, and personnel reasonably required as witnesses or for purposes of
providing information or documents in connection with any administrative or
judicial proceedings relating to Taxes. Any information or documents provided
under this Section 11, shall be kept confidential by the party receiving the
information or documents, except as may otherwise be necessary in connection
with the filing of Tax Returns or in connection with any administrative or
judicial proceedings relating to Taxes. If requested by Seller, Buyer will
provide Seller, within ninety (90) days after the Closing Date, a completed tax
compliance manual (in a form prepared based on the Seller's and Company's past
practices) and Seller shall, if requested by Buyer, provide the Buyer, Company
and its Tax Affiliates with assistance in the preparation of such documentation,
data and other information necessary to meet such requirements (it being
mutually understood that such documentation, data and other information is
necessary in order for Seller and Buyer to satisfy their obligations to file Tax
Returns as provided in Section 9). In each case, the party requesting the
cooperation described herein shall reimburse the cooperating party for any
reasonable out-of-pocket expenses incurred in providing such cooperation.

     (b) Seller, Buyer, the Company and their respective Tax Affiliates shall
make available to each other, at such other's expenses, for inspection and
copying during normal business hours upon reasonable notice all Tax records in
their possession relating to the Company to the extent reasonably required by
the other party in connection with the preparation of Tax returns, audits,
litigation, or the resolution of items under this Agreement.  Seller, Buyer and
their respective Tax Affiliates shall preserve and keep such Tax records in
their possession until the expiration of any applicable statutes of limitation
and as otherwise required by law, but in any event for a period not less than
eight (8) years after the Closing.  Notwithstanding the foregoing, a party or
its Tax Affiliates may dispose of records sooner upon ninety (90) days prior
notice to the other party.  Such notice shall include a list of the records to
be disposed of describing in reasonable detail each file, book or other record
accumulation being disposed.  The notified party shall have the opportunity, at
its cost and expense, to copy or remove, within such ninety (90) day period, all
or any part of such Tax records.  For purposes of this Section 11, Tax records
include Tax Returns, journal vouchers, cash vouchers, general ledgers, material
contracts, return workpapers, and any other records pertaining to or used in the
preparation of Tax Returns (including those books and records required to be
maintained and made available pursuant to Section 8.2 of the Stock Purchase and
Sale Agreement).

     12.  Audits.
          ------ 
     (a) Buyer will promptly notify Seller in writing upon receipt by Buyer, the
Company, or their Tax Affiliates of notice of any pending Tax audits of or
written assessments against the Company, Buyer, or any of their Tax Affiliates
(i) relating to any taxable period of the Company ending on, prior to or
including the Closing Date, or (ii) that likely will affect the determination of
Taxes for which Seller is or may be obligated to indemnify Buyer pursuant to
this Agreement.  The notice required under this Section 12(a) is referred to in
this Agreement as the "Audit Notification."

     (b) Subject to Section 12(c) hereof, Seller will have the right, at its
election, (i) to represent the Company and to exclusively control the handling
of any Tax audit or assessment referred to in Section 12(a) hereof, including in
any administrative or court proceeding relating thereto, (ii) to employ counsel
of its choice at its expense and to control the conduct of such audit,
assessment, or proceeding, including settlement or other disposition thereof and
(iii) to settle the contest of any Tax or agree to an adjustment to any Tax
referred to in Section 12(a) (the rights under (i), (ii) and (iii) are referred
to in this Agreement collectively as the "Representation Right"); provided,
                                                                  -------- 
however, that the Representation Right will apply only to any issues or items
- -------                                                                      
(x) relating to any taxable period of the Company ending on, prior to or
including the Closing Date, or (y) that may affect the determination of Taxes
for which Seller is or may be obligated to indemnify the Company, Buyer, or
their Tax Affiliates pursuant to this Agreement.  As reasonably necessary, Buyer
will fully cooperate, and will cause the Company and its Tax Affiliates to fully
cooperate, at Seller's expense with Seller and its counsel in the defense
against or compromise of any claim in any said audit, assessment, or proceeding,
such cooperation to include (but not be limited to) the grant of any necessary
powers of attorney.  Notwithstanding the preceding sentence, Seller shall
neither consent nor agree to the settlement of any dispute regarding Taxes
(other than Taxes for which Seller is obligated to indemnify the Company, Buyer
or any of their Tax Affiliates) which settlement may have a material adverse
impact on the Company and its Tax Affiliates without the prior written consent
of the Buyer, which consent shall not be unreasonably withheld or delayed.

     (c) Seller shall be entitled to exercise the Representation Right, only if,
within a reasonable period following the receipt of the Audit Notification,
Seller shall have (i) notified Buyer in writing that Seller intends to exercise
the Representation Right, and (ii) delivered to Buyer a written statement
acknowledging Seller's obligation to indemnify the Company, Buyer, or their Tax
Affiliates in accordance with the terms of this Agreement with respect to the
Taxes as to which Seller exercises the Representation Right.

                                      -13-
<PAGE>
 
     (d) Buyer's personnel shall have the right to participate in any
administrative or judicial proceedings for which the Seller exercises its
Representation Right (including assisting with field audits, administrative
appeals, and subsequent litigation) in so far as they relate to the Company, and
such participation shall be reflected by the grant of appropriate powers of
attorney.

     (e) Buyer shall have exclusive control of all administrative and judicial
proceedings related to the Company's Taxes other than those described in Section
12(a).

     (f) For so long as the Seller is exercising its Representation Right, the
Seller shall not be required to indemnify the Buyer pursuant to Section 14
hereof until there occurs a Final Determination of the liability of the Company,
the Buyer or its Tax Affiliates for the Tax.

     13.  Treatment of Indemnification. Unless otherwise required by law, on
          ----------------------------
their Tax Returns, Seller and Buyer will (and will cause their Tax Affiliates
to) treat any payment made or received under this Agreement, or the Stock
Purchase and Sale Agreement, as an adjustment to the Purchase Price.

     14.  Indemnification.
          --------------- 
     (a) If either Buyer or Seller (the "Indemnified Party") determines that it
or any of its Tax Affiliates is or may be entitled to indemnification by the
other party (the "Indemnifying Party") under this Agreement as a result of: (i)
the allocations of responsibility for Taxes set forth in Sections 2 through 4 or
(ii) the Seller's breach of a representation or warranty contained in Section
18, the Indemnified Party will promptly deliver to the Indemnifying Party a
written notice and demand therefor (the "Notice") specifying the basis for its
claim for indemnification, the nature of the claim, and, if known, the amount
for which the Indemnified Party reasonably believes it or any of its Tax
Affiliates is entitled to be indemnified.  The Notice must be received by the
Indemnifying Party no later than thirty (30) days before the expiration of the
applicable Tax statute of limitations; provided, however, that if the
Indemnified Party does not receive notice from the applicable governmental
taxing authority ("Government Notice") that an item exists that could give rise
to a claim for indemnification hereunder more than thirty (30) days before the
expiration of the applicable Tax statute of limitations, then the Notice must be
received by the Indemnifying Party immediately after the Indemnified Party
receives the Government Notice.  Unless the Indemnifying Party objects to the
claim for indemnification (in the manner set forth in Section 14(b) hereof), and
subject to Section 12(f), the Indemnifying Party will pay the Indemnified Party
the amount set forth in the Notice, in cash or other immediately available
funds, within thirty (30) days after receipt of the Notice; provided, however,
that if the amount for which the Indemnified Party reasonably believes it is
entitled to be indemnified 

                                      -14-
<PAGE>
 
is not known at the time of the Notice, the Indemnified Party will deliver to
the Indemnifying Party a further notice specifying such amount as soon as
reasonably practicable after such amount is known and payment will then be made
as set forth above.

     (b) The Indemnifying Party may object to the claim for indemnification (or
the amount thereof) set forth in any Notice by giving the Indemnified Party,
within thirty (30) days following receipt of such Notice, written notice setting
forth the Indemnifying Party's grounds for so objecting (the "Objection
Notice").  If the Indemnifying Party does not give the Indemnified Party the
Objection Notice within such thirty (30)-day period, the Indemnifying Party may
exercise any and all of its rights under applicable law to collect such amount.

     (c) If Buyer and Seller are unable to settle any dispute regarding a claim
for indemnification within thirty (30) days after receipt of the Objection
Notice, Buyer and Seller will, in accordance with Section 16, jointly request
the Accountant to resolve the dispute as promptly as possible.

     (d) Failure by the Indemnified Party to promptly deliver to the
Indemnifying Party a Notice in accordance with Section 14(a) hereof will not
relieve the Indemnifying Party of any of its obligations under this Agreement
except to the extent the Indemnifying Party is prejudiced by such failure.

     (e) The indemnification provisions of this Section 14 shall be the
exclusive remedy following the Closing for any breaches or alleged breaches of
any representation, warranty or other provision of this Agreement and for the
allocation of Taxes pursuant to this Agreement.  Each of the parties hereto, on
behalf of itself and its officers, directors, employees, shareholders, partners,
affiliates, agents or representatives (collectively, such party's
"Representatives") agrees not to bring any actions or proceedings, at law,
equity or otherwise, against any other party or its Representatives, in respect
of any breaches or alleged breaches of any representation, warranty or other
provision of this Agreement, except pursuant to and subject to the express
provisions of this Section 14.

     15.  Termination of Existing Tax Sharing Agreements. Except as set forth on
          ----------------------------------------------
Schedule 15 hereto, as of the close of the Closing Date, any Tax sharing
agreement or arrangement that exists or may exist between the Company and Seller
or its Affiliates will terminate, and any obligations to make payments under any
such agreement or arrangement will be canceled.

     16.  Resolution of Disputes. If Seller and Buyer fail to mutually agree on
          ----------------------
the resolution of any of the matters in this Agreement which require the
agreement of the parties, then such matter shall be referred to the Accountant
for a binding determination. Seller and Buyer shall deliver to the Accountant
copies of any schedules or documentation which may be reasonably required by the
Accountant
                                      -15-
<PAGE>
 
to make its determination. Seller and Buyer shall be entitled to make
presentations to the Accountant in connection therewith. Seller and Buyer shall
use all reasonable efforts to cause the Accountant to promptly complete such
determination. The determination of the Accountant shall be final and binding on
all parties. The costs incurred in retaining the Accountant to make a
determination shall be shared equally by Seller and Buyer.

     17.  Payment. All currency amounts required to be paid to a party under
          -------
this Agreement shall be paid in United States of America Dollars. If a party
(the "Payor") fails to make a payment due and owing under this Agreement to the
other party or any of its Tax Affiliates (the "Payee") reasonably within five
business days after the parties hereto agree (or there is a binding
determination) that such payment is due and owing, the Payor will pay to the
Payee interest on such payment from and including the date the parties reach

     18.  Seller's Representations and Warranties.  Cyprus Amax and Specialty,
          ---------------------------------------                             
jointly and severally, hereby represent and warrant to Buyer as set forth below.
Disclosure of any items not otherwise required to be disclosed shall not create
any inference of materiality.

     (a) Except as set forth on Schedule 18(a), all required Income Tax Returns
with respect to the Company and the Company's Tax Affiliates (including the
Chilean Partnership) have been duly filed and Seller will cause to be filed all
required Income Tax Returns that are due to be filed on or before the Closing
Date on a timely basis (or will have filed an accurate/complete appropriate
application for extension of time to file).  All such Tax Returns were true,
correct and complete in all material respects when filed.  Neither the Company
nor any of the Company's Tax Affiliates is delinquent in the payment of any Tax
or estimated Tax payable by or on behalf of the Company or any of the Company's
Tax Affiliates for any Taxes for any Tax periods covered by the Tax Returns
referred to in the preceding sentence (whether or not shown on such Tax Returns)
(other than any Income Taxes the amount or validity of which are being contested
in good faith by appropriate proceedings).

     (b) The Company has delivered to Buyer true copies of the Company's and its
Subsidiaries' federal, state and foreign Income Tax Returns for the tax years
1994, 1995 and 1996.

     (c) Except as set forth on Schedule 18(c), the Company is not a party to,
bound by, or subject to, any obligation under any Tax sharing, Tax
indemnification or similar agreement or has any liability for the Taxes of any
other Person as a transferee, successor or otherwise.

                                      -16-

     (d) The Company has not filed a consent pursuant to Section 341(f) of the
Code or agreed to have Section 341(f)(2) of the Code apply to any disposition of
a subsection (f) asset (as such term is defined in Section 341(f)(4) of the
Code) owned by it.

     (e) No property owned by the Company is property that the Buyer, or the
Company or any of their Affiliates is or will be required to treat as being
owned by another person pursuant to the provisions of Section 168(f)(8) of the
Internal Revenue Code of 1954, as amended and in effect immediately prior to the
enactment of the Tax Reform Act of 1986, is tax-exempt use property within the
meaning of Section 168(h)(1) of the Code or tax-exempt bond financed property
within the meaning of Section 168(g) of the Code.

     (f) Except as set forth in Schedule 18(f), none of the Company nor any
Subsidiary of the Company has given or been requested to give waivers or
extensions (or is or would be subject to a waiver or extension given by any
other Person) of any statute of limitations relating to the payment of Taxes of
any of them.

     (g) All Taxes that the Company or any Subsidiary of the Company is or was
required by Law to withhold or collect have been duly withheld and collected
and, to the extent required, have been paid to the proper Governmental Authority
or taxing authority.

     (h) The Seller is not a foreign person subject to withholding under Section
1445 of the Code and the regulations promulgated thereunder, and, at the
Closing, Seller shall deliver to Buyer a certificate to that effect (a "FIRPTA
                                                                        ------
Certificate").
- -----------   

     (i) There is no agreement, plan, arrangement or other contract covering any
employee or independent contractor of the Company or any of its Tax Affiliates
that could give rise to the payment of any amount that could not be deductible
pursuant to Section 280G of the Code.

     (j) There are no pending, proposed, or, to the Knowledge of Seller,
threatened, audits, judicial proceedings, assessments or deficiencies with
respect to Taxes of the Company or any of its Subsidiaries.  There is no
pending, proposed, or, to the Knowledge of Seller, threatened, claim by any
Governmental Authority in any jurisdiction in which any of the Seller, the
Company of any of its Tax Affiliates do not pay Taxes or file Tax Returns that
any such Person is required to pay Taxes or file Tax Returns.

     (k) Except as set forth in Schedule 18(k), neither the Company nor any of
its Subsidiaries has agreed or is required to make any adjustment under Section
481(a) of the Code or any comparable provision of state, local or foreign law.

                                      -17-
<PAGE>
 
     (l) No liens for Taxes exist with respect to the assets, income or
operations of any of the Seller, the Company or any of its Subsidiaries other
than any lien for Taxes which are being contested in good faith and by
appropriate proceedings.

     19.  Section 338(h)(10) Election.

     (a) Buyer (or one of its Tax Affiliates) and Seller will join in making,
and will take (and will cause its respective Tax Affiliates to take) any and all
action necessary to effect a timely election with respect to the sale of the
stock of the Company under Section 338(h)(10) of the Code (and the Treasury
Regulations and administrative pronouncements thereunder) and any comparable
provision of state or local Tax law (including any state or local tax law which
treats a Section 338(h)(10) Election as a Section 338 Election) (collectively a
"Section 338(h)(10) Election").  Seller and Buyer acknowledge that for Federal
Income Tax purposes (and for State Income Tax purposes in those states whose
Income Tax provisions follow the Federal Income Tax Treatment), the sale of the
stock of the Company combined with the Section 338(h)(10) Election will be
treated as a sale of assets by the Company to Buyer followed by a complete
liquidation of the Company into Seller.  Buyer and Seller will report (and will
cause their respective Tax Affiliates to report) any transactions that occur
under the Stock Purchase and Sale Agreement or hereunder consistent with the
Section 338(h)(10) Election, and will take no position (nor allow their
respective Tax Affiliates to take a position) contrary thereto.  Buyer and its
Tax Affiliates agree to make an election under Section 338 with respect to the
Chilean Partnership and its shareholder.

        (b)  Seller and the Buyer shall each provide to the other all necessary
information to permit the Section 338(h)(10) Election to be made.

        (c)  Within ninety (90) days after the Closing Date, Buyer shall:

             i.  determine, based upon the principles contained in the relevant
                 Treasury regulations, the modified adjusted deemed sales price
                 ("MADSP") for the assets of the Company (within the meaning of
                 Treasury regulation (S)1.338(h)(10)-1(f)); and

             ii. determine, based upon the principles contained in the relevant
                 Treasury regulations, the proper allocation of such MADSP among
                 the assets of the Company in accordance with Treasury
                 regulation (S)1.338(b)-2T (together (i) and (ii) are the
                 "Allocations").

In making the determinations under this subparagraph (c), Buyer shall consult in
good faith with the Seller and keep the Seller informed as to the methodology
and status of such determinations.

                                      -18-
<PAGE>
 
     (d) Buyer shall prepare all forms (including, without limitation, Internal
Revenue Service Form 8023) and schedules (collectively, the "Forms") necessary
to effect the Section 338(h)(10) Election and will deliver a completed copy of
any such Forms to Seller for its review within sixty (60) days after the date
provided in Section 19(c).  At the Closing, Seller and Buyer shall both execute
and deliver completed pro-forma Forms 8023.

     (e) Seller shall have the right within thirty (30) days following the
delivery of the Allocations to object in writing to the Allocations specifying
in reasonable detail the basis for such objection(s).  Seller shall be deemed to
have agreed with the Allocations, except as specifically objected to in such
notice.  If Seller does so object, Seller and Buyer shall cooperate with each
other to attempt to reach a mutual agreement thereon, or, failing such agreement
within twenty (20) days, Seller and Buyer will, in accordance with Section 16
thereof, jointly request the Accountant to resolve the dispute as promptly as
possible.

     (f) Seller shall calculate the gain or loss, if any, resulting from the
Section 338(h)(10) Election in a manner consistent with the determination of
MADSP and the Allocations and shall not take any position inconsistent with the
Section 338(h)(10) Election, the MADSP or the Allocations in connection with any
Tax Return or otherwise.

     (g) Buyer shall determine its tax basis for the assets of the Company in a
manner consistent with the determination of MADSP and the Allocations and shall
not take any position inconsistent with the Section 338(h)(10) Election, the
MADSP or the Allocations in any Tax Return or otherwise.

     (h) Buyer covenants that, during the period beginning immediately after the
Closing and ending at the close of the Closing Date, the Company will not engage
in any transaction that is not in the ordinary course of business of the
Company.

shall survive the Closing and be enforceable for a period of ninety (90) days
after the expiration of the applicable statute of limitations with respect to
the relevant item of Tax, but shall thereafter be of no force or effect, except
as they relate to a Notice filed under Section 14.  All covenants and agreements
contained in this Agreement shall survive the Closing in accordance with their
terms.

     21.  Amendments.  Any amendment, supplement, variation, alteration or
          ----------

          ---------
insist upon performance of any of the terms, covenants or conditions of this
Agreement, to exercise any right or privilege in this Agreement conferred, or to
waive any breach of any of the terms, covenants or conditions of this Agreement,
shall not be construed as a subsequent waiver of any such terms, covenants,
conditions, rights or privileges, but the same shall continue and remain in full
force and effect as if no such forbearance or waiver had occurred. No waiver
shall be effective unless it is in writing and signed by an authorized
representative of the waiving party.

     25.  No Double Recovery. No provision of this Agreement shall be construed
          ------------------
to provide an indemnity or other recovery for any Taxes, costs, damages, or
other amounts for which the damaged person has been fully compensated under any
other provision of this Agreement or under any other agreement or action at law
or equity.

     26.  Severability.  Any provision of this Agreement which is prohibited or
          ------------                                                         
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
other jurisdiction shall not invalidate or render unenforceable such provision
in any other jurisdiction.  To the extent permitted by applicable law, each
party hereby waives any law which renders any provision hereof prohibited or
unenforceable in any respect.

     27.  Counterparts.  This Agreement may be executed in counterparts, each of
          ------------                                                          
which shall be deemed to be an original, and all such counterparts shall be
deemed to constitute one and the same instrument.

                    CYPRUS AMAX MINERALS COMPLETES SALE OF
                        LITHIUM UNIT TO CHEMETALL GmbH

     DENVER (October 13, 1998)  Cyprus Amax Minerals Company (NYSE:CYM) today
announced it has completed the sale of its Cyprus Foote Mineral Company lithium
subsidiary to an affiliate of Chemetall GmbH, a specialty chemicals unit of
Metallgesellschaft AG.

     Cyprus Amax received $305 million in cash in the transaction and expects to
report a pre-tax gain of approximately $150 million from the sale.  This should
result in an after-tax gain of slightly over $100 million in the fourth quarter.
However, as a result of the sale of assets earlier in the year, only a nominal
amount of Federal Income Taxes are expected to be paid.  Proceeds from the sale
will be used for general corporate purposes, including debt reduction, the share
buyback program and to strengthen Cyprus Amax's financial position and core
mining businesses.

     Merrill Lynch served as advisor to Cyprus Amax for the sale.

     Cyprus Amax Minerals Company, headquartered in Englewood, Colorado, is a
leading producer of copper and coal, the world's largest producer of molybdenum,
and holds a 31% interest in Kinross Gold.  Cyprus Amax is exploring for minerals
worldwide.

     Actual results may vary materially from any forward-looking statement the
Company makes.  Refer to the Cautionary Statement and Risk Factors contained in
the Company's most recent Form 10-K.
