1.    GENERAL

     Century Aluminum Company ("Century" or the "Company") is a holding company
whose principal subsidiary is Century Aluminum of West Virginia, Inc. ("Century
of West Virginia"), which operates a primary aluminum reduction facility and an
aluminum fabrication facility in Ravenswood, West Virginia. Century of West
Virginia, through its wholly-owned subsidiary Berkeley Aluminum, Inc.
("Berkeley"), holds a 26.67% interest in a partnership which operates a primary
aluminum reduction facility in Mt. Holly, South Carolina ("MHAC") and a 26.67%
undivided interest in the property, plant and equipment comprising MHAC.

     Glencore AG and Vialco Holdings Ltd., which are wholly-owned subsidiaries
of Glencore International AG (together with its subsidiaries, the "Glencore
Group") own 7,925,000 common shares, or 39.6% of the common shares outstanding
of the Company. Century and the Glencore Group enter into various transactions
such as the purchase and sale of primary aluminum, scrap aluminum, alumina and
metals risk management.

     The accompanying unaudited interim consolidated financial statements of the
Company should be read in conjunction with the audited consolidated financial
statements for the year ended December 31, 1997. In management's opinion, the
unaudited interim consolidated financial statements reflect all adjustments,
which are of a normal and recurring nature, which are necessary for a fair
presentation, in all material respects, of financial results for the interim
periods presented. Operating results for the first six months of 1998 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 1998. Certain reclassifications of prior-period information were
made to conform to the current presentation.

2.    INVENTORIES

     Inventories consist of the following:

</TABLE>

     At June 30, 1998 and December 31, 1997, approximately 89% of inventories
were valued at the lower of last-in, first-out ("LIFO") cost or market. The
excess of the LIFO cost (or market, if lower) of inventory over the first-in,
first-out ("FIFO") cost was approximately $20,273 and $16,670 at June 30, 1998
and December 31, 1997, respectively.

3.    BANK REVOLVING CREDIT FACILITY

     On January 30, 1996, Century of West Virginia and Berkeley entered into a
three-year bank revolving credit facility ("Facility") with BankAmerica Business
Credit, Inc. ("Bank of America"). The Facility provides for a revolving credit
facility that consists of borrowings and letters of credit up to $150,000 in the
aggregate. On May 11, 1998, the Company and Bank of America agreed to amend and
extend the Facility to January 30, 2001.

     Subject to certain limitations, the Company may select base rate or LIBOR
loans. Under the terms of the agreement, through January 31, 1999, the interest
rate is (i) for base rate loans, 0.5% in excess of the base rate, which is the
rate publicly announced from time to time by Bank of America as its reference
rate, or (ii) for LIBOR loans, 1.75% in excess of the one-, two-, three- or
six-month LIBOR as quoted from time to time by Bank of America. After January
31, 1999, the interest rate margins on base rate loans will range from 0.25% to
0.75% and on LIBOR loans from 1.5% to 2.0% based on the attainment of certain
financial ratios. The interest rate on the borrowings under the Facility was
8.18% on June 30, 1998. Borrowings of $60,423 as of June 30, 1998 are
collateralized by Century of West Virginia's and Berkeley's inventory and
receivables and are guaranteed by the Company.

4.    CONTINGENCIES AND COMMITMENTS

Environmental Contingencies

     The Company's operations are subject to various environmental laws and
regulations. The Company has spent, and expects to spend in the future,
significant amounts for compliance with those laws and regulations.

     Pursuant to an order issued in September 1994 under Section 3008(h) (the
"3008(h) order") of the Resource Conservation and Recovery Act ("RCRA"), Century
of West Virginia is performing remediation measures at a former oil pond area
and in connection with cyanide contamination in the groundwater, and is
conducting a RCRA facility investigation ("RFI") and a corrective measures study
("CMS") to evaluate and develop corrective alternatives for any areas that have
contamination exceeding certain levels. The Company completed initial sampling
and analysis and submitted its initial findings to the Environmental Protection
Agency ("EPA"). The EPA has requested that the Company perform additional field
work and testing. As a result, the Company anticipates that the RFI will not be
completed before late 1998. Once the RFI and CMS are complete, the EPA will
assess the need for clean-up, and if any clean-up is required, a subsequent
order will be issued. At this time, the Company is unable to determine the
extent of clean-up measures, if any, that may be required. However, the Company
is aware of some environmental contamination at Century of West Virginia, and it
is likely that clean-up activities will be required in at least some areas of
the facility. The Company believes a significant portion of this contamination
is attributable to the operations of a prior owner and will be the financial
responsibility of that owner, as discussed below.

                      PERIODS ENDED JUNE 30, 1998 AND 1997


     Prior to the Company's acquisition of the Century of West Virginia
facility, Kaiser Aluminum & Chemical Corporation ("Kaiser") owned and operated
the facility for approximately thirty years. Many of the conditions which the
Company is required to investigate under the 3008(h) order arise out of
activities which occurred during Kaiser's ownership and operation, and with
respect to those conditions, Kaiser will be responsible for the costs of the RFI
and required cleanup under the terms of the purchase agreement ("Kaiser Purchase
Agreement"). In addition, Kaiser retained title to certain land within the
Century of West Virginia premises and retains full responsibility for those
areas. Under current environmental laws and regulations, the Company may be
required to remediate any contamination discovered during or after completion of
the RFI, which contamination was discharged from areas which Kaiser previously
owned or operated, or for which Kaiser has retained ownership or responsibility.
However, if such remediation is required, the Company believes that Kaiser will
be liable for some or all of the costs thereof pursuant to the Kaiser Purchase
Agreement.

     The Company is aware of two areas of contamination in the soil and
groundwater at its previously-owned Vialco facility. At the first of these
areas, the Company has removed quantities of contaminated soils and has
transported and disposed of such soils in approved facilities. In addition, it
has begun a bioremediation program which it believes will fulfill the remaining
legal requirements with respect to such soils. In the second area, the Company
believes that a substantial amount of the contamination originated from an
adjacent refinery owned by Hess Oil Virgin Islands, Inc. ("HOVIC"). The Company
further believes that the vast majority of any contamination which did not
originate from HOVIC was caused by releases on the property which predated
Vialco's ownership and will not be the legal responsibility of Vialco. Pursuant
to the Acquisition Agreement by which Vialco sold the premises to St. Croix
Alumina, L.L.C., a subsidiary of Alcoa Alumina and Chemicals L.L.S. ("St.
Croix"), Vialco retained liability for environmental conditions existing at the
time of the sale only to the extent such conditions arose from operation of the
facility by Vialco. In addition, indemnification arises only if the conditions
require remediation or give rise to claims under the laws in effect at the time
of sale. Finally, St. Croix may not request indemnity from Vialco until St.
Croix has spent $300 on such environmental conditions and Vialco's indemnity is
capped at $18,000. Management of the Company does not believe that the retained
liability, if any, will have a material adverse effect on the Company's
financial condition, results of operations or liquidity.

     It is the Company's policy to accrue for costs associated with
environmental assessments and remedial efforts when it becomes probable that a
liability has been incurred and the costs can be reasonably estimated. The
aggregate environmental related accrued liabilities were $1,374 and $1,052 at
June 30, 1998 and December 31, 1997, respectively. All accruals have been
recorded without giving effect to any possible future insurance or Kaiser
indemnity proceeds. With respect to ongoing environmental compliance costs,
including maintenance and monitoring, such costs are expensed as incurred.

                      PERIODS ENDED JUNE 30, 1998 AND 1997

     Because of the issues and uncertainties described above, and the Company's
inability to predict the requirements of future environmental laws, there can be
no assurance that future capital expenditures and costs for environmental
compliance will not have a material adverse effect on the Company's future
financial condition, results of operations or liquidity. Based upon all
available information and after consultation with counsel, management does not
believe that the outcome of these environmental matters will have a material
adverse effect on the Company's financial condition, results of operations or
liquidity.

Legal Contingencies

     Century of West Virginia is a named defendant (along with other companies)
in approximately 4,095 civil actions brought by individuals seeking to recover
significant compensatory and/or punitive damages in connection with various
asbestos-related diseases. However, counsel for the plaintiffs have represented
that Century of West Virginia will be dismissed from 2,412 cases because the
plaintiffs in these cases had no contact with the Century of West Virginia
facility. All of the remaining 1,683 plaintiffs have been employees of
independent contractors who claim to have been exposed to asbestos in the course
of performing services at various facilities, including the Century of West
Virginia facility. The cases are typically resolved based upon factual
determinations as to the facilities at which the plaintiffs worked, the periods
of time during which work was performed, the type of work performed and the
conditions in which work was performed. If the plaintiffs' work was performed
during the period when Kaiser owned the Century of West Virginia facility,
Kaiser has retained responsibility, pursuant to the terms of the Kaiser Purchase
Agreement, for defense and indemnity. If a plaintiff is shown to have worked at
the Century of West Virginia facility after the time Century of West Virginia
purchased the facility from Kaiser, Kaiser assumes the defense and liability,
subject to a reservation of rights against Century of West Virginia. The Company
believes it is unlikely that existing or potential plaintiffs were exposed to
asbestos at the Century of West Virginia facility after Century of West Virginia
purchased the facility from Kaiser, although nineteen plaintiffs have claimed
they were exposed during this period of time. Claims with nine of these
plaintiffs have been settled for nominal amounts or dismissed. Therefore, while
the impact of the asbestos proceedings is impossible to predict, the Company
believes that the ultimate resolution will not have a material adverse effect on
the Company's financial condition, results of operations or liquidity.

     The Company has pending against it or may be subject to various other
lawsuits, claims and proceedings related primarily to employment, commercial,
environmental and safety and health matters. Although it is not presently
possible to determine the outcome of these matters, management believes their
ultimate disposition will not have a material adverse effect on the Company's
financial condition, results of operations or liquidity.

     Commitments

     The Company and a public utility have a fixed price power supply agreement,
covering the period from July 1, 1996 through July 31, 2003.

     On January 23, 1996, the Company and the Pension Benefit Guaranty
Corporation ("PBGC") entered into an agreement (the "PBGC Agreement") which
provided that the Company make scheduled cash contributions to its pension plan
for hourly employees in 1996, 1997, 1998 and 1999. The Company made its
scheduled contributions in 1996 and 1997 and estimates that its scheduled
contributions in each of the remaining years will be $7,000 above the minimum
required contributions under Section 412 of the Internal Revenue Code. The
Company has granted the PBGC a first priority security interest in (i) the
property, plant and equipment at its Century of West Virginia facility and (ii)
all of the outstanding shares of Berkeley. In addition, Century must grant the
PBGC a first priority security interest in the first $50,000 of the property,
plant and equipment of any business or businesses that the Company acquires. The
Company, in its discretion, may, however, substitute Berkeley's undivided
interest in the Mt. Holly Facility in lieu of any such after-acquired property,
plant and equipment as well as the shares of Berkeley.

     The Company has provided a $27,500 letter of credit to ensure its
performance under the Owners Agreement governing MHAC. Pursuant to the amended
Owners Agreement, the Company's obligation to maintain the letter of credit was
terminated during the quarter ended June 30, 1998.

5.    FIXED-PRICE COMMITMENTS AND FORWARD CONTRACTS

     The Company had fixed price commitments to sell 299.1 million pounds and
298.4 million pounds of primary and scrap aluminum and aluminum sheet and plate
products at June 30, 1998 and 1997, respectively. In addition, the Company had
fixed price commitments to purchase 115.6 million pounds and 67.8 million pounds
of aluminum and alloy raw materials at June 30, 1998 and 1997, respectively.

     The Company is in a net long metal position and, therefore, is exposed to
the influence of the commodity price of primary aluminum on the selling prices
for its products. In order to reduce this exposure, the Company has entered into
forward sales contracts for primary aluminum that will be settled in cash. At
June 30, 1998, the Company had forward sales contracts with the Glencore Group
for 93.8 million pounds scheduled for settlement at various dates in 1998 and
1999.

     All gains and losses from forward contract activity are being reported
separately in the statements of operations. Unrealized gains or losses on the
forward primary aluminum contracts, realized gains or losses from the cash
settlement of the forward primary aluminum contracts, unrealized losses on fixed
price purchase and sale commitments and reversals of prior period unrealized
losses are reported as either gains or losses on forward contracts.

     The Company entered into a long-term supply agreement for 936 million
pounds of alumina annually, beginning January 1, 1996. The Company will pay a
fixed price for alumina with fixed annual price increases of approximately 2.5%
through 2001. Pricing for the years 2002 through 2006 will be subject to
agreement between the parties.

7.   SUBSEQUENT EVENT

     On August 7, 1998, the Company announced that Century and Glencore Group
have entered into an agreement with the state of Victoria in Australia to
acquire Aluminium Smelters of Victoria Pty ("Aluvic"), a wholly owned holding
company of the state. Aluvic's principal holding is a 25 percent direct interest
in a joint venture that owns the 345,000 metric-ton-per-year aluminum smelter at
Portland, in Victoria. The managing partner in the joint venture is Alcoa of
Australia Limited, which holds a 45 percent interest. Other members of this
venture, each with a 10 percent share, are China International Trust and
Investment Corporation, Eastern Aluminium and Marubeni.

     The Portland joint venture agreement stipulates that existing owners have
first right of refusal to acquire the share being sold by the state of Victoria.
The acquisition of the 25 percent interest in the Portland Smelter by
Century/Glencore Group joint venture, therefore, depends on existing owners
declining to purchase Aluvic's share. They must exercise their purchase rights
before August 24, 1998.

     The purchase price, subject to adjustment, is approximately $290 million.
Glencore Group and Century intend to finance a significant portion of the
purchase price with non-recourse project bonds. The Company intends to finance
any remaining requirements through direct borrowings.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

OVERVIEW

     The Company is an integrated manufacturer of primary aluminum and a broad
range of value-added and specialized flat-rolled sheet and plate aluminum
products. The aluminum industry is highly cyclical and the market price of
aluminum (which trades as a commodity) has been volatile from time to time. In
turn, prices of flat-rolled sheet and plate aluminum products have reflected
this volatility as well as fluctuations attributable to general and
industry-specific economic conditions. However, there is less price volatility
in the higher value-added products such as plate. The principal elements
comprising the Company's cost of goods sold are raw materials, energy and labor.
The major raw materials and energy sources used by the Company in its production
process are alumina, aluminum scrap, coal tar, pitch, petroleum coke, aluminum
fluoride and electricity.

     Selling by funds, consumer hesitation in anticipation of lower prices, and
economic uncertainty in Asian markets have influenced the cash price for primary
aluminum on the London Metals Exchange ("LME"). The average cash price per tonne
in the second quarter of 1998 was $1,363. This is a decline of $100 per tonne
from 1998's first quarter average of $1,463 and a decline of $221 per tonne from
1997's second quarter average of $1,584.

     Demand for flat rolled products in the United States in the second quarter
of 1998 was about level with demand in the second quarter of 1997, with the
transportation market showing strength and the building and construction market
benefiting from a comparatively mild winter.

RESULTS OF OPERATIONS

     The following table sets forth, for the three and six months ended June
30,1998 and 1997, the percentage relationship to net sales of certain items
included in the Company's condensed consolidated statements of operations.

(1) Does not include forward sales contracts without physical delivery.

Net Sales. Net sales during the three and six months ended June 30, 1998 were
$156.8 million and $333.2 million, a decrease of $34.7 million (or 18.1%) and
$49.9 million (or 13.0%) from comparable 1997 periods. The Company shipped 112.9
million and 234.7 million pounds of sheet and plate products in the three and
six months ended June 30, 1998 versus 147.5 million and 298.5 million pounds
shipped in the comparable 1997 periods. Most of the declines were in products
that have been de-emphasized as a result of the rolling operations restructuring
completed in 1997.

Lower sheet and plate volume had the effect of decreasing revenue by $36.3
million and $64.6 million during the comparable three and six months ended June
30, 1998 and 1997. The volume decline was partially offset by $9.6 million and
$25.0 million improvements in the mix and price of sheet and plate products sold
during the comparable 1998 and 1997 periods. Lower sales of primary products
reduced revenue by $8.0 million and $10.3 million during the comparable 1998 and
1997 periods.

Cost of Goods Sold. Cost of goods sold during the comparable three and six
months ended June 30, 1998 and 1997 decreased $35.0 million (or 19.4%) and $56.7
million (or 15.5%). Most of these declines in cost are attributable to the
reduced volumes, but the Company's cost of goods sold also benefited from the
influence of lower LME prices on its scrap aluminum inputs.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses decreased $1.3 million and $1.1 million during the
comparable three and six months ended June 30, 1998 and 1997. The decrease was
due principally to lower legal and credit related expenses.

Net Gains on Forward Contracts. Lower LME prices during the first six months of
1998 improved the market value of the Company's forward contracts. As a result,
the Company recorded net gains on forward contracts of $5.5 million and $6.5
million during the three and six 



                                       11
<PAGE>   14

months ended June 30, 1998. During comparable periods of 1997, the Company
recorded a net loss on forward contracts of $0.5 million and a net gain of $0.5
million.

Net Income. As a result of improved price realizations for sheet and plate
products, lower costs for scrap aluminum inputs and forward contract gains, net
income for the three and six months ended June 30, 1998 and 1997 increased $5.3
million and $9.4 million, respectively.

LIQUIDITY AND CAPITAL RESOURCES

     Working capital at June 30, 1998 and 1997 was $178.8 and $180.5 million,
respectively. The Company's liquidity requirements arise from working capital
needs, capital investments and debt service.

     The Company's statements of cash flows for the six months ended June 30,
1998 and 1997 are summarized below (dollars in thousands):

</TABLE>

     In the six months ended June 30, 1998, operating activities provided $22.1
million in net cash to the Company. Net income and a reduction in accounts
receivable, caused by changes in product/customer mix and trade accounts
receivable terms, added to the positive cash flow. This was partially offset by
payments for metal purchases, maintenance expenditures, and capital expenditures
that were accrued at December 31, 1997. Operating activities used $4.9 million
during the six months ended June 30 1997, due primarily to lower earnings and
the growth in the Company's accounts receivable as a result of increased sales
to third parties.

     Capital expenditures were $19.2 million in the first six months of 1998
compared to $11.0 million in the first six months of 1997. The Company used
these expenditures to purchase, modernize or upgrade production equipment,
maintain its facilities and comply with environmental regulations. A significant
portion of the expenditures in the first six months of 1998 were for the
expansion of the Company's heat-treated plate production capacity.

     Net cash used in financing activities in the first six months of 1998 was
$0.5 compared to net cash provided of $20.0 million in the first six months of
1997. The Company paid dividends in the first six months of 1998 and 1997 of
$1.0 and $2.0 million, or $0.05 and $0.10 per common share, respectively. The
cash provided by operations was sufficient to fund the Company's working capital
needs and investing activities in the first six months of 1998, so very little
additional borrowing was required.

     On January 30, 1996, Century of West Virginia and Berkeley entered into a
bank revolving credit facility ("Facility") with BankAmerica Business Credit,
Inc. ("Bank of America"). The Facility provides for a revolving credit facility
that consists of borrowings and letters of credit up 

                                       12
<PAGE>   15
to $150 million in the aggregate. On May 11, 1998, the Company and Bank of
America agreed to amend and extend the Facility to January 30, 2001. See Note 3
to the Consolidated Financial Statements.

     Pursuant to an agreement with the Pension Benefit Guaranty Corporation
("PBGC Agreement"), the Company is required to make scheduled contributions to
its pension plan for hourly employees with respect to 1998 and 1999. The Company
estimates that each of these scheduled contributions will be approximately $7.0
million above the minimum required contributions under Section 412 of the
Internal Revenue Code.

     The Company believes that cash flow from operations and funds available
under the Facility will be sufficient to fund its working capital requirements,
capital expenditures and debt service requirements in the near term and for the
foreseeable future.

METALS RISK MANAGEMENT

     Century produces primary aluminum products and manufactures aluminum sheet
and plate products and manages the risks of each accordingly. The Company is in
a net long metal position and, therefore, is exposed to the influence of the
commodity price of primary aluminum on the selling prices for its products. In
order to reduce this exposure, the Company has entered into forward sales
contracts for primary aluminum that will be settled in cash. At June 30, 1998,
the Company had forward sales contracts with the Glencore Group for 93.8 million
pounds of primary aluminum scheduled for settlement at various dates in 1998 and
1999. Based on market prices at June 30, 1998, these contracts could be settled
by the Glencore Group paying less than $0.1 million to the Company. The actual
settlement will be based on market prices on the respective settlement dates.

ENVIRONMENTAL EXPENDITURES AND OTHER CONTINGENCIES

     It is the Company's policy to accrue for costs associated with
environmental assessments and remedial efforts when it becomes probable that a
liability has been incurred and the cost can be reasonably estimated. The
aggregate environmental related accrued liabilities were $1.4 million at June
30, 1998 and $1.1 million at December 31, 1997, respectively. The Company has
incurred and, in the future, will continue to incur capital expenditures and
operating expenses for matters relating to environmental control, remediation,
monitoring and compliance. The Company believes that compliance with current
environmental laws and regulations is not likely to have a material adverse
effect on the Company's financial condition, results of operations or liquidity;
however, environmental laws and regulations have changed rapidly in recent years
and the Company may become subject to more stringent environmental laws and
regulations in the future. In addition, the Company may be required to conduct
remediation activities in the future pursuant to various orders issued by the
EPA and West Virginia Department of Environmental Protection. There can be no
assurance that compliance with more stringent environmental laws and regulations
that may be enacted in the future, or future remediation costs, would not have a
material adverse effect on the Company's financial condition, results of
operations or liquidity.

     The Company is a defendant in several actions relating to various aspects
of its business. While it is impossible to predict the ultimate disposition of
any litigation, the Company does not 

                                       13
<PAGE>   16
believe that any of these lawsuits, either individually or in the aggregate,
will have a material adverse effect on the Company's financial condition,
results of operations or liquidity. See Note 4 to Consolidated Financial
Statements.

OTHER

     The Company has reviewed its business systems to identify areas that could
be impacted by the "Year 2000" issue. The Year 2000 issue results from software
systems that only allow for the last two digits, rather than four digits, for
the applicable year. If left uncorrected, errors could occur in computations
that are dependent upon dates. As a result of its review, the Company has begun
a multi-phase project to significantly enhance its business systems.

     The Company will replace its existing financial systems and adopt
electronic tracking for its production processes and inventory. Initial work
will be completed in mid 1999 at a cost of approximately $8.0 million, with a
substantial portion of this amount capitalized. In addition, work is currently
being done to the business systems that will not be replaced to make them Year
2000 compliant.

     The Company is in the process of assessing Year 2000 compliance for its
operating systems and for key suppliers and service providers.

                           shall be effected if a Default or an Event of Default
                           shall have occurred and be continuing on the date
                           when such change would otherwise occur, it being
                           understood that on the Business Day immediately
                           succeeding the day on which such Default or Event of
                           Default is either waived or cured (assuming no other
                           Default or Event of Default shall be then pending),

                           of this Agreement, provided, however, that if any
                           Century Letter of Credit expires or is canceled
                           without a drawing occurring thereunder, then the
                           amount of the Capital Expenditure related to such
                           Century Letter of Credit shall be deemed to have been
                           reversed."

         a novation as to the Loan Agreement; instead, it is the express
         intention of the parties hereto to reaffirm the Obligations created
         under the Loan Agreement which are secured by the Collateral. The Loan
         Agreement, as amended hereby, and each of the other Loan Documents
         shall remain in full force and effect.

12.      Costs, Expenses and Indemnity. The Borrowers affirm and acknowledge
         that Section 15.7 and Section 15.11 of the Loan Agreement apply to this
         Amendment and the transactions and agreements and documents
         contemplated hereunder.

                            CONSENT OF THE GUARANTOR


         The undersigned, CENTURY ALUMINUM COMPANY, a Delaware corporation (the
"Guarantor"), (i) consents to and approves the execution and delivery of this
Amendment by the parties hereto, (ii) agrees that this Amendment does not and
shall not limit or diminish in any manner the obligations of the Guarantor under
that certain Guaranty dated as of January 30, 1996 (the "Guaranty"), executed by
the Guarantor and delivered to the Agent, or under any of the other documents
executed and delivered by the Guarantor in connection with the Guaranty, and
agrees that such obligations of the Guarantor would not be limited or diminished
in any manner even if the Guarantor had not executed this Amendment, (iii)
agrees that this Amendment shall not be construed as requiring the consent of
the Guarantor in any other circumstance, (iv) reaffirms its obligations under
the Guaranty and such other related documents, and (v) agrees that the Guaranty
and such other related documents remain in full force and effect and are hereby
ratified and confirmed. Without limiting the generality of the foregoing, the
Guarantor agrees to perform and comply with each of the covenants contained in
sections 9.9 through 9.28 of the Loan Agreement, as amended by this Amendment,
which by their terms refer to the Guarantor, and further agrees not to cause or
permit either Borrower to violate any of such covenants.

         The Guarantor further agrees that all terms, conditions and provisions
of the Loan Agreement relating to Letters of Credit (as defined in the Loan
Agreement) shall be deemed to apply to the Century Letters of Credit (as defined
in this Amendment), and that all agreements of the Borrowers contained in the
Loan Agreement with respect to the Letters of Credit shall be deemed to be
agreements of the Guarantor with respect to the Century Letters of Credit. In
furtherance and not in limitation of the foregoing:

         (1)      The Guarantor hereby specifically agrees to protect,
                  indemnify, pay and save the Lenders and the Agent harmless
                  from and against any and all claims, demands, liabilities,
                  damages, losses, costs, charges and expenses (including
                  reasonable attorneys' fees) which any Lender or the Agent may
                  incur or be subject to as a consequence, direct or indirect,
                  of the issuance of any Century Letter of Credit or the
                  provision of any credit support or enhancement in connection
                  therewith.

         (2)      As among the Guarantor, the Lenders, and the Agent, the
                  Guarantor, subject to paragraphs (3) and (4) below, assumes
                  all risks of the acts and omissions of, or misuse of any of
                  the Century Letters of Credit by, the respective beneficiaries
                  of such Century Letters of Credit. In furtherance and not in
                  limitation of the foregoing, subject to the provisions of the
                  application for the issuance of the Century Letters of Credit,
                  the Lenders and the Agent shall not be responsible for: (A)
                  the form, validity, sufficiency, accuracy, genuineness or
                  legal effect of any document submitted by any Person in
                  connection with the application for and issuance of and
                  presentation of drafts with respect to any of the Century
                  Letters of Credit, even if it should prove to be in any or all
                  respects invalid, insufficient, inaccurate, fraudulent or
                  forged; (B) the validity or sufficiency of any instrument
                  transferring or assigning or purporting to transfer or assign
                  any Century Letter of Credit or the rights or benefits
                  thereunder or proceeds thereof, in whole or in part, 

                                       40
<PAGE>   24
                  which may prove to be invalid or ineffective for any reason;
                  (C) the failure of the beneficiary of any Century Letter of
                  Credit to comply duly with conditions required in order to
                  draw upon such Century Letter of Credit; (D) errors,
                  omissions, interruptions, or delays in transmission or
                  delivery of any messages, by mail, cable, telegraph, telex or
                  otherwise, whether or not they be in cipher; (E) errors in
                  interpretation of technical terms; (F) any loss or delay in
                  the transmission or otherwise of any document required in
                  order make a drawing under any Century Letter of Credit or of
                  the proceeds thereof; (G) the misapplication by the
                  beneficiary of any Century Letter of Credit of the proceeds of
                  any drawing under such Century Letter of Credit; or (H) any
                  consequences arising from causes beyond the control of the
                  Lenders or the Agent, including, without limitation, any act
                  or omission, whether rightful or wrongful, of any present or
                  future de jure or de facto Governmental Authority. None of the
                  foregoing shall affect, impair or prevent the vesting of any
                  rights or powers of the Agent or any Lender under this
                  Consent.

         (3)      In furtherance and extension, and not in limitation, of the
                  specific provisions set forth above, any action taken or
                  omitted by the Agent or any Lender under or in connection with
                  any of the Century Letters of Credit or any related
                  certificates, if taken or omitted in the absence of gross
                  negligence or willful misconduct, shall not put the Agent or
                  any Lender under any resulting liability to either Borrower or
                  the Guarantor or relieve each Borrower or the Guarantor of any
                  of its obligations under the Loan Agreement or hereunder to
                  any such Person.

         (4)      Nothing contained in this Consent shall be deemed to govern
                  the relation of the Guarantor and the issuer of any Century
                  Letter of Credit; it being understood that the Guarantor may
                  be requested to execute and deliver to the issuer of any
                  Century Letter of Credit such documents and agreements as such
                  issuer may require to issue such Century Letter of Credit.

                              EMPLOYMENT AGREEMENT

            Agreement, made as of the 15 day of April, 1998 by and between
Century Aluminum Company, a Delaware corporation (the "Company"), and Lawrence

            THE PARTIES AGREE as follows:

            1. Position and Term of Employment. Executive's employment hereunder
shall commence as of April 15, 1998 and shall end April 14, 2001, unless
terminated sooner pursuant to Section 7 of this Agreement or extended by the
mutual agreement of the parties. During the term hereof, Executive shall be
employed as Executive Vice President of the Company and shall devote his full
business time, skill, attention and best efforts in carrying out his duties and
promoting the best interests of the Company. Executive shall also serve as a
director and/or officer of one or more of the Company's subsidiaries as may be
requested from time to time by the Board of Directors. Subject always to the

responsible for the development and implementation of the Company's long-term
growth strategy and the Company's efforts in corporate and business development.

                                       42
<PAGE>   2
                  Executive shall not at any time while employed by the Company
or any of its affiliates (as defined in the Severance Protection Agreement
between the Company and Executive dated the date hereof (the "SPA")), without
the prior consent of the Board of Directors, knowingly acquire any financial
interests, directly or indirectly, in or perform any services for or on behalf
of any business, person or enterprise which undertakes any business in
substantial competition with the business of the Company and its affiliates or
sells to or buys from or otherwise transacts business with the Company and its
affiliates; provided that Executive may acquire and own not more than five
percent (5%) of the outstanding capital stock of any public corporation which
sells or buys from or otherwise transacts business with the Company and its
affiliates.

                           2.1 Base Salary. (a) (i) Executive shall be paid an
initial salary at the monthly rate of $21,666.68, which shall be paid in
accordance with the Company's normal payroll practice with respect to salaried
employees, subject to applicable payroll taxes and deductions (the "Base
Salary"). Executive's Base Salary shall be subject to review and possible change
in accordance with the usual practices and policies of the Company. However,
Executive's base annual salary shall not be reduced to less than $260,000.

                           (ii) If for any reason other than Executive's
voluntary resignation or termination pursuant to Section 7(a) or (c) hereof,
Executive does not continue to be employed by the Company, Executive shall
continue to receive an amount equal to his then current Base Salary plus an
annual performance bonus equal to the highest annual bonus payment Executive has
received in the previous three years for the then remaining balance of the term
of this Agreement. In no event shall such payment be less than one year's base
salary plus such highest annual bonus. The foregoing amounts shall be paid to
Executive over the remaining term of this 

                                       43
<PAGE>   3
Agreement or one year (whichever is applicable) in accordance with the Company's
payroll and bonus payment policies. Notwithstanding the foregoing, no payments
under this subparagraph (ii) shall be made if the Company makes all payments to
Executive required to be made, if any, under the SPA.

                  (b) If Executive resigns voluntarily or ceases to be employed
by the Company (or any affiliate) for any reason described in Section 7(a) or
(c) of this Agreement, all benefits described in Sections 2 and 4 hereof shall
terminate (except to the extent previously earned or vested).

                  (c) If Executive's employment shall have been terminated
pursuant to Section 7(b), the Company shall pay in equal monthly installments
for the then remaining balance of the term of this Agreement to Executive (or
his beneficiaries or personal representatives, as the case may be) disability
benefits at a rate per annum equal to one hundred percent (100%) of his then
current Base Salary, plus amounts equal to the highest annual bonus as provided
in clause (ii) of Section 2.1 (a), less payments and benefits, if any, received
under any disability plan or insurance provided by the Company and less any
"sick leave" payments received from the Company for the applicable period.

                  2.2 Bonuses. Executive shall be eligible for an annual
performance bonus for calendar years beginning after December 31, 1997, in
amounts between 30 percent and 75 percent of his Base Salary upon achievement by
the Company of targets as determined by the Compensation Committee of the Board
of Directors of the Company.

                  2.3 Expenses. During the term hereof, the Company shall pay or
reimburse Executive in accordance with the Company's normal practices (i) any
travel, hotel and other 

                                       44
<PAGE>   4
expenses or disbursements reasonably incurred or paid by Executive in connection
with the services performed by Executive hereunder and (ii) reasonable expenses
incurred in connection with Executive's relocation to the Monterey, California
area; in each case upon presentation by Executive of itemized accounts of such
expenditures or such other supporting information as the Company may require.

                  3.1 Incentive Plan. Century will grant to Executive, effective
as of April 15, 1998, ten-year options (the "Options") to purchase shares of
Company Common Stock ("Shares") under the Company's 1996 Stock Incentive Plan
(the "Plan") as follows:

                  (a) Seventy five thousand (75,000) shares at an exercise price
per share equal to $15.25.

                  (b) In addition, Executive may be granted additional options
to purchase shares as may hereafter be determined by the Compensation Committee
of the Board of Directors of the Company under the Plan.

                  (c) Of the Shares described in Section 3.1(a), Options to
purchase twenty five thousand (25,000) Shares will vest effective April 15, 1998
(the "Effective Date"), Options to purchase twenty five thousand (25,000) Shares
will vest one year after the Effective Date, and Options to purchase twenty five
thousand (25,000) Shares will vest two years after the Effective Date; provided,
however, that except to the extent provided in the SPA, the Plan or in Section
3.3 hereof, such vesting shall only occur if Executive is an employee of the
Company (or any affiliate) on the relevant vesting date. The Company shall
maintain the Plan and issue the Options in a manner such that, to the maximum
extent possible, the Options are treated as 

                                       45
<PAGE>   5
"incentive stock options," as defined in Section 422 of the Internal Revenue
Code of 1986, as amended.

                  3.2 Performance Share Unit Awards. The Company hereby grants
to Executive, effective the date hereof, seventy-five thousand (75,000)
performance share units. Upon vesting of the performance share units, the
Company shall provide to Executive one Share per performance share unit. The
performance share units shall vest as follows:

                  (a) Twenty five thousand (25,000) performance share units on
the third anniversary of the Effective Date, twenty five thousand (25,000)
performance share units on the fourth anniversary of the Effective Date, and
twenty five thousand (25,000) performance share units on the fifth anniversary
of the Effective Date; provided, however, that, except to the extent otherwise
provided in the SPA, the Plan or Section 3.3 hereof, such vesting shall only
occur if Executive is an employee of the Company (or any affiliate) on the
relevant vesting date.

                  (b) In addition, Executive may be granted additional
performance share units as may hereafter be determined by the Compensation
Committee of the Board of Directors of the Company under the Plan.

                  3.3 Effect of Termination of Employment. (a) If Executive
shall resign voluntarily or cease to be employed by the Company (or an
affiliate) for any reason described in Section 7(c) of this Agreement, except as
provided in the SPA, all benefits described in Section 3 hereof shall terminate
(except to the extent previously earned or vested).

                  (b) If Executive shall die or become disabled, all Options and
performance shares units which have not vested will accelerate and vest
immediately, and, in the event of Executive's  

                                       46
<PAGE>   6
death, all Option rights provided under this Agreement will transfer to
Executive's representative. All then unexercised Options will be cancelled one
year after Executive dies or becomes disabled.

                  4.1     Other Benefits. Executive shall be entitled to (i)
participate in life, medical, dental, hospitalization, disability and life
insurance benefit plans made available by the Company to its salaried employees
and shall also be eligible to participate in existing retirement or pension
plans offered by the Company to its salaried employees, but, except as otherwise
provided in Section 4.2, subject in each case to the terms and requirements of
each such plan or program.

                  4.2     Supplemental Executive Retirement Benefit.

                  (a) Benefit, Service Credit and Offsets. The Company agrees to
provide Executive with a Supplemental Executive Retirement Benefit ("SERB")
providing an annual retirement benefit beginning at age sixty-two (62) or
thereafter, equal to the benefits which would have accrued to Executive under
the Salaried Employees Retirement Plan (the "Pension Plan") and the
contributions which would have been made to the Salaried Employee Defined
Contribution Retirement Plan (the "Defined Contribution Plan") on behalf of
Executive (hereinafter collectively referred to as the "Qualified Plans"),
computed as follows:

                           (i) The limitation on benefits and contributions with
respect to such employees under Section 415 of the Internal Revenue Code of
1986, as at any time amended, and the regulations thereunder (hereinafter the
"Code") shall not be given effect;

                                       47
<PAGE>   7
                           (ii) Such accrued benefits and deemed contributions
shall be determined without giving effect to the one hundred and fifty thousand
dollar ($150,000) limitation of Code Section 401 (a)(17), or any successor
thereto; and

                           (iii) Any and all amounts due Executive under the
Qualified Plans shall be credited toward and shall reduce the benefits payable
under the SERB.

                  (b) Vesting. Notwithstanding the provisions of the Qualified
Plans, the SERB shall be fully vested and there shall be no reduction in the
benefits hereunder because of the number of years of service of Executive.

                  (c) Time and Method of Payment of Benefits. Benefit payments
hereunder shall be made to Executive in the same manner as provided under the
Qualified Plans. Except as otherwise provided in the Qualified Plans, no
benefits shall be payable hereunder prior to death, disability or severance of
employment.

                  (d) Prohibition on Assignment. Executive's right to benefit
payments under this Section 4.2 are not subject in any manner to anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance, attachment or
garnishment by creditors of Executive or Executive's beneficiary.

                  (e) Source of Payments. All benefits under this Section 4.2
shall be paid in cash from the general funds of the Company, and no special or
separate fund shall be established or other segregation of assets made to assure
such payments; provided, however, that the Company may establish a bookkeeping
reserve to meet its obligations hereunder. It is the intention of the 

                                       48
<PAGE>   8
parties that the arrangements be unfunded for tax purposes and for purposes of
Title I of the Employee Retirement Income Security Act of 1974.

                  (f) Executive's Status. Executive shall have the status of a
general unsecured creditor of the Company and the SERB shall constitute a mere
promise to make benefit payments in the future.

                  (g) Survival of Benefit. The SERB shall survive any
termination (or non-renewal) of this Agreement, including, without limitation, a
termination pursuant to Section 7(c) hereof.

                  5. Confidential Information. Except as specifically permitted
by this Section 5, and except as required in the course of his employment with
the Company, while in the employ of the Company or thereafter, Executive will
not communicate or divulge to or use for the benefit of himself or any other
person, firm, association, or corporation without the prior written consent of
the Company, any Confidential Information (as defined herein) owned, or used by
the Company or any of its affiliates that may be communicated to, acquired by or
learned of by Executive in the course of, or as a result of, Executive's
employment with the Company or any of its affiliates. All Confidential
Information relating to the business of the Company or any of its affiliates
which Executive shall use or prepare or come into contact with shall become and
remain the sole property of the Company or its affiliates.

                  "Confidential Information" means information not generally
known about the Company and its affiliates, services and products, whether
written or not, including information relating to research, development,
purchasing, marketing plans, computer software or programs,

                                       49
<PAGE>   9
any copyrightable material, trade secrets and proprietary information,
including, but not limited to, customer lists.

                  Executive may disclose Confidential Information to the extent
it (i) becomes part of the public domain otherwise than as a result of
Executive's breach hereof or (ii) is required to be disclosed by law. If
Executive is required by applicable law or regulation or by legal process to
disclose any Confidential Information, Executive will provide the Company with
prompt notice thereof so as to enable the Company to seek an appropriate
protective order.

                  Upon request by the Company, Executive agrees to deliver to
the Company at the termination of Executive's employment, or at such other times
as the Company may request, all memoranda, notes, plans, records, reports and
other documents (and all copies thereof) containing Confidential Information
that Executive may then possess or have under his control.

                  6. Assignment of Patents and Copyrights. Executive shall
assign to the Company all inventions and improvements within the existing or
contemplated scope of the Company's business made by Executive while in the
Company's employ, together with any such patents or copyrights as may be
obtained thereon, both domestic and foreign. Upon request by the Company and at
the Company's expense, Executive will at any time during his employment with the
Company and after termination regardless of the reason therefor, execute all
proper papers for use in applying for, obtaining and maintaining such domestic
and foreign patents and/or copyrights as the Company may desire, and will
execute and deliver all proper assignments therefor.

                  7. Termination.

                           (a) This Agreement shall terminate upon Executive's
death.

                           (b) The Company may terminate Executive's employment
         hereunder upon fifteen (15) days' written notice if in the opinion of
         the Board of Directors, Executive's physical or mental disability has
         continued or is expected to continue for one hundred and eighty (180)
         consecutive days and as a result thereof, Executive will be unable to
         continue the proper performance of his duties hereunder. For the
         purpose of determining disability, Executive agrees to submit to such
         reasonable physical and mental examinations, if any, as the Board of
         Directors may request and hereby authorizes the examining person to
         disclose his findings to the Board of Directors of the Company.

                           (c) The Company may terminate Executive's employment
         hereunder "for cause" (as hereinafter defined). If Executive's
         employment is terminated for cause, Executive's salary and all other
         rights not then vested under this Agreement shall terminate upon
         written notice of termination being given to Executive. As used herein,
         the term "for cause" means the occurrence of any of the following:

                                    (i) Executive's disregard of a direct,
                           material order of the Executive Committee or the
                           Board of Directors of the Company, the substance of
                           which order is (a) a proper duty of Executive
                           pursuant to this Agreement, (b) permitted by law and
                           (c) otherwise permitted by this Agreement, which
                           disregard continues after fifteen (15) days'
                           opportunity and failure to cure; or

                                    (ii) Executive's conviction for a felony or
                           any crime involving moral turpitude.

                  8. Successors and Assigns. This Agreement is intended to bind
and inure to the benefit of and be enforceable by Executive and the Company and
their respective legal representatives, successors and assigns. Neither this
Agreement nor any of the duties or obligations hereunder shall be assignable by
Executive.

                  9. Governing Law; Jurisdiction. This Agreement shall be
interpreted and construed in accordance with the laws of the State of
California. Each of the Company and 

                                       51
<PAGE>   11
Executive consents to the jurisdiction of any state or federal court sitting in
California, in any action or proceeding arising out of or relating to this
Agreement.

                  10. Headings. The paragraph headings used in this Agreement
are for convenience of reference only and shall not constitute a part of this
Agreement for any purpose or in any way affect the interpretation of this
Agreement. 

                  11. Severability. If any provision, paragraph or subparagraph
of this Agreement is adjudged by any court to be void or unenforceable in whole
or in part, this adjudication shall not affect the validity of the remainder of
this Agreement.

agreement and understanding among the parties, written or oral, which may have
related to the subject matter hereof in any way and shall not be amended orally,

more separate counterparts, all of which taken together shall constitute one and

                         SEVERANCE PROTECTION AGREEMENT


         THIS AGREEMENT, made as of the 15th day of April 1998, by and between
the Company (as hereinafter defined) and Lawrence B. Frost (the "Executive").


                              W I T N E S S E T H :


         WHEREAS, the Board of Directors of the Company (the "Board") recognizes
that the possibility of a Change in Control (as hereinafter defined) exists and
that the threat or the occurrence of a Change in Control can result in
significant distractions of its key management personnel because of the
uncertainties inherent in such a situation;

         WHEREAS, the Board has determined that it is essential and in the best
interest of the Company and its stockholders to retain the services of the
Executive in the event of a threat or the occurrence of a Change in Control and
to ensure his continued dedication and efforts in such event without undue
concern for his personal financial and employment security; and

         WHEREAS, the Executive is the Executive Vice President Officer of the
Company and in order to induce the Executive to remain in the employ of the
Company, particularly in the event of a threat or the occurrence of a Change in
Control, the Company desires to enter into this



                                       53
<PAGE>   2
Agreement with the Executive to provide the Executive with certain benefits in
the event his employment is terminated as a result of, or in connection with, a
Change in Control;

         NOW, THEREFORE, in consideration of the respective agreements of the
parties contained herein, it is hereby agreed as follows:

         1. Term of Agreement. This Agreement shall commence effective upon 15
April 1998, and shall continue in effect until January 1, 2001, provided,
however, that commencing on January 1, 2001 and on each January 1 thereafter,
the term of this Agreement shall automatically be extended for one (1) year,
subject, however, to termination as provided in the last sentence of this
Section 1; and provided, further, however, that the term of this Agreement shall
not expire prior to the later of (i) the expiration of eighteen (18) months
after the occurrence of a Change in Control during the term of this Agreement,
or (ii) until such time as all benefits to be provided for hereunder have been
provided in full. Except as otherwise provided herein, this Agreement and the
rights and obligations of each party shall terminate if the Executive or the
Company terminates the Executive's employment prior to the occurrence of a
Change in Control.

         2.       Definitions.

                  2.1 Accrued Compensation. For purposes of this Agreement,
"Accrued Compensation" shall mean an amount which shall include all amounts
earned or accrued through the Termination Date (as hereinafter defined) but not
paid as of the Termination Date, including (i) base salary, (ii) reimbursement
for reasonable and necessary expenses incurred by the Executive on behalf of the
Company during the period ending on the Termination Date, (iii) vacation pay,
and (iv) bonuses and incentive compensation (other than the "Pro Rata Bonus" (as
hereinafter defined)).

                                       54
<PAGE>   3
                  2.2 Cause. For purposes of this Agreement, a termination of
employment is for "Cause" if the Executive (a) has disregarded a direct,
material order of the Board or the Executive Committee of the Board, the
substance of which order is (i) a proper duty of the Executive under the terms
of his Employment Agreement, (ii) permitted by law, and (iii) otherwise
permitted by his Employment Agreement, which disregard continues after fifteen
(15) days' opportunity and failure to cure, or (b) has been convicted of a
felony or any crime involving moral turpitude.

                  2.3 Change in Control. For purposes of this Agreement, a
"Change in Control" shall mean any of the following events:

                      (a) An acquisition (other than directly from the Company)
of any voting securities of the Company (the "Voting Securities") by any
"Person" (as the term person is used for purposes of Section 13(d) or 14(d) of
the 1934 Act) immediately after which such Person has "Beneficial Ownership"
(within the meaning of Rule 13d-3 promulgated under the 1934 Act) of twenty
percent (20%) or more of the combined voting power of the Company's then
outstanding Voting Securities; provided, however, that in determining whether a
Change in Control has occurred, Voting Securities which are acquired in a
Non-Control Acquisition (as hereinafter defined) shall not constitute an
acquisition which would cause a Change in Control. A "Non-Control Acquisition"
shall mean an acquisition by (1) an employee benefit plan (or a trust forming a
part thereof) maintained by (x) the Company or (y) any corporation or other
Person of which a majority of its voting power or its equity securities or
equity interest is owned directly or indirectly by the Company (a "Subsidiary"),
(2) the Company or any Subsidiary, or (3) any Person in connection with a
Non-Control Transaction (as hereinafter defined);

                                       55
<PAGE>   4
                    (b) The individuals who, as of the date hereof, are members
of the Board (the "Incumbent Board"), cease for any reason to constitute at
least two-thirds of the Board; provided, however, that if the election, or
nomination for election by the Company's stockholders, of any new director was
approved by a vote of at least two-thirds of the Incumbent Board, such new
director shall, for purposes of this Agreement, be considered a member of the
Incumbent Board; provided, further, however, that no individual shall be
considered a member of the Incumbent Board if such individual initially assumed
office as a result of either an actual or threatened "Election Contest" (as
described in Rule 14a-11 promulgated under the 1934 Act) or other actual or
threatened solicitation of proxies or consents by or on behalf of a Person other
than the Board (a "Proxy Contest") including by reason of any agreement intended
to avoid or settle any Election Contest or Proxy Contest; or

                           (c)      Approval by stockholders of the Company of:

                                    (1) A merger, consolidation or
                           reorganization involving the Company, unless

                                    (i) the stockholders of the Company,
immediately before such merger, consolidation or reorganization, own, directly
or indirectly immediately following such merger, consolidation or
reorganization, at least seventy percent (70%) of the combined voting power of
the outstanding voting securities of the corporation resulting from such merger
or consolidation or reorganization (the "Surviving Corporation") in
substantially the same proportion as their ownership of the Voting Securities
immediately before such merger, consolidation or reorganization,

                                    (ii) the individuals who were members of the
Incumbent Board immediately prior to the execution of the agreement providing
for such merger,



                                       56
<PAGE>   5
consolidation or reorganization constitute at least two-thirds
of the members of the board of directors of the Surviving Corporation, and

                                    (iii) no Person (other than the Company, any
Subsidiary, any employee benefit plan (or any trust forming a part thereof)
maintained by the Company, the Surviving Corporation or any Subsidiary, or any
Person who, immediately prior to such merger, consolidation or reorganization,
had Beneficial Ownership of fifteen percent (15%) or more of the then
outstanding Voting Securities) has Beneficial Ownership of fifteen percent (15%)
or more of the combined voting power of the Surviving Corporation's then
outstanding voting securities (a transaction described in clauses (i) through
(iii) above shall herein be referred to as a "Non-Control Transaction");

                           (2) A complete liquidation or dissolution of the
Company; or

                           (3) An agreement for the sale or other disposition of
all or substantially all of the assets of the Company to any Person (other than
a transfer to a Subsidiary).

         Notwithstanding the foregoing, a Change in Control shall not be deemed
to occur solely because any Person (the "Subject Person") acquired Beneficial
Ownership of more than the permitted amount of the outstanding Voting Securities
as a result of the acquisition of Voting Securities by the Company which, by
reducing the number of Voting Securities outstanding, increases the proportional
number of shares Beneficially Owned by the Subject Person, provided that if a
Change in Control would occur (but for the operation of this sentence) as a
result of the acquisition of Voting Securities by the Company, and after such
share acquisition by the Company, the Subject Person becomes the Beneficial
Owner of any additional Voting Securities



                                       57
<PAGE>   6
which increases the percentage of the then outstanding Voting Securities
beneficially owned by the Subject Person, then a Change in Control shall occur.

                           (d) Notwithstanding anything contained in this
Agreement to the contrary, if the Executive's employment is terminated prior to
a Change in Control and the Executive reasonably demonstrates that such
termination (i) was at the request of a third party who had indicated an
intention or taken steps reasonably calculated to effect a Change in Control and
who effectuates a Change in Control (a "Third Party") or (ii) otherwise occurred
in connection with, or in anticipation of, a Change in Control which actually
occurs, then for all purposes of this Agreement, the date of a Change in Control
with respect to the Executive shall mean the date immediately prior to the date
of such termination of the Executive's employment.

                  2.4 Company. For purposes of this Agreement, the "Company"
shall mean Century Aluminum Company, a Delaware corporation, and shall include
its Successors and Assigns (as hereinafter defined). As used in this Agreement,
the term "affiliates" shall include any company controlled by, controlling, or
under common control with, the Company.

                  2.5 Disability. For purposes of this Agreement, "Disability"
shall mean a physical or mental infirmity which impairs the Executive's ability
to substantially perform his duties with the Company for a period of one hundred
eighty (180) consecutive days and the Executive has not returned to his full
time employment prior to the Termination Date as stated in the Notice of
Termination (as hereinafter defined).

                           (a) For purposes of this Agreement, "Good Reason"
shall mean the occurrence after a Change in Control of any of the events or
conditions described in subsections (1) through (9) hereof:

                                    (1) a change in the Executive's status,
title, position or responsibilities (including reporting responsibilities)
which, in the Executive's reasonable judgment, represents an adverse change from
his status, title, position or responsibilities as in effect at any time within
one year preceding the date of a Change in Control or at any time thereafter;
the assignment to the Executive of any duties or responsibilities which, in the
Executive's reasonable judgment, are inconsistent with his status, title,
position or responsibilities as in effect at any time within one year preceding
the date of a Change in Control or at any time thereafter; or any removal of the
Executive from or failure to reappoint or reelect him to any of such offices or
positions, except in connection with the termination of his employment for
Disability, Cause, as a result of his death or by the Executive other than for

recently completed fiscal year prior to the Change in Control, such bonus to be
paid no later than the end of the third month of the fiscal year next following
the fiscal year for which the annual bonus is awarded, unless the Executive
shall elect to defer the receipt of such annual bonus, (ii) increase the
Executive's base salary and annual bonus consistent with the Company's practice
prior to the Change in Control or, if greater, as the same may be increased from
time to time for other key executive officers of the Company and its



                                       59

affiliated companies, or (iii) pay to the Executive any compensation or benefits

executive offices prior to the Change in Control, except for reasonably required
travel on the Company's business which is not materially greater than such

                                    (4) the failure by the Company to (A)
continue in effect (without reduction in benefit level and/or reward
opportunities) any material compensation or employee benefit plan (including,
without limitation, long-term disability, medical, dental, life insurance,
flexible spending account, pre-tax insurance premiums, vacation pay, pension and

Control or at any time thereafter, or (C) permit the Executive to participate in
any or all incentive, savings, retirement plans and benefit plans, fringe

Accrued Compensation and a Pro Rata Bonus;

                                    (ii) the Company shall pay the Executive as
severance pay and in lieu of any further compensation for periods subsequent to
the Termination Date, in a

<PAGE>   12
single payment an amount in cash equal to three times the sum of (A) the Highest
Base Salary and (B) the Highest Annual Bonus;

                                    (iii) for a period of thirty-six (36) months
after the Termination Date (the "Continuation Period"), the Company shall, at
its expense, continue on behalf of the Executive and his dependents and
beneficiaries all employee benefits provided (x) to the Executive at any time
during the one year period prior to the Change in Control or at any time
thereafter or (y) to other similarly situated executives who continue in the
employ of the Company during the Continuation Period, including, but not limited
to, long-term disability, medical, dental, life insurance, flexible spending
account and pre-tax insurance premiums but excluding pension and profit-sharing
benefits. The coverage and benefits (including deductibles and costs) provided
in this Section 3.1(b)(iii) during the Continuation Period shall be no less
favorable to the Executive and his dependents and beneficiaries than the most
favorable of such coverages and benefits during any of the periods referred to
in clauses (x) and (y) above. The Company's obligation hereunder with respect to
the foregoing benefits shall be limited to the extent that the Executive obtains
any such benefits pursuant to a subsequent employer's benefit plans, in which
case the Company may reduce the coverage of any benefits it is required to
provide the Executive hereunder as long as the aggregate coverages and benefits
of the combined benefit plans is no less favorable to the Executive than the
coverages and benefits required to be provided hereunder. This subsection (iii)
shall not be interpreted so as to limit any benefits to which the Executive, his
dependents or beneficiaries may be entitled under any of the Company's employee
benefit plans, programs or practices following the Executive's termination of
employment, including, without limitation, retiree medical and life insurance
benefits;

                                    (iv) the Company shall pay to the Executive
in a single payment an amount in cash equal to the excess of (A) the
Supplemental Retirement Benefit (as defined below) had (w) the Executive
remained employed by the Company for an additional three (3)



                                       64
<PAGE>   13
complete years of credited service, (x) his annual compensation during such
period been equal to the Highest Base Salary and the Highest Annual Bonus, (y)
the benefit accrual formulas of each retirement plan remained no less
advantageous to the Executive than those in effect immediately preceding the
date on which a Change in Control occurred and the Company made employer
contributions to each defined contribution plan in which the Executive was a
participant at the Termination Date in an amount equal to the amount of such
contribution for the plan year immediately preceding the Termination Date, and
(z) he been fully (100%) vested in his benefit under each retirement plan in
which the Executive was a participant, over (B) the lump sum actuarial
equivalent of the aggregate retirement benefit the Executive is actually
entitled to receive under such retirement plans. For purposes of this subsection
(iv), the "Supplemental Retirement Benefit" shall mean the lump sum actuarial
equivalent of the aggregate retirement benefit the Executive would have been
entitled to receive under the Company's supplemental and other retirement plans
(the "Pension Plans"). For purposes of this subsection (iv), the "actuarial
equivalent" shall be determined in accordance with the actuarial assumptions
used for the calculation of benefits under the Pension Plans as applied prior to
the Termination Date in accordance with such plans' past practices; and

                           (v) (A) the restrictions on any outstanding incentive
awards (including restricted stock and performance share units) granted to the
Executive under the 1996 Stock Incentive Plan or under any other incentive plan
or arrangement shall lapse and such incentive awards shall become 100% vested
and all stock options granted to the Executive shall become immediately
exercisable and shall become 100% vested (and restrictions on any stock issued
upon exercise of stock options shall lapse), and (B) the Executive shall have

unrestricted stock or shares purchased upon exercise of any options at a price
equal to the fair market value of such shares on the date of purchase by the
Company.

                           (c) The amounts provided for in Sections 3.1(a),
3.1(b)(i), 3.1(b)(ii) and 3.1(b)(iv) shall be paid in a single lump sum cash
payment within five (5) days after the Executive's Termination Date (or earlier,
if required by applicable law).

                           (d) The Executive shall not be required to mitigate
the amount of any payment provided for in this Agreement by seeking other
employment or otherwise and no such payment shall be offset or reduced by the
amount of any compensation or benefits provided to the Executive in any
subsequent employment except as provided in Section 3.1(b)(iii). Notwithstanding
the foregoing, the Executive agrees that during the Continuation Period, he
shall not (i) solicit any employees of the Company to leave the Company's employ
to work for any company with which the Executive is employed, or (ii) employ any
employee who is employed by the Company at any time during the Continuation
Period. A breach of either of the foregoing covenants will result in the
Executive forfeiting any further benefits to which he is entitled pursuant to
Section 3.1(b)(iii), although the Executive shall not be required to return any
payments to the Company which have been made to the Executive prior to the date
of such breach.

         3.2 (a) The severance pay and benefits provided for in this Section 3
shall be in lieu of any other severance or termination pay to which the
Executive may be entitled under any employment agreement or any Company
severance or termination plan, program, practice or arrangement.

                  (b) The Executive's entitlement to any other compensation
benefits shall be determined in accordance with the Company's employee benefit
plans and other applicable programs, policies and practices then in effect.

<PAGE>   15
                  (c) Notwithstanding anything to the contrary in this
Agreement, in the event the Executive is terminated by the Company after the
occurrence of a Change in Control and is subsequently rehired by the Company at
any time thereafter, the Executive shall not be entitled to any further benefits
under Section 3.1(b)(iii) of this Agreement although the Executive shall not be
required to return any payments to the Company which have been made to the
Executive prior to the date the Executive is rehired.

         4. Notice of Termination. Following a Change in Control, any purported
termination of the Executive's employment by the Company shall be communicated
by Notice of Termination to the Executive. For purposes of this Agreement, no
such purported termination shall be effective without such Notice of
Termination.

         5. Excise Tax Payments.

                  (a) In the event that any payment or benefit (within the
meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended
(the "Code")) to the Executive or for his benefit paid or payable or distributed
or distributable pursuant to the terms of this Agreement or otherwise in
connection with, or arising out of, his employment with the Company or a change
in ownership or effective control of the Company or of a substantial portion of
its assets (each a "Payment" and collectively, the "Payments"), would be subject
to the excise tax imposed by Section 4999 of the Code or any interest or
penalties are incurred by the Executive with respect to such excise tax (such
excise tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then the Executive will be
entitled to receive an additional payment (a "Gross-Up Payment"), such that the
net amount retained by the Executive, after deduction and/or payment of any
Excise Tax on the Payments and the Gross-Up Payment and any federal, state and
local income tax on the Gross-Up Payment (including any interest or penalties,
other than interest and penalties imposed by reason of the Executive's



                                       67
<PAGE>   16
failure to file timely a tax return or pay taxes shown due on his return,
imposed with respect to such taxes), shall be equal to the Payments.
Notwithstanding the foregoing, the Company shall only be required to make a
Gross-Up Payment with respect to parachute payments (as defined in Section
280G(b)(2) of the Code) arising from or relating to the acceleration, vesting or
lapsing of restrictions of incentive awards, including without limitation, stock
options, performance share units and restricted stock; any such Gross-Up Payment
shall be made with respect to the full amount of such parachute payments without
regard to the base amount (as defined in Section 280G(b)(3) of the Code).

                  (b) An initial determination as to whether a Gross-Up Payment
is required pursuant to this Agreement and the amount of such Gross-Up Payment
shall be made at the Company's expense by an accounting firm selected by the
Company and reasonably acceptable to the Executive which is designated as one of
the five largest accounting firms in the United States (the "Accounting Firm").
The Accounting Firm shall provide its determination (the "Determination"),
together with detailed supporting calculations and documentation to the Company
and the Executive within five days of the Termination Date if applicable, or
such other time as requested by the Executive (provided the Executive reasonably
believes that any of the Payments may be subject to the Excise Tax) and if the
Accounting Firm determines that no Excise Tax is payable by the Executive as
provided in Section 5(a) above, it shall furnish the Executive with an opinion
reasonably acceptable to the Executive to such effect. Within ten days of the
delivery of the Determination to the Executive, the Executive shall have the
right to dispute the Determination (the "Dispute"). The Gross-Up Payment, if
any, as determined pursuant to this Paragraph 5(b) shall be paid by the Company
to the Executive within five days of the receipt of the Accounting Firm's
determination. The existence of the Dispute shall not in any way affect the
Executive's right to receive the Gross-Up Payment in accordance with the
Determination. Upon the final resolution of a Dispute, the Company shall
promptly pay to the Executive any additional amount required by such resolution.
If there is no Dispute, the



                                       68
<PAGE>   17
Determination shall be binding, final and conclusive upon the Company and the
Executive subject to the application of Section 5(c) below.

                  (c) As a result of the uncertainty in the application of
Sections 4999 and 280G of the Code, it is possible that a Gross-Up Payment (or a
portion thereof) will be paid which should not have been paid (an "Excess
Payment") or a Gross-Up Payment (or a portion thereof) which should have been
paid will not have been paid (an "Underpayment"). An Underpayment shall be
deemed to have occurred (i) upon notice (formal or informal) to the Executive
from any governmental taxing authority that the Executive's tax liability
(whether in respect of the Executive's current taxable year or in respect of any
prior taxable year) may be increased by reason of the imposition of the Excise
Tax on a Payment or Payments with respect to which the Company has failed to
make a sufficient Gross-Up Payment, (ii) upon a determination by a court, (iii)
by reason of a determination by the Company (which shall include the position
taken by the Company, together with its consolidated group, on its federal
income tax return) or (iv) upon the resolution of the Dispute to the Executive's
satisfaction. If an Underpayment occurs, the Executive shall promptly notify the
Company and the Company shall promptly, but in any event, at least five days
prior to the date on which the applicable government taxing authority has
requested payment, pay to the Executive an additional Gross-Up Payment equal to
the amount of the Underpayment plus any interest and penalties (other than
interest and penalties imposed by reason of the Executive's failure to file
timely a tax return or pay taxes shown due on the Executive's return) imposed on
the Underpayment. An Excess Payment shall be deemed to have occurred upon a
Final Determination (as hereinafter defined) that the Excise Tax shall not be
imposed upon a Payment or Payments (or portion thereof) with respect to which
the Executive had previously received a Gross-Up Payment. A "Final
Determination" shall be deemed to have occurred when the Executive has received
from the applicable government taxing authority a refund of taxes or other
reduction in the Executive's tax liability by reason of the Excess Payment and
upon either (x) the date a determination is made by, or an agreement is entered
into



                                       69
<PAGE>   18
with, the applicable governmental taxing authority which finally and
conclusively binds the Executive and such taxing authority, or in the event that
a claim is brought before a court of competent jurisdiction, the date upon which
a final determination has been made by such court and either all appeals have
been taken and finally resolved or the time for all appeals has expired or (y)
the statute of limitations with respect to the Executive's applicable tax return
has expired. If an Excess Payment is determined to have been made, the amount of
the Excess Payment shall be treated as a loan by the Company to the Executive
and the Executive shall pay to the Company on demand (but not less than 10 days
after the determination of such Excess Payment and written notice has been
delivered to the Executive) the amount of the Excess Payment plus interest at an
annual rate equal to the Applicable Federal Rate provided for in Section 1274(d)
of the Code from the date the Gross-Up Payment (to which the Excess Payment
relates) was paid to the Executive until the date of repayment to the Company.

                  (d) Notwithstanding anything contained in this Agreement to
the contrary, in the event that, according to the Determination, an Excise Tax
will be imposed on any Payment or Payments, the Company shall pay to the
applicable government taxing authorities as Excise Tax withholding, the amount
of the Excise Tax that the Company has actually withheld from the Payment or
Payments.

         6. Successors' Binding Agreement.

                  (e) This Agreement shall be binding upon and shall inure to
the benefit of the Company, its Successors and Assigns and the Company shall
require any Successors and Assigns to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession or assignment had taken place.

                                       70
<PAGE>   19
                  (f) Neither this Agreement nor any right or interest hereunder
shall be assignable or transferable by the Executive, his beneficiaries or legal
representatives, except by will or by the laws of descent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal personal representative.

         7. Fees and Expenses. The Company shall pay all legal fees and related
expenses (including the costs of experts, evidence and counsel) incurred by the
Executive as they become due as a result of (a) the Executive's termination of
employment (including all such fees and expenses, if any, incurred in contesting
or disputing any such termination of employment), (b) the Executive seeking to
obtain or enforce any right or benefit provided by this Agreement (including,
but not limited to, any such fees and expenses incurred in connection with the
Dispute and any other matter arising under Section 5, including the existence
and amount of any Excess Payment or Underpayment and issues with respect to the
Gross-Up Payment, whether as a result of any applicable government taxing
authority proceeding, audit or otherwise, or by any other plan or arrangement
maintained by the Company under which the Executive is or may be entitled to
receive benefits), provided, however, that any such action by the Executive is
commenced in good faith and for good reason, and (c) the Executive's hearing
before the Board as contemplated in Section 2.2 of this Agreement; provided,
however, that the circumstances set forth in clauses (a) and (b) (other than as
a result of the Executive's termination of employment under circumstances
described in Section 2.3(d)) occurred on or after a Change in Control.

         8. Notices. For the purposes of this Agreement, notices and all other
communications provided for in the Agreement (including the Notice of
Termination) shall be in writing and shall be deemed to have been duly given
when personally delivered or sent by certified mail, return receipt requested,
postage prepaid, addressed to the respective addresses for the parties set forth
on Exhibit A hereto or to any other addresses as the respective parties may
designate by notice delivered pursuant to this Section 8, provided that all

                                       71
<PAGE>   20

the Company. All notices and communications shall be deemed to have been
received on the date of delivery thereof or on the third business day after the
mailing thereof, except that notice of change of address shall be effective only
upon receipt.

         9. Non-Exclusivity of Rights. Except as otherwise provided in Section
3.2(a), nothing in this Agreement shall prevent or limit the Executive's
continuing or future participation in any benefit, bonus, incentive or other
plan or program provided by the Company and for which the Executive may qualify,
nor shall anything herein limit or reduce such rights as the Executive may have
under any other agreements with the Company. Amounts which are vested benefits
or which the Executive is otherwise entitled to receive under any plan or
program of the Company shall be payable in accordance with such plan or program,
except as explicitly modified by this Agreement.

         10. Settlement of Claims. The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim, recoupment, defense or other right which
the Company may have against the Executive or others.

         11. Modification, Waiver and Miscellaneous. No provision of this
Agreement may be modified, waived or discharged unless such waiver, modification
or discharge is agreed to in writing and signed by the Executive and the
Company. No waiver by either party hereto at any time of any breach by the other
party hereto of, or compliance with, any condition or provision of this
Agreement to be performed by such other party shall be deemed a waiver of
similar or dissimilar provisions or conditions at the same or at any prior or
subsequent time. No agreement or representations, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either
party which are not expressly set forth in this Agreement.

                  shareholders' equity plus borrowings of the Company, the
                  average in each case to be the sum of the shareholders' equity
                  plus borrowings on the last day of the immediately preceding
                  calendar year and on the last day of the calendar year in
                  question, in all respects as these items appear in the audited

         P.       "Target" shall mean the cumulative annual earnings before
                  income taxes established by the Committee as the goal for the
                  Initial Periods and for each of the Plan Periods, which goal
                  shall be guided by the cumulative forecasted earnings before
                  income taxes of the Company for the first three years of each
                  Five-Year Plan as contained in and submitted to the Board
                  annually in the document entitled "Century Aluminum Company's
                  Five Year Profit Plan". The Committee may use as its guide for
                  the Initial Periods and the first of the Plan Periods the
                  Profit Plan present to the Board by the Company on December
                  18, 1997.

         1998, and shall continue until such time as terminated by the Board.

4.       AWARD

         A.       AWARD. The Committee shall, on or before each May 15 during
                  the Initial Periods and each of the Plan Periods, make an
                  award of Performance Shares to each Participant, which award
                  shall be communicated in writing to each Participant by the
                  Chief Executive Officer of the Company. Awards shall be issued
                  as provided in Section 5. The Award for each Participant shall
                  be determined by creating a monetary award, and converting
                  that monetary award to Performance Share units. The monetary
                  award shall be a percentage of such Participant's base salary
                  (within the allowable range), which percentage shall be
                  established by the Committee at the beginning of each of the
                  Plan Periods. The allowable percentages are as follows:

            Sr. Operating/Corporate Staff                       15 - 30%
</TABLE>

The number of Performance Shares shall be determined by dividing the
Participant's monetary award by the average closing price for the Company's
common stock for the month preceding the month in which the grant is made.

         B.       TARGET AWARD; ADJUSTED AWARD.

                  1. TARGET AWARD. If the Company's Cumulative Earnings Before
                  Tax are at least 100% of Target but not equal to or greater
                  than 105% of such Target, then Participants shall be issued
                  the number of shares equal to the number of Performance Share
                  units in Participants' awards.

                           2. ADJUSTED AWARD. If the Award Factor is other than
                  as described in Section 4.B.(1), the Target Awards shall be
                  adjusted upward or downward as follows:

                  (a)      If a Participant's Award Factor is 105% or greater,
                           the number of Performance Shares in excess of the
                           100% award shall be calculated by dividing the
                           Participant's monetary award in excess of 100% by the
                           greater of the stock value on the date of the initial
                           grant of the Performance Shares or the average stock
                           price for the month immediately preceding the month
                           in which the Performance Shares are issued. An
                           example of how this provision is intended to operate
                           is attached to these Guidelines as Exhibit A.1.

                  (b)      If a Participant's Award Factor is less than 100% of
                           Target, the number of Performance Shares shall be
                           calculated by recalculating the Participant's
                           monetary Award by the applicable Award Factor and
                           converting the monetary award to Performance Share
                           units by the stock value used in calculating the
                           Target Award. An example of how this provision is
                           intended to operate is illustrated on Exhibit A.2.

5.       ISSUANCE OF AWARDS

         A.       On or before March 15 (or, if required, such later date when
                  the annual audited financial statement of the Company and the
                  other companies referred to in the definition of Industry ROI
                  are available) of each calendar year, the Company shall, in
                  respect of the Initial Period or Plan Period which has just
                  ended, issue to each Participant Performance Shares in an
                  amount equal to such Participant's Award multiplied by the
                  applicable Award Factor.

                                       79
<PAGE>   5
         B.       Except as provided in Section 5.C., no grant with respect to
                  any Award shall be made to a Participant who is not employed
                  full time by the Company or a Subsidiary on the 31st day of
                  December preceding the date of issuance provided in Section
                  5.A.

         C.       In the event of death, permanent disability or retirement of a
                  Participant in any year following an Award, the Participant or
                  his representative or designated beneficiaries shall be
                  entitled to receive a portion of the amount calculated under
                  Section 5.A., and payable in the year following death,
                  permanent disability or retirement, determined by multiplying
                  such amount by a fraction, the numerator of which is the
                  number of weeks of full employment during any of the Initial
                  Periods or Plan Periods and the denominator of which is 52 for
                  the first Initial Period, 104 for the second Initial Period
                  and 156 for any Plan Period.

         D.       If an employee is selected as a Participant at any time other
                  than the beginning of any given Initial Period or Plan Period,
                  such Participant shall be entitled to receive a portion of the
                  amount calculated under Section 5.A. by multiplying such
                  amount by a fraction the numerator of which is the number of
                  months that such employee was a Participant under the plan
                  during any of the Initial Period or Plan Periods and the
                  denominator of which is number of months in the applicable
                  period. For the purposes of this Section 5.D. an employee
                  shall be deemed to have been a Participant under the Plan as
                  of January 1 of the calendar year in which such employee was
                  first selected a Participant if such selection occurred on or
                  before May 15 of such calendar year and if such selection
                  occurred after May 15 of any calendar year the employee shall
                  be deemed to have first become a Participant on January 1 of
                  the calendar year immediately following the employee's
                  election as a Participant.

6.       ADMINISTRATION

         A.       Each grant of a Performance Share shall be evidenced by an
                  agreement executed on behalf of the Company by an officer
                  designated by the Compensation Committee and accepted by the
                  recipient. Such agreement shall state that such award is
                  subject to all the terms and provisions of the Plan.

         B.       Full power and authority to amend, modify, terminate,
                  construe, interpret and administer these Guidelines shall be
                  vested in the Committee. Any interpretation of these
                  Guidelines by the Committee or any administrative act by the
                  Committee shall be final and binding on all Participants.

7.       NON-ASSIGNABILITY

         Nothing in these Guidelines shall be deemed to make rights granted
         pursuant hereto assignable or transferable by a Participant except
         pursuant to the laws of descent and distribution. No rights under these
         Guidelines may be hypothecated or encumbered in any manner whatsoever,
         and creditors of Participants shall have no right or power to obtain
         all or any portion of grants made hereunder. Any attempted assignment,

<PAGE>   6
         hypothecation or encumbrance by a Participant shall be null and void.
         Each Participant may, however, designate one or more beneficiaries
         under the Plan on a form to be supplied by the Secretary of the Company


Adopted by the Board on May 4, 1998.

Assume a Participant whose base salary is $200,000 is given a 75% Target Award
and that the Company's common stock has an average closing price of $15 in the
month preceding the month in which the grant is made. This Participant would
have a Target Award of 10,000 Performance Shares ($200,000 x 75% / 15 = 10,000).


1.       Award Factor Greater Than Target

         If the Company achieves 105% of Target, the Participant's monetary
         award (pursuant to the Award Factor described in Section 2.B.(1)) would
         be $165,000 ($150,000 x 110%). The $15,000 by which the adjusted
         monetary award exceeds 100% of the target monetary award would be
         converted to Performance Shares as follows:

         a.       If the Company's average stock price in the month preceding
                  the date in which the grant vests is $15 or less, the
                  additional Award would be 1,000 Performance Shares ($15,000 /
                  15 = 1,000), and the Participant's total Award would be 11,000
                  Performance Shares.

         b.       If the Company stock in the month preceding the date in which
                  the grant vests is greater than $15 (e.g. $20), the adjusted
                  Award would be calculated using the higher share value
                  ($15,000 / 20 = 750), and the Participant's total Award in
                  this case would be 10,750 Performance Shares.


2.       Award Factor Less Than Target

         If the Company achieves 90% of Target, the Participant's monetary award
         would be $127,500 ($150,000 x 85% = $127,500), and the Award would be
         8,500 Performance Shares ($127,500 / 15 = 8,500).

         An award shall be paid only to a Participant who is employed by, or is
         upon an approved leave of absence from, the Company or a Subsidiary on
         the last business day of the year for which an award is made, unless
         termination of employment during such year was due to death,
         disability, retirement or other reason approved by the Committee. If an
         award has been made to a Participant for any year and the employment of
         such Participant by the Company or a Subsidiary has been terminated
         prior to the last business day of such year other than by death,
         disability, retirement or other reason approved by the Committee, no
         award shall be payable to such Participant, and the amount of any award
         to such Participant for such year, shall be credited to the Reserve.

         Awards made to Participants shall be paid in cash and debited to the
         Reserve. Each cash award shall be paid to a Participant, or in the
         event of the death of a Participant prior to the payment thereof, to
         his or her beneficiary or if no beneficiary has been designated or if a
         beneficiary who has been designated dies prior to the receipt of
         payment, to the personal representative of the Participant, no later
         than March 31 of the year following the year for which such award is
         made.

7.       PARTICIPATION

         An employee eligible to be a Participant hereunder shall participate in
         awards only to the extent that the Committee may from time to time
         determine, and any Participant who participates in one year may be
         excluded from participation in any other year.


8.       TERM

         The Plan shall continue until such time as it shall be terminated by
         action of the Board; provided, however, that upon any termination of
         the Plan, awards already made to Participants shall continue to be
         subject to the provisions of the Plan.

9.       ADMINISTRATION

         B.       Full power and authority to construe, interpret and administer
                  the Plan shall be vested in the Committee. Any interpretation
                  of the Plan by the Committee or any administrative act by the
                  Committee shall be final and binding on all Participants.

         C.       The members of the Committee may appoint from their number
                  such committees with such powers as they shall determine, may
                  authorize one or more of their number or any agent to execute
                  or deliver any instrument or instruments in their behalf, and
                  may employ such counsel, agents and other services as they may
                  require in carrying out their duties.
