                        2. THE REVOLVING CREDIT FACILITY.

     2.1.  Commitment to Lend.  Subject to the terms and conditions set forth in
this  Credit  Agreement,  each of the  Lenders  severally  agrees to lend to the
Borrowers and the Borrowers  may borrow,  repay,  and reborrow from time to time
from the Closing Date up to but not  including  the Maturity Date upon notice by
the  Borrowers to the Agent given in  accordance  with ss.2.6,  such sums as are
requested by the Borrowers up to a maximum aggregate amount  outstanding  (after
giving  effect to all amounts  requested) at any one time equal to such Lender's
Revolving  Credit  Commitment minus such Lender's  Commitment  Percentage of all
Letter of Credit  Exposure,  provided that the sum of the outstanding  amount of
the Loans  (after  giving  effect to all amounts  requested)  plus the Letter of
Credit  Exposure  shall  not at any time  exceed  the  lesser  of (i) the  Total
Revolving Credit Commitment and (ii) the Borrowing Base. The Loans shall be made
pro rata in accordance with each Lender's  Commitment  Percentage.  Each request
for a Loan  hereunder  shall  constitute  a  representation  and warranty by the
Borrowers that the conditions set forth in ss.11,  in the case of the conditions
to be satisfied on the Closing Date, and ss.12,  in the case of all other Loans,
have been satisfied on the date of such request.

     2.2. Unused Revolving Credit  Commitment Fee. The Borrowers agree to pay to
the Agent for the accounts of the Lenders in  accordance  with their  respective
Commitment  Percentages  a commitment  fee (the  "Commitment  Fee") in an amount
equal to the  Applicable  Margin  for  Commitment  Fees then in effect per annum
multiplied by the average  daily amount during such calendar  quarter or portion
thereof  by which the Total  Revolving  Credit  Commitment  minus the  Letter of
Credit Exposure exceeds the outstanding  amount of Revolving Credit Loans during
such calendar quarter.  The Commitment Fee shall be payable quarterly in arrears
on the first day of each calendar quarter for the immediately preceding calendar
quarter (or portion  thereof),  commencing on the first such date  following the
date hereof,  with a final  payment on the Maturity  Date or any earlier date on
which the Revolving Credit Commitments shall terminate.

     2.3.  Reduction of Total Revolving Credit  Commitment.  The Borrowers shall
have the right at any time and from time to time  upon  five (5)  Business  Days
prior  written  notice  to the  Agent to reduce  by  $5,000,000  or an  integral
multiple thereof or terminate  entirely the Total Revolving  Credit  Commitment,
whereupon the Revolving  Credit  Commitments of the Lenders shall be reduced pro
rata in accordance with their  respective  Commitment  Percentages of the amount
specified  in such  notice or, as the case may be,  terminated.  Promptly  after
receiving any notice of the  Borrowers  delivered  pursuant to this ss.2.3,  the
Agent will notify the Lenders of the substance thereof.  Upon the effective date
of any such reduction or  termination,  the Borrowers shall pay to the Agent for
the respective  accounts of the Lenders the full amount of any Revolving  Credit
Commitment Fee then accrued on the amount of the reduction.  The Total Revolving
Credit  Commitment  shall never be reduced  pursuant to this ss.2.3 to an amount
less  than the sum of (a) the then  outstanding  amount of the Loans and (b) the
Maximum  Drawing  Amount and all  Reimbursement  Obligations.  No  reduction  or
termination of the Revolving Credit Commitments may be reinstated.


                                      -26-


     2.4. The Revolving  Credit Notes.  The Loans shall be evidenced by separate
promissory notes of the Borrowers in substantially  the form of Exhibit B hereto
(each a "Note"),  dated as of the Closing Date and  completed  with  appropriate
insertions. One Note shall be payable to the order of each Lender in a principal
amount equal to such  Lender's  Revolving  Credit  Commitment  or, if less,  the
outstanding  amount of all Loans  made by such  Lender,  plus  interest  accrued
thereon, as set forth below. Each Borrower irrevocably authorizes each Lender to
make or cause to be made,  at or about the time of the Drawdown Date of any Loan
or at the time of receipt of any payment of principal on such Lender's  Note, an
appropriate  notation on such Lender's Note Record reflecting the making of such
Loan or (as the case may be) the receipt of such payment. The outstanding amount
of the  Loans  set  forth on such  Lender's  Note  Record  shall be prima  facie
evidence of the principal  amount  thereof owing and unpaid to such Lender,  but
the  failure to record,  or any error in so  recording,  any such amount on such
Lender's Note Record shall not limit or otherwise  affect the obligations of the
Borrower  hereunder or under any Note to make  payments of principal or interest
on any Note when due.

     2.5. Interest on Loans. Except as otherwise provided in ss.5.12,

          (a) Each Base Rate Loan shall bear interest for the period  commencing
     with the  Drawdown  Date thereof and ending on the last day of the Interest
     Period with respect thereto at the rate per annum of the Base Rate plus the
     Applicable Margin.

          (b) Each  Eurodollar  Rate Loan  shall  bear  interest  for the period
     commencing with the Drawdown Date thereof and ending on the last day of the
     Interest  Period  with  respect  thereto  at  the  rate  per  annum  of the
     Eurodollar  Rate  determined  for such Interest  Period plus the Applicable
     Margin.

          (c) The Borrowers promise to pay interest on the Loans, or any portion
     thereof  outstanding  during  such  Interest  Period,  in  arrears  on each
     Interest Payment Date with respect thereto.


                                      -27-

     notice in the form of  Exhibit  C hereto,  (b)  telephonic  notice,  or (c)
     electronic  transmittal  in the form of  Exhibit  C  hereto,  of each  Loan
     requested  hereunder  (any such  request a "Loan  Request")  not later than
     12:00 noon (Chicago,  Illinois,  time) on the proposed Drawdown Date of any
     Base Rate Loan and (ii)  three (3)  Eurodollar  Business  Days prior to the
     proposed  Drawdown Date of any Eurodollar  Rate Loan;  provided that at all
     times  during  the  continuance  of a  Default  or Event of  Default,  each
     telephonic  notice shall be confirmed in a writing in the form of Exhibit C
     hereto. Each such notice shall specify (A) the principal amount of the Loan
     requested,  (B) the proposed  Drawdown Date of such Loan,  (C) the Interest
     Period for such Loan and (D) the Type of such Loan.  Promptly  upon receipt
     of any such  notice,  the Agent shall  notify each of the Lenders  thereof.
     Each Loan Request shall be irrevocable and binding on each of the Borrowers
     and shall  obligate  the  Borrowers to accept the Loan  requested  from the
     Lenders on the proposed  Drawdown  Date.  Each Loan Request for  Eurodollar
     Rate  Loans  shall be in a minimum  aggregate  amount of  $1,000,000  or an
     integral  multiple  of  $100,000 in excess  thereof.  Unless the  Borrowers
     specifically  direct  the  Agent  in  writing  not to  accept  or act  upon
     telephonic or electronic Loan Requests from any Borrower, neither the Agent
     nor any Lender shall have any  liability to the  Borrowers  for any loss or
     damage  suffered by the  Borrowers  as a result of Agent's or any  Lender's
     honoring   any  Loan  Request   communicated   to  it   telephonically   or
     electronically  and purporting to have been sent to Agent or a Lender by an
     Authorized  Officer of any  Borrower,  and neither the Agent nor any Lender
     shall have any duty to verify the origin of any such  communication  or the
     authority of the Person sending it.

          2.6.2.  Swing  Line.  Notwithstanding  the notice and  minimum  amount
     requirements  set forth in ss.2.6.1 but  otherwise in  accordance  with the
     terms and conditions of this Credit  Agreement,  the Agent may, in its sole
     discretion  and  without  conferring  with the  Lenders,  make Loans to the
     Borrowers (i) by entry of credits to Century  Aluminum's  operating account
     (No.  563-90229) or any other  account(s) of the Borrowers (the  "Operating
     Accounts")  with the  Agent or its  Affiliates  to  cover  checks  or other
     charges  which  the  applicable  Borrower  has drawn or made  against  such
     account or (ii) in an amount as otherwise  requested by the Borrowers.  The
     Borrowers  hereby request and authorize the Agent to make from time to time
     such Loans by means of  appropriate  entries of such credits  sufficient to
     cover checks and other charges then presented for payment from an Operating
     Account  or  as  otherwise  so  requested.  The  Agent  and  the  Borrowers
     acknowledge and agree that the making of such Loans shall, in each case, be
     subject in all respects to the  provisions  of this Credit  Agreement as if
     they were Loans covered by a Loan Request (other than the  requirement  for
     an immediate Settlement) including, without limitation, the limitations set
     forth in ss.2.1 and the  requirements  that the  applicable  provisions  of
     ss.11  (in the  case of  Loans  made on the  Closing  Date)  and  ss.12  be
     satisfied.  All actions  taken by the Agent  pursuant to the  provisions of
     this  ss.2.6.2  shall be  conclusive  and binding on the  Borrowers and the
     Lenders absent the Agent's gross  negligence or willful  misconduct.  Loans
     made pursuant to this ss.2.6.2 shall be Base Rate Loans until  converted in
     accordance  with the  provisions of the Credit  Agreement  and,  prior to a
     Settlement, such interest shall be for the account of the Agent.


                                      -28-


     2.7. Conversion Options.

          2.7.1.  Conversion to Different  Type of Loan. The Borrowers may elect
     from time to time to  convert  any  outstanding  Loan to a Loan of  another
     Type, provided that (i) with respect to any such conversion of a Eurodollar
     Rate Loan to a Base Rate Loan, the Borrowers  shall give the Agent at least
     one (1)  Business  Day prior  written  notice of such  election;  (ii) with
     respect to any such  conversion  of a Base Rate Loan to a  Eurodollar  Rate
     Loan,  the  Borrowers  shall give the Agent at least  three (3)  Eurodollar
     Business Days prior written notice of such election;  (iii) with respect to
     any such  conversion of a Eurodollar  Rate Loan into a Base Rate Loan, such
     conversion  shall only be made on the last day of the Interest  Period with
     respect  thereto and (iv) no Loan may be converted  into a Eurodollar  Rate
     Loan when any Default or Event of Default has occurred  and is  continuing.
     On the date on which such  conversion  is being made each Lender shall take
     such action as is necessary to transfer its  Commitment  Percentage of such
     Loans to its Domestic Lending Office or its Eurodollar  Lending Office,  as
     the case may be.  All or any part of  outstanding  Loans of any Type may be
     converted into a Loan of another Type as provided herein, provided that any
     partial  conversion  shall be in a minimum  aggregate  principal  amount of
     $1,000,000  or an integral  multiple of  $100,000 in excess  thereof.  Each
     Conversion Request relating to the conversion of a Revolving Credit Loan to
     a Eurodollar Rate Loan shall be irrevocable by the Borrowers.

          2.7.2.  Continuation  of Type of  Loan.  Any  Loan of any  Type may be
     continued  as a Loan of the same Type upon the  expiration  of an  Interest
     Period with respect  thereto by compliance by the Borrowers with the notice
     provisions contained in ss.2.7.1; provided that no Eurodollar Rate Loan may
     be  continued as such when any Default or Event of Default has occurred and
     is continuing,  and during any Default or Event of Default  Eurodollar Rate
     Loans shall be automatically  converted to a Base Rate Loan on the last day
     of the first Interest Period relating thereto ending during the continuance
     of any Default or Event of Default of which  officers  of the Agent  active
     upon the Borrowers'  account have actual  knowledge.  In the event that the
     Borrowers fail to provide any such notice with respect to the  continuation
     of any Eurodollar  Rate Loan as such,  then such Eurodollar Rate Loan shall
     be automatically converted to a Base Rate Loan on the last day of the first
     Interest  Period relating  thereto.  The Agent shall notify the Lenders and
     the Borrowers promptly when any such automatic  conversion  contemplated by
     this ss.2.7 is scheduled to occur.

          2.7.3.  Eurodollar  Rate Loans.  Any conversion to or from  Eurodollar
     Rate Loans shall be in such amounts and be made pursuant to such  elections
     so that, after giving effect thereto, (a) the aggregate principal amount of
     all Eurodollar Rate Loans having the same Interest Period shall not be less
     than  $1,000,000 or an integral  multiple of $100,000 in excess thereof and
     (b) no more than five (5) Eurodollar Rate Loans shall be outstanding at any
     time.


                                      -29-


     2.8. Funds for Loan.

          2.8.1.  Funding  Procedures.   Not  later  than  2:00  p.m.  (Chicago,
     Illinois,  time) on the  proposed  Drawdown  Date of any Loan,  each of the
     Lenders will make available to the Agent, at the Agent's Payment Office, in
     immediately  available  funds,  the  amount  of  such  Lender's  Commitment
     Percentage  of the amount of the  requested  Loan.  Upon  receipt from each
     Lender of such  amount,  and upon  receipt  of the  documents  required  by
     ss.ss.11  and 12 and the  satisfaction  of the other  conditions  set forth
     therein,  to the extent  applicable,  the Agent will make  available to the
     Borrowers the aggregate  amount of such Loan made available to the Agent by
     the Lenders.  The failure or refusal of any Lender to make available to the
     Agent at the  aforesaid  time and place on any Drawdown  Date the amount of
     its Commitment Percentage of the requested Loan shall not relieve any other
     Lender from its several obligation hereunder to make available to the Agent
     the amount of such other  Lender's  Commitment  Percentage of any requested
     Loan.

          2.8.2.  Advances  by Agent.  The Agent  may,  unless  notified  to the
     contrary by any Lender  prior to a Drawdown  Date,  assume that such Lender
     has made  available to the Agent on such  Drawdown  Date the amount of such
     Lender's  Commitment  Percentage  of the Loans to be made on such  Drawdown
     Date, and the Agent may (but it shall not be required to), in reliance upon
     such assumption, make available to the Borrowers a corresponding amount. If
     any Lender  makes  available  to the Agent such amount on a date after such
     Drawdown Date, such Lender shall pay to the Agent on demand an amount equal
     to the product of (i) the average  computed  for the period  referred to in
     clause (iii) below, of the weighted average interest rate paid by the Agent
     for federal  funds  acquired by the Agent  during each day included in such
     period,  times (ii) the amount of such  Lender's  Commitment  Percentage of
     such Loans, times (iii) a fraction, the numerator of which is the number of
     days that elapse from and including such Drawdown Date to the date on which
     the amount of such  Lender's  Commitment  Percentage  of such  Loans  shall
     become immediately  available to the Agent, and the denominator of which is
     365. A statement of the Agent  submitted to such Lender with respect to any
     amounts  owing under this  paragraph  shall be prima facie  evidence of the
     amount  due and owing to the Agent by such  Lender.  If the  amount of such
     Lender's  Commitment  Percentage of such Loans is not made available to the
     Agent by such Lender within three (3) Business Days following such Drawdown
     Date, the Agent shall be entitled to recover such amount from the Borrowers
     on demand,  with interest  thereon at the rate per annum  applicable to the
     Loans made on such Drawdown Date.


                                      -30-


     2.9. Change in Borrowing Base.

          (a) The  Borrowing  Base shall be determined by the Agent by reference
     to  the  Borrowing  Base  Report  required  to  be  delivered  pursuant  to
     ss.8.4(f)(A).

          (b) The Agent may, in its  reasonable  discretion,  from time to time,
     reduce the  Borrowing  Base by such amounts  ("Reserves")  as the Agent may
     from time to time establish and revise (a) to reflect  events,  conditions,
     contingencies  or risks  which do or may  adversely  affect  either (A) any
     Collateral, the rights of the Agent or any of the Lenders in any Collateral
     or its value or (B) the security  interest and other rights of the Agent or
     any of  the  Lenders  in  the  Collateral  (including  the  enforceability,
     perfection and priority  thereof) or (b) to reflect the belief of the Agent
     that any  Borrowing  Base Report or other  collateral  report or  financial
     information  furnished by or on behalf of the Borrowers to the Agent or any
     of the Lenders is or may have been incomplete,  inaccurate or misleading in
     any  material  respect.  Reserves  may  include,  but are not  limited  to:
     reserves to reflect (a) an increase in the dilution of Accounts Receivable,
     (b) material  changes in the number of days turnover in inventory,  (c) the
     deterioration in any material respect of the liquidation value of inventory
     or a change in the mix of  inventory,  (d)  taxes  and  other  governmental
     charges, whether ad valorem,  personal property or otherwise and whether or
     not the tax claims  therefor may have  priority  over the Agent's  security
     interest in any of the Collateral,  (e) any customs, duty, freight or other
     out-of-pocket  costs or  expenses  required  or  advisable  to  "land"  any
     Eligible Inventory the purchase of which is supported by a Letter of Credit
     and (f) any offset  claims which an account  debtor has against any Account
     Receivable.

          (c) The Agent shall give to the Borrowers written notice of any change
     in the  Borrowing  Base  determined  by the  Agent.  Such  notice  shall be
     effective  immediately  upon its receipt by the Borrowers.  Notwithstanding
     anything  contained  in  this  Agreement  to the  contrary,  it  shall  not
     constitute  an Event of Default  (but shall  constitute  a Default)  to the
     extent  that the  Loans,  and all  Letter of Credit  Exposure  exceeds  the
     Borrowing Base as adjusted pursuant to this Section 2.9 until five (5) days
     after the Borrowers receipt of notice of such change in the Borrowing Base.

     2.10. Settlements.

          2.10.1.  General.  On each Settlement Date, the Agent shall, not later
     than 12:00 noon (Chicago,  Illinois,  time),  give  telephonic or facsimile
     notice (i) to the Lenders and the Borrowers of the  respective  outstanding
     amount  of  Loans  made by the  Agent on  behalf  of the  Lenders  from the
     immediately  preceding Settlement Date through the close of business on the
     prior day and the amount of any Eurodollar Rate Loans to be made (following
     the giving of notice pursuant to  ss.2.6.1(ii))  on such date pursuant to a
     Loan Request and (ii) to the Lenders of the amount (a "Settlement  Amount")
     that each Lender (a "Settling  Lender") shall pay to effect a Settlement of
     any  Loan.  A  statement  of the Agent  submitted  to the  Lenders  and the
     Borrowers or to the Lenders  with  respect to any amounts  owing under this
     ss.2.10  shall be prima facie  evidence  of the amount due and owing.  Each
     Settling Lender shall, not later than 2:00 p.m. (Chicago,  Illinois,  time)
     on such Settlement  Date,  effect a wire transfer of immediately  available
     funds to the Agent in the amount of the Settlement Amount for such Settling
     Lender.  All funds advanced by any Lender as a Settling  Lender pursuant to
     this  ss.2.10  shall for all  purposes  be  treated  as a Loan made by such
     Settling  Lender to the  applicable  Borrower and all funds received by any


                                      -31-


     Lender  pursuant  to this  ss.2.10  shall for all  purposes  be  treated as
     repayment of amounts owed with respect to Loans made by such Lender. In the
     event that any  bankruptcy,  reorganization,  liquidation,  receivership or
     similar  cases or  proceedings  in which any of the  Borrowers are a debtor
     prevent a Settling  Lender from making any Loan to effect a  Settlement  as
     contemplated  hereby,  such Settling Lender will make such dispositions and
     arrangements  with the other Lenders with respect to such Loans,  either by
     way of purchase of  participations,  distribution,  pro tanto assignment of
     claims,  subrogation or otherwise as shall result in each Lender's share of
     the  outstanding  Loans being equal,  as nearly as may be, to such Lender's
     Commitment Percentage of the outstanding amount of the Loans.

          2.10.2.  Failure  to Make  Funds  Available.  The  Agent  may,  unless
     notified to the contrary by any Settling Lender prior to a Settlement Date,
     assume that such  Settling  Lender has made or will make  available  to the
     Agent  on  such  Settlement  Date  the  amount  of such  Settling  Lender's
     Settlement  Amount, and the Agent may (but it shall not be required to), in
     reliance upon such assumption,  make available to the applicable Borrower a
     corresponding  amount.  If any Settling Lender makes available to the Agent
     such amount on a date after such  Settlement  Date,  such  Settling  Lender
     shall pay to the Agent on demand an amount  equal to the product of (i) the
     average  computed for the period  referred to in clause (iii) below, of the
     weighted average interest rate paid by the Agent for federal funds acquired
     by the Agent during each day included in such period, times (ii) the amount
     of such Settlement Amount,  times (iii) a fraction,  the numerator of which
     is the number of days that elapse from and including such  Settlement  Date
     to the date on which the  amount of such  Settlement  Amount  shall  become
     immediately  available to the Agent, and the denominator of which is 360. A
     statement of the Agent  submitted to such  Settling  Lender with respect to
     any amounts owing under this ss.2.10.2 shall be prima facie evidence of the
     amount due and owing to the Agent by such Settling Lender. If such Settling
     Lender's  Settlement  Amount  is not made  available  to the  Agent by such
     Settling  Lender within three (3) Business Days following  such  Settlement
     Date,  the  Agent  shall  be  entitled  to  recover  such  amount  from the
     applicable  Borrower on demand, with interest thereon at the rate per annum
     applicable to the Loans as of such Settlement Date.

          2.10.3.  No Effect on Other  Lenders.  The  failure  or refusal of any
     Settling  Lender to make  available to the Agent at the aforesaid  time and
     place  on  any  Settlement  Date  the  amount  of  such  Settling  Lender's
     Settlement  Amount shall not (i) relieve any other Settling Lender from its
     several obligations  hereunder to make available to the Agent the amount of
     such other  Settling  Lender's  Settlement  Amount or (ii)  impose upon any
     Lender,  other  than the  Settling  Lender  so  failing  or  refusing,  any
     liability with respect to such failure or refusal or otherwise increase the
     Revolving Credit Commitment of such other Lender.

     2.11. Repayments of Revolving Credit Loans Prior to Event of Default.

          2.11.1.  Credit for Funds Received in Fleet Blocked Account.  Prior to
     the  occurrence of an Event of Default as to which the account  officers of
     the Agent active upon the Borrowers' account have actual knowledge, (i) all
     funds  and  cash  proceeds  in the form of  money,  checks  and like  items
     received in the Fleet Blocked  Account as  contemplated by ss.8.13 shall be
     credited,  on the same Business Day on which the Agent determines that good
     collected  funds  have been  received,  and,  prior to the  receipt of good
     collected  funds,  on a  provisional  basis  until  final  receipt  of good
     collected funds,  and applied as contemplated by ss.2.11.2,  (ii) all funds
     and cash  proceeds  in the form of a wire  transfer  received  in the Fleet
     Blocked  Account as  contemplated  by ss.8.13 shall be credited on the same
     Business  Day as the Agent's  receipt of such  amounts (or up to such later
     date as the Agent determines that good collected funds have been received),
     and  applied as  contemplated  by  ss.2.11.2,  and (iii) all funds and cash
     proceeds in the form of an automated  clearing house  transfer  received in
     the Fleet Blocked Account as contemplated by ss.8.13 shall be credited,  on
     the next Business Day following the Agent's  receipt of such amounts (or up
     to such later date as the Agent  determines  that good collected funds have
     been received),  and applied as contemplated by ss.2.11.2.  For purposes of
     the foregoing  provisions of this ss.2.11.1,  the Agent shall not be deemed
     to have received any such funds or cash proceeds on any day unless received
     by the Agent before 1:00 p.m. (Chicago,  Illinois,  time) on such day. Each
     of the Borrowers further  acknowledges and agrees that any such provisional
     credits or credits in respect of wire or  automatic  clearing  house  funds
     transfers shall be subject to reversal if final collection in good funds of
     the  related  item is not  received  by, or final  settlement  of the funds
     transfer is not made in favor of, the Agent in accordance  with the Agent's
     customary  procedures  and practices for  collecting  provisional  items or
     receiving settlement of funds transfers.

          2.11.2. Application of Payments Prior to Event of Default.

               (a) Prior to the  occurrence  of an Event of Default of which the
          account  officers of the Agent active on the  Borrowers'  account have
          knowledge,  all funds transferred to the Fleet Blocked Account and for
          which the  Borrowers  have  received  credits  shall be applied to the
          Obligations as follows:

                    (i) first,  to pay amounts  then due and payable  under this
               Credit Agreement, the Notes and the other Loan Documents;

                    (ii)  second,  to reduce  Loans  made by the Agent  pursuant
               to ss.2.6.2 and for which Settlement has not then been made;

                    (iii)  third,  to  reduce  other  Loans  which are Base Rate
               Loans;

                    (iv)  fourth,  to reduce  Loans  which are  Eurodollar  Rate
               Loans; and

                    (v) fifth,  except as otherwise  required by  ss.4.2(b)  and
               (c), to an Operating Account specified by Century Aluminum.

               (b) All  prepayments of Eurodollar Rate Loans prior to the end of
          an Interest  Period shall  obligate the  Borrowers to pay any Breakage
          Costs  associated  with such  Eurodollar Rate Loans in accordance with
          ss.5.11. Prior to the occurrence of an Event of Default, the Borrowers
          may elect to avoid such Breakage  Costs by having such funds placed in
          an Operating Account.


                                      -33-


               (c) All prepayments of the Loans pursuant to this ss.2.11.2 shall
          be allocated  among the Lenders making such Loans,  in proportion,  as
          nearly as practicable,  to the respective  unpaid  principal amount of
          such Loans outstanding,  with adjustments to the extent practicable to
          equalize any prior  payments or repayments  not exactly in proportion.
          Prior to any Settlement  Date,  however,  all prepayments of the Loans
          shall  be  applied  in  accordance  with  this  ss.2.11.2,   first  to
          outstanding Loans of the Agent.

     2.12. Repayments of Loans After Event of Default.  Following the occurrence
and during the continuance of an Event of Default of which the account  officers
of the  Agent  active  on the  Borrowers'  account  have  knowledge,  all  funds
transferred  to the Fleet  Blocked  Account  and for which  the  Borrowers  have
received credits shall be applied to the Obligations in accordance with ss.13.4.

                           3. REPAYMENT OF THE LOANS.

     3.1. Maturity. The Borrowers absolutely and unconditionally and jointly and
severally promise to pay on the Maturity Date, and there shall become absolutely
due and payable on the Maturity Date, all of the Loans outstanding on such date,
together with any and all accrued and unpaid  interest  thereon and all fees and
expenses  incurred  by the  Lenders and the Agent in  connection  therewith  and
payable by the Borrowers hereunder.

     3.2.  Mandatory  Repayments  of  Loans.  If at  any  time  the  sum  of the
outstanding  amount of the Loans,  and all Letter of Credit Exposure exceeds the
lesser of (i) the Total Revolving Credit Commitment and (ii) the Borrowing Base,
then the Borrowers shall  immediately pay the amount of such excess to the Agent
for the respective accounts of the Lenders for application: first, to any Unpaid
Reimbursement  Obligations;  second,  to the Loans; and third, to provide to the
Agent cash collateral for Reimbursement Obligations as contemplated by ss.4.2(b)
and (c). Each payment of any Unpaid  Reimbursement  Obligations or prepayment of
Loans  shall be  allocated  among  the  Lenders,  in  proportion,  as  nearly as
practicable,  to  each  Reimbursement  Obligation  or (as the  case  may be) the
respective  unpaid  principal  amount of each Lender's Note, with adjustments to
the extent  practicable to equalize any prior payments or repayments not exactly
in proportion.


                                      -34-


     3.3.  Optional  Repayments of Loans. The Borrowers shall have the right, at
their election,  to repay the outstanding  amount of the Loans, as a whole or in
part,  at any time without  penalty or premium (but subject to ss.5.11).  Except
for payments applied in accordance with ss.2.11.2,  the Borrowers shall give the
Agent,  no later than 11:00 a.m.,  Chicago,  Illinois,  time, at least three (3)
Business Days prior written notice of any proposed  prepayment  pursuant to this
ss.3.3 of Base Rate Loans,  and four (4) Eurodollar  Business Days notice of any
proposed  prepayment  pursuant to this ss.3.3 of Eurodollar  Rate Loans, in each
case  specifying  the proposed  date of  prepayment  of Loans and the  principal
amount to be prepaid.  Each such partial  prepayment of the Loans shall be in an
integral  multiple  of  $1,000,000  and  shall be  applied,  in the  absence  of
instruction by the Borrowers, first to the principal of Base Rate Loans and then
to the principal of Eurodollar Rate Loans,  at the Agent's option.  Each partial
prepayment  shall be allocated  among the Lenders,  in proportion,  as nearly as
practicable,  to the respective  unpaid  principal amount of each Lender's Note,
with adjustments to the extent  practicable to equalize any prior repayments not
exactly in proportion.

                              4. LETTERS OF CREDIT.

     4.1. Letter of Credit Commitments.

          4.1.1. Commitment to Issue Letters of Credit. Subject to the terms and
     conditions  hereof and the  execution  and  delivery by the  Borrowers of a
     letter  of credit  application  on the  Issuing  Bank's  customary  form (a
     "Letter of Credit Application"),  the Agent shall cause the Issuing Bank on
     behalf of the Lenders and in reliance upon the agreement of the Lenders set
     forth in  ss.4.1.4  and  upon the  representations  and  warranties  of the
     Borrowers  contained herein, in its individual  capacity,  to issue, extend
     and renew for the account of a Borrower one or more standby or  documentary
     letters of credit (individually, a "Letter of Credit"), in such form as may
     be requested from time to time by the applicable  Borrower and agreed to by
     the Issuing  Bank;  provided,  however,  that,  after giving effect to such
     request,  (a) the Letter of Credit Exposure shall not exceed $10,000,000 at
     any one time and (b) the sum of (i) the  Letter  of Credit  Exposure  plus,
     (ii) the amount of all Loans outstanding shall not exceed the lesser of (A)
     the Total Revolving Credit Commitment and (B) the Borrowing Base.

          4.1.2.   Letter  of  Credit   Applications.   Each  Letter  of  Credit
     Application  shall be completed to the satisfaction of the Issuing Bank. In
     the event that any provision of any Letter of Credit  Application  shall be
     inconsistent  with  any  provision  of  this  Credit  Agreement,  then  the
     provisions  of this  Credit  Agreement  shall,  to the  extent  of any such
     inconsistency, govern.

          4.1.3.  Terms of  Letters  of Credit.  Each  Letter of Credit  issued,
     extended or renewed  hereunder shall,  among other things,  (i) provide for
     the  payment  of sight  drafts  for  honor  thereunder  when  presented  in
     accordance  with the terms  thereof and when  accompanied  by the documents
     described therein, and (ii) have an expiry date no later than 365 days from
     the date of issuance  and a final expiry date no later than  fourteen  (14)
     days (or, if the Letter of Credit is  confirmed by a confirmer or otherwise
     provides for one or more nominated persons,  forty-five (45) days) prior to
     the  Maturity  Date.  Each Letter of Credit so issued,  extended or renewed
     shall be subject to the Uniform Customs or, in the case of a standby Letter
     of  Credit,  either  the  Uniform  Customs  or  the  International  Standby
     Practices.


                                      -35-


          4.1.4.  Reimbursement  Obligations of Lenders.  Each Lender  severally
     agrees that it shall be absolutely liable, without regard to the occurrence
     of any  Default  or Event  of  Default  or any  other  condition  precedent
     whatsoever,  to the  extent  of such  Lender's  Commitment  Percentage,  to
     reimburse  the  Agent as issuer of the  Letter  of Credit  Guaranty  or, as
     applicable,  the Issuing  Bank, on demand for the amount of each draft paid
     by the  Issuing  Bank under each  Letter of Credit to the extent  that such
     amount  is not  reimbursed  by  the  Borrowers  pursuant  to  ss.4.2  (such
     agreement   for  a  Lender  being  called  herein  the  "Letter  of  Credit
     Participation" of such Lender).

          4.1.5.  Participations of Lenders.  Each such payment made by a Lender
     shall be treated as the purchase by such Lender of a participating interest
     in the Borrowers'  Reimbursement Obligation under ss.4.2 in an amount equal
     to  such  payment.   Each  Lender  shall  share  in  accordance   with  its
     participating interest in any interest which accrues pursuant to ss.4.2.

     4.2.  Reimbursement  Obligation  of the  Borrowers.  In order to induce the
Agent to issue the Letter of Credit  Guaranty,  and the  Issuing  Bank to issue,
extend and renew each Letter of Credit and the Lenders to  participate  therein,
each Borrower  hereby  jointly and  severally  agrees to reimburse or pay to the
Agent or, as applicable the Issuing Bank, for the account of the Agent,  Issuing
Bank or (as the case may be) the Lenders,  with respect to each Letter of Credit
issued, extended or renewed by the Issuing Bank hereunder,

          (a) except as otherwise  expressly  provided in ss.4.2(b)  and (c), on
     each date that any draft  presented  under such Letter of Credit is honored
     by the Issuing  Bank,  or the Issuing Bank  otherwise  makes a payment with
     respect  thereto,  (i) the amount  paid by the  Issuing  Bank under or with
     respect to such Letter of Credit,  and (ii) the amount of any taxes,  fees,
     charges or other costs and expenses whatsoever incurred by the Issuing Bank
     or any Lender in  connection  with any payment  made by the Issuing Bank or
     any Lender under, or with respect to, such Letter of Credit,

          (b) upon the reduction (but not  termination)  of the Total  Revolving
     Credit  Commitment to an amount less than the Maximum  Drawing  Amount,  an
     amount equal to such difference,  which amount shall be held by the Issuing
     Bank or by the Agent for the benefit of the  Lenders,  the Issuing Bank and
     the Agent as cash collateral for all Reimbursement Obligations, and

          (c) upon the termination of the Total Revolving Credit Commitment,  or
     the  acceleration  of the  Reimbursement  Obligations  with  respect to all
     Letters of Credit in  accordance  with ss.13,  an amount  equal to the then
     Maximum Drawing Amount on all Letters of Credit, which amount shall be held
     by the  Issuing  Bank or by the Agent for the benefit of the  Lenders,  the
     Issuing  Bank  and the  Agent  as  cash  collateral  for all  Reimbursement
     Obligations.


                                      -36-


Each such payment shall be made to the Issuing Bank at the Issuing Bank's Letter
of Credit Office in immediately available funds. Interest on any and all amounts
remaining  unpaid by the  Borrower  under this  ss.4.2 at any time from the date
such  amounts  become due and  payable  (whether  as stated in this  ss.4.2,  by
acceleration  or  otherwise)  until  payment  in full  (whether  before or after
judgment)  shall be payable to the Issuing Bank on demand at the rate  specified
in ss.5.12 for overdue principal on the Revolving Credit Loans.

     4.3.  Letter of Credit  Payments.  If any draft shall be presented or other
demand for payment  shall be made under any Letter of Credit,  the Issuing  Bank
shall  notify the  Borrowers  of the date and amount of the draft  presented  or
demand for payment and of the date and time when it expects to pay such draft or
honor such demand for payment.  If the Borrowers  fails to reimburse the Issuing
Bank as  provided  in ss.4.2 on or  before  the date that such  draft is paid or
other  payment is made by the Issuing  Bank,  the  Issuing  Bank may at any time
thereafter  notify the  Lenders of the amount of any such  Unpaid  Reimbursement
Obligation.  No later  than 3:00 p.m.  (Boston  time) on the  Business  Day next
following  the receipt of such notice,  each Lender shall make  available to the
Agent, at the Agent's  Payment  Office,  in immediately  available  funds,  such
Lender's Commitment Percentage of such Unpaid Reimbursement Obligation, together
with an amount equal to the product of (i) the average,  computed for the period
referred to in clause (iii) below, of the weighted average interest rate paid by
the Issuing Bank for federal funds  acquired by the Issuing Bank during each day
included in such period, times (ii) the amount equal to such Lender's Commitment
Percentage of such Unpaid Reimbursement Obligation,  times (iii) a fraction, the
numerator of which is the number of days that elapse from and including the date
the Issuing Bank paid the draft presented for honor or otherwise made payment to
the  date  on  which  such  Lender's   Commitment   Percentage  of  such  Unpaid
Reimbursement obligation shall become immediately available to the Issuing Bank,
and the  denominator  of which is 360. The  responsibility  of the Agent and the
Issuing Bank to the Borrower and the Lenders shall be only to determine that the
documents  (including  each  draft)  delivered  under  each  Letter of Credit in
connection with such presentment shall be in conformity in all material respects
with such Letter of Credit.

     4.4.  Obligations  Absolute.  Each Borrower's  obligations  under this ss.4
shall be joint and  several and  absolute  and  unconditional  under any and all
circumstances  and  irrespective  of the  occurrence  of any Default or Event of
Default or any condition  precedent  whatsoever or any setoff,  counterclaim  or
defense to payment  which any  Borrower may have or have had against the Issuing
Bank, the Agent any Lender or any beneficiary of a Letter of Credit. Each of the
Borrowers  further  agrees with the Issuing Bank, the Agent and the Lenders that
the Issuing Bank,  the Agent and the Lenders shall not be  responsible  for, and
the Borrowers' Reimbursement  Obligations under ss.4.2 shall not be affected by,
among  other  things,  the  validity  or  genuineness  of  documents  or of  any
endorsements  thereon,  even if such documents should in fact prove to be in any
or all respects  invalid,  fraudulent or forged, or any dispute between or among
the  Borrowers,  the  beneficiary  of any  Letter  of  Credit  or any  financing
institution  or other party to which any Letter of Credit may be  transferred or
any claims or defenses  whatsoever of the Borrowers  against the  beneficiary of
any Letter of Credit or any such transferee. The Issuing Bank, the Agent and the
Lenders shall not be liable for any error,  omission,  interruption  or delay in
transmission,   dispatch  or   delivery  of  any  message  or  advice,   however
transmitted,  in connection with any Letter of Credit. Each Borrower agrees that
any action taken or omitted by the Issuing  Bank,  the Agent or any Lender under
or in  connection  with  each  Letter  of  Credit  and the  related  drafts  and
documents,  if done in good faith,  shall be binding upon each of the  Borrowers
and shall not result in any liability on the part of the Issuing Bank, the Agent
or any  Lender  to any of the  Borrowers.  Notwithstanding  the  foregoing,  the
Borrowers shall have no obligation hereunder to any Person indemnified hereunder
with respect to liabilities arising solely from such indemnified  Person's gross
negligence or willful misconduct.


                                      -37-


     4.5. Reliance by Issuer.  To the extent not inconsistent  with ss.4.4,  the
Issuing  Bank and the  Agent  shall be  entitled  to  rely,  and  shall be fully
protected in relying upon,  any Letter of Credit,  draft,  writing,  resolution,
notice, consent, certificate,  affidavit, letter, cablegram, telegram, telecopy,
telex or teletype message,  statement, order or other document believed by it to
be  genuine  and  correct  and to have been  signed,  sent or made by the proper
Person or Persons and upon advice and statements of legal  counsel,  independent
accountants  and other experts  selected by the Issuing Bank and the Agent.  The
Issuing  Bank and the Agent shall be fully  justified  in failing or refusing to
take any action under this Credit  Agreement unless it shall first have received
such  advice or  concurrence  of the  Majority  Lenders as it  reasonably  deems
appropriate or it shall first be indemnified to its reasonable  satisfaction  by
the Lenders  against any and all  liability and expense which may be incurred by
it by reason of taking or continuing  to take any such action.  The Issuing Bank
and the Agent shall in all cases be fully protected in acting,  or in refraining
from acting,  under this Credit  Agreement in  accordance  with a request of the
Majority  Lenders,  and such  request  and any  action  taken or  failure to act
pursuant thereto shall be binding upon the Lenders and all future holders of the
Notes or of a Letter of Credit Participation.

     4.6.  Letter of Credit Fee. The Borrowers  shall pay to the Agent a fee (in
each  case,  a "Letter  of Credit  Fee") in  respect of Letters of Credit on the
average  daily  Maximum  Drawing  Amount at a rate per  annum  equal to (a) with
respect to each standby Letter of Credit,  the Applicable  Margin for Eurodollar
Rate Loans per annum from time to time  applicable  and (b) with respect to each
documentary  Letter of Credit,  the Applicable  Margin for Eurodollar Rate Loans
per annum from time to time  applicable  minus  one-half of one percent  (1/2%),
such Letter of Credit Fees being  payable  quarterly in arrears on the first day
of each calendar  quarter and on the Maturity  Date. A portion of such Letter of
Credit  Fees equal to  one-quarter  of one  percent  (1/4%)  per annum  shall be
payable to the Agent for its own  account  and the  remainder  of such Letter of
Credit  Fees  shall be  payable  to the Agent for the  ratable  accounts  of the
Lenders  in  accordance  with  their  respective  Commitment  Percentages.   The
Borrowers  shall  also pay to the  Issuing  Bank,  at such time or times as such
charges are customarily  made by the Issuing Bank, the Issuing Bank's  customary
issuance  fees or  amendment  fees,  as the case may be, and the Issuing  Bank's
customary time negotiation fees per document examination or other administrative
fees.


                                      -38-


                         5. CERTAIN GENERAL PROVISIONS.

     5.1.  Closing Fee. The  Borrowers  agree to pay to the Agent on the Closing
Date a closing fee (the "Closing Fee") in the amounts and at the times set forth
in the Commitment Letter and Fee Letter.

     5.2. Agent's Fee. The Borrowers shall pay to the Agent, for the Agent's own
account,  an Agent's fee (the "Agent's Fee") in the amounts and at the times set
forth in the Commitment Letter and Fee Letter

     5.3. Funds for Payments.

          5.3.1.  Payments  to  Agent.  All  payments  of  principal,  interest,
     Reimbursement  Obligations,  Fees and any other  amounts due  hereunder  or
     under any of the other Loan Documents shall be made on the due date thereof
     to the Agent in Dollars, for the respective accounts of the Lenders and the
     Agent,  at the Agent's Payment Office or at such other place that the Agent
     may  from  time to time  designate,  in each  case at or about  12:00  p.m.
     (Chicago,  Illinois,  time or other local time at the place of payment) and
     in immediately available funds.

          5.3.2.  No Offset,  etc. All payments by the  Borrowers  hereunder and
     under any of the other Loan  Documents  shall be made  without  recoupment,
     setoff or counterclaim and free and clear of and without  deduction for any
     taxes, levies, imposts,  duties,  charges, fees, deductions,  withholdings,
     compulsory loans, restrictions or conditions of any nature now or hereafter
     imposed or levied by any jurisdiction or any political  subdivision thereof
     or taxing or other authority  therein unless the Borrowers are compelled by
     law to make  such  deduction  or  withholding.  If any such  obligation  is
     imposed  upon the  Borrowers  with  respect  to any  amount  payable  by it
     hereunder or under any of the other Loan Documents,  the Borrowers will pay
     to the Agent,  for the  account of the  Lenders or (as the case may be) the
     Agent,  on the date on which such  amount is due and payable  hereunder  or
     under such other Loan Document,  such additional amount in Dollars as shall
     be  necessary  to enable the  Lenders or the Agent to receive  the same net
     amount which the Lenders or the Agent would have  received on such due date
     had no such obligation been imposed upon the Borrowers.  The Borrowers will
     deliver promptly to the Agent  certificates or other valid vouchers for all
     taxes or other charges  deducted from or paid with respect to payments made
     by the Borrowers hereunder or under such other Loan Document.


                                      -39-


     5.4. Computations.  All computations of interest on (a) Base Rate Loans and
of Commitment  Fees or other fees shall,  unless  otherwise  expressly  provided
herein,  be based on a 365-day  year (or 366-day  year,  as the case may be) and
paid for the actual number of days elapsed,  and (b)  Eurodollar  Rate Loans and
Letter of Credit Fees shall,  unless otherwise  expressly  provided  herein,  be
based on a 360-day year.  Except as otherwise  provided in the definition of the
term "Interest Period" with respect to Eurodollar Rate Loans, whenever a payment
hereunder or under any of the other Loan Documents  becomes due on a day that is
not a Business  Day, the due date for such payment shall be extended to the next
succeeding  Business Day, and interest shall accrue during such  extension.  The
outstanding  amount of the Loans as  reflected  on the Note Records from time to
time shall be considered  correct and binding on the Borrowers unless within ten
(10)  Business  Days  after  receipt  of any  notice  by the Agent or any of the
Lenders of such  outstanding  amount,  the Agent or such Lender shall notify the
Borrower to the contrary.

     5.5.  Inability to Determine  Eurodollar  Rate. In the event,  prior to the
commencement  of any Interest  Period  relating to any Eurodollar Rate Loan, the
Agent shall  determine or be notified by the Majority  Lenders that adequate and
reasonable  methods do not exist for ascertaining the Eurodollar Rate that would
otherwise determine the rate of interest to be applicable to any Eurodollar Rate
Loan during any Interest  Period,  the Agent shall forthwith give notice of such
determination  (which shall be  conclusive  and binding on the Borrowers and the
Lenders) to the Borrowers and the Lenders. In such event (i) any Loan Request or
Conversion  Request with respect to Eurodollar Rate Loans shall be automatically
withdrawn  and  shall be  deemed  a  request  for Base  Rate  Loans,  (ii)  each
Eurodollar  Rate Loan will  automatically,  on the last day of the then  current
Interest  Period  relating  thereto,  become a Base  Rate  Loan,  and  (iii) the
obligations  of the Lenders to make  Eurodollar  Rate Loans  shall be  suspended
until the Agent or the Majority Lenders determine that the circumstances  giving
rise to such suspension no longer exist, whereupon the Agent or, as the case may
be, the Agent upon the instruction of the Majority Lenders,  shall so notify the
Borrowers and the Lenders.

     5.6.  Illegality.  Notwithstanding  any  other  provisions  herein,  if any
present or future law, regulation,  treaty or directive or in the interpretation
or application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar  Rate  Loans,  such  Lender  shall  forthwith  give  notice  of  such
circumstances  to the  Borrowers  and the other  Lenders and  thereupon  (i) the
commitment  of such  Lender to make  Eurodollar  Rate Loans or convert  Loans of
another Type to Eurodollar Rate Loans shall forthwith be suspended and (ii) such
Lender's  Loans then  outstanding  as Eurodollar  Rate Loans,  if any,  shall be
converted  automatically  to Base  Rate  Loans on the last day of each  Interest
Period applicable to such Eurodollar Rate Loans or within such earlier period as
may be required by law. The Borrowers hereby agree promptly to pay the Agent for
the account of such Lender,  upon demand by such Lender,  any additional amounts
necessary  to  compensate  such Lender for any costs  incurred by such Lender in
making any conversion in accordance with this ss.5.6,  including any interest or
fees payable by such Lender to lenders of funds  obtained by it in order to make
or maintain its Eurodollar Rate Loans hereunder.


                                      -40-


     5.7.  Additional Costs, etc. If any present or future Applicable Law, which
expression,  as used herein, includes statutes, rules and regulations thereunder
and  interpretations  thereof by any competent  court or by any  governmental or
other  regulatory  body or  official  charged  with  the  administration  or the
interpretation thereof and requests, directives, instructions and notices at any
time or from time to time hereafter made upon or otherwise  issued to any Lender
or the Agent by any central bank or other  fiscal,  monetary or other  authority
(whether or not having the force of law), shall:

          (a) subject any Lender or the Agent to any tax,  levy,  impost,  duty,
     charge,  fee,  deduction or  withholding of any nature with respect to this
     Credit  Agreement,  the other Loan Documents,  any Letters of Credit,  such
     Lender's  Revolving  Credit  Commitment or the Loans (other than  franchise
     taxes or taxes  based  upon or  measured  by the  income or profits of such
     Lender or the Agent), or

          (b)  materially  change the basis of  taxation  (except for changes in
     franchise taxes or taxes on income or profits) of payments to any Lender of
     the principal of or the interest on any Loans or any other amounts  payable
     to any Lender or the Agent under this Credit  Agreement or any of the other
     Loan Documents, or

          (c) impose or increase or render  applicable (other than to the extent
     specifically  provided for elsewhere in this Credit  Agreement) any special
     deposit, reserve, assessment,  liquidity, capital adequacy or other similar
     requirements  (whether or not having the force of law) against  assets held
     by, or deposits in or for the account of, or loans by, or letters of credit
     issued by, or commitments of an office of any Lender, or

          (d)  impose  on any  Lender  or the  Agent  any  other  conditions  or
     requirements  with  respect  to  this  Credit  Agreement,  the  other  Loan
     Documents, any Letters of Credit, the Loans, such Lender's Revolving Credit
     Commitment,  or any class of loans,  letters  of credit or  commitments  of
     which any of the Loans or such Lender's  Commitments  forms a part, and the
     result of any of the foregoing is

               (i) to  increase  the  cost to any  Lender  of  making,  funding,
          issuing,  renewing,  extending or maintaining any of the Loans or such
          Lender's Revolving Credit Commitment or any Letter of Credit, or

               (ii) to reduce the amount of principal,  interest,  Reimbursement
          Obligation  or  other  amount  payable  to such  Lender  or the  Agent
          hereunder on account of such Lender's Revolving Credit Commitment, any
          Letter of Credit or any of the Loans, or

               (iii) to require  such Lender or the Agent to make any payment or
          to  forego  any  interest  or  Reimbursement  Obligation  or other sum
          payable hereunder, the amount of which payment or foregone interest or
          Reimbursement  Obligation  or other sum is  calculated by reference to
          the gross  amount of any sum  receivable  or deemed  received  by such
          Lender or the Agent from the Borrowers hereunder,


                                      -41-


then, and in each such case, the Borrowers will, upon demand made by such Lender
or (as the case may be) the Agent at any time and from time to time and as often
as the  occasion  therefor  may  arise,  pay to such  Lender or the  Agent  such
additional  amounts as will be sufficient to compensate such Lender or the Agent
for  such  additional  cost,   reduction,   payment  or  foregone   interest  or
Reimbursement Obligation or other sum.

     5.8.  Capital  Adequacy.  If after the date  hereof any Lender or the Agent
determines  that (i) the  adoption of or change in any law,  governmental  rule,
regulation,  policy,  guideline or directive (whether or not having the force of
law) regarding  capital  requirements for banks or bank holding companies or any
change in the  interpretation or application  thereof by a court or Governmental
Authority with  appropriate  jurisdiction,  or (ii) compliance by such Lender or
the Agent or any corporation  controlling such Lender or the Agent with any law,
governmental rule,  regulation,  policy,  guideline or directive (whether or not
having the force of law) of any such entity regarding capital adequacy,  has the
effect of reducing the return on such  Lender's or the Agent's  commitment  with
respect to any Loans to a level  below that which such Lender or the Agent could
have  achieved  but  for  such  adoption,  change  or  compliance  (taking  into
consideration  such Lender's or the Agent's then existing  policies with respect
to capital adequacy and assuming full  utilization of such entity's  capital) by
any  amount  deemed  by such  Lender  or (as the  case  may be) the  Agent to be
material, then such Lender or the Agent may notify the Borrower of such fact. To
the  extent  that the amount of such  reduction  in the return on capital is not
reflected in the Base Rate,  the  Borrowers  agree to pay such Lender or (as the
case may be) the Agent for the amount of such reduction in the return on capital
as and when such reduction is determined upon presentation by such Lender or (as
the case may be) the Agent of a certificate in accordance  with ss.5.10  hereof.
Each Lender shall allocate such cost increases among its customers in good faith
and on an equitable basis.

     5.9. Change of Lending Office. Each Lender agrees that, upon the occurrence
of any event  giving rise to the  operation  of ss.ss.5.7 or 5.8 with respect to
such Lender,  it will, if requested by the  Borrowers,  use  reasonable  efforts
(subject to overall policy  consideration  of such Lender) to designate  another
lending  office  for any  Loans  affected  by such  event,  provided  that  such
designation is made on such terms that such Lender and its lending office suffer
no economic, legal or regulatory  disadvantage,  with the object of avoiding the
consequence  of the event  giving  rise to the  operation  of any such  Section.
Nothing in this ss.5.9 shall affect or postpone  any of the  obligations  of the
Borrowers or the right of any Lender provided in ss.ss.5.7 or 5.8.


                                      -42-


     5.10.  Certificate.  A  certificate  setting forth any  additional  amounts
payable  pursuant to ss.ss.5.7 or 5.8 and an  explanation  of such amounts which
are  due,  submitted  by any  Lender  or the  Agent to the  Borrowers,  shall be
conclusive, absent manifest error, that such amounts are due and owing.

     5.11. Indemnity.  Each Borrower agrees to indemnify each Lender and to hold
each Lender harmless from and against any loss,  cost or expense  (collectively,
"Breakage  Costs") that such Lender may sustain or incur as a consequence of (i)
default by the Borrowers in payment of the  principal  amount of or any interest
on any  Eurodollar  Rate Loans as and when due and payable,  including  any such
loss or expense  arising from interest or fees payable by such Lender to lenders
of funds  obtained by it in order to maintain its  Eurodollar  Rate Loans,  (ii)
default by the Borrowers in making a borrowing or conversion after the Borrowers
have given (or are deemed to have given) a Loan Request,  notice or a Conversion
Request relating thereto in accordance with ss.2.6 or ss.2.7 or (iii) the making
of any payment of a Eurodollar  Rate Loan or the making of any conversion of any
such  Loan  to a Base  Rate  Loan  on a day  that  is not  the  last  day of the
applicable  Interest  Period with respect  thereto,  including  interest or fees
payable by such  Lender to lenders of funds  obtained by it in order to maintain
any such Loans.

     5.12. Interest After Default.

          5.12.1.  Overdue  Amounts.   Overdue  principal  and  (to  the  extent
     permitted by  Applicable  Law)  interest on the Loans and all other overdue
     amounts  payable  hereunder or under any of the other Loan Documents  shall

System.

     5.15. Concerning Joint and Several Liability of the Borrowers

          (a) Each of the  Borrowers  is accepting  joint and several  liability
     hereunder in consideration of the financial  accommodations  to be provided
     by the Agent, the Issuing Bank and the Lenders under this Credit Agreement,
     for the mutual benefit,  directly and indirectly,  of each of the Borrowers
     and in consideration of the undertakings of each of the Borrowers to accept
     joint and several liability for the obligations of each of them.

          (b) Each of the Borrowers,  jointly and severally,  hereby irrevocably
     and  unconditionally  accepts,  not  merely  as  a  surety  but  also  as a
     co-debtor,  joint and  several  liability  with each other  Borrower,  with
     respect to the payment and performance of all of the Obligations,  it being
     the intention of the parties hereto that all the  Obligations  shall be the
     joint and several  obligations of all of the Borrowers without  preferences
     or distinction among them.

          (c) If and to the extent that any of the Borrowers  shall fail to make
     any payment  with respect to any of the  Obligations  as and when due or to
     perform any of such Obligations in accordance with the terms thereof,  then
     in each such event each other  Borrower will make such payment with respect
     to, or perform, such Obligation.

          (d) The  obligations  of each  Borrower  under the  provisions of this
     ss.5.15  constitute  the absolute  and  unconditional  obligations  of such
     Borrower  enforceable  against it to the full  extent  permitted  under the
     terms hereof, irrespective of the validity, regularity or enforceability of
     this Credit Agreement or any other circumstance whatsoever.

          (e) Except as otherwise  expressly provided for herein,  each Borrower
     hereby  waives  notice of  acceptance  of its joint and several  liability,
     notice  of the  Loans  made  under  this  Credit  Agreement,  notice of the
     occurrence  of any  Default or Event of  Default,  or of any demand for any
     payment under this Credit Agreement, notice of any action at any time taken
     or  omitted by the  Agent,  the  Issuing  Bank or the  Lenders  under or in
     respect of any of the  Obligations,  any  requirement  of  diligence  or to
     mitigate damages and, generally, all demands, notices and other formalities
     of every kind in  connection  with this  Credit  Agreement.  Each  Borrower
     hereby assents to, and waives notice of, any extension or  postponement  of
     the time for the payment of any of the  Obligations,  the acceptance of any
     partial  payment   thereon,   any  waiver,   consent  or  other  action  or
     acquiescence  by the Agent,  the Issuing Bank or the Lenders at any time or
     times in  respect of any  default by any  Borrowers  or  Guarantors  in the
     performance or satisfaction of any term,  covenant,  condition or provision
     of this Credit Agreement,  any and all other indulgences  whatsoever by the
     Agent, the Issuing Bank or the Lenders in respect of any of the obligations
     hereunder, and the taking,  addition,  substitution or release, in whole or
     in part, at any time or times, of any security for any of such  obligations
     or the  addition,  substitution  or  release,  in whole or in part,  of any
     Borrower  or  any  Guarantor.   Without  limiting  the  generality  of  the
     foregoing,  each Borrower assents to any other action or delay in acting or
     failure to act on the part of the Agent,  the  Issuing  Bank or the Lenders
     including, without limitation, any failure strictly or diligently to assert
     any right or to pursue any remedy or to comply fully with  Applicable  Laws
     thereunder,  which might,  but for the  provisions of this ss.5.15,  afford
     grounds for terminating,  discharging or relieving such Borrower,  in whole
     or in part,  from any of its Obligations  under this ss.5.15,  it being the
     intention of each Borrower that, so long as any of the  Obligations  remain
     unsatisfied,  the Obligations of such Borrower under this ss.5.15 shall not
     be  discharged  except by  performance  and then only to the extent of such
     performance.  Except as otherwise  expressly provided for herein, the joint
     and several  liability of the Borrowers  hereunder  shall  continue in full
     force and effect  notwithstanding any absorption,  merger,  amalgamation or
     any other change whatsoever in the name, membership,  constitution or place
     of formation of any Borrower or the Agent, the Issuing Bank or the Lenders.
     If at any time, any payment, or any part thereof, made in respect of any of
     the Obligations,  is rescinded or must otherwise be restored or returned by
     the Agent, the Issuing Bank or the Lenders upon the insolvency,  bankruptcy
     or reorganization of any of the Borrowers or Guarantors,  or otherwise, the
     provisions  of this ss.5.15  will  forthwith be  reinstated  in effect,  as
     though such payment had not been made.


                                      -44-


     5.16. Replacement of Lender.

          (a) In the event that any  Lender  makes a demand  for  payment  under
     ss.5.7 or  ss.5.8 or  notifies  the  Agent of any  circumstances  requiring
     payment  pursuant to ss.5.6 or if the  Borrowers  are  required to make any
     payment to the Lender  pursuant to ss.5.3.2,  the  Borrowers may within 120
     days of such demand,  if no Default or Event of Default  then  exists,  (i)
     reduce the Total Revolving  Credit  Commitment,  in the full amount of such
     Lender's Commitment Percentage of the Total Revolving Credit Commitment and
     repay such  Lender in full or (ii)  replace  such  Lender  with an Eligible
     Assignee in accordance with ss.19.1  (including  execution of an Assignment
     and Acceptance).  If the Borrowers  accomplish the replacement or repayment
     of such Lender within 120 days  following the demand,  the Borrowers  shall
     only owe any such  Lenders  amounts  under  ss.5.6,  ss.5.7 or  ss.5.8,  as
     applicable,  hereof through the date of  replacement  or repayment.  If the
     Borrowers do not accomplish either  replacement or repayment of such Lender
     within such 120 days,  the  Borrowers  shall owe such Lender in  accordance
     with the terms of any  written  agreement  reached  between  Lender and the
     Borrowers,  and, if no such agreement has been reached, the Borrowers shall
     owe such  Lender in  accordance  with the terms and  provisions  of ss.5.6,
     ss.5.7 or ss.5.8,  as applicable.  If the Total Revolving Credit Commitment
     is reduced by the Borrower  pursuant to this ss.5.16(a),  the Borrowers and
     the Lenders agree that the  Commitment  Percentages  of each Lender will be
     automatically  ratably  adjusted  to reflect  such  reduction  of the Total
     Revolving Credit Commitment.

          (b) If (i) there  exists no  Default  or Event of  Default on any such
     date and no  Default  or Event of  Default  shall be caused  by the  action
     permitted  below and (ii) any Lender  refuses to consent to any  amendment,
     waiver  or  consent  to any  provision  hereof or in any Loan  Document  in
     accordance with the terms of ss.26 (other than an amendment to increase the
     Revolving Credit Commitment of such Lender), but to which each other Lender
     has  previously  agreed,  then,  the Borrowers  may, with the prior written
     consent  of the  Agent,  within  ninety  (90)  days  after the date of such
     consent,  amendment  or waiver,  replace  such Lender in whole with another
     Eligible  Assignee,  pursuant to an Assignment and Acceptance and otherwise
     in accordance with the terms of ss.19.


                                      -45-


                     6. COLLATERAL SECURITY AND GUARANTIES.

     7.4. Financial Statements and Projections.

          7.4.1.  Fiscal Year. The Borrowers and each of their Subsidiaries have

     would  result  in any  material  change  in any of  such  projections.  The
     projections are based upon reasonable estimates and assumptions,  have been
     prepared  on the basis of the  assumptions  stated  therein and reflect the

pending or to the best of each Borrowers'  knowledge,  threatened against any of
the  Borrowers  or any of their  Subsidiaries  before  any  court,  tribunal  or
administrative  agency  or  board  that,  if  adversely  determined,   could  be
reasonably  expected  to,  either  in any case or in the  aggregate,  (a) have a
Materially  Adverse  Effect  or (b)  result  in any  substantial  liability  not
adequately  covered  by  insurance,  or for  which  adequate  reserves  are  not

Subsidiaries.

     7.14.  Perfection  of  Security  Interest.  Each of the  Borrowers  and the
Guarantors  have  delivered to, or deposited  with,  the Agent all documents and
instruments  necessary  for the  filings,  assignments,  pledges  and all  other
actions to be taken that are necessary or advisable,  under  Applicable  Law, to
establish  and perfect  the Agent's  security  interest in the  Collateral.  The
Collateral and the Agent's rights with respect to the Collateral are not subject
to any setoff,  claims,  withholdings  or other  defenses  except for  Permitted
Liens.  The Borrowers or  Subsidiaries  of the  Borrowers  party to the Security
Agreement  are the  owners of their  respective  Collateral  free from any Lien,

     7.15. Certain  Transactions.  Except for arm's length transactions pursuant
to which  the  Borrowers  or any of their  Subsidiaries  makes  payments  in the
ordinary  course of business upon terms no less favorable than such Borrowers or

directors,  or  employees  of the  Borrowers  or any of  their  Subsidiaries  is
presently  a  party  to any  transaction  with  the  Borrowers  or any of  their
Subsidiaries  (other than for services as  employees,  officers and  directors),

furnishing  of  services  to or by,  providing  for  rental of real or  personal
property to or from,  or  otherwise  requiring  payments to or from any officer,

or any such  employee  has a  substantial  interest or is an officer,  director,
trustee or partner.

     7.16. Employee Benefit Plans.

          7.16.1.  In  General.  Except as  disclosed  on  Schedule  7.16,  each
     Employee Benefit Plan and each Guaranteed  Pension Plan has been maintained
     and operated in compliance in all material  respects with the provisions of
     ERISA and, to the extent applicable, the Code, including but not limited to
     the  provisions  thereunder  respecting  prohibited  transactions  and  the
     bonding of fiduciaries and other persons handling plan funds as required by
     ss.412 of ERISA.  The Borrowers have heretofore  delivered to the Agent the
     most  recently  completed  annual  report,  Form  5500,  with all  required
     attachments,  and  actuarial  statement  required  to  be  submitted  under
     ss.103(d) of ERISA, with respect to each Guaranteed Pension Plan.


                                      -50-


          7.16.2.  Terminability  of  Welfare  Plans.  Except  as  disclosed  on
     Schedule  7.16,  no Employee  Benefit  Plan,  which is an employee  welfare
     benefit plan within the meaning of ss.3(1) or ss.3(2)(B) of ERISA, provides
     retiree  group  health  benefits,  except as required by Title I, Part 6 of
     ERISA or applicable state insurance laws.

          7.16.3.  Guaranteed  Pension  Plans.  Except as  disclosed on Schedule
     7.16, each contribution  required to be made to a Guaranteed  Pension Plan,
     whether  required  to be made to avoid  the  incurrence  of an  accumulated
     funding deficiency, the notice or lien provisions of ss.302(f) of ERISA, or
     otherwise,  has been  timely  made.  No  waiver of an  accumulated  funding
     deficiency  or extension of  amortization  periods has been  received  with
     respect to any  Guaranteed  Pension Plan, and none of the Borrowers nor any
     ERISA  Affiliate are obligated to or has posted security in connection with
     an amendment to a  Guaranteed  Pension Plan  pursuant to ss.307 of ERISA or
     ss.401(a)(29)  of the Code.  No liability to the PBGC (other than  required
     insurance  premiums,  all of which have been paid) has been incurred by the
     Borrowers or any ERISA  Affiliate  with respect to any  Guaranteed  Pension
     Plan and there has not been any ERISA Reportable Event (other than an ERISA
     Reportable  Event as to which the  requirement  of 30 days  notice has been
     waived),  or any other event or condition which presents a material risk of
     termination of any  Guaranteed  Pension Plan by the PBGC. As of the Closing
     Date, based on the latest valuation of each Guaranteed  Pension Plan (which
     in  each  case   occurred   within  twelve  months  of  the  date  of  this
     representation),  and on the actuarial methods and assumptions employed for
     that valuation,  the aggregate  benefit  liabilities of all such Guaranteed
     Pension  Plans  within  the  meaning of ss.4001 of ERISA did not exceed the
     aggregate value of the assets of all such Guaranteed  Pension Plans by more
     than $20,000,000, disregarding for this purpose the benefit liabilities and
     assets of any  Guaranteed  Pension  Plan with  assets in excess of  benefit

     Governmental Authority of competent jurisdiction shall make a determination
     that, or issue a judgment,  order, decree or ruling to the effect that, any
     one or more of the Loan Documents is illegal,  invalid or  unenforceable in
     accordance with the terms thereof;

          (k) any of the Borrowers or any ERISA  Affiliate  incurs any liability
     to the PBGC or a Guaranteed  Pension Plan  pursuant to Title IV of ERISA in
     an aggregate  amount exceeding  $1,000,000,  or any of the Borrowers or any
     ERISA Affiliate is assessed  withdrawal  liability  pursuant to Title IV of
     ERISA by a Multiemployer Plan requiring aggregate annual payments exceeding
     $1,000,000,  or any of the  following  occurs with  respect to a Guaranteed
     Pension  Plan:  (i) an  ERISA  Reportable  Event,  or a  failure  to make a
     required  installment or other payment  (within the meaning of ss.302(f)(1)
     of ERISA),  provided that the Agent determines in its reasonable discretion
     that such event (A) could be expected to result in  liability of any of the
     Borrowers  or any of  their  Subsidiaries  to the  PBGC or such  Guaranteed
     Pension  Plan in an aggregate  amount  exceeding  $1,000,000  and (B) could
     constitute  grounds for the termination of such Guaranteed  Pension Plan by
     the PBGC, for the  appointment by the  appropriate  United States  District
     Court of a trustee to administer  such  Guaranteed  Pension Plan or for the
     imposition of a Lien in favor of such Guaranteed  Pension Plan; or (ii) the
     appointment  by a United States  District  Court of a trustee to administer
     such  Guaranteed  Pension  Plan;  or (iii) the  institution  by the PBGC of
     proceedings to terminate such Guaranteed Pension Plan;

          (l)  any  of the  Borrowers  or any of  their  Subsidiaries  shall  be
     enjoined,  restrained  or in any way prevented by the order of any court or
     any  administrative  or regulatory agency from conducting any material part
     of its  business  and such  order  shall  continue  in effect for more than
     thirty (30) days;


                                      -76-


          (m)  there  shall  occur any  material  damage  to, or loss,  theft or
     destruction  of, any  Collateral,  whether or not  insured,  or any strike,
     lockout, labor dispute, embargo,  condemnation, act of God or public enemy,
     or other  casualty,  which in any such case  causes,  for more than fifteen
     (15) consecutive days, the cessation or substantial  curtailment of revenue
     producing  activities  at any  facility of any of the  Borrowers  or any of
     their Subsidiaries if such event or circumstance is not covered by business
     interruption insurance and would have a Materially Adverse Effect;

          (n) there  shall  occur  the loss,  suspension  or  revocation  of, or
     failure to renew,  any license or permit now held or hereafter  acquired by
     any of the Borrowers or any of their Subsidiaries if such loss, suspension,
     revocation or failure to renew would have a Materially Adverse Effect;

          (o) a First  Mortgage  Note Change of Control  shall have occurred and
     the Borrowers shall not have  demonstrated to the satisfaction of the Agent
     that the Borrowers have commitments  sufficient to redeem in full the First
     Mortgage Notes;

          (p) any person (other than  Glencore) or group of persons  (within the
     meaning  of the  Exchange  Act) shall have  acquired  beneficial  ownership
     (within  the  meaning  of Rule  13d-3  promulgated  by the  Securities  and
     Exchange  Commission under said Act) of fifty-one  percent (51%) or more of
     the outstanding shares of common stock of Century Aluminum; or

          (q) Century  Aluminum  shall  (subject to ss.8.6  hereof) at any time,
     directly  or  indirectly  through  one or  more  Subsidiaries,  legally  or
     beneficially  own less than one hundred percent (100%) of the shares of the
     capital  stock  and  other  outstanding  equity  interests  of  each of the
     Borrowers (other than itself) and the other Guarantors.

then, and in any such event,  so long as the same may be  continuing,  the Agent
may, and upon the request of the Majority Lenders shall, by notice in writing to
the Borrower  declare all amounts  owing with respect to this Credit  Agreement,
the Notes and the other Loan Documents and all Reimbursement  Obligations to be,
and they shall thereupon  forthwith become,  immediately due and payable without
presentment,  demand,  protest  or other  notice of any  kind,  all of which are
hereby  expressly  waived by the  Borrowers;  provided  that in the event of any
Event of  Default  specified  in  ss.ss.13.1(g),  13.1(h) or  13.1(j),  all such
amounts shall become  immediately due and payable  automatically and without any
requirement of notice from the Agent or any Lender.

     13.2.  Termination  of  Commitments.  If any one or more of the  Events  of
Default  specified in ss.13.1(g)  or ss.13.1(h)  shall occur with respect to any
Borrower,  any unused portion of the credit hereunder shall forthwith  terminate
and each of the Lenders  shall be relieved  of all further  obligations  to make
Loans to the  Borrowers  and the  Issuing  bank shall be relieved of all further
obligations to issue,  extend or renew Letters of Credit.  If any other Event of
Default  shall have  occurred and be  continuing,  or if on any Drawdown Date or
other  date for  issuing,  extending  or  renewing  any  Letter  of  Credit  the
conditions precedent to the making of the Loans to be made on such Drawdown Date
or (as the case may be) to issuing,  extending or renewing such Letter of Credit
on such other date are not satisfied, the Agent may and, upon the request of the
Majority  Lenders,  shall,  by notice to the  Borrowers,  terminate  the  unused
portion of the credit  hereunder,  and upon such notice  being given such unused
portion of the credit  hereunder  shall  terminate  immediately  and each of the
Lenders shall be relieved of all further obligations to make Loans and the Agent
shall be relieved of all further  obligations to issue,  extend or renew Letters
of Credit. No termination of the credit hereunder shall relieve the Borrowers or
any of the Guarantors of any of the Obligations.


                                      -77-


     13.3. Remedies. In case any one or more of the Events of Default shall have
occurred  and  be  continuing,  and  whether  or  not  the  Lenders  shall  have
accelerated the maturity of the Loans pursuant to ss.13.1,  each Lender, if owed
any amount with respect to the Loans or the Reimbursement Obligations, may, with
the consent of the Majority  Lenders but not  otherwise,  proceed to protect and
enforce  its  rights  by suit in  equity,  action  at law or  other  appropriate
proceeding,  whether for the specific  performance  of any covenant or agreement
contained  in  this  Credit  Agreement  and  the  other  Loan  Documents  or any
instrument  pursuant  to which the  Obligations  to such  Lender are  evidenced,
including  as  permitted  by  applicable  law  the  obtaining  of the  ex  parte
appointment  of a  receiver,  and,  if such  amount  shall have  become  due, by
declaration  or otherwise,  proceed to enforce the payment  thereof or any other
legal or equitable  right of such Lender.  No remedy herein  conferred  upon any
Lender or the  Agent or the  holder of any Note or  purchaser  of any  Letter of
Credit  Participation  is intended to be  exclusive of any other remedy and each
and every  remedy  shall be  cumulative  and shall be in addition to every other
remedy given  hereunder  or now or hereafter  existing at law or in equity or by
statute or any other provision of law.

     13.4. Distribution of Collateral Proceeds. In the event that, following the
occurrence  or during the  continuance  of any Default or Event of Default,  the
Agent or any Lender,  as the case may be, receives any monies in connection with
the enforcement of any the Security Documents,  as the case may be, or otherwise
with respect to the realization upon any of the Collateral, such monies shall be
distributed for application as follows:

          (a)  First,   to  the  payment  of,  or  (as  the  case  may  be)  the
     reimbursement  of the  Agent for or in  respect  of all  reasonable  costs,
     expenses,  disbursements  and  losses  which  shall have been  incurred  or
     sustained by the Agent in connection  with the collection of such monies by
     the Agent, for the exercise,  protection or enforcement by the Agent of all
     or any of the rights,  remedies,  powers and  privileges of the Agent under
     this Credit  Agreement or any of the other Loan  Documents or in respect of
     the Collateral or in support of any provision of adequate  indemnity to the
     Agent  against  any taxes or Liens  which by law shall  have,  or may have,
     priority over the rights of the Agent to such monies;

          (b)  Second,   to  all  other   Obligations   (other  than  Derivative
     Obligations)  in such  order or  preference  as the  Majority  Lenders  may
     determine; provided, however, that (i) distributions shall be made (A) pari
     passu among Obligations with respect to the Agent's Fee payable pursuant to
     ss.5.2 and all other  Obligations  (other than Derivative  Obligations) and
     (B) with respect to each type of Obligation  owing to the Lenders,  such as
     interest,  principal,  Fees and expenses,  among the Lenders pro rata,  and
     (ii) the Agent may in its  discretion  make proper  allowance  to take into
     account any Obligations not then due and payable;

          (c) Third,  to the  Obligations  which are Derivative  Obligations pro
     rata among such Banks who are participants in such Derivative Obligations;

          (d) Fourth,  upon payment and satisfaction in full or other provisions
     for payment in full satisfactory to the Lenders and the Agent of all of the
     Obligations to the payment of any obligations  required to be paid pursuant
     to ss.9-504(1)(c) of the UCC of the State of New York; and

          (e) Fifth,  the excess,  if any, shall be returned to the Borrowers or
     to such other Persons as are entitled thereto.


                                      -78-


                                   14. SETOFF.

     Regardless of the adequacy of any collateral, during the continuance of any
Event of Default,  any deposits or other sums credited by or due from any of the
Lenders to the Borrowers and any  securities or other  property of the Borrowers
in the  possession  of such  Lender may be applied to or set off by such  Lender
against the payment of Obligations and any and all other liabilities, direct, or
indirect,  absolute  or  contingent,  due or to  become  due,  now  existing  or
hereafter arising,  of the Borrowers to such Lender.  Each of the Lenders agrees
with each other  Lender  that (i) if an amount to be set off is to be applied to
Indebtedness of the Borrowers to such Lender, other than Indebtedness  evidenced
by the Notes held by such Lender or constituting  Reimbursement Obligations owed
to such Lender,  such amount shall be applied ratably to such other Indebtedness
and to the  Indebtedness  evidenced  by all such  Notes  held by such  Lender or
constituting  Reimbursement  Obligations  owed to such Lender,  and (ii) if such
Lender shall receive from any of the  Borrowers,  whether by voluntary  payment,
exercise of the right of setoff, counterclaim,  cross action, enforcement of the
claim evidenced by the Notes held by, or constituting  Reimbursement Obligations
owed to, such Lender by  proceedings  against any of the  Borrowers at law or in
equity  or  by  proof  thereof  in  bankruptcy,   reorganization,   liquidation,
receivership or similar proceedings, or otherwise, and shall retain and apply to
the payment of the Note or Notes held by, or Reimbursement  Obligations owed to,
such Lender any amount in excess of its ratable portion of the payments received
by all of the  Lenders  with  respect to the Notes  held by,  and  Reimbursement
Obligations owed to, all of the Lenders,  such Lender will make such disposition
and arrangements  with the other Lenders with respect to such excess,  either by
way of distribution, pro tanto assignment of claims, subrogation or otherwise as
shall  result in each  Lender  receiving  in  respect of the Notes held by it or
Reimbursement  obligations owed it, its proportionate payment as contemplated by
this Credit  Agreement;  provided that if all or any part of such excess payment
is thereafter  recovered from such Lender,  such  disposition  and  arrangements
shall be rescinded and the amount  restored to the extent of such recovery,  but
without interest.


                                      -79-


                                 15. THE AGENT.

     15.1. Authorization.

          (a) The Agent is  authorized  to take such action on behalf of each of
     the Lenders and to exercise all such powers as are  hereunder and under any
     of the other Loan  Documents  and any related  documents  delegated  to the
     Agent,  together  with such  powers  as are  reasonably  incident  thereto,
     provided that no duties or responsibilities not expressly assumed herein or
     therein shall be implied to have been assumed by the Agent.

          (b) The relationship between the Agent and each of the Lenders is that
     of  an  independent  contractor.  The  use  of  the  term  "Agent"  is  for
     convenience  only and is used to  describe,  as a form of  convention,  the
     independent  contractual  relationship  between  the  Agent and each of the
     Lenders.  Nothing  contained  in this Credit  Agreement  nor the other Loan
     Documents shall be construed to create an agency,  trust or other fiduciary
     relationship between the Agent and any of the Lenders.

          (c) As an independent  contractor empowered by the Lenders to exercise
     certain rights and perform  certain duties and  responsibilities  hereunder
     and  under  the  other  Loan   Documents,   the  Agent  is  nevertheless  a
     "representative"  of the  Lenders,  as that term is defined in Article 1 of
     the UCC,  for  purposes  of actions  for the benefit of the Lenders and the
     Agent with respect to all collateral  security and guaranties  contemplated
     by the Loan Documents. Such actions include the designation of the Agent as
     "secured party" or the like on all financing statements and other documents
     and instruments, whether recorded or otherwise, relating to the attachment,
     perfection, priority or enforcement of any security interests in collateral
     security  intended  to secure  the  payment  or  performance  of any of the
     Obligations, all for the benefit of the Lenders and the Agent.

     15.2.  Employees and Agents.  The Agent may exercise its powers and execute
its duties by or through  employees or agents and shall be entitled to take, and
to rely on, advice of counsel  concerning  all matters  pertaining to its rights
and duties under this Credit  Agreement and the other Loan Documents.  The Agent
may utilize the services of such Persons as the Agent in its sole discretion may
reasonably  determine,  and all reasonable fees and expenses of any such Persons
shall be paid by the Borrowers.

     15.3.  No  Liability.  Neither  the  Agent  nor  any of  its  shareholders,
directors,  officers or employees nor any other Person  assisting  them in their
duties  nor any  agent or  employee  thereof,  shall be liable  for any  waiver,
consent or approval given or any action taken,  or omitted to be taken,  in good
faith by it or them  hereunder or under any of the other Loan  Documents,  or in
connection herewith or therewith,  or be responsible for the consequences of any
oversight or error of judgment  whatsoever,  except that the Agent or such other
Person,  as the  case  may be,  may be  liable  for  losses  due to its  willful
misconduct or gross negligence.


                                      -80-


     15.4. No Representations.

          15.4.1.  General. The Agent shall not be responsible for the execution
     or validity or  enforceability  of this Credit  Agreement,  the Notes,  the
     Letters of Credit, any of the other Loan Documents or any instrument at any
     time constituting,  or intended to constitute,  collateral security for the
     Notes,  or for  the  value  of any  such  collateral  security  or for  the
     validity,  enforceability  or collectability of any such amounts owing with
     respect to the Notes,  or for any  recitals or  statements,  warranties  or
     representations made herein or in any of the other Loan Documents or in any
     certificate or instrument  hereafter furnished to it by or on behalf of any
     of the Borrowers or any of their Subsidiaries,  or be bound to ascertain or
     inquire  as  to  the  performance  or  observance  of  any  of  the  terms,
     conditions, covenants or agreements herein or in any instrument at any time
     constituting, or intended to constitute,  collateral security for the Notes
     or to  inspect  any of  the  properties,  books  or  records  of any of the
     Borrowers  or any of their  Subsidiaries.  The Agent  shall not be bound to
     ascertain whether any notice, consent, waiver or request delivered to it by
     any of the Borrowers or any holder of any of the Notes shall have been duly
     authorized or is true,  accurate and  complete.  The Agent has not made nor
     does it now make any representations or warranties, express or implied, nor
     does it assume any  liability  to the  Lenders,  with respect to the credit
     worthiness or financial  conditions of any of the Borrowers or any of their
     Subsidiaries.  Each  Lender  acknowledges  that it has,  independently  and
     without  reliance upon the Agent or any other  Lender,  and based upon such
     information and documents as it has deemed appropriate, made its own credit
     analysis and decision to enter into this Credit Agreement.

          15.4.2.  Closing  Documentation,  etc.  For  purposes  of  determining
     compliance  with the conditions set forth in ss.10,  11 and 12, each Lender
     that has executed this Credit  Agreement  shall be deemed to have consented
     to, approved or accepted, or to be satisfied with, each document and matter
     either sent, or made available, by the Agent or the Arranger to such Lender
     for consent, approval,  acceptance or satisfaction,  or required thereunder
     to be to be consent to or approved by or acceptable or satisfactory to such
     Lender,  unless an officer  of the Agent or the  Arranger  active  upon the
     Borrowers'  account  shall have  received  notice from such Lender not less
     than five  (5)days  prior to the Closing  Date,  specifying  such  Lender's
     objection  thereto  and such  objection  shall not have been  withdrawn  by
     notice  to the  Agent or the  Arranger  to such  effect  on or prior to the
     Closing Date.

     15.5. Payments.

          15.5.1.  Payments to Agent.  A payment by any of the  Borrowers to the
     Agent  hereunder or any of the other Loan  Documents for the account of any
     Lender shall constitute a payment to such Lender. The Agent agrees promptly
     to  distribute  to each  Lender  such  Lender's  pro rata share of payments
     received by the Agent for the account of the  Lenders  except as  otherwise
     expressly provided herein or in any of the other Loan Documents.


                                      -81-


          15.5.2.  Distribution  by Agent.  If in the  opinion  of the Agent the
     distribution of any amount received by it in such capacity hereunder, under
     the Notes or under any of the other  Loan  Documents  might  involve  it in
     liability,  it may refrain from making distribution until its right to make
     distribution   shall  have  been   adjudicated  by  a  court  of  competent
     jurisdiction.  If a court of competent  jurisdiction shall adjudge that any
     amount received and  distributed by the Agent is to be repaid,  each Person
     to whom any such  distribution  shall have been made shall  either repay to
     the Agent its proportionate share of the amount so adjudged to be repaid or
     shall  pay over the same in such  manner  and to such  Persons  as shall be
     determined by such court.

          15.5.3.  Delinquent Lenders.  Notwithstanding anything to the contrary
     contained in this Credit Agreement or any of the other Loan Documents,  any
     Lender that fails (i) to make  available to the Agent its pro rata share of
     any Loan or to  purchase  any  Letter  of Credit  Participation  or (ii) to
     comply with the provisions of ss.14 with respect to making dispositions and
     arrangements  with the other  Lenders,  where  such  Lender's  share of any
     payment received,  whether by setoff or otherwise,  is in excess of its pro
     rata share of such payments due and payable to all of the Lenders,  in each
     case as, when and to the full extent  required  by the  provisions  of this
     Credit Agreement,  shall be deemed  delinquent (a "Delinquent  Lender") and
     shall be deemed a Delinquent  Lender until such time as such delinquency is
     satisfied. A Delinquent Lender shall be deemed to have assigned any and all
     payments due to it from the  Borrowers,  whether on account of  outstanding
     Loans, Unpaid Reimbursement  Obligations,  interest,  fees or otherwise, to
     the remaining  nondelinquent  Lenders for application to, and reduction of,
     their  respective  pro rata  shares of all  outstanding  Loans  and  Unpaid
     Reimbursement  Obligations.  The  Delinquent  Lender hereby  authorizes the
     Agent  to  distribute  such  payments  to  the  nondelinquent   Lenders  in
     proportion to their respective pro rata shares of all outstanding Loans and
     Unpaid  Reimbursement  Obligations.  A Delinquent Lender shall be deemed to
     have  satisfied  in  full  a  delinquency  when  and  if,  as a  result  of
     application of the assigned  payments to all  outstanding  Loans and Unpaid
     Reimbursement  Obligations  of  the  nondelinquent  Lenders,  the  Lenders'
     respective   pro  rata   shares  of  all   outstanding   Loans  and  Unpaid
     Reimbursement  Obligations  have  returned  to those in effect  immediately
     prior to such  delinquency  and  without  giving  effect to the  nonpayment
     causing such delinquency.

     15.6.  Holders of Notes. The Agent may deem and treat the payee of any Note
or the purchaser of any Letter of Credit  Participation as the absolute owner or
purchaser  thereof for all purposes hereof until it shall have been furnished in
writing with a different name by such payee or by a subsequent holder,  assignee
or transferee.


                                      -82-


     15.7.  Indemnity.  The Lenders  ratably  agree hereby to indemnify and hold
harmless  the Agent and its  affiliates  from and  against  any and all  claims,
actions and suits (whether  groundless or otherwise),  losses,  damages,  costs,
expenses  (including  any expenses for which the Agent or such affiliate has not
been reimbursed by the Borrowers as required by ss.16), and liabilities of every
nature and  character  arising out of or related to this Credit  Agreement,  the
Notes,  or any of the other Loan Documents or the  transactions  contemplated or
evidenced  hereby  or  thereby,  or  the  Agent's  actions  taken  hereunder  or
thereunder,  except to the extent that any of the same shall be directly  caused
by the Agent's willful misconduct or gross negligence.

     15.8.  Agent as Lender.  In its individual  capacity,  Fleet shall have the
same  obligations  and the same rights,  powers and privileges in respect to its
Revolving Credit  Commitments and the Loans made by it, and as the holder of any
of the Notes and as the purchaser of any Letter of Credit Participations,  as it
would have were it not also the Agent.

     15.9.  Resignation.  The Agent may resign at any time by giving  sixty (60)
days prior written  notice  thereof to the Lenders and the  Borrowers.  Upon any
such  resignation,  the  Majority  Lenders  shall  have the  right to  appoint a
successor Agent. Unless a Default or Event of Default shall have occurred and be
continuing,  such successor Agent shall be reasonably  acceptable to each of the
Borrowers.  If no  successor  Agent shall have been so appointed by the Majority
Lenders and shall have accepted such  appointment  within thirty (30) days after
the retiring  Agent's giving of notice of  resignation,  then the retiring Agent
may,  on behalf of the  Lenders,  appoint a  successor  Agent,  which shall be a
financial  institution having a rating of not less than "A" or its equivalent by
Standard & Poor's  Corporation.  Upon the acceptance of any appointment as Agent
hereunder by a successor Agent,  such successor Agent shall thereupon succeed to
and become  vested with all the  rights,  powers,  privileges  and duties of the
retiring  Agent,  and the retiring Agent shall be discharged from its duties and
obligations hereunder. After any retiring Agent's resignation, the provisions of
this Credit  Agreement and the other Loan Documents shall continue in effect for
its benefit in respect of any  actions  taken or omitted to be taken by it while
it was acting as Agent.

     15.10.  Notification  of  Defaults  and  Events  of  Default;  Delivery  of
Information; Etc..

          (a) Each Lender hereby agrees that,  upon learning of the existence of
     a  Default  or an Event of  Default,  it shall  promptly  notify  the Agent
     thereof. The Agent hereby agrees that upon receipt of any notice under this
     ss.15.10 it shall  promptly  notify the other  Lenders of the  existence of
     such Default or Event of Default.

          (b) The Agent hereby  agrees that upon receipt of any of the financial
     statements, certificates or information delivered to the Agent under ss.8.4
     it shall promptly deliver copies thereof to the other Lenders.

          (c) The Agent  hereby  agrees  that upon  receipt of any notice  under
     ss.8.5 it shall  promptly  notify the other  Lenders of the content of such
     notice.


                                      -83-


     15.11.  Duties in the Case of  Enforcement.  In case one of more  Events of
Default have occurred and shall be continuing,  and whether or not  acceleration
of the Obligations shall have occurred,  the Agent shall, if (i) so requested by
the  Majority  Lenders  and (ii) the  Lenders  have  provided  to the Agent such
additional  indemnities and assurances  against  expenses and liabilities as the
Agent may reasonably request,  proceed to enforce the provisions of the Security
Documents,  as the case may be, authorizing the sale or other disposition of all
or any part of the  Collateral  and  exercise  all or any such  other  legal and
equitable  and  other  rights  or  remedies  as it may have in  respect  of such
Collateral.  The  Majority  Lenders  may  direct  the Agent in writing as to the
method and the extent of any such sale or other disposition,  the Lenders hereby
agreeing to indemnify and hold the Agent, harmless from all liabilities incurred
in respect of all actions taken or omitted in accordance  with such  directions,
provided  that the Agent need not comply with any such  direction  to the extent
that the Agent reasonably believes the Agent's compliance with such direction to
be unlawful or commercially unreasonable in any applicable jurisdiction.

     15.12.  Replacement  of Agent.  Notwithstanding  anything  to the  contrary
contained  in  this  Credit  Agreement,  at any  time  that  Fleet's  Commitment
Percentage  shall be less than fifteen percent (15%), the Borrowers may, so long
as no Default or Event of Default is then  continuing,  replace  Fleet as Agent;
provided,  however,  that any successor Agent proposed by the Borrowers shall be
subject to the  approval of the Majority  Lenders.  Upon the  acceptance  of any
appointment  as Agent  hereunder by the  Borrower,  such  successor  Agent shall
thereupon succeed to and become vested with all the rights,  powers,  privileges
and duties of the Agent,  and Fleet in its capacity as Agent shall be discharged
from its duties  and  obligations  hereunder.  After any such  replacement,  the
provisions of this Credit  Agreement and the other Loan Documents shall continue
in effect for its benefit in respect of any actions taken or omitted to be taken
by Fleet while it was acting as Agent.

                        16. EXPENSES AND INDEMNIFICATION.

of the  Borrowers  or any of the  Guarantors  and  (vii)  all  reasonable  fees,
expenses and  disbursements  of any Lender or the Agent  incurred in  connection

the  Arranger,  the  Issuing  Bank,  the Agent,  the  Lenders  and each of their

Affiliates shall be entitled to select their own counsel and, in addition to the
foregoing indemnity, the Borrowers agree to pay promptly the reasonable fees and

               17. TREATMENT OF CERTAIN CONFIDENTIAL INFORMATION.

acknowledge that from time to time financial  advisory,  investment  banking and
other  services  may be offered or provided to the  Borrowers  or one or more of
their Subsidiaries,  in connection with this Credit Agreement or otherwise, by a
Section 20 Subsidiary.  Each Borrower,  for itself and each of its Subsidiaries,
hereby  authorizes  (a) such Section 20  Subsidiary  to share with the Agent and

Lender by such  Borrower  or any of its  Subsidiaries  pursuant  to this  Credit
Agreement,  or in connection with the decision of such Lender to enter into this
Credit Agreement;  it being  understood,  in each case, that any such Section 20
Subsidiary  receiving  such  information  shall be bound by the  confidentiality
provisions  of this  Credit  Agreement.  Such  authorization  shall  survive the
payment and satisfaction in full of all of Obligations.

     17.2. Confidentiality.  Each of the Lenders and the Agent agrees, on behalf
of  itself  and  each of its  affiliates,  directors,  officers,  employees  and
representatives,   to  use  reasonable  precautions  to  keep  confidential,  in

of the same nature and in accordance with safe and sound banking practices,  any
non-public  information  supplied  to  it by  the  Borrowers  or  any  of  their
Subsidiaries pursuant to this Credit Agreement that is identified by such Person
as being  confidential  at the time the same is  delivered to the Lenders or the

information  (a) after such  information  shall have  become  public  other than
through a violation of this ss.17, (b) to the extent required by statute,  rule,
regulation  or  judicial  process,  (c) to counsel for any of the Lenders or the
Agent,  (d)  to  bank  examiners  or  any  other  regulatory   authority  having

the Agent,  any of the Lenders or any Section 20  Subsidiary,  (f) in connection
with any  litigation  to which any one or more of the Lenders,  the Agent or any
Section 20  Subsidiary  is a party,  or in connection  with the  enforcement  of
rights  or  remedies  hereunder  or under  any  other  Loan  Document,  (g) to a
Subsidiary  or  affiliate  of such  Lender as  provided in ss.17.1 or (h) to any
assignee or participant (or prospective assignee or participant) so long as such
assignee  or  participant  agrees  to be bound  by the  provisions  of  ss.19.6.
Moreover,  the  Agent,  the  Lenders  and any  Section 20  Subsidiary  is hereby
expressly  permitted by the Borrowers to refer to any of the Borrowers and their
Subsidiaries  in  connection  with  any  advertising,   promotion  or  marketing
undertaken  by such Agent,  such Lender or such Section 20  Subsidiary  and, for
such purpose,  such Agent, such Lender or such Section 20 Subsidiary may utilize
any trade name, trademark,  logo or other distinctive symbol associated with any
of the Borrowers or any of their Subsidiaries or any of their businesses.


                                      -86-


     17.3. Prior Notification.  Unless specifically prohibited by Applicable Law
or court  order,  each of the Lenders and the Agent shall,  prior to  disclosure
thereof,  notify  the  Borrowers  of any  request  for  disclosure  of any  such
non-public  information by any  governmental  agency or  representative  thereof
(other than any such request in connection  with an examination of the financial
condition  of such  Lender by such  governmental  agency) or  pursuant  to legal
process.

     17.4. Other. In no event shall any of the Lenders or the Agent be obligated
or required to return any materials furnished to it or any Section 20 Subsidiary
by the Borrowers or any of their  Subsidiaries.  The  obligations of each Lender
under this ss.17 shall  supersede  and replace  the  obligations  of such Lender
under any  confidentiality  letter  in  respect  of this  financing  signed  and
delivered by such Lender to the Borrowers  prior to the date hereof and shall be
binding upon any assignee of, or purchaser of any participation in, any interest
in any of the Loans or Reimbursement Obligations from any Lender.

                         18. SURVIVAL OF COVENANTS, ETC.

     All covenants,  agreements,  representations and warranties made herein, in
the  Notes,  in any of the other Loan  Documents  or in any  documents  or other
papers  delivered  by or on  behalf  of  any of the  Borrowers  or any of  their
Subsidiaries  pursuant  hereto  shall be deemed to have been  relied upon by the
Lenders,  the  Issuing  Bank and the Agent,  notwithstanding  any  investigation
heretofore or hereafter made by any of them, and shall survive the making by the
Lenders  of any of the Loans  and the  issuance,  extension  or  renewal  of any
Letters of Credit, as herein contemplated,  and shall continue in full force and
effect  so long as any  Letter of Credit or any  amount  due under  this  Credit
Agreement or the Notes or any of the other Loan Documents remains outstanding or
any  Lender has any  obligation  to make any Loans or the  Issuing  Bank has any
obligation to issue,  extend or renew any Letter of Credit, and for such further
time as may be  otherwise  expressly  specified  in this Credit  Agreement.  All
statements  contained in any certificate or other paper delivered to any Lender,
the  Issuing  Bank  or the  Agent  at any  time  by or on  behalf  of any of the
Borrowers or any of the  Guarantors  pursuant  hereto or in connection  with the
transactions contemplated hereby shall constitute representations and warranties
by such Borrowers or such Guarantor hereunder.


                                      -87-


                        19. ASSIGNMENT AND PARTICIPATION.

     19.1. Conditions to Assignment by Lenders.  Except as provided herein, each
Lender  may  assign to one or more  Eligible  Assignees  all or a portion of its
interests,  rights and obligations under this Credit Agreement (including all or
a portion of its Commitment  Percentages and Commitments and the same portion of
the Loans at the time owing to it,  the Notes  held by it and its  participating
interest in the risk relating to any Letters of Credit);  provided that (i) each
of the Agent and,  unless a Default or Event of Default  shall have occurred and
be continuing,  the Borrower shall have given its prior written  consent to such
assignment,   which  consent,  in  the  case  of  the  Borrowers,  will  not  be
unreasonably  withheld  (any  increase  in  costs  to  the  Borrowers  shall  be
considered  reasonable  grounds for the Borrowers'  withholding  consent to such
assignment),  (ii)  each  such  assignment  shall  be of a  constant,  and not a
varying,  percentage of all the assigning  Lender's rights and obligations under
this  Credit  Agreement,  (iii)  each  assignment  shall  be in  the  amount  of
$5,000,000 or an integral multiple of $1,000,000  thereof,  unless it is for all
of the assigning  Lender's  interests,  rights and obligations under this Credit
Agreement,  and (iv) the parties to such assignment shall execute and deliver to
the Agent, for recording in the Register (as hereinafter defined), an Assignment
and  Acceptance,  substantially  in the form of Exhibit E hereto (an "Assignment
and Acceptance"),  together with any Notes subject to such assignment. Upon such

Assignment  and  Acceptance,  have  the  rights  and  obligations  of  a  Lender
hereunder,  and (ii) the assigning  Lender shall, to the extent provided in such
assignment and upon payment to the Agent of the  registration fee referred to in

     and beneficial  owner of the interest being assigned thereby free and clear
     of any adverse  claim,  the  assigning  Lender makes no  representation  or
     warranty, express or implied, and assumes no responsibility with respect to
     any statements, warranties or representations made in or in connection with
     this Credit Agreement or the execution, legality, validity, enforceability,
     genuineness,  sufficiency or value of this Credit Agreement, the other Loan
     Documents or any other instrument or document  furnished pursuant hereto or
     the  attachment,  perfection  or  priority  of  any  security  interest  or
     mortgage,

          (b) the  assigning  Lender  makes no  representation  or warranty  and
     assumes no  responsibility  with respect to the financial  condition of the
     Borrowers  and  their   Subsidiaries  or  any  other  Person  primarily  or
     secondarily liable in respect of any of the Obligations, or the performance
     or observance by the Borrowers and their  Subsidiaries  or any other Person
     primarily or secondarily liable in respect of any of the Obligations of any
     of their  obligations  under this Credit Agreement or any of the other Loan
     Documents or any other instrument or document  furnished pursuant hereto or
     thereto;


                                      -88-


          (c) such assignee  confirms that it has received a copy of this Credit
     Agreement,  together  with copies of the most recent  financial  statements
     referred to in ss.7.4 and ss.8.4 and such other  documents and  information
     as it has deemed  appropriate to make its own credit  analysis and decision
     to enter into such Assignment and Acceptance;

          (d) such assignee will,  independently  and without  reliance upon the
     assigning Lender, the Agent or any other Lender and based on such documents
     and information as it shall deem appropriate at the time,  continue to make
     its own credit  decisions in taking or not taking  action under this Credit
     Agreement;

          (e) such  assignee  represents  and  warrants  that it is an  Eligible
     Assignee;

          (f) such  assignee  appoints  and  authorizes  the  Agent to take such
     action as agent on its behalf and to exercise such powers under this Credit

     incidental thereto;

     share of Letter of Credit Fees in respect of outstanding Letters of Credit.

     19.3.  Register.  The Agent shall  maintain a copy of each  Assignment  and
Acceptance  delivered to it and a register or similar list (the  "Register") for
the  recordation  of the names and  addresses of the Lenders and the  Commitment
Percentage  of, and principal  amount of the Loans owing to and Letter of Credit
Participations  purchased by, the Lenders from time to time.  The entries in the
Register  shall  be  conclusive,  in the  absence  of  manifest  error,  and the
Borrowers,  the Agent  and the  Lenders  may treat  each  Person  whose  name is
recorded in the Register as a Lender  hereunder  for all purposes of this Credit
Agreement.  The Register  shall be available for inspection by the Borrowers and
the Lenders at any reasonable time and from time to time upon  reasonable  prior
notice.  Upon each such  recordation,  the assigning Lender agrees to pay to the
Agent a registration fee in the sum of $3,500.


                                      -89-


     19.4. New Notes. Upon its receipt of an Assignment and Acceptance  executed
by the  parties  to such  assignment,  together  with each Note  subject to such
assignment,  the Agent shall (i) record the information contained therein in the
Register,  and (ii) give prompt notice  thereof to the Borrowers and the Lenders
(other than the assigning  Lender).  Within five (5) Business Days after receipt
of such notice, the Borrowers,  at its own expense, shall execute and deliver to
the Agent,  in exchange  for each  surrendered  Note, a new Note to the order of
such Eligible Assignee in an amount equal to the amount assumed by such Eligible
Assignee pursuant to such Assignment and Acceptance and, if the assigning Lender
has retained some portion of its obligations  hereunder, a new Note to the order
of the  assigning  Lender  in an  amount  equal  to the  amount  retained  by it
hereunder.  Such new Notes  shall  provide  that they are  replacements  for the
surrendered  Notes,  shall  be in an  aggregate  principal  amount  equal to the
aggregate  principal  amount  of the  surrendered  Notes,  shall  be  dated  the
effective  date of such  Assignment  and  Acceptance  and shall  otherwise be in
substantially  the form of the assigned Notes.  The  surrendered  Notes shall be
cancelled and returned to the Borrower.

     19.5.  Participations.  Each Lender may sell  participations to one or more
banks  or  other  entities  in all or a  portion  of such  Lender's  rights  and
obligations  under this Credit Agreement and the other Loan Documents;  provided
that  (i)  each  such  participation  shall be in an  amount  of not  less  than
$5,000,000,  (ii) any such sale or participation shall not affect the rights and
duties of the selling Lender hereunder to the Borrowers, (iii) each Borrower and
the Agent shall  continue to deal solely and directly with the selling Lender in
connection with the selling  Lender's  rights and obligations  under this Credit
Agreement  and the other Loan  Documents,  and (iv) no Lender shall  transfer or
grant any  participating  interest  under  which the  participant  has rights to
approve any  amendment to, or any consent or waiver with respect to, this Credit
Agreement or any other Loan Document,  and all amounts  payable by the Borrowers
hereunder shall be determined as if such Lender had not sold such participation;
except that,  if amounts  outstanding  under this Credit  Agreement  are due and
unpaid,  or shall have been  declared or shall have become due and payable  upon
the occurrence of an Event of Default,  each participant shall be deemed to have
the right of set-off in respect of its  participating  interest in amounts owing
under  this  Credit  Agreement  to  the  same  extent  as if the  amount  of its
participating  interest were owing  directly to it as a Lender under this Credit
Agreement.

     19.6. Disclosure.  The Borrowers agree that in addition to disclosures made
in  accordance  with  standard and  customary  banking  practices any Lender may
disclose  information  obtained by such Lender pursuant to this Credit Agreement
to assignees or participants and potential assignees or participants  hereunder;
provided  that  such  assignees  or  participants  or  potential   assignees  or
participants shall agree (i) to treat in confidence such information unless such
information  otherwise  becomes  public  knowledge,  (ii) not to  disclose  such
information  to a third  party,  except as required by law or legal  process and
(iii) not to make use of such information for purposes of transactions unrelated
to such contemplated  assignment or participation.  For purposes of this ss.19.6
an assignee or  participant or potential  assignee or participant  may include a
counterparty  with whom such Lender has entered into or potentially  might enter
into a derivative contract referenced to credit or other risks or events arising
under this Credit Agreement or any other Loan Document.


                                      -90-


     19.7.  Assignee  or  Participant  Affiliated  with  the  Borrowers.  If any
assignee Lender is an Affiliate of any of the Borrowers,  then any such assignee
Lender  shall  have no right to vote as a Lender  hereunder  or under any of the
other  Loan  Documents  for  purposes  of  granting  consents  or waivers or for
purposes of agreeing to  amendments  or other  modifications  to any of the Loan
Documents or for purposes of making requests to the Agent pursuant to ss.13.1 or
ss.13.2, and the determination of the Majority Lenders shall for all purposes of
this Credit  Agreement  and the other Loan  Documents be made without  regard to
such  assignee   Lender's   interest  in  any  of  the  Loans  or  Reimbursement
Obligations. If any Lender sells a participating interest in any of the Loans or
Reimbursement  Obligations to a participant,  and such participant is a Borrower
or an  Affiliate  of any of the  Borrowers,  then such  transferor  Lender shall
promptly notify the Agent of the sale of such participation. A transferor Lender
shall have no right to vote as a Lender hereunder or under any of the other Loan
Documents  for  purposes  of  granting  consents  or waivers or for  purposes of
agreeing to  amendments  or  modifications  to any of the Loan  Documents or for
purposes of making  requests to the Agent  pursuant to ss.13.1 or ss.13.2 to the
extent  that such  participation  is  beneficially  owned by a  Borrower  or any
Affiliate of any of the Borrowers, and the determination of the Majority Lenders
shall for all purposes of this Credit  Agreement and the other Loan Documents be
made without  regard to the interest of such  transferor  Lender in the Loans or
Reimbursement Obligations to the extent of such participation.

     19.8.  Miscellaneous  Assignment  Provisions.  Any  assigning  Lender shall
retain its rights to be indemnified pursuant to ss.16 with respect to any claims
or actions arising prior to the date of such  assignment.  On or before the date
it becomes a party to this  Credit  Agreement  and from time to time  thereafter
upon any change in status  rendering  any  certificate  or  document  previously
delivered  pursuant  to  ss.5.7  invalid  or  inaccurate,  each  Lender  that is
organized under the laws of a jurisdiction outside the United States shall (but,
with  respect  to any  renewal or change in  status,  if legally  able to do so)
deliver to the Borrowers and the Agent  certification  as to its exemption  from
deduction or withholding  of any United States  federal  income taxes,  and each
such Lender shall comply with all Applicable Laws with respect to such exemption
and any renewal or extension thereof. If any Reference Bank transfers all of its
interest,  rights and obligations under this Credit Agreement,  the Agent shall,
in consultation with the Borrowers and with the consent of the Borrowers and the
Majority  Lenders,  appoint another Lender to act as a Reference Bank hereunder.
Anything contained in this ss.19 to the contrary notwithstanding, any Lender may
at any time  pledge all or any  portion of its  interest  and rights  under this
Credit  Agreement  (including  all or any  portion  of its  Notes) to any of the
twelve (12) Federal  Reserve Banks  organized  under ss.4 of the Federal Reserve
Act, 12 U.S.C.  ss.341. No such pledge or the enforcement  thereof shall release
the pledgor Lender from its obligations hereunder or under any of the other Loan
Documents.


                                      -91-


     19.9.  Assignment  by  Borrowers.  None of the  Borrowers  shall  assign or
transfer  any of their  rights or  obligations  under any of the Loan  Documents
without the prior written consent of each of the Lenders.

                                20. NOTICES, ETC.

     Except as  otherwise  expressly  provided  in this  Credit  Agreement,  all

Credit Agreement or the Notes or any Letter of Credit  Applications  shall be in

                            25. WAIVER OF JURY TRIAL.

obligations  hereunder  or  thereunder  or the  performance  of such  rights and
obligations.  Except as prohibited  by law, each of the Borrowers  hereby waives
any right it may have to claim or recover in any  litigation  referred to in the
preceding sentence any special, exemplary,  punitive or consequential damages or
any damages other than, or in addition to, actual damages. Each of the Borrowers
(i)  certifies  that no  representative,  agent or attorney of any Lender or the
Agent has  represented,  expressly or  otherwise,  that such Lender or the Agent
would not, in the event of litigation, seek to enforce the foregoing waivers and
(ii) acknowledges that the Agent and the Lenders have been induced to enter into
this Credit Agreement, the other Loan Documents to which it is a party by, among
other things, the waivers and certifications contained herein.

                     26. CONSENTS, AMENDMENTS, WAIVERS, ETC.

     (a) Any consent or approval  required or permitted by this Credit Agreement
to be given by the Lenders may be given, and any term of this Credit  Agreement,
the other Loan  Documents or any other  instrument  related  hereto or mentioned
herein may be amended, and the performance or observance by the Borrowers or any
of their  Subsidiaries  of any terms of this  Credit  Agreement,  the other Loan
Documents or such other instrument or the continuance of any Default or Event of
Default may be waived (either  generally or in a particular  instance and either
retroactively or prospectively)  with, but only with, the written consent of the
Borrowers and the written consent of the Majority Lenders.  Notwithstanding  the
foregoing:

        (i)     the rate of interest on the Notes (other than interest  accruing
                pursuant to ss.5.12.2 following the effective date of any waiver
                by the  Majority  Lenders  of the  Default  or Event of  Default
                relating thereto) or the amount of any Commitment Fees or Letter
                of Credit Fees may not be decreased  without the written consent
                of each Lender affected thereby;


                                      -93-


        (ii)    No Lender's Revolving Credit Commitment may be increased without
                the written consent of such Lender and the Borrower;

        (iii)   the  Maturity  Date may not be  postponed  without  the  written
                consent of each Lender affected thereby;

        (iv)    the advance rates set forth in the  definition of Borrowing Base
                may not be increased  without the written  consent of all of the
                Lenders,

        (v)     this ss.26 and the  definitions  of Majority  Lenders may not be
                amended, without the written consent of all of the Lenders;

        (vi)    the  definition  of Minimum  Reserve  Amount may not be amended,
                without the written  consent of the Agent and Lenders holding at
                least  sixty-six  and  two  thirds  percent  (66  2/3%)  of  the
                outstanding  principal  amount of the Notes on such date, and if
                no such principal is  outstanding,  the Lenders whose  aggregate
                Revolving Credit Commitments  constitutes at least sixty-six and
                two  thirds  percent  (66  2/3%) of the Total  Revolving  Credit
                Commitment;

        (vii)   the amount of the Agent's  Fee  payable for the Agent's  account
                and ss.15 may not be amended  without the written consent of the
                Agent;  and the  amount of any fees in  respect  of  Letters  of
                Credit payable for the Issuing Bank's account may not be amended
                without the written consent of the Issuing Bank;

        (viii)  no such amendment,  modification,  waiver or release which would
                release any  Collateral  (except any permitted  asset sale under
                ss.9.5 or as otherwise expressly permitted in this Agreement and
                the  other  Loan  Documents)  from  the  lien  of  the  Security
                Documents shall be effective without the written consent of each
                Lender;

        (ix)    no such amendment,  modification,  waiver or release which would
                have the effect of reducing the principal  amount of any Loan of
                any Lender  shall be  effective  without the written  consent of
                each Lender affected thereby.

No waiver  shall  extend to or affect any  obligation  not  expressly  waived or
impair any right consequent  thereon.  No course of dealing or delay or omission
on the part of the Agent or any Lender in exercising  any right shall operate as
a waiver  thereof or otherwise be  prejudicial  thereto.  No notice to or demand
upon any of the Borrowers shall entitle any of the Borrowers to other or further
notice or demand in similar or other circumstances.

     (b) Notwithstanding anything to the contrary contained in clause (a) above,
the Agent may (i) enter into amendments to the Security Documents or Replacement
Security  Documents,  as the case may be, for the  purpose of adding  additional
Subsidiaries  of the  Borrowers as parties  thereto and (ii) enter into security
documents  to satisfy the  requirements  of  ss.ss.8.15  and 8.17,  in each case
without the consent of the Majority Lenders.


                                      -94-


     (c) Notwithstanding anything to the contrary contained above in this ss.26,
Schedules 7.19, 7.20 and 7.21 may be supplemented or amended and restated by the
Borrowers in connection with any Permitted Acquisition,  to the extent that such
supplement or amendment and restatement  reflects  changes that are permitted by
this Credit Agreement and the other Loan Documents. Such supplement or amendment
and restatement shall become effective upon the Borrowers'  delivery of the same
to the Agent,  together with a certificate  of an Authorized  Officer of Century
Aluminum that such supplement or amendment and restatement reflects changes that
are permitted by this Credit  Agreement and the other Loan Documents.  The Agent
shall promptly  distribute to each Lender a copy of such supplement or amendment
and  restatement,  together with the  certificate of the  Authorized  Officer of
Century Aluminum referred to above.

                                27. SEVERABILITY.

     The provisions of this Credit Agreement are severable and if any one clause
or provision  hereof shall be held invalid or  unenforceable in whole or in part
in any jurisdiction,  then such invalidity or unenforceability shall affect only
such clause or provision,  or part thereof, in such jurisdiction,  and shall not
in any manner affect such clause or provision in any other jurisdiction,  or any
other clause or provision of this Credit Agreement in any jurisdiction.



     IN  WITNESS  WHEREOF,  the  undersigned  have  duly  executed  this  Credit
Agreement as a sealed instrument as of the date first set forth above.
