Determination  Date with respect to a Eurodollar Rate Loan, the rate obtained by
dividing (i) the  Eurodollar  Rate on such Interest Rate  Determination  Date by

supplemental, special or other reserves) applicable generally to any member bank
of the  Federal  Reserve  System in respect  of  "Eurocurrency  liabilities"  as
defined  in  Regulation  D (or  any  successor  category  of  liabilities  under

line of the Federal Reserve Bank of New York (which rate will, under the current
practices  of the Board,  be published in Federal  Reserve  Statistical  Release

be conclusive  absent manifest error) that it is unable to ascertain the Base CD
Rate or the Federal Funds  Effective Rate or both for any reason,  including the
inability of Administrative Agent to obtain sufficient  quotations in accordance
with the terms  thereof,  the Alternate  Base Rate shall be  determined  without
regard to clause (b) or (c), or both, of the first sentence of this  definition,

U.S.  Borrower notice of any such changes promptly after the Alternate Base Rate
changes; provided, however, that the failure to

give such notice shall not limit or otherwise  affect the obligations of Company
or any Borrower under this Agreement or any other Loan Document.

                  As to any loan, the Prime Rate and the Alternate Base Rate are
reference rates that vary from time to time and do not necessarily represent the
lowest or best rate actually charged to any customer by Administrative  Agent or
any U.S. Lender for loans denominated in Dollars.  Administrative Agent and U.S.
Lenders may make commercial loans or other loans denominated in Dollars at rates
of interest at, above or below the Prime Rate or the  Alternate  Base Rate.  The
Alternate Base Rate shall automatically change upon any date that Administrative
Agent  announces any change in its applicable  prime rate or determines that the
interest  rates set forth in clauses  (b) and (c) in the first  sentence of this
definition have changed, to the extent necessary to reflect any such change.

long-term Indebtedness for borrowed money of Company):


      Category            S&P/Moody's Rating                      Percentage
         1                BBB+/Baa1                                  0.40%

                  For purposes of the foregoing,  (i) if neither Moody's nor S&P
shall  have in  effect a  rating  for the  senior  or  subordinated,  unsecured,
non-credit enhanced, long-term Indebtedness for borrowed money of Company (other
than by reason of the  circumstances  referred  to in the last  sentence of this
definition),  then the  Applicable  Margin shall be based on Category 6; (ii) if
only one of  Moody's  and S&P shall  have in effect a rating  for the  senior or
subordinated,   unsecured,   non-credit  enhanced,  long-term  Indebtedness  for
borrowed money of Company, then the

ratings established or deemed to have been established by Moody's or S&P for the
senior or subordinated,  unsecured, long-term Indebtedness for borrowed money of
Company shall fall within different  Categories,  the Applicable Margin shall be
based on the Category corresponding to the lower rating (higher percentage); and
(iv) if any rating  established or deemed to have been established by Moody's or
S&P shall be changed (other than as a result of a change in the rating system of
Moody's or S&P),  such change  shall be  effective as of the date on which it is
first announced by the applicable  rating agency.  Each change in the Applicable
Margin shall apply during the period  commencing on the  effective  date of such
change and ending on the date  immediately  preceding the effective  date of the
next such change. If the rating system of Moody's or S&P shall change, or if any
such rating  agency shall cease to be in the business of rating  corporate  debt
obligations,  Company and  Lenders  shall  negotiate  in good faith to amend the
references to specific ratings in this definition to reflect such changed rating
system or the  non-availability  of ratings from such rating agency, and pending
the effectiveness of any such amendment,  the ratings of such rating agency most
recently  in effect  prior to such  change or  cessation  shall be  employed  in
determining the Applicable Margin.

                  subsection  2.1B (or  telephonic  notice in lieu thereof) from
                  U.S.  Borrower,  Administrative  Agent shall 


                                       40




                  notify each U.S.  Lender of the proposed  borrowing  and the
                  details  thereof.  Each U.S. Lender shall make the amount of
                  its Loan  (other  than any Gold  Loan to be  funded in Gold)
                  available  in  Dollars to  Administrative  Agent in same day
                  funds at  Administrative  Agent's  Lending  Office not later

                  applicable  Funding  Date  to  the  Administrative   Agent's
                  account with J.P.  Morgan,  London,  England,  or such other
                  London   bullion   account   as   may   be   designated   by

                  time  not  later  than  three  Business  Days  prior  to the
                  applicable  Funding Date. Upon satisfaction or waiver of the
                  conditions  precedent  specified in subsections  3.1 (in the
                  case of the  initial  Loans)  and  3.2  (in the  case of all
                  Loans), Administrative Agent shall make the proceeds of such
                  Loans in Dollars or Gold,  as the case may be,  available to
                  U.S.  Borrower on the applicable  Funding Date by (a) in the
                  case of Loans in  Dollars,  causing  an  amount  of same day

                  Administrative Agent from U.S. Lenders to be credited to the
                  U.S.  Borrower  Account  or (b) in the  case of Gold  Loans,
                  either  (1)  advancing  the Dollar  Equivalent  of such Gold
                  Loans,  which shall be calculated based on the Price of Gold
                  as in  effect  on the  second  Business  Day  preceding  the
                  applicable  Funding Date,  and causing an amount of same day
                  funds  equal to such amount of Dollars to be credited to the
                  U.S.  Borrower Account or (2) effecting the Delivery of Gold
                  comprising  such Gold  Loans to a location  mutually  agreed
                  upon by U.S. Borrower and Administrative Agent and set forth
                  in the Notice of Borrowing.

                  (iv) Failure to Fund Loans. No Lender shall be responsible for
                  any  default  by any  other  Lender  in  that  other  Lender's
                  obligation  to make a Loan  requested  hereunder nor shall the
                  Commitment of any Lender to make the  particular  type of Loan
                  requested  be  increased or decreased as a result of a default
                  by any other Lender in that other Lender's  obligation to make
                  a   Loan   requested   hereunder.    Unless   the   Applicable
                  Administrative  Agent  shall have been  notified by any Lender
                  prior to the  Funding  Date for any Loans to be funded by such
                  Lender that such Lender does not intend to make  available  to
                  the  Applicable   Administrative  Agent  the  amount  of  such
                  Lender's Loan  requested on such Funding Date,  the Applicable
                  Administrative Agent may assume that such Lender has made such
                  amount  available to the  Applicable  Administrative  Agent on
                  such Funding Date and the Applicable Administrative Agent may,
                  in its sole  discretion,  but shall not be obligated  to, make
                  available to the applicable Borrower a corresponding amount on
                  such Funding Date. If such corresponding amount is not in fact
                  made available to the Applicable  Administrative Agent by such
                  Lender, the Applicable  Administrative Agent shall be entitled
                  to  recover  such  corresponding  amount on  demand  from such
                  Lender together with interest thereon,  for each day from such
                  Funding  Date  until  the  date  such  amount  is  paid to the
                  Applicable  Administrative Agent, at the customary rate set by
                  the  Applicable  Administrative  Agent for the  

                                       41



                    correction of errors among banks for three Business Days and
                    thereafter  at the Canadian Base Rate plus 1.0% or, if less,
                    at the  customary  rate set by the  Canadian  Administrative
                    Agent for the correction of errors among banks,  in the case
                    of any Canadian  Dollar Loan,  the Bank Bill Swap Rate for a
                    one month  Interest  Period,  in the case of any  Australian
                    Dollar Loans,  the  Alternate  Base Rate, in the case of any
                    Dollar Loan made by any U.S.  Lender or  Australian  Lender,
                    the U.S. Base Rate (Canada),  in the case of any Dollar Loan
                    made by any Canadian Lender, or the applicable Gold Rate, in
                    the case of any Gold Loan.  If such Lender does not pay such
                    corresponding   amount   forthwith   upon   the   Applicable
                    Administrative   Agent's  demand  therefor,  the  Applicable
                    Administrative  Agent shall  promptly  notify the applicable
                    Borrower  and  such  Borrower  shall  immediately  pay  such
                    corresponding amount to the Applicable  Administrative Agent
                    together  with  interest  thereon,  for each  day from  such
                    Funding  Date  until  the date  such  amount  is paid to the
                    Applicable Administrative Agent, at the rate then applicable
                    to  Canadian  Base Rate Loans plus 1.0% or, if less,  at the
                    customary rate set by the Canadian  Administrative Agent for
                    the  correction  of errors among  banks,  in the case of any
                    Canadian  Dollar Loan, the rate then  applicable to the Bank
                    Bill Rate Swap Loans for a one month Interest  Period in the
                    case of any Australian Dollar Loan, the rate then applicable
                    to Base Rate  Loans,  in the case of any Dollar  Loan or the
                    applicable  Gold Rate,  in the case of any Gold Loan. In all
                    of the foregoing instances,  such interest in respect of any
                    Gold  Loan  shall  be  payable  in  Dollars   and  shall  be
                    calculated  daily  in  accordance  with  the  provisions  of
                    subsection  2.2F.  Nothing in this  subsection 2.1C shall be
                    deemed to relieve any Lender from its  obligation to fulfill
                    its  commitments  hereunder or to prejudice  any rights that
                    any  Borrower may have against any Lender as a result of any
                    default by such Lender hereunder.

                  (v) Confirmation of Delivery,  Risk of Loss, Delivery Charges.
                  Unless the Administrative  Agent receives notice from the U.S.
                  Borrower within seven Business Days of U.S. Borrower's receipt
                  of any Gold,  the quantity and quality of the Gold so received
                  shall  be  deemed  to be as set  forth  in the  Administrative
                  Agent's  delivery  order.  If there is any  discrepancy in the
                  amount or quality of Gold  actually  Delivered,  the amount of
                  such  difference  shall be settled  in  Dollars  (based on the
                  Dollar Equivalent on the date of Delivery of the Gold required
                  to be  advanced  hereunder  and the Gold  actually  Delivered)
                  promptly after the Delivery thereof. U.S. Borrower assumes all
                  risk of loss,  theft or  detention  of or  damage  to any Gold
                  Delivered  hereunder  from the  date  U.S.  Borrower  receives
                  Delivery of such Gold until the date of its return by Delivery
                  to the Administrative Agent. U.S. Borrower shall pay all costs
                  and  charges  (including  costs and  expenses  of  collection,
                  shipment,   cartage,   warehousing,    packaging,    refining,
                  converting or insurance and any applicable  location premiums)
                  directly relating to the physical Delivery of Gold pursuant to
                  this  Agreement  incurred on and after request for Delivery of
                  Gold by U.S. Borrower until return of Gold by U.S. Borrower at
                  the required location.

                                       42


                  D. Note  Option.  If so  requested  by any  Lender by  written
notice to the applicable  Borrower (with a copy to  Administrative  Agent),  the
Borrower to whom such  request is made shall  execute and deliver to such Lender
(within  three  Business  Days of such  Borrower's  receipt  of such  notice)  a
promissory note  substantially  in the form of Exhibit IV-A to this Agreement to
evidence such Lender's  Canadian  Loans,  in the form of Exhibit IV-B or Exhibit
IV-C to this Agreement to evidence such Lender's  Australian  Loans, in the form
of Exhibit IV-D to this  Agreement to evidence such  Lender's U.S.  Loans (other
than Gold  Loans),  or a Grid Gold  Acknowledgement  in the form of Exhibit V to
this Agreement to evidence such Lender's Gold Loans.

                  E. Risk  Participations.  The  Lenders  intend  that  after an
acceleration  of the  Obligations  pursuant  to  Section  7, the  ratio for each
Lending Unit of the aggregate  Exposure of the Borrowers to such Lending Unit to
the  aggregate  Exposure of the  Borrowers to all Lending Units shall equal such
Lending Unit's Pro Rata Share. Accordingly, immediately upon the acceleration of
the Obligations  pursuant to Section 7, each Canadian Loan, each Australian Loan
and each Obligation  relating  thereto shall be deemed to be a Dollar Loan in an
amount equal to the Dollar Equivalent of such Canadian Loan, Australian Loans or
other Obligations, as applicable, and accordingly the liability of the Borrowers
to pay and the right of the Lenders to receive  payment of all  Canadian  Loans,
Australian  Loans and Obligations  relating thereto shall thereupon be to pay or
to receive, respectively, Dollar in the amounts so determined. At such time, the
Administrative  Agent shall determine for which Lending Units, if any, the ratio
of the aggregate Exposure of the Borrowers to such Lending Unit to the aggregate
Exposure of the Borrowers to all Lending Units is less than such Lending  Unit's
Pro Rata Share (such Lending Unit is herein called  "Purchasing  Lending Unit"),
and for which Lending Units, if any, the ratio of the aggregate  exposure of the
Borrowers to such Lending Unit to the aggregate Exposure of the Borrowers to all
Lending  Units is greater than such Lending  Unit's Pro Rata Share (such Lending
Unit  is  herein  called  a  "Selling   Lending   Unit).   Promptly  after  such
determination is made,  notwithstanding  the allocation of the Commitment of any
Lending Unit as among the Canadian Commitments,  the Australian  Commitments and
the U.S.  Commitments,  each  Purchasing  Lending Unit shall  purchase  from the
Selling  Lending  Units,  and  each  Selling  Lending  Unit  shall  sell to each
Purchasing  Lending Unit,  for cash and without  representation  or warranty,  a
portion  of the  outstanding  Loans  from  such  Selling  Lending  Unit,  and if
necessary to achieve the objective of this Section, each Purchasing Lending Unit
shall also purchase risk  participations in respect of a portion of such Selling
Lending Unit's liability for outstanding Bankers' Acceptances, Letters of Credit
and Gold Loans, such that each Lending Unit's share of the aggregate Exposure of
the Borrowers shall equal its Pro Rata Share. The amounts and particulars of the
purchases and sales of the Loans,  Bankers'  acceptances,  Letters of Credit and
Gold Loans for the purpose of the foregoing  arrangements shall be determined in
each case by the  Administrative  Agent upon  consultation  with the  applicable
Lending Units, and the administrative  Agent shall have the power to execute any
documentation  as attorney for any Lender in order to complete  any  transaction
required by this Section.  The foregoing  arrangements may require a Borrower to
make  payments  pursuant to Section 10.7 that it would not have been required to
make in the absence of such arrangements.

2.2      Interest on the Loans.

                                       43


                  A. Rate of Interest.  Subject to the provisions of subsections
2.6 and 10.7,  each Loan shall bear  interest  on the  unpaid  principal  amount
thereof  from the  date  made  through  maturity  (whether  by  acceleration  or
otherwise) at a rate  determined  by reference to: (i) the Alternate  Base Rate,
the U.S. Base Rate (Canada), the Eurodollar Rate or the Adjusted Eurodollar Rate
in the case of any Dollar Loan;  (ii) the Canadian  Base Rate in the case of any
Canadian Dollar Loan; (iii) the Bank Bill Swap Rate in the case of an Australian
Dollar Loan; or (iv) the Gold Rate in the case of any Gold Loan.  The applicable
basis for  determining  the rate of interest  with  respect to any Loan shall be
selected by the applicable  Borrower initially at the time a Notice of Borrowing
is given with respect to such Loan  pursuant to subsection  2.1B.  The basis for
determining  the interest rate with respect to any Loan may be changed from time
to time pursuant to subsection 2.2D.

Loans shall bear interest through maturity as follows:

                  (i)      if a U.S. Base Rate Loan, then at the Alternate Base 
                  Rate per annum;

                  (iv) if a Bank  Bill Swap  Rate  Loan,  then at the sum of the
                  Bank Bill Swap Rate plus the Applicable Margin per annum;

                  (v) if a  Eurodollar  Rate  Loan  that  is a U.S.  Loan  or an

may,   pursuant   to  the   applicable   Notice  of   Borrowing   or  Notice  of
Conversion/Continuation,  as the case may be,  select an  Interest  Period to be
applicable to such Loan; provided that:

                  (i) the initial  Interest Period for any Eurodollar Rate Loan,
                  Bank Bill Swap Rate Loan,  or Gold Loan shall  commence on the
                  Funding  Date of such  Loan,  in the case of a Loan  initially
                  made as a Eurodollar Rate Loan, a Bank Bill Swap Rate Loan, or
                  a Gold Loan, or on the date specified in the applicable Notice
                  of Conversion/Continuation,  in the case of any Loan converted
                  into a Eurodollar Rate Loan;


                                       44


                  (ii) in the case of immediately  successive  Interest  Periods
                  applicable to any  Eurodollar  Rate Loan,  Bank Bill Swap Rate
                  Loan,  or Gold Loan  continued as such pursuant to a Notice of
                  Conversion/Continuation,  each such successive Interest Period
                  shall  commence  on the day on which  the  preceding  Interest
                  Period expires;

                  (iii) if an Interest  Period would  otherwise  expire on a day
                  that is not a Business Day, such Interest  Period shall expire
                  on the next  succeeding  Business Day;  provided  that, in the
                  case of a Eurodollar  Rate Loan, if any Interest  Period would
                  otherwise  expire on a day that is not a Business Day but is a
                  day of the month after which no further Business Day occurs in
                  such month,  such  Interest  Period  shall  expire on the next
                  preceding Business Day;

                  (iv) any  Interest  Period  for a  Eurodollar  Rate  Loan that
                  begins on the last  Business Day of a calendar  month (or on a
                  day for which there is no numerically corresponding day in the
                  calendar  month  at the end of such  Interest  Period)  shall,
                  subject to clause (v) of this subsection 2.2B, end on the last
                  Business Day of a calendar month;

                  (v) no Interest  Period with  respect to any Loan shall extend
                  beyond the Commitment Termination Date; and

                  (vi)  there  shall  be no  more  than  five  Interest  Periods
                  relating to  Eurodollar  Rate Loans  outstanding  at any time,
                  there shall be no more than five Interest  Periods relating to
                  Bank Bill Swap Rate  Loans  outstanding  at any time and there
                  shall be no more than five Interest  Periods  relating to Gold
                  Loans outstanding at any time.

                  C. Interest Payments; Currencies. Subject to the provisions of
subsection  2.2E,  interest  on each Loan  shall be payable in arrears on and to
each Interest  Payment Date applicable to that Loan, upon any prepayment of that
Loan (to the extent  accrued on the amount being  prepaid) and at maturity.  All
payments of interest  shall be paid to the  Applicable  Administrative  Agent in
accordance with the provisions of subsection 2.4B.

                  Interest  payable on any Loan  denominated in a currency shall
be  payable  in the same  currency.  Interest  payable on any Gold Loan shall be
payable,  at U.S.  Borrower's  option,  in (a) Gold or (b)  Dollars  in  amounts
determined in accordance with the provisions of 2.2F. U.S. Borrower shall advise
Administrative  Agent of its  intention to pay interest on Gold Loans in Gold in
the  applicable  Notice  of  Borrowing  or  Notice  of  Conversion/Continuation;
provided that  Administrative  Agent shall,  notwithstanding any request of U.S.
Borrower to pay such  interest in Gold,  have the right to require that interest
with  respect to any Gold Loan be paid in  Dollars by notice  given on or before
the related Funding Date in the case of the initial Interest  Period,  and prior
to the date of  continuation,  in the case of a continuation.  If U.S.  Borrower
fails  timely  to  advise  Administrative  Agent of its  desire  to pay  accrued
interest  in Gold,  U.S.  Borrower  shall be deemed to have  elected to pay such
interest in Dollars.

                  D.  Conversion or  Continuation.  Subject to the provisions of
subsection 2.6, (i) each of U.S.  Borrower and Canadian  Borrower shall have the
option to convert at any time all 

                                       45


or any part of its  outstanding  Dollar Loans equal to  $5,000,000  and integral
multiples  of  $1,000,000  in excess of that amount from  Dollar  Loans  bearing
interest at a rate  determined by reference to one basis to Dollar Loans bearing
interest at a rate  determined by reference to an alternative  basis,  (ii) each
Borrower  shall have the option,  upon the  expiration  of any  Interest  Period
applicable  to a  Eurodollar  Rate Loan,  to continue all or any portion of such
Eurodollar Rate Loan equal to $5,000,000 and integral multiples of $1,000,000 in
excess of that amount as a  Eurodollar  Rate Loan,  (iii)  Australian  Borrowers
shall have the option,  upon the expiration of any Interest Period applicable to
a Bank Bill Swap Rate Loan,  to  continue  all or any  portion of such Bank Bill
Swap Rate Loan equal to  A$5,000,000  and integral  multiples of  A$1,000,000 in
excess of that amount as a Bank Bill Swap Rate Loan,  (iv) U.S.  Borrower  shall
have the option, upon the expiration of any Interest Period applicable to a Gold
Loan,  to continue  all or any portion of such Gold Loan equal to 10,000  Ounces
and integral  multiples of 2,000 Ounces in excess of that amount as a Gold Loan;
provided, however, that a Eurodollar Rate Loan may only be converted into a U.S.
Base  Rate  Loan or a U.S.  Base  Rate  (Canada)  Loan,  as  applicable,  on the
expiration date of an Interest Period applicable thereto; provided further that,
subject to the  following  proviso,  no Loan may be made as or converted  into a
U.S.  Base Rate Loan or a U.S.  Base Rate  (Canada)  Loan during the period from
December 24 of any year to and including January 7 of the immediately succeeding
year for the  purpose of  investing  in  securities  bearing  interest at a rate
determined  by  reference  to any other  basis for the purpose of  arbitrage  or
speculation;  and provided still further that no Loan may be converted  into, or
continued  as, a  Eurodollar  Rate Loan (except that  Australian  Borrowers  may
continue  Eurodollar Rate Loans with a period of one month), or a Bank Bill Swap
Rate Loan with a period in excess of one month,  or a Gold Loan at any time that
a  Potential  Event of  Default  or an  Event of  Default  has  occurred  and is
continuing.

                  The   applicable   Borrower   shall   deliver   a  Notice   of
Conversion/Continuation  (i) in the case of a  conversion  to a U.S.  Base  Rate
Loan, to Administrative  Agent no later than 12:00 Noon (New York time) at least
one Business Day in advance of the proposed  conversion/continuation  date, (ii)
in the case of a conversion  to, or a  continuation  of, a Eurodollar  Rate Loan

Administrative  Agent no later  than  11:00  A.M.  (Toronto  time) at least  one
Business Day in advance of the proposed conversion/continuation date, (v) in the
case of a continuation of a Eurodollar  Rate Loan made to Australian  Borrowers,
or a continuation of a Bank Bill Swap Rate Loan made to Australian Borrowers, to
Australian  Administrative  Agent and  Administrative  Agent no later than 12:00
Noon  (Sydney  time) at least  three  Business  Days in advance of the  proposed

(which  shall  be  a  Business  Day),  (iii)  the  amount  of  the  Loan  to  be
converted/continued,  (iv) the nature of the  proposed  conversion/continuation,
(v) in the case of a conversion to or a continuation  of a Eurodollar  Rate Loan
or a  continuation  of a Bank Bill Swap Rate Loan or a Gold Loan,  the requested
Interest 


                                       46


Period,  (vi) in the case of the  continuation of a Gold Loan,  whether
U.S.  Borrower  is  requesting  to pay  interest  in Dollars or in Gold,  and if
payable in Dollars, the basis for calculating the amount according to one of the
alternatives specified in subsection 2.2F, and (vii) in the case of a conversion
to or a continuation of a Eurodollar Rate Loan (except by Australian  Borrowers)
or a continuation of a Gold Loan, that no Potential Event of Default or Event of
Default  has   occurred  and  is   continuing.   In  lieu  of   delivering   the
above-described Notice of  Conversion/Continuation,  the applicable Borrower may
give  Administrative  Agent and the Applicable  Administrative  Agent telephonic
notice by the required time of any proposed  conversion/continuation  under this
subsection  2.2D;  provided  that such  notice  shall be promptly  confirmed  in
writing by delivery  of a Notice of  Conversion/Continuation  to  Administrative
Agent  and  the  Applicable  Administrative  Agent  on or  before  the  proposed
conversion/continuation date.

                  Neither any Agent nor any Lender shall incur any  liability to
any  Borrower  in acting  upon any  telephonic  notice  referred  to above  that
Administrative  Agent or the  Applicable  Administrative  Agent believes in good
faith to have been given by a duly authorized officer or other person authorized
to act on behalf of such  Borrower or for  otherwise  acting in good faith under
this  subsection  2.2D, and upon  conversion or  continuation  of the applicable
basis for  determining the interest rate with respect to any Loans in accordance
with this Agreement pursuant to any such telephonic notice,  such Borrower shall
have effected a conversion or continuation, as the case may be, hereunder.

                  Except as otherwise  provided in  subsections  2.6B,  2.6C and
2.6G, a Notice of Conversion/Continuation  for conversion to, or continuation of
a Eurodollar Rate Loan or a continuation of a Bank Bill Swap Rate Loan or a Gold
Loan (or telephonic notice in lieu thereof) shall be irrevocable when given, and
the Borrower delivering such Notice of Conversion/Continuation shall be bound to
effect a conversion or continuation in accordance therewith.

                  If   any    Borrower    fails   to    submit   a   Notice   of
Conversion/Continuation  with respect to any maturing  Eurodollar  Rate Loans or
Bank Bill Swap Rate Loans in  accordance  with the forgoing  provisions  of this
subsection  2.2D,  then upon the  expiration  of the  Interest  Period  for such
Eurodollar  Rate Loans or Bank Bill Swap Rate Loans,  as applicable,  such Loans
shall (i) if no Event of  Default  or  Potential  Event of  Default  shall  have
occurred and be continuing,  automatically  continue as Eurodollar Rate Loans or
Bank Bill Swap Rate Loans,  as applicable,  in each case with an Interest Period
of one month and (ii) if an Event of Default or Potential Event of Default shall
have occurred and be continuing,  automatically be converted into U.S. Base Rate
Loans or U.S. Base Rate (Canada) Loans, as applicable, in the case of U.S. Loans
and Canadian  Loans, or continue as Eurodollar Rate Loans or Bank Bill Swap Rate
Loans with an Interest  Period of one month in the case of Australian  Loans. If
U.S. Borrower fails to submit a Notice of  Conversion/Continuation  with respect
to any maturing  Gold Loans in accordance  with the forgoing  provisions of this
subsection  2.2D,  then upon the expiration of the Interest Period for such Gold
Loans, such Loans shall automatically be continued as Gold Loans having a 30-day
Interest Period. Upon the continuation (including automatic continuation) of any
Loan,  the  Applicable   Administrative  Agent  shall  notify  Company  and  the
applicable Borrower of such continuation; provided, however, that the failure to
give such notice shall not limit or otherwise

                                       47



affect the  obligations  of Company or any Borrower  under this Agreement or any
other Loan Document.

                  E. Post-Maturity Interest. Any principal payments on the Loans
not paid when due and, to the extent  permitted by applicable  law, any interest
payments on the Loans owed  hereunder not paid when due, in each case whether at
stated maturity,  by notice of prepayment,  by acceleration or otherwise,  shall
thereafter  bear interest  (including  post-petition  interest in any proceeding
under the Bankruptcy Code or other applicable bankruptcy laws) payable on demand
at a rate which is 2% per annum in excess of the interest rate otherwise payable
under  this  Agreement  in  respect of such Loans (or in the case of any fees or
other  amounts,  a rate  which is 2% per annum in excess  of the  interest  rate
otherwise payable under this Agreement for U.S. Base Rate Loans); provided that,
in the case of Eurodollar  Rate Loans or Gold Loans,  upon the expiration of the
Interest  Period in effect at the time any such  increase  in  interest  rate is
effective,  such Eurodollar Rate Loans or Gold Loans (in the case of Gold Loans,
by  converting  the  outstanding  amount of such Loans into Dollars based on the
Price of Gold as in effect on such expiration  date) shall thereupon become U.S.
Base Rate Loans or U.S.  Base Rate  (Canada)  Loans,  as  applicable,  and shall
thereafter bear interest  payable upon demand at a rate which is 2% per annum in
excess of the interest rate otherwise  payable under this Agreement at such time
for U.S.  Base Rate Loans or U.S.  Base Rate (Canada)  Loans,  respectively,  as
applicable,  except that in the case of Australian  Borrowers,  such  Eurodollar
Rate Loans shall be continued as Eurodollar  Rate Loans with an Interest  Period
of one  month,  and  provided  further  that in the case of Bank  Bill Swap Rate
Loans,  such Bank Bill Swap Rate  Loans  shall  continue  as Bank Bill Swap Rate
Loans  with an  Interest  Period of one  month.  Payment  or  acceptance  of the
increased  rates  of  interest  provided  for in this  subsection  2.2E is not a
permitted alternative to timely payment and shall not constitute a waiver of any
Event of Default or  otherwise  prejudice or limit any rights or remedies of any
Agent or any Lender.

                  F. Computation of Interest.  Interest on the Loans denominated
in currency shall be computed, in the case of Base Rate Loans and Bank Bill Swap
Rate Loans, on the basis of a 365-day or 366-day year, as the case may be, or in
the case of Eurodollar  Rate Loans, on the basis of a 360-day year, in each case
for the actual number of days elapsed in the period during which it accrues, and
shall be determined  daily with respect to the amount of such Loans  outstanding
each day during such period. Interest on each Gold Loan shall be computed on the
basis of a 360-day  year and the  actual  number of days  elapsed  in the period
during  which it  accrues  and  shall  be  determined  daily  (i) in the case of
interest  to be paid in Gold,  with  respect  to the  number  of  Ounces of Gold
outstanding  under such Gold Loan on each day during such period, or (ii) in the
case of interest to be paid in Dollars, with respect to the average of the daily
values  (such  values  being  equal to the  number  of  Ounces of such Gold Loan
multiplied  by the  Price of Gold) of such  Gold  Loan,  in  Dollar  Equivalents
(determined  daily unless U.S.  Borrower  requests in its Notice of Borrowing or
Notice of  Conversion/Continuation  that the Price of Gold be fixed at the Price
of Gold on the second Business Day prior to the related  Interest Period for the
purpose of determining  accrued  interest during the applicable  Interest Period
and Requisite  Lenders have not objected on or before the  commencement  of such
Interest  Period,  in their sole  discretion,  to use such fixed  price for such
purpose  during such  period),  for each day during such  period.  In  computing
interest on any Loan, the date of the making of such Loan or the first day of an
Interest  


                                       48


Period  applicable  to such  Loan or,  with  respect  to a Loan  being
converted from a Eurodollar Rate Loan, the date of conversion of such Eurodollar
Rate  Loan,  shall be  included,  and the date of  payment  of such  Loan or the
expiration date of an Interest  Period  applicable to such Loan or, with respect
to a Loan being  converted to a Eurodollar  Rate Loan, the date of conversion to
such Eurodollar Rate Loan, shall be excluded;  provided that if a Loan is repaid
on the same day on which it is made,  one day's  interest  shall be paid on that
Loan.

                  For the  purposes  of this  Agreement,  whenever  interest  is
calculated on the basis of a year of 360 days, each rate of interest  determined
pursuant to such calculation expressed as an annual rate for the purposes of the
Interest Act (Canada) is equivalent to such rate as so determined  multiplied by
the  actual  number  of days in the  calendar  year in  which  the same is to be
ascertained and divided by 360.

2.3      Fees.

                  A. Commitment Fees.  Borrowers  jointly and severally agree to
pay to  Administrative  Agent (i) for distribution to each Canadian  Lender,  in
proportion  to that  Lender's  Canadian  Lender Pro Rata  Share of the  Canadian
Allocation,  commitment fees for the period from and after the Effective Date to
and excluding the Commitment Termination Date, equal to the quarterly average of
the daily excess of the Canadian  Allocation over the Canadian  Commitment Usage
(in Dollar Equivalents)  multiplied by the applicable  Commitment Fee Percentage
per annum,  (ii) for  distribution to each Australian  Lender,  in proportion to
that Lender's  Australian  Lender Pro Rata Share of the  Australian  Allocation,
commitment  fees  for the  period  from  and  after  the  Effective  Date to and
excluding the Commitment  Termination Date equal to the quarterly average of the
daily excess of the Australian  Allocation over the Australian  Commitment Usage
(in Dollar Equivalents)  multiplied by the applicable  Commitment Fee Percentage
per annum, and (iii) for distribution to each U.S. Lender, in proportion to that
Lender's U.S. Lender Pro Rata Share of the U.S. Allocation,  commitment fees for
the period from and after the Effective  Date to and  excluding  the  Commitment
Termination Date, equal to the quarterly average of the daily excess of the U.S.
Allocation  over  the  U.S.   Commitment  Usage  multiplied  by  the  applicable
Commitment Fee Percentage per annum;  all such  commitment fees to be payable in
Dollars, quarterly in arrears on March 1, June 1, September 1, and December 1 of
each year and on the  Commitment  Termination  Date and to be  calculated on the
basis of a 360-day year and the actual  number of days  elapsed;  provided  that
notwithstanding  the  foregoing,  the  commitment  fees payable to each Canadian
Lender shall be paid to the Canadian  Administrative  Agent.  Reductions  in the
amounts available for borrowing under the Commitments arising from the operation
of the  limitations  set forth in clauses (a), (b), (c), (d), (e), (f) (g), (h),
(i) and (j) of subsection 2.1A(v) shall not constitute usages of Commitments for
purposes  of this  subsection  2.3A and  shall  not  reduce  the  amount  of the
commitment fees that are payable under this subsection 2.3A.

                  B.  Other  Fees.   Company  and  Borrowers  agree  to  pay  to
Administrative  Agent,  Arranger and Issuing  Lenders the fees agreed to, and in
the amounts and at the times,  set forth in writing  among  Company,  Borrowers,
Administrative Agent, Arranger and Issuing Lenders.

                  Administrative  Agent and  Administrative  Agent (which notice
                  the Applicable  Administrative Agent will promptly transmit by
                  telecopy,  telegram,  telex or telephone to each U.S.  Lender,
                  Canadian Lender or Australian Lender, as appropriate),  at any
                  time and from  time to time  prepay  any  Loans in whole or in
                  part on any Business Day (a) in an aggregate minimum amount of
                  $2,500,000  and  integral  multiples  of $500,000 in excess of
                  that amount in the case of Dollar  Loans,  (b) in an aggregate
                  minimum  amount of  Cdn.$2,500,000  and integral  multiples of

                  that amount in the case of Australian  Dollar Loans, or (d) in
                  an  aggregate  minimum  amount of 10,000  Ounces and  integral
                  multiples of 2,000 Ounces in excess of that amount in the case

                  Loan,  a Bank Bill Swap Rate Loan or a Gold Loan is prepaid on
                  a  date  other  than  the  last  day of  the  Interest  Period
                  applicable thereto,  the Borrower making such prepayment shall
                  be liable for any payments required by subsection 2.6D. Notice
                  of prepayment  having been given as  aforesaid,  the principal
                  amount of the Loans  specified in such notice shall become due
                  and payable on the prepayment date specified therein. Any such
                  voluntary   prepayment   shall  be  applied  as  specified  in
                  subsection 2.4A(iv).

                  (ii) Voluntary Reductions of Commitments.  Borrowers may, upon
                  not less than three  Business  Days' prior  written  notice to
                  Administrative  Agent (which notice  Administrative Agent will
                  promptly transmit by telecopy, telegram, telex or telephone to
                  each Lender),  at any time and from time to time  terminate in
                  whole or  permanently  reduce  in  part,  without  premium  or
                  penalty, the Overall Commitments in an amount up to the amount
                  by which the Overall  Commitments exceed the Total Utilization
                  of  Overall   Commitments   at  the  time  of  such   proposed
                  termination  or  reduction;  provided  that any  such  partial
                  reduction of the Overall  Commitments shall be in an aggregate
                  minimum  amount  of  $2,500,000  and  integral   multiples  of
                  $500,000 in excess of that amount;  and provided  further that
                  no  reduction  shall  reduce the  Canadian  Allocation  to any
                  amount that is less than the Canadian  Commitment  Usage,  the
                  Australian  Allocation  to any  amount  that is less  than the
                  Australian  Commitment  Usage  or the  U.S.  Allocation  to an
                  amount that is less than the U.S. Commitment Usage. Borrowers'
                  notice to Administrative Agent shall designate the date (which
                  shall be a Business Day) of such termination or 


                                       50



                  reduction,  the  amount  of any  partial  reduction  and the
                  allocation of any reduction  among the Canadian  Allocation,
                  the Australian Allocation and the U.S. Allocation,  and such
                  termination or reduction of the Overall Commitments shall be
                  effective  on the date  specified in  Borrowers'  notice and
                  shall   reduce  the   Commitment   of  each   Lending   Unit
                  proportionately  to its Pro  Rata  Share  and  such  partial
                  reduction and allocation of such reduction  shall be made so
                  that (i) the  Australian  Allocation  shall not  exceed  the
                  Australian  Commitment,  (ii) the Canadian  Allocation shall
                  not  exceed  the  Canadian  Commitment  and  (iii)  the U.S.

                  (iii)    Mandatory Prepayments of Loans.

                           (a) If on any date (A) the sum of (1) the outstanding
                  amount of all Loans  denominated in currency (valued in Dollar
                  Equivalents as of the most recent Date of Determination),  (2)
                  the BA Usage plus the Canadian  Letter of Credit Usage (valued
                  in  Dollar   Equivalents   as  of  the  most  recent  Date  of
                  Determination),  (3) the  Australian  Letter of  Credit  Usage
                  (valued in Dollar  Equivalents  as of the most  recent Date of
                  Determination),  (4) the U.S.  Letter of Credit  Usage and (5)
                  the  outstanding  amount of all Gold  Loans  (valued in Dollar
                  Equivalents  based  upon the  Price  of Gold as of such  date)
                  (such sum being the "Aggregate Dollar Equivalent Loan Amount")
                  exceeds the Overall  Commitments  in effect on such date,  (B)
                  the portion of the  Aggregate  Dollar  Equivalent  Loan Amount
                  relating  to  the  Canadian   Borrower  exceeds  the  Canadian
                  Allocation, (C) the portion of the Aggregate Dollar Equivalent
                  Loan Amount relating to the Australian  Borrowers  exceeds the

                  Dollar  Equivalent Loan Amount  relating to the U.S.  Borrower
                  exceeds the U.S.  Allocation,  then, subject to the provisions
                  of the immediately succeeding sentence, Borrowers shall prepay
                  Loans and/or reduce the outstanding BA Usage,  Canadian Letter
                  of Credit Usage,  Australian  Letter of Credit Usage,  or U.S.
                  Letter of Credit Usage (it being agreed and  understood  that,
                  for the  purposes  of this  subsection  2.4A(iii),  BA  Usage,
                  Canadian Letter of Credit Usage,  Australian  Letter of Credit
                  Usage and U.S.  Letter of Credit Usage shall be reduced to the
                  extent that the  applicable  Borrower has cash  collateralized
                  its  reimbursement   obligations  under  outstanding  Bankers'
                  Acceptances  or Letters  of Credit  pursuant  to  arrangements
                  satisfactory  to  Administrative   Agent  and  the  applicable
                  Issuing  Lender)  in an  amount  equal  to  any  such  excess;
                  provided  that if any such  excess  exists,  and to the extent
                  that any such excess  results  from an average net increase of
                  less  than 50% in the  outstanding  amount  of all Gold  Loans
                  (valued in Dollar  Equivalents based upon the Price of Gold as
                  of such  date)  since  the  second  Business  Day prior to the
                  related  Gold  Advance  Dates for such Gold  Loans  because of
                  changes in the Price of Gold,  until the Total  Utilization of
                  Overall  Commitments  equals 125% of the Overall  Commitments,
                  Borrowers  shall not be so  required  to prepay  Loans  and/or
                  reduce the  outstanding  BA Usage,  Canadian  Letter of Credit
                  Usage,  Australian  Letter of Credit  Usage or U.S.  Letter of
                  Credit Usage to such extent.  Notwithstanding  the  foregoing,
                  Borrowers  shall not be  required  to prepay the Gold Loans if

                                       51


                  Borrowers  pledge cash,  U.S.  Treasury  securities or Gold as
                  collateral  to  Administrative  Agent for the  benefit  of the
                  Lenders  in an amount  equal to the  amount of Gold Loans that
                  would  otherwise be required to be prepaid in accordance  with
                  this subsection 2.4A(iii) pursuant to arrangements in form and
                  substance  satisfactory  to  Administrative  Agent.  Any  such
                  mandatory   prepayments  shall  be  applied  as  specified  in
                  subsection 2.4A(iv)(c).

                           (b) Borrowers shall also prepay the Loans as required
                  pursuant to subsection  10.25 upon the occurrence of a Company
                  Change of Control.

                  (iv)     Application of Prepayments.

                          (a)     Application of Voluntary Prepayments.  Any 
                 voluntary  prepayments  by Borrowers  pursuant to subsection
                 2.4A(i)  shall be applied to the Loans of each Borrower as 
                 specified by Borrowers;

                          (b)   Application   of  Mandatory   Prepayments.   Any
                 mandatory  prepayments  by  Borrowers  pursuant  to  subsection
                 2.4A(iii)(b) shall be applied to repay outstanding Loans and to
                 reduce permanently the Overall  Commitments  (allocated ratably
                 to the Canadian Allocation,  the Australian  Allocation and the
                 U.S. Allocation unless otherwise specified by Borrowers); and

                          (c)  Application  of  Prepayments  to Base Rate Loans,
                 Bank Bill  Swap  Rate  Loans and  Eurodollar  Rate  Loans.  Any
                 prepayment by or for the benefit of a Borrower shall be applied
                 first to Base Rate Loans of such  Borrower  to the full  extent
                 thereof  before  application  to Bank Bill Swap Rate  Loans and
                 Eurodollar  Rate  Loans  of such  Borrower,  in each  case in a
                 manner which  minimizes the amount of any payments  required to
                 be made by the applicable Borrower pursuant to subsection 2.6D.

         B.       General Provisions Regarding Payments.

                  (i)  Manner  and Time of  Payment.  Borrowers  shall  make all
                  payments in respect of any Loan denominated in any currency in
                  the same  currency,  and shall make all payments in respect of
                  Gold Loans in Dollars or, if a Borrower  so elects  and,  with
                  respect to interest,  the U.S.  Administrative  Agent does not
                  require  payment in Dollars,  Gold. If U.S.  Borrower does not
                  deliver  to the  Administrative  Agent at least  two  Business
                  Days' prior  written  notice of its  intention to repay a Gold
                  Loan in Gold, U.S. Borrower shall be deemed to have elected to
                  repay such Loan in  Dollars.  If the  principal  amount of any
                  Gold Loan is to be repaid in Dollars, the corresponding amount
                  of Dollars to be repaid shall equal the Dollar  Equivalent  of
                  the amount of Gold  constituting  such Gold Loan determined as
                  of the second Business Day preceding the repayment date.

                          (a) Currency Payments by U.S.  Borrower.  All currency
                 payments by U.S.  Borrower of principal and interest in respect

                  Office to the U.S. Borrower Account.

                 Canadian  Borrower of principal  and interest in respect of (1)
                 Loans, (2) Letters of Credit, (3) Bankers' Acceptances, and (4)
                 any other fees and  Obligations  hereunder  and under any Notes
                 shall be made in the same  currency  as  incurred,  in same day
                 funds and without defense, setoff or counterclaim,  free of any
                 restriction   or   condition,   and   delivered   to   Canadian
                 Administrative  Agent not later than 12:00 Noon (Toronto  time)
                 on the  date due at  Canadian  Administrative  Agent's  Lending
                 Office.

                          (c) Payments by Australian Borrowers.  All payments by
                 Australian  Borrowers of  principal  and interest in respect of
                 (1) Loans,  (2)  Letters of Credit,  and (3) any other fees and
                 Obligations  hereunder and under any Notes shall be made in the
                 same  currency  as  incurred,  in same day  funds  and  without

                          (d) Gold Payments.  All payments of Gold shall be made
                 by Delivery of such Gold by U.S. Borrower to the Administrative
                 Agent's  account with J.P.  Morgan,  London,  England,  or such
                 other bullion depository as may be designated by the Applicable
                 Administrative  Agent  from  time to time,  before  12:00  Noon
                 (London time) on the day specified for payment.

         Funds  or Gold  received  by the  Applicable  Administrative  Agent  or
         Administrative  Agent after the times  specified above on the due dates
         specified  above shall be deemed to have been paid by  Borrowers on the
         next succeeding Business Day.

                  |(ii)  Application of Payments to Principal and Interest.  All
                  payments in respect of the principal  amount of any Loan shall
                  include  payment of accrued  interest on the principal  amount
                  being  repaid  or  prepaid,  and all  such  payments  shall be

                  |(iii)  Apportionment  of Payments.  Aggregate  principal  and
                  interest  payments shall be apportioned  among all outstanding
                  Loans  to  which   such   payments   relate,   in  each   case
                  proportionately  to each Lending Unit's respective  Australian
                  Lender Pro Rata Share,  Canadian Lender Pro Rata Share or U.S.
                  Lender Pro Rata share, as applicable,  of such Loans.  Subject
                  to the  last  sentence  of  subsection  2.7D,  the  Applicable
                  Administrative Agent or Administrative  Agent, as the case may
                  be, shall promptly  distribute to each Lender,  at its Lending
                  Office or at such other  address as such  Lender may  request,
                  its  proportionate  share of all such payments received by the

                                       53

                  be, pursuant to subsection 2.3.  Notwithstanding the foregoing
                  provisions of this subsection  2.4B(iii),  if, pursuant to the
                  provisions    of    subsection    2.6C,    any    Notice    of
                  Conversion/Continuation is withdrawn as to any Affected Lender
                  or if any Affected  Lender makes U.S.  Base Rate Loans in lieu
                  of its share of any  Eurodollar  Rate  Loans,  the  Applicable
                  Administrative Agent or Administrative  Agent, as the case may
                  be,  shall  give  effect  thereto  in  apportioning   payments
                  received thereafter.

                  |(iv)  Payments on Business  Days.  Whenever any payment to be
                  made hereunder  shall be stated to be due on a day that is not
                  a  Business  Day,  such  payment  shall  be made  on the  next
                  succeeding  Business  Day,  but not later than the  Commitment
                  Termination Date, and such extension of time shall be included
                  in the computation of the payment of interest  hereunder or of
                  the commitment fees hereunder, as the case may be.

                  (v)  Notation  of  Payment.  Each  Lender  agrees  that before
                  disposing of any Note or Grid Gold Acknowledgement held by it,
                  or any part  thereof  (other than by  granting  participations
                  therein),  that  Lender  will make a  notation  thereon of all
                  Loans evidenced by that Note or Grid Gold  Acknowledgement and
                  all principal payments previously made thereon and of the date
                  to which  interest  thereon has been paid;  provided  that the
                  failure to make (or any error in the making of) a notation  of
                  any Loan made  under  such  Note or Grid Gold  Acknowledgement
                  shall not limit,  increase or otherwise affect the obligations
                  of any  Borrower  hereunder  or under  such  Note or Grid Gold
                  Acknowledgement  with  respect to any Loan or any  payments of
                  principal   or   interest   on  such   Note   or   Grid   Gold
                  Acknowledgement.

2.5      Use of Proceeds.

                  A. Loans.  The proceeds of the initial  Loans shall be used by
Borrowers to repay all amounts owing under the Existing Credit  Agreement on the
Effective  Date and repay any amounts owing under the Plutonic  Credit  Facility
and the  proceeds  of the Loans  shall be used by  Borrowers  to provide for the
working capital requirements of Borrowers and their respective Subsidiaries,  to
provide for general  corporate  purposes and to pay fees and expenses related to
the transactions contemplated hereby.

                  B.  Margin  Regulations.  No  portion of the  proceeds  of any
borrowing under this Agreement shall be used by any Borrower,  Company or any of
its Subsidiaries in any manner that might cause the borrowing or the application
of such proceeds to violate  Regulation  T,  Regulation U or Regulation X of the
Board or any other  regulation  of the Board or to violate the Exchange  Act, in
each case as in effect  on the date or dates of such  borrowing  and such use of
proceeds.

                  error, be final,  conclusive and binding upon all parties) the
                  interest  rate that shall apply to such  Eurodollar  Rate Loan
                  for which an interest  rate is then being  determined  for the
                  applicable  Interest  Period and shall  promptly  give  notice
                  thereof (in writing or by  telephone  confirmed in writing) to
                  the applicable Borrower and each applicable Lender.

                  |(ii) Gold Loans. As soon as practicable after 10:00 A.M. (New
                  York  time)  on the  Interest  Rate  Determination  Date  with
                  respect to any Gold Loan, Administrative Agent shall determine
                  (which  determination  shall, absent manifest error, be final,
                  conclusive  and binding upon all  parties)  the interest  rate
                  that shall apply to such Gold Loan for which an interest  rate
                  is then being  determined for the applicable  Interest Period,
                  and  Administrative  Agent shall  promptly give notice thereof
                  (in  writing or by  telephone  confirmed  in  writing) to U.S.
                  Borrower and each applicable Lender.

                  |(iii) Bank Bill Swap Rate Loans. As soon as practicable after
                  11:00  A.M.  (Sydney  time) on any  proposed  Funding  Date or
                  proposed continuation date, as applicable, with respect to any
                  Bank Bill  Swap Rate  Loan,  Australian  Administrative  Agent
                  shall determine (which  determination  shall,  absent manifest
                  error,  be final,  conclusive  and binding on all parties) the
                  interest  rate  that  shall  apply to such Bank Bill Swap Rate
                  Loan for which an interest rate is then being  determined  for
                  the applicable  Interest Period and shall promptly give notice
                  thereof (in writing or by  telephone  confirmed in writing) to
                  Australian Borrowers and each applicable Lender.

                  B.  Inability to Determine  Applicable  Interest  Rate. If the
Applicable Administrative Agent shall have determined (which determination shall
be final and  conclusive  and binding  upon all parties  hereto) on any Interest
Rate  Determination  Date that by reason of  circumstances  affecting the London
interbank market or because no Reference Lender is able to provide its quotation
of a rate, in the case of Eurodollar Rate Loans, or affecting the  international
precious  metals  markets or because  no Gold Rate  Reference  Lender is able to
provide its  quotation of a rate,  in the case of Gold Loans,  adequate and fair
means do not exist for  ascertaining the interest rate applicable to such Loans,
the Applicable  Administrative Agent shall on such date give notice (by telecopy
or by  telephone  confirmed  in  writing) to  Borrowers  and each Lender of such

                                       55


determination,  whereupon (i) no Loans may be made as, or continued or converted
to,  Eurodollar Rate Loans or made or continued as Gold Loans until such time as
the  Applicable  Administrative  Agent  notifies  Borrowers and Lenders that the
circumstances giving rise to such notice no longer exist, and (ii) any Notice of
Borrowing  or  Notice  of  Conversion/Continuation  given by any  Borrower  with
respect to the Loans in respect  of which such  determination  was made shall be
deemed to be rescinded by such Borrower.

                  C.  Illegality or  Impracticability  of Eurodollar Rate Loans,
Bank Bill Swap Rate Loans or Gold  Loans.  If on any date any Lender  shall have
determined (which  determination  shall be final and conclusive and binding upon
all parties hereto but shall be made only after consultation with Administrative
Agent) that the making,  maintaining  or  continuation  of its  Eurodollar  Rate
Loans,  Bank Bill Swap Rate  Loans or Gold  Loans,  as the case may be,  (i) has
become  unlawful as a result of compliance by such Lender with any law,  treaty,
governmental  rule,  regulation,  guideline or order (or would conflict with any
such treaty,  governmental rule,  regulation,  guideline or order not having the
force of law even though the failure to comply  therewith would not be unlawful)
or (ii) has become impracticable,  or would cause such Lender material hardship,
as a result of  contingencies  occurring  after the date of this Agreement which
materially  and  adversely  affect the London  interbank  market (in the case of
Eurodollar Rate Loans),  the international  precious metals markets (in the case
of Gold Loans), the bills of exchange market (in the case of Bank Bill Swap Rate
Loans) or the position of such Lender in any such market,  then, and in any such
event,  such Lender shall be an "Affected  Lender" and it shall on that day give
notice (by  telecopy or by  telephone  confirmed  in writing) to  Borrowers  and
Administrative  Agent of such determination  (which notice  Administrative Agent
shall promptly transmit to each other Lender). Thereafter, (a) the obligation of
the Affected  Lender to make Loans as, or to convert Loans to or continue  Loans
as,  Eurodollar Rate Loans, Bank Bill Swap Rate Loans or Gold Loans, as the case
may be, shall be suspended  until such notice shall be withdrawn by the Affected
Lender, (b) to the extent such determination by the Affected Lender relates to a
Eurodollar  Rate  Loan,  a Bank Bill  Swap  Rate Loan or a Gold Loan then  being
requested  by a  Borrower  pursuant  to a Notice  of  Borrowing  or a Notice  of
Conversion/Continuation, the Affected Lender shall make such Loan as (or convert
such Loan to, as the case may be) (i) a U.S.  Base Rate Loan if the  Borrower is
the U.S.  Borrower,  (ii) a U.S.  Base Rate  (Canada)  Loan if the  Borrower  is
Canadian Borrower,  and (iii) if one of the Borrowers is an Australian Borrower,
at the  election of such  Australian  Borrower  made within one  Business Day of
receipt of notice from the  Affected  Lender,  a Bank Bill Swap Rate Loan with a
period of one month (if that option is available)  or a Loan in Dollars  bearing
interest at the  Australian  Administrative  Agent's cost of funds as reasonably
determined  by  Administrative  Agent,  plus the  Applicable  Margin  (such Loan
bearing  interest at the Bank Bill Swap Rate if no timely election is made), (c)
the Affected  Lender's  obligation to maintain its  outstanding  Eurodollar Rate
Loans,  Bank  Bill  Swap  Rate  Loans  or Gold  Loans,  as the  case may be (the
"Affected Loans"), shall be terminated at the earlier to occur of the expiration
of the Interest  Period then in effect with respect to the Affected  Loans or if
earlier when  required by law, and (d) the  Affected  Loans shall  automatically
convert  on the date of such  termination  to (i) a U.S.  Base  Rate Loan if the
Borrower  is the U.S.  Borrower,  (ii) a U.S.  Base  Rate  (Canada)  Loan if the
Borrower  is  Canadian  Borrower,  and  (iii)  if  one of  the  Borrowers  is an
Australian Borrower, at the election of such Australian Borrower made within one
Business  Day of receipt of notice from the  Affected  Lender,  a Bank Bill Swap


                                       56


Rate Loan with a period of one month (if that option is  available) or a Loan in
Dollars bearing  interest at the Alternate Base Rate (such Loan bearing interest
at the Alternate Base Rate if no timely election is made).  Notwithstanding  the
foregoing,  to the extent a  determination  by an Affected  Lender as  described
above  relates to a  Eurodollar  Rate Loan, a Bank Bill Swap Rate Loan or a Gold
Loan then being requested by any Borrower pursuant to a Notice of Borrowing or a
Notice of Conversion/Continuation,  such Borrower shall have the option, subject
to the  provisions  of  subsection  2.6D, to rescind such Notice of Borrowing or
Notice  of  Conversion/Continuation  as to all  Lenders  by  giving  notice  (by
telecopy or by telephone  confirmed in writing) to Administrative  Agent and the
Applicable  Administrative  Agent of such  rescission  on the date on which  the
Affected  Lender gives  notice of its  determination  as described  above (which
notice of rescission the Applicable Administrative Agent shall promptly transmit
to  each  other  applicable  Lender).  Except  as  provided  in the  immediately
preceding sentence,  nothing in this subsection 2.6C shall affect the obligation
of any Lender other than an Affected  Lender to make or maintain Loans as, or to
convert or continue Loans as,  Eurodollar Rate Loans,  Bank Bill Swap Rate Loans
or Gold Loans in accordance  with the terms of this  Agreement.  Borrowers shall
have the right  upon 20 days'  notice to each  Lender  and upon  consent  by the
Applicable  Administrative  Agents,  which  consent  shall  not be  unreasonably
withheld, and so long as no Potential Event of Default or Event of Default shall
have occurred,  to substitute Eligible Assignees for the Affected Lender and any
Lender that belongs to the Affected  Lender's  Lending Unit hereunder;  provided
such  substitute  Lenders,  taken  together,  will constitute a Lending Unit. If
Borrowers select such substituted  Lenders,  the Affected Lender,  and any other
Lender  belonging  to the Affected  Lender's  Lending  Unit,  shall assign their
Notes,  Grid Gold  Acknowledgements  and  rights  under this  Agreement  to such
substitute  Lenders in accordance with subsection 10.1B (but without the payment
of any recordation fee) for the amount due on prepayment  pursuant to subsection
2.4(A)(i) together with any amounts that may be due pursuant to subsection 2.6D.

                  D. Compensation For Breakage or  Non-Commencement  of Interest
Periods. Any Borrower having borrowed, or having delivered a Notice of Borrowing
or a  Notice  of  Conversion/Continuation  to  request  to  borrow,  convert  or
continue,  any Eurodollar Rate Loan, Bank Bill Swap Rate Loan or Gold Loan shall
compensate each Lender, upon written request by that Lender (which request shall
set forth the basis for  requesting  such amounts),  for all reasonable  losses,
expenses and liabilities  (including,  without limitation,  any interest paid by
that Lender to lenders of funds (or Gold in the case of Gold Loans)  borrowed by
it to make or carry its Eurodollar Rate Loans, Bank Bill Swap Rate Loans or Gold
Loans, as the case may be) (including loss of anticipated  profits) sustained by
that Lender in connection  with the liquidation or  re-employment  of such funds
(or Gold),  which that Lender may sustain:  (i) if for any reason  (other than a
default by that Lender) the  borrowing of the  Eurodollar  Rate Loan,  Bank Bill
Swap Rate Loan or Gold Loan  requested by such Borrower does not occur on a date
specified  therefor  in such Notice of  Borrowing  or a  telephonic  request for
borrowing,  or the conversion to or  continuation  requested by such Borrower of
any Eurodollar  Rate Loan,  Bank Bill Swap Rate Loan or Gold Loan does not occur
on a  date  specified  therefor  in a  Notice  of  Conversion/Continuation  or a
telephonic  request for  conversion or  continuation,  (ii) if any prepayment or
conversion of any Eurodollar Rate Loans, Bank Bill Swap Rate Loans or Gold Loans
made to such  Borrower by such Lender  occurs on a date that is not the last day
of an Interest  Period  applicable to that Loan,  


                                       57


(iii) if any prepayment of any such Eurodollar  Rate Loans,  Bank Bill Swap Rate
Loans or Gold Loans is not made on any date  specified in a notice of prepayment
given by such  Borrower,  or (iv) as a consequence  of any other default by such
Borrower to repay its Eurodollar  Rate Loans,  Bank Bill Swap Rate Loans or Gold
Loans when required by the terms of this Agreement.

                  E. Booking of Eurodollar Rate Loans. Subject to the provisions
of subsection 10.8, any Lender may make, carry or transfer Eurodollar Rate Loans
at,  to, or for the  account  of any of its  branch  offices or the office of an
Affiliate of that Lender.

                  F.  Assumptions  Concerning  Funding of Eurodollar Rate Loans.
Calculation  of all amounts  payable to a Lender under this  subsection  2.6 and
under  subsection  10.7A shall be made as though that Lender had actually funded
each of its relevant  Eurodollar Rate Loans through the purchase of a Eurodollar
deposit  bearing  interest at the rate  obtained  pursuant to the  definition of
Eurodollar  Rate in an amount equal to the amount of such  Eurodollar  Rate Loan
and having a maturity comparable to the relevant Interest Period and through the
transfer of such Eurodollar  deposit from an offshore office of that Lender to a
domestic  office of that  Lender in the  United  States  of  America,  Canada or
Australia;  provided,  however, that each Lender may fund each of its Eurodollar
Rate  Loans in any  manner it sees fit and the  foregoing  assumptions  shall be
utilized  only for the  purposes  of  calculating  amounts  payable  under  this
subsection 2.6 and under subsection 10.7A.

                  G. Eurodollar  Rate Loans,  Bank Bill Swap Rate Loans and Gold
Loans After Default. Except as provided in subsection 2.2D, after the occurrence
of and during the  continuation  of a Potential  Event of Default or an Event of
Default, (i) Borrowers may not elect to have a Loan be made or maintained as, or
converted  to, a  Eurodollar  Rate  Loan,  Bank Bill Swap Rate Loan or Gold Loan
after the  expiration  of any  Interest  Period then in effect for that Loan and
(ii) subject to the  provisions of subsection  2.6D,  any Notice of Borrowing or
Notice  of  Conversion/Continuation  given  by  a  Borrower  with  respect  to a
requested borrowing or  conversion/continuation  that has not yet occurred shall
be deemed to be rescinded by such Borrower.

2.7      Letters of Credit

                  A. Letters of Credit.  Subject to the terms and  conditions of
this  Agreement  and in reliance  upon the  representations  and  warranties  of
Company and Borrowers set forth herein, each Borrower may request, in accordance
with the  provisions of this  subsection  2.7A,  that on and after the Effective
Date the  applicable  Issuing  Lender issue Letters of Credit for the account of
such Borrower  denominated in (i) Dollars (in the case of U.S.  Borrower),  (ii)
Canadian  Dollars  or  Dollars  (in the  case of  Canadian  Borrower)  or  (iii)
Australian  Dollars  or  Dollars  (in the case of  Australian  Borrowers).  Such
Letters of Credit  shall be issued  solely for the  purpose  of  supporting  the
obligations of Borrowers and their respective Subsidiaries. Issuances of Letters
of Credit shall be subject to the following limitations:

                  (i) No Borrower  shall  request any Letter of Credit if, after
                  giving effect to such issuance,  (a) the Total  Utilization of
                  Overall Commitments would exceed the Overall Commitments,  (b)
                  the  Canadian  Commitment  Usage  would  exceed  the  


                                       58


                  Canadian  Allocation,  (c) the Australian  Commitment  Usage
                  would  exceed  the  Australian  Allocation,   (d)  the  U.S.
                  Commitment Usage would exceed the U.S.  Allocation,  (e) the
                  Letter of Credit Usage would exceed $125,000,000, or (f) any
                  Lending  Unit's Pro Rata Share of the Total  Utilization  of
                  Overall  Commitments  after giving  effect to such  issuance
                  would exceed such Lending Unit's  Commitment then in effect;
                  and

                  (ii) In no event  shall any  Issuing  Lender  issue,  reissue,
                  amend or permit  the  extension  of:  (x) any Letter of Credit
                  having an expiration  date  (including  after giving effect to
                  any extension)  later than the Commitment  Termination Date in
                  effect  at the  time of  issuance,  reissuance,  amendment  or
                  extension (automatic or otherwise) thereof; (y) subject to the
                  foregoing   clause  (x),  any  Letter  of  Credit   having  an
                  expiration date more than one year after its date of issuance;
                  provided that subject to the foregoing clause (x), this clause
                  (y) shall not prevent such Issuing Lender from agreeing that a
                  Letter of Credit will automatically be extended annually for a
                  period not to exceed one year if such Issuing  Lender does not
                  cancel such extension.

                  It shall  be a  condition  precedent  to the  issuance  of any
Letter of Credit in accordance  with the provisions of this  subsection 2.7 that
each condition set forth in subsection 3.3 shall have been satisfied.

                  Immediately  upon the issuance of each Letter of Credit,  each
Canadian  Lender,  in the case of any Letter of Credit issued for the account of
Canadian  Borrower,  each Australian Lender, in the case of any Letter of Credit
issued for the account of Australian Borrowers, or each U.S. Lender, in the case
of any Letter of Credit issued for the account of U.S. Borrower, shall be deemed
to, and hereby agrees to, have irrevocably purchased from the applicable Issuing
Lender an undivided and  continuing  participation  in such Letter of Credit and
drawings  thereunder in an amount equal to such Lender's  Australian  Lender Pro
Rata Share,  Canadian  Lender Pro Rata Share or U.S.  Lender Pro Rata Share,  as
applicable,  of the maximum amount which is or at any time may become  available
to be drawn thereunder.

                  The  applicable  Issuing  Lender may upon the occurrence of an
Event of Default and the acceleration of the maturity of the Loans,  provide for
the deposit of funds in an account to secure payment to the  beneficiary and any
funds so deposited  shall be paid to the  beneficiary of the Letter of Credit if
conditions to such payment are satisfied or returned to the  applicable  Issuing
Lender for  distribution  to Lenders  (or,  if all  Obligations  shall have been
indefeasibly  paid in full,  to the  applicable  Borrower)  if no payment to the
beneficiary  has been  made and 30 days  after  the  final  date  available  for
drawings under the Letter of Credit has passed. Each payment or deposit of funds
by the applicable  Issuing Lender as provided in this paragraph shall be treated
for all purposes of this  Agreement as a drawing duly honored by the  applicable
Issuing Lender under the related Letter of Credit.

                  B. Notice of Issuance.  Whenever Canadian Borrower desires the
issuance  of a Letter of Credit,  it shall  deliver to  Canadian  Administrative
Agent and  Administrative  Agent a 

                                       60


Notice of Issuance of Letter of Credit in the form of Exhibit XI hereto no later
than 1:00 P.M. (Toronto time) at least five Business Days or such shorter period
as may be agreed to by the applicable Issuing Lender in any particular instance,
in advance of the proposed  date of issuance.  Whenever an  Australian  Borrower
desires  the  issuance  of a Letter of Credit,  it shall  deliver to  Australian
Administrative  Agent and Administrative Agent a Notice of Issuance of Letter of
Credit in the form of Exhibit XI hereto no later than 1:00 P.M. (Sydney time) at
least  five  Business  Days or such  shorter  period  as may be agreed to by the
applicable Issuing Lender in any particular instance, in advance of the proposed
date of issuance.  Whenever  U.S.  Borrower  desires the issuance of a Letter of
Credit, it shall deliver to Administrative  Agent a Notice of Issuance of Letter
of Credit in the form of  Exhibit  XI hereto no later  than 1:00 P.M.  (New York
time) at least five Business Days or such shorter  period as may be agreed to by
the  applicable  Issuing Lender in any  particular  instance,  in advance of the
proposed  date of  issuance.  Each Notice of Issuance of Letter of Credit  shall
specify (i) the Borrower,  (ii) the proposed date of issuance  (which shall be a
Business  Day),  (iii)  the  face  amount  of the  Letter  of  Credit,  (iv) the
expiration  date of the  Letter  of  Credit,  (v) the  name and  address  of the
beneficiary,  (vi) a summary of the purpose and the verbatim text of such Letter
of Credit,  and (vii) a precise  description  of the  documents and the proposed
text of any certificate to be presented by the  beneficiary  which, if presented
by the beneficiary  prior to the expiration date of the Letter of Credit,  would
require  the  applicable  Issuing  Lender to make  payment  under the  Letter of
Credit;  provided that the applicable  Issuing  Lender,  in its sole  reasonable
judgment,  may  require  changes in any such  documents  and  certificates;  and
provided  further  that no Letter  of Credit  shall  require  payment  against a
conforming  draft to be made thereunder on the same Business Day that such draft
is  presented  if such  presentation  is made after  11:00 A.M.  (New York time,
Toronto time or Sydney time, as applicable,) on such Business Day. Promptly upon
the issuance of a Letter of Credit,  the applicable  Issuing Lender shall notify
the  applicable  Lenders of the  applicable  Borrower of such  issuance  and the
details thereof.  In determining  whether to pay under any Letter of Credit, the
applicable  Issuing  Lender  shall be  responsible  only to  determine  that the
documents and certificates  required to be delivered under that Letter of Credit
have been delivered and that they comply on their face with the  requirements of
that Letter of Credit.

                  C. Payment of Amounts  Drawn Under  Letters of Credit.  In the
event of any drawing under any Letter of Credit by the beneficiary  thereof, the
applicable  Issuing Lender shall promptly  notify the Borrower for whose account
such  Letter of  Credit  was  issued,  and such  Borrower  shall  reimburse  the
applicable  Issuing  Lender on the date on which such  drawing is honored in the
same  currency as the drawing in an amount in same day funds equal to the amount
of such drawing;  provided  that,  anything  contained in this  Agreement to the
contrary  notwithstanding,  (i) unless such  Borrower  shall have  notified  the
Applicable  Administrative Agent prior to 11:00 A.M. (New York Toronto or Sydney
time, as applicable,) on the Business Day immediately  prior to the date of such
drawing that such Borrower  intends to reimburse the  applicable  Issuing Lender
for the amount of such drawing with funds other than the proceeds of Loans, such
Borrower shall be deemed to have (1) in the case of Canadian  Borrower,  given a
Notice of Borrowing to Canadian  Administrative  Agent and Administrative  Agent
requesting  Canadian  Lenders to make  Canadian  Loans (which shall be U.S. Base
Rate (Canada) Loans or Canadian Base Rate Loans denominated in the same currency
as the drawing) to the extent of the unused  Canadian  Allocation on the date on
which such  drawing is honored in an amount  equal to

                                       60



the amount of such drawing or, (2) in the case of Australian Borrowers,  given a
Notice of Borrowing to Australian  Administrative Agent and Administrative Agent
requesting Australian Lenders to make Australian Loans (which shall be Bank Bill
Swap Rate Loans or Eurodollar  Rate Loans with a one month  interest  period) to
the extent of the unused Australian Allocation on the date on which such drawing
is honored in an amount  equal to the amount of such drawing and (3) in the case
of U.S. Borrower, given a Notice of Borrowing to Administrative Agent requesting
U.S.  Lenders to make U.S.  Loans (which  shall be U.S.  Base Rate Loans) to the
extent of the  unused  U.S.  Allocation  on the date on which  such  drawing  is
honored in an amount  equal to the amount of such  drawing,  and (ii) subject to
satisfaction  or waiver of the  conditions  specified in  subsection  3.2,  such
Lenders  shall,  on the date of such  drawing,  make such Loans in the aggregate
amount of such drawing,  the proceeds of which shall be applied  directly by the
Applicable  Administrative  Agent to reimburse the applicable Issuing Lender for
the amount of such drawing;  and provided further that, if Loans are required to
be made and for any reason  proceeds of Loans are not received by the applicable
Issuing  Lender on such date in an amount  equal to the amount of such  drawing,
the applicable  Borrower shall reimburse the applicable  Issuing Lender,  on the
Business Day  immediately  following the date of such  drawing,  in an amount in
same day funds (and in the same currency as the  unreimbursed  drawing) equal to
the excess of the amount of such drawing over the amount of such Loans which are
so  received,  plus  accrued  interest  on such  amount at the rate set forth in
subsection 2.7E(ii).

                  D. Payment by Lenders  with  Respect to Letters of Credit.  If
any Borrower shall fail to reimburse the  applicable  Issuing Lender as provided
in  subsection  2.7C in an amount equal to the amount of any drawing  honored by
the applicable  Issuing Lender under a Letter of Credit issued by the applicable
Issuing Lender for the account of such Borrower,  the applicable  Issuing Lender
shall  promptly  notify the Applicable  Administrative  Agent and the Applicable
Administrative  Agent  shall  promptly  notify  Administrative  Agent  and  each
applicable  Lender of the unreimbursed  amount of such drawing,  the currency in
which such drawing was funded,  and of such  Lender's  respective  participation
therein, which participation shall be equal to such Lender's Canadian Lender Pro
Rata Share,  Australian  Lender Pro Rata Share or U.S. Lender Pro Rata Share, as
applicable,  of the unreimbursed amount of such drawing.  Each applicable Lender
shall make  available to the  applicable  Issuing  Lender an amount equal to its
respective  participation  in same day  funds  and in the same  currency  as the
drawing,  at the  office of the  applicable  Issuing  Lender  specified  in such
notice,  not  later  than 1:00 P.M.  (New  York,  Toronto  or  Sydney  time,  as
applicable)  on the day such  notice is given to such  Lender by the  Applicable
Administrative  Agent.  If any applicable  Lender fails to make available to the
applicable  Issuing  Lender the amount of such  Lender's  participation  in such
Letter of Credit as provided in this  subsection  2.7D, the  applicable  Issuing
Lender  shall be  entitled  to recover  such  amount on demand  from such Lender
together  with  interest at the  customary  rate set by the  applicable  Issuing
Lender for the  correction  of errors  among banks for three  Business  Days and
thereafter at the Canadian Base Rate, in the case of Canadian  Dollar  drawings,
the  Bank  Bill  Swap  Rate  for a one  month  Interest  Period  in the  case of
Australian  Dollar  drawings or the  Alternate  Base Rate, in the case of Dollar
drawings by U.S. Borrower and Australian Borrowers,  and U.S. Base Rate (Canada)
in the case of Dollar drawings by Canadian Borrower.  Nothing in this subsection
2.7 shall be deemed to  prejudice  the right of any Lender to  recover  from the
applicable  Issuing  Lender any  amounts  made  available  by such Lender to the
applicable  Issuing Lender  pursuant to this 
\

                                       61


subsection  2.7D if the  payment  with  respect  to a Letter  of  Credit  by the
applicable  Issuing  Lender in respect of which  payment was made by such Lender
constituted gross negligence or willful misconduct on the part of the applicable
Issuing Lender, as finally determined by a court of competent jurisdiction.  The
applicable  Issuing  Lender shall  distribute to the  Applicable  Administrative
Agent for  distribution  to each other Lender which has paid all amounts payable
by it under this  subsection 2.7D with respect to any Letter of Credit issued by
the  applicable  Issuing  Lender such other  Lender's  Canadian  Lender Pro Rata
Share,  Australian  Lender Pro Rata  Share or U.S.  Lender  Pro Rata  Share,  as
applicable,  of all payments received by the applicable  Issuing Lender from any
Borrower in reimbursement  of drawings honored by the applicable  Issuing Lender
under such Letter of Credit when such  payments  are  received.  Notwithstanding
anything to the contrary  herein,  each Lender that has paid all amounts payable
by it under this subsection 2.7D shall have a direct right to  reimbursement  of
such  amounts  from the  applicable  Borrower,  subject  to the  procedures  for
reimbursing Lenders set forth in this subsection 2.7.

                  E.   Compensation.   Each  Borrower  agrees  to  pay,  without
duplication, the following amounts to the applicable Issuing Lender with respect
to each Letter of Credit issued by the applicable Issuing Lender for the account
of such Borrower:

                  (i) with respect to each Letter of Credit,  a letter of credit
                  fee  payable  to  the  applicable   Issuing  Lender  equal  to
                  applicable  Letter of Credit  Fee  Percentage  of the  maximum
                  amount  available  from  time to time to be drawn  under  such
                  Letter of Credit,  calculated  on the basis of a 360-day year,
                  in the case of  Letters of Credit  issued  for the  account of
                  U.S.  Borrower or  Australian  Borrowers,  or a 365 or 366-day
                  year (as  applicable)  in the case of Letters of Credit issued
                  for the account of Canadian  Borrower,  and, in each case, the
                  actual number of days elapsed and payable quarterly in arrears
                  on March 31,  June 30,  September  30 and  December 31 of each
                  year in immediately  available  funds and in the same currency
                  as the Letter of Credit;

                  (ii) with respect to drawings made under any Letter of Credit,
                  interest, payable on demand in immediately available funds and
                  in the same currency as the drawing, on the amount paid by the
                  applicable Issuing Lender in respect of each such drawing from
                  the date of the  drawing  through  the  date  such  amount  is
                  reimbursed  by  the  applicable  Borrower  (but  only  if  not
                  reimbursed when due) at a rate which is 2% per annum in excess
                  of the rate of interest otherwise payable under this Agreement
                  for  Canadian  Base Rate  Loans,  in the case of any  Canadian
                  Dollar  drawings,  the Bank  Bill  Swap  Rate for a one  month
                  Interest Period,  in the case of Australian Dollar drawings or
                  U.S.  Base Rate Loans,  in the case of any Dollar  drawings by
                  U.S.  Borrower and  Australian  Borrowers,  or U.S.  Base Rate
                  (Canada) Loans in the case of any Dollar  drawings by Canadian
                  Borrower; and

                  (iii) with respect to the  issuance,  amendment or transfer of
                  each  Letter  of  Credit  and each  drawing  made  thereunder,
                  documentary  and  processing  charges in  accordance  with the
                  applicable Issuing Lender's standard schedule for such charges
                  in effect at the time of such issuance, amendment, transfer or
                  drawing, as 


                                       62


                  the case may be, or as otherwise agreed by Issuing Lender,
                  Company and Borrowers.

                  Promptly upon receipt by the applicable  Issuing Lender of any
amount  described  in  subdivision  (i) or  (ii) of this  subsection  2.7E,  the
applicable  Issuing  Lender shall  distribute to the  Applicable  Administrative
Agent  for  distribution  to each  Canadian  Lender,  Australian  Lender or U.S.
Lender,  as the case may be,  its  Canadian  Lender Pro Rata  Share,  Australian
Lender Pro Rata Share or U.S.  Lender Pro Rata  Share,  as  applicable,  of such
amount.

                  F.  Obligations  Absolute.  The obligation of each Borrower to
reimburse  any  Issuing  Lender for  drawings  made under the  Letters of Credit
issued  for  such  Borrower's  account  and the  obligations  of  Lenders  under
subsection  2.7D  shall  be  unconditional  and  irrevocable  and  shall be paid
strictly in accordance with the terms of this Agreement under all circumstances,
including, without limitation, the following circumstances:

                  (i)      any lack of validity or enforceability of any Letter 
                  of Credit;

                  (ii) the  existence  of any claim,  set-off,  defense or other
                  right the  applicable  Borrower may have at any time against a
                  beneficiary  or any transferee of any Letter of Credit (or any
                  persons  or  entities  for  whom any  such  transferee  may be
                  acting),  any  Issuing  Lender,  any Agent,  any Lender or any
                  other Person,  whether in connection with this Agreement,  the
                  transactions  contemplated herein or any unrelated transaction
                  (including any underlying transaction between such Borrower or
                  any of its  Subsidiaries  and the  beneficiary  for  which the
                  Letter of Credit was procured);

                  (iii)  any  draft,  demand,   certificate  or  other  document
                  presented  under any  Letter of Credit  proving  to be forged,
                  fraudulent or invalid in any respect or any statement  therein
                  being untrue or inaccurate in any respect;

                  (iv) payment by any Issuing Lender against a demand,  draft or
                  certificate  or other  document which does not comply with the
                  terms of such  Letter of Credit  unless  such  Issuing  Lender
                  failed to exercise  reasonable  care in  ascertaining  whether
                  such  document  appeared on its face to comply in all material
                  respects with such terms;

                  (v)      any other circumstance or happening whatsoever, which
                  is similar to any of the foregoing; or

                  (vi) the fact that an Event of Default or a Potential Event of
                  Default shall have occurred and be continuing.

                  G.  Additional  Payments.  If by reason  of (a) any  change in
applicable law, regulation, rule, decree or regulatory requirement or any change
in the interpretation or application by any judicial or regulatory  authority of
any law, regulation, rule, decree or regulatory requirement or (b) compliance by
any Issuing  Lender or any Lender  with any  direction,

                                       63


request  or  requirement  (whether  or not  having  the  force  of  law)  of any
governmental or monetary authority including, without limitation, Regulation D:

                  (i) any reserve, deposit or similar requirement is or shall be
                  applicable,  imposed or  modified in respect of any Letters of
                  Credit issued by any Issuing Lender or participations  therein
                  purchased by any Lender; or

                  (ii)  there  shall be  imposed  on any  Issuing  Lender or any
                  Lender any other condition  regarding this subsection 2.7, any
                  Letter of Credit or any participation therein;


and the result of the foregoing is to directly or  indirectly  increase the cost
to any Issuing Lender or any Lender of issuing, making or maintaining any Letter
of Credit or of purchasing  or  maintaining  any  participation  therein,  or to
reduce the amount  receivable  in respect  thereof by any Issuing  Lender or any
Lender,  then and in any such case such Issuing Lender or such Lender may notify
the  Borrower  for whose  account  such  Letter of Credit  was  issued  and such
Borrower  shall pay within ten days of  receipt of notice  such  amounts as such
Issuing Lender or such Lender may specify pursuant to the certificate  described
below to be necessary to compensate  such Issuing Lender or such Lender for such
additional cost or reduced  receipt,  together with interest on such amount from
the date of such  demand  until  payment in full  thereof at a rate equal at all
times to the Alternate  Base Rate per annum.  The  determination  by any Issuing
Lender or any  Lender,  as the case may be, of any amount due  pursuant  to this
subsection  2.7G as set forth in a  certificate  setting  forth the  calculation
thereof in reasonable detail,  shall, in the absence of manifest error, be final
and conclusive and binding on all of the parties hereto.

                  H.  Indemnification;  Nature of Issuing  Lender's  Duties.  In
addition to amounts  payable as elsewhere  provided in this subsection 2.7, each
Borrower hereby agrees to protect,  indemnify,  pay and save each Issuing Lender
harmless  from and against any and all claims,  demands,  liabilities,  damages,
losses, costs, charges and expenses (including reasonable attorneys' fees) which
such  Issuing  Lender  may incur or be subject  to as a  consequence,  direct or
indirect,  of (i) the  issuance  of any Letter of Credit for the account of such
Borrower, or (ii) the failure of any Issuing Lender to honor a drawing under any
such Letter of Credit as a result of any act or  omission,  whether  rightful or
wrongful,  of  any  present  or  future  de  jure  or  de  facto  government  or
governmental  authority  (all such acts or omissions  herein called  "Government
Acts").

                  As  between  any  Issuing  Lender and any  Borrower  for whose
account any Issuing  Lender issues any Letter of Credit,  such Borrower  assumes
all risks of the acts and omissions of or misuse of any such Letter of Credit by
the  beneficiary  of any  such  Letter  of  Credit.  In  furtherance  and not in
limitation of the foregoing, no Issuing Lender shall be responsible: (i) for the
form,  validity,  sufficiency,  accuracy,  genuineness  or legal  effect  of any
document  submitted  by any party in  connection  with the  application  for and
issuance of such Letters of Credit, even if it should in fact prove to be in any
or all respects invalid,  insufficient,  inaccurate,  fraudulent or forged; (ii)
for the validity or sufficiency of any instrument  transferring  or assigning or
purporting  to  transfer  or assign  any such  Letter of Credit or the rights or
benefits thereunder or proceeds 

                                       64


thereof,  in whole or in part,  which may prove to be invalid or ineffective for
any reason; (iii) for failure of the beneficiary of any such Letter of Credit to
comply fully with the  conditions  required in order to draw upon such Letter of
Credit; (iv) for errors,  omissions,  interruptions or delays in transmission or
delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether
or not they be in cipher;  (v) for errors in  interpretation of technical terms;
(vi) for any loss or delay in the  transmission  or  otherwise  of any  document
required  in order to make a drawing  under any such  Letter of Credit or of the
proceeds  thereof;  (vii) for the  misapplication by the beneficiary of any such
Letter of Credit of the proceeds of any drawing under such Letter of Credit; and
(viii) for any  consequences  arising  from  causes  beyond  the  control of any
Issuing Lender, including,  without limitation, any Government Acts. None of the
above shall  affect,  impair,  or prevent  the  vesting of any Issuing  Lender's
rights or powers hereunder.

                  In  furtherance  and  extension  and not in  limitation of the
specific  provisions  hereinabove set forth,  any action taken or omitted by any
Issuing Lender under or in connection with the Letters of Credit issued by it or
the related  certificates,  if taken or omitted in good faith and without  gross
negligence or willful  misconduct as finally  determined by a court of competent
jurisdiction, shall not put such Issuing Lender under any resulting liability to
any Borrower or Company.

                  Notwithstanding  anything to the  contrary  contained  in this
subsection  2.7, no Borrower  shall have any obligation to indemnify any Issuing
Lender in respect of any liability  incurred by such Issuing  Lender arising out
of the gross negligence or willful misconduct of such Issuing Lender, as finally
determined by a court of competent jurisdiction, or out of the wrongful dishonor
by such  Issuing  Lender of proper  demand for payment made under the Letters of
Credit issued by it; provided that payment  against a draft or demand  presented
after the expiration  date of any Letter of Credit shall be deemed to constitute
gross negligence.

                  I.  Computation  of  Interest.  Interest  payable  pursuant to
subsection  2.7 shall be computed on the basis of a 360-day  year and the actual
number of days elapsed in the period  during which it accrues.  For the purposes
of this subsection 2.7I,  whenever interest is calculated on the basis of a year
of 360 days,  each rate of  interest  determined  pursuant  to such  calculation
expressed  as an annual rate for the  purposes of the  Interest  Act (Canada) is
equivalent to such rate as so determined multiplied by the actual number of days
in the calendar year in which the same is to be ascertained and divided by 360.

2.8      Bankers' Acceptances.

                  A.  Bankers'  Acceptance  Commitment.  Canadian  Borrower  may
request  pursuant to this  subsection  2.8,  from time to time during the period
from the Effective Date to but excluding the Commitment  Termination  Date, that
each  Canadian  Lender  create  Bankers'  Acceptances  by accepting  Drafts from
Canadian  Borrower in an aggregate  amount not exceeding such Canadian  Lender's
Canadian  Lender Pro Rata Share of the  aggregate  Face  Amount of the  Bankers'
Acceptances to be created on any Drawing Date;  provided that Canadian  Borrower
shall not request the  creation of any  Bankers'  Acceptance  if,  after  giving
effect thereto,  (a) the Total  Utilization of Overall  Commitments would exceed
the Overall  Commitments  then in effect,  or 

                                       65


(b) the Canadian  Commitment Usage would exceed the Canadian  Allocation then in
effect,  and no Canadian Lender shall have any obligation to create any Bankers'
Acceptance if, after giving effect thereto, (a) the Total Utilization of Overall
Commitments of its Lending Unit would exceed such Lending Unit's Commitment,  or
(b) its Canadian  Commitment  Usage would exceed its Canadian  Commitment or its
Canadian Lender Pro Rata Share of the Canadian Allocation.  Each Canadian Lender
shall also  purchase  Bankers'  Acceptances  created by it as more  particularly
specified in this subsection 2.8.

                  The aggregate  Face Amount of the Bankers'  Acceptances  to be
created on any Drawing Date shall be not less than Cdn.  $5,000,000 and shall be
in integral  multiples of Cdn.$1,000,000 in excess thereof.  If apportionment of
Bankers'  Acceptances  among the  Canadian  Lenders  cannot be made on a ratable
basis in even multiples of  Cdn.$100,000,  Canadian  Administrative  Agent shall
round  the  allocations  among  Canadian  Lenders  up or  down  to  the  nearest
Cdn.$100,000.

         B.       Drawing Notice.

                  Bankers'  Acceptances  shall be created on two Business  Days'
prior written notice given not later than 11:00 A.M. (Toronto time), by Canadian
Borrower to Canadian Administrative Agent, which shall give each Canadian Lender
prompt  notice  thereof and of such  Canadian  Lender's  ratable  portion of the
aggregate  Face  Amount of the Drafts to be  accepted  (and  purchased)  by such
Canadian Lender. Each such notice (a "Drawing Notice") shall be in substantially
the form of Exhibit III-B annexed hereto or by telephone  confirmed  promptly in
writing,  containing  the same  information  as would be  contained in a Drawing
Notice,  and shall specify therein (i) the Drawing Date; (ii) the aggregate Face
Amount of Drafts to be accepted (and purchased); and (iii) the maturity date for
such Drafts (it being agreed and  understood  that Canadian  Borrower  shall not
request a maturity date for Drafts which would be  subsequent to the  Commitment
Termination Date).

                  Neither Canadian  Administrative Agent nor any Canadian Lender
shall incur any liability to Company or any Borrower in acting on any telephonic
notice  referred to above that  Canadian  Administrative  Agent or such Canadian
Lender believes in good faith to have been given by a duly authorized officer or
other  person  authorized  to  borrow  on behalf  of  Canadian  Borrower  or for
otherwise  acting in good faith under this subsection 2.8, and upon the creation
and purchase of Bankers'  Acceptances  pursuant to any such  telephonic  notice,
Canadian Borrower shall be liable with respect thereto as provided herein.

                  Each  Drawing  Notice  shall be  irrevocable  and  binding  on
Canadian  Borrower.  Canadian  Borrower  shall  indemnify  each Canadian  Lender
against any loss or expense  incurred by such Canadian Lender as a result of any
failure by Canadian  Borrower to fulfill or honor before the applicable  Drawing
Date the applicable  conditions  set forth in this  subsection 2.8 or subsection
3.4 if as a result of such failure,  the requested Bankers'  Acceptances are not
created and/or purchased on such Drawing Date.

                                       66


         C.       Form of Bankers' Acceptances.

                  Each Draft  presented  by  Canadian  Borrower  shall (i) be an
integral multiple of Cdn.$100,000;  (ii) be dated the date of acceptance thereof
by the  applicable  Canadian  Lender;  (iii)  mature and be payable by  Canadian
Borrower  on a Business  Day which  occurs 30, 60, 90 or, if  available  to each
Canadian Lender,  180 days after the date thereof;  (iv) be substantially in the
form of Exhibit III-A annexed hereto; and (iv) be otherwise  consistent with the
provisions of this Agreement relating to the amounts and maturity dates thereof.
The acceptance endorsed by a Canadian Lender on any Draft shall be substantially
in the form of the endorsement set forth in Exhibit III-A annexed hereto or such
other form as may be agreed by Canadian Borrower and such Canadian Lender.

                  Canadian Borrower hereby  renounces,  and shall not claim, any
days of grace for the payment of any Bankers' Acceptances.

         D.       Acceptance and Purchase of Drafts.

                  Not later  than  11:00 A.M.  (Toronto  time) on an  applicable
Drawing Date,  each Canadian  Lender shall complete  Drafts,  dated such Drawing
Date,  with the maturity  date and  denominations  specified  in the  applicable
Drawing Notice,  and following  fulfillment of any applicable  conditions and as
specified  in the  applicable  Drawing  Notice,  shall  accept  such  Drafts and
purchase the Bankers'  Acceptances  thereby created for the applicable  Bankers'
Acceptance Purchase Price.

                  Canadian  Borrower  hereby  authorizes each Canadian Lender to
deduct from the amount to be remitted by it to the Canadian Administrative Agent
in respect of the Bankers'  Acceptance Purchase Price or other purchase price of
any  Bankers'  Acceptance  created by it the BA Fee in respect of such  Bankers'
Acceptance.

                  The failure of any  Canadian  Lender to create and purchase or
deliver  Bankers'  Acceptances  shall not relieve  such  Canadian  Lender of its
obligation,  if any,  to create and  purchase  or deliver  Bankers'  Acceptances
hereunder, but a Canadian Lender shall not be responsible for the failure of any
other Canadian Lender to create and purchase or deliver Bankers'  Acceptances on
any Drawing Date.

         E.       Payment of the Banker's Acceptance Purchase Price and Other 
Purchase Price.

                  Subject to subsection 2.8B and  satisfaction of the conditions
set forth in subsection 3.4, each Canadian  Lender shall,  (i) before 12:00 noon
(Toronto  time)  on the  applicable  Drawing  Date in the  case of the  Bankers'
Acceptance Purchase Price for each Bankers'  Acceptance  purchased by it or (ii)
upon receipt by it on the applicable  Drawing Date of the purchase price payable
by a third  party  in  respect  of any  Bankers'  Acceptance  created  by it and
purchased by such third party, pay or cause to be paid such amount by depositing
or causing to be deposited such amount (less the applicable BA Fee as aforesaid)
to such account maintained by Canadian  Administrative  Agent as shall have been
notified to such Canadian Lender by Canadian  


                                       67


Administrative  Agent,  in  Canadian  Dollars in same day funds.  Promptly  upon
receipt  of such  funds,  Canadian  Administrative  Agent  shall make such funds
available to Canadian Borrower by debiting such account (or causing such account
to be debited),  and (a) by crediting Canadian  Borrower's account, as specified
by Canadian Borrower in writing to Canadian  Administrative Agent prior thereto,
maintained  with  Canadian  Administrative  Agent (or causing such account to be
credited) with like funds in the aggregate amount of such funds or (b) by wiring
such funds in such  amount to the  account of  Canadian  Borrower  with  another
financial institution specified prior thereto by Canadian Borrower in writing to
Canadian Administrative Agent.

                  Bankers' Acceptances  purchased by a Canadian Lender hereunder
may be held by it for its own account  until  maturity or sold by it at any time
prior  thereto in any  relevant  market  therefor  in Canada,  in such  Canadian
Lender's sole discretion.

         F.       Payment at Maturity.

                  Canadian Borrower shall pay to the applicable Canadian Lender,
and there shall  become due and  payable,  at 12:00 noon  (Toronto  time) on the
maturity date for each  Bankers'  Acceptance,  an amount in Canadian  Dollars in
same day  funds  equal to the  Face  Amount  of such  Bankers'  Acceptance.  The
obligation of Canadian  Borrower to make such payment shall not be prejudiced by
the fact that the holder of any such Bankers'  Acceptance is the Canadian Lender
that accepted such Bankers' Acceptance.

                  If Canadian  Borrower fails to pay to the applicable  Canadian
Lender the Face Amount of any Bankers'  Acceptance  as required by the preceding
paragraph, Canadian Borrower shall be deemed to have given a Notice of Borrowing
to  Canadian  Administrative  Agent and  Administrative  Agent  requesting  such
Canadian  Lender to make a Canadian Base Rate Loan on the date that such payment
is due and payable,  and thereupon such Canadian  Lender shall, as of such date,
make such  Canadian Base Rate Loan to Canadian  Borrower,  the proceeds of which
shall be applied  directly to reimburse such Canadian Lender for the Face Amount
of such Bankers' Acceptance paid by it. Canadian  Administrative Agent will give
to Canadian  Borrower  notice of any such action promptly after any such action;
provided,  however,  that the  failure  to give such  notice  shall not limit or
otherwise affect the obligations of Company or any Borrower under this Agreement
or any other Loan Document.

         Bankers' Acceptances may not be prepaid.

         G.       Powers of Attorney.

                  To enable  Canadian  Lenders to complete Drafts and create and
purchase  Bankers'  Acceptances in the manner  specified in this subsection 2.8,
Canadian Borrower shall supply each Canadian Lender with an irrevocable Power of
Attorney satisfactory in form and content to the Canadian  Administrative Agent,
duly  endorsed and  executed on behalf of Canadian  Borrower  allowing  Canadian
Lenders to take such actions.  Notwithstanding that any of the individuals whose
signature appears on any Power of Attorney may no longer hold office at the date
thereof or at any time  thereafter,  any Power of  Attorney  so signed  shall be
valid and binding upon Canadian Borrower.


                                       68


         H.       Circumstances Making Bankers' Acceptances Unavailable.

                  If Canadian  Administrative  Agent  determines  in good faith,
which  determination  shall be  final,  conclusive  and  binding  upon  Canadian

Letter of Credit  shall have  presented,  or shall be  entitled  at such time to

deposit as cash  collateral  as  aforesaid  as shall  equal the  maximum  amount
available  at any time for drawing  under all  Letters of Credit  (the  "Maximum
Available Amount"); provided that, in the event of cancellation or expiration of
any Letter of Credit or any  reduction  in the  Maximum  Available  Amount,  the
applicable  Issuing  Lender  shall  apply the  difference  between  the  Maximum
Available Amount immediately prior to such cancellation, expiration or reduction
and  the  Maximum  Available  Amount  immediately  after  such  cancellation  or
reduction,  first,  to the payment in full of the outstanding  Obligations,  and
second, to Company or the applicable Borrower or to such other Person who may be
lawfully entitled to receive such funds or as a court of competent  jurisdiction
may direct.

                  Any amounts  described in clause (y) above,  when  received by
Canadian Administrative Agent, shall be held by Canadian Administrative Agent in
a collateral  account over which Canadian  Administrative  Agent shall have sole
dominion and control upon terms that are customary to cash  collateral  accounts
maintained  with  Canadian  Administrative  Agent,  as cash  collateral  for the
obligation of Canadian  Borrower to pay the amount of such Bankers'  Acceptances
at maturity,  and at the  maturity of each such  Bankers'  Acceptance,  Canadian
Administrative  Agent shall apply such amounts held pursuant to the terms of the
collateral  account  agreement to the payment thereof.  Canadian Borrower hereby
grants Canadian  Administrative Agent a security interest in any such collateral
account and all funds on deposit therein.


                                      101

principal of any Gold Loan has been declared to be immediately  due and payable,
each U.S.  Lender  shall be  entitled,  for and on behalf of U.S.  Borrower,  to
purchase in  accordance  with its normal  procedures  a number of Ounces of Gold
equal to the number of Ounces of Gold then  comprising  such Gold  Loan,  and to
apply the Gold so purchased to pay such Gold Loan.  The all-in costs to any U.S.
Lender of purchasing such Gold,  provided that any costs incurred are reasonable
in the  circumstances,  shall be  deemed  to be a U.S.  Base  Rate  Loan to U.S.
Borrower.  A certificate  of a U.S.  Lender as to any such all-in costs shall be
prima facie evidence of the costs to such U.S. Lender of making such purchase.

or otherwise)  (including amounts that would become due but for the operation of
the  automatic  stay under  Section  362(a) of the  Bankruptcy  Code,  11 U.S.C.
ss.362(a)  or  operation  of any such  stay  under  applicable  Canadian  and/or
Australian law) of all Obligations of Borrowers (including,  without limitation,
interest  which,  but for the filing of a petition in bankruptcy with respect to
U.S.  Borrower,  or a similar  action with  respect to Canadian  Borrower or any
Australian  Borrower,  would accrue on such  Obligations).  For purposes of this
Section 8, the  obligations of Company under this subsection 8.1 are referred to
as this "Company Guaranty."

         B.       Terms of Company Guaranty

                  Company  agrees that the  Obligations  of any  Borrower may be
extended or renewed,  and the Loans repaid and  reborrowed  in whole or in part,
without  notice or further  assent from it, and that it will  remain  bound upon
this Company Guaranty notwithstanding any extension, renewal or other alteration
of any such Obligation or repayment and reborrowing of the Loans.

                  Company  waives  presentation  of, demand of, payment from and
protest of any  Obligation of any Borrower and also waives notice of protest for
nonpayment.  The obligations of Company under this Company Guaranty shall not be
affected by, and Company  hereby  waives its rights (to the extent  permitted by
law) in connection with:

                                      102


                  (a) the failure of any Agent or any Lender to assert any claim
                  or  demand or to  enforce  any  right or  remedy  against  any
                  Borrower or Company under the  provisions of this Agreement or
                  any other agreement or otherwise,

                  (b)      any extension or renewal of any provision thereof,

                  (c) any rescission,  waiver,  amendment or modification of any
                  of the terms or provisions of this Agreement or any instrument
                  executed pursuant hereto,

                  (d)      the release of any security held by any Agent or any
                  Lender for the Obligations of any Borrower,

                  (e) the  failure  of any Agent or any Lender to  exercise  any
                  right or remedy against any other guarantor of the Obligations
                  of any Borrower,

                  (f) any Agent or any Lender  taking and  holding  security  or
                  collateral for the payment of this Company Guaranty, any other
                  guaranties  of the  Obligations  or other  liabilities  of any
                  Borrower   and  the   Obligations   guarantied   hereby,   and
                  exchanging, enforcing, waiving and releasing any such security
                  or collateral,

                  (g) any Agent or any  Lender  applying  any such  security  or
                  collateral  and  directing the order or manner of sale thereof
                  as such Agent or such Lender in its discretion may determine,

                  (h) any Agent or any Lender settling, releasing, compromising,
                  collecting or otherwise  liquidating  the  Obligations and any
                  security or  collateral  therefor in any manner  determined by
                  such Agent or such Lender, or

                  (i) any  defenses  or  benefits  that may be  derived  from or
                  afforded  by law which  limit the  liability  of or  exonerate
                  guarantors  or sureties,  or which may conflict with the terms
                  of this guaranty, including without limitation, the provisions
                  of California  Civil Code Sections  2809,  2810,  2819,  2839,
                  2845, 2846, 2849, 2850, 2899 and 3433.

                  Without  limiting the generality of the foregoing or any other
provision of this Company Guaranty,  Company hereby waives any rights,  defenses
and benefits  which might  otherwise be  available to Company  under  California
Civil Code Sections 2787 to 2855, inclusive, and any successor sections. Company
acknowledges and agrees that all waivers of defenses arising from any impairment
of   Company's   rights  of   subrogation,   reimbursement,   contribution   and
indemnification  and  waivers  of any  other  rights,  privileges,  defenses  or
protections available to Company by reasons of Sections 2787 to 2855, inclusive,
of the  California  Civil Code are  intended by Company to be  effective  to the
maximum extent  permitted by Section 2856 of the California Civil Code and other
applicable law.

                  Company further agrees that this Company Guaranty  constitutes
a guaranty  of payment  when due and not of  collection  and waives any right to
require  that any resort be had by 

                                      103


any Lender,  any Agent or any other Person to any  security  held for payment of
the  Obligations  of any  Borrower or to any  balance of any deposit  account or
credit on the books of any Lender, any Agent or any other Person in favor of any
Borrower or any other Person.

                  The  obligations of Company under this Company  Guaranty shall
not be subject to any reduction,  limitation,  impairment or termination for any
reason, including,  without limitation, any claim of waiver, release, surrender,
alteration  or  compromise,  and shall not be subject to any  defense or setoff,
counterclaim,  recoupment or termination whatsoever by reason of the invalidity,
illegality or  unenforceability  of the  Obligations,  discharge of any Borrower
from the Obligations in a bankruptcy or similar proceeding or otherwise. Without
limiting the generality of the foregoing,  the obligations of Company under this
Company  Guaranty  shall not be discharged or impaired or otherwise  affected by
the  failure  of any Agent or any  Lender  to  assert  any claim or demand or to
enforce  any  remedy  under  this  Agreement,  any Loan  Document  or any  other
agreement,  by any  waiver or  modification  of any  provision  thereof,  by any
default,  failure or delay,  willful or  otherwise,  in the  performance  of the
Obligations  of any Borrower,  or by any other act or thing or omission or delay
to do any other act or thing  that may or might in any  manner or to any  extent
vary the risk of Company or would otherwise operate as a discharge of Company as
a  matter  of law or  equity  other  than  indefeasible  payment  in full of all
Obligations.

                  Any Agent and any Lender may, at their election,  foreclose on
any  security  held by such  Agent or such  Lender  by one or more  judicial  or
nonjudicial sales, or exercise any other right or remedy any Agent or any Lender
may have against any Borrower or any security without  affecting or impairing in
any way the liability of Company  hereunder except to the extent the Obligations
have been  indefeasibly  paid.  Company  waives any defense  arising out of such
election by any Agent or any  Lender,  even  though  such  election  operates to
impair or extinguish any right of reimbursement or subrogation or other right or
remedy of Company against any Borrower or any security, so long as such Agent or
such Lender act in a commercially reasonable manner.

                  Company  further  agrees  that  this  Company  Guaranty  shall
continue to be  effective or be  reinstated,  as the case may be, if at any time
payment,  or any part thereof,  of principal of or interest on any Obligation of
any  Borrower is  rescinded  or must  otherwise  be restored by any Agent or any
Lender upon the bankruptcy or reorganization of any Borrower or otherwise.

                  Company  further  agrees,  in furtherance of the foregoing and
not in  limitation  of any other  right that any Agent or any Lender may have at
law or in equity  against  Company  by virtue  hereof,  upon the  failure of any
Borrower  to pay any of its  Obligations  when and as the same shall  become due
(whether by required prepayment, declaration, demand or otherwise), Company will
forthwith pay, or cause to be paid, in cash, to  Administrative  Agent an amount
equal to the sum of the unpaid principal amount of such Obligations, accrued and
unpaid  interest on such  Obligations  and all other unpaid  Obligations of such
Borrower to any Agent or any Lender.

                  Company  hereby   irrevocably   agrees  to  waive,  until  the
Obligations  have been paid in full and the Commitments  shall have  terminated,
any exercise of any right of subrogation,  contribution,  indemnity or otherwise
against  any  Borrower  that  may  arise  out of or be  caused  by 

                                      104


this Company  Guaranty,  all rights  and/or  claims which may arise  against any
Borrower  by reason of this  Company  Guaranty,  any right to enforce any remedy
that any Agent or any Lender now has or may hereafter  have against any Borrower
and any  benefit  of,  and any right to  participate  in,  any  security  now or
hereafter held by any Agent or any Lender.

                   Any  Indebtedness  of any of Company's  Subsidiaries  held by
Company is hereby  subordinated  in right of payment to the  Obligations  on the
terms of this paragraph.  Upon the occurrence and during the  continuation of an
Event of Default,  no distribution of assets in respect of any such Indebtedness
(including  any  payment  of  principal,  interest  or fees  or any  repurchase,
redemption or setoff of such Indebtedness  against other  Indebtedness  owing to
Company or payment received as a result of other Indebtedness being subordinated
to such Indebtedness) may be made until indefeasible  payment in full in cash of
all  Obligations.   If,   notwithstanding  the  preceding  sentence,   any  such
distribution  of assets  shall be  collected  or received  by Company  after the
occurrence and during the continuation of an Event of Default, such distribution
of assets shall be paid over to Administrative  Agent for the benefit of Lenders
to be held as collateral and then or thereafter credited and applied against the
Obligations  but without  impairing  or limiting in any manner the  liability of
Company under any other provision of this Section 8.

                  In  addition  to any rights  now or  hereafter  granted  under
applicable law and not by way of limitation of any such rights, upon any failure
of any Borrower to pay its Obligations when due (whether by required prepayment,
declaration, demand or otherwise) and consequent acceleration of the Obligations
pursuant  to  Section  7,  any  Agent  and  any  Lender,  upon  the  consent  of
Administrative  Agent and Requisite Lenders,  is hereby authorized by Company at
any time or from time to time, without notice to Company or to any other Person,
any such  notice  being  hereby  expressly  waived to the  extent  permitted  by
applicable  law, to set off and to appropriate and to apply any and all deposits
(general or special,  including,  but not limited to, Indebtedness  evidenced by
certificates of deposit,  whether matured or unmatured,  but not including trust
accounts)  and any other  Indebtedness  at any time  owing by such Agent or such
Lender to or for the credit or the account of Company  against and on account of
the  obligations  and  liabilities of Company to such Agent or such Lender under
this Company Guaranty,  including,  but not limited to, all such obligations and
liabilities with respect to all claims of any nature or description  arising out
of or connected  with this  Agreement,  this Company  Guaranty or the Letters of
Credit or Bankers' Acceptances or any of the other Loan Documents,  irrespective
of  whether  or not such  Agent or such  Lender or  Administrative  Agent,  with
respect to any Obligation owed under the Letters of Credit, Bankers' Acceptances
or this Agreement, shall have made any demand hereunder.

8.2      Guaranty by U.S. Borrower

                  A. Guaranty.  As  consideration  for Lenders agreeing to enter
into this  Agreement  and to extend  the  Overall  Commitments  hereunder,  U.S.
Borrower hereby unconditionally and irrevocably guarantees, as a primary obligor
and not merely as a surety, and jointly and severally with Company as it relates
to the Obligations of Canadian  Borrower and Australian  Borrowers,  the due and
punctual payment when due (whether by required prepayment,  declaration,  demand
or otherwise)  (including amounts that would become due but for the

                                      105


operation of the automatic stay under Section 362(a) of the Bankruptcy  Code, 11
U.S.C.  ss.362(a) or operation of any such stay under applicable Canadian and/or
Australian law) of all Obligations of Canadian Borrower and Australian Borrowers
(including, without limitation, interest which, but for the filing of a petition
in  bankruptcy  or a similar  action with  respect to  Canadian  Borrower or any
Australian  Borrower,  would accrue on such  Obligations).  For purposes of this
Section  8, the  obligations  of U.S.  Borrower  under this  subsection  8.2 are
referred to as this "U.S. Borrower Guaranty."

         B.       Terms of U.S. Borrower Guaranty

                  U.S. Borrower agrees that the Obligations of Canadian Borrower
and  Australian  Borrowers may be extended or renewed,  and the Loans repaid and
reborrowed in whole or in part,  without  notice or further  assent from it, and
that it will remain bound upon this U.S. Borrower Guaranty  notwithstanding  any
extension,  renewal or other  alteration of any such Obligation or repayment and
reborrowing of the Loans.

                  U.S. Borrower waives  presentation of, demand of, payment from
and protest of any Obligation of Canadian  Borrower or any  Australian  Borrower
and also  waives  notice of protest  for  nonpayment.  The  obligations  of U.S.
Borrower  under this U.S.  Borrower  Guaranty shall not be affected by, and U.S.
Borrower hereby waives its rights (to the extent permitted by law) in connection
with:

                  (a) the failure of any Agent or any Lender to assert any claim
                  or demand or to enforce any right or remedy  against  Canadian
                  Borrower,  any Australian  Borrower or U.S. Borrower under the
                  provisions  of  this  Agreement  or  any  other  agreement  or
                  otherwise,

                  (b)      any extension or renewal of any provision thereof,

                  (c) any rescission,  waiver,  amendment or modification of any
                  of the terms or provisions of this Agreement or any instrument
                  executed pursuant hereto, (d) the release of any security held
                  by any Agent or any Lender  for the  Obligations  of  Canadian
                  Borrower or any Australian Borrower,

                  (e) the  failure  of any Agent or any Lender to  exercise  any
                  right or remedy against any other guarantor of the Obligations
                  of Canadian Borrower or any Australian Borrower,

                  (f) any Agent or any Lender  taking and  holding  security  or
                  collateral for the payment of this U.S. Borrower Guaranty, any
                  other  guaranties of the  Obligations or other  liabilities of
                  Canadian   Borrower  or  any   Australian   Borrower  and  the
                  Obligations  guarantied  hereby,  and  exchanging,  enforcing,
                  waiving and releasing any such security or collateral,

                                    106


                  (g) any Agent or any  Lender  applying  any such  security  or
                  collateral  and  directing the order or manner of sale thereof
                  as such Agent or such Lender in its discretion may determine,

                  (h) any Agent or any Lender settling, releasing, compromising,
                  collecting  or  otherwise   liquidating   the  Obligations  of
                  Canadian Borrower or any Australian  Borrower and any security
                  or collateral  therefor in any manner determined by such Agent
                  or such Lender, or

                  (i) any  defenses  or  benefits  that may be  derived  from or
                  afforded  by law which  limit the  liability  of or  exonerate
                  guarantors  or sureties,  or which may conflict with the terms
                  of this guaranty, including without limitation, the provisions
                  of California  Civil Code Sections  2809,  2810,  2819,  2839,
                  2845, 2846, 2849, 2850, 2899 and 3433.

                  Without  limiting the generality of the foregoing or any other
provision  of this U.S.  Borrower  Guaranty,  U.S.  Borrower  hereby  waives any
rights,  defenses  and  benefits  which might  otherwise  be  available  to U.S.
Borrower under California Civil Code Sections 2787 to 2855,  inclusive,  and any
successor  sections.  U.S. Borrower  acknowledges and agrees that all waivers of
defenses arising from any impairment of U.S.  Borrower's  rights of subrogation,
reimbursement, contribution and indemnification and waivers of any other rights,
privileges,  defenses or  protections  available to U.S.  Borrower by reasons of
Sections 2787 to 2855,  inclusive,  of the California Civil Code are intended by
U.S. Borrower to be effective to the maximum extent permitted by Section 2856 of
the California Civil Code and other applicable law.

                  U.S.  Borrower further agrees that this U.S. Borrower Guaranty
constitutes a guaranty of payment when due and not of collection  and waives any
right to require  that any resort be had by any  Lender,  any Agent or any other
Person to any security held for payment of the Obligations of Canadian  Borrower
or any Australian Borrower or to any balance of any deposit account or credit on
the books of any  Lender,  any Agent or any  other  Person in favor of  Canadian
Borrower or any Australian Borrower or any other Person.

                  The  obligations  of U.S.  Borrower  under this U.S.  Borrower
Guaranty  shall not be  subject  to any  reduction,  limitation,  impairment  or
termination for any reason, including,  without limitation, any claim of waiver,
release,  surrender,  alteration or compromise,  and shall not be subject to any
defense or setoff, counterclaim,  recoupment or termination whatsoever by reason
of the invalidity, illegality or unenforceability of the Obligations,  discharge
of Canadian  Borrower  or any  Australian  Borrower  from the  Obligations  in a
bankruptcy or similar  proceeding or otherwise.  Without limiting the generality
of the  foregoing,  the  obligations of U.S.  Borrower under this U.S.  Borrower
Guaranty  shall not be  discharged  or  impaired  or  otherwise  affected by the
failure  of any Agent or any  Lender to assert any claim or demand or to enforce
any remedy under this Agreement,  any Loan Document or any other  agreement,  by
any waiver or modification of any provision thereof, by any default,  failure or
delay,  willful or otherwise,  in the performance of the Obligations of Canadian
Borrower or any Australian Borrower, or by any other act or thing or omission or
delay to do any  other  act or thing  that may or might in any  manner or to any
extent 

                                      107


vary the risk of U.S. Borrower or would otherwise operate as a discharge of U.S.
Borrower as a matter of law or equity other than indefeasible payment in full of
all Obligations.

                  Any Agent and any Lender may, at their election,  foreclose on
any  security  held by such  Agent or such  Lender  by one or more  judicial  or
nonjudicial sales, or exercise any other right or remedy any Agent or any Lender
may have against  Canadian  Borrower or any Australian  Borrower or any security
without  affecting  or  impairing  in any way  the  liability  of U.S.  Borrower
hereunder  except  to the  extent  the  Obligations  of  Canadian  Borrower  and
Australian  Borrowers have been  indefeasibly  paid.  U.S.  Borrower  waives any
defense  arising out of such  election  by any Agent or any Lender,  even though
such election  operates to impair or extinguish  any right of  reimbursement  or
subrogation or other right or remedy of U.S.  Borrower against Canadian Borrower
or any Australian Borrower or any security,  so long as any Agent or such Lender
act in a commercially reasonable manner.

                  U.S.  Borrower further agrees that this U.S. Borrower Guaranty
shall continue to be effective or be  reinstated,  as the case may be, if at any
time payment, or any part thereof, of principal of or interest on any Obligation
of Canadian  Borrower or any Australian  Borrower is rescinded or must otherwise
be restored by any Agent or any Lender upon the bankruptcy or  reorganization of
Canadian Borrower or any Australian Borrower or otherwise.

                  U.S.  Borrower further agrees, in furtherance of the foregoing
and not in  limitation  of any other right that any Agent or any Lender may have
at law or in equity  against  Company  by virtue  hereof,  upon the  failure  of
Canadian Borrower or any Australian  Borrower to pay any of its Obligations when
and as the same shall become due (whether by required  prepayment,  declaration,
demand or otherwise),  U.S. Borrower will forthwith pay, or cause to be paid, in
cash, to Administrative Agent an amount equal to the sum of the unpaid principal
amount of such Obligations,  accrued and unpaid interest on such Obligations and
all other unpaid  Obligations of Canadian  Borrower and Australian  Borrowers to
any Agent or any Lender.

                  U.S. Borrower hereby irrevocably waives, until the Obligations
have been paid in full and the Commitments  shall have terminated,  any right of
subrogation,  contribution,  indemnity or otherwise against Canadian Borrower or
any Australian Borrower that may arise out of or be caused by this U.S. Borrower
Guaranty,  all rights and/or claims which may arise against Canadian Borrower or
any Australian  Borrower by reason of this U.S. Borrower Guaranty,  any right to
enforce  any remedy that any Agent or any Lender now has or may  hereafter  have
against Canadian Borrower or any Australian Borrower and any benefit of, and any
right to participate  in, any security now or hereafter held by any Agent or any
Lender.

                  Any Indebtedness of Company or any of its Subsidiaries held by
U.S.  Borrower is hereby  subordinated in right of payment to the Obligations on
the terms of this paragraph.  Upon the occurrence and during the continuation of
an  Event  of  Default,  no  distribution  of  assets  in  respect  of any  such
Indebtedness  (including  any  payment  of  principal,  interest  or fees or any
repurchase, redemption or setoff of such Indebtedness against other Indebtedness
owing to U.S.  Borrower or payment  received  as a result of other  Indebtedness
being subordinated to such Indebtedness) may be made until indefeasible  payment
in full in cash of all Obligations.  If, 


                                      108


notwithstanding the preceding sentence, any such distribution of assets shall be
collected  or  received by U.S.  Borrower  after the  occurrence  and during the
continuation of an Event of Default,  such  distribution of assets shall be paid
over to Administrative Agent for the benefit of Lenders to be held as collateral
and then or thereafter  credited and applied against the Obligations but without
impairing  or limiting in any manner the  liability of U.S.  Borrower  under any
other provision of this Section 8.

                  In  addition  to any rights  now or  hereafter  granted  under
applicable law and not by way of limitation of any such rights, upon any failure
of Canadian Borrower or any Australian  Borrower to pay its Obligations when due
(whether  by  required  prepayment,   declaration,   demand  or  otherwise)  and
consequent  acceleration of the Obligations pursuant to Section 7, any Agent and
any Lender,  upon the consent of Administrative  Agent and Requisite Lenders, is
hereby  authorized  by U.S.  Borrower at any time or from time to time,  without
notice to U.S.  Borrower or to any other  Person,  any such notice  being hereby
expressly  waived to the extent  permitted by applicable  law, to set off and to
appropriate  and to apply any and all deposits  (general or special,  including,
but not limited to, Indebtedness  evidenced by certificates of deposit,  whether
matured  or  unmatured,   but  not  including  trust  accounts)  and  any  other
Indebtedness at any time owing by such Agent or such Lender to or for the credit
or the account of U.S.  Borrower  against and on account of the  obligations and
liabilities  of U.S.  Borrower  to such  Agent or such  Lender  under  this U.S.
Borrower  Guaranty,  including,  but not  limited to, all such  obligations  and
liabilities with respect to all claims of any nature or description  arising out
of or connected with this Agreement,  this U.S. Borrower Guaranty or the Letters
of  Credit  or  Bankers'  Acceptances  or  any  of  the  other  Loan  Documents,
irrespective  of  whether  or not such  Agent or such  Lender or  Administrative
Agent, with respect to any Obligation owed under the Letters of Credit, Bankers'
Acceptances or this Agreement, shall have made any demand hereunder.

accordance with the terms of this Agreement and the other Loan  Documents.  Each
Agent agrees to act upon the express conditions  contained in this Agreement and
the other Loan Documents,  as applicable.  Except as expressly set forth in this
Section 9, the provisions of this Section 9 are solely for the benefit of Agents
and Lenders,  and neither  Company nor any  Borrower  shall have any rights as a
third  party  beneficiary  of any of the  provisions  hereof,  but  Company  and
Borrowers shall have the rights expressly  granted to them in subsection 9.6. In
performing its functions and duties under this  Agreement,  each Agent shall act
solely as an agent of  Lenders  and

                                      109


does not assume and shall not be deemed to have assumed any  obligation  towards
or relationship of agency or trust with or for Company or any Borrower or any of
Company's Subsidiaries.

9.2      Powers; General Immunity.

                  A. Duties Specified.  Each Lender irrevocably  authorizes each
Agent to take such action on such  Lender's  behalf and to exercise  such powers
under this  Agreement  and under the other Loan  Documents  as are  specifically
delegated  to such Agent by the terms  hereof and  thereof,  together  with such
powers as are reasonably  incidental  thereto.  Each Agent shall have only those
duties and  responsibilities  that are expressly specified in this Agreement and
the other Loan  Documents  and each such  Agent may  perform  such  duties by or
through  its  agents  or  employees.  No Agent  shall  have,  by  reason of this
Agreement  or any of the other  Loan  Documents,  a  fiduciary  relationship  in
respect of any Lender;  and nothing in this  Agreement  or any of the other Loan
Documents,  express or implied,  is intended to or shall be so  construed  as to
impose upon such Agent any  obligations  in respect of this  Agreement or any of
the other Loan Documents except as expressly set forth herein or therein.

                  B. No  Responsibility  for Certain Matters.  No Agent shall be
responsible  to  any  Lender  for  the  execution,  effectiveness,  genuineness,
validity, enforceability, collectibility or sufficiency of this Agreement or any
other  Loan  Document  or  for  any  representations,  warranties,  recitals  or
statements made herein or therein or made in any written or oral statement or in
any financial or other statements,  instruments,  reports or certificates or any
other documents  furnished or made available by any Agent to Lenders or by or on
behalf of Company or  Borrowers to such Agent or any Lender in  connection  with
the  Loan  Documents  and  the  transactions  contemplated  thereby  or for  the
financial  condition or business  affairs of Company,  any Borrower or any other
Person  liable  for the  payment  of any  Obligations,  nor  shall  any Agent be
required to ascertain or inquire as to the  performance  or observance of any of
the terms, conditions,  provisions,  covenants or agreements contained in any of
the Loan  Documents  or as to the use of the  proceeds  of the Loans or Bankers'
Acceptances  or the use of Letters of Credit or as to the  existence or possible
existence  of any Event of  Default  or  Potential  Event of  Default.  Anything
contained in this Agreement to the contrary notwithstanding, no Agent shall have
any liability  arising from  confirmations of the amount of outstanding Loans or
the  Canadian  Letter of Credit  Usage,  the U.S.  Letter of Credit  Usage,  the
Australian  Letter  of  Credit  Usage,  the BA  Usage or the  component  amounts
thereof.

                  C. Exculpatory Provisions.  No Agent and none of its officers,
directors,  employees  or agents shall be liable to Lenders for any action taken
or omitted by such  Agent  hereunder  or in  connection  herewith  except to the
extent caused by its or their gross negligence or willful misconduct, as finally
determined  by a court of  competent  jurisdiction.  If any Agent shall  request
instructions  from  Lenders  with  respect to any act or action  (including  the
failure to take an action) in connection with this Agreement or any of the other
Loan Documents,  such Agent shall be entitled to refrain from such act or taking
such action  unless and until such Agent shall have received  instructions  from
Requisite  Lenders or all Lenders,  as the case may be. Without prejudice to the
generality of the foregoing, (i) each Agent shall be entitled to rely, and shall
be fully protected in relying,  upon any  communication,  instrument or document
believed to be 


                                      110


genuine  and  correct  and to have been  signed or sent by the proper  person or
persons,  and shall be  entitled  to rely and shall be  protected  in relying on
opinions  and  judgments  of  attorneys  (who may be  attorneys  for Company and
Borrower   and   Company's   Subsidiaries),   accountants,   experts  and  other
professional advisors selected by any of them; and (ii) no Lender shall have any
right of action whatsoever against any Agent as a result of such Agent acting or
(where so instructed)  refraining from acting under this Agreement or any of the
other Loan Documents in accordance with the instructions of Requisite Lenders or
all  Lenders,  as the case may be. Each Agent shall be entitled to refrain  from
exercising any power,  discretion or authority vested in it under this Agreement
or any of the  other  Loan  Documents  unless  and  until  it has  obtained  the
instructions of Requisite Lenders or all Lenders, as the case may be.

                  D.  Agents  Entitled  to Act as  Lenders.  The  agency  hereby
created  shall in no way  impair or affect  any of the  rights and powers of, or
impose any duties or obligations upon, any Agent in its individual capacity as a
Lender under this  Agreement.  With respect to its  participation  in the Loans,
Letters  of Credit and  Bankers'  Acceptances,  each  Agent  shall have the same
rights and powers under this  Agreement as any other Lender and may exercise the
same as though it were not performing  the duties and functions  delegated to it
hereunder,  and the term "Lender" or "Lenders" or any similar term shall, unless
the context clearly  otherwise  indicates,  include each Agent in its individual
capacity.  Each Agent and each of its Affiliates may accept  deposits from, lend
money to and generally engage in any kind of banking,  trust, financial advisory
or other business with Company,  any Borrower or any of Company's  Affiliates as
if it were not performing the duties specified  herein,  and may accept fees and
other  consideration  from Company and Borrowers for services in connection with
this Agreement and otherwise without having to account for the same to Lenders.

9.3      Representations and Warranties; No Responsibility For Appraisal of
Creditworthiness.

                  Each Lender  represents  and warrants that it has made its own
independent  investigation  of the  financial  condition and affairs of Company,
each Borrower and Company's  Subsidiaries  in connection  with the making of the
Loans  hereunder  and the  issuance  of  Letters  of Credit  hereunder  and such
Lender's purchasing of participations in such Letters of Credit and, in the case
of each Canadian Lender, the creation and purchase of Bankers' Acceptances,  and
that  it  has  made  and  shall  continue  to  make  its  own  appraisal  of the
creditworthiness of Company, each Borrower and Company's Subsidiaries.  No Agent
shall  have any duty or  responsibility,  either  initially  or on a  continuing
basis, to make any such investigation or any such appraisal on behalf of Lenders
or to provide  any  Lender  with any credit or other  information  with  respect
thereto,  whether coming into its  possession  before the making of the Loans or
the  issuance of the Letters of Credit or the  creation and purchase of Bankers'
Acceptances  or at any time or times  thereafter,  and no Agent  shall  have any
responsibility  with  respect  to the  accuracy  of or the  completeness  of any
information provided to Lenders. 

                                      111


9.4 Right to Indemnity.

                  The  Lenders  of each  Lending  Unit in  proportion  to  their
Lending Unit's Pro Rata Share,  severally with the Lenders of each other Lending
Unit agree to indemnify each Agent (and their  respective  directors,  officers,
employees and agents), to the extent that such Agent (or any of their respective
directors,  officers,  employees and agents)  shall not have been  reimbursed by
Company or  Borrowers,  for and  against any and all  liabilities,  obligations,
losses,  damages,   penalties,   actions,   judgments,  suits,  costs,  expenses
(including, without limitation, counsel fees and disbursements) or disbursements
of any kind or  nature  whatsoever  which  may be  imposed  on,  incurred  by or
asserted against such Agent (or their respective directors,  officers, employees
and agents) in performing  its duties  hereunder or under this  Agreement or the
other Loan  Documents  or  otherwise  in its  capacity  as such Agent in any way
relating  to or  arising  out of this  Agreement  or the other  Loan  Documents;
provided  that no Lender  shall be liable for any  portion of such  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or  disbursements  resulting from such Agent's (or any such director's,
officer's,  employee's or agent's) gross  negligence or willful  misconduct,  as
finally  determined  by a court  of  competent  jurisdiction.  If any  indemnity
furnished to any Agent for any purpose shall,  in the opinion of such Agent,  be
insufficient or become  impaired,  such Agent may call for additional  indemnity
and  cease,  or not  commence,  to do the acts  indemnified  against  until such
additional  indemnity is furnished but shall not include any losses  suffered by
an Agent under subsection  2.1C(iv) or otherwise as a result of another Lender's
default hereunder.

9.5      Registered Persons Treated as Owners.

                  Each Agent may deem and treat the Persons listed as Lenders in
the  Register  as the owners of the  corresponding  Loans or  participations  in
Letters of Credit or Bankers' Acceptances listed therein for all purposes hereof
unless and until an  Assignment  and  Acceptance  effecting  the  assignment  or
transfer thereof shall have been accepted by  Administrative  Agent and recorded
in the  Register as provided in  subsection  10.1B(ii)  of this  Agreement.  Any
request,  authority  or consent of any Person  who,  at the time of making  such
request or giving  such  authority  or consent,  is listed in the  Register as a
Lender shall be conclusive and binding on any subsequent  holder,  transferee or
assignee  of the  corresponding  Loan or  participation  in Letters of Credit or
Bankers' Acceptance.

9.6      Successor Agents.

                  Any  Agent may  resign  at any time by  giving 30 days'  prior
written notice thereof to Lenders,  Company and Borrowers, and such Agent may be
removed  at any time  with or  without  cause  by an  instrument  or  concurrent
instruments  in  writing  delivered  to  Company,   Borrowers,  such  Agent  and
Administrative  Agent as the case may be, and signed by Requisite Lenders.  Upon
any such notice of resignation or any such removal, Requisite Lenders shall have
the right, upon five Business Days' notice to Company and Borrowers,  to appoint
a successor  Agent;  provided  that if such  proposed  successor  Agent is not a
Lender,  Company and Borrowers shall have the right to approve such  appointment
(which  approval  may  not  be  unreasonably  withheld  or  delayed).  Upon  the
acceptance of any appointment as an Agent hereunder by a 

                                      112



successor  Agent,  that successor  Agent shall  thereupon  succeed to and become
vested with all the rights,  powers,  privileges  and duties of the  retiring or
removed  Agent and the retiring or removed  Agent shall be  discharged  from its
duties and  obligations  under this  Agreement.  After any  retiring  or removed
Agent's  resignation  or removal  hereunder as an Agent,  the provisions of this
subsection  9.6 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was such an Agent under this Agreement.


Section 10.  MISCELLANEOUS


10.1  Assignments of and  Participations  in  Commitments,  Loans and Letters of
Credit.

                  A.  General.  The Lenders in each  Lending Unit shall have the
right at any time to (i) sell,  assign,  transfer or  negotiate  to any Eligible
Assignee and its  Affiliates  which,  subject to the  provisions  of  subsection
2.1(A)(iv) and subsection 2.1E, has (a) a Canadian Lending Office for borrowings
and  payments  relating  to Canadian  Loans and  Bankers'  Acceptances,  if such
Lending Unit has a Canadian  Commitment,  (b) an Australian  Lending  Office for
borrowings and payments  relating to Australian  Loans, if such Lending Unit has
an Australian  Commitment,  and (c) a U.S.  Lending  Office for  borrowings  and

Australian  Commitment even if such Lending Unit does not have such  Commitments
or (ii) sell  participations  to any  Person  in, all or any part of any Loan or
Loans  made  by it or its  Overall  Commitments  or its  Letters  of  Credit  or
participations therein, or any other interest herein or in any other Obligations
owed to it; provided that no such assignment or participation shall, without the
consent of Company  and  Borrowers,  require  Company or any  Borrower to file a
registration  statement with the Securities and Exchange  Commission or apply to
qualify  such  assignment  or  participation  under the  securities  laws of any
jurisdiction;  and  provided,  further  that  for  greater  certainty,  Bankers'
Acceptances  purchased  by a  Canadian  Lender  may be held or sold by it in its
absolute discretion as provided in subsection 2.8E. Except as otherwise provided
in this  subsection  10.1,  no Lender  shall,  as between any  Borrower and such
Lender, be relieved of any of its obligations hereunder as a result of any sale,
assignment,  transfer or negotiation of, or any granting of  participations  in,
all or any part of the  Loans,  the  Overall  Commitments,  Letters of Credit or
participations  therein or Bankers' Acceptances or the other Obligations owed to

                  (i) Amounts and Terms of Assignments. Each Loan, Commitment or
                  other  Obligation to be assigned  pursuant to subsection 10.1A
                  may (a) be  assigned  in any amount  (of a constant  and not a
                  varying  percentage) to another Lender,  or to an Affiliate of
                  the  assigning  Lender or another  Lender,  with the giving of
                  notice to Company,  Borrowers and Administrative  Agent or (b)

                  percentage) of not less than $5,000,000 (or such lesser amount
                  as shall constitute the aggregate amount of all Loans, Overall
                  Commitments,  Letters of Credit or participations therein, and
                  other  Obligations  of the  assigning  Lender)  to  any  other
                  Eligible  Assignee  with the  giving  of  notice  to  Company,

                                      113




                  Borrowers  and  Agents  and in the case of  assignment  to any
                  other  Eligible   Assignee,   with  the  consent  of  Company,
                  Borrowers and Administrative Agent for an assignment made by a
                  Lender other than  Administrative  Agent, and with the consent
                  of  Company  and   Borrowers   for  an   assignment   made  by
                  Administrative Agent, which consent of Company,  Borrowers and
                  Administrative Agent shall not be unreasonably  withheld,  and
                  which consent of Company and  Borrowers  shall not be required
                  upon the occurrence and during the  continuance of an Event of
                  Default;  provided  that all such  assignments  by any  Lender
                  shall  be  permitted  only  if the  Canadian  Lender,  if any,
                  Australian  Lender,  if any,  and U.S.  Lender of each Lending
                  Unit  simultaneously  assign the same proportionate  shares of
                  their outstanding Loans,  participations in Letters of Credit,
                  and Overall  Commitments to assignees  that will  respectively
                  constitute the Canadian Lender, Australian Lender and the U.S.
                  Lender of a Lending Unit for the  purposes of this  Agreement.
                  To the extent of any such assignment in accordance with either
                  clause  (a)  or (b)  above,  the  assigning  Lender  shall  be
                  relieved of its obligations with respect to its Loans, Overall
                  Commitments,  Letters of Credit or  participations  therein or
                  other  Obligations or the portion thereof so assigned provided
                  that the  assigning  Lender  shall  continue to have rights of
                  indemnity under  subsections  10.2, 10.3 and 10.7. The parties
                  to  each  such   assignment   shall  execute  and  deliver  to
                  Administrative  Agent, for its acceptance and recording in the
                  Register,  an  Assignment  and  Acceptance,  together  with  a
                  processing   and   recordation   fee  of   $3,500,   and  such
                  certificates,  documents  or  other  evidence,  if  any,  with
                  respect to United  States  federal,  Canadian  and  Australian
                  income  tax  withholding  matters as the  assignee  under such
                  Assignment  and  Acceptance  may be  required  to  deliver  to
                  Administrative Agent pursuant to subsection  10.7B(iii).  Upon
                  such execution,  delivery and  acceptance,  from and after the
                  effective  date specified in such  Assignment and  Acceptance,
                  (y) the  assignee  thereunder  shall be a party hereto and, to
                  the extent that  rights and  obligations  hereunder  have been
                  assigned  to it pursuant to such  Assignment  and  Acceptance,
                  shall have the rights and  obligations of a Lender  hereunder,
                  and (z) the assigning Lender  thereunder  shall, to the extent
                  that rights and obligations hereunder have been assigned by it
                  pursuant to such  Assignment  and  Acceptance,  relinquish its
                  rights  and  be  released  from  its  obligations  under  this
                  Agreement  (and, in the case of an Assignment  and  Acceptance
                  covering all or the remaining portion of an assigning Lender's
                  rights and obligations under this Agreement, such Lender shall
                  cease to be a party hereto). The Overall Commitments hereunder
                  shall be modified to reflect the  Commitment  of such assignee
                  and any remaining  Commitment of such assigning Lender and, if
                  any such  assignment  occurs after the issuance of a Note or a
                  Grid Gold  Acknowledgement  to the assigning Lender hereunder,
                  if requested  pursuant to subsection  2.1E, new Notes and Grid
                  Gold  Acknowledgements  shall, upon surrender of the assigning
                  Lender's Notes or Grid Gold Acknowledgements, be issued to the
                  assignee and to the  assigning  Lender,  substantially  in the
                  forms of Exhibit  IV-A,  Exhibit IV-B,  Exhibit IV-C,  Exhibit
                  IV-D or  Exhibit V annexed  hereto,  as the case may be,  with
                  appropriate insertions, to reflect the new Overall Commitments
                  of the assignee and the assigning Lender.

                                      114


                  (ii)  Acceptance  by  Administrative  Agent;   Recordation  in
                  Register.  Upon its receipt of an  Assignment  and  Acceptance
                  executed by an assigning  Lender and an assignee  representing
                  that it is an Eligible  Assignee  meeting the  requirements of
                  subsection 10.1A, together with the processing and recordation
                  fee referred to in subsection  10.1B(i) and any  certificates,
                  documents  or other  evidence  with  respect to United  States
                  federal,   Canadian  and  Australian  income  tax  withholding
                  matters  that such  assignee  may be  required  to  deliver to
                  Administrative   Agent  pursuant  to  subsection   10.7B(iii),
                  Administrative  Agent shall, if such Assignment and Acceptance
                  has been completed and is in substantially the form of Exhibit
                  X-A, Exhibit X-B, or Exhibit X-C annexed hereto, as applicable
                  and  if  Administrative  Agent,  Company  and  Borrowers  have
                  consented to the assignment evidenced thereby (in each case to
                  the extent  such  consent is required  pursuant to  subsection
                  10.1B(i)),  (a)  accept  such  Assignment  and  Acceptance  by
                  executing a  counterpart  thereof as provided  therein  (which
                  acceptance    shall   evidence   any   required   consent   of
                  Administrative  Agent  to such  assignment),  (b)  record  the
                  information  contained  therein in the Register,  and (c) give
                  prompt notice thereof to Company, Borrowers and the Applicable
                  Administrative  Agent.  Administrative  Agent shall maintain a
                  copy  of  each  Assignment  and  Acceptance  delivered  to and
                  accepted by it as provided in this subsection 10.1B(ii).

                  C. Participations. The holder of any participation, other than
an Affiliate of the Lender granting such participation, shall not be entitled to
require such Lender to take or omit to take any action  hereunder  except action
directly affecting (i) the extension of the regularly  scheduled maturity of any
portion of the  principal  amount of or interest  on any Loan or any  commitment
fees  allocated  to such  participation,  (ii) the  release  of  Company or U.S.
Borrower  from its  obligations  under  Section  8 or (iii) a  reduction  of the
principal  amount of or the rate of interest payable on any Loan, a reduction in
the Face  Amount,  amount of  discount  or fee on any  Bankers'  Acceptance,  or
payments  due in repayment  of draws under  Letters of Credit  allocated to such
participation,  and all amounts  payable by any  Borrower  or Company  hereunder
shall be determined as if such Lender had not sold such  participation.  Company
and each  Borrower  hereby  acknowledges  and agrees that,  only for purposes of
subsections  2.6D, 10.5 and 10.7, any  participation  will give rise to a direct
obligation of Borrowers and Company to the participant and the participant shall
be considered to be a "Lender";  provided that no participant  shall be entitled
to receive  any greater  amount  pursuant  to  subsection  2.6D or 10.7 than the
transferor  Lender would have been  entitled to receive in respect of the amount
of the participation  effected by such transferor Lender to such participant had
no such participation occurred. Company, Borrowers, Agents and the other Lenders
shall continue to deal solely with such Lender in connection  with such Lender's
rights and obligations under the Loan Documents.

                  D.  Information.  Each  Lender  may  furnish  any  information
concerning  Company and its  Subsidiaries  in the possession of that Lender from
time to time to assignees and participants  (including prospective assignees and
participants), subject to subsection 10.21.

                  E. Federal Reserve Bank. Nothing in this subsection 10.1 shall

under this  Agreement  and/or its  Loans,  participations  in Letters of Credit,
Bankers' Acceptances and/or Notes hereunder to a Federal Reserve Bank.


         F.       The Register.

                  (i)  Administrative  Agent and the  Applicable  Administrative
                  Agent shall maintain,  at its Lending  Office,  a register for
                  the  recordation of the names and addresses of Lenders and the
                  Commitment  and  Loans of each  Lender  from time to time (the
                  "Register").  Borrowers,  Agents  and  Lenders  may treat each
                  Person  whose name is  recorded  in the  Register  as a Lender
                  hereunder  for all  purposes of this  Agreement.  The Register
                  shall be available for  inspection  by Company,  any Borrower,
                  any Agent or any Lender at any  reasonable  time and from time
                  to time upon reasonable prior notice.

                  (ii)  Administrative  Agent and the Applicable  Administrative
                  Agent shall  record in the  Register  the  Commitment  and the
                  Loans from time to time of each Lender and each  repayment  or
                  prepayment in respect of the principal  amount of the Loans of
                  each Lender.  Any such  recordation  shall be  conclusive  and
                  binding on Company and each  Lender,  absent  manifest  error;
                  provided  that  failure to make any such  recordation,  or any
                  error in such  recordation,  shall not affect  any  Borrower's
                  Obligations in respect of the applicable Loans.

                  (iii)  Each  Lender  may  record  on  its   internal   records
                  (including,  without limitation, any promissory note described
                  in  subsection  2.1E)  the  amount of each Loan made by it and
                  each payment in respect thereof; provided that in the event of
                  any  inconsistency  between  the  Register  and  any  Lender's
                  records, the recordations in the Register shall govern, absent
                  manifest error.

                  At the request of Company,  Administrative  Agent will provide
                  to Company not more than once a month, a copy of the Register.

         G.       Stamp Taxes and Other Duties, Expenses.

Company and  Borrowers  shall have no liability  to pay stamp taxes,  duties and
other costs,  taxes,  fees,  charges or other  expenses which may be assessed or
incurred  at the time of, and as a result of, any  assignment  or  participation
made pursuant to this subsection 10.1.

10.2     Expenses.

                  Whether or not the transactions  contemplated  hereby shall be
consummated,  Company and Borrowers  jointly and severally agree to pay promptly
(i) all the actual and reasonable  costs and expenses of preparation of the Loan
Documents;  (ii) all the costs of furnishing all opinions by counsel for Company
or  any  Borrower  (including,   without  limitation,  any  opinions  reasonably
requested by Lenders as to any legal matters arising hereunder) and of

                                      116

confirming compliance with environmental and insurance  requirements;  (iii) the
reasonable fees,  expenses and disbursements of counsel to any Agent or Arranger
in connection with the negotiation, preparation, execution and administration of

Loans and any consents,  amendments,  waivers or other  modifications  hereto or
thereto and any other documents or matters requested by Company or any Borrower;
(iv) all other actual and reasonable costs and expenses incurred by any Agent or
Arranger in connection  with the  negotiation,  preparation and execution of the
Loan Documents and the  transactions  contemplated  hereby and thereby;  and (v)
after the occurrence  and during the  continuation  of an Event of Default,  all
costs and expenses,  including  reasonable  attorneys' fees,  excluding in-house

enforcing any  Obligations  of or in collecting any payments due from Company or
any Borrower hereunder or under the other Loan Documents by reason of such Event
of Default or in connection with any refinancing or  restructuring of the credit
arrangements  provided  under this  Agreement in the nature of a  "work-out"  or
pursuant to any insolvency or bankruptcy proceedings.


10.3     Indemnity.

                  In addition to the payment of expenses  pursuant to subsection
10.2, whether or not the transactions  contemplated hereby shall be consummated,
Company and Borrowers jointly and severally agree to defend,  indemnify, pay and
hold harmless  each Agent,  Arranger and Lenders,  and the officers,  directors,
employees,  counsel,  agents and affiliates of such Agent,  Arranger and Lenders
(collectively  called  the  "Indemnitees")  from and  against  any and all other
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims,  costs,  expenses  and  disbursements  of any kind or nature  whatsoever
(including, without limitation, the reasonable fees and disbursements of counsel
for such  Indemnitees in connection with any  investigative,  administrative  or
judicial  proceeding  commenced or threatened by any Person,  whether or not any
such  Indemnitee  shall be designated as a party or a potential  party thereto),
whether  based  on any  federal,  state  or  foreign  laws,  statutes,  rules or
regulations  (including,  without  limitation,  securities and commercial  laws,
statutes,  rules or  regulations  and  Environmental  Laws),  on  common  law or
equitable  cause or on contract or otherwise,  that may be imposed on,  incurred
by, or  asserted  against  any such  Indemnitee,  in any manner  relating  to or
arising out of this  Agreement or the other Loan  Documents or the  transactions
contemplated  hereby  or  thereby  (including,   without  limitation,   Lenders'
agreement  to make  the  Loans  or  create  and  purchase  Bankers'  Acceptances
hereunder  or the use or  intended  use of the  proceeds  of any of the Loans or
Bankers' Acceptances or the issuance of Letters of Credit hereunder and Lenders'
agreement to purchase  participations therein as provided for herein, or the use
or intended  use of the Letters of Credit) or the  statements  contained  in any
commitment  letter  delivered  by any  Lender to Company  or any  Borrower  with
respect thereto  (collectively called the "Indemnified  Liabilities");  provided
that  neither  Company  nor  any  Borrower  shall  have  any  obligation  to any
Indemnitee  hereunder with respect to any Indemnified  Liabilities to the extent
such  Indemnified  Liabilities  arise  from  the  gross  negligence  or  willful
misconduct  of that  Indemnitee  as finally  determined  by a court of competent
jurisdiction; provided further, that, subject to the hold 


                                      117


harmless  provisions of this subsection 10.3, Company shall be subrogated to all
rights  that any such  Indemnitee  may have in  respect of any person or persons
whose acts or failure  to act  resulted  in the  indemnified  liability  and the
Indemnitee  shall,  upon  receipt of  payment  for all  Indemnified  Liabilities
payable to such  Indemnitee,  assign to Company the rights with  respect to such
Indemnified  Liabilities  such Indemnitee may have against any person or persons
whose acts or failure to act resulted in the indemnified liability; and provided
still further that any exercise of rights of subrogation shall be withheld until
payment of all of the related  Indemnified  Liabilities.  To the extent that the
undertaking  to  defend,  indemnify,  pay and  hold  harmless  set  forth in the
preceding  sentence may be  unenforceable  because it is violative of any law or
public policy,  Company and each Borrower shall  contribute the maximum  portion
that it is permitted to pay and satisfy under  applicable law to the payment and
satisfaction of all Indemnified  Liabilities  incurred by the Indemnitees or any
of them, subject however to the limitations  contained in the last clause of the
preceding sentence.

10.4     Set Off.

                  In  addition  to any rights  now or  hereafter  granted  under
applicable  law  and not by way of  limitation  of any  such  rights,  upon  the
occurrence  of any  Event of  Default  each  Agent  and each  Lender  is  hereby
authorized  by  Company  and each  Borrower  at any  time or from  time to time,
without  notice to Company or such  Borrower  or to any other  Person,  any such
notice being hereby expressly waived, to set off and to appropriate and to apply
any and all  deposits  (general  or  special,  including,  but not  limited  to,
Indebtedness evidenced by certificates of deposit, whether matured or unmatured,
but not including trust accounts) and any other Indebtedness at any time held or
owing by such  Agent or such  Lender  to or for the  credit  or the  account  of
Company  or such  Borrower,  as the case may be,  against  and on account of the
obligations and liabilities then due and payable of Company or such Borrower, as
the case may be, to such  Agent or such  Lender  under this  Agreement,  and any
Notes, any Grid Gold Acknowledgements,  any Letters of Credit and participations
therein, and any Bankers' Acceptances, including, but not limited to, all claims
of any nature or description  arising out of or connected  with this  Agreement,
the  Notes,  the  Grid  Gold   Acknowledgements,   the  Letters  of  Credit  and
participations  therein,  any Bankers'  Acceptances  or any other Loan Document,
irrespective  of whether or not such  Agent or such  Lender  shall have made any
demand hereunder.

10.5     Ratable Sharing.

                  Subject to the provisions of subsection  2.1E,  Lenders hereby
agree among themselves that if any of them shall,  whether by voluntary payment,
by realization  upon  security,  through the exercise of any right of set-off or
banker's  lien, by  counterclaim  or cross action or by the  enforcement  of any
right  under  the  Loan  Documents  or  under  Letters  of  Credit  or  Bankers'
Acceptances or otherwise, or as adequate protection of a deposit treated as cash
collateral  under  the  Bankruptcy  Code,  receive  payment  or  reduction  of a
proportion of the aggregate  amount of  Obligations of any Borrower then due and
owing to that Lender (collectively,  the "Aggregate Amounts Due" to such Lender)
which is greater than the proportion  received by any other Lender in respect of
the Aggregate Amounts Due of such Borrower to such other Lender, then the Lender
receiving such proportionately  greater payment shall (i) notify  Administrative
Agent and each  

                                      118


other  Lender of the  receipt of such  payment  and (ii) apply a portion of such
payment to purchase  participations  (which it shall be deemed to have purchased
from each  seller of a  participation  simultaneously  upon the  receipt by such
seller of its  portion of such  payment)  in the  Aggregate  Amounts Due of such
Borrower to the other Lenders so that all such  recoveries of Aggregate  Amounts
Due shall be shared by all Lenders in proportion to the Aggregate Amounts Due of
such  Borrower  to them;  provided  that if all or part of such  proportionately
greater payment received by such purchasing Lender is thereafter  recovered from
such Lender upon the bankruptcy or  reorganization  of Company,  any Borrower or
otherwise,  those  purchases shall be rescinded and the purchase prices paid for
such  participations  shall be returned to such purchasing Lender ratably to the
extent  of such  recovery,  but  without  interest.  Company  and each  Borrower
expressly consents to the foregoing  arrangement and agrees that any holder of a
participation  so purchased  may  exercise any and all rights of banker's  lien,
set-off or  counterclaim  with respect to any and all monies owing by Company or
such  Borrower to that holder  with  respect  thereto as fully as if that holder
were owed the amount of the participation held by that holder.

10.6     Amendments and Waivers.

                  No  amendment,  modification,  termination  or  waiver  of any
provision  of this  Agreement  or of the Notes or  consent to any  departure  by
Company or any Borrower  therefrom,  shall in any event be effective without the
written   concurrence  of  Requisite  Lenders;   provided  that  any  amendment,

Company or U.S.  Borrower  from its  guaranty  obligations  thereunder;  and the

                                      119


behalf of that  Lender.  Any waiver or consent  shall be  effective  only in the
specific instance and for the specific purpose for which it was given. No notice
to or demand on Company or any Borrower in any case shall entitle Company or any
Borrower  to any  other  or  further  notice  or  demand  in  similar  or  other
circumstances.  Any  amendment,  modification,  termination,  waiver or  consent
effected in  accordance  with this  subsection  10.6 shall be binding  upon each
Lender at the time outstanding,  each future Lender and, if signed by Company or
any Borrower, on Company and such Borrower, as the case may be.

10.7     Increased Costs; Taxes; Capital Adequacy.

                  A.  Compensation  for Increased Costs and Taxes. If any Lender
shall determine (which  determination shall, absent manifest error, be final and
conclusive  and  binding  upon all  parties  hereto)  that any  law,  treaty  or
governmental  rule,  regulation  or  order,  or  any  change  therein  or in the
interpretation,   administration   or   application   thereof   (including   the
introduction of any new law, treaty or governmental rule,  regulation or order),
or any  determination of a court or governmental  authority in each case that is
adopted  after  the  Effective  Date or  compliance  by  such  Lender  with  any
guideline,  request or directive  issued or made after the Effective Date by any
central bank or other governmental or  quasi-governmental  authority (whether or
not having the force of law):

                  (i)  subjects  such  Lender  (or its  Lending  Office)  to any
                  additional Tax (other than any Excluded Taxes) with respect to
                  this  Agreement  or any of the  Loans,  Letters  of Credit (or
                  participations  therein), any risk participations purchased or
                  sold pursuant to subsection  2.1E or Bankers'  Acceptances  or
                  any of its  obligations  hereunder,  or  changes  the basis of
                  taxation of payments to such Lender (or its Lending Office) of
                  any Obligation (except for changes in Excluded Taxes);

                  (ii)  imposes,   modifies  or  holds  applicable  any  reserve
                  (including   without   limitation  any  marginal,   emergency,
                  supplemental,  special  or other  reserve),  special  deposit,
                  compulsory loan, FDIC insurance or similar requirement against
                  assets held by, or deposits or other liabilities in or for the
                  account of, or advances or loans by, or other credit  extended
                  by, or any other  acquisition  of funds by, any office of such
                  Lender (other than any such reserve or other requirements with
                  respect to  Eurodollar  Rate Loans that are  reflected  in the
                  definition of Adjusted Eurodollar Rate); or

                  (iii) imposes any other  condition on or affecting such Lender
                  (or  its  applicable   Lending   Office)  or  its  obligations
                  hereunder  or the London  interbank  market,  precious  metals
                  market,  bankers'  acceptances  market  or bills  of  exchange
                  market;


and the result of any of the foregoing is to increase the cost to such Lender of
agreeing  to  make,  making  or  maintaining   Loans,   Letters  of  Credit  (or
participations  therein)  or  Bankers'  Acceptances  hereunder  or to reduce any
amount  received  or  receivable  by such Lender (or its  Lending  Office)  with
respect thereto;  then, in any such case, Borrowers and Company shall be jointly
and severally  obligated to promptly pay to such Lender, upon written demand and
receipt 

                                      120


of the written  notice  referred  to below,  such  additional  amount or
amounts  (in the  form  of an  increased  rate  of,  or a  different  method  of
calculating,  interest or otherwise as such Lender in its sole discretion  shall
determine) as may be necessary to compensate  such Lender on an after-tax  basis
for any such  increased  cost or  reduction  in amounts  received or  receivable
hereunder.  Such Lender shall deliver to Company and Borrowers a written notice,
setting  forth in reasonable  detail the basis for  calculating  the  additional
amounts owed to such Lender under this subsection  10.7A,  which statement shall
be conclusive and binding upon all parties hereto absent manifest error.

                  Notwithstanding anything contained in this subsection 10.7A or
subsection  10.7B,  if any Lender is unable to make any Loans in the  applicable
currency or in Gold and such inability is not due to circumstances  described in
subsection 2.6A or 2.6B or any other similar circumstances, then any withholding
taxes or any other costs directly resulting from such inability shall be for the
account of such Lender.

         B.       Withholding of Taxes.

                  (i)  Payments  to Be Free  and  Clear.  All  sums  payable  by
                  Borrowers and Company under this  Agreement and the other Loan
                  Documents  to such Lender  shall be paid free and clear of and
                  without any deduction or withholding on account of any Covered
                  Tax  imposed,  levied,  collected,  withheld or assessed by or
                  within the United  States of America,  Australia  or Canada or
                  any  political  subdivision  in or of  the  United  States  of
                  America,  Australia or Canada or any other  jurisdiction  from
                  which a  payment  is made by or on behalf  of  Company  or any
                  Borrower or by any  federation  or  organization  of which the
                  United  States  of  America,  Australia  or Canada or any such
                  jurisdiction is a member at the time of payment.

                  (ii)  Withholding  in respect of  Payments.  If  Company,  any
                  Borrower  or any other  Person is  required by law to make any
                  deduction  or  withholding  on account of any Covered Tax from
                  any sum paid or payable by  Company  or such  Borrower  to any
                  Agent, Arranger or any Lender under any of the Loan Documents:

                          (a) Company and Borrowers shall notify  Administrative
                 Agent  of any  such  requirement  or  any  change  in any  such
                 requirement as soon as Company or any Borrower becomes aware of
                 it;

                          (b)  Company  or such  Borrower,  as the  case may be,
                 shall  pay any  such  Covered  Tax  before  the  date on  which
                 penalties  attach  thereto,  such  payment  to be made  (if the
                 liability  to pay is imposed on Company or such  Borrower)  for
                 its own account or (if that liability is imposed on such Agent,
                 Arranger or such  Lender,  as the case may be) on behalf of and
                 in the name of such Agent, Arranger or such Lender;

                          (c) the sum  payable by Company  or such  Borrower  in
                 respect of which the relevant deduction, withholding or payment
                 is  required  shall be  increased  to the extent  necessary  to
                 ensure that, after the making of that deduction, withholding or


                                      121


                 payment,  such Agent,  Arranger or such Lender, as the case may
                 be,  receives  on the due  date  and  retains  (free  from  any
                 liability  in respect  of any such  deduction,  withholding  or
                 payment) a net sum equal to what it would have  received and so
                 retained  had no such  deduction,  withholding  or  payment  in
                 respect of Covered Taxes been required or made; and

                          (d) within 30 days after  paying any sum from which it
                 is required by law to make any  deduction or  withholding,  and
                 within 30 days  after the due date of  payment of any Tax which
                 it is  required  by  clause  (b)  above  to  pay,  Company  and
                 Borrowers  shall  deliver  to  Administrative   Agent  evidence
                 reasonably  satisfactory to the other affected  parties of such
                 deduction, withholding or payment and of the remittance thereof
                 to the relevant taxing or other authority;

           (iii) U.S. Tax Certificates.  Each Lender that is organized under the
         laws of any  jurisdiction  other than the United States or any state or
         other  political  subdivision  thereof shall deliver to  Administrative
         Agent for transmission to U.S.  Borrower,  on or prior to the Effective
         Date (in the case of each Lender listed on the signature  pages hereof)
         or on the date of the Assignment  and  Acceptance  pursuant to which it
         becomes a Lender (in the case of each other Lender),  and at such other
         times  as may be  necessary  in the  determination  of  Company  or any
         Borrower or  Administrative  Agent (each in the reasonable  exercise of
         its  discretion),  such  certificates,  documents  or  other  evidence,
         properly  and  accurately  completed  and duly  executed by such Lender
         (including,  without limitation,  Internal Revenue Service Form 1001 or
         Form 4224 or any other  certificate or statement of exemption  required
         by Treasury  Regulations  Section 1.1441-4(a) or Section 1.1441-6(c) or
         any successor  thereto) to establish that such Lender is not subject to
         deduction or  withholding  of United  States  federal  income tax under
         Section  1441 or 1442 of the Internal  Revenue  Code or  otherwise  (or
         under any  comparable  provisions  of any  successor  statute) and each
         Lender shall deliver to  Administrative  Agent for  transmission to the
         relevant  Borrower  or  Borrowers  any  such  additional  certificates,
         documents  or  other  evidence  as may at  such  time  be  required  by
         applicable  United States,  Australian or Canadian  federal or state or
         provincial law if required to establish that such Lender is not subject
         to deduction or withholding under United States, Australian or Canadian
         tax laws with  respect to any  payments  to such  Lender of  principal,
         interest,  fees  or  other  amounts  payable  under  any  of  the  Loan
         Documents.  Neither  Company nor any Borrower  shall be required to pay
         any additional amount to any such Lender under clause (c) of subsection
         10.7B(ii) if such Lender shall have failed to satisfy the  requirements
         of the  immediately  preceding  sentence;  provided that if such Lender
         shall have  satisfied  such  requirements  on or prior to the Effective
         Date (in the case of each Lender listed on the signature  pages hereof)
         or on the date of the Assignment  and  Acceptance  pursuant to which it
         became a Lender  (in the case of each  other  Lender),  nothing in this
         subsection  10.7B(iii)  shall  relieve  Company or any  Borrower of any
         obligation  to pay any  additional  amounts  pursuant  to clause (c) of
         subsection  10.7B(ii)  in the event that,  as a result of any change in
         applicable  law after the Effective  Date or the date of the applicable
         Assignment and Acceptance, as the case may be, such Lender is no longer
         properly entitled to deliver certificates,  documents or other evidence
         at a  subsequent  date  establishing  the fact that such  

                                      122



         Lender is not subject to withholding as described in the immediately
         preceding sentence.

                  C.  Capital  Adequacy  Adjustment.  If any  Lender  shall have
determined  in  good  faith  that  the  adoption,  effectiveness,   phase-in  or
applicability (excluding any adoption, effectiveness,  phase-in or applicability
published as of the Effective Date and currently scheduled to take effect) after
the Effective  Date of any law, rule or  regulation  (or any provision  thereof)
regarding  capital adequacy,  or any change therein or in the  interpretation or
administration  thereof after the Effective Date by any governmental  authority,
central  bank  or  comparable   agency  charged  with  the   interpretation   or
administration  thereof,  or compliance by any Lender (or its applicable lending
office) with any  guideline,  request or directive  regarding  capital  adequacy
(whether  or not  having the force of law) of any such  governmental  authority,
central bank or comparable  agency, has or would have the effect of reducing the
rate of return on the capital of such Lender or any corporation controlling such
Lender as a  consequence  of,  or with  reference  to,  such  Lender's  Loans or
Commitment  or  Letters  of  Credit  or   participations   therein  or  Bankers'
Acceptances  or other  obligations  hereunder  to a level  below that which such
Lender  or such  controlling  corporation  could  have  achieved  but  for  such
adoption, effectiveness,  phase-in, applicability,  change or compliance (taking
into  consideration the policies of such Lender or such controlling  corporation
with regard to capital  adequacy),  then from time to time,  within ten Business
Days  after  written  demand  by such  Lender  (with a copy  of such  demand  to
Administrative  Agent),  Company  and  Borrowers  shall pay to such  Lender such
additional  amount or amounts as will compensate such Lender or such controlling
corporation for such reduction.

10.8     Lenders' Obligation to Mitigate; Replacement of Lender.

                  Each Lender agrees that, as promptly as practicable  after the
officer  of such  Lender  responsible  for  administering  the Loans  under this
Agreement  becomes  aware of the  occurrence  of an event or the  existence of a
condition that would cause such Lender to become an Affected  Lender as provided
in subsection  2.6C or that would entitle such Lender to receive  payments under
subsection  10.7A or 10.7C,  it will, to the extent not  inconsistent  with such
Lender's internal policies, use reasonable efforts (i) to make, fund or maintain
the Commitment of such Lender or the affected  Loans or Bankers'  Acceptances of
such Lender through another lending office of such Lender,  or (ii) to take such
other  measures as such Lender may deem  reasonable,  if as a result thereof the
circumstances which would cause such Lender to be an Affected Lender as provided
in subsection  2.6C would cease to exist or the  additional  amounts which would
otherwise be required to be paid to such Lender pursuant to subsection  10.7A or
10.7C would be  materially  reduced and if, as  determined by such Lender in its
sole discretion,  the making, funding or maintaining of such Commitment or Loans
or Bankers'  Acceptances through such other lending office or in accordance with
such other measures,  as the case may be, would not otherwise  adversely  affect
such  Commitment  or Loans or  Bankers'  Acceptances  or the  interests  of such
Lender;  provided  that such Lender will not be  obligated to utilize such other
lending office pursuant to this  subsection  10.8 unless  Borrowers agree to pay
all reasonable  expenses incurred by such Lender in utilizing such other lending
office. A certificate as to the amount of any such expenses payable by Borrowers
pursuant to this subsection  10.8 (setting forth in reasonable  detail 


                                      123



the basis for  requesting  such  amount)  submitted  by such Lender to Borrowers
shall be conclusive absent manifest or demonstrable error.

                  If any  Lender  becomes  entitled  to receive  payments  under
subsection  10.7A or 10.7C,  Borrowers  have the right at any time to treat such
Lender as an Affected  Lender and to substitute  one or more Eligible  Assignees
for such Lender as provided in subsection 2.6C.

10.9     Independence of Covenants.

                  All covenants  hereunder shall be given independent  effect so
that  if a  particular  action  or  condition  is not  permitted  by any of such
covenants,  the fact that it would be  permitted  by an  exception  to, or would
otherwise be within the  limitations  of,  another  covenant shall not avoid the
occurrence  of an Event of Default or Potential  Event of Default if such action
is taken or condition exists.

10.10    Notices.

                  Unless otherwise  specifically  provided herein, any notice or
other communication herein required or permitted to be given shall be in writing
and may be  personally  served,  telecopied,  telexed or sent by United  States,
Australian or Canadian mail or courier  service and shall be deemed to have been
given when delivered in person or by courier  service,  upon receipt of telecopy
or telex if delivered or received on a Business Day or on the first Business Day
after  delivery  or  receipt if  delivered  or  received  on a day that is not a
Business Day. For the purposes hereof, the address of each party hereto shall be
as set forth under such party's name on the signature  pages hereof or (i) as to
Company,  any Borrower,  any Agent and Arranger,  such other address as shall be
designated  by such Person in a written  notice  delivered to the other  parties
hereto  and  (ii) as to each  other  party,  such  other  address  as  shall  be
designated by such party in a written notice delivered to Administrative Agent.

10.11    Survival of Representations, Warranties and Agreements.

                  A. All representations, warranties and agreements made herein,
shall survive the execution  and delivery of this  Agreement,  the making of the
Loans  hereunder,  the  issuance of the Letters of Credit and the  creation  and
purchase of Bankers' Acceptances.

                  B.  Notwithstanding  anything in this  Agreement or implied by
law to the contrary,  the agreements of Company set forth in  subsections  2.6D,
10.2,  10.3, 10.4, 10.7, 10.13 and 10.24 and the agreements of Lenders set forth
in subsections 9.2C, 9.4, 10.4, 10.5,  10.7B(iii),  and 10.24 shall survive, but
this Agreement  shall otherwise  terminate,  upon the termination of the Overall
Commitments,  payment of all Obligations (other than contingent amounts pursuant
to subsections  2.1E,  2.6D, 10.2, 10.3, 10.7 and 10.24 not at such time claimed
or due and payable),  the  cancellation  or expiration of the Letters of Credit,
the cancellation or maturity of all Bankers'  Acceptances and the  reimbursement
of any amounts drawn thereunder;  provided that this Agreement shall continue to
be effective or be  reinstated,  as the case may be, if at any time payment,  or
any part thereof,  of any  Obligation is rescinded or must otherwise be restored
by any 


                                      124


Agent or any Lender  upon the  bankruptcy  or  reorganization  of Company or any
Borrower or otherwise.


10.12    Failure or Indulgence Not Waiver; Remedies Cumulative.

                  No failure or delay on the part of any Lender in the  exercise
of any power,  right or  privilege  hereunder or under a Loan,  Note,  Letter of
Credit or Bankers' Acceptances shall impair such power, right or privilege or be
construed to be a waiver of any default or acquiescence  therein,  nor shall any
single or partial exercise of any such power,  right or privilege preclude other
or further  exercise  thereof or of any other  power,  right or  privilege.  All
rights and remedies  existing under this  Agreement,  the Notes,  the Letters of
Credit, the Bankers' Acceptances and the other Loan Documents are cumulative to,
and not exclusive of, any rights or remedies otherwise available.

10.13    Marshalling; Payments Set Aside.

                  Neither any Agent,  Arranger nor any Lender shall be under any
obligation to marshal any assets in favor of Company,  any Borrower or any other
party or against or in payment of any or all of the  Obligations.  To the extent
that Company or any Borrower makes a payment or payments to any Agent,  Arranger
or Lenders,  or any Agent or Lenders enforce any security  interests or exercise
their  rights of setoff,  and such  payment or payments or the  proceeds of such
enforcement or setoff or any part thereof are subsequently invalidated, declared
to be fraudulent or  preferential,  set aside and/or  required to be repaid to a
trustee,  receiver or any other party under any bankruptcy  law, any other state
or federal law, common law or any equitable  cause,  then, to the extent of such
recovery,  the obligation or part thereof  originally  intended to be satisfied,
and all Liens, rights and remedies therefor or related thereto, shall be revived
and  continued  in full force and effect as if such  payment or payments had not
been made or such enforcement or setoff had not occurred.

10.14    Severability.

                  In case any provision in or obligation  under this  Agreement,
the Notes, the Bankers'  Acceptances or the Grid Gold  Acknowledgments  shall be
invalid,  illegal or unenforceable in any jurisdiction,  the validity,  legality
and  enforceability  of the  remaining  provisions  or  obligations,  or of such
provision  or  obligation  in any  other  jurisdiction,  shall not in any way be
affected or impaired thereby.

10.15    Obligations Several; Independent Nature of Lenders' Rights.

                  The obligations of Lenders hereunder are several and no Lender
shall be  responsible  for the  obligations  or  Commitment  of any other Lender
hereunder. Nothing contained herein or in any other Loan Document, and no action
taken by  Lenders  pursuant  hereto or  thereto,  shall be deemed to  constitute
Lenders as a partnership,  an association,  a joint venture or any other kind of
entity.  The amounts  payable at any time  hereunder  to each Lender  shall be a
separate  and  independent  debt,  and each  Lender  shall  be,  subject  to the
limitations on the right to terminate  Commitments  and accelerate  outstandings
contained in Section 7,  entitled to protect and enforce


                                      125



its rights  arising out of this  Agreement and it shall not be necessary for any
other  Lender to be joined as an  additional  party in any  proceeding  for such
purpose.

10.16    Headings.

                  Section and subsection headings in this Agreement are included
herein for convenience of reference only and shall not constitute a part of this
Agreement for any other purpose or be given any substantive effect.

10.17    Applicable Law.

PARTIES  SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK. EACH LETTER OF CREDIT SHALL BE
GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OR

CUSTOMS")  AND, AS TO MATTERS NOT GOVERNED BY THE UNIFORM  CUSTOMS,  THE LAWS OF
THE STATE OF NEW YORK. EACH BANKERS'  ACCEPTANCE SHALL BE GOVERNED BY, AND SHALL
BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF CANADA.

10.18    Successors and Assigns.

their  respective  successors  and assigns and shall inure to the benefit of the
parties hereto and the  successors and assigns of Agents,  Arranger and Lenders.
The terms and  provisions  of this  Agreement  shall inure to the benefit of any
assignee or transferee of any of the  Obligations,  and in the event of any such
transfer or assignment the rights and privileges  herein  conferred upon Agents,
Arranger  and  Lenders  shall  automatically  extend  to and be  vested  in such
transferee or assignee,  all subject to the terms and conditions hereof. Neither
Company's nor any Borrower's  rights or  obligations  hereunder nor any interest
therein may be  assigned or  delegated  by Company or any  Borrower  without the
prior written consent of all Lenders.  Lenders' rights of assignment are subject
to subsection 10.1.

10.19    Consent to Jurisdiction and Service of Process.

                  ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST ANY PARTY ARISING OUT
OF OR RELATING TO THIS  AGREEMENT OR ANY OTHER LOAN  DOCUMENT OR ANY  OBLIGATION
MAY BE BROUGHT IN ANY STATE OR FEDERAL  COURT OF COMPETENT  JURISDICTION  IN THE
STATE OF NEW YORK,  AND BY EXECUTION AND DELIVERY OF THIS  AGREEMENT  EACH PARTY
ACCEPTS  FOR  ITSELF  AND IN  CONNECTION  WITH  ITS  PROPERTIES,  GENERALLY  AND

                                      126



UNCONDITIONALLY,  THE  NONEXCLUSIVE  JURISDICTION  OF THE  AFORESAID  COURTS AND

Borrower to be effective  and binding  service in every  respect.  A copy of any
such  process  so served  shall be mailed by  registered  mail to Company at its
address as  provided  in  subsection  10.10;  provided  that,  unless  otherwise

courts of any other jurisdiction.

10.20    Waiver of Jury Trial.

                  EACH OF THE PARTIES TO THIS  AGREEMENT  HEREBY AGREES TO WAIVE
ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON
OR  ARISING  OUT OF THIS  AGREEMENT  OR ANY OF THE OTHER LOAN  DOCUMENTS  OR ANY
DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN TRANSACTION OR
THE  LENDER/BORROWER  RELATIONSHIP THAT IS BEING ESTABLISHED.  The scope of this
waiver is intended to be  all-encompassing  of any and all disputes  that may be

claims  and all  other  common  law and  statutory  claims.  Each  party  hereto
acknowledges that this waiver is a material  inducement to enter into a business
relationship,  that each has already relied on this waiver in entering into this
Agreement,  and that each will  continue to rely on this waiver in their related
future  dealings.  Each party hereto further warrants and represents that it has

                                      127


10.21    Confidentiality.

                  Each Lender  shall hold all  non-public  information  obtained
pursuant to the  requirements  of this  Agreement  which has been  identified as
confidential  by  Company  or any  Borrower  in  accordance  with such  Lender's
customary  procedures  for handling  its own  confidential  information  of this
nature  and in  accordance  with  safe and  sound  banking  practices,  it being
understood  and agreed by Company and  Borrowers  that Lenders may disclose such
information (i) to their  accountants and legal counsel in connection with their
ongoing review of the credit  extended under this Agreement and (ii) to any bona
fide or prospective  assignee,  transferee or participant in connection with the
contemplated  assignment  or  transfer  by such  Lender of any  Loans,  Bankers'
Acceptances, participations in Letters of Credit or any participation therein or
as required  (provided  that in each case of disclosure  under (i) and (ii), the
disclosing  party shall  advise  such  persons of the  non-public  nature of the
information  and secure  from such  persons in advance of  disclosure  that such
persons  will treat the  information  as  confidential  in  accordance  with its
customary  procedures  for  handling  confidential  information,  subject to the
disclosure   provisions   herein),   (iii)  to  any   governmental   agency   or
representative  thereof upon its reasonable  request,  or (iv) pursuant to legal
process  (provided  that in the  case of  disclosure  under  (iii)  (other  than
regulatory  reviews in the ordinary course of business) and (iv), the disclosing
party shall  advise  Company  (unless  such  disclosure  is  prohibited  by such
governmental  agency or legal  process) of such  intended  disclosure as soon as
possible in advance if feasible and otherwise as soon as possible thereafter and
shall cooperate with Company,  at Company's expense, in any reasonable effort by
Company to prevent  disclosure of such  information);  provided that in no event
shall any Lender be obligated or required to return any  materials  furnished by
Company or any of its Subsidiaries.

10.22    Entire Agreement.

                  This  Agreement,  taken  together  with all of the other  Loan
Documents  and all  certificates  and other  documents  delivered  by Company to
Administrative Agent and Lenders pursuant to the Loan Documents, and any letters
among Company,  Borrowers,  any Agent and/or Arranger relating to fees, embodies
the entire  agreement and  supersedes  all prior  agreements,  written and oral,
relating to the subject matter hereof.

10.23    Counterparts; Effectiveness.

                  This  Agreement  and  any  amendments,  waivers,  consents  or
supplements  hereto or in  connection  herewith may be executed in any number of
counterparts and by different parties hereto in separate  counterparts,  each of
which when so executed and delivered  shall be deemed an original,  but all such
counterparts  together  shall  constitute  but  one  and  the  same  instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single  counterpart so that all signature pages are physically  attached to
the same document. This Agreement shall become effective upon the execution of a
counterpart  hereof by each of the  parties  hereto and  receipt by Company  and
Administrative Agent of written or telephonic notification of such execution and
authorization of delivery thereof.


                                      128



10.24    Judgment Currency.

                  If for the purposes of obtaining a judgment in any court it is
necessary to convert a sum due hereunder or under any other Loan Document in any
currency (the "Original Currency") into another currency (the "Other Currency"),
the parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be the rate of exchange used in calculating
Dollar Equivalents on the Business Day preceding that on which final judgment is
given.  The obligation of Company and each Borrower in respect of any sum due in
the Original  Currency from it to any Agent or any Lender hereunder or under any
other Loan Document shall,  notwithstanding  any judgment in any Other Currency,
be discharged  only to the extent that on the Business Day following  receipt by
such  Agent  or such  Lender  of any  sum  adjudged  to be so due in such  Other
Currency  such  Agent or such  Lender  may in  accordance  with  normal  banking
procedures  purchase  the Original  Currency  with such Other  Currency;  if the
amount of the Original Currency so purchased is less than the sum originally due
to such Lender in the  Original  Currency,  Company and  Borrowers  agree,  as a
separate  obligation and  notwithstanding  any such judgment,  to indemnify such
Agent or such  Lender  against  such  loss,  and if the  amount of the  Original
Currency  so  purchased  exceeds  the sum  originally  due to any  Lender in the
Original  Currency,  such Agent or such Lender agrees to remit to Company or the
applicable Borrower, as the case may be, such excess.

10.25    Change in Control.

                  A. If  individuals  who on the Effective  Date were members of
the  board of  directors  of  Company  (together  with any new  directors  whose
election to such board of  directors  or whose  nomination  for  election by the
shareholders  of Company was  approved by a vote of a majority of the  directors
then still in office who were either  directors on the  Effective  Date or whose
election or nomination  for election was  previously so approved)  cease for any
reason to constitute a majority of such board of directors then in office; or if
a  "Change  of  Control"  as  defined  in the  indenture  pursuant  to which the
Subordinated  Debentures or pursuant to which the New Subordinated  Indebtedness
will be issued shall have occurred;  or if any Person or any two or more Persons
acting in concert shall have acquired  beneficial  ownership (within the meaning
of Rule 13d-3 of the Securities and Exchange Commission under the Exchange Act),
directly  or  indirectly,   of  Securities  of  Company  (or  other   Securities
convertible  into  such  Securities)  representing  30% or more of the  combined
voting power of all  Securities  of Company  entitled to vote in the election of
directors, there shall be deemed to have occurred a "Company Change of Control."

                  B. If a Change  of  Control  shall  occur,  automatically  and
without any notice to Company and Borrowers,  the Overall  Commitments,  and all
Commitments  and  obligations  of Lenders  hereunder  shall  terminate,  and two
Business Days  thereafter,  all  Obligations  under this Agreement  shall become
payable in full,  including  any amounts that may be due pursuant to  subsection
2.6D.  Failure to pay all  Obligations on the date due and failure to secure the
cancellation of all Letters of Credit and Bankers'  Acceptances then outstanding
shall constitute an Event of Default


                                      129





                  IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  this
Agreement  to be duly  executed  and  delivered  by  their  respective  officers
thereunto duly authorized as of the date first written above.

                                    VII-A-2





Ladies and Gentlemen:

                  We have acted as special New York counsel to Homestake  Mining
Company,  a Delaware  corporation (the  "Company"),  Homestake Mining Company of
California,  a California  corporation (the "U.S.  Borrower"),  Homestake Canada
Inc.,  an Ontario  corporation  (the  "Canadian  Borrower"),  Homestake  Gold of
Australia  Limited,  a  South  Australia  corporation  ("HGAL"),   and  Plutonic
Resources  Limited   ("Plutonic",   and  collectively  with  HGAL,   "Australian
Borrowers")  in  connection  with  the  execution  and  delivery  of the  Credit
Agreement  dated as July , 1998,  among  the  Company,  the U.S.  Borrower,  the
Canadian  Borrower,  the Australian  Borrowers,  the Lenders named therein,  The
Chase  Manhattan  Bank  of  Canada,  as  Canadian  Administrative  Agent,  Chase
Securities  Australia  Limited,  as  Australian   Administrative   Agent,  Chase
Securities  Inc., as Arranger,  and The Chase Manhattan Bank, as  Administrative
Agent (the "Credit Agreement"),  and certain transactions  relating thereto. All
terms used herein that are defined in the Credit  Agreement  have the respective
meanings  specified in the Credit  Agreement.  This letter is being delivered to
you in  satisfaction of the condition set forth in subsection 3.1E of the Credit
Agreement  and with the  understanding  that you are  entering  into the  Credit
Agreement in reliance on the opinions expressed herein.

                  In  our  capacity  as  such  counsel,  we  have  examined  the
originals,  or copies  identified to our  satisfaction as being true copies,  of
such records, documents or other instruments as in our judgment are necessary or
appropriate to enable us to render the opinions  expressed below. These records,
documents and instruments include the following:

                  (a)      The Certificates or Articles of Incorporation of the
                           Company and the U.S. Borrower;

                  (b)      The By-Laws of the Company and the U.S. Borrower;

                  (c)      Certain records of proceedings and actions of the 
                           Board of Directors of the Company and the U.S.
                           Borrower;

                  (d)      The Credit Agreement and the Exhibits and Schedules 
                           annexed thereto;

                  (e)      The Notes and Grid Gold Acknowledgements; and

                  (f)      The forms of Drafts.

                  We have relied with respect to certain factual  matters,  upon
the  certificates  of  certain  officers  of each of the  Company  and the  U.S.
Borrower,  copies of which are being  delivered  to you  herewith,  and upon the
representations and warranties of the Company and the Borrowers contained in the
Credit Agreement.


                                    VII-A-3



                  We have  also  been  furnished  with,  and have  relied  upon,
evidence or advice  satisfactory  to us from the offices of the  Secretaries  of
State of  California  and  Delaware  as  appropriate,  with  respect to the good
standing of the Company or the U.S. Borrower.  In addition, we have obtained and
relied upon such  certificates  and assurances from public  officials as we have
deemed necessary, desirable or appropriate to render the opinions herein.

                  We  have  assumed  the  genuineness  and  authenticity  of all
documents  submitted to us as originals  and the  conformity to originals of all
documents submitted to us as copies,  drafts or forms. In making our examination
of documents executed or to be executed by Persons other than the Company or the
U.S.  Borrower we have assumed that such other  Persons had or have the power to
enter into and perform all obligations  thereunder and have also assumed the due
authorization  by all  requisite  action  and  execution  and  delivery  of such
documents  by such  Persons  and the  validity  and  binding  effect  thereof in
relation to such Persons.

                  We have  investigated such questions of law for the purpose of
rendering  this  opinion  as  we  have  deemed  necessary,   including,  without
limitation,  Regulations  G, T, U and X of the Board of Governors of the Federal
Reserve  System.  We  are  opining  herein  as to  the  effect  on  the  subject
transaction  of only the  federal  laws of the  United  States,  the laws of the
States of New York and California and the general  corporate law of the State of
Delaware.

                  On the basis of the foregoing,  and in reliance  thereon,  and
subject to the  limitations,  qualifications  and exceptions set forth below, we
are of the opinion that:

                  1. Each of the Company and the U.S.  Borrower is a corporation
duly  incorporated,  validly existing and in good standing under the laws of its
jurisdiction  of  incorporation  and  has  all  requisite  corporate  power  and
authority to own and operate its properties and to execute,  deliver and perform
the Credit  Agreement and, in the case of the U.S.  Borrower,  the Notes and the
Grid  Gold  Acknowledgements  and to  carry  out the  transactions  contemplated
thereby.

                  2. The  execution,  delivery  and  performance  of the  Credit
Agreement by each of the Company and the U.S. Borrower have been duly authorized
by all necessary  corporate  action on the part of the Company or such Borrower,
as the case may be. The issuance of the Notes and the Grid Gold Acknowledgements
by the U.S. Borrower has been duly authorized by all necessary  corporate action
on the part of such Borrower.

                  3.  Assuming  the due  execution  and  delivery  of the Credit
Agreement by the Company and each Borrower, the Credit Agreement constitutes the
legally  valid  and  binding   obligation  of  the  Company  and  each  Borrower
enforceable  against the Company and each Borrower in accordance with its terms.
Assuming the due issuance of the Notes, Grid Gold  Acknowledgements and Bankers'
Acceptances by each Borrower,  each of the Notes, Grid Gold Acknowledgements and
Bankers' Acceptances constitutes the legally valid and binding obligation of the
Borrower issuing the same  enforceable  against such Borrower in accordance with
its terms.



                                    VII-A-4



                  4. It is not  necessary in  connection  with the execution and
delivery of the Credit Agreement by the Company or the Borrowers or the issuance
of the  Notes,  Grid  Gold  Acknowledgements  and  Bankers'  Acceptances  by the
Borrowers  to  register  the  Credit   Agreement,   the  Notes,  the  Grid  Gold
Acknowledgements or the Bankers' Acceptances under the Securities Act of 1933 or
to qualify an indenture in respect of the Notes under the Trust Indenture Act of
1939, as amended.

                  5. None of the execution and delivery of the Credit  Agreement
by the  Company  and  the  Borrowers,  the  issuance  of the  Notes,  Grid  Gold
Acknowledgements or Bankers'  Acceptances by the Borrowers,  the consummation of
the transactions  contemplated by the Credit  Agreement,  or the compliance with
the terms and conditions  thereof by the Company or the  Borrowers,  as the case
may be, conflicts with,  results in a breach or a violation of, or constitutes a
default under, any of the terms, conditions or provisions of (y) the Certificate
or Articles of Incorporation or By-Laws of the Company or the U.S. Borrower,  or
(z) any present  United States  federal or New York statute,  rule or regulation
that is binding on the Company or any Borrower.

                  6.  No  governmental   consents,   approvals,   registrations,
declarations  or filings  are  required to be obtained or made by the Company or
any  Borrower  in  connection  with the  execution  and  delivery  of the Credit
Agreement   or,  in  the  case  of  the   Borrowers,   the   Notes,   Grid  Gold
Acknowledgements or Bankers' Acceptances except as have already been obtained.

                  7. The making of the Loans and the application of the proceeds
thereof as provided in the Credit  Agreement  do not violate or require  filings
under  Regulation G, T, U or X of the Board of Governors of the Federal  Reserve
System.

                  8. All  Obligations of Company under the Credit  Agreement are
within the  definition of "Senior  Debt" in the indenture  pursuant to which the
Subordinated Debentures have been issued.

                  Our opinion as to enforceability of the Credit Agreement,  the
Notes, Grid Gold  Acknowledgements  and Bankers' Acceptances is qualified by and
subject to:

                  (a)   limitations    imposed   by   bankruptcy,    insolvency,
                  reorganization,  moratorium  or similar  laws  relating  to or
                  affecting the enforcement of creditors' rights generally,  and
                  laws   relating  to  fraudulent   transfers  or   conveyances,
                  preferences and equitable subordination;

                  (b)   general   principles   of  equity,   including   without
                  limitation,  concepts  of  materiality,  reasonableness,  good
                  faith and fair  dealing  and the  possible  unavailability  of
                  specific  performance  or  injunctive  relief  (regardless  of
                  whether such  enforceability  is considered in a proceeding in
                  equity or at law);

                  (c) the qualification that certain remedial  provisions of the
                  Credit Agreement may be unenforceable in whole or in part, but
                  such document


                                    VII-A-5



                  contains adequate provisions for practical realization of the 
                  benefits purported to be created thereby;

                  (d)  the  unenforceability   under  certain  circumstances  of
                  provisions  purporting  to release or exculpate any party from
                  liability for its acts or omissions, or purporting to impose a
                  duty upon any party to  indemnify  any  other  party  when any
                  claimed  damages  result from the gross  negligence or willful
                  misconduct of the party seeking such indemnity;

                  (e)  the  unenforceability   under  certain  circumstances  of
                  waivers,  and provisions  imposing  liquidated  damages,  late
                  payment charges or forfeitures, if such amounts are determined
                  to be penalties in light of the actual damages incurred;

                  (f) the  qualification  that any money judgment  rendered by a
                  court in the State of New York or  California  will be payable
                  in United States dollars.

                  This opinion is being delivered upon the express  instructions
of each of the Company and the  Borrowers  to the Agents,  the  Arranger and the
Lenders and their permitted  assignees and  participants and is solely for their
benefit in  connection  with the above  transactions.  This  opinion  may not be
relied upon for any other purpose,  or relied upon by any other person,  firm or
corporation  for any  purpose,  without  our prior  written  consent;  provided,
however,  that each of the  Agents,  the  Arranger  and the  Lenders,  and their
permitted  assigns  and  participants,  may  provide  this  opinion  (i) to bank
examiners  and  other  regulatory  authorities  should  they  so  request  or in
connection with their normal  examinations,  (ii) to its respective  independent
auditors and attorneys, (iii) pursuant to order or legal process of any court or
governmental  agency,  (iv) in connection with any action to which it is a party
arising out of the transactions  contemplated by the Credit Agreement, or (v) to
prospective  assignees of, or participants  in, all or any portion of its Loans,
Bankers' Acceptances,  participations in Letters of Credit or Overall Commitment
under the Credit Agreement.


Very truly yours,

I have  personally  supervised  the actions of the Company and the  Borrowers in

listings certified by the Persons executing such Opinion  Certificates to be all
of the  indentures,  mortgages,  deeds of trust,  material  pledge and  security
agreements,  bank loans,  credit  agreements  and other  material  evidences  of
indebtedness of the Company, the U.S. Borrower, the Canadian Borrower, HGAL, and
Plutonic  (collectively,  the "Debt  Agreements") and listings  certified by the
Persons executing such Opinion Certificates to be all of the other agreements by
which the Company, the U.S. Borrower,  the Canadian Borrower,  HGAL, or Plutonic
is or will be, after the execution of the documents  referred to herein, a party
or by which the Company,  the U.S.  Borrower,  the Canadian  Borrower,  HGAL, or
Plutonic or any of their  respective  properties are bound or affected and which
are  certified to be material to the  business,  operations or properties of the
Company,  the  U.S.  Borrower,   the  Canadian  Borrower  ,  HGAL,  or  Plutonic
(collectively,  the "Material Agreements"). I have no reason to believe that the
Agents,  the  Arranger or the  Lenders  and I are not  entitled to rely upon the
certificates and the representations and warranties referred to above.

                  I have  also  been  furnished  with,  and  have  relied  upon,
evidence or advice  satisfactory  to me from the offices of the  Secretaries  of
State of  California  and Delaware  and the Ministry of Consumer and  Commercial
Relations of Ontario, [need entity for Australian certification] as appropriate,
with respect to the good standing or corporate  status of the Company,  the U.S.
Borrower,  the Canadian  Borrower,  HGAL,  and  Plutonic.  In  addition,  I have
obtained  and relied upon such other  certificates  and  assurances  from public
officials as I have deemed  necessary,  desirable or  appropriate  to render the
opinions herein, copies of which have been delivered to Administrative Agent.

                  I  have  assumed  the  genuineness  and  authenticity  of  all
documents  submitted to me as originals  and the  conformity to originals of all
documents  submitted to me as copies,  drafts or forms. In making my examination
of documents  executed or to be executed by Persons other than the Company,  the
U.S. Borrower, the Canadian Borrower or the Australian Borrowers, I have assumed
that such  other  Persons  had or have the power to enter into and  perform  all
obligations  thereunder  and have  also  assumed  the due  authorization  by all
requisite  action and execution  and delivery of such  documents by such Persons
and the validity and binding effect thereof in relation to such Persons.

                  I have  investigated  such questions of law for the purpose of
rendering  this  opinion  as  I  have  deemed  necessary,   including,   without
limitation,  Regulations  G, T, U and X of the Board of Governors of the Federal
Reserve System. I am opining herein as to the effect on the subject  transaction
of the federal laws of the United  States,  the laws of the State of  California
and, in respect  only of the general  corporation  law, the laws of the State of
Delaware.


                                    VII-B-3



                  On the basis of the foregoing,  and in reliance  thereon,  and
subject to the limitations,  qualifications and exceptions set forth below, I am
of the opinion that:

                  1. Each of the Company and the Borrowers is a corporation duly
incorporated,  validly  existing  and in good  standing  under  the  laws of its
jurisdiction  of  incorporation  and  has  all  requisite  corporate  power  and
authority to own and operate its  properties and to carry on its business as now
conducted, to execute, deliver and perform the Credit Agreement and, in the case
of the Borrowers,  the Notes,  the Grid Gold  Acknowledgements  and the Bankers'
Acceptances, and to carry out the transactions contemplated thereby.

                  2. Each of the  Company  and the  Borrowers  has not failed to
qualify to do business as a foreign  corporation  in any state or province where
the  consequence  of failure to be so  qualified  would have a material  adverse
effect on the Company's or any Borrower's business, operations or properties.

                  3. The  execution,  delivery  and  performance  of the  Credit
Agreement by each of the Company and the Borrowers have been duly  authorized by
all necessary corporate action on the part of the Company and the Borrowers. The
issuance  of  the  Notes,  the  Grid  Gold  Acknowledgements  and  the  Bankers'
Acceptances by each Borrower has been duly authorized by all necessary corporate
action on the part of such Borrower.

                  4. The Credit  Agreement  has been duly executed and delivered
by the Company and each Borrower.  The Notes and Grid Gold Acknowledgements have
been duly issued by the Borrowers.

                  5. It is not  necessary in  connection  with the execution and
delivery of the Credit Agreement by the Company or the Borrowers or the issuance
of the Notes, the Grid Gold Acknowledgements and the Bankers' Acceptances by the
Borrowers  to  register  the  Credit   Agreement,   the  Notes,  the  Grid  Gold
Acknowledgements or the Bankers' Acceptances under the Securities Act of 1933 or
to qualify an indenture in respect of the Notes under the Trust Indenture Act of
1939, as amended.

                  6. None of the execution and delivery of the Credit  Agreement
by the  Company  and  the  Borrowers,  the  issuance  of the  Notes,  Grid  Gold
Acknowledgements and Bankers' Acceptances by the Borrowers,  the consummation of
the transactions  contemplated by the Credit  Agreement,  or the compliance with
the terms and conditions  thereof by the Company or the  Borrowers,  as the case
may  be,  (A)  conflicts  with,  results  in a  breach  or a  violation  of,  or
constitutes a default under,  any of the terms,  conditions or provisions of (w)
the Certificate or Articles of Incorporation, Articles of Association or By-Laws
of the Company or the Borrowers,  (x) any Debt Agreement or Material  Agreement,
(y) any order, writ,  judgment or decree to which, to my knowledge,  the Company
or any Borrower is a party or by which, to my knowledge, any of their respective
properties  or assets  are bound and which is  material  to the  Company  or any
Borrower,  or (z) any present United States federal or California statute,  rule
or regulation that is binding on the Company or any Borrower, or


                                    VII-B-4



(B) results in the creation of any Lien upon any of the  properties or assets of
the Company or any Borrower under any agreement referred to in clause (x) above.

                  7. To my  knowledge,  there is no action,  suit or  proceeding
pending or threatened against or affecting the Company or any Borrower at law or
in equity before any court,  arbitrator or  administrative  or governmental body
(a) in which an order has been entered preventing the making of any of the Loans
or other  extensions  of credit under the Credit  Agreement,  or (b) that could,
either  individually or in the aggregate,  have a material adverse effect on the
ability of the  Company or any  Borrower to perform  its  obligations  under the
Credit  Agreement  or, in the case of any  Borrower,  the  Notes,  the Grid Gold
Acknowledgements  or the  Bankers'  Acceptances  to  which  it is a party or the
financial  condition of the Company and its  Subsidiaries,  taken as a whole, or
any Borrower.

                  8.  Neither  the Company  nor any  Borrower is an  "investment
company" or a company  "controlled" by an "investment company" as such terms are
defined  in the  Investment  Company  Act of 1940,  as  amended,  or  subject to
regulation under the Public Utility Holding Company Act of 1935, as amended, the
Federal Power Act, as amended,  the Interstate  Commerce Act, as amended, or any
federal  or  state  statute  or   regulation   limiting  its  ability  to  incur
Indebtedness  with  respect to money  borrowed or to create  Liens on any of its
properties or assets to secure such Indebtedness.

                  9.  No  United  States  federal  or  California   governmental
consents, approvals,  registrations,  declarations or filings are required to be
obtained or made by the Company or any Borrower in connection with the execution
and  delivery  of the Credit  Agreement  or, in the case of the  Borrowers,  the
Notes, Grid Gold Acknowledgements or Bankers' Acceptances except as have already
been obtained.

                  10.  The  making  of the  Loans  and  the  application  of the
proceeds  thereof as provided in the Credit  Agreement do not violate or require
filings  under  Regulation G, T, U or X of the Board of Governors of the Federal
Reserve System.

                  11. All Obligations of Company under the Credit  Agreement are
within the  definition of "Senior  Debt" in the indenture  pursuant to which the
Subordinated Debentures have been issued.

                  This opinion is being delivered upon the express  instructions
of each of the Company and the  Borrowers  to the Agents,  the  Arranger and the
Lenders, and their permitted assignees and participants, and is solely for their
benefit in  connection  with the above  transactions.  This  opinion  may not be
relied upon for any other purpose,  or relied upon by any other person,  firm or
corporation for any purpose, without prior written consent;  provided,  however,
that each of the Agents,  the  Arranger  and the  Lenders,  and their  permitted
assignees and  participants,  may provide this opinion (i) to bank examiners and
other regulatory  authorities should they so request or in connection with their
normal examinations,  (ii) to its respective independent auditors and attorneys,
(iii)  pursuant to order or legal process of any court or  governmental  agency,
(iv) in  connection  with any action to which it is a party  arising  out of the
transactions contemplated by the Credit Agreement, or (v) to prospective



                                    VII-B-5



assignees  of, or  participants  in, all or any  portion of its Loans,  Bankers'
Acceptances, participations in Letters of Credit or Overall Commitment under the
Credit Agreement.


Very truly yours,

                                    VIII-A-1



Dear Sirs/Mesdames:

                  We have acted as  Canadian  counsel to  Homestake  Canada Inc.
(the "Canadian  Borrower") in connection  with the execution and delivery of the
above-noted  Credit Agreement and certain  transactions  relating  thereto.  All
terms used herein that are defined in the Credit  Agreement  have the respective
meanings  specified in the Credit  Agreement.  This letter is being delivered to
you in  satisfaction of the condition set forth in subsection 3.1E of the Credit
Agreement  and with the  understanding  that you are  entering  into the  Credit
Agreement in reliance on the opinions expressed herein.

                  In  our  capacity  as  such  counsel,  we  have  examined  the
originals,  or copies  identified to our  satisfaction as being true copies,  of
such records, documents or other instruments as in our judgment are necessary or
appropriate to enable us to render the opinions  expressed below. These records,
documents and instruments include the following:

                  (a)   The Re-stated  Articles of Incorporation  and amendments
                        thereto (collectively,  the "Articles of Incorporation")
                        of the Canadian Borrower;

                  (b)   The By-Laws of the Canadian Borrower;

                  (c)   Certain  records of proceedings and actions of the Board
                        of Directors of the Canadian Borrower;

                  (d)   The Credit  Agreement  and the  Exhibits  and  Schedules
                        annexed thereto;

                  (e)   The Notes and Grid Gold Acknowledgements; and

                  (f)   The form of Drafts.

                  We  have  been  furnished   with,  and  have  relied  upon,  a
certificate of incumbency of the Canadian  Borrower  setting forth the directors
and  officers  of  the  Canadian   Borrower  and  certain  of  their  respective
signatures.

                  We have also been furnished  with, and have relied upon,  such
certificates  from public  officials as we have deemed  necessary,  desirable or
appropriate to render the opinions herein.

                  We  have  assumed  the  genuineness  and  authenticity  of all
documents  submitted to us as originals  and the  conformity to originals of all
documents submitted to us as copies,  drafts or forms. In making our examination
of  documents  executed  or to be executed  by Persons  other than the  Canadian
Borrower we have assumed that such other  Persons had or have the power to enter
into and perform all their respective  obligations thereunder (including without
limitation the legal capacity of all such Persons who are  individuals) and have
also assumed the due  authorization  by all  requisite  action and execution and
delivery of such  documents by such Persons and the validity and binding  effect
thereof in relation to such Persons.


                                    VIII-A-2



                  We have  investigated such questions of law for the purpose of
rendering this opinion as we have deemed necessary.  We are solicitors qualified
to carry on the  practice  of law in the  Province  of Ontario and we express no
opinion as to any laws, or any matters governed by any laws, other than the laws
of the  Province  of Ontario and the federal  laws of Canada  applicable  in the
Province of Ontario.

                  On  the   basis  of  the   foregoing   and   subject   to  the
qualifications set forth below, we are of the opinion that:

                  1. The Canadian  Borrower is a corporation  duly  incorporated
and validly  existing  under the laws of the Province of Ontario and has all the
powers of a natural person including all requisite corporate power and authority
(i) to own and lease its properties and assets; (ii) to carry on its business as
presently  conducted;  and (iii) to  execute,  deliver  and  perform  the Credit
Agreement, the Notes issued by the Canadian Borrower (the "Canadian Notes"), the
Grid Gold  Acknowledgements  issued by the Canadian Borrower (the "Canadian Grid
Gold  Acknowledgements")  and all Bankers'  Acceptances  sold by it from time to
time and to carry out the transactions contemplated thereby.

                  2. The Canadian Borrower is registered as an  extra-provincial
corporation in the Province of British Columbia.

                  3. The  execution,  delivery  and  performance  of the  Credit
Agreement  and the  issuance  of the  Canadian  Notes,  the  Canadian  Grid Gold
Acknowledgements  and from time to time  Banker's  Acceptances  by the  Canadian
Borrower have been duly authorized by all necessary corporate action on the part
of the Canadian Borrower,  and the Credit Agreement,  the Canadian Notes and the
Canadian Grid Gold Acknowledgements have been duly executed and delivered by the
Canadian Borrower.

                  4. (a) The choice of the law of the State of New York, without
giving  effect to the conflicts of laws rules  thereof,  as the governing law of
the  Credit   Agreement,   the   Canadian   Notes,   the   Canadian   Grid  Gold
Acknowledgements and the Bankers' Acceptances is a valid and effective choice of
law under the laws of the Province of Ontario.

                           (b)  In proceedings brought before a court of 
competent  jurisdiction in the Province of Ontario, the laws of the State of New
York would,  to the extent  specifically  pleaded and proved with respect to the
Credit Agreement, the Canadian Notes, the Canadian Grid Gold Acknowledgements or
the Bankers' Acceptances as a fact by expert evidence, be recognized and applied
by such court to all issues which are to be determined  in accordance  with such
laws, except that in any such proceedings,  such court (i) will apply those laws
of the Province of Ontario which it  characterizes  as  procedural  and will not
apply  those  laws of the  State  of New  York as such  court  characterizes  as
procedural;  and (ii) will not apply those laws of the State of New York which a
court of the Province of Ontario would  characterize as revenue,  expropriatory,
penal or similar laws or the  application  of which would be  inconsistent  with
public policy, as such term is applied by such court.

                                    VIII-A-3



                           (c)  No provision of the Credit Agreement, the
Canadian  Notes,  the  Canadian  Grid  Gold  Acknowledgements  or  the  Bankers'
Acceptances is inconsistent  with public policy,  as such term is applied by the
courts of the Province of Ontario.

                           (d) The  submission  in the Credit  Agreement  by the
Canadian Borrower to the
non-exclusive jurisdiction of the courts of the State of New York is binding and
enforceable against the Canadian Borrower.

                  5. None of the execution and delivery of the Credit  Agreement
by the Canadian Borrower,  the issuance of the Canadian Notes, the Canadian Grid
Gold Acknowledgements and the Bankers' Acceptances by the Canadian Borrower, the
consummation of the transactions  contemplated by the Credit  Agreement,  or the
compliance  with the terms  and  conditions  thereof  by the  Canadian  Borrower
conflicts with,  results in a breach or a violation of, or constitutes a default
under,  any  of  the  terms,   conditions  or  provisions  of  the  Articles  of
Incorporation  or By-Laws of the  Canadian  Borrower,  or any  statute,  rule or
regulation  of the  Province  of Ontario  or the  federal  government  of Canada
applicable therein that is binding on the Canadian Borrower.

                  6. We have not  been  retained  by the  Canadian  Borrower  in
connection with any action,  suit or proceeding pending or presently  threatened
against or affecting the Canadian Borrower at law or in equity before any court,
arbitrator or administrative or governmental body.

                  7. No consent, approval,  registration,  declaration or filing
of the  Province  of  Ontario or the  federal  government  of Canada  applicable
therein  are  required  to be  obtained  or made  by the  Canadian  Borrower  in
connection with the execution, delivery and performance by the Canadian Borrower
or the enforceability against the Canadian Borrower of the Credit Agreement, the
Notes, the Grid Gold Acknowledgements or the Bankers' Acceptances.

                  8. In any  bankruptcy  proceeding  under  the  Bankruptcy  and
Insolvency  Act (Canada),  the  obligation  of payment of the Canadian  Borrower
under  the  Credit  Agreement,  the  Canadian  Notes,  the  Canadian  Grid  Gold
Acknowledgement and the outstanding Bankers' Acceptances will rank at least pari
passu with the claims of all other creditors of the Canadian  Borrower which are
not secured or preferred  creditors of the Canadian  Borrower within the meaning
of that statute or which are not otherwise entitled to priority by statute.

                  9. The  Canadian  Borrower is not  entitled to claim  immunity
from legal process of the  enforcement  of any judgement of a court of competent
jurisdiction, whether generally or in relation to any specific assets.

                  10. A final and conclusive  judgement in personam granted by a
court of competent  jurisdiction  in the State of New York may be enforced in an
Ontario  court by an action  or  counterclaim  for the  amount  due  under  such
judgement, provided that:



                                    VIII-A-4



         (a)      the  judgement  was obtained  after proper  service of process
                  under New York law in connection  with the action in which the
                  jurisdiction was obtained;

         (b)      the New York court acted within its jurisdiction under New 
                  York law;

         (c)      the  judgement  is  final  and  conclusive,  and  no  stay  of
                  execution has been ordered by the New York law;

         (d)      the  judgement  is not  impeachable  as  void or  voidable  or
                  otherwise ineffective under New York law;

         (e)      the judgement was not obtained by fraud or any manner contrary
                  to the  rules  of  natural  justice,  the  judgement  and  the
                  enforcement  thereof are not  inconsistent  with public policy
                  (as such term is applied by the Ontario court);

         (f)      the  judgement  is for a fixed sum of money which is not to be
                  determined  at a  future  time,  and  the  enforcement  of the
                  judgement  in the  Province  of Ontario  does not  constitute,
                  directly or indirectly,  the enforcement of laws characterized
                  by  the   applicable   Ontario  court  as  being  of  revenue,
                  expropriatory, penal, or public law nature;

         (g)      no new  admissible  evidence  relevant to the action which was
                  the subject  matter of the  judgement is  discovered or arises
                  prior  to the  enforcement  of the  judgement  by the  Ontario
                  court;

         (h)      the action to enforce the  judgment is  commenced  against the
                  judgement  debtor in the Ontario  court within the  applicable
                  limitation period; and

         (i)    the Ontario court may give judgement in Canadian currency only.

                  This opinion is being delivered upon the express  instructions
of the  Canadian  Borrower  to the  Agents,  Arranger  and the Lenders and their
permitted  assignees  and  participants  and is  solely  for  their  benefit  in
connection with the above transactions.  This opinion may not be relied upon for
any other purpose,  or relied upon by any other person,  firm or corporation for
any purpose, without our prior written consent; provided,  however, that each of
the  Agents,  Arranger  and  the  Lenders  and  their  permitted  assignees  and
participants may provide this opinion (i) to bank examiners and other regulatory
authorities   should  they  so  request  or  in  connection  with  their  normal
examinations,  (ii) to its respective independent auditors and attorneys,  (iii)
pursuant to order or legal process of any court or governmental  agency or other
binding statutory requirement, (iv) in connection with any action to which it is
a party arising out of the transactions contemplated by the Credit Agreement, or
(v) to prospective assignees of, or participants in, all or any portion of its


                                    VIII-A-5



Loans,  Bankers'  Acceptances,  participations  in  Letters or Credit or Overall
Commitment under the Credit Agreement.


Yours very truly,

Ladies and Gentlemen:

                  We have  acted as  Australian  counsel  to  Homestake  Gold of
Australia  Limited  ("HGAL") and Plutonic  Resources  Limited  ("Plutonic";  and
collectively with HGAL, "Australian Borrowers") in connection with the execution
and  delivery of the  above-noted  Credit  Agreement  and  certain  transactions
relating thereto. All terms used herein that are defined in the Credit Agreement
have the respective  meanings specified in the Credit Agreement.  This letter is
being  delivered to you in satisfaction of the condition set forth in subsection
3.1E of the Credit  Agreement and with the  understanding  that you are entering
into the Credit Agreement in reliance on the opinions expressed herein.

                  In  our  capacity  as  such  counsel,  we  have  examined  the
originals,  or copies  identified to our  satisfaction as being true copies,  of
such records, documents or other instruments as in our judgment are necessary or
appropriate to enable us to render the opinions  expressed below. These records,
documents and instruments include the following:

                  (a)   The  Certificates  of  Incorporation  of the  Australian
                        Borrowers;


                  (b)   The  Memoranda  and  Articles  of   Association  of  the
                        Australian Borrowers;

                  (c)   Certain  records of proceedings and actions of the Board
                        of Directors of the Australian Borrowers;

                  (d)   The Credit  Agreement  and the  Exhibits  and  Schedules
                        annexed thereto; and

                  (e)   The Notes and Grid Gold Acknowledgements.

                  We  have  been   furnished   with,   and  have  relied   upon,
certificates  of  incumbency  of the  Australian  Borrowers  setting  forth  the
directors and officers of the Australian  Borrowers authorized to sign documents
in connection with the Credit Agreement and their respective signatures.

                  We have conducted a search of the Australian  Borrowers at the
Australian  Securities Commission on [insert date] and relied on the correctness
of the results of that search.

                  We  have  assumed  the  genuineness  and  authenticity  of all
documents  submitted to us as originals  and the  conformity to originals of all
documents submitted to us as copies,  drafts or forms. In making our examination
of  documents  executed or to be executed by Persons  other than the  Australian
Borrowers we have assumed that such other Persons had or have the power to enter
into and perform all obligations  thereunder  (including  without limitation the
legal  capacity of all such Persons who are  individuals)  and have also assumed
the due authorization by all requisite action and execution and delivery of such
documents  by such  Persons  and the  validity  and  binding  effect  thereof in
relation to such Persons.


                                    VIII-B-2



                  We have  investigated such questions of law for the purpose of
rendering  this  opinion  as we  have  deemed  necessary.  We  are  [solicitors]
qualified to carry on the practice of law in the  Commonwealth  of Australia and
we express no opinion as to any laws, or any matters governed by any laws, other
than the laws of the Commonwealth of Australia and its States and Territories.

                  On the basis of the foregoing,  and in reliance  thereon,  and
subject to the  limitations,  qualifications  and exceptions set forth below, we
are of the opinion that:

                  1. The Australian Borrowers are corporations duly incorporated
and validly  existing  under the laws of the  Commonwealth  of Australia and its
States and Territories and has all the powers of a natural person  including all
requisite  corporate  power and authority (i) to own and lease their  properties
and assets;  (ii) to carry on its  business;  and (iii) to execute,  deliver and
perform the Credit Agreement,  the Notes and the Grid Gold  Acknowledgements and
to carry out the transactions contemplated thereby.

                  2. The  execution,  delivery  and  performance  of the  Credit
Agreement  and the issuance of the Notes and the Grid Gold  Acknowledgements  by
the Australian  Borrowers have been duly  authorized by all necessary  corporate
action on the part of the Australian Borrowers and have been validly executed by
the Australian Borrowers.

                  3.  The  Credit  Agreement,   the  Notes  and  the  Grid  Gold
Acknowledgements   constitute   valid  and  legally   binding  and   enforceable
obligations  of the  Australian  Borrowers in accordance  with their  respective
terms.


                  4. (a) The choice of the law of the State of New York, without
giving  effect to the conflicts of laws rules  thereof,  as the governing law of
the Credit Agreement,  the Notes and the Grid Gold  Acknowledgements  is a valid
and effective  choice of law under the laws of the Commonwealth of Australia and
its States and Territories.


                     (b)      In  proceedings  brought  before a court of 
competent  jurisdiction in the Commonwealth of Australia,  the laws of the State
of New York would,  to the extent  specifically  pleaded and proved as a fact by
expert  evidence,  be recognized  and applied by such court to all issues which,
under the conflicts of laws rules of the  Commonwealth  of Australia,  are to be
determined  in accordance  with the proper or governing law of contract,  except
that in any such  proceedings,  [such  court (i) will  apply  those  laws of the
Commonwealth  of Australia  which it  characterizes  as procedural  and will not
apply  those  laws of the  State  of New  York as such  court  characterizes  as
procedural;  (ii) will not  apply  those  laws of the State of New York  which a
court  of  the   Commonwealth  of  Australia  would   characterize  as  revenue,
expropriatory,  penal or  similar  laws or the  application  of  which  would be
inconsistent  with public  policy,  as such term is applied by such  court;  and
(iii) may only give judgment in Australian dollars.]



                                    VIII-B-3




                    (c)  No  provision  of  the  Credit  Agreement,  the  Notes
or the Grid Gold  Acknowledgements  is inconsistent  with public policy, as such
term is applied by the courts of the Commonwealth of Australia.


                    (d) The submission in the Credit Agreement by the Australian
Borrowers to the  non-exclusive  jurisdiction  of the courts of the State of New
York is legal, valid and binding.

                  5. None of the execution and delivery of the Credit  Agreement
by the  Australian  Borrowers,  the  issuance  of the  Notes  and the Grid  Gold
Acknowledgements   by  the  Australian   Borrowers,   the  consummation  of  the
transactions  contemplated by the Credit  Agreement,  or the compliance with the
terms and conditions thereof by the Australian Borrowers conflicts with, results
in a breach or a violation of, or constitutes a default under, any of the terms,
conditions or provisions  of the  Memoranda and Articles of  Association  of the
Australian Borrowers,  or any statute, rule or regulation of the Commonwealth of
Australia  and its States  and  Territories  that is  binding on the  Australian
Borrower.

                  6. We have not been  retained by the  Australian  Borrowers in
connection with any action,  suit or proceeding pending or threatened against or
affecting  the  Australian  Borrowers  at law or in  equity  before  any  court,
arbitrator or administrative or governmental body.

                  7. No federal  Australian  governmental  consents,  approvals,
registrations,  declarations  or filings are  required to be obtained or made by
the  Australian  Borrowers  in  connection  with  the  execution,   delivery  or
performance of the Australian Borrowers' obligations under the Credit Agreement,
the Notes or the Grid Gold  Acknowledgements  in order to ensure  the  legality,
enforceability or admissibility of the documents or for any reason whatsoever.

                  8. No ad valorem stamp duty or similar documentary tax or duty
in or of any  State  or  Territory  of the  Commonwealth  of  Australia  will be
applicable  with respect to the execution and delivery of the Credit  Agreement,
the  Notes  or  the  Grid  Gold  Acknowledgements  and  the  performance  by the
Australian Borrowers of its obligations under those documents.

                  9. The monetary  obligations of the Australian Borrowers under
the Credit  Agreement,  the Notes and the Grid Gold  Acknowledgements  rank pari
passu with all other  unsecured,  unsubordinated  indebtedness of the Australian
Borrowers, other than obligations preferred by law.

                  10.  Based only on searches  referred to above,  no winding up
orders have been made or resolutions passed for the winding up of the Australian
Borrowers.


                                    VIII-B-4



                  11. The Australian  Borrowers does not enjoy any immunity from
suit  in  the  Courts  of the  Commonwealth  of  Australia  or  its  States  and
Territories and its assets are not exempt from execution.


                  This opinion is being delivered upon the express  instructions
of the  Australian  Borrowers to the Agents,  Arranger and the Lenders and their
permitted  assignees  and  participants  and is  solely  for  their  benefit  in
connection with the above transactions.  This opinion may not be relied upon for
any other purpose,  or relied upon by any other person,  firm or corporation for
any purpose, without our prior written consent; provided,  however, that each of
the  Agents,  Arranger  and  the  Lenders  and  their  permitted  assignees  and
participants may provide this opinion (i) to bank examiners and other regulatory
authorities   should  they  so  request  or  in  connection  with  their  normal
examinations,  (ii) to its respective independent auditors and attorneys,  (iii)
pursuant to order or legal process of any court or governmental  agency, (iv) in
connection  with  any  action  to  which  it  is a  party  arising  out  of  the
transactions  contemplated  by the  Credit  Agreement,  or  (v)  to  prospective
assignees  of, or  participants  in, all or any  portion of its Loans,  Bankers'
Acceptances, participations in Letters or Credit or Overall Commitment under the
Credit Agreement.


Yours very truly,



                                    VIII-B-5

                  Deutsche  Bank  A.G.  as  Documentation  Agent  and The  Chase
                  Manhattan Bank, as Administrative Agent


Ladies and Gentlemen:

                  We have  acted as  counsel  to The Chase  Manhattan  Bank,  as
Administrative Agent (in such capacity,  "Administrative  Agent"), in connection
with the preparation  and delivery of that certain Credit  Agreement dated as of
July 14,  1998 (the  "Credit  Agreement")  among  Homestake  Mining  Company,  a
Delaware  corporation  ("Company"),  Homestake  Mining Company of California,  a
California  corporation  ("U.S.  Borrower"),  Homestake  Canada Inc., an Ontario
corporation ("Canadian Borrower"),  Homestake Gold of Australia Limited, a South
Australia  corporation  ("HGAL"),  Plutonic Resources Limited, a New South Wales
corporation ("Plutonic"; and collectively with HGAL, "Australian Borrowers") the
financial institutions listed therein as the Lenders (collectively,  "Lenders"),
the Agents named therein (including the  Administrative  Agent) and the Arranger
named therein and in  connection  with the  preparation  and delivery of certain
related documents.

                  We   have    participated   in   various    conferences   with
representatives of the Company, U.S. Borrower, Canadian Borrower, and Australian
Borrowers and with your representatives and Blake,  Cassels & Graydon,  Canadian
counsel for the Agents, and Mallesons Stephen Jaques, Australian counsel for the
Agents,  during  which  the  Credit  Agreement  and  related  matters  have been
discussed,  and we have also participated in the meeting held on the date hereof
incident to the occurrence of the Effective Date under the Credit Agreement.

                  We have  reviewed  the forms of the Credit  Agreement  and the
exhibits  thereto,  including the promissory  notes delivered by U.S.  Borrower,
Canadian Borrower,  HGAL, and Plutonic, which forms are annexed thereto, and the
U.S. Grid Gold Acknowledgement,  which form is annexed thereto, and the opinions
of Wayne Kirk, Esq., General Counsel of Company,  Thelen, Reid & Priest, special
New York counsel to Company and  Borrowers,  Osler,  Hoskin & Harcourt,  special
Canadian counsel to Canadian  Borrower,  and Mallesons  Stephen Jaques,  special
Australian counsel to Australian Borrowers (collectively,  the "Opinions"),  and
the officers' certificates and other documents delivered on the Effective Date.


                                      IX-2



                  We  have  assumed  the  genuineness  of  all  signatures,  the
authenticity of all documents submitted to us as originals or copies and the due
authority of all persons  executing  the same,  and we have relied as to factual
matters on the documents that we have reviewed.

                  Based on and subject to the  foregoing,  we are of the opinion
that the Credit Agreement  constitutes the legally valid and binding  obligation
of the  Company  and the  Borrowers,  enforceable  against  the  Company and the
Borrowers in accordance with its terms,  except as may be limited by bankruptcy,
insolvency, reorganization,  moratorium or similar laws relating to or affecting
creditors'  rights  generally   (including,   without   limitation,   fraudulent
conveyance  laws)  and by  general  principles  of  equity,  including,  without
limitation, concepts of materiality, reasonableness, good faith and fair dealing
and the possible  unavailability of specific  performance or injunctive  relief,
regardless of whether considered in a proceeding in equity or at law.

                  Our   opinion   in   the   preceding   paragraph   as  to  the
enforceability of the Credit Agreement is subject to:

                  (i)             public  policy  considerations,   statutes  or
                                  court decisions that may limit the rights of a
                                  party to obtain  indemnification  against  its
                                  own gross  negligence,  willful  misconduct or
                                  unlawful conduct;

                 (ii)             the     unenforceability     under     certain
                                  circumstances  of broadly  or  vaguely  stated
                                  waivers or  waivers  of rights  granted by law
                                  where the waivers are against public policy or
                                  prohibited by law;

                 (iii)            the     unenforceability     under     certain
                                  circumstances  of  provisions  appointing  one
                                  party  as  attorney-in-fact   for  an  adverse
                                  party;

                 (iv)             the unenforceability under certain 
                                  circumstances of choice of law provisions; and

                 (v)              the     unenforceability     under     certain
                                  circumstances  of rights of set-off granted to
                                  a Lender in  respect  of  amounts  owing by an
                                  Affiliate  of such  Lender or with  respect to
                                  loans  in  which   participations   have  been
                                  granted  purported  to be provided  for in the
                                  Credit Agreement.

                  We express no  opinion as to the effect of  non-compliance  by
you with any state or federal laws or regulations applicable to the transactions
contemplated by the Credit Agreement because of the nature of your business.

                  We advise you that  provisions of the Credit  Agreement  which
provide  for  jurisdiction  of the  courts of New York may not be binding on the
courts in the forum(s) selected or excluded.


                                      IX-3



                  In addition, although we have not independently considered all
of the matters  covered by the Opinions to the extent  necessary to enable us to
express the  conclusions  therein  stated,  we believe that the Opinions and the
officers'  certificates  and other  documents  delivered in connection  with the
execution and delivery of, and as conditions to the effectiveness of, the Credit
Agreement  are  substantially  responsive  to the  requirements  of  the  Credit
Agreement.

                  The law  covered by this  opinion  is  limited to the  present
federal  law of the United  States and the present law of the State of New York.
We express no  opinion as to the laws of any other  jurisdiction  and no opinion
regarding the statutes,  administrative  decisions,  rules or regulations of any
county,  municipality or special political subdivision or other local authority.
We  express  no  opinion   concerning   federal  or  state  securities  laws  or
regulations.


                  This   opinion  is   furnished   by  us  as  counsel  for  the
Administrative  Agent and may be relied upon by you only in connection  with the
Credit Agreement. It may not be used or relied upon by you for any other purpose
or by any other person for any purpose  whatsoever  without in each instance our
prior  written  consent.  You may,  however,  deliver a copy of this  opinion to
permitted   assignees  under  the  Credit  Agreement  in  connection  with  such
assignment,  and such assignees may rely on this opinion as if it were addressed
and had been delivered to them on the date hereof.




                                                   Respectfully submitted,

assumption [and the sale and purchase] described above.

effect to the assignment and  assumption  [and the sale and purchase]  described
above,  Assignee shall be a party to the Credit  Agreement as a Canadian  Lender

assignment  by Assignor  and the  assumption  by Assignee of the  Percentage  of
Assignor's rights and obligations with respect to Assignor's Canadian Commitment
and Canadian Allocation,  including its commitment to create and accept Bankers'
Acceptances,  and any  Canadian  Loans and  Bankers'  Acceptances  and  Assignor
Participations  outstanding  thereunder and all rights and obligations under the
Loan  Documents  with  respect  thereto  [and (B) the sale by  Assignor  and the
purchase by Assignee of the Assignee Participation],  (ii) any other assignments
by  Assignor  of a  portion  of its  rights  and  obligations  with  respect  to
Assignor's Canadian Commitment and Canadian Allocation, including its commitment

Acceptances or Assignor  Participations  outstanding thereunder [, and any other

Loans, the outstanding Bankers' Acceptances,  or the aggregate  participation in

principal and accrued but unpaid  interest and  commitment  and letter of credit
fees with  respect  thereto) to  Assignee,  whether such amounts (in the case of

other Person liable for the payment of any  Obligations,  nor shall  Assignor be
required to ascertain or inquire as to the  performance  or observance of any of

to  make  its own  appraisal  of the  creditworthiness  of the  Company  and the
Borrowers. Assignor shall not have any duty or responsibility,  either initially
or on a continuing  basis, to make any such  investigation or any such appraisal
on  behalf  of  Assignee  or to  provide  Assignee  with  any  credit  or  other
information with respect thereto,  whether coming into its possession before the
making of the initial  Loans or at any time or times  thereafter,  and  Assignor
shall  not  have any  responsibility  with  respect  to the  accuracy  of or the

(as set forth on Annex 1 annexed hereto) of the aggregate Overall  Commitment of
all Lending Units as in effect at any time on and after the date this  Amendment
becomes effective.

                  (e)  The  parties   hereto   acknowledge   the  provisions  of
subsection  2.2F of the  Credit  Agreement  relating  to  disclosure  under  the
