     (1)  Commitment. The Credit Facility shall be made available, subject to
          the terms and conditions of this agreement, on a non-revolving basis
          in the principal amount of up to but not exceeding US$4 million (the
          "Commitment").

          assisting the Borrower to fund MASA's contribution towards completion
          of a bankable feasibility study for the Mine and related matters;

<PAGE>


                                       12

     (3)  Accommodations. Subject to the terms and conditions of this agreement,
          the Commitment shall be made available by the Lender to the Borrower
          in two advances, the first advance to be made under the First Tranche
          on the Closing Date and the second advance to be made under the Second
          Tranche following satisfaction of the conditions set forth in section
          3.2, in each case on written request therefor made by the Borrower at
          least two Business Days prior to the drawdown date (or such shorter
          period as may be agreed by the parties). Any portion of the Commitment
          allocated to a Tranche and not made available to the Borrower on the
          date such Tranche is advanced shall be permanently cancelled; provided
          that the failure to advance all of a Tranche shall not affect the
          number of Borrower Shares available under the First Tranche Warrants
          or the Second Tranche Warrants, as the case may be.

     (4)  Non-Revolving Repayments. The Credit Facility shall not revolve, and
          amounts repaid or prepaid thereunder may not be the subject of any
          further availment.

2.2  Repayment.(1) Maturity. The Principal Outstanding will be repaid in full on
     the Final Maturity Date.

     (2)  Prepayment. Notwithstanding section 2.2(1), the Borrower may prepay,
          in whole or in part, the principal amount outstanding under the Credit
          Facility at any time and from time to time, without penalty or bonus,
          upon the Borrower giving to the Lender two Business Days' prior
          irrevocable notice of such intention and provided that, on or before
          any such prepayment is made, the Lender has received payment of all
          interest accrued thereon and any Increased Costs with respect thereto.

2.3  Payments.

     (1)  Payment Account. The Borrower shall make each payment to be made
          hereunder not later than 11:00 a.m. (Sydney time) in US Dollars on the
          day (subject to section 2.3(2)) when due, in same day funds, by
          deposit of such funds to such account as the Lender shall specify.

     (2)  Business Day. Subject to the next following sentence, whenever any
          payment hereunder is due on a day other than a Business Day, such
          payment shall be made on the next succeeding Business Day, and such
          extension of time shall in such case be included in the computation of
          interest. If any such extension would cause any payment of interest to
          be made in the next following calendar month, such payment shall be
          made on the last preceding Business Day.

                                       13

fees payable by the Borrower hereunder shall be conclusive and binding for all
purposes, absent manifest error.

2.5 Facility Fees.The Borrower shall pay to the Lender at the time of advance of
each Tranche a facility fee of US$30,000.

2.6 Interest on Tranches.(1) General. The Borrower shall at all times during
each Interest Period for each Tranche pay interest on the Principal Outstanding
at a rate per annum equal to the sum of LIBOR for such Interest Period plus two
(2%) per cent, calculated daily and payable in US Dollars:

          (a)  at the end of such Interest Period (except where such Interest
               Period exceeds three months in duration, in which case such
               interest shall be payable on the dates falling every three months
               following the commencement of the Interest Period and, finally,
               at the end of such Interest Period); and

          (b)  when such Tranche becomes due and payable in full.

     (2)  Basis. All computations of interest based on LIBOR shall be made by
          the Lender on the basis of a year of 360 days and the actual number of
          days (including the first day but excluding the last day) occurring in
          the period for which such interest is payable.

     (3)  Determination by Lender. Each determination by the Lender of an amount
          of interest payable by the Borrower hereunder shall be conclusive and
          binding for all purposes, absent manifest error.

     (4)  Interest Act (Canada). For purposes of disclosure pursuant to the
          Interest Act (Canada), the yearly rate of interest to which any rate
          of interest based on LIBOR is equivalent may be determined by
          multiplying the applicable rate by a fraction, the numerator of which
          is the number of days to the same calendar date in the next calendar
          year (or 365 days if the calculation is made as of February 29) and
          the denominator of which is 360.

2.7 Interest on Overdue Amounts.Except as otherwise provided in this agreement,
each amount owed by the Borrower to the Lender which is not paid when due
(whether at stated maturity, on demand, by acceleration or otherwise) shall bear
interest (both before and after judgment), from the date on which such amount is
due until such amount is paid in full, payable on demand, at a rate per annum
equal at all times to the rate otherwise applicable thereto under this agreement
(including, for greater certainty, the two (2%) per cent margin over LIBOR set

<PAGE>


                                       14

forth in section 2.6(1)) plus a further two (2%) per cent per annum. With
respect to periods occurring after an Event of Default, such calculation of
overdue interest shall be made on the basis of such Interest Period(s) as the
Lender may reasonably select.

          duly observe all valid requirements of any Official Body, except to
          the extent failure to do so in the reasonable opinion of the Lender
          does not constitute, and could not reasonably be expected to
          constitute, an MAE.

          and when required by applicable Law all Tax returns and pay and
          discharge before the same shall become delinquent (a) all Taxes
          imposed upon it or upon its property, and (b) all lawful claims
          (including claims for labour, materials, supplies or services) which,
          if unpaid, might become a Lien upon its property, except in each case
          any such Tax or claim which is being contested in good faith and by
          proper proceedings and for which adequate reserves have been
          maintained and no Liens (except Permitted Encumbrances) have attached.

     (4)  Keeping of Books. It will, and will cause MASA to, keep proper books

          Lender as secured party, at all times take all action necessary to
          maintain the Liens provided for under or pursuant to this agreement
          and the Security as valid and perfected first Liens on the property
          intended to be covered thereby (subject only to Permitted
          Encumbrances) and supply all information to the Lender which is
          reasonably necessary for such maintenance.

          (b)  100% of the budgeted corporate expenditures and interest expenses
               to be paid by the Borrower in such immediately following calendar
               quarter;

          and at any time and from time to time shall provide to the Lender such
          information as the Lender shall reasonably request to confirm
          compliance herewith.

     (9)  Notice; Information. It will provide to the Lender:

          (a)  within 90 days of the end of each financial quarter, the
               unaudited consolidated financial statements of the Borrower; and

          (b)  within 120 days of the end of each financial year, the audited
               consolidated financial statements of the Borrower;

          (c)  prompt written notice of any Default or Event of Default;

          (d)  prompt written notice of any MAE or event which could reasonably
               be expected to constitute an MAE;

          (e)  promptly following the filing thereof by the Borrower, copies of
               all reports, statements and other material provided to
               shareholders or (other than on a confidential basis) to
               applicable securities regulatory agencies (including the TSX
               Venture Exchange); and

          (f)  such other information as the Lender may reasonably request from
               time to time (including with respect to the San Jose Project and
               the Borrower's financial condition).

     (10) Visitation, Inspection, etc. The Borrower will permit the Lender and
          its representatives and consultants to visit and inspect any the
          assets of the Borrower or MASA, to examine the books and records of
          the Borrower and MASA and to make copies and take extracts therefrom
          (as reasonably required), and to discuss its or any affiliate's
          affairs, finances and accounts with relevant officers or independent
          auditors, all at such reasonable times and as often as the Lender may
          reasonably request.

          Lender, the Lender's affiliates and the respective directors,
          officers, employees, agents and representatives of the Lender and such

          disbursements of any kind or nature whatsoever which may be imposed
          on, incurred by, or asserted against the indemnitees or any of them,
          directly or indirectly related to or arising out of any breach of any
          Environmental Law, or any release or the presence of hazardous
          materials, at any time relating to the assets or the operations of any
          of the Borrower, MASA or MSC; provided that no amount shall be payable
          under this section 6.1(11) to the extent that same arises out of the
          gross negligence or wilful misconduct of an indemnified person or a
          breach by an indemnified person of this agreement. The obligations of
          the Borrower under this section 6.1(11) shall survive the payment and
          performance of the Obligations.

     (12) San Jose. It will exercise its voting powers and such other reasonable
          means as are available to it so as to ensure that, without the prior
          written consent of the Lender, MASA will not reduce its interest in
          MSC and MSC will not reduce its interest in the San Jose Project (in
          each case whether same is comprised in the ownership of equity, the
          holding of convertible securities, the ownership of real property
          interests, mineral licences, tenures, tenements, or otherwise).

                    Scotia; and

                    of 24 months from the date of issuance of each Warrant.

          (b)  If any filing pursuant to any Applicable Securities Law of the
               Province of Alberta is required to ensure that the Warrants or
               any of the Borrower Shares issued upon the exercise thereof are
               issued in compliance with all such laws or to ensure that the
               Warrants or any such Borrower Shares, once issued, will not,
               following the expiration of four months and one day from the date
               of issuance of the Warrants, be subject to any resale
               restrictions under such Applicable Securities Laws (except
               restrictions relating to trades by control persons), the Borrower
               covenants that it shall take all such action as may be necessary
               to make such filing.

          the Lender, duly execute and deliver, or cause to be duly executed and
          delivered, to the Lender such further instruments and do and cause to

          reasonable opinion of the Lender to carry out more effectually the
          provisions and purposes of this agreement and the other Credit
          Facility Documents.

in addition to any other covenants herein set forth, the Borrower covenants and
agrees that it will not take any of the actions set forth in this section 6.2 or

          activity that is not related to mineral exploration, mining and

          assistance (whether by way of loan, guarantee, indemnity, agreement to
          acquire indebtedness or assets, or any other similar transaction

                                    ARTICLE 7
                            CHANGES IN CIRCUMSTANCES

7.1 Illegality.If the enactment of any applicable Law or any change therein or
in the interpretation or application thereof by any Official Body or compliance
by the Lender with any guideline, official directive, request or direction
(whether or not having the force of Law) of any Official Body hereafter makes it
unlawful for the Lender to make, fund or maintain a Tranche or to give effect to
its obligations hereunder, the Lender may by written notice thereof to the
Borrower declare its obligations under this agreement to be terminated,
whereupon the same shall forthwith terminate, and the Borrower shall within the
time required by such Law (or at the end of such longer period as the Lender at
its discretion has agreed) repay all Obligations to the Lender.

7.2 LIBOR.

If, on or before any date on which an interest rate is to be determined on the
basis of LIBOR, either:

          (a)  the Lender determines that it will not be possible to determine
               LIBOR for the applicable Interest Period or in the applicable
               amounts; or

          (b)  the Lender determines that LIBOR will not adequately reflect the
               cost of making, funding or maintaining a Tranche for the
               applicable Interest Period;

then, the Lender shall forthwith give notice of such event to the Borrower,
whereupon the obligations of the Lender to make LIBOR advances available to the
Borrower shall be suspended with respect to the relevant Tranche(s) until the
Lender gives notice to the Borrower that the circumstances giving rise to such
determination no longer exist.

In circumstances where LIBOR advances are not available, the relevant Tranche(s)
shall bear interest at such rate as the Lender shall advise the Borrower
compensates the Lender for its all-in cost of funds, together with the margin of

<PAGE>


                                       29

two (2%) per cent set forth in section 2.6(1) and, if applicable, the further
margin of two (2%) per cent in respect of overdue amounts set forth in section
2.7.

7.3  Indemnification.

     (1)  Matching Funds. The Borrower shall promptly pay to the Lender any
          amounts required to compensate the Lender for any breakage or similar
          cost, loss, cost of redeploying funds or other cost or expense
          suffered or incurred by the Lender as a result of:

          (a)  any payment being made by the Borrower in respect of a LIBOR
               advance (due to acceleration hereunder or for any other reason)
               on a day other than the last day of an Interest Period applicable
               thereto;

          (b)  the Borrower's failure to give notice in the manner and at the
               times required hereunder; or

          (c)  the failure of the Borrower to fulfil or honour, before the date
               specified for the advance of a Tranche, the applicable conditions
               set forth in Article 3 or to accept such advance in the manner
               and at the time specified in its request therefor.

          A certificate of the Lender submitted to the Borrower as to the amount
          necessary to so compensate the Lender shall be conclusive evidence,
          absent manifest error, of the amount due from the Borrower to the
          Lender.

     (2)  General. The Borrower agrees to indemnify the Lender and its
          affiliates, and the directors, officers and employees of each of them,
          from and against any and all liabilities, obligations, losses,
          damages, penalties, actions, judgments, suits, costs, expenses or
          disbursements of any kind or nature whatsoever which may be imposed
          on, incurred by, or asserted against the indemnitees or any of them,
          related to or arising out of the transactions contemplated hereunder
          or under any other Credit Facility Document; provided that no amount
          shall be payable under this section 7.3(2) to the extent that same
          arises out of the gross negligence or wilful misconduct of an
          indemnified person or a breach by an indemnified person of this
          agreement.

7.4  Taxes, Costs, Etc.

     (1)  Gross-Up. Any and all payments by the Borrower under this agreement or
          any other Credit Facility Document shall be made free and clear of and
          without deduction or withholding for Taxes unless such Taxes are

<PAGE>


                                       30

          required by Law to be deducted or withheld. If the Borrower shall be
          required by Law to deduct or withhold any Taxes from or in respect of
          any sum payable hereunder or thereunder:

          (a)  the sum payable shall be increased as may be necessary so that
               after making all required deductions or withholdings (including
               deductions or withholdings applicable to additional amounts paid
               under this section) the Lender receives an amount equal to the
               sum it would have received if no deduction or withholding had
               been made;

          (b)  the Borrower shall make such deductions or withholdings; and

          (c)  the Borrower shall pay the full amount deducted or withheld to
               the relevant taxation or other authority in accordance with
               applicable Law.

          Within 30 days after paying any sum from which it is required by Law
          to make any deduction or withholding, and within thirty days after the
          due date of payment of any Tax which it is required by section
          7.4(1)(b) to pay, the Borrower shall deliver to the Lender an official
          receipt or other evidence reasonably satisfactory to the Lender of
          such deduction, withholding or payment and of the remittance thereof
          to the relevant Official Body.

     (2)  Pay Taxes. The Borrower shall pay all Taxes which arise from any
          payment made hereunder or under any other Credit Facility Document or
          from the execution, delivery or registration of, or otherwise with
          respect to, this agreement or such other Credit Facility Document.

     (3)  Indemnity. The Borrower shall indemnify and save harmless the Lender
          for the full amount of Taxes (including any Taxes imposed by any
          jurisdiction on amounts payable under this section) paid by the Lender
          and any liability (including penalties, interest and expense) arising
          therefrom or with respect thereto, whether or not such Taxes were
          correctly or legally asserted. Payment under this indemnification
          shall be made within 30 days from the date the Lender makes written
          demand therefor. A certificate as to the amount of such Taxes
          submitted by the Lender to the Borrower shall be conclusive evidence,
          absent manifest error, of the amount due from the Borrower to the
          Lender.

     (4)  Survival. Without prejudice to the survival of any other agreement or
          obligation of the Borrower hereunder or under any other Credit
          Facility Document, the obligations of the Borrower under this section
          7.4 shall survive the payment and performance of the Obligations.(5)

<PAGE>


                                       31

          Limitation. The Lender shall exercise reasonable commercial efforts to
          limit the incidence of any additional amounts payable under this
          section 7.4, and the Borrower shall not be obligated to pay any such
          amounts to the extent that they arise after the cause of same is
          rescinded, removed, repealed or withdrawn.(6) The Lender agrees not to
          assign the Credit Facility, or any portion thereof, to any assignee
          which would result in the obligations of the Borrower under section
          7.4(1) above becoming more onerous in any material respect (determined
          immediately after such assignment), including an increase in the
          amount of the required deductions or withholdings. 7.5 Increased
          Costs.If:

          (a)  the enactment or amendment of any Law or any change in the
               interpretation or application thereof by any Official Body; or

          (b)  compliance by the Lender with any amendment or change to any
               existing directive, request or requirement (whether or not having
               the force of Law) of any Official Body or with any new such
               directive, request or requirement;

shall have the effect of:

          (c)  increasing the cost to the Lender of performing its obligations
               under this agreement or in respect of the Credit Facility,
               including the costs of maintaining any capital, reserve or
               special deposit requirements with respect to this agreement or
               the Credit Facility or with respect to its obligations hereunder;

          (d)  requiring the Lender to maintain or allocate any capital
               (including a requirement affecting the Lender's allocation of
               capital to its obligations) or additional capital in respect of
               its obligations under this agreement or in respect of the Credit
               Facility or otherwise reducing the effective return to the Lender
               under this agreement or in respect of the Credit Facility or on
               its total capital as a result of entering into this agreement or
               making the Credit Facility available;

          (e)  reducing any amount payable to it by or in an amount it deems
               material (other than a reduction resulting from a higher rate of
               income or capital Tax or other special Tax relating to the
               Lender's income or capital in general); or

          (f)  causing the Lender to make any payment or to forgo any return on
               or calculated by reference to any amount received or receivable
               by the Lender under this agreement or in respect of the Credit
               Facility;

<PAGE>


                                       32

then the Lender may give notice to the Borrower specifying the nature of the
event giving rise to such additional cost, reduction, payment or forgone return
and the Borrower shall promptly pay such amounts as the Lender may specify to be
necessary to compensate it for any such additional cost, reduction, payment or
forgone return. A certificate setting out, in reasonable detail, the amount of
any such additional cost, reduction, payment or forgone return, submitted in
good faith by the Lender to the Borrower, shall be conclusive and binding for
all purposes absent manifest error.

                                    ARTICLE 8
                                EVENTS OF DEFAULT

          interest, fees, expenses, indemnity or otherwise) and the same shall
          remain unpaid for three Business Days after the due date.

     (2)  Representations and Warranties Incorrect. Any of the representations
          or warranties made or deemed to be made by the Borrower or MASA in any

     (3)  Failure to Perform Covenants. Other than in respect of those covenants
          referred to in section 8.1(4), either the Borrower or MASA shall fail
          to perform or observe any covenant contained in this agreement or any
          other Credit Facility Document on its part to be performed or observed
          or otherwise applicable to it; provided that, if such failure is
          capable of being remedied, no Event of Default shall have occurred as
          a result thereof unless and until such failure shall have remained
          unremedied for 14 days after the earlier of (i) written notice thereof
          has been given to the Borrower by the Lender, and (ii) such time as
          such person is aware of same.

     (4)  Ibid. Either the Borrower or MASA shall fail to perform or observe any
          covenant contained in section 6.1(1)(a), 6.1(6) or 6.2 on its part to

               either the Borrower or MASA to any other person in an amount in
               excess of US$100,000 (or the equivalent amount in other
               currencies), unless the Borrower or (as the case may be) MASA
               shall, to the satisfaction of the Lender, be diligently,
               continuously and in good faith taking all appropriate proceedings
               and other steps to dispute same.

     (6)  Voluntary Events of Bankruptcy. Any of the Borrower, MASA or MSC
          shall:

          (a)  apply for or consent to the appointment of, or the taking of

               part of its assets;

               composition of it or its debts under any statute, rule or
               regulation relating to bankruptcy, insolvency, reorganization,
               relief or protection of debtors or at common law or in equity; or

          (e)  take any corporate action to authorize any of the actions
               described in this section 8.1(6).

(c)               has resulted in the appointment of a receiver, custodian,
                  administrator, trustee, liquidator or other similar official
                  for it or any material part of its assets.

     (8)  Execution. All or any material part of the assets of the Borrower or
          MASA are attached, executed, sequestered or distrained upon or become
          subject to any order of a court or other process and such attachment,
          execution, sequestration, distraint, order or process (a) relates to
          claims in the aggregate in excess of US$100,000 (or the equivalent
          amount in other currencies), and (b) such person shall not discharge

     (10) Security Unenforceable. Any Credit Facility Document shall become
          unenforceable or the Lien of the Security shall cease to rank in
          priority in the manner contemplated herein or in the Security other
          than by reason of the direct act or omission of the Lender.

     (11) MAE. In the opinion of the Lender, acting reasonably, an MAE shall

8.2  Effect.

     (1)  General. Upon the occurrence and continuance of an Event of Default,
          except as provided in section 8.2(2), the Lender may after the expiry
          of seven days:

               respect of the Commitment; and

          (b)  by notice to the Borrower declare the Obligations to be forthwith
               due and payable, without presentment, demand, protest or further
               notice of any kind, all of which are hereby expressly waived by
               the Borrower.

<PAGE>


                                       35

     (2)  Specific Defaults. If any Event of Default specified in section 8.1(6)
          or 8.1(7) shall occur, then all obligations of the Lender in respect
          of the Commitment shall be automatically cancelled and the Obligations
          shall be forthwith due and payable, all as if the request and notice
          specified in each of sections 8.2(1)(a) and 8.2(1)(b) had been
          received and given by the Lender.

     (3)  Enforcement. Upon the occurrence of an Event of Default and
          acceleration of the Obligations, the Lender may commence such legal
          action or proceedings as it may deem expedient, including exercising
          and enforcing its rights and remedies under the Security, all without
          any additional notice, presentation, demand, protest, notice of
          dishonour, entering into of possession of any property or assets, or
          any other action, notice of all of which the Borrower hereby expressly
          waives. The rights and remedies of the Lender hereunder and under the
          other Credit Facility Documents are cumulative and are in addition to
          and not in substitution for any other rights or remedies provided by
          Law.

9.1 Records.The Principal Outstanding and the unpaid interest accrued thereon
shall at all times be ascertained from the records of the Lender, which shall be
conclusive absent manifest error.

9.2 Amendments, etc.No amendment or waiver of any provision of this agreement or
of any other Credit Facility Document, nor any consent to any departure by the
Borrower or any other person herefrom or therefrom, shall in any event be
effective unless the same shall be in writing and signed by the Lender, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given.

     (1)  the negotiation of the commitment letter dated October 20, 2004 and
          the negotiation, preparation, execution, delivery and interpretation,
          both prior and subsequent to the Closing Date, of this agreement and
          any other Credit Facility Document (in this section 9.5, collectively,
          the "Documents");

     (2)  the performance by the Lender of its obligations and duties under any
          Document;

     (3)  advice of counsel with respect to the administration of or other
          matters relating to the Credit Facility, any Document or any
          transaction contemplated thereunder;

     (4)  the enforcement of any Document or the enforcement or preservation of
          rights under and the refinancing, renegotiation or restructuring
          (including negotiation of any so-called "workout" or similar
          transaction) of the Credit Facility under this agreement or any other
          Document or the bringing of any action, suit or proceeding with
          respect to the enforcement of any Document or any such right or
          seeking any remedy which may be available to the Lender at law or in
          equity; and

     (5)  any amendments, waivers or consents pursuant to the provisions hereof
          or any other Document.

9.6  Judgment Currency.

     (1)  Exchange Rate. If, for the purposes of obtaining judgment in any
          court, it is necessary to convert a sum due hereunder to the Lender in
          one currency (in this section 9.6, the "Original Currency") into
          another currency (in this section 9.6, the "Judgment Currency"), the
          parties agree, to the fullest extent that they may effectively do so,
          that the rate of exchange used shall be that at which in accordance
          with normal banking procedures the Lender could purchase the Original
          Currency with the Judgment Currency on the Business Day preceding that
          on which final judgment is paid or satisfied.

     (2)  Obligation. The obligations of the Borrower in respect of any sum due
          in the Original Currency from it to the Lender under any Credit
          Facility Document shall, notwithstanding any judgment in any Judgment
          Currency, be discharged only to the extent that, on the Business Day
          following receipt by the Lender of any sum adjudged to be so due in
          such Judgment Currency, the Lender may in accordance with normal
          banking procedures purchase the Original Currency with such Judgment
          Currency. If the amount of the Original Currency so purchased is less
          than the sum originally due to the Lender in the Original Currency,
          the Borrower agrees, as a separate obligation and notwithstanding any
          such judgment, to indemnify the Lender against such loss and, if the
          amount of the Original Currency so purchased exceeds the sum
          originally due to the Lender in the Original Currency, the Lender
          agrees to remit such excess to the Borrower.

9.7  Governing Law.

     (1)  Governing Law. This agreement shall be governed by and construed in
          accordance with the laws of the Province of British Columbia and the
          laws of Canada applicable therein.

     (2)  Submission to Jurisdiction. Each party hereby irrevocably submits to
          the jurisdiction of the courts of British Columbia in any action or
          proceeding arising out of or relating to this agreement and hereby
          irrevocably agrees that all claims in respect of any such action or
          proceeding may be heard and determined in such courts. Each party
          hereby irrevocably waives, to the fullest extent it may effectively do
          so, the defence of an inconvenient forum to the maintenance of such
          action or proceeding. Each party agrees that a final judgment in any
          such action or proceeding shall be conclusive and may be enforced in
          other jurisdictions by suit on the judgment or in any other manner
          provided by Law.

     (3)  Non-Exclusive. Nothing in this section 9.7 shall affect the right of
          any party to serve legal process in any other manner permitted by Law
          or affect the right of a party to bring any action or proceeding
          against another party or its property in the courts of other
          jurisdictions.

     (4)  Trial by Jury. Each of the parties hereto, to the fullest extent
          permitted by Law, hereby waives its rights to a trial by jury.

9.8  Successors and Assigns.

     (1)  Effectiveness. This agreement shall become effective when it shall
          have been executed by the Borrower and the Lender and thereafter shall
          be binding upon and enure to the benefit of each such person, its
          successors and permitted assigns.

                                       39

     (2)  Borrower not to Assign. The Borrower shall not have the right to
          assign its rights or obligations hereunder or any interest herein
          without the prior consent of the Lender, which consent may be
          arbitrarily withheld.

     (3)  Assignments. The Lender may assign (including by way of syndication or
          loan participation) all or any part of its interest in the Credit
          Facility to one or more persons (each an "Assignee") and, to the
          extent of any such assignment (unless otherwise stated therein), the
          assignee shall have the same rights and benefits hereunder and under
          the other Credit Facility Documents as it would have if it were the
          Lender hereunder; provided that any assignment (other than to an
          affiliate of the Lender) prior to a Default shall require the written
          consent of the Borrower, which consent shall not be unreasonably
          withheld.

     (4)  Assumption. In order to effect an assignment contemplated by section
          9.8(3), the Lender shall deliver to the Borrower (at the Lender's cost
          but exclusive of the fees of the Borrower's counsel) an agreement by
          which the Assignee assumes the obligations and agrees to be bound by
          all the terms and conditions of this agreement, all as if such
          Assignee had been an original party hereto. Upon any such assignment
          and such assumption of the obligations of the Lender by such Assignee,
          the Lender and the Borrower shall be mutually released from their
          respective obligations hereunder to the extent of such assignment and
          assumption and shall thenceforth have no liability or obligations to
          each other to such extent, except in respect of actions taken or
          matters which have arisen prior to such assignment.

9.9 Conflict.In the event of a conflict between the provisions of this agreement
and the provisions of any other Credit Facility Document, the provisions of this
agreement shall prevail.

9.10 Severability.The provisions of this agreement are intended to be severable.
If any provision of this agreement shall be held invalid or unenforceable in
whole or in part in any jurisdiction, such provision shall, as to such
jurisdiction, be ineffective to the extent of such invalidity or
unenforceability without in any manner affecting the validity or enforceability
thereof in any other jurisdiction or the remaining provisions hereof in any
jurisdiction.

9.11 Prior Understandings.This agreement supersedes all prior understandings and
agreements, whether written or oral, among the parties relating to the
transactions provided for herein.

shall be deemed an original and all of which, taken together, shall constitute
one and the same instrument, and may be delivered by a party by facsimile or
similar means of recorded communication.

their respective officers thereunto duly authorized, as of the date first above
