         Continental Collateral Location or Goodman Collateral Location (or such
         other percentages of each Borrower's respective Eligible Inventory as
         may from time to time be fixed by the

         fixed by the Lender upon notice to the Borrowers)."

Except as otherwise modified herein, the remainder of Section 2.3 shall remain

         pay to Lender on March 28, 2000 and on June 30, 2001 and each
         succeeding June 30 thereafter (provided no such fee shall be taken on
         June 30, 2003 unless the maturity of the Revolving Loan is extended
         beyond said date), a commitment fee (the "Commitment Fee") of
         Twenty-five (25) basis points on the amount of the line of credit

         and continuing on the first day of each October, January, April and
         July thereafter. "Unused Line Fee" means a fee equal to the quotient of

         1999, and ending on June 30, 2003, the maturity date of the Revolving
         Loan."

SECTION II.  Amendment of Promissory Note

         A. The first two paragraphs of page 1 of the Note are, effective the
date hereof, hereby amended and restated to read in their entirety as follows:

                  FOR VALUE RECEIVED, CONTINENTAL CONVEYOR & EQUIPMENT COMPANY,
         a Delaware corporation, and GOODMAN CONVEYOR COMPANY, a Delaware
         corporation (hereinafter each referred to as a "Company" and
         collectively as the "Companies"), jointly and severally promise to pay
         to the order of BANK ONE, NA (hereinafter referred to as the "Bank"),

         or such lesser amount as shall have from time to time been borrowed by
         the Companies, on June 30, 2003, or sooner as hereinafter provided,
         with interest on the unpaid balance of said principal amount from the
         date hereof at the Contract Rate, as defined in the Agreement

         Company, as the same may from time to time be

                                       4
<PAGE>   5

         established. If any installment of principal, interest or other amounts
         due and payable hereunder are not paid when due, or within any
         applicable grace periods, the Companies shall pay interest thereon at
         the rate per annum of two-percent (2%) in excess of the Contract Rate,
         as the same may from time to time be established.

                  The Companies jointly and severally agree to pay interest on
         the unpaid principal amount outstanding of this Note in monthly
         installments commencing on the 1st day of April, 2000, and continuing

         B. The fourth paragraph of page 1 of the Note, which paragraph carries
over to page 2 of the Note, is, effective the date hereof, hereby amended and
restated to read in its entirety as follows:

                  This Note is issued pursuant to and is entitled to the
         benefits of a Credit Facility and Security Agreement dated as of
         September 14, 1992 by and between CONTINENTAL CONVEYOR & EQUIPMENT CO.
         L.P., a limited partnership organized and formerly existing under the
         laws of the State of Delaware, and GOODMAN CONVEYOR CO. L.P., a limited
         partnership organized and formerly existing under the laws of the State
         of Delaware (such partnerships hereinafter referred to as the "Original
         Borrowers") and the Bank, as amended by that certain First Amendment to
         Credit Facility and Security Agreement executed on August 27, 1993, by
         that certain Second Amendatory Agreement dated as of October 5, 1994,
         by that certain Consolidated Amendment No. 2 to Credit Facility and
         Security Agreement dated as of December 13, 1996, all by and among the
         Original Borrowers and the Bank, and as further amended by that Certain
         Third Amendatory Agreement by and among the Companies and the Bank
         dated March 28, 1997, by that certain Fourth Amendatory Agreement by
         and among the Companies and the Bank dated as of December, 1998, by
         that certain Fifth Amendatory Agreement by and among the Companies and
         the Bank dated as of April 29, 1999, by that certain Sixth Amendatory
         Agreement by and among the Companies and the Bank dated as of March 28,
         2000, and by any further amendments modifications or restatements
         entered into between the Companies and the Bank from time to time

         a statement of the rights and obligations of the Bank and the duties
         and obligations of each Company in relation thereto; but neither this
         reference to said Agreement nor any provisions thereof shall affect or
         impair the absolute and unconditional obligation of each Company to pay
         the principal of or interest on this Note when due. This Note has been
         issued pursuant to the Agreement in substitution for a certain existing
         Amended and Restated Replacement Promissory Note (Revolving Loan) dated

         and Restated Promissory Note (Revolving Loan) dated September 14, 1992

         It is understood and acknowledged by each Company that this Note is not
         intended as a novation of the obligations of the Original Borrowers and
         two Companies under the Old Notes but is merely a restatement of the
         obligations thereunder and under the Agreement, after giving effect to
         the most recent amendatory agreement thereto.

SECTION III.  Conditions Precedent

         Each Borrower hereby understands and agrees that the effectiveness of

                  contemplated hereby.

         If Lender shall consummate the transactions contemplated hereby prior

OVERDRAFT FACILITY
APPROVAL ADVICE

Customer's Name:   Continental Ace Pty Limited.
Overdraft Limit:   $3,000,000.00.
Expiry Date:       31st July, 2000.
Account Number:

This Approval Advice is the contract between you and the Bank for the Overdraft
Facility ("Facility") which is outlined in this Advice. It has been written in
plain English and is designed to be easily read and understood.

If you do have any problems or questions, please ring me on 49394312.

GENERAL

The terms and conditions which will apply to your Facility are those contained
in this Approval Advice and also the Bank's usual terms and conditions for the
operation of current accounts. These terms and conditions are available from any
branch of the Bank.

OVERDRAFT LIMIT

Your Overdraft Limit is $3,000,000.00. The Bank will allow you to overdraw the
Account Number detailed above up to the Overdraft Limit.

The Facility must be kept within the Overdraft Limit. Any excesses over the
Overdraft Limit require the prior approval of the Bank. Excesses will attract an
additional interest charge.

ARRANGING THE FACILITY

You authorise the Bank to open the Facility in your name and to debit to the
account each drawing you make or authorise and any other amount which you must
pay on the date it becomes due.

You may overdraw to the Overdraft Limit. However, the Facility is only available
if:

(a)      you overdraw before the Expiry Date; and
(b)      the Bank has received each security listed in this Approval Advice in a
         form satisfactory to it; and
(c)      any property covered by a security has been insured against fire and
         other usual risks with an insurer acceptable to the Bank; and
(d)      any property covered by a security referred to in (b) and (c) above has
         the Bank's interest noted on each insurance policy; and
(e)      any necessary corporate or trustee authorisations have been obtained;
         and
(f)      you are not in default under this Agreement (for example, by not paying
         a fee).

                                       2

FACILITY OPERATION

The Facility is to be fully fluctuating in accordance with your agreed working
needs.

You may operate the Facility by cheque or approved card through EFTPOS and the
Bank's Automatic Teller Machine network.

INTEREST RATE

The interest rate under the Facility is VARIABLE.

Your current annual percentage rate is 8.50% per annum, WHICH MAY VARY.

The annual percentage rate is the total of the Bank's Lending Indicator Rate
plus a customer margin of 0.00% per annum. The Bank's Lending Indicator Rate for
the Facility is Base Rate.

Movements in the Bank's Lending Indicator Rate can be monitored by you, as the
rate is published by the Bank in the metropolitan daily press on a Monday
(except Christmas day) under the heading "National Australia Bank Indicator
Rates". Such changes will also be recorded on your bank statement.

The default annual percentage rate is the total of the Bank's Lending Indicator
Rate PLUS the customer margin referred to above, plus a default margin of 4.00%.
The current default annual percentage rate is 12.50% per annum, WHICH MAY VARY.

The Bank calculates interest daily at the annual percentage rate divided by 365
on the unpaid daily balance of the account at the end of each day. The Bank
debits interest to the account on the last Business Day of each month.

If you overdraw more than the Overdraft Limit, with or without the prior
agreement of the Bank, or if you do not pay when required under any of
conditions (a) to (g) of Events of Default, interest on any excess will be
charged at the default annual percentage rate.

This interest is calculated at the default annual percentage rate so long as the
excess or default exists.

The Bank may change the Bank's Lending Indicator Rate, the customer margin and
the default margin. However, the Bank will advise you in writing prior to any
such variation taking effect.

REPAYMENT

You may pay any moneys to the credit of your account at any branch of the Bank
that is open for business or by approved card through one of the Bank's
FlexiTellers (Automatic Teller Machines).

You may also pay any moneys to the credit of your account at any branch of any
other bank in Australia, on the terms and conditions on which the other bank
accepts such transactions.

                                       3
<PAGE>   4

The Bank will use any payment to the credit of your account to pay: firstly,
fees, charges, enforcement expenses (if any) and similar payments; secondly,
interest charges; and thirdly, the outstanding balance of the account.

The whole of the balance owing under the Facility and any other money owing
under this Agreement must be paid to the Bank if you are in default as specified
below AND the default remains unremedied after the Bank gives you a notice
specifying the default.

EVENTS OF DEFAULT

Default occurs when:

(a)      there is a breach of any of these terms and conditions of the Facility
         or of a provision of any security or other agreement you have with the
         Bank; or
(b)      the Expiry Date shown above occurs and you owe the Bank any money under
         this Agreement; or
(c)      if in the Bank's opinion there has been a material adverse change in
         your financial position; or
(d)      any information given to the Bank at any time is false or, in the
         Bank's opinion, misleading; or
(e)      you or anyone who gives a security becomes bankrupt or insolvent, or
         you or such person goes into liquidation or receivership or has an
         administrator appointed; or
(f)      you assign your estate, or anyone who gives a security assigns their
         estate, to a creditor; or
(g)      any security under this Agreement becomes unenforceable.

The Facility will end immediately upon the occurrence of any event referred to
in conditions (a) to (g) or if you are otherwise in default of this Agreement.

Enforcement expenses may become payable by you in the event of a breach or if
you are in default of this Agreement.

WHEREAS

A.       The Companies and persons specified in Item 1 of the Schedule executing
         this Guarantee are hereinafter collectively called "Guarantors" and
         each of which is hereinafter separately referred to as a "Guarantor"
         and includes the legal personal representatives of each such person and
         in the case of a corporation its successors and assigns and they are
         mutually interested or are otherwise concerned in the respective
         business of the Guarantors and as customers of the Bank some or all of
         the Guarantors have obtained or may hereafter obtain banking
         accommodation from the Bank or incur liabilities to the Bank.

B.       It is possible that the Guarantors or any one or more of them will in
         the future acquire the whole of the issued capital or the whole of the
         issued ordinary capital of other companies (hereinafter called "other
         Companies") which other Companies may or may not together with the
         Guarantors or any of them or with each other become mutually interested
         or concerned in the respective businesses of the Guarantors.

C.       It is contemplated that the other Companies will become customers of
         the Bank and that some or all of them may seek and obtain banking
         accommodation from the Bank or incur liabilities to the Bank.

D.       It is for the mutual benefit of the Guarantors and the other Companies
         that the respective debts or liabilities to the Bank of those of the
         Guarantors and the other Companies who for the time being are or may be
         customers of the Bank and as such indebted to the Bank should be
         secured to the Bank by the mutual guarantees of each other.

IN CONSIDERATION of the Bank at the request of the Guarantors making loans and
advances or providing banking accommodation to all or any one or more of the
Guarantors and the other Companies whether alone or jointly or in conjunction
with any other person and/or in consideration of the Bank forbearing to enforce
immediate payment of the moneys (if any) now due and owing by all or any one or
more of the Guarantors to the Bank each of the Guarantors jointly and severally
agree with and guarantee to and indemnify the Bank and shall keep the Bank
indemnified as follows:-

1.       Each of the Guarantors will pay to the Bank on demand (whether any of
         the Guarantors or the other companies is then in default or not) the
         moneys hereby secured.

2.       Each Guarantor indemnities the Bank against:-

         (a)      any loss the Bank may suffer by reason of any other of the
                  Guarantors being an infant or an incorporated or
                  unincorporated body or a committee or a trustee or other
                  person acting in a fiduciary or representative capacity having
                  exceeded his powers or being incompetent to borrow, to
                  otherwise raise funds, or to incur any other liability or
                  obligation to the Bank;

         (b)      any loss the Bank may suffer by reason of any other of the
                  Guarantors becoming bankrupt, going into liquidation, being
                  placed under official management or making any arrangement,
                  assignment or composition (including any amount paid to the
                  Bank which the Bank may subsequently be obliged to pay out on
                  the ground that the payment of such amount to the Bank was a
                  preference) and including the amount of any interest (whether
                  capitalised or current) which does not accrue from the date of
                  such bankruptcy, liquidation, arrangement, assignment or
                  composition and/or is not recoverable by reason of the
                  happening of such event and which would otherwise have accrued
                  and have been recoverable from a Guarantor under the preceding

                                       9
<PAGE>   10

                  provisions of this Guarantee, AND it is agreed that in order
                  to secure the indemnity contained in this paragraph (b) the
                  Bank may retain any securities held by it for a period of 7
                  months from the date of any such event, or the date when the
                  moneys hereby secured are paid in full, whichever date shall
                  be the later;

         (c)      all costs, charges and expenses which, in the event of the
                  insolvency, bankruptcy, liquidation or official management of
                  or arrangement, assignment or composition by a Guarantor are
                  incurred by the Bank in defending or commencing any action by
                  or against any official receiver or trustee in bankruptcy,
                  receiver or liquidator or official manager of the Guarantor
                  which in the event of any such action being determined in
                  favour of the Bank would result in either the Guarantor being
                  entitled to demand from the Bank all or part of the moneys
                  already paid to the Bank as aforesaid or the liability of a
                  Guarantor under this Guarantee being reduced or discharged;
                  and

         (d)      all other costs, charges and expenses included in the
                  expression "the moneys hereby secured".

3.       (i)      This Guarantee is to be security for the whole of the moneys
                  and other liabilities which the Guarantors under Clauses 1 and
                  2 hereof are liable to pay but (subject to sub-clause (ii) of
                  this clause) the Guarantors and the other Companies shall not,
                  subject to Clause 4 hereof, be compelled to pay any amount
                  exceeding an amount (hereinafter called "the limit of the
                  guarantee") being the aggregate of:-

                  (a)      the basic liability set out in Item 2 of the
                           Schedule, and

                  (b)      a sum equivalent to one year's interest on the basic
                           liability calculated at the rate or, if more than one
                           rate, at the highest rate payable by a Guarantor at
                           the date of service of demand upon the Guarantor, and

                  (c)      a sum equivalent to the amount of any bank charges
                           and any other charges, costs and expenses payable
                           under Clauses 1 and 2 hereof PROVIDED THAT such sum
                           shall be limited to a sum equivalent to the whole of
                           such bank charges, other charges, costs and expenses
                           which have become payable under Clauses 1 and 2
                           hereof from a date twelve months prior to the date
                           upon which demand is made upon the Guarantors.

         (ii)     If no sum appears in Item 2 of the Schedule, or if the words
                  `unlimited as to amount' (or words to like effect) appear
                  therein, then the liability of the Guarantors hereunder shall
                  be unlimited as to amount.

                  have been paid.

6.       The Bank may enforce this Guarantee against a Guarantor notwithstanding
         that any bills or other instruments or any liability of a Guarantor
         covered by it may be in circulation, outstanding or not then due and
         payable.

7.       Whilst any moneys or other liabilities are owing or outstanding from a
         Guarantor to the Bank (whether or not a Guarantor is liable hereunder

         in any way claim the benefit or seek the transfer of any security or
         any part thereof, and generally waive in favour of the Bank all rights
         against the Bank and the other Companies and any other person, estates

         Guarantor to the Bank, it will not prove in the liquidation or
         bankruptcy of any other Guarantor with respect to any amounts owing to
         it by that other Guarantor on any account whatsoever.

                  the Guarantors conduct an account; and

         (b)      making payment in full of an amount equal to the moneys hereby
                  secured at the time of delivery of such notice (having regard
                  in particular to the operation of paragraphs (f) and (g) of
                  the definition of "the moneys hereby secured") up to the limit
                  of the guarantee, or provision for such payment.

9.       All moneys received by the Bank from or on account of the Guarantors
         and the other Companies or any of them (including any dividends upon
         the bankruptcy or liquidation of or any arrangement, assignment or
         composition by any one or more of the Guarantors and the other
         Companies or any of them) or from any other person or from the
         realisation or enforcement of any security capable of being applied by
         the Bank in reduction of the moneys hereby secured shall be regarded
         for all purposes as payments in gross, without any right on the part of
         any of the Guarantors to stand in the place of the Bank or claim the
         benefit of any moneys so received, until the Guarantors have paid the
         moneys hereby secured and so that in the event of any one or more of
         the Guarantors becoming bankrupt or making any arrangement, assignment
         or composition or going into liquidation the Bank shall be entitled to
         prove for the moneys hereby secured up to the limit of the Guarantee.

10.      In the event of the insolvency, bankruptcy, official management or
         liquidation of or arrangement, assignment or composition by any of the
         Guarantors and the other Companies the Bank is authorised by the
         Guarantors and the other Companies to prove for all moneys which the
         Guarantors and the other Companies shall have paid hereunder and to
         retain and to carry to a suspense account and appropriate at the Bank's
         discretion any dividends

                                       12
<PAGE>   13

         received until the Bank has, with the aid thereof, been paid the moneys
         hereby secured in full.

11.      This Guarantee and the Bank's rights and remedies hereunder shall not
         merge or prejudicially affect nor be merged in or prejudicially
         affected by any other security or securities now held or which may
         hereafter be held by the Bank but the Bank's rights and remedies under
         this Guarantee and any other security as aforesaid shall co-exist
         notwithstanding any rule of law or equity to the contrary. This
         Guarantee shall be in addition to every such other security. Nothing
         herein contained or implied shall merge the remedy of the Bank on any
         negotiable instrument or for money lent or for money paid or otherwise
         on simple contract.

12.      Where this Guarantee is given by a Guarantor as trustee of the trust
         shortly described in Item 3 of the Schedule, the liability of a
         Guarantor hereunder shall extend to him personally and to him as such
         trustee, and each Guarantor warrants that all of the powers and
         discretions conferred on him as such trustee are at the date hereof
         capable of being validly exercised by him and that the same have not
         been varied or revoked and that the same empower and permit a Guarantor
         to execute this Guarantee as trustee and that a Guarantor is entitled
         to be indemnified out of the trust estate for the liabilities and
         obligations assumed by him hereunder.

13.      ANY notice or certificate to be given to or demand to be made upon a
         Guarantor or any appointment to be made by or on behalf of the Bank
         hereunder shall be deemed to be duly given or made if the same be in
         writing and be signed by any person purporting to be any class of
         Manager or Accountant for the time being of the Bank and if the same be
         left at or sent through the post in a prepaid letter addressed to a
         Guarantor at the usual place of abode or business of the Guarantor in
         the said State or elsewhere last known as such to the person signing
         such notice, certificate or demand or delivered personally to a
         Guarantor and any such mode of service shall in all respects be valid

         Guarantor may be lunatic, dead, bankrupt or have assigned his estate or
         be absent from the said State, or being a company it should be in
         receivership or liquidation, whether voluntary or compulsory, and
         notwithstanding any other matter or event whatsoever. Any such notice,
         certificate or demand if sent through the post as aforesaid shall be
         deemed to have been received by a Guarantor at the time when the letter
         containing such notice, certificate or demand would in the ordinary
         course of post have been delivered.

14.      For the purposes of this Guarantee a certificate stating all or any of

         (ii)     that such an amount falls within a particular paragraph or

         legislation and regulations are hereby expressly excluded therefrom to
         the full extent permitted by law.

                  otherwise than by an instrument executed by the Bank by its
                  duly appointed attorney.

                  Companies (the date of such acquisition referred to as the

                  shall give notice thereof to the Bank and if so required by
                  the Bank shall procure that the other Company shall join in

                  imposed upon it hereunder shall be the same in all respects as
                  if the other Company had joined in this Guarantee as a
                  Guarantor as from the date of this Guarantee and the rights
                  and obligations and the restrictions imposed upon the other
                  Guarantors shall be the same in all respects as if the other
                  Company had joined in this Guarantee as from the date of this
                  Guarantee save in each case that none of the other Guarantors
                  shall have a right of contribution against the other Company
                  in relation to sums paid by such other Guarantor prior to the
                  Acquisition Date.

         (c)      The Bank shall forthwith give notice in writing (at any of the
                  addresses herein specified for the making of a demand on the
                  Guarantors and the new Guarantors) of the joining in this

"WARNING: This is an important document which makes the Guarantors fully and
separately responsible for all obligations of all types now or hereafter owing

person and whether or not the Guarantors have been informed about the size or
type of those obligations. Any mortgage or other security which the Guarantors
have given or hereafter give to the Bank in relation to their own affairs might
very well apply to any moneys due by the Guarantors under this document.

The Directors.
B.C.E.  Holdings Pty Limited.
Level 2, 40 Mann Street,
GOSFORD. N.S.W. 2250.

Dear Sirs,

CAPPED RATE BILL FACILITY

The Bank offers to provide to you a Capped Rate Bill Facility ("Facility") upon
the terms and conditions contained in the attached Bill Facility - Letter of
Offer ("Letter of Offer") dated 19th July, 1999, and this letter. This letter
supplements and should be read in conjunction with the Letter of Offer. Terms
defined in the Letter of Offer have the same meaning when used in this letter
unless the context otherwise requires and, in the event of inconsistency between
a provision of this letter and a provision of the Letter of Offer, the provision
in this letter prevails to the extent of that inconsistency.

DESCRIPTION OF THE FACILITY

The Facility is a floating rate bill facility under which, on each Drawdown Date
(as defined below), the Bank will accept Bills drawn and presented by you in
accordance with this letter and the Letter of Offer and discount the Bills at a
rate which is the lower of either:

(a)      the Drawdown Rate (as defined below) prevailing on the Drawdown Date,
         or

(b)      the Cap Rate (as defined below).

The following terms and conditions are applicable to the Facility.

1.       FACILITY AMOUNT: The amount set out at Item 4 of the Schedule to the
         Letter of Offer.

2.       FACILITY TERM: The Facility will commence on the Commencement Date
         specified at Item 6 of the Schedule to the Letter of Offer and expire
         on or about the date specified at Item 5 of the Schedule to the Letter
         of Offer. The Expiry Date is approximate only as the Bank will need to
         make some adjustment to conform with market requirements. However, the
         Expiry Date will be within 10 days of the selected date.

3.       CAP RATE: 4.00 per centum per annum.

4.       DRAWDOWN RATE: The Drawdown Rate means in respect of any day the rate
         of discount specified by the Bank in its discretion as the usual rate
         at which the Bank is prepared to

                                       21
<PAGE>   22

         purchase bills of exchange accepted by itself on that day which have a
         term and aggregate face amount matching the term and aggregate face
         amount of any Bills to be discounted on that day under this Facility.
         The Drawdown Rate is a floating rate (expressed as a per centum per
         annum yield to maturity) that varies from time to time.

         Subject to the terms of the Facility, on each Drawdown Date, Bills will
         be discounted at the Drawdown Rate prevailing on that date unless the
         Drawdown Rate exceeds the Cap Rate in which case Bills will be
         discounted at the Cap Rate.

5.       DRAWDOWN DATES AND DRAWDOWN ADVICE: The Drawdown Dates are the dates on
         which Bills drawn pursuant to the Facility are discounted. Following
         the commencement of this Facility, the Bank will provide you with a
         letter listing the Drawdown Dates for the Facility ("Drawdown Advice").
         The approximate period between each Drawdown Date will be 90 days.

6.       BILL REQUIREMENTS: Bills drawn under this Facility for acceptance and
         discount on a Drawdown Date should:

         (i)      be available to the Bank at least 5 Business Days before the
                  relevant Drawdown Date.

         (ii)     be drawn to mature on the next succeeding Drawdown Date or, if
                  there is no further Drawdown Date, on the Expiry Date.

         (iii)    have a face amount of $10,000.00 or an integral multiple
                  thereof and an aggregate face amount of at least $100,000.00
                  (see point 8 below).

         IMPORTANT NOTICE: If Bills are not drawn in accordance with this point
         6 or are not available to the Bank by the time referred to in point 6
         (i) ("Non-conforming Bills"), the Bank may, in its absolute discretion,
         either:

                  (a)      accept any Non-conforming Bills and discount the same
                           at the Drawdown Rate prevailing when the
                           Non-conforming Bills are presented whether or not the
                           Drawdown Rate is higher than the Cap Rate, or

                  (b)      accept any Non-conforming Bills but decline to
                           discount same.

7.       CAP PREMIUM: You must pay the bank a Cap Premium of $14,936-00 in total
         in respect of the Facility. The Cap Premium is payable by installments
         on each Drawdown Date. The amount of each installment is $3,734-00. The
         Bank may debit each installment of the Cap Premium from your account
         specified below:

                  Account Title:  Continental Ace Pty Limited.
                  Account Number:
                  Branch:         Maitland. N.S.W.

         IMPORTANT NOTICE: If you fail to pay any installment of the Cap Premium
         by the date that installment is due then, without affecting the Bank's
         other rights arising from failure to pay

                                       22
<PAGE>   23

         any amount under this Facility, the balance of the Cap Premium shall
         become immediately due and payable by you and may be debited by the
         Bank from your account specified above.

8.       PARTIAL DRAWDOWNS: You are not obliged to fully draw the Facility,
         however, partial drawdowns will be permitted only if the aggregate face
         amount of bills drawn is at least $100,000.00 or an integral multiple
         of $10,000.00 thereafter.

Please signify your acceptance of the above terms and conditions by signing the
copy of this letter where indicated.

Yours faithfully

John Incher,
Business Banking Manager

Level 2, 40 Mann Street,
GOSFORD. N.S.W. 2250.

Dear Sirs,

CAPPED RATE BILL FACILITY

The Bank offers to provide to you a Capped Rate Bill Facility ("Facility") upon
the terms and conditions contained in the attached Bill Facility - Letter of
Offer ("Letter of Offer") dated 19th July, 1999, and this letter. This letter
supplements and should be read in conjunction with the Letter of Offer. Terms
defined in the Letter of Offer have the same meaning when used in this letter
unless the context otherwise requires and, in the event of inconsistency between
a provision of this letter and a provision of the Letter of Offer, the provision
in this letter prevails to the extent of that inconsistency.

DESCRIPTION OF THE FACILITY

The Facility is a floating rate bill facility under which, on each Drawdown Date
(as defined below), the Bank will accept Bills drawn and presented by you in
accordance with this letter and the Letter of Offer and discount the Bills at a
rate which is the lower of either:

(a)      the Drawdown Rate (as defined below) prevailing on the Drawdown Date,

The following terms and conditions are applicable to the Facility.

1.       FACILITY AMOUNT: The amount set out at Item 4 of the Schedule to the
         Letter of Offer.

2.       FACILITY TERM: The Facility will commence on the Commencement Date
         specified at Item 6 of the Schedule to the Letter of Offer and expire
         on or about the date specified at Item 5 of the Schedule to the Letter
         of Offer. The Expiry Date is approximate only as the Bank will need to
         make some adjustment to conform with market requirements. However, the
         Expiry Date will be within 10 days of the selected date.

3.       CAP RATE: 4.00 per centum per annum.

4.       DRAWDOWN RATE: The Drawdown Rate means in respect of any day the rate
         of discount specified by the Bank in its discretion as the usual rate
         at which the Bank is prepared to

                                       24
<PAGE>   25
         purchase bills of exchange accepted by itself on that day which have a
         term and aggregate face amount matching the term and aggregate face
         amount of any Bills to be discounted on that day under this Facility.
         The Drawdown Rate is a floating rate (expressed as a per centum per
         annum yield to maturity) that varies from time to time.

         Subject to the terms of the Facility, on each Drawdown Date, Bills will
         be discounted at the Drawdown Rate prevailing on that date unless the
         Drawdown Rate exceeds the Cap Rate in which case Bills will be
         discounted at the Cap Rate.

5.       DRAWDOWN DATES AND DRAWDOWN ADVICE: The Drawdown Dates are the dates on
         which Bills drawn pursuant to the Facility are discounted. Following
         the commencement of this Facility, the Bank will provide you with a

         The approximate period between each Drawdown Date will be 90 days.

6.       BILL REQUIREMENTS: Bills drawn under this Facility for acceptance and
         discount on a Drawdown Date should:

         (i)      be available to the Bank at least 5 Business Days before the

         (ii)     be drawn to mature on the next succeeding Drawdown Date or, if

         (iii)    have a face amount of $10,000.00 or an integral multiple
                  thereof and an aggregate face amount of at least $100,000.00
                  (see point 8 below).

         IMPORTANT NOTICE: If Bills are not drawn in accordance with this point
         6 or are not available to the Bank by the time referred to in point 6
         (i) ("Non-conforming Bills"), the Bank may, in its absolute discretion,
         either:

                  (a)      accept any Non-conforming Bills and discount the same
                           at the Drawdown Rate prevailing when the
                           Non-conforming Bills are presented whether or not the
                           Drawdown Rate is higher than the Cap Rate, or

                  (b)      accept any Non-conforming Bills but decline to
                           discount same.

7.       CAP PREMIUM: You must pay the bank a Cap Premium of $43,704.00 in total
         in respect of the Facility. The Cap Premium is payable by installments
         on each Drawdown Date. The amount of each installment is $10,926.00.

         other rights arising from failure to pay

The covenants contained herewith in Annexure "A" form part of the Terms and
Conditions for all facilities approved in the name of Continental Conveyor and
Equipment Group.

*        Bill facility, $3,000,000.00, the initial term of the facility is to be
         restricted to 12 months.

*        The Bill facility, $3,000,000.00 is to be subject to principal
         reductions of $ 150,000.00 per quarter commencing from drawdown.

*        The Bill facility, $ 1,500,000.00 is to be subject to principal
         reductions of $300,000.00 per quarter commencing from drawdown.

*        The current Documentary Letters of Credit and or Bank Guarantees line
         of $4,000,000.00 is to reduce to $3,000,000.00 by 31st December, 1999,
         and further to $1,000,000.00 by 31st December, 2000.

*        The Bank will require Continental Conveyor & Equipment Company (CCEC)
         to provide a Letter of Awareness undertaking to retain its 100%
         ownership, to maintain the subsidiary in a solvent position (after
         exclusion of Shareholders loans) and to acknowledge the terms and
         conditions applying over facilities extended to B.C.E. Holdings Pty
         Limited.

*        Quarterly information package to be provided within 45 days of the
         quarter ended, commencing from the June, 1999, quarter, for each entity
         within the Group.

         The package is to comprise the following:

         -        Variance analysis of budget v's actual performance, detailed
                  comments on variances of more than 10%.

         -        Revised/updated cashflow forecasts to the financial year end
                  including assumptions.

*        Outstanding debtors of less than 90 days and excluding inter company
         positions are not to fall below $10m. Sufficient buffer is seen to

*        Quarterly management accounts are to be accompanied by aged listings of
         both debtors and creditors.

*        Whilst formal subordination of the parent loan of $13,500,000.00 (as at
         31st December, 1998) is acknowledged to be in contravention of US
         bankers covenants and accordingly is not available. The Bank requires
         an undertaking in writing from CCEC not to seek or allow repayment of
         these loans during the term of the Bank's facilities without our prior
         written approval.

*        Annual financial statements signed by the directors for all entities
         within the Group (including consolidated accounts) are to be provided
         to the Bank within 120 days from the financial year end (31st December,
         annually).

*        Change of ownership clause.

*        Interest cover to be not less than 2 times.

*        Dismantling Overdraft Set Off Group Arrangement.

         ownership, to maintain the subsidiary in a solvent position (after
         exclusion of Shareholders loans) and to acknowledge the terms and
         conditions applying over facilities extended to B.C.E. Holdings Pty
         Limited.

         within the Group.

         -        Variance analysis of budget v's actual performance, detailed
                  comments on variances of more than 10%.

*        Whilst formal subordination of the parent loan of $13,500,000.00 (as at

         bankers covenants and accordingly is not available. The Bank requires
         an undertaking in writing from CCEC not to seek or allow repayment of
         these loans during the term of the Bank's facilities without our prior
         written approval.
