ITEM 2.     ACQUISITION OF ASSETS

Effective July 1, 1996, the Registrant acquired certain assets of the Gas 
Division of Ateco Automotive Pty. Ltd. ("Ateco") for cash in the amount of 
approximately $6,500,000.  Ateco, a private company in Australia, has 
distributed the Company's gaseous fuel carburetion systems and related 
devices for use with internal combustion engines since approximately 1969.

In order to effectuate the transaction and conduct business in Australia, 
IMPCO Technologies Inc. ("IMPCO") a wholly owned subsidiary of the 
Registrant, established a new Australian operating company, IMPCO 
Technologies Pty. Limited ("IMPCO Ltd."). The assets, which were acquired by 
IMPCO Ltd., consist primarily of receivables, inventory, equipment, a note, 
business goodwill, distribution rights in Australia, and a 50% interest in 
Ateco's sub-distributor.  The amount of the consideration was determined 
through negotiations between Ateco and IMPCO Ltd. 

The purchase price was primarily financed through term loans provided by Bank 
of America NT&SA and its Sydney, Australia branch.  The loans of 
approximately $4,000,000 are three-year loans with five-year amortization
schedules with interest at market rates.  In addition, accounts receivables 
due to IMPCO from Ateco, totaling $1,852,000, were offset against the 
purchase price.  The balance of the purchase price was financed by IMPCO's 
existing line of credit with Bank of America NT&SA.

Impco Ltd. plans to continue the current business of marketing and 
distributing IMPCO's gaseous fuel carburetion systems and related devices in 
Australia and may engage in other related businesses in the future.

Board of Directors
Impco Technologies Pty. Ltd.

We have audited the accompanying balance sheet of the Gas Division of Ateco 
Automotive Pty. Ltd. as of June 30, 1996 and the related statements of 
operations and division equity and cash flows for the year then ended. 
These financial statements are the responsibility of the Division's 
management.  Our responsibility is to express an opinion on these financial
statements based on our audit.  

We conducted our audit in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free of 
material misstatement.  An audit includes examining, on a test basis, evidence 
supporting the amounts and disclosures in the financial statements.  An audit 
also includes assessing the accounting principles used and significant 
estimates made by management, as well as evaluating the overall financial 
statement presentation.  We believe that our audit provides a reasonable basis 
for our opinion.  

In our opinion, the financial statements referred to  above present fairly, in
all material respects, the financial position of the Gas Division of Ateco 
Automotive Pty. Ltd. at June 30, 1996 and the results of its operations and 
its cash flows for the year then ended in conformity with generally accepted 
accounting principles.

NOTE 2:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- ---------------------------------------------------

The financial statements have been prepared in accordance with United States
(U.S.) generally accepted accounting principles and are presented in U.S. 
dollars.

(a)  Depreciation

     Property, plant and equipment is stated on the basis of cost.
     Depreciation is calculated on a straight line basis to write off the
     cost of each item of property, plant and equipment over its expected
     useful life.

(b)  Income Tax

     Notional income tax attributable to the Division income has been
     reflected in the accompanying statement of operations based on the
     Australian income tax rate.  The results of the Division are included in
     Ateco Automotive Pty. Ltd.'s income tax return.  The effective income
     tax rate approximates the Australian statutory rate.  There are no
     significant deferred tax assets or liabilities at June 30, 1996.

     Income tax payable has been adjusted through the divisional equity
     account in the accompanying  balance sheet as the Division is not a
     separate taxable entity.

(c)  Inventories

     Inventories are stated at lower of cost or net realizable value.  Cost
     has been determined under the average cost method.

(d)  Corporate Charges

     The Division is provided with working capital on an as needed basis with
     excess cash remitted to Ateco Automotive Pty. Ltd. on a monthly basis.
     Group administrative expenses are allocated to the Division based on a
     corporate interest charge of eight percent of the Division's monthly
     inventory and debtor balance to compensate Ateco Automotive Pty. Ltd.
     for group management services, legal and other administrative services
     provided.  Management believes this basis of cost allocation is a
     reasonable estimate of services provided.  If the Division were a 
     separate entity, the operating results and financial position might be
     significantly different than presented herein.

     Financial statements prepared in accordance with generally accepted
     accounting principles require management to make estimates and judgments

     The initial amount of the investment in Gas Parts (NSW) Pty. Ltd.("Gas
     Parts"), an associated company, is stated at cost.  The current balance
     has been adjusted for the Division's share of Gas Part's earnings and

            GAS DIVISION OF ATECO AUTOMOTIVE PTY LTD AND SUBSIDIARY

         PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS (UNAUDITED)

Effective July 1, 1996, the registrant acquired certain assets of the Gas 
Division of Ateco Automotive Pty. Ltd. ("Ateco") for cash in the amount of 
approximately $6,500,000.  In order to effectuate the transaction, IMPCO 
Technologies Inc. ("IMPCO Inc.") a wholly owned subsidiary of the Registrant,
established a wholly owned subsidiary in Australia, IMPCO Technologies Pty. 
Limited ("IMPCO Ltd.").  The assets, which were acquired by IMPCO Ltd., 
consist primarily of receivables, inventory, equipment, a note, business 
goodwill, distribution rights in Australia, and a 50% interest in Ateco's 
sub-distributor.

The purchase price was financed through approximately $4,000,000 of term 
loans provided by Bank of America NT&SA and its Sydney Australia branch. 
The term loans are both three-year loans with a five-year amortization 
schedule with interest at market rates.  In addition, accounts receivables due 
to IMPCO Inc. by Ateco, totaling approximately $1,852,000, were also offset
against the purchase price.  The balance of the purchase price was paid 
with proceeds from IMPCO Inc.'s existing line of credit with Bank of 
America NT&SA.

The following pro forma statements have been prepared to illustrate the 
effect of the acquisition, which is being accounted for as a purchase. 
The unaudited pro forma condensed balance sheets combine the balance sheets 
of AirSensors, Inc. and its subsidiaries as of April 30, 1996 and Ateco as of 
June 30, 1996.  The unaudited pro forma condensed income statements combine
the income statements of AirSensors Inc. and its subsidiaries for the year 
ended April 30, 1996 and Ateco for the year ended June 30, 1996.  The pro
forma information is based upon the historical financial statements of the
respective entities while the pro forma adjustments on which they are based
are described in the accompanying notes.

The AirSensors, Inc. unaudited pro forma condensed combined financial 
statements are presented for illustrative purposes only and are not 
necessarily indicative of the consolidated financial position or consolidated
results of operations of AirSensors, Inc. that would have been reported had
the Acquisition occurred on the dates indicated, nor do they represent a
forecast of the consolidated financial position of AirSensors, Inc. at any 
future date or the consolidated results of operations of AirSensors, Inc. at
any future period.  Amounts allocated to assets purchased from Ateco by IMPCO
Ltd. are based on estimated fair values derived from information currently
available.  The purchase price allocation is preliminary and based on 
management's best estimate.

The unaudited pro forma condensed combined financial statements should be 
read in conjunction with the related notes thereto and the historical
consolidated financial statements of AirSensors, Inc. and subsidiaries and
the historical Ateco financial statements.

                           BUSINESS LOAN AGREEMENT

          This Agreement dated as of 25 June, 1996, is between Bank of America
National Trust and Savings Association (the "Bank"), IMPCO Technologies, Inc.
(the "Borrower"), and AirSensors, Inc. (the "Guarantor").

1.   FACILITY NO. 1:  LINE OF CREDIT AMOUNT AND TERMS

          1.1   LINE OF CREDIT AMOUNT.

                (a)  During the availability period described below, the Bank
     will provide a line of credit ("Facility No. 1") to the Borrower.  The
     amount of the line of credit (the "Facility No. 1 Commitment") is Eight
     Million Dollars ($8,000,000).

                (b)  This is a revolving line of credit with a within line
     facility for letters of credit.  During the availability period, the
     Borrower may repay principal amounts and reborrow them.

                (c)  The Borrower agrees not to permit the outstanding
     principal balance of the line of credit plus the outstanding amounts of
     any letters of credit, including amounts drawn on letters of credit and
     not yet reimbursed, to exceed the Facility No. 1 Commitment.

          1.2   AVAILABILITY PERIOD.  The line of credit is available between
the date of this Agreement and August 31, 1998 (the "Expiration Date") unless
the Borrower is in default.

          1.3   INTEREST RATE.

                (a)  Unless the Borrower elects an optional interest rate as
     described below, the interest rate is the Bank's Reference Rate.

                (b)  The Reference Rate is the rate of interest publicly
      announced from time to time by the Bank in San Francisco, California,
      as its Reference Rate.  The Reference Rate is set by the Bank based on
      various factors, including the Bank's costs and desired return, general
      economic conditions and other factors, and is used as a reference point
      for pricing some loans.  The Bank may price loans to its customers at,
      above, or below the Reference Rate.  Any change in the Reference Rate
      shall take effect at the opening of business on the day specified in
      the public announcement of a change in the Bank's Reference Rate.

     unpaid interest or other charges outstanding under this line of credit
     no later than the Expiration Date.  Any amount bearing interest at an
     optional interest rate (as described below) may be repaid at the end of
     the applicable interest period, which shall be no later than the
     Expiration Date.

rate listed below for this Facility No. 1 during interest periods agreed to by
the Bank and the Borrower.  The optional interest rate shall be subject to the

     Cayman Rate Portion if any of the following described events has
     occurred and is continuing:

                                      -6-

                 (b)  Each LIBOR Rate portion will be for an amount not less
     than Five Hundred Thousand Dollars ($500,000).

                 (c)  The "LIBOR Rate" means the interest rate determined by
     the following formula, rounded upward to the nearest 1/100 of one
     percent.  (All amounts in the calculation will be determined by the Bank
     as of the first day of the interest period.)

           LIBOR Rate =     London Inter-Bank Offered Rate
                            ------------------------------
                             (1.00 - Reserve Percentage)

          11:00 a.m. London time two (2) London Banking Days before the
          commencement of the interest period.  A "London Banking Day" is a
          day on which the Bank's London Branch is open for business and

          rounded upward to the nearest 1/100 of one percent.  The percentage

          limited to, marginal, emergency, supplemental, special, and other
          reserve percentages.

     portion no later than 12:00 noon San Francisco time on the LIBOR Banking

     interest at the LIBOR Rate will not be converted to a different rate
     during its interest period.

                 (g)  Each prepayment of a LIBOR Rate portion, whether
     voluntary, by reason of acceleration or otherwise, will be accompanied by

          payable during the interest period on the amount prepaid had it not
          been prepaid, exceeds

                     (ii)  the interest which would have been recoverable by
          the Bank by placing the amount prepaid on deposit in the domestic
          certificate of deposit market, the eurodollar deposit market, or
          other appropriate money market selected by the Bank, for a period
          starting on the date on which it was prepaid and ending on the last
          day of the interest period for such portion (or the scheduled
          payment date for the amount prepaid, if earlier).

          not available in the London inter-bank market; or

                     (ii)  the LIBOR Rate does not accurately reflect the cost
          of a LIBOR Rate portion.

5.  FEES, EXPENSES AND COSTS

          5.1  UNUSED COMMITMENT FEE.  The Borrower agrees to pay a fee on any

7.  DISBURSEMENTS, PAYMENTS AND COSTS

          7.1  REQUESTS FOR CREDIT.  Each request for an extension of credit
will be made in writing in a manner acceptable to the Bank, or by another
means acceptable to the Bank.

          7.2  DISBURSEMENTS AND PAYMENTS.  Each disbursement by the Bank and
each payment by the Borrower will be:

                 (a)  made at the Bank's branch (or other location) selected

                 (b)  made for the account of the Bank's branch selected by
     the Bank from time to time;

     of funds selected by the Bank;

                 (d)  evidenced by records kept by the Bank.  In addition, the

                                      -10-
<PAGE>

                 (b)  Advances will be deposited in and repayments will be
     withdrawn from the Borrower's account number 12331-16650, or such other
     of the Borrower's accounts with the Bank as designated in writing by the
     Borrower.

                 (c)  The Borrower indemnifies and excuses the Bank (including
     its officers, employees, and agents) from all liability, loss, and costs
     in connection with any act resulting from telephone or telefax
     instructions it reasonably believes are made by any individual authorized
     by the Borrower to give such instructions.  This indemnity and excuse
     will survive this Agreement's termination.

          7.4  DIRECT DEBIT (PRE-BILLING).

                 (a)  The Borrower agrees that the Bank will debit the
     Borrower's deposit account number 12331-16650, or such other of the
     Borrower's accounts with the Bank as designated in writing by the
     Borrower (the "Designated Account") on the date each payment of principal
     and interest and any fees from the Borrower becomes due (the "Due Date").
     If the Due Date is not a banking day, the Designated Account will be
     debited on the next banking day.

                 (b)  Approximately 10 days prior to each Due Date, the Bank
     will mail to the Borrower a statement of the amounts that will be due on
     that Due Date (the "Billed Amount").  The calculation will be made on the
     assumption that no new extensions of credit or payments will be made
     between the date of the billing statement and the Due Date, and that
     there will be no changes in the applicable interest rate.

                 (c)  The Bank will debit the Designated Account for the
     Billed Amount, regardless of the actual amount due on that date (the
     "Accrued Amount").  If the Billed Amount debited to the Designated
     Account differs from the Accrued Amount, the discrepancy will be treated
     as follows:

                      (i)  If the Billed Amount is less than the Accrued
          Amount, the Billed Amount for the following Due Date will be
          increased by the amount of the discrepancy.  The Borrower will not
          be in default by reason of any such discrepancy.

                     (ii)  If the Billed Amount is more than the Accrued
          Amount, the Billed Amount for the following Due Date will be
          decreased by the amount of the discrepancy.

     Regardless of any such discrepancy, interest will continue to accrue
     based on the actual amount of principal outstanding without compounding.
     The Bank will not pay the Borrower interest on any overpayment.

                 (d)  The Borrower will maintain sufficient funds in the
     Designated Account to cover each debit.  If there are insufficient funds
     in the Designated Account on the date the Bank enters any debit
     authorized by this Agreement, the debit will be reversed.

          7.5  BANKING DAYS.  Unless otherwise provided in this Agreement, a
banking day is a day other than a Saturday or a Sunday on which the Bank is
open for business in California.  For amounts bearing interest at an offshore
rate (if any), a banking day is a day other than a Saturday or a Sunday on
which the Bank is open for business in California and dealing in offshore
dollars.  All payments and disbursements which would be due on a day which is
not a banking day will be due on the next banking day.  All payments received
on a day which is not a banking day will be applied to the credit on the next
banking day.  For amounts bearing interest at a LIBOR Rate, a banking day is a
day other than a Saturday or a Sunday on which the Bank is open for business
in California, New York and London and dealing in offshore dollars.

          7.6  TAXES.  If any payments to the Bank under this Agreement are
made from outside the United States, the Borrower will not deduct any foreign
taxes from any payments it makes to the Bank.  If any such taxes are imposed
on any payments made by the Borrower (including payments under this
paragraph), the Borrower will pay the taxes and will also pay to the Bank, at
the time interest is paid, any additional amount which the Bank specifies as
necessary to preserve the after-tax yield the Bank would have received if such
taxes had not been imposed.  The Borrower will confirm that it has paid the
taxes by giving the Bank official tax receipts (or notarized copies) within 30
days after the due date.

          7.7  ADDITIONAL COSTS.  The Borrower will pay the Bank, on demand,
for the Bank's costs or losses arising from any statute or regulation, or any
request or requirement of a regulatory agency which is applicable to all
national banks or a class of all national banks.  The costs and losses will be
allocated to the loan in a manner determined by the Bank, using any reasonable
method.  The costs include the following:

                 (a)  any reserve or deposit requirements; and

                 (b)  any capital requirements relating to the Bank's assets
     and commitments for credit.

          7.8  INTEREST CALCULATION.  Except as otherwise stated in this
Agreement, all interest and fees, if any, will be computed on the basis of a
360-day year and the actual number of days elapsed.  This results in more
interest or a higher fee than if a 365-day year is used.

                                      -12-
<PAGE>

          7.9  DEFAULT RATE.  Upon the occurrence and during the continuation
of any default under this Agreement, principal amounts outstanding under this
Agreement will at the option of the Bank bear interest at a rate which is two
and one-half (2.50) percentage points higher than the rate of interest
otherwise provided under this Agreement.  This will not constitute a waiver of
any default.  Installments of principal which are not paid when due under this
Agreement shall continue to bear interest until paid.  Any interest, fees or
costs which are not paid when due shall bear interest at the Bank's Reference
Rate plus three (3.0) percentage points.  This may result in compounding of
interest.

apply whether the hazardous substance is on, under or about the Borrower's or
the Guarantor's property or operations or property leased to the Borrower or
the Guarantor.  The indemnity includes but is not limited to attorneys' fees
(including the reasonable estimate of the allocated cost of in-house counsel
and staff).  The indemnity extends to the Bank, its parent, subsidiaries and
all of their directors, officers, employees, agents, successors, attorneys and
assigns.  For these purposes, the term "hazardous substances" means any
substance which is or becomes designated as "hazardous" or "toxic" under any
federal, state or local law.  This indemnity will survive repayment of the
Borrower's and the Guarantor's obligations to the Bank.

after the filing; provided, however, that the Bank will not

                                      -22-
<PAGE>

be obligated to extend any additional credit to the Borrower during that
period.

          13.10  CROSS-DEFAULT.  Any default occurs under any agreement in
connection with any credit the Borrower or the Guarantor has obtained from
anyone else or which the Borrower or the Guarantor has guaranteed and such

<PAGE>

being remedied, the breach will not be considered an event of default under
this Agreement for a period of thirty (30) days after the date on which the
Bank gives written notice of the breach to the Borrower; provided, however,
that the Bank will not be obligated to extend any additional credit to the
Borrower during that period.

participation is sold or the loan is assigned, the purchaser will have the
right of set-off against the Borrower.

          14.4  ARBITRATION.

                 (a)  This paragraph concerns the resolution of any
     controversies or claims between the Borrower and the Bank, including but
     not limited to those that arise from:

                      (i)  This Agreement (including any renewals, extensions
          or modifications of this Agreement);

                     (ii)  Any document, agreement or procedure related to or
          delivered in connection with this Agreement;

                    (iii)  Any violation of this Agreement; or

                     (iv)  Any claims for damages resulting from any business
          conducted between the Borrower and the Bank, including claims for
          injury to persons, property or business interests (torts).

                 (b)  At the request of the Borrower or the Bank, any such
     controversies or claims will be settled by arbitration in accordance with
     the United States Arbitration Act.  The United States Arbitration Act
     will apply even though this Agreement provides that it is governed by
     California law.

                                      -24-
<PAGE>

                 (c)  Arbitration proceedings will be administered by the
     American Arbitration Association and will be subject to its commercial
     rules of arbitration.

                 (d)  For purposes of the application of the statute of
     limitations, the filing of an arbitration pursuant to this paragraph is
     the equivalent of the filing of a lawsuit, and any claim or controversy
     which may be arbitrated under this paragraph is subject to any applicable
     statute of limitations.  The arbitrators will have the authority to
     decide whether any such claim or controversy is barred by the statute of
     limitations and, if so, to dismiss the arbitration on that basis.

                 (e)  If there is a dispute as to whether an issue is
     arbitrable, the arbitrators will have the authority to resolve any such
     dispute.

                 (f)  The decision that results from an arbitration proceeding
     may be submitted to any authorized court of law to be confirmed and
     enforced.

                 (g)  The procedure described above will not apply if the
     controversy or claim, at the time of the proposed submission to
     arbitration, arises from or relates to an obligation to the Bank secured
     by real property located in California.  In this case, both the Borrower
     and the Bank must consent to submission of the claim or controversy to
     arbitration.  If both parties do not consent to arbitration, the
     controversy or claim will be settled as follows:

                      (i)  The Borrower and the Bank will designate a referee
          (or a panel of referees) selected under the auspices of the American
          Arbitration Association in the same manner as arbitrators are
          selected in Association-sponsored proceedings;

                     (ii)  The designated referee (or the panel of referees)
          will be appointed by a court as provided in California Code of Civil
          Procedure Section 638 and the following related sections;

                    (iii)  The referee (or the presiding referee of the panel)
          will be an active attorney or a retired judge; and

                     (iv)  The award that results from the decision of the
          referee (or the panel) will be entered as a judgment in the court
          that appointed the referee, in accordance with the provisions of
          California Code of Civil Procedure Sections 644 and 645.

                 (h)  This provision does not limit the right of the Borrower
     or the Bank to:

                                      -25-
<PAGE>

                      (i)  exercise self-help remedies such as setoff;

                     (ii)  foreclose against or sell any real or personal
          property collateral; or

                    (iii)  act in a court of law, before, during or after the
          arbitration proceeding to obtain:

                         (A)  an interim remedy; and/or

                         (B)  additional or supplementary remedies.

                 (i)  The pursuit of or a successful action for interim,
     additional or supplementary remedies, or the filing of a court action,
     does not constitute a waiver of the right of the Borrower or the Bank,
     including the suing party, to submit the controversy or claim to
     arbitration if the other party contests the lawsuit.  However, if the
     controversy or claim arises from or relates to an obligation to the Bank
     which is secured by real property located in California at the time of
     the proposed submission to arbitration, this right is limited according
     to the provision above requiring the consent of both the Borrower and the
     Bank to seek resolution through arbitration.

                 (j)  If the Bank forecloses against any real property
     securing this Agreement, the Bank has the option to exercise the power of
     sale under the deed of trust or mortgage, or to proceed by judicial
     foreclosure.

          14.5  SEVERABILITY; WAIVERS.  If any part of this Agreement is not
enforceable, the rest of the Agreement may be enforced.  The Bank retains all
rights, even if it makes a loan after default.  If the Bank waives a default,
it may enforce a later default.  Any consent or waiver under this Agreement
must be in writing.

          14.6  ADMINISTRATION COSTS.  The Borrower and the Guarantor shall
pay the Bank for all reasonable costs incurred by the Bank in connection with
administering this Agreement.

          14.7  ATTORNEYS' FEES.  The Borrower and the Guarantor shall
reimburse the Bank for any reasonable costs and attorneys' fees incurred by
the Bank in connection with the enforcement or preservation of any rights or
remedies under this Agreement and any other documents executed in connection
with this Agreement, and including any amendment, waiver, "workout" or
restructuring under this Agreement.  In the event of a lawsuit or arbitration
proceeding, the prevailing party is entitled to recover costs and reasonable
attorneys' fees incurred in connection with the lawsuit or arbitration
proceeding, as determined by the court or arbitrator.  In the event that any

                                      -26-
<PAGE>

case is commenced by or against the Borrower under the Bankruptcy Code (Title
11, United States Code) or any similar or successor statute, the Bank is
entitled to recover costs and reasonable attorneys' fees incurred by the Bank
related to the preservation, protection, or enforcement of any rights of the
Bank in such a case.  As used in this paragraph, "attorneys' fees" includes
the allocated costs of the Bank's in-house counsel.

          14.8  ONE AGREEMENT.  This Agreement and any related security or
other agreements required by this Agreement, collectively:

                 (a)  represent the sum of the understandings and agreements
     between the Bank and the Borrower concerning this credit;

                 (b)  replace any prior oral or written agreements between the
     Bank and the Borrower concerning this credit; and

                 (c)  are intended by the Bank and the Borrower as the final,
     complete and exclusive statement of the terms agreed to by them.

In the event of any conflict between this Agreement and any other agreements
required by this Agreement, this Agreement will prevail.

          14.9  INDEMNIFICATION.  The Borrower and the Guarantor will
indemnify and hold the Bank harmless from any loss, liability, damages,
judgments, and costs of any kind relating to or arising directly or indirectly
out of (a) this Agreement or any document required hereunder, (b) any credit
extended or committed by the Bank to the Borrower hereunder, and (c) any
litigation or proceeding related to or arising out of this Agreement, any such
document, or any such credit.  This indemnity includes but is not limited to
attorneys' fees (including the allocated cost of in-house counsel).  This
indemnity extends to the Bank, its parent, subsidiaries and all of their
directors, officers, employees, agents, successors, attorneys, and assigns.
This indemnity will survive repayment of the Borrower's and the Guarantor's
obligations to the Bank.  All sums due to the Bank hereunder shall be
obligations of the Borrower and the Guarantor, due and payable immediately
without demand.

          14.10  NOTICES.  All notices required under this Agreement shall be
personally delivered or sent by first class mail, postage prepaid, to the

as the Bank, the Guarantor or the Borrower may specify from time to time in

separate counterparts each of which, when so executed, shall be deemed an
original but all such counterparts shall constitute but one and the same
agreement.

          14.13  PRIOR AGREEMENT SUPERSEDED.  This Agreement supersedes the
Business Loan Agreement entered into as of September 28, 1994 among the Bank,

       Bank of Australia it becomes unlawful for the Bank to maintain or give
       effect to any of its obligations, rights, powers or remedies under
       this Agreement or the Support, then the Bank may cancel any or all the
       Facilities by notice to the Borrower.  No further use may then be made
       of those Facilities and the Borrower shall immediately prepay to the
       Bank all moneys owing under this Agreement in respect of those
       Facilities including any accrued interest and fees.

10.    RESERVE REQUIREMENTS

       of the Facilities or relating in any way to funding or renewing any,
       all or any part of the Facilities where those reserves, special
       deposits or other costs arise out of any act of any governmental
       authority after the date of this Agreement.  The protection of this
       paragraph shall apply to any act by the Reserve Bank of Australia, any
       government, governmental agency or department having authority over
       the Bank but shall not extend to any cost incurred by the Bank in
       consequence of any default on its behalf.  The protection of this
       paragraph shall apply to compliance by the Bank with restraints,

<PAGE>11

       guidelines or policies not having the force of law but with which it
       is in practice necessary for the Bank and institutions similarly
       situated to comply, and shall apply irrespective of any possible
       contention of invalidity or nonapplicability.



10.2   If the Bank makes a demand under clause 1O.1 or gives any notice under
       clause 10.3, the Borrower may prepay all amounts advanced by the Bank
       under the Facilities or any portion affected by any matter referred to
       in this clause 10 (so long as it pays all interest accrued to the date
       of the prepayment on the amount prepaid) upon giving the Bank a
       minimum of 14 days' written notice (which shall be irrevocable).

10.3   The Bank shall give to the Borrower as much advance notice as may be
       reasonably practicable of circumstances giving rise to a claim for
       payment under clause 10.1 provided that the Bank shall not be liable
       for any failure to give such notice.

10.4   The determination by the Bank of the relevant costs incurred under
       this clause 10 shall, in the absence of manifest error, be conclusive
       and binding on the Borrower.

       (a)  to rely upon any facsimile transmission received by the Bank

            on the Bank's part as to the source of the transmission or the
            identity of the person(s) making or purporting to make the
            communication and regardless of the circumstances prevailing at
            the time of such transmission or communication so long as any
            signature appearing in the transmission appears on reasonable
            examination to correspond with the specimen signature of a person
            it reasonably believes to be authorised to make that
            transmission;

       (b)  to treat these transmissions as fully authorised by and binding
            upon the Borrower and the Bank,

       (c)  to take such steps in connection with or in reliance upon these

            whether these communications include instructions to pay money or
            otherwise to debit or credit any account, or relates to the
            disposition of any money, securities or documents, or purports to

       acknowledges that the Bank may disclose from time to time Customer
       Information to other offices and branches of the Bank and to the
       Bank's Subsidiaries and affiliates.  The Borrower also consents to the
       disclosure of Customer Information by the Bank, or any of its
       Subsidiaries or affiliates:



       (i)   at the request of any governmental, regulatory or other similar
             agency or authority having jurisdiction over the Bank or any of
             its Subsidiaries or affiliates;

       (ii)  pursuant to any subpoena or other court process, or to the
             extent required in connection with any litigation between the
             Bank, Subsidiary or affiliate and the Borrower, provided that
             the disclosure is subject to an appropriate protective order if
             such protective order is available;

       (iii) where the Customer Information is in the public domain;

       (iv)  to its legal advisers and its consultants so long as it advises
             them of the confidential nature of the information or documents
             or that nature is clear from the circumstances of the

       paid pursuant to a judgment) the Borrower shall be discharged from its
       obligations only to the extent of the amount of the currency in which
       the obligation was denominated (as the Bank is able to purchase in
       accordance with its usual practice, using the amount of currency
       received) after deduction of any transaction costs in making the
       purchase.

                  Authorisations; and

            (ii)  circumstances which may give rise to a claim, to a
