                                ensure that you pay no more than you would have
                                paid in taxes on covered income than had you not
                                been assigned overseas. The tax liability you
                                incur during your overseas assignment should be
                                the same as that of a domestic employee under
                                similar economic circumstances. You will be
                                reimbursed for any U.S. or foreign taxes that
                                you are required to pay beyond the U.S. and
                                Florida taxes you would have incurred on your
                                base salary, bonus (if any), imputed income from
                                group life insurance, and any other covered
                                income had you not accepted this overseas
                                assignment.

                                While you are on assignment, you will pay a
                                hypothetical tax in lieu of actual tax
                                liabilities. The hypothetical tax is intended to
                                be representative of your tax responsibilities
                                while on assignment. We will have Ernst & Young
                                calculate the amount to be withheld.

                                years. This period will not be extended beyond
                                approximately three (3) years except by the
                                mutual agreement of the parties. If an extension
                                is agreed to by the parties, you and the Company
                                will determine if the terms and conditions in
                                this contract will continue to apply or if the
                                Company will be converting you to a local
                                package.

                                During your assignment with JHINV, you shall
                                continue to remain an at-will employee. Thus,
                                notwithstanding the term of this assignment,
                                either you or the Company can terminate the
                                employment relationship at any time and for any
                                reason. However, in the event that you wish to
                                terminate this assignment, we request that you
                                provide your manager with one (1) months' notice

                                courtesy with respect to this assignment,
                                although it reserves the right to pay you one
                                month's salary in lieu of notice. If your
                                assignment is terminated by JH for breach of

                                defined below, your employment with the Company

                                assignment and you will not be entitled to
                                repatriation benefits, reinstatement or
                                severance.

                                For purposes of this letter, you will be in
                                breach of conditions applying to your employment
                                for engaging in unlawful harassment or
                                discrimination, substance abuse, theft, or
                                dishonesty; falsification of any Company

                                action by you which has a material detrimental
                                effect on the Company's reputation or business;
                                insubordination; your failure or inability to
                                perform any assigned duties (which are in
                                keeping with duties normally performed by a
                                General Counsel) after reasonable notice from
                                the Company of such failure or inability; or
                                your conviction (including any plea of guilty or
                                no contest) for any criminal act that impairs

                                agreement.

                                If you are terminated by the Company prior to
                                the completion of this assignment for breach of
                                conditions applying to your employment, or you
                                voluntarily terminate your assignment before the
                                end of its term, you agree to pay back all
                                relocation costs (pro-rated), which the Company
                                has paid to you or for you associated with your
                                relocation from the US to Amsterdam.

30% TAX RULING:                 1) If and to the extent that you will be
                                eligible for a tax-free reimbursement for
                                extra-territorial expenses based on Article 9 of
                                the 1965 Dutch Wage Tax Implementation Decree
                                ('Uitvoeringsbesluit loonbelasting 1965'), it
                                will be agreed that the remuneration for present
                                employment ('loon uit tegenwoordige
                                dienstbetrekking') as agreed with you will be
                                reduced for labor law purposes in such a way
                                that 100/70 of the thus agreed remuneration for
                                present employment is equal to the originally
                                agreed remuneration for present employment.

                                2) If and to the extent that part 1 is applied,
                                you shall receive from the company a
                                reimbursement for extra-territorial expenses
                                equal to 30/70 of the thus agreed remuneration
                                for present employment.

                                3) You are aware of the fact that adjustment of
                                the agreed remuneration pursuant to part 1 may
                                in view of the applicable regulations have
                                consequences for all remuneration - related
                                benefits and payments.

                                4) The "agreed remuneration for present
                                employment " as described in part 1 concerns all
                                the actual to-be-paid or to-be-provided
                                remuneration for present employment as described
                                in the 1964 Dutch Wage Tax Act and the
                                provisions based on it.

                                If the Dutch tax authorities publish additional
                                guidelines regarding the 30% - facility, this
                                agreement will be adjusted accordingly, if
                                necessary.

                                                                               4

potential customers), sources of supply, processes, plans, materials, pricing
information, internal memoranda, marketing plans, internal policies, and
products and services which may be developed from time to time by the Group and

information of the Group to enter the public domain.

                                                                               4

6.01(b), 6.02(b), and 6.03(c) for a period of at least two (2) years, and up to
four (4) years at the Company's discretion (assuming exercise of the Company's
rights under 7.01(b)), after the termination of this Agreement, directly or
indirectly, in any capacity, engage or participate in, or become employed by or
render advisory or consulting or other services in connection with any
Prohibited Business as defined in Section 5.02(c).

            (b) The Executive agrees that the Executive shall not during the
Executive's employment with the Company, and, in accordance with Sections
6.01(b), 6.02(b), and 6.03(c) for a period of at least two years, and up to four
(4) years at the Company's discretion (assuming exercise of the Company's rights
under 7.01(b)), after the termination of this Agreement, make any financial
investment, whether in the form of equity or debt, or own any interest, directly
or indirectly, in any Prohibited Business. Nothing in this Section 5.02(b)
shall, however, restrict the Executive from making any investment in any company
whose stock is listed on a national securities exchange; provided that (i) such
investment does not give the Executive the right or ability to control or
influence the policy decisions of any Prohibited Business, and (ii) such
investment does not create a conflict of interest between the Executive's duties
hereunder and the Executive's interest in such investment.

            (c) For purposes of this Section 5.02, "Prohibited Business" shall
be defined as the business of:

                  (i)   marketing or selling of fiber cement products, where the
                        marketing or selling of such products is a principal
                        activity of the business;

                  (ii)  manufacturing or processing fiber cement products;

                  (iii) building, assembling, operating or maintaining plant and
                        equipment, where that plant and equipment is particular
                        to the manufacturing or processing of fiber cement
                        products;

                  (iv)  manufacturing or processing raw materials for fiber
                        cement products where that manufacturing or processing
                        is particular to the raw material used in fiber cement
                        products;

                  (v)   research or development activities relating to Section
                        5.02(c)(i)-(iv); and

and any branch, office or operation thereof, which is a competitor of the
Company or which has established or seeks to establish contact, in whatever form
(including, but not limited to solicitation of sales, or the receipt or
submission of bids), with any entity who is at any time a client, customer or
supplier of the Company (including but not limited to all subdivisions of the
federal government.)

                                                                               5

<PAGE>

      5.03 Non-Solicitation. From the date hereof until at least two (2) years
and up to four (4) years at the Company's discretion after the Executive's
termination of employment with the Company, the Executive shall not, directly or
indirectly (a) encourage any employee or supplier of the Group or any of their
successors in interest to leave his or her employment with the Group or any of
their successors in interest, (b) employ, hire, solicit or cause to be employed,
hired or solicited (other than by the Group or any of their successors in
interest), or encourage others to employ or hire any person who within at least
two (2) years, and up to four (4) years at the Company's discretion, prior
thereto was employed by the Group or any of their successors in interest, or (c)
establish a business with, or encourage others to establish a business with, any
person who within at least two (2) years, and up to four (4) years at the
Company's discretion, prior thereto was an employee or supplier of the Group or
any of their successors in interest.

      5.04 Disclosure of Employee-Created Trade Secrets Confidential and
Proprietary Business Information. The Executive agrees to promptly disclose to
the Company all Protected Information developed in whole or in part by the
Executive during the Executive's employment with the Company and which relates
to the Group's business. Such Protected Information is, and shall remain, the
exclusive property of the Company. All writings created during the Executive's
employment with the Company (excluding writings unrelated to the Company's
business) are considered to be "works-for-hire" for the benefit of the Group and
the Company shall own all rights in such writings.

      5.05 Survival of Undertakings and Injunctive Relief

            (a) The provisions of Sections 5.01, 5.02, 5.03 and 5.04 of this
Agreement shall survive both the termination of the Executive's employment with
the Company and the termination of this Agreement irrespective of the reasons
for such termination.

            (b) The Executive acknowledges and agrees that the restrictions
imposed upon the Executive by Sections 5.01, 5.02, 5.03 and 5.04 of this
Agreement and the purpose of such restrictions are reasonable and are designed
to protect the Protected Information and the continued success of the Company
without unduly restricting the Executive's future employment by others.
Furthermore, the Executive acknowledges that, in view of the Protected
Information which the Executive has or will acquire or has or will have access
to and in view of the necessity of the restrictions contained in Sections 5.01,
5.02, 5.03 and 5.04, any violation of any provision of Sections 5.01, 5.02, 5.03
and 5.04 hereof would cause irreparable injury to the Company and its successors
in interest with respect to the resulting disruption in their operations. By
reason of the foregoing the Executive consents and agrees that if the Executive
violates any of the provisions of Sections 5.01, 5.02, 5.03 or 5.04 of this
Agreement, the Company and its successors in interest as the case may be, shall
be entitled, in addition to any other remedies that they may have, including
money damages, to an injunction to be issued by a court of competent
jurisdiction, restraining the Executive from committing or continuing any
violation of such Sections of this Agreement.

      In the event of any such violation of Sections 5.01, 5.02, 5.03 and 5.04
of this Agreement, the Executive further agrees that the time periods set forth
in such Sections shall be extended by the period of such violation.

                                                                               6

                                   TERMINATION

      6.01 Termination of Employment by Voluntary Resignation /Death
/Disability.

            (a) The Executive's employment under this Agreement may be
terminated:

                  (i) Upon voluntary resignation by the Executive in accordance
with the notification requirement provided in Article IX;

                  (ii) Upon the death of the Executive, this Agreement and the
Executive's employment hereunder shall terminate immediately and without notice
by the Company; or

                  (iii) In the event of the inability of the Executive to
perform his duties or responsibilities thereunder, as a result of a Permanent
Disability (as defined below) upon written notice by the Company. A "Permanent
Disability" occurs when for a period of ninety (90) consecutive calendar days,
or an aggregate of one hundred twenty (120) calendar days during any calendar
year (whether or not consecutive) the Executive is unable to perform his duties
or responsibilities hereunder as a result of a mental or physical ailment or
incapacity. Upon the occurrence of a Permanent Disability, the Company will
evaluate the Executive's condition and determine whether or not to send written
notice of such Executive's termination.

            (b) Upon termination pursuant to this Section 6.01(a)(i), the
Executive shall not be entitled to payment of any compensation other than salary
under this Agreement earned up to the date of such termination, any accrued but
unpaid vacation days, and any stock options, warrants or similar rights which
have vested at the date of such termination. The Company and the Executive agree
that the Company shall continue to pay the Executive his Annual Base Salary, in
accordance with the Company's normal practices for other senior executives, for
two (2) years after the Executive's voluntary resignation, and the Executive
agrees not to violate the provisions of Section 5.02 for an equivalent period.

            (c) Upon termination pursuant to this Section 6.01(a)(ii) above, the
Company shall pay or grant, to such person as the Executive designates in a
notice filed with the Company, or, if no such person shall be designated, to the
Executive's estate as a lump sum death benefit, an amount equal to any
compensation under this Agreement earned up to the date of such termination,
including salary and any accrued but unpaid vacation days. In addition, any
stock options or warrants which have vested at the time such termination will be
exercisable by the Executive's estate in accordance with the Company's Equity
Incentive Plan. The Executive's designated beneficiary or the executor of the
Executive's estate, as the case may be, shall accept the payment provided for in
this Paragraph 6.01(c) in full discharge and release of the Company of and from
any further obligations under this Agreement.

            (d) Upon termination pursuant to Section 6.01(a)(iii) above, the
Executive shall be entitled to the benefit of disability or other relevant
insurance or benefits provided pursuant to Section 4.02 above. The Executive
shall not be entitled to payment of any

                                                                               7

<PAGE>

compensation other than salary under this Agreement earned up to the date of
such termination, any accrued but unpaid vacation days, and any stock options,
warrants or similar rights which have vested at the date of such termination.
The Company, in its sole and absolute discretion, may decide to continue to pay
the Executive his Annual Base Salary, in accordance with the Company's normal
practices for other senior executives, for two (2) years after the Executive's
voluntary resignation, in return for the Executive not violating the provisions
of Section 5.02 for an equivalent period and the Executive's execution, without
revocation, of a Company Release of Claims upon the effective date of the
termination of the Executive's employment.

      6.02 Termination for Cause. (a) The Company may terminate the Executive's
employment for Cause by giving the Executive written notice of such termination.
For purposes of this Agreement, "Cause" for termination shall mean:

                  (i) the willful failure or refusal to carry out the reasonable
directions of the Chief Executive Officer or Board of Directors, which
directions are consistent with the Executive's duties as set forth under this
Agreement;

                  (ii) a willful act by the Executive that constitutes gross
negligence in the performance of the Executive's duties under this Agreement and
which materially injures the Company. No act, or failure to act, by the
Executive shall be considered "willful" unless committed without good faith and
without a reasonable belief that the act or omission was in the Company's best
interest; or

                  (iii) a conviction for a violation of a state or federal
criminal law involving the commission of a felony or other crime involving moral
turpitude.

            (b) Upon termination for Cause, the Executive shall not be entitled
to payment of any compensation other than salary under this Agreement earned up
to the date of such termination, any accrued but unpaid vacation days, and any
stock options, warrants or similar rights which have vested at the date of such
termination. The Company and the Executive agree that the Company shall continue
to pay the Executive his Annual Base Salary, in accordance with the Company's
normal practices for other senior executives, for two (2) years after such
termination for Cause, and the Executive agrees not to violate the provisions of
Section 5.02 for an equivalent period and the Executive's execution, without
revocation, of a Company Release of Claims upon the effective date of the
termination of the Executive's employment.

      6.03 Termination Without Cause or Termination by Executive for Good
Reason. Should the Executive's employment be terminated for a reason other than
as specifically set forth in Sections 6.01 or 6.02 above, whether terminated by
the Company or terminated by the Executive for Good Reason (as defined below):

            (a) the Company shall pay the Executive an amount equal to 1.5 times
the Annual Base Salary applying as at the date of termination, paid in
accordance with Section 6.03(c) below.

                                                                               8

<PAGE>

            (b) the Company shall pay the Executive an amount equal to 1.5 times
the Average Annual Bonus actually paid to the Executive in accordance with
Section 6.03(c) below. For purposes of this Section 6.03, Average Annual Bonus
shall mean the aggregate Annual Bonus actually paid to the Executive by the
Company, including the bonus bank amounts actually paid out to the Executive,
over the last three years immediately preceding the year of such termination
divided by three.

            (c) the Company shall pay the amounts specified in each of Sections
6.03(a) and (b) above in monthly installments, in accordance with the Company's
normal payroll practices for other senior executives, for the period of eighteen
months following such termination, in return for the Executive's execution,
without revocation, of a Company Release of Claims upon the effective date of
the termination of the Executive's employment. In addition, the Company and the
Executive agree that the Company shall continue to pay the Executive additional
amounts equal to his Annual Base Salary as of the date of termination of
employment in accordance with the Company's normal practices for other senior
executives, for up to two (2) years following the Executive's termination, and
the Executive agrees not to violate the provisions of Section 5.02 above for an
equivalent period and the Executive's execution, without revocation, of a
Company Release of Claims at that time.

            (d) all of the stock options, warrants, retirement benefits and
other similar rights, if any, granted by the Company to the Executive which are
vested at the date of the termination of the Executive's employment shall remain
vested. All stock options that will vest between the date of such termination of
employment and the completion of the Consulting Agreement addressed in Article
VII of the Agreement (or violation of Section 5.02 above if that occurs), will
continue to vest on the vest dates stipulated in the grant document. All stock
options unvested as of the completion of the Consulting Agreement addressed in
Article VII of the Agreement (or violation of Section 5.02 above if that occurs)
will immediately expire. All stock options vested as of the completion of the
Consulting Agreement addressed in Article VII of the Agreement (or violation of
Section 5.02 above if that occurs) will remain exercisable until the earlier of
(i) the date such Stock Options would expire in accordance with their terms, and
(ii) 90 days after the date of completion of the Consulting Agreement and/or
violation of Section 5.02 above.

            (e) all health and medical benefits shall continue for the remainder
of the term of this Agreement; and the Company will pay the Executive's premium
for continued coverage for medical, dental and vision benefits, if applicable,
under the Consolidated Omnibus Budget Reconciliation Act of 1986, as amended
("COBRA") for himself and, if applicable, his covered dependents for up to
eighteen months following the date of the termination of Executive's employment,
in accordance with the provisions of COBRA, for a period of up to eighteen
months following the termination of the Executive's employment.

                                                                               9

<PAGE>
            The term "Good Reason," in connection with the termination by the
Executive of his employment with the Company shall mean:

            (i) A diminution in the responsibilities, title or office of the
Executive such that he does not serve as an executive officer of the Company
(which diminution was not for Cause or the result of the Executive's
disability); or

            (ii) A reduction by the Company in the Executive's Annual Base
Salary to less than (a) $307,000, or (b) the Executive's Annual Base Salary at
the time of such reduction.

      6.04 No Mitigation. The Executive shall not be required to mitigate the
amount of any payment provided for in Section 6.03 above by seeking other
employment or otherwise, nor shall the amount of any payment provided for in
Section 6.03 be reduced by any compensation earned by the Executive as a result
of employment by another company, self-employment or otherwise.

                                   ARTICLE VII
                       POST-TERMINATION CONSULTING PERIOD

      7.01  In addition to the matters set forth in Article VI above, upon the
            termination of the Executive's employment, the Company and the
            Executive agree to:

      (a) Consult to the Company for two years for up to 100 hours/year and
          agrees not to violate Section 5.02 above, in exchange for the payment
          of the Executive's annual target bonus amount (paid in monthly
          installments), in accordance with the terms of the standard James
          Hardie Consulting Agreement, a copy of which is attached ("Consulting
          Agreement").

      (b) Additionally, the Company may elect to extend this Consulting
          Agreement for an additional two years, and the Executive will agree to
          such extension, in exchange for the amount equal to the annual base
          salary and target bonus for each year of extension.

                                  ARTICLE VIII
                                     RELEASE

      8.1 As a material inducement for the Company to provide compensation and
certain benefits described in the Agreement, Executive, on his own behalf and on
behalf of his spouse, heirs, executors, administrators, successors, and assigns,
hereby irrevocably and unconditionally releases, acquits and forever discharges
the Group and each of their predecessors, successors, assigns, agents,
directors, officers, employees, partners, attorneys, representatives, retirement
benefit plans, welfare benefit plans, divisions, subsidiaries, parent companies,
affiliates (and agents, directors, officers, employees, partners, attorneys,
representatives, retirement benefit plans, and welfare benefit plans of such
divisions, subsidiaries, parent companies and affiliates), and all persons
acting by, through, under or in concert with any of them (collectively,
"Releasees"), or any of them from any and all charges, complaints, claims,
liabilities, obligations, promises, agreements, controversies, damages, actions,
causes of action, suits, rights, demands, costs, losses, debts and expenses
(including attorneys' fees and costs actually incurred) (collectively, "Claims")
of any nature whatsoever known or unknown, suspected or unsuspected, including
but not limited to Claims arising under any compensation plan, welfare benefit
plan,

                                                                              10

<PAGE>

contract, agreement or understanding, whether express or implied, any tort or
other cause of action, including but not limited to those arising under federal,
state or local laws prohibiting age, sex, disability or other forms of
discrimination, including but not limited to Title VII of the Civil Rights Act
of 1964, as amended, the Employee Retirement Income Security Act of 1974, as
amended, the Age Discrimination in Employment Act of 1967, as amended, the
Americans With Disabilities Act of 1990, the Family and Medical Leave Act of
1993, the Fair Labor Standards Act of 1938, as amended, the Consolidated Omnibus
Budget Reconciliation Act of 1986, as amended, the Fair Employment and Housing
Act, any regulations thereunder, state or federal common law, or any other duty
or obligation of any kind or description whether express or implied, which
Claims relate to arise out of the Executive's change in role as set out in this
Agreement, and which Executive now has, owns or holds or claims to have, own or
hold or which Executive at any time heretofore has owned or held or claimed to
have, own or hold or claim to have, own or hold against each or any of the
Releasees, except claims arising under any applicable bonus plan, pension
benefit plan, medical benefit plan, dental benefit plan, or vision benefit plan
in which the Executive is participating as of the date of this Agreement. The
foregoing provision in this Paragraph 8.1 shall not apply to activities that are
permitted under applicable law, except that Executive acknowledges that he has
irrevocably waived any right to recovery against the Releasees in connection
with such activities, or otherwise. This Release is not intended to restrict
either Executive's or the Company's rights and obligations to abide by and/or
enforce the terms and conditions of this Agreement. For the avoidance of doubt,
the release set out in this Article VIII applies solely to Claims which relate
to arise out of the Executive's change in role as set out in this Agreement.

      8.2 As a condition of this Release, Executive waives all rights arising
under Section 1542 of the Civil Code of the State of California against
Releasees. Section 1542 provides as follows:

            A General Release does not extend to claims which a creditor does
            not know or suspect to exist in his favor as of the time of
            executing the Release which if known by him must have materially
            affected his settlement with the debtor.

Notwithstanding the provisions of Section 1542 and for the purpose of
implementing the full and complete release and discharge of the liability of all
Releasees described in Paragraph 8.1 above as of the effective date of the
Agreement, Executive expressly acknowledges that the Release is intended to
include and does include in its effect without limitation all Claims which
Executive does not know or expect to exist in his favor against Releasees as of
the time of the effective date of this Release and that this Release expressly
contemplates the extinguishment of any such Claims, including attorneys' fees
and costs.

      8.3 Executive acknowledges that he has been encouraged to consult with an
attorney before signing this Agreement, and that he may return the signed
Agreement to the Company during the period beginning with his receipt of the
Agreement and ending, without Executive's revocation, twenty-one (21) days from
the date Executive receives it. If Executive does sign this Agreement, Executive
acknowledges that he will have seven (7) days after he executes it to
voluntarily decide to revoke it, and it will not become effective until seven
(7) days has expired,

                                                                              11

<PAGE>

without Executive's revocation, from the date Executive voluntarily chose to
execute it. Executive further acknowledges that he has read this Article VIII
carefully and that he knowingly and voluntarily agrees to accept the terms and
conditions set forth in the Agreement, as consideration for the Release
described herein. Executive further acknowledges that he was provided twenty-one
(21) days within which to consider the terms of the Release, including seeking
counsel, and that the consideration described within the Agreement is sufficient
and adequate consideration for the Release as it reflects compensation and
benefits above and beyond those to which Executive is entitled as of the date of
this Release.

                                   ARTICLE IX
                                  MISCELLANEOUS

      9.01 Assignment, Successors. This Agreement, or any right or interest
herein, may not be assigned by either party hereto, whether by operation of law
or otherwise, without the prior written consent of the other party. This
Agreement shall be binding upon and inure to the benefit of the Executive and
the Executive's estate and the Company and any assignee of or successor to the
Company.

      9.02 Severability. If all or any part of this Agreement is declared by any
court or governmental authority to be unlawful or invalid, such unlawfulness or
invalidity shall not serve to invalidate any portion of this Agreement not
declared to be unlawful or invalid. Any paragraph or part of a paragraph so
declared to be unlawful or invalid shall, if possible, be construed in a manner
which will give effect to the terms of such paragraph or part of a paragraph to
the fullest extent possible while remaining lawful and valid.

      9.03 Amendment and Waiver. This Agreement shall not be altered, amended or
modified except by written instrument executed by the Company and the Executive.
A waiver of any term, covenant, agreement or condition contained in this
Agreement shall not be deemed a waiver of any other term, covenant, agreement or
condition and any waiver of any other term, covenant, agreement or condition,
and any waiver of any default in any such term, covenant, agreement or condition
shall not be deemed a waiver of any later default thereof or of any other term,
covenant, agreement or condition.

      9.04 Notices. All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed given upon personal delivery,
facsimile transmission (with confirmation of receipt), delivery by a reputable
overnight courier service or five (5) days following deposit in the U.S. mail
(if sent by registered or certified mail, return receipt requested, postage
prepaid), in each case duly addressed to the party to whom such notice or
communication is to be given as follows:

                                                                              12

                              CONSULTING AGREEMENT

      This Agreement is entered into on the later date this Agreement is signed
by the parties by and between James Hardie Building Products, Inc., a Nevada
corporation, with its principal place of business at 26300 La Alameda, Mission
Viejo, California 92691 ("Company") and the consultant named in Exhibit A
("Consultant").

      In consideration of the mutual covenants and agreements contained herein,
the adequacy and sufficiency of which is acknowledged, the parties agree as
follows:

      ARTICLE 1. SCOPE OF SERVICES. As directed by Company, Consultant shall
utilize its expertise to perform consulting and advisory services ("Services")
regarding various business operations and opportunities in which Company may
have an interest. The Services shall be rendered on an "as needed" basis and,
Consultant shall use its best efforts to make the Services available to Company
at times requested by Company. Consultant's responsibilities and milestones for
achieving the Services are stated in Exhibit A.

      ARTICLE 2. FEES, PAYMENT, DISPUTE RESOLUTION. Unless specified otherwise
in Exhibit A, the following terms regarding fees and payment shall apply.
Company shall pay Consultant for time spent performing Services at the rates set
forth in Exhibit A upon full and satisfactory performance of the Services.
Company agrees to reimburse Consultant for all reasonable out of pocket expenses
incurred by the Consultant in connection with the Services provided hereunder.
Invoices shall be submitted by Consultant to Company as soon as practical after
the end of each month and Company agrees to pay Consultant for amounts due for
such invoices within thirty (30) days of Company's receipt of such invoice.
Invoices shall provide sufficient detail and shall be in a format acceptable to
Company. If Company reasonably disputes any of the fees charged, Company shall
not pay the amount in dispute but shall notify Consultant of the amount and
reason for the dispute. The parties shall attempt in good faith to settle the
dispute by discussions between themselves. If the dispute remains unresolved
after eight weeks after Company notifies Consultant of the dispute, the parties
are free to pursue all available legal remedies.

      ARTICLE 3. EFFECTIVE DATE, TERM AND TERMINATION. Unless specified
otherwise in Exhibit A, this Agreement shall become effective on the date last
written below and shall continue to be in effect month-to-month thereafter
unless canceled as hereinafter provided and either party may terminate this
Agreement at the end of any month by giving the other party written notice of
such termination at least ten (10) days prior to the effective date of
termination; provided, however, that Company may terminate this Agreement for
cause immediately upon written notice to Consultant. Termination of the
Agreement by Company does not waive any claims for damages which it may have
against Consultant for failure to perform or insufficient performance.

      ARTICLE 4. INSURANCE. Consultant shall carry comprehensive general
liability and automobile liability insurance and, if applicable, workers'
compensation and errors and omissions insurance. The minimum limits for the
comprehensive general liability coverage shall be bodily injury $3,000,000 per
occurrence, and property coverage $3,000,000 per occurrence. The minimum limits
for the automobile liability coverage shall be bodily injury $1,000,000 per
occurrence, and property damage $1,000,000 per occurrence. All policies of
insurance shall be with a company or companies acceptable to the Company and
Consultant shall provide to Company upon execution of this Agreement and upon
Company's request, a certificate of insurance demonstrating that proper
coverages are in place.

      ARTICLE 5. CONSULTANT'S AUTHORITY. Consultant is an independent
contractor, not an agent or employee of Company. Consultant has no authority to
enter into any contract or incur any other obligation on behalf or in the name
of Company. Consultant shall be solely responsible for all of its own employees
and expenses.

      ARTICLE 6. INDEMNIFICATION. Consultant shall indemnify and hold harmless
Company, its affiliates, agents and employees from and against all actions,
claims, demands, liabilities, damages, losses, costs and expenses (including,
but not limited to, attorney's fees and those arising in any bankruptcy or
insolvency proceeding) which relate to personal or bodily injury, sickness,
disease, death or injury or damage to property of any kind (including, without
limitation, the loss of use thereof) and any breach by Consultant of the terms
of this Agreement ("Claims") where such Claims arise out of, or by reason of, an
act or omission of Consultant, its employees or agents.

      ARTICLE 7. WARRANTY. Consultant warrants that: (a) the Services shall be
performed in a good and workmanlike manner in accordance with established
professional standards for such services and the best practices in Consultant's
industry, (b) the Services and any reports, advice and other products of
Consultant's Services shall comply

                                       1

<PAGE>

with all applicable laws, regulations, codes and ordinances, and (c) to the
extent that the Services involve delivery of "Technology" to Company, use of
such Technology by Company does not infringe or violate any patent, copyright,
trade secret or other proprietary right of any person or entity and, to the
extent that the Services involve development of Technology, such Technology is a
"work made for hire" (or if for any reason the Technology is deemed to not be a
"work made for hire," Consultant hereby assigns all its rights in such
Technology to Company) and Company shall have full and clear title to any and
all Technology resulting from the Services (except as provided in Exhibit A) and
shall be able to use any and all such Technology without liability and without
restriction. "Technology" includes such things as, without limitation, software
programs developed by Consultant as part of the Services. If Consultant fails to
comply with this warranty, Company may, in addition to exercising any of its
other rights and remedies under this Agreement or otherwise at law, require that
Consultant perform the Services again, properly and at no additional expense to
Company.

      ARTICLE 8. OWNERSHIP OF PRODUCTS OF SERVICES. All reports, data, ideas,
information and other products of the Services delivered by Consultant to
Company hereunder or developed by Consultant in performing the Services shall be
the sole and exclusive property of Company and shall be deemed "work made for
hire" with Company receiving ownership of copyright therein. Consultant hereby
assigns all such rights to Company.

      ARTICLE 9. MAINTENANCE OF RECORDS. Consultant shall maintain accurate
records, sufficient and acceptable to Company, pertaining to the Services and
agrees to retain all such records for at least three years after completion of
Services. Any representative(s) authorized by Company may audit transactions
related hereto for the purpose of determining whether there has been compliance
with this Agreement.

      ARTICLE 10. CONFIDENTIALITY.

      10.1 The term "Confidential Information" means all information which
Consultant receives before, during and after the engagement hereunder which: (a)
is provided to Consultant by Company or an affiliate company that concerns or
relates to any aspect of the business of Company or an affiliate company; or (b)
is, for any reason, identified and treated as confidential by the Company and/or
its affiliate companies. Confidential Information does not include such
information which Consultant can prove, by clear and convincing evidence: (c) at
the time of this Agreement is publicly and openly known and in the public
domain; (d) after the date of this Agreement becomes publicly and openly known
and in the public domain through no fault of Consultant; or (e) is in
Consultant's possession and documented prior to this Agreement, lawfully
obtained by Consultant other than from the Company and not subject to any
obligation of confidentiality.

      10.2 Consultant understands and acknowledges that the Confidential
Information is being revealed to Consultant in strict confidence solely for the
purpose of allowing Consultant to perform the Services. Consultant shall not
use, or induce others to use, any Confidential Information for any other purpose
whatsoever nor at any time directly or indirectly print, copy or otherwise
reproduce, in whole or in part, any Confidential Information without the prior
written consent of Company.

      10.3 Consultant shall not disclose or reveal any Confidential Information
to anyone except those of Consultant's employees with a definable need to know
such Confidential Information. Prior to revealing or disclosing Confidential
Information to such employees, Consultant shall require the employees to agree
to and be bound by the terms of this Agreement.

      10.4 Upon completion of the Services, or upon request of Company,
Consultant shall deliver to Company all Confidential Information embodied in
tangible form. Consultant shall deliver to Company all originals and copies of
documents, data, software, programs and things, including all recordings on
electronic, magnetic optical or other media, and all listings, comprising or
embodying Confidential Information and shall not take or retain any copies
thereof. The confidentiality provision herein shall survive termination of this
Agreement and Confidential Information shall be held as confidential until it is
no longer Confidential Information as provided herein.

      10.5 Consultant acknowledges that any unauthorized disclosure or use of
Confidential Information to which it is given access by virtue of this Agreement
would cause Company immediate and irreparable injury or loss. Accordingly,
Consultant acknowledges and agrees that in the event of a breach or threatened
breach by Consultant of any provision of this Agreement, Company shall be
entitled to preliminary and permanent injunctive relief, without the need to
post a bond, restraining Consultant from the disclosure or unauthorized use of
any Confidential Information.

                                       2

<PAGE>

      10.6 The terms of this confidentiality provision supplement the terms of
any separate confidentiality agreement signed by the parties, regardless of any
integration clause, and if there is any conflict in such terms, the provision
providing the most protection to the Confidential Information shall be applied.

      ARTICLE 11. NON-COMPETITION.

            (a) The Consultant agrees that the Consultant shall not during the
Consulting Agreement with the Company, directly or indirectly, in any capacity,
engage or participate in, or become employed by or render advisory or consulting
or other services in connection with any Prohibited Business as defined in
Article 11(c).

            (b) The Consultant agrees that the Consultant shall not during the
Consulting Agreement with the Company, make any financial investment, whether in
the form of equity or debt, or own any interest, directly or indirectly, in any
Prohibited Business. Nothing in this Article 11(b) shall, however, restrict the
Consultant from making any investment in any company whose stock is listed on a
national securities exchange; provided that (i) such investment does not give
the Consultant the right or ability to control or influence the policy decisions
of any Prohibited Business, and (ii) such investment does not create a conflict
of interest between the Consultant's duties hereunder and the Consultant's
interest in such investment.

            (c) For purposes of this Article 11, "Prohibited Business" shall be
defined as the business of:

                  (i)   marketing or selling of fiber cement products, where the
                        marketing or selling of such products is a principal
                        activity of the business;

                  (ii)  manufacturing or processing fiber cement products;

                  (iii) building, assembling, operating or maintaining plant and
                        equipment, where that plant and equipment is particular
                        to the manufacturing or processing of fiber cement
                        products;

                  (iv)  manufacturing or processing raw materials for fiber
                        cement products where that manufacturing or processing
                        is particular to the raw material used in fiber cement
                        products;

                  (v)   research or development activities relating to Article
                        11(c)(i)-(iv); and

and any branch, office or operation thereof, which is a competitor of the
Company or which has established or seeks to establish contact, in whatever form
(including, but not limited to solicitation of sales, or the receipt or
submission of bids), with any entity who is at any time a client, customer or
supplier of the Company (including but not limited to all subdivisions of the
federal government.)

      ARTICLE 12. NO ASSIGNMENT. Consultant shall not assign part or all of this
Agreement without Company's prior written consent. Any independent contractors
or consultants which Consultant engages to perform Services hereunder, and the
specific portion of the Services they will perform, must be approved by the
prior written consent of Company.

      ARTICLE 13. SAFETY COMPLIANCE. Consultant agrees to comply with all
Company health and safety guidelines and requirements while on Company property.

      ARTICLE 14. GOVERNMENT CONTRACTS. If compensation to Consultant under this
Agreement exceeds $10,000 and is in furtherance of a U.S. Government contract or
subcontract, the provisions of the Equal Opportunity Clause as promulgated by
Section 202 of Executive Order 11246, dated September 24, 1965, as amended, are
incorporated herein by reference. Consultant also agrees to comply with all
applicable local, state and federal laws and executive orders and regulations
issued pursuant thereto, including any such rules which may be applicable to
this Agreement as a U.S. Government subcontract.

                                       3

      ARTICLE 15. INDEPENDENT CONTRACTOR STATUS. Consultant and Company
acknowledge that Consultant is engaged under this Agreement as an independent
contractor, and not an employee, of Company. Consultant and Company further
acknowledge that Consultant retains control over the method and manner in which
the Services are to be performed under the Agreement. Consultant and Company
further acknowledge that as an independent contractor, all taxes due to federal,
state and local authorities are the sole responsibility of the Consultant. The
Consultant agrees that it will indemnify and hold Company harmless for any tax
liabilities that may arise as a consequence of this Agreement, and understands
as a consideration of this Agreement that it must remain in compliance with all
laws and regulations applicable to business entities or otherwise.

      ARTICLE 16. MISCELLANEOUS. This Agreement, including Exhibit A and any
attachments thereto, constitutes the entire agreement between the parties and
supersedes all prior oral or written representations, understandings, covenants
and agreements relating to the subject hereof, except the Employment Agreement
made and entered the 1st day of Sept, 2004 by and between James Hardie Building
Products, Inc. and David Merkley, and, except as otherwise set forth herein, may
be amended only by a writing signed by both parties. This Agreement shall be
governed by and construed in accordance with the laws of the State of California
without regard to its conflict of laws principles. Consultant agrees and hereby
submits to the jurisdiction of the courts for the State of California in the
County of Orange. Any provision herein held to be invalid, unenforceable, void
or illegal, in whole or in part, by any tribunal of competent jurisdiction,
shall be severed from this Agreement and replaced by a provision that is valid
and enforceable and that comes closest to expressing the intention of such
invalid or unenforceable provision. All remedies provided herein are cumulative
and in addition to any other available remedy. This Agreement may be executed in
counterparts each of which shall be deemed an original and all of which together
shall constitute one and the same document. This Agreement may not be modified
except by a subsequent writing executed by the parties. This Agreement will be
interpreted as if written jointly by the parties. This Agreement will benefit
the affiliates, successors and assigns of Company, and will be binding upon the
affiliates, successors and assigns of Consultant.
