     1.3. BUSINESS AND AUTHORITY. The Company is formed for the specific and
limited purpose of operating the laundry detergent joint venture between CHD and
USAD, which includes, among other matters, the manufacture, distribution and
sale of liquid and powder laundry detergent and liquid fabric softener products
(the "BUSINESS"). The Company shall have the authority to do all things
necessary or convenient to accomplish its purpose and operate the Business as
described in this Section 1.3. The Company exists only for the purpose specified
in this Section 1.3, and may not conduct any other business without the Consent
(as defined in Section 2.4 hereof) of the Members. In particular, except as
specifically contemplated by this Agreement, the Business shall not extend to
any activity that will compete with any of the Other CHD Products or any of the
Other USAD Products (each as defined in Section 6.2 below). The authority
granted to the Board hereunder to bind the Company shall be limited to actions
necessary or convenient to the Business.

     1.4 EFFECTIVE DATE AND TERM. The "EFFECTIVE DATE" shall be the date, not
later than January 1, 2001, specified by CHD in a notice delivered to USAD at
any time after the date hereof (the date of such notice is referred to herein as
the "TRIGGER DATE"); provided, however, that the Effective Date shall not occur
prior to, and shall be contingent upon, the expiration of the waiting period, if
any, required under the Hart-Scott-Rodino Antitrust Improvements Act (the "HSR
ACT"); provided further, that USAD's obligations hereunder, including without
limitation the payment of any Capital Contributions (as hereinafter defined) and
Change of Control (as hereinafter defined) fees, shall be subject to the prior
written consent of FINOVA Capital Corporation, as agent and lender (the
"Agent"), and the other lenders (each a "Lender" and, collectively, the
"Lenders") parties to that certain Amended and Restated Loan and Security
Agreement, dated February 25, 1999, between such Lenders and USAD and its
subsidiaries (the "USAD Loan Agreement"), under the USAD Loan Agreement. If
within forty five (45) days after the date hereof (the "FINOVA CONSENT PERIOD")
USAD has not obtained the consent of the Agent and the Lenders to the
transactions contemplated hereby (including without limitation Section 9.4(e)
hereof) or replaced the loan facilities contemplated by the USAD Loan Agreement
(including the revolving credit facility, all term notes and loans and all other
credit facilities thereunder) with facilities reasonably acceptable to CHD,
then, notwithstanding the fact that CHD has given notice of the Effective Date
as contemplated by this Section 1.4, CHD shall have the right, exercisable by
written notice to USAD no later than forty five (45) days after the expiration
of the Finova Consent Period, to either (i) provide replacement loan facilities
reasonably acceptable to USAD or (ii) terminate this Agreement effective upon
delivery by CHD of such written notice to USAD. The term of the Company shall
then continue until the Company's dissolution in accordance with the provisions
of Article X of this Agreement. If the Effective Date has not occurred by
January 1, 2001, this Agreement shall be null and void.

     1.5 AGREEMENT; EFFECT OF INCONSISTENCIES WITH THE ACT. It is the express
intention of the Members that this Agreement and the contracts and documents
referred to herein shall be the sole source of agreement of the parties with
respect to the matters dealt with herein and, except to the extent a provision
of this Agreement expressly incorporates federal income tax rules by reference
to sections of the Code or Regulations or is expressly prohibited or ineffective
under the Act, this Agreement shall govern, even when inconsistent with, or
different than, the provisions of the Act or any other law or rule. To the
extent that any provision of this Agreement is prohibited or ineffective under
the Act, this Agreement shall be deemed to be amended to the smallest degree
possible in order to make this Agreement effective under the Act


                                       2
<PAGE>

in accordance with the intent of the parties. In the event the Act is
subsequently amended or interpreted in such a way to make any provision of this
Agreement that was formerly invalid valid, such provision shall be considered to
be valid from the effective date of such interpretation or amendment. The
Members hereby agree that each Member shall be entitled to rely on the
provisions of this Agreement, and no Member shall be liable to the Company or to
any Member for any action or refusal to act taken in good faith reliance on the
terms of this Agreement and which is in substantial compliance with the terms
hereof. The Members hereby agree that the duties and obligations imposed on the
Members as such shall be those set forth in this Agreement, which is intended to
govern the relationship among and between the Company and the Members,
notwithstanding any provision of the Act or common law to the contrary.

                                  ARTICLE III.

                         CAPITAL CONTRIBUTIONS AND LOANS
                         -------------------------------

         3.1 INITIAL CAPITAL CONTRIBUTIONS. Promptly upon the Effective Date,
each Member shall deliver to the Company payment of such Member's initial
Capital Contribution, which contributions shall include:

         (a) An exclusive license, in form and substance to be negotiated in
good faith between the parties (the "CHD LICENSE"), of CHD's technology and
intellectual property with respect to liquid and powder laundry detergent
products, including without limitation liquid fabric softeners, manufactured and
sold by CHD as listed on Schedule 3.1(a) hereto, but excluding CHD's "Delicare"
line of products, Arm & Hammer washing soda and fabric softener sheets (the "CHD
DETERGENT PRODUCTS");

         (b) An exclusive license, in form and substance to be negotiated in
good faith between the parties (the "USAD LICENSE"), of USAD's technology and
intellectual property with respect to liquid and powder laundry detergent
products, including without limitation liquid fabric softeners, manufactured and
sold by USAD as listed on Schedule 3.1(b) hereto (the "USAD DETERGENT
PRODUCTS");

         (c) All finished goods inventories of CHD Detergent Products and USAD
Detergent Products which are reasonably saleable within the next sixty (60)
days; and

         (d) Cash in amounts determined unanimously by the Board thirty (30)
days before the Effective Date as necessary to fund working capital needs of the
Company during the ninety (90) days following the Effective Date. Each Member's
initial cash Capital Contribution shall be determined so as to ensure that the
total aggregate amount of the Members' initial Capital Contributions be split
60% CHD and 40% USAD. If, due to an imbalance in finished goods inventories
contributed to the Company, USAD is unable to make its full initial cash Capital
Contribution required by this Section 3.1(d), then the shortfall shall be
provided by CHD and such shortfall shall be treated as a loan by CHD to the
Company (bearing interest at a market rate) which shall be repaid to CHD as soon
as the Company has sufficient cash flow to do so.

The contributions made pursuant to paragraphs (a) and (b), above, will be
assigned a value of zero for the purpose of each Member's Capital Contribution
and Capital Account (as defined in Section 4.1).

     3.2 INTEREST ON CAPITAL CONTRIBUTIONS. No Member shall be entitled to
receive any interest on such Member's Capital Contribution.

     3.3 ADDITIONAL CAPITAL CONTRIBUTIONS. No Member shall be required or
obligated to restore a deficit Capital Account balance upon the liquidation of
the Company or such Member's Ownership Interest in the Company. No Member shall
be allowed or required to make any additional contribution to the capital of the
Company in excess of $3,000,000 in the aggregate during any six month period,
without the unanimous authorization of the Board. Additional capital
contributions from each Member of $3,000,000 or less in the aggregate during any
six month period may be required by a majority of the Board. All additional
capital contributions



                                       5
<PAGE>

shall be made by the Members in the same proportion as their average percentage
allocations of Net Profit and Net Loss pursuant to Section 4.4 hereof for the
immediately preceding fiscal year of the Company.

     3.4 WITHDRAWAL OF CAPITAL. Except in connection with proceedings to
dissolve the Company in accordance with the procedures set forth in Article X of
this Agreement, no Member may withdraw any portion of such Member's Capital
Contribution, or any portion of such Member's Capital Account, from the Company
without the prior unanimous authorization of the Board.

     3.5 LOANS BY MEMBERS. Other than as provided in Section 3.1(d) hereof, a
Member may make a loan or advance money or property to or on behalf of the
Company, only upon such terms as the Board has unanimously authorized. Any
permitted loan or advance shall not increase the lending Member's Capital
Account, entitle the lending Member to any greater share of Company
distributions made in respect of a Member's Capital Account or subject such
lending Member to any greater proportion of Company losses. The amount of such
loans or advances shall be a debt owed by the Company to the lending Member, and
any interest paid to the lending Member shall be charged as any other expense
against income of the Company.

                                   ARTICLE IV.

                CAPITAL ACCOUNTS, DISTRIBUTIONS, AND TAX MATTERS
                ------------------------------------------------

     4.1 ESTABLISHMENT OF CAPITAL ACCOUNTS. A separate capital account ("CAPITAL
ACCOUNT") shall be established and maintained for each Member in accordance with
the principles set forth in Sections 704(b) and 704(c) of the Code and the
Regulations. The Capital Account of each Member shall initially be equal to the
sum of: (i) the full amount of cash contributed by such Member to the Company
and (ii) except as specifically provided by Section 3.1, the fair market value,
as determined by the Board in good faith, of other property contributed by such
Member to the Company (net of liabilities secured by such property that the
Company is considered to assume or take subject to under Section 752 of the
Code). The provisions of this Agreement relating to the maintenance of Capital
Accounts are intended to comply with Regulation Section 1.704-1(b) relating to
the maintenance of capital accounts, and shall be interpreted and applied in a
manner consistent with such Regulation. In the event the Board deems it
advisable to modify the manner in which the Capital Accounts, or any debits or
credits thereto, are computed in order to comply with such Regulation, the Board
may make such modification, provided that it is not likely to have a material
effect on the amounts which would otherwise be distributable to any Member upon
the dissolution of the Company.

     4.2 INCREASES AND DECREASES IN CAPITAL ACCOUNTS. Each Member's Capital
Account shall be increased by any additional Capital Contributions made by such
Member to the Company (in the case of contributed property, such increase shall
equal the fair market value, as determined by the Board in good faith, of such
property net of liabilities secured by such property that the Company is
considered to assume or take subject to under Section 752 of the Code) and a
Member's allocated share of Net Profit (as defined in Section 4.3 hereof), and
decreased by any money and the fair market value, as determined by the Board in
good faith, of any property distributed to such Member by the Company (net of
liabilities secured by the



                                       6
<PAGE>

distributed property that the Member is considered to assume or take subject to
under Section 752 of the Code) and such Member's allocated share of Net Loss (as
defined in Section 4.3 hereof).

     4.3 NET PROFIT AND NET LOSS. For the purposes of this Agreement, the term
"NET PROFIT" or "NET LOSS" shall mean an amount equal to the Company's net
income or loss for the relevant fiscal year or shorter period, determined in
accordance with generally accepted accounting principles and procedures
consistently applied.

     4.4 ALLOCATIONS OF NET PROFIT AND NET LOSS. The Net Profit or Net Loss of
the Company for each fiscal year or shorter period following the Effective Date
shall be allocated as follows:

         (a) Except as otherwise expressly provided in this Section 4.4, Net
Profit up to $30,000,000 (or a proportionately reduced amount of Net Profit for
a period shorter than a full fiscal year) shall be allocated 65% to CHD and 35%
to USAD and any Net Profit in excess of $30,000,000 (or a proportionately
reduced amount of Net Profit for a period shorter than a full fiscal year) shall
be allocated 55% to CHD and 45% to USAD;

         (b) Notwithstanding Section 4.4(a) hereof, in the event CHD's operating
profit for its 2000 fiscal year from the sale of CHD Detergent Products (as
computed in accordance with Exhibit A hereto) is less than [*] (the amount of
such deficiency being hereinafter referred to as the "CHD Deficiency"), then
CHD's allocable share of Net Profit up to $30,000,000 (or a proportionately
reduced amount of Net Profit for a period shorter than a full fiscal year,
taking into account spending patterns and other appropriate adjustments as
determined in good faith by the unanimous approval of the Board) shall be
reduced, but not below 60%, in the same ratio as the CHD Deficiency bears to
[*], and USAD's allocable share of such Net Profit shall be correspondingly
increased. For example, if the CHD Deficiency is $[*], the adjustment would
be [*] x [*]% = [*]%. CHD's allocable share would be reduced by [*]% to [*]% and
USAD's allocable share would be increased by [*]% to [*]%. In no event would
CHD's allocable share be reduced below 60%;

         (c) Notwithstanding Section 4.4(a) hereof, in the event USAD's
operating profit for its 2000 fiscal year from the sale of USAD Detergent
Products (as computed in accordance with Exhibit B hereto) is less than [*] (the
amount of such deficiency being hereinafter referred to as the "USAD
Deficiency"), then USAD's allocable share of Net Profit up to $30,000,000 (or a
proportionately reduced amount of Net Profit for a period shorter than a full
fiscal year, taking into account spending patterns and other appropriate
adjustments as determined in good faith by the unanimous approval of the Board)
shall be reduced, but not below 30%, in the same ratio as the USAD Deficiency
bears to [*], and CHD's allocable share of such Net Profit shall be
correspondingly increased. For example, if the USAD Deficiency is $[*], the
adjustment would be $[*] x [*]% = [*]%. USAD's allocable share would be reduced
by [*]% to [*]% and CHD's allocable share would be increased by [*]% to [*]%.
In no event would USAD's allocable share be reduced below 30%;

                                       7
<PAGE>

         (d) Net Loss shall be allocated first to each Member based on, and to
the extent of, previous allocations of Net Profit to such Member and then based
on the then current percentages of Net Profit to be allocated to such Member
pursuant to this Section 4.4. Notwithstanding the foregoing, except as otherwise
provided in this Section 4.4(d), no Member shall be allocated Net Loss in any
fiscal year or shorter period to the extent such allocation would create or
increase a deficit in the Capital Account of such Member (the "Loss
Limitation"). Any Net Loss otherwise allocable to a Member but for the Loss
Limitation ("Contingent Loss") shall be allocated among the other Members, pro
rata based on their respective positive Capital Account balances, subject to the
Loss Limitation. Remaining Net Loss, if any, in excess of the Net Loss allocated
under the immediately preceding sentence shall be allocated among the Members
pro rata based on their respective Capital Account balances. To the extent that
Members are allocated Contingent Loss, subsequent Net Profit first shall be
allocated to the Members in reverse order of, and in an amount equal to, the
Contingent Loss previously allocated to them pursuant to this Section 4.4(d)
prior to any allocation of Net Profit in accordance with this Section 4.4; and

         (e) In the event of a Transfer (as defined in Section 9.1 hereof) of
all or any portion of an Ownership Interest in accordance with the provisions of
this Agreement at any time other than the end of a fiscal year, the shares of
items of Net Profit or Net Loss and special allocations of items of income or
loss allocable to such Ownership Interest (or the Transferred portion thereof)
shall be allocated between the transferor and the transferee in a manner that is
consistent with the applicable provisions of the Code.

     4.5 TAX ALLOCATIONS.

         (a) Each item of income, gain, loss, deduction or credit for federal,
state and local income tax purposes shall be allocated among the Members in the
same proportion as the allocation of Net Profit, Net Loss and other items to the
Members pursuant to Section 4.4 hereof, except as otherwise provided herein. The
allocations made pursuant to this Section 4.5 shall be solely for tax purposes
and shall not affect any Member's Capital Account or share of non-tax
allocations or distributions under this Agreement.

         (b) In the event the book value of any property contributed to the
Company by a Member differs from its tax basis, allocations of taxable income,
gain, loss and deduction with respect to such property shall be made in a manner
which complies with Section 704(c) of the Code and the Regulations. The Company
may, in the sole discretion of the Board, make, or not make, "curative" or
"remedial" allocations (within the meaning of the Regulations under Section
704(c) of the Code) of Net Profit or Net Loss with respect to such property.

     4.6 SPECIAL ALLOCATIONS. The following special allocations shall be made in
the following order:

         (a) Minimum Gain Chargeback. In the event that there is a net decrease
during a fiscal year or shorter period in either Company Minimum Gain (within
the meaning of the definition of partner minimum gain in Regulation Section
1.704-2(b)(2)) or Member Nonrecourse Debt Minimum Gain (within the meaning of
the definition of partner nonrecourse debt minimum gain in Regulation Section
1.704-2(i)(3)), then, notwithstanding any other



                                       8
<PAGE>

provision of this Article IV, each Member shall receive such special allocation
of items of Company income and gain as are required in order to conform to
Regulation Section 1.704-2.

         (b) Qualified Income Offset. Subject to Section 4.6(a), but
notwithstanding any other provision of this Article IV, items of income and gain
shall be specially allocated to the Members and in a manner that complies with
the "qualified income offset" requirement of Regulation Section
1.704-1(b)(2)(ii)(d)(3).

         (c) Gross Income Allocation. In the event that a Member has a deficit
Capital Account at the end of any fiscal year or shorter period which is in
excess of the amount such Member is deemed to be obligated to restore pursuant
to the penultimate sentences of Regulation Sections 1.704-2(g)(1) and
1.704-2(i)(5), respectively, such Member shall be specially allocated items of
Company income and gain in the amount of such excess as quickly as possible,
provided that any allocation under this Section 4.6(c) shall be made only if and
to the extent that a Member would have a deficit Capital Account in excess of
such sum after all allocations provided for in this Article IV have been
tentatively made as if this Section 4.6(c) were not in this Agreement.

         (d) Nonrecourse Deductions. Any item of Company loss or deduction (or
expenditure subject to Section 705(a)(2)(B) of the Code) that is attributable to
Member Nonrecourse Debt (within the meaning of the definition of partner
nonrecourse debt in Regulation Section 1.704-2(b)(4)) shall be specially
allocated to the Members in the manner in which they share the "economic risk of
loss" (as defined in Regulation Section 1.752-2) for such Member Nonrecourse
Debt. Any nonrecourse deductions, within the meaning of Regulation Section
1.704-2(b)(1), shall be specially allocated among the Members in proportion to
their respective Capital Accounts.

         (e) Regulatory Allocations. In the event an allocation is or has been
prevented or required pursuant to Sections 4.6(a)-(d), above, the Board
subsequently may make special allocations of Net Profit or Net Loss (or
individual items thereof) to the extent that, in its judgment, such allocations
would (i) be respected under applicable federal income tax law and (ii)
eliminate as quickly as possible the difference between the actual Capital
Account of each Member and the Capital Account such Member would have had in the
absence of such Sections 4.6(a)-(d).

     4.7 CONFORMANCE WITH THE CODE AND APPLICABLE REGULATIONS. It is intended
that Sections 4.1, 4.2, 4.3, 4.4, 4.5 and 4.6 of this Agreement be construed and
applied in a manner consistent with the requirements of Code Sections 704(b) and
704(c) and the Regulations. If, in the opinion of the Company's accountant, the
manner in which Sections 4.1, 4.2, 4.3, 4.4, 4.5 and 4.6 of this Agreement apply
should be modified in order to comply with Code Sections 704(b) and 704(c) and
the Regulations, then, notwithstanding anything to the contrary contained in
Sections 4.1, 4.2, 4.3, 4.4, 4.5 and 4.6, the method by which Capital Accounts
are maintained shall be so modified; provided, however, that any change in the
manner of maintaining Capital Accounts shall not materially alter the economic
agreement between and among the Members.

     4.8 DISTRIBUTIONS.

                                       9
<PAGE>


         (a) Net cash flow, if any, shall be distributed to the Members
following receipt by the Company of such cash. For this purpose, the term "NET
CASH FLOW" means the gross cash proceeds of the Company less the portion thereof
used to pay or establish reserves for all Company expenses, debt payments, and
contingencies as determined by the Board; provided that any reserves aggregating
an amount in excess of $3,000,000 at any time shall require unanimous Board
approval. All distributions of cash or other assets available for distribution,
from whatever source derived, shall be paid or distributed to the Members in
proportion to their respective positive Capital Account balances. Any
distributions of property other than cash shall be made at such times and in
such amounts as determined by the Board. Immediately prior to any distribution
under this Section 4.8, the Capital Accounts of the Members shall be adjusted as
provided in Regulation Section 1.704-1(b)(2)(iv)(f). Except as otherwise
provided under the Act or in this Agreement, no Member shall be required to
restore to the Company any amounts properly distributed to it pursuant to this
Section 4.8(a).

         (b) The Company shall withhold taxes from distributions to the Members
to the extent required by the Code or any other applicable law. For purposes of
this Agreement, any taxes withheld by the Company from a distribution to any
Member shall be deemed to be a cash distribution or payment to such Member, and
the amount otherwise distributable to such Member pursuant to this Agreement
shall be reduced by the taxes so withheld. The withholdings referred to in this
Section 4.8(b) shall be made at the maximum applicable statutory rate under the
applicable tax law unless the Company shall have received an opinion of counsel
or other evidence satisfactory to the Board that a lower rate is applicable or
that no withholding is applicable.

     4.9 FISCAL YEAR; TAX DECISIONS. The tax and fiscal accounting year of the
Company shall end on the 31st day of December each year. The Board shall appoint

judgment, except as otherwise required by applicable law.

         (b) The Company shall indemnify and hold harmless each director against
any loss, claim, damage, or expense, including reasonable attorneys' fees and
costs arising out of any claim, demand, suit, or action related to the

activities of the Company, unless such director is guilty of gross negligence,
gross misconduct, or willful malfeasance in connection therewith.

     6.1 MANUFACTURING. Promptly upon the Effective Date, each Member shall
provide the Company with all necessary arrangements as determined and required
by the Board to ensure the manufacture and production of the CHD Detergent
Products and the USAD Detergent Products as specified below, which arrangements
shall include, among other matters:

         (a) CHD will manufacture heavy powder laundry detergent products;

         (b) USAD will manufacture liquid and light powder laundry detergent and

         (c) Each of CHD and USAD will manufacture, package and label products
to specifications established by the Board;

         (d) Each of CHD and USAD will at all times have and maintain in full
force and effect all permits required in connection with its manufacturing
obligations hereunder;

         (e) Each of CHD and USAD will, at its own expense, make any and all
capital improvements to its facilities necessary to perform its manufacturing
obligations as reasonably required by the Board, including without limitation
those improvements needed to increase capacity or enhance efficiency; provided,
however, that any such improvements that require the expenditure by either CHD
or USAD of more than $5 million, in the aggregate, in a calendar year shall
require the unanimous approval of the Board; and

         (f) The Company will be charged for such services by CHD and USAD on
the following basis:

             (i) all direct costs at the cost thereof, with any dispute to be
resolved by the Company's auditors;

             (ii) all fully dedicated costs at the cost thereof, with any
dispute to be resolved by the Board;

             (iii) all shared costs by appropriate allocation of such costs
based on activity-based costing or another mutually agreed upon basis, with any
dispute to be mutually agreed between CHD and USAD;

             (iv) depreciation of capital improvements made pursuant to Section

<PAGE>

             (v) the Company shall not be charged for any environmental matters
(including, without limitation, costs of remediation and fines) associated with
the manufacture and production of the CHD Detergent Products and the USAD
Detergent Products.

     6.2 DISTRIBUTION.

         (a) Each of CHD and USAD will distribute the CHD Detergent Products and
the USAD Detergent Products through their respective warehouses. The Company
shall reimburse each of CHD and USAD for the actual full cost of storage,
handling and freight (including appropriate warehousing overhead) with respect
to the CHD Detergent Products and the USAD Detergent Products; provided,
however, that the Company shall not be liable for any profit margin or other
overhead allocation.

         (b) The Company shall, upon the written request of CHD, designate a
Member to operate full service warehouses at any location which CHD deems
necessary in order to optimize distribution of all CHD products other than the
CHD Detergent Products (the "OTHER CHD PRODUCTS") or for customer service
purposes.

         (c) Each of CHD and USAD will, at its own expense, install warehouse
and other management systems as required by the Board in order to improve
warehouse efficiency; provided, however, that any such installation or system
that requires the expenditure by either CHD or USAD of more than $1 million in a
calendar year shall require the unanimous approval of the Board. Amortization of
expenditures for new warehouse systems required by the Board will be as agreed
between the Company and CHD or USAD, as the case may be, with any dispute to be
resolved by the Company's auditors. The Company shall also, upon the written
request of CHD, designate a Member to operate VMI or other similar customer
service programs and install warehouse and other management systems which CHD
believes necessary for efficient warehouse operation.

         (d) In addition to the CHD Detergent Products and the USAD Detergent
Products, the Company shall, upon the written request of either CHD or USAD,
designate a Member to distribute all USAD products other than the USAD Detergent
Products (the "OTHER USAD PRODUCTS") and Other CHD Products. In any such case,
the Company or designated Member shall provide CHD or USAD, as the case may be,
[*] and the requesting Member shall reimburse the Company or designated Member
for the actual full cost for storage, handling and freight (including
appropriate warehousing overhead), [*] provided that the total amount shall not
exceed [*].

         (e) CHD and USAD shall, to the extent reasonably necessary, integrate
their MIS logistics functions as optimally as possible for the Company's
operations, recognizing that each of CHD and USAD desires to retain separate
logistical capabilities.

         (f) USAD will be the distributor for USAD laundry detergent products in
USAD's Metro business as in existence from time to time and internationally.
USAD and CHD



                                       14

will agree on transfer pricing with respect to such USAD Detergent
Products in order to achieve a fair division of profits.

     6.3 SELLING, GENERAL & ADMINISTRATIVE FUNCTIONS.

         (a) Except by Consent, the selling, general and administrative ("SG&A")
functions of the Company shall be allocated between the Members as follows:

             (i) order processing, billing and collection, logistics at its
plants and warehouses, heavy powder manufacturing management, general accounting
and cash management, marketing and research and development shall be the
responsibility of CHD;

             (ii) logistics at its plants and warehouses and liquid and light
powder manufacturing management shall be the responsibility of USAD; and

             (iii) quality assurance and development support shall be the joint
responsibility of CHD and USAD.

         (b) The Company shall reimburse each of CHD and USAD for their
respective direct costs associated with providing the SG&A functions set forth
herein. In the event that the SG&A services are dedicated solely to the
Business, the Company shall reimburse the Member for the full cost of these
services. In the event that the SG&A services are shared between the Business
and either Other CHD Products or Other USAD Products, the Company shall
reimburse the Member for the fair allocation based on activity-based costing or
another mutually agreed upon basis. The Company shall in no event be liable for
indirect costs, such as general management, corporate accounting, human
resources and legal services, unless otherwise agreed to by the Company through
a unanimous Board action.

         (c) Each of CHD and USAD will cause certain members of its sales force
to be dedicated to the sale of the Company's products and to be compensated, at
least in part, based on the success of those efforts. Subject to the reasonable
approval of USAD, the Company shall, upon the written request of CHD, require
its dedicated sales organization to coordinate its activities with CHD's
personal care sales force and, in particular, to use the same broker
organizations that CHD uses for the Other CHD Products.

         (d) The Company shall, upon the written request of CHD, sell all the
Other CHD Products and shall, upon the written request of USAD, sell its candle
line to all customers and its cleaners line to all non-food customers (i.e.,
drug and mass merchandising outlets); provided that in all cases such products
meet the specified minimum volume levels established by unanimous vote of the
Board. CHD and USAD shall reimburse the Company for these services at the fully
allocated cost, which may be a percentage of sales or another mutually agreed
upon basis.

     6.4 REVIEW RIGHT. Each Member shall have the right, on not less than ten
(10) business days notice, to review the books and records of the Company and
the other Member relating to product sales and all expenses for which the
non-auditing Member is entitled to reimbursement and for other financial matters
relating to the business of the Company. Any dispute relating to the results of
such review shall be resolved by the Company's auditors.

writing by such Member or director. Except as required by law, no Member or
director shall be liable to the Company, the other Members, creditors of the
Company or any other person for the repayment of amounts received from the
Company consistent with the provisions hereof. The failure of the Company to
observe any formalities or requirements relating to the exercise of its powers
or management of its business or affairs under this Agreement or the Act shall
not be grounds for imposing personal liability on the Members or any director
for liabilities of the Company.

agree to the holding of a meeting at such time and place, such meeting shall be
valid without call or notice, and at such meeting lawful action may be taken.

     7.10 RECORD DATE. For the purpose of determining Members entitled to notice
of or to vote at any meeting of Members or any adjournment thereof, or Members
entitled to receive payment of any distribution, or in order to make a
determination of Members for any other purpose, the date on which notice of the
meeting is mailed or the date on which the resolution declaring such

which might have been transacted at the meeting as originally noticed.

Members, the Members must act by Consent.

     8.1 COMPETITIVE ACTIVITIES. Neither this Agreement, nor the existence of
the Company, nor any activity undertaken pursuant hereto and in compliance
herewith shall prevent or restrict the investment or other business activities
of any Member apart from the Company, nor shall the Company or any other Member
or director have any right, by virtue of this Agreement or the existence or
operation of the Company, to participate in, or to receive the benefits of any

directly nor indirectly compete, or invest in an entity or activity that is
competitive, with the Company and the Business.

     8.2 INTERESTED PARTY TRANSACTIONS. No future transaction between a Member

Member's or director's interest, Consent to the transaction.

cannot be Transferred unless the Members Consent to such Transfer. Any attempted
Transfer of any such Ownership Interest without compliance with this Section 9.1

sale, assignment, mortgage, hypothecation, gift, grant or transfer of any kind,

its consumer products business, and (b) USAD shall be permitted to (i) pledge
its Ownership Interest to its principal commercial lender, and (ii) transfer its

     9.2 ADMISSION OF ADDITIONAL MEMBERS. No person shall have any right as a
Member of the Company unless and until such person is admitted as a Member after
such approval as is required by, and in compliance with the other conditions set
forth in, this Section 9.2. A new Member may be admitted to the Company only
with the Consent of the Members and only if such person shall have executed a
counterpart of this Agreement or an appropriate supplement to it, in which such
person agrees to be bound by the terms and provisions of this Agreement as they
may be modified by that supplement. Any person so


                                       18
<PAGE>

admitted shall have all the rights and obligations of a Member hereunder

     9.3 INTEREST OF A NEW MEMBER. Upon receipt of any required Capital
Contribution from any newly admitted Member, such Member's Capital Contribution

         (a) CHD is hereby granted the option to purchase all of USAD's

(whether leased or owned) and all intellectual property covered by the USAD
License) (collectively, the "USAD ASSETS") for an aggregate purchase price
determined in accordance with the USAD Appraisal Procedure (as defined below).
In the event that any USAD Assets are joint use assets used for USAD businesses
other than the Business, the parties shall negotiate in good faith to enter into
such agreements as may be reasonably necessary to ensure an appropriate
transition period. For the purposes of this Agreement the term "USAD APPRAISAL
PROCEDURE" shall mean 6.5 times the sum of (i) USAD's average annual Net Profit
from the Company for the eight most recent fiscal quarters plus (ii) USAD's
average annual depreciation and amortization charged to the Company for such
eight quarters as part of manufacturing and distribution costs. An example of
the operation of the USAD Appraisal Procedure is set forth on Exhibit C hereto.
This option is exercisable by CHD at any time after the earliest to occur of the
following:

             (x) The fifth (5th) anniversary of the Effective Date;

             (y) Delivery to the Company of a Termination Notice (as defined in
Section 10.1 below) by USAD; provided that this option to purchase is exercised
within one hundred eighty (180) days thereafter; and

             (z) The bankruptcy or insolvency of USAD; provided that this option
to purchase is exercised within one hundred eighty (180) days thereafter.

         (b) USAD will not take any actions inconsistent with, or otherwise
impair or impede in any way, CHD's option to purchase as set forth in Section
9.4(a); it being understood that the submission or recommendation to USAD's
stockholders of a tender offer or other similar proposal to acquire USAD stock,
at any time prior to the exercise by CHD of such option to purchase, in all
instances consistent with the exercise by the directors of USAD of their
fiduciary duties and responsibilities, shall not be construed to be in violation
of this Section 9.4(b); it being further understood and agreed that the
foregoing shall not be construed to enable the directors of USAD to modify or
otherwise recommend against the USAD Appraisal Procedure, as a business deal, to
the extent the option to purchase is exercised by CHD. Subject to the foregoing,
 . USAD will take all actions that may be necessary on its part to ensure the
right of CHD to exercise the option to purchase, including recommending to
USAD's stockholders, if stockholder approval is necessary, that they approve the
consummation of the purchase transaction resulting from the exercise of the
option to purchase. CHD will be entitled to the remedy of specific performance
with respect to its rights contained in Section 9.4 (b).

         (c) USAD is hereby granted the option to require CHD to purchase all of
USAD's Ownership Interests and all of USAD's assets and properties used in the
Business (including, without limitation, all intellectual property covered by
the USAD License) for an aggregate purchase price determined in accordance with
the USAD Appraisal Procedure at any time after the tenth (10th) anniversary of
the Effective Date.

         (d) USAD is hereby granted the option to purchase all of CHD's
Ownership Interests and all of CHD's assets and properties used in the Business
(including, without limitation, all plant, equipment and warehouses (whether
leased or owned) and all intellectual property covered by the CHD License, but
excluding CHD's mining operation located in Green River, Wyoming and excluding
the Arm & Hammer name, brand and trademark) (collectively, the "CHD Assets") for
an aggregate purchase price determined in accordance with the CHD Appraisal
Procedure. In the event that any CHD Assets are joint use assets used for CHD
businesses other than the Business, the parties shall negotiate in good faith to
enter into such agreements as may be reasonably necessary to ensure an
appropriate transition period. For the purposes of this Agreement, the term "CHD
APPRAISAL PROCEDURE") shall mean 6.5 times the sum of (i) CHD's average annual
Net Profit from the Company for the eight most recent fiscal quarters, less the
Net Profit contribution attributed to the excluded assets referred to in the
foregoing parenthetical of this Section 9.4(d), plus (ii) CHD's average annual
depreciation and amortization charged to the Company for such eight quarters as
part of manufacturing and distribution costs. This option is exercisable by USAD
at any time after the earlier to occur of the following:

             (i) Delivery to the Company of a Termination Notice (as defined in
Section 10.1 below) by CHD; provided that this option to purchase is exercised
within one hundred eighty (180) days thereafter; and

             (ii) The bankruptcy or insolvency of CHD; provided that this option
to purchase is exercised within one hundred eighty (180) days thereafter.

         (e) If, following the exercise of CHD's option contained in Section
9.4(a), it is determined that the approval of USAD's stockholders is required in
order to complete the transaction and if such approval is not obtained, then the
following shall apply:

             (i) Section 9.4(c) shall cease to have any effect and will be
deemed to be deleted from this Agreement; and

             (ii) CHD will have the right, on six (6) months' prior notice to
the Company and USAD, to cancel the CHD License with respect to the Arm & Hammer
name, brand and trademark.

         (e) USAD hereby grants to CHD a security interest in all the assets and
properties covered by the option contained in Section 9.4(a) as security for
USAD's obligations thereunder, and USAD agrees to cooperate with CHD such that
all documentation needed to perfect such security interest will be in place
within ninety (90) days after the date hereof. The foregoing security interest
shall be expressly subject and subordinate to all security interests held by
Finova Capital Corporation, as agent (the "Agent"), for itself and for the other
lenders under



                                       20
<PAGE>

USAD's existing credit facility. USAD may grant to the Agent a security interest
in USAD's interest in the receivables and inventory of the Company.

         (a) As used herein "Change of Control" shall mean the occurrence of any
of the following events:

affiliate of a Member being the "beneficial owner" (as defined in Rule 13d-3
under said Act), directly or indirectly, of securities of CHD or USAD
constituting fifty percent (50%) or more of the total voting power represented
by CHD's or USAD's then outstanding voting securities; or

             (ii) a merger or consolidation of USAD or CHD with any other
corporation, other than a merger or consolidation which would result in the
voting securities of such party outstanding immediately prior thereto continuing
to represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) at least fifty percent (50%) of the total
voting power represented by the voting securities of such party or such
surviving entity outstanding immediately after such merger or consolidation; or
the adoption of a plan of complete liquidation or the sale or disposition by
USAD or CHD of at least fifty percent (50%) or more of such party's assets.

         (b) If, between the date hereof and the Trigger Date, USAD becomes
subject to a Change of Control, then this Agreement will terminate and USAD will
forthwith pay to CHD a fee of Ten Million Dollars ($10,000,000).

         (c) If, between the date hereof and the Trigger Date, CHD becomes
subject to a Change of Control, then this Agreement will terminate and CHD will
forthwith pay to USAD a fee of Three Million Dollars ($3,000,000).

         (d) If, between the Trigger Date and July 1, 2001, USAD becomes subject

Agreement and all of the transactions contemplated hereby and receive from CHD a
fee of Three Million Dollars ($3,000,000).

         (f) If either CHD or USAD becomes subject to a Change of Control
(either before or after July 1, 2001) and this Agreement is not terminated
pursuant to paragraphs (d) or (e), above, the following shall apply:

             (i) This Agreement and the other agreements referred to herein
shall not terminate but shall continue in full force and effect and be binding
upon any successor to the party subject to such Change of Control (the "COC
PARTY"); and

                                       21
<PAGE>

             (ii) Neither the COC Party nor any such successor shall be entitled
to deliver a Termination Notice.
