relating to such Spinco Plan from the trust relating to the corresponding NSI
Plan shall be recomputed, ab initio, as set forth in this Agreement but taking
into account the retention of any such Liabilities by such NSI Plan, and assets
shall be transferred by the trust relating to such Spinco Plan to the trust
relating to such NSI Plan so as to place each such trust in the position it
would have been in, had the initial asset transfer been made in accordance with
such recomputed amount of transferred Liabilities and assets.

<PAGE>

         (B)      TRANSFER OF SPECIFIC ASSETS

         The specific assets to be transferred from the NSI Master Pension Trust
to the Spinco Master Pension Trust shall be made up of cash and marketable
assets selected by NSI consistent with the objective of enabling Spinco to
implement prospectively an investment program for the Spinco Master Pension
Trust, but in no event shall NSI or the NSI Master Pension Trust be required to
incur unreasonable transaction costs in the process of transferring assets and
subsequently re-balancing the investment portfolio held by the NSI Master
Pension Trust. Furthermore, NSI shall not be required to transfer any specific
asset or any portion of any specific fund or investment manager account, and NSI
shall not transfer any amount of Spinco Common Stock that would place the Spinco
Pension Plans in violation of the employer stock acquisition limitations of
ERISA section 407; provided, however, that NSI shall transfer interests in group
annuity contracts held by the NSI Master Pension Trust to the extent such group
annuity contracts (in whole or in part, as the case may be) specifically cover
the accrued pension benefits of Transferred Individuals. In transferring
specific assets, NSI makes no representation as to the appropriateness of the
resulting asset allocation or investment performance resulting from the specific
assets transferred. By accepting the assets transferred, Spinco acknowledges
that it and not NSI is serving as the fiduciary for the Spinco Master Pension
Trust with respect to the determination and actual transfer of assets from the
NSI Master Pension Trust and that, acting as fiduciary for the Spinco Pension
Plans, Spinco further acknowledges that it is able to change the asset
allocation as it deems appropriate at any time. Once the assets have been
transferred to and received by the Spinco Master Pension Trust, such event shall
fully and finally foreclose any issue or matter of any nature whatsoever by
Spinco, the Spinco Master Pension Trust, the Spinco Pension Plans, or any other
trust(s) related to such Plans against NSI, the NSI Master Pension Trust, the
NSI Pension Plans, or any other trust(s) related to such Plans with respect to
the condition, identity, or value of such assets and Spinco shall fully
indemnify NSI, its employees, officers, directors, and the NSI Pension Plans,
the NSI Master Pension Trust, and any trustees or fiduciaries thereof regarding
any Liability or legal or regulatory issue of any nature with respect thereto.

3.4      GOVERNMENTAL COMPLIANCE

         Notwithstanding any provision of this Agreement to the contrary, in the
event that at any time any Governmental Authority challenges or seeks to prevent
the transfer of assets and Liabilities provided for in Sections 3.1 and 3.3, NSI
and Spinco shall reach such other agreement as may be mutually satisfactory to
NSI and Spinco respecting the matters covered by this Article III.

4.1      SAVINGS PLANS

         (A)      ASSUMPTION OF SPINCO SAVINGS PLANS AND RELATED LIABILITIES

         Effective no later than the Close of the Distribution Date, Spinco or a
member of the Spinco Group shall take all action necessary to assume and become
the plan sponsor of the Spinco Savings Plans and shall be responsible for all
Liabilities relating to the Spinco Savings Plans. The Spinco Savings Plans shall
recognize and maintain all contribution and investment elections made by
Transferred Individuals under the Spinco Savings Plans as such elections were
last in effect during the period immediately prior to the Distribution Date and
shall apply such elections under the Spinco Savings Plans for the remainder of
the period or periods for which such elections are by their terms applicable
(subject in all cases to applicable election change rights of the Transferred
Individuals).

         (B)      TRANSFER OF LIABILITIES UNDER NSI CORPORATE 401(K) PLAN

         Effective no later than the Close of the Distribution Date: (i) all
Liabilities to or relating to Retained Corporate Employees under the National
Service Industries Retirement and 401(k) Plan ("Corporate 401(k) Plan") shall
cease to be Liabilities of the Corporate 401(k) Plan and shall be assumed in
full and in all respects by one or more NSI Savings Plans; (ii) the appropriate
NSI Savings Plan(s) shall assume and be solely responsible for all ongoing
rights of or relating to these Retained Corporate Employees for future
participation (including the right to make contributions through payroll
deductions in the NSI Savings Plan(s); and (iii) the accounts of the Retained
Corporate Employees under the Corporate 401(k) Plan which are held by its
related trust shall be transferred to the account(s) of the appropriate NSI
Savings Plan under the NSI Master Savings Trust.

         (C)      SAVINGS PLAN TRUST

         Effective no later than the Close of the Distribution Date, Spinco
shall establish, or cause to be established, the Spinco Master Savings Trust
which shall be qualified under Code ss. 401(a), be exempt from taxation under
Code ss. 501(a)(1), and form part of the Spinco Savings Plans. Spinco shall,
prior to the end of the remedial amendment period for the Spinco Savings Plans,
apply for determination letters from the Internal Revenue Service that shall
provide that the Spinco Savings Plans and the Spinco Master Savings Trust
satisfy the requirements for qualification under Code sections 401(a) and
501(a), and Spinco shall take all actions necessary or appropriate to obtain
such letters.

         (D)      TRANSFER OF ASSETS

         Effective on a date selected by NSI, which is expected to be no later
than the Close of the Distribution Date (the "Savings Plans Transfer Date"), all
of the assets associated with and allocated to the accounts of each Spinco
Savings Plan under the NSI Master Savings Trust shall be transferred from the
NSI Master Savings Trust to the Spinco Master Savings Trust. If the

                                      -17-
<PAGE>

transfer of assets does not occur prior to the Close of the Distribution Date,
NSI and Spinco shall mutually reschedule the asset transfer date; provided,
however, such rescheduled date must occur not later than December 31, 2001.

         (E)      SPECIFIC STOCK FUNDS IN THE NSI AND SPINCO SAVINGS PLANS

         Effective no later than Immediately after the Distribution Date, a
Spinco Common Stock fund shall be added as an investment option to any NSI
Savings Plan or Spinco Savings Plan that has an NSI Common Stock fund. The
Spinco Common Stock fund in the NSI Savings Plans and the NSI Common Stock fund
in the Spinco Savings Plans are each referred to as a "Non-Employer Stock Fund"
with respect to the applicable Plan. Unless NSI and Spinco agree otherwise, each
Non-Employer Stock Fund shall be maintained under the respective Plan through
December 31, 2002. After such date, NSI and Spinco agree to cooperate with each
other with respect to the disposition of the stock when either party decides to
liquidate or otherwise terminate the Non-Employer Stock Fund in its Savings
Plans. In the absence of any agreement regarding such liquidation, the
liquidation of the Non-Employer Stock Fund shall be made in a ratable manner
over a period of six months. Furthermore, at any time that NSI or Spinco decides
to sell or otherwise dispose of any amount of shares in their Non-Employer Stock
Fund (other than sales or dispositions required to satisfy the investment
directions from participants, for liquidity reasons or other general operational
purposes), the selling party shall follow the procedures of Section 4.2 (except
to the extent waived in writing by an authorized representative of the other
party). The NSI Savings Plans and the Spinco Savings Plans shall each provide
that, after the Distribution Date, no new contributions may be invested in, and
no amounts may be transferred from other investment options to the Non-Employer
Stock Fund under the respective Plan; but, subject to the terms of the
respective Plan, participants may direct that amounts be transferred out of the
Non-Employer Stock Fund to other investment options. To the extent the parties
determine it is necessary to preserve the tax status of the Distribution under
the Code, the NSI Savings Plans shall provide that no earnings or dividends
under its Non-Employer Stock Fund may be reinvested in Spinco Common Stock and
the Spinco Savings Plans shall provide that no earnings or dividends under its
Non-Employer Stock Fund may be reinvested in NSI Common Stock; provided,
however, this requirement shall not prohibit such earnings and dividends from
remaining in the applicable Non-Employer Stock Fund as cash or as an amount that
is invested in any non-stock investment in such fund.

4.2      NON-EMPLOYER STOCK FUND PROCEDURES

         (A)      APPLICATION OF PROCEDURES

         Whenever NSI or Spinco (the "Selling Party") desires to sell or
otherwise dispose of any or all of the shares of stock of the other party (the
"Notice Party") in their respective Non-Employer Stock Funds (other than sales
or dispositions required to satisfy the investment directions from participants,
for liquidity reasons or other general operational purposes), the Selling Party
shall follow the procedures for selling or otherwise disposing of such stock set
forth in this Section 4.2, and the Notice Party shall be entitled to advance
notice and a right of

                                      -18-
<PAGE>

first refusal to purchase such stock all as provided in this Section 4.2. The
provisions of this Section 4.2 shall be subject to the provisions of Section
7.8.

         (B)      RIGHT OF FIRST REFUSAL AND NOTICE PROCEDURES

         When the Selling Party desires to sell or otherwise dispose of any or
all of the shares of stock in their Non-Employer Stock Fund (other than sales or
dispositions required to satisfy the investment directions from participants,
for liquidity reasons or other general operational purposes), the Selling Party
shall first offer such stock for sale to the Notice Party by delivering to the
Notice Party's Chief Financial Officer, or his or her designee, a written offer
of such shares of stock for sale to the Notice Party. The offer for sale to the
Notice Party shall designate the total number of shares of stock desired to be
sold (the "Offered Shares") and any special terms of sale, if the Offered Shares
will not be sold on the market.

         (C)      PROCEDURES AFTER NOTICE IS GIVEN

         The Notice Party shall within 30 days after receipt of notice advise
the Selling Party in writing whether it desires to purchase the Offered Shares
(which notice must confirm that it agrees to purchase all of the Offered
Shares), and the terms upon which such purchase would be consummated. Failure to
so notify the Selling Party shall be deemed a rejection of the offer, and the
Selling Party after the close of the 30-day period may sell or otherwise dispose
of the Offered Shares in its sole discretion. In the event that the Notice Party
advises the Selling Party of its acceptance of the offer for sale, such
acceptance shall specify a purchase date (the "Purchase Date") that is not less
than ten nor more than 30 days after the date of such acceptance, and on which
the New York Stock Exchange is scheduled to be open for trading. The purchase
price paid for the Offered Shares and the terms and conditions of the payment
shall be negotiated and agreed upon between the Selling Party and the Notice
Party before the Purchase Date. If the Selling Party and the Notice Party have
not agreed upon the price and the terms and conditions for payment by the
Purchase Date, the Notice Party shall have the right to purchase all of the
Offered Shares for cash immediately following the close of the New York Stock
Exchange on the Purchase Date, at a price per Offered Share equal to its closing
price on the New York Stock Exchange (but with any adjustment for the size of
the block that is necessary, in the judgment of the valuation expert designated
by NSI and Spinco for this purpose, to accomplish the sale at fair market
value). If the Notice Party does not purchase and pay for all of the Offered
Shares on the Purchase Date, it shall be deemed to have completely rejected the
offer and all of the Offered Shares may be sold or otherwise disposed of by the
Selling Party in its sole discretion.

                       ARTICLE V HEALTH AND WELFARE PLANS

5.1      ASSUMPTION OF HEALTH AND WELFARE PLAN LIABILITIES

         (A)      ASSUMPTION BY SPINCO

         Effective no later than the Close of the Distribution Date, Spinco
shall establish or cause to be established, the Spinco Health and Welfare Plans.
Immediately after the Distribution Date, all Liabilities for or relating to
Transferred Individuals under the NSI Health and Welfare Plans, shall cease to
be Liabilities of NSI or the NSI Health and Welfare Plans and shall be assumed
by Spinco and the corresponding Spinco Health and Welfare Plans. Thus, Spinco
and the Spinco Health and Welfare Plans shall be responsible for all Liabilities
that pertain to Transferred Individuals regardless of when incurred, including
all reported claims that are unpaid, all incurred but not reported claims as of
the Close of the Distribution Date, and all claims incurred after the Close of
the Distribution Date that pertain to Transferred Individuals under the NSI
Health and Welfare Plans and the Spinco Health and Welfare Plans. Spinco shall
be required to make all payments due or payable to Transferred Individuals under
the appropriate Spinco Health and Welfare Plans for the period beginning
Immediately after the Distribution Date, including all reported claims that are
unpaid and all incurred but not reported claims as of the Close of the
Distribution Date. All treatments which have been pre-certified for or are being
provided on an on-going basis to a Transferred Individual under the NSI Health
and Welfare Plans as of the Close of the Distribution Date shall continue to be
provided without interruption under the appropriate Spinco Health and Welfare
Plan until such treatment is concluded or discontinued pursuant to applicable
plan rules and limitations, and Spinco and the Spinco Health and Welfare Plans
shall be responsible for all Liabilities relating to, arising out of, or
resulting from such pre-certified or on-going treatments as of the Close of the
Distribution Date. Notwithstanding the preceding provisions of this Section 5.1,
neither Spinco nor a Spinco Health and Welfare Plan shall assume any Liability
with respect to: (i) a claim incurred on or prior to the Close of the
Distribution Date for which NSI or an NSI Health and Welfare Plan has insurance
coverage, and (ii) any benefit claim for which NSI is responsible under Section
5.4. Furthermore, NSI shall pay to Spinco a portion of any prescription drug
rebates received by NSI under the NSI Major Medical Plan which relate to periods
prior to the Distribution Date, which portion shall be determined by the number
of Transferred Individuals compared to the total number of participants in the
NSI Major Medical Plan as of the Distribution Date.

         (B)      CERTAIN AUDIT PROCEDURES WITH RESPECT TO HEALTH AND WELFARE
                  PLANS

         At periodic intervals beginning Immediately after the Distribution
Date, NSI and Spinco shall examine their respective payments and receipts for
health and welfare coverages to ascertain whether NSI has mistakenly made or
received payments for coverages with respect to Transferred Individuals and
whether Spinco has mistakenly made or received payments for coverages with
respect to participants and beneficiaries in the NSI Health and Welfare Plans
(other than Transferred Individuals). If any such mistaken payments have been
made or received by NSI or Spinco, such mistaken payments and receipts shall
first be netted against each other by NSI and Spinco and thereafter such net
payments or net receipts shall be further

                                      -20-
<PAGE>

netted against the other party's net payments or net receipts. The party with
the remaining amount of mistaken payments shall transfer such amount in cash to
the other party at such time or times as agreed upon by NSI and Spinco, but not
less than semi-annually. Furthermore, at periodic intervals beginning
Immediately after the Distribution Date, NSI and Spinco shall examine the
payment of benefits and claims, and reimbursements for expenses, by their
respective Health and Welfare Plans to ascertain whether any NSI Health and
Welfare Plan has mistakenly paid claims or benefits, or reimbursed expenses,
with respect to Transferred Individuals and whether any Spinco Health and
Welfare Plan has mistakenly paid claims or benefits, or reimbursed expenses,
with respect to participants and beneficiaries in the NSI Health and Welfare
Plans (other than Transferred Individuals). If any such mistaken payments or
reimbursements have been made by any NSI or Spinco Health and Welfare Plan, such
mistaken payments and reimbursements shall be netted against the other
corresponding Health and Welfare Plan's mistaken payments and reimbursements.
The Health and Welfare Plan with the remaining amount of mistaken payments and
reimbursements shall transfer such amount in cash to the other party's
corresponding Health and Welfare Plan at such time or times as agreed upon by
NSI and Spinco, but not less than semi-annually.

5.2      VENDOR CONTRACTS

         (A)      ASO CONTRACTS, GROUP INSURANCE POLICIES, HMO AGREEMENTS, AND
                  LETTERS OF UNDERSTANDING

         (1)      Before the Distribution Date, NSI shall, in its sole
discretion, take such steps as are necessary under each ASO Contract, Group
Insurance Policy, HMO Agreement, letter of understanding, and arrangement in
existence as of the date of this Agreement to permit Spinco to participate in
the terms and conditions of such ASO Contract, Group Insurance Policy, HMO
Agreement, letter of understanding, or arrangement from Immediately after the
Distribution Date through December 31, 2002. Alternatively, NSI shall take such
steps as are necessary to arrange for an ASO Contract, Group Insurance Policy,
HMO Agreement, letter of understanding, or arrangement covering Spinco that
mirrors substantively that covering NSI. This mirror arrangement shall apply for
all or a portion of such period, as necessary under the circumstances. NSI, in
its sole discretion, may cause one or more of its ASO Contracts, Group Insurance
Policies, HMO Agreements, letters of understanding, and arrangements into which
NSI enters after the date of this Agreement to allow Spinco to participate in
the terms and conditions thereof. Nothing contained in this Section 5.2(a) shall
preclude NSI from choosing to enter into ASO Contracts, Group Insurance
Policies, HMO Agreements, letters of understanding, or other arrangements with
new or different vendors; provided, until December 31, 2002, NSI shall give
Spinco advance notice of any decision to change or add vendors. Furthermore,
nothing contained in this paragraph (1) shall require NSI to use more than its
reasonable best efforts in complying with the provisions of the first and second
sentence of this paragraph (1).

         (2)      NSI shall have the right to determine, and shall promptly
notify Spinco of, the manner in which Spinco's participation in the terms and
conditions of ASO Contracts, Group Insurance Policies, HMO Agreements, letters
of understanding and arrangements as set forth above shall be effectuated;
provided, however, NSI shall use its best efforts to accommodate any

                                      -21-
<PAGE>

reasonable needs communicated to NSI by Spinco that relate thereto. Such terms
and conditions shall include the financial and termination provisions,
performance standards, methodologies, auditing policies, quality measures,
reporting requirements, and target claims. Spinco hereby authorizes NSI to act
on its behalf to extend to Spinco the terms and conditions of the ASO Contracts,
Group Insurance Policies, HMO Agreements, and letters of understanding and
arrangements. Spinco shall fully cooperate with NSI in such efforts, and, for
periods through December 31, 2002, Spinco shall not perform any act or fail to
take any action that would prejudice NSI's efforts and financial arrangements
under the Health and Welfare Plans (other than taking reasonable steps to enter
into replacement ASO Contracts, Group Insurance Policies, HMO Agreements, and
letters of understanding and arrangements for periods after December 31, 2002,
which steps shall not, unless the parties otherwise agree, commence publicly
prior to January 1, 2002).

         (B)      PAYMENT AND EFFECT OF CHANGE IN RATES

         NSI and Spinco shall use their reasonable best efforts to cause each of
the insurance companies, HMOs, paid provider organizations and third-party
administrators providing services and benefits under the NSI Health and Welfare
Plans and the Spinco Health and Welfare Plans to maintain the premium and/or
administrative rates based on the aggregate number of participants in the NSI
Health and Welfare Plans and the Spinco Health and Welfare Plans, from the Close
of the Distribution Date through December 31, 2001, separately rated or adjusted
for the demographics, experience or other relevant factors related to the
covered participants of NSI and Spinco, respectively. To the extent they are not
successful in such efforts, NSI and Spinco shall each bear the revised premium
or administrative rates for health and welfare benefits attributable to the
individuals covered by their respective Health and Welfare Plans. The assistance
that NSI shall provide Spinco pursuant to this subsection (b) shall be provided
subject to the terms and conditions of the Transition Services Agreement.

5.3      NSI SHORT-TERM DISABILITY ARRANGEMENTS

         Any final determinations made by NSI with respect to short-term
disability claims by Transferred Individuals prior to the Distribution Date
shall be final and binding. NSI shall transfer to Spinco, effective Immediately
after the Distribution Date, and Spinco shall assume responsibility for (i)
administering all short-term disability claims incurred by Transferred
Individuals before the Close of the Distribution Date that are administered by
NSI as of the Close of the Distribution Date, and (ii) all Liabilities under any
NSI short-term disability arrangements to Transferred Individuals as of the
Close of the Distribution Date, in the same manner, and using the same methods
and procedures, as NSI used in determining and paying such claims. Effective
Immediately after the Distribution Date, Spinco shall have sole discretionary
authority to make any necessary determinations with respect to such claims,
including entering into settlements with respect to such claims, and shall be
solely responsible for any costs, Liabilities or related expenses of any nature
whatsoever related to such claims, payments or obligations.

                                      -22-

5.4      RETIREE HEALTH AND LIFE INSURANCE BENEFITS

         Effective immediately after the Distribution Date, Spinco shall adopt a
Spinco Plan or Plans to provide any retiree medical or life insurance benefits
that are required to be provided to Transferred Individuals. Any retiree medical
or life insurance benefits provided shall be substantially identical to the
retiree medical or life insurance benefits that would have been provided under
an NSI Plan for such individuals, subject to the right of Spinco to amend or
terminate any such retiree benefits. In the case of any individual who is not a
Transferred Individual, NSI will retain the liability for providing any retiree
medical or life insurance benefits required to be provided to such individual,
subject to the right of NSI to amend or terminate any such retiree benefits.

5.5      COBRA AND HIPAA

         Effectively Immediately after the Distribution Date, Spinco or a member
of the Spinco Group shall be responsible for administering compliance and
providing coverage in accordance with the health care continuation coverage
requirements for "group health plans" under Title X of the Consolidated Omnibus
Budget Reconciliation Act of 1985, as amended ("COBRA"), and the portability
requirements (including the requirements for issuance of certificates of
creditable coverage) under the Health Insurance Portability and Accountability
Act of 1996 with respect to all Transferred Individuals and other employees and
former employees of Spinco or a member of the Spinco Group and any beneficiaries
and dependents thereof who experience a COBRA qualifying event or loss of
coverage under the Spinco Health and Welfare Plans after the Close of the
Distribution Date. Effective Immediately after the Distribution Date, Spinco or
a member of the Spinco Group shall be responsible for filing all necessary
employee change notices with respect to these persons identified in the previous
sentence in accordance with applicable law.

5.6      LEAVE OF ABSENCE PROGRAMS

         Effective Immediately after the Distribution Date, Spinco or a member
of the Spinco Group shall assume sole responsibility for the administration and
compliance of all leaves of absences and related programs (including compliance
with the Family and Medical Leave Act of 1993, as amended) affecting Transferred
Individuals.

5.7      POST-DISTRIBUTION  TRANSITIONAL ARRANGEMENTS

         (A)      CONTINUANCE OF ELECTIONS, CO-PAYMENTS, AND MAXIMUM BENEFITS

         (1)      Spinco shall cause the Spinco Health and Welfare Plans to
recognize and maintain all coverage and contribution elections made by
Transferred Individuals under the NSI Health and Welfare Plans, as such
elections were last in effect during the period immediately prior to the
Distribution Date, and shall apply such elections under the Spinco Health and
Welfare Plans for the remainder of the period or periods for which such
elections are by their terms applicable (subject to applicable election change
rights). NSI shall cause the claims administrator for the NSI Health and Welfare
Plans to transfer to the claims administrator for the Spinco Health and Welfare
Plan all data necessary to maintain such coverage and elections.

                                      -23-
<PAGE>

         (2)      Spinco shall cause the Spinco Health and Welfare Plans to
recognize and give credit for (A) all amounts applied to deductibles,
out-of-pocket maximums, and other applicable benefit coverage limits with
respect to such expenses which have been incurred by Transferred Individuals
under the NSI Health and Welfare Plans for the remainder of the benefit limit
year in which the Distribution occurs, and (B) all benefits paid to Transferred
Individuals under the NSI Health and Welfare Plans, during and prior to the
benefit limit year in which the Distribution occurs, for purposes of determining
when such persons have reached their maximum benefits under the Spinco Health
and Welfare Plans.

         (3)      Spinco shall recognize and cover under the Spinco Health and
Welfare Plans all eligible employee groups covered by the NSI Health and Welfare
Plans (pertaining to Transferred Individuals) as of the Close of the
Distribution Date (determined under the applicable Plan documents).

         (4)      Spinco shall (A) provide coverage to Transferred Individuals
under the Spinco Health and Welfare Plans without the need to undergo a physical
examination or otherwise provide evidence of insurability, and (B) recognize and
maintain all irrevocable assignments, elections and beneficiary designations
made by Transferred Individuals in connection with their life insurance coverage
under the NSI Health and Welfare Plans and any predecessor plans.

         (B)      ADMINISTRATION

                  (1)      Coordination of Benefits for Spouses and Dependents

         Effective as of the earlier of the first January 1 or the first
applicable change in status (as defined under the Spinco Health and Welfare
Plans) that occurs after the Distribution Date, Spinco shall cause the Spinco
Health and Welfare Plans to permit eligible Transferred Individuals to cover
their lawful spouses as dependents if such lawful spouses are active or retired
NSI employees (but were not otherwise covered as a dependent under the NSI
Health and Welfare Plans or other NSI Plans due to their previous status as both
employee and dependent of an NSI employee). As of the earlier of the first
January 1 or the first applicable status change (as defined under the Spinco
Health and Welfare Plans) that occurs Immediately after the Distribution Date,
NSI shall cause the NSI Health and Welfare Plans to permit eligible NSI
employees to cover their lawful spouses as dependents if such lawful spouses are
active or retired Spinco employees. All benefits provided under any such Health
and Welfare Plans to a lawful spouse or dependent of the other company's
employees shall be coordinated pursuant to the terms and conditions of the
applicable NSI and Spinco Plans.

                  (2)      Health Care Financing Administration Data Match

         Effective Immediately after the Distribution Date, Spinco shall assume
all Liabilities relating to, arising out of or resulting from claims verified by
NSI or Spinco under the Health Care Financing Administration data match reports
that relate to Transferred Individuals. Spinco and NSI shall share all
information necessary to verify Health Care Financing Administration data match
reports regarding Transferred Individuals. Spinco shall not change any employee

                                      -24-
<PAGE>

identification numbers assigned by NSI without notifying NSI of the change and
the new employee identification number.

         (C)      NSI REIMBURSEMENT PLANS

         To the extent any Transferred Individual contributed to an account
under the NSI Reimbursement Plans during the calendar year that includes the
Distribution Date, effective Immediately after the Distribution Date, Spinco
shall recognize any such Transferred Individual's account balance, determined as
of the Close of the Distribution Date, and Spinco shall thereafter be solely
responsible for making any and all payments relative to such account balance of
the Transferred Individual for all claims during such calendar year under the
applicable Spinco Reimbursement Plan. As provided in Section 5.7(a), all
elections by Transferred Individuals in effect immediately prior to the
Distribution Date shall continue and be recognized by Spinco, and the
Distribution alone shall not be considered an event that gives any participant
the right to change any prior election. As soon as practicable after the
Distribution Date, NSI shall calculate as of the Close of the Distribution Date
the aggregate net balance in the accounts of Transferred Individuals under the
NSI Reimbursement Plans, expressed relative to the contributions received from
such Transferred Individuals. If the contributions received from a Transferred
Individual exceed the reimbursements made to or on behalf of such Transferred
Individual, the Transferred Individual shall be deemed to have a positive
account balance. In turn, if the contributions received from a Transferred
Individual are less than the reimbursements made to or on behalf of such
Transferred Individual, the Transferred Individual shall be deemed to have a
negative account balance. If the aggregate net balance in the accounts of all
such Transferred Participants is a positive number, then NSI shall pay this
amount in cash to Spinco as soon as practicable after the Distribution Date, and
if the aggregate net balance in the accounts of all such Transferred
Participants is a negative number, then Spinco shall pay this amount in cash to
NSI as soon as practicable after the Distribution Date.

5.8      APPLICATION OF ARTICLE V TO THE SPINCO GROUP

         Any reference in this Article V to "Spinco" shall include a reference
to another member of the Spinco Group when and to the extent Spinco has caused
the other member of the Spinco Group to (a) become a party to an ASO Contract,
Group Insurance Policy, HMO Agreement, letter of understanding or arrangement
associated with a Spinco Health and Welfare Plan, (b) become a self-insured
entity for the purposes of one or more Spinco Health and Welfare Plans, (c)
assume all or a portion of the Liabilities or the administrative
responsibilities with respect to benefits which arose before the Close of the
Distribution Date under any NSI Health and Welfare Plan and which were expressly
assumed by Spinco pursuant to this Agreement, or (d) take any other action,
extend any coverage, assume any other Liability or fulfill any other
responsibility that Spinco would otherwise be required to take under the terms
of this Article V, unless it is clear from the context that the particular
reference is not intended to include another member of the Spinco Group. In all
such instances in which a reference in this Article V to "Spinco" includes a
reference to another member of the Spinco Group, Spinco shall be responsible to
NSI for ensuring that the other member of the Spinco Group complies with the
applicable terms of this Agreement and that the Transferred Individuals employed
by such member of the Spinco Group shall have the same rights and entitlements
to benefits under the applicable Spinco Health and Welfare Plans that the
Transferred Individual would have had, if he or she had instead been employed by
Spinco.

6.1      ASSUMPTION OF OBLIGATIONS

         Consistent with the principles set forth in Article II and except as
otherwise specifically provided herein, effective no later than the Close of the

sponsor of and assume all Liabilities with respect to any Executive Program that
is a Spinco Stand-Alone Plan and shall assume and be solely responsible for all

notwithstanding any failure by Spinco to complete its obligations under this
Article.

6.2      ANNUAL INCENTIVE AWARDS

         Prior to the Distribution Date, NSI shall pay to participants
(including Transferred Individuals) any amounts earned under the Annual

Distribution Date, Spinco shall establish the Spinco Annual Incentive Plan

appropriate.

         (A)      AWARD 4 (FOR THE PERFORMANCE PERIOD 9/1/99-8/31/02)

who are Corporate Office employees for the performance period ending August 31,
2002, effective as of August 31, 2001, a determination shall be made by NSI of
the extent to which the Awards have been earned for the performance period as of
such date and no further amounts shall be earned by such Transferred Individuals
after that date. The amounts earned (if any) under the Awards as of August 31,
2001 shall be payable by NSI as promptly as practicable after the amounts are
determined.

         With respect to Awards under Award 4 for Transferred Individuals other
than Corporate Office employees, such Awards shall be assumed by Spinco and
shall be paid, to the extent earned, after the close of the performance period
ending on August 31, 2002, under and in accordance with the terms of the Spinco
Long-Term Incentive Plan; provided, however, that Spinco will make such
adjustments to the financial goals, targets, payments and forms of payments as
Spinco in its sole discretion deems appropriate to reflect the Distribution.

         (B)      STOCK OPTIONS

         The treatment of outstanding Awards described in this Section 6.3 shall
apply to Transferred Individuals, including Transferred Individuals who have
terminated employment or who are compensated under a payroll which is
administered outside the 50 United States, its

                                      -26-
<PAGE>

territories and possessions, and the District of Columbia; provided, however, if
such treatment is not legally permitted, or results in adverse consequences for
NSI, any of its affiliates or the Transferred Individual, as determined by NSI
in its sole discretion, NSI may determine, in its sole discretion, to provide
for a different treatment.

         Effective Immediately after the Distribution Date, each Award or grant
consisting of an option, regardless of the date of the grant, under an NSI Stock
Incentive Plan that is outstanding as of the Close of the Distribution Date for
all Transferred Individuals and all Spinco non-employee directors who were
previously non-employee directors of NSI shall be converted to options for
Spinco Common Stock with the same material terms and conditions under the Spinco
Stock Incentive Plan, and shall be transferred to the recordkeeper of the Spinco
Stock Incentive Plan. As soon as practicable after the Distribution Date, the
number of options and the exercise price for such options converted to options
for Spinco Common Stock shall be determined in accordance with the Conversion
Formula. Such converted Spinco stock option grants shall continue to vest and
become exercisable under the Spinco Stock Incentive Plan in accordance with the
terms of the original grant under the NSI Stock Incentive Plan. Spinco shall be
the obligor with respect to such options and shall be solely responsible for all
stock option grants and payments under the Spinco Stock Incentive Plan, with
respect to, but not limited to, recordkeeping, administrative costs and fees,
payroll taxes, plan maintenance, option exercise and related tax filings. Spinco
shall, as soon as practicable after the Distribution Date provide each
Transferred Individual with an agreement or notice relating to the Transferred
Individual's options under the Spinco Stock Incentive Plan.

         (C)      RESTRICTED STOCK AWARDS

                  (1)      Determination of Status of Restricted Stock

         Effective as of the record date for the Distribution, NSI shall
determine the extent to which shares of restricted stock awarded under an NSI
Stock Incentive Plan pursuant to a restricted stock award agreement (A) have
begun to vest as a result of an applicable stock price target having been
achieved and have been registered in the name of the holder of such restricted
stock on the books of NSI's transfer agent, but remain unvested and subject to a
substantial risk of forfeiture (the "Granted Restricted Stock"), and (B) have
not begun to vest and are not registered in the name of the holder of such
restricted stock on the books of NSI's transfer agent, because the applicable
stock price targets in the restricted stock award agreement have not been
reached (the "Ungranted Restricted Stock").

                  (2)      Treatment of Granted Restricted Stock

         All executives (including Transferred Individuals) who hold shares of
Granted Restricted Stock shall receive the distribution of shares of Spinco
Common Stock on such shares of Granted Restricted Stock. All shares of Spinco
Common Stock received with respect to such Granted Restricted Stock shall be
subject to the same restrictions, terms and conditions as apply to the Granted
Restricted Stock pursuant to the restricted stock award agreement; provided,
however, that continued employment with Spinco or a member of the Spinco Group
or NSI or a member of the NSI Group shall be considered continued employment
under the restricted stock

                                      -27-
<PAGE>

award agreement. NSI and Spinco agree to notify the other party when a holder of
such restricted stock terminates employment prior to the date such restricted
stock is fully vested and no longer subject to a substantial risk of forfeiture.

                  (3)      Treatment of Ungranted Restricted Stock

         All executives (including Transferred Individuals) holding shares of
Ungranted Restricted Stock shall not receive the distribution of Spinco Common
Stock on such shares of Ungranted Restricted Stock. Effective Immediately after
the Distribution Date, all Ungranted Restricted Stock for all Transferred
Individuals shall be equitably converted to restricted stock Awards for Spinco
Common Stock under the Spinco Stock Incentive Plan, subject to the same
restrictions and the same material terms and conditions as under the restricted
stock award agreement; provided, that the number of shares and the stock price
targets under the converted restricted stock award agreements shall be equitably
revised to reflect the Distribution and the conversion of the Award to Spinco
Common Stock and Spinco Common Stock price targets.

                  (4)      Issuance of New Agreements

         As soon as practicable after the Distribution Date, NSI and Spinco
shall cooperate to replace each existing restricted stock award agreement held
by a Transferred Individual with two restricted stock award agreements: one
agreement with respect to the Granted Restricted Stock that becomes restricted
stock in both NSI and Spinco and the other agreement with respect to the
Ungranted Restricted Stock that is converted to a restricted stock Award of
Spinco Common Stock under the Spinco Stock Incentive Plan.

6.4      EMPLOYEE STOCK PURCHASE PLAN

         It is intended that Spinco will establish an employee stock purchase
plan that is substantially similar to the National Service Industries, Inc.
Employee Stock Purchase Plan and that the NSI Common Stock, and Spinco Common
Stock distributed with respect to such stock, held for Transferred Individuals
will be transferred to a recordkeeper for the Spinco Plan, provided, however,
Spinco, in its sole discretion, shall determine when such Plan shall become
effective and may change the terms of such Plan as it deems appropriate.

6.5      DEFERRED COMPENSATION PLANS

         (A)      ASSUMPTION OR ESTABLISHMENT OF SPINCO DEFERRED COMPENSATION
                  PLANS

         Effective no later than the Close of the Distribution Date, Spinco
shall take all necessary actions to assume, become plan sponsor of, and be
solely responsible for all Liabilities with respect to, the Deferred
Compensation Plans that are Spinco Stand-Alone Plans. Effective no later than
the Close of the Distribution Date, Spinco shall also establish the Spinco
Deferred Compensation Plans that are Spinco Mirror Plans, and the amounts
credited to the accounts of Transferred Individuals under the NSI Deferred
Compensation Plans shall be transferred to the applicable Spinco Deferred
Compensation Plans.

                                      -28-
<PAGE>

         The Transferred Individuals' termination of employment with the NSI
Group as a result of the Distribution shall not constitute a termination of
employment for purposes of the NSI or Spinco Deferred Compensation Plans. All
elections by the Transferred Individuals that were controlling under the terms
of the applicable NSI Deferred Compensation Plan prior to the Distribution shall
continue under the applicable Spinco Plan until changed under the terms of such
Plan. All investment choices of Transferred Individuals under the NSI or Spinco
Deferred Compensation Plans shall also be continued in effect; provided,
however, that any account balance that is deemed to be invested in whole or in
part in phantom shares of NSI Common Stock shall be converted into deemed
investments in phantom shares of Spinco Common Stock in an equitable manner
determined by Spinco. Nothing herein shall restrict NSI's or Spinco's rights to
amend or terminate their respective Plans in the future.

         (B)      TRANSFER OF CORPORATE-OWNED LIFE INSURANCE

         No later than the Close of the Distribution Date, NSI shall transfer
and assign to Spinco all of the corporate-owned life insurance policies owned by
NSI or an affiliate of NSI that have been held by NSI to help fund its
obligations under the Deferred Compensation Plans that are being assumed or
adopted by Spinco; provided, however, that such transfer shall not occur (or
shall be modified in an appropriate manner) unless NSI has received a
satisfactory opinion of legal counsel that such transfer of corporate-owned life
insurance will not jeopardize the current tax treatment of such policies.

6.6      SUPPLEMENTAL RETIREMENT BENEFIT PLANS

         Effective no later than the Close of the Distribution Date, NSI and
Spinco shall take all necessary actions (a) to allow Spinco to adopt and assume,

respect to the supplemental retirement plans previously maintained by the
Holophane Corporation; and (b) to allow Spinco to establish the Spinco
Supplemental Pension Plan and the Spinco Supplemental Retirement Plan for

under the Supplemental Pension Plan of National Service Industries, Inc. and the
Supplemental Retirement Plan for Executives of National Service Industries, Inc.

6.7      BENEFITS PROTECTION TRUST AND EXECUTIVE BENEFITS TRUST

         Effective no later than the Close of the Distribution Date, NSI and
Spinco shall take all actions necessary to allow Spinco or a member of the
Spinco Group to adopt and assume, amend as appropriate, and replace NSI as a
party to and grantor under, the National Service Industries, Inc. Benefits
Protection Trust and the National Service Industries, Inc. Executive Benefits
Trust ("Trusts").

6.8      SEVERANCE PROTECTION AGREEMENTS

         Effective Immediately after the Distribution Date, Spinco shall enter
into severance protection agreements with the Transferred Individuals listed in

                                      -29-

protection agreements with the Transferred Individuals.

6.9      EMPLOYMENT AGREEMENTS

         Effective Immediately after the Distribution Date, Spinco shall enter
into employment agreements with the Transferred Individuals listed in Appendix E

be solely responsibly for all Liabilities related to the Spinco employment
agreements with the Transferred Individuals.

6.10     AUTOMOBILE PROGRAM

         As of the Close of the Distribution Date, Spinco shall assume all of
NSI's Liabilities and obligations with respect to the motor vehicles leased by
NSI for Transferred Individuals pursuant to lease agreements under any NSI
Executive automobile program.

6.11     OTHER EXECUTIVE BENEFITS/PROGRAMS

         Effective no later than the Close of the Distribution Date, Spinco
shall establish Plans that are substantially similar to the following NSI Plans
and other executive benefits: Executive physical program, corporate matching
gift program, automobile allowance policy. Spinco shall assume all Liabilities

         Effective not later than the Close of the Distribution Date, Spinco

substantially identical in all Material Respects to the National Service
Industries, Inc. Non-Employee Director Deferred Stock Unit Plan, and Spinco
shall assume and be solely responsible for all Liabilities under the NSI
Non-Employee Director Deferred Stock Unit Plan relating to individuals who
become non-employee directors of Spinco (and certain former non-employee
directors of NSI). The deferred stock units of NSI Common Stock relating to
non-employee directors of Spinco shall be converted into deferred stock units of
Spinco Common Stock in an equitable manner as determined by Spinco.

         (B)      NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

         Effective not later than the Close of the Distribution Date, Spinco
shall establish the Spinco, Inc. Non-Employee Directors' Stock Option Plan that

shall be treated as provided in Section 6.3(b).

7.5      PLAN AUDITS

         (A)      AUDIT RIGHTS WITH RESPECT TO THE ALLOCATION OR TRANSFER OF
                  PLAN ASSETS

         The allocation of Pension Plan assets and liabilities pursuant to
Section 3.3 shall, at the election of Spinco, be audited on behalf of both NSI
and Spinco by an actuarial and benefit consulting firm mutually selected by the
parties; provided, however, that no audit shall be permitted after the date of
the pension plan asset transfer, in the case of the Pension Plans. The scope of
such audit shall be limited to the accuracy of the data and the accuracy of the
computation and adherence to the methodology specified in this Agreement and,
except as set forth in the penultimate sentence of this Section 7.5(a), such
audit shall not be binding on the parties. The actuarial and benefit consulting
firm shall provide its report to both NSI and Spinco. No other audit shall be
conducted with respect to the allocation of Plan assets and no issue of any
nature whatsoever may be raised by Spinco once the transfer of assets has been
completed. Subject to the following two sentences, no transfer of assets shall
occur unless and until Spinco agrees to the allocation of assets. To the extent
such audit recommends a change to the value of assets allocated to a Spinco Plan
of less than 5%, the original determination shall be binding on the parties and
shall not be subject to the dispute resolution process provided in Section 7.16.
To the extent such audit recommends such a change of 5% or more (a "Significant
Allocation Change"), any unresolved dispute between the parties as to whether
and how to make any change in response to such recommendation shall be subject
to the dispute resolution process provided in Section 7.16. Spinco shall pay or
shall be responsible for the payment of the full costs of such audit; provided,
however, that in the event such audit recommends a Significant Allocation Change
and such recommendation is attributable to variances in actuarial assumptions or
simplification or modification of the allocation calculated by NSI, NSI shall be
responsible for the full costs of such audit.

and their duly authorized representatives, shall have the right to conduct
audits at any time upon reasonable prior notice, at their own expense, with
respect to all information provided to it or to any Plan recordkeeper or
third-party administrator by the other party. Subject to Sections 7.5(a) and
7.5(b)(2), the party conducting the audit shall have the sole discretion to

being audited and of any benefit providers and third parties with whom the party
being audited has a relationship, or agents of such party, to the extent any
such persons are affected by or addressed in this Agreement (collectively, the
"Non-parties"). The party being audited shall, upon written request from the
auditing party, provide an individual (at the auditing party's expense) to
supervise any audit of any Non-party. The auditing party shall be responsible
for supplying, at its expense, additional personnel sufficient to complete the
audit in a reasonably timely manner.

         (C)      AUDITS REGARDING VENDOR CONTRACTS

         From Immediately after the Distribution Date through December 31, 2002,
NSI and Spinco and their duly authorized representatives shall have the right to
conduct joint audits with respect to any vendor contracts that relate to both
the NSI Health and Welfare Plans and the Spinco Health and Welfare Plans. The
scope of such audits shall encompass the review of all correspondence, account
records, claim forms, canceled drafts (unless retained by the bank), provider
bills, medical records submitted with claims, billing corrections, vendor's
internal corrections of previous errors and any other documents or instruments
relating to the services performed by the vendor under the applicable vendor
contracts. NSI and Spinco shall agree on the performance standards, audit
methodology, auditing policy and quality measures and reporting requirements
relating to the audits described in this Section 7.5(c) and the manner in which
costs incurred in connection with such audits will be shared.

         (D)      AUDIT ASSISTANCE

         To the extent that either NSI or Spinco is required to respond to any
Governmental Authority, vendor or recordkeeper audit, or otherwise conducts an
audit with respect to any provision or obligation of the other party under this
Agreement, NSI or Spinco, whichever is applicable, shall be required to fully
cooperate with the audit, including providing such records

                                      -33-

arise by reason of such audit. The party being audited shall provide the
auditing party's representatives with reasonable access during normal business
hours to its operations, computer systems and paper and electronic files, and
provide workspace to its representatives. To the extent the results of an audit
result in any correction to the Liabilities involving any Transferred
Individuals, Spinco shall be solely responsible for all such costs and expenses
associated with such Liabilities and any related corrections.

         All beneficiary designations, authorizations for the release of
information and rights to reimbursement made by or relating to Transferred

effect under the corresponding Spinco Plans until such beneficiary designations,
authorizations or rights are replaced or revoked by, or no longer apply, to the
relevant Transferred Individual.

7.7      REQUESTS FOR INTERNAL REVENUE SERVICE RULINGS AND UNITED STATES
         DEPARTMENT OF LABOR OPINIONS

         Spinco shall cooperate fully with NSI on any issue relating to the
transactions contemplated by this Agreement for which NSI elects to seek a
determination letter or private letter ruling from the Internal Revenue Service
or an advisory opinion from the United States Department of Labor. NSI shall
cooperate fully with Spinco with respect to any request for a determination
letter or private letter ruling from the Internal Revenue Service or advisory

Spinco Plans relating to the transactions contemplated by this Agreement.

7.8      FIDUCIARY AND RELATED MATTERS

         The parties acknowledge that NSI will not be a fiduciary with respect
to the Spinco Plans and that Spinco will not be a fiduciary with respect to the
NSI Plans. The parties also acknowledge that neither party shall be deemed to be
in violation of this Agreement if it fails to comply with any provisions hereof
based upon its good faith determination that to do so would violate any
applicable fiduciary duties or standards of conduct under ERISA or other
applicable law. Notwithstanding any other provision in this Agreement, the
parties may take such actions as necessary or appropriate to effectuate the
terms and provisions of this Agreement.

7.9      NO THIRD-PARTY BENEFICIARIES; NON-TERMINATION OF EMPLOYMENT

         This Agreement is not intended and shall not be construed as to confer
upon any Person other than the parties hereto any rights or remedies hereunder.
No provision of this Agreement or the Distribution Agreement shall be construed
to create any right, or accelerate entitlement, to any compensation or benefit
whatsoever on the part of any Transferred Individual or other future, present,
or former employee of the NSI Group or the Spinco Group under any NSI Plan or
Spinco Plan or otherwise. Without limiting the generality of the foregoing,
except as expressly provided in this Agreement: (i) neither the Distribution nor
the termination of the

                                      -34-
<PAGE>

Participating Company status of a member of the Spinco Group shall cause any
employee to be deemed to have incurred a termination of employment which
entitles such individual to the commencement of benefits under any of the NSI
Plans, any of the Spinco Plans, or any of the Individual Agreements; and (ii)
nothing in this Agreement other than those provisions specifically set forth
herein to the contrary shall preclude Spinco, at any time after the Close of the

reducing, or otherwise altering in any respect any Spinco Plan, any benefit
under any Plan or any trust, insurance policy or funding vehicle related to any
Spinco Plan.

7.10     COLLECTIVE BARGAINING

         To the extent any provision of this Agreement is contrary to and
violates the provisions of any applicable collective bargaining agreement to
which NSI or any affiliate of NSI is a party, the terms of such collective
bargaining agreement shall continue to apply to the affected employees. Should
any provision of this Agreement be deemed to relate to a topic determined by an
appropriate authority to be a mandatory subject of collective bargaining, NSI or
Spinco may be obligated to bargain with the union representing affected
employees concerning those subjects.

7.11     CONSENT OF THIRD PARTIES

third party (such as a vendor) and such consent is withheld, NSI and Spinco
shall use their reasonable best efforts to implement the applicable provisions
of this Agreement to the full extent practicable. If any provision of this
Agreement cannot be implemented due to the failure of such third party to
consent, NSI and Spinco shall negotiate in good faith to implement the provision
in a mutually satisfactory manner. The phrase "reasonable best efforts" as used
in this Agreement shall not be construed to require the incurrence of any
non-routine or unreasonable expense or liability or the waiver of any right.

except to the extent specifically agreed by Spinco and NSI.

7.14     RELATIONSHIP OF PARTIES

or any third party as creating the relationship of principal and agent,
partnership or joint venture between the parties, it being understood and agreed
that no provision contained herein, and no act of the parties, shall be deemed
to create any relationship between the parties other than the relationship set
forth herein.

any Person (other than a Person who is a member of the Spinco or NSI Group) and
which is related solely to NSI's exercise of its fiduciary responsibility for
the investment of the assets of the NSI Plans prior to the Distribution Date (or
prior to the Pension Plan Spinoff Date for purposes of the NSI Pension Plans and
prior to the Savings Plan Transfer Date for purposes of the NSI Savings Plans).
In addition, effective on the Distribution Date, NSI agrees to indemnify and
hold harmless each member of the Spinco Group and each of their respective
officers, directors, employees and agents and the Spinco Plans and any related
trusts, including the Spinco Pension Trust and the trustees thereof, from and
against any and all Indemnifiable Expenses arising solely out of a claim which
is made by any Person (other than a Person who is a member of the Spinco or NSI
Groups) and which is related solely to NSI's exercise of its fiduciary
responsibility for the investment of the assets of the NSI Plans prior to the
Distribution Date (or prior to the Pension Plan Spinoff Date for purposes of the
NSI Pension Plans and prior to the Savings Plan Transfer Date for purposes of
the NSI Savings Plans).

         If any action is brought or any claim is made against a party or person
in respect of which indemnity may be sought pursuant to this Section 7.17 (the
"Indemnitee"), the Indemnitee shall, within twenty (20) days after the receipt
of information indicating that an action or claim is likely, notify in writing
the party from whom indemnification is sought (the "Indemnitor") of the
institution of the action or the making of the claim, and the Indemnitor shall
have the right,

                                      -36-
<PAGE>

and at the request of the Indemnitee, shall have the obligation, to assume the
defense of the action or claim, including the employment of counsel. If the
Indemnitor assumes the defense of the action or claim, the Indemnitor shall be
entitled to settle the action or claim on behalf of the Indemnitee without the
prior written consent of the Indemnitee, unless such settlement would, in
addition to the payment of money, materially affect the ongoing business or
employment of the Indemnitee.

         The Indemnitee shall have the right to interpret the provisions of its
own Plans and to employ its own counsel, but the fees and expenses of that
counsel shall be the responsibility of the Indemnitee unless: (i) the employment
of that counsel shall have been authorized in writing by the Indemnitor in
connection with the defense of the action or claim; (ii) the Indemnitor shall
not have employed counsel to have charge of the defense of such action or claim;
or (iii) such Indemnitee shall have reasonably concluded that there may be
defenses available to it which are different from or additional to those
available to the Indemnitor (in which case the Indemnitor shall not have the
right to direct any different defense of the action or claim on behalf of the
Indemnitee). The Indemnitee shall, in any event, be kept fully informed of the
defense of any such action or claim. Except as expressly provided above, in the
event that the Indemnitor shall not previously have assumed the defense of an
action or claim, at such time as the Indemnitor does assume the defense of the
action or claim, the Indemnitor shall not thereafter be liable to any Indemnitee
for legal or other expenses subsequently incurred by the Indemnitee in
investigating, preparing or defending against such action or claim.

         Anything in this Section 7.17 to the contrary notwithstanding, the
Indemnitor shall not be liable for any settlement of any claim or action
effected without its written consent; provided, however, that if after due
notice the Indemnitor refuses to defend a claim or action, the Indemnitee shall
have the right to defend and/or settle such action, and the Indemnitee shall not
be precluded from making a claim against the Indemnitor for reasonable expenses
and liabilities resulting from such defense and/or settlement in accordance with
this Section 7.17.

         Notwithstanding the foregoing provisions of this Section 7.17, there
may be particular actions or claims which reasonably could result in both
parties being liable to the other under the indemnification provisions of this
Agreement. In such events, the Parties shall endeavor, acting reasonably and in
good faith, to agree upon a manner of conducting the defense and settlement of
the action or claim with a view to minimizing the legal expenses and associated
costs that might otherwise be incurred by the parties, such as, by way of
illustration only, agreeing to use the same legal counsel.

         The indemnification provisions of this Section 7.17 shall not inure to
the benefit of any third party. By way of illustration only, an insurer who
would otherwise be obligated to pay any claim shall not be relieved of the
responsibility with respect thereto, or, solely by virtue of the indemnification
provisions, hereof, have any subrogation rights with respect thereto, it being
expressly understood and agreed that no insurer or any other third party shall
be entitled to a "windfall" (i.e., a benefit they would not be entitled to
receive in the absence of the indemnification provisions) by virtue of these
indemnification provisions.

7.18     W-2 MATTERS

         Pursuant to the alternative procedure set forth in Internal Revenue
Service Rev. Proc. 96-60, Spinco will assume NSI's obligations to furnish Forms
W-2 to all Transferred Individuals for the year in which the Distribution Date
occurs. NSI will provide to Spinco the information not available to Spinco
relating to periods ending on the Distribution Date necessary for Spinco to
prepare and distribute Forms W-2 to Transferred Individuals for the year in
which the Distribution Date occurs, which will include all remuneration earned
by Transferred Individuals before the Distribution Date and Forms W-4 provided
to NSI by Transferred Individuals to the extent that Spinco is not already in
possession of such information. Spinco shall prepare and distribute such forms.
To the extent permitted by applicable law, in particular Code Sections
3121(a)(1) and 3306(b)(1), Spinco shall be deemed a successor employer to NSI
with respect to Transferred Individuals for purposes of calculating the annual
wage limitation to which state and federal payroll taxes apply.

7.19     CONFIDENTIALITY

         Except as required by applicable law, for the purpose of satisfying any
obligation under this Agreement or with the consent of the other party, neither
NSI nor Spinco shall disclose to any Person (other than members of the NSI Group
or the Spinco Group) any information (including, but not limited to, information
regarding fees, expenses, assets, Liabilities and Plan terms) relating to the
NSI Plans, Spinco Plans or Transferred Individuals. Each of NSI and Spinco shall
be permitted to disclose such information within the NSI Group and Spinco Group
only to the extent reasonably necessary in the ordinary course of business.

7.20     NOTICES

         Any notice, demand, claim, or other communication under this Agreement
shall be in writing and shall be given in accordance with the provisions for
giving notice under the Distribution Agreement.

7.21     INTERPRETATION

         Words in the singular shall be held to include the plural and vice
versa and words of one gender shall be held to include the other genders as the
context requires. The terms "hereof," "herein," and "herewith" and words of
similar import shall, unless otherwise stated, be construed to refer to this
Agreement as a whole (including all Appendices hereto) and not to any particular
provision of this Agreement. The word "including" and words of similar import
when used in this Agreement shall mean "including, without limitation," unless
the context otherwise requires or unless otherwise specified. The word "or"
shall not be exclusive.

7.22     SEVERABILITY

         The provisions of this Agreement are severable and should any provision
hereof be void, voidable or unenforceable under any applicable law, such
provision shall not affect or invalidate any other provision of this Agreement,
which shall continue to govern the relative rights and duties of the parties as
though such void, voidable or unenforceable provision were not a part hereof.

7.23     GOVERNING LAW/EXECUTION

         This Agreement shall be construed in accordance with, and governed by,
the laws of the State of Delaware without regard to the conflicts of law rules
of such state, may not be assigned by either party without the prior written
consent of the other, and shall bind and inure to the benefit of the parties
hereto and their respective successors and permitted assignees. This Agreement
may not be amended or supplemented except by an agreement in writing signed by
NSI and Spinco. This Agreement may be executed in one or more counterparts, each
of which shall be deemed an original instrument, but all of which together shall
constitute one and the same Agreement.

                            APPENDIX D FOREIGN PLANS

         This Appendix D describes the principles under which Foreign Plans
shall be treated. For purposes of this Appendix, outside the U.S. means outside
the 50 United States, its territories and possessions, and the District of
Columbia, and employed outside the U.S. means compensated under a payroll which
is administered outside the United States.

D.1      PLANS COVERING ONLY EMPLOYEES OF NSI OR SPINCO

         Effective as of the Close of the Distribution Date or such later date
as may be required by applicable law, union, or works council agreement, any
Foreign Plan that covers only individuals employed outside the U.S. by the NSI
Group shall be the sole responsibility of the NSI Group and no member of the
Spinco Group shall have any Liability with respect to such a Plan; and any
Foreign Plan that covers only individuals employed outside the U.S. by the
Spinco Group shall be the sole responsibility of the Spinco Group and no member
of the NSI Group shall have any Liability with respect to such a Plan.

D.2      PLANS COVERING EMPLOYEES OF BOTH NSI AND SPINCO

         (A)      TERMINATION OF PARTICIPATION

         To the extent legally permitted and except as otherwise provided
herein, effective as of the Close of the Distribution Date, or as soon as
practicable thereafter, Spinco and each other applicable member of the Spinco
Group shall cease to be a Participating Company in each Foreign Plan maintained
by NSI or the NSI Group and each other applicable member of the NSI Group shall
cease to be a Participating Company in each Foreign Plan maintained by the
Spinco Group. NSI and Spinco recognize that because of the requirements of local
law or administrative considerations, a transition period extending beyond the
Close of the Distribution Date may be required during which NSI or Spinco may
continue to participate in each other's Foreign Plans. During such transition
period, NSI and Spinco agree to cooperate in handling any and all matters with
respect to the Foreign Plans.

         (B)      MIRROR PLANS

                  (1)      Effective Immediately after the Distribution Date,
Spinco shall adopt, or cause to be adopted, Foreign Plans for the benefit of
employees of the Spinco Group employed outside the United States who are
eligible to participate in NSI Foreign Plans and shall cause such Spinco Foreign
Plans to be substantially identical in all Material Features to the
corresponding NSI Foreign Plans as in effect on the Distribution Date.
Notwithstanding the preceding sentence - (i) Spinco may satisfy this requirement
by extending coverage to such individuals under a Foreign Plan of the Spinco
Group which was in effect before the Distribution Date and which is, with
respect to all Material Features, at least equal to the corresponding NSI
Foreign Plan, and (ii) Spinco is not required to adopt a defined benefit pension
plan for the benefit of its Canadian employees (but instead shall make an
equitable adjustment to the defined contribution plan covering these employees).

                                      -44-
<PAGE>

                  (2)      Effective Immediately after the Distribution Date,
NSI shall adopt, or cause to be adopted, Plans for the benefit of any employees
of the NSI Group employed outside the United States who are eligible to
participate in Spinco Plans and shall cause such Plans to be substantially
identical in all Material Features to the corresponding Spinco Foreign Plans as
in effect on the Distribution Date; provided, however, that NSI may satisfy this
requirement by extending or continuing coverage to such individuals under an NSI
Foreign Plan of the NSI Group which was in effect before the Distribution Date.

                  (3)      The continuation by NSI or Spinco of separate
employment terms and conditions for employees previously covered by the other
entity's Plans shall not continue beyond the time legally required.

         (C)      TRANSFER OF ASSETS

         As of the Close of the Distribution Date, NSI and Spinco will use their
reasonable best efforts to ensure that, to the extent legally permitted: (i)
Liabilities of the Foreign Plans of NSI relating to Transferred Individuals
shall be assumed by the appropriate Foreign Plans of Spinco; and (ii) an
appropriate portion of any assets of the Foreign Plans of NSI shall be
transferred to the appropriate Foreign Plans of Spinco, and vice versa.

D.3      SEVERANCE ISSUES

         If under applicable law, any Transferred Individual employed outside
the U.S. is deemed to have incurred a termination of employment as a result of
the Distribution or any other transaction contemplated by the Distribution
Agreement or this Agreement, which entitles such individual to receive any
payment or benefit under any Foreign Plan, governmental plan or arrangement or
pursuant to any law or regulation, including severance benefits, notwithstanding
such individual's continued employment by the Spinco Group, then Spinco shall be
liable for any such payment or benefit and, notwithstanding any other provision
hereof, to the extent legally permitted, appropriate adjustments shall be made
to the treatment of such individual during such continued employment, including
not giving such individual credit for prior service and/or treating such
individual as having been newly hired immediately after such deemed termination,
for purposes of all applicable Foreign Plans. Liability with respect to such
payments shall be the responsibility of Spinco.

D.4      LEGALLY PERMITTED

         For purposes of this Appendix D, "legally permitted" means permitted
under the laws of the country, the labor union, works council, or collective
agreement without adverse consequences to NSI, Spinco or Transferred
Individuals, as determined by NSI, in its sole discretion, including mandated
waiting periods before which working conditions (including benefits) cannot be
changed, and upon receiving required agreement from individual employees and/or
Plan trustees, foundation boards and members, and any other organizations having
a recognized right to determine or affect benefits and/or funding of the Plan.

                                 LEASE AGREEMENT

         THIS LEASE AGREEMENT (this "Lease") made and entered into on this 30th
day of November, 2001, by and between NATIONAL SERVICE INDUSTRIES, INC., a
California corporation ("Landlord"), and ACUITY BRANDS, INC., a Delaware
corporation ("Tenant");

                                   WITNESSETH:

         For and in consideration of the mutual covenants set forth below,
Landlord and Tenant do hereby agree as follows:

         1.       LEASE OF PREMISES. Subject to and upon the terms and
conditions herein provided, Landlord does hereby rent, lease, and demise to
Tenant approximately 50,000 square feet of space (the "Premises"), which
Premises includes that office space occupied by employees of Tenant on the date
of the spin-off of Tenant from Landlord located on the 2nd, 7th and 8th Floors
of that certain building located at 1420 Peachtree Street, NE, Atlanta, Georgia
(the "Building"), together with the common areas of the Building, including but
not limited to, the underground parking facilities, lobby and 4th Floor of the
Building, together with all and singular the rights, privileges, and
appurtenances thereto belonging or in any wise appertaining.

         2.       TERM AND RENTALS. The term of this Lease shall be for a period
of four (4) months, commencing on the 1st day of December, 2001, and terminating
on the 31st day of March, 2002; provided that Tenant shall have the right, upon
one month written notice to Landlord, to extend the term of the Lease for a
period one month at the monthly rental rate set forth in the following sentence.
For the entire term hereof, Tenant agrees to pay Landlord as monthly rental
hereunder the sum of One Hundred Twenty Thousand Dollars and No/100 Dollars
($120,000). All rental provided for hereunder shall be due and payable on the
first day of each month, with rent being prorated for partial months.

         3.       USE. Tenant shall use and occupy the Premises solely for
general office use, and no other purpose. Tenant shall comply with all laws
applicable to the use, occupancy and condition of the Premises. Tenant shall not
conduct or permit any activities on or about the Premises that would constitute
a nuisance or otherwise interfere with other occupants of the Building.

<PAGE>

         4.       REPAIRS. Landlord shall, for the entire term of this Lease,
maintain and keep in good working order, repair, and condition the structural
integrity of the Building, including the roof and exterior walls.

         During the term of this Lease, except as otherwise provided above with
respect to the maintenance and repair requirements of Landlord, Tenant will
maintain the Premises in as good order and repair as at commencement of this
Lease (ordinary wear and tear excepted), will remove or cause to be removed any
and all rubbish and refuse matter from the Premises, and at the termination of
the term, will deliver up the Premises in substantially as good condition,
order, and repair as at commencement of this Lease, except for ordinary wear and
tear and damage by fire or other casualties.

         5.       INSURANCE. Landlord shall maintain during the term of this
Lease insurance against loss or damage to all of the improvements on the
Premises resulting from fire, extended coverage, vandalism, malicious mischief,
earthquake, flood, collapse, and other all risk perils in commercially
reasonable amounts. Tenant shall, at Tenant's sole cost and expense, but for the
mutual benefit of Landlord and Tenant, maintain workers' compensation coverage
as required by law and general public liability insurance coverage against
claims for personal injury, death, or property damage occurring upon, in, or
about the Premises, such insurance to afford protection to the limit of not less
than Three Million Dollars ($3,000,000) combined single limit coverage and name
Landlord as additional insured. In addition, Tenant shall maintain commercially
reasonable insurance coverage against loss or damage to Tenant's personal
property located upon the Premises.

         Insurance required hereunder must be written by a company authorized to
do business in Georgia, subject to the approval of Landlord, which approval
shall not be unreasonably withheld. Each policy of insurance will be endorsed to
provide that Landlord will receive at least thirty (30) days' prior written
notice of any cancellation of, or material change in, said policy. Tenant shall
not cause any insurance to be cancelled nor permit any insurance to lapse
without thirty (30) days' prior written notice to Landlord. A certificate
evidencing liability insurance required to be maintained by Tenant hereunder
naming Landlord as an additional insured shall be delivered to Landlord upon the
execution of this Lease.

         6.       CASUALTY LOSS. In the event the Building is damaged or
destroyed during the term hereof by fire, storm, tornado, or other casualty of
nature, or otherwise, so as to render the Premises wholly untenantable and unfit
for use, then and in such event, Landlord or Tenant may, at the option of
either, immediately terminate said Lease. If neither party terminates, then
Landlord shall proceed with reasonable speed and dispatch to repair and
reconstruct the Building so damaged or destroyed and shall restore the same to
its former tenantable condition, in which event, the terms, provisions, and
operative effect of this Lease shall be unaffected by said fire, storm, tornado,
or other casualty of nature, except that the rent due and payable hereunder
shall abate and cease for the period during which the restoration of the
Premises is being completed, but shall become immediately payable as herein
provided at such time as the Premises becomes tenantable, as determined in
Landlord's reasonable discretion. Notwithstanding anything in this

<PAGE>

Lease to the contrary, there shall be no abatement of rent after a casualty to
the extent that the damage occurred due to fault or neglect on the part of
Tenant, its employees, servants, agents, representatives, or invitees.

         7.       WAIVER OF SUBROGATION. Tenant and Landlord each hereby waive
any and all rights of recovery against the other, or against the officers,
employees, agents, and representatives of the other, for loss of or damage to
such waiving party or its property or the property of others under its control
or any loss or damage, including consequential loss, to the Premises, or
contents thereof belonging to either, caused by any risk required to be insured
against hereunder, regardless of whether such risk was actually insured.

         8.      SIGNS. Tenant shall not erect any signs in or upon the
Premises or the Building or the property on which they are located without
Landlord's prior approval in writing. Tenant shall be liable for the payment of
any municipal charges or minor privilege tax levied by reason of the erection
and maintenance of such signs. At the termination of this Lease, Tenant shall
remove all signs installed by Tenant and any damage resulting from the
installation and/or removal of such sign will be repaired by Tenant.

         9.      DEFAULT BY TENANT. Tenant shall be in default under this Lease
in the event that it (A) fails to pay rent for ten (10) days after it is due
hereunder, or (B) fails to perform or comply with any other provision hereof for
a period of thirty (30) days after receipt of written notice thereof from
Landlord; provided that if, such failure cannot reasonably be cured within
thirty (30) days, then Tenant shall have an additional period of time, not to
exceed sixty (60) days, to cure such failure, so long as Tenant has commenced
and is diligently pursuing appropriate actions to cure such failure. Upon a
default by Tenant, Tenant's right to the further possession of the Premises
shall terminate and Landlord shall become and be entitled to immediate
possession of the Premises, provided Landlord shall so elect, but not otherwise.
Landlord shall thereupon immediately have the full right of re-entry upon the
Premises, by force or otherwise, to the extent permitted by the applicable law
then in force, and without formal notice or demand, and without liability of any
kind; and also the right, but not the obligation, to re-let the Premises for any
unexpired balance of the term, and collect the rent therefor. In the event of
such re-letting by Landlord, the re-letting shall be for such duration (which
may extend beyond the unexpired balance of the term) and on such other terms,
conditions, and rental as Landlord may deem proper, and the proceeds that may be
collected from the same, less the expense of re-letting (including reasonable
leasing costs, fees, and commissions and reasonable costs of renovating the
Premises), shall be applied upon Tenant's rental obligation as set forth in this
Lease for the unexpired portion of the Lease term. Tenant shall be liable for
any balance that may be due under this Lease, although Tenant shall have no
further right of possession of the Premises. Such re-entry by Landlord and any
