Auditors' Report
REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
To the Plan Administrator of
Zep Manufacturing Company
Profit Sharing/401(k) Retirement Plan:
We have audited the accompanying statements of net assets available for benefits
of ZEP MANUFACTURING COMPANY PROFIT SHARING/401(k) RETIREMENT PLAN as of
December 31, 1997 and 1996, and the related statement of changes in net assets
available for benefits, with fund information, for the year ended December 31,
1997. These financial statements are the responsibility of the Plan's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 1997 and 1996, and the changes in net assets available for benefits
for the year ended December 31, 1997, in conformity with generally accepted
accounting principles.
Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The fund information in the statement of
changes in net assets available for benefits is presented for the purpose of
additional analysis rather than to present the changes in net assets available
for benefits of each fund. The fund information has been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, is fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

ZEP MANUFACTURING COMPANY
PROFIT SHARING/401(k) RETIREMENT PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 1997 AND 1996
1. PLAN DESCRIPTION
The following is a brief description of the Zep Manufacturing Company
Profit Sharing/401(k) Retirement Plan (the "Plan") of Zep Division of
National Service Industries, Inc. of Georgia and Zep Division of Zep
Manufacturing Company (together, the "Employer"). Both National Service
Industries, Inc. of Georgia and Zep Manufacturing Company are wholly owned
subsidiaries of National Service Industries, Inc. ("NSI"). This description
is provided for informational purposes only. Participants should refer to
the plan agreement for more complete information.
General
The Plan is a defined contribution plan established under the provisions of
Section 401(a) of the Internal Revenue Code ("IRC"). The Plan covers all
salaried, commissioned, and union and nonunion hourly employees of the
Employer with at least six months of service and who have attained the age
of 21. The Plan is subject to the provisions of the Employee Retirement
Income Security Act of 1974, as amended.
In November 1997, the Employer acquired Pure Corporation ("Pure").
Effective November 17, 1997 the Plan was amended to provide that all years
of service with Pure be counted toward the eligibility and vesting of Pure
employees in the Plan. Further, all Pure employees who were eligible to
participate in the Pure Corporation Employees' Savings and Stock Ownership
Plan as of November 17, 1997 were immediately eligible to participate in
the Plan.
Contributions
Participants may elect to contribute between 1% and 15% of before-tax
compensation, as defined in the Plan, subject to certain limitations under
the IRC.
The Employer makes a profit-sharing contribution to the Plan for salaried,
commissioned, and nonunion hourly employees in the amount of 5% of net
profits, as defined, plus an amount which represents the same percentage of
total annual compensation of all hourly paid employees who are participants
of the Plan as the 5% of net profits bears to the total annual compensation
of the salaried and commissioned employees who are participants under this
Plan. This amount is multiplied by a fraction which represents the
relationship between the annual compensation of all salaried, commissioned,
and nonunion hourly employees to the annual compensation of all employees
who are qualifying participants in the Plan. Annual compensation included
for each participant shall not exceed $40,000. An additional amount may be
contributed at the discretion of the board of directors of NSI.
The Employer also makes a profit-sharing contribution to the Plan for the
union employees, which is calculated in a similar manner as that described
above.
<PAGE>
Page 7
Employer contributions are allocated to all participants who are actively
employed on November 30 of the plan year and who have a year of service, as
defined, during the plan year which contains such November 30. Allocations
are made based on each qualifying participant's compensation relative to
the compensation of all qualifying participants, with a limitation on
compensation considered of $40,000.
Vesting
Participants are always fully vested in their individual contributions.
Vesting of employer contributions occurs on an increasing scale, ranging
from 20% vesting after three years of service, as defined, to 100% vesting
after seven years of service. Nonvested employer contributions are
forfeited upon a participant's withdrawal from the Plan and are allocated
to remaining participants in the same manner as contributions.
Administration
The responsibility for administration of the Plan rests with the Plan's
profit-sharing committee, which is appointed by the board of directors of
NSI. All administrative expenses of the Plan were paid by the Employer
during the year ended December 31, 1997.
Participants' Accounts
Individual accounts are maintained for each of the Plan's participants to
reflect the particular participant's contributions and related employer
contributions as well as the participant's share of the Plan's income and
any related investment management fees and expenses.
The Plan's investment fund balances are expressed in units. At December 31,
1997 and 1996, 12,146,977 and 11,359,095 units, respectively, were assigned
to plan participants. Unit values for each investment fund were as follows
at December 31, 1997 and 1996:
1997 1996
Balanced Fund.............................. $33.18 $26.40
Diversified Equity Fund.................... 14.04 12.05
Stable Value Fund.......................... 12.07 11.31
NSI Stock Fund............................. 19.61 14.52
International Fund......................... 4.82 5.01
Index Fund................................. 89.56 N/A
Small Company Fund......................... 11.21 N/A
Investment in Master Trust
Under a trust agreement dated September 1, 1993, as amended, Wachovia Bank
of Georgia, N.A. was appointed trustee of the NSI Defined Contribution
Plans Master Trust (the "NSI DC Trust"). Effective January 1, 1998, INVESCO
Trust Company has been appointed trustee of the NSI DC Trust.
The Plan's assets are commingled in the NSI DC Trust together with the
assets of certain defined contribution plans of other NSI divisions. The
investments of the NSI DC Trust are subject to certain administrative
guidelines and limitations as to type and amount of securities held.
Certain fund assets are allocated to selected independent investment
managers to invest under these general guidelines.

Investment Options
The separate investment options made available under the Plan may be
changed, eliminated, or modified from time to time by the investment
committee of the NSI DC Trust. Participants make their investment elections
in 5% increments, with changes allowed on a daily basis.
The separate investment options offered by the Plan are as follows:
o Diversified Equity Fund. This fund is a diversified stock fund
designed to invest in a broad range of common stocks providing capital
growth.
o Stable Value Fund. This is a fixed income fund designed to provide a
steady level of current income while focusing on preservation of
principal.
o Balanced Fund. This fund is invested in a changing mix of high-quality
stocks and bonds. The fund is designed to provide capital growth and
current income while limiting the risk of principal loss.
o NSI Stock Fund. This fund is invested in NSI common stock, although it
may hold other short-term investments from time to time. A participant
may not direct more than 50% of his/her account balance to be invested
in this fund.
o International Fund. This fund is invested in the stock of non-U.S.
companies and is designed to provide long-term growth.
o Index Fund. This fund (offered beginning June 1997) is invested in all
of the stocks in the Standard & Poor's 500 Composite Stock Price
Index.
o Small Company Growth Fund. This fund (offered beginning June 1997) is
invested in small or emerging companies that show potential for
increased size and profitability. The fund seeks little or no current
income.
Loans to Participants
The Plan permits loans to participants up to the lesser of 50% of the
participant's vested account balance or $50,000. A participant has up to
five years to repay the principal and interest. Loan processing fees are
charged directly to the participant's account. Interest rates on loans to
participants are determined based on market rates, as determined by the
plan administrator. The interest rate as of December 31, 1997 was 9.5%.
Loan issuances and repayments are included in intraplan transfers in the
accompanying statement of changes in net assets available for benefits.
Interest on loans is included in the net gain from investment in NSI DC
Trust and is allocated to each investment fund based on participants'
investment elections.
Benefits
A participant is entitled to receive the distribution of his/her vested
account balance upon death, disability, or retirement (age 65 or age 55
with ten years of credited service). These benefits are payable in a
lump-sum amount or can be paid in installments at the election of the
participant. The vested portion of the participant's employer contributions
is generally distributable on the first day of the first month following
the later of his/her termination date or sixty-fifth birthday. If this
vested portion is less than $5,000, then the participant may elect to have
his/her interest distributed immediately in a lump sum.
Benefits are payable in cash, except that any portion of a participant's
account balance which is invested in the NSI Stock Fund is distributed in
the form of shares of NSI common stock, with fractional shares paid in
cash.
<PAGE>
Page 9
Hardship withdrawals may be made upon proven financial hardship of a
participant, as defined in the plan agreement and as approved by the Plan's
retirement committee.
Plan Termination
Although the Employer intends for the Plan to be permanent, the Plan
provides that the Employer has the right to discontinue contributions or to
terminate the Plan at any time. In the event of plan termination, each
participant shall be vested in the balance of his/her account and his/her
proportionate share of any future adjustments or forfeitures.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Accounting
The accounts of the Plan are maintained by the trustee on the cash basis of
accounting. The accompanying financial statements have been prepared using
the accrual method of accounting by application of memorandum entries. The
preparation of financial statements in conformity with generally accepted
accounting principles requires the Plan's management to use estimates and
assumptions that affect the accompanying financial statements and
disclosures. Actual results could differ from these estimates.
Investment Valuation
Investments of the NSI DC Trust, except for the guaranteed investment
contracts ("GICs"), are stated at fair value, as determined by the trustee
from quoted market prices. Securities traded on a national exchange are
valued at the last reported sales price on the last business day of the
plan year; investments traded in the over-the-counter market and listed
securities for which no sale was reported on the last day of the plan year
are valued at the last reported bid price.
GICs included in the NSI DC Trust are fully benefit-responsive and are
therefore carried at contract value (cost plus accrued interest) in the
accompanying financial statements in accordance with Statement of Position
94-4. At December 31, 1997 and 1996, contract value approximates fair
value. At December 31, 1997, the weighted average crediting interest rate
was 7%. For the year ended December 31, 1997, the annual yield on the GICs
held by the NSI DC Trust was 6.9%. For certain of the GICs held by the NSI
DC Trust, crediting interest rates may be changed if certain events occur,
such as early retirements, plant closings, etc., but in no case are
adjusted to a rate less than 0%.
GICs are subject to credit risk based on the ability of the insurance
company to meet interest or principal payments, or both, as they become
due.
Certain GICs included in the NSI DC Trust are synthetic; that is, the NSI
DC Trust owns certain fixed income securities and the contract issuer
provides a "wrapper" that guarantees a fixed rate of return and provides
benefit responsiveness. At December 31, 1997, the fair value of the
underlying assets of the synthetic GICs (determined from quoted market
prices) and the value of the related wrapper contracts were $42,945,334 and
$(825,875), respectively.

4. TAX STATUS
The Plan has received a favorable determination letter from the Internal Revenue
Service dated May 21, 1996 stating that the Plan was designed in accordance with
plan design requirements as of that date. The Plan has been amended since
receiving the determination letter. However, the plan administrator believes
that the Plan is currently designed and is being operated in compliance with the
applicable requirements of the IRC. Therefore, the plan administrator believes
that the Plan was qualified and that the related trust was tax-exempt as of
December 31, 1997 and 1996.
