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,  1994 and 1993 and the related  statements of changes in net assets
available for benefits for the year ended  December 31,  1994 and the four-month
period  ended   December 31,   1993.   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  ZEP
Manufacturing Company  Profit-Sharing 401(k)  Retirement Plan as of December 31,
1994 and 1993 and the changes in net assets  available for benefits for the year
ended  December 31,  1994 and the four-month period ended  December 31,  1993 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 purposes 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,  are fairly stated in all material  respects in relation to
the basic financial statements taken as a whole.

Revenue  Service.  However,  the plan  administrator  believes  that the Plan is
currently  designed  and is being  operated in  compliance  with the  applicable
requirements of the Internal  Revenue Code.  Therefore,  the plan  administrator
believes that the Plan was tax-exempt as of December 31, 1994.

Georgia, N.A. was appointed trustee of the NSI Defined Contribution Plans Master
Trust (which  includes the DC Fixed  Income Fund,  DC ZEP Equity Fund and Common
Stock   discussed   in  Note 1).   Certain   officers  of  NSI  were   appointed
administrators of the Plan's assets together with the income derived therefrom.

Prior to  September 1,  1993,  the assets of the Plan were  included  in the NSI
General  Retirement  Trust (GRT).  Under a trust agreement dated March 1,  1978,
certain   officers  of  NSI  were   appointed   trustee  of  the  GRT  and  were
administrators  of the  Plan's  assets  and  Wachovia  Bank of  Georgia  was the
custodian.

3. PLAN DESCRIPTION

The  following  brief  description  of the Plan is  provided  for  informational
purposes only. Participants should refer to the Plan agreement for more complete
information.

The Plan was established as a spin-off from the ZEP Manufacturing Company Profit
Sharing  Retirement  Plan (the "Prior  Plan") to cover all eligible  hourly paid
employees  represented by a collective bargaining unit. The Plan is a voluntary,
defined  contribution plan covering all union employees of the Company, who have
attained  the age of 21,  with at least  six  months  of  service,  as  defined.
Participants  may contribute  between 1% and 10% of before-tax  compensation but
not to  exceed  $8,994  (or  such  larger  amount  as may be  determined  by the
Secretary of Treasury) for any  participant in any calendar year.  Contributions
are  made  by  the  Company  in an  amount  equal  to  the  same  percentage  of
compensation of participants  under this Plan as employer  contributions  to the
Prior Plan bears to the total  compensation  of the eligible  employees  who are
participants under the Prior Plan. The Company contributes 5% of net profits, as
defined.  The  total  of  these  amounts  can be  increased  for any  additional
discretionary  amount  determined  by the Board of Directors of NSI. The maximum
compensation   with  respect  to  any   participant  for  purposes  of  employer
contributions to the Plan is $40,000.

During  December  1993,  the Plan was amended and restated to allow  participant
directed investments effective January 1,  1994. In addition,  the Plan year end
was changed from  August 31 to  December 31.  Thus, the  accompanying  financial
statements are for the year ended December 31, 1994 and the four month period in
the short plan year ended December 31,  1993. The Plan, as amended and restated,
does not permit employer contributions during the short plan year.

Non-vested employer  contributions are forfeited upon withdrawal or termination,
as defined, from the Plan and are allocated to remaining  participants.  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. Participants are always fully vested in their individual contributions.

Although the Company  intends for the Plan to be  permanent,  the Plan  provides
that the Company has the right to discontinue  contributions or to terminate the
Plan at any time. In the event of termination,  each participant shall be vested
with the  balance  of his  account  and his  proportionate  share of any  future
adjustments or forfeitures.
