ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS

(c)  Exhibits

Exhibit No.       Description of Exhibit

99.1     Press Release dated May 13, 2003


ITEM 9. REGULATION FD DISCLOSURE (INFORMATION PROVIDED UNDER ITEM 12. RESULTS OF
        OPERATIONS AND FINANCIAL CONDITION)

Operations and Financial Information Furnished

On May 13, 2003, the Company issued a press release announcing its fiscal second
quarter 2003 financial and operating results. This press release is furnished as
Exhibit 99.1, and incorporated herein by reference.

In addition, the Company announced in a press release issued on May 2, 2003 that
a webcast of a second quarter conference call would be held on May 13, 2003.

The press release  furnished  herewith  will be posted to the Company's  website
located  at  http://www.escotechnologies.com  and  can  be  viewed  through  the
Investor Relations page of the website under the tab "Press Releases",  although
the Company reserves the right to discontinue that availability at any time.

Non-GAAP Financial Measures

The press release furnished  herewith contains  financial measures and financial
terms not calculated in accordance with generally accepted accounting principles
in the United  States of America  ("GAAP")  in order to  provide  investors  and
management  with an  alternative  method for assessing  the Company's  operating
results in a manner that is focused on the performance of the Company's  ongoing
operations.  The  Company  has  provided  definitions  below  for  the  non-GAAP
financial  measures utilized in the press release,  together with an explanation
of why management  uses these measures,  and why management  believes that these
non-GAAP financial measures are useful to investors.  The press release uses the
non-GAAP  financial  measures of "Net earnings  excluding the after-tax  charges
relating to the MSA and MTA," "EBIT from continuing operations," "EBIT excluding
the  after-tax  charges  relating  to the MSA and MTA,"  "Free  cash  flow," and
"EBITDA from continuing operations."

The Company defines "Net earnings  excluding the after-tax  charges  relating to
the MSA and MTA" as net earnings  excluding the special  items  described in the
press release. These special items comprise a one-time charge resulting from the
termination of a Manufacturing  and Supply Agreement (MSA) with Whatman HemaSure
Inc., and costs resulting from the Management  Transition  Agreement between the
Company  and its former  Chairman  (MTA).  The  Company's  management  uses this
information  in  evaluating  the  results of the  continuing  operations  of the
Company  and  believes  that this  information  provides  investors  with better
insight into the period over period financial performance of the Company.

The  Company  defines  "EBIT from  continuing  operations"  as  earnings  before
interest and taxes.  The Company's  management  evaluates the performance of its
operating  segments based on EBIT from  continuing  operations and believes that
EBIT from  continuing  operations  is useful to  investors  to  demonstrate  the
operational  profitability  of the  Company's  business  segments  by  excluding
interest and taxes, which are generally  accounted for across the entire Company
on a  consolidated  basis.  EBIT from  continuing  operations is also one of the
measures used by  management  in  determining  resource  allocations  within the
Company and incentive compensation.

"EBIT excluding the after-tax  charges relating to the MSA and MTA": The Company
calculates  this non-GAAP  financial  measure as EBIT of the Company's  business
operations  for the  respective  period,  excluding the special items  described
above  in the  discussion  of "Net  earnings  excluding  the  after-tax  charges
relating to the MSA and MTA." The Company's  management uses this information in
evaluating the results of the continuing  operations of the Company and believes
that this  information  provides  investors  with better insight into the period
over period financial performance of the Company.

The  Company  defines  "Free  cash  flow" as "Net  cash  provided  by  operating
activities" less "Capital expenditures".  The Company's management believes that
free cash flow is useful to investors and management as a supplemental financial
measurement in the  evaluation of the Company's  business and believes that free
cash flow may  provide  additional  information  with  respect to the  Company's
ability  to meet its future  debt  service,  capital  expenditures  and  working
capital  requirements.  Free cash flow can also be reinvested in the Company for
future growth.

The Company  defines  "EBITDA from  continuing  operations"  as earnings  before
interest,  taxes,  depreciation and amortization.  The Company's management uses
EBITDA  as a  supplemental  financial  measurement  in  the  evaluation  of  the
Company's business and believes that EBITDA may provide  additional  information
with respect to the Company's  ability to meet its future debt service,  capital
expenditures and working capital requirements.

The presentation of net earnings excluding the after-tax charges relating to the
MSA and MTA,  EBIT from  continuing  operations,  EBIT  excluding  the after-tax
charges  relating to the MSA and MTA, free cash flow, and EBITDA from continuing
operations,  is intended to supplement investors' understanding of the Company's
operating  performance.  The Company's  non-GAAP  financial  measures may not be
comparable  to  other  companies'  non-GAAP  financial   performance   measures.
Furthermore,  these  measures  are not  intended to replace net  earnings,  cash
flows,  financial  position,  or comprehensive  income (loss),  as determined in
accordance with GAAP.
