Explanatory Note

         Espey Mfg. & Electronics Corp., a New York corporation (the "Company")
is filing this Post-Effective Amendment No. 1 to Registration Statement on Form
S-8 to register certain securities previously registered by the Company pursuant
to its Registration Statement on Form S-8 filed with the Securities and Exchange
Commission on October 11, 2005 (Registration No. 333-128922) (the "Initial
Registration Statement"). The Initial Registration Statement registered 129,700
shares of the Company's common stock (the "Common Stock") for issuance, offer or
sale pursuant to the Company's 2000 Stock Option Plan (the "2000 Plan").

         On November 30, 2007, stockholder approval was obtained by the
Company's 2007 Stock Option and Restricted Stock Plan (the "2007 Plan"), which
replaced the 2000 Plan. No further grants of options will be made under the 2000
Plan. The 2000 Plan has 77,000 shares of Common Stock that would otherwise be
available for grant under such plan (the "Carryover Shares") now available for
issuance, offer and sale under the 2007 Plan.

         The Carryover Shares are hereby deregistered. The Initial Registration
Statement otherwise continues in effect as to the balance of the shares of
Common Stock remaining available for issuance, offer or sale pursuant thereto
upon and the following the exercise of options previously granted under the 2000
Plan.
