                 ONLINE POWER SUPPLY CLARIFIES VOTING PROCEDURES
                      FOR ANNUAL MEETING ON AUGUST 14, 2002

     We want to re-double our efforts to make the voting instructions as
distributed for the street name or brokerage account shareholder mailing as
clear as possible. It isn't apparent that you have a clear choice to vote
"against" an individual director nominee. OPS has taken steps to ensure that all
shareholders' right to vote against one or more nominees is recognized in the
voting process. Please read the following carefully.

     The beneficial owners are receiving from their brokers an instruction
ballot prepared by ADP Proxy Services, Inc. which has boxes "For All Nominees,"
"Withhold All Nominees," and "Withhold Authority To Vote For Any Individual
Nominee- Write Number(s) of Nominees Below." The numbers assigned to each
director nominee are listed on the front of ADP's instruction ballot. ADP's
instructions should follow our procedure for voting for directors precisely.
ADP's instructions do not have the same procedures for voting for directors as
OPS' proxy card.

     WE WANT TO ELIMINATE THE CONFUSION CAUSED BY ADP'S METHOD IN LAYING OUT OUR
PROXY FORMAT. YOUR VOTES "WITHHOLD" WILL BE COUNTED AS VOTES "AGAINST."

     OPS and its transfer agent will count instructions on ADP's box "Withhold
All Nominees" as a VOTE AGAINST ALL NOMINEES.

     OPS and its transfer agent will count instructions on ADP's box "Withhold
Authority To Vote For Any Individual Nominee," followed by a number or numbers
indicating withhold authority for one or more of the directors (as numbered on
the instructions), as a vote AGAINST the individual director or directors
indicated.

     We want to encourage everyone to vote as soon as possible.
