Item 5 (Interest in Securities of the Issuer) and Item 6 (Contracts,
Arrangements, Understanding or Relationships with respect to Securities of the
Issuer) of the Schedule 13D are hereby amended and supplemented by adding the
following:
"Pursuant to an agreement dated January 16, 2001, by and among the
Purchaser, Mr. Lederer and the Rochester Area Community Foundation ("RACF"), Mr.
Lederer has transferred (the "Transfer") 30,000 Shares (the "Transferred
Shares") to RACF, and RACF has agreed to assume all of Mr. Lederer's rights and
obligations under the Voting and Option Agreement with respect to the
Transferred Shares. The staff (the "Staff") of the SEC has advised Parent and
the Purchaser that, as a result of the Voting and Option Agreement, Parent and
the Purchaser may be deemed to have formed a group with Messrs. Kostusiak and
Lederer, the other parties to the Voting and Option Agreement, within the
meaning of Section 13(d) of the Exchange Act. Under the Staff's position and
Rule 13d-5(b)(1) under the Exchange Act, each member of such a group would be
deemed to beneficially own all Shares owned by each other member of such group.
Thus, under the Staff's position and as a result of the Transfer and the
assumption by RACF of the rights and obligations of Mr. Lederer under the Voting
and Option Agreement, Parent and the Purchaser would be deemed to also
beneficially own the Transferred Shares and any other Shares owned by RACF.
Parent and the Purchaser have no basis for knowing whether RACF beneficially
owns any Shares other than the Transferred Shares. While Parent and the
Purchaser do not agree with the Staff's position, Parent and the Purchaser are
hereby reporting in accordance with the Staff's position that, as a result of
the Voting and Option Agreement, such a group may have been deemed to have been
formed for purposes of Section 13(d) of the Exchange Act and may include RACF.
Parent and the Purchaser, however, disclaim beneficial ownership of any Shares
(other than the Transferred Shares) beneficially owned by RACF pursuant to Rule
13(d)(4) of the Exchange Act."
