Item 7.   Identification and Classification of the Subsidiary Which
          Acquired the Security Being Reported on By the Parent Holding
          Company or Control Person.

          Not applicable.

Item 8.   Identification and Classification of Members of the Group

The Cypress Group L.L.C., a Delaware limited liability company ("Cypress
Group"), is the sole general partner of Cypress Associates L.P., a Delaware
limited partnership ("Cypress Associates"); and Cypress Associates is the sole
general partner of Cypress Merchant Banking Partners L.P., a Delaware limited
partnership ("CMBP"), and the sole investment general partner of Cypress
Offshore Partners L.P., a Cayman Islands exempted limited partnership ("COP"),
and therefore each of Cypress Group and Cypress Associates may be deemed to be
the beneficial owner of the securities held by such limited partnerships.
However, each of Cypress Group and Cypress Associates disclaims that it is a
beneficial owner of such securities, except to the extent of its pecuniary
interest in such securities. Because Cypress Group is a general partner of
Cypress Associates and Cypress Associates is a general partner of each of CMBP
and COP and because CMBP and COP acted together in their acquisition and
disposition of the securities held by such limited partnerships, CMBP and COP
may be deemed to be a member of "group" in relation to their respective
investments in WESCO International, Inc. CMBP and COP do not affirm the
existence of a group.
