Item 4.  PURPOSE OF TRANSACTION.

         (a through j) On October 17, 2004, Holdings, EGL Acquisition Corp., a
Delaware corporation ("Acquisition"), and the Issuer entered into an Agreement
and Plan of Merger, a copy of which is attached hereto as Exhibit C (the "Merger
Agreement"), pursuant to which Acquisition, a wholly owned subsidiary of
Holdings, will be merged with and into the Issuer, with the Issuer continuing as
the surviving corporation (the "Merger"). Following the consummation of the
Merger, the Issuer will be a wholly owned subsidiary of Holdings. Under the
terms of the Merger Agreement, each existing share of Common Stock, other than
shares held by WCAS IX or its affiliates, treasury shares and dissenting shares,
will be converted into the right to receive $18.00 in cash (the "Merger
Consideration"). In addition, all outstanding options for Common Stock will be
converted into the right to receive the Merger Consideration less the exercise
price of such options. The Merger remains subject to the satisfaction or waiver
of the conditions set forth in the Merger Agreement, including obtaining
approval of the existing shareholders of the Issuer.

          Pursuant to the Merger Agreement, the board of directors of
Acquisition at the effective time of the Merger will become the board of
directors of the Issuer. In addition, the certificate of incorporation of the
Issuer will be amended and restated at the effective time of the Merger to
conform to an exhibit attached to the Merger Agreement (the bylaws of the Issuer
will not change). If the Merger is consummated, the Common Stock will be
delisted from the New York Stock Exchange and will be deregistered under Section
12(g)(4) of the Exchange Act.

         The foregoing description of the Merger Agreement is qualified in its
entirety by reference to such agreement, a copy of which is attached hereto as
Exhibit C, and is incorporated herein by reference.

         In addition to the transactions contemplated by the Initial Rollover
Agreement and Subsequent Rollover Agreement, the Merger is expected to be
financed by equity investments in Holdings to be made by certain of the
reporting persons and related investors, certain loan arrangements to be entered
into by Holdings and the Issuer with JP Morgan Chase Bank, Wachovia Bank,
National Association and Merrill Lynch Capital Corporation (collectively, the
"Lenders"), and a loan to be made to Holdings by WCAS Capital Partners IV, L.P.,
a Delaware limited partnership ("WCAS CP IV") and an affiliate of WCAS IX. The
specific investments and loans are discussed below.

         Pursuant to an Equity Commitment Letter, dated as of October 17, 2004
(the "WCAS Equity Commitment


                                                           (Page 27 of 33 Pages)

Letter"), by and between Holdings and WCAS IX, a copy of which is attached
hereto as Exhibit D, WCAS IX and certain related investors, including the WCAS
Persons, will provide up to $567.2 million in cash to Holdings in return for
equity interests in Holdings. The cash proceeds of such investment will be
contributed by Holdings to Acquisition to finance a portion of the consideration
for the Merger. Also, Holdings has an understanding with the WCAS Persons who
are reporting persons that such WCAS Persons will contribute certain of their
shares of Common Stock to Holdings prior to the consummation of the Merger and
in return receive equity interests in Holdings. Any contributed shares will be
cancelled in the Merger. In addition, pursuant to the WCAS Equity Commitment
Letter, a designee of WCAS IX, as agent for various entities, will receive a
financing fee equal to $24.6 million and WCAS IX and its affiliates will be
reimbursed for all of their out-of-pocket fees and expenses.

         Pursuant to an Equity Commitment Letter, dated as of October 17, 2004
(the "TCEP Equity Commitment Letter"), by and between Holdings and Thoma Cressey
Fund VII, L.P., a Delaware limited partnership ("TCEP VII"), a copy of which is
attached hereto as Exhibit E, TCEP VII and certain related investors, each of
which are affiliates of one or more of the TCEP Investors, will provide up to
$50.0 million in cash to Holdings in return for equity interests in Holdings.
The cash proceeds of such investment will be contributed by Holdings to
Acquisition to finance a portion of the consideration for the Merger. In
addition, WCAS IX and TCEP VII have an understanding that TCEP VII, or its
designee will be entitled to receive a portion of the financing fee payable
pursuant to the WCAS Equity Commitment Letter and TCEP VII and its affiliates
will be reimbursed for all of their out-of-pocket fees and expenses.

         Pursuant to a Senior Secured Credit Facilities and Senior Subordinated
Bridge Facility Commitment Letter, dated October 17, 2004, as amended and
restated as of December 20, 2004 (the "Debt Commitment Letter"), by and among
Holdings and the Lenders, a copy of which is attached hereto as Exhibit F, the
Lenders have agreed to provide (i) a $580.0 million senior secured term loan
facility and (ii) a $300.0 million revolving credit facility (collectively, the
"Bank Facility"). The Debt Commitment Letter contemplates that the Issuer and/or
Holdings will issue an aggregate $660.0 million unsecured senior subordinated
notes (the "Notes") pursuant to a Rule 144A offering. In the event that the
Notes are not issued at the time the Merger is consummated, the Lenders have
agreed to provide a bridge loan facility in the amount of up $660.0 million
under a senior unsecured credit facility (the "Bridge Facility"). The Bank
Facility and the Bridge Facility are expected to contain customary terms and
conditions, including, without limitation, with respect to fees, indemnification
and events of default. A portion of the proceeds of these loan arrangements will
be used to finance a portion of the consideration for the Merger.

         Pursuant to a Commitment Letter, dated as of October 17, 2004 (the "CP
IV Commitment Letter"), by and between Holdings and WCAS CP IV, a copy of which
is attached hereto as Exhibit G, WCAS CP IV will provide up to $150.0 million in
cash to Holdings in return for a senior subordinated note. The cash proceeds of
such loan will be contributed by Holdings to Acquisition to finance a portion of
the consideration for the Merger. Pursuant to the CP IV Commitment Letter, WCAS
CP IV and its affiliates will be reimbursed for all of their out-of-pocket fees
and expenses.

         In addition, in connection with the Merger, WCAS IX, Holdings and the
Issuer entered into a Contingency Letter Agreement, dated October 17, 2004 (the
"Contingency Letter"), a copy of which is attached hereto as Exhibit H, pursuant
to which WCAS IX agreed that, in the event the Issuer terminates the Merger
Agreement and such termination arises from a knowing and willful breach of the
Merger Agreement by Acquisition and/or Holdings, it will make an equity
contribution to Holdings of up to $10.0 million to satisfy any liabilities of
Holdings or Acquisition resulting from such knowing or willful.

         The foregoing descriptions of the WCAS Equity Commitment Letter, the
TCEP Equity Commitment Letter, the Debt Commitment Letter, the CP IV Commitment
Letter and the Contingency Letter are qualified in their entirety by reference
to such agreements, copies of which are attached as Exhibits D, E, F, G and H,
respectively, and are incorporated herein by reference.
