Item 3.  Source and Amount of Funds or Other Consideration.

     Holdings, WCAS IX and WCAS IX Associates may be deemed to have acquired

Agreement, dated October 17, 2004 (the "Rollover Agreement"), between Holdings,
the TCEP Investors and the SEM Persons. However, such reporting persons
expressly disclaim beneficial ownership of the shares of Common Stock covered by
the Rollover Agreement.

     Subject to the terms of the Rollover Agreement, each TCEP Investor and each
SEM Investor has agreed to (i) contribute certain of their shares of Common
Stock to Holdings prior to the consummation of the Merger (as defined in Item 4
below) and in return receive equity interests in Holdings, (ii) enter into
certain agreements with Holdings, WCAS IX and other equity investors selected by
Holdings with respect to such contribution and (iii) not to transfer any such
shares of Common Stock prior to consummation of the Merger without


                                                           (Page 21 of 27 Pages)

the consent of Holdings. Any contributed shares will be cancelled in the Merger.
In addition, pursuant to such agreement, each SEM Person will execute various
restricted stock award and employment agreements as well as receive other cash
incentives in connection with their continuing employment by the surviving
corporation following consummation of the Merger.

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

     To the extent any WCAS Person who is a reporting person directly
beneficially owns any shares of Common Stock (as set forth in Item 5 below),
such shares were purchased by such reporting person using such reporting
person's personal funds or received pursuant to distributions made to such
reporting person by investment partnerships affiliated with WCAS IX. To the
extent any TCEP Investor directly beneficially owns any shares of Common Stock
(as set forth in Item 5 below), such shares were purchased by each such
reporting person using such reporting person's personal funds. To the extent any
SEM Person directly beneficially owns any shares of Common Stock (as set forth
in Item 5 below), such shares were purchased, directly or indirectly, by such
reporting person using such reporting person's personal funds or pursuant to the
cashless exercise of options.

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, at the effective time of the Merger, 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 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 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, WCAS IX 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 (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 $480.0 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 breach.

     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.
