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

         As an inducement to Parent and Merger Sub to enter into the Merger
Agreement (as defined in Item 4), Parent and Merger Sub entered into a
Stockholder Agreement, dated as of May 1, 2005 (the "Stockholder Agreement"),

the Stockholder Agreement. In addition, the Stockholders delivered an
irrevocable proxy for the purpose of voting the shares covered by the
Stockholder Agreement.

         Item 4.           Purpose of Transaction.
                           ----------------------

         On May 1, 2005, Parent, Merger Sub, and the Company entered into an
Agreement and Plan of Merger (the "Merger Agreement") providing for the merger
(the "Merger") of Merger Sub with and into the Company, which will result in the
Company becoming a wholly-owned subsidiary of Parent. Subject to the terms and
conditions of the Merger Agreement, at the effective time of the Merger, each
share of Class A Common Stock, par value $0.01 per share, of the Company (the
"Class A Common Stock"), Class B Common Stock and Class C Common Stock, par
value $0.01 per share, of the Company (together with the Class A and Class B
Common Stock, the "Common Stock") issued and outstanding immediately prior to
the effective time of the Merger will be converted into the right to receive
$100.00 in cash (other than shares held in the treasury of the Company or owned
by Merger Sub, Parent or any wholly-owned subsidiary of Parent or the Company
and other than shares held by a stockholder who properly demands statutory
appraisal rights).

         In connection with the Merger Agreement, the Stockholders entered into
a Stockholder Agreement with Parent and Merger Sub with respect to (i) 16,471
shares of Class A Common Stock and 6,038,586 shares of Class B Common Stock,
collectively representing all of the Common Stock beneficially owned by the
Stockholders as of the date of the Stockholder Agreement, and (ii) any Common
Stock acquired by such Stockholders after the date of the Stockholder Agreement
(collectively, the "Covered Shares"). Subject to the terms and conditions of the
Stockholder Agreement, each Stockholder has agreed to vote all of the Covered
Shares that such Stockholder is entitled to vote (a) to approve and adopt the
Merger and the Merger Agreement and (b) against (i) any Acquisition Proposal (as
defined in the Merger Agreement), (ii) any extraordinary dividend or
distribution by the Company or any subsidiary, (iii) any change in the capital
structure of the Company or any of its subsidiaries (other than pursuant to the
Merger Agreement) and (iv) any other action that would reasonably be expected
to, in any material respect, prevent, impede, interfere with, delay, postpone,
frustrate the purposes of or attempt to discourage the transactions contemplated
by the Merger Agreement. In addition, each Stockholder agreed that any
agreements among the Stockholders or any of them which could be construed to
limit their respective rights to enter into or perform under the Stockholder
Agreement would be amended to the full extent necessary to assure that entering
into and performing under the Stockholder Agreement would be permitted under
each such agreement without breach of such agreement.

         Each Stockholder irrevocably and unconditionally granted a proxy
appointing Parent as such Stockholder's attorney-in-fact and proxy to vote the
Covered Shares as described above.

         Each Stockholder also agreed not to, without the prior written consent
of Parent or Merger Sub, (i) grant any proxies or enter into any voting trust or
other agreement or arrangement with respect to the voting of any Covered Shares
in a manner inconsistent with the terms of the Stockholder Agreement, (ii)
voluntarily take any action that would or is reasonably likely to (A) make any
representation or warranty contained therein untrue or incorrect in any material
respect or (B) have the effect in any material respect of preventing such
Stockholder from performing its obligations under the Stockholder Agreement or
(iii) voluntarily sell (as defined in the Stockholder Agreement), assign,
transfer, encumber or otherwise dispose of, or enter into any contract, option
or other arrangement or understanding with respect to the direct or indirect
sale, assignment, transfer, encumbrance or other disposition of, any Covered
Shares during the term of the Stockholder Agreement except for transfers (A) to
any person or entity who is subject to the Stockholder Agreement or who becomes
bound thereby as a Stockholder by operation of law or by becoming party to the
Stockholder Agreement or (B) to charitable organizations, provided such shares
constitute, in the aggregate (including all shares so transferred to charitable
organizations by all Stockholders from May 1, 2005), not more than 250,000
shares of the outstanding shares of Common Stock (the "Cap"). Any shares
transferred to any charitable organization on the terms and conditions of clause
(iii)(A) above will not be counted toward the Cap.

         Each Stockholder has agreed to not, directly or indirectly, (i) take
any action to solicit or initiate any Acquisition Proposal or (ii) engage in
negotiations with, or disclose any nonpublic information relating to the Company
or any of its subsidiaries or afford access to the properties, books or records
of the Company or any of its subsidiaries to, any person that may be considering
making, or has made, an Acquisition Proposal or has agreed to endorse an
Acquisition Proposal. Each Stockholder has also agreed to promptly notify Parent
and Merger Sub after receipt of an Acquisition Proposal or any request for
nonpublic information relating to the Company or any of its subsidiaries or for
access to the properties, books or records of the Company or any of its
subsidiaries by any person that may be considering making, or has made, an
Acquisition Proposal and to advise Merger Sub of the status and material details
of any such Acquisition Proposal or request. Each Stockholder has further agreed
not to exercise any rights to demand appraisal of any Covered Shares in
connection with the Merger.

         The Stockholder Agreement will terminate upon the earlier to occur of
the effective time of the Merger and the termination of the Merger Agreement in
accordance with its terms.

         The preceding summary of certain provisions of the Merger Agreement and
the Stockholder Agreement is not intended to be complete and is qualified in its
entirety by reference to the full text of such agreements. A copy of the Merger
Agreement was filed as Exhibit 2.1 to a report on Form 8-K filed by the Company
on May 4, 2005, and is incorporated herein by reference. A copy of the
Stockholder Agreement has been filed herewith as Exhibit 2 to this Schedule 13D
and is incorporated herein by reference.

         Other than as described above, none of the Reporting Persons has any
plans or proposals that relate to or would result in any of the actions
described in Item 4 of Schedule 13D (although the Reporting Persons reserve the
right to develop such plans).

         Item 5.           Interest in Securities of the Issuer.
                           ------------------------------------

         As of the date hereof, neither Parent nor Merger Sub owns any shares of
Common Stock. Parent and Merger Sub may, however, be deemed to have shared
voting power with respect to 16,471 shares of Class A Common Stock and 6,038,586
shares of Class B Common Stock, which are subject to the Stockholder Agreement
described above in Item 4 and which together represent 12.4% of the outstanding
Common Stock. Advisors III, Advisors IV, WP VIII, WP Partners, WP and WP LLC
are, indirectly, the sole stockholders of Parent. As a result, each of Advisors
III, Advisors IV, WP VIII, WP Partners WP and WP LLC may be deemed to
beneficially own any shares of Common Stock that may be deemed to be
beneficially owned by Parent.

         Each of the Reporting Persons disclaims beneficial ownership of any
Common Stock. Neither the filing of this Schedule 13D nor any of its contents
shall be deemed to constitute an admission that any Reporting Person or any of
its affiliates is the beneficial owner of any Common Stock for purposes of
Section 13(d) of the Exchange Act or for any other purpose.

         Except as disclosed in this Schedule 13D, none of the Reporting
Persons, nor (i) to the knowledge of Advisors III and Advisors IV, any of the
persons named on Schedule I hereto, (ii) to the knowledge of the WP Reporting
Persons, any of the persons named on Schedule II hereto and (iii) to the
knowledge of Parent and Merger Sub, any of the persons named on Schedule III
hereto, as of the date hereof, has power to vote or to direct the vote or to
dispose or direct the disposition of any of the shares of Common Stock.

         Except as set forth in this Schedule 13D, none of the Reporting
Persons, nor (i) to the knowledge of Advisors III and Advisors IV, any of the
persons named on Schedule I hereto, (ii) to the knowledge of the WP Reporting
Persons, any of the persons named on Schedule II hereto and (iii) to the
knowledge of Parent and Merger Sub, any of the persons named on Schedule III
hereto, has beneficial ownership of, or has engaged in any transaction during
the past 60 days in, any shares of Common Stock.

         No Reporting Person has the right to receive dividends from and the
proceeds from the sale of any of the Covered Shares that are the subject to the
Stockholder Agreement and reported in this Item 5.

         Percentages set forth in this Schedule 13D were calculated based on
29,525,199 shares of Class A Common Stock and 19,422,379 shares of Class B
Common Stock issued and outstanding as of April 28, 2005, as represented by the
Company in the Merger Agreement.

         Item 6.      Contracts, Arrangements, Understanding or Relationships
                      with Respect to Securities of the Issuer.
                      -------------------------------------------------------

         Except as set forth in response to other Items of this 13D and the
agreements incorporated herein by reference and set forth as exhibits hereto, to
the best knowledge of the Reporting Persons, there are no other contracts,
arrangements, understandings or relationships (legal or otherwise) among the
persons named in Item 2 and between such persons and any person with respect to
any securities of the Company, including but not limited to, transfer or voting
of any of the securities of the Company, joint ventures, loan or option
arrangements, puts or calls, guarantees of profits, division of profits or loss,
or the giving or withholding of proxies, or a pledge or contingency the
occurrence of which would give another person voting power over the securities
of the Company.

             --------------------------------
