(collectively, the “Padua Investors”). The Padua Investors are the direct or indirect owners of Padua. The Padua Investors severally acquired an aggregate of 12,500,000 shares of common stock of Puget Energy, Inc., a Washington corporation (“Puget”), on December 3, 2007 from Puget pursuant to a Stock Purchase Agreement, dated October 25, 2007 (the “Stock Purchase Agreement”), as described in Items 4 and 5 of this Schedule 13D. Concurrent with the execution of the Stock Purchase Agreement, Padua, Puget Intermediate Holdings Inc. (f/k/a Padua Intermediate Holdings Inc.), a Washington corporation and wholly owned subsidiary of Padua (“Padua Intermediate”), Puget Merger Sub Inc. (f/k/a Padua Merger Sub Inc.), a Washington corporation and wholly owned subsidiary of Padua Intermediate (“Merger Sub”), and Puget entered into an Agreement and Plan of Merger, dated as of October 25, 2007 (the “Merger Agreement”), pursuant to which Padua will acquire all of the outstanding common stock of Puget as described in Item 4 of this Schedule 13D. The Stock Purchase Agreement and the Merger Agreement are separate transactions that include, among other things, different conditions to each party’s obligation to close the transaction and different termination rights. Padua expressly disclaims beneficial ownership of any of the shares of common stock in Puget that may be beneficially owned by the Padua Investors and expressly declares that the filing of this Schedule 13D shall not be construed as an admission that Padua is, for purposes of Section 13(d) and (e) of the Exchange Act, the beneficial owner of the shares of common stock of Puget that may be beneficially owned by the Padua Investors.
** Based on the representation of Puget set forth in the Merger Agreement that 117,176,878 shares of common stock were outstanding as of October 23, 2007, and adding to that number the 12,500,000 shares of common stock issued in connection with the Stock Purchase Agreement (the “Declared Shares Outstanding”). Under Section 13(d)(3) of the Exchange Act and based on the number of Declared Shares Outstanding, Padua may be deemed to have shared power to vote and shared power to dispose of approximately 9.6% of the outstanding common stock of Puget.

Item 4. Purpose of the Transaction
Padua, Puget Intermediate Holdings Inc. (f/k/a Padua Intermediate Holdings Inc.), a Washington corporation and wholly owned subsidiary of Padua (“Padua Intermediate”), Puget Merger Sub Inc. (f/k/a Padua Merger Sub Inc.), a Washington corporation and wholly owned subsidiary of Padua Intermediate (“Merger Sub”), and Puget entered into an Agreement and Plan of Merger, dated as of October 25, 2007 (the “Merger Agreement”), a copy of which was filed as Exhibit 2.1 to a Form 8-K filed by Puget on October 29, 2007, File No. 01-16305, and is incorporated herein by reference. The description of the Merger Agreement set forth herein is qualified in its entirety by reference to the copy filed as Exhibit 2.1 to such Form 8-K.
Pursuant to the Merger Agreement, Merger Sub will merge with and into Puget (the “Merger”), with Puget continuing as the surviving corporation and as an indirect wholly owned subsidiary of Padua. At the effective time of the Merger each then outstanding share of Common Stock (excluding any shares of Common Stock owned by Padua and its subsidiaries and any shares of Common Stock in respect of which dissenter’s rights are perfected) will be converted automatically into the right to receive $30.00 in cash, without interest.
Concurrent with the execution of the Merger Agreement, Puget and the Padua Investors entered into a Stock Purchase Agreement, dated as of October 25, 2007 (the “Stock Purchase Agreement”), a copy of which was filed as Exhibit 10.1 to a Form 8-K filed by Puget on October 29, 2007, File No. 01-16305, and is incorporated herein by reference. The description of the Stock Purchase Agreement set forth herein is qualified in its entirety by reference to the copy filed as Exhibit 10.1 to such Form 8-K. The Stock Purchase Agreement and the Merger Agreement are separate transactions that include, among other things, different conditions to each party’s obligation to close the transaction and different termination rights. Under the terms of the Stock Purchase Agreement, the Padua Investors severally purchased an aggregate of 12,500,000 shares of Common Stock (the “Purchased Shares”) at a purchase price of $23.67 per share on December 3, 2007.

15


 

The Stock Purchase Agreement contains customary representations, warranties and covenants of Puget and the Padua Investors including, among others, covenants imposing confidentiality and standstill obligations on the Padua Investors, covenants imposing restrictions on the Padua Investors’ rights to transfer and vote the Purchased Shares during the pendency of the Merger Agreement, and indemnification obligations on the part of each party with respect to certain liabilities of the other parties incurred in connection with the transaction; provided that Puget will not be required to make any payments under this indemnification obligation unless and until the Merger Agreement is terminated. In addition, Puget has granted the Padua Investors registration rights with respect to the Purchased Shares following any termination of the Merger Agreement.
In addition, in connection with the transactions contemplated by the Merger Agreement, Padua, Padua Intermediate, MIP Padua Holdings, GP (the beneficial owners of MIP Padua Holdings, GP are Macquarie Infrastructure Partners A, L.P., Macquarie Infrastructure Partners International, L.P. and Macquarie Infrastructure Partners Canada, L.P.), Macquarie Specialised Asset Management Limited as responsible entity for Macquarie FSS Infrastructure Trust, Padua MG Holdings Inc., CPP Investment Board (USRE II) Inc., Padua Investment Trust, PIP2PX (Pad) Ltd. and PIP2GV (Pad) Ltd. (the “Padua Members”) entered into a Commitment Letter, dated as of October 25, 2007 (the “Commitment Letter”). Pursuant to the Commitment Letter, each Padua Member shall contribute, or cause to be contributed, the Purchased Shares to Padua in satisfaction of a portion of its equity contribution amount once Padua gives written notice to the Padua Members that all conditions precedent to the obligations of Puget and Padua to consummate the Merger have been satisfied or waived by the party entitled to waive such conditions as provided in the Commitment Letter. Upon such satisfaction or waiver, the Commitment Letter also requires the Padua Members to provide Padua with funds sufficient, when aggregated with the Purchased Shares, to consummate the Merger. Pursuant to the Commitment Letter and the Merger Agreement, certain of these funds were deposited into an escrow account contemporaneously with the execution of the Merger Agreement to secure Pauda’s obligations to pay a Business Interruption Fee to Puget if the Merger Agreement were to be terminated under certain circumstances. Other amounts were deposited into an escrow account for the payment of certain transaction expenses of Paudua accrued in connection with the consummation of the transactions contemplated by the Merger Agreement.
To the knowledge of Padua, the Padua Investors intend to evaluate periodically the advisability of continuing to hold or selling the Purchased Shares or acquiring additional shares of Common Stock based upon the trading price of the Common Stock, the liquidity requirements of the Padua Investors and the progress of the Merger. In connection with these evaluations, the Padua Investors may study or prepare plans or proposals to facilitate dispositions of the Purchased Shares and may change their current intentions with respect to the Purchased Shares. Notwithstanding the foregoing, except in limited circumstances set forth in the Stock Purchase Agreement, the Padua Investors are prohibited from selling the Purchased Shares until the Merger Agreement is terminated. Any Padua Investor that individually or as part of a group owns 2% or more of the outstanding shares of Common Stock is prohibited from acquiring additional shares of Common Stock until 18 months after the termination of the Merger Agreement.
The Merger Agreement is expected to result in Padua owning all of the shares of Common Stock, par value $0.01 per share of Puget as the surviving corporation in the Merger, accompanied by a delisting and deregistration of such shares, a change in Puget’s board of directors and a change in Puget’s capitalization as a result of the indebtedness intended to be incurred in connection with

the Merger. Puget’s charter and bylaws will also be amended and restated upon consummation of the Merger.

Other than as described above, neither the Reporting Persons, nor, to the knowledge of the Reporting Persons, any person listed on Schedules I-IX attached hereto have any current plans or proposals that relate to or would result in any of the actions set forth in items (a) through (j) of Item 4 of the instructions to Schedule 13D, although the Reporting Persons reserve the right to develop such plans or proposals.
