     This Amendment No. 1 amends and supplements the Statement on Schedule 13D
filed with the Securities and Exchange Commission on April 9, 2002 (the
"Statement"). Capitalized terms used and not defined herein shall have the
meanings assigned to such terms in the Statement.

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

     Item 3 of the Statement is hereby amended and supplemented by adding the
following information thereto:

     On April 30, 2002, the parties to the Stock Purchase Agreement consummated
the Stock Purchase. The Majority Shareholder Exchange Ratio was determined to be
1.2973. Immediately prior to the Stock Purchase, Majority Shareholder redeemed
1,825,127 shares of Trendwest Common Stock held by Majority Shareholder in
exchange for the MountainStar development project and certain assets related
thereto. The TII Price was equal to approximately $76 million in net assets less
approximately $32 million of debt related to MountainStar assumed by the
Majority Shareholder as a consequence of the MountainStar Redemption.
Accordingly, on April 30, 2002, Merger Sub acquired a total of 32,800,234 shares
of Trendwest Common Stock pursuant to the Stock Purchase and Cendant issued
42,551,860 shares of Parent Common Stock pursuant to such Stock Purchase, in
accordance with the terms of the Stock Purchase Agreement and an exchange ratio
of 1.2973 shares of Parent Common Stock for each share of Trendwest Common
Stock. In addition, on May 1, 2002, Merger Sub purchased an additional 100,000
shares of Trendwest Common Stock at a price of $24.00 per share pursuant to an
exercise of the Option for an aggregate exercise price of $2.4 million in cash.
The exercise price was paid by working capital funds of Cendant.

Item 4.  Purpose of Transaction.

     Item 4 of the Statement is hereby amended and supplemented by adding the
following information thereto:

     On April 30, 2002, the parties to the Stock Purchase Agreement consummated
the Stock Purchase. On such date, Merger Sub acquired 32,800,234 shares of
Trendwest Common Stock in stock purchases contemplated by the Stock Purchase
Agreement.

     On May 1, 2002, Merger Sub purchased an additional 100,000 shares of
Trendwest Common Stock pursuant to an exercise of the Option.

     Immediately following the Stock Purchase, William F. Peare, Jeffrey P.
Sites, Jerol E. Andres, Douglas P. Kintzinger and Roderick C. Wendt resigned as
members of Trendwest's board of directors. Pursuant to the bylaws of Trendwest,
Trendwest's board of directors elected James E. Buckman, Stephen P. Holmes,
Samuel L. Katz, and Kevin M. Sheehan, each a designee


                                       Page 5 of 7



of Cendant, to fill the vacancies on the board of directors, each such director
to hold office until the next annual meeting of shareholders.

Item 5.  Interest in Securities of the Issuer.

     Item 5 of the Statement is hereby amended and supplemented by adding the
following information thereto:

     On April 30, 2002, Merger Sub acquired 32,800,234 shares of Trendwest
Common Stock in stock purchases contemplated by the Stock Purchase Agreement. On
May 1, 2002, Merger Sub purchased an additional 100,000 shares of Trendwest
Common Stock pursuant to an exercise of the Option. By virtue of such stock
acquisitions, Cendant and Merger Sub may each be deemed to beneficially own
32,900,234 shares of Trendwest Common Stock, which is the equivalent of 90.4% of
a total of 36,394,496 shares of Trendwest Common Stock outstanding as of May 1,
2002. In addition, Cendant and Merger Sub may each be deemed to beneficially own
an additional 36,785 shares of Trendwest Common Stock by virtue of Merger Sub's
right under the Option to purchase up to that number of shares of Trendwest
Common Stock as may be necessary to ensure that Merger Sub will beneficially own
not less than 90.5% of the shares of Trendwest Common Stock on the date of any
exercise. Accordingly, based on the total number of shares of Trendwest Common
Stock outstanding as of May 1, 2002, Cendant and Merger Sub may each be deemed
to beneficially own 32,937,109 shares of Trendwest Common Stock, which is the
equivalent of 90.5% of the total number of shares of Trendwest Common Stock
outstanding as of such date.
