The Schedule 13D filed on March 22, 2007 by Pennant Capital Management, LLC, a
Delaware limited liability company ("Pennant Capital") and Alan Fournier, a
United States citizen ("Fournier") (collectively, the "Reporting Persons") with
respect to the shares of Common Stock, par value $0.01 per share (the "Common
Stock"), of PHH Corp., a Maryland corporation (the "Issuer"), as amended by
Amendment Nos. 1, 2 and 3 to the Schedule 13D, is hereby amended as set forth
herein by this Amendment No. 4 to the Schedule 13D.

ITEM 3.       SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

Item 3 of the Schedule 13D is hereby amended and restated as follows:

     Funds for the purchase of the shares of Common Stock reported herein to be
held by Offshore, Onshore, Qualified, Spinnaker, Windward LP and Windward Ltd.
were derived from their respective general working capital and margin account
borrowings made in the ordinary course of business. A total of approximately
$144.5 million was paid to acquire the shares of Common Stock reported herein.

ITEM 4.       PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby amended by the addition of the following:

     On August 10, 2007, Pennant Capital sent a letter to the Issuer's board of
directors welcoming the additional information provided in the Issuer's second
preliminary proxy dated August 6, 2007 (the "Amended Proxy"), which improved
disclosures around each of the five issues Pennant Capital outlined in its
letter dated June 20, 2007. It further stated that the new disclosures in the
Amended Proxy strongly support Pennant Capital's rationale for continued public
ownership and a business separation through a tax-free spin-off. The letter
described how the Amended Proxy reveals that the board likely agreed to sell the
mortgage business for after-tax proceeds of approximately $795 million, which
represents 0.8x tangible book value, or 3.5x 2009 pre-tax earnings as projected
by the Issuer's own management. The letter noted that this price is a
substantial discount to its estimated liquidation value of approximately $997
million. Pennant Capital stated that it was encouraged by the Issuer's internal
financial projections for each business segment, which were consistent with its
own assessment of the Issuer's potential, and it reiterated its belief that the
Issuer will be valued at around $60 per share in two years if the proposed sale
can be prevented as detailed in its previous letters. In conclusion, the letter
demanded that the Issuer make serious efforts into exploring a spin-off and
present shareholders with an analysis that compares continued public ownership
to the proposed sale. A copy of the letter is attached hereto as Exhibit C and
is incorporated herein by reference.

ITEM 5.       INTEREST IN SECURITIES OF THE ISSUER

Paragraphs (a), (b) and (c) of Item 5 of the Schedule 13D are hereby amended and
restated as follows:

     (a-b) Pennant Capital is the manager of each of Offshore, Onshore,
Qualified, Spinnaker, Windward LP and Windward Ltd., and consequently has voting
control and investment discretion over the securities held by each of Offshore,
Onshore, Qualified, Spinnaker, Windward LP and Windward Ltd. As of the date
hereof, the Funds collectively hold 9.4% of the outstanding shares of Common
Stock of the Issuer. Alan Fournier is the managing member of, and thereby
controls, Pennant Capital. The foregoing should not be construed in and of
itself as an admission by any Reporting Person as to beneficial ownership of
shares of Common Stock owned by another Reporting Person. In addition, each of
Pennant Capital and Alan Fournier disclaims beneficial ownership of shares of
Common Stock owned respectively by Offshore, Onshore, Qualified, Spinnaker,
Windward LP and Windward Ltd. The percentages used herein are based upon the
53,680,315 shares of Common Stock reported to be outstanding as of July 16, 2007
by the Issuer in its Quarterly Report on Form 10-Q for the period ended June 30,
2007, filed with the Securities and Exchange Commission on August 8, 2007.
