Capitalized terms used herein without definition have the meanings specified therefor in that certain Amended and Restated Warehousing Credit and Security Agreement dated as of October 15, 2009, among the Borrowers, the Credit Agent, and the Lenders (the “Loan Agreement”).

R E C I T A L S

The Borrowers, the Credit Agent, and the Lenders desire to amend the Loan Agreement on the terms and conditions set forth herein.

GPF has no Warehousing Advances outstanding under the Loan Agreement, and does not anticipate any new Warehousing Advances being required to be made to it pursuant to the Transition Services Agreement (as defined in the Loan Agreement).

NOW, THEREFORE, in consideration of the agreements of the parties set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.             Amendment. Effective as of the Effective Date (as hereafter defined), the Loan Agreement is amended as follows:

(a)         Clause (a) of Section 1.2 of the Loan Agreement is hereby amended by replacing the date “November 30, 2009” where it appears therein with the date “November 29, 2010.”

(b)         Section 8.8 is hereby deleted in its entirety and replaced with the following:

“8.8      Minimum Tangible Net Worth

Permit W&D’s Adjusted Tangible Net Worth at any time to be (i) less than $75,000,000, to be tested on the last day of each Fiscal Quarter occurring, or (ii) otherwise not in compliance with applicable requirements of HUD, Investors (including Freddie Mac) or Fannie Mae.”

(c)          Section 13.1 is hereby amended by deleting the following definitions in their entirety, and replacing them with the following:

“Applicable Margin” means (a) for LIBOR Loans, 2.75%, and (b) for Base Rate Loans, 2.75%.

“Required Lenders” means, as of any particular date (a) if no Warehousing Advances are outstanding, Lenders whose Warehousing Commitment Amounts aggregate at least 51% of the Warehousing Commitment Amounts of all Lenders who are not Delinquent Lenders, or (b) if any Warehousing Advances are outstanding, Lenders holding at least 51% of the aggregate unpaid principal amount of all then outstanding Warehousing Advances of Lenders who are not Delinquent Lenders; provided, however, that at any time that the Credit Agent holds not less than the lesser of (a) a Commitment Percentage equal to or greater than 33-1/3%, or (b) a Warehousing Commitment Amount of not less than $50,000,000, the term “Required Lenders” shall include the Credit Agent. No Lender which is a Delinquent Lender shall be considered a “Lender” for the purposes of determining the “Required Lenders.”

(d)         Exhibit C to the Loan Agreement is hereby deleted in its entirety and replaced with the form of Exhibit C annexed hereto.

(e)          GPF is hereby removed as a Borrower from the Loan Agreement for all purposes, and all applicable corresponding changes reflecting the deletion of GPF are deemed made.

2.              Accordion Option.

(a)         Capitalized Terms used in this Section 2 which are not defined in the Loan Agreement or defined elsewhere in this Amendment have the meanings specified therefor in Section 2(g), below.

(b)         At the request of the Borrowers as provided herein, the Warehousing Commitment Amount may be increased by an amount of up to $50,000,000 (bringing the total Warehousing Commitment Amount to a maximum of $150,000,000), upon the Credit Agent’s determination that the Accordion Conditions have been fully satisfied. In such event, subject to all applicable provisions of the Accordion Loan Documents, the Lenders and the Accordion Lenders shall thereafter make Warehousing Advances to the Borrowers based upon the increased Warehousing Commitment Amount and their respective Commitment Percentages. The obligations of the Lenders and the Accordion Lenders shall be several and not joint.

(c)          With respect to any increase to the Warehousing Commitment Amount requested by the Borrowers, the Borrowers hereby acknowledge and agree as follows:

(i)            The request for such increase (the “Accordion Notice”) must (A) be in writing, and (B) specify the amount of the requested increase to the Warehousing Commitment Amount, which requested increase (x) may not exceed $50,000,000, and (y) must be at least $15,000,000.

(ii)           Credit Agent will manage all aspects of the proposed syndication of the requested increase to the Warehousing Commitment Amount, including, without limitation, the final allocations of the increased Warehousing Commitment Amount among the Lenders and the Accordion Lenders, the respective Commitment Percentages, and the allocation of interest and fees.

(iii)          After the Borrowers’ request to increase the Warehousing Commitment Amount, the Borrowers shall cooperate with the Credit Agent in connection with the efforts of the Credit Agent to achieve a Successful Accordion Syndication, to include, among other things: (a) permitting and facilitating direct contact during the syndication between each Borrower’s senior officers, representatives and advisors, on the one hand, and prospective lenders, on the other hand, at such times and places as the Credit Agent may reasonably request; (b) providing to the Credit Agent and prospective Accordion Lenders all financial and other information as they may reasonably request, including, without limitation, projections and forecasts; and (c) assistance in the preparation of a confidential information memorandum and other marketing materials to be used in connection with the proposed syndication of the requested increased Warehousing Commitment Amount.

(d)         The Borrowers may give only one Accordion Notice.

(e)          The Credit Agent (i) is only agreeing to use reasonable and customary efforts to achieve a Successful Accordion Syndication, (ii) is not, nor is any Lender, agreeing or committing to increase the amount of its Warehousing Commitment, and (iii) is not guarantying that any efforts to achieve a Successful Accordion Syndication will succeed.

(f)          Credit Agent may elect, in its discretion, to abandon its efforts to achieve Successful Accordion Syndication if it determines that such efforts are not likely to succeed. In such event, (i) the Credit Agent and Lenders shall have no obligation to increase the existing Warehousing Commitment Amount, (ii) the Credit Agent and the Lenders shall have no liability to the Borrowers or any other Person with respect to the efforts undertaken by the Credit Agent in connection therewith or the failure to achieve a Successful Accordion Syndication, and (iii) the Borrowers promptly shall reimburse the Credit Agent for all costs and expenses incurred by the Credit Agent in its syndication efforts.

(g)          As used herein, the following terms have the following meanings:

“Accordion Conditions” means the satisfaction of all of the following conditions precedent, each as determined by the Credit Agent:

(a)           A Successful Accordion Syndication shall have been achieved (including, without limitation, the execution and delivery by all applicable parties

(b)         As of the date of the Accordion Notice and as of the effective date of the increase to the Warehousing Commitment Amount, no Default or Event of Default shall have then occurred and be continuing;

(c)          The Borrowers shall have paid all fees required by this Agreement and in any other agreement between the Borrowers and the Credit Agent; and

(d)         The Borrowers shall have paid all fees, costs, and expenses (including, without limitation, all attorneys’ reasonable fees) incurred by the Credit Agent, the Lenders, and the Accordion Lenders in connection with the Successful Accordion Syndication and the preparation, negotiation, execution, and delivery of the Accordion Loan Documents.

“Commitment Percentage” means, in the event of a Successful Accordion Syndication, the respective Warehousing Commitments of the Lenders and each Accordion Lender, expressed as a percentage of the total increased Warehousing Commitment Amount.

“Accordion Lender” means each lender, acceptable to the Credit Agent, in its discretion, and reasonably acceptable to the Borrowers, which makes an Accordion Commitment and becomes a “Lender” obligated to make Warehousing Advances pursuant to the terms and conditions of the Accordion Loan Documents.

“Accordion Loan Documents” means such amendments, restatements, and modifications of the existing Loan Documents, together with any additional documents, instruments and agreements, deemed necessary or desirable in the sole discretion of the Credit Agent to evidence and effectuate a Successful Accordion Syndication, and the resulting increase to the Warehousing Commitment Amount, all of the foregoing in form and substance satisfactory to the Credit Agent, the Borrower, the Accordion Lenders, and the Required Lenders if the Lenders would be adversely affected thereby (or if otherwise required by this Agreement).

“Successful Accordion Syndication” means the arrangement of commitments from one or more Accordion Lenders by the Credit Agent, on terms and conditions acceptable to the Credit Agent in all respects, resulting in an increase in the Warehousing Commitment Amount by the amount requested by the Borrowers in the Accordion Notice (or such lesser amount as may be agreed upon by the Credit Agent and the Borrower) pursuant to the Accordion Loan Documents.
