EXHIBIT 10.6

        FIRST AMENDMENT TO MORTGAGE LOAN PURCHASE AND SALE AGREEMENT
        ------------------------------------------------------------

            This First Amendment dated as of September 1, 2004, is to that
certain Mortgage Loan Purchase and Sale Agreement (Whole Loan Purchase and Sale
Agreement) dated January 1, 2004 (the "P&S Agreement") by and between Greenwich
Capital Financial Products, Inc. ("Purchaser"), American Home Mortgage Corp. (a
"Seller") and American Home Mortgage Servicing, Inc. f/k/a Columbia National
Incorporated (a "Seller", and together with American Home Mortgage Corp., the
"Sellers");

            WHEREAS, Purchaser and Sellers have entered into the P&S Agreement;

            WHEREAS, Purchaser and Sellers desire to amend the P&S Agreement in
certain respects;

            NOW, THEREFORE, the parties, intending to be legally bound, amend
the P&S Agreement as follows:

      1. Effective as of the date hereof, Section 1 of the P&S Agreement is
hereby amended by replacing or adding the following definitions:

      "Hedge Trade": means a forward or other trade available to be assigned by
Sellers to Purchaser through a Trade Assignment in the event Purchaser exercises
its right to accept assignment of such Trade Assignment. In every circumstance
in which a Seller assigns a Hedge Trade, the amount of Mortgage Loans available
to be sold into the Hedge Trade and all other aspects of the Hedge Trade shall
be acceptable to Purchaser in its sole discretion.

      "Trade Assignment": The assignment by a Seller to Purchaser of the related
Seller's rights under a specific Takeout Commitment, in the form of Exhibit D-1,
or of the related Seller's rights under all Takeout Commitments, in the form of
Exhibit D-2, or of the related Seller's rights under a Hedge Trade, in the form
acceptable to Purchaser in its sole discretion.

      "Trade Price": Either (a) the trade price set forth on a Takeout
Commitment less any applicable Price Adjustment, or (b) in the event there is no
Takeout Commitment, the trade price established by Purchaser.

      2. Effective as of the date hereof, Section 2 of the P&S Agreement is
hereby restated to read in its entirety as follows:

            (a) Purchaser may, in its sole discretion, from time to time,
purchase one or more Mortgage Loan Pools from Sellers. Prior to Purchaser's
actual purchase of any Mortgage Loan Pool, the applicable provisions of Section
4 of the Custodial Agreement shall have been satisfied and Purchaser shall have
received from Custodian (i) by facsimile, a Notice of Intent to Issue Trust
Receipt, (ii) a copy of the Takeout Confirmation, if applicable, related to the
Mortgage Loan(s) in such Mortgage Loan Pool, together with a Trade Assignment in
the form of Exhibit


<PAGE>

D-1 or Exhibit D-2, executed by the related Seller and Takeout Investor, (iii)
an original letter in the form of Exhibit B-1 (an "Exhibit B-1 Letter") from the
applicable Warehouse Lender (if any), or an original letter in the form of
Exhibit C-1 (an "Exhibit C-1 Letter") in the event that there is no Warehouse
Lender, and (iv) shall have the right to receive in transactions in which the
Seller is not providing a Takeout Commitment, from the related Seller a report
generated by the related Seller demonstrating that Hedge Trades exist and are
available to be assigned to Purchaser in an amount and of a kind sufficient to
hedge all Mortgage Loans purchased by Purchaser from the related Seller for
which no Trade Assignments exist.

            (b) Simultaneously with the payment by Purchaser of the Purchase
Price, in accordance with the Warehouse Lender's Wire Instructions or Seller's
Wire Instructions, as applicable, with respect to a Mortgage Loan Pool, the
related Seller will have conveyed to Purchaser all of the related Seller's
right, title and interest in and to the related Mortgage Loan(s) free and clear
of any lien, claim or encumbrance. Upon payment of the Purchase Price, the Trust
Receipt covering all Mortgage Loans (including the Mortgage Loan Pool being
purchased) shall be delivered in accordance with the provisions of the Custodial
Agreement by facsimile with the original Trust Receipt to be sent by overnight
mail to arrive on the Business Day after the day it is sent by facsimile.
Notwithstanding the satisfaction by the related Seller of the conditions
specified in this Section 2, prior to the payment by Purchaser of the Purchase
Price (or the execution of any written commitment by the Purchaser to purchase
any specific Mortgage Loans hereunder), Purchaser is not obligated to purchase
any Mortgage Loans offered to it hereunder.

            (c) If Purchaser elects to purchase any Mortgage Loan Pool,
Purchaser shall pay the amount of the Purchase Price for such Mortgage Loan Pool
by wire transfer of immediately available funds in accordance with the
provisions of the Custodial Agreement and the Warehouse Lender's Wire
Instructions or if there is no Warehouse Lender, Seller's Wire Instructions.
Upon such payment and not otherwise, Purchaser shall be deemed to have accepted
the related Trade Assignment. Sellers shall not offer for sale to Purchaser any
Mortgage Loan as to which the Expiration Date of any related Takeout Commitment
is two (2) Business Days or less following the Purchase Date.

            (d) In the event that Purchaser rejects a Mortgage Loan for purchase
for any reason and does not transmit the applicable Purchase Price, Purchaser
shall not consummate the transactions contemplated in the applicable Takeout
Confirmation or Hedge Trade with respect to any such Mortgage Loan and shall
deliver to Takeout Investor (with a copy to the related Seller and Custodian) a
Notice of Rejection of Trade Assignment, provided, however, that failure of
Purchaser to give such notice shall not affect the rejection by Purchaser of the
Trade Assignment, and if Purchaser shall nevertheless receive any portion of the
related Takeout Proceeds, Purchaser shall promptly pay such Takeout Proceeds to
the related Seller in accordance with Seller's Wire Instructions.

            (e) The terms and conditions of the purchase of each Mortgage Loan
Pool shall be as set forth in this Agreement.

                                       2
<PAGE>

            (f) In the event the related Seller does not deliver to Purchaser a
Takeout Commitment and related Trade Assignment on the date Purchaser purchases
Mortgage Loans, the related Seller shall have thirty (30) days from the Purchase
Date to either (i) deliver to Purchaser a Takeout Commitment and related Trade
Assignment, or (ii) or repurchase the subject Mortgage Loans from Purchaser. In
the event, the related Seller fails to deliver timely such Takeout Commitment
and Trade Assignment or repurchase the Mortgage Loans, the related Seller shall
have waived its right to receive the Completion Fee otherwise payable in
accordance with Section 4 hereof and Purchaser may, at any time thereafter,
demand an assignment of appropriate Hedge Trades sufficient in Purchaser's
reasonable judgment to hedge fully the Mortgage Loans purchased by Purchaser
from Seller for which no Takeout Commitment and related Trade Assignment exists.

      3. Effective as of the date hereof, Sections 3(a) and (b) of the P&S
Agreement are hereby restated to read in their entirety as follows:

            (a) With respect to Mortgage Loan(s) that Purchaser has elected to
purchase and in the event there exists a Takeout Commitment, Purchaser may, at
its option, either (i) instruct Custodian to deliver to Takeout Investor, in
accordance with Takeout Investor's instructions, the Custodial File in respect
of such Mortgage Loans, in the manner and at the time set forth in the Custodial
Agreement, or (ii) provide for the delivery of the Custodial File through an
escrow arrangement satisfactory to Purchaser and Takeout Investor. In the event
that a Takeout Investor exists, the related Seller shall, within ten (10)
Business Days following the Purchase Date, but in no event later than two (2)
Business Days prior to the related Expiration Date, deliver to Takeout Investor
the related Credit File and thereafter any and all additional documents
requested by Takeout Investor to enable Takeout Investor to purchase such
Mortgage Loan(s) on or before the related Expiration Date.

            (b)(1) Subject to the provisions of Section 4(e) herein, except when
Purchaser has accepted a Settlement Modification Letter, unless the Takeout
Proceeds are received by Purchaser (in immediately available funds in accordance
with Purchaser's Wire Instructions) with respect to the Mortgage Loans in a
Mortgage Pool, on or before the related Cure Date, the Completion Fee relating
to such Mortgage Pool shall not be payable until the earlier to occur of (1) the
date of receipt by Purchaser of the Takeout Proceeds and, (2) the satisfaction
by the related Seller of its obligations pursuant to the exercise by Purchaser
of any remedial election authorized by this Section 3. Upon receipt by
Purchaser, prior to the Cure Date, of a Settlement Modification Letter, duly
executed by Takeout Investor and the related Seller, Purchaser may, at its
election, agree to the postponement of the Settlement Date and such other
matters as are set forth in the Settlement Modification Letter. If Purchaser
elects to accept a Settlement Modification Letter, Purchaser shall, not later
than two (2) Business Days after receipt of such Settlement Modification Letter
execute the Settlement Modification Letter and send, via facsimile, copies of
such fully executed Settlement Modification Letter to the related Seller and
Takeout Investor. Subject to the provisions of Section 4(e) herein, upon
execution by Purchaser of a Settlement Modification Letter, Purchaser shall
recalculate the amount of the Completion Fee, if any, due to the related Seller
using the new terms included in the Settlement Modification


                                       3
<PAGE>

Letter and shall pay to the related Seller, not later than two (2) Business Days
after Takeout Investor's purchase of the related Mortgage Loans pursuant to such
Settlement Modification Letter, the amount of such recalculated Completion Fee.

            (b)(2) In the event that the related Seller fails to deliver within
thirty (30) days from the Purchase Date a Takeout Commitment and Trade
Assignment, the related Seller shall have waived its right to receive the
Completion Fee otherwise payable in accordance with Section 4 hereof.

      4. Effective as of the date hereof, Section 4(a) of the P&S Agreement is
hereby restated to read in its entirety as follows:

            (a) Subject to paragraph 2(f), 4(d) and 3(b)(2), with respect to
each Mortgage Loan Pool that Purchaser elects to purchase hereunder, Purchaser
shall pay to the related Seller a Completion Fee. In the event that the
Completion Fee is payable by Purchaser in connection with any Mortgage Loan
Pool, it shall be paid by Purchaser as provided in subsection (d) below.

      5. Effective as of the date hereof, Section 4(d) of the P&S Agreement is
hereby restated to read in its entirety as follows:

            (d) In the event that a Seller delivers to Purchaser a Takeout
Commitment through a Trade Assignment (other than a Hedge Trade) in accordance
with Section 2 hereof, the Completion Fee relating to each Mortgage Loan Pool is
payable on the earlier to occur of (1) the date of receipt by Purchaser of the
Trade Price, and (2) the satisfaction by the related Seller of its obligations
pursuant to this Agreement notwithstanding the exercise by Purchaser of any
remedial election authorized herein. In the event, the related Seller fails to
deliver timely such Takeout Commitment and Trade Assignment in accordance with
Section 2(f), the related Seller shall have waived its right to receive the
Completion Fee.

      6. Effective as of the date hereof, Section 6 of the P&S Agreement is
hereby restated to read in its entirety as follows:

            Section 6. Trade Assignments. To the extent Purchaser (i) elects to
      accept any Trade Assignment and (ii) pay the Discount to the related
      Seller in accordance therewith, the related Seller hereby assigns to
      Purchaser, free of any security interest, lien, claim or encumbrance of
      any kind, the related Seller's rights, under each Takeout Commitment or
      Hedge Trade to deliver the Mortgage Loan(s) specified therein to the
      related Takeout Investor or counter-party and to receive the Takeout
      Proceeds therefor from such Takeout Investor or amounts owed under the
      Hedge Trade, as applicable. Purchaser shall not be deemed to have accepted
      any Trade Assignment unless and until it purchases the related Mortgage
      Loans, and nothing set forth herein shall be deemed to impair Purchaser's
      right to reject any Mortgage Loan for any reason, in its sole discretion.



                                       4
