                       FIFTH AMENDED AND RESTATED SECURITY
                         AND COLLATERAL AGENCY AGREEMENT

      THIS FIFTH AMENDED AND RESTATED SECURITY AND COLLATERAL AGENCY AGREEMENT
(the "Security Agreement") is made and dated as of May ___, 2006 by and among
PULTE MORTGAGE LLC , a Delaware limited liability company (the "Company"),
JPMORGAN CHASE BANK, N.A., a national banking association, acting in its
capacity as administrative agent for the Lenders from time to time parties to
the Credit Agreement (as defined below) (in such capacity, the "Credit Agent"),
and LASALLE BANK NATIONAL ASSOCIATION, as collateral agent for the Secured
Parties (as defined below) (in such capacity, the "Collateral Agent").

                                    RECITALS

      A. Pursuant to that certain Sixth Amended and Restated Revolving Credit
Agreement of even date herewith, by and among the Company, the Credit Agent and
certain other Lenders named therein (the "Credit Agreement"), the Lenders agreed
to extend credit to the Company on the terms and subject to the conditions set
forth therein. Capitalized terms not otherwise defined herein are used with the
same meanings as in the Credit Agreement.

      B. As a condition precedent to the effectiveness of the Credit Agreement,
the Credit Agent has required the execution and delivery of this Security
Agreement in order to, among other things, create a first priority perfected
security interest in the Collateral in favor of the Lenders, the Credit Agent
and the Collateral Agent (collectively, the "Secured Parties") to secure payment
of the Secured Obligations.

      C. This Security Agreement amends and restates in its entirety that
certain Fourth Amended and Restated Security and Collateral Agency Agreement
dated as of June 30, 2004 by and among the Company, the Credit Agent and the
Collateral Agent.

      NOW, THEREFORE, in consideration of the above Recitals and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties hereto agree as follows:

                                   AGREEMENTS

      1. Appointment of Collateral Agent. Each Lender has, pursuant to the terms
of the Credit Agreement, appointed the Collateral Agent to act as secured party,
agent, bailee and custodian for the exclusive benefit of the Secured Parties
with respect to the Collateral. The Collateral Agent hereby accepts such
appointment and agrees to maintain and hold, or cause to be maintained and held,
all Collateral at any time delivered to it or any of its subagents as secured
party, agent, bailee and custodian for the exclusive benefit of the Secured
Parties. The Collateral Agent and the Company agree that the Collateral Agent is
acting and will act with respect to the Collateral for the exclusive benefit of
the Secured Parties and is not, and shall not at any time in the future be,
subject, with respect to the Collateral, in any manner or to any extent, to the
direction or control of the Company except as expressly permitted hereunder and
under the other Loan Documents. The Collateral Agent agrees to act in accordance
with this Security Agreement and in accordance with any written instructions
properly delivered pursuant hereto. Under no circumstances shall the Collateral
Agent deliver, or cause to be delivered, possession of Collateral to the Company
except in accordance with the express terms of this Security Agreement or the
other Loan Documents.

      2. Delivery and Categorization of Collateral.

            (a) Mortgage Loans. The Company shall deliver Collateral
Transmittals to the Collateral Agent from time to time identifying Mortgage
Loans that the Company intends to include in Collateral by delivering to the
Collateral Agent the Required Mortgage Documents (as described on Schedule A
attached hereto) for such Mortgage Loans. Such delivery shall be made prior to
inclusion of such Mortgage Loans in Collateral, other than for AP Mortgages
identified in the Collateral Transmittal and covered by an Agreement to Pledge.
The Collateral Agent shall review the Required Mortgage Documents in accordance
with the review steps described on Exhibit 1 hereto.

            (b) Agreement to Pledge. The Collateral Agent, upon receipt of a
Collateral Transmittal describing the AP Mortgages to be covered by an AP Notice
and an Agreement to Pledge as of that date, shall (subject to the eligibility
requirements set forth in the Credit Agreement) include such AP Mortgages as
Eligible Collateral in the Collateral Value Determination (as defined Paragraph
6(a) below). The Company shall deliver the Required Mortgage Documents for each
such AP Mortgage not later than the ninth (9th) Business Day after the date such
AP Mortgage is first so included as an Eligible Collateral. When a delivery of
what purports to be the Required Mortgage Documents for an AP Mortgage is
received by the Collateral Agent on a given Business Day, such AP Mortgage shall
no longer be treated as an AP Mortgage for purposes of the Borrowing Base
Sublimits, and shall be included in any Collateral Value Determination or other
calculation involving the value of the Borrowing Base on such Business Day prior
to the Collateral Agent's review thereof on the assumption that such AP Mortgage
is Eligible Collateral. The Collateral Agent shall review such Required Mortgage
Documents in accordance with the steps described on Exhibit 1 hereto before the
opening of business of the Collateral Agent on the next succeeding Business Day
and shall make a decision on the eligibility of the applicable Mortgage Loan for
that Business Day.

            (c) Securities. The Company may, from time to time, deliver
Securities to the Collateral Agent or an Approved MBS Custodian and shall
provide evidence that such Securities are either (a) in a certificated form,
with the certificates evidencing such Securities being delivered to the
Collateral Agent or such Approved MBS Custodian, or (b) in book entry or
uncertificated form with evidence that the Collateral Agent or such Approved MBS
Custodian has been identified as the nominal owner of such Securities in the
records of a Federal Reserve Bank or other institution authorized by the
applicable Federal Agency to maintain ownership records in respect of such
Securities.

            (d) Gestation Collateral. The Company may, from time to time,
deliver a request to the Collateral Agent (or an Affiliate of the Collateral
Agent) acting in its capacity as pool custodian, for the initial certification
of Pledged Mortgages for purposes of creating a pool of Mortgage Loans to
support the issuance of a FHLMC, FNMA or GNMA Security. Such request shall be in
writing in the form of Exhibit 3.A to this Security Agreement, and such Pledged
Mortgages shall constitute Gestation Mortgage Loans on the Business Day
immediately following the Business Day on which such Pledged Mortgages are
certified by the Collateral Agent (or an Affiliate of the Collateral Agent) in
accordance with the standards of the applicable Federal Agency.

            (e) Pledged Servicing. The Company shall deliver to the Collateral
Agent fully executed copies of the Acknowledgment Agreements with FNMA and
FHLMC. In the event the Credit Agent or the Required Lenders request that
Acknowledgement Agreements with GNMA be obtained, the Company shall deliver to
the Collateral Agent fully executed copies of Acknowledgement Agreements with
GNMA covering all Pledged Servicing with GNMA.

                                     - 2 -

<PAGE>

            (f) Servicing Sale Receivables. The Company may, in connection with
a sale of Servicing Agreements from the Company to a Servicing Purchaser, pledge
the Servicing Sale Receivables due in connection with such sale to the
Collateral Agent for the benefit of the Secured Parties as Collateral. If the
Company so pledges Servicing Sale Receivables to the Collateral Agent, the
Company shall (i) deliver to the Credit Agent and the Collateral Agent a
complete executed copy of the related purchase agreement, (ii) assign its rights
to such Pledged Servicing Sale Receivables to the Collateral Agent for the
benefit of the Secured Parties pursuant to an assignment in form and content
satisfactory to the Credit Agent, and (iii) cause the Servicing Purchaser of the
applicable sold Servicing Agreements to execute an agreement in form and content
satisfactory to the Credit Agent pursuant to which the Servicing Purchaser shall
agree to (A) pay such Pledged Servicing Sale Receivables directly to the
Collateral Agent for the benefit of the Secured Parties, and (B) provide
simultaneous written notice to the Credit Agent and the Collateral Agent of any
claims made against or notices given to the Company which would constitute an
offset to or reduction in the amount of such Pledged Servicing Sale Receivables.

            (g) Identification of Collateral. All Mortgage Loans and Securities
at any time delivered to the Collateral Agent hereunder shall be held by the
Collateral Agent in a fire resistant vault, drawer or other suitable depositary
maintained in accordance with Federal Agency standards and controlled solely by
the Collateral Agent, conspicuously marked to show the respective interests of
the Secured Parties therein and not commingled with any other assets or property
of, or held by, the Collateral Agent. Accordingly, if (pursuant to Paragraph
7(b) below) the Collateral Agent receives a shipping request pursuant to which
the Collateral Agent is to retain physical possession of the applicable Mortgage
Loans or Securities as an agent for any Person other than the Secured Parties,
the Collateral Agent shall physically separate such Mortgage Loans or Securities
from the remainder of the Collateral and shall execute any transmittal letters
required under Paragraph 7(b) below.

      3. Grant of Security Interest. The Company hereby pledges and assigns to
the Collateral Agent for the benefit of the Secured Parties and grants to the
Collateral Agent for the benefit of the Secured Parties, a first priority
security interest in, the property described in Paragraph 4 below (collectively
and severally, the "Collateral"), to secure payment of the Secured Obligations.
Furthermore, each Agreement to Pledge shall create a security interest in favor
of the Collateral Agent for the benefit of the Secured Parties in the AP
Mortgages identified therein. By delivering an Agreement to Pledge, the Company
represents and warrants that each AP Mortgage identified therein constitutes an
Eligible Mortgage Loan. The Company agrees that while it is in possession of any
Required Mortgage Documents for an AP Mortgage, it will hold same in trust and
as agent and bailee for the Collateral Agent for the benefit of the Secured
Parties, without authority to make any other disposition thereof, or of the
proceeds thereof. The Company assumes the responsibility for loss or destruction
of any such Required Mortgage Documents until the same are delivered to the
Collateral Agent.

      Unless so directed by the Credit Agent when a Default has occurred and is
continuing, the Collateral Agent shall not record the assignment of mortgage or
deed of trust delivered in connection with any Pledged Mortgage.

      4. Collateral. The Collateral shall consist of all right, title and
interest of the Company of every kind and nature in and to all of the following
property, assets and rights of the Company wherever located, whether now
existing or hereafter arising, and whether now or hereafter owned or acquired by
or accruing or owing to the Company, and all proceeds and products thereof
(including all proceeds in the Settlement Account, the Cash and Collateral
Account and any Custodian Settlement Accounts from time to time):

                                     - 3 -

<PAGE>

            (a) all Pledged Mortgages;

            (b) all Pledged Securities;

            (c) any commitments or other agreements issued by any private
mortgage insurer or by the FHA or VA to insure or guarantee any Pledged
Mortgage;

            (d) all commitments of FNMA, FHLMC or other Persons to purchase
Pledged Items from the Company or exchange Securities with the Company for
Pledged Items;

            (e) any options to sell or purchase Securities, future contracts, or
any other interest rate protection products which directly or indirectly protect
the Company against reductions in value of such Pledged Items due to changes in
mortgage interest rates;

            (f) the Settlement Account, the Cash and Collateral Account and any
Custodian Settlement Accounts and any amounts standing to the credit of the
Settlement Account, the Cash and Collateral Account and any Custodian Settlement
Accounts then in existence with Approved MBS Custodians, as described in
Paragraph 7(c) below;

            (g) all cash and Cash Equivalents held by the Credit Agent or
Collateral Agent as security for the Secured Obligations;

            (h) all Pledged Servicing;

            (i) all Pledged Servicing Sale Receivables;

            (j) all property related to the foregoing, including, without
limitation, the right to service Pledged Mortgages while owned by the Company,
all accounts and general intangibles of whatsoever kind so related and all
documents or instruments delivered to the Credit Agent or the Collateral Agent
in respect of any Pledged Item, including, without limitation, the right to
receive all insurance proceeds and condemnation awards which may be payable in
respect of the premises encumbered by any Pledged Mortgage; and

            (k) all proceeds and products of any of the foregoing.

      5. Collateral Agent's Review of Collateral. Upon any receipt of Required
Mortgage Documents for any Mortgage Loan, the Collateral Agent shall review the
same and verify that:

            (a) All Required Mortgage Documents relating to such Mortgage Loan
appear regular on their face (as determined by the Collateral Agent in its
reasonable discretion) and are in the Collateral Agent's possession; and

            (b) The statements set forth on Exhibit 1 hereto are accurate and
complete in all material respects.

If the Collateral Agent notes any exception in the review described in
subparagraph (a) or (b) above, the Collateral Agent shall not include such item
as Eligible Collateral in its next Collateral Value Determination (as defined in
Paragraph 6(a) below) delivered to the Credit Agent. In the event that the
Company has been requested by the Credit Agent or the Collateral Agent to
deliver the "Additional Required Mortgage Documents" (as described on Schedule B
attached hereto) with respect to any

                                     - 4 -

<PAGE>

Mortgage Loan, the Collateral Agent shall review and verify such Additional
Required Mortgage Documents consistent with the obligations of the Collateral
Agent above. However, the Collateral Agent shall have no obligation to verify
that (i) the amount of any fire and extended coverage insurance policy meets the
requirements set forth on Schedule B, or (ii) the loan to value ratio for any
mortgage note is in excess of 80% (and thus whether private mortgage insurance
is required), but shall be entitled to rely upon the determinations of the
Company with respect to these matters.

      6. Collateral Value Determination; Determination Assumptions.

            (a) On each Business Day the Collateral Agent shall compute the
value of the Borrowing Base (taking into account all Borrowing Base Sublimits),
the Servicing Borrowing Base, the Non-Gestation Borrowing Base and the Gestation
Borrowing Base (collectively, the "Borrowing Bases") and notify the Credit Agent
thereof (a "Collateral Value Determination") by telephone and by sending a
facsimile copy of a report ("Borrowing Base Report") in the form of Schedule C
hereto (or such other form as may be mutually agreed to by the Collateral Agent
and the Credit Agent) prior to 11:00 a.m. (New York City time).

            (b) In making any Collateral Value Determination or other
calculation involving a determination of the value of the Borrowing Bases, the
Collateral Agent shall be permitted to rely, without independent investigation
of the correctness thereof, on:

                  (1) The information supplied by the Company to the Collateral
      Agent on the related Collateral Transmittal, with respect to the net
      acquisition cost (including any discounts and excluding any servicing
      released premium) of any Mortgage Loan, the unpaid principal balance of
      any Mortgage Loan as of the Pledge Date therefor, and the weighted average
      purchase price (expressed as a percentage of par) committed to under all
      Approved Investor Commitments which could cover such Mortgage Loan (which
      weighted average purchase price shall be recalculated by the Company and
      reported to the Collateral Agent weekly);

                  (2) The most recent information supplied by the Company to the
      Collateral Agent with respect to the number of days by which payments on
      any Mortgage Loan constituting Collateral are past due;

                  (3) The written information supplied by the Company to the
      Collateral Agent with respect to a determination as to whether amounts
      received in the Cash and Collateral Account represent the purchase price
      paid for a specific Mortgage Loan or Security and, consequently, whether
      the Mortgage Collateral Value of such Mortgage Loan or MBS Value of such
      Security should be removed from such calculation;

                  (4) The most recent information supplied by the Credit Agent
      to the Collateral Agent with respect to the amount of the then current
      Aggregate Commitment, which information, if requested by the Collateral
      Agent, shall be reported by the Credit Agent to the Collateral Agent by
      10:30 a.m. (New York City time) on the first Business Day after such
      request;

                  (5) Any information supplied by the Credit Agent, the Company,
      or any other custodian of any of the Collateral, to the Collateral Agent
      unless the Collateral Agent has actual knowledge that such information is
      untrue or unreliable; and

                                     - 5 -

<PAGE>

                  (6) The information supplied by the Company or the Credit
      Agent with respect to the Aggregate Servicing Value of the Eligible
      Mortgage Servicing Rights and Eligible Servicing Sale Receivables.

            (c) No later than 4:30 p.m. (New York City time) on each Business
Day (the "Information Cutoff Time") the Company shall deliver to the Collateral
Agent a list of Pledged Items (other than, so long as no Default exists,
Securities or Gestation Mortgage Loans being pooled and sold, the sale of which
is addressed in Paragraph 6(d) below) that have been sold to investors (or, in
the case of Servicing Sale Receivables, the applicable Servicing Sale
Receivables to be received on such day) (the "Paid Collateral Listing"),
together with appropriate detail identifying the specific wire that represents
the proceeds of each Pledged Item on the Paid Collateral Listing. Upon receipt
of the Paid Collateral Listing by the Information Cutoff Time, the Collateral
Agent will confirm with the Credit Agent the results of the Credit Agent's
review of all wires received in the Cash and Collateral Account on or before
4:00 p.m. (New York City time) (the "Wire Cutoff Time") and confirm with the
Credit Agent that the wires detailed in the Paid Collateral Listing have been
received in the Cash and Collateral Account and that the actual amounts match
those shown in the Paid Collateral Listing (the "Paid Reconciliation Process").
Any Pledged Item identified on the Paid Collateral Listing that cannot be
reconciled by the Collateral Agent will remain in the Borrowing Base and the
associated settlement proceeds will remain in the Cash and Collateral Account
until such time as the Collateral Agent receives the necessary information from
the Company to complete the Paid Reconciliation Process. On or before 5:30 p.m.
(New York City time), the Collateral Agent will remove the reconciled Pledged
Items from the Borrowing Base, and notify the Credit Agent of (i) the amount of
reconciled proceeds ("Reconciled Non-Security Proceeds") and (ii) an updated
Collateral Value Determination reflecting the removal of such Pledged Items. No
later than 5:00 p.m. (New York City time), the Collateral Agent will notify the
Company of the amount of Reconciled Non-Security Proceeds and, so long as the
updated Borrowing Base exceeds the total unpaid balance of the outstanding Loans
and no Default exists, authorize the Credit Agent to transfer such amounts from
the Cash and Collateral Account to the Company's operating account or as
otherwise instructed by the Company. If the Borrowing Base does not exceed the
total unpaid balance of the outstanding Loans, the Collateral Agent shall
authorize the Credit Agent to apply the necessary amount of such Reconciled
Non-Security Proceeds against the outstanding Loans in accordance with Section
8.4 of the Credit Agreement so that the Borrowing Base equals or exceeds the
total unpaid balance of the outstanding Loans and transfer the balance of such
proceeds to the Company as set forth above. During the continuance of a Default,
all proceeds shall be applied in accordance with the terms of Section 8.4 of the
Credit Agreement.

            (d) The procedures set forth in this Paragraph 6(d) will apply for
sales of Gestation Mortgage Loans and/or Securities on Pool Settlement Days, so
long as no Gestation Default has occurred or would result therefrom (in which
case the procedures described in Paragraph 6(c) shall apply). During the
continuance of a Default, all pool settlement proceeds shall be applied in
accordance with the terms of Section 8.4 of the Credit Agreement. For purposes
of this agreement, "Pool Settlement Days" shall be defined as any day on which a
pool of Gestation Mortgage Loans is funded by the applicable settlement agent.
No later than 3:00 p.m. (New York City time) on each Pool Settlement Day the
Company shall deliver to the Collateral Agent a list of pooled Gestation
Mortgage Loans that support Securities which are expected to settle on such day
(the "Pool Out Report"), together with appropriate detail identifying the
specific wire that represents the proceeds of each pool that the Company expects
to receive no later than the close of business on that same day. On or before
2:00 p.m. (New York City time), upon notice from the Company that a payment is
scheduled to be made that day, the Credit Agent may elect, pursuant to Section
2.17 of the Credit Agreement, to pay down any outstanding Loans designated by
the Company to be repaid based on the expectation that the wire for

                                     - 6 -

<PAGE>

these proceeds (the "Pool Proceeds") will be received. At or about 5:30 p.m.
(New York City time), the Collateral Agent will authorize the Credit Agent to
repay itself the amounts advanced pursuant to the preceding sentence with the
applicable amount of the Pool Proceeds at or about 5:30 p.m. (New York City
time). The Credit Agent will notify the Company if any expected Pool Proceeds
have not been received by 4:30 p.m. (New York City time). Any shortfall still
owed to the Credit Agent resulting from a negative variance between the total
expected Pool Proceeds and the actual Pool Proceeds received on or before 5:30
p.m. (New York City time), shall be covered by a Swingline Advance equal to the
shortfall amount. Such Swingline Advance will be made automatically without need
for a request by the Company and will accrue interest at the LIBOR Rate. Should
the required amount exceed the Swingline availability, the remaining unpaid
amount advanced by the Credit Agent (the "Overadvance") shall accrue interest at
the LIBOR Rate. On or before the time at which the first determination of the
Borrowing Base is prepared on the next Business Day, the Collateral Agent will:
(i) confirm with the Credit Agent that the remaining expected Pool Proceeds were
received in the Cash and Collateral Account and that the actual amounts of all
the Pool Proceeds match the amounts on the Pool Out Report, and (ii) remove from
the Borrowing Base the Gestation Mortgage Loans which were pooled and sold. If
all or a portion of the expected remaining Pool Proceeds are not received in the
Cash and Collateral Account on or before the time at which the Borrowing Base is
first prepared on the next Business Day, the Gestation Mortgage Loans related to
the expected remaining Pool Proceeds will remain in the Borrowing Bases as long
as they remain eligible. The Credit Agent will use all Pool Proceeds received
from the Cash and Collateral Account to repay the unpaid amounts advanced by the
Credit Agent above, and then shall apply any remaining Pool Proceeds ("Excess
Pool Proceeds") as set forth in Section 8.4 of the Credit Agreement. To the
extent that the Pool Proceeds are insufficient to repay all unpaid Overadvances,
the Credit Agent shall request repayment of such funds from the Lenders,
together with interest, in accordance with Section 2.17 of the Credit Agreement.

      7. Handling of Collateral; Designation of Accounts.

            (a) From time to time until otherwise notified in writing by the
Required Lenders, the Collateral Agent is hereby authorized to release
documentation relating to Mortgage Loans to the Company against a trust receipt
executed by the Company in the form of Exhibit 2 hereto (with such documents to
be returned within 15 Business Days as set forth in such Exhibit 2, failing
which the applicable Mortgage Loan shall cease to be Eligible Collateral). The
Collateral Agent will maintain all original trust receipts in a vault, drawer or
other suitable depositary with a one hour fire rating maintained in accordance
with Federal Agency requirements and controlled solely by Collateral Agent. The
Company hereby represents and warrants that any request by the Company for
release of Collateral under this subparagraph (a) shall be solely for the
purposes of correcting clerical or other non-substantial documentation problems
in preparation of returning such Collateral to the Collateral Agent for ultimate
sale or exchange and that the Company has requested such release in compliance
with all terms and conditions of such release set forth herein and in the Credit
Agreement.

            (b) Prior to the occurrence of a Default, upon delivery by the
Company to the Collateral Agent of a shipping request substantially in the form
of that attached hereto as Exhibit 3.B, the Collateral Agent will transmit, or
cause to be transmitted, Mortgage Loans and Securities held by it or any
Approved MBS Custodian as directed by the Company as follows:

                  (1) If the transmittal is of documentation for Mortgage Loans
      or Securities in the possession of the Collateral Agent or an Approved MBS
      Custodian in connection with the sale thereof to an Approved Investor,
      such transmittal will be under cover of a transmittal letter substantially
      in the form of that attached hereto as Exhibit 4 (or such other form as
      may be approved by the Credit Agent or required under any Federal Agency
      program pursuant to which

                                     - 7 -

<PAGE>

      the relevant Mortgage Loans or Securities are being shipped) , subject to
      modification of such Exhibit 4 pursuant to Paragraph 7(g) hereof at the
      request of the Credit Agent. The Company is hereby authorized to direct
      the Collateral Agent from time to time to transmit the documentation for
      Pledged Mortgage Loans being sold to an Approved Investor along with the
      documentation for other mortgage loans pledged for the benefit of other
      lenders and being sold to the same Approved Investor pursuant to a single
      transmittal letter in the form of Exhibit 4 which includes the optional
      language bracketed in Exhibit 4 (the "Joint Transmittal Letter").

                  (2) If the transmittal is of documentation for Mortgage Loans
      or Securities in connection with the shipment to a custodian or trustee
      (including any Affiliate of the Collateral Agent) in connection with the
      formation of a mortgage pool supporting a Security (any such Security
      secured or otherwise supported by any such Mortgage Loan or Security being
      referred to herein as a "Warehouse-Related Security"), such transmittal
      will be under cover of a transmittal letter substantially in the form of
      that attached hereto as Exhibit 5 (or such other form as may be required
      if the Security is being issued under any Federal Agency program), subject
      to modification of such Exhibit 5 pursuant to Paragraph 7(g) hereof at the
      request of the Credit Agent, and, in addition, will be conditioned upon
      the facts that:

                        (i) If the Warehouse-Related Security is being issued
            under a Federal Agency program, there has been delivered for the
            Warehouse-Related Security such form as may be required under the
            Federal Agency program pursuant to which such Warehouse-Related
            Security is being issued (which form shall name the Collateral Agent
            or an Approved MBS Custodian (as defined below) as the subscriber
            and the Person to whom the Warehouse-Related Security is to be
            delivered);

                        (ii) If the Warehouse-Related Security is being issued
            pursuant to a program other than a Federal Agency program, there has
            been delivered to and acknowledged by the trustee and collateral
            agent or custodian for the underlying mortgage pool a letter in form
            substantially similar to Exhibit 5 and reasonably acceptable to the
            Collateral Agent;

                        (iii) The Person to whom such Warehouse-Related Security
            is to be delivered upon issuance in exchange for the Mortgage Loans
            or Securities being shipped is either (a) a Person approved by the
            Collateral Agent and the Credit Agent which has agreed to hold such
            Warehouse-Related Security and the proceeds of any sale or other
            disposition thereof as custodian, agent and bailee for the benefit
            of the Secured Parties pursuant to a custodial agreement
            substantially in the form of that attached hereto as Exhibit 6 (a
            "Custodial Agreement"), or (b) the Credit Agent, the Collateral
            Agent or an Affiliate thereof (any Person acting in such capacity
            being referred to herein as an "Approved MBS Custodian");

                        (iv) There has been delivered to the Approved MBS
            Custodian a letter in the form attached to the Custodial Agreement
            (Exhibit A to Exhibit 6 hereto); and

                        (v) At the request of the Credit Agent pursuant to
            Paragraph 7(g) hereof, any Warehouse-Related Security delivered to
            an Approved MBS Custodian pursuant to subparagraphs (i) through (iv)
            shall be in a face amount of not less than the amount of the
            Borrowing Base which is attributable to the Mortgage Loans so
            delivered in exchange for such Warehouse-Related Security.

                                     - 8 -

In no event shall the Collateral Agent have any obligation to obtain written
acknowledgement of receipt from the addressee of any transmittal letter or other
communication sent by the Collateral Agent hereunder.

            (c) All amounts payable on account of the sale of Pledged Items
(including, but not limited to, a sale pursuant to a repurchase agreement) will
be instructed to be paid directly by the purchaser to the Cash and Collateral
Account or, in the case of Pledged Securities delivered to an Approved MBS
Custodian, to a demand deposit account maintained with such Approved MBS
Custodian (a "Custodian Settlement Account") and, thereafter, to the Cash and
Collateral Account or the Settlement Account, as provided in the applicable
Custodial Agreement. Pursuant to Paragraph 3 above the Company has granted a
security interest in and lien upon the Settlement Account, the Cash and
Collateral Account and in all Custodian Settlement Accounts and in any and all
amounts at any time held therein as collateral security for the benefit of the
Secured Parties. This Paragraph 7(c) shall constitute notice to the Collateral
Agent and any Approved MBS Custodian of such security interest pursuant to the
Uniform Commercial Code of all relevant jurisdictions and any other law or
regulation requiring such notice. This Paragraph 7(c) shall further constitute
irrevocable notice to the Collateral Agent and any Approved MBS Custodian that
the accounts referred to in Paragraph 4(f) above are "no access" accounts to the
Company and the Collateral Agent except to the extent expressly permitted
hereunder. The Collateral Agent shall hold such security interest in and lien
upon the accounts referred to in Paragraph 4(f) above and all funds at any time
held therein for the benefit of the Secured Parties with all rights of a secured
party under the Uniform Commercial Code of all relevant jurisdictions.

            (d) Prior to the occurrence of a Default, the Collateral Agent and
any Approved MBS Custodian shall take such steps as they may be reasonably
directed from time to time by the Company in writing which are not inconsistent
with the provisions of this Security Agreement and the other Credit Documents
and which the Company deems necessary to enable the Company to perform and
comply with Approved Investor Commitments and with other agreements for the sale
or other disposition in whole or in part of Mortgage Loans and Securities.

            (e) The Collateral Agent may deliver any item of Collateral to the
Company or any other Person in accordance with the provisions of the Credit
Documents; provided, however, that the Collateral Agent shall not deliver and
shall incur no liability to the Company or any other Person for refusing to
deliver any item of Collateral to the Company or any other Person (other than
under existing Approved Investor Commitments) while a Default exists if the
Collateral Agent has been directed to refrain from so delivering Collateral by
the Required Lenders.

            (f) In addition to the releases of Collateral provided for in the
preceding subparagraphs of this Paragraph 7, upon the request of the Company
delivered from time to time to the Credit Agent and the Collateral Agent, the
Collateral Agent shall, with the prior written approval of the Credit Agent,
release Collateral specified in such notice from the lien of this Security
Agreement. The Credit Agent shall give its approval of such release if, but only
if, (i) at the time of such release no Default exists and no notice of a Default
has been issued that has not been cured, (ii) any payment under Section 2.8 of
the Credit Agreement which may be required as a result of such release has been
made so that the release of such Collateral will not create a violation of any
Lending Sublimit or Borrowing Base Sublimit, and (iii) if the Collateral to be
released is Pledged Servicing, such release is made in connection with the sale
of such Pledged Servicing by the Company; provided, however, that the Collateral
Agent may release Collateral while a Default exists or while a notice of Default
has been issued but not cured if such release is in connection with the sale of
Collateral pursuant to an existing Approved Investor Commitment with the
proceeds of such sale being deposited in the Cash and Collateral Account or the
Settlement Account. The Collateral Agent is authorized to execute and

                                     - 9 -

<PAGE>

deliver to the Company, on behalf of the Secured Parties, such UCC-3 partial
release forms or other evidence as may be required of any release permitted
hereunder.

            (g) Notwithstanding the provisions of Paragraph 7(b) above, the
Credit Agent may, at any time, require that the following modifications be made
to all of its transmittal letters or only to transmittal letters to certain
Approved Investors designated by the Credit Agent:

                        (i) The second sentence of the second full paragraph of
            the form of whole loan sale transmittal letter attached hereto as
            Exhibit 4 shall be deleted and replaced with the following sentence:

                  "Each of the Mortgage Loans is subject to a security interest
                  in favor of LaSalle Bank National Association (the "Collateral
                  Agent") on behalf of the Secured Parties, which security
                  interest shall be automatically released upon your remittance
                  of an amount equal to the greater of (1) the purchase price
                  for such Mortgage Loans (as set forth on the schedule attached
                  hereto), and (2) $________, which is the mortgage collateral
                  value assigned by the Collateral Agent to such Mortgage Loans.
                  Such amount shall be remitted by wire transfer to the
                  following account:"

            in which case the amount to be inserted in the blank in clause two
            of such revised provision shall be an amount equal to the amount of
            the Borrowing Base which is attributable to the Mortgage Loans being
            delivered pursuant to the transmittal letter;

                        (ii) The second sentence of the second full paragraph of
            the form of warehouse related security transmittal letter attached
            hereto as Exhibit 5 shall be deleted and replaced with the following
            sentence:

                  "Each of the Mortgage Loans is subject to a security interest
                  in favor of LaSalle Bank National Association (the "Collateral
                  Agent") for the benefit of the Secured Parties, which security
                  interest shall be automatically released upon the issuance of
                  the Warehouse-Related Security in accordance with the terms of
                  the prescribed GNMA, FNMA or FHLMC form enclosed herewith,
                  which form shall name a person designated by the Collateral
                  Agent as the person to whom the Warehouse-Related Security is
                  to be delivered and require that the principal amount of the
                  Warehouse Related Security be in an amount not less than
                  $______________, which is the mortgage collateral value
                  assigned by the Collateral Agent to such Mortgage Loans.",

            in which case the amount to be inserted in the blank in such revised
            provision shall be an amount equal to the amount of the Borrowing
            Base which is attributable to the Mortgage Loans being delivered
            pursuant to the transmittal letter.

      8. Reports. The Collateral Agent shall deliver (a) the Borrowing Base
Report to the Credit Agent at the times and in the manner set forth in Paragraph
6(a) above, (b) a Borrowing Base Report to the Company and each Lender on or
before the seventh day of each month, and (c) to the Credit Agent and any Lender
which makes a written request therefor, such other reports and information as
any Lender may from time to time reasonably request. In preparing any such
reports the Collateral Agent shall be entitled to rely, without independent
investigation (other than the review steps described on Exhibit 1 hereto), on
information supplied to the Collateral Agent by the Company. The Collateral
Agent may, with the approval of the Company and the Credit Agent, alter the
format of any report

                                     - 10 -

<PAGE>

required hereunder, provided such modified report contains the same information
previously furnished in the unmodified report.

      9. No Reliance. The Collateral Agent shall not be responsible to any
Secured Party for any recitals, statements, representations or warranties
contained herein or in any other Credit Document; or for the execution,
effectiveness, genuineness, validity, enforceability, collectability, accuracy,
completeness or sufficiency of this Security Agreement or any other Credit
Document or instruments executed and delivered, or which could have been
executed or delivered, in connection with this Security Agreement or the other
Credit Documents, including, without limitation, the attachment, creation,
effectiveness or perfection of the security interests granted or purported to be
granted hereunder in and to the Collateral.

      10. Intentionally Omitted.

      11. Availability of Documents. The Secured Parties and their agents,
accountants, attorneys and auditors (each an "Inspecting Party") will be
permitted from time to time upon not less than three Business Days' written
notice to the Collateral Agent and the Company, and at such time as may be
mutually acceptable to such Inspecting Party, the Collateral Agent and the
Company to examine (to the extent permitted by applicable law) the files,
documents, records and other papers in the possession or under the control of
the Collateral Agent relating to any or all Collateral and to make copies
thereof. Any such activity will be at the cost and expense of the Secured Party
requesting such access, except that following the occurrence of a Default, all
reasonable out-of-pocket costs and expenses associated with the exercise by a
Secured Party of its rights under this Paragraph 11 shall be promptly paid by
the Company upon demand of the Credit Agent.

      12. Representations and Warranties. The Company hereby represents and
warrants that: (a) the Company is the sole owner of the Collateral (or, in the
case of after-acquired Collateral, at the time the Company acquires rights in
the Collateral, will be the sole owner thereof), subject only to the rights of
Approved Investors under the Approved Investor Commitments; (b) except for
security interests in favor of the Collateral Agent for the benefit of the
Secured Parties hereunder, no Person has (or, in the case of after-acquired
Collateral, at the time the Company acquires rights therein, will have) any
right, title, claim or interest in, against or to the Collateral and, in any
event, so long as the Collateral Agent complies with the procedures relating to
possession of Collateral set forth in this Security Agreement, the Collateral
Agent shall have a perfected, first priority security interest therein for the
benefit of the Secured Parties; (c) no consent of any Person is required that
has not been obtained for the granting of the security interests provided for
herein, nor will any consent be required for the Collateral Agent to exercise
its rights under this Security Agreement in accordance with the terms of this
Security Agreement; (d) to the best of the Company's knowledge, all information
heretofore, herein or hereafter supplied to the Collateral Agent or to any
Lender by or on behalf of the Company with respect to the Collateral is or will
be accurate and complete; (e) the Approved Investor Commitments covering such
Collateral may be collaterally assigned to the Collateral Agent as described
herein; and (f) each Mortgage Loan and Security shall be, at all dates included
in the computation of the value of the Borrowing Bases, Eligible Collateral.

      13. Covenants of the Company. The Company hereby agrees: (a) to procure,
execute and deliver from time to time any endorsements, assignments, financing
statements and other writings reasonably deemed necessary or appropriate by the
Collateral Agent or the Credit Agent to perfect, maintain and protect the
Collateral Agent's or Credit Agent's security interest hereunder and the
priority thereof and to deliver promptly to the Collateral Agent or Credit Agent
all originals of any Collateral or proceeds thereof consisting of chattel paper
or instruments; (b) not to surrender or lose possession of

                                     - 11 -

<PAGE>

(other than to the Collateral Agent), sell, encumber, or otherwise dispose of or
transfer, any Collateral or right or interest therein other than shipment of
Mortgage Loans and Securities under Approved Investor Commitments and as
otherwise permitted under Paragraph 7 above and as otherwise permitted by the
Credit Agreement; (c) except as otherwise contemplated in any Custodial
Agreement, not to grant to any Federal Agency or Approved Investor any other
security interest in any Collateral, or otherwise acknowledge the creation of
any ownership rights of any Federal Agency or Approved Investor with respect to
any Collateral unless and until the Credit Agent has received the proceeds of
such Collateral as described herein; (d) at all times to account fully for and
promptly to deliver to the Collateral Agent or the Credit Agent, in the form
received, all Collateral or proceeds thereof received, endorsed to the
Collateral Agent or Credit Agent or in blank as appropriate and accompanied by
such assignments and powers, duly executed, as the Collateral Agent or the
Credit Agent shall reasonably request, and until so delivered all Collateral and
proceeds thereof shall be held in trust for the Collateral Agent or Credit Agent
for the benefit of the Secured Parties, separate from all other property of the
Company and identified as the property of the Collateral Agent for the benefit
of the Secured Parties; (e) to keep accurate and complete records of the
Collateral and at any reasonable time and at the Company's expense, upon demand
by the Collateral Agent or the Credit Agent, to exhibit to and allow inspection
of the Collateral and the records, reports and information concerning the
Collateral by the Collateral Agent or Credit Agent (or Persons designated by the
Collateral Agent or Credit Agent); (f) to keep the records concerning the
Collateral at the location(s) set forth in Paragraph 25 below and not to remove
the records from such location(s) without the prior written consent of the
Collateral Agent and the Credit Agent; (g) not to materially modify, compromise,
extend, rescind or cancel any deed of trust, mortgage, note or other document,
instrument or agreement connected with any Mortgage Loan pledged under this
Security Agreement or any document relating thereto or connected therewith or
consent to a postponement of strict compliance on the part of any party thereto
with any term or provision thereof in any material respect (except to the extent
(i) any such action is permissible in accordance with Federal Agency rules and
regulations, (ii) the ability to sell any affected Mortgage Loans to an Approved
Investor is not thereby diminished, and (iii) the value of such Collateral is
not thereby diminished); (h) to keep the Collateral insured against loss,
damage, theft, and other risks customarily covered by insurance, and such other
risks as the Collateral Agent or the Credit Agent may reasonably request; (i) to
do all acts that a prudent investor would deem necessary or desirable to
maintain, preserve and protect the Collateral; (j) not knowingly to use or
permit any Collateral to be used unlawfully or in violation of any provision of
this Security Agreement, the Credit Agreement or any applicable statute,
regulation or ordinance or any policy of insurance covering the Collateral; (k)
to pay (or require to be paid) prior to their becoming delinquent all taxes,
assessments, insurance premiums, charges, encumbrances and liens now or
hereafter imposed upon or affecting any Collateral except as otherwise permitted
in the Credit Agreement; (l) to notify the Collateral Agent and the Credit Agent
before any such change shall occur of any change in the Company's name, identity
or structure through merger, consolidation or otherwise; (m) to appear in and
defend, at the Company's cost and expense, any action or proceeding which may
affect its title to or the Collateral Agent's interest for the benefit of the
Secured Parties in the Collateral; and (n) to comply in all material respects
with all laws, regulations and ordinances relating to the possession, operation,
maintenance and control of the Collateral. Notwithstanding the foregoing, (1)
the requirements of clauses (g), (k) and (m) shall not apply to any Collateral
which is not required to be included in the computation of the value of any of
the Borrowing Bases in order for the Company to be in compliance with the
requirements of the Credit Agreement unless failure to comply with the
requirements of said subparagraphs would have an adverse effect on the
Collateral which is included in such computation, and (2) the failure of the
Company to comply with its obligations under this Paragraph 13 with respect to
any Pledged Item shall cause such Pledged Item to cease to qualify as Eligible
Collateral.

                                     - 12 -

      14. Collection of Collateral Payments.

            (a) The Company shall, at its sole cost and expense, use its best
efforts to obtain payment, when due and payable, of all sums due or to become
due with respect to any Collateral ("Collateral Payments" or a "Collateral
Payment"), consistent with all requirements of law and contractual obligations
binding upon the Company. Upon the request of the Credit Agent while a Default
exists, the Company will notify and direct any party who is or might become
obligated to make any Collateral Payment, to make payment thereof to the Credit
Agent at such address as the Credit Agent may designate. The Company will
reimburse the Credit Agent promptly upon demand for all out-of-pocket costs and
expenses, including reasonable attorneys' fees and litigation expenses, incurred
by the Credit Agent in seeking to collect any Collateral Payment.

            (b) Following the occurrence of a Default, upon the request of the
Credit Agent the Company will transmit and deliver to the Credit Agent,
forthwith upon receipt and in the form received, all cash, checks, drafts and
other instruments for the payment of money (properly endorsed where required so
that such items may be collected by the Credit Agent) which may be received by
the Company at any time as payment on account of any Credit Payment and if such
request shall be made, until delivery to the Credit Agent, such items will be
held in trust for the Credit Agent for the benefit of the Secured Parties and
will not be commingled by the Company with any of its other funds or property.
Thereafter, the Credit Agent is hereby authorized and empowered to endorse the
name of the Company on any check, draft or other instrument for the payment of
money received by the Credit Agent on account of any Collateral Payment if the
Credit Agent believes such endorsement is necessary or desirable for purposes of
collection.

            (c) The Company hereby agrees to indemnify, defend and save harmless
the Collateral Agent and the Credit Agent and their respective agents, officers,
employees and representatives from and against all reasonable liabilities and
expenses on account of any adverse claim asserted against the Collateral Agent
or the Credit Agent relating to any moneys received by the Collateral Agent or
the Credit Agent on account of any Collateral Payment (other than as a direct
result of the gross negligence or willful misconduct of the Collateral Agent or
the Credit Agent) and such obligation of the Company shall continue in effect
after and notwithstanding the discharge of the Secured Obligations and/or the
release of the security interest granted in Paragraph 3 above.

      15. Authorized Action by Collateral Agent. The Company hereby irrevocably
appoints the Collateral Agent as its attorney-in-fact to do (but the Collateral
Agent shall not be obligated to and shall incur no liability to the Company or
any third party for failure so to do) from time to time while a Default exists,
at the written request and direction of the Required Lenders, any act which the
Company is obligated by this Security Agreement to do, and to exercise such
rights and powers as the Company might exercise with respect to the Collateral,
including, without limitation, the right to (a) collect by legal proceedings or
otherwise and endorse, receive and receipt for all dividends, interest,
payments, proceeds and other sums and property now or hereafter payable on or on
account of the Collateral; (b) insure, process, service and preserve the
Collateral; (c) transfer the Collateral to the Collateral Agent's own or its
nominee's name; and (d) make any compromise or settlement, and take any other
action it deems advisable with respect to the Collateral. Notwithstanding
anything contained herein, in no event shall the Collateral Agent be required to
make any presentment, demand or protest, or give any notice, and the Collateral
Agent need not take any action to preserve any rights against any prior party or
any other person in connection with the Secured Obligations or with respect to
the Collateral.

      16. Default and Remedies.

                                     - 13 -

<PAGE>

            (a) While a Default exists, the Collateral Agent shall at the
written request and direction of the Credit Agent on behalf of the Required
Lenders, without notice to or demand upon the Company: (i) foreclose or
otherwise enforce the Collateral Agent's security interest for the benefit of
the Secured Parties in the Collateral in any manner permitted by law or provided
for hereunder; (ii) sell or otherwise dispose of the Collateral or any part
thereof at one or more public or private sales or at any broker's board or on
any securities exchange, whether or not such Collateral is present at the place
of sale, for cash or credit or future delivery (provided that the Required
Lenders have approved the terms of any sale on credit or for future delivery)
and without assumption of any credit risk, on such terms and in such manner as
the Collateral Agent may determine; (iii) require the Company to assemble the
Collateral and/or books and records relating thereto and make such available to
the Collateral Agent at a place to be designated by the Collateral Agent; (iv)
enter into property where any Collateral or books and records relating thereto
are located and take possession thereof with or without judicial process; and
(v) prior to the disposition of the Collateral, prepare it for disposition in
any manner and to the extent the Collateral Agent deems appropriate. Whether or
not the Collateral Agent exercises any right given pursuant to this Paragraph
16, upon the occurrence of any Default, the Collateral Agent on behalf of the
Secured Parties shall have as to any Collateral all other rights and remedies
provided for herein and all rights and remedies of a secured party under the
Illinois Uniform Commercial Code and, in addition thereto and not in lieu
thereof, all other rights or remedies at law or in equity existing or conferred
upon the Collateral Agent on behalf of the Secured Parties by other
jurisdictions or other applicable law or given to the Collateral Agent on behalf
of the Secured Parties pursuant to any security agreement, other instrument or
agreement heretofore, now, or hereafter given as security for the Company's
obligations hereunder.

            (b) The Collateral Agent is authorized, at any such sale, if it
deems it advisable so to do, to restrict the prospective bidders or purchasers
to Persons who will represent and agree that they are purchasing for their own
account, for investment, and not with a view to the distribution or sale of any
of the Collateral. Upon any sale or other disposition pursuant to this Security
Agreement, the Collateral Agent shall have the right to deliver, assign and
transfer to the purchaser thereof the Collateral or portion thereof so sold or
disposed of and all proceeds thereof shall, as set forth in Paragraph 17 below,
be promptly transmitted to the Credit Agent for allocation to the Secured
Parties in accordance with the Credit Agreement. Each purchaser at any such sale
or other disposition shall hold the Collateral free from any claim or right of
whatever kind, including any equity or right of redemption of the Company, and
the Company specifically waives (to the extent permitted by law) all rights of
redemption, stay or appraisal which it has or may have under any rule of law or
statute now existing or hereafter adopted. The Collateral Agent shall give the
Company only such notice and shall publish such notice as may be required by the
Illinois Uniform Commercial Code or by other applicable law of the intention to
make any such public or private sale or sale at broker's board or on a
securities exchange. Any such public sale shall be held at such time or times
within the ordinary business hours and at such place or places permitted by the
Illinois Uniform Commercial Code. At any such sale the Collateral may be sold in
one lot as an entirety or in separate parcels, as the Collateral Agent may
determine. The Collateral Agent may adjourn any public or private sale or cause
the same to be adjourned from time to time by announcement at the time and place
fixed for the sale, and such sale may be made at any time or place to which the
same may be so adjourned. In case of any sale of all or any part of the
Collateral on credit or for future delivery (the terms of which shall be
approved by the Required Lenders), (i) the Collateral so sold may be retained by
the Collateral Agent until the selling price is paid by the purchaser thereof,
(ii) none of the Secured Parties shall incur any liability in case of the
failure of such purchaser to take up and pay for the Collateral so sold, and
(iii) in case of any such failure, such Collateral may again be sold as provided
herein. Nothing contained in this Security Agreement shall prohibit any Lenders
from purchasing the Collateral at such sale.

                                     - 14 -

<PAGE>

            (c) The Company hereby appoints the Collateral Agent as the
Company's attorney-in-fact, effective as of the date of any Unmatured Default
(and during the continuance thereof) for the purpose of taking all actions on
behalf of the Company contemplated or required under the terms of the
Acknowledgement Agreements with respect to Pledged Servicing and executing any
instruments which the Collateral Agent may deem necessary or advisable to
accomplish the purposes hereof, which appointment as attorney-in-fact is
irrevocable and coupled with an interest. Without limiting the generality of the
foregoing, the Collateral Agent shall have the right and power to receive,
endorse and collect all checks made payable to the order of the Company
representing any payment on account of the principal of or interest on any of
the Mortgage Loans covered by such Pledged Servicing or on account of the terms
of the Servicing Agreements governing such Pledged Servicing and to give full
discharge for the same. Furthermore, notwithstanding anything herein to the
contrary, with respect to any Collateral covered by an executed Acknowledgement
Agreement, the Collateral Agent is authorized to carry out and comply with, and
the Company approves and acknowledges, all requirements regarding such a sale
set forth therein or as may otherwise be imposed by the counterparty to such an
Acknowledgement Agreement and agrees that such a sale in accordance with the
requirements of an Acknowledgement Agreement is commercially reasonable.

      17. Disposition of Proceeds. "Net Proceeds" shall mean the proceeds
realized upon the sale or other disposition of any Collateral after deducting
therefrom the payment of the costs and expenses of such sale or disposition,
including (i) reasonable compensation to the Collateral Agent's and Credit
Agent's agents and counsel, and all expenses, liabilities and advances made or
incurred by any Secured Party acting on instructions of the Required Lenders,
and (ii) with respect to the Pledged Servicing, the payment of any amounts due
by the Company to FNMA or FHLMC, as the case may be, as a condition to the
transfer of the Company's interest in any such Servicing Agreements pursuant to
the terms of such Servicing Agreements, including without limitation all amounts
described in the Acknowledgement Agreements. All such costs and expenses shall
be deducted from the proceeds directly related thereto. The Collateral Agent
shall distribute the Net Proceeds to the Credit Agent for the benefit of the
Secured Parties.

      18. Waiver. No Secured Party shall incur any liability as a result of the
sale of the Collateral, or any part thereof, at any public or private sale. The
Company hereby waives any claims it may have against any Secured Party arising
by reason of the fact that the price at which the Collateral may have been sold
at such private sale was less than the price which might have been obtained at a
public sale or was less than the aggregate amount of the Secured Obligations
then outstanding.

      19. The Collateral Agent.

            (a) Collateral Agent's Fee. Compensation of the Collateral Agent for
its services hereunder and reimbursement for any expenses incurred by it in the
performance of its duties hereunder shall be paid by the Company pursuant to a
separate fee schedule previously delivered by the Collateral Agent to the
Company (the "Fee Schedule"). The Collateral Agent shall notify the Company of
all extraordinary fees, costs and expenses of the Collateral Agent directly
relating to the Collateral Agent's performance of this Security Agreement, and
such extraordinary fees, costs and expenses shall be paid promptly by the
Company or, if already paid by the Collateral Agent, the Company promptly shall
reimburse the Collateral Agent therefor. For the purposes of this provision,
extraordinary fees, costs and expenses shall include all fees, costs and
expenses incurred by the Collateral Agent in performance of this Security
Agreement which are not otherwise expressly covered by the Fee Schedule,
including, without limitation, expenses of legal counsel to the Collateral Agent
and the fees and expenses of the Collateral Agent undertaking any activity
described in Paragraphs 14, 15 and 16 above or procedures related to reviewing
of documents listed on Schedule B or in furnishing any additional reports and

                                     - 15 -

<PAGE>

information reasonably requested by the Credit Agent or any Lender pursuant to
clause (c) of Paragraph 8 above.

            (b) Actions by the Collateral Agent. The obligations of the
Collateral Agent hereunder are only those expressly set forth herein. The
Collateral Agent shall be entitled to (but shall not be obligated to) take or
refrain from taking any discretionary powers or actions under this Security
Agreement or any other Credit Document unless and until the Collateral Agent
shall have received the written direction to take or refrain from taking such
action from the Required Lenders (or all of the Lenders with respect to actions
which require unanimous approval of the Lenders). The Collateral Agent shall not
be required to take any action hereunder if it shall reasonably determine that
by so doing it may incur criminal or civil liability.

            (c) Consultation with Experts. The Collateral Agent may consult with
legal counsel (who may be counsel for the Company), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts; provided, however, that the
Collateral Agent shall consult counsel for the Company only with regard to
information about the Company and shall not request legal advice from such
counsel.

            (d) Liability of Collateral Agent.

               (1) Neither the Collateral Agent, its Affiliates nor any of its
   directors, officers, agents, or employees shall be liable for any action
   taken or not taken by it in connection herewith (i) with the consent or at
   the request of the Required Lenders or (ii) in the absence of its own gross
   negligence or willful misconduct. Furthermore, in no event shall the
   Collateral Agent or its Affiliates, directors, officers, agents, and
   employees be held liable for any special, indirect, punitive or consequential
   damages resulting from any action taken or omitted to be taken by it or them
   hereunder or in connection herewith even if advised of the possibility of
   such damages.

               (2) The Collateral Agent shall not incur any liability by acting
   in reliance upon any notice, consent, certificate, statement, or other
   writing (which may be a bank wire, telex or similar writing) or telephone
   communication believed by it to be genuine or, in the case of a writing, to
   be signed by the proper party or parties.

               (3) Except as provided in Paragraph 5 above, the Collateral Agent
   shall not be under a duty to examine into or pass upon the validity,
   effectiveness, genuineness or value of the Collateral or any other instrument
   or document furnished pursuant thereto or thereunder, and Collateral Agent
   shall be entitled to assume that the same are valid, effective and genuine in
   what they purport to be.

            (e) Indemnification. The Company agrees to indemnify and hold the
Collateral Agent and its directors, officers, agents, and employees harmless
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses, or disbursements of any kind or
nature whatsoever, including reasonable attorneys' fees, that may be imposed on,
incurred by, or asserted against the Collateral Agent or its affiliates,
directors, officers, agents, or employees, in anyway relating to or arising out
of this Agreement or any action taken or not taken by the Collateral Agent or
its permitted successors and assigns under this Agreement unless such
liabilities, obligations, losses, damages, penalties, actions, judgments suits,
costs, expenses, or disbursements were imposed on, incurred by or asserted
against the Collateral Agent because of the breach by the Collateral Agent of
its

                                     - 16 -

<PAGE>

obligations under this Agreement, which breach was caused by the gross
negligence, lack of good faith, or willful misconduct on the part of the
Collateral Agent or any of its affiliates, directors, officers, agents, or
employees. The foregoing indemnification shall survive any termination or
expiration of this Agreement or the resignation or removal of the Collateral
Agent. Subject to the limitations set forth below, the Lenders shall indemnify
the Collateral Agent (to the extent not reimbursed by the Company) against any
cost, expense (including reasonable counsel fees and disbursements), claim,
demand, action, loss or liability (except such as result from the Collateral
Agent's gross negligence or willful misconduct) that the Collateral Agent may
suffer or incur in connection with this Security Agreement or any action taken
or omitted by the Collateral Agent hereunder (the "Indemnified Amount"). Any
Indemnified Amount due to the Collateral Agent shall be paid by the Lenders pro
rata in accordance with their respective shares of the Secured Obligations
outstanding at the time the Collateral Agent incurred such liability. The
provisions of this Paragraph 19(e) shall survive the termination of this
Security Agreement.

            (f) Knowledge of Defaults. The Collateral Agent shall not be deemed
to have knowledge or notice of the occurrence of a Default unless the Collateral
Agent has received notice from a Secured Party or the Company referring to a
Credit Agreement or this Security Agreement describing such Default and stating
that such notice is a "Notice of Default." Following receipt of a Notice of
Default, the Collateral Agent shall assume that the Default is continuing until
the Collateral Agent receives written information to the contrary from the
Credit Agent.

            (g) Reports. The Collateral Agent may, at its option with the
approval of the Company and the Credit Agent, alter the format of any report
required hereunder, provided such modified report contains the same information
previously furnished in the unmodified report.

            (h) Other Transactions with Company. The Collateral Agent and its
Affiliates may accept deposits from, lend money to, and generally engage in any
kind of business with, the Company or any Subsidiary or Affiliate of the Company
as if it were not the Collateral Agent hereunder.

            (i) Resignation/Removal. The Collateral Agent may resign at any time
by giving 90 days prior written notice thereof to the Lenders and the Company.
The Collateral Agent also agrees to resign within 90 days after written notice
by the Company requesting the resignation of the Collateral Agent provided that
no Default has occurred and is continuing at the time of such request. In
addition, in the event the Collateral Agent fails to perform its obligations
under this Security Agreement in any material manner and fails to correct its
performance within 30 days of receipt of written notice of such failure given by
the Credit Agent at the request of not less than the Required Lenders, then the
Collateral Agent may be removed upon 30 days written notice given by the Credit
Agent at the direction of not less than the Required Lenders. Upon any such
resignation or removal: (i) so long as there has not occurred and is continuing
a Default, the Company shall appoint (which appointment shall be subject to the
approval of the Required Lenders, such approval not to be unreasonably withheld
or delayed), a successor agent for such Collateral Agent, and (ii) following the
occurrence and during the continuance of a Default, the Required Lenders shall
appoint a successor agent for such Collateral Agent who is in the business of
acting as a collateral agent for mortgage warehouse lenders as a part of its
regular business. Following the appointment and acceptance of a successor
Collateral Agent, the Collateral shall be transferred to the new Collateral
Agent within 30 days after such acceptance. If the Company and/or the Required
Lenders, as applicable, are unable to agree on the appointment of a successor
agent by a date 10 days prior to the effective date of such resignation or
removal, the retiring Collateral Agent shall appoint a successor Collateral
Agent who is in the business of acting as a collateral agent for mortgage
warehouse lenders as a part of its regular business. After the appointment of a
successor Collateral Agent and the successor's acceptance of such appointment,
that successor Collateral Agent

                                     - 17 -

<PAGE>

shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Collateral Agent, and the retiring
Collateral Agent shall be discharged from its duties and obligations under this
Security Agreement; provided, however, that the retiring Collateral Agent shall
not be discharged from any liability as a result of its or its directors',
officers', agents' or employees' gross negligence or willful misconduct in
connection with the performance of its duties and obligations under this
Security Agreement prior to the effective date of its resignation or removal.
Notwithstanding the foregoing, the Collateral Agent shall continue to hold the
Pledged Items and the security interest created hereunder for the benefit of the
Secured Parties until such Pledged Items and security interest have been
effectively transferred to the successor agent. After the resignation or removal
of any Collateral Agent hereunder, the provisions of this Security Agreement
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was the Collateral Agent under this Security Agreement.

            (j) Representations and Warranties. The Collateral Agent hereby
represents and warrants:

                  (1) The Collateral Agent is a national banking association
      validly existing, in good standing and authorized to exercise its powers,
      rights and privileges and is qualified to do business in all jurisdictions
      where necessary, and has all requisite power and authority to perform all
      of its obligations under this Security Agreement;

                  (2) The execution, delivery and performance by the Collateral
      Agent of this Security Agreement and all documents required hereby to be
      executed by the Collateral Agent have been duly authorized by all
      necessary corporate action and do not and will not violate any existing
      provision of any law, rule, regulation, order, writ, judgment, injunction,
      decree, determination or award currently in effect having applicability to
      the Collateral Agent; and

                  (3) This Security Agreement and all documents required hereby
      to be executed by the Collateral Agent have been duly executed and
      delivered by the Collateral Agent.

            (k) Tax Returns. The Collateral Agent shall not be responsible for
preparing or filing any reports or returns relating to federal, state or local
income taxes with respect to this Security Agreement, other than for the
Collateral Agent's compensation or for reimbursement of expenses.

            (l) Deemed Notification. Any other provision of this Security
Agreement to the contrary notwithstanding, the Collateral Agent shall have no
notice, and shall not be bound by any of the terms and conditions of any other
document or agreement executed or delivered in connection with, or intended to
control any part of, the transactions anticipated by or referred to in this
Security Agreement unless the Collateral Agent is a signatory party to that
document or agreement. Notwithstanding the foregoing sentence, the Collateral
Agent shall be deemed to have notice of the terms and conditions (including
without limitation definitions not otherwise set forth in full in this Security
Agreement) of other documents and agreements executed or delivered in connection
with, or intended to control any part of, the transactions anticipated by or
referred to in this Security Agreement, to the extent such terms and provisions
are referenced, or are incorporated by reference, into this Security Agreement
only as long as the Company or the Credit Agent shall have provided a copy of
any such document or agreement to the Collateral Agent.

            (m) Business Qualification. Nothing in this Security Agreement shall
be deemed to impose on the Collateral Agent any duty to qualify to do business
in any jurisdiction, other than (i) any jurisdiction where any Collateral
documents are or may be held by the Collateral Agent from time to

                                     - 18 -

<PAGE>

time hereunder, and (ii) any jurisdiction where its ownership of property or
conduct of business requires such qualification and where failure to qualify
could have a material adverse effect on the Collateral Agent or its property or
business or on the ability of the Collateral Agent to perform it duties
hereunder.

            (n) Verification of Signatures. Under no circumstances shall the
Collateral Agent be obligated to verify the authenticity of any signature on any
of the documents received or examined by it in connection with this Security
Agreement or the authority or capacity of any person to execute or issue such
document.

            (o) Verification of Payment. The Collateral Agent shall have no duty
to ascertain whether or not any cash amount or payment has been received by the
Company, the Credit Agent or any third person.

            (p) Collateral Agent Expenditures. No provision of this Security
Agreement shall require the Collateral Agent to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights and powers, if, in its sole
judgment, it shall believe that repayment of such funds or adequate indemnity
against such risk or liability is not assured to it.

            (q) Merger or Consolidation. Any entity into which the Collateral
Agent may be merged or converted or with which it may be consolidated, or any
entity resulting from any merger, conversion or consolidation to which the
Collateral Agent shall be a party, or any entity succeeding to the business of
the Collateral Agent, shall be the successor of the Collateral Agent hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding.

            (r) Affiliates. The Company and the Credit Agent agree that the
Collateral Agent may execute any of its duties under this Security Agreement
through any of its agents, attorneys-in-fact, or Affiliates. Any such agent,
attorney-in-fact, or Affiliate (and such Affiliate's directors, officers, agents
and employees) which performs duties in connection with this Security Agreement
shall be entitled to the same benefits of the indemnification, waiver and other
protective provisions to which the Collateral Agent is entitled under this
Security Agreement. In particular, to the extent the Collateral Agent is
directed to or may exercise any rights or remedies with respect to this Security
Agreement or any other Credit Document, the Collateral Agent may appoint agents
to exercise any such rights or remedies on behalf of the Collateral Agent. The
Collateral Agent may also assign its rights and obligations under this
Agreement, in whole or in part, to any Affiliate; however, Collateral Agent
agrees to notify Company and Credit Agent of any such assignment.

            (s) Force Majeure. The Collateral Agent shall not be responsible for
delays or failures in performance resulting from acts beyond its control. Such
acts shall include, but not be limited to, acts of God, strikes, lockouts,
riots, acts or war or terrorism, epidemics, nationalization, expropriation,
currency restrictions, governmental regulations superimposed after the fact,
fire, communication line failures, computer viruses, power failures, earthquakes
or other disasters.

      20. Confidentiality. The Collateral Agent agrees to take normal and
reasonable precautions and exercise due care to maintain the confidentiality of
all non-public information provided to it by the Company or by any other party
on the Company's behalf in connection with this Security Agreement or the other
Credit Documents and agrees and undertakes that neither it nor any of its
Affiliates shall disclose any such information for any purpose or in any manner
other than pursuant to the terms contemplated by this Security Agreement or the
other Credit Documents. The Collateral Agent may

                                     - 19 -

<PAGE>

disclose such information (1) to any Secured Party, (2) at the request of any
regulatory authority or in connection with an examination of the Collateral
Agent or any of its Affiliates by any such authority, (3) pursuant to subpoena
or other court process, (4) when required to do so in accordance with the
provisions of any applicable law, (5) at the express direction of any other
governmental authority of any State of the United States of America or of any
other jurisdiction in which the Collateral Agent or any of its Affiliates
conducts its business, (6) to the Collateral Agent's or any of its Affiliates'
independent auditors, attorneys and other professional advisors, (7) if such
information has become public other than through disclosure by the Collateral
Agent or any of its Affiliates or any Lender, and (8) in connection with any
litigation involving the Collateral Agent or any of its Affiliates. The
Collateral Agent shall give the Company prior written notice of any disclosure
pursuant to clause (2), (3), (4) or (5) of the preceding sentence unless the
Collateral Agent is prohibited from doing so by the party requesting such
information. Notwithstanding the foregoing, the Company authorizes the
Collateral Agent to disclose to any lending institution proposed by the Company
to become a Lender under the Credit Agreement or any prospective or actual
Participants such financial and other information in its possession (i) which
has been delivered to the Collateral Agent pursuant to the Credit Documents or
which has been delivered to the Collateral Agent by the Company prior to
entering into the Credit Documents or (ii) which is reasonably necessary to
effectuate the purposes of the Credit Agreement and this Security Agreement,
provided that unless otherwise agreed by the Company, such lending institution
or Participant shall agree in writing to keep such information confidential to
the same extent required of the Collateral Agent hereunder.

      21. Voting of Debtholders. In all cases in which this Security Agreement
requires the consent, approval or direction of the Required Lenders or all of
the Lenders with respect to any action, the Credit Agent shall be responsible
for determining whether the Lenders have given such consent, approval or
direction and shall notify the Collateral Agent thereof in writing. The
Collateral Agent shall be entitled to rely without independent verification upon
the information supplied by the Credit Agent with respect to any consent,
approval or direction of the Required Lenders (or all of the Lenders with
respect to actions which require unanimous approval of the Lenders).

      22. Binding Upon Successors. All rights of the Collateral Agent and the
Secured Parties under this Security Agreement shall inure to the benefit of the
Collateral Agent and the Secured Parties and their successors and assigns. This
Security Agreement shall not be assignable by the Company without the consent of
all Lenders.

      23. Entire Agreement; Severability. This Security Agreement contains the
entire security agreement and collateral agency agreement with respect to the
Collateral among the Secured Parties and the Company and supersedes all prior
written or oral agreements and understandings relating thereto. All waivers by
the Company provided for in this Security Agreement have been specifically
negotiated by the parties with full cognizance and understanding of their
rights. If any of the provisions of this Security Agreement shall be held
invalid or unenforceable, this Security Agreement shall be construed as if not
containing such provisions, and the rights and obligations of the parties hereto
shall be construed and enforced accordingly.

      24. Choice of Law. This Security Agreement shall be construed in
accordance with and governed by the laws of the State of Illinois. Where
applicable and except as otherwise defined herein, terms used herein shall have
the meanings given them in the Illinois Uniform Commercial Code.

      25. Place of Business; Records. The Company represents and warrants that
its principal place of business and chief executive office is at the address set
forth beneath its signature below, and that its books and records concerning the
Collateral are kept at its principal place of business and chief

                                     - 20 -

<PAGE>

executive office. The Company shall not change its principal place of business
and chief executive office without 30 days' prior written notice to the Credit
Agent and the Collateral Agent.

      26. Notice. Except where instructions or notices are expressly authorized
elsewhere in this Security Agreement to be given by telephone or by other means
of transmission, all instructions, notices and other communications to be given
to any party hereto shall be in writing and shall be personally delivered or
sent by certified mail, postage prepaid, private delivery service or by
facsimile, and shall be deemed to be given for purposes of this Security
Agreement on the day (or at the time of day, if applicable) when actually
received by the intended party at its address or facsimile or telephone number
as set forth following its signature below (or as such party may specify to the
other parties in writing).

      27. Waiver of Jury Trial.

          EACH PARTY TO THIS SECURITY AGREEMENT HEREBY WAIVES TRIAL BY JURY IN
ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER
SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO,
OR CONNECTED WITH ANY CREDIT DOCUMENT OR THE RELATIONSHIP ESTABLISHED
THEREUNDER.

      assignment containing the specific information regarding the related
      mortgage or deed of trust needed for recordation for any mortgage or deed
      of trust held by MERS so long as the Company has delivered to and
      maintains with the Collateral Agent (A) a supply of not less than 3,500
      executed, non-specific assignments which have blanks for the insertion of
      such specific information regarding the assigned mortgage or deed of trust
      (or any greater amount of such assignments that the Collateral Agent may
      require by written notice to the Company if the volume of the Company's
      mortgages registered with MERS materially increases) and (B) an
      irrevocable power-of-attorney executed by the Company (pursuant to
      appropriate corporate resolution of MERS) authorizing the Collateral Agent
      to insert all such specific information into such assignments on behalf of
      the Company.

                              REQUIRED REVIEW STEPS

1.    All submitted documents, are consistent with the related Collateral
      Transmittal as to borrower name, loan face amount, loan type and the
      Company's loan number.

2.    The note and mortgage/deed of trust each bears an original signature or
      signatures which appear to be those of the person or persons named as the
      maker and mortgagor/trustor, or, in the case of a certified copy of the
      mortgage/deed of trust, such copy bears what appears to be a reproduction
      of such signature or signatures.

3.    Except for (a) the endorsement to the Company of the note in the event
      such loan was purchased by the Company and (b) the endorsement in blank of
      the note by an authorized signatory of the Company, neither the note, the
      mortgage/deed of trust, nor the assignment(s) of the mortgage/deed of
      trust contain any irregular writings which appear on their face to affect
      the validity of any such endorsement or to restrict the enforceability of
      the document on which they appear.

4.    The note is endorsed in blank by an authorized signatory of the Company.

5.    The assignment of the mortgage/deed of trust (or, if such mortgage/deed of
      trust is covered by a supply of non-specific assignments as permitted
      under Schedule A to the Security Agreement, each such non-specific
      assignment) bears an original signature of an authorized officer of the
      Company, based on the current list of such officers supplied by the
      Company, or an original signature of an officer of the Company authorized
      by MERS, as nominee of the Company, to sign on behalf of MERS, based on
      the corporate resolution of MERS which appointed such officers of the
      Company for such purpose (a copy of such resolution having been provided
      by the Company).

6.    Such other review steps as the Collateral Agent, in its sole discretion,
      deems appropriate.

       Re: Pulte Mortgage LLC

Ladies and Gentlemen:

      The undersigned, LaSalle Bank National Association (the "Collateral
Agent") acts in the capacity as Collateral Agent pursuant to: (1) that certain
Sixth Amended and Restated Revolving Credit Agreement dated as of May ___, 2006
(as amended from time to time, the "Credit Agreement", and as capitalized terms
not otherwise defined herein are used with the same meaning as in the Credit
Agreement) by and among PULTE MORTGAGE LLC (the "Company"), the lenders
participating therein (collectively, the "Lenders"), and JPMORGAN CHASE BANK,
N.A., as agent for the Lenders (the "Credit Agent"), and (2) that certain Fifth
Amended and Restated Security and Collateral Agency Agreement (the "Security
Agreement") dated concurrently therewith among the Collateral Agent, the
Company, and the Credit Agent.

      The Collateral Agent represents and confirms that it has the power and
authority under the Credit Agreement and the Security Agreement to execute this
Custodial Agreement. The Collateral Agent may execute any of its duties
hereunder by or through agents or attorneys-in-fact of whose appointment you
have been notified in writing.

      The Collateral Agent hereby appoints you and you hereby accept appointment
to act as agent, custodian and bailee for the benefit of the Secured Parties (as
defined in the Security Agreement) (in such capacity, the "Approved MBS
Custodian"). In such capacity, you agree to accept delivery only on a free basis
of certain mortgage-backed securities delivered to you from time to time
identified in a letter in the form attached hereto as Exhibit A (all such
mortgage-backed securities delivered to you and so identified being referred to
herein as "Subject Securities"). This Custodial Agreement governs your rights
and responsibilities as Approved MBS Custodian with respect to all Subject
Securities.

      The Collateral Agent hereby directs you, as Approved MBS Custodian, to
hold or dispose of Subject Securities deposited with you only in accordance with
the instructions of a person described as an "Authorized Collateral Agent
Representative" on a schedule from time to time delivered to you by the
Collateral Agent (the initial list of such persons being attached hereto as
Schedule I) or otherwise as expressly permitted hereunder, including without
limitation the Company's right to direct the sale or disposition of the Subject
Securities as described in the following paragraph. You are authorized, directed
and instructed to act upon all instructions from persons reasonably believed by
you to be

                                     - 38 -

<PAGE>

genuine and authorized. Any instruction given hereunder may, in your discretion,
be by telegraph, cable, facsimile or electronic communication which is received
by you.

      All Subject Securities are to be held by you in a custodial account
(Account No. __________) maintained with you (the "MBS Custodial Account").
Unless and until you have received written notice to the contrary from the
Collateral Agent at the direction of the Required Lenders (which notice may be
by facsimile transmission) following a Default, you may from time to time
deliver Subject Securities at the direction of the Company to, but only to,
Approved Investors (as listed on a schedule of "Approved Investors" delivered to
you from time to time by an Authorized Collateral Agent Representative) against
payment of the purchase price therefor. Notwithstanding the preceding sentence,
even after your receipt of notice from the Collateral Agent that a Default
exists, you may deliver Subject Securities at the direction of the Company, but
only to Approved Investors pursuant to then-existing Approved Investor
Commitments. The proceeds of the sale or other disposition of all Subject
Securities are to be held by you in an account (Account No. __________)
maintained with you (the "Custodian Settlement Account") and transferred by the
end of each Business Day an account maintained in the Company's name at JPMorgan
Chase Bank, N.A. and designated by the Credit Agent from time to time by notice
to you (the "Designated Account"). The initial Designated Account is as follows:

                          JPMorgan Chase Bank, N.A.
                          ABA 021-000-21

      By executing this Custodial Agreement the Company confirms and the
Collateral Agent and the Company notify you that the Company has assigned and
granted to the Collateral Agent and/or the Credit Agent a security interest in
and lien upon all now existing and hereafter arising right, title and interest
of the Company in the MBS Custodial Account, the Custodian Settlement Account
and the Designated Account and in any and all investments and proceeds at any
time held therein.

      You shall be under no duty to take or omit to take any action with respect
to Subject Securities, except as specifically set forth in this Agreement and
the Operating Instructions attached hereto as Exhibit B, unless specifically
otherwise directed by the Collateral Agent and agreed to by you in writing. In
the event that you shall be uncertain as to your duties or rights hereunder, you
shall be entitled to refrain from taking any action until you shall be directed
otherwise by an order of a court of competent jurisdiction. In case you should
agree to our request and on our behalf to appear in, prosecute or defend any
legal or equitable proceeding either in your own name or in the name of your
nominee, you shall first be indemnified to your satisfaction (other than against
your gross negligence and willful misconduct).

      By accepting delivery of any Subject Security, you shall be deemed to have
agreed to hold such Subject Security as Approved MBS Custodian hereunder, free
and clear of all liens, claims, interests and rights of offset in your favor or
in favor of persons claiming through you. You may accept certified checks in
payment for Subject Securities delivered on the Company's instruction and you
shall not be responsible for the risks of collectability of any such checks. YOU
ARE HEREBY IRREVOCABLY INSTRUCTED BY THE COMPANY AND THE COLLATERAL AGENT THAT
ALL PROCEEDS RECEIVED FROM THE SALE OR OTHER DISPOSITION OF SUBJECT SECURITIES,
UNTIL OTHERWISE NOTIFIED IN WRITING BY THE CREDIT AGENT, SHALL BE WIRED TO THE
DESIGNATED ACCOUNT AS PROVIDED ABOVE.

                                     - 39 -

      You will provide to the Collateral Agent and the Credit Agent on a daily
basis at or before 9:30 a.m. (Chicago time) a report of the prior day's activity
with respect to the MBS Custodial Account and the Custodian Settlement Account.

      You shall not be liable or accountable for any act or omission of brokers,
dealers or agents in connection with this Custodial Agreement. In carrying out
your duties hereunder, you may use such methods or agencies as you determine in
your sole discretion, including your own facilities.

      You shall maintain regular business records documenting all instructions
transmitted to you through any authorized means and any response by you. You are
authorized to electronically record any telephone communications with the
Company or the Collateral Agent or Credit Agent arising out of this Custodial
Agreement. Your records shall be determinative of the form, content and time of
all the Company's and Collateral Agent's and Credit Agent's instructions and any
response from you. The record of each instruction and any response thereto shall
be retained by you for at least ninety (90) days following the date of the
instruction. Any claim against you for failure to properly follow an instruction
transmitted by the Company or the Collateral Agent or Credit Agent must be made
in writing and received by you within ninety (90) days after the date such
instruction was received by you.

      You shall give the Subject Securities that come into your possession under
this Custodial Agreement the same physical care and safeguards as are afforded
similar property owned by you; provided, however, your responsibility hereunder
is limited to losses occasioned directly by the gross negligence or willful
misconduct of your employees, to the extent of the market value of the Subject
Securities at the date of the discovery of such loss. With respect to any
Subject Securities which you deliver for us to a third party, and with respect
to such delivery, you shall be deemed no more than an "intermediary" as
referenced in Section 8-306(3) of the New York Uniform Commercial Code, and the
only warranty given by you shall be the warranty provided in said Section
8-306(3). In no event shall you be liable for any indirect, special or
consequential loss, even if you have been advised of the possibility of such
loss. You may, at your option, make arrangements for insuring yourselves against
loss from any cause, but you shall not be under any obligation to insure for our
benefit.

      None of the Subject Securities held in the MBS Custodial Account, the
funds held at any time in the Custodian Settlement Account, the Subject
Securities or any proceeds of the sale or other disposition thereof will be
subject to any right, charge, security interest, lien, encumbrance or claim of
any kind in your or your creditors' favor. Any claims for the payment of fees
with respect to the safe custody or administration of Subject Securities or for
compensation, expenses, commitments made by you upon instructions of the
Collateral Agent, or the Credit Agent, reimbursement of taxes incurred by you
for the account of the Collateral Agent or Credit Agent, any penalties incurred
by or levied or assessed against you resulting from the Collateral Agent's or
Credit Agent's improper or incorrect instructions, or other liabilities of the
Collateral Agent or Credit Agent to you, and for indemnity against any claim or
liability to which you are subjected by reason of any registration of Subject
Securities shall be enforceable solely against the Company and none of the
Collateral Agent, the Credit Agent or any Secured Party shall have any
responsibility therefor (except to the extent any of the foregoing are due to
the gross negligence or willful misconduct of the Collateral Agent, the Credit
Agent or any Secured Party, as applicable). The Collateral Agent and the Company
agree to make no claim against you except for any such claims or liabilities
arising, or claimed to have arisen, as a result of your gross negligence or
willful misconduct.

      The Operating Instructions attached hereto are hereby made part hereof and
any and all capitalized terms defined herein shall have the same meaning when
used therein.

                             OPERATING INSTRUCTIONS

      These Operating Instructions are attached to and made a part of the
Custodial Agreement between LaSalle Bank National Association and
___________________, dated as of _______________, 200_ (as amended from time to
time, the "Custodial Agreement"). Terms defined therein shall have their same
meanings when used herein.

      1. From time to time GNMA, FNMA and FHLMC Subject Securities will be
issued at the request of the Company and credited to your account with The
Federal Reserve Bank of New York ("FRBNY") (in the case of FNMA and FHLMC
Subject Securities) or your account with the Participants Trust Company ("PTC")
(in the case of GNMA Subject Securities) (in each case, to be held by you for
the account of the Collateral Agent) in accordance with the Code of Federal
Regulations (in the case of FNMA and FHLMC Subject Securities) or the rules of
PTC (in the case of GNMA Subject Securities). Upon your receipt of confirmation
that such Subject Securities have been deposited into your account with FRBNY
(in the case of FNMA and FHLMC Subject Securities) or your account with PTC (in
the case of GNMA Subject Securities), you shall promptly issue to the Collateral
Agent and the Company your confirmation that (1) you have received such
confirmation of the Fedwire (in the case of FNMA and FHLMC Subject Securities,
which confirmation will include the number of Subject Securities deposited into
your account with FRBNY) or from PTC (in the case of GNMA Subject Securities),
(2) you have made appropriate entries on your books reflecting the interests of
the Company as beneficial owner and the Collateral Agent as secured party with
respect to such Subject Securities, and (3) there are no security interests or
any rights or claims of any third party in such Subject Securities in your favor
or known to you which have priority over the security interest of the Collateral
Agent in such Subject Securities. You shall have no obligation to ensure or
verify that Securities identified in transmittal letters (in the form of Exhibit
A to the Custodial Agreement) are in fact credited to your account(s), but you
shall be obligated only to report your actual receipt of Subject Securities to
the Collateral Agent and the Company in accordance with the provision of this
Instruction 1.

      2. With respect to the delivery or transfer of Subject Securities which
you hold for the account of the Collateral Agent, you are hereby authorized to
act only upon instructions from the Collateral Agent or, to the extent permitted
by the Custodial Agreement, by the Company. Upon notification to you by the
Collateral Agent at the direction of the Required Lenders following a Default,
no third party, including without limitation the Company, may direct you to make
any delivery or transfer of such Subject Securities other than Subject
Securities to be delivered pursuant to then-existing Approved Investor
Commitments.

      3. The proceeds of redemptions, collections and other receipts, including
dividend and interest income, shall be credited to the Custodial Settlement
Account upon collection or payment.

      4. You are to notify the Collateral Agent and the Company upon receipt of
notice by you of any call for conversion, redemption, subscription rights or
similar proceeding affecting the Subject Securities held in the relevant account
(any of the foregoing being referred to herein as "Account Proceedings"), and
shall take such action in respect thereof as you may be directed in writing by
the Collateral Agent; provided, however, that you shall have no duty or
responsibility to notify the

                                     - 46 -

<PAGE>

Company or the Collateral Agent of any Account Proceedings which do not appear
in The Wall Street Journal (New York Edition), Financial Daily Called Bond
Service, The Kenney Services or official notifications from the Depository Trust
Company or such other publications which you may deem reasonable from time to
time. All solicitation fees payable to you as agent in connection with such
event will be retained by you unless specifically agreed to the contrary by you.

      5. You are authorized and empowered in the name and on behalf of the
Collateral Agent and the Company to execute any certificates of ownership or
other reports which you are or may hereafter be required to execute and furnish
under any regulation of the Internal Revenue Service, or other authority of the
United States, insofar as the same are required in connection with any property
which is now or may hereafter be in your possession by virtue of the Custodial
Agreement and these Operating Instructions, claiming no exemptions on behalf of
the Collateral Agent or the Company. In the preparation of such reports, the
status of the Collateral Agent is to be described as a bank, trust company or
financial institution, as the case may be, domiciled in the United States. The
Collateral Agent agrees to notify you immediately in writing of any change in
such status.

      6. All mail communications which are to be furnished or forwarded
hereunder to the Collateral Agent or the Company shall be addressed to such
party at the last address on your records, provided that in case you in your
sole discretion shall determine that an emergency exists, you may use such other
means of communication as you shall deem advisable.

      7. You are under no duty to supervise, recommend or advise the Collateral
Agent relative to the investment, purchase, sale, retention or other disposition
of any property held hereunder unless specifically provided for by the Custodial
Agreement.

      8. With respect to any direction to receive securities in transactions not
placed through you, you shall have no duty or responsibility to advise the
Company of non-receipt, or to take any steps to obtain delivery of securities
from any brokers or dealers. All dealer concessions made to you will be retained
by you unless specifically agreed to the contrary by you.

      9. Notwithstanding anything herein to the contrary, unless instructions
are received from the Collateral Agent, specifying a different destination than
the address listed on your records for the Collateral Agent, within ten (10)
days of the receipt of any termination notice, you shall have the right to
transfer all securities and other property held by you or any depositary in
connection with the Custodial Agreement or registered in your name to the
Collateral Agent at the address listed on your records.
