Lender to the Borrowers, and each payment made on account of the principal
thereof, shall be recorded by such Lender on its books and, prior to any
transfer of the Note, endorsed by such Lender on the schedule attached to its
Note or any continuation thereof; provided, that the failure of such Lender to
make any such recordation or endorsement shall not affect the obligations of the
Borrowers to make a payment when due of any amount owing hereunder or under the
Note in respect of the Loans made by such Lender.

            2.03 Procedure for Borrowing.

            (a) The Borrowers may request a borrowing hereunder, on any Business

            (b) Upon the Borrowers' request for a borrowing pursuant to Section

forth in Section 5.01 and 5.02 hereof and provided that no Default shall have
occurred and be continuing, make a Loan to the Borrowers (for which all
Borrowers will be jointly and severally liable) on the requested Funding Date,
in the amount so requested.

            (c) The Borrowers shall release to the Custodian no later than 12:00
p.m., New York City time, two (2) Business Days prior to the requested Funding
Date, the Mortgage File pertaining to each Eligible Mortgage Loan to be pledged

            2.04 Limitation on Types of Loans; Illegality. Anything herein to
the contrary notwithstanding, if, on or prior to the determination of any
Eurodollar Rate:

            (a) the Agent determines, which determination shall be conclusive,
that quotations of interest rates for the relevant deposits referred to in the
definition of "Eurodollar Rate" in Section 1.01 hereof are not being provided in
the relevant amounts or for the relevant maturities for purposes of determining
rates of interest for Loans as provided herein; or

            (b) the Agent determines, which determination shall be conclusive,
that the relevant rate of interest referred to in the definition of "Eurodollar
Rate" in Section 1.01 hereof upon the basis of which the rate of interest for
Loans is to be determined is not likely adequately to cover the cost to the
Lenders of making or maintaining Loans; or

            (c) it becomes unlawful for any Lender to honor its obligation to
make or maintain Loans hereunder using a Eurodollar Rate;

then the Agent shall give the Borrowers prompt notice thereof and, so long as
such condition remains in effect, the Lenders shall be under no obligation to
make additional Loans, and the Borrowers shall, either prepay all such Loans as
may be outstanding or pay interest on such Loans at a rate per annum equal to
the Federal Funds Rate plus 0.50% plus the Applicable Margin.

            2.05 Repayment of Loans; Interest.

            (a) The Borrowers hereby promise, jointly and severally, to repay in
full on the Termination Date the then aggregate outstanding principal amount of
the Loans.

            (b) The Borrowers hereby promise, jointly and severally, to pay to
the Lenders interest on the unpaid principal amount of each Loan for the period
from and including the date of such Loan to but excluding the date such Loan
shall be paid in full, at a rate per annum equal to the Eurodollar Rate plus the
Applicable Margin. Notwithstanding the foregoing, the Borrowers hereby promise,
jointly and severally, to pay to the Lenders interest at the applicable
Post-Default Rate on any principal of any Loan and on any other amount payable
by the Borrowers hereunder or under the Note that shall not be paid in full when
due (whether at stated maturity, by acceleration or by mandatory prepayment or
otherwise) for the period from and including the due date thereof to but
excluding the date the same is paid in full. Accrued interest on each Loan shall
be payable monthly on the first Business Day of each month and for the last
month of the Loan Agreement on the first Business Day of such last month and on
the Termination Date; provided, that, the Agent may, in its sole discretion,
require accrued interest to be paid simultaneously with any prepayment of
principal made by the Borrowers on account of any of the Loans outstanding.
Interest payable at the Post-Default Rate shall accrue daily and shall be
payable upon such accrual.

            (c) It is understood and agreed that, unless and until a Default or
Event of Default shall have occurred and be continuing, the Borrowers shall be
entitled to the proceeds of the Mortgage Loans pledged to the Agent, for the
ratable benefit of the Lenders hereunder. At any time while a Default has
occurred and is continuing, upon notice from the Lender, the


                                      -18-

<PAGE>

Borrowers shall promptly deliver all proceeds of the Mortgage Loans pledged to
the Lender hereunder to the Lender.

            2.06 Mandatory Prepayments or Pledge.

            (a) If at any time the aggregate outstanding principal amount of
Loans exceeds the Borrowing Base (a "Borrowing Base Deficiency"), as determined
by the Agent and notice is given to the Borrowers on any Business Day, the
Borrowers shall no later than one (1) Business Day after receipt of such notice,
either prepay the Loans in part or in whole or pledge additional Eligible
Mortgage Loans (which Collateral shall be in all respects acceptable to the
Agent) to the Agent for the account of each Lender, such that after giving
effect to such prepayment or pledge the aggregate outstanding principal amount
of the Loans does not exceed the Borrowing Base.

            (b) The Borrowers shall instruct each Takeout Investor to remit all
Takeout Proceeds directly to the Agent at the account designated in Section 3.01
hereof no later than 3:00 p.m. New York City time. Simultaneously, the Borrowers
shall deliver via facsimile or electronic mail to the Agent a purchase advice
(the "Purchase Advice") and shall indicate on such Purchase Advice the Mortgage
Loan identification number which identified such Mortgage Loan when the Lenders
previously financed the Mortgage Loan. A portion of the Takeout Proceeds in an
amount equal to the Collateral Value of the applicable Mortgage Loans shall be
applied by the Agent to the prepayment of principal outstanding on the Loans. On
the Settlement Date, the Agent shall release and remit to the applicable
Borrower the amount of Takeout Proceeds in excess of the Collateral Value of the
applicable Mortgage Loans (the "Remittance Amount"); provided that on the
Settlement Date (i) there is no Default or Event of Default under this Agreement
or any other Loan Document, (ii) there is no Borrowing Base Deficiency and (iii)
the release to such Borrower of the Remittance Amount will not cause a Borrowing
Base Deficiency. If a Borrowing Base Deficiency exists or would be created by
the release of the Remittance Amount or an Event of Default has occurred and is
continuing, the Agent, for the account of each Lender, shall be entitled to
retain the Remittance Amount, and the Borrowers thereupon shall have no further
rights, title, or interest in and to the Remittance Amount. In the event that
the Purchase Advice indicates that some of the proceeds forwarded to the Agent
do not belong to the Lenders (such amount, the "Excess Proceeds") then (i) the
Borrower shall provide the Agent with a takeout proceeds identification letter
in the form of Exhibit J hereto, and (ii) upon confirmation by the Agent that
the information set forth in the Purchase Advice matches the information that
the Agent has in its possession with respect to the Mortgage Loans, the Agent
shall promptly remit by wire transfer the Excess Proceeds in accordance with the
Borrowers' instructions. If funds are received before 3:00 p.m., New York City
time on a Business Day, but either (A) no Purchase Advice is received or (B)
such funds are not properly identified on the related Purchase Advice (a
"Purchase Advice Deficiency"), then such funds shall be retained by the Agent in
a non-interest bearing account until such Purchase Advice Deficiency is
remedied, and the Mortgage Loan Subject to such Purchase Advice shall not be
released until such Purchase Advice Deficiency is remedied. In no event shall
such Purchase Advice be back-dated to the date of its issuance.

            2.07 Voluntary Prepayments. The Borrowers may at any time and from
time to time prepay the Loan, in whole or in part, without premium or penalty,
upon irrevocable notice


                                      -19-

<PAGE>

to the Lender (in the form of Exhibit I) prior to 1:00 p.m., New York City time,
on the requested date thereof, in the case of the first 500 Mortgage Loans
requested to be released by the Lender on such date, or upon irrevocable notice
delivered to the Lender (in the form of Exhibit I), prior to 1:00 p.m., New York
City time, at least one (1) Business Day prior thereto, in the case of any
Mortgage Loans in excess of 500 requested to be released by the Lender,
specifying the date and amount of prepayment and attaching a schedule of
Mortgage Loans to be released by the Lender in connection with such prepayment.
If any such notice is given, the amount specified in such notice shall be due
and payable on the date specified therein, together with any accrued interest to
such date on the amount prepaid.

            2.08 Extension of Termination Date. At the request of the Borrowers
made at least thirty (30) days, but in no event earlier than ninety (90) days,
prior to the then current Termination Date, the Agent may in its sole discretion
extend the Termination Date for a period to be determined by the Agent in its
sole discretion by giving written notice of such extension to the Borrowers no
later than twenty (20) days, but in no event earlier than thirty (30) days,
prior to the then current Termination Date. Any failure by the Agent to deliver
such notice of extension shall be deemed to be the Agent's determination not to
extend the then current Termination Date.

            Section 3. Payments; Computations; Etc.

            3.01 Payments.

            (a) Except to the extent otherwise provided herein, all payments of
principal, interest and other amounts to be made by the Borrowers under this
Loan Agreement and the Note, shall be made in Dollars, in immediately available
funds, without deduction, set-off or counterclaim, to the Agent at the following
account maintained by the Agent: Account No. 30463591, for the account of the
Agent, Citibank, N.A., ABA No. 021000089, Attn: Whole Loan Operations, not later
than 1:00 p.m., New York City time, on the date on which such payment shall
become due (and each such payment made after such time on such due date shall be
deemed to have been made on the next succeeding Business Day). Each Borrower
acknowledges that it has no rights of withdrawal from the foregoing account. The
Agent shall promptly provide to each Lender (via facsimile or other
transmission) the amount of such payment to be distributed to such Lender along
with the outstanding Loans then held by such Lender, after giving effect to such
payment.

            (b) The amount of such payments distributed to each Lender will be
calculated such that at all times that the aggregate unpaid principal amount of
Loans outstanding hereunder is less than or equal to Morgan Stanley Bank's
Commitment, the Credit Exposure Percentage of Morgan Stanley Bank shall equal
100%.

            (c) Except to the extent otherwise expressly provided herein, if the
due date of any payment under this Loan Agreement or the Note would otherwise
fall on a day that is not a Business Day, such date shall be extended to the
next succeeding Business Day, and interest shall be payable for any principal so
extended for the period of such extension.

basis of a 360-day year for the actual days elapsed (including the first day but
excluding the last day) occurring in the period for which payable.

            3.03 Requirements of Law.

            (a) If the introduction or adoption of or any change (other than any
change by way of the imposition of or increase in reserve requirements included
in the Eurodollar Rate Reserve Percentage) in any Requirement of Law (other than
with respect to any amendment made to any Lender's certificate of incorporation
and by-laws or other organizational or governing documents) or any change in the
interpretation or application thereof or compliance by any Lender with any
request or directive (whether or not having the force of law) from any central
bank or other Governmental Authority made subsequent to the date hereof:

            (i) shall subject any Lender to any tax of any kind whatsoever with
      respect to this Loan Agreement, the Note or any Loan made by it (excluding
      net income or franchise taxes) or change the basis of taxation of payments
      to any Lender in respect thereof;

            (ii) shall impose, modify or hold applicable any reserve, special
      deposit, compulsory Loan or similar requirement against assets held by,
      deposits or other liabilities in or for the account of, advances, Loans or
      other extensions of credit by, or any other acquisition of funds by, any
      office of any Lender which is not otherwise included in the determination
      of the Eurodollar Rate hereunder;

            (iii) shall impose on any Lender any other condition;

and the result of any of the foregoing is to increase the cost to any Lender, by
an amount which such Lender deems to be material, of making, participating in,
continuing or maintaining any Loan or to reduce any amount due or owing
hereunder in respect thereof, then, in any such case, the Borrowers, jointly and
severally, shall promptly pay such Lender such additional amount or amounts as
will compensate such Lender for such increased cost or reduced amount
receivable.

            (b) If any Lender shall have determined that the adoption of or any
change in any Requirement of Law (other than with respect to any amendment made
to such Lender's certificate of incorporation and by-laws or other
organizational or governing documents) regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such Lender
or such corporation could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's or such corporation's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time, the Borrowers, jointly and severally, shall
promptly pay to such Lender such additional amount or amounts as will compensate
such Lender for such reduction.


                                      -21-

<PAGE>

            (c) If any Lender becomes entitled to claim any additional amounts
pursuant to this Section, it shall promptly notify the Borrowers of the event by
reason of which it has become so entitled. A certificate as to any additional
amounts payable pursuant to this Section submitted by the applicable Lender to
the Borrowers shall be conclusive in the absence of manifest error.

principal balance of the Loans outstanding hereunder ("Average Usage") during

the Maximum Credit and the Average Usage, in each case payable monthly in
arrears on the first Business Day of the following month and on the Termination

            (ii) to pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral; and

            (iii) (A) to direct any party liable for any payment under any
      Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Agent or as the Agent shall direct; (B) to ask
      or demand for, collect, receive payment of and receipt for, any and all
      moneys, claims and other amounts due or to become due at any time in
      respect of or arising out of any Collateral; (C) to sign and endorse any
      invoices, assignments, verifications, notices and other documents in
      connection with any of the Collateral; (D) to commence and prosecute any
      suits, actions or proceedings at law or in equity in any court of
      competent jurisdiction to collect the Collateral or any portion thereof
      and to enforce any other right in respect of any Collateral; (E) to defend
      any suit, action or proceeding brought against any Borrower with respect
      to any Collateral; (F) to settle, compromise or adjust any suit, action or
      proceeding described in clause (E) above and, in connection therewith, to
      give such discharges or releases as the Agent may deem appropriate; and
      (G) generally, to sell, transfer, pledge and make any agreement with
      respect to or otherwise deal with any of the Collateral as fully and
      completely as though the Agent were the absolute owner thereof for all
      purposes, and to do, at the Agent's option and the Borrowers' expense, at
      any time, and from time to time, all acts and things


                                      -24-

<PAGE>

      which the Agent deems necessary to protect, preserve or realize upon the
      Collateral and the Agent's Liens thereon and to effect the intent of this
      Loan Agreement, all as fully and effectively as the Borrowers might do.

Each Borrower hereby ratifies all that said attorneys shall lawfully do or cause
to be done by virtue hereof. This power of attorney is a power coupled with an
interest and shall be irrevocable.

            (b) Each Borrower also authorizes the Agent, at any time and from
time to time, to execute, in connection with any sale provided for in Section
4.07 hereof, any endorsements, assignments or other instruments of conveyance or
transfer with respect to the Collateral and to file any initial financing
statements, amendments thereto and continuation statements with or without the
signature of any Borrower as authorized by applicable law, as applicable to all
or any part of the Collateral.

            (c) The powers conferred on the Agent are solely to protect the
Lenders' interests in the Collateral and shall not impose any duty upon the
Agent to exercise any such powers. The Agent shall be accountable only for
amounts that it actually receives as a result of the exercise of such powers,
and neither the Agent nor any of its officers, directors, or employees shall be
responsible to the Borrowers for any act or failure to act hereunder, except for
its own gross negligence or willful misconduct.

            4.05 Performance by Agent of Borrowers' Obligations. If any Borrower
fails to perform or comply with any of its agreements contained in the Loan
Documents and the Agent itself performs or complies, or otherwise causes
performance or compliance, with such agreement, the expenses of the Agent
incurred in connection with such performance or compliance, together with
interest thereon at a rate per annum equal to the Post-Default Rate, shall be
payable by the Borrowers to the Agent on demand and shall constitute Secured
Obligations.

            4.06 Proceeds. If an Event of Default shall occur and be continuing,
(a) all proceeds of Collateral received by the Borrowers consisting of cash,
checks and other near-cash items shall be held by the Borrowers in trust for the
Lenders, segregated from other funds of the Borrowers, and shall forthwith upon
receipt by any Borrower be turned over to the Agent in the exact form received
by such Borrower (duly endorsed by such Borrower to the Agent, if required) and
(b) any and all such proceeds received by the Lenders (whether from a Borrower
or otherwise) may, in the sole discretion of the Agent, be held by the Agent as
collateral security for, and/or then or at any time thereafter may be applied by
the Agent against, the Secured Obligations (whether matured or unmatured), such
application to be in such order as the Agent shall elect. Any balance of such
proceeds remaining after the Secured Obligations shall have been paid in full
and this Loan Agreement shall have been terminated shall be paid over to the
Borrowers or to whomsoever may be lawfully entitled to receive the same. For
purposes hereof, proceeds shall include, but not be limited to, all principal
and interest payments, all prepayments and payoffs, insurance claims,
condemnation awards, sale proceeds, real estate owned rents and any other income
and all other amounts received with respect to the Collateral.


                                      -25-

<PAGE>

            4.07 Remedies. If a Default shall occur and be continuing, the Agent
may, at its option, enter into one or more Interest Rate Protection Agreements
covering all or a portion of the Mortgage Loans pledged to the Agent, for the
ratable benefit of the Lenders hereunder, and the Borrowers shall be responsible
for all damages, judgments, costs and expenses of any kind which may be imposed
on, incurred by or asserted against the Agent relating to or arising out of such
Interest Rate Protection Agreements; including without limitation any losses
resulting from such Interest Rate Protection Agreements. If an Event of Default
shall occur and be continuing, the Agent may exercise, in addition to all other
rights and remedies granted to it in this Loan Agreement and in any other
instrument or agreement securing, evidencing or relating to the Secured
Obligations, all rights and remedies of a secured party under the Uniform
Commercial Code. Without limiting the generality of the foregoing, the Agent
without demand of performance or other demand, presentment, protest,
advertisement or notice of any kind (except any notice required by law referred
to below) to or upon the Borrower or any other Person (each and all of which
demands, presentments, protests, advertisements and notices are hereby waived),
may in such circumstances forthwith collect, receive, appropriate and realize
upon the Collateral, or any part thereof, and/or may forthwith sell, lease,
assign, give option or options to purchase, or otherwise dispose of and deliver
the Collateral or any part thereof (or contract to do any of the foregoing), in
one or more parcels or as an entirety at public or private sale or sales, at any
exchange, broker's board or office of the Agent or elsewhere upon such terms and
conditions as it may deem advisable and at such prices as it may deem best, for
cash or on credit or for future delivery without assumption of any credit risk.
The Agent shall have the right upon any such public sale or sales, and, to the
extent permitted by law, upon any such private sale or sales, to purchase the
whole or any part of the Collateral so sold, free of any right or equity of
redemption in the Borrower, which right or equity is hereby waived or released.
The Borrowers further agree, at the Agent's request, to assemble the Collateral
and make it available to the Lender at places which the Lender shall reasonably
select, whether at the Borrower's premises or elsewhere. The Agent shall apply
the net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale, after deducting all reasonable costs and expenses of every
kind incurred therein or incidental to the care or safekeeping of any of the
Collateral or in any way relating to the Collateral or the rights of the Lenders
hereunder, including without limitation reasonable attorneys' fees and
disbursements, to the payment in whole or in part of the Secured Obligations, in
such order as the Agent may elect, and only after such application and after the
payment by the Agent of any other amount required or permitted by any provision
of law, including without limitation Section 9-615(a)(3) of the Uniform
Commercial Code, need the Lenders account for the surplus, if any, to the
Borrowers. To the extent permitted by applicable law, each Borrower waives all
claims, damages and demands it may acquire against the Agent or any Lender
arising out of the exercise by the Agent or the Lenders of any of their rights
hereunder, other than those claims, damages and demands arising from the gross
negligence or willful misconduct of the Agent or any Lender. If any notice of a
proposed sale or other disposition of Collateral shall be required by law, such
notice shall be deemed reasonable and proper if given at least ten (10) days
before such sale or other disposition. The Borrowers shall remain liable for any
deficiency (plus accrued interest thereon as contemplated pursuant to Section
2.05(b) hereof) if the proceeds of any sale or other disposition of the
Collateral are insufficient to pay the Secured Obligations and the fees and
disbursements of any attorneys employed by the Agent or the Lenders to collect
such deficiency.

            4.08 Limitation on Duties Regarding Preservation of Collateral. The
Agent's and each Lender's duty with respect to the custody, safekeeping and
physical preservation of the Collateral in its possession, under Section 9-207
of the Uniform Commercial Code or otherwise, shall be to deal with it in the
same manner as the Agent or such Lender, as the case may be, deals with similar
property for its own account. Neither the Agent, any Lender nor any of their
respective directors, officers or employees shall be liable for failure to
demand, collect or realize upon all or any part of the Collateral or for any
delay in doing so or shall be under any obligation to sell or otherwise dispose
of any Collateral upon the request of the Borrowers or otherwise.

            4.09 Powers Coupled with an Interest. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

            4.10 Release of Security Interest. Upon termination of this Loan
Agreement and repayment to the Lenders of all Secured Obligations and the
performance of all obligations under the Loan Documents the Agent shall release
its security interest in any remaining Collateral.

<PAGE>

            Section 6. Representations and Warranties. Each Borrower represents
and warrants to the Agent and the Lenders that throughout the term of this Loan
Agreement:

            6.01 Legal Name. On the Effective Date, the exact legal name of the
each Borrower is, and during the four months immediately preceding the date
hereof, such name has been, respectively, American Home Mortgage Corp., American
Home Mortgage Investment Corp., American Home Mortgage Holdings, Inc., American
Home Mortgage Acceptance, Inc. and Columbia National, Incorporated; and no
Borrower has used any previous names, assumed names or trade names except as set
forth on Schedule 4 attached hereto.

            6.02 Existence. The Borrower (a) is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization, (b) has all requisite corporate or other power, and has all
governmental licenses, authorizations, consents and approvals necessary to own
its assets and carry on its business as now being or as proposed to be
conducted, except where the lack of such licenses, authorizations, consents and
approvals would not be reasonably likely to have a Material Adverse Effect; and
(c) is qualified to do business and is in good standing in all other
jurisdictions in which the nature of the business conducted by it makes such
qualification necessary, except where failure so to qualify would not be
reasonably likely (either individually or in the aggregate) to have a Material
Adverse Effect.

            6.03 Financial Condition. The Borrower has heretofore furnished to
the Agent a copy of (a) the consolidated balance sheet of Holdings and its
consolidated Subsidiaries for the fiscal year ended December 31, 2002 and the
related consolidated statements of income and retained earnings and of cash
flows for Holdings and its consolidated Subsidiaries for such fiscal


                                      -30-

<PAGE>

year, setting forth in each case in comparative form the figures for the
previous year, with the opinion thereon of Deloitte & Touche and (b) its
consolidated balance sheet and the consolidated balance sheets of its
consolidated Subsidiaries for the quarterly fiscal period ended September 30,
2003 and the related consolidated statements of income and retained earnings and
of cash flows for Holdings and its consolidated Subsidiaries for such quarterly
fiscal period, setting forth in each case in comparative form the figures for
the previous year. All such financial statements are complete and correct and
fairly present, in all material respects, the consolidated financial condition
of Holdings and its Subsidiaries and the consolidated results of their
operations as at such dates and for such fiscal periods, all in accordance with
GAAP applied on a consistent basis. Since December 31, 2002, there has been no
material adverse change in the consolidated business, operations or financial
condition of Holdings and its consolidated Subsidiaries taken as a whole from
that set forth in said financial statements.

            6.04 Litigation. There are no actions, suits, arbitrations,
investigations (including, without limitation, any of the foregoing which are
pending or threatened) or other legal or arbitrable proceedings affecting any
Borrower or any of its Subsidiaries or affecting any of the Property of any of
them before any Governmental Authority that (i) questions or challenges the
validity or enforceability of any of the Loan Documents or any action to be
taken in connection with the transactions contemplated hereby, (ii) makes a
claim or claims in an aggregate amount greater than $1,000,000, (iii) which,
individually or in the aggregate, if adversely determined, could reasonably be
likely to have a Material Adverse Effect, or (iv) requires filing with the
Securities and Exchange Commission in accordance with the 1934 Act or any rules
thereunder.

            6.05 No Breach. Neither (a) the execution and delivery of the Loan
Documents nor (b) the consummation of the transactions therein contemplated in
compliance with the terms and provisions thereof will conflict with or result in
a breach of the charter or by-laws of any Borrower, or any applicable law
(including, without limitation, the Prescribed Laws), rule or regulation, or any
order, writ, injunction or decree of any Governmental Authority, or any
Servicing Agreement or other material agreement or instrument to which any
Borrower or any of their Subsidiaries is a party or by which any of them or any
of their Property is bound or to which any of them is subject, or constitute a
default under any such material agreement or instrument or result in the
creation or imposition of any Lien (except for the Liens created pursuant to
this Loan Agreement) upon any Property of any Borrower or any of their
Subsidiaries pursuant to the terms of any such agreement or instrument.

            6.06 Action. Each Borrower has all necessary corporate or other
power, authority and legal right to execute, deliver and perform its obligations
under each of the Loan Documents; the execution, delivery and performance by
Borrower of each of the Loan Documents have been duly authorized by all
necessary corporate or other action on its part; and each Loan Document has been
duly and validly executed and delivered by Borrower and constitutes a legal,
valid and binding obligation of Borrower, enforceable against Borrower in
accordance with its terms.


                                      -31-

<PAGE>

            6.07 Approvals.

            (a) No authorizations, approvals or consents of, and no filings or
registrations with, any Governmental Authority or any securities exchange are
necessary for the execution, delivery or performance by each Borrower of the
Loan Documents or for the legality, validity or enforceability thereof, except
for filings and recordings in respect of the Liens created pursuant to this Loan
Agreement.

            (b) Each Borrower is approved by Fannie Mae as an approved lender
and each Borrower and each Servicer is approved by Freddie Mac as an approved
seller/servicer, in each case in good standing (such collective approvals and
conditions, "Agency Approvals"), with no event having occurred or any Borrower
having any reason whatsoever to believe or suspect will occur (including,
without limitation, a change in insurance coverage) which would either make any
Borrower (or any Servicer) unable to comply with the eligibility requirements
for maintaining all such applicable Agency Approvals or require notification to
the relevant Agency. Each Borrower (and any Servicer) has adequate financial
standing, servicing facilities, procedures and experienced personnel necessary
for the sound servicing of mortgage loans of the same types as may from time to
time constitute Mortgage Loans and in accordance with Accepted Servicing
Practices.

            6.08 Margin Regulations. Neither the making of any Loan hereunder,
nor the use of the proceeds thereof, will violate or be inconsistent with the
provisions of Regulations T, U or X.

            6.09 Taxes. Each Borrower and each of their Subsidiaries has filed
all Federal income tax returns and all other material tax returns that are
required to be filed by them and have paid all taxes due pursuant to such
returns or pursuant to any assessment received by any of them, except for any
such taxes as are being appropriately contested in good faith by appropriate
proceedings diligently conducted and with respect to which adequate reserves
have been provided. The charges, accruals and reserves on the books of each
Borrower and each of their Subsidiaries in respect of taxes and other
governmental charges are, in the opinion of each Borrower, adequate.

            6.10 Investment Company Act. No Borrower nor any of their
Subsidiaries is an "investment company", or a company "controlled" by an
"investment company," within the meaning of the Investment Company Act of 1940,
as amended.

            6.11 Collateral; Collateral Security.

            (a) No Borrower has assigned, pledged, or otherwise conveyed or
encumbered any Mortgage Loan or other Collateral to any other Person, and
immediately prior to the pledge of such Mortgage Loan or any other Collateral to
the Agent, for the ratable benefit of the Lenders, the Borrowers were the sole
owner of such Mortgage Loan or such other Collateral and had good and marketable
title thereto, free and clear of all Liens, in each case except for Liens to be
released simultaneously with the Liens granted in favor of the Agent, for the
ratable benefit of the Lenders hereunder. No Mortgage Loan or other Collateral
pledged to


                                      -32-

<PAGE>

the Agent, for the ratable benefit of the Lenders hereunder, was acquired (by
purchase or otherwise) by any Borrower from an Affiliate of any Borrower.

            (b) The provisions of this Loan Agreement are effective to create in
favor of the Agent, for the ratable benefit of the Lenders, a valid security
interest in all right, title and interest of the Borrowers in, to and under the
Collateral.

            (c) Upon (i) receipt by the Custodian of each Mortgage Note,
endorsed in blank by a duly authorized officer of the relevant Borrower and (ii)
the issuance by the Custodian to the Agent of a Trust Receipt therefor the Agent
shall have a fully perfected first priority security interest therein, in the
Mortgage Loan evidenced thereby and in the Borrowers' interest in the related
Mortgaged Property.

            (d) Upon the filing of financing statements on Form UCC-1 naming the
Agent as "Secured Party" and the Borrowers as "Debtors", and describing the
Collateral, in the jurisdictions and recording offices listed on Schedule 2
attached hereto, the security interests granted hereunder in the Collateral will
constitute fully perfected first priority security interests under the Uniform
Commercial Code in all right, title and interest of the Borrowers in, to and
under such Collateral which can be perfected by filing under the Uniform
Commercial Code.

            6.12 Chief Executive Office/Jurisdiction of Organization. On the

            Section 10. The Agent.

            (a) Appointment. Each Lender hereby irrevocably designates and
appoints the Agent as the Agent of such Lender under this Loan Agreement and the
other Loan Documents, and each such Lender irrevocably authorizes the Agent, in
such capacity, to take such action on its behalf under the provisions of this
Loan Agreement and the other Loan Documents and to exercise such powers and
perform such duties as are expressly delegated to the Agent by the terms of this
Loan Agreement and the other Loan Documents, together with such other powers as
are reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Loan Agreement, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Loan Agreement or any other Loan Document or otherwise exist against the Agent.

            (b) Delegation of Duties. The Agent may execute any of its duties
under this Loan Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care.

            (c) Exculpatory Provisions. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be

Person under or in connection with this Loan Agreement or any other Loan
Document (except for its or such Person's own gross negligence or willful
misconduct) or (ii) responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by any Borrower or any
officer thereof contained in this Loan Agreement or any other Loan Document or
in any certificate, report, statement or other document referred to or provided
for in, or received by the Agent under or in connection with, this Loan
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Loan Agreement or any other
Loan Document or for any failure of any Borrower to perform its obligations
hereunder or thereunder. The Agent shall not be under any obligation to any
Lender to ascertain or to inquire as to the observance or performance of any of
the agreements contained in, or conditions of, this Loan Agreement or any other
Loan Document, or to inspect the properties, books or records of the Borrowers.

            (d) Reliance by Agent. The Agent shall be entitled to rely, and
shall be fully protected in relying, upon any Note, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or

document or conversation believed by it to be genuine and correct and to have
been signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel (including, without limitation, counsel to the
Borrowers), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Loan Agreement or any other Loan Document unless it shall first receive
such advice or concurrence of the Lenders as it deems appropriate or it shall
first be indemnified to its satisfaction by the Lenders against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. The Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Loan Agreement and
the other Loan Documents in accordance with a request of the Lenders, and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all the Lenders and all future holders of the Mortgage Loans or any
Interests therein.

            (e) Notices. The Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Agent has received notice from a Lender or a Borrower referring to this Loan
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default". In the event that the Agent receives such a
notice, the Agent shall give notice thereof to the Lenders. The Agent shall take
such action with respect to such Default or Event of Default as shall be
reasonably directed by the Lenders; provided that unless and until the Agent
shall have received such directions, the Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interests of
the Lenders.

            (f) Indemnification. The Lenders agree to indemnify the Agent in its
capacity as such (to the extent not reimbursed by the Borrowers and without
limiting the obligation of the Borrowers to do so), ratably according to their
respective Commitments in effect on the date on which indemnification is sought,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time (including, without limitation, at any
time following the payment of the Loans) be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of, the Commitments,
this Loan Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the Agent under
or in connection with any of the foregoing; provided that no Lender shall be
liable for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting solely from the Agent's gross negligence or willful misconduct. The
agreements in this Section shall survive the payment of the Loans and all other
amounts payable hereunder.

            (g) Agent in Its Individual Capacity. The Agent and its Affiliates
may make loans to, accept deposits from and generally engage in any kind of
business with the Borrowers as though the Agent were not the Agent hereunder and
under the other Loan Documents. With respect to the made by it, the Agent shall
have the same rights and powers under this Loan Agreement and the other Loan
Documents as any Lender and may exercise the same as though it were not the
Agent, and the terms "Lender" and "Lenders" shall include the Agent in its
individual capacity.

Mortgage Loan, each Borrower will save, indemnify and hold such Indemnified
Party harmless from and against all expense, loss or damage suffered by reason

pledge, repledge, transfer, hypothecation or rehypothecation shall impair the
Borrower's rights with respect to the Collateral hereunder.

            11.15 Servicing.

            (a) Each Borrower covenant to maintain or cause the servicing of the
Mortgage Loans to be maintained in conformity with accepted and prudent
servicing practices in the industry for the same type of mortgage loans as the
Mortgage Loans and in a manner at least equal in quality to the servicing the
Borrowers provide for mortgage loans which it owns. In the event that the
preceding language is interpreted as constituting one or more servicing
contracts, each such servicing contract shall terminate automatically upon the
earliest of (i) an Event of Default, (ii) the date on which all the Secured
Obligations have been paid in full or (iii) the transfer of servicing approved
by the Borrowers.

            (b) If the Mortgage Loans are serviced by a Borrower, (i) such
Borrower agrees that the Agent is the collateral assignee of all servicing
records, including but not limited to any and all servicing agreements, files,
documents, records, data bases, computer files, copies of computer files, proof
of insurance coverage, insurance policies, appraisals, other closing
documentation, payment history records, and any other records relating to or
evidencing the servicing of Mortgage Loans (the "Servicing Records"), and (ii)
such Borrower grants the Agent, for the ratable benefit of the Lenders, a
security interest in all servicing fees and rights relating to the Mortgage
Loans and all Servicing Records to secure the obligation of each Borrower or its
designee to service in conformity with this Section and any other obligation of
the Borrowers to the Lenders. The Borrowers covenant to safeguard such Servicing
Records and to deliver them promptly to the Agent or its designee (including the
Custodian) at the Agent's request.


                                      -51-

<PAGE>

            (c) If the Mortgage Loans are serviced by a third party servicer
(such third party servicer, the "Servicer"), the Borrowers (i) shall provide a
copy of the servicing agreement to the Agent, which shall be in form and
substance acceptable to the Agent (the "Servicing Agreement"), (ii) shall
provide a Servicer Notice to the Servicer substantially in the form of Exhibit H
hereto (a "Servicer Notice") and shall cause the Servicer to acknowledge and
agree to the same and (iii) hereby irrevocably assigns to the Lender and the
Lender's successors and assigns all right, title and interest of the Borrowers
in, to and under, and the benefits of, any Servicing Agreement with respect to
the Mortgage Loans. Any successor or assignee of a Servicer shall be approved in
writing by the Agent and shall acknowledge and agree to a Servicer Notice and
Agreement prior to such successor's assumption of servicing obligations with
respect to the Mortgage Loans.

            (d) If the Servicer of the Mortgage Loans is a Borrower or the
Servicer is an Affiliate of a Borrower, such Borrower shall provide to the Agent
a letter from the Borrower or the Servicer, as the case may be, to the effect
that upon the occurrence of an Event of Default, the Agent may terminate any
Servicing Agreement and in any event transfer servicing to the Agent's designee,
at no cost or expense to the Agent, it being agreed that the Borrowers will pay
any and all fees required to terminate the Servicing Agreement and to effectuate
the transfer of servicing to the designee of the Agent.

            (e) After the Funding Date, until the pledge of any Mortgage Loan is
relinquished by the Custodian, the Borrowers will have no right to modify or
alter the terms of such Mortgage Loan and the Borrowers will have no obligation
or right to repossess such Mortgage Loan or substitute another Mortgage Loan,
except as provided in the Custodial Agreement.

            (f) In the event a Borrower or its Affiliate is servicing the
Mortgage Loans, such Borrower shall permit the Agent from time to time to
inspect such Borrower's or its Affiliate's servicing facilities, as the case may
be, for the purpose of satisfying the Agent that such Borrower or its Affiliate,
as the case may be, has the ability to service the Mortgage Loans as provided in
this Loan Agreement.

            11.16 Periodic Due Diligence Review. Each Borrower acknowledges that
the Agent has the right to perform continuing due diligence reviews with respect
to the Mortgage Loans and the manner in which they were originated, for purposes
of verifying compliance with the representations, warranties and specifications
made hereunder, or otherwise, each Borrower agrees that, unless a Default has
occurred (in which case no notice is required) upon reasonable (but no less than
one (1) Business Day's) prior notice to the Borrowers, the Agent or its
authorized representatives will be permitted during normal business hours to
examine, inspect, and make copies and extracts of, the Mortgage Files and any
and all documents, records, agreements, instruments or information relating to
such Mortgage Loans in the possession or under the control of each Borrower
and/or the Custodian. The Borrowers also shall make available to the Agent a
knowledgeable financial or accounting officer for the purpose of answering
questions respecting the Mortgage Files and the Mortgage Loans. Without limiting
the generality of the foregoing, each Borrower acknowledges that the Agent may
make Loans to the Borrowers based solely upon the information provided by the
Borrowers to the Agent in the Mortgage Loan Data File and the representations,
warranties and covenants contained herein,


                                      -52-

<PAGE>

and that the Agent, at its option, has the right at any time to conduct a
partial or complete due diligence review on some or all of the Mortgage Loans
securing such Loan, including without limitation ordering new credit reports and
new appraisals on the related Mortgaged Properties and otherwise re-generating
the information used to originate such Mortgage Loan. The Agent may underwrite
such Mortgage Loans itself or engage a mutually agreed upon third party
underwriter to perform such underwriting. Each Borrower agrees to cooperate with
the Agent and any third party underwriter in connection with such underwriting,
including, but not limited to, providing the Agent and any third party
underwriter with access to any and all documents, records, agreements,
instruments or information relating to such Mortgage Loans in the possession, or
under the control, of the Borrowers. Each Borrower further agrees that the
Borrowers shall reimburse the Agent for any and all out-of-pocket costs and
expenses incurred by the Agent in connection with the Agent's activities
pursuant to this Section 11.15, subject to the proviso of Section 11.03(b).

            11.17 Set-Off. In addition to any rights and remedies of the Lenders
provided by this Loan Agreement and by law, each Lender shall have the right,
without prior notice to the Borrowers, any such notice being expressly waived by
the Borrowers to the extent permitted by applicable law, upon any amount
becoming due and payable by the Borrowers hereunder (whether at the stated
maturity, by acceleration or otherwise) to set-off and appropriate and apply
against such amount any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by the Lender or any
Affiliate thereof to or for the credit or the account of the Borrowers. Each
Lender agrees promptly to notify the Borrowers after any such set-off and
application made by such Lender; provided that the failure to give such notice
shall not affect the validity of such set-off and application.

            11.18 Joint and Several Liability. Each Borrower hereby acknowledges
and agrees that such Borrower shall be jointly and severally liable to the
Lenders to the maximum extent permitted by applicable law for all
representations, warranties, covenants, obligations and indemnities of the
Borrowers hereunder.

            11.19 Intent. The parties recognize (i) that each Loan is a
"securities contract" as that term is defined in Section 741 of Title 11 of the
United States Code, as amended, and (ii) each payment is a "margin payment"
and/or a "settlement payment", as such terms are defined herein.

            11.20 Treatment of Certain Information. Notwithstanding anything to
the contrary contained herein or in any other Loan Document, all Persons may
disclose to any and all Persons, without limitation of any kind, the federal
income tax treatment of the Loans or any of the transactions contemplated by
this Agreement or any other Loan Document (collectively, the "Transactions"),
any fact relevant to understanding the federal tax treatment of the Transactions
and all materials of any kind (including opinions or other tax analyses)
relating to such federal income tax treatment.

            11.21 Replacement by Repurchase Agreement. The Borrowers hereby
acknowledge and agree that this Loan Agreement may at any time and without any
further cost


                                      -53-

<PAGE>

to the Borrowers, in the sole discretion of the Agent, be replaced by a
repurchase facility with substantially similar terms as those contained in this
Loan Agreement. The Borrowers hereby agree to take such action and execute such
documents and instruments as is necessary to effectuate such conversion.

                            [SIGNATURE PAGE FOLLOWS]
